A GIS extension model to calculate urban heat island intensity based on urban geometry

This paper presents a simulation model, which was incorporated into a Geographic Information System (GIS), in order to calculate the maximum intensity of urban heat islands based on urban geometry data. The method-ology of this study stands on a theoretical-numerical basis (Okeâ s model), followed by the study and selection of existing GIS tools, the design of the calculation model, the incorporation of the resulting algorithm into the GIS platform and the application of the tool, developed as exemplification. The developed tool will help researchers to simulate UHI in different urban scenarios.

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.

Further results on the inverse along an element in semigroups and rings

In this paper, we introduce a new notion in a semigroup $S$ as an extension of Mary's inverse. Let $a,d\in S$. An element $a$ is called left (resp. right) invertible along $d$ if there exists $b\in S$ such that $bad=d$ (resp. $dab=b$) and $b\leq_\mathcal{L}d$ (resp. $b\leq_\mathcal{R}d$). An existence criterion of this type inverse is derived. Moreover, several characterizations of left (right) regularity, left (right) $\pi$-regularity and left (right) $*$-regularity are given in a semigroup. Further, another existence criterion of this type inverse is given by means of a left (right) invertibility of certain elements in a ring. Finally we study the (left, right) inverse along a product in a ring, and, as an application, Mary's inverse along a matrix is expressed.

Versão portuguesa das “Escalas de Táticas de Conflito Revisadas”: estudo de validação

As escalas de Táticas de Conflito Revisadas (CTS2) destinam-se a avaliar o modo como os casais resolvem os seus conflitos, através de estratégias de negociação ou de abuso: (a) abuso físico sem sequelas; (b) agressão psicológica; (c) abuso físico com sequelas; (d) coerção sexual. A versão portuguesa foi administrada a uma amostra de 551 estudantes universitários (332 do sexo feminino), 45 dos quais têm uma relação íntima entre si. Considera os cinco factores propostos pelos autores das escalas originais e apresenta valores de consistência interna compreendidos entre .78 e .50. As correlações entre os diferentes tipos de abuso e a desejabilidade social, história de socialização violenta, crime violento, domínio na relação, e ainda a concordância nos heterorrelatos de ambos elementos da díade, testemunham a validade das escalas. Investigadores e técnicos da psicologia e áreas afins têm agora à sua disposição a versão portuguesa das CTS2, que tem demonstrado elevada aplicabilidade na determinação da presença de relações abusivas no seio da família, na avaliação da eficácia de programas de intervenção no contexto forense e em estudos de cariz epidemiológico.
