No. of bitstreams: 1 Dissertacao.pdf: 1155101 bytes, checksum: a7ca46b9928cd6f70d77a0633513d0a1 (MD5) Previous issue date: 2004-09-02 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta pesquisa teve por objetivo investigar a representação de sujeitos homicidas a respeito da razão do crime (motivação) e acerca do crime propriamente dito (ação), tanto à época do homicídio (passado) quanto no momento atual (presente), por meio do juízo de representação da realidade (JRR) e do juízo de valor moral (JVM). A amostra compôs-se de 20 homens, entre 30 e 49 anos de idade, cumprindo pena sob regime de liberdade condicional na Vara de Execuções Penais de Vitória-ES. Realizamos entrevistas individuais, de acordo com o método clínico proposto por Piaget (1926/s.d.; 1932/1994). A partir dos dados encontrados, verificamos que, com relação: 1) às histórias de homicídio, a maior parte dos crimes ocorreu à noite, em espaço público, por arma de fogo, contra homens, conhecidos do transgressor, ambos alcoolizados; 2) à motivação para o homicídio, o JRR mais apontado, no presente e no passado, foi a agressão física sofrida, justificada no presente principalmente pelo fato de o agressor ter-se sentido humilhado e, no passado, pelo fato de ter querido vingar-se e pelas características próprias do transgressor ou da vítima; o JVM mais mencionado no passado foi o de que as razões estavam certas, devido a características dos entrevistados ou das vítimas, pelas humilhações sofridas ou pelo fato de que precisavam defender uma vida, ao passo que no presente o juízo mais citado pelos entrevistados foi o de que estavam errados os motivos, em face das conseqüências negativas do crime para eles e dos argumentos religiosos; 3) à ação do homicídio, o JRR mais citado no passado foi o de que os participantes cometeriam novamente o homicídio, pela humilhação sofrida ou pelo sentimento experienciado; e no presente mencionaram que não matariam de novo, devido às conseqüências negativas do crime, às características próprias ou da vítima e aos motivos religiosos; o JVM mais mencionado no passado foi o de que a ação seria errada, pelas conseqüências negativas, enquanto no presente todos julgaram como errado o homicídio cometido, devido às conseqüências negativas, ao valor atribuído à vida e a motivos religiosos; 4) aos dados em geral, houve uma tendência maior em condenar o homicídio e não a sua motivação; os argumentos religiosos ligaram-se ao fato de, no presente, os entrevistados julgarem como erradas a motivação e a ação do crime e, portanto, não o fariam novamente; as explicações veiculadas à humilhação pertencem principalmente ao passado, para justificar como corretos os juízos de valor das motivações e da ação, razão pela qual naquela época cometeriam novamente o homicídio, com uma ação pela honra . / The objective of this research was to investigate the representation of homicidal subjects as to the reasons of. the crime ( motivation ), and of the crime itself ( action ), not only at the time of the homicide ( past ) as for the present moment as well ( present ), by means of judgement of representation of reality (JRR), and of judgement of moral value (JVM). The sample consisted of 20 men, their ages varying between 30 and 49 years old, in prison and under parole at the Court s Division of Penal Executions of Vitória-ES. Individual interviews were made, according to the clinical method proposed by Piaget ( 1926/s.d.; 1932/1994). From the gathered data, we verifyed that in relation to: 1) the homicidal stories, most crimes took place at night, in public spaces, by fire weapon, against men known to the transgressor, both drunk; 2) as to the motivation for homicide, the JRR emphasized in the present and in the past, the physical aggression which took place, justified in the present mainly because the aggressor felt humiliated, and in the past, because he wanted to take revenge, and the transgressor s or victim s own characteristics; the JVM that was more mentionned in the past, was that their reasons were right due to the characteristics of those interviewed or of the victims, for the suffered humiliations or for the fact that they had to defend a life, whereas in the present, the most cited judgement was that their motives were wrong, in face of. the negative consequences of their crime, and of the religious arguments; 3) as to the action of the homicide, the JRR most mentionned in the past , was that those who had committed it, would do it again, either for the suffered humiliation or for the feeling they had experienced; and in the present they mentionned that they wouldn t kill again, due to the negative consequences of the crime, to the victim s own characteristics, and to religious motives; the JVM more mentionned in the past was that the action would be wrong, because of. the negative consequences, whereas in the present all of them judged as wrong the committed homicide, due to negative consequences, to the value attributed to life, and to religious motives; 4) as to the data in general , there was a greater tendency in condemning the homicide, and not its motivation; the religious arguments were linked to the fact that in the present , those interviewed judged as wrong the motivation and the action for the crime, and therefore they wouldn t do it again; the explanations linked to humiliation belongs mainly to the past, so as to justify as correct the judgement of value of the motivation and of the action, as a reason for why at that time, they would commit homicide again, as an action for honour .

