Short Story and Pride Essay Example

Short Story and Pride Essay Pride is a wonderful thing, but too much pride may blind someone to the inevitable future they create. Pride is great it gives people self confidence and makes them happy. The more pride someone has the more they accept themselves. Excessive pride can leave people to poor choices that cannot be reversed. In the short story The Cask of Amontillado by Edgar Allan Poe, Fortunate is a prideful man with a great life; however, he lets his pride blind him to his inevitable faith. Fortunate prided himself a little too much on his connoisseurship of wine believing himself the best. (209) Mentors having much pride in himself as well ought revenge on Fortunate for insulting him, and uses Fortunate pride against him by threatening to use another wine tester. Fortunate falls for this trick by letting pride overcome himself. In the short story The Scarlet Ibis by James Hurst brothers pride gets in the way of his caring for his little brother.

Research a current issue in relation to the topic - Assignment Example this reason, the paper will dwell on the solution and the effects of the lack of legal privilege towards the male and female along with recognizing the prevailing stereotype of the issue on hand. It has been proven that college students who encountered abuse are more comfortable in dealing with their experience with their peers rather than with professionals. In this manner, it is more acceptable to these students to deal with their experience with an informal conversation with their peers (Balk 179). According to the report written by Caroline Kitchener, she cited that it has been reported that most of the universities in the United States are already offering â€Å"peer-to-peer sexual assault counselling programme.† This programme is beneficial for students, as well as for the institution. However, most of these undergraduate peer counsellors receive at most 24 hours training. This is supported by the study of Salovey and D’Andrea (264) that shows most of the peer counsellors receive inadequate training materials and programs prior to being peer counsellors. The interview of the peer counsellors suggested that there was inappropriate and synchronized training model for the peer counsellors. The problem with this inadequate training is that the peer counsellors do not have the legal privilege to make their conversations with the involved individuals confidential. Therefore, the university peer counsellors must undergo trainings which are approved by the state in order for them to practice legal privilege in terms of confidentiality. Legal privilege is given to them in order to protect the involved individuals when forced to disclose their conversations (Anderson). The lack of assurance that the conversation between the peer counsellor and the involved individual often times restricts the involved individual in being honest with the counsellor. For both men and women, they will be hesitant in sharing their vulnerable and fragile moments and feelings towards the

Case study - Essay Example This needs a consent and disclosure form that should be separate from all job application form. The list of present and past addresses is the foundation for a systematic background check. Knowing where the person has lived is crucial for deciding where to search for criminal records and looking for time gaps as well, and mismatches of location compared to the information given by the applicant. An individual’s social security number (SSN) gets  given between their first job (victor, 2010). Hence, an SSN validation one can know if the applicant has a particular SSN one gave or the applicant is lying. The best searches for criminal background get carried out at person counties since there is no centralized entity to control every criminal record. One of the reason is the likelihood of getting criminal record is high in an individual’s present county residence because several crimes take place near their work or home. County searches are useful since misdemeanors and felonies normally get prosecuted at county courts court, and their results may not be reported to the state. Victor (2010) states, Background checks should get offered before employment. This is due to the sensitivity of the information in the applicant reports and particular records. To avoid getting information that would discriminate against the applicant, they are free to know where the origin of information used against them. Also, they should consent before the employer obtains a credit report. How to carry out background checks online: research and choose a company to conduct background checks on the applicants. Register for the website. Then request background checks. Once one clears registration, start requesting for background checks from the company by putting pertinent data for the applicant as prompted (Victor, 2010). It is risky since one

Analysis of Early Roman civilization Assignment Example | Topics and Well Written Essays - 250 words

Analysis of Early Roman civilization - Assignment Example For instance, the practicality of the Roman civilization is evident from the many roads they built as well as their strong belief in faith and patriotism(Forsythe, 30). Besides, early Roman civilization stressed on morals and characters and held women in high regards unlike other civilizations like the Greek. Education was still information with the focus on teaching children about Roman religion and ideas. Early forms of education included memorization of the Roman’s Twelve Tables (Forsythe, 32). Home education would also account for civilization of early Rome as the emperor built schools because it was expanding. Education during early Roman civilization was practical based, and this explains the Romans tremendous contribution in engineering and law. Conversely, early civilization ideologies planted a bad culture of spectatorship among the Romans as they focused more on professionalism. The civilization bred a materialistic culture where Romans focused more on wealth acquisition and luxury living. However, it is the luxurious nature of the civilization that would mark the decline of the emperor because barbaric groups gathered with intention of getting the rich life of the emperor without fighting invaders (Forsythe,

