Fostering organizational learning through leadership and knowledge sharing
Authors: Park Sunyoung , Kim Eun-Jee 
Published: May 2018

PurposeThe purpose of this study is to examine the relationships among transformational leadership, knowledge sharing climate and behavior, interpersonal trust and organizational learning.Design/methodology/approachData from 209 participants from a manufacturing company in Korea were analyzed using the structural equation modeling method.FindingsThe findings of the study indicated that transformational leadership directly affected the knowledge sharing climate and behavior, interpersonal trust and organizational learning of an organization. Transformational leadership also indirectly affected organizational learning through knowledge climate and behavior, and interpersonal trust. In addition, a knowledge sharing climate directly affected interpersonal trust and knowledge sharing behavior and indirectly affected organizational learning through interpersonal trust and knowledge behavior. Interpersonal trust directly affected knowledge sharing behavior and indirectly affected organizational learning through knowledge sharing behavior. Finally, knowledge sharing behavior positively affected organizational learning.Research limitations/implicationsThe results highlight the important role of transformational leadership to enhance the knowledge sharing climate and behavior of employees, interpersonal trust and organizational learning. This study also indicated that transformational leadership, interpersonal trust and knowledge sharing behavior are antecedents of organizational learning.Practical implicationsThe study’s findings could motivate practitioners to place more emphasis on leadership support, knowledge sharing and organizational learning in the manufacturing sector.Originality/valueThe study provided diverse paths indicating how transformational leadership can impact organizational learning by examining both the direct and indirect paths between transformational leadership, multiple mediators and organizational learning. It also suggested a research framework for supporting transformational leadership, knowledge sharing and organizational learning, as well as their relationships by examining the three variables in one research model.
Passing and moving: negotiating fieldwork roles in football fandom research
Authors: Richards Jessica 
Published: May 2018

PurposeGaining access to the research field has received much academic attention; however, the literature focusing on the changing and/or multiple roles that researchers adopt during fieldwork has at times been oversimplified. The purpose of this paper is to outline the multiple stages of the fieldwork journey, a more reflexive approach to fieldwork and the research process can be attained.Design/methodology/approachData were generated from a four-year ethnographic study of the match-day experiences of the fans of Everton Football Club. In total, over 100 hours were spent doing fieldwork observations with an additional 25 semi-structured interviews forming the data set.FindingsThis paper argues that researchers should be more critical of their position in the field of their research, and should seek to identify this more clearly in their scholarship. This in turn would enable for more discussions of how each stage of the fieldwork journey affected the scope and overall findings of the research.Originality/valueThis paper provides an alternative framework for ethnographic researchers to better recognise and acknowledge reflexivity throughout the research process. This is done by outlining the various stages of fieldwork engagement more clearly to better understand how researchers change and adapt to the research environment.

Authors: Broos Tom , Verbert Katrien , Langie Greet , Van Soom Carolien , De Laet Tinne 
Published: May 2018

Purpose
The purpose of this paper is to draw attention to the potential of “small data” to complement research in learning analytics (LA) and to share some of the insights learned from this approach.

Design/methodology/approach
This study demonstrates an approach inspired by design science research, making a dashboard available to n=1,905 students in 11 study programs (used by n=887) to learn how it is being used and to gather student feedback.

Findings
Students react positively to the LA dashboard, but usage and feedback differ depending on study success.

Research limitations/implications
More research is needed to explore the expectations of a high-performing student with regards to LA dashboards.

Originality/value
This publication demonstrates how a small data approach to LA contributes to building a better understanding.
On predicting academic performance with process mining in learning analytics
Authors: Umer Rahila , Susnjak Teo , Mathrani Anuradha , Suriadi Suriadi 
Published: May 2018

Purpose
The purpose of this paper is to propose a process mining approach to help in making early predictions to improve students’ learning experience in massive open online courses (MOOCs). It investigates the impact of various machine learning techniques in combination with process mining features to measure effectiveness of these techniques.

Design/methodology/approach
Student’s data (e.g. assessment grades, demographic information) and weekly interaction data based on event logs (e.g. video lecture interaction, solution submission time, time spent weekly) have guided this design. This study evaluates four machine learning classification techniques used in the literature (logistic regression (LR), Naïve Bayes (NB), random forest (RF) and K-nearest neighbor) to monitor weekly progression of students’ performance and to predict their overall performance outcome. Two data sets – one, with traditional features and second, with features obtained from process conformance testing – have been used.

Findings
The results show that techniques used in the study are able to make predictions on the performance of students. Overall accuracy (F1-score, area under curve) of machine learning techniques can be improved by integrating process mining features with standard features. Specifically, the use of LR and NB classifiers outperforms other techniques in a statistical significant way.

