Tag-derived Simple Sequence Repeat Markers of Olive

Tag-derived Simple Sequence Repeat Markers of Olive Identification and functional annotation of expressed sequence Tag-Derived Simple Sequence Repeat Markers of olive (Olea europaea) Olive tree (Olea europaea L.) is one of the most important oil producing crops in world, the genetic identification of several genotypes by using molecular markers is the first step in breeding programs. A large number of Olea europaea expressed sequence tags (ESTs) 11,215 were done from the NCBI database and used to search for microsatellites. Our result Explained that 8295 SSRs were present and its percentage of occurrence which about 77.6%,11.84%,8.62%,0.84%,0.77% and 0.29% for Mononucleotide, trinucleotide, dinucleotide, hexanucleotide, pentanucleotide and tetranucleotide respectively. The appearance of the AAG/CTT repeat was highly percentage in trinucleotide and percentage of AG/CT was highly in dinucleotide repeats. By using flanking region of SSRs repeat we designed 1,801 EST-SSR primer pairs. The result obtained from Functional annotation of olive EST sequences containing SSRs indicated that 81% of these sequence having homology with known proteins, while 1.55% was homologou s to hypothetical or unknown proteins and the 17.37% sequences did not possess homology with any known proteins. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation revealed that EST containing SSRs were implicated in diverse biological process include cellular and metabolic process, while in molecular function includes catalytic activity, binding and enzyme regulator activity. A total of 93 different pathways were significant matches in the KEGG database, which divided onto Carbohydrate metabolism such as glycolysis/gluconeogenesis pathway and the Energy metabolism such as Carbon fixation in photosynthetic organism pathway, also this included 11 different pathways from Lipid metabolism such as Fatty acid biosynthesis pathway. We isolate a genomic DNA from 9 olive cultivars and tested with 25 random selected primer pairs for amplification and polymorphism detection. All tested primers, exhibited successfully amplified and detected polymorphism. Olive tree (Olea europaea L.) is one of the most superannuated and important long lived fruit species in Mediterranean [1], its diploid species (2n = 2x = 46), and the genome size range between 2.90 pg/2C and 3.07 pg/2C, with 1C = 1,400 1,500 Mbp [2]. Olea europaea is one of the first domesticated crops from Oleaceae family, and it cultivated for table olives and edible oil [3], a long history of olive cultivation in the Middle East was descriptions by archaeology and botanists [4]. The olive cultivars are high of number that more than 1200 cultivars [5], also the accessions are available in a large numbers in olive producing countries, that occurrence a problems for germplasm preservation and it management [6]. The genetic identification and characterizing of several genotypes by using molecular markers is the first step in breeding programs [7], and by increased rate of mutation in microsatellites repeats that show a highly level of length polymorphism [8]. With the improvement and increasing of DNA sequencing technology, sequencing of expressed gene are used to obtain a large collection of EST which are isolated from a specific tissue and stage on organism [3]. Recent EST-SSR studies have reported that the EST is uses a source of SSRs and that reveal highly polymorphism [9]. EST sequences Available in public database and by using bioinformatics tools can determine and development of SSR markers in that EST sequences [10]. In olive that can be allow to development of new functional marker and use it in molecular breeding [11]. Also it can use as useful tools for gene and marker discovery, gene mapping and functional comparative studies. EST-SSRs recently reported in several plant species, such as Musa [12], Finger Millet [13], Jatropha Curcas [14], Pineapple [15], Celery [16], Lettuce [17], Barley [18], Radish [19], Citrus [20], Watermelon [21], Sugarcane [22], grapes [23], Cereal species [24] and bread wheat [25]. A large number of EST sequences in olive are available on database it can be a useful resource to develop gene based markers. The aim of this study was to use bioinformatics tools to develop and identify a new genic marker EST-SSR in Olive, to compare the frequency and distribution of different repeat types in genic sequences. Also determine the localization of these primers in different pathways in plant, to use it as tools to differences between the olive cultivars. The Source of Sequence, screening and primer designing of microsatellites. EST database used a source of olive EST sequences from NCBI (http://www.ncbi.nlm.nih.gov). A total of 11,215 ESTs sequences of Olea europaea are available and used in this study. Identification of SSRs by using the perl script MISA (MIcroSAtellite identification tool; http://pgrc.ipk-gatersleben.de/misa/).The criteria used to