The biopsychosocial model provides the most heuristic account of the complex multifaceted nature of chronic pain and its associated impairment and disability. Although chronic pain, impairment, and disability are related, these are three separate constructs. In order to understand how these three constructs are interrelated, the development of pain from the acute to the chronic stage is discussed. Psychosocial factors as barriers to recovery are emphasized, including those that commonly manifest among patients receiving disability compensation. This is complemented by a review of psychometric instruments used to assess these psychosocial factors in chronic pain. Finally, the major delineation in levels of care for chronic pain is highlighted, emphasizing an interdisciplinary approach that is consistent with pain as a biopsychosocial phenomenon. 相似文献

An American specialist on Russian politics and federalism examines the democratizing effects, intended and unintended, of President Vladimir Putin's federative reforms. Focus is on the "harmonization" of regional constitutions and legislation with federal laws and the RF Constitution in the name of the "reintegration of Russia's legal space." On the basis of detailed analysis of changes in regional constitutions and laws ensuing from the harmonization policy, the author assesses the impact of this aspect of the reforms on democratization in Russia's regions. Regional issues examined include the separation and balance of power between the executive and legislative branches, political and civil rights, the level of demand for democratic laws and independent judicial review, and the emergence of stakeholders of these reforms within civil society. 相似文献

Despite increased attention to gender issues in the international development arena since the rise of feminism in the 1970s, few agricultural research organisations have integrated gender in their problem diagnosis and technology development. Gender mainstreaming can significantly enhance the impact of research and technology development. Entrenching gender mainstreaming in organisations and their research agendas remains a challenge. To overcome it requires political will, accountability, a change in organisational culture, and technical capacity within an organisation. This article presents an experience of gender-mainstreaming practice in the institutional culture and agricultural research processes by Urban Harvest and the International Potato Centre (CIP). 相似文献

Despite limited empirical evidence, there is growing concern that junk food availability in schools has contributed to the childhood obesity epidemic. In this paper, we estimate the effects of junk food availability on body mass index (BMI), obesity, and related outcomes among a national sample of fifth graders. Unlike previous studies, we address the endogeneity of the school food environment by controlling for children's BMI at school entry and estimating instrumental variables regressions that leverage variation in the school's grade span. Our main finding is that junk food availability does not significantly increase BMI or obesity among this fifth‐grade cohort despite the increased likelihood of in‐school junk food purchases. The results are robust to alternate measures of junk food availability including school administrator reports of sales during school hours, school administrator reports of competitive food outlets, and children's reports of junk food availability. Moreover, the absence of any effects on overall food consumption and physical activity further support the null findings for BMI and obesity. 相似文献

The global ubiquity of cloud computing may expose consumers' sensitive personal data to significant privacy and security threats. A critical challenge for the cloud computing industry is to earn consumers' trust by ensuring adequate privacy and security for sensitive consumer data. Regulating consumer privacy and security also challenges government enforcement of data protection laws that were designed with national borders in mind. From an information privacy perspective, this article analyses how well the regulatory frameworks in place in Europe and the United States help protect the privacy and security of sensitive consumer data in the cloud. It makes suggestions for regulatory reform to protect sensitive information in cloud computing environments and to remove regulatory constraints that limit the growth of this vibrant new industry. 相似文献

An innate sense of the essence of their culture sustained Afghans through 24 years of conflict and displacement. Although they continue to cherish the diversity of regional differences, individuals cling tenaciously to their national identity, upholding traditional values and customs that distinguish them from their neighbours. From the beginning of the twentieth century, attempts to foster unity through nation-building activities in mostly urban areas met with mixed success; the latest attempts to cast Afghans in a puritanical Islamic mould met with disaster. Years of discord stretched taut the fabric of the society and national traits once honoured hallmarks of the culture were compromised. Yet the fundamentals of the culture remain strong, changed in some ways but readily recognisable as uniquely Afghan. Current expectations aim to engage various cultural elements as bonding vehicles to hasten reconstruction and strengthen peace. 相似文献
