Physical and social barriers to social relationships: voices of rural disabled women in the USA

Through exploring the lived experiences of disabled women, this study investigates how physical and social barriers affect their social relationships. In‐depth tape‐recorded interviews investigating a variety of social and interpersonal issues were conducted with 24 women with physical or visual impairments who lived in a rural region of the midwestern USA. Using content analysis, the researchers examined interview data for common themes and patterns relating to social relationships. The findings indicate that physical barriers, related to the physical environment and personal physicality, along with social barriers, involving preconceptions of others about impairment and restrictions in personal networks, hamper the initiation and maintenance of social relationships. Further, the experiences of this group of disabled women corresponded most closely with the premises of a social relational understanding of disability.     

阶级分析的三种逻辑与中产阶级研究

本文着重探讨阶级分析的不同传统所强调的三类因果过程:首先是对个体生活有着显著影响的不平等的生活条件相关联的机制;其次是与各种社会封闭形式(forms of socialclosure)有关的机制,社会封闭使得某些个人或群体通过排斥他人而享有获取资源和机会的优势;第三是与个人或群体通过控制他人活动而受益的方式有关的机制。这三类机制可分别称作:基于个人属性和生活条件的阶级划分机制、基于机会阻隔(opportunity-hoarding)的阶级划分机制和基于支配、剥削关系的阶级划分机制。对于中产阶级的分析可以联系上述三种机制进行理解:中产阶级在不平等的生活条件分布中占据中间位置;他们受益于劳动力市场中的机会阻隔,特别是通过技能认证和资格审查制度得以实现;他们在支配和剥削他人劳动的同时自身又受到支配和剥削。     

Assessing the impact of ICH E9

The ICH harmonized tripartite guideline 'Statistical Principles for Clinical Trials', more commonly referred to as ICH E9, was adopted by the regulatory bodies of the European Union, Japan and the USA in 1998. This document united related guidance documents on statistical methodology from each of the three ICH regions, and meant that for the first time clear consistent guidance on statistical principles was available to those conducting and reviewing clinical trials. At the 10th anniversary of the guideline's adoption, this paper discusses the influence of ICH E9 by presenting a perspective on how approaches to some aspects of clinical trial design, conduct and analysis have changed in that time in the context of regulatory submissions in the European Union.     

Generosity vs. Altruism: Philanthropy and Charity in the United States and United Kingdom

This paper presents a comparative analysis of giving ethos and behavior in the United States and the United Kingdom, in particular the relationship of giving to civic life. Obvious disparities between the two countries exist when overall levels of giving are considered. In the United States, individual giving as a percentage of gross national or domestic product has consistently hovered around 2% of Gross Domestic Product. By contrast, charitable giving in the United Kingdom has yet to reach 1% of GDP. The paper identifies the differences in giving ethos and behavior in the two countries in relation to the complexity of the differences between the political structures, social attitudes, and the role of charitable giving in the two countries. In particular, the paper postulates a set of models—generosity and altruism—for explaining the differences.     

Residence and Income Inequality: Effects on Mortality Among U.S. Counties

Abstract Despite lower average incomes, greater percentages living in poverty, lower levels of health insurance, less preventive health care, and poorer health status, nonmetropolitan residents have been found to experience lower mortality than their metropolitan counterparts. Several pathways through which residence influences mortality have been proposed. The objective of this study is to examine the effects of income inequality on residential differentials in mortality. Using data from the Compressed Mortality File for counties in the coterminous United States for 1990, we estimate weighted least squares models of total mortality for 3,067 counties, and separately for metropolitan and nonmetropolitan counties. Mortality is lower in nonmetropolitan counties than in metropolitan counties, once rates are standardized for age, sex, and race. Moreover, income inequality exerts stronger effects in nonmetro counties, an effect that persists when per capita income, median household size, and racial composition are controlled. The percentage of the population that is black exerts an independent effect on mortality in both metro and non‐metro counties.     

The specification of personalised insoles using additive manufacturing

Research has been conducted to explore a process that delivers insoles for personalised footwear for the high street using additive manufacturing (AM) and to evaluate the use of such insoles in terms of discomfort. Therefore, the footwear personalisation process was first identified: (1) foot capture; (2) anthropometric measurements; (3) insole design; and (4) additive manufacturing. In order to explore and evaluate this process, recreational runners were recruited. They had both feet scanned and 15 anthropometric measurements taken. Personalised insoles were designed from the scans and manufactured using AM. Participants were fitted with footwear under two experimental conditions: personalised and control, which were compared in terms of discomfort. The mean ratings for discomfort variables were generally low for both conditions and no significant differences were detected between conditions. In general, the personalisation process showed promise in terms of the scan data, although the foot capture position may not be considered 'gold standard'. Polyamide, the material used for the insoles, demonstrated positive attributes: visual inspection revealed no signs of breaking. The footwear personalisation process described and explored in this study shows potential and can be considered a good starting point for designer and researchers.     

A time series of urban forestry in Los Angeles

There has been an increasing interest in the evolution of urban forests. This research uses historic and digital aerial photography to quantify changes in tree density in Los Angeles, California since the 1920’s. High-resolution geographic information system analysis (4 to 6 time periods) of three regions (San Fernando Valley, Hollywood, Los Angeles Basin) of Los Angeles reveals that there has not always been an increase in tree density with time. Tree densities on public and private land were highest in the 1940’s in Hollywood, while the San Fernando Valley and Los Angeles Basin experienced a near linear increase in tree density on both private and public land since the 1920’s. When historic tree density reconstructions were examined for the 15 Los Angeles city council districts from the 1920’s, 1950’s and 2006, most districts in Los Angeles have experienced a significant increase in tree density, however, there has been wide variation in tree densities among city council districts. Trees densities have generally been higher on private land since the 1920’s and currently tree densities on private land are significantly higher than on public land. Results suggest the evolution of urban forests in Los Angeles mirrors the dynamics of urban forests in desert and grassland cities. It is possible to reconstruct the development of urban forests in sections of cities using historic and contemporary aerial photography. We estimated that Los Angeles averages approximately 104 trees per hectare (82 private land, 22 public land) based on 2006 imagery at 0.3 m resolution, however, field validation suggests that we identified only 73% of trees. Although there is still space to plant trees on public land, private land owners will need to be heavily involved in order to achieve the goals of Los Angeles’ Million Tree Initiative.
