Free Essays on Famous Black Americans

Famous Black Americans During the month of February we focus our attention on famous black Americans as we celebrate black history month. When I think of them many come to mind. That makes it hard to choose just three from the powerful list. After reading several biographies the three that stuck out in my mind were Dred Scott, Harriet Tubman, Halle Berry. Dred Scott is known for suing for his freedom. According to the Missouri Compromise when his master traveled to Illinois (free state) for four years as an army surgeon, he brought Scott with him and Scott was suppose to be free. The court ruled that residence in a free state did not automatically make a slave free. In the meantime, Dr.Emerson (his master) died and his wife became Scott’s owner. She remarried abolitionist Calvin C. Chaffe of Massachusetts. He did not want to be known as a slave owner so Scott tried to bring his suit in federal court, out the Supreme Court decided against Scott because he was black and definitely not a citizen of Missouri. (his hometown) As set out by the Constitution, he had no rights in federal courts, temporary residence in a free state did not make a slave free and the Missouri Compromise was unconstitutional. This limited the power of congress to include slavery from any Northwest Territories that would subsequently apply for admission in the Union. The daughter of Harriet Greene and Benjamin Rass, who were not permitted to marry legally under the law s of slavery, Harriet Tubman lived a brutal childhood. She was often referred to as â€Å"stupid† and received standard whippings regarly. At 13 she was injured by her master, and as a result suffered from occasional blackouts for the rest of her life. At about age 25 she and her brothers planned an escape, but her brothers backed out at the last minute and left Tubman, not being able to read or write the leader of about 300 slaves escaping for freedom. Now she is referred to as the â€Å"conductor...

The Element Tin essays

The Element Tin essays The Element Tin is a soft, silvery-white metal that belongs to group IV of the Periodic Table. Its name may come from the German word, Zinn that describes a soft white metal with a low melting point. It has an atomic number of 50, which also means there are 50 protons in each atom of the element Tin. Tins atomic mass is 118.71. This element can be found in places such as Bolivia, which is the prime producer, Malaysia, Indonesia, Thailand, Zaire, and Nigeria. Its highly crystalline structure gives tin a slight moaning sound when it is bent. Tin has one of the lowest melting points of all metals melting at 449.5F. It remains a liquid until the temperature reaches 4,100F. This is when it turns into gas. Tin is light weighted, ductile, malleable, which means it can be easily bent. With tin being ductile, it can be easily drawn into fine wires or threads. Even though it is relatively weak, when it is mixed with other metals, it can form a wide range of alloys. Tin exist in 3 different forms: gray or alpha, a powdery form of metal stable only at 64F, white or beta, stable between 64F and 322F, and lastly, brittle or gamma, stable between 322F and 449.5F. It also has 10 natural isotopes and 27 artificial isotopes. Although tin is in greater qualities than other metals such, as gold and platinum it still is a rare metal on earth. It only makes up two parts per million of the earths crust. Although some of it is found in its purity, Tin is mostly found mixed with other minerals. One is called cassiterite. Over millions of years the minerals of tin were left in the rocks and were eventually moved by wind, water, and ice. When the minerals were washed and settled on the riverbeds alluvial deposits were formed thus making this the main source of tin minerals. Bronze, a mixture of tin and copper, was the main kind of metal used in the Bronze Age. Countries would sometimes have wars over the minerals used to make this impo...

The Main Types of Chemical Bonds

The Main Types of Chemical Bonds Atoms are the basic building blocks of all types of matter. Atoms link to other atoms through chemicals bonds resulting from the strong attractive forces that exist between the atoms. A chemical bond is a region that forms when electrons from different atoms interact with each other. The electrons that participate in chemical bonds are the valence electrons, which are the electrons found in an atoms outermost shell. When two atoms approach each other these outer electrons interact. Electrons repel each other, yet they are attracted to the protons within atoms. The interplay of forces results in some atoms forming bonds with each other and sticking together. Main Types of Chemical Bonds The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons. The atoms do not always share the electrons equally, so a polar covalent bond may be the result. When electrons are shared by two metallic atoms a metallic bond may be formed. In a covalent bond, electrons are shared between two atoms. The electrons that participate in metallic bonds may be shared between any of the metal atoms in the region. Predict Type of Chemical Bond Based on Electronegativity If the electronegativity values of two atoms are similar: Metallic bonds form between two metal atoms.Covalent bonds form between two non-metal atoms. Nonpolar covalent bonds form when the electronegativity values are very similar, while polar covalent bonds form when the electronegativity values are a little further apart. If the electronegativity values of two atoms are different, ionic bonds are formed.

Competitive Environment Questions Essay Example | Topics and Well Written Essays - 1250 words

Competitive Environment Questions - Essay Example It takes place in imperfect market and monopoly market is a perfect example which provides restraints towards entry. There are no barriers to entry in a perfectly competitive market where the firms are price takers and have no power of price making behavior. Barriers to entry may be structural, legal or strategic (Besanko, et al, -2010, p. 473). Structural barriers affect the decisions associated with the cost and demand of the firms and it may occur due to economies of scale and network effects. Legal barriers from its name can be said to be barriers like patents, license etc from the ruling body. In case of strategic barriers, it includes various decisions made by the firms in restricting the entry of other firms with application of methods like innovative dealing arrangements, first mover advantage, and unique advertising and product differentiation techniques and so on (Competition and Barriers to Entry, 2007, p.3). 1 (b) Comment generally on the impact of ‘the Internetâ₠¬â„¢ on such barriers Internet auction market is an example of structural barriers to entry. The concept of positive network externality plays an important role in this case. The concept of positive network externality states that when a firm’s product is more attractive to a given customer base then more of the product is used by other consumers. Recent eBay. Com has emerged as one of the internet auction leader and its huge database offers the customers a wide array of products to be purchased at a time. The huge volume of transactions on this particular website is a typical example of barriers to entry towards other internet auction companies as in case of eBay they make huge money through the basis of commissions on transactions. Now a newcomer will have to either huge money which will not cover his cost or it will not be attractive as eBay because it already has a great market reputation and mammoth customer base (Besanko, et al, -2010, p. 473).The concept of strategic b arriers to entry is also associated with the structural barrier concept as the various companies through innovative production differentiation techniques like innovative advertisement, promotions, lucrative offer also try to capture markets as for example jabong.com, flipkart.com, snap deal.com and holds parity with the assumptions of monopolistic competition. In case of the airlines industry, with the use of internet has helped various travel agents reap a huge benefit through third party transactions on commission basis which affects the traditional travel agencies. Thus legal barriers are sometimes imposed (Dembrower & Grenblad, 2003, p. 3). 2. Explain and give examples of ‘collusive behaviour’, which is common in ‘Oligopolistic’ markets, AND identify the conditions necessary for ‘collusive agreements’ to survive in the long term. In oligopolistic markets various players cater to the same industry as for example in the soft drinks market two dominant players are Coca Cola and Pepsi. They formulate and implement optimal strategies against their rivals in order to make them worse off by calculating on their respective reaction functions (Bertrand game). Thus the

