Multi-dimensional resource allocation strategy for LEO satellite communication uplinks based on deep reinforcement learning
Authors: Hu Yu , Qiu Feipeng , Zheng Fei , Zhao Jilong 
Published: March 2024

AbstractIn the LEO satellite communication system, the resource utilization rate is very low due to the constrained resources on satellites and the non-uniform distribution of traffics. In addition, the rapid movement of LEO satellites leads to complicated and changeable networks, which makes it difficult for traditional resource allocation strategies to improve the resource utilization rate. To solve the above problem, this paper proposes a resource allocation strategy based on deep reinforcement learning. The strategy takes the weighted sum of spectral efficiency, energy efficiency and blocking rate as the optimization objective, and constructs a joint power and channel allocation model. The strategy allocates channels and power according to the number of channels, the number of users and the type of business. In the reward decision mechanism, the maximum reward is obtained by maximizing the increment of the optimization target. However, during the optimization process, the decision always focuses on the optimal allocation for current users, and ignores QoS for new users. To avoid the situation, current service beams are integrated with high- traffic beams, and states of beams are refactored to maximize long-term benefits to improve system performance.Simulation experiments show that in scenarios with a high number of users, the proposed resource allocation strategy reduces the blocking rate by at least 5% compared to reinforcement learning methods, effectively enhancing resource utilization.

Abstract
Background
Schools are an ideal setting for enhancing mental health literacy, a crucial strategy for improving adolescents’ mental health knowledge and attitudes and promoting help-seeking. "The Guide Cymru" program is an adaptation of the mental health literacy program" The Guide" that was developed in Canada. The program will be culturally adapted for 13- to 15-year-old Iranian adolescent students in the first secondary schools.

Methods
In this randomized controlled trial, using the stratified random sampling procedure, the whole eighth and ninth grade student body (aged 13 to 15) from Sirjan City's first secondary schools will be included in the study. Twenty first secondary schools will be randomly assigned to one of two groups: control or intervention. Finally, 562 students and 40 teachers will participate in the research. The tools of mental health literacy scale (MHLs), mental health general knowledge and attitudes related to mental disorders/illnesses are employed in this study.

Discussion
This trial aims to be to explore whether "The Guide Cymru", a mental health literacy program offered to students as part of the school curriculum, can decrease the stigma associated with mental health and promote help-seeking behaviors among students.
Childhood maltreatment and psychopathy in Chinese juvenile offenders: person-centered perspective
Authors: Yang Yuanhua , Yu Jie , Zhang Suxian , Xie Qing 
Published: March 2024

Abstract
Background
Childhood maltreatment stands as a salient risk factor in the etiology of juvenile delinquency, with a profound impact on the behavioral trajectories of young offenders. However, there is limited research on latent profile analysis to explore distinctive patterns of childhood maltreatment in Chinese juvenile offenders. Consequently, there is a lack of understanding regarding the associations between maltreatment profiles and relevant variables in this context. The present study aimed to explore meaningful subgroups of childhood maltreatment in juvenile offenders, and we further examined the associations between subgroups and multiple outcomes especially psychopathy.

Methods
The data was obtained from a sample of Chinese juvenile offenders (N = 625, M age = 17.22, SD = 1.23). This study employed a latent profile analysis (LPA) based on factor scores of the Childhood Trauma Questionnaire-Short Form to identify the subgroups and examined the differences across subgroups using outcomes variables including psychopathy, callous-unemotional traits, aggression and anxiety. This study includes three self-report measures to evaluate psychopathy, with due regard for the nuanced considerations on the factor structure inherent in the conceptualization of psychopathy.

Results
Two subgroups were identified, including the non-maltreatment subgroup (80.2%) and the maltreatment subgroup (19.8%). Maltreatment subgroup was characterized by a greater level of all types of maltreatment with particularly higher of emotion neglect. Besides, we found that maltreatment subgroup showed a significantly higher level of psychopathy across multiple self-report measures, and greater callous-unemotional traits, lack of empathy, aggression and anxiety. We found two subgroups of child maltreatment in Chinese juvenile offenders.

