多层微波集成电路中微带线层间互连仿真

针对多层微波集成电路设计的微带线层间互连问题，介绍了垂直通孔互连、垂直带条互连和层耦合过渡互连三种高性能的互连方法，并且采用三维电磁仿真软件HFSS对这三种互连结构进行了建模和仿真。仿真结果表明，垂直通孔互连和垂直带条互连在0.1～25 GHz的频宽范围内，回波损耗S11<-20 dB，插入损耗S21>-1 dB，互连性能优良，而层耦合过渡互连在20～68 GHz内回波损耗S11 <-20 dB，插入损耗S21>-1 dB，具有在毫米波频段实现互连的潜力。

Determinants of materiality disclosure quality in integrated reporting: Empirical evidence from an international setting

This study examines determinants of materiality disclosure quality (MDQ) in integrated reporting (IR) in an international setting. To this purpose, we constructed a novel, hand‐collected MDQ score in line with the <IR> guiding principles introduced by the International Integrated Reporting Council. On the basis of a cross‐national sample consisting of 359 firm‐year observations between 2013 and 2016, we find that MDQ is positively associated with learning effects, gender diversity, and the assurance of nonfinancial information in the integrated report. On the other hand, we find that IR readability, listing in the Dow Jones Sustainability Index, and earnings management do not affect MDQ. Our results are robust to different statistical models. We expand on earlier empirical findings on IR disclosure quality and provide valuable insights for research, practice, and standard setting.     

汽车类院校一体化教师培养模式的研究

随着我国社会主义市场经济和职业教育的迅速发展,社会及企业要求学校毕业生要有一定的理论知识又要有很强的实际操作能力。新的人才需求要求有新的教学模式——"专业基础理论与技能实践一体化"教学模式,要成功地实施一体化教学模式,建设一支既能胜任理论教学又能指导实习操作的"双师型"教师队伍是实施一体化教学的关键。本文就汽车类院校一体化教师培养模式进行探索。     

党建工作与国有企业文化相融建设刍议

国有企业文化是国企各部门之间协作的粘合剂,是国企蓬勃发展的重要基石,也是国企的立身之本。党建工作对于国企而言可以为其发展指明方向,提供思想保障,能够让企业发展更为坚实。党建工作与国有企业文化相融建设能够让企业的结构更为完整,企业的内核更为充实,企业的发展也能够更为顺利高速。论文分析了党建工作和国有企业文化之间的关系,为二者的融合打好基础,有效提升国企软实力,推动我国经济的进一步发展。     

Linking sustainable business models and supply chains — Toward an integrated value creation framework

Extant literature on sustainable business models highlights that value creation stems from resources exchanged in relationships between a focal firm and its stakeholders. In this context, the literature has, so far, focused on direct relationships. However, despite the acknowledged relevance of sustainability issues in supply chains, this relational view of the focal company and its direct stakeholders has not been extended toward value creation for and with indirect stakeholders, such as stakeholders of suppliers. Addressing this gap, this conceptual article integrates a relational view of sustainable supply chain management into the management of sustainable business models. It extends the scope of sustainable business models from relationships between the focal firm and its direct stakeholders to indirect relationships with stakeholders of suppliers. A framework is developed that supports analysis and management of value-creating relationships between the focal firm, suppliers, and stakeholders of suppliers. By extending the conceptualization of sustainable business models to consider relationship chains beyond direct relationships, this article proposes that a focal firm has to actively manage interactions both with suppliers and with suppliers' stakeholders.     

The development of integrated marketing communications at the British General Post Office, 1931–39

In the 1930s, the General Post Office (GPO) in Britain became one of the nation’s most innovative pioneers of marketing communication. Following criticism of the organisation in the 1920s for its conservative use of publicity, the GPO embarked upon a series of creative publicity campaigns that applied, amongst other methods, advertising, public relations, promotions, cinema, events and artistic posters. Through an overview of its publicity, and through a narrative of three case-studies, this article argues that one of the most important innovations of the GPO was its integration of marketing communication, both in terms of techniques used and in relation to its emphasis in promoting the organisation and the services it provided.     

Short-term forecasting of Japanese tourist inflow to South Korea using Google trends data

We utilize the Internet search data from Google Trends to provide short-term forecasts for the inflow of Japanese tourists to South Korea. We construct the Google variable in a systematic way by combining keywords to minimize mean squared or mean absolute forecasting errors. We augment the Google variable to the standard time-series forecasting models and compare their forecasting accuracies. We find that Google-augmented models perform much better than the standard time-series models in terms of short-term forecasting accuracy. In particular, Google models show better out-of-sample forecasting performance than in-sample forecasting.
