Much of the existing scholarly works portray institutional voids (IVs) in emerging economies as impeding forces against the development of new ventures. However, little attention has been paid to how such voids generate positive outcomes in emerging market new ventures. Drawing on the institutional theory, we propose IVs as crucial enablers of new venture internationalization. In addition, we investigate both how and when IVs enhance the degree to which new ventures internationalize by examining international learning effort (ILE) as a mediator and two domestic market environmental factors (i.e., environmental dynamism and competitive intensity) as important contingencies. We test our moderated mediation model using primary data gathered from 211 new ventures from Ghana. We found that ILE mediates the relationship between IVs and new venture internationalization and that both environmental dynamism and competitive intensity moderate the indirect relationship between home-country IVs and new venture internationalization. We discuss the theoretical and practical implications of this study.  相似文献

The Marketing Strategy Worksheet is a simple aid to strategic planners. It enables a coherent and integrated plan to be produced and communicated to others. It is a three-level flow chart comprising an analytical stage, formulation of some key primary decisions and subsequent settlement of strategic issues within the marketing mix. The analytical stage incorporates both external and internal analysis. The primary decisions concern company objectives, marketing objectives, demand management, target market and positioning. Using the conventional marketing mix format, decisions are made about product, promotion, distribution and price.  相似文献

This paper numerically examines the size robustness of various conditional moment tests in misspecified tobit and probit models. The misspecifications considered include the incorrect exclusion of regressors, ignored heteroskedasticity and false distributional assumptions. An important feature of the experimental design is that it is based on an existing empirical study and is more realistic than many simulation studies. The tests are seen to have mixed performance depending on both the original null hypothesis being tested and type of misspecification encountered.  相似文献

Summary Advocacy for promoting user participation in the helping processof social work has been reported in the literature since the1970s, but the practicality of the concept for different clientelesof social work has been rarely explored. This paper presentsa recent qualitative study on exploring the applicability ofuser participation in work with high-risk youth in the streetswho are usually regarded as immature and low in both self-confidenceand the ability to make the ‘right’ decisions. Thefindings of the study support the promotion of the concept ofuser participation in working with high-risk youth. Positivechanges and growth were observed among this group with the applicationof user participation in the helping process. Ways for promotingthe implementation of this concept in work with high-risk youthare suggested.  相似文献

Rivers are important components of many urban systems, and research into urban rivers is increasing internationally, both in scope and intensity. As an introduction to a special section on urban rivers, this short article briefly highlights some key trends in urban river research based on a survey of published articles from Web of Knowledge, before summarising the contributions made by the special section papers. In particular, there has been a general increase in work on urban rivers since the 1990s, with a more dramatic increase from 2001. Most published research has concentrated on water quality and its wider environmental implications; ecologically, many studies have focused on autecology, community ecology or river restoration/rehabilitation, with the main emphasis on macroinvertebrates or fish. Geographically, most studies have taken place in North America (mainly the US) and Asia (mainly China). In the large majority of cases research has been on relatively small rivers within urbanised catchments rather than large, heavily urbanised systems within major towns or cities. Given the wide range of topics and studies relating to urban river research, a detailed meta-analysis of the urban river ecology literature would be a useful endeavour. The six papers included in the special section of this issue provide a sample of some of key and emerging themes within recent urban river research, and originate from a session on the understanding and management of urban rivers held at the Royal Geographical Society (with IBG) Annual Meeting in 2010, at Imperial College London.  相似文献
