    Introduction to the Special Issue on Liminal Hotspots

    This article introduces a special issue of Theory and Psychology on liminal hotspots. A liminal hotspot is an occasion during which people feel they are caught suspended in the circumstances of a transition that has become permanent. The liminal experiences of ambiguity and uncertainty that are typically at play in transitional circumstances acquire an enduring quality that can be described as a “hotspot”. Liminal hotspots are characterized by dynamics of paradox, paralysis, and polarization, but they also intensify the potential for pattern shift. The origins of the concept are described followed by an overview of the contributions to this special issue

    Non-foundational criticality? On the need for a process ontology of the psychosocial

    Get PDF
    The articulation of critical dialects of psychology has typically involved a questioning of the foundational assumptions of the so-called mainstream. This has included critiques in the name of more adequate scientific foundations, but more recently these have been accompanied by critiques in the name of an absence of foundations altogether, and critiques that suggest a rethinking of the concept of foundation. These latter versions are usually influenced by the great 20th Century non-foundational philosophies of figures such as Bergson, Whitehead, Wittgenstein and Heidegger, or by related thinkers such as Deleuze, Serres, Luhmann, Butler and Stengers. In foregrounding themes of process and multiplicity such thinkers provide potent tools for critically rethinking psychological questions. Less positive has been a tendency amongst critical psychologists to polarise natural and social scientific issues and to associate the former with negative images (all that is static, mechanistic, essentialist and conservative). This can lead to a formulaic criticality in which arguments for nature are bad, and those for culture are good. Deconstruction comes to appear simply as an assertion of ‘the discursive construction of’ whatever phenomenon is under scrutiny. To counteract this trend, the proposed paper will discuss a process approach to ontology that welcomes contributions from the natural sciences as well as the humanities and social sciences

    On standards and values: Between finite actuality and infinite possibility

    Get PDF
    This article explores the relation between subjects and standards in a way that is informed by a process orientation to theoretical psychology. Standards are presented as objectifications of values designed to generalize and stabilize experiences of value. Standards are nevertheless prone to becoming “parodic” in the sense that they can become obstacles to the actualization of the values they were designed to incarnate. Furthermore, much critical social science has mishandled the nature of standards by insisting that values are nothing but local and specific constructions in the mundane world of human activity. To rectify this problem, this article reactivates a sense of the difference between the idea of a finite world of activity and a world of value which points beyond and exceeds passing circumstance. Resources for the reactivation of this difference— which is core to a processual grasp of self, memory, and value—are found in the thinking of A. N. Whitehead, Max Weber, Marcel Proust, and Soren Kierkegaard

    Adattamenti biochimici alla speleologia alpina

    La speleologia ù un esercizio fisico di tipo aerobico anaerobico alternato di lunghissima durata (10-30 ore) con carico motorio molto intenso e vario. Questa attività richiede un’elevata conoscenza degli schemi motori posturali e dinamici, adattabilità delle capacità senso-percettive all’ambiente, sviluppo delle capacità coordinative speciali e condizionali. Scopo della ricerca: indagare quali fossero gli eventuali adattamenti biochimici indotti da questa attività.Caving is a form of physical excise, alternating between aerobic and anaerobic, with a very long duration (10-30 hours) and an extremely intense and varied motor load. The activity requires an in-depth knowledge of postural and dynamic motor patterns, sensory-perceptual skills that can easily adapt to the environment and highly developed specialized and conditional coordination skills. Aim of the study: explore the possible biochemical adaptations induced by this activity

    Language Modeling by Clustering with Word Embeddings for Text Readability Assessment

    We present a clustering-based language model using word embeddings for text readability prediction. Presumably, an Euclidean semantic space hypothesis holds true for word embeddings whose training is done by observing word co-occurrences. We argue that clustering with word embeddings in the metric space should yield feature representations in a higher semantic space appropriate for text regression. Also, by representing features in terms of histograms, our approach can naturally address documents of varying lengths. An empirical evaluation using the Common Core Standards corpus reveals that the features formed on our clustering-based language model significantly improve the previously known results for the same corpus in readability prediction. We also evaluate the task of sentence matching based on semantic relatedness using the Wiki-SimpleWiki corpus and find that our features lead to superior matching performance

    Energy transport faster than light in good conductors and superconductors

    People need a model to study tachyons whose prediction can be tested easily. The dispersion relation w^2=k^2C^2-a^2C^2 of a low-frequency electromagnetic field in good conductors is equivalent to the energy-momentum equation E^2=p^2C^2-m^2C^4 of a tachyon where the proportionality coefficient is h^2. An experiment in 1980s to measure the phase velocity Vp [1] can be regarded as an indirect evidence of the superluminal velocity V>>c of those photons just equals the rate of energy flow S/w of the field.Instability of the tachyonic field corresponds to the Joule heat. To detect the speed of energy is difficult and we plan to modulate signals to observe the information velocity (speed of points of non-analyticity)[2].Comment: 16 page
