Diferencias intra e inter individuales en inteligencia social de estudiantes portugueses
Social intelligence is a favorable condition for career decision-making and development. The social intelligence indices
of Portuguese students in school years prior to a career transition are characterized and intra and interindividual differences are
analyzed. Participants were 1095 students (552, 50.4% women) with a mean age of 14.78 years (SD = 1.86), in the 8th (542,
49.5%), 10th (295, 26.9%) and 11th (258, 23.6%) grades. The Cognitive Test of Social Intelligence (PCIS) was administered at
two moments, six months apart. Results indicate that the 8th grade obtained higher average scores in Problem Solving, Motivation
and Self-confidence (time 1), while the 10th grade obtained better results in Problem Solving, Motivation and Familiarity (time 2).
Between the assessment moments, all school years register an increase in Problem Solving and Self-confidence in social situations.
These results constitute favorable psychological conditions for the promotion of ethical questioning in career guidance interventions.A inteligência social constitui uma condição favorável à tomada de decisão e ao desenvolvimento vocacional.
Este trabalho visa caracterizar os níveis de inteligência social, e analisar as diferenças intra e interindividuais, em alunos
portugueses em anos de pré-transição vocacional. Participaram 1095 alunos (552, 50% mulheres), com uma média de idades
de 14,78 anos (DP = 1,86), do 8º, 10º, e 11º níveis escolares. Administrou-se a Prova Cognitiva de Inteligência Social (PCIS),
em dois momentos (T1 e T2), com seis meses de intervalo. Os resultados indicam que o 8º ano obteve resultados médios
superiores, nos índices de Resolução de Problemas, Motivação e Autoconfiança (T1), enquanto o 10º ano obteve resultados
superiores, em Resolução de Problemas, Motivação e Familiaridade (T2). Entre momentos de avaliação, registra-se, para
todos os níveis escolares, um aumento em Resolução de Problemas e Autoconfiança em situações sociais. Estes resultados
constituem condições psicológicas favoráveis à promoção do questionamento ético nas intervenções de orientação vocacional.La inteligencia social es una condición favorable para la toma de decisiones y el desarrollo de la carrera. Se

Valores como predictores de satisfacción con la vida en los jóvenes
Numa perspectiva funcionalista, os valores são uma expressão cognitiva das necessidades humanas, princípios que orientam o comportamento para metas mais pessoais, sociais ou gerais de vida, cujo impacto psicossocial merece mais investigação. Neste estudo, analisou-se em que medida o tipo de orientação dos valores prediz a satisfação com a vida de 562 jovens portugueses (n = 303, 53,9% mulheres), com idades entre 14 e 22 anos (M = 16,9, DP = 1,71), que frequentam o ensino médio: via profissionalizante (63,7%) e regular (36,3%). Os jovens completaram o Questionário de Valores Básicos e a Escala de Satisfação com a Vida. Os resultados da análise de regressão linear indicam que a orientação dos valores explica menos de um quarto da variabilidade da satisfação com a vida, o que suscita a necessidade de se analisar o seu poder explicativo em conjunto com outras variáveis, por exemplo, de personalidade e sociocognitivas.In a functionalist perspective, values are a cognitive expression of human needs as well as principles that guide behaviors to personal, social or general life goals, whose psychosocial impact deserves more investigation. This study aimed to analyze whether the type of values orientation predicts life satisfaction in 562 Portuguese youths (n = 303, 53.9% women) aged 14 to 22 years (M = 16.9; SD = 1.71), attending high school studies, being 63.7% technical and (36.3%) regular high school.Students completed the Basic Values Survey and the Satisfaction With Life Scale. The results of the linear regression analyzes indicate that the values orientation explains less than a quarter of life satisfaction variability, which indicated the need to further analyze its explanatory power together with other variables, such as, personality and socio-cognitive.Desde el punto de vista funcional, los valores son una expresión cognitiva de las necesidades humanas, principios que orientan el comportamiento hacia metas más personales, sociales o generales de vida, cuyo impacto psicosocial necesita más investigación.

