Jobs as Lancaster Goods: Facets of Job Satisfaction and Overall Job Satisfaction

Overall job satisfaction is likely to reflect the combination of partial satisfactions related to various features of one’s job, such as pay, security, the work itself, working conditions, working hours, and the like. The level of overall job satisfaction emerges as the weighted outcome of the individual’s job satisfaction with each of these facets. The purpose of this study is to determine the extent and importance of partial satisfactions in affecting and explaining overall job satisfaction. Using the European Community Household Panel (ECHP) a two layer model is estimated which proposes that job satisfaction with different facets of jobs are interrelated and the individual’s reported overall job satisfaction depends on the weight that the individual allocates to each of these facets. For each of the ten countries examined, satisfaction with the intrinsic aspects of the job is the main criterion which workers use to evaluate their job and this is true for both the short and the long term.European Commissio

Identifying causal paths between health and socio-economic status: Evidence from European older workforce surveys

relationship. In addition, such a relationship takes place early in life and keeps on evolving over time so that both one’s health and SES at a given point in time result from the cumulative effects of this spiral. Thus, only by simultaneously accounting for both pathways as well as for their dynamics would one be able to provide a clear picture of both the process of health accumulation and the dynamics of SES formation. We estimate a structural model where a variety of causal paths between different health dimensions and SES measures as well as their dynamics are simultaneously accounted for. This allows distinction between significant causal paths and insignificant ones, while accounting for endogeneity as well as for cofounders. We use the SOCIOLD survey where the targeted population is that of the older workforce (50 and older) from six EU countries (Denmark, Finland, France, Greece, the Netherlands and the UK). Our results show that (i) reverse causality is indeed a crucial issue: one’s previous socio-economic status influences current health and previous health influences current socioeconomic status, (ii) there are cumulative effects in the sense that both health and socio-economic statuses depend on their past values and (iii) the results are sensitive to whether simultaneity is explicitly accounted for or not.Health status; Socio-economic status; Causal paths; Asymptotic least squares

Children's first names and immigration background in France

We present evidence indicating that immigrants and especially those from the Maghreb/Middle-East give first names to their children that are different from those given by the French majority population. When it comes to natives with an immigrant background, these differences are very little pronounced. Being born and raised up in France as well as being exposed to the French society and culture through residence, citizenship and the educational system draws individuals with or without immigrant background into similar ways of expressing belongings when choosing first names for their children, indicating the very strong assimilating forces in the French society.First names; integration; belonging; immigrants.

Diets containing shrimp protein hydrolysates provided protection to European sea bass (Dicentrarchus labrax) affected by a Vibrio pelagius natural infection outbreak

This study was conducted to investigate the effects of the dietary supplementation of shrimp protein hydrolysate (SPH) on somatic growth performance, innate immune response in juvenile European sea bass (Dicentrarchus labrax) and their differential cumulative mortality when affected by a Vibrio pelagius natural infection outbreak. A diet containing 20% fish meal (FM) was used as a control, whereas three other diets differing in the level of FM inclusion (75 and 25% FM replacement by plant protein sources) and the inclusion of the additive (5% FM, 5% FM + 5% SPH and 15% FM + 5% SPH) were tested. After 110 days, there were no statistically significant differences in somatic growth parameters nor proximate composition in fish fed different experimental diets (P > 0.05), while the humoral non-specific immune responses (lysozyme, bacteriolytic and complement activities) were significantly enhanced by the inclusion of SPH in diets (P < 0.05). Additionally, an outbreak of the pathogenic bacteria V. pelagius, a bacterial species previously described as producer of the virulence factor hemolysin, occurred in all experimental tanks (4 replicates per diet) due to crowding and repeated handling stress for fish sorting. Survival rates among different experimental groups ten days after the bacterial epizootic differed depending on the diets, with groups containing SPH showing the best results (P < 0.05). In particular, fish fed the 15% FM + 5% SPH diet showed the highest survival rate (96.4 ± 5.0%), followed by those fed the 5% FM5 + 5% SPH5 (61.8 ± 16.3%). In contrast, survival rates in fish fed diets deprived of the additive (20% FM and 5% FM5 diets) were the lowest ones (32.0 ± 6.7% and 38.2 ± 13.5%, respectively). The present study showed that SPH can be incorporated in aquafeeds with high levels of FM substitution by PP sources without detrimental impact on the somatic growth performance of fish. In addition, the non-specific humoral immunity in seabass and their survival when affected by an epizootic outbreak of V. pelagius were positively affected, which showed the immunomodulatory benefits of shrimp protein hydrolysate to promote health and prevent diseases in fish.info:eu-repo/semantics/acceptedVersio
