Contextual Cognitive Theory (CCT) is the latest teaching and learning theory in west countries, which reveals the nature of knowledge in a new perspective as well as the conditions of meaningful learning. The concept based on CCT corresponds to the principles proposed by the new curriculum standard for English. Therefore, it has great implications for the reform of English teaching in the classroom. In this paper, the author gives a brief account of the main points of CCT, and then, she discusses its pedagogical implications for the construction of new teaching strategies in the classroom through designing and analyzing teaching cases. 展开更多

Utilizing the acoustic emission(AE) technique, an experimental investigation into the damage evolution for steel strand under axial tension was described. The damage evolution model for steel stand relating the damage evolution to acoustic emission parameters was proposed by incorporating the AE rate process theory. The AE monitoring results indicate that damages occur in both elastic and plastic phases of steel strand. In elastic phase, AE signals are mainly sent out from the micro damage due to the surface friction among the wires of steel strand, while in plastic phase, AE signals emitted from the plastic deformation of wires. In addition, the AE cumulative parameters curves closely resemble the loading curve. The AE cumulative parameters curves can well describe the damage evolution process including the damage occurrence and damage development for steel strands. It is concluded that the AE technique is an effective and useful nondestructive technique for evaluating the damage characteristics of steel strand. 展开更多

The dynamic adsorption of possible intermediates on single-atom catalysts(SACs)under working condition plays a key role in the electrocatalytic performance by the oxygen evolution reaction(OER),and therefore the performance of the dynamic adsorption should be fully considered in the theoretical screening of potential SACs.Based on density functional theory calculations,the OER performance of 27 types of C_(2)N-supported single transition metal atoms(TM@C_(2)N)is systematically investigated without and with considering the dynamic adsorption of possible intermediates.Without considering dynamic adsorption,only Rh@C_(2)N and Ni@C_(2)N are screened out as good catalysts.However,by further considering the dynamic adsorption configurations of possible intermediates,more promising TM@C_(2)N SACs including Fe(Co,Ni,Ru,Rh,Ir)@C_(2)N toward the OER are screened out.The presence of the intermediates(*HO,*O)on SACs could shift their d band center toward lower energy level,which makes the interaction between the adsorbate and SACs moderate and thus enhances their OER performance.The present work is instructive for further screening and designing of efficient single-atom catalysts for the oxygen evolution reaction. 展开更多

Photoelectrochemical hydrogen evolution reaction(HER)is taken into account as an alternative to effective hydrogen production,emphasizing the importance of catalysts.The magnetism of catalysts could modulate the adsorption of the H atom and further enhance the HER activity.Herein,doping the double transition metal atoms on SnS_(2) nanosheet(TM_(2)@SnS_(2))to form the efficient magnetic catalyst is proposed to explore the spin magnetic effect on the HER performance.By performing first-principles calculations,nonmagnetic V_(2)@SnS_(2) is proved to be the candidate of the HER catalyst;nevertheless,the HER activities of antiferromagnetic and ferromagnetic V_(2)@SnS_(2) are relatively inferior due to the spin-induced charge redistribution.Meanwhile,machine learning analysis shows the absolute importance of the electronic structure of TM dopants and surrounding S ligands,and the HER activity could be predicted by the modified band centers of S-3p_(z) and TM-d.Furthermore,the proof-of-concept experiment has substantiated the above theoretical predictions by significantly increasing liner sweep voltammetry and photocurrent with applied magnetic field.This work provides a new avenue for uncovering the spin catalytic mechanism and the exploration and design of efficient HER catalysts. 展开更多

Despite almost half a century of research for theory of mind, its evolutionary origin is largely unknown. This paper proposes that the evolutionary origin of theory of mind starts from the beginning of the human evolution to form hominins through bipedalism and the mixed habitat. The feet of the early hominins were still adapted for grasping trees rather than walking for long distances and running fast on the ground. The early hominins lived in the mixed habitat of grassy woodland with patches of denser forest, and freshwater springs. The difficulty of walking in the mixed habitat leads to division of labor for the home specialist group (small children, old people, and mothers with small children, and pregnant women) in the safe forest area and the exploration specialist group (young people without the care of small children) in the dangerous open area. The different tasks, attitudes, and mentalities in different specialist groups produce theory of mind as the ability to attribute different mental states to different specialist groups. (Uniformity of mind instead of theory of mind is for generalists without division of labor). The early Homo species with the open habitat developed theory of mind for hunter specialist group and gatherer specialist group. The middle Homo species with complex stone tools developed theory of mind for the cooperative specialist groups in the large production of complex stone tools. The late Homo species with complex social interaction developed theory of mind for mind reading to enhance cooperation and to detect cheaters in complex social interaction. For religion, the unusually harsh Upper Paleolithic Period developed theory of mind for imaginary specialists in terms of supernatural power, guidance, and comfort. Therefore, the three general types of theory of mind are for specialists in division of labor, mind reading in complex social interaction, and imaginary specialists in imaginary division of labor under harsh conditions. Self-awareness in the mirror self-recognition test is also explained. 展开更多

