Our first goal was to examine the relations among observational, physiological, and self‐report measures of children's anger. Our second goal was to investigate whether these relations varied by reactive or proactive aggression. Children (272 second‐grade boys and girls) participated in a procedure in which they lost a game and prize to a confederate who cheated. Skin conductance reactivity, heart rate reactivity, self‐reports of anger, angry facial expressions, and angry nonverbal behaviors were measured for each turn of the game. We used multi‐level regressions to calculate the relations among the 10 pairs of the five anger variables over the course of the game. Six of the 10 pairs of anger variables were positively related. These findings suggest that measuring children's anger using any one approach may not capture the full complexity of children's overall experience and expression of anger. Furthermore, three of the 10 relations were stronger at higher levels of reactive aggression, although none varied by proactive aggression. These findings suggest that reactive aggression is related to greater cohesiveness in the experience and expression of anger than is proactive aggression. 相似文献
Assume that we have ni independent observations from each of k independent populations. Each population has the same distribution except for a translation parameter. We are interested in specific pairwise differences of the parameters in various settings, such as treatment vs. control, change point or all pairwise differences. We propose new multiple testing procedures for the pairwise differences. The new procedures are based on ranks and they have desirable practical properties not shared by existing procedures. These include tests that satisfy the interval property. Furthermore, the test method provides an interval that serves as an estimate of the difference in the parameters of interest. 相似文献
ABSTRACT In the stepwise procedure of selection of a fixed or a random explanatory variable in a mixed quantitative linear model with errors following a Gaussian stationary autocorrelated process, we have studied the efficiency of five estimators relative to Generalized Least Squares (GLS): Ordinary Least Squares (OLS), Maximum Likelihood (ML), Restricted Maximum Likelihood (REML), First Differences (FD), and First-Difference Ratios (FDR). We have also studied the validity and power of seven derived testing procedures, to assess the significance of the slope of the candidate explanatory variable x2 to enter the model in which there is already one regressor x1. In addition to five testing procedures of the literature, we considered the FDR t-test with n ? 3 df and the modified t-test with n? ? 3 df for partial correlations, where n? is Dutilleul's effective sample size. Efficiency, validity, and power were analyzed by Monte Carlo simulations, as functions of the nature, fixed vs. random (purely random or autocorrelated), of x1 and x2, the sample size and the autocorrelation of random terms in the regression model. We report extensive results for the autocorrelation structure of first-order autoregressive [AR(1)] type, and discuss results we obtained for other autocorrelation structures, such as spherical semivariogram, first-order moving average [MA(1)] and ARMA(1,1), but we could not present because of space constraints. Overall, we found that:
the efficiency of slope estimators and the validity of testing procedures depend primarily on the nature of x2, but not on that of x1;
FDR is the most inefficient slope estimator, regardless of the nature of x1 and x2;
REML is the most efficient of the slope estimators compared relative to GLS, provided the specified autocorrelation structure is correct and the sample size is large enough to ensure the convergence of its optimization algorithm;
the FDR t-test, the modified t-test and the REML t-test are the most valid of the testing procedures compared, despite the inefficiency of the FDR and OLS slope estimators for the former two;
the FDR t-test, however, suffers from a lack of power that varies with the nature of x1 and x2; and
the modified t-test for partial correlations, which does not require the specification of an autocorrelation structure, can be recommended when x1 is fixed or random and x2 is random, whether purely random or autocorrelated. Our results are illustrated by the environmental data that motivated our work.
Abstract Six scholars in applied psychology wrote thoughtful and provocative reactions to a paper written by the author that presented a case for broadening the content and language of organizational behavior management (OBM) in order to enhance appreciation for OBM in organizational settings and among university faculty and students in mainstream psychology programs. This paper summarizes the follow-up commentaries and adds justification for key points made in the target article. Five topics are addressed: (1) critical distinctions between OBM and industrial/organizational psychology, (2) disadvantages of using negative over positive reinforcement to motivate behavior change, (3) the need to after OBM language in order to increase interest and application, (4) the use of unobservable person state vs. personality traits to explain behavior, and (5) the challenge of improving the education and training of students in OBM programs. 相似文献
Drawing on interviews with 40 Polish migrants in the UK, ethnographic and autobiographical research, the article applies the concept of anchoring to theorise the flexibility of migrants’ adaptation and ‘settlement’. Simultaneity, multidimensionality and changeability of anchoring and the reverse processes of un-anchoring are examined here to bridge the divide between the ‘sedentarist’ and the mobility perspectives. The paper particularly focuses on anchors overlooked in the adaptation and integration literature, such as: performing gender; daily practices; spirituality; leisure activities; attachment to nature; material objects and technology; as well as constraining illnesses and addictions. 相似文献
Recent changes in the world of work have modified the conditions of the exercise of management in ways that challenge managers’ traditional authority and identity, both symbolically and physically. In this context, we analyse the “visibilizing process” of managers, through which they attempt to make themselves more visible, in ways that reaffirm their authority and restore their identity as managers. To that end, we develop a Foucauldian framework on power and visibility, which sheds light on the “political economy of visibility” of the manager. We apply this framework to a case study that encouraged a re-spatialization of remote work in coworking spaces. The findings show how the manager in our case study staged his own visibility, by enhancing managerial control, to manage his invisibility and shape his intertwined identities. Through the visibilizing process, the manager legitimated his role, materialized his function, and restored his authority. 相似文献