No. of bitstreams: 1 Manetta_Alex_D.pdf: 2981876 bytes, checksum: 019aa85583b582456fe17d20407542ac (MD5) Previous issue date: 2013 / Resumo: Há décadas o homicídio juvenil masculino tem sido vislumbrado como um fenômeno em expansão no Brasil. A demografia, como campo por excelência dos estudos da população, contribui nesse debate não somente através do reconhecimento das unidades espaciais, dos períodos e dos segmentos da população particularmente afetados por esse tipo específico de violência. Partindo das concepções teóricas que associaram - em décadas passadas - o processo de transição da estrutura etária ao agravo nas condições de ocupação laboral e às tendências de elevação das taxas de homicídio para a população juvenil masculina, procura-se avaliar se o momento atual da dinâmica sócio-demográfica poderia ainda hoje estar potencializando contextos propícios à disseminação de formas não convencionais de inserção socioeconômica, o que inclui a integração de homens jovens na criminalidade urbana violenta. A diversidade de fatores reconhecidos no debate atual sobre a expansão da criminalidade e da violência juvenil homicida no Brasil sugeriu uma análise multiescalar através da qual a população juvenil masculina e os sub-espaços urbanos relativamente desassistidos pelo poder público estariam servindo como recursos úteis à expansão de economias transnacionais do ilícito. Dentro dessa perspectiva vislumbra-se a disseminação da violência letal entre homens jovens em Brasília (DF)/Entorno de Brasília (GO) como manifestação essencialmente ligada à disseminação de oportunidades de reprodução social e econômica através da integração à circuitos transnacionais do crime, visto que a elevação recente (2000/2010) das taxas de homicídio juvenil masculino não corresponde aos períodos caracterizados pelo crescimento proporcional e absoluto da população jovem e nem mesmo pelo agravo nas condições de ocupação laboral formal e remunerada. Com o intuito de melhor vislumbrar a relevância dos aspectos sócio-demográficos nesse processo, utiliza-se uma contraposição entre as dinâmicas recentemente observadas em Brasília/Entorno de Brasília e em Parecis/Alto Teles Pires (MT), sub-região mato-grossense marcada pelo crescimento absoluto e proporcional da população de homens jovens, onde o homicídio juvenil masculino não aparece como tendência contemporânea predominante / Abstract: For decades the male juvenile homicide has been envisioned as a booming phenomenon in Brazil. The demography, as a field of study par excellence of the population, contributes to this debate not only through recognition of spatial units, periods and segments of the population particularly affected by this particular type of violence. Based on the theoretical concepts associated with that - in past decades - the transition in age structure to the offense in terms of occupation and employment trends of rising homicide rates for young male population, attempts to assess whether the current time dynamics socio-demographic could still be leveraging contexts conducive to the spread of unconventional ways of socioeconomic status, which includes the integration of young men in violent urban crime. A variety of factors recognized in the current debate over the expansion of crime and youth violence homicide in Brazil suggested a multiscale analysis whereby the male youth population and sub-urban areas relatively underserved by the government would serve as useful resources for expansion transnational illicit economies. Within this perspective glimpses the spread of lethal violence among young men in Brasília (DF)/Entorno de Brasília (GO) as a manifestation essentially linked to the spread of opportunities for social and economic reproduction through integrating the circuits transnational crime, since the recent high (2000/2010) of male juvenile homicide rates does not correspond to periods characterized by absolute and proportional growth of the youth population and even by worsening conditions in formal employment and gainful occupation. In order to better discern the relevance of socio-demographic aspects in this process uses up a contrast between the dynamics recently observed in Brasilia/Entorno de Brasilia and Parecis/Alto Teles Pires (MT), sub-region of Mato Grosso marked by the absolute and proportional growth of the young men population, where the male juvenile homicide does not appear as an dominant contemporary trend / Doutorado / Demografia / Doutor em Demografia

