The Psychometric Properties of the Persian Version of the COVID-19 Burnout Scale

Background: Because of the long duration of the coronavirus disease 2019 (COVID-19) pandemic, people may suffer greatly from the common burnout caused by this virus. Objectives: Considering the psychological consequences of COVID-19, this study investigated the validity and reliability of the Persian version of the COVID-19 Burnout Scale (COVID-19-BS). Methods: The Persian version of the COVID-19-BS was prepared through forward translation, reconciliation, and back-translation. The method of the study was descriptive (psychometric). The statistical population included all students of Ahvaz Jundishapur University of Medical Sciences, Iran, from October 2020 to October 2021. Using the convenience sampling method, 251 students were selected. All participants completed the COVID-19 Anxiety Syndrome Scale (C-19ASS), the Compassion Scale (CS), and the COVID-19-BS. Convergent validity, divergent validity, and confirmatory factor analysis (CFA) were used to evaluate the validity. Data analysis was performed using SPSS version 25 and LISREL 8.5 software. Results: The findings supported the single-factor structure of COVID-19-BS and a good internal consistency of the scale. Internal consistency obtained by Cronbach’s alpha method for the total score of C-19ASS was 0.72, indicating a good internal consistency. The COVID-19-BS had a positive and significant correlation with the C-19ASS (P = 0.01, r = 0.37) and a negative and significant correlation with the CS (P = 0.01, r = -0.41), indicating the convergent and divergent validity of this scale (P
Influence of occupants' knowledge on comfort expectations and behaviour

What influence does ‘knowledge’ exert on occupant behaviour and comfort? What is the nature of the gap between the assumed and the actual behaviour of occupants in green buildings? To address these questions, two buildings – one conventional and the other green – located at the University of British Columbia in Vancouver, BC, Canada – are examined. Results from a comparative post-occupancy evaluation show that while the availability and use of personal controls was higher in the green building, the quality of personal control in terms of responsiveness, the absence of immediate and relevant feedback, and poor user comprehension may have led to sub-optimal comfort conditions. The findings suggest a desire on the part of users to learn more about how buildings work and comfort is provided, with a higher interest level in the green building over the conventionally designed. However, the relationship between knowledge, personal controls, and comfort was found to be more complex. While knowledge of the building was positively related to use of personal control in the green building, neither knowledge nor personal control use resulted in higher overall perceived comfort. Quelle influence les « connaissances » exercent-elles sur le comportement et le confort des occupants ? Quelle est la nature de l'écart existant entre le comportement supposé et le comportement réel des occupants dans les bâtiments verts ? Pour aborder ces questions, deux bâtiments – l'un classique et l'autre vert – situés sur l'Université de Colombie Britannique à Vancouver, CB, au Canada, ont été étudiés. Les résultats d'une évaluation comparative après occupation des lieux montrent que, alors qu'il y avait une plus grande disponibilité et utilisation des commandes individuelles dans le bâtiment vert, la qualité des commandes individuelles en termes de réactivité, l'absence de feedback immédiat et pertinent, et une mauvaise compréhension de la part des utilisateurs peuvent avoir conduit à des conditions de confort suboptimales. Les conclusions suggèrent un désir de la part des utilisateurs d'en apprendre davantage sur la manière dont les bâtiments fonctionnent et dont le confort est assuré, avec un niveau d'intérêt plus important dans le bâtiment vert que dans celui de conception classique. Néanmoins, il a été constaté que les relations entre les connaissances, les commandes individuelles et le confort étaient d'une plus grande complexité. Alors que les connaissances relatives au bâtiment étaient positivement liées à l'utilisation des commandes individuelles dans le bâtiment vert, ni les connaissances, ni l'utilisation des commandes individuelles n'ont entraîné la perception d'un plus grand confort global.

Neuropsychological Profile in Pediatric Migraine without Aura: A Pilot Study

Despite the high prevalence of headache in developmental age, current reports about its neuropsychological effects are still lacking. The aim of the present pilot study is to assess the neuropsychological skills among children affected by migraine without aura (MwoA). Fifteen children (7M/8F) (mean age 10.73 ± 2.13) with MwoA, consecutively referred to the Center for Childhood Headache at Università degli Studi della Campania “Luigi Vanvitelli”, underwent the Italian version of the NEPSY-2 after cognitive evaluation. Moreover, to assess the pain level and disability grade during daily activity, the VAS and PedMIDAS scales were used. MwoA children were comparable with the control group of 38 children with respect to age, gender, language, and education level. Written informed consent was obtained from all parents and from children directly, when appropriate. MwoA children differed from controls significantly among the NEPSY-2 subscales, with a relevant relationship between the frequency and intensity of the attacks. In conclusion, the results of the present pilot study may suggest that MwoA could impact significantly neuropsychological functioning in children.
Dark Triad: Associations with juvenile delinquency, conduct disorder and trauma

