Issues in Green Criminology: confronting harms against environments, humanity and other animals aims to provide, if not a manifesto, then at least a significant resource for thinking about green criminology, a rapidly developing field. It offers a set of specially written introductions and a variety of current and new directions, wide-ranging in scope and international in terms of coverage and contributors. It provides focused discussions of current and cutting edge issues that will influence the emergence of a coherent perspective on green issues. The contributors are drawn from the leading thinkers in the field. The twelve chapters of the book explore the myriad ways in which governments, transnational corporations, military apparatuses and ordinary people going about their everyday lives routinely harm environments, other animals and humanity. The book will be essential reading not only for students taking courses in colleges and universities but also for activists in the environmental and animal rights movements. Its concern is with an ever-expanding agenda - the whys, the hows and the whens of the generation and control of the many aspects of harm to environments, ecological systems and all species of animals, including humans. These harms include, but are not limited to, exploitation, modes of discrimination and disempowerment, degradation, abuse, exclusion, pain, injury, loss and suffering. Straddling and intersecting these many forms of harm are key concepts for a green criminology such as gender inequalities, racism, dominionism and speciesism, classism, the north/south divide, the accountability of science, and the ethics of global capitalist expansion. Green criminology has the potential to provide not only a different way of examining and making sense of various forms of crime and control responses (some well known, others less so) but can also make explicable much wider connections that are not generally well understood. As all societies face up to the need to confront harms against environments, other animals and humanity, criminology will have a major role to play. This book will be an essential part of this process.

Whilst alcohol is a common feature of many social gatherings, there are numerous immediate and long-term health and social harms associated with its abuse. Alcohol consumption is the world’s third largest risk factor for disease and disability with almost 4% of all deaths worldwide attributed to alcohol. Not surprisingly, alcohol use and binge drinking by young people is of particular concern with Australian data reporting that 39% of young people (18-19yrs) admitted drinking at least weekly and 32% drank to levels that put them at risk of alcohol-related harm. The growing market penetration and connectivity of smartphones may be an opportunities for innovation in promoting health-related self-management of substance use. However, little is known about how best to harness and optimise this technology for health-related intervention and behaviour change. This paper explores the utility and interface of smartphone technology as a health intervention tool to monitor and moderate alcohol use. A review of the psychological health applications of this technology will be presented along with the findings of a series of focus groups, surveys and behavioural field trials of several drink-monitoring applications. Qualitative and quantitative data will be presented on the perceptions, preferences and utility of the design, usability and functionality of smartphone apps to monitoring and moderate alcohol use. How these findings have shaped the development and evolution of the OnTrack app will be specifically discussed, along with future directions and applications of this technology in health intervention, prevention and promotion.

Objective: To measure alcohol-related harms to the health of young people presenting to emergency departments (EDs) of Gold Coast public hospitals before and after the increase in the federal government "alcopops" tax in 2008. Design, setting and participants: Interrupted time series analysis over 5 years (28 April 2005 to 27 April 2010) of 15-29-year-olds presenting to EDs with alcohol-related harms compared with presentations of selected control groups. Main outcome measures: Proportion of 15-29-year-olds presenting to EDs with alcohol-related harms compared with (i) 30-49-year-olds with alcohol-related harms, (ii)15-29-year-olds with asthma or appendicitis, and (iii) 15-29-yearolds with any non-alcohol and non-injury related ED presentation. Results: Over a third of 15-29-year-olds presented to ED with alcohol-related conditions, as opposed to around a quarter for all other age groups. There was no significant decrease in alcohol-related ED presentations of 15-29-year-olds compared with any of the control groups after the increase in the tax. We found similar results for males and females, narrow and broad definitions of alcoholrelated harms, under-19s, and visitors to and residents of the Gold Coast. Conclusions: The increase in the tax on al copops was not associated with any reduction in alcohol-related harms in this population in a unique tourist and holiday region. A more comprehensive approach to reducing alcohol harms in young people is needed.

Background A brief intervention, conducted in the acute setting care setting after an alcohol-related injury, has been reported to be highly beneficial in reducing the risk of re-injury and in reducing subsequent level of alcohol consumption. This project aimed to understand Australasian Oral and Maxillofacial Surgeons' attitudes, knowledge and skills in terms of alcohol screening and brief intervention within acute settings for patients admitted with facial trauma. Materials and Methods A web-based survey was made available to all members (n=200-250) of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons (ANZAOMS), promoted through a number of email bulletins sent by the Association to all members. Implied consent is assumed for participants who complete the online survey. The survey explored their current level of involvement in treating patients with alcohol-relatd facial trauma, as well as their knowledge of and attitudes towards alcohol screening and brief intervention. The survey also explored their willingness for further training and involvement in implementing a SBI program. Parts of the survey were based on a hypothetical case with facial injury and drinking history which was presented to the participants and the participants were asked to give their response to this scenario. Results A total of 58 surgeons completed the on-line survey. 91% of surgeons surveyed were males and 88% were consultant surgeons. 71% would take alcohol history; 29% would deliver a brief alcohol intervention and 14% would refer the patients to an alcohol treatment service or clinician. 40% agreed to have adequate training in managing patients with alcohol-related injuries, while 17% and 19% felt they had adequate time and resources. 76% of surgeons reported the need for more information on where to refer patients for appropriate alcohol treatment. Conclusion The study findings confirm the challenges and barriers to implementing brief alcohol intervention in current practice. There are service gaps that exist, as well as opportunities for training.

