Several approaches exist for estimating the derivatives of observed data for model exploration purposes, including functional data analysis (FDA; Ramsay &; Silverman, 2005 Ramsay, J. O., &; Silverman, B. W. (2005). Functional data analysis (2nd ed.). New York, NY: Springer-Verlag. [Google Scholar]), generalized local linear approximation (GLLA; Boker, Deboeck, Edler, &; Peel, 2010 Boker, S. M., Deboeck, P. R., Edler, C., &; Peel, P. K. (2010). Generalized local linear approximation of derivatives from time series. In S. Chow, E. Ferrer, &; F. Hsieh (Eds.), Statistical methods for modeling human dynamics: An interdisciplinary dialogue (pp. 161178). New York, NY: Taylor &; Francis. [Google Scholar]), and generalized orthogonal local derivative approximation (GOLD; Deboeck, 2010 Deboeck, P. R. (2010). Estimating dynamical systms: Derivative estimation hints from Sir Ronald A. Fisher. Multivariate Behavioral Research, 45, 725745. doi:10.1080/00273171.2010.498294[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). These derivative estimation procedures can be used in a two-stage process to fit mixed effects ordinary differential equation (ODE) models. While the performance and utility of these routines for estimating linear ODEs have been established, they have not yet been evaluated in the context of nonlinear ODEs with mixed effects. We compared properties of the GLLA and GOLD to an FDA-based two-stage approach denoted herein as functional ordinary differential equation with mixed effects (FODEmixed) in a Monte Carlo (MC) study using a nonlinear coupled oscillators model with mixed effects. Simulation results showed that overall, the FODEmixed outperformed both the GLLA and GOLD across all the embedding dimensions considered, but a novel use of a fourth-order GLLA approach combined with very high embedding dimensions yielded estimation results that almost paralleled those from the FODEmixed. We discuss the strengths and limitations of each approach and demonstrate how output from each stage of FODEmixed may be used to inform empirical modeling of young children’s self-regulation.  相似文献

In 2011, van Dijck and Fias described a positional SNARC (Spatial‐Numerical Association of Response Codes) effect: the SPoARC (Spatial‐Positional Association of Response Codes). To‐be‐remembered items (e.g., numbers, words) presented centrally on a screen seemed to acquire a left‐to‐right spatial dimension. If confirmed, this spatialization could be crucial for immediate memory theories. However, given the intricate links between visual and spatial dimensions, this effect could be due to the visual presentation (on a computer screen), which could have probed the left‐to‐right direction of reading/writing. To allow a generalization of this effect, we adapted van Dijck and Fias's (2011) task using an auditory version of Sternberg's paradigm. Lists of five consonants were auditorily presented at a rate of 3 s/item. A SPoARC effect was observed. The consequences are discussed first from an immediate memory perspective, putting forward the view that order could be coded through spatialization, and then in terms of similarities between SPoARC and SNARC.  相似文献

The main objective of this article is to address the impact of narrative practices in life celebration after the age of 80 and in the co-construction of a community-positive future. We share here an exploratory reflection about the narratives of a group of older women integrated in a community project. The Wednesday Tea Project (Chá das Quartas) has been ongoing for 4 years, and involves a group of old women experiencing high levels of loneliness and isolation in their small village in Portugal. The Wednesday Tea Project is based on positive psychology methodologies and consists of ritualized sessions that encourage participatory group dynamics. To describe how this project has highlighted the benefits of narrative practices, we utilized a series of scaffolding questions. Some of the most relevant outcomes of this project are: (a) the deconstruction of the dominant social discourse; (b) the publication of a book; (c) the reduction of loneliness feelings by re-membering significant figures; and (d) new levels of action both to women and the community as a consequence of a re-authoring process. Narrative practices seem to have contributed to the consolidation of all time dimensions, giving these women the opportunity to celebrate life after the age of 80, while also allowing the community to be part of and to benefit from the process. A reflection about the contributions of this article to a paradigm change toward positive aging is presented.  相似文献

Although it has been shown that identification with a neighbourhood community can support intergroup relations within the community by providing resources to cope with intergroup contact, previous research has not investigated how the perceived diversity of the neighbourhood identity influences this process. This study extends research on neighbourhood identification by focusing on a specific group (mothers of small children), examining how and when identification with other mothers living in the same neighbourhood is related to intergroup contact with local outgroup mothers. We examined this in a survey study, for which we collected data from both Finnish majority and immigrant mothers at public maternal and child healthcare centres (N = 733). Our study showed that identification with the neighbourhood mother community was positively associated with intergroup contact, partly via perceived social support from other neighbourhood mothers for both Finnish majority and immigrant mothers. Our study additionally revealed that the perceived proportion of outgroup mothers in the local mother community moderated the relationship between identification and intergroup contact for both groups. Our findings highlight the significance of considering perceived diversity for determining when identification will support intergroup contact.

Posttraumatic growth (PTG) and psychopathology are common outcomes following exposure to adversity and trauma. We examined the relationship of PTG to posttraumatic stress disorder (PTSD) and depression in a group of young Iraqi students with war trauma exposure. These young Iraqis had experienced an average of 13 different war‐related adversities. The prevalence of probable PTSD was 17.2% and probable depression 23.1%. PTSD was associated with higher and depression with lower PTG. In addition, the relationship between PTG and PTSD was stronger among males than females. Although PTSD and depression were relatively common, they were related to PTG in opposite directions.  相似文献

This article defends the content approach to aesthetic experience. It begins by sketching this approach to aesthetic experience. It then rehearses certain recent criticisms of the view by Alan Goldman and attempts to rebut them. One of those criticisms raises a long‐standing concern about the author's account that has recently been called the “qua” problem. The article concludes by putting this issue to rest.  相似文献

Honor means “high respect; esteem,” but it has different associations for different cultures. In honor cultures (Turkey), esteem depends on one's own perception of self‐worth and on other people's opinions. In those cultures, honor is easily lost and difficult to regain. In dignity cultures (northern America), esteem mainly depends on the individual and cannot be taken away by others. One way to lose honor in Turkey is through behaviors that may be seen as “potentially improper.” Thus, we expected that posting pictures of such behaviors on Facebook (e.g., at a party; with one's boyfriend/girlfriend) and letting others see them would be less likely in Turkey than in the northern United States. Moreover, we investigated whether honor endorsement was the reason for this difference. We examined participants' posting intentions and actual Facebook behaviors. As expected, Turkish participants were less willing to post and let others (especially their relatives) see their potentially improper pictures compared with northern Americans. Moreover, honor endorsement negatively predicted the willingness to post such pictures only in Turkey, especially for women. This suggests that in honor cultures, the concern for losing honor could be the underlying reason for avoiding social media postings that could be potentially perceived as improper.
