Four-word lexical bundles in Chinese-English consecutive interpreting—A comparative study between professionals and trainees
Authors: Tang Fang , Jiang Shuzhen
Published: October 2022

As comparative studies on lexical bundles between professional interpreters and trainees are pedagogically significant but rare, this experimental study initiates a comparison on the product and process of four-word lexical bundles in Chinese-English consecutive interpreting between these two groups. Frameworks regarding the structure and strategy of lexical bundles are established to analyze the product of lexical bundles produced by these two groups, and data including interpreters’ interpreting products, notes as well as retrospection and interviews are collected to analyze their process of producing lexical bundles. The results show that the types (Type) and frequencies (Token), except diversity (TTR), of lexical bundles with the “noun and/or prepositional phrase fragments” structure and/or the “equivalence” strategy from professionals are significantly higher than those from trainees. Reasons for inter-group similarities and differences in structural and strategical distributions (product) and strategy adoption (process) are also analyzed. Based on the established interpreting-tailored lexical bundle frameworks, this comparative study presents and explains similarities and differences between professionals and trainees and implies suggestions for the training and learning of interpreting.
Threat from peers: The effect of leaders’ voice endorsement on coworkers’ self-improvement motivation
Authors: Liu Pan , Li Daiheng , Zhang Xiaoyan
Published: October 2022

Existing studies mainly explore the antecedents of voice endorsement and its distal outcomes on voicers themselves. However, few have examined the mechanism of leaders’ voice endorsement on the voicers’ coworkers. Drawing on the self-evaluation maintenance theory, this paper uses perceived status threat as the mediator and trait competitiveness as the moderator to construct a conceptual model to explore the effect of leaders’ voice endorsement on coworkers’ self-improvement motivation. Through an empirical study with 279 sets of questionnaires from a manufacturing enterprise in China, the results show that leaders’ voice endorsement has a positive effect on coworkers’ self-improvement motivation through coworkers’ perceived status threat and that coworkers’ trait competitiveness can strengthen the positive relationship between leaders’ voice endorsement and coworkers’ perceived status threat. In addition, coworkers’ trait competitiveness can strengthen the indirect effect of leaders’ voice endorsement on coworkers’ self-improvement motivation via coworkers’ perceived status threat. The theoretical and practical implications of these findings are discussed.

Authors: Wang Quan , Liu Xinyu , Wang Ting , Zhu Zemeng , Yang Li , Guo Shasha , Li Hui , Sun Qiang
Published: October 2022

Objectives

More and more countries have decided to cancel most or even all COVD-19 restrictions. However, it is unclear how ending of restrictions will affect primary care providers' job satisfaction and organizational commitment. Our objectives are to explore the current status and possible change in primary care providers' job satisfaction and organizational commitment after massive restriction policies ended in China.

Methods

This was a mixed-method study that utilized structured questionnaires and semi-structured qualitative individual interviews. The 20-item Minnesota Satisfaction Questionnaire (MSQ) and 25-item organizational commitment survey were adopted to assess job satisfaction and organization commitment. Descriptive statistics and mediation models, as well as inductive thematic analysis, were used to analyze quantitative and qualitative data.

Results

A total of 18 interviews and 435 valid survey responses were included in our analysis. The average scores for job satisfaction and organizational commitment were 80.6 and 90.8. The thematic analysis revealed one major theme: ethical and moral responsibility to provide care as primary care providers, on which we established a mediation model. The mediation analysis revealed that normative commitment could positively affect the other four dimensions of organizational commitment and job satisfaction. The direct effect of affective commitment on job satisfaction was significant (LLCI = 0.11, ULCI = 0.31), and the mediators were identified to have a partial mediating effect instead of a total mediating effect.

Conclusion

After COVID-19 restrictions end, the job satisfaction and organizational commitment of primary care providers will return to levels before the pandemic and during this estimated process, a brief rise in resignation is predictable. The normative commitment positively affects the other four dimensions of organizational commitment and job satisfaction for primary care providers, which suggests a possible way to motivate primary care providers when restrictions end.
Stay-at-home and face mask policy intentions inconsistent with incidence and fatality during the US COVID-19 pandemic
Authors: Wu Samuel X. , Wu Xin
Published: October 2022