Crimes of passion : homicide in intimate relationships : a Public Health-Bulhanian perspective

Williamson, Gerald 04 September 2012 (has links)
M.A. / A sample population of nine men arrested in Johannesburg, for killing their female partners (former spouse or girlfriend) is analyzed in the context of their killings. The analysis approaches homicide as a Public Health problem and a preventable phenomenon. The analysis proceeds from Public Health and Bulhanian theoretical perspectives. These theories emphasize the relationship and interplay between the social, political, psychological and economic environments and the overall effect they have on individual processes. By contextualising the homicide event into pre-event, event and post-event categories, the study is able to identify risk factors which played a role in the homicide act. The tool of analysis employed in the service of this study is called the Haddon Matrix and is widely used in the Public Health domain as a means of identifying and considering, section by section, the risk factors associated with the injury, the relevant research and other knowledge available and what is needed for the future and the priorities for countermeasures. Analysis includes demographic and social characteristics of the perpetrator and the incident. The results indicate problems in education, communication and the concept of the nuclear family. In the Public Health-Bulhanian sense, the results indicate that the homicide incident originates and occurs within the context of the prevailing conditions of social structural constraint, in the experienced psychological strain of individuals and in the prevailing threshold of social tolerance. The lack of basic human needs, such as professional help, for example, is an indication of the impact that the cumulative effect of social structural constraint has on the family's health. The study also found that individuals experience trauma and pain in a context where objective social conditions affect the rights and privileges of individuals and there is a strain being created on the subjective world of perception, feeling and meaning. It is this wealth of information on the trauma points which presents opportunities for prevention. Among the proposed areas for interventions are: Change individual knowledge, skills or attitudes, such as conflict resolution education, for example. Change social environments, such as better housing, economic incentives for family stability and counselling centres. Change physical environments and agents of violence, such as the availability of dangerous weapons and the increased policing of high risk areas, for example. In conclusion, the study aspires to enrich existing debate in the area of homicide as a Public Health issue.

Psychoanalytical approach to serial killers

Pistorius, Micki January 1996 (has links)
The phenomenon of serial killers is increasing world wide. During the past decade the most memorable cases of serial homicide in South Africa have been those of the "Norwood serial killer", the "Station Strangler", the "Cleveland serial killer", "The Gaunteng serial killer" and the "St Charles serial killer". The enigma surrounding serial killers is the so-called "lack of motive'' for the murders. No extrinsic motive such as robbery, financial gain, revenge or passion exists as there usually would be in the case of other murders. The available literature indicates that several theories have been proposed to explain the origin of serial homicide, but none can explain sufficiently to the author why one person with a certain type of background and exposed to a certain environment becomes a serial killer, whilst another, with a similar background and circumstances does not. The theories that are discussed are the socio-cultural factors, Ressler's motivational model, systemic factors, demonic possession, neurological