Potential of gear-ring turbulator in three-dimensional heat exchanger tube from second law of thermodynamic viewpoint
Authors: Moghaddaszadeh Navid , Rashidi Saman , Abolfazli Esfahani Javad 
Published: December 2018

Purpose
This paper aims to use the second law of thermodynamic to evaluate the potential of gear-ring turbulator in a three-dimensional heat exchanger tube. Accordingly, a numerical simulation is performed to obtain the irreversibilities in a three-dimensional heat exchanger tube equipped with some gear-ring turbulators for turbulence regime.

Design/methodology/approach
A numerical simulation is performed to obtain the irreversibilities in a three-dimensional heat exchanger tube equipped with some gear-ring turbulators for turbulence regime. The analysis is carried out based on shear stress transport (SST) k-ω turbulent model. The influences of different parameters containing tooth number, free-space length ratios and Reynolds number on frictional and thermal irreversibilities and Bejan number are discussed.

Findings
The results indicated that the thermal irreversibility reduces by decreasing the tooth number. For example, the thermal entropy generation decreases about 25.81 per cent by decreasing the tooth number in the range of 24 to 0 at Re = 6,000. Moreover, the frictional entropy generation decreases by increasing the tooth number as the gear with more tooth number causes a lower flow disturbance.

Originality/value
The present study arranged a numerical work to study the potential of a gear-ring turbulator in a heat exchanger tube from first and second laws of thermodynamic viewpoint. The turbulent flow is considered for this problem. The literature review showed that the usage of a gear-ring turbulator in a heat exchanger tube is not investigated from the second law of thermodynamic viewpoint by previous studies. As a result, the influences of different parameters containing tooth number, free-space length ratios and Reynolds number on frictional and thermal irreversibilities and Bejan number are discussed.

Authors: Ambarkhane Dilip , Singh Ardhendu Shekhar , Venkataramani Bhama 
Published: December 2018

PurposeMicrofinance institutions (MFIs) provide small loans and other financial services to the poor. These institutions are established for helping the poor to raise income levels and to reduce poverty. Recently, MFIs are required to reduce their dependence on grants and subsidies. Consequently, they face conflicting objectives of improving reach and profitability. These can be achieved by improving productivity. This paper aims to investigate productivity change in 21 major MFIs in India which are rated by Credit Rating and Information Services of India Limited in 2014.Design/methodology/approachThis paper attempts to examine total factor productivity change in 21 major Indian MFIs during the period from 2014 to 2016 using Malmquist productivity index. The inputs and outputs are selected considering objectives of outreach and financial sustainability. The authors have categorized MFIs in three categories, namely, large, medium and small, depending on asset size.FindingsIt is revealed that large MFIs are able to catch up with industry best practices by improving their systems and processes, but they need to improve scale efficiency. The Reserve Bank of India has recently initiated a policy of granting banking licenses to those financial institutions which have good outreach and are financially strong. It can be used for shortlisting MFIs before granting permission to operate as banks. The method can also be used for benchmarking them for productivity. It can also be replicated in other countries.Originality/valueIn India, MFIs are playing important role in economic development by providing microcredit to the poor. However, very few studies have been undertaken regarding productivity of MFIs in India. The present study intends to fill this gap. It will facilitate benchmarking of MFIs as competitive and sustainable financial institutions catering to the requirements of small borrowers.
Organisational factors: impacting on health for ambulance personnel
Authors: Harrison Juliet 
Published: December 2018

Purpose
The purpose of this paper is to establish if organisational factors are leading to a negative effect on ambulance personnel’s health. In recent years, frontline ambulance personnel have displayed a consistent high rate of sickness amongst healthcare workers within the National Health Service in the UK. Post-traumatic stress disorder (PTSD) has previously been cited, but organisational factors may be stressors to health.

Design/methodology/approach
A search of electronic databases MEDLINE EBSCO, MEDLINE OVID, MEDLINE PUBMED, AMED, CINAHL, Web of Science, Zetoc within the time period of 2000–2017 resulted in six mixed methods studies. Hand searching elicited one further study. The literature provided data on organisational and occupational stressors (excluding PTSD) relating to the health of 2,840 frontline ambulance workers in the UK, Australia, Norway, the Netherlands and Canada. The robust quantitative data were obtained from validated questionnaires using statistical analysis, whilst the mixed quality qualitative data elicited similar themes. Narrative synthesis was used to draw theories from the data.

Findings
Organisational factors such as low job autonomy, a lack of supervisor support and poor leadership are impacting on the health and well-being of frontline ambulance workers. This is intertwined with the occupational factors of daily operational demands, fatigue and enforced overtime, so organisational changes may have a wider impact on daily occupational issues.