STUXNET Research Paper Example | Topics and Well Written Essays - 1250 words

STUXNET - Research Paper Example As the engineer hooked the computer to the Internet, the worm spread far and wide. How the Stuxnet Worm Spread The Stuxnet worm started to spread in March 2010, but it took its first variant about three months from then to appear. As people learnt about the existence of the worm on 15 July 2010, the servers for two mailing lists were attacked with the distributed denial-of-service on the industrial-systems security. Although at that time, the source of attack could not be worked out, yet it was suspected to be the Stuxnet worm. As a result of the attack, one of the two mailing lists got disabled, thus interrupting a very important informative source for the factories and the power plants. Two more variants of the Stuxnet worm surfaced; the first in March 2010 and the second in April 2010. In the authors’ opinion, the second and substantially improved variant showed up because of slow progression of the Stuxnet worm. The third variant that surfaced in April 2010 had only minor improvements. There is a build time-stamp in thee worm that starts from 3 February 2010. According to the report delivered by the Sky News on 25 November 2010 in the United Kingdom, an anonymous source whose IT security organization was also unidentified sent the news to Sky News that the black market had received a variation of the Stuxnet worm, but there was lack of consensus among the security experts over this matter. How the Stuxnet Worm Works Stuxnet makes use of vulnerability just like Windows uses the shortcut files to expand to new systems. The Stuxnet worm’s design was bottom-up so that it could effectively attack the systems implemented for the management of industrial networks like chemical manufacturing facilities and power plants as well as the systems of Supervisory Control and Data Acquisition (SCADA). In the start, the Stuxnet worm was thought to progress through such removable drives as USB sticks. However, about two weeks after the Stuxnet worm was first id entified, researchers of the Kaspersky Lab working in Moscow found that an unknown security flaw in the sharing of printer resources by the Windows could also help the Stuxnet worm spread. Microsoft found a way to fix this vulnerability with MS10-061 which varies in risk from one type of windows to another. â€Å"At least one aspect of what Stuxnet does is to take control of the process and to be able to do†¦whatever the author or programmer wants it to do. This has potentially devastating consequences, and there needs to be a lot more attention focused on it† (Weiss cited in â€Å"‘Stuxnet’ Worm Far†). The Target of the Stuxnet Worm The main target of the Stuxnet worm is the Siemens software. One trait that distinguishes the Stuxnet worm from most viruses that have been identified to date is that it remains silent till the time the worm locates Siemens software in the Windows system. Once the Siemens software is found, the Stuxnet worm exploits up to four 0-day attacks. The Stuxnet worm infected the SCADA systems in 14 functional plants of Siemens, though the infections could not hold the infected plants’ productions. According to the IDG News reports, the Stuxnet worm has infected systems at the Siemens plants in North America, Korea, and the UK, while the maximum infections have so far been made in the plants operating in

Media Convergence Essay Example | Topics and Well Written Essays - 1500 words

Media Convergence - Essay Example Or as Jenkins (2006) states, there is a cooperation between all multiple media industries, and media audiences will look for information where they can find it. This essay will look at convergence and what is meant by it, and will look, briefly, at the dangers of convergence, then will examine the Astral-Bell merger and analyze the merger from the voices of the people and the voices of the individuals who are behind the merger. Media Convergence According to Jenkins (2004) there is an inherent danger in media convergence, in that the multinational media conglomerates have the potential, and live up to this potential, to dominate every sector of the entertainment industry. Thus, the power elite had the potential to rule the airwaves, putting out its message to the masses, and the message is the message that benefits the corporations and the powerful (Brenkman, 1979). The media may be associated with large structural forces (Havens, et al., 2009). And the message may become more like p ropaganda, which makes the mass media more of a propaganda machine than a marketplace for free ideas (Murray, 2005). Giroux (2004) states that one of the dangers of media convergence, when certain corporations become too powerful, is that the message that goes out to the people is the message that benefits the corporations that own these multi-media conglomerates, which is the message of the neo-liberal – low taxes, deregulation and private enterprise is good, the opposite is bad, and an unequal distribution of wealth in society is a good thing. This is because the corporations that own these conglomerates are the very corporations that would benefit the most in this kind of society of profit above all else. Media convergence has the power to do the bidding of powerful people (Rossman, 2004), such as when Clear Channel, which is a multimedia conglomerate based in the United States, organized a boycott against the country group The Dixie Chicks, after the lead singer, Natalie Maines, told a crowd that she was embarrassed to be from the same state as George W. Bush, and Clear Channel, wanting to get favorable legislation for its plans to expand, organized the boycott to please the Bush Administration. In short, media convergence has the potential for great harm. Too much power in any one hands would cause the marketplace of ideas to falter, and the message that is disseminated will be the message that is crafted by this particular entity. It is in this context that the merger between Bell and Astral will be examined. The Bell-Astral Merger The View of the People According to Winseck (2012), the Bell-Astral merger refer to the fact that Bell is attempting to buy Astral media, and this would represent a major deal between the largest Telecom-Media-Internet conglomerate in the country, and they would have revenues of over $22 billion. Winseck (2012) states that the merger would mean that the country would have lost an independent station, which is what Astra l is, having revenues of just over $888 million in 2010. Winseck (2012) looks at this in the context of the Ronald Coase, economist, idea that the two ways of dealing with business environment uncertainties are the market and the hierarchies, and that the Bell-Astral merger would be essentially elevating the hierarchies over the markets. If the merger goes through, according to Winsec

Crimonology Essay Example | Topics and Well Written Essays - 750 words

Crimonology - Essay Example Biological influences on white collar crime are evident in sex differences between males and females. Sex of a person makes it possible to experience various life consequences. The belief that females, who are supposedly physically more weak, are mistreated more often is also inaccurate. Aside from rape, the only individual crime for which women are victimized more than men is robbery with contact. Men are twice as likely to be the victim of an assault or a robbery and 50 percent more likely to experience some crime of theft. Men are also the victims of strangers more than females (Friedrichs, 2006). Therefore, the idea that physically weaker people constantly fall prey to the criminal has no foundation in fact. Neither females nor older people are particularly prone to white collar crime. But, the lifestyles of these community groups may explain this fact better than their actual vulnerability to criminals. The advantage of this theory is that it explains roots of white collar crime , thus it does not take into account motivational factors and personal intentions of a criminal. Human biology and genetics are the two personal attributes most closely tied to antisocial behavior. Heredity and race are also related. ... ore frequently victims of white collar crime than others, while whites experience property crimes at higher rates than other ethnic and racial groups. For white collar crime, robbery accounts for the higher rate experienced by blacks (Friedrichs, 2006). It is still difficult to define the motivations of women when they commit their white-collar crimes at the workplace. But I am personally apt to think that if women have obtained such top positions at their companies - white-collar positions, they can hardly commit their crimes being motivated by poverty (according to economic marginalization thesis). Women rather try to cash in, in different ways, on their top-level positions. Thus, here opportunity thesis and sometimes, masculinity thesis can be more applicable in order to explain the motivation. As well, criminological theory states that opportunity is a more intense motivation for committing white-collar crimes. According to this theory, people who have achieved a lot on their liv es and have satisfied their needs as a result will need more goods to exchange with others, but not to use. Thus, this need for more possessions (or greed) can make people break the law and perpetrate crimes to receive what they want. Psychological predisposition may lead to antisocial inclinations and increase a possibility of criminal behavior patterns. The cultural ties associated with family income, race, and ethnicity also affect with whom one associates and the places of those associations. Housing, transportation, privacy, and leisure-time factors are related to income as well as to racial and ethnic segregation (Sutherland and Cressey 2001). To the extent that white collar crime varies according to place and event, individuals from different income levels and racial and ethnic

