Non-Muslims’ acceptance of imported products with halal logo
Authors: Kawata Yukichika , Htay Sheila Nu Nu , Salman Ahmed  Syed 
Published: December 2017

Purpose
This study aims to examine whether citizens of non-Muslim countries accept products with a “halal” logo. In the era of globalization, one of the most crucial issues for Muslim travelers is reliable halal foods when visiting non-Muslim countries. If people in non-Muslim countries accept imported products containing halal certification logos, and such products are readily available in shops, this issue could be substantially improved.

Design/methodology/approach
Malaysia and Japan were selected as Muslim and non-Muslim countries, respectively, to conduct a choice experiment (CE) for 656 non-Muslim subjects, and estimated willingness to pay (WTP) for mineral water with and without the halal logo. A random parameter logit model was used for estimation.

Findings
The difference between the WTP for mineral water with and without the halal logo was ¥5; however, the associated coefficient is not statistically significant. This implies that the halal logo has no impact on non-Muslim subjects’ purchasing behavior. From this, we can infer that the halal products with certification logo would be accepted in Japanese shops, which may foster foreign Muslim visits.

Research limitations/implications
As the results are based on a couple of countries (Malaysia and Japan) and only one product (mineral water), further investigation using other products in different countries would be necessary. However, as suggested in the main text, the results enjoy a degree of generalizability.

Originality/value
The results of this study support the possibility of circulating halal products in non-Muslim countries and thus promoting Muslim travel abroad. No such study has examined this issue using CE.
Islamic human resource management (iHRM) enhancing organizational justice and employees’ commitment
Authors: Fesharaki Farzad , Sehhat Saied 
Published: December 2017

Purpose
This paper aims to introduce and promote the novel concept of Islamic human resource management (iHRM) and assess its effects upon two organizational attitudes, namely, perceived justice and employees’ commitment.

Design/methodology/approach
The present study is an applicable and empirical research that has used the descriptive–correlative method. The target population consists of 192 employees from Resalat Qard al-Hasan Bank in the city of Tehran. Calculated based on Cochran’s formula, 128 people are selected by means of a simple random sampling technique. To collect primary filed data, questionnaires are distributed. The gathered responses are analyzed with the structural equation modeling approach using SmartPLS software package.

Findings
Four dimensions of iHRM, i.e. recruitment and selection, training and development, remuneration and compensation and performance appraisal, are positively associated with organizational justice. Also the first three dimensions have a positive impact on employees’ commitment, but the link between performance appraisal and employees’ commitment is not statistically significant because of the slightly negative attitude of the employees toward a possible perfunctory routine.

Originality/value
iHRM is one of the emerging trends in Islamic management literature, with limited studies conducted in this specific field. The current effort is one of the first attempts to empirically investigate this relatively new construct in the context of Iran.
Are the new fuel-efficient bulkers a threat to the old fleet?
Authors: Pruyn Jeroen 
Published: December 2017

Purpose
The purpose of this paper is to investigate whether the headlined eco-bulkers ordered in 2012 and 2013 are posing a threat to the less-efficient ships ordered at the end of the boom in 2008 and 2009.

Design/methodology/approach
This paper will first investigate the drivers for the interest in such low-emission, low-speed bulker as well as the more general history of bulker designs. This is followed by a study on the vessels delivered between 2005 and 2014, based on eight parameters representing fuel efficiency, speed and hydromechanics properties. Within these results, evidence is sought for a significant change in the qualities of the vessels delivered after the last boom.

Findings
The data showed that at least till present, no significant changes could be discovered between 2014 and the earlier years. This indicates that either because of the long delivery times at the end of the boom, such vessels are still to be delivered, or that they were not ordered in an amount large enough to change the trend. For the future, this fact and the changes in vessel design resulting from the introduction of the energy efficiency design index (EEDI) in 2017 and the large fluctuations in the fuel prices will be interesting to keep monitoring the developments in the eight studied parameters.

Originality/value
This paper extends (in time) and improves (number of variables studied) a number of earlier studies on average qualities of the world fleet. It studies both the composition and the changes in average properties of the ships produced each year. It allowed the author to discover and explain the trends that would not have been evident when studying ships as single units or as the result of a business opportunity optimisation. Most important of which is the fact that, on average, ships produced are optimised for the current economic conditions and are not taken into consideration for future trends and scenarios.
Performance obligations for “revenue from contracts with customers” principle in the shipping industry
Authors: Duru Okan , Mileski Joan P. , Gunes Ergun 
Published: December 2017

Purpose
The aim of this paper is to investigate the gap between cost-based and time-based revenue recognition schemes in the accounting of ship-owning corporations, and to propose cost-based revenue recognition (as in general accounting practice) in connection with the performance obligations.

