Martial wrote about himself and his participation in the everyday life of Rome more than any other extant poet of the post-Augustan Principate. More particularly, dozens of his epigrams describe the life of the ordinary client and his treatment by great and often arrogant patrons. Unfortunately for social and literary historians, however, Martial was writing satirical epigrams, not autobiography. Consequently, his poetry cannot be taken at face value as a direct reflection of Roman life. With regard to literary patronage, the (...) difficulties of interpretation have allowed modern scholars to reach diametrically opposed conclusions. One editor and commentator baldly labelled Martial ‘a chronic beggar’ who ‘despite his numerous friends and the many patroni to whom he paid court,…dragged on a hand-to-mouth existence’. In a recent and more detailed study, on the other hand, Martial is portrayed as a man of independent means, who looked to his powerful amici not for financial support so much as for help in publicizing his work and for protection in literary squabbles.

Este artigo recorda os principais aspectos e motivações da Expedição Langsdorff, missão de reconhecimento do interior do Brasil iniciada em 1821, composta pelo cônsul russo barão Langsdorff, o pintor alemão Moritz Rugendas, Aimé-Adrien Taunay, Nicolas-Antoine Taunay, o polígrafo Hercules Florence e o especialista em mapas Néster G. Rubtsov. Busca diferenças entre esta expedição e iniciativas outras, a título de exemplo, as dos bandeirantes e jesuítas, bem como a expedição indigenista de Rondon, e propõe o aprofundamento das investiga­ções. Apresenta atributos resgatados (...) pela poesia brasileira contemporânea e elementos cons­titutivos da identidade cultural brasileira presentes na Expedição Langsdorff, os quais os auto­res sugerem ser relevantes para pesquisadores do tema e para a inserção do Brasil no contexto internacional político, diplomático e econômico nos tempos hodiernos.

Interactive technology assessment (iTA) provides an answer to the ethical problem of normative bias in evaluation research. This normative bias develops when relevant perspectives on the evaluand (the thing being evaluated) are neglected. In iTA this bias is overcome by incorporating different perspectives into the assessment. As a consequence, justification of decisions based on the assessment is provided by stakeholders having achieved agreement. In this article, agreement is identified with wide reflective equilibrium to show that it indeed has the potential (...) of justifying decisions. We work out several conditions for this agreement to be achievable and just. (shrink)

Error is protean, ubiquitous and crucial in scientific process. In this paper it is argued that understanding scientific process requires what is currently absent: an adaptable, context-sensitive functional role for error in science that naturally harnesses error identification and avoidance to positive, success-driven, science. This paper develops a new account of scientific process of this sort, error and success driving Self-Directed Anticipative Learning (SDAL) cycling, using a recent re-analysis of ape-language research as test example. The example shows the limitations of (...) other accounts of error, in particular Mayo’s (Error and the growth of experimental knowledge, 1996) error-statistical approach, and SDAL cycling shows how they can be fruitfully contextualised.

To whom do sperm and ova belong? Few tissues are produced by the human body with more waste than the germ cells. Yet dominion over the germ cells, and over the early embryo that results from their union in vitro, is behind much of the emotion that modern reproductive intervention can engender. The germ cells differ from other human tissues that can be donated or transplanted because they carry readily utilizable genetic information. Eventual expression of the germ cells' genetic potential (...) is the legitimate concern and responsibility of their donors, although in the right circumstances the responsibility can by agreement be entrusted to institutions administering gamete or embryo donor programmes; these institutions, in turn, may need to assume responsibility for decisions if, in the case of embryo storage, the wishes of the two donors conflict. The fact of sperm and ovum ownership (and the genetic potential that goes with it) before individuals part with these tissues is beyond dispute. Some contentious issues may be clarified if this area of human dominion, namely control over genetic expression among offspring, is acknowledged to be the legitimate persisting concern of those who have produced sperm and ova after storage commences.

