Measuring university-to-work success: development of a new scale

Purpose – The purpose of this paper is to develop a subjective multidimensional measure of early career success during university-to-work transition. Design/methodology/approach – The construct of university-to-work success (UWS) was defined in terms of intrinsic and extrinsic career outcomes, and a three-stage study was conducted to create a new scale. Findings – A preliminary set of items was developed and tested by judges. Results showed the items had good content validity. Factor analyses indicated a four-factor structure and a second-order model with subscales to assess: career insertion and satisfaction, confidence in career future, income and financial independence, and adaptation to work. Third, the authors sought to confirm the hypothesized model examining the comparative fit of the scale and two alternative models. Results showed that fits for both the first- and second-order models were acceptable. Research limitations/implications – The proposed model has sound psychometric qualities, although the validated version of the scale was not able to incorporate all constructs envisaged by the initial theoretical model. Results indicated some direction for further refinement. Practical implications – The scale could be used as a tool for self-assessment or as an outcome measure to assess the efficacy of university-to-work programs in applied settings. Originality/value – This study provides a useful single measure to assess early career success during the university-to-work transition, and might facilitate testing of causal models which could help identify factors relevant for successful transition.

Spousal support and satisfaction with healthcare services as moderators between psychological morbidity and adherence to diet in Type 2 Diabetes patients

Objectives: This study analyzed the moderating role of partners’ support and satisfaction with healthcare services in the relationship between psychological morbidity and adherence to diet in patients with type 2 diabetes (T2DM). Methods: Participants were 387 recently diagnosed T2DM patients that answered the following instruments: Revised Summary of Diabetes Self- Care Activities Measure, Hospital Anxiety and Depression Scales, Multidimensional Diabetes Questionnaire and Patient Satisfaction Questionnaire. Results: Partners’ positive and negative support moderated the relationship between psychological morbidity and adherence to diet. Satisfaction with healthcare services also moderated the relationship between psychological morbidity and adherence to diet. Conclusions: Intervention programs to promote adherence to diet in patients with type 2 diabetes should focus on partners’ support and patient satisfaction with healthcare services.

Recurrence relations for Clifford algebra-valued orthogonal polynomials

The theory of orthogonal polynomials of one real or complex variable is well established as well as its generalization for the multidimensional case. Hypercomplex function theory (or Clifford analysis) provides an alternative approach to deal with higher dimensions. In this context, we study systems of orthogonal polynomials of a hypercomplex variable with values in a Clifford algebra and prove some of their properties.

Aprender a ser un recurso humano útil: crítica desde la perspectiva gelpiana

Gelpi adopta un concepto amplio y multidimensional de la educación permanente, en el que integra, entre otras, la educación de jóvenes y adultos. Para el autor, la educación permanente es en simultáneo, “[…] un concepto, una política, una práctica, un objetivo, un método”, comprendiendo la educación formal, no formal, la autoformación y el aprendizaje institucional, la educación a distancia y la educación presencial, la formación inicial y la formación continua, estando presente en todas las edades, tiempos y lugares, en el trabajo y en el no-trabajo (Gelpi, 1998: 125). Debería, por lo demás, entenderse no como una definición estable, más o menos cristalizada, sino como una realidad en permanente mutación – al igual que el mundo social -, hasta para conseguir evitar que la naturaleza “revolucionaria” del principio de la educación permanente pudiese venir a quedar reducido a un campo de prácticas “conservadoras” y meramente utilitaristas, coartado por agencias, gobiernos y empresas de una forma ambigua o incluso reduccionista (Id., ibid.: 125-126). Esta advertencia representa bien el eje de la concepción gelpiana de la educación permanente, por un lado de gran amplitud pero, por otro, rechazando cualquier apropiación de tipo pragmatista y fragmentario. En Gelpi, la multidimensionalidad de la educación y de la formación acepta la “pluralidad de las competencias” pero, exactamente por esta razón, rechaza verse limitada a las competencias profesionales, única forma de abrir espacio a las “competencias sociales, culturales, estéticas, efectivas y físicas que resultan indispensables para los individuos trabajadores-ciudadanos” (Gelpi, 2009: 133).

