The Relations Between Early Working Memory Abilities and Later Developing Reading Skills: A Longitudinal Study From Kindergarten to Fifth Grade          下载免费PDF全文

Einat Nevo  Irit Bar‐Kochva 《Mind, Brain, and Education》2015,9(3):154-163

This study investigated the relations of early working‐memory abilities (phonological and visual‐spatial short‐term memory [STM] and complex memory and episodic buffer memory) and later developing reading skills. Sixty Hebrew‐speaking children were followed from kindergarten through Grade 5. Working memory was tested in kindergarten and reading in Grades 1, 2, and 5. All memory measures, but phonological STM, correlated with reading up to Grade 5. Regression analyses (with intelligence quotient controlled) demonstrated that phonological complex memory predicted all reading skills in Grade 1, and accuracy in Grade 2. The rather understudied visual‐spatial memory predicted comprehension in Grades 2 (STM) and 5 (complex memory). The results point to an important role of the phonological complex memory in early assessment, and suggest a long‐lasting role of early visual‐spatial memory in predicting variance in reading. Whether this role of the visual‐spatial memory is unique to the Hebrew orthography because of its visual features requires, however, further investigation.  相似文献   

The citation evolution law of papers published in the same year but different month          下载免费PDF全文

GAI Shuang‐Shuang  LIU Xue‐Li  ZHANG Shi‐Le  LIU Rui‐Yuan 《Learned Publishing》2015,28(2):132-139

To explore the citation evolution of papers published in the same year but different month, we selected papers from a discipline (physical geography), a subject (diabetes: endocrine and metabolism) and a journal (Journal of Biological Chemistry) published in 2005 as research objects. These papers were divided into six groups according to the difference in publication month, and we analyzed citations to these papers for the 9 years after publication. The results showed that within 5 years after papers from physical geography were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); after that, the differences were not statistically significant. Within 5 years after papers from diabetes (endocrine and metabolism) were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Within 7 years after papers from the Journal of Biological Chemistry were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Citations of papers followed the same pattern irrespective of discipline, subject or journal: citations of papers published in the same year but different month were obviously different in the first few publishing years, but as time went on, only the difference in publication month in a calendar year did not affect the papers' longer‐term citation.  相似文献   

Collagen-based brain microvasculature model in vitro using three-dimensional printed template

We present an engineered three-dimensional (3D) in vitro brain microvasculature system embedded within the bulk of a collagen matrix. To create a hydrogel template for the functional brain microvascular structure, we fabricated an array of microchannels made of collagen I using microneedles and a 3D printed frame. By culturing mouse brain endothelial cells (bEnd.3) on the luminal surface of cylindrical collagen microchannels, we reconstructed an array of brain microvasculature in vitro with circular cross-sections. We characterized the barrier function of our brain microvasculature by measuring transendothelial permeability of 40 kDa fluorescein isothiocyanate-dextran (Stoke''s radius of ∼4.5 nm), based on an analytical model. The transendothelial permeability decreased significantly over 3 weeks of culture. We also present the disruption of the barrier function with a hyperosmotic mannitol as well as a subsequent recovery over 4 days. Our brain microvasculature model in vitro, consisting of system-in-hydrogel combined with the widely emerging 3D printing technique, can serve as a useful tool not only for fundamental studies associated with blood-brain barrier in physiological and pathological settings but also for pharmaceutical applications.  相似文献   

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow     

Jeonghun Nam  Justin Kok Soon Tan  Bee Luan Khoo  Bumseok Namgung  Hwa Liang Leo  Chwee Teck Lim  Sangho Kim 《Biomicrofluidics》2015,9(6)

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.  相似文献

Investigating the Development of the “Mobile Museum” from the Perspective of Service     

Chia‐Hui HUang  Fang‐Suey Lin 《Curator: The Museum Journal》2016,59(4):387-410

During economic development, modern museums face competition from various leisure activities and entertainment sites, and to achieve sustainable development, museums should reflect on providing high‐quality service to satisfy visitors’ expectations. Based on service design‐related theories, this research team conducted a case study to explore the planning, implementation, and meaning of Mobile Museums. It investigated design development from the perspective of public service design and summarized the policy, design, and service satisfaction results for Mobile Museums. Finally, the similarities in service processes are discussed between Mobile Museums and the general service industry. According to this study, attracting more visitors is the biggest issue facing museums today, as are the ways in which museums must actively provide service and become recognized to compete with others. This study identifies the onstage and backstage support of museums as well as their cultural features and non‐profit services.  相似文献   

Block Talk: Spatial Language During Block Play     

Katrina Ferrara  Kathy Hirsh‐Pasek  Nora S. Newcombe  Roberta Michnick Golinkoff  Wendy Shallcross Lam 《Mind, Brain, and Education》2011,5(3):143-151

Spatial skills are a central component of intellect and show marked individual differences. There is evidence that variations in the spatial language young children hear, which directs their attention to important aspects of the spatial environment, may be one of the mechanisms that contributes to these differences. To investigate how play affects variations in language, parents and children were assigned to 1 of 3 conditions: free play with blocks, guided play, or play with preassembled structures (Study 1). Parents in the guided play condition produced significantly higher proportions of spatial talk than parents in the other two conditions, and children in the guided play condition produced significantly more spatial talk than those in the free play condition. Study 2 established baselines of spatial language during activities not involving spatial materials. Proportions of spatial words were lower than those in any of the conditions of Experiment 1. In sum, interaction with blocks naturally elicits elevated levels of spatial language, especially in the context of guided play, suggesting simple‐to‐execute educational interventions.  相似文献   

Modifications of Recognition Memory Processes in Preterm Children: An Event‐Related Potential Study          下载免费PDF全文

Prematurity may cause hippocampal compromise. Therefore, hippocampus‐dependent memory processes (recollection‐based retrieval) may be more impaired than hippocampus‐independent processes (familiarity‐based retrieval). The memory of 18 children born preterm with reduced hippocampal volumes, without neonatal complications (weeks of gestation < 34, weight < 1,600 g), and 15 controls (8–10 years) was tested using an item recognition task. While groups were equal in memory performance, dissociation was found: The event‐related potential (ERP) correlate of familiarity was intact in the preterm group, whereas the correlate of recollection was attenuated. A follow‐up experiment ruled out that this was due to general cognitive deficits. Furthermore, gestational age correlated with the ERP index of recollection. Thus, recognition memory in preterm children may be characterized by a compensation of attenuated recollection by familiarity.  相似文献