Originality/value
The findings have possible implications for re-structuring organisational policies within the ambulance service to reduce staff sickness.

Authors: Mishra Mrigendra Nath 
Published: December 2018

PurposeThe purpose of this paper is analysis of Green and Lean Six Sigma, based on the success factors in its use through a well thought-out literature review, is being planned; a framework has been integrated in a productive manner with the Green and Lean and Six Sigma methods so as to incorporate and actualize the execution.Design/methodology/approachThe methodology consists of comparative investigation of Green, Lean management and Six Sigma using open written work, essential analysis at data and master experience of the researchers. To achieve this goal, a significant review of the existing literature of the subject area has been done to prepare a framework in view of the critical success factors. A study was arranged and flowed survey from various businesses utilizing John’s Macintosh Project (JMP) statistical software.FindingsThe paper establishes the distinguishing proof of five success factors with their situational importance and shows that the integrated Green and Lean Six Sigma can drive the organizations to optimize their resources and cost of services or productions.Practical implicationsA Green and Lean Six Sigma organization would take profits by the use of the proposed framework in an alternate extent of organizations should be dynamic. The organizations should assess their shortcomings and qualities, set needs and perceive objectives for fruitful implementation.Originality/valueSuggestions are being made regarding thoughts and methods that would constitute a Green and Lean Six Sigma organization. The suggested framework compare the method for improvements that may occur in organizations while implementation of the Green and Lean management or Six Sigma.
“I don’t complain, but I am ready for any eventuality”
Authors: Paillé Pascal , Valéau Patrick 
Published: December 2018

PurposeThe purpose of this paper is to investigate the extent to which the influence of professional commitment on intention to leave a profession is contingent on the combined effect of job search and sportsmanship.Design/methodology/approachThe research is based on a sample of professional employees (N= 327). Moderated moderation was the approach used for testing the hypotheses.FindingsFindings showed that the moderating effect of job search on the relationship between professional commitment and intention to leave a profession is higher at a low level of sportsmanship and lower when sportsmanship is high.Originality/valueThe research indicates that job search does not necessarily constitute a sign of acceleration of intention to leave one’s profession. In the case of professionals expressing a high level of sportsmanship, job search appears more like a precaution.
New CEOs’ previous experience and acquisition performance
Authors: Woo Heejin 
Published: December 2018

PurposeThis study aims to investigate how new CEOs’ previous experiences in other organizations and other industries create value in acquisitions. Drawing on the upper echelon perspective, this study theorizes that the multiorganizational experience of new CEOs is positively associated with acquisition performance and, in particular, that the multi-industry experience of new CEOs leads to better performance in diversifying acquisitions than in related acquisitions. While new CEOs without multiorganizational experience undergo a cognitive entrenchment in firm-specific experience, new CEOs with multiorganizational experience can lead acquisitions with more flexibility and agility.Design/methodology/approachAcquisition and organizational data were drawn from the US manufacturing industries (SIC 20-39) between 2008 and 2010. The event study method was used to test hypotheses. In 346 acquisitions made by 139 firms, acquisition performance was measured according to cumulative abnormal returns.FindingsConsistent with the hypotheses, the multiorganizational experience of new CEOs was positively associated with acquisition performance and, in particular, the multi-industry experience of new CEOs led to better performance in diversifying acquisitions than in related acquisitions.Originality/valueThis paper contributes to the CEO literature and acquisition literature by suggesting that the multiorganizational experience of new CEOs can be a valuable source of competitive advantages, particularly when implementing corporate strategies involving interorganizational integration processes.
Public-private partnerships in developing countries
Authors: Kang Seong , Mulaphong Dhanakorn , Hwang Eunjin , Chang Chih-Kai 
Published: December 2018

Purpose
Mounting fiscal constraints and increasing complexity of public services have led governments to search for alternative service delivery mechanisms. The public–private partnership (PPP) is one type of service arrangement in which the public and private sectors enter into a long-term cooperative relationship for the purpose of delivering a public good or service. Despite increasing private sector participation in developing nations, there is a need for more systematic assessment of PPPs in such countries. The purpose of this paper is to explore the factors that affect the adoption and implementation of projects in the context of developing countries.

Design/methodology/approach
A multiple case holistic design is employed to analyze 19 select projects across several developing countries to identify and pool clusters of variables that facilitate or impede PPPs.

Findings
The results indicate five broad categories of political, economic, legislative, financial and management requisites.

