Sentencing law and practice impacts on fundamental individual interests, both from the perspective of offenders and victims. It also affects community safety and security The scope of sentencing law and its principal objectives are broadly similar throughout Australia. However, there are many important differences, especially in relation to sentencing practice, with some jurisdictions appearing to impose considerably heavier penalties for certain offence types. This article argues that uniform sentencing law should be implemented throughout Australia. The likely benefits would extend beyond achieving greater consistency in sentencing outcomes. A move toward uniform national sentencing laws would provide the catalyst for an objective, evidence-based review of sentencing policy and practice, thereby providing a vehicle for harmonising the law with a wealth of empirical data regarding the objectives that can be achieved through a system of state-imposed sanctions. It would also present a meaningful opportunity for a normative assessment of the justifiable operation of sentencing law. The main impediment to uniform sentencing laws is likely to come from state and territory governments seeking to maintain control over this often socially controversial area as a means of securing and maintaining community support. However, this obstacle is not necessarily insurmountable. It is not clear whether sentencing policy is, in fact, a main driver of voter preferences. Some politicians may prefer to have ·national uniformity' as a buffer to counteract reflexive calls for tougher sentencing that often occur following particularly serious crimes or seemingly light sentences handed down by courts.

Cost-effective, sustainable strategies are urgently required to curb the global obesity epidemic. To date, fiscal policies such as taxes and subsidies have been driven largely by imperatives to raise revenue or increase supply, rather than to change population behaviours. This paper reviews the economic evaluation literature around the use of fiscal policies to prevent obesity. The cost-effectiveness literature is limited, and more robust economic evaluation studies are required. However, uncertainty and gaps in the effectiveness evidence base need to be addressed first: more studies are needed that collect ‘real-world’ empirical data, and larger studies with more robust designs and longer follow-up timeframes are required. Reliability of cross-price elasticity data needs to be investigated, and greater consideration given to moderators of intervention effects and the sustainability of outcomes. Economic evaluations should adopt a societal perspective, incorporate a broader spectrum of economic costs and consider other factors likely to affect the implementation of fiscal measures. The paucity of recent cost-effectiveness studies means that definitive conclusions about the value for money of fiscal policies for obesity prevention cannot yet be drawn. However, as in other public health areas such as alcohol and tobacco, early indications are that population-level fiscal policies are likely to be potentially effective and cost-saving.

This paper focuses on effective learning spaces in contemporary higher education. Drawing on empirical data from a qualitative study of international students’ experience of blended learning programs conducted in three computing courses in two Australian universities, a range of issues and challenges are reported. Three pedagogical principles are then presented that respond to these challenges: 1. Enabling learners – learning how to learn in virtual learning spaces; 2. Programming for flexible learning – learning how to manage virtual learning environments; and, 3. Transforming learning – learning how to capitalise on the affordances of new technologies. The pedagogical principles are presented together with examples of types of practices that they support.

Teaching International Students in Vocational Education: New pedagogical approaches is designed to support vocational education teachers in both addressing the distinctive learning characteristics of international students and preparing domestic students for global skills mobility in the ‘Asian Century’.

Well-grounded in theories about teaching and learning in vocational and international education, and supported by empirical data drawn from interviews with teachers and program managers, the book expounds several evidence-based, highly effective, pedagogical approaches within the context of competency-based training. These include:
- the intercultural approach
- the Ubuntu approach
- the language and vocational learning integration approach
- the perspective transformation approach
- the value-added approach
- work-based learning
- flexible and divergent pedagogy.

These approaches focus on developing the learner’s ability to consider the broader issues in an intercultural context, to capitalise on prior experience and to adapt vocational skills to workplace settings transnationally. The underpinning theory is brought to life with real-world exemplars, ‘Implications for Practice’, quotes and insights from teachers, as well as reflective questions throughout the book.

International VET students have divergent, shifting and in some cases multiple purposes for undertaking their VET courses. Students' motives may be instrumental and/or intrinsic and can include obtaining permanent residency, accumulating skills that can secure good employment, gaining a foothold that leads to higher education, and/or personal transformation. Moreover, students' study purposes and imagining of acquired values are neither fixed nor unitary. They can be shaped and reshaped by their families and personal aspirations and by the social world and the learning environment with which they interact. We argue that, whatever a student's study purpose, s/he needs to engage in a learning practice and should be provided with a high quality education. Indeed, we insist this remains the case even if students enroll only in order to gain the qualifications needed to migrate. The paper details the association between migration and learning, and argues that the four variations emerging from the empirical data of this study that centre on migration and skills' accumulation better explain this association than does the 'international VET students simply want to migrate' perspective. We conclude with a discussion of why the stereotype that holds VET international students are mere 'PR hunters' is unjust and constitutes a threat to the international VET sector.

