Published: December 2019

Purpose
The purpose of this paper is to analyze job-related stress, motivation and satisfaction in higher education institutions, and assesses their implications on health in various industries including higher education. In total, 52 higher education faculty and administrators from institutions in more than 16 countries participated in the study that utilized the organizational surveys, Organizational Effectiveness Inventory® from human synergistics. Subgroup analysis was done to compare faculty and administrators; males to females, private, public, for-profit and not-for-profit institutions.

Design/methodology/approach
To assess health implications, 160 respondents employed in seven industries were surveyed using a custom medical/stress questionnaire to collect self-reported data on levels of job-related stress, motivation and satisfaction as well as the presence of several medical conditions, including myocardial infarction, stroke, angina pectoris/coronary heart disease, hypertension, gastro-esophageal reflux disease and diabetes mellitus. The results from each of the two surveys were statistically analyzed separately.

Findings
Results show undesirable levels of job-related stress, motivation and satisfaction in some segments of higher education employees; as well as associations between poorer health and high stress levels. The study established a potential justification consequently, the authors recommend organizational offerings of: stress relief programs; health fairs and health club memberships; stress management workshops; use of mobile apps for stress relief; job description reviews to eliminate work-related demands; changes to managerial styles that align with the culture of employees; re-evaluation of organizational structure; and enhanced communication amongst workplace management and employees.

Research limitations/implications
Limitations of this study include small sample sizes and the presence of confounding factors that were not considered. In addition, this study did not look into whether occupational position or occupational difficulty compromised the nature of work causing employees to experience lower levels of satisfaction, since the extent to which employees feel satisfied with their work may influence their physical well-being.

Originality/value
There are a number of factors that can affect employees with regards to medical illnesses in a job-related setting. There are three factors in particular that have been shown to negatively affect the health of employees: job-related stress; motivation; and satisfaction. These effects have not been studied in depth in faculty and administrators of higher education institutions, hence this study seeks to achieve that.
The trickle-down effect of OCB in schools: the link between leader OCB and team OCB
Authors: Somech Anit , Ohayon Bat-El 
Published: December 2019

PurposeResearch has provided accumulative evidence that the willingness of teachers to invest in organizational citizenship behavior (OCB) is a fundamental component for achieving school effectiveness. However, most studies examined OCB of the individual teacher, while neglecting the fact that such behavior might grow in a context. Furthermore, educational scholars have focused almost solely on OCB of teachers, and have almost completely neglected to address the concept through a managerial prism. By taking a contextual perspective, the purpose of this paper is to postulate a positive link between leader OCB and team OCB, and suggest that organizational justice serves as a moderator in this relationship.Design/methodology/approachData were collected through a survey from multiple sources, to avoid one-source bias. The sample included 82 schools: 82 management teams and their 82 principals, as well as 246 teachers, who were not members of management.FindingsResults of the hierarchical regression analysis confirmed the hypotheses. The authors found a positive association between leader OCB and team OCB and revealed that this positive relationship was significant under high levels of organizational justice, but non-significant under low levels.Practical implicationsThe importance of leader OCB in promoting team OCB can inspire the educational system to learn how to develop organizational mechanisms that encourage principals to perform citizenship behaviors and to take this component into consideration in screening processes and succession planning.Originality/valueThe contribution of the study is in identifying leader OCB as a key instrument that may encourage teams to invest in OCBs. To the best of the authors’ knowledge, this is the first study ever to examine the link between leader OCB and team OCB. The finding that there is a positive association between the two constructs may imply that leader OCBs contribute to the school, not only directly, by exhibiting behaviors of helping and support, but also indirectly, through the leader’s impact on his or her team’s behavior.
Cost, revenue, and profit efficiency characteristics, and intellectual capital in Indian Banks
Authors: Vidyarthi Harishankar , Tiwari Ranjit 
Published: December 2019

