ENERGY, ENTROPY, and INFORMATION Jean Thoma June
ENERGY, ENTROPY, AND INFORMATION Jean Thoma June 1977 Research Memoranda are interim reports on research being conducted by the International Institute for Applied Systems Analysis, and as such receive only limited scientific review. Views or opinions contained herein do not necessarily represent those of the Institute or of the National Member Organizations supporting the Institute. PREFACE This Research Memorandum contains the work done during the stay of Professor Dr.Sc. Jean Thoma, Zug, Switzerland, at IIASA in November 1976. It is based on extensive discussions with Professor HAfele and other members of the Energy Program. Al- though the content of this report is not yet very uniform because of the different starting points on the subject under consideration, its publication is considered a necessary step in fostering the related discussion at IIASA evolving around th.e problem of energy demand. ABSTRACT Thermodynamical considerations of energy and entropy are being pursued in order to arrive at a general starting point for relating entropy, negentropy, and information. Thus one hopes to ultimately arrive at a common denominator for quanti- ties of a more general nature, including economic parameters. The report closes with the description of various heating appli- cation.~and related efficiencies. Such considerations are important in order to understand in greater depth the nature and composition of energy demand. This may be highlighted by the observation that it is, of course, not the energy that is consumed or demanded for but the informa- tion that goes along with it.