Effects of flicker on reading comfort (part 2) Essay

Effects of flicker on reading comfort (part 2) - Essay Example Two types of questionnaire, an initial questionnaire to identify the previous experience of discomfort and a symptom questionnaire were used. Results: The results indicated insignificant difference between discomforts caused by sustained reading and using computer. The condition of 50 Hz induced the greatest impact on reading comfort compared to DC. The most affected symptoms of discomfort were vision discomfort followed by eyestrain, blurred vision and headache. The mean difference of 75 Hz, 100 Hz and 140 Hz compared to DC lighting situation was not significant. Conclusion: The study shows that reading under 100 Hz LEDs light has no different effects on comfort than reading under LEDs light powered on DC. In addition, the study shows insignificant difference between discomfort induced by reading and by computer use in terms of incidence and nature. Further studies are required with larger and balanced sample size, different direction of illumination and longer period of reading tim e to address the possible limitations of this experiment. Methods Participants Students of the University of New South Wales (UNSW) were invited by posters and emails to participate in the experiment. Participants who completed the experiment received a nominal reward. The inclusion criteria were good binocular vision, lack of ocular and systemic abnormalities that possibly influence reading ability, and age had to be between 19 to 30 years old since light sensitivity often higher at this age group. The exclusion criteria were any known case of migraine or photosensitive epilepsy. A total number of 18 students were recruited (2 male and 16 female), all signed an informed consent form prior commencing the study. Ethics and the study protocol were reviewed and approved by the UNSW Human Research Ethics Advisory (UNSW HREA) Panel. Design and Procedure In a double masked randomized crossover study, discomfort symptoms were self-reported by using two types of questionnaires; an initial q uestionnaire and symptoms questionnaire. The participants had to attend five reading sessions under LED light, but with different rate of flicker in each session. They were randomly assigned to the sessions by Latin squares, and the reading sessions had to be separated by at least one day. At the beginning of the first session, the initial questionnaire had to be completed, whereas symptom questionnaire had to be filled immediately at the beginning and at the end of every session to evaluate reading discomfort. During the reading sessions, the ambient light was turned off, and the room was completely dark, so the only light source was that installed in lighting booth. The booth was positioned on a table, and a â€Å"twilight† novel was placed inside the booth directly under the light. Each subject had to read a part from the book on every session for 30 minutes with the habitual glasses. Comfortable sitting was enhanced by providing an adjustable chair placed in front of the booth to read with habitual reading posture. Questionnaires Two types of questionnaires were used in the study: the initial questionnaire and the symptom questionnaire. The initial questionnaire was designed to examine the previous experience of discomfort related to reading and computer use and to detect unknown cases of photosensitive epilepsy or migraine. The first part of the questionnaire was

Refer to a specific episode that you have watched to support your evaluation. The Simpsons confirm to some stereotypical sitcom genre stereotypes, but ultimately subvert them by proving to dysfunctional. A sitcom is a 30 minutes programme, which contains humour and different types of comedy. In this essay, I will evaluate the extant to which the episodes The Simpsons roasting on an open fire Sitcoms of the past showed the ideal family; always nuclear a mum, dad and kids. The dad was respected and it had a bread winner mum-housewife cooks and cleans with two kids, the son is mostly the clever one and the daughter follows in the footsteps on her mother. E.g. leave it to beaver and the Cosby show. Sitcoms are popular because they relate to real people, take the Simpsons as an example, Homer can relate to people that an unorganised an lazy people; Marge is a representation, responsible, hardworking housewife; in Lisa we can relate to nerdy person and through Bart can relate to people that are not very clever and like skate boarding and rock music. The Simpsons opening scene starts with the title effect which Christmas snow effect with jungle bells and at the start of the scene there are late to a special Christmas concert where they arrive there children will be singing and when they arrive we know that the parents are tired and Homer drives fast and hits the car at this opening scene is called The Simpsons Roasting on an open fire which we know that there will be trouble.

They have their good and bad times. In this essay, I will be evaluating to what extent The Simpsons follow the conventions of a stereotypical Sitcom. To support this, I am going to be referring in detail to an episode of The Simpsons called The Simpsons Roasting On An Open Fire. A Sitcom is a 30 min comedy T.V show about a family; in a sitcom the main character is usually the father. I will analyse how sitcoms have changed over time, Sitcoms use to only air upper/middle class familys which were white familys only, but as time went past ant the racism cooled down, they started to air black familys as well, in my opinion The Simpsons are made bright yellow is to make a joke out of sitcoms because sitcoms use to be aired as white people only in the past. The opening sequence in the episode starts with the title The Simpsons Roasting On An Open Fire with some jingle bells and Christmas effects. Then it jumps into Homer Marge driving to their childrens concert in dangerous situations. Marges voice makes her sound really tired, but homers voice just makes him sound silly, not the typical father you would find in other Sitcoms. Marge actually believes that Barts ironic humour is right; it shows that they must care for Bart more in my opinion. From analysing The Simpsons Roasting on an open fire I have seen that the orientation is getting ready for Christmas expenses. Evaluate the extent to which The Simpsons follow the conventions of a typical sitcom. Refer to a specific episode that you have watched to support your evaluation. A sitcom is another word for situation comedy for example, Leave It to Beaver which was the first US sitcom in the 1950s. A sitcom is usually about a family consisting of dad, mum and two children. This is called a nuclear family. The situation or setting that the story takes place in is their home. Sitcoms are shown on TV and usually lasts for half an hour. It is a comedy and you can usually hear a live studio audience in the background. In the past, sitcoms always showed happy conventional white families who were always perfect. Dad was always the breadwinner and had a highly respectable job and the mother was always very attractive and happy to stay looking after the home and children. In Leave it to Beaver the son was a high achiever like the father and the daughter wanted to be a homemaker like mum. Sitcoms have changed over time because today mothers may now have careers and dads have to have respect for their wives just as they have respect for themselves. These days family problems are not hidden and people want to see realistic life-like situations in sitcoms. However although sitcoms started to show other families like a black family in The Cosby Show, they were still upper middle class. The Simpsons was the first sitcom to really show problems faced by working class families. Sitcoms are popular because all ages can watch it for fun and enjoyment; charaters of all ages provide someone for everyone to identify with. The Simpsons are even more popular because as an animation they can also have other celebrity characters such a Barry White and Michael Jacson. The Simpsons episode Simpsons Roasting On An Open Fire had an opening sequence where the title came up through snowflakes and jingly music. We hear Marge speaking to Homer saying Oh slow down Homer! which shows she is worried. Homers response, We dont have time to slow down were late makes us think that he is stubborn, wanting things his way and that he doesnt think too much about the safety of his wife and baby. This opening sequence immediately lets us see that this family is not perfect but realistic. We can see from this episode that The Simpsons does follow the traditional narrative structure. The audience gets orientation from not only the opening sequence but also the next couple of scenes where they were at the school Christmas performance, putting up Christmas lights and the children asking for expensive difficult presents.

