WSN based intelligent cold chain management

This paper presents a cold chain monitoring system which is implemented by using ubiquitous computing technologies, Radio Frequency Identification (RFID) & Wireless Sensor Network (WSN). In this paper, we discuss how cold supply chain works and how we can monitor and control cold supply chain by using wireless tracking and sensing technologies. We propose a prototype design which will provide a well controlled and transparent cold chain system, which could help the users to manage their products’ environmental data in real time during the life cycle. Moreover, we highlight how the availability of product trace data in combination with historical condition-monitoring data can facilitate decision-making processes enhancing supply chain’s performance. Finally we discuss the integration works of these two technologies together in the cold supply chain management system. Hardware and software platform of WSN used in this system are also described in this paper

Networked collective action in the 2014 Hong Kong Occupy Movement: analysing a Facebook sharing network

Using a “big data” approach, this study aims to demonstrate and analyse the way in which the formation of an online network, i.e. posts sharing between Facebook pages, help construct a countervailing power during the course of the Hong Kong Occupy Movement (or called “Umbrella Movement”), which protested against the electoral reform framework imposed by the Standing Committee, China’s National People’s Congress in relation to the implementation of universal suffrage for the 2017 Hong Kong Chief Executive election. The result indicates an empowerment of emerging civil society in the venue of policy debate, whereas there was a disintegration between institutional political forces and the civil society. This may not be conductive to an institutionalized policy formation involving a variety of stakeholders amid the controversy.postprin
