Full textAbstract:
The paper attempts to overview the ideology and the class division amongst factions in the novel. The ideology of the five factions in the future city of Chicago is embedded with self traits which dictates that everyone must fit into one dominant trait. The classification by traits or personalities makes clear provision that society will run as it is expected by the leader of the faction. The Divergent of Veronica Roth postulates the depiction of the utopia society that turns Dystopia by the insurgent led by Tris a character that possesses all the qualities and traits of the faction. The culture and the ideology of bourgeois and slave’s society prevail vividly in the novel which is indicated by the ruling faction, Erudite as the bourgeois while the subjugated faction, Abnegation as the slave society. This paper utilizes the descriptive approach to meticulously break down the events by selecting and highlighting the occurrences in the novel as the way of obtaining the data. The theory of ideology by Raymond Williams (1977) was used in this paper to expose the core or base of cultural ideology amongst the classes. The paper finds out that the every faction has its own ideologies even though they were rooted from the same founding fathers.

BackgroundAnorexia nervosa (AN) is associated with behavioral traits that predate the onset of AN and persist after recovery. We identified patterns of behavioral traits in AN trios (proband plus two biological parents).MethodA total of 433 complete trios were collected in the Price Foundation Genetic Study of AN using standardized instruments for eating disorder (ED) symptoms, anxiety, perfectionism, and temperament. We used latent profile analysis and ANOVA to identify and validate patterns of behavioral traits.ResultsWe distinguished three classes with medium to large effect sizes by mothers' and probands' drive for thinness, body dissatisfaction, perfectionism, neuroticism, trait anxiety, and harm avoidance. Fathers did not differ significantly across classes. Classes were distinguished by degree of symptomatology rather than qualitative differences. Class 1 (~33%) comprised low symptom probands and mothers with scores in the healthy range. Class 2 (~43%) included probands with marked elevations in drive for thinness, body dissatisfaction, neuroticism, trait anxiety, and harm avoidance and mothers with mild anxious/perfectionistic traits. Class 3 (~24%) included probands and mothers with elevations on ED and anxious/perfectionistic traits. Mother–daughter symptom severity was related in classes 1 and 3 only. Trio profiles did not differ significantly by proband clinical status or subtype.ConclusionsA key finding is the importance of mother and daughter traits in the identification of temperament and personality patterns in families affected by AN. Mother–daughter pairs with severe ED and anxious/perfectionistic traits may represent a more homogeneous and familial variant of AN that could be of value in genetic studies.

The relation between individual trait differences, social mobility and social structure is central to social biology. Because genetic variance underlies phenotypic variance in some of these traits, for example IQ, several mechanisms determine the population variance. Polygenic inheritance is the basic mechanism. Social mobility and assortative partner choice distribute the trait variance within generations. This feedback circle is constrained by sociological conditions at several levels of analysis. Fundamental to this theory of social assortment is the relation between social–biological traits and social class on the one hand, and these traits and social mobility on the other hand. The focus here is on the relation between social class, social mobility and cognitive ability. The National Child Development Study is drawn upon, including the last follow-up (1999–2000). By approaching this relationship through various methods, both social–biological and sociological aspects of this research question can be assessed.

Abstract Objective: Considering that the available studies on prevalence of malocclusions are local or national-based, this study aimed to pool data to determine the distribution of malocclusion traits worldwide in mixed and permanent dentitions. Methods: An electronic search was conducted using PubMed, Embase and Google Scholar search engines, to retrieve data on malocclusion prevalence for both mixed and permanent dentitions, up to December 2016. Results: Out of 2,977 retrieved studies, 53 were included. In permanent dentition, the global distributions of Class I, Class II, and Class III malocclusion were 74.7% [31 - 97%], 19.56% [2 - 63%] and 5.93% [1 - 20%], respectively. In mixed dentition, the distributions of these malocclusions were 73% [40 - 96%], 23% [2 - 58%] and 4% [0.7 - 13%]. Regarding vertical malocclusions, the observed deep overbite and open bite were 21.98% and 4.93%, respectively. Posterior crossbite affected 9.39% of the sample. Africans showed the highest prevalence of Class I and open bite in permanent dentition (89% and 8%, respectively), and in mixed dentition (93% and 10%, respectively), while Caucasians showed the highest prevalence of Class II in permanent dentition (23%) and mixed dentition (26%). Class III malocclusion in mixed dentition was highly prevalent among Mongoloids. Conclusion: Worldwide, in mixed and permanent dentitions, Angle Class I malocclusion is more prevalent than Class II, specifically among Africans; the least prevalent was Class III, although higher among Mongoloids in mixed dentition. In vertical dimension, open bite was highest among Mongoloids in mixed dentition. Posterior crossbite was more prevalent in permanent dentition in Europe.

