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)

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.

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)

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 second of this two volume collection focuses on his contributions to philosophical questions of language, mind, and epistemology.

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.

David K. Lewis (1941-2001) was unquestionably one of the most important analytic philosophers of the twentieth century, writing papers and books, largely but not exclusively in metaphysics, that set the intellectual agenda across a huge variety of topics in the last three decades. Some twenty years after his death, this collection of essays reflects the historical importance of Lewis's work by bringing together a range of scholarly reflections on his work. The essays consider a range of topics including the nature (...) of metaphysics, the epistemology of necessary truths, possibility, naturalness, supervenience, time travel, causation, semantics, and ethics. Several of them draw on an exciting new body of material in the Lewisian corpus, his extensive correspondence, recently published in two volumes (OUP, 2020). The wide-ranging topics of these essays illustrate the impressive extent of Lewis's thought and his reach across most areas of analytic philosophy. The chapters collected in this volume adds to the increasing literature on the philosophy of David K. Lewis and will be an important book for those examining his role in the history of analytic philosophy. (shrink)

Distinguished contributors take up eminent scholar Daniel R. Schwarz’s reading of modern fiction and poetry as mediating between human desire and human action. The essayists follow Schwarz’s advice, “always the text, always historicize,” thus making this book relevant to current debates about the relationships between literature, ethics, aesthetics, and historical contexts.

Substantial research efforts have been devoted to developing a cure for autism, but some advocates of people with autism claim that these efforts are misguided and even harmful. They claim that there is nothing wrong with people with autism, so there is nothing to cure. Others argue that autism is a serious and debilitating disorder and that a cure for autism would be a wonderful medical breakthrough. Our goal in this essay is to evaluate what assumptions underlie each of these (...) positions. We evaluate the arguments made on each side, reject those that are implausible and then highlight the key assumptions of those that remain. (shrink)

Decentralized autonomous organizations (DAOs) are a new, rapidly-growing class of organizations governed by smart contracts. Here we describe how researchers can contribute to the emerging science of DAOs and other digitally-constituted organizations. From granular privacy primitives to mechanism designs to model laws, we identify high-impact problems in the DAO ecosystem where existing gaps might be tackled through a new data set or by applying tools and ideas from existing research fields such as political science, computer science, economics, law, and organizational (...) science. Our recommendations encompass exciting research questions as well as promising business opportunities. We call on the wider research community to join the global effort to invent the next generation of organizations. (shrink)

In this paper, we explore best practices for asynchronous discussions in graduate online bioethics education. We explain that online approaches have advantages and challenges in contrast to in-person discussions. Online challenges are lack of visual or auditory cues and technical access. Advantages include extended opportunities for specific focus, thoughtful reflection, and critical review. We found no significant review of related best practices in bioethics. Our more general literature review of graduate education and online approaches, plus experience in our own bioethics (...) graduate program, suggest provisional best practices that we detail. We reason that online graduate discussion provisionally should aim for a “community of inquiry” framework that incorporates cognitive, social, and teaching “presences,” as well as a learning presence. However, we also note unresolved concerns about whether the framework sufficiently addresses learning, is complete, and captures communicative functions. Drawing further on the literature, we also suggest best practices for instructor feedback to students about their discussion performance, including that remarks should be timely and specific. Summaries from two courses in our graduate bioethics program illustrate how we implement discussion strategies. Finally, we review assessment strategies and suggest that embedded formative assessments in discussion support and demonstrate deeper learning. Limitations in generalizability include that our review targets asynchronous and text-based online discussion, our program assessments do not necessarily detail best practices, student expectations and approaches could be rather particular to our program, and specific bioethics content in principle could alter best practices.

How might artificial neural networks (ANNs) inform cognitive science? Often cognitive scientists use ANNs but do not examine their internal structures. In this paper, we use ANNs to explore how cognition might represent musical properties. We train ANNs to classify musical chords, and we interpret network structure to determine what representations ANNs discover and use. We find connection weights between input units and hidden units can be described using Fourier phase spaces, a representation studied in musical set theory. We find (...) the total signal coming through these weighted connection weights is a measure of the similarity between two Fourier structures: the structure of the hidden unit's weights and the structure of the stimulus. This is surprising because neither of these Fourier structures is computed by the hidden unit. We then show how output units use such similarity measures to classify chords. However, we also find different types of units—units that use different activation functions—use this similarity measure very differently. This result, combined with other findings, indicates that while our networks are related to the Fourier analysis of musical sets, they do not perform Fourier analyses of the kind usually described in musical set theory. Our results show Fourier representations of music are not limited to musical set theory. Our results also suggest how cognitive psychologists might explore Fourier representations in musical cognition. Critically, such theoretical and empirical implications require researchers to understand how network structure converts stimuli into responses. (shrink)

Why should the work of the ancient and the medievals, so far as it relates to nature, still be of interest and an inspiration to us now? The contributions to this enlightening volume explore and uncover contemporary scholarship's debt to the classical and medieval past. Thinking About the Environment synthesizes religious thought and environmental theory to trace a trajectory from Mesopotamian mythology and classical and Hellenistic Greek, through classical Latin writers, to medieval Christian views of the natural world and our (...) relationship with it. The work also offers medieval Arabic and Jewish views on humanity's inseparability from nature. The volume concludes with a study of the breakdown between science and value in contemporary ecological thought. Thinking About the Environment will be a invaluable source book for those seeking to address environmental ethics from a historical perspective. (shrink)

Negative acknowledgement is an impression management technique that uses the admission of an unfavourable quality to mitigate a negative response. Although the technique has been clearly demonstrated, the underlying process is not well understood. The current research identifies a key mediator and moderator while also demonstrating that the effect extends beyond the specific acknowledged domain to the overall evaluation of a target object. The results of study 1 indicate that negative acknowledgement works through mitigating negatively valenced cognitive responses. People who (...) are presented with a negative acknowledgement are less likely to counterargue when forming an evaluation. The results of study 2 reveal that individual differences in need for structure impact the effectiveness of the technique. People who are high in need for structure are more susceptible to the effect presumably because of their desire for easy-to-use information that aids the formation and maintenance of simple knowledge structures.

