An ethical approach to sharing school successes in times of high-stakes accountability

High-stakes testing has become an important element of the Australian educational landscape. As one part of the neo-liberal paradigm where beliefs in the individual and the free market are paramount, it is of concern how school leaders can respond to this phenomenon in an ethical manner. Ethics and ethical leadership have increased in prominence both in the educational administration literature and in the media (Cranston, Ehrich, & Kimber, 2006). In this paper we consider ethical theories on which school principals can draw, not only in the leadership of their own schools but in their relationships with other schools. We provide an example of a school leader sharing a successful intervention with other schools, illustrating that school leaders can create spaces for promoting the public good within the context of high-stakes testing.

Programming: Reading, writing and reversing

In this paper, we look at the concept of reversibility, that is, negating opposites, counterbalances, and actions that can be reversed. Piaget identified reversibility as an indicator of the ability to reason at a concrete operational level. We investigate to what degree novice programmers manifest the ability to work with this concept of reversibility by providing them with a small piece of code and then asking them to write code that undoes the effect of that code. On testing entire cohorts of students in their first year of learning to program, we found an overwhelming majority of them could not cope with such a concept. We then conducted think aloud studies of novices where we observed them working on this task and analyzed their contrasting abilities to deal with it. The results of this study demonstrate the need for better understanding our students' reasoning abilities, and a teaching model aimed at that level of reality.

New Curriculum History

"Rereading the historical record indicates that it is no longer so easy to argue that history is simply prior to its forms. Since the mid-1990s a new wave of research has formed around wider debates in the humanities and social sciences, such as decentering the subject, new analytics of power, reconsideration of one-dimensional time and three-dimensional space, attention to beyond-archival sources, alterity, Otherness, the invisible, and more. In addition, broader and contradictory impulses around the question of the nation - transnational, post-national, proto-national, and neo-national movements – have unearthed a new series of problematics and focused scholarly attention on traveling discourses, national imaginaries, and less formal processes of socialization, bonding, and subjectification. New Curriculum History challenges prior occlusions in the field, building upon and departing from previous waves of scholarship, extending the focus beyond the insularity of public schooling, the traditional framework of the self-contained nation-state, and the psychology of the schooled individual. Drawing on global studies, historical sociology, postcolonial studies, critical race theory, visual culture theory, disability studies, psychoanalytics, Cambridge school structuralisms, poststructuralisms, and infra- and transnational approaches the volume holds together not despite but because of differences and incommensurabilities in rereading historical records. Audience: Scholars and students in curriculum studies, history, education, philosophy, and cultural studies will be interested in these chapters for their methodological range, their innovations and their deterritorializations."--publisher website

Phoenix activity: Regulatory challenges and the law

Remedying the mischief of phoenix activity is of practical importance. The benefits include continued confidence in our economy, law that inspires best practice among directors, and law that is articulated in a manner such that penalties act as a sufficient deterrent and the regulatory system is able to detect offenders and bring them to account. Any further reforms must accommodate and tolerate legal phoenix activity. Phoenix activity pushes tolerance of entrepreneurial activity to its absolute limits. The wisest approach would be to front end the reforms so as to alleviate the considerable detection and enforcement burden upon regulatory bodies. There is little doubt that breach of the existing law is difficult and expensive to detect; and this is a significant burden when regulators have shrinking budgets and are rapidly losing feet on the ground. This front end approach may need to include restrictions on access to limited liability. The more limited liability is misused, the stronger the argument to limit access to limited liability. This paper proposes that such an approach is a legitimate next step for a robust and mature capitalist economy.

Experimental measurement of the mechanical properties of carotid atherothrombotic plaque fibrous cap

Eleven carotid atherothrombotic plaque samples were harvested from patients. Three samples that were highly calcified were discarded, while eight yielded results. The elastic properties of the material were estimated by fitting the measured indentation response to finite element simulations. The methodology was refined and its accuracy quantified using a synthetic rubber. The neo-Hookean form of the material model gave a good fit to the measured response of the tissue. The inferred shear modulus μ was found to be in the range 7-100 kPa, with a median value of 11 kPa. A review of published materials data showed a wide range of material properties for human atherothrombotic tissue. The effects of anisotropy and time dependency in these published results were highlighted. The present measurements were comparable to the static radial compression tests of Lee et al, 1991 [Structure-dependent dynamic behaviour of fibrous caps from human atherosclerotic plaques. Circulation 83, 1764-1770].

