Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

The issue of COVID-19 vaccine allocation is still highly controversial on the international as well as on the national level, and policy-makers worldwide struggle in striking a fair balance between different ethical principles of vaccine allocation, in particular maximum benefit, reciprocity, social justice and equal respect. Any political decision that implements these principles comes at a cost in terms of loss of lives and of loss of life years that could potentially have been prevented by a different vaccination strategy. This (...) article illustrates these trade-offs using quantitative analysis and shows how this approach can contribute to providing a rational and transparent grounding of political decisions on COVID-19 vaccine allocation.

The present paper addresses Molnar’s problem :72–86, 2000): that of finding positive truthmakers for negative truths. The proposed solution, called, is to hold truth and falsity to be primitive and positive features of propositions and to take every literal negative truth to be made true by the falsity of the atomic proposition that it embeds. The solution is shown to be compatible with Maximalism, Necessitarianism and with the Entailment Thesis, as well as with most if not all possible variants (...) of truthmaking theory. Other advantages of are noted: it doesn’t require the inclusion of exotic objects in one’s ontology; it doesn’t require any revision of one’s logic or of one’s theory of modality. The solution also allows one to eschew negative facts, tropes and properties while providing a definition of negativity for certain literal propositions. The paper ends by rebutting several objections that may be levelled against. (shrink)

George Molnar came to see that the solution to a number of the problems of contemporary philosophy lay in the development of an alternative to Hume's metaphysics. This alternative would have real causal powers at its centre. Molnar set about developing a thorough account of powers that might persuade those who remained, perhaps unknowingly, in the grip of Humean assumptions. He succeeded in producing something both highly focused and at the same time wide-ranging. He showed both that the (...) notion of a power was central and that it could serve to dispel a number of long-standing philosophical problems.Molnar's account of powers is as realist as any that has so far appeared. He shows that dispositions are as real as any other properties. Specifically, they do not depend for their existence on their manifestations. Nevertheless, they are directed towards such manifestations. Molnar thus appropriates the notion of intentionality, from Brentano, and argues that it is the essential characteristic of powers. He offers a persuasive case for there being some basic and ungrounded powers, thus ruling out the reducibility of the dispositional to the non-dispositional. However, he does allow that there are non-power properties as well as power properties. In this respect, his final position is dualistic.This is contemporary metaphysics of the highest quality. It is a work that was almost complete when its author died. It has been edited for publication by another specialist in the subject, Stephen Mumford, who has also provided an introduction that will allow non-specialists to become acquainted with the issues. David Armstrong, one of the greatest living metaphysicians and personal friend of George Molnar, has provided a Foreword. (shrink)

In this book, T. L. Short places the notorious difficulties of Peirce's important writings in a more productive light, arguing that he wrote philosophy as a scientist, by framing conjectures intended to be refined or superseded in the inquiries they initiate. He argues also that Peirce held that the methods and metaphysics of modern science are amended as inquiry progresses, making metaphysics a branch of empirical knowledge. Additionally, Short shows that Peirce's scientific work expanded empiricism on empirical grounds, grounding his (...) phenomenology and subverting the fact/value dichotomy, and that he understood statistical explanations in nineteenth-century science as reintroducing the idea of final causation, now made empirical. Those innovations underlie Peirce's late ideas of a normative science and of philosophy as a branch of science. Short's rich and original study shows us how to read Peirce's writings and why they are worth reading. (shrink)

U clanku autori ispituju tri pozicije u estetickoj raspravi o uzvisenom koja se vodila u 18. veku - Edmunda Berka, Imanuela Kanta i Fridriha Silera. Oni takodje pokusavaju da rekonstruisu politicku pozadinu svake od ovih teorijskih pozicija: starorezimski konzervativizam, republikanski liberalizam i romanticarsku zudnju za 'trecim putem'. Najsofisticiraniju i najzreliju teoriju uzvisenog pronalaze u Silerovim estetickim delima, pogotovo u onima koja su usledila nakon njegovog razocarenja u Francusku revoluciju i u kojima su najtemeljnije razmatrani odnosi izmedju uzvisenog i paradoksa istorijskog (...) nasilja.

