The sexual orientation wage gap in the USA
Authors: Sayers Rachel , Levendis John , Dicle Mehmet 
Published: October 2017

PurposeThe purpose of this paper is to determine the nature of the wage gap between genders and sexual orientation.Design/methodology/approachThe paper uses OLS on pooled repeated cross-sections.FindingsThe differences in wages between gay/straight men and women mirror what would be expected from labor force attachment more so than direct heterosexism.Research limitations/implicationsThe authors use a functional definition of sexual preference that reflects whether the respondent had sex with someone of the same gender in the same year. It does not ask whether the person identifies publicly as gay/lesbian/bisexual.Originality/valueThe authors verify and extend earlier findings on the sexual orientation and gendered wage gap.
Did the time frame associated with the implementation of the Patient Protection and Affordable Care Act noticeably impact consumer bankruptcy filings?
Authors: Hackney Donald D. , Friesner Daniel , Johnson Erica H. 
Published: October 2017

Purpose
The purpose of this paper is to examine whether the timing associated with the implementation of the health insurance-related provisions of the Patient Protection and Affordable Care Act (ACA) altered the presence and distribution of medical/non-medical debts accumulated by different types of bankruptcy filers.

Design/methodology/approach
Data were drawn from the US Bankruptcy Court’s Eastern Washington District over the years 2009, 2011 and 2014 using interval random sampling. Binary probit and Tobit analyses were used to model the existence, and distribution, of medical debts and total debts, respectively, at the time of filing. The impact of the time frame associated with the ACA was operationalized via a Chow test for structural dynamic change.

Findings
Chapter 13 filers in 2014 (post-ACA-based health exchange implementation) were more likely to report medical debts than Chapter 7 filers in the pre-intervention period, and were also more likely to report a larger proportion of outstanding debts owed to a single creditor. Filers claiming health insurance premium expenses in 2011 were (at the 10 percent significance level) more likely to report a more skewed distribution of medical debts.

Originality/value
The time frame associated with the implementation of the ACA impacts the distribution of medical debts among filers who have sufficient net disposable income to fund a Chapter 13 plan. The polarization of outstanding medical debts may indicate coverage gaps in existing health insurance policies, whose costs would be disproportionately borne by patients operating on thin financial margins.
Determinants of household health expenditure in Nigeria
Authors: Olasehinde Noah , Olaniyan Olanrewaju 
Published: October 2017

PurposeThe purpose of this paper is to examine the determinants of health expenditure at the household level in Nigeria with specific focus on the household and individual unique characteristics. It presents some stylised facts about the Nigerian health system and its financing options. It went further to show that household is the major financial organ of healthcare in Nigeria. The study aims to expand the domain of household health expenditure by analysing at national, urban and rural levels.Design/methodology/approachIt adopted Engel curve approach, which was estimated using ordinary least squares technique. The model was structured to take care of life-cycle implications by examining effects of age in years and age groups (0-9, 10-19, 20-39, 40-59 and 60+) on healthcare spending. Data were drawn from the 2010 Harmonised Nigeria Living Standards Survey (HNLSS) conducted by the National Bureau of Statistics and analyses were conducted nationally, for urban and rural locations.FindingsThe result shows that individual characteristics like age, religion, education and household characteristics like income, size and headship commonly influence healthcare expenditure in Nigeria significantly. The household-level variables possess stronger significant effects among the rural households while marital status and employment had differential effects in both urban and rural locations. It also confirmed that Nigeria engages in intergenerational transfer of healthcare by the working population to the young and older generations.Research limitations/implicationsHNLSS was only limited to those who were sick or injured in the last two weeks preceding the survey, leaving out those whose sickness preceded the two weeks before the survey. Also, the scope of health expenditure is limited to curative care spending that exclude expenses on preventive care, rehabilitative care as well as other cost-saving services.Originality/valueThis paper fulfils an identified need to examine the determinants of household health expenditure at the national, urban and rural locations.
MovRec: a personalized movie recommendation system for children based on online movie features
Authors: Ng Yiu-Kai 
Published: October 2017

Purpose
The purpose of this study is to suggest suitable movies for children among the various multimedia selections available these days. Multimedia have a significant impact on the social and psychological development of children who are often explored to inappropriate materials, including movies that are either accessible online or through other multimedia channels. Even though not all movies are bad, there are negative effects of offensive languages, violence and sexuality as exhibited in movies. Parents and guidance of children need all the help they can get to promote the healthy use of movies these days.

