Linking perceived organizational support to emotional labor
Authors: Kumar Mishra Sushanta 
Published: October 2014

Purpose– Based on two studies on different occupational groups, the purpose of this paper is to examine the relationship between perceived organizational support (POS) and different forms of emotional labor. Drawing from social identity theory, the present study extends the social exchange theory to provide an alternate explanation to the above relationships.Design/methodology/approach– The survey design following questionnaire in English language was physically administered among medical sales employees and subsequently among employees in the hospitality industry.Findings– The study found that POS is positively related to deep acting and negatively related to surface acting. The study further found that organizational identification mediates the relationship between POS and deep acting where as there was no mediation effect of organizational identification on the relationship between POS and surface acting.Research limitations/implications– The research relies on a cross-sectional design with a single source of data collected from two sources at different time periods.Practical implications– With the emergence of service economy there is an increasing emphasis on the performance of emotional labor. The present study suggests that organizations need to focus on organizational practices as employees’ perception of organizational support is related to the way they express their emotions during customer interactions. The finding of the study suggests that on what the organizations should do to motivate employees to perform expected emotional labor.Originality/value– The literature is relatively silent on the relationship between POS and different forms of emotional labor. The present study adds to the existing body of knowledge by explaining POS as an important antecedent of emotional labor. Further, the study contributes by exploring the mediation effect of organizational identification on the relationship between POS and different forms of emotional labor.

Authors: (Jessie) Lee Junghyun , Chaudhry Anjali , G. Tekleab Amanuel 
Published: October 2014

Purpose–The purpose of this paper is to investigate the inter-relationships among the closely related exchange-based constructs such as psychological contract (PC) breach, perceived organisational support (POS), and exchange ideology. The authors examine the effects of three-way interaction of them on employee performance.Design/methodology/approach– This study theoretically builds on a personality trait-based interactionist model of performance (Tett and Burnett, 2003) and empirically tests the model using multi-source data collected from employee-manager dyads in a non-profit organisation. Hierarchical linear modelling was employed for analysis.Findings– The results indicate a significant three-way interaction, such that, the negative relationship between PC breach and task performance is the strongest when employees with a high exchange ideology perceive low levels of POS.Practical implications– These findings suggest that organisations should ensure employees feel supported and pay special attention to employees with a high exchange ideology to minimise the harmful consequences of PC breachOriginality/value– The study provides new theoretical insights to PC literature by integrating the interactionist approach, cognitive psychology, and exchange ideology research. It highlights the importance of simultaneously examining both a situational and an individual variable in predicting employee performance after PC breach
Neighbourhood Spatial Order, the Local Economy and Firm Mobility in Urban Areas of the Netherlands
Authors: Beckers Pascal , Sleutjes Bart 
Published: October 2014

AbstractUrban residential neighbourhoods in the Netherlands increasingly function as incubation zones for small‐scale businesses. Despite this development, little is known about whether and how the local production environment in these neighbourhoods shapes firm mobility behaviour. This article studies how two aspects of the local production environment — the built neighbourhood environment and zoning regulations — affect firm mobility of small‐scale businesses in urban residential neighbourhoods. To achieve this aim, we contrast two sets of urban neighbourhoods, pre‐ and post‐second world war neighbourhoods with a comparable low socio‐economic profile, but with distinct built environments and zoning regulations. We combine quantitative and qualitative methods to analyse available trade register data from the Dutch regional Chambers of Commerce, study neighbourhood zoning regulations, and conduct focus‐group and individual interviews with neighbourhood experts and entrepreneurs. The local built environment and its regulations appear to have a small but significant effect on the firm mobility behaviour of entrepreneurs in the neighbourhoods studied. Relocation intentions are higher among entrepreneurs in post‐war than in pre‐war neighbourhoods, which may (in part) be attributed to less favourable local institutional settings for businesses, but actual firm mobility does not differ between these neighbourhoods.
The prevention and treatment of postpartum haemorrhage: what do we know, and where do we go to next?
Authors: Weeks A 
Published: October 2014

Postpartum haemorrhage (PPH) remains a major cause of maternal deaths worldwide, and is estimated to cause the death of a woman every 10 minutes. This review presents the latest clinical advice, including new evidence on controlled cord traction, misoprostol, and oxytocin. The controversy around the diagnosis of PPH, the limitations of universal prophylaxis, and novel ways to provide obstetric first aid are also presented. It ends with a call to develop high‐quality front‐line obstetric services that can deal rapidly with unexpected haemorrhages as well as minimising blood loss at critical times: major abruption, placenta praevia, and caesarean for prolonged labour.