factors, psychogenic factors and fantasy. In this thesis the author attempts to answer the question "What is the origin of serial homicide" by applying selected aspects of the psychoanalytic theories of Freud and Melanie Klein on two case studies of South African serial killers. The author formulates twenty nine statements of her own, based on the theories of Freud and Klein which she applies to the two case studies. The cases of the "Station Strangler" in Mitchell's Plain, Cape province, and the "St Charles serial killer" in Donnybrook, KwaZulu Natal are selected. Both of these serial killers are organized in their modus operandi, but the "Station Strangler" is a ego-dystonic killer and the "St Charles serial killer" a ego-syntonic serial killer. The method of research is a qualitative case study method. The author divides the selected aspects of Freud and Klein's theories into categories and analyses the two cases presented according to these categories. In the final chapter she draws maps to illustrate the psychoanalytical developmental paths of serial killers in general and for each of the two cases. Multiple data sources are used for example interviews with the serial killers and their families, police dockets, court proceedings and psychiatric records. Multiple data sources, explanation building and replication by way of multiple case studies are employed to ensure construct validity, internal validity and external validity respectively. Reliability is supported by entering the data in a South African Police Service data base. In conclusion the author compares the differences and similarities between the two case studies, and discusses the statements which are supported by this research. She also recommends that those statements which are not supported, be discussed in consecutive case studies. The statements are generalized to all serial killers. / Thesis (PhD)--University of Pretoria, 1996. / gm2013 / Psychology / unrestricted

家庭內殺人案件量刑中被害人因素之探討 / The Study about Factor of Victim in Sentencing on Domestic Homicide Cases

連珮君 Unknown Date (has links)
依家庭暴力防治法規定,家庭內殺人案件不論是因為不堪家庭暴力殺夫,或是出於忌妒憤而殺妻,抑或是不滿叨唸而砍殺父母,不僅係為家庭暴力事件,亦屬發生於家庭成員間最嚴重之暴力犯罪事件。在家庭暴力事件層面,不乏從家庭暴力加害人、被害人或兩造互動關係等觀點,探討家庭暴力加害人實施或家庭暴力被害人身處家庭暴力環境之原因,然以家庭暴力刑事案件層面,則聚焦於刑事司法如何評價犯罪行為人殺害家庭成員之行為,特別是兩造間具有親屬關係、犯罪動機與被害人之行為具有密切關連,或是犯罪行為人犯罪行為時受有被害人挑撥或刺激等。 惟據衛生福利部針對家庭暴力事件通報總數,法務部對於家庭暴力刑事案件新收案件、起訴率之計算,以及司法院關於家庭暴力刑事案件裁判結果等統計數據,尚無法有助於掌握我國家庭內殺人案件發生情形或犯罪情狀,是本文透過整理我國90年至104年之實務判決,以發現我國家庭內故意殺人案件之被害人參與或促發的成分,透過整理歸納家庭內殺人案件存在之被害人刺激因素之行為型態,分析現行法院面對或評價犯罪行為中之被害人刺激因素有待檢討或釐清之處,進而借鏡外國立法例關於被害人激怒抗辯規定、學說文獻對於被害人激怒抗辯部分免責理論基礎之探討,輔以外國法實務判決適用被害人激怒抗辯情形之觀察,以求立證家庭內殺人案件中關於被害人刺激因素應有利於犯罪行為人量刑。 / According to the Domestic Violence Prevention Act, the domestic murder cases, whether or not because of unacceptable domestic violence or jealousy to kill his or her spouse, or dissatisfaction with the slaughter of parents, not only for domestic violence, also occurred in the most serious violent crime among family members. Aspect of domestic violence, many scholar pay attention about the injurers of domestic violence, or the victims of domestic violence, or the interaction of the injurers and victims of domestic violence. On the other hands, the criminal justice system concerned about the behavior of defendants who kill family members, especially those who have a kinship relationship, the motive of the crime is closely related to the victim's behavior, or the defendants provoked or stimulated by the victims. Based on Government agencies publish statistical data, it still can not help master about domstic homicide cases or crime situation in our country. In order to find the factors of victims in sentence, so that we try to search the judgment of domstic homicide cases upon 1991 to 2015, and figure out the short of these judgment about the evaluation of the victims’ behavior. Further more, through the foreign legislation on the defense of provocation, and the theory about the reason of the excuse of partial defense, and the application of the defense of provocation,it could be proved that the defense of provocation from victims in domestic homicide cases should be conducive to defendants’sentencing.

