Prediction theory for autoregressivemoving average processes

This paper reviews statistical prediction theory for autoregressive-moving average processes wing techniques developed in control theory. It demonstrates explicitly the connectioluns between the statistical and control theory literatures. Both the forecasting problem and the Single extraction problem am considered, udng linear least squares methods. Whereas the classical Statistical theory developed by Wiener and Kolmogomv is restricted to stationary stochaotic processes, the recursive techniques known as the Kalman filter are shown to provide a satisfactory treatment of the difference-stationary care and other more general cases. Complete results for non-invertible moving averages are also obtained.     

Young Adult Carers: The Impact of Caring on Health and Education

Research has shown that young people who care for parents and relatives (young carers and young adult carers) are at greater risk of mental and emotional difficulties and are more likely to do badly at school or college. To explore the difficulties faced by young adult carers (aged 14–25) in the UK, an online survey was conducted. Almost half (45%) of the 295 respondents reported having a mental health problem. The relationship between the extent of caring and perceived mental health problems and the impact of caring responsibilities on work and education were investigated.     

Modeling perceived job productivity and its antecedents considering gender as a moderator

This study proposes a conceptual model for examining the formation of perceived job productivity and its antecedents. In the model, leader–member exchange and job satisfaction both directly and indirectly influence perceived job productivity, with the latter effect occurring through the mediation of organizational commitment. Gender moderates each model path. The moderating effects are simultaneously tested using data from 344 engineering staff of a large Taiwanese high-tech manufacturer. Lastly, the empirical findings and their implications are discussed.     

Connecting Print Patrons to Electronic Holdings with Shelf Dummies

After a two-year renovation, the Kent State University Music Library reopened as the Performing Arts Library. Before the closure, some serials were sent to the depository or reclassified within the library. In order to assist patrons browsing print journals or searching for articles in the stacks, library staff created shelf dummies detailing print and electronic holdings information as well as indexing for each title. Patron feedback has been positive, and the project has helped both library staff and patrons better understand accessibility and location of journals.     

Those Who are Left Behind: An Estimate of the Number of Family Members of Suicide Victims in Japan

This paper contributes to the literature of suicide studies by presenting procedures and its estimates of the number of family members who lose their loved ones to suicide. Using Japanese aggregate level data, three main findings emerge: first, there are approximately five bereaved family members per suicide; second, in 2006, there were about 90,000 children who had lost a parent to suicide; and third, in 2006, there were about three million living family members who had lost a loved one to suicide. The direct production loss of bereaved family members in 2006 alone is estimated at approximately 197 million USD. These results are valuable in evaluating the cost-effectiveness of suicide prevention programs and in designing appropriate policy instruments.     

Measures of occupational status in a special population

Previous research has shown that indirect measures of occupational status such as the Duncan Socioeconomic Index (SEI) are more valid than direct measures of occupational prestige, such as those developed by the National Opinion Research Center and by Treiman, for analyses of social mobility. The Professional, Technical, and Kindred (PTK) occupations available for the SEI are a biased sample of all PTK occupations. Do findings on the validity of the SEI pertaining to the general population hold for special populations, such as college graduates? Confirmatory factor analysis comparing the validities of four measures of occupational SES—the SEI, a 1960 counterpart of the SEI developed by Siegel and based on all Census occupations, the NORC prestige scale, and the Treiman international prestige scale—showed that the indirect measure developed by Siegel was clearly more valid than the other three measures. Since these findings indicate that the predictors in a regression equation are more valid than the criterion, there is some question as to what the criterion should really be.     

Evidence-Based Suicide Prevention Screening in Schools

Screening for suicidality, as called for by the President's New Freedom Commission on Mental Health, is a major public health concern. As a place where adolescents spend a considerable amount of their waking hours, school is an important venue for screening adolescents for suicidal behaviors and providing preventive education and risk management. Social workers, as the largest occupational group of mental health professionals in the United States, have a significant role to play in the national strategy to prevent youth suicide, especially at the school level. This article reviews the literature on suicide prevention screening, warning signs, and risk factors to gain a better understanding of evidence-based screening strategies and discuss the implications for school social workers, counselors, and psychologists. It focuses on the identification of research-based information and explication of potential means for guiding preventive screening and clinical practice with suicidal adolescents.     

Counting Young Carers in Switzerland – A Study of Prevalence

An online survey of children in school grades 4–9 (mostly aged 10–15) was conducted in order to determine the prevalence of young carers in Switzerland using a 2‐stage stratified sampling approach. 4082 respondents were drawn from 230 schools. A total of 3991 respondents were included in the analysis and of these 307 (7.7%) were identified as young carers. The population estimate of prevalence was 7.9 per cent. This suggests that there are around 38 400 young carers in school grades 4–9 in Switzerland. Extrapolating to the 9–16 age group gives a figure of almost 51 500.