Practical implications
Although MOOCs provide a platform for learning in highly scalable and flexible manner, they are prone to early dropout and low completion rate. This study outlines a data-driven approach to improve students’ learning experience and decrease the dropout rate.

Social implications
Early predictions based on individual’s participation can help educators provide support to students who are struggling in the course.

Originality/value
This study outlines the innovative use of process mining techniques in education data mining to help educators gather data-driven insight on student performances in the enrolled courses.
Evaluating influence of technology readiness factors on the Saudi cement companies market and financial based performance
Authors: Alsultanny Yas , AlZuhair Sara 
Published: May 2018

Purpose
The purpose of this paper is to assess the technology readiness factors and their influence on the market- and financial-based performance of Saudi cement companies from managers’ perspective.

Design/methodology/approach
The tool of the study is a questionnaire, which is developed to measure technology readiness from the cement companies’ managers’ perspectives; it has six dimensions with 42 statements.

Findings
The findings showed managers’ degree of agreement on the variables; technology readiness contributors (optimism and innovativeness) were set in the agree category, and the inhibitors (discomfort and insecurity) were set in the neutral category. The results also showed no statistically significant influence from the contributors on market-based performance and moderate influence from the inhibitors on market-based performance.

Research limitations/implications
The research was limited to the Saudi cement companies.

Originality/value
This is the first paper to evaluate the Saudi cement companies for technology readiness from perspective of the companies’ managers.
Transformational leadership influence on unit performance
Authors: Chang Yi-Ying , Chao Wei-Chung , Chang Che-Yuan , Chi Hui-Ru 
Published: May 2018

PurposeThe purpose of this paper is to explore the role of mediation and moderation mechanisms between firm-level effects of transformational leadership (TFL) on unit-level performance across levels.Design/methodology/approachThe authors used surveys to collect data from 800 senior managers at the firm level and 1,377 unit managers from 800 units of 100 firms from semiconductors, optoelectronics, computer electronics, and telecommunications industries. The industries were chosen because these firms focus on expanding their businesses and encourage extensive knowledge sharing among the firms and at all levels within the organizations.FindingsIn this study, the authors theorized that firm-level effects of TFL on unit-level performance across levels were positively related to unit-level performance. Unit-level knowledge sharing mediates the positive relationship between firm-level TFL and unit-level performance. A cross-level interaction effect of firm-level TFL and unit-level absorptive capacity showed that a positive unit-level absorptive capacity enhanced firm-level influence of TFL on unit-level knowledge sharing. Unit-level absorptive capacity moderates the positive relationship between unit-level knowledge sharing and unit-level performance.Originality/valueFirst, the authors attempt to integrate the leadership and knowledge management research by exploring the critical mediator of unit-level knowledge sharing in explaining the effects of firm-level TFL on employees’ performance at the unit level. This approach is important because it extends the research areas of the two fields, and also clarifies issues regarding how and why TFL at the top of the organization positively impacts the performance of employees at a lower level of the organizational hierarchy. Second, the effectiveness of firm-level TFL depends on the absorptive capacity of each unit. The importance of absorptive capacity and the consequences of leadership behaviors have been emphasized in studies.
Unselfish leaders? Understanding the role of altruistic leadership and organizational learning on happiness at work (HAW)
Authors: Salas-Vallina Andres , Alegre Joaquin 
Published: May 2018

Purpose
The purpose of this paper is to examine to what extent altruistic leadership (AL) contribute to happiness at work (HAW). In addition, the authors analyze the mediating role of those conditions that facilitate learning in the relationship between AL and HAW.

Design/methodology/approach
Confirmatory factor analysis by means of structural equation models was performed to check the proposed theoretical model, using a sample of 122 frontline bank employees.

Findings
Results show that, although specific leadership styles might contribute to employee well-being, it seems the shared characteristic of altruism what significantly impact employees HAW, by means of organizational learning capability.

Originality/value
Scarce research examines altruism as a leadership behavior. The authors provide to the leadership literature a theoretical model, and empirical evidence that altruism is an essential leadership behavior to promote learning and HAW.
Revisiting the fairness paradigm in India
Authors: Rehman Varisha 
Published: May 2018

Purpose
The paper answers three research questions: How does the extant literature explain fairness and whiteness? What Indian standards of beauty were historically, and how are they currently? What is the applicability of the theory of self-concept in understanding the fairness paradigm?

Design/methodology/approach
A rigorous review of extant literature on fairness followed by consolidation of the literature under relevant self-concept theory for understanding the historical perspective of fairness in India as compared to global standards.

