Detection of multiple undocumented change-points using adaptive Lasso

The problem of detecting multiple undocumented change-points in a historical temperature sequence with simple linear trend is formulated by a linear model. We apply adaptive least absolute shrinkage and selection operator (Lasso) to estimate the number and locations of change-points. Model selection criteria are used to choose the Lasso smoothing parameter. As adaptive Lasso may overestimate the number of change-points, we perform post-selection on change-points detected by adaptive Lasso using multivariate t simultaneous confidence intervals. Our method is demonstrated on the annual temperature data (year: 1902–2000) from Tuscaloosa, Alabama.     

Piece rates and workplace injury: Does survey evidence support Adam Smith?

While piece rates are routinely associated with higher productivity and wages, they can also generate unanticipated effects. Using cross-country European data, we provide among the first general survey evidence of a strong link between piece rates and workplace injury. Despite controls for workplace hazards, job characteristics and worker effort, piece rates workers suffer a 5 percentage point greater likelihood of injury. This remains despite attempts to control for endogeneity and heterogeneity. As piece rate wage premium estimates rarely control for injury likelihood, this raises the specter that part of that premium reflects a compensating wage differential for risk of injury.     

Testing Multiple Forecasters

We consider a cross‐calibration test of predictions by multiple potential experts in a stochastic environment. This test checks whether each expert is calibrated conditional on the predictions made by other experts. We show that this test is good in the sense that a true expert—one informed of the true distribution of the process—is guaranteed to pass the test no matter what the other potential experts do, and false experts will fail the test on all but a small (category I) set of true distributions. Furthermore, even when there is no true expert present, a test similar to cross‐calibration cannot be simultaneously manipulated by multiple false experts, but at the cost of failing some true experts.     

Eros,eroticism and the pedagogical process

This essay examines the role of authenticity as it appears as a factor in Irish cultural production. Taking examples from Yeats's folklore collections, tourist marketing and beer advertisements, it suggests, using the writings of Adorno, Baudrillard and Jacob Golomb, that the trope of ‘authenticity’ persists, in variant forms, as a marker of how Irish material and textual culture ‘promotes’ itself in a post-colonial context.     

Professional Socialization and Social Work Values: Who Are We Teaching?

Despite the centrality of values to professional socialization, the social work literature lacks an extensive exploration of the readiness of students to be socialized into the profession and taught the theoretical framework and skills for ethical decision making. This study explored the relationship between age, academic class standing, and identity development. Results indicated that the Identity Achievement status occurs later than traditional university years and correlates with age but not with academic class standing. Important implications for teaching social work values, ethical decision making, and the significance of a liberal arts foundation are discussed.     

LESSONS FOR RESEARCHERS AND FUNDING AGENCIES FROM HURRICANE KATRINA: A RESEARCH NOTE FROM MISSISSIPPI

We surveyed National Science Foundation (NSF)-funded research in Mississippi to determine the economic extent of research damage and delays due to Hurricane Katrina. While several facilities were physically damaged, we found that the largest effects were time delays and missed opportunities. While psychological factors were not part of the original economic impact study, it became clear that they played an important role. Specifically, the Principal Investigator's (PI's) attitude of “just another delay” was one cultural barrier to fully accounting for the cost of these research delays. We concluded that Principal Investigators, with the assistance of funding agencies, should be better trained to measure time and opportunity costs associated with their research, so future disaster recovery efforts can more fully address those needs.     

Preparation for practice: embedding the development of professional identity within social work curriculum

Newly qualified social workers often enter challenging interdisciplinary settings where they need to be able to clearly articulate a distinctive professional identity. To prepare for these realities, this paper discusses how the development of professional identity has become increasingly central to qualifying social work curriculum at an Australian university. Preparation for social work practice has long been the focus of research in a number of countries, with a significant emphasis on knowledge and skill acquisition, rather than on the development of an overarching professional identity that is also underpinned by shared values and sense of professional purpose and expectations. Against this backdrop, the paper describes initial changes that have been made within core social work courses to progressively embed the development of professional identity more consciously across their studies, to be better prepared for contemporary challenges in the workplace. It is concluded that further changes are needed to fully transform the curriculum, and that the impacts of these changes be systematically evaluated in relation to preparedness for practice.     

Feminism and women's film criticism in post-war Britain, 1945–1959

Feminist film criticism is widely thought to have started in the late 1960s and early 1970s when the “Images of Woman” debate associated with critics such as Marjorie Rosen provided the foundation for later developments in feminist film theory. Antonia Lant has recently claimed the immediate post-1950 period to be a barren time for female-authored publications on film and cinema. This article argues that, contrary to received wisdom, the post-war period (1945–1959) in Britain was a time when women's film criticism flourished, with writers such as Dilys Powell, C.A. Lejeune, Catherine de la Roche and E. Arnot Robertson enjoying high-profile careers. Moving beyond a simple recovery of women's “hidden histories,” this article highlights the points of connection between the post-war period and later film criticism informed by second wave feminism. Through a case study of de la Roche and Robertson this article explores how women critics in this period were similarly preoccupied with screen representations of women and women's roles within the film industry, anticipating the later concerns of Rosen and others. I argue that a cross-media focus is a productive method for generating insights into women's critical agency at this time, and conclude that women's film criticism demonstrates something of the wider shifts taking place in gender relations in British society.     

Case Management with Displaced Survivors of Hurricane Katrina

Abstract

Case management is a staple of post-disaster recovery, but there is limited research on this topic. Utilizing in-depth interviews, observations, and document analysis, based on 78 interviews and attendance at approximately 50 public meetings, this longitudinal case study examined case management with displaced hurricane Katrina survivors in one host community between December 2005 and December 2006. Case managers identified, assessed, planned, linked, monitored, and advocated for survivors. They described engaging survivors and understanding their backgrounds and experiences as challenging. Lack of jobs, transportation, and affordable housing coupled with survivors' trauma and preexisting needs presented barriers to long-term recovery. Despite these difficulties, case managers felt positively about their efforts and identified coordination as a critical element for successful human/social services responses to natural disasters.     

Exploring how workplace and social policies relate to caregivers’ financial strain

Informal caregiving is a critical component of the US long-term care system, but can have significant negative impacts on caregiver employment, finances, and well-being. An online survey of Colorado caregivers was piloted in 2016–17 to explore whether workplace and social policies such as access to paid family leave and public health insurance can buffer the negative financial impacts of caregiving and help caregivers to remain in the workforce. Using standardized measures, the survey assessed caregivers’ employment and financial status, well-being (physical and mental health, caregiver strain, benefits of caregiving), access to workplace supports, and covariates (e.g., caregiver demographics, health, social support, and service utilization). Ninety-five caregivers, recruited through community agency partners, completed the survey. Respondents were predominately female (89%), middle-aged (M = 57), non-Hispanic White (64%) or Latino/a (22%), and caring for a parent (40%) or spouse (30%) for over one year. Half (51%) reported working full- or part-time jobs, while 16.4% had stopped working because of caregiving. In multivariate regression modeling, predictors of financial strain included the care recipients’ financial strain and the caregiver’s reduction or ceasing of work. Medicare may be protective to minimize caregivers’ need to reduce or cease work. Implications for caregivers’ ability to stay engaged in the workforce and prepare for their own retirement are explored.
