Exponential Convergence Towards Stationary States for the 1D Porous Medium Equation with Fractional Pressure

We analyse the asymptotic behaviour of solutions to the one dimensional fractional version of the porous medium equation introduced by Caffarelli and V\'azquez, where the pressure is obtained as a Riesz potential associated to the density. We take advantage of the displacement convexity of the Riesz potential in one dimension to show a functional inequality involving the entropy, entropy dissipation, and the Euclidean transport distance. An argument by approximation shows that this functional inequality is enough to deduce the exponential convergence of solutions in self-similar variables to the unique steady states

Husserls "Allgemeine Erkenntnistheorie" von 1902/03. Zur Frühentwicklung der phänomenologischen Methode

The first explicit account of the phenomenological method has a crucial historical significance not just for the development of the method itself, but also for the history of phenomenology in general. In his lecture General Theory of Knowledge (Allgemeine Erkenntnistheorie) of 1902/03, the early Husserl develops the two major operational concepts of the phenomenological method, namely the Epoché and the phänomenologische Reduktion, in a systematic relation in order to achieve an adequate investigation of the transcendental consciousness. This paper discusses in detail the theoretical and historical content of this underexplored early lecture in a developmental perspective for the history of philosophy

The Incipient Mind Argument: The Persistence of Absolutist Thinking in Biological Philosophy of Mind

The incipient mind argument is the central argument of Evan Thompson’s solution to the so-called mind-body problem. This paper challenges Evan Thompson’s (and Francisco Varela’s) assumption of a pristine form of subjectivity, as well as of interiority in unicellular life forms. I claim that this assumption makes sense only as a useful strategy for an absolutist account of mind. In this paper, I argue that Thompson’s thesis is erroneous at the object-level, as well as at the meta-level of his argumentation. By paying greater attention to the meta-level of his exposition, I show that Thompson’s assumption of an “incipient mind” obeys an absolutist, two-sided pattern of thinking and, therefore, that his argumentation fails to give an accurate account of the systemic generation and development of mind. After demonstrating this, I suggest an innovative action-based approach to mind in order to accurately give an account of its real-constructive development

Die vorbegriffliche reduktive Massnahme in Husserls früher Göttinger Zeit. Zur Entstehung des Reduktionsbegriffes

Within the scope of a comprehensive investigation about the historical development of the term "reduction", this paper specially takes the genesis of that development into consideration. The present study analyses and explicates the pre-conceptual use of the phenomenological reduction according to the early manuscript fragment F I 6/129, referring to the Seefelder Manuskripte as well as to the five lectures Die Idee der Phänomenologie. This analysis challenges the traditional date given for the first use of "reduction" as a phenomenological method by understanding the motivation behind its genesis more precisely and outlining the focus on the historical development from the first methodological approach to the concept of reduction within Husserl's early epistemological phenomenology

Counterfactual Truths: The Logical Structure of Argumentative Thought Experiments

Argumentative thought experiments are structurally conditional clauses. They can hence be formalized by means of the principle of modus ponendo ponens, as well as of modus tollendo tollens. In contrast to the practice in formal logic, exponents of argumentative thought experiments claim that the logical validity of a conclusion drawn within the framework of a particular conditional argument also holds beyond the particular conditional in question. In this paper, I articulate the criticism that this claim is wrong by arguing that the counterfactual scenario sets itself the most determinant premise. If the counterfactual scenario sets the initial conditional premise of the argument, then its true conclusion holds only as a counterfactual truth. The present paper illustrates this criticism using Frank Jackson’s thought experiment, the so-called knowledge argument, as a concrete example

Influence of serological factors and BMI on the blood pressure/hematocrit association in healthy young men and women.

The association between mean arterial blood pressure (MAP) and hematocrit (Hct) as a surrogate for blood viscosity was investigated in a young (average 20.0±2.3 years), healthy population of 174 men and 442 women. Health status was assessed by clinical examination and serological evaluation. Individuals with severe anemia or hemoconcentration, prior traumas or major surgical intervention, smokers, and pregnant or lactating women were excluded from the study. The MAP/Hct association was positive and significant (P=0.04) for women and negative, albeit not significantly so, for men. The MAP/Hct association was also evaluated in subgroups of the same population with a progressive step-by-step exclusion of: individuals with cholesterol >200 mg/dL; triglycerides >200 mg/dL; body mass index >25 kg/m(2); and glucose >100 mg/dL. This consecutively reduced the strength of the positive MAP/Hct association in women, which became negative - although not significantly so - when all anomalously high factors were excluded. The same trend was found in men. Our study indicates that previously reported positive trends in the relationship between the MAP and Hct in the population are not present in a young, healthy population of men or women that excludes individuals with the confounding factors of above normal serological values and BMI

Avoiding Pandemic Fears in the Subway and Conquering the Platypus.

