Abstract

Introduction:
One psychosocial factor in the biopsychosocial model is pain-related self-efficacy, which has been shown to be a strong predictor of response to pain treatment.

Objectives:
To cross-culturally adapt the University of Washington Pain-Related Self-Efficacy Scale (UW-PRSE6) into Thai and evaluate its psychometric properties.

Methods:
The study was approved by the Chulalongkorn University Human Ethics Committee (COA No. 156/2018). The original UW-PRSE6 was cross-culturally adapted using the Functional Assessment of Chronic Illness Therapy translation methodology. Two hundred forty-one individuals with chronic low back pain completed the Thai version of UW-PRSE6 (T-UW-PRSE6), Thai Fear Avoidance Beliefs Questionnaire (T-FABQ), and Thai Medical Outcome Study Short-Form 36 (T-SF-36). A subset of 152 participants completed the T-UW-PRSE6 again after a 7-day interval. Cronbach's alpha and intraclass correlation coefficients were calculated to estimate internal consistency and test–retest reliability, respectively. The construct validity of the T-UW-PRSE6 was evaluated by computing Spearman correlation coefficients between the T-UW-PRSE6 score and the measures of the validity criterion variables.

Results:
The T-UW-PRSE6 had good internal consistency (Cronbach's alpha = 0.85) and moderate test–retest reliability (intraclass correlation coefficient [2,1] = 0.72). The T-UW-PRSE6 was negatively correlated with the T-FABQ Work and Physical Activity subscales (rs = −0.34 and −0.34, respectively) and positively correlated with the General Health, Physical Functioning, Role Physical, Role Emotional, Social Functioning, Bodily Pain, Vitality, and Mental Health scales of the T-SF-36 (rs = 0.38, 0.42, 0.54, 0.51, 0.47, 0.54, 0.41, and 0.40, respectively).

Conclusion:
The T-UW-PRSE6 demonstrated acceptable psychometric properties for assessing pain-related self-efficacy in individuals with chronic low back pain, making available a measure for facilitating future cross-cultural research on pain self-efficacy.

Abstract

Introduction:
In Brazil, the prevalence and costs of pain will increase substantially with population ageing. Understanding of pain epidemiology is needed for the development of health care policies that can minimize this projected burden.

Objective:
To investigate the prevalence of pain and associated factors at baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods:
Data were collected in public institutions of higher education/research (2008–2010). Pain in the past 30 days and pain attributed to psychological distress (“with psychological attributions”—PPA) were evaluated by the Clinical Interview Schedule-Revised (CIS-R). The independent t-test and χ2 test investigated associations between sociodemographic/clinical factors and each pain episode. Multivariable analyses including age, sex, leisure-time physical activity, depression, and arthritis/rheumatism, and factors showing univariate associations at the P < 0.10 level, were performed.

Results:
Fifteen thousand ninety-five civil servants were included (52.1 ± 9.1 years, 54.4% female). The prevalence of any pain was 62.4% (95% confidence interval 61.6%–63.2%), and of PPA was 22.8% (95% confidence interval 22.2%–23.5%). Factors associated with any pain and PPA in multivariable analyses included age (odds ratio [OR] 0.97), female sex (OR 1.86–2.01), moderate and vigorous leisure-time physical activity (OR 0.60–0.84), excessive drinking (OR 0.68–0.83), depressive symptoms (OR 1.28–1.96), anxiety symptoms (OR 1.63–2.45), sleep disturbance (OR 1.62–1.79), and arthritis/rheumatism (OR 1.32–2.18). Nonroutine nonmanual occupation (manual occupation as reference), body mass index, and smoking were independently associated with either any pain or PPA.

Conclusion:
This study provided preliminary information on the epidemiology of pain at baseline of the largest Latin American cohort on chronic noncommunicable diseases.

Authors: Silveri Maria Caterina , Di Tella Sonia , Magni Eugenio , Pepe Fulvio , Leone Edoardo , Piludu Francesca , Colosimo Cesare , Ciccarelli Nicoletta 
Published: December 2019

Objective:
To investigate whether the characteristics of language disorders of degenerative and vascular aphasias depend on the underlying neuropathology.

Methods:
Logopenic variant/mixed primary progressive aphasics (lvmPPA; n=18) and poststroke fluent aphasics (PSA; n=11) underwent a neuropsychological examination and an assessment of the macro- and microlinguistic aspects of language. A principal component analysis and a cluster analysis applying a two-group solution were performed on the scores obtained from the neuropsychological and language examination.