In The Structure of Scientific Revolutions, Kuhn claimed that theory choice is a conversion experience and depends upon the personality or psychology of the individual scientist making the choice. Critics charged Kuhn with an irrational and a relativistic position concerning theory choice, arguing he advocated a subjective instead of an objective approach to how scientists choose one theory over another and thereby undercut epistemic accounts for the generation of scientific knowledge. In response to critics Kuhn insisted that his approach, although subjective, was still rational in that the criteria----vomposed of epistemic values--determining theory choice operate both objectively and subjectively. Recent work in cognitive neuropsychology, particularly in the dual-process theory of cognition, supports Kuhn's notion of theory choice. In this paper, I initially discuss Kuhn's approach to theory choice, along with criticism of it and his response to the criticism, followed by an examination of the dual-process theory of cognition. I then explore the application of dual-process theory to Kuhn's notion of theory choice, especially in terms of a historical case study from the biomedical sciences. I finally discuss briefly the implications of the dual-process theory for contemporary philosophy of science. 展开更多

It is generally cousidered that the mantle creep-flow eurtent is the most important internal cause for erustobody evolution. In fact, the Cause, mantle creep-now current takes place just beneath erustobody. Aeeording to the principle that internal causes of a tning determine its development and evolution, a special attetion should be paid to the basic causea of crustobody evolution. Vnder the guidance of the unbalanced self-organization theory, the authors elueidate that the crustobody system is a far-away thermal balaneed system and an open system, and thete are nonlinear interactions between the essentials, positive feedbacks and frequent fluetuation in the erustobody system. Finally, the following conelusions are drawn: the nonlinear interactions in the erustobody system are the basic formation (main internal cause) for erustobody evolution ; Substance and energy gained from surroundings are the basic conditions (main external cause) of crustobody evolution;and the fluctuations theide the erustobody system are the direct induetive cause of its evolution. 展开更多

One of the aims of controlled portion of violence to the community members. If the portions are too small then uncontrolled violence appears in different forms of criminality and self-destruction. In countries without virtual violence the terrorism and "suicide" bombers are born. For the male the aim of violence is a feeling of victory. In the nature only the winner has the right to reproduction. In a civilized society each male has the right to reproduction and the necessity to feel himself as a winner. Survival means right for reproduction. Civilization has turned the bite between men into a kiss between men (men winner) and women (men defeated), the kick between men--into a caress between men (men winner) and women (men defeated) and, finally, the violence between men into love/eros between men (men winner) and women (men vanquished) and violence between men into homosexuality/eros between men winner and men vanquished. In the civilization, the male is winner and the female simulates the defeated male, homo or animals. We can define eros as a substitute of violence in civilization like the metamorphose of violence. 展开更多

This paper modifies the Farnes’ unifying theory of dark energy and dark matter which are negative-mass, created continuously from the negative-mass universe in the positive-negative mass universe pair. The first modification explains that observed dark energy is 68.6%, greater than 50% for the symmetrical positive-negative mass universe pair. This paper starts with the proposed positive-negative-mass 11D universe pair (without kinetic energy) which is transformed into the positive-negative mass 10D universe pair and the external dual gravities as in the Randall-Sundrum model, resulting in the four equal and separate universes consisting of the positive-mass 10D universe, the positive-mass massive external gravity, the negative-mass 10D universe and the negative-mass massive external gravity. The positive-mass 10D universe is transformed into 4D universe (home universe) with kinetic energy through the inflation and the Big Bang to create positive-mass dark matter which is five times of positive-mass baryonic matter. The other three universes without kinetic energy oscillate between 10D and 10D through 4D, resulting in the hidden universes when D > 4 and dark energy when D = 4, which is created continuously to our 4D home universe with the maximum dark energy = 3/4 = 75%. In the second modification to explain dark matter in the CMB, dark matter initially is not repulsive. The condensed baryonic gas at the critical surface density induces dark matter repulsive force to transform dark matter in the region into repulsive dark matter repulsing one another. The calculated percentages of dark energy, dark matter, and baryonic matter are 68.6 (as an input from the observation), 26 and 5.2, respectively, in agreement with observed 68.6, 26.5 and 4.9, respectively, and dark energy started in 4.33 billion years ago in agreement with the observed 4.71 <span style="white-space:nowrap;">&plusmn;</span> 0.98 billion years ago. In conclusion, the modified Farnes’ unifying theory reinterprets the Farnes’ equations, and is a unifying theory of dark energy, dark matter, and baryonic matter in the positive-negative mass universe pair. The unifying theory explains protogalaxy and galaxy evolutions in agreement with the observations. 展开更多

