Correlating Additives to Deterioration and Assessing the Effectiveness of Acrylic Coatings for the Protection of Rubber

Conservators have long been aware of the problems associated with the preservation of rubber objects due to inherent instability that can be attributed, in part, to the presence of additives. Inorganic additives, such as fillers, accelerators, stabilizers, and special ingredients are necessary in manufacturing to alter the properties of natural rubber. These materials all have different interactions with the rubber, and each other, and differing effects on the ageing process. To date, the most effective and accepted methods to preserve rubber are cold, dark storage of objects, or the use of low oxygen environments. While these methods are effective, they greatly limit access. The application of coatings to the surface of rubber objects can slow deterioration and greatly increase the ability of an institution to handle and display rubber objects. While numerous coatings for preventive and interventive treatment have been tested, none have been so successful to warrant routine use. The first section of this research highlighted the relationship between the inclusion of certain additives in natural rubber objects and the accelerated or slowed down overall degradation. In the second part of this research, the acrylic varnishes Golden Polymer Varnish with UVLS, Lascaux Acrylic Transparent Varnish-UV, Sennelier Matte Lacquer with UV Protection, and Liquitex Soluvar Varnish containing ultraviolet light absorbers or stabilizers were tested as a preventative coating for rubber. Through testing the visual and physical properties of the samples, as well as compound analysis the results of this research suggest that acrylic varnishes do provide protection, each to varying degrees. The results also provided insight into the behavior of rubber and these varnishes with continuing light exposure.

Child Protection Work and Family Support Practice in Five Family Centres

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.

Chronic child abuse: The characteristics and careers of children caught in the child protection system

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.
