A Web Application for Interactive Visualization of European Basketball Data
2020
The statistical analysis of basketball games is a fast-growing field. Certainly, basketball data are scientifically relevant because an appropriate analysis provides a great deal of information about the performance of both players and teams. The number of games played each season generates a large amount of data worth analyzing. Basketball analytics is well established in U.S. leagues. In Europe, however, it has not been duly developed. This study focuses on the top three European team competitions: the EuroLeague, the EuroCup, and the Spanish ACB (Association of Basketball Clubs, acronym in Spanish) league. Their official websites provide access to game data for anyone who is interested, …
Experiences from global e-collaboration: Contextual influences on technology adoption and use
2005
The article presents a cross-case comparison of experiences from organizational adoption and use of e-collaboration technologies in two large global companies. Challenges in the global implementation process were found to increase with the organizational and geographical scope of the implementation, level of autonomy in the adoption process, cultural diversity, technological heterogeneity, and level of work process support embedded in the system. Alignment with existing collaborative work practices resulted in faster adoption of the technological solution. Highly competitive conditions restricted the resources available for training and experience transfer between projects. Clients’ prefere…
Spark ignition feedback control by means of combustion phase indicators on steady and transient operation
2014
In order to reduce fuel cost and CO2 emissions, modern spark ignition (SI) engines need to lower as much as possible fuel consumption. A crucial factor for efficiency improvement is represented by the combustion phase, which in an SI engine is controlled acting on the spark advance. This fundamental engine parameter is currently controlled in an open-loop by means of maps stored in the electronic control unit (ECU) memory: such kind of control, however, does not allow running the engine always at its best performance, since optimal combustion phase depends on many variables, like ambient conditions, fuel quality, engine aging, and wear, etc. A better choice would be represented by a closed-…
The Role of Artificial Intelligence in Social Media Big data Analytics for Disaster Management -Initial Results of a Systematic Literature Review
2018
When any kind of disaster occurs, victims who are directly and indirectly affected by the disaster often post vast amount of data (e.g., images, text, speech, video) using numerous social media platforms. This is because social media has recently become a primary communication channel among people to report either to public or to emergency responders (ERs). ERs, who are from various emergency response organizations (EROs), usually consider to gain awareness of the situation in order to respond to occurred disaster. However, with the occurrence of the disaster, within minutes, the social media platforms are flooded with various kinds of data which become overwhelmed for ERs with big data. Fu…
How do organizational processes recover following a disaster? - A capital resiliency model for disaster preparedness -
2016
This paper explores how organizational processes are recreated following their destruction in unexpected disasters. It applies the notion of an organization as a capital conversion and capital creation system. It also focuses on systems resilience, the measure of a system's persistence and ability to absorb disturbances while reconstructing relationships between system entities. Based on the analysis of empirical evidence collected from the Great East Japan Earthquake disaster in 2011, we propose a resiliency model incorporating a broader interpretation of the notion of capital. The model consists of five dimensions of capital: economic, social, symbolic, human, and organizational. Once a g…
An Exploratory Case Study of Offshore Outsourcing: Problems in Multicultural Settings
2014
Outsourcing means using factors which are external to an organization to perform its functions whereas offshore outsourcing relies on using foreign resources to perform those functions. We focus in this paper on offshore outsourcing of information systems (ISs). We have conducted an exploratory case study of outsourcing IS support services. The services have been outsourced by a supplier organization which has been based in Finland. Main parts of its customer support services have been allocated to so-called production centers, which have been located in three countries; Latvia, India, and the Philippines. We have gathered qualitative data from nine experts via theme-based interviews. The e…

Using results companies will be able to share their customers seeing at what stage they are loca…
Corporate e-Governance Disclosure in the Digital Age: An Empirical Study of Spanish Listed Companies
2005
Corporate governance research has focused mainly on the analysis of the information that firms ought to disclose and the effects of disclosure, basically without considering the media involved. This paper examines the relevance of technology, and particularly the internet, for the improvement of corporate governance and transparency in listed companies. The need for this study is clear in view of the increasing interest shown by supervisory authorities for the oversight of the European and US capital markets in regulating not only content but also the manner in which corporate governance information is disclosed over the internet. In this paper we have quantified three corporate governance …
Knowledge creation. The ongoing search for strategic renewal
2014
Purpose– The purpose of this paper is to analyse how changes in a set of structural design variables (i.e. liaison position, networked design, innovation teams and work teams) affect the creation of new knowledge within organizations. The enablers intention, autonomy, fluctuation and creative chaos, redundancy, variety, and trust and commitment, taken from Nonaka's framework, are used as intermediate variables.Design/methodology/approach– A sample of 167 large Spanish companies was used to empirically test a general relational model.Findings– The analysis yielded two main conclusions. First, the relationship between structural variables and enablers, and, second, the relationship of enabler…
A study on forecasting electricity production and consumption in smart cities and factories
2019
Abstract The electrical power sector must undergo a thorough metamorphosis to achieve the ambitious targets in greenhouse gas reduction set forth in the Paris Agreement of 2015. Reducing uncertainty about demand and, in case of renewable electricity generation, supply is important for the determination of spot electricity prices. In this work we propose and evaluate a context-based technique to anticipate the electricity production and consumption in buildings. We focus on a household with photovoltaics and energy storage system. We analyze the efficiency of Markov chains, stride predictors and also their combination into a hybrid predictor in modelling the evolution of electricity producti…
