Authors: Sonmez Cakir Fatma , Adiguzel Zafer
Published: November 2019

In the production sector, where innovation and creativity activities are intensely realized, organizations need not only creativity activities but also process management in a successful organizational culture in order to be successful in the competitive environment in terms of both leadership and innovation activities. In terms of leadership, institutions need to be managed with a correct understanding. The aim of this study is to analyze the relationships between open leadership, innovation orientation, employee creativity, organizational culture and process management variables. In this study, the effects of open leadership role on innovation and employee creativity activities and process management were investigated. At the same time, innovation orientation mediated effect was demonstrated. In the scope of aim of the study, a survey was conducted with 418 engineers working in the production sector. IBM SPSS 25 program, LISREL program and SOBEL calculation tool were used in the analysis. The data obtained were evaluated. Confirmatory and explanatory factor analysis and reliability analysis were performed on questions used Likert scale. In this study, it is concluded that the mediation variable effect of innovation orientation variable is on both organizational culture and creativity and process management.
Phase-space Correlation in Stellar Streams of the Milky Way Halo: The Clash of Kshir and GD-1*
Authors: Malhan Khyati , Ibata Rodrigo A. , Carlberg Raymond G. , Bellazzini Michele , Famaey Benoit , Martin Nicolas F.
Published: November 2019

We report the discovery of a

long stellar stream in the Milky Way halo, which criss-crosses the well known “GD-1” stream. We show that this new stellar structure (“Kshir”) and GD-1 lie at similar distance, and are remarkably correlated in kinematics. We propose several explanations for the nature of this new structure and its possible association with GD-1. However, a scenario in which these two streams were accreted onto the Milky Way within the same dark matter sub-halo seems to provide a natural explanation for their phase-space entanglement, and other complexities of this coupled system.
Lucia et son album de famille
Authors: Royer Anne-Marie
Published: November 2019

Le geste suicidaire d’une adolescente convoque toujours la frayeur de son entourage et doit apporter des réponses. Le cadre de soin proposé, mêlant abord systémique et approche psychanalytique, se veut souple et propice à l’élaboration d’un récit co-construit. Comme si elle feuilletait son album de famille, l’adolescente se fait l’auteur-compositeur de son histoire familiale, interrogeant les liens, les dépendances et les zones d’ombre, et traduisant ainsi les messages que ses parents lui ont transmis à leur insu. Le thérapeute, témoin-interprète, va faciliter par sa neutralité engagée, le processus de séparation-individuation qui permet à l’adolescente de s’appuyer sur sa famille pour mieux s’en dégager, prendre conscience de ses compétences et construire sa propre identité narrative.

From the tower to the pews: A call for academic theology to re-engage with the local context
Authors: Womack Jonathan M. , Pillay Jerry
Published: November 2019

This article assesses the shortcomings and the disconnectedness of the current academic theological education in South Africa. It offers a brief history to provide a guiding principle for academic theology. It then proceeds to show the current disconnect and challenges between academic theology and the church, with its primary focus on academic theology. Drawing on original research and reflection on these responses, commodification, euro-centricity and rankings are seen as three traps of modern academics. These three areas have distorted the true content of theological reflection. This article thus clearly highlights the current problem and motivates the need for academic theology and the local church to reconnect with each other. With this article focussing on academic institutions, it calls for the academy to change not in nature but in content, and to draw its content for the local context.

