Internships and engineering: beliefs and behaviors of academics
Authors: Matusovich Holly , Carrico Cheryl , Harris Angela , Sheppard Sheri , Brunhaver Samantha , Streveler Ruth , McGlothlin Lester Marlena B. 
Published: June 2019

PurposeInternships play an important role in the choices engineering students make about future career pathways though there is little research about the messaging students receive regarding internships from academics. This messaging is important because it can contribute to the expectations students set for internships which in turn influences the interpretation of the experience and sense of appropriateness of that particular career pathway. Situated in Expectancy X Value theory, the purpose of this paper is to examine the beliefs and behaviors of the academics with whom engineering students interact as related to internship experiences.Design/methodology/approachThe authors conducted and analyzed interviews with 13 career center employees and 14 academic advisers/faculty members across six demographically and geographically diverse schools. Interviews were coded, and within and across case patterns developed.FindingsAcross all six schools, interview participants believe internships are important for students with regard to three areas: enabling career discovery, providing opportunities for development of career skills and helping students with full-time job acquisition. However, participants describe few direct actions associated with these beliefs. The lack of recommended actions for making the most of the internship experience, despite a strong belief in their importance, is a major finding of this paper.Originality/valueThis study is original in that it examines an important perspective that is not often a focus of research related to internships: academic advisors, faculty or career center personnel. The multi-institution sample enhances the value of the study as commonalities were seen despite variation in schools, enabling recommendations useful to a variety of contexts.
Effect of viscous dissipation in stokes flow between rotating cylinders using BEM
Authors: Teleszewski Tomasz Janusz 
Published: June 2019

Purpose
The purpose of this paper is to apply the boundary element method (BEM) to Stokes flow between eccentric rotating cylinders, considering the case when viscous dissipation plays a significant role and determining the Nusselt number as a function of cylinder geometry parameters.

Design/methodology/approach
The problem is described by the equation of motion of Stokes flow and an energy equation with a viscous dissipation term. First, the velocity field and the viscous dissipation term were determined from the momentum equation. The determined dissipation of energy and the constant temperature on the cylinder walls are the conditions for the energy equation, from which the temperature distribution and the heat flux at the boundary of the cylinders are determined. Numerical calculations were performed using the author’s own computer program based on BEM. Verification of the model was carried out by comparing the temperature determined by the BEM with the known theoretical solution for the temperature distribution between two rotating concentric cylinders.

Findings
As the ratio of the inner cylinder diameter to the outer cylinder diameter (r1/r2) increases, the Nusselt number increases. The angle of inclination of the function of the Nusselt number versus r1/r2 increases as the distance between the centers of the inner and outer cylinders increases.

Originality/value
The computational results may be used for the design of slide bearings and viscometers for viscosity testing of liquids with high viscosity where viscous dissipation is important. In the work, new integral kernels were determined for BEM needed to determine the viscous dissipation component.
Numerical optimization methods comparison based on the CFD conduction-convection heat transfer case
Authors: Mlynarczyk Przemyslaw 
Published: June 2019

Purpose
In some types of industries, the best possible design, in terms of thermal and flow performance, determines the success or failure of the company. This applies, among others, to the sectional elements that form doors, windows or prefabricated building walls. The purpose of this paper is to show the possibilities and limitations of the different response surface methods for optimization in the case where natural convection phenomenon appears inside the sectional structures.

Design/methodology/approach
A three-layered wall with air gap is used as a cross-section heat flow model. Response surface algorithms for optimization, which can be found in commercial software, e.g. ANSYS/WORKBENCH, can help to optimize geometrical structure of components to achieve bigger or smaller heat flux value. In this paper, the optimization methodology of the design of experiments (DOE) and different response surface (RS) methods are used.

Findings
Optimal results obtained with the use of genetic aggregation, standard RS, Kriging, non-parametric regression and neural network methods are compared with direct CFD and analytical calculations. Different limitations and advantages of the RS methods make individual methods more appropriate for different issues. For a properly defined optimization problem, the heat flux value approximated for the optimal geometry agrees with the direct CFD simulations.

Practical implications
The presented investigations show how to use response surface optimization methods for thermal optimization of the sectional elements and their applications to obtain reliable results.

Originality/value
This paper presents the value of the use of RS methods in CFD-based geometry optimization. The study also shows that the RS optimization methods can approximate thermal properties under natural convection development conditions.
Published incidents and their proportions of human error
Authors: Evans Mark Glenn , He Ying , Yevseyeva Iryna , Janicke Helge 
Published: June 2019

Purpose
This paper aims to provide an understanding of the proportions of incidents that relate to human error. The information security field experiences a continuous stream of information security incidents and breaches, which are publicised by the media, public bodies and regulators. Despite the need for information security practices being recognised and in existence for some time, the underlying general information security affecting tasks and causes of these incidents and breaches are not consistently understood, particularly with regard to human error.