Findings
Clear defined themes on actual, ideal and social self-concept emerged from the study. The study also revealed: how Indian corporates are using effective marketing strategies to cover up the potential health hazards of fairness creams.

Practical implications
Marketers can use the study to understand how fairness products influence individual’s self-concept. Media houses and Government agencies can also get insight on how beauty has been valorized in the Indian mindset.

Social implications
This paper identifies the deceptive and misrepresentation of attainable beauty standards claimed by the fairness and whiteness products.

Originality/value
This is the first study done to integrate the findings of fairness studies with self-concept theory and derive useful insights from it.
The genome of an endosymbiotic methanogen is very similar to those of its free‐living relatives
Authors: Beinart R.A. , Rotterová J. , Čepička I. , Gast R.J. , Edgcomb V.P. 
Published: May 2018

SummaryThe methanogenic endosymbionts of anaerobic protists represent the only known intracellular archaea, yet, almost nothing is known about genome structure and content in these lineages. Here, an almost complete genome of an intracellular Methanobacterium species was assembled from a metagenome derived from its host ciliate, a Heterometopus species. Phylogenomic analysis showed that the endosymbiont was closely related to free‐living Methanobacterium isolates, and when compared with the genomes of free‐living Methanobacterium, the endosymbiont did not show significant reduction in genome size or GC content. Additionally, the Methanobacterium endosymbiont genome shared the majority of its genes with its closest relative, though it did also contain unique genes possibly involved in interactions with the host via membrane‐associated proteins, the removal of toxic by‐products from host metabolism and the production of small signalling molecules. Though anaerobic ciliates have been shown to transmit their endosymbionts to daughter cells during division, the results presented here could suggest that the endosymbiotic Methanobacterium did not experience significant genetic isolation or drift and/or that this lineage was only recently acquired. Altogether, comparative genomic analysis identified genes potentially involved in the establishment and maintenance of the symbiosis, as well provided insight into the genomic consequences for an intracellular archaeum.
Comparative Efficiency of Family and Corporate Farms: Does Family Labour Matter?
Authors: Kostov Philip , Davidova Sophia , Bailey Alastair 
Published: May 2018

AbstractWe examine the comparative efficiency of family relative to corporate farms, usingFADNdata for the Czech Republic, Hungary, Romania and Spain. We estimate a non‐parametric non‐separable farm production function, and derive efficiency scores for both family and corporate farms. We decompose efficiency into two distinct sources – organisational differences and management capabilities. We find evidence for organisational efficiency gains from family farming, relative to corporate farming, and these appear to increase with family involvement. However, with regard to management capabilities, family farms do not compare so favourably. Furthermore, family involvement does not seem to have any systematic effect on the efficiency derived from management capabilities. Our findings suggest that further investigation of the way family farms employ and build management capabilities is needed to substantiate any ‘superiority’ claims.
The Impact of Dividend Reinvestment Plans on Firm Payout Choices—Evidence from Real Estate Investment Trusts
Authors: Bond Shaun A. , Pai Yu‐Jou , Wang Peng , Zheng Suyan 
Published: May 2018

AbstractThis study investigates whether firm dividend payout choices are influenced by the presence of a Dividend Reinvestment Plan (DRIP). Given that DRIPs help retain capital, we show that dividend‐paying firms with a DRIP will tend to pay a high dividend and maintain a stable payout policy. Using a multinomial logistic model, we show that in comparison to REITs without DRIPs, REITs with DRIPs have a higher payout ratio and are less likely to: (1) pay regular dividends with extra dividends and share repurchases, (2) distribute extra dividends, repurchase shares, yet omit regular dividends and (3) omit all payouts. In addition, we find that REITs with a capital‐retaining DRIP invest more aggressively and such increased investment activities are undertaken without raising the reliance on external financing.
The impact of growth rate and environmental factors on mutation rates and spectra in Escherichia coli
Authors: Maharjan Ram P. , Ferenci Thomas 
Published: May 2018

SummaryGenetic variation in bacterial populations is remarkably sensitive to environmental influences, including simple, nutritional differences. Not only the rate but also the kind of mutational changes is biased by the nutritional state of bacteria. Here we investigate the mutational consequences of a universal variable for free‐living bacteria, namely the growth rate. By controlling growth in chemostats, the rate and mix of mutations was investigated for populations of Escherichia coli subject to different specific growth rates. Both aerobic and anaerobic cultures were compared with see if growth rate is a factor in the commonest respiratory conditions for E. coli. We find mutation rates are raised markedly with decreasing growth rate. Base pair substitutions and 1‐bp insertions and deletions increase with reduced growth rate, but less so in anaerobic cultures. Insertion sequence movements are particularly sensitive to growth rate, with IS2 being optimal at intermediate growth rates whereas IS1 and IS150 movements are highest at the slowest tested growth rate. A comprehensive comparison of growth rate effects, as well as six other environmental factors, provides the most complete picture yet of the range of mutational signatures in bacterial genetic variation.
The relationship between operating leverage and financial leverage
Authors: Sarkar Sudipto 
Published: May 2018

