East Asian countries have achieved high levels of mathematics competency. This study investigated classroom activities of East Asian countries based on the idea that different learning experiences lead to gaps in academic outcomes. The main purposes of this study were: (1) to identify the features of classroom activities in the four East Asian countries of Chinese Taipei, Hong Kong, Japan, and South Korea and the two non-Asian countries of Hungary and England, (2) to determine whether or not there are predominant features of classroom activities shared in East Asia, and (3) to verify whether or not the perceptions of classroom activities between teachers and students are consistent with each other. The data was gathered from the Student Questionnaire and the Teacher Questionnaire in TIMSS 2007. Descriptive statistics and Pearson's chi-square tests were employed to examine classroom activities in the six countries. The results indicated that, compared to traditional mathematics activities, the activities related to reform mathematics were not more likely to be deemphasized in each East Asian country. Also, with respect to reformed mathematics activities, all East Asian countries did not necessarily emphasize them less than the two non-Asian countries. Furthermore, in the frequencies of all ten activities, statistically significant differences existed between all six countries as well as within the East Asian countries. Lastly, it was found that in numerous instances, there were differences in perceptions of classroom activities between teachers and students within a country. Based on the findings, this study suggested not to regard educational practice in East Asia as traditional and to over-simplify it by the label 'East Asian style.' However, further studies are needed on various aspects of classroom practice, except for classroom activities, in East Asia. In addition, this study argued that both the views of students and teachers should be considered together in the study for educational practice. Moreover, it is suggested that future studies investigate the relationships of discrepancies between teachers and students with students' learning and achievement.

We present techniques for joint modeling of binomial and rank response data using the Bayesian paradigm for inference. The motivating application consists of results from a series of assessments on several primate species. Among 20 assessments representing 6 paradigms, 6 assessments are considered to produce a rank response and the remaining 14 are considered to have a binomial response. In order to model each of the 20 assessments simultaneously, we use the popular technique of data augmentation so that the observed responses are based on latent variables. The modeling uses Bayesian techniques for modeling the latent variables using random effects models. Competing models are specified in a consistent fashion which easily allows comparisons across assessments and across models. Non-local priors are readily admitted to enable more effective testing of random effects should Bayes factors be used for model comparison. The model is also extended to allow assessment-specific conditional error variances for the latent variables. Due to potential difficulties in calculating Bayes factors, discrepancy measures based on pivotal quantities are adapted to test for the presence of random effects and for the need to allow assessment-specific conditional error variances. In order to facilitate implementation, we describe in detail the joint prior distribution and a Markov chain Monte Carlo (MCMC) algorithm for posterior sampling. Results from the primate intelligence data are presented to illustrate the methodology. The results indicate substantial paradigm-specific differences between species. These differences are supported by the discrepancy measures as well as model posterior summaries. Furthermore, the results suggest that meaningful and parsimonious inferences can be made using the proposed techniques and that the discrepancy measures can effectively differentiate between necessary and unnecessary random effects. The contributions should be particularly useful when binomial and rank data are to be jointly analyzed in a parsimonious fashion.

Para tanto, foram estudados 185 pares de modelos, divididos em 4 grupos: Grupo 1 (composto por 41 pares com Oclusão Normal, sendo 20 do gênero masculino e 21 do gênero feminino); Grupo 2 (composto por 44 pares com má oclusão de Classe I, divisão 1, sendo 22 do gênero masculino e 22 do gênero feminino); Grupo 3 (composto por 54 pares com má oclusão de Classe II, sendo 28 do gênero masculino e 26 do gênero feminino) e Grupo 4 (composto por 46 pares com Classe III, sendo 23 do gênero masculino e 23 do gênero feminino). Observou-se que não ocorreu dimorfismo sexual entre as discrepâncias de tamanho dentário e os diferentes tipos de oclusão dentária; as proporções estabelecidas por Bolton não se aplicaram ao grupo com Oclusão Normal; na Oclusão Normal, Classe I, Classe II e Classe III, houve um predomínio de excesso dentário total (RAZ12) no arco inferior; na Classe I houve uma igualdade na distribuição de excesso dentário anterior (RAZ6) nos arcos superior e inferior; na Oclusão Normal, Classe II e Classe III, ocorreu um predomínio de excesso dentário anterior (RAZ6) no arco inferior, em relação ao arco superior; os excessos dentários não contribuíram na ocorrência das más oclusões e; as discrepâncias total e anterior (RAZ12 e RAZ6) não interferiram diretamente nas larguras e comprimentos dos arcos, bem como no posicionamento dos dentes anteriores. / The general purpose of this study was to evaluate tooth size discrepancy in normal occlusion and in different malocclusion types and its relationship to measurements which determine arch form and anterior tooth positioning. One hundred and eighty five sets of casts of leucoderms were divided into four groups: Group 1 (consisted of 41 pairs of models with Normal Occlusion, 20 males and 21 females); Group 2 (consisted of 44 pairs of models with Class I malocclusion, 22 males and 22 females); Group 3 (consisted of 54 pairs of models with Class II, div. 1, malocclusion, 28 males and 26 females) and Group 4 (consisted of 46 pairs of models with Class III malocclusion, 23 males and 23 females). No sexual dimorphism was observed between tooth size discrepancies and different types of dental occlusion; the proportions stated by Bolton were not applied to the Normal Occlusion group; in Normal Occlusion, Class I, Class II and Class III there was an overall ratio excess in the lower arch; in Class I there was an equal anterior excess distribution in upper and lower arches; in Normal Occlusion, Class II and Class III there was a prevalent incidence of anterior ratio excess in lower arch; upper arch excess did not contribute to malocclusion occurrence and overall and anterior discrepancies did not interfere with arch width and length, as well as with anterior tooth positioning.

