A preliminary survey of carrion breeding insects associated with the Eid ul Azha festival in remote Pakistan

In Pakistan, the three days of Islamic festival of Eid ul Azha (Eid) are characterized by millions of livestock sacrifices and availability of countless breeding resources for insects of forensic importance. Thus during Eid, December, 2008, in a Pakistani village observing 70 sacrifices, we examined postmortem insect attractions on various sacrificial products (from 23 animals), i.e., blood pools, meat, hides/skins, bones, offal and real time insect succession on goats' offal at five dump sites. Thirty five insect species were collected from 14 indoor and outdoor sites. Offal at the dump sites attracted most insect species both by taxa and in numbers, followed by hides in the court yards, meat (40-70 kg/animal) in kitchens and blood pools in the court yards. Synanthropic calliphorids and muscids were found to be exclusive indoor "first and only arrivals" in comparison to a diverse array of first day insect arrivals at dump sites including calliphorids, sarcophagids, muscids, sphaerocerids, sepsids, empidids, gryllids and formicids. Though burial is usually considered as a barricade between most insect species and carrion yet dump site A with an early burial but also earliest insect colonization showed the fastest rate of decomposition. No vertebrate scavenging at any of the offal dump sites perhaps showed their private feeding inclination, thus implying that in times of mass slaughters most of the dumped winter carrion products in human vicinities are either consumed by insects and/or are buried. Here we also suggest a high rate of fly dispersal during Eid which if true has consequences for forensic investigations in Muslim populace areas especially during the Eid.     

Comparative Analysis of Insect Succession Data from Victoria (Australia) Using Summary Statistics versus Preceding Mean Ambient Temperature Models

Minimum postmortem interval (mPMI) can be estimated with preceding mean ambient temperature models that predict carrion taxon pre‐appearance interval. But accuracy has not been compared with using summary statistics (mean ± SD of taxon arrival/departure day, range, 95% CI). This study collected succession data from ten experimental and five control (infrequently sampled) pig carcasses over two summers (n = 2 experimental, n = 1 control per placement date). Linear and exponential preceding mean ambient temperature models for appearance and departure times were constructed for 17 taxa/developmental stages. There was minimal difference in linear or exponential model success, although arrival models were more often significant: 65% of linear arrival (r² = 0.09–0.79) and exponential arrival models (r² = 0.05–81.0) were significant, and 35% of linear departure (r² = 0.0–0.71) and exponential departure models (r² = 0.0–0.72) were significant. Performance of models and summary statistics for estimating mPMI was compared in two forensic cases. Only summary statistics produced accurate mPMI estimates.     

Black soldier fly (Diptera: Stratiomyidae) colonization of pig carrion in south Georgia

The black soldier fly, Hermetia illucens (L.), is thought to colonize corpses 20-30 days postmortem. However, recent observations indicate this might not be true for all cases. Therefore, we conducted a study examining colonization by the black soldier fly and other Diptera on pig carrion in a plowed field in southern Georgia from 20 September through 21 February. Our data indicate black soldier flies could colonize a corpse within the first week after death. Knowing this information could prevent a serious mistake in estimating the time at which a corpse is colonized by this species. This study also represents the first record of Chrysomya rufifacies in Georgia.     

The forensic application of allozyme electrophoresis to the identification of blowfly larvae (Diptera: Calliphoridae) in southern Australia

Most known carrion-breeding species of blowflies in southern Australia are of the genus Calliphora. The morphological similarity of the immatures of these species means that correctly identifying them poses a challenge for forensic entomologists. This study investigates the potential of allozyme analysis to assist with this task. Molecular profiles of third-instar larvae and adults representing four of these carrion-breeding species, Calliphora stygia, C. dubia, C. hilli hilli, and C. vicina, were compared at 42 allozyme loci. The two life stages were found to display almost identical allozyme profiles in each species (93% of loci were expressed in both life history stages), enabling the reliable identification of larvae in these four species. Integration of these results with data from a previous study indicates that allozyme analysis would also be suitable for rapid, species-level identification of the larvae of six other carrion-breeding Calliphora species occurring in southern Australia. This is the first report of the application of allozyme data to the identification of forensically important blowflies.     

