Understanding information propagation on online social tagging systems: a case study on Flickr

Online social networking services (SNS) have been regarded as one of the most powerful online communication channels to propagate information to other users. It means that the online social networking services are providing users with efficient features (e.g., searching, managing and visualizing new information). It is important for many online collaborative applications to understand how the information can be propagated via such social media. Thus, we want to focus on a social tagging system (e.g., Flickr) where users can easily exchange resources as well as their tags. In this paper, given a certain tag, a social pulse can be established by counting (i) the number of users and (ii) the number of resources over time. More importantly, we assume that information can be propagated by (iii) inducibility from other tags by comparing social pulses. To conduct experimentation, a tag-based searching system (called Tagoole) has been implemented to collect a dataset from Flickr.     

张力控制系统在变频造纸设备中的应用研究

张力控制在变频造纸设备中的应用是造纸业的控制难题。本文构建了变频造纸设备张力控制系统模型,通过张力检测装置采集张力值,经PLC接收和判定,最终组成了直接张力控制系统,有效地保证了张力的恒定。同时采用Simulink工具箱,模拟和分析了Matlab软件环境下张力控制系统的仿真运行,最终证实了张力控制系统在变频造纸设备应用中的可行性,为张力控制系统的后续研究与发展指明了方向。

Chaebol,Unions, and the Profitability of Korean Firms Before and After the Crisis

Before the 1997 crisis, Korean firms destroyed shareholder value and chronically produced nonperforming loans for financial institutions. In particular, chaebol‐affiliated and unionized firms did so, with lower profitability among the financially unsound firms. Chaebol and unions thus functioned as institutional devices whereby managers and workers undermined the interest of taxpayers as well as shareholders. After the crisis, firms no longer destroy shareholder value or produce nonperforming loans. Chaebol‐affiliated and unionized firms have higher profitability among the financially unsound firms. Chaebol and unions have thus ceased to function as institutional devices whereby managers and workers undermine the interest of shareholders and taxpayers.
