Academic interest in the work of family centres in the United Kingdom has largely been concerned with categorising the work of such centres in terms of issues of childcare ideology, working practices and degree of service user control. Meanwhile, the re-focusing of child protection services in order to develop child welfare services has largely dominated childcare social work in recent years, with scant attention paid to the role of family centres in relation to this debate. This study is concerned with examining the perspectives of staff and service users in five 'client focussed' family centres in Northern Ireland in relation to how child protection issues are understood and dealt with. It was found that staff enter into negotiations with both referrers and service users to conceptually reframe child protection work as family support practice. This leads to the development of partnership relationships between staff and service users based upon mutual high regard. The work of such centres leaves them well placed to provide integrated services to children in need in line with current government priorities, but could leave some children vulnerable where child protection issues are not amenable to conceptual reframing along family support lines.

The introduction of the Quality Protects initiative in England and the focus on performance management has challenged social services departments to examine the systems, processes and outcomes for children who have their name on a child protection register. Research indicates that approximately one-quarter of the situations in which children are registered could be described as chronic—that is, they remain on the child protection register for significant periods of time, experience more than one period of registration or suffer a further incident of significant harm whilst subject to a child protection plan. In this article, the findings from a research study conducted into this group of vulnerable children are reported, focusing on the characteristics of the children and their families, and their careers in the child protection system. The paper concludes with observations about the weak conceptualization of performance management and the need to recognize the complexity of the factors that influence children’s careers in the child protection system.

The structural diversity of polypeptides in amphibian skin secretion probably reflects different roles in dermal regulation or in defense against predators. Here we report the structures of two novel trypsin inhibitor analogs, BOTI and BVTI, from the dermal venom of the toads, Bombina orientalis and Bombina variegata. Cloning of their respective precursors was achieved from lyophilized venom cDNA libraries for the first time. Amino acid alignment revealed that both deduced peptides, consisting of 60 amino acid residues, including 10 cysteines and the reactive center motif, -CDKKC-, can be affirmed as structural homologs of the trypsin inhibitor from Bombina bombina skin.

Fire has long been recognized as an agent of rock weathering. Our understanding of the impact of fire on stone comes either from early anecdotal evidence, or from more recent laboratory simulation studies, using furnaces to simulate the effects of fire. This paper suggests that knowledge derived from simulated heating experiments is based on the preconceptions of the experiment designer – when using a furnace to simulate fire, the operator decides on the maximum temperature and the duration of the experiment. These are key factors in determining the response of the stone to fire, and if these are removed from realworld observations then knowledge based on these simulations must be questioned. To explore the differences between heating sandstone in a furnace and a real fire, sample blocks of Peakmoor Sandstone were subjected to different stress histories in combination (lime rendering and removal, furnace heating or fire, frost and salt weathering). Block response to furnace heating and fire is discussed, with emphasis placed on the non-uniformity of the fire and of block response to fire in contrast to the uniform response to surface heating in a furnace. Subsequent response to salt weathering (by a 10% solution of sodium chloride and magnesium sulphate) was then monitored by weight loss. Blocks that had experienced fire showed a more unpredictable response to salt weathering than those that had undergone furnace heating – spalling of corners and rapid catastrophic weight loss were evidenced in blocks that had been subjected to fire, after periods of relative quiescence. An important physical side-effect of the fire was soot accumulation, which created a waxy, relatively impermeable layer on some blocks. This layer repelled water and hindered salt ingress, but eventually detached when salt, able to enter the substrate through more permeable areas, concentrated and crystallized behind it, resulting in rapid weight loss and accelerated decay.
