A contingent assessment of the structural and governance characteristics of interconnected dyads in multitier supply chains
Authors: Mahapatra Santosh K. , Narasimhan Ram , Barbieri Paolo 
Published: June 2019

PurposeThe purpose of this paper is to examine the buyer–supplier exchange dynamic in terms of the influence of product and market contingencies on the interfirm connectivity, governance and exchange performance of interconnected dyads in multitier supply chains (MSCs).Design/methodology/approachUsing an inductive approach, the authors analyzed the supply network of a high-end motorcycle manufacturer (OEM). Four sets of “interconnected dyads” constituting four embedded units of analysis were considered, each involving the OEM, its tier 1 and corresponding tier 2 suppliers. These interconnected dyads representing four strategic components and their sub-components offer contrasts in terms of product and market contingencies.FindingsThis analysis reveals that product and market contingencies influence patterns of dependence among firms. These in turn impact interfirm connectivity (i.e. structural characteristic), and the degree of contract formalization, collaboration and concentration of decision-making power (i.e. governance characteristics) in the interconnected dyads. The authors also found that structural and governance aspects can have mutual influence, leading to satisfactory or unsatisfactory outcomes. Propositions synthesizing the relationships among the constructs are developed.Research limitations/implicationsThe constructs and their underlying relationships need to be further refined if we are to devise hypotheses and validate them at a large-scale empirical level.Originality/valueThis is one of the first studies to explore the influence of business contingencies on the complex buyer–supplier exchange dynamic in MSCs having a “beyond the dyad” perspective. The authors address why and how various types of interconnectivity are developed, and how the interplay among interfirm dependence, connectivity and governance influences the suppliers’ performance in the MSCs.
On verifying the authenticity of e-commercial crawling data by a semi-crosschecking method
Authors: Dang Tran Khanh , Pham Duc Minh Chau , Ho Duc Dan 
Published: June 2019

PurposeData crawling in e-commerce for market research often come with the risk of poor authenticity due to modification attacks. The purpose of this paper is to propose a novel data authentication model for such systems.Design/methodology/approachThe data modification problem requires careful examinations in which the data are re-collected to verify their reliability by overlapping the two datasets. This approach is to use different anomaly detection techniques to determine which data are potential for frauds and to be re-collected. The paper also proposes a data selection model using their weights of importance in addition to anomaly detection. The target is to significantly reduce the amount of data in need of verification, but still guarantee that they achieve their high authenticity. Empirical experiments are conducted with real-world datasets to evaluate the efficiency of the proposed scheme.FindingsThe authors examine several techniques for detecting anomalies in the data of users and products, which give the accuracy of 80 per cent approximately. The integration with the weight selection model is also proved to be able to detect more than 80 per cent of the existing fraudulent ones while being careful not to accidentally include ones which are not, especially when the proportion of frauds is high.Originality/valueWith the rapid development of e-commerce fields, fraud detection on their data, as well as in Web crawling systems is new and necessary for research. This paper contributes a novel approach in crawling systems data authentication problem which has not been studied much.
External and internal determinants of performances of Shariah and non-Shariah compliant firms
Authors: Ho Catherine S.F. , Mohd-Raff Nor Erna Nabila 
Published: June 2019

Purpose
This study aims to provide comprehensive models that investigate the combination of both external fundamentals and internal characteristics on firm performance and if there is any difference between Shariah and non-Shariah compliant firms. The objective of this paper therefore is to analyze the significant relation between external fundamentals, internal characteristics and firm performance.

Design/methodology/approach
Panel data regression analyses are applied to determine significant results. It helps to control for unobserved factors of firm heterogeneity, which may result in spurious regression.

Findings
Most internal firm characteristics are found to be significant, but the same cannot be said for external fundamentals. Firm size is found to be very significant in driving both sets of firm performances. Financial distress in term of higher level of leverage is found to be a negative driver of non-Shariah-compliant firms’ performance in terms of return on asset but not for Shariah firms consistent with Islamic finance understanding. Shariah-compliant firms with higher liquidity tend to perform much better than less liquid firms, but the same is not found for non-Shariah-compliant ones.

Research limitations/implications
This study is limited to the industrial production sector and compares both Shariah and non-Shariah compliant firms.

Practical implications
This study adds new findings to clarify the roles of external macroeconomic fundamentals and internal characteristics determinants on firm performance. Findings from this study combine relevant information on different sets of determinants on firm performance and produce empirical evidence beneficial to both sets of Shariah and non-Shariah compliant firms in the industry.

