Recent scientific and technological developments have promoted the emergence of biobanks on a population scale. Although the storage of human biological material has taken place for a long time, it is only recently that biobanks have acquired a broader scientific significance, especially for genomic research. The increase in biobanks creates many ethical dilemmas, such as the protection of privacy, and creates the need for a new regulatory framework, which must enable the sustainable development of biobanks while also protecting the rights (...) of research subjects and biobank participants.

Die Debatten zu den Themen Physikalismus, Willensfreiheit und Künstliche Intelligenz stehen seit einigen Jahren im Mittelpunkt der Philosophie des Geistes. In den Debatten um den Physikalismus geht es dabei u.a. um folgende Fragen: Lässt sich alles, was es gibt, physikalisch erklären - auch der menschliche Geist? Lässt sich alles auf das Physische reduzieren? Ist der Bereich des Physischen kausal geschlossen? Realisiert das Physische das Mentale? Wie lässt sich mentale Verursachung erklären? In den Debatten um Willensfreiheit fragt man sich: Sind wir (...) physikalisch determiniert? Können wir freie Entscheidungen treffen? Sind wir für unsere Handlungen verantwortlich? Wie verhalten sich Freiheit und Determinismus zueinander? Welchen Beitrag kann die empirische Forschung leisten? In den Debatten um Künstliche Intelligenz werden diese Fragen verhandelt: Können Maschinen denken? Unterscheiden sich Menschen von Maschinen? Sind uns Computer geistig überlegen? Stellt maschinelle Intelligenz ein Modell für menschliche Kognition dar? Welchen wissenschaftlichen Nutzen kann Künstliche Intelligenz haben? Zu jedem der drei Themen Physikalismus, Willensfreiheit und Künstliche Intelligenz bietet das Buch drei Originalbeiträge von renommierten Wissenschaftlern verschiedener Disziplinen sowie jeweils einen kritischen Kommentar. Auf diese Weise soll deutlich werden, dass die drei Themen nicht nur eng miteinander zusammenhängen, sondern auch interdisziplinär von großem Interesse sind. (shrink)

The notion of a weak Messianic power serves as the focal point for this study of theological, materialist, poetic, and post-Freudian psychoanalytic approaches to time and the historical unconscious in the work of Benjamin, Celan and Derrida.

In the case of magnetic resonance imaging (MRI) imaging, image processing is crucial. In the medical industry, MRI images are commonly used to analyze and diagnose tumor growth in the body. A number of successful brain tumor identification and classification procedures have been developed by various experts. Existing approaches face a number of obstacles, including detection time, accuracy, and tumor size. Early detection of brain tumors improves options for treatment and patient survival rates. Manually segmenting brain tumors from a significant (...) number of MRI data for brain tumor diagnosis is a tough and time-consuming task. Automatic image segmentation of brain tumors is required. The objective of this study is to evaluate the degree of accuracy and simplify the medical picture segmentation procedure used to identify the type of brain tumor from MRI results. Additionally, this work suggests a novel method for identifying brain malignancies utilizing the Bagging Ensemble with K-Nearest Neighbor (BKNN) in order to raise the KNN’s accuracy and quality rate. For image segmentation, a U-Net architecture is utilized first, followed by a bagging-based k-NN prediction algorithm for classification. The goal of employing U-Net is to improve the accuracy and uniformity of parameter distribution in the layers. Each decision tree is fitted on a little different training dataset during classification, and the bagged decision trees are effective since each tree has minor differences and generates slightly different skilled predictions. The overall classification accuracy was up to 97.7 percent, confirming the efficiency of the suggested strategy for distinguishing normal and pathological tissues from brain MR images; this is greater than the methods that are already in use.

“Free riding,” used as a descriptive term, refers to taking a jointly produced benefit without contributing towards its production. Used as a term of criticism, it refers to the wrongful failure to contribute towards the joint production of benefits that one receives. On either usage, the central interest of moral philosophy in free riding is the same: to specify the conditions under which not contributing towards the joint production of benefits that one receives is wrong, and to explain why.

There is a strong need to connect agricultural research to social movements and community-based food system reform efforts. Participatory research methods are a powerful tool, increasingly used to give voice to communities overlooked by academia or marginalized in the broader food system. Plant breeding, as a field of research and practice, is uniquely well-suited to participatory project designs, since the basic process of observing and selecting plants for desirable traits is accessible to participants without formal plant breeding training. The challenge (...) for plant breeders engaged in participatory research is to consider not only how their work incorporates farmer input in developing new varieties, but also how it interacts with broader questions of food sovereignty, food justice, diversity and democratization in the food system. This article examines these issues in the context of the Seed to Kitchen Collaborative, a participatory variety evaluation and breeding project at the University of Wisconsin-Madison. (shrink)

COVID-19 has stolen millions of lives and devastated livelihoods around the world and led to the exacerbation of existing inequities within and between countries. This part of a tragic pattern in catastrophes, where the most vulnerable populations are typically the ones to bear the greatest burdens. Jecker and Au1 offer a keen observation of how one particular COVID-19 response—Zero COVID—appears particularly problematic from a health equity perspective. Under Zero COVID, countries enact stringent lockdowns and movement restrictions in order to keep (...) cases as low as possible. Yet such restrictive policies hurt disadvantaged populations the most, by severely curtailing their ability to earn a living and forcing them to remain in cramped living spaces for potentially extended periods of time. However, the link between Zero COVID and health inequity is more complex than it might at first appear. This is because Zero COVID is itself compatible with meaningful efforts to mitigate inequities, including those caused by Zero COVID policies themselves. Conversely, certain inequities seemingly characterised by Zero COVID may persist even when Zero COVID is abandoned, indicating their ultimate root and …. (shrink)

The problems of this passage were concisely stated by M. Platnauer more than thirty years ago and his suggestions for their solution have been adopted and developed in A. S. F. Gow's magnum opus. Its authority—so the present writer suspects—is liable at this point to eclipse the meaning of the text.

