Ajuste al retiro laboral en función del tipo de retiro y su voluntariedad desde una perspectiva de género [Retirement fit as a function of the retirement type and voluntariness: a gender view]
En el presente trabajo examinamos el ajuste al retiro laboral, examinando la satisfacción con la jubilación y bienestar psicológico en una muestra de 260 prejubilados y jubilados. Se consideraron tres factores: el tipo de retiro (prejubilación o jubilación), la percepción de la medida en que la salida del rol laboral fue voluntaria (voluntariedad) y el género. Los resultados muestran que las personas que se jubilaron y que lo hicieron voluntariamente perciben mayores niveles de satisfacción con la jubilación y bienestar psicológico en comparación con los que se prejubilaron y aquellos que lo hicieron obligatoriamente, respectivamente. Además se puso de manifiesto la interacción entre las variables consideradas en sus efectos sobre la satisfacción y el bienestar. En esta línea, entre los obligatoriamente prejubilados, las mujeres experimentan menor nivel de satisfacción con la jubilación que los hombres. Sin embargo, entre los obligatoriamente jubilados, son los hombres los que experimentan menor nivel de satisfacción con la jubilación. En relación a dichos resultados, el presente trabajo subraya la importancia de estudiar e intervenir sobre la mejora del ajuste en la experiencia del retiro laboral atendiendo tanto a las características de género como a las del proceso de transición (jubilación-prejubilación, voluntariedad-obligatoriedad). ABSTRACT: The present study analyses the adjustment to retirement in terms of satisfaction and psychological well-being in a sample of 270 early and on-time retirees. Three factors were taken into consideration -type of retirement (early vs on-time retirement), perception of the extent to which retirement was retiro laboral, (voluntariness) and gender. The results show that participants who retired on-time and whose decision was taken voluntarily perceive higher levels of satisfaction with retirement and psychological well-being when compared to early retirees and to those who perceive retirement as obligatory respectively. Results also show an interaction between the three factors in the impact of retirement on satisfaction and wellbeing. Among obligatory early retired, women experience lower levels of satisfaction with retirement compared to men. However, among the obligatory on-time retirees, men perceive lower levels of satisfaction with retirement than women. Based on these findings, this study emphasizes the importance of examining and intervening in retirement fit, taking into consideration the characteristics of both gender and transition process -i.e., early vs on-time retirement and voluntary vs obligatory retirement
Innovation and creativity in organizations: a state-of-the-science review, prospective commentary, and guiding framework
YesCreativity and innovation in any organization are vital to its successful performance. The authors review the rapidly growing body of research in this area with particular attention to the period 2002 to 2013, inclusive. Conceiving of both creativity and innovation as being integral parts of essentially the same process, we propose a new, integrative definition. We note that research into creativity has typically examined the stage of idea generation, whereas innovation studies have commonly also included the latter phase of idea implementation. The authors discuss several seminal theories of creativity and innovation and then apply a comprehensive levels-of-analysis framework to review extant research into individual, team, organizational, and multilevel innovation. Key measurement characteristics of the reviewed studies are then noted. In conclusion, we propose a guiding framework for future research comprising 11 major themes and 60 specific questions for future studies.Grant IN-2012-095 from the U.K. Leverhulme Trust awarded to the first author and by British Academy Grant SG110409 awarded to the second author
Two-electronic component behavior in the multiband FeSeTe superconductor
We report X-band EPR and Te and Se NMR measurements on
single-crystalline superconducting FeSeTe ( = 11.5(1)
K). The data provide evidence for the coexistence of intrinsic localized and
itinerant electronic states. In the normal state, localized moments couple to
itinerant electrons in the Fe(Se,Te) layers and affect the local spin
susceptibility and spin fluctuations. Below , spin fluctuations become
rapidly suppressed and an unconventional superconducting state emerges in which
is reduced at a much faster rate than expected for conventional - or
-wave symmetry. We suggest that the localized states arise from the
strong electronic correlations within one of the Fe-derived bands. The
multiband electronic structure together with the electronic correlations thus
determine the normal and superconducting states of the FeSeTe
family, which appears much closer to other high- superconductors than
previously anticipated.Comment: 5 pages, 4 figure
Integrating organizational research–Individual, team, organizational and multilevel perspectives
Organizations are multilevel social systems (Hedberg, Nystrom, & Starbuck, 1976; Kesler & Kates, 2015) where (1) diverse employees are assigned to various jobs, embedded in multiple dyadic relationships, and expected to play diverse team roles; (2) functional and/or cross-functional teams integrate individual efforts and develop intra- and inter-group dynamics; and (3) multiple departments and business processes nested within or spanning across organizational boundaries deliver value through mutual interaction. Whereas the managerial priority in the globally digitalized world is to execute competitive strategic initiatives and achieve challenging business goals by vigilantly managing and continuously improving dynamic interactions between organizational system levels, the majority of scholars still populate disciplinary, specialized micro- (social psychology, organizational behavior, and organizational psychology), meso- (business process management and project management) or macro- (strategic management, organizational theory and design, and engineering/systems management) research camps (e.g., Hitt, Beamish, Jackson, & Mathieu, 2007; Molloy, Ployhart, & Wright, 2011)..
