What promotes smartphone-based mobile commerce? Mobile-specific and self-service characteristics
Authors: Choi Sujeong 
Published: December 2017

Purpose
Given that smartphones are widely used as a key means for mobile commerce, the purpose of this paper is to provide in-depth understanding of determinants of the utilitarian value that customers seek to obtain from using smartphone-based mobile commerce. Drawing on the technology acceptance model (TAM), the study proposes that usefulness and ease of use are two typical factors representing utilitarian value and verifies their impacts on smartphone-based m-commerce use. Moreover, the paper expands the TAM by considering mobile-specific characteristics (i.e. service ubiquity and location-based service (LBS)) and a self-service technology (SST) characteristic (i.e. user control) as determinants of utilitarian value.

Design/methodology/approach
The study entailed conducting a survey, and analyses were conducted based on a total of 379 responses from undergraduate and graduate students who had experience using smartphones for mobile commerce. The analyses used structural equation modeling to test the research model and hypotheses.

Findings
First, in the context of the various technologies-involved m-commerce, TAM serves as a theoretical lens to predict user behavior. Second, usefulness is greatly increased by service ubiquity, LBS, and user control. Third, ease of use is enhanced by service ubiquity and user control. Finally, ease of use is a determinant of usefulness.

Originality/value
The findings imply that mobile-specific and SST characteristics are the key determinants of utilitarian value in performance-oriented mobile commerce, and utilitarian value is a key determinant of smartphone-based mobile commerce use.

PurposeThe purpose of this paper is to analyze the organizational impacts of enterprise mobility and the configurations of mobile information technology (IT) impacts in companies with various value creation logics.Design/methodology/approachAn exploratory approach combining semi-structured interview and repertory grid method was used to evaluate managers’ perspectives on the effects of mobile technologies.FindingsThe qualitative findings unearth managers’ perspectives about the organizational impacts of enterprise mobility, which are categorized into six intermediary dimensions and two fundamental impacts. A further analysis of material collected from interviews also shows the differential context-related configurations of mobile IT impacts in companies.Research limitations/implicationsThis study contributes to literature on the business value of IT in general and mobile IT in particular by examining managers’ cognitive constructions of the organizational impacts of enterprise mobility and highlighting the complexity and context-related variety of mobile IT impacts.Practical implicationsThis study provides valuable insights for managers and decision makers that enterprise mobility shows promise in enhancing a firm’s operational and marketing performance.Originality/valueDifferent from prior literature, this study is an exploratory attempt to investigate complex enterprise-mobility-performance relationship and preliminarily uncovers that the mechanisms with which mobile IT influences firm performance vary in different organizational contexts.
Examining the impact mechanism of social psychological motivations on individuals’ continuance intention of MOOCs
Authors: Shao Zhen 
Published: December 2017

PurposeThe purpose of this paper is to examine the impact mechanism of psychological motivations, social influence and institutional influence on individuals’ continuance intention of MOOCs, and further, to explore if there exist behavioral differences between males and females.Design/methodology/approachDrawing on the social cognitive theory (SCT) and the technology acceptance theory, this study developed a theoretical model and conducted an empirical study in China. In total, 247 valid data were collected from college students using online survey, and the structural equation modeling technique was used to examine the research model.FindingsThe empirical results suggest that self-efficacy, self-enjoyment, self-development and social norm are positively associated with individuals’ continuance intention of MOOCs, while management commitment in the university has little influence on continuance intention. The moderating test further suggests that males are more likely to be influenced by self-development and perceived usefulness compared with females.Practical implicationsThis study can provide several guidelines to the administrators of the MOOC platform regarding platform design, course selection and social community establishment, so as to encourage more students to participate in the MOOC platform.Originality/valueThis study applied the SCT in the new context of MOOCs to examine the joint effects of social, institutional and psychological motivation factors on individuals’ continuance intention, and unpacks the moderating effect of gender.
Does college students’ social media use affect school e-mail avoidance and campus involvement?
Authors: Ha Louisa , Joa Claire Youngnyo , Gabay Itay , Kim Kisun 
Published: December 2017

Purpose
The purpose of this paper is to examine how college students’ social media use affects their school e-mail avoidance and campus involvement.

Design/methodology/approach
The study employed face-to-face interviews and self-administered survey/quantitative data.

Findings
Communication and business students are more involved on campus and likely to use social media as the primary communication medium than other majors. Social media and text messages are not the culprits of school e-mail avoidance. University departments, student organizations, and faculty advisors’ e-mails are most likely to be avoided. Social media users can be categorized as either “instant communicators” or “online content curators.” Facebook is the only social media brand conducive to campus involvement.

