Mixed convection stagnation point flow of a hybrid nanofluid past a vertical flat plate with a second order velocity model
Authors: Roşca Alin V. , Roşca Natalia C. , Pop Ioan 
Published: April 2020

Purpose
The purpose of this study is to describe the steady mixed convection stagnation point of a hybrid nanofluid with a second-order velocity slip.

Design/methodology/approach
Using appropriate similarity variables, the partial differential equations are transformed into ordinary (similar) differential equations, which are numerically solved using the bvp4c function in MATLAB. The numerical results are used to present graphical illustrations for the reduced skin friction, reduced Nusselt number, velocity and temperature profiles.

Findings
Dual solutions are discovered in this study. Thus, stability analysis is implemented and the first (upper branch) and second (lower branch) solutions are determined and analyzed.

Research limitations/implications
Hybrid nanofluids have many practical applications in the modern industry such as in micro-manufacturing, periodic heat exchanges process, nano drug delivery system and nuclear reactors.

Originality/value
Despite numerous studies on the mixed convection stagnation point of classical viscous fluids past a vertical plate flow, none of the researchers have focused on the effect of second-order slip velocity on hybrid nanofluids. The behavior of the flow and heat transfer has been thoroughly analyzed with the variations in governing parameters such as heat source/sink and nanoparticle volume fraction. Moreover, the use of the wall slip velocity in this hybrid nanofluid model strengthened the novelty of this study.

Influence of structure and stretch on air permeability of compression knits
Authors: Muraliene Laima , Mikucioniene Daiva 
Published: April 2020

PurposeAir permeability has a valuable role in comfort parameters. It is known that air permeability of elastomeric yarns is firmly low. Despite that, usage of elastomeric inlay-yarns is the most common and the most effective way to generate compression for knitted textile. This study aims to investigate the influence of elastomeric inlay-yarn linear density, insertion density and elongation of the sample to the air permeability of compression knitted materials.Design/methodology/approachTwo different types of knitting patterns were investigated: rib 1 × 1 pattern with different elastomeric inlay-yarn linear density (four variants) and insertion density (without inlay yarn and with inlay-yarns inserted into every single, second or fourth course) and combined laid-in jacquard pattern. The air permeability test for these structures was performed without any deformation and at 10 and 20 per cent fixed transverse elongation.FindingsAccording to the investigation, insertion density of inlay-yarns has a huge impact on air permeability; however, air permeability of knitted material is not linearly proportional to the total amount of inlay-yarns. Also, it was found that air permeability increases by increasing elongation, regardless of knitting pattern and total amount of elastomeric inlay-yarn in the knitted structure. Alteration of the loop geometry at natural state and 20 per cent fixed elongation was established, and the increase of air permeability at fixed elongation may be dependent on changes of knitted material porosity.Originality/valueAccording to the obtained results, recommendations to perform air permeability measurement at least with minimal specific wear elongation are presented.
How useful is each item in the Sport Spectator Identification Scale?: an item response theory analysis
Authors: Kim Kyungyeol Anthony , Lee Senyung , Byon Kevin K 
Published: April 2020

PurposeThe purpose of this study is to evaluate the psychometric properties of each item in the Sport Spectator Identification Scale (SSIS) (Wann and Branscombe, 1993) using the item response theory (IRT) and to provide evidence for modifications in the scale.Design/methodology/approachA total of 635 spectators of US professional sports responded to the seven-item SSIS on an eight-point semantic differential scale. The general partial credit model was fitted to the data.FindingsThe results revealed that four items (Items 1, 2, 3 and 5) provide a relatively high amount of information, whereas three items (Items 4, 6 and 7) provide a low amount of information, indicating different levels of measurement precision among the items. Furthermore, the results showed that some low-level response options were rarely selected by participants, indicating that it may not be necessary to include response options as many as eight within each item.Originality/valueUnlike previous studies examining the psychometric properties of the SSIS as a whole, the present study provides information about the usefulness of each item of the SSIS in measuring individuals' team identification. Based on the findings, the authors identified some issues with the three problematic items, including the wording of the items and the link between the question and the target construct. The authors make several suggestions for researchers and practitioners in improving individual item quality and in making informed decisions when using the SSIS in the future.
Firms’ reaction to threats from informal firms: exploring the roles of institutional quality and technical gap
Authors: Qi Guoyou , Zou Hailiang , X.M. Xie , Zeng Saixing 
Published: April 2020

