Infectious alleles of endogenous banana streak viruses (eBSVs) are present in the genome of all banana interspecific cultivars, including plantains and cooking types. Activation of these infectious eBSV alleles by biotic and abiotic stresses leads to spontaneous infections by cognate viruses and raises concerns about their ability to promote outbreaks of banana streak viruses under field cultivation conditions. We undertook a comprehensive risk assessment study of infectious eBSV alleles of species BSOLV, BSGFV and BSIMV in banana interspecific cultivars in Guadeloupe, a tropical island of the Caribbean where bananas are grown for export and local markets. We carried out a prevalence survey of BSOLV, BSGFV and BSIMV species in a range of cultivars grown in Guadeloupe. Our results suggest that BSOLV and BSGFV infections arise from the activation of infectious eBSVs rather than vector-borne transmission and point to a correlation between altitude and infection rates in interspecific hybrids with AAB genotypes. We studied the dynamics of activation of infectious eBSOLV and eBSGFV alleles by tissue culture and field cultivation in a range of cultivars. We showed that tissue culture and field cultivation trigger distinct activation pathways, resulting in distinct activation patterns. We also showed that activation decreased over time during cell culture and field cultivation and that BSV infections arising from the activation of infectious eBSV alleles cause symptomless infections in the most cultivated plantain in Guadeloupe, French Clair. Overall, our study shows that the risk of BSV outbreaks resulting from the activation of infectious eBSVs in plantain originating from vegetative multiplication is negligible in Guadeloupe.
How Does the Horizontal Position of Pictures and Text Affect Product Evaluation? Based on Left and Right Position Effect
Authors: Huang Zan , Du Yingjue , Xu Feifei , Hu Chuming
Published: July 2022

Due to the untouchability of online shopping environment, image and text description, as two main ways of product information display, are important indicators for consumers to evaluate products. However, few studies have discussed the synergistic effects of image and text information on consumers. In the present study, in conjunction with the left-right position effect, we examine the expectation that horizontal placement of visual stimuli in different directions has a strong influence on consumers’ product evaluation preferences. This implicit assumption is based on consumers’ unconscious psychological need for closure when processing information. The authors conducted three studies to investigate the relative effects of image information and text statements at different locations in online shopping pages on consumer product evaluations. The results show that: (1) when the evaluation object is a search product, compared with the display mode of left text-right image, the display mode of left image-right text plays a more significant role in consumer product evaluation. The results of experiential products were just the opposite. The way of presenting the text declaration on the left and image on the right has a stronger impact on consumers’ evaluation preference for experiential products (Study 1 and Study 3). (2) The difference in consumers’ evaluation mode of different presentation sequences based on product attributes is driven by their visual information processing fluency (Study 2). These preferences are robust, and it is worth noting that only the order of graphic presentation has no significant influence on consumer product evaluation preference.
Enhancing Career Interest Assessment in South Africa: Lessons Learned From the Development of the South African Career Interest Inventory-IsiXhosa Version
Authors: Jansen van Vuuren Nicola , Rabie Stephan , Naidoo Anthony Vernon
Published: July 2022

Career interest assessment is a vital component of career guidance and counseling. Ensuring fair and ethical assessment practice is, however, complex and challenging in a diverse multicultural setting such as South Africa. A myriad of factors—including culture, and language—may moderate individual performance on career interest assessments. For this reason, it is imperative to acknowledge these factors when developing career interest assessments in the South African context. Particular attention was paid to the issues of language and culture during the recent development of the South African Career Interest Inventory (SACII) and South African Career Interest Inventory-isiXhosa version (SACII-X). In this paper, we discuss some of the crucial considerations that informed the conceptualization and development of the SACII-X. The promising initial reliability and validity demonstrated by these assessments provide support for the use of career assessments based on imported career theories if sensitivity is afforded to contextual, language, and cultural considerations during the development of such assessment measures.
Factors Affecting Employee’s Retention: Integration of Situational Leadership With Social Exchange Theory
Authors: Xuecheng Wei , Iqbal Qaisar , Saina Bai
Published: July 2022

Sketching on the Social Exchange Theory (SET), the present study aims to investigate the direct relationship between training and development, work environment, and job satisfaction with employee retention. The contingent role of transformational leadership was also analysed under the Situational Leadership Theory (SLT). Accordingly, we collected data from 287 employees of SMEs in northern China by employing a convenience sampling approach, exhibiting a response rate of 57.40 percent. The Partial Least Square-Structural Equation Modelling (PLS-SEM) analysis was then run to test the proposed hypotheses. The findings revealed a significant positive impact of training and development, work environment, and job satisfaction on employee retention. However, no moderating effect of transformational leadership was indicated on their direct relationship. This study has enriched the literature on employee retention and the leadership arena. To the best of the authors’ knowledge, there is no prior evidence concerning the study’s integrated relationship of the continuous variables. The implications and limitations were finally expressed at the end of this manuscript.
Interpreters as Vital (Re)Tellers of China’s Reform and Opening-Up Meta-Narrative: A Digital Humanities (DH) Approach to Institutional Interpreters’ Mediation
Authors: Gu Chonglong
Published: July 2022