Design/methodology/approach
For a comparative analysis of time-based (traditional approach) and cost-based schemes, a sample of dry bulk ships is selected and voyage estimations are performed by certified professional shipbrokers (Fellow of the Institute of Chartered Shipbrokers) (data collection and voyage estimation by practitioner). Performance obligations are also defined by certified shipbrokers (i.e. survey and expert opinion) and certified public accountant based on common shipping business practice and accounting practice in general.

Findings
Empirical results indicate the significant gap between two alternative schemes. Cost-based revenue recognition accelerates the revenue recognition (benefit of shipowner), and it enables comparability among other industries since cost-based allocation is the common practice in accounting (matching principle, Generally Accepted Accounting Principles).

Research limitations/implications
It is obviously impossible to observe all kinds of freight market transactions for all different kinds of vessel particulars. The sample size does not undervalue the current study since the central idea of this paper is not the verification of the cost-based recognition in all possible transactions.

Practical implications
The proposed approach debiases the existing recognition practice as well as improving the speed of revenue recognition. In the existing practice, time-based recognition is still based on voyage estimations (time estimation). Voyage estimations conventionally answer two questions: “What is the cost of the voyage?” and “What is the duration of the voyage?” Therefore, the proposed approach does not require any additional work done. Common practice also clarifies the cost-based schedule for revenue recognition.

Originality/value
This paper addresses the unconventional accounting practice and its incomparability problem for the first time. To the best of the authors’ knowledge, this paper is also the first study on accounting economics of the shipping business. This paper proposes a practical solution to the debate raised by Financial Accounting Standards Board 2014-09 regulation on accounting standards by utilizing a staging approach and cost-based revenue allocation.
A tale of two studies: Detection and attribution of the impacts of invasive plants in observational surveys
Authors: Mueller Kevin E. , Lodge Alexandra G. , Roth Alexander M. , Whitfeld Timothy J. S. , Hobbie Sarah E. , Reich Peter B. 
Published: December 2017

Abstract

Short‐term experiments cannot characterize how long‐lived, invasive shrubs influence ecological properties that can be slow to change, including native diversity and soil fertility. Observational studies are thus necessary, but often suffer from methodological issues.

To highlight ways of improving the design and interpretation of observational studies that assess the impacts of invasive plants, we compare two studies of nutrient cycling and earthworms along two separate gradients of invasive shrub abundance. By considering the divergent sampling strategies and statistical analyses of these two studies, and interpreting their contradictory results in the context of other studies, we also aim to better describe the impacts of the focal invader, Rhamnus cathartica.

In a new study of a single site in Minnesota, we observed positive correlations between buckthorn abundance and soil pH, soil nutrient pools, nutrient fluxes through leaf litterfall, earthworm abundance and root biomass. Multiple regression models showed these relationships persisted after accounting for variability in soil texture and tree species composition. For a separate, more expansive study in Illinois, other authors reported little to no correlation between buckthorn abundance and 10 soil properties, including earthworm abundance, pH and nutrient concentrations. However, like many other studies, their regression models only assessed predictors related to invader abundance. R2‐values for models of ecosystem properties ranged from 0 to .79 (adjusted‐R2) for our study in Minnesota and from <.05 to .16 (unadjusted) for the prior study in Illinois.

Differences in sampling error and use of predictor variables between the two studies likely explain the contrasting results.

Synthesis and applications. To reduce the uncertainty of conclusions from observational studies of invasive plants, future studies must ensure that heterogeneity of soils and vegetation is adequately accounted for in the sampling strategy and statistical analyses (e.g. analysis of covariance, multiple regression). Particular attention should be given to ecosystem properties with variability that likely pre‐dates the invader (e.g. geophysical features and tree community composition). In our study, effects of buckthorn on ecosystem properties were not only robust to the inclusion of potentially confounding predictors, but also consistent with expectations based on ecological stoichiometry and mass balance of element flow.
Anthony King: His Intellectual Legacy. Introduction
Authors: Grant Wyn , Ware Alan 
Published: December 2017

