Are you ready for retirement? The influence of values on membership in voluntary organizations in midlife and old age

Membership in voluntary organizations is associated with individual and social benefits. Due to the negative consequences of the global pandemic on older people, and the governmental challenges posed by population aging, voluntary membership is of great importance to society. To effectively promote volunteering among older people, it is necessary to understand the determinants of voluntary membership. This study analyses the influence of individual values—secular/traditional and survival/selfexpression– on voluntary membership among European adults (N = 31,985). Specifically, it examines which values orient two age groups (middle age: 50–64 and old age: 65–79), as well as men and women toward a certain type of association (Social Awareness; Professional and Political; Education and Leisure; Religion). The sample of 31,985 comprises 60% of adults aged 50–64 and 40% aged 65–79; of which 56% are women and 44% men. The empirical estimation considers different levels of data aggregation: individual, national and welfare system, therefore multilevel analysis is used as an analytical strategy. Individual-level variables from the Integrated Values Survey (2005/09, 2010/14, and 2017/20) and nationallevel variables (Gini Index and Gross Domestic Product Per Capita) from the World Bank and Eurostat are used. The results indicate that traditional and self-expression values promote membership in voluntary organizations in general more than secular and survival values. However, there are differences according to the type of organization. Furthermore, values are found to moderate the effect of age and gender on voluntary membership.Gobierno de Aragon CSO2017-82110-RSpanish Government PRE2018-083981State Research Agency BYCS S16_17

Crisis económica, salud e intervención psicosocial en España

La crisis económica que tuvo sus inicios en verano de 2008 ha impactado negativamente en los ámbitos psicológico, social y comunitario de las personas. Asimismo, las políticas basadas en la austeridad que se implementaron por parte de muchos gobiernos debilitaron los sistemas de protección social, lo que contribuyó a incrementar la vulnerabilidad de las personas que más sufrieron la crisis conduciendo, en muchos casos, a procesos o resultados de exclusión. En este trabajo hacemos, en primer lugar, una aproximación a las consecuencias negativas que la crisis ha producido en la salud mental de la población general y, especialmente, en dos de los grupos sociales más vulnerables como son la infancia/juventud y las personas migradas. También se analizan los efectos negativos de la crisis en la convivencia comunitaria, especialmente sobre las relaciones interculturales en una sociedad cada vez más multicultural. En segundo lugar, y dado que los datos de la investigación han puesto de relieve la importancia de factores psicosociales como moderadores de esos efectos negativos de la crisis económica sobre la salud y el bienestar psicológico, describimos algunas propuestas de intervención psicosocial que tienen en cuenta el apoyo a las familias, la mejora de las redes sociales, el empoderamiento de personas, grupos y comunidades, o la mejora de la competencia cultural de los servicios comunitarios.The economic crisis that began in the summer of 2008 has had a negative impact on the psychological, social and community spheres of people. In addition, the austerity policies implemented by many governments have weakened social protection systems, which have contributed to increase the vulnerability of the people who suffered most from the crisis, leading in many cases to processes of exclusion. In this paper, we evaluate the negative consequences that the crisis has had on the mental health of the general population, with a focus on two of the most vulnerable social groups such as children / youth and migrants. We further analyze the negative effects of the crisis on community life, in particular on intercultural relations in an increasingly multicultural society. Our data highlights the importance of psychosocial factors as moderators of the crisis’ negative effects on health and psychological well-being, which prompted us to describe some proposals for psychosocial intervention that take into account support for families, social network improvement, and empowerment of people, groups and communities, or cultural competency of community services

Genetically engineered mouse models of human B-cell precursor leukemias

This is an Open Access article distributed under the terms of the Creative Commons Attribution-Non-Commercial License.B-cell precursor acute lymphoblastic leukemias (pB-ALLs) are the most frequent type of malignancies of the childhood, and also affect an important proportion of adult patients. In spite of their apparent homogeneity, pB-ALL comprises a group of diseases very different both clinically and pathologically, and with very diverse outcomes as a consequence of their biology, and underlying molecular alterations. Their understanding (as a prerequisite for their cure) will require a sustained multidisciplinary effort from professionals coming from many different fields. Among all the available tools for pB-ALL research, the use of animal models stands, as of today, as the most powerful approach, not only for the understanding of the origin and evolution of the disease, but also for the development of new therapies. In this review we go over the most relevant (historically, technically or biologically) genetically engineered mouse models (GEMMs) of human pB-ALLs that have been generated over the last 20 years. Our final aim is to outline the most relevant guidelines that should be followed to generate an “ideal” animal model that could become a standard for the study of human pB-ALL leukemia, and which could be shared among research groups and drug development companies in order to unify criteria for studies like drug testing, analysis of the influence of environmental risk factors, or studying the role of both low-penetrance mutations and cancer susceptibility alterations.This work was supported by the German “Bundesamt fur Strah-lenschutz (BfS)” pilot project on childhood leukemia no. 3612S70029.