If the important role of written translation in the construction and contestation of knowledge and narratives remains largely under-explored, then the part played by interpreting and interpreters is even less examined in knowledge construction and story-telling. At a time when Beijing increasingly seeks to bolster its discursive power and have the Chinese story properly told, the interpreter-mediated and televised Premier-Meets-the-Press conferences constitute a typical discursive event andregime of truthin articulating China’s officially sanctioned “voice.” Discursive in nature, the institutionalised event permits Beijing to construct a desired version of truth, fact and narrative in front of the more vociferous and dominant West. As an attempt to employ digital humanities (DH) methods to real-world language use, this corpus-based CDA study explores the press conference interpreters’ agency and mediation in rendering key concepts and discourses (e.g., ECONOMY and REFORM) constitutive of the broader Reform and Opening-up meta-narrative, which legitimises China’s political and economic systems, developments, policies and positions in the post-1978 era. The interpreters are found to maintain and often further reinforce Beijing’s discourse in English at various levels. Apart from indicating issues of institutional alignment, this study points to interpreters’ agency in communicating beyond national borders, (re)constructing political and institutional knowledge, counterbalancing the naturalised and taken-for-granted Western narratives, and contributing to the shifting East-West power differentials discursively. This study highlights the significance of interpreters as indispensable (re)tellers of the Chinese story in an increasingly mediat(is)ed world, where the interpreted discourse is routinely quotedverbatimon various platforms and taken for granted as the correct version of Beijing’s official “voice.”

Motivation for bodily movement, physical activity and exercise varies from moment to moment. These motivation states may be “affectively-charged,” ranging from instances of lower tension (e.g., desires, wants) to higher tension (e.g., cravings and urges). Currently, it is not known how often these states have been investigated in clinical populations (e.g., eating disorders, exercise dependence/addiction, Restless Legs Syndrome, diabetes, obesity) vs. healthy populations (e.g., in studies of motor control; groove in music psychology). The objective of this scoping review protocol is to quantify the literature on motivation states, to determine what topical areas are represented in investigations of clinical and healthy populations, and to discover pertinent details, such as instrumentation, terminology, theories, and conceptual models, correlates and mechanisms of action. Iterative searches of scholarly databases will take place to determine which combination of search terms (e.g., “motivation states” and “physical activity”; “desire to be physically active,” etc.) captures the greatest number of relevant results. Studies will be included if motivation states for movement (e.g., desires, urges) are specifically measured or addressed. Studies will be excluded if referring to motivation as a trait. A charting data form was developed to scan all relevant documents for later data extraction. The primary outcome is simply the extent of the literature on the topic. Results will be stratified by population/condition. This scoping review will unify a diverse literature, which may result in the creation of unique models or paradigms that can be utilized to better understand motivation for bodily movement and exercise.
Consumer Perceptions of Brand Localness and Globalness in Emerging Markets: A Cross-Cultural Context
Authors: Safeer Asif Ali , Zhou Yewang , Abrar Muhammad , Luo Fang
Published: July 2022

The globalization of markets and consumer behavior has changed dramatically in recent years. Similarly, global and local brands are facing many challenges in emerging markets. Thus, in this backdrop, this research is intended to examine the impact of consumer perceptions of brand localness and globalness on brand attitude in order to predict consumer behavioral intentions (purchase intention, price premium, and word of mouth) in cross-cultural emerging markets (China and Pakistan). Additionally, this research considered the moderating effects of consumer ethnocentrism and brand familiarity as a control variable. This study used an online survey to examine 1,562 responses from Chinese (n = 768) and Pakistani (n = 794) consumers regarding local and global brands. The proposed hypotheses were analyzed by using the partial least square-structural equation modeling method. The findings indicated that the consumer perceptions of brand localness and brand globalness had a substantial impact on brand attitude, which in turn favorably influenced consumer behavioral intentions in China and Pakistan. The brand attitude was a crucial mediator in both markets but was more critical in China than Pakistan. The interaction moderating effects of consumer ethnocentrism and consumer perceptions of brand localness positively influenced brand attitude in China, whereas consumer ethnocentrism and consumer perceptions of brand globalness negatively influenced brand attitude in Pakistan. Interestingly, brand familiarity was discovered a substantial control variable in both markets, except for purchase intention in Pakistan. This research contributed to Fishbein’s attitude theory and social identity theory. This research offers important recommendations to local and global marketers and brand managers in formulating and employing several positioning, market segmentation, and targeting strategies that may assist them in competing effectively in emerging markets.
Associations Between Six Core Processes of Psychological Flexibility and Functioning for Chronic Pain Patients: A Three-Level Meta-Analysis
Authors: Ding Dongyan , Zheng Mengna
Published: July 2022

