GPU-Based Occlusion Minimisation for Optimal Placement of Multiple 3D Cameras
2020
This paper presents a fast GPU-based solution to the 3D occlusion detection problem and the 3D camera placement optimisation problem. Occlusion detection is incorporated into the optimisation problem to return near-optimal positions for 3D cameras in environments containing occluding objects, which maximises the volume that is visible to the cameras. In addition, the authors’ previous work on 3D sensor placement optimisation is extended to include a model for a pyramid-shaped viewing frustum and to take the camera’s pose into account when computing the optimal position.
Peer Group Mentoring Programmes in Finnish Higher Education––Mentors’ Perspectives
2014
Peer mentoring is one of the most important guidance practices for first-year students entering higher education and academic life. We are interested in mentors’ roles and apply the ideas of group counseling in order to increase the understanding of peer mentoring. Other aspects of guidance––content, methods, and collaboration––are approached on the basis of the holistic career guidance model. The data were gathered via an online questionnaire (n = 784) from 20 Finnish HE institutions. The results show that peer mentoring is a positive experience. The main emphasis is on the personal, psychosocial aspects of the student’s life. We identified four mentor types based on used activities. The e…
How is motivational interviewing (un)related to self-determination theory: An empirical study from different healthcare settings.
2021
To explore how quality aspects and clients’ verbal behaviors in Motivational Interviewing sessions correspond with counsellors’ support of basic psychological needs described in Self-determination Theory, we conducted a mixed method study with quantitative analyses of transformed qualitative data from counselling sessions. Coding manuals identified if the counselling was consistent with Motivational Interviewing and the support of basic psychological needs. The study supported a conceptual relationship between motivational interviewing (MI) and self-determination theory (SDT), except for autonomy support which was conceptualized differently in the two approaches. Relational support in SDT a…
Exploring the mediator role of self-critical rumination between emotion regulation and psychopathology: A validation study of the Self-Critical Rumin…
2021
Abstract Self-critical rumination is a negative and repetitive self-thinking process related to different disorders and negative psychological outcomes such as emotion dysregulation. The objectives of this study are twofold: (a) to examine the factor structure of the Spanish version of the Self-Critical Rumination Scale (SCRS), providing further evidence on its construct validity, and (b), to explore the mediator role of self-critical rumination between emotion dysregulation and psychopathology. A sample of 431 Spanish participants were recruited and completed online questionnaires. Confirmatory factor analysis, mediation analysis, and Pearson's correlations were conducted. A single factor …
Dental emergency care in Spain during the state of alarm due to COVID-19 pandemic.
2020
Background: The first state of alarm due to COVID-19 in Spain led to limit dental treatment exclusively to emergencies. The objective of the survey was to evaluate the amount and type of emergencies attended during this period, as well as to know how they were solved, and what measures were adopted to carry out dental care in these exceptional circumstances. Material and Methods: This cross-sectional study included 312 Spanish dentists, who fulfilled an online questionnaire with 22 closed questions, divided into five sections regarding to various aspects of professional dental profile and emergency care. Descriptive statistic and Chi-square tests were performed (p<0.05). Results: 75.64% of …
Beer produced via hydrodynamic cavitation retains higher amounts of xanthohumol and other hops prenylflavonoids
2017
Abstract Some of the most valuable bioactive compounds in beer comes from hops polyphenols, mainly flavonoids, some of which are unique to inflorescences of that flowering plant. Although far from pharmacologically relevant concentrations, low doses of xanthohumol and related prenylflavonoids found in beer contribute to the overall antioxidant activity of the product, as well as to significant chemopreventive action about certain diseases, such as cardiovascular, neurodegenerative, and some cancer types. Hence, the efforts to explore both ingredients and brewing methods aimed at enhancing the concentration of such bioactive compounds. In this study, a novel brewing method assisted by hydrod…
Information retrieval in digital documents : a variation patterns of procedural execution
2013
The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The “usual” condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are intereste…
Determinants affecting consumers' attention to fish eco-labels in purchase decisions: a cross-country study
2022
PurposeThe purpose of this study was to investigate the role of consumer altruism and other socio-cultural factors in predicting how much attention consumers pay to seafood eco-labels.Design/methodology/approachThe empirical investigation was carried out by administering an online questionnaire to a sample of Italian and Spanish people from December 2019 to April 2020. After carrying out the principal component analysis procedure, the work made use of an ordinal logistic regression.FindingsBoth Italian and Spanish consumers with an altruistic attitude, who feel that food produced in a sustainable way can protect the environment and workers, appear more likely to take an eco-label into accou…
Measuring consumers’ level of satisfaction for online food shopping during COVID-19 in Italy using POSETs
2021
Abstract The pandemic COVID 19 has upset the economic, social, financial, and general behavioral systems. Global crisis has a large impact overall and related fallouts significantly affect existent structural paradigms in every country and region across the world. In particular, the spread of COVID-19 pandemic has led to having to rethink the way we produce and consume food. Within this global change, a rise in the number of consumers who purchase food products online in order to comply with the rules aimed at limiting the circulation of the virus should be emphasized. Consequently, probably causing a long-term positive effect on m-commerce. The purpose is to elaborate on the index of the s…
Impact of students’ performance in the continuous assesment methodology through Moodle on the final exam
2017
[EN] This paper looks into the different evolution of students’ online questionnaire performance and its impact on the final examination mark. This innovative technique has been used in a group of an introductory financial accounting course with 8 online questionnaires (one per unit) in the Moodle platform. Using cluster analysis, we identify different groups of performance evolution. The evidence obtained suggests that in one of this groups a favourable test performance evolution may lead to overconfidence with the subsequent negative effect on the final examination mark. Future research with more variables and bigger samples will help identifying this student profile with a view to preven…
