Relationships matter: The problems and prospects for social workers' relationships with young children in care

One of the key lessons learnt in the UK from the Laming Inquiry into the death of Victoria Climbié was the importance of social workers developing consistent and long-term relationships with young children in whose lives they are involved. This issue is now informing policy developments, including the proposed Social Work Practices which, based on a similar model to General Practitioner practices, aim to provide a lead professional to act as a parental figure and an advocate for every child in care. This paper begins by confirming the importance of developing relationships between social workers and young children, but questions the ability of the new policy developments to facilitate these. Drawing upon data from research involving interviews with social workers, the paper outlines the factors which hinder social workers' relationships with young children and argues that while the new proposals address some of the more surface structural and organizational factors, they do not address the deeper factors regarding attitudes, values and emotional competence which are crucial if social workers are to successfully build relationships with young children in care.

Assessment framework for construction supply chain relationships: Development and evaluation

The change of supply chain relationships from the traditional adversarial to the collaborative has been increasing in the UK construction industry. To reflect this change, some attempts have been made to establish models for measuring and improving supply chain relationships in construction. However, there are obvious deficiencies in these existing models. This highlights the need for a systematic model for the assessment of construction supply chain relationships. Based on a review of the literature and an expert group discussion, an assessment framework is developed in this paper, which consists of assessment criteria, relationship levels, detailed descriptions, assessment classes and assessment procedures. The proposed framework is evaluated through expert interviews and case studies. This framework provides a roadmap for the improvement of supply chain relationships. It can help construction organisations to position their current relationship and identify key areas for relationship improvement in the future.

Structure-Property Relationships in Biaxially Deformed Polypropylene Nanocomposites

Semi-solid forming processes such as thermoforming and injection blow moulding are used to make much of today’s packaging. As for most packaging there is a drive to reduce product weight and improve properties such as barrier performance. Polymer nanocomposites offer the possibility of increased modulus
(and hence potential product light weighting) as well as improved barrier properties and are the subject of much research attention. In this particular study, polypropylene–clay nanocomposite sheets produced via biaxial deformation are investigated and the structure of the nanocomposites is quantitatively determined in order to gain a better understanding of the influence of the composite structure on mechanical properties. Compression moulded sheets of polypropylene and polypropylene/Cloisite 15A nanocomposite (5 wt.%) were biaxially stretched to different stretching ratios, and then the structure of
the nanocomposite was examined using XRD and TEM techniques. Different stretching ratios produced different degrees of exfoliation and orientation of the clay tactoids. The sheet properties were then investigated using DSC, DMTA, and tensile tests .It was found that regardless of the degree of exfoliation or
orientation, the addition of clay has no effect on percentage crystallinity or melting temperature, but it has an effect on the crystallization temperature and on the crystal size distribution. DMTA and tensile tests show that both the degree of exfoliation and the degree of orientation positively correlate with the dynamic mechanical properties and the tensile properties of the sheet.
