Changes in the Satisfaction of Cohabitors Relative to Spouses Over Time

Family scholars have noted a gap in the subjective well‐being of cohabitors relative to spouses and have hypothesized that the size of this “cohabitation gap” varies depending on how far cohabitation has diffused in a society. For the first time we test this hypothesis across time in a single country, Italy, by analyzing 20 cross‐sectional, nationally representative surveys collected from 1993 to 2013 by the Italian Institute of Statistics (N = 279,190 partnered young adults). We find that differences in the assessments of family satisfaction between cohabitors and spouses have eroded over the years and that there has been no detectable cohabitation gap since 2011. In addition, we illustrate that the weakening of the cohabitation gap is attributable to the diffusion of cohabiting unions in Italian society.     

Socioeconomic Inequalities and Self-Rated Health: A Multilevel Study of Italian Elderly

We adopted a multilevel approach in order to provide a comprehensive overview of the main social and economic differences associated with inequalities in self-rated health, according to the territorial context of residence. We focused on the Italian population aged 65 and over, availing of the most recent data on health conditions in Italy. This study proves the persistence in Italy, a modern welfare state that has one of the best overall healthcare systems in the world, of significant, if not enormous, socioeconomic differences in self-perceived health among the elderly. We found that each component of the socioeconomic status is autonomously correlated with individual perceptions of health, highlighting the importance of considering all of the facets of the individual socioeconomic status in measuring the extent of health inequalities. The lack of a network of relationships was also found to be strongly associated with a poor health status for elderly Italians. Our study also documented the presence of a contextual effect. The proposed multilevel modeling proved to be useful in shedding light on relevant aspects in the field of perceived health and for avoiding misleading results.     

Seasonal dynamics of bird communities in urban forests of a Mediterranean city (Montpellier,Southern France)

We evaluated the richness, composition and abundance of bird communities in three urban forests of Mediterranean France during winter and spring. The urban forests differed in size, composition, structure, age of vegetation, and location relative to the city centre. Estimated species richness across all three urban forest parks was 45 species. Twenty six (26) species were recorded in both winter and spring, whereas ten species were recorded only in spring, and six were recorded only in winter. Distribution, turnover, and type of bird foraging guild were related to characteristics of each urban forest and season. During spring migration, more species were recorded in sampling units (250?×?250 m) within the largest and most natural urban forest located in the outskirts of Montpellier, whereas during winter, more species were recorded in the most urbanized park (i.e., a botanical garden dominated by exotic vegetation), which was located in the city centre. Insectivorous birds were more abundant in winter, whereas seedeaters associated with wooded habitats were recorded more frequently in spring. Our results suggested that different kinds of urban forests are important modulators of urban bird communities and they are necessary to maintain the diversity of migratory and resident birds as well as increasing the environmental quality of urban areas.     

Measuring Socio-Demographic Differences in Volunteers with a Value-Based Index: Illustration in a Mega Event

The phenomenon of volunteering can be analysed as a consumer experience through the concept of value as a trade-off between benefits and costs. In event volunteering, both the expected value (pre-experienced) and the perceived value (post-experienced) of volunteering can be assessed. With this purpose, an online quantitative survey is conducted with a sample of 711 volunteers in a religious mega event, with questions related to five dimensions of their experience: efficiency, social value, play, spirituality and time spent. These five scales, properly tested are used for building a multidimensional index of both the expected and perceived value of the volunteer experience. ANOVAs test show significant differences on the index in both moments upon the socio-demographic profiles: negative expectations/experience balance by age, contrasted results by sex, and more experienced volunteers being more critical with the value experienced. Implications for event managers are proposed, in line with the motivation of volunteers.     

Levels of uric acid in erectile dysfunction of different aetiology

Erectile dysfunction is a common disease characterized by endothelial dysfunction. The aetiology of ED is often multifactorial but evidence is being accumulated in favor of the proper function of the vascular endothelium that is essential to achieving and maintaining penile erection. Uric acid itself causes endothelial dysfunction via decreased nitric oxide production. This study aims to evaluate the serum uric acid (SUA) levels in 180 ED patients, diagnosed with the International Index of Erectile Function-5 (IIEF-5) and 30 non-ED control. Serum uric acid was analyzed with a commercially available kit using ModularEVO (Roche, Monza, Italy). Within-assay and between-assay variations were 3.0% and 6.0%, respectively. Out of the ED patients, 85 were classified as arteriogenic (A-ED) and 95 as non-arteriogenic (NA-ED) with penile-echo-color-Doppler. Uric acid levels (median and range in mg/dL) in A-ED patients (5.8, 4.3–7.5) were significantly higher (p?p?相似文献   

The Decision of the Supply Chain Executive to Support or Impede Supply Chain Integration: A Multidisciplinary Behavioral Agency Perspective*

Applying the behavioral agency model developed by Wiseman and Gomez‐Mejia (1998) , this article analyzes human resource factors that induce supply chain executives (SCEs) to make decisions that foster or hinder supply chain integration. We examine two internal sources (compensation and employment risk) and one external source (environmental volatility) of risk bearing that can make SCEs more reluctant to make the decision to promote supply chain integration. We argue and empirically confirm the notion that an employment and compensation system that increases SCE risk bearing reduces the SCE's willingness to make risky decisions and thus discourages supply chain integration. We also reveal that this negative relationship becomes stronger under conditions of high environmental volatility. In addressing the “so what?” question, we found empirical support for the hypothesis that supply chain integration positively influences operational performance. Even though this decision has a positive value for the firm, we showed that SCEs discourage supply chain integration when they face higher risk bearing. Hypotheses are tested using a combination of primary survey data and archival measures in a sample of 133 Spanish firms.     

The facility location problem with Bernoulli demands

This paper presents the facility location problem with Bernoulli demands. In this capacitated discrete location stochastic problem the goal is to define an a priori solution for the locations of the facilities and for the allocation of customers to the operating facilities that minimizes the sum of the fixed costs of the open facilities plus the expected value of the recourse function. The problem is formulated as a two-stage stochastic program and two different recourse actions are considered. For each of them, a closed form is presented for the recourse function and a deterministic equivalent formulation is obtained for the case in which the probability of demand is the same for all customers. Numerical results from computational experiments are presented and analyzed.