PurposeThe purpose of this paper is to estimate the economic (namely cost, revenue and profit) efficiency and its association with intellectual capital of 37 BSE-listed Indian banks over the period 2005–2018.Design/methodology/approachThis study employs truncated Tobit regression to compute the relationship between intellectual capital and estimated cost, revenue and profit efficiency using Data Envelopment Analysis (DEA) for the 37 BSE-listed Indian banks within the panel data framework.FindingsEstimates suggest that banks’ overall annual average cost, revenue and profit efficiency are 0.4466–0.7519, 0.4825–0.8773 and 0.4905–0.8803, respectively, during the sample period. Further, Tobit regression results indicate that the aggregate intellectual capital (value-added intellectual coefficient or Modified Value-added Intellectual Capital) has a positive but minimal impact on these efficiency parameters at 1 percent significance level for the overall sample as well as public sector banks. Among all the sub-components of intellectual capital, human capital, structural capital and relational capital have a positive and moderate impact on these efficiency measures for the overall sample. Control variables, particularly bank size, are significant drivers of the estimated efficiency of banks.Research limitations/implicationsFindings suggest that banks should invest adequately to enhance their overall intellectual capital to further augment these economic efficiency measures in the long run.Originality/valueThis study computes cost, revenue and profit efficiency of 37 BSE-listed banks based on DEA followed by intellectual capital using the Pulic approach (1998 and 2000) and the Bontis (1998) approach in the first stage. Later, it examines the dynamics between the computed efficiency parameters and intellectual capital using Tobit regression within the panel data framework.
Ketamine inhibits aerobic glycolysis in colorectal cancer cells by blocking the NMDA receptor‐CaMK II‐c‐Myc pathway

Published: December 2019

AbstractAerobic glycolysis plays a crucial role in cancer progression. Ketamine is often used for cancer pain relief in clinical settings. Moreover, ketamine inhibits proliferation and induces apoptosis in many cancer cell types. However, the anti‐tumour mechanism of ketamine is still poorly understood. In the present study, we survey whether and how ketamine inhibits aerobic glycolysis in colon cancer cells. Glycolysis of colon cancer cells was determined by detecting the extracellular acidification rate in HT29 and SW480 cells. Quantitative real‐time PCR was employed to determine mRNA expression. Calcium levels were detected with a Fluo‐3 AM fluorescence kit. Micro‐positron emission tomography/computed tomography (microPET/CT) imaging was employed to assess glycolysis in the tumours of the xenograft model. Ketamine treatment inhibited colon cancer cell viability and migration in HT29 and SW480 cells. Moreover, ketamine decreased aerobic glycolysis and decreased the expression of glycolysis‐related proteins in HT29 and SW480 cells. MicroPET/CT demonstrated that ketamine decreased 18F‐FDG uptake in the xenograft model. In addition, ketamine inhibited c‐Myc expression and CaMK II phosphorylation and decreased calcium levels. Further, dizocilpine (an NMDAR inhibitor), and KN93 (a CaMK II inhibitor), decreased CaMK II phosphorylation, c‐Myc expression, and cancer cell glycolysis; these results were similar to those with ketamine treatment. Furthermore, the anti‐tumour effect of ketamine was counteracted by rapastinel (an NMDAR activator). Ketamine inhibited aerobic glycolysis in colon cancer cells probably by blocking the NMDA receptor‐CaMK II‐c‐Myc pathway, thus attenuating colon cancer cell viability and migration.
“Damned if you do, damned if you don’t”: Media frames of responsibility and accountability in handling a wildfire
Authors: Nilsson Sofia , Enander Ann 
Published: December 2019

AbstractPrevious research on media framing of wildfire has chiefly been concerned with the nature of wildfire in the context of climate change and with framing effects on policy and public opinion. Empirical studies on media content, hence what is mediated to crisis managers and the public concerning authorities’ and the public's response, seem to be largely missing. This is remarkable, given that the media represent main sources of information that may influence crisis management and shape public opinion. Thus, the aim of this study was to identify key media frames relating to portrayals of public and authority responses during and after a wildfire crisis. The study is based on media articles from two time periods: immediately after the fire and 1 year later. We used a thematic method of analysis (TA), thus an inductive, “bottom‐up” approach. A core frame, Responsibility/accountability is identified, underpinned by two sub‐themes. One sub‐theme relates to the causes of the fire and its escalation, revealing a number of different interrelated blame frames. The second sub‐theme refers to management of the crisis, reflecting both authorities’ and citizens’ responses. The deficiencies of the former are implicitly suggested to have forced citizens to act to compensate for their inadequacy. The main theoretical contribution is the identification of an interrelationship between frames in relation to different groups of individuals responding to a crisis, pointing to a more complex view of framing effects. In addition, results show how media tend to assess crisis management based on idealistic criteria, inevitably making the evaluation negative. This contributes to an understanding of how media blame frames, thus “blame games,” may unfold. Practical implications of these results are discussed.

Published: December 2019

AbstractIn this study, we analysed a total of 16 libraries from over 150 grapevine leaf and grape samples infected with Plasmopara viticola (downy mildew of grapevine) to characterise the virome associated to this oomycete. Samples were collected in five distinct regions in Italy and in four different regions in Spain, representative of different pedoclimatic conditions and different grapevine cultivars during 2018 growing season. Due to the metagenomics nature of the samples (containing at least both downy mildew hyphae and spores, and grapevine cells residues), we were able to assemble several plant viruses and a few possible novel plant virus genomes with our in silico analysis. We detected several plant virus variants already reported in grapevine, and a putative new ilarvirus previously unreported in grapevine. Furthermore, we characterised three new phenui‐like viruses (in the order Bunyavirales), one of which shares some commonalities with plant coguviruses. Finally, we report a new strict association of three viral segments (one flavi‐like and two virga‐like) that we propose to be a new virus taxon named jivivirus.

