OBJECTIVES: The present study examined the impact of cumulative trauma exposure on current posttraumatic stress disorder (PTSD) symptom severity in a nonclinical sample of adults in their 60s. The predictive utility of cumulative trauma exposure was compared to other known predictors of PTSD, including trauma severity, personality traits, social support, and event centrality. METHOD: Community-dwelling adults (n = 2515) from the crest of the Baby Boom generation completed the Traumatic Life Events Questionnaire, the PTSD Checklist, the NEO Personality Inventory, the Centrality of Event Scale, and rated their current social support. RESULTS: Cumulative trauma exposure predicted greater PTSD symptom severity in hierarchical regression analyses consistent with a dose-response model. Neuroticism and event centrality also emerged as robust predictors of PTSD symptom severity. In contrast, the severity of individuals' single most distressing life event, as measured by self-report ratings of the A1 PTSD diagnostic criterion, did not add explanatory variance to the model. Analyses concerning event categories revealed that cumulative exposure to childhood violence and adulthood physical assaults were most strongly associated with PTSD symptom severity in older adulthood. Moreover, cumulative self-oriented events accounted for a larger percentage of variance in symptom severity compared to events directed at others. CONCLUSION: Our findings suggest that the cumulative impact of exposure to traumatic events throughout the life course contributes significantly to posttraumatic stress in older adulthood above and beyond other known predictors of PTSD.

Avec la vague des départs à la retraite amorcée par la génération des baby-boomers, le marché du travail canadien traversera inéluctablement une période de transition. Le vide laissé par ces départs obligera de nombreuses industries à réajuster leur tir afin de ne pas être secouées par de trop fortes turbulences. À cet effet, l’impact des retraites n’aura pas la même ampleur pour chacune des branches d’activité. S’appuyant sur les données longitudinales de l’Enquête sur la dynamique du travail et du revenu de 1993 à 2010, cette recherche analyse les tendances au fil du temps et entre les industries en regard des départs d’emploi de carrière. Une attention particulière est aussi portée aux emplois de transition selon le secteur d’activité, afin de déterminer si cette pratique peut amoindrir les répercussions des départs d’emploi de carrière. Les résultats montrent que l’intensité des départs d’emploi de carrière s’accroit au cours de la période considérée et que d’importantes variations existent entre les travailleurs des diverses catégories d’industries examinées. L’industrie des services professionnels, scientifiques et techniques affiche la plus faible proportion de travailleurs ayant quitté un emploi de carrière (26 %). À l’autre extrémité du spectre, les travailleurs du secteur de l’hébergement et des services de restauration présentent la plus forte probabilité d’effectuer un départ d’emploi de carrière (47 %). Au chapitre des emplois de transition, les travailleurs en provenance l’industrie de la construction montrent la plus forte propension à oeuvrer au sein d’un tel type d’emploi. Si certaines industries se démarquent des autres, cela s’explique surtout en raison du comportement différentiel des travailleurs les plus âgés (55 à 64 ans).

Development of an efficient tissue culture protocol in coconut is hampered by numerous technical constraints. Thus a greater understanding of the fundamental aspects of embryogenesis is essential. The role of AINTEGUMENTA-like genes in embryogenesis has been elucidated not only in model plants but also in economically important crops. A coconut gene, CnANT, that encodes two APETALA2 (AP2) domains and a conserved linker region similar to those of the BABY BOOM transcription factor was cloned, characterized, and its tissue specific expression was examined. The full-length cDNA of 1,780 bp contains a 1,425-bp open reading frame that encodes a putative peptide of 474 amino acids. The genomic DNA sequence includes 2,317 bp and consists of nine exons interrupted by eight introns. The exon/intron organization of CnANT is similar to that of homologous genes in other plant species. Analysis of differential tissue expression by real-time polymerase chain reaction indicated that CnANT is expressed more highly in in vitro grown tissues than in other vegetative tissues. Sequence comparison of the genomic sequence of CnANT in different coconut varieties revealed one single nucleotide polymorphism and one indel in the first exon and first intron, respectively, which differentiate the Tall group of trees from Dwarfs. The indel sequence, which can be considered a simple sequence repeats marker, was successfully used to distinguish the Tall and Dwarf groups as well as to develop a marker system, which may be of value in the identification of parental varieties that are used in coconut breeding programs in Sri Lanka.

Knowledge of the molecular biological changes underlying the process of embryogenesis is important for the improvement of somatic embryogenesis of coconut. Among the transcription factors that control the transition from vegetative to embryogenic growth, members of APETALA2/Ethylene-responsive element binding protein domain family play an important role in promoting embryo development. Significant insights into the role of AP2 genes have been obtained by the ectopic expression of AP2 sub family genes in transgenic Arabidopsis. A homolog of the AINTEGUMENTA-like gene that encodes the two AP2 domains and the linker region was identified in the coconut genome. Phylogenetic analysis showed that this gene, CnANT, encodes a protein that branched with BABY BOOM/PLETHORA clade in the AINTEGUMENTA-like major clade and was similar to the oil palm EgAP2-1 protein. According to real time RT-PCR results, higher expression of CnANT was observed in more mature zygotic embryos. Also, high CnANT expression was recorded in embryogenic callus compared to other stages of somatic embryogenesis. We examined the effect of ectopic CnANT expression on the development and regenerative capacity of transgenic Arabidopsis. Overexpression of CnANT in Arabidopsis induced hormone free regeneration of explants. Furthermore, ectopic expression of CnANT enhanced regeneration in vitro and suggested a role for this gene in cell proliferation during in vitro culture.