IL-17A promotes intracellular growth of Mycobacterium by inhibiting apoptosis of infected macrophages

The fate of infected macrophages is a critical aspect of immunity to mycobacteria. By depriving the pathogen of its intracellular niche, apoptotic death of the infected macrophage has been shown to be an important mechanism to control bacterial growth. Here, we show that IL-17 inhibits apoptosis of Mycobacterium bovis BCG- or Mycobacterium tuberculosis-infected macrophages thus hampering their ability to control bacterial growth. Mechanistically, we show that IL-17 inhibits p53, and impacts on the intrinsic apoptotic pathway, by increasing the Bcl2 and decreasing Bax expression, decreasing cytochrome c release from the mitochondria, and inhibiting caspase-3 activation. The same effect of IL-17 was observed in infected macrophages upon blockade of p53 nuclear translocation. These results reveal a previously unappreciated role for the IL-17/p53 axis in the regulation of mycobacteria-induced apoptosis and can have important implications in a broad spectrum of diseases where apoptosis of the infected cell is an important host defense mechanism.

Palm community transitions along a topographic gradient from floodplain to terra firme in the eastern Amazon

Palms show clear niche segregation patterns along topographic gradients in tropical forests, with some species associated to terra firme and others to seasonally flooded areas. The aim of this study was to quantitatively describe the fine-scale spatial variation within a palm community, tracking the changes in species' abundance along environmental gradients associated with a perennial stream the eastern Amazon. The study of palm communities was based on 60 forest plots in which all adult palms were counted. We found a total of 566 palms in a community containing 11 species. Furthermore, we found a significant separation in the palm community between seasonally-flooded and terra firme forests. We found a gradient with various densities of the three most abundant palm species within the first 100 m away from the flooded area. Other species were located exclusively in the terra firme forest. The abundance of the six most common species were distributed in relation to humidity gradients from floodplains to terra firme, with palm distribution from the most flood-tolerant to the least flood-tolerant palm species as follows: Euterpe oleracea, Attalea phalerata and Socratea exorrhiza (species with floodplain affinity), Astrocaryum gynacanthum, Astrocaryum aculeatum, Attalea maripa (species with terra firme affinity)

Introduction [to] Gypsy economy

‘Gypsy economy’ is a conceptual fiction as well as a matter of lived experience. First, it heuristically stabilises analytical focus on diverse economic practices of those traditionally labelled by states majorities as ‘Gypsies’ (Roma, Sinti, Travellers, peoples that identify as Gypsies, and so on). Second, it is a condensed image that makes visible recent changes in the relationship between the society, the state and the market. Ethnographic studies of Romani communities that have experienced marginalisation in relation to the dominant work ethics, informal employment and precarity for generations, but who nevertheless face their situation with self-determination and creativity that they find meaningful, therefore promises to add to the ways of thinking about human economy under the latest capitalism.

Resource partitioning and ecomorphological variation in two syntopic species of Lebiasinidae (Characiformes) in an Amazonian stream

ABSTRACTResource partitioning is important for species coexistence. Species with similar ecomorphology are potential competitors, especially when phylogenetically close, due to niche conservatism. The aim of this study was to investigate the resource partitioning among populations of two species of lebiasinids (Copella nigrofasciata and Pyrrhulina aff. brevis) that co-occur in a first-order Amazonian stream, analyzing the trophic ecology, feeding strategies and ecomorphological attributes related to the use of food and space by these species. Fish were captured in May and September 2010. The stomach contents of 60 individuals were analyzed and quantified volumetrically to characterize the feeding ecology of both species. Eleven morphological attributes were measured in 20 specimens and combined in nine ecomorphological indices. Both species had an omnivorous-invertivorous diet and consumed predominantly allochthonous items. Both showed a tendency to a generalist diet, but intrapopulational variation in resource use was also detected. Overall feeding niche overlap was high, but differed between seasons: low during the rainy season and high in the dry season. In the latter, the food niche overlap was asymmetric because C. nigrofasciata consumed several prey of P. aff. brevis, which reduced its food spectrum. The ecomorphological analysis suggests that C. nigrofasciatahas greater swimming capacity (greater relative length of caudal peduncle) than P. aff. brevis, which has greater maneuverability and tendency to inhabit lentic environments (greater relative depth of the body). Our results demonstrate that these species have similar trophic ecology and suggest a spatial segregation, given by morphological differences related to locomotion and occupation of habitat, favoring their coexistence.

