This paper aims to clarify the meaning of children’s participation in the relationship between children’s individual action and the social treatment and consequences of this action. For this purpose, the paper explores the integration of different theoretical approaches that can shape research on children’s participation, looking at interactions, complex social systems that include interactions, and narratives that are produced in these complex social systems. This integration allows the understanding of the ways in which children actively participate in communication processes, social structures condition children’s active participation, and children’s active participation can enhance structural change in social systems, through the implementation of promotional communication systems. The paper highlights the following paradox: the relevance of children’s action for social change depends on the relevance of adults’ action in promoting children’s actions. This theoretical perspective is exemplified in the case of promotion of children’s active participation in the education system through the empirical analysis of cases of videotaped and transcribed interactions, highlighting facilitation systems of classroom communication. The analyzed data are based on a field research in Italian classrooms regarding a specific methodology of facilitation of communication. The analysis of these data shows the ways in which the facilitation system creates the paradoxical relationship between structures that condition children’s active participation and children’s active participation that enhances structural change. The paper highlights a new way of dealing with children’s participation, based on a social constructionist, systemic, and interactionist approach.

The purpose of this paper is to explain the US society’s insignificant mitigation of climate change using Niklas Luhmann’s (1989) autopoietic social systems theory in ecological communication. Specifically, the author’s analysis falls within the context of Luhmann re-moralized while focusing on particular function systems’ binary codes and their repellence of substantive US climate change mitigation policy across systems.

The author achieves this purpose by resituating Luhmann’s conception of evolution to forgo systems teleology and better contextualize the spatial-temporal scale of climate change; reinforcing complexity reduction and differentiation by integrating communication and media scholar John D. Peters’s (1999) “communication chasm” concept as one mechanism through which codes sustain over time; and applying these integrated concepts to prominent the US climate change mitigation attempts.

The author concludes that climate change mitigation efforts are the amalgamation of the systems’ moral communications. Mitigation efforts have relegated themselves to subsystems of the ten major systems given the polarizing nature of their predominant care/harm moral binary. Communication chasms persist because these moral communications cannot both adhere to the systems’ binary codes and communicate the climate crisis’s urgency. The more time that passes, the more codes force mitigation organizations, activist efforts and their moral communications to adapt and sacrifice their actions to align with the encircling systems’ code.

In addition to the conceptual contribution, the social implication is that by identifying how and why climate change mitigation efforts are subsumed by the larger systems and their codes, climate change activists and practitioners can better tool their tactics to change the codes at the heart of the systems if serious and substantive climate change mitigation is to prevail.

To the author’s knowledge, there has not been an integration of a historical communication concept into, and sociological application of, ecological communication in the context of climate change mitigation.

The purpose of this article is to show the foundational place that communication theory and its practice occupies in functioning work systems.

This paper defines the word communication in terms of the creation and interpretation of displays, describes what it means to have a theoretical foundation for a discipline, identifies and elaborates on the development driving force of human resource development (HRD), presents and explains a model of a work system in which HRD functions, and elaborates on the role, function, and place of communicative acts in the maintenance of the work system and the work of HRD professionals.

The article posits that communication theory underlies the processes and activities of both scholars and practitioners of HRD. Finally, it argues that courses in communication theory and organizational communication are essential in the preparation of both scholars and practitioners.

Research on the vagaries of communication in work systems may need to focus on identifying the causes of more easily identified symptoms. Researchers must be constantly alert to the changing role of communication as both a symptom and a cause of effective and ineffective work system functioning.

Since human resource development is applied, practiced, and used predominantly in work systems, sensitivity to the fundamental role that communication plays in work systems may allow HRD practitioners to take a communicative perspective in analyzing and solving problems.

This article directs readers to the main, fundamental issue in organizations and highlights the central role of communication in the functioning and development of both the human resources and the work system.

During the service period of communication satellite systems, their performance is often degraded due to the depletion mechanism. In this paper, the grey system theory is applied to the multi-state system effectiveness evaluation and the grey Lz-transformation ADC (availability, dependability and capability) effectiveness evaluation model is constructed to address the characteristics of the communication satellite system such as different constituent subsystems, numerous states and the inaccuracy and insufficiency of data.

The model is based on the ADC effectiveness evaluation method, combined with the Lz transformation and uses the definite weighted function of the three-parameter interval grey number as a bridge to incorporate the possibility of system performance being greater than the task demand into the effectiveness solution algorithm. At the same time, using MATLAB (Matrix laboratory) to solve each state probability, the same performance level in the Lz transform is combined. Then, the system effectiveness is obtained by Python.

The results show that the G-Lz-ADC model constructed in this paper can accurately evaluate the effectiveness of static/dynamic systems and certain/uncertain system and also has better applicability in evaluating the effectiveness of the multi-state complex system.

The G-Lz-ADC effectiveness evaluation model constructed in this paper can effectively reduce the complexity of traditional effectiveness evaluation models by combining the same performance levels in the Lz-transform and solving the effectiveness of the system with the help of computer programming, providing a new method for the effectiveness evaluation of the complex MSS. At the same time, the weaknesses of the system can be identified, providing a theoretical basis for improving the system’s effectiveness.

The possibility solution method based on the definite weighted function comparing the two three-parameter interval grey numbers is constructed, which compensates for the traditional calculation of the probability based on numerical values and subjective preferences of decision-makers. Meanwhile, the effectiveness evaluation model integrates the basic theories of three-parameter interval grey number and its definite weighted function, Grey−Markov, grey universal generating function (GUGF), grey multi-state system (GMSS), etc., which is an innovative method to solve the effectiveness of a multi-state instantaneous communication satellite system.