During the COVID-19 pandemic, many states imposed stay-at-home (SAH) and mandatory face mask (MFM) orders to supplement the United States CDC recommendations. The purpose of this study was to characterize the relationship between SAH and MFM approaches with the incidence and fatality of COVID-19 during the pandemic period until 23 August 2020 (about 171 days), the period with no vaccines or specific drugs that had passed the phase III clinical trials yet. States with SAH orders showed a potential 50–60% decrease in infection and fatality during the SAH period (about 45 days). After normalization to population density, there was a 44% significant increase in the fatality rate in no-SAH + no-MFM states when compared to SAH + MFM. However, many results in this study were inconsistent with the intent of public health strategies of SAH and MFM. There were similar incidence rates (1.41, 1.81, and 1.36%) and significant differences in fatality rates (3.40, 2.12, and 1.25%; p < 0.05) and mortality rates (51.43, 34.50, and 17.42 per 100,000 residents; p < 0.05) among SAH + MFM, SAH + no-MFM, and no-SAH + no-MFM states, respectively. There were no significant differences in total positive cases, average daily new cases, and average daily fatality when normalized with population density among the three groups. This study suggested potential decreases in infection and fatality with short-term SAH order. However, SAH and MFM orders from some states' policies probably had limited effects in lowering transmission and fatality among the general population. At the policy-making level, if contagious patients would not likely be placed in strict isolation and massive contact tracing would not be effective to implement, we presume that following the CDC's recommendations with close monitoring of healthcare capacity could be appropriate in helping mitigate the COVID-19 disaster while limiting collateral socioeconomic damages.

Published: October 2022

Objective

To evaluate the combined effects of robotic exoskeleton and functional electrical stimulation (FES) training on muscle composition during over-ground gait training in persons with acute spinal cord injury (SCI).

Design

Randomized crossover pilot study.

Setting

Inpatient-rehabilitation Hospital.

Participants

Six individuals with acute SCI.

Intervention

Participants were randomized to either receive training with the Ekso® Bionics exoskeleton combined with FES in addition to standard-of-care or standard-of-care alone.

Outcome measures

The main outcome measures for the study were quantified using magnetic resonance imaging (MRI), specifically, lower extremity muscle volume and intramuscular adipose tissue (IMAT). Static balance and fall risk were assessed using the Berg Balance Scale.

Results

Significant improvements were observed in muscle volume in the exoskeleton intervention group when compared to only standard-of-care (p < 0.001). There was no significant difference between the groups in IMAT even though the intervention group saw a reduction in IMAT that trended towards statistical significance (p = 0.07). Static balance improved in both groups, with greater improvements seen in the intervention group.

Conclusions

Early intervention with robotic exoskeleton may contribute to improved muscle function measured using MRI in individuals with acute SCI.
“Together, We Can Do This”: The Best Sport Teams Are Greater Than the Sum of Their Parts
Authors: Slater Matt , Barker Jamie
Published: October 2022

Once upon a time, it was believed that the sport team with the best individual star players would be most likely to win all the trophies. Then one day, athletes, coaches, and sport fans, together with scientists (including sport psychologists), noticed that this did not always happen—so people began to doubt the idea. This was a concern because, for coaches to create great sport teams that can reach their potentials, the key ingredients for team success must be understood. Over time, there has been a shift from looking at the talent of individual star players to looking at teamwork. In this article, you will discover how the feeling of connection and relationship between players—their sense of togetherness—is the key ingredient in sport-team success. You will also learn some ideas for how to develop togetherness.
Why Are Some Plants Hairy?
Authors: Vasquez Alejandro R. , Kaur Ishveen , Kariyat Rupesh
Published: October 2022

Whether we live in a sprawling metropolis or on a rural farm, plants and insects are part of our daily lives, and many of them cannot exist without the other. Insects help plants reproduce via pollination, and plants provide insects with food and shelter. However, plants also require nutrition to grow, develop, and reproduce; and plant-eating insects can damage them. Over millions of years of living together, plants have evolved multiple defense strategies to defend themselves against insects. One such defense is tiny hair-like projections called trichomes. In this article, we explain how plants use their trichomes as a creative and unique weapon to protect themselves from insect herbivores. Trichomes can cause physical injury, release toxic chemical compounds, and even cause internal injury to insects. We also discuss how plant-eating insects counter these plant defenses using their own defenses—leading to a tug-of-war for survival.
Rapid evaluation of COVID-19 related service and practice changes in health and human services using tailored methods
Authors: Williams Eleanor , Gawaya Milbert , Terrill Desiree
Published: October 2022

