Modeling ontologies for robotic environments
2002
On the basis of a multiple abstraction levels specification process, we developed a representational model for environmental robotic knowledge through the definition of a set of ontologies using a multi perspective approach. A general ontological model for typical indoor environments has been first developed, followed by its specialization using an implementation perspective. Actual software implementation of the ontology has been obtained via a XML-based markup language, used to build a repository for robotic environmental knowledge. Copyright 2002 ACM.
N,N-Dimethyl-N-propylpropan-1-aminium chloride monohydrate
2008
The title compound, C8H20N+·Cl−·H2O, has been prepared by a simple one-pot synthesis route followed by anion exchange using resin. In the crystal structure, the cations are packed in such a way that channels exist parallel to the b axis. These channels are filled by the anions and water molecules, which interact via O—H...Cl hydrogen bonds [O...Cl = 3.285 (3) and 3.239 (3) Å] to form helical chains. The cations are involved in weak intermolecular C—H...Cl and C—H...O hydrogen bonds. The title compound is not isomorphous with the bromo or iodo analogues.
Study of the Strengths and Weaknesses of Nursing Work Environments in Primary Care in Spain
2021
Background: Nursing work environments are defined as the characteristics of the workplace that promote or hinder the provision of professional care by nurses. Positive work environments lead to better health outcomes. Our study aims to identify the strengths and weaknesses of primary health care settings in Spain. Methods: Cross-sectional study carried out from 2018 to 2019. We used the Practice Environment Scale of the Nursing Work Index and the TOP10 Questionnaire of Assessment of Environments in Primary Health Care for data collection. The associations between sociodemographic and professional variables were analyzed. Results: In total, 702 primary care nurses participated in the study. …

Indeksy i bazy danych jako źródła w studiach nad bezpieczeństwem. Stan badań
2021
Artykuł przedstawia metaanalizę w zakresie użyteczności narzędzi poznawczych w studiach nad bezpieczeństwem narodowym i międzynarodowym, jakimi są indeksy, rankingi i bazy danych. Ich użycie w studiach społecznych sięga czasów behawioralizmu oraz projektów takich jak Korelaty Wojny (Correlates of War, CoW), czy coroczne raporty takich instytucji jak PRIO, SIPRI, czy IISS. Rozwój organizacji międzynarodowych i narzędzi analitycznych zwiększył możliwości pozyskiwania danych ilościowych i jakościowych na temat zbrojeń, konfliktów, wojen, a także poczucia bezpieczeństwa, percepcji zagrożeń, jakości życia, czy zdrowia etc. W tekście analizuję kilkadziesiąt indeksów, rankingów i baz danych (datas…
On the Sampling Size for Inverse Sampling
2022
In the Big Data era, sampling remains a central theme. This paper investigates the characteristics of inverse sampling on two different datasets (real and simulated) to determine when big data become too small for inverse sampling to be used and to examine the impact of the sampling rate of the subsamples. We find that the method, using the appropriate subsample size for both the mean and proportion parameters, performs well with a smaller dataset than big data through the simulation study and real-data application. Different settings related to the selection bias severity are considered during the simulation study and real application.
Staging and storing data sprint-based research results: a communication design approach
2022
Data sprints are multidisciplinary, time-limited, practice-oriented, and group activities that explore complex issues through data gathering, visualization, and analysis. Data sprints usually conclude with final presentations where participants showcase the research process they followed and the achieved results. Although this activity is now widespread in some research centers, there does not appear to be a data-sprint tailored dissemination format that can support the organization, archive, and online diffusion of results. Starting from the experience of a data sprint on Digital Methods, the paper describes the design process of a digital format which condenses and reinterprets good pract…
