A multiple-attribute decision-making method based on the mean value of grey number weight optimisation and its application in supply-chain management
Authors: Mi Chuanmin , Xiao Lin , Liu Sifeng , Ruan Xiaoyan 
Published: June 2017

Purpose
With respect to the multiple-attribute decision-making problem with subjective preference for a certain attribute whose weight-value range have been given over other attributes whose weight values are unknown, a method based on the mean value of the grey number is proposed to analyse the decision-making problem. This method is used to choose a supply-chain partner under the condition that the decision makers have a preference for a certain attribute of various alternatives. The paper aims to discuss these issues.

Design/methodology/approach
First, the middle value of the preferred attribute’s weight-value range is supposed to be its weight value according to the content of the mean value of the grey number. Second, to reflect the decision maker’s subjective preference information, an improved optimisation model that requests the minimum deviation between the actual and expected numerical value of each attribute is constructed to assess the attributes’ weights. Third, the correlated degree and the correlation matrix, which are determined by the weight values of all attributes, are used to rank all the alternatives.

Findings
This paper provides a method for making a decision when decision makers have a preference for a certain attribute from an array of various alternatives, and the range of the certain attribute’s weight value is given but the weight value of the other attributes is unknown. When applied to supply-chain partner selection, this method proves feasible and effective.

Practical implications
This method is feasible and effective when applied to supply-chain partner selection, and can be applied to other kinds of decision-making problems. This means it has significant theoretical importance and extensive practical value.

Originality/value
Based on the mean value of the grey number, an optimisation model is built to determine the importance degree of each attribute, then the correlated degree of each alternative is combined to rank all the alternatives. This method can suit the decision makers’ subjective preference for a certain attribute well.
Team faultline: types, configuration and influence – evidence from China
Authors: Zhang Jing , Liang Qiaozhuan , Zhang Yue , Qu Yuanmei (Elly) 
Published: June 2017

PurposeThis study aims to focus on three types of team faultlines (separation-based faultlines, variety-based faultlines and disparity-based faultlines) and discuss the different ways through which their configurational properties (faultline strength and faultline distance) affect team performance.Design/methodology/approachThe authors adopted panel data regression analysis to test the model. Panel data of Chinese provincial party-government top cadres teams that covers 30 provincial areas from 2007 to 2012 were collected for data analyses.FindingsThe results revealed that separation-based faultline strength was negatively related to team performance, variety-based faultline strength had a U-shape relationship with team performance and disparity-based faultline strength had an inversed U-shape relationship with team performance. In addition, separation-based and disparity-based faultline distances served as moderators enhancing the curvilinear relationship between faultline strength and team performance. Notably, variety-based faultline distance failed to exaggerate the U-shape relationship between variety-based faultline strength and team performance; however, the relationship changed based on different levels of variety-based faultline distance.Originality/valueThis study discussed team configurations based on three types of faultlines by comparing differences between team configurations reflected by diversity and faultline strength. Settled in Chinese political context, this study empirically tested the interaction effects between faultline strength and distance on team performance.
Value creation and appropriation in product returns management
Authors: Dapiran G. Peter , Kam Booi H. 
Published: June 2017

Purpose
Product returns management (PRM) is a core supply chain management process. Though the importance of value creation and appropriation is acknowledged, extant studies on value in product returns tend to be limited to the residual asset value (cost recovery) of the returned products. Further, value discussion in PRM is limited to the value implications for a single party in the returns transaction rather than all the product returns chain entities. The purpose of this paper is to explore value creation and appropriation in a triad of supplier-retailer-3PL in the product returns chain.

Design/methodology/approach
The study uses an inductive qualitative approach. Semi-structured interviews with executives in a triad of organisations formed the primary data source for the study.

Findings
The paper identifies six value drivers and develops a value creation and appropriation framework. It shows that facilitation, value orientation, process alignment and relational factors are key drivers of value creation and appropriation in PRM.

Research limitations/implications
The findings reinforce the view that value creation and appropriation are the outcomes of multi-party interactions in a product return chain. The framework presented contributes to the literature by showing the linkages amongst key drivers.