Molecular Weight Effect of Different Grades of HPC Polymer

Molecular Weight Effect of Different Grades of HPC Polymer Introduction Bioavailability enhancement Wet media milling + spray drying Issues have impact on dissolution performance Novelty of the work Objective Material and methods wet stirred media milling Spray dryer Characterization techniques Results and discussion Physical stability of the milled precursor suspensions Drug breakage kinetics Formation of the NCMPs via spray drying of the precursor drug suspensions Impact of different polymers on the drug dissolution from NCMPs PVP-K30 HPMC-E3 HPC-SSL, HPC-SL, HPC-L Molecular weight effect of different grades of HPC polymer on drug dissolution performance and stability It is estimated that a large percentage of newly developed drug compounds have limited bioavailibity due to their poor water solubility and very slow dissolution rate [1]. According to the Biopharmaceutics Classification System (BCS), class II drugs are categorized as poorly water soluble and highly permeable in human body [2]. To achieve the therapeutic efficacy of these drugs it is very essential to enhance the bioavailability by increasing the solubility or dissolution rate. A number of approaches have been developed over the time to resolve this issue. The reduction of drug particles size to sub-micron or nanometer has been one of the most popular and effective approaches of all [3-6]. By reducing the particles size order of magnitude, specific surface area of the particles increased radically and enhances the rate of absorption and dissolution [7, 8], according to the Noyes-Whitney equation [9]. Drug nanoparticles production technologies are classified into Bottom-up or Top-down or combination of both. The bottom up techniques include precipitation using supercritical fluid, liquid anti-solvent precipitation, and evaporative precipitation, where small drug particles are produced from drug molecules dissolved in organic solvent [10, 11]. In case of top-down approaches, the particles are reduced to the nanometer range [11]. High pressure homogenization [5] and wet media milling [3] are included in top-down approaches. To prepare drug nanosuspension, wet stirred media milling (WSMM) has achieved the most popularity because of its effectiveness, robustness, scalability, high drug loading, and low polymer side effects [5, 12, 13]. Due to many advantages of drug solid dosage form, it is the most popular dosage form to the patients/clinicians. To encounter this high demand, drug nanosuspensions are usually converted into nanocomposite microparticles (NCMPs) using different drying techniques and incorporated into standard solid dosage forms such as tablets and capsules [13, 14]. Vacuum dryer [15, 16], spray-freeze dryer [17, 18], spray dryer [19, 20], and fluidized bed [17] are very prevalent and widely used drying tools in the pharmaceutical industries. Among all the drying techniques, spray drying has already got attention due to its energy intensive, continuous and scalable drying process characteristics and ability to produce micro to nano-sized particles with a very narrow distribution within a very short time frame [21]. Albeit particle size reduction is an effective technique for bioavailability enhancement, stability issue has always been critical for the efficacy of the drug products. In the nanosuspension, drug particles start losing their specific surface area by aggregation due to relatively high surface energy and specific surface area and also for enhanced Brownian motion [22]. For the prevention of aggregation in the wet media and having better stability, polymers and/or surfactants are added to the suspension as stabilizers. These stabilizers provide stability by electrostatic or electrosteric mechanisms [22]. Steric stability provided by the polymer is drug specific. Only few polymers can help to reduce the particle size of a specific drug down to nanometers. Therefore, selecting a proper stabilizer for a specific drug is a very complex process and cannot be generalized easily [23]. Thus, having a better insight about the polymer properties is very crucial to figure out the right stabilize r for a particular drug. Molecular weight of the polymer is a very significant property of polymers, which determines the capability for steric stabilization along with solution properties [24, 25], regulates mechanical property of the films [26], and controls the drug release during oral administration [27]. Consequently, optimum MW and polymer concentration may help to get the best stabilization performance during and after milling, and faster drug release from the composites.   Choi et al. [16] investigated the impact of lower range MW (11,200-49,000 g/mol) of hydroxypropyl cellulose (HW) on itraconazole suspension production and their recovery from the drug composites. In that work, HPC was used solely with the same concentration, and dissolution performance study was absent.   Sepassi et al. [28] studied MW effect of two different polymers hydroxypropylmethyl cellulose (HPMC) and polyvinylpyrrolidone (PVP) on the particle size reduction of milled nabumetone and ha lofantrine suspensions; however, drying and dissolution rate were not studied. Li et al. [29] studied the MW and concentration effect of hydroxypropyl cellulose (HPC) on the dissolution performance of poorly soluble drug griseofulvin (GF) in presence/absence of sodium dodecyl sulfate (SDS) as surfactant. In that investigation, drug nanosuspension was coated and dried on to the surface of pharmatose using fluidized bed technique and also determined the optimum concentration and MW effect of HPC for complete release of the drug particles during dissolution. To authors best knowledge, no comprehensive and systematic study has been performed so far to get the insight about the head to head comparison of different polymers performance and MW effect of the same polymer on the suspension stability after milling and during dissolution of NCMPs produced via spray drying. It is known from prior study that the combined use of polymers and surfactants provide a synergistic effect leading to better stability in the nanosuspension than individual stabilizers [30, 31]. Due to the side effects of surfactant, it is always expected to use minimal amount in the formulation. If only the use of polymer can provide substantial stability in the nanosuspension and immediate release of the drugs in the dissolution from NCMPs, then it is more viable than using surfactant.   Therefore, this study aims to develop an understanding of the polymer MW and different polymer effect on the physical stability of Itraconazole nanosuspension and drug dissolution fr om the composites. Itraconazole (ITZ) suspensions were milled in a WSMM and the nanocomposite particles were produced using a co-current spray dryer. Three different polymers HPC, PVP, and HPMC were used at 4.5% (w/w) concentration to see the polymer effect and for MW effect, three grades (SSL, SL, and L) of HPC having different MW were used. Laser diffraction, SEM, UV- spectroscopy, XRPD, and DSC were used to analyze the drug suspension and composite particles. Dissolution test of the NCMPs were performed by a USP II paddle apparatus. Materials Itraconazole (ITZ), is an antifungal drug with a water solubility 0.13 mg/L (at pH-7 and 25  °C), is a sparingly water soluble drug belong to the BCS Class II was purchased from Jai Radhe Sales (Ahmedabad, India) and was used as-received condition. Three different polymers, hydroxypropyl cellulose (HPC), hydroxypropylmethyl cellulose (HPMC), and polyvinylpyrrolidone (PVP) were used as polymers. Three grades (SSL, SL, and L) of HPC with ~40, ~100, and ~140 kDa molecular weight, respectively, were donated by Nisso America Inc. (New York, NY, USA) and used for steric stabilization. Polymeric stabilizers Methocel E3 grade HPMC and PVP Kollidon 30 were donated by Dow Chemical (Midland, MI, USA) and BASF Corporation (Florham Park, NJ, USA) respectively. Sodium dodecyl sulfate (SDS) is an anionic surfactant used as a wetting agent during dissolution and provide electrostatic stabilization in the suspension, was purchased from Sigma Aldrich (Milwaukee, WI, USA). Zirmil Y grade wear-re sistant yttrium-stabilized zirconia (YSZ) with a median size of 430  µm (400  µm nominal size) was used as the milling media and purchased from Saint Gobain ZirPro (Mountainside, NJ, USA). Methods Wet Stirred Media Milling (WSMM) The presuspension (before milling) was prepared following the same procedure used in Afolabi et al. [32]. All the suspension formulations are tabulated below in Table 1. API (Itraconazole) concentration was kept constant at 10% (w/w) and polymer concentration was 4.5% (w/w) for all the formulation. All the concentrations are reported with respect to deionized water (200g). The formulation with 2.5% (w/w) HPC-SL and 0.2% (w/w) SDS was used as a baseline formulation, because from earlier study it was found to be the optimum for fastest and complete drug release from the composite powders. Prepared drug suspension was milled in a Netzsch wet media mill (Micorcer, Fine Particle Technology LLC, Exton, PA, USA) with 80 ml chamber; 50 ml of the chamber was filled with 400  µm (nominal size) Zirconia beads, which is the milling media and a screen with 200  µm opening was used to hold the beads into the chamber and allowing only the passage of the suspension. A shear mixer (Fisher Scientific Laboratory Stirrer, Catalog No. 14-503, Pittsburgh, PA) was used to prepare the suspension prior to transfer into the holding tank of the miller. The suspension was pumped through a peristaltic pump and was milled under the following conditions: suspension flow rate 126 ml/min, rotor speed 4000 rpm corresponding to a tip speed of 11.7 m/s. To keep the suspension temperature below 35  °C, milling chamber and holding tank both were equipped with a chiller (Advantage Engineering Greenwood, IN, USA).   All the parameters were selected from the earlier work done by Afolabi et al. [31]. To determine the breakage kinetics, particle sizes were measured at different time intervals up to 65 minutes and the suspension were refrigerated at 8  °C for one day before spray drying. Preparation of NCMPs via Spray Drying The prepared nanosuspesions were dried within a day of milling using a spray dryer (4M8-Trix, Procept, Zelzate, Belgium) running in a co-current flow set up. All the operating conditions were taken from Azad et al. [19].The suspensions were atomized at 2 bar atomizing pressure using a bi-fluid nozzle having 0.6 mm tip diameter. In each run, ~120 gm nanosuspensions were sprayed at 1.3-1.6 g/min spray rate using a peristaltic pump (Makeit-EZ, Creates, Zelzate, Belgium). Drying air was fed co-currently from the top of the column at 120  °C temperature and 0.37-0.40 m3/min volumetric flow rate. To avoid sedimentation of the drug particles during spraying, the suspension was stirred using a magnetic stirrer throughout the run. A Cyclone separator was used at 54-70 mbar differential pressure to separate the NCMPs from the outlet air stream and collecting them in a glass jar. The dried powders later on were used for powder sample characterization e.g., XRD, DSC, Rodos, and dissolutio n testing. Particle Size Analysis Particle size distributions of the suspensions were measured at different time interval during milling and after 7-day storage in the refrigerator by laser diffraction (LD) technique using Coulter LS 13 320 (Beckman Coulter, Miami, FL). All the steps involved for measuring PSDs of the suspensions were followed from Li et al. [29]. During sample addition, intensity was maintained between 40-45% while obscuration was below 8%. Mie scattering theory was used to compute the volume-based PSDs in the software. Refractive index value is 1.68 for ITZ and 1.33 for deionized water (medium). Before measuring the PSDs, 2 ml suspension sample was collected from the outlet of the mill chamber and diluted with 5 ml of the respective stabilizer solution using a vortex mixer (Fisher Scientific Digital Vortex Mixer, Catalog no: 0215370, Model No: 945415, Pittsburgh, PA) at 1500 rpm for 1 min. The Particle size distributions (PSDs) of produced NCMPs via spray drying were measured by Rodos/Helos laser diffraction (LD) system (Sympatec, NJ, USA) based on Furnhofer theory with dry powder dispersion module. On the sample chute of the Rodos dispersing system, just about 1 g of the sample was placed. To feed the samples, the sample chute was vibrated at 50% settings and 0.1 bar dispersion pressure was imposed to suck in the falling powder through the sample cell of the laser diffraction system. Determination of Drug Content in the Composite Powders Drug content of the composite powders were measured by assay testing. ITZ solubility is - in dichloromethane (DCM). 100 mg of the NCMPs was dissolved in 20 ml DCM, sonicated for 30 mins to ensure all the ITZ is dissolved in the solvent and then they were allowed to sediment overnight. An aliquot of 100  µl is taken from the supernatant and diluted to 10 ml with DCM. The absorbance of all the samples was measured at 260 nm wavelength via Ultraviolet (UV) spectrophotometer (Agilent, Santa Clara, CA, USA). Six replicates were prepared from each NCMP formulation to calculate mean drug content and percent relative standard deviation (RSD). Scanning Electron Microscopy (SEM) SEM imaging was performed to understand the morphology and particle size of the ITZ particles before and after milling. SEM images of as-received ITZ and baseline formulation was taken using a LEO 1530 SVMP (Carl Zeiss, Inc., Peabody, MA, USA) SEM machine. Approximately, 0.1 ml milled suspension sample was placed on top of a silicon chip (Ted Pella Inc., Redding, CA, USA), and then on top of a carbon specimen holder. The sample was placed into a desiccator for overnight drying. The samples were then sputter coated with carbon before analyzing [33]. X-ray Powder Diffraction (PXRD) The crystallinity of the as-received ITZ, physical mixture of ITZ-excipinets, and spray dried powders were analyzed using PXRD (PANalytical, Westborough, MA, USA), provided with Cu KÃŽÂ ± radiation (ÃŽÂ »= 1.5406 Ã…). The samples were scanned at a rate 0.165 S-1 for 2ÃŽÂ ¸ ranging from 5 to 40 °. Differential Scanning Calorimetry (DSC) DSC of the as-received ITZ, Physical mixture of ITZ-excipients, and spray dried powders was performed using a Mettler-Toledo polymer analyzer (PolyDSC, Columbus, OH, USA). The samples were heated at a rate of 10  °C/min within a range of 25-220  °C under nitrogen gas flow. With the help of the integrated software of the machine, melting temperature Tm and fusion enthalpy ΆHm were determined. Dissolution Testing Dissolution of ITZ from the as-received drug, and spray dried composite powders were determined via a Distek 2100C dissolution tester (North Brunswick, NJ, USA) according to the USP II paddle method.   The dissolution medium was 1000 ml SDS buffer with 3.0 gm/ml concentration at non-sink condition.   The medium was maintained at 37  °C temperature and 50 rpm paddle speed.   The composites were weighed equivalent to a dose of 20 mg of ITZ. Composites were poured into the dissolution medium and manually 4 ml of samples were taken out at 1, 2, 5, 10, 20, 30, and 60 min. Aliquots of the samples were filtered using a 0.1  µm PVDF membrane type syringe filter to avoid any effect of undissolved drug during UV spectroscopy measurement. The absorbance of ITZ dissolved was measured via UV spectroscopy (Agilent, Santa Clara, CA, USA) at 260 nm wavelength. The blank was measured using SDS buffer at the beginning. The amount of drug dissolved was measured using a calibration curve generated from drug concentration vs. absorbance (R2=0.9995 with p Apparent Shear Viscosity of Milled ITZ Suspensions The apparent shear viscosity of the nanosuspension was measured by following the procedure from Afolabi et al. [32], using R/S plus rheometer (Brookfield Engineering, Middleboro, MS, USA). To impart controlled shear rate on the samples from 0 to 1000 1/s in 60 s, a coxial cylinder (CC40) was used. To control the temperature the jacket temperature was kept constant at 25 ±0.5  °C. Drug nanoparticles formation and physical stability of the milled suspensions The formulation of the milled drug (ITZ) suspensions are presented in Table 1. Drug (ITZ) nano suspension was first produced in presence of both steric and an anionic surfactant, SDS (Run 1). Due to the synergistic effect of HPC and SDS [31], Run 1 was used as a baseline to assess the impact of various stabilizers (HPC, HPMC E3, PVP k30, and SDS) in their breakage kinetics and physical stability of the resulting suspensions. This baseline formulation was found to be the optimum formulation from a previous work performed by Meng et al [29]. The molecular weight effect of HPC was then studied in absence of SDS surfactant (Run 2-4) using three different grades of HPC; SSL, SL, and L grades having molecular weight ~40, ~100, and ~140 kDa, respectively. The apparent shear viscosity of all the formulations (Run 1-7) are represented in Figure 1. Formulations with 2.5% (w/w) HPC-SL/SDS, 4.5% (w/w) HPC-SL, and 4.5% (w/w) HPC-L (Run 1, 3, and 4) are showing near Newtonian behavior, indicating the extent of aggregation is very low. Milled drug suspensions stabilized by SDS or polymer alone (except HPC-SL and HPC-L) are showing significant shear-thinning behavior, indicating significant amount of aggregates.

