A Cluster Analysis Approach to Profile Men and Women’s Volley Positions in Professional Tennis Matches (Doubles)
2021
(1) Background: Tennis ball tracking technology allows the aquirement of novel and reliable data about several performance indicators, such as volley positions. This information is key to understand match dynamics in doubles tennis and to better help preparing players for the demands they will face in match play. As such, the purpose of this study was to describe and compare the different types of volley positions in men’s and women’s doubles professional tennis. (2) Methods: Ball tracking data were collected for 46 women (Billie Jean King Cup) and 96 men’s doubles matches (Davis Cup). The variables used were the distance to the net, the distance to the centre of the court and the height of…
La destrucció del patrimoni artístic i la seua reconstrucció. Un exercici de microhistòria: el cas de Llíria i la Confraria de la Sang (1936-1949)
2020
The problem of artistic destruction and its reconstruction has been little studied. Using a microhistorical analysis method, we study the town of Lliria (Valencia) and its brotherhood of ?La Sang de Jesucrist? (had a great heritage from the 16th to the 19th centuries), and we also analyze how and why this destruction and reconstruction was generated during the context of the civil war. We use and combine different sources (public of the ?Causa General? and private of the ?Minute Books?) for this research, with the intention of specifying the analysis of this complex process. We also explain social and artistic relationships of these two processes, that help us study the workshops of the mos…
Violência, evasão e exclusão na educação superior
2019
The present text focuses on a relationship between higher education, institutional and symbolic violence and exclusion, practicing as a challenge based on reflections on the existence of evasion in Brazilian university. Ignoring the educational institution as a direct responsible for these things, this text considers that a logic in University organization and operation helps to enlarge inequalities that provide the mechanisms of evasion; at the same time, it presents itself as a space of reference and a struggle against social inequalities and violence. On a provisional basis, the text stands out that: depending on the execution of educational procedures and practices undertaken by the ins…
Information, Communications and Media Technologies for Sustainability: Constructing Data-Driven Policy Narratives
2021
This paper introduces the idea of data-driven narratives to examine how the use of information, communications, and media technologies (ICMTs) impacts the sustainable growth of economies. While ICMTs have regularly been advocated as a policy tool for growth and development, there is a research gap in empirical studies validating how such policies may be effective. This analysis is based on historical panel data from 39 economies across the developed North (19) and developing South (20). The industry-standard Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology was applied to construct narratives that weave extant theories with empirical data. The art of developing data-dri…
Configurational theory in traditional manufacturing industries: a new model of high-performing small and medium-sized enterprises
2020
The goal of this study is to provide a model of high-performing small and medium-sized companies to address the new environmental challenges in traditional manufacturing industries. Adopting a configurational logic and following an inductive approach based on four high-performing firms, this paper provides new empirical evidence on how the steps followed by these firms are adjusted to the high-performance models prescribed by the literature. In doing so, it also offers a dynamic view of the interrelationships between the strategy and the new conditions of the environment. At a practitioner level, the paper illustrates which recipes are more appropriate to prescribe recommendations for a mor…
Use of information sources in outbound travel planning: case of the Netherlands and Belgium
2020
In the Information Age travellers have a wide range of information that can be accessed by a variety of channels. The kind of information search travellers undertake and acquire will have significant consequences for the purchases they will make. There is a need for repeated studies to track possible changes in tourist behaviour for information search patterns as use of information sources and their combination evolve over the time. Understanding tourists’ information search peculiarities can be of use for tourism scholars and practitioners in the marketing planning process. Majority of European citizens are travelling mainly within their home country (Eurobarometer, 2014) still small count…
The nexus between big data and sustainability: an analysis of current trends and developments
2021
[EN] With the development of technological innovations, Big Data is transforming the socioeconomic world, impacting almost every organization and person. The transformations associated with the development of Big Data have important consequences for the sustainability of organizations, regions, and the society as a whole, and as such, they have been specifically addressed by the academic literature focusing on sustainability. Despite its importance, and perhaps because of its rapid emergence, there is a lack of studies dealing with the analysis of this body of literature and its trends. The current research attempts to fill this gap. The study develops a bibliometric and visualization analy…
Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …
Electrooxidation of diesel fuel in alkaline electrolyte
2016
In recent decades the demand of energy has increased significantly.Providing more and more energy is an essential task of today’s energetic industry. In the last few years, addition to traditional methods of energy production, alternative energy sources have been developing fast.One of these sources is fuel cell, mainly due to their high efficiency. Generally fuel cells are powered by hydrogen. However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. Moreover, fuel cells can provide an additional/emergency electricity source in energy systems using combustion engines. So, it is important using the main fuel for powering the fuel cell. One of …
Pathways for the amplification of agroecology in African sustainable urban agriculture
2020
A growing awareness that highly intensified agricultural systems have made a substantial worldwide contribution to the worsening of the resilience capacity of natural ecosystems has, over the last twenty years, brought general attention to agroecological management models. This aspect is even more evident in industrial agriculture, which is based on the use of multiple chemical products derived from non-natural synthesis. In more developed countries, a new idea of ecology linked to agricultural production has been increasingly developed and, for this reason, there has been a greater diffusion of differentiated agricultural models taking into consideration the environmental impact of product…
