The minimal perimeter enclosing N planar regions, each being simply connected and of the same area, is an open problem, solved only for a few values of N . The problems of how to construct the configuration with the smallest possible perimeter E and how to estimate the value of E are considered. Defect-free configurations are classified and we start with the naïve approximation that the configuration is close to a circular portion of a honeycomb lattice. Numerical simulations and analysis (...) that show excellent agreement to within one free parameter are presented; this significantly extends the range of values of N for which good candidates for the minimal perimeter have been found. We provide some intuitive insight into this problem in the hope that it will help the improvement in future numerical simulations and the derivation of exact results. (shrink)

Neste texto pretendo dizer alguma coisa sobre a criação, referida por Porchat como uma epopeia, e consolidação do CLE e do Programa de pós-graduação em Filosofia da UNICAMP. O Prof. Porchat chegou à UNICAMP, em 1975, e trouxe consigo um pequeno projeto, que submeteu ao então reitor da Unicamp, Prof. Zeferino Vaz. A proposta contemplava a implantação de um Centro de estudos e pesquisas nas áreas de Lógica, Epistemologia e História da Ciência bem como a criação de um programa de (...) pós-graduação em Lógica e Filosofia da Ciência. Tal projeto, além de preencher uma grande lacuna, converteria a Unicamp, na década de setenta, num local privilegiado de encontro e diálogo entre filósofos, lógicos, historiadores, sociólogos, matemáticos, físicos, psicanalistas até então dispersos nos vários centros universitários do país. O Prof. Zeferino entusiasmou-se com a ideia já na primeira reunião e meses depois uma dezena de filósofos já havia sido contratada para a implantação do CLE e também do Curso de Pós-Graduação em Lógica e Filosofia da Ciência junto ao Departamento de Filosofia. A marca que o Prof. Porchat imprimiu neste programa, neste período, e que o caracterizava era a atmosfera de debate e de discussão que se instalou ali. (shrink)

This essay is a conversation between two South Asian Muslim sisters both of whom are feminist academics of color, where one immigrated to the United States and the other, a decade apart, to United Kingdom. The aim of this essay is to examine the ways in which white supremacist structures influenced and molded our personal journeys as well as how our narratives are deeply entangled within broader conversations around patriarchy, neo-liberal feminism, and anti-Muslim racism.

Background: The castor bean is a large grassy or semi-wooden shrub or small tree. Any part of the castor plant parts can suffering from a disease that weakens the ability to grow and eliminates its production. Therefore, in this paper will identify the pests and diseases present in castor culture and detect the symptoms in each disease. Also images is showing the symptom form in this disease. Objectives: The main objective of this expert system is to obtain appropriate diagnosis of (...) the disease. Methods: In this paper, the expert system is designed for the ability of agricultural engineers to detect and diagnose disease of castor like as: seeding blight, alternaria blight, cercospora leaf spot, powdery mildew and wilt. This system presents the disease symptoms, survival and spread, favorable conditions and image for each disease. Clips and Delphi expert system languages are used for designing and implementing the proposed expert system. Results: The expert system in the diagnosis of castor diseases was assessed by farmers and agricultural engineers and they were satisfied and accepted with its quality of performance. Conclusions: The expert system is easy for farmers and people have experience in the plant of castor to detect and diagnosis the symptoms that may face this plant from several disease. (shrink)

Este artigo procura apresentar algumas considerações acerca do entrecruzamento do pensamento político de Hannah Arendt e a questão ambiental. Para tanto, o seguinte questionamento servirá de guia para a reflexão aqui pretendida: se o âmbito natural é perturbado pelas ações humanas, é razoável a crença de que a própria ação humana possa ser capaz de frear o atual cenário de catástrofe? Assim sendo, assume-se, aqui, como procedimento metodológico uma análise bibliográfica que recorre ao livro A condição humana (The human condition, (...) 1958 [2010]) e alguns ensaios da coletânea Entre o passado e o futuro (Between Past and Future, 1961 [2009]). De modo geral, busca-se desenvolver o argumento de que embora não se possa enquadrar Hannah Arendt no rol das “historiadoras das ciências”, tampouco uma “pensadora da ecologia”, é certo que ela nunca deixou de se interessar e comentar os eventos científicos de seu tempo, bem como de se preocupar com as consequências das ações humanas. Logo, os assuntos relacionados aos avanços tecnológicos e científicos constituem assuntos de primeira grandeza e importância tanto para o mundo quanto para a política. Em suma, pretende-se sustentar a hipótese de que para Hannah Arendt, a imagem adotada da natureza – ao menos desde a época moderna –, e as ações humanas cometidas a partir desta compreensão, afetam diretamente nossa existência política.