Practical implications
The findings show the important role of external process facilitation and how a 3PL contributes to value creation in a triadic relationship.

Originality/value
Research based on a triadic product returns chain is a unique dimension of this study.

Legitimacy judgments in neighborhood context
Authors: Kochel Tammy Rinehart 
Published: June 2017

Purpose
Policing differs across neighborhoods, but little is known about how context conditions residents’ assessments about police legitimacy. The purpose of this paper is to investigate whether procedural justice and police effectiveness differently contribute to legitimacy judgments depending on the security risk inherent in the context.

Design/methodology/approach
The research applies a series of multi-level regression models using nearly 3,000 surveys of Trinidad and Tobago residents.

Findings
Police legitimacy and the conditions that promote legitimacy vary across neighborhoods. In “good” neighborhoods, individuals draw on police effectiveness and procedural justice to infer legitimacy, but in at-risk neighborhoods, residents’ views derive from effectiveness. Procedural justice does not play a significant role.

Practical implications
One implication for police is that the current emphasis on evidence-based policing strategies, especially in high crime neighborhoods, can provide a mechanism to improve the generally negative views about police legitimacy held by those residents. The findings do not imply, however, that police need not be concerned about procedural justice in at-risk neighborhoods. In fact, as police improve their crime prevention prowess, views about how procedurally just their methods are increase in importance.

Originality/value
Prior research addressing the antecedents of legitimacy has focused on individual demographic and attitudinal predictors. Only two prior studies have begun to investigate whether residents of different contexts may form their views based on different antecedents. This study outlines a theoretical basis for why different bases may be expected and then tests those expectations using rigorous statistical analyses.
Studies on N‐Acetyltransferase (NAT2) Genotype Relationships in Emiratis: Confirmation of the Existence of Phenotype Variation among Slow Acetylators

Published: June 2017

AbstractBackground and purposeIndividuals with slow N‐acetylation phenotype often experience toxicity from drugs such as isoniazid, sulfonamides, procainamide, and hydralazine, whereas rapid acetylators may not respond to these medications. The highly polymorphic N‐acetyltransferase 2 enzyme encoded by the NAT2 gene is one of the N‐acetylators in humans with a clear impact on the metabolism of a significant number of important drugs. However, there are limited studies on N‐acetylation phenotypes and NAT2 genotypes among Emiratis, and thus this study was carried out to fill this gap.MethodsFive hundred seventy‐six Emirati subjects were asked to consume a soft drink containing caffeine (a nontoxic and reliable probe for predicting the acetylation phenotype) and then provide a buccal swab along with a spot urine sample. Polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) was used to determine the genotype of each individual. Phenotyping was carried out by analyzing the caffeine metabolites using high‐performance liquid chromatography (HPLC) analysis.ResultsWe found that 78.5%, 19.1%, and 2.4% of the Emirati subjects were slow, intermediate, and rapid acetylators, respectively. In addition, we found that 77.4% of the subjects were homozygous or heterozygous for two nonreference alleles, whereas 18.4% and 4.2% were heterozygous or homozygous for the reference allele (NAT2*4), respectively. The most common genotypes found were NAT2*5B/*7B, NAT2*5B/*6A, NAT2*7B/*14B, and NAT2*4/*5B, with frequencies of 0.255, 0.135, 0.105, and 0.09, respectively. The degree of phenotype/genotype concordance was 96.2%. The NAT2*6A/*6A, NAT2*6A/*7B, NAT2*7B/*7B, and NAT2*5A/*5B genotypes were found to be associated with the lowest 5‐acetylamino‐6‐formylamino‐3‐methyluracil/1‐methylxanthine (AFMU/1X) ratios.ConclusionsThere is a high percentage of slow acetylators among Emiratis, which correlates with the presence of nonreference alleles for the NAT2 gene. Individuals who carried NAT2*6A/*6A, NAT2*6A/*7B, NAT2*7B/*7B, or NAT2*5A/*5B genotypes might be at higher risk of toxicity with some drugs and some diseases compared to others, as these genotypes are associated with the slowest acetylation status.

