A model of rural conflict : violence and land reform policy in Brazil

In the past ten years the struggle for land in Brazil has taken the shape of invasions of private land by welI organized groups of land less squatters. It is argued in this paper that these invasions and the resulting contlicts are a direct response to the land reform program which has been adopted by the govemment since 1985. which is based on the expropriation of farms and the creation of settlement projects. The set of formal and informal institutions which compromise the land reform program are used as the background for a game-theory model of rural contlicts. T estable implications are derived trom this model with particular emphasis on the etfect of policy variables on violence. These are then tested with panel data at state levei from 1988 to 1995. - It is shown that govemment policy which has the intent of reducing the amount of violence has the opposite etfect of leading to more incentives for contlicts.

The United Nations Regional Commissions: Enhancing Capacities To Eradicate Violence Against Women

This study captures the significant regional and national knowledge that has been accumulated on measuring violence against women through the interregional project "Enhancing capacities to eradicate violence against women through networking of local knowledge communities". Supported by the United Nations Development Account, this two-year project was coordinated by the Economic Commission for Latin America and the Caribbean (ECLAC), through its Division for Gender Affairs, and implemented by the five regional commissions of the United Nations, in cooperation with the United Nations Statistical Division and UN-Women. Through the project, more than 30 countries worldwide have been engaged in the development, dissemination and testing of core indicators endorsed by the United Nations Statistical Commission. This process has made a decisive contribution to designing and building consensus around a common methodology to measure and document violence against women. Furthermore, the inclusion of all five regions in piloting the newly-developed tools to measure violence has also ensured that these tools capture a more comprehensive and complex vision of violence as experienced by women across cultures and regions. This report presents an overview of the activities that have taken place in the five regions, and outlines the key outcomes and lessons learned. Through its activities, the interregional project has made the cumulative body of existing knowledge in terms of policies, findings, innovative practices, processes and statistical data available to policymakers, activists and women's organizations. New knowledge was also produced through national studies that examined underexplored sources of data on violence against women. National capacities to collect information on violence against women through official statistics were strengthened through targeted training activities as well as through participation in expert meetings which provided the space for an effective exchange of best practices.

Eliminating gender-based violence ensuring equality: ECLAC/UNIFEM assessment of actions

This study represents a collaborative effort by the Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean and the United Nations Development Fund for Women (UNIFEM) to assess these actions with the aim of informing the future work of these agencies around gender-based violence. An important dimension of the mandate of the ECLAC Subregional Headquarters for the Caribbean is the provision of strategic thinking and information to governments for policy formulation. This is accomplished through technical assistance and through research activities. At the Third Economic Commission for Latin America and the Caribbean/Caribbean Development and Cooperation Committee (ECLAC/CDCC) Ministerial Conference on Women held in October 1999, violence against women was identified as a barrier to achieving gender equality. The recommendations spoke not only of the need to extend services to victims, but also to take actions based on an understanding of the root causes of violence. This study forms one component in a scope of work in which the ECLAC Subregional Headquarters for the Caribbean has been engaged since 1999.

Violence against children and adolescents: awareness and attitudes of Brazilian dentists

Violence against children and adolescents, ranging from negligence to sexual abuse, is an imperative public health problem. The ill treatments are considered as nonaccidental traumas, actions or omissions against children, who suffer physical or emotional violence. The main perpetrators are fathers, mothers, guardians, family, friends or the children‘s primary caretaker. It is very important to identify abuse cases, because this allows proper medical and legal intervention. In Brazil, the law n. 8.069, of July 13, 1990, known as the ECA -Statute for Children and Adolescents (SCA), stipulates the obligation to report suspected or confirmed cases of ill treatment against a child or adolescent to the Guardianship Council of the respective locality. The health professionals play a crucial role with regard to identifying cases of violence, collecting information, making early diagnosis of suspect cases and reporting such cases to the authorities. The dentists can contribute significantly, as most injuries occur in the orofacial region. Bite marks, burns, bruising, among others, are easily identified during a dental consultation. The aim of this work was to verify the awareness and attitudes of Brazilian dentists concerning violence against children and adolescents. This research was approved by the Research Ethics Committee of the Faculty of Dentistry of Araraquara – São Paulo State University (FOAr – UNESP). Sixty-three dentists answered an open and closed questionnaire concerning their formation, knowledge, experience and attitudes towards ill-treated children and adolescents. Among other results, thirty-nine dentists (61.9%) affirmed to have the means to identify illtreatment cases, 13 (20.6%) reported having some experience on this matter, but only 8 reported the cases to the Council of Guardianship, as determined by Brazilian law. Twenty percent of the reasons presented for not notifying the Council were fear of reprisal, and 60.0% were uncertain concerning the ethical and legal implications. Physical violence was the most reported form of identified violence (76.9%), followed by negligence (38.5%). Among the 13 professionals that had experience with violence cases, in 10 cases the perpetrators were identified – in 70.0% of the cases, the parents were the originators of such violence. It was concluded that further formation and orientation are necessary, in order to prepare dentists to act correctly when, during their professional activities, they encounter cases of violence against children and adolescents.

