Effect of Family Cohesion on Depression of Chinese College Students in the COVID-19 Pandemic: Chain Mediation Effect of Perceived Social Support and Intentional Self-Regulation

Individuals’perceptions,attitudes,and patterns of getting along with family members are important factors influencing Chinese people’s self-evaluation.The aim of this study was to investigate the effect of family cohesion on depression and the role of perceived social support and intentional self-regulation in this association.A hypothesized model of the association of family cohesion,perceived social support,intentional self-regulation,and depression was examined.A convenience sampling method was used to survey 1,180 college students in Yunnan Province using self-report.Data were collected using the Family Cohesion Scale,the Perceived Social Support Scale,the Intentional Self-Regulation Scale,and the Center for Epidemiological Studies Depression Scale.The findings revealed low to moderate correlation between the variables studied.College students’family cohesion was a negative predictor of their depression.This association was also mediated by the knock-on effect of perceived social support and intentional self-regulation.These findings show how family cohesion affects college students’depressive status.Specifically,these results help demonstrate the importance of family cohesion,perceived social support,and intentional self-regulation in optimizing students’depression,which in turn can promote better psychological states.

The self-regulation process and its mechanism of channels' bed changes in the Changjiang(Yangtze) Estuary in China

Recent bathymetric changes in the Changjiang Estuary under the influence of artificial regulation engineerings and basin reservoirs have been analyzed based on the maritime charts since 1997 and recent fieldworks. The results indicate a slight erosion of the channels in the upper and middle estuary, continuing deposition and seaward move of the mouth bar crest and intensifying erosion at the nearshore seabed. It is noteworthy that the morphological evolution caused by intensive human activities dominates over the changes from nature process. First, the riverbes are eroded overall in the South Branch （SB）, the South Channel （SC） and the upper and middle reaches of the North Channel （NC）. The nearshore seabed outside the river mouth is being eroded slightly, which is attributed to the declining sediment supply from the Changjiang Basin due to the construction of the Three Gorges Dam upstream. The sediment above the seabed is very active and coarsened, meanwhile, sand waves are becoming more distinct. Second, a deposition occurs in the North Brach （NB）, the mouth of the NC, the mouth bars of the North Passage （NP） and the South Passage （SP） and especially the main channel of the NP, where it shows a massive siltation after the deep waterway project. The reasons for the recent changes are not only the dynamic structure in estuarine mouth bars, but also the supply of sediment resuspension in a local and offshore area. Meanwhile, the severe erosion and siltation in some reaches is related to the construction of estuarine engineerings. It is indicated that the Changjiang Estuary is gradually self-adjusted and adapting to the varying natural factors and intensive human activities. The study on the mechanism of self-regulation of the recent bathymetric changes in the Changjiang Estuary has important and practical significance.

The Survey of Self-Regulation Behaviors and Related Factors in Elderly with Hypertension in South-East of Iran

Hypertension is one of the most important risk factors for heart diseases today. The effect of hypertension in the elderly is higher than other age groups and it may lead to changes in their quality of life. By the increase of age, the amount of self-care behaviors of patients with hypertension decreased. Therefore, control and self-care behaviors are so important. This study has been conducted to study self-regulation behaviors and Associated Factors in elderly patients with hypertension. This study was a cross sectional, descriptive analytic study, which was conducted using multistage sampling on the elderly 60 years and above with hypertension. The sample size was calculated 365 and the final sample size of 380 people was considered by possible losses. The instruments include of demographic and self-regulatory behaviors questionnaire. The results showed that self-regulation of behavior was 42.3% of the total score. In terms of quality, only 7.4% of the elderly had good behavior, 46.6% of poor performance, and the rest were mediocre performance. Age (p = 0.03), gender (p = 0.02), education (p = 0.001), income level (p = 0.03) and marital status (p = 0.001) significantly associated with behaviors of self-regulation. The results generally indicate unfavorable self-regulation of elderly patients with hypertension. Some variables such as gender, age, marital status, education and income levels were associated with these behaviors. So paying attention to the education of the elderly in care centers is essential.