Full textAbstract:
Growth curves of Nellore cattle were analyzed using body weights measured at ages ranging from 1 day (birth weight) to 733 days. Traits considered were birth weight, 10 to 110 days weight, 102 to 202 days weight, 193 to 293 days weight, 283 to 383 days weight, 376 to 476 days weight, 551 to 651 days weight, and 633 to 733 days weight. Two data samples were created: one with 79,849 records from herds that had missing traits and another with 74,601 from herds with no missing traits. Records preadjusted to a fixed age were analyzed by a multiple trait model (MTM), which included the effects of contemporary group, age of dam class, additive direct, additive maternal, and maternal permanent environment. Analyses were carried out by a Bayesian method for all nine traits. The random regression model (RRM) included the effects of age of animal, contemporary group, age of dam class, additive direct, permanent environment, additive maternal, and maternal permanent environment. Legendre cubic polynomials were used to describe random effects. MTM estimated covariance components and genetic parameters for birth weight and sequential weights and RRM for all ages. Due to the fact that covariance components based on RRM were inflated for herds with missing traits, MTM should be used and converted to covariance functions.

Full textAbstract:
The genetic parameters for maternal rearing-ability of ewes were investigated by ignoring or defining the rearing ability trait separately by litter-size class (singles versus multiples) using multi-generational data from three, fully pedigreed Merino flocks differing in prolificacy, production level and environment. Genetic correlations (ra) between litter size (LSIZE) and the percentage of lambs surviving (PLSURV) were more negative with an increasing mean flock litter size (ra: –0.21 ± 0.17 to –0.73 ± 0.08), while the corresponding range in phenotypic correlations (rp) was substantially lower (rp: –0.15 ± 0.01 to –0.33 ± 0.01). Rearing-ability traits defined separately by litter-size class were highly correlated (ra: 0.49 ± 0.19 to 0.64 ± 0.38), but not genetically identical traits in the most prolific flock. Defining rearing-ability traits separately by litter-size class reduced the antagonistic genetic correlations between LSIZE and PLSURV to between –0.39 ± 0.14 and 0.14 ± 0.28, through accommodating the change in mean and variance of PLSURV with LSIZE. Similarly, linear transformation (TSURV) of PLSURV within each litter size to a common mean and variance reduced the antagonistic trend in genetic correlations between LSIZE and TSURV to range between –0.05 ± 0.17 and –0.43 ± 0.13. Since genetic correlations are low to moderate between TSURV and LSIZE, it is possible to select for improvements in both the number of lambs born and lamb survival simultaneously. Defining rearing-ability traits separately by litter-size class and the role of transformation will be investigated further for improving the accuracy of genetic evaluation for rearing ability across a range of flocks, breeds and environmental conditions using more extensive industry data.

Full textAbstract:
Economic values of 15 production and functional traits for Slovakian Pied cattle were calculated under different marketing strategies. The traits were as follows: birth weight of calves, daily gain of calves in fattening, mature weight of cows, weight of calves at 120, 210 (weaning weight) and 365 days (yearling weight) of age, dressing percentage, mean class for fleshiness and fat covering, conception rate of heifers and cows, losses of calves at calving and from 48 hours to weaning, lifetime of cows and mean class for calving performance. A purebred cow-calf pasture system producing its own female and male replacement was assumed for all strategies. The following marketing strategies for surplus weaned female and male calves were taken into account: (A) export of all surplus calves, (B) intensive fattening of all surplus calves, (C) rearing and selling of all surplus non-pregnant (1) or pregnant (2) breeding heifers and fattening or export of surplus male calves. All calculations were carried out with the computer program Ecoweight. The relative economic importance of traits was calculated multiplying the economic values by the genetic standard deviations of the traits. The lifetime of cows was the most important trait when applying export or fattening of all calves or when selling pregnant breeding heifers, whereas the yearling weight was even more important for the strategy with selling non-pregnant heifers. The second most important trait was weaning weight in strategy A, yearling weight in strategy B and lifetime of cows in marketing strategy C. Carcass conformation traits had the lowest economic importance in all calculations.

Objective: Autism Spectrum Disorders (ASD) and ADHD are assumed to be the extreme manifestations of continuous heterogeneous traits that frequently co-occur. This study aims to identify subgroups of children with distinct ASD–ADHD trait profiles in the general population, using measures sensitive across both trait continua, and show how these subgroups differ in cognitive functioning. Method: We examined 378 children (6-13 years) from a population-based sample. Results: Latent class analyses (LCA) detected three concordant classes with low (10.1%), medium (54.2%), or high (13.2%) scores on both traits, and two discordant classes with more ADHD than ASD characteristics (ADHD > ASD, 18.3%) and vice versa (ASD > ADHD, 4.2%). Findings suggest that ASD and ADHD traits usually are strongly related in the unaffected population, and that a minority of children displays atypical discordant trait profiles characterized by differential visual-spatial functioning. Conclusion: This dissociation suggests that heterogeneity in ASD and ADHD is rooted in heterogeneity in the lower unaffected end of the distribution.