Violence against children and adolescents: the importance of knowledge of the spectrum of bruise colors in its diagnosis

Introduction: One of the violence types more observed against children is the physical abuse, which produces many types of traumatic injuries. Contusions are common trauma signs and may indicate aggression when frequently present in locations where accidental injuries are rare. Contusions in skin undergo color changes with the passage of time, and such change in color is called “spectrum of bruise colors of Legrand du Saulle”. Thus, it is possible to estimate the age of the lesion based on the evaluation of color. Injuries caused by child abuse often reach regions of head, face and neck, because they are exposed and easily accessible. Therefore, the dentist is responsible with regard to the diagnosis and the actions to be undertaken against the cases of child abuse. Objective: To present and discuss the significance of the spectrum of bruise colors as a considerable visible trace in suspicion of violence against children and adolescents, during dentists’ clinical routine. Literature review: The study of the “spectrum of bruise colors of Legrand du Saulle” refers to the estimation of the age of the injury, in respect to the color change. The application of this study is of great value for identify if a lesion occurred from a single incident or from multiple incidents, especially in cases where it occurs in the same region of the body, indicative of repetitive trauma. Conclusion: The spectrum of bruise colors is very important for health professionals, such as dentists, for the identification or suspicion of cases of abuse against children and adolescents. As great part of the lesions originated of abuse involve the areas of head and neck, it is unacceptable that these professionals are unaware of the basic signs to help in early diagnosis, which is the case of the colors of the lesions. However, concerning the chronology of the spectrum of bruise colors, it is not possible to establish rigorous times.

Construction and validation of an instrument that breaks the silence: the impact of domestic and/or sexual violence on women's health, as shown during climacterium

Objective: The aim of this study was to construct and to validate a measure of the consequences of domestic violence on women's health during climacterium. Methods: A questionnaire was administered at the Outpatient Climacterium Clinic to 124 women aged 40 to 65 years who were the victims of domestic and/or sexual violence (experimental group). They were divided into three groups: (1) those who were victims of violence exclusively during childhood/adolescence, (2) those who were victims of violence exclusively during adulthood, and (3) those who were victims of violence throughout their lives. The instrument included 34 items evaluating the beginning, frequency, and type of violence; the search for health assistance and reporting of the violence; the violence and the number of comorbidities; and violence and the Kupperman Menopausal Index. We also included a control group composed of perimenopausal and postmenopausal women who did not experience any violence (n = 120). Results: The instrument presented a Cronbach alpha = 0.82, good reliability among the examiners (+0.80), and a good possibility of reproducibility. The mean age of menopause was 45.4 years, and the mean age in the control group was 48.1 years. Group 1 showed a mean of 5.1 comorbidities, Group 2 had 4.6, and Group 3 had 4.4. Sexual violence (43.5%) and other types of violence both presented average comorbidities (4.60) but represented a significant impairment in the victim's sexual life. There were significant associations in group 3 and a high Kupperman Menopausal Index score. In the experimental group, 80.6% did not seek health services for the violence they experienced. Conclusions: The questionnaire presented good internal consistency and a validated construction. It can be easily reproduced and is indicated to evaluate the consequences of domestic and/or sexual violence on women's health during climacterium.

Police Interviews with Victims and Suspects of Violent and Sexual Crimes : Interviewee's experiences and interview outcomes

