Using factor analysis, we conducted an assessment of multidimensionality for 6 forms of the Law School Admission Test (LSAT) and found 2 subgroups of items or factors for each of the 6 forms. The main conclusion of the factor analysis component of this study was that the LSAT appears to measure 2 different reasoning abilities: inductive and deductive. The technique of N. J. Dorans & N. M. Kingston (1985) was used to examine the effect of dimensionality on equating. We began by calibrating (with item response theory [IRT] methods) all items on a form to obtain Set I of estimated IRT item parameters. Next, the test was divided into 2 homogeneous subgroups of items, each having been determined to represent a different ability (i.e., inductive or deductive reasoning). The items within these subgroups were then recalibrated separately to obtain item parameter estimates, and then combined into Set II. The estimated item parameters and true-score equating tables for Sets I and II corresponded closely. 相似文献
In 1988 academic unions were signatories to the first industrial award ever negotiated concerning academic salaries in Australia. In return for the 4% Second Tier increase, academics became subject to mandatory supervision and performance assessment. The wording of the award allowed a wide diversity of ways in which institutions could interpret and implement these requirements. One University's response to the award is examined.
In 1991 a subsequent award restructuring decision imposed the trial requirement of routine appraisal of academic staff for development only. This paper discusses the issues arising for academic staff as a result of these requirements, particularly the difficulty for an appraiser of separating the purpose of judgement from that of development, and it analyses the nature of the training needed for developmental appraisers.
It is concluded that as a result of the 1991 decision there is now a chance that academic staff development will be taken seriously if the funding implications of these requirements are honoured. 相似文献
The present work introduced a task which superimposed a tray brightness, stimulus-response contingency on previously acquired, highly successful, one-trial oddity performance. Continuing with new one-trial oddity problems, the new contingency was that responses to the odd objects were rewarded on a white tray and responses to the nonodd objects were rewarded on the black tray. Since there is no opportunity to learn specific stimuli or stimulus patterns, successful performance may be interpreted as having a conceptual basis. All monkeys achieved criterion (90% based on 18/20) and statistically significant performances (p<.001). Discussion considered the appropriate nomenclature to describe a conceptual conditional discrimination task and the necessary evidence to justify a conceptual interpretation of conditional discrimination behavior. 相似文献
Although many think, or wish to think, that racism in the United States is part of our peripheral past, contemporary discourses of racial and ethnic relations suggest otherwise. Discussions of ethnicity and race are still at the forefront of public discourse. The recent publication of news articles citing celebrity chef Paula Deen’s use of ethnophaulisms and prejudiced talk resulted in thousands of user-generated comments and responses. This article purports, then, to highlight the current discourses of racial and ethnic relations as revealed through online responses to one particular ethnophaulism used by celebrity chef Paula Deen. Important to this discussion, however, is the interesting finding that comments made by readers spoke to larger “meta” discourses of language use: Users commented about contemporary American race and racial relations and how we use (or do not use) language with specific purposes and power in mind, rather than the specific case of Paula Deen’s utterance. 相似文献
Globalization has led to an increase in United States-influenced counseling programs the world over; however, the extent to which these training models apply to other cultures is unclear. Using a sample of master’s-level counseling students studying in the Czech Republic (n?=?5), the authors conducted a phenomenological inquiry examining the experiences of European students trained in a program developed and supervised by faculty in the United States. Three themes (and potential barriers) related to English-language training programs in Central Europe included: cultural differences between faculty and students, complications related to the notion of professional identity, and concerns related to the utility of wellness-based principles in the Czech Republic. Implications for educators include cultural adaptation of training and course material as well as reframing illness perspectives through a wellness lens. 相似文献
OBJECTIVE: A cumulative risk model was used to examine the relationship among failure-to-thrive (FTT), maltreatment, and four aspects of children's development: cognitive performance (standardized testing), adaptive functioning at school, and classroom behavior (teacher report), and behavior at home (maternal report). METHOD: The sample included 193 6-year-old children and their families, recruited from pediatric clinics serving inner-city, low-income, primarily African-American families, who were part of a longitudinal investigation of child development and maltreatment. Four risk groups were formed based on their growth and maltreatment history: neither FTT nor Maltreatment, FTT Only, Maltreatment Only, and both FTT and Maltreatment. FTT was defined as a deceleration in weight gain (weight-for-age below the 5th percentile) prior to 25 months of age among children born at term with birth weight appropriate for gestational age. Maltreatment was defined as having at least one report to CPS for neglect, physical abuse and/or sexual abuse. RESULTS: Risk status was negatively associated with each of the four developmental outcomes. Children with a history of both FTT and maltreatment had more behavior problems and worse cognitive performance and school functioning than children with neither risk factor. Children with only one risk factor (either FTT or maltreatment) achieved intermediate scores. CONCLUSIONS: Findings support a cumulative risk model as being more detrimental to children's development than the presence of a single risk factor alone, consistent with theories linking the accumulation of environmental risks to negative consequences. These results underscore the importance of interventions to prevent both FTT and maltreatment during children's early years. 相似文献
Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience—within a learning session and over development—influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4–11 years) and adults searched for rewards hidden in locations with predetermined probabilities. In Experiment 1, children (n = 42) and adults (n = 32) changed strategies to maximize reward receipt over time. However, adults demonstrated greater strategy change efficiency. Making the predetermined probabilities more difficult to learn (Experiment 2) delayed effective strategy change for children (n = 39) and adults (n = 33). Taken together, these data characterize how children and adults alike react flexibly and change behavior according to incoming information. 相似文献
