The Public

Civil drones are becoming ever more present in public perception. Ranging from parcel delivery to wildlife protection and from precision farming to law enforcement, many applications are said to have market-changing potential. Against this background, nations and institutions around the world are trying to keep up with the dynamic technological developments by means of rules and regulations. Since all parties involved expect a strong increase in both the number of drones and the range of their uses, there is a rising interest in the public acceptance of these vehicles. Widespread acceptance can promote the dissemination of new technologies. Conversely, citizens' concerns about the use of drones in their daily environment may pose barriers to the further proliferation of civil drones, especially in urban areas. The psychoacoustic properties of the vehicles have repeatedly been discussed as being one such limiting factor. This paper discusses results of a representative national study on the social acceptance of civil drones, taking a closer look at effects of information about drones as potential means to foster public acceptance. The findings underline the role of well planned information campaigns as well as community engagement in managing the contribution of drones in future urban soundscapes.

Emerging Treatments

As a public agency, interacting with and understanding the public’s perspective regarding agency activities is an important endeavor for the Indiana Department of Transportation (INDOT). Although INDOT conducts a biennial customer satisfaction survey, it is occasionally necessary to capture public perception regarding more specific aspects of INDOT’s activities. In particular, INDOT needs an effective way to measure and track public opinions and awareness or understanding of a select set of its traffic engineering practices. To evaluate public acceptance of specific INDOT traffic engineering activities, a survey consisting of 1.000 adults residing within the State of Indiana was conducted. The survey population was representative in terms of age and gender of the state as of the 2010 U.S. Census. The survey was administered during the months of July and August 2020. Public awareness regarding emerging treatments not currently implemented in Indiana is low and opposition to the same new technologies is prominent. Older or female drivers are less likely to be aware of emerging treatments, and older drivers are more likely to oppose potential implementation of these treatments. Although roundabouts are commonplace in Indiana, multi-lane roundabouts remain controversial among the public. Regarding maintenance and protection of traffic during work zones and considering full or partial roadway closure, public preference is for partial closure; this preference is stronger in rural areas. The public equally agrees and disagrees that INDOT minimizes construction related traffic delays. Approximately 76% of Indiana drivers believe themselves to above average drivers, while an additional 23% believe themselves to be average. Driver perceptions of average highway speeds speed are not aligned with posted speed limit as the perceived average speed on Indiana’s urban freeways and rural and urban state highways is considerably higher than the actual speed limit.

<p>The increase of the metropolises stresses the urban areas and intensive planning works is necessary. Therefore, the development of new technologies and methodologies able to explore the subsoil and manage its resources in urban areas becomes an important source in terms of saving time and money. In the last decade, a new subdiscipline in the Applied Geophysics started: Urban Geophysics (Lapenna, 2017). Urban Geophysics analyzes the contribute, in terms of limits and potentialities, that geophysical methodologies can give for providing useful information about the subsoil, environment, buildings and civil infrastructures and supporting the public administrations in planning interventions in urban scenarios.</p><p>This work introduces a laboratory test, that was performed at the Hydrogeosite CNR-IMAA laboratory of Marsico Nuovo (Basilicata region, Italy). The test consisted in a multisensor geophysical application on an analogue engineering model. Thanks to the possibility to work in laboratory conditions, a detailed knowledge of the structure was available, providing great advantages for assess the capability of the geophysical methodologies for analyze engineering issues, regarding the characterization of the infrastructural critical zone placed at the interface soil-structure. For this purpose, geoelectrical and electromagnetic methodologies, including Cross hole Electrical Resistivity Tomography and Ground Penetrating Radar, were used to characterize the geometry of the foundation structures and the disposition of the rebar for the reinforced concrete frame. Finally, new geophysical approaches were applied in order to define the corrosion rate of reinforcement.</p>

Based on people’s enthusiasm and economical reasons, space commercialization will get more momentum in the future, and eventually reach a full commercialization status, a public-oriented human space commercialization (POHSC) where the public freely participate and purchase space products and services. In this study, the authors conduct a survey-based research model to investigate public perception on POHSC in the human space exploration (HSE) context. The authors want to identify what factors influence public acceptance and adoption of POHSC, and to evaluate public willingness to pay for future services provided by POHSC. For these objectives, the authors develop the concept of ‘eMerge’, a conceptualized mobile device-based application tool with which the public access and pay for their services. The authors also propose the Technology Acceptance Model with ‘eMerge’ specific (TAMe). The results show that public perceptions are strongly affected by perceived availability, perceived usefulness, and perceived enjoyment to use ‘eMerge’. The Perceived availability and perceived enjoyment have significant effect on public motivation to use ‘eMerge’ by forming a positive attitude toward intention to use it. It also shows that the public have very high expectations and enthusiasm on POHSC in terms of their estimated spending on ‘eMerge’. These results can be used as base knowledge in POHSC for future R&D and commercialized technology development.

