Intercultural sensitization with synthetic cultures: Evaluation of a computer-based multimedia learning tool

The purpose of the present study was to evaluate a new computer-based multimedia learning tool for intercultural sensitization that is based on synthetic cultures. The learning tool named “Culture Awareness Training” (CAT) is targeted at learners with few intercultural experiences, and its aim is to sensitize participants to cultural influences on behavior and to intercultural differences, and to enhance perspective taking. Two studies were conducted to evaluate the effectiveness of the CAT. Study 1 (N = 107) showed that participation in the CAT led to higher intercultural awareness and higher intercultural interest compared to a control group. In Study 2 (N = 46), the CAT was compared to a simulation game for intercultural sensitization. Participants were students shortly before their stay abroad. Results showed that both the CAT and the classical simulation game enhanced participants’ cultural awareness.     

The relationship between strength asymmetries and jumping performance in professional volleyball players

Knee peak torque (PT) is associated to jump performance in volleyball players. It is not clear whether muscle strength imbalances of the knee joint can influence jump performance. The purpose of study was to analyse the association between PT and knee muscular imbalances with jump performance in professional volleyball players. Eleven elite male volleyball players (90.3 ± 9.7 kg body mass and 1.94 ± 0.06 m height) were evaluated in an isokinetic dynamometer at speeds of 60, 180 and 300 deg/s. Muscle strength imbalances were obtained through calculation of contralateral deficit between limbs and the conventional ratio (hamstrings/quadriceps). Countermovement jump (CMJ) was performed on a force plate to calculate mechanical power and height. Association was found between knee extensor PT at 180 deg/s with CMJ power (r = 0.610, p = 0.046). Conventional ratio at 300 deg/s showed negative association with CMJ (r = ?0.656, p = 0.029). The optimal ratio between knee extensors PT in relation to the flexors PT is associated with the greater mechanical power in CMJ. Contralateral deficit does not seem to be associated with the CMJ performance. Considering the knee extensor PT is associated with CMJ power, our findings suggest that strength-based training in volleyball athletes should not omit the conventional muscle ratio.     

National Security Letters,the USA PATRIOT Act,and the Constitution: The tensions between national security and civil rights

In response to the terrorist attacks of 9/11, the USA PATRIOT Act greatly expanded the ability of the Federal Bureau of Investigation to use National Security Letters (NSLs) in investigations and the contexts in which they could be used by relaxing the standards under which NSLs could be employed. NSLs allow investigators to acquire a significant amount of information about the subject of an investigation, and the range and frequency of uses of NSLs has risen dramatically since the passage of the USA PATRIOT Act. An outstanding question with NSLs is whether they are being used in a manner that violates the First and Fourth Amendments of the Constitution. This article explores the relationships between NSLs, the USA PATRIOT Act, and the Constitution. The paper reviews the legislative history of NSLs, synthesizes the First and Fourth Amendment issues and key judicial decisions related to NSLs, and analyzes the extent to which the USA PATRIOT Act Improvement and Reauthorization Act of 2005 adequately addresses challenges to the constitutionality of NSLs. The paper concludes with an examination of NSLs within the greater information policy context in the United States, as the expanded usage of NSLs—even if entirely constitutional—raises the possibility of chilling the freedom of expression.

Increased plasma zonulin in patients with sepsis

Introduction:

Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae’s zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. The loss of gut wall integrity during sepsis might be pivotal and has been described in various experimental as well as human studies. Increased levels of zonulin could be demonstrated in diseases associated with increased intestinal inflammation, such as celiac disease and type 1 diabetes. We therefore investigated the role of plasma levels of zonulin in patients with sepsis as a non-invasive marker of gut wall integrity.

Materials and methods:

Plasma level of zonulin was measured in 25 patients with sepsis, severe sepsis or septic shock according to ACCP/SCCM criteria at the first day of diagnosed sepsis. 18 non-septic post-surgical ICU-patients and 20 healthy volunteers served as control. Plasma levels were determined by using commercially available ELISA kit. Data are given as median and interquartile range (IQR).

Results:

Significantly higher plasma concentration of zonulin were found in the sepsis group: 6.61 ng/mL (IQR 3.51–9.46), as compared to the to the post-surgical control group: 3.40 ng/mL (IQR 2.14–5.70) (P = 0.025), as well as to the healthy group: 3.55 ng/mL (IQR 3.14–4.14) (P = 0.008).

Conclusion:

We were able demonstrate elevated levels of plasma zonulin, a potential marker of intestinal permeability in septic patients. Increased zonulin may serve as an additional mechanism for the observed increased intestinal permeability during sepsis and SIRS.
