This collection explores male sex work from an array of perspectives and disciplines. It aims to help enrich the ways in which we view both male sex work as a field of commerce and male sex workers themselves. Leading contributors examine the field both historically and cross-culturally from fields including public health, sociology, psychology, social services, history, filmography, economics, mental health, criminal justice, geography, and migration studies, and more. Synthesizing introductions by the editors help the reader understand the implications of the findings and conclusions for scholars, practitioners, students, and members of the interested/concerned public.

(Sub)Urban Sexscapes brings together a collection of theoretically-informed and empirically rich case studies highlighting the contemporary and historical geographies and regulation of the commercial sex industry. Contributions in this edited volume examine the spatial and regulatory contours of the sex industry from a range of disciplinary perspectives—urban planning, urban geography, urban sociology, and, cultural and media studies—and geographical contexts—Australia, the UK, US and North Africa. In overall terms, (Sub)urban Sexscapes highlights the mainstreaming of commercial sex premises—sex shops, brothels, strip clubs and queer spaces—and products—sex toys, erotic literature and pornography—now being commonplace in night time economy spaces, the high street, suburban shopping centres and the home. In addition, the aesthetics of commercial and alternative sexual practices—BDSM and pornography—permeate the (sub)urban landscape via billboards, newspapers and magazines, television, music videos and the Internet. The role of sex, sexuality and commercialized sex, in contributing to the general character of our cities cannot be ignored. In short, there is a need for policy-makers to be realistic about the historical, contemporary and future presence of the sex industry. Ultimately, the regulation of the sex industry should be informed by evidence as opposed to moral panics.

Critical stage in open-pit mining is to determine the optimal extraction sequence of blocks, which has significant impacts on mining profitability. In this paper, a more comprehensive block sequencing optimisation model is developed for the open-pit mines. In the model, material characteristics of blocks, grade control, excavator and block sequencing are investigated and integrated to maximise the short-term benefit of mining. Several case studies are modeled and solved by CPLEX MIP and CP engines. Numerical investigations are presented to illustrate and validate the proposed methodology.

This article examines the legal principles governing the statutory work health and safety general duties of principals who engage expert contractors to carry out work beyond the expertise of the principal. The article examines recent case law in which superior courts accepted the principal’s argument that the engagement of the expert contractor was sufficient to discharge the principal’s statutory work health and safety general duty. It then reframes the debate within the principles of systematic work health and safety management, and key provisions in the harmonised Work Health and Safety Acts—the primary duty of care; the key underpinning principles; the positive and proactive officer’s duty; and the horizontal duty of consultation, cooperation and coordination. It argues that it is likely that courts examining the issue of the principal’s work health and safety obligations under the harmonised Work Health and Safety Acts will require principals to do more to actively manage the work of expert contractors to ensure the health and safety of all workers and others potentially affected by the work.

The employment and work experiences of mothers who care for young children with special health care needs is the focus of this study. It addresses a gap in the research literature, by providing an understanding of how mothers’ caring role may affect employment conditions, family life, and financial well-being. Quantitative data are drawn from Growing Up in Australia: The Longitudinal Study of Australian Children. The current study employs a matched case–control methodology to compare the experiences of a group of 292 mothers whose children (aged 4-5 years) with long-term special health care needs with those mothers whose children were typically developing. There were few differences between the two groups with regard to job characteristics and job quality. There were significant differences between the two groups with regard to work–family balance. Fewer mothers with children with special health care needs reported work having a positive effect on family functioning.

There is a great deal of research that examines flexible working arrangements, but this work tends to be concentrated in large organisations. This research examines the approach taken to flexible working arrangements in five small community based, not for profit organisations. We present three propositions that aim to understand the constraints and the characteristics of flexible work in this rarely studied sector.

Transit passenger market segmentation enables transit operators to target different classes of transit users for targeted surveys and various operational and strategic planning improvements. However, the existing market segmentation studies in the literature have been generally done using passenger surveys, which have various limitations. The smart card (SC) data from an automated fare collection system facilitate the understanding of the multiday travel pattern of transit passengers and can be used to segment them into identifiable types of similar behaviors and needs. This paper proposes a comprehensive methodology for passenger segmentation solely using SC data. After reconstructing the travel itineraries from SC transactions, this paper adopts the density-based spatial clustering of application with noise (DBSCAN) algorithm to mine the travel pattern of each SC user. An a priori market segmentation approach then segments transit passengers into four identifiable types. The methodology proposed in this paper assists transit operators to understand their passengers and provides them oriented information and services.