The 1973 archeological discovery of important documents of classical thought known as the Huang-Lao Boshu coupled with advancements in contemporary jurisprudence make possible a reassessment of the philosophies of pre-Qin and early Han China. This study attempts to elucidate the importance of the Huang-Lao school within the intellectual tradition of China through a comparison of the Boshu's philosophical position, particularly its understanding of the relation between law and morality, with the respective views of major thinkers of the period--Confucius, Han Fei, (...) Lao Zi, Zhuang Zi, and to a lesser extent, Shen Dao, Shen Buhai and the authors of the Guan Zi and He Guan Zi. So doing reveals Huang-Lao to be a unique and sophisticated social and political philosophy which, until its expulsion from court by Emperor Wu and subsequent adoption by Daoist religion, served as the ideological foundation for the post-Qin reforms of the early Han.

Many physicists regard the flow of time as an illusion. There is an upper level flow of time, the phenomenon of past/present/future; and there is a lower level flow of time which is really a flow of events. Perceptual completion accounts for the lower level flow of time in a few ways: apparent movement; amodal completion; and dynamic change as exemplified by a newly described modal completion that we called happening. It acts like an illusory percept connecting discrete stimuli in (...) all sensory modalities. The past/present/future distinction cannot exist unless an object is perceived to be the same now as it is then. This cognition requires object persistence. Experiments with object persistence suggest the circumstances when that, too, is an illusory percept. The illusory percepts of object persistence and perceptual completion can account for the entire flow of time. Our findings and conclusions are congruent with a few time theories and cosmologies that suggest that the flow of time is an illusion. (shrink)

According to the causal interpretation of quantum mechanics, one can precisely define the state of an individual particle in a many-body system by its position, momentum, and spin. It is shown in the EPR spin experiment that the quantum torque brings about an instantaneous change in the state of one of the particles when the other undergoes a local interaction, but that such a transfer of “information” cannot be extracted by any experiment subject to the laws of quantum mechanics.

I propose that neural cognition is supported by non-neural storage of a 3-D model of local space, used in the planning of movements. Information is stored in wave-like excitations which couple to neurons in the thalamus, with the wave-vectors of excitations representing spatial positions. This hybrid of neural and non-neural cognition may have fitness advantages over any purely neural mechanism -- in information capacity, geometric accuracy, and fast selective retrieval. The wave excitations may be sustained on a Bose-condensed state of (...) some excitation in the brain, by a mechanism like those investigated by Frohlich, Umezawa, Vitiello and others. These states, being frictionless, can store information indefinitely at low energy levels, insulated from thermal noise, so are an ideal substrate for memory. If a Bose-condensed state is a 3-D representation of local reality, it may be the basis of phenomenal consciousness . The resulting theory of consciousness is highly constrained, and agrees well with the main properties of conscious experience. In this account, consciousness arises from a very simple state of matter, rather than from complexity; and it evolved to meet one of the strongest selection pressures on the brain. (shrink)

Human societies are extraordinarily cooperative compared to those of most other animals. In the vast majority of species, individuals live solitary lives, meeting to only to mate and, sometimes, raise their young. In social species, cooperation is limited to relatives and (maybe) small groups of reciprocators. After a brief period of maternal support, individuals acquire virtually all of the food that they eat. There is little division of labor, no trade, and no large scale conflict. Communication is limited to a (...) small repertoire of self-verifying signals. No one cares for the sick, or feeds the hungry or disabled. The strong take from the weak without fear of sanctions by third parties. Amend Hobbes to account for nepotism, and his picture of the state of nature is not so far off for most other animals. In contrast, people in even the simplest human societies regularly cooperate with many unrelated individuals. Human language allows low-cost honest communication of virtually unlimited complexity. The sick are cared for, and sharing leads to substantial flows of food from the middle aged to the young and old. Division of labor and trade are prominent features of every historically known human society, and archaeology indicates that they have a long history. Violent conflict among sizable groups is common. In every human society, social life is regulated by commonly held moral systems that specify the rights and duties of individuals enforced, albeit imperfectly, by third party sanctions. (shrink)

The primary aim of this article is to reveal a number of previously unrecorded appearances of classical Latin poetry in the poems of Ausonius, with a brief assessment of their value in understanding his text, and an incorporation of them into the general picture of his acquaintance with his predecessors; a final section will outline some ways in which his adoptions and adaptations are used. Latin poets now fragmented or lost are not included in this study; for the survival of (...) a Lucilius or an Ennius has generally enjoyed more attention and study than the after-life of better-known authors. It is moreover doubtful if such early writers had a context to offer the borrower in Late Antiquity; while poets of the second and third centuries A.D. , who did, are poorly known today. (shrink)