Design/methodology/approach
This paper analyses recent published incidents and breaches to establish the proportions of human error and where possible subsequently uses the HEART (human error assessment and reduction technique) human reliability analysis technique, which is established within the safety field.

Findings
This analysis provides an understanding of the proportions of incidents and breaches that relate to human error, as well as the common types of tasks that result in these incidents and breaches through adoption of methods applied within the safety field.

Originality/value
This research provides original contribution to knowledge through the analysis of recent public sector information security incidents and breaches to understand the proportions that relate to human error.
Theoretical perspectives on public entrepreneurship
Authors: Liddle Joyce , McElwee Gerard 
Published: June 2019

Purpose
The interest in entrepreneurship in the public sector is recognized as an emergent phenomenon in the field of entrepreneurship. Existing theoretical work is limited in helping understand how entrepreneurship in public agencies occurs. The paper aims to discuss this issue.

Design/methodology/approach
This is a conceptual paper which develops the literature.

Findings
Building on the work of Klein et al. (2010) this paper contributes to theoretical development by providing an overview of public sector entrepreneurship (PSE). Although, there are similar features shared by private and PSE, it is proposed that there are significant differences between them, particularly in that public sector enterprise can be seen as entrepreneurship without entrepreneurs.

Research limitations/implications
As a conceptual paper on PSE the literature is predominantly UK based.

Practical implications
This paper brings entrepreneurship from the periphery to the core of the theoretical debates, as it is an under-researched area. Moreover, theoretical development has implications for policy and practice as existing research is disparate.

Originality/value
The paper considers how entrepreneurship and enterprise in the public sector is formulated. The significance of the paper is to highlight the importance of public entrepreneurs in working alongside a multitude of stakeholders to deal with numerous global and internal environment forces ethically amongst on-going budgetary and fiscal constraints. The contribution is the highlighting of the difficulties and concerns when uniting the discourse of market-based entrepreneurship and the discourse of public sector service provision.
Crowdfunding: a systemic framework of benefits
Authors: De Luca Valerio V. , Margherita Alessandro , Passiante Giuseppina 
Published: June 2019

Purpose
Crowdfunding (CF) is a fast-developing and multifaceted phenomenon at the intersection of entrepreneurship, technology, finance and sociology. Although it is an alternative way to fund innovative projects using the internet, CF can provide great value other than money. Nevertheless, only few studies have been conducted to shed light on such additional benefits. The purpose of this paper is to present an integrative model of benefits of CF for the successful undertaking and sustainability of an entrepreneurial initiative.

Design/methodology/approach
Based on a systematic review of literature, a preliminary taxonomy is first identified. Industry experts, campaign creators and the analysis of real cases are then used to progressively build a model of 11 areas and 85 categories of benefits deriving from CF.

Findings
The paper presents a comprehensive model of benefits of CF for the project, the start-up and the creator related to the following aspects: viability, costs, customer, demand, distribution, employees, fund, strategy, market, partners, personal, product.

Research limitations/implications
The study does not distinguish among different forms of CF. Besides, only benefits are studied whereas potential drawbacks and challenges are not considered. Further research is thus needed to complement the framework along such two additional areas of investigation.

Originality/value
The theoretical framework is an exhaustive snapshot of the benefits of a CF campaign and it can thus be assumed as a starting point for future and empirical studies. Moreover, the paper can support platforms managers in the design of values-added tools aimed to improve attractiveness and project creators in campaign design and management.
Relating entrepreneurial orientation with operational responsiveness
Authors: Sahi Gurjeet Kaur , Gupta Mahesh C. , Cheng T.C.E. , Lonial Subhash C. 
Published: June 2019

