Authors: Atasoy Eda , Bozna Harun , Sönmez Abdulvahap , Aydın Akkurt Ayşe , Tuna Büyükköse Gamze , Fırat Mehmet 
Published: May 2020

PurposeThis study aims to investigate the futuristic visions of PhD students at Distance Education department of Anadolu University on the use of learning analytics (LA) and mobile technologies together.Design/methodology/approachThis qualitative research study, designed in the single cross-section model, aimed to reveal futuristic visions of PhD students on the use of LA in mobile learning. In this respect, SCAMPER method, which is also known as a focused brainstorming technique, was used to collect data.FindingsThe findings of the study revealed that the use of LA in mobile can solve everyday problems ranging from health to education, enable personalized learning for each learner, offer a new type of evaluation and assessment and allow continuous feedback and feedforwards; yet this situation can also arise some ethical concerns since the big data collected can threaten the learners by interfering with their privacy, reaching their subconscious and manipulating them as well as the whole society by wars, mind games, political games, dictation and loss of humanity.Research limitations/implicationsThe research is limited with the views of six participants. Also, the sample of the study is homogeneous in terms of their backgrounds – their age range, their departments as PhD students and their fields of expertise.Practical implicationsThe positive perceptions of PhD students provide a ground for the active use of LA in mobile. Further, big data collected through LA can help educators and system makers to identify patterns which will enable tailored education for all. Also, use of LA in mobile learning may stimulate the development of a new education system including a new type of evaluation and assessment and continuous feedback and feedforwards.Originality/valueThe widespread use of mobile technologies opens new possibilities for LA in the future. The originality of this research comes from its focus on this critical point.
Accrual mispricing in the era of corporate governance reforms
Authors: Sun Lan 
Published: May 2020

PurposeThis study is primarily motivated by the increasing concern of the academic, practitioners, regulators and standard setters regarding the quality of earnings and financial reporting. The purpose is to investigate whether the accrual anomaly exists in Australia; whether the occurrence of the accrual anomaly is attributed to the discretionary accruals component stemming from managerial discretion; and the impact of corporate governance reforms on accrual mispricing.Design/methodology/approachThis study employs the Mishkin (1983) rational expectations test to examine whether the earnings expectations embedded in stock prices accurately reflect the differential persistence of earnings components. It also employs the hedge portfolio trading strategy to examine whether taking a long position in firms with low accruals and a short position in firms with high accruals will yield positive abnormal stock returns.FindingsThe results show that investors overestimate the persistence of accruals and underestimate the persistence of cash flows and subsequently, overprice the accruals and underprice the cash flows. The evidence of accrual mispricing is severe for the component of discretionary accruals. Nonetheless, the association between discretionary accruals and abnormal returns are weakened during the corporate governance reforms period.Research limitations/implicationsIt should be cautious to attribute the investors' ability to accurately price accruals and cash flows to the passage of corporate governance reform program. Despite there is control for firm size, book-to-market, PE multiple, growth and leverage, other macro-economic factors such as interest rates, inflation and GDP could potentially have an impact on stock returns.Practical implicationsThe passage of corporate governance reform program has increased the level of financial reporting disclosure and the monitoring of management, which subsequently improved accruals persistence and earnings quality. A direct practical implication is that investors should better understand the information in accruals for future earnings when the corporate disclosure environment is strengthened.Social implicationsThis study provides useful information to regulators, academics and investors interested in market efficiency and accrual mispricing. The results suggest that the reform of corporate governance is associated with more efficient prices. This may be of interest to the regulators who intend to improve earnings quality and financial reporting environment through the regulatory reform.Originality/valueTo test the accrual anomaly in the period of corporate governance reforms is particularly useful to regulators and policy makers. It allows regulators and policy makers to gain insight as whether the change of regulation has been effective – more transparent and timely reporting of financial information are supposed to help the investors to better understand the accruals and thus mitigate the potential for accrual mispricing.
Compaction effects on permeability of spherical packing
Authors: Zhang Duzhou , Tian Zhiguo , Chen Zhiqiang , Wu Dengyun , Zhou Gang , Zhang Shaohua , Wang Moran 
Published: May 2020

Purpose
The purpose of this paper is to investigate the evolution of the permeability of spherical packing during cold compaction by pore-scale modeling.

