Competencies: Alternative frameworks for competitive advantage

Competencies in organizations can be broadly classified as employee-level and organizational-level. Since organizational-level competencies are embedded in employee-level competencies, the identification of the latter is important for organizations interested in using competencies to achieve competitive advantage. In this paper, we present a model of employee competencies as a means to organizational competitiveness and discuss various frameworks for identifying employee competencies. In addition to the traditional frameworks, which are more suitable for organizations functioning in a static environment, we offer two alternative frameworks that can be useful in identifying competencies in a dynamic organizational environment. Once appropriate employee-level competencies are identified, a competency-based human resource system can be implemented to ensure that employees actually do possess the identified competencies.     

Can Arabic Proverbs Enhance Arabic-Speaking Students’ Comprehension of Financial Concepts?: An Empirical Study in Randomly Selected Business Schools in Dubai

In this study, we investigated the use of Arabic proverbs and quotes for teaching finance courses to Arabic-speaking students who are nonnative speakers of English. The study found that the use of Arabic proverbs and quotes greatly enhances the students’ comprehension of the finance topics covered. Similarly, the study revealed that the use of Arabic proverbs and quotes for Arabic-speaking students in teaching finance courses creates rapport between the student and instructor, thus enhancing learning. Finally, the study confirmed that the use of Arabic proverbs and quotes for Arabic-speaking students in teaching finance courses does not lead to confusion or complicate matters, but enhances comprehension and bolsters retention.     

Construct validation of an Arabic version of the Learning Transfer System Inventory for use in Jordan

The purpose of this study was to translate and validate an Arabic version of the Learning Transfer System Inventory (LTSI) for use in Jordan. The study also investigated the perceptions of transfer system characteristics across selected individual and situational variables. The LTSI was administered to 450 employees of 28 different public and private sector organizations operating in Jordan. Principal axis factoring with oblique rotation was used to uncover the underlying structure of the Arabic version of the LTSI. Results showed a latent factor structure that is highly consistent with the English version of the LTSI. Results also indicated that transfer system perceptions differed across levels of education, years of experience, types of training, choice of training, sector of the organization and task of the organization. Implications for the field of human resource development are also provided.     

信息化进程中的组织变革与IT治理

信息技术对组织的技术性嵌入,改变了组织的内部与外部环境,若要使组织的信息化取得预期的效果,组织的变革是必需的。传统的理论认为,这种变革必然导致组织架构的扁平化、分散化及柔性化。但是在实践中发现,事实并非一定如此,由于监管的困难及委托代理问题的存在,信息化有可能因为人为的因素而导致组织的层级结构得到加强。这就需要组织实施有效的IT治理,使组织变革朝有利于组织发展的方向进行。     

Managing Network Resource and Organizational Capabilities to Create Competitive Advantage for SMEs in a Volatile Environment

By considering embedded opportunities and threats in today's dynamic business environment, this study proposes that small‐ and medium‐sized enterprises (SMEs) can exploit the ties of interfirm networks to access external resources and information, thus enhancing their organizational agility and absorptive capacity in a variable business environment and enabling superior organizational performance. This study enables SMEs to combine the external resources embedded in strategic networks with internal organizational capabilities including organizational agility and absorptive capacity to create an idiosyncratic competitive advantage in a chaotic business environment.     

Entrepreneurship in the Region: Breeding Ground for Nascent Entrepreneurs?

This paper employs data from the German Socioeconomic Panel (SOEP) and data from the German Social Insurance Statistics to study nascent entrepreneurship. In particular, micro data from the SOEP characterizing employees and nascent entrepreneurs is combined with data characterizing the entrepreneurial environment. The principal findings suggest that individuals are embedded in their local entrepreneurial environment which influences an individual especially at the beginning of the decision process about whether to become self-employed. Work and previous self-employment experience is more important than formal education for the likelihood of being a nascent entrepreneur. Furthermore, social capital is an important stimulus for nascent entrepreneurs. Finally, the results indicate that financial assets are less important for nascent entrepreneurs.

Doing by learning: Embedded application systems

We argue that the computerized information system should not look like a system on its own. Rather, it should be conceived as an inherent part of the work of its users. We therefore introduce the concept of an embedded system, which describes work tasks and organization. Computer‐supported information tasks are embedded in this environment: They are not parts of a system separated from other activities. This concept is based on the experiences gained during the development of a user‐interface prototype, derived from a theoretical frame of reference, called act orientation, to information systems, in which all computerized tasks are interpreted as acts performed by the actual user. Our suggestion continues the tradition of on‐line help and support, reaching radically deeper than usual in related approaches. We expect that our suggestion will, when applied, improve the control, productivity, quality of the outcome of work, and quality of working life, assessed from the user's point of view.     

The interplay between home and host institutions on CBA ownership decision

Cross-border acquisitions (CBAs) are one of the key strategies for internationalization. However, most of what is known about CBA strategies relies on the effects of the host country's environment or the home country's conditions. In this article, we analyze the interplay between these two important factors. We show that companies from less institutionally developed countries are more influenced by poor institutional conditions found in host countries. We analyzed a dataset of 1,390 cross-border acquisitions performed by Latin American firms. The literature on the subject points out that less developed host environments lead to fewer shares of ownership acquired in CBAs. However, we confirmed that the quality of the home country's institutional environment positively moderates the effects of the host environment over ownership choice in the acquisition. This effect is due to companies from less developed environments being able to use their embedded capabilities to better navigate faulty institutional environments abroad.