The purpose of this study was to examine the influence of attributional style, sex roles, and sex-role self-discrepancy in the relationship between gender and depression. Epidemiological studies report a higher incidence of depression among women then men (approximately 2:1). Among the various theories suggested to explain this gender difference, sex roles, attributional style, and self-discrepancy have been conceived as possible explanations. The relationship between gender and depression may be better understood through examining the possible contribution of these three independent variables. To examine these theories, a sample of 130 subjects was drawn from clients at the USU Counseling Center, the USU Community Clinic, the Logan Regional Hospital, and students from an introductory psychology class at USU. Participation was based on voluntary informed consent of the subjects and approval of the above mentioned institutions. Each subject completed the Beck Depression Inventory (BDI), Extended Attributional Style Questionnaire (EASQ), and a revised version of the short Bern Sex-Role Inventory (SBSRI) measuring ideal versus actual self. Path analysis was used to examine the sequence of the relationships presumed by the androgyny model, congruence model, and masculinity model. Neither sex role was found to correlate significantly with depression. Overall, the directions of the path coefficients best supported the androgyny model, but these coefficients were too weak to explain the variance. Attributional style was related to depression, but no gender difference was found in the correlation between attributional style and depression. The correlation coefficient between feminine self-discrepancy and depression was positive but statistically insignificant for the females from the clinical sample and very small for females from the student sample. Overall, attributional style, sex-roles, and self-discrepancy in sex-role characteristics were not found to contribute to the higher rate of depression in women.

Health organizations around the world, from international bodies of government to local advocacy groups, are pushing the benefits of breastfeeding. While this is commendable, no study has ever been completed to assess on a regional scale the available policy options and their effectiveness at producing increased breastfeeding rates. It is my contention that five key factors influence the effectiveness of breastfeeding policies in Europe; Acceptance of public breastfeeding, maternity resource commitment, legal protection of breastfeeding in public and business space, a united voice in favor of breastfeeding, and limitations to formula advertisements in hospitals on media outlets. These five factors influence how successfully mothers navigate public and private space as they choose to breastfeed their children. In my effort to assess the contextual factors and policies that create an environment conducive to long term breastfeeding rates I am also interested in discovering a set of factors that do not increase the economic vulnerability of women. The emperical analysis derived from data from the WomanStats Database found that a combination of five conditions; social acceptance of public breastfeeding, maternal resource commitment, legal protection of breastfeeding, united voice in favor of breastfeeding, and laws regulating the sale of formula were all necessary in order to produce higher breastfeeding rates in Europe. The data also shows that when countries pursue these five factors female income disparity is not negatively impacted.

Yes / Introduction: Discrepancy scores reflecting the difference between parallel ratings made by people living with dementia (PwD) in the mild-to-moderate stages and by their informants provide a way to investigate awareness of functional ability in relation to activities of daily living (ADL). Methods: Two measures of ADL (Functional Activities Questionnaire; Dependence Scale) were completed by 1,227 PwD and their informants in the IDEAL cohort study baseline assessment. Self-rated and informant-rated scores were used to calculate discrepancies, which were used as an indicator of awareness of functional ability. Smaller discrepancy scores were considered to reflect greater awareness on the part of PwD. PwD completed questionnaires on depression, personality, comorbidities, neuropsychiatric symptoms, and completed a measure of cognition. Informants provided ratings of stress. Univariable and multiple regressions were used to investigate factors related to ADL discrepancy. Results: A similar pattern of associations were found for both ADL discrepancy scores. Smaller discrepancy scores were associated with higher levels of depression, higher neuroticism, fewer neuropsychiatric symptoms, higher comorbidity, lower carer stress, and receipt of less than 1 hour of care per day from the informant. Discussion/Conclusion: There was a clear pattern of factors that were associated with greater awareness for both measures of functional ability. These factors associated with smaller discrepancy scores could be used to identify PwD who might benefit from targeted interventions to support their independence. / Economic and Social Research Council (ESRC) and the National Institute for Health and Care Research (NIHR) grant ES/L001853/2; Alzheimer’s Society as a Centre of Excellence, grant number 348, AS-PR2-16-001

Yes / Introduction: The discrepancy between caregiver-ratings and self-ratings of abilities is commonly used to assess awareness in people with dementia. We investigated the contribution of caregiver and dyadic characteristics to the difference in perspective between caregiver-informants and people with dementia about difficulties experienced, when considering awareness of condition. Methods: We conducted exploratory cross-sectional analyses using data from the IDEAL cohort. Participants were 1,038 community-dwelling people with mild-to-moderate dementia, and coresident spouse/partner caregivers. The Representations and Adjustment to Dementia Index (RADIX) checklist reporting difficulties commonly experienced in dementia was completed by 960 caregiver-informants and 989 people with dementia. Difference in scores was calculated for 916 dyads. Demographic information, cognition, informant-rated functional ability and neuropsychiatric symptoms were recorded for the person with dementia. Self-reported data were collected on mood, comorbidity, religion, importance of religion, relationship quality, and caregiver stress. Results: For most dyads, caregivers reported more RADIX difficulties than people with dementia. Caregiver RADIX ratings were more closely associated with informant-rated functional ability and neuropsychiatric symptoms than with cognition. More RADIX difficulties and higher stress were reported by female caregivers. Greater RADIX difference was associated with more caregiver stress, and older age but less depression in people with dementia. Conclusion: Few dyadic characteristics were important, but caregiver stress was higher where caregivers reported more RADIX difficulties and/or the difference in perspective was greater, whereas partners with dementia reported better mood. In addition to offering information about awareness of condition, the caregiver rating and difference in perspectives could indicate where more support is needed. / The author(s) declare financial support was received for the research, authorship, and/or publication of this article.
