文学的真实性新探

传统的文艺学认为文学的真实性就是指文学作品通过艺术形象反映社会生活所达到的准确程度。尽管这一观点似乎已成为文艺理论工作者的共识并被写入全国高校汉语言文学专业的教学大纲 ,但笔者仍然认为这一提法很值得商榷。在对文学的本质属性进行重新的审视之后 ,我们认为关于文学的真实性应该作这样的解释 :它是指作家经过对一定的社会生活现象或假定的生活现象进行艺术概括而创造出来的具体生动的艺术形象 ,从而表现出人性的特征或内容 ,展示出社会生活的本质规律以及人生理想等。它是现象与本质、真相与假象、合情与合理的统一。     

四川省区域经济增长趋同与分异研究

根据1978--2005年四川省各市州的人均GDP数据,以新古典增长理论为基础,对四川区域经济增长进行研究。结果表明：在整个时段上,四川区域经济增长经历了趋同一分异一趋同的过程;在1978--1990年期间,区域经济增长存在显著趋同且趋同速度较快,但在1990--2005年期间,区域经济增长分异的趋势较强。趋同的趋势不甚明显;通过引入控制变量和地区虚拟变量分析,说明在社会主义市场经济体制建立的过程中。四川区域经济增长存在条件收敛,五大经济区有“俱乐部”趋同的倾向。     

A longitudinal comparative study of the impact of the experience of social work education on interpersonal and critical thinking capabilities

Head (the intellectual/critical thinking) and Heart (the emotional-interpersonal) are long established twin-pillars of social work. Their importance is not just reflected in literature devoted to each but in the professional proficiencies and capabilities expected for practice. While clearly intertwined—both operate together in practice—and central to practice proficiencies/capabilities, implying implicit measurement of standards, there is a curious lack of research focusing on measurement of the two together. This novel study is the first to carry out a longitudinal comparative study examining the extent to which interpersonal and critical thinking capabilities are developed during the lifetime of qualifying social work training as measured through programme performance and development. It focuses on four cohorts (n = 170) at two Universities (Undergraduate and Masters). While findings show the interpersonal significantly underpinned performance and outcome, critical thinking—though embedded in Masters programme performance—was less significant, particularly in the undergraduate programmes. The study concludes that we cannot assume interpersonal and critical thinking capabilities are always incorporated into the learning process and attention should be paid to the overt measurement of interpersonal and critical thinking capabilities together with the processes and mechanisms by which they are focused on in programmes.     

The Culture of High-Risk Alcohol Use Among Club and Intramural Athletes

Abstract

Objective: The purpose of this study was to examine the drinking patterns of club and intramural college athletes and compare their alcohol consumption, perceived norms around the excessive use of alcohol, experience of negative consequences, and employment of protective strategies with those of campus varsity athletes. Participants: A total of 442 undergraduate students attending a private, suburban institution in the Northeast participated in the American College Health Association National College Health Assessment-II Web survey in spring 2011. Thirty-five students identified themselves as varsity athletes, 76 identified as club sport athletes, and 196 students identified themselves as intramural athletes. Methods: Survey responses were analyzed using Statistical Package for the Social Sciences. The Pearson's correlation coefficient and test for independence were applied to identify significant relationships between athlete status and identified variables related to alcohol use. Results: Results indicated that there were significant correlations between athlete status and all variables, to varying degrees. Conclusions: These findings have implications for campus health promotion professionals and athletics program coordinators seeking to address high-risk alcohol use among college athletes.     

基于潜类别随机前沿的区域创新效率及其影响因素分析

运用可根据研究对象的潜在属性内生分组的潜类别随机前沿模型,采用1999-2012年中国各省区数据,研究各省区的创新效率及影响因素。结果表明:以人力资本水平和基础设施状况为条件变量,将全国各省区分成两个技术类别,分别有各自的技术前沿和函数形式,A类别中上海市的创新效率最高,B类别中河北省的创新效率最高;平均来看,各类的创新效率均呈上升趋势,贸易开放、产业结构和金融发展对创新效率均有显著的正向作用,同时创新效率在各类内部均存在俱乐部收敛。     

Optimal training plans on physical performance considering supercompensation

Abstract

A quantitative evaluation of athletic training is one of the most important issues in the sports science, and its optimization problem between fitness and fatigue has to be considered. Although fitness is the gain of athletic training and athletes can acquire extensive fitness by hard training, they cannot continue such training for a long time because of fatigue. After the hard training which exceeds the physical capacity of athletes, a delayed onset muscle soreness (DOMS) appears and they cannot continue the same training hereafter. Because DOMS impedes the progress of training, it must be avoided when the training plan is made. By continuing training for a long period, the performance capacity of athlete body has enhanced and they can endure hard and long training with which it could not tolerate before, and such performance capacity enhancement is called supercompensation. In a planning athletic training, its optimization problem between fitness and fatigue should be discussed considering, both DOMS and supercompensation by forming probabilistic models of fitness and fatigue, optimal training plans which maximize the total fitness during training periods and minimize the occurrence of DOMS are discussed analytically and numerically.

中国城市资本回报率的“俱乐部收敛”现象及其原因

将关于中国区域资本回报率的研究从省级层面拓展到地级市层面,有助于厘清中国区域发展的“南北分化”“一市独大”等问题。通过对321个地级以上城市2000—2018年数据的实证研究,发现城市间的资本回报率差距总体在扩大,但其中也出现了一些“俱乐部收敛”现象：从城市等级看,直辖市、副省级城市、省会城市、地级市分别出现了俱乐部收敛;从城市群看,京津冀、长三角、成渝、长江中游、中原、呼包鄂榆、兰西城市群各自出现了俱乐部收敛。进一步研究发现,资本有机构成的趋同是这些城市群体资本回报率收敛的一个重要原因。这意味着,在促进资源要素向资本回报率更高的中心城市、城市群集聚的同时,加强区域内、区域间科技合作,实现技术进步速度在更大范围内趋同,是改善中国整体资本回报率的关键。
