We found that the study group exhibited significantly decreased State-Trait Anxiety Inventory（STAI X-1,X-2） STAX2 scores and Trait Coping Style Questionnaire（TCSQ） negative scores,and increased Interpersonal Support Evaluation List（ISEL） tangible scores from baseline to 9 weeks later（P 〈0.01）. In addition,a between-group difference in changes of TCSQ negative score was observed at the end of week 9（P 〈0.05）. These fi ndings suggest that WLST can improve trait anxiety,coping style,and interpersonal support in male Chinese juvenile violent offenders.展开更多

Aims: To assess the prevalence and pattern of psychiatric disorders among a sample of the violent offenders and to examine any relationship between psychiatric disorders and crimes. Method: This was a two-phase cross-sectional study in three police stations in Ile-Ife/Modakeke area of Nigeria. In the first phase, we screened 400 consecutive adults arrested for violent crimes using the General Health Questionnaire—30. In the second phase, all 36 persons with probable psychopathology were then interviewed with the Present State Examination to make a definitive diagnosis. Results: The mean age of all the subjects was 29.9 years (SD ± 7.3). The male to female ratio was 11:1. Respondents were mostly single (54%);most had secondary education or less (82%) and about 60% were currently using psychoactive substances (drugs). About 8.5% of all the subjects had a diagnosable psychiatric disorder;paranoid schizophrenia was the commonest psychiatric disorder (41.2%). Mentally ill subjects were three times more likely to commit homicidal offence than non-mentally ill subjects. Conclusion: There exists a significant but weak relationship between mental illness and violent crimes.展开更多

However, these agendas fail to deliver their promises in not providing empirical evidences to confirm theory. In this sense, the present paper provides a fresh look to water scarcity implications, presenting a theoretical framework and new causal mechanism based on complex interdependence theory applied to the physical reality in an international basin. As such, the inferred causal mechanism, its parts and causal direction is investigated applying process-tracing technique to the Rio Grande-Colorado River. The paper finds by tracing the causal mechanism evidences to confirm new theory and enough analytical power to test in other cases to increase confidence in theory to fulfill generalization requirement.展开更多

In the meantime, adolescents and especially girls are more likely to be harmed. The purpose of this study was to evaluate the effect of group training with non-violent communication (NVC) method on suicidal ideations and coping with stress styles of adolescent girls. The target community in this research was availably selected from the charity centers of Tehran suburbs. In this study, 15 adolescent girls were in the experimental group and 15 in the control group. The criteria for entering the research were students aged 11 to 19 years and the vulnerable socio-economic income. Eight training sessions of NVC were presented for the experimental group in the pre-test and post-test intervals, while no intervention was performed for the control group. Data collection instruments were Beck’s scale for suicidal ideation (BDI) and Endler & Parker’s coping inventory for stressful situations (CISS). After statistical analysis, the effectiveness of this training was investigated on dependent variables by multivariate analysis of covariance. Eventually, the results showed a significant difference between the experimental and control groups (p < 0.05). The finding of the study showed that NVC training can reduce suicidal ideations in adolescent girls who are socially and economically vulnerable. According to the findings, non-violent communication training has a higher effect on emotion-focused coping style compared to other stress coping styles.展开更多

This study mainly tested the effects of violent stimuli on aggression by employing modified Stroop task. A total of 188 undergraduates participated in this study. Results showed that undergraduates exposing to violent stimuli exhibited high levels of aggression, whereas undergraduates who exposed to non-violent stimuli displayed low levels of aggression. Specifically, males, but not females, manifested high levels of aggression after exposure to violent stimuli. Moreover, viewers with high-aggressiveness (HA), but not with moderate-aggressiveness (MA) and low-aggressiveness (LA), showed high levels of aggression after exposure to violent stimuli via internet.展开更多

This study employed geospatial technologies to integrate spatio-temporal crime, social media and field observation data from the communities in all the six states in the southwest to develop crime hotspots that can serve as preliminary information to assist in allocating resources for crime control and prevention. Historical crime data from January 1972 to April, 2021 were compiled and updated with rigorous field survey in September, 2021. The field data were encoded, input to the SPSS 17 and analyzed using descriptive statistics and multivariate analysis. A total 936 crime locations data were geolocated and exported to ArcGIS 10.5 for spatial mapping using point map operation and further imported to e-Spatial web-based and QGIS for the generation of hotspot map using heatmap tool. The results revealed that armed robbery, assassination and cultism were more pronounced in Lagos and Ogun States. Similarly, high incidences of farmers/herdsmen conflicts are observed in Oyo and Osun States. Increasing incidences of kidnapping are common in all the south-western states but very prominent in Ondo, Lagos and Oyo States. Most of the violent crime incidents took place along the highways, with forests being their hideouts. Violent crimes are dominantly caused by high rate of unemployment while farmer/herdsmen conflicts were majorly triggered by the scarcity of grazing fields and destruction of arable crops. The conflicts have resulted in the increasing cases of rape and disruption of social group, intake of hard drugs, cult-related activities, low income and revenue generation, and displacement of farmers and infrastructural damages. The study advocates regular retraining and equipping of security agents, establishment of cattle ranch, and installation of sophisticated IP Camera at the crime hotspots to assist in real-time crime monitoring and management.展开更多

