Frontiers of Business Research in China 2017年第2期11卷 167-185页

A twenty-year study of the Human Resource （HR） practices- outcome relationship has found that more rigorous methodologies have been adopted over time. However, several problematic features such as cross-sectionaL single-informant, and single-level designs continue to be adopted （Bainbridge et al., Human Resource Management, 2016）. Responding to calls for increased contextualization of research by investigating the relationship between the location of data collection and the methodological choices of researchers, this study answers the question ＂How unique are the methodological choices of HR research conducted in Asia？＂ Applying content analysis to 241 published articles, we compare internal, external, construct and statistical conclusion validity of studies collected in North America （n^66）, Europe （n=95） and Asia （n=80, including 57 studies from China）. Results show that despite similarities in cross-sectional, single-informant and single-level designs across regions, research conducted in Asia is mainly undertaken via field studies, using subjective outcome measures at the organizational level, following a post-predictive design. In addition, studies from Asia are more recent, and show a shorter time gap between data collection and publication. Theoretical and practical implications embedded in the dynamic context of Asia in general, and China more specifically are discussed.

Mobile ad-hoc communication is a demonstrated solution to mitigate the impact of infrastructure failures during large-scale disasters. A very complex issue in this domain is the design validation of software applications that support decision-making and communication during natural disasters. Such disasters are irreproducible, highly unpredictable, and impossible to scale down, and thus extensive assessments cannot be led in situ. In this context, simulation constitutes the best approach towards the testing of software solutions for natural disaster responses. The present survey reviews mobility models, ad-hoc network architectures, routing protocols and network simulators. Our aim is to provide guidelines for software developers with regards to the performance evaluation of their applications by means of simulation.

目的：为了解中国和赞比亚消费者在多大程度上理解和使用营养标示栏,并评价选择食物时使用营养标示栏(NFP)的影响因素水平。方法：分别从南京和利文斯敦的两个国际都市募集498名中国消费者和325名赞比亚消费者。使用购物中心现场采访调查技术,在中国的主要食品超市如麦德龙、沃尔玛、苏果,在赞比亚的斯帕尔、绍普莱特附近对消费者进行方便的抽样,并使用结构式问卷进行调查。选择18岁及以上的参与者。性别、年龄、教育程度、职业、收入、家庭人数和健康状况是自变量,消费者阅读和理解NFP是应变量。数据统计参用卡方检验法分析研究结果。结果：记录了中国(58.7%)和赞比亚(67.1%)消费者意识并阅读NFP信息的平均水平。此外,卡方检验揭示基于性别的统计学差异。在两个地区更多女性(中国65.3%,赞比亚74.4%)消费者都比男性消费者(中国51.1%,赞比亚60.9%)在使用NFP上意识性更强。使用NFP的消费者大多是中年人(31-45岁和46-50岁)。并且中等及以上教育水平的消费者对NFP有更高的意识和理解水平。在中国和赞比亚,当消费者属于医学领域、工程师、商人、教师和家庭主妇,则会更多地使用NFP。调查结果显示两地家庭对NFP知晓度产生的影响具有显著性差异。在中国的家庭比赞比亚的家庭更有意识使用NFP。至于收入,在中国那些高收入的消费者比低收入使用NFP更多,而在赞比亚所有收入水平使用度平均分布。健康状况代表个人或任何一名家庭成员当前的健康状况,在中国,健康状况这一变量在意识和阅读NFP上有积极影响,存在健康问题的消费者(72.6%)比那些没有健康问题的消费者会更多的使用NFP。由于结果没有统计学意义,这种情况在赞比亚并非如此。结论：NFP的知晓度和使用存在的多样性主要是由于个人特征的影响。这些个人特征可能促进消费者使用NFP(如受过更高教育的个体意识并使用NFP的可能性更高),或对消费者产生负面影响(较低或未受教育的消费者不太可能意识到使用NFP)。性别、教育和职业对中国和赞比亚的消费者都具有积极影响。收入水平和家庭人数对中国消费者具有积极的影响,但赞比亚的消费者无此效应。健康状况也积极影响着中国消费者使用NFP,而赞比亚消费者却不是这样。结果表明,需要发展项目旨在提高NFP信息的意识水平,以确保发展健康的消费习惯。特别是那些不知道并混淆NFP成分表,在意食品标签的其他组分而忽略了NFP的高比例的消费者。这也将确保消费者明智选择食物,避免饮食相关的疾病。

Introduction: Early surgical treatment (within 48 hours) has been recommended for femoral neck fractures in order to avoid complications and reduce mortality rate, regardless of presence and severity of comorbidity and preoperative status (ASA score). However some studies evidenced that early surgery doesn’t always have a beneficial effect on mortality and complications. Therefore further studies could be useful in order to better assess risk related factors of patients requiring surgical treatment for femoral neck fracture. The purpose of this study is to evaluate the effect of preoperative ASA score and timing of surgery on mortality, complications and clinical outcome. Methods: All 336 patients operated in our center from January 2013 to december 2014 were selected for this retrospective study. Patients were divided in three groups as follows: group 1 patients treated within 48 hours;group 2 patients treated between 48 to 96 hours;group 3 patients treated over 96 hours. The preoperative ASA score was recorded for each patient. Complication, clinical outcome and mortality at one-year follow-up were evaluated. At follow-up ambulation was graded as: confined to bed, assisted ambulation, and normal ambulation. Complications both local (infections, malunion, dislocation) and systemic (deep vein thrombosis, pulmonary embolism, lung infections, ischemic disorders of heart) were recorded as well as number of transfusions. Statistical analysis was performed with chi square test and P value Results: 308 patients’ data were fully available for this study. At one-year follow-up return to normal ambulation was higher for patients of group 1 as compared with group 2 and 3 and in group 2 as compared with group 3 (P = 0.04). There was no difference in mortality and return to ambulation between patients with ASA score 1 and 2 (P = 0.06);patients with ASA score ≥ 3 showed a statistically significant higher mortality (P = 0.004) and rate of complications (0.0008) regardless of timi

This paper describes the theses that constitute the Theory of Dynamic In-teractions. It is the scientific legacy of its promoter, Dr. Barceló who, after more than forty years developing this research project, has published his first book in the English language: New Paradigm in Physics. This book, as well as the bibliography and videos on this dynamic theory, is described in this article, which analyzes the behavior of rigid bodies subjected to accelerations by rotational movements, contributing new hypotheses of dynamic behavior.
