The psychological contract of international volunteers: an exploratory study
Authors: Barrett Mary , Cox Anne , Woodward Blake 
Published: May 2017

PurposeThe purpose of this paper is to investigate the psychological contracts (PCs) of international volunteers (IVs) in international aid and development organizations (IADS). Specifically, it explores four questions: how IVs form PCs; what the content of these PCs is; how IVs’ PCs are maintained; and how they are fulfilled or breached.Design/methodology/approachThe study used an inductive analysis of qualitative data: interviews with 27 IVs from a range of IADS.FindingsThe findings take the form of research propositions: RP1: IVs’ PCs, like those of domestic volunteers, include relational, transactional and, especially, values-based elements, but the balance of these is influenced by their values-based PC; the self-directed way IVs join their organizations; and reliance on peers rather than the organization’s management hierarchy. RP2: the PCs of IVs working for faith-based organizations have an additional element: spiritual support. RP3: the values-based PC means many transactional elements can be “adjusted away”, making it difficult to breach these PCs. RP4: experienced volunteers have very minimal PCs, but are more likely than inexperienced volunteers to expect basic safety and adequately skilled colleagues.Research limitations/implicationsThe authors suggest areas of new inquiry and specific ways each research proposition could be tested empirically.Practical implicationsTo alleviate IVs’ expatriation and repatriation adjustment problems, international aid organizations could facilitate the ways IVs already help each other. This would also help fulfill IVs’ PCs.Originality/valueIVs are a growing but underexplored group and aspects of their PCs may be unique.
Capability transformation through acquisitions
Authors: Goussevskaia Anna , Arruda Carlos , Lótfi Samir 
Published: May 2017

PurposeFirms across many industries use acquisitions as a vehicle for renewing their capabilities. Many such acquisitions fail to achieve their goals, mainly because of the trade-offs involved in managing the post-acquisition integration process. The acquisition integration process not only is an important phenomenon by itself but also offers a unique opportunity to gain insight into how firms transform their capabilities more generally. Recent strategic management literature has begun to recognize the importance of incorporating individual-level cognitive, motivational and behavioral mechanisms into firm-level explanations, although empirical studies within this vein have been scarce.Design/methodology/approachThis longitudinal inductive study traces the process of capability transformation in an acquisition of a medium-size entrepreneurial firm by a larger corporation.FindingsThe authors found that capability transformation involved a continuous interplay of knowledge leveraging and interest alignment mechanisms, converging around a set of practices that were considered critical for the capability. Only after firms achieved an agreement about this set of practices that knowledge leveraging efforts translated into actual performance.Originality/valueThe study contributes to the literature on competitive advantage by developing a better link between the potential advantage derived from the availability of knowledge-based resources and the translation of this availability into actual firm performance. This study also advances knowledge on managing post-acquisition integration process by demonstrating which managerial skills and actions contribute to the integration capability.

Published: May 2017

PurposeThe shopping center (SC) industry in emerging countries has grown fast over the past decade; however, recently, it is showing signs of slowing down. Nevertheless, some SC-companies perform well. As those firms operate in alliance networks, relational opportunities and risks should be considered in their strategic analyses. Although there is a significant amount of research on SC from a marketing perspective, there is a dearth of research on strategic alliances from an SC management perspective. This paper aims at answering the following question: How do characteristics of the alliance networks of leading SC-companies contribute to their success by mitigating the structural threats the SC-industry in Brazil is facing?DesignThe case study method was adopted for analyzing two leading Brazilian SC-companies. Several data sources were used to allow for data triangulation. The lack of literature on strategic alliances and the SC-industry, as well as the research’s exploratory nature, justified this choice.FindingsThe research made evident that the SC-companies’ alliance network characteristics not only mitigate some of the structural industry threats but also enhance opportunities. It illustrated how firms can conduct a strategic analysis from a network perspective with the right tools. It also made evident how much more accurate the results of a comprehensive relational analysis are compared with traditional analyses that do not consider the strategic implications of relational factors.Practical implicationsThe research contributed to SC management by highlighting the importance of taking into account the network characteristics of their relationships with key partners and of considering these as alliances and not merely contractual arrangements.Originality/valueThere is a dearth of research on the strategic implications of alliances of firms that own and manage a portfolio of SCs, as well as of their relationships with other actors in the industry, such as retailers and real estate owners, from a network perspective.

