There is mixed evidence as to whether concrete manipulatives (e.g., toy animals) are better than abstract manipulatives (e.g., counters) for teaching mathematical concepts to children. Concreteness is defined as the amount of extraneous information a manipulative provides, and in this study we aimed to unpick which dimensions of concreteness influence manipulative choice. Researchers, teachers, and parents completed a comparative judgment task comparing images of manipulatives varying in different dimensions of concreteness, selecting which they would choose to teach arithmetic to children. The findings indicated homogeneous, 3-dimensional manipulatives were the most preferred across all groups to teach arithmetic to children, regardless of more extraneous features. This contradicts research recommendations to minimize the use of concrete manipulatives due to their distractive qualities. Instead, it suggests that some concrete features may be preferred in more naturalistic contexts. More research is required to investigate how different dimensions of concreteness influence learning outcomes for children both in artificial research contexts and in practice. 相似文献

The objective assessment of the prestige of an academic institution is a difficult and hotly debated task. In the last few years, different types of university rankings have been proposed to quantify it, yet the debate on what rankings are exactly measuring is enduring.To address the issue we have measured a quantitative and reliable proxy of the academic reputation of a given institution and compared our findings with well-established impact indicators and academic rankings. Specifically, we study citation patterns among universities in five different Web of Science Subject Categories and use the PageRank algorithm on the five resulting citation networks. The rationale behind our work is that scientific citations are driven by the reputation of the reference so that the PageRank algorithm is expected to yield a rank which reflects the reputation of an academic institution in a specific field. Given the volume of the data analysed, our findings are statistically sound and less prone to bias, than, for instance, ad–hoc surveys often employed by ranking bodies in order to attain similar outcomes. The approach proposed in our paper may contribute to enhance ranking methodologies, by reconciling the qualitative evaluation of academic prestige with its quantitative measurements via publication impact. 相似文献

Differentiated thyroid carcinoma (DTC) generally has a favorable outcome. Thyroid disease, treatments, stress, and comorbidity
can compromise health-related quality of life (QoL) and indirectly weigh upon the outcome. From 2004 to 2008, we evaluated
QoL longitudinally in 128 DTC subjects. During scheduled examinations, subjects were asked to undergo a semi-structured psychiatric
interview and five rated inventories. The same examination was conducted in 219 subjects after surgery for benign thyroid
pathology. Low scores represent a better QoL. DTC and control subjects were similar in terms of age, male/female ratio, concomitant
psychopharmacological treatments, and frequency of psychiatric diseases. In DTC subjects, Billewicz scale (BS) scores showed
an increasing trend over time, especially among females. The ad hoc thyroid questionnaire (TQ) scores were similar in both
groups and did not change over time, but at the end of the study ad hoc TQ and BS were significantly related. Ad hoc TQ scores
were also related to age on entry to the study. In both male and female DTC subjects, Hamilton’s tests for anxiety (HAM-A),
but not for depression (HAM-D), showed an improving trend. At the end of the study, HAM-A and HAM-D scores were comparable
to those of the control group. HAM-A and HAM-D were both positively correlated with the stage of cancer and the time between
diagnosis and treatment. Only HAM-D correlated with age on entry to the study. Kellner symptom questionnaire (KSQ) item scores
were higher in DTC subjects than in controls. The change over time in the items including anxiety, somatization, depression,
and hostility was significant. Somatization and hostility were more significantly reduced in DTC females than in DTC males.
Hostility scores were significantly lower in DTC subjects than in controls at the end of the study. Somatization and depression
were significantly related to staging on diagnosis and age on entry to the study. Our study confirms a wide variation of illness
perception in DTC subjects, which is generally unrelated to the favorable clinical follow-up of the disease. Psychological
evaluation during long-term follow-up improved QoL scores, which reached the same levels noted in subjects with a history
of thyroid surgery for benign thyroid pathology. Our data indicate that special attention should be paid to QoL in older DTC
subjects and those with more severe staging on diagnosis. 相似文献

Abstract Anthropometry and body composition were investigated in 43 female handball players from the Italian championships, grouped according to their competitive level (elite vs. sub-elite) or their playing position [goalkeeper (n = 7), back (n = 14), wing (n = 18), or pivot (n = 4)]. The anthropometry consisted of several circumferences, lengths, widths, and skinfold measurement at six sites; the regional and total body compositions were assessed by means of dual-energy X-ray absorptiometry (DXA). One-way ANOVA was used for statistical analysis, with a Bonferroni post-hoc test where needed. The results showed that elite players have significantly lower percentages of fat and higher bone mineral content than sub-elite as well as a clear tendency to accrue more lean mass, especially in upper limbs. Overall, the physical characteristics and body composition of handball players in Italy compared unfavourably with those in other countries, suggesting a need for improved selection and training. When playing position was included in the analysis of the whole group of handball players (n = 43) significant differences were found between the stature, mass, body mass index (BMI), several skinfolds, circumferences and lengths, and total body mineral mass, lean mass and fat mass of players in different positions. Post-hoc analysis suggests that players on the wing and in goalkeeper positions differed most from one another. These findings confirm and expand on previous data about the presence of anthropometric differences within playing positions in handball. 相似文献

体育法是民法法系与普通法系在法律实践上融汇的领域。两大法系尽管存在着法律传统和法律思维上的差别,但法律实务的现实要求却跨过了这种隔阂。民法法系的体育法律师更需注意到这种两大法系的融汇趋势,从而在类似于体育赞助合同这样的体育法实务操作中汲取普通法的经验。 相似文献

Active participation in the information society requires the ability to find some order in the chaotic nature of the Web and not to get lost within the endemic presence of inaccurate, misleading, biased and false information. This article presents an approach to Information Problem Solving (IPS) – that is, finding, understanding and assessing information on the Web – and discusses a study carried out in an Italian secondary school, using an experimental and a control group. The study aimed at exploring how to best foster IPS skills, and observing whether and how IPS activities could promote the development of more general learning dispositions and competences. After a period of training with IPS activities, the experimental group showed different dispositions towards learning from a text and engaging with open-ended questions. Despite serious limitations in the depth of analysis, most students were able to reach acceptable solutions; at the same time, they felt empowered and developed an embryonic critical attitude on which it might be possible to build further. 相似文献