The previous research showed contradictions in the relationships between psychological flexibility processes and functioning. This meta-analysis is the first to provide a comprehensive meta-analysis of the associations between six core processes of psychological flexibility and functioning among chronic pain patients. Four databases were searched (PsycINFO; PubMed; CINAHL; Web of Science) along with reference lists. Thirty-six cross-sectional studies were included (7,812 chronic pain patients). A three-level meta-analytic model was used to examine the associations. The publication bias was assessed with the Egger test, funnel plot, and p-curve analysis. Significant associations were found between functioning and six processes of psychological flexibility (i.e., acceptance, defusion, present moment, committed action, self as context, and values). Except for the relationship between defusion and functioning, the relationships between the other five psychological flexibility processes and functioning were all moderated by domains of functioning. No moderators were found regarding age, percentage of females, country, or type of instrument used to measure functioning. These findings may carry significant implications for chronic pain patients and clinical workers. It might be more effective to focus on functioning-related psychological flexibility processes rather than all therapy packages if the relationships between functioning and specific processes of psychological flexibility were better informed. Limitations were also discussed.

Authors: Li Junping , Guo Jiaoyang , Zhao Juan , Guo Yan , Chen Cheng
Published: July 2022

Objective

To investigate dentists’ psychological status and influencing factors in Shaanxi Province during the COVID-19 epidemic and assess their perceived wellness.

Methods

The study was conducted among dentists from Shaanxi Province in China. The basic information was collected through the network questionnaire star platform. Depression, Anxiety, and Stress Scales (DASS-42) and Perceived Wellness Survey (PWS) were used to assess subjects’ psychological status and perceived wellness. Univariate linear regression analysis and multivariate analysis were performed on the influencing factors of depression, anxiety, and stress, and t-test and analysis of variance were used to analyze the perceived wellness results.

Results

The results demonstrated that 33.2% of the surveyed dentists were in a state of depression, 37.1% were anxious, and 34.4% reported stress among 256 subjects. Linear Regression analysis results showed that: “years of working,” “the impact of COVID-19 on their life, work, and sleep,” “worrying about occupational exposure/virus infection,” “lacking the awareness of prevention and control measures,” “overtime work during the epidemic,” “worrying about participating in the supporting work,” and “continuous exhaustion from work” were significant contributors to depression, anxiety, and stress status. In addition, the results of PWS found that each dimension of PWS was correlated with depression, anxiety, and stress state, which indicates the individual’s physical and mental health state was associated with multiple factors.

Conclusion

COVID-19 has significantly impacted dentists’ mental health in Shaanxi Province. With these findings, we aim to educate and promote targeted interventions that can be utilized to improve dentists’ mental health by analyzing the influencing factors.

Published: July 2022

To date in Cyprus, there is no dedicated “Quality Improvement” body or Public Health authority. The long-awaited general healthcare system (known as GeSy or GHS) has been completed, mid-stream of the COVID-19 pandemic. A recently proposed resilience plan in response to the lessons learnt from the pandemic was put forward by the Government of the Republic of Cyprus to strengthen the capacity of the GHS and support public health defense. The negotiator of GeSy and Health Minister 2015–2018 also provided his view that the health system needs a holistic transformation of service provision. Recognizing failures and thinking from a syndemogenesis perspective how the envisioned patient-centric healthcare delivery can be achieved, we propose that the public health response could also be linked to a politico-economic one in shielding GeSy. We make such case for a syndemic strategy (simultaneous management of COVID-19 and pre-existing epidemics on the island) and the development of the five-district model where each main district hospital is to complement the activities of the GHS through developing: 1. A training Center for training and sharing of best practices for COVID-19 and other public emergencies. 2. A public health body. 3. A quality improvement institute. 4. A commissioning center on planning and streamlining healthcare services. 5. A clinical trial platform. The rationale is based on the management literature and use of existing resources and capabilities for transforming the GeSy and generating value.
Oral Adverse Events Following COVID-19 Vaccination: Analysis of VAERS Reports
Authors: Riad Abanoub , Põld Ave , Kateeb Elham , Attia Sameh
Published: July 2022

Background

Oral adverse events (AEs) following COVID-19 vaccination have been sporadically reported during the previous months, warranting further investigation for their prevalence and suspected relationship with vaccine-elicited immune response.