The conceptual framework of behaviorism is reconstructed in a logical scheme rather than along chronological lines. The resulting reconstruction is faithful to the history of behaviorism and yet meets the contemporary challenges arising from cognitive science, psycholinguistics, and philosophy. In this reconstruction, the fundamental premise is that psychology is to be a natural science, and the major corollaries are that psychology is to be objective and empirical. To a great extent, the reconstruction of behaviorism is an elaboration of behaviorist views (...) of what it is for a science to be objective and empirical. The reconstruction examines and evaluates behaviorist positions on observation and the rejection of introspection, the behavioral data language, theory construction, stimulus-response psychology, the organization of behavior, complex processes, agency, and the interpretation of mentalistic language. The resulting reconstruction shows behaviorism to be a pragmatic psychological version of positivism based on a behavioral epistemology. (shrink)

Although nature of science and nature of scientific inquiry are related to each other, they are differentiated as NOS is being more related to the product of scientific inquiry which is scientific knowledge whereas NOSI is more related to the process of SI. Lederman et al. determined eight NOSI aspects for K-16 context. In this study, a science camp was conducted to teach scientific inquiry and NOSI to 24 6th and 7th graders. The core of the program was guided inquiry (...) in nature. The children working in small groups under guidance of science advisors conducted four guided-inquiries in the nature in morning sessions on nearby plants, animals, water, and soil. NOSI aspects were made explicit during and at the end of each inquiry session. Views about scientific inquiry questionnaire was applied as pre- and post-test. The results of the study showed that children developed in all eight NOSI aspects, but higher developments were observed in “scientific investigations all begin with a question” and “there is no single scientific method,” and “explanations are developed from data and what is already known” aspects. It was concluded that the science camp program was effective in teaching NOSI. (shrink)

The King Report on Corporate Governance (1994) evoked unprecedented interest in corporate governance in South Africa. This does not mean that corporate governance was not an issue of concern before the release of this historical report. To the contrary, corporate governance in its broader sense has been at stake since the inception of the first publicly owned companies in South Africa. This article intends to give an overview of corporate governance in South Africa. It starts by making a distinction between (...) broad and narrow conceptions of corporate governance. Before applying this distinction to the practice of corporate governance in South Africa, a brief overview of the corporate landscape in South Africa is provided. Then the South African situation with regard to broad and narrow corporate governance respectively is analysed. The article ends with a discussion of the review of corporate governance that currently is in the making in South Africa. Throughout the article both the financial and ethical dimensions of corporate governance is attended to. (shrink)

Open peer commentary on the article “A Cybernetic Computational Model for Learning and Skill Acquisition” by Bernard Scott & Abhinav Bansal. Upshot: The paper is an admirable example of first-order cybernetics. It does not appear to be developed as part of the constructivist paradigm and of second-order cybernetics. It neglects research as the context that generates problems of observation.

A geometric formulation of the gravitation theory in the spacetime R × S 3 is given. A linear connection is introduced on the tangent bundle T(R × S 3 ) and then the connection coefficients and the Riemann curvature tensor are calculated. It is shown that their expressions differ from those of Carmeli and Malin [Found. Phys.17, 407 (1987)] by supplementary terms due to the noncommutativity of derivatives used on the spacetime R × S 3 . The Einstein field equations (...) are written as usually and a comparison with other results is given. Finally, some observations about a possible gauge theory of gravitation in the spacetime R × S 3 are made. (shrink)

A model for gauge theories over a compact Lie group is described using R × S3 as background space. The U(1) and SU(2) gauge theories are considered as particular examples, and a comparison with other results is given. Our results differ from those of Carmeli and MalinFound. Phys. 16, 791 (1986);17, 193 (1987)] by a supplementary term in the curvature tensor due to the noncommutativity of derivatives used on R × S3 space. Some observations about supersymmetry and gravity on R (...) × S3 space are also given. (shrink)

In the article "The Epistemological Nature of Information Modeling" [Gnoseologicheskaia priroda informatsionnogo modelirovaniia], Voprosy filosofii, 1963, No. 10, Academician V. M. Glushkov examines two important methodological aspects of the modeling of natural objects and phenomena in the contemporary natural sciences. The first consists of the informational nature of the models created, and the second of their dynamism. The dynamic nature of today's models in the natural sciences means that it is not so much the material structure of the object that (...) is modeled as its behavior and functions in some sphere of natural phenomena. In this sense, the models under examination may also be termed functional, as distinct from the structural models pertaining to a static description of objects. (shrink)
