Critically discussing the causal social ontologies presented by Dave Elder-Vass and John Searle, the article argues that these views implausibly identify the causal ontological source of human sociality in collectively known, recognized and accepted statuses, criteria, norms and the like. This is implausible, for it ignores human sociality as occurring in temporally and spatially dispersed on-going processes of human interaction of differently placed, often unequal, and thus epistemically differently equipped actors in division of labour. Human scientific concepts are best seen (...) as picking out (aspects of) such complex and heterogeneous processes, not what the participating actors allegedly collectively know, accept or recognize about them. The article observes that similar appeals to collective recognition are also common in Wittgensteinian literature that, however, have claimed to reject the causal ontological view. It is argued that the ultimate value in rejecting the causal ontological view, and the accompanying idea of collective recognition, resides in that we thereby avoid epistemically homogenizing and over-intellectualizing the diverse mass of dispersed, often unequal, but interacting actors.

We introduce a linear analogue of Läuchli's semantics for intuitionistic logic. In fact, our result is a strengthening of Läuchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on functorial polymorphism, consists of dinatural transformations which are equivariant with respect to all such actions. Such dinatural transformations are called uniform. To any sequent in Multiplicative Linear Logic (...) , we associate a vector space of“diadditive” uniform transformations. We then show that this space is generated by denotations of cut-free proofs of the sequent in the theory MLL + MIX. Thus we obtain a full completeness theorem in the sense of Abramsky and Jagadeesan, although our result differs from theirs in the use of dinatural transformations.As corollaries, we show that these dinatural transformations compose, and obtain a conservativity result: diadditive dinatural transformations which are uniform with respect to actions of the additive group of integers are also uniform with respect to the actions of arbitrary cocommutative Hopf algebras. Finally, we discuss several possible extensions of this work to noncommutative logic.It is well known that the intuitionistic version of Läuchli's semantics is a special case of the theory of logical relations, due to Plotkin and Statman. Thus, our work can also be viewed as a first step towards developing a theory of logical relations for linear logic and concurrency. (shrink)

Distributed Leadership (DL) is a feature of education in many jurisdictions. Similarly, in Ireland the principles of DL have been adopted as part of a quality framework to underpin a system that provides high quality student care, learning and teaching. This model necessitates an alignment of senior leaders (SLs) and middle leaders (MLs) whose actions are informed by the needs and priorities of their particular school. The traditional notion of the ML position as a management position is changing. The evolution (...) requires a reconceptualisation, a transformation of the role and how we support and develop it to ensure that MLs are an integral part of the leadership structure of the school. This pragmatic research explored the PD needs of MLs in Irish, Education and Training Board (ETB) post-primary schools. It involved a mixed-methods, exploratory sequential study. Stage one involved a set of five semi structured interviews with AP I post holders. These were used as an instrument to develop the online surveys. Stage two involved quantitative research. Online surveys were distributed to all ETB schools in the republic of Ireland. In stage three a summary of the findings of the survey were shared with ten AP Is who were subsequently interviewed to gain further insights. The study illustrated that the development of MLs requires the support of SLs, skills development, a supportive school culture and combined training for senior and middle leaders which should be facilitated by an independent person.

Traditionally Hume is seen as offering an ‘empiricist’ critique of ‘rationalism’. This view is often illustrated – or rejected – by comparing Hume's views with those of Descartes'. However the textual evidence shows that Hume's most sustained engagement with a canonical ‘rationalist’ is with Nicolas Malebranche. The author shows that the fundamental differences (among the many similarities) between the two on the self and causal power do indeed rest on a principled distinction between ‘rationalism’ and ‘empiricism’, and that there is (...) some truth in the traditional story. This, however, is very far from saying that Hume's general orientation is an attack on something called ‘rationalism’. (shrink)

Cartesian representationalism and the Enlightenment heritage more broadly continue to play a pivotal role in shaping the 21st-century human scientific theory and practice. This introduction to a special section on the topic surveys some aspects of that heritage.

pausanias Preserves what we know about the Little and the Great Daidala, religious celebrations which took place in Plataia from the classical into the Roman period. To his account can be added a fragment from Plutarch's work, and a brief mention in Menander Rhetor. At the celebration of the Little Daidala, which occurred about every six years or so, the Plataians made an image from the trunk of an oak tree ; they called the image a daidalon, because ‘the men (...) of old’ called the wooden images, the xoana, daidala. Every sixty years, the Plataians celebrated the Great Daidala, to which other Boiotian states sent representations. At this Great Daidala, all the images which had been made at the Little Daidala were gathered together and burnt. The process by which this was done was to allocate by lot to each of the important Boiotian towns one of the daidala, and to distribute the rest amongst the lesser Boiotian states, who would pool their resources so as to be able to participate in the ceremony. Each large city, or a group of smaller cities, was thus responsible for one daidalon. (shrink)

Christian Emden’s informative book has a number of explicit aims: the first aim is to “reconstruct Nietzsche’s philosophical naturalism”; the second aim is to show “that there are specific historical reasons why Nietzsche came to adopt a position best understood in terms of philosophical naturalism”; and the third aim is to show “how Nietzsche’s naturalism and his understanding of the life sciences tie in with genealogy.”1 In pursuit of these aims, Emden divides the book into three parts, one titled “Varieties (...) of Philosophical Naturalism,” the second “Evolution and the Limits of Teleology,” and the third “Genealogy, Nature and Normativity.” In this article I shall concentrate mainly on Emden’s discussion of...

Rapid advances in the domain of science and technology are having an unprecedented effect upon the provision of higher education in universities throughout the world, the pace of change often being so fast as to make planning for the development of the “classroom of the future” an extremely difficult task. The Mobile Multimedia University (MMU) project, a collaborative action between four leading UK based research facilities, has been established to investigate these issues. Included amongst its aims is the use of (...) novel research methodologies to determine the factors which will influence the shape and form of future education provision, and thus the distribution of knowledge to society, such as mobility, telecommunications and multimedia services. This paper describes the use of a Delphi survey in predicting the technological trends and innovations which will affect university education in the near future. It describes the theory underpinning the Delphi method, illustrating this with examples of how such a technique has been successfully used in the past. It then details the specific application of the Delphi approach within the current MMU research project, detailing the preliminary results and discussing the implications of these findings for the future of universities and other institutes of higher education.

The growth factor progranulin (PGRN) regulates cell division, survival, and migration. PGRN is an extracellular glycoprotein bearing multiple copies of the cysteine‐rich granulin motif. With PGRN family members in plants and slime mold, it represents one of the most ancient of the extracellular regulatory proteins still extant in modern animals. PRGN has multiple biological roles. It contributes to the regulation of early embryogenesis, to adult tissue repair and inflammation. Elevated PGRN levels often occur in cancers, and PGRN immunotherapy inhibits the (...) growth of hepatic cancer xenografts in mice. Recent studies have demonstrated roles for PGRN in neurobiology. An autosomal dominant mutation in GRN, the gene for PGRN, leads to neuronal atrophy in the frontal and temporal lobes, resulting in the disease frontotemporal lobar dementia. In this review we will discuss current knowledge of the multifaceted biology of PGRN. (shrink)
