In 2007. Terence Tao wrote on his blog an essay about soft analysis, hard analysis and the finitization of soft analysis statements into hard analysis statements. One of his main examples was a quasi-finitization of the infinite pigeonhole principle IPP, arriving at the "finitary" infinite pigeonhole principle FIPP₁. That turned out to not be the proper formulation and so we proposed an alternative version FIPP₂. Tao himself formulated yet another version FIPP₃ in a revised version of his essay. We give (...) a counterexample to FIPP₁ and discuss for both of the versions FIPP₂ and FIPP₃ the faithfulness of their respective finitization of IPP by studying the equivalences IPP ↔ FIPP₂ and IPP ↔ FIPP₃ in the context of reverse mathematics ([9]). In the process of doing this we also introduce a continuous uniform boundedness principle CUB as a formalization of Tao's notion of a correspondence principle and study the strength of this principle and various restrictions thereof in terms of reverse mathematics, i.e., in terms of the "big five" subsystems of second order arithmetic.

Information communication technology is spreading fast and wide. Driven by convenience, it enables people to undertake personal tasks and make decisions more easily and efficiently. Convenience enjoys an air of liberation as well as self-expression affecting all areas of life. The industry for children's toys is a major economic market becoming ever more tech-related and drawn into the battle for convenience. Like any other tech-related industry, this battle is about industry dominance and, currently, that involves networked toys. Networked toys aim (...) to enhance convenience for children and parents alike. Increasingly difficult to resist, these convenient networked devices are also a societal game changer. Neatly nestled in a lacuna juris and surrounded by a lack of clinical evidence, networked toys raise complex ethical issues concerning human development. This article lays bare the regulatory nexus for networked toys and invites ethical thinking to fill the gap to ensure sufficient protection for all human developmental stages. Networked toys not only affect but also might interfere with child development. Therefore, the article initially summarises the four key psychological stages through which the neurological development of the human brain processes. Each of these stages involves vital windows for human development in cognitive, emotional and social dimensions. Missing any of these developmental windows changes an individual human for life. The article then takes a look at the two main legal frameworks protecting the stages of human development which are applicable to networked toys: First, the examination of the human rights framework with its major segments emanating from the fundamental rights to privacy for family and home, to a child's education as well as to personal data reveals the use of current networked toys as a shielded part of parenting which tends to be at odds with privacy and data protection requirements. Second, the product liability framework for toy manufacturers requires evidence-based causality for putting a child's safety at risk. Unfortunately, these legal frameworks fail to offer sufficient protection of the human developmental stages. There is a lacuna juris. Although networked toys involve the risk of negatively impacting human development in every dimension, clinical psychological studies are impossible to acquire as court evidence for product liability because they take too long to provide reliable data while exposing several generations of children to the examined risk in the process. Meanwhile the temptation of convenience continues to drive the industry and consumers of networked toys and devices, which are already impacting children of all age groups. Accepting this phenomenon as an element of cognitive dissonance in society and in science falls far short of an appropriate ethical balance. The need for creating such an ethical balance concerning networked toys is all the more imperative because even if the networked toy industry managed to eliminate all psychological risks for human development and every legal conflict with privacy and security, significant ethical and societal risks of networked toys remain due to inevitable technological bias. Against these mounting changes, it is suggested that only an ethical approach of interdisciplinary research and learning seems most promising to develop an appropriate equilibrium between the complex challenges posed by networked toys and the societal values at stake.

The origin of eukaryotes is one of the major challenges of evolutionary cell biology. Other than the endosymbiotic origin of mitochondria and chloroplasts, the steps leading to eukaryotic endomembranes and endoskeleton are poorly understood. Ras‐family small GTPases are key regulators of cytoskeleton dynamics, vesicular trafficking and nuclear function. They are specific for eukaryotes and their expansion probably traces the evolution of core eukaryote features. The phylogeny of small GTPases suggests that the first endomembranes to evolve during eukaryote evolution had secretory, (...) and not phagocytic, function. Based on the reconstruction of putative roles for ancestral small GTPases, a hypothetical scenario on the origins of the first endomembranes, the nucleus, and phagocytosis is presented.

Los recientes acontecimientos económicos y su trascendental repercusión a nivel mundial, tienen entre alguna de sus más notables consecuencias la caída generalizada en los niveles de consumo. Paralelamente otro de los fenómenos cuasi-globales, el consumo masivo de objetos, se caracteriza cada vez más por la frugalidad de dichos objetos de consumo y la necesidad de sustituirlos por otros que aporten alguna novedad; lo que implica que el consumidor no pueda descansar en sus ansias consumistas. A partir de la unión de (...) estos dos aspectos, crisis económica y consumo posmoderno, se plantea un análisis social de algunos de los aspectos que caracterizan a la sociedad de consumo española en el momento presente y su repercusión en la distribución del gasto.

