This analytical position paper aims to open a discussion on the future of the naturalized technology of reading. Our analysis contributes to the discussion that we think scholars in human-computer interaction should adopt from other disciplines. We begin with a seven-level technology pyramid which ends with naturalized technology. We look for the place of paper and digital books in this pyramid, currently somewhere between invisible and vital technologies. We discuss scenarios for the book, using current theories of reading from both philosophical and neuropsychological viewpoints. Finally, we show inspiring quantitative and qualitative data gathered during „total research” into the literary culture. They illustrate the ongoing change in the reading ecosystem.

Równowaga między życiem zawodowym i osobistym wśród młodych naukowców w Polsce

Anna Knapińska, Monika Szyszko

2018 Humanizacja Pracy, T. 293, z. 3, s. 89-113

Głównym celem artykułu jest sprawdzenie, czy naukowcy do czterdziestego roku życia doświadczają równowagi pomiędzy pracą naukową

a życiem osobistym WLB (work-life balance) i czy w tym obszarze występują różnice między kobietami i mężczyznami. Przeprowadzone przez

nas na reprezentatywnej próbie naukowców w Polsce badanie pokazało, że młodzi naukowcy nie doświadczają równowagi praca-życie, przy czym na prawie każdym wskaźniku kobiety osiągnęły istotnie niższe wyniki od mężczyzn. Najniższy poziom WLB wystąpił u kobiet posiadających dzieci, co oznacza, że jest im najtrudniej zachować równowagę między karierą i rodziną. Analiza regresji w grupie matek wykazała, że na poczucie równowagi najsilniej wpływa konieczność rezygnacji ze spraw osobistych (negatywnie) oraz poczucie, że znalezienie nowej pracy będzie łatwe (pozytywnie). Uzyskane wyniki mogą w znaczący sposób poszerzyć wiedzę na temat work-life balance w świecie nauki

The article presents analysis of Polish Internet political discussion forums, characterized by significant polarization and high levels of emotion. The study compares samples of discussions gathered from the Internet comments concerning the last Polish election candidates. The authors compare three dictionary based sentiment analysis methods (built using different sentiment lexicons) with two machine learning ones, and explore methods using word embeddings to enhance sentiment analysis using dictionary based algorithms. The best performing algorithm is giving results closely corresponding to human evaluations.

Rising popularity of photovoltaic panels and other equipment allowing the electricity production in households evoke the new challenges – i.e. high energy exchange due to high production or usage peaks. One of the solution to such problems is the Energy Management System (EMS) which is able to monitor and report real-time power consumption. EMS allows for launching a whole range of new features – i.e. flexible tariffs or automatic scheduling of home appliances starting time. In this paper we present the results coming from social research conducted within project “e-balance – balancing energy production and consumption in energy efficient smart neighborhoods” realized within European 7FP. We outline four areas of potential social barriers for EMS adoption: engagement, unwillingness to leave appliances unattended, division of roles in the household and privacy concerns. Concluding, our studies indicate that the inclusion of the human perspective is necessary for the effective implementation of Energy Management Systems.

Surface Recalibration as a New Method Improving Gaze-Based Human-Computer Interaction

The main problem of a gaze-based interaction is the correct mapping from an output of eye tracker to a gaze point. In this paper we propose a new method of improvement of the gaze-based human computer interaction using: (a) a procedure to estimate the error introduced by screen tracking algorithms (surface recalibration) and (b) using the obtained error data to transform the eye-tracking data in real-time (data transformation). In order to test the developed method, we conducted initial pilot study using simple target pointing procedure. Initial data gathered during these tests shows that our method may increase the effectiveness (measured as target pointing speed) of the gaze-based interaction using mobile eye trackers. In future studies it is worth testing this method using stationary eye trackers as it can be an effective way of facilitating gaze-based interaction by counteracting calibration errors that would yield gaze-based system unusable.

Emotion dysregulation and impulsivity are important factors influencing the development and course of alcohol dependence. However, few empirical studies investigate the association between different aspects of impulsivity (cognitive, attentional, behavioral), emotion regulation, and alcohol use disorder symptoms in the same model. The goal of this study was to assess the association between emotion regulation and different facets of impulsivity among patients with an alcohol use disorder and healthy controls. The sample was comprised of 273 individuals: 180 participants with an alcohol use disorder undergoing inpatient alcohol treatment and 93 healthy controls. Emotion regulation was assessed using the Schutte Self-Report Emotional Intelligence Test subscale. Impulsivity was assessed with Barratt’s Impulsiveness Scale (BIS-11). Statistical models tested both the BIS-11 total score, as well as three secondary factors (non-planning, attentional, and motor impulsivity). Findings indicate that individuals with alcohol use disorder symptoms were characterized by poor emotion regulation and high levels of impulsivity in all analyzed domains. Moreover, path analytic models indicated that after accounting for demographic factors (i.e., biological sex, age, education) there was evidence for a significant indirect effect of alcohol use disorder symptomatology on non-planning and attentional impulsivity via emotion regulation. There was no association between emotion regulation and motor impulsivity. These findings indicate the importance of targeting emotion regulation skills as well as behavioral control when treating patients with alcohol use disorder.

A novel eye-tracked measure of the frequency of pupil diameteroscillation is proposed for capturing what is thought to bean indicator of cognitive load. The proposed metric, termedthe Index of Pupillary Activity, is shown to discriminate taskdifficulty vis-à-vis cognitive load (if the implied causality canbe assumed) in an experiment where participants performedeasy and difficult mental arithmetic tasks while fixating a centraltarget (a requirement for replication of prior work). Thepaper’s contribution is twofold: full documentaton is providedfor the calculation of the proposed measurement which can beconsidered as an alternative to the existing proprietary Index ofCognitive Activity (ICA). Thus, it is possible for researchersto replicate the experiment and build their own software whichimplements this measurement. Second, several aspects of theICA are approached in a more data-sensitive way with the goalof improving the measurement’s performance.

The Mann-Whitney test for the two-sample location problem is considered. We adopt this nonparametric test to interval-valued data perceived from the epistemic perspective, where the available observations are just interval-valued perceptions of the unknown true outcomes of the experiment. Unlike typical generalizations of statistical procedures into the interval-valued framework, the proposed test entails very low computational costs. However, the presence of interval-valued data results in set-valued p-value which leads no longer to a definite binary decision (reject or not reject the null hypothesis) but may indicate the abstention from making a final decision if the information is too vague.

Nowadays enterprises, including the smallest ones, are facing strong pressure of implementing innovative solutions, which are regarded as one of the key factors of the companies’ performance and de-velopment. Due to the immanent characteristics of hotel enterprises, knowledge derived from customers’ relations can play an important role in their innovation activities. The purpose of the article is to identify the importance of relations with customers in the innovative activities of hotel enterprises in Poland. The article presents the concept of User-Driven Innovation, as well as the current state of research on this issue in the tourism industry, particularly in hotel enterprises. The results of an empirical study conducted among 400 randomly selected hotels in Poland, are the key part of the article. According to the survey, customers’ relations play great role in the innovative activities of hotel enterprises. In addition, the main sources of inno-vations, as well as the scope of customer engagement in innovative activities are presented. Employees who directly contact the guests have a key role in acquiring and utilising knowledge coming from customers. The survey shows that Polish hotels are still at an early stage of adapting the concept of user-driven innovations. Moreover, the utilisation of knowledge from the clients for innovations requires intensification of the activi-ties in the field of knowledge, as well as human resources management.
