    The Conway-Maxwell-Poisson distribution: distributional theory and approximation

    Get PDF
    The Conway-Maxwell-Poisson (CMP) distribution is a natural two-parameter generalisation of the Poisson distribution which has received some attention in the statistics literature in recent years by offering flexible generalisations of some well-known models. In this work, we begin by establishing some properties of both the CMP distribution and an analogous generalisation of the binomial distribution, which we refer to as the CMB distribution. We also consider some convergence results and approximations, including a bound on the total variation distance between a CMB distribution and the corresponding CMP limit.Comment: 26 page

    Working Effectively with Employees who Have Epilepsy

    Get PDF
    This brochure on employees who have epilepsy and the Americans with Disabilities Act (ADA) is one of a series on human resources practices and workplace accommodations for persons with disabilities edited by Susanne M. Bruyùre, Ph.D., CRC, SPHR, Director, Program on Employment and Disability, School of Industrial and Labor Relations – Extension Division, Cornell University. Cornell University was funded in the early 1990’s by the U.S. Department of Education National Institute on Disability and Rehabilitation Research as a National Materials Development Project on the employment provisions (Title I) of the ADA (Grant #H133D10155). These updates, and the development of new brochures, have been funded by Cornell’s Program on Employment and Disability, the Pacific Disability and Business Technical Assistance Center, and other supporters

    Indigenous belief in a just world: New Zealand Māori and other ethnicities compared

    Get PDF
    Striking differences in economic outcomes exist within New Zealand for Māori relative to the non-Māori population. This paper analyses whether certain beliefs and values differ systematically between Māori and non-Māori, while recognising that there is not a uniform culture for either group. Many of the beliefs and values we examine have been linked to the adoption of particular individual actions that may affect economic outcomes. For example, prior research indicates a person who believes that the world is not ‘just’, in the sense of believing that success is due to luck and connections rather than individual effort, may not be motivated to seek educational achievements, nor see the point of working hard at a job

    Stable isotope analysis of human hair and nail samples: the effects of storage on samples

    Get PDF
    When submitting samples for analysis, maintaining sample integrity is essential. Appropriate packaging must be used to prevent damage, contamination or loss of sample. This is particularly important for stable isotope analysis by isotope ratio mass spectrometry as this technique is capable of detecting subtle differences in isotopic composition with great precision. In a novel study, scalp hair and fingernail samples were placed in five different types of packaging, routinely used in forensic laboratories and stored for 6 weeks and 6 months. Samples were subsequently cleaned and submitted for 13C/12C, 15N/14N, 2H/1H and 18O/16O analysis. Results from 13C analysis indicate that type of packaging can cause slight changes in 13C abundance over time. Differences were noted in the 15N isotope signatures of both hair and nail samples after 6-week storage, but not after 6 months. This apparent discrepancy could be a result of the packaging not being properly sealed in the 6 weeks study. Fewer differences were noted when analyzing samples for 2H and 18O abundance
