Terror, religion och radikalisering - exempel på bakomliggande riskfaktorer i förbrytarnas psyke och tidigare liv. : - En kvalitativ studie med utgångspunkt i Lewis R. Rambos omvändelseteori.

Kjaergaard, Fabian January 2019 (has links)
The purpose and aim of this research was to analyze if Lewis R. Rambos conversion the- ory can be applied to describe religious radicalization towards violent Islamic terrorism or not. The research has analyzed and investigated if there are any differences or similarities, regarding risk factors and existential dimensions before the attacks of three terrorists; Rakhmat Akilov, Mohamed Bouhlel and Salman Abedi. The report further considers what role Melder ́s eight existential dimensions play in violent Islamic radicalization. The analyzis is based on a deductive method where, as said above, the conversion theory, existential dimensions and risk factors are used to answer the research questions. This study analyses and encodes the material by hand with paper and pen, even though the program “OpenCode” is more commonly used in a thesis of this proportion, due to it provided a more flexibility. The conclusion of this study is that Rambo ́s theory can elucidate violent reli- gious Islamic radicalization but as the theory tends to be too broad and vague it should be used in combination with other theories to be able to fully explain the conversion. Other- wise the theory tends to be too broad and vague. Results of analyzing the risk factors and existential dimensions, shows that there are more similarities between the three terrorists than differences and that the existential dimensions do play an important role in the religious radicalization even though this theo- ry also can be to broad and vague because of a tendency by the dimensions to overlap.

Atitudes de enfermeiros de serviços de urgência e emergência psiquiátricas frente ao comportamento violento / Nurse\'s attitudes in urgency psychiatric health services toward violent behavior

Dias, Maraina Gomes Pires Fernandes 06 June 2017 (has links)
Introdução: A alta prevalência de transtornos mentais na população geral pode refletir no aumento de pessoas nos serviços de emergência de hospitais gerais em sua maioria apresentando queixas de sintomas de um transtorno mental ou de alteração do comportamento. O comportamento violento pode estar associado ao transtorno mental e a agressão por parte desses indivíduos é considerado um problema grave que vem sendo vivenciado nos serviços de saúde, principalmente nas unidades psiquiátricas de curta permanência. Por passarem mais tempo na interação com o paciente, o enfermeiro e a equipe de enfermagem ficam sujeitos à agressão derivada do comportamento violento. A abordagem que a equipe irá adotar depende das suas crenças e atitudes diante das causas desse tipo de comportamento, pois, as mesmas afetarão na qualidade da assistência prestada ao indivíduo e os possíveis danos físicos e psicológicos ao próprio profissional. Objetivo: verificar as atitudes e visões de manejo de enfermeiros de Serviços de atendimento em Urgência e Emergência Psiquiátrica frente ao comportamento violento. Método: Trata-se de um estudo descritivo, exploratório e transversal realizado em 17 serviços públicos referenciados de atendimento psiquiátrico da cidade de São Paulo com uma amostra de 185 enfermeiros que trabalhavam nesses locais. Para coleta de dados foram utilizados a The Management of Aggression and Violence Attitude Scale (MAVAS-BR) e um questionário com dados sociodemográficos. Para análise, os dados foram agrupados em um banco construído no Statistical Package for Social Sciences onde se realizou análise exploratória com frequência absoluta e relativa e medidas de locação (média/mediana) e dispersão (desvio-padrão) para cada item e dos quatro fatores da escala. Para interpretação, quanto menor a média mais a concordância com o fator ou item da escala. Resultados: As atitudes dos enfermeiros estão mais relacionadas aos modelos externo e situacional ou interacional de explicação para o comportamento violento, os participantes mostraram-se mais favoráveis com utilização de métodos de controle para manejo do mesmo. Referente às visões de manejo, concordaram com o uso dos manejos de controle que podem indicar fatores como falta de conhecimento dos enfermeiros em utilizar os manejos não físicos e escassez de recursos humanos nos serviços de saúde. Conclusão: Esse estudo fornece subsídios para elaboração de estratégias educacionais para que o enfermeiro adquira conhecimento e segurança nas intervenções frente a pacientes que apresentem comportamento violento, sugerindo que novas pesquisas sejam realizadas sobre esse fenômeno ainda pouco explorado no contexto brasileiro e latino Americano. / Introduction: The high prevalence of mental disorders in the general population may reflect an increase of people in general hospital emergency services, in which mostly of them presenting complaints of symptoms of a mental disorder or behavioral disorder. Violent behavior may be associated with mental disorder and the aggression on the part of these individuals is considered a serious problem that is being experienced in the health services, especially in the short-stay psychiatric units. Because one will spend more time interacting with the patient, the nurse and a nursing staff members are subject to aggression derived from violent behavior. The approach adopted by the members of the nursing staff will depend on their beliefs and attitudes towards the causes of this type of behavior, cause these kind of behavior will affect the assistances quality provided for the individual and may cause physical and psychological damage for the professionals themselves. Objective: to verify the nurses attitudes and views towards violent behaviour in the urgent care and psychiatric. Method: This is a descriptive, exploratory and cross-sectional study carried out in 17 public services referenced in psychiatric care in the city of São Paulo, with a sample of 185 nurses who worked in these places. For the data collection the management attitude scale of aggression and violence (MAVAS-BR) \"and a questionnaire with sociodemographic data were used. For analysis, the data were grouped in a bank built in the Statistical Package for Social Sciences where an exploratory analysis was carried out with absolute and relative frequency and measurements of lease (mean / median) and dispersion (standard deviation / quartiles / minimum / maximum) for each item and each of the four scale factors. For interpretation, the lower the mean, the greater the agreement with the scale factor or item. Results: Nurses\' attitudes are more related to external and situational or interactional models of explanation for violent behavior, the participants were found to be more favorable to the use of control methods to manage it. Regarding management visions, they agreed on the use of control measures that may indicate factors such as lack of knowledge of nurses to use non-physical management and shortage of human resources in health services. Conclusion: This study provides support for the elaboration of educational strategies so that the nurse can acquire knowledge and safety in the interventions against patients who present violent behavior, suggesting that new researches have to be done on this phenomenon still little explored in the Brazilian and Latin American context.