Full textAbstract:
In this essay, I analyse the characters of Frodo and Aragorn in Tolkien’s The Lord of the Rings and Peter Jackson’s film trilogy in order to see if traits and relationships are consistent between the novel and the films. Any changes in characters and the ways they interact in relationships entail changes not only to the overarching narrative, but potentially to the most important themes of the story: friendship and heroism. This is important for the general discourse on the films as adaptations, since they have been accused of not being true to the thematic core of the source material. Peter Jackson’s claim that the intention was to always remain true to the spirit of Tolkien’s novel, then necessitates a closer comparison of the two works. Therefore, in investigating the characters I look not only for differences and similarities, but also for the repercussions these have on the story and the potential reasons behind them. By examining the characters from the perspective of the novel, the films and the filmmakers’ commentaries, I discuss how the removal of social class in the films changes the actions of the characters and consequently affects the themes of friendship and heroism. I also bring up the effects of changing from a novel to film as well as the symbiotic relationship between the character traits and the narrative as a whole. This essay shows that though the social class, character traits and the narrative flow are changed in a circular pattern. A closer look at the films reveals that the story’s core themes of friendship and heroism not only remain consistent, but are given more emphasis than in the novel.

I denna uppsats utforskas tankegods och diskurser i statens offentliga utredning Höjd bostadsstandard (SOU 1965:32) som utgör det huvudsakliga planeringsunderlaget inför byggandet av miljonprogrammet. Materialet har bearbetats med hjälp av kritisk diskursanalys och analyserats med hjälp av Beverly Skeggs begrepp respektabilitet för att undersöka de klassmarkörer som uttrycks i underlaget. Studiens resultat visar att det finns flera diskursiva mönster i utredningen som bygger på klassmotsättningar. Genom att reglera arbetarklassens boendemiljöer och få dem att eftersträva nya ideal skulle den historiska arbetarklassen byggas bort. De nya idealen kan förstås som en strävan efter att förändra denna samhällsgrupp och att medelklassen genom detta kunde omforma Sveriges klasshierarkier, underkuva arbetarklassen och bygga in spärrar för klasskamp. Allt detta paketerades i en vision om att bygga en modern stadsbild med flervåningshus, samtidigt som målgruppen för projektet önskade något annat.<br>The aim of this essay is to explore the planning bias in the Swedish blue books inquiry Raised housing standards (SOU 1965:32). This document was the primary planning material for theone million homes built in Sweden between 1965 and 1974, also known as The Million Programme. Using critical discourse analysis, the material has been analyzed in search of class traits expressed in the material. These discursive expressions have subsequently been analyzed with Beverly Skegg's theoretical concept of respectability. The results shows that there are several discursive patterns in the planning document which are based on class antagonism. By regulating the ordinary environments of the working class and making them strive for new ideals, the historical working class was supposed to be transformed. These new ideals for the working class can be understood as an attempt to change this social group and through this the middle class could reshape Sweden's class hierarchies, subdue the working class, and build in barriers against class struggle. All this packaged in a vision of building a modern cityscape with apartment buildings, whilst the target group sought for something else.

Full textAbstract:
Survey research plays a significant role in the way psychologists investigate key relationships which impact human behaviours—and which inform us about undercurrents of a population. Samples are generally taken with the primary function of being able to make inferences which can be generalised to the target population—however, historically the field has consistently relied on small and niche datasets which are not truly representative of the general population. As a consequence, there is an abundance of published research which lacks ecological validity. The alternative approach is to collect larger amounts of data—this approach is extremely costly and in most instances impractical for the researcher. I have termed this conundrum, the cost-insight trade-off, which has traditionally exasperated psychologists. To address this dilemma, I conducted three studies using two alternative methods. Study 1 investigated the relationship between social status and international friendships at a micro and macro level. The building social status hypothesis states that higher social status individuals would reach out more to people and have more international friendships than their poorer counterparts. In contrast, the restrictive social status hypothesis states the higher social status individuals would be reclusive and have fewer international friendships than their poorer counterparts. Findings at both the micro (N = 857; U.S. participants) and macro levels (approximately 50 billion friendships across 187 countries) were in alignment with the restrictive social status hypothesis. Investigating this relationship at this large a scope would not have been possible without utilising Facebook Data—furthermore, for most research projects collecting data at this scale is both too costly and impractical. Study 2 aims to address the limitation of study 1. In this light, a new alternative method, the Survey Forecasting Method, is introduced and used to demonstrate creative capability of combining the latest technology, machine learning techniques and big data (i.e. Twitter). The findings were proof positive that a data collection of only 1,000 participants (at minimum) can be transformed into the power of having a dataset of several hundred thousand participants. In other words, the findings suggest that it is possible to efficiently and effectively forecast scores for potentially millions of people, without them having to complete a single survey. This is a significant step towards developing an alternative survey method; however, the method has only been applied to the Big Five & NEO-IPIP personality traits. Study 3 provides further evidence for the Survey Forecasting Method as a viable alternative to traditional sampling methods. The study examined the relationship between entrepreneurs’ self-efficacy, fear of failure, and well-being at two levels: (a) self-report and forecasted individual level, and (b) forecasted state level (across all 50 U.S. states). Findings show there are differences between each level which provides insights into effects and potential mechanisms which would not potentially be found using traditional “silo’d” methods. The primary aim of this thesis is to provide a viable alternative method to conducting survey research—which allows the researcher to gain deeper insights into the population at less cost and time. Furthermore, this alternative method addresses poor data representativeness. Limitations are addressed and future directions to improve its capability and robustness as a viable survey research methodology are provided.

