ReSpecTX: Programming interaction made easy

In this paper we present the ReSpecTX language, toolchain, and standard library as a first step of a path aimed at closing the gap between coordination languages ? mostly a prerogative of the academic realm until now ? and their industrial counterparts. Since the limited adoption of coordination languages within the industrial realm is also due to the lack of suitable toolchains and libraries of reusable mechanisms, ReSpecTX equips a core coordination language (ReSpecT) with tools and features commonly found in mainstream programming languages. In particular, ReSpecTX makes it possible to provide a reference library of reusable and composable interaction patterns.

The Cost and Benefits of Coordination Programming: Two Case Studies in Concurrent Collections and S-NET

This is an evaluation study of the expressiveness provided and the performance delivered by the coordination language S-NET in comparison to Intel’s Concurrent Collections (CnC). An S-NET application is a network of black-box compute components connected through anonymous data streams, with the standard input and output streams linking the application to the environment. Our case study is based on two applications: a face detection algorithm implemented as a pipeline of feature classifiers and a numerical algorithm from the linear algebra domain, namely Cholesky decomposition. The selected applications are representative and have been selected by Intel researchers as evaluation testbeds for CnC in the past. We implement various versions of both algorithms in S-NET and compare them with equivalent CnC implementations, both with and without tuning, previously published by the CnC community. Our experiments on a large-scale server system demonstrate that S-Net delivers very similar scalability and absolute performance on the studied examples as tuned CnC codes do, even without specific tuning. At the same time, S-Net does achieve a much more complete separation of concerns between compute and coordination layers than CnC even intends to.

Possibilities of Elementary Musical Lessons for Children Communication Skills

Object of the paper - explore the possibilities of musical lesson for the child for communication skills. The paper was used for theoretical metod - analysis of scientific literature and empirical research method – pedagogical observations of individual and group lessons. Theoretically and practically explored and described possibilities of music lessons for communication skills. The author main conclusions of the study: 1. By participating in the musical play, children are encouraged musical hearing, physical coordination, language development, emotional and social development, communication and independence skills, etc. 2. When creating classesmodels to integrate all the musical creativity components (singing, musical hearing, instrument performance, listening to music and musical play) according to the child’s level of development, which is found in the cooperation process. Then the children are motivated to participate in their own musical improvisations through which benefits their musical development and communication skills. 3. Working in the music developed models child learn new characters and concepts, learn to listen and rely on emotional song with likes and dislikes, developing musical and timbral hearing, and the metro rhythm. It also contributes to thinking, imagination, language development, speech understanding, communication skills, physical coordination, ability to independently develop creative musical improvisation, and gradually formed the experience of the music world.

Carving language for social coordination

Human social coordination is often mediated by language. Through verbal dialogue, people direct each other’s attention to properties of their shared environment, they discuss how to jointly solve problems, share their introspections, and distribute roles and assignments. In this article, we propose a dynamical framework for the study of the coordinative role of language. Based on a review of a number of recent experimental studies, we argue that shared symbolic patterns emerge and stabilize through a process of local reciprocal linguistic alignment. Such patterns in turn come to facilitate and refine social coordination by enabling the alignment, joint construction and navigation of conceptual models and actions. Implications of the framework are illustrated and discussed in relation to a case study where dyads of interlocutors interact verbally to reach joint decisions in a perceptual discrimination task.