Published: June 2017

SummaryBackgroundUlcerative colitis (UC) and Crohn's disease (CD) are inflammatory bowel diseases (IBD). Evidence implicates disturbances of the gastrointestinal microbiota in their pathogenesis.AimTo perform a systematic review and meta‐analysis to examine the efficacy of probiotics in IBD.MethodsMEDLINE, EMBASE, and the Cochrane Controlled Trials Register were searched (until November 2016). Eligible randomised controlled trials (RCTs) recruited adults with UC or CD, and compared probiotics with 5‐aminosalicylates (5‐ASAs) or placebo. Dichotomous symptom data were pooled to obtain a relative risk (RR) of failure to achieve remission in active IBD, or RR of relapse of disease activity in quiescent IBD, with 95% confidence intervals (CIs).ResultsThe search identified 12 253 citations. Twenty‐two RCTs were eligible. There was no benefit of probiotics over placebo in inducing remission in active UC (RR of failure to achieve remission=0.86; 95% CI=0.68‐1.08). However, when only trials of VSL#3 were considered there appeared to be a benefit (RR=0.74; 95% CI=0.63‐0.87). Probiotics appeared equivalent to 5‐ASAs in preventing UC relapse (RR=1.02; 95% CI=0.85‐1.23). There was no benefit of probiotics in inducing remission of active CD, in preventing relapse of quiescent CD, or in preventing relapse of CD after surgically induced remission.ConclusionsVSL#3 may be effective in inducing remission in active UC. Probiotics may be as effective as 5‐ASAs in preventing relapse of quiescent UC. The efficacy of probiotics in CD remains uncertain, and more evidence from RCTs is required before their utility is known.
Multiple Phenotype Association Tests Using Summary Statistics in Genome-wide Association Studies
Authors: Liu Zhonghua , Lin Xihong 
Published: June 2017

Summary
We study in this article jointly testing the associations of a genetic variant with correlated multiple phenotypes using the summary statistics of individual phenotype analysis from Genome-Wide Association Studies (GWASs). We estimated the between-phenotype correlation matrix using the summary statistics of individual phenotype GWAS analyses, and developed genetic association tests for multiple phenotypes by accounting for between-phenotype correlation without the need to access individual-level data. Since genetic variants often affect multiple phenotypes differently across the genome and the between-phenotype correlation can be arbitrary, we proposed robust and powerful multiple phenotype testing procedures by jointly testing a common mean and a variance component in linear mixed models for summary statistics. We computed the p-values of the proposed tests analytically. This computational advantage makes our methods practically appealing in large-scale GWASs. We performed simulation studies to show that the proposed tests maintained correct type I error rates, and to compare their powers in various settings with the existing methods. We applied the proposed tests to a GWAS Global Lipids Genetics Consortium summary statistics data set and identified additional genetic variants that were missed by the original single-trait analysis.
Evaluating Principal Surrogate Markers in Vaccine Trials in the Presence of Multiphase Sampling
Authors: Huang Ying 
Published: June 2017

SummaryThis article focuses on the evaluation of vaccine-induced immune responses as principal surrogate markers for predicting a given vaccine's effect on the clinical endpoint of interest. To address the problem of missing potential outcomes under the principal surrogate framework, we can utilize baseline predictors of the immune biomarker(s) or vaccinate uninfected placebo recipients at the end of the trial and measure their immune biomarkers. Examples of good baseline predictors are baseline immune responses when subjects enrolled in the trial have been previously exposed to the same antigen, as in our motivating application of the Zostavax Efficacy and Safety Trial (ZEST). However, laboratory assays of these baseline predictors are expensive and therefore their subsampling among participants is commonly performed. In this article, we develop a methodology for estimating principal surrogate values in the presence of baseline predictor subsampling. Under a multiphase sampling framework, we propose a semiparametric pseudo-score estimator based on conditional likelihood and also develop several alternative semiparametric pseudo-score or estimated likelihood estimators. We derive corresponding asymptotic theories and analytic variance formulas for these estimators. Through extensive numeric studies, we demonstrate good finite sample performance of these estimators and the efficiency advantage of the proposed pseudo-score estimator in various sampling schemes. We illustrate the application of our proposed estimators using data from an immune biomarker study nested within the ZEST trial.
Governance in Canadian Agriculture
Authors: Hedley Douglas D. 
Published: June 2017

