面向对象和设计模式在ISS管理系统中的应用

提出了利用面向对象和设计模式方法作为ISMS的设计新方法,并使用UML语言描述了面向对象和设计模式在综合传感器管理系统(ISMS)中的具体应用,在系统的设计和开发中取得了较好的效果。最后进一步指出了面向体系结构(SOA)模式为以后ISMS的设计新方向。     

The foreign expansion of a service company: The case of ISS A/S

The internationalization of business increasingly is led by service sectors, particularly services based on highly skilled labour industries. This article explores a quite different range of services – those that employ low-skilled workers in labour-intensive services. The article is based on the case of ISS – International Service Systems – which over the past four decades has pursued an aggressive internationalization strategy. The article describes the foreign expansion history in the period from 1960 to the year 2000 that reflected the vision of top management in combination with the development of a unique business model. In order to explain its development, three theoretical frameworks are highlighted, and it is shown that the resource-based view offers a convincing frame of interpretation.     

腹部外伤合并颅脑创伤男性患者早期血清孕酮的临床意义

目的对比腹部外伤合并颅脑创伤男性患者与单纯腹部外伤男性患者的血清孕酮值,探讨其临床变化意义。方法收入我院2013年1月至11月急诊外科收治的急性腹部创伤男性患者116例,分成腹部外伤合并颅脑损伤组及单纯性腹部外伤组,并以ISS(创伤严重度评分)分值评价创伤患者机体损伤的严重程度。另选40例健康成年男性为对照组。于伤后后12、24、36、48h行放射免疫双抗体沉淀法测定血清孕酮水平,并进行数据比较。结果两组患者均随腹部外伤的ISS评分增高,早期血清孕酮值相比对照组越高(P<0.05)。但合并颅脑损伤组在相同ISS评分、相同时间点下早期血清孕酮值相比非颅脑损伤患者有明显升高,具有统计学意义(P<0.05)。结论血清孕酮在急性颅脑损伤中可作为一种特异性临床指标,指示患者的脑功能损伤严重程度,提供一定的基础临床资料。     

Firm performance and mutual fund voting

We employ a new comprehensive proxy voting records database to investigate whether mutual funds consider prior firm performance when they vote on a diverse range of management- and shareholder-sponsored proposals relating to governance, compensation, and director election. We argue that prior firm performance plays a role in the monitoring effort of mutual funds as they fulfill their fiduciary duties. Results show that voting is related to prior firm performance for selected management and shareholder proposals and that it is consistent with Institutional Shareholder Services’ recommendations. Mutual funds support management (shareholder) proposals less (more) when prior firm performance has been weak. Furthermore, even when mutual funds deviate from their fund family’s voting policies, they attach importance to prior firm performance, and their voting is, to a certain degree, affected by business ties.     

Point of adoption and beyond. Initial trust and mobile-payment continuation intention

Initial trust represents the trust that develops upon first use of a product. It is built on the basis of the net effect of factors that stimulate as well as inhibit it. Future transactions require less consumer effort after initial-trust formation. Despite being recognized as an important factor affecting the adoption of innovations, initial trust has been not been greatly explored by prior scholars. The present study remedies this gap by invoking the information systems success (ISS) model, transaction cost economics (TCE) theory, and the IT continuance model to propose a two-step framework that includes the antecedents of a pre-adoption factor, such as initial trust, and post-adoption factors, such as confirmation, perceived usefulness, satisfaction, and continuation intention toward mobile-based payments. Cross-sectional data of 954 first-time mobile-wallet users are analyzed to test the framework. The study findings suggest that information and service quality positively influence initial trust, which, in turn, has a positive association with confirmation and perceived usefulness. Results also reveal a positive relationship between perceived usefulness and continuation intention. These results pave the way for making useful recommendations for future researchers. The study also discusses various inferences that can improve managerial efficacy in promoting the use of mobile-based payment methods.     

Do Corporate Governance Analysts Matter? Evidence from the Expansion of Governance Analyst Coverage

T his paper examines the economic consequences of the initiation of governance analyst coverage. Governance analysts process, enhance, and disseminate governance‐related information to capital market participants via, for example, governance reports and ratings. Using an exogenous shock in the United Kingdom, I find that an increase in governance analyst coverage results in increased governance quality, improved liquidity, increased financial analyst following, and improved investor breadth. These findings are consistent with governance analysts creating value for firms via monitoring, information dissemination/production, and investor recognition.     

Measuring Knowledge Development and Developing Official Statistics for the Information Age

Measuring knowledge development is a new statistical activity that warrants urgent attention in the light of the current Internet explosion. The Internet creates virtual networks by connecting information nodes, knowledge nexus, people and institutions. The Internet has resulted in an unprecedented proliferation of Information, Communication, Knowledge and Entertainment (ICKE), which has in turn brought about structural changes in all aspects of social, economic and political governance. For public policy formulators, including the statistical community, it is imperative that the knowledge development aspect of ICKE be measured. Being abstract, knowledge is difficult to quantify. However, the manifestations of attributes and variables of any knowledge development activity are measurable. The paper outlines a conceptual framework for achieving this. This proposed framework adopts a socio-technological approach, premised on contemporary information and knowledge development as an integral of the people and technology dimensions. To illustrate the workability of the proposed model, the paper identifies some parameters and variables in the current statistical system, and highlights some new data generated via the Internet Subscriber Study and ICT Exposition Visitor Study. All illustrations refer to Malaysian data. Finally, the paper outlines 'way forward' initiatives for establishing a full-fledged set of information and knowledge development indicators.