Milking Characteristics of Istrian and Littoral Dinaric Donkey Breeds
Istrian and Littoral Dinaric donkey are autochthonous breeds which habitat primarily in the Mediterranean part of Croatia. During the second half of the 20th century they have lost primary function as working animals, which led to breeds suppression. Nowadays these two breeds are in the status of endangered ones. One of the possibilities for their economic re-affirmation is launching the program for production and processing donkey’s milk. The aim of the study was to determine the possibility of milk production of Istrian and Littoral Dinaric jennies in terms of quantity and chemical composition. Istrian jennies produce 745.4 mL/milking while Littoral Dinaric produce 317.8 mL/milking. Milk form Littoral Dinaric jennies contained a significantly higher proportion of milk fat and proteins. There were no significant differences in the content of lactose, dry matter, number of somatic cells and microorganisms in milk between these two breeds. Considering the potential for milk production and milk quality, we believe that both breeds are suitable for integration in the programs for milk production, thus enabling for both population to be economically sustainable. It is necessary to develop production technology and markets, with special emphasis considering quality of donkey milk and safety of consumers
Antiferromagnetic fluctuations in the normal state of LiFeAs
We present a detailed study of 75As NMR Knight shift and spin-lattice
relaxation rate in the normal state of stoichiometric polycrystalline LiFeAs.
Our analysis of the Korringa relation suggests that LiFeAs exhibits strong
antiferromagnetic fluctuations, if transferred hyperfine coupling is a dominant
interaction between 75As nuclei and Fe electronic spins, whereas for an on-site
hyperfine coupling scenario, these are weaker, but still present to account for
our experimental observations. Density-functional calculations of electric
field gradient correctly reproduce the experimental values for both 75As and
7Li sites.Comment: 5 pages, 3 figures, thoroughly revised version with refined

Multi-locus genetic risk score predicts risk for Crohn's disease in Slovenian population
AIM: To develop a risk model for Crohn's disease (CD) based on homogeneous population.METHODS: In our study were included 160 CD patients and 209 healthy individuals from Slovenia. The association study was performed for 112 single nucleotide polymorphisms (SNPs). We generated genetic risk scores (GRS) based on the number of risk alleles using weighted additive model. Discriminatory accuracy was measured by area under ROC curve (AUC). For risk evaluation, we divided individuals according to positive and negative likelihood ratios (LR) of a test, with LR > 5 for high risk group and LR <0.20 for low risk group.RESULTS: The highest accuracy, AUC of 0.78 was achieved with GRS combining 33 SNPs with optimal sensitivity and specificity of 75.0% and 72.7%, respectively. Individuals with the highest risk (GRS > 5.54) showed significantly increased odds of developing CD (OR = 26.65, 95% CI: 11.25-63.15) compared to the individuals with the lowest risk (GRS <4.57) which is a considerably greater risk captured than in one SNP with the highest effect size (OR = 3.24). When more than 33 SNPs were included in GRS, discriminatory ability was not improved significantly; AUC of all 74 SNPs was 0.76.CONCLUSION: The authors proved the possibility of building accurate genetic risk score based on 33 risk variants on Slovenian CD patients which may serve as a screening tool in the targeted population.</p
National single-step genomic method that integrates multi-national genomic information