The Dark Triad (DT) consists of three personality traits (machiavellianism, narcissism, and psychopathy). This is considered relevant for understanding the development of undesirable characteristics for society, frequently observed in young people and adults with antisocial and delinquent behaviours. Aversive personality traits have only recently aroused interest in researchers as a cohesive set of factors. The aim of this study was to analyse the associations of the DT (machiavellianism, narcissism, and psychopathy) with juvenile delinquency, conduct disorder (CD), and trauma. For this, a total sample of Portuguese adolescents (n=601; Mage=15.95 years, SD=1.05 years, range=13-18 years) was used, subdivided into a male forensic group, male school group, and female school group. After the elaboration of multiple linear regression models, the results indicated that the psychopathy dimension was the one with the greatest association with juvenile delinquency and CD, while the narcissism dimension was the one with the greatest association with trauma. In future studies, the associations of the DT with juvenile delinquency, CD, and trauma in Portuguese adolescents should continue to be explored in the forensic and school contexts, to further clarify these relationships and contribute to the development and implementation of prevention and intervention programs for Youth with these characteristics.
Defining Microgames in Education Context

The concept of microgaming in education is relatively new and it has evident potential for supporting learning in various learning environments. However, there is little consensus in the education literature on how micro-games are defined. The present article proposes a conceptual definition of mi-crogames by considering related terms and learning approaches in education. Microgames in education context are defined as very small and short games that provide brief engagement and meaningful experience for players, support learning and instruction toward specific objectives, and integrate with existing resources. This article further elaborates the key definition elements to indicate microgame characteristics and provides some examples to demonstrate the kinds of games that fit this definition. The proposed definition acts as a fundamental starting point to study microgames for educational purposes in the future.
Efficiency and Productivity of Public Hospitals in Serbia Using DEA-Malmquist Model and Tobit Regression Model, 2015–2019

Improving productivity within health systems using limited resources is a matter of great concern. The objectives of the paper were to evaluate the productivity, efficiency, and impact of environmental factors on efficiency in Serbian hospitals from 2015–2019. Data envelopment analysis, Malmquist index and Tobit regression were applied to hospital data from this period, and public hospitals in Serbia exhibited a great variation regarding their capacity and performance. Between five and eight hospitals ran efficiently from 2015 to 2019, and the productivity of public hospitals increased whereas technical efficiency decreased in the same period. Tobit regression indicated that the proportion of elderly patients and small hospital size (below 200 beds) had a negative correlation with technical efficiency, while large hospital size (between 400 and 600 beds), the ratio of outpatient episodes to inpatient days, bed turnover rate and the bed occupation rate had a positive correlation with technical efficiency. Serbian public hospitals have considerable space for technical efficiency improvement and public action must be taken to improve resource utilization.
An initial evaluation of research data management online training at the University of New South Wales

In response to low research data management engagement at the University of New South Wales, Australia, an introductory research data management online training was developed and rolled out to all newly enrolled Higher Degree Research candidates. This article outlines the development process of the research data management online training and provides an initial evaluation of the training from the perspectives of the candidates and the university. As such, this article joins up with existing literature on research data management training to assist institutions and research data management stakeholders with the development of research data management training to help researchers and research students enact research data management best practices. Overall, the majority of the candidates (n = 643) were satisfied with the quality of the training and found it helpful. The benefits the training brought to the university are mapped out by linking institutional research data management problems, the research data management online training’s design and findings into a coherent narrative.
Optimum power and efficiency of piezoelectric vibration energy harvesters with sinusoidal and random vibrations

Assuming a sinusoidal vibration as input, an inertial piezoelectric harvester designed for maximum efficiency of the electromechanical energy conversion does not always lead to maximum power generation. In this case, what can be gained by optimizing the efficiency of the device? Detailing an answer to this question is the backbone of this paper. It is shown that, while the maximum efficiency operating condition does not always lead to maximum power generation, it corresponds always to maximum power per square unit deflection of the piezoelectric harvester. This understanding allows better optimization of the generated power when the deflection of the device is limited by hard stops. This is illustrated by experimental measurements on vacuum-packaged MEMS harvesters based on AlN as piezoelectric material. The results obtained for a sinusoidal vibration are extended to random vibrations. In this case, we demonstrate that the optimum generated power is directly proportional to the efficiency of the harvester, thus answering the initial question. For both types of studied vibrations, simple closed-form formulas describing the generated power and efficiency in optimum operating conditions are elaborated. These formulas are based on parameters that are easily measured or modeled. Therefore, they are useful performance metrics for existing piezoelectric harvesters.
Panax notoginseng saponins attenuate intervertebral disc degeneration by reducing the end plate porosity in lumbar spinal instability mice

