Speaking up when feeling job insecure
Authors: Schreurs Bert , Guenter Hannes , Jawahar I.M. 'Jim' , De Cuyper Nele 
Published: October 2015

Purpose– The purpose of this paper is to investigate the extent to which felt job insecurity facilitates or hinders employees from raising voice (i.e. speaking up to their authority). The authors introduce punishment and reward sensitivity, two constructs of reinforcement sensitivity theory, as dispositional factors that might lead employees to appraise felt job insecurity as a hindrance vs challenge stressor. The authors propose employees high on punishment sensitivity to feel more constrained in raising voice because felt job insecurity to them is akin to a threat. Employees high on reward sensitivity should see felt job insecurity as a challenge, making it more likely that they will speak up.Design/methodology/approach– Hypotheses were tested using moderated structural equation modeling analysis. The sample consisted of 232 employees confronted with organizational change.Findings– The results are in line with the view of felt job insecurity as a hindrance stressor. Felt job insecurity negatively affected voice among both high and low punishment-sensitive individuals. Similarly, felt job insecurity was negatively related to voice in both low and high reward-sensitive individuals, although in the latter group the relationship was less pronounced.Originality/value– The literatures on felt job insecurity and voice have developed parallel to one another, without much cross-dialogue. Furthermore, the few existing studies that did relate felt job insecurity to employee voice have yielded conflicting results. The present study offers a theoretical account of the existing ambiguities in the literature, and generates new insights into why some employees more than others react to felt job insecurity by self-censoring their ideas and opinions.
Climate, communication and participation impacting commitment to change
Authors: Rogiest Sofie , Segers Jesse , van Witteloostuijn Arjen 
Published: October 2015

Purpose– Through the combination of change process, context and content the purpose of this paper is to provide a deeper understanding of failure or success of organizational change. This study considers the effect of organizational climate on affective commitment to change simultaneously with quality change communication and employee participation during the change process, while controlling for perceived change impact.Design/methodology/approach– The findings are based on 134 survey responses gathered through surveys in two police forces that recently underwent a merger.Findings– First, quality change communication is the only process variable that directly impacts affective commitment to change. Second, the results indicate that an involvement-oriented climate positively affects affective commitment to change, mediated through quality change communication.Originality/value– First, the general understanding of the impact of climate on organizational change is very limited. Second, employee participation and quality change communication are generally studied together. The authors propose that both process variables each have their unique impact on attitudes toward change.
The complexity of wicked problems in large scale change

Published: October 2015

Purpose– The purpose of this paper is to extend and elaborate the notion of successful organizational change to incorporate the concept of large system change (LSC), by developing a framework that brings together complexity and wicked problems theories to understand how individual organizations and change agents can better influence LSC.Design/methodology/approach– This conceptual paper integrates wicked problems and complexity theories to understand and cope with large system initiatives from the perspective of change agents in organizations, and uses the case of the electricity system as an illustrative example for these concepts.Findings– The paper provides implications for LSC and action steps for change agents in organizations, arguing that by understanding change initiatives through the lenses of complexity and wicked problems, change agents are likely to be more effective.Research limitations/implications– The integration of complexity science and wicked problems underpins the development of a comprehensive framework for creating effective LSC solutions, however, these ideas still need to be grounded in practice and empirical research.Practical implications– Using these ideas, change agents in organizations can enhance their influence and use the power of system dynamics to support positive action for sustainable change. This paper provides a foundation to help think through the cross-sectoral, inter-organizational, and change dynamics involved in LSC efforts needed to bring about a more sustainable, secure, and equitable world for all.Social implications– The world greatly needs system change; however, there is limited theory on effective LSC. This paper hopes to contribute to understanding the ways in which the difficulties of such change can be harnessed to move in positive directions with minimal disruption and greatest effectiveness.Originality/value– Theories of change management that position the organization in the context of a broader system and define its role in creating change do not yet articulate the nature of the problems at hand in relation to the large systems where they are embedded. This paper builds upon wicked problems and complexity theories to shed light on the role of change agents and organizations in effective transformational change.
Geographic structure of genetic and phenotypic variation in the hybrid zone betweenQuercus affinisandQ. laurinainMexico
Authors: Ramos‐Ortiz S. , Oyama K. , Rodríguez‐Correa H. , González‐Rodríguez A. 
Published: October 2015

