论新自由主义对中西传媒业的影响

新自由主义的推行带来的是西方传媒业管制渐进放松,随之出现了前所未有的大兼并、集中、整合的现象和超级跨国传媒公司的产生,多数人看到的只是新自由主义给西方传媒带去的繁荣和快速发展,而很少有人发现新自由主义给西方传媒带去的还有民主的丧失、新闻自由的虚伪、公共利益维护的缺位、公平正义平等理念的歪曲。二十多年来的中国传媒改革在很大程度上也受到了新自由主义思潮的影响,但我们必须明确,中国传媒产业改革应当在批判吸收新自由主义理论的基础上,走出一条中国式的改革之路。     

对我国科技传媒产业集团化的思考

加入WTO后,我国科技传媒业面临着前所未有的挑战。组建集团、整合传媒资源、形成整体优势是我国科技传媒业应对严峻局面的必然选择。在分析了我国科技传媒业现状的基础上,结合当前的实际,提出了我国科技传媒业实行集团化的思想,并对其组建方式以及应注意的问题进行了详细阐述。     

技术与交往的媒介关联及其生态学意义

技术是推动人类交往进步的重要动力。任何新型媒介的出现,都是人类技术选择的结果。在技术浪潮推动下,媒介正在成为不断提升人类传播力、延伸人类交往方式的重要工具。在对前技术环境的改造过程中,人类理性发挥了重要作用,决定了媒介演化的人性化方向,体现着技术价值的最优化规律。因而,在新的传播生态环境的形成过程中,技术具有突出的建构意义,也正在使绿色互联、全球化交往等大生态观念成为重要的人类共识。

The reconstruction of transportation and environmental infrastructure in rural areas

On March 11, 2011 a massive, magnitude 9.0 earthquake destroyed most of the rural areas along the Pacific Coast of eastern Japan, an area that had been facing issues of depopulation and aging even before the earthquake. In this paper I discuss reconstruction plans for depopulated rural areas from the perspectives of transportation infrastructure, residential areas, agriculture, forestry, fisheries, consensus building, and nature restoration. We must take a “backcasting” approach to sustainable development, one in which planning strategies lead to successful outcomes. An organizational and planning support platform is needed to build a consensus within an area.     

Measuring social effective speed to improve sustainable mobility policies in developing countries

Over the last few decades, many developing countries have experienced car fleet growth, which has contributed to congestion, increased travel times, and deteriorated public transport reliability and punctuality. However, alternatives to urban mobility can be found by creating policies to stimulate sustainable transportation modes with equal opportunities for all citizens. In this paper, measures of social effective speeds are presented to improve sustainable urban mobility policies in developing countries. Data from the 2018 Origin-Destination Survey of the Metropolitan Region of Recife (Brazil) were used to estimate social effective speeds. The results showed that motorized modes had lower effective speed than non-motorized modes. In addition, total external costs were $2 billion USD per year. The social effective speed will be valuable if inserted in sustainable urban mobility policies in developing countries.     

Impact of transition between signal timing plans in social cost based in delay,fuel consumption and air emissions

Significant effects of traffic congestion include the cost associated with extra travel time, fuel consumption, and gas emissions. This paper develops a mathematical function to quantify the monetary impact of transition designs between signal timing plans on users and the environment. This function offers an approach to reduce problems such as excessive travel time, pollution emissions and fuel consumption. The proposed social cost function is evaluated for various transition plans to assess the impact of the number of steps required to adjust signal timing. The relationships between delay, fuel consumption and gas emissions and the number of steps needed to achieve the transition are also analysed.     

An empirical investigation into the time-use and activity patterns of dual-earner couples with and without young children

This paper examines the time-use patterns of adults in dual-earner households with and without children as a function of several individual and household socio-demographics and employment characteristics. A disaggregate activity purpose classification including both in-home and out-of-home activity pursuits is used because of the travel demand relevance of out-of-home pursuits, as well as to examine both mobility-related and general time-use related social exclusion and time poverty issues. The study uses the Nested Multiple Discrete Continuous Extreme Value (MDCNEV) model, which recognizes that time-decisions entail the choice of participating in one or more activity purposes along with the amount of time to invest in each chosen activity purpose, and allows generic correlation structures to account for common unobserved factors that might impact the choice of multiple alternatives. The 2010 American Time Use Survey (ATUS) data is used for the empirical analysis. A major finding of the study is that the presence of a child in dual-earner households not only leads to a reduction in in-home non-work activity participation (excluding child care activities) but also a substantially larger decrease in out-of-home non-work activity participation (excluding child care and shopping activities), suggesting a higher level of mobility-related social exclusion relative to overall time-use social exclusion. To summarize, the results in the paper underscore the importance of considering household structure in activity-based travel demand models, as well as re-designing work policies in the United States to facilitate a reduction in work-family conflict in dual-earner families.     

消除新闻传媒舆论监督的盲区

目前我国新闻传媒舆论监督的最主要问题，是存在监督的盲区，即监督之光不能照射到某些监督对象。能进入盲区的，主要有传媒的主办和主管机构，传媒的社会管理和控制机构，对传媒的生产要素、经营活动有较大影响的组织机构，这些机构中的人物以及对这些机构有一定影响的人物，新闻传媒及其内部的有关“把关人”。产生结果的途径是使监督者不能、不敢和不愿监督。消除盲区的方法主要有减少可进入盲区的监督对象，缩小、减轻、阻止监督对象的消极影响，加大盲区的错位，形成“无影灯”效应。最根本的措施是提高党政干部、新闻传媒工作者和广大公众的传媒素养，包括对新闻传媒功能的认识，对新闻传媒与政治、经济、社会和文化的关系的认识，对新闻传媒实施舆论监督的认识，和全面发挥新闻传媒积极作用的社会责任心。