Metagenomics is increasingly used not just to show patterns of microbial diversity but also as a culture-independent method to detect individual organisms of intense clinical, epidemiological, conservation, forensic, or regulatory interest. A widely reported metagenomic study of the New York subway suggested that the pathogens Yersinia pestis and Bacillus anthracis were part of the "normal subway microbiome." In their article in mSystems, Hsu and collaborators (mSystems 1(3):e00018-16, 2016, http://dx.doi.org/10.1128/mSystems.00018-16) showed that microbial communities on transit surfaces in the Boston subway system are maintained from a metapopulation of human skin commensals and environmental generalists and that reanalysis of the New York subway data with appropriate methods did not detect the pathogens. We note that commonly used software pipelines can produce results that lack prima facie validity (e.g., reporting widespread distribution of notorious endemic species such as the platypus or the presence of pathogens) but that appropriate use of inclusion and exclusion sets can avoid this issue

Animated Machines, Organic Souls: Maturana and Aristotle on the Nature of Life

The emergence of mind is a central issue in cognitive philosophy. The main working assumption of the present paper is that several important insights in answering this question might be provided by the nature of life itself. It is in this line of thinking that this paper compares two major philosophical conceptualizations of the living in the history of theoretical biology, namely those of Maturana and Aristotle. The present paper shows how both thinkers describe the most fundamental properties of the living as autonomous sustenance. The paper also shows how these theoretical insights might have a consequence upon our understanding of a specific constructiveness of human cognition, here referred to as enarrativity, if this can be considered in a structural as well as evolutionary connection with the structure of life as such. The paper finally suggests that the structural connection made here can be traced from the fundamental organization of self-preservation to survival behaviors to constructive orientation and action

German Freemasonry and Framed Cognitive Immersion: The Transcultural Power of the Masonic Master Ritual

This paper identifies theories and cognitive aspects that shed light on the transcultural unifying identity power of Masonic initiation rituals and illustrates this more closely using the case study of the German master ritual. It suggests that the potential of the unifying identity of Masonic rituals does not reside solely in their symbolism, but rather primarily in their enactment as performance. By breaking down the basic elements of the performative character of rituals and comparing the Masonic ritual to that of male initiation among the Chambri people of Papua New Guinea within Whitehouse’s theoretical model of modes of religiosity, this paper also explores the transcultural unifying identity power of rituals while outlining a novel explanatory framework in the field of Cognitive Science of Religion (CSR) and Ritual Studies. The present paper suggests that religious and religiously connoted transcultural unifying identity, including its inherent capacity for meaning creation and meaning attribution, is more strongly and stably achieved the more Framed Cognitive Immersion (FCI) is engaged, that is, the more corresponding cognitive processes of the participants are triggered together.:1.

THE CONNECTION BETWEEN DOMESTIC VIOLENCE AND ANIMAL CRUELTY IN PUERTO RICO: AN ANTHROPOLOGICAL STUDY

Violence against women is one of Puerto Rico’s most critical social problems and for this reason, anthropological thought is critically necessary. Some women in Puerto Rico are vulnerable to situations of violence and control through domestic violence while their animals become involved in the same tangle of abuse. Women’s voices about their animals have not been heard simply because nobody has inquired. I asked women survivors of domestic abuse whether or not their male partners had engaged in any type of animal cruelty against household and domesticated animals. My intention in conducting this research was to examine, both from an anthropological and from a gender perspective, the correlation in Puerto Rico between domestic violence and animal cruelty through ethnographic work. Interviews with professional shelter staff were conducted as well to establish whether or not women seeking shelter talk about their pets being hurt by their male partners—and if so, what consequences that abuse has for the women. My main objective was to determine whether the results of research that had been conducted in other cultures that demonstrated a link between animal abuse and domestic violence findings would be translatable to Puerto Rican culture. There is a remarkable void in this area of study in the Caribbean and Latin America that needs to be addressed and this study is a contribution toward analysis, dialogue, and change
