语言价值、权力结构与国际组织的语言选择

国际组织的语言选择是其行政机构及成员基于组织特性、语言价值等多种考量因素进行博弈的结果。为实现国际组织的宗旨和目标，其行政机构基于国际组织的“组织性”特征尤为注重语言的实用价值，甚至以此作为主导性考量因素，英语因而在国际组织的语言选择中占据主导地位。然而，“国际性”特征要求国际组织必须兼顾语言的象征价值，这与其成员彰显本国语言的诉求相吻合。国际组织成员尤其是成员国的权力强弱对国际组织的语言选择影响深远，部分成员通过在特定国际组织中推广本国语言的使用来提高自身的国际地位及影响力。同时，历史因素通过保留国际组织权力结构中的正式制度对其语言选择产生延迟性影响，致使语言政策的变革滞后于成员之间的相对权力动态。     

科技创新、产业复杂度与经济增长

科技创新能够通过产业复杂度的变化对经济增长产生影响.以1995—2019年世界银行和哈佛大学Atlas数据库的科技创新为研究样本,运用中介效应检验方法,考察科技创新如何通过纺织类、农业类、钻石类、矿产类、金属类、化工类、汽车类、设备类和电子类的产业复杂度变化来影响国民生产总值,从而揭示了科技创新如何通过产业复杂度的变化影响经济增长的机理.研究结果表明:从总体上看,科技创新影响经济增长的过程中,产业复杂度的中介效应量为90.83％,具有显著性,其中农业类、钻石类以及矿产类相关系数为负,其他类别相关系数为正,电子类作用程度最高.区分经济体类型的研究结果显示:产业复杂度的中介效应存在异质性,发达经济体、亚洲经济体、技术密集型经济体存在相对优势,而且科技创新促进经济增长开启了"机会窗口期",后发经济体可以实现"弯道超车".这一研究结论有助于丰富科技创新领域的相关成果,能够为引导产业转型升级方向、提高国家经济增长能力提供理论依据和经验借鉴.     

Abusive Supervision and Well-Being of Filipino Migrant Workers in Macau: Consequences for Self-Esteem and Heritage Culture Detachment

Abusive supervision in the workplace has been shown to have important direct consequence in work and work relationship, and also indirect consequences to workers’ well-being and relationships outside work. Consequences of abusive supervision have not been studied among migrant workers whose status in the host country of work is dependent on maintaining the work contract. This study investigates abusive supervision in 247 Filipino migrant workers in Macau, who hold temporary work contracts and work visas to engage in various low-skilled work (e.g., domestic helper, security guard, etc.). The study tests a model representing the indirect consequences of abusive supervision on the self-esteem and acculturation orientation of migrant workers, in particular, on the tendency to reject their heritage culture in their attempt to acculturate in the host country. Mediation analysis indicated that abusive supervisory perceptions led to lower self-esteem (b = ?.19), which in turn relates to tendency to reject their heritage culture as part of acculturation (b = ?.45) [indirect effect = .08, 90 % CI .04, .15]. The rejection of heritage culture is interpreted as a coping response to the negative indirect consequences of abusive supervision perceptions that may be partly attributed to being a migrant Filipino worker. The results are discussed in terms of how the acculturation of migrant workers reflects aspects of their well-being that may be adversely affected by vocational-related stress in the host country.     

磷酸酯/Fe3+ 型油基冻胶压裂液性能研究

针对磷酸酯/Al3+ 交联的油基压裂液交联速度慢，交联剂溶解性慢、稳定性差和价格高等缺点，首次对磷酸酯/Fe3+ 交联的油基压裂液体系进行了研究。通过对铁交联剂体系的优化，筛选一种磷酸酯/Fe3+ 交联的新型交联剂体系，并对磷酸酯/Fe3+ 油基冻胶压裂液性能进行了评价。结果表明：采用30%Fe2(SO4)3+15% 二乙醇胺+55% 水制备的新型交联剂体系，直接与磷酸酯混合即可形成油基冻胶，其性能不受放置时间的影响，交联速度快，成胶性能好，10 min 就可达到最大黏度；压裂液的抗温抗剪切性能高，与常规铝交联剂体系比较，压裂液成胶速度提高了20 倍，压裂液的抗温能力由原来100 ℃提高到135 ℃，并且压裂液的破胶性和滤失性等性能均能达到压裂施工的要求。     

我国地方食品安全监管体系研究——以江苏省为例

食品安全一直是每个国民心中的"中国梦"。随着政府机构改革对食品安全问题的日益重视,新的监管体系正在形成。而地方政府作为国家食品安全监管的具体执行者,其所处的地位、所承担的责任、所拥有的权限决定了它是整个监管工作的关键。本文通过对江苏省食品安全监管体系的研究,尝试提出解决食品安全监管问题的建议。     

庄子孝道研究

庄子敏锐地观察到世俗孝道存在着虚伪性及其标准的不确定性,他认为这是人们的成见即人为的结果。他反对这种人为的世俗孝道,提倡一种不带任何成见的至真至诚的孝道观。庄子的孝道的道德境界分为"敬""爱""忘亲""使亲忘我""兼忘天下""使天下兼忘我"六种境界。他认为这种孝道观的道德境界高于以儒家为代表的世俗的孝道观,并且最终与"道"、"德"相合。     

Feminist and empowerment theory and social work practice

Feminist and empowerment theories are especially important to the understanding of individual and sociopolitical levels of social work assessment and intervention. Incorporating feminist and empowerment approaches in practice will provide social workers with the knowledge, values and skills most likely to promote human rights and social justice. In this paper, we present an overview of both theories and illustrate them with a case example.