The COVID-19 pandemic required substantive delivery and practice changes for government services under tight timeframes and high public scrutiny. These urgently implemented service changes provided the opportunity for evaluators to support decision-makers to understand the impact of adaptations for those delivering and receiving health and human services. Tailored rapid evaluation methods (REM) provide a pragmatic approach to generating timely information for evidence-based policy and decision-making under these conditions. Drawing from features of a range of existing rapid evaluation models, as well as developmental and utilization-focussed evaluation theory, this article outlines the design and implementation of a novel REM approach and considers the benefits of both tailoring and standardizing rapid evaluation approaches to meet end-user needs. The tailored REM approach and mixed methods are contextualized and compared to other documented rapid evaluation models to demonstrate the purpose and value of customization. This article builds on previous descriptions of the implementation of a novel REM approach to provide a comparative account of tailored rapid evaluation methods. The article outlines the drivers that led to the selected tailoring of the REM approach, and shares lessons learned in the context of the COVID-19 pandemic by a large internal government evaluation unit (Department of Health and Human Services) in Victoria, Australia. The customized features of REM ensure that it can consider the experiences of those delivering and receiving services, and inform near-term decision-making on programme and policy design in emergency and fast-paced contexts. The article shares a case study of a rapid evaluation of telehealth in pediatric care to demonstrate insights from tailoring the REM approach in practice. The REM method was utilized with the aim of delivering findings in a time-sensitive manner to rapidly inform decision making for policy-makers. Key enablers for the tailored REM protocol include the use of multi-disciplinary teams, flexible evaluation design, and a participatory approach that facilitates stakeholder involvement throughout delivery. Insights from the case study and methods presented seek to inform practice for evaluators who intend to or may want to tailor their own rapid evaluation model in resource and time-limited settings.
Examining karate and football perceptions and their links with athlete engagement and quality of life
Authors: Limpo Teresa , Rödel Gabriela , Tadrist Sid
Published: October 2022

The importance of perceptions as determinants of people's behavior has been well-established, but little is known about athletes' perceptions of their sport and the links of these perceptions with other correlates. In this study, we compared karate (n = 51) and football (n = 49) athletes' perceived benefits and aggressiveness risks from their sports and examined whether these perceptions predicted athletes' engagement and quality of life (QoL). Participants completed perception measures of karate and football, and engagement and QoL measures. Results showed that karateka perceived more benefits and fewer risks in karate than football, but footballers generally perceived equal benefits and risks in both sports. Both athlete groups perceived similar physical and psychological benefits in their own sport, but deemed physical benefits as prominent outcomes in the other sport. Notably, karateka's perceived benefits about karate predicted engagement directly and QoL indirectly via vigor. Overall, karate athletes' perceptions seemed to be relevant to experiencing fulfillment in training and general well-being.
OLIF versus MI-TLIF for patients with degenerative lumbar disease: Is one procedure superior to the other? A systematic review and meta-analysis
Authors: Wang Jianqiang , Liu Jingwei , Hai Yong , Zhang Yiqi , Zhou Lijin
Published: October 2022

Purpose

To compare the effectiveness and safety of oblique lateral interbody fusion (OLIF) and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for degenerative lumbar disease.

Methods

We searched relevant studies in Embase, PubMed, Cochrane, and Web of Science databases comprehensively from inception to March 2022. The data were extracted from included studies, including operation indications, radiographic parameters, and clinical outcomes. Random or fixed-effects models were used in all meta-analyses according to the between-study heterogeneity.

Results

In total, 30 studies, including 2,125 patients, were included in this meta-analysis. Our study found similar disk height, length of hospital stay, visual analog scale (VAS), and Oswestry disability index(ODI) between the two groups. However, the OLIF showed an advantage in restoring lumbar lordotic angle compared with MI-TLIF, with the pooled mean change of 17.73° and 2.61°, respectively. Additionally, the operative time and blood loss in the OLIF group appeared to be less compared with the MI-TLIF group. Regarding complications, the rates of the two groups were similar (OLIF 14.0% vs. MI-TLIF 10.0%), but the major complications that occurred in these two procedures differed significantly.

Conclusion

The results of disk height, length of hospital stay, VAS, and ODI between the OLIF and MI-TLIF groups were similar. And the OLIF was superior in restoring lumbar lordotic angle, operative time, and blood loss. However, the OLIF group's complication rate was higher, although not significantly, than that in the MI-TLIF group.
Environmental factors associated with the prevalence of ESBL/AmpC-producing Escherichia coli in wild boar (Sus scrofa)
Authors: Günther Taras , Kramer-Schadt Stephanie , Fuhrmann Marcel , Belik Vitaly
Published: October 2022