determine SSR repeat were: mononucleotide ≠¥ 10, dinucleotide ≠¥ 6, trinucleotide, tetranucleotide, pentanucleotide, and hexanucleotide ≠¥ 5, and the maximal number of bases interrupting two SSRs in a compound microsatellite are 100 bp. The flanking region of SSR motifs used to design SSR primers by using primer3_core [26]. The parameters used were: optimum length of primer 20 nucleotides, optimum annealing temperature (Tm) of 58 °C, expected amplified products size of 100-500 bp and optimum G/C content 50 %. Validation of designed primer For primer validation, we designed 25 EST-SSR primers and test these primers on 9 olive cultivars. Total genomic DNA was extracted from olive leaves using Plant Genomic DNA Kit (QiGen). PCR amplification was conducted in 25  µ l reactions containing 50 ng of template DNA, 2.5 mM MgCl2, 5  µ l 5X PCR buffer, 0.5 mM each primer, 0.5 U Taq DNA polymerase, and 2.5 mM dNTPs. The PCR cycling profile was 94 °C for 5 min, 35 cycles at 94 °C for 45 s, the optimum annealing temperature for each primer pair shown on (Table S1) for 50 s, 72 °C for 45 s, and a final extension at 72 °C for 10 min. The quality of the PCR product was checked by mixing it with an equal volume of loading buffer and then visualizing the band on a 1.5% agarose gel in TBE buffer at 100 W for 120 min. Identification of EST-SSRs Putative Function annotation The putative function annotation of EST sequences contains SSR performed by used Blast2go program [27] to BLAST against a reference database. Also blast2go program are containing many features such as Gene Ontology (GO), Enzyme Commission (EC), and KEGG annotation. Distribution of various repeat type in olive Our result referred to 4,088 EST sequences about 36.45% from 11,215 of Olea europaea EST sequences as containing 8,295 various motif SSRs that Due to the EST sequences maybe contain more than one SSR motif (Table 1), and this number based on the criteria we used it to identify SSR motifs in the EST sequence. The investigation of different types of SSR repeats in our result showed that the highest percentage of appearance mononucleotide repeats were 77.64%, followed by trinucleotide 11.84%, dinucleotide 8.62%, hexanucleotide 0.84%, pentanucleotide 0.77% and tetranucleotide 0.29% (Fig. 1). The higher abundant of trinucleotide in coding regions were consistent with the previous studies in eukaryotic genomes [28, 31]. In mononucleotide A/T repeats 88.8% were higher than the G/C 11.2% motifs, and these results were proportionate with SSRs analysis of chloroplast SSRs on Olea species [29] and with SSRs analysis of major cereal organelle genome [28]. GA motifs were representing 55% from dinucleotide motifs in olive EST sequences. According to previously studies from foxtail millet [31], barley, maize, rice, sorghum and wheat [30], GA motifs were the most abundant motifs in these crops. AG/CT and GA/TC motifs were the most frequent respectively and CG motifs the lowest frequencies were found in olive, this case reported in the distribution of microsatellites on three different plant families that Brassicaceae, Solanaceae and Poaceae [32]. Dinucleotide motif can represent to multiple codons that depending on the reading frame and can translate into different amino acids such as, AG/CT motif can represent AGA, GAG, CUC and UCU codons in mRNA and translate into the amino acids Glu, Arg, Leu and Ala respe ctively, Ala and Leu were present in protein at higher frequencies, hence the higher incidence of GA, CT motifs in the EST sequences [33]. This could be one of the reasons why GA, CT motifs are present at such highly appearance in EST collections [34], dinucleotide repeats that located on coding regions are more sensitive to any change such as any addition or deletion because that causes a frame shifts and will give different amino acids [35]. As for trinucleotide TCT, TTC were the most common repeat motif in olive EST (Table 2), While AAG/CTT motifs were the most common in chloroplast of Olea species SSRs [29], however, in other crops such as barley, maize, rice, sorghum and wheat CCG or AAC were the most common trinucleotide repeat [30]. Our results revealed that tetranucleotide motifs AATC, CTTT are the most common; however the most common in Olea species SSRs chloroplast were AAAG, CTTT [29]. Pentanucleotide and hexanucleotide AAAAT and GAAAAA respectively are the most common repeat motif in our results while [29] found AATCC was the most common on pentanucleotide in Olea species SSRs chloroplast and hexanucleotide was not found. Design and validate of EST-SSR In this study, we designed 1,801 PCR primer pairs from the 8295 SSR motifs of Olea europaea EST, The designed primers were referred as Oe-ESSR_xxxx, where Oe-ESSR referred to Olea europaea EST SSR, xxxx was referred the number of EST-SSR from 1-1801 and that different of the previously SSR primers designed from chloroplast sequences of Olea species [29]. This primers were listed in the (Table S1), and provide with all information related