Ulrich Beck's best selling Risk Society established risk on the sociological agenda. It brought together a wide range of issues centering on environmental, health and personal risk, provided a rallying ground for researchers and activists in a variety of social movements and acted as a reference point for state and local policies in risk management. The Risk Society and Beyond charts the progress of Beck's ideas and traces their evolution. It demonstrates why the issues raised by Beck reverberate widely (...) throughout social theory and covers the new risks that Beck did not foresee, associated with the emergence of new technologies, genetic and cybernetic. The book is unique because it offers both an introduction to the main arguments in Risk Society and develops a range of critical discussions of aspects of this and other works of Beck. (shrink)

The cilium/flagellum is a sensory-motile organelle ancestrally present in eukaryotic cells. For assembly cilia universally rely on intraflagellar transport (IFT), a specialised bidirectional transport process mediated by the ancestral and conserved IFT complex. Based on the homology of IFT complex proteins to components of coat protein I (COPI) and clathrin-coated vesicles, we propose that the non- vesicular, membrane-bound IFT evolved as a specialised form of coated vesicle transport from a protocoatomer complex. IFT thus shares common ancestry with all protocoatomer derivatives, (...) including all vesicle coats and the nuclear pore complex (NPC). This has major implications for the evolutionary origin of the cilium. First, it reinforces the tenet that duplication and divergence of pre-existing structures, rather than symbiosis, were the major themes during cilium evolution. Second, it suggests that the initial step in the autogenous origin of the cilium was the establishment of a membrane patch with transmembrane proteins transported by the ancestral vesicle-coating IFT complex. We propose a scenario for how the initial membrane patch gradually protruded to enhance exposure to the environment, then started to move, and finally compartmentalised to render receptor signalling and ciliary beating more efficient.

We examined how the cultural dimension of universalism–particularism influences managers’ attitudes toward relational favoritism. Paradoxically, we found in a survey study that Brazilian and Chinese managers perceived more negative consequences of relational favoritism than did American managers—even though the Brazilians and the Chinese perceived stronger particularistic cultural norms in their countries than Americans did in the United States. We attribute this pattern of results to “cultural reflexivity”—the ability of people from transforming economies to be culturally self-critical during a period of (...) dramatic societal change. This pattern of results also emerged in a scenario study in which we asked these same Brazilian, Chinese, and American participants to assess managerial succession decisions made by a General Manager. We varied the scenarios so that the promoted manager was either a colleague with no pre-existing relation with the GM or a colleague who was a relative, a close friend, from the same town, or from the same school. Consistent with the results of the survey study, we found that perceived cultural norms of particularism were negatively related to perceptions of fairness. In other words, Brazilians and Chinese, even while living in more particularistic cultures, were more harsh in judging relational favoritism. We conclude with a discussion on the implications of these paradoxical relationships. (shrink)

ABSTRACT:U.S. Organizational Sentencing Guidelines provide firms with incentives to develop formal ethics programs to promote ethical organizational cultures and thereby decrease corporate offenses. Yet critics argue such programs are cosmetic. Here we studied bank employees before and after the introduction of formal ethics training—an important component of formal ethics programs—to examine the effects of training on ethical organizational culture. Two years after a single training session, we find sustained, positive effects on indicators of an ethical organizational culture (observed unethical behavior, (...) intentions to behave ethically, perceptions of organizational efficacy in managing ethics, and the firm’s normative structure). While espoused organizational values also rose in importance post-training, the boost dissipated after the second year which suggests perceptions of values are not driving sustained behavioral improvements. This finding conflicts with past theory which asserts that enduring behavioral improvements arise from the inculcation of organizational values. Implications for future research are discussed.

Con un'impostazione che coniuga la fedeltà testuale e l'approfondimento critico, il percorso di questo libro mira a ricondurre l'edificazione kierkegaardina - spesso considerata mera esortazione spirituale - allo spessore autenticamente filosofico d'una via soggettiva alla verità. Un modello antioggettivistico di filosofare senza perdere di vista né l'esercizio del dubbio né la dimensione della fede. Attraverso l' interpretazione kierkegaardiane di C. Fabro si è giunti all'esposizione e ai lineamenti descrittivi fondamentali della nozione del singolo. Il singolo viene presentato dallo stesso Kierkegaard (...) come la mia categoria. Sta di fatto che si può intendere l'intera produzione kierkegaardiana come un pensare soggettivamente il singolo. Pensiero etico carico di conseguenze pratiche, giacchè il danese non pretendeva fondare una scuola filosofica ma soltanto rendere attenti, svegliare le coscienze. (shrink)

