基于模糊综合评价法的高速公路社会经济影响评价

高速公路的建设将会对沿线地区的社会经济产生影响,这些影响的大小将决定着项目的风险和成败。为了更好评价高速公路建设对沿线地区产生的社会经济影响,就需要根据现代区域经济学理论科学的确定评价内容,合理构建指标体系,正确选择高速公路建设项目社会经济影响评价方法。将模糊层次分析法应用于高速公路社会经济影响评价中,避免一些常规评价方法中的随机性和评价专家主观上的不确定性。

Role and impact of the environment on entrepreneurial learning

Abstract

This article is presenting an overview of the literature devoted to entrepreneurial learning and, more specifically, those research bringing environmental elements into the study of the entrepreneurial learning process. Then, it shows how each of the four Special Issue selected research papers contribute to enhancing our knowledge of the complexity of the learning process vis-à-vis entrepreneurial processes placed in context. By doing this, it makes an attempt to explain the specific context behind each contribution as well as presenting the wider context. Finally, the article is suggesting a set of key challenges and research pathways that might be explored in the future.

Integrated evaluation: A synthesis of approaches to the evaluation of broad-aim social programs

Integrated evaluation is intended to serve decision makers who are responsible for broad-aim social programs by providing information based on evaluation which can aid both ongoing decisions and long-term strategic decisions. It integrates elements of diverse evaluation traditions in a complementary manner: monitoring—in order to inform what has been done by the program; implementation analysis—in order to understand how decisions are being made and carried out; economic evaluation—including both cost-effectiveness and assessment of distributional effects; and goal achievement evaluation—in order to present the program outcomes from the point of view of the various parties who produced the program and/or were affected by it. The article presents these four components of integrated evaluation and discusses its advantages as well as its difficulties and pitfalls.

The impact of the European social fund on youth education and employment

The effectiveness of the European Union's Cohesion Policy in reducing regional socio-economic gaps remains an open empirical issue, while evidence as to how the policy is affected by specific territorial factors and which social groups benefit most from it remains sparse. This article seeks to address this gap by disentangling the impact of the European Social Fund (ESF) on youth education and employment prospects. Drawing on macro-level data for the European NUTS-2 regions, we assess the impact that this fund has on different education-specific youth population shares and employment rates. In the case of education, we find that the receipt of funding is associated with a human capital polarization of regional populations. Specifically, we identify a positive impact of the ESF on population shares with lower-secondary and tertiary education, and a simultaneous negative impact on the share of those with upper-secondary education. In the case of employment, we find a positive response for youth of all education levels. A heterogeneity analysis indicates that both the education and employment responses of the youth population to the receipt of the ESF are strongly influenced by local specialization in high-skilled activities.     

Assessing the social impact of charitable organizations—four alternative approaches

• There is increased societal pressure on charities to improve performance. The questions that they must ask are: (1) Who is our audience? (2) What evaluation measures are important to the organization? and (3) What evaluation measures are best for the organization? There are a number of different approaches available for assessing performance, ranging from social accounting to more informal qualitative assessments of whether the organization's mission is being achieved. This paper draws on the industry and academic discussion of evaluations of nonprofit organizations to develop a four‐category typology of alternative approaches for audiences. It then identifies the benefits and limitations of each. The goal is to identify the steps that charities should use to determine which approach is most suited to their specific circumstances. It is proposed that a collaborative development of evaluation criteria, of whichever type, may be most appropriate as will draw together the experiences and resources of multiple parties, and may have broader appeal than evaluations proposed by individual nonprofits.

Application of collective knowledge diffusion in a social network environment

ABSTRACT

We present a group dynamics model that shows knowledge integration as a process occurring over time. As each individual in the group contact others, his own knowledge changes, and over time the collective knowledge is obtained. This allows modeling knowledge diffusion in a social network and while the models presented in this paper are not competitive in that area, they approach the problem from previously unconsidered direction. We test the behavior of the model in a multi-agent simulation and we test a simple advertisement campaign in a social network. We provide discussion of elements needed for making model more competitive.