Antimicrobial resistances (AMR) in bacteria, such as ESBL/AmpC-producing E. coli, are a burden to human and animal health. This burden is mainly driven by the consumption and release of antimicrobial substances into the environment. The pollution and contamination of habitats by AMR in bacteria and antimicrobial substances can lead to the transmission of bacterial AMR to wildlife. Therefore, it is necessary to understand the transmission cycle of antibiotics and resistant bacteria between humans, and animals as well as their occurrences in the environment. Environmental factors associated with the occurrence of bacterial AMR in wildlife can lead to a better understanding of the distribution of bacterial AMR in humans and animals using One Health approaches. Here, we analyzed data gathered in the framework of the German zoonoses monitoring program in 2016 and 2020 using spatiotemporal statistics to identify relevant environmental factors (e.g., livestock density, climatic variables, and human density) in association with the spatial distribution of ESBL/AmpC-producing E. coli. For this purpose, we developed a generic data integration and analysis pipeline to link spatially explicit environmental factors to the monitoring data. Finally, we built a binomial generalized linear mixed model (GLMM) to determine the factors associated with the spatial distribution of ESBL/AmpC-producing E. coli. In 2016 and 2020, 807 fecal samples from hunted wild boar (Sus scrofa L.) were randomly taken in 13 federal states and selectively analyzed for ESBL/AmpC-producing E. coli. Forty-eight isolates were identified in 12 German federal states, with an overall prevalence of 6%. We observed an almost three times higher probability of ESBL/AmpC-producing E. coli isolates in wild boar in counties with high cattle densities (OR = 2.57, p ≤ 0.01). Furthermore, we identified a seasonal effect in areas with high precipitation during the off-hunting seasons (OR = 2.78, p = 0.025) and low precipitation throughout the years (OR = 0.42, p = 0.025). However, due to the low amount of identified isolates, confidence intervals were wide, indicating a high level of uncertainty. This suggests that further studies on smaller scales need to be conducted with multiannual data and improved metadata, e.g., on the location, the hunting procedure, and species characteristics to be collected during field sampling.
Mechanical and Wear Properties of Al/TiC Composites Fabricated via Combined Compo-Casting and APB Process
Authors: Wang Weining , Heydari Vini Mohammad , Daneshmand Saeed
Published: October 2022

One of the popular techniques to fabricate metal matrix composites is the compo-casting process. The un-uniform spreading of reinforced subdivisions (particles) inside the metallic matrix and the lack of desirable mechanical properties of the final produced composites due to the low bonding strength among the metal matrix and reinforcement particles are the main challenges in this process. The warm accumulative press bonding (APB) technique was utilized as the supplementary technique to improve the mechanical and microstructural evolution of casted Al/TiC composite bars to remove these difficulties. So, using the tensile test, average Vickers micro hardness test, wear test and scanning electron microscopy (SEM), the microstructure evolution and mechanical properties of these composites have been considered vs. various WAPB steps. The SEM morphology of samples revealed that big titanium carbide clusters are broken and make a uniform distribution of titanium carbide particles at higher APB steps. It was shown that the cumulative forming steps of the APB process improved the mechanical properties of composites. In general, combining the compo-casting and APB process would result in making Al/TiC composites with high uniformity and good mechanical and microstructural properties.

Published: October 2022

Named entity recognition is a basic task in natural language processing, and there is a large number of nested structures in named entities. Nested named entities become the basis for solving many tasks in NLP. A nested named entity recognition model based on dual-flow features complementary is proposed for obtaining efficient feature information after text coding. Firstly, sentences are embedded at both the word level and the character level of the words, then sentence context information is obtained separately via the neural network Bi-LSTM; Afterward, two vectors perform low-level feature complementary to reinforce low-level semantic information; Sentence-local information is captured with the multi-head attention mechanism, then the feature vector is sent to the high-level feature complementary module to obtain deep semantic information; Finally, the entity word recognition module and the fine-grained division module are entered to obtain the internal entity. The experimental results show that the model has a great improvement in feature extraction compared to the classical model.

Published: October 2022

The physicochemical characterization and kinetic evaluation of the thermal and co-pyrolysis of groundnut de-oiled cake (GDC) and PET plastic is examined in this present study. A bomb calorimeter, proximate/CHNS analysis, and a thermogravimetric analyzer were used to study the physicochemical characteristics of the biomass and plastic. By using a FTIR analysis, it was found that both samples had distinct functional groups. Iso-conversional models, such as Friedman’s, the Kissinger–Akhaira–Sunose, the Ozawa–Flynn–Wall, Starink’s, and the distributed activation energy models were employed in the calculation of the kinetic parameters. The physicochemical characterization provided valuable insights into the pyrolysis characteristics. The rate at which the feedstock was heated were 10, 20, and 30 °C min−1, and were used to study the thermal breakdown behavior of the GDC and PET by the TGA. The following temperatures are the active pyrolysis zones for the thermal pyrolysis and the co-pyrolysis: for the groundnut de-oiled cake, T = 150–650 °C; for the PET, T = 375–600 °C; and for the co-pyrolysis, T = 175–550 °C. For the thermal pyrolysis (for GDC, E = 127.49 kJ mol−1; PET, E = 201.45 kJ mol−1); and the co-pyrolysis (E = 175.86 kJ mol−1), Kissinger–Akhaira–Sunose revealed low activation energy.
The Software Cache Optimization-Based Method for Decreasing Energy Consumption of Computational Clusters
Authors: Kravets Alla G. , Egunov Vitaly
Published: October 2022