Design/methodology/approach
The discrete element method (DEM) is used to generate spherical packing structure under different compressive pressures and the Lattice Boltzmann method (LBM) is adopted to calculate the permeability of each spherical assembly.

Findings
It is found that the decrease of the porosity is the main reason of the reduction in permeability in the initial compression stage, but its influence becomes insufficient in the late compression stages. Besides, two empirical formulas are obtained, which describe the relation between the permeability and the equivalent mean diameter and the variation of normalized permeability with compressive pressure, respectively.

Research limitations/implications
In this study, the authors study the spherical particles and ignore the non-spherical effects. Besides, the classical contact model, the linear-spring-damping model, is used in DEM, so the plastic deformation cannot be considered.

Originality/value
The DEM and the LBM are well combined to study the compaction effects on permeability of spherical packing. Two simple expressions of the spherical packing structure with uniform diameter distribution are given for the first time.

Finally, the engineering practicality of the method is verified by field operation experiment, the effective implementation of this control method greatly improves the robot working efficiency and the operation reliability, the promotion and application of the control method have great theoretical and practical value and maintenance management system, so as to achieve automation of electric.
Conflict triggers between farming and pastoral communities in Nasarawa State, Nigeria
Authors: Tade Oludayo , Yikwabs Yikwab Peter 
Published: May 2020

Purpose
This study aims to examine contemporary factors underlying farmers and pastoralists’ conflict in Nasarawa state. These two communities had rosy and symbiotic relationships which have transmogrified into sour tales of mutual suspicion, destruction, deaths and violence.

Design/methodology/approach
Exploratory research design was used. Data was collected using qualitative tools of data collection such as in-depth interview (IDI) and key informant (KII) guides to extract responses from farmers and pastoralists.

Findings
In a bid to end the conflicts between these two groups, Benue State Government enacted the Open Grazing Prohibition and Ranches Establishment Law also known as anti-open grazing law in 2018. Although the law altered the conflict landscape in Benue, it recorded trans-territorial backlashes in the neighbouring Nasarawa State where herdsmen relocated. The relocation of herders to Nasarawa State, setting up of livestock guards to check open grazing by pastoralists, rumour and politics triggered contemporary violent conflicts between these groups.

Originality/value
As against existing studies, this study examines contemporary trigger of the conflict.
Preference for action: regulatory mode in B2B positioning decision-making
Authors: Kalafatis Stavros P. , Blankson Charles , Boatswain Marvyn Luxly , Tsogas Markos H. 
Published: May 2020

PurposeGrounded in regulatory mode theory (RMT), this study aims to investigate the impact of managers’ orientation for action (locomotion and assessment) in business-to-business positioning decision-making.Design/methodology/approachData are collected using a scenario-based experimental design. Study 1 examines whether interest and involvement in recommending a positioning strategy depends on a manager’s regulatory mode orientation. The impact of such orientations on the likelihood of changing a recommended positioning strategy is the focus of Study 2. The moderating effects of task motivation (expected rewards resulting from a recommendation), market feedback and the line manager’s leadership style are examined.FindingsBoth assessment and locomotion are significant determinants of involvement in recommending a positioning strategy. The introduction of motivation as a moderator helps explain differences in level of interest in positioning decision-making. Locomotion, but not assessment, affects the likelihood of changing a recommended positioning strategy. Assessment amplifies the impact of locomotion, while none of the interaction effects between regulatory mode orientation and contextual factors is a significant determinant of changing a positioning strategy.Originality/valueTo the best of the authors’ knowledge, this is the first application of RMT on positioning decision-making. Results from two experiments provide novel insights into the predictive relevance of managers’ preference in terms of involvement with the decision-making process and the likelihood of altering positioning.
Causes of U.S.-China trade imbalances: a review
Authors: Wang Yongqing 
Published: May 2020

