It seems a pity that Hamiltonian dynamics—contact transformations and so on—is regarded as a fearsome subject, too time-consuming to teach to most students; for it is the one branch of dynamics to point a way to new developments in this century. Moreover the basic ideas are extremely simple, but presented in an unfortunate way in all the text-books.

Three years ago Sophie Till started working with pianist Edna Golandsky, the leading exponent of the Taubman Piano Technique, an internationally acclaimed approach that is well known to pianists, on the one hand, for allowing pianists to attain a phenomenal level of virtuosity and on the other, for solving very serious piano-related injuries. Till, a violinist, quickly realized that here was a unique technical approach that could not only identify and itemize the minute movements that underlie a virtuoso technique but could show how these movements interact and go into music making at the highest level. Furthermore, through the work of the Golandsky Institute, she saw a pedagogical approach that had been developed to a remarkable depth and level of clarity. It was an approach that had the power to communicate in a way she had never seen before, despite her own first class violin training from the earliest age. While the geography and “look” on the violin are different from the piano, the laws governing coordinate motion specifically in playing the instrument are the same for pianists and violinists. As a result of Till’s work translating the technique for violin, a new pedagogical approach for violinists of all ages is emerging; the Taubman/Golandsky Approach to the Violin. In reflecting on these new developments, Edna Golandsky wrote, “I have been working with the Taubman Approach for more than 30 years and have worked regularly with other instrumentalists. However, Sophie Till was the first violinist who asked me to teach her with the same depth that I do with pianists. With her conceptual and intellectual agility as well as complete dedication to helping others, she has been the perfect partner to translate this body of knowledge for violinists. Through this collaboration, Sophie is helping develop a new ‘language’ for violinist that will prevent future problems, solve present ones and start beginners on the right road to becoming the best they can be. The implications of this new work for violinists are enormous.”

Due to the fact that the modern world is in the context of globalization, the development of the countries of the world is accompanied by a qualitative increase in technology in the field of science and technology, in connection with which, there is an internationalization of scientific developments, high-tech production, as well as competition between countries over the distribution of resources is intensifying, in terms of new developments and development in general. Cooperation in itself bears the potential of mutual assistance, joint solution of a set of international, scientific problems by the participating countries. For this reason, modern scientific cooperation is a consequence of well-built scientific diplomacy. Scientific diplomacy is called upon to promote the development of scientific cooperation; it is aimed at maintaining partner diplomatic relations, which, on the one hand, can use science to bring together interstate priorities, and, on the other hand, contribute to the development of science itself. The latest diplomacy has adopted scientific approaches and is actively solving modern challenges facing governments and countries. The article discusses the work of international organizations in the designated area of research, provides Kazakhstani experience in resolving the issue

Internationalizing the Japanese students at KOSEN has proven difficult. While KOSEN welcomes international students with the hope of internationalizing the almost entirely Japanese student body, the challenge has been to get the Japanese students to interact with the international students and take advantage of the opportunity. Far too often international students live in a bubble and have meaningful contact with only a few students. This leaves the international students feeling isolated and the Japanese students not benefiting from the opportunity that KOSEN is trying to provide. Ariake KOSEN attempted to address this problem in two ways. A discussion class which included international students was created where the students were expected to discuss pre-assigned topics in small groups over the course of a semester. These groups often contained an international student. This forced exposure created a chance for Japanese students to communicate with international students. This communication was then seen continuing well beyond the discussion exercises. A survey was given at the completion of the one semester class to evaluate effectiveness. The results show that students found the opportunity to be helpful and in line with their own learning goals. Another approach was to create a more casual place for students to gather and interact with international students. An English Lab was created to give the students a place to interact outside of the traditional classroom atmosphere. This second effort is just in the beginning stages but the basic ideas are laid out in this paper. Anecdotal evidence seems to suggest that the Lab is working, with usage on the part of Japanese students being high, but the international students seem less inclined to use the room.