it such as Primer name, GenInfo Identifier gi number of EST sequence, Repeat type, Repeat Sequence, Length of Repeat, Repeat start on sequence, Repeat end on sequence, Forward and Reveres Primer, Tm ( °C), Length of Primer (bp), product Length (bp), sequence of EST, Sequence Description, gene ontology, Enzyme code and Enzyme Name. We use a sample of 25 primers randomly from these 1,801 EST-SSR primers to validate it by using a genomic DNA isolated from 9 olive cultivars. All tested primers, exhibited successfully amplified and detected polymorphism (Fig. 2). Putative Function annotation of EST-SSRs The putative function annotation of the EST sequences containing SSR performed by used Blast2go program [27]. According to the Blast2go result, 81% from EST sequence as homology with known proteins, while hypothetical or unknown proteins were 1.55%, and 17.37% of this EST sequences did not homology with any known proteins. The gene ontology of olive EST sequences containing SSRs using Blast2GO revealed that in the biological processes, the highly appearance of SSR were involved in cellular processes, metabolic, response to stimulus, biological regulation and developmental process, while Signaling, rhythmic processes and growth had the lowest SSR contents among these EST. The molecular function category includes catalytic activity and binding, while cell membrane and organelle were assigned in the cellular component category (Fig. 3). The Similar results were found on functional annotation of the citrus and date palm EST sequences containing SSRs [20, 36]. Our results agreement with t he similar results obtained in [20] which suggested that genes were involved in protein metabolism and biosynthesis were well conserved in plants. Functional classification by KEGG pathway analyses The KEGG Pathway analysis is useful tool to understand the molecular interaction and biological functions [37]. Our study exhibited a total of 93 different pathways include 253 enzymes target by 381 EST-SSR primers were significant matches in the KEGG database (Table S2), this data can Visualization by using circos software [38] (fig. 4). The higher occurrence of SSR on pathways indicated a good potential for using these molecular markers to targeting the enzyme related to the trait subjected in our study. This EST sequences contain SSR were categorized into metabolism, as well as its subcategories, including lipid metabolism (Table 3), carbohydrate metabolism, energy metabolism, amino acid metabolism, nucleotide metabolism and metabolism of cofactors and vitamins. In details, the mapping result can further investigated against the glycolysis/gluconeogenesis (Fig. 5), Oxidative phosphorylation (Fig. 6) and Fatty acid degradation (Fig. 7) pathways as an example of Carbohydrate metabolism, Energy metabolism and Lipid metabolism respectively. Conclusion SSR markers are very important because it is co-dominant, highly polymorphic and can generate from functional regions of the genome. EST-SSR technique have the potential to generate phenotypically linked functional markers and a useful tool can use on genetic diversity, marker assisted selection and genome mapping in olive. This study exhibited the functional categorization of olive EST sequences containing SSR revealed that these ESTs representing in genes with cellular component, biological process and molecular function. This EST-SSR primers also providing with useful information to understand the biological functions and genes interactions according to the localization of this primers in different pathways related to possible phenotypic differences between the olive cultivars.

An Analysis of Night by Elie Wiesel Essay

â€Å"One day as I was looking in a mirror, I didn’t recognize myself†¦I then decided that since everything changes—even the face in the mirror changes—someone must speak about that change. Someone must speak about the former and that someone is I. I shall not speak about all the other things but I should speak, at least, about that face and that mirror and that change. That’s when I knew that I was going to write.† Elie Wiesel in Conversation with Elie Wiesel â€Å"I owe them my roots and memory. I am duty-bound to serve as their emissary, transmitting the history of their disappearance, even if it disturbs, even if it brings pain. Not to do so would be to betray them, and thus myself.† Elie Wiesel, â€Å"Why I Write,† in Confronting the Holocaust: The Impact of Elie Wiesel One of the primary themes or messages Elie Wiesel said he has tried to deliver with Night is that all human beings have the responsibility to share with others how their past experiences have changed their identity and how those experiences affect others. Wiesel believes that, in order to understand the true impact of the Holocaust, survivors like himself must serve as messengers to current and future generations by â€Å"bearing witness† to the events of the Holocaust and by explaining how those events changed each individual’s identity.

