Does ethnicity count when contextualizing the low proportion of women in STEM in Serbia?
Authors: Lendák-Kabók Karolina 
Published: December 2020

PurposeThe aim of this article is to explore the perceptions of women in science, technology, engineering and mathematics (STEM) fields in two ethnic groups (majority Serb and minority Hungarian) in a multiethnic region – Vojvodina, in Serbia – from an intersectional perspective.Design/methodology/approachA qualitative study was implemented, capitalizing on in-depth, semi-structured interviews with university faculty members from two ethnic groups working in a multiethnic region of Serbia (Vojvodina) in the STEM field of studies. Intersectionality as a theoretical approach was applied to reveal the interconnectedness between gender, ethnicity and field of studies.FindingsThe intersectional analysis indicates that minority Hungarian women are more conservative and less inclusive toward other women in STEM, thus they continue to build and enforce gender-based stereotypes. Their lack of inclusiveness is due to having had to overcome a situation of “double jeopardy” (Almquist, 1975) when building a career in STEM, being both members of an ethnic minority and women in STEM. Majority Serb women have adopted masculine patterns of behavior, try to blend in, and become “one of the boys” (Powell and Sang, 2015) in order to diminish the gender penalty and be seen as equal to men. Both minority and majority women agreed that deeply rooted gender stereotypes prevent women from choosing a career in STEM and identified the need for more inclusive education programs at all levels and for more female role models in STEM.Originality/valueThe study contributes by increasing understanding of ethnic minority and majority women's issues in STEM studies in Serbia from an intersectional perspective. It may be relevant to policy makers and contribute to the development of policy recommendations that steer more women in general and ethnic minority women specifically toward STEM, with the ultimate goal of enabling Serbia to develop not only socially but also economically. The paper contributes to the limited research on the STEM-related career experiences of ethnic minority Hungarian women and majority Serb women in Serbia and in the Western Balkans in general.
Two-layer nanofluid flow and heat transfer in a horizontal microchannel with electric double layer effects and magnetic field
Authors: Zhao Qingkai , Xu Hang , Tao Longbin 
Published: December 2020

Purpose
The purpose of this paper is to investigate the immiscible two-layer heat fluid flows in the presence of the electric double layer (EDL) and magnetic field. The effects of EDL, magnetic field and the viscous dissipative term on fluid velocity and temperature, as well as the important physical quantities, are examined and discussed.

Design/methodology/approach
The upper and lower regions in a horizontal microchannel with one layer being filled with a nanofluid and the other with a viscous Newtonian fluid. The nanofluid flow in the lower layer is described by the Buongiorno’s nanofluid model with passively controlled model at the boundaries. An appropriate set of non-dimensional quantities are used to simplify the nonlinear systems. The resulting coupled nonlinear equations are solved by using homotopy analysis method.

Findings
The present work demonstrates that increasing the EDL thickness and Hartmann number can restrain the fluid flow. The Brinkmann number has a significant role in the enhancement of heat transfer. It is also identified that the influence of EDL effects on microflow cannot be ignored.

Originality/value
The effects of viscous dissipation involved in the heat transfer process and the body force because of the EDL and the magnetic field are considered in the thermal energy and momentum equations for both regions. The detailed derivation procedure of the analytical solution for electrostatic potential is provided. The analytical solutions can lead to improved understanding of the complex microfluidic systems.
Marketing of vending channels: a case of French university campuses
Authors: Stoyanov Dobromir 
Published: December 2020

PurposeThis study identifies the conventional elements of the vending marketing mix and how they vary across academic segments in the context of a typical French university.Design/methodology/approachTo determine the elements of the vending marketing mix, the author conducts interviews with international industry experts and undertake 170 direct observations at various universities to verify the differences between the marketing mix proposals of dissimilar target markets.FindingsThe results reveal significant variances across all elements of the marketing mix, with distribution characteristics being the most frequently adapted element across various markets, followed by promotion- and product-related parameters, while pricing characteristics are most commonly standardised.Research limitations/implicationsVending operators should pay particular attention to marketing decisions related to the product assortment length, selection of appropriate locations, availability of smart payment options and feedback communication channels. The results reveal significant variances across all elements of the marketing mix indicating that vending operators apply strategies to reach different market segments. However, there is a high degree of standardisation within vending channels.Originality/valueThough vending channels are an important retail format, prior studies do not investigate their marketing mixes. This is the first attempt to empirically establish the conventional elements of the vending marketing mix and to measure its variation across customer segments.
Theorising the impact of COVID-19 on the fraud victimisation of older persons
Authors: Cross Cassandra 
Published: December 2020

