Visual input during development seems crucial in tactile spatial perception, given that late, but not congenitally, blind people are impaired when skin‐based and tactile external representations are in conflict (when crossing the limbs). To test whether there is a sensitive period during which visual input is necessary, 14 children (age = 7.95) and a teenager (LM; age = 17.38) deprived of early vision by cataracts, and whose sight was restored during the first 5 months and at age 7, respectively, were tested. Tactile localization with arms crossed and uncrossed was measured. Children showed a crossing effect indistinguishable from a control group (Ns = 28, age = 8.24), whereas LM showed no crossing effect (Ns controls = 14, age = 20.78). This demonstrates a sensitive period which, critically, does not include early infancy. 相似文献

Infants have an early understanding of giving (the transfer of an item by one agent to another), but little is known about individual differences in these abilities or their developmental outcomes. Here, 9-month-olds (N = 59) showing clearer neural processing (Event-related potential, ERP) of a give-me gesture also evidenced a stronger reaction (pupil dilation) to an inappropriate response to a give-me gesture, and at 2 years were more likely to give in response to a give-me gesture. None of the differences in understanding and production of giving-related behaviors were associated with other sociocognitive variables investigated: language, gaze-following, and nongiving helping. The early developmental continuity in understanding and production of giving behavior is consistent with the great importance of giving for humans throughout the life span. 相似文献

In this paper we study the problem of classification of textual web reports. We are specifically focused on situations in which structured information extracted from the reports is used for classification. We present an experimental classification system based on usage of third party linguistic analyzers, our previous work on web information extraction, and fuzzy inductive logic programming (fuzzy ILP). A detailed study of the so-called ‘Fuzzy ILP Classifier’ is the main contribution of the paper. The study includes formal models, prototype implementation, extensive evaluation experiments and comparison of the classifier with other alternatives like decision trees, support vector machines, neural networks, etc. 相似文献

Factors influencing the intention to revisit a cultural attraction: The case study of the Museum of Modern and Contemporary Art in Rovereto 总被引:1,自引:0,他引:1
This paper analyses the different factors influencing the intention to revisit a cultural attraction with an application to the Museum for Modern and Contemporary Art (MART) in Rovereto, Italy. The empirical data were obtained from a survey undertaken in 2009 and a zero-truncated count data model is estimated. The findings reveal that sociodemographic characteristics positively influence the probability to return to the museum. Also, as reported in other studies, the temporary exhibitions offered by the museum have a significant impact with an incidence rate ratio almost twice as high. No matter how much visitors spend on accommodation, they are less likely to revisit if they travel in groups, by train or on foot, are far from their town of origin and have spent a long time visiting the museum. 相似文献

This paper highlights the challenges of assessing the value of business-to-government IT innovations for both private and public stakeholders. Due to the different backgrounds of inhomogeneous stakeholders, potential adopters of business-to-government systems have varying requirements; in particular, they address understandings of value attributed to the implementation and the usage of such systems. Incorporating specific perspectives of each stakeholder in its own domain for evaluation is vital for supporting diffusion of IT innovations. The main contribution of this paper is the development of a value assessment framework that combines the value understanding from both public and private stakeholders. Applying this framework not only allows the value assessment of business-to-government IT innovations incorporating different needs and requirements of various current stakeholders, but it also provides common and objective evaluation criteria on similar business-to-government IT innovations for potential adopters from both domains. We discuss the application of the proposed value framework in the case of e-customs systems redesign based on an example of the introduction of e-customs IT solutions in a Finnish multinational company. 相似文献

In the past few decades, there has been a sharp increase in the number of students attending higher education institutions
in Spain. Many commentators believe that this expansion is associated with greater equality of opportunities as more university
places offer greater potential for the advancement of students from poorer backgrounds. Unfortunately, this argument is not
always true. In fact, there is empirical evidence that the expansion in higher education system disproportionately benefits
children from relatively rich and well educated families. In that context, the purpose of this paper is to analyse the possible
effects of socioeconomic background on the decision to complete a degree before leaving the educational system in Spain. Taking
the data from the Spanish module data on school to work transitions, I estimate several logit models in order to detect the
influence of personal and regional characteristics on the educational decisions. The results show that, in spite of the disappearance
of universities for only the elite, socioeconomic variables heavily influence the demand for university education, so the
equality of opportunities in this educational level has not been completely achieved.