Published: May 2017

PurposeThe purpose of this paper is to examine the influence of structural empowerment, psychological empowerment and intrinsic motivation on perceived customer satisfaction in contact centers.Design/methodology/approachA questionnaire was conducted among 703 employees of a contact center. Data analysis was based on structural equation modeling.FindingsStructural empowerment results in higher levels of perceived customer satisfaction through psychological empowerment and intrinsic motivation. Furthermore, structural empowerment effect on psychological empowerment is mediated by intrinsic motivation.Practical implicationsPrevious predictions regarding counterproductive impact of empowerment in a low-service heterogeneity sector, such as contact center are challenged and a transformative message is disclosed in what concerns human resource management (HRM) in contact centers.Originality/valueThe research provides valuable insights for both scholars and practitioners regarding the process through which employees’ psychological empowerment and intrinsic motivation improves customer satisfaction in the context of contact centers.
Individual versus pseudo‐repeatability in behaviour: Lessons from translocation experiments in a wild insect
Authors: Niemelä Petri T. , Dingemanse Niels J. 
Published: May 2017

Abstract

Repeatability represents a key parameter in ecological and evolutionary research. Repeatability is underpinned by developmental plasticity and genetic variation but may become biased upwards by repeatable differences in environments to which individuals respond plastically. The extent of upward bias caused by the latter mechanism (causing “pseudo‐repeatability”) is important yet rarely investigated in ecological research.

We repeatedly assayed a key behaviour (flight initiation distance) affecting longevity in a wild cricket population (Gryllus campestris). We used naturally moving, translocated and forced‐stationary individuals to study bias in repeatability caused by spatial variability in environmental conditions.

Our experiments acknowledged that translocations might themselves bias repeatability estimates if animals respond to handling procedures (a necessary component of translocations). Individuals were, therefore, either (i) repeatedly translocated and assayed or (ii) assayed at multiple burrows as part of natural movements. This enabled estimation of behavioural variance attributable to individual, burrow and residual components within each treatment; comparison across treatments addressed whether translocations caused bias. We also calculated repeatability for individuals that were forced to be stationary to investigate whether this led to upward bias of repeatability.

For adult crickets, individual explained 17.8% versus 17.2%, and burrow 8.7% versus 10.3%, of the behavioural variance in translocated versus natural‐movement treatments. Repeatability for forced‐stationary adults was 31.1%, thereby demonstrating experimentally that certain study designs bias repeatability upwards. For translocated juveniles, individual explained 10.0% and burrow 6.0% of the variance, while in the natural‐movement treatment, those components could not be separated as juveniles do not switch burrows. Translocations did not lead to detectable biases in behavioural mean or variance.

Repeatability was not biased for adults subjected to the natural‐movement treatment because individuals were assayed under many different environments, facilitating the separation of individual from burrow effects. Upward bias would have occurred with less optimal sampling schemes: if individuals had been assayed repeatedly at the same burrow. We, therefore, recommend that translocation experiments are more commonly applied, particularly in stationary species, to ensure the unbiased estimation of repeatability.

AbstractAimSarcoidosis is a multisystem granulomatous disease. This condition has a documented association with the diagnosis of melanoma and can be induced in melanoma patients receiving anti‐neoplastic therapy. We evaluated a case series of melanoma patients who developed immunotherapy‐induced sarcoidosis.MethodsThree patients with melanoma (n = 1 resected Stage III, n = 2 metastatic) treated with anti‐programmed cell death (PD)‐1 antibody therapy at two institutions developed biopsy‐proven sarcoidosis. We used mass cytometry to determine expression of the relevant chemokine receptors (CR) by peripheral blood mononuclear cells for two of the three patients who developed sarcoidosis and 13 melanoma patients who did not. Blood samples were collected before receiving PD‐1 checkpoint inhibitor therapy.ResultsImmunophenotypic analysis demonstrated abnormally high numbers of circulating Th17.1 (CCR6+CCR4−CXCR3+CCR10−) cells prior to commencing PD‐1 checkpoint inhibitor therapy in five of 15 melanoma patients, including both the patients who developed sarcoidosis during the course of therapy.ConclusionOur findings support prior literature implicating Th17.1 cells in the pathogenesis of sarcoidosis. However, we demonstrate these findings in patients with melanoma prior to administration of checkpoint therapy and before the onset of clinically symptomatic sarcoidosis. The identification of elevated Th17.1 cells in melanoma patients who have not developed sarcoidosis may reflect the established association between melanoma and sarcoidosis. With some patients receiving these agents over a prolonged period, the clinical course of immunotherapy‐induced sarcoidosis is uncertain.

