Value creation in the international public procurement market: In search of springbok firms
2019
Abstract Public procurement accounts for more than 10% of global GDP. Digital transformation of public procurement creates new opportunities for value creation in international markets. Identifying and analyzing the companies, especially the SMEs, that can capitalize on these opportunities is therefore an important issue for policymaking, management, and scientific research. This study linked microdata on selected bidders from the Tenders Electronic Daily (TED) e-procurement portal and the Orbis database. Based on a sample of 933 Spanish companies, the analysis provides empirical support for the cross-border size bias conjecture. The reason for this bias is the predominance of large compani…
Desarrollo vocacional y preparación para la carrera profesional en estudiantes universitarios
2014
Abstract.VOCATIONAL DEVELOPMENT AND PREPARATION FOR CAREER IN COLLEGE STUDENTSPreparation for career emerges as a variable of interest in the university environment to the extent that these students pursue primarily their integration in the workplace for being formed. Moreover, the research reveals the importance of career development at the time of satisfaction and achievement in getting decisions made ??. Both variables are configured as highlights in the processes of counseling and vocational and career guidance. The aim of this study was to establish the relationship between preparation for career and vocational development considering gender as covariates and vocational group membershi…
Data granularity in mid-year life table construction
2020
[EN] Life tables have a substantial influence on both public pension systems and life insurance policies. National statistical agencies construct life tables from death rate estimates (𝑚���𝑥���), or death probabilities (𝑞���𝑥��� ), after applying various hypotheses to the aggregated figures of demographic events (deaths, migrations and births). The use of big data has become extensive across many disciplines, including population statistics. We take advantage of this fact to create new (more unrestricted) mortality estimators within the family of period-based estimators, in particular, when the exposed-to-risk population is computed through mid-year population estimates. We use actual d…
The Impact of the Direct Participation of Workers on the Rates of Absenteeism in the Spanish Labor Environment.
2020
The aim of this research was to study the relationship between the different levels of direct participation of workers (passive, consultative or active-delegated) in risk prevention management with the levels of absenteeism in Spain. To this end, a transversal study was carried out using microdata from the Second European Survey of Companies on New and Emerging Risks (ESENER-2-Spain, 2014) with a master population of 3162 work centres. A multinomial logistic regression model was carried out, with the dependent variable being the levels of absenteeism and the independent variables, the participation indicators and preventive management, calculating the adjusted odds ratio (aOR) between all t…

Suoli d'Italia: minacce, stato ed efficacia delle risposte
2011
La degradazione del suolo è uno degli aspetti più rilevanti del cambiamento globale e la vulnerabilità dei terreni italiani ai processi di degradazione è certamente superiore ad altri paesi europei, a causa delle caratteristiche specifiche e dell’ alta variabilità delle condizioni ambientali.Oltre alle cause naturali, la degradazione del suolo è spesso causata dall'effetto delle attività umane ed in particolare all'utilizzazione delle terre non corretta. Le informazioni memorizzate nella base di dati nazionale del suolo sono state usate per un primo controllo della qualità dei suoli italiani e degli effetti delle politiche gestionali. La banca dati è costituita da un database, contenente in…
Shape analysis for image retrieval
1994
The main aim of this paper is to describe a method for locating a subimage of a stored image that approximately matches a given query image. This matching can support naive users in accessing an image database according to image contents rather symbolic attributes. The query image can be either composed using painting tools or cuts out of an actual scanned image. Our method is based on the extraction of features from the query image and from the stored images. The following three steps are involved: (l) an ISODATA algorithm is applied to segment (into region) both the query image and the stored images; (2) the normalized moment and geometrica! features are computed from the segmented region…
Selection of Large Sub-Samples from the Continuous Sample of Working Lives Representative of the Benefits Provided by the Spanish Public Pension Syst…
2016
The Continuous Sample of Working Lives (CSWL) is a set of anonymized microdata with information about individuals taken from Spanish Social Security records. It provides very valuable information, which is used in many studies on labor economics and in the analysis of the Spanish public pension system. This article presents two major contributions: The first is an analysis of how representative CSWL is of the population of pensioners for the period 2005-2013. It is concluded that the CSWL does not follow the same distribution as the population with respect to some types of benefits, and that this happens in most waves. One of the reasons is that it is obtained by simple random sampling, so …
Incorporating big microdata in life table construction: A hypothesis-free estimator
2019
Abstract The IT revolution, now more than ever, offers a cheaper and faster way to collect, store, transmit and process data. Detailed microdata of dates of death, migration and birth are already becoming available for general populations. In this paper, we develop within the family of period-based estimators a new, assumption-free estimator for constructing life tables. The estimator proposed exploits all the detailed data available and is free of the theoretical inconsistencies that the estimators currently used by most official statistical agencies have. We compute the proposed estimator for a real database and test the suitability of the hypotheses on which the estimators used so far re…
Assessing implicit hypotheses in life table construction
2016
AbstractMortality figures are of capital importance for policy-making and public planning, as in forecasting financial provisions in public pension systems. General population life tables are constructed from aggregated statistics, an issue that usually entails adopting some (implicit) assumptions in their construction, such as the hypothesis of closed demographic system or the hypotheses of uniform distributions of death counts (and migration events) by age and calendar year. As microdata have become more abundant and reliable, these hypotheses could be assessed and more assumption-free estimators employed. Using a real database from Spain, we show that the above hypotheses are not appropr…
