Citizen participation of rainwater harvesting is a valuable practice to mitigate problems such as groundwater mining, land subsidence, and urban flooding cause by global warming and urbanization in japan. In this study, we defined rainwater harvesting as activities carried out by citizens aimed at using rainwater, and examining the hypothesis that people’s willingness to work (WTW) and willingness to pay (WTP) for rainwater harvesting differ depending on their lifestyles and experience of using rainwater. We conducted a survey over the internet in August 2017, covering 1,794 people in Japan. The survey questions addressed three areas: (1) respondents’ lifestyles, (2) their experience of using rainwater, and (3) their willingness to participate in rainwater harvesting. As the results, we concluded that activities that ask for time or labor are preferable to those that ask for money, and people’s WTW and WTP do in fact differ based on lifestyle. Older people, full-time housewives/husbands, and non-workers have comparatively more time for participating in rainwater harvesting, and showed more interest in activities that ask for time or labor. Men and owners of single-family homes have higher annual incomes and thus greater WTP for rainwater harvesting. Moreover, WTW and WTP differed depending on whether a person had experience using rainwater. Men and younger people having more experience than women and elderly people.　However, there were only 10% of the public has experience using rainwater, which shows that　there is room to further promote rainwater harvesting.

Greywater Reuse

This article aims to estimate the reduction of potable water consumption and sewage generation in the city of Joinville, southern Brazil. Four strategies were considered to promote potable water savings: replacement of conventional toilets with dual-flush ones, greywater reuse, rainwater harvesting, and the combination of these three strategies. Residential, public, and commercial sectors were assessed. The potential for potable water savings ranged from 1.7% to 50.5%, and the potential for sewage generation reduction ranged from 2.1% to 52.1%. The single-family residential sector was the most representative for water savings and sewage generation reduction. The public sector would be the least contributor to such reductions. It was found that in the city of Joinville, for low non-potable water demands, greywater reuse was the most viable strategy to save water. When non-potable demand is high and there is a large catchment area, it is recommended to install rainwater harvesting systems. It was concluded that there is a high potential for potable water savings and reduction of sewage generation if measures were adopted in Joinville, but it is necessary to evaluate which strategy is the most appropriate for each building.

More than entertainment: YouTube and public responses to the science of global warming and climate change

Youtube Videos

The public receives and presents science-related information on global warming and climate change in many forms, but little is known about how this information is conveyed through the Internet. More specifically, very few studies have considered YouTube videos focusing on climate change. This study provides a better understanding of how this type of information may be disseminated through several levels of analysis. For this purpose, the exact narrative for the 10 most popular videos about climate change was first established by concentrating particularly on the presentation of the science of climate change. Then the public’s responses to and engagement in each video were examined through a semantic analysis of comments on the video. The results indicate that, regardless of the narrative, science-based comments dominated, but often discussed climate change in general instead of specific videos to which they were attached. In the absence of gatekeepers, YouTube users rode the coattails of popular videos about climate change and addended the videos’ messages by highlighting evidence of weak, strong, or politicized science.

Real Time Information

This study investigated citizen participation in live blogs in the changing media ecosystem from the public sphere perspective. The live blog is a web-native, participatory-oriented journalistic genre comprised of brief updates of an event in motion and designed to deliver real-time information from multiple sources about breaking news and scheduled events. To examine participation in this contemporary news format, the current, exploratory study, collected survey responses from 339 volunteers and found that participation was not a motivating factor for readers to engage in live blogging on a deeper level. Other study findings pertaining to participation were also pessimistic, showing that the majority of participants were not personally interested in participating in live blogging. This is an important finding for digital journalism as it implies that the capacity of online platforms to accommodate participation does not necessarily translate into citizens’ willingness to participate.

In recent years, the number of forged videos circulating on the Internet has immensely increased. Software and services to create such forgeries have become more and more accessible to the public. In this regard, the risk of malicious use of forged videos has risen. This work proposes an approach based on the Ghost effect knwon from image forensics for detecting forgeries in videos that can replace faces in video sequences or change the mimic of a face. The experimental results show that the proposed approach is able to identify forgery in high-quality encoded video content.

