Identity-based signcryption

The notion of identity-based IB cryptography was proposed by Shamir [177] as a specialization of public key PK cryptography which dispensed with the need for cumbersome directories, certificates, and revocation lists.

Fostering rapid transitions to education for sustainable development through a whole-system approach to curriculum and organizational change

Despite decades of attempts to embed sustainability within higher education, literature clearly suggests that highly regulated disciplines such as engineering have been relatively slow to incorporate sustainability knowledge and skill areas, and are generally poorly prepared to do so. With current efforts, it is plausible that sustainability could take another two decades to be embedded within the curriculum. Within this context, this paper presents a whole system approach to implement systematic, intentional and timely curriculum renewal that is responsive to emerging challenges and opportunities, encompassing curriculum and organizational change. The paper begins by considering the evolution of curriculum renewal processes, documenting a number of whole system considerations that have been empirically distilled from literature, case studies, pilot trials, and a series of workshops with built environment educators from around the world over the last decade. The paper outlines a whole-of-institution curriculum renewal approach to embedding sustainability knowledge and skills within the DNA of the institutional offerings. The paper concludes with a discussion of research and practice implications for the field of education research, within and beyond higher education.

Influence of cytochrome P-450 inhibitors on the inhalative uptake of methyl chloride and methylene chloride in male B6C3F1 mice

Dichloromethane (DCM) is thought to be metabolized in vivo by two independent pathways: a glutathione (GSH) dependent pathway that yields CO2 and a cytochrome P-450 mediated one that yields both CO and CO2 (Gargas et al 1986). With a physiologically based pharmacokinetic (PB-PK) model, Andersen et al (1987) calculate the quantitative parameters for both metabolic pathways. Using the kinetic parameters thus obtained and the results of two carcinogenicity studies with rodents (Serota et al 1986; NTP 1985), the authors then estimate the tumour risk for humans.

Troubling silences and taboo texts : constructing safer and more positive school climates for same-sex attracted high school students in Australia

This chapter offers three insights into the relationship between curriculum decision making, positive school climate, and academic achievement for same-sex attracted (SSA) students, highlighting the need for students to be offered more than heteronormative narratives and silence on issues of sexuality in the official school curriculum. The authors firstly provide a review of research and report on findings of a doctoral study (Mikulsky, 2007) explaining the impact of SSA students’ perceptions of school climate on their motivation and academic self-concept. Situating the work in the context of the Australian Curriculum for English and associated classroom texts, the dominant discourse of ‘straight, white female’ heroines as exemplified in the globally popular young adult novel The hunger games and other texts popular with Australian students are critiqued, with an argument made for expanding notions of what it means to ‘attend to’ gender and sexuality through textual choice and critical pedagogy. The authors show how texts that feature LGBTQ characters and storylines continue to be marginalized and constructed as taboo and demonstrate how curricular choices can and do impact academic outcomes for marginalized students. Issues of gender and sexuality are framed as a cross-curriculum imperative, with recommendations made for the explicit inclusion of materials exploring gender and sexuality in the official curriculum of all key learning areas.

Inclusion?

Whilst inclusive education is a relatively recent advance in our thinking about schooling and pedagogy, it is rapidly establishing movement simultaneously reflected in and refracted by education policy, research, and scholarship. This is manifest in the proliferation of policy texts and programmes generated by education jurisdictions globally and locally, and in the burgeoning number of scholarly texts, academic conferences, and research grants dedicated to inclusive education.

Beyond the Producer/Consumer Divide : Key Principles of Produsage and Opportunities for Innovation

Though popular, concepts such as Toffler's 'prosumer' (1970; 1980; 1990) are inherently limited in their ability to accurately describe the makeup and dynamics of current co-creative environments, from fundamentally non-profit initiatives like the Wikipedia to user-industry partnerships that engage in crowdsourcing and the development of collective intelligence. Instead, the success or failure of such projects can be understood best if the traditional producer/consumer divide is dissolved, allowing for the emergence of the produser (Bruns, 2008). A close investigation of leading spaces for produsage makes it possible to extract the key principles which underpin and guide such content co-creation, and to identify how innovative pro-am partnerships between commercial entities and user communities might be structured in order to maximise the benefits that both sides will be able to draw from such collaboration. This chapter will outline these principles, and point to successes and failures in applying them to pro- am initiatives.

