The core objectives of the research study are to determine the level of effectiveness and relationship between E-Recruitment and the HR department of private HEI’s of Karachi. A worklist can be found on industrial sectors, service sectors in the context of e-recruitment, but the research gap on educational institutions particularly Private HEI’s is still there. An in-depth literature review is discussed. The research methodology briefs that, this study was both an Explanatory and Exploratory design in nature. 2 self-developed questionnaires were utilized. Using SPSS version 25.0, the researchers performed several tests including descriptive statistics, reliability test, KMO, Bartlett’s test, Pearson Correlation, and Multiple Regression tests. The results have proved that there is a strong positive relationship between independent and dependent variables and the relationship between them is accepted at a 5% significance level. Also, it was evidenced from interviews that E-recruitment is a cost-beneficial method, has a greater geographical reach, shortened recruitment procedures, provides reliability in the recruitment procedure, and also facilitates the selection process of the HR department.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79230135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the research question asks how urban policies in Poland support knowledge spillovers and entrepreneurship in comparison to German cities’ policies. Also investigated is how do Polish and German cities support entrepreneurship in different forms (including social entrepreneurship, youth entrepreneurship, and creative industries). Methodology: To answer this question, we have adopted a multiple-case study methodology relying on multiple sources of evidence, primarily strategic documents of the biggest Polish cities in the context of cross-country comparison with selected large cities in Germany, and semi-structured interviews with decision-makers representing municipalities from the analyzed cities in Poland. Building on the concept of the knowledge spillover theory of entrepreneurship, we refer to the approach in which spillovers of knowledge are a strategic lever through which firms distribute innovation and have profound implications for the region’s entrepreneurial activities development. Findings/research and practical implications: The research enriches our understanding of urban policies in Poland that support knowledge spillovers and entrepreneurship, and discovers the possible relationship between factors determining entrepreneurship in Polish and German cities. In all Polish and German cities, entrepreneurship was an important component of economic development strategy. However, Polish cities depend on EU funding to a much greater extent than German cities in implementing their economic development strategies. Cluster strategies in the framework of key cities’ industries were embedded in most urban policies, but a majority of Polish respondents believed that their cities should place greater emphasis on this policy. The main challenge for policy-makers is that current entrepreneurial polices should be more effective and oriented towards reinforcing the social perception of entrepreneurship, especially among young inhabitants. Originality/value: The research allowed enough data to be gathered to answer the research questions. However, future research validating the results in quantitative study is suggested.

Specifically, this study explores the moderating effects of entrepreneurial self-efficacy on the relationships between attitude towards entrepreneurship, subjective norms, perceived behavioral control, and intention to become entrepreneurs. Methodology: By adapting the theory of planned behavior and using data collected from 2218 students in Vietnam, the author utilizes a meta-analytic path analysis in order to show that entrepreneurial intention is strongly influenced by attitude towards entrepreneurship, followed by self-efficacy and perceived behavioral control. Particularly, structural equation modeling (SEM) was employed to test the model fit and hypothesis. Findings: The study indicates that subjective norms have both direct and indirect effects on entrepreneurship intention. Moreover, although the moderating impacts of self-efficacy on the relationships between subjective norms and perceived behavioral control is insignificant, the research study indicates that self-efficacy moderates the correlation between attitude towards entrepreneurship and start-up intention. Implications for theory and practice: Besides its contributions to entrepreneurship literature, this study also contributes to practices and implications at universities in Vietnam. Originality and value: These findings also illustrate that the theory of planned behavior can be appropriately implemented in the research context of emerging economies such as Vietnam. In addition, the study shows that the relationship between attitude towards entrepreneurship and entrepreneurial intention is moderated by entrepreneurial self-efficacy.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76235035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Dynamics of the evolution of the strategic management concept: From the planning school to the neostrategic approach","authors":"Tomasz Kafel, B. Ziębicki","doi":"10.7341/20211721","DOIUrl":"https://doi.org/10.7341/20211721","url":null,"abstract":"Purpose: Strategic management has been developing in business theory and practice for over 50 years. Presently, it constitutes the main area of research interest in management science. The contemporary conditions of business operations create new challenges for strategic management, such as the use of dynamic capabilities in strategy building, relational strategies, networking of organizations, technology development and automation of processes, and global strategies. These challenges are often referred to as neostrategic management. The purpose of this publication is to present the findings of research concerning new strategic management concepts and challenges. Methodology: The main research