The Economic Casualties of Retiring Because of Unemployment

This research reports on one aspect of a multimethod study which investigated the effect of involuntary retirement on retirement income. Using the Survey on Ageing and Independence 1991, a secondary data analysis was carried out which examined the economic effects of retiring because of unemployment. This analysis was followed by interviews with 33 men and women whose retirement was induced by unemployment. In the secondary analysis, when the respondents who retired for reasons of unemployment were compared to those who retired for other reasons, there was little doubt that the unemployment retirees were disadvantaged on human capital variables, in terms of their work history, and ultimately, in their retirement income, whether personal or household. Returning to work part-time after retirement did not appear to raise their incomes which were lower than the incomes of those who retired for other reasons. Furthermore, they were more likely to receive government transfer payments such as disability benefits or social assistance. When the factors that significantly contributed to their income in retirement were considered they were a function of personal wealth such as investments and a private pension. The public pension system did not have a significant influence on their retirement income. In the convenience sample, all respondents reported that unemployment lead to a drop in retirement income. For those most severely hit by unemployment, the transition period was extremely stressful with people reporting high levels of anger, depression, and sadness and constant worry about their straitened circumstances. People coped with their drop in income by changing their lifestyle, giving up valued assets like their homes and dipping into their savings and RRSPs. These strategies, in turn, depleted their resources for retirement and caused considerable consternation about what they saw as an uncontrollable and unforeseeable future. People also relied heavily on social assistance and disability benefits to survive until the age where they were eligible to draw down their retirement benefits. When they had to draw down their retirement pensions earlier than expected, they were frustrated because they had to accept lower pensions, a feeling that was compounded when they discovered that, if they were lucky enough to secure part-time work, this resulted in further reductions in their pensions. The incongruity of government retirement policy threats of cutbacks to pensions or raising the age of retirement -- did not escape most retirees in our sample and served to create more uncertainty and stress for an already economically distressed group of Canadians.retirement income; SAI; unemployment

The Economic Casualties of Retiring Because of Poor Health

This multimethod study investigated the effect of involuntary retirement on retirement income. Using the General Social Survey 1994, a secondary data analysis was carried out which examined the economic effects of retiring because of poor health. When the men and women who retired for reasons of poor health were compared to those who retired for other reasons, there was little doubt that the health retirees were disadvantaged on human capital variables, in terms of their work history, and ultimately, in their retirement income, whether personal or household. The men who retired because of ill health did not appear to benefit from government transfer payments and were less likely to receive income from a private pension or from interest and dividends. The women retirees suffered from the same disadvantages as the men, however, when they reached retirement they were more likely to rely on government transfer payments as a major source of income. Like the men, they were more likely to believe that their retirement income had gotten worse since the day they retired, and, over two-thirds believed that their financial situation had become much worse. In the multivariate analyses, however, any effect that poor health might have had on household income was offset by the benefits associated with marriage, and their own sociodemographic characteristics. This is further confirmed when personal income is considered, since marriage has the strong and negative influence on personal income. The interviews with the retirees indicated that retiring for reasons of poor health was seen by most people as a somewhat unpleasant transition that had long lasting and negative effects on retirement income.GSS; poor health; retirement

