Identifying and predicting problem behavior trajectories among pre-school children investigated for child abuse and neglect     

Woodruff K  Lee B 《Child abuse & neglect》2011,35(7):491-503

Objective

Young children involved with child welfare services are at high risk for behavior problems. This study aims to identify externalizing behavior paths that preschoolers in this high-risk population follow over a 6 year period, and the predictors of membership in normative and problematic pathways.

Methods

Using data from the National Study of Child and Adolescent Well-being (NSCAW), the sample included 246 4-year-olds who remained home after investigation. Latent class growth analysis (LCGA) was used to estimate the number, size, and shape of subgroups of preschoolers following distinct behavioral pathways. Early predictors of membership in the resulting groups were then examined.

Results

Four groups of preschool children following distinct behavior trajectories over 6 years were identified. Weighted results show that more than half (61%) of the children followed a low/normal problem behavior trajectory while just over one tenth (12%) were on a persistent high trajectory, remaining in the clinical range throughout the study. Improving (23%) and worsening (4%) problem behavior groups were also identified. Internalizing problems, attention problems, child ethnicity, and maltreatment type reported at age 4 predicted membership in the trajectory groups.

Conclusions

Internalizing behavior problems and maltreatment type may distinguish preschool children who are more likely to experience worsening or persistent problematic externalizing behaviors from those likely to follow a normal behavior trajectory.

Practice implications

Identifying early indicators of externalizing behavior problems and addressing them with evidence-based interventions to reduce negative behaviors may avert long-term negative outcomes.  相似文献   

On Going (Way) Beyond One’s Data: A Proposal to Restrict Recommendations for Practice in Primary Educational Research Journals     

Daniel H. Robinson  Joel R. Levin  Gregory Schraw  Erika A. Patall  Earl B. Hunt 《Educational Psychology Review》2013,25(2):291-302

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate about the educational policy implications of their research. We believe that this change will be beneficial for maintaining a separation between evidence and opinion concerning the legitimate warrants of empirical research. We suggest viable accompaniments and alternatives to authors offering practical recommendations and policy speculations in primary-research journal articles. Among these is to rely on all sources of evidence, including systematic research syntheses based on the aggregated contribution of multiple research studies from different sources, with recommendations for practice tailored to specific situations so that both their validity and utility will be increased. It is hoped that our proposed policy change will initiate a conversation among researchers, editors, reviewers, and educational-policy experts with respect to the scope and purpose of primary research journal articles.  相似文献   

'I Caught the Sudden Look of Some Dead Master': Eliot's Tradition and Modern Materialism     

Adam C. Woodruff 《Culture, Theory & Critique》2013,54(2):85-100

This essay explores the relations between T. S. Eliot's concept of tradition and the ‘modern materialism’ of Walter Benjamin, Jacques Lacan and Louis Althusser, and considers the implications of this resonance for both Eliot's critical legacy and the Marxist tradition. Initially surveying the critical controversy surrounding the canonical figure of Eliot and recent attempts to reconcile his avant-garde poetics with his reactionary social thought, the essay traces the roots of Eliot's tradition in a Nietzschean critique of historicism and its development into a theory of culture. Eliot's persistent drive towards impersonality echoes (and problematises) the efforts of Benjamin, Lacan and Althusser to construct a model of the social process that incorporates the unconscious. Rather than ultimately determining a set of political positions, the ‘missed encounter’ between Eliot's tradition and ‘modern materialism’ draws to light the Hegelian historicisms that haunt materialist theories of culture.  相似文献

Young adolescent psychological need profiles: Associations with classroom achievement and well‐being     

Stephen R. Earl  Ian M. Taylor  Carla Meijen  Louis Passfield 《Psychology in the schools》2019,56(6):1004-1022

Drawing on self‐determination theory, a person‐centered methodology was adopted to identify distinct pupil profiles based on their psychological need satisfaction. A sample of 586 pupils (387 male, 199 female; mean age = 12.6, range 11–15 years old) from three secondary schools reported their psychological need satisfaction, and well‐ and ill‐being, with teachers rating pupil achievement. Hierarchical cluster analysis revealed five distinct profiles. Four profiles indicated synergy existed between the three needs, showing similar in‐group levels of satisfaction across the needs but in varying amounts. Univariate and multivariate analyses, controlling for school and taught subject, revealed the satisfied group displayed the highest classroom performance (F_4,540 = 7.03; p < 0.001; η_p² = 0.05), well‐being (F_8,1,136 = 45.63; p < 0.001; Wilk's Λ = 0.57; η_p² = 0.24) and lowest ill‐being (F_8,1,134 = 23.39; p < 0.001; Wilk's Λ = 0.74, η_p² = 0.14), whereas the dissatisfied group displayed the most adverse outcomes. The findings illustrate that the three psychological needs may operate interdependently and should be considered in combination rather than in isolation. The research offers practical insights into why pupils may function differently in classrooms and could inform targeted initiatives towards pupils with psychological need satisfaction deficits.  相似文献   

The multiple sources of workplace stress among land-grant university faculty     

Earl Smith  John L. Anderson  Nicholas P. Lovrich 《Research in higher education》1995,36(3):261-282

Workplace stress has received a fair amount of treatment in the research literature over the past decade. What has not been examined, at least not systematically, is this same phenomena inacademe. Our study looked at stress among university faculty at a land-grant university located in the western region of the U. S. Analyses from the self-assessment mail survey (N = 786) reveals that faculty in the Hard Pure Nonlife (e. g., Astronomy, Math, Physics), Hard Applied Nonlife (e. g., Civil Engineering, Nuclear Engineering, Computer Science) and Soft Applied Life (e. g., Education Administration, Special Education) experience more stress than faculty in disciplines such as Hard Pure Life (e. g., Botany, Zoology) and Soft Pure Nonlife (e. g., English, Philosophy, Communications). Careful attention was paid to the different levels of stress reported by male and female faculty, with women professors reporting a higher level of stress than their male counterparts. We provide an assessment and explanation for this finding. Research ends with several proposals for individual faculty, department chairs and academic administrators for addressing the problem of workplace pressure and work overload.  相似文献   

Autoshaping of initial feeding and drinking reactions in newly hatched chicks     

Guy Woodruff  M. David Starr 《Learning & behavior》1978,6(3):265-272

Newly hatched chicks were force-fed food and water throughout rearing, and food, water, or sand reinforcers during exposure to an omission-training procedure. The chicks were thus prevented from performing approach and contact responses to the reinforcer at any time in their lives. Nevertheless, the subjects displayed approach and species-specific feeding or drinking reactions directed toward an illuminated key paired with food or water, but not with sand. Illumination of a key either uncorrelated or negatively correlated with food or water did not engender appreciable responding. Feeding and drinking reactions were topographically distinct, determined by the type of reinforcer, but were not elicited by the reinforcer. These findings support a “learned release” view of autoshaping, according to which phylogenetically preorganized behavior patterns are triggered by distal stimuli paired with biologically significant proximal stimulation, and suggest a close relationship between autoshaping and primitive instances of visual object recognition.  相似文献