Foucault, Weber, neoliberalism and the politics of governmentality

This paper argues that Michel Foucault’s lectures that form The Birth of Biopolitics owe a considerable debt to the thought of Max Weber, particularly in their analysis of how different socio-legal regimes shape distinctive national forms of capitalist economies, and the role that is played by social and economic institutions in the shaping of individual identities. This is in contrast to a common interpretation of Foucault’s account of neoliberalism, which synthesizes his work into neo-Marxist notions of hegemony and capitalist domination. It also identifies Foucault’s approach to neoliberalism as an exploratory one, which considers insights into how a particular relationship between ideas and institutional practices may help in imagining socialist forms of government practice.

Andegraund : Istorija i mify leningradskoj neoficial'noj literatury

The history of the Leningrad underground is one of the key themes of late socialism. Samizdat, "black humour", religious syncretism, dissidence, apolitical bohemianism, the pathos of freedom of individuality and the mechanics of literature are closely interlinked with the cultural mythology of this passed epoch. Describing conceptions that, when taken together, form the contemporary understanding of unofficial culture, the author creates a historical portrait of this environment. Amongst the central figures here, there are well-known writers (Bitov, Brodsky, Dovlatov, Khvostenko, Krivulin) and literary activists who still await recognition. The analysis of works, many of which were only distributed in typewritten publications in the 1960s-1980s, gives a preliminary definition of the key factors that united the authors of the unofficial community. The book begins with a critique of the identification of the Soviet underground with political dissidence or with a society living in autonomous independence with regard to the state. Describing the historical development of the various names for this environment (the underground, samizdat, unofficial culture, podpolie and others), the author follows the genesis of the community from its appearance, in the years of "the Thaw", through to perestroika, when it dissolved. Taking the history of the publication of Bitov's "The Pushkin House" as an example, the concept of the unofficial is interpreted as a risky interaction with the authorities. Unofficial culture is then viewed as a late Soviet reflection of the Western underground in the 1950s-1960s. Unlike the radical-utopian-anarchistic source, it proclaimed a liberalist and democratic ideology in the context of the destruction of the socialist utopia. The historical portrait of the community is built up from the perceptions of its members regarding literature practice and rhetorical approaches, with the aid of which these perceptions are expressed. Taking typewritten publications as source material, four main representations are given: privacy, deviancy, criticism and irrationality. An understanding of literature as a private affair, neo-avant-garde deviancy in social and literary behaviour and the pathos of the critical relationship with officialdom and irrational message of literary work, comprise the basis for the worldview of unofficial authors, as well as the poetic system, genre preferences and dictums. An analysis of irrationality, based on the texts of Khvostenko and Bogdanov, leads to a review of the cultural mythologies that were crucial to the unofficial conception of the absurd. Absurd is an homonym. It contains ideas that are important for the worldview of unofficial authors and the poetics of their works. The irrationality of the Soviet order is reflected in the documentary nature of the satirical prose of Dovlatov. The existential absurd of Camus is perceived here as the pointlessness of social realities and the ontological alienation of man, while existentialist practices for consciousness in the "atmosphere of absurd" remain bracketed off. The third homonym of absurd - the conception of reality as an illusion - is a clear demonstration of religious syncretism, where neo-Christian ideas are interweaved with a modernized version of Hinduism, as taken from Rolland s books on Ramakrishna and Vivekananda. The unofficial community was influenced by the ideology of westernization. Even "the East" arrived here via French retellings and accounts. As a whole, unofficial Leningrad culture can be understood as a neo-modernist phenomenon which, unlike the western neo-modernism of the 1940s and 1950s, arose in the years of the Thaw and ended its existence in the mid-1980s.

Käsitteellisestä ruumiilliseen, sitaatiosta paikkaan - maalaustaide ja nykytaiteen historia