At the beginning of the 21st century the conditio humana cannot be understood nationally or locally but only globally. This constitutes a revolution in the social sciences. The `sociological imagination' so far has basically been a nation state imagination. The main problem is how to redefine the sociological frame of reference in the horizon of a cosmopolitan imagination. For the purpose of empirical research I distinguish between three concepts: interconnectedness, liquid modernity and cosmopolitization from within. The latter is a kind (...) of class analysis after class analysis, which takes on board globalization internalized. For the purposes of social analysis, therefore, it is necessary to distinguish systematically between the national manifestation on the one hand and cosmopolitan reality of `global flows', currents of information, symbols, money, risks, people, social inequalities, on the other. This internal involuntary and often unseen cosmopolitanization from below of the national sphere of experience is occurring, however, with the power of economic globalization. So what does inner `cosmopolitanization' mean? The key concepts and questions of a way of life, such as nourishment, production, identity, fear, memory, pleasure, fate, power and politics, can no longer be located and understood nationally, but only globally whether in the shape of globally shared collective futures, capital flows, impending ecological or economic catastrophes, global foodstuff chains, transnational power games, or the `Esperanto' of pop music. In this article I look at transformation in the understanding of space-time, of identity, of the production paradigms, as well as at the resulting consequences for key sociological concepts like class and power and, within this frame, point to certain dilemmas of cosmopolitanism.

How can one distinguish the concept of second modernity from the concept of postmodernity? Postmodernists are interested in deconstruction without reconstruction, second modernity is about deconstruction and reconstruction. Social sciences need to construct new concepts to understand the world dynamics at the beginning of the 21st century. Modernity has not vanished, we are not post it. Radical social change has always been part of modernity. What is new is that modernity has begun to modernize its own foundations. This is what (...) it means to say modernity has become reflexive. It has become directed at itself. This causes huge new problems both in reality and in theory. There has been a pluralization of the boundaries within and between societies, between society and nature, between Us and Other, between life and death. This pluralization also changes the inherent nature of boundaries. They become not so much boundaries as a variety of attempts to draw of boundaries. Border conflicts become transformed into conflicts over the drawing of boundaries. Where postmodernism simply celebrates this multiplication of boundaries, the theory of second modernity starts with the problem this new reality poses for individual and collective decisions, and with the problem that the continued existence of such decisions poses for theory. Institutions that are capable of such conscious boundary drawing are enabled in a way that those of the first modernity were not. But this process also generates qualitatively new kinds of trouble and crises. To investigate those troubles is to unveil the emergence of the second modernity. (shrink)

An original analysis of the parallels between the arrested moment in photography and in the traumatized psyche.

Berger, U., Total sets and objects in domain theory, Annals of Pure and Applied Logic 60 91-117. Total sets and objects generalizing total functions are introduced into the theory of effective domains of Scott and Ersov. Using these notions Kreisel's Density Theorem and the Theorem of Kreisel-Lacombe-Shoenfield are generalized. As an immediate consequence we obtain the well-known continuity of computable functions on the constructive reals as well as a domain-theoretic characterization of the Heriditarily Effective Operations.

This article opens with general and historical remarks on philosophy of science's problems with the concept of discovery. Then, drawing upon simple examples of Watson's and Crick's non-philosophical usage, I characterize phrases of the type "x discovers y" semantically. It will subsequently be shown how widespread philosophical discussion on discovery violates the semantic constraints of phrases of the type "x discovers y." Then I provide a philosophical reconstruction of "x discovers y" that is in keeping with the "folk" notion of (...) discovery. The philosophical ingredients of this approach are taken from a certain aspect of action theory and from epistemological reliabilism. The approach draws upon the concept of superior action and connects this concept to progressive research. In contrast to normal actions, superior actions are primarily explained by competencies. This perspective includes reminders of what some nineteenth-century philosopher-scientists had advocated as a competence-oriented view on scientific research. Finally, this approach is applied to the case of Watson's and Crick's discovery. (shrink)

The discourse on climate politics so far is an expert and elitist discourse in which peoples, societies, citizens, workers, voters and their interests, views and voices are very much neglected. So, in order to turn climate change politics from its head onto its feet you have to take sociology into account. There is an important background assumption which shares in the general ignorance concerning environmental issues and, paradoxically, this is in corporated in the specialism of environmental sociology itself — this (...) is the category of ‘the environment’. If ‘the environment’ only includes everything which is not human, not social, then the concept is sociologically empty. If the concept includes human action and society, then it is scientifically mistaken and politically suicidal. (shrink)
