VOLUNTARY ACTIVITIES AND DAILY HAPPINESS IN THE UNITED STATES

This article analyzes differences in daily happiness between those individuals in the United States who perform voluntary activities during the day and those who do not. Using the Well‐Being Module of the American Time Use Survey 2010, we find that those who devote any time to voluntary activities during the day report higher levels of daily happiness than those who do not. Comparing the happiness obtained from a range of activities, we find that volunteering is among the most enjoyable, indicating that time spent on voluntary activities is utility‐enhancing. We document that the effect of voluntary activities on the experienced utility of individuals can be decomposed into a “time‐composition” effect and an “activity” effect, with the latter explaining between 11% and 46% of the observed difference.

Relationships and identity of gay men in Mexico: A qualitative approach

Relationships are a fundamental element of human and social interactions because they provide us with meanings around physical and abstract objects that allow us to make sense of our reality and identities. There is little Mexican research regarding how gay men construct a sense of identity through their social interactions. This article describes the relationships that gay men in Mexico City have within their families, with their friends, and with their partners. Fifteen in-depth interviews are analyzed through elements of Grounded Theory and Critical Discourse Analysis. Results show that family reproduced homophobia with participants that taught them that their gay identity is socially unaccepted. This is deconstructed through friendships with other gay men. Partner relationships are lived as one of the last milestones in the construction of a gay identity. Some men question hegemonic values around sexuality through polyamorous and polygamous relationships. Conclusions show the importance of these social relationships for gay men's emotional well-being, but that their relationships are often impacted by cultural and interpersonal homophobia.     

The Drivers of Voluntary Transparency in Nonprofits: Professionalization and Partnerships with Firms as Determinants

This research analyzes the drivers of voluntary transparency in nonprofit organizations (NPOs). Particularly, we assess the influence of key internal and external resource providers—paid staff and business partners—on the extent to which NPOs make accessible relevant information about themselves for public scrutiny on a voluntary basis. First, we conceptualize transparency as one of the critical dimensions of accountability and explain how it has become a key issue for NPOs. Second, we discuss professionalization and business–nonprofit partnerships as business-oriented strategies directly connected to the main challenges (and controversies) NPOs face. Third, following institutional theory as core theoretical framework, we propose a set of hypotheses linking those strategies to transparency. Their influence will be measured through an empirical research based on a survey to a representative sample of 325 NPOs. Regression analysis and probit models will be used to test the hypotheses. The results confirm the positive effects of both professionalization and partnerships, although each strategy influences different dimensions of transparency.     

The Wage Gap between Foreign and Spanish Nationals in Spain: an Analysis Using Matched Employer–Employee Data

In this paper, we analyse wage differences between foreign and Spanish nationals in Spain. This analysis is relevant because Spain has witnessed a sharp increase in the proportion of foreign workers over the past decade. In our analysis, we explicitly account for unobserved heterogeneity at firm level, a situation which occurs when relevant covariates (for example, those connected to a specific firm's production process) are not included in the model because they are unmeasurable, unobservable or unavailable for the researcher. When accounting for such heterogeneity, our results show that wage gaps between foreign nationals from developing countries and Spanish nationals range between ?6.35 per cent and ?11.30 per cent. We also find that wage differences, between Spanish nationals and others in the same firm and job, are substantially greater for almost every group of low‐tenured foreign workers and also for those holding open‐ended contracts.     

Field Placement and the Impact of Financial Stress on Social Work and Human Service Students

While significant research has been undertaken exploring the pedagogical benefits of undertaking lengthy social work and human services field placements, there has been very little consideration given to the potential financial stress involved for students. This study sought to address this knowledge gap. Research was conducted in 2014 using quantitative and qualitative methods with students and academic and professional staff from six Queensland universities. The findings show a significant relationship between unpaid placements and financial hardship, creating considerable stress for students and at times a compromised placement learning experience. The limited flexibility in requirements from professional bodies and universities for how placements are undertaken has been identified as a key contributor to financial hardship. Addressing the complexities inherent in this issue requires a collaborative effort from multiple stakeholders and should not be regarded as a problem for students to endure and manage.     