Originality/value
This paper fulfills the need for firms to understand the external and internal environment for continuous survival and performance. It is therefore important for firms to recognize the possible factors which may influence their performance and mechanisms to sustain their performance for long-term survival.
Between cost and value
Authors: Buallay Amina 
Published: June 2019

PurposeThere are wide debates about the costs and benefits of sustainability reporting. The purpose of this paper is to investigate the relationship between sustainability reporting and a firm’s financial, operational and market performance in order to determine when sustainability reporting benefits a firm and when it adds cost.Design/methodology/approachThis study examined 342 financial institutions within the 20 countries that top the list of achievers of sustainable development goals for the 10 years 2007 through 2016, for a total of 3,420 observations. The independent variable is the environmental, social and governance (ESG) score; the dependent variables are performance indicators (return on assets, return on equity and Tobin’sQ). Two types of control variables are used in this study: firm level and country level.FindingsThe findings deduced from the empirical results demonstrate that, on the one hand, ESG positively affects market performance, which supports value creation theory. On the other hand, ESG negatively affects financial and operational performance, which supports cost-of-capital reduction theory.Research limitations/implicationsThis study aims to find how sustainable disclosure can and does play a role in contributing towards performance of financial institutions to eventually achieve country’s sustainable development goals.Practical implicationsThe study provides insights into the effect of sustainability reporting on different perspectives of business performance, which might be utilised by financial institutions to re-arrange their disclosure policy to be aligned with their strategy.Originality/valueThis study sheds light on the rare prior studies that relate sustainability reporting to indicators of business performance (operational, financial and market).
Personality traits and investor sentiment
Authors: Baker H. Kent , Kumar Satish , Goyal Nisha 
Published: June 2019

Purpose
This paper examines the relation between the Big Five model of personality traits and behavioral biases (overconfidence, disposition effect, anchoring, representativeness, metal accounting, emotional bias and herding) of Indian individual investors when making investment decisions.

Design/methodology/approach
The authors use a structured questionnaire to obtain responses from 515 stock investors in India between August 2016 and January 2017. Based on components identified through factor analysis, the authors use structural equation modeling to examine the effect of specific personality traits.

Findings
The findings indicate a significant association between the traits of neuroticism, extroversion and conscientiousness as well as behavioral biases of individual investors. Openness has a significant relation with only mental accounting and the agreeableness trait has no relation with the behavioral biases examined.

Research limitations/implications
The findings imply that understanding investor personality differences and investment psychology can help financial advisors and wealth managers modify products and services to better suit client needs.

Originality/value
To the best of the authors’ knowledge, no previous study has examined the impact of the Big Five model of personality traits on various behavioral biases among Indian investors.
Riffing Off Kevin Cox: Thinking through Comparison
Authors: Cochrane Allan 
Published: June 2019

AbstractThe question of comparison is one that haunts contemporary urban and regional studies—the need for it is taken for granted, but what it is, how to do it and what it can teach us remain matters of contention. In 2016 Kevin Cox published a book that brought some of these issues to the fore, challenging the ways in which US models have tended to dominate and (with the help of reflections on the experience of Western Europe) highlighting the extent of what he called the American exception. In this intervention four authors from different perspectives and located in different geographies deliver not a review or critique of the text but a series of responses, riffing off Cox to generate ways of thinking about comparison as well as offering alternative ways of approaching some of the issues with which he grapples, reflecting on particular national experiences while setting out to place them comparatively, and drawing wider conclusions while posing new questions, to which Kevin Cox in turn responds.

Taking Complex Systems Seriously: Visualizing and Modeling the Dynamics of Sustainable Peace
Authors: Coleman Peter T. , Liebovitch Larry S. , Fisher Joshua 
Published: June 2019

AbstractThe recent United Nation Secretary General's report on sustaining peace speaks to an urgent crisis of complexity in global affairs, where a wide assortment of nonstate actors wields more political power than ever before. In this context, the international community's traditional ways of forecasting, planning, policymaking, and assessing impact are becoming rapidly obsolete. In response, policymakers are calling for more holistic or systemic approaches to peace and development. Unfortunately, these proposed changes are merely ‘systems light’, essentially a metaphorical characterization of peace systems where their component parts are seen as interconnected and complicated. This form of systems thinking is insufficiently informed by more sophisticated methods from complexity science. This article will illustrate how two methods derived from complexity science, causal loop diagramming and mathematical modeling, can help us understand the properties and dynamics of intervention in complex peace systems. Causal loop diagrams help us to identify the peace factors and the connections between them. Mathematical modeling helps us determine the quantitative results of the interactions between all the peace factors. Using these methods together can lead to new insights for peacebuilding and for mitigating the unintended consequences of well intended policies.
Fluid balance after continuous renal replacement therapy initiation and outcome in paediatric multiple organ failure
Authors: Andersson Andreas , Norberg Åke , Broman Lars Mikael , Mårtensson Johan , Fläring Urban 
Published: June 2019