Published: October 2014

ObjectiveThis study modeled the predictive power of unit/patient characteristics, nurse workload, nurse expertise, and hospital‐acquired pressure ulcer (HAPU) preventive clinical processes of care on unit‐level prevalence of HAPUs.Data SourcesSeven hundred and eighty‐nine medical‐surgical units (215 hospitals) in 2009.Study DesignUsing unit‐level data, HAPUs were modeled with Poisson regression with zero‐inflation (due to low prevalence of HAPUs) with significant covariates as predictors.Data Collection/Extraction MethodsHospitals submitted data on NQF endorsed ongoing performance measures to CALNOC registry.Principal FindingsFewer HAPUs were predicted by a combination of unit/patient characteristics (shorter length of stay, fewer patients at‐risk, fewer male patients), RN workload (more hours of care, greater patient [bed] turnover), RN expertise (more years of experience, fewer contract staff hours), and processes of care (more risk assessment completed).ConclusionsUnit/patient characteristics were potent HAPU predictors yet generally are not modifiable. RN workload, nurse expertise, and processes of care (risk assessment/interventions) are significant predictors that can be addressed to reduce HAPU. Support strategies may be needed for units where experienced full‐time nurses are not available for HAPU prevention. Further research is warranted to test these finding in the context of higher HAPU prevalence.
Survey of American (USA) Gasolines (2008)
Authors: Hetzel Susan S. 
Published: October 2014

AbstractThe regulations for gasoline's content vary depending on the time of year and physical location within the United States while the refinery and distribution system mixes product batches; this results in variability of content.ASTME1618 requires both the aromatic and alkaneEIPpatterns of gasoline to compare with references. A survey was conducted by collecting gasoline from Florida to Oregon, from 85 to 93 octane. Samples were analyzed in accordance withASTME1618 in various states of evaporation. The range of differences found in the 90% evaporated alkaneEIPs is presented and showed a continuum of response when the n‐alkane response was compared with the branched alkane response. Similarly, the ratio of the alkaneEIPto the aromaticEIPalso showed a continuum of response at the 90% evaporated state. Gasoline samples with unusual characteristics are also discussed.

Published: October 2014

AbstractIntroductionPreparation for postoperative radioiodine ablation for differentiated thyroid carcinoma is performed by either thyroid hormone withdrawal or recombinant human thyroid‐stimulating hormone (rhTSH) administration. There is little information on the impact of the method of preparation with respect to whole‐body effective I‐131 half‐life and its potential clinical implications in the Australian setting.MethodsA retrospective study was performed on patients admitted for adjuvant radioiodine ablation for non‐metastatic differentiated thyroid carcinoma at the Royal Adelaide Hospital over a 4½‐year period from 2009. Dose rate measurements were analysed for 19 rhTSH and 31 thyroid hormone withdrawal patients.ResultsThe mean effective I‐131 half‐lives were 11.51 and 13.29 h for the rhTSH and thyroid hormone withdrawal groups, respectively, with no statistically significant difference between the two groups (P = 0.761). This result differs from previously published data where withdrawal periods were typically longer, resulting in slower renal clearance and longer half‐lives for withdrawal patients.ConclusionsOur study did not demonstrate a significant difference in whole‐body effective half‐life of I‐131 between the two methods of preparation for radioiodine ablation. This suggests that putative advantages of rhTSH over withdrawal in terms of whole‐body radiation dose, duration of hospital admission and quality of life may be sensitive to duration of withdrawal.

Published: October 2014

AbstractIntroductionAlthough hypofractionated radiotherapy (HFRT) has become an accepted option for whole‐breast irradiation after breast‐conserving surgery, there is limited evidence to support HFRT to the chest wall following mastectomy. We retrospectively analysed post‐mastectomy patients treated with HFRT in Christchurch to determine whether HFRT yields acceptable efficacy and toxicity.MethodsThe Christchurch oncology database was used to identify breast cancer patients treated with adjuvant HFRT to the chest wall following a mastectomy between 2003 and 2008. Eligible post‐mastectomy patients were treated with 40 Gy in 16 daily fractions. Treatment outcomes assessed included local recurrence‐free survival, breast cancer survival, overall survival and acute toxicities.ResultsOne hundred thirty‐three patients were identified. The median follow‐up period was 5.03 years. Three patients had a local recurrence as a first event, resulting in 5‐year local recurrence‐free survival of 97.6%. Five‐year overall survival and 5‐year breast cancer survival were 74.7% and 77.7%, respectively. The prospectively assessed acute toxicities were mostly grade 1. In particular, the incidence of grade 2 skin toxicity was 10.7%, and no patients experienced grade 3 skin toxicity.ConclusionThe high local control rate with HFRT, combined with acceptable toxicity and the practical benefits of a shorter treatment time, supports its ongoing use in the eligible patient group. A randomised controlled trial would be necessary to more completely assess the acute and long‐term toxicity of HFRT compared with standard fractionation.

