Application of modified discontinuous deformation analysis to dynamic modelling of the Baige landslide in the Jinsha River

Accurate dynamic modeling of landslides could help understand the movement mechanisms and guide disaster mitigation and prevention.Discontinuous deformation analysis(DDA)is an effective approach for investigating landslides.However,DDA fails to accurately capture the degradation in shear strength of rock joints commonly observed in high-speed landslides.In this study,DDA is modified by incorporating simplified joint shear strength degradation.Based on the modified DDA,the kinematics of the Baige landslide that occurred along the Jinsha River in China on 10 October 2018 are reproduced.The violent starting velocity of the landslide is considered explicitly.Three cases with different violent starting velocities are investigated to show their effect on the landslide movement process.Subsequently,the landslide movement process and the final accumulation characteristics are analyzed from multiple perspectives.The results show that the violent starting velocity affects the landslide motion characteristics,which is found to be about 4 m/s in the Baige landslide.The movement process of the Baige landslide involves four stages:initiation,high-speed sliding,impact-climbing,low-speed motion and accumulation.The accumulation states of sliding masses in different zones are different,which essentially corresponds to reality.The research results suggest that the modified DDA is applicable to similar high-level rock landslides.

The Violent Redemption Theme in A Good Man is Hard to Find

Flannery O’Connor is one of the representative figures of American Southern writers.Being recognized as the most outstanding writer of the American South after Faulkner,she has great influence in the literary world.Her works are always shrouded in a strange and grotesque atmosphere and full of death as well as religious metaphors.The protagonists are a series of American Southern freaks struggling with the crisis of spiritual belief.The protagonists of her novel A Good Man is Hard to Find are a hypocritical believer in the world of sinners and a lost man suffering in the midst of real sin,thus O’Connor uses the highest form of violence-death to bring ultimate redemption to them.In people’s conception,violence and redemption are often opposite to each other,but O’Connor uses bloody and violent plots to explore the theme of religious salvation,integrating and unifying the two contrary concepts to form her unique and profound violent redemption writing.

Detection and Mapping of Violent Crime Hotspots in Southwestern Nigeria

The increasing rate of insecurity in Nigeria, especially the southwest requires a paradigm shift from popular approach to crime hotspots detection. 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.

Downscaling and Disaggregating NAO-conflict Nexus in Pre-industrial Europe

Recently, the desiccation effect of the North Atlantic Oscillation(NAO) is found to be positively correlated with violent conflict in pre-industrial Europe, with agricultural shrinkage and its subsequent economic shocks to be their causal link. However, it remains unexplored whether the correlation persists if the study period is extended backward in time, a different definition of violent conflict is applied, or the relationship is examined at lower geographic levels. In this study, we based on 835 internal disturbance incidents in Europe during 1049–1800 to conduct long-temporal and multi-scalar examination on the NAO-conflict nexus. ′Time-series′ and ′panel data′ disaggregation approaches, together with Granger Causality, Multiple Regression, and Survival Analyses were applied to verify the nexus quantitatively. Results show that the positive NAO-conflict correlation was significant at the continent and physiographic zone levels. During the positive NAO phases, the annual probability of internal disturbance outbreak increased by 70.0% in the southern Europe and the Mediterranean, a zone most affected by the NAO-induced desiccation effect. Yet, the NAO-conflict correlation was rather inconsistent when it was downscaled to the sub-regional level. Moreover, the NAO-conflict correlation was inflated under the time-series approach, while the panel data approach demonstrated the region-specific nature of the NAO forcing more clearly. The associated implications in examining climate-conflict nexus are discussed. Our findings may be crucial in examining violent conflict in the northwestern Africa, a highly agricultural region affected by the NAO.

The pressure field in the liquid column in the tube-arrest method

We have been using the method of tube-arrest as a means of producing transient single cavitation bubble. In the present paper we seek to comprehend the mechanism of production and inquire into the structure of the ab initio pressure field in the arrested liquid column. The generated pressure wave is shown by combining the theoretical analysis with the experimental observation to be a slightly varied version of water hammer. With relatively clean liquid, the magnitude of the tension peak generating the TSB is likely to reach of several millions Pa. It is also shown that the so generated cavitation bubble originating from the gas-containing bulk liquid is in ‘violent’ motion.

