生产者货币计价决定因素的实证研究

利用12个发达国家和发展中国家的非平衡面板样本数据,对微观、宏观和其他因素对生产者货币计价(PCP)的影响进行实证研究,指出经济规模、市场份额、金融市场的发达程度、币值的对内稳定性和产品差异化程度是最主要的影响因素,而出口商的谈判能力、币值的对外稳定性等因素也对PCP的选择有一定影响。根据实证检验结果,对人民币作为贸易计价货币的条件进行评估,发现其优势在于我国的经济规模、出口商的市场份额及其谈判能力以及人民币汇率的相对稳定性; 劣势在于相对落后的金融市场、不可预期性较大的通货膨胀水平以及产品的差异化程度。     

A grounded theory of living a life with a physical disability in Taiwan

This study explores the experiences of disability for a number of Taiwanese adults with a physical disability. Using a grounded theory approach, their experiences of living a life with a physical disability were gained through in-depth interviews. The resulting grounded theory ‘it is more than just the impaired body’ presents the dynamic interactions between the participants and the context in which they were living their lives and how they managed their lives within that context. With its inclusion of the cultural dimension, a holistic way of understanding the daily lives of those who experience physical disability in Taiwan is provided.     

Partners,Institutions and International Currencies: The International Political Foundations for the Rise of the Renminbi

The use of an international currency is not just a natural market phenomenon; it relies heavily on international political foundations. The historical lessons of the four major international currencies—the pound, dollar, euro and yen—show that a strong partner network and a favorable international institutional environment are the two major political foundations for the formation of a stable international currency. The rise of the renminbi, as a late starter looking to become a major international currency, depends not only on the requisite economic conditions but on governmental diplomacy aimed at attracting more monetary cooperation partners and creating international institutions that support its worldwide use. This strategy reinforces the political foundations for the rise of the renminbi. Building a network of partners supporting the renminbi as an international currency and creating a system of international monetary institutions are the real tests of the issuing country’s political leadership. This political leadership capacity has three dimensions: public trust founded on reputation building; a centripetal force driven by provision of benefits; and coercive force applied through sanctions. Comparatively speaking, the renminbi is still in the early stage of its ascent, so the development of its political infrastructure should concentrate mainly on gaining public trust through reputation-building and employing centripetal force involving provision of benefits.     

Physical exercise,nutrition and hormones: three pillars to fight sarcopenia

Background: Sarcopenia is a pathophysiological condition diffused in elderly people; it represents a social issue due to the longer life expectancy and the growing aging population. It affects negatively quality of life and it represents a risk factor for other pathologies, such as diabetes, cardiovascular disease, and obesity. No silver bullet exists to hinder sarcopenia, but it may be counteracted by physical exercise, nutrition, and a proper endocrine milieu. Indeed, we aim to analyze the scientific literature to give to clinician effective advices to counteract sarcopenia.

Main text: Physical exercise, proper nutrition, optimized hormonal homeostasis represent the three pillars to fight sarcopenia. Physical exercise represents the most effective remedy to face sarcopenia, in particular if it is combined with a proper diet and with an adequate endocrine milieu. Consistency in training, adequate daily protein intake and eugonadism seems to be the keys to fight sarcopenia. The combination of these three pillars might act synergistically.

Conclusions: Optimization of these factors may increase their efficiency; however, scientific data may be sometimes confusing so far. Therefore, we aim to give practical advices to clinician to identify and to highlight the most important aspects in each of these three factors that should be addressed.

Evidence-Based Programs for Older Adults: A Disconnect Between U.S. National Strategy and Local Senior Center Implementation

While U.S. national policies have been developed to support evidence-based (EB) lifestyle programs for older adults, there has been limited research to determine the extent to which these programs actually reach local communities. This study sought to identify factors that impact the implementation of EB physical activity, nutrition, and chronic disease management programs at regional (Area Agencies on Aging [AAAs]) and community levels (senior Centers [SCs]). Interviews were conducted with directors of four AAAs and 12 SCs to understand their perspectives on EB program implementation. Narratives revealed differences between AAAs and SCs regarding knowledge about EB programs and reasons to promote and adopt these programs. The only agreement occurred when discussing concerns about funding and program inflexibility. Substantial gaps exist between how EB lifestyle programs are promoted and implemented at the regional and community levels.     

Stressors beget stressors: The effect of passive leadership on employee health through workload and work–family conflict

The current study examined passive leadership as a potential antecedent of two commonly studied workplace stressors (i.e. workload and work–family conflict), and investigated its negative effect on employee burnout and physical symptoms via these stressors. We collected two waves of data from 274 focal participants, and one wave of data from their co-workers. Results showed that both self-reported and co-worker-reported passive leadership was positively related to employee burnout and physical symptoms, as well as workload and work–family conflict. Additionally, workload and work–family conflict partially mediated the effects of passive leadership on burnout and physical symptoms, respectively. Our findings support the notion that passive leadership can create a stressful workplace and have a detrimental effect on employees’ health.
