ABSTRACT

This study compared the effect of interactive media-based cognitive behaviour, art, and music therapies in reducing depression in children who survived abduction in Nigeria. A randomized control trial was conducted using three randomly selected secondary schools in Northern Nigeria. The study sample comprised 450 children randomly divided into a control group of (n = 225) and an experimental group of (n = 225). The treatment group was further divided into three groups; cognitive behavior (n = 75), art (n = 75), and music (n = 75) therapy, respectively. According to the findings of this study, cognitive behaviour, art, and music therapies via interactive media are a successful intervention technique for treating the depression of schoolchildren who survived abduction in Nigeria. However, compared to art and music therapy, cognitive behaviour therapy is more effective at treating depression. To lessen the depression of children who survived kidnapped in Nigeria, we recommend adopting cognitive behavioural therapy.

ABSTRACT

PURPOSE: Post-traumatic stress disorder (PTSD) is a severe anxiety disorder that can develop due to exposure to any event that may result in psychological trauma. This study compared the effect of interactive audio-visual-based art and music therapy in reducing post-traumatic stress disorder in adolescents who survived abduction in Nigeria. METHODS: A quasiexperiment was carried out in two selected secondary schools in Northern Nigeria. The study sample comprised 470 students randomly divided into a control group of 235 and an experiment group of 235. The treatment group was further divided into art 118 and music 117 therapy groups, respectively. RESULTS: Results suggest that interactive audio-visual art therapy and music therapy is an effective intervention strategy for reducing the PTSD of school adolescents that have experienced kidnapping in Nigeria. However, art therapy is more effective in reducing PTSD than music therapy. DISCUSSION: We recommend the introduction of audio-visual-based music and art therapy to reduce the PTSD of adolescents that survived kidnapping in Nigeria. More focus should be made on art therapy, which is more effective in curtailing adolescents PTSD.

ABSTRACT

This study looked at how exposure to interactive TV-based music and art therapy could assist in reducing suicidal thoughts of secondary school female children who survived abduction in Nigeria. A quasi-experiment was carried out in three randomly selected secondary schools in Northern Nigeria. The study sample comprised 470 students divided into three groups to form control group 235, art therapy group 118 and music therapy group 117. Results suggest that participants exposed to interactive TV-based art therapy and music therapy reported a lower score for suicidal ideation compared to the control group that was not exposed to any form of therapy aside from routine clinic checkups. Specifically, those exposed to interactive TV-based art therapy reported a lesser suicidal ideation score than the music and the control group. We recommend the introduction of interactive TV-based music therapy and art therapy in reducing suicidal ideation among children that survived kidnapping in Nigeria.