Methods

A retrospective analysis using the Vaccine Adverse Event Reporting System (VAERS) data was conducted to evaluate AEs within the oral cavity (mucosa, tongue, lips, palate, dentition, salivary glands) and AEs involving taste and other sensations. Oral AEs reported after receiving COVID-19 vaccination (test group) and seasonal influenza vaccination (control group) were extracted and cross-tabulated to assess their relative prevalence.

Results

Among the 128 solicited (suspected) oral AEs, oral paresthesia (0.872%) was most reported after receiving COVID-19 vaccines, followed by the swelling of lips (0.844%), ageusia (0.722%), oral hypoesthesia (0.648%), swollen tongue (0.628%), and dysgeusia (0.617%). The reported prevalence of oral AEs was higher in the COVID-19 vaccine group than in the seasonal influenza group. The distribution pattern of the most reported oral AEs was similar for both COVID-19 and seasonal influenza vaccines. Female sex, older age (>39 years old), primer doses, and mRNA-based COVID-19 vaccines exhibited a higher reported prevalence of oral AEs.

Conclusion

Within the limitations of this study, COVID-19 vaccines were found to be associated with rare oral AEs that are predominantly similar to those emerging following seasonal influenza vaccines. The most commonly reported oral AEs were oral paraesthesia (mouth-tingling), lip swelling, and ageusia, representing various pathophysiologic pathways that remain unclear. Taste-related AEs should be acknowledged in the context of the COVID-19 pandemic and the public should be adequately informed about a potential taste dysfunction after receiving the COVID-19 vaccination. Dentists and dental teams need to be aware of the prevalence, severity, and prognosis of oral AEs to inform their patients and increase public confidence in vaccines.
Design Optimization for Rough Terrain Traversal Using a Compliant, Continuum-Joint, Quadruped Robot
Authors: Sherrod Vallan , Johnson Curtis C. , Killpack Marc D.
Published: July 2022

Legged robots have the potential to cover terrain not accessible to wheel-based robots and vehicles. This makes them better suited to perform tasks such as search and rescue in real-world unstructured environments. In addition, pneumatically-actuated, compliant robots may be more suited than their rigid counterparts to real-world unstructured environments with humans where unintentional contact or impact may occur. In this work, we define design metrics for legged robots that evaluate their ability to traverse unstructured terrain, carry payloads, find stable footholds, and move in desired directions. These metrics are demonstrated and validated in a multi-objective design optimization of 10 variables for a 16 degree of freedom, pneumatically actuated, continuum joint quadruped. We also present and validate approximations to preserve numerical tractability for any similar high degree of freedom optimization problem. Finally, we show that the design trends uncovered by our optimization hold in two hardware experiments using robot legs with continuum joints that are built based on the optimization results.
How the Environment Shapes Tactile Sensing: Understanding the Relationship Between Tactile Filters and Surrounding Environment
Authors: Costi Leone , Maiolino Perla , Iida Fumiya
Published: July 2022

The mechanical properties of a sensor strongly affect its tactile sensing capabilities. By exploiting tactile filters, mechanical structures between the sensing unit and the environment, it is possible to tune the interaction dynamics with the surrounding environment. But how can we design a good tactile filter? Previously, the role of filters’ geometry and stiffness on the quality of the tactile data has been the subject of several studies, both implementing static filters and adaptable filters. State-of-the-art works on online adaptive stiffness highlight a crucial role of the filters’ mechanical behavior in the structure of the recorded tactile data. However, the relationship between the filter’s and the environment’s characteristics is still largely unknown. We want to show the effect of the environment’s mechanical properties on the structure of the acquired tactile data and the performance of a classification task while testing a wide range of static tactile filters. Moreover, we fabricated the filters using four materials commonly exploited in soft robotics, to merge the gap between tactile sensing and robotic applications. We collected data from the interaction with a standard set of twelve objects of different materials, shapes, and textures, and we analyzed the effect of the filter’s material on the structure of such data and the performance of nine common machine learning classifiers, both considering the overall test set and the three individual subsets made by all objects of the same material. We showed that depending on the material of the test objects, there is a drastic change in the performance of the four tested filters, and that the filter that matches the mechanical properties of the environment always outperforms the others.
The Impacts of Climate Change on Land Hydroclimatology of the Laurentian Great Lakes Basin

