Comparing journal and paper level classifications of science

The classification of science into disciplines is at the heart of bibliometric analyses. While most classifications systems are implemented at the journal level, their accuracy has been questioned, and paper-level classifications have been considered by many to be more precise. However, few studies investigated the difference between journal and the paper classification systems. This study addresses this gap by comparing the journal- and paper-level classifications for the same set of papers and journals. This isolates the effects of classification precision (i.e., journal- or paper-level) to reveal the extent of paper misclassification. Results show almost half of papers could be misclassified in journal classification systems. Given their importance in the construction and analysis of bibliometric indicators, more attention should be given to the robustness and accuracy of these disciplinary classifications schemes.  相似文献   

Cooperating Teachers' Perspectives Under Scrutiny: A comparative analysis of Australia and Canada     

Jane Mitchell  Joce Nuttall 《Asia-Pacific Journal of Teacher Education》2007,35(1):5-25

The ways in which cooperating teachers give shape and meaning to their work in practicum settings is one of the most critical elements of initial teacher education. This international comparison draws upon surveys of Australian and Canadian cooperating teachers. The global contrast highlights taken‐for‐granted assumptions in local settings that in some instances are cause for celebration and in other instances concern. The comparison of the two settings illustrates, among other things: some striking similarities in the profiles of cooperating teachers; important differences with respect to the cooperating teachers' preparation and remuneration for their role in practicum settings; and deeper complexities regarding the relationship between schools and universities.  相似文献   

The relationship of exposure to childhood sexual abuse to other forms of abuse,neglect, and household dysfunction during childhood   总被引：3，自引：0，他引：3

OBJECTIVE: This study assesses the relationship of childhood sexual abuse (CSA) to nine other categories of Adverse Childhood Experiences (ACEs), including childhood abuse, neglect, and multiple types of household dysfunction. METHODS: Retrospective cohort study data were collected from 17,337 adult health plan members who responded to a survey questionnaire. Regression models adjusted for age, race, and education were used to estimate the strength of the association of CSA to each of the other nine ACEs and a graded relationship between measures of the severity of CSA and the number of other ACEs (ACE score). RESULTS: CSA was reported by 25% of women and 16% of men. In comparison with persons who were not exposed to CSA, the likelihood of experiencing each category of ACE increased 2- to 3.4-fold for women and 1.6- to 2.5-fold for men (p < 0.05). The adjusted mean ACE score showed a significant positive graded relationship to the severity, duration, and frequency of CSA and an inverse relationship to age at first occurrence of CSA (p < 0.01). CONCLUSIONS: CSA is strongly associated with experiencing multiple other forms of ACEs. The strength of this association appears to increase as the measures of severity of the CSA increases. The understanding of the interrelatedness of CSA with multiple ACEs should be considered in the design of studies, treatment, and programs to prevent CSA as well as other forms of ACEs.  相似文献   

Class,Culture and Agency: Researching parental voice   总被引：3，自引：0，他引：3  

Carol Vincent  Jane Martin 《Discourse: Studies in the Cultural Politics of Education》2002,23(1):108-127

This paper explores the differential possession and deployment of social, cultural and material resources by parents, and the effect of these processes on their willingness and ability to be involved with and intervene in their children's school life--what we have called 'parental voice'. The data presented here are drawn from a study of parents at two secondary schools, a subsample of data from a larger study involving six schools. We consider the social positioning and behaviour of three cohorts of parents, those demonstrating high, low and intermediate levels of intervention in the school. Our conclusions stress both the similarities and differences in parents' experience of voice. Certainly, parental access to and deployment of a number of social resources significantly affected how often, how easily and over what range of issues they approached the school. However, we also describe the overall character of parental voice in these two schools as individual, cautious and insecure.  相似文献   

Learning from video modeling examples: does gender matter?     

Vincent Hoogerheide  Sofie M. M. Loyens  Tamara van Gog 《Instructional Science》2016,44(1):69-86

Online learning from video modeling examples, in which a human model demonstrates and explains how to perform a learning task, is an effective instructional method that is increasingly used nowadays. However, model characteristics such as gender tend to differ across videos, and the model-observer similarity hypothesis suggests that such characteristics may affect learning. Therefore, this study investigated whether the effectiveness of learning how to solve a probability calculation problem from video modeling examples would vary as a function of the model’s and observer’s gender. In a 2 (Model: Female/Male) × 2 (Observer: Female/Male) between-subject design, 167 secondary education students learned how to solve probability calculation problems by observing video modeling examples. Results showed no effects of Model or Observer gender on learning and near transfer. Male students reported higher self-efficacy than female students. Compared to a female model, observing a male model enhanced perceived competence more from pretest to posttest, irrespective of observers’ gender. Furthermore, learning from a male model was less effortful and more enjoyable for male students than for female students. These results suggest that gender of both model and observer can matter in terms of affective variables experienced during learning, and that instructional designers may want to consider this when creating (online) learning environments with video modeling examples.  相似文献   

Stimulus-reinforcer interactions in Pavlovian conditioning of pigeons: Implications for selective associations     

Kimron L. Shapiro  W. J. Jacobs  Vincent M. LoLordo 《Learning & behavior》1980,8(4):586-594

