Authors: Gaviria-Marin Magaly , Merigo Jose M. , Popa Simona 
Published: June 2018

PurposeIn 2017, theJournal of Knowledge Management(JKM) celebrates its 20th anniversary. This study aims to show an updated analysis of their publications to provide a general overview of the journal, focusing on a bibliometric analysis of its publications between 1997 and 2016.Design/methodology/approachThe methodology involves two procedures: a performance analysis and a science mapping analysis of JKM. The performance analysis uses a series of bibliometric indicators such ash-index, productivity and citations. This analysis considers different dimensions, including papers, authors, universities and countries. VOSviewer software is used to carry out the mapping of science of JKM, which, based on the concurrence of key words and co-citation points of view, seeks to graphically analyze the structure of the references of this journal.FindingsThere is a positive evolution in the number of publications (although with certain oscillations), which shows a growing interest in publishing in JKM. The USA and the UK lead the publications in this journal, although at a regional level, Europe is the most productive. The low participation of emerging economies in JKM is also observed.Practical implicationsThe paper will identify the leading trends in the journal in terms of papers, authors, institutions, countries, journals and keywords. This study is useful for obtaining a quick snapshot of what is happening in the journal.Originality/valueFrom the historical record of JKM publications, this study presents an exclusive bibliometric analysis of its publications until 2016 and identifies its main trends.
Frontiers of efficiency wages: unconventional wisdom?
Authors: Morris Morant Rosetta A. , Jacobs David C. 
Published: June 2018

PurposeThe purpose of this paper is to trace the historical foundation of the efficiency wage theory and examine its conceptual framework against other wage theories, in relation to conventional practices in human resource management.Design/methodology/approachFollowing a description of various wage theories, a conceptual analysis maps the evolutionary process of efficiency wage theory.FindingsThe concept of efficiency being applied to wages appears to evolve from Smith. The difference between the classical and the institutionalists’ perspectives appears to be the meaning ascribed to efficiency. Clark seemed to be the first one to examine the relationship between labor and productivity. Webb expanded the meaning of efficiency and demonstrated the relationship with productivity. Institutional and behavioral theorists further developed and advocated for efficiency wages. A synthesis of recent empirical studies provides support for the theory, which challenges conventional human resource management wage practices.Practical implicationsThe findings solidify the usefulness of efficiency wage theory not only as a motivational management tool but also as a source for social and economic well-being.Originality/valueThe contribution of this historical account is that it synthesizes the root and development of efficiency wages theory. It also highlights the social context of the theory and provides an interface between economic and management perspectives.
A qualitative study on electricity energy-saving behaviour
Authors: Sony Michael , Mekoth Nandakumar 
Published: June 2018

PurposeThere is an unresolved paradox concerning electricity energy-saving behaviour. On one hand, there are many studies on energy-saving behaviours and on the other hand, recent research stresses that there exists large amount untapped potential in terms electricity energy-saving behaviours. Therefore, it becomes pertinent to revisit the construct of electricity energy-saving behaviours qualitatively to enlarge the spectrum of understanding. The purpose of this paper is to answer the research question why do not customers care about electricity energy-saving behaviours.Design/methodology/approachA qualitative study is undertaken in Western India using grounded theory methodology. The basic steps in the analysis of qualitative data consist of coding the data, combining the codes into broader categories and themes, and interpreting the results.FindingsThe study identifies seven categories of determinants of electricity energy-saving behaviours. Policy implications and limitations of the study are discussed along with areas of future research directions.Originality/valueThis is the first study to unearth the dimensions of electricity energy-saving behaviour.

