A Method for Designing Tools for Information Retrieval from Documents
1987
The paper describes an experimental document database language. It consists of document database extensions to Prolog. An extended Prolog is suitable for specifying, prototyping, and in some cases also for implementing information retrieval tools.
The global impact of the COVID-19 pandemic on the management and course of chronic urticaria
2021
Introduction: the COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown. Aim: to understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19. Materials and methods: our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences. Results: the COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers o…
A new definition of soil to promote soil awareness, sustainability, security and governance
2022
Abstract In these last decades, the awareness that soil is a very important resource for humans has noticeably increased. Many actions and initiatives to promote soil governance, aiming at sustainable soil management and soil security have been undertaken by several national and international institutions and in many countries. Analysis of the changes of soil perception over the centuries allows highlighting a perfect harmony between the evolution of soil awareness and the level of knowledge and technology achieved by humans during their history and evolution. Notwithstanding these many achievements, soils continue to be scarcely considered in politics and society. We suggest some thoughts …
Controversies on the origin of life
2005
Different viewpoints, many with deep philosophical and historical roots, have shaped the scientific study of the origin of life. Some of these argue that primeval life was based on simple anaerobic microorganisms able to use a wide inventory of abiotic organic materials (i.e. a heterotrophic origin), whereas others invoke a more sophisticated organization, one that thrived on simple inorganic molecules (i.e. an autotrophic origin). While many scientists assume that life started as a self-replicative molecule, the first gene, a primitive self-catalytic metabolic network has also been proposed as a starting point. Even the emergence of the cell itself is a contentious issue: did boundaries an…
High-definition transcranial direct current stimulation to both primary motor cortices improves unimanual and bimanual dexterity.
2017
While most research on brain stimulation with transcranial direct current stimulation (tDCS) targets unimanual motor tasks, little is known about its effects on bimanual motor performance. This study aims to investigate the effects of tDCS on unimanual as well as bimanual motor dexterity. We examined the effects of bihemispheric anodal high-definition tDCS (HD-atDCS) on both primary motor cortices (M1) applied concurrent with unimanual and bimanual motor training. We then measured the effects with the Purdue Pegboard Test (PPT) and compared them to a sham stimulation. Between a pretest and posttest, 31 healthy, right-handed participants practiced the PPT on three consecutive days and receiv…
GAIML: A New Language for Verbal and Graphical Interaction in Chatbots
2008
Natural and intuitive interaction between users and complex systems is a crucial research topic in human-computer interaction. A major direction is the definition and implementation of systems with natural language understanding capabilities. The interaction in natural language is often performed by means of systems called chatbots. A chatbot is a conversational agent with a proper knowledge base able to interact with users. Chatbots appearance can be very sophisticated with 3D avatars and speech processing modules. However the interaction between the system and the user is only performed through textual areas for inputs and replies. An interaction able to add to natural language also graph…

Operational Definition of Serious Mental Illness: Heterogeneity in a Review of the Research on Quality-of-Life Interventions
2020
BACKGROUND: An operational definition of serious mental illness (SMI) with well-defined inclusion criteria allows the identification of the most vulnerable individuals and secures resources to meet their needs and develop social programs for their treatment, rehabilitation, and recovery. In addition, the contents of a clinical construct such as SMI have an impact on both the development and the clinical application of the research results. However, currently, different ways of operationalizing the definition of SMI coexist. AIMS: The aim of this review was to explore whether unanimity exists in the operationalization of SMI definitions in quality-of-life interventions research. METHODS: A r…
Improving the Effect of Transcranial Alternating Current Stimulation (tACS): A Systematic Review
2021
With the development of electrical stimulation technology, traditional transcranial alternating current stimulation (tACS) technology has been found to have the drawback of not targeting a specific area accurately. Studies have shown that optimizing the number and position of electrodes during electrical stimulation has a very good effect on enhancing brain stimulation accuracy. At present, an increasing number of laboratories have begun to optimize tACS. However, there has been no study summarizing the optimization methods of tACS. Determining whether different optimization methods are effective and the optimization approach could provide information that could guide future tACS research. …
Conceptualising Violence in Close Relationships : Discrepancies Between Police Conceptions and the Letter of the Law in Finland
2020
AbstractThe focus in this Finland-based study is on violence in close relationships—a term that partly overlaps with the more commonly used ‘domestic violence’, ‘family violence’ and ‘intimate partner violence’. We demonstrate how police officers’ conceptualisations of such violence differ from how it is defined in relevant legal documents. The data consists of the Government Bill and legal text on the subject issued as part of a legal reform enacted in 2010, and of a qualitative sample of freelist responses from 79 police officers. We examined both sets of data using theory-driven directed content analysis and deriving from prevailing theoretical frameworks reflecting the family- and gende…