Humor vítreo: uma alternativa para investigação de drogas de abuso postmortem / Vitreous humor: an alternative drug investigation in postmortem samples

Peres, Mariana Dadalto 27 February 2015 (has links)
O humor vítreo (HV) é um gel aquoso, transparente e incolor, situado entre o cristalino e a retina. Ele pode ser uma ferramenta para determinação de drogas de abuso, sobretudo quando é impossível fazer a determinação em sangue devido à sua ausência ou sua deterioração, por exemplo em casos de exsanguinação, embalsamento e carbonização. As drogas e seus metabólitos passam para o HV por difusão passiva e, de modo geral, a concentração dos analitos no HV é similar às concentrações obtidas no sangue. A cocaína e a benzoilecgonina são facilmente detectadas na matriz. Por outro lado, a difusão da morfina é bem limitada. O maior interesse do estudo de opioides é a análise de 6-acetilmorfina, que pode diferenciar o uso de heroína e morfina. O delta-9-tetrahidrocanabinol é uma molécula muito polar e fortemente ligada a proteínas plasmáticas, o que limita a sua difusão para o HV. Entre as anfetaminas, a metilenodioximetanfetamina e a metanfetamina são as moléculas mais estudadas no HV. Foi desenvolvido e validado um método utilizando GC-MS para análise simultânea de cocaína, anfetaminas, opioides, canabinoides e respectivos metabólitos em HV. Os analitos de interesse foram extraídos do HV utilizando extração em fase sólida e analisadas por GC-MS, utilizando o modo de aquisição SIM. A faixa de linearidade foi de 10 a 1000 ng/mL para todos os analitos, com exceção do éster de metilanidroecgonina (10 a 750 ng/mL). A exatidão variou de 95,6 a 104,0%, a precisão inter-ensaio variou de 1,2 a 10,0% e a precisão intra-ensaio foi menor que 10,4% para todos os analitos. O limite de quantificação para todas as drogas foi de 10 ng/mL e a recuperação variou de 70,4 a 100,1% para compostos básicos e neutros, entretanto os compostos ácidos apresentaram baixa recuperação - menor que 40%. A dosagem de etanol foi realizada por GC-FID e extração por headspace. Os métodos validados foram aplicados em 250 amostras de HV coletadas de vítimas de morte violentas nos anos de 2011 e 2012 que foram necropsiadas no Departamento Médico Legal de Vitória - ES. A maioria das vítimas era do sexo masculino (85,4%) e a causa mais comum de morte foi homicídio (46,2%), destes, 89,5% foram mortos por disparo de arma de fogo. Os acidentes de trânsito corresponderam a 44,1%; suicídio, 2,4%; e outras mortes totalizaram 7,2% das amostras. Substâncias psicoativas (álcool e drogas) foram positivas em 60,4% dos casos. Em 23,2% das amostras foi quantificada cocaína e/ou seu metabólito, e em um terço destes foi identificado o uso de crack. O álcool estava presente em 19,2% dos casos e a associação entre cocaína e álcool em 12,8% dos casos. Outras drogas incluíram anfetaminas (13 casos) e codeína (1 caso). Quando comparadas as concentrações das drogas pesquisadas no sangue e HV, a anfetamina e metanfetamina mostraram boa correlação entre as duas matrizes. A 6-acetilmorfina encontrada no HV foi utilizada para