This study analyzes the potential of very high resolution (VHR) remote sensing images and extended morphological profiles for mapping Chestnut stands on Tenerife Island (Canary Islands, Spain). Regarding their relevance for ecosystem services in the region (cultural and provisioning services) the public sector demand up-to-date information on chestnut and a simple straight-forward approach is presented in this study. We used two VHR WorldView images (March and May 2015) to cover different phenological phases. Moreover, we included spatial information in the classification process by extended morphological profiles (EMPs). Random forest is used for the classification process and we analyzed the impact of the bi-temporal information as well as of the spatial information on the classification accuracies. The detailed accuracy assessment clearly reveals the benefit of bi-temporal VHR WorldView images and spatial information, derived by EMPs, in terms of the mapping accuracy. The bi-temporal classification outperforms or at least performs equally well when compared to the classification accuracies achieved by the mono-temporal data. The inclusion of spatial information by EMPs further increases the classification accuracy by 5% and reduces the quantity and allocation disagreements on the final map. Overall the new proposed classification strategy proves useful for mapping chestnut stands in a heterogeneous and complex landscape, such as the municipality of La Orotava, Tenerife.

Subject The impact of recent corruption allegations. Significance An investigation into tax evasion at one of Chile's leading business groups, whose principal owners are currently on remand, has led to revelations of what may prove to be quite widespread illegal political financing. The revelations raise questions about the country's reputation for transparency, and have the potential to trigger the country's worst political crisis since the restoration of democracy in 1990. Impacts The crisis of confidence may delay pending reforms and a recovery in growth and investment. The scandal is accentuating Chileans' with income inequality which, despite lower poverty, remains very high. As investigations proceed, political financing could dominate the public agenda into next year.

The effect of the media over the society is the object of the studies of the social science of communication since its founding up to today. A lot of scientific theories explore, argues and explain the connections and the effect of the media over the public. The purpose of this paper is to evident and argument the effect that the media, especially the TV programming has on the politicization of the Kosovar society, which is manifested in a large number of conversations that have to do with politics. In order to argument the direct link between the content of the TV programming (as a media) and political conversations among citizens, this writing will present the results of measuring the contents of the four biggest TV stations in Kosovo: RTK, KTV, RTV 21 and Klan Kosova. What was measured is the amount of programs that have political content within a week at the time when the viewing is at its peak, or in what is known as prime time, from 17 00 to 24 00 h. It also involves an opinion poll of the public which was asked about the influence of the content of TV programs on their daily conversations. The results of programming contents prove a very high percentage of political programs on these four TV stations (RTK 1, KTV, RTV 21 and Klan Kosova), whereas the results of the public polling prove the direct influence of the contents of this programs on the daily conversations.

Before analysing the role of the mediators in relation to scientific education, I deem it important to provide a short overview on how scientific museums evolved from the early curiosity cabinets to the modern web cast. Although the term “museum” is no longer adapted to the new structures employed for the diffusion of scientific and technical culture, the evolution of the means of presentation has indeed led to several forms of human mediation. This is of course the main topic we are going to take into consideration today, as it is an important element for the impact our exhibitions may have on the public. Decisions and choices vary from structure to structure for reasons that are sometimes justifiable but that are more often than not economic in nature, since wages, which are in any case very high no matter which country plays host, come to bear heavily especially on the budget of small and medium-sized structures.

This paper investigates an applied participatory mapping research project that enables members of the public to crowdsource information for Canada’s first community spatial database documenting contemporary changes to local news outlets. This data is presented on the Local News Map, which locates where news organizations are closing or cutting back services and where new outlets are launched or services are increased. The tool, released in mid-2016 by Canadian academics, is a web-based, interactive platform that displays map markers and descriptive information about changes to local television, radio, online sites and newspapers dating from 2008 to the present. Map filters allow users to select and view specific information about these changes. We explore the impact of the project, demonstrating that the map has enriched the public sphere by generating robust empirical data on news outlets that have shut down or launched or increased/decreased service in their communities. Specifically, we found strong and ongoing demand from journalists who use the platform’s data to provide context for stories about the ongoing disruption in the local news sector. We also identify other impact indicators for further investigation.

Deep convolutional neural networks (DCNNs) have been used to achieve state-of-the-art performance on land cover classification thanks to their outstanding nonlinear feature extraction ability. DCNNs are usually designed as an encoder–decoder architecture for the land cover classification in very high-resolution (VHR) remote sensing images. The encoder captures semantic representation by stacking convolution layers and shrinking image spatial resolution, while the decoder restores the spatial information by an upsampling operation and combines it with different level features through a summation or skip connection. However, there is still a semantic gap between different-level features; a simple summation or skip connection will reduce the performance of land-cover classification. To overcome this problem, we propose a novel end-to-end network named Dual Gate Fusion Network (DGFNet) to restrain the impact of the semantic gap. In detail, the key of DGFNet consists of two main components: Feature Enhancement Module (FEM) and Dual Gate Fusion Module (DGFM). Firstly, the FEM combines local information with global contents and strengthens the feature representation in the encoder. Secondly, the DGFM is proposed to reduce the semantic gap between different level features, effectively fusing low-level spatial information and high-level semantic information in the decoder. Extensive experiments conducted on the LandCover dataset and the ISPRS Potsdam dataset proved the effectiveness of the proposed network. The DGFNet achieves state-of-art performance 88.87% MIoU on the LandCover dataset and 72.25% MIoU on the ISPRS Potsdam dataset.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.

The Swiss Armed Forces (SAF), as part of a democratic system, depends on legitimacy. Democracy, legitimacy and the public are closely connected. In the public sphere the SAF need to be visible; it is where they are controlled and legitimated by the citizens, as part of a deliberative discussion in which political decisions are communicatively negotiated. Considering this, the meaning of political communication, including the SAF’s communication, becomes obvious as it forms the most important basis for political legitimation processes. Social media provide a new way for the SAF to communicate and interact directly with the population. The SAF’s social media communication potentially brings it closer to the people and engages them in a dialogue. The SAF can become more transparent and social media communication may increase its reputation and legitimacy. To measure the effects of social media communication, a survey of the Swiss internet population was conducted. Based on this data, a structural equation model was defined, the effects of which substantiate the assumption that the SAF benefits from being on social media in terms of broadening its reach and increasing legitimacy values.
