A systematic literature review on entrepreneurial intentions: citation, thematic analyses, and research agenda

Abstract: Entrepreneurial intention is a rapidly evolving field of research. A growing number of studies use entrepreneurial intention as a powerful theoretical framework. However, a substantial part of this research lacks systematization and categorization, and there seems to be a tendency to start anew with every study. Therefore, there is a need to take stock of current knowledge in this field. In this sense, this paper carries out a review of the literature on entrepreneurial intentions. A total of 409 papers addressing entrepreneurial intention, published between 2004 and 2013 (inclusive), have been analyzed. The purpose and contribution of this paper is to offer a clearer picture of the sub-fields in entrepreneurial intention research, by concentrating on two aspects. Firstly, it reviews recent research by means of a citation analysis to categorize the main areas of specialization currently attracting the attention of the academic community. Secondly, a thematic analysis is carried out to identify the specific themes being researched within each category. Despite the large number of publications and their diversity, the present study identifies five main research areas, plus an additional sixth category for a number of new research papers that cannot be easily classified into the five areas. Within those categories, up to twenty-five different themes are recognized. A number of research gaps are singled out within each of these areas of specialization, in order to induce new ways and perspectives in the entrepreneurial intention field of research that may be fruitful in filling these gaps.

Effective negative-/spl epsiv/ stopband microstrip lines based on complementary split ring resonators

Abstract: In this letter a super-compact stopband microstrip structure is proposed. The frequency gap is produced by an array of complementary split ring resonators (CSRRs)-a concept proposed here for the first time-etched on the ground plane. This behavior is interpreted as due to the presence of a negative effective dielectric permittivity in the vicinity of resonance. The resulting device produces a deep rejection frequency band with sharp cutoff, and a pass band that exhibits very low losses and good matching. Due to the sub-lambda operation of CSRRs, the electrical size of the device is very small.

Polychoric versus Pearson correlations in exploratory and confirmatory factor analysis of ordinal variables

Abstract: Given that the use of Likert scales is increasingly common in the field of social research it is necessary to determine which methodology is the most suitable for analysing the data obtained; although, given the categorization of these scales, the results should be treated as ordinal data it is often the case that they are analysed using techniques designed for cardinal measures. One of the most widely used techniques for studying the construct validity of data is factor analysis, whether exploratory or confirmatory, and this method uses correlation matrices (generally Pearson) to obtain factor solutions. In this context, and by means of simulation studies, we aim to illustrate the advantages of using polychoric rather than Pearson correlations, taking into account that the latter require quantitative variables measured in intervals, and that the relationship between these variables has to be monotonic. The results show that the solutions obtained using polychoric correlations provide a more accurate reproduction of the measurement model used to generate the data.

Factors affecting entrepreneurial intention levels: a role for education

Abstract: A considerable agreement exists about the importance of promoting entrepreneurship to stimulate economic development and employment generation In particular, entrepreneurship education has been considered one of the key instruments to increase the entrepreneurial attitudes of both potential and nascent entrepreneurs Nevertheless, the factors that determine the individual’s decision to start a venture are still not completely clear Cognitive approaches have attracted considerable interest recently But the explaining capacity of personality traits or demographic characteristics is still considered Therefore, there is a need to clarify which elements play the most influential role in shaping the personal decision to start a firm This paper tries to contribute to filling this gap by providing empirically-based suggestions for the design of improved entrepreneurship education initiatives The empirical analysis is based on two essential elements: firstly, an already validated instrument (EIQ); secondly, a statistical method (factor-regression procedure) which is not dependent on any theoretical approach It uses all the information collected through the questionnaire items, selecting them solely based on their capacity to explain the dependent variable Results will allow the design of more effective education initiatives They suggest that personal attitude and perceived behavioural control are the most relevant factors explaining entrepreneurial intentions Thus, based on these results, a number of considerations about the most effective role of education in promoting and developing attitudes and intentions towards entrepreneurship are considered Besides, the EIQ could be used as an evaluation instrument for entrepreneurial education programmes
