Brain Research on Mental Disorders: A Criticism

Objective: To expose the problems and inherent limitations of neuroscience-based brain research on mental disorders. Method: Discussion of the theory underlying brain research on mental disorders, followed by a systematic evaluation of typical studies. Results: The fundamental problem is that brain researchers fail to differentiate between biological mental disorders in which brain processes cause the disorder (notably schizophrenia, bipolar disorder, and melancholic depression) and learned mental disorders in which brain processes mediate but do not cause the disorder (which is the case with reactive depression, reactive anxiety, OCD, and PTSD). Researchers have been unsuccessful in identifying mechanisms in the brain that cause biological mental disorders, and will never be able to locate the innumerable specific neural connections that mediate learned mental disorders. Moreover, the author’s review of typical studies in this field shows that they have serious problems with theory, measurement, and data analysis, and that their findings cannot be trusted. Conclusions: Neuroscience-based brain research on mental disorders, unlike other neurological research, has been an expensive failure and it is not worth continuing.

An Experimental Study on the Effectiveness of Individualized Online Intervention for Mental Health Literacy of Community Residents

Background:Understanding how to improve mental health literacy is conducive to maintaining and promoting individuals’mental health and well-being.However,to date,interventions for mental health literacy primarily depend on traditional education and contact interventions,which have limitations with regard to pertinence and individualization.Artificial intelligence(AI)and big data technology have influenced mental health services to be more intellectual and digital,and they also provide greater technical convenience for individualized interventions for promoting mental health literacy.However,there is relatively little research on the effectiveness of individualized online intervention for mental health literacy in the literature.This study aims to fill this void.To verify whether individualized online intervention can improve the level of mental health literacy.Methods:We conducted a pretest–post-test control experiment.The participants were recruited from a large community located in central China.A total of 152 participants completed the research.We use mixed linear model estimation and paired t-tests to analyze the data.Results:Individualized online intervention can effectively improve the mental health literacy level of participants.Specifically,we found that compared with the control group,the mental health literacy in the experimental group was significantly improved after receiving individualized online intervention.Likewise,the mental health literacy of the control group has also improved after receiving individualized online intervention.In addition,we compared the mental health literacy level of the experimental group at Time 3 to those at Time 2 and found that the mental health literacy level at Time 3 had not decreased one month later.This shows that individualized online intervention was not only momentarily effective,but also had long-term efficacy.Conclusion:This study illustrates that the individualized online intervention has both great momentary and long-term effectiveness in improving community residents’mental health literacy.

Towards Innovative Research Approaches to Investigating the Role of Emotional Variables in Promoting Language Teachers’ and Learners’ Mental Health

The adequacy of language education largely depends on the favorable and unfavorable emotions that teachers and students experience throughout the education process.Simply said,emotional factors play a key role in improving the quality of language teaching and learning.Furthermore,these emotional factors also promote the well-being of language teachers and learners and place them in a suitable mental condition.In view of the favorable impact of emotional factors on the mental health of language teachers and learners,many educational scholars around the world have studied these factors,their background,and their pedagogical consequences.Nonetheless,the majority of previous studies have employed traditional research methods in assessing these variables and their influences on language teachers’and learners’mental health.Because of the complex and dynamic quality of emotional factors,traditional research approaches often fail to evaluate these factors and their dynamic,non-linear connections with teachers’and learners’mental health and well-being.Accordingly,some novel research approaches are required to measure the dynamicity and complexity of emotional factors in language education settings.To address this call,the current state-of-the-art conceptual article seeks to provide new insights for investigating emotional factors and their potential impact on language teachers’and learners’mental states.This study also intends to offer a comprehensive list of emerging methods that take into account the complex and dynamic nature of emotional variables.Finally,the study outlines the potential implications of this review for educational researchers.

Do Research Incentives Promote Researchers’Mental Health?

Background:Researchers have a higher risk of anxiety and depression than the general population,so it is important to promote researchers’mental health.Method:Based on the data from 3210 global researchers surveyed by the journal Nature in 2021,confirmatory factor analysis,OLS regression and other regressions were used to explore the research incentive dimensions and their effects on researchers’mental health.Results:(1)Material incentive factors,work-family life balance factors,good organizational environment and spiritual motivation had significant positive effects on researchers’mental health.(2)The spiritual motivation could better promote researchers’mental health than the other factors.(3)Heterogeneity analysis showed that material incentive factors and spiritual motivation created more significant stimulating effects on the mental health of humanities and social sciences researchers.Work-family life balance factors were more effective in promoting the mental health of the mid-career group and the overtime group.Conclusion:Application of the four research incentives resulted in lower likelihood of anxiety or depression among researchers,and special attention should be paid to the role of the spiritual motivation.In order to promote researchers’mental health,different incentives should be applied to different researcher groups to better improve researchers’mental health.

Experimental and numerical studies of Ca(OH)_(2)/CaO dehydration process in a fixed-bed reactor for thermochemical energy storage

The Ca(OH)_(2)/CaO thermochemical energy storage(TCES)system based on calcium looping has received extensive attention owing to its high energy storage density,prolonged energy storage time,and environmental friendliness.The heat storage process of the Ca(OH)_(2)/CaO TCES system in a mixed heating reactor was evaluated in this study,by employing a combination of direct and indirect heating modes.The dehydration process was studied experimentally,and a numerical model was established and verified based on the experimental results.The dehydration behavior of 500 g of Ca(OH)_(2) powder was investigated in a fixed-bed reactor with mixed heating.The experimental and simulation results indicated that mixed heating causes combined centripetal and horizontal propulsion.Heat input is the main limiting factor in the heat storage process,because the radial advance of the reaction is hindered by the low thermal conductivity of the solid reactant particles.Heat transmission partitions were added to enhance the performance of the reactor.The performance of the modified reactor was compared with that of a conventional reactor.The radial heat transmission partitions in the modified reactor effectively enhance the energy storage rate and reduce the reaction time by 59.5%compared with the reactor without partitions.

