Differential susceptibility to adolescent externalizing trajectories: examining the interplay between CHRM2 and peer group antisocial behavior     

Latendresse SJ  Bates JE  Goodnight JA  Lansford JE  Budde JP  Goate A  Dodge KA  Pettit GS  Dick DM 《Child development》2011,82(6):1797-1814

The present study characterized prototypical patterns of development in self-reported externalizing behavior, between 12 and 22 years of age, within a community sample of 452 genotyped individuals. A Caucasian subset (n = 378) was then examined to determine whether their probabilities of displaying discrete trajectories were differentially associated with CHRM2, a gene implicated in self-regulatory processes across a range of externalizing behaviors, and if affiliating with antisocial peers moderated these associations. Findings indicate that relative to a normative "lower risk" externalizing trajectory, likelihood of membership in two "higher risk" trajectories increased with each additional copy of the minor allelic variant at CHRM2, and that this association was exacerbated among those exposed to higher levels of peer group antisocial behavior.  相似文献   

Designing governance for shared services organizations in the public service     

Gerald GrantAuthor Vitae  Shawn McKnightAareni UruthirapathyAuthor Vitae  Allen BrownAuthor Vitae 《Government Information Quarterly》2007

As shared services organizations (SSO) become more popular as a service management and delivery option in government, properly defining and setting up the governance structure continues to be a key success factor. This paper explores the options and issues to consider when selecting and implementing shared services governance including topics such as oversight, accountability, culture, management of resources, and of day-to-day operations. Shared services organizations are increasingly common in private sector companies and the particular challenges involved in the governance of an SSO in a public service context are highlighted and discussed.  相似文献   

When to intervene in selective mutism: The multimodal treatment of a case of persistent selective mutism     

Shawn Powell  Mahlon Dalley 《Psychology in the schools》1995,32(2):114-123

An identification and treatment model differentiating Transient from Persistent Selective Mutism is proposed. The model incorporates treatment recommendations for Persistent Selective Mutism and suggests that interventions are not usually warranted for Transient Selective Mutism. The case study of a 6-year-old female manifesting Persistent Selective Mutism is presented. A multimodal treatment approach combining behavioral techniques with play therapy and family involvement was applied to improve her verbal interactions. Pre- and posttreatment evaluations were conducted. During pretreatment evaluations the child was manifesting Persistent Selective Mutism, immaturity, and withdrawal behaviors. At posttreatment evaluations she was talking in a manner consistent with her peers without problematic behaviors displayed. Results of a 6-month follow-up completed after the child had entered first grade showed that she was continuing to speak in a manner consistent with her peers without behavioral concerns.  相似文献

Relationships between exercise regulations and motivational consequences in university students     

Wilson PM  Rodgers WM  Fraser SN  Murray TC 《Research quarterly for exercise and sport》2004,75(1):81-91

The aim of this study was to examine propositions stemming from Self-Determination Theory (SDT) that contend motivational consequences vary as a function of different regulations in the exercise domain. Participants (N = 276; n = 98 men; n = 178 women) completed inventories assessing exercise regulations, current exercise behavior, and behavioral intentions to continue exercising for the next 4 months and the effort and importance associated with exercise participation. Bivariate analyses indicated autonomous exercise regulations (identified and intrinsic) were the strongest correlates of each motivational consequence across both sexes, and introjected regulation was positively associated with exercise consequences in women. Simultaneous multiple regression analyses indicated that exercise regulations accounted for a sizeable portion of the variance across each motivational consequence in both sexes (R2adj values ranged from .20 to .53). Both regression and structure coefficients revealed that introjected regulation was a stronger motivational force in women than men, and identified regulation was the most important predictor of all three motivational consequences in both sexes. Collectively, these findings suggest that exercise regulations differentially predict motivational consequences across sexes, and future research using this theoretical framework for examining motivational issues pertinent to the exercise domain appears warranted.  相似文献   

Books,Bytes, and Buildings: The Academic Library's Unique Role in Improving Student Success     

Amanda Nichols Hess  Katie Greer  Shawn V. Lombardo  Adriene Lim 《图书馆管理杂志》2015,55(8):622-638

