不同的地域差异呈现出不同的文化生态,地域文化所具有的独特性将是动漫衍生品在同行业竞争中的优势.本文从整个安徽文化的脉络思考出发,着重深挖提炼安徽传统民间文化中典型的视觉元素,为开发具有安徽地域文化特色、富有创新意识的衍生产品提出思路,使安徽动漫衍生品的开发步入良性循环的发展格局.     

粤港澳大湾区经济中心对粤北地区的经济辐射作用分析——以清远市为例

发挥经济中心对周边地区的经济辐射作用对一个区域的经济协同发展具有重要意义。粤北地区特别是清远市可以说是藏在粤港澳大湾区经济焦点下的盲点。借助地理距离优势,跨越发展鸿沟,使周边地区与粤港澳大湾区实现融合式互动和一体化发展,是一个具有重要研究价值的问题。可以将粤港澳大湾区及其周边地区作为一个城市群,描述和测算其基本发展现状及经济分布格局,探索经济辐射的必要性与可能的辐射路径。     

非稳态雾赋能网络中的在线任务卸载方法

为充分发掘分布在不同位置上的雾节点的计算资源,任务卸载被寄予众望。在雾计算场景下,以尽可能减少任务卸载的长期成本为目标,试图寻找一个高效的在线任务卸载方法。为此,这一问题被建模成一个随机规划问题,该问题中系统参数所对应的随机变量的期望会在未知时刻突变,系统参数相关信息只能在任务完成后的反馈中获得。基于非稳态多臂老虎机模型,提出一个高效的算法来解决这一具有挑战性的随机优化问题,给出理论分析证明该算法的渐进最优性。数值实验证明了该算法的优越性。     

以就业为目标的职业中专教育改革研究

职业中专的教育模式与普通高中不同,以就业为目标培养专业技术人才是决定职业中专教育模式的根本。要实现这一目标,职业中专必须确立实践教学的主体地位,作为教学模式的导向。     

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.

浅析网络舆论暴力成因——以“后妈虐童”事件为例

综观近年来发生的网络舆论暴力事件,尽管大多数网民的出发点是为了弘扬正义、惩奸罚恶,但它对当事人和社会的影响却不可低估,而且网民的表达方式和采取的实际行动是否理性值得探讨,鉴于舆论暴力事件日益增多,本课题旨在通过分析网络舆论暴力现象的特点、表现,运用传播学理论和相关社会学的视角对该现象做根源、理论上的探究.     

俄罗斯退休养老金

养老问题是目前全球性的问题,一方面人口老龄化的压力愈发沉重,另一方面养老成本明显提高,在众多国家面对如此棘手问题的时候,俄罗斯联邦却做得举国上下称赞,很值得我们借鉴。