method of this article was a narrative literature review. On the basis of the research, the development of the concepts as well as contemporary trends and challenges of strategic management were characterized. There is also a synthesis of the problems and research results presented in the articles in this special issue of JEMI. Findings: Various schools and approaches to strategy formulation have been created. They indicate different factors that allow for success in strategic management such as: setting long-term goals, selection of programs and their execution plans (planning school); connection of the enterprise with the environment (evolutionary school); focusing attention on competitive advantage and achieved performance (position-based school); focus on one’s own resources and competences (resource school); use of opportunities and creating innovation (simple rules school); selection of the best option and orientation in business management (real options school); or eclectic perspectives, integrating the listed approaches. The strategic management concept has two dimensions. The first dimension is related to the emergence of subsequent, new strategic management concepts, which often hark back to the previous schools and approaches. The second dimension of development applies to operationalization and adjustment of the previous concepts to the changing conditions. Implications for theory and practice: The paper characterizes the research results presented in the articles included in this JEMI issue. They deal with various problems and challenges in the field of strategic management, such as the relationship between market dynamics, market orientation and performance of enterprises; the innovativeness of companies as a contemporary strategic orientation of companies; the strategy implementation and the management of the organization change; problems of strategic management of the development of the city. Originality and value: The problems presented in the study relate to challenges and new concepts in strategic management. They enrich the existing knowledge on the development of strategic management, and also create inspiration for further research in this area.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82777641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kravchenko","doi":"10.7341/20211745","DOIUrl":"https://doi.org/10.7341/20211745","url":null,"abstract":"PURPOSE: The purpose of this study was to conduct a comparative analysis of knowledge management (KM) initiatives in small, medium, and large enterprises operating in Ukraine, and to highlight the specific characteristics of KM policies, as well as the scope and intensity of KM tools application in these categories. In particular, the study focused on the consistency between the awareness of knowledge/KM importance and KM policies, and the scope and intensity of the application of both human-centered tools and information communication technology (ICT) tools. METHODOLOGY: The concept of the study was developed on the basis of an integrative socio-technical perspective. The empirical data were obtained through a questionnaire survey among 90 managers of small, medium, and large Ukrainian enterprises and were analyzed statistically. FINDINGS: Both common and distinctive characteristics of these categories in terms of KM were highlighted. Although all enterprises, regardless of their size, showed a high awareness of knowledge/KM importance for their business, significant distinctions between small and large enterprises were found with regard to their KM policies, the scope of advanced KM tools application, and the intensity of some traditional and advanced KM tools application. In all cases, large enterprises showed higher levels of these characteristics compared to small enterprises, whereas medium enterprises were more similar to large enterprises. In contrast to the common view on SMEs as a homogeneous sector in terms of KM, the study shows its heterogeneity in terms of KM initiatives. According to a number of indicators studied, significant differences were observed between small and large enterprises, whereas the distinctions between medium and large enterprises were much less obvious. IMPLICATIONS FOR THEORY AND PRACTICE: The theoretical contribution of this study was the provision of SMEs sector heterogeneity evidence based on a number of KМ characteristics. This finding allows us to deepen our knowledge of conceptual differences in KM approaches, applied by different enterprise categories. From a practical perspective, an enterprise size should be taken into account while designing specific KM policies, programs and tools to meet enterprises’ needs to a greater extent. The larger the enterprise is, the more structured, deliberate, and conscious the KM approach that should be applied is. ORIGINALITY AND VALUE: No empirical research that addresses the comparative analysis of KM initiatives in small, medium, and large enterprises operating in Ukraine, as well as in other transition economies of post-Soviet states, has been previously performed, and this study fills the gap.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84620765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Is dominant logic a value or a liability? On the explorative turn in the German power utility industry","authors":"E. Brandtner, Jörg Freiling","doi":"10.7341/202117225","DOIUrl":"https://doi.org/10.7341/202117225","url":null,"abstract":"Purpose: This study seeks to specify the role of ‘dominant logic’ in an organization. So doing, the ambiguous character of the dominant logic emerges, as on the one hand, a dominant logic can make sense of a change, provide useful guidelines and keep the company focused. However, on the other hand, a dominant logic may provide reasons why preventing change could be ‘logical’ or work as a blinder when it comes to interpreting up-and-coming developments. Therefore, a dominant logic can be a value and a liability in times of change. Methodology: This study sets out to contribute to prior research by raising two questions. First, how can we re-conceptualize the construct