A mixed-methods investigation of successful aging among older women engaged in sports-based versus exercise-based leisure time physical activities

This mixed-methods study compares active older women in different physically based leisure activities and explores the difference in subjective ratings of successful aging and quantifiable predictors of success. A survey was administered to 256 women, 60–92 years of age, engaged in a sports- or exercise-based activity. Quantitative data were analyzed through ANOVA and multiple regression. Qualitative data (n = 79) was analyzed using the approach associated with means-end theory. While participants quantitatively appeared similar in terms of successful aging, qualitative interviews revealed differences in activity motivation. Women involved in sports highlighted social/psychological benefits, while those involved in exercise-based activities stressed fitness outcomes.     

Non‐governmental organisations and informal associations in service delivery for African migrants in China: Evidence of voluntary sector failure?

As the Chinese government has purposefully built economic, social and political links with several African states in recent decades, new patterns of international migration have emerged. Notably, mixed‐race families are increasingly visible in southern China, particularly Guangzhou, where there is a concentration of African traders. The few existing studies on this population have failed to pay attention to how, in the absence of state provision of or support for key public resources including health care and education, African‐Chinese families are raising their children. We examined factors contributing to NGO successes and failures in facilitating these families’ wellbeing and integration into mainstream society, drawing on the theory of voluntary sector failure. Mixed‐raced families are relatively isolated from mainstream society as well as formal/informal civil society organisations. We found select features of philanthropic paternalism, philanthropic amateurism, and what we term philanthropic mistrust, with implications for understanding voluntary sector growth in the Chinese context.     

Top United Nations Peacebuilders and Advocacy for Women, Peace, and Security

A strong correlation between the sex of United Nations (UN)peace operation managers and their advocacy for the role ofwomen in peacebuilding was found in an internet study carriedout in May 2008. Senior female UN managers involved in peaceprocesses are ten times more likely than male colleagues publiclyto address women's roles as peacebuilders, yet of the sixty-sixSpecial Representatives of the UN Secretary-General (SRSG),Deputy Special Representatives of the UN Secretary-General (DSRSG),and Special Envoys addressing peacebuilding who were listedon the Department of Peacekeeping Operations (DPKO) web sitein May 2008, only six were women. In view of the large numbersof women who become refugees or are internally displaced dueto armed conflict, it is paramount that peace processes includethem at all levels and in all aspects on an equal footing withmen. Appointing more women to senior level positions in theUN is one way to achieve this aim.     

基于奇异值分解去势的非线性趋势序列单位根检验研究

 如何克服ADF与PP单位根检验法对非线性趋势平稳序列的伪检验,提高单位根检验的功效,是非平稳时间序列分析的重要问题。本文基于奇异值分解的思路,构造出检验非平稳时间序列单位根的SVD-RMA检验法,此方法将时间序列的趋势项与干扰项分离,然后用递归均值调整法对干扰项进行检验。仿真实验表明,SVD-RMA法对线性与非线性趋势、甚至结构突变过程的检验功效都非常好;对非线性趋势平稳的检验而言,SVD-RMA检验得到正确结论的可能性要远远好于ADF与PP检验。     

Stimulus-Stimulus Pairing of Vocalizations: A Systematic Replication

The current study replicated an enhanced stimulus-stimulus pairing (SSP) procedure used by Esch et al. (Journal of Applied Behavior Analysis 42: 42–225, 2009) for increasing vocalizations in children with autism. The enhanced SSP procedure consisted of pairing target vocalizations with high-preference items, interspersed target and nontarget trials, an observing response, and the presentation of the vocalizations in “motherese” speech. Results showed substantial increases in target vocalizations above baseline levels and above nontarget vocalizations for two of three participants.     

What's in a Name? Causes and Consequences of Labelling Minorities as “National” or “Migrant”: Roma in Italy and Spain

This article analyses how Roma are represented in official policy narratives in Italy and Spain by comparing the four cycles of the Framework Convention for the Protection of National Minorities in the two countries. By tracing the representations that the Italian and Spanish governments hold (and make) about the Roma, I sketch out the different categories that EU‐ropean countries recur to as organizing principles to “other” underprivileged minorities. Based on the tailored‐approaches in which both Italy and Spain engage in framing Roma as either a “national” minority or not, I suggest that constructing or “producing” a minority in our imagined communities as characterized by national, cultural, social or migrant characteristics relies more on political expediency than on objective analytical categories.     

A Comparative Analysis of the Relative Effectiveness of Four Dynamic Lot-Sizing Techniques on Return on Investment

The relative performance of dynamic lot-sizing techniques has been of considerable interest to researchers in recent years. While research has addressed performance in terms of cost-effectiveness, researchers have not determined the impact of dynamic lot-sizing techniques on return on investment (ROI) as it applies to finished goods' schedules. The purpose of this research is to explore the relative performance of four dynamic lot-sizing techniques with regard to ROI, namely the Wagner-Whitin, Incremental Part Period, Silver-Meal, and Groff techniques. Computer graphics are employed to analyze the relative ROI effectiveness.     

Men's psychological functioning in the context of women's breast cancer

Previous research indicates that men are affected when their female partners have breast cancer. However, little is known about what predicts men's psychological well-being in this context. The current investigation involved couples in which the woman had early stage breast cancer and explored the degree to which men's positive and negative well-being was related to women's well-being, women's physical symptoms, relationship functioning, and relationship duration. The findings indicate that all of these factors play a role and interact in predicting men's well-being. In particular, when women have a high level of physical symptoms, the typical associations between men's well-being with women's well-being and relationship adjustment no longer persist. Implications for working with couples addressing health problems are provided.
