Automatic detection of diseases and anatomical landmarks in medical images by the use of computers is important and considered a challenging process that could help medical diagnosis and reduce the cost and time of investigational procedures and refine health care systems all over the world. Recently, gastrointestinal (GI) tract disease diagnosis through endoscopic image classification is an active research area in the biomedical field. Several GI tract disease classification methods based on image processing and machine learning techniques have been proposed (...) by diverse research groups in the recent past. However, yet effective and comprehensive deep ensemble neural network-based classification model with high accuracy classification results is not available in the literature. In this thesis, we review ways and mechanisms to use deep learning techniques to research on multi-disease computer-aided detection about gastrointestinal and identify these images. We re-trained five state-of-the-art neural network architectures, VGG16, ResNet, MobileNet, Inception-v3, and Xception on the Kvasir dataset to classify eight categories that include an anatomical landmark (pylorus, z-line, cecum), a diseased state (esophagitis, ulcerative colitis, polyps), or a medical procedure (dyed lifted polyps, dyed resection margins) in the Gastrointestinal Tract. Our models have showed results with a promising accuracy which is a remarkable performance with respect to the state-of-the-art approaches. The resulting accuracies achieved using VGG, ResNet, MobileNet, Inception-v3, and Xception were 98.3%, 92.3%, 97.6%, 90% and 98.2%, respectively. As it appears, the most accurate result has been achieved when retraining VGG16 and Xception neural networks with accuracy reache to 98% due to its high performance on training on ImageNet dataset and internal structure that support classification problems.

In his account of the Persian Wars, the 5th century historian Herodotus reports an exchange between the Persian monarch Xerxes and a deposed Spartan king, Demaratus, who became what Lattimore later classified as a “tragic warner” to Xerxes. On the eve of the battle of Thermopylae, Xerxes asks how a small number of free Spartiates can stand up against the massive ranks of soldiers that Xerxes has assembled. Herodotus has Demaratus reply: So is it with the Lacedaemonians; fighting singly they (...) are as brave as any man living, and together they are the best warriors on earth. Free they are, yet not wholly free; for law is their master (ἐλεύθεροι γὰρ ἐόντες οὐ πάντα ἐλεύθεροι εἰσί· ἔπεστι γάρ σφι δεσπότης νόμος), whom they fear much more than your men fear you. This is my proof—what their law bids them, that they do; and its bidding is ever the same, that they must never flee from the battle before whatsoever odds, but abide at their post and there conquer or die. (Hdt. 7.104) As the outcome of Thermopylae makes clear, Demaratus is hardly guilty of boasting. But Greek political theorists were not only fascinated by the Spartans who fought at the battle of Thermopylae in 480; they also wondered how slightly more than a century later Sparta was ignobly defeated by Thebes at the battle of Leuctra in 371, after which Spartan hegemony collapsed. How did Sparta field citizen-soldiers in the 5th century who were without parallel in their bravery and military prowess? And why did Sparta, predominantly under the same political organization, collapse just over a century later? Such are the main questions that Xenophon, Plato, Aristotle, and Plutarch—what Cartledge (1999, 313–14) has characterized as “political-theoretical” laconophiles—seek to answer in their writings about Sparta.

In this paper I focus on the figure of the ape in Nietzsche's texts, and how it fits into his putative naturalism. I examine the lowly status and ignoble qualities that he associates with this animal and argue that they betray a residual anthropocentricism profoundly at odds with Nietzsche's dehumanized conception of nature. Accordingly, I suggest a reading of Nietzsche's ape remarks that brings them more into accord with his non-teleological and non-hierarchical conception of species. Ultimately, I argue that (...) a robust, thorough going Nietzschean naturalism would require the affirmation of the ape, including everything it comes to represent for Nietzsche. (shrink)

Mill defines utilitarianism as the combination of a “theory of life” and a moral claim: only pleasure and freedom from pain are desirable as ends, and the promotion of happiness is the sole goal of moral action. So defined, utilitarianism is open to ad hominem pessimistic objection: a “theory of life” which entails the impossibility of happiness fits poorly with a morality centered on its promotion. The first two challenges Mill confronts in Utilitarianism share this pessimistic structure. Interestingly, however, these (...) challenges paint inverted pictures of the best utilitarian life: one suggests this life is satisfying but ignoble, the other that it is noble but unsatisfying. I explain Mill's treatment of both challenges as genuinely pessimistic interpretations of utilitarianism's “theory of life.” Read through the lens of Mill's engagement with pessimism, these challenges point to distinctive conceptions of dignity and satisfaction that play a significant role in Mill's ethics.

