Methods Five hundred and sixty pupils graded from 1 to 6 in an elementary school were investigated. According to the pupil rating scale revised screening for learning disabilities (PRS), combined Raven’s test (CRT) and achievement of main courses, 35 of 560 pupils were diagnosed as LD children. Thirty-five children were selected from the average children and 35 from advanced children in academic achievement equally matched in class, gender, and age with LD children as control groups. The three groups were tested by Piers-Harris children’s self-concept scale. Basic information of each subject was collected by self-made questionnaire. Results Compared with the average and advanced children, LD children got significantly lower scores in self-concept scale. Based on logistic regression analysis, 3 factors were identified, including family income per month, single child and delivery model. Conclusion The results suggest that self-consciousness of children with LD is lower than that of normal children.展开更多

The desired results for micromorphic continuum mechanics and couple stress theory are naturally obtained via direct transitions and reductions from the coupled conservation law of energy for micropolar continuum theory, respectively. The basic balance laws and equations for micromorphic continuum mechanics and couple stress theory are constituted by combining these results derived here and the traditional conservation laws and equations of mass and microinertia and the entropy inequality. The incomplete degrees of the former related continuum theories are clarified. Finally, some special cases are conveniently derived.展开更多

In this novel, Twain not onlydescribes the courageous adventures of Huck, but also his psychological or spiritual growth. Due to the social and cultural back-ground of that time and general cultural concept the protagonist was instilled before, the conflicts of the protagonist's self-con-sciousness appear many times in this novel when the issue of slavery is concerned. However, through the protagonist's inner con-flicts, he finally gains spiritual growth and obtains a higher level of moral maturity.展开更多

The latter holds that Damasio does not distinguish the concepts of phenomenal consciousness and self-consciousness and this has two kinds of consequences. One is that it cannot satisfactorily explain certain mental states (dreams, vegetative states); the other is that it has harmful consequences for animal ethics. I maintain that to compare the two theories we can only rely on our pre-theoretical intuition of consciousness. Thus, I argue that Dam^tsio's theory combines more with our intuitions. One of the reasons is that the cases that Block describes as phenomenal consciousness without access consciousness (and without self-consciousness) are best explained as being cases of mind without consciousness. Dam^sio's theory can also explain those referred cases which are theoretically problematic. Moreover, Dam^isio has a threshold model (an expression by Barry Dainton), which is something that Block seems to ignore. This model fits well with the intuitions and neurological knowledge that we normally have on animal consciousness. Dam^isio's core self and his theory of emotions and feelings allow us to understand why we feel compassion for animals. Therefore, we are able to develop an animal ethics, which does not mean that we are required to do so. So even though Damasio does not solve the mystery of consciousness, he should not be the subject of Block's criticism.展开更多

The current increase in the speed of natural-origin structure growth may be linked to their superior mechanical properties and environmental resilience. Biological composite structures with helicoidal schemes and designs have remarkable capacities to absorb impact energy and withstand damage. However, there is a dearth of extensive study on the influence of fiber redirection and reorientation inside the matrix of a helicoid structure on its mechanical performance and reactivity. The present study aimed to explore the static and transient responses of a bio-inspired helicoid laminated composite(B-iHLC) shell under the influence of an explosive load using an isomorphic method. The structural integrity of the shell is maintained by a viscoelastic basis known as the Pasternak foundation, which encompasses two coefficients of stiffness and one coefficient of damping. The equilibrium equations governing shell dynamics are obtained by using Hamilton's principle and including the modified first-order shear theory,therefore obviating the need to employ a shear correction factor. The paper's model and approach are validated by doing numerical comparisons with respected publications. The findings of this study may be used in the construction of military and civilian infrastructure in situations when the structure is subjected to severe stresses that might potentially result in catastrophic collapse. The findings of this paper serve as the foundation for several other issues, including geometric optimization and the dynamic response of similar mechanical structures.展开更多

