Criminal Case Processing of Sexual Assaults in Alaska

Discretion plays a role in nearly every facet of the American criminal justice system. It is widely regarded as necessary to do justice but is not without criticisms – especially when it leads to unfavorable or disparate treatment. The role of discretion in sexual assault cases has been particularly scrutinized. Since the majority of sexual assaults do not fit stereotypic beliefs about what constitutes a “real rape” and “genuine victim,” criminal justice officials use their discretion to filter these cases out of the justice system. This study explored this issue by examining two stages of the criminal justice process: the police decision to refer cases for prosecution and the prosecutorial decision to accept referred cases. In doing so, it contributes to this body of literature in three ways. First, it included sexual assault cases that involve Alaska Native victims and suspects. Second, it addressed a gap in the theoretical scholarship by examining the downstream nature of police decision-making. And finally, it examined the formal reasons prosecutors give for charge dispositions. This study found a significant amount of attrition of sexual assault cases as they progressed through the criminal justice system. Moreover, a combination of legally relevant and extralegal factors was found to be important, but not consistently across all types of sexual assaults. Among legal factors, the number of victim injuries was the most consistent predictor. Among extralegal factors, cases that involved Alaska Native suspects had significantly higher odds of case referral and case acceptance compared to white suspects. The effect of suspect race was particularly pronounced in cases with a white victim. Additionally, the findings suggest that not only are Native American defendants more likely to have their cases referred by police, but once referred, they are also more likely to have them accepted for prosecution. Contrary to expectations, victim-suspect relationship, specifically non-stranger assaults, increased the odds of police referral compared to stranger cases. However, the opposite appears to be true for the decision to prosecute cases. Once referred, prosecutors were five times more likely to accept sexual assaults perpetrated by strangers. The implications of these findings are also discussed.

Role of Serum Levels of Vascular Endothelial Growth Factor and Its Receptor in Retinopathy of Prematurity

Background: Retinopathy of prematurity (ROP) is a disorder of developing retina of low birth weight preterm infants which can lead to blindness. One theory attributes the fibrosis seen in ROP to deregulation of vascularization in the retina. Vascular endothelial growth factor (VEGF) is one of the important mediators involved in vascularization. Objectives: This study was carried out to assess the role of VEGF and its receptor in retinopathy of prematurity. Patients and Methods: Around 200 preterm infants born in SSK hospital were screened at 33 - 34 weeks. These babies were followed up according to the international classification of retinopathy of prematurity (ICROP) criteria. Those infants who developed ROP at 38 - 40 weeks were enrolled in group A while an equal number of infants who did not develop ROP were included in group B. Each group comprised of 30 subjects each. Venous sampling was carried out twice, once at 33 - 34 weeks and then again at 38 - 40 weeks. VEGF and VEGF-R2 were estimated by commercially available ELISA kits. Results: There was no statistically significant difference between the levels of VEGF and VEGF-R2 in both groups at first visit as well as the follow up visit. However, the intra-group difference was significant between the first and the final visit in VEGF and VEGF-R2 levels in the cases with ROP. In the control population, the VEGF levels were significantly lower in the follow up visit as compared to the initial visit. Conclusions: Our study demonstrates that a significant difference is seen in the serum VEGF and VRGF-R2 in the second visit of the infants with ROP demonstrating that VEGF might be responsible for the initiation and aggravation of ROP.

Evaluation of the Effect of Passive Smoking on Lactoferrin and AST on 12 - 15 Years Old Children and Adolescents

