Article impact is becoming an increasingly popular metric for assessing a scholar's influence, yet little is known about its properties or the factors that affect it. This study tests whether author, article, and methodological attributes influence the impact of SMJ articles, defined as summed counts of article citations. Findings reveal that authors having fewer, more‐often cited articles tended to have SMJ articles that received the most citations. In addition, whether an article appears in a regular or a special issue is not a stable predictor of its impact. Moreover, empirical articles that test primary data, control for more threats to internal validity, and have higher statistical power tend to receive more citations. Further, an article's long‐term impact oftentimes becomes apparent shortly after its publication. Overall, the findings provide new insights into the determinants of impact and its temporal qualities and help explain some of the differences between high and average impact articles. The findings also underscore the need for transparency between author publication strategies (article volume, impact) and the requirements of his/her institution. Implications for authors, reviewers, editors, and administrative evaluation are offered. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

The paper presents an analysis of the effects of televised alcohol beverage advertising on the consumption of alcohol among a sample of US teenagers. While no effects of exposure on total consumption are demonstrated for the total sample, consistent with other research on alcohol advertising effects, the present analysis reveals the importance of ‘orientations towards advertising’ as linkages between exposure and consumption behaviour. Specifically, a social utility orientation, involving learning of normative expectations about drinking, and a vicarious utility orientation, involving identification with models in alcohol beverage commercials, are shown to be mediating factors which condition the effects of advertising exposure.

This paper proposes that customers often respond to brand extension concepts by visualizing the product. We call this process spontaneous visualization and suggest that it precedes concept evaluations. In two studies, we show that spontaneous visualization is enhanced by the fit between the parent brand and the extension category and by the ease with which the product category can be imagined. The appeal of the visualized image in turn determines whether visualization enhances or decreases concept evaluations. In addition, we find a stronger link between product evaluations and delayed choice when evaluations are based on visualization; evaluations based on visualization hence appear to be more “valid” in the sense of predicting subsequent behavior. Implications of these findings and ideas for future research are discussed.

Democracy, foreign direct investment and natural resources   总被引:1,自引:0,他引:1  
Empirical studies that examine the impact of democracy on foreign direct investment (FDI) assume that the relationship between democracy and FDI is the same for resource exporting and non-resource exporting countries. This paper examines whether natural resources in host countries alter this relationship. We estimate a linear dynamic panel-data model using data from 112 developing countries over the period 1982-2007. We find that democracy promotes FDI if and only if the value of the share of minerals and oil in total exports is less than some critical value. We identify 90 countries where an expansion of democracy may enhance FDI and 22 countries where an increase in democratization may reduce FDI. We also find that the effect of democracy on FDI depends on the size and not the type of natural resources.  相似文献

New organizing factors are emerging as human resources professionals seek performance breakthroughs, with process and competency emerging as key factors in determining how the HR function is organized. While the process focus rides the wave of interest in total quality management and reengineering, a growing number of organizations see competence as the key to enduring performance and to making HR most effective. This article combines experience from the authors' work with some emerging possibilities to describe a competency-based approach for designing a high performing HR organization. © 1996 by John Wiley & Sons, Inc.  相似文献

Alternative land management practices, including agroforestry, help to maintain levels of soil organic matter (SOM) and can facilitate soil carbon (C) sequestration for mitigating atmospheric CO2 emissions. This study quantified C inputs and determined the changes of the soil C pool in a 19-year-old Gliricidia sepium alley cropping system, studied at two fertiliser levels (tree prunings only [? N], and tree prunings plus chicken manure [+ N]), and was compared to a sole crop system. Carbon input from tree prunings ranged from 455 to 457 g C m? 2 y? 1, whereas C inputs from crop residues were similar between alley- and sole crops ranging from 121 to 159 g C m? 2y? 1. The soil organic C (SOC) pool in the alley crop was 16–23% higher than the sole crop. In the 19th year of alley farming, SOC was significantly higher (p < 0.05) in the alley crop (3.2%) compared to the sole crop (2.4%), and was also greater compared to that at the time of establishment of the agroforestry system (2.8%). Gross SOC turnover to a 20-cm depth ranged from 12 to 14 years in the + N and ?N alley crops compared to 49 and 50 years in the + N and ?N treatments for the sole crops. Residue stabilisation efficiency in the alley crops was 39% and 55% in + N and ?N treatments respectively.  相似文献

Preparing qualified graduates for the tourism and hospitality industry who will stay and achieve promotional success is paramount. The objectives of this research project were to determine promotional advancement expectations and strategies to improve promotional opportunities. Two separate questionnaires, with both open and close-ended questions, were sent to upper classmen/women in hospitality and tourism programs and alumni of the same programs. In total, 717 (409 students and 308 alumni) completed the questionnaires. Chi-square tests were run to determine differences between student and alumni responses. To assist in analysis of open-ended responses, Atlas.ti was used. There was a statistically significant difference between students and alumni responses in regards to promotional expectations; students expected it to take a significantly longer time to receive a promotion to supervisor or manager than alumni. Overall, students and alumni indicated strategies such as more real-world-focused courses with hands-on experiences.  相似文献

Intermediaries play a crucial role in the functioning of agricultural and food markets in developing countries through linking production, imports and storage with consumption. We analyse how competition in the intermediary sector and alternative forms of intermediaries determine the incentives for storage and market outcomes more generally. We apply this framework to the Egyptian wheat sector as an illustrative case study, a country where food security is a priority, where both forms of intermediaries co-exist and undertake storage but where issues of reforms to the role of intermediaries have been raised. Through stochastic simulation, we analyse two changes in government policy: first, the effects of changing the policy instruments with both types of intermediaries undertaking storage; second, relating to market reforms where the private sector replaces the storage function of the parastatal. These issues have wider significance for addressing the interaction between food security and a wide range of policy reforms including de-regulation of parastatals in developing countries.  相似文献