Purpose
It is a common view to Trump administration and public that devaluation of Chinese currency is the origin of the US trade deficit. However, the previous literature does not support this common view. To better understand the causes of the US trade imbalances with China, this study aims to review the previous literature focusing on the causes of bilateral trade imbalances between the USA and China.

Design/methodology/approach
Review previous literature according to the different reasons that each paper studies.

Findings
Based on the previous literature, the Chinese exchange rate is not the main reason for the US trade imbalances. The official US trade figures overestimate the amount of deficit. The actual causes for the US trade deficit with China perhaps should be the relocation of production to China, low saving in the USA and high saving in China, and the US dollar as the international currency and reserve.

Originality/value
By reviewing previous literature, the authors could better understand the puzzle of the US trade deficit with China.
Order of justice in queues of emerging markets
Authors: Chatterjee Swagato 
Published: May 2020

Purpose
Extant literature on queuing has identified service queues as social systems where social justice is an important factor for service evaluation. First-order justice, defined as a first-come first-served (FCFS) process, has been found to be a necessary condition of social justice and positive evaluation. Second-order justice, defined as equal waiting time, has been found to be an additional factor which comes into play only when first-order justice is met. This paper aims to show that in the emerging market situation, the above definitions of justice and the order mentioned above does not work.

Design/methodology/approach
Instead of equal wait, the study has focused on equitable wait, i.e. waiting duration is in sync with the service needs. Three experiments have been performed to establish the hypotheses suggested.

Findings
FCFS is found not to be the necessary condition as it was in the extant literature and can be relaxed sometimes to get higher service evaluation by ensuring justice from the equitable wait. The study also portrays the interaction effects of the two types of social justice on service evaluation. Moreover, the impact of justice from equitable wait on service evaluations is found to be moderated by perceived personal connect of the service provider and the consumer, perceived importance of system and process and perceived ability of the service provider of capacity improvement and mediated by perceived control of service provider on providing the justice of equitable wait.

Research limitations/implications
The study contributes toward the understanding of social justice in service queues. It also contributes to the literature of attribution theory and consumer betrayal.

Practical implications
The study provides suggestions to retail managers in emerging markets to choose queue management strategies depending on the size of the retail shops and consumers’ expectations from them.

Originality/value
The study introduces the concept of justice from the equitable wait, which is original in the queuing literature to the best of the author’s knowledge. The study also finds a new order of justice in the emerging market scenario.
Open economy macroeconomics of commodity price fluctuation, sectoral inter-linkage and employment
Authors: Basu Moumita , Nag Ranjanendra Narayan 
Published: May 2020

PurposeThis is a theoretical paper in the field of structuralist macroeconomics. The paper focuses on commodity price fluctuation which has emerged as one of the major macroeconomic factors with significant bearing on the relationship between the agricultural and nonagricultural sectors.Design/methodology/approachThe paper develops a dual economy model consisting of an agricultural sector and an industrial sector. The commodity price is subject to the fluctuations due to the fact that stock of primary goods is an asset which is sensitive to speculations. The paper considers a standard methodology of dynamic adjustment process involving change in stock of agricultural goods and price of agricultural goods under perfect foresight. The saddle path properties of the equilibrium are also examined.FindingsThe paper shows that the balanced budget fiscal expansion, capital account liberalization and the agricultural expansion lead to expansion of the industrial sector as well as level of employment. The increase in world interest rate may lead to contraction of the industrial sector and depress employment.Originality/valueWe will consider the openness of the economy in explaining how different macroeconomic policies and capital account liberalization generate multiple cross effects on the inter-connectedness between agricultural and the non-agricultural sector. The paper will discuss the issue of employment generation in conjunction with commodity price fluctuation. We depart from the literature by using Taylor rule under which interest rate is fixed by the Central Bank such that money supply becomes endogenous.
Disruptive life event or reflexive instrument? On the regulation of hospital mergers from a quality of care perspective
Authors: de Kam David , van Bochove Marianne , Bal Roland 
Published: May 2020