AbstractThe Department of Government at Essex University provided a favourable environment for the development of Anthony King's work. While his primary interest was the UK, his intellectual interests were far broader in scope and informed by comparative insights. His key work was on political leadership, but he also made crucial contributions on other issues such as ungovernability. He had a particular concern with the quality of government, reflected in the Blunders book he wrote with Ivor Crewe.
Semicontinuous sophorolipid fermentation using a novel bioreactor with dual ventilation pipes and dual sieve‐plates coupled with a novel separation system

Published: December 2017

SummarySophorolipids (SLs) are biosurfactants with widespread applications. The yield and purity of SLs are two important factors to be considered during their commercial large‐scale production. Notably, SL accumulation causes an increase in viscosity, decrease in dissolved oxygen and product inhibition in the fermentation medium. This inhibits the further production and purification of SLs. This describes the development of a novel integrated system for SL production using Candida albicans O‐13‐1. Semicontinuous fermentation was performed using a novel bioreactor with dual ventilation pipes and dual sieve‐plates (DVDSB). SLs were separated and recovered using a newly designed two‐stage separation system. After SL recovery, the fermentation broth containing residual glucose and oleic acid was recycled back into the bioreactor. This novel approach considerably alleviated the problem of product inhibition and accelerated the rate of substrate utilization. Production of SLs achieved was 477 g l−1, while their productivity was 1.59 g l−1 h−1. Purity of SLs improved by 23.3%, from 60% to 74%, using DVDSB with the separation system. The conversion rate of carbon source increased from 0.5 g g−1 (in the batch fermentation) to 0.6 g g−1. These results indicated that the integrated system could improve the efficiency of production and purity of SLs.

Published: December 2017

AbstractAimTo identify factors found in the research literature to be associated with smoking cessation in pregnancy.MethodsElectronic searches of the bibliographic databases of PubMed, EMBASE, PsycINFO, Elsevier, Scopus and ISI Web of Science were conducted to April 2017. All studies reporting factors associated with smoking cessation or continuing smoking during pregnancy were included and reviewed systematically, irrespective of study design. The Newcastle–Ottawa Quality Assessment Scale was used to assess the study quality. The DerSimonian & Laird random‐effects model was used to conduct meta‐analyses, and where effect estimates were reported for factors included in at least three studies.ResultsFifty‐four studies, including 505 584 women globally who smoked before pregnancy, 15 clinical trials and 40 observational studies, were included in the review and 36 (65.5%) were considered to be of high quality. This review identified 11 socio‐demographic, seven socially related, 19 smoking behaviour‐related, five pregnancy‐related, six health‐related and six psychological factors that were associated significantly with smoking cessation during pregnancy. The most frequently observed significant factors associated with cessation were: higher level of education, pooled odds ratio (OR), 95% confidence interval (CI) = 2.16 (1.80–2.84), higher socio‐economic status: 1.97 (1.20–3.24), overseas maternal birth: 2.00 (1.40–2.84), Medicaid coverage or private insurance: 1.54 (1.29–1.85), living with partner or married: 1.49 (1.38–1.61), partner/other members of the household do not smoke: 0.42 (0.35–0.50), lower heaviness of smoking index score: 0.45 (0.27–0.77, lower baseline cotinine level: 0.78 (0.64–0.94), low exposure to second‐hand smoking: 0.45 (0.20–1.02), not consuming alcohol before and/or during pregnancy: 2.03 (1.47–2.80), primiparity: 1.85 (1.68–2.05), planned breastfeeding:1.99 (1.94–2.05), perceived adequate pre‐natal care: 1.74 (1.38–2.19), no depression: 2.65 (1.62–4.30) and low stress during pregnancy: 0.58 (0.44–0.77).ConclusionA wide range of socio‐demographics, relationship, social, smoking‐related, pregnancy‐related, health and psychological factors have been found to predict smoking cessation in pregnancy.

Published: December 2017

AbstractLearners who enrol in massive open online courses (MOOCs) have different backgrounds and tend to have different motivations than learners in traditional courses. Based on value‐expectancy theory, an instrument was developed to measure motivation for enrolling in a programming MOOC. A study with 1229 adult participants in Estonian‐language programming course “About Programming” was conducted to validate the instrument. Results of confirmatory factor analysis validated the 7‐factor scale named factors influencing enrolment in MOOC (FIEM). FIEM comprises three factors of expectancies, three factors of values and one factor of social influence. The highest and lowest rated motivational factors influencing enrolment in programming MOOC are discussed in the paper. Interest in and expectations for the course, personal suitability of distance learning and suitability for family and work are the highest‐rated motivational factors for those who enrol in MOOC. Usefulness related to own children, social influence and usefulness to related to certification were the lowest rated. The results of this study can be useful for designers of programming MOOCs and the developed scale might be used in future studies.

