Retirement Decisions of People with Disabilities: Voluntary or Involuntary

While some retirement is welcomed and on-time, other retirements are involuntary or forced due to the loss of a job, an early retirement incentive, a health problem, mandatory retirement, lack of control with too many job strains, or to provide care to a family member. An analysis of the 2002 Canadian General Social Survey reveals that 27% of retirees retired involuntarily. This research focuses on the disabled population in Canada and considers factors that influence voluntary and involuntary retirement. Further, consideration is given to the economic consequences of retiring involuntarily. This research will examine issues surrounding retirement and disability through statistical analysis of the Canadian Participation and Activity Limitations Survey (PALS) 2006 data. Methods include the use of descriptive statistics and logistic regression analysis to determine the characteristics associated with involuntary retirement. This study found that those who retired involuntarily were more likely to have the following socio-demographic and socioeconomic characteristics -- age 55 or less, less than high-school education, live in Quebec, rent their home, and have relatively low income. They were also more likely to be worse off financially after retirement and to be receiving social assistance or a disability benefit. In terms of disability, the likelihood of retiring involuntarily was greater for those with poor health at retirement, the age of onset was over 55, higher level of severity, and multiple types of disability. For the discussion, a social inequalities framework is used, where health selection into involuntary retirement depends on social location defined by age and education. Policy initiatives that reduce the effects of disability, and allow individuals to remain in or return to the labour force such as workplace accommodations are discussed.Retirement, Disabled, Health, Labour Force

Genome hyperevolution and the success of a parasite

The strategy of antigenic variation is to present a constantly changing population phenotype that enhances parasite transmission, through evasion of immunity arising within, or existing between, host animals. Trypanosome antigenic variation occurs through spontaneous switching among members of a silent archive of many hundreds of variant surface glycoprotein (VSG) antigen genes. As with such contingency systems in other pathogens, switching appears to be triggered through inherently unstable DNA sequences. The archive occupies subtelomeres, a genome partition that promotes hypermutagenesis and, through telomere position effects, singular expression of VSG. Trypanosome antigenic variation is augmented greatly by the formation of mosaic genes from segments of pseudo-VSG, an example of implicit genetic information. Hypermutation occurs apparently evenly across the whole archive, without direct selection on individual VSG, demonstrating second-order selection of the underlying mechanisms. Coordination of antigenic variation, and thereby transmission, occurs through networking of trypanosome traits expressed at different scales from molecules to host populations

Employer Pension Plan Inequality in Canada

The purpose of this research paper is to contribute to knowledge regarding employer pension plan (EPP) inequality in Canada. Information on EPP coverage and value is analyzed using the 1999 and 2005 Surveys of Financial Security. The results indicate that women, persons who may live alone, landed immigrants, and language minorities are at a disadvantage in their EPP coverage and accrued value. In addition, age, educational attainment, occupation, industry of employment, union membership, total personal income, province, and size of urban residence figure importantly in EPP coverage. Furthermore, age, educational attainment, industry of employment, total personal income, province and size of urban residence are all-important determinants of the termination value of EPPs. To identify inequalities in EPP coverage among the sub-populations, the researchers use multivariate analysis. This allows an identification of inequalities that are not a direct result of differences in age, gender, level of education, location, or position in the labour market. Findings indicate that differences in EPP coverage for women, persons who may live alone, landed immigrants and language minorities are primarily due to differences in these other characteristics. However, the lower EPP value witnessed by these subpopulations cannot be explained by individual or labour market characteristics.Employer Pension Plans, Registered Pension Plans, coverage, value, inequality, seniors, landed immigrants, gender differences, minority language

Highly-branched poly(N-isopropyl acrylamide)s with core-shell morphology below the lower critical solution temperature

YesHighly-branched poly(N-isopropyl acrylamide)s in water pass through coil-to-globule transitions. Using calorimetry and the colour change of a solvatochromic dye within the polymer, we show that some compositions have biphasic core–shell morphologies, with globular cores and open coil shells. The two-phase structure is favoured by increased branching and arises because the chain ends penetrate only to a limited degree into the polymer coil

Older Adults’ Awareness of Community Health and Support Services for Dementia Care

The article examines where older adults seek help in caring for a parent with dementia and the factors associated with their identification of community health and support services as sources of assistance. The authors conducted telephone interviews, using random digit dialing, of 1,152 adults aged 50 and over in the city of Hamilton. Respondents received a vignette that raised issues related to parental dementia. In identifying support sources, over 37 per cent of respondents identified their physician, 33 per cent identified informal support such as family and neighbors, and 31 per cent identified home health services. Only 18 per cent identified community support services. Female participants having higher levels of education were more likely to identify their physician as a source of support. Knowing where to find information about community support services was associated with an increased likelihood of mentioning physicians and home health services as sources of assistance.community support services , awareness , dementia , caregivers , vignette methodology

Comparative analysis of dinoflagellate chloroplast genomes reveals rRNA and tRNA genes

Background: Peridinin-containing dinoflagellates have a highly reduced chloroplast genome, which is unlike that found in other chloroplast containing organisms. Genome reduction appears to be the result of extensive transfer of genes to the nuclear genome. Unusually the genes believed to be remaining in the chloroplast genome are found on small DNA 'minicircles'. In this study we present a comparison of sets of minicircle sequences from three dinoflagellate species. Results: PCR was used to amplify several minicircles from Amphidinium carterae so that a homologous set of gene-containing minicircles was available for Amphidinium carterae and Amphidinium operculatum, two apparently closely related peridinin-containing dinoflagellates. We compared the sequences of these minicircles to determine the content and characteristics of their chloroplast genomes. We also made comparisons with minicircles which had been obtained from Heterocapsa triquetra, another peridinin-containing dinoflagellate. These in silico comparisons have revealed several genetic features which were not apparent in single species analyses. The features include further protein coding genes, unusual rRNA genes, which we show are transcribed, and the first examples of tRNA genes from peridinin-containing dinoflagellate chloroplast genomes. Conclusion: Comparative analysis of minicircle sequences has allowed us to identify previously unrecognised features of dinoflagellate chloroplast genomes, including additional protein and RNA genes. The chloroplast rRNA gene sequences are radically different from those in other organisms, and in many ways resemble the rRNA genes found in some highly reduced mitochondrial genomes. The retention of certain tRNA genes in the dinoflagellate chloroplast genome has important implications for models of chloroplast-mitochondrion interaction
