Deep Learning Social Network Access Control Model Based on User Preferences

A deep learning access controlmodel based on user preferences is proposed to address the issue of personal privacy leakage in social networks.Firstly,socialusers andsocialdata entities are extractedfromthe social networkandused to construct homogeneous and heterogeneous graphs.Secondly,a graph neural networkmodel is designed based on user daily social behavior and daily social data to simulate the dissemination and changes of user social preferences and user personal preferences in the social network.Then,high-order neighbor nodes,hidden neighbor nodes,displayed neighbor nodes,and social data nodes are used to update user nodes to expand the depth and breadth of user preferences.Finally,a multi-layer attention network is used to classify user nodes in the homogeneous graph into two classes:allow access and deny access.The fine-grained access control problem in social networks is transformed into a node classification problem in a graph neural network.The model is validated using a dataset and compared with other methods without losing generality.The model improved accuracy by 2.18%compared to the baseline method GraphSAGE,and improved F1 score by 1.45%compared to the baseline method,verifying the effectiveness of the model.

Investigating the Cognitive Control of Social Media-Anxious Users Using a Psychological Experimental Approach

Social media has become increasingly popular and is now a significant tool for daily communication for many people.The use of social media can cause anxiety and have detrimental impacts on mental health.Cognitive impairment is more likely to affect individuals with anxiety.Investigating the cognitive abilities and mental health of social media users requires the development of new methodologies.This study employed the AX-Continuous Performance Test(AX-CPT)paradigm and the Stroop paradigm to study the cognitive control characteristics of trait anxiety,drawing on psychological experimental methods.Previous studies on whether trait anxiety impairs cognitive control remain controversial,possibly because cognitive control is viewed as a whole.It may also be due to the motivational effect of anxiety,which compensates for the impairment of cognitive control caused by anxiety through the recruitment of cognitive resources.Understanding the mental health and cognitive control traits of anxious social media users can be improved by using the Dual Mechanisms of Cognitive Control Account,which divides cognitive control into proactive and reactive control.Thefindings demonstrate that trait anxiety has an impact on both proactive and reactive control,while working memory load did not modulate the effect of trait anxiety on cognitive control.These results support the attentional control theory and provide a new approach to studying the mental health of social media users.

Relationship between acute stress and sleep disorder in grass-root military personnel:Mediating effect of social support

Background: To explore the relationship between acute stress, social support and sleep disorder in grass-root military personnel, and construct the relational model through structural equation modeling. Methods: A total of 2,411 grass-root military personnel were randomly selected by cluster sampling, and administered the Chinese Military Personnel Sleep Disorder Scale, Military Acute Stress Scale and Social Support Rating Scale.Results: The total score of acute stress scale was positively correlated with the total score and factor scores of sleep disorder scale(r=0.209~0.465, P<0.01); The total score of social support scale was positively correlated with the total score of acute stress scale and the total score and factor scores of sleep disorder scale(r=0.356~0.537, P<0.01). The analysis of mediating effects showed that lack of social support partially mediated between acute stress and the factors of sleep disorder. The analysis of structural equation model showed that acute stress not only had a direct effect on sleep disorder(the path coefficient was 0.29, P=0.000), but also on lack of social support(the path coefficient was 0.39, P=0.000); lack of social support had a direct effect on sleep disorder(the path coefficient was 0.48, P=0.000).Conclusions: Acute stress and lack of social support are two significant factors of sleep disorder in grass-root military personnel. Well-established social support could alleviate sleep disorder induced by acute stress. Lack of social support was a partial mediator between acute stress and sleep disorder.

Multiple mediation effects of health locusof control and hope on the relationshipbetween stroke patients’ social supportand self-management

Objective:This study aimed to identify the mediation effects of health locus of control(HLC)and hope between stroke patients’social support and self-management.Methods:A cross-sectional study was conducted.A total of 300 Chinese stroke patients were recruited by convenient sampling from the acupuncture department of two Chinese Traditional Medical Hospitals in Tianjin Province from June to September 2018.The self-report questionnaires include Social Support Assessment Scale,Herth Hope Index,Mental Health Locus of Control Scale,Stroke Self-management Behavior Scale,and personal information questionnaires.All the survey data were entered in Excel and analyzed using the SPSS 24.0 program.Mediation was tested with Bootstrapping in AMOS 23.0 program.Results:The result showed that internal health locus of control(IHLC),chance health locus of control(CHLC)and hope were the mediators between social support and self-management.The direct,indirect,and total effects of social support on self-management behavior were 0.306 (P<0.01),0.109(P<0.01),and 0.415(P<0.01),respectively.Conclusions:Social support can directly influence self-management,and it can also indirectly influence self-management through IHLC,CHLC,and hope.

