Universidad Nacional Agraria La Molina – Perú : inclusión social y discriminación social

Como ha sido observado por estudiosos de la educación superior en el Perú y en América Latina, existen dificultades estructurales para el acceso de grupos vulnerables (pobres, minorías étnicas, grupos urbano-marginales, etc.) a la educación superior de calidad. Asimismo, se observa problemas de permanencia de estudiantes sobre quienes prevalecen relaciones de discriminación en sus entornos institucionales. El proyecto titulado “Programa marco interuniversitario para la equidad y la cohesión social de las instituciones de educación superior en América latina” (RIAIPE3, 2011-2013), del que es parte la Universidad Nacional Agraria-La Molina (UNALM), en Perú, es un esfuerzo interinstitucional que entre otros propósitos tuvo: “crear y aplicar un programa marco de referencia para promover las políticas y prácticas en las instituciones de educación superior en América Latina que favorezcan la equidad en poblaciones vulnerables y considere como focos de atención: la exclusión, el acceso, la permanencia en la educación superior de las poblaciones vulnerables (población rural, indígenas, colectivos urbanos marginales, etc.)”. Es en el marco de este proyecto que se realizó el presente estudio. El presente informe de investigación da cuenta de una primera exploración de la problemática de la inclusión social en una universidad pública nacional del Perú, la Universidad Nacional Agraria-La Molina, al empezar la segunda década del siglo XXI, a partir de información de fuente secundaria y autogenerada mediante una encuesta aplicada a estudiantes de pregrado de dos grupos específicos en el segundo semestre del año 2011: estudiantes ingresantes y estudiantes que terminan su carrera.

Differential cognitive effects of Ginkgo biloba after acute and chronic treatment in healthy young volunteers

Acute doses of Ginkgo biloba have been shown to improve attention and memory in young, healthy participants, but there has been a lack of investigation into possible effects on executive function. In addition, only one study has investigated the effects of chronic treatment in young volunteers. This study was conducted to compare the effects of ginkgo after acute and chronic treatment on tests of attention, memory and executive function in healthy university students. Using a placebo-controlled double-blind design, in experiment 1, 52 students were randomly allocated to receive a single dose of ginkgo (120 mg, n=26) or placebo (n=26), and were tested 4h later. In experiment 2, 40 students were randomly allocated to receive ginkgo (120 mg/day; n=20) or placebo (n=20) for a 6-week period and were tested at baseline and after 6 weeks of treatment. In both experiments, participants underwent tests of sustained attention, episodic and working memory, mental flexibility and planning, and completed mood rating scales. The acute dose of ginkgo significantly improved performance on the sustained-attention task and pattern-recognition memory task; however, there were no effects on working memory, planning, mental flexibility or mood. After 6 weeks of treatment, there were no significant effects of ginkgo on mood or any of the cognitive tests. In line with the literature, after acute administration ginkgo improved performance in tests of attention and memory. However, there were no effects after 6 weeks, suggesting that tolerance develops to the effects in young, healthy participants.

Physiological expression of human thermal comfort to indoor operative temperature in the non-HVAC environment

A physiological experiment was carried out in a naturally ventilated, non-HVAC indoor environment of a spacious experimental room. More than 300 healthy university students volunteered for this study. The purpose of the study was to investigate the human physiological indicators which could be used to characterise the indoor operative temperature changes in a building and their impact on human thermal comfort based on the different climatic characteristics people would experience in Chongqing, China. The study found that sensory nerve conduction velocity (SCV) could objectively provide a good indicator for assessment of the human response to changes in indoor operative temperatures in a naturally ventilated situation. The results showed that with the changes in the indoor operative temperatures, the changing trend in the nerve conduction velocity was basically the same as that of the skin temperature at the sensory nerve measuring segment (Tskin(scv)). There was good coherent consistency among the factors: indoor operative temperature, SCV and Tskin(scv) in a certain indoor operative temperature range. Through self-adaptation and self-feedback regulation, the human physiological indicators would produce certain adaptive changes to deal with the changes in indoor operative temperature. The findings of this study should provide the baseline data to inform guidelines for the development of thermal environment-related standards that could contribute to efficient use of energy in buildings in China.

