Using public procurement to achieve social outcomes

The use of public procurement to achieve social outcomes is widespread, but detailed information about how it operates is often sketchy and difficult to find. This article is essentially a mapping exercise, describing the history and current use Of government contracting as a tool of social regulation, what the author calls the issue of 'linkage'. The article considers the popularity of linkage in the I 9,h century in Europe and North America, particularly in dealing with issues of labour standards and unemployment. The use of linkage expanded during the 20(th) century, initially to include the provision of employment opportunities to disabled workers. During and after World War 11, the use of linkage became particularly important in the United States in addressing racial equality, in the requirements for non-discrimination in contracts, and in affirmative action and set-asides for minority businesses. Subsequently, the role of procurement spread both in its geographical coverage and in the subject areas of social policy that it was used to promote. The article considers examples of the use of procurement to promote equality on the basis of ethnicity and gender drawn from Malaysia, South Africa, Canada, and the European Community. More recently, procurement has been used as an instrument to promote human rights transnationally, also by international organizations such as the International Labour Organisation. The article includes some reflections on the relationship between 'green' procurement, 'social' procurement, and sustainable development, and recent attempts to develop the concept of 'sustainable procurement.

INTRAPOPULATION VARIATION IN THE DIET OF THE WOOD MOUSE APODEMUS-SYLVATICUS

Variation in the diet of wood mice, Apodemus sylvaticus, was investigated in two contrasting habitats, deciduous and coniferous woodland, over 26 months and in 10 additional sites trapped during winter. Stomach contents were categorized as seed, fruit, green plant, root and animal material. Diet was evaluated using the percentage occurrence of each food type. Age and sex differences in diet occurred infrequently. Seed predominated throughout but was especially prevalent in autumn and winter. There was a peak in the incidence of animal material in the spring and early summer. Animal food was generally more frequent in mice caught in conifer plantations than in deciduous woodland during the longer-term study. Further, mice from the additional coniferous habitats had greater percentage occurrence of animal food than those from the additional deciduous sites. There was a negative, non-linear association between relative population size and diet in these winter samples. This suggests that spatial variation in numbers of A. sylvaticus is dictated by food availability and density is locally food limited.

Interventions to reduce prejudice and enhance inclusion and respect for ethnic differences in early childhood: A systematic review

A systematic review was conducted of studies evaluating the effects of interventions aimed at reducing ethnic prejudice and discrimination in young children. Articles published between 1980 and 2010 and including children of 8 years and under were identified, harvested, and assessed for quality, both for the exposure/program as well as for the evaluation. In total, 32 studies (14 contact and 18 media or instruction) yielded 62 effects on attitudes and 59 effects on peer relations. An overall count of the positive (40%), non-significant (50%), and negative effects (10%) indicate a mixed picture. Overall, more attitude effects (55%) than peer relations effects (25%) were positive, and media/instruction (47%) was more successful than contact (36%). Most of the effects were observed with children from a majority ethnicity: 67% of the attitude effects were positive, and media/instruction and contact were equally effective at delivering these. Few differences were found as a function of the quality of the exposure and evaluation, but differences were found depending on the context of exposure (naturally occurring or experimental manipulation) and research design (random assignment or self-selection). In conclusion, the findings were more mixed than expected, though sufficiently strong studies exist to provide lessons for future research.

The Oxford Handbook of Conflict Management in Organizations

New ways of managing conflict are increasingly important features of work and employment in organizations. In the book the world's leading scholars in the field examine a range of innovative alternative dispute resolution (ADR) practices, drawing on international research and scholarship and covering both case studies of major exemplars and developments in countries in different parts of the global economy. Developments in the management of individual and collective conflict at work are addressed, as are innovations in both unionized and non-union organizations and in the private and public sectors.

New practices for managing conflict in organizations are set in the context of trends in workplace conflict and perspectives on how conflict should be understood and addressed. Part 1 examines the changing context of conflict management by addressing the main frameworks for understanding conflict management, the trend in conflict at work, developments in employment rights, and the influence of HRM on conflict management. Part 2 covers the main approaches to conflict management in organizations, addressing both conventional and alternative approaches to conflict resolution. Conventional grievance handling and third-party processes in conflict resolution are examined as well as the main ADR practices, including conflict management in non-union firms, the role of the organizational ombudsman, mediation, interest-based bargaining, line and supervisory management, and the concept of conflict management systems. Part 3 presents case studies of exemplars and innovators in the field, covering mediation in the US postal service, interest-based bargaining at Kaiser-Permanente, 'med-arb' in the New Zealand Police, and judicial mediation in UK employment tribunals. Part 4 covers international developments in conflict management in Germany, Japan, The United States, Australia, New Zealand, the United Kingdom and China.

This Handbook gives a comprehensive overview of this growing field, which has seen an huge increase in programmes of study in university business and law schools and in executive education programmes.

Restorative Justice and Sex Offending

This essay examines the origins and uses of restorative justice with sexual offending and the contemporary challenges and controversies surrounding this. It charts the range of ad hoc initiatives which have sought to apply a restorative form of intervention with violent or sexual offending from first time and ‘acquaintance’ rape as well as young sexual abusers to high risk sexual offenders in the form of circles of support and accountability. Such schemes are often presented as a counter to the failings of retributive forms of justice and are premised on Braithwaite’s (1989) notion of ‘reintegrative shaming’ that seek to reintegrate offenders into the community. Critics of restorative justice traditionally put forward a number of core objectives when restorative justice is applied to serious forms of offending such as sexual offending. The essay also sets out and seeks to counter these principal challenges and how they may be overcome. For the most part, however, restorative justice has failed to reach its potential as a fully fledged sentencing rationale in being applied as a mainstream response to a wide range of offending including that at the higher end of the spectrum. The essay also seeks to examine barriers to restorative justice within contemporary penal policy and to highlight some of the most controversial applications of the restorative paradigm including those related to clergy sexual abuse. It concludes by offering some thoughts on the future of restorative justice as a mainstream responses to serious forms of offending.

