We study the distribution of basic scientific research across countries and time, and explain the process that resulted in
the United States becoming the undisputed leader in basic research. Our study is based on the records of scientific awards,
and on the data of global economic trends. We investigate the degree to which scale/threshold effects account for the number
of prizes won. We constructed a stylized model, predicting a non-linear relationship with lagged relative GDP as an important
explanatory variable of a country’s share of prizes. Our empirical research findings find support for these predictions and
the presence of a “winner-takes-all” effect.

ABSTRACTThe purpose of this article is to propose and test a model in order to better understand brand equity. The goal of this research is to identify the drivers and determine how they influence brand equity performance in the researched industry in order to develop a more effective brand strategy. Quantitative data collected are used to test a model of brand value in the context of the food industry. The findings of this research provided evidence that the customer-based brand equity model can be applied to the food industry context and be used to guide marketing activities internationally. Brand awareness has a positive influence on brand associations and perceived quality. Brand associations have a positive influence on brand loyalty. Finally, brand loyalty, perceived quality, and brand associations all have a positive effect on brand equity. This study contributes to the scarce international brand equity literature by testing the proposed model using data from a sample of consumers in two European countries. 相似文献

Computer software can easily produce many financial models with technical skill, but investigators need to interpret and adapt computer output. Such analysis requires a deep knowledge of scientific fundamentals. We argue that an evidential perspective is more appropriate than a decision framework for model selection. We discuss four necessary conditions for any scientific investigation: observables, interpretables, replicables, and robustness in the context of examples familiar to finance professionals. Carefully planning the design of an experiment is the best way to address many econometric maladies. Furthermore, we emphasize the need for more sensitivity testing and for independent replication of empirical results within the finance profession. 相似文献

AbstractAims: This trial-based economic evaluation (EE) assesses from a societal perspective the cost-effectiveness of an intensive 3-day cognitive theory-based intervention (CDT), compared to care-as-usual, in patients with relapsing remitting multiple sclerosis (RRMS) and low disability (Expanded Disability Status Scale [EDDS] score < 4.0).Materials and methods: The trial of the EE was registered in the Dutch Trial Register: Trial NL5158 (NTR5298). The incremental cost-effectiveness ratio (ICER) was expressed in cost on the Control sub-scale of the Multiple Sclerosis Self-Efficacy Scale (MSSES) and the incremental cost-utility ratio (ICUR) in the cost per Quality Adjusted Life Years (QALY) using the EQ-5D-5L. Bootstrap, sensitivity, and sub-group analyses were performed to determine the robustness of the findings.Results: The two groups of 79 patients were similar in baseline characteristics. The base case ICER is situated in the northeast quadrant (€72 (40.74/€2,948)) due to a higher MSSES Control score and higher societal costs in the CDT group. The ICUR is situated in the northwest (inferior) quadrant due to losses in QALY and higher societal costs for the CDT group (?0.02/€2,948). Overall, bootstrap, sensitivity, and sub-group analyses confirm the base case findings. However, when the SF-6D is used as a study outcome, there is a high probability that the ICUR is situated in the northeast quadrant.Limitations: The relative short follow-up time (6?months) and the unexpected increase in MSSES Control in the control group.Conclusions: When using the EQ-5D-5L to calculate a QALY, CDT is not a cost-effective alternative in comparison to care as usual. However, when using self-efficacy or SF-6D as outcomes, there is a probability that CDT is cost-effective. Based on the current results, CDT for patients with RRMS clearly show its potential. However, an extended follow-up for the economic evaluation is warranted before a final decision on implementation can be made. 相似文献

Two-thirds of the world's population lives in poverty, a global problem that researchers from a wide variety of disciplines study. Yet there is a fundamental lack of service research pertaining to this huge segment of society, commonly known as the base of the pyramid. This segment offers a rich source of information that could help break new ground in service research, by exploring services in contexts in which its current concepts, models, theories, and generalizations might not apply the same way. This article starts by exploring key contributions in base of the pyramid literature and identifying the main perspectives from which extant knowledge has developed. By revising existing service research priorities to identify useful intersections with base of the pyramid perspectives, this study offers new grounds deriving five research streams that reflect the integration of base of the pyramid research perspectives with service research priorities. Finally, this article details the emerging area of base of the pyramid service research using one of those research priorities, namely, transformative service research, in an effort to specify the relevant objectives, scopes, differences, and similarities and thereby identify common grounds for future service research at the base of the pyramid. 相似文献

ABSTRACT We undertook a review and classification of research on electronic commerce (e-commerce) in developing countries. We analyzed 181 articles published in a broad range of journals covering e-commerce, global information technology, and development issues. The analysis provides a roadmap that not only indicates the current state of e-commerce for development research but also identifies gaps and priorities for future research. This will be of significant value to both academics and practitioners who are working on, or plan to work on, e-commerce in developing countries. 相似文献