The dissertation "From Conceptual to Corporeal, from Quotation to Site: Painting and History of Contemporary Art" explores the state of painting in contemporary art and art theory since the 1960s. The purpose of the study is to re-consider the dominant "end of painting" -narrative in contemporary art history, which goes back to the modernist ideology of painting as a reductive, medium-specific form of art. Drawing on Michel Foucault´s concepts of discursive formation and archive, as well as Jean-Luc Nancy´s post-phenomenological philosophy on corporeality, I suggest that contemporary painting can be redefined as a discursive-sensuous practice. Instead of seeing painting as obsolete or over as an avantgarde art genre, I show that there have been alternative, neo-avantgardist ways of defining painting since the end of the 1960s, such as French artist Daniel Buren´s early writings on painting as "theoretical practice". Consequently, the tendency of the canonical Anglo-American contemporary art narratives to underestimate the historical and institutional codes of art can be questioned. This tendency can be seen, for example, in Rosalind Krauss´s influential theory on index. The study also reflects the relations between conceptual art and painting since the 1960s and maps recent theories of painting, which re-examine the genre´s possibilities after the modernist rhetoric. Concepts of "flatbed", "painting in the extended field", "as painting" and so on are compared critically with the idea of painting as discursive practice. It is also shown that the issues in painting arise from the contemporary critical art debate while the dematerialisation paradigm of conceptual art has dissolved. The study focuses on the corporeal-material-sensuous -cluster of meanings attached to painting and searches for its avantgardist possibilities as redefined by postfeminist and post-phenomenological discourse. The ideas of hierarchy of the senses and synesthesia are developed within the framework of Jean-Luc Nancy´s and Luce Irigaray´s thought. The parameters for the study have been Finnish painting from 1990 to 2002. On the Finnish art scene there has been no "end of painting" ideology, strictly speaking. The mythology and medium-specificity of modernism have been deconstructed since the mid-1980s, but "the archive" of painting, like themes of abstraction, formalism and synesthesia have been re-worked by the discursive practice of painting, for example, in the works of Nina Roos, Tarja Pitkänen-Walter and Jussi Niva.

A Literary Turn : Rethinking the Roles of Generalization and Theory in Anglo-American Moral Philosophy

This work investigates the role of narrative literature in late-20th century and contemporary Anglo-American moral philosophy. It aims to show the trend of reading narrative literature for purposes of moral philosophy from the 1970 s and early 80 s to the present day as a part of a larger movement in Anglo-American moral philosophy, and to present a view of its significance for moral philosophy overall. Chapter 1 provides some preliminaries concerning the view of narrative literature which my discussion builds on. In chapter 2 I give an outline of how narrative literature is considered in contemporary Anglo-American moral philosophy, and connect this use to the broad trend of neo-Aristotelian ethics in this context. In chapter 3 I connect the use of literature to the idea of the non-generalizability of moral perception and judgment, which is central to the neo-Aristotelian trend, as well as to a range of moral particularisms and anti-theoretical positions of late 20th century and contemporary ethics. The joint task of chapters 2 and 3 is to situate the trend of reading narrative literature for the purposes of moral philosophy in the present context of moral philosophy. In the following two chapters, 4 and 5, I move on from the particularizing power of narrative literature, which is emphasized by neo-Aristotelians and particularists alike, to a broader under-standing of the intellectual potential of narrative literature. In chapter 4 I argue that narrative literature has its own forms of generalization which are enriching for our understanding of the workings of ethical generalizations in philosophy. In chapter 5 I discuss Iris Murdoch s and Martha Nussbaum s respective ways of combining ethical generality and particularity in a philosophical framework where both systematic moral theory and narrative literature are taken seriously. In chapter 6 I analyse the controversy between contemporary anti-theoretical conceptions of ethics and Nussbaum s refutation of these. I present my suggestion for how the significance of the ethics/literature discussion for moral philosophy can be understood if one wants to overcome the limitations of both Nussbaum s theory-centred, equilibrium-seeking perspective, and the anti-theorists repudiation of theory. I call my position the inclusive approach .