PurposeThe purpose of this paper is to understand how COVID-19 may alter the vulnerability levels of older persons, and how this may change their potential for fraud victimisation. This is particularly focused on the government’s use of isolation, restrictions on activity and physical distancing to combat the virus.Design/methodology/approachIn the absence of statistics, this paper examines what is currently known about older persons and fraud, as well as the recent knowledge of COVID-19-related fraud. On this basis, the paper hypothesises the conceivable changes to vulnerability that potentially expose older persons to fraud.FindingsThis paper argues that COVID-19 has not seen “new” fraudulent approaches, rather offenders have used COVID-19 as a context to their existing schemes. Further, the current response to COVID-19 can substantially increase the number of older persons experiencing levels of vulnerability, and therefore increase their fraud risk.Research limitations/implicationsThe current paper applies existing knowledge into the current circumstances of COVID-19 and lays the foundations for empirical work to be conducted in this area.Practical implicationsThis paper provides an impetus to target the well-being and connectivity of older persons, (regardless of the COVID-19 context), to reduce their vulnerability to fraud victimisation.Social implicationsThis paper highlights the importance of connectivity for older persons, and the need to focus on overcoming social isolation and loneliness.Originality/valueThis paper is the first to hypothesise the effects of COVID-19 and its associated government responses to the overall vulnerability of older persons, with a focus on the potential for fraud victimisation.
Brand addiction: brand characteristics and psychological outcomes
Authors: Francioni Barbara , Curina Ilaria , Hegner Sabrina M. , Cioppi Marco 
Published: December 2020

Purpose
This paper aims to empirically test the influence of brand characteristics on brand addiction, as well as the consumers’ behaviors caused by this construct.

Design/methodology/approach
The paper adopts a Web-based self-completion survey by achieving a total of 529 completed surveys. Then, structural equation modeling has been employed by using SPSS AMOS.

Findings
Results highlighted how the brand characteristics of self-expressiveness, innovativeness and authenticity have a positive influence on brand addiction; brand addiction leads consumers to feel emotions of irritability and to adopt obsessive and compulsive behaviors toward the brand.

Research limitations/implications
Even if the choice of using a survey’s sample composed of students attending an Italian University ensures good internal validity of research (owing to the homogeneous character), the results are not generalizable (except for this population group).

Practical implications
The study identified two different spheres of brand addiction (one connected to the brand’s characteristics and the other to the consumers’ psychological-behavioral outcomes), along with possible strategies firms could adopt to strengthen the possibilities to transform their customers into addicted ones and to avoid/reduce the negative consequences deriving from brand addiction.

Originality/value
The paper provides a response to the call for more studies into the brand addiction analysis by empirically testing possible antecedents and outcomes, thus enriching the existing quantitative research focused on this concept.
Classifying economics for the common good: a note on the links between sustainable development goals and JEL codes
Authors: Heikkilä Jussi T.S. 
Published: December 2020

PurposeThis brief note sheds light on the links between Journal of Economic Literature (JEL) codes and the Sustainable Development Goals (SDGs) of the United Nations.Design/methodology/approachThree alternative methods based on keyword overlap to establish links between SDGs and JEL codes are presented.FindingsThese simple linkages illustrate that the themes of SDGs have corresponding closely related JEL classification codes.Research limitations/implicationsThe mappings presented in this note are based on simple keyword overlap and are therefore necessarily imperfect and incomplete. There is plenty of room for further development.Practical implicationsDespite the demonstrated possibility of linking SDGs to existing JEL codes, introducing a specific JEL code for each SDG would reduce search costs for those searching for economic research related to specific SDGs.Originality/valueThe first and preliminary attempt to link SDGs and JEL codes.
The link between financial stress index and economic activity: prominent Granger causalities across frequencies in Luxembourg
Authors: Bahramian Pejman , Saliminezhad Andisheh , Aker Şule 
Published: December 2020

