Rater‐mediated assessments are a common methodology for measuring persons, investigating rater behavior, and/or defining latent constructs. The purpose of this article is to provide a pedagogical framework for examining rater variability in the context of rater‐mediated assessments using three distinct models. The first model is the observation model, which includes ecological/environmental considerations for the evaluation system. The second model is the measurement model, which includes the transformation of observed, rater response data to linear measures using a measurement model with specific requirements of rater‐invariant measurement in order to examine raters’ construct‐relevant variability stemming from the evaluative system. The third model is the interaction model, which includes an interaction parameter to allow for the investigation into raters’ systematic, construct‐irrelevant variability stemming from the evaluative system. Implications for measurement outcomes and validity are discussed. 相似文献
In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong). 相似文献
The purpose of this study was to investigate the role textbooks can play on writing complexity and lexical density as a proxy for critical thinking and ultimately learning, in relation to argumentative and summative writing when integrated with a virtual reality experience. In this study, differences in writing complexity and lexical density scores were measured across four different pedagogical modalities: VR alone, VR followed by textbook readings, textbook readings followed by VR, and textbook readings alone. Adult students, recruited from non-science-based higher education programs, responded to two prompts related to content found in the VR environments and discussed in the textbooks. The authors hypothesized that exposure to a virtual marine environment prior to responding to the writing prompts would enhance both argumentative and summative writing products, when compared to participants who only had access to the textbook experiences. Participants who were exposed to the VR environment then a textbook demonstrated significantly greater writing complexity and lexical density scores than those who had access to VR alone, or access to the text alone.
Massage therapy program directors completed an online survey to explore sexual education in massage therapy programs. The overall data suggest that program directors are supportive of sexual health education in the training of massage therapists and that such education is integrated into several aspects of their training programs. To enhance sexual health education, massage therapy programs could collaborate with specialists in sex therapy or sexuality education. Massage therapy training may need to include the following topics: working with clients who have been sexually abused, working with transsexual clients, understanding sexual arousal processes, and understanding dynamics between men and women. 相似文献
The aim of this article is to assess whether and how the CBC’s music radio programming reflects the corporation’s mandate of showcasing a diversity of music and culture. I argue that a program logic that privileges an international corporate music industry strategy persists (particularly during the peak morning and afternoon drive time programs) and limits the capacity for public radio to imagine and project alternative musical trajectories. My aspiration is to imagine CBC Music’s over-the-air radio as a residual broadcast service, one that presents novel opportunities at a time when digital and online streaming music is dominant. 相似文献
Census information of some form has been collected in Canada since the 1611 census of New France. Aboriginal people, identified
or not, have been included in these enumerations. The collection of this information has had a profound impact on Aboriginal
people and has been an element that has shaped their relationship with the dominant society. In response, Canadian Aboriginal
people have often resisted and refused to co-operate with census takers and their masters. This article is an examination
of this phenomenon focused on the censuses conducted in the post-Confederation period to the present. A census is made to
collect information on populations and individuals that can then be used to configure and shape social and political relations
between those being enumerated and the creators of the census. However, the human objects of the census are not just passive
integers and they have resisted its creation in a number of ways, including being “missing” when the census is taken, refusing
to answer the questions posed by enumerators or even driving them off Aboriginal territory. A census identifies elements of
the social order and attempts to set them in their “proper” place and those who do not wish to be part of that order may refuse
to take part. Archivists and historians must understand that the knowledge gained in a census is bound with the conditions
of own creation. This has been noted by contemporary Aboriginal researchers who often state that the archival record of their
people often distorts history and reflects the ideas and superficial observations of their Euro-Canadian creators. Changes
to the Census of Canada since 1981, have increased the participation rate and therefore changed the nature of the record.

The Children-of-Twins design was used to test whether associations between marital conflict frequency and conduct problems can be replicated within the children of discordant twin pairs. A sample of 2,051 children (age 14-39 years) of 1,045 twins was used to estimate the genetic and environmental influences on marital conflict and determine whether genetic or environmental selection processes underlie the observed association between marital conflict and conduct problems. Results indicate that genetic and nonshared environmental factors influence the risk of marital conflict. Furthermore, genetic influences mediated the association between marital conflict frequency and conduct problems. These results highlight the need for quasiexperimental designs in investigations of intergenerational associations. 相似文献