Satisfacción residencial en un barrio remodelado: Predictores físicos y sociales

Resumen

El trabajo que aquí se presenta consiste en una investigación llevada a cabo en un área de remodelación, con dos objetivos primordiales: Por un lado, comprobar en que medida las categorías de «casa», «barrio» y «vecinos» son dimensiones importantes para el estudio de satisfacción residencial; y en segundo lugar, encontrar predictores físicos y sociales de dicho constructo a través de un instrumento válido a tal fin. Los resultados obtenidos en una muestra de 232 amas de casa, confirman la relevancia de las categorías mencionadas anteriormente. En cuanto al segundo objetivo, un análisis de regresión multiple pone de manifiesto que son cuatro los factores que más explican la satisfacción residencial en este área concreta, siendo el «aislamiento térmico» el más importante de ellos.     

Testosterone and men's quality of life

As the worldwide population ages, the emphasis on having a reasonable quality of life in old-age is increasing. In men, age-associated testosterone decline is one of the major factors that reduce quality of life. In patients and the physicians treating them, decreased energy levels and impairments to sex-life are perceived as the most important effects of hypogonadism. Two quality of life scales, the Aging Males' Symptoms (AMS) and the Age-Related Hormone Deficiency-Dependent Quality of Life (A-RHDQoL) scales, have recently been developed to specifically assess this patient population, and the A-RHDQoL found that memory, energy and physical capabilities, and sex-life were the factors most adversely affected by low testosterone levels. Unfortunately, there are limited data on the effects of testosterone on the quality of life of men with hypogonadism, but the information that exists suggests that testosterone can improve the quality of life significantly (to the same level as men with normal testosterone levels) and the more severe the symptoms before treatment, the greater the benefits of testosterone replacement. These promising early results need to be confirmed in more detailed quality of life studies.     

Convergence criteria for interval-valued inequality indices

In this paper we introduce an interval-valued inequality index for random intervals based on a convex function. We show that if this function does not grow faster than x ^p , then the inequality index is continuous on the space of random intervals with finite p-th moment. A bound for the distance between the inequality indices of two random intervals is also constructed. An example is presented to motivate and illustrate the developments in this paper.     

Automatic Specification Testing for Vector Autoregressions and Multivariate Nonlinear Time Series Models

This article introduces an automatic test for the correct specification of a vector autoregression (VAR) model. The proposed test statistic is a Portmanteau statistic with an automatic selection of the order of the residual serial correlation tested. The test presents several attractive characteristics: simplicity, robustness, and high power in finite samples. The test is simple to implement since the researcher does not need to specify the order of the autocorrelation tested and the proposed critical values are simple to approximate, without resorting to bootstrap procedures. In addition, the test is robust to the presence of conditional heteroscedasticity of unknown form and accounts for estimation uncertainty without requiring the computation of large-dimensional inverses of near-to-singularity covariance matrices. The basic methodology is extended to general nonlinear multivariate time series models. Simulations show that the proposed test presents higher power than the existing ones for models commonly employed in empirical macroeconomics and empirical finance. Finally, the test is applied to the classical bivariate VAR model for GNP (gross national product) and unemployment of Blanchard and Quah (1989 Blanchard, O. and Quah, D. 1989. “The Dynamic Effects of Aggregate Demand and Supply Disturbances,”. The American Economic Review, 79: 655–673. [Web of Science ®] , [Google Scholar]) and Evans (1989 Evans, G. W. 1989. “Output and Unemployment Dynamics in the United States: 1950–1985,”.

Coalitional Interval Games for Strategic Games in Which Players Cooperate

We propose a method to associate a coalitional interval game with each strategic game. The method is based on the lower and upper values of finite two-person zero-sum games. Associating with a strategic game a coalitional interval game we avoid having to take either a pessimistic or an optimistic approach to the problem. The paper makes two contributions to the literature: It provides a theoretical foundation for the study of coalitional interval games and it also provides, studies, and characterizes a natural method of associating coalitional interval games with strategic games.