The role of government in fostering intermodal transport innovation

Freight transportation systems are very important all over the world and are considered to be very significant to the world for regional and local economies (Konings & H. Nijkamp, 2008). The author has explained that using 1994 gross national product numbers freight transportation made 6. 3 per cent of total expenditure (Knoning & H.Nijkamp, 2008).Freight transportation represents a percentage of total expenditures 38. 52 per cent of the total. Here in the United States freight transportation system has become very important of global network, which has increase capacity and demand for the needs of customers that are placed on freight services.There have been past studies and concerns about environmental and health issues, for these reasons, yes, I do agree with the author and that he did provide several reasons â€Å" to implement proactive policies to foster intermodal transport innovation and ultimately, enhance the competitive edge of the American economy, foster the role of fre ight transportation as an agent of economic development and efficiency of the freight system, and to reduce the negative environmental and health externalities, and congestion, produced by freight transportation activity† (Knoning & H.Nijkamp, 2008).The author also explained and shows that the absence of intermodal innovation initiatives in the United States and that the analysis may provide proof and insights into how to tackle the problem of defining, implementing intermodal innovation initiatives† (page, 304). It is very clear that that the author has also explains that â€Å"well-documented American case provides insights into how best to overcome the challenge associated with defining policies, programmes to foster intermodal innovation (page, 304).The analysis does provide supporting information that assess the role of the government. The United States is known to be a major the head of transportation research and innovation. The author explained that â€Å"it wa s not easy to identify a consistent or coherent focus on the systemic challenges of freight transportation† due to part of which could be found in the institutional diversity and durability of American transportation finance planning and operations.The twentieth century, research efforts by the government and universities and private industries has grown and so have diversity (page, 305). The major agency that identifies and sponsor or conduct freight transportation research in the United States that highlights their influence role. (1) National Science Foundation (NSF)-and expanding the partnership with USDOT, based on successful model of public-private research partnership in the semiconductor industry.(2) Federal Highway Administration (FHWA) largest best funded of USDOT, responsible for managing the Federal Aid Highway program. (3) Federal Railroad Administration (FRA) conducts research in the area of safety. Bur of Transportation Statistics (BTS) is the America’s p rimary repository of data on all aspects of mobility, and in cooperation with the US Census Bureau, BTS is conducts a Commodity Flow Survey (CFS) every five years.The Department of Transportation (DOT) supports and participates in applied transportation research aimed at for improving maintenance or enhancing their operations and funds freight research projects that is through local universities and the federally sponsored University Transportation Centers (UTCs), which are projects that focus on either specific operational issues or freight transportation modeling to support statewide planning efforts.National Cooperative Highway Research Program (NCHRP), administered by the Transportation Research Board under the guidance of the Standing Committee on Research of the American Association of State Highway and Transportation Officials (AASHTO). All can be found in additional locations for American transportation research, Metropolitan Planning Organizations (MPOs), by law focus on tr ansportation and land use issues in the United States urbanized areas, and diverse geography from across the MPO jurisdictions, which only some of them would identify freight movement.The Intermodal Surface Transportation Efficiency Act, supports exploration of the freight transportation opportunities has enabled intermodal planning and project development which is to become a central focus of the federal and state transportation agencies work according to the author on (pages, 308, 309). The author did show the main challenges of implementing a research programme that could stimulate intermodal innovations in freight transportation.The author stated that† the size and complexity of the American freight system poses a challenge that the implementation of freight research programme, which conflicting objectives of different freight modes are a reflection of competing with each other. The competition includes all modes and across the whole geography of the country† (page, 315).Singapore for example, the Netherlands, has a close association between the success or failure of a particular freight enterprise, meaning that the Port of Singapore and Port of Rotterdam and the economic development of the country, shows the importance of freight transportation and intermodal innovation which shows more cooperative working environment between the private industry and the government(page, 316).So in other words the planning horizons of the system’s operators, which are part of the private sector that keeps day-today operations of time horizons, short. This makes the public agencies responsible for planning, financing and implementing transportation projects. For as planning cycles is complex decision making and to implementing procedures is short term-within two years, medium terms two to five years, long term 10-20-50 year planning horizon.This planning horizon complicates the process by trying to define goals with transportation agencies and freight in dustry. When trying to advance the innovations from freight transportation research, disparity needs to take things into account, meaning that the research community and the freight industry should join and work together to consider freight issues for the nation’s economy. The freight industry leaders need to play a very critical role by raising the level of awareness with transportation research, education and training (page, 318).The analysis did show the focus on the American case conclusions, recommendation, and identified challenges that are related to an institutional setting and features that are related to the American freight transportation system, and related to the government agencies. There needs to be larger steps towards using research for intermodal transport innovation. The public and private policy people need to come together to engage to implement efforts for change.