Background: Passive smokers are involuntarily exposed to cigarette or tobacco smoke and as known, inhalation of environmental tobacco smoke is a serious threat. There is little information about the effect of passive smoking on salivary markers and periodontal indices. Objectives: This study investigated the effect of passive smoking on lactoferrin and AST in 12 - 15 years old children and adolescents. Patients and Methods: This case-control analytic correlation type study with no-convenience random sampling method was performed on 160 children aged 12 - 15 who had smokers in their families. The eligible children were divided into two equal groups; 80 cot+ children as case group and 80 cot– children as control group, matched according to age, sex and plaque index. Plaque index was obtained from all subjects. 2 cc unstimulated salivary samples were collected by spitting method. The collected specimens were tested by lactoferrin and AST kits in biochemistry were measured on the day of sampling laboratory. Gingival index Loe and Silness (GI) and Probing Pocket Depth (PPD). Results: Mean and Standard Deviation of PPD and GI was 2.01 ± 0.077 and 1.53 ± 0.055 in experimental group and 1.93 ± 0.073 and 1.49 ± 0.046 in control group respectively (P < 0.001). The Mean and Standard Deviation parameters of lactoferrin and AST, in the experimental group was 38.66 ± 25.15 and 13.45 ± 6.33 and in the control group 10.18 ± 6.82 and 6.53 ± 2.65 group, respectively (P < 0.001). Conclusions: Passive smoking can be effective on inflammatory process of periodontal and salivary biomarkers related to inflammation. Lactoferrin was 11 - 104 in case group and 0.5 - 38 in control group. Aspartat aminotransferase in case group was 2.64 - 30.43 and in control group it was 2.16 - 12.02.

The effect of sample and sample matrix on DNA processing: Mechanisms for the detection and management of inhibition in forensic samples

The presence of inhibitory substances in biological forensic samples has, and continues to affect the quality of the data generated following DNA typing processes. Although the chemistries used during the procedures have been enhanced to mitigate the effects of these deleterious compounds, some challenges remain. Inhibitors can be components of the samples, the substrate where samples were deposited or chemical(s) associated to the DNA purification step. Therefore, a thorough understanding of the extraction processes and their ability to handle the various types of inhibitory substances can help define the best analytical processing for any given sample. A series of experiments were conducted to establish the inhibition tolerance of quantification and amplification kits using common inhibitory substances in order to determine if current laboratory practices are optimal for identifying potential problems associated with inhibition. DART mass spectrometry was used to determine the amount of inhibitor carryover after sample purification, its correlation to the initial inhibitor input in the sample and the overall effect in the results. Finally, a novel alternative at gathering investigative leads from samples that would otherwise be ineffective for DNA typing due to the large amounts of inhibitory substances and/or environmental degradation was tested. This included generating data associated with microbial peak signatures to identify locations of clandestine human graves. Results demonstrate that the current methods for assessing inhibition are not necessarily accurate, as samples that appear inhibited in the quantification process can yield full DNA profiles, while those that do not indicate inhibition may suffer from lowered amplification efficiency or PCR artifacts. The extraction methods tested were able to remove >90% of the inhibitors from all samples with the exception of phenol, which was present in variable amounts whenever the organic extraction approach was utilized. Although the results attained suggested that most inhibitors produce minimal effect on downstream applications, analysts should practice caution when selecting the best extraction method for particular samples, as casework DNA samples are often present in small quantities and can contain an overwhelming amount of inhibitory substances.^

Consecuencias literarias del 11-S: la representación de la violencia en la novela angloamericana

In my eight years as a professional journalist, I have been a front line observer of the extreme level of violence which occurs everyday in our society. As victims, consumers or perpetrators of violence, this phenomenon is now a part of our existence. As a reporter for the Spanish national newspaper El País I have been witness to the most terrible acts of violence. In Venezuela, with one of the highest rates of criminality in the world, I saw piles of bodies stacked up in mortuaries. In Argentina, I reported on the most brutal crimes including the rape of children by policemen. I believe that my interest in the manifestations and causes of violence was aroused during my time as a journalist. On a personal level, I was deeply affected by the twin poles of attraction/repulsion which the violent images produced in me. The first time I visited New York in 2003, I talked to various people who were selling photos of the victims of the Twin Tower attacks. They had laid out their wares along the wire fence that separated Ground Zero from the main public areas. One particular photograph made an indelible impression on my mind: a ghost like corpse covered in white dust which was streaked with blood. It is an image I will never forget. If I remember well, a complete album of these gruesome images cost about ten dollars. At the same time, I also became interested in islamic terrorism: its complexity and the great impact it has made on Western society. One only has to look at the front page of the press around the world to read about war, terrorism or the constant violation of human rights. The words Al-Qaeda, Daesh, Boko Haram and Islamic State have sadly become parts of our everyday language. The nihilistic philosophy which promisess eternal life in exchange for self-inmolation is a new, highly worrying reality, especially painful when it involves young people who become indoctrinated through the social media. They have become the most loyal supporters of a fanatical and uncompromising version of Islam. The stark reality is that these young recruits to Jihad (holy war) were born in places like London, Paris, Rome or Madrid...

