This book identifies core knowledge that educational leaders need to learn in pre-service preparation and throughout in-service professional development. The contributors discuss established pedagogical and experiential learning models as well as provocative new paradigms of their own to help prepare leaders and reinforce leadership effectiveness.

Two classic learning situations are critically reviewed and interpreted from a synergetic point of view: human learning of complex skills, and animal discrimination learning. Both show typical characteristics of nonlinear phase transitions: instability, fluctuations, critical slowing down and reorganisation. Plateaus in the acquisition curves of complex skills can be viewed as phases of arrested progress in which a reorganisation of simple skills is necessary before their integration into complex units is possible. Fluctuations and critical slowing down are expressed in instances (...) of "vicarious trial-and-error," which describe the oscillating behavior of rats at a choice point that is shown only just before discrimination learning is completed. It is concluded that education might pay more attention to the role of individual learning rhythms. (shrink)

Still the Heart of Darkness analyzes Richard Preston's best-selling account of an Ebola virus outbreak in Reston, Virginia in 1989. Through a textual examination of The Hot Zone, this essay demonstrates how Preston grounds his narrative about the threat of rare emerging viruses from the third world in terms of the colonialist discourse about Africa as the white man's grave, most notably Joseph Conrad's Heart of Darkness. By foregrounding previous outbreaks in Africa, Preston simultaneously darkens its landscape and inscribes the (...) Ebola filovirus as an external biological threat to Americans in a post-Cold War world with porous borders. (shrink)

The legal requirements and justifications for collecting patient-identifiable data without patient consent were examined. The impetus for this arose from legal and ethical issues raised during the development of a population-based disease register. Numerous commentaries and case studies have been discussing the impact of the Data Protection Act 1998 and Caldicott principles of good practice on the uses of personal data. But uncertainty still remains about the legal requirements for processing patient-identifiable data without patient consent for research purposes. This is (...) largely owing to ignorance, or misunderstandings of the implications of the common law duty of confidentiality and section 60 of the Health and Social Care Act 2001. The common law duty of confidentiality states that patient-identifiable data should not be provided to third parties, regardless of compliance with the DPA1998. It is an obligation derived from case law, and is open to interpretation. Compliance with section 60 ensures that collection of patient-identifiable data without patient consent is lawful despite the duty of confidentiality. Fears regarding the duty of confidentiality have resulted in a common misconception that section 60 must be complied with. Although this is not the case, section 60 support does provide the most secure basis in law for collecting such data. Using our own experience in developing a disease register as a backdrop, this article will clarify the procedures, risks and potential costs of applying for section 60 support. (shrink)

Top-down feedback does not benefit speech recognition; on the contrary, it can hinder it. No experimental data imply that feedback loops are required for speech recognition. Feedback is accordingly unnecessary and spoken word recognition is modular. To defend this thesis, we analyse lexical involvement in phonemic decision making. TRACE (McClelland & Elman 1986), a model with feedback from the lexicon to prelexical processes, is unable to account for all the available data on phonemic decision making. The modular Race model (Cutler (...) & Norris 1979) is likewise challenged by some recent results, however. We therefore present a new modular model of phonemic decision making, the Merge model. In Merge, information flows from prelexical processes to the lexicon without feedback. Because phonemic decisions are based on the merging of prelexical and lexical information, Merge correctly predicts lexical involvement in phonemic decisions in both words and nonwords. Computer simulations show how Merge is able to account for the data through a process of competition between lexical hypotheses. We discuss the issue of feedback in other areas of language processing and conclude that modular models are particularly well suited to the problems and constraints of speech recognition. Key Words: computational modeling; feedback; lexical processing; modularity; phonemic decisions; reading; speech recognition; word recognition. (shrink)

