Autonomic stress responses elicited by watching a live broadcast soccer game: a pilot study

Aim: Increased rates of hospitalization due to cardiovascular events have been reported during phases of World Soccer Championships (WSC). The purpose of this pilot study was to explore acute psychological and physiological effects of watching a live broadcast soccer game during the WSC 2006. Methods: Seven male supporters (age: M=24; SD=2.7) of the Swiss National Soccer Team watched a game of their team in a controlled laboratory setting. Heart rate (HR), heart rate variability (HRV), salivary cortisol, alpha-amylase (sAA), and testosterone concentrations, as well as several mood ratings were captured repeatedly before, during, and after the game. Results: Subjects reported feeling stressed, and HR and sAA activity showed an increase during the game. In contrast, HRV, cortisol and testosterone were unaffected. Conclusion: Watching a sports competition seems to specifically affect the sympathetic nervous system, which can be measured by sensitive electrocardiographic and salivary markers.

Watching Eyes - Effekte an Recyclingsammelstellen

Weniger unsachgemässe Abfallentsorgung dank Watching Eyes – dies war die These unseres Feldexperiments. In fünf Gemeinden der Region Bern und Olten wurde während drei Monaten die Wirkung von aufklebbaren Augenpaaren (sog. „Watching Eyes“) auf die unsachgemässe Abfallentsorgung bei Recyclingsammelstellen getestet. Die Menge des Abfalls konnte durch Watching Eyes um bis zu 35 % reduziert werden. Ebenfalls bestätigt wurden die zusätzlichen Erwartungen, dass an Unterflur - Containertypen und an offen einsehbaren Sammelstellen weniger Müll unsachgemäss abgestellt wird. Alle Erkenntnisse passen in die Theorie, dass Benutzer der Sammelstellen sich eher normkonform verhalten, wenn sie sich beobachtet fühlen. Ausserdem macht diese Forschungsarbeit Hoffnung, dass Watching Eyes für ein gesellschaftsrelevantes Problem, die unsachgerechte Abfallentsorgung, Hilfestellung bieten können. Watching Eyes - Aufkleber entfalten ihren grössten Effekt auf soziales Verhalten bei dauerhafter Anwendung. Dieser Effekt vermag die illegal deponierten Müllmengen an Recyclingsammelstellen um rund ein Drittel zu reduzieren. Weiter kann Gemeinden empfohlen werden, in Unterfluranlagen zu investieren und von den alten, traditionellen Containern abzusehen, da dadurch die Menge deponierten Abfalls deutlich reduziert werden kann.

Identification of problems in functioning of people with sleep disorders in a clinical setting using the International Classification of Functioning Disability and Health (ICF) Checklist

We conducted an explorative, cross-sectional, multi-centre study in order to identify the most common problems of people with any kind of (primary) sleep disorder in a clinical setting using the International Classification of Functioning, Disability and Health (ICF) as a frame of reference. Data were collected from patients using a structured face-to-face interview of 45-60 min duration. A case record form for health professionals containing the extended ICF Checklist, sociodemographic variables and disease-specific variables was used. The study centres collected data of 99 individuals with sleep disorders. The identified categories include 48 (32%) for body functions, 13 (9%) body structures, 55 (37%) activities and participation and 32 (22%) for environmental factors. 'Sleep functions' (100%) and 'energy and drive functions', respectively, (85%) were the most severely impaired second-level categories of body functions followed by 'attention functions' (78%) and 'temperament and personality functions' (77%). With regard to the component activities and participation, patients felt most restricted in the categories of 'watching' (e.g. TV) (82%), 'recreation and leisure' (75%) and 'carrying out daily routine' (74%). Within the component environmental factors the categories 'support of immediate family', 'health services, systems and policies' and 'products or substances for personal consumption [medication]' were the most important facilitators; 'time-related changes', 'light' and 'climate' were the most important barriers. The study identified a large variety of functional problems reflecting the complexity of sleep disorders. The ICF has the potential to provide a comprehensive framework for the description of functional health in individuals with sleep disorders in a clinical setting.

Simple virtual reality display of fetal volume ultrasound

Three-dimensional (3D) ultrasound volume acquisition, analysis and display of fetal structures have enhanced their visualization and greatly improved the general understanding of their anatomy and pathology. The dynamic display of volume data generally depends on proprietary software, usually supplied with the ultrasound system, and on the operator's ability to maneuver the dataset digitally. We have used relatively simple tools and an established storage, display and manipulation format to generate non-linear virtual reality object movies of prenatal images (including moving sequences and 3D-rendered views) that can be navigated easily and interactively on any current computer. This approach permits a viewing or learning experience that is superior to watching a linear movie passively.