ABSTRACT

BACKGROUND: Children constitute a nation's true asset. A country's future relies upon the proper development of its children, which necessitates a supportive environment and sufficient opportunities. Children, under the age of 18 years form a considerable percentage of India's population which imparts a huge responsibility for the nation. Everyday we come across news about a child going missing. The National Crime Record Bureau (NCRB) states that 73,138 children were reported missing overall in 2018. The prevalence increased by 8.9% in 2019, a worrisome situation. The cause behind children going missing is multi-dimensional like poverty, unemployment, loss of livelihood, natural calamities, social conflicts, and migration to urban areas. At present, missing children remain a neglected and non-urgent intervention area for everyone. Only the parents whose children are missing can feel the vacuum and sorrow of the situation. The sociologies of India's missing children merit dimensional and circumstantial examination. The sociological space into which a child goes missing is highly under-researched in India. This study helped in understanding the magnitude of missing cases across India based on existing literature and secondary sources. It also identified the potentially safe and worst areas with regard to missing children. The endemicity helped in identifying the changing trends in each of these areas of interest, which could serve as baseline data for policymakers and law enforcement alike. MATERIALS AND METHODS: This is a cross-sectional analytical type of study. The data of missing and unrecovered children for the past five years (2021-2017) were obtained from open government data portal (https://data.gov.in) and geospatial hotspot analysis was done using the Getis-Order-G statistics on the same using GeoPandas and PySAL libraries of python. The endemicity of missing cases was studied using hierarchical cluster analysis and self-organizing maps using Python. RESULTS: For boys, Uttar Pradesh, Rajasthan, and Madhya Pradesh remained consistent hotspots (high risk of missing cases) across all five years of study whereas Karnataka became a hotspot for 2020 and 2021. Among the cold spots (low risk of missing cases), Andaman and Nicobar Islands remained consistent cold spot across all five years of study and has emerged as a safe haven for boys. The missing girls' data reveals that Uttar Pradesh has consistently been the worst state for girls (along with their neighbors) as it possess the risk of girls going missing all through the study period with Chhattisgarh being included from 2019 onwards. Jharkhand, Gujarat, Sikkim, and Andaman and Nicobar Islands have consistently been cold spots across the board and have emerged as areas with low risk for missing girls. CONCLUSION: This study helps us in understanding the magnitude of missing cases across India and it also identifies which are potentially safe areas as well as worst areas with regard to missing children. The endemicity also helps us in identifying the changing trends in each of these areas of interest. This will serve as a great resource for policy makers and law enforcement alike.

ABSTRACT

This paper examines non-state infrastructures of vigilante violence in marginalized spaces in South Africa. I argue that car trunks, shacks, containers, and other everyday receptacles function as the underside of official institutions, such as prisons and police lock-ups, and bear historical imprints of the extrajudicial punishments inflicted on black bodies during colonialism and apartheid. I focus on two techniques: forcing someone into the trunk of a vehicle and driving them around to locate stolen property, and confinement in garages, shacks, containers, or local public spaces. Whereas in formerly 'whites only' areas, residents have access to insurance, guards, gated communities, fortified fences, and well-resourced neighbourhood watches, in former black townships and informal settlements, this is not the case. Here, the boot, the shack, the shed, the car, and the minibus taxi play multiple roles, including as vectors and spaces of confinement, torture, and execution. Thus, spatiotemporality affects both how penal forms permeate space and time, and how space and time constitute penal forms. These vigilante kidnappings and forcible confinements are not mere instances of gratuitous violence. Instead, they mimic, distort, and amplify the violence that underpins the state's unrealized monopoly over the violence inherent in its claims to police and punish.

ABSTRACT

Among the numerous indoor localization methods, Light-Detection-and-Ranging (LiDAR)-based probabilistic algorithms have been extensively applied to indoor localization due to their real-time performance and high accuracy. Nevertheless, these methods are challenged in symmetrical environments when tackling global localization and the robot kidnapping problem. In this paper, a novel hybrid method that combines visual and probabilistic localization results is proposed. Augmented Monte Carlo Localization (AMCL) is improved for position tracking continually. LiDAR-based measurements' uncertainty is evaluated to incorporate discrete visual-based results; therefore, a better diversity of the particle can be maintained. The robot kidnapping problem can be detected and solved by preventing premature convergence of the particle filter. Extensive experiments were implemented to validate the robustness and accuracy performance. Meanwhile, the localization error was reduced from 30 mm to 9 mm during a 600 m tour.

ABSTRACT

Both inter- and intragroup interactions can be important influences on behaviour, yet to date most research focuses on intragroup interactions. Here, we describe a hitherto relatively unknown behaviour that results from intergroup interaction in the cooperative breeding pied babbler: kidnapping. Kidnapping can result in the permanent removal of young from their natal group. Since raising young requires energetic investment and abductees are usually unrelated to their kidnappers, there appears no apparent evolutionary advantage to kidnapping. However, kidnapping may be beneficial in species where group size is a critically limiting factor (e.g. for reproductive success or territory defence). We found kidnapping was a highly predictable event in pied babblers: primarily groups that fail to raise their own young kidnap the young of others, and we show this to be the theoretical expectation in a model that predicts kidnapping to be facultative, only occurring in those cases where an additional group member has sufficient positive impact on group survival to compensate for the increase in reproductive competition. In babblers, groups that failed to raise young were also more likely to accept extragroup adults (hereafter rovers). Groups that fail to breed may either (i) kidnap intergroup young or (ii) accept rovers as an alternative strategy to maintain or increase group size. This article is part of the theme issue 'Intergroup conflict across taxa'.