The Relationship of Occupational Health Nurses’ Experiences with Associated Departments in Relation to Project Development of Mental Health Care for Primary Preventive Treatment

Purpose: The purpose of this study was to clarify the relationship and experiences of occupational health nurses (OHNs) and related departments in project development of mental health care for primary treatment in the Japanese occupational health setting. Method: A total of 235 OHNs who are members of the Japan Academy of Occupational Health Nursing were sent an anonymous self-administered questionnaire survey. The questionnaire included items on the following: the OHN’s background, whether the OHN had experience in project development, the communication between the associated departments, the Japanese version of the Work Engagement Scale (UWES-J), occupational assessments, workplace assessments, and the Transtheoretical Model (TTM) for health promotion in companies and the OHN’s working environment. We performed logistic regression analysis to examine the relationship between experience and these harmonious relationships with other associated departments. Result: Responses from 61 OHNs (valid response rate: 25.9%) were analyzed. The mean number of years of service as an OHN was 18.9, and 82% of respondents had experience in project development. The logistic analysis further revealed that OHNs who had experience in project development of mental health care usually had a harmonious relationship with other associated departments. Conclusion: To promote mental health care for workers, OHNs have the capability to create individual and workplace assessments, enhance their work engagement, and make further improvements to their working environment. .

Development of plasma sources for Dipole Research EXperiment(DREX)

Dipole Research EXperiment（DREX） is a new terrella device as part of the Space Plasma Environment Research Facility（SPERF） for laboratory studies of space physics relevant to the inner magnetospheric plasmas. Adequate plasma sources are very important for DREX to achieve its scientific goals. According to different research requirements, there are two density regimes for DREX. The low density regime will be achieved by an electron cyclotron resonance（ECR） system for the ‘whistler/chorus＇ wave investigation, while the high density regime will be achieved by biased cold cathode discharge for the desired ‘Alfvén＇ wave study. The parameters of ‘whistler/chorus＇ waves and ‘Alfvén＇ waves are determined by the scaling law between space and laboratory plasmas in the current device. In this paper, the initial design of these two plasma sources for DREX is described. Focus is placed on the chosen frequency and operation mode of the ECR system which will produce relatively low density ‘artificial radiation belt＇ plasmas and the seed electrons, followed by the design of biased cold cathode discharge to generate plasma with high density.

Excitation of chorus-like waves by temperature anisotropy in dipole research experiment (DREX): A numerical study

Due to their significant roles in the radiation belts dynamics, chorus waves are widely investigaled in observations, experiments, and simulations. In this paper, numerical studies for the generation of chorus-like waves in a launching device, dipole research experiment （DREX）, are carried out by a hybrid code. The DREX plasma is generated b} electron cyclotron resonance （ECR）, which leads to an intrinsic temperature anisotropy of energetic electrons. Thus the whistler instability can be excited in the device. We then investigate the effects of three parameters, i.e., the cold plasma density no, the hot plasma density nh, and the parallel thermal velocity of energetic electrons, on the generation of chorus-like waves under the DREX design parameters. It is obtained that a larger temperature anisotropy is needed to excite chorus-like waves with a high nc with other parameters fixed. Then we fix the plasma density and parallel thermal velocity, while varying the hot plasma density. It is found that with the increase of nh, the spectrum of the generated waves changes from no chorus elements, to that with several chorus elements, and then further to broad-band hiss-like waves. Besides, different structures of chorus- like waves, such as rising-tone and/or falling-tone structures, can be generated at different parallel thermal velocities in the DREX parameter range.

Calculating buoy response for a wave energy converter-A comparison of two computational methods and experimental results

When designing a wave power plant, reliable and fast simulation tools are required. Computational fluid dynamics （CFD） software provides high accuracy but with a very high computational cost, and in operational, moderate sea states, linear potential flow theories may be sufficient to model the hydrodynamics. In this paper, a model is built in COMSOL Multiphysics to solve for the hydrodynamic parameters of a point-absorbing wave energy device. The results are compared with a linear model where the hydrodynamical parameters are computed using WAMIT, and to experimental results from the Lysekil research site. The agreement with experimental data is good for both numerical models.

Experiences of rejection by mental health patients— A qualitative study

Background and aim: People suffering from mental illness and their experiences of attitudes towards them are rarely investigated from the perspective of the individual. The aim was to gain an understanding of how a group of mental health patients experienced social relationships in personal settings as well as in society. Method: Open interviews with twenty-five mental health patients were conducted and analysed with a qualitative content analysis. Result: The essence of the result was that mental health patients’ experiences are still not taken enough into account, neither by mental health professionals nor by their social networks. This was underpinned by four core categories: Patients’ experience of deteriorated and reduced social contacts due to various degrees of acceptance and knowledge of people in general;service users reported on difficulties with social contacts in general, with family relationships, relationships with friends and workmates and with employers;reduced life opportunities were expressed, including violated self-image and poor coping competence and, ambivalent experiences of contact with the mental health services were reported. Conclusion and clinical implication: The present study contributes to the understanding of mental health patients’ experiences of professional services and of their social networks. This knowledge may strengthen the implications of patient-centred care essential for the outcome of the care.
