维吾尔族与汉族的大学生在汉语歧义词消解中的语境促进效应及反应抑制效应

词汇歧义是语言的普遍现象。在汉语中, 歧义词的种类繁多, 是少数民族学生汉语学习困难的重要原因之一。通过两个实验, 考察在不同加工时间条件下维吾尔族和汉族的大学生在汉语歧义词消解中的语境促进效应及抑制效应。结果发现, 两个民族的大学生均出现了语境促进效应, 但在短时加工条件下, 汉族大学生的语境促进效应显著大于维吾尔族大学生, 在长时加工条件下, 两个民族的大学生的语境促进效应并无显著差异。在短时加工条件下, 仅汉族大学生可以有效地抑制无关信息的干扰; 在长时加工条件下, 两个民族的大学生均可以有效地抑制无关信息的干扰。整个研究表明, 在汉语歧义词消解中, 随着加工时间增加, 维吾尔族大学生的语境促进效应和对无关信息的抑制均可以达到与汉族大学生相近的水平。     

A hypothesis on the rhythm of becoming

An archetype of rhythms is set forth which tries to explain, simply and coherently, the quantum discontinuities which take place both in the evolutionary dynamics of the Macrocosmos—universal history—and in the Microcosmos—individual development.

The stationary waves and musical theory give us the key to understand those quantum leaps in the vibrating processes of unfurling and furling between the Nothing and the Whole: the successive 2nd harmonics (1/3) are generating sonorous novelties. This simple scheme fits, with surprising accuracy, all the basic bifurcations that paleontologists, anthropologists, historians and psychologists speak to us about.

It seems to be confirmed then that an emerging hierarchy of order could characterize the processes of the universe. Evolution would then be the temporal unfurling (‘explicate order“) of those intrinsic levels of potential stability of the non‐dual reality (‘implicate order“).     

The Holographic Principle of Mind and the Evolution of Consciousness

The Holographic Principle holds that the information in any region of space and time exists on the surface of that region. Layers of the holographic, universal “now” go from the inception of the universe to the present. Universal Consciousness is the timeless source of actuality and mentality. Information is experience, and the expansion of the “now” leads to higher and higher orders of experience in the Universe, with various levels of consciousness emerging from experience. The brain consists of a nested hierarchy of surfaces that range from the most elementary field through the neuron, neural group, and the whole brain. Evidence from the evolution and structure of the brain shows that optimal surface areas in a variety of structures are conserved with respect to underlying surfaces. Microgenesis, the becoming of the mental state through a process of recapitulation of development and evolution, is in full accord with the Holographic Principle. Evidence from a wide variety of contexts indicates the capacity on the mind for total recall of past life events and for access to universal information, indicating connection with the holographic surfaces of prior “nows” and with the Universal holographic boundary. In summation, the Holographic Principle can help us explain the unity and mechanisms of perception, experience, memory, and consciousness.     

An ordered arrangement of atom columnar clusters in a pentagonal quasiperiodic lattice of an Al-Ni-Co decagonal quasicrystal

The structure of an Al-Ni-Co decagonal quasicrystal (called the S1-type superstructure), which shows diffraction patterns with superlattice reflections, has been studied by atomic-scale observations of electron microscopy. The structure of the decagonal quasicrystal can be characterized as an ordered arrangement of two kinds of atom columnar cluster with different directions of pentagonal symmetry. A fundamental lattice, which is constructed by connecting all the atom clusters, shows a pentagonal quasiperiodic lattice with a bond length of about 2 nm. The pentagonal lattice is divided into two superlattices, which are constructed by connecting atom clusters with the same directions of pentagonal symmetry, with a bond length of 2     

Hume's Experimental Method

In this article I attempt to reconstruct David Hume's use of the label ‘experimental’ to characterise his method in the Treatise. Although its meaning may strike the present-day reader as unusual, such a reconstruction is possible from the background of eighteenth-century practices and concepts of natural inquiry. As I argue, Hume's inquiries into human nature are experimental not primarily because of the way the empirical data he uses are produced, but because of the way those data are theoretically processed. He seems to follow a method of analysis and synthesis quite similar to the one advertised in Newton's Opticks, which profoundly influenced eighteenth-century natural and moral philosophy. This method brings him much closer to the methods of qualitative, chemical investigations than to mechanical approaches to both nature and human nature.     

THE SUPERNATURAL AS LANGUAGE GAME

Abstract. For many in the Anglo‐American tradition of language analysis, Ludwig Wittgenstein, the great progenitor of twentieth‐century philosophy of language, showed conclusively that theological terms lack any referent in reality and therefore represent a discourse that can do no more than manifest the existential attitudes that speakers take toward reality as a whole. To think that such terms represent more is to be bewitched by the use of language. Is it possible, however, that theological language references a fundamental human drive? In this article I reexamine the dyad of nature and supernature from the perspective of Wittgenstein's philosophy. Perhaps surprisingly, Wittgenstein's thought on the subject offers much more than his famous, terse aphorism at the conclusion of his first masterwork, the Tractatus Logico‐Philosophicus ([1921] 1961, 74, §7): “What we cannot speak about we must pass over in silence.” Furthermore, the basic Tractarian drive to determine the relationship between language and reality, which is redirected but not extinguished in Wittgenstein's second, divergent, opus, the Philosophical Investigations ([1953] 1967), may be the place for a renewed examination of what the supernatural means in human discourse. Does talk of God give expression to the fundamental transcendence of human knowledge? Is it a language game we can eschew?

Inhibition of PKA anchoring to A-kinase anchoring proteins impairs consolidation and facilitates extinction of contextual fear memories

Both genetic and pharmacological studies demonstrated that contextual fear conditioning is critically regulated by cyclic AMP-dependent protein kinase (PKA). Since PKA is a broad range protein kinase, a mechanism for confining its activity is required. It has been shown that intracellular spatial compartmentalization of PKA signaling is mediated by A-kinase anchoring proteins (AKAPs). Here, we investigated the role of PKA anchoring to AKAPs in different stages of the memory process (acquisition, consolidation, retrieval and extinction) using contextual fear conditioning, a hippocampus-dependent learning task. Mice were injected intracerebroventricularly or intrahippocampally with the membrane permeable PKA anchoring disrupting peptides St-Ht31 or St-superAKAP-IS at different time points during the memory process. Blocking PKA anchoring to AKAPs resulted in an impairment of fear memory consolidation. Moreover, disrupted PKA anchoring promoted contextual fear extinction in the mouse hippocampus. We conclude that the temporal and spatial compartmentalization of hippocampal PKA signaling pathways, as achieved by anchoring of PKA to AKAPs, is specifically instrumental in long-term contextual fear memory consolidation and extinction, but not in acquisition and retrieval.