Anomaly Based Camera Prioritization in Large Scale Surveillance Networks

Digital surveillance systems are ubiquitous and continuously generate massive amounts of data,and manual monitoring is required in order to recognise human activities in public areas.Intelligent surveillance systems that can automatically identify normal and abnormal activities are highly desirable,as these would allow for efficient monitoring by selecting only those camera feeds in which abnormal activities are occurring.This paper proposes an energy-efficient camera prioritisation framework that intelligently adjusts the priority of cameras in a vast surveillance network using feedback from the activity recognition system.The proposed system addresses the limitations of existing manual monitoring surveillance systems using a three-step framework.In the first step,the salient frames are selected from the online video stream using a frame differencing method.A lightweight 3D convolutional neural network(3DCNN)architecture is applied to extract spatio-temporal features from the salient frames in the second step.Finally,the probabilities predicted by the 3DCNN network and the metadata of the cameras are processed using a linear threshold gate sigmoid mechanism to control the priority of the camera.The proposed system performs well compared to state-of-theart violent activity recognition methods in terms of efficient camera prioritisation in large-scale surveillance networks.Comprehensive experiments and an evaluation of activity recognition and camera prioritisation showed that our approach achieved an accuracy of 98%with an F1-score of 0.97 on the Hockey Fight dataset,and an accuracy of 99%with an F1-score of 0.98 on the Violent Crowd dataset.

Prevalence, Pattern and Factors Associated with Psychiatric Disorders among Persons Arrested for Violent Crimes in Ife/Modakeke Area, Southwestern Nigeria

Background: Association between violence and mental disorders has contributed immensely to the stigma associated with mental illness in the society;because people erroneously see mentally ill individuals as dangerous, they will not want to associate with them. 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.

Change of the mode of failure by interface friction and width-to-height ratio of coal specimens

Bumps in coal mines have been recognized as a major hazard for many years. These sudden and violent failures around mine openings have compromised safety, ventilation and access to mine workings.Previous studies showed that the violence of coal specimen failure depends on both the interface friction and width-to-height（W/H） ratio of coal specimen. The mode of failure for a uniaxially loaded coal specimen or a coal pillar is a combination of both shear failure along the interface and compressive failure in the coal. The shear failure along the interface triggered the compressive failure in coal. The compressive failure of a coal specimen or a coal pillar can be controlled by changing its W/H ratio. As the W/H ratio increases, the ultimate strength increases. Hence, with a proper combination of interface friction and the W/H ratio of pillar or coal specimen, the mode of failure will change from sudden violent failure which is brittle failure to non-violent failure which is ductile failure. The main objective of this paper is to determine at what W/H ratio and interface friction the mode of failure changes from violent to non-violent. In this research, coal specimens of W/H ratio ranging from 1 to 10 were uniaxially tested under two interface frictions of 0.1 and 0.25, and the results are presented and discussed.

A New Interface Identification Technique Based on Absolute Density Gradient for Violent Flows

An identification technique for sharp interface and penetrated isolated particles is developed for simulating two-dimensional,incompressible and immiscible two-phase flows using meshless particle methods in this paper.This technique is based on the numerically computed density gradient of fluid particles and is suitable for capturing large interface deformation and even topological changes such as merging and breaking up of phases.A number of assumed particle configurations will be examined using the technique,including these with different level of randomness of particle distribution.The tests will show that the new technique can correctly identify almost all the interface and isolated particles,and also show that it is better than other existing popular methods tested.

Medicolegal autopsies in children: Experience of a department of Legal Medicine in Brazil

Purposes: The purpose of this study was to determine the pattern of mortality in children’s Federal District. Knowledge of the epidemiology of injuries is essential for planning, implementation and evaluation of preventive measures. Methods: We analyzed the forensic examination documents of all children under 12 years sent to the IML-DF, during 2010. The data analyzed included age, gender, cause of death (i.e.natural or external), mechanism of death (traffic accident, asphyxia, firearm injuries, poisoning, heat injuries) and the medical cause of death. Results: A large number of children (n = 123 total;n = 71 males, n = 52 females) were examined in the IML-DF, Brasília, Brazil. Mean age was 37.96 months, with a median of 12 months, and 21% of children were younger than 1 month. There were 62 cases (33 males and 29 female) classified as natural deaths. The average age for natural deaths was 18.72 months. Most cases of natural death occurred in the first year of life (n = 50), being prevalent in the first month of life (n = 24). Among the 62 cases analyzed, six were stillborns, 13 suffered intrauterine fetal distress (e.g. placental insufficiency, prematurity and meconium aspiration), 36 had lung problems (e.g. Acute respiratory distress syndrome (ARDS), bronchopneumonia, pulmonary hemorrhage, interstitial pneumonitis and infant respiratory distress syndrome (IRDS)), five had neurologicalproblems (e.g. hydrocephalus, hydranencephaly,convulsive seizures and meningitis) and two had undetermined cause of death. There were also isolated cases of heart disease, leukemia, diabetic ketoacidosis, peritonitis causedby acute appendicitisand amniotic bandsyndrome. There were 61 cases of deaths from external causes, as a consequence of the following: blunt instrument, firearm, physical agent (i.e.heat), physicochemical agent (i.e.asphyxia) and chemical agent (i.e.poisoning). Conclusions: The profile of deaths from external causesin this developing country follows a trend similar to trends reported in the literature for other developing countries. The majority of deaths are accidental, with traffic accidents being the most frequent cause, followed by asphyxia (i.e.aspiration of gastric contents and drownings). Sporadic cases of poisoning, injuries from firearms, accidents and fires also occur.