The links between moral communication and legal communication have long been studied in sociology of law. Little has yet been said about moral communication invoking when communication in the legal system is impossible, ineffective or uncertain. The paper fills this gap to demonstrate that systems theory-based sociology of law can effectively recognise the role of moral communication in such situations.

The paper presents an empirical study of moral communication in small and medium-sized enterprises (SMEs). It focused on situations when SMEs' interactions with function systems, particularly the legal system, result in irremovable legal uncertainty. The data depict strategies of managing such uncertainty and were obtained in a paths-to-justice survey of 7,292 owners and managers of SMEs and 101 in-depth interviews. The findings are interpreted using the author's concept of “uncertainty translation”, rooted in Luhmann's systems theory. It suggests that business organisations such as SMEs deal with the ubiquitous uncertainty in their operations by translating it into a convenient type.

The study distinguishes between formative and absorbing moral communication and finds that both types play a role in steering the uncertainty translation mechanism in SMEs. Six scenarios of invoking moral communication are identified in SMEs dealing with legal uncertainty. In such scenarios, moral communication facilitates the translation of business uncertainty “away from law”. Under some circumstances, this, in turn, leads to latent systematic results, reflexively affecting the legal system, the economic system and the SMEs.

In its core argument, the study is based on qualitative material. While it identifies empirical scenarios of invoking moral communication, it does not report the prevalence of these scenarios due to methodological limitations.

The study results pose questions related to the staple theoretical issue in post-Luhmannian social systems theory: functional differentiation. If moral communication–a type of communication not linked to any social system–can produce far-reaching, systematic results that affect function systems, then the functional differentiation thesis should be less pronounced than Luhmann typically stressed. This said, the paper argues that the contradiction between the findings and Luhmannian theory of morality is only apparent and may be reconciled.

This paper aims to analyze the key factors influencing the synchronization performance of distributed motion control system and to improve the synchronization performance for peripherals control of this system.

This paper deals with the software synchronization problems of distributed motion control system based on real-time Ethernet. First, combined with communication and control tasks, the key factors affecting synchronization performance of system are analyzed. Then, aiming at key factors and considering the synchronization of system bus, protocol conversion and task scheduling, a software synchronization method based on CANopen protocol and real-time Ethernet is proposed. Finally, the feasibility of this method is verified by establishing distributed motion control system and testing the synchronization performance of terminal control signals of slaves.

Based on this method, the results show that the synchronization accuracy for peripherals control of all slaves could be about 100 ns.

This research provides high-precision synchronization method, which could lay a foundation for the application of distributed motion control system in the field of assembly automation, such as multi-axis assembly robots control.

In distributed motion control system, many factors affect the synchronization performance. At present, there is no synchronization method that could comprehensively consider these factors. This paper not only analyzes the key factors influencing the synchronization performance of system but also proposes a synchronization method. Therefore, the method proposed in this paper has certain theoretical value and engineering significance.

Many recent studies have voiced the growing concern that the body of knowledge that springs from organization science is hardly taken notice of in management practice. This has given rise to urgent calls for making organization research more relevant to practitioners and an intensive debate on how to realize this aim has set in (e.g., Hodgkinson, Herriot, & Anderson, 2001; Rynes, Bartunek, & Daft, 2001; MacLean & MacIntosh, 2002; Baldridge, Floyd, & Markoczy, 2004; Van de Ven & Johnson, 2006). In most of the existing literature one can identify three main reasons for the observable lack of connection between organization research and practice: research is not sufficiently focused on the “real” problems of practitioners (e.g., Rynes, McNatt, & Breetz, 1999), research results are not properly disseminated to practitioners (e.g., Spencer, 2001), and the language of science is not properly translated into the language practitioners' use (e.g., Starkey & Madan, 2001; Van de Ven & Johnson, 2006). The underlying assumption is that if scientists redressed these shortcomings, their findings would be utilized by practitioners and thus the gap between theory and practice would be bridged.

Given the rise of individuals who have complex communication needs (CCN), it is important to identify appropriate assistive technology systems that can support the individual's communication needs. Augmentative and alternative communication (AAC) systems can serve as a means to assist individuals to communicate independently. The goal of AAC is to enhance or replace the individual's current and limited verbal or written communication skills. This chapter focuses on feature matching, aided communication and the selection process for aided communication systems including low to high technology systems. It also emphasises other key considerations pertaining to person-centred planning such as conducting preference assessments and trial periods to minimise system abandonment.

Drawing from the work of sociologist Niklas Luhmann, this paper analyzes and critiques the ways sociology presents itself as a vehicle for sociological “enlightenment.” It begins with a brief historical account of how sociology has come to describe itself as a science in the name of promoting social justice rooted back to the European Enlightenment of the eighteenth century. Next, the relevant elements of Luhmann's theory of society are explained ground the analysis. Luhmann's critiques of sociology and science are then presented to explain how a Luhmannian understanding of social systems exposes what is missing in sociology's current self-description of itself and its “enlightenment” mission. Building upon Luhmann's observations, a preliminary observational analysis of the communication techniques and technologies of sociology, such as classes, conferences, and publications, is assessed to evaluate the tools sociology uses to engage in communication and “irritate” other social systems. The central question here is, are these tools effective in communicating sociological knowledge in a way that aligns with the aspirational humanistic goals sociology seeks to achieve? The argument then concludes with some remarks about how sociology might potentially overcome its communicative efficacy problem if it takes seriously the insights from a Luhmannian approach to communication and considers alternative forms of communication to reach new audiences. In this way, sociology could perhaps overcome the gap between the facts of its communicational efficacy and its enlightenment norms.
