This theoretically innovative anthology investigates the problematic linkages between conserving cultural heritage, maintaining cultural diversity, defining and establishing cultural citizenship, and enforcing human rights.

It is the first publication to address the notions of cultural diversity, cultural heritage and human rights in one volume. Heritage provides the basis of humanity’s rich cultural diversity. While there is a considerable literature dealing separately with cultural diversity, cultural heritage and human rights, this book is distinctive and has contemporary relevance in focusing on the intersection between the three concepts. Cultural Diversity, Heritage and Human Rights establishes a fresh approach that will interest students and practitioners alike and on which future work in the heritage field might proceed.

We report an Mg-based metallic glass/titanium interpenetrating phase composite in which constituent phases form a homogeneously interconnected network. The porous titanium constrains shear bands propagation thoroughly and promotes shear bands branching and intersection subsequently. The homogeneous phase distribution promotes regularly distributed local shear deformation and leads to a uniform deformation for the composites. Moreover, the interpenetrating phase structure introduces a mutual-reinforcement between metallic glass and titanium. Therefore, the composite exhibits excellent mechanical performance with compressive fracture strength of 1783 MPa and fracture strain of 31%.

This study examined how objective measures of the local road environment related to safety were associated with change in physical activity (including active transport) among youth. Few longitudinal studies have examined the impact of the road environment on physical activity among children/adolescents in their neighborhoods. Participants were children aged 8–9 years (n=170) and adolescents aged 13–15 years (n=276) in 2004. Data were collected in 2004 and 2006 during followup of participants recruited initially in 2001 from 19 primary schools in Melbourne, Australia. Walking/cycling to local destinations was parent-reported for children and self-reported by adolescents. Moderate-to-vigorous physical activity (MVPA) during nonschool hours was recorded using accelerometers. Road environment features in each participant’s neighborhood (area within 800 m radius of their home) were measured objectively using a Geographical Information System. Linear regression analyses examined associations between road features and changes in active transport (AT) and MVPA over 2 years. Children’s AT increased but MVPA levels decreased in both age groups; on average, younger girls recorded the greatest declines. The number of traffic/pedestrian lights was associated with ΔAT among younger girls (B=0.45, p=0.004). The total length of walking tracks (in meters) was associated with ΔAT among younger girls (B=0.0016, p=0.015) and adolescent girls (B=0.0016, p=0.002). For adolescent boys, intersection density was associated with ΔAT (B=0.03, p=0.030). Slow points were associated with ΔMVPA among younger boys before school (B=1.55, p=0.021), while speed humps were associated with ΔMVPA among adolescent boys after school (B=0.23, p=0.015). There were many associations for adolescent girls: for example, the total length of local roads (B=0.49, p=0.005), intersection density (B=0.05, p=0.036), and number of speed humps (B=0.33, p=0.020) were associated with ΔMVPA during nonschool hours. Safety-related aspects of the built environment are conducive to physical activity among youth and may help stem age-related declines in physical activity. Passive road safety interventions may promote AT and physical activity among less active girls, in particular.

The ability for a bio-operator to utilise a haptic device to manipulate a microrobot for intracellular injection offers immense benefits. One significant benefit is for the bio-operator to receive haptic guidance while performing the injection process. In order to address this, this paper investigates the use of haptic virtual fixtures for cell injection and proposes a novel force field virtual fixture. The guidance force felt by the bio-operator is determined by force field analysis within the virtual fixture. The proposed force field virtual fixture assists the bio-operator when performing intracellular injection by limiting the micropipette tip's motion to a conical volume as well as recommending the desired path for optimal injection. A virtual fixture plane is also introduced to prevent the bio-operator from moving the micropipette tip beyond the deposition target inside the cell. Simulation results demonstrate the operation of the guidance system.

This article analyzes preconceptions about fidelity critisism in screen adaptation. It argues that the paragone, the ancient comparison and rivalry between the visual and verbal arts over-determined fidelity criticism. Also noted is the concept of intersection, an adaptation type distinguishable from a faithful transposition, introduction by professor Dudley Andrew. The translation and film adaptation of theatre is said to be adressed by professor Phyllis Zatlin. One source of differences arising from inter-medial translation is textual transfer.

Kathryn Bigelow has undoubtedly been one of Hollywood's most significant female players, well known in popular terms for films such as Point Breakand Blue Steel, yet relatively unexplored in academia. Soundbites about women and guns and speculation about the role of ex-husband James Cameron ( Aliens, Titanic) in her career have often helped obscure rather than elucidate an understanding of her work. This collection explores how Bigelow can be seen to provide a point of intersection to a whole range of issues at the forefront of contemporary film studies and of the transformation of Hollywood into a post-classical cinema machine, with a particular emphasis on her most ambitious and controversial picture, Strange Days. Her place within new Hollywood is as a filmmaker that blurs genre conventions, reinscribes gender identites, and produces a breathless cinema of attractions.