Since the US-led invasion of Iraq in 2003, this country has witnessed an unprecedented sectarian atmosphere. The newly installed political system by the US has institutionalised the ethno-sectarian nature of the political “democratic” scene and the influx of al-Qaida and other militia were exacerbating the violent context. The post- invasion formed State apparatus has been crippled and not been capable of taking control, enforcing law, restoring order and establishing sustainable reconciliation. Within this context, tribes have emerged as a powerful disciplinary social structure that is capable of conflict management and national reconciliation. Based on empirical data collected from Iraq, this paper discusses the roles of Iraqi tribes in peaceful reconciliation processes. It further engages with the tribal discourses and communication methods used in this process to contribute to bringing stability to the country. Tribes have applied different modes of communications and methods of conflict management at different individual, communal and national levels.

Although long-distance transport of marine organisms is constrained by numerous oceanic and biological factors, some species have evolved life-histories reliant on such movements. We examine the factors that promote long-distance transport in a transoceanic migrant, young loggerhead sea turtles (Caretta caretta), from the southeastern U.S. Empirical data from near-surface buoys and simulations in two ocean circulation models indicated that passive drifters are often retained for long periods shoreward of oceanic fronts that delineate coastal and offshore waters. Further simulations revealed that offshore swimming aided newly hatched turtles in moving past fronts and increased turtles’ probability of survival, reaching distant foraging grounds, and encountering favorable temperatures. Swimming was most beneficial in regions that were more favorable under scenarios assuming passive drift. These results have broad implications for understanding the movement processes of many marine species, highlighting likely retention of more planktonic species and potential for dispersal in more nektonic species.

An important task in multiple-criteria decision making is how to learn the weights and parameters of an aggregation function from empirical data. We consider this in the context of quantifying ecological diversity, where such data is to be obtained as a set of pairwise comparisons specifying that one community should be considered more diverse than another. A problem that arises is how to collect a sufficient amount of data for reliable model determination without overloading individuals with the number of comparisons they need to make. After providing an algorithm for determining criteria weights and an overall ranking from such information, we then investigate the improvement in accuracy if ranked 3-tuples are supplied instead of pairs. We found that aggregation models could be determined accurately from significantly fewer 3-tuple comparisons than pairs. © 2013 IEEE.

 Clinical studies indicate that children who engage in coercive or aggressive sexual acts are more likely to come from conditions of developmental adversity. Broadly speaking, the context of risk for children engaging in these behaviours aligns with particular indicators of social exclusion; geographic disadvantage, compromised family functioning and poverty. Children from such conditions of adversity are thought to be doubly compromised, as the context of risk that gave rise to the behaviours may also compromise families’ engagement with specialised therapeutic services to modify a child’s behaviours. In the absence of empirical data on the prevalence of problem sexual behaviours in Australia, this paper suggests that that scholarship and data collection underpinning the social inclusion policy agenda may inform the targeted delivery of secondary prevention strategies for children most at risk of engaging in problem sexual behaviours.

This study assesses the effects of mentoring and organisational ethical climate (OEC) on the organisational and professional commitment (PC) of early career accountants (ECAs) (i.e. accounting graduate recruits with three or less years of working experience). The empirical data are based on a questionnaire survey from 86 ECAs in Australian public accounting firms, and hypothesis testing utilises partial least squares analysis. Our results indicate when a career development style of mentoring is adopted there is greater organisational as well as PC. By contrast, a social support mentoring style has no significant impact on organisational commitment (OC) and a negative effect on PC. Further, our data also reveal OEC to be positively associated with OC, and OC in turn having a positive impact on PC. The results imply that fostering a career-focused mentoring environment and an OEC can increase an ECA's OC and PC. These results have various implications for human resource management at both the accounting firm and professional levels.

   Although there is an under-acknowledgement of the issue in Australia there is a large body of international scholarship on juveniles who exhibit sexually violent or coercive behaviours toward other juveniles. Research undertaken in the United States and the United Kingdom emphasises options for clinical treatment, the logistics of coordinating multi agency response, and the causes and correlatives for coercive sexual behaviours in adolescents. Much of this literature has tended to focus on adolescents and there is an urgent need for increased studies on young children engaging in problem sexual behaviour.

   The smaller body of work published in Australia also favours adolescents rather than children with much of this work heavily influenced by international clinical studies. There are, however, a handful of reports based on Australian practitioner data that do focus on young children who engage in problem sexual behaviour. This literature surveys and evaluates the very limited number of existing therapeutic programs in Australia, and provides interview data with practitioners working with children exhibiting problem sexual behaviour. In the main, this research reinforces the findings of the internationa scholarship, both in terms of the contributing factors to problem sexual activity in children, but also in terms of the need for multi-faceted and contextually based cognitive behavioural therapeutic programs in response. More importantly, this burgeoning field of study indicates how far we have to go both in understanding the extent of the problem in Australia and in fashioning appropriate programs for prevention and intervention. Dr Joe Tucci is Chief Executive Officer of the Australian Childhood Foundation (ACF), an organisation that has taken a lead in responding to childhood problem sexual behaviour. Tucci et al., (2006) claim an urgent need for investment in a dedicated research and response agenda (Staiger et al., 2005b). To effectively address this issue researchers and practitioners require comprehensive empirical data on problem sexual behaviour in children across all sectors of Australian society, including Indigenous communities.

