Wu, Xinyuan Zhang, R. Faff","doi":"10.7595/MANAGEMENT.FON.2018.0012","DOIUrl":"https://doi.org/10.7595/MANAGEMENT.FON.2018.0012","url":null,"abstract":"Research Question: Can we create a highly structured (but practical) abstract, which communicates the essential elements demanded by an expert scholarly reader? Motivation: A key aim of this journal is to enable “relevant information exchange and communication”. Information overload mean that readers are easily lost. Right at the start, poorly designed abstracts can fail to “hook” readers. Lost readers: is bad for authors, editors and for the journal. What’s new? While structured abstracts are not new, the “synergistic” combination of elements, combined with succinct guidance on content, is where the novelty lies. So what? Engaging readers in this way should lead to more journal activity – more reads, cites, submissions – and, ultimately, to an enhanced profile/reputation in the scholarly community. Idea: Building on Faff (2015, 2017) and Faff et al. (2017e) [“reverse engineering” and “pitch sparring”], we adapt the “Pitching Research” [PR] framework to create a structured and engaging abstract. Data: The “experimental” setting involves a sample of six high-performing non-research students, who signed up to an intense 4-week “research scholar” program over Winter 2017, at University of Queensland. Tools: The “Winter Scholars” are first taken through an “immersion treatment” on the PR framework. During this process, the students form three teams and each team is assigned an article to “spar” a reverse-engineered pitch summary-abstract. There are several iterative rounds of abstract design. Findings: The original pitch is limited to 1,000 words, an initial condensed abstract aims for 400 words and the final version is modified to 350 words. Three examples of the final structured abstract are created in Accounting, Finance and Management, providing “soft” “proof of concept”. Contribution: By creating a simple, focused and structured new abstract design adopted by this journal, we enhance the ability of the journal to meet its primary aim of enhancing “relevant information exchange and communication”. Over time, with growing use and application in this journal the reach of this contribution grows too. More generally, we argue that this novel abstract design increases awareness of the broader PR framework, helping readers and especially novice researchers better understand, describe and ultimately design their own scholarly research.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120995811","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}

The aim is thus to gain from internal and external perception the list of unique attributes that distinguish Serbia from other countries in the region. Qualitative research combined with semantic and sentiment analysis revealed existence of certain similarities and differences in both perceptions. People and unique Serbian mentality were recognized as the greatest differential advantage of Serbia, but also some negative attributes appeared like war legacy in external perception and internal problems in internal perception. Empirical evidence proved the presence of matching differential advantages in both perceptions and pointed to necessity of applying strategic approach in managing perception of Serbia.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128824210","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}

