Trajectory classes of job performance
Authors: Miraglia Mariella , Alessandri Guido , Borgogni Laura 
Published: July 2015

Purpose– Previous literature has recognized the variability of job performance, calling attention to the inter-individual differences in performance change. Building on Murphy’s (1989) theoretical model of performance, the purpose of this paper is to verify the existence of two distinct classes of performance, reflecting stable and increasing trends, and to investigate which personal conditions prompt the inclusion of individuals in one class rather than the other.Design/methodology/approach– Overall job performance was obtained from supervisory ratings for four consecutive years for 410 professionals of a large Italian company going through significant reorganization. Objective data were merged with employees’ organizational tenure and self-efficacy. Growth Mixture Modeling was used.Findings– Two main groups were identified: the first one started at higher levels of performance and showed a stable trajectory over time (stable class); the second group started at lower levels and reported an increasing trajectory (increasing class). Employees’ with stronger efficacy beliefs and lower tenure were more likely to belong to the stable class.Originality/value– Through a powerful longitudinal database, the nature, the structure and the inter-individual differences in job performance over time are clarified. The study extends Murphy’s (1989) model, showing how transition stages in job performance may occur also as a result of organizational transformation. Moreover, it demonstrates the essential role of self-efficacy in maintaining high performance levels over time.
Antecedents of perceived overqualification: a three-wave study
Authors: Guerrero Laura , Hatala John-Paul 
Published: July 2015

Purpose
– The purpose of this paper is to investigate the role of job search on perceived overqualification by applying the theory of planned behavior and including financial need and openness to experience as moderators.

Design/methodology/approach
– Three questionnaires were given at weeks 1, 8 and 12 to 436 practice firm participants. A total of 119 completed all three questionnaires. The authors used partial least squares to analyze the data.

Findings
– Job search self-efficacy was positively related to job search intentions and to outcome expectations. Job search intentions were positively related to job search intensity. Financial need acted as a moderator of the relationship between job search intensity and perceived overqualification such that for those with high-financial need higher levels of job search intensity resulted in higher perceived overqualification.

Research limitations/implications
– The authors found little support for the theory of planned behavior in the model. The authors found strong support for the role of job search self-efficacy and job search intentions. The use of a three-wave design resulted in a relatively low sample size and the use of the practice firm reduces the generalizability of the findings.

Practical implications
– The results suggest that increasing job search self-efficacy and job search intentions while managing the anticipations of job seekers is likely to yield better job search outcomes.

Originality/value
– This study investigates the role of job search on perceived overqualification. Findings suggest that malleable attitudes during job search such as job search self-efficacy, job search intentions, and anticipations are likely to impact perceived overqualification.

Authors: Al-Amri Khalid 
Published: July 2015

Purpose
– The purpose of this paper is to analyze the performance of the Takaful insurance firms in the Gulf Cooperation Council (GCC) countries and do a relative analysis for its different units.

Design/methodology/approach
– This paper analyzes the technical, pure technical, cost and allocative efficiency of Takaful firms in the GCC countries using data envelopment analysis (DEA) methodology.

Findings
– The Takaful insurance industry in GCC is highly technical and pure technical efficient. However, it is moderately cost efficient, and there is a large opportunity for improvement. UAE and Qatar score the highest technical efficiency, while Saudi Arabia and UAE are the most cost efficient among the GCC countries.

Originality/value
– The primary contribution of this paper is to provide the first DEA analysis of the Takaful industry in the GCC countries. To the best of the author’s knowledge, this is the first study on the Takaful insurance industry that uses different types of efficiency measures, namely technical, pure technical, allocative and cost efficiency, in the GCC countries. This paper also contributes in the literature of the inputs and outputs selection for the Takaful insurance efficiency calculation.
Socially responsible stocks: a boon for investors in India
Authors: Tripathi Vanita , Bhandari Varun 
Published: July 2015

Purpose
– The purpose of this paper is to empirically examine the performance of socially responsible stocks portfolio vis-à-vis portfolios of general companies in the Indian stock market.

Design/methodology/approach
– The study has used absolute rate of return as well as various risk adjusted measures like Sharpe ratio, Treynor ratio, Jensen’s α, Information ratio, Fama’s decomposition measure and dummy regression model to evaluate the performance of various portfolios.

