Smith, Susan H. "Extraction of Additives from Polystyrene and Subsequent Analysis." Thesis, Virginia Tech, 1998. http://hdl.handle.net/10919/36774.
Full textAbstract:
The extraction of fifteen (15) polymer additives with supercritical carbon dioxide which are used as antioxidants, uv stabilizers, process lubes, flame retardants and antistats from eight formulations of polystyrene is demonstrated and compared to traditional dissolution/precipitation extractions. The purpose of the study was twofold: 1) the development of a high performance liquid chromatography (HPLC) method(s) for the additives and 2) the determination of the viability of supercritical fluid extraction (SFE) for the additives from polystyrene.
Separation of some of the additives was achieved using reversed phase liquid chromatography. Nine of the additives were assayed in this manner while, the remaining six additives could not be assayed using reversed phase liquid chromatography. In order to develop an extraction method for the additives, the effects of static extraction time, CO2 density, and temperature were first investigated. These preliminary extractions revealed that a static extraction period which afforded an opportunity for the polymer to swell combined with a high CO2 density and extraction temperature above the glass transition (Tg) yielded quantitative recoveries of the additives. Triplicate extractions of the various polystyrene formulations matched additive recoveries obtained by the traditional dissolution/precipitation method.Master of Science

Nixon, James. "Analysis of the stretch blow moulding process and subsequent simulation development." Thesis, Queen's University Belfast, 2015. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.677457.
Full textAbstract:
Injection stretch blow moulding (ISBM) is the most common processing method of producing thin-walled poly (ethylene) terephthalate (PET) containers. With numerous processing parameters and complex deformation, there is still a certain amount of expert knowledge required to successfully convert a PET preform into a useable bottle, capable of passing rigorous post-process testing. The purpose of this work is to develop an accurate simulation of the bottle forming procedure through extensive examination of the input parameters and how they affect the preform deformation and bottle characteristics. By removing the bottle mould, a free-stretch-blow analysis was performed over a large process window. This procedure utilised the digital image correlation (DIC) method with a patterned preform heated using an oil bath. A corresponding simulation was constructed using ABAQUS/Explicit FE solver and a constitutive viscoelastic user material subroutine. A comparison between the experimental and predicted values of internal cavity pressure, stretch-rod force and surface strain was performed resulting in reduced accuracy at low flow rate, sequential-type deformations. Free-stretch-blow trials also highlighted the need for adequate preform storage as increased moisture content affects the deformation behaviour. Reapplying the bottle mould and using the same process parameters revealed that the simulation had difficulties in predicted accurate bottle thickness, particularly at higher flow rate. An insufficient contact friction model was concluded and more insight into the heat transfer and back pressure between the polymer and mould was required. Results from the simulation also demonstrated that the previously assumed incompressible behaviour of PET during bottle formation is incorrect. A novel method of measuring strain levels in all three directions was devised to reveal that deformation mode greatly affects the value of Poisson's ratio. Insight into the ISBM process and development of the simulation has been advanced through this work and key areas of further improvement have been revealed.

Ness, James William. "A developmental analysis of the effects of retrieval on subsequent recall of prose." Diss., Virginia Polytechnic Institute and State University, 1988. http://hdl.handle.net/10919/77827.
Full textAbstract:
This study was designed to investigate the effects of retrieval on memory for prose in second-graders and adults. Specifically, this study assessed the effects of retrieving an interleaved story in canonical form on the subsequent retrieval of that story in its originally presented interleaved form. Subjects were randomly assigned to one of five conditions. The critical comparisons were between the invalidation condition and its control condition. In the invalidation condition, the experimenter said that the initial instructions to recall the story were incorrect and that the subjects should now recall the story exactly as presented. Subjects in the control condition were asked to recall the story exactly as presented after recalling the story canonically.
The results indicated that the nature of recall was greatly influenced by the demands of the retrieval task. Second-graders and adults made more theme-irrelevant elaborations in the invalidation condition than in the control condition. Second-graders' recall protocol was more congruent with the most recent recall instructions when their former recall instructions were invalidated than in the control condition. In contrast, adults' recall protocol was congruent with the most recent recall instructions whether or not their initial recall instructions were invalidated. Congruence was measured by episode clustering (ARC) and by input-output Spearman Rank Order Correlation.
These findings suggest that conditions at retrieval and not at encoding appear to determine what form recall will take. Further, the findings of this study suggest that second-graders are more likely to internalize experimenter provided retrieval plans than are adults and are more likely to abandon these retrieval plans when provided with negative evidence for their internalized plan. Schmidt and Schmidt (in preparation) have recently argued that recall is influenced by a retrieval plan and that one of the sources through which a retrieval plan can be generated is through the retrieval context. They also argue that the retrieval context should have its most powerful impact when limited or inappropriate retrieval plans are available to the subject. The differences between second-graders and adults reported here serve to support this view.Ph. D.