Social networks and positive and negative affect

We followed 100 university students in the UK for one week, instructing them to record all face-to-face, phone and digital contacts during the day as well as their positive and negative affect. We wanted to see how positive and negative affect spread around a social network while taking into account participants’ socio-demographic data, personality, general health and gratitude scores. We focused on the participants’ connections with those in their class; excluding friends and family outside this group. The data was analysed using actor-based models implemented in SIENA. Results show differences between positive and negative affect dynamics in this environment and an influence of personality traits on the average number and rate of communication.

Social consensus, moral intensity and willingness to pay to address a farm animal welfare issue

An experimental contingent valuation (CV) survey of university students was undertaken to explore the impact of social consensus information on people's stated willingness to pay (wtp) to address a farm animal welfare issue. The survey found that additional information presented to respondents on social consensus concerning the moral dimensions of the issue led to a greater perception of social consensus by respondents. This greater perception of social consensus appeared to result in a higher level of moral intensity associated with the issue and a higher stated wtp by respondents for policy to address the issue. However, as for many CV studies of public goods, a question remains as to whether the estimated wtp is a true measure of people's preferences and relative values or merely a measure of attitudes on an arbitrary monetary scale.

Emerging social norms in the UK and Japan on privacy and revelation in SNS

Semi-structured interviews with university students in the UK and Japan, undertaken in 2009 and 2010, are analysed with respect to the revealed attitudes to privacy, self-revelation and revelation by/of others on SNS.

Contract cheating & the market in essays

We conduct the first empirical economic investigation of the decision to cheat by University students. We investigate student demand for essays, using hypothetical discrete choice experiments in conjunction with consequential Holt-Laury gambles to derive subjects risk preferences. Students stated willingness to participate in the essay market, and their valuation of purchased essays, vary with the characteristics of student and institutional environment. Risk preferring students, those working in a non-native language, and those believing they will attain a lower grade are willing to pay more. Purchase likelihoods and essay valuations decline as the probability of detection and associated penalty increase.

Interactional dynamics in on-line and face-to-face peer-tutoring sessions for second language writers

This paper reports the results of a study comparing the interactional dynamics of face-to-face and on-line peer-tutoring in writing by university students in Hong Kong. Transcripts of face-to-face tutoring sessions, as well as logs of on-line sessions conducted by the same peer-tutors, were coded for speech functions using a system based on Halliday's functional-semantic view of dialogue. Results show considerable differences between the interactional dynamics in on-line and face-to-face tutoring sessions. In particular, face-to-face interactions involved more hierarchal encounters in which tutors took control of the discourse, whereas on-line interactions were more egalitarian, with clients controlling the discourse more. Differences were also found in the topics participants chose to focus on in the two modes, with issues of grammar, vocabulary, and style taking precedence in face-to-face sessions and more “global” writing concerns like content and process being discussed more in on-line sessions.

Voice, appropriation and discourse representation in a student writing task

We investigate the practices by which bilingual university students in Hong Kong appropriate texts in producing utterances, particularly written texts. Following Wertsch and his colleagues we ask: • To what extent do our students appropriate texts in constructing their own discourses? • What linguistic means do they use to do this? • What can these processes tell us about what they now can do with discourse representation; and • What do we need to teach them? This research shows that our students' writing displays considerable intertextuality and interdiscursivity. Responses to this writing in tutorial sessions indicate that they are skilled at orchestrating the multiple voices within their own discourses. The commonly stated concern that our students do not know how to do quotation and citation correctly is somewhat misplaced and researchers need to move the focus away from the mechanisms of citation and attribution to the social practices of textual appropriation.

Psychometric evaluation of the Disordered Eating Attitude Scale (DEAS). English version

Eating attitudes are defined as beliefs, thoughts, feelings, behaviors and relationship with food They could influence people`s food choices and their health status Objective This study aimed to adapt from Portuguese to English the Disordered Eating Attitude Scale (DEAS) and evaluate its validity and reliability. The original scale in Portuguese was translated and adapted into English and was applied to female university students of University of Minnesota USA (n = 224). Internal consistency was determined (Cronbach`s Alpha). Convergent validity was assessed by correlations between Eating Attitude Test-26 (EAT-26) and Restrain Scale (RS). Reliability was evaluated applying twice the scale to a sub-sample (n = 30). The scale was back translated into Portuguese and compared with the original version and discrepancies were not found. The internal consistency was .76 The DEAS total score was significantly associated with EAT-26 (r = 0.65) and RS (r = 0 69) scores The correlation between test-retest was r = 09 The English version of DEAS showed appropriate internal consistency, convergent validity and test-retest reliability and will be useful to assess eating attitudes in different population groups in English spoken countries.