Nacionalidade: novas regras, velhos problemas
Authors: Nunes Paulo Henrique Faria
Published: November 2019

Este artigo visa analisar as lacunas e deficiências do sistema jurídico brasileiro concernente à nacionalidade. Embora a Constituição Federal tenha um capítulo específico sobre o assunto, regulado por normas infraconstitucionais, com destaque para a Lei de Migração (Lei 13.445/2017), existem problemas que merecem maior atenção de constitucionalistas e internacionalistas no Brasil. Elegeram-se como temas para análise mais específica o direito à nacionalidade de estrangeiros adotados por brasileiros; a extradição de brasileiros naturalizados por tráfico de drogas superveniente à naturalização; o conceito de atividade nociva, requisito necessário ao cancelamento da naturalização; e a diferença entre “cancelamento” e “declaração de nulidade” de naturalização”. A investigação tem natureza qualitativa e exploratória amparada em fontes primárias, bibliográficas e no direito comparado. Ao final, conclui-se: a Constituição brasileira necessita ser atualizada no tocante à nacionalidade decorrente de adoção transnacional; os constituintes brasileiros não tiveram bom senso nem adotaram boa técnica legislativa no tratamento do cancelamento da naturalização em virtude de tráfico de drogas; faltam padrões normativos claros definidores de atividade nociva, o que pode acarretar cancelamento arbitrário da naturalização.
O caso petruhhin e o princípio do nível mais elevado de proteção no tocante aos direitos fundamentais no âmbito da União Europeia
Authors: Demarchi Clovis , Suzin Jaine Cristina , Suzin Jaine Cristina
Published: November 2019

Na era da globalização, em que as relações sociais não estão mais limitadas por distâncias territoriais, em um mundo em que o poder estatal está sendo, sistematicamente, testado por poderes transnacionais, a cidadania, no entendimento clássico de pertencimento a um Estado passa a ser questionada e revisada, a ponto de ser possível juridicamente se pensar em múltiplas cidadanias. O presente trabalho tem por escopo entender como os direitos fundamentais são protegidos no âmbito do direito da União Europeia e, por consequência, qual o seu papel na evolução e solidificação da cidadania decorrente dos Tratados instituidores do processo de integração. Para tanto, um caso apreciado e decidido pelo Tribunal de Justiça da União Europeia (caso Petruhhin) será apresentado, tendo por base a aplicação do princípio do nível mais elevado de proteção dos direitos fundamentais. Observa-se que a livre circulação de pessoas implica muito mais do que a liberdade de ir e vir. Implica em um processo de integração. Implica em conceder um conjunto de direitos sem olvidar os deveres. Diferencia-se cidadania da União de nacionalidade dos Estados-Membros, e oportunizar o cidadão da União a fazer uso dos direitos fundamentais daí decorrentes até mesmo contra seu Estado-Membro, em uma relação de simbiose. Quanto a metodologia, utilizou-se o método indutivo com a prática da pesquisa bibliográfica e documental.
O comitê jurídico interamericano da OEA e a codificação do direito internacional regional
Authors: Lima Lucas Carlos
Published: November 2019

O presente trabalho irá avaliar se, e em qual medida, o trabalho do Comitê Jurídico Interamericano pode favorecer uma certa regionalização do direito internacional. Mais precisamente, o foco é na questão de saber se, e em qual medida, o trabalho do Comitê pode favorecer a emergência de regras regionais, não escritas, de caráter costumeiro. O trabalho será dividido em três partes. Primeiramente, será contextualizada a ideia de codificação na América Latina e, em particular, a noção de codificação no Continente Americano. Embora exista significante trabalho acadêmico na questão, revisitar este debate prova-se importante vez que é no interior dele que o primeiro comitê foi criado com a função de codificar o direito internacional. Na segunda parte, será examinado o método de trabalho do Comitê Jurídico Interamericano. Sobre a questão, será examinada se o Comitê favorece a promoção ou contribui para a ideia de regras de direito internacional aplicáveis apenas na relação entre Estados Americanos. O último problema analisado será aquele das interações entre o trabalho de codificação do Comitê Jurídico Interamericano e o da Comissão de Direito Internacional. O objetivo aqui será o de investigar e avaliar a relação entre a perspectiva regional e a perspectiva universal no processo de codificação, especialmente quando um determinado tópico é coberto por dois órgãos e potenciais conflitos podem emergir. O principal argumento sustentado é que, direta e indiretamente, o CJI favorece uma certa regionalização do direito internacional ao focar-se, particularmente em seus trabalhos recentes, na prática e na opinio juris dos Estados Americanos. Isto ocorre apesar da coordenação entre CJI e CDI.
Seismic waveform tomography of the Central and Eastern Mediterranean upper mantle
Authors: Blom Nienke , Gokhberg Alexey , Fichtner Andreas
Published: November 2019