Designing a Fusion Power Plant with Superconducting Training Magnets

Fusion power has the potential to revolutionise global energy production with a reliable, low CO2 (not zero due to the use of steel, concrete etc. that typically produce CO2 during manufacture), low radioactivity power supply, that is readily available at the point of need. The ITER and SPARC reactors are already under construction, with plans to begin full-power (Qfus ≥ 10) operation in the early 2030s; proving that fusion is a viable energy source. To see wide adoption however, reactors must be made as commercially attractive as possible. Here we present superconducting pilot reactor designs that have been optimised for minimum capital cost using the PROCESS systems code. Key design choices were made using technologies that are either available now or already in development; with concentrated effort these reactors could be built on 2030-2040 timescales. We focus primarily on the reactor from this set with the lowest overall capital cost, our “preferred” reactor: a 100 MW net electricity producing tokamak with REBCO superconducting toroidal field coils and central solenoid and Nb-Ti superconducting poloidal field coils. In addition, we have investigated using ductile, remountable Nb-Ti training coils (named after the training wheels of children’s bicycles) during the commissioning phase of a reactor to remove the risk of brittle failure of the full-power magnets during this stage. Such magnets would operate at lower field, but would enable thorough machine testing. Finally, we investigate and predict how advances in magnet technologies could effect our preferred reactor design and cost, and conclude that the effects of such advances do not justify waiting yet longer before beginning detailed reactor design and construction

Phylogenetic Relationships in Pterodroma Petrels Are Obscured by Recent Secondary Contact and Hybridization

The classification of petrels (Pterodroma spp.) from Round Island, near Mauritius in the Indian Ocean, has confounded researchers since their discovery in 1948. In this study we investigate the relationships between Round Island petrels and their closest relatives using evidence from mitochondrial DNA sequence data and ectoparasites. Far from providing clear delimitation of species boundaries, our results reveal that hybridization among species on Round Island has led to genetic leakage between populations from different ocean basins. The most common species on the island, Pterodroma arminjoniana, appears to be hybridizing with two rarer species (P. heraldica and P. neglecta), subverting the reproductive isolation of all three and allowing gene flow. P. heraldica and P. neglecta breed sympatrically in the Pacific Ocean, where P. arminjoniana is absent, but no record of hybridization between these two exists and they remain phenotypically distinct. The breakdown of species boundaries in Round Island petrels followed environmental change (deforestation and changes in species composition due to hunting) within their overlapping ranges. Such multi-species interactions have implications not only for conservation, but also for our understanding of the processes of evolutionary diversification and speciation

Australian and New Zealand Pulmonary Rehabilitation Guidelines

Background and objective: The aim of the Pulmonary Rehabilitation Guidelines (Guidelines) is to provide evidence-based recommendations for the practice of pulmonary rehabilitation (PR) specific to Australian and New Zealand healthcare contexts. Methods: The Guideline methodology adhered to the Appraisal of Guidelines for Research and Evaluation (AGREE) II criteria. Nine key questions were constructed in accordance with the PICO (Population, Intervention, Comparator, Outcome) format and reviewed by a COPD consumer group for appropriateness. Systematic reviews were undertaken for each question and recommendations made with the strength of each recommendation based on the GRADE (Gradings of Recommendations, Assessment, Development and Evaluation) criteria. The Guidelines were externally reviewed by a panel of experts. Results: The Guideline panel recommended that patients with mild-to-severe COPD should undergo PR to improve quality of life and exercise capacity and to reduce hospital admissions; that PR could be offered in hospital gyms, community centres or at home and could be provided irrespective of the availability of a structured education programme; that PR should be offered to patients with bronchiectasis, interstitial lung disease and pulmonary hypertension, with the latter in specialized centres. The Guideline panel was unable to make recommendations relating to PR programme length beyond 8 weeks, the optimal model for maintenance after PR, or the use of supplemental oxygen during exercise training. The strength of each recommendation and the quality of the evidence are presented in the summary. Conclusion: The Australian and New Zealand Pulmonary Rehabilitation Guidelines present an evaluation of the evidence for nine PICO questions, with recommendations to provide guidance for clinicians and policymakers

Feasibility of an incentive scheme to promote active travel to school: a pilot cluster randomised trial