AbstractAnalyzing the structure of hybrid zones is important for inferring their origin, dynamics and evolutionary significance. We examined the geographic structure of phenotypic and genetic variation in the contact zone between two Mexican red oaks,Quercus affinisandQ. laurina. A total of 105 individuals from seven populations were sampled along a 600‐km latitudinal gradient representing the distribution area of the two species and their contact zone. Individuals were genotyped for nine nuclear and four chloroplastDNAmicrosatellite loci (ncSSRand cpSSR, respectively), and characterized for several leaf and acorn traits. The cpSSR data revealed extensive haplotype sharing among populations of the two species, while a Bayesian assignment analysis based on ncSSRs identified two main genetic groups, each corresponding to one of the species, and two populations in the contact zone showing evidence of admixture. The proportion of genetic ancestry in the populations was strongly associated with latitude and showed a pattern of variation with the shape of a narrow sigmoidal cline. The variation in three of the seven phenotypic traits was partially congruent with molecular variation, while the other traits did not conform to a geographic cline but instead were correlated with environmental variables. In conclusion, the hybrid zone between the two oak species has some of the characteristics of a tension zone, but heterogeneous variation across traits suggests differential introgression and the action of extrinsic selection.
Disease‐Specific Trends of Comorbidity Coding and Implications for Risk Adjustment in Hospital Administrative Data
Authors: Nimptsch Ulrike 
Published: October 2015

ObjectiveTo investigate changes in comorbidity coding after the introduction of diagnosis related groups (DRGs) based prospective payment and whether trends differ regarding specific comorbidities.Data SourcesNationwide administrative data (DRG statistics) from German acute care hospitals from 2005 to 2012.Study DesignObservational study to analyze trends in comorbidity coding in patients hospitalized for common primary diseases and the effects on comorbidity‐related risk of in‐hospital death.Extraction MethodsComorbidity coding was operationalized by Elixhauser diagnosis groups. The analyses focused on adult patients hospitalized for the primary diseases of heart failure, stroke, and pneumonia, as well as hip fracture.Principal FindingsWhen focusing the total frequency of diagnosis groups per record, an increase in depth of coding was observed. Between‐hospital variations in depth of coding were present throughout the observation period. Specific comorbidity increases were observed in 15 of the 31 diagnosis groups, and decreases in comorbidity were observed for 11 groups. In patients hospitalized for heart failure, shifts of comorbidity‐related risk of in‐hospital death occurred in nine diagnosis groups, in which eight groups were directed toward the null.ConclusionsComorbidity‐adjusted outcomes in longitudinal administrative data analyses may be biased by nonconstant risk over time, changes in completeness of coding, and between‐hospital variations in coding. Accounting for such issues is important when the respective observation period coincides with changes in the reimbursement system or other conditions that are likely to alter clinical coding practice.

Authors: Duong Trang , Balaban Murat , Perera Conrad , Bi Xiufang 
Published: October 2015

AbstractHigh hydrostatic pressure (HHP) is used for microbial inactivation in foods. Addition of carbon dioxide (CO2) to HHP can improve microbial and enzyme inactivation. This study investigated microbial effects of combined HHP and CO2 on Escherichia coli, Bacillus subtilis, and Saccharomyces cerevisiae, and evaluated sensory attributes of treated feijoa fruit puree (pH 3.2).Microorganisms in their growth media and feijoa puree were treated with HHP alone (HHP), or saturated with CO2 at 1 atm (HHPcarb), or 0.4%w/w of CO2 was injected into the package (HHPcarb+CO2). Microbial samples were processed at 200 to 400 MPa, 25 °C, 2 to 6 min. Feijoa samples were processed at 600 MPa, 20 °C, 5 min, then served with and without added sucrose (10%w/w). Treated samples were analyzed for microbial viability and sensory evaluation.Addition of CO2 enhanced microbial inactivation of HHP from 1.7‐log to 4.3‐log reduction in E. coli at 400 MPa, 4 min, and reduction of >6.5 logs in B. subtilis (vegetative cells) starting at 200 MPa, 2 min. For yeast, HHPcarb+CO2 increased the inactivation of HHP from 4.7‐log to 6.2‐log reduction at 250 MPa, 4 min. The synergistic effect of CO2 with HHP increased with increasing time and pressure. HHPcarb+CO2 treatment did not alter the appearance and color, while affecting the texture and flavor of unsweetened feijoa samples. There were no differences in sensory attributes and preferences between HHPcarb+CO2 and fresh sweetened products. Addition of CO2 in HHP treatment can reduce process pressure and time, and better preserve product quality.