Global Participatory Acts and the State
STRENGTHENING THE STATE THROUGH DISSENT: GLOBAL PARTICIPATORY ACTS AND THE STATE By Patricia Camilien, université Quisqueya INTRODUCTION In Alvin Toffler‟s Future Shock (1970), three types of men coexist on the planet. Men of the present, living in the here and now as they are carried away by the waves and currents of the world; they are rather vulnerable to "future shock". Men of the past, who have remained in a past time long gone, are living in the twentieth century but are still in the twelfth. Men of the future, informed, insightful and perceptive, who are already surfing on the major trends of tomorrow. In today's world, these men of the future are part of a transnational and nomadic elite helped by the increasing liberalization of trade and the disappearance of borders – at the least for them. Transnational companies like oil brokerage firm Trafigura i – made globally (in) famous in 2010 by a journalist‟s tweet about a file hosted on WikiLeaks – exemplify this (future) global world. They enjoy the best of corporate law around the world and diversify their operations accordingly. This use of different national laws according to the benefits they offer is not limited to transnational corporations and their owners, but now extends to individuals who, while they are not billionaires in dollars, are so in reticular connections. Using global participatory acts (heretofore participactions), they seem to be the ones to help the people move from the present to the future. Moral and social entrepreneurs, they are the vanguard of the future changes in society they are trying to drive through networked actions as relayed by mass self- communication. -
Entropy and Life
Entropy and life Research concerning the relationship between the thermodynamics textbook, states, after speaking about thermodynamic quantity entropy and the evolution of the laws of the physical world, that “there are none that life began around the turn of the 20th century. In 1910, are established on a firmer basis than the two general American historian Henry Adams printed and distributed propositions of Joule and Carnot; which constitute the to university libraries and history professors the small vol- fundamental laws of our subject.” McCulloch then goes ume A Letter to American Teachers of History proposing on to show that these two laws may be combined in a sin- a theory of history based on the second law of thermo- gle expression as follows: dynamics and on the principle of entropy.[1][2] The 1944 book What is Life? by Nobel-laureate physicist Erwin Schrödinger stimulated research in the field. In his book, Z dQ Schrödinger originally stated that life feeds on negative S = entropy, or negentropy as it is sometimes called, but in a τ later edition corrected himself in response to complaints and stated the true source is free energy. More recent where work has restricted the discussion to Gibbs free energy because biological processes on Earth normally occur at S = entropy a constant temperature and pressure, such as in the atmo- dQ = a differential amount of heat sphere or at the bottom of an ocean, but not across both passed into a thermodynamic sys- over short periods of time for individual organisms. tem τ = absolute temperature 1 Origin McCulloch then declares that the applications of these two laws, i.e. -
Minding the Body Interacting Socially Through Embodied Action
Linköping Studies in Science and Technology Dissertation No. 1112 Minding the Body Interacting socially through embodied action by Jessica Lindblom Department of Computer and Information Science Linköpings universitet SE-581 83 Linköping, Sweden Linköping 2007 © Jessica Lindblom 2007 Cover designed by Christine Olsson ISBN 978-91-85831-48-7 ISSN 0345-7524 Printed by UniTryck, Linköping 2007 Abstract This dissertation clarifies the role and relevance of the body in social interaction and cognition from an embodied cognitive science perspective. Theories of embodied cognition have during the past two decades offered a radical shift in explanations of the human mind, from traditional computationalism which considers cognition in terms of internal symbolic representations and computational processes, to emphasizing the way cognition is shaped by the body and its sensorimotor interaction with the surrounding social and material world. This thesis develops a framework for the embodied nature of social interaction and cognition, which is based on an interdisciplinary approach that ranges historically in time and across different disciplines. It includes work in cognitive science, artificial intelligence, phenomenology, ethology, developmental psychology, neuroscience, social psychology, linguistics, communication, and gesture studies. The theoretical framework presents a thorough and integrated understanding that supports and explains the embodied nature of social interaction and cognition. It is argued that embodiment is the part and parcel of social interaction and cognition in the most general and specific ways, in which dynamically embodied actions themselves have meaning and agency. The framework is illustrated by empirical work that provides some detailed observational fieldwork on embodied actions captured in three different episodes of spontaneous social interaction in situ. -
Markets Not Capitalism Explores the Gap Between Radically Freed Markets and the Capitalist-Controlled Markets That Prevail Today
individualist anarchism against bosses, inequality, corporate power, and structural poverty Edited by Gary Chartier & Charles W. Johnson Individualist anarchists believe in mutual exchange, not economic privilege. They believe in freed markets, not capitalism. They defend a distinctive response to the challenges of ending global capitalism and achieving social justice: eliminate the political privileges that prop up capitalists. Massive concentrations of wealth, rigid economic hierarchies, and unsustainable modes of production are not the results of the market form, but of markets deformed and rigged by a network of state-secured controls and privileges to the business class. Markets Not Capitalism explores the gap between radically freed markets and the capitalist-controlled markets that prevail today. It explains how liberating market exchange from state capitalist privilege can abolish structural poverty, help working people take control over the conditions of their labor, and redistribute wealth and social power. Featuring discussions of socialism, capitalism, markets, ownership, labor struggle, grassroots privatization, intellectual property, health care, racism, sexism, and environmental issues, this unique collection brings together classic essays by Cleyre, and such contemporary innovators as Kevin Carson and Roderick Long. It introduces an eye-opening approach to radical social thought, rooted equally in libertarian socialism and market anarchism. “We on the left need a good shake to get us thinking, and these arguments for market anarchism do the job in lively and thoughtful fashion.” – Alexander Cockburn, editor and publisher, Counterpunch “Anarchy is not chaos; nor is it violence. This rich and provocative gathering of essays by anarchists past and present imagines society unburdened by state, markets un-warped by capitalism. -

The World Economic Forum listed massive digital misin- formation as one of the main threats for our society. The spreading of unsubstantiated rumors may have serious consequences on public opin- ion such as in the case of rumors about Ebola causing disruption to health-care workers. In this work we target Facebook to characterize information consumption patterns of 1.2 M Italian users with respect to verified (science news) and unverified (conspiracy news) contents. Through a thorough quantitative analysis we provide important in- sights about the anatomy of the system across which misinformation might spread. In particular, we show that users’ engagement on veri- fied (or unverified) content correlates with the number of friends hav- ing similar consumption patterns (homophily). Finally, we measure how this social system responded to the injection of 4, 709 false information. We find that the frequent (and selective) exposure to specific kind of content (polarization) is a good proxy for the detection of homophile clusters where certain kind of rumors are more likely to spread. -