Design/methodology/approach
To offer parents appropriate movies of interest to their youths, the authors have developed MovRec, a personalized movie recommender for children, which is designed to provide educational and suitable entertaining opportunities for children. MovRec determines the appealingness of a movie for a particular user based on its children-appropriate score computed by using the backpropagation model, pre-defined category using latent Dirichlet allocation, its predicted rating using matrix factorization and sentiments based on its users’ reviews, which along with its like/dislike count and genres, yield the features considered by MovRec. MovRec combines these features by using the CombMNZ model to rank and recommend movies.

Findings
The performance evaluation of MovRec clearly demonstrates its effectiveness and its recommended movies are highly regarded by its users.

Originality/value
Unlike Amazon and other online movie recommendation systems, such as Common Sense Media, Internet Movie Database and TasteKid, MovRec is unique, as to the best of the authors’ knowledge, MovRec is the first personalized children movie recommender.
Service composition in the multi cloud environment
Authors: Barkat Abdelbasset , Okba Kazar , Bourekkache Samir 
Published: October 2017

Purpose
User requests over the cloud are not achievable with one single service, multiple services need to be executed to fulfill what a user asks for. Typically, such services are composed and presented as one global service. Moreover, the same operation can be achieved by multiple services available at different clouds, which can result in different possibilities in composing them. This paper aims to decrease the number of clouds involved in the composition process, so that user requests are satisfied with minimal cost (communication costs, execution time and financial charges).

Design/methodology/approach
This paper investigates the use of an intelligent water drops (IWDs) optimization-based algorithm, and an integer linear programming model to optimize the number of cloud bases involved in the composition process. A comparison of the solutions found by these two techniques is presented in the paper.

Findings
The obtained results show that the number of cloud bases can be decreased without affecting user satisfaction.

Originality/value
The paper is a first attempt to use the IWDs algorithm for service composition, tested with big-size data.
Partial adjustment toward target accounts payable ratio
Authors: Abuhommous Ala’a Adden 
Published: October 2017

Purpose
This paper aims to test for a potential target accounts payable ratio and the determinants of accounts payable ratio.

Design/methodology/approach
The author use data from 104 firms over the period 2000-2014 and analyse these data using the system-generalised method of moments methodology.

Findings
The author find that Jordanian firms have a target accounts payable ratio and more than 65 per cent of the deviation from target is closed within a year. He find a positive impact of growth, positive growth and supply of credit on the accounts payable ratio. Furthermore, large firms use less trade credit to finance their purchases.

Research limitations/implications
A number of limitations affect this study to be considered in future research. Future researchers could cover longer period of time. To generalise the results, non-listed firms may be included in the sample.

Practical implications
In addition to extending the finance literature, this study has managerial implications regarding trade credit policy. There is strong evidence that the trade credit policy is affected by firm’s access towards capital market funds. Thus, regulators and policy maker should bear in mind that the banking system should help firms to achieve their target accounts payable ratio. In addition, firm’s management should be aware of the importance of trade credit to finance sales growth. All of these results should assist firm managers to find the factors that affect the target accounts payable ratio, which ultimately may affect the firm value and performance.

Originality/value
To the best of author’s knowledge, this is the first study on the partial adjustment model and determinants of accounts payable in Jordan. Thus, the authors aim to contribute to the existing literature, as there are very few studies test for target trade credit policy.
Doing social network ethics: a critical, interdisciplinary approach
Authors: Jones Simon 
Published: October 2017

Purpose
The purpose of this paper is to propose an inter-disciplinary approach to the ethics of social networking services (SNS) that connects critical analysis with the doing of ethics in terms of both pedagogic and technological practice.

Design/methodology/approach
Primarily conceptual and discursive, drawing on theoretical concepts from a broad, inter-disciplinary field. These concepts are integrated into a multi-dimensional framework that proceeds through four sequential stages: socio-economic, ethical, legal and practical/professional. Particular instances of SNS are used as illustrative examples.