In this article the authors are reconstructing the dichotomies which the young Theodor Adorno was trying to detect in the music of the bourgeois epoch and personify in two antipodes - Franz Schubert and Ludwig van Beethoven. Although already a devotee of Arnold Sch?nberg and the 20th century music avantgardism, Adorno was, in his works prior to his exile from Germany, intensively dealing with Schubert and his opposition towards Beethoven. While Beethoven was a bold and progressive revolutionary, fascinated by the?practical (...) reason? and the mission to rise up and reach the stars, Schubert wanted none of it. Instead, he was looking backwards, to primordial nature and the possibility of man to participate in its mythic cycles of death and regeneration. The lack of synthesis between this two opposing tendencies in the music of early bourgeois epoch lead to the?negative dialectics? of Sch?nberg and 20th century music avantgardism and to the final separation of Beethovenian musical progress and Schubertian musical mimesis.

Autorka u clanku rekonstruise kompleksnu sliku Franca Suberta koju je stvorio Teodor Adorno u nekoliko osvrta na ovog kompozitora, a najvise u clanku?Subert? iz 1928. Adorno je te, 1928. godine doziveo Suberta kao tragicnog kompozitora cija muzika obitava u oblasti htonskih bogova, a da ipak otkriva radost?putujuceg naroda, opsenara i cudotvoraca?. Ipak, nije objasnio kako ova radost moze da prezivi u paklenim pejsazima Subertove htonske muzike. Tek kasnije Adorno je bio spreman da u Subertu prepozna, zahvaljujuci njegovom?habitusu?, i kafanskog sviraca, (...) ne pominjuci vise?putujuci narod, opsenare i cudotvorce?. Te dve predstave Suberta-Subert kao osluskivac htonskih bogova i Subert kao kafanski svirac-pokazale su se kao zanimljiv par vredan dalje teorijske elaboracije koju Adorno, nazalost, nikada nije sproveo.

The research described in this paper was designed to identify the factors that influence the importance small-scale farmers place on different marketing channels of short food supply chains. The focus concerns two entirely different types of market that are present in the bigger cities in Hungary: ‘conventional’ markets where there are no restrictions on locality but the farmer-market relationship is based on binding contracts, and newly-emergent farmers’ markets at which only local growers can sell ad hoc, using their own portable (...) facilities. Results are based on a survey that was conducted in 2013 among 156 Hungarian market oriented farmer-vendors at different types of market and confirm that different markets are visited by different types of farmers. Farmers who favour conventional markets are typically less educated, operate on smaller scales and are more committed to their chosen markets via long-term contracts. The preference for farmers’ markets is stronger with farmers who are more open to cooperation, have specific investment plans for developing their farms and among those who are specifically looking to directly interact with their customers to avoid middlemen. The relevance of the findings is highlighted by the ongoing Short Food Supply Chain Thematic Sub-programme in the present European Union financing period; farmers’ profiles in any given marketing channel must be understood if short food supply chains are to be effectively promoted. Different types of small-scale farmers will benefit from different supporting frameworks, interventions, and initiatives. (shrink)

Purpose of the article is to present the way of application of methodology of environmental metrics within the total environmental assessment framework. An inevitable part of sustainable development initiatives is sustainable measurement metrics. This kind of metrics is being represented by three sets of indicators: Environmental, Social and Economic. Sustainability measurement metrics tends to measure environmental safety, social responsibility and economic efficiency. Studying behaviour of companies in sustainability measurement metrics application, using another scientific method is well welcomed. Methods used in (...) article are synthesis, analysis, deduction and comparative analysis. We are synthesizing those methods in a presented model which examines quality of environmental improvements across departments of selected organization. In other words, the model is able to quantify an extent how individual managerial decision contributed towards overall improvement in environmental performance of whole organization. Model works with and additive elements. In order to derive results using multiplicative elements, we are using logarithmic method in a model. Scientific aim of the article is to synthesize scientific methods aimed at environmental performance measurement into unified and universal model usable by managements of small and medium-sized enterprises. The background of this mission is to ensure that environmental performance will be correctly reported, data delivered by various companies will be benchmarkable and consequently, Corporate Social Responsibility concepts worked out by individual organizations will be trustable. In the article, we are discovering that use of proposed universal model has marketable outcomes. Thanks to an existence of thriving markets valuating triple bottom line of sustainability, results delivered by the model helped to a company PintInox, S. p. A. to succeed at such kind of market. Conclusions the article delivers are pointing out an importance of interdisciplinary cooperation within field of sustainable development. (shrink)