Abstract. We present a seismic waveform tomography of the upper mantle beneath the Central and Eastern Mediterranean down to the mantle transition zone. Our methodology incorporates in a consistent manner the information from body and multimode surface waves, source effects, frequency dependence, wavefront healing, anisotropy and attenuation. This allows us to jointly image multiple parameters of the crust and upper mantle. Based on the data from ~ 17 000 unique source-receiver pairs, gathered from 80 earthquakes, we image radially anisotropic S velocity, P velocity and density. We use a multi-scale approach in which the longest periods (100–150 s) are inverted first, broadening to a period band of 28–150 s. Thanks to a strategy that combines long-period signals and a separation of body and surface wave signals, we are able to image down to the transition zone in most of the model domain. Our model shows considerable detail in especially the northern part of the domain, where data coverage is very dense, and displays a number of clear and coherent high-velocity structures across the domain that can be linked to episodes of current and past subduction. These include the Hellenic subduction zone, the Cyprus subduction zone and high-velocity anomalies beneath the Italian peninsula and the Dinarides. This model is able to explain data from new events that were not included in the inversion.
The Effect of Implementing MALL Applications on Learning Pronunciation of English by EFL Learners at Najran University
Authors: Yousef Mohammed Abduh Mariam
Published: November 2019

Currently, the advancement in technology and communication has significantly influenced the field of education. As a part of this development, the use of mobile phones is being considered as a substantial source of learning for EFL learners. This study was conducted to investigate the effect of mobile phones on students’ pronunciation skill. The participants in this study were 48 female native speakers of Arabic enrolled in the English Department at Najran University, Saudi Arabia. They were divided into two groups; namely the control group (learning without mobile phones) and the experiment group (learning with mobile phones) with 24 students for each group. The obtained data were analyzed using t-test and it showed that the posttest performance development mean and standard deviation of the participants in the experiment group equaled 23.333, and 6.58501, respectively. However, the com­puted posttest performance development mean and standard deviation of the participants in the control group equaled 17.9167, and 6.37193, respectively, which indicates that there is a significant difference be­tween the experiment group and the control group in terms of overall performance. So, it can be concluded that the results ap­proved the significant impact of using MALL technology in improving the pronunciation of EFL learners.
An exploratory study of voicing-related differences in vowel duration as compensatory temporal adjustment in Italian and Polish
Authors: Coretta Stefano
Published: November 2019

Over a century of phonetic research has established the cross-linguistic existence of the so called “voicing effect”, by which vowels tend to be shorter when followed by voiceless stops and longer when the following stop is voiced. However, no agreement is found among scholars regarding the source of this effect, and several causal accounts have been advanced. A notable one is the compensatory temporal adjustment account, according to which the duration of the vowel is inversely correlated with the stop closure duration (voiceless stops having longer closure durations than voiced stops). The compensatory account has been criticised due to lack of empirical support and its vagueness regarding the temporal interval within which compensation is implemented. The results from an exploratory study of Italian and Polish suggest that the duration of the interval between two consecutive stop releases in CVCV words in these languages is not affected by the voicing of the second stop. The durational difference of the first vowel and the stop closure would then follow from differences in timing of the VC boundary within this interval. While other aspects, like production mechanisms related to laryngeal features effects and perceptual biases cannot be ruled out, the data discussed here are compatible with a production account based on compensatory mechanisms.

