Apotemnophilia is a condition that causes those who have it to not feel “correct” in their own bodies. As a result, an intense obsession develops with removing the limb; this obsession hinders tremendously the patients' social behaviour and societal integration. These patients, in some respects resembling transgendered individuals, feel that the body part (limb) in question is simply “not a part of themselves”, causing them to feel uncomfortable in their own bodies. Whether amputations should be performed on apotemnophiles or not (...) is a question that poses a significant medical ethical dilemma. It is argued that observing an apotemnophile's request for amputation is the ethical action. The major arguments opposing such amputations and supporting such amputations are examined and critically analysed with regard to ethical principles—namely, patient autonomy, beneficence, non-maleficence and justice with regard to every person's “right to happiness”. Finally, a discourse on how the accepted notion of harm does not apply to apotemnophilia is developed to justify the position that amputation is indeed medically the ethical choice. (shrink)

Radical reflection is the philosophical and scientific exercise in answering the original question of human sciences. Starting from his criticism of scientific objectivism, Calvin O. Schrag points out his thesis that by radicalization of knowledge and values in human experiences, human sciences can develop its own rationality which couples with the technical methodological reason. This article will delve with Schrag’s concept of radical reflection in human sciences in three sections: the first section is dealing with Schrag’s appreciation of Husserl’s critique (...) of the ideals of objectivism, the second discusses the development of radical reflection, and the third focuses on the ontological implication of radical reflection that it guides us to understand of daily life experiences. The article concludes that since radical reflection focuses on the original experience, its rationality must be counted on by its technical methodological reason and the metaphorical reason.

Scientific discovery is an important moment in scientific pursuit, but only a few philosophers of science appreciate this moment as a logical issue. Starting from his understanding that all thought contains components of which we are subsidiarily aware in focal content of thinking, Michael Polanyi puts out his thesis that scientific discovery cannot be justified by a series of strictly explicit operations but by merely invoking deeper forms of commitment in sighting the problem and the vision of reality. This article (...) will delve into Polanyi’s notion of scientific discovery in three sections: the first section is dealing with Polanyi’s concept of heuristic philosophy which tones that discovery of problem is the primary requisite of a good scientist to vision reality, the second discusses the role of intellectual passions in scientific justification, and the third focuses on the ontological implication of scientific discovery that it guides us to comprehension of something real both tangible and intangible. The article concludes that since scientific discovery involves the creative and imaginative appeal to reality, its rationality must be counted on by its logical structure and personal experiences in scientific community.

The paper presents an approach to encrypt the color images using bit-level permutation and alternate logistic map. The proposed method initially segregates the color image into red, green, and blue channels, transposes the segregated channels from the pixel-plane to bit-plane, and scrambles the bit-plane matrix using Arnold cat map (ACM). Finally, the red, blue, and green channels of the scrambled image are confused and diffused by applying alternate logistic map that uses a four-dimensional Lorenz system to generate a pseudorandom number (...) sequence for the three channels. The parameters of ACM are generated with the help of Logistic-Sine map and Logistic-Tent map. The intensity values of scrambled pixels are altered by Tent-Sine map. One-dimensional and two-dimensional logistic maps are used for alternate logistic map implementation. The performance and security parameters histogram, correlation distribution, correlation coefficient, entropy, number of pixel change rate, and unified averaged changed intensity are computed to show the potential of the proposed encryption technique.