Authors: Wang Xiaoqin , Jia Zhongzhi , Shi Haifeng , Pan Changjie 
Published: June 2018

SummaryThe circulating miRNAs are dysregulated in non‐small cell lung cancer (NSCLC) and have great promise for clinical diagnosis. The aim of this study was to screen and evaluate the reliability and diagnostic efficiency of candidate serum miRNAs for NSCLC diagnosis. We found that miR‐21 and let‐7a were significantly dysregulated in NSCLC patients (P < .001). When applied for NSCLC diagnosis, combined application of miR‐21 and let‐7a had a sensitivity of 0.790, specificity of 0.750, which is significantly higher than application alone of miR‐21(sensitivity 0.647; specificity 0.641), let‐7a (sensitivity 0.653; specificity 0.718) or computed tomography‐guided core‐needle biopsy (CTCB) (sensitivity 0.725; specificity 0.609) (P < .01). In conclusion, our study indicates that combined application of circulating miR‐21 and let‐7a has advantages over traditional CTCB technique.

Published: June 2018

BackgroundSeveral randomised controlled trials (RCTs) have investigated the usefulness of pituitary block with gonadotrophin‐releasing hormone (GnRH) antagonists during intrauterine insemination (IUI) cycles, with conflicting results.ObjectiveThe aim of the present systematic review and meta‐analysis of RCTs was to evaluate the effectiveness of GnRH antagonist administration as an intervention to improve the success of IUI cycles.Search strategyElectronic databases (MEDLINE, Scopus, EMBASE, Sciencedirect) and clinical registers were searched from their inception until October 2017.Selection criteriaRandomised controlled trials of infertile women undergoing one or more IUI stimulated cycles with GnRH antagonists compared with a control group.Data collection and analysisThe primary outcomes were ongoing pregnancy/live birth rate (OPR/LBR) and clinical pregnancy rate (CPR). Pooled results were expressed as odds ratio (OR) or mean differences with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. The body of evidence was rated using GRADE methodology. Publication bias was assessed with funnel plot, Begg's and Egger's tests.Main resultsFifteen RCTs were included (3253 IUI cycles, 2345 participants). No differences in OPR/LBR (OR 1.14, 95% CI 0.82–1.57, P = 0.44) and CPR (OR 1.28, 95% CI 0.97–1.69, P = 0.08) were found. Sensitivity and subgroup analyses did not provide statistical changes in pooled results. The body of evidence was rated as low (GRADE 2/4). No publication bias was detected.ConclusionPituitary block with GnRH antagonists does not improve OPR/LBR and CPR in women undergoing IUI cycles.Tweetable abstractPituitary block with GnRH antagonists does not improve the success of IUI cycles.
Directing Improvements in Primary Care Patient Experience through Analysis of Service Quality
Authors: Hudson Smith Mel , Smith David 
Published: June 2018

ObjectiveTo examine the influence of dimensions of service quality on patient experience of primary care.Data Sources/Study SettingData from the national GP Patient Survey in England 2014/15, with responses from 858,351 patients registered at 7,918 practices.Study DesignExpert panel and principal component analysis helped identify relevant dimensions of service quality. Regression was then used to examine the relationships between these dimensions and reported patient experience.Data Collection/Extraction MethodsAggregated scores for each practice were used, comprising the proportion of positive responses to each element of the study.Principal FindingsOf eight service quality dimensions identified, six have statistically significant impacts on patient experience but only two have large effects. Patient experience is highly influenced by practice responsiveness and the interactions with the physician. Other dimensions have small or even slightly negative influence. Service quality provided by nurses has negligible effect on patient experience.ConclusionsTo improve patient experience in primary health care, efforts should focus on practice responsiveness and interactions with the physician. Other areas have little influence over patient experience. This suggests a gap in patients’ perspectives on health care, which has policy implications for patient education.
A systematic review on the quality, validity and usefulness of current cost‐effectiveness studies for treatments of neovascular age‐related macular degeneration
Authors: Elshout Mari , Webers Carroll A.B. , van der Reis Margriet I. , Schouten Jan S.A.G. 
Published: June 2018

