Abstract We show that the symplectic contraction map of Hilgert–Manon–Martens [9], a symplectic version of Popov’s horospherical contraction, is simply the quotient of a Hamiltonian manifold $M$ by a “stratified null foliation” that is determined by the group action and moment map. We also show that the quotient differential structure on the symplectic contraction of $M$ supports a Poisson bracket. We end by proving a very general description of the topology of fibers of Gelfand–Zeitlin (also spelled Gelfand–Tsetlin or Gelfand–Cetlin) systems on multiplicity-free Hamiltonian $U(n)$ and $SO(n)$ manifolds.

A method is described in an attempt to make medical records suitable for epidemiologigri: purposes. Every case of a disease is recorded on an appropriate punched card with the object of working towards a general description of a disease through the collation of several cases of the same diagnosis. This punched card represents a very great condensation of the original record. Special care has been applied to state as precisely as possible the time variable, particularly as far as its origin and unit of measure are concerned, in order to demonstrate the existence of causal relations between diseases. Such cards are also intended to make easier statistical studies in clinical pathology, in evaluation of new laboratory techniques, and in therapeutical trials.

So far, in implementing school strategies, they tend not to utilize Information and Communication Technology (ICT), despite the availability of ICT resources available. Stages of strategic management are needed to generate the vision, mission, objectives, policy, program, budget, and procedures as well as control and evaluation process as an effort to utilize ICT to improve school quality. Based on the interpretation and the results of the study, it is concluded that schools have organized stages in strategic management that enable schools to have a quality profile. The impact of effective utilization of ICTs for schools is the achievement of effective school management, as per the National Education Standards, which is characterized by effective planning, implementation, control, and evaluation of school ICTs.The purpose of this study is to get a general description, describe, and reveal the Strategic Management of Information and Communication Technology Utilization to Improve the Quality of School Learning in Ciledug Al Musaddadiyah Vocational High School and Garut 1 Vocational High School, both on environmental analysis, strategic formulation, implementation and strategic evaluation. The research method used in this research is the case study method, because the problems studied occur in the place and situation of Ciledug Al Musaddadiyah Vocational School and Vocational High School 1 Garut. The use of case study models in this study is based on the consideration that to provide an overview of the strategic management activities of the use of ICTs carried out at vocational high schools with the ultimate goal of being able to improve the quality of school learning. Based on observations in the field of SMK 1 Garut and SMK Al Musaddadiyah Ciledug Garut is one of the public schools and private schools that have these advantages.

Verbal Behavior (VB) was the most important Skinner’s work. Generic self-analysis of the behavior registered on VB appears in its final parts and in others of the author’s books. This paper describes the functions of two specific under-classes of quoting episodes with transcription from other author’s text emitted by Skinner on VB. It deals with a historical research of the VB as the register of Skinner’s verbal behavior. From the general description of quoting with transcription, it establishes a functional analysis of two distinct under-classes by its autoclitic frame, according to a behavioral hermeneutics: a method that instructs a description of the controls on the interpretation. The formal-functional variations of quoting are informed: accurate verbal stimuli evocated the “argumentative” quoting (emitted with descriptive autoclitics) and the non-accurate, the “counter-argumentative” ones (emitted with manipulative and/or negation autoclitics). Despite of the difficulty in discriminating all controls on the interpretation, the paper shows the functional consistency of some the devices of persuasion in the Skinnerian rhetoric.
