Sensitive topics in social research involving children

While there is broad consensus that involving children in research is critically important for understanding their lives, there is considerable caution around their participation in social research on ‘sensitive’ issues. Such caution is further amplified by a lack of agreement about what constitutes a ‘sensitive topic’. This article draws on data from interviews with a range of Australian stakeholders, including children, parents, researchers, ethics committee members, government and non-government organisation representatives, and other decision-makers, specifically related to the question of ‘what is a sensitive topic?’. While participants identified a range of sensitive topics, findings point to sensitivities being closely linked with the contexts of children’s lives and experiences. This requires researchers to approach research in ways that reflect more nuanced understandings of these sensitivities, help address potential concerns and facilitate the development of research relationships that promote ethical conduct of research with children.     

Telecommunication relay services as a tool for deaf political participation and citizenship

It has long been recognised that deaf people experience barriers to political participation and that notions of citizenship do not take into account the needs of deaf sign language users. In light of an effort at the European level to increase the potential for deaf sign language users to participate in political processes through technology, this paper provides results from a survey study of deaf sign language users across Europe as to their preferences in using Telecommunications Relay Services (TRS), whether they would like to see the establishment of a pan-European multilingual TRS and if they would make use of such a service for the purposes of political participation. Responses from 74 deaf people across 14 European member states confirm that deaf people want to see such a service, and would be willing to use it in order to make contact with European institutions. Therefore, the establishment of such a service has the potential to contribute to improved access to, and increased willingness to engage in, democracy through telecommunications and thus enhance the citizenship status of deaf Europeans, and therefore enhance their political participation and access to information and communication in society.     

Canadian Fossil Capitalism,Corporate Strategy,and Post‐Carbon Futures

This study investigates the relationship between the carbon extractive sector in Canada and renewable energy development. Specifically, it examines the strategies employed by Canadian carbon‐capital firms to shape and control alternative energy and considers if we are witnessing signs of “transition capture” as some oil, gas, and coal firms invest in a gradual shift toward “climate capitalism.” I investigate first, investments by large Canada‐based fossil fuel companies in renewable energy and second, interlocking directorate relations between the fossil fuel sector and the renewables industry. Findings suggest the possibility of a long‐term strategic orientation toward a climate capitalist model of development by some carbon‐capital firms; however, this alignment remains highly tentative, with evidence pointing to an industry that is largely without plans for energy transition.     

The Child Support Enforcement Amendments of 1984 and Educational Attainment of Young Adults in the United States

ABSTRACT: We compare changes in the effect of child support payments on the educational attainment of children age 16 to 19 before and after passage of the Child Support Enforcement Amendments of 1984, which strengthened enforcement of child support obligations in the United States. Using 1979, 1984, and 1988 Current Population Survey data, we hypothesize and find a decline in the positive effect of child support between 1984 and 1988 that exceeds any earlier decline. Instrumental variables estimates provide additional evidence consistent with the idea that child support serves as an indicator of unobservable characteristics of noncustodial fathers who pay support.     

THE OPTIMAL TEST FOR SELECTING THE GREATER OF TWO BINOMIAL PROBABILITIES

The efficiency of a sequential test is related to the “importance” of the trials within the test. This relationship is used to find the optimal test for selecting the greater of two binomial probabilities, p_α and p_b, namely, the stopping rule is “gambler's ruin” and the optimal discipline when p_α+p_b≤ 1 (≥ 1) is play-the-winner (loser), i.e. an α-trial which results in a success is followed by an α-trial (b-trial) whereas an α-trial which results in a failure is followed by α b-trid (α-trial) and correspondingly for b-trials.     

Locality and community: coming to terms with place

The paper seeks to examine how social science has attempted to combine the uniqueness of place with general social processes. Two concepts which have traditionally been used to this end are examined; these are ‘locality’ and ‘community’. It is argued that although community has fallen out of favour, problems associated with the use of ‘locality’ could lead to a revival in the use of the former concept. Case study material from rural Wales is presented to show how the two approaches might usefully be combined.     

A Probabilistic Arsenic Exposure Assessment for Children Who Contact CCA-Treated Playsets and Decks, Part 1: Model Methodology, Variability Results, and Model Evaluation

Concerns have been raised regarding the safety of young children who may contact arsenic residues while playing on and around chromated copper arsenate (CCA)-treated wood playsets and decks. Although CCA registrants voluntarily canceled the production of treated wood for residential use in 2003, the potential for exposure from existing structures and surrounding soil still poses concerns. The EPA's Office of Research and Development developed and applied the probabilistic Stochastic Human Exposure and Dose Simulation model for wood preservatives (SHEDS-Wood) to estimate children's absorbed dose of arsenic from CCA. Skin contact with, and nondietary ingestion of, arsenic in soil and wood residues were considered for the population of children in the United States who frequently contact CCA-treated wood playsets and decks. Model analyses were conducted to assess the range in population estimates and the impact of potential mitigation strategies such as the use of sealants and hand washing after play events. The results show predicted central values for lifetime annual average daily dose values for arsenic ranging from 10(-6) to 10(-5) mg/kg/day, with predicted 95th percentiles on the order of 10(-5) mg/kg/day. There were several orders of magnitude between lower and upper percentiles. Residue ingestion via hand-to-mouth contact was determined to be the most significant exposure route for most scenarios. Results of several alternative scenarios were similar to baseline results, except for the scenario with greatly reduced residue concentrations through hypothetical wood sealant applications; in this scenario, exposures were lower, and the soil ingestion route dominated. SHEDS-Wood estimates are typically consistent with, or within the range of, other CCA exposure models.     

When T cells get old

Why is vaccination against infectious diseases less effective in older patients than in younger ones? Why do the elderly suffer from more frequent and severe infectious episodes than the young? The answer to both these questions is immunosenescence--the poorly defined changes that occur in the immune system as a result of the disrupted performance of multiple components of immunity. Presentations from a recent workshop, which are summarized here, examined these questions and provided some insights from the perspective of improving vaccination strategies among the elderly.