The general aim is to promote the use of individual-based models (biological agent-based models) in teaching and learning contexts in life sciences and to make their progressive incorporation into academic curricula easier, complementing other existing modelling strategies more frequently used in the classroom. Modelling activities for the study of a predator–prey system for a mathematics classroom in the first year of an undergraduate program in biosystems engineering have been designed and implemented. These activities were designed to put two modelling approaches side by side, an individual-based model and a set of ordinary differential equations. In order to organize and display this, a system with wolves and sheep in a confined domain was considered and studied. With the teaching material elaborated and a computer to perform the numerical resolutions involved and the corresponding individual-based simulations, the students answered questions and completed exercises to achieve the learning goals set. Students’ responses regarding the modelling of biological systems and these two distinct methodologies applied to the study of a predator–prey system were collected via questionnaires, open-ended queries and face-to-face dialogues. Taking into account the positive responses of the students when they were doing these activities, it was clear that using a discrete individual-based model to deal with a predator–prey system jointly with a set of ordinary differential equations enriches the understanding of the modelling process, adds new insights and opens novel perspectives of what can be done with computational models versus other models. The complementary views given by the two modelling approaches were very well assessed by students. 相似文献

Influence of a catalan peer tutoring programme on reading comprehension and self‐concept as a reader
This study relates to the results obtained in the development of reading comprehension (RC) and self‐concept as a reader in students who participated in Llegim en parella (Reading in pairs), a Catalan peer tutoring programme. The research combines a quasi‐experimental design with the use of comparison groups and pre‐tests/post‐tests for both variables; a qualitative approach is adopted by analysing the interactions in order to detect influencing factors. Statistically significant results were obtained for all students in terms of RC but only for student tutors in relation to reading self‐concept. The factors involved in the improvements identified in RC are: reading strategies, scaffolding in inferential and deep comprehension questions. Regarding self‐concept, the tutor's own role, his involvement with their tutees' progress, reading aloud and the metacognitive reflection processes, are all factors that enable us to explain the improvement in the tutor's reading self‐perception. The positive influence of peer tutoring on the development of reading competence through this programme is clearly evident. 相似文献

In this study, we explored the relationship between prospective teachers’ algebraic thinking and the questions they posed during one-on-one diagnostic interviews that focused on investigating the algebraic thinking of middle school students. To do so, we evaluated prospective teachers’ algebraic thinking proficiency across 125 algebra-based tasks and we analyzed the characteristics of questions they posed during the interviews. We found that prospective teachers with lower algebraic thinking proficiency did not ask any probing questions. Instead, they either posed questions that simply accepted and affirmed student responses or posed questions that guided the students toward an answer without probing student thinking. In contrast, prospective teachers with higher algebraic thinking proficiency were able to pose probing questions to investigate student thinking or help students clarify their thinking. However, less than half of their questions were of this probing type. These results suggest that prospective teachers’ algebraic thinking proficiency is related to the types of questions they ask to explore the algebraic thinking of students. Implications for mathematics teacher education are discussed. 相似文献

This paper draws on qualitative data from a mixed‐method study that analysed women's access to the principal role and their leadership experiences. The paper draws on a subset of interviews with 54 female head teachers in the Gauteng and North West provinces of South Africa. Since a mothering style of leadership was self‐reported by over half of the participants in our study, this paper aims to explore the diverse ways in which motherhood was constructed and the outcomes of these constructions on women. 相似文献