of dominant logic to address both the driving and the hampering role in the case of explorative turns? And, second, which factors restrain and which allow explorative turns? With special regard to the German energy transition in the 2010s, this research grounds on explorative qualitative empirical research and employs a single case-study design for a traditional German power utility company, which – as an incumbent – has to deal with the high complexity in the German power industry. Data sources are in-depth and problem-centered interviews with both internal and external experts as well as field observations. An inductive procedure allows the development of research propositions from data, framed by prior research. Findings: As a result, this study delivers a six-factor framework to shine a light on the micro-foundations of dominant logic. Whether a dominant logic is of value or is a liability in organizational change and allows an explorative turn, depends on the identified abilities to unlearn, to explore, to change and to manage. Data suggests that an explorative turn, driven by dominant logic, works better in the case of combined learning and unlearning capacities, an ambidextrous balance of exploration and exploitation, co-existing logics, continuous adaptations of dominant logic and lower levels of leadership power and formal structures. Implications for theory and practice: This study specifies the roles of dominant logic that may hamper explorative turns in times of severe disruptions. Originality and value: It contributes to the research of managerial cognition by refining and applying the concept of dominant logic. It provides empirical evidence on how this phenomenon creates inertia, drives change, and discusses the needs for and the barriers to an explorative turn. From a managerial viewpoint, dominant logic serves as a filter to identify required changes and to tune the speed of change. This, however, depends on managerial reflection on the appropriateness of dominant logic in the run of events.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76431168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: The two methods used for performing the quantitative empirical research are CAWI and PAPI. The research sample included MSMEs operating in technology parks in Poland. The article is the answer to the needs for systematic research of models between market orientation and firm performance. Findings: The research findings provide an insight into the level of market orientation and performance of the analyzed MSMEs operating in technology parks in Poland. It was found that MSMEs in the research sample were not a homogeneous group in this respect. It has been proven that market orientation is a significant stimulant of firm performance, while market dynamism has not been classified as a moderator of the market orientation–firm performance relationship. Implications for theory and practice: This study contributes to strategic management by identifying the key role of market orientation for enterprises wishing to benefit from this type of strategic orientation. The important role of the predictor – market orientation in shaping the results of micro, small and medium-sized enterprises operating at TPs in Poland has been proven. In practice, this means that increasing the level of market orientation is conducive to increasing positively assessed financial performance. Originality and value: Our research carried out at MSMEs operating in technology parks in Poland enriches and supplements knowledge about market orientation as a phenomenon of universal character because it also applies to smaller sized business organizations.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89837719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Networks and network strategies: New theorization based upon a systematic literature review","authors":"Rossella Canestrino, Amir Forouharfar","doi":"10.7341/20211732","DOIUrl":"https://doi.org/10.7341/20211732","url":null,"abstract":"PURPOSE: This paper aims to introduce a general all-embracing taxonomy of networks and its relevant strategies to facilitate the teaching and learning of the strategic concepts of networks in strategic management. METHODOLOGY: To fulfill its intention, the paper has adopted a systematic literature review (SLR), since the introduced taxonomy and its corresponding strategies should be a compendious reflection and summary of the current literature of the studies on strategic networks. RESULTS: The paper unfolded seven potential configurations of the networks and then proceeded with the proposition of their relevant strategies with regard to the networks’ relationships and forms. These networks were named as Reciprocally Interdependent Networks, Sequentially Interdependent Networks, Partnering Networks, Complementary (Overlapping) Networks, Supporting (Logistic) Networks, Distributing Networks, and Co-Innovation Knowledge-Sharing Networks. Their corresponding network strategies were identified as Multi-Level Promotion Strategy, Just-In-Time Strategy, Network Partnership Strategy, Compensatory Strategy, Network Logistic Strategy, Distributing Network Strategy, and Network R&D Strategy, respectively. IMPLICATIONS FOR THEORY AND PRACTICE: Systematics or a system of classification is a fundamental necessity in any field of knowledge, benefiting both academia and learners. Accordingly, this paper provides a comprehensive but concise means of classifying networks and their strategies to overcome the paucity still existing in the literature. These efforts invite future research and conversation about networks and network strategies, proposing a guiding framework for the debate. ORIGINALITY AND VALUE: Lack of consensus about theories and conceptualizations in strategic network studies became an inspiration for this research, which allowed for the clarification of the mentioned existing paucity.","PeriodicalId":44596,"journal":{"name":"Journal of Entrepreneurship Management and Innovation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73594001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
