The Mechanics of Duetting in a New Zealand Endemic, the Kokako (Callaeas cinerea wilsoni): Song at a Snail's Pace

ETHOLOGY, Issue 5 2006
Laura E. Molles
New Zealand's endemic, duetting kokako (Callaeas cinerea wilsoni) produce one of the longest known bird songs (ca 30 s) and duets that differ strikingly from those of most duetters in their unusual length and non-repetitive structure, long pauses between component phrases, and the great flexibility in sex roles. Here we present a structural analysis of the vocalizations of 17 kokako pairs collected during natural song bouts and in response to conspecific playback, to gain insight into the functional role of this extraordinary vocal behavior. Males tend to sing a greater proportion of the duet than females. Like many duetting species, kokako have a moderately sized repertoire of phrases (mean repertoire size =18) and pair members tend to sing antiphonally rather than in unison. Sharing of phrase types is high among neighboring kokako ( = 86%) and repertoires are not sex specific, as is typical of some but not all duetting species. Timing characteristics, broad sharing of phrase types, and countersinging behavior strongly suggest that kokako duets play an important role in territory defense. Additionally, differences in pairs' sex role and phrase sequence flexibility suggest that these aspects of duet performance may reflect pair-bond length or commitment, and require a time investment by pair members.

Employee satisfaction with meetings: A contemporary facet of job satisfaction

HUMAN RESOURCE MANAGEMENT, Issue 2 2010
Steven G. Rogelberg
Abstract Given the ubiquity, time investment, and theoretical relevance of meetings to work attitudes, this study explored whether organizational science should consider employee satisfaction with meetings as a contemporary, important, and discrete facet of job satisfaction. Using affective events theory, we postulated that meetings are affect-generating events that meaningfully contribute to overall job satisfaction. Two surveys queried working adults: Study 1 used a paper-based survey (n = 201), while Study 2 used an Internet-based survey (n = 785). Satisfaction with meetings was positively related to and significantly predicted overall job satisfaction (p < .05) after controlling for individual difference variables (e.g., participant background variables, negative affect), traditional job satisfaction facets (e.g., work, supervision, pay), and other conceptually relevant constructs (e.g., satisfaction with communication, organizational commitment). Exploratory (Study 1) and confirmatory (Study 2) factor analyses provided evidence that meeting satisfaction is a distinct facet of job satisfaction. Finally, as hypothesized, the relationship between meeting satisfaction and job satisfaction depends in part upon the number of meetings typically attended. The relationship was stronger (more positive) when meeting demands were higher and weaker when meeting demands were lower. Implications for assessment, leadership development, on-boarding, and high potential initiatives are discussed. ©2010 Wiley Periodicals, Inc. [source]

Trait-Specific Dependence in Romantic Relationships

JOURNAL OF PERSONALITY, Issue 5 2002
Bruce J. Ellis
ABSTRACT Informed by three theoretical frameworks,trait psychology, evolutionary psychology, and interdependence theory,we report four investigations designed to develop and test the reliability and validity of a new construct and accompanying multiscale inventory, the Trait-Specific Dependence Inventory (TSDI). The TSDI assesses comparisons between present and alternative romantic partners on major dimensions of mate value. In Study 1, principal components analyses revealed that the provisional pool of theory-generated TSDI items were represented by six factors: Agreeable/Committed, Resource Accruing Potential, Physical Prowess, Emotional Stability, Surgency, and Physical Attractiveness. In Study 2, confirmatory factor analysis replicated these results on a different sample and tested how well different structural models fit the data. Study 3 provided evidence for the convergent and discriminant validity of the six TSDI scales by correlating each one with a matched personality trait scale that did not explicitly incorporate comparisons between partners. Study 4 provided further validation evidence, revealing that the six TSDI scales successfully predicted three relationship outcome measures,love, time investment, and anger/upset,above and beyond matched sets of traditional personality trait measures. These results suggest that the TSDI is a reliable, valid, and unique construct that represents a new trait-specific method of assessing dependence in romantic relationships. The construct of trait-specific dependence is introduced and linked with other theories of mate value. [source]

Are Parents Investing Less Time in Children?

POPULATION AND DEVELOPMENT REVIEW, Issue 4 2004
Trends in Selected Industrialized Countries
Trends in parental time invested in children since the 1960s are examined in 16 industrialized countries using time-use survey data. Despite the time pressures that confront today's families, parents appear to be devoting more time to children than they did 40 years ago. Results also suggest that mothers continue to devote more time to childcare than fathers, but the gender gap has been reduced. The consistency of these results across countries suggests a global trend toward an increase in parental time investment in children. Multivariate analysis of trends in parental time by type of activity was undertaken for Canada. It revealed a significant increase in parental time even after controlling for changes in the demographic composition of the population during the past few decades. [source]

THE ROLE OF NONCOGNITIVE SKILLS IN EXPLAINING COGNITIVE TEST SCORES

ECONOMIC INQUIRY, Issue 1 2008
LEX BORGHANS
This article examines whether noncognitive skills,measured both by personality traits and by economic preference parameters,influence cognitive tests' performance. The basic idea is that noncognitive skills might affect the effort people put into a test to obtain good results. We experimentally varied the rewards for questions in a cognitive test to measure to what extent people are sensitive to financial incentives. To distinguish increased mental effort from extra time investments, we also varied the questions' time constraints. Subjects with favorable personality traits such as high performance motivation and an internal locus of control perform relatively well in the absence of rewards, consistent with a model in which trying as hard as you can is the best strategy. In contrast, favorable economic preference parameters (low discount rate, low risk aversion) are associated with increases in time investments when incentives are introduced, consistent with a rational economic model in which people only invest when there are monetary returns. The main conclusion is that individual behavior at cognitive tests depends on noncognitive skills. (JEL J20, J24) [source]