A psychosocial perspective on the personality development of the serial murderer

De Wet, Johan Andrew 05 October 2005 (has links)
The phenomenon of serial murder is a crime characterised by a paucity of scientific information and an excess of popularised fictional material, contributing to the existence of inaccurate perceptions of serial murder. Although serial murder has been committed since the fourteenth century it only gained notoriety with the intense media coverage of the Jack the Ripper case in 1888. One of the most important reasons for society’s morbid fascination with this phenomenon is because of the view of it as a “motiveless crime”. Available literature shows that research undertaken to determine the origin and the motivation behind serial homicide generally focuses on singular aspects of serial murder. In most cases the research is directed by theories of the psychoanalytic school, most notably that of Sigmund Freud. Another research approach is to develop models and methods for classifying serial killers. Despite the value of these models and the research that has been done the information they can provide is limited. In most cases the research and the models focus on singular aspects associated with the development of serial murderers, for example, the internal conflicts experienced by the child. The goal of this study is to determine which internal and external factors influence the personality development of the serial murderer. The research therefore focuses on how these factors were internalised and expressed behaviourally by the individual. To achieve this the psychosocial perspective, which consisted of three psychological theories, was used to determine the role of both internal and external influences in the personality development of the individual. The method of research deemed most suitable to undertake the study is the qualitative approach, and more specifically the explanatory case study method. The data for the research was obtained by using a semi-structured interview and relevant documentation concerning each of the two case studies. Seven research questions were formulated to find answers to the personality development of the serial murderer and his behaviour. The questions were also formulated to ensure the validity of the data and to substantiate the findings based on the psychosocial perspective. The psychosocial perspective was used to analyse the two case studies and to compile a detailed explanation for the personality development and the personality structure of each of the serial murderers. The three psychological theories were combined in such a way that it could show the influence of internal and external factors on the personality development. This included the influence of the family atmosphere as well as behaviour and personality types that developed. In conclusion the extent to which answers were obtained regarding the seven research questions and the extent to which the aim of the research has been achieved is highlighted. Finally recommendations are made concerning future research and possible areas on which researchers should focus. / Dissertation (MA (Psychology))--University of Pretoria, 2006. / Psychology / unrestricted

Cityscape, poverty and crime: a quantitative assessment using VHR imagery

Patiño Quinchía, Jorge Eduardo 07 January 2016 (has links)
[EN] The first part of this work reviews the potential applications of satellite remote sensing to regional science research in urban settings. The availability of satellite remote sensing data has increased significantly in the last two decades. The increasing spatial resolution of commercial satellite imagery has influenced the emergence of new research and applications of regional science in urban settlements because it is now possible to identify individual objects of the urban fabric. The most common applications found in the literature are the detection of urban deprivation hot spots, quality of life index assessment, urban growth analysis, house value estimation, urban population estimation, urban social vulnerability assessment, and the variability of intra-urban crime rates. The satellite remote sensing imagery used in these applications has medium, high or very high spatial resolution (Landsat MSS, Landsat TM and ETM+, SPOT, ASTER, IRS, Ikonos and QuickBird). Consistent relationships between socio-economic variables derived from censuses and field surveys and proxy variables of vegetation coverage measured from satellite remote sensing data have been found in several cities in the US. Different approaches and techniques have been applied successfully around the world, but local research is always needed to account for the unique elements of each place. Spectral mixture analysis, object-oriented classifications and image texture measures are some of the techniques of image processing that have been implemented with good results. This work contributes empirical evidence about the usefulness of remote sensing imagery to quantify the degree of poverty at