A cluster analysis of people on Community Treatment Orders in Victoria, Australia

This paper explores the clinical, social and demographic characteristics of 164 people on Community Treatment Orders (CTOs) in one area mental health service in Victoria, Australia. The results of an exploratory cluster analysis are presented to address the question of whether people on Community Treatment Orders can be categorised into statistically reliable, qualitatively distinct groupings. The data are presented in the context of key stakeholder perspectives on the current use and purpose of CTOs. Three stable clusters emerged and each potentially reflects how social dimensions, as well as clinical issues, influence decision making regarding the implementation of CTOs. These findings are important in the context of policy and practice in Victoria, where the use of CTOs is common practice, and orders are generally made for a 12 month period. The potential for improved targeting of CTOs and more specific treatment planning is identified.     

Co-option,coercion and compromise: challenges of restorative justice in Victoria,Australia

Restorative justice (RJ) encompasses a widely diverging set of practices whereby those most affected by crime are encouraged to meet, to discuss the effects of harms caused by one party to another, and to agree upon the best possible redress of harms when appropriate. In its inception in the late 1970s, RJ was conceptualized and developed as an alternative to formal criminal justice practices. Since this time, however, RJ has largely moved from being an alternative to criminal justice practices to an ‘alternative’ practice within criminal justice systems. This institutionalization has resulted in the significant growth of RJ practices, but has also resulted in RJ being used for criminal justice system goals that are at odds with the needs of victims or offenders. This paper examines the use of the Youth Justice Group Conferencing Program in Victoria, Australia. Drawing from interviews with conference conveners, our research highlights problems related to administrative ‘constraints’ and ‘co-options’ in conferencing in terms of referrals, preparation of conference participants, and victim participation. Following presentation of findings, we conclude with a discussion of implications for the use of RJ within a highly institutionalized setting.     

The Quest for Recompense: Claimants' Experience of Medical Negligence Compensation in Victoria,Australia*

This paper reports a study investigating the experiences of people who perceived that they had suffered a health or medical care injury in Victoria, Australia. A particular focus was their experience with the process of seeking compensation. The research strategy involved a preliminary questionnaire and in-depth interviewing of the participants and, where possible, their families. We describe the type of injury reported by the participants, experiences with health care providers and lawyers and attitudes to the current system of compensation. The severity of injury sustained by these participants was often severe, involving permanent incapacity and psychological distress. We conclude that the quest for recompense is fraught with difficulties for claimants. The present system of compensation neither provides adequate financial compensation nor - even where claimants are successful - acknowledgement of the legitimacy of their claim.     

Characteristics and outcome of patients brought to an emergency department by police under the provisions (Section 10) of the Mental Health Act in Victoria,Australia

ObjectiveThe aim of this study is to describe the characteristics and outcome of patients brought to an emergency department by police under Section 10 of Mental Health Act (Victoria, Australia).MethodsRetrospective medical record review. Patients referred under Section 10 provisions treated in calendar year 2009 were identified from ED database. Data collected included demographics, incident details, patient management, final diagnosis and disposition. Primary outcomes of interest were ED diagnosis and disposition. Secondary outcomes were length of stay in ED and use of restraint or sedation.ResultsOne hundred and ninety seven presentations by 164 patients were identified. Patients were predominantly male (58%) with median age of 35 years (IQR 22–44, range 16–69). The most common presenting complaint (65%) was threat of self harm. No sedation or restraint was used in 61%. Sixty seven percent were deemed safe for discharge home while 26% were admitted to a psychiatric ward (equally divided between voluntary and involuntary admission). The predominant discharge diagnosis was self harm ideation or intent (35%). Median ED length of stay was 156 min (inter-quartile range 79–416).ConclusionMost patients brought to ED by police under Section 10 provisions were for threat of self harm and did not require sedation or restraint. The majority are discharged home. Further work exploring less restrictive or traumatic processes to facilitate psychiatric assessment of this group of patients is warranted.

The introduction of CCTV and associated changes in heroin purchase and injection settings in Footscray,Victoria, Australia

Objectives

In June 2011, closed-circuit television (CCTV) was introduced in Footscray (a suburb of Melbourne, Australia) to help deter street-based drug trading. We investigate whether there were subsequent shifts in the settings (e.g., street, house) in which heroin was purchased or injected by people who inject drugs (PWID).

Methods

Using heroin purchase data from the Melbourne Injecting Drug User Cohort Study, multinomial logistic models with fixed effects for CCTV introduction were used to estimate the percentage of: (1) heroin purchased on the street, from mobile dealers and in house settings; and (2) heroin injections occurring in street, car, public toilet, and house settings. Displacement effects were investigated with a logistic model capturing the likelihood of traveling to Footscray to purchase heroin.