Conclusions
These findings may provide a further understanding of childhood maltreatment and the clinical intervention on psychopathy in the early period.
Biodynamic, organic and integrated agriculture effects on cv. Italia table grapes juice, over a 3-year period experiment: an 1H NMR spectroscopy-based metabolomics study
Authors: Colì Chiara Stella , Girelli Chiara Roberta , Cesari Gianluigi , Hussain Mudassar , Fanizzi Francesco Paolo 
Published: March 2024

Abstract
Background
The new trend demanding for “natural” agri-food products has encouraged the application of more sustainable and eco-friendly farming methods, which limit or avoid the use of synthetic chemicals. This approach is increasing in viticulture, one of the sectors with the highest commercial value since grapes and derived products are largely consumed foodstuffs, with appreciated nutritional and sensory features. In this work, 1H Nuclear Magnetic Resonance spectroscopy (1H NMR) was applied for the metabolic profiling of cv. Italia table grapes samples, from the same origin area, cultivated with different treatments (biodynamic, organic and integrated) and collected in three subsequent vintages. Multivariate statistical analysis was performed on NMR-data with the aim of comprehensively researching the possible influences on metabolites due to the use of diverse agricultural practices.

Results
Both inter-annual variability (2020, 2021 and 2022 vintages) and different vineyard treatments (biodynamic, organic and integrated) resulted as significant drivers for samples differentiation in the preliminary unsupervised analysis of the (1H NMR spectra derived) metabolic profile data. Nevertheless, supervised data analyses showed that inter-vineyards variability, due to application of diverse farming methods, had a comparable discriminating effect with respect to harvesting years. Ethanol, sugars (as α-/β-glucose), organic acids (as malate) and amino acids (as arginine, leucine, glutamine) resulted the most viticultural practices-dependent metabolites. Interestingly, results from pairwise comparisons between treatments indicated the biodynamic samples with respect to the organic ones as the best-observed differentiation. This was followed by the biodynamic vs integrated and organic vs integrated samples comparisons, in decreasing discrimination order, as confirmed by the descriptiveness and predictive ability parameters of the corresponding pairwise OPLS-DA models.

Conclusions
Results highlighted that metabolites’ composition in cv. Italia table grapes juice is significantly affected by the use of different kinds of vineyard managements (biodynamic, organic and integrated, here investigated). Metabolomics study, here employing 1H NMR spectroscopy combined with multivariate statistical analysis, offers powerful tools to elucidate the metabolic differences among classes of samples.

Anxiety-provoking factors in consecutive interpreting: a qualitative study of Iranian student interpreter trainees
Authors: Ferdowsi Sima , Razmi Mohammad Hasan 
Published: March 2024

AbstractGiven the inherent association of interpreting with feelings of anxiousness, the subject of interpreting poses a formidable challenge for students in this field. A large number of prospective interpreters assert that they are unable to complete the assignment to a satisfactory level because they are unable to get past their fear. The harmful effect of anxiety on the interpreting performance of student trainees could result in failure and fully inhibit their accomplishment. Despite the growing recognition of anxiety as a significant challenge in interpreting education, there is a lack of comprehensive studies investigating the specific factors contributing to anxiety in consecutive interpreting and effective strategies for its reduction. To address this issue and in order to identify the factors contributing to trainees’ anxiety and those that might help to reduce consecutive interpreting (CI) anxiety, thirty students were chosen to participate in semi-structured interviews. Different factors exerting an effect on the anxiety levels of Iranian CI pupils were identified through qualitative research. These factors were categorized into six groups, i.e., individual, input (language-related factors, speaker-related factors), note- taking (inappropriate note-taking skill, lack of creativity in taking notes), environmental (noise and distraction, peer-related factors), output (meaning transfer, delivery), and teacher-related (testing, teachers’ behavior). Moreover, the study found that factors to reduce anxiety in consecutive interpreting could be classified as teacher-related and trainee-related factors each with additional sub-factors.

Published: March 2024

AbstractThe aim of the study was to investigate whether the content of Corporate Social Responsibility (CSR) messages predicts communication outcomes in South African nonprofit organisations (NPOs). The study found a positive association between CSR message content and CSR communication outcomes. Additionally, CSR message content in nonprofit organisations is positively linked to their CSR communication outcomes. Furthermore, support for community-related activities positively impacts CSR communication outcomes, thereby explaining the correlation between CSR message content and communication effectiveness. The study lays the groundwork for non-profit organisations seeking optimisation of their CSR messaging to achieve a wider socio-economic impact on the public at large. These results underscore the importance for nonprofit organisations to strategically develop CSR messages that highlight their support for community-related activities. By emphasising such content in their communication efforts, organisations can enhance their CSR communication outcomes, potentially fostering stronger relationships with stakeholders and garnering increased support for their initiatives.
Characterizing patient factors, perioperative interventions, and outcomes associated with inpatients falls after total knee arthroplasty