Abstract Background In Great Britain, 19% of trips to primary school within 1 mile, and 62% within 1–2 miles, are by car. Active travel to school (ATS) offers a potential source of moderate-to-vigorous physical activity (MVPA). This study tested the feasibility of an intervention to promote ATS in 9–10 year olds and associated trial procedures. Methods A parallel cluster randomised pilot trial was conducted over 9 weeks in two schools from a low-income area in northeast England. Measures included daily parental ATS reports (optionally by SMS) and child ATS reports, as well as accelerometry (ActiGraph GT3X+). At baseline, all children were asked to wear the accelerometer for the same week; in the post-randomisation phase, small subsamples were monitored each week. In the 2 weeks when a child wore the accelerometer, parents also reported the start and finish times of the journey to school. The intervention consisted of a lottery-based incentive scheme; every ATS day reported by the parent, whether by paper or SMS, corresponded to one ticket entered into a weekly £5 voucher draw. Before each draw session, the researcher prepared the tickets and placed them into an opaque bag, from which one was randomly picked by the teacher at the draw session. Results Four schools replied positively (3.3%, N = 123) and 29 participants were recruited in the two schools selected (33.0%, N = 88). Participant retention was 93.1%. Most materials were returned on time: accelerometers (81.9%), parental reports (82.1%) and child reports (97.9%). Draw sessions lasted on average 15.9 min (IQR 10–20) and overall session attendance was 94.5%. Parent-child report agreement regarding ATS was moderate (k = 0.53, CI 95% 0.45; 0.60). Differences in minutes of accelerometer-assessed MVPA between parent-reported ATS and non-ATS trips were assessed during two timeframes: during the journey to school based on the times reported by the parent (U = 390.5, p < 0.05, 2.46 (n = 99) vs 0.76 (n = 13)) and in the hour before classes (U = 665.5, p < 0.05, 4.99 (n = 104) vs 2.55 (n = 19)). Differences in MVPA minutes between child-reported ATS and non-ATS trips were also significant for each of the timeframes considered (U = 596.5, p < 0.05, 2.40 (n = 128) vs 0.81 (n = 15) and U = 955.0, p < 0.05, 4.99 (n = 146) vs 2.59 (n = 20), respectively). Conclusions Data suggest the feasibility of an ATS incentive scheme and of most trial procedures. School recruitment stood out as requiring further piloting.

Physical training in boys with Duchenne Muscular Dystrophy: the protocol of the No Use is Disuse study

Contains fulltext : 89740.pdf (publisher's version ) (Open Access)BACKGROUND: "Use it or lose it" is a well known saying which is applicable to boys with Duchenne Muscular Dystrophy (DMD). Besides the direct effects of the muscular dystrophy, the increasing effort to perform activities, the fear of falling and the use of personal aids indirectly impair leg and arm functions as a result of disuse. Physical training could oppose this secondary physical deterioration. The No Use is Disuse (NUD) study is the first study in human subjects with DMD that will examine whether a low-intensity physical training is beneficial in terms of preservation of muscle endurance and functional abilities. The study consists of two training intervention studies: study 1 "Dynamic leg and arm training for ambulant and recently wheelchair-dependent boys with DMD and, study 2 "Functional training with arm support for boys with DMD who have been confined to a wheelchair for several years". This paper describes the hypotheses and methods of the NUD study. METHODS: Study 1 is an explorative randomized controlled trial with multiple baseline measurements. Thirty boys with a DNA-established diagnosis of DMD will be included. The intervention consists of a six-months physical training during which boys train their legs and arms with active and/or assisted cycling training equipment. The primary study outcomes are muscle endurance and functional abilities, assessed with a Six-Minute Bicycle Test and the Motor Function Measure. Study 2 has a within-group repeated measurements design and will include ten boys with DMD who have already been confined to a wheelchair for several years. The six-months physical training program consists of 1) a computer-assisted training and 2) a functional training with an arm support. The primary study outcome is functional abilities of the upper extremity, assessed with the Action Research Arm Test. DISCUSSION: The NUD study will fill part of the gap in the current knowledge about the possible effects of training in boys with DMD and will increase insight into what type of exercise should be recommended to boys with DMD. The study will finish at the end of 2010 and results are expected in 2011. TRIAL REGISTRATION: The Netherlands National Trial Register1631