PurposeIn spite of the certain risk imposed by financial stress on the real economy, the relationship between financial stress and economic activity is complicated and underresearched, meaning that important gaps still remain in the authors’ understanding of this critical relationship. Therefore, the current study aims to answer the significant question regarding whether a stressful financial sector has predictive power on the real sector and vice versa. Hence, the study examines the causal interrelationship between financial stress index (FSI) and economic activity in Luxembourg as a sample country.Design/methodology/approachIn this study, accompanying the time domain Granger causality framework of Hacker and Hatemi-J (2012), the authors utilize the spectral causality technique of Breitung and Candelon (2006), which is based on the study of Geweke (1982) and Hosoya (1991). This method enables the researcher to measure the degree of a particular variation in time series. Moreover, it allows considering the nonlinearities and causality cycles. The authors further apply the recent method of Farné and Montanari (2018) that is a bootstrap framework on Granger-causality spectra, which allows for disambiguation in causalities.FindingsThe time-domain approach finds evidence of bidirectional causation between the variables. However, the spectral causality results indicate the causal linkages between the series are only valid under the medium-run frequency. This study’s findings emphasize covering the frequency causality to deliver a more comprehensive picture of the interrelationship between the variables.Originality/valueThere are many studies in this area that examine the nexus between financial stress and economic activity. However, the authors believe this paper is the first study in the context of Luxemburg. The authors focus on this country since its financial sector is designated as the most important pillar for the economy. Thus, a careful and reliable examination of the relationship between the financial sector and economic activity is likely to be of considerable interest to policymakers and researchers in this field.
The comprehensive framework for integrated healthcare implementation: a realist evaluation of positive parenting in rural primary care in the US
Authors: Moon Deborah J. , Ballard Adrian J. 
Published: December 2020

PurposeThis study aimed to develop a comprehensive framework that encompasses contextual determinants of integrated care implementation. The initial framework was developed based on literature and was refined based on contexts and mechanisms that facilitated or interfered with integrating a pilot parenting intervention, Behavior Checker (BC), into the routine service delivery in a rural primary care clinic in the USA.Design/methodology/approachThis study was a single organizational case study informed by the realist evaluation methodology. Data collection methods included key informant interviews, healthcare staff surveys, a focus group and direct observation of meetings. Data analysis focused on identifying the context-mechanism-outcome (CMO) frameworks, a heuristic used in a realist evaluation to map pathways of the interactions between program inputs and contextual conditions leading to intended and/or unintended outcomes.FindingsThe identified CMOs and antecedent contexts identified informed the process of revising the initial Comprehensive Framework for Integrated Healthcare Development and Implementation (CF-IHDI). The revised CF-IHDI contained six parent domains of outer setting, basic structures, people and value, intervention characteristics, organizational capabilities for change and key processes.Research limitations/implicationsThe CMOs and core characteristics of contextual conditions that activated facilitating mechanisms can inform future studies examining healthcare integration efforts.Practical implicationsThe CF-IHDI can guide primary care clinics in identifying factors and strategies to consider when integrating parenting or other psychosocial interventions into primary care routine service delivery.Originality/valueThe CF-IHDI developed in this study contributes to the knowledge of contexts and mechanisms that facilitate and interfere with integrated care implementation.
International donors as enablers of institutional change in turbulent times?
Authors: Vakulenko Veronika 
Published: December 2020

PurposeThe purpose is to explore the role of international financial institutions (IFIs) during public financial management reform in a transitional economy. In particular, the study focuses on interaction between external enablers and local actors.Design/methodology/approachThe paper is based on a qualitative study of public financial management reform in Ukraine during 1991–2014. This period is divided into stages corresponding with two projects financed by the World Bank: “Treasury System” and “Public Finance Modernization.”FindingsFirst, IFIs supported a Ukrainian economy weakened by financial crisis and insisted on a comprehensive reform of public financial management to facilitate recovery. By strategically addressing local challenges, eliminating local uncertainties and maintaining stable interactions, IFIs gained support from the central government. Local actors continued the reform by negotiating with other actors and getting quorum support. In the second stage, IFIs could not implement planned changes. Even though the change was well-perceived at the beginning, developed tensions between local actors were overlooked by IFIs, which resulted in loss of commitment of the State Treasury representatives. The continuous political instability in Ukraine constrained interaction between IFIs and the Ministry of Finance and reduced political will for conducting reforms.Originality/valueThe study contributes to the debate on the adequacy of externally driven public management reforms in developing countries by exploring actions and interactions of global and local actors during the change in public sector practices.
Education Briefing Property valuation: the hedonic pricing model: the application of search-and-matching models
Authors: Lisi Gaetano 
Published: December 2020