Published: October 2015

AbstractEncapsulation of hydrophobic plant essential oil components (EOC) into surfactant micelles can assist the decontamination of fresh produce surfaces from bacterial pathogens during postharvest washing. Loading of eugenol and carvacrol into surfactant micelles of polysorbate 20 (Tween 20), Surfynol® 485W, sodium dodecyl sulfate (SDS), and CytoGuard® LA 20 (CG20) was determined by identification of the EOC/surfactant‐specific maximum additive concentration (MAC). Rheological behavior of dilute EOC‐containing micelles was then tested to determine micelle tolerance to shearing. Antimicrobial efficacy of EOC micelles against Escherichia coli O157:H7 and Salmonella enterica serotype Saintpaul was first evaluated by the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Pathogen‐inoculated spinach was treated with eugenol‐containing micelles applied via spraying or immersion methods. SDS micelles produced the highest MACs for EOCs, while Tween 20 loaded the lowest amount of EOCs. Micelles demonstrated Newtonian behavior in response to shearing. SDS and CG20‐derived micelles containing EOCs produced the lowest MICs and MBCs for pathogens. E. coli O157:H7 and S. Saintpaul were reduced on spinach surfaces by application of eugenol micelles, though no differences in numbers of surviving pathogens were observed when methods of antimicrobial micelle application (spraying, immersion) was compared (P ≥ 0.05). Data suggest eugenol in SDS and CG20 micelles may be useful for produce surface decontamination from bacterial pathogens during postharvest washing.

Published: October 2015

AbstractThe objective of this study was to evaluate the fate of Staphylococcus aureus, Listeria monocytogenes, and natural microbiota on fresh‐cut tropical fruits (pitaya, mango, papaya and pineapple) with commercial PVC film at different storage temperature (5, 13, and 25 °C). The results showed that S. aureus, L. monocytogenes, and natural microbiota increased significantly on fresh‐cut tropical fruits at 25 °C. Both pathogen and natural microbiota were able to grow on fresh‐cut tropical fruits at 13 °C. The maximum population of L. monocytogenes was higher than that of S. aureus on fresh‐cut tropical fruits. L. monocytogenes and S. aureus could survive without growth on fresh‐cut pitaya, mango, and papaya at 5 °C. The population of L. monocytogenes declined significantly on fresh‐cut pineapple at all temperature, indicating composition of fresh‐cut pineapple could inhibit growth of L. monocytogenes. However, S. aureus was still able to grow on fresh‐cut pineapple at storage temperature. Thus, this study suggests that 4 kinds of fresh‐cut tropical fruits (pitaya, mango, papaya, and pineapple) should be stored at low temperature to extend shelf life as well as to ensure the safety of fresh‐cut fruits.
Effects of Combined High Hydrostatic Pressure and Dense Phase Carbon Dioxide on the Activity, Structure and Size of Polyphenoloxidase
Authors: Duong Trang , Balaban Murat , Perera Conrad 
Published: October 2015

AbstractHigh hydrostatic pressure (HHP) may activate undesirable enzymes such as polyphenoloxidase (PPO). Carbon dioxide (CO2) addition to HHP could increase enzyme inactivation. We investigated the inactivation of combined HHP and dense phase carbon dioxide process on activity, secondary conformation and size of pure PPO from mushroom. Solutions (2.35μM, in phosphate buffer pH 6.8) were treated with HHP alone (HHP), or 3.6% w/w of CO2 was injected into the package (HHP+CO2). Treatment conditions were 600 MPa, 20 °C, for 1, 3, 5, 7, and 9 min. HHP+CO2 treatment significantly decreased residual enzyme activity (REA) to 30% to 12% after 1 to 9 min, respectively, whereas only HHP had no significant effect. Both HHP and HHP+CO2 treatments caused changes in secondary conformations, however HHP+CO2 changes were more extensive. Alpha‐helix fractions were reduced by 32% and 41%, while β sheet, turn and unordered increased by 63% and 213%, 100% and 71%, and 118% and 82% for HHP and HHP+CO2, respectively after 9 min. The protein size in HHP+CO2 samples was 5‐ to 6‐fold larger than that of Control and HHP treatment, and this increase was inversely correlated with REA. The best inactivation kinetics of HHP+CO2 model was the 2‐fractional model with 2 simultaneous 1st‐order steps, contributing 70% and 30% to original enzyme activity, with klabile = 12.15 min−1 and kstable = 0.07 min−1, respectively. No recovery in activity, secondary conformation and size in all samples were observed after 1‐mo storage. Addition of CO2 in HHP treatment can improve enzyme inactivation, and therefore product shelf‐life and quality.
CRISPR‐Based Technologies and the Future of Food Science

