ABSTRACT This paper analyzes the role of temporary/permanent employment in the way employees respond to person-organization fit (P-O Fit) with organizational citizenship behaviors (OCBs), and whether mindfulness redraws this relationship. Compared to permanent employees, temporary employees may have fewer future prospects in their organization, thus leading them to engage less in this type of behavior, the potential returns of which are typically unspecified in time and are likely beyond their temporary reach. However, the self-regulatory, present-moment awareness and non-judgmental acceptance functions of mindfulness could reverse this relationship. Structural equation modeling using data from 280 employees of 10 Spanish hotels revealed that temporary (permanent) employees reacted to P-O Fit with lower (higher) OCBs, unless they were mindful, in which case their OCBs increased (decreased). The findings show that employment status and mindfulness redraw the P-O Fit - OCB relationship and that mindfulness makes temporary (permanent) employees respond to P-O Fit with increased (decreased) OCBs.

RESUMEN Este trabajo analiza el papel del estatus laboral temporal/permanente en la forma en que los empleados responden al ajuste persona-organización con comportamientos de ciudadanía organizacional, y si el mindfulness redibuja esta relación. En comparación con los empleados fijos, los temporales pueden tener menos perspectivas de futuro en su organización, lo que les lleva a participar menos en este tipo de comportamientos, cuyos rendimientos potenciales suelen ser indeterminados en el tiempo y probablemente están fuera de su alcance temporal. Sin embargo, las funciones de autorregulación, conciencia del momento presente y aceptación sin prejuicios del mindfulness podrían invertir esta relación. La modelización de ecuaciones estructurales con datos de 280 empleados de 10 hoteles españoles reveló que los empleados temporales (fijos) reaccionaban al ajuste persona-organización con un menor (mayor) comportamiento de ciudadanía organizacional, a menos que tuvieran mindfulness, en cuyo caso su comportamiento de ciudadanía organizacional aumentaba (disminuía). Los resultados muestran que el estatus laboral y el mindfulness redibujan la relación entre ajuste persona-organización y comportamiento de ciudadanía organizacional y que el mindfulness hace que los empleados temporales (fijos) respondan a dicho ajuste con un mayor (menor) nivel de comportamiento de ciudadanía organizacional.

Abstract INTRODUCTION: The present study investigated the association of the rs2794521 polymorphism in the CRP gene in individuals with chronic hepatitis B and C, correlating it with markers of hepatic inflammation, fibrosis scores, viral load, and plasma protein levels. METHODS: The study analyzed 185 blood samples obtained from patients with hepatitis B (n=74) and hepatitis C (n=111) and 300 samples from healthy donors. Genotyping was performed by real-time polymerase chain reaction, and protein levels were quantified using the automated immunoturbidimetric method. RESULTS: The TT genotype was the most frequent in all studied groups and was associated with higher plasma levels of the protein but not with the progression of liver disease. Low levels of C-reactive protein were associated with increased viremia and scores indicative of severe fibrosis and cirrhosis. CONCLUSIONS: The present results demonstrated a close relationship between the ability of the virus to replicate and cause liver damage and low serum concentrations of C-reactive protein. Future research may determine if these results can be interpreted as a possible form of escape for the virus by decreasing its action as an opsonin and decreasing phagocytosis, which are functions of C-reactive protein in the immune response.

INTRODUCTION: The present study investigated the prevalence of two single-nucleotide polymorphisms (SNPs) in the Toll-like receptor 3 (TLR3) gene in patients infected with hepatitis B virus (HBV) and hepatitis C virus (HCV). METHODS: Samples collected from HCV (n = 74) and HBV (n = 35) carriers were subjected to quantitative real-time PCR (qPCR) to detect the presence of the SNPs rs5743305 and rs3775291 in TLR3 and to measure the following biomarkers: alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), and prothrombin time (PT). A healthy control group was investigated and consisted of 299 HCV- and HBV-seronegative individuals. RESULTS: No significant differences in allele, genotype and haplotype frequencies were observed between the investigated groups, and no association was observed between the polymorphisms and histopathological results. Nevertheless, genotypes TA/AA (rs5743305) and GG (rs3775291) appear to be associated with higher levels of ALT (p<0.01), AST (p<0.05) and PT (p<0.05). In addition, genotypes TT (rs5743305; p<0.05) and GG (rs3775291; p<0.05) were associated with higher GGT levels. CONCLUSIONS: This genetic analysis revealed the absence of an association between the polymorphisms investigated and susceptibility to HBV and HCV infection; however, these polymorphisms might be associated with a greater degree of biliary damage during the course of HCV infection.

It is widely accepted that the consumption of ω-3 polyunsaturated fatty acids has beneficial effects on human health. In this work, ten brown macroalgae species collected along the Portuguese west coast were studied for their fatty acids composition by GC-MS after alkaline hydrolysis and derivatization. The results of this survey showed that different macroalgae from the same region display distinct fatty acids profile. Concerning ω-3 polyunsaturated fatty acids, eicosapentaenoic acid was found in all but one species. Additionally, some species contained docosahexaenoic acid. Linoleic acid, an essential fatty acid of the ω-6 series, was present in all studied macroalgae. Fucus spiralis L. exhibited the highest amounts of monounsaturated fatty acids and of polyunsaturated fatty acids of the ω-3 and ω-6 series. The ω-6/ω-3 ratio in half of the studied species was lower than 1. This information reinforces the potential application of some brown macroalgae as dietary sources of polyunsaturated fatty acids.

O Desenvolvimento Profissional (DP) tem vindo a ser revelado como um elemento crítico na formação e desempenho profissional do Psicólogo. Tendo por base os fundamentos teóricos acerca do DP e da construção da identidade profissional, e com carácter exploratório, construiu-se, implementou-se e avaliou-se a eficácia de um programa de intervenção. O principal objectivo desta é, num contexto seguro à exploração, promover o DP de estudantes de Psicologia, em duas componentes (intrapessoal e interpessoal/social). Constituíram-se dois grupos (um de 10 e outro de cinco participantes), avaliados formalmente no início e no fim do programa, através de uma medida construída para o efeito - Questionário de Desenvolvimento de Estudantes de Psicologia. Os resultados apoiam a eficácia da intervenção e indicam mudanças ao nível do autoconhecimento, da representação de DP, do conhecimento do papel de Psicólogo, dos recursos para a transição entre papéis e contextos, da coerência e riqueza narrativa e das competências relacionais básicas. Não obstante as reformulações necessárias identificadas na avaliação informal, o programa promove o DP e a construção da identidade profissional dos estudantes de Psicologia, tendo os participantes demonstrado a sua satisfação com a mesma.

Professional Development (PD) has been highlighted as a critical element of professional training and practice within Psychology. Based on theory about PD and professional identity development and with an exploratory nature, we proceeded to the construction, implementation and evaluation of an intervention. Its main purpose is within a secure environment to exploration, to promote the PD of psychology students, in two components (intrapersonal and interpersonal/social). We formed two groups (one with 10 and another with five participants) that we evaluated formally by the pre-pos test design with a measure built for this purpose - Questionnaire Development Psychology Students. The results support the effectiveness of the intervention and indicate changes in: the level of self-knowledge, the representation of PD, the knowledge of the role of the psychologist, resources for the transition between roles and contexts, the consistency and richness of the narrative and basic relational skills. Despite the reformulations demanded by participants at the informal assessment, the program promotes the PD and the professional identity development of psychology students that presented high levels of satisfaction.
