Ensuring service continuity has become a fundamental issue for companies involved in electricity distribution; in particular, isolating the smallest possible portion of the network as a result of faults has long been a primary objective. To this aim, solutions based on logic selectivity have been defined and implemented for an efficient search for the network branch affected by the fault and its subsequent isolation. The authors have recently presented a proposal for the implementation of logic selectivity that exploits the LoRa transmission protocol, an ideal solution in the case of areas not reachable by the currently exploited communication technologies. The present paper, instead, deals with the optimization of some LoRa parameters, which made it possible to exploit network configurations in terms of coverage range, sensitivity and signal-to-noise ratio. The performance of the new configuration has been assessed through a number of tests conducted in the laboratory and on-field, highlighting promising results in terms of both intervention times and reliability. In particular, tests conducted in both rural and urban areas have assured fault isolation times as low as 33 ms (fully compliant with the current regulations) in the presence of the most challenging fault condition.

Agriculture is facing new challenges in rural and urban areas, and Information and Communication Technologies (ICT) may play a significant role. In this chapter, there is a background description of the ICT sector in the interface of urban and rural communities within the framework of agriculture. It describes some case analyses focused in agronomy and social sciences. In agronomy, the focuses are environment, food production, and pollution. In socioeconomics, there is a brief identification of ICT applications such as the collaboration between the university and firms. Considering the heterogeneousness of the analysis, the future research directions include different methods of studies for ICT programs (house of quality, structural organization, and others).

Open University of Palangka Raya (UPBJJ-UT of Palangka Raya) has acknowledged the education-attainment gap between rural and urban areas, and officials have determined ways to connect with students in the far corners of Central Kalimantan. UPBJJ-UT of Palangka Raya has set up study groups (PokJar) through which non urban students acquire university education. Due to its wide range of locations and heterogeneous student populations, PokJar is established through management partnership that constitutes a governing body that oversees the district-wide operation and the delivery of the continuing education programs. On this optimistic basis, the service provided by PokJar administrators becomes central to optimizing quality education in a learning environment where the administrators and students are physically separated. However, the complexity of PokJar service and administrator performance may link to negative perceptions among students. Recognizing the nature of challenges facing PokJar management is expected to usher in the planning of improvement crucial to organizational development that is effective, efficient, accountable, responsive and transparent. This study taps into the quality service, the competence and performance of PokJar administrators of UPBJJ-UT of Palangka Raya in terms of student-perceived values using PLS-SEM method. The overall results address favorable responses, strongly suggesting a good measure of how PokJar administrators� service, competence and performance meet student expectation.

Tourists’ demand for outdoor sport-related activities has been growing in the last decade, leading to the recognition of the outdoor tourism potential of the development of rural and urban areas where the activities could take place. While the literature has recognized this potential, its features and the existing conditions for its practice are often not fully comprehended, mainly due to the lack of measurement systems and performance indicators. This study addresses this gap by proposing a wide-ranging assessment matrix of nine outdoor-related activities, employing northern Portugal as a study area. Based on an exploratory qualitative analysis employing semi-structured interviews with key stakeholders (public, private and third sector), the main contribution of this study lies in the development of the outdoor tourism assessment matrix (OTAM) to collect data. The OTAM matrix aims to identify and assess the conditions, namely the infrastructure and resources, for the practice of outdoor and sport tourism-related activities within the sustainable development pillars. The nine matrices comprising the OTAM allow the identification of the places where the outdoor activities can be practiced, and the conditions under which they can contribute to the definition of the development strategies of outdoor tourism.

To encourage economic development policy makers and practitioners need to understand the backgrounds and objectives of entrepreneurs who own businesses in rural as well as urban areas. In this study rural firms owned by novice, portfolio, and serial founders were compared. In addition, urban firms owned by novice, portfolio, and serial founders were compared. At the founder level of analysis, similarities as well as differences in the personal background, work experiences, reasons leading to the start-up of businesses, and personal attitudes to entrepreneurship of these three types of founders were explored. At the organizational level of analysis, finance, employment and performance differences between the businesses owned by the three types of founders were analyzed. Implications for policy makers and researchers studying entrepreneurial careers and independent businesses over time are discussed.

Past research into the history, state, function and performance contexts of indigenous African musical practices yielded a number of disturbing observations: there was no hope that the practitioners of this genre would ever begin deriving a living out of their art; there was the fear that some indigenous musical practices were nearing extinction because the few indigenous music practitioners still alive were on the brink of death, and there was therefore a need to capture the heritage before it was irretrievably lost. Lately the world of indigenous African music has undergone an evolution. South Africa’s rapidly changing postcolonial terrain has recently witnessed an upsurge of new stylistic trajectories  in  indigenous  musical  practices  –  nowadays  it  is  arranged  and performed by modern musical ensembles. Popular music which incorporates traditional genres has begun functioning within the socio-cultural and religious lives of Africans today, and it is no longer regarded as ‘foreign’ or alien to concert halls. It is now also frequently encountered in music stores, both in rural and urban areas. the current article traces this new, exciting and rewarding trajectory.

Over the last years, the economic and social structure of enterprises has undergone some important changes, especially because of the introduction of Information and Communication Technologies (ICTs). ICT is one of the fundamental elements driving the innovation and competitiveness of business activities which greatly influences the development of rural areas, both in economic and social terms. This publication focuses on the analysis and evaluation of the use of ICTs by enterprises in the Lubelskie Voivodeship with particular emphasis on rural areas. In the publication the authors use statistical analyses based on information from surveys conducted among entrepreneurs by the Marshal Office of the Lubelskie Voivodeship. The paper evaluates the following issues: the degree of computerisation of the company, the use of information technology in the company, the activity of the company on the Internet. The main objective of this study is to identify the relationship between the degree of computerisation and the company's innovation-oriented activities and to identify differences between companies located in urban and rural areas. The studies carried out have demonstrated that the differences in the computerisation of enterprises located in rural and urban areas are negligible and that there is a close relationship between the degree of computerisation and innovation in enterprises located in rural areas.

This paper aims to reflect an effort to identify the problems associated with the educational learning process, as well as its function to express some inherent considerations to the most effective forms of the classroom management. Mentioned in this discussion are ways of management for various categories of students, not only from an intellectual level, but also by their behavior. Also, in the elaboration of this theme I was considering that in addition to other development directions of the country, an important place is occupied by the education of the younger generation in our school environments and especially in adopting the methods of teaching and learning management with a view to enable this generation to be competitive in the European labor market. This, of course, can be achieved by giving this generation the best values of behavior, cultural level, professional level and ethics one of an European family which we belong to, not just geographically. On such foundations, we have tried to develop this study, always improving the reality of the prolonged transition in the field of children’s education. Likewise, we have considered the factors that have left their mark on the structure, cultural level and general education level of children, such as high demographic turnover associated with migration from rural and urban areas, in the capacity of our educational institutions to cope with new situations etc. In the conclusions of this study is shown that there is required a substantial reform even in the pro-university educational system to ensure a significant improvement in the behavior of children, relations between them and the sound quality of their preparation. Used literature for this purpose has not been lacking, due to the fact that such problems are usually treated by different scholars. Likewise, we found it appropriate to use the ideas and issues discussed by the foreign literature that deals directly with classroom management problems. All the following treatise is intended to reflect the way of an effective classroom management.