Published: October 2015

AbstractThe on‐going CRISPR craze is focused on the use of Cas9‐based technologies for genome editing applications in eukaryotes, with high potential for translational medicine and next‐generation gene therapy. Nevertheless, CRISPR‐Cas systems actually provide adaptive immunity in bacteria, and have much promise for various applications in food bacteria that include high‐resolution typing of pathogens, vaccination of starter cultures against phages, and the genesis of programmable and specific antibiotics that can selectively modulate bacterial population composition. Indeed, the molecular machinery from these DNA‐encoded, RNA‐mediated, DNA‐targeting systems can be harnessed in native hosts, or repurposed in engineered systems for a plethora of applications that can be implemented in all organisms relevant to the food chain, including agricultural crops trait‐enhancement, livestock breeding, and fermentation‐based manufacturing, and for the genesis of next‐generation food products with enhanced quality and health‐promoting functionalities. CRISPR‐based applications are now poised to revolutionize many fields within food science, from farm to fork. In this review, we describe CRISPR‐Cas systems and highlight their potential for the development of enhanced foods.

AbstractAimAlthough Takayasu arteritis (TAK) and giant cell arteritis (GCA) have been considered as distinct disease entities, similarities of these diseases have been recently reported. However, little data is available regarding this issue in Japanese patients with TAK and GCA. In addition, the classification criteria for TAK established in 1990 by the American College of Rheumatology (ACR) have been criticized due to the age restriction for disease onset (≤ 40 years). Thus, we aimed to compare the clinical characteristics of Japanese patients with TAK and those with GCA and to clarify whether clinical differences existed between patients with early‐onset (≤ 40 years) and late‐onset (> 40 years) TAK.MethodsWe enrolled 86 patients with TAK and nine with GCA who visited our department from 1990 to 2014. The diagnoses of TAK and GCA were based on the criteria of the Japanese Circulation Society and the ACR, respectively.ResultsMean ages at onset for TAK and GCA were 36.4 and 71.0 years, respectively. Patients with TAK had significantly higher incidences of aortic regurgitation and carotid and subclavian arterial involvement, lower frequencies of polymyalgia rheumatica, and better prognoses than those with GCA. In contrast, the clinical characteristics, distribution of arterial lesions, treatments administered, and prognoses of patients with early‐ and late‐onset TAK were comparable.ConclusionsThese results suggested that TAK and GCA differed substantially, and that the age restriction (≤ 40 years) may not be necessary for the diagnosis of TAK.
Resistance to Temptation: The Interaction of External and Internal Control on Alcohol Use During Residential Treatment for Alcohol Use Disorder

Published: October 2015

BackgroundThere is evidence that drinking during residential treatment is related to various factors, such as patients' general control beliefs and self‐efficacy, as well as to external control of alcohol use by program's staff and situations where there is temptation to drink. As alcohol use during treatment has been shown to be associated with the resumption of alcohol use after discharge from residential treatment, we aimed to investigate how these variables are related to alcohol use during abstinence‐oriented residential treatment programs for alcohol use disorders (AUD).MethodsIn total, 509 patients who entered 1 of 2 residential abstinence‐oriented treatment programs for AUD were included in the study. After detoxification, patients completed a standardized diagnostic procedure including interviews and questionnaires. Drinking was assessed by patients' self‐report of at least 1 standard drink or by positive breathalyzer testing. The 2 residential programs were categorized as high or low control according to the average number of tests per patient.ResultsRegression analysis revealed a significant interaction effect between internal and external control suggesting that patients with high internal locus of control and high frequency of control by staff demonstrated the least alcohol use during treatment (16.7%) while patients with low internal locus of control in programs with low external control were more likely to use alcohol during treatment (45.9%). No effects were found for self‐efficacy and temptation.ConclusionsAs alcohol use during treatment is most likely associated with poor treatment outcomes, external control may improve treatment outcomes and particularly support patients with low internal locus of control, who show the highest risk for alcohol use during treatment. High external control may complement high internal control to improve alcohol use prevention while in treatment.