Coffey, Brandon Wade. "Age Differences in the Impact of Emotional Cues on Subsequent Target Detection." TopSCHOLAR®, 2015. http://digitalcommons.wku.edu/theses/1508.
Full textAbstract:
Emotional cues within the environment capture our attention and influence how we perceive our surroundings. Past research has shown that emotional cues presented before the detection of a perceptual gap can actually impair the perception of elementary visual features (e.g., the lack of detail creating a spatial gap) while simultaneously improving the perception of fast temporal features of vision (e.g., the rapid onset, offset, and re-emergence of a stimulus). This effect has been attributed to amygdalar enhancements of visual inputs conveying emotional features along magnocellular channels. The current study compared participants’ ability to detect spatial and temporal gaps in simple stimuli (a Landolt Circle) after first being exposed to a facial cue in the periphery. The study was an attempt to replicate past research using younger adult samples while also extending these findings to an older adult sample. Unlike younger adults, older adults generally display an attentional bias toward positive instead of negative emotional facial expressions. It is not clear if this positivity bias is strictly driven by cognitive control processes or if there is a change in the human visual system with age that reduces the amplification of negative emotive expressions by the amygdala. The current study used psychophysical data to determine if the rapid presentation of an emotional cue and subsequent perceptual target to older adults leads to the same benefit to temporal vision evinced by younger adults or if amygdalocortical enhancements to perception degrade with age. The current study was only able to partly replicate findings from past research. The negative facial cues that were presented in the periphery did not lead to an enhancement in temporal gap detection for the younger adult sample nor a reduction in spatial gap detection. In fact, the opposite was found. Younger adults’ spatial gap detection benefited from the negative emotional cues. The negative and neutral emotional cues had no effect on the older adult sample. The older adults’ performance on both gap detection tasks was not impacted by the emotional cues

Full textAbstract:
Abstract
This study deals with optimal design of cantilevered fluid-conveying pipes. The aim is to maximize the critical flow speed of the fluid by means of additional masses, supporting springs or dampers along the length of the pipe.
The optimization problem was formulated by modelling the pipe by FEM, using Euler-Bernoulli beam elements. The locations of the additional masses, springs and dampers and the properties of these elements (mass, spring constant and damping constant) were chosen as design parameters. The maximization problem for the critical fluid flow speed was solved by the sequential quadratic programming (SQP) technique.
In addition to the presentation of the optimal values obtained for the design parameters, some aspects of the sensitiveness of the systems to variations in these parameters and the robustness of the optimum designs with respect to the stability of the system are studied.
Although a considerable increase in the critical flow velocity of the fluid can be achieved in the example cases studied here, a marked sensitivity of the system to the location and properties of the additional elements in the optimum designs was observed. Also, the margin with respect to stability seems to be relatively small in some of the optimum designs considered.
Non-linear numerical analysis confirmed the findings of the linear analysis with respect to the sensitivity of the optimum designs to the properties of the additional elements and revealed a very rich post-critical dynamic behaviour in the optimized structures.

Full textAbstract:
The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.

Full textAbstract:
This study examines the relationship between the surveyed intentions of young men to join the military and their actual enlistment behavior. Of specific concern, is how knowledge of this relationship might benefit the United States Marine Corps in achieving cost-effective management of recruiting resources. A review of selected literature examines the use of an intentions variable in manpower forecasting models as well as some of the major research efforts involving surveyed intentions. The analysis uses a longitudinal data base, created by merging responses from the 1976-83 Youth Attitude Tracking Study (YATS) with Defense Manpower Data Center (DMDC) cohort files, to examine the connection between an individual's self-stated propensity to enlist and his subsequent behavior. The analysis also attempts to describe selected characteristics of individuals who joined the military -- including demographic variables, quality indicators, and measures of performance -- on the basis of their YATS response. There was no conclusive evidence of major differences in the characteristics of enlistees who were initially positive or negative toward joining the military. However, the results of the study do suggest that different combinations of intentions and demographic characteristics may lead to different patterns of enlistment behavior.