Results:
Global cognition, lexical-semantic, and morphosyntactic components, and two components loading macrolinguistic variables, were extracted by the principal component analysis. A first cluster of 18 participants (14 lvmPPA and 4 PSA) and a second cluster of 11 participants (4 lvmPPA and 7 PSA) were identified. Participants in the first cluster were significantly more impaired than those in the second cluster in global cognition, lexical-semantic, and morphosyntactic components. Macrolinguistic components did not differentiate the two clusters. lvmPPA in the first cluster showed bilateral cortical thinning (greater on the left), whereas lvmPPA in the second cluster showed atrophy only in the left. Participants with PSA in both clusters showed vascular lesions encompassing the posterior left perisylvian regions. Underestimation of the severity of the leukoencephalopathy and damage of the interhemispheric connectivity might be responsible for the inclusion of PSA individuals in the first cluster, despite a unilateral lesion.

Conclusions:
Lesion localization is the main factor that determines the characteristics of aphasic deficits. Etiology indirectly acts through a different sensitivity of the brain regions to various pathologies.

Published: December 2019

Purpose:
In adults, central fast-frequency sleep spindles are involved in learning and memory functions. The density of local spindles is higher than global spindles, emphasizing the importance of local plastic neural processes. In children, findings on the association of spindles with cognition are more variable. Hence, we aim to study whether the local spindles are also important for neurobehavioral performance in children.

Methods:
We studied the correlations between local (occurring in only one channel: Fp1, Fp2, C3, or C4), bilateral, and diffuse (occurring in all four channels) spindles and neurobehavioral performance in 17 healthy children (median age 9.6 years).

Results:
Local spindles were not as frequent as bilateral spindles (P-values < 0.05). Central spindle types had significant correlations with sensorimotor and language functions (e.g., the density of bilateral central spindles correlated positively with the Object Assembly in NEPSY, r = 0.490). Interestingly, frontopolar spindles correlated with behavior (e.g., the more bilateral the frontopolar spindles, the less hyperactive the children, r = −0.618).

Conclusions:
In children, the local spindles, but also more widespread central spindles, seem to be involved in the cognitive processes. Based on our findings, it is important that ageadjusted frequency limits are used in studies evaluating the frequencies of spindles in children.

Published: December 2019

PURPOSE:The purpose of this quality improvement project was to design and validate a multimedia educational software program for patients with fecal diversions.PARTICIPANTS AND SETTING:Ten individuals who had fecal diversion surgery and 10 experts including nurses, physicians, nutritionists, and information technologists from Imam Khomeini and Rasule Akram Hospitals, Tehran, Iran, the 2 main centers in which fecal diversion surgery took place, were included in the study.APPROACH:The multimedia educational software for patients with ostomy was developed in 3 phases including development and creation, validity, and modification of the software. Data for phase 1 were collected using 2 questionnaires, the Multimedia Survey Questionnaire for Clients and the Multimedia Survey Questionnaire for Experts, and several open-ended questions to further determine the content and face validity of the multimedia content for the education prototype.OUTCOMES:The mean ± standard deviation [SD] of multimedia evaluation by the 10 patients was 60 ± 3.27, indicating high user satisfaction. The mean ± SD of multimedia evaluation by the 10 experts was 171.1 ± 19.2, suggesting the content was of high quality. Content and face validity were reported to be 0.91 and 0.96, respectively. The program was then created and called “Self-Care of Ostomy,” which consisted of 8 computer-based modules with 22 short videos and slide presentations available for viewing by patients with newly created ostomies.IMPLICATIONS FOR PRACTICE:This multimedia program can provide patients with simple, portable, understandable, objective, user-friendly information about ostomy care. Future studies should address the effectiveness of ostomy management among patients, families, and care providers.
Bespoke extensional elasticity through helical lattice systems