Reducing the consumption of electricity by computing devices is currently an urgent task. Moreover, if earlier this problem belonged to the competence of hardware developers and the design of more cost-effective equipment, then more recently there has been an increased interest in this issue on the part of software developers. The issues of these studies are extensive. From energy efficiency issues of various programming languages to the development of energy-saving software for smartphones and other gadgets. However, to the best of our knowledge, no study has reported an analysis of the impact of cache optimizations on computing devices’ power consumption. Hence, this paper aims to provide an analysis of such impact on the software energy efficiency using the original software design procedure and computational experiments. The proposed Software Cache Optimization (SCO)-based Methodology was applied to one of the key linear algebra transformations. Experiments were carried out to determine software energy efficiency. RAPL (Running Average Power Limit) was used—an interface developed by Intel, which provides built-in counters of Central Processing Unit (CPU) energy consumption. Measurements have shown that optimized software versions reduce power consumption up to 4 times in relation to the basic transformation scheme. Experimental results confirm the effectiveness of the SCO-based Methodology used to reduce energy consumption and the applicability of this technique for software optimization.
Techno-Economic Model for Scaling Up of Hydrogen Refueling Stations
Authors: Caponi Roberta , Bocci Enrico , Del Zotto Luca
Published: October 2022

In a recent publication, the Hydrogen Council states that scaling up to greater production volumes leads to significant cost savings as a consequence of the industrialization of equipment manufacturing, increased utilization, standardization, and improvements in system efficiency and flexibility. In this study, a component-oriented techno-economic model is applied to five different European hydrogen refueling stations within the 3Emotion project, which is planned to ensure capacities sufficient for increasing a fleet to 100 fuel cell buses. The investigation of the various cases shows that the levelized cost of hydrogen (LCOH) for large-scale applications will be in the range of about 4 €/kg to 7 €/kg within the boundaries analyzed. On-site production facilities were found to be the lower-cost design, benefiting from the high volumes at stake and the economy of scale with respect to decentralized production due to the significant costs associated with retail hydrogen and transport. This study also illustrates the effects on the LCOH of varying the hydrogen delivery and production prices using a sensitivity analysis. The results show that, by utilizing high-capacity trailers, the costs associated with delivery could be reduced by 30%. Furthermore, green hydrogen production could be a competitive solution if coupled with low electricity prices, resulting in an LCOH between 4.21 €/kg and 6.80 €/kg.

Published: October 2022

For decision-making and governance, smart cities depend on tracking data collected via a substantial percentage of wireless sensing nodes. However, several limitations affect Wireless Sensor Network (WSN)-based Internet of Things (IoT) services, such as low battery life, recurrent connectivity problems due to multi-hop connections, and a limited channel capacity. Furthermore, in many systems, clustering and routing are handled independently, which prevents the adaptation of effective strategies for optimal energy usage and prolonged network lifespan. This research gathers data from heterogeneous IoT nodes linked via WSN and distributed across a smart infrastructure. There are two interrelated problems to be addressed with respect to energy efficiency computations: clustering and routing. We provide a new clustering strategy through which efficient routing of critical and regular data is handled. As a result, both clustering and routing have been significantly strengthened, which balances the communication load across different sectors of the smart infrastructure network. Minkowski distance and ranking strategy are used for routing and selecting cluster heads, respectively. Deterministic distributed–time division multiple access (DD-TDMA) scheduling is employed to balance the communication load across the network. The experimental results show that the proposed work outperforms some of the popular cluster-based routing strategies.