Full textAbstract:
Thesis (MComm)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Investment styles and more particularly the relative outperformance of certain styles under differing market conditions have been widely researched. Furthermore, investment professionals are constantly on the lookout for factors that could possibly be indicative of the subsequent outperformance of certain investment styles. With the value-growth phenomenon at the centre of this debate, there is an attempt in this study to shed some light on this anomaly from a purely South African perspective. Using monthly data for the period 1991 to 2011, and calculating price-to-book value (P/B) ratios for all the stocks included in the FTSE/JSE All-Share Index, the methodology employed by The Brandes Institute (2009A), based on work of Lakonishok, Shleifer and Vishny (1994), will be utilised in this study in order to determine whether the relative outperformance of value stocks over growth stocks can be anticipated in advance. Stocks were ranked monthly on the basis of their relative P/B ratios and subsequently four new portfolios were created each month, with the growth portfolio consisting of the highest 25% P/B ratio stocks and the value portfolio capturing the lowest 25% P/B ratio stocks. After portfolio creation, quartile-by-quartile performance was tracked over the following five years. The relative performance of the value versus growth portfolio was compared to the valuation difference multiple, calculated as the median P/B ratio of the growth portfolio divided by the median P/B ratio of the value portfolio, to determine if a relationship existed between valuation disparities and the subsequent relative performance of value and growth stocks. The all-cap (FTSE/JSE All-Share Index) segment was further divided into large-cap (FTSE/JSE Top-40 Index), mid-cap (FTSE/JSE Mid-cap Index) and small-cap (FTSE/JSE Small-cap Index) segments in order to determine if a consistent relationship could be identified within different market capitalisation sectors of the market. A significant relationship was found between the valuation difference multiple and subsequent performance of value and growth stocks in all segments of the JSE Mainboard. Historically, the higher the valuation difference multiple, the higher the subsequent outperformance of value stocks over the subsequent five-year period, as compared to growth stocks. This was found to be significant within the FTSE/JSE All-Share Index, the FTS/JSE Top-40 Index, the FTSE/JSE Mid-Cap Index and the FTSE/JSE Small-Cap Index. An exception to the above findings was the post-2002 period within the FTSE/JSE Top-40 Index. During this period it was not possible to identify a relationship between the valuation difference multiple and subsequent value stock outperformance.
AFRIKAANSE OPSOMMING: Verskillende beleggingstyle en meer spesifiek, die relatiewe uitprestering van sekere style onder verskillende mark omstandighede, is wyd nagevors oor die afgelope paar dekades. Professionele beleggers is ook gedurig op die uitkyk vir moontlike faktore wat die uitprestering van sekere beleggingstyle vooraf kan aandui. Met die waarde-groei verskynsel sentraal in hierdie debat, is die doelwit in hierdie studie om die waarde-groei verskynsel te ondersoek vanuit 'n eg Suid-Afrikaanse mark perspektief. Deur maandelikse data vir die periode 1991 tot 2011 te gebruik en daaropvolgende prys-tot-boekwaarde (P/B) verhoudings te bereken vir al die aandele wat deel was van die FTSE/JSE Alle-Aandele Indeks, sal daar in hierdie studie die metodologie van 'The Brandes Institute' (2009A) in die Verenigde State van Amerika, gebaseer op die werk van Lakonsihok, Shleifer en Vishny (1994), toegepas word om te probeer bepaal of die relatiewe uitprestering van waarde aandele oor groei aandele vooraf voorspel kan word. Aandele is maandeliks ingedeel op die basis van hul onderskeie P/B verhoudings. Deur hierdie proses is daar maandeliks vier nuwe portefeuljes geskep, met die groei portefeulje wat die hoogste 25% van P/B verhouding aandele bevat het en die waarde portefeulje wat die laagste 25% van P/B verhouding aandele verteenwoordig. Prestasie beoordeling van die nuut geskepde portefeuljes was die volgende stap in die navorsingsproses waar kwartiel-tot-kwartiel prestasie beoordeling oor die daaropvolgende vyf-jaar periode na portefeulje ontstaan, plaasgevind het. Die relatiewe prestasie van die waarde en groei portefeuljes is vergelyk met die waardasie pariteit maatstaf, wat bereken is as die mediaan P/B verhouding van die groei portefeulje gedeel deur die mediaan P/B verhouding van die waarde portefeulje. Hierdie vergelyking is gebruik om te bepaal of 'n verhouding tussen die onderskeie waardasies van groei en waarde aandele en daaropvolgende prestasie bestaan. Die alle aandele segment is verder ook opgedeel in drie onderskeie indekse om te bepaal of 'n verwantskap binne al die verskillende markkapitalisasie sektore bestaan. Die grootste markkapitalisasie aandele is verteenwording deur die FTSE/JSE Top-40 Indeks; die medium markkapitalisasie aandele deur die FTSE/JSE Mid-Cap Indeks; en die kleinste markkapitalisasie aandele wat deel vorm van die FTSE/JSE Alle-Aandele Indeks is verteenwoording deur die FTSE/JSE Small-Cap Indeks. 'n Beduidende verwantskap is gevind tussen die waardasie pariteit maatstaf en daaropvolgende vyf-jaar prestasie van waarde en groei aandele. Histories hoe hoër die waardasie pariteit maatstaf, hoe groter die relatiewe uitprestering van waarde aandele oor die daaropvolgende vyf-jaar periode. Hierdie verskynsel is beduidend gevind vanuit 'n FTSE/JSE All-Share Indeks, FTSE/JSE Top-40 Indeks, FTSE/JSE Mid-Cap Indeks en FTSE/JSE Small-Cap Indeks perspektief. 'n Uitsondering was die FTSE/JSE Top-40 Indeks vir die periode na 2002, waar dit nie moontlik was om 'n beduidende verwantskap te identifiseer nie.

Full textAbstract:
Drug usage, both of a recreational or pharmaceutical nature, is common, however the abuse of such substances is an international problem. In the Western cape, South Africa, the burden of drug-related fatalities is high compared to the rest of the country. The provincial Forensic Pathology Service may encounter cases where drug-related fatalities are unclear whether death was accidental or suicidal, or drug toxicity is inconsistent with the medical/social history. This may be due to genetic alterations with drug metabolism and it has been suggested that genetic analyses may be the next step in these cases. However, toxicology results from the National Forensic Chemistry Laboratory in the Western Cape may be delayed by months to years, meaning that upon interpretation of toxicology results, there is no chance to obtain another blood sample from the deceased individual for genetic analysis. It was therefore important to determine the suitability of blood samples collected and handled in toxicology environments for subsequent genetic tests. Previously, blood samples from 30 post-mortem cases were collected into two red-top (no additives), two grey-top (sodium fluoride/potassium oxalate) and one purple-top (EDTA) tubes. Samples from one red-top and one grey-top tube underwent toxicological analysis, followed by DNA analysis, while the remaining tubes (controls) underwent DNA analysis immediately. All samples were then stored for approximately one year, prior to this study. The DNA analysis was repeated on all blood samples (n = 150) and results were assessed in terms of storage time and tube type. DNA was not significantly degraded in any of the samples; however, DNA from red-top tubes had significantly lower concentrations compared to that from grey-top tubes (p < 0.001), regardless of whether the sample had undergone toxicological analysis. The very low yields of DNA from red-top tubes posed substantial challenges for PCR-based analysis, resulting in poor quality Sanger sequencing results. Some DNA from grey-top tubes, passed the quality assessments and hence further work is required to provide an informed decision on which tube type is better suited for genetic analyses.

Full textAbstract:
Marine Protected Areas (MPAs) are implemented to address a variety of management concerns, including conservation and restoration of fisheries, but few studies assess how MPAs affect regional fishing patterns. Previous research suggests effort will intensify at MPA edges, but few datasets include sufficient pre-implementation data to quantify how MPAs alter fishing effort. We used recreational fisheries data collected by scientific observers aboard Commercial Passenger Fishing Vessels that target nearshore fish species, primarily rockfish. We assessed shifts in the spatial distribution of fishing effort over a 10-year period that includes pre- and post-implementation observations of the California MPA network along the Central Coast. We visually depict fine-scale annual fishing pressure, calculate total regional effort, and identify changing hot spots of fishing activity. While we found no evidence for “fishing the line”, MPA implementation was associated with changes in regional fishing patterns, including contraction of fishing effort away from the northern extent of the region and increased effort intensity in some pre-MPA fishing hotspots. Fishing effort redistribution should be considered in future management decisions regarding California’s MPA network.

