A critical look at cryptographic hash function literature

The cryptographic hash function literature has numerous hash function definitions and hash function requirements, and many of them disagree. This survey talks about the various definitions, and takes steps towards cleaning up the literature by explaining how the field has evolved and accurately depicting the research aims people have today.

‘Doing’ social justice in early childhood : the potential of leadership

Early childhood education has long been connected with objectives related to social justice. Australian Early Childhood Education and Care (ECEC) has its roots in philanthropic and educational reform movements prevalent at the turn of the 20th century. More recently, with the introduction of the National Early Childhood Reform Agenda, early childhood education has once more been linked to the achievement of aims associated with redressing inequality and disadvantage. According to Jean-Marie, Normore and Brooks (2009), educational leaders have a moral and social obligation to foster equitable practices through advocating for traditionally marginalised and poorly served students while creating a new social order “...that subverts the long standing system that has privileged certain students while oppressing or neglecting others” (p.4). Drawing on extant literature, including data from two previously reported Australian studies in which leadership emerged as having a transformational impact on service delivery, this paper examines the potential of early childhood leadership to generate ‘socially just’ educational communities. With reference to critical theory, we argue that critically informed, intentional and strategic organisational leadership can play a pivotal role in creating changed circumstances and opportunities for children and families. Such leadership includes positional and distributed elements, articulation of values and beliefs, and collective action that is mindful and informed.

A new life of Hans Christian Andersen : a study of the ‘peculiar nature’ of an author’s life

A review of "Hans Christian Andersen : European Witness" by Paul Binding (Yale UP, 2014). How a writer bears witness to his age is necessarily the expression of many things, not least the possibly quite peculiar nature of an author’s life. Literary works often emerge from complex upbringings, from periods of youthful isolation spent reading and writing. More still seem to have been written as a result of the fraught relationships that befall authors, perhaps because authors so often view their relationships with a degree of creative and critical distance. And yet, if a writer’s output evidences an unusual life, it also witnesses broader questions being asked by a community as a whole. At some level, even the most remarkable figures are typical of their age, and reflections of it. By the close of Paul Binding’s study of the life and works of Hans Christian Andersen (1805–75), we are reminded that extraordinary feats of originality and imagination are often the result of how unique minds enter wider discourses...

Critical linguistics in the early years : exploring functions of language through sophisticated picture books and process drama strategies

In this chapter we describe a critical fairytales unit taught to 4.5 to 5.5 year olds in a context of intensifying pressure to raise literacy achievement. The unit was infused with lessons on reinterpreted fairytales followed by process drama activities built around a sophisticated picture book, Beware of the Bears (MacDonald, 2004). The latter entailed a text analytic approach to critical literacy derived from systemic functional linguistics (Halliday, 1978; Halliday & Matthiessen, 2004). This approach provides a way of analysing how words and discourse are used to represent the world in a particular way and shape reader relations with the author in a particular field (Janks, 2010).

Early onset dementia: A narrative review of the literature

Over the past forty years, significant research has been conducted on the epidemiology of late onset dementia. Less is known however, about the prevalence, incidence and burden of illness of early onset dementia (occurring prior to 65 years of age). The purpose of this narrative review is to examine existing literature regarding the experiences and implications of living with early onset dementia for patients, caregivers, and family members. The following questions were addressed: (1) What is the impact of early onset dementia on patients, families and carers? and; (2) What are the needs of patients with early onset dementia and their family and carers? Key findings form this review are presented.

A critical evaluation of literature on robot path planning in dynamic environment

Robot Path Planning (RPP) in dynamic environments is a search problem based on the examination of collision-free paths in the presence of dynamic and static obstacles. Many techniques have been developed to solve this problem. Trapping in a local minima and maintaining a Real-Time performance are known as the two most important challenges that these techniques face to solve such problem. This study presents a comprehensive survey of the various techniques that have been proposed in this domain. As part of this survey, we include a classification of the approaches and identify their methods.

Editorial of "International Journal of Critical Indigenous Studies, Volume 6, Number 1, 2013"

This edition of the International Journal of Critical Indigenous Studies marks the tenth since the journal’s launch in 2008. During that time, over forty articles and eleven book reviews have been published, which is testament to the continuing upward trajectory of Critical Indigenous Studies. Although there continues to be an increasing range of areas of Indigenous research to which a critical focus is brought to bear, a consistent issue for many of the journal’s contributors has been the delineation and application of Indigenous methods and methodologies in social research. The present edition is no exception, with two articles focussing on Indigenous-centred research. The first, by Krystal Summers, reflexively explores the author’s experiences as an undergraduate student undertaking Indigenous-centred research in Peru. As an Indigenous First Nations woman, Summers was mindful that her research practice was faithful to the ethics and protocols outlined in her original project proposal. Her subsequent ‘journey of critical reflexive understanding and storytelling’ supports the proposition of current literature in Indigenous research methodologies that a properly critical Indigenous ethnography will naturally enjoin with Indigenous epistemologies and methodologies.

