In the higher educational setting, students provide a relevant contribution to the quality of educational services. In such a context, the measurement of the perceived quality and related satisfaction for the university experience are of primary interest to evaluate the efficiency and efficacy of the learning processes. In this contribution, we aim at assessing the overall quality of the graduates’ university experience in terms of internal and external efficacy by applying the ECSI (European Customer Satisfaction Index) methodology, based on structural equation models and primarily developed in the context of customer satisfaction. For this aim, we propose a modified ECSI model tailored for the higher educational setting, explicitly taking into account the differences among groups of degree program. The study is carried out on data collected by the AlmaLaurea surveys at the University of Florence (Italy) in the period 2014–2017 and concerns a sample of more than 2,000 graduates. We find out eight latent variables that contribute to define the overall quality of university experience. These variables are differently affected by the type of degree program, with the highest levels of external efficacy observed for degree programs belonging to the educational, health, and engineering groups. It also turns out that interventions on the internal efficacy (i.e., quality of hardware and quality of humanware) have a direct positive effect on the university (i.e., loyalty) and an indirect positive effect on the society (i.e., external efficacy). 相似文献

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception
that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock
of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit
of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More
light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for
biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published
literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits
from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum
and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests
to future generations.

我国财产税制度存在的缺陷及其改革构想 总被引:8,自引:1,他引:8
财产税不仅是一种历史悠久的税收形态,而且是当今各国税制体系的重要组成部分,具有其他税种难以替代的作用。我国现行财产税制度在改革开放后虽然有所发展,但仍存在着税种缺失、税制老化等诸多问题,亟待改革。 相似文献

We study contracts designed to remunerate a farmer for the production of an ecosystem service with the payment dependent on the results of the farmer’s actions and on weather conditions. Two contracts are proposed: the first takes into account both the results of the farmer’s actions and a weather variable that reflects the actual atmospheric conditions during the life of the contract; the second bases the payment on the results alone incorporating only the average effect of weather. Social welfare is optimal when both the results and the specific atmospheric conditions are taken into account; however, this type of contract may be less acceptable to the farmer due to his perception of the level of risk involved.We thank two referees for valuable comments. 相似文献

中英电信"双寡头垄断"模式比较研究 总被引:9,自引:0,他引:9
中国电信南北分拆以后,将在固定电话和移动电话两个业务领域形成新一轮"双寡头垄断"竞争格局.英国是率先实行"双寡头垄断"作为过度,最终走向电信全面开放竞争的典范.中国电信业在1994~1999年第一阶段改革中,曾试图仿效"英国模式",构建中国电信和中国联通的"双寡头垄断",最终以失败告终.在中国即将形成新一轮"双寡头垄断"竞争格局之时,我们有必要通过对英国电信改革的理论背景、具体实施过程、取得的成就的回顾,探求英国"双寡头垄断"成功的奥秘,并为中国新一轮电信重组所借鉴,提升中国的电信业国际竞争力,更好地应对WTO的挑战. 相似文献

生态空间承载着人类、动植物和自然生态多种过程,是生态系统服务功能的策源地和枢纽区。以实施生态空间管控为导引,借助多源数据和ArcGIS、C-Plan系统工具,核心应用系统保护规划(SCP)技术,建立生态服务测度下市域生态空间管控体系的构建方法。基于此,以哈尔滨为例,以不可替代性为表征实现生态空间测度指标综合与功效评价,构建生态空间关键区识别、功能区优划以及网络格局优化模型,提出“重点保护-分区指引-格局优化”的市域生态空间管控体系,为新型城镇化及绿色发展战略的实施奠定科学基础和提供技术支撑。 相似文献

遗传算法是一种宏观意义下的仿生优化算法,它模拟生物在自然环境中的遗传和进化过程而形成的一种自适应全局优化概率搜索算法。这种算法可以用于对海量的客户信息进行搜索,提取对决策有用的信息,让企业在激烈的市场竞争中处于有利地位,最终达到最高利润。本文还通过一个简单的实例研究将该算法应用在客户关系管理中。 相似文献

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and
policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological
economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy
and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist
ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition
to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning,
development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship,
equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.