PurposePremised on dynamic capability theory, the purpose of this paper is to explore the link between entrepreneurial orientation (EO) and operational responsiveness (OR). In addition, grounded in contingency theory, the authors examine the roles of competitive intensity and technological turbulence in affecting the entrepreneurial orientation and OR link.Design/methodology/approachThis study proposes that firms’ entrepreneurial initiatives in terms of innovativeness, proactiveness and risk-taking significantly affect their responsiveness. Competitive intensity and technological turbulence moderate the EO and OR relationship. Using hierarchical regression analysis, the authors analyze the data generated from a sample of 164 small-and-medium enterprises in the USA.FindingsThe findings show that entrepreneurial initiatives are instrumental in responding to market requirements, which in turn results in superior performance. The authors also find that the interactive effects of innovativeness/risk-taking and competitive intensity are significant and positive, while those of innovativeness/proactiveness and technological turbulence on responsiveness are significant but negative. These findings imply that OR is effective when the level of competitive intensity is high while technological turbulence is low.Research limitations/implicationsThe authors conclude the paper by suggesting that entrepreneurial actions are pre-requisites for OR, which becomes effective only when the market experiences a moderate level of competition and a low level of technological change. The study provides implications for cross-functional research in the areas of entrepreneurship and operations management (OM) and also suggests future directions in this research stream.Originality/valueAlthough responsiveness has been recognized as a critical competitive capability in the OM literature, its relationship with EO is not fully understood and has not been empirically tested. Moreover, the interplay between EO and competitive intensity/technological turbulence and their effects on effective OR have not been gauged in the past.
Cross section of stock returns on Shari’ah-compliant stocks: evidence from Pakistan
Authors: Shaikh Salman Ahmed , Ismail Mohd Adib , Ismail Abdul Ghafar , Shahimi Shahida , Mohd. Shafiai Muhammad Hakimi 
Published: June 2019

Purpose
This paper aims to study the cross section of expected returns on Shari’ah-compliant stocks in Pakistan by using single- and multi-factor asset pricing models.

Design/methodology/approach
To estimate cross section of expected returns of Shari’ah-compliant stocks, the study uses capital asset pricing model (CAPM), Fama-French three-factor model and Fama-French five-factor model. Data for the period 2001-2015 on 217 companies are used. For the market portfolio, PSX-100 and Dow Jones Islamic Index for Pakistan are used.

Findings
The study could not find empirical support for CAPM using Lintner (1965), Black et al. (1972) and Fama and Macbeth (1973) approach. Nonetheless, the relation between beta and returns is positive in up-market and negative in down-market. The results of Fama-French three-factor and five-factor models suggest that size premium is positive and significant for explaining the cross section of stock returns of small size stocks, whereas value premium is positive and significant for explaining the cross section of returns of high value stocks.

Practical implications
The results suggest that fund managers can use Shari’ah-compliant stocks for portfolio diversification and for offering specialized investments given the positive market excess returns and the existence of size and value premium on Shari’ah-compliant stocks.

Originality/value
This is the first study on Fama-French (2015) five-factor model for Islamic capital markets in Pakistan.
Do fundamental portfolios outperform in the MENA equity markets?
Authors: Abadi Rasha Tawfiq , Silva Florinda 
Published: June 2019

PurposeThis study aims to investigate the performance of fundamental weighted portfolios (using sales, cash flows, dividends, book values and a composite of all these variables), an equal weighted portfolio and a smoothed cap-weighted (CW) portfolio in Middle East and North Africa (MENA) markets. The performance of these portfolios is compared with that of a CW portfolio for the period 2005 to 2015.Design/methodology/approachThe portfolios are formed using different concentration levels, different construction schemes and different sub-regions. The performance is assessed using a large set of risk-adjusted performance measures, including more robust measures in the context of multi-factor models, such as the Fama and French (1993) three-factor model, the Fama and French (2015) five-factor model and a seven-factor model.FindingsThe results show that the fundamental portfolios, with the exception of the sales portfolio, underperform the CW portfolio using either the traditional or more robust risk-adjusted performance measures. The underperformance of the fundamental portfolios is found to be robust using different concentration levels, different construction schemes and different sub-regions. The results also show that the equal weighted portfolio outperforms the CW portfolio using traditional risk-adjusted measures. However, after controlling for additional risk factors, this outperformance disappears.Practical implicationsThe failure of fundamental indexation in the emerging markets could help the researchers and the academics to search for the best weighting method that could be used as an alternative to the CW indexation method.Originality/valueThe results of the study add evidence to the debatable propositions on the performance of fundamental portfolios in emerging markets. Furthermore, the findings may help domestic and international investors, practitioners and decision-makers to deepen their knowledge in terms of the best portfolio construction scheme in the MENA region.
Support for smallholder farmers through Islamic instruments
Authors: Hossain Ishrat , Muhammad Aliyu Dahiru , Jibril Binta Tijjani , Kaitibie Simeon 
Published: June 2019

Purpose
In societies with strong presence of Islam, Islamic instruments with more scope for fairness and equity can be innovatively harnessed to play an increasing role in the development process and poverty alleviation schemes. Poor smallholder farmers dominate agricultural production in many developing countries and contribute a significant portion of global food production. This paper aims to develop a scheme to improve poor smallholder farmers’ vulnerable financial situation through the application of Zakah and Salam contract, using Bangladesh as a case study. Secondary goals are to show the effect of the scheme on food security and relevance to Nigeria.