Published: December 2019

Nonlinear structural behaviour offers a richness of response that cannot be replicated within a traditional linear design paradigm. However, designing robust and reliable nonlinearity remains a challenge, in part, due to the difficulty in describing the behaviour of nonlinear systems in an intuitive manner. Here, we present an approach that overcomes this difficulty by constructing an effectively one-dimensional system that can be tuned to produce bespoke nonlinear responses in a systematic and understandable manner. Specifically, given a continuous energy function E and a tolerance
ϵ
> 0, we construct a system whose energy is approximately E up to an additive constant, with L
∞
-error no more that
ϵ
. The system is composed of helical lattices that act as one-dimensional nonlinear springs in parallel. We demonstrate that the energy of the system can approximate any polynomial and, thus, by Weierstrass approximation theorem, any continuous function. We implement an algorithm to tune the geometry, stiffness and pre-strain of each lattice to obtain the desired system behaviour systematically. Examples are provided to show the richness of the design space and highlight how the system can exhibit increasingly complex behaviours including tailored deformation-dependent stiffness, snap-through buckling and multi-stability.
Syncytium cell growth increases IK1 contribution in human iPS-cardiomyocytes
Authors: Li Weizhen , Entcheva Emilia 
Published: December 2019

SummaryHuman induced pluripotent stem-cell-derived cardiomyocytes (hiPS-CMs) enable cardiotoxicity testing and personalized medicine. However, their maturity is of concern, including relatively depolarized resting membrane potential and more spontaneous activity compared to adult cardiomyocytes, implicating low or lacking inward-rectifier potassium current (Ik1). Here, protein quantification confirms Ik1 expression in hiPS-CM syncytia, albeit several times lower than in adult heart tissue. We find that hiPS-CM cell culture density influences Ik1 expression and the associated electrophysiology phenotype. All-optical cardiac electrophysiology and pharmacological treatments reveal reduction of spontaneous and irregular activity in denser cultures. Blocking Ik1 with BaCl2 increased spontaneous frequency and blunted action potential upstrokes during pacing in a dose-dependent manner only in the highest-density cultures, in line with Ik1’s role in regulating the resting membrane potential. Our results emphasize the importance of syncytial growth of hiPS-CM for more physiologically-relevant phenotype and the power of all-optical electrophysiology to study cardiomyocytes in their multicellular setting.

AbstractINTRODUCTIONKnowledge of the epidemiology of plasmids is essential for understanding the evolution and spread of antimicrobial resistance. PlasmidSPAdes attempts to reconstruct plasmids using short-read sequence data. Accurate detection of extended-spectrum beta-lactamase (ESBL) genes and plasmid replicon genes is a prerequisite for the use of plasmid assembly tools to investigate the role of plasmids in the spread and evolution of ESBL production in Enterobacteriaceae. This study evaluated the performance of PlasmidSPAdes plasmid assembly for Enterobacteriaceae in terms of detection of ESBL-encoding genes, plasmid replicons and chromosomal genes, and assessed the effect of k-mer size.METHODSShort-read sequence data of 59 ESBL-producing Enterobacteriaceae were assembled with PlasmidSPAdes using different k-mer sizes (21, 33, 55, 77, 99 and 127). For every k-mer size, the presence of ESBL genes, plasmid replicons and a selection of chromosomal genes in the plasmid assembly was determined.RESULTSOut of 241 plasmid replicons and 66 ESBL genes detected by whole-genome assemblies, 213 plasmid replicons (88%; 95% Confidence Interval (CI): 83.9-91.9) and 43 ESBL genes (65%; 95%CI: 53.1-75.6) were detected in the plasmid assemblies obtained by PlasmidSPAdes. For most ESBL genes (83.3%) and plasmid replicons (72.0%), detection results did not differ between the k-mer sizes used in the plasmid assembly. No optimal k-mer size could be defined for the number of ESBL genes and plasmid replicons detected. For most isolates, the number of chromosomal genes detected in the plasmid assemblies decreased with increasing k-mer size.CONCLUSIONBased on our findings, PlasmidSPAdes is not a suitable plasmid assembly tool for short-read sequence data of ESBL-encoding plasmids of Enterobacteriaceae.

Published: December 2019

ABSTRACTThe ecological impacts of extreme climatic events on population dynamics and/or community composition are profound and predominantly negative. Here, using extensive data of an ecological model system, we test whether predictions from ecological models remain robust when environmental conditions are outside the bounds of observation. First, we report a 10-fold demographic decline of the Glanville fritillary butterfly metapopulation on the Åland islands (Finland). Next, using climatic and satellite data we show that the summer of 2018 was an anomaly in terms of water balance and vegetation productivity indices across the habitats of the butterfly, and demonstrate that population growth rates are strongly associated with spatio-temporal variation in climatic water balance. Finally, we demonstrate that covariates that have previously been identified to impact the extinction probability of local populations in this system are less informative when populations are exposed to (severe) drought during the summer months. Our results highlight the unpredictable responses of natural populations to extreme climatic events.
R&D volatility and market value: the role of executive overconfidence
Authors: Hai Benlu , Gao Qingzhu , Yin Ximing , Chen Jin 
Published: December 2019

Purpose
Significant increase or decrease in research and development (R&D) expenditure may have an immense impact on market value. Based on the punctuated equilibrium theory, this paper aims to empirically analyze the impact of R&D volatilities on market value and the moderating effect of executive overconfidence.

