Karachi violence putting NATO troops in Afghanistan at risk

There is a threat to Nato forces in Afghanistan which the world is ignoring. Violent gangs have been killing indiscriminately in Karachi, the Pakistani city vital to the supply chain which sustains ISAF forces in their fight against the Taliban.

Bloods, Crips and Southern Cross Soldiers: we are all gangbangers now!

This paper presents findings from the author's PhD thesis exploring violent youth subcultures in Australia. It addresses whether growing uncertainties around issues of cultural identity and belonging in an era of risk has produced more defensive models of DIY youth culture at a local scale. Theoretically, the author examines whether globalisation has unsettled normative youth subject positions associated with the nation-state, problematising conventional logics of youth cultural formation (i.e. which view questions of race and racism through a white/black, mainstream/subculture binary). As Beck (1992;1999) argues, the de-bounding influence of globalisation has led to an ambivalent set of relations where forms of youth identity have become freed from the nation-state and class based forms of community and must be self-organised. In particular, he argues that this has produced cosmopolitan subjects and social movements as well as ‘counter-modern’ subjects and cultures. This paper applies Beck’s theories alongside theories focused on global/local influences on youth culture to an ethnographic study of two violent youth subcultures in Australia, these being the white ‘patriotic’ youth formation which emerged in the Cronulla riots and youth gang formations in Melbourne’s western suburbs. In doing so the author examines the extent to which violent youth subcultures in Australia can be regarded as strategic responses intended to restore forms of collective cultural belonging at a local scale vis a vis ‘the global’ and its destabilizing influences.

O crime de drogas e a violência em São Paulo: uma análise a partir da Lei de Drogas

O objetivo desta pesquisa é estudar o efeito da Lei nº 11.343/06 (Lei de Drogas) sobre o crime de tráfico e porte de drogas e a relação entre crimes de drogas e outros crimes. Para isso, são exploradas as variações da Lei de Drogas, através de análises de regressões com descontinuidade e com variável instrumental, além de estimações com dados em painel, em busca de um efeito causal entre drogas e violência. Como resultados, a Lei de Drogas parece não ter efeito negativo significativo sobre crimes de drogas. Por outro lado, crimes de drogas apresentam uma associação negativa sobre crimes de furto e uma relação positiva com crimes de formação de quadrilha. Para cada redução de 100 crimes de drogas (por mil habitantes) associa-se um aumento de 3,6 crimes de furto (por mil habitantes) e uma diminuição de 27 crimes de formação de quadrilha (por mil habitantes). Não são encontrados efeitos robustos sobre roubos, homicídios, latrocínios, estupros, crimes de lesão corporal e porte de arma de fogo.

Drug battles and school achievement: evidence from Rio de Janeiro's favelas

This paper examines the effects of armed conflicts between drug gangs in Rio de Janeiro's favelas on student achievement. We explore variation in violence that occurs across time and space when gangs battle over territories. Within-school estimates indicate that students from schools exposed to violence score less in math exams. The effect of violence increases with conflict intensity, duration, and proximity to exam dates; and decreases with the distance between the school and the conflict location. Finally, we find that school supply is an important mechanism driving the achievement results; armed conflicts are significantly associated with higher teacher absenteeism, principal turnover, and temporary school closings.

Análise de aspectos ergonômicos do colete tático - um estudo de caso na ROCAM-RN

This thesis aims to analyze the ergonomic and functional aspects of the motorcycle patrolmen tactical vest and make a contribution to improve their technical and tactical characteristics reconciling pleasantness function, improving working conditions of policeman. The start point of this case study was the following hypothesis : The start point of this case study was the following hypothesis: once the policemen prepare their own tactical vests with layouts created by them. So, if someone observes these layouts, s/he will have an understanding of use of those devices and artifacts questions both positive, and negative. This hypothesis was confirmed by the results, considering that it was possible to understand the use of the tactic vests by means of the Policemen s opinion on issues recognized by themselves. It was also possible to understand that users perform interventions, based on their own inventive or learned from the experience of other policemen

Avaliação da gravidade do trauma em condutores de motocicleta vítimas de acidentes de trânsito no Rio Grande do Norte

