Werkstattbericht zum Projekt NAHGast, Fokus: ‚Leitbild nachhaltiger Gemeinschaftsverpflegung‘
(2016)
Kugelstrahlen ist ein im Maschinenbau eingesetztes Verfahren zur Steigerung der Ermüdungsfestigkeit. Es wird z. B. bei hochbelasteten Komponenten in der Luft- und Raumfahrt, der Fahrzeugtechnik, im Turbomaschinenbau und weiteren Industriezweigen angewandt. Die Einstellung der Betriebsparameter der Kugelstrahlanalage findet üblicherweise mit kostenintensiven empirischen Versuchen statt, mit dem Ziel, die vorgegebene Druckeigenspannung zu erreichen. In [1, 2] wird auf der Basis einer dort beschriebenen neuartigen Elementarzelle vorgeschlagen, die Almenstreifenaufbiegung als Mittel zur Spezifikation der Verfestigung heranzuziehen. Dazu ist deren Simulation notwendig, welche sich mit der entwickelten Elementarzelle wirtschaftlich bewerkstelligen lässt. In der hier vorliegenden Veröffentlichung werden die der Elementarzelle zugrundeliegenden Finite-Elemente-Netze (FE-Netze) mithilfe von Einzelbe-schussversuchen validiert. Weiterhin wird eine ähnlichkeitsmechanische Betrachtung des Kugelstrahlprozesses zur vereinfachten Parametereinstellung vorgestellt.
This paper introduces and empirically illustrates a pedagogical approach to teaching Public Relations (PR) in higher education. The approach is based on the Communities of Practice theory (Wenger, 1998). Based on this theory and for the purposes of this paper, learning is perceived as (1) a participation in a practice of (2) a social community and (3) the understanding of this practice. The pedagogical approach to teaching PR entails the facilitation of these three elements. The approach is illustrated through a case study. The authors conducted an international undergraduate course to teach students how to conduct a social media campaign to raise engagement for social issues. Twenty students from Netherlands and Germany enrolled. The paper offers an integrated understanding of theory and practice (see Wenger, 1998, p. 48). It contrasts many current approaches in PR education, which tend to differentiate between PR theory and practice. PR educators are encouraged to facilitate an equal negotiation between theory and practice and to enable students to match whatever is theorised with practice and whatever is practiced with theory.
Talent scarcity in emerging economies such as India poses challenges for companies. Limited labour market participation among well-educated women has been observed. The reasons that professionals decide not to pursue a further corporate career remain unclear. By investigating their career decision making, this handout summerizes research results from a study that aims to highlight the contextual factors that impact those decisions.
Following a qualitative research design interviews with internationally experienced Indian business professionals show that rebellion against Indian societal and family expectations is essential to following a career path, especially for women. The current institutional framework of society and organizations serves as a legitimizing façade veiling traditional practices that hinder females’ careers.
Rationale:
Neck pain is a large health problem worldwide and often seen in musicians [1, 2]. Neck pain can radiate into the arm due to various underlying pain types and pain mechanisms making it heterogeneous in clinical signs and symptoms [3-5]. On the one hand, patients may present with dominant nociceptive neck-arm pain caused by activation of the nociceptors in muscles, joints, ligaments, fascia, tendons and the connective tissues of a nerve [6, 7]. Activation of nociceptors in nerve connective tissues may cause clinical signs of heightened nerve mechanosensitivity what is per definition categorized as nociceptive pain [6, 8, 9]. On the other hand, patients may present with dominant neuropathic pain, defined as pain as a direct consequence of a lesion or disease affecting the somatosensory system [10, 11]. The clinical profile of these different pain types is sometimes difficult to disentangle based on the localization and pain character [12]. Moreover, non-specific neck-arm pain patients shown a neuropathic pain component based on somatosensory changes detected via Quantitative Sensory Testing (QST) [3, 13]. Classifications with a defined physical examination pathway can be helpful to define subgroups to guide the clinical decision making [14]. This workshop updates the background about the pathophysiology of neck-arm pain and mediates an evidence-based examination to classify patients.
Purpose:
The aim of this workshop is to give a current insight into the background and evidence of neck-arm pain and to plan and practice a physical examination.
Content of Presentation:
This workshop will summarize evidence of neck-arm pain. Thereupon, current evidencebased diagnostic options will be presented and practiced together. Finally, a short insight in the management of neck-arm pain will be given.
Approach of Presentation:
QST testing and current cost-effective evidence-based methods will be presented to identify neuropathic components in neck-arm pain. Selected methods will be performed practically together, e.g. bedside sensory testing and neurodynamic tests.
Clinical Significance:
After the workshop, participants will have improved skills to diagnose in the spectrum of neck-arm pain for musicians with neck-arm pain.
At the end of the presentation, the participants will be able to:
- understand the heterogeneity of neck-arm pain,
- plan an appropriate diagnostic physical examination,
- have an insight in possible management strategies.