Authors: Islam Ziaul , Khan Faisal , Ullah Basharat , Milyani Ahmad H. , Ahmed Azhari Abdullah
Published: October 2022

Axial flux permanent magnet (AFPM) machines are good candidates for electric vehicle applications due to their high torque density, improved efficiency, and better flux distribution; thus, they are often used. A dual-rotor single-stator AFPM machine with four differently shaped permanent magnet (PM) rotors is investigated. The main aim of this paper is to enhance the average torque while minimizing the cogging torque and torque ripples at the expense of low PM volume. The proposed machines are analyzed in terms of flux linkage, back-EMF, cogging torque, average torque, and torque ripples. The analysis reveals that the machine with an arc-shaped PM rotor performs better than the others. In addition, the trapozoidal arc-shaped PM used in the AFPM machine outperforms the hexagonal, skew arc, and traditional trapezoidal PMs. The torque density of the trapezoidal-shaped PM machine is 40.23 (KNm/m3), while that of the hexagonal shape is 32.46 (KNm/m3), that of the skew arc shape is 39.78 (KNm/m3), and that of the arc shape is 50.38 (KNm/m3).
A Simulation Experiment on Quality Dynamics of Reclaimed Water under Different Flow Exchanges
Authors: Pan Chengzhong , Guo Zhongfang , Luo Mingjie
Published: October 2022

Reclaimed water plays an important role in maintaining urban aquatic ecosystems, especially in areas with water shortages. However, there is little information on water quality dynamics and its driving mechanism in reclaimed water bodies. The simulated experiments were conducted to investigate the effect of flow exchange on water quality dynamics and soil microbial diversity for 100% reclaimed water and mixed water (50% reclaimed and 50% stream water), and the exchange periods ranged from 2 to 40 days. The results showed that the degradation coefficients (K) of CODMn and NH3–N were 0.015 d−1 and 0.001 d−1 for the mixed water, while their K values were negative for the reclaimed water. The flow exchange had little effect on water quality dynamics for the mixed water, which may be attributed to the relatively low concentration of TP in this reclaimed water. A small or great exchange period led to a relatively high fluctuation in K during the experimental period and corresponded to a worse soil microbial diversity. These results indicate that it is not recommended to fill an isolated urban lake with 100% reclaimed water and that a suitable flow exchange period of 5~10 days could help self-purify the water quality.
Biomechanical Asymmetry of Strength and Dynamic Balance Kinetics in Middle-Ages with Adhesive Capsulitis of the Hip
Authors: Choi Moonyoung , Kim Yonghwan
Published: October 2022

The representative clinical features of adhesive capsulitis of the hip (ACH) are restricted range of motion (ROM) and pain. However, reports on kinetics such as strength and dynamic balance that explain physical functions are rare. This study compared subjective hip scores using Copenhagen Hip and Groin Outcome Score (HAGOS) and ROM using a manual goniometer as well as strength using isokinetic equipment, and dynamic balance through the Y-balance test, between patients with ACH and healthy individuals. Data of 193 middle-aged participants (men: 99 and women: 94) were analyzed. The ACH group scored significantly lower in all six HAGOS sub-sections. Hip joint flexion, abduction, internal and external rotation ROM were significantly lower in ACH compared to healthy group. These results were the same for men and women. In the strength of men and women, flexion, adduction, and abduction, and dynamic balance in all three directions were significantly decreased in ACH. Meanwhile, there were no significant between-group differences in the functional decrease in extension and adduction of ROM, and extension strength. In conclusion, subjective evaluation and dynamic balance of patients with ACH were decreased in the all parts. In ROM, flexion, abduction, internal rotation, and external rotation were restricted except for extension and adduction. Men and women with ACH maintained extensor strength, but had weakened strength in flexion, adduction and abduction. This information will be useful for therapists to understand the biomechanical properties of ACH and to design effective rehabilitation programs.

This study analyzed changes in the psychological health of students who were in the final year of their nursing degree during the COVID-19 pandemic and later served as nursing professionals in hospitals. Methods: A prospective longitudinal study was conducted over two periods of time (the first in April 2020 and the second 6 months later, in December 2020) with 296 students for a T0 baseline (rate response 68.83%) and 92 students for a T1 post-test sample (response rate 31.08%). The data were electronically collected using the Hospital Anxiety and Depression Scale, the Life Satisfaction Questionnaire, the Resilience Scale, and a post-traumatic stress questionnaire. The mean age of the sample participants was 24.17 years (SD = 5.51), and 89.11% were female. During the pandemic, 14.11% of students showed scores that indicated depression, and 32.61% showed scores that indicated anxiety. In December 2020, 86.5% of the participants were working as nurses, and the percentages of those with anxiety (12%) and depression (4.3%) were significantly lower than in the first sample period. A total of 20.7% of the participants had post-traumatic stress. High scores for resilience were significantly associated with better quality of life and lower levels of anxiety, depression, and post-traumatic stress. Conclusions: Although the percentages of participants with anxiety and depression decreased, they still presented with mental health problems.

