The Edmonton–Calgary corridor transportation study is an example of multimodal intercity passenger transportation planning in a low-density corridor. This represents a departure from most corridor studies, which have been conducted in the most intensively travelled and densely populated regions. The study provided the background data, information, and analysis to facilitate transportation planning in the Edmonton–Calgary corridor region. A wide range of capital-intensive alternatives (particularly for the rail and air modes) and a number of transportation system management alternatives are related to transportation issues in the corridor region in a multimodal systems analysis framework.This paper discusses a number of unique approaches used in the study that were the result of the need to deal with the low-density aspects, the need to consider both regional and intercity travel, and the inherent design of the study. These include its iterative approach to the analysis, its handling of the demand and cost analysis, its consideration of multimodal impacts, and the emphasis on identifying key issues and resulting strategic choices. The success and drawbacks of these methodologies are reviewed.The paper also reviews the major findings of the study, many of which can be extended to a more general context: a competitive market analysis may be of little interest in low-density regions; new technologies tend to bias even further the imbalance between intercity and regional transportation service; the automobile has a key role to play in regional transportation; for many transportation needs the intercity bus is an economical and efficient mode; and an improved rail service is an uncertain and long-term venture, which could detrimentally affect all intercity bus service in the region.

<p>The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models, coupled with the local land cadastre. The novelty of these studies is that local agronomists have immediate access to a wide range of soil information by clicking on a field parcel shown in this digital interface and, therefore, can suggest an appropriate treatment (e.g. liming, manure incorporation, desalination, application of proper type and quantity of fertilizer) depending on the field conditions and cultivated crops. A specific case study is presented in the current work with regards to the construction of the digitized Soil Map of the regional unit of Kastoria. The potential of this map can easily be realized by the fact that the mapping of the physicochemical properties of the soils in this region provided delineation zones for differential fertilization management. An experiment was also conducted using remote sensing techniques for the enhancement of the fertilization advisory software database, which is a component of the digitized map, and the optimization of nitrogen management in agricultural areas.</p>

Abstract How will advances in digital technology affect the future of human rights and authoritarian rule? Media figures, public intellectuals, and scholars have debated this relationship for decades, with some arguing that new technologies facilitate mobilization against the state and others countering that the same technologies allow authoritarians to strengthen their grip on power. We address this issue by analyzing the first game-theoretic model that accounts for the dual effects of technology within the strategic context of preventive repression. Our game-theoretical analysis suggests that technological developments may not be detrimental to authoritarian control and may, in fact, strengthen authoritarian control by facilitating a wide range of human rights abuses. We show that technological innovation leads to greater levels of abuses to prevent opposition groups from mobilizing and increases the likelihood that authoritarians will succeed in preventing such mobilization. These results have broad implications for the human rights regime, democratization efforts, and the interpretation of recent declines in violent human rights abuses.

This interdisciplinary collection investigates the forms that authority assumed in nineteenth-century Ireland, the relations they bore to international redefinitions of authority, and Irish contributions to the reshaping of authority in the modern age. At a time when age-old sources of social, political, spiritual and cultural authority were eroded in the Western world, Ireland witnessed both the restoration of older forms of authority and the rise of figures who defined new models of authority in a democratic age. Using new comparative perspectives as well as archival resources in a wide range of fields, eleven chapters show how new authorities were embodied in emerging types of politicians, clerics and professionals, and in material extensions of their power in visual, oral and print cultures. Their analyses often eerily echo twenty-first-century debates about populism, the suspicion towards scholarly and intellectual expertise, and the role of new technologies and forms of association in contesting and recreating authority. Several contributions highlight the role of emotion in the way authority was deployed by figures ranging from O’Connell to Catholic priests and W.B. Yeats, foreshadowing the perceived rise of emotional politics in our own age. This volume stresses that many contested forms of authority that now look ‘traditional’ emerged from 19th-century crises and developments, as did the challenges that undermine authority.

Ceramic Manufacturing

Computer assisted designing (CAD) is well known for several decades and employed for ceramic manufacturing almost since the beginning, but usually employed in the first part of the projectual ideation processes, neither in the prototyping nor in the manufacturing stages. The rapid prototyping machines, also known as 3D printers, have the capacity to produce in a few hours real pieces using plastic materials of high resistance, with great precision and similarity with respect to the original, based on unprecedented digital models produced by means of modeling with specific design software or from the digitalization of existing parts using the so-called 3D scanners. The main objective of the work is to develop the methodology used in the entire process of building a part in ceramics from the interrelationship between traditional techniques and new technologies for the manufacture of prototypes. And to take advantage of the benefits that allow us this new reproduction technology. The experience was based on the generation of a complex piece, in digital format, which served as the model. A regular 15 cm icosahedron presented features complex enough not to advise the production of the model by means of the traditional techniques of ceramics (manual or mechanical). From this digital model, a plaster mold was made in the traditional way in order to slip cast clay based slurries, freely dried in air and fired and glazed in the traditional way. This experience has shown the working hypothesis and opens up the possibility of new lines of work to academic and technological levels that will be explored in the near future. This technology provides a wide range of options to address the formal aspect of a part to be performed for the field of design, architecture, industrial design, the traditional pottery, ceramic art, etc., which allow you to amplify the formal possibilities, save time and therefore costs when drafting the necessary and appropriate matrixes to each requirement.