Findings
– Socially responsible stocks portfolios are found to have lower relative risk despite having higher systematic risk. Further the authors find that during crisis and post-crisis period, socially responsible stocks portfolio generated significantly higher return as compared to other portfolios in the Indian stock market. Environmental, social and governance (ESG) Index and GREENEX Index provided positive net selectivity returns in all the three sub periods, especially during crisis period. GREENEX and ESG outperformed NIFTY and SENSEX even on net selectivity basis. This indicates that the compromise made with respect to diversification by investing in socially responsible stocks portfolios was well rewarded in terms of higher returns in Indian context.

Practical implications
– The findings lend support to the case of socially responsible investing (SRI) in India and are relevant for companies, regulators, policy makers and investors at large. Mutual funds and other investment funds should launch schemes which invest in socially responsible stocks so as to provide the benefits of SRI even to small investors in India.

Originality/value
– The study contributes to the related literature by analysing the performance of socially responsible stocks portfolios in Indian stock market which is one of the emerging markets.
Infrastructure and core quality practices in Indian manufacturing organizations
Authors: Patyal Vishal Singh , Koilakuntla Maddulety 
Published: July 2015

Purpose– The purpose of this paper is to develop and validate a scale for infrastructure and core practices, including total quality management (TQM) and Six Sigma practices, in the Indian manufacturing organizations.Design/methodology/approach– In this study, a psychometric systematic scale development procedure has been adopted and executed, which includes three phases. Phase 1 includes item generation and selection through expert opinion. In Phase 2, scale refinement using item analysis, exploratory factor analysis, confirmatory factor analysis (CFA), and convergent and discriminant validity have been carried out. Finally, in Phase 3, scale validation through the replication of CFA and nomological validity assessment has been conducted. Also, a higher order measurement and structural model has been used to assess predictive validity of infrastructure and core practices.Findings– The findings of the empirical study resulted in a 45-item scale that measures Infrastructure practices (top management commitment, workforce management, supplier relationship, customer relationship management, Six Sigma role structure) and core practices (process management, product/service design, quality information and analysis, Six Sigma metric, Six Sigma structure), considering both TQM and Six Sigma practices. Also, the higher order predictive validity assessment model suggested that core practices have a higher impact on quality performance than infrastructure practices.Research limitations/implications– This study considered TQM and Six Sigma practices for defining infrastructure and core practices. However, future studies may include other quality tools in infrastructure and core quality practices such as Lean, Kaizen, and others in the measurement model to get more concrete results.Practical implications– This reliable and valid scale will help managers measure the level of QM in order to enhance business performance.Originality/value– This study symbolizes a first-time attempt for developing a validated tool to measure infrastructure and core practices in the Indian manufacturing organizations.

Authors: Ganesh M. P. , Gupta Meenakshi 
Published: July 2015

Purpose– The purpose of this paper is to understand the impact of procedural justice on team members’ commitment and the role of task routineness and participatory safety in this relationship.Design/methodology/approach– Survey method was used to collect data from 177 respondents from 33 software development teams. Participatory Safety Scale from Anderson and West’s Team Climate Inventory, Colquitt’s Procedural Justice Scale, a modified version of Mowdayet al.’s Organizational Commitment Scale and Daft and Macintosh’s Task Routineness Scale were used to measure the variables studied. Regression analysis was used to test the main, mediating and moderating effects.Findings– Results showed a significant positive impact of procedural justice perception on participatory safety dimensions and team commitment. Task routineness did not show any significant moderation effect. Perception of participatory safety had a partial mediation effect.Research limitations/implications– A relatively smaller sample size, purposive sampling technique and absence of relevant control variables are the key limitations of this study.Practical implications– The findings will provide managers insights on designing the team tasks and procedures to nurture participatory safety and commitment in teams.Originality/value– The study is unique in terms of selection of variables, design (moderation and mediating effects) and the context (software development teams). The study provides a holistic picture of team dynamics by studying variables related to procedures, task and psychological states of the individual.
Emergency relief supply chain design and trade-off analysis
Authors: Hong Jae-Dong , Jeong Ki-Young , Feng Keli 
Published: July 2015

Purpose
– Emergency relief supply chain (ERSC) design is an important strategic decision that significantly affects the overall performance of emergency management activities. The performance of an ERSC can be measured by several performance measures some of which may conflict with each other. The purpose of this paper is to propose an ERSC design framework by simultaneously taking total logistics cost (TLC), risk level, and amount of demands covered in an ERSC into consideration.

