The increasing demand for horticultural products for nutritional and economic purposes by lesser developed countries (LDC's) is well-documented. Technological demands of the LDC's producing horticultural products is also increasing. Pesticide use is an integral component of most agricultural production, yet chemicals are often supplied without supplemental information vital for their safe and efficient implementation. Illiteracy rates in developing countries are high, making pesticide education even more challenging. For women, who perform a significant share of agricultural tasks, illiteracy rates are even (...) higher than for men. The dilemma exists of how a developing country can improve its nutritional and economic situation without giving consideration to social and environmental consequences. (shrink)

Which are major debates in environmental ethics and why is necessary to put upside down the traditional anthropocentric/non- anthropocentric debate? Ecocentric ethic is not an anti-human position, and it has to become the global ethic: it's not a matter of economics but it's the common good, in a Socratic sense.

BACKGROUND -/- The need for detailed description and modeling of cells drives the continuous generation of large and diverse datasets. Unfortunately, there exists no systematic and comprehensive way to organize these datasets and their information. CELDA (Cell: Expression, Localization, Development, Anatomy) is a novel ontology for the association of primary experimental data and derived knowledge to various types of cells of organisms. -/- RESULTS -/- CELDA is a structure that can help to categorize cell types based on species, anatomical localization, (...) subcellular structures, developmental stages and origin. It targets cells in vitro as well as in vivo. Instead of developing a novel ontology from scratch, we carefully designed CELDA in such a way that existing ontologies were integrated as much as possible, and only minimal extensions were performed to cover those classes and areas not present in any existing model. Currently, ten existing ontologies and models are linked to CELDA through the top-level ontology BioTop. Together with 15.439 newly created classes, CELDA contains more than 196.000 classes and 233.670 relationship axioms. CELDA is primarily used as a representational framework for modeling, analyzing and comparing cells within and across species in CellFinder, a web based data repository on cells (http://cellfinder.org). -/- CONCLUSIONS -/- CELDA can semantically link diverse types of information about cell types. It has been integrated within the research platform CellFinder, where it exemplarily relates cell types from liver and kidney during development on the one hand and anatomical locations in humans on the other, integrating information on all spatial and temporal stages. CELDA is available from the CellFinder website: http://cellfinder.org/about/ontology. (shrink)

There has been an ongoing debate about the best approach in environmental ethics. Bryan Norton believes that “weak anthropocentrism” will yield the best results for public policy, and that it is the most defensible position. In contrast, I have argued that an ecocentric, holistic position is required to deal with the urgent environmental problems that face us, and that position is complemented by the ecosystem approach and complex systems theory. I have called this approach “the ethics of integrity,” and in (...) this paper I show why this perspective suggests better solutions to difficult cases, for which “weak anthropocentrism” fails to provide an answer.

Some problems relating to the probabilistic description of a free particle and of a charged particle moving in an electromagnetic field are discussed. A critical analysis of the Klein-Gordon equation and of the Dirac equation is given. It is also shown that there is no connection between commutativity of operators for physical quantities and the existence of their joint probability. It is demonstrated that the Heisenberg uncertainty relation is not universal and explained why this is so. A universal uncertainty relation (...) for canonically conjugate coordinates and momenta is suggested. (shrink)

Rotations in Quantum Mechanics are a very well-known subject. When one is faced with rotations related to the SO group, for instance, all the underlying operators are well-known and built from their classical counterparts. However, when it comes to represent rotations related to the SU group, it is always argued that there is no classical counterpart from which the expressions for the quantum mechanical operators can be built. The approach is always done using matrix representation. In the way of this (...) aproach, one assumes that the operators related to SU are pseudovectors and end up with the weird result that only rotations by multiples of \ would bring the system to its original situation. In Olavo we have shown that any half-integral spin system can be represented in the Schrödinger picture by solving a Schrödinger equation with well defined expressions for the SU differential operators. It turned out that two of these operators are symmetric tensors, not pseudovectors or antisymmetric tensors. In this paper we use these results to dismiss with the \ conundrum. (shrink)

This study of three central themes in the logic of Alexander of Aphrodisias, the greatest of the ancient Aristotelian commentators, provides insight not only into Aristotle's logical writings but also into the tradition of scholarship which they spawned.

While open science gains prominence in South Africa with the encouragement of open data sharing for research purposes, there are stricter laws and regulations around privacy – and specifically the use, management and transfer of personal information – to consider. The Protection of Personal Information Act No. 4 of 2013 (POPIA), which came into effect in 2021, established stringent requirements for the processing of personal information and has changed the regulatory landscape for the transfer of personal information across South African (...) borders. At the same time, draft national policies on open science encourage wide accessibility to data and open data sharing in line with international best practice. As a result, the operation of research ethics committees (RECs) in South Africa is affected by the conflicting demands of the shift towards open science on the one hand, and the stricter laws protecting participants’ personal information and the transfer thereof, on the other. This article explores the continuing evolving role of RECs in the era of open data and recommends the development of a data transfer agreement (DTA) for the ethical management of personal health information, considering the challenges that RECs encounter, which centres predominantly on privacy, data sharing and access concerns following advances in genetic and genomic research and biobanking.