Teaching students to ask and answer questions is critically important if they are to engage in reasoned argumentation, problem-solving, and learning. This study involved 35 groups of grade 6 children from 18 classrooms in three conditions (cognitive questioning condition, community of inquiry condition, and the comparison condition) who were videotaped as they worked on specific inquiry-based science tasks. The study also involved the teachers in these classrooms who were audio-taped as they interacted with the children during these tasks. The results (...) show that while there were no significant differences in the children's explanatory behaviour across the two time periods, there were significant differences in the total verbal interactions between the children in the cognitive questioning condition and their peers in the community of inquiry and comparison conditions. Furthermore, the children in the cognitive questioning condition obtained higher reasoning and problem-solving scores than peers in the other conditions. Interestingly, while there were no significant differences between the teachers’ basic and extended mediating behaviours in the three conditions at Times 1 and 2, there was a significant difference in extended mediation behaviours with the teachers demonstrating nearly three times more extended mediation to promote students’ learning at Time 2 than they did at Time 1. Teacher intervention in providing guidance in how to interact during cooperative, inquiry-based science appears to be critical to helping students engage in higher-level thinking and learning.

Teaching children to ask and answer questions is critically important if they are to learn to talk and reason effectively together, particularly during inquiry-based science where they are required to investigate topics, consider alternative propositions and hypotheses, and problem-solve together to propose answers, explanations, and prediction to problems at hand. This study involved 108 students (53 boys and 55 girls) from seven, Year 7 teachers’ classrooms in five primary schools in Brisbane, Australia. Teachers were randomly allocated by school to one (...) of two conditions: the metacognitive questioning condition (Trained condition) or the prescriptive questioning condition (Untrained condition). Data on students’ discourse and reasoning and problem-solving (RP-S) were collected across Times 1 and 2. The results showed that while there were significant differences in the discourse categories of the students in the two conditions at Time 1, the only significant difference was in questioning behaviour at Time 2 with the students in the trained condition continuing to ask more questions than their untrained peers. Given that these students had been taught to specifically ask ‘thinking’ questions that probed and interrogated information, these results are not surprising. A follow-up examination of students’ discourse during their small group discussions illustrated how these students interacted with each other to probe and interrogate information by providing explanations and reasons to make their thinking explicit and by using analogies to verbally represent concepts they were trying to express. Results on the follow-up reasoning and problem-solving (RP-S) tasks indicated that students in the Trained and Untrained conditions improved their scores from Time 1 to Time 2 although the change was not significantly different between conditions.

Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

ABSTRACTThe negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates of (...) an unpresented word. Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately, individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay... (shrink)

Although researchers studying human speech recognition (HSR) and automatic speech recognition (ASR) share a common interest in how information processing systems (human or machine) recognize spoken language, there is little communication between the two disciplines. We suggest that this lack of communication follows largely from the fact that research in these related fields has focused on the mechanics of how speech can be recognized. In Marr's (1982) terms, emphasis has been on the algorithmic and implementational levels rather than on the (...) computational level. In this article, we provide a computational-level analysis of the task of speech recognition, which reveals the close parallels between research concerned with HSR and ASR. We illustrate this relation by presenting a new computational model of human spoken-word recognition, built using techniques from the field of ASR that, in contrast to current existing models of HSR, recognizes words from real speech input.

The central thesis of our target article is that feedback is never necessary in spoken word recognition. In this response we begin by clarifying some terminological issues that have led to a number of misunderstandings. We provide some new arguments that the feedforward model Merge is indeed more parsimonious than the interactive alternatives, and that it provides a more convincing account of the data than alternative models. Finally, we extend the arguments to deal with new issues raised by the commentators (...) such as infant speech perception and neural architecture. (shrink)

