Response of segmented bored transit tunnels to surface blast

Increasing threat of terrorism highlights the importance of enhancing the resilience of underground tunnels to all hazards. This paper develops, applies and compares the Arbitrary Lagrangian Eulerian (ALE) and Smooth Particle Hydrodynamics (SPH) techniques to treat the response of buried tunnels to surface explosions. The results and outcomes of the two techniques were compared, along with results from existing test data. The comparison shows that the ALE technique is a better method for describing the tunnel response for above ground explosion with regards to modeling accuracy and computational efficiency. The ALE technique was then applied to treat the blast response of different types of segmented bored tunnels buried in dry sand. Results indicate that the most used modern ring type segmented tunnels were more flexible for in-plane response, however, they suffered permanent drifts between the rings. Hexagonal segmented tunnels responded with negligible drifts in the longitudinal direction, but the magnitudes of in-plane drifts were large and hence hazardous for the tunnel. Interlocking segmented tunnels suffered from permanent drifts in both the longitudinal and transverse directions. Multi-surface radial joints in both the hexagonal and interlocking segments affected the flexibility of the tunnel in the transverse direction. The findings offer significant new information in the behavior of segmented bored tunnels to guide their future implementation in civil engineering applications.

Expulsion of Afghan refugees from Pakistan: A violation of principle of non-refoulement

This article addresses the need of an implementation mechanism for the protection of refugees’ rights. However, it is contended that the principle forms part of Customary International Law, under which it is binding on all states irrespective of whether or not they are parties to the Convention Relating to the Status of Refugees 1951 or its Protocol 1967. Since last decade, U.S and its allies have been fighting to curve terrorism which has raised many issues such as human rights violation, deportation, expulsion, extradition, rendition and many more. Pakistan has played a very critical role in War against Terrorism, particularly in reference of war in Afghanistan. Particular concern of this article is the violation of refugees’ rights in Pakistan in 2008 and 2010. This article would highlight the legislation regarding non-expulsion of Afghan refugees from Pakistan to a territory where they have well founded fear of persecution. Article is divided into three parts, the first one deals with “Principle of Non-Refoulement”, the second one deals with “exceptions to the principle” whereas the last one discusses the violation of the very principle in Pakistan with reference to Afghan refugees.

Dystopian fiction for young people: Instructive tales of resilience

The rise and popularity of dystopian fiction in recent years is quite marked and critics often attribute such high sales of books and box office as being linked to the impact September 11 has had on the world, especially in the United States. While the events of September 11, 2001 saw a heightened anxiety by nations and their citizens about the fear and threat of terrorism – an anxiety which is paradoxically lowered and raised by increased surveillance practices, security checks and warnings – other changes since the last stages of the twentieth century have also raised concerns and anxieties. In this paper I use examples of Young Adult (YA) dystopian fiction to illustrate the potential these texts have for providing their readers with alternative ways of thinking about the challenges that others face and their capacity for resilience.

Minority activism : trends informing political participation across Australian communities

In the late 1990’s, intense and vigorous debate surrounded the impact of minority communities on Australia’s mainstream society. The rise of far-right populism took the stage with the introduction to the political landscape of Pauline Hanson and her One Nation party, whilst John Howard’s Liberal-National Coalition Government took the fore on debate over immigration issues corresponding with an influx of irregular arrivals. In 2001, following the September 11 terrorist attacks in the United States of America and subsequent attacks on western targets globally, many of these issues continued to be debated through the security posturing that followed. In recent years, much effort has been afforded to countering the threat of terrorism from home grown assailants. The Government has introduced stringent legislative responses whilst researchers have studied social movements and trends within Australian communities, particularly with respect to minorities. In 2008, the Scanlon Foundation, in association with Monash University and various government entities, released its findings into its survey approach to mapping social cohesion in Australia. It identified a number of spheres of exploration which it believed were essential to measuring cohesiveness of Australian communities generally including, economic, political and socio-cultural factors (Markus and Dharmalingam, 2008). This doctoral project report will explore the political sphere as identified in the Mapping Social Cohesion project and apply it to identified minority ethnic communities. The Scanlon Foundation project identified political participation as one of a number of true indicators of social cohesion. This project acknowledges that democracy in Australia is represented predominantly by two political entities representing a vast majority of constituents under a compulsory voting regime. This essay will identify the levels of political activism achieved by minority ethnic communities and access to democratic participation within the Australian political structure. It will define a ten year period from 1999 to 2009, identifying trends and issues within minority communities that have proactively and reactively promoted engagement in achieving a political voice, framed within a mainstream-dominated political system. It will research social movements and other influential factors over that period to enrich existing knowledge in relation to political participation rates across Australian communities.