The Ultimate Secrecy: Feminist Readings of Masculine Trauma in Vietnam War Literature

It is a widely acknowledged and often unquestioned fact that patriarchy and its modes of behaviour and social organization favour the appearance of trauma on the weakest (and defenceless) members of society: women. In the last decades, trauma seems to have taken the baton of typically female maladies such as 19th c. hysteria or 20th c. madness. Feminists in the 20th c. have long worked to prove the connection between the latter affections (and their reflection in literary texts) and patriarchal oppression or expectations of feminine behaviour and accordance to roles and rules. With Trauma Studies on the rise, the approach to the idea of the untold as related to femininity is manifold: on the one hand, is not trauma, which precludes telling about one’s own experience and keeps it locked not only from the others, but also from ourselves, the ultimate secrecy? On the other hand, when analyzing works that reflect trauma, one is astounded by the high number of them with a female protagonist and an almost all-female cast: in this sense, a ‘feminist’ reading is almost compulsory, in the sense that it is usually the author’s assumption that patriarchal systems of exploitation and expectations favour traumatic events and their outcome (silence and secrets) on the powerless, usually women. Often, traumatic texts combine feminism with other analytical discourses (one of the topics proposed for this panel): Toni Morrison’s study of traumatic responses in The Bluest Eye and Beloved cannot be untangled from her critique of slavery; just as much of Chicana feminism and its representations of rape and abuse (two main agents of trauma) analyze the nexus of patriarchy, new forms of post-colonialism, and the dynamics of power and powerlessness in ethnic contexts. Within this tradition that establishes the secrecies of trauma as an almost exclusively feminine characteristic, one is however faced with texts which have traumatized males as protagonists: curiously enough, most of these characters have suffered trauma through a typically masculine experience: that of war and its aftermath. By analyzing novels dealing with war veterans from Vietnam or the Second World War, the astounding findings are the frequent mixture of masculine or even ‘macho’ values and the denial of any kind of ‘feminine’ characteristics, combined with a very strict set of rules of power and hierarchy that clearly establish who is empowered and who is powerless. It is our argument that this replication of patriarchal modes of domination, which place the lowest ranks of the army in a ‘feminine’ situation, blended with the compulsory ‘macho’ stance soldiers are forced to adopt as army men (as seen, for example, in Philip Caputo’s Indian Country, Larry Heinemann’s Paco’s Story or Ed Dodge’s DAU: A Novel of Vietnam) furthers the onset and seriousness of ulterior trauma. In this sense, we can also analyze this kind of writing from a ‘feminist’ point of view, since the dynamics of über-patriarchal power established at the front at war-time deny any display of elements traditionally viewed as ‘feminine’ (such as grief, guilt or emotions) in soldiers. If trauma is the result of a game of patriarchal empowerment, how can feminist works, not only theoretical, but also fictional, overthrow it? Are ‘feminine’ characteristics necessary to escape trauma, even in male victims? How can feminist readings of trauma enhance our understanding of its dynamics and help produce new modes of interaction that transcend power and gender division as the basis for the organization of society?