Social Darwinism and the Holocaust Essays

Social Darwinism and the Holocaust Essays Social Darwinism and the Holocaust Essay Social Darwinism and the Holocaust Essay Social Darwinism is an ideology found commonly within the late nineteenth century. It was inspired from Darwinism and is the result of natural selection. Social Darwinism is a theory rooted in the ability to apply the laws of nature to a society and its people and is often associated with the popular notion of â€Å"survival of the fittest. † However, it is often used to justify social and political policies that discriminate against a certain type of people. What role did Social Darwinism play in the unfolding of the Holocaust? Social Darwinism played a role in the Holocaust through the Theory of Natural Selection and the lead versus follow principle; both allowed Hitler to believe the Aryans as the â€Å"Master† race and the need to exterminate all other peoples, in particular the Jews. It is important to examine and distinguish the differences between Darwinism and Social Darwinism when applying the Theory of Natural Selection to Hitler and the Nazi ideology. Secondly, the concept of human behaviour plays a key role in the unfolding of the holocaust through the Lead versus Follow principle. Darwinism, the philosophy of Charles Darwin, is a biological philosophy that proposes that there is a process of natural selection that seeks to advance superior species. This Theory of Natural Selection acts to slowly accumulate small advancements in genetic mutations. The members of the species that fail to accumulate these small advancements would eventually be subject to extinction and thus leaving the superior members to prosper. Social Darwinism follows the same premises. Social Darwinism’s Theory of Natural Selection states that one group of people are better than all others and thereby the lesser of the peoples are left to die out on their own or there is justification in their execution. The goal is to continuously advance the best members of society to form the best societies possible. Social Darwinism’s Theory of Natural Selection continues to develop the idea that some peoples had advanced more than others and thereby the continuous extinction of more primitive members of society is a natural process and is justifiable to help along this process by forced extinction. Social Darwinists seek to promote the idea of the best societies possible; the most intelligent people, the most beautiful, the healthiest. It was Social Darwinism that had an influential role in the Holocaust through specifically the Theory of Natural Selection. The Theory of Natural Selection as expressed by Social Darwinists is a theory that attempts to protect a selective group of people above all others. To protect these selected people certain restrictions applied. The people deemed to be below the superiors are limited in who they partner with, there is a restriction placed on people so they cannot dirty the gene pool and mix amongst the superior peoples. The superior peoples are given special status and are isolated from anyone who might contaminate the group. [1] Those superior members of society came to be the Aryans. For Hitler this race of people was deemed to be pure and in some way better than all others. Aryans were characterized by blonde hair and blue eyes as opposed to the Jews who had dark hair and darker coloured eyes. According to Hitler and Himmler, a top SS leader, there were many conflicts that Hitler must face; the entire Jewish population, Marxism, freemasonry, and churches. The Jews were thought to be the driving force and â€Å"the origin of all the negatives†[2] that would cause dilemmas for Hitler. It wasn’t a question for Hitler and Himmler if the Jews would hold out; it was a question of merely how long they would last. [3] For Hitler the annihilation of the Jewish population would solve many of his problems and he thought his ruthlessness in their utter destruction would be highly appreciated amongst his peers. Hitler thought that by eliminating the Jews specifically he would be ridding Europe of the bad seeds that were holding back the master Aryan race. According to Hitler ridding Europe of all those who failed to conform to the Aryan standards would be doing the world a favour. By eradicating themselves of the Jews then the Aryans could form a better, more pure and more complete society that would be responsible for future advancements in the European world. [4] To further make the distinction between the superior Aryan people and the unimportant Jewish people new measures began to take place. Jew could no longer practice certain careers; they could no longer keep a business, they were required to clearly identify themselves as Jews, their passports were stamped with a â€Å"J†, and they had to alter their names adding ‘Israel’ to the male name and ‘Sara’ to the female name. [5] Slowly Hitler attempted to execute all the European peoples except the Aryan race. This process can be described as a forced process of selection wherein Hitler chose who would further society and who was not fit to live. A form of The Theory of Natural Selection is at play here yet instead of the selection being a natural process the decisions were made primarily by Hitler who believed the Jewish population was the root of his negative