‘Broad consensus across the divide’: rhetorical constructions of climate change in mainstream news media

The links between science and policy are navigated prominently in the media. The internet provides a forum for discussion of climate change, allowing lay people to enter the debate. In this paper, rhetorical analysis was used to analyse online news articles and comments from the public following two major climate-related decisions in New Zealand. This analysis demonstrates how arguments regarding climate change are built and defended. Identifying strategies invoked by those that occupy a majority or minority position within public discourse on climate change reveals how such arguments take on rhetorical force, providing the basis for establishing claims and counter-arguments. Understanding the rhetorical constructions of such positions can reveal why particular arguments might gain power, opening the way for a more knowledgeable and informed positioning of individuals, organisations, and scientific knowledge to emerge in public debates on climate change.     

A Literature Review and Development of a Theoretical Model for Understanding Commitment Experienced by Volunteers Over the Life of a Project

Employee commitment to an organisation is accepted as an important concept in organisation psychology. Yet commitment to a project on which an employee might be working is largely unknown. Additional complications arise when the project makes use of volunteers who donate their time for reasons other than pecuniary reward. The relationships between volunteers, organisations and projects represent a gap in the field of organisational commitment knowledge. This paper identifies from literature the values that inform and influence volunteer commitment levels. Known antecedents of commitment are developed to present a model which encapsulates the variables that should be recognised as influencing volunteer commitment levels within a project context. The paper proposes a conceptual model of volunteer commitment to a project using three categories of commitment: emotional, purposeful and contextual, and concludes that the next phase of the study will test this model and develop a tool that will enable the measurement of volunteer commitment in a project context.     

Managing physical and mental health conditions: Consumer perspectives on integrated care

Despite the growing trend of integrating primary care and mental health services, little research has documented how consumers with severe mental illnesses (SMI) manage comorbid conditions or view integrated services. We sought to better understand how consumers perceive and manage both mental and physical health conditions and their views of integrated services. We conducted semi-structured interviews with consumers receiving primary care services integrated in a community mental health setting. Consumers described a range of strategies to deal with physical health conditions and generally viewed mental and physical health conditions as impacting one another. Consumers viewed integration of primary care and mental health services favorably, specifically its convenience, friendliness, and knowledge of providers, and collaboration between providers. Although integration was viewed positively, consumers with SMI may need a myriad of strategies and supports to both initiate and sustain lifestyle changes that address common physical health problems.     

Neighborhood Diversity, Metropolitan Constraints, and Household Migration

Focusing on micro-level processes of residential segregation, this analysis combines data from the Panel Study of Income Dynamics with contextual information from three censuses and several other sources to examine patterns of residential mobility between neighborhoods populated by different combinations of racial and ethnic groups. We find that despite the emergence of multiethnic neighborhoods, stratified mobility dynamics continue to dominate, with relatively few black or white households moving into neighborhoods that could be considered multiethnic. However, we also find that the tendency for white and black households to move between neighborhoods dominated by their own group varies significantly across metropolitan areas. Black and white households' mobility into more integrated neighborhoods is shaped substantially by demographic, economic, political, and spatial features of the broader metropolitan area. Metropolitan-area racial composition, the stock of new housing, residential separation of black and white households, poverty rates, and functional specialization emerge as particularly important predictors. These macro-level effects reflect opportunities for intergroup residential contact as well as structural forces that maintain residential segregation.     

RADIOISOTOPE PRODUCTION SCHEDULING IN A NUCLEAR REACTOR

A multiperiod mixed integer programming model has been developed for the production scheduling of several grades of a radioisotope in a nuclear reactor. Of special interest is the model's capability to evaluate possible future product “short falls” due to the acceptance of an unforecasted demand sales opportunity. The model is essential to decisions concerning reactor loading after an extended shutdown of several periods for modifications, maintenance, and upgrading.     

Hygiene and Biosecurity: The Language and Politics of Risk in an Era of Emerging Infectious Diseases

Infectious diseases, such as methicillin-resistant Staphylococcus aureus and avian influenza, have recently been high on the agenda of policy makers and the public. Although hygiene and biosecurity are preferred options for disease management, policy makers have become increasingly aware of the critical role that communication assumes in protecting people during outbreaks and epidemics. This article makes the case for a language-based approach to understanding the public perception of disease. Health language research carried out by the authors, based on metaphor analysis and corpus linguistics, has shown that concepts of journeys, pathways, thresholds, boundaries and barriers have emerged as principal framing devices used by stakeholders to advocate a hygiene based risk and disease management. These framings provide a common ground for debate, but lead to quite different perceptions and practices. This in turn might be a barrier to global disease management in a modern world.     