PurposeThreats from the informal sector have become an important concern among formal firms. As a response to these threats, formal firms can adopt product innovation (PI) and marketing innovation (MI) strategies to differentiate themselves. The purpose of this paper is to examine how firm-level technical capability and external institutional quality affect firms’ reactions to the threats from informal firms by adopting innovative activities.Design/methodology/approachBased on attention-based view (ABV), an empirical study is conducted by using firm-level data from the World Bank Enterprise Survey in 2013.FindingsThe findings indicate that when faced with competition from informal firms, formal firms will intensify their innovation activities in both MI and PI, and their technical capability mitigates the competitive threats from informal sectors and thus weakens the impact of informal competitors on the level of product and marketing innovations. Moreover, it is found that the improvement of institutional quality reduces formal firms’ urgency to introduce new products when facing informal competitors. However, this improvement strengthens the impact of informal rivalry on formal firms’ innovation in marketing methods.Originality/valuePrevious studies that investigate the influence of informal threats are focused on technological innovation (e.g., PI and process innovation) strategies, but little knowledge is provided on non-technological innovative strategies, such as marketing strategies (e.g., MI and organizational innovation). This study contributes to the innovation literature by delving into the circumstances under which PI and/or MI is adopted to counter informal rivals. The findings enrich ABV by investigating how inter-firm resource similarity and marketing commonality strengthen top managers' attention to competition from informal firms.

Authors: Saeed Maryam 
Published: April 2020

PurposeThis study aims to test the mediating role of psychological contract (PC) in a relationship between personality dimensions and turnover intention.Design/methodology/approachThe current study is analytical in nature. The data for the purpose of the analysis is collected from 300 software engineers working in Lahore, Punjab. Purposive sampling technique is used for the collection of this data. The response rate was 87.33 per cent. Different data analysis techniques such as correlation, regression analysis, are used to test the 10 hypotheses of the study. Moreover, the study adopted a cross-sectional survey design.FindingsAccording to regression analysis, extroversion, conscientiousness and agreeableness personality dimensions brought positive but insignificant increments in turnover intention. However, emotionally stable personality dimensions brought positive and significant increments in turnover intention. Open to experience personality dimension brought negative but insignificant decrement in turnover intention. Results showed extroversion personality dimension brought a very less but insignificant increment in variations of PC, which have higher contributions in variations of turnover intention. Emotional stable, conscientiousness and agreeableness personality dimensions brought also very less but a significant increment in PC. Open to experience personality dimension have negative but insignificant decrement in PC. Results showed the mediation impact of PC among emotional stability, conscientiousness and agreeableness personality dimensions and turnover intention. However, PC does not mediate among extroversion, open to experience personality dimensions and turnover intention. The paper concludes with recommendations for further research.Originality/valueThis study will help the organization in reducing the turnover rate and can enhance the motivation level of their employees.
Corruption in business
Authors: Begum Afroza 
Published: April 2020

Purpose
This paper aims to critically analyse the Criminal Code Amendment (Bribery of Foreign Public Officials) Act 1999 and Crimes Legislation Amendment (Combating Corporate Crime) Bill 2017 with special focus on the facilitation payment (FP) defence by referring to the UK Bribery Act 2010. The study will showcase how FP promotes disrespect for a good corporate culture inevitable for responsible and sustained business and as to why FP must be abolished to make the Australian regulation consistent with the international standards.

Design/methodology/approach
This research is based on primary and secondary sources including the Senate Committee Reports and recent legislative developments in Australia, and the relevant law of the UK.

Findings
Australia is lagging far behind comparative jurisdictions including the UK, and the FP defence must be abolished to make the Australian regulation consistent with the international standards and to foster international business backed up by globalisation, competition and interconnectedness of national economies.

