This document develops a methodology that evaluates the impact on the environment of the rivers produced by the creation of civil infrastructures. The methodology is based on the two-dimensional hydrodynamic calculation by using shallow water equations both in the conditions prior to the creation of the infrastructure, and in the new conditions after the infrastructure is created. Subsequently, several characteristics, such as water depth and velocity, among others, are compared between the initial and final conditions, and a two-dimensional zoning of the changes observed is obtained. The methodology herein presented is useful to verify the impact that the implantation of different infrastructures around the river currents could produce. In addition, it is also relevant for carrying out a study taking into account different infrastructure options related to river currents, as well as for selecting the most suitable one. By using the methodology presented, changes on the regime of the currents caused by the infrastructures can be deduced, including a qualitative and quantitative zoning of the changes, with a special emphasis on some characteristics, such as depth and velocity. The methodology is applied in a case study for the creation of a road bridge over the Jalon River in Spain.

The mental wellness of university students can be critical for their success. In an attempt to minimize stress for students, many universities have implemented a policy for a fall break with limited evidence to support its intended outcomes. This case study offers a critical appraisal of the formation of the fall break policy at one medium sized comprehensive university using qualitative and quantitative forms of evidence triangulated from (1) University Student Union survey, (2) document analysis and; (3) informant interview. The lack of uniformity on how the fall break is labelled, the timing of the break and its evaluation emerged as design flaws in the creation stage that perhaps, could have been mitigated if faculty and student voices were included in policy creation decisions.

The evolution of information and communication technologies has changed the way we relate to each other and how we build our knowledge. This creates challenges for education systems, as school must provide all students with the educational experiences that will enable them to develop the skills reflected in the profile of the 21st-century student on com  pletion of compulsory schooling. It is up to teachers to find new ways of teaching, making the most of the resources and digital tools made available by mobile technologies. Technology can make a significant contribution to increasing students' motivation because it is closer to what they like and use in their daily lives. And this introduction of technology into the classroom can promote student-oriented teaching, which contributes to the development of skills such as autonomy, critical thinking and self-esteem. One of the areas that can contribute to this paradigm shift is the creation of experiences in immersive learning environments such as Transmedia Storytelling. Immersive learning environments can favour the creation and implementation of projects that promote reading skills in schools. This is the focus of this article. The aim of this study is to evaluate the impact of transmedia storytelling on the level of motivation of students and on the improvement of pedagogical practices implemented by the teachers involved. This case study was carried out in the subject of Portuguese in three 7th-grade classes of a school from the Médio Tejo region. The results obtained suggest a high level of motivation of students and teachers. The latter recognise that pedagogical routes using Transmedia Storytelling contribute to the motivation, autonomy and improvement of students' learning.

Abstract. China is one of the countries that is most seriously affected by storm surges. In recent years, storm surges in coastal areas of China have caused huge economic losses and a large number of human casualties. Knowledge of the inundation range and water depth of storm surges under different typhoon intensities could assist predisaster risk assessment and making evacuation plans, as well as provide decision support for responding to storm surges. Taking Pingyang County in Zhejiang Province as a case study area, parameters including typhoon tracks, radius of maximum wind speed, astronomical tide, and upstream flood runoff were determined for different typhoon intensities. Numerical simulations were conducted using these parameters to investigate the inundation range and water depth distribution of storm surges in Pingyang County considering the impact of seawall collapse under five different intensity scenarios (corresponding to minimum central pressure values equal to 915, 925, 935, 945, and 965 hPa). The inundated area ranged from 103.51 to 233.16 km2 for the most intense typhoon. The proposed method could be easily adopted in various coastal counties and serves as an effective tool for decision-making in storm surge disaster risk reduction practices.