(1) Background: Obesity is one of the most prevalent health problems worldwide. Studies have evidenced that the increase in body weight affects the normal neuromusculoskeletal function, which leads to abnormal gait patterns and impaired balance. (2) Objective: The aim of this study was to examine the influence of dual-task activity (cognitive-motor task) on gait parameters and balance among obese students. (3) Material and methods: A cross-sectional study was conducted among students (18–28 years old), including 120 obese and 120 age-matched normal-weight control subjects, selected at random using simple random sampling, from the Majmaah, Riyadh, Dammam, and Jizan regions of Saudi Arabia. The gait speed was measured in seconds while the controls and the obese subjects performed a dual-task activity of walking down a level, well-lit, narrow lane at their own speed, counting backwards from 100 by 4 s. (4) Results: The results of our study suggest a significant difference in the effect of the dual-task paradigm on the gait speed (t = 21.05, p = 000) of obese participants when compared to their age-matched counterparts. A significant correlation was found between BMI and gait speed and balance, irrespective of the gender of the obese student. A high degree of positive correlation (r = 0.705, p < 0.001) was found between BMI and gait speed, and a high degree of inverse correlation (r = −0.648, p < 0.001) was found between BMI and balance among obese students A multiple regression model explained 60% of the variance in gait speed and was statistically significant (R2 = 0.60, F (4, 235) = 90.65, p = 0.000) with BMI (β = 0.018, p = 0.000) and balance (β = 0.015, p = 0.000) significantly predicting gait speed. (5) Conclusion: The results of the current study provide evidence that obesity significantly influences gait speed and balance due to the inclusion of a contemporaneous cognitive task. The results also suggest that the dual-task paradigm affects both genders equally.

Addressing the mental health needs of healthcare workers (HCWs), who are at high risk of suicide, is an important public health issue. Therefore, this systematic review investigated the effect of psychosocial intervention targeting suicidal behavior (i.e., suicidal ideation, attempt, or fulfillment) of HCWs. Five electronic databases were searched for interventional studies reporting HCWs’ suicidal behavior outcomes. Only two interventional studies were included in this review, and no consistent conclusion was drawn from the existing literature regarding the psychosocial prevention strategies focusing on the suicide risk of HCWs. The results indicate that compared with numerous observational studies reporting poor mental health and/or severity of suicidal risk among HCWs, intervention studies using psychosocial strategies to reduce the risk of suicide are relatively scarce. Although the insufficient number and heterogeneity of the included studies leave the results inconclusive, our findings emphasize the need to fill the research gap in this field. The causes of the gap are further explored, and suggestions for future research are provided.

Alopecia Areata (AA) is a chronic condition which has been associated with poor quality of life and mood status disturbances. The aim of this study is to compare the sleep quality between AA patients and controls, and to analyze the impact of poor sleep quality on patients with AA regarding mood status disturbances, quality of life and sexuality. A cross-sectional study including patients suffering from mild-to-severe AA and sex- and age-matched healthy controls was performed. Socio-demographic and clinical variables, sleep quality, quality of life, sexual disfunction, anxiety, depression and personality were collected using validated questionnaires. A total of 120 participants (60 patients and 60 controls) were included. Patients with AA showed worse sleep scores than controls (p = 0.003), as well as higher rates of anxiety and depression (p < 0.05). After a multivariate analysis, a worse sleep quality was found to be linked to anxiety, depression, a poorer quality of life and a type D personality score independently of the disease severity. In light of the results, patients with AA have a worse sleep quality than healthy controls. A poor sleep quality is associated with anxiety, depression and a worse quality of life, therefore being a general marker of a poor quality of life. Screening for sleep disturbances in specialized units could be useful to detect patients who could benefit from additional psychological support.
The Impact of Job Stress, Role Ambiguity and Work–Life Imbalance on Turnover Intention during COVID-19: A Case Study of Frontline Health Workers in Saudi Arabia
Authors: Alblihed Mohammed , Alzghaibi Haitham Ali

The main objective of the present study is to examine the impact of job stress, role ambiguity, work–life imbalance and burnout on employee turnover intention. Moreover, the mediating role of burnout between job stress, role ambiguity, work–life imbalance and turnover intention is also examined. The data collection for this quantitative research was conducted through the “Questionnaire” technique. The questionnaire was developed based on previously established questions available in the literature. The data were collected using simple random sampling from the healthcare workers of KSA. From the distributed questionnaire, 73.5% of the usable questionnaires were returned. This study used SPSS and PLS for the analysis of the data to highlight the most significant variables that impact the employees’ turnover intentions among KSA health workers. The findings show that job burnout is clearly related to turnover intentions and is positively affected by both role stress and role ambiguity. Moreover, a statistically positive association is found between work–life imbalance and burnout among the healthcare workers in KSA. Furthermore, the mediating role of burnout is also confirmed in this study. The study also indicates that role ambiguity and role stress due to COVID-19 may create burnout among employees, which may lead to turnover intention among healthcare workers. There is a lack of research on the assessment of the impact of the novel COVID-19-related job stress, role ambiguity and work–life imbalance on the medical staff’s turnover intentions in hospitals. This study fills the gap of the limited studies conducted regarding the identification of the factors that can create turnover intention among healthcare workers of KSA by providing empirical evidence from a Gulf country, Saudi Arabia. This study provides managerial implications for hospital management and health policymakers to develop a strategy to retain the employees. Furthermore, healthcare administrators need to pay close attention to front line workers’ turnover intentions as these medical heroes are the vital part of our society who assist patients to receive their initial treatment during the COVID-19 pandemic.

