The Impact

The Function-based Behavioral Modeling (FBBM) design tool was introduced in prior work as a means of using formal functional modeling as the foundation for creating detailed mathematical models of system behavior. The overall objective of this work is to create a framework for partitioning modeling efforts into functional elements and promoting model storage and re-use through the use of functional models. In prior work, the FBBM method was introduced to model the complete vehicle dynamics of a Formula SAE racecar, highlighting the representation of functionality and the development of behavioral models. The objective of the work presented in the current paper is to demonstrate the ability to incorporate models of varying fidelity within a function-based behavioral model of a complex system. Additionally, the impact of model fidelity on the model’s predictions is addressed. A previously developed model is used as a foundation for developing the necessary new models and illustrating the impact of model fidelity on performance predictions when selecting a tire during early design. The results illustrate that the FBBM framework allows models of varying fidelity to be quickly made and their effect on predicted performance to be measured in order to assist critical early design choices.

The Impact

The paper focuses on the concept of cognitive-perceptual and behavioral model of communication. For semantic analysis, the news feeds of the online communication platform Reddit regarding the outcome of the pandemic – vaccination of the population – have been singled out as a linguistic material. Each post of news items has been previously thoroughly interpreted and analyzed. Such singling out of language material has been carried out with the help of linguistically obvious (explicit) and hidden (implicit) linguistic markers to denote certain semantic groups based on linguistic-semantic interpretation and analysis of the Reddit vaccination posts. As a result of the analysis, two communicative cognitive-perceptual and behavioral models of online communication within Reddit during the period of vaccination of the population have been studied. The first cognitive-perceptual and behavioral model – the general attitude towards vaccination, as well as the second one – the impact of vaccination on the population – have been considered. These models will further serve as a research basis of the pattern for social communicative approach concerning online Reddit discussions as both of them are based on the cognitive conceptualization notion referring to communication perception and behavior in certain communicative situations. To confirm the results of linguistic-semantic analysis, automatic software for counting words and providing concise linguistic information has been applied.

Introduction. The purpose of this study was to analyze L. S. Vygotsky’s cultural-historical psychology from the perspective of distinguishing the structure of the act of development within its framework and understanding its explanatory potential as a whole. This analysis enables to clarify and understand the essence of the digital and virtual shift. Moreover, it is required in order to overcome the limitations associated with the currently dominant behavioral models, which are used by researchers in their attempts to explain and describe the phenomenon of the influence of digital technologies on people, in particular, on schoolchildren and students. Materials and Methods. The paper considers the concept derived from L. S. Vygotsky’s cultural-historical psychology, which is proposed to be adopted as a basic one in order to build an explanatory model used by the author to describe and comprehend the phenomenon of transformation of the human development process in the new reality of the digital environment. Results. The article introduces the basic principles and provisions, the explanatory model is built on, concerning the role of symbolic-instrumental mediation in human development, the role of an adult as a mediator, the structure of the act of thinking and the act of development, the basic mechanism of mastering a person's behavior, which permeates the formation of higher mental functions. The author compares this explanatory model and the behavioral model used in most modern research investigations that examine the impact of digital technologies on schoolchildren and students. Conclusions. The findings show that the student is presented in the behavioral model as a passive reactive being that reacts to external stimuli. In this sense, a human being is not treated as a personality with highest abilities, but is considered as a function. The proposed model cannot be used to explain and comprehend modern development processes.

The Impact

Previous studies have identified that a behavior can occur through the strongest predictor intention, but there is a gap between intention and behavior. Dopamine receptor D2 (DRD2) is known to account for a variance in sporting behaviors in human and animal subjects. However, the relationship between DRD2 and sport participation has been poorly studied, and the limited available reports are inconsistent. The present study was performed to examine the impact of DRD2 on sport participation among Korean university students based on the integrated behavioral model (IBM). Data were collected from enrolled university students in Seoul (N = 45). Participants answered survey questions first, and then they gave investigators their hair to provide DNA information (i.e., the A1 allele of DRD2). DRD2 had a significant effect on sport participation, but only in male students. Male students who carried the A1 allele of DRD2 significantly participated in 105.10 min more sporting activities than male students who did not. Moreover, the effect of intention on sport participation was significantly decreased when considering DRD2. Despite the small sample size, the results of this study could be a preliminary case for a larger study and indicate the direction of future research. Our results suggest that DRD2 may have played an important role as the “actual skill” shown in the IBM.

Abstract Behavior change is an inherent aspect of routine geriatric care. However, most research and clinical programs emphasis how to initiate behavior change with less emphasis placed on skills and strategies to maintain behaviors over time, including after an intervention has concluded. This presentation will provide an introduction to the symposium, including a review of prior work and our rationale for studying the critical yet overlooked construct of maintenance in older adults. Several key considerations in our work include the impact of multiple chronic conditions, declines in cognitive and functional capacity over time, changes in environmental context and/or social support, and sustainability of community and population-level programs and services.

Failure Identification

In this paper, a design-stage failure identification framework is proposed using a modeling and simulation approach based on Dimensional Analysis and qualitative physics. The proposed framework is intended to provide a new approach to model the behavior in the Functional-Failure Identification and Propagation (FFIP) framework, which estimates potential faults and their propagation paths under critical event scenarios. The initial FFIP framework is based on combining hierarchical system models of functionality and configuration, with behavioral simulation and qualitative reasoning. This paper proposes to develop a behavioral model derived from information available at the configuration level. Specifically, the new behavioral model uses design variables, which are associated with units and quantities (i.e., Mass, Length, Time, etc…). The proposed framework continues the work to allow the analysis of functional failures and fault propagation at a highly abstract system concept level before any potentially high-cost design commitments are made. The main contribution in this paper consists of developing component behavioral models based on the combination of fundamental design variables used to describe components and their units or quantities, more precisely describing components’ behavior.

Abstract While electronic word-of-mouth (eWOM) variables, such as volume and valence have been posited in previous studies to consistently affect product sales, there is a lack of studies on the different contexts and outcomes that affect the importance of eWOM variables. In order to fill this gap, this study attempts to use the helpfulness of reviews and reviewers as moderators to predict box office revenue, comparing the prediction performances of business intelligence (BI) methods (random forest, decision trees using boosting, the k-nearest neighbor method, discriminant analysis) using eWOM between high and low review or reviewer helpfulness subsample in the Korean movie market scrawled from the Naver Movies website. The results of applying machine learning methods show that movies with more helpful reviews or those that are reviewed by more helpful reviewers show greater prediction performance, and review and reviewer helpfulness improve the prediction power of eWOM for box office revenue. The prediction performance will improve if the characteristics of eWOM are likely to be combined to contribute to box office revenue to a greater extent.