Published: December 2019

BackgroundPerioperative blood loss is a major contributor to morbidity and mortality in cardiac surgery. Plasma fibrinogen levels play an essential role in hemostasis and deplete quickly during hemorrhage. The objective of this study was to determine whether prophylactic fibrinogen concentrate administration lowers overall blood product transfusion requirements in high‐risk cardiac surgery in patients with low fibrinogen plasma levels.MethodsThe study was performed in a prospective, randomized, and double‐blinded design. The investigation included 62 patients undergoing elective, high‐risk cardiac surgery. After weaning from cardiopulmonary bypass and reversal of heparin patients received either fibrinogen concentrate or placebo. The primary outcome variable was overall blood product usage 24 hours after intervention.ResultsThe fibrinogen group received numerically fewer total units of blood products than the placebo group, but the difference was not statistically or clinically significant (for groups n = 27; n = 29 and 19 vs 37 units, respectively, P = .908). The overall transfusion rate in both groups was significantly lower than the institutional average suggested (fibrinogen group 26%, placebo group 28%). The fibrinogen group showed significantly higher fibrinogen levels (2.38 vs 1.83 g/L (end of surgery), P < .001; 3.33 vs 2.68 g/L (12 hours after intervention), P = .003) and improved viscoelastic coagulation parameters (FIBTEM MCF, 27 vs 23 mm, P = .022).ConclusionThis randomized, controlled trial demonstrates that point‐of‐care guided and prophylactic treatment with fibrinogen concentrate does not reduce transfusion of blood products in a setting of unexpectedly low transfusion rate as tested in this cohort, but may improve coagulation parameters in the setting of high‐risk cardiac surgery.

Published: December 2019

BackgroundHigh body mass index (BMI) can predict difficult neuraxial block; however, fat distribution may also be important. The primary study aim was to identify body habitus and fat distribution measurements that correlated with ultrasound measured epidural depth. We hypothesized that measurements such as midarm and subscapular fatpad thicknesses and length of cervical spine may correlate better with ultrasound measured epidural depth than a global measure of BMI.MethodsProspective IRB approved study of term pregnant women requiring neuraxial block. We measured height, weight (BMI, kg/m2), subscapular, midarm fatpad thickness (digital caliper, mm), vertebral column length (C7 to sacral hiatus, cm) and epidural depth (ultrasound, mm). Four experts assessed photographs to assign anticipated difficult neuraxial block in sitting and lateral positions (5‐point Likert scale, 1 = very easy, 5 = very difficult).ResultsIn all, 131 women completed body habitus measurements. Measured mean (standard deviation) BMI was 30.3 (5.4) kg/m2. Measured BMI, subscapular fatpad and midarm fatpad thickness were significantly correlated with ultrasound depth to epidural space (R2 0.733, 0.626 and 0.633, respectively, P < .0001) but vertebral column length was not. The experts had a high level of agreement (Cronbach's alpha >0.7) for assessment of anticipated difficult block in the sitting and lateral positions; however, anticipated difficult block was not correlated with epidural depth measured by ultrasound for sitting position, R2 = −0.015, P = .87; and lateral position, R2 = −0.087, P = .33.ConclusionsMeasurements of body habitus and fat distribution were no better than measured BMI to anticipate greater ultrasound measured depth to epidural space.Clinical trial number: Non‐interventional observational study, not registered.
Raciontologies: Rethinking Anthropological Accounts of Institutional Racism and Enactments of White Supremacy in the United States
Authors: Rosa Jonathan , Díaz Vanessa 
Published: December 2019

ABSTRACTThis article presents a theory of raciontologies—the fundamentally racialized grounding of various states of being—that sheds light on complex forms of institutional racism and white supremacy. We are interested in exploring not only how institutional contexts and processes function as sites or vehicles for the reproduction of white supremacy but more specifically how institutions become endowed with the capacity to act in their own right. This approach represents a raciontological perspective that attends to the central role that race plays in constituting modern subjects and objects in relation to particular states of being. Raciolontologies powerfully shape how entities become endowed with the capacity to engage in particular acts, while also conditioning perceptions, experiences, and material groundings of reality. Our theorization of raciontologies combines anthropological analyses of institutional racism and ontologies beyond the human. These analyses point to the role of institutions in the reproduction of white supremacy and reimagine the range of entities capable of action, respectively. The broader goal is to suggest how new ways of understanding the raciontological nature of institutional enactments of white supremacy can inform antiracist theories of change.