Editorial of "International Journal of Critical Indigenous Studies, Volume 7, Number 1, 2014"

This edition testifies to the broad international reach of the journal, with contributions variously concerned with Arctic Indigenous communities, the Métis of Canada, Native Hawaiians and Māori of Aotearoa (New Zealand). Two articles stress the need to work collaboratively and respectfully with Indigenous populations whilst conducting research. The first, by Gwen Healey, notes the increased interest in health research in the Arctic, particularly with Inuit populations. Healy seeks to add to the growing body of literature concerned with Indigenous ways of knowing by highlighting Inuit concepts that inform an effective Arctic research model. The second, by primary author Peter Hutchinson and a range of co-contributors, highlights the ways in which Métis collaborators working in health developed a participatory Indigenous research method that was unique in that it foregrounded Métis relationships and relationality. In so doing, the researchers were able to give substance to otherwise staid policy statements about the need for good ethical research conduct.

Editorial of "International Journal of Critical Indigenous Studies, Volume 8, Number 2, 2015"

The articles in this edition address two critical concerns that can be broadly characterised as Indigeneity as a spectacle and the elision of Indigenous sovereignty by multiculturalism and diversity. The first article, by Maryrose Casey, examines nineteenth and early twentieth century Indigenous performances that drew on cultural practices for entertainment. She highlights how these commercially driven performances were, in fact, demonstrations of sovereignty that white colonisers paid to observe. A measure of the success of these demonstrations can be found in the reactions of audiences, which often involved disrupting the spectacle by physically occupying the performance space.

Opportunity Exploration and Exploitation in International New Ventures: A Study of Relationships’ Involvement in Early Entrepreneurial and Internationalisation Events

International new ventures (INVs) are firms that engage very early after their foundation, if not immediately, in inter-national activities. INVs are a relatively recent phenomenon that deviates from earlier theories on international business. In order to develop our understanding of the emergence and early internationalisation of INVs three different research areas are built upon in the dissertation: International Entrepreneurship, Entrepreneurship and Networks. Net-works have been identified as important for INVs. However, there is a lack of more profound studies regarding the way different types of relationships influence INVs. Few studies are concerned with exploration and exploitation of opportunities and research on the benefits and drawbacks of entrepreneurs’ relationships for the international opportunity recognition process has been called for. By taking a network approach to opportunity exploration and exploitation, the dissertation develops our under-standing of how entrepreneurs’ relationships are involved in exploring and exploiting opportunities during an INV’s early and critical entrepreneurial and internationalisation events. The critical events are studied during three phases: pre-founding, start-up and early internationalisation. Since internationalisation is present from the very beginning, the early internationalisation phase may be parallel to both the pre-founding and the start-up phase. The dissertation contributes to international entrepreneur-ship research in mainly two ways. First, by offering a deep insight into which opportunity exploration and exploitation activities entrepreneurs’ relationships are involved. Second, by adding to our understanding of what the relationships contribute to these activities, mainly in the sense of benefits gained through the relationships. Studying micro firms in real time in their early development towards INVs is considered a unique contribution of the study as it offers valuable insights into pre-founding, start-up, pre-internationalisation as well as early internationalisation. The study shows that in order to understand the development of INVs, it is beneficial to go back to times when there was no thought of starting the INV. By focusing on the entrepreneurs’ background and relationships a more complete picture of the INV is gained. Relationships created at former workplaces or during school time might be the ones that develop business opportunities and set off internationalisation. By focusing on the pre-founding phase, the study also contributes to entrepreneurship literature as this stage has often been neglected or assumed obvious in earlier research. This dissertation shows that an important and mostly lengthy pre-founding phase precedes the decision to start a f rm. In addition, the integration of entrepreneurs’ real experiences with existing theory to develop a continuum for the strength of relationships allows for contributions to network theory.

Do we know the strength of the chorioamnion? A critical review and analysis

The chorioamnion is the membrane that surrounds the fetus during gestation. Normally, it must remain intact for the duration of pregnancy, 37-42 weeks, and only rupture during or just before labour and delivery of the fetus. In a significant number (3%) of all births, this does not happen, and membranes rupture before term, resulting in preterm birth and significant perinatal morbidity. It is known that the material properties of chorioamnion may play a major role in mechanical rupture; a number of studies have been undertaken to characterise the physical nature of chorioamnion and examine factors that may predispose to rupture. However, the existing literature is inconsistent in its choice of both physical testing methods and data analysis techniques, motivating the current review. Experimental data from a large number of chorioamnion mechanical studies were collated, and data were converted to standard engineering quantities. The failure strength of the chorioamnion membrane was found consistently to value approximately 0.9 MPa. It is hoped that past and future studies of membrane mechanics can provide insight into the role of chorioamnion in labour and delivery. In addition, biomechanical approaches can help elucidate the potential causes of early rupture, and suggest future protocols or treatments that could both diagnose and prevent its occurrence. © 2009 Elsevier Ireland Ltd.