Full textAbstract:
In latent variable models the existence of one or more unobserved (latent) variables is posited to explain the associations between a set of observed (manifest) variables. These models are useful for analysing attitudinal survey data, where multiple items are used to capture complex constructs such as attitudes, which cannot be directly observed. In such research they are most commonly applied in the form of factor analyses based on linear regression models. However, these are inappropriate when observed items are categorical, which is often the case with attitudinal surveys. Latent trait and latent class models, based on logistic models, are then more suitable. In this thesis I demonstrate how they can be employed to address common challenges in attitudinal survey research. The case study data illustrating these challenges are from the Eurobarometer survey on public perceptions of biotechnology, fielded in 2002 in fifteen European countries. Using these data I investigate the viability of cross-nationally comparable measures of three central constructs in studies of public perceptions of biotechnology: attitudes towards applications of biotechnology, knowledge of biology and genetics, and engagement with science and with biotechnology. The analyses aim to capture these complex constructs, taking account of 'don't know' responses by including them as categories of nominal observed items, and exploring the comparability of measures of these constructs cross-nationally by assessing the similarity of measurement models between countries. The results of these analyses are informative in three ways: substantively, adding to our knowledge of people's representations of biotechnology; methodologically, increasing our understanding of how the survey items function; and practically, informing future questionnaire design. I also formulate a taxonomy of issues and choices in attitudinal survey research as a conceptual framework through which to discuss more broadly the potential value of latent trait and latent class models in survey research in social psychology.

Full textAbstract:
Commentary on skilled trades occupations in Canada has been framed by two main
paradigms: The dominant policy discourse has applied human capital theory to the
dynamics of the skilled labour supply, often concentrating on intractable “problems”
such as low apprenticeship participation and completion rates and an extreme gender
imbalance in the trades. Sociological research has portrayed trades occupations as
positions of structurally reproduced social disadvantage. This study adopts an
alternate, neo-Weberian framework centred on the theory of economic social action.
Social structure is treated in strictly nominalistic terms, and social action is rooted in the interest-oriented behaviour of socially embedded individuals. The study,
undertaken in a large public-sector shipyard, involved both a pen-and-paper survey
(N=509) of skilled trades workers and ten focus group interviews with 49 respondents
from labour and management. The research questions addressed indicators of structural (dis)advantage and reproduction, as well as the specific mechanisms of social action operating within the study environment. The population shows a very distinct profile in terms of gender, ethnicity, and educational investment. Data on earnings, job security, and working conditions dispel any suspicion of economic disadvantage. Although a high proportion of incumbents have family connections to the skilled trades, an analysis of their siblings’ occupations refutes the supposition of structural determinism through the family. Instead, it is argued that both the social profile of the workforce and the high density of family and network connections reflect the use of “bridging” and “bonding” social capital strategies by study population members. The operative mechanisms include formal elements of the organization’s hiring practices, as well as institutionalized group norms and workplace culture. Through a “separatist” discourse that invokes notions of both “trade stigma” and “trade pride,” incumbents ascribe a particular set of cognitive and moral attributes to trades workers, which also contribute to defining the formal and informal membership requirements for their occupations. By approaching occupations as sites of economic social action, this research concludes that some of the intractable “problems” in Canada’s apprenticeable trades reflect individual behaviours that are enabled and incited by institutional features integral to the present skilled trades system.