Exploring Opportunities for Performance Improvement in a Global Climate Model
Authors: Costa Rhuan , Mendes Celso Luiz
Published: November 2019

The Brazilian Earth System Model (BESM) is a Global Climate Model (GCM) developed by the Brazilian National Institute for Space Research (INPE). The main purpose of a GCM is to simulate Earth’s climate in a decadal or centennial scale. The simulations usually include representations of the main elements of the Earth, such as atmosphere, ocean, ice and land. Since its first release, BESM has provided support materials for contributions to the Intergovernmental Panel on Climate Change (IPCC). This paper evaluates BESM’s performance and explores optimization possibilities, aiming to speed up the model execution. Our study started with a detailed analysis that characterized the performance of BESM executions on hundreds of processors, which served to reveal the major performance bottlenecks. Next, we worked on schemes to mitigate some of those bottlenecks. The changes made so far resulted on performance gains up to a factor of 4 in some cases, when compared to the way it was previously being executed in production. We also describe ongoing work towards additional performance improvements. Despite presenting results only for BESM, our optimization techniques are applicable to other scientific, multi-physics models as well.

Heterogeneous Parallel Architecture for Inverted Index Generation
Authors: Silveira Tiago , Soares Felipe , Brandão Wladmir , Freitas Henrique Cota
Published: November 2019

The amount of data generated on the Web has increased dramatically, as well as the need for computational power to prepare this information. In particular, indexers process these data to extract terms and their occurrences, storing them in an inverted file, a compact data structure that provides quick search. However, this task involves processing of a large amount of data, requiring high computational power. In this article, we present a heterogeneous parallel architecture that uses CPU and GPU in a cluster to accelerate inverted index generation. Experimental results show that the proposed architecture provides faster execution times, up to 60 times in classification and 23 times in the compression of 1 million elements.

Estudo de viabilidade do uso de Raspberry PI na Névoa
Authors: Silva Guilherme , Lago Nelson , Cavalheiro Gerson Geraldo , Goldman Alfredo
Published: November 2019

Em função da necessidade de se ter baixa latência em muitas aplicações e visando uma melhor usabilidade para o usuário final, nasce o paradigma de névoa, que traz o processamento ou pré processamento para um local mais próximo ao usuário. Buscando reduzir o consumo energético, optou-se pelo uso de dispositivos de baixa capacidade, dado seu propósito geral, baixo consumo e custo, além da disponibilidade no mercado. Este trabalho tem como objetivo investigar a Raspberry Pi 3 como dispositivo para névoa, avaliando seu uso através do benchmark NDBench realizando operações de escrita e leitura em um banco de dados NoSQL. Os resultados indicam a viabilidade da Raspberry em cenários onde são esperadas em torno de até 1.200 operações por segundo com latência média de 500ms, o que contempla uma grande quantidade de aplicações e demonstra que a Raspberry pode ser usada em ambientes de nuvem e névoa.
Coherence State Awareness in Way-Replacement Algorithms for Multicore Processors
Authors: Souza Matheus , Freitas Henrique Cota , Pétrot Frédéric
Published: November 2019

Due to their performance impact on program execution, cache replacement policies in set-associative caches have been studied in great depth. Currently, most general-purpose processors are multi-core, and among the very large corpus of research, and much to our surprise, we could not find any replacement policy that does actually take into account information relative to the sharing state of a cache way. Therefore, in this paper we propose to add, as a complement to the classical time-based related way-selection algorithms, an information relative to the sharing state and number of sharers of the ways. We propose several approaches to take this information into account, and our simulations show that LRU-based replacement policies can be slightly improved by them. Also, a much simpler policy, MRU, can be improved by our strategies, presenting up to 3.5× more IPC than baseline, and up to 82% less cache misses.

