The needs and experiences of women in sexually integrated prisons

Three issues were considered in this evaluation of the usefulness of co-corrections: violence, over-management and policies about sexuality. A study of one sexually integrated prison showed that co-corrections has both advantages and disadvantages for women. Inmates and staff were included in the research. Survey and anecdotal data were collected. The strengths of co-corrections were described from the data along with some suggestions for overcoming the weaknesses.     

Host discrimination by Hyposoter exiguae (Hymenoptera: Ichneumonidae)

Host discrimination byHyposoter exiguae (Viereck) was investigated, usingTrichoplusia ni (Hübner) as a host in the presence and absence of host food. Forty-six percent of the parasite females tested exhibited ovipositional patterns significantly different from a random distribution. Of these, 82% showed patterns ranging from near perfect to slight discrimination.

Zusammenfassung In seiner Arbeit über die Biologie vonH. exiguae berichtet Puttler, da? Weibchen dieser Art offensichtlich nicht zwischen parasitierten und nichtparasitierten Wirtslarven unterscheiden k?nnen. Im Verlauf unserer Arbeiten überH. exiguae ergab sich, da? einige Weibchen doch zwischen solchen Larven Unterschiede machen. Die vorliegende Untersuchung legt quantitativ für Individuen und Gruppen den Grad der Unterscheidung fest. H. exiguae-Weibchen wurden zu 22–28 Raupen (sp?tes erstes bis frühes zweites Stadium) vonTrichoplusia ni (Hübner) gebracht, mit und ohne Wirtsnahrung, für verschiedenze Zeitr?ume. Nach der Exposition wurden die Wirtsraupen in 70% Alkohol abget?tet, seziert und die Zahl der Parasiteneier in jeder Raupe ermittelt. Die tats?chliche Verte?lung der Parasiteneier wurde verglichen mit der theoretischen Zufalls-(Poisson-)verteilung, bei Anwendung der x²-Analyse. Von 24 getesteten Weibchen zeigten 11 ein Eiablageverteilungsmuster, das von der Zufallsverteilung abwich, meist im sinne einer Ablehnung von schon parasitierten Wirten.

     

Homicide as Infectious Disease: Using Public Health Methods to Investigate the Diffusion of Homicide

This study examined the spatial and temporal movement of homicide in Newark, New Jersey from January 1982 through September 2008. We hypothesized that homicide would diffuse in a similar process to an infectious disease with firearms and gangs operating as the infectious agents. A total of 2,366 homicide incidents were analyzed using SaTScan v.9.0, a cluster detection software. The results revealed spatio-temporal patterns of expansion diffusion: overall, firearm and gang homicide clusters in Newark evolved from a common area in the center of the city and spread southward and westward over the course of two decades. This pattern of movement has implications in regards to the susceptibility of populations to homicide, particularly because northern and eastern Newark remained largely immune to homicide clusters. The theoretical and practical implications of the findings, as well as recommendations for future research, are discussed.

Analysis of hair after contamination with blood containing 6-acetylmorphine and blood containing morphine

The study was carried out to investigate external contamination of hair by blood in heroin-related post-mortem cases. Solutions were prepared containing 0.05, 0.1, 0.2, 0.5 and 3.0μg/mL of 6-monoacetylmorphine (6-AM) only or morphine only in human blood. Samples of approximately 3.2g of drug-free hair were contaminated by soaking in the blood solutions for 5min. They were then removed and left at room temperature. Approximately 0.5g of hair was collected from each of the blood soaked hair samples at 6h, 1, 2, 4 and 7 days after contamination. As each hair sample was collected it was shampoo-washed to prevent further drug absorption. Hair samples were analysed in triplicate using a fully validated method described previously. 6-AM broke down to morphine in all samples. In hair contaminated with blood containing 0.05, 0.1 and 0.2μg/mL 6-AM or morphine drug was either not detected or was detected below the limit of quantitation (0.2ng/mg hair) at all contamination times. In hair contaminated with blood spiked with 0.5μg/mL morphine, the concentration in hair ranged from 0.54 to 0.91ng/mg and in hair contaminated with blood spiked with 3.0μg/mL, from 3.25 to 5.77ng/mg. The concentrations of 6-AM ranged from 0.65 to 1.11ng/mg and morphine from 0.34 to 0.80ng/mg in hair contaminated with 0.5μg/mL 6-AM in blood. 6-AM ranged from 2.12 to 3.67ng/mg and morphine from 0.84 to 2.05ng/mg in hair contaminated with 3μg/mL 6-AM in blood. For 6-AM and morphine ANOVA statistical evaluation showed no significant difference among the concentrations over time.     

Investigation of markers to indicate and distinguish death due to alcoholic ketoacidosis, diabetic ketoacidosis and hyperosmolar hyperglycemic state using post-mortem samples

Data from 191 post-mortem cases where post-mortem blood beta-hydroxybutyrate (βHB) and acetone concentrations and vitreous humor glucose concentrations (where available) had been measured were retrospectively investigated to determine the markers required to identify and distinguish between Alcoholic Ketoacidosis (AKA), Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS). Blood βHB concentrations above 250 μg/mL were considered significant and it was shown to be the preferred marker of ketoacidosis. All cases with significant βHB detected also had acetone present (greater than 2mg/dL) demonstrating that acetone can be used as a marker to identify ketoacidosis and can be used to indicate when βHB measurement is necessary. Vitreous humor glucose concentrations above 6.9 mmol/L were considered high and indicative of hyperglycemia prior to death. Vitreous humor glucose concentrations can be used to distinguish between DKA and ketoacidosis from other causes and to identify deaths due to HHS. The data showed that ketoacidosis can occur without a history of alcoholism or diabetes. Many diabetics are undiagnosed for many years. Therefore, DKA or HHS should be considered in sudden or unexplained deaths and glucose should be routinely measured especially in cases with risk factors for diabetes including obesity, old age, a history of mental health problems or treatment with atypical antipsychotic drugs including clozapine, olanzapine, quetiapine and risperidone.     

Monitoring deliberate self-harm presentations to general hospitals

Monitoring of deliberate self-harm (DSH) presentations to hospitals (and in other settings) is receiving increased attention in many countries. This is due to greater recognition of the size of the problem and awareness of its relevance to suicide prevention policy initiatives, because of the strong association between DSH and suicide. A system for monitoring all DSH presentations has been in place in the general hospital in Oxford for 30 years. Based on our experience, in this paper we describe procedures for monitoring, including case definition and identification, linkage of persons and episodes in order to investigate repetition of DSH and other outcomes (including deaths), and data protection and ethical issues. We also provide details of how to carry out monitoring, including different models of data collection, and what data to collect. Finally we consider the potential uses of the data for both clinical and research purposes, including evaluation of national suicide prevention initiatives.