The Research on Social Networks Public Opinion Propagation Influence Models and Its Controllability

Public opinion propagation control is one of the hot topics in contemporary social network research. With the rapid dissemination of information over the Internet, the traditional isolation and vaccination strategies can no longer achieve satisfactory results. A positive guidance technology for public opinion diffusion is urgently needed. First, based on the analysis of influence network controllability and public opinion diffusion, a positive guidance technology is proposed and a new model that supports external control is established. Second, in combination with the influence network, a public opinion propagation influence network model is designed and a public opinion control point selection algorithm(POCDNSA) is proposed. Finally, An experiment verified that this algorithm can lead to users receiving the correct guidance quickly and accurately, reducing the impact of false public opinion information; the effect of CELF is no better than that of the POCDNSA algorithm. The main reason is that the former is completely based on the diffusion cascade information contained in the training data, but does not consider the specific situation of the network structure and the diffusion of public opinion information in the closed set. thus, the effectiveness and feasibility of the algorithm is proven. The findings of this article therefore provide useful insights for the implementation of public opinion control.

Environmental and Psycho-social Factors Related to Prostate Cancer Risk in the Chinese Population:a Case-control Study

Objective To study the risk environmental and psycho-social factors associated to prostate cancer （PCa） in Chinese population. Methods 250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios （OR） and 95% confidence intervals （95% CI） for relationship between lifestyle, eating habits and psycho-social factors with PCa risk. Results Green vegetables and green tea were associated with a decreased risk of PCa （0R=0.39, 95% CI： 0.28-0.53; 0R=0.59, 95% Cl： 0.40-0.87, respectively）. Family history of PCa （0R=7.16, 95% CI： 2.01-25.49）, history of prostate diseases （0R=2.28, 95% Cl： 1.53-3.41）, alcohol consumption （0R=1.97, 95% CI： 1.33-2.90）, red meat consumption （0R=1.74, 95% CI： 1.20-2.52）, barbecued （0R=2.29, 95% CI： 1.11-4.73） or fried （0R=2.35, 95% CI： 1.24-4.43） foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks （0R=1.61, 95% CI： 2.00-2.59）, marital separation （0R=1.94, 95% CI： 1.29-2.91）, self-contained suffering {0R=2.37, 95% CI： 1.58-3.55）, and high sensitivity to the personal comments （0R=1.73, 95% CI： 1.18-2.54） were related to PCa. Conclusion Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population.

Memory Suggestibility under Social Pressure and Inhibitory Control in Preschoolers

The current study examined the interaction of inhibitory control and social pressure on young children’s memory suggestibility. Children were administered the Video Memory Suggestibility Scale for Children (VMSSC) and batteries of inhibitory control tasks, and were exposed to different levels of situational social pressures during interviews for memory suggestibility. The findings indicated that inhibitory control played a significantly moderating role in the relationship between social pressure and memory suggestibility. The greater the inhibitory control, the lower the effects of social pressure on the memory suggestibility of children. For the children with lower levels of inhibitory control, the social pressure positively predicted memory suggestibility;but for the children with higher levels of inhibitory control, the social pressure didn’t significantly predict memory suggestibility. So, to a certain extent, memory suggestibility may be a dynamic integration of stable trait and fluctuating state elements. The implications for the essence of memory suggestibility were discussed.

Can Social Support and Control Agency Change Illness Consequences? Evidence from Cervix Cancer Patients

Research has demonstrated facilitative effects of social support on psychological and physical well-being of individuals suffering from chronic health problems. Social support can change not only patients’ perception of their health problems, but also the consequences of their illness. In the present study with cervix cancer patients, the relationship of social support and illness control agency with illness consequences and health outcome beliefs was examined. Emotional, informational, social companionship and practical supports were found to be negatively correlated with the severity of interpersonal, physiological and psychological consequences of illness. Patients’ belief in self-control and doctor-control was related to less severity and less pain of illness, and strong hope for better health outcomes.