PurposeThe aim of this education briefing is to comment upon how basic hedonic pricing models for the valuation of property can be expanded and developed. In this case, the briefing illustrates the use of the new economic approach to the analysis of housing markets, namely the search-and-matching models.Design/methodology/approachThis education briefing discusses the connection of two important economic theories: the hedonic price theory and the search-and-matching theory.FindingsThis education briefing gives an example of a (non-linear) form of the hedonic price function.Practical implicationsIn cases of mass appraisals, hedonic pricing models can provide a broad indication of value across submarkets and this education briefing demonstrates a theoretical model that can be used to provide a theoretical groundwork for the use of a concave hedonic price function in empirical estimates.Originality/valueThis education briefing shows how basic hedonic pricing models can be enhanced by a search-and-matching approach to determine property values.
The effects of status on the performance of portfolio diversification strategies
Authors: Yu Hyekyung , Kim Tohyun 
Published: December 2020

PurposeThis paper investigates how a firm's status moderates the performance of its investment portfolio diversification strategy. We combine the investment diversification literature with the organizational status theory, arguing that status would weaken the benefits of a specialist strategy in their niche industry of investments while strengthening the positive consequences of a generalist strategy across various industries.Design/methodology/approachWe collected our data using the Securities Data Company (SDC) Platinum VentureXpert database. A fixed-effects spline regression analysis for 2,201 US venture capital firms between 1969 and 2016 was used to test for a nonlinear relationship between the level of portfolio diversification and firm performance.FindingsWe found that status differences exist in the performance of a specialist strategy but not in that of a generalist strategy. Our results indicate that portfolio specialization in fewer number of industries has little impact on low-status firms, whereas high-status firms suffer significantly lower IPO success rates. In contrast, above-median portfolio diversification was found to be beneficial to both high- and low-status firms.Originality/valueWe specifically identify the impact of status on the performance of investment diversification strategies, an area of research which has received little attention. Further, our findings provide some practical implications for managers making investment decisions between specialist and generalist investment strategies, given their status within the market. Implications for understanding the roles of firm status in portfolio diversification strategies are discussed.
Big data and academic libraries: is it big for something or big for nothing?
Authors: Tella Adeyinka , Kadri Kehinde Khadijat 
Published: December 2020

Purpose
The paper examined big data and academic libraries and emphasized whether it is big for something or nothing.

Design/methodology/approach
A conceptual and review analysis of documents was adopted to determine the concept of big data, the sources, the features, the relevance to academic libraries, specific case studies from around the world that have made use of big data, uses of big data in academic libraries, a review of best practices in the use of big data in academic libraries and the challenges.

Findings
The paper reports that although big data is indeed very big in academic libraries because there are evidences of its adoption and best practices in its use in academic libraries across the world, available challenges can render it big for nothing.

Research limitations/implications
This study is limited in terms of using literature review approach to discuss big data and academic libraries. The study is also limited in terms of focusing academic libraries and not taken other types of libraries into consideration.

Practical implications
The study has created awareness on the part of academic libraries stakeholders including authorities, librarians and users on the relevance of big data in academic and how big indeed it is in academic library landscape. The study also implied future related studies can borrow ideas from the current studies, which will inform whether an empirical evaluation is possible on the subject matter.

Originality/value
The paper is the original idea by the author, and it is to emphasize the relevance of big data in academic libraries and to prepare academic libraries that have not been tapping the opportunities of big data to get ready.
Sharing economy approach for the development of the organic food market in India
Authors: Dangi Neeraj , Narula Sapna A. 
Published: December 2020

PurposeThis paper explores the contextual relevance of sharing economy for the organic food market in an emerging economy like India.Design/methodology/approachCase study approach was used to collect empirical data from different types of organic food markets.FindingsOrganic food farmers markets compared to online and health food stores tends to facilitate sharing economy more since it helps them to build value, scale and trust. By sharing resources, skills and spaces, organic farmers markets have increased organic food availability, reduced its cost of certification and operation besides managing consumer trust. Subjective influence through social media and offline interaction reduces information asymmetry at zero marginal cost. Organic food producers/retailers can get a competitive advantage by tapping underutilized assets to create value and opportunities besides overcoming their demand and supply constraints.Originality/valueThe research offers a fresh perspective to the organic food sector, particularly in emerging economies like India. It could assist all stakeholders to overcome the current demand and supply challenges faced in organic food markets.