This article examines a paradigmatic change of contemporary art education in the context of visual culture and focus to the integrity of arts in formal and informal art education. The article is based on an international research “Contemporary art and visual culture in education” which reveals the problematic aspects of contemporary arts and visual culture in education in general. The research method was the discourse analysis of the participants and researchers, who presented the insights in reflective groups and during the interview with teachers and educators.This paper explores how contemporary cultural context and the spread of visual culture provide preconditions for changes in art education. The aim of the article is to analyze theproblems and perspectives of integral arts education in formal and non-formal education: what the educational challenges and opportunities appear in the context of contemporary art and visual culture? How the integral arts could be realized in art education practice in different arts disciplines and areas of education?Contemporary art and visual culture is increasingly multidimensional, the wide range of visual art forms integral with per formative arts, new technologies and media merge the limits between the arts disciplines. That becomes relevant pedagogical problem with the fact that arts education is traditionally allocated to the separate arts subjects such as music, art, theatre, dance, which also can also be divided into separate areas. This subject segregation of the school curriculum and strong subject orientation limits multimodal contemporary arts education. Secondary Education programs provide opportunities for several options of arts education disciplines (photography, cinema art, graphic design, contemporary music technologies), but it needs special resources for the schools and professional teachers. Many schools follow on traditional model of teaching art and still focusing on simple interpretation of modern artworks, different media and technical skills.Contemporary model of teaching integrated arts and visual culture in education is challenging, because it is based on visual literacy and critical thinking skills, it emphasizes inquiry-based education, a critical understanding of contemporary art practices, problem solving and creating new valuable ideas. Knowledge and experiences came from various sources: formal, non-formal, accidental, individual.Great potential for contemporary art education has non-formal art education programs and projects. Successful project-based initiatives in art education have been excellent examples of arts integration.Artists and other creative people involved into a process of education, their collaboration with schools and communities could initiate some interdisciplinary and collaborative practices. Non-formal arts education environment creates more space for creativity, freedom and diversity. Additional arts education programs, museum and gallery education, artistic competitions and international projects allows for the wider development of arts education. Art education in the new age requires changing attitudes towards learning and teaching, changing roles of the educator and new learning environments.

В статье дан обзор современного состояния и тенденциозного развития виноградарской отрасли Афганистана. Виноград выращивается практически в каждой части страны, от Кандагара до Такара и Фарьяба. Наиболее интенсивно виноград возделывают в провинциях Кабул, Парван, Каписа, Кандагар, Гильменд, Джавзян, Герат и Газни. Но в большинстве районов страны культура выращивается не для коммерческого использования, а для семейного потребления. В основном весь виноград Афганистана принадлежит к подвиду Vitis vinifera sativa D.C.. В стране в наличии большое разнообразие доступных сортов (более 100), но самыми распространёнными являются три местных сорта столового направления использования: Шиндохани, Кишмиш белый и Тайфи розовый. При этом сорта Шиндохани и Кишмиш белый еще используются для приготовления изюма. К другим распространенным сортам винограда относятся Хусайне, Аскери, Голадан, Спен Манга, Надери и Бедана Кишмиш сиах (черный без косточек). Также вводятся в производство такие новые коммерческие сорта как Thompson Seedless, Red Globe, Cardinal, Emperor, Fantasy, Crimson Seedless, Flame Seedless, Ruby, Ribier и Black Emerald. В экспорте Афганистана виноград занимает 4%. В Афганистане виноградная лоза в основном возделывается по местной традиционной системе - на земляных курганах с головчатой формировкой. Используется также система «земля-решетчатая». Производственная система виноградарства Афганистана, его культурные практики, сортимент и послеуборочный процесс все еще традиционны. Поэтому для достижения более высоких результатов необходимо ориентироваться на международные стандарты качества, импортировать и распространять новые технологии, координировать процесс между всеми производителями виноградной продукции, повышать их грамотность.The article provides an overview of modern condition and development trends of the viticulture industry in Afghanistan. Grapes are cultivated in almost every part of the country, from the south to Kandahar and to the north to Takar and Faryaba. The most intensive cultivation areas are the provinces Kabul, Parvan, Kapisa, Kandahar, Helmand, Javzyan, Herat and Ghazni. In most parts of the country, grapes are grown not for commercial use but for family consumption. Most of grape varieties in Afghanistan belong to Vitis vinifera sativa D.C. The country has a wide range of available varieties (more than 100), but the most common are three local varieties: ‘Shindokhani’, ‘Kishmishi bely’ and ‘Typhi rozovy’. These are table varieties. At the same time, ‘Shindokhani’ and ‘Kishmishi bely’ are also used for raisin production. Other common grape varieties are ‘Hussaini’, ‘Askari’, ‘Goladan’, ‘Spen Manga’, ‘Naderi’ and ‘Bedana Kishmishi siah’ (black seedless). New commercial varieties ‘Thompson Seedless’, ‘Red Globe’, ‘Cardinal’, ‘Emperor’, ‘Fantasy’, ‘Crimson Seedless’, ‘Flame Seedless’, ‘Ruby’, ‘Ribier’ and ‘Black Emerald’ are being introduced into cultivation, too. Grapes account for 4% of the country’s total exports. In Afghanistan, grapes are mainly cultivated according to the local traditional system on mounds of earth with head training. ‘Earth-lattice’ trellis is also used. In Afghanistan, grape production, cultural practices, assortment and post-harvest process are still traditional. Therefore, to achieve better results, it is necessary to focus on international quality standards, to import and disseminate new technologies, to coordinate the process with all producers of grape products, and to increase their professional skills.