Truth, Proof and Gödelian Arguments : A Defence of Tarskian Truth in Mathematics

One of the most fundamental questions in the philosophy of mathematics concerns the relation between truth and formal proof. The position according to which the two concepts are the same is called deflationism, and the opposing viewpoint substantialism. In an important result of mathematical logic, Kurt Gödel proved in his first incompleteness theorem that all consistent formal systems containing arithmetic include sentences that can neither be proved nor disproved within that system. However, such undecidable Gödel sentences can be established to be true once we expand the formal system with Alfred Tarski s semantical theory of truth, as shown by Stewart Shapiro and Jeffrey Ketland in their semantical arguments for the substantiality of truth. According to them, in Gödel sentences we have an explicit case of true but unprovable sentences, and hence deflationism is refuted. Against that, Neil Tennant has shown that instead of Tarskian truth we can expand the formal system with a soundness principle, according to which all provable sentences are assertable, and the assertability of Gödel sentences follows. This way, the relevant question is not whether we can establish the truth of Gödel sentences, but whether Tarskian truth is a more plausible expansion than a soundness principle. In this work I will argue that this problem is best approached once we think of mathematics as the full human phenomenon, and not just consisting of formal systems. When pre-formal mathematical thinking is included in our account, we see that Tarskian truth is in fact not an expansion at all. I claim that what proof is to formal mathematics, truth is to pre-formal thinking, and the Tarskian account of semantical truth mirrors this relation accurately. However, the introduction of pre-formal mathematics is vulnerable to the deflationist counterargument that while existing in practice, pre-formal thinking could still be philosophically superfluous if it does not refer to anything objective. Against this, I argue that all truly deflationist philosophical theories lead to arbitrariness of mathematics. In all other philosophical accounts of mathematics there is room for a reference of the pre-formal mathematics, and the expansion of Tarkian truth can be made naturally. Hence, if we reject the arbitrariness of mathematics, I argue in this work, we must accept the substantiality of truth. Related subjects such as neo-Fregeanism will also be covered, and shown not to change the need for Tarskian truth. The only remaining route for the deflationist is to change the underlying logic so that our formal languages can include their own truth predicates, which Tarski showed to be impossible for classical first-order languages. With such logics we would have no need to expand the formal systems, and the above argument would fail. From the alternative approaches, in this work I focus mostly on the Independence Friendly (IF) logic of Jaakko Hintikka and Gabriel Sandu. Hintikka has claimed that an IF language can include its own adequate truth predicate. I argue that while this is indeed the case, we cannot recognize the truth predicate as such within the same IF language, and the need for Tarskian truth remains. In addition to IF logic, also second-order logic and Saul Kripke s approach using Kleenean logic will be shown to fail in a similar fashion.

Feeding sorghum ergot (Claviceps africana) to sows before farrowing inhibits milk production

Objective: To assess the impact of feeding different amounts of sorghum ergot to sows before farrowing. Design: Fifty-one pregnant sows from a continually farrowing piggery were sequentially inducted into the experiment each week in groups of four to seven, as they approached within 14 days of farrowing. Diets containing sorghum ergot sclerotia within the range of 0 (control) up to 1.5% w/w (1.5% ergot provided 7 mg alkaloids/kg, including 6 mg dihydroergosine/kg) were randomly allocated and individually fed to sows. Ergot concentrations were varied with each subsequent group until an acceptable level of tolerance was achieved. Diets with ergot were replaced with control diets after farrowing. Post-farrowing milk production was assessed by direct palpation and observation of udders, and by piglet responses and growth. Blood samples were taken from sows on three days each week, for prolactin estimation. Results: Three sows fed 1.5% ergot for 6 to 10 days preceding farrowing produced no milk, and 87% of their piglets died despite supplementary feeding of natural and artificial colostrums, milk replacer, and attempts to foster them onto normally lactating sows. Ergot inclusions of 0.6% to 1.2% caused lesser problems in milk release and neo-natal piglet mortality. Of 23 sows fed either 0.3% or 0.6% ergot, lactation of only two first-litter sows were affected. Ergot caused pronounced reductions in blood prolactin, and first-litter sows had lower plasma prolactin than multiparous sows, increasing their susceptibility to ergot. Conclusion: Sorghum ergot should not exceed 0.3% (1 mg alkaloid/kg) in diets of multiparous sows fed before farrowing, and should be limited to 0.1 % for primiparous sows, or avoided completely.

Den brændende Fakkel : Om dobbeltgrebet i Knud Lyne Rahbeks liv og revolutionsroman