<p>Law Number 32 Year 2004 on Regional Government article 4 stated that the formation of regions could be in the form of merging or splitting one area into two or more regions. The implementation of the splitting or extension will effect the improvement of community welfare, acceleration of public services, and management of regional potential. This study is aimed (1) to describe the consideration of Sungai Penuh City extension from Kerinci Regency; (2) to analyze the influences of city extension in increasing economic growth and potential development of Sungai Penuh City Area; and (3) to understand the impact of city extension on development of Sungai Penuh periphery area. This study conducts case study research with using qualitative and quantitative method, and determines informant using purposive sampling technique. Qualitative analysis is used to achieve the first and the third research purpose, and quantitative analysis is used to achieve the second research purpose. Results stated that the implementation of Sungai Penuh City extension is implemented by considering physical condition, regional function, economy, and social community. Economic growth of Sungai Penuh City after city extension increased 3.13% during 2010 to 2016. The economic growth was also supported by the increase of Human Development Index. The trade sector becomes a potential sector to be developed in Sungai Penuh City. City economic growth has an impact on development of its periphery area through the availability and accessibility of educational, health and agricultural infrastructure.</p>

The aim of this chapter is to evaluate the role of the designer as a socially responsible agent and the impact that artefacts created by designers have. The goal is to understand if the designer can help preserve local memories, as well as assess whether co-working influences how they emerge in the project. The awareness of the designer as a social agent, who works in collaboration with various agents towards the creation of value-added artefacts, is essential nowadays. As a case study, we bring the project developed by the Designlab4u laboratory in the village of Alhos Vedros, were the cultural and artistic itinerary of the village was designated as a place of memory. Ultimately, the intention is to evaluate whether or not the work developed for the exhibition was a driver of local memories.

Entrepreneurship is recognized as an engine for the economy. However, Latin America must promote higher opportunities for the creation of new businesses, especially for technology-based ventures. In this sense, the Center for Global Innovation and Entrepreneurship (CGIE) of the University of Texas at Austin offers a Master of Science in Technology Commercialization (MCCT) that prepares students with methodologies to promote the creation of new businesses in Mexico. This study aims to know the contribution of training to the creation of new companies, and its role in the innovation and the technology transfer processes, from the viewpoint of the participants. This research presents a case study that analyzes the impact of the MCCT through the analysis of the data of a survey answered by 109 former students of this center. Findings show that the methodologies developed by the MCCT allow the creation of technology-based enterprises and entrepreneurial skills in students. This study presents good practices that can be emulated by other countries in the region, as well as recognizing the great value the role of higher education in creating synergies between actors of the innovation ecosystem that strengthen social and economic growth.

One of the priority lines of action in Poland is to increase energy production from renewable energy sources (RESs). Based on the “Poland’s national energy and climate plan for the years 2021–2030”, Poland aims to achieve 21%–23% of RES share in gross final energy consumption by 2030. While coal is still the most important source of energy, new technological and organisational solutions for increasing RESs are being tested and implemented. Therefore, the creation of energy clusters based on the idea of urban and industrial symbiosis was first proposed by the Ministry of Energy in 2016. To date, there are 66 clusters in different regions in Poland, but only a few of them are active and innovative. One of them is located in the city of Zakopane, a mountain resort, which attracts about 3 million tourists annually and has developed the wide-ranging use of geothermal sources for energy supply and recreation. The paper aims to analyse the impact of the creation of energy clusters on the city’s development, including economic, social, and environmental aspects. The “willingness to pay” (WTP) method was used to calculate the impact of air pollution on Zakopane and to compare it with the Polish average to estimate the significance of the transformation to RESs in this tourist city. The results from the studies are as follows: health cost per capita in Zakopane is between 252.07 and 921.30 euro. The investigations presented can be the basis for recommendations in strategic documents in the field of regional development and environmental protection, especially on the use and promotion of urban symbiosis for increasing use of RESs.

In some of Camden, NJ’s most underdeveloped neighborhoods, new investment is perceived as a catch-22. Such investment is badly needed, but residents fear gentrification and the creation of white spaces. Our study examines that puzzle, that residents protest badly needed investment, using ethnographic and interview data from residents and Camden, NJ, as a case study for examining community understanding of gentrification. In doing so, we draw upon gentrification literature that focuses on displacement pressure and exclusionary displacement, but argue that the Camden case points towards a different dimension of gentrification. Our findings show how (1) exclusion and “unwelcomeness” created by the development of white spaces is conceptualized by residents as being distinct from the impact such exclusion has on future displacement and (2) that residents internalize that exclusion from white spaces, dampening their support and increasing their resistance for new development. Our findings represent a contribution to the discussion on displacement pressure, which focuses primarily on exclusion through financial and economic pressure on residents, and shows that racialized exclusion is, itself, a fundamental element of residential fear of gentrification. We point to an opportunity to address fears of gentrification not only through economic means but also by focusing on issues of access and exclusion in urban space as a direct response to such residential fears.