ABSTRACT

Northern Nigeria is currently facing a twin crisis of both COVID-19 and insecurity. They have made it difficult for the people to follow government containment efforts to control the pandemic and also have impacted on the socioeconomic and health aspects of the society. We have discussed on the impact of insecurity amid COVID-19 in Northern Nigeria. It is opined that if the insecurity in Northern Nigeria is not tackled, it will expose the region to more escalation of cases and deaths. Thus, it is recommended that proactive steps should be implemented by all stakeholders concerned to tackle insecurity, particularly the government to revive the security architecture, provide an environment for training and retraining of all security personnel and enhancing intelligence gathering to pave the way for resolving this issue.

ABSTRACT

OBJECTIVE: Fetal abduction by maternal evisceration (FAMAE) cases are statistically rare but warrant closer scrutiny as planned homicides. This study reports lessons regarding abductor modus operandi, motivation, intent, planning, and the dynamics in the attack to inform public safety. METHODS: The fifteen FAMAE cases reported to the National Center for Missing and Exploited Children from 1987 to 2011 were reviewed. Court documents for the cases were retrieved, and investigators and attorneys were called to verify information where necessary. RESULTS: All abductors were female, between 19 and 40 years of age. Seven stages of the structure of the crime were identified: targeting and making contact with a pregnant woman, securing weapons, determining the location, subduing the mother, securing the newborn, disposing of the victim mother's body, and informing others that they birthed a child. CONCLUSION: The case histories analyzed demonstrate how FAMAE perpetrators target an unsuspecting pregnant woman, and entrap and murder her in the service of fetal kidnapping. Awareness of FAMAE promotes public safety from those who would do anything to claim they have borne a child.

