The Mediatisation of professional action: On the necessity of professional competences in the context of digital media in social work

Digitale Medien durchdringen sowohl den Alltag von Adressat/innen als auch die Institutionen und Organisationen Sozialer Arbeit und in der Folge das professionelle Handeln von Fachkräften. Diese Entwicklungen sind vor dem Hintergrund gesellschaftlicher Teilhabe und somit im Kontext individueller Herausforderungen zu betrachten. Um weder den Anschluss an die Lebenswelten ihrer Adressat/innen zu verlieren, noch institutionelle Ausgrenzungsprozesse zu fördern, ist eine Professionalisierung der Sozialen Arbeit im Kontext von digital vernetzten Medien notwendig. Dies erfordert sowohl die Herausbildung von kritischer Medienkompetenz als auch von medienpädagogischen Handlungskompetenzen.Digital Media penetrates the living environment of target groups, institutions and organisations of social work alike. Consequently, it has an impact on professional action. These developments have to be observed in the context of social participation and individual challenges. To neither loose the connection to the living environment of their target groups nor to promote institutional exclusion processes, social work requires a further professionalisation in the media context. This requires both the development of critical media literacy and media education competencies

Types of media education in foster care. : Partial results of a qualitative-reconstructive research.

Mittels des Ansatzes der Dokumentarischen Organisationsforschung geht der Beitrag dem Gegenstand medienerzieherischer Orientierungen in stationären Hilfen zur Erziehung nach. Es wird aufgezeigt, dass organisationale bzw. organisationssoziologische Forschungszugänge und Gegenstandstheorien zu diesem Thema bislang unterrepräsentiert sind und diese einen Beitrag zur medienpädagogischen Forschung leisten können. Dieser wird anhand von Teilergebnissen einer Studie aufgezeigt, konkret an der Rekonstruktion von drei Typen von Medienerziehung in stationären Hilfen zur Erziehung sowie der Relationierung dieser Typen mit weiteren Orientierungsdimensionen im Kontext von Medien und Medienerziehung.Using the approach of documentary organisational research, the article explores the subject of media educational orientations in foster care. It is shown that organisational or organisational-sociological research approaches and theories on this topic have been underrepresented so far and that these can make a contribution to media education research. This will be shown by means of partial results of a study, specifically the reconstruction of three types of media education in foster care and the relation of these types with other orientation dimensions in the context of media and media education

Bioadhesion in the oral cavity and approaches for biofilm management by surface modifications

Background: All soft and solid surface structures in the oral cavity are covered by the acquired pellicle followed by bacterial colonization. This applies for natural structures as well as for restorative or prosthetic materials; the adherent bacterial biofilm is associated among others with the development of caries, periodontal diseases, peri-implantitis, or denture-associated stomatitis. Accordingly, there is a considerable demand for novel materials and coatings that limit and modulate bacterial attachment and/or propagation of microorganisms. Objectives and findings: The present paper depicts the current knowledge on the impact of different physicochemical surface characteristics on bioadsorption in the oral cavity. Furthermore, it was carved out which strategies were developed in dental research and general surface science to inhibit bacterial colonization and to delay biofilm formation by low-fouling or “easy-to-clean” surfaces. These include the modulation of physicochemical properties such as periodic topographies, roughness, surface free energy, or hardness. In recent years, a large emphasis was laid on micro- and nanostructured surfaces and on liquid repellent superhydrophic as well as superhydrophilic interfaces. Materials incorporating mobile or bound nanoparticles promoting bacteriostatic or bacteriotoxic properties were also used. Recently, chemically textured interfaces gained increasing interest and could represent promising solutions for innovative antibioadhesion interfaces. Due to the unique conditions in the oral cavity, mainly in vivo or in situ studies were considered in the review. Conclusion: Despite many promising approaches for modulation of biofilm formation in the oral cavity, the ubiquitous phenomenon of bioadsorption and adhesion pellicle formation in the challenging oral milieu masks surface properties and therewith hampers low-fouling strategies. Clinical relevance: Improved dental materials and surface coatings with easy-to-clean properties have the potential to improve oral health, but extensive and systematic research is required in this field to develop biocompatible and effective substances. © 2020, The Author(s)

Openness als Prinzip von Organisationsentwicklung. Werkbericht zu partizipationsorientierten Dialogformaten im Projekt OERlabs

Ziel des BMBF-Projekts OERlabs war es, einen Kulturwandel in Lehre und Forschung hin zu offenen Praktiken anzustoßen. Hierfür wurden Akteurinnen/Akteure entlang der Lehrer*innenbildungskette im Rahmen von Multi-Stakeholder-Dialogen selbst mit offenen Bildungspraktiken konfrontiert, um partizipatorisch Herausforderungen und Lösungen für die Implementation von OER (Open Educational Resources) an der Hochschule (bzw. der Lehrer*innenbildung) zu be- und erarbeiten. Der folgende Werkstattbericht beschreibt die Potenziale von Open Education für organisationales Lernen sowie die Implementierung offener Bildungspraktiken im Rahmen von Dialogformaten