The author of the article discusses a political discourse of the US president Donald Trump. The political discourse is considered to be a type of discourse based on views and beliefs, the purpose of which is to manipulate the consciousness of the addressee using strategies in order to form certain beliefs. The strategy in this case means the plan of implementation of the communicative task, necessary for effective achievement of the addressee’s goal, realized with the help of certain tactics. The (...) choice of the subject matter is determined by the interest to political communication. The author analyses discourse strategies and markers, stylistic and lexico-grammatical means used as manipulative means in Donald Trump’s Acceptance Speech, Victory Speech, and Inaugural Address. Special attention is given to the strategy of improvement, strategy of enhancement, and strategy for evaluation of alternatives. It is known that presidential public addresses are of great importance, therefore communicative skills of politicians and ability to speak in public play a great role in their political career. The analysis of D. Trump’s presidential discourse has revealed the use of discursive manipulative strategies and manipulative markers, numerous repetitions, calls for joint action, the use of ‘unifying vocabulary‘, slogans, inversion. It is noted that the presidential political discourse is an effective means of manipulating the consciousness of the nation and the formation of its outlook. The author concludes that speech manipulation is a complex phenomenon, the effectiveness of which depends on linguistic, psychological, extralinguistic, and social factors. (shrink)

The article deals with the role of public addresses delivered by the US first lady Michelle Obama in forming the presidential image. Special attention is paid to communicative strategies, stylistic and lexico-grammatical means used in public addresses for influencing the electorate. It is shown that both Obama and his spouse’s speeches play an important role in the electorate consciousness manipulation in the USA.

It is shown that no concrete particle can have zero rest mass. A separate photon is proven to be a concrete particle. The nonexistence of the electromagnetic field as an independent physical reality is demonstrated. The existence of a subatomic electromagnetic particle of a very small rest mass, theemon, instead of the electromagnetic field, is stated. The compatibility of the notion of the emon with the special relativity theory is elucidated. Some corollaries of the existence of the emon as well (...) as the possibilities of determining its rest mass are discussed. The explanations of the relativity aberration and Doppler effect in terms of the emon are given. The importance of the principle of concreteness of experiments is emphasized and illustrated. Some related problems are noticed. (shrink)

Brian Skyrms (1987, 1990, 1993, 1997) has discussed the role of dynamic coherence arguments in the theory of personal or subjective probability. In particular, Skryms (1997) both reviews and discusses the utility of martingale arguments in establishing the convergence of beliefs within the context of radical probabilism. The classical martingale converence theorem, however, assumes the countable additivity of the underlying probability measure; an assumption rejected by some subjectivists such as Bruno de Finetti (see, e.g., de Finetti 1930 and 1972). This (...) brief note has a very modest goal: to briefly consider the extent to which Skyrms’s argument can be extended to the finitely additive case. (shrink)

The man in the street to-day is aware that recent developments in the physical sciences have necessitated a fundamental revision of the concepts of physics; he finds that Einstein is no less upsetting to his ideas than was Copernicus to those of his own time or than Darwin was to Bishop Wilberforce. The plain man who has “ philosophical leanings ” is aware that questions previously regarded as metaphysical—and about which philosophers have written much that is unintelligible—are now recognized as (...) falling within the scope of physics. Every reader of this Journal is aware that the criticism to which the main concepts of physics—space, time, matter—have been subjected is so fundamental that it is no longer possible to say that there are material bodies in space, which have events happening to them at a given time. We must substitute the conception of a fourfold continuum within which space, time and matter are inextricably involved. Finally, we are told that this new way of regarding the classical trinity suggests the consequence that we know nothing about the “ inner nature ” of the terms with which we deal, we can make no assertions as to the ultimate nature of that to which they may refer. In this respect the prevailing temper of the present-day scientist is to be contrasted with the cocksureness of most nineteenth-century physicists l who, even if they did not go so far as to say “ we know what matter is,” at least suggested that only the metaphysician had, or could have, any doubts as to its nature and reality^.

By exploring the hypothesis of magnetic monopoles, we consider the existence of electric fields produced by magnetic current densities. Then, we consider a uniformly rotating frame with the purpose of searching for effects of rotation on the interaction of axial electric fields with the magnetic quadrupole moment of a neutral particle. Our analysis is made through the WKB approximation. Therefore, by applying the WKB approximation, we search for bound state solutions to the Schrödinger equation in two particular cases.