The subject of this study is the analysis of the existing stage, as well as of the achieved results in the implementation of the Big Data Technology in Serbia. Motivation: The success in managing the company depends on the ability to provide quality and comprehensive information by establishing personalized (1:1) communication with consumers on the global market in real or near real-time. This form of communication has become an imperative of the modern business decision-making process. Advanced Internet technologies, Cloud Computing (Cloud Technology), Big Data and Artificial Intelligence open a significant business potential for companies in Serbia to emerge on global markets. Idea: of this study is to perceive current business environment in Serbia through the prism of research development based on the Big Data technologies. Relevant hypotheses and conducted research have been set up with the aim of pointing to the potential of applying modern information-communication technologies, with an emphasis on artificial intelligence and the Big Data concept. Data: The survey was conducted on 154 business entities from the Serbian Business Register Agency’s database. The applied sampling method was a random analysis (selection was made randomly from the total number of selected companies, with the same probability of choice). Tools: An online survey was used, and respondents were contacted via e-mail. Findings: Research results, opinions and attitudes of managers, experts in the fields of marketing research and information technology, indicate a significant degree of justifiability of investments in new technologies in the Republic of Serbia and result in several proposals of certain measures and recommendations of incentives that should be conducted by the State. Contribution: The solutions in this paper are based upon the implementation of standardized procedures and advanced tools that could be used to overcome a \"bottleneck\" in the existing IT infrastructure, in order to enable a rapid collection and implementation of enabled data.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116127809","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":"Measuring the Potential for Technology Entrepreneurship Development: Serbian Case","authors":"Jovana Rakićević, Maja I. Levi Jakšić, M. Jovanović","doi":"10.7595/MANAGEMENT.FON.2018.0009","DOIUrl":"https://doi.org/10.7595/MANAGEMENT.FON.2018.0009","url":null,"abstract":"Research Question: This paper explores the potential for technology entrepreneurship development at the country level through the creation of a new composite index. Motivation: Motivation for this paper arises from the fact there is a lack of the composite indices used exclusively for technology management as identified by Jovanovic et al. (2017). Technology indices are mostly used as important components of other composite indices used for tracking a country performance from the perspective of other global phenomena (e.g. competitiveness and innovativeness). The novelty of this paper reflects in the proposed Technology Entrepreneurship Development Potential (TED-pot) index which has multiple significances. It could serve as a help for policy makers in creating national policies; other companies and countries looking for the adequate environment to invest in technology entrepreneurship projects; academics who benefit from a new country-level view on technology entrepreneurship, especially ICT entrepreneurship. Idea: The idea of the paper was to create the TED-pot index to enable the cross-countries comparisons and examine whether the potential of Serbia lies in its entrepreneurial ICT sector. Data: Four indicators included in the created index are measured by the World Bank. The index is applied on six ex-Yugoslav countries and the EU for the period 2009-2014. All the data is collected from the World Bank database. Tools: The final index value is obtained by using the simple weighted function with equal weights. The overall TED-pot has been built upon the equal weighting of the two created pillars: ICT potential (ICT-pot) and Entrepreneurial potential (E-pot). The values for each pillar are calculated by the same procedure, through the simple mean of certain indicators. Findings: According to the calculated TED-pot values, Serbia stands out as a country with the greatest potential for technology entrepreneurship development in the region. Analysing individual pillars, ICT-pot indicates Serbia has very strong ICT sector, far ahead of other countries in the region, while the E-pot values show there is a space for administration to ease and speed up the process of starting new businesses in Serbia. This is a pilot research and the first presentation of the created index, which calls for further investigation. Contribution: This paper expands exiting research related to the country-level measurement in the field of technology management and entrepreneurship, especially focusing on ICT entrepreneurship development.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122957128","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}

Lepojević","doi":"10.7595/management.fon.2021.0022","DOIUrl":"https://doi.org/10.7595/management.fon.2021.0022","url":null,"abstract":"Research Question: The paper examines the impact of specific Hofstede’s dimensions of national culture on entrepreneurial culture, depending on the wealth of the national economy. Motivation: Based on the results of some previous research focused on the relationship between national culture and various indicators associated with entrepreneurship (Hayton, George & Zahra, 2002; Pinillos & Reyes, 2011; Zhao, Li & Rauch, 2012; Hayton & Cacciotti, 2013), the paper analyses the impact of national culture on entrepreneurial culture, as a category closely related to entrepreneurship. The identification of the national culture's dimensions contributing to the affirmation of entrepreneurial culture, provides an insight into the entrepreneurial potential of a particular national economy. Idea: The main idea of the paper is to examine whether selected Hofstede’s dimensions of national culture (power distance - PD, uncertainty avoidance – UA, individualism – IDV) affect entrepreneurial culture (EC) in a manner identical to that affecting the other indicators of entrepreneurship. The mentioned relationship is not examined as unmediated, but in the context of the effect that national wealth (measured as Gross National Income per capita - GNI) has on it. Data: The survey covered a total of 108 countries for which the data on the values of three selected dimensions of national culture, the index of entrepreneurial culture and the Gross National Income per capita are available. Tools: In order to examine the effect of three selected Hofstede’s dimensions of national culture on entrepreneurial culture, correlation and standard multiple regression analyses were conducted. For data processing, statistical software SPSS (version 22.0) was used. Findings: The obtained results of the research show that in national economies with higher levels of IDV and lower levels of UA, higher scores of the EC index are manifested, regardless of the national wealth. On the other hand, the impact of PD on EC is determined by the level of a particular economy's wealth. In high-income economies (HIE), the index of EC is higher if PD is lower. In low- and middle-income economies (LIE), higher values of EC index are manifested if PD is higher. Contribution: The paper expands the knowledge and research base on entrepreneurial culture and the influence that national culture has on it.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117254555","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}