Partant des difficultés à ponctuer des jeunes scripteurs québécois que sont des élèves de la fin du primaire et du début du secondaire, ce travail s'intéresse à la ponctuation comme objet de savoir savant devenu scolaire par le processus de transposition didactique, processus par lequel tout objet subit nécessairement de nombreuses transformations pour finalement devenir une « création » scolaire. Une synthèse des travaux sur la ponctuation, depuis sa création jusqu'à aujourd'hui, sous l'angle de la linguistique, de la psycholinguistique, de la psychologie du langage et de la didactique du français révèle un problème inquiétant lié à la didactisation-même de ce sous-domaine de la grammaire : et si l'école s'était mal approprié l’objet? L'étude du domaine, qui de l'avis des spécialistes constitue un système, fait ressortir certaines caractéristiques traitées avec peu de rigueur dans les outils auxquels ont accès les enseignants de français pour planifier et dispenser leur enseignement de la ponctuation : multiples fonctions de la ponctuation, choix des éléments qui constituent l'ensemble, liens entre les fonctions pouvant être exercées par ces signes, etc. Les didacticiens du français ont mis à jour l'importance de faire comprendre aux élèves le rôle énonciatif des signes de ponctuation, en écriture aussi bien qu'en lecture, en lien avec les genres ainsi qu’au nécessaire arrimage de la progression dans l'enseignement des emplois des signes avec le développement progressif des compétences scripturales des élèves. Or, le traitement de la ponctuation dans les documents auxquels les enseignants de français québécois et francophones ont accès s'avère problématique : contradictions, non-sens et zones grises sont observables dans les programmes d'enseignement, documents liés à la progression des contenus, manuels et grammaires scolaires ainsi que grammaires de référence. La prise de conscience de ces lacunes constitue un tremplin pour une didactisation de l'objet et, pour ce faire, des pistes de travail existent.

Dans cette thèse, on étude le complexe des cycles proches d'un faisceau l-adique sur un schéma au-dessus d'un trait en utilisant la théorie de ramification d'Abbes et Saito. La première partie est consacrée à une nouvelle preuve d'une formule de Deligne et Kato qui calcule la dimension du complexe des cycles proches d'un faisceau l-adique sur une courbe relative lisse au-dessus d'un trait strictement local.

The first part is devoted to a new proof of a formula of Deligne and Kato that computes the dimension of the stalks of the nearby cycle complex of an l-adic sheaf on a smooth relative curve over a strictly local trait. Deligne considered the case where the sheaf has no vertical ramification and Kato extended the formula to the general case. Our approach is based on a local notion of characteristic cycle defined using the refined Swan conductor of Abbes and Saito. In the second part, we prove a formula that computes the Swan conductor of the cohomology of the nearby cycle complex of an l-adic sheaf on a smooth variety over a trait of equal characteristic, satisfying a certain ramification condition. Tsushima introduced the refined characteristic class of the sheaf and he proved that it computes the Swan conductor of the cohomology of its nearby cycle complex by a Lefschetz-Verdier type formula.We compute the refined characteristic class as an intersection product on the logarithmic cotangent bundle of the variety, involving the characteristic cycle of the sheaf defined by Abbes and Saito and the zero section

Cette thèse, porte sur la jeunesse ouvrière aujourd'hui. A partir d'une enquête ethnographique approfondie et multiple (entretiens, observations, contacts informels, partage d'activités. . . ), j'ai essayé de comprendre, dans le temps, comment les identités sociales des jeunes ouvriers se façonnent avant d'entrer dans l'emploi public puis une fois qu'ils y entrent, dans l'atelier comme en dehors. Pour appréhender les enquêtés dans leur nuance et leur complexité, j'ai mêlé plusieurs champs de la sociologie : la sociologie du travail et de l'emploi mais aussi de l'école, de la culture. . . En inscrivant ce travail dans la durée, on se donne les moyens de comprendre comment les identités obéissent à des processus et se façonnent de manière singulière : des aspirations nourries lors du passage par l'école jusqu'aux premiers jours dans l'atelier, puis de la pérennité de la condition ouvrière jusqu'à des identités compensatrices permettant de dire qu'ils ne sont pas uniquement ouvriers, en tout cas pas comme la génération précédente. Leurs activités parallèles (cours du soir, musique, danse, vacances à l'UCPA. . . ) leur permettent, même s'ils se rendent compte qu'ils sont devenus ouvriers bien en-deça de ce qu'ils imaginaient, de pouvoir continuer à s'imaginer proches de ces classes moyennes souvent fantasmées dont ils n'ont, quand ils les ont côtoyé un certain temps à l'école, jamais totalement fait le deuil de ne pas faire partie. Cette situation révèle finalement un certain entre-deux qui questionne les représentations de la stratification sociale actuelle<br>This thesis focuses on today Young workers. Based on a thorough and multiple ethnographical investigation (interviews, observations, informal contacts, sharing of activities…), I’ve tried to sort out, in the long-term, how Young working-class social identities build themselves before joining public services and after they have integrated them, in and out of the factories. To understand the people I chose to interview within their specificity and complexity I mingled several sociology fields, which not only means work but also school, family, culture etc… Only an investigation within the long terme may help understand how identities obey to evolutions and take peculiar shapes : hopes developed throughout their scholarship until their very first days in the factories, then through the long-lasting working class condition to compensating identities that enable them to say they are not only workers, at least, not like the previous génération. Their parallel activities (evening class, music, dance, holidays with the UCPA…) help them considering themselves, even though they may some day realize they are not as qualified as the expected to be, familiar to this middle class they have often idealized and that they have never fully accepted not to be part of, when they have interacted with if for some time at school. This situation reveals a real ambiguity that questions the representations of social stratification that exist today

