This article analyzes the managing of high-tech projects in complex and dynamic settings. Building on recent developments in organization theory and knowledge management, we focus on the importance of understanding the ways in which project-centered activities are shaped in time and space, both in the organization itself and in a wider context embracing customers, consultants and suppliers. A longitudinal case study including semi-structured interviews, observations and secondary data will substantiate our findings. The study offers both theoretical and practical insights suggesting that projects are exposed to a varying degree of complexity and dynamics, calling for different managerial approaches. The analysis shows that boundary spanning has many dimensions that have to be considered in the management of projects in space and time. The article concludes by suggesting seven analytical categories for analyzing and understanding projects in their spatial and temporal contexts.  相似文献

Over the last decade, markets for investments have changed in Europe. Consumers have become more aware of ethical standards and violations of social values and norms. While in some countries, such as the United States, this change took place decades ago, the market for ethical investment in Europe is still at an early stage. The present study investigates the underlying motives for ethical assets of consumers in early-stage markets. Using seven interviews with financial experts and five focus groups with ethical and conventional investors, we examine how investors view ethical investment, how ethical investors are described in terms of socio-demographics and personality characteristics, and which attitudinal factors are related to ethical investment behaviour. Interviews and focus groups are recorded and qualitatively analysed according to grounded theory. Ethical investment is found to be characterised through negative and positive ethical criteria. Our findings demonstrate how essential it is for ethical investors to lead a certain lifestyle driven by particular ecological and social values. Attitude theory serves to explain ethical investment behaviour. Conclusions for the marketing of ethical investment funds and for future research are drawn.  相似文献

Limited extant experimental research on advertising appeal effectiveness in the presence of price cues in a service offer provides the motivation for this study. While past research has found support for the effectiveness of both rational and emotional appeals in services marketing, this research, in the context of hotel advertising, shows that appeal type effectiveness may vary with the price level of the service. More specifically, this study finds that rational appeals are more effective than emotional appeals for low-priced hotels, but for high-priced hotels, rational and emotional appeals show no significant difference in influencing consumer evaluations of the offer.  相似文献

Unlike the large literature on ‘democracy and trade’, there is a much smaller literature on the effect of the level of democracy in a nation on the level of its foreign direct investment (FDI) inflow. These few studies reveal mixed empirical results, and surprisingly only one study has examined bilateral FDI flows. Moreover, few of these studies use multiple governance indicators separating the ‘pluralism’ effect of democratic institutions from the ‘good governance’ effect, there are no studies on democratic institutions’ various effects on the level of FDI relative to trade, and there are no studies of democratic institutions’ various effects on the selection of countries into FDI. We focus on three contributions. First, we examine the simultaneous effects of the World Bank's (six) Worldwide Governance Indicators (WGIs) – which allow separating the effects of pluralism from those of five other good governance measures – on bilateral trade, FDI and FDI relative to trade using state‐of‐the‐art gravity specifications. Second, we find strong evidence that – after accounting for host governments’ effectiveness in various roles of good governance – a higher level of pluralism as measured by the WGIs’ Voice and Accountability Index reduces trade levels, likely by increasing the ‘voice’ of more protectionist less‐skilled workers, but not FDI levels. Moreover, we find qualitatively different effects of other WGIs – such as political stability – on trade versus FDI flows. Third, we account for firm heterogeneity alongside a large number of zeros in bilateral FDI flows using recent advances in gravity modelling. We distinguish between the (country) intensive and extensive margins and show that pluralism affects FDI inflows negatively at the intensive margin, but positively at the extensive margin.  相似文献

One of the strategies employed by companies to differentiate themselves from others, in the food market, has been to market organic products according to the assumption that environmental values are an important influence on people's behavior. However, studies of the behavior of organic food consumers show that there is some debate on this subject. Although some studies associate organic food consumption with motives and attitudes in which the environment plays a predominant role, a greater number conclude that the motives for consuming this type of food are basically egoistic (related to health, food safety, or the quality or flavor of the food). This can lead to problems in deciding the central thrust of the marketing strategy. The purpose of this paper is to analyze the meaning and interpretations placed on the term “organic,” and how they are integrated, as a way to explain consumption behavior. Qualitative research methods were adopted for this purpose. Four focus group sessions with different sociodemographic profiles, held in the cities of Madrid and Seville, in Spain, displayed two evident paradoxes, which could indicate that environmental motives are not important for consumers in this market. It is concluded that the term “organic” plays an important role as a heuristic cue to superiority, irrespective of the consumer's knowledge about the real features of organic food. Three alternative models are presented to explain consumer behavior. These results could be useful to food companies, largely in connection with positioning this type of product and with their communications policy.  相似文献

We study the determinants of share repurchases and dividends in Finland. We find that higher foreign ownership serves as a determinant of share repurchases and suggest that this is explained by the different tax treatment of foreign and domestic investors. Further, we also find support for the signalling and agency cost hypotheses for cash distributions. The fact that 41% of the option programmes in our sample are dividend protected allows us to test more directly the ‘substitution/managerial wealth’ hypothesis for the choice of distribution method. When options are dividend protected, the relationship between dividend distributions and the scope of the options programme turns to a significantly positive one instead of the negative one documented in US data.  相似文献

Managers can improve real risk‐adjusted firm performance by matching nominal assets with nominal liabilities, thereby reducing the sensitivity of real risk‐adjusted returns to unexpected inflation. The net asset value of US equity real estate investment trusts (REITs) serves as a good proxy for nominal assets and, accordingly, we use a sample of US REITs to test our hypothesis. We find that for the firms in our sample: (i) their real risk‐adjusted performance, and (ii) their inflation‐hedging qualities are inversely related to deviations from this ‘matching‐nominals’ argument. In addition to providing managers with a vehicle to maximize real risk‐adjusted performance, our findings also provide investors with the tools to infer inflation‐hedging qualities of equity investments.  相似文献

A wealth of research in the past decades has examined born globals or international new ventures, which are firms that from inception view the whole world as a market and as a source to access resources. Many of these firms build their competitive advantage on high-tech knowledge. However, although many studies have shown how born globals can achieve success if they access resources through their relationships from actors in their networks, few studies have explored the relationship between born globals and universities. Universities are important actors in creating new technology knowledge, and many studies have shown how new firms, or so-called university spin-offs (USOs), are formed around universities. The current study explores why some USOs are successful in their international growth strategy and discusses the factors that influence and facilitate the internationalization process. The study investigates 10 USOs around the newly established Halmstad University in Sweden and finds that universities have a positive effect on firm creation and initial international growth. The regional competence base increases from the establishment of a local university, primarily by strengthening the regional human capital and by increasing university research. This study shows that researcher entrepreneurs’ ventures start as born globals, but that these firms do not continue to grow. Born global business models, per se, do not lead to competitive advantage and successful internationalization. Instead, a strategy built on customer focus and an ability to adapt to different customer demands lead to growth, and the location of growth is dependent on the size of the home market. This study also shows that student entrepreneurship can be a successful growth strategy for USOs focusing on both international and local markets.  相似文献

This study examined the ways in which perceived constraints and self-efficacies associated with participation in active recreation influenced Hong Kong and Australian university students' interest, intention, and participation in regular active recreation. The study indicated that perceived constraints have weak negative effects whereas self-efficacies have stronger positive effects on students' interest, intention, and participation in regular active recreation. Time efficacy, persistence efficacy, and activity efficacy emerged as important indirect motivators of active recreation engagement. The influences of constraints and self-efficacies on active recreation participation mainly occurred indirectly through adjustments in participation interest and intention.  相似文献