AbstractPurposeOphthalmologists increasingly depend on new drugs to advance their treatment options. These options are limited by restraints on reimbursements for new and expensive drugs. These restraints are put in place through health policy decisions based on cost‐effectiveness analyses (CEA). Cost‐effectiveness analyses need to be valid and of good quality to support correct decisions to create new treatment opportunities. In this study, we report the quality, validity and usefulness of CEAs for therapies for nAMD.MethodsA systematic review in PubMed, EMBASE and Cochrane was performed to include CEAs. Quality and validity assessment was based on current general quality criteria and on elements that are specific to the field of ophthalmology.ResultsForty‐eight CEAs were included in the review. Forty‐four CEAs did not meet four basic model quality and validity criteria specific to CEAs in the field of ophthalmology (both eyes analysed instead of one; a time horizon extending beyond 4 years; extrapolating VA and treatment intervals beyond trial data realistically; and including the costs of low‐vision). Four CEAs aligned with the quality and validity criteria. In two of these CEAs bevacizumab as‐needed (PRN) was more cost‐effective than bevacizumab monthly; aflibercept (VIEW); or ranibizumab monthly or PRN. In two CEAs, ranibizumab (PRN or treat and extent) was dominant over aflibercept. In two other CEAs, aflibercept was either more cost‐effective or dominant over ranibizumab monthly or PRN.ConclusionTwo of the CEAs of sufficient quality and validity show that bevacizumab PRN is the most cost‐effective treatment. Comparing ranibizumab and aflibercept, either treatment can be more cost‐effective depending on the assumptions used for drug prices and treatment frequencies. The majority of the published CEAs are of insufficient quality and validity. They wrongly inform decision‐makers at the cost of opportunities for ophthalmologists to treat patients. As such, they may negatively influence overall patient outcomes and societal costs. For future ophthalmic treatments, CEAs need to be improved and only published when they are of sufficient quality and validity.

AbstractPurposeA limited number of therapies are available for patients with metastatic eyelid sebaceous carcinoma (SC). Programmed death receptor Ligand 1 (PD‐L1) expression and its clinical significance in sebaceous cell carcinoma are presently unknown. This study aimed to evaluate the expression level of PD‐L1 in SC.MethodsThis single centre, retrospective, and comparative study was conducted at the Ninth People's Hospital between August 1, 2013 and September 1, 2016. Twenty primary, 11 recurrent, and 10 lymph node metastatic eyelid SCs of 41 consecutive patients and paired control eyelid samples were enrolled in the study. Immunohistochemical staining of PD‐L1 was performed on slides containing SC embedded in paraffin wax. Patient clinical characteristics and PD‐L1 expression related to SC prognostic values were evaluated.ResultsOf the 41 patients with eyelid SCs, 58.5% (24/41) were female, and 41.5% (17/41) were male. A total of 43.9% (18/41) were left‐sided, and 56.1% (23/41) were right‐sided. A total of 2.4% (1/41) of the SCs were located at the canthus, 51.2% (21/41) were located at the upper eyelid, 41.5% (17/41) were located at the lower eyelids, and 2.4% (1/41) invaded the lacrimal sac. A total of 24.4% of the SCs were metastatic (10/41), 48.8% (20/41) were primary tumours, and 26.8% (11/41) resulted from recurrence. A total of 48.8% (20/41) were moderately graded and 51.2% (21/41) were poorly graded. Programmed death receptor Ligand 1 (PD‐L1) positive expression was found in 20 (48.8%) cases. Programmed death receptor Ligand 1 (PD‐L1) expression was observed on the tumour cell membrane. Higher expression of PD‐L1 was correlated with metastatic cases when compared with primary cases (F = 6.69, p = 0.001). There was a higher expression of PD‐L1 in the poorly differentiated group compared with the moderately graded group (57.1% poorly graded versus 45.0% moderately graded).Conclusion and RelevanceInhibition of PD‐L1 expression may be a therapeutic option for metastatic eyelid SCs, although this hypothesis needs to be tested in future clinical trials.

