Mental health diversion courts : some directions for further development

Recent years have seen a growth in the number of specialist courts operating in Australia, including those which aim to address the needs of mentally disordered offenders. This article describes some of the key characteristics of mental health courts, using case studies from the most established court in Australia, the South Australian Magistrates Court Diversion Program (MCDP). This is followed by a consideration of some factors that may affect the future development of this type of program. It is concluded that there is a need to pay careful attention to issues of risk assessment and risk management if the dual goals of improving both the health of individual and the safety of the community are to be realised.

Juvenile justice diversion in Victoria : a blank canvas?

Unlike many jurisdictions in Australia, Victoria has not adopted a legislative, court-based diversion scheme for addressing crime committed by children and young people. The state has also seen limited investment in diversionary programs and an over-reliance on discretionary police cautions. For young people in rural and regional areas, access to diversion programs and support services is especially limited. This article examines the limited diversionary options available in the current youth justice system, identifying strengths and opportunities. It concludes that legislated, court-based diversion schemes — assisted by community programs that provide appropriate intervention and support to those at risk of reoffending — are an essential means of addressing young people’s engagement in crime.

Mental health diversion courts: a two year recidivism study of a South Australian mental health court program.

The need to develop specialized judicial processes to deal with offenders with mental illnesses is now widely recognized and has led to the introduction of mental health court diversion programs around the world. At present, however, there is only limited evidence from which to assess the impact of these initiatives. This paper describes the South Australian model of diversion, with specific reference to the relationship between identified participant characteristics, program compliance rates, and re-offending outcomes. The results of a two-year recidivism study suggest that involvement with the program has a positive impact on recidivism, but that this is independent from the individual's level of success in the program. Lower risk offenders were more likely to achieve successful outcomes than those in the higher risk categories. The implications of these results, as well the factors that might inform the ongoing development of mental health court programs, are discussed.

Trade diversion and declining tariffs : evidence from Mercosur

This paper empirically examines the alternative posed by Richardson (1993) to the traditional view that trade integration may exacerbate inefficiencies through trade diversion. Richardson’s hypothesis boldly predicts that trade diversion may actually cause tariffs to decline! The hypothesis is fundamentally attributable to the presence of a political component in the governments’ objective functions. A cross-sectionally rich data-set on trade and tariffs from the Mercosur-pact countries, primarily Argentina, is used. The evidence yields surprising conclusions about the validity of the political economy construct in models of trade integration.

Comparison of prophylactic and therapeutic use of short-chain fatty acid enemas in diversion colitis: a study in Wistar rats

OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after post-operative day 40). The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006) and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

REVERSIBILITY OF ADENOMATOUS HYPERPLASIA IN THE GASTRIC STUMP AFTER DIVERSION OF BILE REFLUX IN RATS

Morphological and phenotypical patterns of proliferative epithelial lesions induced in the gastric stump mucosa by duodenal content reflux after Billroth II partial gastrectomy (BII) were evaluated in rats. Control animals were either sham-operated or submitted at different times after BII to Roux-en-Y (RY) surgical procedure which prevents duodenal reflux. The lesions were analysed using routine haematoxylin and eosin staining, immunohistochemical staining for pepsinogen isoenzyme 1 and histochemical procedures for mucins (paradoxical Concanavalin A, galactose oxidase Schiff and sialidase galactose oxidase Schiff reactions). Mucosal hyperplasia (H) was observed in the group submitted to BII procedure 6 weeks after surgery. Adenomatous hyperplasia (AH) also appeared 6 weeks after induction of the reflux and its incidence and size increased until the 54th week of the experiment. RY procedure performed in the normal animals at the beginning of the experiment or at the 24th week after BII gastrectomy led to a significantly lower incidence of AH which was related to the moment of surgery. Most of H was due to pyloric mucosal hyperplasia. AH consisted mainly of gastric type glands but in some animals glands of the intestinal type Were present probably originating from the intestinal mucosa. Six mucinous adenocarcinomas were observed, all of them of intestinal type. This study demonstrates that AH induced by BII procedure is a reversible lesion and that the anomalous epithelial proliferation in the stoma may lead to adenocarcinomas.