Myrmecological News 20 25-36 Online Earlier, for print 2014 The evolution and functional morphology of trap-jaw ants (Hymenoptera: Formicidae) Fredrick J. LARABEE & Andrew V. SUAREZ Abstract We review the biology of trap-jaw ants whose highly specialized mandibles generate extreme speeds and forces for predation and defense. Trap-jaw ants are characterized by elongated, power-amplified mandibles and use a combination of latches and springs to generate some of the fastest animal movements ever recorded. Remarkably, trap jaws have evolved at least four times in three subfamilies of ants. In this review, we discuss what is currently known about the evolution, morphology, kinematics, and behavior of trap-jaw ants, with special attention to the similarities and key dif- ferences among the independent lineages. We also highlight gaps in our knowledge and provide suggestions for future research on this notable group of ants.

Semantic Homophily in Online Communication: Evidence from Twitter
A Semantic homophily in online communication: evidence from Twitter SANjA Sˇ CEPANOVI´ C´ , Aalto University IGOR MISHKOVSKI, University Ss. Cyril and Methodius BRUNO GONC¸ALVES, New York University NGUYEN TRUNG HIEU, University of Tampere PAN HUI, Hong Kong University of Science and Technology People are observed to assortatively connect on a set of traits. This phenomenon, termed assortative mixing or sometimes homophily, can be quantified through assortativity coefficient in social networks. Uncovering the exact causes of strong assortative mixing found in social networks has been a research challenge. Among the main suggested causes from sociology are the tendency of similar individuals to connect (often itself referred as homophily) and the social influence among already connected individuals. Distinguishing between these tendencies and other plausible causes and quantifying their contribution to the amount of assortative mixing has been a difficult task, and proven not even possible from observational data. However, another task of similar importance to researchers and in practice can be tackled, as we present here: understanding the exact mechanisms of interplay between these tendencies and the underlying social network structure. Namely, in addition to the mentioned assortativity coefficient, there are several other static and temporal network properties and substructures that can be linked to the tendencies of homophily and social influence in the social network and we herein investigate those. Concretely, we tackle a computer-mediated communication network (based on Twitter mentions) and a particular type of assortative mixing that can be inferred from the semantic features of communication content that we term semantic homophily. Our work, to the best of our knowledge, is the first to offer an in-depth analysis on semantic homophily in a communication network and the interplay between them. -

Keywords: We investigated the relevance of visual cues (canopy, horizon patterns) during navigation in O. hastatus. Arboreal ants Laboratory experiments using a captive ant colony and a round foraging arena revealed that an artificial Atlantic forest canopy pattern above the ants and horizon visual marks are effective orientation cues for homing O. has- Canopy orientation tatus. On the other hand, foragers that were only given a tridimensional landmark (cylinder) or chemical Ponerinae marks were unable to home correctly. Navigation by visual cues in O. hastatus is in accordance with other Trap-jaw ants diurnal arboreal ants. Nocturnal luminosity (moon, stars) is apparently sufficient to produce contrasting Visual cues silhouettes from the canopy and surrounding vegetation, thus providing orientation cues. -
Politics of Care
THE POLITICS OF CARE' Laura T. Kessler INTRODUCTION Can family caregiving be a form of political resistance or expression? It can, especially when done by people ordinarily denied the privilege of family privacy by the state. Feminist and queer theorists within law have, for the most part, over- looked this aspect of caregiving, regarding unpaid family labor as a source of gender-based oppression or as an undervalued public commodity. Conse- quently, prominent feminist and queer legal theorists have set their sights on wage work1 or sexual liberation2 as more promising sources of emancipation for women. Although other legal feminists continue to focus on the problem of devalued family labor, these theorists tend to justify increased support for care work primarily on the benefits it confers on children and society, on liberal theories of societal obligation, on ending gender oppression, or on simple hu- man needs.3 This article examines a less well-explored conception of family caregiving within the feminist and queer legal theory literature, revealing the way that family caregiving can be a liberating practice for caregivers qua caregivers. Specifically, care work can constitute an affirmative political practice of resis- tance to a host of discriminatory institutions and ideologies, including the fam- ily, workplace, and state, as well as patriarchy, racism, and homophobia.
