Just over a decade ago the authors set out to select and follow a range of young people from the age of 12 and their end of primary or first days in secondary school, to the age of 18 when most of them had embarked on the first steps of the post-school lives. Students from four different types of schools were chosen: a Melbourne high school, a high school in a Victorian regional city, a large non-government school, and a secondary school that had once been a technical school. The students were interviewed twice a year about their views of self, of school, of the future. In this article the authors discuss two aspects of the study: what sense did they get of schools and their effects on the subjectivities being formed by young people today? And, what sense did the authors get of how gender is working in young lives now? The article outlines some of the findings in relation to these two issues.

Futures education (FE) in a rapidly changing world is critical if young people are to be empowered to be proactive rather than reactive about the future. Research into young people's images and ideas of the future lead to the disturbing conclusion that, for many, the future is a depressing and fearful place where they feel hopeless and disempowered. On the other hand, as Richard Slaughter writes, 'young people are passionately interested in their own futures, and that of the society in which they live. They universally 'jump at the chance to study something with such intrinsic interest that also intersects with their own life interests in so many ways'. FE explicitly attempts to build on this interest and counter these fears by offering a profound and empowering set of learning strategies and ideas that can help people think and act critically and creatively about the future, without necessarily trying to predict it. Futures educators have, over the past decades, developed useful tools, ideas and a language for use with students of all ages to enable them to develop foresight literacy. Most of us tend to view the future as somehow beyond the present and rarely consider how decisions and choices made today profoundly affect not just one fixed future but any number of futures. The underlying goal of FE is to move from the idea of a single, pre-determined future to that of many possible futures, so that students begin to see that they can determine the future, that they need not be reactive and that they are not powerless. How does one do that? Ideas include, but are not limited to: timelines and Y-diagrams, futures wheels and mind maps, and 'Preferable, possible and probable' futures - a.k.a. the 3Ps. Current Australian curricula present education about the future in various implicit or explicit guises. A plethora of statements and curriculum outcomes mention the future, but essentially take 'it' for granted, and are uninformed by FE literature, language, ideas or tools. Science, the humanities and technology tend to be the main areas where such an implicit futures focus can be found. It also appears in documents about vocational education, civics and lifelong learning. Explicit FE is, as Beare and Slaughter put it, still the missing dimension in education. Explicit FE attempts to develop futures literacy, and draws widely upon futures studies literature for processes and content. FE provides such a wide range of ideas and tools that it can be incorporated into education in any number of ways. Programs in two very different schools, one primary and one secondary, are described in this article to provide examples of some of these ways. The first school, Kimberley Park State Primary School in Brisbane, operates with multi-age classrooms based on a 'thinking curriculum' developed around four organisers: change, perspectives, interconnectedness and sustainability. The second school, St John's Grammar School in Adelaide, is an independent school where FE operates as an integrated approach in Year Seven, as a separate one-semester subject in Year Nine and in separate subjects at other levels. Teachers both at Kimberley Park and St John's are very positive about FE. They say it promotes valuable and authentic learning, assists students to realise they have choices that matter and helps them see that the future need not be all doom and gloom. Because students are interested in the Big Questions, as one teacher put it, FE provides a perfect opportunity to address them, and to consider values that are fundamental for them and the future of the planet. Like any innovation, the long-term success of FE in schools depends on an embedding process so that the innovation does not depend on the enthusiasm and energy of a few individuals, only to disappear when they move on. It requires strong leadership, teacher knowledge, support and enthusiasm, and the support and understanding of the wider school community.

The concept of dispositional resistance to change has been introduced in a series of exploratory and confirmatory analyses through which the validity of the Resistance to Change (RTC) Scale has been established (S. Oreg, 2003). However, the vast majority of participants with whom the scale was validated were from the United States. The purpose of the present work was to examine the meaningfulness of the construct and the validity of the scale across nations. Measurement equivalence analyses of data from 17 countries, representing 13 languages and 4 continents, confirmed the cross-national validity of the scale. Equivalent patterns of relationships between personal values and RTC across samples extend the nomological net of the construct and provide further evidence that dispositional resistance to change holds equivalent meanings across nations.

Multisensor data fusion has attracted a lot of research in recent years. It has been widely used in many applications especially military applications for target tracking and identification. In this paper, we will handle the multisensor data fusion problem for systems suffering from the possibility of missing measurements. We present the optimal recursive fusion filter for measurements obtained from two sensors subject to random intermittent measurements. The noise covariance in the observation process is allowed to be singular which requires the use of generalized inverse. Illustration example shows the effectiveness of the proposed filter in the measurements loss case compared to the available optimal linear fusion methods.

"This book offers a critical reassessment of the "Asian values" debate, which dominated the human rights discourse in the late 1990s, and a reappraisal of the human rights situation in Asia since then. In this book Asian and non-Asian scholars contextualize the "Asian values" debate and examine in what ways the issues raised then continue to trouble Asian societies. Human rights are seen both in the context of political developments in individual Asian countries as well as in relation to global issues such as the Global War on Terror. The book challenges the reader to critically examine human rights rhetoric and practice both in Asia and globally."--BOOK JACKET.

Although the practice of forensic and correctional psychology has been understood in relation to certain sets of values that have been articulated in codes of ethical practice or organisational mission statements, there has been little consideration of how the values of offenders can inform the rehabilitative process. In this paper the criminogenic nature of values is discussed and how these might be addressed in an intervention. It is concluded that an exploration of values is not only a necessary condition for successful rehabilitation, but also essential if ethical problems in working with offenders are to be avoided.
