Streaming Film: How to Serve Our Users

Streaming video is an integral part of the curriculum for many academic courses. While faculty may have used DVDs in the classroom, the increase in online course instruction and the expectations of students comfortable with using streaming video in their personal lives has led to instructors making more requests of librarians to supply films—both instructional and feature—through streaming. Staff at the University Libraries of the University of North Carolina at Greensboro (UNCG) responded to this need as they worked across departments to create efficient workflows, worked with distributors and conducted a pilot project to learn more about the current streaming film environment, established policies, offered technical support, and shared information with faculty by a variety of means.     

Advocacy for parents and carers involved with children's services: making a difference to working in partnership?

This paper explores findings from the evaluation of a scheme providing direct advocacy to parents where there were concerns about their ability to provide safe care for their children. The evaluation explored the views of service users, social workers and conference chairpersons and found general agreement that the advocacy scheme contributed positively to the process of working in partnership. This is of interest given research findings which suggest that working in partnership is particularly difficult in cases involving child protection issues. However, it is noted that there appears to be little political will to develop advocacy schemes for parents in the UK, and this is of concern given the lack of supports available to them to navigate a complex and often intimidating system.     

Mobilising towards and imagining homelands: diaspora formation among U.K. Sudanese

This paper examines diasporic identity formation among Sudanese migrants in the U.K. From constructivist perspectives, diasporas form when mobilisations towards a ‘homeland’ initiate processes of collectively imagining that homeland. These mobilising agendas have been analysed as either emotional and/or political and correspond to processes of collective remembering, forgetting or future-making. Drawing on interviews with, and observations of, Sudan-born residents of the U.K., this paper examines diaspora formation among U.K. Sudanese. It asks what mobilising agendas unite U.K. Sudanese and what kinds of imaginative processes orient them towards their shared homeland(s). This investigation uncovers how multiple and seemingly contradictory processes of diasporic identity formation overlap within the same ‘national’ migrant community. It analyses how different mobilising agendas initiate imaginative processes of ‘past-making’ and ‘future-making’ which correspond to various types of diasporic identity. In doing so, this paper contributes to debates within constructivist approaches to diaspora formation.     

Parameter change test for zero-inflated generalized Poisson autoregressive models

In this paper, we consider the problem of testing for parameter change in zero-inflated generalized Poisson (ZIGP) autoregressive models. We verify that the ZIGP process is stationary and ergodic and that the conditional maximum likelihood estimator (CMLE) is strongly consistent and asymptotically normal. Based on these results, we construct CMLE- and residual-based cumulative sum tests and show that their limiting null distributions are a function of independent Brownian bridges. The simulation results are provided for illustration. A real data analysis is performed on some crime data of Australia.     

The Changing Impact of Industry,Household Structure,and Residence on Household Weil-Being1

Abstract The changing impact of industry, household structure, and residence on household well-being during the 1980s is examined with data from the Current Population Survey for 1981–1982 and 1990–1991. Findings indicate that household well-being was greatest for those families relying on traditional higher-wage industries (high-wage manufacturing, government, mining). The well-being of families relying on higher-wage services was lower, most likely a consequence of the prevalence of marginal and low-paying jobs in the service sector. Rewards associated with employment in construction and low-wage manufacturing were not consistently greater than those associated with employment in low-wage services. While changes in the impact of industry were minor, significant changes occurred in the impact of an additional earner on economic well-being over the decade. Results indicate that increasing hardship has been experienced by vulnerable populations, such as nonmetropolitan and single-headed families, and minority households, particularly Hispanics. Implications for economic development strategies and work-related assistance programs are highlighted.     

The Significance of Socioeconomic and Ethnic Diversity for the Risk Communication Process

Risk communication is being characterized as one way of facilitating more effective, democratic and participatory risk management strategies. An emphasis on formal communication approaches as a means to improve decisions and decrease conflict will highlight the challenge of managing hazards within a culturally heterogeneous society. Communication and participatory strategies will be considered successful only if diverse communities can be engaged as partners in the policy process. Because responses to risks are embedded and evolve within broader social environments, achieving the promise of risk communication across a diverse society may not be possible absent an understanding of how sociocultural variables and past experiences shape the exchange of ideas or information in any particular situation. This paper considers the implications of ethnic and socioeconomic variability for the risk communication process, summarizing theoretical perspectives and empirical evidence on the link between sociocultural features and risk responses. Specifically, the factors that define the context of communication may influence: the initial framing of a risk issue, particularly, the adoption of an environmental justice vs. scientific/economic perspective; the perceived importance of various aspects of the decision problem; and prior beliefs about environmental hazards and agencies involved in risk management. Two examples of situations requiring communications about risk are presented and illustrate how these principles could operate in minority or lower-income communities. A significant challenge for health and regulatory officials will be to engage in an interactive process of information and opinion exchanges that is reasonable and effective within vastly different socioeconomic and cultural contexts.     

Meeting the Needs of the Adoption Triangle Through Open Adoption: The Birthmother

Open adoption is a relatively new and controversial practice. However, in many cultures this practice is traditional. In this first of a series of articles, the affect of open adoption upon birthparents is discussed. The open process facilitates appropriate grieving, enables decision making and furthers the growth of the birthmother.     

On double hysteretic heteroskedastic model

ABSTRACT

This paper proposes a hysteretic autoregressive model with GARCH specification and a skew Student's t-error distribution for financial time series. With an integrated hysteresis zone, this model allows both the conditional mean and conditional volatility switching in a regime to be delayed when the hysteresis variable lies in a hysteresis zone. We perform Bayesian estimation via an adaptive Markov Chain Monte Carlo sampling scheme. The proposed Bayesian method allows simultaneous inferences for all unknown parameters, including threshold values and a delay parameter. To implement model selection, we propose a numerical approximation of the marginal likelihoods to posterior odds. The proposed methodology is illustrated using simulation studies and two major Asia stock basis series. We conduct a model comparison for variant hysteresis and threshold GARCH models based on the posterior odds ratios, finding strong evidence of the hysteretic effect and some asymmetric heavy-tailness. Versus multi-regime threshold GARCH models, this new collection of models is more suitable to describe real data sets. Finally, we employ Bayesian forecasting methods in a Value-at-Risk study of the return series.