Published: July 2022

The freshwater resources of the Laurentian Great Lakes basin contribute significantly to the environment and economy of the region. With the impacts of climate change becoming more evident, sustainable management of the freshwater resources of the Laurentian Great Lakes basin is important. This study uses 36 simulations from 6 regional climate models to quantify trends and changes in land-area precipitation and temperature in two future periods (mid-century, 2035–2064 and end-century, 2065–2094) with reference to a baseline period (1951–2005) for two emission scenarios (RCP4.5 and RCP 8.5). Climatic forcings from these 36 simulations are used as input to a calibrated and validated hydrological model to assess changes in land snowpack and actual evapotranspiration, and runoff to lake. Ensemble results show wetter (7 to 15% increase in annual precipitation) and warmer (2.4–5.0°C increase in annual mean temperature) future conditions on GL land areas. Seasonal and monthly changes in precipitation and mean temperature are more sporadic, for instance although precipitation is projected to increase overall, in some scenarios, summer precipitation is expected to decrease. Projected increases in highest one-day precipitation and decreases in number of wet days indicate possible increases in extreme precipitation in future. Minimum temperature is expected to increase in a higher rate than maximum temperature. Ensemble results from the hydrological model show projected decrease in snowpack (29–58%). Similarly, actual evapotranspiration is projected to increase, especially during summer months (up to 0.4 mm/day). Annually, runoff is expected to increase (up to 48% in Superior, 40% in Michigan-Huron, 25% Erie and 28% in Ontario). Seasonal and monthly changes in runoff are more sporadic (e.g., projected decrease up to 17% in Erie subdomain in October). Such contrasting patterns of changes in land hydroclimatology of the GL basin will pose challenges to sustainable management of the water resources of the basin in future.
Mini-Percutaneous Nephrolithotomy With an Endoscopic Surgical Monitoring System for the Management of Renal Stones: A Retrospective Evaluation
Authors: Gui Huiming , Wang Hanzhang , Kaushik Dharam , Rodriguez Ronald , Wang Zhiping
Published: July 2022

Purpose

To compare the outcomes and postoperative quality of life of patients with renal calculi who underwent standard percutaneous nephrolithotomy (sPNL), mini-invasive percutaneous nephrolithotomy (mPNL) or mPNL with an endoscopic surgical monitoring system (ESMS) using a retrospective clinical trial.

Methods

Eighty-six adult patients with renal stones who were treated with sPNL were retrospectively compared to ninety-two patients who were treated with mPNL between July 2014 and December 2017. Next, further studies were retrospectively conducted using a matched paired method. The ninety-two patients treated with mPNL were divided into two groups based on whether the endoscopic surgical monitoring system (ESMS) was used (ESMS-mPNL vs. non-ESMS-mPNL). The ESMS used strain gauge transducers to measure the inflow and outflow of irrigation solution. Bleeding and fluid absorption during endoscopic surgery could be accurately calculated by computer program in ESMS.

Results

The fluoroscopy time, complication rate, stone-free status and clinically insignificant residual fragment (CIRF) rate were not significantly different between the two groups (sPNL vs. mPNL). The mPNL group had a significantly longer operation time than the sPNL group, and the mPNL group exhibited a markedly reduced 12-h postoperative visual analogue pain scale (VAS) score, mean hospitalization time, and return to work time, had slightly reduced haemoglobin loss, and underwent more tubeless operations. Moreover, among the 92 patients who underwent mPNL, the operation time (P = 0.090), complication rate (P = 0.996), stone-free status (P = 0.731), CIRF rates (P = 0.125) and number of tubeless operations (P = 0.760) were not significantly different between the two subgroups (non-ESMS-mPNL vs. ESMS-mPNL); however, the patients in the ESMS-mPNL group had significantly longer irrigation times than those in the non-ESMS-mPNL subgroup, along with marked reductions in irrigation fluid, blood loss, haemoglobin loss, 12 h postoperative VAS score, mean hospitalization time, and return to work time.

Conclusions

mPNL is less painful than sPNL in patients undergoing treatment for 20–40 mm renal stones. Similar stone-free rates were achieved by the two procedures, but mPNL was superior to sPNL in terms of blood loss, discomfort, hospitalization time and return to work time. We think that ESMS-mPNL is less painful for patients and more efficacious than non-ESMS-mPNL, and ESMS-mPNL achieves a stone-free rate that is similar to non-ESMS-mPNL in patients receiving treatment for 20–40 mm kidney stones.
Perioperative Inflammatory Response and Cancer Recurrence in Lung Cancer Surgery: A Narrative Review
Authors: Choi Hoon , Hwang Wonjung
Published: July 2022