Enhancing professional ethics : service-learning in teacher education

The ethical conduct of professionals has been the focus of increasing scrutiny over the past several decades as members of the public, the media, professional bodies, and legislative authorities have struggled to define ethical behaviour in times of governmental change, increasing internationalisation, globalised communications, threats of terrorism, and the challenges of developments in science and medicine (e.g., Demmke & Bossaert, 2004). National governments and transnational bodies have responded to these concerns about ethics and corruption through measures such as the United Nations Convention Against Corruption (United Nations Office on Drugs and Crime, 2004), Transparency International’s annual corruption index (2010) and Queensland’s Public Sector Ethics Act 1994 (Queensland Parliament 1994). Similarly, academic interest in ethics and its application across a range of domains(e.g., business, health care, social welfare, criminal justice, law, journalism, defence, environment, and media) has also increased. To illustrate, in 1993, a non-partisan, non-profit national umbrella organisation, the Australian Association for Professional and Applied Ethics, was formed following a conference concerned with the teaching of ethics (http://www.arts.unsw.edu.au./aapae/about_aapae/about_aapae.htm), while a recent review of the Excellence in Research for Australian rankings of national and international academic journals revealed that 16 journals related to ethics had received the top ratings of A* or A (Australian Research Council, 2009). In this chapter we examine professional ethics and argue, with specific reference to the context of pre-service teacher education, that Service-learning is one way of enhancing emerging professionals’ understanding of ethics.

Endogenous mortality, human capital and economic growth

We consider growth and welfare effects of lifetime-uncertainty in an economy with human capital-led endogenous growth. We argue that lifetime uncertainty reduces private incentives to invest in both physical and human capital. Using an overlapping generations framework with finite-lived households we analyze the relevance of government expenditure on health and education to counter such growth-reducing forces. We focus on three different models that differ with respect to the mode of financing of education: (i) both private and public spending, (ii) only public spending, and (iii) only private spending. Results show that models (i) and (iii) outperform model (ii) with respect to long-term growth rates of per capita income, welfare levels and other important macroeconomic indicators. Theoretical predictions of model rankings for these macroeconomic indicators are also supported by observed stylized facts.

Contemporary public health policy

- identify the terms policy, public policy and health policy, the stages of policy development and the role that values and politics play in policymaking - recognise contemporary international developments in public health and their impact on national policymaking and the health of Australians - describe the basic structure and financing of Australia’s health system and the role of public health within it - identify Australia’s national public health priorities, and be able to critique the development of the National Chronic Disease Strategy, as an example.

Teaching and Learning in Maritime Security: A Literature Review

With the rise in attacks and attempted attacks on marine‐based critical infrastructure, maritime security is an issue of increasing importance worldwide. However, there are three significant shortfalls in the efforts to overcome potential threats to maritime security: the need for greater understanding of whether current standards of best practice are truly successful in combating and reducing the risks of terrorism and other security issues, the absence of a collective maritime security best practice framework and the need for improved access to maritime security specific graduate and postgraduate (long) courses. This paper presents an overview of existing international, regional national standards of best practice and shows that literature concerning the measurement and/ or success of standards is virtually non‐existent. In addition, despite the importance of maritime workers to ensuring the safety of marine based critical infrastructure, a similar review of available Australian education courses shows a considerable lack of availability of maritime security‐specific courses other than short courses that cover only basic security matters. We argue that the absence of an Australian best practice framework informed by evaluation of current policy responses – particularly in the post 9/11 environment – leaves Australia vulnerable to maritime security threats. As this paper shows, the reality is that despite the security measures put in place post 9/11, there is still considerable work to be done to ensure Australia is equipped to overcome the threats posed to maritime security.

