Data Warehousing Process Maturity: An Exploratory Study of Factors Influencing User Perceptions

This paper explores the factors influencing perceptions of data warehousing process maturity. Data warehousing, like software development, is a process, which can be expressed in terms of components such as artifacts and workflows. In software engineering, the Capability Maturity Model (CMM) was developed to define different levels of software process maturity. We draw upon the concepts underlying CMM to define different maturity levels for a data warehousing process (DWP). Based on the literature in software development and maturity, we identify a set of features for characterizing the levels of data warehousing process maturity and conduct an exploratory field study to empirically examine if those indeed are factors influencing perceptions of maturity. Our focus in this paper is on managerial perceptions of DWP. The results of this exploratory study indicate that several factors—data quality, alignment of architecture, change management, organizational readiness, and data warehouse size—have an impact on DWP maturity, as perceived by IT professionals. From a practical standpoint, the results provide useful pointers, both managerial and technological, to organizations aspiring to elevate their data warehousing processes to more mature levels. This paper also opens up several areas for future research, including instrument development for assessing DWP maturity.     

An Empirical Study of E-Business Implementation Process in China

E-business successes in traditional organizations have prompted much interest among researchers in many disciplines such as strategic management, information systems, and economics. However, the complexity of e-business implementation process has been overlooked, and it remains unclear. This paper investigates causal relationships among strategic initiative, information technology (IT)-related resources, and e-business capabilities; and their roles in the implementation process. From the resource-based view (RBV) of a firm and e-business strategic standpoint, we propose a model of e-business implementation process. We divide the process into four stages, and 11 hypotheses are developed in seeking relationships among six proposed constructs. Drawing from a sample of 56 enterprises within Hubei Province in China, we provide theoretical support for a critical causal link from e-business strategic initiatives to utilization of IT-related resources, and consequently, creating distinctive e-business capabilities. We find that information sharing capabilities are intermediate and transferable forces that help translating IT-related organizational resources into the collaborative process capabilities. The causal relationships expand our understanding of the dynamics of organizational transformation enabled by the Internet. The practical implications offer managers guidelines to the roles played by strategy, resource, and capabilities for e-business success. It helps in recognizing the value of their potential contributions to the organization as a whole.

Consumer Acceptance of RFID Technology: An Exploratory Study

Radio frequency identification (RFID) technology is used in numerous applications and offers a plethora of interesting potential new applications. However, this potential raises issues that require addressing to achieve its widespread acceptance by consumers. This paper investigates the factors that affect consumer acceptance of RFID technology. The purpose of this effort is to develop and test a theoretical model that contextualizes the technology acceptance model (TAM) within the context of RFID technology. The research model proposes that convenience, culture, privacy, regulation, and security are the principal factors influencing the consumerspsila acceptance of RFID. However, the results show that convenience, culture, and security are significant predictors. This study is the first in the RFID literature to use the TAM for explaining consumer acceptance of RFID technology. The findings suggest that: (1) higher perceived convenience of RFID technology leads to greater acceptance of this technology; (2) societal beliefs, value systems, norms, and/or behaviors influence the extent of consumer acceptance of RFID technology; and (3) higher perceived importance of and less willingness to sacrifice personal information security lead to lower intention to use RFID technology. Contextualization of TAM to RFID technology makes this study relevant to practitioners because the results can provide insight to organizations using or exploring the use of RFID technology.

对纳米硅薄膜高电导机制的探讨

使用超高真空PECVD薄膜沉积系统制备的纳米桂薄膜（nc－Si：H）具有高电导特性。为了探讨其导电机制，先使用K．Yoshida早期提出的两相无序结构有效电导模型分别对晶粒电导和界面电导进行了理论计算。指出，nc－Si：H股中高电导主要来自于细微晶粒的传导，界面可视之为非导体。另一方面，实验证实nc－Si：H股的电导率随平均品粒尺寸减少而增大，具有明显的小尺寸效应。文中首次提出，nc－Si：H膜的微晶粒具有异质结量子点（HQD）特性，并按此模型对nc－Si：H膜的电导率实验曲线进行了讨论。理论与实验结果符合得很好．又得出，硅薄膜结构在其晶态体积百分比Xc=0．30和0．70处呈现出两个明显的相变点。
