Objectives The objectives of the study are to understand the current practice of informed consent in medical research in public hospitals in Shanghai, and to share our views with other countries, especially developing countries. Methods In the study, 145 consent forms (CFs) of the selected research projects in eight public hospitals with ethics committees in Shanghai were audited, and the principle investigators (PIs) of these research projects and 40 student subjects who had participated in clinical drug tests were surveyed by (...) questionnaires. Results The CFs of medical researches in public hospitals with ethics committees in Shanghai were generally acceptable. However, there were some defects in the CFs. Although most of the surveyed PIs had correct recognition of informed consent, some processes of informed consent were not in accordance with generally accepted requirements. A large number of the PIs considered the greatest difficulty with informal consent was lack of correct recognition of subjects or legally authorised representatives on medical research. Discussion Informed consent in medical research should consider the research ethics, the background of potential subjects, the local resources and culture of medical research. In addition, special protection is needed for student subjects in informed consent as well as efforts for building and restoring the public's trust in biomedical research. Conclusion The informed consent in Shanghai's public hospitals with ethics committees was generally acceptable and the achievement of adequate informed consent is influenced by many factors.

This paper proposes the modified generalization of the HSS to solve a large and sparse continuous Sylvester equation, improving the efficiency and robustness. The analysis shows that the MGHSS converges to the unique solution of AX + XB = C unconditionally. We also propose an inexact variant of the MGHSS and prove its convergence under certain conditions. Numerical experiments verify the efficiency of the proposed methods.

This paper studies two dual notions in module theory—namely, radicals and socles—from the standpoint of reverse mathematics. We first consider radicals of Z-modules, where the radical of a Z-module M is defined as the intersection of pM={px:x∈M} with p taken from all primes. It shows that ACA0 is equivalent to the existence of radicals of Z-modules over RCA0. We then study socles of modules over commutative rings with identity. The socle of an R-module M is the largest semisimple submodule of (...) M. We show that the existence of socles of modules over a commutative ring with identity is equivalent to ACA0 over RCA0. Vector spaces are semisimple modules over fields. In general, semisimple modules possess nice properties of vector spaces. Lastly, we study characterizations of semisimple modules over commutative rings using techniques of reverse mathematics. (shrink)

What is the role of conscious experience in the epistemology of perceptual knowledge: how should we characterise what is going on in seeing that o is F in order to illuminate the contribution of seeing o to their status as cases of knowing that o is F? My proposal is that seeing o involves conscious acquaintance with o itself, the concrete worldly source of the truth that o is F, in a way that may make it evident to the subject (...) that o is an instance of ‘x is F’ as she understands this, and hence evident that o is F. Seeing that o is F is thus a way of its being evident that o is F and is therefore a way of knowing that o is F. (shrink)

Contrary to its self-proclamation, philosophy started not with wonder, but with time thrown out of joint. It started when the past has become a problem. Such was the historical situation facing Athens when Plato composed his Socratic dialogues. For the philosopher of fifth century BCE, both the immediate past and the past as the Homeric tradition handed down to the citizens had been turned into problematicity itself. In this essay, I will examine the use of philosophy as memory theatre in (...) Plato's Republic. I shall do so by interpreting Book X of the Republic as Plato's “odyssey” and suggest that such Platonic odyssey amounts to an attempt to re-inherit the collapsed spatial and temporal order of the fallen Athenian maritime empire. In my reading, the Odysseus in the Myth of Er comes forth for Plato as the exemplary Soldier-Citizen-Philosopher who must steer between the Scylla of ossified political principles and the whirling nihilism of devalued historical values, personified by Charybdis. I shall further suggest that Plato’s memory theatre also constitutes a device of amnesia and forgetting. The post-Iliadic Odysseus must drink of forgetfulness from the river Lethe, so that the revenant soldier, Er, and those who inherited the broken historical present during and after the Peloponnesian War, would be enabled to remember in a particular way. Such remembrance, I shall conclude, may be what Plato means by philosophy, a memory theatre of psychic regulation and moral economy that sets itself decidedly apart from earlier tragic and comic catharsis.

Cooper proved in [S.B. Cooper, Strong minimal covers for recursively enumerable degrees, Math. Logic Quart. 42 191–196] the existence of a c.e. degree with a strong minimal cover . So is the greastest c.e. degree below . Cooper and Yi pointed out in [S.B. Cooper, X. Yi, Isolated d.r.e. degrees, University of Leeds, Dept. of Pure Math., 1995. Preprint] that this strongly minimal cover cannot be d.c.e., and meanwhile, they proposed the notion of isolated degrees: a d.c.e. degree is isolated (...) by a c.e. degree if is the greatest c.e. degree below , and we also say that isolates . In [G. Wu, Bi-isolation in the d.c.e. degrees, J. Symbolic Logic 69 409–420], Wu extended Cooper–Yi’s notion and proved that there are intervals of d.c.e. degrees containing exactly one c.e. degree . Following Cooper and Yi’s notion, is called a bi-isolating degree. The bi-isolating degrees are dense in the high c.e. degrees. Arslanov asked whether the bi-isolating degrees occur in every jump class. In this paper, we prove that there are low bi-isolating degrees, providing a partial solution to Arslanov’s question.

