In an attempt to discover the facial action units for affective states that occur during complex learning, this study adopted an emote-aloud procedure in which participants were recorded as they verbalised their affective states while interacting with an intelligent tutoring system (AutoTutor). Participants’ facial expressions were coded by two expert raters using Ekman's Facial Action Coding System and analysed using association rule mining techniques. The two expert raters received an overall kappa that ranged between.76 and.84. The association rule mining analysis (...) uncovered facial actions associated with confusion, frustration, and boredom. We discuss these rules and the prospects of enhancing AutoTutor with non-intrusive affect-sensitive capabilities. (shrink)

Academic debate on the strategic importance of women corporate directors is widely recognized and still open. However, most corporate boards have only one woman director or a small minority of women directors. Therefore they can still be considered as tokens. This article addresses the following question: does an increased number of women corporate boards result in a build up of critical mass that substantially contributes to firm innovation? The aim is to test if ‘at least three women’ could constitute the (...) desired critical mass by identifying different minorities of women directors (one woman, two women and at least three women). Tests are conducted on a sample of 317 Norwegian firms. The results suggest that attaining critical mass – going from one or two women (a few tokens) to at least three women (consistent minority) – makes it possible to enhance the level of firm innovation. Moreover, the results show that the relationship between the critical mass of women directors and the level of firm innovation is mediated by board strategic tasks. Implications for both theory and practice, and future research directions are discussed. (shrink)

The paper argues that the theme of cultural and racial oppression is present throughout Freire’s work. In particular, it explores Paulo Freire’s contribution to the discussion of colonialism and decolonization. To this purpose, first of all it takes into consideration some writings elaborated between the end of the 1950s and the 1970s, enhancing the dialogue with authors such as Albert Memmi, Frantz Fanon and Amílcar Cabral. Then it focuses on concepts which, although not directly linked to the analysis of colonialism, (...) can help reinvent and expand Freire’s proposal in a decolonial key. The last part is dedicated to Freire’s influence on decolonial pedagogy and intercultural critical pedagogy, developed in recent decades starting from the Latin American context. (shrink)

This book uses philosophy, psychology, and autobiography in an innovative exploration of the nature and evolution of self-knowledge. Topics include the impact of others, the role of fantasy, the construction of self-image, and playing roles; the second part of the book explores how self-understanding evolves through friendship.

I medievisti ovviamente più degli antichisti - osserva G. Duby - sono strana gente simile agli antropologi, persone che evadono dal loro presente partendo per l'XI secolo invece che per Samoa o per le isole Trobriand e fuggono dal loro mondo per sprofondare nelle radici.

The present essay aims first at clarifying Werner Beierwaltes’ understanding of Neoplatonism at large as the accomplishment of Greek philosophy pursued by Plotinus and coherently developed by Proclus. It seeks secondly to locate Beierwaltes’ remarkable effort to trace the “Wirkungsgeschichte” of Neoplatonism. Focus has been placed, thirdly on his understanding of Dionysius Areopagita as the effective mediator of Neoplatonic issues in the Latin philosophical tradition long before the rediscovery of Proclus in the 13. century. Beierwaltes’ understanding of Dionysius’ “Christian Neoplatonism” (...) as a lucky instance of “Hellenization of Christianity” is finally compared with different exegesis provided by Ivánka and Balthasar in the years immediately preceding Beierwaltes’ remarkable Proclus-monography of 1965.

Over the last decade, the efforts towards unraveling the complex interplay between the brain, body, and environment have set a promising line of research that utilizes neuroscience to study human performance in natural work contexts such as aviation. Thus, a new discipline called neuroergonomics is holding the promise of studying the neural mechanisms underlying human performance in pursuit of both theoretical and practical insights. In this work, we utilized a neuroergonomic approach by combining insights from ecological psychology and embodied cognition (...) to study flight expertise. Specifically, we focused on the Mirror Neuron system as a key correlate for understanding the interaction between an individual and the environment, suggesting that it can be used to index changes in the coupling of perception-action associated with skill development.In this study, we measured the EEG mu suppression as a proxy of the Mirror Neuron system in experts (pilots) and novices while performing a distance estimation task in a landing scenario. To survey the specificity of this measure, we considered central, parietal and occipital electrode pools and analyzed alpha (8-13 Hz) and beta (18-25 Hz) rhythm bands. We hypothesized that in experts vs. novices, specific neural sensorimotor brain activity would underpin the connection between perception and action in an in-flight context. Preliminary results indicate that alpha and beta suppression was area-specific irrespective of groups, present in the central electrodes placed over the motor areas. Group analysis revealed that specifically alpha mu rhythm, but not beta, was significantly more suppressed in pilots vs. novices. Complementing these findings we found a trend in which the strength of mu suppression increased with the sense of presence experienced by the pilots. Such sensorimotor activation is in line with the idea that for a pilot, a distance judgment is intimately associated with the function of landing. This reflects the ability to use optical invariants to see the world in terms of the capabilities of the aircraft (e.g., reachability and glide angle).These preliminary findings support the role of embodied simulation mechanisms in visual perception and add important insights into a practical understanding of flight expertise, suggesting sensorimotor mechanisms as potential neuro-markers.

