Abstract ChemInform is a weekly Abstracting Service, delivering concise information at a glance that was extracted from about 100 leading journals. To access a ChemInform Abstract of an article which was published elsewhere, please select a “Full Text” option. The original article is trackable via the “References” option.The pressure-induced structural phase transitions of e- and γ-CL-20 were studied by Raman and mid-infrared spectroscopy up to 60 GPa. In this work, the phase transition of CL-20 from the e-phase to the γ′-phase starts at 0.9 GPa and ends at 4.4 GPa. The γ′-phase in this work is distinctly different from the γ-phase recognized by the energetic community in terms of the structure and properties. Subsequently, the η phase starts at 6.9 GPa and ends at 10.6 GPa because of the slight cage distortion. With further increase of the loading pressure, two new phases, φ and ι, were observed at 28 and 50 GPa, respectively. The infrared results are consistent with Raman results and show that similar phase regions are observed for CL-20 under high pressures. The behavior of the γ-phase under pressure indicates that the ζ-phase appears at 1.3 GPa and sustains its stability up to 47.4 GPa. The current results prove that the newly discovered γ′-phase is evidently distinct from the γ-phase and they undergo different phase transition routes under loading compression.

Nowadays aesthetics studies makes transition,as one of China's classical aesthstic source,Confucius aesthstic approach transition research mainly concentrate on three respects: first,Breaks through the epistemology as well as the Soviet Model to non-concept and non-ready-made method transition;second,it is the transition from nature of subject to nature of intersubjectivity;third,the transition method to present-visual-experience.

As a part of early education for special children,transition education had been put on emphasis in the 1980s.This paper introduces some contents generally,incluling:the definition of transition education,some viewpoints on transition education,some models of transition education,and some laws and practice of transition education.Finally,the effect of the transition education for preschool special children is brought up.

이 연구의 목적은 학교장의 전문성을 규범적 전문성과 실천적 전문성으로 개념화하고, 학교장 승진 임용 시기를 기점으로 전문성 전환이 이루어지는 양상을 탐색하는 데 있다. 이 같은 연구의 목적을 달성하기 위해 연구참여자를 모집해 면담을 통해 자료를 수집하였다. 특히, 이 과정에서 질적 연구방법론의 일종인 프레임워크 분석법을 활용하였고 이론적 분석틀은 Schlossberg의 전환이론에 기초해 연구목적에 부합하도록 재구성하였다. 이 연구의 주요 분석결과는 다음과 같다.BR 첫째, 학교장 전문성 측면에서 보면 국내에서 학교장이 되었다는 것의 의미는 실천적 전문성보다 규범적 전문성의 성취에 보다 가까운 것으로 현장에서 받아들여졌다. 법령상 규정되어 있는 자격을 확보한 뒤에 획득되는 규범적 전문성이 성공적인 직무수행을 위해 필요한 실천적 전문성보다 상대적으로 부각되어 나타난 것이다. 둘째, 학교장 승진 임용 이후의 실천적 전문성 발달과 관련해 국내 학교장이 보유한 잠재자산은 상황, 자아, 지원, 전략 등의 차원에서 드러났다. 셋째, 학교장은 경력을 쌓으면서 실천적 전문성 증진과 관련된 잠재자산을 점진적으로 강화하는 것으로 관측되었다.BR 이와 같은 분석결과를 바탕으로 국내 학교장의 전문성 전환과 관련해 다음과 같이 논의를 전개하였다. 첫째, 학교장이 겪는 전문성 전환은 생존형의 양상을 보이고 있다는 면에서 승진 임용을 기준으로 발생하는 전문성 사이의 간극을 줄여줄 수 있는 지원이 요청된다. 둘째, 전문성 전환의 선순환을 구축하는 방안의 일환으로 ‘이질 집단으로서의 학교장’을 인정하고, 개별화된 멘토링 지원을 정교화하는 노력이 필요하다. 셋째, 전문성 전환에서 나타나는 문제의 불식을 도모하려면 실천적 전문성 관련 표준의 마련을 위한 노력이 있어야 하고, 규범적 전문성과의 합일을 지향하는 방향으로 나아가야 한다.

Readers can skip words or track back to an earlier point in the paragraph; listeners have to rely on the speaker to provide them with help to build a coherent structure of the message. In general it is recommended that a speaker should make the transition between topics explicit by using transition sentences. Such sentences bridge ideas and aid understanding. This paper investigates whether the use of transition sentences has the effects that modern advisors predict. Does the use of transition sentences result in a more coherent representation of the message of the speaker and in a higher appreciation of the speech itself? To explore these questions three variants of one 13-minute lecture were constructed; the only difference among the three was the presence (and place) of a series explicit transition sentences. The results show that the power of such sentences is restricted. But-when well placed-they enhance the perception of the presentation by the audience.

The purpose of this study is to find out types and the dominant one of transition signals used in short stories. Research method used in this study is descriptive qualitative by doing library research. The data were collected by analyzing the transition signal used in five short stories. The results shows that the transition signals used in short stories are the transition signal indicates time, comparison, additional idea, and contrast. The dominant transition signal used is the transition signal indicates additional idea. The findings shows that the transition signal used on the five short stories is developed in a single central theme.

Effective transitions are a challenge – linking the old with the new, working efficiently and effectively, all the while keeping the vision of the future firmly in mind. There is a tendency to rely on techniques that have sufficed in the past, some more successful than others. An effective transition guides the reader, serving as a connection between ideas. The transition may also help the reader to anticipate the ideas that are about to be presented, offering a “signpost” of sorts. Whatever the purpose, the transition provides the coherence, and perhaps even grace, that is otherwise absent in so much legal writing. Humbly, this articles offer you hope for a smooth transition.