Lachlan observed that the infimum of two r.e. degrees considered in the r.e. degrees coincides with the one considered in the ${\Delta_2^0}$ degrees. It is not true anymore for the d.r.e. degrees. Kaddah proved in (Ann Pure Appl Log 62(3):207–263, 1993) that there are d.r.e. degrees a, b, c and a 3-r.e. degree x such that a is the infimum of b, c in the d.r.e. degrees, but not in the 3-r.e. degrees, as a < x < b, c. In (...) this paper, we extend Kaddah’s result by showing that such a structural difference occurs densely in the r.e. degrees. Our result immediately implies that the isolated 3-r.e. degrees are dense in the r.e. degrees, which was first proved by LaForte. (shrink)

In order to obtain a new structure of beam flexure hinge with good performance, the flexure hinge based on the X-lattice structure is researched in this paper. The truss model in the finite element method is used to model the 6-DOF compliance of the flexure hinge based on the X-lattice structure. The influence of structural parameters on the compliance and compliance ratio of flexure hinges is analyzed based on this model, and the performance is compared with the traditional beam flexure (...) hinge of the same size. In order to design a flexure hinge based on the X-lattice structure with good comprehensive performance, this paper proposes an intelligent structure optimization method based on a genetic algorithm. The feasibility of the optimization algorithm is verified by an example. (shrink)

This paper considers the connection between automaticity, control and agency. Indeed, recent philosophical and psychological works play up the incompatibility of automaticity and agency. Specifically, there is a threat of automaticity, for automaticity eliminates agency. Such conclusions stem from a tension between two thoughts: that automaticity pervades agency and yet automaticity rules out control. I provide an analysis of the notions of automaticity and control that maintains a simple connection: automaticity entails the absence of control. An appropriate analysis, however, shows (...) that actions are forms of control and pervasively automatic even if automaticity implies the absence of control. Consequences are drawn for the theory of mental agency and the psychological concepts of automaticity and control. (shrink)

In this book, Xin Conan-Wu presents a radically revisionist analysis on Zhu Xi’s (1130–1200) Neo-Confucian philosophy of education. She argues that landscape and poems in twelfth-century academies bespeak his natural pedagogy and reveal unsuspected contributions to Chinese cultural sensibility by this emblematic figure of a stultifying orthodoxy.

Executive control of attention refers to processes that detect and resolve conflict among competing thoughts and actions. Despite the high-level nature of this faculty, the role of awareness in executive control of attention is not well understood. In this study, we used interocular suppression to mask the flankers in an arrow flanker task, in which the flankers and the target arrow were presented simultaneously in order to elicit executive control of attention. Participants were unable to detect the flanker arrows or (...) to reliably identify their direction when masked. There was a typical conflict effect (prolonged reaction time and increased error rate under flanker-target incongruent condition compared to congruent condition) when the flanker arrows were unmasked, while the conflict effect was absent when the flanker arrows were masked with interocular suppression. These results suggest that blocking awareness of competing stimuli with interocular suppression prevents the involvement of executive control of attention. (shrink)

This article compares the use of Romantic metaphor with the Chinese literary device xiang 象 (which I translate as “thing-metaphor”) in regard to how they embody different metaphysical relations between humans and things. Whereas Romantic metaphor transports a physical thing to the immaterial realm of imagination, xiang is a literary device in which the material qualities of the thing, while creatively interpreted to generate human meaning, retain ontologically a strong physical presence. Xiang therefore epitomizes a theory of creation that challenges (...) the Western dualistic paradigm: that the poet creates not virtual copies of the thing, but meanings of the thing, and therefore our relationships with things. The article concludes with Heidegger’s discourses on metaphor to suggest that my discussion of thing-metaphor has universal applicability. (shrink)

De-anthropocentrism is the leitmotif of philosophy in the twenty-first century, encouraging diverse and competing thoughts as to how this goal may be achieved. This article argues that the method by which we may achieve de-anthropocentrism is ethical rather than metaphysical – it must involve a creation of the self, rather than an interpretation of the given human conditions. Through engagements with the thought of Nietzsche, Levinas, and Foucault, and a close reading of Baudelaire’s poem “La Beauté,” I will illustrate three (...) ethical commitments essential to de-anthropocentrism: to abandon the claim to knowledge associated with human reason, to remain in perpetual quest of an object, and to transgress the given perceptual structure through aesthetic experience. In contrast to Kantian philosophy built upon universal human reason, art is the ethical arena where each artist creates their own way to relate to the object, while de-anthropocentrism occurs – this article argues – when the artist includes the self as the field of creation. Object-Oriented Ontology in my assessment is the only branch of philosophy that truly achieves de-anthropocentrism. (shrink)

EDITOR’S ABSTRACTThis article argues that Shang Yang’s philosophy of law was not only a means to enrich the state and strengthen its army, but also envisioned the orderly rule of all All-under-Heaven. Through a fair, universal, and reliable use of rewards, punishments, and also teaching, this vision of laws could ultimately lead to the promotion of moral values, popular consensus, and people’s self-governance. While the authors admit that in Shang Yang’s own historical context, law was no more than a tool (...) used by the ruler to suppress his people, potentially his ideas could contribute to a future Chinese society fully ruled by law and morality, and inspired by the rule of law.