AbstractAimTo assess vitamin D levels in rheumatoid arthritis (RA) patients and to find their relation to clinical parameters, fibromyalgia syndrome (FMS), quality of life (QoL) and disease activity.MethodsThe study included 63 RA patients and 62 controls. Clinical examination and laboratory investigations were performed. For patients, the Disease Activity Score (DAS‐28), QoL index, Health Assessment Questionnaire II (HAQ II) and Modified Larsen score were calculated. 25‐OH‐vitamin D was measured in patients and controls.ResultsThe patients’ mean age was 41.59 ± 9.69 years and disease duration 5.89 ± 3.67 years. The level of vitamin D in RA patients was significantly lower (23.11 ± 12.71 ng/mL) than that in the controls (32.59 ± 13.06 ng/mL) (P = 0.005) being deficient in 50.8%, insufficient in 23.8% and normal in 25.4%. The RA patients with FMS (n = 33) had significantly lower levels of vitamin D (19.08 ± 10.59 ng/mL) than those without (27.55 ± 13.51 ng/mL) (P = 0.008). The difference was significant on comparing those receiving hydroxychloroquine (17.39 ± 7.84 ng/mL) to those not (31.85 ± 13.85 ng/mL) (P < 0.001). Vitamin D significantly correlated with QoL index (r = 0.58, P < 0.001) and negatively with HAQ II (r = −0.36, P = 0.004) and BMI (r = −0.39, P = 0.001).ConclusionSpecial attention is required regarding vitamin D levels in RA patients with FMS and decreased QoL. Vitamin D should be corrected and supplementation considered among the RA management armamentarium.

Authors: Su Lin , Li Na , Huo Xueyun 
Published: October 2014

AbstractBackgroundFew genetic markers useful for the screening of lung cancer risk exist. Although related research has shown that certain expression profiles of micro ribonucleic acids (miRNAs) are different in lung cancer versus the normal lung, such as miR‐29a and miR‐29s, the precise molecular mechanism of lung cancer remains obscure. In order to get a better understanding of the pathogenetic mechanism of lung cancer, we analyzed the differentially expressed genes (DEGs) and identified featured miRNAs in lung cancer tissues.MethodsWe used the gene expression profile GSE10072, including 49 gene chips of non‐tumor tissues and 58 gene chips of lung tumor specimens. The DEGs between these two groups were identified by Limma package in R language. The TarBase database was used to construct the networks of miRNA regulating DEGs related to lung cancer. After ordering miRNAs regulating DEGs, we further screened featured miRNAs combined with the miR2Disease database.ResultsA total of 5572 DEGs were obtained between lung cancer and control specimens. After constructing a miRNA regulatory network, a total of 398 regulations between 57 miRNAs and 321 target genes existed. By intergrating the miR2Disease database and using a sorting algorithm, a total of six featured miRNAs related to lung cancer were identified, including miR‐520h, miR‐133a, miR‐34, miR‐103, miR‐370, and miR‐148. They might be involved in lung cancer progression by regulating ABCG2, PKM2, VAMP2, GPD1, MAP3K8, and DNMT3B, respectively.ConclusionThe top 10 significant miRNAs, such as miR‐520h, miR‐133a, miR‐34, and miR‐103 may be potential therapeutic targets for lung cancer.

BackgroundThe GABAergic neuroactive steroid (3α,5α)‐3‐hydroxy‐pregnan‐20‐one (3α,5α‐THP; allopregnanolone) has been studied during withdrawal from ethanol (EtOH) in humans, rats, and mice. Serum 3α,5α‐THP levels decreased, and brain levels were not altered following acute EtOH administration (2 g/kg) in male C57BL/6J mice; however, the effects of chronic intermittent ethanol (CIE) exposure on 3α,5α‐THP levels have not been examined. Given that CIE exposure changes subsequent voluntary EtOH drinking in a time‐dependent fashion following repeated cycles of EtOH exposure, we conducted a time‐course analysis of CIE effects on 3α,5α‐THP levels in specific brain regions known to influence drinking behavior.MethodsAdult male C57BL/6J mice were exposed to 4 cycles of CIE to induce EtOH dependence. All mice were sacrificed and perfused at 1 of 2 time points, 8 or 72 hours following the final exposure cycle. Free‐floating brain sections (40 μm; 3 to 5 sections/region/animal) were immunostained and analyzed to determine relative levels of cellular 3α,5α‐THP.ResultsWithdrawal from CIE exposure produced time‐dependent and region‐specific effects on immunohistochemical detection of 3α,5α‐THP levels across cortical and limbic brain regions. A transient reduction in 3α,5α‐THP immunoreactivity was observed in the central nucleus of the amygdala 8 hours after withdrawal from CIE (−31.4 ± 9.3%). Decreases in 3α,5α‐THP immunoreactivity were observed 72 hours following withdrawal in the medial prefrontal cortex (−25.0 ± 9.3%), nucleus accumbens core (−29.9 ± 6.6%), and dorsolateral striatum (−18.5 ± 6.0%), while an increase was observed in the CA3 pyramidal cell layer of the hippocampus (+42.8 ± 19.5%). Sustained reductions in 3α,5α‐THP immunoreactivity were observed at both time points in the lateral amygdala (8 hours −28.3 ± 12.8%; 72 hours −27.5 ± 12.4%) and in the ventral tegmental area (8 hours −26.5 ± 9.9%; 72 hours −31.6 ± 13.8%).ConclusionsThese data suggest that specific neuroadaptations in 3α,5α‐THP levels may be present in regions of brain that mediate anxiety, stress, and reinforcement relevant to EtOH dependence. The changes that occur at different time points likely modulate neurocircuitry involved in EtOH withdrawal as well as the elevated drinking observed after CIE exposure.