Nuclear energy projects continue to evoke strong emotional responses from the general public throughout the world. High Temperature Gas-Cooled Reactor (HTGR) technology offers improved safety and performance characteristics that should enhance public acceptance but is burdened with demonstrating a different set of safety principles. This paper summarizes key issues impacting public acceptance and discusses the importance of openly engaging the public in the early stages of new HTGR projects. The public gets information about new technologies through schools and universities, news and entertainment media, the internet, and other forms of information exchange. Development of open public forums, access to information in understandable formats, participation of universities in preparing and distributing educational materials, and other measures will be needed to support widespread public confidence in the improved safety and performance characteristics of HTGR technology. This confidence will become more important as real projects evolve and participants from outside the nuclear industry begin to evaluate the real and perceived risks, including potential impacts on public relations, branding, and shareholder value when projects are announced. Public acceptance and support will rely on an informed understanding of the issues and benefits associated with HTGR technology. Major issues of public concern include nuclear safety, avoidance of greenhouse gas emissions, depletion of natural gas resources, energy security, nuclear waste management, local employment and economic development, energy prices, and nuclear proliferation. Universities, the media, private industry, government entities, and other organizations will all have roles that impact public acceptance, which will likely play a critical role in the future markets, siting, and permitting of HTGR projects.

The Public

In comparison to fossil fuels that emit greenhouse gases, nuclear power plants are a cleaner energy source that could help to mitigate the problems of climate change. Despite this, the general public often associates nuclear energy with risks that include nuclear accidents, nuclear waste contamination, nuclear weapons proliferation, and many others. People’s experience with the 1979 Three Mile Island incident in Pennsylvania and the 1986 Chernobyl nuclear disaster in Ukraine have caused a sharp decline in public support for nuclear energy over the past few decades. In addition, media images of the 2011 Fukushima-Daichii nuclear accident are still fresh in the minds of the public. These now iconic media images and portrayals have perpetuated a perception of nuclear energy as a risky technology. Against these backdrops, scientists, communication practitioners and other key stakeholders increasingly face an uphill struggle to communicate about nuclear energy as a possible strategy for addressing climate change. Though the general public may reluctantly accept nuclear energy for climate change mitigation, research suggests that messages emphasizing the benefits of nuclear power for energy security and economic growth appear to have greater impact on public acceptance of the technology. Furthermore, public perception of nuclear energy is shaped by a host of other factors such as trust in nuclear governing institutions, knowledge, political inclinations, geographical proximity, and socio-demographic variables. At the same time, nuclear experts and the general public differ in their perceptions of risk, in nature and strength, relative to nuclear energy. Understanding these key differences between the experts and the public, and how beliefs, values, and perceptions influence public acceptance of nuclear energy is necessary to formulate effective public communication and engagement strategies.

Using a big data approach, this study explores the media agenda setting effects in 16 countries on five continents. Agenda setting effects were found to vary across the nations. Our findings provide empirical evidence that individual factors such as Age, Education, Living area, and Political ideologyand national macro variables, including Economic developmentand Media freedom, are associated with the strength of such effects. Results suggest that assessing agenda setting effects needs to be conducted in relation to the economic, political, and media context of a country. This study also proposes an alternative way to measure salience on the public agenda using Issue distance, which arguably allows for capturing the possible interaction between issue relevance to individual audiences and media cueing effects.

Access To Food

One of the problems with agriculture in urban areas is that food access is difficult, while soil conditions for agricultural land are limited and less productive. Currently, the whole world is faced with the Covid-19 pandemic, including in urban areas, so that easy access to food and the availability of safe, cheap, healthy, and nutritious food are essential. Urban farming through hydroponic technology is one of the efforts to procure household food independently. It is expected to support the economy of independent communities—this study aims to analyze the levels of public perception of the application of hydroponic technology. The research was conducted in Tarakan City from April to June 2021. Determining respondents was carried out intentionally, considering that the community had obtained information about hydroponic technology. Data analysis that has been used in answering the research objectives is descriptive qualitative data analysis using a Likert scale to measure the level of public perception of hydroponic technology. The story of perception is determined based on respondents' answers about their knowledge of several perceptions about hydroponic technology. The characteristics of the research respondents consisted of an average age of 30 years, the formal education of the respondents graduated from high school, the average number of family members was four people with the main occupation being non-farmers. The results showed that the public had a heightened perception of the application of hydroponic technology (81.11 percent). The highest perception value is found in the perception that plants grown hydroponically are healthier, the quality of the results is maintained, maintenance is easy and more practical. It has a high selling price compared to those grown conventionally.

Currently, the urban areas become more congested; numerous health concerns such as obesity are becoming more prevalent among urban dwellers followed by lack of exercise. With this situation, provision of adequate areas for exercising to the satisfaction of all is critical with limited space in urban areas. Hence, an ideal solution emerges as ‘walking ways’ where a strip of land is only needed. The interest of walking ways is also developed in Sri Lanka very recently. However, there is no evidence on a research to identify the attributes, should developed along with the walkway to increase the attraction of the users. The main aim of this study is to examine the public perception on attributes of walking avenues in urban areas of Sri Lanka. Data was acquired by a personal-administered questionnaire from a convenience sample of 150 walking trail users on three settings. The descriptive statistics, univariate analysis, hoc multiple comparisons and homogeneous subsets technique were used as methodological analysis. The findings disclose ‘safety’ as the preferred attribute while shading and natural settings significant. An income variation presents that user with above the income level of LKR 65,000 preferred cafeterias providing herbal drinks while the users with below that income level are less interest with the attributes of changing rooms and street vendors. This article fills the gap of identifying user perceptions particular to a novel design concept of walking trail in Sri Lanka with interesting attributes getting more benefits.
