Northern Ireland is still a country riven by segregation, caught between peace and reconciliation. Extensive survey research shows that intergroup contact has a key role to play in achieving reconciliation, whether through generic contact, cross-group friends (most effective) or indirect forms of contact. Segregation is most profound in education, but we show the benefits of contact in all mixed schools. A recent evaluation of a new Shared Education Programme (SEP), that provides children with the opportunity to study with and meet pupils from the other community, reveals reliable effects via promoting contact. The Northern Ireland Assembly’s support for SEP is based on sound psychological principles and robust research evidence.

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the Western world. It is becoming increasingly clear that CRC is a diverse disease, as exemplified by the identification of subgroups of CRC tumours that are driven by distinct biology. Recently, a number of studies have begun to define panels of diagnostically relevant markers to align patients into individual subgroups in an attempt to give information on prognosis and treatment response. We examined the immunohistochemical expression profile of 18 markers, each representing a putative role in cancer development, in 493 primary colorectal carcinomas using tissue microarrays. Through unsupervised clustering in stage II cancers, we identified two cluster groups that are broadly defined by inflammatory or immune-related factors (CD3, CD8, COX-2 and FOXP3) and stem-like factors (CD44, LGR5, SOX2, OCT4). The expression of the stem-like group markers was associated with a significantly worse prognosis compared to cases with lower expression. In addition, patients classified in the stem-like subgroup displayed a trend towards a benefit from adjuvant treatment. The biologically relevant and poor prognostic stem-like group could also be identified in early stage I cancers, suggesting a potential opportunity for the identification of aggressive tumors at a very early stage of the disease.

This paper considers the use of value capture (VC) as a means of financing public-private partnerships (PPPs) in the United Kingdom (UK). Although some VC techniques are used in the UK, they are employed more widely in the United States of America. After considering the traditional approach to financing UK PPPs, this paper describes the main VC finance instruments. The findings of a series of case studies are then presented and conclusions drawn. While VC financing may prove unpopular with those bearing the cost of infrastructure improvements, it is recommended that such instruments are considered by UK policy makers.

Much interest now focuses on the use of the contingent valuation method (CVM) to assess non-use value of environmental goods. The paper reviews recent literature and highlights particular problems of information provision and respondent knowledge, comprehension and cognition. These must be dealt with by economists in designing CVM surveys for eliciting non-use values. Cognitive questionnaire design methods are presented which invoke concepts from psychology and tools from cognitive survey design (focus groups and verbal reports) to reduce a complex environmnetal good into a meaningful commodity that can be valued by respondents in a contingent market. This process is illustrated with examples from the authors' own research valuing alternative afforestation programmes. -Authors