ABSTRACT

On 8 June 1972, the Czechoslovak OK DNN aircraft carrier L410 Turbolet was delivered to the regular line Marianske Lazne - Prague to the Federal Republic of Germany. About 8 minutes after the launch from Marianske Lazne Airport, the likely head of the group of kidnappers threw the captain of the plane. During the fight with one of the passenger, the head of the group of kidnappers killed the captain of the aircraft by a shot from 7.65 mm pistol. Other members of the hijackers group attacked other passengers. After the aircraft captains death, the second pilot took command and landed at the sports club at Weiden. After the landing, the kidnappers were detained by the police. Ten kidnappers stayed in the Federal Republic of Germany. An airplane with other passengers and coffin of a shot captain landed in Prague Ruzyne the following day. On June 12, 1972, the re-autopsy of the captain of the aircraft was performed at the Central Military Hospital in Prague. Post-autopsy status was detected. In this re-autopsy, it was possible to reconstruct the fire channel only incompletely, because during the previous autopsy performed in Federal Republic of Germany was excised the shot wound left on the neck. The fire channel began with a hole in the skin 10 cm above the right breast nipple, continued to the left and slightly upward through the subcutaneous tissue, passed through the 2nd rib at the right at a distance of 4.5 cm from the sternum, continued the lower and inner sides of the right collarbone, flowing on the front the ring cartilage and the first ring of the trachea, and on the underside of the left lobes of the thyroid gland, passed on the front of the left common carotid and continued into the area of the left SCM. The exid shot hole was on the left half of the neck. The direction of the shotway canal from right side to left side was detectable only by the fragment of the 2nd rib, which was broken out to the left and inside. The cause of the captains death was a traumatic shock. The injury was caused by a short firearm of small stance. Additional factors of firing were not found on the skin, as well as no signs of gas pressure. At the request of the experts performing the autopsy, a copy of the autopsy protocol from Germany was sent to them by an autopsied doctor. Among other things, it was reported that a 6.5 cm under the lower end of the left ear was a transversely oval, 2.5 cm long and 1.2 cm wide, red-black dried place of the upper skin, from which center run out a little red blood. At the conclusion of the autopsy protocol, it was found that there was a shotgun injury at the left side of the neck and the right side of the chest. The entrance wound according to the sent copy of the autopsy protocol, lay on the left side of the neck, the bullet penetrated the neck muscles, broke the inner branch of the cervical artery, passed through the trachea, penetrated the collarbone, split the 2nd rib to the right about 2 cm next to the sternum and the right chest 10 cm above the breast the nipple stepped out of the body. The direction of the penetration of the projectile through the body therefore had the opposite orientation compared to the re- autopsy. On the basis of this finding, the expert opinion from the re-autopsy was supplemented in the sense that there is no evidence in the autopsy protocol from Germany for the conclusion of the shot on the left side of the neck. Both autopsy experts examined the space of the aircraft cabin. The inspection showed that from the left, that is to the neck, the captain of the aircraft could be hit only if the attacker held the pistol in his left hand in a completely unnatural position so that his forearm was pulled upward over the left shoulder of the captain just to the left of the cabin and a hand bent in the wrist at a steep angle down to the right. The position of the shooters hand would be more natural if the captain of the aircraft turned backward over his left shoulder and turned the hull to the left. But this would be completely useless because of the situation, as he would look into the left cabin wall. More natural would be turning right over his right shoulder. In that case, he could be hit on the right side of the chest. The shooting kidnapper committed suicide in a cell overnight from 12 to 13 January 1973. It is not possible, based on the information available, to decide exactly how the gunshot has been going on. Czech experts did not have clothing of the captain or conclusions about their examination, and the hole on the left side of the neck was cut out by the German expert and was not provided to the Czech party through the request. It may be considered strange that the autopsy in Germany was performed in this relatively serious case outside the renowned forensic medicine department.

ABSTRACT

Fifteen cases of Fetal Abduction by Maternal Evisceration (FAMAE) reported to the National Center for Missing and Exploited Children during 1987-2011 outline the findings from a review of the forensic psychiatric considerations and legal course of each of the cases. Most offenders confessed to law enforcement within a short time of being placed under arrest in statements reflecting a continued effort to manage impressions and minimize culpability. Psychiatric assessment is invariably central to the legal disposition of FAMAE cases, as the defendant's goal is to diminish the perception of culpability/criminal responsibility and mitigate sentencing. Of those sentenced in the United States, nine defendants received life without parole, two received the death penalty (one executed), and one received a minimum of 30 years. Two abductors committed suicide and were not sentenced. Proffered diagnoses at trial included psychogenic amnesia, pseudocyesis, dissociative disorder, and delusional disorder; however, these rarely stood up to court scrutiny. Psychiatric experts showed the greatest variance in diagnosis over what to call the feigned pregnancy. In addition to delusional disorder and dissociative disorder, pseudocyesis, factitious disorder/pregnancy, pseudopregnancy, schizophrenia, and PTSD were among the various diagnoses proposed. A differential diagnosis for many FAMAE offenders may also include borderline personality disorder. Future research accounting for those women claiming false pregnancy who do not become homicidal will clarify whether FAMAE is the extreme endpoint of a fertility identity disorder.