Embodied cognition is an approach to cognition that departs from traditional Descartes’ mind-body dualism for its emphasis on bodily interactions with the environment. The paper firstly describes three distinctive features of embodied cognition. Furthermore, from the perspective of philosophical methodology, the paper outlines Vygotsky’s socio-cultural theory and his contributions to the development of cognitive science. Three basic themes of Vygotsky’s writings are specifically described: genetic forces as a foundation of the study of mind, social origin of higher mental functioning, and mediation of sign systems in inter-mental and intra-mental functioning. Against the background of Vygotsky’s sociocultural theory, we further discuss the interface between embodied cognition and Vygotsky’s socio-cultural theory. It is claimed that bodily states and body-environment interactions are closely connected to sense-making. Embodied cognition should emphasize on the unity of body, mind, and cultural environment. Finally, the paper concludes with the influence of sociocultural theory on the study of embodied cognition. 展开更多

The generative operations concerning the transformation between the active and the passive convert successively from PS rules, T-rules, D-structure, NP preposing and postposing, X-bar analysis, to case theory, government, checking theory and head movement. The development of the passive construct mirrors the trend of the progress of Chomskyan theory, evolving from the rule motivations to the principle motivations. The giant leap between the phases of the generative grammar has aroused great curiosity among the scholars and learners of syntax. In this paper, the author will explore the tacit strategy underlying the module changes of TG from the perspective of cognitive science. 展开更多

Nonequilibrium statistical theory of fracture is a theory of fracture that macromechanical quantities can be derived from the microscopic atomic mechanism of microcrack(or microvoid)evolution kinetcs by means of nonequilibrium statistical physical concepts and methods. The microcrack evolution equation is the central equation in the theory.The coefficents of the equation, the microcrack growth rate and the microcrack nucleation rate,come from microscopic atomic mechanism.The solution of the equation connects with macromechanical quantities by the model of the weakest chain. All the other formulas and quantities, for instance, distribution function,fracture probability, reliability, failure rate and macromechanical quantities such as strength, toughness, life etc. and their statistical distribution function and statistical fluctuation are derived in a unified fashion and expressed by a few physical parameters. This theory can be widely applied to various kinds of fracture, such as the brittle, fatigue, delayed and environmental fracture of metals and structural ceramics. The theoretical framework of this theory is given in this paper. 展开更多

AIM:To characterize the two components of theory of mind(ToM) in patients with esophageal cancer combined with depression.METHODS:Sixty-five patients with esophageal cancer combined with depression(depressed group) and 62 normal controls(control group) were assessed using reading the mind in the eyes test,faux pas task,verbal fluency test,digit span test and WAIS IQ test.The depressed group was divided into two subgroups including psychotic depressed(PD) group(32 cases) and nonpsychotic depressed(NPD) group(33 cases).The clinical symptoms of patients were assessed using Beck depression inventory version Ⅱ and brief psychiatric reacting scale(BPRS).RESULTS:There was a significant difference between the depressed group and the control group on tasks involving ToM social perceptual components(mind reading:t = 7.39,P < 0.01) and tests involving ToM social cognitive components(faux pas questions:t = 13.75,P < 0.01),respectively.A significant difference was also found among the PD group,the NPD group and the control group on mind reading(F = 32.98,P < 0.01) and faux pas questions(χ 2 = 78.15,P < 0.01),respectively.The PD group and NPD group performed worse than normal group controls both on mind reading and faux pas questions(P < 0.05).The PD group performed significantly worse than the NPD group on tasks involving ToM(mind reading:F = 18.99,P < 0.01;faux pas questions:F = 36.01,P < 0.01).In the depressed group,there was a negative correlation between ToM performances and BPRS total score(mind reading:r =-0.35,P < 0.01;faux pas questions:r =-0.51,P < 0.01),and between ToM performances and hostile suspiciousness factor score(mind reading:r =-0.75,P < 0.01;faux pas questions:r =-0.73,P < 0.01),respectively.CONCLUSION:The two components of ToM are both impaired in patients with esophageal cancer combined with depression.This indicates that there may be an association between ToM deficits and psychotic symptoms in clinical depression. 展开更多

This paper addresses the power con- trol problems of Cognitive Radio (CR) trader transmission power and interference tempera- ture constraints. First, we propose the interfer- ence constraint which ensures that the Quality of Service (QoS) standards for primary users is considered and a non-cooperative game power control model. Based on the proposed model, we developed a logical utility function based on the Signal-to-Interference-Noise Ratio (S/NR) and a novel algorithm network power control. that is suitable for CR Then, the existence and uniqueness of the Nash Equilibrium (NE) in our utility function are proved by the principle of game theory and the corresponding optimi- zations. Compared to traditional algorithms, the proposed one could converge to an NE in 3-5 iterative operations by setting an appropriate pricing factor. Finally, simulation results ver- ified the stability and superiority of the novel algorithm in flat-fading channel environments. 展开更多
