Linear stability analysis of finite hydrodynamic journal bearing under turbulent lubrication with coupled-stress fluid
Authors: Ghosh Abhishek , Kumar Guha Sisir 
Published: January 2017

Purpose
Several researchers have observed that to satisfy modern day’s need, it is essential to enhance the characteristics of journal bearing, which is used in numerous applications. Moreover, the use of Newtonian fluid as a lubricant is diminishing day by day, and the use of Non-Newtonian fluids is coming more into picture. Furthermore, if turbo-machinery applications are taken into account, then it can be seen that journal bearings are used for high speed applications as well. Thus, neglecting turbulent conditions may lead to erroneous results. Hence, this paper aims to present focuses on studying the stability characteristics of finite hydrodynamic journal bearing under turbulent coupled-stress lubrication.

Design/methodology/approach
First, the governing equation relevant to the problem is generated. Then, the dynamic analysis is carried out by linear perturbation technique, leading to three perturbed equations, which are again discretized by finite difference method. Finally, these discretized equations are solved with the help of Gauss-Seidel Iteration technique with successive over relaxation scheme. Consequently, the film response coefficients and the stability parameters are evaluated at different parametric conditions.

Findings
It has been concluded from the study that with increase in value of the coupled-stress parameter, the stability of the journal may increase. Whereas, with increase in Reynolds number, the stability of the journal decreases. On the other hand, stability increases with increasing values of slenderness ratio.

Originality/value
Researches have been performed to study the dynamic characteristics of journal bearing with non-Newtonian fluid as the lubricant. But in the class of non-Newtonian lubricants, the use of coupled-stress fluid has not yet been properly investigated. So, an attempt has been made to perform the stability analysis of bearings with coupled-stress fluid as the advanced lubricant.

Authors: Potluri Rajasekhara Mouly , Ansari Rizwana , Khan Saqib Rasool , Dasaraju Srinivasa Rao 
Published: January 2017

Purpose
This study aims to investigate the attitude and consciousness of Indian Muslims toward halal and also to indicate the alertness of Muslim students about halal in their daily life.

Design/methodology/approach
A total of 500 respondents were selected for the study from the State of Andhra Pradesh in India, by stratified random sampling method; of which 300 were general Muslims and 200 were Muslim students. Self-administrated questionnaire and personal interviews were administered to garner the data, which were analyzed with SPSS (version 21.0) and GRETL, and the research hypotheses were tested with Z-test for proportion and Pearson’s chi-square test.

Findings
A total of 92 and 98 per cent of respondents from the general Muslim community and Muslim students, respectively, agreed that they do not have proper exposure to halal. In addition, 89 per cent of general Muslims believe that the halal concept is very significant to Muslim consumers as against 95 per cent students. A total of 98 and 96 per cent of the selected two classes of respondents, respectively, are intended to know more about halal.

Research limitations/implications
The respondents in this research were general Muslims and Muslim students from Andhra Pradesh. The results of this research are, therefore, only applicable to the sampled community. Hence, generalization of the findings to the whole Indian Muslim population or to other areas of Muslim communities should be avoided.

Practical implications
This research results proffer most precious and ingenious information to the corporate sector, Islamic religious organizations and educational institutions specially involved in formal Islamic education. Based on the snowballing trend of Muslim population from the present 250 million to the whopping 340 million by the end of this century, it is an inspired decision to target this lucrative segment which provide alluring profitability particularly food, cosmetics, medicines, etc., with Halal certified products. Specially, Islamic religious organizations also have an enormous onus to enhance the ken of this community on the matters comprehensively germane to Islam in general and about halal and haram in particular.

Originality/value
This is the first ingenious effort aimed to investigate the attitude and awareness toward halal among general Muslims and Muslim students. This is a pioneering attempt on halal of Indian Muslims which is lucrative for both corporate sector and to the academia.
Halal logistics opportunities and challenges
Authors: Zailani Suhaiza , Iranmanesh Mohammad , Aziz Azmin Azliza , Kanapathy Kanagi 
Published: January 2017

Purpose
The purpose of the paper is to investigate the challenges and opportunities for logistics companies in Malaysia to adopt halal logistics. Logistics plays a key role in protecting the halal integrity of halal food through proper transportation, storage and handling along the supply chain until it reaches its final destination.