Full textAbstract:
This study examines the interface between Kenyan politics and ethnicity. More specifically it examines why ethnicity is at the core of Kenyan politics. Although this study discusses how colonialism influenced the ethnicisation of African politics, it focuses more on the era of post-colonial politics. The objective of the study is to investigate how post-colonial Kenyan leaders have shaped the content of Kenyan politics. This study explores ethnic conflicts in Kenya, more especially the 2008 conflict. In order to provide a clear framework for the analysis of Kenyan society, Zambian politics and its social dynamics were also examined in this study. In terms of political development and other variables, one could describe Zambia as Kenya’s peer. It is, therefore, an ideal country against which to evaluate Kenya. In terms research methodology, this study has taken a descriptive and an explanatory approach. Thematic and content analysis has also been employed as data analysis methods. This study has established that the manner in which Kenyan politics are organised is centred on ethnicity. The study found that Kenya’s unique political and social components have predisposed Kenya to ethnic conflicts. For example, a political future within Kenyan political parties and in public office is heavily influenced by one’s ethnicity. Ethnicity also plays a role in the nature of political coalitions. As a solution to the Kenyan problem, this author has recommended that Kenya’s politics (and political campaigns) be based on issues related to the development of Kenyan society, rather than ethnicity. Those in public office should also elevate national identity above ethnic identity.

Full textAbstract:
Traditionally, it has been widely accepted that current reinvestments leads to future growth, and hence that there exists a negative relationship between dividend payout ratios and subsequent earnings growth at both the company and market level. Surprisingly, more recent research found a positive relationship between these two variables, rationalised in terms of management signalling positive future prospects through higher dividend payouts. Following the methodology developed by Arnott and Asness (2003), this study conducted an analysis in to which hypothesis is supported at the market level (proxied by the All Share Index) in South Africa, and how these findings compared to international market level findings. Furthermore, the findings were analysed within the context of the political and economic conditions unique to the South African market over the 1960-2014 study period. The results indicated a negative relationship between the payout ratio and subsequent earnings growth from 1960 to 2014. When the time period was subdivided into periods before and after 1994 (a year considered to be a structural break in South African political-economic history), a positive relationship was found from 1960-1994, while a negative relationship was found from 1994-2014. The possible explanations for this contradiction were investigated. For the counterintuitive pre-1994 result, several literature-based tests were conducted in order to eliminate possible explanations other than the link between payout ratio and earnings growth. Firstly, the tests were repeated for three and five year earnings growth periods. With regard to the five year period, although the coefficient for the payout ratio was positive from 1960-2014, the results were statistically insignificant. The subdivided regression periods, 1960-1994 and 1994-2014, also indicated less significant results. For the three year earnings growth period, the regression test generated positive coefficients for the payout ratio variable for all the time periods, with both sub-periods being statistically significant. The difference between the ten and three year subsequent earnings growth findings may have been as a result of South Africa companies making better long-term (ten year) than short-term (three year) investments during that time period. In addition, the possible impact of share repurchases, earnings yields as earnings growth predictors (i.e. the market valuation impact), and the possible role of mean reversion were all either considered, or statistically tested. Although the former two played no role, it was found that mean reversion was a statistically stronger predictor of future earnings growth on the index level than payout ratio. As the above result s differ not only from most (but not all) international studies, and also from the one company-level study previously conducted for South Africa, these differences were further investigated. In terms of the latter, it was found that the most likely reason for the discrepancy was that the previous researcher, who confined her study to JSE-listed industrial stocks, used nominal earnings growth data as opposed to real growth data. It is argued that this is an incorrect approach. Nonetheless, given that means reversion is as good, if not a better, predictor of earnings growth at the market level in South Africa, the traditional hypothesis that a higher payout ratio implies reduced future earnings growth, cannot be ruled out for the JSE.