Professor Knud Lyne Rahbek was a novelist, playwright, poet, magazine editor, journalist, socialite person, host of the Bakkehus , historian, theatre manager, translator, publisher etc., but his versatility either side of 1800 is better known than read and more despised than understood. In terms of methodology, the thesis is based on biographical, historical and philological research, while at the same time making use of formalistic and close reading methods. This study begins and ends with 7th of February 1800, when Kamma and Knud Lyne Rahbek join the exiled P.A. Heiberg at the inn near Frederiksberg Castle. What falls between is an interpretation of Rahbek s works in the service of democracy, human rights and freedom of the press as a pragmatic navigation between activities - both subversive and legitimate. Posterity mistook this range as mere spinelessness, and Rahbek was relegated to the literary and historical margins as an anachronism and as a jack of all trades, who did not know what he really wanted and therefore flitted about in so many fields just to be present. But Rahbek s problem was not one of standpoint, but rather how to find a balance between totalizing attitudes and confrontations between rebellious idealism and deep-rooted absolutism, without foregoing his belief in enlightenment, humanism and tolerance. In this way, and also through his personal conduct, which at that time was seen as jovial bonhommie, he made his contribution to the development of modern democratic Denmark in the full awareness of a popular, peaceful and down-to-earth community. Rahbek s principal work about the event of the French Revolution, which provides the focus for the above, is Camill og Constance. Et Revolutions Skilderie (1799). For today s reader, the novel about the revolution is an obvious example of a historical novel, as it does not only provide fictionalized information about past events placing them in a generally accepted perspective of historical development, but also gives the characters qualities, which, in Rahbek s words, allows the real events to influence the fictional characters. From this point of view, the novel of the revolution has shifted the benchmark for the first real historical novel on the European literary scene back by fifteen years. Lacking the aura so easily foisted on fearless iconoclasts or tragic losers, Rahbek s contribution may seem modest in spite of its enormous volume; but only when it is not evaluated in its full context, which is the development of Denmark towards an international democratic society.

The micropolitics of management in universities: Challenges and opportunities

In recent decades, there has been a strong call by writers in education for alternative forms of leadership and management that are human centred and that value social cohesion, fairness, and democratic practices. Referred to by names such as transformative leadership (Shields, 2013) and ethical leadership (Starratt, 1996), those promoting these types of leadership argue for the use of “power as a moral force for the common good” (Duignan, 2007, p.12). In this chapter, our interest lies with managers in universities and how they use power in ethical and unethical ways. We consider some macro forces (e.g., globalisation, neo-liberal policies) that have impacted universities, making it difficult for managers to promote socially just and equitable practices. In particular, we examine the influence of managerialism—the application of private sector practices to the public sector—where the role of manager is not to question current practices, but to conform to performance targets, and to ensure compliance (O’Brien & Down, 2002). To come to an understanding of what might constitute ethical practices, we refer to the field of micropolitics as a way to help illuminate current practice and point to more positive ways of working.

Studies on Matrix Metalloproteinase (MMP-2, -9 and -14) and β2 Integrin Targeting as Potential Anticancer Therapeutics

Proteolytic enzymes, such as matrix metalloproteinases (MMP), are associated to the progression of several cancers. They degrade extracellular components, which helps tumors to expand and cancer cells to escape from the primary site. Of all MMPs, gelatinases (MMP-2 and -9) and membrane type-1 matrix metalloproteinase (MT1-MMP, MMP-14), in particular, are often associated to more aggressive types of head and neck carcinomas as well as to a poorer outcome in patient survival. Although therapies during the last decades have advanced, the mortality of the disease is still rather high and adjuvant therapies are searched for continuously. MMP-9 and MT1-MMP are also involved in neo-angiogenesis, which is necessary for tumor expansion. For this reason, we have identified synthetic peptides-targeting gelatinases and MT1-MMP, and have also evaluated their anticancer effects in vitro and in vivo. Antigelatinolytic peptides effectively inhibited tongue-carcinoma cell invasion and reduced the growth of xenografted tumors. In tumor samples of mice that were treated with antigelatinolytic peptides, the micro-vessel density was significantly reduced. We also identified a novel MT1-MMP targeting peptide and demonstrated that it exerted anticancer effects against several malignant cell lines in vitro. The effects of MT1-MMP inhibition on tongue-squamous cell carcinomas were evaluated by using xenograft tumors, which it effectively inhibited. Tranexamic acid was also demonstrated to inhibit tongue-squamous cell carcinoma invasion, most probably due to its ability to prevent the plasmin-mediated activation of proMMP-9. Leukocyte β2 integrins are another interesting option when evaluating targets for the therapeutic intervention of inflammatory conditions or malignancies of hematopoietic origin, since β2 integrins are expressed mainly by leukocytes. We identified a novel technique for screening small-molecule libraries against β2 integrins, and by using this technique we identified a novel αMβ2 integrin-binding chemical (IMB-10). IMB-10 significantly enhances leukocyte adhesion and inhibits their motility. We also demonstrated that IMB-10 can be used to inhibit inflammation and lymphoma growth in vivo. Interestingly, IMB-10 also reduced leukocyte tumor infiltration and inhibited tumor invasion.