Design/methodology/approach
– The study considers TLC of an ERSC as the sum of logistics cost from distribution warehouses (DWHs) to Break of Bulbs (BOBs) and from BOBs to affected neighborhoods. The risk level of an ERSC is measured by estimating the expected number of disrupted relief items (EDI) distributed from DWHs through BOBs to neighborhoods. The covered demand (CDM) is defined as total populations that are supported in case of an emergency, the populations within the maximal coverage distance (MCD) from relief facilities. Based on these performance measures, the authors formulate a Goal Programming (GP) model to distribute emergency relief items to affected locations. Ideal values of these performance measures are decided, and the GP model seeks to minimize the weighted sum of the percentage deviations of those performance measures from the ideal values. The relationships among performance measures have been thoroughly analyzed through detailed trade-off studies under two realistic case studies by changing weights of each performance measure.

Findings
– Three performance measures are interdependent over specific values of weights. TLC and EDI have a trade-off relationship when the weight on each measure increases. TLC and CDM also have a trade-off relationship when the weight on EDI increases. However, this relationship becomes less apparent when the MCD increases. EDI and CDM also have the same trade-off relationship when the weight on TLC changes. Therefore, decision makers should thoroughly analyze these trade-off relationships when they design ERSCs. Overall, the study identified that an ERSC with higher MCD outperforms one with lower MCD in terms of TLC, EDI, and CDM.

Originality/value
– The study presents a design framework to generate more balanced ERSCs by simultaneously taking three conflicting performance measures into consideration, and demonstrated the feasibility of the framework through realistic case studies. The trade-off analysis provides useful insights and theoretical knowledge to researchers and practitioners in the discipline of emergency logistics management. The results from this study are expected to contribute to the development of more balanced ERSCs.
Reverse logistics in humanitarian operations: challenges and opportunities
Authors: Peretti Umberto , Tatham Peter , Wu Yong , Sgarbossa Fabio 
Published: July 2015

Purpose
– Whilst implementation of a broad range of reverse logistics (RL) practices is increasingly the norm within commercial supply chain management, they have had limited impact in the humanitarian logistics (HL) sector. The purpose of this paper is to analyse the challenges and opportunities for the application of RL in a HL context.

Design/methodology/approach
– Through a broad review of both the academic and practitioner literature, supplemented by informal discussions with senior humanitarian logisticians, the paper summarises the current state of RL within the HL sector before recommending ways in which practices that are increasingly found in a commercial context could be implemented.

Findings
– The findings indicate that, to date, the use of commercial RL practices is extremely limited within the HL sector, but there are a number of areas where their introduction be possible in the future.

Research limitations/implications
– Whilst the reviews of the literature were comprehensive, further and more detailed research into the RL practices (if any) undertaken by aid agencies needs to be undertaken in order that appropriate lessons and experiences can be implemented across the sector as a whole.

Practical implications
– Given the overall desire of humanitarian agencies to “do no harm” it will be increasingly important for such organisations to embrace RL practices in order to improve the sustainability of their disaster preparation and response activities.

Social implications
– In light of the generally increased awareness of the need to reduce the environmental footprint as well as improving the social and economic impacts of their supply chain activities, there is likely to be increasing pressure on aid agencies to adopt RL practices. This paper identifies some of the potential areas in which this can be undertaken, and the associated barriers to be overcome.

Originality/value
– To date, it would appear that no academic research has been undertaken into the RL practices within the HL sector. To this extent, the research represents a first look at a new sub-topic within the overall HL field.

Published: July 2015

AbstractNivolumab, a blockade of programmed cell death 1, is now administrated for advanced malignant melanomas. Nivolumab‐associated adverse events include organ‐specific autoimmune disorders; autoimmune thyroid disease, vitiligo and insulin‐dependent diabetes. However, predisposed persons are currently unknown. Here, we report serological aggravation of autoimmune thyroid disease in two cases receiving nivolumab: one with Hashimoto disease and another with probable subclinical Hashimoto disease. We should verify if nivolumab‐related hypothyroidism and hyperthyroidism are predisposed to occur in euthyroid individuals with subclinical autoimmune thyroid disease.

Published: July 2015

SummaryThe purpose of this study was to evaluate the probiotic properties of Enterococcus strains isolated from traditional naturally fermented cream in China. Four Enterococcus isolates showed high cholesterol removal ability in media were identified as Enterococcus durans (KLDS 6.0930 and 6.0933) and Enterococcus faecalis (KLDS 6.0934 and 6.0935) by 16S rRNA and pheS gene sequences, respectively, and selected for further evaluation. In order to assess the probiotic potential and safety of these strains, the property of four Enterococcus strains were examined, including acid and bile tolerance, adherence to Caco‐2 cells and antibiotics susceptibility. All four strains showed potential cholesterol assimilation, de‐conjugation of bile salts and/or cholesterol degradation to remove cholesterol in vitro. In addition, the potential effect of E. durans KLDS 6.0930 on serum cholesterol levels was evaluated in Sprague‐Dawley rats. After 4 weeks administration, compared with rats fed a high‐cholesterol diet without lactic acid bacteria supplementation, there was a significant (P < 0.05) decrease in the total cholesterol and low‐density lipoprotein cholesterol levels in the serum of rats treated with KLDS 6.0930. Furthermore, total bile acid level in the feces was significantly (P < 0.05) increased after KLDS 6.0930 administration. These observations suggested that the strain E. durans KLDS 6.0930 may be used in the future as a good candidate for lowering human serum cholesterol levels.