demonstrar o uso de heroína, uma vez que as concentrações foram mais altas do que no sangue. Entretanto, o HV não pode ser utilizado como amostra alternativa para detecção de canabinoides. / Vitreous humor is the aqueous gel located between the lens and retina. Vitreous humor is a useful alternative postmortem matrix for the detection of drugs, particularly in death investigations where postmortem blood is not available or is of limited quality or quantity (e.g. after hemorrhagic shock, burns, embalming or decomposition processes). Drugs and their metabolites enter the vitreous humor by passive diffusion from blood across the blood-vitreous barrier. Vitreous humor concentrations are often similar to the drug concentrations in the circulation blood. Cocaine and benzoylecgonine are easily detected in this matrix. On the order hand, morphine diffusion is limited. The interest in opiates is due to 6-acetylmorphine, which is stable in vitreous humor and can confirm heroin abuse. Drugs that are highly protein-bound, such as THC, achieve lower vitreous humor concentrations as only the free fraction can cross the blood-vitreous barrier. Methamphetamine and methylenodioxymetamphetamine are also detected in vitreous humor. A GC-MS method for simultaneous analysis of cocaine, amphetamines, opiates, cannabinoids and its metabolites in vitreous humor was developed and fully validated. Vitreous humor samples were extracted using solid phase extraction and analyzed by GC-MS in SIM mode. For all analytes the linearity ranged from 10 to 1000 ng/mL, excepted for anydroecgonine methylester which ranged from 10 to 750 ng/mL. Inter-assay imprecision ranged from 1.2 to 10.0% and intra-assay imprecision was less than 10.4% for all analytes at all QC concentrations. Accuracy ranged from 95.6 to 104.0% and recoveries ranging from 70.4 - 100.1% for basic and neutral compounds, the acids compounds had poor recovery (less than 40%). The limits of detection were up to 1.0 ng/mL. Ethanol was quantified by headspace extraction and GC-FID. The validated methodology was applied to 250 vitreous humor samples collected from violent death victims between 2011 and 2012 in the Departamento Médico Legal de Vitória - ES. Most of the victims were male (85.4%) and the most common cause of death was homicide (46.2%), in which 89.5 occurred by firearm shot. Traffic accident represented 44.1%, suicide 2.4% and other deaths 7.2%. Psychoactive substances (alcohol and?or drugs of abuse) were positive in 60.4% of the cases. Cocaine was quantified in 23.2% of the samples and one third was positive for crack cocaine. Ethanol was present in 19.2% of the cases and the association between cocaine and alcohol in 12.8%. Other drugs included amphetamines (13 cases) and codeine (1 case). When comparing the drug concentrations in blood and vitreous humor, amphetamine and methamphetamine showed a good correlation. 6-acetylmorphine in vitreous humor can demonstrate heroine abuse and its concentration is higher in vitreous humor than in blood. However, vitreous humor is not a good matrix for the detection of cannabinoids.