A structural testing tool for MPI programs with loops
Authors: Diaz Silvia Diaz , Souza Paulo Lopes , Souza Simone
Published: November 2019

Há uma alta demanda por programas paralelos corretos, principalmente devido às arquiteturas paralelas atuais, como clusters e processadores multi/many cores. O teste estrutural permite identificar defeitos pela cobertura de estruturas internas de programas paralelos. O não determinismo em programas paralelos traz novos desafios ao teste estrutural. Ele requer ferramentas e modelos de teste especı́ficos, capazes de cobrir primitivas de comunicação e sincronização com comportamentos dinâmicos, tais como os presentes em loops. Este artigo propõe uma nova ferramenta de software para o teste estrutural, com o objetivo de auxiliar testadores na revelação de defeitos desconhecidos associados a comunicação e presentes em estruturas de repetição de programas paralelos em C/MPI. Baseando-se na cobertura obtida, testadores podem escolher casos de teste especı́ficos e avaliar o progresso da atividade de teste. A ferramenta de teste proposta é validada com a ingestão de defeitos no código de um programa, e com a análise do suporte dado pela ferramenta para a geração de elementos requeridos e seleção de casos de teste. A ferramenta proposta automatiza parte da atividade de teste, especificamente a geração de elementos requeridos e guia a execução dos testes, reduzindo o tempo para a aplicação da atividade de teste. Nossos resultados mostram que a ferramenta de teste é capaz de revelar defeitos desconhecidos em primitivas de comunicação presentes em iterações de loops. There is a growing demand for correct parallel programs, mainly due to nowadays parallel architectures, such as clusters and multi/many-core processors. Structural testing allows the identification of defects by covering internal structures of parallel programs. Nondeterminism in parallel programs brings new challenges to the structural testing. It requires specific test model and tools, capable to cover communication and synchronization primitives with dynamic behaviors, such as those present inside of loops. This paper proposes a novel software tool for the structural testing, aiming to help testers in revealing defects associated to communication present in repetition structures of C/MPI parallel programs. Based on the obtained coverage, testers can choose specific test cases and evaluate the progress of the testing activity. We validate the proposed testing software tool by injecting a defect in a program code, and analyzing the support for generation of required elements and selection of test cases. ValiMPI tool automates part of the test activity, specifically the generation of required elements to guide test case selection, reducing the application cost of the testing activity. Our results demonstrate that the testing tool is capable to reveal unknown defects from communication in different loop iterations.

Davidson and Indeterminacy of Meaning
Authors: Baghramian Maria
Published: November 2019

According to Quine's thesis of the indeterminacy of translation there are no facts of matter which could determine the choice between two or more incompatible translation schemes which are in accordance with all behavioral evidence. Donald Davidson agrees with Quine that an important degree of indeterminacy will remain after all the behavioral evidence is in, but he believes that this indeterminacy of meaning (IM) should not be seen as either mysterious or threatening. In this paper I argue that IM is not as innocuous as Davidson believes it to be and has consequences which do not sit easily with some core elements of the Davidsonian project. I argue that IM leads to the nontrivial thesis of the indeterminacy of language ascription which is not captured by the mundane examples of indeterminacy of measurement that Davidson frequently cites. Davidson makes a liberal use of the principle of charity in order to lessen the effect of IM. In recent years he has broadened the scope of the principle of charity by arguing that a radical interpreter, at least in some basic cases, should identify the object of a belief with the cause of that belief. Davidson agrees with Quine and Putnam that the concept of causality is applied to the world according to human interests. For Quine and Putnam, however, the interest-relativity of causal relations has relativistic consequences. Given Davidson. s long-standing opposition to all types of relativism this conclusion should not be welcome to him. Relativism may be avoided by imposing a great deal of social and biological homogeneity on all language-users which is an equally unwelcome view.
Wittgenstein’s 1913 Objections To Russell’s Theory of Belief
Authors: Carey Rosalind
Published: November 2019

