This paper contributes to studies on dynamic capabilities (DCs) by showing that a neglected environmental contingency – i.e. the occurrence of a jolt – shapes the DCs–performance relationship. We focus on high-tech entrepreneurial ventures because these are the firms that jolts affect most; in so doing, we also advance the understanding of DCs in the entrepreneurship field. We argue that, in the aftermath of an environmental jolt, the high-tech entrepreneurial ventures that use internationalization and new product development capabilities to modify their resource configuration and regain environmental fit enjoy better performance. Econometric estimates on a sample of 340 Italian high-tech entrepreneurial ventures confronting the consequences of the global economic crisis that began in 2008 confirm that separately using these two DCs has a positive performance effect. This effect is stronger for relatively smaller ventures. Interestingly, despite synergies should arise from the combined use of the two DCs, we do not detect any superadditive effects. 相似文献

We reviewed the Journal of Applied Behavior Analysis (JABA), Journal of Organizational Behavior Management (JOBM), and Behavior Analysis in Practice (BAP) from 1990 to 2016, to identify articles that evaluated organizational behavior management interventions in a human service setting. Of those articles, 75 articles met the inclusion criteria for the review, 44 from JABA (1990 to 2016), 22 from JOBM (1990 to 2016), and 7 from BAP (2008 to 2016). We categorized each selected article by setting, employee population, client population, assessment, dependent variable, independent variable, and outcome measures. Results from the review are discussed for all three journals. Recommendations are made to broaden the scope of population and dependent variable targets, include more assessments, and include outcome data when applicable. 相似文献

Focusing on migrant social networks, this paper draws upon the sociology of time to incorporate complex notions of temporality into the research process. In so doing, we consider firstly, the challenge of going ‘beyond the snapshot’ in data collection to capture dynamism through time. Secondly, we apply the concepts of timescapes to explore ways of addressing the wider context and the interplay between spatiality, temporality and relationality in migration research. We argue that integrating a mixed methods approach to SNA, crucially including visualisation, can provide a useful methodological and analytical framework to understand dynamics.SNA can also be helpful in bridging the personal and structural dimensions in migration research, by providing a meso level of analysis. However, it is also important to connect the investigation of local and transnational networks with an analysis of the broader social, economic and political contexts in which these take shape; in other words, connecting the micro and the meso with the wider macro level. Drawing upon reflections from our migration research studies, we argue that different combinations of quantitative, qualitative and visual methods do not just provide richer sets of data and insights, but can allow us to better connect conceptualisations – and ontologies – of social networks with specific methodological frameworks. 相似文献

Testing an Integrative Contextual Career Development Model With Adolescents From High‐Poverty Urban Areas 下载免费PDF全文
Julia L. Conkel‐Ziebell Sherri L. Turner George V. Gushue 《The Career development quarterly》2018,66(3):220-232
Variations in the economic recovery rate across the United States have led to even greater chasms that separate the employed, unemployed, and underemployed (DeSilver, 2017 ). Therefore, understanding and supporting the career development of future generations is critical—especially for those who live outside the context of social privilege. The authors examined the applicability of the integrative contextual model of career development (ICM; Lapan, 2004 ) to a sample of 220 adolescents (129 boys, 91 girls) from a high‐poverty urban area. Results indicated that a canonical variate comprising foundational ICM skills (e.g., career exploration, goal setting) predicted a variate composed of ICM outcomes (e.g., self‐efficacy, vocational identity), thus supporting the usefulness of the ICM framework for this population. The skill of setting viable career goals was an especially strong predictor of outcomes. Implications for career counseling with adolescents living in high‐poverty urban areas and directions for future research are discussed. 相似文献

Supporting healthy lifestyle behaviours is a key aspect of preventing type 2 diabetes which disproportionately affects disadvantaged groups from a younger age. Formative participatory research was undertaken to design a program for young Aboriginal people in a remote town in North West Australia with a high level of health needs and relatively few prevention initiatives. Focus groups and advisory discussions with Aboriginal community members were used to determine the nature of the program. The need for a comprehensive program was consistently expressed and limited healthy lifestyle knowledge and difficulties with healthy eating influenced by food environments were noted to be important. With guidance from the Derby Aboriginal Health Service, findings were integrated with previous international research evidence to develop a program tailored to local Aboriginal people aged 15–25 years and refine it after piloting. This 8-session program, ‘Maboo wirriya, be healthy’ involved an education component consistent with the US Diabetes Prevention Program and practical activities including group exercise. Changes to program structure and documentation were made after piloting for future use. The community-directed approach used in this study is vital to ensure relevance of localised chronic disease prevention programs in a range of settings. 相似文献

ABSTRACTThe use of pop culture sources in social work education enhances the learning of MSW students in the human behavior, policy and diversity courses. Pop culture sources can enhance learning because of the potential for a quicker recall of content, revealing hidden talents and sophisticated understanding of the concepts, and making the assignments more enjoyable for students. However, the impact of utilizing pop culture sources among MSW students in research courses remains unknown. It is imperative that contemporary teaching modalities be implemented in research courses because MSW students have mixed feelings about taking research classes and conducting research of their own. The purpose of this article is to report findings of the implementation of a pop culture source-analyzing song lyrics-in an introductory MSW research class at one university in the USA. Qualitative and quantitative data were collected from (N = 17) MSW students. Findings lend support to utilizing the song lyrics exercise, as students reported enhanced self-efficacy and knowledge of the research process. Future research should assess the impact of this activity with larger samples. 相似文献

This study aims to systematically analyze and compare studies applying the dialogue approach in public relations to information communication technologies (ICTs) under English and Chinese context. Specifically, we want to investigate the subjects, the adoption of dialogic principles, and the processing of additional valuables of dialogue in selected studies. By identifying 68 relevant peer-reviewed journal articles under English context and 13 under Chinese context, we analyzed different subjects in selected publications, including their research topics, methods, samples and objectives. Moreover, our study also revealed the following results: (1) three dialogic principles were well adopted while the other two were not; (2) public engagement was the most common effect; (3) organizational response was the most common antecedent to dialogue implementation. Future studies are recommended to diversify research methods, topics and relevant technologies. We also call for developing theoretical models for dialogue in public relations and updating dialogic principles and measurements. Based upon the fact that the dialogue approach is less studied under Chinese context, we also offer a path to construct effective and ethical communication between organizations and publics on various ICT-based platforms in Greater China. 相似文献