Ambulanspersonals erfarenheter av hot och våld

Alsbäck, Patrik, Bergén, Thomas January 2013 (has links)
Hot och våld inom ambulanssjukvård är ett arbetsmiljöproblem såväl nationellt som internationellt. Ambulanssjukvården är den första länken i vårdkedjan och ställs inför många olika utmaningar varav hot och våld kanske är den största av dem alla då personalen som är där för att hjälpa istället är den som behöver hjälp. Forskningen inom området är begränsad och uteslutande kvantitativ vilket är ett problem då fenomenet är en högst subjektiv upplevelse. Syftet med studien var att beskriva ambulanspersonalens erfarenheter av hot och våld inom ambulanssjukvården. Metoden var empirisk med kvalitativ ansats och datainsamlingen bestod av intervjuer. Resultatet visar att hot och våld inom ambulanssjukvården har stor påverkan på personalen såväl psykiskt som fysiskt. Fenomenet är ofta oförutsägbart och därför svårt att skydda sig mot men med hjälp av kroppsspråk och planering är det möjligt att förebygga hot och våld. Sociala problem samt den egna utrustningen och attityden upplevs som möjliga orsaker till att personalen utsätts för övergrepp. Den publicerade forskningen inom ambulanssjukvård har aldrig tidigare undersökt hur individerna bakom siffrorna i statistiken upplever hur det är att utsättas för hot och våld i yrket. Att ta del av ambulanspersonalens erfarenheter av fenomenet är således ny kunskap som belyser problematiken ur ett annat perspektiv vilket kan bidra till att medvetenheten om hot och våld ökar hos både personal, arbetsgivare samt högskolor och universitet. / Program: Specialistsjuksköterskeutbildning med inriktning mot ambulanssjukvård

Territórios da paz, do crime e da violência no Bairro Santa Tereza do município de Porto Alegre-RS

Teixeira, Janaína Costa January 2016 (has links)
Este trabalho está centrado na análise dos fenômenos socioespaciais que envolvem a criminalidade violenta no meio urbano. Busca-se investigar a relação entre o aumento da violência letal e os elevados índices de desigualdade social nos últimos 30 anos. O trabalho trata respectivamente das causas da violência urbana, das relações do crime e da violência com o espaço, além da participação dos jovens nas ações violentas e no trabalho do tráfico de drogas como fator decisivo na elevação das taxas de letalidade juvenil. Selecionamos o bairro Santa Tereza, por tratar-se de uma região conflituosa no município de Porto Alegre - RS, como objeto de estudo de caso, visto que concentra características de uma sociabilidade violenta. Investigamos as relações de pertencimento nas comunidades e o medo dos lugares em virtude do aumento da criminalidade nos centros urbanos. Da mesma forma, consideramos as causas do aumento da violência como sendo um dos fatores de repulsão dos espaços de uso comum e promotor de novas territorialidades a partir do esgarçamento do tecido sócio espacial. / This work focuses on the analysis of socio-spatial phenomena involving violent crime in urban areas. The aim is to investigate the relationship between the increase in lethal violence to high levels of social inequality in the last 30 years. The work deals respectively of the causes of urban violence, crime and violence relations with the space on the participation of young people in violent actions and the work of drug trafficking as a decisive factor in the rise of juvenile mortality rates. We selected Santa Tereza district, because it is a conflictive region in the city of Porto Alegre - RS, as a case study object as it focuses characteristics of a violent sociability. We investigated the relationships of belonging in communities and the fear of places due to the increase of crime in urban centers. Similarly we consider the causes of increasing violence as one of repulsion factors of spaces for common use and promoter of new territoriality from the fraying of the socio-spatial fabric.

Impulsivity in forensic populations

Alford, Max January 2018 (has links)
Purpose: The systematic review summarised the research investigating potential risk factors for impulsive behaviours in forensic populations. The empirical study examined the predictive utility of clinician rated, self-report and behavioural measures of impulsivity in detecting violence and antisocial behaviour in forensic mental health inpatient settings. Method: The review is comprised of 9 studies identified through electronic database searches using a structured search strategy and predetermined inclusion criteria. The empirical study employed a cross-sectional design using retrospective and prospective statistical analysis. Forty-three participants were recruited from secure forensic mental health inpatient settings across Scotland and data collected from clinician rated, self-report and behavioural measures of impulsivity. Results: The review found original evidence to suggest that traumatic brain injury, substance and alcohol misuse, trauma and sleep as possible predictors of impulsive behaviour in forensic populations. The empirical study found a relatively consistent relationship between impulsive behaviour and violent or antisocial behaviour in a sample of forensic mental health inpatients. Conclusions: The systematic review identified a limited number of risk factors thought to influence impulsive behaviour in forensic populations. The review highlights the need for future research with improved methodological design to further explore contributory factors for increased levels of impulsivity. Findings from the empirical study reveal clinician rating of impulsive behaviour to be the most sensitive in predicting future incidents of violent and antisocial behaviour, which may be supplemented by the addition of a self-report measure.

