The savanna theory of happiness proposes that, due to evolutionary constraints on the human brain, situations and circumstances that would have increased our ancestors’ happiness may still increase our happiness today, and those that would have decreased their happiness then may still decrease ours today. It further proposes that, because general intelligence evolved to solve evolutionarily novel problems, this tendency may be stronger among less intelligent individuals. Because humans are a diurnal species that cannot see in the dark, darkness always (...) represented danger to our ancestors and may still decrease our happiness today. Consistent with this prediction, the analysis of the National Longitudinal Study of Adolescent to Adult Health (Add Health) data shows that exposure to sunlight was associated with happiness but the association was significantly weaker among more intelligent individuals.

This paper analyses the gender pay determinants between top and lower level of Portuguese employees. A relatively large data pool, for 2003, covering business functions hitherto neglected, sheds a new light into the factors that lead to the earnings of men and women. Our analysis combines human capital with internal-labour-markets theories. Our findings allow the identification of jobsegregation as one important source of the gender pay gap. Moreover, they confirm that earnings are determined by different factors and suggest a reasonable (...) opportunity for women to combine career and family. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

In this paper we analyze some aspects of the question of using methods from model theory to study structures of functional analysis.By a well known result of P. Lindström, one cannot extend the expressive power of first order logic and yet preserve its most outstanding model theoretic characteristics (e.g., compactness and the Löwenheim-Skolem theorem). However, one may consider extending the scope of first order in a different sense, specifically, by expanding the class of structures that are regarded as models (e.g., (...) including Banach algebras or other structures of functional analysis), and ask whether the resulting extensions of first order model theory preserve some of its desirable characteristics.A formal framework for the study of structures based on Banach spaces from the perspective of model theory was first introduced by C. W. Henson in [8] and [6]. Notions of syntax and semantics for these structures were defined, and it was shown that using them one obtains a model theoretic apparatus that satisfies many of the fundamental properties of first order model theory. For instance, one has compactness, Löwenheim-Skolem, and omitting types theorems. Further aspects of the theory, namely, the fundamentals of stability and forking, were first introduced in [10] and [9].The classes of mathematical structures formally encompassed by this framework are normed linear spaces, possibly expanded with additional structure,e.g., operations, real-valued relations, and constants. This notion subsumes wide classes of structures from functional analysis. However, the restriction that the universe of a structure be a normed space is not necessary. (This restriction has a historical, rather than technical origin; specifically, the development of the theory was originally motivated by questions in Banach space geometry.) Analogous techniques can be applied if the universe is a metric space. Now, when the underlying metric topology is discrete, the resulting model theory coincides with first order model theory, so this logic extends first order in the sense described above. Furthermore, without any cost in the mathematical complexity, one can also work in multi-sorted contexts, so, for instance, one sort could be an operator algebra while another is. say, a metric space.

A Text Worthy of Plotinus makes available for the first time information on the collaborative work that went into the completion of the first reliable edition of Plotinus’ Enneads: Plotini Opera, editio maior, three volumes (Brussels, Paris, and Leiden, 1951-1973), followed by the editio minor, three volumes (Oxford, 1964-1983). Pride of place is given to the correspondence of the editors, Paul Henry S.J. and Hans-Rudolf Schwyzer, with other prominent scholars of late antiquity, amongst whom are E.R. Dodds, B.S. Page, A.H. (...) Armstrong, and J. Igal S.J. Also included in the volume are related documents consisting in personal memoirs, course handouts and extensive biographical notices of the two editors as well as of those other scholars who contributed to fostering the revival of Plotinus in the latter half of the 20th century. Taken together, letters and documents let the reader into the problems – codicological, exegetical, and philosophical – that are involved in the interpretation of medieval manuscripts and their transcription for modern readers. Additional insights are provided into the nature of collaborative work involving scholars from different countries and traditions. A Text Worthy of Plotinus will prove a crucial archive for generations of scholars. Those interested in the philosophy of Plotinus will find it a fount of information on his style, manner of exposition, and handling of sources. The volume will also appeal to readers interested in broader trends in 20th century scholarship in the fields of Classics, History of Ideas, Theology, and Religion. (shrink)

En la Historia de la filosofía aparece Pedro Hispano Portugalense como filósofo, médico científico, político, papa. Pero, se trata de uno o de varios autores? El autor de este artículo estudia algunos aspectos relacionados con la vida, la obra y la personalidad de Pedro Hispano para distinguirlo de los personajes con los que ha sido confundido. El autor distingue entre Pedro Hispano O. P., Pedro Hispano Portugalense y Pedro Hispano médico, al que algunos confunden con Pedro Juliano, que fue papa, (...) con el nombre de Juan XXI.According to the History of philosophy, Petrus Hispanus Portugalensis was philosopher, physician, scientist, politician and pope. But how many persons are there really? One, several? The author of this article studies some aspects related with the life, writings and personality of Petrus Hispanus in order to distinghish him from the people he has been confounded with. The author concludes that there are three different persons: a) Petrus Hispanus, O.P., b) Petrus Hispanus Portugalensis, c) Petrus Hispanus, physician, whom some historians confound with Petrus Julianus, who became a pope with the name of John XXI.