While surgical resection is the gold standard treatment for solid tumors, cancer recurrence after surgery is common. Immunosurveillance of remnant tumor cells is an important protective mechanism. Therefore, maintenance of anti-tumor cell activity and proper levels of inflammatory mediators is crucial. An increasing body of evidence suggests that surgery itself and perioperative interventions could affect these pathophysiological responses. Various factors, such as the extent of tissue injury, perioperative medications such as anesthetics and analgesics, and perioperative management including transfusions and methods of mechanical ventilation, modulate the inflammatory response in lung cancer surgery. This narrative review summarizes the pathophysiological mechanisms involved in cancer recurrence after surgery and perioperative management related to cancer recurrence after lung cancer surgery.
Correlation Between Serum β2-GPI/oxLDL and the Risk of Cerebral Infarction in Patients with T2DM
Authors: Kuang Wending , Li Yi , Liu Gang , Zhang Yang , Chen Gang , Luo Bang , Kuang Shuangyu
Published: July 2022

Objective

This study aims to study the correlation between serum β2-glycoprotein I (β2-GPI)/oxidized low-density lipoprotein (oxLDL) and the risk of cerebral infarction in patients with type 2 diabetes (T2DM).

Methods

From January 2019 to March 2021, 56 patients with T2DM combined with cerebral infarction were chosen as a diabetic cerebral infarction (DCI) group, and 60 patients with simple T2DM were chosen as a T2DM group. In addition, 60 healthy volunteers were recruited as a control group. The essential information of each group was collected, and the serum β2-GPI/oxLDL and inflammatory factor levels in each group were compared. The clinical factors that affect the risk of ischemic cerebral infarction in patients with T2DM were analyzed by a logistic model.

Results

Compared with the control group, the level of serum β2-GPI/oxLDL in the T2DM and DCI groups increased significantly, P < 0.001. Compared with the T2DM group, the serum β2-GPI/oxLDL level in the DCI group increased significantly, P < 0.05. The result of Pearson’s correlation analysis showed that serum β2-GPI/oxLDL was positively correlated with total cholesterol, triglycerides, fasting blood glucose, 2-h postprandial blood glucose, glycosylated hemoglobin, interleukin-6, and tumor necrosis factor (TNF)-α (all P’s < 0.05). Serum TNF-α and β2-GPI/oxLDL were independent risk variates for DCI (P < 0.05). Based on the receiver operating characteristic curve analysis, the values of the area under the curve for TNF-α, serum β2-GPI/oxLDL, and the combined diagnosis of DCI were 0.653 (0.552–0.753), 0.680 (0.583–0.777), 0.739 (0.647–0.831), respectively.

Conclusion

In DCI patients, the levels of serum oxLDL/β2-GPI are significantly increased. Serum oxLDL/β2-GPI is an independent risk factor that affects the occurrence of DCI. In addition, the serum β2-GPI/oxLDL level implicates the lipid metabolism and inflammatory status of the internal environment of DCI patients to a certain extent.
The Liberal Social Values of Swedish Healthcare Providers in Women’s Healthcare: Implications for Clinical Encounters in a Diversified Sexual and Reproductive Healthcare
Authors: Eriksson Lise , Tibajev Andrey , Vartanova Irina , Strimling Pontus , Essén Birgitta
Published: July 2022

Objectives: Women’s healthcare is a potential source of cross-cultural conflicts. Diverging values between healthcare providers and patients challenges the provision of culturally sensitive care and meeting migrant women’s needs. The aim is to investigate healthcare providers’ values in relation to sexual and reproductive rights, gender equality, migration and religion in Swedish sexual and reproductive healthcare.

Methods: A national cross-sectional study was carried out. The questionnaire was distributed through a non-probability sample to midwives or other nurses, gynaecologists and obstetricians, and hospital social workers (n = 1,041). Through descriptive statistics, we mapped their values, comparing healthcare provider data to external representative population survey data.

Results: Healthcare providers in sexual and reproductive healthcare displayed homogeneous liberal social values, being permissive towards sexual and reproductive rights and restrictive against gender-based violence. They were for gender equality, expressed low anti-immigrant sentiments, and had even more liberal values than the Swedish population and a demographically comparative sub-population.

Conclusion: Individuals with very liberal values are selected to work in Swedish sexual and reproductive healthcare. Healthcare providers need self-reflexivity to avoid conflicts in clinical encounters in a diversified society.
The therapeutic alliance in acceptance and commitment therapy
Authors: Robyn D. Walser  , Manuela O’Connell
Published: July 2022

Acceptance and Commitment Therapy (ACT) is a process-based intervention that promotes psychological flexibility by implementing six core processes. These include acceptance and awareness as well values and behavior change processes. Still, the primary vehicle for implementing these processes is the therapeutic relationship. Underscoring the importance of the relationship is paramount – it is the context in which the interventions emerge, allowing the therapist to shape psychological flexibility directly. We argue that the therapeutic alliance (TA) is co-created and is a critical factor contributing to the effectiveness of ACT. This paper focuses on the TA as a vital part of ACT treatment. We discuss the therapeutic alliance from an ACT perspective, explore different roles in implementing ACT, and conclude with a clinical case illustration. We more specifically focus on how the TA alliance and the therapeutic relationship can be a vehicle of change in ACT.
Acceptance and commitment therapy focused on repetitive negative thinking for complicated breakup grief: A randomized multiple-baseline evaluation
Authors: Diana P. Medina-Reina  , Francisco J. Ruiz
Published: July 2022

