Changes in public trust in physicians: empirical evidence from China

Dahai Zhao, Zhiruo Zhang

《医学前沿（英文）》 2019年第13卷第4期页码 504-510 doi: 10.1007/s11684-018-0666-4

摘要： Studies examining the trends in public trust in physicians have provided a considerable amount of valuable policy implications for policymakers compared with cross-sectional studies on this topic in many countries. This study investigated changes in public trust in physicians in China based on two cross-sectional national surveys conducted in 2011 and 2016 and identified the determinants of these changes. The results indicated 83.4% of respondents in 2011 reported trust or strong trust in physicians in China, which decreased to 64.2% by 2016. The results of ordinal logistic regression demonstrated that public trust in physicians in China had decreased significantly from 2011 to 2016 ( <0.001) after adjusting for other independent variables. Self-reported health status, self-rated happiness, and self-identified social class were all associated positively with public trust in physicians in China. The results also confirmed that decreasing public satisfaction with the most recent treatment experience was the major determinant of decreasing public trust in physicians in China. The findings of this study suggest that decreasing public trust in physicians deserves considerable attention from national policymakers and that improving satisfaction with treatment experiences would be the most effective strategy for enhancing public trust in physicians in China.

Xin WANG, Ying WANG, Jian-hua GUO

《信息与电子工程前沿（英文）》 2017年第18卷第10期页码 1591-1600 doi: 10.1631/FITEE.1601341

摘要：由于用户信任关系具有一定稀疏性和动态性，准确预测在线社交媒体中的信任关系变得较为困难；此外，大多数社交媒体平台都没有提供明确的信任关系。这些因素使得预测信任关系并构建信任网络具有一定挑战性。首先，验证了利用稀疏学习模型能够较好实现信任关系预测；然后，提出一个新颖框架bTrust，不使用任何信任关系，仅仅利用交互数据和同质性效应构建信任网络；最后，在Epinions和Ciao两个真实数据集上验证了bTrust框架的有效性，表明交互行为和同质性效应在构建信任网络中的重要性。

《医学前沿（英文）》 2018年第12卷第2期页码 218-223 doi: 10.1007/s11684-017-0534-7

摘要：

Reforms in public hospitals are among the most important improvements in China’s health care system over the last two decades. However, the reforms that should be implemented in public hospitals are unclear. Thus, a feasible direction of reforms in Chinese public hospitals is suggested and reliable policy suggestions are provided for the government to reform public hospitals. The data used in this study were mainly derived from a qualitative study. Focus group discussions and in-depth interviews were conducted in Shanghai, Guangdong, and Gansu between May and December 2014. Government funding accounted for approximately eight percent of the total annual revenue of public hospitals in China, and the insufficient government subsidy considerably affects the operation mechanism of public hospitals. However, solely increasing this subsidy cannot address the inappropriate incentives of public hospitals in China. The most crucial step in setting the direction of reforms in public hospitals in China is transforming inappropriate incentives by implementing a new evaluation index system for directors and physicians in public hospitals.

The Routine and Emergency Coordinated Management of Public Security

Ning Liu

《工程管理前沿（英文）》 2015年第2卷第4期页码 331-338 doi: 10.15302/J-FEM-2015063

摘要： The paper presents a study based on the observation of public security programme situations. Nowadays, public security management is faced with challenges such as the increase in non-traditional safety threats, high occurrence probability, obvious complex chain reactions, high security demand, vulnerable bearing systems and world-wide influences. For the new adapted requirements of public security management, this paper puts forward the concept of the coordinated routine and emergency management, which combines the routine management at normal status and the emergency management at the abnormal status based on the whole process of public security management. This paper analyzes the coordinated management system and establishes the decision-making objectives, decision-making model and constraints. In addition, this paper proposes the basic strategy of achieving the coordinated management of public security.

