Adolescent language as affectively coded behavior: findings of an observational research project.

This study aims to formulate a minimal typology of the speech-programming categories of adolescent language. In all, thirty-six adolescents (ages 13 to 18) living in the city of Toronto were recorded both in spontaneous conversational settings and in formal interview sessions. The ensuing analysis of these recordings led to the postulation of three basic categories: emotive, connotative, and socially coded language programming. These categories can be seen to provide a framework within which to conduct more specific kinds of research on adolescent language.

PALM--a pattern language for molecular biology.

This paper presents a new pattern language, PALM, for describing patterns in molecular biology sequences. The language is intended for representing knowledge about such patterns in a declarative, clear and concise way. It is also shown that its expressive power enables the definition of any regular or context free language, and also higher languages in the Chomsky hierarchy by parameter attachment, variables and procedural attachment. It is also possible to define approximate patterns. The language is rigorously defined, and several examples of its use and expressive power are given.

SIMPSON: a general simulation program for solid-state NMR spectroscopy.

A computer program for fast and accurate numerical simulation of solid-state NMR experiments is described. The program is designed to emulate a NMR spectrometer by letting the user specify high-level NMR concepts such as spin systems, nuclear spin interactions, RF irradiation, free precession, phase cycling, coherence-order filtering, and implicit/explicit acquisition. These elements are implemented using the Tcl scripting language to ensure a minimum of programming overhead and direct interpretation without the need for compilation, while maintaining the flexibility of a full-featured programming language. Basically, there are no intrinsic limitations to the number of spins, types of interactions, sample conditions (static or spinning, powders, uniaxially oriented molecules, single crystals, or solutions), and the complexity or number of spectral dimensions for the pulse sequence. The applicability ranges from simple 1D experiments to advanced multiple-pulse and multiple-dimensional experiments, series of simulations, parameter scans, complex data manipulation/visualization, and iterative fitting of simulated to experimental spectra. A major effort has been devoted to optimizing the computation speed using state-of-the-art algorithms for the time-consuming parts of the calculations implemented in the core of the program using the C programming language. Modification and maintenance of the program are facilitated by releasing the program as open source software (General Public License) currently at http://nmr.imsb.au.dk. The general features of the program are demonstrated by numerical simulations of various aspects for REDOR, rotational resonance, DRAMA, DRAWS, HORROR, C7, TEDOR, POST-C7, CW decoupling, TPPM, F-SLG, SLF, SEMA-CP, PISEMA, RFDR, QCPMG-MAS, and MQ-MAS experiments.

Computer software.

While many nurses are aware that the term "software" denotes the programs of instructions by which the computer operates, most of us could probably benefit by knowing more about software basics--what constitutes a program, what constitutes a system, what distinguishes various types of systems, and levels of computer language, and so forth. Few of us are familiar with the types of computer languages in use today. Fewer still realize that the type of language used to program a system has a significant effect on the resources needed to develop and maintain application programs; that specific languages are best used for specific types of applications; or that the amount of flexibility inherent in a specific system depends largely on the language used to program it. This article attempts to inform nurses at the decision-making level about the characteristics of computer software and their implications as criteria for selecting software systems that perform the required functions as efficiently and economically as possible.

Speech therapy after total laryngectomy and esophageal replacement in a preschool patient: a case study.

This case study reports the development of a speech and language therapy program for a preschool boy laryngectomized at age two and three-quarters. Etiology was attributed to the accidental ingestion of lye, which caused severe burns and subsequent damage to both the larynx and esophagus. During the 20-month hospital stay, colon transplantation to the pharynx and laryngectomy were performed and a speech therapy program was initiated. The speech pathologist worked closely with the patient by stimulating his speech and language, developing his articulation skills, and finally providing him with a means of using expressive speech via an electrolarynx designed for him. In addition to the case study, this report reviews the different methods of alaryngeal speech, and suggests the need for further research in developing these methods as viable alternatives for the young laryngectomized child.

Simple recurrent networks learn context-free and context-sensitive languages by counting.