Background: Intensive care unit (ICU) and homecare unit professionals are susceptible to higher levels of stress and burnout than other healthcare professionals, which has an impact on their well-being, and in turn on their patients. In terms of data, there is not much research about the effects of psychological interventions on ICU and homecare professionals. The aim of this study was to investigate the effectiveness of Wellbeing Training based on Contemplative Practices (WTCP) for the increase of psychological functioning in a sample of ICU and homecare professionals. Methods: A pilot and feasibility non-randomized clinical trial was conducted. Participants in the WTCP group (n = 19) attended an at-work 8-session/2 h group WTCP program aimed at directly training four basic skills: (a) sustained positive emotions, (b) recovery from negative emotions, (c) pro-social behavior and generosity, and (d) mind wandering, mindfulness, and “affective stickiness”. Nineteen professionals were allocated in the control group. Results: Results indicated that WTCP had a positive impact on self-compassion, personal accomplishment (burnout), and frequency of negative emotions. Moreover, a thematic analysis of participant interviews (n = 14) was conducted. Conclusions: These preliminary results are promising, though future research is needed to evaluate the effectiveness of WTCP using randomized controlled trial methodologies.
Privatization and Multi-Fatality Disasters: A Causal Connection Exposing Both Worker and Citizen Health and Safety Failures in the UK?
Authors: Beck Matthias , Watterson Andrew
Published: October 2022

Although several countries have experienced large-scale privatization initiatives, relatively little is known about the impact of these initiatives on the health and safety of workers and resident populations. Examining data on technical (as compared to natural) multi-fatality disasters collected in the WHO’s Emergency Events Database (EM-DAT) for the UK and a number of European comparator countries for recent decades, this paper shows that the incidence of these disasters and the number of deaths resulting from them rose significantly in the UK during the period from 1979 to 1991 when the country engaged in extensive and aggressive privatization campaigns which were supported by several consecutive Conservative governments. This observed UK blip or abnormal increase in multi-fatality disasters is apparent for the UK both in terms of a “within-country” comparison (i.e., when we compare the privatization period of 1979 to 1997 with other periods), as well as when viewed in terms of comparisons with the comparable European countries of Germany, France, and Italy for the same period (1979 to 1997). Contrary to previous analyses which suggested that there is no clear link between privatization and deterioration of health and safety, this paper concludes that the UK privatization experience (1979–1997) provides robust country-specific evidence of privatization initiatives leading to increases in the number of multi-fatality technological disasters as well as related fatalities. This evidence should be seen as a deterrent to similarly extensive and aggressive initiatives which, particularly in less developed countries, could result in similarly disastrous outcomes.
Burnout, Social Comparison Orientation and the Responses to Social Comparison among Teachers in The Netherlands
Authors: Buunk Abraham Pieter , Brenninkmeijer Veerle
Published: October 2022

(1) Background: Teaching is a profession in which burnout constitutes a prevalent issue and provides ample opportunity to compare oneself with one’s colleagues, i.e., social comparison. The purpose of this research in the Netherlands was to examine responses to social comparison, in relation to burnout, and to individual differences in social comparison orientation (SCO). (2) Methods: Study 1 employed a retrospective measure to assess responses to social comparison. In Study 2, teachers were confronted with a scenario describing either a well or a poorly functioning colleague. (3) Results: Burnout was associated with more negative responses to well and to poorly functioning colleagues, with a less positive response to well-functioning colleagues. This last effect was fully due to the degree to which one identified or contrasted oneself with this colleague. Especially among high-SCO individuals, identification with a well-functioning colleague was accompanied by a positive affect. High-burnout individuals reported more identification with poorly functioning colleagues, and more contrast and less identification with well-functioning colleagues. Responses to well-functioning colleagues were more strongly related to burnout among those high in SCO. (4) Conclusions: An especially negative affect after comparison with well-functioning colleagues is typical for individuals high in burnout, particularly among individuals with a dispositional tendency to compare themselves with others.
