Interrogating Mixed-Race: A Crisis of Ambiguity?

In many respects, issues surrounding ‘mixed-race’ identities rupture and dislocate much current thinking within post-race and new ethnicities paradigms. This article seeks to critically engage with what is arguably a marginalized and diverse ‘community’. An evaluation of theories emanating from the UK and USA seeks to challenge hybrid degenerative theories, and more recent attempts at explaining how such identities are negotiated in complex social arenas. What emerges is that some theories are underpinned by static and linear behavioural patterns, which appear oversimplified. Key questions are raised in order to further explore whether ‘mixed-race’ identities are genuinely marginalized and remain ambiguous in a range of physical, social, emotional and ideological contexts. Reflecting upon such issues seeks to prompt questions as to whether there can be a more sophisticated and sensitive understanding of the unique experiences (both positive and negative) of ‘mixed-race’ individuals. By doing so, it is hoped that such a topic becomes more central to considerations of how prejudice and discrimination operate across and within a wide variety of settings.     

The Role of Revenue‐Focused Managerial Performance Measures in Supply Chain Coordination

Many firms employ revenue‐focused managerial performance measures (RF‐MPMs) that cause managers to worry more about revenues than about costs. Although this can seemingly misalign the interests of a manager, we show that the use of such measures can help supply chain partners to overcome hold‐up issues with respect to capacity and promotion investments. We develop a game theoretic model in which two supply chain partners engage in repeated interactions in which the supplier invests in capacity and the buyer invests in demand promotion. Following the realization of demand in each period, the two firms negotiate over the output quantity and wholesale price. The novelty of our model is that we allow the owners of each firm to delegate decision‐making power and negotiating responsibility to a free‐agent manager. We characterize the conditions under which the owners of both firms employ RF‐MPMs in equilibrium and benefit from doing so. For a special case of our model, we show that for the owners of the buyer, an RF‐MPM is equivalent to a price only relational contract, and that it complements a price and quantity relational contract as a mechanism for mitigating hold‐up issues.     

中国特色社会主义理论体系发展阶段之探析

中国特色社会主义理论体系的形成过程中有邓小平理论、"三个代表"重要思想、科学发展观等重大战略思想。要从整体把握上区分"年轮"与阶段;《论十大关系》是开创篇和历史起点、逻辑起点;从《论十大关系》到中共十二大是起始阶段,到十四大是理论基本内容体系化阶段,到十五届五中全会是基本内容体系整体与时俱进的深化阶段,到十七大是理论体系成熟并确立的阶段,十七大后是完善充实阶段,将来是创新发展阶段。

Risk Estimation and Value-of-Information Analysis for Three Proposed Genetic Screening Programs for Chronic Beryllium Disease Prevention

Genetic differences (polymorphisms) among members of a population are thought to influence susceptibility to various environmental exposures. In practice, however, this information is rarely incorporated into quantitative risk assessment and risk management. We describe an analytic framework for predicting the risk reduction and value-of-information (VOI) resulting from specific risk management applications of genetic biomarkers, and we apply the framework to the example of occupational chronic beryllium disease (CBD), an immune-mediated pulmonary granulomatous disease. One described Human Leukocyte Antigen gene variant, HLA-DP beta 1*0201, contains a substitution of glutamate for lysine at position 69 that appears to have high sensitivity (approximately 94%) but low specificity (approximately 70%) with respect to CBD among individuals occupationally exposed to respirable beryllium. The expected postintervention CBD prevalence rates for using the genetic variant (1) as a required job placement screen, (2) as a medical screen for semiannual in place of annual lymphocyte proliferation testing, or (3) as a voluntary job placement screen are 0.08%, 0.8%, and 0.6%, respectively, in a hypothetical cohort with 1% baseline CBD prevalence. VOI analysis is used to examine the reduction in total social cost, calculated as the net value of disease reduction and financial expenditures, expected for proposed CBD intervention programs based on the genetic susceptibility test. For the example cohort, the expected net VOI per beryllium worker for genetically based testing and intervention is $13,000, $1,800, and $5,100, respectively, based on a health valuation of $1.45 million per CBD case avoided. VOI results for alternative CBD evaluations are also presented. Despite large parameter uncertainty, probabilistic analysis predicts generally positive utility for each of the three evaluated programs when avoidance of a CBD case is valued at $1 million or higher. Although the utility of a proposed risk management program may be evaluated solely in terms of risk reduction and financial costs, decisions about genetic testing and program implementation must also consider serious social, legal, and ethical factors.     

Older family-carers' views on the future accommodation needs of relatives who have an intellectual disability

Over the past 20 years, research across the developed world has identified trends towards ageing of the population with learning/intellectual disability. Alongside is the recognition that family-carers are also ageing. Recently, the UK government has sought to identify the future housing needs of dependents with intellectual disability residing with older carers. Consequentially, a city council commissioned this qualitative study involving 28 older carers. The findings indicate a need for information about housing options, a lack of practical support and feelings of marginalisation. The conclusions suggest key roles for social services in providing proactive support and advice to family-carers, and a greater degree of joint working between social services departments and housing agencies. These resonate with similar international studies and provide the opportunity to focus on the perspectives of family-carers. Their experiences are real, and if welfare professionals are to work with people with intellectual disability and their family-carers, acknowledging their views is essential.