America’s Personal Values, Compared Essay -- Literary Analysis

America’s Personal Values Compared Great Indian authors have written grand epics that depict heroic characters performing virtuous deeds. Many of these epic tales feature fearsome and godly battles, while others highlight the soft side of human emotions. Despite seemingly unrealistic characters such as talking hawks and ten-headed monsters, and unlikely conflicts that feature bloody battles, many of these grand epics display many traditional values that Americans value in modern society. When construing three particular celebrated Indian epics (â€Å"the Mahabharata,† â€Å"the Bhagavad-Gita,† and â€Å"the Ramayana†), readers would easily glean the values and belief system that Ancient Indian society held in high esteem many thousands of years ago. Moreover, by comparing and contrasting respective ideals and principles, similarities between Ancient Indians and Americans would come to surface. The Mahabharata teaches the value of integrity through the story of a deal between a king and a hawk. At a nearby river performing a ritual sacrifice, a king comes across an injured dove trying to escape the clutches of a hawk. He makes a vow to protect the dove and says, â€Å"This bird has come to me for asylum. It is my duty to protect it,† (From the Mahabharata). The hawk rebuts and cites his need for food; consequently, the king cuts a deal and promises to exchange his own flesh to compensate the hawk’s loss: â€Å"You shall have my flesh and nothing less,† (From the Mahabharata). The gods reward him for his integrity and bestow upon him the gift of prosperity. Certainly, our modern society values integrity to a great extent, but the king in this story goes above ordinary ethics and endures pain to protect an innocent life. While most Americans might not s... ... integrity, duty, and honor. The mere prevalence of these regarded values in modern society indicates their utility and tenability. Even though modern Americans might not on a day-to-day basis physically sacrifice themselves, go to battle, or fight a ten headed monster, they share the same principles of integrity, duty and honor with heroes of Ancient Indian Literature toward their perspective towards life.