The paper offers a critical examination of Jennifer Hornsby's view that actions are internal to the body. It focuses on three of Hornsby's central claims: (P) many actions are bodily movements (in a special sense of the word “movement”) (Q) all actions are tryings; and (R) all actions occur inside the body. It is argued, contra Hornsby, that we may accept (P) and (Q) without accepting also the implausible (R). Two arguments are first offered in favour of the thesis (Contrary-R): (...) that no actions occur inside the body. Three of Hornsby's arguments in favour of R are then examined. It is argued that we need to make a distinction between the causes and the causings of bodily movements (in the ordinary sense of the word “movement”) and that actions ought to be identified with the latter rather than the former. This distinction is then used to show how Hornsby's arguments for (R) may be resisted. (shrink)

Uncertainty and emotion are an inevitable part of everyday life and play a vital role in mental health. Yet, our understanding of how uncertainty and emotion interact is limited. Here, an online survey was conducted to examine whether uncertainty evokes and modulates a range of negative and positive emotions. The data show that uncertainty is predominantly associated with negative emotional states such as fear/anxiety. However, uncertainty was also found to modulate a variety of other negative and positive emotional states, depending (...) on the valence of an anticipated outcome and the sub parameter of uncertainty. Uncertainty increased the intensity of negative emotional states and decreased the intensity of positive emotional states. These findings support prior research suggesting that uncertainty is aversive and associated with negative emotional states such as fear and anxiety. However, the findings also revealed that uncertainty is involved in eliciting and modulating a wide array of emotional phenomena beyond fear and anxiety. This study highlights an opportunity for further study of how uncertainty and emotion interactions are conceptualised generally and in relation to mental health. (shrink)

Ce texte replace les groupes et penseurs marxistes ou ceux relevant, plus largement, d’un socialisme réformiste dans l’ensemble des courants de l’opposition en RDA entre 1945 et 1990 et cherchent à mesurer leur impact. En procédant chronologiquement, il évoque la résistance, essentiellement antimarxiste des années 1940 et 1950, ainsi que les conflits au sein du SED lors du soulèvement du 17 juin 1953, puis l’émergence d’un courant réformiste à partir de 1956 qui évolue vers la dissidence chez certains (W. Harich, (...) R. Havemann, W. Biermann, R. Bahro). À partir du printemps de Prague en 1968, puis de l’affaire Biermann en 1976, on assiste à un phénomène consistant à retourner les textes marxistes-léninistes contre le SED. Le mouvement citoyen qui se constitue à partir de 1976 compte quelques groupes d’inspiration marxiste qui se retrouvent, au moment de la révolution de 1989, sous la bannière de Gauche unie ( Vereinigte Linke ).

The Long Fifteenth Century is intended as a companion volume to Douglas Gray's ground-breaking Oxford Book of Late Medieval Verse and Prose and incorporates a bibliography of his published writings. Gray's anthology revolutionized critical appreciation of English and Scottish literature of the `long fifteenth century' from the death of Chaucer to the Reformation, but the literature of the period as a whole remains much under-read, undervalued, and under-studied. The contributors to this volume, all leading scholars in the field, bring to (...) the fore the power of underrated writers, restore to the period writings often attributed to other centuries, open up new possibilities in neglected genres, offer radical rereadings of some more familiar works, and demonstrate how closely the literature of the period is bound up with political and social conditions. Written in honour of Douglas Gray, to mark his long and distinguished tenure of the J.R.R. Tolkein Professorship of English Literature and Language at Oxford university, the 15 essays in this volume portray the long fifteenth century as a major period of literature in its own right. They provide a comprehensive survey of fifteenth-century literature in print, from the morality play to the ballad, verse forms to prose romances, including Chaucer, Lydgate, Skelton, and Hoccleve, along with essays on the Middle French Poets and Scottish writings of the period.

The aim of the study was to compare the acute effects of traditional resistance training and superset training on training duration, training volume and different perceptive measures. Twenty-nine resistance-trained participants performed a whole-body workout traditionally and as supersets of exercises targeting different muscle groups, in a randomized-crossover design. Each session was separated by 4–7 days, and consisted of eight exercises and three sets to failure. Training duration and number of repetitions lifted were recorded during the sessions. Rate of perceived exertion (...) for effort, rate of perceived exertion for discomfort, session displeasure/pleasure, and exercise enjoyment were measured 15 min after each session. Forty-eight hours after the final session participants reported which session they preferred. The superset session led to significantly higher values for RPE and RPD and tended to be higher for sPDF, i.e., more pleasurable, compared to the traditional session. There was no difference in EES. The traditional session led to significantly increased training volume and lasted 23 min longer than the superset session. Eighteen of the participants preferred the superset session, while 11 preferred the traditional session. In conclusion, performing a whole-body workout as a superset session was more time-efficient, but reduced the training volume and was perceived with greater exertion for effort and discomfort than a traditional workout.