Strengthening human rights protection requires reinforcing the momentum to crack down and prevent the violent acts of extremist forces. As one of the countries that is the victim of violence by extremists, China has taken a series of measures to tackle the challenges of violent extremism. As President Xi Jinping has pointed out, 'the realization of the full enjoyment of human rights by human beings is the common goal of human society.' While establishing a community of common destiny for all mankind, the international community should take action to effectively address the root causes of violent extremism, maintain a peaceful and secure development environment, and defend the basic human rights and well-being of all peoples, so as to ensure a safe and brighter future for all.展开更多

The disinfectants and insecticides, including HCH (hexachlorocyclohexane) and DDT (dichlorodiphenyltrichoroethane) as representative OCPs, could lead to serious environmental problems. In order to disclose the residues of HCH and DDT in soils following the Wenchuan 5.12 Violent Earthquake, surface soils in Dujiangyan City and Beichuan County were sampled in 2009. The samples were analyzed by GC/MS after pre- treatment by ultrasonic solvent extraction. It has been found that the concentra-tions of γ-HCH, β-HCH and 4,4'-DDT in soils of Beichuan County were 94–102.4, 14.1–36.1 and 2.9–4.3 times high their concentrations in those of the Wolong Nature Reserve, and the concentrations in soils of Dujiangyan City were 52.4–61.6, 8.8 –45.3 and 5.4–6.2 times high their concentrations in soils of the Wolong Nature Reserve, respectively. According to the isomers of HCHs and metabolites of DDTs, it could be concluded that these areas may have additional inputs of lindane and 4,4'-DDT.展开更多

文摘A large number of disinfectants and insecticides were used on a large scale after the Wenchuan 5.12 Violent Earthquake. The disinfectants and insecticides, including HCH (hexachlorocyclohexane) and DDT (dichlorodiphenyltrichoroethane) as representative OCPs, could lead to serious environmental problems. In order to disclose the residues of HCH and DDT in soils following the Wenchuan 5.12 Violent Earthquake, surface soils in Dujiangyan City and Beichuan County were sampled in 2009. The samples were analyzed by GC/MS after pre- treatment by ultrasonic solvent extraction. It has been found that the concentra-tions of γ-HCH, β-HCH and 4,4'-DDT in soils of Beichuan County were 94–102.4, 14.1–36.1 and 2.9–4.3 times high their concentrations in those of the Wolong Nature Reserve, and the concentrations in soils of Dujiangyan City were 52.4–61.6, 8.8 –45.3 and 5.4–6.2 times high their concentrations in soils of the Wolong Nature Reserve, respectively.