Association Between Sleep Duration During Adolescence and Violent Behavior Among Young Adults in the United States

Subedi, Pooja, Alamian, Arsham, Brooks, Billy, Alamian, Ali, Zheng, Shimin 04 November 2017 (has links)
Youth violence is a public health threat in the United States. Inadequate sleep is identified as a risk factor, however, the majority of previous studies were cross-sectional and focused only on adolescents. This study aimed to investigate the association between average hours of sleep during adolescence and violent behavior among youths. Individuals who participated in both Waves II (1996) and III (2000-2001) of National Longitudinal Study of Adolescent and Adult Health (n=3,557) were included. A composite variable on violent behavior was created using three different questions on fighting or using a weapon. Age, gender, ethnicity, violent behavior during adolescence, depressive symptoms, impulsivity, and current sleep hours were considered as covariates. Negative binomial regressions were conducted using SAS 9.4. The mean age of the participants was 15.85 years (SD=1.62) and 21.29 years (SD=1.60) in waves II and III, respectively. The majority of the participants were female (54.15%) and non-Hispanics (88.93%). Average hours of sleep during adolescence was not significantly associated with violent behavior during young adulthood (p=0.75). In the final model, gender (beta=1.65, p<0.001), age (beta=-0.1267, p<0.001), history of violent behavior (wave II) (beta=0.3158, p<0.0001), current average hours of sleep (wave III) (beta=-0.073, p=0.044), depressive symptoms (beta=0.0834, p <0.0001), and impulsivity (beta=0.1379, p<0.0001) were significantly associated with violent behavior in early adulthood. Reduced number of sleep hours during early adulthood, unlike during adolescence, increased the likelihood of getting involved in violent activities during early adulthood. This information is useful to promote healthy behavior among individuals in all phases of their life.

Parent and Teacher Perspectives of Children's Access to Violent Media

O'Neal, Sarah Michelle 01 January 2018 (has links)
Researchers indicate repeated participation in violent video games increases the likelihood of aggressive and hurtful behavior toward others. Media violence is one of the most studied phenomena affecting children over the age of 8. Media violence has become accessible for very young children through various sources. The purpose of this study was to explore perspectives of parents and teachers of children 5 to 8 years old regarding children's exposure to violent media, their definitions of violent media, and parental monitoring practices. Questionnaires were completed by 35 parents, and 6 agreed to participate in face-to-face or telephonic interviews. Four teachers from kindergarten through second grade participated in face-to-face interviews. Bronfenbrenner's model of human ecology was the conceptual framework. A combination of a priori and open coding was used to support thematic analyses. Participants indicated they need to be more informed about the possible effects that exposure to violent media, specifically video games, has on children. Both parents and teachers noted that often it was the younger children, specifically of kindergarten age, who were exposed to the most amount of time with violent media. Implications for positive social change included ways to properly monitor children's access, such as more restrictions on time and content of the media. This research could provide support to advocacy groups to provide parents, educators, and policymakers with reliable data on children's media use and the impact it has on children.

Understanding Experiences of Female Survivors of Domestic Violence: Stories of Strength, Resilience, and Mechanisms that Assist in Leaving Violent Relationships

Cordero, Annel 01 May 2014 (has links)
Domestic violence (DV) touches the lives of many individuals in close, intimate relationships. Women of all ages, ethnicities, nationalities, and from all walks of life—the poor and the wealthy—demonstrate how widespread this phenomenon is and shed light to the deleterious effects of DV to individuals and society. While current research has demonstrated that progress has been made and is moving away from blaming individuals in abusive situations, few studies have broached this topic using qualitative methodology in order to give voice to women’s stories in hopes of better understanding their lived experiences. The goal of this study was to provide a better understanding of women’s stories and of the mechanisms that assist women in leaving violent relationships by obtaining a complete picture of their relationships from beginning to end. Thus, by gaining more insight into their sources of strength, resilience, and mechanisms that
