Sense of belonging,international migrants’ spending,and implications for their subjective well-being

A lack of a sense of belonging in the host country has become one of the most common challenges facing international migrants in today's sociopolitical environment. Our two online experiments with 881 international migrant workers in the United States jointly demonstrate that, to cope with their lack of a sense of belonging in the host country, international migrants may spend money suboptimally: more on material purchases but less on experiential and prosocial purchases. More importantly, our studies suggest that prosocial purchases are more effective than experiential purchases in increasing international migrants’ subjective well-being. This is because prosocial purchases can lead to both relatedness need satisfaction and beneficence, with each independently contributing to international migrants’ subjective well-being. Our research suggests that public policymakers should address the social exclusion international migrants experience when moving to a new country because it can have a negative impact on their subjective well-being. Our research further suggests that one way to mitigate social exclusion is to encourage international migrants to spend money on others rather than themselves.     

一种基于数据挖掘的面条品质综合评价方法

为了准确评价面条品质,文章以46种不同品牌的市售面条为材料,通过实验采集面条样本的力学性能数据和其他属性数据,对构建的数据集进行主成分分析,并借助其结果进行聚类分析,样本最终被划分成5个类,对面条样本进行感官评价。参考感官评价的指标再对每一个簇中的样本进行评价,描述出每个簇中面条样本的品质特性。该方法融合了多种数据分析和评价方法,既具备数据分析的客观性,又不失主观评价的优势。     

浅谈如何实现健康老龄化

我国老年人口占全球老年人口总量的1/5,解决这样庞大的老年人问题,必将在全球产生深远的影响。联合国明确提出,将健康老龄化作为全球解决老龄问题的奋斗目标。老有所乐是实现健康老龄化的精神保障,要创造温馨氛围、发展老年教育、实现老人价值、开辟消费市场等让老人快乐。老有所养是实现健康老龄化的物质基础,这就牵涉到养老金、谁来养和怎么养等系列问题。     

起落航线训练目视飞行下跑道容量评估

对混合运输的机场来说,运输飞行的效率与起落航线上的飞行训练的效率是互相影响的。为了做出此类型下的跑道容量评估,提出考虑起落航线训练目视飞行下的跑道容量评估模型。该模型考虑了训练飞行目视间隔对起飞间隔的影响,抽象航空器占用跑道时的运行过程,以目视间隔为关键因素,在此基础上分析讨论运输类型以及机型对跑道容量的影响。使用Anylogic进行仿真计算,结果表明使用目视间隔可以大幅提升跑道服务能力,容量提升了55%左右,验证了该方法和模型的有效性。     

一种基于虚拟现实技术的植物景观规划设计方案评价与修正方法——以长荡湖旅游度假区为例

为能够定量评估、优化植物景观规划设计方案,基于虚拟现实技术,改进传统的BIB-LCJ法和SD法,采用主成分分析和回归分析筛选出植物群落丰富度、色彩对比度、季相特征、植物配置模式、植被多样性和林冠线变化6项显著视觉特征要素,形成一种基于虚拟现实三维建模技术的植物景观规划设计方案评价与修正方法。并以长荡湖旅游度假区植物景观规划设计方案为例,对方案视觉质量进行评价,实验过程证明了研究方法的可靠性。

住房差异与居民社会公平感——基于社会阶层视角

依据2017年中国综合社会调查数据,运用有序概率模型,考量住房差异对居民社会公平感的影响及作用机理。结果显示：较少住房面积和无住房产权负向影响居民社会公平感;较多住房面积和拥有住房产权正向影响居民社会公平感;一套住房产权比多套住房产权更能促进居民社会公平感的提升。社会阶层认同和社会阶层预期在较少住房面积和无住房产权群体中表现出正向调节作用;在较多住房面积和拥有住房产权群体中表现出中介作用。住房差异在社会阶层上向流动时正向影响居民社会公平感。鉴于此,应保障住房权利,强化社会阶层预期,提高居民社会公平感。     

Using Social Influence Processes and Psychological Factors to Measure Pervasive Adoption of Social Networking Sites: Evidence from Pakistan

Social networking sites (SNS) have emerged as a popular and convenient tool for connecting with different groups of people on a specific platform. This study examines the effect of social influence processes and psychological factors on the behavior of students’ pervasive adoption of SNS. Data were collected through a survey questionnaire. Partial least square was used for data analysis. Findings reveal that privacy, identification, and internalization ensure significant association with the intention to use SNS, ultimately has a positive effect on the pervasive adoption of SNS and so does gender. However, men were found to be less aware of privacy issues.