The Internet was supposed to fragment audiences and make media monopolies impossible. Instead, behemoths like Google and Facebook now dominate the time we spend online—and grab all the profits from the attention economy. This book explains how this happened. It sheds light on the stunning rise of the digital giants and the online struggles of nearly everyone else—and reveals what small players can do to survive in a game that is rigged against them. The book shows how seemingly tiny advantages in attracting users can snowball over time. The Internet has not reduced the cost of reaching audiences—it has merely shifted who pays and how. Challenging some of the most enduring myths of digital life, the book explains why the Internet is not the postindustrial technology that has been sold to the public, how it has become mathematically impossible for grad students in a garage to beat Google, and why net neutrality alone is no guarantee of an open Internet. It also explains why the challenges for local digital news outlets and other small players are worse than they appear and demonstrates what it really takes to grow a digital audience and stay alive in today's online economy. The book shows why, even on the Internet, there is still no such thing as a free audience.

The Public Sphere

Durch den digitalen Medienwandel ist der Begriff der Öffentlichkeit problematisch geworden. Die Debatte fokussiert sich zumeist auf die Frage, ob die sogenannte bürgerliche Öffentlichkeit durch das Internet im Niedergang begriffen ist oder eine Intensivierung und Pluralisierung erfährt. Rudolf Maresch zeichnet die berühmte Untersuchung der Kategorie durch Jürgen Habermas nach und zieht den von ihm konstatierten Strukturwandel der Öffentlichkeit in Zweifel. Dagegen verweist er auf die gouvernementalen und medialen Prozesse, die jede Form von Kommunikation immer schon gesteuert haben. Öffentlichkeit sei daher ein Epiphänomen nicht allein des Zeitungswesens, sondern der bereits vorgängig ergangenen postalischen Herstellung einer allgemeinen Adressierbarkeit von Subjekten. Heute sei Öffentlichkeit innerhalb der auf Novitäts- und Erregungskriterien abstellenden Massenmedien ein mit anderen Angeboten konkurrierendes Konzept. Mercedes Bunz konstatiert ebenfalls eine Ausweitung und Pluralisierung von Öffentlichkeit durch den digitalen Medienwandel, sieht aber die entscheidenden Fragen in der Konzeption und Verteilung von Evaluationswissen und Evaluationsmacht. Nicht mehr die sogenannten Menschen, sondern Algorithmen entscheiden über die Verbreitung und Bewertung von Nachrichten. Diese sind in der Öffentlichkeit – die sie allererst erzeugen – weitgehend verborgen. Einig sind sich die Autoren darin, dass es zu einer Pluralisierung von Öffentlichkeiten gekommen ist, während der Öffentlichkeitsbegriff von Habermas auf eine singuläre Öffentlichkeit abstellt. </br></br>Due to the transformation of digital media, the notion of “publicity” has become problematic. In most cases, the debate is focused on the question whether the internet causes a decline of so-called civic publicity or rather intensifies and pluralizes it. Rudolf Maresch outlines Jürgen Habermas's famous study of this category and challenges his claim concerning its “structural transformation,” referring to the governmental and medial processes which have always already controlled every form of communication. Publicity, he claims, is an epiphenomenon not only of print media, but of a general addressability of subjects, that has been produced previously by postal services. Today, he concludes, publicity is a concept that competes with other offers of mass media, which are all based on criteria of novelty and excitement. Mercedes Bunz also notes the expansion and pluralization of the public sphere due to the change of digital media, but sees the crucial issues in the design and distribution of knowledge and power by evaluation. So-called human beings no longer decide on the dissemination and evaluation of information, but algorithms, which are for the most part concealed from the public sphere that they produce in the first place. Both authors agree that a pluralization of public sphere(s) has taken place, while Habermas's notion of publicity refers to a single public sphere.

Communicative Space

There is a tendency, particularly among Western pundits and technologists, to examine the Internet in almost universally positive terms; this is most evident in any discussion of the medium’s capacity for democratization. While the Internet has produced many great things for society in terms of cultural and economic production, some consideration must be given to the implications that such a revolutionary medium holds for the public sphere. By creating a communicative space that essentially grants everyone his or her own microphone, the Internet is fragmenting public discourse due to the proliferation of opinions and messages and the removal of traditional gatekeepers of information. More significantly, because of the structural qualities of the Internet, users no longer have to expose themselves to opinions and viewpoints that fall outside their own preconceived notions. This limits the robustness of the public sphere by limiting the healthy debate that can only occur when exposed to multiple viewpoints. Ultimately, the Internet is not going anywhere, so it is important to equip the public with the tools and knowledge to be able to navigate the digital space.