It has been shown that if a recurrent neural network (RNN) learns to process a regular language, one can extract a finite-state machine (FSM) by treating regions of phase-space as FSM states. However, it has also been shown that one can construct an RNN to implement Turing machines by using RNN dynamics as counters. But how does a network learn languages that require counting? Rodriguez, Wiles, and Elman (1999) showed that a simple recurrent network (SRN) can learn to process a simple context-free language (CFL) by counting up and down. This article extends that to show a range of language tasks in which an SRN develops solutions that not only count but also copy and store counting information. In one case, the network stores information like an explicit storage mechanism. In other cases, the network stores information more indirectly in trajectories that are sensitive to slight displacements that depend on context. In this sense, an SRN can learn analog computation as a set of interdependent counters. This demonstrates how SRNs may be an alternative psychological model of language or sequence processing.

A multiuser MUMPS language patient/physician scheduling system for microcomputers.

A microcomputer based patient and physician scheduling system is described that accommodates the special needs unique to residency training programs. Appointments are scheduled automatically according to the type of problems the patient brings to the office as well as the differing time requirements of attending physicians and residents at various levels of training.

Discharge and referral data exchange using global standards--the SCIPHOX project in Germany.

The goal of the German project "Standardization of Communication between Information Systems in Physician Offices and Hospitals using XML" (aka SCIPHOX) in its first phase is to provide information exchange based on the Extended Markup Language XML between Hospital Information Systems (HIS) and Physician Office Systems (POS). The Clinical Document Architecture (CDA), a standard developed by the Health Level Seven organization (HL7), was chosen to serve as the "backbone" specification. The CDA is an ANSI approved document architecture for exchange of clinical information using XML. In phase I of the SCIPHOX project the proposal specifies the use of the CDA as a generalized international standard in the national context of discharge and referral letters in Germany. The specification defines how to use the CDA header and associated vocabularies by providing a translation and interpretation of the CDA header tags and provides a solution for taking local needs (insurance information etc.) into account.

Training generative repertoires within agent-action-object miniature linguistic systems with children.

This study investigated processes responsible for generative language acquisition through the use of a miniature linguistic system. The miniature linguistic system consisted of nonsense syllables and concrete-enactive, agent-action referents. The purpose of Experiment 1 was to determine (a) whether children would recombine agent and action constituents to produce novel utterances and (b) whether children would generate further extensions of the linguistic system (e.g., agent-action-object sentences) following training of a novel syntactic construction. Four children (aged 8:8, 7:4, 4:9, and 4:5) produced novel utterances to describe untrained agent-action referents. They also progressed from agent-action learning to producing agent-action-object sentences after training on only one or two examples of this sentence type with the appropriate referents. Experiment 2 explored conditions more likely to facilitate recombinative generalization among preschoolers. In particular, how a history of lexical learning affects subsequent language learning was investigated with seven 4-year-olds. Results indicated that a history of lexical learning greatly enhanced generative production of untrained agent-action utterances. In addition, all seven children learned new syntactic rules to generate three-word utterances, regardless of the orderings of agent, action, and object words. Implications for developing efficient language remediation programs are discussed.

An infrastructure for Integrated Electronic Health Record services: the role of XML (Extensible Markup Language).

BACKGROUND: The sharing of information resources is generally accepted as the key to substantial improvements in productivity and better quality of care. In addition, due to the greater mobility of the population, national and international healthcare networks are increasingly used to facilitate the sharing of healthcare-related information among the various actors of the field. In the context of HYGEIAnet, the regional health telematics network of Crete, an Integrated Electronic Health Record environment has been developed to provide integrated access to online clinical information, accessible throughout the island. OBJECTIVES: To make available comprehensive medical information about a patient by means of incorporating all the distributed and heterogeneous health record segments into an Integrated Electronic Health Record that can be viewed on-line through a unified user interface and visualization environment. METHODS: The technological approach for implementing this Integrated Electronic Health Record environment is based on the HYGEIAnet Reference Architecture, which provides the necessary framework for the reuse of services, components, and interfaces. Seamless presentation of information is achieved by means of the Extensible Markup Language (XML), while its underlying capabilities allow for dynamic navigation according to personalized end-user preferences and authorities. RESULTS: The Integrated Electronic Health Record environment developed in HYGEIAnet provides the basis for consistent and authenticated access to primary information over the Internet in order to support decision-making. Primary information is always kept at the place where it has been produced, and is maintained by the most appropriate clinical information system, contrasting traditional store and forward techniques, or centralized clinical data repositories. CONCLUSIONS: Since documents are much more easily accessible rather than data inside a database, Extensible Markup Language has the potential of becoming a very cheap technology provided, of course, that the underlying Healthcare Information Infrastructure exists. XML can be introduced incrementally and its implementation is completely transparent to the end user.