Published: March 2024

Abstract
Introduction
Mechanical falls represent a potential adverse event after total knee arthroplasty (TKA) and may introduce further injury and delay postoperative recovery. This study aimed to identify patient characteristics associated with inpatient falls, to determine the impact of inpatient falls on surgical outcomes following TKA, and to describe the relationship between tourniquet and/or adductor canal block (ACB) use and fall rates.

Methods
Patients undergoing primary, elective TKA at a single institution between 2018 and 2022 were retrospectively analyzed. Patients were stratified into groups based on whether they sustained a postoperative inpatient fall or not. Perioperative characteristics, lengths of stay (LOS), rates of 90-day readmissions, and revisions were compared, and fall characteristics were described. Subanalysis was conducted comparing fall incidence based on tourniquet and/or ACB use.

Results
In total 6472 patients were included with 39 (0.6%) sustaining falls. Falls most commonly occurred on postoperative days one (43.6%) and two (30.8%), and were most commonly due to loss of balance (41.9%) or buckling (35.5%). Six (15.4%) fall patients sustained minor injuries, and one (2.6%) sustained major injury (malleolar fracture requiring non-operative orthopaedic management). The LOS (3.0 ± 1.5 vs 2.3 ± 1.5 days, p = 0.002) and all-cause revision rates at latest follow-up (10.3% vs. 2.0%, p = 0.008) were significantly higher in the fall group. Falls were comparable across subgroups based on tourniquet and/or ACB use (p = 0.429).

Conclusion
Patients who fell had a longer LOS and higher revision rate postoperatively. Rates of inpatient falls were comparable regardless of tourniquet and/or ACB use. Concern for inpatient falls should not influence surgeons when considering the use of tourniquets and/or ACBs, though well-designed, large-volume, prospective randomized studies are warranted to better understand this relationship.
Diagnostic efficacy of abdominal US compared to contrast enhanced CT in the evaluation of the left hepatic lobe volume for morbidly obese patients before bariatric surgery
Authors: Baz Ahmed Abdelrahman , Hussien Amira Mohammed , Soliman Ahmad Fouad , Al-Bohy Abo El-Magd 
Published: March 2024

Abstract
Background
Bariatric surgery has been widely distributed as an effective treatment method for morbid obesity. An increased volume of the left hepatic lobe may affect the ergonomics of bariatric surgery, which could complicate the surgical techniques and require special instruments. CT of the abdomen is considered the gold standard imaging modality in the assessment of the left hepatic lobe volume; nevertheless, it has some drawbacks, such as exposure to ionizing radiation, besides the contrast and gantry limitations. The objective of this study is to investigate the diagnostic accuracy of abdominal US in comparison to CT in measuring the left hepatic lobe volume in morbidly obese patients as part of their preoperative evaluation. Seventy-two morbidly obese patients of different ages (between 22 and 55 years) and genders were included in this study who were scheduled for bariatric surgery.

Results
The intraclass coefficient and Cronbach's alpha reliability coefficient with their 95% CI were used. There was a strong positive correlation between left hepatic lobe volumes as measured by US and CT (r = 0.999, p value < 0.001), indicating a significant linear relationship between them. The mean of the two variables was very close (474.2 ± 164.9 cm3) by US and (475.1 ± 164.5 cm3) by CT.

Conclusions
Abdominal US examination for assessment of the left hepatic lobe volume is considered a valid diagnostic method compared to CT (with a clinically accepted slight difference between values) in preoperative assessment of morbidly obese patients. It provides an accurate, simple, and inexpensive diagnostic tool that avoids the drawbacks of CT.

Published: March 2024

BACKGROUND AND PURPOSE:
A retrospective single-center analysis of the safety and efficacy of reirradiation to 40 Gy in 5 fractions (reSBRT) in patients previously treated with stereotactic body radiotherapy to the spine was performed.