DEVELOPMENT AND VALIDITY OF THE DISORDERED EATING ATTITUDE SCALE (DEAS)

The aim of this study was to develop and validate the Disordered Eating Attitude Scale to measure disordered eating attitudes, defined as abnormal beliefs, thoughts, feelings, behaviors, and relationship regarding food. Exploratory factor analysis was performed and internal consistency assessed in a sample of female university students (N=196). Convergent validity was acceptable based on statistically significant correlations with the Eating Attitude Test-26 and Restraint Scale. Known-groups validity was determined by comparing the student sample`s mean scores against scores of an eating disorder group (N=51). The Disordered Eating Attitude Scale comprises 25 questions and five subscales explaining 54.3% of total variance. The total scores differentiated student, bulimia, and anorexia groups. The scale should prove useful for evaluating eating attitudes in various population groups and eating disordered patients.

Marketing para jovens consumidores de café: estratégias para o mercado brasileiro

Empresas de diferentes setores, dentro da nova estrutura competitiva, cientes da importância de satisfazer as necessidades dos consumidores, vêm provocando mudanças nos hábitos e costumes da população. Novos alimentos e novas formas de distribuição têm sido introduzidos, acompanhados de agressivas campanhas publicitárias. O setor de café, confiante na sua tradição, não acompanhou o ritmo de modernização e de marketing do setor de bebidas, tendo como conseqüência uma significativa perda de participação no mercado e redução no consumo. Este trabalho tem como objetivo conhecer o consumidor jovem de café no Brasil e sugerir estratégias mercadológicas que possam estimulá-lo a consumir mais o produto. Através da técnica de análise de grupos foram realizados estudos qualitativos na cidade "de São "Paulo e estudos quantitativos na cidade. de Belo Horizonte. Analisados os resultados, e identificado o significado do café para este público jovem, foram sugeridas estratégias genéricas que contribuam para o aumento do consumo de café no mercado interno. Os resultados mostram que predomina, entre os jovens universitários, uma imagem negativa em relação ao café. Muito associado ao cigarro e ao vicio, 54% dos entrevistados não têm o hábito de tomar café, além de associar a imagem do café a uma pessoa adulta, que trabalha muito, estressada e cheia de responsabilidades. Quem toma aprendeu com a família, por um hábito, ou no trabalho. Como aspectos positivos consideram o café como estimulante e muito associado a um intervalo, descanso e relaxamento. Consideram que o café ainda mantém sua postura tradicional, não é um produto prático e adequado ao jovem e as propagandas não falam com o jovem. Estratégias de marketing elaboradas com vistas ao futuro consumidor de café devem descobrir os valores que norteiam os interesses dos jovens de hoje para construir produtos, embalagens, formas de consumo e de comunicação que façam sentido em seu mundo. Pois esse mundo é diferente daquele onde o café tem ou teve um lugar de honra: o lar brasileiro. Da forma como vem sendo percebido hoje pelos jovens, constata-se que é preciso mudar se quiser permanecer.

Hope, risk perception and propensity to indebtedness

Hope is an important construct in marketing, once it is an antecedent of important marketing variables, such as trust, expectation and satisfaction (MacInnis & de Mello, 2005, Almeida, Mazzon & Botelho, 2007). Specifically, the literature suggests that hope can play an important influence on risk perception (Almeida, 2010, Almeida et al., 2007, Fleming, 2008, MacInnis & de Mello, 2005) and propensity to indebtedness (Fleming, 2008). Thus, this thesis aims to investigate the relations among hope, risk perception related to purchasing and consumption and propensity to indebtedness, by reviewing the existing literature and conducting two empirical researches. The first of them is a laboratory experiment, which accessed hope and risk perception of getting a mortgage loan. The second is a survey, investigating university students’ propensity to get indebted to pay for their university tuition, analyzed through the method of Structural Equations Modeling (SEM). These studies found that hope seems to play an important role on propensity to indebtedness, as higher levels of hope predicted an increase in the propensity to accept the mortgage loan, independent of actual risks, and an increase in the propensity of college students to get indebted to pay for their studies. In addition, the first study suggests that hope may lead to a decrease in risk perception, which, however, has not been confirmed by the second study. Finally, this research offers some methodological contributions, due to the fact that it is the first study using an experimental method to study hope in Brazil and, worldwide, it is the first study investigating the relation among hope, risk perception and propensity to indebtedness, which proved to be important influences in consumer behavior