REDUCTION OF CELL PROLIFERATIVE ACTIVITIES OF GASTRIC STUMP ADENOMATOUS HYPERPLASIAS AFTER BILE REFLUX DIVERSION IN RATS

Previously we reported the majority of lesions induced hy bile reflux, in the absence of chemical carcinogens, in the rat remnant stomach to consist primarily of gastric type and secondarily of intestinal type cells, and that they are reversible after diversion of bile reflux. The present study was designed to evaluate changes in proliferative activities in cells of each type under these conditions. The frequency of adenomatous hyperplasia (AH) induced in the gastric stump mucosa by duodenal content reflux after Billroth II partial gastrectomy (BII) increased until the 54th week of the experiment. Roux-en-Y (RY) surgical procedure which prevents duodenal reflux performed at the 24th or 36th week after BII led to a decrease in AH. Cell content of the lesions was analyzed using routine H&E staining, immunohistochemical staining for pepsinogen isoenzyme 1 and histochemical procedures for mucins (paradoxical concanavalin A, galactose oxidase Schiff and sialidase galactose oxidase Schiff reactions) and proliferation in each compartment evaluated by an immunohistochemical method using bromodeoxyuridine (BrdU) and a monoclonal antibody against BrdU. At the 54th week the number of BrdU-labeled cells per normal pyloric column was significantly (P < 0.05) increased to 10.63/pit after the BII operation, while it diminished to 5.23/pit after RY diversion, this being the same level as with the RY procedure alone. AH maintained a high rate of BrdU incorporation at 12.7% after BII operation, which was also significantly reduced (P < 0.01) to 7.0% by the RY surgery. The intestinal type cell showed highest (22.2%), the surface mucous type cell showed the next (16.5%) and the pyloric gland type cell showed lowest (5.2%) BrdU labeling indices after BII operation. All the cell types in AH showed similar proportional decreases in BrdU incorporation after RY diversion. Thus surgical intervention reverses the cell proliferation caused by bile reflux in the gastric stump.

Exports from the Brazilian automotive sector to the Southern Common Market: Trade diversion or cost reduction?

The automotive sector is one of the sectors in which trade between mercosur countries has grown most strongly. This article examines the possibility that trade diversion occurred in that sector during the period 1991-2010, assuming that product costs fell as a result of market expansion. The analysis is based on the concepts of “cost reduction” and “trade suppression” coined by Corden (1972), which capture the effects of economies of scale. Indices of regional orientation and revealed comparative advantages are used in combination to assess whether the trade bloc is evolving in line with comparative advantages. The results suggest efficiency gains for automotive-sector products, exports of which from Brazil to mercosur grew more vigorously because the expanded and relatively protected market made it possible to exploit the economies of scale that are characteristic of the automotive industry.

Reconstruction of Etna recent flank eruptions for assessing diversion barrier project

The thesis contributed to the volcanic hazard assessment through the reconstruction of some historical flank eruptions of Etna in order to obtain quantitative data (volumes, effusion rates, etc.) for characterizing the recent effusive activity, quantifying the impact on the territory and defining mitigation actions for reducing the volcanic risk as for example containment barriers. The reconstruction was based on a quantitative approach using data extracted from aerial photographs and topographic maps. The approach allows to obtain the temporal evolution of the lava flow field and estimating the Time Average Discharge Rate (TADR) by dividing the volume emplaced over a given time interval for the corresponding duration. The analysis concerned the 2001, 1981 and 1928 Etna eruptions. The choice of these events is linked to their impact on inhabited areas. The results of the analysis showed an extraordinarily high effusion rate for the 1981 and 1928 eruptions (over 600 m^3/s), unusual for Etna eruptions. For the 1981 Etna eruption an eruptive model was proposed to explain the high discharge rate. The obtained TADRs were used as input data for simulations of the propagation of the lava flows for evaluating different scenarios of volcanic hazard and analyse different mitigation actions against lava flow invasion. It was experienced how numerical simulations could be adopted for evaluating the effectiveness of barrier construction and for supporting their optimal design. In particular, the gabions were proposed as an improvement for the construction of barriers with respect to the earthen barriers. The gabion barriers allow to create easily modular structures reducing the handled volumes and the intervention time. For evaluating operational constrain an experimental test was carried out to test the filling of the gabions with volcanic rock and evaluating their deformation during transport and placement.