Por meio de situações problemas, foi proposta uma investigação do controle de estímulos presente em tatos metafóricos (fera e vírus) como antecedentes verbais descritos pelo experimentador. Houve distintas condições experimentais para cada tato metafórico que exigiu a emissão de respostas verbais subsequentes de cada participante, após a leitura de um texto informativo. As respostas verbais subsequentes envolveram indicar entre alternativas a melhor para a resolução de problemas fictícios entre medidas preventivas e corretivas e informar a uma pessoa desconhecida sobre o texto informativo lido. O experimento foi arranjado, sob a hipótese de que os participantes tenderiam para medidas preventivas, se lessem o texto informativo com o tato metafórico da violência comparada a um vírus, ou para medidas corretivas, se lessem o texto informativo com o tato metafórico da violência comparada a uma fera. Os participantes, individualmente, foram convidados a realizar o mesmo protocolo de tarefas solicitadas na Linha de Base e na Condição Experimental. Este protocolo envolveu quatro tarefas, a saber (1) leitura de um texto informativo (2) escolha de alternativa preventiva ou corretiva para solução de problemas sociais, como fome na Linha de Base e violência na Condição Experimental, (3) indicação de trecho de controle para realização da tarefa anterior e (4) emissão de comportamento intraverbal, ou seja, contar sobre o texto informativo lido na primeira tarefa para uma pessoa desconhecida, que veria virtualmente. Na Condição Experimental, os participantes de cada grupo tiveram contato com informação apresentada por meio de metáforas distintas (grupo G-I e grupo G-II), sem metáfora (grupo G-III) e com estímulos arbitrários (palavra sem sentidos) comparados a metáforas distintas (grupo G-IV e grupo GV). Em todas as condições experimentais, houve avaliação do comportamento do participante como falante e ouvinte de seu próprio comportamento verbal. O experimento trouxe dados instigantes entre os grupos experimentais, visto que os participantes do grupo (a) G-I replicaram os dados de estudos anteriores em apenas 20% das respostas dos participantes, (b) G-II mantiveram controle verbal em 80% das respostas verbais subsequentes, ao assinalarem por medidas preventivas diante da metáfora vírus, (c) G-III mostrou uma prevalência dos participantes por medidas preventivas, visto que todos responderam por esta alternativa, (d) G-IV replicaram os dados de pesquisas anteriores mantendo uma relação entre o tato metafórico fera para 60% respostas verbais subsequentes com medidas corretivas, enquanto que (e) G-V estabeleceram o controle verbal metafórico sobre 100% das respostas verbais subsequentes com medidas preventivas. Na discussão de dados, são tecidas considerações acerca do desempenho dos participantes por grupo ressaltando (1) história de vida e história experimental, (2) contextos atuais e culturais presentes na vida dos participantes, (3) estabelecimento do controle de estímulos pelo tato metafórico, (4) comparativos entre os grupos, entre outras variáveis relevantes. Os achados do presente estudo são curiosos para a temática e mostra a pertinência de novos estudos no campo experimental para a temáticaThis work presents an experimental study of the metaphorical verbal behavior by checking the effects of this phenomenon on subsequent verbal responses. Twenty-five college student from a public university in the state of São Paulo were participants. Through problem situations, it was proposed an investigation of the stimulus control of metaphorical tact (\"beast\" and \"virus\") as verbal history described by the experimenter. There were different experimental conditions for each metaphorical tact which required a subsequent verbal responses of each participant, after reading an informational text. Subsequent verbal responses were: the participants indicated among the best alternatives for resolving problems between fictitious preventive and corrective measures and the participants reported to an unknown person about the text that the participants read. The experiment had the hypothesis that participants tend to give preventive measures, when read the text with the metaphorical tact of \"violence\" compared to a \"virus\" or corrective measures, if they read the information text with tact metaphorical of \"violence\" compared to a \"beast\". The individual participants were asked to perform the same protocol tasks requested in the Baseline and Experimental Condition. This protocol had four tasks, namely (1) reading informational text (2) choosing between preventive or corrective alternative to solve social problems such as hunger in the Baseline and violence in Experimental Condition, (3) showing control on the responses of previous tasks and (4) intraverbal behavior, that is, telling about the informational text read in the first task for an unknown person, which showed up virtually. In the Experimental Condition, participants in each group had contact with informational text presented through different metaphors (G-I and G-II groups), without metaphor (G-III group) and arbitrary stimuli (words without meanings) compared to different metaphors (G-IV and GV groups). In all experimental conditions, there was participant\'s performance evaluation as speaker and listener of his own verbal behavior. The experiment brought compelling data between the experimental groups, as members of the group (a) G-I replicated data from previous studies in only 20% of participants\' responses, (b) G-II remained verbal control in 80% of verbal responses subsequent, by pointing by preventive options before the \"virus\" metaphor (c) G-III showed a prevalence of participants with preventive options, since all accounted for this alternative, (d) G-IV confirmed the previous survey data keeping a relationship between the \"beast\" metaphorical tact and 60% subsequent verbal responses with corrective options, while (e) G-V established the metaphorical verbal control over 100% of subsequent verbal responses with preventive measures. In the data discussion, it was emphasize (1) life history and experimental history, (2) current and cultural contexts present in the lives of the participants, (3) stimulus control of metaphorical tact, (4) comparison between groups, and other relevant variables. The findings of present study are curious and inspires more studies in the experimental field of the theme

Full textAbstract:
Osteoarthritis (OA) is a degenerative condition of articular cartilage that affects more than 25 million people in the US. Joint injuries, like anterior cruciate ligament (ACL) tears, can lead to OA due to a change in articular cartilage loading. Gait analysis combined with knee joint finite element modeling (FEM) has been used to predict the articular cartilage loading. To predict the change of articular cartilage loading during gait due to various ACL injuries, a tibiofemoral FEM was developed from magnetic resonance images (MRIs) of a 33 year male, with no prior history of knee injuries. The FEM was validated for maximum contact pressure and anterior tibial translation using cadaver knee studies. The FEM was used to model gait of knees with an intact ACL, anteromedial (AM) bundle injury, posterolateral (PL) bundle injury, complete ACL injury, AM deficiency, PL deficiency, complete ACL rupture, as well as a bone-patellar tendon-bone (BPTB) graft. Generally, the predicted maximum contact pressure and contact area increased for all the ACL injuries when compared to intact ACLs. While an increase in maximum contact pressure and contact area is an indication of an increased risk of the development of OA, the percent of increase was typically small suggesting that walking is a safe activity for individuals with ACL injuries.

An experimental study was performed to develop and validate a collection and analysis protocol for human skin emanations. The protocol developed included the rubbing of glass beads on the palms and backs of hands for 20 minutes. The volatile headspace above samples were extracted by a solid-phase microextraction fiber which incorporated a composite coating of liquid polymer matrix and solid porous particles. This protocol provided robust and convenient signatures of human skin emanations and was applied to two experiments for validation. In one experiment, a set of twins donated samples and results suggested qualitative differences between samples of twins. The second experiment involved collections from four unrelated individuals over a period of one month. Multivariate analysis was applied to this data set and indicated a stable signature that can be ascribed to the individual, confirming that the protocol developed here can be extended to larger sample sets of MHC typed individuals.