In a Pavlovian procedure, groups of pigeons were presented with a compound auditory-visual stimulus that terminated with either response-independent electric shock or food. In a subsequent test, the tone CS was dominant in aversive conditioning, reliably eliciting conditioned head raising and prancing. The red light CS was dominant in appetitive conditioning, reliably eliciting pecking. This result was replicated in a second experiment, in which trials were widely spaced. Pour additional groups of pigeons received pairings of the separate element CSs with the USs. Red light, but not tone, was an effective CS in appetitive conditioning, whereas tone, but not red light, was effective in aversive conditioning. There was no discriminative responding in zero-contingency control groups. Several theoretical accounts of these data are discussed.  相似文献   

Cross-modality contrast: Exteroceptive context habituation enhances taste neophobia and conditioned taste aversions     

Denis Mitchell  William Winter  Terrie Moffitt 《Learning & behavior》1980,8(4):524-528

The relationship between absolute and relative stimulus novelty was examined within the context of the conditioned taste aversion paradigm in which the relative novelty of the conditioned interoceptive stimulus was manipulated by differential exteroceptive context habituation. Rats received similar isolation histories but either 5 or 30 days of habituation to the test environment prior to treatment. One group was administered lithium chloride following saccharin consumption, a second group was administered isotonic saline following saccharin consumption, and a third group was administered saline after water consumption. The animals habituated for 30 days exhibited greater conditioned avoidance and greater neophobic avoidance of saccharin than did animals habituated for only 5 days. The results are interpreted in terms of a cross-modality stimulus contrast effect which implicates context habituation as an important parameter of both taste neophobia and taste aversion learning.  相似文献   

Sexual victimization and adolescent weight regulation practices: a test across three community based samples     

Thompson KM  Wonderlich SA  Crosby RD  Mitchell JE 《Child abuse & neglect》2001,25(2):291-305

OBJECTIVE: This study had four objectives: 1) to examine the association between sexual victimization and weight regulation across three samples of adolescent girls, 2) to assess whether sexual victimization is associated with more extreme forms of weight regulation in girls, 3) to discern whether sexual victimization has implications for the use of multiple forms of weight regulation, and 4) to address the role of physical victimization in explaining these relationships. METHOD: Data from three separate samples of 9th-12th graders were used to test these hypotheses. Girls from the upper Midwest responded to survey questions related to victimization and weight regulation in a largely urban sample (N = 2,086), a rural sample (N = 2,629), and a statewide sample (N = 966). RESULTS: Logistic regression revealed that sexual victimization was consistently associated with weight regulation in adolescent girls, independent of the effects of physical victimization. In the urban sample, being sexually victimized was associated with an increase in the probability of purging by 18% relative to not being sexually victimized. Sexual victimization was associated more strongly with extreme forms of weight regulation and significantly discriminated whether girls would choose multiple weight regulation forms. CONCLUSIONS: Sexual victimization contributes unique variance to the probability that girls will practice weight regulation techniques. Data from three independent samples confirms that being violated sexually places girls at risk for various health compromising eating behaviors.  相似文献   

Testing the effectiveness of handwriting interventions: introduction to the special issue     

Teresa Limpo  Rui A. Alves  Vincent Connelly 《Reading and writing》2018,31(6):1249-1253

This special issue was born within the COST Action IS1401ELN—Strengthening Europeans’ Capabilities by Establishing the European Literacy Network, with the major goal of disseminating evidence-based practices to promote handwriting and motivate researchers to move this research field forward. This issue includes five articles testing a different range of interventions to promote handwriting in students with and without disabilities from kindergarten to middle grades, across multiple contexts (viz., United States, Switzerland, Belgium, and Portugal). A final commentary paper closes the special issue with a discussion on the importance of acquiring fluent and legible handwriting along with the contributions and limitations of the investigations presented in the special issue.  相似文献   

Lifelong learning ecologies in online higher education: Students' engagement in the continuum between formal and informal learning     

Mitchell Peters  Marc Romero 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(4):1729-1743

Lifelong learning opportunities are readily accessible through the hybridization of digital learning contexts—from formal to informal—in today's globally networked knowledge society. As such, expanded learning opportunities generate a continuum of learning contexts and experiences mediated through digital technology. Consequently, there is an urgent need to actively examine the interconnections and complex relations between what is learned in formal university scenarios and the everyday learning that happens outside of the classroom, particularly the informal learning that is afforded through expanded and emerging digital contexts. The current research problem illustrates that expanded and emerging professional development scenarios require new pedagogical designs for empowering lifelong learners to harness the affordances of the web across both formal and informal contexts and practices. This study outlines ways in which students shape their learning ecologies in virtual contexts to support formal academic learning in online higher education. The paper presents qualitative results from a larger mixed methods interpretive case study. The multicase and multisite study examines three fully online graduate programmes in Education and Digital Technology during the 2017–18 academic year, collecting data in the form of online programme documentation, student interviews and online participant observation. Purposeful and criterion sampling were used to select 13 participants across three sites in Spain, the UK and the USA. The study was underpinned by a lifelong learning ecologies theoretical perspective to analyse learning processes across a continuum of practices and contexts. Findings illustrate how students conceive of, as well as how they organize their learning ecologies through a unique configuration of activities, digital resources and networked social support, indicating that academic programmes and teachers have an essential role in empowering student learning ecologies across contexts, recognizing past trajectories and supporting the development of valued disciplinary practices and perspectives across a continuum of learning.  相似文献