Feminism and Global Justice

This book attempts to persuade a new generation of scholars, criminologists, activists, and policy makers sympathetic to the quest for global justice to open the envelope, to step out of their comfort zones and typical frames of analysis to gaze at a world full of injustice against the female sex, much of it systemic, linked to culture, custom and religion. In some instances the sources of these injustices intersect with those that produce global inequality, imperialism and racism. This book also investigates circumstances where the globalising forces cultivate male on male violence in the anomic spaces of supercapitalism – the border zones of Mexico and the United States, and the frontier mining communities in the Australian desert. However systemic gendered injustices, such as forced marriage of child female brides, sati the cremation of widows, genital cutting, honour crimes, rape and domestic violence against women, are forms of violence only experienced by the female sex. The book does not shirk away from female violence either. Carrington argues that if feminism wants to have a voice in the public, cultural, political and criminological debates about heightened, albeit often exaggerated, social concerns about growing female violence and engagement in terrorism, then new directions in theorising female violence are required. Feminist silences about the violent crimes, atrocities and acts of terrorism committed by the female sex leave anti-feminist explanations uncontested. This allows a discursive space for feminist backlash ideologues to flourish. This book contests those ideologies to offer counter explanations for the rise in female violence and female terrorism, in a global context where systemic gendered violence against women is alarming and entrenched. The world needs feminism to take hold across the globe, now more than ever.

Practice briefing : Is BOT the best financing model to procure infrastructure projects? A case study of the Hong Kong-Shuhai-Macau Bridge

Abstract: Purpose – Several major infrastructure projects in the Hong Kong Special Administrative Region (HKSAR) have been delivered by the build-operate-transfer (BOT) model since the 1960s. Although the benefits of using BOT have been reported abundantly in the contemporary literature, some BOT projects were less successful than the others. This paper aims to find out why this is so and to explore whether BOT is the best financing model to procure major infrastructure projects. Design/methodology/approach – The benefits of BOT will first be reviewed. Some completed BOT projects in Hong Kong will be examined to ascertain how far the perceived benefits of BOT have been materialized in these projects. A highly profiled project, the Hong Kong-Zhuhai-Macau Bridge, which has long been promoted by the governments of the People's Republic of China, Macau Special Administrative Region and the HKSAR that BOT is the preferred financing model, but suddenly reverted back to the traditional financing model to be funded primarily by the three governments with public money instead, will be studied to explore the true value of the BOT financial model. Findings – Six main reasons for this radical change are derived from the analysis: shorter take-off time for the project; difference in legal systems causing difficulties in drafting BOT agreements; more government control on tolls; private sector uninterested due to unattractive economic package; avoid allegation of collusion between business and the governments; and a comfortable financial reserve possessed by the host governments. Originality/value – The findings from this paper are believed to provide a better understanding to the real benefits of BOT and the governments' main decision criteria in delivering major infrastructure projects.

Romantic terrorism: An autoethnography of domestic violence, victimization and survival

Romantic Terrorism offers an innovative methodology in exploring the ways in which domestic violence offenders terrorise their victims. Hayes and Jeffries employ a collaborative auto-ethnographic approach to analyse their own lived experiences of domestic violence, particularly how romantic love is employed and distorted by abusers. Its focus on the insidious use of tactics of coercive control by abusers opens up much-needed discussion on the damage caused by emotional and psychological abuse, which are often overlooked or downplayed in both the literature and the criminal justice system. To this end, it offers strategic advice for policy-makers, practitioners, and criminal justice professionals involved in domestic violence service provision.