BackgroundPatients with multiple organ failure (MOF) often receive large amounts of resuscitation fluid, making them at high risk of fluid overload (FO). Our main objective was to investigate if the ability to achieve a negative fluid balance during the first 3 continuous renal replacement therapy (CRRT) days was associated with mortality in children with MOF.MethodsRetrospective cohort study in a tertiary multidisciplinary academic paediatric hospital. The study included 63 patients (age 0‐18 years) with 3 or more failing organs receiving CRRT due to acute kidney injury and/or fluid overload.ResultsThe median age was 4 months, and PICU mortality was 29%. Survivors had significantly lower degree of FO at CRRT initiation, (median 15% (Interquartile range 9‐22)) than non‐survivors (24% (17%‐37%), P = 0.002). On PICU admission, PIM‐3 score was significantly higher in non‐survivors (P = 0.01), but at CRRT initiation there was no difference in PELOD‐2 score (P = 0.98). Mortality in patients achieving a cumulative net negative fluid balance during the first 3 days after CRRT initiation was 12%, compared to 86% in those not achieving this (P < 0.0001). In multivariate analysis, the inability to achieve a net negative fluid balance during 3 days after CRRT initiation (P < 0.0001) and FO >20% at CRRT initiation (P = 0.0019) remained associated with mortality.ConclusionOur results suggest that early fluid removal is associated with improved patient outcome in critically ill children receiving CRRT, and that prompt measures should be taken to prevent fluid overload in critical illness. These results need to be verified in further, prospective studies.

Authors: Zamani Mohammad , Alizadeh‐Tabari Shaghayegh , Zamani Vahid 
Published: June 2019

SummaryBackgroundIrritable bowel syndrome (IBS) is a common and potential disabling functional gastrointestinal disorder. Studies have revealed a possible association between IBS and psychological problems, such as anxiety and depression. Existing systematic reviews have addressed only the levels of anxiety or depression in patients with IBS.AimTo investigate systematically the prevalence of anxiety or depression in IBS patientsMethodsA literature search was conducted using the related keywords from the bibliographic databases of Embase, PubMed, Scopus, Web of Science and POPLINE published until 1 January 2019 with no language restriction. Studies reporting the prevalence of anxiety/depressive symptoms/disorders in adult (≥15 years) IBS patients were evaluated. The pooled prevalence, odds ratio (OR) and 95% CI were calculated using stata software.ResultsA total of 14 926 articles were initially screened, and finally 73 papers were included. The prevalence rates of anxiety symptoms and disorders in IBS patients were 39.1% (95% CI: 32.4‐45.8) and 23% (95% CI: 17.2‐28.8) respectively. The ORs for anxiety symptoms and disorders in IBS patients compared with healthy subjects were 3.11 (95% CI: 2.43‐3.98) and 2.52 (95% CI: 1.99‐3.20) respectively. The prevalence estimates of depressive symptoms and disorders in IBS patients were 28.8% (95% CI: 23.6‐34) and 23.3% (95% CI: 17.2‐29.4) respectively. The ORs for depressive symptoms and disorders in IBS patients compared to healthy subjects were 3.04 (95% CI: 2.37‐3.91) and 2.72 (95% CI: 2.45‐3.02) respectively.ConclusionPatients with IBS have a three‐fold increased odds of either anxiety or depression, compared to healthy subjects.

Published: June 2019

SummaryWe report the off‐label use of bortezomib combined with dexamethasone in eight adults with severe and multi‐refractory warm auto‐immune haemolytic anaemia (wAIHA). After six cycles of induction therapy, 6 of the 8 patients achieved response (3 complete response, 3 response). Response was obtained after a median of 2 (1–4) cycles. After a median follow‐up of 14 (6–36) months, six patients maintained a response (bortezomib/dexamethasone maintenance, n = 4); five patients experienced at least one moderate adverse event, including peripheral neuropathy (n = 2). These results suggest that bortezomib/dexamethasone combination is a promising approach with acceptable toxicity for treating severe refractory wAIHA in adults.
Information, accountability and perceptions of public sector programme success: A conjoint experiment among bureaucrats in Africa
Authors: Harris Adam S. , Seim Brigitte , Sigman Rachel 
Published: June 2019