Local and National Provision for Swimming :: Papers

Local and National Provision for Swimming The sport I have chosen to analyse the Local and National provision for is swimming. I have competed in many "in-club" races and swam against several other clubs, this was through a continuous interest in swimming and sport as a whole. Every popular sport has to be provided for at different levels, from an absolute beginner, to international excellence. At each level, there are different coaching and training procedures, as well as the consideration of the disabled to cater for. This operation is run by the Amateur Swimming Association (A.S.A.), where rules are made official and provision is provided, which coaches and swimmers have to abide by. The A.S.A has a swimmer development program called Swim21. I quote from the website, "Swim21 provides a long overdue nationally recognised club development programme which provides clear pathways which swimmers can progress along. I'm sure the programme will go along way to helping us produce the champions of the future." The quote basically tells us that the A.S.A is very keen to produce talented swimmers into the future and do everything it can to achieve this. Swim21 also applies to disabled swimmers. At grass roots level the most important contributor to the access a young performer has to sport is usually from the school, and this is no different in swimming. As well as this many young children have available to them the opportunity of learning to swim at their local swimming facility. Henceforth, in general, once young swimmers have learned the basics, with a particular enjoyment for the sport, they have the choice to move onto competitive swimming by signing up to a club registered with the A.S.A within their area. The next stage to improving is to enter into a training program, suited for age and experience. Normally within a swimming club, there are teaching groups depending on the experience and skills they have, so that they can therefore train to become better, or train to perfect the skills the need to

Disengagement Theory Essay

This is when a person, usually an older person, withdraws from involvement or when someone’s relationships with other people slowly cut off or change. Older people may withdraw from involvement when they feel they are limited to try and interact with other people. It has been proved that a lot of older people were more involved with life when they were younger however some people disagree and feel there are a large number of people who do not withdraw from society. For example when they retire they may lose contact with a lot of their colleagues or if they or their friends/family have impairments such as hearing or visual impairments it could make it more difficult to interact with each other. Technology may also restrict older people as they may not have internet or phones to be able to interact with their friends and family. Activity Theory This theory highlights the importance of on-going social activity and believes older people should be encouraged to stay involved whilst suggesting that people will be more satisfied with their lives if they remain active as well as ensuring friendships and relationships are intact by interacting with others just the same. It also suggests that someone who remains an active member of society will increase their health and wellbeing and that own-age friendships should be developed. The only criticism of this theory is that some people are more than happy as they are and want to live alone not to mention the fact that not everyone is able to be as active as they would like. As you can see, these theories are completely different in comparison to one and other. One suggests as you get older you will withdraw from society and become unhappy whereas the other suggests you can stay happy and active if you want to and that you just need to remain in contact with different roles in society. If you follow the disengagement theory you are more likely to end up unhappy or lonely as your mental and even physical health may go on to deteriorate through lack of activity or interaction with the outside world and friends or family. On the other hand the activity theory promotes  positivity by encouraging the elderly to communicate and interact with others no matter what their situation. This theory suggests that the more active you are in society, the less chance you have of developing mental health problems such as dementia and that there is a higher chance of prolonging your life and staying healthy. This is because the more you interact with people, the less tim e you will have on your own feeling lonely or depressed as your mind will be busy with positive and happy thoughts instead. There are many different factors that influence ageing and each factor may have a different effect on how the person may age. The main factors would be the personal level of exercise and nutrition in life, health care and education accessibility as well as job roles and finances. Exercise and nutrition, especially from an early age can have a huge impact on how you age later on in life. It is known that premature ageing is caused by a poor diet and little exercise as this causes cell destruction and increases the risk of obesity, diabetes and cancer. A healthy lifestyle can help lower the chances of many illnesses and diseases as well as improving your psychological health, for example the healthier and active you are the more friends and activities you are likely to have to keep you happy and in touch with the world. Health care and education accessibility may also influence the way you age as poorer health care and education facilities may lead to poor health and stress which can affect the way you age and even cause premature ageing Similarly with job roles and finances a higher job role and income can mean a better life with better nutrition, exercise, health care and education helping to lead a more pleasurable life and cause slower ageing. Social isolat ion and bereavement can also take its toll on ageing as the upset and strain can lead you to age a lot quicker and look a lot older than you are due to the body and mind shutting down to try to relieve the stress. The main role for all health and social care workers is to treat and care for individuals whilst respecting their independence and wellbeing whether they are old, young, male, female, disabled etc. Every individual should have the same rights and independence whilst taking into consideration that not everyone will have the same needs and some may need more attention or care than others. Although freedom is important to the individual the health and social care worker must be aware of the extent of the independence to be given to the individual ensuring they are protected against any potential risks or dangers. Independence can be promoted in several different ways, such as: Respecting personal rights and privacy. Giving the individual freedom of choice (where possible). Allowing the individual to carry out actions for their selves, for example letting them wash themselves (where possible). Addressing the individual appropriately and by their preferred name. Using initiative to care for the individual to show genuine care and trust. Involving the individual and their family when making changes to care plans etc. It is important for health and social care workers to address the individual properly as it gives the individual a sense of comfort and trust that the staff will care and respect them. Thinking outside of the box and using initiative when working with the individual will make them feel at ease that you are not just at work to work but at work to care for them as an individual instead of a patient. A great bond and trust between staff and patients is vital. Involving the individual and family with care plans, meal plans and other changes will make them feel valued and that they are in the best hands as it can sometimes be upsetting to both the individual and family when someone they love is reliant on others to care for them. They can feel upset that they are no longer capable of looking after themselves and so the care from the staff can really make a difference. The patients’ freedom of choice is also very important as if the patient was constantly told what to they were to d o without any say they could end up upset or depressed and may even question their existence and feel worthless. Some  choices may not always be appropriate or possible so this means the staff must be trained and taught how to overcome these situations especially against patients that may prove a little difficult. Health and social care workers must work together to give all patients the best care possible. This means regular meetings with different levels of staff in the hierarchy so every staff member is kept in the loop to ensure patients feel valued and cared for, especially those with no family or friends. Regular training sessions may also be required so that the staff is updated regularly on how to approach certain situations with others sharing their experience and knowledge to everyone in the group.