Space and time have been shown in the Unitary Quantum Theory (UQT) not to be connected one with the other, unlike in the Special Theory of Relativity. In UQT, time becomes Newtonian again, and the growth of the particle’s mass with growing speed proceeds from other considerations of physics. Unlike the quantum theory, the modern gravitation theory (the general theory of relativity) is not confirmed by experiments and needs to be considerably revised.展开更多

文摘Using the Skyrme density functional theory,potential energy surfaces of^(240)Pu with constraints on the axial quadrupole and octupole deformations(q_(20)and q_(30))were calculated.The volume-like and surface-like pairing forces,as well as a combination of these two forces,were used for the Hartree–Fock–Bogoliubov approximation.Variations in the least-energy fission path,fission barrier,pairing energy,total kinetic energy,scission line,and mass distribution of the fission fragments based on the different forms of the pairing forces were analyzed and discussed.The fission dynamics were studied based on the timedependent generator coordinate method plus the Gaussian overlap approximation.The results demonstrated a sensitivity of the mass and charge distributions of the fission fragments on the form of the pairing force.Based on the investigation of the neutron-induced fission of^(239)Pu,among the volume,mixed,and surface pairing forces,the mixed pairing force presented a good reproduction of the experimental data.

文摘The travel time of rock compressional waves is an essential parameter used for estimating important rock properties,such as porosity,permeability,and lithology.Current methods,like wireline logging tests,provide broad measurements but lack finer resolution.Laboratory-based rock core measurements offer higher resolution but are resource-intensive.Conventionally,wireline logging and rock core measurements have been used independently.This study introduces a novel approach that integrates both data sources.The method leverages the detailed features from limited core data to enhance the resolution of wireline logging data.By combining machine learning with random field theory,the method allows for probabilistic predictions in regions with sparse data sampling.In this framework,12 parameters from wireline tests are used to predict trends in rock core data.The residuals are modeled using random field theory.The outcomes are high-resolution predictions that combine both the predicted trend and the probabilistic realizations of the residual.By utilizing unconditional and conditional random field theories,this method enables unconditional and conditional simulations of the underlying high-resolution rock compressional wave travel time profile and provides uncertainty estimates.This integrated approach optimizes the use of existing core and logging data.Its applicability is confirmed in an oil project in West China.
文摘The authors discuss contradictions between the principal branches of the modern physical picture of the universe. Space and time have been shown in the Unitary Quantum Theory (UQT) not to be connected one with the other, unlike in the Special Theory of Relativity. In UQT, time becomes Newtonian again, and the growth of the particle’s mass with growing speed proceeds from other considerations of physics. Unlike the quantum theory, the modern gravitation theory (the general theory of relativity) is not confirmed by experiments and needs to be considerably revised.
文摘The notion of"Queen's English",depending on who is the ruler of the time,could be traced back to the sixteenth century,when the idea that the monarch's usage of the language should be a model in speech and writing.That is where the"Elizabethan English" originated from.From the linguistic point of view,Elizabethan English is categorized into Early Modern English,which dominantly spanned the Renaissance,Elizabethan era and Shakespeare.On a smaller scale,this paper focused upon language itself,trying to exemplify the rise of Elizabethan Language from the second half of 16th century to the outset of 17th century by presenting two factors of self-consciousness and the relevant policy.
文摘The Black self-consciousness is an eternal literay theme seriously treated in American Literature and Black Literature in particular,This paper gives a survey of the progress of Black self-consciousness in which Black Americans have neen struggling continously to earn their freedom and equality,and later to restore their own self-respect and confidence.The progressive self-consciousness is evidently demonstrated in this paper by comparative analysis of various Black figures,from the obedient and meek Ngro slaves represented by Uncle Tom to the rebellious and difi-ant characters portrayed by Richard Wright and Ralph Ellison,In reality,the promising generation involved in the Harlem Renaissance have taken some measures to search for their own identity in a highly organized and prejudiced society.