As COVID-19 emerged as a phenomenon of the total environment, and despite the intertwined and complex relationships that make humanity an organic part of the Bio- and Geospheres, the majority of our responses to it have been corrective in character, with few or no consideration for unintended consequences which bring about further vulnerability to unanticipated global events. Tackling COVID-19 entails a systemic and precautionary approach to human-nature relations, which we frame as regaining diversity in the Geo-, Bio-, and Anthropospheres. Its (...) implementation requires nothing short of an overhaul in the way we interact with and build knowledge from natural and social environments. Hence, we discuss the urgency of shifting from current to precautionary approaches to COVID-19 and look, through the lens of diversity, at the anticipated benefits in four systems crucially affecting and affected by the pandemic: health, land, knowledge and innovation. Our reflections offer a glimpse of the sort of changes needed, from pursuing planetary health and creating more harmonious forms of land use to providing a multi-level platform for other ways of knowing/understanding and turning innovation into a source of global public goods. These exemplary initiatives introduce and solidify systemic thinking in policymaking and move priorities from reaction-based strategies to precautionary frameworks. (shrink)

There has been a plethora of studies outlying the various factors which may affect undergraduate student cheating, generally focusing on individual, situational and deterrent factors. But beyond these factors, does the type of cheating affect students’ perceptions of cheating? We found that there were differences in regards to gradable cheating such as cheating on homework, tests and papers versus non-gradable cheating such as illegally downloading software/music from the Internet or photocopying materials which violate the university’s academic integrity policy. Gender, discussion (...) of ethical issues in class and enforcement of cheating reduces the acceptance of cheating across types of cheating. Less time spent on the Internet reduces the acceptance of only non-gradable cheating and the type of institution and knowing the consequences of cheating reduces the acceptance of only gradable cheating.

In this paper we introduce the modelwise interpolation property of a logic that states that whenever \(\models\phi\to\psi\) holds for two formulas \(\phi\) and \(\psi\), then for every model \(\mathfrak{M}\) there is an interpolant formula \(\chi\) formulated in the intersection of the vocabularies of \(\phi\) and \(\psi\), such that \(\mathfrak{M}\models\phi\to\chi\) and \(\mathfrak{M}\models\chi\to\psi\), that is, the interpolant formula in Craig interpolation may vary from model to model. We compare the modelwise interpolation property with the standard Craig interpolation and with the local interpolation (...) property by discussing examples, most notably the finite variable fragments of first order logic, and difference logic. As an application we connect the modelwise interpolation property with the local Beth definability, and we prove that the modelwise interpolation property of an algebraizable logic can be characterized by a weak form of the superamalgamation property of the class of algebras corresponding to the models of the logic.

New numerical solutions of 3+1D covariant kinetic theory are reported for nuclear collisions in the energy domain Ecm∼200 AGeV. They were obtained using the MPC 0.1.2 parton transport code employing high parton subdivision to retain Lorentz covariance. The solutions are compared to those of relativistic hydrodynamics employing Cooper–Frye isotherm freeze-out. The transport solutions follow a different dynamical path than hydrodynamics due to large dissipative effects when pQCD scattering rates and HIJING initial conditions are assumed. The transport freeze-out four-volume is sensitive (...) to the reaction rates. The final transverse momentum distributions are found to deviate by up to an order of magnitude from those of Cooper–Frye frozen hydrodynamics. (shrink)

Do undergraduate students perceive that it is more acceptable to ‹cheat’ using information technology (IT) than it is to cheat without the use of IT? Do business discipline-related majors cheat more than non-business discipline-related majors? Do undergraduate students perceive it to be more acceptable for them personally to cheat than for others to cheat? Questionnaires were administered to undergraduate students at five geographical academic locations in the spring, 2006 and fall 2006 and spring, 2007. A total of 708 usable questionnaires (...) were returned including 532 from students majoring in business-related disciplines and 139 from students majoring in non-business related disciplines (37 were undecided). It appears that in terms of intellectual property violations, undergraduate students in general find cheating using IT more acceptable than cheating without the use of IT. It also appears that undergraduate students perceive that it is relatively more acceptable for them to personally cheat when using IT than for others to cheat when using IT, although this is reversed when IT is not involved. No significant differences on these issues were found between undergraduate students having business discipline-related majors and those having non-business discipline-related majors. (shrink)

Students from a small, private, religious college and a large, public university completed questionnaires asking their perceptions of academic dishonesty at their institution. The questionnaires used a 5-point Likert scale to determine whether the students felt it was acceptable to cheat for a specific reason such as plagiarizing or copying homework both using and not using technology. Between fall 2005 and fall 2013, 1792 usable questionnaires were collected using similar methodology, questionnaires and respondents to control for possible extraneous variables. An (...) analysis of the data provides indications that student acceptance of many types of academic dishonesty has decreased over the past 9 years. (shrink)
