招贴设计的方法论研究

招贴设计的方法论研究是平面设计基础理论的一个重要支系,由于招贴设计自身的复杂性,与之对应的方法论研究不应等同于一般的设计方法论.文章突破了旧有的研究体系,尝试从哲学、图像学、潜意识等多个角度去剖析创意生成的奥秘,进而引导初学者完成创意的构思.     

Application of Social Choice Theory to Modify the Value Measure of Health Systems

Social Indicators Research - As a new composite indicator for capturing the value delivered by health systems of developing and developed economies, the Value Measure is the arithmetic average of...     

Social investment effects of public education,health care,and welfare service expenditures on economic growth

The purpose of this study is to theoretically and empirically examine whether public spending in education, health care, and welfare service operates as a fruitful investment in welfare states, which has been implied in the literature of social investment arguments. Based on comprehensive review of existing literature, this study suggested a tripartite mechanism of social investment effect of such spending, that is “enhancement of human capital,” “support for labor force participation,” and “job creation.” To find the empirical evidence, a pooled time‐series cross‐section analysis was conducted with the data of 15 advanced welfare states from 1980 to 2015 using estimation technique of fixed‐effect model. The results confirmed that public spending in education, health care, and welfare service had a positive medium‐term as well as long‐term effect on economic performance, while cash‐type welfare spending had an obscure or no visible effect on economy. Government consumption that is a proxy and control variable of size of the welfare state showed a positive effect on real GDP in the medium term but a negative effect in the long run. In conclusion, this study suggests that reinforcing social services should be recognized and dealt with as essence of social investment strategy.     

大数据战略视野下我国信息网络安全立法分析

大数据战略视野下,很多国家纷纷制定、完善和执行着自己的信息网络安全法律,并已形成世界潮流.从国内外的大数据战略与信息网络安全立法分析来看,我国既有成绩,也有不足.对于我国信息网络安全的法律保障,目前需要完善的主要内容有:进一步明确国家信息网络安全立法的目的与宗旨;基本法层面,尽快构建完备的信息网络安全法律保障有机体系,重点包括政府信息公开法与个人信息保护法等;实施层面,加强与完善具体领域的单行法与配套法建设,增强法律规定的可操作性;完善法律框架之外的协作保障体系.     

感知风险对在线旅游产品购买意愿的影响分析

旅游电子商务发展迅猛,互联网购物平台的虚拟性和远程性强化了消费者感知风险,它也成为影响旅游电子商务发展的重要因素之一.文章聚焦消费者感知风险,运用SPSS 19.0及AMOS 21.0软件,构建以5个维度的感知风险为自变量、购买意愿为因变量、信任为调节变量的结构方程模型,探讨变量间相关关系.结果发现:感知风险对信任的影响差异较大,仅经济风险感知与信任呈显著负相关;感知风险对购买意愿总效应皆呈负相关;信任作为中介变量存在明显的调节作用,有效地降低了感知风险对购买意愿的负向影响.     

Bounds on the domination number of a digraph

A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of D, denoted by \(\gamma (D)\), is the minimum cardinality of a dominating set of D. The Slater number \(s\ell (D)\) is the smallest integer t such that t added to the sum of the first t terms of the non-increasing out-degree sequence of D is at least as large as the order of D. For any digraph D of order n with maximum out-degree \(\Delta ^+\), it is known that \(\gamma (D)\ge \lceil n/(\Delta ^++1)\rceil \). We show that \(\gamma (D)\ge s\ell (D)\ge \lceil n/(\Delta ^++1)\rceil \) and the difference between \(s\ell (D)\) and \(\lceil n/(\Delta ^++1)\rceil \) can be arbitrarily large. In particular, for an oriented tree T of order n with \(n_0\) vertices of out-degree 0, we show that \((n-n_0+1)/2\le s\ell (T)\le \gamma (T)\le 2s\ell (T)-1\) and moreover, each value between the lower bound \(s\ell (T)\) and the upper bound \(2s\ell (T)-1\) is attainable by \(\gamma (T)\) for some oriented trees. Further, we characterize the oriented trees T for which \(s\ell (T)=(n-n_0+1)/2\) hold and show that the difference between \(s\ell (T)\) and \((n-n_0+1)/2\) can be arbitrarily large. Some other elementary properties involving the Slater number are also presented.     

论和谐政治生态系统与政治宽容调节机制的构建

和谐政治生态突破了传统社会仅从人与人、人与社会的关系角度去理解政治的理论局限,而把政治—社会—自然三者视为三位一体的大系统,把社会更把自然纳入政治视野,运用生态学的多元思维,调整人与人、政治与社会、社会与自然的关系。这是政治价值观的一种转变。理性而客观地分析政治生态系统的本质内蕴和系统结构,并努力寻求积极的、良性运行的和谐政治生态系统和政治宽容调节机制的建构,对和谐社会的践行无疑具有重要的现实意义和理论价值。     

判断争议领土归属的法律制度

在国际司法判例的推动下,判断争议领土归属的国际法制度正逐步形成、完善.如果相关国家就争议领土的归属达成了合意或是有单方面的同意,则应当依据相关国家的意思来确定争议领土的归属.如不存在此类法律依据,则应通过综合审查各争端当事国在关键日期以前对争议领土行使主权权力的证据,依据有效占领原则确定争议领土的归属.但如依上述方法确定争议领土的归属还存在不公平、不合理的情况,则应对依法初步划定的边界进行衡平调整.     

资源型地区企业社会责任信息披露的研究

随着社会责任意识的提高,企业披露社会责任信息逐渐成为一项基本义务。本文根据深市和沪市属于资源型地区的115家上市公司2009年的财务报告及社会责任报告,分析资源型地区企业社会责任信息披露的现状,发现资源型地区上市公司披露社会责任信息存在质量不高、比例不高、缺乏可比性,且社会责任报告大多数未经过审验等问题。为解决以上问题,应采取完善社会责任信息、尽快制定有关法律法规、规范信息披露的内容和形式、加强对信息披露的的监督、扩充财务报告等措施。
