Erectile dysfunction frequently occurs with diabetes mellitus. A survey of diabetic men was conducted by anonymous questionnaire to investigate the associations of erectile dysfunction with various predictive factors. A total of 112 diabetic males without an obvious history of erectile dysfunction were available for analyses. The mean age and duration of diabetes were 53.7?±?12.2 years and 10.2?±?8.6 years (mean?±?standard deviation), respectively. The questionnaire included questions on the presence or absence of smoking, hypertension, libido and subjective symptoms of diabetic neuropathy that may be associated with erectile dysfunction. Analysis of the answers to the questionnaire revealed that 40% of the patients complained of erectile dysfunction (erection ‘always insufficient’). Erectile dysfunction was significantly correlated with age (p?=?0.005), but not with duration of diabetes (p?=?0.25), adjusted for age. Erectile dysfunction was also associated with sensory neuropathy and reduced libido, independently of age. The logistic regression analysis revealed that erectile dysfunction was positively associated with reduced libido and age. The odds ratio of erectile dysfunction for reduced compared to unreduced libido was 18.21, suggesting that psychogenic factors have a marked influence on erectile dysfunction. It is concluded that the presence of erectile dysfunction should be considered when symptoms related to diabetic neuropathy are observed; psychological approaches, such as sexual counseling, could be applied for the treatment of erectile dysfunction.  相似文献

The objective of this study was to evaluate the shape of anterior–posterior curvatures of the spine and to determine the values of body symmetry deviations in the frontal plane, in elderly males. The study group consisted of 34 males aged between 61 and 83 years, attending two hour-long training sessions a week. The comparative group consisted of 30 students. The photogrammetric method based on the Moire phenomenon was used to evaluate the body posture. The obtained data confirm characteristic tendencies of physiological spinal curvatures to change with the aging process. A decrease of the lumbar–sacral spinal-segment inclination and an increase of the upper thoracic spinal-segment inclination were observed in the elderly males. Whereas, the value of thoracic kyphosis lower-segment inclination was similar to the value obtained in young adult males. The stated differences indicate a flattening of lumbar lordosis and a deepening of the upper arch of thoracic kyphosis, which results in a characteristic body posture in the standing position with the head protruding and the upper trunk segment inclined. The above-mentioned observations indicate a dominance of the angular thoracic kyphosis value over the remaining spinal curvatures. These differences occur to a greater degree in elderly males.  相似文献

There is a lack of research investigating Pacific peoples' gambling within a New Zealand context. In this paper, data about gambling activity (rather than problem gambling) are presented from the first data collection point for a cohort of mothers who are part of the longitudinal Pacific Islands Families study. The results indicate that gambling behaviour could be influenced by cultural differences. For example, Tongans are more likely to gamble than Samoans, and those who undertake traditional gift giving customs are likely to spend more money on gambling than those who do not. This paper identifies a need for research on Pacific peoples' gambling to acknowledge ethnic-specific cultural influences on gambling practices.  相似文献

In the context of the academic interest shown in the enduring transnationalism of contemporary migrants and in the modes of transitions to adulthood in different global settings, in this article we examine the transnational lives of adolescents moving between Vancouver (Canada) and Hong Kong. While there is a lot of literature on the parents' political and economic calculations, there is very little on how adolescents in these situations articulate their geographical sensibilities. We draw on three periods of fieldwork undertaken in 2002, 2008 and 2010 during which we employed a transnational methodology to interview young people in Vancouver and Hong Kong. We argue that becoming an adult involves a process in which, in their discussions about the geographical and emotional distance between themselves and their families, young people articulate their own complex emotions towards specific places in their transnational social field. Their families sporadically interrupt the adolescents' otherwise independent lives with fragmented modes of supervision. By examining the complex intentions and emotions behind circular migration from the perspective of transnational youth in a community of split families, we advance the discussion on transnational geographies, particularly of the family in the context of a flexible global economy.  相似文献