Student persistence and completion are paramount in higher education, and institutions are employing targeted programs and initiatives to address these concerns. The academic library can play an especially important role in these efforts, given its unique interdisciplinary mission and its integrated instructional programs. With a foundation in both higher education and library and information science literatures, this article describes how one academic library engaged in cross-campus programs, partnerships, and initiatives to contribute to student success efforts. Other libraries may find these examples useful as they consider how to frame their work in the context of their institutions’ student persistence efforts.  相似文献   

Exploring the Impact of Prior Experiences in Non-Formal Education on My Pedagogy of Teacher Education     

Shawn Michael Bullock 《Studying Teacher Education》2014,10(2):103-116

The purpose of this article is to use self-study methodology to analyze critically the impact of 30 years of non-formal education on my development as a teacher educator. I begin within a particular conception of self-study research and make a case for situating martial arts as non-formal education. The data for this article are presented as a series of episodes, in which I write a short paragraph about each phase in my development as a martial artist and comment on my approach to learning and teaching, where appropriate, during each episode. At the end of the article, I draw several links to self-study literature and to my own understanding of teacher education. In so doing, I demonstrate the value of examining the impact of non-formal education experiences as a teacher educator.  相似文献   

Microfluidic devices fitted with “flowver” paper pumps generate steady,tunable gradients for extended observation of chemotactic cell migration     

Scott A. Baldwin  Shawn M. Van Bruggen  Joseph M. Koelbl  Ravikanth Appalabhotla  James E. Bear  Jason M. Haugh 《Biomicrofluidics》2021,15(4)

Microfluidics approaches have gained popularity in the field of directed cell migration, enabling control of the extracellular environment and integration with live-cell microscopy; however, technical hurdles remain. Among the challenges are the stability and predictability of the environment, which are especially critical for the observation of fibroblasts and other slow-moving cells. Such experiments require several hours and are typically plagued by the introduction of bubbles and other disturbances that naturally arise in standard microfluidics protocols. Here, we report on the development of a passive pumping strategy, driven by the high capillary pressure and evaporative capacity of paper, and its application to study fibroblast chemotaxis. The paper pumps—flowvers (flow + clover)—are inexpensive, compact, and scalable, and they allow nearly bubble-free operation, with a predictable volumetric flow rate on the order of μl/min, for several hours. To demonstrate the utility of this approach, we combined the flowver pumping strategy with a Y-junction microfluidic device to generate a chemoattractant gradient landscape that is both stable (6+ h) and predictable (by finite-element modeling calculations). Integrated with fluorescence microscopy, we were able to recapitulate previous, live-cell imaging studies of fibroblast chemotaxis to platelet derived growth factor (PDGF), with an order-of-magnitude gain in throughput. The increased throughput of single-cell analysis allowed us to more precisely define PDGF gradient conditions conducive for chemotaxis; we were also able to interpret how the orientation of signaling through the phosphoinositide 3-kinase pathway affects the cells’ sensing of and response to conducive gradients.  相似文献   

tetrad: A Set of Stata Commands for Confirmatory Tetrad Analysis     

Shawn Bauldry  Kenneth A. Bollen 《Structural equation modeling》2016,23(6):921-930

This article provides a brief overview of confirmatory tetrad analysis (CTA) and presents a new set of Stata commands for conducting CTA. The tetrad command allows researchers to use model-implied vanishing tetrads to test the overall fit of structural equation models (SEMs) and the relative fit of two SEMs that are tetrad-nested. An extension of the command, tetrad_matrix, allows researchers to conduct CTA using a sample covariance matrix as input rather than relying on raw data. Researchers can also use the tetrad_matrix command to input a polychoric correlation matrix and conduct CTA for SEMs involving dichotomous, ordinal, or censored outcomes. Another extension of the command, tetrad_bootstrap, provides a bootstrapped p value for the chi-square test statistic. With Stata’s recently developed commands for structural equation modeling, researchers can integrate CTA with data preparation, likelihood ratio tests for model fit, and the estimation of model parameters in a single statistical software package.  相似文献
