Research shows that, under certain circumstances, people using GSS can be substantially more productive than people who do not. However GSS has been slow to transition into the workplace. This paper argues that the Technology Transition Model (TTM) may be a useful way to explain this seeming paradox. The paper presents a case study of GSS transition in two organizations – one where a self-sustaining and growing community of users emerged, and one where it did not. Following TTM, it explores the frequency with which users perceived cognitive, economic, affective, political, social, and physical value from using the system. Comparison of the cases reveals differences in perceptions of value along several of these dimensions that are consistent with TTM. The findings suggest the model may be a useful way to explain the transition of collaboration technology, but more research will be required to test the model more rigorously.  相似文献

Experimental analysis of choice   总被引:2,自引:1,他引:2  
Experimental choice analysis continues to attract academic and applied attention. We review what is known about the design, conduct, analysis, and use of data from choice experiments, and indicate gaps in current knowledge that should be addressed in future research. Design strategies consistent with probabilistic models of choice process and the parallels between choice experiments and real markets are considered. Additionally, we address the issues of reliability and validity. Progress has been made in accounting for differences in reliability, but more research is needed to determine which experiments and response procedures will consistently produce more reliable data for various problems.Sawtooth SoftwareDecision Research  相似文献

We examine the relative roles of marketing actions and product quality in determining commercial success. Using the motion picture context, in which product quality is difficult for consumers to anticipate and information on product success is available for different points in time, we model the effects of studio actions and movie quality on a movie’s sales during different phases of its theatrical run. For a sample of 331 recent motion pictures, structural equation modeling demonstrates that studio actions primarily influence early box office results, whereas movie quality influences both short- and long-term theatrical outcomes. The core results are robust across moderating conditions. We identify two data segments with follow-up latent class regressions and explore the degree of studio actions needed to “save” movies of varying quality. We finally offer some implications for research and management.  相似文献

This paper examines the after-market for initial public offerings (IPOs), particularly the security valuation effects of structural differences in available information. There is a diversity of information among issuing firms at the time of their offering and particularly under certain market conditions. Because this diversity decreases with time and after-market trading, the IPO market provides an ideal setting for testing errors due to differential information levels in early after-market valuation of IPO firms. We find evidence that during “hot” market conditions and for firms characterized by low levels of available information, the market values of issuing firms are more likely to be overestimated in the immediate after-market. We also find positive overestimation of market values to be more likely for larger IPOs and for those marketed by the less prestigious underwriters.  相似文献

Economic activities of families have important influences on processes of family development and family change over time. Knowledge of these special relations has expanded in recent years, as has the literature on the economics of family life as a general field. As a result, scholars and professionals in consumer studies and home economics need conceptual frameworks that organize areas of specific findings and identify specific issues for research. A conceptual framework which identifies four economic activities performed by families and six fundamental family development and family change processes is proposed. Then, a matrix of testable hypotheses is formulated, emphasizing economic activities as independent variables in family development and change. The matrix portrays the central roles economic influences play in contemporary family life, and suggests a complete, holistic understanding of these influences. The matrix also provides a conceptual guide to the design of empirical research and synthesis of findings on the economics–family development interface.  相似文献

Company–community agreements are widely considered to be a practical mechanism for recognising the rights, needs and priorities of peoples impacted by mining, for managing impacts and ensuring that mining-derived benefits are shared. The use and application of company–community agreements is increasing globally. Notwithstanding the utility of these agreements, the gender dimensions of agreement processes in mining have rarely been studied. Prior research on women and mining demonstrates that women are often more adversely impacted by mining than men, and face greater challenges in accessing development opportunities that mining can bring. Nonetheless, there is currently little guidance for companies, government or communities in bringing a gender perspective to the fore in mining and agreement processes. It is undisputed in human development literature that investment in women and sensitivity to gender delivers long-term health, education and local development outcomes. In mining and development, a number of key factors remain unexplored. These include: women’s participation in agreement processes, the gendered distribution of agreement benefits, and the extent to which impacts and benefits influence women’s development and economic inclusion. This paper presents the results of the first phase of an applied research project undertaken by the Centre for Social Responsibility in Mining (CSRM) at The University of Queensland and funded by the Minerals Council of Australia (MCA) and the Department of Foreign Affairs and Trade (DFAT). The project sought to connect with experienced practitioners who had been directly involved in mining and agreement processes to document and analyse grounded perspectives on gender dynamics and agreements, and connect those experiences with the broader literature. Findings from this study have implications for the role of mining companies and governments in promoting gender equality and empowerment as part of their commitments to sustainable development. They also have implications for community groups and their representatives in terms of how they might engage in agreement processes to maximise women’s participation and influence. In many social contexts, a key challenge will be navigating the territory of cultural norms and gender equality, particularly in cultures where women’s influence in the public sphere is not strong. The authors argue that without consideration of a gender perspective, including gender’s intersection with other factors such as class, race, poverty level, ethnic group and age, mining agreements will not be inclusive, may exacerbate gender inequalities, and fail to contribute to long-term sustainable development.  相似文献

This article considers the neglected legacies of the Lancashirecotton industry and their impact on the U.K. outdoor trade.Studies of the decline of the Lancashire cotton industry afterthe Second World War have concentrated on the collapse of coarsecotton spinning and weaving, largely ignoring the impact ofthe knowledge and skills related to the finishing trades. Theexamination of the evolution of rainwear, coatings, and high-performancefabrics in the nineteenth century provides a backdrop to a studyof the innovation process that emerged in the U.K. outdoor tradeafter 1960. It shows that there was a path dependency betweenthe skills that resided in Lancashire’s finishing tradesand coating and fabric innovation for outdoor products. Thisarticle explores both the legacy and the ways in which the networksof innovation functioned as the U.K. outdoor trade expanded.  相似文献

Modeling Methods for Discrete Choice Analysis   总被引:2,自引:3,他引:2  
This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.  相似文献