ABSTRACT

Resumen Este estudio se realizó con el objetivo de analizar qué factores están asociados a la comisión del delito de extorsión en el Distrito Fiscal de La Libertad- Perú. La metodología es cuantitativa, diseño descriptivo correlacional de corte transversal. Se revisaron 222 carpetas fiscales de las víctimas del delito de extorsión registradas de enero del 2017 a julio del 2018 en los distritos de Chepén y Trujillo. Asimismo, se encuestaron 523 personas que no fueron víctimas del delito de extorsión en los mismos distritos, dando un total de 745 participantes. Los resultados se determinaron aplicando el modelo de regresión logística, el cual muestra que, de los factores analizados, los factores sociales y económicos sí están asociados a la comisión del delito de extorsión, pero los factores biológicos no. Respecto a los factores sociales, el modelo establece que específicamente el estado civil y grado de instrucción son los que están asociados a la comisión del delito de extorsión. De los factores económicos analizados, el modelo establece que el nivel de ingresos, el lugar o zona de residencia y la tenencia de propiedades (vivienda y automóvil) están asociados a la comisión de este delito.


Abstract This study was performed to analyze the factors associated to committing the crime of extortion in the Prosecution District of La Libertad - Peru. For this purpose, the quantitative methodology was used, with a descriptive, cross-sectional and correlational design. Two hundred and twenty-two case files of victims of extortion were reviewed from January 2017 to July 2018 in the districts of Chepén and Trujillo. Furthermore, 523 people who were not victims of extortion in the same districts were interviewed, amounting to a total of 745 participants. The results were determined applying the logistic regression model, which demonstrated that, of the analyzed factors, the social and economic factors are associated to committing the crime of extortion, while biological factors are not. With respect to social factors, the model establishes that marital status and level of education are more specifically associated with the crime of extortion. Of the analyzed economic factors, the model establishes that level of income, place or area of residence and ownership of properties (housing and vehicles) are associated to this crime.

ABSTRACT

This paper proposes a novel multi-sensor-based indoor global localization system integrating visual localization aided by CNN-based image retrieval with a probabilistic localization approach. The global localization system consists of three parts: coarse place recognition, fine localization and re-localization from kidnapping. Coarse place recognition exploits a monocular camera to realize the initial localization based on image retrieval, in which off-the-shelf features extracted from a pre-trained Convolutional Neural Network (CNN) are adopted to determine the candidate locations of the robot. In the fine localization, a laser range finder is equipped to estimate the accurate pose of a mobile robot by means of an adaptive Monte Carlo localization, in which the candidate locations obtained by image retrieval are considered as seeds for initial random sampling. Additionally, to address the problem of robot kidnapping, we present a closed-loop localization mechanism to monitor the state of the robot in real time and make adaptive adjustments when the robot is kidnapped. The closed-loop mechanism effectively exploits the correlation of image sequences to realize the re-localization based on Long-Short Term Memory (LSTM) network. Extensive experiments were conducted and the results indicate that the proposed method not only exhibits great improvement on accuracy and speed, but also can recover from localization failures compared to two conventional localization methods.

ABSTRACT

Research has demonstrated that co-offending dyads and groups often use more violence than individual offenders. Despite the attention given to co-offending by the research community, kidnapping remains understudied. Stranger kidnappings are more likely than non-stranger kidnappings to involve the use of a weapon. Public fear of stranger kidnapping warrants further examination of this specific crime, including differences between those committed by solo and multi-offender groups. The current study uses National Incident-Based Reporting System (NIBRS) data to assess differences in use of violence among 4,912 stranger kidnappings by solo offenders and multi-offender groups using cross-tabulations, ordinal regression, and logistic regression. The results indicate that violent factors are significantly more common in multi-offender incidents, and that multi-offender groups have fewer arrests than solo offenders. The implications of these findings are discussed.

ABSTRACT

We study the impact of marriages resulting from bride kidnapping on infant birth weight. Bride kidnapping-a form of forced marriage-implies that women are abducted by men and have little choice other than to marry their kidnappers. Given this lack of choice over the spouse, we expect adverse consequences for women in such marriages. Remarkable survey data from the Central Asian nation of Kyrgyzstan enable exploration of differential birth outcomes for women in kidnap-based and other types of marriage using both OLS and IV estimation. We find that children born to mothers in kidnap-based marriages have lower birth weight compared with children born to other mothers. The largest difference is between kidnap-based and arranged marriages: the magnitude of the birth weight loss is in the range of 2 % to 6 % of average birth weight. Our finding is one of the first statistically sound estimates of the impact of forced marriage and implies not only adverse consequences for the women involved but potentially also for their children.