Research limitations/implications
A limitation of this research is that the cases were not selected at random. However, the projects are spread across several areas such as public health, public utilities, public works, transportation and water/wastewater infrastructure in different countries. This allows the authors to examine how the common factors apply across different contextual settings.

Originality/value
This paper seeks to contribute to the literature by examining several developing countries to identify and pool clusters of variables that facilitate or impede the effective implementation of PPP projects in the context of such regions.
Another look at motivating – and retaining – salespeople
Authors: Lai Christine Jaushyuam , Gelb Betsy D. 
Published: December 2018

Purpose
This study aims to investigate to what extent salespeople are satisfied, dissatisfied or neither with various aspects of their job in ways predicted by the “two-factor model” assocating satisfaction with recognition and personal growth but not “hygiene factors.” It further investigates which aspects of the salesperson’s job are most strongly associated with commitment to the organization – or intention to leave.

Design/methodology/approach
Interviewers gathered data from 176 salespeople in 154 companies. Those data were analyzed to identify aspects of the salesperson’s job that are satisfiers, dissatisfiers or prompt indifference. The data were then correlated with the extent to which salespeople expressed commitment to their organization – and the extent to which they expressed likelihood of leaving their current job.

Findings
Aspects of the salesperson’s job do cluster into categories associated with the two-factor theory: satisfiers, dissatisfiers and other “hygiene factors” that are neither. However, two deviations from the theory appear. Pay is a satisfier, contrary to the assumptions behind the model, and factors beyond those intrinsic to the salesperson are also satisfiers. Supporting relevance of the theory for salespeople, however, is the strong association of recognition/personal growth aspects of the job positively with organizational commitment and negatively with intention to leave.

Research limitations/implications
Although the data come from a convenience sample of salespeople, the results can be useful. For example, consideration of new products and of mergers should take into account their impact on salesperson satisfaction and dissatisfaction as motivational issues.

Originality/value
This study is broader in focus than previous work relating the two-factor theory to salespeople, providing more confidence in the generalizability of the results.
Reshaping mental models – enabling innovation through service design
Authors: Vink Josina , Edvardsson Bo , Wetter-Edman Katarina , Tronvoll Bård 
Published: December 2018

Purpose
The purpose of this paper is to analyze how service design practices reshape mental models to enable innovation. Mental models are actors’ assumptions and beliefs that guide their behavior and interpretation of their environment.

Design/methodology/approach
This paper offers a conceptual framework for innovation in service ecosystems through service design that connects the macro view of innovation as changing institutional arrangements with the micro view of innovation as reshaping actors’ mental models. Furthermore, through an 18-month ethnographic study of service design practices in the context of healthcare, how service design practices reshape mental models to enable innovation is investigated.

Findings
This research highlights that service design reshapes mental models through the practices of sensing surprise, perceiving multiples and embodying alternatives. This paper delineates the enabling conditions for these practices to occur, such as coaching, diverse participation and supportive physical materials.

Research limitations/implications
This study brings forward the underappreciated role of actors’ mental models in innovation. It highlights that innovation in service ecosystems is not simply about actors making changes to their external context but also actors shifting their own assumptions and beliefs.

Practical implications
This paper offers insights for service managers and service designers interested in supporting innovation on how to catalyze shifts in actors’ mental models by creating the conditions for specific service design practices.

Originality/value
This paper is the first to shed light on the central role of actors’ mental models in innovation and identify the service design practices that reshape mental models.
Collaboration with private companies as a vehicle for school improvement
Authors: Sahlin Susanne 
Published: December 2018

Purpose
The purpose of this paper is to examine principals’ experience and sensemaking of collaboration with private companies, focussing on leadership and school improvement.

Design/methodology/approach
This paper is set against the backdrop of a project where three public Swedish schools collaborated with private companies within their communities. Data were collected over three years and consisted of semi-structured interviews, meeting notes, field observations, field notes and document analysis. A qualitative content analysis was performed using the Atlas.ti 6.2 software tool.

Findings
The study shows that important sensemaking for the principals in this collaboration between schools and private companies is related to the sense of collective responsibility and involvement, development of improvement culture and trust between key actors, and common improvement initiatives based on mutual interest. Challenges in the collaboration are related to principal changes, a lack of implementation of the collaboration, and that there was no clear vision of external collaboration in two out of three schools. In terms of possibilities, the collaboration was based on the needs of the school, a collaborative culture was developed, and the development/activities were undertaken between involved schools and private companies during the collaboration.

