Rayleigh–Taylor Flow with Two Interfaces: The Completed Boussinesq Approximation
Authors: Forbes Lawrence K. , Walters Stephen J. , Turner Ross J. 
Published: October 2023

AbstractA system of three horizontal fluid layers is considered, with two interfaces separating them. When the upper fluids are of higher density, the system is unstable and Rayleigh–Taylor instabilities occur, as interfacial disturbances grow with time and the fluids overturn. A linearized solution is presented for the corresponding inviscid problem. It reveals a neutrally stable situation when the fluid densities decrease with height. However, whenever a high density fluid lies above a less dense one, the linearized solution predicts exponential growth of the interface between them. With two interfaces present, several different flow scenarios are possible, depending on the two density ratios between the three fluids The interfacial waves can occur either in a sinuous or a varicose formation. A semi-numerical spectral method is used to obtain nonlinear solutions for three-layer viscous fluids, using a recently-published “Completed Boussinesq Approximation”. These nonlinear results are compared with the linearized inviscid solution and also with interface shapes obtained from an SPH algorithm. Results are shown for sinuous and varicose solution types, and inversion layer flows are discussed.

Published: October 2023

AbstractOver the last decade, Ghana has witnessed its share of energy instability (between 2014 and 2016 and beyond) and crises that worsened its energy fortunes. In the phase of such challenges to energy security in Ghana, efforts have been made to achieve a secure, adequate and affordable energy supply, the study assesses the energy security of SMEs, as well as the coping strategies adopted by SMEs in the Greater Accra Region of Ghana to confront the challenges of ES. The analysis covered 246 respondents selected from over 500 SMEs. The cluster method and simple random sampling approaches were used to select the respondents. Data collected through questionnaires were edited and cleaned to ensure completeness, consistency and legibility. Descriptive, exploratory, and inferential analyses were applied to the data collected from the respondents. The means and Relative Importance Index (RII) were calculated and used to assess the strength of strategies adopted by the SMEs to cope with the challenges of ES. The study concluded that the themes for assessing the ES of the SMEs were ranked in order of affordability, acceptability, efficiency, and with the lowest being availability. In general, it came out that the SMEs did show better performance in ES. The categories of SMS that better cope with the challenges of ES are the wholesale and retail business sectors. Their coping strategies relate to the various strategies available to them; reducing energy consumption, exploiting renewable energy power, reducing energy consumption, using generators, and temporarily suspending business. The strength for coping is limited by the few options thus making the SMEs more vulnerable to achieving ES.
Revisiting Coercion as an Element of Prohibited Intervention in International Law
Authors: Milanovic Marko 
Published: October 2023

AbstractInternational law prohibits states from intervening in the internal and external affairs of other states, but only if the method of intervention is coercive. This Article argues that coercion can be understood in two different ways or models. First, as coercion-as-extortion, a demand coupled with a threat of harm or the infliction of harm, done to extract some kind of concession from the victim state—in other words, an act targeting the victim state's will or decision-making calculus. Second, as coercion-as-control, an action materially depriving the victim state of its ability to control its sovereign choices. This may be done even through acts like cyber operations that the victim state is entirely unaware of. The Article argues that many of the difficulties surrounding the notion of coercion arise as a consequence of failing to distinguish between these two different models.

Published: October 2023

AbstractObjective:To estimate cost savings after implementation of customized electronic duplicate order alerts.Design:Alerts were implemented for microbiology tests at the largest public hospital in Victoria, Australia. These alerts were designed to pop up at the point of test ordering to inform the clinician that the test had previously been ordered and to suggest appropriate reordering time frames and indications.Results:In a 6-month audit of urine culture (our most commonly ordered test) after alert implementation, 2,904 duplicate requesters proceeded with the request and 2,549 tests were cancelled, for a 47% reduction in test ordering. For fecal polymerase chain reaction (PCR), our second most common test, there was a 54% reduction in test ordering. For our most commonly ordered expensive test, hepatitis C PCR, there was a 42% reduction in test ordering: 25 tests were cancelled.Cancelled tests resulted in estimated savings of AU$52,382 (US$33,960) for urine culture, AU$34,914 (US$22,442) for fecal PCR, AU$4,506 (US$2,896) for hepatitis C PCR. For cancelled hepatitis B PCR and Epstein-Barr virus (EBV) and cytomegalovirus (CMV) serology, the cost savings was AU$8,472 (US$5445). The estimated financial cost saving in direct hospital costs for these 6 assays was AU$100,274 (US$67,925) over the 6-month period. Environmental waste cost saving by weight was estimated to be 280 kg. Greenhouse gas footprint, measured in carbon dioxide equivalent emissions for cancelled EBV and CMV serology tests, resulted in a saving of at least 17,711 g, equivalent to driving 115 km in a standard car.Conclusion:Customized alerts issued at the time of test ordering can have enormous impacts on reducing cost, waste, and unnecessary testing.
The improvement effect of food additive analysis in patients with anorexia nervosa
Authors: Yan Xiaoping 
Published: October 2023