The future of sustainable development in Africa and for its growing population will depend on investments which might come mostly from abroad attracted by a favourable investment climate (or ecosystem). It is rather doubtful that the actual („old“) international legal framework for investment-related and investment-specific measures which does hardly create an adequate balance between the interests of all important public as well as private stakeholders would meet the requirement of today and tomorrow. But any alterations or improvements must start from the present state of things. So, this study looks at the different levels and various instruments dealing with traditional standards of investment and investor protection, e.g. BITs und TIPs, and at the activities of global, regional and sub-regional organizations (in particular EU and OHADA). Moreover, new developments at global and regional levels are discussed including trends showing a somewhat specific African approach to investment issues (“Africanization”). Finally, a very important topic, i.e. the relation between investment protection and human rights (of investors and of other people negatively affected by relevant activities), is described and assessed in more detail. A second part of the analysis will turn to elaborating on dispute settlement and enforcement issues since till today, there seems to be a sharp distinction between Investor-State- Dispute Settlement (ISDS) by way of mediation, conciliation and arbitration on the one hand and judicial redress by national courts (of home, host or third States) on the other.

Science and religion are a unity. The difference between the two lies only in the way of view. Knowledge comes from the One God. All kinds of approaches to reality are ultimately capable of being integrated and integrated with the contemplation of the concept of God's oneness. Scientific activity is closely related to the implementation of education. The implementation of education is always based on curriculum development. The existence of curriculum development is based on the emergence of future challenges and competencies. This research aims to describe the design of integrative science and religion in the device and the implementation of learning. The research method used is descriptive qualitative, sample in this research is teacher at MTsN Kota Salatiga. The integration of science and religion is seen only in the implementation of learning, where teachers have introduced the relationship of science and religion through connecting with the verses of the Qur'an. The integration that has been implemented in the madrasah is already on the operational level.

The standard assumption of rational, forward looking behavior has been heavily questioned given the impossibility of understanding some risk consumption behaviors within such a framework. The Becker and Murphy theory of rational addiction made a start on this debate fostering new refinements within the original rational theory framework as well as promising approaches based on the latest developments of cognitive science.This paper makes an overview confronting two main approaches highlighting their different time preferences assumptions. On the one hand the debate assumes rationality even in extreme situations of risk consumption - addictive behavior. On the other, new developments in the explanation of habits and addictive behaviours take an economic-psychological approach into consideration and have substantially different policy implications.

We simulate the dynamics of many-particle system of bosons and fermions using discrete time quantum walks on lattices. We present a computational proof of the behaviour of the simulated systems similar to the one observed in Hamiltonian dynamics during quantum thermalization. We record the time evolution of the entropy and the temperature of a specific particle configuration during the entire dynamics and observe how they relax to a state which we call the quantum walk thermal state. This observation is made on two types of lattices while simulating different numbers of particles walking on two grid graphs with 25 vertices. In each case, we observe that the vertices counting statistics, the temperature of the indexed configuration and the dimension of the effective configuration Hilbert space relax simultaneously and remain relaxed for the rest of the many-particle quantum walk.

It was only six years ago that C. J. Slade wrote his memorable article “The Myth of Mistake in the English Law of Contract” in which he placed the whole subject of mistake in a new and agreeable perspective. “Mistake as such,” he declared, “has no operative effect whatever at law.”This was good news for the student; but problems of error in persona still had to be solved, and for these Mr. Slade proposed a simple application of the basic principles of offer and acceptance. The test was whether A's offer was addressed to B and B's acceptance addressed to A, their intention being construed objectively unless that of the one was known to the other, in which case the actual intention of the former determined the matter. The authorities, for the most part, ranged themselves in substantial support, and rationality, it seemed, had been injected at last into this confused branch of the law.This reassurance has now been disturbed by the case of Ingram v. Little, which reminds us that the offer and acceptance test is no magic formula acting as a ready panacea for all the ills caused by error in persona.The facts which gave rise to Ingram v. Little are by now well known. Three ladies who wished to sell their car were offered an acceptable price by a stranger, but they made it plain they would not accept payment by cheque. He then pretended to them that he was a certain P. G. M. Hutchinson and quoted an address which the ladies found to be the one shown beside that person's name in the telephone directory.

Cluster state computation or the one way quantum computation (1WQC) relies on an initially highly entangled state (called a cluster state) and an appropriate sequence of single qubit measurements along different directions, together with feed-forward based on the measurement results, to realize a quantum computation process. The final result of the computation is obtained by measuring the last remaining qubits in the computational basis. In this short tutorial on cluster state quantum computation, we will also describe the basic ideas of a cluster state and proceed to describe how a single qubit operation can be done on a cluster state. Recently, we proposed a repeat-until-success (RUS) scheme that could effectively be used to realize one-way quantum computer on a hybrid system of photons and atoms. We will briefly describe this RUS scheme and show how it can be used to entangled two distant stationary qubits.
