Smart card-based E-payment systems are receiving increasing attention as the number of implementations is witnessed on the rise globally. Understanding of user adoption behavior of E-payment systems that employ smart card technology becomes a research area that is of particular value and interest to both IS researchers and professionals. However, research interest focuses mostly on why a smart card-based E-payment system results in a failure or how the system could have grown into a success. This signals the fact that researchers have not had much opportunity to critically review a smart card-based E-payment system that has gained wide support and overcome the hurdle of critical mass adoption. The Octopus in Hong Kong has provided a rare opportunity for investigating smart card-based E-payment system because of its unprecedented success. This research seeks to thoroughly analyze the Octopus from technology adoption behavior perspectives.
Cultural impacts on adoption behavior are one of the key areas that this research posits to investigate. Since the present research is conducted in Hong Kong where a majority of population is Chinese ethnicity and yet is westernized in a number of aspects, assuming that users in Hong Kong are characterized by eastern or western culture is less useful. Explicit cultural characteristics at individual level are tapped into here instead of applying generalization of cultural beliefs to users to more accurately reflect cultural bias. In this vein, the technology acceptance model (TAM) is adapted, extended, and tested for its applicability cross-culturally in Hong Kong on the Octopus. Four cultural dimensions developed by Hofstede are included in this study, namely uncertainty avoidance, masculinity, individualism, and Confucian Dynamism (long-term orientation), to explore their influence on usage behavior through the mediation of perceived usefulness.
TAM is also integrated with the innovation diffusion theory (IDT) to borrow two constructs in relation to innovative characteristics, namely relative advantage and compatibility, in order to enhance the explanatory power of the proposed research model. Besides, the normative accountability of the research model is strengthened by embracing two social influences, namely subjective norm and image. As the last antecedent to perceived usefulness, prior experience serves to bring in the time variation factor to allow level of prior experience to exert both direct and moderating effects on perceived usefulness.
The resulting research model is analyzed by partial least squares (PLS)-based Structural Equation Modeling (SEM) approach. The research findings reveal that all cultural dimensions demonstrate direct effect on perceived usefulness though the influence of uncertainty avoidance is found marginally significant. Other constructs on innovative characteristics and social influences are validated to be significant as hypothesized. Prior experience does indeed significantly moderate the two influences that perceived usefulness receives from relative advantage and compatibility, respectively. The research model has demonstrated convincing explanatory power and so may be employed for further studies in other contexts. In particular, cultural effects play a key role in contributing to the uniqueness of the model, enabling it to be an effective tool to help critically understand increasingly internationalized IS system development and implementation efforts. This research also suggests several practical implications in view of the findings that could better inform managerial decisions for designing, implementing, or promoting smart card-based E-payment system.

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Government policy can alleviate inequities in living standards. Disabled people often qualify for government assistance which is one way that their living standard can improve, although arbitrary systems for distributing assistance are not likely to serve equity objectives. The purpose of this paper is to indicate the key variables to which government should direct attention, in order to alleviate both horizontal and vertical inequity in grants to disabled people.
There is no literature, either theoretical or empirical, that specifically addresses this problem. This paper invokes important economic concepts associated with the nineteenth century English philosopher/economist, John Stuart Mill, as well as the 1998 Nobel Laureate in Economics, Amartya Sen. Mill's general conception of how government should behave in treating citizens was elaborated subsequently in the public finance literature on principles of taxation. These notions are about “the equal treatment of equals” and “the unequal treatment of unequals”. Sen's recent discussion of the “conversion handicap” from his general framework of capabilities is highly relevant to the question addressed here.
These concepts, applied with some analytical tools of algebra and geometry, show that Mill's principles can combine with Sen's into a relevant conceptual framework. The central principles and concepts for policy formation on the standard of living for disabled people are not random; they can be specified with clarity.
This paper contributes the relevant conceptual “yardsticks” by which policy for distributing assistance to disabled people can be evaluated. Steps, towards devising better approaches to the distribution of assistance to disabled people can now be taken.