Connecting Information to Promote Public Health

Xue-mei Su,Jia Zhao

《工程管理前沿（英文）》 2016年第3卷第4期页码 384-389 doi: 10.15302/J-FEM-2016054

摘要： With the development of information technology in the past 12 years, China has established the specialized or vertical web-based information systems for data collection of disease and related risk factor. These information systems are described as public health information systems (PHIS) in China. When PHIS has thus evolved in a haphazard and fragmented way under the pressure administrative, economic and legal, local health workers who are overburdened with multiple and time-consuming reporting requirements cannot deliver timely, accurate and complete data. Seeing that the information of disease surveillance is provided by hospitals and health service centers in China and that the development of electronic medical record (EMR) and electronic health record (EHR) occurs under the policy and investment of health since 2009 in China, there should be a connection and data sharing mechanism between EMR (EHR) and PHIS to support public health surveillance and public health decision-making. The paper aims at discussing current status and problems of PHIS in China, making a brief introduction on the blueprint of health information technology in China, exploring solution for interoperability between PHIS and EHR (EMR), and sharing some experiences and lessons from pilot project on automatic notifiable infectious disease reporting.

Tender evaluation through efficiency analysis for public construction contracts

Stefan NIEWERTH, Peter VOGT, Markus THEWES

《工程管理前沿（英文）》 2022年第9卷第1期页码 148-158 doi: 10.1007/s42524-020-0119-z

摘要： Given the European Public Procurement Directive 2014/24/EU, policymakers have ordered the inclusion of various criteria, such as the price, life-cycle costs, environmental, and social aspects, in the evaluation of tenders for public construction projects. Consequently, the relevance of non-monetary award criteria has gained significant value. However, the established evaluation formulas, which are used to obtain the best value for money procurement, have resulted in legal disputes. The existing evaluation formulas exhibit mathematical weaknesses, wherein scoring indices do not express economic efficiency adequately. Thus, a conflict is observed between the political requirement of non-monetary award criteria and their evaluation by contracting authorities. To overcome such dilemma, an extensive literature review is conducted. Specifically, this study explores the essential problems of existing evaluation formulas and develops a more reliable method. The technique from the field of efficiency analysis, i.e., Data Envelopment Analysis (DEA), is adopted in this study. For contract awarding, the DEA is extended by introducing a decision theoretical framework. For public procurement, the proposed method combines two advantages. First, the proposed method ensures the derivation of a robust tender ranking given that with respect to clients’ preferences, irrelevant and insufficiently tailored tenders do not influence the scoring. Second, the proposed method supports the intention of policy makers to promote public goals, such as sustainable aspects. By disclosing the strengths and weaknesses of bidders with respect to their competitors, all bidders can obtain a precise overview of their performance regarding the award criteria. In sum, the proposed method allows a targeted improvement of certain criteria values in future tenders and consequently leads to an enhancement of public goals.

Robust public-private partnerships for joint railway and property development

Ka Fai NG, Hong K. LO, Yue HUAI

《工程管理前沿（英文）》 2017年第4卷第4期页码 437-450 doi: 10.15302/J-FEM-2017068

摘要： The involvement of the private sector in the construction or operation of an infrastructure project may enhance the financial viability of projects, which facilitates the formation of public-private partnership (PPP) for project delivery. PPP exploits the strength of the private sector by shifting certain project risks from the public party to the private sector who can efficiently manage certain risks. In joint railway and housing development, the approach of bundling railway and housing development (R&HD) allows cross-subsidization between immense railway construction cost and profitable housing rental revenue. This approach also provides flexibility in incorporating PPP models by distributing railway and housing revenues and costs and their inherent risks properly to the public and private sectors. Ng and Lo (2015a) developed an evaluation framework for joint railway and property development, which evaluates PPPs based on financial and construction criteria for selecting the best suitable PPP for a particular project. This study, which is based on the framework in Ng and Lo (2015a), aims to examine the robustness of various PPP configurations. This study analyzes the effects of PPP configurations on stakeholders’ risks and returns under population or demand growth and railway construction cost uncertainties. The eventual outcome of particular PPP configurations is also examined. This study also seeks to answer the following questions: How would optimal configuration change under highly volatile population and railway construction cost? Are there PPP configurations that are robust to these uncertainties and those that are sensitive to a particular uncertainty? This understanding is critical for managing risks and facilitating the formation of appropriate PPP for R&HD.