Findings
The evaluation of ethical issues can be enriched by broader, holistic approaches that take account of the socio-economic, technical and legal contexts in which SNS technologies are designed, deployed and used. Inter-disciplinary approaches have the potential to generate new connections and possibilities for both the teaching and the professional practice of ethics.

Practical implications
Applied ethics are used to consider practical solutions that explore regulatory measures and envision alternative models of social networking. The approach proposed has practical value for teachers and students of computer ethics, as well as for IT practitioners.

Originality/value
This paper synthesises elements from media, communication and cultural studies, science and technology, information systems and computer science. The paper offers a strategy of inquiry to understand various aspects of SNS ethics – legal, socio-economic and technical. It presents a methodology for thinking about and doing ethics which can be used by IT practitioners.
The instructional factors that lead to cheating in a Korean cyber university context
Authors: Costley Jamie 
Published: October 2017

Purpose
This paper looks at a particular type of cheating that occurs in an online university setting. That is, when students who have a connection from outside the online learning environment conspire to cheat together. It measures the correlations between student variables and cheating, instructional variables and cheating and learning outcomes and cheating. The purpose of this paper is to understand the relationships between these factors and cheating, in the hope that the multifaceted nature of academic dishonesty can be better understood.

Design/methodology/approach
This study surveyed a group of students (n = 88) who participated in cyber university classes in South Korea. The study investigates the correlations between student characteristics, student attitudes, instructional design, lecture quality and learning outcomes with cheating.

Findings
The research looks at correlations between stable demographic factors and student attitudes towards cheating and finds no strong relationships. On the other hand, this study finds statistically significant negative correlations between instructional design quality and cheating, and lecture quality and cheating. This shows that instructors can affect the amount their students cheat through improving the quality of their courses. Also, there was a significant relationship between students’ levels of learning, satisfaction, engagement and interest and cheating.

Originality/value
Looking at cheating from a variety of angles within a single research agenda gives a clear understanding to instructors as to how cheating in their class will manifest, and how it will negatively impact the quality of a student’s experience.
Selected aspects and conditions of the use of robots in STEM education for young learners as viewed by teachers and students
Authors: Smyrnova-Trybulska Eugenia , Morze Nataliia , Kommers Piet , Zuziak Wojciech , Gladun Mariia 
Published: October 2017

Purpose
This paper aims to discuss issues related to science, technology, engineering and mathematics (STEM) education. It is emphasized that the need to prepare students with twenty-first-century skills through STEM-related teaching is strong, especially at the elementary level. The authors present selected previous experiences, publications, research into the study topic, and review examples of primary school robotics and programming curricula, as well as associated educational activities. The authors stress that workshops, using kits to build and programme robots, are a modern form of interdisciplinary education of children and youth.

Design/methodology/approach
The rationale for conducting such activities in schools is found in the European reference framework in the context of training of key competences. Classes in robotics – if properly taught – will have an impact on the development of mathematical literacy and scientific–technical information and social competences. At the same time, competence is understood to mean a combination of knowledge, skills and attitudes appropriate to the situation. Besides, an analysis is presented of basic legal regulations in this matter as well as results of a survey, conducted in Poland and Ukraine among in-service teachers and prospective teachers.

Findings
The study was carried out with the participation of 91 primary school teachers and future teachers in the province of Silesia and at the University of Silesia in Poland, and in Ukraine, at Borys Grinchenko Kyiv University. The survey contained 15 questions about the pedagogical research “Robotics and children”. The study was carried out to determine the needs of modern education to introduce the basics of robotics in the educational process of primary school.

Originality/value
It can be expected that the findings from the prior Polish and Ukrainian surveys can be extrapolated into curricula for secondary schools and vocational education and training (VET) in the coming years.
Picture-based persuasion in advertising: the impact of attractive pictures on verbal ad’s content
Authors: Kergoat Marine , Meyer Thierry , Merot Alain 
Published: October 2017

Purpose
The present study aims to further examine the persuasive effect of pictures in a print ad according to the recipient’s ability to process the information and to observe to what extent the presence of a picture could negatively influence recipients’ attitude toward the ad’s verbal claim.

Design/methodology/approach
Two studies were designed to manipulate the presence vs absence of an attractive/unattractive picture, the kind of verbal claims (affectively based vs rationally based) and the recipient’s ability to process the ad (cognitive load vs no cognitive load).