METHODS:
We identified 102 consecutive patients treated with reSBRT for 105 lesions between 3/2013 and 8/2021. Sixty-three patients (61.8%) were treated to the same vertebral level, and 39 (38.2%) to overlapping immediately adjacent levels. Local control was defined as the absence of progression within the treated target volume. The probability of local progression was estimated using a cumulative incidence curve. Death without local progression was considered a competing risk.

RESULTS:
Most patients had extensive metastatic disease (54.9%) and were treated to the thoracic spine (53.8%). The most common regimen in the first course of stereotactic body radiotherapy was 27 Gy in 3 fractions, and the median time to reSBRT was 16.4 months. At the time of simulation, 44% of lesions had advanced epidural disease. Accordingly, 80% had myelogram simulations. Both the vertebral body and posterior elements were treated in 86% of lesions. At a median follow-up time of 13.2 months, local failure occurred in 10 lesions (9.5%). The 6- and 12-month cumulative incidences of local failure were 4.8% and 6%, respectively. Seven patients developed radiation-related neuropathy, and 1 patient developed myelopathy. The vertebral compression fracture rate was 16.7%.

CONCLUSION:
In patients with extensive disease involvement, reSBRT of spine metastases with 40 Gy in 5 fractions seems to be safe and effective. Prospective trials are needed to determine the optimal dose and fractionation in this clinical scenario.
Policy Brief 13: Catalysing the private sector for disaster response and resilience – Case study of the Philippine Disaster Resilience Foundation
Authors: Hans Vanessa , Luz Bill 
Published: March 2024

Extreme weather events, earthquakes, volcanic eruptions and epidemics cause the loss of countless lives and bring disruption to many countries. Governments and humanitarian aid agencies are expected to be at the forefront of preparing for and responding to such disasters.
However, occasionally the scale and impact of some natural disasters are so large that additional resources beyond what governments can provide become necessary. In such cases, efforts may be perceived as insufficient and slow. Resources and efforts need to be augmented in order to provide relief and support to those who need it most.
Could the private sector take a more leading role in pre- and post-disaster efforts? How could a structured, long-term engagement reduce the inevitable integrity risks in high-stress disaster situations involving numerous government, business and international actors?
This Policy Brief looks at how the Philippines Disaster Resilience Foundation (PDRF) has emerged as a leading private-sector coordinator for disaster risk reduction and management.
It illustrates the important role that the private sector can play in responding to – and building resilience to – natural disasters and other humanitarian emergencies. It also showcases how vital it is for good governance, integrity and transparent collaboration to be at the heart of those efforts.

PLANT COMPOSITION AND SOIL PROPERTIES DURING POSTAGROGENIC EVOLUTION IN THE CIS-BAIKAL FOREST-STEPPE ZONE
Authors: Zorina Svetlana Yu. , Sokolova Lada G. , Kazanovsky Sergey G. , Dorofeev Nikolai V. 
Published: March 2024

Purpose. The purpose of the study was to examine the features of the restoration of plant communities and some properties of gray forest soils, including the humus state, during their post-agrogenic transformation in the conditions of the Cis-Baikal forest-steppe zone.
Materials and methods. The study was carried out using the post-agrogenic chronosequences, including arable land, abandoned soils of different ages, and natural cenoses (meadow and forest). Traditional methods of phytocenology were applied to study the plant composition. Mixed soil samples from three trenches were collected from the former arable layer of 0–20 cm. The content of organic carbon (Corg), total nitrogen (N), and the C/N ratio, the pH(H2O) and pH(KCL) values, as well as soil density and the reserves of Corg were determined. The statistical processing of data was performed using One Way ANOVA (Sigma Plot from Windows Version 14.0).
Results. It was shown that plant vegetation being typical for the Baikal forest-steppe zone was recovering after the cessation of plowing. At the same time, the several ruderal species were preserved in the plant composition during a long period. This specific phenomenon could be the cause for inhibition of terminal phytocenoses formation. Along with the change in the vegetation, a significant increase in the organic carbon content was revealed in the soils of chronosequences. At the later stages of post-agrogenic succession the carbon reserves in soil were 1.5 times higher than those in arable soil. The humus content in the soils increased with age of the abandoned lands, but no cardinal changes in its qualitative composition were observed. The data indicated the stable functioning of the system of humus substances in the gray forest soils of the Baikal forest-steppe zone during their post-agrogenic evolution.
Conclusion. The results can be used for the forecast of post-agrogenic soil changes under various scenarios of land use in conditions of the Baikal region.