AbstractObjectiveTo evaluate the performance of human leukocyte antigen (HLA)‐B27 tag single nucleotide polymorphisms (SNPs) by polymerase chain reaction – restriction fragment length polymorphism (PCR–RFLP).MethodsWe genotyped three SNPs (rs116488202, rs13202464 and rs4349859). The primers were designed using Primer3 algorithm via primer‐BLAST interface. PCR products were digested by using NlaIII, BmrI and TaqαI enzymes. Quality control was performed by DNA sequence analysis.ResultsIn total, 207 patients with ankylosing spondylitis and 32 healthy controls were included in the study. The sensitivity and specificity of SNPs rs116488202 and rs4349859 in identifying HLA‐B27 were identical and adequate at 0.946 and 1.000, respectively. On the other hand, the sensitivity and specificity for rs13202464 was 0.878 and 0.934, respectively. The presence of another SNP (rs141774149) in close proximity to rs116488202 complicated the analysis for RFLP and required that we sequence all the T allele carrying samples.ConclusionThe SNPs rs116488202 and rs4349859 may have a place in the identification of HLA‐B27 in the Turkish population; however, methods other than PCR–RFLP should be considered.

Published: July 2015

SummaryProgressive retinal atrophy (PRA) is the collective name of a class of hereditary retinal dystrophies in the dog and is often described as the equivalent of retinitis pigmentosa in humans. PRA is characterized by visual impairment due to degeneration of the photoreceptors in the retina, usually leading to blindness. PRA has been reported in dogs from more than 100 breeds and can be genetically heterogeneous both between and within breeds. The disease can be subdivided by age at onset and rate of progression. Using genome‐wide association with 15 Shetland Sheepdog (Sheltie) cases and 14 controls, we identified a novel PRA locus on CFA13 (Praw = 8.55 × 10−7, Pgenome = 1.7 × 10−4). CNGA1, which is known to be involved in human cases of retinitis pigmentosa, was located within the associated region and was considered a likely candidate gene. Sequencing of this gene identified a 4‐bp deletion in exon 9 (c.1752_1755delAACT), leading to a frameshift and a premature stop codon. The study indicated genetic heterogeneity as the mutation was present in all PRA‐affected individuals in one large family of Shelties, whereas some other cases in the studied Sheltie population were not associated with this CNGA1 mutation. To our knowledge, this is the first report of a mutation in CNGA1 causing PRA in dogs.
CyGaMEs Selene player log dataset: Gameplay assessment, flow dimensions and non‐gameplay assessments
Authors: Reese Debbie Denise 
Published: July 2015

AbstractThe Selene: A Lunar Construction GaME instructional video game is a robust research environment (institutional review board approved) for investigating learning, affect, and the CyGaMEs Metaphorics approach to instructional video game design, embedded assessment, and informatics analysis and reporting. CyGaMEs applies analogical reasoning theory to translate fundamental scientific phenomena into embodied, procedural, goal‐driven, instructional gameplay and concurrent metrics of learning. Selene also collects integrated measures of affect operationalized as flow dimensions skill and challenge. Selene is a free, online Flash/Flex game available 24/7 to registered players. The player (agemean = 13; N = 3882; nfemale = 1915; nmale = 1908; nSpanish‐language version = 157) dataset, collected between April 6, 2010 and May 30, 2014, is anonymized, open and downloadable within Wheeling Jesuit University's data repository. Dataset files contain timestamped, tab‐delimited, player log data for gesture‐level gameplay; Timed Report progress toward each game/learning goal; flow dimensions; non‐gameplay assessments; demographics; paradata; and repository lexicons. Dataset analyses using traditional statistical methods (eg, multilevel modeling, interrupted time‐series) study learning trajectories, learning moments, affect (flow dimensions), persistence, gender differences, dashboard effects and the interactions among them. CyGaMEs Selene translates Timed Reports into real‐time, online dashboard report visualizations players and their registered educators can understand and use.
