The role of daily need crafting in daily fluctuations in adolescents’ need-based and affective experiences

Based on self-determination theory, this diary study examined associations between adolescents’ daily need crafting and daily fluctuations in their need-based and affective experiences. We also examined the role of daily perceived autonomy-supportive parenting in adolescents’ daily need-crafting. Adolescents (N?=?159; M_age?=?15.56; 62% female) filled out a diary for seven consecutive days. Multilevel path analyses indicated that need crafting varied on a day-to-day basis, with daily need crafting relating positively to daily positive affect and negatively to negative affect. The benefits of daily need crafting were accounted for by higher daily need satisfaction and lower need frustration. Further, on days adolescents perceived more parental autonomy support, they reported more need satisfaction and less need frustration, an effect that was partially due to higher need crafting that day. Overall, the results suggest that need crafting represents a critical pro-active skill, with resulting benefits for adolescents’ daily need-based experiences and well-being.

The chameleon effect,the temporal aspects of mimicry and their impact on service measurement

BackgroundIn an experiment conducted in a natural setting, we test the link between mimicry, the amount of time during which the mimicry behavior takes place, and its impact on service quality.MethodsCable TV clients (n = 120) were randomly assigned to six experimental conditions (2 mimicry conditions: verbal mimicry vs. no mimicry x 3 interaction time: 5 vs. 10 vs. 15 minutes). Perceived service quality served as the dependent measurement.ResultsA main effect of mimicry was found on service quality: a cable TV representative was perceived more favorably when he mimicked the customer. Importantly, it was shown that even small portions of mimicry are beneficial, meaning that practitioners do not have to mimic someone for a long time to achieve benefits.ConclusionThe paper shows new benefits for the mimicker: more positive judgments by the mimickee regarding the impact on several different levels of service quality.     

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

     

Statistical Significance of the Contribution of Variables to the PCA solution: An Alternative Permutation Strategy

In this paper, the statistical significance of the contribution of variables to the principal components in principal components analysis (PCA) is assessed nonparametrically by the use of permutation tests. We compare a new strategy to a strategy used in previous research consisting of permuting the columns (variables) of a data matrix independently and concurrently, thus destroying the entire correlational structure of the data. This strategy is considered appropriate for assessing the significance of the PCA solution as a whole, but is not suitable for assessing the significance of the contribution of single variables. Alternatively, we propose a strategy involving permutation of one variable at a time, while keeping the other variables fixed. We compare the two approaches in a simulation study, considering proportions of Type I and Type II error. We use two corrections for multiple testing: the Bonferroni correction and controlling the False Discovery Rate (FDR). To assess the significance of the variance accounted for by the variables, permuting one variable at a time, combined with FDR correction, yields the most favorable results. This optimal strategy is applied to an empirical data set, and results are compared with bootstrap confidence intervals.     

Using trained pouched rats to detect land mines: another victory for operant conditioning

We used giant African pouched rats (Cricetomys gambianus) as land mine-detection animals in Mozambique because they have an excellent sense of smell, weigh too little to activate mines, and are native to sub-Saharan Africa, and therefore are resistant to local parasites and diseases. In 2009 the rats searched 93,400 m(2) of land, finding 41 mines and 54 other explosive devices. Humans with metal detectors found no additional mines. On average, the rats emitted 0.33 false alarm for every 100 m(2) searched, which is below the threshold given by International Mine Action Standards for accrediting mine-detection animals. These findings indicate that Cricetomys are accurate mine-detection animals and merit continued use in this capacity.     

Beyond shared perceptions of trust and monitoring in teams: implications of asymmetry and dissensus

Past research has implicitly assumed that only mean levels of trust and monitoring in teams are critical for explaining their interrelations and their relationships with team performance. In this article, the authors argue that it is equally important to consider the dispersion in trust and monitoring that exists within teams. The authors introduce "trust asymmetry" and "monitoring dissensus" as critical dispersion properties of trust and monitoring and hypothesize that these moderate the relationships between mean monitoring, mean trust, and team performance. Data from a cross-lagged panel study and a partially lagged study support the hypotheses. The first study also offered support for an integrative model that includes mean and dispersion levels of both trust and monitoring. Overall, the studies provide a comprehensive and clear picture of how trust and monitoring emerge and function at the team level via mean and dispersion.
