Historic Background

For didactics, systematically structured teaching contents are desirable, and natural systems would be most comprehensible. We tested whether serrada-escrima styles (SES), a type of Filipino martial arts, represent a natural system. Natural systems are considered to have an inner coherence. This means that based on some elements of the system the other elements can be predicted, based on knowledge of the characteristics of the elements of the system. SES is a good candidate to test this hypothesis, as it embraces only a relatively small set of techniques. It appears that SES indeed represents a natural, coherent system with 12 elements that can be grouped into three also coherent sets, each with four techniques. One basic pre-assumption is necessary to make SES a natural system; this pre-assumption is derived from knowledge of medieval European sword fighting, more precisely Messerfechten. We furthermore discuss indications for the historic background of SES.

Training Concept

During our childhood, even early after being borne, we have innate features for self-defense instinctively which are barely noticed. On the other hand, nowadays, martial arts and self-defense practices are being steadily educated as a popular form of training. These approaches can end up with consequences in real combats. The purpose of the present paper is to introduce a new training concept by considering very basic and instinctive defensive movements exhibited by a human since his/her birth and develop and follow these features for self-defense in adolescence. This new concept will indicate that some martial arts (i.e. martial skills – different from common interpretation of a martial art) have been with us since our birth. Here we will demonstrate that even a cutie infant can provide us with noble self-defense ideas.

Initial Knowledge

One of the tools to determine the recommended order of the courses to be taught is to set the prerequisites, that is, the conditions that have to be fulfilled before commencing the study of the course. The recommended sequence of courses is to follow logical links between their logical units, as the basic aim is to provide students with a coherent system according to the Comenius' principle of continuity. Declared continuity may, on the other hand, create organizational complications when passing through the study, as failure to complete one course may result in a whole sequence of forced deviations from the recommended curriculum and ultimately in the extension of the study period. This empirical study deals with the quantitative evaluation of the influence of the level of initial knowledge given by the previous study on the overall results in a certain follow-up course. In this evaluation, data were obtained that may slightly change the approach to determining prerequisites for higher education courses.

Vertex Transitive Graph

Abstract Does every $n$-vertex Cayley graph have an orthonormal eigenbasis all of whose coordinates are $O(1/\sqrt{n})$? While the answer is yes for abelian groups, we show that it is no in general. On the other hand, we show that every $n$-vertex Cayley graph (and more generally, vertex-transitive graph) has an orthonormal basis whose coordinates are all $O(\sqrt{\log n / n})$, and that this bound is nearly best possible. Our investigation is motivated by a question of Assaf Naor, who proved that random abelian Cayley graphs are small-set expanders, extending a classic result of Alon–Roichman. His proof relies on the existence of a bounded eigenbasis for abelian Cayley graphs, which we now know cannot hold for general groups. On the other hand, we navigate around this obstruction and extend Naor’s result to nonabelian groups.

End Members

Systems philosophy provides the theoretical framework linking diverse applications of computer simulation. Natural systems and man-made systems may be regarded as end members of a spectrum of system types. Simula tion of man-made systems employs operations research techniques; the objectives of simulation are to optimize system design and to test the performance of models under differing parameter settings. Simulation of natural systems cannot readily utilize specialized simulation lan guages, as these are designed primarily for industrial and business applications. The objectives of simulating natu ral systems are normally to test alternative models and to see how they react under various conditions; the natural system itself cannot be changed (unless it is partly man- influenced)-only the model can.

The One

The 2011 Japanese earthquake and subsequent malfunction at the Fukushima nuclear power plant occurred at the apex of a complex crisis of nature. While some commentators claim that the Fukushima malfunction was the result of a ‘natural disaster’, others situate the event within a broader context of human interventions in ecological and natural systems. Exercised through the global mediasphere, these environmental language wars are formed within crisis conditions and a crisis consciousness that have extensive genealogical roots. This article examines the crisis of nature in terms of contemporary and genealogical language wars that are embedded in a cultural politics of apocalysm. In particular, the article problematises the concept of ‘nature’ in terms of the disaggregation of human and non-human life systems. It argues that this disaggregation confounds the cultural politics of life (-death) systems, leading to excessive violence on the one hand, and Romantic idealisation on the other. The article recommends a reconceptualisation of nature that implicates all humans and human desires across the global mediasphere.

Martial Art

The martial art of silat in Minangkabau, which is usually called silek, has its own uniqueness in terms of terms and movements. Silek in Minangkabau is a legacy from the Minangkabau ancestors that still exists and develops today. The requirements that must be possessed in this silat include cloth, knives, sewing needles, mirrors, rice and money that have meaning in this silat tradition. In addition, there are other elements in these martial arts which also have meaning in terms of movement, clothing and place of implementation. This study focuses on the meaning of the terms and movements used in the silek of Tuo gunuong in Kubu Gadang village. The informants in this study are traditional elders and people who still practice silat as a martial art and understand the terms and meanings of the movement.

Indeed, it is in these unique responses that most martial arts distinguish themselves. However, this paper examines the role of the aggressor during training; specifically, in the martial art of Aikido and draws an analogy between the role of an aggressor during Aikido practice and the actions of a member of the loyal opposition in a democracy. A commitment to a set of rules that govern and protect the participants and a commitment to maintain a rich, creative tension mark both the vibrant interactions of an Aikido dojo and democratic life in a multicultural society.</span></span></span></p>

Artificial Classification

Linnaeus was educated in Sweden, and became a doctor of medicine in Harderwijk, Holland, in 1735. He visited other European countries then, but he never left Sweden after his return in 1738. After practising as a physician in Stockholm, he moved to Uppsala University as professor of medicine and botany in 1741. He articulated four different but complementary ways of understanding nature – through two kinds of classification, and through what can be called developmental and functional/ecological interactions. Linnaeus is best known for his classificatory work, for which he received material from all over the world. His classificatory precepts are elaborated in the Philosophia botanica of 1751, an enlarged version of the 365 aphorisms of his Fundamenta botanica of 1735; the other aspects of his work are diffused through his writings. His artificial classification system, initially very popular, was replaced by the ’natural’ system, more slowly in botany than in zoology, and more slowly in England than in some other countries. Current biological nomenclature is based on his Species plantarum, edition 1 (for plants), and Systema naturae, edition 10 (for animals). His codification of botanical terms remains influential. Almost 200 dissertations, most written by Linnaeus, were defended by his students. In these and other less well-known works, including the unpublished Nemesis divina (Stories of Divine Retribution), he covered a wide range of subjects. Quinarian thinking is noticeable in Linnaeus’ work – there are five ranks in systems, five years’ growth in flowers – and in some of the occult works that he knew. He also shows a strong combinatorial bent and a tendency to draw close analogies between the parts of animals and plants.
