Evaluating and tracking qualitative content coder performance using item response theory

Content analysis of traditional and social media has a central role in investigating features of media content, measuring media exposure, and calculation of media effects. The reliability of content coding is usually evaluated using “kappa-centric” agreement measures, but these measures produce results that aggregate individual coder decisions which obscure the performance of individual coders. Using a data set of 105 advertisements for sports and energy drinks media content coded by five coders, we demonstrate that Item Response Theory can track coder performance over time and give coder-specific information on the consistency of decisions over qualitatively coded objects. We conclude that IRT should be added to content analysts’ tool kit of useful methodologies to track and evaluate content coders’ performance.

Entrepreneurial intention among University students in Malaysia: integrating self-determination theory and the theory of planned behavior

The present study endeavors to develop a deeper understanding of the motivational processes involved in intentional entrepreneurial behavior. For this purpose, it integrates the social cognitive approach of the theory of planned behavior (TPB) and the organismic theory of motivation of self-determination theory (SDT). More specifically, it tests the role of basic psychological needs of autonomy, competence and relatedness as defined in SDT in shaping university students’ attitudes and intentions toward entrepreneurship. The sample of this study consisted of 438 (Males?=?166, Females =272) 3rd and 4th year university students from four Malaysian Public Universities. The results of the study show that the model strongly explains about 71% of the variance in entrepreneurial intention. Basic psychological needs of autonomy, competence and relatedness have a strong indirect impact on entrepreneurial intention via their attitudinal antecedents: attitude, subjective norm, and perceived behavioral control. This indicates a full-mediational model, where the attitudinal factors operated as transmitters of effects from the distal constructs of SDT on entrepreneurial intention. These findings confirm that both SDT and the TPB provide complementary explanations of the motivational processes of entrepreneurial behavior. The study contributes to the existing knowledge by providing a theory-based understanding of the role of motivations in the formation of entrepreneurial intentions. It opens the way for future research to analyze how alternative motivations may affect new venture creation, survival and success.

A metamodel approach towards self-determination theory: a study of New Zealand managers' organisational citizenship behaviours

The present study brings together the multiple dimensions of self-determination theory (SDT), the three facilitators (global aspirations, global motivation and mindfulness), the three needs (autonomy, competence and relatedness) and perceived autonomous support (PAS) towards the organisational citizenship behaviours (OCBs) of 386 New Zealand managers. SDT suggests that individuals with higher SDT dimensions will achieve greater motivation and well-being; however, few studies include more than one SDT dimension. The findings show that overall the majority of SDT dimensions were significantly correlated to OCB dimensions. Moderated regression analysis found that autonomous motivation was positively related to OCBs with controlled motivations negatively related to OCBs. PAS and most of the need satisfaction dimensions were also positively related to OCBs. Intrinsic aspirations were only related to OCBs individual. PAS was also tested as a moderator of SDT dimensions, and five significant interactions were found to influence OCBs individual and one to influence OCBs organisational. Overall, the highest levels of OCBs were reported by managers with higher than average PAS and those who rated highly on the SDT dimensions. This study provides strong and consistent support that SDT dimensions influence OCBs, and the consistent influence of PAS highlights the importance of workplace context.

Perception of organization's value support and perceived employability: insights from self-determination theory

Perceived employability (PE; i.e. the worker's perception about available job opportunities) is portrayed as the upcoming resource for workers and organizations. However, organizations might particularly want to stimulate perceptions of job opportunities on the internal labor market (i.e. internal PE). In contrast, they may be hesitant in stimulating perceptions of job opportunities on the external labor market (i.e. external PE), as this might foster workers' voluntary turnover. The contextual influences adding to these different types of PE are relatively unknown. Building upon self-determination theory, we argue that the organization's support of intrinsic (e.g. personal growth) and extrinsic (e.g. status) values may play a critical role. In line with expectations, the results reveal a positive association of the perceived organization's support of intrinsic work values and a negative association of the perceived extrinsic value support with internal PE, both in terms of a similar job (i.e. internal lateral PE) and a better job (i.e. internal upward PE). Unexpectedly, perceived organization's support of extrinsic values did not relate negatively to external PE. These results show that employers can invest in the workers' employability without disadvantaging the organization. To arrive at a flexible workforce, the support of intrinsic values is of key importance.     

Revisiting agency and transaction costs theory predictions on vertical financial ownership and contracting: electronic integration as an organizational form choice

This paper provides an organizational economics foundation to guide managers in matching the comparatively more efficient organizational mode with transactional characteristics such as: (1) the degree of (human capital) asset specificity involved in the transaction, (2) the degree of uncertainty surrounding the transaction, and (3) the number of trading partners (suppliers and buyers) in the vertical supply chain. The key role of technology, and more specifically the e‐business infrastructure and its effects on organizational mode choice, is highlighted. The main results from this analysis suggest that changes in information technology are changing the nature of transaction costs leading to more efficient management through an electronic integration solution thus favoring contracting and outsourcing than would have been technologically possible when Williamson's Markets and Hierarchies (Markets and Hierarchies: Analysis and Antitrust Implications. Free Press: New York, 1975) was published. It is emphasized that the transaction cost economics principles are durable but that the breathless advances in information technology, especially in the past decade, have comparatively favored lower transaction costs of markets over hierarchies.

Understanding undergraduate students’ experience: a content analysis using NSSE open-ended comments as an example

This study demonstrates how a qualitative content analysis method may be used to help understand undergraduate students’ experience. We examine and rationalize the methodological concerns regarding content analysis of open-ended comments in the qualitative study. We describe a data analysis technique, using qualitative responses from National Survey of Student Engagement (NSSE) as an example, and highlight the findings in a thematic way to convey how undergraduate students perceive issues that challenge them to develop skills, awareness, and confidence, as well as the potential factors that influence student engagement and future success. Finally, we provide potentials of how these findings can be utilized to improve student experience, limitations of this study as well as suggestions for future research.

This paper extends a fundamental temporal diffusion model to integrate space and time dimensions of the diffusion of innovation. The analogous developments in physical sciences are compared and it is demonstrated that the proposed model may be the first step in linking the concept of catalysts in physical science diffusion processes to the role of change agents in social science systems.     

Effects of sport mega-events on city brand awareness and image: using the 2009 world games in Kaohsiung as an example

The purpose of this study was to explore the influence of holding sport mega-events on city brand awareness and city brand image, using the 2009 World Games in Kaohsiung and the people of Taiwan as the research subjects. Convenience sampling was used for distribution of the questionnaire, and 1,272 valid samples were obtained. SPSS 12.0 statistical software was used for structural analysis of the samples, and LISREL 8.20 statistical software was used to conduct confirmatory factor analysis on the various dimensions of the questionnaire. Finally, the structural equation model (SEM) was used to analyze the model and confirm that it had a good fit. This study made a number of important findings. The hosting of sport mega-events has a significant effect on city brand awareness. City brand awareness has a significant effect on city brand image. Sport mega-events have an indirect effect on city brand image, and city brand awareness has a mediating effect. These research results could be used as a reference for cities that actively seek to establish city branding.