Exploiting trust for financial gain: an overview of business email compromise (BEC) fraud
Authors: Cross Cassandra , Gillett Rosalie 
Published: April 2020

Purpose
This paper aims to explore current knowledge of business email compromise (BEC) fraud, or approaches that specifically target organisations for financial gain, through the exploitation of trusted relationships. BEC fraud affects organisations globally and is estimated to have netted offenders over US$26bn since 2016. Despite the sheer magnitude of these losses, there is a dearth of academic research seeking to better understand this crime type, and prevent it from occurring.

Design/methodology/approach
This review summarises the known literature on BEC fraud. It uses a variety of academic and industry sources to ascertain the current state of knowledge, including how it is perpetrated, its impact (on businesses and individuals), how law enforcement have responded and its prevention.

Findings
This review highlights many gaps in knowledge surrounding BEC fraud. There has been a large focus on the technical aspects of BEC fraud, to the detriment of the human elements. Often, BEC fraud is successful through targeted and effective use of social engineering techniques and is able to overcome any technical solutions through the manipulation of personal relationships. Further, while the financial impacts of BEC fraud are obvious, there is no known research which has explored the non-financial harms of BEC fraud (across organisational and individual perspectives). With companies starting to (unsuccessfully) take legal action against those who have responded, there is a clear need to understand how organisations can better respond to incidents when they occur. Finally, there are gaps in knowledge on what is the best combination of both technical and human measures to prevent BEC fraud.

Research limitations/implications
This review is based on information presently available, and as indicated, there are significant gaps in what is currently known.

Practical implications
This review highlights the need to undertake research into the current gaps, with a view to improving best practice knowledge on prevention and response.

Social implications
Currently unknown, BEC fraud is posited to have significant impacts at both personal and collective levels. Increased knowledge of these non-financial impacts will improve how organisations respond to BEC fraud and how employees can be supported before and after an incident occurs.

Originality/value
Despite the magnitude of the problem, there is limited academic scholarship on BEC fraud. This literature review offers a summary of current knowledge and advocates a strong research agenda moving forward.
Effects of financial management practices on technical performance of building contractors in northeast Nigeria
Authors: Sa'eed Abdulmalik , Gambo Nuru , Inuwa Ibrahim Ibrahim , Musonda Innocent 
Published: April 2020

Purpose
The purpose of this study is to assess the effects of financial management practices of small-scale building contractors on the technical performance of the contractors in the northern part of Nigeria with international best practices. Previous studies argued that the technical performance of small-scale building contractors in developing countries is poor because of insufficient cash to acquire strategic resources at the outset of a project. This continues to pose a challenge to the sustainable development of the construction industry, particularly in developing countries like Nigeria. There is, therefore, a need to identify, assess and compare the effects of financial practices of the contractors with technical performance best practices.

Design/methodology/approach
The technical performance of each contractor was evaluated using a five-point Likert scale. This is used to obtain the mean technical performance levels of the contractors. A questionnaire survey was administered to the professionals in the industry who were selected by using a proportionate stratified random sampling technique. The contractors’ performance was compared using ANOVA with post hoc, and the effects of contractors’ financial management practices were determined using multiple regression analysis.

Findings
The results of this study indicated that the contractors in Nigeria were average technical performers and there were large effects of financial management practices on the technical performance of contractors in building projects.

Research limitations/implications
This study is limited to small-scale building contractors in northeast Nigeria. One of the implications of this study is that it provides the criteria for an evaluation of small-scale building contractors’ technical performance in Nigeria and other developing countries that faced similar problems.

Practical implications
The practical implications of this study are that it establishes the current level of contractors' technical performance and serves as an awareness of contractors' current financial practices.

Social implications
This study created bases for self-evaluation of contractors’ technical performance and competition among small-scale contractors in Nigeria for the enhancement of productivity particularly in rural areas for national development.

Originality/value
This study emanated from the government reports and past studies in the area of performance management based on the persistence of poor technical performance of small-scale contractors in the construction industry.

