On the Correspondence between the Latent Growth Curve and Latent Change Score Models     

Sarfaraz Serang  Kevin J. Grimm  Zhiyong Zhang 《Structural equation modeling》2019,26(4):623-635

There has been a great deal of work in the literature on the equivalence between the mixed-effects modeling and structural equation modeling (SEM) frameworks in specifying growth models (Willett &; Sayer, 1994). However, there has been little work on the correspondence between the latent growth curve model (LGM) and the latent change score model (see Grimm, Zhang, Hamagami, &; Mazzocco, 2013 Grimm, K. J., Zhang, Z., Hamagami, F., &; Mazzocco, M. M. (2013). Modeling nonlinear change via latent change and latent acceleration frameworks: Examining velocity and acceleration of growth trajectories. Multivariate Behavioral Research, 48, 117–143.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). We demonstrate that four popular variants of the latent change score model – the no change, constant change, proportional change, and dual change models – have LGM equivalents. We provide equations that allow the translation of parameters from one approach to the other and vice versa. We then illustrate this equivalence using mathematics achievement data from the National Longitudinal Survey of Youth.  相似文献   

Territorial behavior of laboratory rats under conditions of peripheral anosmia     

Kevin J. Flannelly  Donald H. Thor 《Learning & behavior》1976,4(3):337-340

Two experiments investigated the influence of peripheral anosmia with zinc sulfate solution on aggressive and nonaggressive behaviors of rats in the colony intrusion paradigm. Experiment I was a replication of a previous observation that anosmic intruders arenot attacked by resident males. No significant differences were found in aggressive response to normal or anosmic intruders. Experiment II tested colony residents under normal and anosmic conditions for aggressive and nonaggressive response to intruders. The results were in agreement with previous reports that anosmia abolishes differential responding between males and females as well as all aggressive acts normally directed against unfamiliar males.  相似文献   

African Americans’ Perception of Mental Health Professions     

Kevin?A.?FallEmail author  Justin?E.?Levitov  Latoya?Anderson  Harold?Clay 《International journal for the advancement of counseling》2005,27(1):47-56

This study explored African-Americans perceptions of various mental health professions through the ranking of confidence levels across five case vignettes of varying psychiatric severity. Results indicated that African-Americans viewed psychologists and doctoral level licensed professional counselors with similar levels of confidence and ranked doctoral level licensed professional counselors above masters level counselors in every case example. Congruent with previous studies, the African American sample was confident in counselors ability to treat less severe cases and less confident in their ability to treat more severe cases.  相似文献   

Effects of a combined inversion and plantarflexion surface on knee and hip kinematics during landing     

Kevin A. Valenzuela  Divya Bhaskaran  Cicily Hummer  Antonio Schefano 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(4):429-439

Although landing in a plantarflexion and inversion position is a well-known characteristic of lateral ankle sprains, the associated kinematics of the knee and hip is largely unknown. Therefore, the purpose of this study was to examine the changes in knee and hip kinematics during landings on an altered landing surface of combined plantarflexion and inversion. Participants performed five drop landings from 30 cm onto a trapdoor platform in three different conditions: flat landing surface, 25° inversion, or a combined 25° plantarflexion and 25° inversion. Kinematic data were collected using a seven camera motion capture system. A 2 × 3 (leg × surface) repeated measures ANOVA was used for statistical analysis. The combined surface showed decreased knee and hip flexion range of motion (ROM) and increased knee abduction ROM (p < 0.05). The altered landing surface creates a stiff landing pattern where reductions in sagittal plane motion are transferred to the frontal plane, resulting in increased knee abduction. A stiff landing pattern is frequently related to increased risk of anterior cruciate ligament injury. It may be beneficial for athletes at risk to train for alternate methods of increasing their sagittal plane motion of the knee and hip with active knee or trunk flexion.  相似文献   

Further evidence for the efficacy of an evidence-based,small group,literacy intervention program for young struggling readers

Abstract

An earlier series of pilot studies and small-scale experimental studies had previously provided some evidence for the efficacy of a small group early literacy intervention program for young struggling readers. The present paper provides further evidence for efficacy based on a much larger sample of young, socially disadvantaged, at-risk readers. The participants comprised 14 successive intakes of Year 1 and Year 2 students into small group remedial literacy intervention programs hosted by two charitably run tutorial centres. In each semester, over the years 2005–2011, eight students (on average) attended each centre for one hour, for four days per week, for 15 weeks. Pre- and post-test assessment data on eight measures of early literacy performance were available on up to 194 students who completed the program. Substantial and statistically significant gains were evident on all literacy measures with large effect sizes. These results provide further evidence for the efficacy of the small group literacy intervention program.  相似文献   

New and rare lignicolous hyphomycetes from Zhejiang Province, China     

Wongsawas M  Wang HK  Hyde KD  Lin FC 《Journal of Zhejiang University. Science. B》2008,9(10):797-801

