The idea that people matter in modern democracies, often referred to as 'civic engagement' is recognised at the highest international level (United Nations 2008: 9). Civic or community engagement is essential to how budgets are decided, policy is developed and public services delivered. Significantly, community engagement is crucial in developing policy for sustained economic and social development. In Ireland the idea of the Developmental Welfare State (DWS) is based on the premise that the social policy system should support citizens so as to reach their full potential. Such a system comprises three overlapping elements: tax and welfare transfer, the provision of services and activist initiatives (National Economic and Social Council, 2005: ix-xviii). Civil Society Organisations have been challenged to 'operationalise the DWS' using a 'life cycle framework' as part of Ireland's corporatist partnership model (Department of Taoiseach, 2006: 40).

Going beyond the association between youth exposure to political violence and psychopathology, the current article examines within-person change in youth strength of identity with their ethno-political group and youth reports of the insecurity in their communities. Conceptually related but growing out of different paradigms, both group identity and emotional insecurity have been examined as key variables impacting youth responses to threats from other group members. The goal of the current study is to review previous studies examining these two key variables and to contribute new analyses, modeling within-person change in both variables and examining covariation in their growth. The current article uses data from 823 Belfast adolescents over 4 years. The results suggest youth are changing linearly over age in both constructs and that there are ethno-political group differences in how youth are changing. The results also indicate that change in insecurity is related to strength of identity at age 18, and strength of identity and emotional insecurity are related at age 18. Implications and directions for future work in the area of youth and political violence are discussed. © 2014 American Psychological Association.

Although regret is assumed to facilitate good decision making, there is little research directly addressing this assumption. Four experiments (N = 326) examined the relation between children's ability to experience regret and the quality of their subsequent decision making. In Experiment 1 regret and adaptive decision making showed the same developmental profile, with both first appearing at about 7 years. In Experiments 2a and 2b, children aged 6–7 who experienced regret decided adaptively more often than children who did not experience regret, and this held even when controlling for age and verbal ability. Experiment 3 ruled out a memory-based interpretation of these findings. These findings suggest that the experience of regret facilitates children's ability to learn rapidly from bad outcomes.

This paper provides an outline of the development of temporal thinking that is underpinned by the idea that temporal cognition shifts from being event dependent to event independent over the preschool period. I distinguish between three different ways in which it may be possible to have a perspective on time: (1) a perspective that is grounded in script-like representations of repeated events; (2) a more sophisticated perspective that brings in an fundamental categorical distinction between events that have already happened and events that are yet to come; and (3) a mature temporal perspective that involves orienting oneself in time using a linear temporal framework, with a grasp of the distinctions between past, present, and future. I propose that, with development, children possess each of these types of perspective in turn, and that only the last of these involves being able to represent time in an event-independent way.

This paper attempts to situate and deconstruct the meanings associated with the term development in the context of the developing world. The arguments made highlights the deeply contested and fragmented terrain of development. The paper provides a historical overview of the changing nature of discourses on development, how the imageries of development have shifted since the postwar period. It deploys diverse meanings associated with development as a concept and as a theory. Thus development without dignity means little for those living in the margins of the society. At the same time the language of development has undergone revolutions and convulsions and the role of buzzwords and catch phrases have only helped to prolong misery in a neoliberal world. Development has become a 'one size fits all' concept shorn of cultural and regional specificities. It has been decontextualised and dehumanised to relate to targets
resulting in greater dissonance than resolution of aim and outcomes. The way forward is a better appreciation of the cultural capacity of the social groups for whom development is critical for survival. The conclusion highlights the endemic contradictions inherent in the meaning and delivery of development as a goal, especially when we seek to achieve resilient and sustainable development.

OBJECTIVE: The antitumor effects of FK506-binding protein like (FKBPL) and its extracellular role in angiogenesis are well characterized; however, its role in physiological/developmental angiogenesis and the effect of FKBPL ablation has not been evaluated. This is important as effects of some angiogenic proteins are dosage dependent. Here we evaluate the regulation of FKBPL secretion under angiogenic stimuli, as well as the effect of FKBPL ablation in angiogenesis using mouse and zebrafish models.
APPROACH AND RESULTS: FKBPL is secreted maximally by human microvascular endothelial cells and fibroblasts, and this was specifically downregulated by proangiogenic hypoxic signals, but not by the angiogenic cytokines, VEGF or IL8. FKBPL's critical role in angiogenesis was supported by our inability to generate an Fkbpl knockout mouse, with embryonic lethality occurring before E8.5. However, whilst Fkbpl heterozygotic embryos showed some vasculature irregularities, the mice developed normally. In murine angiogenesis models, including the ex vivo aortic ring assay, in vivo sponge assay, and tumor growth assay, Fkbpl(+/-) mice exhibited increased sprouting, enhanced vessel recruitment, and faster tumor growth, respectively, supporting the antiangiogenic function of FKBPL. In zebrafish, knockdown of zFkbpl using morpholinos disrupted the vasculature, and the phenotype was rescued with hFKBPL. Interestingly, this vessel disruption was ineffective when zcd44 was knocked-down, supporting the dependency of zFkbpl on zCd44 in zebrafish.
CONCLUSIONS: FKBPL is an important regulator of angiogenesis, having an essential role in murine and zebrafish blood vessel development. Mouse models of angiogenesis demonstrated a proangiogenic phenotype in Fkbpl heterozygotes.