The police interview is one of the most important investigative tools that law enforcement has close at hand, and police interview methods have changed during the twentieth century. A good police interview is conducted in the frame of the law, is governed by the interview goal, and is influenced by facilitating factors that may affect the elicited report. The present doctoral dissertation focuses on police interviews in cases of very serious crimes of violence and sexual offences. Results reveal crime victims’ and perpetrators’ experiences of being interviewed and police officers’ attitudes towards conducting interviews related to traumatizing crimes. Study 1 revealed that when police officers interviewed murderers and sexual offenders, the interviewees perceived attitudes characterized by either dominance or humanity. Police interviews marked by dominance and suspects’ responses of anxiety were mainly associated with a higher proportion of denials, whereas an approach marked by humanity, and responses of being respected were significantly associated with admissions. In line with Study 1, the victims of rape and aggravated assault in Study 2 also revealed the experience of two police interview styles, where an interviewing style marked by dominance and responses of anxiety was significantly associated with crime victims’ omissions of information. Moreover, a humanitarian interviewing style, and crime victims’ feelings of being respected and co-operative, was significantly related to crime victims providing all information from painful events. Special squad police officers’ attitudes towards interviewing crime victims, in Study 3, also showed a humanitarian approach and two dominant approaches, one affective and the other refusing. The attitude towards interviewing suspects of crimes in focus revealed humanitarian and dominant interviewing attitudes, and an approach marked by kindness. The present thesis shows that, during their entire career, an overwhelming majority of the special squad police officers have experienced stressful events during patrol as well as investigative duty. Results show that symptoms from stressful event exposures and coping mechanisms are associated with negative attitudes towards interviewing suspects and supportive attitudes towards crime victim interviews. Thus, experiences from stressful exposures may automatically activate ego-defensive functions that automatically generate dominant attitudes. Moreover, it is important to offer police officers who have been exposed to stressful events the opportunity to work through their experiences, for example, through debriefing procedures. After debriefings, police officers are better prepared to meet crime victims and suspects and, through conscious closed-loop processes, to conduct police interviews without awaking ego-defensive functions.

Numerical simulations of microphysical processes in pyro-convective clouds

Hochreichende Konvektion über Waldbränden ist eine der intensivsten Formen von atmosphärischer Konvektion. Die extreme Wolkendynamik mit hohen vertikalen Windgeschwindigkeiten (bis 20 m/s) bereits an der Wolkenbasis, hohen Wasserdampfübersättigungen (bis 1%) und die durch das Feuer hohen Anzahlkonzentration von Aerosolpartikeln (bis 100000 cm^-3) bilden einen besonderen Rahmen für Aerosol-Wolken Wechselwirkungen.Ein entscheidender Schritt in der mikrophysikalischen Entwicklung einer konvektiven Wolke ist die Aktivierung von Aerosolpartikeln zu Wolkentropfen. Dieser Aktivierungsprozess bestimmt die anfängliche Anzahl und Größe der Wolkentropfen und kann daher die Entwicklung einer konvektiven Wolke und deren Niederschlagsbildung beeinflussen. Die wichtigsten Faktoren, welche die anfängliche Anzahl und Größe der Wolkentropfen bestimmen, sind die Größe und Hygroskopizität der an der Wolkenbasis verfügbaren Aerosolpartikel sowie die vertikale Windgeschwindigkeit. Um den Einfluss dieser Faktoren unter pyro-konvektiven Bedingungen zu untersuchen, wurden numerische Simulationen mit Hilfe eines Wolkenpaketmodells mit detaillierter spektraler Beschreibung der Wolkenmikrophysik durchgeführt. Diese Ergebnisse können in drei unterschiedliche Bereiche abhängig vom Verhältnis zwischen vertikaler Windgeschwindigkeit und Aerosolanzahlkonzentration (w/NCN) eingeteilt werden: (1) ein durch die Aerosolkonzentration limitierter Bereich (hohes w/NCN), (2) ein durch die vertikale Windgeschwindigkeit limitierter Bereich (niedriges w/NCN) und (3) ein Übergangsbereich (mittleres w/NCN). Die Ergebnisse zeigen, dass die Variabilität der anfänglichen Anzahlkonzentration der Wolkentropfen in (pyro-) konvektiven Wolken hauptsächlich durch die Variabilität der vertikalen Windgeschwindigkeit und der Aerosolkonzentration bestimmt wird. rnUm die mikrophysikalischen Prozesse innerhalb der rauchigen Aufwindregion einer pyrokonvektiven Wolke mit einer detaillierten spektralen Mikrophysik zu untersuchen, wurde das Paketmodel entlang einer Trajektorie innerhalb der Aufwindregion initialisiert. Diese Trajektore wurde durch dreidimensionale Simulationen eines pyro-konvektiven Ereignisses durch das Model ATHAM berechnet. Es zeigt sich, dass die Anzahlkonzentration der Wolkentropfen mit steigender Aerosolkonzentration ansteigt. Auf der anderen Seite verringert sich die Größe der Wolkentropfen mit steigender Aerosolkonzentration. Die Reduzierung der Verbreiterung des Tropfenspektrums stimmt mit den Ergebnissen aus Messungen überein und unterstützt das Konzept der Unterdrückung von Niederschlag in stark verschmutzen Wolken.Mit Hilfe des Models ATHAM wurden die dynamischen und mikrophysikalischen Prozesse von pyro-konvektiven Wolken, aufbauend auf einer realistischen Parametrisierung der Aktivierung von Aerosolpartikeln durch die Ergebnisse der Aktivierungsstudie, mit zwei- und dreidimensionalen Simulationen untersucht. Ein modernes zweimomenten mikrophysikalisches Schema wurde in ATHAM implementiert, um den Einfluss der Anzahlkonzentration von Aerosolpartikeln auf die Entwicklung von idealisierten pyro-konvektiven Wolken in US Standardamtosphären für die mittleren Breiten und den Tropen zu untersuchen. Die Ergebnisse zeigen, dass die Anzahlkonzentration der Aerosolpartikel die Bildung von Regen beeinflusst. Für geringe Aerosolkonzentrationen findet die rasche Regenbildung hauptsächlich durch warme mikrophysikalische Prozesse statt. Für höhere Aerosolkonzentrationen ist die Eisphase wichtiger für die Bildung von Regen. Dies führt zu einem verspäteten Einsetzen von Niederschlag für verunreinigtere Atmosphären. Außerdem wird gezeigt, dass die Zusammensetzung der Eisnukleationspartikel (IN) einen starken Einfluss auf die dynamische und mikrophysikalische Struktur solcher Wolken hat. Bei sehr effizienten IN bildet sich Regen früher. Die Untersuchung zum Einfluss des atmosphärischen Hintergrundprofils zeigt eine geringe Auswirkung der Meteorologie auf die Sensitivität der pyro-konvektiven Wolken auf diernAerosolkonzentration. Zum Abschluss wird gezeigt, dass die durch das Feuer emittierte Hitze einen deutlichen Einfluss auf die Entwicklung und die Wolkenobergrenze von pyro-konvektive Wolken hat. Zusammenfassend kann gesagt werden, dass in dieser Dissertation die Mikrophysik von pyrokonvektiven Wolken mit Hilfe von idealisierten Simulation eines Wolkenpaketmodell mit detaillierte spektraler Mikrophysik und eines 3D Modells mit einem zweimomenten Schema im Detail untersucht wurde. Es wird gezeigt, dass die extremen Bedingungen im Bezug auf die vertikale Windgeschwindigkeiten und Aerosolkonzentrationen einen deutlichen Einfluss auf die Entwicklung von pyro-konvektiven Wolken haben.