Historical intake and elimination of polychlorinated biphenyls and organochlorine pesticides by the Australian population reconstructed from biomonitoring data

Quantifying the competing rates of intake and elimination of persistent organic pollutants (POPs) in the human body is necessary to understand the levels and trends of POPs at a population level. In this paper we reconstruct the historical intake and elimination of ten polychlorinated biphenyls (PCBs) and five organochlorine pesticides (OCPs) from Australian biomonitoring data by fitting a population-level pharmacokinetic (PK) model. Our analysis exploits two sets of cross-sectional biomonitoring data for PCBs and OCPs in pooled blood serum samples from the Australian population that were collected in 2003 and 2009. The modeled adult reference intakes in 1975 for PCB congeners ranged from 0.89 to 24.5 ng/kg bw/day, lower than the daily intakes of OCPs ranging from 73 to 970 ng/kg bw/day. Modeled intake rates are declining with half-times from 1.1 to 1.3 years for PCB congeners and 0.83 to 0.97 years for OCPs. The shortest modeled intrinsic human elimination half-life among the compounds studied here is 6.4 years for hexachlorobenzene, and the longest is 30 years for PCB-74. Our results indicate that it is feasible to reconstruct intakes and to estimate intrinsic human elimination half-lives using the population-level PK model and biomonitoring data only. Our modeled intrinsic human elimination half-lives are in good agreement with values from a similar study carried out for the population of the United Kingdom, and are generally longer than reported values from other industrialized countries in the Northern Hemisphere.

In Perpetual Motion: Theories of Power, Educational History, and the Child

"In Perpetual Motion is an "historical choreography" of power, pedagogy, and the child from the 1600s to the early 1900s. It breaks new ground by historicizing the analytics of power and motion that have interpenetrated renditions of the young. Through a detailed examination of the works of John Locke, Jean-Jacques Rousseau, Johann Herbart, and G. Stanley Hall, this book maps the discursive shifts through which the child was given a unique nature, inscribed in relation to reason, imbued with an effectible interiority, and subjected to theories of power and motion. The book illustrates how developmentalist visions took hold in U.S. public school debates. It documents how particular theories of power became submerged and taken for granted as essences inside the human subject. In Perpetual Motion studiously challenges views of power as in or of the gaze, tracing how different analytics of power have been used to theorize what gazing could notice."--BOOK JACKET.

Dangerous Coagulations? The Uses of Foucault in the Study of Education

This book brings together an outstanding group of scholars who draw on the works of Michel Foucault. Eclectic in topic and method, the essays illustrate Foucault’s usefulness. Dangerous Coagulations? constitutes a departure from the more formulaic Foucault work that has emerged and highlights new possibilities for undertaking problematizing approaches to educational research.

Wife beating: A measure to deal with marital disharmony or a license for misconduct

Wife beating is not a new phenomena rather it has been practiced from pre historic time till date. This was due to the fact that in all the civilizations and under all religions, woman was considered subjugated to men. Her natural physical weakness had also made her vulnerable for violence. Islam reinforced womanhood by protecting her rights and providing her respect in the family and society at large. However, it is not interpreted accurately in male dominant society due to the existence of a patriarchal social setup. Adding to the ignorance regarding the position of women in Islam, the presence of injustice and mal practices in contemporary Muslim societies has been taken up as a weak point of Islam by non Muslims as well by less informed Muslims. The reasons for denying women’s rights in Pakistani society could be summed up as lack of education, ignorance about Islamic teachings, feudal and tribal cultural traditions, male dominated patriarchal attitudes, poverty, unemployment and misinterpretations regarding precise teachings of Quran and Sunnah. There are many misconceptions regarding the stance of Islam on wife beating as well. It is commonly understood that Islam gives permission for wife beating in the Quranic verse 4:34. This article will describe the relationship between husband and wife in the light of Quranic verse4:34 and will explore the sanctions of wife beating and its dimensions. Furthermore, it will aim to remove misunderstandings and prejudged opinions related to the concerned issue, in the light of Quran and Sunnah.

Evolution of the concept of compulsory licensing: A critical analysis of key developments before and after TRIPS

Patents provide monopoly rights to patent holders. There are safeguards in patent regime to ensure that exclusive right of the patent holder is not misused. Compulsory licensing is one of the safeguards provided under TRIPS using which patent granting state may allow a third party to exploit the invention without patent holder’s consent upon terms and conditions decided by the government. This concept existed since 1623 and was not introduced by TRIPS for the first time. But this mechanism has undergone significant changes especially in post-TRIPS era. History of evolution of compulsory licensing is one of the least explored areas of intellectual property law. This paper undertakes an analysis of different phases in the evolution of the compulsory licensing mechanism and sheds light on reasons behind developments especially after TRIPS.

Hashtag as hybrid forum: The case of #agchatoz

This chapter imports Michel Callon’s model of the ‘hybrid forum’ (Callon et al, 2009, p. 18) into social media research, arguing that certain kinds of hashtag publics can be mapped onto this model. It explores this idea of the hashtag as hybrid forum through the worked example of #agchatoz—a hashtag used as both ‘meetup’ organizer for Australian farmers and other stakeholders in Australian agriculture, and as a topic marker for general discussion of related issues. Applying the principles and techniques of digital methods (Rogers, 2013), we employ a standard suite of analytics to a longitudinal dataset of #agchatoz tweets. The results are used not only to describe various elements and dynamics of this hashtag, but also to experiment with the articulation of such approaches with the theoretical model of the hybrid forum, as well as exploring the ways that controversies animate and transform such forums as part of the emergence and cross-pollination of issue publics.
