Hierarchies and Universal Inclusion in Scientific Communities

This chapter explains the genesis of inequalities and hierarchies in modern science. It studies the forms and mechanisms of scientific communication on the basis of which the social structures of science are built: publications, authorship, co- and multiple authorship, citations as units of information and as social rewards, peer review as evaluation of publications (and of projects and careers). This is a network of institutions that seems to guarantee universal access to participation in science to all those who fulfill basic conditions. But the chapter demonstrates how in all these institutional dimensions differences arise between successful and not equally successful participations. Success generates influence and social attractiveness (e.g. as a co-author). Influential and attractive participants are recruited into positions where they assess the achievements of others and thereby limit and control inclusion in publications, funding and careers. Equality at the start is transformed into hierarchies of control. Finally, the chapter asks for potential alternative control structures that transform a conservative hierarchy into decentralized ‘market’ controls that involve everyone in a more dynamic production and evaluation of scientific achievements.

A Hypergraph Model for Communication Patterns

The article deals with interaction in concurrent systems. A calculus able to express specific communication patterns is defined, together with its abstract control structures. A hypergraph model for these structures is presented. The hypergraphs are able to properly express the communication patterns, providing a fully abstract model for the pattern calculus. It is also proved that the hypergraph model preserves the operational reductions of processes from pattern calculus and of the actions from the control structures.

Implementation of PI and MPC-Based Speed Controllers for a Drive with Elastic Coupling on a PLC Controller

This paper presents some of the issues related to the implementation of advanced control structures (PI controller with additional feedback, Model Predictive Controller) for drives with elastic coupling on a programmable logic controller (PLC). The predominant solutions to electric drive control include the use of rapid prototyping cards, signal processors or programmable matrices. Originally, PLC controllers were used to automate sequential processes, but for several years now, a trend related to their implementation for advanced control objects can be observed. This is mainly due to their compact design, immunity to disturbances and standard programming languages. The following chapters of the paper present the mathematical model of the drive and describe the implementation of the proposed control structures. A PI controller with additional feedback loops and a predictive controller are taken into consideration. Their impact on the CPU load was analysed, and the work was summarised by a comprehensive experimental study. The presented results confirm that it is possible to implement advanced control structures on a PLC controller for drives with elastic coupling while maintaining a sufficiently low load on its CPU.

Islands of Deliberative Capacity in an Ocean of Authoritarian Control? The Deliberative Potential of Self-Organised Teams in Firms

Business firms play an increasingly influential role in contemporary societies, which has led many scholars to return to the question of the democratisation of corporate governance. However, the possibility of democratic deliberation within firms has received only marginal attention in the current debate. This article fills this gap in the literature by making a normative case for democratic deliberation at the workplace and empirically assessing the deliberative capacity of self-organised teams within business firms. It is based on sixteen in-depth interviews in six German firms which practice various forms of self-organised teamwork. The article argues that self-organised teamwork can create a space for authentic, inclusive, and consequential deliberation by suspending authoritarian control structures within business firms. Finally, the article proposes the consideration of firms not only as necessary parts of a larger deliberative system but also as deliberative systems in themselves.

Evaluation and Enhancement of Sustainable Organic Fishpond Farming in the Sei Teras Fishpond Irigation Area, Central Kalimantan

Sei Teras fishpond area was developed by the Banjar community in 2006. The conditions of the ponds in Sei Teras are still very simple, where the availability of seeds and feed is completely dependent on nature. The evaluation is based on the level of control and the production rate, while efforts for improvement are planned through controlling water quality. In the rainy season, the shrimp productivity ranges from 180 Kg/ha, while it can reach 450 kg/ha in the dry season. From the measurements results in November 2020-Mei 2021, it was noted that the salinity of the water in fishponds and canals ranged from 2 to 24.3 ppt while the water pH ranged from 6.11. to 7.87. Water quality parameters such as DO and pH have met the criteria for applying higher aquaculture technology, while other parameters such as Nitrate, Nitrite, Ammonia, TDS and Salinity require improvement and/or control. An alternative design is in the form of rearranging the fishpond system such as individual fishpond size. In addition, it is necessary to manage the fishpond irrigation network, namely by planning the main control structures separating fresh water and saline water, and rehabilitation of channels that experience sedimentation.

Fundamental review of the trading book - Stato dell’arte sulle implementazioni dell’Internal Model Approach

In light of the finalization of the new regulatory framework for market with the adoption of the FRTB at EU level through the publication of CRR III, financial institutions are consolidating the implementations aimed to comply with the new regulatory requirements. The main purpose of this article is to analyze how banks are preparing for the go-live of IMA FRTB reporting – expected to be in January 2024 – focusing on the challenges that they are facing especially in terms of model transformations. In particular, an in-depth analysis will be carried out on the main methodological issues of the new regulatory context technicalities,in order to provide guidelines and market best practices on the Internal Model Approach (IMA) topics shared between Front Office, Risk Management as well as Control Structures.
