The relationship between emotional state and other variables influencing successful reintegration of ex-prisoners

This study investigated the multiple, complex, dynamic and interactive variables influencing successful reintegration of ex-prisoners, with a particular focus on the role of emotional state in the reintegration process. This involved conduct of a survey to a large group of prisoners approaching release and subsequently following release from prisons in Victoria and Queensland. Participants were 101 adult prisoners who completed a pre-release questionnaire one month prior to their release that focused on prison-related variables, participant background, and anticipated conditions upon release. A post-release questionnaire was administered to the same participants at one to four weeks and three to four months post-release, focusing on the quality of life conditions experienced following release. As well, the Beck Depression Inventory, Beck Anxiety Inventory, and the State-Trait Anger Expression Inventory were completed at each interview. Of interest, was the level and degree of change in prisoner ratings of depression, anxiety, and anger at pre-release and extending over the post-release period. As well, the strength of relationship between emotional state and the main variables influencing reintegration was investigated; that is, the degree to which reintegration variables (such as social support, drug use, post-release program participation, rated health) are associated with depression, anxiety, and anger among ex-prisoners. The report commences with the description of an ecological model of community reintegration that enables the main variables that may influence reintegration of ex-prisoners to be easily conceptualised and understood. A review of the international and Australian literature relevant to community reintegration of ex-prisoners is then presented, consistent with this conceptual framework, with a specific emphasis on the role of emotional state in post-release outcomes for this group. In the second section, the study design and method are described, with the results presented in the third section. The fourth and final section of the report includes a discussion of the results, implications for reintegration theory, and practical implications for promoting successful reintegration of ex-prisoners.

Experience and expression of anger among Australian prisoners and the relationship between anger and reintegration variables

We examined the experience and expression of anger among a group of Australian prisoners prior to and following prison release, as well as the relationship between anger and several reintegration variables. Participants were 79 adult prisoners (54 male, 25 female) who completed the State-Trait Anger Expression Inventory (STAXI-2) 1 month prior to release and again at 1 to 4 weeks and 3 to 4 months post-release. A postrelease questionnaire was also administered at the two postrelease points focusing on the quality of life conditions experienced following release. Mean state and trait anger scores were significantly higher at pre-release than post-release. As well, higher levels of anger expression and anger control were reported at pre-release compared with post-release. Higher age was related to lower state anger at post-release, whereas several variables were related to trait anger at post-release. Theoretical implications for reintegration theory are discussed, together with practical applications.

Examination of the "all hazards" approach to disaster management as applied to field disaster management and pre-hospital care in Australia