AbstractIntroductionThe levonorgestrel intrauterine system (LNG‐IUS) is a long‐acting hormone‐releasing uterine device that has many non‐contraceptive benefits. The study aims to assess the safety and efficacy of LNG‐IUS in the management of adenomyosis.Material and methodsWe searched the following bibliographic databases: MEDLINE via PubMed, SCOPUS, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and Google Scholar for the relevant studies which used LNG‐IUS in management of patients with clinically or ultrasonographic diagnosed adenomyosis.The main outcome measures are pain score at the end of follow‐up, bleeding, symptomatic relief, uterine volume (mL), endometrial thickness (mm) and/or hemoglobin level.ResultsTen prospective studies (patients n = 551) were included. The overall effect estimates showed that the LNG‐IUS led to significant reductions in pain score after 12 months (standardized mean difference [SMD[ −3.87, 95% confidence interval [CI] −5.51 to −2.23, P < .001), 24 months (SMD −5.56, 95% CI −9.80 to −1.32, P = .01) and 36 months of insertion (SMD −3.81, 95% CI −4.27 to −3.36, P < .001). Similarly, the Pictorial Blood Assessment Chart (PBAC) showed significant reduction up to 36 months after LNG‐IUS insertion (SMD −2.32, 95% CI −2.91 to −1.73, P < .001). The LNG‐IUS led to significant reductions in the uterine volume 12 months (SMD −.60, 95% CI −0.88 to −.31, P < .001) and 36 months after insertion (SMD −0.42, 95% CI −0.69 to −0.14, P = .003).ConclusionsLNG‐IUS is a promising and effective option for the management of adenomyosis. Its use effectively reduced the severity of symptoms, uterine volume and endometrial thickness, and improved laboratory outcomes.

AbstractIntroductionMajor depressive disorder (MDD) is one of the most common mental disorders worldwide. The aim of this study was to identify potential pathological genes in MDD.MethodsWe searched and downloaded gene expression data from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) in MDD. Then, Kyoto Encyclopedia of Genes and Genomes pathway, Gene Ontology analysis, and protein‐protein interaction (PPI) network were applied to investigate the biological function of identified DEGs. The quantitative real‐time polymerase chain reaction and a published dataset were used to validate the result of bioinformatics analysis.ResultsA total of 514 DEGs were identified in MDD. In the PPI network, some hub genes with high degrees were identified, such as EEF2, RPL26L1, RPLP0, PRPF8, LSM3, DHX9, RSRC1, and AP2B1. The result of in vitro validation of RPL26L1, RSRC1, TOMM20L, RPLPO, PRPF8, AP2B1, STIP1, and C5orf45 was consistent with the bioinformatics analysis. Electronic validation of C5orf45, STIP1, PRPF8, AP2B1, and SLC35E1 was consistent with the bioinformatics analysis.DiscussionThe deregulated genes could be used as potential pathological factors of MDD. In addition, EEF2, RPL26L1, RPLP0, PRPF8, LSM3, DHX9, RSRC1, and AP2B1 might be therapeutic targets for MDD.
Environmental correlates of leguminosae species richness in Mexico: Quantifying the contributions of energy and environmental seasonality

Published: December 2019

AbstractExplaining species richness patterns is a central issue in ecology, but a general explanation remains elusive. Environmental conditions have been proposed to be important drivers of these patterns, but we still need to better understand the relative contribution of environmental factors. Here, we aim at testing two environmental hypotheses for richness gradients: energy availability and environmental seasonality using diversity patterns of the family Leguminosae across Mexico. We compiled a data base of 502 species and 32,962 records. After dividing Mexico into 100 × 100 km grid cells, we constructed a map of variation in species richness that accounts for heterogeneity in sampling effort. We found the cells with the highest species richness of legumes are in the Neotropical region of Pacific coastal and southern Mexico, where the legume family dominates the tropical rain forests and seasonally dry tropical forests. Regression models show that energy and seasonality predictors can explain 25% and 49% of the variation in richness, respectively. Spatial autocorrelation analysis showed that richness has a strong spatial structure, but that most of this structure disappears when both energy and seasonality are used to account for richness gradient. Our study demonstrates multiple environmental conditions contribute complementarily to explain diversity gradients. Moreover, it shows that in some regions, environmental seasonality can be more important than energy availability, contradicting studies at coarser spatial scales. More basic taxonomic and floristic work is needed to help describe patterns of diversity for many groups to allow for testing the underlying mechanisms responsible for diversity gradients.Abstract in Spanish is available with online material.