Research limitations/implications
This study only used one university’s students as sample. In examining school e-mail avoidance, it only focused on the source of e-mail. The study is limited by its sole reliance on quantitative behavioral data.

Practical implications
University administrators and academic advisors need to reconsider the e-mail communication to students, target at the instant communicator social media users, and use Facebook to create a strong sense of community and campus involvement for their students. Marketers can utilize the two social media user groups in selecting social media in targeting to students.

Originality/value
The study offered empirical evidence to explain how social media affect students’ school e-mail avoidance and the role of campus media and specific social media outlet on campus involvement. It advances the knowledge of media choice of students and the social media user groups.
Comparative study of Asian economies: lessons for India
Authors: Bhardwaj Mamta , Naosekpam Ajit Singh , Tewari Rupinder 
Published: December 2017

Purpose
This paper represents a comparative study of five Asian countries, namely, Singapore, Taiwan, South Korea, China and India, based on the Global Competitiveness Index (GCI) 2015-2016 published by the World Economic Forum. The purpose of this study is to assess India’s position vis-a-vis the various comparator Asian economies and to identify areas for improvement so as to enhance India’s competitiveness.

Design/methodology/approach
The study is based on the comparisons and analysis of the ranks of each country. These ranks are based on the indicators related to three categories, i.e. “Basic Requirements”, “Efficiency Enhancers” and “Innovation and Sophistication” Factors. The GCI included data from internationally recognised agencies such as the IMF, the WHO and the United Nations Educational, Scientific and Cultural Organization.

Findings
On the basis of the aforementioned comparisons among these five Asian economies, it was found that Singapore (Rank-2) has made stupendous economic progress and is amongst the top five successful economies of the world. Taiwan, South Korea and China also have taken significant economic strides and are ranked globally at 15, 26 and 28, respectively. India, on the other hand, is ranked 55 out of 140 nations.

Research limitations/implications
In this paper, the countries were compared on the basis of their rank in the GCI Report 2015-2016. For an in-depth and more holistic study, comparison can be done by taking into consideration other important reports and analysis in this regard.

Originality/value
This is an original study where the developments that have taken place in the five Asian economies have been analysed based on the GCI. Most importantly, this study identifies the area/indicator in which India needs to improve to be placed among the developed nations.
Sustainable development of agriculture: a system dynamics model
Authors: Bastan Mahdi , Ramazani Khorshid-Doust Reza , Delshad Sisi Saeid , Ahmadvand Alimohammad 
Published: December 2017

Purpose
Sustainable development is the management and conservation of the basic natural resources through which organizational and technological changes are lead to meet present and future needs of humans. In developing and analyzing the solutions based on sustainable development principles, an integrated and holistic approach needs to be pursued. Not only system dynamics has the essential tools for systemic analysis, but also it is an appropriate approach for perceiving problems and offering solutions. The aim of this study is to present an integrated and systemic model to analyze the existent dynamics in sustainable development of Iran’s farming industry.

Design/methodology/approach
To achieve the mathematical equations and values of model’s variables, a simulation is carried out using the data gathered from Damavand city, Tehran, Iran. The parameters of the model are selected and calculated considering the specifications of this case study. After modeling the system, Vensim simulation software has been employed, followed by identifying the leverage points of the model; then, a set of scenarios have been generated and tested through simulation to achieve a much improved understanding of the system’s dynamic behavior.

Findings
The results show that two factors are among the most important leverage points: “profit gained from agriculture” and “required water”. The authors could also observe that the main issue in Damavand is the lack of water for which saving policies would be a major step toward agriculture’s sustainable development in this area.

Originality/value
The paper shows how System Dynamics simulation approach can provide deep insights into the field of sustainable development and present efficient policies for agriculture sustainability.
Assurance for service organisations: contextualising accountability and trust
Authors: Channuntapipat Charika 
Published: December 2017

Purpose
A number of organisations outsource their information systems and information technology infrastructure to a type of organisation called a “service organisation”. In the current business environment, where cyber risks are increasing, it is important to have a mechanism to ensure the credibility of these service organisations. This paper, therefore, aims to understand the contextualisation of accountability and trust of related organisations through the use of assurance engagements.

Design/methodology/approach
This paper is conceptual in nature; however, textual data sources are used to support the theorisation of accountability and trust in the context of companies using service organisations. It uses publicly available assurance reports and related assurance standards for observing the accountability mechanism in practice, to understand the purpose of the assurance.