Descriptive exploratory study, prospective, with quantitative approach, performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGHC), in Natal/RN, aiming to identify injuries by body area and wound severity on drivers who suffered motorcycle accidents, evaluate the severity of injuries and trauma on these drivers and identify the existence of association between wound and trauma severity and some of the accident s characteristics. The population comprised 371 motorcycle drivers, with data collected between October and December 2007. We used as instruments the Abberviated Injury Scale (AIS), Injury Severity Score (ISS) and the Glasgow Coma Scale (GCE1). The results show that, concerning characterization, there was a predominance of the male gender (88.4%), aged between 18 and 24 years (39.90%), originating from the Natal metropolitan region (55.79%), with fundamental-level instruction (51.48%), catholic (75.78%), married (47.98%). 23.18% work on commerce-related activities and 75.20% have income of up to 2 minimum wages. As for the accident s characteristics, the predominant shift was the afternoon (46.36%), received up to one hour after the event (50.67%), transported by countryside ambulances colleagues and relatives (51.21%), 25.34% had the accident on Sunday; 53.91% suffered falls and vehicle rolls; among the collisions there was a predominance of the motorcycle-automoblie type (28.03%); 52,6% were licensed and among these 50.76% had up to one year of license; 65.50% declared not having suffered previous accidents; 65.77% declared waring helmets in the time of the accident; 57.41% said not to have used drugs, and among those who used, alcohol was the most consumed (98.10%). The lowest score evaluated by GCS1 (3 to 8) was linked to drivers who suffered accidents on Saturday (10.3%), those who were not wearing helmets (14.29%) and the victims of motorcycle-pedestrian/animal crashes (13.33%). The body areas most affected had AIS between 1 and 3 (95.76%) and were: external surface (39.90%) and head/neck (33.20%). As for trauma severity, the highest scores (ISS>25) belonged to those who consumed alcohol (30.73%), suffered falls or vehicle rolls (48.9%) and those attended to 3 hours or longer after the accident (50%). We conclude that for motorcycle drivers who suffered accidents, age, gender, weekday, type of accident, use of drugs and the absence of helmet use signal both to the risk of occurrence of these events, as well as for the greater severity of injuries and trauma.

Caracterização do acidente de trânsito e gravidade do trauma: um estudo em vítimas de um hospital de emergência de Natal

Descriptive exploratory study, with quantitative approach and prospective data performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGH), in Natal/RN, aiming to classify the type of motor vehicle involved in the accident, the public roadway s user quality and the more frequent injuries; to evaluate the severity of trauma in traffic accident victims; characterized the severity of the injuries and the trauma, and the type of motor vehicle involved. The population comprises 605 traffic accident victims, with data collected between October and December 2007. We used as a support for the evaluation of severity of injuries and trauma the Glasgow Coma Scale (GCSl), the Condensed Abbreviated Injury Scale (CAIS) and the Injury Severity Score (ISS). The results show that 82.8% of the victims were male; 78.4% were aged 18 to 38; the victims originating from the State s Countryside prevailed (43.1%); 24.3% of the population had completed middle-level instruction; 23.1% worked on commerce and auxiliary activities; most (79.4%) was catholic; 48.8% were married/consensual union; 76.2% earned up to two monthly minimum wages; Sunday was the day with the most accidents (25.1%); 47.4% were attended to in under an hour after the event; the motorcycle on its own was responsible for 53.2% of the accidents; 42.3% were attended to by the SAMU; 61.8% were victims of crashes; over half (53.4%) used individual protection equipment (IPE); 49.4% were helmets and 4.0% the seatbelt; 61.3% were motorcycle drivers; 43.3% of the accidents took place in the afternoon shift; from 395 drivers, 55.2% were licensed, and 50.7% among those had been licensed for 1 to 5 years; 90.7% of the victims had GCS1 between 13 and 15 points at the time of evaluation; the body area most affected was the external surface (35.9%); 38.8% of the injuries were light or moderate (AIS=1 and AIS=2); 83.2% had light trauma (ISS between 1 and 15 points). In face of the results, we can conclude that there is a risk for the elevation of injury severity and trauma resulting from traffic accidents, when these events are related to certain variables such as gender, age, weekday, the interval between the accident and the first care, ingestion of drugs, type of accident, the public roadway s user quality, the use of IPE, day shift, body regions and the type of motor vehicle involved in the accident