Research limitations/implications
Inevitably, there are limitations that need to be identified and recognised in this study. First, the small number of cases in this multiple case study, as well as the specific social context, limits the possibility of generalising the findings. Second, the study was not independently selected, and the findings and analyses are linked to national and local contexts, which can be seen as a limitation and strength. Notwithstanding, this study contributes with in-depth information about how a beyond-school collaboration with private companies is practised as well as how involved principals made sense of the collaboration from the perspective of school improvement.

Originality/value
The originality is the collaboration between schools and private companies. The paper contributes with new knowledge about how principals experience and make sense of this collaboration as a vehicle for school improvement.
Hoteliers as crime control partners
Authors: Morton Paul J. , Luengen Kelsy , Mazerolle Lorraine 
Published: December 2018

Purpose
The purpose of this paper is to present evaluation results of Operation Galley, an intelligence-led policing (ILP) intervention that sought to proactively address the problem of drug dealing from hotel rooms by engaging hoteliers as crime control partners with the Queensland Police Service.

Design/methodology/approach
Operation Galley, a randomized control field trial, rank ordered and matched 120 hotels on size, star rating, location and estimated degree of suspicious behaviour. Hotels were randomly assigned to one of three conditions: Operation Galley hotels who received a procedurally just letter, followed by a personal visit with detectives; the letter-only hotels who received the procedurally just letter; and the business as usual hotels.

Findings
Using repeated measures ANOVA and general linear models, results of the 12-month trial indicate that the Operation Galley condition led to an increase in police engagement with hoteliers, increasing the recognition, reporting and police enforcement of drug offenders.

Practical implications
The Operation Galley trial demonstrates that the ILP approach helped foster positive engagement between hoteliers and detectives. The approach cultivated hoteliers as crime control partners and thereby increased the flow of human source intelligence, helping police to better target and respond to drug dealing problems in hotel rooms.

Originality/value
Results of the Operation Galley trial demonstrate that hoteliers can be leveraged as crime control partners, providing important human source intelligence about drug dealing and facilitating the capacity of police to better respond to drug problems in hotels.
Exploring the relationship between corporate responsibility and firm performance from a social media perspective
Authors: Cao Ray Qing , Schniederjans Dara G. , Gu Vicky Ching , Schniederjans Marc J. 
Published: December 2018

PurposeCorporate responsibility perceptions from stakeholders are becoming more difficult to manage. This is in part because of large amount of social media being projected to stakeholders on a daily basis. In light of this, the purpose of this paper is to examine the relationship between corporate responsibility framing from the social media perspective firm’s performance as defined by abnormal-return (defined as the difference between a single stock or portfolios return and the expected return) and idiosyncratic-risk (defined as the risk of a particular investment because of firm-specific characteristics).Design/methodology/approachHypotheses are developed through agenda-setting theory and stakeholder and shareholder viewpoints. The research model is tested using sentiment analysis from a collection of social media from several industries.FindingsThe results provide support that three corporate responsibility social media categories (economic, social and environmental-framing) will have different impacts (delayed, immediate) on abnormal-return and idiosyncratic-risk. This study finds differences between immediate (one-day lag) and delayed (three-day lag) associations on abnormal-return and idiosyncratic-risk.Originality/valueThis study also suggests differences between the amount and sentiment of corporate responsibility social media framing on abnormal-return and idiosyncratic-risk. Finally, results identify interaction effects between different corporate responsibility social media categories.
Regenerating the learning organisation: towards an alternative paradigm
Authors: Pedler Mike , Hsu Shih-wei 
Published: December 2018

PurposeThis paper aims to take a critical view of the concepts of the Learning Organisation and Organisational Learning (LO/OL) and respond to two questions about their current state: are existing perspectives on LO/OL still fit for purpose? What are the possibilities for an alternative paradigm of LO/OL?Design/methodology/approachThe paper critically reviews the literature of LO/OL and uses the concept of problematisation together with some guiding principles from ancient wisdoms to articulate an alternative paradigm.FindingsTwo waves of LO/OL are identified. A first wave rests on a series of assumptions that have shaped a predominant understanding of LO/OL, including the suppositions that all learning is good; that those organisations adopting LO/OL strategies are engaged in useful work and in pursuing socially valuable ends; and that neo-liberal beliefs favouring market-based solutions are the most appropriate response to organisational problems. A more reflexive approach to LO/OL has challenged these predominant views, and although it has had little impact on practice, it paves the way for a possible second wave perspective. With the help of a theoretical excursion of Taoism and Buddhism, the authors portray a possible picture of a new paradigm for LO/OL.Originality/valueWhilst existing critical accounts have problematised the mainstream assumptions of LO/OL, they have not clearly indicated any different perspectives. Drawing upon ancient wisdom, the paper identifies some guiding principles for an alternative LO/OL paradigm and discourse.
