Eine exemplarische Analyse der Lernbegründungen von TeilnehmerInnen an Mediationsprozessen

Mit dem Konzept des Lebenslangen Lernens erfährt die Erwachsenenbildung eine Neu-ausrichtung. Der traditionelle Fokus auf formalisierte Lehr-/Lernprozesse wird um informelle und nicht formale Lehr-/Lernformen erweitert. (vgl. Beschluss der Kultusministerkonferenz 2001, S. 3-4). Für den Lernprozess von Erwachsenen bedeutet dies, dass neuere Formen pädagogischen Handelns an Relevanz gewinnen. In der vorliegenden Arbeit wird Mediation als besondere Art der pädagogischen Grundform der Beratung (Glenewinkel & Kraft 2017, S. 512) unter erwachsenenpädagogischer Perspektive erstmalig untersucht und somit der wissenschaftliche Versuch unternommen, den pädagogischen Blickwinkel auf den Forschungsgegenstand Mediation zu konturieren. Dabei wird der Fragestellung nachgegangen, warum Menschen sich für die Teilnahme an Mediationsprozessen entscheiden. In Abwägung verschiedener lerntheoretischer Zugänge findet die Forschungsfrage Anschluss in den kulturellen und gesellschaftlich geprägten Möglichkeitsräumen und den subjektiven Handlungsbegründungen der subjektwissenschaftlichen Lerntheorie Holzkamps. In dieser wird Mediation als Lernprozess eingeordnet und empirisch untersucht, welche sich angesichts des explorativen Charakters am Paradigma der qualitativen Sozialforschung orientiert. Es werden drei halbstrukturierte, erzählgenerierende Interviews mit Teilnehmenden an Mediationsprozesse geführt und in Anlehnung an den zuvor abgesteckten theoretischen Bezugsrahmen deduktiv-induktiv ausgewertet

Gift: an integrated development and training system for finite state machine based approaches

At the Ilmenau University of Technology’s “Integrated Communication Systems” Department a main teaching concept deals with the design of digital control systems. Different lectures from the 1st to the 8th semester are using Finite State Machines (FSM) as a specification technique to realize different design tasks. During undergraduate studies the basics of Finite State Machines and their usage within the design of digital control systems are taught. To conceptualize more complex digital systems, as required in higher courses, it is necessary to use powerful toolsets. One example of such a toolset is the GIFT (Graphical Interactive Finite State Machine Toolset) system, developed by the Integrated Communications System Group at the Ilmenau University of Technology. With this toolset we want to extent our remote lab GOLDi and implement new techniques for a web-based development system for Finite State Machines

Basic functionality of a prototype wearable assistive soft exoskeleton for people with gait impairments : a case study

XoSoft is a soft modular wearable assistive exoskeleton for peo- ple with mild to moderate gait impairments. It is currently being developed by a European Consortium (www.xosoft.eu) and aims to provide tailored and active lower limb support during ambu- lation. During development, user-centered design principles were followed in parallel with the aim of providing functional support during gait. A prototype was developed and was tested for practi- cability, usability, comfort and assistive function (summarized as basic functionality) with a potential end user. The prototype con- sisted of a garment, electromagnetic clutch-controlled elastic bands supporting knee- and hip flexion and a backpack containing the sensor and actuator control of the system. The participant had ex- perienced a stroke and presented with unilateral impairment of the lower and upper extremities. In testing, he donned and doffed the prototype independently as far as possible, and performed walk- ing trials with the system in both active (powered on) and pas- sive (powered off) modes. Afterwards, the participant rated the perceived pressure and various elements of usability. Results high- lighted aspects of the system for improvement during future phases of XoSoft development, and also identified useful aspects of proto- type design to be maintained. The basic functionality of XoSoft could be assumed as satisfactory given that it was the first version of a working prototype. The study highlights the benefits of this participatory evaluation design approach in assistive soft robotics development

Autonomous unmanned ground vehicle as sensor carrier for agricultural survey tasks

For agricultural surveys, the use of unmanned ground vehicles (UGV) as sensor carriers is becoming increasingly attractive. These vehicles can be equipped with multiple sensing de-vices to achieve a high level of autonomy in order to improve productivity and profitability in agriculture. For this application, special requirements for the UGV must be fulfilled. The system presented in this paper is designed to adapt to the plant row spacing in an orchard with a flexible track width of between 0.8 and 1.2 meters. It uses 29-inch wheels to provide a ground clearance of at least 40 centimetres. The payload (sensor platform) is fully separated from the driving unit and will be provided with electric power from the battery. The four wheels are each equipped with electric motors. A hinged axle enables a small turning radius for the transfer from one leg of the survey to the next. First tests with the UGV show stable steering characteristics and sufficient power for up-hill motion. The arrangement of a sensor head with multiple sensors for environmental modelling and navigation, as well as the realisation of a hard real-time control system for the drivetrain and sensors results in this concept study being a very challenging task

Unconscious relational encoding depends on hippocampus

Textbooks divide between human memory systems based on consciousness. Hippocampus is thought to support only conscious encoding, while neocortex supports both conscious and unconscious encoding. We tested whether processing modes, not consciousness, divide between memory systems in three neuroimaging experiments with 11 amnesic patients (mean age = 45.55 years, standard deviation = 8.74, range = 23-60) and 11 matched healthy control subjects. Examined processing modes were single item versus relational encoding with only relational encoding hypothesized to depend on hippocampus. Participants encoded and later retrieved either single words or new relations between words. Consciousness of encoding was excluded by subliminal (invisible) word presentation. Amnesic patients and controls performed equally well on the single item task activating prefrontal cortex. But only the controls succeeded on the relational task activating the hippocampus, while amnesic patients failed as a group. Hence, unconscious relational encoding, but not unconscious single item encoding, depended on hippocampus. Yet, three patients performed normally on unconscious relational encoding in spite of amnesia capitalizing on spared hippocampal tissue and connections to language cortex. This pattern of results suggests that processing modes divide between memory systems, while consciousness divides between levels of function within a memory system
