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.

抗泄露的CCA2安全的无证书公钥加密机制 None

Yan-wei ZHOU, Bo YANG, Hao CHENG, Qing-long WANG

《信息与电子工程前沿（英文）》 2018年第19卷第4期页码 481-493 doi: 10.1631/FITEE.1601849

摘要：近年来，存在密钥泄露环境下密码学机制的安全性成为该领域研究热点，一些能够抵抗泄露攻击的密码学原语相继被提出。由于现有相关构造中，抗泄露密码学原语无法保证其输出对于任意多项式时间敌手完全随机，因此敌手能够从相应抗泄露密码学原语的输出中获知密钥部分信息。为获得更佳性能，提出一个抗泄露的CCA2安全的无证书公钥加密机制，基于经典的判定性Diffie-Hellman假设证明了该方案的安全性。分析显示，对于任意敌手，该方案输出均完全随机，使得敌手无法从给出的密文中获知密钥相关信息；此外，该方案具有较高泄露率。由于这些良好特性，该方案在实际应用中具有广泛应用前景。

Qualitative analysis of direction of public hospital reforms in China

null

《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.

《工程管理前沿（英文）》 2020年第7卷第4期页码 485-499 doi: 10.1007/s42524-020-0140-2

摘要： The infrastructure finance gap has long-standing implications for economic and social development. Owing to low efficiency, high transaction costs, and long transaction time, conventional infrastructure financing instruments are considered to be major contributors to the increasing mismatch between the need for infrastructure development and available financing. Implemented through smart contracts, blockchain tokenization has shown characteristics that are poised to change the capital stack of infrastructure investment. This study analyzed the first SEC-compliant energy asset security token, ZiyenCoin, from the perspective of the key participants, relevant regulations, and token offering procedures. Results show that tokenization can improve infrastructure assets liquidity, transaction efficiency, and transparency across intermediaries. Conventional infrastructure financing instruments were compared with blockchain tokenization by reviewing the literature on infrastructure finance. The benefits and barriers of tokenizing infrastructure assets were thoroughly discussed to devise ways of improving infrastructure financing. The study also found that the potential of tokenization has not yet been fully realized because of the limited technical infrastructures, regulation uncertainties, volatilities in the token market, and absence of the public sector. This study contributes to the present understanding of how blockchain technology can be implemented in infrastructure finance and the role of tokenization in the structure of public–private partnership and project finance.

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.

《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.

《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.