In 2012, a U.S. Institute of Medicine report called for a different approach to health care: “Left unchanged, health care will continue to underperform; cause unnecessary harm; and strain national, state, and family budgets.” The answer, they suggested, would be a “continuously learning” health system. Ethicists and researchers urged the creation of “learning health organizations” that would integrate knowledge from patient‐care data to continuously improve the quality of care. Our experience with an ongoing research study on atrial fibrillation—a trial known (...) as IMPACT‐AFib—gave us some insight into one of the challenges that will have to be dealt with in creating these organizations. Although the proposed educational intervention study placed no restrictions on what providers and health plans could do, the oversight team argued that the ethical principle of beneficence did not allow the researchers to be “bystanders” in relation to a control group receiving suboptimal care. In response, the researchers designed a “workaround” that allowed the project to go forward. We believe the experience suggests that what we call “bystander ethics” will create challenges for the kinds of quality improvement research that LHOs are designed to do. (shrink)

Programmatic concepts have elements that point in a valued direction or name a desired goal. We provide a detailed analysis of the nature of programmatic concepts and cite examples of the programmatic elements found in conceptions of scientific literacy. Next we describe what values underlie these elements and what theories of value might be brought to bear in assessing them. We present an analysis of approximately 70 conceptions of scientific literacy found in the literature since the year 2000. We identify (...) the goals that each of these conceptions of scientific literacy implies and uncover the programmatic elements that are used to justify these goals. Our purpose is to present a sufficiently wide range of views to have a good representation of goals and programmatic elements. Third, we point to a number of pitfalls in any attempt to make preferential selections among the programmatic elements of conceptions of scientific literacy. (shrink)

'The law imposes the duty of care: but the standard of care is a matter of medical judgment'. So says Lord Scarman, outlining the hitherto accepted 'Bolam' standard, in his recent speech in the House of Lords decision of Sidaway v Bethlem Royal Hospital, reflecting earlier judicial dicta suggesting that it is for the medical profession rather than the courts to determine whether or not a medical practitioner has achieved the required standard of care (1). It is suggested here that (...) this concept is bad in principle, and that the weight of judicial authority is against it. (shrink)

2. The equal status mentioned in Thesis 2 need not mean, "equally concrete" or "inclusive," but only, "equally real," where "real" means having a character of its own with reference to which opinions can be true or false. But becoming or process is alone fully concrete or inclusive, since if A is without becoming, and B becomes, then the togetherness of AB also becomes. A new constituent means a new totality. In this sense, becoming is the ultimate principle.

Hookups are uncommitted sexual encounters that range from kissing to intercourse and occur between individuals in whom there is no current dating relationship and no expressed or acknowledged expectations of a relationship following the hookup. Research over the last decade has begun to focus on hooking up among adolescents and young adults with significant research demonstrating how alcohol is often involved in hooking up. Given alcohol’s involvement with hooking up behavior, the array of health consequences associated with this relationship, as (...) well as its increasing prevalence from adolescence to young adulthood, it is important to determine the predictors and consequences associated with alcohol-related hooking up. The current review extends prior reviews by adding more recent research, including both qualitative and experimental studies (i.e. expanding to review more diverse methods), research that focuses on the use of technology in alcohol-related hookups (i.e. emerging issues), further develops prevention and intervention potentials and directions, and also offers a broader discussion of hooking up outside of college student populations (i.e., expanding generalization). This article will review the operationalization and ambiguity of the phrase hooking up, the relationship between hooking up and alcohol use at both the global and event levels, predictors of alcohol-related hooking up, and both positive and negative consequences, including sexual victimization, associated with alcohol-related hookups. Throughout, commentary is provided on the methodological issues present in the field, as well as limitations of the existing research. Future directions for research that could significantly advance our understanding of hookups and alcohol use are provided. (shrink)