Abstract Positive intelligence (PI) training can produce a transformative impact on college students. PI, a branch of human psychology, provides a tool to identify significant compulsive habits that can inhibit students’ learning potential and ability to understand others. This paper discusses the two training methods adopted for teaching graduate and undergraduate students. It is considered that including such training is fundamentally crucial for developing 21st century STEM workforce with a well-rounded personality. However, PI training may consume a significant class time allocated for covering course contents under the degree-specific curriculums. Starting a new course may increase the credit overload beyond the approved BS and graduate credits. This paper discusses introducing different modules in the existing classes to foster PI training. The PI training method for undergraduate students focuses on self-education via online videos and freely available content and self-assessment tests. Undergraduate students were given a set of questions to guide them about the important PI topics and to pay attention while self-learning the PI elements. The PI assignment starts with the familiarization of the Maslow hierarchy of needs governing the motivation behind human actions. This assignment mainly focuses on understanding the “sage” mode in which a human tends to utilize his/her latent and earned skills towards the attainment of goals and living life purposefully. The PI assignment had several questions on self-sabotaging “saboteurs” and judging traits that almost everyone develops as a survival mechanism while facing emotional and physical survival challenges for an extended period. During class discussion, students were exposed to their hidden/invisible saboteurs which could be easily triggered by unrealistic mental threats and thus compromise their learning function and performance. Students were asked to take free online self-assessment saboteur test to find the numerical values of their traits and do self-evaluation and plan to counteract the effect of self-sabotaging habits. PI training fulfills ABET student learning outcomes focusing on developing their life-long learning skills. This paper mainly discusses the PI training for graduate students under the mechanical engineering department. PI training is one of the first and essential modules in the mandatory MECH 500 Research Methods and Technical Communication course. Graduate students enrolled in this course are first introduced to the importance of PI and its potential impact in developing self-efficacy. After the initial introduction, graduate students are asked to do the following (a) Complete the abovementioned assignment given to the undergraduate student, (b) prepare a presentation on PI by including their insights for class discussion. After the PI training, students were asked to reflect on their competence in PI and the ability to apply it. In the survey and direct feedback, students expressed the value and appreciation for the PI training. Students also expressed the need to provide this training to large masses for developing an emotionally mature society of parents, teachers, and students, producing creative, innovative, and emphatic civilization.

Full textAbstract:
The positive unlabeled (PU) learning aims to train a binary classifier from a set of positive labeled samples and other unlabeled samples. Much research has been done on this special branch of weakly supervised classification problems. Since only part of the positive class is labeled, the classical PU model trains the classifier assuming the class-prior is known. However, the true class prior is usually difficult to obtain and must be learned from the given data, and the traditional methods may not work. In this paper, we formulate a convex formulation to jointly solve the class-prior unknown problem and train an accurate classifier with no need of any class-prior assumptions or additional negative samples. The class prior is estimated by pursuing the optimal solution of gradient thresholding and the classifier is simultaneously trained by performing empirical unbiased risk. The detailed derivation and theoretical analysis of the proposed model are outlined, and a comparison of our experiments with other representative methods prove the superiority of our method.

Full textAbstract:
This paper addresses similarities between various nutating or wobbling mechanisms, especially kinematic similarities. A case is made for the generalization of several mechanisms into a mechanism “class” having common kinematic characteristics. This mechanism class is shown to be typified by bevel epicyclic gear trains. It is proposed that not only kinematic analysis, but static-force, power-flow, and efficiency analyses of mechanisms belonging to this “class” can be simplified by modeling them as bevel-gear trains. Simplified kinematic, force, and efficiency analyses are demonstrated for a novel wobbling speed reducer using this concept of “equivalent” geared mechanisms. The reduction in complexity of these analyses is the main motivation for this work.