En este artículo abordamos el significado de la familia adoptiva a partir del análisis del discurso de los relatos autobiográficos de madres y padres adoptivos españoles. En un contexto de vacío de cultura adoptiva, las familias adoptivas publican narraciones para ser valoradas como «normales» al tiempo que, en ausencia de modelos de referencia, definen su modelo de familia desdibujando el arquetipo familiar instituido. A partir del método biográfico, aplicamos un doble ejercicio sociológico de (1) deconstrucción ideológica del modelo de familia hegemónico a partir de la (2) construcción del significado que padres y madres adoptivas otorgan a su familia. Las teorías de la familia postmoderna y las teorías feministas postestructuralistas enmarcan el análisis crítico del discurso con perspectiva de género con el que es abordado el estudio de estos singulares documentos personales.

El artículo tiene como objetivo el análisis del proceso de construcción social del fenómeno de las adopciones en España, que tendrá mayor relevancia numérica e impacto social en la década de los noventa con el incremento de las adopciones internacionales. Las conclusiones que se presentan surgen de la investigación documental llevada a cabo en documentos oficiales y personales. Las leyes, normas y decretos que se revisan son examinados en su estructura social y al hilo de las ideologías dominantes sobre maternidad, crianza, infancia y familia. Se incluye el legado normativo que el movimiento por la recuperación de la memoria histórica ha dotado de contemporaneidad, al tiempo que nos sitúa en la construcción actual de la adopción. Esta visión diacrónica se completa con el análisis de documentos personales autobiográficos. Si significativo es el incremento de las adopciones internacionales en España, también lo es el importante número de documentos personales en los que madres y padres relatan en primera persona su experiencia con la adopción. Sus narraciones son críticas con la gestión del proceso de la adopción y con la ideología que subyace, basada en la construcción de la diferencia con fuerte sesgo a favor del modelo biológico y en la sacralización del niño adoptado. En sus relatos se sigue el proceso contemporáneo de construcción identitario, individual y social de la adopción en España.

Against the background of looming demographic decline, the departure of the baby-boom generation from European labour markets and growing economic competitiveness from emerging economies, this CEPS Policy Brief, published jointly with the Bertelsmann Stiftung, looks into the potential benefits of increased intra-EU labour mobility. The authors examine the ‘German case’ on EU labour mobility, digging below the surface of the aggregate data. They offer proposals on how to foster a European fair deal on talent, one that would benefit the EU as a whole. The paper concludes with policy recommendations on how to increase the potential benefits of the freedom of movement for both individual EU citizens and for the EU as a whole.

This master thesis aims to identify work-related factors making Belgian nurses consider leaving their job voluntary and to compare the work-related factors across different generations. The purpose of this master thesis has a descriptive nature of research. The research approach chosen is a deductive approach and the research design chosen is a quantitative research design. Cluster sampling in combination with simple random sampling was used as sampling technique. 128 nurses were surveyed from April to May 2016. Nurses who reported to leave the organization due to retirement reasons, temporary employment contract or maternity leave were excluded from the study as this study investigates the voluntary turnover intention. A total of 68 nurses were included in the study which indicates an overall response rate of 53 %. Numerous of the findings in this master thesis are consistent with previous studies on turnover intention of different generations in other western-countries than Belgium. The work-related factor workload was most often reported by Belgian nurses with no intention to leave their job. Belgian nurses with an intention to leave their job indicated most often the work-related factor (non-)financial benefits. The generation-specific findings indicated both similarities and differences between the work-related factors selected. It was observed that Baby Boomers with an intention to leave their job selected most often variables related to the work-related factors (non-)financial benefits, supportive organization and workload. The variable lack of recognition appeared among Baby Boomers with an intention and no intention to leave their job. Surprisingly was the often selected variables lack of direct and/clear feedback on performances and unsupportive supervisor among Baby Boomers with professional turnover intention. Further, it was observed that Generation Xers with an intention to leave their job selected most often variables related to the work-related factors supportive organization, communication, (non-)financial benefits, work content and workload. The variables inadequate opportunity for advancement/professional growth and imbalance work-life appeared among Generation Xers with an intention and no intention to leave their job. Generation Yers with an intention to leave their job selected most frequently variables related to the work-related factors (non-)financial benefits, workload and commitment. The variables inadequate salary and opportunities elsewhere appeared among nurses with an intention and no intention to leave their job. Surprisingly was the often selected variable inadequate salary among Generation Yers with professional turnover intention.

Las sociedades en el mundo desarrollado se enfrentan con uno de los retos más importantes que se les han presentado en los últimos años: el envejecimiento de su población. Las empresas se encuentran con un grupo relevante de empleados de la mayor generación que haya existido nunca, la que se dio en llamar “generación del baby boom”, están próximos a la jubilación. Si bien la literatura nos muestra que, si bien, no va a haber escasez de recursos humanos en general, sí se producirá en puestos en los que se requiera mayor cualificación y experiencia. Faltarán, por tanto, recursos cualificados en todos los países desarrollados. En estas circunstancias, las empresas tienen la necesidad de gestionar sus plantillas de modo que la edad o la proximidad a la jubilación de sus trabajadores sea un parámetro significativo. Es necesario que se identifiquen los individuos que atesoran conocimientos y habilidades que se consideren clave, se debe conocer en qué banda de edad están las personas que atesoran ese conocimiento clave y se tendrían que conocer cuáles son sus intenciones frente a la jubilación más o menos cercana, con el objeto de planificar su abandono de la empresa o, por el contrario, intentar disuadirles de sus intenciones. Las decisiones sobre la jubilación requieren de largos períodos de maduración. Por ello es necesario crear un marco que permita predecir las decisiones respecto a la jubilación y gestionar correctamente los recursos con la suficiente antelación. Para que todo ello sea posible es necesario el establecimiento de una regulación laboral que facilite la prolongación de la vida laboral de estos empleados...