SummaryBackgroundAlthough current American guidelines distinguish proton pump inhibitor‐responsive oesophageal eosinophilia (PPI‐REE) from eosinophilic oesophagitis (EoE), these entities are broadly similar. While two microarray studies showed that they have similar transcriptomes, more extensive RNA sequencing studies have not been done previously.AimTo determine whether RNA sequencing identifies genetic markers distinguishing PPI‐REE from EoE.MethodsWe retrospectively examined 13 PPI‐REE and 14 EoE biopsies, matched for tissue eosinophil content, and 14 normal controls. Patients and controls were not PPI‐treated at the time of biopsy. We did RNA sequencing on formalin‐fixed, paraffin‐embedded tissue, with differential expression confirmation by quantitative polymerase chain reaction (PCR). We validated the use of formalin‐fixed, paraffin‐embedded vs RNAlater‐preserved tissue, and compared our formalin‐fixed, paraffin‐embedded EoE results to a prior EoE study.ResultsBy RNA sequencing, no genes were differentially expressed between the EoE and PPI‐REE groups at the false discovery rate (FDR) ≤0.01 level. Compared to normal controls, 1996 genes were differentially expressed in the PPI‐REE group and 1306 genes in the EoE group. By less stringent criteria, only MAPK8IP2 was differentially expressed between PPI‐REE and EoE (FDR = 0.029, 2.2‐fold less in EoE than in PPI‐REE), with similar results by PCR. KCNJ2, which was differentially expressed in a prior study, was similar in the EoE and PPI‐REE groups by both RNA sequencing and real‐time PCR.ConclusionEosinophilic oesophagitis and PPI‐REE have comparable transcriptomes, confirming that they are part of the same disease continuum.

AbstractQuestionsWhat are the syntaxonomic and synchorological patterns of the xerothermic chasmophytic vegetation in the central part of the Mediterranean Basin? What are the diagnostic species of the high‐rank syntaxa of Asplenietalia glandulosi, Onosmetalia frutescentis and Centaureo dalmaticae‐Campanuletalia pyramidalis?LocationMediterranean coastal and subcoastal areas of southern France, Italy, Malta, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Albania and of mainland Greece.MethodsThe data set of 1,261 published relevés was analysed using hierarchical clustering (Flexible Beta method), involving a series of data transformations. Indicator species analysis was used to select the best dendrogram solution and identify diagnostic taxa of the main clusters. The dendrogram was interpreted from a syntaxonomic point of view, using nomenclatural type relevés as a basis. The NMDS ordination was performed in order to visualize the floristic relationships among associations and high‐rank syntaxa. MRPP was used to test for differences among alliances.ResultsThe classification revealed four main clusters of relevés representing the chasmophytic vegetation of southern France, Sardinia and the northwestern part of Italy (Asplenienalia glandulosi/Asplenietalia glandulosi), the southwestern part of Italy and Malta (Tinguarrenalia siculae/Asplenietalia glandulosi), the Adriatic Basin area (Centaureo dalmaticae‐Campanuletalia pyramidalis) and the southern Balkans (Onosmetalia frutescentis). The NMDS ordination confirmed the overall pattern, while MRPP showed significant differences among the alliances of the above‐mentioned orders and suborders. The lists of diagnostic taxa of the high‐rank syntaxa were revised according to a supra‐national perspective.ConclusionsThe new syntaxonomic scheme provides a comprehensive overview of the chasmophytic vegetation of the central part of the Mediterranean Basin. This scheme mostly matches the recently published EuroVegChecklist, but also exhibits important novelties concerning the syntaxonomic position of some alliances (Dianthion rupicolae, Centaureion pentadactyli, Arenarion bertolonii and Caro‐Aurinion), and the floristic and chorological relationships among high‐rank syntaxa, with new revised sets of diagnostic taxa. This revision might be useful for further small‐scale phytosociological studies.
The physical and psychological health benefits of positive emotional writing: Investigating the moderating role of Type D (distressed) personality
Authors: Smith Michael A. , Thompson Alexandra , Hall Lynsey J. , Allen Sarah F. , Wetherell Mark A. 
Published: June 2018