Forward modelling of petrological crust-forming processes on the early Earth

Tonalite-trondhjemite-granodiorite (TTG) gneisses form up to two-thirds of the preserved Archean continental crust and there is considerable debate regarding the primary magmatic processes of the generation of these rocks. The popular theories indicate that these rocks were formed by partial melting of basaltic oceanic crust which was previously metamorphosed to garnet-amphibolite and/or eclogite facies conditions either at the base of thick oceanic crust or by subduction processes.rnThis study investigates a new aspect regarding the source rock for Archean continental crust which is inferred to have had a bulk compostion richer in magnesium (picrite) than present-day basaltic oceanic crust. This difference is supposed to originate from a higher geothermal gradient in the early Archean which may have induced higher degrees of partial melting in the mantle, which resulted in a thicker and more magnesian oceanic crust. rnThe methods used to investigate the role of a more MgO-rich source rock in the formation of TTG-like melts in the context of this new approach are mineral equilibria calculations with the software THERMOCALC and high-pressure experiments conducted from 10–20 kbar and 900–1100 °C, both combined in a forward modelling approach. Initially, P–T pseudosections for natural rock compositions with increasing MgO contents were calculated in the system NCFMASHTO (Na2O–CaO–FeO–MgO–Al2O3–SiO2–H2O–TiO2) to ascertain the metamorphic products from rocks with increasing MgO contents from a MORB up to a komatiite. A small number of previous experiments on komatiites showed the development of pyroxenite instead of eclogite and garnet-amphibolite during metamorphism and established that melts of these pyroxenites are of basaltic composition, thus again building oceanic crust instead of continental crust.rnThe P–T pseudosections calculated represent a continuous development of their metamorphic products from amphibolites and eclogites towards pyroxenites. On the basis of these calculations and the changes within the range of compositions, three picritic Models of Archean Oceanic Crust (MAOC) were established with different MgO contents (11, 13 and 15 wt%) ranging between basalt and komatiite. The thermodynamic modelling for MAOC 11, 13 and 15 at supersolidus conditions is imprecise since no appropriate melt model for metabasic rocks is currently available and the melt model for metapelitic rocks resulted in unsatisfactory calculations. The partially molten region is therfore covered by high-pressure experiments. The results of the experiments show a transition from predominantly tonalitic melts in MAOC 11 to basaltic melts in MAOC 15 and a solidus moving towards higher temperatures with increasing magnesium in the bulk composition. Tonalitic melts were generated in MAOC 11 and 13 at pressures up to 12.5 kbar in the presence of garnet, clinopyroxene, plagioclase plus/minus quartz (plus/minus orthopyroxene in the presence of quartz and at lower pressures) in the absence of amphibole but it could not be explicitly indicated whether the tonalitic melts coexisting with an eclogitic residue and rutile at 20 kbar do belong to the Archean TTG suite. Basaltic melts were generated predominantly in the presence of granulite facies residues such as amphibole plus/minus garnet, plagioclase, orthopyroxene that lack quartz in all MAOC compositions at pressures up to 15 kbar. rnThe tonalitic melts generated in MAOC 11 and 13 indicate that thicker oceanic crust with more magnesium than that of a modern basalt is also a viable source for the generation of TTG-like melts and therefore continental crust in the Archean. The experimental results are related to different geologic settings as a function of pressure. The favoured setting for the generation of early TTG-like melts at 15 kbar is the base of an oceanic crust thicker than existing today or by melting of slabs in shallow subduction zones, both without interaction of tonalic melts with the mantle. Tonalitic melts at 20 kbar may have been generated below the plagioclase stability by slab melting in deeper subduction zones that have developed with time during the progressive cooling of the Earth, but it is unlikely that those melts reached lower pressure levels without further mantle interaction.rn

