Alternative Income Sources – Entrepreneurship Development or Households’ Economic Needs after the COVID-19 Crisis?

2021

Purpose: The purpose of this paper is to identify and analyze the COVID-19 pandemic implications for alternative income sources in transition economy with the dispute based on literature and research. Design/Methodology/Approach: The following research methods were used. Desk extensive research and analysis of raw data collected for the study. An original in-depth interview form was developed, and scientific dispute based on subject literature was conducted. A research hypothesis, aimed at verifying the research problem, were formulated. Findings: The study highlights that, aside from passion, the main reason for undertaking additional economic activity is to obtain additional income. Pract…

Using Wavelet Techniques to Approximate the Subjacent Risk of Death

2018

In Actuarial science, graduation techniques have been used extensively: the large number of scientific papers and technical documentation published evidences this fact (see Ayuso M et al. (Estadistica Actuarial Vida. UBe, Barcelona (2007)), Baeza Sampere and Morillas Jurado (Rev. Anales del Instituto de Actuarios Espanoles 135–164 (2011)), London (Graduation: The Revision of Estimates. ACTEX Publications, Connecticut (1985)), Cairns, et al. (Scand Actuar J 2(3):79–113 (2008)) and the references therein). Graduation techniques are defined by Haberman and Renshaw J Inst Actuar 110:135–156 (1983) as a set of principles and techniques for use that are used on raw data so that a more appropriate…

Statistically validated mobile communication networks: the evolution of motifs in European and Chinese data

2014

Big data open up unprecedented opportunities to investigate complex systems including the society. In particular, communication data serve as major sources for computational social sciences but they have to be cleaned and filtered as they may contain spurious information due to recording errors as well as interactions, like commercial and marketing activities, not directly related to the social network. The network constructed from communication data can only be considered as a proxy for the network of social relationships. Here we apply a systematic method, based on multiple hypothesis testing, to statistically validate the links and then construct the corresponding Bonferroni network, gen…

The availability of raw data in substance abuse scientific journals

2018

[Objective]: The availability of research data sets is an important milestone since it can enhance the dynamics of research. This study aims to analyse the PubMed Central repository to determine the availability and type of raw data sets in Substance Abuse journals indexed in the Journal Citation Reports.

Title: The Emergency Medicine Facing the Challenge of Open Science

2020

This article belongs to the Special Issue Data Reuse for Sustainable Development Goals.

2020

Background E-science technologies have significantly increased the availability of data. Research grant providers such as the European Union increasingly require open access publishing of research results and data. However, despite its significance to research, the adoption rate of open data technology remains low across all disciplines, especially in Europe where research has primarily focused on technical solutions (such as Zenodo or the Open Science Framework) or considered only parts of the issue. Methods and findings In this study, we emphasized the non-technical factors perceived value and uncertainty factors in the context of academia, which impact researchers' acceptance of open dat…

Legri Science Operation Center. Architecture and Operations

2001

The LEGRI Science Operation Center (SOC) is the single contact point between the MINISAT-01 Centro de Operaciones Cientificas (COC) located at Villafranca del Castillo (Madrid) and the LEGRI Consortium. Its architecture, operational procedures and associated software has been developed at the Universities of Valencia and Birmingham on the scope to define a integrated Data Analysis System, able to perform the daily follow-up of the instrument health, raw data files decompression and archiving activities (on-line and historical). Pointing and telecommand files generation are also SOC responsibilities. The aim of this paper is to report the SOC activities during the two years of LEGRI operatio…

Modeling recurrent distributions in streams using possible worlds

2015

Discovering changes in the data distribution of streams and discovering recurrent data distributions are challenging problems in data mining and machine learning. Both have received a lot of attention in the context of classification. With the ever increasing growth of data, however, there is a high demand of compact and universal representations of data streams that enable the user to analyze current as well as historic data without having access to the raw data. To make a first step towards this direction, we propose a condensed representation that captures the various — possibly recurrent — data distributions of the stream by extending the notion of possible worlds. The representation en…

OpenTIMS, TimsPy, and TimsR: Open and Easy Access to timsTOF Raw Data

2021

The Bruker timsTOF Pro is an instrument that couples trapped ion mobility spectrometry (TIMS) to high-resolution time-of-flight (TOF) mass spectrometry (MS). For proteomics, lipidomics, and metabolomics applications, the instrument is typically interfaced with a liquid chromatography (LC) system. The resulting LC-TIMS-MS data sets are, in general, several gigabytes in size and are stored in the proprietary Bruker Tims data format (TDF). The raw data can be accessed using proprietary binaries in C, C++, and Python on Windows and Linux operating systems. Here we introduce a suite of computer programs for data accession, including OpenTIMS, TimsR, and TimsPy. OpenTIMS is a C++ library capable …