Romantic relationship breakups often cause important behavioral and emotional consequences that can lead to experiencing complicated grief. However, little empirical research has tested psychological interventions for this frequent problem. This preliminary study explored the efficacy of a three-session protocol of Acceptance and Commitment Therapy (ACT) focused on repetitive negative thinking (RNT) for the treatment of complicated breakup grief in three women. A nonconcurrent, across participant, randomized multiple-baseline design was conducted. The three participants showed very large decreases in breakup distress that surpassed the criteria for claiming clinically significant changes. Two participants showed clinically significant changes in emotional symptoms, and all of them attained significant changes in life satisfaction. All three participants showed clinically significant changes in repetitive negative thinking, experiential avoidance, cognitive fusion, and valued living. Effect sizes comparable across designs were very large and statistically significant for breakup distress (d = 7.11), emotional symptoms (d = 2.46), and life satisfaction (d = 1.25). In conclusion, RNT-focused ACT protocols might be efficacious in cases of complicated breakup grief.

Published: July 2022

The croton scale Phalacrococcus howertoni Hodges & Hodgson gen. nov., sp. nov. (Hemiptera: Coccidae), was first found in Florida, USA. This scale has become a pest because of its high reproductive rate and production of sooty mold. Here, we evaluated predation potential of the predatory beetle, Thalassa montezumae Mulsant (Coleoptera: Coccinellidae), as a biological control agent. To our knowledge, this is the first study of predation by T. montezumae on P. howertoni. Results of our studies showed that the predation by 4th instar T. montezumae was higher on 2nd stage nymphs than on 3rd stage nymphs P. howertoni; predation on adults was lowest. Mean consumption by adult T. montezumae was highest on 2nd stage nymphs followed by 3rd stage nymphs, and adult P. howertoni. There were no significant differences between male and female adult T. montezumae in the prey first visited when offered a choice of 2nd or 3rd instar nymphs, or adults of P. howertoni. Thus, the levels of acceptance did not vary significantly between stages of prey visited by the males and females. Females chose prey faster than males and used less energy to search for food. Egg fecundity did not vary among female beetles fed with different stages of croton scales. Should P. howertoni become a major pest, T. montezumae could be used as a biological control agent within a biologically based integrated pest management program.

The existence of dockage, unripe kernels, and foreign materials in chickpea mixtures is one of the main concerns during chickpea storage and marketing. Novel algorithms based on image processing were developed to detect undesirable, foreign materials, and matured chickpea kernels in the chickpea mixture. Images of 270 objects including 54 sound samples and 36 samples of each undesired object were prepared and features of these acquired images were extracted. Different models based on linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural networks (ANN) methods were developed by using MATLAB. Three classification algorithms based on LDA, SVM, and ANN methods were developed. The classification accuracy in training, testing, and overall detection showed the superiority of ANN (99.4, 92.6, and 94.4%, respectively) and LDA (91.1, 94.0, and 91.9%, respectively) over the SVM (100, 53.7, and 88.5%, respectively). The developed image processing technique can be incorporated with a vision-based real-time system.
Efficiently Detecting Non-Stationary Opponents: A Bayesian Policy Reuse Approach under Partial Observability

In multi-agent domains, dealing with non-stationary opponents that change behaviors (policies) consistently over time is still a challenging problem, where an agent usually requires the ability to detect the opponent’s policy accurately and adopt the optimal response policy accordingly. Previous works commonly assume that the opponent’s observations and actions during online interactions are known, which can significantly limit their applications, especially in partially observable environments. This paper focuses on efficient policy detecting and reusing techniques against non-stationary opponents without their local information. We propose an algorithm called Bayesian policy reuse with LocAl oBservations (Bayes-Lab) by incorporating variational autoencoders (VAE) into the Bayesian policy reuse (BPR) framework. Following the centralized training with decentralized execution (CTDE) paradigm, we train VAE as an opponent model during the offline phase to extract the latent relationship between the agent’s local observations and the opponent’s local observations. During online execution, the trained opponent models are used to reconstruct the opponent’s local observations, which can be combined with episodic rewards to update the belief about the opponent’s policy. Finally, the agent reuses the best response policy based on the updated belief to improve online performance. We demonstrate that Bayes-Lab outperforms existing state-of-the-art methods in terms of detection accuracy, accumulative rewards, and episodic rewards in a predator–prey scenario. In this experimental environment, Bayes-Lab can achieve about 80% detection accuracy and the highest accumulative rewards, and its performance is less affected by the opponent policy switching interval. When the switching interval is less than 10, its detection accuracy is at least 10% higher than other algorithms.