Effects of combination pharmacotherapy and social skills training for schizophrenia: A randomized controlled trial

Pharmaco-psychosocial treatment (PPST) refers to a treatment paradigm combining pharmacotherapy with psychosocial therapy. We conducted an 18-month randomized controlled tracking study to evaluate the efficacy of social skills training (SST) in 11 individuals with schizophrenia on risperidone monotherapy. They were randomized to either SST or non-SST group, and Global Assessment Functioning (GAF) and Brief Psychiatric Rating Scale (BPRS) scores in the 2 groups showed gradual improvement. In the SST group, Digit Span Distraction Test (DSDT) at 12 and 18 months showed significant improvement. The Subjective Deficit Syndrome Scale (SDSS) scores in the SST group showed significant improvement after 6 months and showed a significant difference in comparison between the groups. After the subjective feeling of health was recovered, the items of motivation were recovered as a direct effect of SST. Some items of the Life Assessment Scale for the Mentally Ill (LASMI) score showed significant improvement (or significant trend) in only the SST group after 6 months. Items of daily life, work skills, and self-recognition were continuously improved. We report 2 cases in the SST group that had DSDT improvement in parallel with change of action and communication as a change of social function. This study is only exploratory due to the small number of cases. However, we have demonstrated potential improvement in cognitive function due to learning experiences that required working memory and attention, thus providing improvement in social life.

CRSG:A congestion control routing algorithm for security defense based on social psychology and game theory in DTN

The inherent selfishness of each node for the enhancement of message successful delivery ratio and the network overall performance improvement are reflected in the contradiction relationship of competition and cooperation in delay/disruption tolerant networks (DTN). In particular, the existence of malicious node aggravates this contradiction. To resolve this contradiction, social relationship theory and group theory of social psychology were adopted to do an in-depth analysis. The concrete balancing approach which leveraged Nash equilibrium theory of game theory was proposed to resolve this contradiction in reality. Thus, a new congestion control routing algorithm for security defense based on social psychology and game theory (CRSG) was put forward. Through the experiment, this algorithm proves that it can enhance the message successful delivery ratio by more than 15% and reduce the congestion ratio over 15% as well. This algorithm balances the contradiction relationship between the two key performance targets and made all nodes exhibit strong cooperation relationship in DTN.

困境与破解:强制报告制度的法社会学分析——以家庭暴力侵害未成年人案件为视角

法律与社会发展不可分离。未成年人保护不仅是一个法律问题,更是一个社会问题。法律虽为社会控制的高级手段,亦不可脱离社会独自发挥作用,需与道德规范、社会价值观、文化等其他社会控制手段互为表里。从法社会学的研究视角出发,家庭暴力侵害未成年人案件强制报告制度具有多种实践价值,但该制度在一定程度上冲击了部分报告义务主体和社会公众的固有思想观念,致使部分报告义务主体履行强制报告义务缺乏精神动力,阻碍了该制度在实践中的顺利运行。应从回应社会发展需求、关注特殊群体权益保障、加强社会控制、培育和塑造现代公民等方面,借助其他社会控制手段化解思想观念冲突,破解强制报告制度的适用困境,进一步提高强制报告制度在家庭暴力侵害未成年人案件中的适用实效。

控制论视域下高校师生廉洁知行与腐败自我控制实证研究——以高校师生廉洁知行抽样调查为例

赫希的自我控制理论认为,个体的低自我控制是其实施犯罪或类犯罪行为的原因,社会纽带薄弱则低自我控制,依恋、奉献、参与、信念是反映社会纽带强弱的因素,也是考察个体自我控制高低的因变量。为考察高校师生反腐社会纽带和腐败自我控制,笔者对五地域高校师生廉洁知行现状进行了抽样问卷调查,根据回收的调查问卷,分析高校师生廉洁认知、廉洁知行统一性,研究高校师生反腐社会纽带、腐败自我控制现状。实证研究发现,大部分高校师生反腐社会纽带较强,腐败自我控制较高,但部分高校师生存在廉洁认知模糊、廉洁知行不统一等问题,反腐社会纽带薄弱、腐败自我控制较低,个体腐败风险大。以社会纽带理论和自我控制理论为启示,探索增强高校师生反腐社会纽带、提升腐败自我控制路径,预防师生腐败犯罪及类腐败行为。