Authors: Hamoudi Hassan , Christensen Ulrik Correll , La Cour Morten 
Published: May 2017

AbstractPurposeTo assess the impact of sequential and combined surgery [cataract surgery and 23‐gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics.MethodsPhakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group). Eyes were examined at baseline, 1 month after each surgery, and at 3 and 12 months follow‐up. Corneal endothelium cell density (CED) was assessed with non‐contact specular microscopy. Pachymetry [central cornea thickness (CCT)], keratometry and cornea volume (CV) were measured with Pentacam Scheimpflug camera. Primary outcome was change in CED after 12 months; secondary outcomes were changes in CCT and CV after 12 months.ResultsSixty‐two eyes were enrolled and allocated to the three groups. The mean preoperative CED was 2776, 2794 and 2653 cells/mm2, which decreased significantly at 12 months by 15.3, 20.0 and 19.3% in the CAT, VIT and COMBI group. There was no significant difference in percentage cell loss between the groups at final follow‐up. The CED decreased significantly after cataract surgery, but was unaffected by PPV. Central cornea thickness (CCT) increased by 10 μm (p = 0.005) and CV by 1.38 mm3 (2.3%, p < 0.001) in the COMBI group. There were no significant differences in CCT or CV between the groups at final follow‐up.ConclusionCombined and sequential surgery in ERM leads to a small decrease in CED. Performing cataract surgery before, after or in combination with vitrectomy did not make any significant difference with respect to final CED, CCT or CV.
Functional Multiple Indicators, Multiple Causes Measurement Error Models

Published: May 2017

Summary
Objective measures of oxygen consumption and carbon dioxide production by mammals are used to predict their energy expenditure. Since energy expenditure is not directly observable, it can be viewed as a latent construct with multiple physical indirect measures such as respiratory quotient, volumetric oxygen consumption, and volumetric carbon dioxide production. Metabolic rate is defined as the rate at which metabolism occurs in the body. Metabolic rate is also not directly observable. However, heat is produced as a result of metabolic processes within the body. Therefore, metabolic rate can be approximated by heat production plus some errors. While energy expenditure and metabolic rates are correlated, they are not equivalent. Energy expenditure results from physical function, while metabolism can occur within the body without the occurrence of physical activities. In this manuscript, we present a novel approach for studying the relationship between metabolic rate and indicators of energy expenditure. We do so by extending our previous work on MIMIC ME models to allow responses that are sparsely observed functional data, defining the sparse functional multiple indicators, multiple cause measurement error (FMIMIC ME) models. The mean curves in our proposed methodology are modeled using basis splines. A novel approach for estimating the variance of the classical measurement error based on functional principal components is presented. The model parameters are estimated using the EM algorithm and a discussion of the model's identifiability is provided. We show that the defined model is not a trivial extension of longitudinal or functional data methods, due to the presence of the latent construct. Results from its application to data collected on Zucker diabetic fatty rats are provided. Simulation results investigating the properties of our approach are also presented.
Integrative Analysis of Transcriptomic and Metabolomic Data via Sparse Canonical Correlation Analysis with Incorporation of Biological Information
Authors: Safo Sandra E. , Li Shuzhao , Long Qi 
Published: May 2017

Summary
Integrative analysis of high dimensional omics data is becoming increasingly popular. At the same time, incorporating known functional relationships among variables in analysis of omics data has been shown to help elucidate underlying mechanisms for complex diseases. In this article, our goal is to assess association between transcriptomic and metabolomic data from a Predictive Health Institute (PHI) study that includes healthy adults at a high risk of developing cardiovascular diseases. Adopting a strategy that is both data-driven and knowledge-based, we develop statistical methods for sparse canonical correlation analysis (CCA) with incorporation of known biological information. Our proposed methods use prior network structural information among genes and among metabolites to guide selection of relevant genes and metabolites in sparse CCA, providing insight on the molecular underpinning of cardiovascular disease. Our simulations demonstrate that the structured sparse CCA methods outperform several existing sparse CCA methods in selecting relevant genes and metabolites when structural information is informative and are robust to mis-specified structural information. Our analysis of the PHI study reveals that a number of gene and metabolic pathways including some known to be associated with cardiovascular diseases are enriched in the set of genes and metabolites selected by our proposed approach.