Bone-anchored prostheses are increasingly acknowledged as viable alternative method of attachment of artificial limb compared to socket-suspended prostheses. To date, a few osseointegration fixations are commercially available. Several devices are at different stages of development particularly in Europe and the US. Clearly, the current momentum experienced worldwide is creating a need for a standardized evaluation framework to assess the benefits and safety of each procedure.

Unlicensed driving is a serious problem in many countries, despite ongoing improvements in traffic law enforcement practices and technology. The term "unlicensed driver" is generally used to refer to people who drive or ride a motor vehicle without a valid driver's licence, including those who: • Have let their licence expire, • Have been disqualified or suspended from driving, • Hold an inappropriate licence for the class of vehicle they drive, • Drive outside the restrictions of a special licence, • Don’t currently hold a licence, or • Have never held a licence (Watson, 2003, 2004a)...

Background Hepatitis C (HCV) was described as a “viral time bomb” due to its prevalence and potential for causing serious, life-threatening complications. The Australian’s National Hepatitis C Strategy calls for a coordinated, evidence-based approach to testing, management, care and support of HCV. This review aimed to systematically and comparatively appraise existing international HCV clinical guidelines. Methods A systematic search of bibliographic databases and reference lists from selected papers were the source of data. Inclusion criteria were latest clinical guidelines as defined by Institute of Medicine, published in English, between January 2002 and November 2014. Quality of the guidelines was independently assessed using the iCAHE instrument. Results Twenty-eight international clinical practice guidelines were included. The majority of the international guidelines were based on the same primary studies however clinical recommendations on pre- and in-treatment assessments, choice of pharmaceuticals, and dosages and duration of the same pharmaceutical agents varied considerably. This diversity was beyond what would be considered reasonable practice context variations. Furthermore, there is limited guidance on post-treatment surveillance and care. Conclusions/implications There is a need for a harmonised international consensus on the clinical management of HCV. Key message A lack of consistency among international HCV clinical guidelines may impede effective and efficient patient care.

In this paper, a rapid, high efficient, sensitive and inexpensive approach based on a combination of simple ultrasonic extract and capillary electrophoresis (CE) separation with electrochemical detection (ED), is described to identify herbs by comparing their CE-ED profiles (namely, CE-ED electropherograms). The proposed method takes advantage of ultrasmall sample volume, low consumption of organic solvent, simple sample pretreatment and easy cleanup procedure. It was applied to analyze the CE-ED profiles of stems of herb Acanthopanax senticosus (Rupr. Et Maxim.) Harms from different sources and different parts (roots, rhizomes, stems and leaves) of this herb. By comparing peak number, peak height and peak height ratio, we found that the CE-ED profiles showed big differences for the herbs from the different sources and the different parts of this herb. In addition, the distribution of bioactive compounds (isofraxidin, rutin and chlorogenic acid) in the different parts of this herb and their content variations affected by the source were studied with the CE-ED method. Based on their own unique CE-ED profiles, these herbs from the different sources and the different parts of this herb could be easily distinguished. Therefore, the proposed approach could be used as a rapid, high efficient and sensitive method for the identification of herbal medicines.

Eighteen triterpenoidic saponins in crude extracts from leaves of Acanthopanax senticous Harms have been investigated by electrospray ionization multi-stage tandem mass spectrometry and high-resolution mass spectrometry. In ESI-MS spectra, predominant [M + Na](+) ions in the positive ion mode have been observed for molecular mass information. Meanwhile, specific structural correlations between these ions are firstly found. The 18 peaks (ions) can be classified into three groups (group D, E, and F with mass increase) with each group including six peaks. There is a mass difference of 132 Da between group D and E for each corresponding peak in turn (for example peak 1 to peak 7), indicating one more pentose residue was attached to saponins in group E than those corresponding in group D. The mass difference of 146 Da between group E and F implies one more deoxy-hexose attached to saponins in group F than those corresponding in group E. The structural correlations of the corresponding ions are confirmed by tandem mass spectrometry and high-re solution mass spectrometry. These structural features can not only facilitate the rapid characterization of the native known saponins in crude plant extracts, thus avoiding tedious derivation and separation of saponins, but also help find novel compounds of the same type in a specific medicinal plant.

Using electrospray tandem mass spectrometry (ESI-MSn), the flavonoids obtained from leaves in Acanthopanax Senticosus Harms were analyzed. The typical colorimetric method and the ultroviolet spectrophotometry were also utilized for the determination of the content of total flavonoids. The analytical results showed that there was quercetin as well as its derivatives in leaves of acanthopanax senticosus harms and their content was as high as 37.25%.

Four flavonoids from leaves of Acanthopanax Senticosus Harms were observed in negative ion mode in the electrospray mass spectra. Two of them were further isolated and identified as quercitrin (quercetin-3-O-alpha-L-rhamnoside) and hyperin (quercetin-3-O-beta-D-galactoside) on the basis of MS' and NMR data. The other two compounds in the mixtures were tentatively established as quercetin and rutin (quercetin-3-O-rutinoside) in terms of their electrospray tandem mass spectrometry (ESI-MSn) data. Three of the four flavonoids (excluding hyperin) haven't been reported in this plant before.

Three known flavonoids, quercetin, quercitrin (quercetin-3-0-rhamnoside) and rutin (quercetin-3-0-rutinoside), have been identified for the first time in the leaves of Acanthopanax senticosus Harms by using electrospray tandem mass spectrometry techniques (ESI-MSn). The flavonoid hyperin (quercetin-3-0-beta-galactoside), already known to be present, was also investigated. The diagnostic fragment ions of the aglycone quercetin were obtained in the ESI-MSn experiments, and a fragmentation mechanism proposed.
