单双音节动词的词频、同素与同义关联研究

基于国家语言资源监测语料库5年高频高稳态词表,采用计量研究的方法,分析单双音节动词对在词频、同素与同义关联上的特点：词频上,单音节动词仅在最高频的小范围区域内占数量优势,单双音节动词在高频词范围内的分布,其比值与词频正相关;词形和词义上,高频的单双音节动词同素与同义关联现象突出且均有高频效应,词频越高的单音节动词同素关联与同义关联能力越强。文章通过穷尽性考察,归纳了高频单音节动词的同素关联能力等级表和同义关联能力等级表,将为汉语的动词分类教学提供数据。     

Beyond the Blockbuster: Good Exhibitions in Small Packages

Many American and European art museums are now featuring small, highly-focused shows in their exhibition programs. In 1990, the Indianapolis Museum of Art organized an exhibition that reunited, for the first time in a century, the four landscape paintings created by neo-impressionist Georges Seurat during the last summer of his life. Using Seurat at Gravelines: The Last Landscapes as an example, this article addresses the advantages — for museums and their visitors — of the small temporary exhibition.     

The assessment of at-risk infants and toddlers with the Bayley Mental Scale and the Battelle Developmental Inventory: Beyond the data

The purpose of this study was to compare the usefulness of the Bayley Scales of Infant Development (BSID)-Mental Scales and the Battelle Developmental Inventory (BDI) in assessing the abilities of infants and toddlers from teen-parent families. The 34 children lived with their mothers, who ranged in age from 15 to 21. The results of the study indicate that these two developmental instruments cannot be used interchangeably and that one needs to look beyond the psychometric data in order to understand the results of infant and toddler assessment. The correlation between the BSID-Mental Development Index (MDI) and BDI Total score was −.03.     

Age,aging and mega-serials in Tamil Nadu

This qualitative, exploratory study examines issues of age and aging surrounding mega-serial (daily soap opera) production in Tamil Nadu, India. This study is timely for demographic reasons (a rapidly aging Indian population) and for the centrality of mega-serials to India’s entertainment landscape, coupled with the genre’s long history of engaging global audiences with real-world social issues. Two data sources are utilized: focus groups with 16 mega-serial viewers and interviews with 25 members of the Tamil mega-serial industry. Situated in scholarship on gerontology/age studies and media/culture industry studies, analysis yields two broad themes related to (a) representations of age/aging and elder-oriented storylines in contemporary Tamil mega-serials and (b) recent industry changes that may forestall mega-serials’ potential to center age and aging as core narrative elements. Overall, evidence points to an industry and audience(s) in considerable transition.     

Injectable hybrid inorganic nanoscaffold as rapid stem cell assembly template for cartilage repair

Cartilage injuries are often devastating and most cannot be cured because of the intrinsically low regenerative capacity of cartilage tissues. Although stem-cell therapy has shown enormous potential for cartilage repair, the therapeutic outcome has been restricted by low survival rates and poor chondrocyte differentiation in vivo. Here, we report an injectable hybrid inorganic (IHI) nanoscaffold that facilitates fast assembly, enhances survival and regulates chondrogenic differentiation of stem cells. IHI nanoscaffolds that strongly bind to extracellular matrix (ECM) proteins assemble stem cells through synergistic 3D cell–cell and cell–matrix interactions, creating a favorable physical microenvironment for stem-cell survival and differentiation in vitro and in vivo. Additionally, chondrogenic factors can be loaded into nanoscaffolds with a high capacity, which allows deep, homogenous drug delivery into assembled 3D stem-cell-derived tissues for effective control over the soluble microenvironment of stem cells. The developed IHI nanoscaffolds that assemble with stem cells are injectable. They also scavenge reactive oxygen species and timely biodegrade for proper integration into injured cartilage tissues. Implantation of stem-cell-assembled IHI nanoscaffolds into injured cartilage results in accelerated tissue regeneration and functional recovery. By establishing our IHI nanoscaffold-templated 3D stem-cell assembly method, we provide a promising approach to better overcoming the inhibitory microenvironment associated with cartilage injuries and to advance current stem-cell-based tissue engineering.
