Basic Concepts

Educational content of many kinds and from many disciplines are increasingly presented in the form of short videos made broadly accessible via platforms such as YouTube. We argue that understanding how such communicative forms function effectively (or not) demands a more thorough theoretical foundation in the principles of multimodal communication that is also capable of engaging with, and driving, empirical studies. We introduce the basic concepts adopted and discuss an empirical study showing how functional measures derived from the theory of multimodality we employ and results from a recipient-based study that we conducted align. We situate these results with respect to the state of the art in cognitive research in multimodal learning and argue that the more complex multimodal interactions and artifacts become, the more a fine-grained view of multimodal communication of the kind we propose will be essential for engaging with such media, both theoretically and empirically.

This paper examines the interface between fine-grained and coarse-grained programmable logic in FPGAs. Specifically, it presents an empirical study that covers the location, pin arrangement, and interconnect between embedded floating point units (FPUs) and the fine-grained logic fabric in FPGAs. It also studies this interface in FPGAs which contain both FPUs and embedded memories. The results show that (1) FPUs should have a square aspect ratio; (2) they should be positioned near the center of the FPGA; (3) their I/O pins should be arranged around all four sides of the FPU; (4) embedded memory should be located between the FPUs; and (5) connecting higher I/O density coarse-grained blocks increases the demand for routing resources. The hybrid FPGAs with embedded memory required 12% wider channels than the case where embedded memory is not used.

The article presents the results of an empirical study related to the problem of the risks of digitalization of social contacts when searching for marriage partners through dating sites. The research hypothesis suggests that these risks are fraud; sexual harassment; stalking; abuse of received information of an intimate nature; distortion of perception of the communicative situation, reality, communication partner; the occurrence of negative psychological consequences. It is assumed that the risks will increase due to the characteristics of the personality of women. The respondents were 197 women who used dating sites to find a marriage partner. A specially developed author's questionnaire was used, as well as standardized methods. It was revealed that such types of risks as fraud, sexual harassment occur regardless of the personal characteristics of the respondents. Risk of facing fraud increases among successful women. Risk of the distortion of the perception of the communicative situation, reality, communication partner and risk of the occurrence of negative psychological consequences directly depend on the personal characteristics of women.

Inference Algorithms

This chapter presents a sleep monitoring system based on WISP tags. The authors show that their system accurately infers fine-grained body positions from accelerometer data collected from the WISP tags attached to the sides of a bed. Movements, duration, and bed entrances and exits are also detected by the system. The chapter presents the results of an empirical study from 10 subjects on three different mattresses in controlled experiments to show the accuracy of the inference algorithms. The authors also evaluate the accuracy of the movement detection and body position inference for six nights on one subject, and compare these results with two baseline systems. Preliminary data investigating the correlation between sleep stages from the Zeo and movement is also presented.

Emotional Burnout

The purpose of the article is to describe the results of an empirical study of resilience as a factor of resistance to burnout syndrome. The leading methods in this study are the questionnaire "Adults' resilience", "Diagnostics of emotional burnout of an individual", "Strategies for overcoming stressful situations". As a result of the study, it was found that resilience is a factor of resistance to burnout syndrome. In most participants, the indicators of resilience increase with age, which reflects the development of self-efficacy, perseverance, awareness of the importance of family and social contacts, preference for assertiveness, and prosocial coping. The materials of the article can be helpful in psychological support of individual groups, the development of resilience in various groups, in the professional activities of teachers and psychologists. In addition, the results can be used in the educational process of future psychologists and programs of other academic disciplines.

Group Trust

This paper refers to the widespread notion that voluntary (sport) organizations produce social capital, popularized through the works of Robert D. Putnam, and compares social trust levels of sport club members with members in other voluntary associations and non-members. We differentiate between in-group trust and out-group trust, highlighting that not only the level of trust but also the “trust radius” counts for social cohesion in modern societies. Refining Putnam’s claims, we argue that social trust among members varies with the quality and intensity of participation captured (for instance, through volunteering), diverse social contacts and the level of membership trust experienced in an association. Based on a nation-wide survey, carried out in Germany during 2017/2018, it is demonstrated that members of civic associations indicate higher levels of trust towards in-groups and out-groups compared to non-members and they regard present society as more solidary and trusting. A fine-grained analysis among members of associations further shows that increased trust is typical for volunteers and individuals in socially diverse associations which, at the same time, are characterized by high levels of membership trust. We conclude that sports clubs need to provide beneficial context conditions for producing high levels and a wider radius of trust.

The Relationship

In this article, we introduce a framework that can be used by organizations as a positioning instrument to think of business-ICT alignment decisions in light of the strategic importance of ICT (Information and Communication Technology) in their organization. We make a distinction between organizations where ICT is of high strategic importance and those where ICT is of low strategic importance. Based on this difference we argue that heavily investing in business-ICT alignment processes, structures and roles (PSRs) will not necessarily always be beneficial when ICT is of low strategic importance to the business. Furthermore, organizations that have a minimalist approach to the use of ICT do not necessarily need to invest in business-ICT alignment PSRs. We explain the dynamics and possible migration scenarios of our proposed framework after testing the statistical significance of the relationship between the strategic importance of ICT and the investment in business-ICT alignment. We end this article with a short empirical study which combines survey and case study results. Both the framework and framework dynamics still need further empirical validation, preferably with longitudinal data. Therefore, we stress and acknowledge that many of the discussions in this article are still explorative in nature. However, this article illustrates the possibilities and the need for a more fine-grained approach to business-ICT alignment.

Discourse Connectives

Abstract While the role of discourse connectives has long been acknowledged in argumentative frameworks, these approaches often take a coarse-grained approach to connectives, treating them as a unified group having similar effects on argumentation. Based on an empirical study of the straw man fallacy, we argue that a more fine-grained approach is needed to explain the role of each connective and illustrate their specificities. We first present an original corpus study detailing the main features of four causal connectives in French that speakers routinely use to attribute meaning to another speaker (puisque, étant donné que, vu que and comme), which is a key element of straw man fallacies. We then assess the influence of each of these connectives in a series of controlled experiments. Our results indicate each connective has different effects for the persuasiveness of straw man fallacies, and that these effects can be explained by differences in their semantic profile, as evidenced in our corpus study. Taken together, our results demonstrate that connectives are important for argumentation but should be analyzed individually, and that the study of fallacies should include a fine-grained analysis of the linguistic elements typically used in their formulation.
