A Systems Approach to the Policy‐Level Risk Assessment of Exotic Animal Diseases: Network Model and Application to Classical Swine Fever

Exotic animal diseases (EADs) are characterized by their capacity to spread global distances, causing impacts on animal health and welfare with significant economic consequences. We offer a critique of current import risk analysis approaches employed in the EAD field, focusing on their capacity to assess complex systems at a policy level. To address the shortcomings identified, we propose a novel method providing a systematic analysis of the likelihood of a disease incursion, developed by reference to the multibarrier system employed for the United Kingdom. We apply the network model to a policy‐level risk assessment of classical swine fever (CSF), a notifiable animal disease caused by the CSF virus. In doing so, we document and discuss a sequence of analyses that describe system vulnerabilities and reveal the critical control points (CCPs) for intervention, reducing the likelihood of U.K. pig herds being exposed to the CSF virus.     

Vector autoregressive models with measurement errors for testing Granger causality

This paper develops a method for estimating the parameters of a vector autoregression (VAR) observed in white noise. The estimation method assumes that the noise variance matrix is known and does not require any iterative process. This study provides consistent estimators and the asymptotic distribution of the parameters required for conducting tests of Granger causality. Methods in the existing statistical literature cannot be used for testing Granger causality, since under the null hypothesis the model becomes unidentifiable. Measurement error effects on parameter estimates were evaluated by using computational simulations. The results suggest that the proposed approach produces empirical false positive rates close to the adopted nominal level (even for small samples) and has a satisfactory performance around the null hypothesis. The applicability and usefulness of the proposed approach are illustrated using a functional magnetic resonance imaging dataset.     

Interpretative phenomenological analysis of young people's lived experiences of therapeutic residential care

Concerns of maltreatment and poor outcomes persist in residential care despite numerous government inquiries and recommendations. Young people in residential care continue to be the most vulnerable and marginalized group in the out‐of‐home care population. Young people's voices are also underrepresented in research. Existing studies predominantly focus on service evaluations in which individual voices of young people are overshadowed by adults' perspectives. Other studies examine the perspectives of young people in out‐of‐home care as a homogenous population, limiting understandings of the subjective experiences of young people in residential care. This study focused exclusively on young people's lived experiences in Australian therapeutic residential care, utilizing interpretative phenomenological analysis. The young people in this study revealed experiences of peer victimization, ambiguous loss and uncertainty during transitions. These findings suggest that more work is required in order to provide safe and healing environments and experiences for young people in therapeutic residential care. Each individual voice captured in this study offers valuable insights into how residential care practitioners can strengthen practice to enhance protection, engagement, connection with families and leaving care support.     

He wahine tangi tikapa 1 …: Statutory investigative processes and the grieving of Maori families who have lost a baby to SIDS

Abstract

Among Maori families, the loss of an infant to SIDS is a terrible burden that reverberates through social networks for years after the event. The statutory services that investigate the death have a huge impact on such processes. This qualitative investigation studied the experiences of whanau following a SIDS death by reporting narrative data, gathered from families, police officers, coroners, and pathologists. Thematic analyses revealed multiple domains of high significance—police actions, post‐mortem, and coronial process—to bereaved whanau, and this paper considers their implications for grieving, service provision, and social justice.     

Applications to Social Work Programmes in England: Students as Consumers?

One of the most resounding impacts of the introduction of the new social work degree in England in 2003 has been an increase in the number of applications to social work courses. However, the processes used by applicants to reach decisions about where to study social work are little understood. This article reports data from six preparatory focus groups and four interviews (n = 38), 17 focus group interviews with first year students (n = 112) from nine social work programmes run in six universities, and 2,606 responses to three online surveys administered to first year students, which were collected as part of the national Evaluation of the New Social Work Degree in England funded by the Department of Health. They show that students use a range of sources to find out about social work education, with rising reliance on electronic media as an information resource. Although the majority cites convenience of location as the chief reason for selecting a particular university, academic reputation appears to be growing in importance. Observations from these data are discussed in the context of consumer behaviour in higher education and in social work education at a time when universities are developing marketing strategies to compete for students.     

LATIN AMERICA

Abstract

This article draws on theories of colonial discourse, cultural representation, subjectivity, feminist studies, cultural studies, and historical analysis to examine how the representations of American Indians in 1990s television fiction are constructed, especially in the American television fictions Northern Exposure, Twin Peaks and Paradise. Central to this analysis is the discussion of colonial discourse and representations of American Indians as Other on popular American television and, more generally, in mainstream American discourse. This examination is set in the context of the issues surrounding the treatment of Indian people in mainstream history, in film, and in contemporary television fiction. It is the authors' position that in the easy acceptance of a stereotyped cultural construction, mainstream America has come to little knowledge or understanding of American Indian nations, their contemporary concerns, or their discrete identities. For the mass market, their contemporary concerns, or their discrete identities. For the mass market, the Indian is either the Vanishing Race of Edward Curtis's photographs or the savage of the captivity narratives, and the process by which that imaginary functions to contain American Indian identity continues in our most popular narrative today: television fiction.     

The Relationship between a History of Childhood Sexual Abuse and Gender Role Attitudes

This study explored the relationship between childhood sexual abuse and gender role attitudes. Female university students rated themselves and their parents on gender role attitudes and history of childhood sexual abuse. Traditional participant gender role attitude and social isolation were associated with reporting being sexually abused as a child and may thus be risk factors for, or the result of a history of, CSA in women. Traditional participant gender role attitude and low income were associated with victim distress and therefore may be detrimental to coping with a history of childhood sexual abuse. Although replication of these results is needed, discovery of attitudinal and demographic variables associated with CSA may be important in the prevention and treatment of CSA.     

Reduced inhibitory control predicts persistence in laboratory slot machine gambling

Impairments in inhibitory control characterize a range of addictive behaviours including gambling disorder. This study investigated the relationship between a neuropsychological measure of inhibitory control and behaviour on a simulated slot machine that included a measure of gambling persistence, in a non-clinical sample of regular gamblers. Regular gamblers (n = 75) performed a laboratory slot machine task for 30 trials where they could win real money, followed by a persistence phase under extinction (i.e. without wins). Participants also completed a stop-signal task, along with measures of gambling-related cognitions, social desirability, and symptoms of disordered gambling. In hierarchical regression models, reduced inhibitory control was found to predict greater persistence and a higher subjective desire to play again after both wins and near-misses (i.e. unsuccessful outcomes close to the jackpot). These data illustrate the impact of low inhibitory control on relevant behavioural tendencies in a group of regular gamblers. Our results help elucidate a cognitive process that may contribute to problem gambling, with implications for screening and treatment.