Findings
Main findings showed that the presence of an attractive picture elicited an unfavorable attitude toward the functional verbal claim when recipients were not cognitively charged. Furthermore, it proved to be a mediator of the influence of pictures on attitude toward the ad. The positive influence of an attractive picture on product evaluation and purchase intention was greater under a cognitive load but showed contrasting results for price perceptions. For the unattractive picture, cognitive load was found to be a moderator only when recipients had to infer the product price.

Research limitations/implications
The present research emphasized the negative influence of attractive pictures on functional verbal claims and the moderating role of cognitive load on pictorial stimuli either acting as peripheral or central cues in the persuasive process.

Practical implications
Practitioners may want to consider that an attractive picture in advertising is not always the best route for persuasion, especially when the verbal ad content emphasizes the product’s properties.

Originality/value
The present study provides new insights regarding the role of pictures in advertising persuasive effectiveness. Until now, no research had addressed the extent to which the presence of a picture could affect processing of an ad’s verbal claims. Additionally, the present study expands research on persuasive communication and affirms the necessity of more intensively investigating the role of pictures in advertising under the rubric of information processing level.
Default prediction using balance-sheet data: a comparison of models
Authors: Behr Andreas , Weinblat Jurij 
Published: October 2017

Purpose
The purpose of this paper is to do a performance comparison of three different data mining techniques.

Design/methodology/approach
Logit model, decision tree and random forest are applied in this study on British, French, German, Italian, Portuguese and Spanish balance sheet data from 2006 to 2012, which covers 446,464 firms. Because of the strong imbalance with regard to the solvency status, classification trees and random forests are modified to adapt to this imbalance. All three model specifications are optimized extensively using resampling techniques, relying on the training sample only. Model performance is assessed, strictly, based on out-of-sample predictions.

Findings
Random forest is found to strongly outperform the classification tree and the logit model in almost all considered years and countries, according to the quality measure in this study.

Originality/value
Obtaining reliable estimates of default propensity scores is of immense importance for potential credit grantors, portfolio managers and regulatory authorities. As the overwhelming majority of firms are not listed on stock exchanges, annual balance sheets still provide the most important source of information. The obtained ranking of the three models according to their predictive performance is relatively robust, due to the consideration of several countries and a relatively long time period.
Family firms and corporate social responsibility: exploring “concerns”
Authors: Lamb Nai Hua , Butler Frank , Roundy Philip 
Published: October 2017

PurposeScholars are devoting increasing attention to understanding a specific type of strategic initiative in family firms: corporate social responsibility (CSR). Prior studies have focused on the strengths of family firms’ CSR performance. However, to more fully understand family firms and their engagement in CSR, a granular approach is needed that teases apart the strengths and concerns of CSR performance and examines the specific dimensions that comprise CSR performance. Thus, the purpose of this paper is to theorize about six negative (i.e. concern-oriented) dimensions of family firms’ CSR performance.Design/methodology/approachTo examine the interrelationship between a firm’s percentage of family ownership and its CSR concerns, a sample of 71 public firms from Fortune 500 companies was constructed. The sample includes 13 years of firm-level data spanning 1994-2006 and represents over 600 firm-year observations.FindingsAs predicted, a higher percentage of family owners’ equity is positively related to diversity-oriented CSR concerns and negatively related to employee relations and environmental CSR concerns. However, the percentage of equity owned by family members is not associated with community, product quality and safety, and corporate governance CSR concerns.Originality/valueThe paper addresses substantive omissions in existing research on the influence of family ownership on CSR performance.
Time and space in business: dynamic geographic concentration and localized industry life cycle
Authors: Wang Liang 
Published: October 2017

PurposeThe purpose of this paper is to theorize how the industry life cycle unfolds differently across places and how economic agglomeration varies over time.Design/methodology/approachThe paper relies on literature review and conceptual analysis.FindingsIt generates a dynamic geographic concentration model (i.e. an industry’s degree of geographic concentration drops in the growth stage, rises in the mature stage, and drops again in the new growth stage) and a localized industry life-cycle model (i.e. temporal dynamics differ between the center and the periphery).Originality/valueIt makes contribution by theorizing that the extent to which an industry is geographically concentrated changes over time, and by demonstrating how an industry’s center and periphery may experience different temporal dynamics.