Measuring attitudes, behaviours, and influences in inner city victims of interpersonal violence (VIVs) - a Swiss emergency room pilot study

Background Switzerland is confronted with the problem of interpersonal violence. Violence is in the increase and the potential for aggression seems to be rising. Observations by hospitals discern an appalling increase of the severity of the injuries. The aim of this study is to collect accurate information about the social environment, the motivation and possible reasons for violence. We also intend to investigate whether sociocultural, or ethnic differences among male victims exist. Materials and methods For the first time in Switzerland, this survey employed a validated questionnaire from the division of violence prevention, Atlanta, Georgia. The first part of the questionnaire addressed social and demographic factors which could influence the risk of violence: age, gender, duration of stay in Switzerland, nationality and educational level. Beside these social structural factors, the questionnaire included questions on experience of violent offences in the past, information about the most recent violent offence and intra and interpersonal facts. The questionnaire itself consists of 27 questions, translated into German and French. In a pilot study, the questionnaire was checked with adolescents for feasibility and comprehensibility. Results 69 male VIVs were interviewed at two hospitals in the Canton of Bern. Most of the adolescents emphasised that weapons were not used during their confrontations. It is astonishing that all of the young men considered themselves to be victims. Most of the brawls were incited after an exchange of verbal abuse and provocations with unfamiliar individuals. The rivals could neither be classified with the help of ethnic categories nor identifiable groups of the youth scenes. The incidents took place in scenes, where violence was more likely to happen. Interestingly and contrary to a general perception the offenders are well integrated into sport and leisure clubs. A further surprising result of our research is that the attitude towards religion differs between young men with experience of violence and non-violent men. Discussion Youth violence is a health issue, which concerns us globally. The human and economic toll of violence on victims and offenders, their families, and on society in general is high. The economic costs associated with violence-related illness and disability is estimated to be millions of Swiss francs each year. Physicians and psychologists are compelled to identify the factors, which cause young people to be violent, to find out which interventions prove to be successful, and to design effective prevention programs. The identification of effective programs depends on the availability of reliable and valid measures to assess changes in violence-related attitudes. In our efforts to create healthier communities, we need to investigate; document and do research on the causes and circumstances of youth violence.

Extremely Violent Societies: Mass Violence in the Twentieth Century World

In this groundbreaking book Christian Gerlach traces the social roots of the extraordinary processes of human destruction involved in mass violence throughout the twentieth century. He argues that terms such as 'genocide' and 'ethnic cleansing' are too narrow to explain the diverse motives and interests that cause violence to spread in varying forms and intensities. From killings and expulsions to enforced hunger, collective rape, strategic bombing, forced labour and imprisonment he explores what happened before, during, and after periods of widespread bloodshed in countries such as Armenia, Indonesia, Bangladesh, Nazi-occupied Greece and in anti-guerilla wars worldwide in order to highlight the crucial role of socio-economic pressures in the generation of group conflicts. By focussing on why so many different people participated in or supported mass violence, and why different groups were victimized, he offers us a new way of understanding one of the most disturbing phenomena of our times.