The termTabulae Iliacaeis conventionally applied to twenty low reliefs scattered through museums from Warsaw to New York. The common name conceals a bewildering artistic farrago: the earliestTabula, theTabula Iliaca Capitolina, is mid-Augustan, the latest late Antonine. Five of theTabulaebear the name Theodorus and I shall argue that he is the craftsman responsible for their execution. Where provenance is known, it is always Rome or the Roman Campagna. The materials of theTabulaevary widely: most, but not all, are of some sort of (...) marble, white, yellow, and Giallo Antico. Little can be said of their size, for not one survives complete. It would appear, however, that the largest rectangularTabula, the calcite 1 A, was originallyc.25 cm by 42 cm. Two, portraying the Shield of Achilles, were circular and 5O may have had a radius of 20 cm. The nameIliacaeis appropriate only in as much as eleven out of twentyTabulaeportray episodes from theIliad and six the Sack of Ilium; others, however, represent Alexander's victory at Arbela and the apotheosis of Hercules. What theTabulaedo display in common is a combination of low reliefs in miniature and inscriptions, often extensive and not always on the same topic as the reliefs. In ancient art, only the Megarian bowls stand comparison, and their ratio of text to illustration is substantially lower. (shrink)

Neural Stem Cells (NSC) are present in the developing and adult CNS. In both the embryonic and adult neurogenic regions, β1 integrins may act as sensors for the changing extracellular matrix. Here we highlight the integrative functions that β1 integrins may play in the “niche” by regulating NSC growth factor responsiveness in a timely and spatially controlled manner. β1 integrins may provide NSC with the capacity to react to a dynamic “niche”, and to respond adequately by either remaining as stem (...) cells or by differentiating and migrating away to shape the developing cortex. © 2005 Wiley Periodicals, Inc.

If the Iliadic Aeneas has a fault, it is that he fails to die: 20.302 . In Homer, he is not memorable, but closer inspection reveals a warrior of authentic distinction.

This paper presents qualitative research that focus on the Reading Groups. The aim is to understand the values of reading and discussing books in group, during the months of lockdown, caused by the Covid-19 health emergency. Using written and structured interviews, we collected the experiences of 73 adult participants in Reading Group in Milan and Bergamo provinces. The results show how, even by the unusual online mode, the Reading Group was a way to defend oneself from the pain of reality, (...) a space of relationship in isolation and a possibility of self-assertion, in situation of strong limitation of individual freedom. Starting from the analysis of what happened, this study wants to outline the potential of Reading Groups as pedagogical environments to produce change. (shrink)

In recent years, the concept of the Anthropocene has summoned such an archipelago of senses that the academic debate related to this term, which initially emerged in the natural sciences, has since penetrated the fields of philosophy, economy, history, and sociology. To draw a possible cartography of the Anthropocene, we wish before anything else to emphasize the intrinsic connection between the debate on the Anthropocene and the theme of climate change, and, more generally, of the environmental crisis. We will attempt (...) to show, also, how a Merleau-Pontyan philosophy that is constitutively dedicated to overcoming dichotomies – philosophy and non-philosophy, nature and culture, subject and object – can provide a valuable methodological and ontological support for the study of the environmental question and the ecological crisis. This philosophy belongs, in its own right, among the non-sad philosophies for thinking climate change. (shrink)

Mr. Harrison's critique of my article in JRS 63 is conducted with characteristic learning and subtlety. He has pointed out much that I ought to have observed. But I remain altogether unconvinced: Harrison objects to my preferring a close local sense for his , hinc , repetit and revehis because in comparison with the distance from Troy, even the 100-odd miles from Cortona to the scene of action—let alone the 50-odd miles from Tarquinii—count as ‘loca’.

This paper is a critique of some research methods evident in contemporary nursing literature. The arguments derive from critical‐feminist, humanist and ethical perspectives. As a consequence of investigating specific aspects of scientific method, an approach to research that is congruent with values intrinsic to an holistic approach to nursing practice is articulated. Such methodologies also render problematic with status quo power relations between nurses and other health professionals, as well as between nurses and patients. The central themes in this paper (...) are: the absence of overt conceptual frameworks; an avoidance of complex social contexts within which research subjects live; an apparent lack of empathy; and an apolitical articulation of research problems and data analyses. All four of these difficulties may be traced to scientific methodology by many researchers. Most nurse researchers may not actually adhere to this technique, but I propose that they have been informed by belief systems associated with scientific methodology and diat these have dire consequences for the discipline of nursing. A key argument is diat the apparent lack of conceptual frameworks in the majority of nursing research is due to the epistemology, which therefore provides a pre‐existing, non‐declared conceptual framework, that is incorporated into the research by drawing upon scientific mediodology. A further argument is diat scientific, or scientistic, ways of approaching situations are antithetical to nursing values and to constructive social change for the benefit of patients, nursing and nurses.

Understanding the spread of national public policies to increase the percentage of women on boards is often presented using different types of institutional theory logic. However, the importance of the political games influencing these decisions has not received the same attention. In this article, we look beyond the institutional setting by focusing on the role of actors. We explore processes that include who the critical actors that drive and determine these policies are, and what motivates them to push for change. (...) We employ a processual design approach using a longitudinal country-comparative case study exploring the case of Norway, England, Germany and Italy. We map the political games, both inside and outside legislative areas, including the micro-politics among various actors and groups of actors in the selected countries. Data are collected through participation observations, interviews and text analyses. The study contributes by filling important gaps in the literature by embedding the discussion about women on boards in politicking and national public policies and by introducing dynamic perspectives. Finally, by using a processual design approach, we capture the reality of the women on board debates at different points of time and in different actor and motivational contexts. The study has consequences for how policy-makers and businesses may follow up and act, based on the debates. (shrink)