Although painkillers could alleviate some of the symptoms, there are no drugs that really cope with the intervertebral disc degeneration (IDD) at present, so it is urgent to find a cure that could prevent or reverse the progression of IDD. During the development of IDD, the cartilaginous end plates (EPs) become hypertrophic and porous by the increase of osteoclast activities, which hinder the penetration of nutrition. The compositional and structural degeneration of the EP may cause both nutritional as well as mechanical impairment to the nucleus pulposus (NP) so that developing drugs that target the degenerating EP may be another option in addition to targeting the NP. In the lumbar spine instability mouse model, we found increased porosity in the cartilaginous EP, accompanied by the decrease in total intervertebral disc volume. Panax notoginseng saponins (PNS), a traditional Chinese patent drug with anti‐osteoclastogenesis effect, could alleviate IDD by inhibiting aberrant osteoclast activation in the porous EP. Further in vitro experiment validated that PNS inhibit the receptor activator of nuclear factor kappa‐Β ligand–induced osteoclast differentiation, while the transcriptional activation of PAX6 may be involved in the mechanism, which had been defined as an inhibitory transcription factor in osteoclastogenesis. These findings may provide a novel therapeutic strategy for IDD.

Efficient Reboot-Based Recovery of In-Memory Databases

SUMMARY Reboot-based recovery is a simple but powerful method to recover applications from failures and unstable states. Reboot-based recovery faces a challenge to apply it to a new type of applications, in-memory databases (DBs) . Unlike legacy applications, since rebooting in-memory DBs loses memory objects including key-value pairs and DB blocks, it is required to restore them, causing severe performance degradation after the reboot. This paper presents an approach that allows us to perform reboot-based recovery of in-memory DBs with lower performance degradation. Our key insight is to decouple data content objects from all the memory objects. Our approach treats data items as data content objects, preserves data content objects on memory across reboots, and enforces restarted in-memory DBs to attach them. To show the e ﬀ ectiveness of our approach, we elaborate the idea into two real-world DBs, MyRocks and memcached. The prototypes successfully mitigate performance degradation after their reboot-based recovery. key words: reboot-based recovery, software rejuvenation, in-memory DBs
Two-Dimensional Subsonic Evaluation of a 15-Percent Thick Circulation Control Airfoil with Slots at Leading and Trailing Edges,

Abstract : A 15-percent-thick circulation control elliptical airfoil section with slots at both leading and trailing edges for tangential blowing was evaluated in a subsonic wind tunnel to determine its potential for high-speed (300-400 knot) helicopter rotor systems. Fore-and-aft slot utilization were determined by local flow direction over the blade as it revolved around the azimuth. Aerodynamic performance was not affected by the addition of an unblown leading edge slot except beyond the usable positive angle of attack range where some loss in lift and increase in drag were noted. At equal plenum pressures, simultaneous blowing from the leading and trailing edges resulted in a decrease in lift, an increase in drag, and a more positive pitching moment than for trailing edge blowing alone.

Delineating the Molecular Events Underlying Development of Prostate Cancer Variants with Neuroendocrine/Small Cell Carcinoma Characteristics

The treatment landscape of prostate cancer has changed dramatically following the advent of novel systemic therapies, most of which target the androgen receptor (AR). Agents such as abiraterone, enzalutamide, apalutamide, darolutamide were designed to further suppress androgen receptor signaling following gonadal suppression achieved by first-line androgen deprivation therapies. These potent AR targeting agents are increasingly used in the earlier stages of the disease spectrum with the goal of delaying disease progression and extending survival. Although these therapies are effective in controlling prostate tumors dependent on or addicted to AR signaling, prostate tumors surviving the onslaught of potent treatments may evolve and develop drug resistance. A substantial proportion of treatment failures can be explained by the development of treatment-induced aggressive prostate cancer variants such as neuroendocrine/small cell carcinoma. These emerging disease entities demand detailed characterization and precise definitions. We postulate that these treatment-induced prostate cancer entities should be defined molecularly to overcome the drawbacks associated with the current clinical and pathological definitions. A precise molecular definition conforms with current knowledge on the molecular evolution of this disease entity and will enable early detection and early intervention.
Mechano-Triboelectric Analysis of Surface Charge Generation on Replica-Molded Elastomeric Nanodomes

