Effects of Task Instructions and Brief Breaks on Brainstorming

Abstract: Experiment 1 examined the effects of additional brainstorming rules for groups and looked at whether the presence of a facilitator who actively enforced the rules of brainstorming was beneficial. Experiments 2 and 3 examined whether the additional rules and brief breaks were beneficial to individual brainwriters and electronic brainstormers working alone. Clear benefits of the additional rules were found under a variety of conditions. The presence of a facilitator to enforce the rules enhanced the efficiency of idea generation (number of words used to express ideas) but not the number of ideas generated. There appears to be a small benefit to taking breaks in brainwriting sessions, but the benefit of breaks is reduced or eliminated in electronic brainstorming sessions.

Errors in Potassium Measurement: A Laboratory Perspective for the Clinician

Abstract: Errors in potassium measurement can cause pseudohyperkalemia, where serum potassium is falsely elevated. Usually, these are recognized either by the laboratory or the clinician. However, the same factors that cause pseudohyperkalemia can mask hypokalemia by pushing measured values into the reference interval. These cases require a high-index of suspicion by the clinician as they cannot be easily identified in the laboratory. This article discusses the causes and mechanisms of spuriously elevated potassium, and current recommendations to minimize those factors. "Reverse" pseudohyperkalemia and the role of correction factors are also discussed. Relevant articles were identified by a literature search performed on PubMed using the terms "pseudohyperkalemia," "reverse pseudohyperkalemia," "factitious hyperkalemia," "spurious hyperkalemia," and "masked hypokalemia."

The influence of culture on advertising effectiveness in China and the USA

Abstract: Presents findings from an empirical study which investigates the effects of different advertising appeals used across cultures. Cultural differences along the individualism‐collectivism dimension are hypothesized to affect people’s reactions to certain advertising appeals. Results indicate that appeals which emphasize individualistic benefits are more effective in the USA than in China. When appeals emphasizing collectivistic benefits are employed, they are generally more effective in China. However, such effects can be moderated by product characteristics. Different product types may serve to influence the effectiveness of culturally‐congruent advertising appeals. Discusses the implications of the findings.

Performance analysis of optical CDMA with prime codes

Abstract: An ‘extended’ prime code is introduced for optical code-division multiple access (CDMA). The probability distribution of the interference generated by crosscorrelation functions of the original and extended prime codes are derived analytically. The performances of both codes are then analysed using a Gaussian approximation. Finally, the extended prime code is shown to be preferable to the original code.
