En este estudio se examina la relación entre el comportamiento reproductivo y algunas características de la nupcialidad en el Brasil, sobre la base de datos de las Encuestas de Demografía y Salud (Demographic and Health Survey (DHS)) de 1986 y 1996 y de la Encuesta Nacional de Demografía y Salud de la Infancia y la Mujer (PNDS) de 2006. Los resultados indican que el nivel de fecundidad de las mujeres que viven en uniones consensuales es un poco más elevado que el de las que optan por el matrimonio. Sin embargo, también se constata un movimiento de convergencia entre los niveles de fecundidad de ambos grupos. Para establecer el aporte de cada tipo de unión al cálculo de la fecundidad total se aplica la descomposición de la tasa de fecundidad. Además de aumentar la proporción de las uniones consensuales a lo largo del tiempo, crece también la participación de este tipo de unión en la fecundidad total. Se argumenta que el significado de tener hijos ha cambiado y que, en el caso brasileño, las uniones consensuales pueden comprenderse mejor a la luz de la teoría de la institucionalización.

El objetivo de este trabajo es analizar el efecto de los crecientes niveles educativos en los patrones de formación de las primeras uniones en el siglo XX en México. Para ello se analizan la edad al momento de la unión, el tipo de unión (matrimonio o unión consensual) y la residencia de la pareja recién formada (hogar independiente o permanencia en el hogar familiar). Los ejes analíticos son el género, el estrato social y la cohorte. La fuente de datos es la Encuesta Nacional sobre la Dinámica de las Familias (ENDIFAM) de 2005. Se estiman modelos de tiempo discreto: regresión logística y de riesgos en competencia. Se observa que la asistencia a la escuela y la escolaridad propician la postergación de la formación de la primera unión en general y de las uniones consensuales en particular, y reducen la probabilidad de que las parejas permanezcan en el hogar familiar. Sin embargo, esto ocurre por vías muy distintas en el caso de hombres y mujeres y varía según las cohortes de nacimiento y los estratos sociales de origen.

The purpose of this paper is to explore the changing nature of employee voice through trade union representation in the retail industry. The retail industry is a major employer in the UK and is one of the few private sector service industries with union representation (Griffin et al 2003). The requisite union: the Distributive and Allied Workers (USDAW) union is one of the biggest unions in the country. However, the characteristics of the industry provide unique challenges for employee voice and representation including: high labour turnover; high use of casual, female and student labour; and, variable levels of union recognition (Reynolds et al 2005). Irrespective of these challenges, any extension of representation and organisation by unions in the retail sector is inherently valuable, socially and politically, given that retail workers are often categorised as vulnerable, due to the fact that they are among the lowest paid in the economy, sourced from disadvantages labour markets and increasingly subject to atypical employment arrangements (Broadbridge 2002; Henley 2006; Lynch 2005; Roan 2003).

This paper is a comparative exploratory study of the changing nature of employee voice through trade union representation in the retail industry in the UK and Australia. In both countries, the retail industry is a major employer and is one of the few private sector service industries with significant union membership (Griffin et al 2003). The relevant unions, the Distributive and Allied Workers Union (USDAW) and the Shop, Distributive and Allied Union (SDA), are the fourth largest and largest unions in the UK and Australia respectively. However, despite this seeming numerical strength in membership, the characteristics of the industry provide unique challenges for employee voice and representation. The significance of the study is that any extension of representation and organisation by unions in the retail sector is valuable socially and politically, given that retail workers are often categorised a s vulnerable, due to their low pay, the predominance of disadvantaged labour market groups such a s women and young people, workers’ atypical employment arrangements and, in the case of the UK, variable levels of union recognition which inhibit representation (Broadbridge 2002; Henley 2006; Lynch 2005; Roan & Diamond 2003; Reynolds et al 2005). In addition, specifically comparative projects have value in that they allow some variables relating to the ‘industry’ to be held constant, thus reducing the range of potential explanations of differences in union strategy. They also have value in that the research partners may be more likely to notice and problematise taken-for-granted aspects of practices in another country, thus bringing to the fore key features and potentially leading to theoretical innovation. Finally, such projects may assist in transnational diffusion of union strategy.

In this chapter, ideas from ecological psychology and nonlinear dynamics are integrated to characterise decision-making as an emergent property of self-organisation processes in the interpersonal interactions that occur in sports teams. A conceptual model is proposed to capture constraints on dynamics of decisions and actions in dyadic systems, which has been empirically evaluated in simulations of interpersonal interactions in team sports. For this purpose, co-adaptive interpersonal dynamics in team sports such as rubgy union have been studied to reveal control parameter and collective variable relations in attacker-defender dyads. Although interpersonal dynamics of attackers and defenders in 1 vs 1 situations showed characteristics of chaotic attractors, the informational constraints of rugby union typically bounded dyadic systems into low dimensional attractors. Our work suggests that the dynamics of attacker-defender dyads can be characterised as an evolving sequence since players' positioning and movements are connected in diverse ways over time.

In the region of self-organized criticality (SOC) interdependency between multi-agent system components exists and slight changes in near-neighbor interactions can break the balance of equally poised options leading to transitions in system order. In this region, frequency of events of differing magnitudes exhibits a power law distribution. The aim of this paper was to investigate whether a power law distribution characterized attacker-defender interactions in team sports. For this purpose we observed attacker and defender in a dyadic sub-phase of rugby union near the try line. Videogrammetry was used to capture players’ motion over time as player locations were digitized. Power laws were calculated for the rate of change of players’ relative position. Data revealed that three emergent patterns from dyadic system interactions (i.e., try; unsuccessful tackle; effective tackle) displayed a power law distribution. Results suggested that pattern forming dynamics dyads in rugby union exhibited SOC. It was concluded that rugby union dyads evolve in SOC regions suggesting that players’ decisions and actions are governed by local interactions rules.

- Background Substance use is common among gay/bisexual men and is associated with significant health risks (e.g. HIV transmission). The consequences of substance use, across the range of substances commonly used, have received little attention. The purpose of this study is to map participant’s beliefs about the effects of substance use to inform prevention, health promotion and clinical interventions. - Methods Participants were interviewed about experiences regarding their substance use and recruited through medical and sexual health clinics. Data were collected though a consumer panel and individual interviews. Responses regarding perceived consequences of substance use were coded using Consensual Qualitative Research (CQR) methodology. - Results Most participants reported lifetime use of alcohol, cannabis, stimulants and amyl nitrite, and recent alcohol and cannabis use. A wide range of themes were identified regarding participant’s thoughts, emotions and behaviours (including sexual behaviours) secondary to substance use, including: cognitive functioning, mood, social interaction, physical effects, sexual activity, sexual risk-taking, perception of sexual experience, arousal, sensation, relaxation, disinhibition, energy/activity level and numbing. Analyses indicated several consequences were consistent across substance types (e.g. cognitive impairment, enhanced mood), whereas others were highly specific to a given substance (e.g. heightened arousal post amyl nitrite use). - Conclusions Prevention and interventions need to consider the variety of effects of substance use in tailoring effective education programs to reduce harms. A diversity of consequences appear to have direct and indirect impacts on decision-making, sexual activity and risk-taking. Findings lend support for the role of specific beliefs (e.g. expectancies) related to substance use on risk-related cognitions, emotions and behaviours.
