Análisis del «perfil» de estudiantes de Enfermería mediante el test de Cattel

Conocer cuál es la personalidad de aquellos que acceden a nuestras Escuelas y que en pocos años se convertirán en futuros profesionales de Enfermería, ha sido el objetivo de un estudio llevado a cabo por la Comisión de Docencia de la E.U.E. de Barcelona. En él se realiza un análisis comparativo de los perfiles de personalidad de los estudiantes admitidos en la E.U.E. de Barcelona y los candidatos pre-inscritos en dicha escuela en 1983, frente a estudiantes de Enfermería americanas y británicas y los candidatos a estudiantes de Medicina de la Universidad de Navarra.

Perfil sócio-econômico dos alunos, repetência e evasão no curso de Química da UFMG

This paper describes a study about the causes for the dropout of chemistry undergraduate students at UFMG in the nineties. The students' social and economic profile was outlined. It was observed a correlation between family income and academic performance and between failure at the beginning of the course and the dropout, but it seems that family income doesn't affect markedly the dropout. The endogenous and exogenous causes contribute equally for the dropout. The authors suggest that the dropout could be significantly reduced if the endogenous causes such as large classes, inadequate curricula and programmes, poor teaching and the unapproachability on the part of the teachers were faced.

O perfil profissional do químico frente às novas realidades das organizações industriais

The objective of this paper is to reflect about the professional profile required of chemists by the chemical industry employing new management practices. This paper includes: a) historical synthesis of the appropriation of chemical knowledge by the industrial sector, b) a discussion of today's industrial organization and a comparison between the professional profile of chemists as expected by the taylorist and fordist standards of production and that expected in the context of flexibilization and globalization of production.

Técnicas de análise do perfil de execução e otimização de programas em química computacional

In this paper we review the basic techniques of performance analysis within the UNIX environment that are relevant in computational chemistry, with particular emphasis on the execution profile using the gprof tool. Two case studies (in ab initio and molecular dynamics calculations) are presented in order to illustrate how execution profiling can be used to effectively identify bottlenecks and to guide source code optimization. Using these profiling and optimization techniques it was possible to obtain significant speedups (of up to 30%) in both cases.

Perfil cromatográfico de duas espécies de Plumbaginaceae: Plumbago scandens L. E Plumbago auriculata Lam

The genus Plumbago belongs to the family Plumbaginaceae, order Plumbaginales. Comparative chemical profile of P. scandens (native) and P. auriculata (cultivated) was obtained by normal and reversed-phase high performance liquid chromatography with photodiode array detector. Comparison of the ultraviolet espectra and the retention times for the compounds allowed to find similar metabolic patterns in roots, stems and leaves. Four flavonoids, one phenolic acid or derivative and the naphtoquinone plumbagin were comparatively identified to standards.

Semicarbazonas e tiossemicarbazonas: o amplo perfil farmacológico e usos clínicos

This article shows that thiosemicarbazones, semicarbazones and their metal complexes can exhibit target selectivity along with a wide pharmacological profile. Complexes of thiosemicarbazones with cytotoxic or antitumoral activity are presented, some of which show activity against cisplatinum-resistant cells. The inhibition mechanism of the enzyme ribonucleoside diphosphate reductase (RDR), involved in DNA syntheses, by alpha(N)-heterocyclic thiosemicarbazones is discussed. The encouraging results of clinical trials with the RDR inhibitor 3-aminopyridine-2-carboxaldehyde thiosemicarbazone ("Triapine") against rapidly growing tumors are outlined. Examples are also given of thiosemicarbazones with antiviral and antimicrobial activity. The possible applications of semicarbazones as anticonvulsants with low toxicity and good therapeutic index are presented.

El sistema competencial español a la luz de la eficiencia: indefinición, duplicidades, vulnerabilidad de las competencias autonómicas y conflictividad

La crisis financiera y la crisis de la deuda soberana han tenido un gran impacto en el Estado autonómico y han polarizado las posiciones entre los partidarios de una mayor centralización y los que consideran agotado el modelo autonómico y defienden la necesidad de articular nuevas vías para alcanzar y garantizar el nivel de autogobierno. En este análisis se argumenta que a pesar de que la crisis ha tenido un impacto negativo en el debate sobre la viabilidad del Estado autonómico y en la percepción ciudadana sobre el nivel de gasto y de competencias de las Comunidades Autónomas este debate es anterior a la crisis económica. Además la crisis ha tenido un mayor impacto en estados de estructura unitaria o poco descentralizada, y menor en estados de estructura federal, por lo que no parece que exista una relación directa entre descentralización y crisis económica.