ObjectivesType D personality is associated with psychological and physical ill‐health. However, there has been limited investigation of the role of Type D personality in interventions designed to enhance well‐being. This study investigated associations between Type D personality and the efficacy of positive emotional writing for reducing stress, anxiety, and physical symptoms.DesignA between‐subjects longitudinal design was employed.MethodParticipants (N = 71, Mage = 28.2, SDage = 12.4) completed self‐report measures of Type D personality, physical symptoms, perceived stress, and trait anxiety, before completing either (1) positive emotional writing or (2) a non‐emotive control writing task, for 20 min per day over three consecutive days. State anxiety was measured immediately before and after each writing session, and self‐report questionnaires were again administered 4 weeks post‐writing.ResultsParticipants in the positive emotional writing condition showed significantly greater reductions in (1) state anxiety and (2) both trait anxiety and perceived stress over the 4‐week follow‐up period, compared to the control group. While these effects were not moderated by Type D personality, a decrease in trait anxiety was particularly evident in participants who reported both high levels of social inhibition and low negative affectivity. Linguistic analysis of the writing diaries showed that Type D personality was positively associated with swear word use, but not any other linguistic categories.ConclusionThese findings support the efficacy of positive emotional writing for alleviating stress and anxiety, but not perceived physical symptoms. Swearing may be a coping strategy employed by high Type D individuals.
Statement of contribution

What is already known on this subject?

Type D (distressed) personality is characterized by high levels of both negative affectivity and social inhibition, and has been associated with adverse physical and psychological health.

Positive emotional writing is known to reduce subjectively reported physical symptoms and increase positive affect.

What does this study add?

Positive emotional writing was shown to attenuate (1) state anxiety immediately post‐writing, and (2) trait anxiety and perceived stress 4 weeks post‐writing.

The findings demonstrate that positive writing might be a useful intervention for attenuating the adverse psychological effects of Type D personality in the general population.

Type D personality was associated with more frequent use of swear words, which may be a coping mechanism used by high Type D individuals.
Understanding Food System Resilience in Bali, Indonesia: A Moral Economy Approach
Authors: Reuter Thomas 
Published: June 2018

AbstractFood systems in Indonesia and other developing countries have witnessed a rapid change in production, trade, and consumption patterns. The central highlands and northeastern coast of Bali form one such system, with centuries of documented regional trade relations between coastal and highland communities whose food products were complementary. This paper adopts a moral economy approach to explain the decline in local food security at a systemic level, and to explore also how it may be reversed. In particular, I explore how this regional food system operated, and how modernization since the 1990s has compromised biodiversity, ecological sustainability, social resilience, and food security. Greater attention to this moral dimension of food systems, it is argued, will contribute to more successful agricultural development and food security programs.
Age‐related change in brain rhythms from early to middle childhood: Links to executive function
Authors: Perone Sammy , Palanisamy Jeeva , Carlson Stephanie M. 
Published: June 2018

AbstractThe connection between brain rhythms at rest and cognition remains poorly understood. This is especially true during early childhood in which neuroimaging data are relatively scarce. We developed a new method for collecting eyes closed and eyes open resting state electroencephalography (EEG) suitable for young children. We report results characterizing age‐related change in power in multiple brain rhythms over frontal and posterior regions under eyes closed and open conditions of rest in 3‐, 4‐, 5‐ and 9‐year‐old children (N = 162). We observed two key patterns of results. First, with age theta decreased, alpha increased, and alpha peak frequency increased. Second, power was generally higher when eyes were closed than open for theta and alpha but higher when eyes were open than closed for beta and gamma. We also investigated the relation between resting state EEG activity and executive function (EF) using the Minnesota Executive Function Scale, a standardized behavioral measure of EF for ages 2 and up. Correlational and regression analyses showed that individual differences in the theta/beta ratio is associated with EF even after controlling for children's age and verbal abilities. We situate our results in a theoretical discussion of theta/beta and its role in control processes.