AbstractMotivationWhether public sector organizations implement programmes successfully is a key concern of development scholars and practitioners across the world. While many studies purport the existence of a link between social accountability and public sector performance, this relationship has been difficult to study empirically.PurposeThis article examines whether bureaucrats expect public sector programmes with information‐sharing mechanisms, including visibility, transparency and collaboration, to be successful in terms of effectiveness and limiting corruption.Approach and MethodsThe article uses a conjoint survey experiment administered to thousands of bureaucrats across three African countries: Ghana, Malawi and Uganda. By asking bureaucrats—those with insider knowledge of government programme operations—about two hypothetical programmes with randomly assigned characteristics, we examine whether bureaucrats associate opportunities for monitoring by citizens and civil society groups with the success of public sector programmes.FindingsAcross diverse country and organizational contexts, bureaucrats consistently attribute high probabilities of success to programmes that are visible to the public, transparent in their implementation, and open to collaboration with civil society. Moreover, the inclusion of any one of these information‐sharing mechanisms can independently increase the perceived likelihood of success. The findings hold across institutional contexts and diverse subgroups of bureaucrats surveyed.Policy ImplicationsTo promote success in the implementation of public sector development programmes, officials should look for ways to increase the visibility of their programmes, set requirements for frequent public updates on programme progress, and build in opportunities for outside groups to collaborate.

AimsLymphovascular space invasion (LVSI) in endometrial cancer (EC) is an important prognostic variable impacting on a patient's individual recurrence risk and adjuvant treatment recommendations. Recent work has shown that grading the extent of LVSI further improves its prognostic strength in patients with stage I endometrioid EC. Despite this, there is little information on the reproducibility of LVSI assessment in EC. Therefore, we designed a study to evaluate interobserver agreement in discriminating true LVSI from LVSI mimics (Phase I) and reproducibility of grading extent of LVSI (Phase II).Methods and resultsScanned haematoxylin and eosin (H&E) slides of endometrioid EC (EEC) with a predefined possible LVSI focus were hosted on a website and assessed by a panel of six European gynaecological pathologists. In Phase I, 48 H&E slides were included for LVSI assessment and in Phase II, 42 H&E slides for LVSI grading. Each observer was instructed to apply the criteria for LVSI used in daily practice. The degree of agreement was measured using the two‐way absolute agreement average‐measures intraclass correlation coefficient (ICC). Reproducibility of LVSI assessment (ICC = 0.64, P < 0.001) and LVSI grading (ICC = 0.62, P < 0.001) in EEC was substantial among the observers.ConclusionsGiven the good reproducibility of LVSI, this study further supports the important role of LVSI in decision algorithms for adjuvant treatment.
The lasting biological signature of Pliocene tectonics: Reviewing the re‐routing of Australia's largest river drainage system
Authors: Waters Jonathan M. , Burridge Christopher P. , Craw Dave 
Published: June 2019

AbstractAimBiological diversification can be substantially influenced by earth history. The links between biological and geological processes can be particularly tight for obligate freshwater biota. Here, we test for such links with respect to Pliocene shifts in drainage geometry of one of the Australia's largest river systems.LocationMajor rivers of south‐eastern Australia.TaxonFreshwater‐limited fishes and crayfish.MethodsWe synthesize recently published geological and freshwater phylogeographic data to elucidate the evolutionary history of south‐eastern Australia's major river drainages and their biotas.ResultsRecent data demonstrate how a major Pliocene drainage rearrangement event in the lower Murray‐Darling basin led to the evolution of a distinctive and “marooned” phylogeographic assemblage in the Glenelg and Wimmera drainages.Main conclusionsBiological data from southern Australia illuminate the region's geological history, and vice versa. Our study highlights the persisting evolutionary effects of a major Pliocene drainage rearrangement. The lasting geological and biological preservation of such an ancient tectonic event is apparently facilitated by Australia's uniquely stable geological setting.
Use of Data Mining Methods to Detect Test Fraud
Authors: Man Kaiwen , Harring Jeffrey R. , Sinharay Sandip 
Published: June 2019

AbstractData mining methods have drawn considerable attention across diverse scientific fields. However, few applications could be found in the areas of psychological and educational measurement, and particularly pertinent to this article, in test security research. In this study, various data mining methods for detecting cheating behaviors on large‐scale assessments are explored as an alternative to the traditional methods including person‐fit statistics and similarity analysis. A common data set from the Handbook of Quantitative Methods for Detecting Cheating on Tests (Cizek & Wollack) was used for comparing the performance of the different methods. The results indicated that the use of data mining methods may combine multiple sources of information about test takers' performance, which may lead to higher detection rate over traditional item response and response time methods. Several recommendations, all based on our findings, are provided to practitioners.