Published: April 2020

PurposeThe aim of this study was to compare the defined indicators of tuberculosis (TB) control program in the intervention and control prisons, after implementation of the national clinical protocol for TB and HIV management in Iranian prisons, suggesting active health service provision in all steps of service provision.Design/methodology/approachThis was quasi-experimental study conducted among inmates of two prisons in Iran. Great Tehran prison was purposively chosen as the intervention prison and Karaj prison was purposively chosen as control prison as well. Intervention and control prisons were compared in terms of the TB indicators within three periods (before intervention, during implementation and follow-up period) from October 2013 to June 2014.FindingsNumber of inmates with TB symptoms who underwent TB workup was four times more in intervention prison compared to control prison (9.3 vs 2.5 cases out of 1,000 inmates per month in the case prison compared to the control prison). Such difference was also significant in the intervention prison, comparing before and during the intervention period. The patient finding in case prison increased significantly after the intervention (223.6 vs 81.8 cases out of 100,000 inmates per year). The number of TB cases who received HIV testing increased from 50 to 100%.Originality/valueActive health service provision has significantly improved indicators in the intervention prison. The authors recommend implementation of this guideline in all prisons of Iran. Integration of other diseases with high burden among prisoners is also recommended in the active health services provision.
Distracted driving prevention: an analysis of recent UK campaigns
Authors: Diegelmann Svenja , Ninaus Katharina , Terlutter Ralf 
Published: April 2020

PurposeThe purpose of this paper is to analyze message features of fear appeals in current British road safety campaigns directed against mobile phone use while driving and to discuss barriers to explicit theory use in campaign message design.Design/methodology/approachThis message-centred research takes a qualitative content analytical approach to analyze nine British web-based road safety campaigns directed against mobile phone use while driving based on the extended parallel process model. Message content and message structure are analyzed.FindingsThere still exists a gap between theory and road safety campaign practice. The study reveals that campaigns with fear appeals primarily use threatening messages but neglect efficacy-based contents. Severity messages emerge as the dominant content type while self-efficacy and response efficacy are hardly represented. Fear appeal content in the threat component was mainly communicated through the mention of legal, financial and physical harm, whereas efficacy messages communicated success stories and encouragement. As regards message structure, the threat component always preceded the efficacy component. Within each component, different patterns emerged.Practical implicationsTo enhance efficacy in campaigns directed against distracted driving and to reduce the gap between theory and practice, social marketers should include messages that empower recipients to abstain from mobile phone use while driving. Campaigns should show recommended behaviours and highlight their usefulness and effectiveness.Originality/valueThis paper adds to limited research conducted on effect-independent message properties of fear appeals. It enhances understanding of fear appeal message features across the structure and content dimension. By discussing barriers to explicit theory use in social marketing practice and offering practical implications for social marketers, it contributes towards reducing the barriers to explicit theory use in campaign message design.

Published: April 2020

PurposePatients with chronic obstructive pulmonary disease (COPD) suffer from many health problems including poor sleep. This paper aims to evaluate the relationship between diet quality indices (DQIs) and sleep quality in COPD.Design/methodology/approachThe current cross-sectional study was carried on 121 COPD patients. Subjective quality of sleep was determined by Pittsburgh Sleep Quality Index (PSQI) and categorized into “poor” and “good” sleep quality. Dietary history was assessed by the DQIs. Disease status was categorized according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines.FindingsIn total, 103 men and 18 women with a mean age of 66.1 ±10.9 were studied. The subjects were categorized into four groups based on GOLD; 3.3% of subjects were at Stage 1, 38% in Stage 2, 38% in Stage 3 and 20.7% in Stage 4. In total, 38% of subjects were good, and 62% were bad sleepers according to PSQI score. There was no significant relationship between the severity of COPD and PSQI score. We observed a significant inverse relation between PSQI total score and Mediterranean diet (MED) scale, Healthy Eating Index (HEI)-2010 and HEI-2005 (p= 0.024, 0.037 and 0.024, respectively) in males.Originality/valueThis study showed a high prevalence of poor quality of sleep and sleep disturbances among COPD patients. There was an inverse association between PSQI and sleep disorders and DQIs scores in COPD patients. Regardless of the severity of airflow obstruction, poor diet quality may constitute a risk factor for sleep quality.