Full textAbstract:
This thesis employs the Aristotelian concept of equity in acknowledging differences between individuals, which continue despite apparent increases in social uniformity. Differences affecting education are considered in the light of the Warnock Report 'Special Educational Needs', subsequent constructions of educational policy on integration, and polarisation of opinion between those holding the Report to be too radical, and potentially damaging to the education system, and those holding it not radical enough. Part One, 'Introduction', places the Report in an historical context, and in the context of contemporary thought. The Report is not revolutionary, but represents a stage in the evolution of educational theory and practice. Part Two, 'The Handicapped Person in Society', studies related concepts, differentiation and categorisation, with reference to relativistic notions of normality and deviance. Particular attention is given to the relativistic theory that 'handicap' is socially conditioned and hence avoidable, which is criticised and replaced by the thesis that serious handicaps, whilst possibly affected by social conditioning, are not socially created, but objectively real. The concept of a person is examined, and compared to that of an adult. Part Three, 'The Handicapped Person in Education', examines the philosophical debate over the contested concept of education, and then focusses on special education, leading to a review of the special methods and contents used with severely handicapped children, and of the Report's title 'Special Educational Needs'. Part Three closes by exploring the philosophies of integration and comprehensivisation. Part Four, 'Conclusion', links analysis of the principal philosophical issues raised by this study with the putative end of Special Education following the Warnock Report. This contains little that is revolutionary, yet some interpretations, made for non-educational reasons, are held to be potentially damaging to the education of handicapped people. Such interpretations largely arise from the ambiguities of the Report's use of emotive concepts.

Research psychologists often complain that practitioners disregard research evidence whilst practitioners sometimes accuse researchers of failing to produce evidence with sufficient ecological validity. The tension that thus arises is highlighted, using the specific illustrative examples of two treatment methods for post-traumatic disorder (PTSD): Eye-Movement Desensitisation and Reprocessing (EMDR) and exposure based interventions. Contextual reasons for the success or failure of particular treatment models that are often only tangentially related to the theoretical underpinnings of the models are discussed. Suggestions regarding what might be learnt from these debates are put forward and implications for future research are discussed.

Thesis (MBA) --University of Limpopo, 2011The leasing out of the shops to foreign owners in the rural areas in Greater Letaba Municipality by black businessmen is of concern to those involved in the economic development of the municipality. An exploratory business analysis approach was used to analyze this report. The previous local shop owners and foreign shop owners were interviewed to get the aspects that made the former fail to successfully run their business. The problem statement and objectives of the research are outlined by comparing the three shop owners through tables, and this paved the way for the researcher to understand different models used to run their businesses. Both local and foreign shop owners used the pricing strategy though their price differed. The foreign shop owners, present local shop owners and previous shop owners have, in terms of management been dealing with pricing, competition and system and equipment. The analyses of findings are presented also in the form of tables. The present local shop owners and foreign shop owners operate more or less the same. They network and buy more stock in order to sell it cheaper. The recommendation and conclusions will assist businesses not to fail in future.

Thesis, University of Bradford, 2012. http://hdl.handle.net/10454/5712.
Full textAbstract:
Introduction: Cellular membrane proteins, such as the cytochrome P450 enzyme superfamily (P450), have important roles in the physiology of the cell. P450s are important in metabolising endogenous molecules, as well as metabolising xenobiotic substances for detoxification and excretion. P450s are also implicated in cancer as they can act to 'negatively' de-activate or 'positively' activate cancer therapeutics. Identifying specific P450s that are highly up-regulated at the tumour site could be used to predict drug response and formulate targeted cancer therapy to help diminish systemic side-effects. Methods: Previous enrichment strategies have been unable to isolate the full complement of the P450 superfamily. To develop enrichment procedures for the P450s, a proteomic strategy was developed so that compounds could be screened for their effectiveness as general P450 probes. A standardised work-flow was created, encompassing affinity chromatography, protein concentration/desalting, followed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and high performance liquid chromatography-mass spectrometry (HPLC-MS). A ketoconazole analogue and a 2-EN analogue, with known P450 inhibition, were immobilised on a solid support for comparison to immobilised histamine. Co-factor removal, competitive elution and DTT cleavage of disulfide bonds of probes were utilised to elute bound proteins. Results/Discussion: Inhibitor-beads bound a large range of proteins, including P450's, of which some were eluted by co-factor removal, some by competitive elution. Specificity of binding was improved by optimising buffer conditions and solid supports, however non-specific binding was not totally eradicated. All human P450s from spiked samples and 18 P450s from more complex mouse liver samples were recovered using one or more ligands.

