对手机媒体的传播学思考

手机媒体是一种继报纸、广播、电视、网络四大媒体之后出现的、以手机为载体的媒体,手机媒体传播的特点是即时的大众传播和人际传播的结合,我们可以称之为"人际大众传播"。本文认为,作为"跨媒体"时代信息传播的重要成员,手机媒体对大众传播的广泛参与,优化了传播过程,弥补了以往大众传播的缺陷,同时也打破了主流媒体原有的传播思路与格局,对主流媒体产生了极大的影响。     

Blood,Sweat, and Tears: Navigating Creepy versus Cool in Wearable Biotech

ABSTRACT

This paper considers how personal data protections figure into the design process of wearable technology. The data question is becoming especially important in the face of recent innovations in biotechnology that capitalize on the new fungibility of biology and electronics, in which new biotech wearables capitalize on the ability to analyze and track changes in blood, sweat, and tears. Interviews and participant observation with wearable tech designers, data scientists, fashion tech entrepreneurs, and select experts in cybersecurity and intellectual property law, reveal a range of approaches to data protection in design within the culture where wearables are beginning to merge with biotech. While a few respondents were extremely vigilant about protecting consumer’s privacy, the majority felt that when consumers ‘opt in’ to data sharing, they should be cognizant of the risks. From their perspective, it is not necessarily the producer’s responsibility to protect user's personal data. These attitudes present a problematic logic, which leaves users vulnerable to data exploitation. The paper concludes by arguing that this laissez-faire culture is the environment in which wearable biotech is being developed and will be deployed. This emerging technology raises issues about bodies, data, and ownership in crucial need of analysis and critique to push its move into the mainstream toward more equitable and inclusive ends.     

手机文化传播机制形成路径及其形式

手机被称为“带着体温的媒体”。从朋友、同事、家人之间的人际传播,到单位、地区、国家的群体传播及全球传播,以手机为主的移动互联网正式进入了主流媒体序列,重构了各种文化、社会、政治体系内外媒介传播的权力关系。手机媒体技术与传播形态主要体现在媒介形态创新和使用形式创新两个方面,手机文化传播方式的不断创新与普及,很大程度上改变了人类的思维方式、社交方式和消费方式,带来了文化传播的丰富和繁荣。充分的用户基础、快速的技术创新、网络的安全治理、全媒体的深度融合将使手机发展成为最具竞争力、最有传播效果的主流文化媒体。     

专利司法诉讼对手机产业的影响

自2010年起,全球开始大量涌现有关智能手机或无线技术的诉讼案。在经历了40多起诉讼案后,有关智能手机专利的诉讼至今丝毫没有停止的迹象,甚至愈演愈烈。国内手机企业想要打破发展瓶颈,走向海外、进入高端市场,在未来的竞争中遭遇专利诉讼的挑战是家常便饭。对重庆11家具有代表性的手机企业进行调研可以发现：相比广东等沿海地区的手机企业,重庆本土企业起步较晚,大多处于产业链中下游,核心专利保有量不足。要发展本土企业,提高本土企业的市场竞争力,就必须实行“行政管理部门、立法机构、企业”三者联动机制。政府要有所作为,加大政策、资金、税收等方面的引导和扶持。立法上可借鉴美国的做法,为企业发展保驾护航。企业要加强知识产权管理和重视知识产权战略运用。     

移动应用安全监管中的合谋博弈分析与建议

移动应用安全状况日益凸显,亟需采取相应的监管策略.基于完全信息三方静态博弈模型,探讨移动应用安全监管中政府、移动应用商店以及移动应用开发商三者之间的博弈决策问题.政府通过对应用商店的监管发现存在应用商店与开发商合谋的情况.对于减少应用商店与开发商合谋,政府可给予应用商店未来的合作机会等间接激励,其作用优于现金支持的直接激励.而有效控制监管成本,增加应用商店和开发商合谋所产生的损失,是减少应用商店与开发商合谋概率的有效途径.从博弈角度出发,提出了政府从移动应用传播渠道入手的安全监管策略,即政府在何种条件下能更好发挥通过应用商店间接监管的作用.     

移动舆论场:高校宣传思想工作的新场域

作为意识形态领域的新兴角力场,移动舆论场在改变高校师生生活方式和价值取向的同时,也对新时期高校宣传思想工作提出了新的挑战.要占领意识形态高地,高校必须科学认识移动舆论场的内涵,积极研究和判断形势,利用好移动舆论场的情境创设、具象传播、动态调节、隐性型塑、社交渗透等方面优势,通过思维转变、话语转型和载体融合,切实增强高校宣传思想工作的有效性.     

Information society and digital divide in South Africa: results of longitudinal surveys

Integration into the information society implies that information plays an increasingly important role in all sectors of society and holds distinct social and economic benefits. Discourses on the information society are, however, also associated with the digital divide and inequalities in access to and use of information and communication technologies (ICTs). Within sub-Saharan Africa, South Africa is often regarded as one of the most information-integrated societies due to widespread mobile phone ownership, among other things. However, while ICT access has been emphasized, research also points to the role of demographic, socio-economic and cultural factors such as ethnicity, income, education and gender. This article discusses the results of questionnaire surveys conducted by Afrobarometer among probability South African samples in 2008 and 2011. The results indicate that individual Internet use and mobile Internet access were lower than estimated in the literature. Furthermore, gender gaps, as well as considerable gaps between population groups and educational levels, were found in Internet and computer use, mobile ownership and access to mobile Internet and accessing news via the Internet. Conclusions regarding strategies for bridging the digital divide and integrating South Africa into the information society are discussed.