In what follows, I give (following Burton Dreben) a dialectical reading of his dismissal of metaphysics and of Wittgenstein's objections to Russell in 1913. I argue that Wittgenstein must be read as advocating no particular theory or doctrine — that is, philosophy is an activity and not a body of truths. Furthermore, this insistence is thoroughgoing. Put differently, a dialectical reading must be applied to one's own thought and talk. Characteristically, this sort of dialectical philosophy begins with the question, Is there any definiteness to what I am doing in my own thinking and speaking? Such a question undercuts the easy assumption that what we are doing may be expressed in a body of meaningful statements. In particular, I argue that Wittgenstein does not advocate any particular theory of language. A common reading of Wittgenstein is that he aims to prevent us from misusing language. This view assumes that, for Wittgenstein, the notion of a correct, acceptable or meaningful use of language may be taken for granted. In my view, Wittgenstein does not take the notions of use of language and grammar and its misuse for granted. For Wittgenstein grammar underdetermines what it is to use or misuse language. I argue that an ethical critique is implicit in Wittgenstein's objections to any attempt to speak a priori about language and thought.
Kripkenstein: Rule and Indeterminacy
Authors: Liu Xin Sheen
Published: November 2019

Indeterminacy theories, such as Wittgenstein's and Kripke's indeterminacy principle on rules and language and Quine's indeterminacy of radical translation, raise some fundamental questions on our knowledge and understanding. In this paper we try to outline and interpret Wittgenstein's and Kripke's indeterminacy, and then compare it to some other related theories on indeterminacy of human thinking, such as raised by Hume, Quine, and Goodman.
Universalizability and Philippine Jurisprudence
Authors: Fernando Emmanuel Q.
Published: November 2019

The requirement that legal reasoning be universalizable is so unquestioned as a legal doctrine that it is practically axiomatic. Recently, two Philippine Supreme Court cases have been decided in a manner that apparently dispenses with this requirement. I discuss these two cases in the light of the requirement. I conclude that the requirement, rather than being diminished by the two cases, has actually maintained its axiomatic status on the basis that the reasoning in the two cases is deficient: the first either for inequality in treatment or for lack of clear guidance, and the second for the failure to appear impartial.
Pluralism and the Universality of Rights

The problem of the coexistence of cultures arises inside modern societies that have a constitutional set-up expressed by 'pluralism.' Their central problem lies in the relationship between individuality and sociality, freedom and order. The function of law is to transform absolute pluralism into a relative pluralism limited by fundamental common interests, thus overcoming the problems that arise from the variety of different views of the world and from different values. In the context of H. Kelsen's Reine Rechtlehre, we ask: 1. Do pre-positive legal grounds exist that can claim to have universal validity under the conditions of pluralism? 2. Can the demand for pre-positive principles of law be compatible with renouncing particular material assertions of values on which no agreement can be reached and replacing them with the universally valid formal principles demanded in pluralistic democracies?
Semantic Realism
Authors: Landry Elaine
Published: November 2019

I argue that if we distinguish between ontological realism and semantic realism, then we no longer have to choose between platonism and formalism. If we take category theory as the language of mathematics, then a linguistic analysis of the content and structure of what we say in and about mathematical theories allows us to justify the inclusion of mathematical concepts and theories as legitimate objects of philosophical study. Insofar as this analysis relies on a distinction between ontological and semantic realism, it relies also on an implicit distinction between mathematics as a descriptive science and mathematics as a descriptive discourse. It is this latter distinction which gives rise to the tension between the mathematician qua philosopher. In conclusion, I argue that the tensions between formalism and platonism, indeed between mathematician and philosopher, arise because of an assumption that there is an analogy between mathematical talk and talk in the physical sciences.
The Concept of Intelligence
Authors: Altman Ira
Published: November 2019

