Could time detect a faking-good attitude? A study with the MMPI-2-RF

Background and Purpose: Research on the relationship between response latency (RL) and faking in self-administered testing scenarios have generated contradictory findings. We explored this relationship further, aiming to add further insight into the reliability of self-report measures. We compared RLs and T-scores on the MMPI-2-RF (validity and restructured clinical [RC] scales) in four experimental groups. Our hypotheses were that: the Fake-Good Speeded group would obtain a different completion time; show higher RLs than the Honesty Speeded Group in the validity scales; show higher T-Scores in the L-r and K-r scales and lower T-scores in the F-r and RC scales; and show higher levels of tension and fatigue. Finally, the impact of the speeded condition in malingering was assessed. Materials and Methods: The sample was comprised of 135 subjects (M = 26.64; SD = 1.88 years old), all of whom were graduates (having completed at least 17 years of instruction), male, and Caucasian. Subjects were randomly assigned to four groups: Honesty Speeded, Fake-Good Speeded, Honesty Un-Speeded, and Fake-Good Un-Speeded. A software version of the MMPI-2-RF and Visual Analog Scale (VAS) were administered. To test the hypotheses, MANOVAs and binomial logistic regressions were run. Results: Significant differences were found between the four groups, and particularly between the Honest and Fake-Good groups in terms of test completion time and the L-r and K-r scales. The speeded condition increased T-scores in the L-r and K-r scales but decreased T-scores in some of the RC scales. The Fake groups also scored higher on the VAS Tension subscale. Completion times for the first and second parts of the MMPI-2-RF and T-scores for the K-r scale seemed to predict malingering. Conclusion: The speeded condition seemed to bring out the malingerers. Limitations include the sample size and gender bias

Used food oils: physical-chemical indicators of quality degradation

Comunicação apresentada em 11th Baltic Conference on Food Science and Technology “Food science and technology in achanging world” FOODBALT 2017 Conference Proceedings. Jelgava, LLUUsed food oil (UFO), designated as frying oil, is a residue. Degradation by reuse or during storage, may occur by contacting, chemical, enzymatic and microbiological pathways, but oxidation is a major concern of the industry, as it affects sensory and nutritional quality of edible oils, with potentially toxic compounds formation. In Portugal, UFO's main destination still is the sewerage system, an environmental problem and waste of raw material, which can be re-qualified for non-food uses. However, quality control applied to UFO's, often results into expensive analysis inappropriate for small laboratories and catering industry. This project, developed with the Musketeers Group Portugal co-promotion (2012-2016), aimed to identify low-cost physicochemical parameters for further implementation as UFO's Quality Degradation Indicators (QDI) indicating defects quickly and accurately. UFO's analysis was tested on the use, for industrial frying, and by degradation induced in the laboratory (frying and heat stability tests) by applying following parameters: moisture, water activity (a(w)), total acidity, peroxide index, iodine index, colour (CIE, CIE Lab), UV absorbency, total polar compounds and microbiological indicators. Internal procedures (ESAS) were validated, redefining working ranges and test conditions, as standards procedures did not provide reliable results for the entire life cycle of oils, whose profile changes with time and reuse. Results demonstrate significant differences with quick response parameters as Total Acidity, Peroxide Index and CIE Lab colour, outlined as QDI's. Moisture, aw and CIE Lab colour proved to be inadequate for this purpose. Iodine Index and UV Absorbency are more complex and time-consuming and were profiled as reference methods.info:eu-repo/semantics/publishedVersio

John Maynard Keynes: The Economist as Investor

John Maynard Keynes: The Economist as Investor Abstract Keynes the investor has recently attracted the attention of several scholars and quite a few articles have come out in the last five years. A description of Keynes’s dealings has emerged, assessing his performance as an investor as superior but not as stellar as had previously been believed. However, overall evaluation of Keynes’s performance is still lacking. This paper contributes to this growing literature by filling some of the gaps, especially in relation to Keynes’s investment philosophy and economic theory, and by undertaking a more comprehensive review of the available evidence, drawing on some unpublished sources which have not as yet been fully exploite

“Música em PAS”: music as an evaluation object of the program of serial university entrance examination of University of Brasília (PAS/UnB)

