Roles and Responsibilities of Stakeholders towards Ensuring Health and Safety at Construction Site

Health and Safety issues in the construction industry are of much concern to stakeholders, particularly because of their impact on the industry. This paper explored the roles and responsibilities of stakeholders in ensuring health and safety at the construction site. A well-structured interview guide was adopted for the qualitative study. Content analysis was adopted for the analysis of the results. The study revealed that the twelve roles identified by the stakeholders are only limited to the few laws and regulations they are aware of. Whereas the Contractors identified provision of welfare facilities, provision of health and safety policy, and health and safety plan as their key roles, the Consultants’ role was mainly limited to provision of competent site agent and provision of site layout. Abiding by the contractors’ instruction was identified by the Construction Workers as their key responsibilities. The local government officials also identified enforcement of CHS laws and regulations and reporting of incidents to the appropriate authorities, whereas the traditional authorities identified the enforcement of CHS laws and regulations including bye laws and enforcement of customs as their key roles. The findings further show that the stakeholders failed to appreciate some key roles and responsibilities enshrined in CHS laws and regulations in Ghana. The findings contribute to knowledge on stakeholders’ responsibilities in ensuring CHS, and provide valuable reference and insight to practitioners on the roles and responsibilities of the various stakeholders. It is recommended to train and educate stakeholders on all the relevant laws and regulations on CHS in order to improve health and safety at the construction site. The government should also set up a body such as Construction Authority to educate, coordinate, monitor and audit the activities of stakeholders to improve CHS at construction sites.

Evaluating Board Roles Performance in Adopting Corporate Social Responsibility （CSR） Practices

The purpose of this paper is to evaluate the board roles that make a board effective in the performance of adopting corporate social responsibility （CSR） practices. This paper examines directors＇ perceptions of the three main roles： monitoring, service, and strategic, which provide tools for critically understanding how the board adds the value in moving the organization towards more CSR practices. The stakeholder theory is used to distinguish the influence of the three main roles on the adoption of CSR practices. Primary data were collected for this research by conducting structured questionnaires with a sample of 461 directors from Saudi listed companies for study purpose. The results show that an appropriate mix of directors＇ roles and the development of sound board monitoring and service roles are the most crucial determinants of CSR adoption in Saudi listed companies. As the extant corporate governance and CSR literatures do not provide a clear perspective with contradictory outcomes about board roles in influencing CSR practices, the originality of this research is its contribution by evaluating the directors＇ perceptions of developing a direct relationship between the board roles and the adoption of CSR practices. Furthermore, the use of the stakeholder theory provides additional insights into identifying the most influential board role factors enhancing stakeholders＇ expectations of CSR practices.

Corporate Social Responsibility in the Thinking of Paolo Emilio Cassandro

This paper, which is to be collocated with international research studies of the historical origins of corporate social responsibility （CSR）, deals with both the theme of CSR itself and the topics related to it through an examination of the key characteristics of the theories of the master in the field of Italian Economia Aziendale, Paolo Emilio Cassandro （1910-2004）, who wrote an impressive number of works on numerous subjects that are of notable current relevance, including the social role of business, the concept of added value, and the role of the social report in the process of providing information for external purposes. Through an analytical-descriptive approach, our work will focus in particular on certain aspects of his life and works, which show beyond doubt the great value of his contribution to the advancement, at both national and international levels, of research into CSR. The main aim of what follows is to highlight not only the innovative nature of Cassandro＇s studies of the subject when compared with other research carried out in Italy in the second half of the 20th century but also how strikingly relevant they are to CSR as a topic for international scholars today.

锁相并网设备的独立激励-响应机制及基于幅频运动方程的设备特性表征方法

针对风电、光伏等电力电子并网设备对系统支撑能力评估问题,核心基础是正确认识设备根据有功/无功功率不平衡调节内电势幅值/频率的功能性角色(设备特性)。然而电力电子设备主流的锁相并网结构严重阻碍了对设备功能性角色的认知,特别是目前业界普遍基于锁相并网的具体连接结构,形成了设备内电势跟随电网电压或端电压变化的“跟网”角色认知,尚未认识到系统运行中设备所应具备的功能性角色。为此,首先通过深入认识隐藏在锁相并网结构下内电势响应取决于电流单独激励的电流控制独立激励-响应机制,澄清了锁相并网设备通过有功/无功功率不平衡独立调节内电势幅值/频率的功能性角色,进而提出基于有功/无功功率不平衡激励-内电势幅值/频率响应关系即幅频运动方程的设备特性表征方法,最后通过阐述锁相并网设备特性由功率激励-内电势响应关系表征的必然性,指出当前业界对锁相并网设备特性认知的局限。

Regulatory role of microRNA on inflammatory responses of diabetic retinopathy

The prevalence of diabetes has been increasing in the U.S., with diabetes as a significant concern for patients＇ physical and financial health. Diabetic retinopathy is the leading cause of vi- sual loss in working-age of adults and is characterized by retinal neurodegeneration and microvascular abnormalities in the eye. Hyperglycemia is one significant risk factor for diabetic retinop- athy and can result in increased inflammatory responses and vascular dysfunction. However, the molecular mechanisms un-derlying these pathologies are not fully understood. Although treatments are currently available for the patients with prolif-erative diabetic retinopathy or macular edema, including laser photocoagulation, steroids, or anti-vascular endothelial growth factor （VEGF） injections, many patients fail to respond to these therapies. Therefore, it is imperative to develop additional novel therapeutics for diabetic retinopathy.

Response to Comment on "The role of wildlife (wild birds) in the global transmission of antimicrobial resistance genes"

DEAR EDITOR,Since our first identification of plasmid-mediated colistin resistance gene mcr-1 in 2015 （Liu et al., 2016）, it has been described in human clinics, domestic animals, foods, and the environment worldwide （Schwarz ＆ Johnson, 2016）. Although it is still rare, the emergence of mcr-I in wild animals is of great concern. We summarized two previous reports on mcr-1 in wild birds from Lithuania and Argentina to describe its emergence and characteristics in wildlife and highlight the potentially important role of wild animals, particularly birds, in its global transmission （Wang et al., 2017）. The first detection of mcr-1 in wildlife in Asia was identified in an extended-spectrum β- lactamase-producing Escherichia coil strain isolated from Eurasian coot （Fulica atra）,