BackgroundAnorexia nervosa is a severe psychological disorder, and current treatment of anorexia nervosa relies on psychotherapy and medical nutritional support. The study applied food additives to the relevant treatment, aiming to help improve the patients’ diet.Subjects and MethodsPatients who met the diagnostic criteria of anorexia nervosa were randomly selected and divided into experimental and control groups, with 25 patients in each group. The experimental group received food additive-assisted treatment, while the control group received only conventional treatment. Before and after treatment, the patients’ body mass index (BMI) and height were measured, and eating disorders were assessed using the EDE-Q. The resultant data were analyzed using SPSS22.0.ResultsAfter treatment, the BMI of the experimental group was significantly higher than that before treatment (F=18.42, P<0.05), while the BMI of the control group did not change significantly (F=9.71, P>0.05). In the EDE-Q scale assessment, the experimental group scored lower than the control group in terms of frequency of binge eating, frequency of emesis, and restriction of eating factor, and the difference was statistically significant (P<0.05).ConclusionsAfter treatment, patients in the experimental group showed a significant increase in BMI, and the frequency of binge eating, frequency of emetic, and restriction of eating factor scores were lower than those of the control group. This suggests that food additives may have potential efficacy in alleviating the symptoms of anorexia nervosa.

BackgroundAcute Respiratory Distress Syndrome (ARDS) is a severe lung disease, and its condition can lead to depressive disorders in patients. Understanding the subjective sleep quality of ARDS patients with depressive disorder conditions and their influencing factors is essential for developing effective interventions and improving patients’ sleep quality.Subjects and MethodsSixty patients with depression were selected as the study subjects and randomly divided into experimental and control groups, with 30 people in each group. Pittsburgh Sleep Quality Index (PSQI), Symptom Checklist-90 (SCL-90), Self-Rating Anxiety Scale (SAS), Social Desirability Scale (SDS), State-Trait Anxiety Inventory (STAI), Life Event Scale (LES), and SQL Server Reporting Services (SSRS) were used for assessment. The data collected were analyzed by the relationship between PSQI and the results of the other six rating scales using SPSS23.0.ResultsSleep disorders were found in 77.8% of 60 patients with depression. The total score and factors of PSQI were significantly correlated with SCL-90 somatization, obsessive-compulsive disorder, depression, anxiety, and total mean score (P<0.05). The PSQI was positively correlated with SAI in SAS and STAI (P<0.01) but not correlated with TAI in STAI (P>0.05). The somatization disorder factor in SDS was significantly correlated with the PSQI factors and total scores except for the sleep persistence factor (P<0.05). The daytime dysfunction factor in PSQI was significantly correlated with the full score of social support (P<0.05), whereas there was no significant correlation between PSQI and LES (P>0.05).ConclusionsDepressive disorders in ARDS patients hurt their subjective sleep quality.

Authors: Liu Wenbo 
Published: October 2023

BackgroundAt present, students’ learning pressure is increasing, and many schools have introduced psychomusical therapy from the perspective of ideological and political courses to relieve students’ mental anxiety.Subjects and Methods
In this study, 100 students with mental anxiety disorder in a high school were selected as research objects and randomly divided into a control group and a study group. The control group was treated with clomipramine only. The study group was treated with ideological and political curriculum visual threshold psychomusic therapy based on clomipramine therapy and the self-rating Anxiety Scale (SAS) was used for comparative analysis. Finally, Minitab was used for statistical analysis.ResultsAfter 3 months of the experiment, the anxiety scale score of middle school students in the control group changed from 65 points to 54 points; The anxiety scale scores of middle school students in the study group changed from 64 to 46. In the study group, the psychological pressure of students before and after the experiment was significantly different (P<0.05). The experimental results show that the combination of ideological and political curriculum visual psychomusical therapy with drug therapy can alleviate students’ mental anxiety.ConclusionsIn this study, the introduction of visual psychomusic in ideological and political courses into drug therapy has a positive impact on student’s mental anxiety caused by study pressure, and can also arouse other schools’ attention to mental health, provide new ideas for the popularization of psychological counselling, and promote the development of student’s mental health.

