Does Diving Limit Brain Size in Cetaceans?

We test the longstanding hypothesis, known as the dive constraint hypothesis, that the oxygenation demands of diving pose a constraint on aquatic mammal brain size.Using a sample of 23 cetacean species we examine the relationship among six different measures of relative brain size, body size, and maximum diving duration. Unlike previous tests we include body size as a covariate and perform independent contrast analyses to control for phylogeny. We show that diving does not limit brain size in cetaceans and therefore provide no support for the dive constraint hypothesis. Instead, body size is the main predictor of maximum diving duration in cetaceans. Furthermore, our findings show that it is important to conduct robust tests of evolutionary hypotheses by employing a variety of measures of the dependent variable, in this case, relative brain size

In‐store shopping hassles: Conceptualization and classification

A positive shopping experience provides retailers with a competitive advantage. However, retail environments pose numerous hassles that may negatively affect consumer experiences. Integrating perspectives from attribution theory and expectation theory, we examine the concept of shopping hassle and how it differs from that of retail service failure. Furthermore, we utilize qualitative approaches to explore what shopping episodes consumers perceive as hassles. Conducting semi-structured in-depth interviews in Study 1, we develop a classification framework of in-store shopping hassles. In Study 2, we use a critical incident technique approach to gain a further understanding of types of shopping hassle

The Press Image of Community Health Nurses

The informational quality of press news about community health nurses is a critical factor in gaining the required public support for the scarce resources needed to advance community health nursing practice. Using content analyses, 2,561 articles on community health nursing for the period 1978–1981 were coded for key message themes and compared with articles on other nursing subjects. Results reveal that although the subject of community health nursing comprised the largest share of all clinical nursing articles, they are (1) less visible in newspapers, (2) distributed unevenly per capita among the various states, and (3) written so as to communicate low-quality information. Analysis of annual trends shows that community health nursing articles, while expanding in absolute numbers, constitute a declining proportion of nursing articles overall, and that the quality of information in current press coverage is diminishing. It is recommended that community health nurses embark on a concerted campaign to improve the quality of information carried in newspapers about their clinical specialty.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72770/1/j.1525-1446.1984.tb00425.x.pd