In recent years, the use of hop extracts in industrial and home brewing processes as an alternative to hop cones or pellets usually added to wort during boiling has become increasingly popular. These extracts represent concentrated sources of bitter compounds, i.e., α- and β-acids, which are involved in some of the main reactions that take place in the wort and are responsible for the bitterness and the final quality of beer. This work aims at proposing a novel extraction technique, using a hydrofluorocarbon solvent in subcritical conditions; this process provided an extraction yield of 19% and an α-acid recovery of approximately 49% in 120 min of process. The α-acid isomerization kinetics of thermally treated hop extracts were studied and compared with those of both hop pellets and a CO2 extract. Laboratory scale tests showed that shorter boiling times were needed using hydrofluorocarbon and CO2 extracts (approximately 25 min and 34 min, respectively) to reach the same isomerization efficiency of 16.73%, achieved in 50 min of boiling with pellets. Moreover, the process was scaled up and the possibility of considerably reducing the conventional treatment times using hydrofluorocarbon extracts was confirmed: the same isomerization yield (9.1%) obtained after 50 min using the traditional procedure with hop pellets was reached in a shorter time of approximately 35 min in a pilot apparatus.

In the process of grab dredger dredging, how to ensure the accuracy of flat digging is a key technical question. The accuracy of flat digging is related to the force of grab digging. However, there are limitations in the traditional method of studying the force of grab digging. In this study, based on the Rankine theory, the unit integration method is proposed to calculate the force process of grab excavation. This method determines the shape and position of the failure surface under the action of active pressure FB and passive pressure FE and further obtains a functional expression for the relation between digging force and digging parameters. Through the simulation of flat digging force using the discrete element method (DEM), we obtained results consistent with the calculation results of the unit integration method. In addition, this study sought to control the movement distance of the closing wires and the hoist wires through the equation of motion, to carry out the precision calculations of theoretical data, and experimental research into grab flat digging. By comparing theoretical data and test data, the following conclusion was drawn: the deviation of the theoretical flat digging precision from the test data falls within the allowable range, at 3.15%. This study provides technical support for the flat digging process of the grab dredger.

Published: July 2022

In the present study, large-scale specimens based on the tunnel prototype were prepared and static load tests were carried out to investigate the damage caused by lining voids. Based on the strengthening scheme of the tunnel, the strengthened specimens were prepared to explore the strengthening effect on the strengthening structure. The strengthening structure is made of a steel plate fixed with chemical anchor bolts and two-component epoxy adhesive. By analyzing the failure mode, structural deformation, and the relationship between load and strain, the damage caused by vault void with various void heights was analyzed and the obtained results were verified through the experiment. Moreover, the enhancement of the bearing capacity and stiffness of the structure strengthened by surface bonding steel was studied. The obtained results show that the damage caused by the lining void mainly occurs at the void boundary. The damage appears as multiple longitudinal cracks. The crack starts from the lower surface and develops radially. Using chemical anchor bolts and two-component epoxy adhesive to bond the steel plate on the lining surface, the damage can be reduced, and the bearing capacity of the structure can be improved effectively when the void height is a quarter of the second lining thickness, the number of cracks is reduced from 14 to 5 after steel plate strengthening, and the length of the longest crack is reduced from 13.2 cm to 8.3 cm, reduced by 37.12%. The steel plate strengthening also reduces the strain of the lower steel bar at the void boundary from 1130.58 με to 555.12 με, and the strain decreases by 50.89%. The experimental results show that the position where the void has the greatest impact on the lining is at the void boundary. Therefore, when steel plates are used to strengthen the void lining, the void boundary should be emphasized, which makes the strengthening more accurate and saves the cost of treatment.

Published: July 2022

Edge detection is a fundamental step in many computer vision systems, particularly in image segmentation and feature detection. There are a lot of algorithms for detecting edges of objects in images. This paper proposes a method based on local gradient estimation to detect metallic droplet image edges and compare the results to a contour line obtained from the active contour model of the same images, and to results from crowdsourcing to identify droplet edges at specific points. The studied images were taken at high temperatures, which makes the segmentation process particularly difficult. The comparison between the three methods shows that the proposed method is more accurate than the active contour method, especially at the point of contact between the droplet and the base. It is also shown that the reliability of the data from the crowdsourcing is as good as the edge points obtained from the local gradient estimation method.