Aesthetic Criticism of the Spatial Violence in The Hunger Games

The Hunger Games, a current popular dystopian fiction written byAmerican writer Suzanne Collins, reveals the social crises of the post-capitalism time.It stirs up the harsh criticism for its many violent depictions, but it is the depictions ofviolence that make it special. From a critical viewpoint of aesthetics of violence, thispaper tries to use the theory of violence of post-Marxist Slavoj Zizek to analyze anddig out that the essential root of the crises in the novel is the capitalism system itselfin the post capitalist era. The extreme desire of capitalism is to occupy extreme capitalspace that leads to the building up of the totalitarian governance at the base of spatialviolent politics in the novel. The spatial isolation becomes the most necessary devicefor making biggest profits; while violence becomes the most effective security toremain the spatial isolation. The close union of multiple violence and spatial isolationbecomes the strongest foundation of the totalitarianism of capitalist society. Then itbecomes the impressive theme of the aesthetics of violence of the novel—how thegoverned can employ the violence of the other’s to break the spatial isolation anddestroy the totalitarian system of the social mainstream to win back their own liberty.Therefore, the aesthetics of violence in the novel is full of power of critical aestheticswith violence against violence. Based on such critical aesthetics of violence, theforces of self-consciousness and self-activity of the disciplined others are awakeningfor their subjective rights on the way when violence against violence.

Variables of Suicidal Behavior in Tenerife Years 2011-2012: Proposals for the Prevention

Suicide is treated by society as a taboo subject despite it being the leading cause of unnatural death in Spain. The Tenerife Province is ranked 16th among the 52 Spanish provinces for its suicide rate. From 2007 till 2010, the rate increased from 2007 to 2008, then dropped in 2010. Slight rise occurred in suicide rates in 2010. This rate increased from 2007 to 2008, with a decrease of rate in 2010. Slight rise occurred in suicide rates in 2010. In 2013 the province saw 75 suicides per year. 90% - 98% of suicides are closely related to mental disease with the remaining 10% associated with different poor causes of the subject, according to bibliography. In this retrospective study, it has been found that the highest risk rests with men over 40 years of age in the central and southern part of the island. Among the forms of suicide reported, the most common is hanging followed by jumping from a height. It’s important to understand the reasons behind suicidal behavior from a psychosocial perspective, taking into account “unsafe” indicators and individual profiles. The lethal nature of a suicide attempt also depends on the form of suicide adopted and the possibility of a rescue. Specific protocols to prevent suicide should be promoted and discussed between health and social services.

Water Scarcity and Violent Conflict in International Relations＇ How Process Tracing Contributes to Demystify this Alleged Causal Relationship The Rio Grande-Colorado Case

In the last few decades, water scarcity and its implications to economic, social and political dimensions has become a hot topic, especially for research agendas that try to establish a causal relationship with violent conflicts. 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.

Hiperreal Dimension of Dying： Reception of the Phenomenon by Jean Baudrillard, Zuzanna Janin, and Bogna Burska

The first part of the paper presents the philosophical concept of Jean Baudrillard in which the issues of death and dying constitute an essential theme. Contemporary times in which the human condition seems to be extremely difficult are presented in a somber way. Isolation from nature results in the existence filled with fear of death. Natural death is a mentally inconceivable occurrence, an embarrassing phenomenon, and therefore unworthy of being remembered. Only sudden, spectacular death creating media hype seems to be meaningful and worth paying attention to. Instant death is set in opposition to slow death which is also called postponed death. Death in the heat of work, duties, obligations, and prohibitions is the death inflicted at the request of both an employee and an employer. Work rewarded with payment is an act of temporary suspension of death. Burdened with work, people forget about the debt they have incurred from nature. A contemporary employee does not deserve death and instant death is only act of salvation, the act of free will. The second part of the paper focuses on artistic activity of Zuzanna Janin and Bogna Burska. Both artists deal with an issue of media death using different means of expression. Spinning their narratives of intimate decaying and media rage in a public space, they correspond with the Baudrillard＇s philosophical thought.

Hemingway: What Does Death Mean?——A Preliminary Analysis of The Snows of Kilimanjaro

Some critics have pointed out that Hemingway gravely handicap-ped himself by dealing with violent action rather thanacts of intelli-gence.This idea is not right because it does not suit well with allhis works. The Snows of Kilimanjaro,the short story we are discussing here,is something about “the act of intelligence”。It shows
