Molecular Epidemiology and Mechanisms of Antibiotic Resistance in Gram-positive Bacteria in Africa: A Systematic Review and Meta-Analysis from a One Health Perspective
Authors: Sekyere John Osei , Mensah JEric 
Published: July 2018

ABSTRACTA systematic review and meta-analysis of antibiotic-resistant Gram-positive bacteria in Africa, showing the molecular epidemiology of resistant species from animal, human and environmental sources, is lacking. Thus, the current burden, type, and sources of Gram-positive bacterial resistance and their dissemination routes from farm to fork is absent. To fill this One Health information gap, we systematically searched PubMed, Web of Science and African Journals Online for English research articles reporting on the resistance mechanisms and clonality of resistant Gram-positive bacteria in Africa within 2007 to 2018. The review and all statistical analysis were undertaken with 130 included articles.From our analyses, the same resistant Gram-positive bacterial clones, resistance genes, and mobile genetic elements (MGEs) are circulating in humans, animals and the environment. The resistance genes, mecA, erm(B), erm(C), tet(M), tet(K), tet(L), vanB, vanA, vanC, and tet(O), were found in isolates from humans, animals and the environment. Commonest clones and mobile genetic elements identified from all three sample sources included Staphylococcus aureus ST5 (n=208 isolates), ST 8 (n=116 isolates), ST 80 (n=123 isolates) and ST 88 (n=105 isolates), and IS16 (n=18 isolates), Tn916 (n=60 isolates) and SCCmec (n=202 isolates). Resistance to penicillin (n=4 224 isolates, 76.2%), erythromycin (n=3 552 isolates, 62.6%), ampicillin (n=1 507 isolates, 54.0%), sulfamethoxazole/trimethoprim (n=2 261 isolates, 46.0%), tetracycline (n=3 054 isolates, 42.1%), vancomycin (n=1 281 isolates, 41.2%), streptomycin (n=1 198 isolates, 37.0%), rifampicin (n=2 645 isolates, 33.1%), ciprofloxacin (n=1 394 isolates, 30.5%), clindamycin (n=1 256 isolates, 29.9%) and gentamicin (n=1 502 isolates, 27.3%) (p-value <0.0001) were commonest.Mean resistance rates of 14.2% to 98.5% were recorded in 20 countries within the study period, which were mediated by clonal, polyclonal and horizontal transmission of resistance genes. A One Health approach to research, surveillance, molecular epidemiology, and antibiotic stewardship to contain ABR should be prioritized.
Sustainable improvement in education
Authors: Myszewski Jan M. 
Published: July 2018

Purpose
Education is a natural process of improvement. Education’s specific features and challenges include a large number of students, with different psychophysical characteristics, simultaneously taking part in a lesson. The purpose of this paper is to examine the factors that can help to meet the challenges of classroom teaching.

Design/methodology/approach
The principle of “equal opportunities in education” is adopted as the basic premise to improve education. The general sustainability model developed by the author is used as a reference model to analyze the sustainability of the education process.

Findings
The following elements of the process of sustainable development in education are defined: the improvement micro-projects, as the basic form of using and developing students’ knowledge, and the principles of sustainable development in the classroom as conditions necessary for the effectiveness of micro-projects, in the teaching process carried out in the classroom. They point to the key role of the teacher as the leader in the improvement process.

Originality/value
The principles of sustainable development define the conditions necessary to ensure the development of the reserve of the students’ knowledge capacity and the possibilities of using it in the classroom teaching process. The micro-project system enables personalization of the teaching process through the use of the capacity reserve contributed by students.

Authors: Aureli Selena , Giampaoli Daniele , Ciambotti Massimo , Bontis Nick 
Published: July 2018

Purpose
The purpose of this paper is to empirically test the knowledge-intensive process of creative problem-solving and its outcomes.

Design/methodology/approach
This study uses survey data from 113 leading Italian companies. To test the structural relations of the research model the authors used the partial least square (PLS) method.

Findings
Results show that work design and training have a positive direct impact on creative problem-solving process while organizational culture has a positive impact on both creative problem-solving process and its outcomes. Finally creative problem-solving process has a strong direct impact on its outcomes and this, in turn, on firms’ competitiveness.