Optically Active Polymers

Optically Active Polymers Optically active polymers play very important role in our modern society. The speciality of optically active polymers are known with its various characteristics as occurred naturally in mimicry. The present review describes the monomers and synthesis of optically active polymers from its helicity, internal compounds nature, dendronization, copolymerization, side chromophoric groups, chiral, metal complex and stereo-specific behaviour. The various properties like nonlinear optical properties of azo-polymers, thermal analysis, chiroptical properties, vapochromic behaviour, absorption and emission properties, thermosensitivity, chiral separation, fabrication and photochromic property are explained with details. This review is expected to be of interesting and useful to the researchers and industry personnel who are actively engaged in research on optically active polymers for versatile applications. Optically active materials are those which can able to rotate the plane of polarization of a beam of transmitted plane-polarized light containing unequal amounts of corresponding enantiomers. The optical activity originates from the presence of chiral elements in a polymer such as chiral centres or chiral axes due to long-range conformational order in a macromolecule. In fact, most naturally occurring macromolecules possess the ability to organize to more complex high structure rather than single one and manifest their functions. Optically active polymers are related to problems of the charged and reactive polymers, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized. Chiral compounds are optically active and essential for life such as proteins, polysaccharides, nucleic acids, etc. and chirality is most important for existence. About 97% drugs are formed from natural sources, 2% are recemates and only 1% is achiral, in looking of chirality of nearly 800 drugs. Optically active polymers today have also become of great interest and thus play an important role in molecular arrangement and assembly, which is critical for optoelectronics super molecular structure [1-4]. The synthetic optically active polymers may also play important role like mimicry of naturally occurring polymers and that’s why the extensive studies are required on their synthesis, conformations and properties. Various kinds of optically active polymers e.g., fro m its helicity, internal compounds nature, dendronization, copolymerization, side chromophoric groups, chiral, metal complex and stereo-specific behaviour are reported, however, those are not placed in a systematic manner. In the present review an effort has been made to collect most of those works in one place for better understanding in the subject with detailed explanation of properties like nonlinear optical properties of azo-polymers, thermal analysis, chiroptical properties, vapochromic behaviour, absorption and emission properties, thermosensitivity, chiral separation, fabrication and photochromism. -Classification of optically active polymers Optically active polymers are divided into three types: Biopolymers as obtained from nature. Polymers prepared by almost completely isotactic polymerization by modification of naturally occurring polymer backbones such as polysaccharides. Synthetic polymers as per the requirement with proper tailoring of functional groups. -Speciality of optically active polymer Optical properties of polymers are not so different of other substances, excepting those characteristics related to the chain dimension and structure or conformational changes. Optically active polymers have found interesting applications because of their specific properties. The optical properties of these materials lie at the basis of many applications, for example in chromatographic methods for enantiomeric separations or creating complex optical devices. The dispersion of the specific rotation offers information regarding the conformational changes or Cotton effect. Optically active polymers characteristics as follows: Optically active polymers with configurational chirality: the optical activity is given by the presence of an asymmetric carbon atom in the backbone or in the side chain of the monomer; Optically active polymers with conformational chirality: the optical activity is related to the conformational changes; Optically active polymers with both configurational and conformational chirality: the optical activity is given by macromolecular asymmetry and by the presence of the asymmetrical centers. -Monomers of optically active polymers Some biological polymers are composed of a variety of different but structurally related monomer residues; for example, polynucleotides such as DNA are composed of a variety of nucleotide subunits. The solid-state structures of polystyrene – poly(Z-L-lysine) block copolymers were examined with respect to the polymer architecture and the secondary structure of the polypeptide using circular dichroism, quantitative small and wide-angle X-ray scattering, and electron microscopy [5]. Synthesis of optically active polymers The optically active compounds are synthesized by highly efficient methodologies and catalysts. The various synthetic approaches for optically active polymers are described below: Helical polymer: Helicity is one of the subtlest aspects of polymer chain where the polymer chain spiral structure along the chain axis acts like a spring. Helical polymers are frequently occurring in nature in single, double or triple helices form in genes, proteins, DNA, collagen, enzymes, and polypeptides. The helical conformations increase the stability of the natural polypeptides. Preparation of artificial helical polymers is a great challenge to the researchers. So far, only limited success has been achieved in constructing microscale particles using helical polymers, despite the great number of analogous microparticles created from vinyl polymers and even from other conjugated polymers like poly(thiophene), poly(phenylene ethynylene), and poly(fluorene) and polyacetylenes. Meckings et al has performed extensive investigations on preparing nanoparticles from polyacetylenes, which have shown