One of the more telling symptoms of the postmodern condition is the tendency of criticism to renounce any claim to explanatory or evaluative competence vis-à-vis its objects, and in some cases even to deny that it differs from those objects. This is especially evident in American deconstructionists of the Yale school, who have, with Derrida, rediscovered Nietzsche's insight that all language, whatever the genre, is inescapably metaphorical. From the admitted difficulty of drawing absolute ontological distinctions between the language of literature (...) and that of criticism, these critics infer that the attempt to maintain even a generic division between the two languages is at best a convenient fiction, at worst a repressive one.

Is the essay literature or philosophy? A form of art or a form of knowledge? The contemporary essay is torn between its belletrist ancestry and its claim to philosophical legitimacy. The Spanish philosopher Eduardo Nicol captured the genre's uncertain status when he dubbed it “almost literature and almost philosophy” (Nicol 1961:207). The problem is hardly a new one. It goes back to what Plato called the “ancient quarrel” between poetry and philosophy, and more recently to the German Romantic theorist, Friedrich (...) Schlegel, who called for a mode of criticism which would be at once philosophical and poetic. But today, when the status of critical discourse is up for grabs, reflecting the crisis of knowledge in the universities, the question of the essay takes on a new urgency. Now the predominant form of writing in the human sciences, it cannot avoid the challenge to define itself according to the prevailing standards of scientific knowledge and method. (shrink)

A photoaffinity analog of cGMP has been used to biochemically identify a new ligand-binding subunit of the retinal rod cGMP-activated ion channel, as well as amino acids in contact with cGMP in the original subunit. Covalent tethering of this probe to channels in excised menbrane patches has revealed a functional heteogeneity in the ligand-binding sites that may arise from the two biochemically identified subunits.

We report an empirical study of elementary algebra errors, conducted in three separate schools. The errors are diagnosed using mal‐rules, as proposed by Sleeman (1984, 1,985). Our analysis uncovers the following properties of algebra mal‐rules: The frequency of mal‐rules is severely skewed, there are many infrequent mal‐rules and few frequent ones; mal‐rules are very unstable, students typically use mal‐rules very irregularly; different mal‐rules have explanatory power in different schools (many of our most powerful mal‐rules are previously unreported); mal‐rule diagnosis Is (...) more successful with more skilled students; students' confidence ratings do not partition the total set of mal‐rules, every mal‐rule we find is associated with high confidence ratings by at least one student. The Implications of our data for cognitive theories of error generation are discussed. Contrary to commonplace assumptions, we argue that It is impossible to make a clear distinction between slips and mistakes; most errors depend on properties of the knowledge base and the cognitive architecture. Errors In a procedural skill cannot be assumed to be purely syntactic In orgin. (shrink)

New Zealand is a multilingual and multicultural society, where English, Maori, and the New Zealand sign language are designated as its official languages. However, some heritage languages are also taught either within or outside the national education system. During the past decade, an increasing number of students have chosen Mandarin Chinese as an additional language because of its fast-growing importance. To date, studies regarding CAL are mainly based on the mainstream Chinese programs or online platforms, with less attention paid to (...) other types of teaching contexts where there also exist many potential challenges awaiting teachers. To fill in this gap, this study, based on a teaching program consisting of two families in New Zealand, explored the trajectories of a CAL teacher’s emotional labor for 47 weeks to understand how she managed her emotions when she taught the language as well as balanced the relationship among the three parties: the institution, the two families, and herself. Narrative inquiry was used as a methodological approach. The data involved written and spoken narratives. Using inductive and deductive thematic analysis, findings revealed her different understandings of the emotional labor in the two families, respectively, during the program. Further analysis of the data revealed some factors that impacted her emotional labor and how they impacted her teaching in a family-based context. We concluded our study with a discussion of the implications of these findings for teaching CAL in similar contexts. (shrink)

Both RalA and RalB interact with the ubiquitous calcium sensor, calmodulin (CaM). New structural and biophysical characterisation of these interactions strongly suggests that, in the native membrane‐associated state, only RalA can be extracted from the membrane by CaM and this non‐canonical interaction could underpin the divergent signalling roles of these closely related GTPases. The isoform specificity for RalA exhibited by CaM is hypothesised to contribute to the disparate signalling roles of RalA and RalB in mitochondrial dynamics. This would lead to (...) CaM shuttling RalA to the mitochondrial membrane but leaving RalB localisation unperturbed, and in doing so triggering mitochondrial fission pathways rather than mitophagy. (shrink)