The aim of this paper was to develop a national single-step genomic BLUP that integrates multi-national genomic estimated breeding values (EBV) and associated reliabilities without double counting dependent data contributions from the different evaluations. Simultaneous use of all data, including phenotypes, pedigree, and genotypes, is a condition to obtain unbiased EBV. However, this condition is not always fully met, mainly due to unavailability of foreign raw data for imported animals. In dairy cattle genetic evaluations, this issue is traditionally tackled through the multiple across-country evaluation (MACE) of sires, performed by Interbull Centre (Uppsala, Sweden). Multiple across-country evaluation regresses all the available national information onto a joint pedigree to obtain country-specific rankings of all sires without sharing the raw data. In the context of genomic selection, the issue is handled by exchanging sire genotypes and by using MACE information (i.e., MACE EBV and reliabilities), as a valuable source of “phenotypic” data. Although all the available data are considered, these “multi-national” genomic evaluations use multi-step methods assuming independence of various sources of information, which is not met in all situations. We developed a method that handles this by single-step genomic evaluation that jointly (1) uses national phenotypic, genomic, and pedigree data; (2) uses multi-national genomic information; and (3) avoids double counting dependent data contributions from an animal’s own records and relatives’ records. The method was demonstrated by integrating multi-national genomic EBV and reliabilities of Brown Swiss sires, included in the InterGenomics consortium at Interbull Centre, into the national evaluation in Slovenia. The results showed that the method could (1) increase reliability of a national (genomic) evaluation; (2) provide consistent ranking of all animals: bulls, cows, and young animals; and (3) increase the size of a genomic training population. These features provide more efficient and transparent selection throughout a breeding program
Alzheimer\u27s disease and vascular dementia in developing countries: prevalence, management, and risk factors
Despite mortality due to communicable diseases, poverty, and human conflicts, dementia incidence is destined to increase in the developing world in tandem with the ageing population. Current data from developing countries suggest that age-adjusted dementia prevalence estimates in 65 year olds are high (≥5%) in certain Asian and Latin American countries, but consistently low (1–3%) in India and sub-Saharan Africa; Alzheimer\u27s disease accounts for 60% whereas vascular dementia accounts for ∼30% of the prevalence. Early-onset familial forms of dementia with single-gene defects occur in Latin America, Asia, and Africa. Illiteracy remains a risk factor for dementia. The APOE ε4 allele does not influence dementia progression in sub-Saharan Africans. Vascular factors, such as hypertension and type 2 diabetes, are likely to increase the burden of dementia. Use of traditional diets and medicinal plant extracts might aid prevention and treatment. Dementia costs in developing countries are estimated to be US$73 billion yearly, but care demands social protection, which seems scarce in these regions
ES-Cell Derived Hematopoietic Cells Induce Transplantation Tolerance
Background: Bone marrow cells induce stable mixed chimerism under appropriate conditioning of the host, mediating the induction of transplantation tolerance. However, their strong immunogenicity precludes routine use in clinical transplantation due to the need for harsh preconditioning and the requirement for toxic immunosuppression to prevent rejection and graft-versus-host disease. Alternatively, embryonic stem (ES) cells have emerged as a potential source of less immunogenic hematopoietic progenitor cells (HPCs). Up till now, however, it has been difficult to generate stable hematopoietic cells from ES cells. Methodology/Principal Findings: Here, we derived CD45 + HPCs from HOXB4-transduced ES cells and showed that they poorly express MHC antigens. This property allowed their long-term engraftment in sublethally irradiated recipients across MHC barriers without the need for immunosuppressive agents. Although donor cells declined in peripheral blood over 2 months, low level chimerism was maintained in the bone marrow of these mice over 100 days. More importantly, chimeric animals were protected from rejection of donor-type cardiac allografts. Conclusions: Our data show, for the first time, the efficacy of ES-derived CD45 + HPCs to engraft in allogenic recipient