PurposeDespite the continuation of hospital mergers in many western countries, it is uncertain if and how hospital mergers impact the quality of care. This poses challenges for the regulation of mergers. The purpose of this paper is to understand: how regulators and hospitals frame the impact of merging on the quality and safety of care and how hospital mergers might be regulated, given their uncertain impact on quality and safety of care.Design/methodology/approachThis paper studies the regulation of hospital mergers in The Netherlands. In a qualitative study design, it draws on 30 semi-structured interviews with inspectors from the Dutch Health and Youth Care Inspectorate (Inspectorate) and respondents from three hospitals that merged between 2013 and 2015. This paper draws from literature on process-based regulation to understand how regulators can monitor hospital mergers.FindingsThis paper finds that inspectors and hospital respondents frame the process of merging as potentially disruptive to daily care practices. While inspectors emphasise the dangers of merging, hospital respondents report how merging stimulated them to reflect on their care practices and how it afforded learning between hospitals. Although the Inspectorate considers mergers a risk to quality of care, their regulatory practices are hesitant.Originality/valueThis qualitative study sheds light on how merging might affect key hospital processes and daily care practices. It offers opportunities for the regulation of hospital mergers that acknowledges rather than aims to dispel the uncertain and potentially ambiguous impact of mergers on quality and safety of care.
Challenges and opportunities for women entrepreneurs in Botswana: revisiting the role of entrepreneurship education
Authors: Rudhumbu Norman , du Plessis EC (Elize) , Maphosa Cosmas 
Published: May 2020

Purpose
The purpose of this paper is to investigate challenges faced by and opportunities open to women entrepreneurs in Botswana and how entrepreneurship education can boost their knowledge and skills of doing business profitably and contribute to women empowerment.

Design/methodology/approach
In total, 400 women entrepreneurs of different ages, educational levels and from trades and different geographical locations were selected using a stratified random sampling procedure to participate in the study from ten towns and cities in the country. A structured questionnaire that used a five-point Likert scale was used for data collection. One-way ANOVA, regression analysis and descriptive statistics were used as tools for data analysis.

Findings
Findings showed that women entrepreneurs faced a complex web of challenges among which were access to finance, lack of training leading to lack of technical skills, lack of knowledge of sources of financing and technical support, high competition in the market, marginalisation of women and lack of knowledge of marketing strategies. The key findings were that while women entrepreneurs faced a number of challenges, the legal and regulatory environment in Botswana was highly conducive and supportive of women entrepreneurship and also that customised entrepreneurship education and training offered opportunities for women entrepreneurs to enhance their knowledge and technical skills.

Research limitations/implications
The study only used a quantitative approach to collect data. It could have perhaps been more enriching if a mixed-methods approach were used to help probe the participants more. The study also only used women entrepreneurs in cities and towns. Perhaps, it could have also got some women entrepreneurs from rural areas to hear what they say. These limitations will be addressed in future studies.

Practical implications
Practical implications of the study are that women entrepreneurs need more training in business entrepreneurship for them to gain more knowledge and skills; finance houses become more accommodating to women entrepreneurship they could help in the empowerment of these people as they show potential in their businesses; and if more pro-women entrepreneurship policies are developed, they could enhance the activities of women entrepreneurs.

Social implications
Women can perform as much as men in business if given the necessary support.

Originality/value
This study contributes to the body of knowledge on women entrepreneurship as it helped expose challenges women entrepreneurs face as well as opportunities for them to take advantage of and improve their business operations.