Design/methodology/approach
This research builds on existing research published in the Journal of Islamic Marketing on halal logistics. In addition to an extensive literature review, five focus group discussions were conducted to discover the challenges and opportunities with regards to halal logistics services in Malaysia.

Findings
The results show that the future market demands and the competitive opportunities related to halal services are the main motivators of first movers in halal logistics. The early adopters of halal logistics face several challenges such as ambiguous halal guidelines, lack of international halal certification, lack of collaboration among governing agencies (i.e. logistics service providers (LSPs), Jabatan Kemajuan Islam Malaysia (JAKIM) and Halal Industry Development Corporation), a lack of cost-effective standards, an overly competitive transportation sector, lack of demand, lack of halal logistics compulsion, financial challenges and a general misunderstanding of halal practices.

Practical implications
The findings of the present study may help government policy makers recognise the issues that should be addressed in motivating logistics companies to adopt halal practices.

Originality/value
Although halal logistics plays a key role in protecting the halal integrity of halal products, there are few halal LSPs. This study contributes to the advancement of knowledge on the challenges and opportunities of adopting halal logistics.
Social business model design and implementation in developing countries
Authors: Sabatier Valerie , Medah Ignace , Augsdorfer Peter , Maduekwe Anthony 
Published: January 2017

Purpose
The purpose of this paper is to contribute to the emergent research on social business models by revealing challenges encountered by the design and implementation of such business models.

Design/methodology/approach
Case study of the development of FACA, an affordable medicine used to treat sickle cell disease, from traditional medicine to market in Burkina Faso.

Findings
Social business models present important challenges in terms of value capture for all stakeholders. The social profit equation and the profit equation suggested by Yunus et al. are difficult to apply in practice, and therefore, social business model design should consider the social and profit equations jointly.

Originality/value
Developing countries are seeking different approaches to innovation and healthcare. Social business models appear as one of the potential solutions to bring value to society, organizations, and individuals. The identification of challenges raised by social business models can help policymakers and executives in the design and implementation of these social business models.
Emissions from international transport in global supply chains
Authors: Gurtu Amulya , Searcy Cory , Jaber M.Y. 
Published: January 2017

Purpose
This paper aims to highlight the importance and need to include carbon emissions from international transport in the sourcing decisions of corporate organizations and the calculation of national emissions inventories (NEIs).

Design/methodology/approach
The paper proposes a method of attributing emissions from international transportation in global supply chains and calculating their impact on the economic sustainability of corporate organizations through a carbon price.

Findings
An application of the original model developed in this paper showed that international transport emissions can have an important effect on NEIs. An example of the imports of manufactured items from China and Germany to the USA showed a 3 per cent increase in emissions from manufacturing activities in the USA.

Research limitations/implications
Introducing carbon pricing on international transport emissions is expected to motivate corporate leaders to include emissions from international transport as a factor in their sourcing decisions.

Practical implications
Inclusion of international transport emissions along with the imposition of a carbon tax are designed to act as disincentives to generating emissions from supply chain activities. It is argued that the implementation of the model may provide long-term benefits associated with reduced emissions and a level playing field to organizations which use efficient technologies in manufacturing.

Social implications
It is recognized that the implementation of a carbon tax on international transport emissions may face resistance from several stakeholders, including governments of exporting countries, corporations and customers, due to an increase in cost.

Originality/value
This paper provides an original method to include emissions from international transport in supply chain decisions.
Management as a science-based profession: a grand societal challenge
Authors: Romme Georges 
Published: January 2017

Purpose
The purpose of this paper is to explore how the quest for management as a science-based profession, conceived as a grand societal challenge, can be revitalized.

Design/methodology/approach
A reflective approach is adopted by questioning some of the key assumptions made by management scholars, especially those that undermine their capacity to inform management practice. One key assumption is that management needs to be done by a few people at the top of the organization; this idea is widespread but false.

Findings
An important finding is that the future of the management discipline may largely depend on the rise of new forms of management drawing on distributed intelligence and circularity of power and authority. Management scholars thus need to shift their attention from an almost exclusive focus on managerial intentions and behaviors to (the development and use of new) management technologies, similar to how modern aviation technology involves airplanes that only to a limited extent require intervention and control by a single pilot.

Practical implications
The practical implications of the shift from managerial behavior to management technology are illustrated by means of so-called circular management practices, also known as holacracy and sociocracy.