Cherokee Removal Essay

In the early nineteenth century, an infant America was increasing in population and expanding in the South until settlers were faced with the dilemma of the Native Americans. Anglo-Americans had two very distinct stances on how to deal with southern Indian tribes, particularly the Cherokee. One side was eager for land and developed the idea that Indians were both racially and culturally inferior and a hindrance to American progress, while on the other hand, some Americans believed that the Cherokee tribe was a sovereign, independent nation and that moral responsibility required the United States to protect them. Pro-removal Americans rallied behind leaders such as, Andrew Jackson and William Cass. Jackson’s patronizing attitude toward Native Americans was, based on his ideology that Native Americans were children in need of guidance. Jackson also advocated that the removal policy was beneficial to the Indians. Cass believed the Native Americans were unsophisticated and white settlers were racially superior. In his essay, Removal of the Indians, Cass depicts, â€Å"We doubt there is, upon the face of the globe, a more wretched race than the Cherokees, as well as the other southern tribes, present†¦. The Cherokee Removal, pg. 117). † Cass alluded to the underlying racism that piloted the argument for expulsion of the Cherokee. Many white settlers concurred with the belief that Indians were racial inferior and therefore white settlers and Native Americans could not live together. Cass also asserted in the same essay â€Å"A barbarous people, depending for subsistence upon the sanctity and precarious supplies furnished by the chase, cannot live in contact with a civilized community (The Cherokee Removal, pg. 116). Some Americans supported this because they deemed anything different than them as wrong. The pro-removal argument was justified thru the belief that race determined character. For some Anglo-Americans race made Native Americans menial and disposable. Americans against removal united behind the idea that the Native Americans were born on this land and should be left in peace. Jeremiah Evarts under the pen name, William Penn, in A Brief View of the Present Relations between the Government and People of the United States and the Indians within Our  National Limits, said, â€Å"Those Indian tribes and nations, which have remained under their own form of government, upon their own soil, and have never submitted themselves to the government of the whites, have a perfect right to retain their original form of government, or to alter it, according to their own views of convenience and property(The Cherokee Removal, pg. 106). †Evarts’ opposition to removal was based on the fact the Indians were born on the land and therefore it was rightfully theirs. He also pointed out, â€Å"For one hundred and fifty years, innumerable treaties were made between the English colonists and the Indians, upon the basis of the Indians being independent nations, and having a perfect right to their country and their form of government (The Cherokee Removal, pg. 106). † Evarts’ argument was that white settlers legally could not disregard treaties made with Native Americans for hundreds of years. Some Anglo-Americans knew removal of the Cherokee was unconstitutional and to renege on agreements made throughout history was morally incompetent. Catherine Beecher also advocated against Indian removal, writing, â€Å"Nor are we to think of these people only as naked and wandering savages. The various grades of intellect and refinement exist among them as among as (The Cherokee Removal, pg. 112). † Beecher and other Americans opposed removal because they did not believe it was morally righteous to degrade Indians because of race, they considered them people too, and respected the differences in both race and culture. Evarts and Anglo-Americans against removal foresaw the inhumanity of removal, Evarts stated, â€Å"The removal of any nation of Indians from their country by force would be an instance of gross and cruel oppression. (The Cherokee Removal, pg. 107). † Both perspectives on Indian removal had a few commonalities. Some people such as John Knox believed that, â€Å"the central premise of which was that United States Indian policy should make expansion possible without detriment to the Indians (The Cherokee Removal pg. 10). The only consistent agreement however was that the white settlers’ culture and Native American cultures would never successfully co-inhabit. Americans realized that the differences in culture would only continue to cause problems. However the differences was some believed the Indians should be forced west and others believed they should be left in peace. There was an agreement that the Cherokee were uncivilized and to some, even worse not Christian. Again there was another divide on the solution for the primitivism of the Cherokee. Some sought assimilation and of course, removal. In my final analysis, the Cherokee removal argument never reached a consensus, and like most political matters, was won by the most power hungry side. Due to a burgeoning population, racial bigotry, and the lack of centralized government enforcement of the 18th century the Cherokee were forced to leave their homes. The consequence was a forced tumultuous, cross-country walk, where they faced disease, hunger, and fatigue now known as the Trail of Tears. Thousands died, and the removal of the Cherokee had permanent affects on them, as well as all Native Americans.

Positive environment indoors and outdoors Essay

It’s comfortable, interesting, attractive and appropriate for the child or children who use it. For some children it becomes like a second home where they eat and sometimes sleep. A suitable environment for a young baby will be very different from a suitable environment for a four or five year old although some features will be the same. Environments should be attractive and make children feel safe and secure and happy to be there and they should also be places where children can confidently play and learn. Research framework that supports a positive environment for children At the heart of this framework is an approach which recognises the right of all young children to high quality relationships, environments and services which offer a holistic approach to meeting their needs. Such needs should be interpreted broadly and encompass play, learning, social relationships and emotional and physical wellbeing. This approach is important for all children but is of particular benefit in offering effective support to those children and families requiring higher levels of support. Early intervention has relevance to a wide range of social policy but it is particularly relevant in early years, which will often be the earliest and best opportunity to intervene. We have identified 4 principles of early intervention. In short, these are: †¢ we want all to have the same outcomes and the same opportunities; †¢ we identify those at risk of not achieving those outcomes and take steps to prevent that risk materialising; †¢ where the risk has materialised, we take effective action; †¢ we work to help parents, families and communities to develop their own solutions, using accessible, high quality public services as required Outcome 3 how to look after children’s skin, hair and teeth How does a positive environment and routine support children and their families emotional needs? It teaches children how to behave with people in general, so it would help children know how to communicate with their parents and families positively and how to speak to visitors politely. It could also help children to talk to staff about worries they have if the staff are positive and approachable. Having a positive environment also allows parents to talk to the staff and feel included and equal. why is it important for children to have physical and mental time? Basics for a child’s good physical health: Nutritious food Adequate shelter and sleep Exercise Immunizations Healthy living environment Basics for a child’s good mental health: Unconditional love from family Self-confidence and high self-esteem The opportunity to play with other children Encouraging teachers and supportive caretakers Safe and secure surroundings Appropriate guidance and discipline Give children unconditional love. Love, security and acceptance should be at the heart of family life. Children need to know that your love does not depend on his or her accomplishments. Mistakes and/or defeats should be expected and accepted. Confidence grows in a home that is full of unconditional love and affection. Nurture children’s confidence and self-esteem. Praise Them – Encouraging children’s first steps or their ability to learn a new game helps them develop a desire to explore and learn about their surroundings. Allow children to explore and play in a safe area where they cannot get hurt. Assure them by smiling and talking to them often. Be an active participant in their activities. Your attention helps build their self-confidence and self-esteem. Set Realistic Goals – Young children need realistic goals that match their ambitions with their abilities. With your help, older children can choose activities that test their abilities and  increase their self-confidence. Be Honest – Do not hide your failures from your children. It is important for them to know that we all make mistakes. It can be very re-assuring to know that adults are not perfect. Avoid Sarcastic Remarks – If a child loses a game or fails a test, find out how he or she feels about the situation. Children may get discouraged and need a pep talk. Later, when they are ready, talk and offer assurance. Encourage children – To not only strive to do their best, but also to enjoy the process. Trying new activities teaches children about teamwork, self-esteem and new skills. Encourage Children to Play To children, play is just fun. However, playtime is as important to their development as food and good care. Playtime helps children be creative, learn problem-solving skills and learn self-control. Good, hardy play, which includes running and yelling, is not only fun, but helps children to be physically and mentally healthy. Children Need Playmates Sometimes it is important for children to have time with their peers. By playing with others, children discover their strengths and weaknesses, develop a sense of belonging, and learn how to get along with others. Consider finding a good children’s program through neighbors, local community centers, schools, or your local park and recreation department. Parents Can be Great Playmates Join the fun! Playing Monopoly or coloring with a child gives you a great opportunity to share ideas and spend time together in a relaxed setting. Play for Fun  Winning is not as important as being involved and enjoying the activity. One of the most important questions to ask children is â€Å"Did you have fun?’’ not â€Å"Did you win?† In our goal-oriented society, we often acknowledge only success and winning. This attitude can be discouraging and frustrating to children who are learning and experimenting with new activities. It’s more important for children to participate and enjoy themselves Why is it important for children to have quiet and rest time? He body need  time each day to recover from all the activity it has been doing, this is achieved through sleep and rest. There are 3 levels of quiet period. -sleep times are especially required for babies and toddlers, try to make sure that daytime naps are planned for the early afternoon so that the child will still sleep at night. -rest periods are needed for toddlers and pre-school -queit activitites are essential for all age groups as a break between other activities and a chance to recuperate these include things such as story time, doing a quiet activity ort listening to music all of which should use material that is soothing and not stimulating. Older children may enjoy watching tv for a short period of time Explain the basic nutrional requirements of children and young people Plenty of fruit and vegetables – children’s growing bodies require good nutrition and fruit and veg contain a multiple of vitamins, minerals and other healthy compounds. Citrus fruits and strawberries are rich in immunce system boosting vitamin C, carrots are loaded with eye health vitamin A and spinach is a good source if iron. Eating well also decreases the chance of childhood obesitiy and encourages health life style. Plenty of potatoes, bread, rice ,pasta and other starchy foods-starchy foods are a good source of energy and the mains source of a range of nutrients in a child diet, as well as starch they contain fibre, calcium, iron and B vitamins. The protein helps a childs body to grow and repair itself, the fibre helps get rid of waste products, and B vitamins help release energy and help to body to work properly. Some milk and dairy foods-milk and dairy products provide calcium, phosphorous, magenesium and protein which are all essential for health bone growth and development which can prevent and protect children from diseases such as brittle bone disorder later in life. The amounts of calcium in dair products are also beneficial for the development and maitainance of health teeth. Some meat, fish, eggs ,beans and other non-dairy sources of protein- these foods are rich in protein which is needed for lots of functions throughout the body, it is also a good source of vitamin B12 and iron which will help prevent iron deficincy anaemia, which is a common condition found in children and can result in children having little energy and looking pale. Explain the governments guidance on a balanced nutritional diet? The UK’s national food guide, the eatwell plate, defines the government’s advice on a healthy balance diet. The eatwell plate is a visual representation of how different foods contribute towards a healthy balanced diet. The plate model has been tested extensively with consumers and health professionals. The size of the segments for each of the food groups is consistent with government recommendations for a diet that would provide all the nutrients required for a healthy adult or child (over the age of 5). The eatwell plate, based on the 5 food groups, makes healthy eating easier to understand by giving a visual representation of the types and proportions of foods needed for a healthy balanced diet. Choosing a variety of foods from within the 4 main food groups will add to the range of nutrients consumed. This includes: plenty of fruit and vegetables  plenty of bread, rice, potatoes, pasta and other starchy foods some milk and dairy foods  some meat, fish, eggs, beans and other non dairy sources of protein Foods and drinks high in fat and/or sugar are not essential to a healthy diet, and should be consumed only in small amounts.