Published: May 2017

SummaryThere is a need for well‐developed and validated questionnaires to measure patient reported outcomes. The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is such a validated instrument measuring disease‐specific health‐related quality of life in hand eczema patients. A re‐validation of measurement properties is required before an instrument is used in a new population. With the objective of arriving at a guideline for translation and national validation of the QOLHEQ, we have developed the design of a reference study on how to adequately assess measurement properties of the QOLHEQ based on interdisciplinary discussions and current standards. We present a step‐by‐step guideline to assess translation (including cross‐cultural adaptation), scale structure, validity, reproducibility, responsiveness, and interpretability. We describe which outcomes should be reported for each measurement property, and give advice on how to calculate these. It is also specified which sample size is needed, how to deal with missing data, and which cutoff values should be applied for the measurement properties assessed during the validation process. In conclusion, this guideline, presenting a reference validation study for the QOLHEQ, creates the possibility to harmonize the national validation of the various language versions of the QOLHEQ.

AbstractAimSurgical technique constantly evolves in response to the pressure of progress. Ileal pouch anal anastomosis (IPAA) is a good example. We analysed the effect of changes in practice on the technique of IPAA and its outcomes.MethodPatients undergoing primary IPAA at this institution were divided into three groups by date of the IPAA: those operated from 1983 to 1993, from 1994 to 2004 and from 2005 to 2015. Demographics, patient comorbidity, surgical techniques, postoperative outcomes, pouch function and quality of life were analysed.ResultsIn all, 4525 patients had a primary IPAA. With each decade, increasing numbers of surgeons were involved (decade I, 8; II, 16; III, 31), patients tended to be sicker (higher American Society of Anesthesiologists score) and three‐staged pouches became more common. After an initial popularity of the S pouch, J pouches became dominant and a mucosectomy rate of 12% was standard. The laparoscopic technique blossomed in the last decade. 90‐day postoperative morbidity by decade was 38.3% vs 50% vs 48% (P < 0.0001), but late morbidity decreased from 74.2% through 67.1% to 30% (P < 0.0001). Functional results improved, but quality of life scores did not. Pouch survival rate at 10 years was maintained (94% vs 95.2% vs 95.2%; P = 0.06).ConclusionIPAA is still evolving. Despite new generations of surgeons, a more accurate diagnosis, appropriate staging and the laparoscopic technique have made IPAA a safer, more effective and enduring operation.
Monetary and Multidimensional Child Poverty: A Contradiction in Terms?
Authors: Roelen Keetie 
Published: May 2017

ABSTRACTAlthough the multidimensional nature of poverty is widely recognized, the extent to which monetary measures can serve as a proxy for non‐monetary measures remains unresolved. This is of particular concern for children given their dependence on others for fulfilment of basic needs and assumptions about intra‐household distribution that underpin monetary measures. This article adopts an innovative mixed‐methods approach to investigate child poverty overlap and mismatch in the low‐ and middle‐income countries of Ethiopia and Vietnam using secondary longitudinal survey data and primary qualitative data from adults and children. Findings indicate that monetary and multidimensional poverty are distinct constructs that are linked, but cannot serve as a proxy for one another. While the degree of dissonance depends on the types of indicators under consideration, poverty mismatch persists regardless of time, place and multidimensional measure under consideration.

ABSTRACTThis article critically analyses the use of psychological and behavioural knowledge in development policy and practice with reference to the World Development Report 2015. It examines the main proposition of the WDR 2015, highlighting the behavioural change framework and policy techniques promoted in the report. The shifts that have taken place in development policy are reviewed from a governmentality perspective which offers a critical view on the psychological and behavioural focus in contemporary development policy. The article focuses specifically on the behavioural techniques the WDR 2015 promotes to show how a certain kind of subjectivity is advanced which not only homogenizes and problematizes non‐Western knowledge systems, subjectivities and agency, but also justifies the economization of social life through development.