Originality/value
This paper provides a novel perspective on how the quest for science-based professionalism in management, as a grand societal challenge, can be revitalized.
Call for articles: education at a tipping point scenarios and narratives
Authors: Abeles Tom P. 
Published: January 2017

Purpose
Education from PreK to Grey, internationally, has reached a tipping point. Although the area has a vast literature outlining the issues at hand, there is no consistent vision on how to get beyond the criticism and to propose a clear path forward, particularly in a global, interconnected world.

Design/methodology/approach
On the Horizon, a foresight academic journal, with a strong focus on education is committing the quarterly issues to encourage critical analysis and define paths to addressing the issues at hand. It is seeking: research supported, analysis, scenarios and other futures tools for visioning, and the use of multi-media vehicles for experiencing and demonstrating opportunities, including games/simulations, interactive vehicles and “maker” options.

Findings
The foresight literature offers a rich set of methodologies for exploring potential futures, weighing the effects and providing strategic options. Yet, few of these have been critically applied to the PreK to Grey arena of education, particularly in a globally connected society with new entrants to the field and the increasing capabilities of artificial intelligence.

Originality/value
The study in this issue/volume of On the Horizon provides a platform to focus educational change and resituate it in the larger international societal frame.

Leading under pressure: evaluating the decision-making style of NHL coaches
Authors: Trottier Kim 
Published: January 2017

Purpose
The purpose of this paper is to establish the optimal decision-making style in a fast-paced, complex, and dynamic environment.

Design/methodology/approach
Three decision-making attributes are explored: the use of intuition vs analysis, the proclivity to heuristics, and susceptibility to bias. The intuition/analysis is tested with a questionnaire that has been validated in prior research, while information on the two other dimensions is from an exploratory survey designed for this purpose. Responses to the survey questions provide some insight into the differential decision-making style of elite NHL hockey coaches’ vis-à-vis amateur coaches and news reporters.

Findings
The data suggest elite decision makers have no preference for intuitive or analytical settings, but exhibit a significantly higher perception of their ability to perform in both. While current literature shows sports athletes to be more intuitive, it appears coaches excel on the analytical dimension instead. This study finds that while elite hockey coaches have fewer biases overall, they tend in particular to be overly optimistic in comparison to amateur coaches and news reporters.

Research limitations/implications
The main limitation in this paper is that the survey on heuristics and biases is exploratory, making these results less robust than the findings on intuition and analysis.

Originality/value
This paper is first to extend the decision-making literature to coaches, and among few papers that obtain insights from NHL coaches directly. The findings are likely to extend to corporate leadership as well, increasing the relevance of the results.
Compaction trend versus seismic anisotropy in shaly formations
Authors: Pervukhina Marina , Rasolofosaon Patrick N.J. 
Published: January 2017

ABSTRACTShales comprise more than 60% of sedimentary rocks and form natural seals above hydrocarbon reservoirs. Their sealing capacity is also used for storage of nuclear wastes. The world's most important conventional oil and gas reservoirs have their corresponding source rocks in shale. Furthermore, shale oil and shale gas are the most rapidly expanding trends in unconventional oil and gas. Shales are notorious for their strong elastic anisotropy, i.e., so‐called vertical transverse isotropy. This vertical transverse isotropy, characterised by a vertical axis of invariance, is of practical importance as it is required for correct surface seismic data interpretation, seismic to well tie, and amplitude versus offset analysis. A rather classical paradigm makes a clear link between compaction in shales and the alignment of the clay platelets (main constituent of shales). This would imply increasing anisotropy strength with increasing compaction. Our main purpose is to check this prediction on two large databases in shaly formations (more than 800 samples from depths of 0–6 km) by extracting the major trends in the relation between seismic anisotropy and compaction. The statistical analysis of the database shows that the simultaneous increase in density and velocity, a classical compaction signature, is quite weakly correlated with the anisotropy strength. As a consequence, compaction can be excluded as a major cause of seismic anisotropy, at least in shaly formations. Also, the alignment of the clay platelets can explain most of the anisotropy measurements of both databases. Finally, a method for estimating the orientation distribution function of the clay platelets from the measurement of the anisotropy parameters is suggested.