Floristic and structure of an Amazonian primary forest and a chronosequence of secondary succession

ABSTRACT The analysis of changes in species composition and vegetation structure in chronosequences improves knowledge on the regeneration patterns following land abandonment in the Amazon. Here, the objective was to perform floristic-structural analysis in mature forests (with/without timber exploitation) and secondary successions (initial, intermediate and advanced vegetation regrowth) in the Tapajós region. The regrowth age and plot locations were determined using Landsat-5/Thematic Mapper images (1984-2012). For floristic analysis, we determined the sample sufficiency and the Shannon-Weaver (H'), Pielou evenness (J), Value of Importance (VI) and Fisher's alpha (α) indices. We applied the Non-metric Multidimensional Scaling (NMDS) for similarity ordination. For structural analysis, the diameter at the breast height (DBH), total tree height (Ht), basal area (BA) and the aboveground biomass (AGB) were obtained. We inspected the differences in floristic-structural attributes using Tukey and Kolmogorov-Smirnov tests. The results showed an increase in the H', J and α indices from initial regrowth to mature forests of the order of 47%, 33% and 91%, respectively. The advanced regrowth had more species in common with the intermediate stage than with the mature forest. Statistically significant differences between initial and intermediate stages (p<0.05) were observed for DBH, BA and Ht. The recovery of carbon stocks showed an AGB variation from 14.97 t ha-1 (initial regrowth) to 321.47 t ha-1 (mature forests). In addition to AGB, Ht was also important to discriminate the typologies.

Biomimetic strategies to engineer mineralised human tissues

In the last few years, many reports have been describing promising biocompatible and biodegradable materials that can mimic in a certain extent the multidimensional hierarchical structure of bone, while are also capable of releasing bioactive agents or drugs in a controlled manner. Despite these great advances, new developments in the design and fabrication technologies are required to address the need to engineer suitable biomimetic materials in order tune cells functions, i.e. enhance cell-biomaterial interactions, and promote cell adhesion, proliferation, and differentiation ability. Scaffolds, hydrogels, fibres and composite materials are the most commonly used as biomimetics for bone tissue engineering. Dynamic systems such as bioreactors have also been attracting great deal of attention as it allows developing a wide range of novel in vitro strategies for the homogeneous coating of scaffolds and prosthesis with ceramics, and production of biomimetic constructs, prior its implantation in the body. Herein, it is overviewed the biomimetic strategies for bone tissue engineering, recent developments and future trends. Conventional and more recent processing methodologies are also described.

Craving e dependência química: conceito, avaliação e tratamento

O craving ou fissura, cuja definição mais comum é o desejo intenso por uma substância, é um conceito controverso entre os pesquisadores da área da dependência química. OBJETIVO: Realizar revisão teórica a respeito do craving nos bancos de dados PsycInfo, Medline, ProQuest e Science Direct. MÉTODO: As palavras-chave utilizadas foram craving, dependence e drug e o período pesquisado foi entre 1995 e 2007. RESULTADOS: Os resultados demonstraram que são encontrados diversos significados para o craving, alguns se restringindo a desejo, e outros, considerando-o não só como desejo, mas como antecipação do resultado positivo do uso da substância, alívio dos sintomas de abstinência ou afeto negativo e intenção de fumar, o que reflete uma visão multidimensional deste construto. A etiologia do craving pode ser explicada por intermédio dos modelos: comportamental, cognitivo ou psicossocial e neurobiológico, porquanto a opção por um destes influencia a avaliação e o manejo. CONCLUSÃO: Conclui-se quanto à multidimensionalidade do craving e quanto à necessidade de que seja utilizado um modelo biopsicossocial que integre os diversos modelos no tratamento de dependentes químicos. Destaca-se a importância da realização de mais estudos para a compreensão do craving em função deste ser um dos principais riscos de recaída.

Fatores associados à sintomatologia depressiva numa coorte urbana de idosos

OBJETIVO: Analisar a associação, em uma coorte urbana de idosos, entre sintomatologia depressiva e outros indicadores de capacidade funcional com a mortalidade após 15 anos de seguimento. MÉTODOS: Foram estudados os casos de 1.667 idosos (> 65 anos) residentes em Vila Clementino, na cidade de São Paulo, por meio de uma avaliação multidimensional da capacidade funcional e dos atestados de óbito referentes a mortes ocorridas entre 1991 (início do estudo) e abril de 2006. Na análise univariada foram calculadas as razões de chances e sua significância estatística foi avaliada pelo intervalo de confiança (95%). Na análise múltipla foi empregada a regressão logística. RESULTADOS: Entre os idosos estudados, 21,1% eram deprimidos em 1991. Na análise univariada, as maiores proporções de deprimidos foram observadas entre indivíduos do sexo feminino, com mais de 80 anos, analfabetos, viúvos ou solteiros, com alto nível de dependência física e de déficit cognitivo, usuários de mais medicamentos e entre os que morreram no período de seguimento de 15 anos. Na análise múltipla, controlando-se por sexo e idade, a presença de dependência física e o fato de ser usuário de mais medicamentos foram os principais preditores da ocorrência de depressão. CONCLUSÕES: A ocorrência de sintomatologia depressiva parece estar diretamente relacionada aos níveis de incapacidade física observados entre os idosos.