This paper proposes a new multi-resource multi-stage scheduling problem for optimising the open-pit drilling, blasting and excavating operations under equipment capacity constraints. The flow process is analysed based on the real-life data from an Australian iron ore mine site. The objective of the model is to maximise the throughput and minimise the total idle times of equipment at each stage. The following comprehensive mining attributes and constraints have been considered: types of equipment; operating capacities of equipment; ready times of equipment; speeds of equipment; block-sequence-dependent movement times of equipment; equipment-assignment-dependent operation times of blocks; distances between each pair of blocks; due windows of blocks; material properties of blocks; swell factors of blocks; and slope requirements of blocks. It is formulated by mixed integer programming and solved by ILOG-CPLEX optimiser. The proposed model is validated with extensive computational experiments to improve mine production efficiency at the operational level. The model also provides an intelligent decision support tool to account for the availability and usage of equipment units for drilling, blasting and excavating stages.

Teachers leave the teaching profession at different stages throughout their careers. When mid-career teachers leave the profession, there is a potential loss of experienced, quality staff. Increasingly principals have the responsibility for recruiting and keeping quality staff, which translates to responsibility for arresting the attrition rate. This paper reports on an ongoing study that investigates how school leadership may affect teacher job satisfaction in order to understand how principals can enhance teacher work commitment. This paper uses the domains of leadership identified in Education Queensland’s Leadership Matters Framework (2008) to compare school leaders’ and teachers’ perceptions about mid-career teachers’ leaving the profession. Five current principals and five ex-teachers participated in semi-structured, qualitative, individual interviews about which leadership practices impact on teacher work commitment. The ideas identified by each cohort were coded through a content analysis. The five domains of leadership (i.e., personal, relational, intellectual, organisational and educational leadership) provided an analytical framework. Both participant groups indicated relational leadership practices as the strongest influence on teacher work commitment. The relational skills, such as valuing staff, being approachable, being consistent with staff interactions, having good interpersonal skills and developing staff strengths, were noted to have specific impacts on teachers’ work commitment. There were significant differences between the groups, with the ex-teachers rating the personal leadership practices as the second most important practice that can influence teacher work commitment. In contrast, the principals felt that the organisational and education leadership practices were of next importance for teacher work commitment. The findings have implications for principal leadership professional learning. Improving relational skills may help school leaders to increase teacher work. Teacher attrition is a serious concern to many education jurisdictions and by understanding reasons for decline in commitment, jurisdictions can redress the negative impact of leadership practices and keep teachers committed and in the profession. However, further research needs to incorporate more participants through a quantitative study to validate connections with the qualitative findings presented in this current study.

This research examined formal and informal human resource policies and practices that support work life balance (WLB) in Bhutanese Small and Medium Enterprises (SMEs). Developing countries like Bhutan where small and medium enterprises (SMEs) make up the majority of all enterprises are less likely to encompass formal comprehensive WLB policies that more privileged societies like the US, Canada, Australia, and the UK where the concept of WLB began. Interviews were conducted with 20 employees and 10 employers from 10 SMEs in Bhutan. Results showed that informal practices were the predominant mechanism for employees to manage the multiple roles in their lives. Strong norms of trust between employers and employees supported these informal practices.

Technological change, particularly the growth of the Internet and smart phones, has increased the visibility of male escorts, expanded their client base and diversified the range of venues in which male sex work can take place. Specifically, the Internet has relocated some forms of male sex work away from the street and thereby increased market reach, visibility and access and the scope of sex work advertising. Using the online profiles of 257 male sex workers drawn from six of the largest websites advertising male sexual services in Australia, the role of the Internet in facilitating the normalisation of male sex work is discussed. Specifically we examine how engagement with the sex industry has been reconstituted in term of better informed consumer-seller decisions for both clients and sex workers. Rather than being seen as a ‘deviant’ activity, understood in terms of pathology or criminal activity, male sex work is increasingly presented as an everyday commodity in the market place. In this context, the management of risks associated with sex work has shifted from formalised social control to more informal practices conducted among online communities of clients and sex workers. We discuss the implications for health, legal and welfare responses within an empowerment paradigm.

Australia faces an ongoing challenge recruiting professionals to staff essential human services in rural and remote communities. This paper identifies the private limits to the implicit service contract between professions and such client populations. These become evident in how private solutions to competing priorities within professional families inform their selective mobility and thus create the public problem for such communities. The paper reports on a survey of doctors, nurses, teachers and police with responsibility for school-aged children in Queensland that plumbed the strength of neoliberal values in their educational strategy and their commitment to the public good in career decisions. The quantitative analysis suggested that neoliberal values are not necessarily opposed to a commitment to the public good. However, the qualitative analysis of responses to hypothetical career opportunities in rural and remote communities drew out the multiple intertwined spatial and temporal limits to such public service, highlighting the priority given to educational strategy in these families’ deliberations. This private/public nexus poses a policy problem on multiple institutional fronts.