Full textAbstract:
In 2011, Canadian Pacific (CP) implemented a new Automated Train Brake Effectiveness (ATBE) process for coal trains which replaces the visual Class 1 (No.1) Air Brake test required under Canada’s Department of Transport (Transport Canada – TC) regulations. The ATBE process relies on Wayside Detector technology to assess the operation of brakes on each railcar under dynamic conditions. CP began analyzing wayside detector information in 2008 as the basis for evaluating the braking performance of coal trains in Canadian Export service, specifically targeting existing Hot Box / Hot Wheel Detectors strategically situated alongside the track. Using the wayside detector output, the new ATBE process improves upon the visual No.1 Brake Test by evaluating brake effectiveness. The wayside detector information is automatically transmitted to a central Equipment Health Monitoring System after each train passing, where train brake effectiveness is evaluated and results published to mechanical maintenance facilities and train crews. The published results constitute the completed ATBE Test for the train. Given the substantial number of mechanical components requiring visual inspection each day by railway train inspectors, and taking into account the considerable investment CP has made into Wayside Detection technology, focus has moved towards Technology Driven Train Inspections (TDTI), preferring predictive, proactive maintenance practices and condition-based maintenance policies instead of the traditional reactive maintenance approach.

Full textAbstract:
The noise resulting from stopping a moving train is often a source of annoyance to both passengers and people who work and sometimes live in the vicinity of railroad stations. The present study attempted to define the characteristics of noise produced by the brakes of trains used in Portugal. The braking process varies widely from train to train and within the same type of train. Therefore, the results of the measurements had to be statistically analyzed. The parameters used to describe noise in this situation were the LAeq, the L10 and the L90 and the corresponding measurements took place both during the daytime and the nighttime period. Data was also obtained as a function of time and in 1/1 octave bands. The results show that there is a direct correlation between the maximum speed of a given train and the corresponding sound pressure level when the train is stopped. It was found that passenger trains that belong to the new, upper class of railroad transportation were the noisiest ones at the time of braking. As to the railroad itself, it was found that long welded rails make a favorable contribution to the decrease of noise levels. It was also found that the nighttime period was less noisy than the daytime period, in particular in terms of LAeq and L10.

Full textAbstract:
Objectives/Scope Perfluoroelastomers are a class of synthetic elastomers that provide extraordinary resistance to oils, chemicals, and heat. The outstanding thermal stability and excellent corrosion resistance of these materials is dependent on the perfluorinated polymer chain, and the absence of unsaturation. However, the cross-link which is necessary to impart elastomeric properties must also share those stability traits. Unfortunately, designing a suitably inert cross-link is technically difficult to achieve and consequently it has not been possible to provide the ultimate in perfluoroelastomer properties. This paper is a review of the cross-linking chemistry of perfluoroelastomers and highlight a novel and patented cross-link which combines broad chemical resistance and superior thermal stability. Methods, Procedures, Process Several perfluoroelastomers formulations were selected and tested using representative standardized test methods to quantify their performance. The testing included compression set resistance, swell in fluids, and compression stress relaxation. In addition to the testing, chemistry of the cross-link was explained and how it is related to the observed performance results. The novel cross-link, triazole, was identified as an improvement versus existing cross-links. Results, Observations, Conclusions The testing demonstrated that previously available perfluoroelastomer cross-link chemistries display compromises in overall performance. For example, it had not been possible to achieve high thermal stability combined with resistance to almost all fluids. Overall, the data generated showed that the newly developed triazole cross-link system broadens the performance envelope of perfluoroelastomers and helps to alleviate the compromises of the past. Novel/Additive Information The newly discovered triazole cross-link with enhanced chemical and thermal stability enables broader use of perfluoroelastomers in extreme applications.

Full textAbstract:
In order to meet the demand of passengers for travelling and make their travelling more convenient, the railway operator must ascertain the operational train number, section, classes, stop stations and appropriate departure and arrival stations for passenger trains. The nodes of railway passenger transport are the generation and attraction points of passenger flow in the railway transport network. Starting from the analysis of the economic and social attributes as well as railway resource allocation of the Passenger Dedicated Railway Line (PDRL) covered nodes, this paper introduces the concept of the importance of nodes. On the basis of analytical hierarchy process (AHP), the paper studies the quantitative index of the nodes transport distribution capacity in the PDRL network and calculates the evaluation indexes of importance of those city nodes. Thus, in the light of the assessment results, the paper sets up the three-level hierarchy in the importance of city nodes covered by the PDRL. Based on that, the paper proposes that the first-level nodes serve as the departure and arrival stations, the second-level nodes adopt the fluid and alternate stop stations, and the tertiary-level nodes take the form of “all-stop” for low-class trains so as to build a multi-objective programming model for the PDRL train line planning. With the lingo 8.0 program, the train line planning optimizes the calculation of stop stations. This method has been applied in the PDRL train line planning of Wuhan-GuangZhou High-Speed Railway Line and proved to be effective in reducing the complexity of the train line planning problem according to different modes of passenger flow.