Career self: a longitudinal study with college students
O self de carreira constituí um subconjunto organizado do universo cognitivo de uma pessoa, responsável pelo carácter subjetivo que a mesma confere à carreira. Este estudo pretende avaliar mudanças no conteúdo do self de carreira
de estudantes universitários, do início para o final do último ano de graduação. Para tal, recorreu-se a medidas repetidas dos
índices da Grelha de Repertório da Carreira (Silva & Taveira, 2005; Silva, 2008). Na investigação, participaram 80 estudantes, dos quais 49 são mulheres (61,25%) e 31 são homens (38,75%), com idades entre os 21 e os 45 anos (M= 23,9, DP= 4,31).
Os resultados indicam que, no final da licenciatura, os estudantes diminuem a distância como se constrõem em relação aos outros e mantêm uma construção positiva do self de carreira.Fundação para a Ciência e a Tecnologia (FCT
Psychologists’ dilemmas in career counselling practice
In this study, we explored main dilemmas psychologists face in career
counselling in two main professional settings: employment and education. Participants
included 24 experienced Portuguese psychologists, working in employment
(n = 14) and educational (n = 10) settings. We used consensual qualitative
research to conduct and analyse semi-structured interviews. Results revealed
dilemmas’ in five domains: neutrality, assessment, dual loyalty, role boundaries, and
confidentiality, with the typical dilemma in the domain of neutrality. Differences
between groups were found in the domains of dual loyalty and role boundaries.Dans cette étude, nous avons exploré les principaux dilemmes rencontrés
par les psychologues dans le conseil en orientation dans deux milieux professionnels
centraux: le placement et l’éducation. Parmi les participants figuraient 24 psychologues
portugais expérimentés travaillant dans des contextes de placement (n = 14)
et d’éducation (n = 10). Nous avons utilisé la recherche qualitative consensuelle
pour mener et analyser les entretiens semi-structurés. Les re´sultats ont révé lé des
dilemmes dans cinq domaines: la neutralité, l’évaluation, la double loyauté, les
limites du rôle, et la confidentialité, avec le dilemme typique dans le domaine de la
neutralité. Les différences entre les groupes ont été identifiees dans les domaines de
la double loyauté et les limites du rôle.In dieser Studie untersuchten wir die hauptsä chlichen Dilemmata, mit denen Psychologen in der Berufsberatung in zwei wesentlichen professionellen
Einrichtungen konfrontiert sind: Beruf und Bildung. Zu den Teilnehmern geho
¨rten 24 erfahrene portugiesische Psychologen, die in Einrichtungen von Beruf
(n = 14) und Bildung (n = 10) arbeiteten. Wir verwendeten einvernehmliche
qualitative Forschung um semi-strukturierte Interviews durchzufu¨hren und zu
analysieren. Die Ergebnisse zeigten Dilemmata in fünf Bereichen: Neutralität,
Beurteilung, doppelte Loyalität, Rollengrenzen und Vertraulichkeit, mit dem
typischen Dilemma in der Domäne der Neutralität. Unterschiede zwischen den
Gruppen wurden in den Bereichen der doppelten Loyalität und Rollengrenzen
gefunden

CC BY Licence: http://creativecommons.org/licenses/by/4.0/Background: CRF14_BG isolates, originally found in Spain, are characterized by CXCR4 tropism and rapid disease
progression. This study aimed to identify the origin of CRF14_BG and reconstruct its epidemiological history based on new
isolates from Portugal.Methodology/Principal Findings: C2V3C3 env gene sequences were obtained from 62 samples collected in 1993–1998
from Portuguese HIV-1 patients. Full-length genomic sequences were obtained from three patients. Viral subtypes, diversity,
divergence rate and positive selection were investigated by phylogenetic analysis. The molecular structure of the genomes
was determined by bootscanning. A relaxed molecular clock model was used to date the origin of CRF14_BG. Geno2pheno
was used to predict viral tropism. Subtype B was the most prevalent subtype (45 sequences; 73%) followed by CRF14_BG (8;
13%), G (4; 6%), F1 (2; 3%), C (2; 3%) and CRF02_AG (1; 2%). Three CRF14_BG sequences were derived from 1993 samples.
Near full-length genomic sequences were strongly related to the CRF14_BG isolates from Spain. Genetic diversity of the
Portuguese isolates was significantly higher than the Spanish isolates (0.044 vs 0.014, P,0.0001). The mean date of origin of
the CRF14_BG cluster was estimated to be 1992 (range, 1989 and 1996) based on the subtype G genomic region and 1989
(range, 1984–1993) based on the subtype B genomic region. Most CRF14_BG strains (78.9%) were predicted to be CXCR4.
Finally, up to five amino acids were under selective pressure in subtype B V3 loop whereas only one was found in the
CRF14_BG cluster.Conclusions: CRF14_BG emerged in Portugal in the early 1990 s soon after the beginning of the HIV-1 epidemics, spread to
Spain in late 1990 s as a consequence of IVDUs migration and then to the rest of Europe. CXCR4 tropism is a general
characteristic of this CRF that may have been selected for by escape from neutralizing antibody response
