Victor Branford and the building of British sociology

Victor Branford was a central figure in the institutional development of British sociology in the first thirty years of the twentieth century. He is, however, a neglected figure and little is known about his life and his work in sociology. This article presents a biographical account of Victor Branford and outlines his sociological ideas. Particular attention is given to the part played by Branford and his second wife, Sybella Gurney, in the establishment of the Sociological Society and The Sociological Review. Writing between 1903 and 1930, he set out a distinctive view of the nature of sociology and an account of modernity, which he saw as underpinning a conception of a third way in politics that goes beyond capitalism and socialism. He tied this view, set out in the years after the First World War, to a conception of the public role of sociology in which the sociologist was to be a leading element in the building of social citizenship through social reconstruction.     

Risk-Based Analysis of the Danish Pork Salmonella Program: Past and Future

The Danish pork Salmonella control program was initiated in 1993 in response to a prominent pork-related outbreak in Copenhagen. It involved improved efforts at slaughter hygiene (postharvest) and on-farm (preharvest) surveillance and control. After 10 years, 95 million Euros, significant reductions in seropositive herds, Salmonella positive carcasses, and pork-attributable human cases (PAHC), questions have arisen about how best to continue this program. The objective of this study was to provide some analysis and information to address these questions. The methods used include a computer simulation model constructed of a series of Excel workbooks, one for each simulated year and scenario ( http://www.ifss.iastate/DanSalmRisk ). Each workbook has three modules representing the key processes affecting risk: seropositive pigs leaving the farm (Production), carcass contamination after slaughter (Slaughter), and PAHC of Salmonella (Attribution). Parameter estimates are derived from an extensive farm-to-fork database collected by industry and government and managed by the Danish Zoonosis Centre ( http://www.food.dtu.dk ). Retrospective (1994–2003) and prospective (2004–2013) simulations were evaluated. The retrospective simulations showed that, except for the first few years (1994–1998), the on-farm program had minimal impact in reducing the number of positive carcasses and PAHC. Most of the reductions in PAHC up to 2003 were, according to this analysis, due to various improvements in abattoir processes. Prospective simulations showed that minimal reductions in human health risk (PAHC) could be achieved with on-farm programs alone. Carcass decontamination was shown as the most effective means of reducing human risk, reducing PAHC to about 10% of the simulated 2004 level.     

The Pervasive and Persistent Influence of Caste on Child Mortality in India

This study examines the effect of caste on child mortality and maternal health care utilization in rural India using data from the National Family Health Survey (NFHS-2) carried out during 1998–1999. Results from multilevel discrete-time hazard models indicate that, net of individual-level and community-level controls, children belonging to low castes have higher risks of death and women belonging to low castes have lower rates of antenatal and delivery care utilization than children and women belonging to upper castes. At the same time, the controls account for most of the differences within the low castes. Further analysis shows that the mortality disadvantage of low castes is more pronounced in poorer districts. These results highlight the need to target low caste members in the provision of maternal and child health services.     

Venues and Filters in Managed Migration Policy: The Case of the United Kingdom

The United Kingdom, like many developed world economies, has witnessed unprecedented immigration since the early 1990s. Also in line with other developed world economies, the United Kingdom has adopted a “managed migration” policy paradigm. The paper argues that the operation of this paradigm is best understood with reference to two key concepts: migration policy “venues” and migration policy “filters.” In terms of the former, the paper argues that managed migration policy is associated with outward, upward, and downward rescaling and commensurate venue growth and diversification. In terms of the latter, the paper argues that six policy filters (legal, geographical, credential, transfer‐based, monetary, and humanitarian) are commonly used to determine legitimate forms of migration but that one (the geographical filter) has been particularly prominent within the United Kingdom's managed migration policy paradigm.     

Father's involvement in the lives of children in foster care

Limited understandings exist about non‐resident fathers' views of their involvement with their children in foster care placements. Guided by the ecological systems framework, the purpose of this exploratory study was to gain insights into fathers' perceptions of their involvement with a child in foster care. Data were collected from demographic questionnaires and two focus groups with 17 men. Fathers expressed how kinship compared with non‐kinship placements affected their involvement. Fathers were also in agreement that their financial hardships were a significant factor affecting their involvement. Several fathers also reported how they experienced discrimination in the child welfare system as men. Surprisingly, uncommon to findings from other studies, few men viewed the child's mother as being a barrier to their involvement. The findings provide insights into factors requiring attention to help non‐residential fathers become involved with their children.     

Impact of urban structure on avian diversity along the Truckee River, USA

Urban riparian habitats are potentially important resources for native birds in arid ecosystems. Most studies have assessed the value of urban riparian habitat in terms of vegetation and natural resources; however, the surrounding land use and infrastructure may determine the viability of urban habitat. We studied the impact of urban structure, the combination of land use, infrastructure and vegetation variables that work together to shape the urban environment, on avian riparian habitat in the Truckee Meadows, Nevada, USA. Land use and infrastructure explained avian species richness and abundance better than local vegetation alone, but community resemblance was more strongly correlated to vegetation. Avian species guilds responded differentially to surrounding land use, suggesting there may be a functional difference between land use types. The best models for bird diversity used urban structure (both land use and vegetation) to describe potential habitat. Urban structure describes urban habitat in ways that vegetation variables alone cannot. Studies that ignore land use and infrastructure and other socioeconomic variables are likely missing key functional differences within urban ecosystems, and may miss the potential for compatible development that encourages both biodiversity and urban growth.     

Use of Quality-Adjusted Life Year Weights with Dose-Response Models for Public Health Decisions: A Case Study of the Risks and Benefits of Fish Consumption

Risks associated with toxicants in food are often controlled by exposure reduction. When exposure recommendations are developed for foods with both harmful and beneficial qualities, however, they must balance the associated risks and benefits to maximize public health. Although quantitative methods are commonly used to evaluate health risks, such methods have not been generally applied to evaluating the health benefits associated with environmental exposures. A quantitative method for risk-benefit analysis is presented that allows for consideration of diverse health endpoints that differ in their impact (i.e., duration and severity) using dose-response modeling weighted by quality-adjusted life years saved. To demonstrate the usefulness of this method, the risks and benefits of fish consumption are evaluated using a single health risk and health benefit endpoint. Benefits are defined as the decrease in myocardial infarction mortality resulting from fish consumption, and risks are defined as the increase in neurodevelopmental delay (i.e., talking) resulting from prenatal methylmercury exposure. Fish consumption rates are based on information from Washington State. Using the proposed framework, the net health impact of eating fish is estimated in either a whole population or a population consisting of women of childbearing age and their children. It is demonstrated that across a range of fish methylmercury concentrations (0-1 ppm) and intake levels (0-25 g/day), individuals would have to weight the neurodevelopmental effects 6 times more (in the whole population) or 250 times less (among women of child-bearing age and their children) than the myocardial infarction benefits in order to be ambivalent about whether or not to consume fish. These methods can be generalized to evaluate the merits of other public health and risk management programs that involve trade-offs between risks and benefits.     

Kernel density estimation with binned data

Continuous data are often measured or used in binned or rounded form. In this paper we follow up on Hall's work analyzing the effect of using equally-spaced binned data in a kernel density estimator. It is shown that a surprisingly large amount of binning does not adversely affect the integrated mean squared error of a kernel estimate.