Determinação do perfil de compostos voláteis e avaliação do sabor e aroma de bebidas produzidas a partir da erva-mate (Ilex paraguariensis)

Volatile compounds from green and roasted yerba mate were analyzed by gas chromatography/mass spectrometry and the flavor profile from yerba mate beverages was determined by descriptive quantitative analyses. The main compounds tentatively identified in green mate were linalool, alpha-terpineol and trans-linalool oxide and in roasted mate were (E,Z)-2,4-heptadienal isomers and 5-methylfurfural. Green mate infusion was qualified as having bitter taste and aroma as well as green grass aroma while roasted mate was defined as having a smooth, slightly burnt aroma. The relationship between the tentatively identified compounds and flavor must be determined by olfatometric analysis.

Perfil Clínico de Apego (PCA): Elaboración de un sistema de categorías para la evaluación del apego

A partir de la teoría de Bowlby y de los estilos de apego propuestos por Bartholomew y Horowitz, se desarrolla el Perfil Clínico de Apego-narrativas (PCA-n), un sistema de observación para evaluar el apego a partir de las narrativas de los y las pacientes. En el Estudio 1, se construye una primera versión del instrumento (PCAv1). La consistencia interna resulta adecuada en la evaluación del apego seguro y evitativo, pero insuficiente en el caso del apego preocupado y temeroso. En el Estudio 2 se introducen cambios en el instrumento (PCA-n), que finalmente consta de cuatro categorías: disponibilidad-confianza, autonomía en la relación, regulación de las emociones y revelación de las emociones. Aplicado a las narrativas de dos pacientes, se obtiene un nivel de acuerdo entre evaluadores en la identificación de las narrativas significativas superior al 75%. También resulta adecuada la fiabilidad del PCA-n, ya que la correlación promedio en la identificación de las categorías fue .78 en el caso del paciente 1, y .88 en el paciente 2.Se discuten las aplicaciones posibles del PCA-n, sus ventajas y limitaciones, así como líneas de investigación futuras.

Perfil de leitores em um curso de licenciatura em química

The purpose of this study is to investigate the reading practice of undergraduate students of Chemistry, in a State University in Brazil. More specifically, we aim at showing students' habits and experiences concerning reading. Our research questions were: 1) What is the profile of readers in an undergraduate Chemistry course? 2) What can be perceived concerning students' reading experience? Results show that students' beliefs and practices are contradictory; although reading is considered by them as fundamental, they do not seem to have solid reading habits. This points to the necessity of rediscussing some aspects of Chemistry teacher formation.

Estudi sobre el perfil de persones grans amb dependència del servei d'ajuda a domicili del Consell Comarcal d'Osona i el tipus de suport formal i informal

The aim of this study is to determine the profile of dependent elderly people users of the home care services (SAD) of the regional council in Osona (Consell Comarcal d´Osona) , and the characteristics of formal and informal types of support they use. Methodology. An observational study of a transversal format has been carried out, with retrospective and descriptive purposes. The target population is 63 people (26 men and 37 women) included in the program of the regional SAD They have a recognized dependence grade approved by the law 39 /2006, December 14th , promoting the individual autonomy and care of elderly people in a dependent situation. The data were collected by social workers of basic social services, first with a home visit and followed by handed out questionnaires, specifically designed for this study, in order to obtain information on socio-demographic characteristics, and the type of support formal and informal. The obtained results on the SAD users are women in a 58.7% and a 41.3 % are men. The 84% of the total sampling are 80 years old and more, being the average age of 85.2 years old. 45% of them are married, 41% are widows and widowers and 14% are single. 54% are rated with severe dependence (grade II), 42.8% with high dependence (grade III). 86% live accompanied. 100% have an informal caregiver and a 95% of the times, the caregiver is a relative who in 73% of the cases the dedication time is permanent. The coverage of the SAD has an average of 4.27 hours per week and per user. The formal services most used are the technical (62%), also the assessment of an occupational therapist at home (57%) and the telecare service in a (56%). Conclusions. The SAD is used primarily for women in an advanced age and severe dependence. The informal assistance structures have an informal caregiver, being a member of the family mostly, living with the dependent, and mainly in a permanent dedication basis. The SAD has a varied intensity in each case. The formal support services complementary to the SAD, are largely used in all cases.
