上海港在“21世纪海上丝绸之路”的地位及发展战略研究

基于1995、2005、2015年的中国国际航运数据,运用枢纽度模型与复杂网络方法重点分析了上海港在“21世纪海上丝绸之路”沿线的港口地位变化,结果表明：上海港成为“21世纪海上丝绸之路”沿线最重要的港口,联系航线比重上升,范围扩大,强度增强,与东南亚的港口联系最为紧密;中国面向“21世纪海上丝绸之路”沿线航运网络由香港、上海（一主一副）的双中心向上海、宁波、深圳、香港的四中心发展,上海港成为四中心港口之首,上海港和宁波港同质竞争激烈;最后,从港口层面、区域层面、国家层面的角度提出上海港在“21世纪海上丝绸之路”中的发展建议,包括东南亚发展战略、港口协同发展战略、金字塔发展战略。     

Scars of Parturition? Influences Beyond Parity

In the 40 years since the phrase ‘scars of parturition’ was coined, studies have attempted to show the relationship between scars on the bony pelvis and parity history. Despite numerous studies, the relationship of parity and scarring remains unclear. The challenge facing these studies is the rarity of skeletal collections of known parity. The alternative study approach is examining relationships between scars and factors other than pregnancy‐related strains that may affect their manifestation. Skeletal remains of 312 individuals were examined for scarring at the dorsal pubic surface, pubic tubercle, preauricular sulcus, interosseous groove and iliac tuberosity. Pelvic and femoral measurements were also taken. Features were compared according to sex and age. Principal components analysis was performed to assess the influence of body and pelvic size on scar manifestation. Scars occurred in both sexes, although they were more common and more severe in females. Scar severity remained unchanged or increased with age in both sexes. Females had smaller bodies but larger pelves than males. The interspinous and transverse inlet diameters and the femur measurements increased with age. Principal components analysis showed that body and pelvic sizes represented the majority of the observed variation, with scars occurring more commonly in small‐bodied individuals with large pelves, most of which were females. Both sexes also show a difference in the magnitude of scarring at the pubis and ilium. These results suggest that weight‐bearing and pelvic stability may be a better explanation for scarring than parturition‐related strain. Female pelves are more flexible and require more ligamentous stabilization, causing increased scar formation. The weight‐bearing strain on male pelves may sometimes also be sufficiently large to cause similar scars. Future studies may be able to test this theory on samples of known parity history.

‘I feel like this is a good place to be’: children's experiences at a community recreation centre for children living with low socioeconomic status

The purpose of this qualitative case study was to explore the experiences of children living with low socioeconomic status (SES) at a community recreation centre using the framework of place attachment [Scannell, L., and R. Gifford. 2010. “Defining Place Attachment: A Tripartite Organizing Framework.” Journal of Environmental Psychology 30 (1): 1–10. doi:10.1016/j.jenvp.2009.09.006]. Seven children took part in semi-structured interviews and drawing activities. Additional data were collected through observations, field and reflective notes, documents and a staff focus group interview. The overarching theme of having opportunities emerged from a thematic analysis of the data. The children, as they shared about their experiences at the centre, talked about having opportunities in three main ways: opportunities to do, opportunities to connect and opportunities to be. The findings are discussed broadly within the framework of place attachment and through the literature on after-school programming, children's geographies, place and SES.     

改革开放以来宋史研究若干热点问题述评

改革开放以来,宋史研究取得长足进步,这不仅表现为典章制度史、财政问题与部门经济史、城市史、人口史、货币史、区域经济史、法制史、社会史、家族史、妇女婚姻、文化思想等领域都有颇见功力的专著问世,而且对诸多热点问题,如历史分期与宋代的历史地位、积贫积弱、宋代经济发展水平、南宋历史地位、皇帝与士大夫共治天下、宋太祖不杀大臣、相权消长、士风、士人转型与唐宋变革以及王安石变法等都有广泛而深入的讨论,大大推进了对宋代在中国历史上的地位及其特点的认识。思想解放、研究方法和倾向的多样化、宋代文献的整理和出版均对宋史研究的进步产生了巨大的推动作用。但研究中也存在不讲求学术规范、重复研究、短期速成等缺陷。     

美国第三次三K党运动兴起原因探析

美国第三次三K党运动始于二战结束,持续至今。第三次三K党运动是美国社会文化传统、特定社会环境和特殊政治机制的产物,它的兴起和长期存在有其必然性。南部同盟传统、暴力传统、言论自由与结社传统是三K党长期存在与发展的历史原因;美国部分白人经济地位的困窘成为该运动的经济根源;美国种族政策的变迁与极端宗教信仰的出现为该运动提供了种族信条与宗教信仰的错误指导;美国行政制度的不力为该运动觅得繁衍的空间。     

Disability and Active Life Expectancy Among Older Cambodians

Older adults in Cambodia are survivors of harsh living conditions, including poverty and periods of extreme violence. Although these experiences may affect health outcomes, little data has existed to monitor Cambodia's older population. The current paper uses data from the 2004 Study of the Elderly in Cambodia (SEC) and focuses on disability status. The data is the first of its kind for Cambodia—a comprehensive survey employing a representative sample of adults 60 and older living across the country. Disability prevalence by age and sex, Active Life Expectancy (ALE) and common correlates of disability, using Activity of Daily Living (ADL) items, are examined. In addition, disability prevalence rates are compared to those for older adults living in other countries in South-east Asia. The results indicate that older Cambodians are more disabled than their counterparts living elsewhere. Possible reasons include long-term influence of social disruption and poverty. Women live longer than men, but spend a greater proportion of their remaining life in states of disability and severe disability. Correlates of disability show that younger age, being male, having higher income satisfaction, being married and living in urban areas associate with lower probabilities of reporting disability. A contribution of the analysis is the examination of a basic measure of health among a population of which little is known.