the intra-urban scale. This concept is based on two premises: first, that the physical appearance of an urban settlement is a reflection of the society; and second, that the people who reside in urban areas with similar physical housing conditions have similar social and demo- graphic characteristics. We evaluate the potential of the image-derived urban fabric descriptors to explain a measure of poverty known as the Slum Index. We found that these variables explain up to 59% of the variability in the Slum Index. Similar approaches could be used to lower the cost of socioeconomic surveys by developing an econometric model from a sample and applying that model to the rest of the city and to perform intercensal or intersurvey estimates of intra-urban Slum Index maps. The last part of this work analyzes the relation between the urban layout and crime. The link between place and crime is at the base of social ecology theories of crime that focus in the relationship of the characteristics of geographical areas and crime rates. The broken windows theory states that visible cues of physical and social disorder in a neighborhood can lead to an increase in more serious crime. Based on the premise that a settlement's appearance is a reflection of the society, we ask whether a neighbor- hood's design has a quantifiable imprint when seen from space using urban fabric descriptors computed from VHR imagery. The percentage of impervious surfaces other than clay roofs, the fraction of clay roofs to impervious surfaces, two structure descriptors related to the homogeneity of the urban layout, and the uniformity texture descriptor were all statistically significant. Areas with higher homicide rates tended to have higher local variation and less general homogeneity; that is, the urban layouts were more crowded and cluttered, with small dwellings with different roofing materials located in close proximity to one another, and these regions often lacked other homogeneous surfaces such as open green spaces, wide roads, or large facilities. These results seem to be in agreement with the broken windows theory and CPTED in the sense that more heterogeneous and disordered urban layouts are associated with higher homicide rates. / [ES] La primera parte aporta una revisión de las aplicaciones de la teledetección satelital en la investigación de ciencia regional en entornos urbanos. La disponibilidad de imágenes satelitales se ha incrementado significativamente en las dos últimas décadas, al tiempo que la resolución espacial ha venido aumentando, lo que ha influenciado el surgimiento de investigaciones y aplicaciones de ciencia regional en zonas urbanas. Las aplicaciones más comunes son la detección de hot spots de pobreza urbana, la evaluación de índices de calidad de vida, el análisis del crecimiento urbano, la estimación de valores de vivienda, la estimación de población urbana, la evaluación de la vulnerabilidad social y las variaciones intra-urbanas en tasas de crimen. Las imágenes satelitales usadas tienen resolución espacial media, alta o muy alta (Landsat MSS, Landsat TM y ETM+, SPOT, ASTER, IRS, Ikonos y Quickbird). Se han encontrado relaciones consistentes entre variables socio-económicas obtenidas de censos y encuestas y variables de la cobertura de vegetación en varias ciudades de Estados Unidos. Algunas de las técnicas que se han implementado y obtenido buenos resultados son el análisis de mezcla espectral, las clasificaciones orientadas a objetos y las medidas de textura de la imagen. Se aporta evidencia empírica acerca de la utilidad de las imágenes satelitales para cuantificar el grado de pobreza a escala intra-urbana. Se basa en dos premisas: primero, que la apariencia física de un asentamiento urbano es un reflejo de la sociedad que lo habita; y segundo, que la población de áreas urbanas con condiciones físicas de vivienda parecidas tiene características sociales y demográficas similares. Evaluamos el potencial de los descriptores del tejido urbano extraídos de la imagen para explicar una medida de pobreza conocida como el índice Slum. Encontramos que esas variables explican hasta un 59% de la variabilidad en el índice Slum. Aproximaciones similares a esta podrían usarse para disminuir el costo de encuestas socioeconómicas por medio del desarrollo de un modelo econométrico usando una muestra y luego aplicando el modelo al resto de la ciudad, y para elaborar estimaciones inter-censales o inter-encuestas de mapas intra-urbanos del índice Slum. La última parte analiza la relación entre el trazado urbano y crimen. El enlace entre el lugar y el crimen está en la base de las teorías socio-ecológicas de crimen que se enfocan en la relación de las características de las áreas geográficas y las tasas de crimen. La teoría de las ventanas rotas afirma que las evidencias visibles de desorden físico y social en un barrio pueden llevar al incremento de crímenes más serios. Con base en la premisa de que la apariencia de un asentamiento es un reflejo de la sociedad, nos preguntamos si el diseño