Design/methodology/approach
The authors explore the existing traditional modes of financing available to poor smallholders, identify their challenges and propose an appropriate Islamic financing scheme.

Findings
With the Zakah-based Salam forward contract, the proposed scheme would procure food through Institutional Demand to offer interest free financing, fair price and access to new marketing channels and reduce income uncertainty for the rural smallholders. The discussions indicate that the local food security will be enhanced through incentivized farming activities and disbursement of food from the food bank to the Zakah-eligible food insecure local people.

Research limitations/implications
This proposal brings forth a potentially powerful idea that needs further empirical validation.

Originality/value
The religion-based Institutional Demand initiative to promote smallholder agricultural development and social protection is a novel one. The attempt to apply the framework to Nigeria context shows the potential of the framework to generalize for other Muslim developing countries with similar characteristics, especially the poorer agriculture-based countries.
Building institutional legitimacy in impact investing
Authors: Lehner Othmar M. , Harrer Theresia , Quast Madeleine 
Published: June 2019

Purpose
Impact investing denominates an investment logic that combines social and environmental goals, financial returns as well as personal values. The purpose of this paper is to consider the concept of legitimacy to be an appropriate way to understand how actors in the impact investing market influence discourse in order to overcome the inherent liability of newness – based on hybrid institutional logics – through their financial and non-financial communication.

Design/methodology/approach
Based on two theoretically defined sets of codes, a thematic discourse analysis is conducted by analysing meaningful units derived from documents produced by case-selected actors in the impact investing industry, which are then categorised into rhetorical strategies for legitimacy building.

Findings
The paper finds that actors use diverse legitimisation strategies based on their relative positioning in the impact investing market. These strategies determine the actors’ main discursive foci and, in turn, are affected by the overall organisational activities, governance and mission. This study proposes and discusses eight legitimacy creating strategies of relevant archetypes of impact investing actors in their financial and non-financial communication. Following these interconnected discursive engagements, a communication gap can be demonstrated between investors, intermediaries and social entrepreneurs.

Originality/value
Such discursive engagement gaps can provide a theoretical lens to explain the almost non-functional market and, as practical implications, show the need for convergence and harmonisation in financial and non-financial reports and communiques. This research further contributes to theory by providing insights into the discursive creation of legitimacy, and by promoting a better understanding of the emerging field of impact investing.
Interactive visualization of big data in the field of accounting
Authors: Perkhofer Lisa Maria , Hofer Peter , Walchshofer Conny , Plank Thomas , Jetter Hans-Christian 
Published: June 2019

PurposeBig Data introduces high amounts and new forms of structured, unstructured and semi-structured data into the field of accounting and this requires alternative data management and reporting methods. Generating insights from these new data sources highlight the need for different and interactive forms of visualization in the field of visual analytics. Nonetheless, a considerable gap between the recommendations in research and the current usage in practice is evident. In order to understand and overcome this gap, a detailed analysis of the status quo as well as the identification of potential barriers for adoption is vital. The paper aims to discuss this issue.Design/methodology/approachA survey with 145 business accountants from Austrian companies from a wide array of business sectors and all hierarchy levels has been conducted. The survey is targeted toward the purpose of this study: identifying barriers, clustered as human-related and technological-related, as well as investigating current practice with respect to interactive visualization use for Big Data.FindingsThe lack of knowledge and experience regarding new visualization types and interaction techniques and the sole focus on Microsoft Excel as a visualization tool can be identified as the main barriers, while the use of multiple data sources and the gradual implementation of further software tools determine the first drivers of adoption.Research limitations/implicationsDue to the data collection with a standardized survey, there was no possibility of dealing with participants individually, which could lead to a misinterpretation of the given answers. Further, the sample population is Austrian, which might cause issues in terms of generalizing results to other geographical or cultural heritages.Practical implicationsThe study shows that those knowledgeable and familiar with interactive Big Data visualizations indicate high perceived ease of use. It is, therefore, necessary to offer sufficient training as well as user-centered visualizations and technological support to further increase usage within the accounting profession.Originality/valueA lot of research has been dedicated to the introduction of novel forms of interactive visualizations. However, little focus has been laid on the impact of these new tools for Big Data from a practitioner’s perspective and their needs.