pangaea essays

pangaea essays Since its early beginnings some 4.6 billion years ago, the earth has been constantly changing its face. Oceans have become deserts and what was once mountainous terrain has found itself submerged in salt water oceans. Underwater volcanoes create new surfaces daily which one day may host a new species of life. It is this metamorphic nature of the earth that interests geologists and paleontologists the world over. What was the appearance of the primitive earth? What changes must have taken place that resulted in the earth we know today? These are some of the questions that scientists have been addressing for years. There has been much speculation about the structural origins of the earth. The most thought-provoking being the idea that at one stage in the earths history all the continents were joined together to form a single mass of land. Francis Bacon first hypothesized the idea in the 1620s, focusing on the parallel shores of South America and Africa. But it wasnt until 1910 when Alfred Wegener scientifically considered the matter of a supercontinent which he called Pangea (Stokes, 1973). Since this time, scientists have argued for and against Wegeners explanation of Pangea. Today skeptics still argue the idea even in the face of overwhelming scientific data. Fossil, geologic and paleomagnetic data clearly validate Wegeners hypothesis- proving the existence of the super continent. Wegener first envisioned that the landmass of Pangea split apart and assumed the current continental positions. The driving force behind this magnificent change was what Wegener called continental drift. As geological evidence to support the idea of continental drift he used the good fit of South America and Africa (Stokes, 1973), which suggests that the two continents used to be joined or were in close proximity to one another. Opponents to continental drift believed that there was no m...

Poverty Research Proposal

Poverty Research Proposal Introduction For a long time, poverty has been perceived to constitute lack or inadequacy of basic needs, including food, clothing, and shelter. The levels by which different societies achieve these three basic essentials vary, and this explains the differences in poverty levels among different societies. Today, America is described to have the highest level of poverty rate compared to other industrialized countries (Garcia, 2011).Advertising We will write a custom research paper sample on Poverty: Research Proposal specifically for you for only $16.05 $11/page Learn More To justify this, the recent and most current statistics from the Census Bureau shows that the level and rate of poverty in USA is increasing, with minority ethnic groups being the most disadvantaged (Dye, 2010). In the past, numerous poverty reduction policies have been formulated and implemented, but their overall impact remains below expectations, as the main beneficiaries are the middle class in expense of the poor (Dye, 2010). Therefore, the situation calls for paradigm shift in policy formulation and implementation. Problem statement In the year 2010, poverty rate in USA stood at 15.1% up from 14.3% recorded in the previous year-2009 (USA Census Bureau, 2011). At the same time, it was noted that poverty rate for the last four years has been increasing at an estimated rate of 2.6%. On overall, in 2010, estimates indicated that about 46.2 million Americans are poor and the rate of poverty increased was observed to affect almost all major ethnic groups in America: Whites, African American, Asians, Hispanic (USA Census Bureau, 2011). Furthermore, the 2010 official statistics indicated the highest rate of poverty the country had experienced and recorded since 1993. Therefore, in order to address this issue of increasing poverty, there is need to conduct an action research that investigates public policy initiatives in USA with regard to poverty, and subsequently propo se the most effective public policy that can be pursued successfully. Significance of the study Poverty remains an issue that ought to be addressed in the American society as a way of achieving the American Dream. Social inclusion goals and objectives postulate that, the well-being of humankind is the essence of stability, peace, and societal development.Advertising Looking for research paper on government?

At the same time, there is need for an effective public policy that comprehensively addresses the issues of poverty in the country. Therefore, this study possesses the ability to create a sound body of knowledge that in turn can be used to create an effective public policy framework. Relevant Literature Review Poverty level in USA is increasing at gradual rate, and the overall impact of this to the society is huge (Garcia, 2011). Addressing poverty has assumed and utilized unilateral public policy models that in turn have led to inadequacy in tackling the issue of poverty. For instance, many of the convectional poverty policies address education, employment, social security, health, economic growth, and tax (Anonymous, 2006). This has been done in separatedness and the result has been construction, formulation, and implementation of skewed and weak poverty reduction models. There is need to establish broad-based understanding of poverty and know that it interplays with other factors and elements simultaneously, hence any attempt to address poverty requires addressing the interplay of accompanying factors. According to Corak (2005), in order to fight poverty, social and physical infrastructure and services can be funded and maintained effectively if the target groups are involved in designing, implementing, and monitoring them, as well as in ensuring accountability of the government o fficials responsible for such policies. Methodology Primary and secondary research methods will be utilized, where primary data will be generated through actual field research techniques, while secondary data will be generated from works already done in the field. Furthermore, reliability and validity of information will be enhanced through use of both quantitative and qualitative techniques. This will see the use of questionnaires, field interviews, poverty program surveys, and in-depth discussion. The aim of this will be to ensure that the public policy to be designed captures the aspect and essence of poverty and subsequent reduction strategies in broad perspective.Advertising We will write a custom research paper sample on Poverty: Research Proposal specifically for you for only $16.05 $11/page Learn More Conclusion Poverty remains a social issue that requires clear strategies of addressing it. Efforts in the past have bore fruits, but given recent tren ds of increasing cases of poverty in the society, there is an urgent need to address poverty comprehensively. It is from this fact that it is recommended that addressing poverty in modern America require an action plan originating from an inclusive and integrated social equity policy strategy.