Preparation and Characteristic of Self-regulation Water-transmitting Coating Fiber

Common clay, Kaolin and Bentonite were used as additives to prepare water-transmitting coating fiber, respectively, and the water-transmitting characteristic of coating fiber was studied. Different water-transmitting coating fibers were prepared by coating fiber using coating material with different mass proportions of additives to adhesive. And the coating materials were made from three kinds of inorganic clays as additives respectively and polyvinyl alcohol （PVA） as adhesive. Furthermore, the surface morphology and water-transmitting capacity of coating fiber were studied by SEM, Perkin Elmer Diamond SII thermal multi-analyzer and instrument for quick measurement moisture M30. The experimental results indicate that water-transmitting coating fibers made from three kinds of clays all have water-transmitting capacity. The surface of water-transmitting coating fiber prepared by common clay T is continuous and compact, and the water-transmitting effect is better than coating fibers made from other clays.

Role of Self-Regulation and Self-Care With Academic Performance

Life demands compete with academic study for all levels of education.Higher education now includes strong representation of multiple generations as well as strong representation of both campus-based and online students.Research indicates that students at various stages and in different formats of academic study present some different needs as well as different strategies for managing these needs concurrently with academic study.Research has supported the use of self-care behaviors in reduction of stress,with some studies indicating also an association of self-care and academic performance.In addition,research has also indicated role of student-driven factors such as self-regulation in academic performance.Much of self-care behaviors such as physical activity,consumption of fruits and vegetables,and sleep habits include self-regulation.This study examined association of self-care behaviors in physical activity,consumption of fruits and vegetables,and sleep from selected items of the Personal Wellness Questionnaire and Plan and self-regulation from selected scales of the Motivated Strategies for Learning Questionnaire(MSLQ)of Organization,Resource Management,Effort regulation,and Help-Seeking.Results will assist educators in promotion of student self-care and self-regulation behaviors that can facilitate successful academic endeavor.Answers will also provide guidance to educators and institutions on priority of effort in students support for self-care and self-regulation.

Neuroimaging Phenomenology of the Central Self-Regulation Mechanisms

Functional MRI was used to map the brains of subjects on-line during the process of media training for the acquisition and improvement of self-regulation mechanisms. The temporal and spatial dynamics of the new neural network formation were studied in real and simulated (false) biofeedback game, and their qualitative characteristics were discussed. It has been shown that immersion into a virtual competitive game, controlled by physiological responses, causes a wide involvement of the cortices, characterized by a high volume of activation in the mid-temporal, occipital and frontal areas, the cuneus and the precuneus. In both forms of media training, high values of activation volume were identified in the cerebellar structures.

Exploring the Role of Self-Regulation for College Students

Zimmerman(2000) defines self-regulation as the beliefs and actions which are produced by students themselves in order to achieve their academic success and goals. College students, especially freshmen, are facing a large workload and a relatively flexible learning atmosphere compared with their experience in high school. Self-regulation seems to be an important component in acquiring academic achievement for college students. In other words, students who can control their learning processes effectively are characterized as self-regulated learners(Schunk & Zimmerman 1994). Many people believe that everyone could be self-regulated learner,but what differentiates them most is the quality of their self-regulation( as cited in Cohen 2012). Therefore, understanding the role of self-regulation and how to manage students' learning experiences in order to improve their self-regulation ability are significant.

A Skin-Inspired Self-Adaptive System for Temperature Control During Dynamic Wound Healing

The thermoregulating function of skin that is capable of maintaining body temperature within a thermostatic state is critical.However,patients suffering from skin damage are struggling with the surrounding scene and situational awareness.Here,we report an interactive self-regulation electronic system by mimicking the human thermos-reception system.The skin-inspired self-adaptive system is composed of two highly sensitive thermistors(thermal-response composite materials),and a low-power temperature control unit(Laserinduced graphene array).The biomimetic skin can realize self-adjusting in the range of 35–42℃,which is around physiological temperature.This thermoregulation system also contributed to skin barrier formation and wound healing.Across wound models,the treatment group healed~10%more rapidly compared with the control group,and showed reduced inflammation,thus enhancing skin tissue regeneration.The skin-inspired self-adaptive system holds substantial promise for nextgeneration robotic and medical devices.