Full textAbstract:
Measuring the amount of information and of shared information in biological strings, as well as relating information to structure, function and evolution, are fundamental computational problems in the post-genomic era. Classical analyses of the information content of biosequences are grounded in Shannon's statistical telecommunication theory, while the recent focus is on suitable specializations of the notions introduced by Kolmogorov, Chaitin and Solomonoff, based on data compression and compositional redundancy. Symmetrically, classical estimates of mutual information based on string editing are currently being supplanted by compositional methods hinged on the distribution of controlled substructures.
Current compositional analyses and comparisons of biological strings are almost exclusively limited to short sequences of contiguous solid characters. Comparatively little is known about longer and sparser components, both from the point of view of their effectiveness in measuring information and in separating biological strings from random strings, and from the point of view of their ability to classify and to reconstruct phylogenies. Yet, sparse structures are suspected to grasp long-range correlations and, at short range, they are known to encode signatures and motifs that characterize molecular families.
In this thesis, we introduce and study compositional measures based on the repertoire of distinct subsequences of any length, but constrained to occur with a predefined maximum gap between consecutive symbols. Such measures highlight previously unknown laws that relate subsequence abundance to string length and to the allowed gap, across a range of structurally and functionally diverse polypeptides. Measures on subsequences are capable of separating only few amino acid strings from their random permutations, but they reveal that random permutations themselves amass along previously undetected, linear loci. This is perhaps the first time in which the vocabulary of all distinct subsequences of a set of structurally and functionally diverse polypeptides is systematically counted and analyzed.
Another objective of this thesis is measuring the quality of phylogenies based on the composition of sparse structures. Specifically, we use a set of repetitive gapped patterns, called motifs, whose length and sparsity have never been considered before. We find that extremely sparse motifs in mitochondrial proteomes support phylogenies of comparable quality to state-of-the-art string-based algorithms. Moving from maximal motifs -- motifs that cannot be made more specific without losing support -- to a set of generators with decreasing size and redundancy, generally degrades classification, suggesting that redundancy itself is a key factor for the efficient reconstruction of phylogenies. This is perhaps the first time in which the composition of all motifs of a proteome is systematically used in phylogeny reconstruction on a large scale.
Extracting all maximal motifs, or even their compact generators, is infeasible for entire genomes. In the last part of this thesis, we study the robustness of measures of similarity built around the dictionary of LZW -- the variant of the LZ78 compression algorithm proposed by Welch -- and of some of its recently introduced gapped variants. These algorithms use a very small vocabulary, they perform linearly in the input strings, and they can be made even faster than LZ77 in practice. We find that dissimilarity measures based on maximal strings in the dictionary of LZW support phylogenies that are comparable to state-of-the-art methods on test proteomes. Introducing a controlled proportion of gaps does not degrade classification, and allows to discard up to 20% of each input proteome during comparison.

This thesis studies two topics in sequence analysis. In the first part, we investigate the large deviations of the shape of the random RSK Young diagrams, associated with a random word of size n whose letters are independently drawn from an alphabet of size m=m(n). When the letters are drawn uniformly and when both n and m converge together to infinity, m not growing too fast with respect to n, the large deviations of the shape of the Young diagrams are shown to be the same as that of the spectrum of the traceless GUE. Since the length of the top row of the Young diagrams is the length of the longest (weakly) increasing subsequence of the random word, the corresponding large deviations follow. When the letters are drawn with non-uniform probability, a control of both highest probabilities will ensure that the length of the top row of the diagrams satisfies a large deviation principle. In either case, both speeds and rate functions are identified. To complete our study, non-asymptotic concentration bounds for the length of the top row of the diagrams, are obtained for both models. In the second part, we investigate the order of the r-th, 1<= r < +∞, central moment of the length of the longest common subsequence of two independent random words of size n whose letters are identically distributed and independently drawn from a finite alphabet. When all but one of the letters are drawn with small probabilities, which depend on the size of the alphabet, the r-th central moment is shown to be of order n^{r/2}. In particular, when r=2, we get the order of the variance of the longest common subsequence.

Full textAbstract:
That inequality of pay between the sexes persists today, primarily as a result of structural inequality and particularly occupational segmentation, provides the starting point for an examination and analysis of the Equal Pay Act 1970. Its historical origins and aetiology are traced and its development and interpretation are critically examined to provide a conclusion as to its current interpretative status, relevance and effectiveness. The thesis is founded on two critical themes. Firstly, it is argued that insofar as reducing inequality in pay is concerned, legislation can only have a partial effect and commentators claiming that the Act has failed to achieve its purpose omit to take into consideration certain sociological and cultural factors which have effects which cannot be struck at legitimately within the compass of such a legislative instrument. It is contended that proponents who argue for a widening of the scope of equal pay legislation with the purpose of eliminating structural inequality conflate two constructs; legislation aimed at achieving 'fair wages' and legislation aimed at eliminating sex discrimination in pay and that it inappropriate to attempt, jurisprudentially, to achieve the former via the latter. The second critical-theme develops the thesis that the open textured nature of the domestic Act has, with limited need for amendment, been able to be interpreted flexibly, thereby striking effectively at subtle forms of pay inequality not contemplated by policy makers or the legislature until long after enactment, thus it remains an effective instrument, not a failed measure requiring repeal and replacement. What links the two critical themes is that equal pay law is currently at a crossroads following textual omissions and lack of express clarity in two recent judgments of the European Court of Justice, which if interpreted literally by domestic tribunals and courts, have the potential to distort the purpose of the Equal Pay Act transforming it from an instrument for removing pay discrimination attributable to sex (insofar as legislative intervention ever could) into an instrument of social engineering in the hands of claimants seeking 'fair wages' in the absence of any sex discrimination; no matter how laudable such a social aim, it is contended that would be an inappropriate jurisprudential consequence.