ABSTRACT

Contexto: Essa pesquisa tem como objetivo analisar a história de vida e trabalho dos bancários vítimas de sequestro e suas consequências psicossociais e laborais por meio da investigação das características da organização do trabalho bancário. Objetivo: Compreender, a partir da perspectiva dos bancários vítimas, o que significou a experiência do sequestro e apresentar propostas de promoção de saúde para essa população em risco. Método: Trata-se de uma pesquisa qualitativa a partir de entre-vistas em profundidade com quatro bancários vítimas de sequestro. As entrevistas foram transcritas pela pesquisadora com auxílio de um programa conhecido como VoiceNote II. Resultados: Os resultados obtidos demonstram o impacto psicossocial negativo do sequestro na vida das vítimas, agravado pelo inadequado manejo dessas ocorrências por parte dos bancos, intensificando as manifestações de transtornos psíquicos após o evento traumático. Conclusão: Este estudo espera contribuir para discussões com os atores sociais implicados e na revisão das formas de gestão e organização do trabalho dos bancos com vistas à preservação da segurança e saúde dos bancários. A gravidade desse tipo de violência ao trabalhador deveria também receber maior atenção da saúde e segurança públicas.


Background: The aim of the present study was to analyze the life and work history of bank employees who were victims of kidnapping and the psychosocial and work-related consequences of this event by investigating the characteristics of the organization of bank work. Aims: To understand what the experience of being kidnapped meant to the victims from their perspective and to describe proposals for health promotion targeting this high-risk population. Method: The present qualitative study was based on in-depth interviews conducted with four bank employees who were kidnapping victims. The interviews were transcribed by the investigator using program VoiceNote II. Results: The results demonstrate the negative psychosocial impact of kidnapping on the victims' lives, made even worse by the bank inadequate handling of these occurrences, resulting in intensification of the manifestations of psychic disorders after the traumatic event. Conclusion: The authors hope to contribute to discussions with the social actors involved, as well as to the revision of management and organization of work in banks so as to preserve the safety and health of bank employees. The severity of this type of violence against workers should also receive greater attention from public health and safety agencies.

ABSTRACT

Selten's game is a kidnapping model where the probability of capturing the kidnapper is independent of whether the hostage has been released or executed. Most often, in view of the elevated sensitivities involved, authorities put greater effort and resources into capturing the kidnapper if the hostage has been executed, in contrast with the case when a ransom is paid to secure the hostage's release. In this paper, we study the asymmetric game when the probability of capturing the kidnapper depends on whether the hostage has been executed or not and find a new uniquely determined perfect equilibrium point in Selten's game.

ABSTRACT

Although kidnapping is common in war-torn countries, there is little research examining its psychological effects. Iraqi refugees (N = 298) were assessed upon arrival to the U.S. and 1 year later. At arrival, refugees were asked about prior trauma exposure, including kidnapping. One year later refugees were assessed for posttraumatic stress disorder (PTSD) and major depression disorder (MDD) using the SCID-I. Individual resilience and narratives of the kidnapping were also assessed. Twenty-six refugees (9 %) reported being kidnapped. Compared to those not kidnapped, those who were had a higher prevalence of PTSD, but not MDD, diagnoses. Analyses examining kidnapping victims revealed that higher resilience was associated with lower rates of PTSD. Narratives of the kidnapping were also discussed. This study suggests kidnapping is associated with PTSD, but not MDD. Additionally, kidnapping victims without PTSD reported higher individual resilience. Future studies should further elucidate risk and resilience mechanisms.
