  • Are nonprofits (NPOs) exhibiting the brand orientation believed to be critical to successful outcomes? To answer this question, we investigate the brand orientation and brand management of the Young Men's Christian Association (YMCA), American Red Cross (ARC), and The Salvation Army to assess the implementation of brand concepts in two different locations within the USA compared to each agency's central body. Despite the support of some propositions, there exists inconsistent evidence of strong brand management in the organizations studied. The variation of brand visuals, missions, and taglines indicates that good structure, policy, and guidelines are not enough. There must be true brand orientation, which includes oversight of consistent application of all brand constructs to achieve organizational goals. This study provides a framework upon which future in‐depth empirical research may be based. The authors outline these next steps as a foundation for enhancing the study and practice of brand management in NPOs.

This study explores the specific conditions under which key strategic alliances of small and medium‐sized enterprises (SMEs) with commercial partners can become multiplex in knowledge exchange. Using survey data from a sample of 150 Spanish SMEs in the information and communication technology (ICT) industry, we find that trust creates an appropriate context for the concurrent acquisition of technological, market, and managerial knowledge. When the SME and its key commercial partner exhibit significant strategic, technological, and market differences, however, the SME's ability to acquire different types of knowledge diminishes considerably, reducing the positive impact of trust on knowledge multiplexity.  相似文献

Contemporary organizations often reciprocate to society for using resources and for affecting stakeholders by engaging in corporate social responsibility (CSR). It has been shown that CSR has a positive impact on employee attitudes. However, not all employees may react equally strongly to CSR practices. Based on socio-emotional selectivity theory (Carstensen in Science 312:1913–1915, 2006), we contend that the effect of CSR on employee satisfaction will be more pronounced for older than for younger employees, because CSR practices address those emotional needs and goals that are prioritized when people’s future time perspective decreases. In one multi-source field study (N = 143) and one experimental study (N = 500), we demonstrate that CSR indeed has a stronger positive effect on employee satisfaction for older relative to younger employees. Accordingly, engaging in CSR can be an attractive tool for organizations that aim to keep their aging workforce satisfied with their job.  相似文献

A substantial proportion of foodborne illness is associated with food prepared in households. The primary understanding of how foods are handled in private homes comes mostly from questionnaire based studies and direct observation. The aim of this survey was to examine consumers' perceptions and knowledge of safe food handling practices in Greece. More specifically, their attitudes, opinions and self‐reported practices were studied. Data were collected from a total of 399 consumers living in Greece by the use of a self‐administered on‐line survey. The questionnaire consisted of four positive and five negative statements according to the 5‐point Likert scale, which grouped into three constructions using principal component analysis in order to investigate food safety perceptions of consumers. Furthermore, the survey included 11 demographic questions, two close‐ended questions (type yes/no) and four questions that are related to self‐reported food‐handling practices. The results showed that the most commonly known bacterium causing food‐related illness according to respondents' knowledge is Salmonella (99.7%), followed by Escherichia coli (73.9%) and Listeria (58.4%). The overall consumers' score concerning food safety was 32.8 ± 5.37 (full score was 45). No significant differences to the mean score of food safety knowledge were found according to gender, age or the incidence of foodborne illness over the past 12 months. Knowledge and awareness of safe food handling practices was enhanced at higher education levels, while homemakers were found to have deficiencies at this level. Information obtained from consumers can be used to shape educational programs and determine where food safety educational efforts would be most effective and the needed content of the messages.  相似文献

We systematically investigate the links between the digit ratio (2D:4D)—a biomarker for prenatal testosterone exposure—and two measures of individual risk taking: (i) risk preferences (RP) over lotteries with real monetary incentives and (ii) self‐reported risk attitude (RA). We find that both the right‐hand and the left‐hand digit ratio are significantly associated with RP: Subjects with lower digit ratios tend to choose riskier lotteries. Neither digit ratio, however, is associated with self‐reported RA.  相似文献

Directors’ personal attributes have significant impacts on governance effectiveness. We study whether directors’ accounting expertise affects corporate financial policy and investigate dividend in specific. We construct a dataset of audit committee directors’ accounting expertise for Standard & Poor 500 firms from 2005 to 2012. We first verify directors’ monitoring roles by showing that firms with accounting expert sitting on their audit committees demonstrate stronger accounting conservatism. In our main tests, we find that these firms maintain lower dividend payment level, which are less sensitive to earnings volatility. This suggests directors’ advisory roles in financial policy. We further show that our accounting expertise cannot be subsumed by management ability. In additional test, we further examine the baseline results conditional on analyst forecast error. Our findings highlight the importance of directors’ professional expertise in fulfilling their governance roles.  相似文献

As the world economy has undergone various changes and shocks, the oil market went through significant fluctuations during the period 1994–2015. This study focuses on discussing the possible factors that determine crude oil prices, which include world economic growth, market power of Organization of the Petroleum Exporting Countries (OPEC), non‐OPEC supply and the value of dollar, taking into account the structural changes that influence the study period, which is quarterly data for the period of 1994.Q1–2015.Q3. For time series stationarity tests, Zivot and Andrews (1992) and Perron (1997) unit root test with structural break is used. To test the existence of a long relationship in the presence of structural changes, the Gregory and Hansen (1996a, 1996b) method of co‐integration is used. For long‐run coefficient, we proceed to estimate fully modified least squares. The result shows a significant influence of non‐OPEC supply, the dollar appreciation and world gross domestic product growth, but OPEC did not have a significant effect on the price of oil, which is indicated by the structural break for OPEC capacity utilisation at 2002.Q1, that indicates the starting point of the loss of OPEC power. Establishing the presence of co‐integration, we apply the evaluation of Granger causality for co‐integrated data, using vector error‐correction model.  相似文献