Motivation: Our goal was to determine whether real estate has been overpriced, i.e., whether and when speculative bubbles began to form and whether there were indications of their bursting. This paper brings together the need for discussing theories that can potentially explain the real estate market bubbles and boom-bust cycles (Gleaser &Nathanson, 2014) and the new approach which proved promising to detect the exuberance of economic and financial activities (Phillips, Shi &Yu, 2015). Potential collapse of real estate prices would have devastating effects and would likely cause a collapse of the financial system. Idea: The core idea of this paper was to evaluate whether speculative bubbles could be detected in the real estate market over the period immediately before the outbreak of the COVID-19 virus pandemic, and whether the pandemic or the financial crisis arising from it led to bursting of bubbles in this market and consequently brought their economies into even deeper crises. Data: Quarterly price movements were analyzed in the real estate market in six countries: Italy, Spain, the United Kingdom, Serbia, Croatia and Slovenia in the period Q1 1980 - Q4 2019 for Italy, Spain and the United Kingdom; Q1 2002 - Q4 2019 for Serbia and Croatia and Q1 2007 - Q4 2019 for Slovenia. Tools: Empirical analysis has been performed by utilizing generalized sub-augmented Dickey-Fuller (GSADF) test of unit roots for the detection and data stamping of bubbles in the real estate market in time series at hand. Findings: In conclusion, grand European shutdown and COVID pandemic apparently did not prick multiplicity of previously formed real estate bubbles, at least not for the time being. Moreover, in several developing countries with stunted financial markets, the virus may have somewhat paradoxically solidified real estate prices and even sustained a build-up of rational real estate bubbles. Contribution: This paper expands previous research on real estate bubbles and provides new insights into the initial consequences of the COVID-19 pandemic.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122910932","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}

Motivation: The main motivation for this research study was: to examine a compromising conflict resolution in the public sector in Serbia; to examine the frequency, causes, conflict resolution strategies and methods for their reduction and for improving work climate in the public sector in Serbia; to examine the job satisfaction in the public sector in Serbia; and to examine the relationship between workplace conflicts and job satisfaction in the public sector in Serbia. Idea: This research started with the intention to study job satisfaction or dissatisfaction and workplace conflicts in the public sector in Serbia in order to reach a more efficient and effective human resource management. Data: The research study was conducted from the beginning of March 2019 until the end of April 2019. The total sample size amounted to 300 respondents employed in the public sector in Serbia. Tools: Two scales have been used to gather data and conduct the research: the compromising conflict resolution scale and the job satisfaction survey scale. Findings: More than half of the respondents employed in the public sector in Serbia believe that conflicts in their workplace are not frequent, while less than half of them finds them frequent. This finding shows that opinions are divided regarding conflicts. As the main reason for conflicts, the respondents reported personal conflicts, organizational conflicts and communication conflicts. The best strategies to handle conflicts, according to the employees in the public sector in Serbia, are cooperation, competition and avoiding. At the same time, compromise occupies the bottom place according to its frequency occurrence. As regards the methods to lower the levels of conflict frequency and to improve the organizational climate, the employees in the public sector in Serbia emphasized better planning and division of work and more resources that a company has at its disposal. Regarding job satisfaction, these findings put employees in the category of ambivalent emotions.

Motivation: The survival, growth and development of companies in the current business environment are conditioned by their capability to reach socially responsible decisions and carry out activities that meet the expectations of different stakeholders. The main motive for this research has stemmed from the current global corona virus pandemic and the way this state of affairs has affected socially responsible behaviour of companies. The research of activities Serbian companies carried out in the time of crisis prompted us to explore the possible relationship between corporate social responsibility and its effects on corporate reputation, and consequently business results. Research idea: An empirical research has been conducted with the view to investigate the position of the public on the importance and impact of CSR on corporate reputation, and also to determine the key factors that guide the decisions of people living in the Republic of Serbia to shop, bearing in mind the socially responsible behaviour of companies. Data: The sample included 173 respondents, the number that allowed valid conclusions. The questionnaire was anonymous; all the respondents were residents of Serbia with access to the internet and willing to fill in the questionnaire, either by following the link advertised on social media or replying to the e-mail. Tools: The gathered data were processed and analysed using descriptive and explorative statistics. Research hypotheses were tested by: Frequency tables, Crosstable procedures, Paired Samples t-test, Spearman`s coefficient of correlation, Chi-square test, and Phi coefficient of correlation, resulting in conclusions and corresponding suggestions. Findings: Respondents perceive companies as social actors driven not only by profit, but by the interest of the community and their business environment. They believe companies can assume their responsibilities through different aspects of doing business, especially by contributing to the improvement of their consumer’s lifestyle. The majority of respondents tend to buy from companies they perceive as socially responsible from the point of view of further development of the society and their ethical behaviour towards the community.  Contribution: The findings can encourage the company’s management to direct their financial and organizational resources into the better management of the CSR, especially during the crisis, because solidarity and care for the most vulnerable part of the population lead to an improvement in the reputation and business results of a company.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121667488","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}

