基于LMDI的南京市工业经济能源消费碳排放实证分析   总被引：5，自引：2，他引：3  

史安娜  李淼 《资源科学》2011,33(10):1890-1896

工业经济的能源消费是碳排放的主要来源,研究城市工业经济能耗碳排放的特征和影响城市工业经济能耗碳排放的因素具有很强的代表性。本文以南京市为例,首先从碳排放总量和碳排放强度等指标分析了2000年-2009年南京市工业经济碳排放现状和特征,然后运用LMDI方法构建了南京市工业经济能耗碳排放因素分解模型,定量分析了2000年-2009年间产业规模、能源强度、能源结构和能源排放强度四个影响因素对南京市工业经济碳排放的影响。研究结果表明,产业规模效益是南京市工业经济碳排放增长的主要促进因素,能源强度效应是南京市工业经济碳排放增长的主要抑制因素,能源结构效应和能源排放强度效应对南京市工业能源结构效应没有明显变化。在此基础上,提出了减排的相关政策建议。  相似文献   

Positive functions of emotions in achievement sports     

Puig N  Vilanova A 《Research quarterly for exercise and sport》2011,82(2):334-344

This article presents the results of two research projects on the emotions of men engaged in achievement outdoor sports. The conditions were analyzed under which emotions carry out positive functions. The question strikes us as a fundamental one, because it is of crucial importance when it comes to increasing sportspeople's success. The theoretical framework applied was that of microfunctionalism. The method, of a qualitative nature, was based on in-depth interviews, each lasting between 1.5 and 2 hr with a total of 14 sportspersons. The results show that in order for emotions to fulfill positive functions, three conditions must be met: (a) existence of passion, which, with its dialectical character of pleasure and suffering underlies all the other emotions and acts as a motor that pushes the sportsperson forward, despite all the contretemps he might meet on the way; (b) intense emotion work, which may be conducted only if accompanied by knowledge and experience of the natural environment acquired over the years; and (c) conciliation between emotion work and the feeling rules characteristic of each sport subculture. For those individuals who pursue achievement in outdoor sports, these results will provide more concrete indications regarding how to carry out the emotional preparation required for these sports.  相似文献   

Evaluating Chinese government WeChat official accounts in public service delivery: A user-centered approach     

Tingting Jiang  Ying Wang  Tianqianjin Lin  Lina Shangguan 《Government Information Quarterly》2021,38(1):101548

WeChat official accounts have been increasingly adopted by Chinese government agencies to deliver public services, in response to the “Internet + Public Service” reformation. While previous studies depended heavily on the expert-oriented approach to evaluate the accounts, this paper presents a user-centered study based on a mixed methods research design in which an unobtrusive clickstream data analysis was complemented by a card sorting study, stakeholder interviews, and a focus group. A 2-month server log file containing 42,188,760 clickstream records was obtained from an active government WeChat official account and analyzed at the movement level, which found that the account was mainly used as a lookup tool with most services underutilized and its home portals failed to support effective wayfinding to needed services. Deficiencies in information architecture, operation strategy, and interaction design of the account were identified in the complementary studies. This study not only enriches the knowledge about social media use in the Chinese government for public service delivery, but also introduces innovative methods to generate new research insights. The findings can inform government WeChat official accounts of how to improve service quality and user experience.  相似文献   

Public libraries embrace citizen science: Strengths and challenges     

Anna Cigarini  Isabelle Bonhoure  Julián Vicens  Josep Perelló 《Library & information science research》2021,43(2):101090

Can public libraries become hubs for citizen science? In line with the principles of citizen science, this question was answered collaboratively with librarians from the Barcelona Network of Public Libraries who performed two hands-on activities. One activity was a training course taken by 30 librarians from 24 different libraries which enabled them to envisage citizen science implementation at each library. The other activity consisted of co-creating a citizen social science project and involved 40 library users, seven librarians from three different cities, and professional scientists. The analysis considers the perspectives of both librarians and users, through participant observation, surveys, and a focus group to identify strengths and challenges. The overall results suggest that public libraries can offer leadership in the promotion of citizen science and contribute to the mission of public libraries to act as local community hubs. The main challenges identified were related to the complexity of collaboration, uncertainty regarding research co-creation, and participant retention strategies.  相似文献