We study connections between asymptotic structure in a Banach space and model theoretic properties of the space. We show that, in an asymptotic sense, a sequence $$ in a Banach space X generates copies of one of the classical sequence spaces $\ell_p$ or $c_0$ inside X if and only if the quantifier-free types approximated by $$ inside X are quantifier-free definable. More precisely, if $$ is a bounded sequence X such that no normalized sequence of blocks of $$ converges, then (...) the following two conditions are equivalent. There exists a sequence $$ of blocks of $$ such that for every finite dimensional subspace E of X, every quantifier-free type over $E +\overline{\rm span}\{y_n\mid n\in \mathbb{N}\}$ is quantifier-free definable. One of the following two conditions holds: there exists $1\le p 0$ and every finite dimensional subspace E of X there exists a sequence of blocks of $$ which is $$-equivalent over E to the standard unit basis of $\ell_p$; for every $\epsilon>0$ and every finite dimensional subspace E of X there exists a sequence of blocks of $$ which is $$-equivalent over E to the standard unit basis of $c_0$. Several byproducts of the proof are analyzed. (shrink)

Tarski's 1936 paper, “On the concept of logical consequence”, is a rather philosophical, non-technical paper that leaves room for conflicting interpretations. My purpose is to review some important issues that explicitly or implicitly constitute its themes. My discussion contains four sections: terminological and conceptual preliminaries, Tarski's definition of the concept of logical consequence, Tarski's discussion of omega-incomplete theories, and concluding remarks concerning the kind of conception that Tarski's definition was intended to explicate. The third section involves subsidiary issues, such as (...) Tarski's discussion concerning the distinction between material and formal consequence and the important question ofthe criterion for distinguishing between logical and non-logical terms.§1. Preliminaries. In this paper an argument is a two-part system composed of a set of propositions P and a single proposition c. The expression ‘c is a [logical] consequence of P’ is used with the same meaning as the expression ‘c is [logically] implied by P’. The expressions ‘is a logical consequence of’ and the converse ‘implies’ are relational. Often, I shall be talking in the same sense of validity of an argument. Validity is a property of arguments; an argument with premise-set P and conclusion c is valid if and only if P implies c; i.e., c is a logical consequence of P. Notice that this notion of argument is strictly ontic; it does not involve any agent that thinks, determines or establishes that a given proposition is or is not a consequence of a given set of propositions.

A system S has the “converse Ackermann property” if -> C is unprovable in S whenever C is a propositional variable. In this paper we define the fragments with the C.A.P. of some well-know propositional systems in the spectrum between the minimal and classical logic. In the first part we succesively study the implicative and positive fragments and the full calculi. In the second, we prove by a matrix method that each one of the systems has the C.A.P. Thus, we (...) think the problem proposed in Anderson & Belnap § 8.12 has been solved. (shrink)

As discussões a respeito do sagrado na contemporaneidade têm ganhado relevância ao considerarmos as novas perspectivas que se abrem com a inclusão de alguns temas relativos à diversidade cultural e religiosa na sociedade brasileira. Cada dia é perceptível o crescente espaço que o sagrado ocupa na vida cotidiana das pessoas comuns. A presença do sagrado no cotidiano da cultura brasileira é uma marca que realça um relevante aspecto da identidade nacional. A cultura brasileira é uma cultura plural. Para além das (...) matrizes indígenas e européias, existe uma grande variedade cultural no âmbito da africanidade. O presente artigo objetiva analisar como esse elemento sagrado de caráter afro-brasileiro aparece nos enredos das escolas de samba do Rio de Janeiro durante os carnavais de 2011 e 2012. Nosso referencial são as letras dos sambas-enredos das escolas dos grupos C, D, e E que desfilam na Intendente Magalhães, subúrbio do rio de Janeiro. Palavras-chave: Religiosidade. Africana. Sagrado. Carnaval. Rio de Janeiro.The discussions about the sacred in contemporaneity have gained importance in considering new opportunities opening up with the inclusion of issues related to cultural and religious diversity in Brazilian society.

There have been many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms, beyond merely providing the basis for the shapes and sizes of biological molecules and their chemical affinities. These range from Schr¨odinger’s suggestion that quantum fluctuations produce mutations, to Hameroff and Penrose’s conjecture that quantum coherence in microtubules is linked to consciousness. I review some of these claims in this paper, and discuss the serious problem of decoherence. I advance some further (...) conjectures about quantum information processing in bio-systems.

Offering an original perspective on the central project of Descartes' Meditations, this book argues that Descartes' free will theodicy is crucial to his refutation of skepticism. A common thread runs through Descartes' radical First Meditation doubts, his Fourth Meditation discussion of error, and his pious reconciliation of providence and freedom: each involves a clash of perspectives-thinking of God seems to force conclusions diametrically opposed to those we reach when thinking only of ourselves. Descartes fears that a skeptic could exploit this (...) clash of perspectives to argue that Reason is not trustworthy because self-contradictory. To refute the skeptic and vindicate the consistency of Reason, it is not enough for Descartes to demonstrate that our Creator is perfect; he must also show that our errors cannot prove God's imperfection. To do this, Descartes invokes the idea that we err freely. However, prospects initially seem dim for this free will theodicy, because Descartes appears to lack any consistent or coherent understanding of human freedom. In an extremely in-depth analysis spanning four chapters, Ragland argues that despite initial appearances, Descartes consistently offered a coherent understanding of human freedom: for Descartes, freedom is most fundamentally the ability to do the right thing. Since we often do wrong, actual humans must therefore be able to do otherwise-our actions cannot be causally determined by God or our psychology. But freedom is in principle compatible with determinism: while leaving us free, God could have determined us to always do the good. Though this conception of freedom is both consistent and suitable to Descartes' purposes, when he attempts to reconcile it with divine providence, Descartes's strategy fails, running afoul of his infamous doctrine that God created the eternal truths.