Full textAbstract:
American Railroads are planning to complete implementing their Positive Train Control (PTC) systems by 2020. Safety objectives of PTC are to avoid inter-train collisions, train derailments and ensuring railroad worker safety. Under published specifications of I-ETMS (the PTC system developed by Class I freight railroads), the on-board PTC controller communicates with two networks; namely, the Signaling network and the Wayside Interface Unit network to gather navigational information such as the positions of other trains, the status of critical infrastructure (such as switches) and any hazardous conditions that may affect the train path. By design, PTC systems are predicated on having a reliable radio network operating in reserved radio spectrum, although the PTC system itself is designed to be a real-time fail safe distributed control systems. Secure Intelligent Radio for Trains (SIRT) is an intelligent radio that is customized to train operations with the aim of improving the reliability and security of the radio communication network. SIRT has two tiers. The upper tier has the Master Cognitive Engine (MCE) which communicates with other SIRT nodes to obtain signaling and wayside device information. To do so, the MCE communicates with cognitive engines at the lower tier of SIRT; namely the Cryptographic Cognitive Engine (CCE) (that provide cryptographic security and threat detection) and the Spectrum Management Cognitive Engine (SCE) (that uses spectrum monitoring, frequency hopping and adaptive modulation to ensure the reliability of the radio communication medium). We presented the architecture and the prototype development of the CCE in [1]. This paper presents the design of the MCE and the SCE. We are currently developing a prototype of the SCE and the MCE and testing the performance of our cognitive radio system under varying radio noise conditions. Our experiments show that SIRT dynamically switches modulation schemes in response to radio noise and switches channels in response to channel jamming.

Esta nota de clase tiene por propósito brindar a los estudiantes y futuros profesionales de la salud y a los colegas que acompañan este proceso educativo algunos elementos claves para el desarrollo y análisis de los determinantes sociales y de la salud, así como su afectación en la salud de los individuos y colectivos. El abordaje de esta temática se desarrolla paso a paso, en articulación con temas y contenidos vistos previamente en el curso. Es necesario que el estudiante recuerde el significado de salud dado por la Organización Mundial de la Salud (OMS), con el fin de vincularlo a los antecedentes investigativos, donde se relacionan la pobreza, la desigualdad y su impacto en la salud de las personas. Los modelos de determinantes sociales se usan para argumentar las causas de esa desigualdad social. De este modo, se amplía el horizonte conceptual a través de la explicación de cada uno de los determinantes sociales definidos por la OMS, mostrando sus interacciones. El desarrollo investigativo permitió concluir que los estudiantes logran identificar los determinantes sociales en una comunidad, aplicar un modelo para argumentar sus puntos de vista, e identificar la situación de salud y los riesgos personales y socioeconómicos tanto de un individuo como de una comunidad. Mediante el desarrollo de este tema, el estudiante fortalecerá su capacidad de analizar críticamente los determinantes sociales en cualquier contexto social y la afectación en la salud de individuos y poblaciones.

Perkins, Dustin. Invasive exotic plant monitoring at Colorado National Monument: 2019 field season. Edited by Alice Wondrak Biel. National Park Service, 2021. http://dx.doi.org/10.36967/nrr-2286650.
Full textAbstract:
Invasive exotic plant (IEP) species are a significant threat to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The North-ern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. This report represents work completed at Colorado National Monument during 2019. During monitoring conducted June 12–19, a total of 20 IEP species were detected on monitoring routes and transects. Of these, 12 were priority species that accounted for 791 separate IEP patches. IEPs were most prevalent along riparian areas. Yellow sweetclover (Melilotis officinale) and yellow salsify (Tragopogon dubius) were the most commonly detected priority IEPs along monitoring routes, representing 73% of all priority patches. Patches of less than 40 m2 were typical of nearly all priority IEP species except yellow sweetclover. A patch management index (PMI) was created by combining patch size class and percent cover for each patch. In 2019, a large majority of priority IEP patches were assigned a PMI score of low (46%) or very low (50%), indicating small and/or sparse patches where control is generally still feasible. This is similar to the numbers for 2017, when 99% of patches scored low or very low in PMI. Seventy-eight percent of tree patches were classified as seedlings or saplings, which require less effort to control than mature trees. Cheatgrass (Anisantha tectorum) was the most common IEP recorded in transects, found in 30–77% of transects across the different routes. It was the only species found in transects on all monitoring routes. When treated and untreated extra areas near the West Entrance were compared, the treated area had comparable or higher lev-els of IEPs than the untreated area. When segments of monitoring routes conducted between 2003 and 2019 were compared, results were mixed, due to the different species monitored in different time periods. But in general, the number of IEPs per 100 meters is increasing or remaining constant over time. There were notable increases in IEP patches per 100 meters on several routes in 2019: field bindweed (Convolvulus arvensis) along East Glade Park Road; Siberian elm (Ulmus pumila) in Red Canyon; yellow salsify along East Glade Park Road, No Thoroughfare Canyon, No Thoroughfare Trail, and Red Canyon; and yellow sweetclover in No Thoroughfare Canyon and Red Canyon. Network staff will return to re-sample monitoring routes in 2021.