Occurrence of tooth injuries in patients treated in hospital environment in the region of Aracatuba, Brazil during a 6-year period

Dental trauma has been considered as a public health problem that affects mainly children and youngsters and due to its impact on the patient's quality of life. This study presents the results of a 6-year survey of the occurrence and characteristics of dental trauma in patients admitted to the Service of Surgery and Oral and Maxillofacial Traumatology of the School of Dentistry of Aracatuba (UNESP, Brazil) after emergency care in hospital facilities in the region of Aracatuba, SP, Brazil. For such purpose, the clinical files of patients treated at the Service between 1999 and 2005 were reviewed. Information regarding gender, age, number of traumatized teeth, etiology and diagnosis of the trauma was collected from the files of patients with tooth injuries and recorded in case report forms specifically designed for this purpose. The results showed that from a total of 4112 patients admitted to the Service within the surveyed period, 266 (6.5%) had tooth injuries (172 males - 64.7%; 94 females - 35.3%). The total number of traumatized teeth was 496. Most patients belonged to the 16-20 year-old age group (20.3%) and the most frequent causes of tooth injuries were bicycle accidents (28.6%), motorcycle accidents (19.2%) and falls (18.8%). Injuries to the periodontal tissues were the most frequent type of tooth injuries (408 teeth; 82.26%), occurring in 118 primary and 290 permanent teeth. Among the injuries to the periodontal tissues, avulsion was the most common (32.86%) (29.41% for primary and 34.0% for permanent teeth), followed by extrusive luxation (19.15%) (25.21% for primary and 17.24% for permanent teeth). In conclusion, in the surveyed population, cases of tooth injuries were more frequent in males aged 16-20 years old due to cyclist accidents with predominance of injuries to the periodontal tissues, in particular, avulsions.

Adaptation of the reservoir fish assemblage index (RFAI) for assessing the Barra Bonita Reservoir (São Paulo, Brazil)

In order to evaluate the environmental condition of the Barra Bonita Reservoir, we adapted the Index of Biotic Integrity (IBI). We chose 24 sampling sites in which three types of habitats were sampled: the mouths of tributaries, the central reservoir and the lateral reservoir. Fish were caught in two seasons (dry and rainy) using 10 gillnet gangs, with meshes ranging from 3 to 12 cm between opposite knots, and funnel traps. Abiotic and biotic variables were measured. Due to the artificial nature of the reservoir, the term biotic integrity was considered inappropriate and the term RFAI (Reservoir Fish Assemblage Index) was adopted. Twelve metrics from sixteen possibles were selected using the Pearson correlation coefficient. The reference conditions were set up based on the criteria of the best condition observed. For each metric, a score of 1, 3 or 5 was assigned as it strongly departs (1), slightly departs (3) or approaches (5) the reference condition. The index value is the sum of the metrics partial scores and ranges from 12 to 60. To evaluate the importance of the unit of measurement of the metric, the index was calculated in fish number (RFAI(N)) and in weight (RFAI(w)). The correlation between RFAIN and RFAIw was very high (r = 0.90, n = 46) indicating that the unit of measurement does not influence the final result of the index. Most of the sampling sites were classified in the 'reasonable' RFAI category. Only the central sites were classified as 'poor'. To validate the RFAI, another index, the Habitat Quality Index (HQI), was built starting from the physiochemical and habitat variables collected. The correlation of the RFAI with the HQI was highly significant (RFAIN, r = 0.37; RFAI(w), r = 0.47; n = 46), indicating that they respond in the same way to environmental degradation. The HQI metrics which most affect RFAI were depth, surrounding landscape and macrophyte presence/absence. Copyright C) 2007 John Wiley & Sons, Ltd.