This paper discusses the musical proposal to Program of Serial University Entrance Examination of University of Brasília (PAS/UnB). The discussion is based on author’s participation on elaboration, systematization, and review groups of 2001 and 2006 programs, as well her researches and her teacher training activities with PAS. The text presents the program, its evaluation conception and the music-pedagogical principles and purposes that guide the insertion of musical knowledge as compulsory evaluation’s object in the university entrance examination. The last program’s version has adopted an Evaluation’s Matrix with some music competences, abilities and evaluation’s objects. The development of music’s competences and abilities is oriented by a music repertoire that defi- nes the content and should be a way for development of musical practices and experiences (performance, improvisation and composition), reception (musical appraising) and context. In this process, the schools and its music teachers are responsible for create learning and teaching situations where the musical experience could be celebrated in sense of to promote a musical significant learning experience and the student’s success in PAS/UnB exams

Metformin Treatment Modulates The Tumour-induced Wasting Effects In Muscle Protein Metabolism Minimising The Cachexia In Tumour-bearing Rats

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Cancer-cachexia state frequently induces both fat and protein wasting, leading to death. In this way, the knowledge of the mechanism of drugs and their side effects can be a new feature to treat and to have success, contributing to a better life quality for these patients. Metformin is an oral drug used in type 2 diabetes mellitus, showing inhibitory effect on proliferation in some neoplastic cells. For this reason, we evaluated its modulatory effect on Walker-256 tumour evolution and also on protein metabolism in gastrocnemius muscle and body composition. Methods: Wistar rats received or not tumour implant and metformin treatment and were distributed into four groups, as followed: control (C), Walker 256 tumour-bearing (W), metformin-treated (M) and tumour-bearing treated with metformin (WM). Animals were weighed three times a week, and after cachexia state has been detected, the rats were euthanised and muscle and tumour excised and analysed by biochemical and molecular assays. Results: Tumour growth promoted some deleterious effects on chemical body composition, increasing water and decreasing fat percentage, and reducing lean body mass. In muscle tissue, tumour led to a decreased protein synthesis and an increased proteolysis, showing the higher activity of the ubiquitin-proteasome pathway. On the other hand, the metformin treatment likely minimised the tumour-induced wasting state; in this way, this treatment ameliorated chemical body composition, reduced the higher activities of proteolytic enzymes and decreased the protein waste. Conclusion: Metformin treatment not only decreases the tumour growth but also improves the protein metabolism in gastrocnemius muscle in tumour-bearing rats.16Fundacao de Amparo a Pesquisa do Estado de Sao Paulo - FAPESP [2010/00209-9, 2013/16115-1, 2014/13334-7]Conselho Nacional de Desenvolvimento Cientifico e Tecnologico - CNPq [304604/2010-0, 302863/2013-3]Fundacao de Amparo a Pesquisa do Estado de Sao Paulo - FAPESP, Sao Paulo, Brazil [2008/07737-0]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Competências de gestão para a função de Enfermeiro Gestor

O conceito de competências tem sido amplamente empregado nas práticas de Gestão de Recursos Humanos. Quando outras áreas, como a Enfermagem, concilia a prestação de cuidados com a própria gestão do seu capital humano, torna-se preponderante efetuar um cruzamento dos dois mundos. Este artigo pretende identificar as competências de gestão para a função de Enfermeiro Gestor, ou seja, para aqueles que exercem funções de gestão nas organizações, com base numa revisão de literatura. Foi possível identificar 189 competências, que se agruparam nas categorias: Gestão de recursos humanos, Competências interpessoais, Organização e planeamento, Competências técnicas de enfermagem, Comunicação, Preocupação pela qualidade, Conhecimento de políticas de saúde, Resiliência e motivação, Liderança, Competências técnicas de gestão, Resolução de problemas, Iniciativa, Pensamento crítico, Tecnologias de informação e Comunicação, Ética, Adaptação à mudança, Trabalho em equipa e Autonomia. Posteriormente, efetuou-se uma comparação das competências identificadas, com um estudo de referência publicado em 2010 pelo International Council of Nurses (ICN)

Self-efficacy, mathematics’ anxiety and perceived importance: an empirical study with Portuguese engineering students

The accomplishment in mathematics has gained attention from educators and arises as an emerging field of study, including in engineering education. However, in Portugal, there is still incipient research in the area; so it is high time to explore factors that might enlighten the gap in the study of the relationship between Portuguese engineering students and the learning of mathematics. The main purpose of this study is to explore three factors identified in the literature as influencing the learning of mathematical concepts – self-efficacy, anxiety towards mathematics and perceived importance of mathematics – and search for differences by gender and by type of engineering course, a dimension not much reported in the literature but which was revealed as important in the team’s previous research. Based on a sample of 140 undergraduate students of different engineering courses from University of Minho, results only identify differences in the type of course and not in gender. These results constitute a contribution and open new paths for future research in the engineering education.FCT (Fundação para a Ciência e Tecnologia, Portugal) in the scope of the project PEst-OE/EEI/UI0319/201