Locus de controle e reação a frustração

Este estudo visa analisar a interrelação teórica e epistemológica entre a teoria da aprendizagem social, mais precisamente em termos de seu constructo "locus de controle" de Rotter e a teoria da frustração, tal como desenvolvida por S. Rosenzweig. Através de um reestudo das ·teorias da frustração e proposto um modelo, capaz de avaliar a influência da percepção social determinada pela direção do "locus de controle" na reação à frustração. São examinadas três possíveis explicações teóricas para determinação das diferenças na percepção do controle a primeira em função da teoria da aprendizagem, a segunda em termos psicodinâmicos e a terceira em função de disposições inatas. E apresentada uma revisão das tentativas e comprovações experimentais quanto ao constructo "locus de controle " e à reação à frustração. A verificação empírica do modelo aqui proposto ' consistiu numa pesquisa piloto apta a comprovar, sob alguns aspectos, a relação entre a variável "locus de controle" e a tolerância à frustração. Paralelamente foi possível examinar o papel da variável "formação universitária". Utilizou-se um grupo de estudante e universitários e os resultados ' indicaram que, sujeitos com "locus interno" apresentam um nível mais amadurecido de tolerância à frustração por revelarem maior persistência .em seus objetivos e capacidade de iniciativa em situação frustrante. Quanto ao tipo de formação universitária. estudantes de pedagogia mostraram-se mais intrapunitivos que estudantes de outras áreas independentemente da direção do "locus de controle”. Um exame da influência do tipo de situação frustradora permitiu concluir que "circunstâncias que envolvem "ameaça do eu" levam a uma descarga emocional do tipo culpa em detrimento da iniciativa e aquelas situações em que o sujeito e bloqueado em um objetivo ressaltam as reações extra punitivas.

Expressão e percepção dos sentimentos de amor e desamor na vivencia da díade amorosa

Esta pesquisa teve como objetivo tornar explícita a vivência do sentimento de amor e desamor da díade amorosa de um grupo de pessoas, através de uma abordagem existencial fenômeno lógica. Caracterizou-se por uma pesquisa exploratória de campo que apreendeu os relatos de histórias já vividas por 69 pessoas, mulheres e homens, universitários dos cursos de Educação Física, Engenharia e Filosofia, tendo a maioria a idade de 22 e 23 anos. Com pressupostos da técnica dos Incidentes Críticos norteando uma entrevista, procurou-se captar como as pessoas expressam e percebem o sentimento de amor e desamor em relação ao companheiro(a) da díade amorosa. O sentimento de amor foi expresso por ações tais como "Declarar", "Acarinhar", "Presentear", "Confiar", "Ceder", "Mostrar interesse" através de "ajudar em momentos difíceis", "Apoiar/Preocupar", Acolher", "Procurar o outro" e "Querer estar junto". O sentimento de desamor foi apreendido como “Agredir", "Terminar o relacionamento", "Ser egoísta", "Mostrar desinteresse", através da "Indiferença, mostrar-se frio e distante", "Desatenção/Indelicadeza", "Ter outros interesses em momentos de lazer que não estar com a pessoa", "Interessar-se amorosamente por outra pessoa" e "Mostrar dúvidas". Pela análise efetuada observa-se que homens e mulheres não possuem diferenças significativas no número dos relatos por categorias. No entanto homens apresentaram maior proporção de relatos de amor em "Acarinhar" e "Presentear" e as mulheres em "Confiar" e "Ceder". Foram levantadas também as definições pessoais de amor e desamor e os indícios autoperceptivos do estar amando, encontrando-se alguma correspondência com as categorias vivenciais. Nenhuma diferença significativa foi encontrada em termos de proporção e conteúdo entre as pessoas pertencentes aos diversos cursos.