Fragment 88 What is politics today? What is its relationship to the tradition from which it emerges? The questions are difficult ones to answer in part because contemporary politics seems so schizophrenic. In affluent Western countries politics is increasingly a matter of spectacle on the one hand and managed economies on the other. Hannah Arendt seems quite confirmed in her claim that the once-glorious public realm of appearance is fundamentally degraded when it is overrun by concerns more appropriate to the private realm, such as household management and gossip. If this "unnatural growth of the natural" [47] inclines us to nostalgia for a time when the two realms were more decisively separated, such nostalgia is likely intensified by the "ethnic cleansing," rape camps, and genocide that we now associate with names such as "Yugoslavia" and "Rwanda." But as improbable as any flight to the past may be, it is even less likely that the politics of that past could help us navigate the treacherous waters of our current technological society. I have in mind not only the familiar claim that the attempted genocides of our time are only made possible by quite modern forms of technology, organization, and experience, 1 but also recent scientific and "medical" advances. Consider just two: first, the corporate driven and controlled development of biotechnologies, in which huge multinationals are acquiring patents to genetic "information" such as "all human blood cells that have come from the umbilical cord of [any] newborn child." If there is any doubt that such developments will lead us to redefine the human being, these may be laid to rest by the case of John Moore, an Alaskan businessman who found his own body parts had been patented, without his knowledge, by the University of California at Los Angeles and licensed to the Sandoz Pharmaceutical Corporation [Rifkin 60-61]. So much for Locke's attempt to ground the institution of private property in the fact that "every Man has a Property in his own Person"! 2 In its place we seem to be moving [End Page 38] toward something more like the "logical synthesis of biology and economy" called for by the National Socialist Institut allemand in Paris in 1942 [Agamben, Homo Sacer 145]. A similar process of redefinition is already underway in the field of death, a phenomenon that scientists and lawyers are having a harder and harder time pinning down. Where once death was defined by the cessation of the movement of the heart and lungs, recent life support technologies have forced scientists to define death in terms of such technologies. Witness Doctor Norman Shumway's defense of the definition of death as brain death: "I'm saying that anyone whose brain is dead is dead. It is the one determinant that would be universally applicable, because the brain is the one organ that can't be transplanted" [163]. By implication, if and when technology is developed that allows for brain transplants, even those whose brains are "dead" will be brought back to some kind of life, perhaps as organ farms for others who are less ambiguously alive.Giorgio Agamben, from whose book Homo Sacer: Sovereign Power and Bare Life I take both this last grisly example and its analysis, argues that, contrary to appearances, such developments do not represent a radical break with the tradition. His analysis both builds upon and corrects Michel Foucault's claim that politics in our time is constituted by disciplines of normalization and subjectification that Foucault labels "bio-power." For Foucault, biopower is fundamentally modern. "What might be called a society's 'threshold of modernity,'" he writes, "has been reached when the life of the species is wagered... (shrink)

This study examines how hunger narratives and performances contribute to a reconsideration of neglected or prohibited domains of thinking which only a full confrontation with the body's heterogeneity and plasticity can reveal. From literary motif or psychosomatic symptom to revolutionary gesture or existential malady, the double crux of hunger and disgust is a powerful force which can define the experience of embodiment. Kafka's fable of the "Hunger Artist" offers a matrix for the fast, while its surprising last-page revelation introduces disgust (...) as a correlative of abstinence, conscious or otherwise. Grounded in Kristeva's theory of abjection, the figure of the fraught body lurking at the heart of the negative grotesque gathers precision throughout this study, where it is employed in a widening series of contexts: suicide through overeating, starvation as self-performance or political resistance, the teratological versus the totalitarian, the anorexic harboring of death. In the process, writers and artists as diverse as Herman Melville, Percy Bysshe Shelley, Christina Rossetti, George Orwell, Knut Hamsun, J.M. Coetzee, Cindy Sherman, Pieter Breughel, Marina Abramovic, David Nebreda, Paul McCarthy, and others are brought into the discussion. By looking at the different acts of visceral, affective, and ideological resistance performed by the starving body, this book intensifies the relationship between hunger and disgust studies while offering insight into the modalities of the "dark grotesque" which inform the aesthetics and politics of hunger. It will be of value to anyone interested in the culture, politics, and subjectivity of embodiment, and scholars working within the fields of disgust studies, food studies, literary studies, cultural theory, and media studies.
