假日旅游消费存在的问题及对策

假日旅游以黄金周为单位、采取集中休假的方式拉动了消费,在改变人们休闲观念的同时,也给交通、旅游部门带来了巨大压力,并造成长假前后出现消费萧条等问题。因此,应加强旅游景点的建设与创新,注重差异化的旅游商品开发。此外,政府与社会应相互配合、共同管理,正确引导假日旅游消费。     

试析语感研究的现状及存在的问题

从语感研究的现状看,关涉语感本身的理论问题得到了比较深入的研究,也取得了很多成果。同时,语感作为我国第八次课程改革《语文课程标准》的核心词汇之一,语感培养问题开始真正走进人们的思维视阈。由于现实上语感实践环节的研究相对薄弱,从而造成语感教学实践成为目前语感研究面临的最大问题,其中既包括语感教学实施也包括切合实际的语感评价指标体系建立。     

新形势下高校"双培"工作面临的突出问题与对策

高校"双培"工作即把高校高知识群体中的优秀分子培养成为党员,把其中优秀党员培养成为党组织负责人,做好该项工作具有重要的历史和现实意义.由于对"双培"工作的重视不够,高校的"双培"工作普遍遇到了一些新的突出问题.新时期做好高校的"双培"工作,必须切实提高高校"双培"工作的针对性、实效性和长效性.     

湖南省区域中心城市发展中的人口问题研究——以长株潭城市群为例

基于长株潭城市群人口发展现状,利用相关人口指标与武汉、广州等经济发达城市相比较,表明长株潭城市群在人口规模、行业人口结构及人口质量等方面存在一些问题,并提出促进城市发展的人口对策。     

心身问题的问题式

笛卡尔时期奠定了心身问题的古典结构,即心身问题的两个基本面、解答的基本思路及困境。现代心灵哲学(特别是英美传统)之思维方式有了一些新特点,即不愿接受无逻辑负担的直觉、不会直接引入上帝超自然力的干预、自上而下的思辨式的形而上方法深深受到怀疑。现代哲学在研究心身问题时引入了三个新的视角,即指称问题、语言问题和还原问题,进而细化了心身问题的古典结构。心身问题奠基于笛卡尔开始的主客二分的祛魅的现代性世界观,自由意志问题是能否跳出心身问题之困境的试金石,而心身问题又是我们能否跳出现代性图景的试金石。     

21世纪世界人口面临的主要问题与挑战

人类跨入 2 1世纪 ,在迅速发展经济的同时 ,也面临着一些问题和挑战。世界人口数量急剧增长 ,人口倍增时间大为缩短。人口老化速度加快 ,在 2 1世纪的前 10年 ,世界各国都将出现人口老龄化趋势。随着现代化工业和市场经济的飞速发展 ,全球人口城市化速度日益加剧。同时贫困人口问题困扰发展中国家。人类为了满足自身发展的需要 ,导致自身资源日益减少 ,生态环境日益恶化 ,如不设法采取补救措施 ,将会面临一场生态灾难     

对广东省流动人口婚育问题的初探

:广东是我国流动人口最多的省份,流动人口的婚育问题也成为研究的热点之一。本文首先对流动人口作了界定,并分析了广东流动人口的特征及其对婚育行为产生的正面和负面影响,这使计划生育管理面临巨大的压力。文章最后提出一些措施以图化解流动人口的婚育问题带给城市的压力     

Crisis perceptions,relationship, and communicative behaviors of employees: Internal public segmentation approach

This study examines when and why employees engage in external communicative behaviors during the periods of a corporate crisis. Combining a cross-situational factor (i.e., pre-crisis relationship quality) and a situational factor (i.e., crisis-specific perceptions), this study segments internal publics to understand employees’ motivations of becoming advocates for or adversaries of their organization. The results of an online survey demonstrated that employees’ pre-crisis relationship to their organization plays a critical role in encouraging them to advocate for their company; meanwhile, their crisis-perception—whether they feel fewer constraints in solving a crisis—is more likely to make them share negative information externally. Segmented groups of employees with high levels of both relationship and activeness are most likely to engage in both positive and negative external communication behaviors. Theoretical and practical implications for public relations and internal crisis communication are suggested.     

基于随机p-鲁棒优化的国家血液战略储备库选址-库存模型

以往的救灾实践对建立国家血液战略储备体系提出了迫切要求。国家血液战略储备库的建设问题亟待解决。由于血液产品特性以及应急血液保障特性的存在,使得国家血液战略储备库的选址决策具有一定的复杂性。本文将问题定位为选址-库存问题。首先,以应急条件下血液保障及时度最高为目标,构建了一个不确定环境下考虑多情景、多血型、多阶段、带提前期、有容量限制、日常随机需求、有预算约束及协同定位的国家血液战略储备库选址-库存模型。同时,为了规避应急条件下的不确定风险,进一步构建了国家血液战略储备库选址-库存问题的随机p-鲁棒优化模型。该模型为离散非线性混合整数规划模型,难以快速精确求解。故基于模型性质,设计了相应的遗传算法。最后,设计了两组算例验证模型与算法的有效性。其中,第1组算例基于我国大陆地区31个省级血液中心与省级行政区的数据,并根据不同预算值给出6个算例,得到了国家血液战略储备库的选址-库存决策方案。第2组算例为6个不同规模的模拟算例,用来测试不同规模下的算法性能。算例结果表明：遗传算法的性能更好;鲁棒解与确定性模型最优值相差不大（最大差距≤1.08%）,可降低不确定性导致的风险。实践中,可对本文所建模型稍作改进,应用于具有类似特征的易腐品（药品、粮食等）应急物资储备库选址-库存决策。     

Understanding end-user perspectives to enhance perceived value uptake of harm-minimization tools: considering gambler’s views of a pre-commitment system

Harm-minimization strategies reduce the experience of gambling-related harms for individuals and those close to them. Most policies and particularly discussions of tool design and implementation fail to involve end users and consider their concerns and needs. This study aimed to investigate the best way to introduce a harm-minimization tool for electronic gaming machines (EGMs) that will maximize the perceived value and subsequent uptake by the intended audience of gamblers. Focus groups were conducted with 31 Australian regular EGM gamblers experiencing a range of gambling problems. Participants were asked their perspectives of a pre-commitment system (features including accessing activity statements, setting limits, viewing dynamic messages, taking breaks), including concerns, and how to enhance perceived value and usefulness. Positive attitudes about the system were expressed; however, many gamblers saw the tool as relevant only for problem gamblers. Participants indicated that value could be enhanced by making the system flexible and customizable, but still easy to use. Design and implementation strategies such as incorporating flexibility in features, ease of use, appropriate terminology, and educational efforts may address gamblers’ concerns, particularly regarding privacy and potential stigma. This would enhance user perception of harm-minimization tools as relevant and may subsequently enhance effectiveness.