Published: January 2017

AbstractPathological diagnosis of drowning remains a challenge for forensic science, because of a lack of pathognomonic findings. We analyzed microbiota and surfactant protein in the lungs for a novel diagnosis of drowning. All rats were divided into drowning, postmortem submersion, and control groups. The water, lungs, closed organs (kidney and liver), and cardiac blood in rats were assayed by targeting 16S ribosomal RNA of Miseq sequencing. Lung samples were analyzed by immunohistochemical staining for surfactant protein A. The closed organs and cardiac blood of drowned group have a lot of aquatic microbes, which have not been detected in postmortem submersion group. Furthermore, intra‐alveolar granular staining of surfactant protein A (SP‐A) was severely observed in the drowned group than the postmortem submersion and control groups. The findings suggested that the presence of aquatic microbiota in the closed organs and increased expression of SP‐A could be markers for a diagnosis of drowning.

Published: January 2017

AbstractIntroductionWe aimed to investigate if labor onset before planned cesarean delivery (CD) affects the risk of neonatal admission, respiratory distress, or neonatal infectious morbidity.Material and methodsOur cohort included singleton term pregnant women with intended CD who delivered at Aarhus University Hospital from 1990 to 2012. Two groups of women were identified: women with intended CD performed before labor (nonlabor CD) and women with intended CD performed after spontaneous labor onset (labor‐onset CD); in both groups there was no other maternal or fetal medical indication for an immediate CD or for early‐term CD scheduling. Data were stratified in early‐term (37–38 weeks) and full‐term (39–40 weeks) deliveries. The main outcome measures were neonatal admission, respiratory distress and neonatal infectious morbidity.ResultsAmong 103 919 live births, 5071 deliveries were nonlabor CDs and 731 were labor‐onset CDs. Compared to nonlabor CD, labor‐onset CD was associated with similar risks of neonatal admission and respiratory distress, both at early and full term, but with a two‐ to three‐fold increased risk of newborn septicemia or antibiotic treatment at early term. Labor onset at early term was associated with a lower risk of maternal blood loss of more than 500 mL, but with a higher risk of postoperative antibiotic treatment and endometritis.ConclusionsLabor onset before planned CD was not associated with a decrease in neonatal respiratory morbidity, but may be associated with increased risks of neonatal infection.
Mathematical Modeling of Rotary Blood Pumps in a Pulsatile In Vitro Flow Environment
Authors: Pirbodaghi Tohid 
Published: January 2017

AbstractNowadays, sacrificing animals to develop medical devices and receive regulatory approval has become more common, which increases ethical concerns. Although in vivo tests are necessary for development and evaluation of new devices, nonetheless, with appropriate in vitro setups and mathematical models, a part of the validation process can be performed using these models to reduce the number of sacrificed animals. The main aim of this study is to present a mathematical model simulating the hydrodynamic function of a rotary blood pump (RBP) in a pulsatile in vitro flow environment. This model relates the pressure head of the RBP to the flow rate, rotational speed, and time derivatives of flow rate and rotational speed. To identify the model parameters, an in vitro setup was constructed consisting of a piston pump, a compliance chamber, a throttle, a buffer reservoir, and the CentriMag RBP. A 40% glycerin–water mixture as a blood analog fluid and deionized water were used in the hydraulic circuit to investigate the effect of viscosity and density of the working fluid on the model parameters. First, model variables were physically measured and digitally acquired. Second, an identification algorithm based on regression analysis was used to derive the model parameters. Third, the completed model was validated with a totally different set of in vitro data. The model is usable for both mathematical simulations of the interaction between the pump and heart and indirect pressure measurement in a clinical context.
Engaging with environmental stakeholders: Routes to building environmental capabilities in the context of the low carbon economy
Authors: Baranova Polina , Meadows Maureen 
Published: January 2017

AbstractThe transition to a low carbon economy demands new strategies to enable organizations to take advantage of the potential for “green” growth. An organization's environmental stakeholders can provide opportunities for growth and support the success of its low carbon strategies, as well as potentially acting as a constraint on new initiatives. Building environmental capabilities through engagement with environmental stakeholders is conceptualized as an important aspect for the success of organizational low carbon strategies. We examine capability building across a range of sectors affected by the sustainability agenda, including construction, rail, water, and health care. We identify a number of emergent environmental stakeholders and explore their engagement with the development of environmental capabilities in the context of the transition toward a low carbon economy. Our conceptual framework offers a categorization of environmental stakeholders based on their position in relation to a focal organization and the potential for the development of environmental capabilities.
