Purpose - The proliferation and advance of web-based technologies create expanded opportunities for retailers to gain a better understanding of their customers. However, the success of these ...web-based discussion boards depends solely on whether customers are willing to share their knowledge and experience with other customers in these discussion boards. Thus, this study aims at identifying the factors that drive knowledge sharing among customers in web-based discussion boards.Design methodology approach - An exploratory study with 104 respondents was conducted to identify and categorize the key factors of customer knowledge sharing in web-based discussion boards.Findings - The results indicate that the enjoyment of helping others is the most frequently cited reason for customer knowledge sharing in web-based discussion boards. On the other hand, the lack of knowledge self-efficacy is the mostly cited reason explaining why customers do not want to share knowledge with others.Research limitations implications - The exploratory analysis suggests that the underlying reasons that motivate and inhibit customers to share are very different. There is a need to integrate multiple theoretical perspectives from across the social and technical domains if this phenomenon is to be better understood.Practical implications - Building upon the findings of this study, some generic guidelines for retailers and web designers for promoting customer sharing in web-based discussion boards are outlined.Originality value - This research is one of the first studies to use the socio-technical perspective to investigate customer knowledge sharing phenomena in web-based discussion boards.
From publicly available data, we identified two national culture dimensions, individualism-collectivism and uncertainty avoidance, and their interaction that influences Internet shopping rates across ...a wide spectrum of countries. Together, these factors accounted for 14% of the explained variance (on top of the combined variance of 63% explained by national income level, educational level, economic growth rate, unemployment rate, and crime rate) in predicting Internet shopping rates. For countries lower in uncertainty avoidance, individualist cultures show higher Internet shopping rates than do collectivist cultures. Implications for national- and Internet firm-level web design strategies are discussed.
The prevalent multichannel shopping environment is driving many consumers to choose between online and offline channel at the information search and product purchase stages of a shopping experience. ...Consequently, multichannel retailers face the challenges of identifying different target consumer groups and maximizing the value of each channel by understanding and serving each group more effectively. Hence, this study attempts to identify consumer segments by examining consumers' perceived channel values at different shopping stages. The latent class MNL (LC-MNL) method, as a powerful tool that is able to detect consumer heterogeneity in the same consumption scenarios, is applied to conduct consumer segmentation analysis based on the consumer's perceived values, including channel benefits and costs, as well as different channels' characteristics. By using the survey data of 1325 consumers, results indicate two segments comprising innovative consumers and conventional consumers in terms of online vs. offline channel usage. Furthermore, the logit regressions for segments estimation illustrate that the two segments are significantly different in terms of channel attributes and consumers' intrinsic channel preferences. This study contributes to the extant electronic commerce and multichannel marketing literature by designing a rigorous consumer segmentation method which incorporates both interpretation and prediction capabilities and analyzing the underlying influential factors for different segments. The results can further provide useful guidance to marketing and sales practitioners in designing effective channel attributes to meet the needs of consumers belonging to different segments.
Gate length down-scaling of silicon-based transistor results in very small on-state drain-source resistance, making it challenging for test engineers to perform precise and repeatable wafer ...measurements. Size reduction of aluminum-capped copper test pads to save on lithography, prototyping and production costs implies that it is very difficult to re-probe the same device with low contact resistance. Novel true-Kelvin MEMS analytical DC probes, new test and modelling strategies are proposed in this paper to address these emerging test challenges.
This paper demonstrates a novel RFCMOS process monitoring test structure. Outstanding agreement in dc and radio frequency (RF) characteristics has been observed between conventional test structure ...and the new process monitoring test structure for MOSFET with good correlations in measured capacitances also noted for metal-insulator-metal capacitor and MOS varactor. Possible process monitoring test structure is also suggested as a reference benchmarking indicator for interconnects.

This paper presents the formation of the parasitic components that exist in the RF MOSFET structure during its high-frequency operation. The parasitic components are extracted from the transistor's ...S-parameter measurement, and its geometry dependence is studied with respect to its layout structure. Physical geometry equations are proposed to represent these parasitic components, and by implementing them into the RF model, a scalable RFCMOS model, that is, valid up to 49.85 GHz is demonstrated. A new verification technique is proposed to verify the quality of the developed scalable RFCMOS model. The proposed technique can shorten the verification time of the scalable RFCMOS model and ensure that the coded scalable model file is error-free and thus more reliable to use.
Implementing energy-efficient optical transceiver modules with silicon photonics (SiPh) and 3DIC technologies will help alleviate the increasing energy consumption for hyperscale data centers. To ...facilitate effective 3DIC heterogenous integration of these photonics integrated circuits for optical transceivers, high precision, repeatable and reliable SiPh wafer acceptance tests are essential and vital. This paper successfully demonstrated incident angle optimization for optical wafer tests as well as evaluation of a fully automatic SiPh wafer test architecture that is accurate and dependable, achieving excellent test correlations between passive and active devices designed with grating-couplers and edge couplers.
Developing common standards, such as eXtensible Business Reporting Language (XBRL), to smoothen information sharing in the value chain is considered the leading issue for releasing the potential of ...e-business. Data standards such as XBRL play a critical role in an increasingly networked environment. Despite promises of XBRL to improve data accuracy, few empirical studies have tested the impact of early XBRL adoption on the quality of information. Theories explaining information technology (IT) productivity paradox indicate that value realization from IT innovations may experience time lag due to the need for technology refinement and diffusion. This study examines the impact of early adoption of XBRL on analysts’ forecast accuracy with empirical data of Chinese firms. The uncertainty related to the unproven technology, such as information errors, has decreased analysts’ forecast accuracy during the early adoption period among firms in an economy with little public information on listed firms. Our findings have practical implications that will facilitate the quality improvement of financial information in a networked business environment. Our findings highlight the importance of quality assurance and policy enforcement for value realization from XBRL adoption to regulators, filers, information consumers, the accounting profession and other stakeholders.
The adoption of an organization-wide system, such as an enterprise system (ES), has often been mandated by organizational management, which may not necessarily motivate users to proactively explore ...the system's features and subsequently apply pertinent features that best support their job tasks. Anchoring on self-determination theory, this research investigates the antecedents and consequences of users' intrinsic motivation to explore ES features. We propose two organizational levers (i.e., autonomous job design and socialization tactics) that the management could exercise to trigger intrinsic motivation, thereby leading to improved ES feature exploration. Intrinsic motivation is manifested by hedonic motivation and normative motivation, whereas ES feature exploration is conceptualized as a dual-dimensional outcome reflected by cognitive behavior (exploratory usage) and positive affect (exploration satisfaction). Through a two-stage survey of 127 organizational users in China, we find general support for our research model. We further observe significant moderating effects of prevention focus on the association between organizational levers and intrinsic motivations. Beyond demonstrating how organizational users respond to different organizational levers, this research examines a broader, enduring challenge, which is to determine how organizational users can be induced to be intrinsically inspired to innovatively harness implemented information systems.