Results

Following CCTV introduction, the percentage of heroin injections occurring in public toilet settings decreased by 13 % (95 % CI ?27 %, ?0 %). This was accompanied by a non-significant increase in the percentage of heroin injections in street settings of 23 % (95 % CI ?1 %, +41 %). Changes in other settings were small and non-significant. No suburb displacement effects were found.

Conclusions

The introduction of CCTV in Footscray may have displaced PWID who previously injected heroin in public toilets to street settings. Apart from this, Footscray’s street-based heroin market operates much as it did before CCTV.

     

The forensic examination of structural fires in Victoria,Australia: Decision-making processes and impact on judicial outcomes

There is a body of published research that has evaluated the contribution of forensic science to the criminal justice system, but many disciplines of forensic science remain unexplored in this regard. The aim of this study was to examine the contribution that forensic fire examination services provide to criminal investigations and court processes in arson cases. Forensic fire examination services differ in a number of ways to the disciplines covered in previous research on the impact of forensic evidence on justice outcomes. Forensic fire examinations involve a combination of scene examination and laboratory analyses, and the results can provide critical evidence of whether an incident that has occurred is a criminal offence (i.e. whether a fire has occurred as the result of an act of arson). Forensic fire examination is also a discipline that has faced challenges and undergone development in recent decades regarding its scientific basis and the issue of contextual bias. In this study, data were collated for 273 structural fires that were examined by the forensic fire services in Victoria, Australia. In this jurisdiction, scene and laboratory forensic services are delivered within short time frames with a focus on providing impartial scientific and investigative services to assist criminal investigations conducted by police. The current dataset was highly skewed in terms of criminal justice outcomes and was not suitable for conducting the planned statistical analyses. Nonetheless, the pattern of findings obtained suggested that the inclusion of forensic evidence which supported the prosecution of arson may be associated with an increased likelihood of suspects being charged and defendants found guilty. Examination of the decision-making process of the forensic fire examiners has provided insight into the variety of evidence that is considered by forensic experts in reaching the important conclusion about the origin and cause of structural fires.     

Seasonal structure and dynamics of sarcosaprophagous fauna on pig carrion in a rural area of Cordoba (Argentina): their importance in forensic science

Four experiments, one in each season, were carried out during 2004 in a rural area of Córdoba, central Argentina. Two pigs (Sus scrofa L.), weighing approximately 8 kg each, were used in each of the four experiments. The animals were killed by a sharp blow to the head and immediately placed in an appropriate arthropod trap. One pig was placed in the shade and the other under direct sunlight. This research was conducted to determine the seasonal structure and dynamics of arthropods that constitute the sarcosaprophagous community in a given area of the central region of Argentina. The decomposition process was divided into five stages: fresh, bloated, decay, advanced decay and dry. The duration of each stage varied in different seasons, showing that the temperature and humidity are the most important variables that influence this process. A total of 51,500 adults and 36,909 immature were collected. More than 80% of the specimens collected belong to Insecta, and within this, Diptera were the most abundant order. The flies were mainly represented by adults and immature of the following species: Chrysomya albiceps (Wiedemann) (Calliphoridae), Musca domestica Linnaeus (Muscidae) and Fannia femoralis (Stein) (Fanniidae). Coleoptera were mainly represented by adults and immature of the species Creophilus maxillosus (Linnaeus) (Staphylinidae) and Dermestes maculatus (Geer) (Dermestidae). More than 50% of hymenopteran fauna collected belong to Formicidae. The trophic levels associated with the decomposition of the remains included five categories: necrophagous, parasites and predators of the necrophagous species, omnivores, opportunists and adventives. During faunal succession a strong dominance of the necrophagous species of the family Calliphoridae and Muscidae was observed, mainly during the early stages of decay process in all seasons.     

