Contagion of Anxiety Symptoms Among Adolescent Siblings: A Twin Study

This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic and dizygotic twins (336 females) assessed in Grades 6 and 7, anxiety symptoms and sibling relationship quality were measured with self‐report questionnaires. The predictive association of the co‐twin's level of anxiety with adolescents' own increased anxiety 1 year later was only observed in same‐sex twin dyads (monozygotic and dizygotic) and was higher for those who perceived a higher level of relationship quality with their co‐twin. Raising awareness of a possible sibling contagion of anxiety may be useful for preventing the development of anxiety symptoms in youth.     

Ergonomic assessment of porridge roaming sale system

This paper makes suggestions for the realization of an ergonomic intervention, guided by the method of Moraes and Mont'Alv?o (2009), in the system of street vending of porridge, to improve the working conditions of this sales segment. Specifics are given about this practice and its problems, from ergonomic analysis comes to suggestions for improvements to be applied to a new system.     

Las políticas de igualdad en el ‘welfare mix’: opiniones y percepciones sobre el papel de las ONGs

This paper has been structured in three areas. In the first one, the author shows the relevance that words and conversations among individuals have on social research, both terms being very important to the well-known sociologist and writer Franco Ferrarotti. In the second part, the author explains the necessary qualitative methodology to be used when analysing a main topic. In the third one, the author analyses the reality of non-governmental organisations (NGOs) from the gender perspective to detect if they are or not a reflection of that Spanish reality regarding sex discrimination. Finally, this paper states the challenge the Spanish society needs to face to outweigh sex inequality without excluding the NGOs or any other form of association. This paper calls for the involvement of society, which along with the state and market, has an important task to accomplish.     

AIDS victims and heterosexual attitudes

This study reports on the development of a Likert scale that measures attitudes toward AIDS victims (ATAV) in five phases. A total of 582 undergraduate (means age = 24.2) completed the survey forms, 249 males and 333 females. The results for Phase 1 yielded a scale with high part-whole correlations (.62-.90, p less than .001), corrected split-half reliability (.87, p less than .001), and alpha coefficients (.91, p less than .001). The following phases yielded significant correlations between the ATAV scale and attitudes toward homosexuals (.60, p less than .001), homosexual parenting (.64, p less than .001), other minority groups (.33, .37, p less than .001), capital punishment (-.27 p less than .001), and sexually liberal attitudes (.22, .37, .23, p, less than .025). Attitudes toward homosexuals are the central component in attitudes toward AIDS victims. A varimax rotated factor analysis of the ATAV yielded one primary factor accounting for 85.9% of the variance.     

Does country-risk influence electricity production worldwide?

This paper investigates the relationship between country-risks (or conflicts) within countries and electricity production. The determinants of electricity production have been neglected in the literature that favours the relationship between energy consumption, growth and development, and despite of the major challenges on electricity supply systems. We empirically establish that weighted conflict index, as well as sub-items as anti-government demonstrations, government crises and riots negatively influence electricity production per capita, after controlling for income per capita. Country conflicts affect electricity production mostly in the long-run. Our results imply that conflicts may affect electricity production substantially and consequently the economy as a whole. Policy should emphasize the institutional framework to avoid conflicts within countries in order to secure electricity production.     

Corporate governance and management practices: stakeholder involvement, quality and sustainability tools adoption

Local public services are the field in which New Public Management (NPM) and Public Governance issues are most in evidence. The local public services are characterized by the rethinking of the role played by local government in the provision of services. An evolution has taken place. From a traditional configuration in which local public services were managed by local governments they moved to a configuration where a separation has taken place between the local government role (which continues to be the guarantor of the satisfaction of public needs) and the role of local public utilities (LPUs) (responsible for delivering the services). This transformation implies both the delegation of resources and authority to lower organisational levels within the public sector and the reconfiguration of accountability chains between the state institutions and the society. In recent years, an intense debate has developed regarding the introduction of new tools and control systems. Particular attention has been paid to planning and control systems, human resources management systems, and performance management systems, leaving a few pioneers to develop their analysis on corporate governance mechanisms with regard their relationships with both the external (stakeholders) actors and the internal (management) ones. On one hand, the OECD wrote guidelines in order to ensure good corporate governance practices, focusing on relations with stakeholders. On the other hand, the dialogue between corporate governance and stakeholders has been already tackled by a number of International organizations guidelines or principles, following a debate on corporate governance that has progressively combined a stakeholder perspective with a more classic shareholder-maximizing model of governance. This article contributes to the debate on the stakeholder involvement process. By means of both a theoretical discussion and an empirical research conducted on 37 Italian LPUs, this paper attempts to analyse specific management tools which can be used to improve the quality of corporate governance in LPUs, by extending the stakeholder involvement. Some NPM’s tools, such as quality standards and sustainability tools imply an effort to offer new forms of organizational behaviour in the decision-making processes (i.e. the choice of the performance indicators and the reporting tools) and to create a dialogue between the enterprise and its stakeholders. In particular, in our study we focus on the adoption of quality standards (ISO 9000 and Customer Satisfaction) and sustainability tools (sustainability reports and ISO 14000 standard) as NPM’s tools to facilitate the stakeholder involvement practices.