Reconstrução do L.C.P. do joelho: técnica de fixação no leito tibial (INLAY). Avaliação objetiva e subjetiva de 30 casos

A reconstrução cirúrgica do ligamento cruzado posterior (L.C.P.) do joelho ainda permanece como um grande desafio terapêutico. Neste trabalho avaliamos 30 pacientes submetidos à reconstrução cirúrgica do L.C.P. com a técnica de fixação do enxerto tendíneo no leito tibial por abordagem direta (INLAY). 28 pacientes eram do sexo masculino e 2 do feminino, com idade média de 31,10 anos. O tempo médio de lesão foi de 34,24 meses em 67% dos casos a lesão foi secundária a acidente motociclístico. As lesões condrais e do ligamento cruzado anterior (L.C.A.) do joelho estavam presentes em 67% e 33% dos casos, respectivamente. Os pacientes foram avaliados objetivamente (teste de gaveta posterior) e subjetivamente (Escala de Lysholm). O seguimento pós-operatório médio foi de 21,7 meses. Cerca de 66% dos casos foram classificados como bom e excelente na avaliação subjetiva e objetiva. A análise estatística apresentou comportamento semelhante para as duas avaliações.Os resultados clínicos pós-operatórios obtidos neste trabalho têm nos encorajado a seguir com esta técnica cirúrgica.

Tratamento cirúrgico da fratura-avulsão da inserção tibial do L.C.P. do joelho: experiência de 21 casos

Avaliamos 21 pacientes, sendo 16 pacientes do sexo masculino e 5 do feminino, com idade média de 30 anos, foram submetidos à tratamento cirúrgico da fratura-avulsão do LCP. em 57% dos casos a lesão foi secundária a acidente motociclístico e 19% a acidente automobilístico. em 72% dos casos foi identificada uma lesão na face anterior do joelho. O tratamento cirúrgico consistiu na abordagem posterior do joelho e fixação do fragmento ósseo com parafuso e arruela em 18 casos; e amarrilhas trans-ósseas em 3 casos, onde o fragmento ósseo era muito pequeno. em 91% dos casos, a cirurgia foi realizada dentro dos primeiros 15 dias apos a lesão. Os pacientes foram avaliados objetivamente (teste de gaveta posterior) e subjetivamente (Escala de Lysholm), apos um seguimento pós-operatório mínimo de 12 meses. A análise estatística não mostrou diferença significativa, ao nível de 5%, entre as avaliações objetiva e subjetiva. A ausência de lesão ligamentar periférica pode ter contribuído para que os resultados clínicos pós-operatórios tenham avaliação subjetiva satisfatória; entretanto, a presença de uma posteriorização tibial residual sugere que a fratura-avulsão do ligamento cruzado posterior deve ser abordada não como uma lesão óssea pura, mas sim, como uma lesão ósteo-ligamentar.

Epidemiologic Evaluation of Mandibular Fractures in the Rio de Janeiro High-Complexity Hospital

The aim of this study was to gather data on trauma etiology and mandibular fracture localization in patients who presented at the General Hospital of Nova Iguacu, Rio de Janeiro, Brazil. From March 2007 to December 2008, 95 patients with mandibular fracture were registered in a medical form, at the Bucomax-illofacial Surgery Department of the General Hospital of Nova Iguacu, Rio de Janeiro, Brazil. Concerning mandibular fracture etiology, 21.05% were caused by motorcycle accidents, followed by interpersonal violence without use of weapons (punches, kicks, bumps with the head, blows with the elbow, etc) (16.84%) and interpersonal violence with firearm (14.73%). It was found that 52.63% of the patients had a single fracture line. The most affected fracture area was the parasymphysis (26.02%), followed by the condyle (22.60%) and mandibular angle (18.49%). Concerning the injury area, 24.21% were directed to the mandibular symphysis, 22.17% of the patients did not remember the injury area, and 18.94% had multiple injuries. When the injury was directed to the symphysis, the result was more condyle fractures (11.64%), and injuries at the mandibular angle resulted in fractures at the angle itself (8.90%). The most common fracture cause was traffic accidents, mainly motorcycle accidents, and the most affected areas were the parasymphysis and the condyle. The mandible isolated fractures occurred in half of the cases. Motorcycle accidents resulted in more fractures in the parasymphysis area, and when the symphysis area is affected by injuries, the result is a higher percentage in condyle fractures.