Heat prices for public buildings in Tianjin

Boyuan HAO,Zhe TIAN,Yan DING,Peng PENG

《能源前沿（英文）》 2016年第10卷第3期页码 249-259 doi: 10.1007/s11708-016-0412-z

摘要： Energy-saving awareness of heat users and heating enterprises can be stimulated by implementing heat metering for public buildings and by establishing scientific and reasonable policies for heat prices in China. In this paper, a two-part heat price for public buildings in Tianjin is introduced, which divides the heat price into a basic part and a metering part. According to the statistical analysis of information collected from two pilot heating enterprises, the specific heat load for public buildings in Tianjin is calculated, and three candidate schemes of heat price are proposed. A simulation of heat cost is also conducted, and the benefits for both heat users and heating enterprises are balanced. Finally, the two-part heat price for public buildings in Tianjin is determined: the basic heat price is recommended to be 20 CNY/m , and the metering heat price is recommended to be 76.10 CNY/GJ. Such a price could be implemented in the initial stage of heat metering for public buildings in Tianjin.

Theoretical Analysis of Public Rental House Supply

Yue Teng,Bo Xu,Xiao Li,Ling Li,Xia-zhi Fang

《工程管理前沿（英文）》 2014年第1卷第4期页码 372-377 doi: 10.15302/J-FEM-2014056

摘要： The public rental house (PRH) plays a significant role in our housing security system. Using the theory of public goods, both government and private enterprises have advantages and disadvantages in supplying the PRH. In order to optimize the present supply system of the PRH, this article introduces the delivery pattern of public and private partnerships (PPP) into the government allocation system, and improves it into public-intermediary-private-partnerships (PIPP), a new supply system through government, private enterprises and intermediary organization cooperation. It helps to better achieve the security role of the PRH in our society.

Sustainable public-private partnerships: Balancing the multi-actor ecosystem and societal requirements

Pekka Leviäkangas, Yanbing YE, Oluwole Alfred OLATUNJI

《工程管理前沿（英文）》 2018年第5卷第3期页码 347-356 doi: 10.15302/J-FEM-2018020

摘要：

The funding gap of public infrastructure networks (roads, railways, ports, electricity, and energy lines) can be solved partly by introducing private capital for investments, i.e., public-private partnerships (PPP). This paper introduces an integrated model of a PPP project and investigates its implications on PPP policies and strategies regarding appropriate project appraisal and selection. The model has different resolution levels, namely, project level, business ecosystem level, and market and societal levels. The integrated model suggests that investing in merely financially viable projects is insufficient to realize economically and socially sustainable and acceptable projects.

摘要：

This study aims to explore the prevalence and determinations of physical inactivity among hospital employees in Shanghai, China. A cross-sectional study of 4612 employees aged 19 to 68 years was conducted through stratified cluster sampling from different classes of Shanghai hospitals in 2011. The total physical activity was evaluated using the metabolic equivalent according to the Global Physical Activity Questionnaire. Among the participants, 38.5%, 32.3%, and 64.6% of the employees are inactive at work, commuting, and taking leisure time, respectively. Up to 41.8% of the men and 37.8% of the women (P = 0.012) are physically inactive. When the age and educational level are adjusted, male doctors and medical technicians show a higher percentage of physical inactivity than male workers in logistics (P = 0.001). Among females, employees who are working in second- and third-class hospitals show a higher proportion of physical inactivity than those who are working in community health care centers. Logistic regression analyses show that the odds ratios (ORs) of leisure-time physical inactivity associated with the intensity of physical activity at work are 2.259, 2.897, and 4.266 for men (P<0.001) and 2.456, 3.259, and 3.587 for women (P<0.001), respectively. The time during commuting activities is significantly associated with leisure-time physical inactivity in either sex (OR= 2.116 for men and 2.173 for women, P<0.001). Hospital employees, particularly doctors and medical technicians, show a higher proportion of physical inactivity than other inhabitants in Shanghai. The time and intensity of activity at work and commuting are associated with leisure-time activities.