problems. It wasn’t only the Jewish population that seemed to pose a problem for Hitler. Hitler wanted to amass all peoples against the Jews so their extermination wasn’t based solely on his own justification. Hitler wanted to turn people against all those who weren’t part of the Aryan Master Race to a point where they would blindly follow his principles without questioning them. The Lead versus Follow principle is a principle that explains why, through a group mindset, people are more likely to follow a leader because of pressure rather than actual like thinking. This principle is characterized by group think and a single person’s inability to rationally draw conclusions that differ from those expressed by the represented leader. In terms of the Holocaust, Hitler is the leader and the German people are his followers. When characterizing the German people as a group it is easier to see the Germans as a whole system rather than the individuals within it. By doing this Hitler can control a larger portion of the population at once without worrying about individual rebellion because the pressures from peers would crush any objections. [6] This is beneficial to Hitler’s plan to exterminate the Jews because with the coerced support of the German people he was free to act as he wished without fear. Social Darwinism plays a role here through the idea that if there was no public rebellion then they too believed that the Jews needed to be executed to preserve the sanctity of their superior race. Whether or not this was actually the mindset of the German people was not important, what was important was that Hitler was able to alter the culture of the people. Culture is a group phenomenon which has the ability to remain unchanged for generations yet when faced with a single change has the power to adapt into a completely new and complex system. It makes individuals dependent on the society until it stabilizes. [7] Hitler realized this and through his dictatorship he altered the mindset of the German people to a point where they themselves began to believe in their own superiority. The idea of superiority over another is a premise of Social Darwinism, a premise that the people Hitler deemed Aryan began to believe. In conclusion, Social Darwinism played a role in the Holocaust through the Theory of Natural Selection and the Lead versus Follow principle. Both recognized Hitler’s choices behind the eradication of mainly the Jewish population. Social Darwinism is a concept that can be used to examine the ideas behind Hitler’s dictatorship over the German population and his need to glorify the Aryan race and exterminate the Jewish one.

The Construction of a Geneticist The construction of a geneticist is a person that follows a difficult path of education, preparation, and hard work. Geneticists along with all branches of Genetic Engineering have grown in numbers and importance over the last hundred years. Geneticists have accomplished things that Isaac Asimov and authors like him only dreamed about. What was science fiction then is science fact now, the cycle continues through this day. (Facklam 16) The genetic field will continue to grow until every aspect of life is perfect, but that will take quite a while. Career Opportunities in Genetics are everywhere within the biological community. They may work in colleges and universities, research institutions, medical institution, and commercial enterprises of many kinds. Every work environment is unique, and categorizes overlap-but certain general trends exist. (Career Opportunities in Genetics 9) Genetic Engineering has a long past and an even longer future, however, to enter the field a person must have a strong background in sciences and intensive training. Despite the controversy of Genetics, Courtney Sailes of the Genentech Inc. has accomplished such training. He is working in the biochemistry division and has an important impact people across the world. Gregor Mendel is known as the father of Modern Genetics, however he was not the start of the long chain of genetic engineers. (Microsoft Encarta 98) Genetic engineers can be traced back to 6000 BC when Yeast was used to make beer by Sumerians and Babylonians. Before that the domestication of animals was the most complex example of genetic engineering. Todays geneticists still work with animals and plants, however, instead of just studying them, they can create them. Geneticists also try to perfect and alter deficiencies to help solve problems in todays world. Geneticists creation of bigger fruit, vegetables and vaccinations help people live everyday. Genetic Engineering may one day eliminate horrible genetic defects. (Facklam 79) Genetic Engineering is a science that can alter the ways in which we live, but not with out social and legal problems to solve as we go along. (Facklam sleeve) The discovery of the structure of DNA resulted in an explosion of research in molecular biology and genetics, paving the way for the biotechnology revolution. Genetic engineering became a reality when a man-made gene was used to manufacture a human protein in bacteria for the first time. Biotech companies and universities were off to the races, and the world will never be the same again. (Biotechnology Timeline 1977- Present) Accomplishments done in part of genetic engineering have made the earth a