Evaluation of the parameters of su by rational fractions

A rational fraction approximation is given for a function of one of the parameters defining Johnson's S_UError assessment for a segment of the domain of validity shows remarkable accuracy.     

Mapping the social geographies of autism – online and off-line narratives of neuro-shared and separate spaces

This paper draws together empirical work that has been produced by the authors in two different autistic spaces: the Swedish magazine Empowerment produced by and aimed at adults with autism, and English-speaking autistic communities online. While the two points of data collection are quite different, there are important points of commonality that enable us to explore central issues concerning autistic and neurotypical space and the meanings assigned to these in different contexts. The paper aims to introduce the notion of social geographies of autism, based on talks among adults with autism and a social movement to promote autistic identities, giving examples from our previous work that has spanned both online and off-line spaces. Key issues discussed in the paper include a focus on autistic political platforms and the carving out of both social and political spaces for people with autism. In doing so, neuro-separate and neuro-shared spaces must be negotiated.     

Maximum likelihood estimation of the bimodal failure rate for censored and tied observations

DIMITROV, RACHEV and YAKOVLEV ( 1985 ) have obtained the isotonic maximum likelihood estimator for the bimodal failure rate function. The authors considered only the complete failure time data. The generalization of this estimator for the case of censored and tied observations is now proposed.     

Immigrants and Employer-provided Training

Much has been written about the labour market outcomes for immigrants in their host countries, particularly with regard to earnings, employment and occupational attainment. However, much less attention has been paid to the question of whether immigrants are as likely to receive employer-provided training relative to comparable natives. As such training should be crucial in determining the labour market success of immigrants in the long run it is a critically important question. Using data from a large-scale survey of employees in Ireland, we find that immigrants are less likely to receive training from employers, with immigrants from the New Member States of the EU experiencing a particular disadvantage. The immigrant training disadvantage arises in part from a failure on the part of immigrants to get employed by training-oriented firms. However, they also experience a training disadvantage relative to natives within firms where less training is provided.     

One-machine scheduling to minimize mean tardiness with minimum number tardy

In this paper the one-machine scheduling problem with the objective of minimizing the mean tardiness subject to maintaining a prescribed number of tardy jobs is analysed. An algorithm for solving this problem is presented. It is proved that the schedule generated by the proposed algorithm is indeed optimal.     

A further examination of antecedents of correctional staff life satisfaction

Working in corrections is not only a demanding job, but a socially important one. While a growing number of studies have examined how the work environment impacts the job stress, job satisfaction, and organizational commitment of staff, very few studies have examined how working in corrections impacts the life satisfaction of workers. The current study utilized OLS regression to examine the antecedents of life satisfaction among staff at a Midwestern private prison. Job satisfaction had a positive relationship with life satisfaction, while age, work on family conflict, family on work conflict, and job involvement all had statistically significant negative effects. Finally, perceptions of the level of financial rewards, job stress, organizational commitment, gender, race, educational level, tenure, supervisory status, position, marital status, and having children, all had non-significant associations with overall satisfaction with life.     

Children's response to the medical visit for allegations of sexual abuse: maternal perceptions and predicting variables

This study examined maternal perceptions of their child's response to the medical evaluation for alleged sexual abuse. A total of 50 mothers were interviewed 6 months after a visit to a Child Protection Clinic for a medical evaluation of alleged sexual abuse. The mothers answered a questionnaire on their child's reactions to the medical visit. More than 60% of children were perceived as being reassured about physical integrity. The degree of psychological distress was independent of perpetrator's identity and severity of the abuse. Mothers considered that a hypothetical second visit would generate in their child a level of anxiety that increased with perceived intensity of fear of the examination and decreased with perceived kindness of the physician. These results suggest that the physician's behaviour during the medical evaluation for alleged sexual abuse has an influence on the child's degree of distress that is independent of type and severity of abuse.