Early Confucian “moral psychology” developed in the context of undoing reactive emotions in order to promote relationships of reciprocal recognition. Early Confucian texts diagnose the pervasiveness of reactive emotions under specific social conditions and respond with the ethical-psychological mandate to counter them in self-cultivation. Undoing negative affects is a basic element of becoming ethically noble, while the ignoble person is fixated on limited self-interested concerns and feelings of being unrecognized. Western ethical theory typically accepts equality and symmetry as conditions (...) of disentangling resentment; yet this task requires the asymmetrical recognition of others. Confucian ethics integrates a nuanced and realistic moral psychology with the normatively oriented project of self-cultivation necessary for dismantling complex negative emotions in promoting a condition of humane benevolence that is oriented toward others and achieved through self-cultivation.

This paper examines Hobbes’s criticisms of Robert Boyle’s air-pump experiments in light of Hobbes’s account in _De Corpore_ and _De Homine_ of the relationship of natural philosophy to geometry. I argue that Hobbes’s criticisms rely upon his understanding of what counts as “true physics.” Instead of seeing Hobbes as defending natural philosophy as “a causal enterprise … [that] as such, secured total and irrevocable assent,” 1 I argue that, in his disagreement with Boyle, Hobbes relied upon his understanding of natural (...) philosophy as a mixed mathematical science. In a mixed mathematical science one can mix facts from experience with causal principles borrowed from geometry. Hobbes’s harsh criticisms of Boyle’s philosophy, especially in the _Dialogus Physicus, sive De natura aeris_, should thus be understood as Hobbes advancing his view of the proper relationship of natural philosophy to geometry in terms of mixing principles from geometry with facts from experience. Understood in this light, Hobbes need not be taken to reject or diminish the importance of experiment/experience; nor should Hobbes’s criticisms in _Dialogus Physicus_ be understood as rejecting experimenting as ignoble and not befitting a philosopher. Instead, Hobbes’s viewpoint is that experiment/experience must be understood within its proper place – it establishes the ‘that’ for a mixed mathematical science explanation. (shrink)

Unjustifiable assumptions about sex and gender roles, the untamable potency of maleness, and gynophobic notions about women's bodies inform and influence a broad range of policy-making institutions in this society. In December 2004, the U.S. Court of Appeals for the Sixth Circuit continued this ignoble cultural pastime when they decided Everson v. Michigan Department of Corrections. In this decision, the Everson Court accepted the Michigan Department of Correction's claim that “the very manhood” of male prison guards both threatens the (...) safety of female inmates and violates the women's “special sense of privacy in their genitals” and declared that sex-specific employment policies for prison guards is not impermissibly discriminatory. I believe that the Court's decision relies on unacceptable stereotypes about sex, gender and sexuality and it significantly undermines Title VII's power to end discriminatory employment practices.

Célèbre fourmi-homme E.O. Wilson a toujours été l’un de mes héros - non seulement un biologiste exceptionnel, mais l’une des minorités minuscules et en voie de disparition des intellectuels qui ose au moins faire allusion à la vérité sur notre nature que d’autres ne parviennent pas à saisir, ou dans la mesure osant o saisir, soigneusement éviter pour l’opportunisme politique. Malheureusement, il met fin à sa longue carrière d’une manière très sordide en tant que parti à une attaque ignorante et (...) arrogante sur la science motivée au moins en partie par la ferveur religieuse de ses collègues de Harvard. Il montre les conséquences ignobles lorsque les universités acceptent l’argent de groupes religieux, les revues scientifiques sont tellement impressionnés par les grands noms qu’ils évitent l’examen par les pairs appropriés, et quand les egos sont autorisés à devenir hors de contrôle. Il nous entraîne dans la nature de l’évolution, les bases de la méthodologie scientifique, comment les mathématiques se rapportent à la science, ce qui constitue une théorie, et même quelles attitudes à la religion et la générosité sont appropriées que nous approchons inexorablement l’effondrement de la civilisation industrielle.
