A Decision Theory Perspective on the Disposal of High-Level Radioactive Waste

In this paper the problem of high-level nuclear waste disposal is viewed as a five-stage, cascaded decision problem. The first four of these decisions having essentially been made, the work of recent years has been focused on the fifth stage, which concerns specifics of the repository design. The probabilistic performance assessment (PPA) work is viewed as the outcome prediction for this stage, and the site characterization work as the information gathering option. This brief examination of the proposed Yucca Mountain repository through a decision analysis framework resulted in three conclusions: (1) A decision theory approach to the process of selecting and characterizing Yucca Mountain would enhance public understanding of the issues and solutions to high-level waste management; (2) engineered systems are an attractive alternative to offset uncertainties in the containment capability of the natural setting and should receive greater emphasis in the design of the repository; and (3) a strategy of waste management should be adopted, as opposed to waste disposal, as it allows for incremental confirmation and confidence building of a permanent solution to the high-level waste problem.     

Elderly prisoners: a growing and forgotten group within correctional systems vulnerable to elder abuse

There are over 2.1 million people incarcerated in the nation's jails and prisons. Additionally, close to 600,000 prisoners are released annually into communities across the country. Many prisoners and those released from prisons are elderly. The purpose of this article is to examine the systemic abuse and neglect experienced by elderly prisoners while they are incarcerated and when they are released from prison. Most correctional systems have inadequate resources, processes, and personnel to manage the elderly population inside and outside of prisons. In addition to providing a definition of "elderly prisoner," two specific problems-prison health care and prisoner re-entry-are examined in the article. The article concludes with recommendations for both policy and research on how best we can further understand and address the multiple needs and concerns faced by elderly prisoners.     

Is Video-Game Playing a Risk Factor for Pathological Gambling in Australian Adolescents?

Very little research has been conducted to examine the relationship between video-game playing and gambling in adolescence. In this study, 2,669 adolescents aged 13–17 years were surveyed to obtained details of their involvement in gambling and video-game playing as well as a measure of pathological gambling (the DSM-IV-J). The results showed that, the frequency of video game playing was significantly related to pathological gambling, but that the effect size was very small and largely accounted for by the greater popularity of both activities amongst boys. There was some evidence for stronger associations between technologically similar activities, namely arcade video games and an interest in gaming machines, but other factors discussed in the paper may also account for this association. In summary, the findings suggested that playing video-games is unlikely to be a significant risk factor for pathological gambling during adolescence.

Work Hours,Schedules, and Insufficient Sleep Among Mothers and Their Young Children

Studies have linked parents' employment, work hours, and work schedules to their own sleep quality and quantity, but it is unclear whether these associations extend to children. The authors used data from the 5‐year in‐home survey of the Fragile Families and Child Wellbeing Study (N = 1,818) to examine the associations between maternal work hours and schedule and insufficient sleep among disadvantaged mothers and their young children. They found that mothers who worked more than 35 hours per week were more likely to experience insufficient sleep compared to mothers who worked fewer hours, whereas children were more likely to experience insufficient sleep when their mothers worked between 20 and 40 hours. Nonstandard work schedules were associated with an increased likelihood of insufficient sleep for mothers but not their children. The results highlight a potentially difficult balance between work and family for many disadvantaged working mothers in the United States.     

The morning after Canada’s Truth and Reconciliation Commission report: decolonisation through hybridity,ambivalence and alliance

Abstract

In Canada, 2015 will be remembered for the publication of the Truth and Reconciliation Commission Report which related to all Canadians the impacts of the Indian residential school system. The Commission invokes the United Nations Declaration on the Rights of Indigenous Peoples and uses the term reconciliation as a national strategy for moving forward. This paper employs an autoethnographic methodology and proposes that reconciliation might benefit by finding ways of confronting the Other within; I describe my reflections on a trip to the 2015 conference Learning at Intercultural Intersections at Thompson Rivers University. My social and cultural experiences as a Korean Canadian academic and administrator are challenged in order to consciously shift my own colonising mindset. Reconciliation in Canada will require significant personal, professional, institutional and sociocultural inquiry. What does it mean to discover the Other within? How do we walk with Indigenous peoples? How do educators come to be called ally by Indigenous peoples?     

Test–Retest Reliability in Infant Speech Perception Tasks

A long line of research investigates how infants learn the sounds and words in their ambient language over the first year of life, through behavioral tasks involving discrimination and recognition. More recently, individual performance in such tasks has been used to predict later language development. Does this mean that dependent measures in such tasks are reliable and can stably measure speech perception skills over short time spans? Our three laboratories independently tested infants with a given task and retested them within 0–18 days. Together, we can report data from 12 new experiments (total number of paired observations N = 409), ranging from vowel and consonant discrimination to recognition of phrasal units. Results reveal that reliability is extremely variable across experiments. We discuss possible causes and implications of this variability, as well as the main effects revealed by this work. Additionally, we offer suggestions for the field of infant speech perception to improve the reliability of its methodologies through data repositories and crowd sourcing.     

Estimating Housing Quality for Poverty and Development Policy Analysis: CWIQ in Ghana

Inadequate data on housing characteristics and lack of consensusregarding appropriate measures of housing quality characteristicsretard developments to meet housing needs of people in lessdeveloped countries. A constructed housing quality index is developed and Cronbach's alpha and factor analysis are employedeo evaluate its measurement properties. With data from the CoreWelfare Indicators Questionnaire (CWIQ) survey of 1997, theconstructed housing quality index identifies key factors relatedto housing quality in Ghana. Access to quality of life amenities contributes significant information and policy value to traditionalphysical attributes in modeling a housing quality index.     

Risk filtering, ranking, and management framework using hierarchical holographic modeling.

This paper contributes a methodological framework to identify, prioritize, assess, and manage risk scenarios of a large-scale system. Qualitative screening of scenarios and classes of scenarios is appropriate initially, while quantitative assessments may be applied once the set of all scenarios (hundreds) has been prioritized in several phases. The eight-phase methodology is described in detail and is applied to operations other than war. The eight phases are as follows: Phase I, Scenario Identification-A hierarchical holographic model (HHM) is developed to describe the system's "as planned" or "success" scenario. Phase II, Scenario Filtering-The risk scenarios identified in Phase I are filtered according to the responsibilities and interests of the current system user. Phase III, Bi-Criteria Filtering and Ranking. Phase IV, Multi-Criteria Evaluation. Phase V, Quantitative Ranking-We continue to filter and rank scenarios based on quantitative and qualitative matrix scales of likelihood and consequence; and ordinal response to system resiliency, robustness, redundancy. Phase VI, Risk Management is performed, involving identification of management options for dealing with the filtered scenarios, and estimating the cost, performance benefits, and risk reduction of each. Phase VII, Safeguarding Against Missing Critical Items--We examine the performance of the options selected in Phase VI against the scenarios previously filtered out during Phases II to V. Phase VIII, Operational Feedback-We use the experience and information gained during application to refine the scenario filtering and decision processes in earlier phases. These eight phases reflect a philosophical approach rather than a mechanical methodology. In this philosophy, the filtering and ranking of discrete scenarios is viewed as a precursor to, rather than a substitute for, consideration of the totality of all risk scenarios.
