社科学术期刊“双赢”取向中的现状与困惑

如何实现社科学术期刊社会效益与经济效益“双赢”,这是社科学术界、期刊界多年来谈论不休、意见不一的问题,也是许多业内人士不愿意面对且令人头疼的问题。在经历了十余年的研究和争论后,当下有必要对这场讨论作一番简要的疏理。

我国警察机构及警察权改革刍议

对暴力使用权的合法垄断是国家权力的本质特征,国家对暴力的垄断集中体现在军队和警察身上,警察的暴力垄断使用权是其对内政治表达和稳定秩序的需要。目前。我国的警察权设置过于狭隘,已不能满足社会和民众的需要。调整现在的警察机构设置和警察权的设定,成为我国行政体制改革、建设服务型政府的当务之急,也是我国警察体制改革的必由之路。同时,只有采用新的工作原则和制度安排,才能使分散化的警察机构设置产生更大的效用,发挥机构分散化带来的优势,克服分散化带来的劣势,推进警察和社会安全体系的建设。     

模拟研究非偏振入射KIO3晶体粉末倍频效应

根据Kurtz粉末倍频理论,采用实验室设计搭建的测试装置,通过研究分析颗粒尺寸在范围46μm~250μm的双轴KIO3晶体粉末透射倍频光的相位匹配特性,建立了大的双折射双轴晶体粉末的倍频效率模型.通过这一模型可模拟出双轴晶体的倍频系数.结果表明,KIO3晶体粉末透射倍频光具有相位匹配特性,这与相关文献报道的结果相一致.数值模拟得到的KIO3晶体粉末的倍频系数与已报道的KIO3晶体的倍频系数相吻合.由此可见,我们所建立的模型是可行的,能够用于双轴晶体粉末倍频效应的研究.同时,我们在模拟研究中发现KIO3晶体属于第II类相位匹配类型.     

曾国藩对后世深远影响之论析

曾国藩为政上被誉为“成同中兴第一臣”,为文上被称为“桐城古文的中兴大将”。曾氏去世后,清廷以国葬之礼厚待,当朝权贵文士撰文盛赞其不朽功业。清末反满革命浪潮迭起,曾氏受到革命党人斥责在所难免,但文学成就仍受后人称颂,再传弟子林纾光复湘乡文派。曾国藩的丰功伟业在一定程度上激发毛泽东救国救民伟大抱负,蒋介石也以之为效法榜样来治理国家。     

我国外商投资结构分析

改革开放是实现我国社会主义现代化的必由之路,吸收和利用外资是加快现代化建设的重要条件。为适应经济全球背景下发展开放型经济的需要,解决外商在我国投资地域结构不平衡和产业结构不合理的问题,应配合国家新的产业结构调整战略的实施,进一步提高吸收外资的水平,积极、合理、有效地利用外资,改善外商投资的地域结构和产业结构。     

中国十大城市群城镇化水平与城市脆弱性的脱钩关系研究

文章基于中国十大城市群内100个地级以上城市的相关数据,通过构建城镇化水平与城市脆弱性综合评价指标体系,采用因子分析法和Tapio脱钧指数法,实证研究了中国十大城市群及所属城市的城镇化水平与城市脆弱性的脱钩关系,并对其脱钩状态进行判别和分析比较.结果表明:京津翼城市群城镇化水平与城市脆弱性的脱钩状态最理想,辽中南城市群、长三角城市群、山东半岛城市群和川渝城市群均为相对理想的脱钩状态,其他城市群的脱钩状况均不容乐观;在17个中心城市中,仅有洛阳、深圳、成都和西安4个城市的城镇化水平与城市脆弱性的脱钩状态相对乐观,经济发展水平较高的北京、上海和广州3大城市的脱钩状态均不理想.     

Correlates of Depressive Symptoms among Homebound and Semi-Homebound Older Adults

ABSTRACT

This study aimed to provide a national profile of homebound and semi-homebound older adults with depressive symptoms and to compare risk factors of depressive symptoms by homebound status. A sample of 1,885 homebound and semi-homebound older adults was selected from Round 1 of the National Health and Aging Trends Study (NHATS). The prevalence of depressive symptoms was 43.9% in homebound older adults and 28.1% in semi-homebound older adults, representing over 830,000 and 1.4 million individuals in the population, respectively. Nearly two-thirds of homebound and over half of semi-homebound older adults with clinically significant depressive symptoms also had significant anxiety symptoms. Results from logistic regression showed that younger age, certain medical morbidities, severity of functional limitations, and pain were common risk factors for depressive symptoms among homebound and semi-homebound older adults. Some differences in the risk factor profile emerged between the homebound and the semi-homebound populations. Alleviating the burden of depression in the semi-homebound population may focus on early prevention that considers the diversity of this population. Home-based, integrated programs of health and mental health services that simultaneously address the medical, psychiatric, and neurologic comorbidities and disabilities of homebound older adults are needed to meet the complex needs of this population.     

欲望、资本与精神分裂——论系列电影《小时代》的时代隐喻

系列电影 《小时代》 继承了海派文学书写现代性体验的传统,然而却展现出消费时代一个消弭了历史与地理意义的闭合欲望空间.资本是 《小时代》 中个体生活样态内在的运行逻辑,也是外在的魅力源泉,并实现了对于个体精神的影响与规训.在资本追求感性快乐与引发物质差异的双重作用中,《小时代》 反映出主体精神分裂的时代症候,并由此成为关于分裂的寓言式呈现.     

Parameter estimation of a composite production function model based on improved artificial fish swarm algorithm and model application

The traditional Cobb–Douglas production function uses the compact mathematical form to describe the relationship between the production results and production factors in the production technology process. However, in macro-economic production, multi-structured production exists universally. In order to better demonstrate such input–output relation, a composite production function model is proposed in this article. In aspect of model parameter estimation, artificial fish swarm algorithm is applied. The algorithm has satisfactory performance in overcoming local extreme value and acquiring global extreme value. Moreover, realization of the algorithm does not need the gradient value of the objective function. For this reason, it is adaptive to searching space. Through the improved artificial fish swarm algorithm, convergence rate and precision are both considerably improved. In aspect of model application, the composite production function model is mainly used to calculate economic growth factor contribution rate. In this article, a relatively more accurate calculating method is proposed. In the end, empirical analysis on economic growth contribution rate of China is implemented.