Full textAbstract:
South Africa has one of the highest prevalences of drug misuse and abuse in Africa. Salt River Mortuary (Cape Town, South Africa), along with other national Forensic Pathology Service providers, receives many cases of suspected drug-related deaths. In some cases, the traditional autopsy – when viewed together with the decedent's history – is not able to indicate whether a drug-related death is accidental or suicidal in relation to altered drug metabolism. Literature has shown that this can be investigated by sequencing gene(s) encoding the implicated metabolising enzyme(s) in a postmortem genetic analysis. However, as such an analysis would normally be performed following the obtainment of postmortem toxicological results, it is imperative to investigate whether blood samples retrieved back from a toxicology laboratory would be sufficient for the said genetic analysis, despite the handling involved in the process of toxicological investigation. To this end, blood samples from 30 deceased individuals in which drug use/abuse may have contributed to death, were collected into two red-top tubes (plain), two grey-top tubes (containing sodium fluoride and potassium oxalate) and one EDTAcontaining purple-top tube (control). DNA was immediately extracted from one of each colour tube, while the duplicate red-top and grey-top tubes first underwent a process of toxicological analyses, and then underwent DNA extraction. The concentration, degradation, purity, contamination, and quality of DNA were assessed using real-time PCR, spectrophotometry, forensic DNA profiling, and Sanger sequencing. In contrast to the grey-top tubes, the results showed that the red-top tubes were most suitable for the aforementioned genetic analysis. Overall, the study not only demonstrated that postmortem genetic analysis using samples retrieved from a toxicology laboratory is possible in the local context, but also provided guidelines around the pre-analytical phase of the analysis. These results illustrate the opportunity to investigate these toxicogenetic avenues further, particularly in future expansion of services currently provided at Salt River Mortuary, which may provide families more information about circumstances of their relative’s death.

Full textAbstract:
The Western Dairy Center at Utah State University funded this project as part of its BUILD Dairy program with support from the dairy farmers of Idaho, to investigate the problem of splits that form in cheese during storage. The bacteria, Lactobacillus wasatchensis had previously been identified as a cause of unwanted gas production in cheese and the defects then make the cheese unsuitable for cutting into slices.
The project team proposed a two-year, $150,912 project to investigate methods for determining the presence of this bacterium in cheese by extracting DNA from the cheese and looking for DNA that was specific to Lactobacillus wasatchensis. The project identified a suitable method for extracting DNA and demonstrated that methods that extract DNA directly from the cheese are not as repeatable or reliable as a method that first separates and collects the bacteria from the cheese and then extracts the DNA.
While the detection limit for identifying Lactobacillus wasatchensis in cheese of 100,000 cells per gram, was not any lower than that which can be achieved using plating methods, this work provides the benefit of laying groundwork for selection of a NDA extraction method for use with cheese. Further research can now be applied to lower this detection limit so this bacterium can be identified in cheese earlier and thus reduce the problem of slits and cracks and provide a higher value of the cheese to the manufacturer.

Previous issue date: 2010-06-17The present study had the purpose to verify if a report request from a therapist s verbal report classes on ongoing clinical counseling could affect his performance on future therapeutic sessions, as suggested in literature. Therefore, a procedure from an early study was replied apart from changes on the response classes investigated. One psychology therapist and one client participated in this study and 11 counseling sessions were recorded on video. The therapist s verbal responses were categorized according to the Multidimensional System For Coding Behaviors In Therapist-Client Interaction and measured by occurrences. The therapist s verbal responses were requested after the fourth and eighth sessions concerning previous sessions and categorized as analysis reflexion request and recommendation. The results confirm the replied study suggesting that reports request can modify the therapist behavior in future sessions. It was identified a low correspondence between observed and reported verbal responses differently from previous study. The research line seems relevant for providing knowledge regarding the verbal processes that interfere on therapists behavior when submitted to supervision sessions and probably the clients behavior in counseling sessions
O presente de estudo teve como objetivo verificar se a solicitação de relatos sobre classes de respostas verbais de um terapeuta em atendimento clínico pode afetar seu desempenho em sessões terapêuticas posteriores, como sugerido na literatura. Para tanto, foi replicado o procedimento de um estudo anterior alterando-se as classes de respostas investigadas. Participaram deste estudo um terapeuta e um cliente e foram registradas em vídeo 11 sessões de atendimento. As respostas verbais do terapeuta foram categorizadas segundo o Sistema Multidimensional de Categorização de Comportamentos na Interação Terapêutica e mensuradas por ocorrência. Respostas verbais do terapeuta foram solicitadas, após a quarta e a oitava sessões, referentes a classes de respostas verbais observadas em sessões anteriores e categorizadas como solicitação de reflexão de análise e recomendação. Os resultados corroboraram o estudo replicado sugerindo que a solicitação de relatos pode alterar o comportamento do terapeuta em sessões futuras. Observou-se uma baixa correspondência entre as respostas verbais observadas nas sessões e as relatadas pelo terapeuta, diferentemente do estudo replicado. Esta parece ser uma linha de pesquisa relevante, por produzir conhecimento sobre os processos verbais que interferem no responder de terapeutas quando submetidos a sessões de supervisão, e possivelmente de clientes em sessões terapêuticas

In recent years the use of the simple caution has been the focus of media criticism and Government review. Most often because of allegations that it is too often used as a ‘soft option’ for more serious and repeat offenders. In antithesis, this study explored the psychological factors that led to the acceptance of a simple caution in a group of adults who later sought legal redress on grounds that the caution had been unfairly administered, and for whom the consequences of accepting a caution were often significant. The researcher adopted a constructionist position and employed a qualitative approach to explore this previously un-researched area. Thirteen adults, who had successfully challenged or were in the process of challenging a simple caution, were recruited to the study and were interviewed. Using an inductive thematic analysis, four themes were identified, each with sub-themes: Presumed innocent related to constructions of criminality and participants’ perceptions of themselves as non-criminal; Responses to arrest focused on the emotional response to police detention; Suspect vulnerability considered how naivety and the actions of the police led to the acceptance of a caution; and, The not so simple caution examined the consequences of accepting a caution and the reasons for challenge. The findings illustrate that innocence and naivety, and the need to escape, were primary motivating factors for accepting a caution, and that participants were often unaware of the consequences of accepting this disposal until after they had left the police station. The thesis concludes with some reflections on the process and consideration of how the results might inform future practice.
