Transition in practice and action in research. A French case study in piloting eco-innovations

Transition in practice means that diverse organizations – from private foundations to citizen-led movements for “cities in transition” – are experiencing ways to bring about sustainable transitions at the system level. While academic thinking on sustainability transitions can efficiently inform transition in practice, these organizations' initiatives can enrich the analytic understanding of transitions. It is this mutually beneficial trade-off that became the purpose of the action research project with the French private foundation Fondaterra, and which led to the drafting of Fondaterra's own model in piloting eco-innovations towards transition. This paper outlines the main features of the Fondaterra model: the territorial perspective, the idea of piloting change, espousing prospective visions, creating new chains of value, implementing demonstrators and monitoring. The comparison of this model with the transition management model suggests that the latter may resonate with other intervention methodologies that have been developed with strong concern for governance strategies, and that many configurations of transition in practice led by intermediary organizations could achieve tangible results in triggering transitions.     

K–Player Additive Extension of Two-Player games with an Application to the Borda Electoral Competition Game

In this note we introduce the notion of K–player additive extension of a symmetric two-player game and prove a result relating the equilibria in mixed strategies in the two games. Then we apply the result to the Borda electoral competition game.     

Domestic violence and child protection: issues in safety planning

There is strong evidence for the link between domestic violence and child abuse. Agencies' policies regarding domestic violence and child protection are critical in determining the dimensions of practitioner intervention, including safety planning for women and children. This paper explores the issues identified in research around safety planning where there are domestic violence and child protection concerns which was conducted with practitioners in New South Wales (NSW), Australia, in 2001. In particular, the paper focuses on three of the factors that influence practitioner intervention with women and children. These are: definitional understandings of domestic violence and child abuse; child protection legislative changes, including mandatory reporting and domestic violence as a child‐at‐risk category; and the NSW child protection statutory authority's response to domestic violence. The interplay between these factors results in complexities of practice for practitioners as they attempt to maximize women's strengths and minimize risks to children's safety. The resultant inconsistent response to domestic violence and child protection by government and non‐ government agencies suggests the need for domestic violence interagency guidelines.

Do spouses cooperate? An experimental investigation

This study makes a significant contribution to investigations of household behavior by testing for a willingness to cooperate and share income by men and women who are either in couple with each other or complete strangers. We present results from an economic experiment conducted with 100 co-habiting heterosexual couples. We compare defection behavior in the prisoner’s dilemma within real couples to pairs of strangers. One out of four participants chose not to cooperate with their spouse. To understand why spouses might prefer defection, we use a novel allocation task to elicit the individual’s trade-off between efficiency and equality within a couple. We further investigate the impact of socio-demographic and psychological characteristics of the couples. We find in particular that lack of preferences for joint income maximization, having children and being married lead to higher defection rates in the social dilemma.     

Thermal,viscoelastic and mechanical properties' optimization of polyphenylene sulfide via optimal processing parameters using the Taguchi method

Thermal, viscoelastic and mechanical properties of polyphenylene sulfide (PPS) were optimized as a function of extrusion and injection molding parameters. For this purpose, design of experiments approach utilizing Taguchi's L₂₇ (3⁷) orthogonal arrays was used. Effect of the parameters on desired properties was determined using the analysis of variance. Differential scanning calorimeter (DSC) tests were performed for the analysis of thermal properties such as melting temperature (T_m) and melting enthalpy (ΔH_M). Dynamic mechanical analysis (DMA) tests were performed for the analysis of viscoelastic properties such as damping factor (tan?δ) and glass transition temperature (T_g). Tensile tests were performed for the analysis of mechanical properties such as tensile strength and modulus. With optimized process parameters, verification DSC, DMA and tensile tests were performed for thermal, viscoelastic and mechanical properties, respectively. The Taguchi method showed that ‘barrel temperature’ and its level of ‘340°C’ were seen to be the most effective parameter and its level; respectively. It was suggested that PPS can be reinforced for further improvement after optimized thermal, viscoelastic and mechanical properties.     

Researching Within‐Household Distribution: Overview,Developments, Debates,and Methodological Challenges

Research into intrahousehold finances challenges key assumptions about the family as a unitary whole, investigates the extent of sharing within it, examines mechanisms of control and allocation of resources, and reveals the personalized nature of different monies. This article presents an overview of research on within‐household distribution (understood as both outcome and process). It discusses major questions addressed, including inequalities between (gendered) individuals and the potential reasons for these. It outlines significant developments and debates, within qualitative research in particular, in relation to the unit of analysis (traditionally, the married couple), the texture and meaning of financial dealings within couples, and the tensions between autonomy and equal sharing as values. It then discusses several key methodological challenges, and concludes by highlighting some policy implications of central research messages. Throughout, it draws on and discusses the other articles in this special section, which explore key methodological issues in researching within‐household distribution.