Construction of smart propellant with multi-morphologies

Smart materials,which exhibit shape memory behavior in response to external stimuli,have shown great potential for use in biomedical applications.In this study,an energetic composite was fabricated using a UV-assisted DIW 3D printing technique and a shape memory material(SMP)as the binder.This composite has the ability to reduce the impact of external factors and adjust gun propellant combustion behavior.The composition and 3D printing process were delineated,while the internal structure and shape memory performance of the composite material were studied.The energetic SMP composite exhibits an angle of reversal of 18 s at 70°,with a maximum elongation typically reaching up to 280% of the original length and a recovery length of approximately 105%during ten cycles.Additionally,thermal decomposition and combustion behavior were also demonstrated for the energetic SMP composite.

Research on the Legal Framework of Content Regulations for Network Platforms

In the era of the Internet,various network platforms have evolved into new hubs for information dissemination.Currently,China has established a platform-centered content regulation framework,wherein platforms proactively enforce content regulations in accordance with legal censorship obligations.Additionally,platform policies and user agreements augment their authority in content regulation.The platforms can achieve cost-effective and highly efficient content regulation by leveraging their strategic advantages enabled by their own technical capabilities and extensive coverage.The platform self-regulation model,however,still faces challenges.First,accurately evaluating content remains a formidable task;second,ensuring effective platform publicity through self-regulation poses difficulties;third,users may potentially face disadvantages due to the platform’s right of self-regulation;and fourth,digital copyright owners face challenges when defending digital copyright disputes under the safe harbor rule.Therefore,it is imperative to establish,review,and revise the legal framework for content regulation of network platforms in order to enhance the efficiency of their governance systems.The formulation of the legal framework for content regulation of network platforms may encompass the following aspects:rationalizing obligations pertaining to platform content regulations,enhancing supervision over platform self-regulation,and establishing a dual-track responsibility system for digital copyright content regulation.This will ensure a harmonious balance among public interests,users’personal rights and interests,and commercial benefits through regulating the content on network platforms.

Understanding the effects of structured self-assessment in directed,self-regulated simulation-based training of mastoidectomy:A mixed methods study

Objective:Self-directed training represents a challenge in simulation-based training as low cognitive effort can occur when learners overrate their own level of performance.This study aims to explore the mechanisms underlying the positive effects of a structured self-assessment intervention during simulation-based training of mastoidectomy.Methods:A prospective,educational cohort study of a novice training program consisting of directed,self-regulated learning with distributed practice(5x3 procedures)in a virtual reality temporal bone simulator.The intervention consisted of structured self-assessment after each procedure using a rating form supported by small videos.Semi-structured telephone interviews upon completion of training were conducted with 13 out of 15 participants.Interviews were analysed using directed content analysis and triangulated with quantitative data on secondary task reaction time for cognitive load estimation and participants’self-assessment scores.Results:Six major themes were identified in the interviews:goal-directed behaviour,use of learning supports for scaffolding of the training,cognitive engagement,motivation from self-assessment,selfassessment bias,and feedback on self-assessment(validation).Participants seemed to self-regulate their learning by forming individual sub-goals and strategies within the overall goal of the procedure.They scaffolded their learning through the available learning supports.Finally,structured self-assessment was reported to increase the participants’cognitive engagement,which was further supported by a quantitative increase in cognitive load.Conclusions:Structured self-assessment in simulation-based surgical training of mastoidectomy seems to promote cognitive engagement and motivation in the learning task and to facilitate self-regulated learning.