文摘Automated recognition of violent activities from videos is vital for public safety,but often raises significant privacy concerns due to the sensitive nature of the footage.Moreover,resource constraints often hinder the deployment of deep learning-based complex video classification models on edge devices.With this motivation,this study aims to investigate an effective violent activity classifier while minimizing computational complexity,attaining competitive performance,and mitigating user data privacy concerns.We present a lightweight deep learning architecture with fewer parameters for efficient violent activity recognition.We utilize a two-stream formation of 3D depthwise separable convolution coupled with a linear self-attention mechanism for effective feature extraction,incorporating federated learning to address data privacy concerns.Experimental findings demonstrate the model’s effectiveness with test accuracies from 96%to above 97%on multiple datasets by incorporating the FedProx aggregation strategy.These findings underscore the potential to develop secure,efficient,and reliable solutions for violent activity recognition in real-world scenarios.
文摘利用台风资料、海南灾情资料、再分析资料和多种统计分析方法,确定1967—2015年影响海南岛的15个强台风事件并探析海南岛强台风事件(Hainan violent typhoon event,HNVTE)的影响因子。结果表明,HNVTE发生的气候背景信息表现为多时间尺度因子的协同作用:1980年代后期西北太平洋副热带高压(以下简称“西北太平洋副高”)突变式变强可能为HNVTE的减少提供了年代际尺度背景,厄尔尼诺-南方涛动(El Ni o-Southern Oscillation,ENSO)和平流层准两年振荡(quasi-biennial oscillation,QBO)的共同作用提供了HNVTE变化的年际异常背景。西北太平洋副高突变前出现中等强度的La Ni a状态和突变后出现中等强度的El Ni o状态均有利于HNVTE发生,而平流层西风位相下低层强西风切变则会抑制这两种状态下的HNVTE活动。根据西北太平洋海面温度的年代际位相、ENSO循环位相及强度和QBO位相及强度构建的BEST-QBO协同作用指数能很好地识别HNVTE的发生,可为HNVTE的气候预测提供有用的信号。
文摘How gamma-ray bursts(GRBs),the most powerful and spectacular explosions known in the universe since the Big Bang,fuel their high-energy radiations?What kind of physical reactions can trigger and sustain such violent,energetic outflow?This has captivated astronomers.Over the past decades,thousands of GRBs have been observed;however,the origin and the product of the burst-the central celestial body,or the“central engine”,is still pending for identification.
文摘While the fall of Raqqa signalled the steady decline and“defeat”of the Islamic State(IS),it did not guarantee the end of its ideology of violent extremism.The possibility of the organisation reinventing itself in different and perhaps more lethal ways is very high.States,therefore,must adopt measures that are based on holistic,multi-stakeholder approaches rather than on military and securitised responses to counter and ultimately prevent the spread of violent extremist ideology.The countries of the Gulf have the advantage of a“youth bulge,”with almost half its population under the age of 30 years.This“youth bulge”is however a double-edged sword.This large pool of human capital could be a demographic dividend,if harnessed intelligently,while conversely it could prove to be a demographic disaster if timely and plausible solutions to the various issues faced are not provided.This paper will explore ways in which preventing and countering violent extremism(P/CVE)through education could be achieved by including a variety of stakeholders from faith based organisations,the corporate sector,media and academia in the formulation of appropriate educational responses which take into account issues like culture,identity and religiosity.These re-education programmes should form an integral part of P/CVE policies,thereby providing the much needed psycho-social angle to an otherwise hard security-driven discourse.It is against this rationale that this paper makes a case for P/CVE through education,encompassing the formal,informal and non-formal levels,as one of the possible means for promoting and fostering a peace process in the Gulf.

文摘An unstructured mesh Reynolds-averaged Navier-Stokes(RANS)solver has been developed for numerical simulation of violent sloshing flows inside a tank with complicated inner structures.The numerical solver employs the unstructured multi-dimensional tangent hyperbolic interface capturing method(UMTHINC)for free-surface capturing combined with various turbulence models.The sloshing motion is numerically modeled using the body-force method which introduces a source term into the momentum equation corresponding to the tank motion profile.Numerical simulations of the tank sloshing problems are performed for different test cases with various oscillation frequencies.The performance of the interface capturing method has been discussed and the effect of turbulence model choice on loading predictions is highlighted by studying several RANS models and analyzing its effect on fluid motion and impact pressure.Numerical simulations of the sloshing inside the tank with a vertical baffle has also been conducted and a discussion is provided on different numerical treatment of the baffle.

文摘Methamphetamine(MA),an extremely addictive synthetic stimulant,has quickly spread to become the most frequently used illicit drug in China.People with a history of chronic and heavy MA use have a high possibility of exhibiting schizophrenia-like psychotic symptoms,mainly delusions of reference,auditory hallucinations and cognitive deficits.These emerging findings suggest MA use increases aggression and violence and that there is a correlation between MA use and violence.However,it is unclear how to assess the capacity of criminal responsibility in“MA-induced”psychosis and how to set clear boundaries between schizophrenia and MA-induced psychosis when only limited and inconsistent evidence is available.Furthermore,a final persuasive differential diagnostic method based on improved understanding of schizophrenia and MA-induced psychotic disorders has yet to be developed.This paper will evaluate the epidemiology,social harm,and forensic psychiatric assessment of MA users,propose a future direction for the differential diagnosis between MA-induced psychotic disorders and schizophrenia,and put forward some practical solutions to assess the capacity of criminal responsibility of defendants with drug-induced psychotic disorder.
文摘A novel CFD approach based on adaptive mesh refinement（AMR） technique is being developed for numerical simulation of violent free surface flows. CIP method is applied to the flow solver and tangent of hyperbola for interface capturing with slope weighting（THINC/SW） scheme is implemented as the free surface capturing scheme. The PETSc library is adopted to solve the linear system. The linear solver is redesigned and modified to satisfy the requirement of the AMR mesh topology. In this paper, our CFD method is outlined and newly obtained results on numerical simulation of violent free surface flows are presented.