better and safer place to live. Hybridization of rice and wheat has increased food output by more than 100%. (Encarta 98) Geneticist across the world are attempting to stop the spread of deadly cells strains, if there is a virus or bacteria there is a cure and a way to stop it. The vaccination of polio, the cure for leprosy, and small pox all are possible due to the minds and wills of genetic engineers. On July 25, 1979, Louise Brown became the worlds first test-tube-baby, hailed by many as a biological breakthrough and condemned by other as a way for man to control and manipulate life. (Facklam 87) The cloning of Dolly, the lamb, and other animals allows scientist to research cures for illness with little deviation in subjects. Almost all breakthroughs in the medical research field are directly related to genetic engineering. Geneticist play an important role in everything around us, they give us more than just better creations they give us a better understanding of life as we know it (C.O. in G. 14), Geneticist is just a general title given to several occupations. Each specific occupation consists of its own environment, but share many common traits.

Student motivation or engagement in high school urban students Research Paper - 1

Student motivation or engagement in high school urban students - Research Paper Example In this paper, I have research the problem of student motivation. I wanted to know what additional instructional strategies engage students as well as any incentive system that would influence their participation. In this study, I included different rewards both intrinsic and extrinsic in trying to improve participation in preparation for an upcoming professional certification exam. Keeping the students engaged with their learning would bring success and value to their education. Subsequently, this could be behavior modification for the classroom. In a school’s computer lab, students are posting on their Facebook pages and listening to music. No this is not a study or the library, but a computer lab in an urban setting during classroom instruction. How do we enhance student’s motivation toward learning? With so many obstacles present in the urban school districts such as poverty, lack of parental involvement, high drop rates, substance abuse and gang involvement, it is a struggle to get students to recognize the need for education. The level of student engagement is directly connecting to teaching practices (Adkins-Coleman, 2010). As a teacher, you are responsible for classroom management and the instruction that you provide to your students. If you can engage your students in the classroom and motivate them to learn; this will assist in behavior management and move the students toward academic success. With behavior being an obstacle in a classroom, how are new teachers prepared to work in an urban environment? To prepare future teachers more adequately for urban schools, teacher educators need to provide the opportunity for them to learn from teachers who successfully facilitate engagement (Adkins-Coleman, 2010). Schools need to find appropriate mentors for new teachers as well as provide professional development to educational staff with new instructional strategies for the classroom. The level of student engagement is

Compare and Contrast the Culture, Mission, and Vision of Profit and Research Paper

Compare and Contrast the Culture, Mission, and Vision of Profit and Nonprofit Organizations - Research Paper Example In cash basis accounting method financial information is recorded according to real time cash flow. Again under the accrual basis system, revenue is recorded when it is earned rather that when the payment is received. Profitable organizations maintain their financial records by following a standard accounting system but this system may not be followed by a non profitable organization as their nature of work is different than the profitable organization. In this regard this can be said that both types of organization will never follow similar type of accounting method for the business activities. This report will compare and contrast the accounting methods which are applied in profitable and non profitable organization. The accountants of one profitable and one non profitable organization are providing the information about the accounting standard followed by those companies in their interview session. Here the profitable organization is Apple Inc which is an American multinational co mpany which manufactures computer software, consumer electronics, personal computers and online services. The example of non profitable organization is Virginia Community Capital, Inc. It is a nonprofit banking entity and community development financial institution. This organization provides innovative investment solutions and loan for economic developmental projects and affordable housing in the Commonwealth of Virginia. Huge differences can be observed in case of accounting system for nonprofit and profitable organization. In case of profitable organization this can be said that this kind of business has started for providing benefits to the business owners and shareholders of the company. For this reason profit is one of the major goals of these businesses and company has to pay tax on the amount of profit. But in case nonprofit organization this can be
