In every field of human endeavor, when a view is expressed, sharp and profound differences of opinion ensue. Initially, we coin this phenomenon as ＂understanding blindness＂ or ＂mind＇s awareness.＂ Thereafter, we decide to refer to it as ＂mind blindness,＂ a concept introduced to science by Professor Simon Baron-Cohen, who coins it for a cognitive disorder associated with autism, Asperger＇s syndrome, and schizophrenia. Baron-Cohen＇s usage has subsequently been extended to dementia, bi-polar disorders, antisocial personality disorders, and even normal aging. In our view, definition and identification of ＂mind blindness＂ in philosophy, religion, science, medicine, and at end-of-life care can help mankind to better understand mechanisms of human behavior, and the causes of conflicts, controversies, contradictions, and sharp differences of opinion in human life, and even to solve some of them.展开更多

In this sense, it would be a reasonable idea that an individual should benefit from art education in order to have a complete education, since art is not just creating an aesthetic object or being aware of staying against an aesthetic object. Art means that it occurs in every stage, in every action, in all attitudes and behaviors of human being realized in an aesthetic concern without thinking When the individuals having an art education in primary and secondary education start their education in a higher education program in a faculty or department other than art education, art education loses its continuity. However art education should be continuous and it is of importance in terms of its contribution to this continuity since the studies of art education for the adults out of formal education would support it. The purpose of the current study was to determine the needs of adults and also the support that would be obtained from any kind of educational activities for art education, and to propose some recommendations in this sense展开更多

Among all,the mass transport of nanofluidics is most concerned. Besides that, the heat transfer of a fluid flow in nano or micro channels is always considered with adding nanoparticles into the flow, so as to enhance the heat transfer by convection between the fluid and the surface. However, for some applications with around 1 nm channels such as nano filtration or erosion of rocks, there should be no nanoparticles included. Hence, it is necessary to figure out the heat transfer mechanism in the single phase nanofluidics. Via non-equilibrium molecular dynamics simulations, we revealed the heat transfer inside nanofluidics and the one between fluid and walls by setting simulation into extremely harsh condition. It was found that the heat was conducted by molecular motion without temperature gradient in the area of low viscous heat, while it was transferred to the walls by increasing the temperature of fluids. If the condition back to normal, it was found that the viscous heat of nanofluidics could be easily removed by the fluid-wall temperature drop of less than 1 K.展开更多

Unfortunately, children＇s spare time is nowadays very frequently organized for the sake of brushing up children＇s knowledge, skills, and competences, which is accomplished by means of escalating extra-curriculum activities. When expressed by teacher and parents, these ambition-related attitudes pave the way for the disappearance of children＇s personal interests and motivations to perform complicated tasks which are perceived as unwanted or obscure by the affected children themselves. This form of adults＇ behavior may lead to the feelings of frustration, stress, demotivation, or rebellion on behalf of their children. The said emotional states, especially in relation to the lack of spontaneous play, give rise to serious psychic dysfunctions, and the instability of children＇s psychic balance. It may also pave the way for various forms of destructive behavior that mostly characterize children of younger school age who are about to start schooling.展开更多

Assuming the perspective that to be an entrepreneur is basically an attitude towards life and the world, there proposed holistic, constructivist and experiential processes and strategies for entrepreneurship education. The ＂entrepreneur XXI＂, must be able to undertake a social function of change, so, an economical and social development more human, ethical and intelligent. Under this assumption, the ＂Tree Model for the Development of Entrepreneurial Competencies＂, that will be discussed globally in the second part of this article, suggests a dynamic and experiential approach ofentrepreneurship education based on the qualification of people＇s behaviour, self-esteem, competencies and experiences; a profile of key behavioural and performance competencies （root）, experimental pedagogical procedures （trunk） and real results within group projects （fruits）. This model has been developed during the last decade （2001-2011）, using a multidisciplinary research-action procedure, within business, education （at different teaching levels） and social project environments.展开更多

In turn, the kinematics of a robot manipulator can be described by its forward and reverse models. The inverse kinematic model, which provides the status of the joints according to the desired position for the tool of the robot, is typically taught and described in robotics classes through an algebraic way. However, the algebraic representation of this model is often difficult to obtain. Thus, although it is unquestionable the need for the accurate determination of the inverse kinematic model of a robot, the use of ANNs （artificial neural networks） in the design stage can be very attractive, because it allows us to predict the behavior of the robot before the formal development of its model. In this way, this paper presents a relatively quick way to simulate the inverse kinematic model of a robot, thereby allowing the student to have an overview of the model, coming to identify points that should be corrected, or that can be optimized in the structure of a robot.展开更多

Due to fatigue and cyclic loading, the pullout or debonding phenomenon often occurs in osteonal and interstitial tissue bone. The study aims to construct a fiber-reinforced composite material debonding model for cortical bone, in which the bonding condition along the osteon, cement line and interstitial tissue bone are assumed to be imperfect. In the study, we used the complex variable method to obtain series representations for stress fields in the osteon, cement line and the interstitial tissue bone with a radial crack. The effects of material properties of osteon and cement line, crack position, and varying degrees of debonding on the fracture behavior were investigated by computing the stress intensity factor （SIF） in the vicinity of the microcrack tips. The investigation results indicated that the cement line was important for controlling the fracture toughening mechanisms and that the level of imperfect bonding among osteon, cement line and interstitial tissue bone had a pronounced effect on the crack behavior and should not be ignored.展开更多

While EB models use a global approach to model aggregate population, net- work models focus on the behavior of individuals in the population. The two approaches have been used in several areas of research, including finance, computer science, social science and epidemiology. In this study, epidemiology is used to contrast EB models with network models. The methods are based on the assumptions and properties of compartmental models. In EB models we solve a system of ordinary differential equations and in network models we simulate the spread of epidemics on contact networks using bond percolation. We examine the impact of network structures on the spread of infection by considering various networks, including Poisson, Erd3s R6nyi, Scale-free, and Watts- Strogatz small-world networks, and discuss how control measures can make use of the network structures. In addition, we simulate EB assumptions on Watts-Strogatz net- works to determine when the results are similar to that of EB models. As a case study, we use data from the 1918 Spanish flu pandemic and that from measles outbreak to validate our results.展开更多