Radiocarbon dating as tool to assist in triaging cases of unidentified human remains in Victoria,Australia: A case series

In cases where human remains are unidentified because there is no initial identification hypothesis, limited contextual information, and/or poor preservation, radiocarbon (¹⁴C) dating may be a useful tool to further assist with identification. Through measuring the amount of ¹⁴C remaining in organic material, such as bone, teeth, nail, or hair, radiocarbon dating may provide an estimated year of birth and year of death for a deceased person. This information, may assist in, establishing whether a case of unidentified human remains (UHR) is actually of medicolegal significance and therefore, requires forensic investigation and identification. This case series highlights the application of ¹⁴C dating to seven of the 132 UHR cases in Victoria, Australia. Cortical bone was sampled from each case and the level of ¹⁴C was measured to provide an estimated year of death. Four of the seven cases analyzed contained the levels of ¹⁴C consistent with an archeological timeframe, one contained a level of ¹⁴C consistent with a modern (i.e., of medicolegal significance) timeframe, and the results for the remaining two samples were inconclusive. Applying this technique not only reduced the number of UHR cases in Victoria but also has investigative, cultural, and practical implications for medicolegal casework in general.     

Authority to treat: a comparative look at the jurisdiction,practice and procedure of the Supreme Court of Victoria,Children's Court of Victoria and Family Court of Australia in medical matters

The medical treatment of children is a crucial interface of law and medicine. The problems in this emotive area of law are compounded by the current state of the law in Australia which is uncertain and fractured. It is the purpose of this article to examine the jurisdictions of the various courts that stand competent to order that a child undergo medical treatment in circumstances where the child's parents/guardian refuse to provide consent to such treatment. The problems associated with the present system are identified and proposals for the reform of the current system offered.     

Using PMCT of Individuals of Known Age to Test the Suchey–Brooks Method of Aging in Victoria,Australia

The estimation of an individual's age at death plays a critical role in the investigation of unidentified human remains. The Suchey–Brooks method, which involves the analysis of degenerative morphological changes in the pubic symphysis, is currently widely used to estimate age in adults. This study tested the applicability of the Suchey–Brooks method on a contemporary adult Australian (Victorian) subpopulation by observing three‐dimensional volume‐rendered postmortem computed tomographic (PMCT) reconstructions of the pubic symphysis of 204 individuals aged 15–100 years. Results showed the method was reliable for females (85% correct allocations) but not for males (67% correct allocations). It is therefore recommended that extreme caution be used when applying the Suchey–Brooks method for estimating age at death of an individual in this subpopulation from PMCT images. The results suggest further investigation into alternate age estimation methods is required.     

Sketching and validating the location-based services (LBS) regulatory framework in Australia

Location-based services (LBS) are defined as those applications that combine the location of a mobile device associated with a given entity (individual or object) together with contextual information to offer a value-added service. LBS solutions are being deployed globally, and in some markets like Australia, without appropriate regulatory provisions in place. Recent debates in Australia have addressed the need to bridge the gap between technological developments and legal/regulatory provisions. This requires an assessment of the regulatory environment within a given social context such as Australia. The core components of such an investigation include: (a) composing a conceptual framework for analysing regulation of technologies such as LBS, one that is sensitive to public policy themes and challenges, and (b) applying this conceptual framework to the Australian setting in order to sketch and define the components of the present framework, and identify areas for improvement through a process of validation. This paper addresses these aims, demonstrating how the current regulatory framework in Australia is bound by legislation with respect to privacy, telecommunications, surveillance, and national security (that is, anti-terrorism), in addition to a set of industry guidelines for location-service providers (LSPs). The existing Australian framework, however, is lacking in its coverage and treatment of LBS and location data, and does not adequately address the themes and challenges in the defined conceptual framework.     

Reconsidering the southern Europe model: Dowry, women's work and marriage patterns in pre-industrial urban Italy (Turin, second half of the 18th century)

This paper aims to investigate and analyse the impact of the dowry and the endowment system on marriage and household patterns and on the labour market in 18th century Turin. At the same time it enquires into the reliability of the northern/southern Europe pattern for the study of this topic. Two points are developed. Firstly the paper shows that the dowry system coexists with a relatively high age at marriage because of the specific role played by the dowry in Turin society. Indeed, this was not a once-and-for-all established asset but was a negotiable and flexible resource that could be manipulated by the different actors concerned in the endowment. Moreover, the payment did not always take place immediately upon marriage, nor was the money quickly available. At the same time the paper examines the economic role of dowry in Ancien Régime households: by means of a juridical procedure couples could alienate this property, and use or invest it to ensure their well-being and/or their economic situation. Finally, the second part investigates the relationship between the dowry system and the participation of young girls and married women in the local labour market: their significant and crucial presence demonstrates that the dowry and its expectation was not a sufficient incentive to keep them out of the labour market.