Gilbert Ryle’s dispositional analysis of the concept of intelligence makes the error of assimilating intelligence to the category of dispositional or semi-dispositional concepts. Far from being a dispositional concept, intelligence is an episodic concept that refers neither to dispositions nor to ‘knowing how,’ but to a fashion or style of proceeding whose significance is adverbial. Being derivative from the function of the adverb ‘intelligently,’ the concept of intelligence does not have essential reference to specific verbs but rather to the manner or style of proceeding of nearly any verb that is descriptive of the proceedings of an agent. Intelligence- words are expressive of a manner of doing things that may be narrated in one of two ways. The first takes the form of a series of contrasts which, when put together as a list of disjuncts, may be called the contrast-criteria of intelligence. The second may take the form of the characteristic activities which comprise the criteria of intelligence.
Simulation, Folk Psychological Explanation, and Causal Laws
Authors: Arkway Angela J.
Published: November 2019

The assumption that commonsense psychological explanations of behavior are causal underlies current debate between simulation theory and theory theory regarding the nature of cognitive mechanism responsible for our folk psychological practices. Theory theorists claim that these explanations are subsumed by the covering law model of causal explanation. Simulationists are not explicit about the nature of the explanations produced by simulation. In what follows, I propose a set of plausible conditions that a correct causal simulation-produced folk psychological explanation will satisfy and point out two prima facie problems. In discussing a possible solution, I discover that the latter incurs the need for some sort of causal law. An examination of two likely candidates for these laws reveals that neither is capable of playing the role required. I then suggest alternative routes that simulationists might explore in order to provide simulation theory with a sorely-needed account of the nature of the explanations produced by simulation.
Problems of Mind as Action
Authors: Demjançuk Nikolaj
Published: November 2019

A large body of current literature details significant recent advances in our understanding of the mind. This boom has partly been stimulated by the explosive growth of cognitive science dedicated to advancing scientific understanding. This paper focuses on the nature of philosophical theory of mind, and seeks to find ways of talking about mind. Central to my argument is developing a description of mind as action. Concessive behaviorism depicts the mind as presented in complexes of actions and tendencies to act. If a philosophical theory of the mind emphasizes waving over silent cogitations and brain events, then it is behaviorist. This position defines the eliminative behaviorism. The most powerful and straightforward kind of non-eliminative behaviorism is analytic behaviorism arising from the view that all statements containing mental vocabulary can be analyzed into statements containing just the vocabulary of physical behavior. But perhaps a better way to think of beliefs is to understand only what each of them does, which is at the heart of the view known as functionalism. Therefore, special attention is given to considering behaviorist and functionalist theories.
The Self-Knowledge That Externalists Leave Out
Authors: Hall Lisa L.
Published: November 2019

This paper addresses the relationship between self-knowledge, practical reason and Externalist theories of mind. Specifically, I argue that the kind of self-knowledge defended by Externalists is insufficient for intentional action. I claim that we know how to act only if we have access to beliefs about how our circumstances are related to our intended actions. I then go on to argue that the kind of mental content we need to characterize these beliefs is incompatible with the Externalist’s assumptions.
In Defense of Direct Perception
Authors: Hudson Robert
Published: November 2019

My goal in this paper is to defend the claim that one can directly perceive an object without possessing any descriptive beliefs about this object. My strategy in defending this claim is to rebut three arguments that attack my view of direct perception. According to these arguments, the notion of direct perception as I construe it is objectionable since: (1) it is epistemically worthless since it leaves perceived objects uninterpreted; (2) it cannot explain how perceived objects are identified; and (3) it is ill-prepared to assign objective content to perceptual states.
La cuestión de la Sistematicidad en el Análisis Computacional de la Mente
Authors: Lo Monaco Vincenzo P.
Published: November 2019