Transportation planning is an area of public policy that is increasingly recognized for having a significant impact on human health and well-being. Passengers all across the world are choosing bus transit as one of the most cost-effective ways of transportation. The number of passengers who use this mode of transportation is steadily increasing. According to statistics, the bus was India's most popular mode of transportation in 2014. A bus was viewed as a mode of transportation by 66 percent of families in rural areas and 62 percent of households in urban areas. With increased demand, there is a concern about efficiently organizing this service. Because a lack of planning can generate major problems in the real world, such as traffic jams and high operating expenses, it is a source of concern for corporate and government entities who provide this service. In this paper, a review on various bus transit planning approaches and stages and methodologies used in each stage of the customized bus planning strategy is presented. This study will assist bus service organizing entities, whether private or public, in efficiently organizing bus service

AbstractA wide range of anthropogenic structures exist in the marine environment with the extent of these set to increase as the global offshore renewable energy industry grows. Many of these pose acute risks to marine wildlife; for example, tidal energy generators have the potential to injure or kill seals and small cetaceans through collisions with moving turbine parts. Information on fine scale behaviour of animals close to operational turbines is required to understand the likely impact of these new technologies. There are inherent challenges associated with measuring the underwater movements of marine animals which have, so far, limited data collection. Here, we describe the development and application of a system for monitoring the three-dimensional movements of cetaceans in the immediate vicinity of a subsea structure. The system comprises twelve hydrophones and software for the detection and localisation of vocal marine mammals. We present data demonstrating the systems practical performance during a deployment on an operational tidal turbine between October 2017 and October 2019. Three-dimensional locations of cetaceans were derived from the passive acoustic data using time of arrival differences on each hydrophone. Localisation accuracy was assessed with an artificial sound source at known locations and a refined method of error estimation is presented. Calibration trials show that the system can accurately localise sounds to 2m accuracy within 20m of the turbine but that localisations become highly inaccurate at distances greater than 35m. The system is currently being used to provide data on rates of encounters between cetaceans and the turbine and to provide high resolution tracking data for animals close to the turbine. These data can be used to inform stakeholders and regulators on the likely impact of tidal turbines on cetaceans.

The use of ride control systems on high speed vessels has become the norm within many industries, producing better seakeeping that in turn provides a more comfortable and operationally effective vessel. Commercial ferry designers have been at the forefront of adoption of new technologies notably with early adoption of T-foils and interceptors. These devices have been taken up by others, for example offshore crew boats and frontline naval warships. The range of vessel types has also expanded with more industries adopting different hull designs including catamarans and trimarans. Ride control systems have developed alongside innovative designers producing for example combined lifting foil and ride control systems, lifting T-foil systems, retractable T-foils. This paper will review the different ride control devices including fins, trim tabs, interceptors, T-foils (including retractable T-foils) and lifting foils. As well as technical aspects, the discussion will consider costs, ease of installation, operational and maintenance requirements and material choice. Extensive examples from a wide range of industries will be presented. By the end of the talk, delegates will have a broad understanding of the options available to them in improving the seakeeping of their vessels.