interesting potential in inkjet printing. Later on, various group of researchers have successfully prepared both nano and microparticles consisting of optically active helical substituted polyacetylenes [6]. Such nano- and microarchitectures demonstrated remarkable optical activity and significant potential applications ranging from asymmetric catalysis, chiral recognition/resolution, and enantiomer-selective crystallization to enantio-selective release [7-9]. Synthetic helical polymers may be classified as either static or dynamic helical polymers, depending on the inversion barrier of the helical conformation [10-11]. Static helical polymers have a relatively high energy barrier for helix inversion and are stable in solution, while dynamic helical polymers have a relatively low energy barrier for helix inversion and exist as a mixture of right- and left handed helical domains that are separated by rarely occurring helix reversals. Even a slight incorporation of optically active repeat units can shift the equilibrium to excess one-handed helicity. The chiral recognition properties of biopolymers with skilled emulating of synthetic helical polymers are currently a focus of much interest. Enantioseparation, catalysis, and sensing are among the more promising applications of molecular recognition based on responsive three-dimensional intramolecular or intermolecular superchiral structures. Optically active conjugated polymers represent an attractive class of chiral macromolecules adaptable to this purpose because their chiral behaviour can be augmented by nonlinear electrically conductive or optical properties arising from conjugation along the backbone. The first example of optically active polycarbazoles, poly[N-(R)- or (S)-3,7-dimethyloctyl-3,6-carbazole]s (R- or S-PDOC) were synthesized in 60-70% yield using modified nickel coupling method [12]. Helical polymers are easily denaturalized by certain physical factors e.g. heat, ultraviolet irradiation, and high pressure and by other chemical factors such as organic solvents. Various helical polymers have been synthesized, which include polyisocyanates, polyisocyanides, polychloral, polymethacrylates, polysilanes, polythiophenes, poly(p-phenylene)s, poly(1-methylpropargyl-ester)s, poly(phenylacetylene)s and poly(-unsaturated ketone) [13-19] (Fig. 1). Other polymers are whose optical activity is main chain or side chain chirality dependent e.g. amino-acid-based polymers are nontoxic, biocompatible and biodegradable. Optically Active Polymers Optically Active Polymers Introduction Optically active polymers are related to problems of the charged and reactive polymers, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized. Most of the naturally occurring molecules/macromolecules, such as nucleic acids, proteins, and polysaccharides are chiral and optically active. Chirality is essential for life. This situation can be very obviously seen if  we look at the chirality of nearly 800 drugs (about 97%) derived from natural sources. Only 2% are racemates and only 1% is achiral. Synthetic optically active polymers are of great interests, since they might mimic the fascinating functions of naturally occurring polymers, leading extensive studies being conducted on their synthesis, conformations and functions. In fact, most naturally occurring macromolecules possess the ability to organize to more complex high structure rather than single one and manifest their functions. Optical activity is a ph ysical spectral property of chiral matter caused by asymmetric configuration, confirmations and structures which have no plane and no centre of symmetry and consequently have two mirror image enantiomeric forms of inverse optical rotation. The recemic mixture of chiral enantiomers is optically inactive. The great majority of natural molecules contain chiral centres and are optically active. This is the case because living systems and their extracts as enzymes are able to produce completely stereoselective asymmetrical synthesis or transformations. This led Pasteur to say that ‘life is asymmetrical’ at the molecular level. The majority of food and drug molecules of physiological activity are chiral [1]. Xi et al. [2-8] investigated about chirality of optically active compounds. Optically active polymers today have also become of great interest owing to their chiral structure which may play an important role in molecular arrangement and assembly, which is critical for optoelectronics super molecular structure [9-12]. Chiral polymers with helical chain backbone have received increasing attention due to their helicity generating from secondary interactions such as hydrogen bonds and van der Waals forces. These chiral helical polymers undergo conformational change as well as helical reversal easily. The concept of the optically active aromatic chromophore as ‘conformational probe’ in isotactic polymers can be further extended by the use of optically active monomers [13]. Optically active polymers have exhibited a number of interesting properties in several highly specialized areas such as chromatographic resolution of steroregular [14], chiral [15-16], asymmetric catalysis and phase of the separation of racemic mixtures [17], thermosensitivity [18], synthesis molecular receptors and chiral liquid crystals for ferroelectric and nonlinear optical applications [20]. In the last year [52], Angiolini and co-workers have synthesized and investigated methacrylic polymers bearing in the side chain the chiral cyclic (S)-3- hydroxypyrrolidine moiety interposed between the main chain and the trans azoaromatic chromophore, substituted or not in the 4’ position by an electron withdrawing group. In these materials, the presence of a rigid chiral moiety of oneprevailing absolute configuration favours the establishment of a chiral conformation of one prevailing helical handedness, at least within chain segments of the macromolecules, which can be observed by circular dichroism (CD). The simultaneous presence of the azoaromatic and chiral functionalities allows the polymers to display both the properties typical of dissymmetric systems (optical activity, exciton splitting of dichroic absorptions), as