Many clinical and psychological constructs are conceptualized to have multivariate higher-order constructs that give rise to multidimensional lower-order traits. Although recent measurement models and computing algorithms can accommodate item response data with a higher-order structure, there are few measurement models and computing techniques that can be employed in the context of complex research synthesis, such as meta-analysis of individual participant data or integrative data analysis. The current study was aimed at modeling complex item responses that can arise when underlying domain-specific, (...) lower-order traits are hierarchically related to multiple higher-order traits for individual participant data from multiple studies. We formulated a multi-group, multivariate higher-order item response theory (HO-IRT) model from a Bayesian perspective and developed a new Markov chain Monte Carlo (MCMC) algorithm to simultaneously estimate the (a) structural parameters of the first- and second-order latent traits across multiple groups and (b) item parameters of the model. Results from a simulation study support the feasibility of the MCMC algorithm. From the analysis of real data, we found that a bivariate HO-IRT model with different correlation/covariance structures for different studies fit the data best, compared to a univariate HO-IRT model or other alternate models with unreasonable assumptions (i.e., the same means and covariances across studies). Although more work is needed to further develop the method and to disseminate it, the multi-group multivariate HO-IRT model holds promise to derive a common metric for individual participant data from multiple studies in research synthesis studies for robust inference and for new discoveries.

Constantine, the first Christian Emperor, bequeathed war against Persia to his son Constantius, a legacy which haunted the next two decades, culminating in Julian′s debacle in 363. Much has been written on the timing, motives, and strategy of these campaigns but the same role model appears at their beginning and end: Alexander the Great. Here, I wish to re-examine the evidence for his presence: recent scholarship has minimized it at one end and maximized at the other.

Rousseau argued forcefully for the superiority of a life lived in accordance with “the simplest impulses of nature,” but his complex (somewould say contradictory) understanding of the relationship between humans and “nature” is rarely cited as a source of inspiration by those seeking to reform the human relationship with the natural world. We argue that the complexities of Rousseau's political thought illuminate important connections between his works and the programs put forth by deep ecology. In Part One, we explore the (...) theoretical connections between Rousseau's account of the human fall from nature and major works of radical environmentalism. In Part Two, we offer suggestions for a reconsideration of Rousseau's work that may illuminate the paradoxical political requirements of deep ecology's recommendations for a more ecological human life. We hope to illustrate howa careful reading of Rousseau'swork may serve as the basis for fruitful questioning of environmentalist thought. (shrink)

Over the past several decades, nurses have been increasingly theorizing about the relationships between culture, health, and nursing practice. This culture theorizing has changed over time and has recently been subject to much critical examination. The purpose of this paper is to identify the challenges impeding nurses' ability to build theory about the relationships between culture and health. Through a historical overview, I argue that continued support for the essentialist view of culture can maintain a limited view of complex race (...) relations. I also argue that attempts to apply culture theory, without knowledge of important historical, political, and economic factors, has often resulted in oversimplified versions of what was originally intended. Furthermore, I argue that individual-level interventions alone will be insufficient to address health inequities related to culture. Despite new critical conceptualizations of culture and the uptake of cultural safety, nursing scholars must better address the broader organizational, population, and political interventions needed to address inequities in health. I conclude with suggestions for how nurses might proceed with culture theorizing given these challenges. (shrink)

The life-long correspondence of David K. Lewis, one of the most influential philosophers of the twentieth century, reveals the development, breadth, and depth of his philosophy in its historical context. The first of this two volume collection of letters focuses on his contributions to metaphysics, arguably where he made his greatest impact.

Computational models of learning provide an alternative technique for identifying the number and type of chunks used by a subject in a specific task. Results from applying CHREST to chess expertise support the theoretical framework of Cowan and a limit in visual short-term memory capacity of 3–4 looms. An application to learning from diagrams illustrates different identifiable forms of chunk.

We discuss the relation of the Theory of Event Coding (TEC) to a computational model of expert perception, CHREST, based on the chunking theory. TEC's status as a verbal theory leaves several questions unanswerable, such as the precise nature of internal representations used, or the degree of learning required to obtain a particular level of competence: CHREST may help answer such questions.