This study conducts a logistic regression analysis of the ability of excess cash and short-term bank loans to substitute for each other and a multiple regression analysis of the factors influencing excess cash and short-term bank loans holdings. In addition, a questionnaire is used to survey the views of Taiwan’s corporate financial leaders on the factors influencing these two liquidity resources. The empirical results support a certain level of substitution between the two types of holdings. The regression analysis shows that for companies that would accumulate more excess cash when interest rates are low, have strong corporate performance, have low debt ratios, and whose chairman of the board and chief executive officer (CEO) are not the same person. Companies tend to have more short-term bank loans when corporate performance is poor, debt ratios are high, and the chairman of the board and CEO are the same person, as well as when the degree of the deviation of control is small. We find that factors on financial structure, operating performance, cost of capital and corporate governance have significant influence on the holdings of these two liquidity facilities in regression, whereas the influence factors exclude corporate governance in questionnaire.

Refutes the suggestion that the mother has the right to remove herself as the life support system from an unborn child. Cites responsibilities in creating the child and argues the child is then seen as a trespasser and is punished by capital punishment.

Portfolios of temporary organisations, particularly portfolios of R&D projects with different project partners, are a common yet understudied phenomenon. We know that these portfolios suffer from tensions inherent in project portfolio ambidexterity (e.g. portfolios balancing R&D projects with new and recurrent partners), yet our understanding of what might lessen these tensions remains limited. This study introduces the idea of project portfolio maturity and theorises how it can mitigate the negative effects of ambidextrous project portfolios. We test our hypotheses by combining proprietary survey and archival data on 136 R&D project portfolios in the German biotechnology industry covering project partnerships with both new and recurrent partners. Our results show that ambidextrous project portfolios hamper firm performance and that portfolio maturity mitigates these negative effects. By introducing a new perspective on project portfolios that accounts for overlooked temporal dimensions, this study provides a new contingency that has the potential to ease the tensions that result from projects with new and recurrent partners. We thereby add to the literatures on temporary organising, project portfolios, and ambidexterity.

A novel frequency domain approach, which combines the pseudo excitation method modified by the authors and multi-domain Fourier transform (PEM-FT), is proposed for analyzing nonstationary random vibration in this paper.
For a structure subjected to a nonstationary random excitation, the closed-form solution of evolutionary power spectral density of the response is derived in frequency domain.
The deterministic process and random process in an evolutionary spectrum are separated effectively using this method during the analysis of nonstationary random vibration of a linear damped system, only modulation function of the system needs to be estimated, which brings about a large saving in computational time.
The method is general and highly flexible as it can deal with various damping types and nonstationary random excitations with different modulation functions.

Studies have examined the influence of knowledge-sharing factors on attitudes and intentions to share knowledge; thus, there is a need to add to the limited research to examine individuals’ actual knowledge-sharing behaviour (KSB). Drawing upon the social cognitive theory (SCT) and transformational leadership, this study aims to develop a new research model which modifies the standard SCT model and augments it with other theories to examine academics’ KSBs.
Questionnaire surveys based on literature and pilot study were conducted with 785 academic staff from four Vietnamese public universities. This study applied structural equation modelling to test the proposed research model and hypotheses.
The findings show that environmental factors (subjective norms, trust) and personal factors (knowledge self-efficacy, enjoyment in helping others) had positive impacts on KSB; KSB had a strongly positive effect on innovative behaviour; and transformational leadership positively moderated the effects of subjective norms, trust and knowledge self-efficacy on KSB. Interestingly, psychological ownership of knowledge was found to have insignificant associations with KSB.
The study findings can be used by university leaders, academic staff and researchers in other similar contexts.
Until now, to the best of the researchers’ knowledge, no studies have applied SCT as a primary lens, in which transformational leadership positioned in a focal behaviour also affected KSB, to investigate research on KSB in organisations, especially in institutions of higher education.
