Error messages in relational database management systems: A comparison of effectiveness, usefulness, and user confidence

2021

Abstract The database and the database management system (DBMS) are two of the main components of any information system. Structured Query Language (SQL) is the most popular query language for retrieving data from the database, as well as for many other data management tasks. During system development and maintenance, software developers use a considerable amount of time to interpret compiler error messages. The quality of these error messages has been demonstrated to affect software development effectiveness, and correctly formulating queries and fixing them when needed is an important task for many software developers. In this study, we set out to investigate how participants ( N = 152 ) …

Lidar detection of carbon dioxide in volcanic plumes

2015

Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…

Volcanic Plume CO2 Flux Measurements at Mount Etna by Mobile Differential Absorption Lidar

2017

Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO2) flux. Unfortunately, the traditional techniques used to measure volcanic CO2 require near-vent, in situ plume measurements that are potentially hazardous for operators and expose instruments to extreme conditions. To overcome these limitations, the project BRIDGE (BRIDging the gap between Gas Emissions and geophysical observations at active volcanoes) received funding from the European Research Council, with the objective to develop a new generation of volcanic gas sensing instruments, including a novel DIAL-Lidar (Differential Absorption Light Detection and Ranging) for remote (e.g., distal) …

Traces of the past: an interview study with Finnish war children who did not return to Finland after the Second World War

2017

ABSTRACTThis paper is an in-depth qualitative study based on interviews with 10 Finnish children who were evacuated to Sweden during Second World War and who did not return to Finland after the war. The interviewees were asked to tell about their lives. Nine of them were between 2 and 5 years and one was 7 years old at the time of evacuation. The aim was to study how their childhood experiences were reflected in adult memories, how they remembered or did not remember. This paper focuses on the consequences of not knowing about one’s early life and also on whether it is possible to observe signs of the Finnish mother. She did not appear explicitly but could be sensed in the tendency of the i…

Wyzwalanie dziecięcej aktywności matematycznej w trakcie rozwiązywania zadań

2018

Aktywność ucznia ma ogromne znaczenie w kształtowaniu i rozwijaniu abstrakcyjnych pojęć matematycznych. Jednak aktywność ta nie powinna ograniczać się jedynie do aktywności zewnętrznej, często jedynie pozornej, ale przede wszystkim powinna być to aktywność umysłowa ucznia. Zachowania i postawy specyficzne dla aktywności matematycznej można bowiem rozwijać u ucznia jedynie w toku jego aktywności poznawczej (intelektualnej). W opracowaniu podjęto próbę ukazania możliwości stymulowania i rozwijania oraz przejawy aktywności matematycznej uczniów w wieku wczesnoszkolnym w trakcie rozwiązywania zadań.

Relaxation of a weakly discontinuous functional depending on one control function

2008

The paper considers an optimal control problem of the typewhere the set M of admissible controls consists of all measurable vector‐functions h, which can take only two values h1 or h2. It is shown that the relaxation of this problem can be explicitly computed by rank‐one laminates.

The Effect of Emotional Dissonance and Mental Load on Need for Recovery and Work Engagement among Italian Fixed-Term Researchers

2020

Although many studies have been conducted to evaluate the risk and protective factors on psychological health among academic staff, little attention has been paid to fixed-term researchers, the weakest figures in the academic context. By using the Job Demands&ndash

Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry

2021

Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…