Interspecific comparison of estrogen and testosterone concentrations in three species of amphipods (Gammarus duebeni celticus, G. pseudolimnaeus, and G. pulex)

The presence and biological significance of vertebrate-related steroid sex hormones in aquatic invertebrates are poorly understood. We compared the concentrations of estrogen (17β-estradiol) and testosterone between amplexing male and female freshwater amphipods of three species from two continents: Gammarus duebeni celticusLiljeborg, 1852 and G. pulex(L., 1758) from Europe, and G. pseudolimnaeusBousfield, 1958 from North America. All three species were found to have measureable concentrations of both hormones in whole body lysate samples but the concentrations differed between species, with testosterone differing significantly between species only for male amphipods and estradiol differing significantly between species only for female amphipods. Concentrations of both testosterone and estrogen differed between males and females in two of the three species ( G. duebeni celticusand G. pseudolimnaeus). Females had the highest concentration of both hormones in G. duebeni celticusand the lowest concentration of both hormones in G. pseudolimnaeus. These results contribute to a growing body of evidence that these hormones are endogenously produced and biologically relevant in amphipods. Such evidence is particularly important in light of increasing prevalence of endocrine-disrupting compounds in the environment and the central role played by amphipods in aquatic ecosystems.

Molecular pathways: Estrogen pathway in colorectal cancer.

Worldwide, colorectal cancer has a higher incidence rate in men than in women, suggesting a protective role for sex hormones in the development of the disease. Preclinical data support a role for estrogen and its receptors in the initiation and progression of colorectal cancer and establishes that protective effects of estrogen are exerted through ERβ. Hormone replacement therapy (HRT) in postmenopausal women as well as consumption of soy reduces the incidence of colorectal cancer. In the Women's Health Initiative trial, use of HRT in postmenopausal women reduced the risk of colon cancer by 56% [95% confidence interval (CI), 0.38-0.81; P = 0.003]. A recent meta-analysis showed that in women, consumption of soy reduced the risk of colon cancer by 21% (95% CI, 0.03-0.35; P = 0.026). In this review, using the preclinical data, we translate the findings in the clinical trials and observational studies to define the role of estrogen in the prevention of colorectal cancer. We hypothesize that sometime during the tumorigenesis process ERβ expression in colonocytes is lost and the estrogen ligand, HRT, or soy products, exerts its effects through preventing this loss. Thus, in the adenoma-to-carcinoma continuum, timing of HRT is a significant determinant of the observed benefit from this intervention. We further argue that the protective effects of estrogen are limited to certain molecular subtypes. Successful development of estrogen modulators for prevention of colorectal cancer depends on identification of susceptible colorectal cancer population(s). Thus, research to better understand the estrogen pathway is fundamental for clinical delivery of these agents.

Inbreeding uncovers fundamental differences in the genetic load affecting male and female fertility in a butterfly

Inbreeding depression is most pronounced for traits closely associated with fitness. The traditional explanation is that natural selection eliminates deleterious mutations with additive or dominant effects more effectively than recessive mutations, leading to directional dominance for traits subject to strong directional selection. Here we report the unexpected finding that, in the butterfly Bicyclus anynana, male sterility contributes disproportionately to inbreeding depression for fitness (complete sterility in about half the sons from brother-sister matings), while female fertility is insensitive to inbreeding. The contrast between the sexes for functionally equivalent traits is inconsistent with standard selection arguments, and suggests that trait-specific developmental properties and cryptic selection play crucial roles in shaping genetic architecture. There is evidence that spermatogenesis is less developmentally stable than oogenesis, though the unusually high male fertility load in B. anynana additionally suggests the operation of complex selection maintaining male sterility recessives. Analysis of the precise causes of inbreeding depression will be needed to generate a model that reliably explains variation in directional dominance and reconciles the gap between observed and expected genetic loads carried by populations. This challenging evolutionary puzzle should stimulate work on the occurrence and causes of sex differences in fertility load.

Bereavement outcomes: a quantitative survey identifying risk factors in family carers bereaved through cancer.

Background: Enabling patients to die in their preferred place is important but achieving preferred place of death may increase the informal carer’s risk into bereavement. Aim: to determine risk factors of family carers bereaved through cancer in Northern Ireland. Design: These results form part of a larger QUALYCARE-NI study which used postal questionnaires to capture quantitative data on carer’s bereavement scores using the Texas Revised Inventory of Grief. Setting/participants: Participants were individuals who: registered the death of a person between 1st December 2011 and 31st May 2012; where cancer (defined by ICD10 codes C00-D48) was the primary cause; where the deceased was over 18 years of age and death occurred at home, hospice, nursing home or hospital in Northern Ireland. Participants were approached in confidence by the Demography and Methodology Branch of the Northern Ireland Statistics and Research Agency. Those wishing to decline participation were invited to return the reply slip. Non-responders received a second questionnaire six weeks after initial invitation. Results indicated that risk factors positively influencing bereavement outcomes included patients having no preference for place of death and carers remaining in employment pre or post bereavement. In contrast, patients dying in hospital, carers stopping work, being of lower socio-economic status and close kinship to the deceased negatively impacted on bereavement scores. Family carers should be adequately supported to continue in employment; priority should be given to assessing the financial needs of families from lower socio-economic areas; and bereavement support should focus on close relatives of the deceased.
