Systematic Review of countermeasures to minimise physiological changes and risk of injury to the lumbopelvic area following long-term microgravity
No full textBackgroundNo studies have been published on an astronaut population to assess the effectiveness of countermeasures for limiting physiological changes in the lumbopelvic region caused by microgravity exposure during spaceflight. However, several studies in this area have been done using spaceflight simulation via bed-rest. The purpose of this systematic review was to evaluate the effectiveness of countermeasures designed to limit physiological changes to the lumbopelvic region caused by spaceflight simulation by means of bed-rest.MethodsElectronic databases were searched from the start of their records to November 2014. Studies were assessed with PEDro, Cochrane Risk of Bias and a bed-rest study quality tool. Magnitude based inferences were used to assess countermeasure effectiveness.ResultsSeven studies were included. There was a lack of consistency across studies in reporting of outcome measures. Some countermeasures were found to be successful in preventing some lumbopelvic musculoskeletal changes, but not others. For example, resistive vibration exercise prevented muscle changes, but showed the potential to worsen loss of lumbar lordosis and intervertebral disc height.ConclusionFuture studies investigating countermeasures should report consistent outcomes, and also use an actual microgravity environment. Additional research with patient reported quality of life and functional outcome measures is advocated

Creative Disobedience: Dorothee Sölle\u27s Political Theology and Ethics for U.S. Christian Contexts
No full textThis dissertation adapts Dorothee Sölle’s concept of creative disobedience to account for those histories of obedience to structures of domination and to foster moral agency that disrupts and dismantles structures of domination. The first two chapters contextualize and summarize Dorothee Sölle’s critique of obedience and her warning against the way in which the obedient social character yields a “Christofascist” society. Chapter II considers the extent to which Christofascism already exists in US society today through Andrew L. Whitehead and Samuel L. Perry’s study of the political and cultural prevalence of Christian nationalism. Chapter III contextualizes Dorothee Sölle’s theoretical critique of obedience through Erich Fromm’s concept of social character, Pierre Bourdieu’s concept of habitus and Elisabeth Schüssler Fiorenza’s concept of kyriocentrism. In Chapter III, the author shows how histories and structures forming US white-Christian social character--white supremacy, coloniality and kyriarchy--require white-Christian obedience to the same Christian nationalist structures of power, boundaries and order. Chapter IV summarizes Sölle’s feminist theology which argues that creative disobedience is necessary for Christian moral agency. Finally, Chapter V adapts Sölle’s creative disobedience as an ethical process for progressive white-Christians in the US today. This chapter explains how moral agency defined by creative disobedience would foster habits and practices that lead to effective participation in political transformation, rather than reinforcing relationships and structures of domination
Deixis: Textdeixis
No full textGerman language is characterized by a frequent use of deictic expressions. Those expressions are used in different types of communicative settings. They also include the text, which may be conceptualized on the one hand as a space and on the other hand as a chronological arrangement of actions. Textdeictic devices belong to the strategies of reader orientation. They are usually embedded in comments of the author on textual organization and include different types of deictic (or paradeictic) expressions, such as demonstrative pronouns and adverbs.Die deutsche Sprache zeichnet sich durch einen reichen Strukturausbau in Hinblick auf den Bestand an deiktischen und deiktisch abgeleiteten Ausdrucksmitteln aus (Ehlich z.B. 2007c, Redder 2010a). Ausdrücke wie dieser, hier und jetzt gehören zum Kernbestand dieses deiktischen Inventars. Sie können auf unterschiedliche Verweisräume Bezug nehmen: Wahrnehmungsraum, Vorstellungsraum, Wissensraum, Diskursraum, Rederaum, Textraum (Redder 2000, Ehlich 1976). Auf den Textraum können sich ebenfalls Ausdrücke beziehen, die nicht im engeren Sinne als Verweisausdrücke gelten, im Textzusammenhang aber deiktisch funktionalisiert werden können (wie etwa zuvor oder eingangs). Auch Partizipien (wie anschließend) oder Nominalgruppen (wie zum Abschluss, im Folgenden) werden textdeiktisch verwendet ebenso wie zusammengesetzte, deiktisch abgeleitete Ausdrücke (wie danach, hiermit, sodann), die auch in Kombination mit Präpositionalphrasen vorkommen (im Anschluss daran) und zum Teil eine konnektive Funktion ausüben (Redder 2010b). Der Beitrag enthält neben einer Bestandsaufnahme der Behandlung textdeiktischer Phänomene in Übungsgrammatiken Anaysen zu ausgewählten Beispielen - auch in Hinblick auf den Einsatz in der Didaktik

Countermeasure Development for Lumbopelvic Deconditioning in Space
No full textPhysical inactivity and lumbopelvic deconditioning have been linked to increased incidence of non-specific low back pain (LBP) and spinal injury in those exposed to microgravity (e.g. Astronauts and long duration bed rest) and in the general population. Astronauts have an increased risk of experiencing moderate to severe LBP during microgravity exposure and herniated intervertebral discs within one year following spaceflight. Atrophy and reduced motor control of the lumbar multifidus (LM) and transversus abdominis (TrA) muscles resulting from periods of deconditioning is linked to non-specific LBP and spinal injury risk in both post flight astronauts and general populations. However, voluntary recruitment of these two key muscles is difficult and presents a rehabilitation challenge. This chapter reviews the concept of spinal stability as it relates to microgravity, discusses how existing exercise countermeasures used in space do not successfully maintain lumbopelvic muscle size, and introduces the Functional Readaptive Exercise Device (FRED) that shows potential to activate the LM and TrA muscles automatically and in a tonic fashion, which has relevance to rehabilitation of both astronaut and terrestrial populations