Practical implications
This study suggests that managers must highlight the problem-solving process as it affects a firm’s capability to find creative solutions and therefore its competitiveness. Moreover, the present paper suggests managers should invest in specific knowledge management (KM) practices for enhancing knowledge-intensive business processes.

Originality/value
The present paper fills an important gap in the BPM literature by empirically testing the relationship among KM practices, multistage processes of creative problem-solving and their outcomes, and firms’ competitiveness.
The impact of corporate governance mechanisms on EU banks’ income smoothing behavior
Authors: Vasilakopoulos Konstantinos , Tzovas Christos , Ballas Apostolos 
Published: July 2018

PurposeThis paper aims to investigate the impact that governance mechanisms have on European Union ‘banks income smoothing behavior.Design methodology/approachThe authors examine the impact that corporate governance mechanisms included in European Commissions’ proposals regarding the improvement of corporate governance mechanisms (Green Paper) have upon European Union banks’ accounting policy decisions regarding the level of loan loss provisions (LLPs). In addition, the authors examine whether banks’ capital structure operates as an effective internal corporate governance practice. The authors investigate the association between certain corporate governance characteristics and the level of LLPs for a sample of 98 banks from 23 European Union countries for the period of 2010-2013, in the aftermath of the 2008 financial crisis. To test the hypotheses, a multivariate regression model is run. Similar to previous research, the authors use ordinary least squares analysis to test the results.FindingsEmpirical findings provide evidence that there is a positive association between LLPs and accounting income, implying the existence of an income-smoothing pattern of provisions. In addition, the results suggest that banks managers’ decision to smooth income may differ with regard to the board structure, the level of leverage and the provision of disclosure for remuneration for chief executive officer.Originality/valueThe findings of this study contribute to the existing literature concerning banks’ income smoothing behavior. These findings can be useful to regulators, as the authors provide some evidence regarding the effectiveness of the European Union corporate governance framework.

Authors: Xiang Jing , Chen Yuanming , Wang Shouxu , Wang Chong , He Wei , Zhang Huaiwu , Jin Xiaofeng , Chen Qingguo , Su Xinhong 
Published: July 2018

Purpose
Optimized plating conditions, included proper designs of insulating shield (IS), auxiliary cathode (AC) and different patterns, contribute to the uniformity enhancement of copper deposition.

Design/methodology/approach
Plating experiments were implemented in vertical continuous plating (VCP) line for manufacturing in different conditions. Multiphysics coupling simulation was brought to investigate and predict the plating uniformity improvement of copper pattern. In addition, the numerical model was based on VCP to approach the practical application.

Findings
With disproportionate current distribution, different plating pattern design formed diverse copper thickness distribution (CTD). IS and AC improved plating uniformity of copper pattern because of current redistribution. Moreover, optimized plating condition for effectively depositing more uniformed plating copper layer in varied pattern designs were derived by simulation and verified by plating experiment.

Originality/value
The comparison between experiment and simulation revealed that multiphysics coupling is an efficient, reliable and of course environment-friendly tool to perform research on the uniformity of pattern plating in manufacturing.
Effects of inlet cavitation on swirling flow in draft-tube cone
Authors: Yang Jing , Hu Qingjuan , Wang Zhengwei , Ding Jinghuan , Jiang Xianyu 
Published: July 2018

Purpose
For Francis turbine, the vortex flow in the draft tube plays an important role in the safe and efficient operating of hydraulic turbine. The swirling flow produced at the blade trailing edge at off-design conditions has been proved to be the fundamental reason of the vortex flow. Exploring the swirling flow variations in the non-cavitation flow and cavitation flow field is an effective way to explain the mechanism of the complex unsteady flow in the draft tube.

Design/methodology/approach
The swirling flow in different cavitation evolution stages of varying flow rates was studied. The swirl number, which denotes the strength of the swirling flow, was chosen to systematically analyze the swirling flow changes with the cavitation evolutions. The Zwart–Gerber–Blemari cavitation model and SST turbulence model were used to simulate the two-phase cavitating flow. The finite volume method was used to discrete the equations in the unsteady flow field simulation. The Frozen Rotor Stator scheme was used to transfer the data between the rotor-stator interfaces. The inlet total pressure was set to inlet boundary condition and static pressure was set to outlet boundary condition.