Authors: Huang Huiping 
Published: October 2023

BackgroundWith the rapid changes in the urban and rural economic structure, the issue of increasing farmers’ income and the income gap between urban and rural residents are continuously expanding. With the rapid changes in both, farmers’ anxiety is becoming increasingly severe. With the advancement of rural land transfer and agricultural modernization, there have been fundamental changes in farmers’ production patterns and lifestyles, which have had a profound impact on their mental health.Subjects and MethodsThis article selects 156 farmers from a village and randomly divides them into an experimental group and a control group, each consisting of 78 farmers. The experimental group conducted psychological health recording tests under the exploration of innovative farmer income models; The control group was engaged in routine income activities without any changes. The experiment used Excel software and SPSS20.0 software to statistically analyze the results.ResultsThe results showed that there was a significant difference in anxiety symptoms between the two groups of farmers after innovating their income (P<0.05). The anxiety symptoms of the experimental group of farmers have significantly improved, and the proportion of people with reduced anxiety symptoms is as high as 90%.ConclusionsTo sum up, the emergence of farmers’ anxiety disorder is related to many factors, such as agricultural production, market contraction, and imperfect rural infrastructure. Innovating farmers’ income models can effectively alleviate the anxiety symptoms of farmers.

Authors: Ying Ying 
Published: October 2023

BackgroundCollege education plays an important role in moral development and values, but some students may face mood disorders. Interventions in educational psychology can help students overcome obstacles and achieve well-rounded development.Subjects and MethodsStudents at one university were selected for the study, and data were collected using questionnaires and tools such as the Stanford Acute Stress Response Questionnaire (SASRQ) and 3-Minute Disorder Assessment Scale (3D-CAM). The experiment focused on students’ moral judgment, behavior, sense of burnout, sense of self-responsibility and emotional state. The data were processed by State statistical software.ResultsThe results show that there are some differences in moral judgment and behavior of the students. Some students show burnout, lack of self-responsibility and emotional instability. Specific data are as follows: The mean score of moral judgment was 3.82 (SD =0.56), the mean score of behavioral performance was 4.05 (SD =0.61), the mean score of burnout was 2.94 (SD =0.72), the mean score of self-responsibility was 3.17 (SD =0.68), and the mean score of emotional state was 2.75 (SD =0.59).ConclusionsThe application of educational psychology in college education can take intervention measures. Developing educational programs and activities aims at character development to enhance moral judgment and behavior. For students with mood disorders, psychological counseling and support are provided to help overcome burnout, enhance the sense of self-responsibility, and adjust emotions. The Stanford Acute Stress Response Questionnaire (SASRQ) and 3-Minute Disorder Assessment Scale (3D-CAM) can assess mood disorders and psychological states and provide a basis for intervention.

Authors: Hu Zhihong 
Published: October 2023

BackgroundAttention deficit hyperactivity disorder (ADHD) is teenagers’ most common mental and behavioral disorder. Students with ADHD often tend to fidget with their hands and feet while attending in-person English classes. This behavior can impede their ability to engage effectively in learning, consequently leading to suboptimal academic outcomes. The online teaching mode is studied to improve the English learning effect of students with hyperactivity disorder.Subjects and MethodsThe study divided 100 ADHD students in a city into an experimental group and a control group, in which 50 ADHD students in the experimental group were taught in English online teaching mode. In comparison, 50 students in the control group received English offline teaching mode. The study used the attention deficit hyperactivity disorder rating scale (SNAP-IV) to measure and finally compared the final scores of the two groups of students from September 2021 to January 2022 with the SNAP-IV score.ResultsThe data were analyzed by SPSS23.0 statistical software. The final English scores of the experimental group and the control group were (80.24±1.24) and (75.31±1.36) respectively, and the SNAP-IV scores of the experimental group and the control group were (12.2±2.7) and (15.1±2.3) respectively. The experimental group was superior to the control group, and there was a significant difference between the two groups (P <0.05).Conclusions
Online English teaching can effectively reduce students’ divergent attention and improve students’ learning concentration.
Optimization of logistics supply chain management model on consumer purchase anxiety disorder
Authors: Li Yufeng 
Published: October 2023

BackgroundAnxiety refers to the intense, excessive, and persistent anxiety and fear in daily life, which will peak in a few minutes. Especially in online shopping, patients with anxiety will aggravate their anxiety because of the slow delivery of the traditional logistics supply chain management model. To reduce consumers’ anxiety, the network distribution system of logistics supply chain management mode is optimized.Subjects and MethodsThis study divided 200 patients with anxiety disorder in a city into a control group and an experimental group. In the experimental group, 100 patients used the optimized logistics supply chain management mode for online shopping. In contrast, in the control group, 100 patients used the traditional logistics supply chain management mode for online shopping. The study also used the self-rating anxiety scale (SAS) for psychological measurement and compared the SAS scores of the two groups of consumers for two months.ResultsThe data were analyzed by SPSS23.0. The SAS score of the experimental group was (1.63±0.23), and that of the control group was (1.81±0.59). The SAS scores of patients in the experimental group were better than those in the control group, and there were apparent differences between the two groups (P < 0.05).ConclusionsResearch on the choice of logistics supply chain management mode for online shopping optimizing its network distribution system can effectively shorten the online shopping distribution time and reduce consumers’ purchase anxiety.