Sporidesmiopsis zhejiangensis sp. nov. and Spadicoides americana were found on submerged wood from streams in Zhejiang Province, China. Sporidesmiopsis zhejiangensis is characterized by obclavate to fusiform, 5-6-distoseptate, versicolorous, verruculose conidia with an apical mucilaginous sheath. Spadicoides americana is a new record to China. These taxa are described and illustrated, and morphological differences between these species and their similar species were summarized.  相似文献   

Effects of Short-Term Training On Residence Hall Assistants     

Kevin M. Mitchell  Stanford E. Rubin  Jerold D. Bozarth  Thomas J. Wyrick 《Counselor Education & Supervision》1971,10(4):310-318

Inasmuch as undergraduate residence hall assistants are being called upon more frequently to counsel students in social-personal problems and little training specific to this function has been given in the past, there is a need to develop an effective but brief training program leading to increased counseling effectiveness. Six hours of specialized training which focused on counselor accurate empathy enabled eight randomly chosen undergraduate resident assistants to increase their levels of accurate empathy significantly higher than a matched control group which received no training. In addition, the experimental Ss also demonstrated somewhat higher levels of counselor warmth.  相似文献   

Student researchers in the middle: using visual images to make sense of inclusive education     

Julianne Moss  Joanne Deppeler  Lesley Astley  Kevin Pattison 《Journal of Research in Special Educational Needs》2007,7(1):46-54

Using 'visual narrative' theoretically and practically, this paper explores issues of inclusive education, during a period of curriculum reform and renewal in Australia. In Australia, the middle years of schooling, Years 5 to 9, are well researched and known as a period when students disengage with learning and participation in schooling. Research in the middle years affirms the importance of engaging with 'student voice'. In this special edition, we are aiming to highlight how the use of visual imagery can be a rich source of understanding, illustrating students' self-knowledge of schooling. Methodologically we refer to our research approach as 'visual narrative'. Other writers in this edition use the term 'photo voice'. For researchers it is important to highlight the differing orientations that 'visual narrative' and 'photo voice' signify. The terms are not mutually exclusive but highlight differing research possibilities and emphasis. Our argument, through the use of visual narrative produced by middle years' students, is that visual texts open out some innovative possibilities for understanding inclusive education and supporting new relationships with our research community. Such approaches are not new; however, in a field such as special education that purports to support marginalised groups, liberatory research methods are under-represented. This paper aims to open out these discussions and provide a way forwards for teachers and researchers interested in breaking apart why it is that inclusive education remains a never-ending struggle.  相似文献   

Participation,Perplexity and Plurality: Exploring the Shared Reading of a ‘Difficult’ Poem     

Susan Jones  Kevin Harvey 《Changing English: An International Journal of English Teaching》2020,27(1):34-49

ABSTRACT

In this article, we explore how adults in a community shared reading group discuss the notoriously difficult poem ‘The Emperor of Ice-Cream’ by the American poet Wallace Stevens. Drawing on Hannah Arendt’s notion of action, we explore how participants negotiate the poem, actively constructing meanings from their shared personal experiences rather than simply reading off meanings contained in and bounded by the poem, a text which continues to be divisively contested by literary ‘experts’. In enabling them to act collectively in such a purposive and immersive fashion, shared reading, we suggest, constitutes a public space where participants experience the plurality that Arendt argues is central to the human condition. At a time when tolerance of difference has been compromised by divisive politics, a focus on the collaborative aspect of shared reading contributes to a greater understanding of the role it can play in supporting inclusive, participatory arts practices in communities.  相似文献   

Student understanding of the volume,mass, and pressure of air within a sealed syringe in different states of compression     

Kevin Charles De Berg 《科学教学研究杂志》1995,32(8):871-884

Problem-solving strategies in the physical sciences have been characterized by a dependence on algorithmic techniques often devoid of any reasoning skills. The purpose of this study was to examine student responses to a task relating to Boyle's Law for gases, which did not demand the use of a mathematical equation for its solution. Students (17- to 18-year-olds) in lower sixth form from two colleges in the Leeds district of Yorkshire in England were asked to respond to a task relating to pressure and volume measurements of air within a sealed syringe in different states of compression. Both qualitative and quantitative tasks for the sealed syringe system were examined. It was found that 34% to 38% of students did not understand the concepts of volume and mass, respectively, of a gas under such circumstances. Performance on an inverse ratio (2:1) task was shown to depend on gender and those students who performed well on the 2:1 inverse ratio task did not necessarily perform well on a different inverse ratio task when an arithmetic averaging principle was present. Tasks which draw upon qualitative knowledge as well as quantitative knowledge have the potential to reduce dependence on algorithms, particularly equation substitution and solution. The implications for instructional design are discussed.  相似文献