India's integrated child development services scheme: challenges for scaling up
Authors: Rao N. , Kaul V. 
Published: December 2017

AbstractBackgroundIndia had around 158 million children under the age of 6 and about 26 million births in 2015. In the same year, India's Integrated Child Development Services Scheme served about 82 million children under 6 years and over 19 million pregnant women and lactating mothers. These 102 million beneficiaries received services in about 1.3 million centres.MethodThis paper reviews the growth of the Scheme and considers challenges to scaling up quality with equity based on results of large‐scale national or multistate studies.ResultsThe Scheme is associated with decreased malnutrition and better child development. The size and diversity of the country, the policy context, funding mode and lack of community awareness and engagement have hindered scaling up access while the approach to service delivery, low institutional capacity and poor infrastructure have impeded scaling up of implementation quality.ConclusionsThis review illustrates the challenges associated with scaling‐up access and implementation quality of a multicomponent, integrated early childhood programme in a large, diverse country. The future success of the Integrated Child Development Services will depend on how well it adheres to quality standards and how well it evolves to address current weaknesses.

Published: December 2017

ObjectiveTo investigate the headache characteristics and clinical features of elderly migraine patients at a tertiary headache center.MethodsWe retrospectively reviewed 239 records of migraine patients, over the age of 64 at the first visit, who had migraine as defined by the International Classification of Headache Disorders 3rd edition (beta version) from 2006 to 2015 based on the Marseille registry at Timone Hospital.Results13.8% (33/239) patients had migraine with aura only, 13.0% (31/239) had both diagnoses. Of the patients who presented with migraine with aura, 13.4% (32/239) presented with aura without headache. Unilateral pain location was reported by 58.6% (140/239) of patients and the throbbing type of pain was present in 50.2% (120/239) of our study group. Photo‐ and phonophobia were observed in 77.4% (185/239) and 79.5% (190/239) of patients. Seventy‐nine out of 239 (30.1%) patients were found to have probable medication overuse. Within this group, 31.65% (25/79) overused triptan and 70.9% (56/79) overused combination analgesics. We found higher frequencies of migraine for patients whose age at onset of migraine was younger than 18 years, and low frequency migraine was reported more frequently in the later onset group (P = .0357).DiscussionWe assess the headache characteristics of elderly migraine patients who were seen at our tertiary headache center and report the high frequency of probable medication overuse headache in this study group. Finally, we suggest that age of onset is an important factor in the clinical profile of these patients.
Superoxide dismutase from Helicobacter pylori suppresses the production of pro‐inflammatory cytokines during in vivo infection

Published: December 2017

AbstractBackgroundHelicobacter pylori has undergone considerable adaptation to allow chronic persistence within the gastric environment. While H. pylori‐associated diseases are driven by an excessive inflammation, severe gastritis is detrimental to colonization by this pathogen. Hence, H. pylori has developed strategies to minimize the severity of gastritis it triggers in its host. Superoxide dismutase (SOD) is well known for its role in protecting against oxidative attack; less recognized is its ability to inhibit immunity, shown for SOD from mammalian sources and those of some bacterial species. This study examined whether H. pylori SOD (HpSOD) has the ability to inhibit the host immune response to these bacteria.Materials and MethodsThe ability of recombinant HpSOD to modify the response to LPS was measured using mouse macrophages. A monoclonal antibody against HpSOD was generated and injected into H. pylori‐infected mice.ResultsAddition of HpSOD to cultures of mouse macrophages significantly inhibited the pro‐inflammatory cytokine response to LPS stimulation. A monoclonal antibody was generated that was specific for SOD from H. pylori. When injected into mice infected with H. pylori for 3 months, this antibody was readily detected in both sera and gastric tissues 5 days later. While treatment with anti‐HpSOD had no effect on H. pylori colonization at this time point, it significantly increased the levels of a range of pro‐inflammatory cytokines in the gastric tissues. This did not occur with antibodies against other antioxidant enzymes.ConclusionsSOD from H. pylori can inhibit the production of pro‐inflammatory cytokine during in vivo infection.
