A study of personal computer utilization by managers

Personal computer (PC) utilization has become an important concern due to the PC's widespread and rapid implementation in the work place. A field study evaluated the responses of 105 managers who were PC users. The research model viewed PC utilization as a function of organizational, personal, computer system, and process attributes. Analysis was performed using Pearson correlations and one-way analysis of variance. The two items with the strongest and most consistent correlation with reported computer use time were user satisfaction with (1) the computer system's contribution to job performance and (2) their level of competence with the system. These findings suggest that PC utilization can be interpreted as a function of its perceived costs and benefits.     

Future buildings and their services

The authors explore strategic issues in briefing, design and operation of buildings and their services. Feedback from post-occupancy surveys suggests a need for better integration, less complication, and robust rather than optimum performance, with a concentration on ends rather than means. Emphasis must be given to usability, manageability and minimizing downside risks. Les auteurs examinent des questions strategiques liees a l'information, la conception et l'exploitation de batiments et de leurs services. Les informations extraites d'enquetes menees aupres d'anciens occupants font ressortir la necessite d'une meilleure integration, d'une simplification et de caracteristiques d'exploitation solides plutot qu'optimales, avec une concentration sur la fin plutot que sur les moyens. L'accent doit etre mis sur les facilites d'utilisation et de gestion et sur une minimisation des risques.     

An empirical analysis of open source software developers’ motivations and continuance intentions

We investigated open source software (OSS) developers’ intentions to continue their involvement in future projects. The research goal was to analyze the motivations of OSS developers systematically and identify those factors that influenced their continuation. A work motivation model for OSS developers was proposed and a research model was empirically validated using data from a field survey of 148 OSS participants. The results showed that OSS developers’ feelings of satisfaction and their intentions to continue with OSS development was influenced by both helping behavior and economic incentives and also that adequate motivators existed, though OSS developers did not benefit equally and there was substantial room to improve their experiences as OSS developers.     

An empirical analysis of the antecedents of web-based learning continuance

Like any other product, service and Web-based application, the success of Web-based learning depends largely on learners’ satisfaction and other factors that will eventually increase learners’ intention to continue using it. This paper integrates the concept of subjective task value and fairness theory to construct a model for investigating the motivations behind learners’ intention to continue using Web-based learning. The model theorizes that four components of subjective task value (i.e., attainment, utility, intrinsic, and cost) and three dimensions of fairness (i.e., distributive, procedural, and interactional) affect learners’ satisfaction. We also argue that satisfaction and four distinct components of subjective task value influence learners’ intention to continue using Web-based learning. The hypothesized model is validated empirically using data collected from 202 learners of a Web-based learning program designed for continuing education. The results showed that attainment value, utility value, intrinsic value, distributive fairness, and interactional fairness exhibited significant positive effects on satisfaction. Utility value and satisfaction play significant roles in shaping learners’ intention to continue using Web-based learning.

Measurement Equivalence of the German Job Satisfaction Survey Used in a Multinational Organization: Implications of Schwartz's Culture Model.

The authors tested measurement equivalence of the German Job Satisfaction Survey (GJSS) using structural equation modeling methodology. Employees from 18 countries and areas provided data on 5 job satisfaction facets. The effects of language and culture on measurement equivalence were examined. A cultural distance hypothesis, based on S. H. Schwartz's (1999) theory, was tested with 4 cultural groups: West Europe, English speaking, Latin America, and Far East. Findings indicated the robustness of the GJSS in terms of measurement equivalence across countries. The survey maintained high transportability across countries speaking the same language and countries sharing similar cultural backgrounds. Consistent with Schwartz's model, a cultural distance effect on scale transportability among scales used in maximally dissimilar cultures was detected. Scales used in the West Europe group showed greater equivalence to scales used in the English-speaking and Latin America groups than scales used in the Far East group.

Identifying associations between mobile social media users’ perceived values,attitude, satisfaction,and eWOM engagement: The moderating role of affective factors

Recently, the explosive growth of mobile social media technologies has dramatically transformed individuals’ interpersonal interaction, decision-making, and daily lifestyles. The primary objectives of this current article are to investigate the possible influences of perceived values (hedonic and utilitarian) on WeChat users’ affective responses (attitude and satisfaction) and electronic word-of-mouth (eWOM) engagement. This study represents one of the few that utilized customer-perceived value theory and uses and gratifications theory to establish a conceptual framework to determine consumers’ word-of-mouth behaviors in the WeChat setting. Based on a web-based survey of 408 WeChat users, structure equation modeling was implemented to identify and confirm the hypothesized research model. Overall, the results reveal that hedonic value and utilitarian value positively and significantly impact WeChat users’ attitudes and anticipated satisfaction. Additionally, satisfaction has a significant influence on eWOM engagement. Furthermore, utilitarian value is discovered to exert a significant indirect effect through satisfaction on eWOM engagement. The obtained outcomes offer fresh insight into whether and how mobile social media could promote mobile social media users’ attitudes and gratification which subsequently would facilitate indicators of eWOM engagement in contemporary mobile-mediated context.     

A self-adaptable query allocation framework for distributed information systems

In large-scale distributed information systems, where participants are autonomous and have special interests for some queries, query allocation is a challenge. Much work in this context has focused on distributing queries among providers in a way that maximizes overall performance (typically throughput and response time). However, preserving the participants’ interests is also important. In this paper, we make the following contributions. First, we provide a model to define the participants’ perception of the system regarding their interests and propose measures to evaluate the quality of query allocation methods. Then, we propose a framework for query allocation called Satisfaction-based Query Load Balancing (SQLB, for short), which dynamically trades consumers’ interests for providers’ interests based on their satisfaction. Finally, we compare SQLB, through experimentation, with two important baseline query allocation methods, namely Capacity based and Mariposa-like. The results demonstrate that SQLB yields high efficiency while satisfying the participants’ interests and significantly outperforms the baseline methods.