Disasters, emergencies, incidents, and major incidents - they all come back to the same thing regardless of what they are called. The common denominator is that there is loss of life, injury to people and animals and damage and destruction of property. The management of such events relies on four phases: 1. Prevention 2. Preparation 3. Response 4. Recovery Each of these phases is managed in a different way and often by different teams. Here, concentration has been given to phases 2 and 3, with particular emphasis on phase 3, Response. The words used to describe such events are often related to legislation. The terminology is detailed later. However, whatever the description, whenever prevention is not possible, or fails, then the need is to respond. Response is always better when the responders are prepared. Training is a major part of response preparation and this book is designed to assist those in the health industry who need to be ready when something happens. One of the training packages for responders is the Major Incident Medical Management and Support (MIMMS) Course and this work was designed to supplement the manual prepared by Hodgetts and Macway-Jones(87) in the UK. Included is what the health services responder, who may be sent to an event in which the main concern is trauma, should know. Concentration is on the initial response and does not deal in any detail with hospital reaction, the public health aspects, or the mental health support that provides psychological help to victims and responders, and which are also essential parts of disaster management. People, in times of disaster, have always been quick to offer assistance. It is now well recognised however, that the 'enthusiastic amateur', whilst being a well meaning volunteer, isn't always what is needed. All too often such people have made things worse and have sometimes ended up as victims themselves. There is a place now for volunteers and there probably always will be. The big difference is that these people must be well informed, well trained and well practiced if they are to be effective. Fortunately such people and organisations do exist. Without the work of the St John Ambulance, the State Emergency Service, the Rural Fire Service the Red Cross and the Volunteer Rescue Association, to mention only a few, our response to disasters would be far less effective. There is a strong history of individuals being available to help the community in times of crisis. Mostly these people were volunteers but there has also always been the need for a core of professional support. In the recent past, professional support mechanisms have been developed from lessons learned, particularly to situations that need a rapid and well organised response. As lessons are learned from an analysis of events, philosophy and methods have changed. Our present system is not perfect and perhaps never will be. The need for an 'all-hazards approach' makes detailed planning very difficult and so there will probably always be criticisms about the way an event was handled. Hindsight is a wonderful thing, provided we learn from it. That means that this text is certainly not the 'last word' and revisions as we learn from experience will be inevitable. Because the author works primarily in New South Wales, many of the explanations and examples are specific to that state. In Australia disaster response is a State, rather than a Commonwealth, responsibility and consequently, and inevitably, there are differences in management between the states and territories within Australia. With the influence of Emergency Management Australia, these differences are being reduced. This means that across state and territory boundaries, assistance is common and interstate teams can be deployed and assimilated into the response rapidly, safely, effectively and with minimum explanation. This text sets out to increase the understanding of what is required, what is in place and how the processes of response are managed. By way of introduction and background, examples are given of those situations that have occurred, or could happen. Man Made Disasters has been divided into two distinct sections. Those which are related to structures or transport and those related directly to people. The first section, Chapter 3, includes: • Transport accidents involving land, rail, sea or air vehicles. • Collapse of buildings for reasons other than earthquakes or storms. • Industrial accidents, including the release of hazardous substances and nuclear events. A second section dealing with the consequences of the direct actions of people is separated as Chapter 4, entitled 'People Disasters'. Included are: • Crowd incidents involving sports and entertainment venues. • Terrorism From Chapter 4 on, the emphasis is on the Response phase and deals with organisation and response techniques in detail. Finally there is a section on terminology and abbreviations. An appendix details a typical disaster pack content. War, the greatest of all man made disasters is not considered in this text.

Comparison of aspirin and indomethacin pre-treatments on the responses to reduced renal artery pressure in conscious dogs

To examine the role of prostaglandins in physiologically induced renin release, we reduced renal artery pressure within the autoregulatory range in chronically instrumented conscious dogs with aspirin, indomethacin or no pre-treatment. In untreated dogs, reduction of renal artery pressure to 60 mmHg for 90 min produced rises in plasma renin activity (+ 5.4 +/- 1.0 ng ml.-1 hr-1) and mean arterial pressure (+ 17 +/- 2 mmHg) without significant effect on renal blood flow (n = 13). Aspirin pre-treatment (2 X 25-40 mg kg-1 orally) had no effect on the renin, arterial pressure or renal blood flow responses to renal artery pressure reduction (n = 7). In contrast, indomethacin pre-treatment (2 X 2-3 mg kg-1 orally) significantly lessened the increase in plasma renin activity during reduced renal artery pressure (+ 2.0 +/- 0.3 ng ml.-1 hr-1, n = 11). The relative effectiveness of aspirin and indomethacin in inhibiting prostaglandin production in the kidney was then tested in separate experiments by measuring the renal blood flow responses to renal artery injections of arachidonate (5-200 micrograms kg-1). In the doses used above, aspirin markedly attenuated the blood flow response to arachidonate but indomethacin had almost no effect. Both aspirin and indomethacin abolished the hypotensive effect of intravenous arachidonate (0.5 mg kg-1). These results tentatively suggest that indomethacin may not effectively inhibit renal prostaglandin production in conscious dogs at the doses used in these experiments. Thus the reduced renin release in response to lowered renal artery pressure in indomethacin pre-treated dogs may have been due to another, non-prostaglandin action of indomethacin. The results from the aspirin pre-treated dogs suggest that prostaglandins are not involved in the release of renin in response to reduced renal artery pressure in conscious dogs.

Discovery of the Early Ordovician strata in Xianza County, Tibet and its significance

There is no any sediments contain fossils which formed earlier than Middle Ordovician in northern Tibet yet. It is very important whether have developed the Cambrian to Early Ordovician sedimentary strata. During geological mapping of Xainza County in 2000, Tetragraptus approximatus, the typical one of graptolite belts which cosmepolitically distributed in the Arenigian of Early Ordovician, was collected from the so-call Pre-Sinian Nianqingtanggula Group. So there is developped the Early Ordovician sediments and we have established Zakang Formation and Taduo Formation which perfected the Plaeozoic sequences in northern Tibet. According to these, we can realize tectonic control, palaeogeographrc pattern as well as palaeobiogeographic distribution of the Qinghai-Tibet Plateau in the early Paleozoic and also provided the materials to the cosmepolitical biostratigraphic contrast.