Replica molding-based triboelectrification has emerged as a new and facile technique to generate nanopatterned tribocharge on elastomer surfaces. The “mechano-triboelectric charging model” has been developed to explain the mechanism of the charge formation and patterning process. However, this model has not been validated to cover the full variety of nanotexture shapes. Moreover, the experimental estimation of the tribocharge’s surface density is still challenging due to the thick and insulating nature of the elastomeric substrate. In this work, we perform experiments in combination with numerical analysis to complete the mechano-triboelectrification charging model. By utilizing Kelvin probe force microscopy (KPFM) and finite element analysis, we reveal that the mechano-triboelectric charging model works for replica molding of both recessed and protruding nanotextures. In addition, by combining KPFM with numerical electrostatic modeling, we improve the accuracy of the surface charge density estimation and cross-calibrate the result against that of electrostatic force microscopy. Overall, the regions which underwent strong interfacial friction during the replica molding exhibited high surface potential and charge density, while those suffering from weak interfacial friction exhibited low values on both. These multi-physical approaches provide useful and important tools for comprehensive analysis of triboelectrification and generation of nanopatterned tribocharge. The results will widen our fundamental understanding of nanoscale triboelectricity and advance the nanopatterned charge generation process for future applications.
Target Reliability Levels in Present Standards

Abstract The target reliability levels recommended in national and international documents vary within a broad range, while the reference to relevant costs and failure consequences is mentioned only very vaguely. In some documents the target reliability index is indicated for one or two reference periods (1 year, 50 years or life-time) without providing appropriate links to the design working life. This contribution attempts to clarify the relationship between the target reliability levels, costs of safety measures, failure consequences, reference periods and the design working life
Dynamic Changes in Central and Peripheral Neuro-Injury vs. Neuroprotective Serum Markers in COVID-19 Are Modulated by Different Types of Anti-Viral Treatments but Do Not Affect the Incidence of Late and Early Strokes

The balance between neurodegeneration, neuroinflammation, neuroprotection, and COVID-19-directed therapy may underly the heterogeneity of SARS-CoV-2′s neurological outcomes. A total of 105 patients hospitalized with a diagnosis of COVID-19 had serum collected over a 6 month period to assess neuroinflammatory (MIF, CCL23, MCP-1), neuro-injury (NFL, NCAM-1), neurodegenerative (KLK6, τ, phospho τ, amyloids, TDP43, YKL40), and neuroprotective (clusterin, fetuin, TREM-2) proteins. These were compared to markers of nonspecific inflammatory responses (IL-6, D-dimer, CRP) and of the overall viral burden (spike protein). Data regarding treatment (steroids, convalescent plasma, remdasavir), pre-existing conditions, and incidences of strokes were collected. Amyloid β42, TDP43, NF-L, and KLK6 serum levels declined 2–3 days post-admission, yet recovered to admission baseline levels by 7 days. YKL-40 and NCAM-1 levels remained elevated over time, with clusters of differential responses identified among TREM-2, TDP43, and YKL40. Fetuin was elevated after the onset of COVID-19 while TREM-2 initially declined before significantly increasing over time. MIF serum level was increased 3–7 days after admission. Ferritin correlated with TDP-43 and KLK6. No treatment with remdesivir coincided with elevations in Amyloid-β40. A lack of convalescent plasma resulted in increased NCAM-1 and total tau, and steroidal treatments did not significantly affect any markers. A total of 11 incidences of stroke were registered up to six months after initial admission for COVID-19. Elevated D-dimer, platelet counts, IL-6, and leukopenia were observed. Variable MIF serum levels differentiated patients with CVA from those who did not have a stroke during the acute phase of COVID-19. This study demonstrated concomitant and opposite changes in neurodegenerative and neuroprotective markers persisting well into recovery.
The Tourism–Poverty Nexus: Does Tourism Spending Influence Poverty Rates? Empirical Evidence from Regional Vietnamese Data

ABSTRACT This paper addresses the question of whether tourism spending will decrease poverty. Real incomes and tourism spending are usually positively correlated, thus complicating the question of causality from tourism spending to poverty. Regional Vietnamese data are applied in a test of whether tourism spending – in a model of poverty – will increase the forecasting performance compared to a model including only incomes. The test results reveal no improvement of the forecasting performance when tourism spending is included. Thus, there is no evidence of a direct link from tourism spending to poverty, but there may be indirect effects via incomes.