well as the features typical of photochromic materials (photorefractivity, photoresponsiveness, NLO properties). Recently, highly efficient methodologies and catalysts have been developed to synthesize various kinds of optically active compounds. Some of them can be applied to chiral polymer synthesis and in a few syntheses for optically active polymers; chiral monomer polymerization has essential advantages in applicability of monomer, apart from both asymmetric polymerization of achiral or prochiral monomers and enantioselective polymerization of a recemic monomer mixture. Optically active chiral polymers are not only fundamentally interesting, due to the rich and complex architecture of macromolecular chirality as compared to that of small molecules, but also technologically important because their unique chiral arrays give rise to a number of potential, and in some cases commercially implemented. Classification of Optically active polymers: Optically active polymers are divided into three types: Biopolymers: Biopolymers are the main type of biomaterials. According to their degradation properties, biopolymers can be further classified into biodegradable and non-biodegradable biopolymers. Many implants, such as bone substitution materials, some bone fixing materials, and dental materials, should possess long term stable performance in the body. Recently biopolymers acts as developments in bone tissue engineering, vascular tissue engineering, nerve tissue engineering, genitourinary tissue engineering, regenerative medicine, gene therapy, and controlled drug delivery have promoted the need of new properties of biomaterials with biodegradability. Biologically derived and synthetic biodegradable biopolymers have attracted considerable attention [21]. Polymers prepared by almost completely isotactic polymerization by modification of naturally occurring polymer backbones such as polysaccharides. Synthetic polymers: Polymers synthesized from low molecular weight compounds are called synthetic polymers, e.g., polyethylene, PVC, nylon and terylene [7]. This polymer is also divided into three types: (a) Addition polymers: Addition polymers are including vinyl, aldehyde, isocyanide and acetylene polymers that were prepared via addition polymerization reaction such as poly(acryl amide)s, polyolephynes, polystyrene derivatives, polyazulenes, poly(vinyl ether)s, polymethacrylate, polymethacryloylamine, polychloral, polyisocyanides, polyisocyanates, polyacethylene and polyethers [22–32]. (b) Condensation polymers: Condensation polymerization continues to receive intense academic and industrial attention for the preparation of polymeric materials used in a vast array of applications [28]. One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. (c) Cross-linked gels: One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. Why optically active polymers are important? or Speciality of optically active polymer Optical properties of polymers are not so different of other substances, excepting those characteristics related to the chain dimension and structure or conformational changes. Optically active polymers have found interesting applications because of their specific properties. The optical properties of these materials lie at the basis of many applications, for example in chromatographic methods for enantiomeric separations or creating complex optical devices. The dispersion of the specific rotation offers information regarding the conformational changes or Cotton effect. Optically active polymers characteristics as follows: -Optically active polymers with configurational chirality: the optical activity is given by the presence of an asymmetric carbon atom in the backbone or in the side chain of the monomer; Optically active polymers with conformational chirality: the optical activity is related to the conformational changes; Optically active polymers with both configurational and conformational chirality: the optical activity is given by macromolecular asymmetry and by the presence of the asymmetrical centers. Monomers of Optically active polymers Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. This is the case, for example, in the polymerization of PET polyester. The monomers are terephthalic acid (HOOC-C6H4-COOH) and ethylene glycol (HO-CH2-CH2-OH) but the repeating unit is -OC-C6H4-COO-CH2-CH2-O-, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. The identity of the monomer residues (repeat units) comprising a polymer is its first and most important attribute. Polymer nomenclature is generally based upon the type of monomer residues comprising the polymer. Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat units are known as copolymers. Poly(styrene) is composed only of styrene monomer residues, and is therefore classified as a homopolymer. Ethylene-vinyl acetate, on the other hand, contains more than one variety of repeat units and is thus a copolymer. Some biological polymers are composed of a variety of different but structurally related monomer residues; for example, polynucleotides such as DNA are composed of a variety of nucleotide subunits. The solid-state structures of polystyrene – poly(Z-L-lysine) block copolymers were examined with respect to the polymer architecture and the secondary structure of the polypeptide using circular dic hroism, quantitative small- and wide-angle X-ray scattering, and electron microscopy [33]. Synthesis of optically active polymers Much of the attention in chiral polymers results from the potential of these materials for several specialized utilizations that are chiral matrices for asymmetric synthesis, chiral stationary phases for the separation of racemic mixtures, synthetic molecular receptors and chiral liquid crystals for ferroelectric and nonlinear optical applications. Presently optically active compounds are synthesized by highly efficient methodologies and catalysts. In a few synthetic approaches for optically active polymers, chiral monomer polymerization has essential advantages in applicability of monomer, apart from both asymmetric polymerization of achiral or prochiral monomers and enantioselective polymerization of a racemic monomer mixture [17].