Design/methodology/approach
The study uses the panel data set that covers 902 Shanghai and Shenzhen A-share manufacturing listed firms and multiple regression method to test the theoretical hypotheses.

Findings
The results show that both positive and negative R&D volatilities have a robust and significant positive impact on the market value. Further analysis shows that the executive overconfidence positively moderates the relationship between R&D volatilities and market value.

Research limitations/implications
In a rapidly changing and highly competitive environment, firms should recognize that the balance of innovation strategies will help to bring higher market value. Furthermore, firms could improve corporate governance to make the best of managerial characteristics, such as overconfidence, on the innovation decision-making process.

Originality/value
By pushing the static perspective to a dynamic perspective and empirically documenting the role of executive overconfidence, this study contributes to the literature on the relationship between R&D expenditure and market value, generating theoretical and practical insights for firms to improve innovation governance and innovation strategies to achieve better business performance.

Exploring bullying among Indian managers: a grounded theory approach
Authors: Agarwal Upasna A. , Rai Arpana 
Published: December 2019

PurposeThis paper aims to explore the phenomenon of workplace bullying – its nature, antecedents, direct and indirect effects – from victim’s perspective.Design/methodology/approachThe study adopted grounded theory approach and centered on the participants experiences and interpretations of bullying. A total of 23 self-reported victims formed the sample of our study. Data from interviews were analyzed using the coding procedure of grounded theory methodology. To enhance validity of results, in addition to interviews, creative drawings were used for triangulation.FindingsThe study reveals some similarities and culturally relevant variation in the sources and outcomes of bullying. The role of culture on bullying is visible. The study also adds to the limited literature on underlying and intervening factors in bullying–outcome relationship.Research limitations/implicationsThe study examined bullying from the victim’s perspective. Perpetrator and bystander’s perspectives would have added interesting insights into the findings.Practical implicationsEffective identification of, prevention of and intervention in workplace bullying are imperative for individuals and organizations. Rich descriptions from victims on enablers of bullying and how these events have affected their everyday experiences may also boost practitioners’ and policymakers’ willingness to rectify the potential issues leading to bullying in organizations.Originality/valueThe present study contributes to the workplace bullying research in general and Indian context in particular by examining contextually relevant antecedents, consequences as well as underlying and intervening factors.
Do female and male entrepreneurs differ in their proneness to heuristics and biases?
Authors: Nouri Pouria , AhmadiKafeshani Abdollah 
Published: December 2019

PurposeAlthough heuristics and biases seal the fate of entrepreneurial enterprises by directly influencing entrepreneurs’ decisions, previous studies have ignored the role of gender in this regard by considering female and male entrepreneurs homogeneous in their susceptibility to heuristics and biases. Thus, this paper aims to advance the existing body of knowledge on heuristics and biases in the field of entrepreneurship by exploring two heuristics of affect and representativeness as well as three biases of overconfidence, escalation of commitment and illusion of control in female and male entrepreneurs’ entry and opportunity-related decisions.Design/methodology/approachThe data were gathered through semi-structured and in-depth interviews with ten male and nine female Iranian techno-entrepreneurs active in advanced medicine and biotechnology. The gathered data were analyzed by thematic and narrative data analysis.FindingsAccording to the results, while both male and female entrepreneurs show certain heuristics and biases, there are some noteworthy distinctions. More precisely, contrary to their male counterparts, the female entrepreneurs neither rely on the representativeness heuristic nor show any signs of the escalation of commitment in their decisions.Practical implicationsThere are some valuable implications emanated from this study which could be of use for not only future researchers but also entrepreneurs, especially the ones founding and running small businesses themselves.Originality/valueWhile there is a strong body of literature on heuristics and biases in the field of entrepreneurship, previous studies have considered female and male entrepreneurs homogeneous in their proneness to heuristics and biases. Thus, the current study enriches the body of knowledge by being the first comparative study of heuristics and biases in female and male entrepreneurs’ decisions.