Self-regulating Humidity Activated Carbon Material Prepared from Bamboo for the Room

A self-regulating humidity material with bamboo for the room was prepared. The activated carbons were prepared with the temperature rising rates of 5, 10, 15, 20 ℃/min and constant temperatures of 600, 700, 800, 900, 1 000, 1 100, 1 200, 1 300, 1 400, and 1 500 ℃ for 0.5, 1, 2, 3, and 6 h, respectively.And then their structures such as specific surface areas, volumes of pores from 3.7-7.1 nm and average pore diameters were tested. Various humidity conditions were simulated and their self-regulating humidity properties such as absorption/desorption contents, rates and stabilities were evaluated. The results show that the specific surface area, volume of pores from 3.7-7.1 nm and average pore diameter of activated carbon are closely nonlinearly related to the temperature rising rate, temperature and holding time. In general, the activated carbon prepared with the temperature rising rate of 5 ℃/min and kept at 1 100 ℃ for 2 h has the highest absorption/desorption content and rate, the lowest decay factor and then the best stability at all humidity for the fact that it is provided with proper average pore diameter, higher specific surface area and volume of pores from 3.7-7.1 nm. The activated carbons can be prepared with the temperature rising rate of 5 ℃/min and kept at 1000, 900,1 200, 1 300, 1 400, 1 500, 800, 700, and 600 ℃ respectively for 2 h. These resulted properties are attributed to their different average pore diameters and volumes of pores from 3.7-7.1 nm.

Assembling structurally customizable synthetic carriers of si RNA through thermodynamically self-regulated process

This study demonstrates that our previously reported polywraplex, a synthetic siRNA carrier consisting of a uni-molecular polyplex core of customizable size and a self-assembled triblock copolymer envelop, may be constructed using dendrimers as the crosslinking junctions. Replacing the branched low molecular weight PEI with polyamidoamine(PAMAM) dendrimer in the zeta potential regulated polymerization resulted in the similar network structured cationic polymer with electron microscopically visible crosslinking junctions. This visibility may offer a convenient way to characterize the molecular structure of the rationally designed networked siRNA-packing cationic polymer without altering its chemical properties and biologic functions. A series of physical-chemical characterizations and biological assays, comprising size, zeta potential, pre-phagocytic siRNA leaking and degradation, and silencing of functional genes, confirmed that the advanced properties of polywraplexes remained with the dendrimer junctions. Although sixth generation PAMAM dendrimer was used as the crosslinking junctions in the size-customizable polymerization for electron microscopic observation, lower generation dendrimer should also work in case more practical and structurally defined cationic polymer is needed.

当代认知生成主义的理论研究进路及其哲学反思

认知生成主义的产生有其认知科学的学科资源和现象学哲学基础。认知生成主义在挑战、批判并超越传统认知科学研究范式的基础上,目前已经至少发展出了三条理论研究进路:自创生的生成主义、感觉运动的生成主义和激进的生成主义。这三条并存的理论研究进路对认知生成主义研究的侧重点和结论各有不同,表明了当代认知生成主义研究呈现出复杂的“争鸣”现象。这些理论研究进路具有重要的哲学本体论、认识论和方法论意义,但也暴露出一定的模糊性、争议性和不彻底性。因此,我们需要对它们进行哲学反思,这对于揭示当代认知生成主义这一研究纲领的复杂性和对未来生成认知科学的发展具有重要的启示意义。

The body can heal itself in trauma:concept and practical exercises

Post-traumatic stress disorder is caused by a traumatic experience,for example rape,a natural disaster,war,serious accidents.Memories of the trauma often haunt the affected person in everyday life.Anyone who has to survive one or more such extreme situations can suffer from post-traumatic stress disorder,even witnesses of a traumatic event[1].If the disorder is not treated,it can become chronic and massively limit the quality of life.With timely and correct therapy,the chances of recovery are good.In the experience and psychological processing of those affected,there is a difference whether this catastrophe was a natural disaster or a“man made disaster”in a war or post-war area.It becomes very difficult when the two come together,as for example in Banda Aceh in 2004.The associated individual experience of fear of death,panic,helplessness,loss of control and powerlessness is the same for both types of disaster at the moment it happens.However,the processing of the traumatising experience is different.Traumas caused by people are more difficult for the individual to process than natural disasters.The article describes in detail what happens in the body and in the person during traumatisation.It also describes how the body can heal itself.The second part of the article presents the concrete exercise programme for practice.