D'un projet initié dans les quartiers populaires, qui y articulerait en? n l'ancrage dans la terre et la liberté de circuler. D'un projet dont le regard serait tourné vers l'Afrique et qui viserait à établir un large front internationaliste contre le réchauffement climatique et la destruction du vivant. D'un projet qui ferait de la Méditerranée un espace autonome et (...) un point de ralliement des mutineries du Nord comme du Sud. D'un projet se donnant comme horizon à la fois la libération des terres, la libération animale et l'égale dignité humaine, fondamentalement liées. D'un projet assumant la sécession face à des forces d'extrême droite toujours plus menaçantes. D'un projet permettant de prendre le large en quête du One Piece, le fameux trésor du manga éponyme, devenu symbole, dans les quartiers populaires, de la soif de liberté qui y gronde. D'un projet qui se mettrait à hauteur d'enfants et chercherait leur bien-être et leur libération. Ce projet, c'est celui de l'écologie pirate. (shrink)

Restorativeness is defined as the potential of the environment to re-establish certain cognitive capacities related to human information processing. The most frequently used instrument for evaluating the restorativeness of places is the Perceived Restorativeness Scale, proposed by Hartig and colleagues (1991). Later on, shorter versions of the Perceived Restorativeness Scale were proposed. The aim of this work is to evaluate the discriminatory capacity of the original and of a shorter Spanish version of the PRS, considering urban settings previously selected for (...) having different level of restorativeness, according to expert’s criteria. The study involved 244 students and used a 3 x 2 mixed experimental design, with two independent variables: Restorativeness of a place (between-subjects), which was manipulated by showing pictures of settings selected with varying levels of restorativeness (high, medium, low), and length of the scale (within-subjects), which was manipulated by asking subjects to fill in both the original and a shorter version of the PRS. The order of presentation of the two scales was counterbalanced. Results show an appropriate reliability for both version of the scale. Items of being-away, fascination, and coherence of the shorter scale correlate more strongly with the corresponding factor of the original scale, compared to the others factors. Both scales produce similar values for the perceived restorativeness of the different places, except for places with low restorativeness. (shrink)

O presente artigo propõe refletir sobre a vivência ético-política-afetiva na comunidade. Discute-se três pontos principais: 1. Como se dá a ética, a política e os afetos em uma comunidade a partir da Filosofia de Espinosa. 2. Partindo-se da compreensão da dinâmica dos afetos como se pode compreender a liberdade e a servidão na vivência comunitária. Como a comunidade age ou não de tal forma que a liberdade ou a servidão, respectivamente, passam a ser vivenciadas no ambiente comunitário? O que poderá (...) favorecer a liberdade ou a servidão? 3. Proposta de uma ação compartilhada dos profissionais. O objetivo dessa análise é revisitar a reflexão sobre ética, política e afetos na comunidade e, a partir de Baruch de Espinosa, proporcionar uma análise que reatualize o que seja comunidade na perspectiva essa revisitação. O conceito de comunidade que esse artigo se refere diz respeito ao conjunto de pessoas que convivem no mesmo território ou no mesmo bairro e que, no quotidiano, vivenciam diversas experiências. Tem-se como reflexões principais que, mediante a compreensão da dinâmica instável dos afetos, os profissionais que ‘atuam’ em comunidades, poderão ter uma visão mais ampla sobre suas práticas e se as mesmas fomentam ou aumentam estados de servidão ou se, ao contrário, contribuem para a liberdade da comunidade e dos indivíduos.

The studies presented here apply the concept of entitativity in order to understand how belonging to a particular geographical area – neighborhood - can determine the way others organize information and form impressions about area’s residents. In order to achieve this objective, three studies were carried out. The first study aims to verify if a neighborhood varies in terms of perceived entitativity, and identify the physical and social characteristics of the neighborhoods that are more strongly associated with the perception of (...) entitativity. The Study 2 and 3 used an experimental paradigm to explore how people’s perceptions of neighborhoods’ entitativity influenced their impressions of residents. To activate stereotypes, Study 2 used the name of real neighborhoods, and Study 3 employed only a set of pictures of unknown neighborhoods. The results show that the neighborhoods vary significantly with the regard to the perception of entitativity, and a set of physical attributes of place were strongly related with entitativity. The results showed that, independent of stimuli, the neighborhoods perceived as highly entitative, the supposed residents were subject to more extreme and quicker trait judgments, supported by greater confidence on the part of perceivers. Study 3 also reported that in highly entitative neighborhoods, the perceivers transferred more traits from the group to individual members. These results provide strong evidence that physical structure of neighborhoods imply different entitatity judgments that influences the way in which residents are perceived. (shrink)