Findings
Assurance statements for service organisations mainly provide reputation-based, not contract-based, accountability. Limited access to the assurance reports and limited responsibility of service auditors potentially decrease the degree of this reputation-based accountability. The findings reveal a potential accountability paradox regarding the role of assurance practice, as to whether it serves as a managerial tool to build trust or as an accountability mechanism for stakeholders.

Originality/value
This paper extends the understanding of accountability and trust in the context of this unconventional form of organisational relationship. It urges more transparency in terms of the accessibility of assurance reports to provide information to wider stakeholders. The findings add to the latent literature on organisational trust and voluntary assurance practice.
Helping behaviors can negatively impact long-term well-being
Authors: Von Bergen Clarence W. , Bressler Martin S. , Boatmun Tim 
Published: December 2017

PurposeRecently, organizational scholars and social scientists began emphasizing the importance of compassion and altruism and called for increased demonstrations of assistance, giving, empathy and other prosocial conduct toward those in need. Generally, we assume that help is beneficial to those who receive it, and current research on these positive behaviors primarily focuses on the advantages to those who provide it. Despite recent calls for increased levels of aiding the needy and underprivileged, helping may have downsides and adaptive costs to those who receive support that are frequently overlooked. The purpose of the study is to bring to light the potential harm in helping those who lack commitment to improvement, having “skin in the game”.Design/methodology/approachIn addition to a literature review, the authors present a model to explain how support in response to human pain and suffering can sometimes result in negative effects on aid recipients. The model specifies two mechanisms, including participation of affected beneficiaries of assistance in the actual aid process and duration of help as factors that may expose vulnerable populations to more risk.FindingsThe literature strongly suggests that in some instances, helping can be detrimental, to the point where helping can even result in dependency. The authors do not suggest casting a blind eye to those in need, but rather to provide assistance that leads to self-sufficiency.Research limitations/implicationsAdditional research – especially over the long-term – can provide researchers with more detailed results of this approach.Practical implicationsThe findings of this paper can serve as a model approach to provide help that does not create dependency.Social implicationsUsing this approach could provide the ideal method to address long-term social issues that would break the cycle of dependency.Originality/valueThe authors believe that this approach to helping based upon the two-stage model could become the primary effective method for providing assistance to those in need without creating dependency in the long run.

Published: December 2017

PurposeThis paper aims to improve calibration and force measurement accuracy of multi-sensors’ piezoelectric dynamometer used in thrust measurement of rocket/air vehicle engine.Design/methodology/approachThis paper presents a mapping solution method of sensors’ outputs based on the Kirchhoff thin plate theory, builds force-deformation differential equations with specific boundary conditions, uses finite difference (FD) method to solve the equations and analyzes outputs in offset loading forces in four-sensor square layout in main direction. The resultant force deviations calculated by the Kirchhoff theory are optimized with sequence quadratic program (SQP) method, and a calibration method of multiple loading points (MLP) based on the Kirchhoff theory is presented. Experiments of static calibration and verification are complemented to contrast the novel and single loading point (SLP) calibration method.FindingsExperiments of static calibration and its verification show that at a loading force of 5,000N, the average resultant force deviations with MLP is 17.87N (0.35% FS) compared with single loading point method 26.45N (0.53% FS), improving calibration and measurement precision.Originality valueA novel calibration method with MLP is presented. Force distributions of multiple sensors of main direction in piezoelectric dynamometer with offset loading force are solved with the Kirchhoff theory. The resultant force deviations calculated by Kirchhoff theory are optimized with the SQP method.
‘Environment’ Submissions in the UK's Research Excellence Framework 2014
Authors: Thorpe Andy , Craig Russell , Tourish Dennis , Hadikin Glenn , Batistic Sasa 
Published: December 2017

AbstractThere has been much debate about university research assessment exercises. In the UK, a major element of the 2014 Research Excellence Framework (REF2014) has been the research environment. Here we analyse 98 REF2014 ‘environment’ submissions in Business and Management Studies. We explore whether there are distinctive language‐related differences between submissions of high and low ranked universities and conclude that submission writers have a strong incentive to exaggerate strengths and conceal problems. In addition, innate biases such as the ‘halo’ and ‘velcro’ effects may distract the attention of assessors from a submission's strengths and weaknesses, since they are likely to influence their pre‐existing impressions. We propose several changes to improve how environment is evaluated. We also argue that the research environment would be more likely to be enhanced if the number of outputs submitted in future was an average of two and a maximum of four per academic, rather than the maximum of five currently being considered.
Review article: NEXUS criteria to rule out cervical spine injury among older patients: A systematic review
Authors: Paykin Gabriel , O'Reilly Gerard , Ackland Helen , Mitra Biswadev 
Published: December 2017