Findings
The results prove that the mutual influences exist between the swirling flow and cavitation. The swirling flow was not only affected by the load but also significantly changed with the cavitation development, because the circumferential velocity decrease and axial velocity increase presented with the cavitation evolution. At the high load conditions, the system stability may improve with the decreasing swirling flow strength.

Research limitations/implications
Further experimental and simulation studies still need to verify and estimate the reasonability of the swirling flow seen as the cavitation inception signal.

Originality/value
One interesting finding is that the swirl number began to change as the inception cavitation appeared. This is meaningful for the cavitation controlling in the Francis turbine.
Pricing strategy for renewable energy source electricity in the competitive hybrid electricity market
Authors: Xie Jiaping , Xia Yu , Liang Ling , Zhang Weisi , Shi Minghong 
Published: July 2018

Purpose
To promote the development of renewable energy, the Chinese Government adopts the policy of Feed-in Tariff and subsidy. However, the high purchase price and the intermittence limit the development of renewable energy source electricity (RES-E). The purpose of this paper is to discuss the pricing strategy for system operators to stimulate the development of the RES-E industry under the scenario of uncertain supply and demand.

Design/methodology/approach
The authors establish a two-echelon supply chain investment model led by a power grid operator considering the uncertainties in both demand and supply, and study the impact of the power purchase price designed by a system operator using Stackelberg’s model.

Findings
There is an optimal capacity for RES-E generators, that is, independent of the market demand. Besides, the optimal order of grid operators is independent of the uncertain RES-E supply and the purchase price of fossil fuel. By properly setting the purchase prices, the system operator can stimulate the capacity investment in renewable energy. Finally, increasing the punishment in power shortage can stimulate the capacity investment in RES-E under certain conditions.

Practical implications
The result of this paper can mitigate the phenomenon of power abandonment in the RES-E industry and promote the grid integration of RES-E.

Originality/value
Both uncertain demand and supply are considered in this paper. A heuristic algorithm is provided to compute the optimal purchase price combination.
Using put option contracts in supply chains to manage demand and supply uncertainty
Authors: Luo Jiarong , Zhang Xiaolin , Wang Chong 
Published: July 2018

Purpose
The purpose of this paper is to value put option contracts in hedging the risks in a supply chain consisting of a component supplier with random yield and a manufacturer facing stochastic demand for end products.

Design/methodology/approach
This paper adopts stochastic inventory theory, game theory, optimization theory and algorithm and MATLAB numerical simulation to investigate the manufacturer’s ordering and the supplier’s production strategies, and to study the coordination and optimization strategies in the context of random yield and demand.

Findings
The authors find that put options can not only facilitate the manufacturer’s order but also the supplier’s production, that is, the manufacturer and the supplier can effectively manage their involved risks and earn more expected profits by adopting put options. Further, the authors find that the single put option contract fails to coordinate such a supply chain. However, when combined with a protocol, it is able to coordinate the supply chain.

Originality/value
This paper is the first effort to study the intersection of put option contracts and random yield in the presence of a spot market. From a new perspective, the authors explore the supply chain coordination. The authors propose a mechanism to coordinate the supply chain under put option contracts.
Understanding social enterprise, social entrepreneurship and the social economy in rural Cambodia
Authors: Lyne Isaac , Ngin Chanrith , Santoyo-Rio Emmanuel 
Published: July 2018

PurposeThis paper critically assesses Western views on the social economy in contrast to everyday realities in a low-income country, and challenges ethnocentric epistemologies in the discourse of social enterprise and social entrepreneurship that is prevalent in international development. It charts the changing trajectory of the social economy and different influences.Design/methodology/approachQualitative data is used to explore views of members of social enterprises in Northern Cambodia. Three enterprises with different characteristics were selected. Semi-structured interviews and a group discussion took place in each case, exploring motivation, values, empowerment, participation, equity, innovation and risk appetite.FindingsThe important roles social enterprises play in rural community development are sometimes at odds with the reasoning of Western development agencies. The social economy in Cambodia is undergoing change with the advancement of capitalist market forces. This suits formal businesses but could exacerbate the exclusion of various community actors.Research limitations/implicationsThree case studies are in close proximity in Northern Cambodia, and the situated dynamics may not transfer well to other contexts. Some limitations are offset by the selection of different types of social enterprises.Practical implicationsThe study gives insights of value to the designers of programmes or projects to support social enterprise who work within international development agencies and non-government organisations. For academics, it offers critical insight into assumptions about social enterprise that emanate from Western management literature.Originality/valueThis paper meets the need for close-up inter-disciplinary work on social enterprise development in under-represented contexts.