RESUMO Este artigo procura mostrar como a linguagem e o estilo empregados por Dostoiévski já em seu romance de estreia, Gente pobre, contribuíram para a grande inovação realizada por ele na forma literária. Ao tomar como objeto de representação a realidade prática de camadas inferiores da sociedade e adotar em sua obra uma linguagem também considerada de nível inferior, própria à maneira de se expressar dessas camadas sociais, Dostoiévski não só transcende todas as regras literárias estabelecidas como também as já (...) transgredidas até então, porque ele leva a sério não só a realidade cotidiana como a linguagem, o nível de estilo próprio a elas. Com isso ele se aproxima da representação séria e elevada da realidade cotidiana sem mudar as regras de estilo, como fizeram os franceses. O que ele muda é o ponto de vista, o foco narrativo, de um modo que não encontra precedente nem mesmo na literatura Ocidental. ABSTRACT This article seeks to show how the language and style employed by Dostoevsky since his debut novel, Poor Folk, contributed to the great innovation that he introduced into literary form. By adopting the practical reality of the lower strata of society as his object of representation and, accordingly, a low-style language, Dostoevsky transcended all established literary rules, as well as others that were already being transgressed. He took seriously both the reality of everyday life and its language, the style level proper to it. In so doing, he approached the serious and elevated representation of everyday reality without changing the rules of style, as the French did. What he changed is the point of view, the narrative focus, and he did so in a way that had no precedent even in Western literature. (shrink)

In The Piano Tuner of EarthQuakes, the Quay Brothers' second feature, the sensual form and the meta-artistic content are truly interweaved, and the siblings' staple animated materials become part of the theme itself. Using Michel Serres's argument in Les cinq sens, I address the relationship between the Quays intermedial animation and the way the art forms of music, painting, theatre and sculpture are used to captivate the film viewer's sensorium in the same way that some of the characters are fascinated (...) by the evil Droz, a scientist and failed composer who manipulates machines and people alike, among them Felisberto, a meek piano tuner with the ability to stir the natural elements. I further proceed to posit the entire film as an intended allegory of animation on the Quays part. Their haptic construction of a three-dimensional world which they control artistically is replicated in the film in Droz's and Felisberto's activities vis-à-vis Malvina van Stille, an abducted opera diva who is kept in a suspended animation state and several hydraulic automata with musical resounding properties, some of them made up of an uncanny assortment of body parts. The artificial life of these creatures is contrasted, in two ways, with their physical reality as beings that exist in the world: first, via Serres's sensorial strategy to transform a body into a conscious entity, an embodiment I call 'Corpo-Reality', and second, by resorting to Deleuze and Guattari's theory of the body without organs in its advocacy of 'hard' nature and the rejection of a rigid assortment of body parts. The paradoxical organic objectivity of the 'marionettized' Malvina is pitted against the seemingly subjective doings of the mechanical automata, especially an android woodcutter. However, just as in the story things are not what they seem, and the automata actually reflect the 'real' world of Felisberto's tuning of them, so the film itself can be a 'crystal-image', offering itself to the senses of the spectator.

This paper is a critique of the present mode of capitalist democracy from the ethico-moral viewpoint. The crisis of values is identified as the great bane of free market-led globalization. This trend has aggravated worldwide inequality, promoted terrorism and violence, created psychological anomie and triggered eco logical disasters. Only a few business interests in the wealthier economies are gaining at the expense of humankind. The moral dimension of the government's role has been undermined by such profit-making free market gospel. The (...) author contends that more than beingjust secular, democracy is a pre-social moral force and, as such, is perceived more proximately in the religious temper of a non-industrial society than in a mass industrial society. In the latter democracy is almost a farce with the periodic ritual of public voting as its main act. The paper castigates the global economy and global media which cleverly mastermind our lives, and pleads for a change of values which will make humans self-conscious and will restore their autonomy.

Dans cet article nous proposons une définition de l’éthique de la gestion et nous en identifions les conditions à travers une revue de la littérature. Nous postulons par la suite que l’éthique de la gestion diffère selon qu’il s’agit d’organisations publiques ou d’organisations privées. Nous montrons en effet que pour l’organisation privée, l’éthique est un engagement subjectif qui permet de pallier les lacunes d’une gestion instrumentale sans remettre en question les finalités premières de l’organisation. Tandis que pour l’organisation publique, l’éthique (...) a une essence positive et se trouve orientée vers la recherche de compromis sur les finalités mêmes de l’organisation. (shrink)