Fodor, Pylyshyn and McLaughlin reject connectionism and argue that connectionists are unable to explain systematicity without implementing a classical architecture. In this paper, I contend that the traditionalist conclusion only seems to follow if they are able to sketch a neutral account of systematicity. But in absence of such an explanation, connectionists bear no special burden in this matter. In support of this view, I set out three specific weaknesses: circularity, epistemological insufficiency, and atomism/reductionism, which affect the classical argument of systematicity. I conclude that there may be other ways to accommodate systematicity in a scientific framework, for instance, in the manner of Davidson’s holistic semantics, and indeed connectionist representation is one of these legitimate ways for doing that.
About Specific Processing of Mind at the Period of Revaluation
Authors: Shevstov Sergei
Published: November 2019

A new situation is always a discovery. It allows us to see old problems in a new light. The philosopher’s main task is to find new situations. The consciousness of the millions of people living in the countries of the former Soviet Union can be considered new in all senses, except one. Nevertheless the exception gives rise to serious difficulties. Essentially, a situation is always new since none of Aristotle’s kinds of identity can be used for it. At the same time, this same situation can never be new since anything similar must have taken in human history. It is up to the philosopher to see the situation from a new point of view. Now we can observe the changes and its effects. The collapse of the old ideology did not create the changing of mass consciousness per se, because the latter had already taken a skeptical attitude toward it. The real change of mass consciousness began with the change of real human practice. When former engineers, teachers, scientists, and industrial workers clashed with the necessity to support themselves and their families, it was always as an alternative to starting all over again — the option of relying only on themselves or continuing to rely on the state system to do their usual work in the hopes of receiving an illusory reward in the future.
Consciousness and Intentionality of Action
Authors: Sundström Pär
Published: November 2019

One much discussed issue in contemporary philosophy is the relation between consciousness and intentionality. Philosophers debate whether consciousness and intentionality are somehow ‘connected’; whether we have reason to be more optimistic about an ‘objective,’ ‘scientific’ or ‘third person’ ‘account’ of intentionality than about an analogous account of consciousness. This paper is intended as a limited contribution to that debate. I shall be concerned only with the intentionality of action. Not everything which is true of intentionality of action is true of intentionality of other phenomena, such as beliefs. I shall discuss the question, ‘What is the intentionality of action?’ More specifically, I shall discuss one partial answer to this question: that a necessary condition of an agent performing a certain intentional action is that the agent is conscious of performing that action. This answer is fairly unpopular in contemporary philosophy. In this paper, I shall try to say something about the ground for the rather wide-spread philosophical resistance to the answer, and I shall also outline the kind of considerations that I think are required to judge whether a wedge can or cannot be driven between consciousness and intentionality of action.
Functional Irrationality
Authors: Tjiattas Mary
Published: November 2019

The view that some forms of irrationality may serve a useful purpose is being increasingly entertained despite the disquiet it elicits. The reason for the disquiet is not difficult to discern, for if the view were made good it might threaten the unqualified normative primacy that rationality enjoys in the evaluation of thoughts, beliefs, intentions, decisions, and actions. In terms of the predominant ‘rational explanation’ model, reasons both generate and justify actions, and carrying out the dictates of reason is held up as an ideal. If it can be shown that under some circumstances or for certain types of actions irrational elements or procedures would produce ‘all things considered’ better results, this would put these deliberative ‘ideals’ in question.
Why Granny Should Have Read French Philosophers
Authors: Wolf David F.
Published: November 2019

In 1983, Fodor’s Modularity of Mind popularized faculty psychology. His theory employs a trichotomous functional architecture to explain cognitive processes, which is very similar to Merleau-Ponty’s phenomenology of perception. Each theory postulates that perception is a mid-level procedure that operates on transduced information and that perception is independent of our cognitive experience. The two theories differ on whether perception is informationally impenetrable. This difference is essentially an empirical matter. However, I suggest that Merleau-Ponty’s allowance of cross-modal communication within perception explains our ability to identify features in noisy backgrounds better because his theory offers a more definitive ontology that matches human substantive behavior. Likewise, evidence within cognitive science suggests that Merleau-Ponty’s phenomenology is a more accurate depiction of human cognitive processes.