Efficient Implementation of Complementary Golay Sequences for PAR Reduction and Forward Error Correction in OFDM-based WLAN systems

In this paper the use of complementary Golay sequences (CGS) for peak-to-average power ratio (PAR) reduction and forward error correction (FEC) in an orthogonal frequency division multiplexing (OFDM)-based wireless local area network (WLAN) system is explored; performance is examined and complexity issues are analyzed. We study their PAR reduction performance depending on sequence lengths and we have found that, for the case that the number of sub-carriers differs from the sequence length, some interesting relationships can still be stated. Regarding their error correction capabilities, these sequences are investigated considering M-PSK constellations applied to the OFDM signal specified in IEEE 802.11a standard. Computational load for both Golay encoding and decoding processes is addressed and we provide an exhaustive analysis of their complexity. In order to overcome memory restrictions and speed up algorithmic operations, a novel algorithm for real-time generation of the Golay Base Sequences is proposed and evaluated giving as a conclusion that these sequences can be real-time generated with actual Digital Signal Processors (DSP). Our proposal lies on an efficient permutation algorithm that obtains the current permutation without the need for generating previous ones. Its complexity is calculated and turns out to be significantly low; the advantages are specially appreciated at the decoding stage. We also introduce a hybrid solution to get a trade-off between complexity and memory requirements. Moreover, the whole system is also implemented in a DSP to validate the proposal in a prototype, where its feasibility has been confirmed.This work has been partly funded by the Spanish government with projects MACAWI (TEC 2005-07477-c02-02) and MAMBO (UC3M-TEC-05-027)

Socio-emotional wealth and corporate responses to environmental hostility:Are family firms more stakeholder oriented?

Do family firms care more for different stakeholders than nonfamily firms when operating in a hostile business environment? This study addresses this question and fills the existing void in family business research. It shows that family-controlled firms adopt corporate social responsibility strategies and balance the demands of internal and external interest groups to preserve their socio-emotional wealth while facing fierce competition, resource scarcity, and penurious economic conditions. More specifically, our analysis of an international sample of 956 listed firms from 2006 to 2014 reveals that family firms show a higher level of corporate social responsibility (CSR) performance and better stakeholder orientation than nonfamily firms. Our findings are useful for managers, policymakers, and responsible investors

Differentiation of Trichuris species using a morphometric approach

Trichuris trichiura is a nematode considered as the whipworm present in humans and primates. The systematics of the genus Trichuris is complex. Morphological studies of Trichuris isolated from primates and humans conclude that the species infecting these hosts is the same. Furthermore, numerous molecular studies have been carried out so far to discriminate parasite species from humans and Non-Human Primates using molecular techniques, but these studies were not performed in combination with a parallel morphological study. The hypothesised existence of more species of Trichuris in primates opens the possibility to revise the zoonotic potential and host specificity of T. trichiura and other putative new species of whipworms. In the present work, a study of Trichuris Roederer, 1761 (Nematoda:Trichuridae) parasitizing C. g. kikuyensis, P. ursinus, Macaca sylvanus, Pan troglodytes, and Sus scrofa domestica has been carried out using modern morphometric techniques in order to differentiate populations of Trichuris isolated from four species of captive NHP from different geographical regions, and swine, respectively. The results obtained revealed strong support for geometrical morphometrics as a useful tool to differentiate male Trichuris populations. Therefore, morphometrics in combination with other techniques, such as molecular biology analyses, ought to be applied to further the differentiation of male populations. On the other hand, morphometrics applied to female Trichuris species does not seem to contribute new information as all the measurements combinations of obtained from females always showed similar resultsMinistry of Economy,Industry and Competitiveness(CGL2017-83057)FEDER funds, the Junta de Andalucía (BIO-338)V Plan Propio de Investigación of the University of Sevill