This paper reports on the use of the Index for Inclusion in five socioeconomically different primary school contexts in Indonesia. The research was designed and developed through Australian and Indonesian teachers and teacher educators collaborative efforts over a year. The work took place during the post‐Suharto reform period and focuses on the field of Civics education. The research examines what the ethic of inclusion means to teachers participating in political and educational democratization as they attempt to embrace and develop citizenship classroom practices that feature respect for difference. The theoretical interest is in both citizenship theory and inclusion; showing how the civic cultures of school and nation intersect; and the implications of that intersection for inclusion theory and cross‐cultural theorizing of inclusion more broadly.

Suppes-Sen dominance or SS-proofness (SSP) is a commonly accepted criterion of impartiality in distributive justice. Mariotti (Review of Economic Studies, 66, 733–741, 1999) characterized the Nash bargaining solution using Nash’s (Econometrica, 18, 155–162, 1950) scale invariance (SI) axiom and SSP. In this article, we introduce equity dominance (E-dominance). Using the intersection of SS-dominance and E-dominance requirements, we obtain a weaker version of SSP (WSSP). In addition, we consider α − SSP, where α measures the degree of minimum acceptable inequity aversion; α − SSP is weaker than weak Pareto optimality (WPO) when α = 1. We then show that it is still possible to characterize the Nash solution using WSSP and SI only or using α -SSP, SI, and individual rationality (IR) only for any a Î [0,1)[01). Using the union of SS-dominance and E-dominance requirements, we obtain a stronger version of SSP (SSSP). It turns out that there is no bargaining solution that satisfies SSSP and SI, but the Egalitarian solution turns out to be the unique solution satisfying SSSP.

This paper is concerned with expanding knowledge of how femininity/sexuality intersections are constituted in secondary schools. Existing studies have drawn upon Judith Butler’s notion of a ‘heterosexual matrix’ in order to understand how intersections of femininity/sexuality are produced in schools through normative discourses of heterosexuality and gender. Drawing on ‘after-queer’ theoretical resources from within cultural studies that focus on the deployment of notions of sexuality within constructions of intelligible citizenship, I explore how the femininity/sexuality intersection within secondary schools might be complicated, when the significance of discourses of ‘girl power’, linked with successful neoliberal citizenship, is considered. I analyse young women’s discussions of key ‘girl power’ icons in popular culture, generated through fieldwork in an elite girls’ school in Australia. Throughout the analysis I explore how understanding intersections of femininity/sexuality in secondary schools requires an analytical framework that can attend to both familiar notions of heterosexuality and gender – and their ongoing currency – as well as how notions of sexuality are mobilized in the production of successful neoliberal girl citizens. I propose that this analytical approach is useful in terms of avoiding the reinscription of sexuality identity categories in education research.

The tedious task of manually placing feathers on computer animated objects involves aligning feathers, ensuring that they do not insect each other or penetrate the surface, deforming every feather to match the local surface features, and ensuring that the feather coat is consistent when the underlying object is animated.

We present a technique for generating a feather coat over an object. Feather orientation is specified quickly and easily, feathers are deformed while ensuring collision prevention, and the coat can be animated. We create a vector field in the space surrounding the body object and deform feathers to align with the field lines. The non-intersection property of the field lines ensures that feather intersections are avoided. We provide a formulation of a suitable vector field and demonstrate that it is capable of producing realistic feather coats. The process can easily be integrated into the work-flow of standard modelling and animation processes.

We show examples of feather coat creation on a range of objects, proving that field line based placement of feather coats provides the desired functionality for feather modelling and animation.

Numerical study of the natural-convection flow and heat transfer in a dome-shaped, heat-generating, porous enclosure is considered. The general conic equation for the top dome is used to consider various conical top sections such as circular, elliptical, parabolic, and hyperbolic. The individual effect of fluid Rayleigh, Darcy, and heat-generating parameters on flow patterns and heat transfer rates are analyzed and presented. The predicted results show that the heat-generating parameter has the most significant contribution toward the growth of bicellular core flow. Moreover, there is significant change in temperature distribution in comparison to rectangular enclosures, due to the existence of the domed-shape top adiabatic cover. The results also show that, regardless of Darcy and Rayleigh values, a flat adiabatic top cover tends to yield the highest value of Nusselt number, followed by circular, elliptical, parabolic, and hyperbolic top covers, respectively.

Youth and risk are artefacts of expertise, constructed at the intersection of a wide range of knowledges about Youth and so-called Youth issues: an intersection marked by institutionalised, scientific representations of education, family, the life course, risk, and so on. In this paper I suggest that the messiness of human experiences and existence requires knowledge practices in the social sciences that can rethink what counts as truth. These interests – which are grounded in the knowledge practices that frame the work being undertaken in a large scale, qualitative investigation of the cultural drivers shaping the alcohol practices of 14 to 24 year old Australian’s - will be addressed through a discussion of the ways in which Tim Winton’s (2008) new novel Breath can be read as an allegorical tale about the terror of being ordinary: and of the teenage years as being a time in a life in which the fear of being ordinary compels Winton’s key characters to seek out, sometimes stumble upon, and embrace that which promises to make their’s a life less ordinary. In these recollections risk is something that breathes energy and purpose into lifeworlds that are dominated by the institutionalised ordinariness of family, school, and work.
