Aging male symptomatology and eating behavior

Objective: The literature on eating disorders in older males is still very limited. We assessed the relationship between aging male symptomatology and eating behavior in middle-aged and older men.

Method: We distributed anonymous questionnaires to men aged 40–75?years living in or near Innsbruck, Austria, covering demographic items, current eating disorder symptoms (as defined by DSM-5), and associated measures of eating pathology, body image, and sports activity (including exercise addiction). We also administered the Aging Males’ Symptoms scale (AMS), and classified respondents as “high-AMS” (AMS score ≥37; N?=?82) or “low-AMS” (AMS score <37; N?=?386).

Results: High-AMS men reported a significantly higher mean current BMI, a greater prevalence of eating disorder symptoms, higher scores on the Eating Disorder Examination Questionnaire, greater risk of exercise addiction, and more negative body image than low-AMS men.

Discussion: We found a marked association between aging-male symptomatology and eating-disorder symptomatology in aging men. Our findings suggest that clinicians should carefully inquire about eating disorder symptoms in men aged 40 and above reporting aging-male symptomatology. Importantly, several men in the study reported “purging” via excessive exercise (as opposed to the more common methods of vomiting or use of laxatives or diuretics), and therefore this should be a subject of inquiry in clinical evaluations. To pursue these findings, subsequent studies of eating disorders in older men should consider assessing endocrinological measures, particularly testosterone levels, and should use longitudinal designs.     

油气资源开发中的资源耗竭补偿标准

油气资源是可耗竭性资源,过度开采会损害子孙后代的利益。因此,油气资源税费体系应增加反映油气资源耗竭补偿的税费,以维护代际公平。油气资源耗竭补偿标准是研究油气资源耗竭补偿的难点和重点。采用使用者成本法对油气资源耗竭补偿标准进行研究,折现率和开采年限是两个重要参数。折现率选择时间偏好率,避免主观选择的随意性,开采年限应考虑新增储量。以中国2000—2014年数据测算,油气资源耗竭补偿标准为15%~22%,标准偏高。原因主要有两个:人均消费增长率偏高和开采年限偏低。     

Quality of Life in Older Adults: Benefits from Caring Services in Hong Kong

Many older adults are in need of care. Therefore, older people would generally benefit from the use of caring services, notably including home care, residential care, nursing, and medical services. The contributory factors underlying caring services tend to be a caring perspective that aspires to sustain older peoples social relationships and real-life involvement. To gauge the benefits from various social and health services, the present study relies on a large-scale survey of 3000 older adults in Hong Kong, using quality of life as a criterion. Results showed that an older adult who had used (ordinary or enhanced) home care services for a longer time turned out to have appreciably more improvement in quality of life. Besides, those who joined an interest group more frequently were higher in quality of life, including the health domain. On the other hand, frequent use of medical and meal-to-home services were signals that reflected problems detrimental to the older users quality of life. Despite this, the quality of clinics or hospitals, as perceived by the older adult, was the most beneficial. As such, caring services that foster older adults interests, cater to their health care needs, and embody quality can have principal contribution to their users quality of life.

特殊都市社区旅游开发研究——以广州沙面为例

社区旅游主要是从社区发展的角度考虑旅游目的地的建设,这就必须综合考量不同利益主体之间合理的利益协调和分配机制。广州沙面有着独特的地理位置、优美的生态环境、深厚的历史文化积淀、多样而又大部保存完好的西洋近代建筑,旅游资源特色十分突出,是一处别具一格的特殊都市社区。在城市化飞速发展的今天,在都市规模急剧扩张的广州,要有效保护沙面弥足珍贵的旅游资源乃至优美环境,充分发掘其旅游潜力,就应当以社区建设与旅游开发有机结合的方式,整体调动政府、游客、旅游供应商和当地居民的积极性,构建和谐的利益相关者关系网,尤其是通过居民参与来提升他们对地方特色旅游资源的正确认识和保护观念,这对居民或资源本身及其他旅游利益相关方都能起到积极的作用。
