Is students’ teamwork a dreamwork? A new DCE-based multidimensional approach to preferences towards group work
No full textThe data refer to the study on the preferences of lower secondary school students in Poland for different modes of learning and school subjects. It employs a discrete choice experiment to describe student preferences in light of the time devoted to studying. The study shows significant heterogeneity of student tastes for different study modes. Most students prefer studying in a group of peers, but there are important differences across students at different achievement levels and subjects. This study demonstrates how preferences toward learning can be properly measured using discrete choice experiments.Data related to publication: Gajderowicz, T., Jakubowski, M., Wrona, S. et al.

Formal Modelling of Content-Based Protection and Release for Access Control in NATO Operations
No full textThe successful operation of NATO missions requires the effective and secure sharing of information among coalition partners and external organizations, while avoiding the disclosure of sensitive information to unauthorized users. To resolve the conflict between confidentiality and availability in a dynamic coalition and network environment while being able to dynamically respond to changes in protection requirements and release conditions, NATO is developing a new information sharing infrastructure. In this paper we present the Content-based Protection and Release (CPR) access control model for the NATO information sharing infrastructure. We define a declarative specification language for CPR based on the first-order logical framework underlying a class of efficient theorem-proving tools, called Satisfiability Modulo Theories solvers, and describe how they can support answering authorization queries. We illustrate the ideas in a use case scenario drawn from the NATO Passive Missile Defence system for simulating the consequences of intercepting missile attacks
Impact of virtual reality applications in the treatment of anxiety disorders: A systematic review and meta-analysis of randomized-controlled trials
No full textSchröder D, Wrona KJ, Müller F, Heinemann S, Fischer F, Dockweiler C. Impact of virtual reality applications in the treatment of anxiety disorders: A systematic review and meta-analysis of randomized-controlled trials. Journal of Behavior Therapy and Experimental Psychiatry . 2023;81: 101893.BACKGROUND AND OBJECTIVES: Anxiety disorders are the most prevalent mental disorders worldwide. Virtual reality (VR) treatment approaches have increasingly been studied. Before clinical implementation, it is necessary to evaluate the treatment effect of VR applications. The objective is to evaluate the treatment effect of virtual reality applications in the treatment of anxiety disorders compared to conventional therapy.; METHODS: A systematic literature review with meta-analysis was conducted. Four databases were used to identify randomized controlled trials published between April 2011 and April 2021 which compare VR applications with non-VR interventions or waiting lists. Study characteristics, pre- and post-treatment data were extracted. Hedges g was calculated as effect size. Primary outcome was anxiety symptoms.; RESULTS: Data from 17 studies from 827 participants was extracted. The studies examined specific phobia (n=9), social anxiety disorder (n=4), agoraphobia (n=2) and panic disorder (n=2). 16 out of 17 studies used head-mounted displays as VR application. A non-significant effect size with significant heterogeneity was observed in favor of the use of VR applications in anxiety symptoms (g, 0.33; 95%-CI, -0.20-0.87). Compared to passive control groups, VR applications are associated significant with lower anxiety symptoms (g, 1.29; 95%-CI, 0.68-1.90).; LIMITATIONS: The study and patient characteristics varied between the individual studies which is reflected in a high statistical heterogeneity of the effect sizes.; CONCLUSIONS: The added value of VR applications over waiting-list or psychoeducation only control groups is obvious. VR applications can be used as part of the treatment of anxiety disorders, especially when conventional therapy is unavailable. Copyright © 2023 The Authors. Published by Elsevier Ltd..

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Precise Orbit Determination on LEO Satellite using Pseudorange and Pseudorange-Rate Measurements
No full textNowadays, along with the trend of developing highly autonomous satellites, there is a strong motivation to improve real-time Precise Orbit Determination (POD), in particular for Low Earth Orbit (LEO) satellites. The development of Global Navigation Satellite System (GNSS) sensors allows to obtain low-noise measurements and provide a satellite with autonomous continuous tracking onboard. Following the deactivation of Selective Availability, a representative real-time positioning accuracy of 10 m is presently achieved by means of Global Positioning System (GPS) receivers on LEO satellites. The introduction of dynamical filtering methods has opened a new way to improve this accuracy by making use of measurements such as pseudorange or carrier-phase. This paper presents a Kalman filtering approach using pseudorange and pseudorange-rate measurements instead of pseudorange and carrier-phase ones, with advantages in terms of storage and processing requirements. An error of around 0.2 m and 1e-3 m/s for position and velocity is obtained, which is in line if not better w.r.t. other approaches

No full textCan archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