Purpose: The purpose of this paper is to discuss how decisions regarding organisational flexibility can be improved through targeted resource allocation, by focusing on the supply chain's level of uncertainty exposure. Specifically, the issue of where and in what ways flexibility has been incorporated across the organisation's supply chain is addressed. Design/methodology/approach: A two-phase methodology design based on literature review and case study was used. Using 83 journal articles in the areas of uncertainty and flexibility an analytical process for assessing uncertainty-flexibility mismatches was developed. Furthermore, results from ten interviews with senior/middle managers within the Australian manufacturing sector were used to provide preliminary insights on the usefulness and importance of the analytical process and its relationship with organisational practice. Findings: The paper emphasises the importance of having a systematic and encompassing view of uncertainty-flexibility mismatches across the supply chain, as well as the significance of socio-technical engagement. The paper both conceptually and empirically illustrates how, using a structured analytical process, flexibility requirements across the supply, process, control and demand segments of a supply chain might be assessed. A four-step analytical process was accordingly developed and, its application, usefulness and importance discussed using empirical data. Practical implications: The analytical process presented in this paper can assist managers to obtain a comprehensive overview of supply chain flexibility when dealing with situations involving uncertainty. This can facilitate and improve their decision-making with respect to prioritising attention on identified flexibility gaps in order to ensure stability of their performance. Originality/value: The paper presents a supply chain-wide discussion on the difficulties that uncertainty brings to organisations, and how organisational flexibility might serve to moderate those challenges for supply chain management. It discusses how to identify the flexibility gap and proposes an original analytical process for systematic assessment of uncertainty-flexibility mismatches. © Emerald Group Publishing Limited.

Complexity is increasingly the hallmark in environmental management practices of sandy shorelines. This arises primarily from meeting growing public demands (e.g., real estate, recreation) whilst reconciling economic demands with expectations of coastal users who have modern conservation ethics. Ideally, shoreline management is underpinned by empirical data, but selecting ecologically-meaningful metrics to accurately measure the condition of systems, and the ecological effects of human activities, is a complex task. Here we construct a framework for metric selection, considering six categories of issues that authorities commonly address: erosion; habitat loss; recreation; fishing; pollution (litter and chemical contaminants); and wildlife conservation. Possible metrics were scored in terms of their ability to reflect environmental change, and against criteria that are widely used for judging the performance of ecological indicators (i.e., sensitivity, practicability, costs, and public appeal). From this analysis, four types of broadly applicable metrics that also performed very well against the indicator criteria emerged: 1.) traits of bird populations and assemblages (e.g., abundance, diversity, distributions, habitat use); 2.) breeding/reproductive performance sensu lato (especially relevant for birds and turtles nesting on beaches and in dunes, but equally applicable to invertebrates and plants); 3.) population parameters and distributions of vertebrates associated primarily with dunes and the supralittoral beach zone (traditionally focused on birds and turtles, but expandable to mammals); 4.) compound measurements of the abundance/cover/biomass of biota (plants, invertebrates, vertebrates) at both the population and assemblage level. Local constraints (i.e., the absence of birds in highly degraded urban settings or lack of dunes on bluff-backed beaches) and particular issues may require alternatives. Metrics - if selected and applied correctly - provide empirical evidence of environmental condition and change, but often do not reflect deeper environmental values per se. Yet, values remain poorly articulated for many beach systems; this calls for a comprehensive identification of environmental values and the development of targeted programs to conserve these values on sandy shorelines globally.

There has been a considerable increase in the penalties for drug trafficking following the United Nations Single Convention on Narcotic Drugs 1961, over fifty years ago. In many parts of the world, the sanctions are as severe as those for homicide and rape. This penalty escalation is at odds with the counter movement to decriminalise illicit drugs. Drug supplying is the only serious crime where there are widespread moves to decriminalize the main outcome of the crime – the use illicit drugs. This paper explores this paradox. It also examines the rationales for the increasingly harsh penalties for drug suppliers. We conclude that while there is no conclusive argument in favour of the decriminalizing drugs, the weight of empirical data does not establish any concrete benefits stemming from severe penalties for serious drug offenses. In particular, there is no correlation between longer prison terms for drug offenders and a reduction in the availability and use of drugs. We propose that the penalties for drug offenses should be reduced considerably. There is no useful objective that can be achieved by a twenty-five-year term of imprisonment that cannot be achieved by a term of five to ten years. A more measured sentencing response to serious drug offense penalties would make sentencing fairer and enable billions of dollars currently directed to imprisonment to be spent on more pressing community needs.