Motivation: Consumer lifestyle is largely shaped by the effects of the culture to which consumers belong. Starting from the relevant Kotler & Keller (2017) consumer behaviour model that demonstrates the previously given fact, as well as identified research gap related to investigating the influence of Hofstede's national culture dimensions on activities, interests and opinions as lifestyle components, the study gives useful insights into the importance of knowing and respecting cultural differences when defining marketing strategies that aim to shape or influence a particular consumer lifestyle. The study contributes to the existing literature by providing a new idea for developing a research framework that could be used in cross-cultural or consumer behaviour studies. Idea: The basic idea of this study is to empirically test the relationship between national culture dimensions and consumer lifestyle components. The study was conducted using collectivism and femininity as independent variables, and activities, interest and opinions, i.e., lifestyle components as dependent variables. Data: Empirical research was conducted on a sample of 251 consumers from central Serbia using a survey method during July and August 2020. Tools: Processing of primary data was performed using statistical software SPSS 20 and AMOS 20 utilizing descriptive statistics, reliability analysis, correlation analysis, confirmatory factor analysis and structural equation modelling. Findings: The study first confirms the presence of collectivism and femininity as Serbian national culture dimensions, and then indicates the existence of a statistically significant effect of observed national culture dimensions on consumer lifestyle components. Related to this, results indicate the existence of a statistically significant effect of femininity on activities and opinions, while collectivism determines only activities as a lifestyle component.

Ivić","doi":"10.7595/management.fon.2021.0029","DOIUrl":"https://doi.org/10.7595/management.fon.2021.0029","url":null,"abstract":"Research Question: This paper aims at adjusting the logistic regression algorithm to mitigate unwanted discrimination shown towards race, gender, etc. Motivation: Decades of research in the field of algorithm design have been dedicated to making a better prediction model. Many algorithms are designed and improved, which made them better than the judgments of people and even experts. However, in recent years it has been discovered that predictive models can make unwanted discrimination. Such unwanted discrimination in the predictive model can lead to legal consequences. In order to mitigate the problem of unwanted discrimination, we propose equal opportunity between privileged and discriminated groups in the logistic regression algorithm. Idea: Our idea is to add a regularization term in the goal function of the logistic regression. Therefore, our predictive model will solve both the social problem and the predictive problem. More specifically, our model will provide fair and accurate predictions. Data: The data used in this research present U.S. census data describing individuals using personal characteristics with a goal to provide a binary classification model for predicting if an individual has an annual salary above $50k. The dataset used is known for disparate impact regarding female individuals. In addition, we used the COMPAS dataset aimed at predicting recidivism. COMPAS is biased toward African-Americans. Tools: We developed a novel regularization technique for equal opportunity in the logistic regression algorithm. The proposed regularization is compared against classical logistic regression and fairness constraint logistic regression, using a ten-fold cross-validation. Findings: The results suggest that equal opportunity logistic regression manages to create a fair prediction model. More specifically, our model improved both disparate impact and equal opportunity compared to classical logistic regression, with a minor loss in prediction accuracy. Compared to the disparate impact constrained logistic regression, our approach has higher prediction accuracy and equal opportunity, while having a lower disparate impact. By inspecting the coefficients of our approach and classical logistic regression, one can see that proxy attribute coefficients are reduced to very low values. Contribution: The main contribution of this paper is in the methodological part. More specifically, we implemented an equal opportunity in the logistic regression algorithm.","PeriodicalId":429254,"journal":{"name":"Management:Journal of Sustainable Business and Management Solutions in Emerging Economies","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117213418","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}