Published: July 2018

Purpose
The purpose of this paper is to assess the effect of delaying first pregnancy in reducing burden of unintended pregnancy (UP) among married adolescent girls in urban slums of Bangladesh.

Design/methodology/approach
This cross-sectional survey was conducted among 783 married adolescents in five urban slums of Bangladesh during January 2013–January 2014.

Findings
Half of the respondents’ first pregnancy was reported as unintended. Of the respondents, 58 percent with no school education had experienced UP which was 38 percent among respondents with eight year’s education. Respondents who did not willingly agreed to their marriage experienced more UP (61 percent) than those who were agreed/got married by their own choice (51 percent). Respondents having five years of age difference with their husbands experienced more UP (58 percent) than those with ten years of age difference (46 percent). Respondents aged 14 years at first conception experienced 63 percent UP, while the respondents aged 18 years had 35 percent UP experience. Of the respondents, 66 percent who became pregnant within one year of marriage reported their pregnancy as unintended which was 29 percent among those who delayed their first pregnancy for three years.

Originality/value
Significant association was observed between pregnancy intention with respondents’ educational status (p=0.03), age difference with husbands (p=0.02), age at first conception (p<0.01) and delaying first pregnancy (p<0.001).

Published: July 2018

Purpose
This purpose of this paper is to describe methamphetamine relapse risk, examine the relationship between factors in the dynamic model of relapse and methamphetamine relapse risk.

Design/methodology/approach
A total of 165 clients from the Substance Rehabilitation Center of National Narcotics Board in West Java, Indonesia were recruited. The research instruments included a demographic characteristic questionnaire and eight different tests: Drug Taking Confidence Questionnaire; Stimulant Effect Expectancy Questionnaire; Stage of Change Readiness and Treatment Eagerness Scale version 8.0 for Drug; Coping Strategies Inventory Short Form; Positive Affect and Negative Affect Schedule; Desire for Speed Questionnaire; Social Support Questionnaire; and the Stimulant Relapse Risk Scale. Descriptive statistics were used to analyze the data. Pearson’s product moment correlation was used to test the relationship among variables.

Findings
Clients (63 percent) were at a moderate level of methamphetamine relapse risk (mean=56.33, SD=10.54). Outcome expectancy, positive emotional state, negative emotional state and craving were positive and had a significant correlation with relapse risk (r=0.261, r=0.380, r=0.370, r=0.509, p<0.01, respectively). Self-efficacy was negative and had a significant correlation with relapse risk (r=−0.316, p<0.01). Motivation, coping and social support had no correlation with relapse risk.

Originality/value
Two-thirds of the clients in a rehabilitation center have a tendency to relapse following treatment. Nursing intervention for early detection of methamphetamine relapse risk during treatment by using standardized instruments should be implemented.

Authors: Majumdar Abhijit , Sinha Sanjib 
Published: July 2018

Purpose
Small and medium enterprises (SMEs) of Indian clothing industry have become one of the most important cogs of global fashion supply chain. However, the implementation of green practices is still in the nascent stage. The purpose of this paper is to analyze the important barriers of green supply chain management in Indian clothing SMEs.

Design/methodology/approach
A total of 36 barriers related to green supply chain management (GSCM) practices were identified through exhaustive literature review. Then ten important barriers were shortlisted through questionnaire survey among supply chain practitioners using five-point Likert scale. Finally, interpretive structural modeling technique was used to decipher the contextual relationships among these barriers.

Findings
Complexity of green process and system design and lack of support from regulatory authorities were found to be the barriers having the maximum driving power. Lack of consumer support and high investment and low economic benefits were also found to be important barriers in the way of green practices implementation in clothing SMEs. In contrast, lack of reward systems for suppliers, uncertainty of green outcome, lack of green materials, process and technology and lack of flexibility to switch over to green system were the dependent barriers.

Originality/value
The important barriers of GSCM practices in Indian clothing SMEs have been identified and analyzed. The finding will be helpful in making the Indian clothing SMEs environmentally sustainable by eliminating the important barriers.