Prerogative of interpretation: Digitisation and education in programmes and funding guidelines of Germany and the EU

Der vorliegende Beitrag befasst sich mit diskurs- und machtpolitisch hervorgerufenen Deutungshoheiten in Bezug auf Forschung zu und über Digitalisierung und Bildung in Programmatiken und Förderrichtlinien Deutschlands und der EU. Er gründet auf der Annahme, dass Forschungs- und Wissenschaftssysteme seit geraumer Zeit in enger Abhängigkeit zu Förderprogrammen stehen, welche auf unterschiedlichen politischen Ebenen als so genannte Förderinstrumente diverser Bildungsbereiche und der Wissenschaft selbst fungieren (sollen). Bei empirischer Betrachtung werden Deutungshoheiten infolge dieser Hinwendung zu und gleichzeitigen Abwendung von Begriffen und Konzepten sichtbar – nicht nur im Zusammenhang mit Diskursen um Digitalisierung und Bildung. Folge sind die (Über-)Betonung einzelner Konzepte und die zurückhaltende Repräsentation anderer, was für die Medienpädagogik qualifikatorische Engfassungen bedeutet, die auf empirischer Basis sowie vor dem Hintergrund präsenter Konzepte zu zeigen sind.This article is concerned with the prerogative of interpretation in relation to digitisation and education in the programmes and funding guidelines of Germany and the EU that has been created by political discourse and power. It is based on the assumption that the research and science system have for some time been closely dependent on funding programmes, which (should) function at different political levels as so-called funding instruments of various educational sectors and of science itself. On empirical observation, this turning towards and simultaneous rejection of terms and concepts makes prerogative of interpretation visible - not only in connection with discourses on digitisation and education. The consequence is the (over-)emphasis on individual concepts and the restrained representation of others, which means qualification narrowness for media education, which must be shown on an empirical basis and against the background of present concepts

Bioadhesion on Textured Interfaces in the Human Oral Cavity—An In Situ Study

Extensive biofilm formation on materials used in restorative dentistry is a common reason for their failure and the development of oral diseases like peri-implantitis or secondary caries. Therefore, novel materials and strategies that result in reduced biofouling capacities are urgently sought. Previous research suggests that surface structures in the range of bacterial cell sizes seem to be a promising approach to modulate bacterial adhesion and biofilm formation. Here we investigated bioadhesion within the oral cavity on a low surface energy material (perfluorpolyether) with different texture types (line-, hole-, pillar-like), feature sizes in a range from 0.7–4.5 µm and graded distances (0.7–130.5 µm). As a model system, the materials were fixed on splints and exposed to the oral cavity. We analyzed the enzymatic activity of amylase and lysozyme, pellicle formation, and bacterial colonization after 8 h intraoral exposure. In opposite to in vitro experiments, these in situ experiments revealed no clear signs of altered bacterial surface colonization regarding structure dimensions and texture types compared to unstructured substrates or natural enamel. In part, there seemed to be a decreasing trend of adherent cells with increasing periodicities and structure sizes, but this pattern was weak and irregular. Pellicle formation took place on all substrates in an unaltered manner. However, pellicle formation was most pronounced within recessed areas thereby partially masking the three-dimensional character of the surfaces. As the natural pellicle layer is obviously the most dominant prerequisite for bacterial adhesion, colonization in the oral environment cannot be easily controlled by structural means

A new animal model for delayed osseous union secondary to osteitis

Background: The treatment of infection-related delayed bone unions is still very challenging for the orthopedic surgeon. The prevalence of such infection-related types of osteitis is high in complex fractures, particularly in open fractures with extensive soft-tissue damage. The aim of this study was to develop a new animal model for delayed union due to osteitis. Methods. After randomization to infected or non-infected groups 20 Sprague–Dawley rats underwent a transverse fracture of the midshaft tibia. After intramedullary inoculation with staphylococcus aureus (103 CFU) fracture stabilization was done by intramedullary titanium K-wires. After 5 weeks all rats were euthanized and underwent biomechanical testing to evaluate bone consolidation or delayed union, respectively. Micro-CT scans were additionally used to quantitatively evaluate the callus formation by the score of Lane and Sandhu. Blood samples were taken to analyze infectious disease markers (day 1, 14 and 35). Results: Biomechanical testing showed a significant higher maximum torque in the non-infected group 5 weeks postoperatively compared with the infected group (p < 0.001). According to the Lane and Sandhu score a significantly higher callus formation was found in the non-infected group (p < 0.001). Similarly, the leucocyte count in the infected group was significantly higher than in the non-infected group (p < 0.05). Conclusions: Here we have established a new animal model for delayed osseous union secondary to osteitis. The animal model appears to be appropriate for future experimental studies to test new therapeutic strategies in these difficult to treat bone healing complications