Internalizing Symptoms in Adolescents: Gender Differences in Vulnerability to Parental Distress and Discord

This longitudinal study investigated gender differences in the relation between (1) internalizing symptoms of depression and anxiety reported by adolescents, and (2) emotional distress and marital discord reported by their mothers. Structural equation modeling was used to track the relationship between these variables in a community sample of 116 males and 101 females and their parents across three data intervals roughly corresponding to early adolescence (M = 11,4), mid‐adolescence (M = 13,7), and late adolescence/early adulthood (M = 19,2). For early adolescents, there were no gender differences in the relation between internalizing symptoms and parental distress and discord. Gender differences did emerge, however, by midadolescence, at which time parental disturbances were significantly associated with internalizing symptoms in adolescent females but not adolescent males. The emergence of this risk factor during this developmental phase may help account for frequent findings that place adolescent females at higher risk for anxiety and depression than adolescent males.     

NEIGHBORHOOD POVERTY AND NONMARITAL FERTILITY: SPATIAL AND TEMPORAL DIMENSIONS

Data from 4,855 respondents to the Panel Study of Income Dynamics were used to examine spatial and temporal dimensions of the effect of neighborhood poverty on teenage premarital childbearing. Although high poverty in the immediate neighborhood increased the risk of becoming an unmarried parent, high poverty in surrounding neighborhoods reduced this risk. The effect of local neighborhood poverty was especially pronounced when surrounding neighborhoods were economically advantaged. Measuring exposure to neighborhood poverty over the childhood life course yielded stronger effects than measuring exposure at a single age. Neither racial differences in the level of poverty in proximate neighborhoods nor racial differences in neighborhood poverty over the childhood life course explained the racial difference in nonmarital fertility.     

Counterterrorism resource allocation during a pandemic: The effects of dynamic target valuations when facing a strategic terrorist

The outbreak of pandemics such as COVID-19 can result in cascading effects for global systemic risk. To combat an ongoing pandemic, governmental resources are largely allocated toward supporting the health of the public and economy. This shift in attention can lead to security vulnerabilities which are exploited by terrorists. In view of this, counterterrorism during a pandemic is of critical interest to the safety and well-being of the global society. Most notably, the population flows among potential targets are likely to change in conjunction with the trend of the health crisis, which leads to fluctuations in target valuations. In this situation, a new challenge for the defender is to optimally allocate his/her resources among targets that have changing valuations, where his/her intention is to minimize the expected losses from potential terrorist attacks. In order to deal with this challenge, in this paper, we first develop a defender–attacker game in sequential form, where the target valuations can change as a result of the pandemic. Then we analyze the effects of a pandemic on counterterrorism resource allocation from the perspective of dynamic target valuations. Finally, we provide some examples to display the theoretical results, and present a case study to illustrate the usability of our proposed model during a pandemic.     

SPATIAL AND TEMPORAL DIMENSIONS OF NEIGHBORHOOD EFFECTS ON HIGH SCHOOL GRADUATION

Research into the effects of neighborhood characteristics on children’s behavior has burgeoned in recent years, but these studies have generally adopted a limited conceptualization of the spatial and temporal dimensions of neighborhood effects. We use longitudinal data from the Panel Study of Income Dynamics and techniques of spatial data analysis to examine how both the socioeconomic characteristics of extralocal neighborhoods—neighborhoods surrounding the immediate neighborhood of residence—and the duration of exposure to disadvantaged neighborhoods throughout the childhood life course influence the likelihood of graduating from high school. Among blacks and whites, socioeconomic advantage in the immediate neighborhood increases the likelihood of completing high school, but among whites higher levels of socioeconomic advantage in extralocal neighborhoods decrease high school graduation rates. Extralocal neighborhood advantage suppresses the influence of advantage in the immediate neighborhood so that controlling for extralocal conditions provides stronger support for the neighborhood effects hypothesis than has previously been observed. Exposure to advantaged neighborhoods over the childhood life course exerts a stronger effect than point-in-time measures on high school graduation, and racial differences in exposure to advantaged neighbors over the childhood life course help to suppress a net black advantage in the likelihood of completing high school.