Drug release rate and anti-microbial effect of controlled-diffusion biopolymer membranes

In this study, a series of fibrous membranes made from cellulose acetate (CA) and polyester urethane (PEU) by co-electrospining or blend-electrospining were evaluated for drug release kinetics, in vitro anti-microbial activity and in vivo would healing performance when used as wound dressings. To stop common clinical infections, an antibacterial agent, Polyhexamethylene Biguanide (PHMB) was incorporated into e-spun fibres. The presence of CA in the wound healing membrane was found to improve hydrophilicity and permeability to air and moisture. The in vivo tests indicated that the addition of PHMB and CA considerably improved the wound healing efficiency. CA fibres became slightly swollen upon contacting with the wound exudates. It can not only speed up the liquid evaporation but also create a moisture environment for wound recovery. The drug release dynamics of membranes was controlled by the structure of membranes and component rations within membranes. The lower ration of CA:PEU retained the sound mechanical properties of membranes, and also reduced the boost release effectively and slowed down diffusion of antibacterial agent during in vitro tests. The controlled-diffusion membranes exert long-term anti-infective effect.

RAFT controlled synthesis of graphene/polymer hydrogel with enhanced mechanical property for pH-controlled drug release

A pH-sensitive, mechanically strong and thermally stable graphene/poly (acrylic acid) (graphene/PAA) hydrogel was prepared via reversible addition fragmentation transfer (RAFT) polymerizations in the presence of a cross-linking agent. The RAFT agent was covalently coupled onto graphene basal planes via an esterification reaction, with benzoic acid functionalities pre-attached on graphene with its aryl diazonium salt precursor. AFM and SEM analysis revealed the successful preparation of single layered graphene sheets and graphene/polymer hydrogels with pH controlled porous structures. Attenuated total reflection infrared (ATR-IR) and thermogravimetric analyzer (TGA) verified the successful stepwise preparation of graphene/PAA hydrogel. This graphene/PAA hydrogel was pH-sensitive and more mechanically elastic than the PAA hydrogel prepared without graphene. The pH sensitivity of the hydrogel was further utilized for controlled drug release. Doxorubicin was chosen as a model drug and loaded into the hydrogels. The drug loading and release experiment indicated that this hydrogel can be used to efficiently control drug release in the intestine environment (pH = 7.4), better than release in a more acidic environment.© 2013 Elsevier Ltd.

Sodium bicarbonate infusion in patients undergoing orthotopic liver transplantation: a single center randomized controlled pilot trial

BACKGROUND: Liver transplantation-associated acute kidney injury (AKI) carries significant morbidity and mortality. We hypothesized that sodium bicarbonate would reduce the incidence and/or severity of liver transplantation-associated AKI. METHODS: In this double-blinded pilot RCT, adult patients undergoing orthotopic liver transplantation were randomized to an infusion of either 8.4% sodium bicarbonate (0.5 mEq/kg/h for the first hour; 0.15 mEq/kg/h until completion of surgery); (n = 30) or 0.9% sodium chloride (n = 30). Primary outcome: AKI within the first 48 h post-operatively.RESULTS: There were no significant differences between the two treatment groups with regard to baseline characteristics, model for end-stage liver disease and acute physiology and chronic health evaluation (APACHE) II scores, and pre-transplantation renal function. Intra-operative factors were similar for duration of surgery, blood product requirements, crystalloid and colloid volumes infused and requirements for vasoactive therapy. Eleven patients (37%) in the bicarbonate group and 10 patients (33%) in the sodium chloride group developed a post-operative AKI (p = 0.79). Bicarbonate infusion attenuated the degree of immediate post-operative metabolic acidosis; however, this effect dissipated by 48 h. There were no significant differences in ventilation hours, ICU or hospital length of stay, or mortality. CONCLUSIONS: The intra-operative infusion of sodium bicarbonate did not decrease the incidence of AKI in patients following orthotopic liver transplantation.
