Die vorliegende Arbeit fokussiert auf den fairen Konsum als Teil des ethischen Konsums. Unter fairem Konsum verstehen wir Kaufentscheidungen, die unter Berücksichtigung der Einhaltung fairer Arbeits- und Geschäftsbedingungen bei der Herstellung von Produkten erfolgen. Unter Einsatz einer neu entwickelten Skala zur Messung des fairen Konsumbewusstseins können wir empirisch nachweisen, dass Produkte mit einem Fairtrade-Siegel Konsumenten einen moralischen Zusatznutzen vermitteln können, für den sie bereit sind, einen Mehrpreis zu zahlen.
Praxismodelle im Studium : Chancen und Probleme aus der Perspektive von Potsdamer Studierenden
(2012)
Background: Several equipment interventions like optimizing seat position or optimizing shoe/insole/pedal interface are suggested to reduce overuse injury in cycling. Data analyzing clinical or biomechanical effects of those interventions is sparse. Foot orthoses out of carbon fiber are one possibility to alter the interface between foot and pedal. The aim of this study was therefore to analyze plantar pressure distribution in carbon fiber foot orthoses in comparison to standard insoles of commercially available cycling shoes. Materials and Methods: 11 pain-free triathletes (Age: 29 +/- 9, 1.77 +/- 0.04 m, 68 5 kg) were tested on a cycle ergometer at 60 and 90 rotations per minute (rpm) at workloads of 200 and 300 Watts. Subjects wore in randomized order a cycling shoe with its standard insole (control condition CO) or the shoe with carbon fiber foot orthoses (Condition CA). Mean peak pressure out of 30 movement cycles were extracted for the total foot and specific foot regions (rear, mid, fore foot (medial, central, lateral) and toe region). Three-factor ANOVAs (factor foot orthoses, rpm, workload) for repeated measures (alpha = 0.05) were used to analyze the main question of a foot orthoses effect on peak in-shoe plantar pressure. Results: Peak pressures in the total foot were in a range of 70-75 kPa for 200 Watts (W) (300 W: 85-110 kPa). The carbon fiber foot orthoses reduced peak pressures by -4,1% compared to the standard insole (p = 0,10). In the foot regions rear(-16,6%, p<0.001), mid (-20,0%, p<0.001) and fore foot (-5.9%, p < 0.03)CA reduced peak pressure compared to CO. In the toe region, peak pressure was higher in CA (+16,2%) compared to CO (p<0,001). The lateral fore foot showed higher peak pressures in CA (+34%) and CO (+59%) compared to medial and central fore foot. Conclusion: Carbon fiber can serve as a suitable material for foot orthoses manufacturing in cycling. Plantar pressures do not increase due to the stiffness of the carbon. Individual customization may have the potential to reduce peak pressure in certain foot areas.

Einleitung
(2012)
Als Antwort auf die Herausforderungen der Sinn- und Wertekrise der Moderne besinnt sich Paul Valéry auf das geistige Vermögen des Menschen und entwirft eine radikal subjektive und lebensnahe Philosophie. Der Philosoph wird bei ihm zum Dichter, der mittels Metaphern sein Denken in Bilder fasst. Philosophie ist für ihn Denkkunst, die die Möglichkeiten des Lebens abbildet, zum Denken anregt und den ...
Wege zum Reichtum
(2012)
Auf welchen Wegen werden private Haushalte in Deutschland reich und unter welchen individuellen und strukturellen Umständen vollziehen sich diese Prozesse? Melanie Böwing-Schmalenbrock untersucht gesellschaftliche Verteilungsprozesse und weist auf eine entscheidende Bedingung moderner Gesellschaften hin: die individuelle Chance auf gesellschaftliche Teilhabe und freie Lebensführung. Die Entstehung von Reichtum erweist sich als ein komplexes Zusammenspiel verschiedener Reichtumsquellen, es wird die erhebliche Relevanz von Arbeit und Erbschaft deutlich sowie die entscheidende Rolle der Persönlichkeit.
Dietary records are often biased, especially those of overweight individuals. The purpose of the study was to investigate underreporting among persons of normal weight with a very high energy intake (El).
The total energy expenditure (TEE) of 16 elite athletes (BMI 24 +/- 2 kg/m(2)) and 17 controls (BMI 23 3 kg/m2) was measured using the doubly-labeled water technique (DLW, 14d). El was estimated using 2 x 3-day dietary records. Underreporters were identified by BLACK'S cut-off (El:TEE < 0.76). 44% of athletes (El: 3584 824 kcal/d; TEE: 4621 1460 kcal/d) and 29% of controls (El: 2552 680 kcal/d; TEE: 3151 822 kcal/d) were identified as underreporters. TEE explains 52% of underreporting. In summary, a high energy intake seems to strongly predict underreporting. Prevalence and magnitude of underreporting increase with increasing energy intake.
Intra- and interrater variability of sonographic investigations of patella and achilles tendons
(2012)
Background: Clinical examinations of tendon disorders routinely include ultrasound examinations, despite the fact that availability of data concerning validity criteria of these measurements are limited. The present study therefore aims to evaluate the reliability of measurements of Achilles- and Patella tendon diameter and in the detection of structural adaptations.
Materials and Methods: In 14 healthy, recreationally active subjects both asymptomatic Achilles (AT) and patella tendons (PT) were measured twice by two examiners in a test-retest design. Besides the detection of anteroposterior (a.p.-) and mediolateral (m.l.-) diameters, areas of hypoechogenicity and neovascularisation were registered. Data were analysed descriptively with calculation of test-retest variability (TRV), intraclass-correlation coefficient (ICC) and Bland and Altman's plots with bias and 95% limits of agreement (LOA).
Results: Intra- and interrater differences of AT- and PT-a.p.-diameter varied from 0.2 - 1.2 mm, those of AT- and PT-m.l-diameter from 0.7-5.1 mm. Areas of hypoechogenicity were visible in 24% of the tendons, while 15% showed neovascularisations. Intrarater AT-a.p.-diameters showed sparse deviations (TRV 4.5-7.4%; ICC 0.60-0.84; bias -0.05-0.07 mm; LOA-0.6-0.5 to -1.1 - 1.0 mm), while interrater AT- and PT-m.l.-diameters were highly variable (TRV 13.7-19.7%; ICC 0.11-0.20; bias -1.4-4.3 mm; LOA-5.5-2.7 to -10.5 - 1.9 mm).
Conclusion: Our results suggest that the measurement of AT- and PT-a.p.-diameters is a reliable parameter. In contrast, reproducibility of AT- and PT-m.l.-diameters is questionable. The study corroborates the presence of hypoechogenicity and neovascularisation in asymptomatic tendons.