Evaluation of five commercial methods for the extraction and purification of DNA from human faecal samples for downstream molecular detection of the enteric protozoan parasites Cryptosporidium spp., Giardia duodenalis, and Entamoeba spp

High quality, pure DNA is required for ensuring reliable and reproducible results in molecular diagnosis applications. A number of in-house and commercial methods are available for the extraction and purification of genomic DNA from faecal material, each one offering a specific combination of performance, cost-effectiveness, and easiness of use that should be conveniently evaluated in function of the pathogen of interest. In this comparative study the marketed kits QIAamp DNA stool mini (Qiagen), SpeedTools DNA extraction (Biotools), DNAExtract-VK (Vacunek), PowerFecal DNA isolation (MoBio), and Wizard magnetic DNA purification system (Promega Corporation) were assessed for their efficacy in obtaining DNA of the most relevant enteric protozoan parasites associated to gastrointestinal disease globally. A panel of 113 stool specimens of clinically confirmed patients with cryptosporidiosis (n = 29), giardiasis (n = 47) and amoebiasis by Entamoeba histolytica (n = 3) or E. dispar (n = 10) and apparently healthy subjects (n = 24) were used for this purpose. Stool samples were aliquoted in five sub-samples and individually processed by each extraction method evaluated. Purified DNA samples were subsequently tested in PCR-based assays routinely used in our laboratory. The five compared methods yielded amplifiable amounts of DNA of the pathogens tested, although performance differences were observed among them depending on the parasite and the infection burden. Methods combining chemical, enzymatic and/or mechanical lysis procedures at temperatures of at least 56 °C were proven more efficient for the release of DNA from Cryptosporidium oocysts.

La réception par les hommes de la campagne "My Strength" visant à les mobiliser contre les agressions sexuelles, étudiée au prisme du genre

Ce mémoire porte sur la réception par des hommes de publicités sociales développées dans le cadre de la campagne My Strength is Not for Hurting par l’organisme américain Men Can Stop Rape. Le but était de comprendre le sens qu’ils donnent à des messages publicitaires conçus pour les interpeller par une caractéristique traditionnellement associée au masculin afin qu’ils se mobilisent dans la prévention des agressions sexuelles. Le concept de genre, élaboré en référence au système normatif qui crée les sexes et les hiérarchise, les notions de masculinité hégémonique et de masculinités plurielles ont servi de cadre théorique à cette étude féministe, tout comme la réception médiatique. Les propos de sept hommes engagés politiquement ou socialement ont été analysés avec l’approche de la psychologie discursive en analyse de discours. L’analyse qualitative réalisée montre que les participants articulent une réception négociée du message publicitaire. Ils en captent le sens sans s’y identifier, critiquent le discours hégémonique sur la masculinité perçu dans le message publicitaire, et s’engagent dans un processus d’altérisation pour résoudre leur malaise à l’égard du viol en construisant une subjectivité masculine spécifique et opposée à celle d’hommes qu’ils considèrent à risque de commettre ce crime. Les rapports de pouvoir femmes-hommes sont évacués de la discussion, bien que les participants tiennent, hors de la discussion sur My Strength, un propos avisé sur la mobilisation des hommes pour prévenir les agressions sexuelles. Cette analyse qualitative met au jour le caractère pluriel et hiérarchique de la masculinité et l’obligation d’en tenir compte dans un processus de persuasion visant à mobiliser les hommes pour prévenir les agressions sexuelles. Elle souligne également la nécessité d’éviter la reconduction de la masculinité hégémonique dans les messages pour que soient mis au jour les rapports de pouvoir qui forgent l’agression sexuelle, enjeu dévoilé par le mouvement féministe.

Implicaciones humanitarias de la contratación de empresas militares privadas (PMC) por parte de los Estados. Estudio de caso; Estados Unidos y Blackwater en Irak (2003-2007)

La presente investigación tiene como finalidad analizar las implicaciones humanitarias de la participación de las Compañías Militares Privadas (PMC) contratadas por los Estados en escenarios de conflicto, a partir del caso de Blackwater y Estados Unidos en Irak (2003-2007), con el fin de mostrar a través de algunos hechos específicos como el acaecido en la plaza Al Nisour los vacíos existentes en la regulación de sus actividades. Frente a estos hechos se muestra como la Comunidad Internacional ha tratado de avanzar en la creación de un régimen internacional que las controle, sin embargo, como se evidencia a lo largo de este escrito la falta de compromiso por parte de los Estados ha hecho que esta tarea se vea obstaculizada y por lo tanto la actuación de estas compañías se encuentra aún en una zona jurídica gris.