The integration of a Responsible Research and Innovation (RRI) approach to food systems can contribute to redirect research and innovation toward the Sustainable Development Goal (SDG) 2 - Zero hunger - as well as other intertwined SDGs. Even though the scientific literature bridging RRI and food systems has grown over the past years, no critical reviews of this scholarship are currently available. This paper fills this gap by producing a critical review of the scientific literature on RRI in food systems (...) that has been published between 2017 and 2023. Our search led to a selection of 47 research articles that were analysed for this review. Our findings show that studies in this scholarship have focused on the stages of inputs/agricultural production, with a focus on digital technologies for agriculture. When analysing the motivations for applying RRI, we found that this varied from reasons that are more market-related, such as increasing technologies’ societal acceptance, to a reorientation of food systems towards the tackling of societal challenges. Concerning the conceptualization of RRI in food systems, we found that scholars relied on a widely known definition, but its interpretation varied greatly among the studies. Finally, we analysed how RRI has been applied in this literature and found that while some scholars provided examples of responsible innovation, others applied it to analyse innovation governance, and others used RRI to analyze research projects or innovations to ‘improve’ their alignment with this concept. Overall, this literature review showed that there is a need to develop more collaborative and reflexive work to unlock RRI’s potential to inform policy and practice that can foster more responsive and inclusive food systems capable of achieving SDG2.

An attempt has been made in this paper to trace Gandhi's principle of 'nonviolence' in the context of 'Enlightenment Rationality' on the one hand and 'Globalization' on the other. The ideas of freedom/independence, autonomy, sovereignty, property, maturity/adulthood, public and private, tolerance, scientific rationality, secularism, humanism, democracy, nation/ state, universality of moral actions, humanity as an end in itself, critique of religion, etc., are the most operative terms of European Enlightenment of the 19th century. Though these ideas evolved and developed in (...) Europe, yet they proliferated beyond Europe to other continents and subcontinents. Gandhi appreciated these ideas and like a genius, he interpreted them into indigenous concepts and principles such as truth, simplicity, faith, brahmacharya, purushartha, satyagraha, swaraj, karma, compassion, trusteeship, vegetarianism/fruitarianism and above all nonviolence with the aim of attaining swaraj - victory over one's passions, lusts, greed, etc., and independence and sovereignty of the country. I may point out, though I shall not be in a position to develop it here, that the basic concepts of the Enlightenment were questioned and repudiated by Marx, Engels and Lenin on the one hand and the critical theorists like Adorno, Horkheimer, Marcuse and Habermas on the other. In the era of globalization, the Enlightenment concepts have become almost obsolete. But Gandhi's principles are still valid. These are the only viable principles to resolve moral dilemmas that everybody faces, being constantly confronted by equally valid alternatives in globalization. Hence I'll propose a modest critique of the Enlightenment and the globalization from Gandhi's perspective of nonviolence. (shrink)

We introduce a linear analogue of Läuchli's semantics for intuitionistic logic. In fact, our result is a strengthening of Läuchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on functorial polymorphism, consists of dinatural transformations which are equivariant with respect to all such actions. Such dinatural transformations are called uniform. To any sequent in Multiplicative Linear Logic (...) , we associate a vector space of“diadditive” uniform transformations. We then show that this space is generated by denotations of cut-free proofs of the sequent in the theory MLL + MIX. Thus we obtain a full completeness theorem in the sense of Abramsky and Jagadeesan, although our result differs from theirs in the use of dinatural transformations.As corollaries, we show that these dinatural transformations compose, and obtain a conservativity result: diadditive dinatural transformations which are uniform with respect to actions of the additive group of integers are also uniform with respect to the actions of arbitrary cocommutative Hopf algebras. Finally, we discuss several possible extensions of this work to noncommutative logic.It is well known that the intuitionistic version of Läuchli's semantics is a special case of the theory of logical relations, due to Plotkin and Statman. Thus, our work can also be viewed as a first step towards developing a theory of logical relations for linear logic and concurrency. (shrink)