del barrio tiene un impacto cuantificable cuando se observa desde el espacio usando descriptores del tejido urbano obtenidos de imágenes de muy alta resolución. El porcentaje de superficies impermeables diferentes a los techos de arcilla, la fracción de techos de arcilla sobre las superficies impermeables, dos variables de estructura relacionadas con la homogeneidad del trazado urbano y la variable de textura uniformidad resultaron estadísticamente significativas. Las áreas con tasas de homicidio más altas tienden a tener mayor variación local y menor homogeneidad general; esto es, los trazados urbanos son más desordenados y hacinados, con pequeñas viviendas que tienen materiales diferentes en sus techos localizadas muy cerca unas de otras, y estas áreas carecen a menudo de otras superficies homogéneas tales como espacios verdes abiertos, vías amplias y grandes construcciones industriales o institucionales. Estos resultados parecen estar en acuerdo con la teoría de las ventanas rotas y CPTED en el sentido de que los trazados urbanos más desordenados y heterogéneos están asociados con tasas de homicid / [CAT] La primera part aporta una revisió de les potencials aplicacions de la teledetecció espacial a la investigació en ciència regional en entorns urbans. La disponibilitat de dades de percepció remota des de satèl·lits s'ha incrementat significativament a les dues últimes dècades. La resolució espacial de les imatges de satèl·lit comercials també han anat augmentant i això, ha influït en l'aparició de investigacions i aplicacions a la ciència regional en assentaments urbans. Les aplicacions més comunes trobades a la literatura són la detecció de punts calents de pobresa urbana, l'avaluació dels índex de qualitat de vida, les anàlisis de creixement urbà, l'avaluació de la vulnerabilitat social i les variacions intraurbanes de les taxes de crims. Les imatges de satèl·lit emprades tenen resolució espacial mitjana, alta o molt alta (Landsat MSS, Landsat TM i ETM+, SPOT, ASTER, IRS, Ikonos y Quickbird). S'han torbat relacions consistents entre variables socioeconòmiques obtingudes de censos i enquestes i variables de la cobertura de vegetació en varies ciutats del Estats Units. Algunes de les tècniques que s'han implementat i han donat bons resultats són l'anàlisi de mescla espectral, les classificacions orientades a objecte i les mesures de textura de les imatges. Es aporta evidència empírica sobre la utilitat de les imatges de satèl·lit per quantificar el grau de pobresa a escala intraurbana. Es bassa en dues premisses: primer, que l'aparença física d'un assentament urbà n'és un reflex de la societat que l'habita; i segon, que les persones que resideixen en àrees urbanes amb condicions físiques de vivenda paregudes tenen també característiques socials i demogràfiques similars. Avaluem el potencial dels descriptors del teixit urbà extrets de la imatge per explicar una mesura de pobresa coneguda com index Slum. Trobem que aquestes variables expliquen fins un 59% de la variabilitat de l'índex Slum. Aproximacions semblants a aquesta es podrien emprar per a disminuir el cost de les enquestes socioeconòmiques mitjançant el desenvolupament d'un model economètric utilitzant una mostra i després aplicant el model a la resta de la ciutat, i per elaborar estimacions inter-censals o inter-enquestes de mapes intraurbans de l'índex Slum. La darrera part analitza la relació entre el traçat urbà i el crim. L'enllaç entre el lloc i el crim està a la base de les teories socio-ecològiques del crim que es centren en la relació de les característiques de les àrees geogràfiques i les taxes de crims. La teoria de les finestres trencades afirma que les evidències visibles de desordre físic i social d'un barri pot portar a l'augment de crims més greus. Basant-se en la premissa de que l'aparença d'un assentament n'és el reflex de la societat, ens hi preguntem si el disseny del barri té un impacte quantificable quan s'observa des de el espai, utilitzant descriptors del teixit urbà obtinguts de imatges de molt alta resolució. Han resultat estadísticament significatius el percentatge de superfícies impermeables diferents a les teulades de argila, la fracció de teulades d'argila sobre les superfícies impermeables, dues variables d'estructura relacionades amb la homogeneïtat del traçat urbà i la variable de textura de uniformitat. Les àrees amb taxes d'homicidi més altes tendeixen a presentar una major variació local i una menor homogeneïtat general; és a dir, el traçats urbans són més desordenats i amuntonats, amb petites vivendes que tenen materials diferents a les seues teulades localitzades molt prop unes d'altres, i aquestes àrees manquen sovint d'altres superfícies homogènies, com ara espais verds oberts, vies amplies i grans construccions industrials o institucionals. Aquests resultats pareixen estar-hi d'acord amb la teoria de les finestres trencades i CPTED en el sentit de que els traçats urbans més desordenats i heterogenis estan associats amb taxes d'homicides m / Patiño Quinchía, JE.