AbstractThe National Emergency X‐Radiography Utilization Study (NEXUS) criteria were derived from a heterogeneous group of adult blunt trauma patients, with the outcome measure assessed most commonly using plain X‐ray radiographs. Recent observations have suggested inadequacy of these criteria for excluding injury in population subgroups such as the elderly. The aim of this systematic review was to determine the sensitivity of the NEXUS criteria in excluding cervical spine injury among older patients aged ≥65 years. A systematic review of the literature published prior to 1 January 2017 that reported on the performance of the NEXUS criteria among older patients was conducted. The databases OVID Embase and OVID Medline were searched. The sensitivity of the NEXUS criteria was recalculated for each study among older patients. There were seven studies included in this review. All studies were considered to be at risk of bias and rated down for quality of evidence. Emergency physicians were assessors in all included studies. Sensitivity of the NEXUS criteria among older patients ranged from 66% to 100%. Variable sensitivity was demonstrated when the NEXUS criteria were applied to older blunt trauma patients. This questions the applicability of the NEXUS criteria in this subgroup.
Modification of the Thrombolysis in Myocardial Infarction risk score for patients presenting with chest pain to the emergency department
Authors: Greenslade Jaimi H , Chung Kimberly , Parsonage William A , Hawkins Tracey , Than Martin , Pickering John W , Cullen Louise 
Published: December 2017

AbstractObjectiveTo develop a modified Thrombolysis in Myocardial Infarction (TIMI) score to effectively risk stratify patients presenting to the ED with chest pain.MethodsA prospective observational study was conducted at two metropolitan EDs. Data were obtained during patient interview. The primary outcome was major adverse cardiovascular events (MACE) within 30 days of presentation. Two separate modifications of the TIMI score were developed. These scores were compared to the original TIMI in terms of the area under the receiver operating characteristic curve and diagnostic accuracy statistics (sensitivity, specificity, positive and negative predictive values).ResultsOf 1760 patients, 364 (20.7%) experienced 30 day MACE. The first modified TIMI score was a simplified TIMI (s‐TIMI) including four variables: age ≥65 years, three or more risk factors, high‐sensitivity troponin (hs‐cTnI) and electrocardiogram changes. The second score included the same four variables plus two Global Registry of Acute Coronary Events (GRACE) variables (systolic blood pressure and estimated glomerular filtration rate). This score was termed the GRACE TIMI (g‐TIMI). s‐TIMI had a lower sensitivity compared to the original TIMI score (93.41 and 96.98%), but higher specificity (45.49 and 24.50%). The g‐TIMI had a sensitivity of 98.90% and specificity of 14.90%.ConclusionsAttempts to modify the TIMI score yielded two scores with added predictive utility in comparison to the original TIMI model. The addition of GRACE variables (g‐TIMI) increased sensitivity for MACE, but decreased the specificity of the model. The s‐TIMI score yielded good specificity but had sensitivity that would not be acceptable by emergency physicians. The s‐TIMI may be useful as part of an accelerated chest pain protocol.
Directors’ and Officers’ Liability Insurance and Aggressive Tax‐Reporting Activities: Evidence from Canada
Authors: Zeng Tao 
Published: December 2017

AbstractThis paper examines the relationship between directors’ and officers’ liability insurance (D&O insurance) and firms’ aggressive tax reporting. Using large Canadian public companies listed on the TSX300 and relying on several measures to capture aggressive tax‐reporting activities, including GAAP effective tax rates, cash effective tax rates, and the total and residual book‐tax differences, I find that D&O insurance exhibits a strong negative relationship with the GAAP effective tax rates and a strong positive relationship with both the total and residual book‐tax differences. However, there is generally no evidence showing that D&O insurance is associated with the cash effective tax rates. I interpret these results as indicating that D&O insurance reduces the tax expenses reported in the financial statements but not the actual tax paid. In other words, D&O insurance contributes to financial tax management but not to cash tax savings. Further tests in this study reveal that firms with fluctuating D&O coverage limits engage in more aggressive tax reporting than other firms, suggesting that managers may consider the level of D&O insurance that they purchase when they make aggressive tax‐reporting decisions.
