Objectives: The aim of this project was to validate, in a Portuguese population, two forensic methods of dental age estimation – Schour and Massler charts and the London atlas. Materials and Methods: The test sample was composed by 108 dental radiographs of living and known-age individuals. Dental age was estimated according to each method. Chronological age was then compared to the estimated dental age using individual t-test and paired t-test. Results: Results showed that the Schour and Massler charts underestimated age and the London atlas overestimated age. Nevertheless, the London atlas performed better in all measures. Mean differences for both the London atlas and Schour and Massler were 0,1389 and -5,4167 months respectively. Schour and Massler charts showed significant statistical difference between dental age and chronological age (p <0.05). Discussion and Conclusions: We conclude that, in the evaluated sample, age estimation using the London atlas represents an improvement in forensic age estimation from developing teeth. Further studies should be done with a larger Portuguese population sample.

Material orgânico de superfície em solos florestais sob diferentes paisagens da Mata Atlântica.

O bioma Mata Atlântica é considerado um ?hotspot? por conter uma alta diversidade de espécies e um alto grau de endemismo. Além de abrigar grande parte da população brasileira, este bioma encontra-se altamente fragmentado e é considerado um bioma estratégico para a conservação. Nesse sentido, a utilização de ferramentas simples para a avaliação dos processos geobioquímicos, como a serapilheira (Formas de Humus) parecem interessantes. Portanto, o trabalho tem como alvo avaliar e quantificar as Formas de Humus em gradiente altitudinal. Para esse fim, foram escolhidos 3 municípios da paisagem da Mata Atlântica em diferentes altitudes, e avaliados o material orgânico de superfície de dois sistemas (Natural e Plantios de Eucalipto) em cada município. Os resultados mostram uma clara diferença entre os estoques da serapilheira com a altitude, sendo entre os sistemas naturais, os do município de Friburgo com os maiores estoques. Mudanças nos estoques de serapilheira, como quantidade de galhos, dos plantios de Eucalipto parecem responder positivamente a estrutura e a idade dos sistemas. Os resultados também mostram associações positivas entre quantidade de material fresco e quantidade de raízes finas. Por fim, o estudo com serapilheira, a luz das Formas de Humus, pode ajudar a diagnosticar e classificar sistemas

Employees’ fit to telework and work well-being: (in)voluntariness in telework as a mediating variable?

Purpose: The present study aims to examine the mediating role of (in)voluntariness in teleworking in explaining the relationship between employees’ fit to telework and work well-being (i.e. work engagement and exhaustion). Design/methodology/approach: A cross-sectional survey design was used in this study. The sample comprised 222 individuals performing telework in Portugal. Statistical analyses employed were descriptive statistics, Pearson’s correlation, confirmatory factor and structural equation analyses, and mediation analysis using Hayes Process macro. Findings: The findings confirmed the hypothesis that employees’ fit to telework raises the voluntariness in telework and decreases involuntariness in telework. However, contrary to expectations, no significant relationships were found between voluntariness in telework, work engagement and exhaustion. Yet, involuntariness in telework showed a significant role in decreasing work engagement and increasing workers’ exhaustion. The mediating role of involuntariness in telework was confirmed in explaining the relationship between employees’ fit to telework and exhaustion. Practical implications: Managers in global firms can draw from the results to understand how employees’ fit to telework directly and/or indirectly contributes to work well-being and develop human resource (HR) management practices aiming to increase employees’ fit to telework. Originality/value: Although teleworking is already studied, to the best of the authors’ knowledge, no studies have analyzed the same conceptual model employees’ fit to telework, (in)voluntariness in teleworking and work well-being.info:eu-repo/semantics/acceptedVersio

Through the lens of workers’ motivation: does it relate to work–family relationship perceptions?

Workers’ motivations and the work–family relationship are two subjects that have been capturing the attention of researchers and practitioners. However, to date, little is known about the link between the two subjects. Thus, this research aimed to investigate the relationships among each type of motivation conceptualized in self-determination theory and work–family conflict, work–family enrichment, and work–family balance. In addition, the current study intended to investigate the relationships among work–family conflict, work–family enrichment, and Work–family balance. Data were collected through a self-administered questionnaire. To test the hypotheses, the PROCESS macro was used. The results suggested that intrinsic motivation is negatively associated with work–family conflict and positively associated with work–family enrichment and work–family balance. Additionally, identified regulations seem to be positively associated with work–family enrichment and work–family balance. However, contrary to expectations, this study revealed a positive relationship between introjected regulation and work–family enrichment and work–family balance. Concerning external regulation (material and social) and amotivation, globally, the findings were consistent with the hypotheses, i.e., the higher the external regulation and amotivation, the higher work–family conflict and the lower the work–family enrichment and work–family balance. Moreover, the higher the work–family conflict, the lower the work–family balance, and the higher the work–family enrichment, the higher the work–family balance. Theoretical and practical implications are discussed.info:eu-repo/semantics/publishedVersio

Does oral polio vaccine have non-specific effects on all-cause mortality? Natural experiments within a randomised controlled trial of early measles vaccine.

BACKGROUND: BCG and measles vaccine (MV) may have beneficial non-specific effects (NSEs). If an unplanned intervention with a vaccine (a natural experiment) modifies the estimated effect in a randomised controlled trial (RCT), this suggests NSEs. We used this approach to test NSEs of triple oral polio vaccine (OPV). METHODS: During an RCT of 2 doses of MV at 4.5 and 9 months versus 1 dose of MV at 9 months of age, we experienced 2 natural experiments with OPV. We assessed whether these OPV experiments modified the effect of 2-dose MV in the MV trial. SETTING: MV RCT conducted in urban Guinea-Bissau 2003-2009. INTERVENTIONS: Natural experiments with OPV due to missing vaccine and the implementation of OPV campaigns. MAIN OUTCOME MEASURE: Changes in the mortality rate ratio (MRR) for 2-dose MV versus 1-dose MV. RESULTS: First, the MRR (2-dose/1-dose MV) overall was 0.70 (0.52 to 0.94), but the MRR was 1.04 (0.53 to 2.04) when OPV at birth (OPV0) was not given, suggesting that early priming with OPV was important for the effect of 2-dose MV. The effect of OPV0 depended on age of administration; the MRR (2-dose/1-dose MV) was 0.45 (0.29 to 0.71) for children receiving OPV0 in the first week of life, but 3.63 (0.87 to 15.2) for those receiving OPV0 after the first month of life (p=0.007, test of no interaction). Second, campaign-OPV may have reduced the difference between the randomisation groups since the MRR (2-dose/1-dose MV) was 0.60 (0.42 to 0.85) for children who had not received campaign-OPV before RCT-enrolment versus 0.72 (0.23 to 2.31) and 1.42 (0.70 to 2.90) for children who had received 1 or 2 doses of campaign-OPV-before-enrolment, respectively. CONCLUSIONS: Bissau had no polio infection during this trial, so OPV0 and campaign-OPV may have NSEs since they modified the effect of 2-dose MV in an RCT. Different interventions may interact to a much larger effect than usually assumed
