Little is known about how specific iPad applications affect parent–child story‐sharing interactions. This study utilises a case‐study approach to provide an insight into the patterns of interaction, which emerge when a mother and her 33‐month‐old daughter share a self‐created, audio‐visual ‘iPad story’. Multimodal analysis allowed us to gain insights into the complex interaction patterns orchestrated in this new, personalised story‐sharing medium. We found that the app‐mediated story‐sharing context produced a harmonious and smooth interaction, achieving a coherence that is typical of ‘happy’ oral stories. We suggest that the observed interaction resembles that of experiencing a piece of art, and we highlight the need for a holistic approach to understanding the implications for research and practice of children's interactions during multimedia story sharing. 相似文献

This article reports the maintenance of one of the largest interventions conducted in St. Petersburg (Russian Federation) orphanages for children birth to 4 years using regular caregiving staff. One orphanage received training plus structural changes, another training only, and a third business as usual. The intervention produced substantial differences between these institutions on the Home Observation for Measurement of the Environment (HOME) Inventory and on the Battelle Developmental Inventory scores for children. These institutional differences in HOME scores (N = 298) and Battelle scores for children (N = 357) departing the institutions for families in St. Petersburg and the United States were maintained for at least 6 years after the intervention project. This result may be associated with certain features of the intervention and activities conducted during the follow‐up interval. 相似文献

The goal of the study was to investigate the overlap between developmental language disorder (DLD) and developmental dyslexia, identified through spelling difficulties (SD), in Russian-speaking children. In particular, we studied the role of phoneme awareness (PA), rapid automatized naming (RAN), pseudoword repetition (PWR), morphological (MA), and orthographic awareness (OA) in differentiating between children with DLD who have SD from children with DLD who are average spellers by comparing the two groups to each other, to typically developing children as well as children with SD but without spoken language deficits. One hundred forty-nine children, aged 10.40 to 14.00 years, participated in the study. The results indicated that the SD, DLD, and DLD/SD groups did not differ from each other on PA and RAN Letters and underperformed in comparison to the control groups. However, whereas the children with written language deficits (SD and DLD/SD groups) underperformed on RAN Objects and Digits, PWR, OA, and MA, the children with DLD and no SD performed similarly to the children from the control groups on these measures. In contrast, the two groups with spoken language deficits (DLD and DLD/SD) underperformed on RAN Colors in comparison to the control groups and the group of children with SD only. The results support the notion that those children with DLD who have unimpaired PWR and RAN skills are able to overcome their weaknesses in spoken language and PA and acquire basic literacy on a par with their age peers with typical language. We also argue that our findings support a multifactorial model of DLD. 相似文献

We explore the antecedents of corporate spin-offs for a sample of 3462 Spanish firms between 1992 and 2002. Using a resource-based approach, we identify three reasons firms engage in spin-offs: (a) to create complementarities, (b) to appropriate residual rents, and (c) to focus on the core business. Specifically, we find that spin-offs are more common among firms that belong to a group able to create networks and new knowledge that can be exploited through spin-offs. In addition, we find that spin-offs are more frequent in firms that wish to exploit strategic advantages achieved through knowledge investments and in firms that increase efforts to the focus on the parent firm's core competences. 相似文献

The aim of the present study was to investigate the acute effect of the aerobic exercise volume on maximum strength and strength-endurance performance; and possible causes of strength decrements (i.e. central and peripheral fatigue). Twenty-one moderately trained men were submitted to a maximal incremental test to determine anaerobic threshold (AnT) and maximum dynamic strength (1RM) and strength-endurance (i.e. total volume load [TV]) tests to determine their baseline strength performance. Following, subjects performed six experimental sessions: aerobic exercise sessions (continuous running at 90% AnT) with different volumes (3?km, 5?km or 7?km) followed by 1RM or strength-endurance test in the 45° leg press exercise. Maximum voluntary isometric contraction (MVIC), voluntary activation (VA) level, contractile properties, and electromyographic activity (root mean square [RMS]) of the knee extensor muscles were assessed before and after aerobic exercises and after strength tests. TV was lower after 5?km and 7?km runs than in the control condition (12% and 22%, respectively). Additionally, TV was lower after 7?km than 3?km (14%) and 5?km (12%) runs. MVIC, VA, RMS, and contractile properties were reduced after all aerobic exercise volumes (～8%, ～5%, ～11% and ～6–14%, respectively). Additionally, MVIC, VA, and contractile properties were lower after strength tests (～15%, ～6%, ～9–26%, respectively). In conclusion, strength-endurance performance is impaired when performed after aerobic exercise and the magnitude of this interference is dependent on the aerobic exercise volume; and peripheral and central fatigue indices could not explain the different TV observed. 相似文献

Lower limb isometric strength is a key parameter to monitor the training process or recognise muscle weakness and injury risk. However, valid and reliable methods to evaluate it often require high-cost tools. The aim of this study was to analyse the concurrent validity and reliability of a low-cost digital dynamometer for measuring isometric strength in lower limb. Eleven physically active and healthy participants performed maximal isometric strength for: flexion and extension of ankle, flexion and extension of knee, flexion, extension, adduction, abduction, internal and external rotation of hip. Data obtained by the digital dynamometer were compared with the isokinetic dynamometer to examine its concurrent validity. Data obtained by the digital dynamometer from 2 different evaluators and 2 different sessions were compared to examine its inter-rater and intra-rater reliability. Intra-class correlation (ICC) for validity was excellent in every movement (ICC > 0.9). Intra and inter-tester reliability was excellent for all the movements assessed (ICC > 0.75). The low-cost digital dynamometer demonstrated strong concurrent validity and excellent intra and inter-tester reliability for assessing isometric strength in the main lower limb movements. 相似文献

This work describes the genesis, articulation and consolidation from 2007 of a social network of b-learning （blended learning） in the UA （University of Alicante） （Spain）, with the institutional backing of the Office of the Vice President for Education Technology and Innovation, and the momentum and advice of professor Angel Fidalgo （UNESCO （United Nations Educational, Scientific and Cultural Organization） chair for University of Management and Policy）. The social network currently has more than 25 teachers, working on different work linkages with the university, implementing or intending to apply the teaching methodologyb-learning during the course 2007-2008 in a variety of courses and degrees. To do so, several resource centers （blogs, wikis, Wimba Create （before CourseGenie）, etc.）, and digital platforms （Virtual Campus of the UA, Moodle, etc.） are used. 相似文献

Mexican immigrant farm-worker mothers’ class, race, citizenship status, and jurisdictional status of their town in a Northern California community rendered them invisible. However, when the school board decided to close the elementary school the mothers mobilized. Drawing on these mothers’ fototestimonios we examine how they, as cultural citizens, resisted local practices of educational inequity. They wanted to ensure an education for their children. The fototestimonios reveal how farm-worker mothers: (1) negotiated as a collective with the school board; (2) sought negotiation and schooling alternatives; and (3) expressed cultural citizenship through collective efforts to be included within the US polity. 相似文献