Through a Personal Emergency Link system, the Senior Citizen Home Safety Association has rendered 24-hour care to more than 111,000 service users in Hong Kong who are mostly vulnerable seniors and chronic invalids living alone or living with their elderly spouses/caregivers only. This article will describe how the Personal Emergency Link system is used to link seniors living in the community. Measures taken to prevent failure of the system will be described. With the use of different technology applications, many human touches and warm caregiving are rendered to the elderly and needy.  相似文献

The authors develop four exercises to further explore themes that are discussed in the Waldner and Dobratz article “Graffiti as a Form of Contentious Political Participation (Sociology Compass 7: 377–389),” including Mothers of the Plaza de Mayo (Madres de Plaza de Mayo), From Famous Political Speech (“Ich Bin Ein Berliner”) to Graffiti: “Ich bin Berliner”, “Protest, Violence, and Graffiti in Greek Politics,” and “Political Speech or Just Tagging: Billboards and Culture Jamming.” The authors encourage students to explore them such as motivations for graffiti, the difficulty in discerning writer intent, the use of graffiti as a form of political protest, and the historical and geographical context of graffiti. The authors provide links to YouTube videos and supplementary readings.  相似文献

L'État providence Canadien est déséquilibré: leader mondial dans certains domaines de l'investissement social—plus particulièrement en soins de santé et enseignement supérieur—il traîne dans d'autres domaines de la dépense d'aide sociale, y compris les politiques de garde d'enfants. Nous constatons qu'aujourd'hui la résistance dans la plupart des régions du Canada à la politique de garde d'enfants universel a des racines historiques profondes. Elle est de fait intégré dans le cadre même du bien‐être social canadien: le contrat de citoyenneté sociale. Nous employons une approche de “bas en haut” sur l'état du bien‐être en nous concentrant sur la façon dont les acteurs collectifs, en particulier, les féministes de la première vague et leurs contemporains au sein des organisations du mouvement ouvrier, ont encadrées et caractérisé la citoyenneté sociale féminine; Nous constatons que l'exclusion de l'adhésion des femmes employées tronque les possibilités discursives par lesquelles des revendications pour des provisions universelles de bien‐être sociale pourraient être apportées. Canada's welfare state is lopsided: while leading the world in some areas of social investment—most notably health care and higher education—it is a laggard in other areas of social welfare spending, including childcare policies. We find that policy resistance to universal childcare in most regions of Canada today has deep historical roots and is, indeed, embedded into the very framework of the Canadian welfare state: the social citizenship contract. We employ a “bottom‐up” perspective on the welfare state focusing on how collective actors, in particular, first‐wave feminists and their contemporaries within labor movement organizations, framed and characterized female social citizenship in ways that excluded employed women from full membership and, in this, truncated discursive opportunities by which claims for universal welfare state provisions could be made.  相似文献

In modeling disease transmission, contacts are assumed to have different infection rates. A proper simulation must model the heterogeneity in the transmission rates. In this article, we present a computationally efficient algorithm that can be applied to a population with heterogeneous transmission rates. We conducted a simulation study to show that the algorithm is more efficient than other algorithms for sampling the disease transmission in a subset of the heterogeneous population. We use a valid stochastic model of pandemic influenza to illustrate the algorithm and to estimate the overall infection attack rates of influenza A (H1N1) in a Canadian city.  相似文献

To capture mean and variance asymmetries and time‐varying volatility in financial time series, we generalize the threshold stochastic volatility (THSV) model and incorporate a heavy‐tailed error distribution. Unlike existing stochastic volatility models, this model simultaneously accounts for uncertainty in the unobserved threshold value and in the time‐delay parameter. Self‐exciting and exogenous threshold variables are considered to investigate the impact of a number of market news variables on volatility changes. Adopting a Bayesian approach, we use Markov chain Monte Carlo methods to estimate all unknown parameters and latent variables. A simulation experiment demonstrates good estimation performance for reasonable sample sizes. In a study of two international financial market indices, we consider two variants of the generalized THSV model, with US market news as the threshold variable. Finally, we compare models using Bayesian forecasting in a value‐at‐risk (VaR) study. The results show that our proposed model can generate more accurate VaR forecasts than can standard models.  相似文献