AbstractWe model the relationship between operating and financial leverage. When operating leverage is exogenously specified, financial leverage is a monotonically decreasing function of operating leverage. When financial leverage is exogenously specified, operating leverage is initially increasing and subsequently decreasing in financial leverage. Finally, when both operating and financial leverage are chosen by the firm, they can be positively related, negatively related or unrelated, depending on which underlying parameter is driving the changes. Thus, operating leverage and financial leverage do not always behave as substitutes, as argued in the traditional literature. The relationship is complex, possibly non‐monotonic and dependent on the circumstances; empirical tests need to take this reality into account.
Work settings of the first seven cohorts of James Cook University Bachelor of Medicine, Bachelor of Surgery graduates: Meeting a social accountability mandate through contribution to the public sector and Indigenous health services
Authors: Woolley Torres , Sen Gupta Tarun , Larkins Sarah 
Published: May 2018

AbstractObjectiveThe James Cook University medical school's mission is to produce a workforce appropriate for the health needs of northern Australia.Design, setting and participantsJames Cook University medical graduate data were obtained via cross‐sectional survey of 180 early‐career James Cook University medical graduates from 2005–2011 (response rate of 180/298 contactable graduates = 60%). Australian medical practitioner data for 2005–2009 graduates were obtained via the 2015 ‘Medicine in Australia: Balancing Employment and Life’ wave 8 dataset.Main outcome measureComparison of the range of work settings and hours worked by James Cook University medical graduates to Australian medical graduates.ResultsCompared to a similar group of Australian medical graduates, James Cook University Bachelor of Medicine, Bachelor of Surgery graduates are significantly more likely to work in government‐funded ‘public’ organisations (hospitals, community health centres, Aboriginal Community Controlled Health Services, government departments, agencies or defence forces). In particular, James Cook University medical graduates were more likely to work in Aboriginal Community Controlled Health Services and community health centres and other state‐run primary health care organisations than other Australian medical graduates.ConclusionJames Cook University medical graduates appear to work in a higher proportion of public settings; in particular, primary care settings, than Australian medical graduates. This is an appropriate mix for the predominantly rural and remote geography of Queensland and its associated medical workforce priorities. Reporting medical graduate outcomes by their nature of practice could be an important adjunct to other measures, such as geographic location and choice of specialty.
Progression to total hip arthroplasty following hip arthroscopy
Authors: McCarthy Brendon , Ackerman Ilana N. , de Steiger Richard 
Published: May 2018

BackgroundHip arthroscopy is a minimally invasive surgical technique increasingly being used to treat hip pathology. There is evidence that a proportion of patients require total hip arthroplasty in the years immediately following arthroscopy, suggesting that these patients have derived only a limited benefit from the procedure. Identification of risk factors for early progression to hip arthroplasty may enable refinement of hip arthroscopy indications and more informed decision making. The aim of this study is to identify the proportion of patients in a hip arthroscopy cohort who progress to total hip arthroplasty within 2 years of arthroscopy, and to analyse risk factors for this early progression.MethodsA retrospective cohort analysis was conducted on all patients who underwent hip arthroscopy at one tertiary institution from 2004 to 2013. Hospital data were linked to the Australian Orthopaedic Association National Joint Replacement Registry in 2016 to identify subsequent hip arthroplasty.ResultsThere were 989 arthroscopies performed on 947 patients; 447 were female (48.1%), the mean age was 41.1 years (SD: 14.23) and osteoarthritis was present at arthroscopy in 31.5%. Total hip arthroplasty occurred in 129 patients (13%) within 2 years. Multivariable logistic regression revealed osteoarthritis, age >50 years and previous arthroscopy were significant risk factors for arthroplasty within 2 years (adjusted odds ratios (confidence intervals): 4.6 (2.91–7.16), 3.8 (2.44–5.87), 2.5 (1.16–5.81)).ConclusionsOsteoarthritis, older age and history of arthroscopy were independent risk factors for early progression to arthroplasty; these factors should be considered within clinical decision‐making, and when discussing potential arthroscopy outcomes with patients.