Marketing Essay -- Papers

Marketing Different Companies have different methods of selling their products, some companies decide to launch an item and wait for the results of the sales. Another method of selling a product is to research the market in which it is to be sold. There are various ways of conducting some market research, much depends on the item you wish to sell, the time you may have to research and the amount of money that is available. People who are expected to be consumers may be approached in order to recognise their needs, this may be done through questionnaires verbally by post or by phone once their needs are recognised it will be clearer what to provide for them. Research into the companies' product may provide information into potential competition and pricing the product. Price is of obvious importance for maximum sales and maximum profit. Researching the market may suggest that a sample should be circulated in order to address and amend any issues for example if it is an edible product the taste and smell must be considered if it is an electrical product the functions may be considered is it user friendly or practical or too complicated the right product with the wrong design will not sell and cold turn a potential profit into a potential loss. Studying peoples buying patterns will unveil ideas as to where this product should be sold, where people are more likely to buy them the consumer will have to be targeted and the product strategically planned in order to sell e.g. Haagen Dazs Good market research and prompt recognition and coherence will allow the producers to adopt relevant selling strategies and the ability to ... ...oduce enough in June 1994 and therefore decided not to use any advertising promotions. This may have been avoided if primary research had been done earlier to see what the demands of the consumers were, and the forecast of the weather. The product proved to be successful and ultimately that is what produces profits. Walls chose to conduct little primary research it may be that it was not required as Solero was a success, but it may also suggest that Walls missed out on profits of one month in an exceptionally hot summer because of lack of primary research Also arguably, Walls set out to repeat the success of Magnum in the indulgence sector but according to the impulse-positioning map Solero is purchased as refreshment and not indulgence does this mean that there is still room for a product in the indulgence sector?