My aim in this paper is to carve out a political understanding of the Muslim identity. The Muslim identity is shaped within a religious mold. Inseparable from this religious understanding is a political one that is valuable in its own right in order to secure any sustainable possibility of participating politically as Muslims within a democratic liberal democracy, such as the United States. Here I explore not the historical or theological formation of the Muslim identity, rather a metaphysical understanding of (...) it, in order to mobilize politically while avoiding the traps of essentialism. I begin with a brief overview of the early understandings of the term “identity politics” in the United States. Moving beyond interest-based movements I explore María Lugones' particular understanding of the self as multiplicitous. I then offer examples of the Muslim identity within the context of a social movement and individualist claims, in order to draw out the political aspects of the Muslim identity. In the final section I argue that the theological criteria that define “who counts as a Muslim” is a crucial aspect of how many Muslims may understand their identity as Muslims. However, I claim that in order to avoid the traps of marginalization of Muslim minorities, one must understand oneself as a multiplicitous political agent and that, furthermore, such an understanding is not at odds with Islam or one's own understanding of their identity as Muslim.

The precise nature of microaggression purposely obscures the exploration of the intentionality of perpetrator and the quantification of the harm committed. The act fits neatly into a system that privileges some and validates their reality to themselves and to us. This paper explores microaggression and recommends strategies for avoiding its harms.

The study assessed the role of childhood religiosity in adult religiosity and learning motivation in university participants. Participants were 338 university students (mean age = 20.42, SD = 1.53, 47% men) selected from Islamic (50%) and general universities (50%). The findings showed that participants from Islamic university compared to those from general universities scored higher on religious altruism among religiosity outcomes and on self-efficacy and active learning strategies among learning motivation outcomes. The hypothesized associations between childhood religiosity, religious altruism, religious (...) practice, and specific learning motivation outcomes were significant. Childhood religiosity predicted two learning motivation outcomes, self-efficacy and active learning strategies, and only religious altruism in the presence of religious practice mediated these associations. In addition, university status moderated these mediated associations with stronger indirect effects for participants from Islamic universities compared to those from general universities. (shrink)

This study has proposed to apply change leadership as a vehicle forward for sustaining the growth of the tourism industry to eradicate poverty through the Pakistani tourism industry. Applying a mixed method approach, this article has attempted to uncover the role a change leader can play to help achieve the United Nations’ sustainable development goals of poverty reduction. In this study, one of the authors interviewed stakeholders of the tourism industry to find out the major drivers of the industry and (...) identify the leadership style that may prove to be effective in the said industry. In the next phase of the study, a survey method approach was used where different tourism companies and hotel chains were included for analysis. The study aimed to check employee’s perception of change leadership and its impact on their resilience and ultimately the sustainable organization performance of companies’ operationalizing in the sector with moderating impact of sustainable tourism attitude in times of a crisis. In total, 430 full-time workers in the tourism industry were contacted for a self-administered survey achieving a response rate of 83%. The findings of the study confirmed that in the presence of a change leader, the process of adaptation to sudden changing situations amidst financial crises, pandemic, and climatic change, becomes bearable and employees can cope with the work situations without pushing them to quit the industry. The study has a significant contribution toward a rapidly growing and focused industry, which can play a major role in the economy of any country leading toward job creation and poverty reduction.

One distinguishing feature of vertebrate oocyte meiosis is its discontinuity; oocytes are released from their prophase I arrest, usually by hormonal stimulation, only to again halt at metaphase II, where they await fertilization. The product of the c‐mos proto‐oncogene, Mos, is a key regulator of this maturation process. Mos is a serine‐threonine kinase that activates and/or stabilizes maturation‐promoting factor (MPF), the master cell cycle switch, through a pathway that involves the mitogen‐activated protein kinase (MAPK) cascade. Oocytes arrested at prophase I (...) lack detectable levels of Mos, which must be synthesized from a pool of maternal mRNAs for proper maturation. While Mos is necessary throughout maturation in Xenopus, it seems to be required only for meiosis II in the mouse. The translational activation of c‐mos mRNA at specific times during meiosis requires cytoplasmic polyadenylation. Cis‐ and trans‐acting factors for polyadenylation are, therefore, essential elements of maturation. (shrink)

How do we know that what has happened to us is a microaggression? I claim in this chapter that our understanding about how we perceive microaggression is grounded in the cultivation and critical reflection about experiences of people who occupy marginalized social locations. My aim is to explore the nature of epistemic harms of microaggression in order to highlight how they diminish the microaggressed’s ability to generate and participate in making knowledge claims. I differentiate between the primary (direct) harm of (...) microaggressive acts, and the secondary epistemic harms that occur in the aftermath of the microaggression, particularly when the microaggressed attempts to convey their experience to others. I conclude with an analysis of the two secondary harms in hopes that it helps us explore a possible avenue of resistance to the epistemic harms of microaggression. (shrink)
