The paper aims to investigate the link between models and system results. It looks at fundamental principles underlying social activities and strives to understand the logical role of models in social governing. Based on these a heuristic is assembled enabling the recognition of the specific contribution formal models can provide for social contexts and also for recognizing the limitations that apply.

The heuristic is developed based on first principles of systems theory and cybernetics with particular consideration of managerial cybernetics. It starts with the assumption that human cognition roots in an autopoietic process from which individual “realities” and Weltanschauungen evolve. Interaction then leads human actors to adopt social system notions through which they initiate and constantly reconcile the implementation of their commonly aspired purposes. With system structures, it is referred to how actors relate to each other in governing – which is a key to learning about what models can contribute. Therefore, the concept of system structure is derived from interaction and rooted in the social system notion distinguishing aspects of structural capacity that pre‐condition the implementation of desired social outcomes. Subsequently, a logical anatomy of system notions is revealed and expressed with a set of invariant systemic topics necessary when being addressed in governing.

The paper finds a heuristic for identifying the contribution formal models provide to the governance of social systems and recognition of the benefits and limitations specific models provide to governing. Conclusions are drawn on the pre‐conditions securing sustained organizational development through the application of formal models.

The heuristic assembled in this paper facilitates the harmonization and alignment of models in governance settings. The recognition of the role of models in social governing is identified as a logical pre‐condition of sustainable governance. The heuristic presented facilitates assessing and optimizing governing structures with respect to those pre‐conditions.

A central question of governance in our time is how actors in complex, diverse and dynamic contexts can be harmonized, respecting the needs and limitations of their contexts. New technologies enable shaping and modelling interactions to an extent hitherto unknown. They constitute a huge potential to support and integrate interactions and to reshape governance. This paper sets out to explore a concept of interaction applicable to media which captures and addresses the specific characteristics of social systems required to ensure their viability.

The potential of cybernetics and systems theory for both the design and application of media in social contexts is explored. Building on an autopoietic concept of social systems, a notion of governance as a process of interaction is established. Beer's Viable Systems Model (VSM) and Schwaninger's Model of Systemic Control is applied to derive the characteristic elements, configurations and types of interaction required to support balancing actors' images in social systems. Links to political and social science theory are provided.

Cybernetic and system theories provide a solid conceptual basis for capturing the complexity, dynamics and diversity of interaction. Identifying and addressing the relevant characteristics of interaction in social systems can be achieved through the application of cybernetic tools and vocabulary. These can be used to specify and secure the necessary and sufficient design principles for media through which the viability of social systems can be promoted.

The paper shows that requirements to the structure of media applied in social contexts can be specified. Analysing interactions in all kind of social systems does provide clues for the development, implementation, and configuration of improved media. When applied properly, these can boost up governing interactions to much more productive and sustainable forms. This turns out to be a remarkable opportunity to promote the governance of social systems.

Time reduction and quick geometrical changes of complex components and tools are currently the most important demands in product development. The manufacturing process presented in this paper is based on multiple additive and subtractive technologies such as laser cutting, laser welding, direct laser metal deposition and CNC milling. The process chain is similar to layer‐based Rapid Prototyping Techniques. In the first step, the 3D CAD geometry is sliced into layers by a specially developed software. These slices are cut by high speed laser cutting and then joined together. In this way laminated tools or parts are built. To improve surface quality and to increase wear resistance a CNC machining center is used. The system consists of a CNC milling machine, in which a 3 kW Nd:YAG laser, a coaxial powder nozzle and a digitizing system are integrated.

“All things are in a constant state of change”, said Heraclitus of Ephesus. The waters if a river are for ever changing yet the river endures. Every particle of matter is in continual movement. All death is birth in a new form, all birth the death of the previous form. The seasons come and go. The myth of our own John Barleycorn, buried in the ground, yet resurrected in the Spring, has close parallels with the fertility rites of Greece and the Near East such as those of Hyacinthas, Hylas, Adonis and Dionysus, of Osiris the Egyptian deity, and Mondamin the Red Indian maize‐god. Indeed, the ritual and myth of Attis, born of a virgin, killed and resurrected on the third day, undoubtedly had a strong influence on Christianity.

In this study the authors use longitudinal data from a randomized experiment to investigate the impact of a feedback and coaching intervention on principals’ leadership behaviors. The paper aims to discuss these issues.

In total, 52 elementary and middle school principals (26 receiving teacher feedback, 26 receiving feedback and coaching) were randomized into a year-long feedback and coaching study. Measures of leadership actions were collected from principals and teachers during the fall, winter, and spring. The authors use instrumental variables approach to examine the impact of treatment.

Behavioral change may take longer than is presented in this study, which implies that these findings represent a lower-bound. As an intervention leadership coaching is costly and this research does not explore alternatives to help principals make feedback data actionable.

It is unlikely that providing school leaders with feedback alone will induce behavioral change. Other systems and supports – such as leadership coaching – are needed to help principals make sense of feedback data and translate data into actionable behaviors.

Few leadership studies use exogenous variation in treatment conditions to examine leadership outcomes. This study builds upon our causal knowledge of leadership behaviors and presents a viable intervention to improve school leadership.

Examines the fifthteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.