AbstractThis paper discusses three broad topics in the development of agricultural and food policies in Canada over the past 150 years. They provide the historical backdrop for these policies in place today and the contorted path they have followed over the years. In some cases, the causes lie outside of agriculture and food, and outside of Canada while in others, the causes lie entirely within the constitutional framework for the agriculture and food industry. The first issue explores the changes in the federal–provincial–territorial relationship in policy constructs for agriculture. Equally, the internal trade arrangements within Canada are explored from this aspect. Tracing the origins of this issue requires exploration of the history, design, and interpretation of the Canadian constitution. The second issue traces the changing role of government in society and the economy and its impact on agriculture and food policy. These changes are not specific to Canada since several countries and international relationships were based on the evolving role of government in the economy and society and its implications for agriculture policy and institutions. The third topic discusses the role that trade and trade agreements have made in Canada's approach to agricultural and food policy development. The emphasis in this topic is on the policies of the past 30 or more years as international agreements began the slow process of liberalizing trade in agriculture and food products. All three of these broad topics are closely linked, providing a mosaic for the understanding of where we have been as a nation and the framework that has emerged today for the agriculture and food industry.
Assessing Equity in Protected Area Governance: Approaches to Promote Just and Effective Conservation
Authors: Dawson Neil , Martin Adrian , Danielsen Finn 
Published: June 2017

AbstractWith the inclusion of equity concerns in Aichi Target 11 of the Convention on Biological Diversity, equitable management has become an important objective for the world's protected areas. The way equity is defined and operationalized influences whether this strategic shift can help identify pathways commensurate with conservation effectiveness. We examined equity around a protected area in Laos, combining quantitative and qualitative methods to explore the three dimensions of procedure, recognition, and distribution. Local understandings of equity depended on discrete, evolving issues, with attention to informal decision making and dynamic values required to uncover suitable solutions. We show that equity definitions focused on material distribution and assessments reliant on standardized indicators may result in inadequate responses that sustain local perceptions of inequitable management and miss opportunities for effective conservation. Equity should be considered a management goal to continually adapt toward, informed by stakeholder dialogue.
Face à un marché du travail saturé: les compétences qui protègent

Published: June 2017

RésuméLes auteurs s'intéressent aux situations de surqualification et de chômage chez les jeunes diplômés du supérieur dans dix‐sept pays européens en analysant le rôle à cet égard des compétences ≪spécialisées≫ et des compétences ≪universitaires de base≫. Conformément à la thèse de l'éviction, les compétences spécialisées protègent davantage de la surqualification quand la surabondance de main‐d'œuvre s'accroît dans le secteur professionnel lié à la spécialisation du diplômé, et les compétences de base davantage si c'est sur le marché du travail général que cet excédent se renforce. En outre, si les compétences spécialisées protègent du chômage, les compétences de base restent sans effet sur ce risque.

Published: June 2017

ResumenCon datos de los inicios profesionales de titulados universitarios europeos y japoneses, se investiga el papel de las instituciones y los desequilibrios del mercado laboral en el desajuste vertical, horizontal y total de las calificaciones. El horizontal resulta menor en países con mucha protección del empleo, mejores subsidios de desempleo y programas educativos selectivos. Las diferencias entre países en cuanto al vertical se explican por los desequilibrios del mercado laboral. Estas variables afectan también al desajuste total, que además correlaciona positivamente con la cobertura de la negociación colectiva. Las diferencias según la carrera estudiada tienen que ver con las características de los currículos y también con los desequilibrios del mercado.