Indiana University-Purdue University Indianapolis (IUPUI) / Increasing rates of social harm events and plethora of text data demands the need of employing text mining techniques not only to better understand their causes but also to develop optimal prevention strategies. In this work, we study three social harm issues: crime topic models, transitions into drug addiction and homicide investigation chronologies. Topic modeling for the categorization and analysis of crime report text allows for more nuanced categories of crime compared to official UCR categorizations. This study has important implications in hotspot policing. We investigate the extent to which topic models that improve coherence lead to higher levels of crime concentration. We further explore the transitions into drug addiction using Reddit data. We proposed a prediction model to classify the users’ transition from casual drug discussion forum to recovery drug discussion forum and the likelihood of such transitions. Through this study we offer insights into modern drug culture and provide tools with potential applications in combating opioid crises. Lastly, we present a knowledge graph based framework for homicide investigation chronologies that may aid investigators in analyzing homicide case data and also allow for post hoc analysis of key features that determine whether a homicide is ultimately solved. For this purpose we perform named entity recognition to determine witnesses, detectives and suspects from chronology, use keyword expansion to identify various evidence types and finally link these entities and evidence to construct a homicide investigation knowledge graph. We compare the performance over several choice of methodologies for these sub-tasks and analyze the association between network statistics of knowledge graph and homicide solvability.

Kvinnor som dödar sin partner. Orsaker och gemensamma nämnare

Larsson, Martin January 2016 (has links)
Kvinnor begår färre våldsbrott än män, och endast en tiondel av alla mord begås av kvinnor. Detta speglas i att relativt lite forskning om kvinnor som begår dödligt våld har genomförts. När kvinnor dödar är det ofta en nuvarande, eller före detta, intim partner som faller offer. Men varför dödar kvinnor en person som de tidigare valt att spendera sitt liv med? Finns det några likheter mellan dessa kvinnor? Denna systematiska litteraturstudie visar att en majoritet av de kvinnor som tar livet av sin partner, gör det efter att ha utsatts för fysiskt och psykiskt våld av sin partner under lång tid. Tidigare partnervåld, och den överhängande risken att utsättas för ännu en episod av grovt våld, leder till att dessa kvinnor lever med ständig skräck, rädsla och ångest. Många av dessa kvinnor upplever även en känsla av isolation, vilket förstärks av att mannen ofta förbjuder dem att arbeta utanför hemmet. Kvinnor som dödar sin partner gör det ofta i, vad de själva anser är, självförsvar. Många av dessa kvinnor menar att de dödade sin partner för att de var tvungna. Hade de inte gjort det hade de själva förmodligen blivit mördade. / Women commit fewer violent crimes than men, with only one tenth of all murders committed by females. This is reflected in the fact that relatively little research has been conducted about women who kill. When women kill, the victim is often a current or former intimate partner. But why do some women kill an individual whom they have previously chosen to spend their life with? Are there any similarities between these women? This systematic literature review shows that a majority of women who take the life of an intimate partner, do it after having been subjected to physical and psychological violence by their partner for a long period of time. Former partner violence, and the imminent risk of being subjected to yet another episode of serious violence, leads to these women living with constant fear, horror and anxiety. Many of these women also experience a sense of isolation, which is reinforced by the fact they their partner often forbids them to work outside of the home. Women who kill their intimate partner often do so in, what they feel is, self-defence. Many of these women say that they killed their partner because they had to. Had they not killed him, they themselves would probably have been murdered.