ObjectiveTo examine whether non‐psychiatric hospitalizations rates were higher in those with mental disorders.MethodIn a cohort of 15 811 employees, aged 35–50 years in 1989, mental disorder status was defined from 1989 to 2000. Hospitalizations for all‐causes, myocardial infarction (MI), stroke, and cancer, were recorded yearly from 2001 to 2011. Negative binomial regression models were used to estimate hospitalization rates over the follow‐up.ResultsAfter controlling for baseline sociodemographic factors, health‐related behaviors, self‐rated health, and self‐reported medical conditions, participants with a mental disorder had significantly higher rates of all‐cause hospitalization [incidence rate ratio, IRR = 1.20 (95%, 1.14–1.26)], as well as hospitalization due to MI [IRR = 1.44 (95%, 1.12–1.85)]. For stroke, the IRR did not reach statistical significance [IRR = 1.37 (95%, 0.95–1.99)] and there was no association with cancer [IRR = 1.01 (95%, 0.86–1.19)]. A similar trend was observed when mental disorders groups were considered (no mental disorder, depressive disorder, mental disorders due to psychoactive substance use, other mental disorders, mixed mental disorders, and severe mental disorder).ConclusionIn this prospective cohort of employees with stable employment as well as universal access to healthcare, we found participants with mental disorders to have higher rates of non‐psychiatric hospitalizations.
What has research over the past two decades revealed about the adverse health effects of recreational cannabis use?
Authors: Hall Wayne 
Published: October 2014

AbstractAimsTo examine changes in the evidence on the adverse health effects of cannabis since 1993.MethodsA comparison of the evidence in 1993 with the evidence and interpretation of the same health outcomes in 2013.ResultsResearch in the past 20 years has shown that driving while cannabis‐impaired approximately doubles car crash risk and that around one in 10 regular cannabis users develop dependence. Regular cannabis use in adolescence approximately doubles the risks of early school‐leaving and of cognitive impairment and psychoses in adulthood. Regular cannabis use in adolescence is also associated strongly with the use of other illicit drugs. These associations persist after controlling for plausible confounding variables in longitudinal studies. This suggests that cannabis use is a contributory cause of these outcomes but some researchers still argue that these relationships are explained by shared causes or risk factors. Cannabis smoking probably increases cardiovascular disease risk in middle‐aged adults but its effects on respiratory function and respiratory cancer remain unclear, because most cannabis smokers have smoked or still smoke tobacco.ConclusionsThe epidemiological literature in the past 20 years shows that cannabis use increases the risk of accidents and can produce dependence, and that there are consistent associations between regular cannabis use and poor psychosocial outcomes and mental health in adulthood.

SummaryNext‐generation sequencing technologies permit rapid and cost‐effective identification of numerous putative microsatellite loci. Here, from the genome sequences of Japanese quail, we developed microsatellite markers containing dinucleotide repeats and employed these for characterisation of genetic diversity and population structure. A total of 385 individuals from 12 experimental and one wild‐derived Japanese quail lines were genotyped with newly developed autosomal markers. The maximum number of alleles, expected heterozygosity and polymorphic information content (PIC) per locus were 10, 0.80 and 0.77 respectively. Approximately half of the markers were highly informative (PIC ≥ 0.50). The mean number of alleles per locus and observed heterozygosity within a line were in the range of 1.3–4.1 and 0.11–0.53 respectively. Compared with the wild‐derived line, genetic diversity levels were low in the experimental lines. Genetic differentiation (FST) between all pairs of the lines ranged from 0.13 to 0.83. Genetic clustering analyses based on multilocus genotypes of individuals showed that most individuals formed clearly defined clusters corresponding to the origins of the lines. These results suggest that Japanese quail experimental lines are highly structured. Microsatellite markers developed in this study may be effective for future genetic studies of Japanese quail.
