Systemic technology innovation management and analysis of other forms of IP protection

Industry 4.0 and the pandemic have caused recent changes in innovative development, economic situations, and restrictions in various companies and regions of the world, with new stricter legislation related to working conditions, hygiene standards, and health requirements. New technologies are a challenge to the transformation of problem companies and regions, as they often significantly impact economic development. Technological emissions, growing information on dementia among young people, cyber risks, and the risks of so-called advanced technologies (e.g., bio- and nanotechnologies, Industry 4.0 tech) may raise societal concerns about technological progress. This study is part of our long-term research into technological innovation in different companies and regions. Its primary goal is to methodically emphasize the importance and role of the systemic management of technological innovation in companies and regions and analytically compare the innovation success of differently developed regions from a global perspective¹. This research deals with an important aspect of technology management, namely, the processes of technological identification and the protection of related intellectual property (IP). The primary research question is: How has technological development been distributed across different regions over the last two decades? We hypothesize that Asian countries are increasingly moving away from Europe and North America in terms of technological innovation, other forms of technological IP protection, and overall access to innovation, while the focus is on the development of three non-patent forms of technological innovation protection: industrial designs, trademarks, and utility models. The results of our study reveal a significant difference in the approach to technological innovation management and the form of IP protection between so-called advanced and problem companies and regions. This study was conducted between 2018 and 2022.     

Semiotics and the “Connections” Standard: Significance of Semiotics for Teachers of Mathematics

For more than 14 years, the National Council of Teachers of Mathematics (1989, 2000) has advocated that teachers of mathematics facilitate that students make connections of various kinds, in their learning of mathematics. Semiotic theories, including those of Peirce and those of Saussure and Lacan (each for different purposes), provide useful lenses for examining ways that teachers may facilitate the making of connections, for instance between home and school mathematics, or between mathematics and other school subjects, or between different branches of mathematics. This paper describes a nested chaining model that takes into account the need for interpretation and meaning making at each step in the sequences involved in connections. A nested model has the capacity to allow for webs of signification and meaning that take into account the complexity of the processes in ways that linear semiotic chains cannot. Examples are taken from research projects with graduate students, with pre-service teachers, and with practicing teachers.

Specifying and Interpreting Latent State–Trait Models With Autoregression: An Illustration

Latent state–trait models are valuable tools for representing the longitudinal stability and variability of individuals’ relative standing on a construct (e.g., a behavior or psychological process). Specifically, state–trait models partition construct variance into time-varying and time-invariant components, enabling one to examine the relations between these components and other variables. Such partitioning of construct variance has a number of valuable applications including the improvement of risk-outcome research. The trait–state–occasion (TSO) model and latent state–trait model with autoregression (LST–AR) are ideal for use with constructs with relative stability that decreases with increasing durations, but relative stability that does not decrease to 0 even over long durations. Despite the fact that this pattern of relative stability expression is observed for a wide variety of constructs, there are relatively few applications of the TSO and LST–AR models. Thus, this article describes the TSO and LST–AR models and illustrates application of these models.

“Double-Dose” Algebra as an Alternative Strategy to Remediation: Effects on Students' Academic Outcomes

Abstract

Expanded instructional time has become increasingly popular as a strategy to improve the academic outcomes of low-skilled students, particularly in the 9th grade. We evaluate the efficacy of a double-period algebra policy initiated in the Chicago Public Schools in 2003. This policy required all students with 8th-grade test scores below the national median to enroll in a support algebra course in addition to regular algebra in the 9th grade. Using regression discontinuity combined with interrupted time series designs, and instrumental variable models, we show the effects of the policy on students' grades, failure rates and test scores in 9th-grade algebra and 10th-grade geometry. Providing support courses improved algebra test scores for the target population but only modestly affected grades and failure rates. Students with very low initial abilities benefited less than students close to the national median. The policy also led schools to track algebra classes by students' entering math skills. As a result, it affected academic outcomes among students not targeted by the policy; test scores among high-ability students improved whereas their grades declined.     

Visualising learning design to foster and support good practice and creativity

Applying Bandura's social learning theory, this paper proposes a theoretical framework for analysing the effect of MUD playing on users' self efficacy. Three types of self efficacy – computer self efficacy (CSE), social self efficacy (SSE) and generalized self efficacy (GSE) – are introduced. A possible hypothesis – successful performance, vicarious experience, hearing positive verbal persuasion and massive exposure during MUD playing will raise the CSE, SSE, and GSE of users – is suggested. Finally, a theoretical model explaining the relationship between self efficacy and MUD activities is proposed.

Applicant la théorie de l'apprentissage de Bandura cet article propose un cadre théorique pour analyser les effets de MUD jouant sur l'efficacité personnelle de l'utilisateur. 3 types de celles-ci - computer self-efficiency (CSE) social self efficacy (SSE) et generalisé self-efficiency (GSE) - sont introduits et une hypothèse possible. Les résultats réussis, expérience substituée, écoute de la persuasion verbalement et l'exposition massive au jeu de MUD augmentera le CSE, SSE et GSE des utilisateurs est suggéreé. Finalement un modèle théoritique expliquant le rapport entre l'efficacité personnelle et les activités de MUD est proposé. NDLR. Beaucoup de termes sont introduisable en francais et ont dû être maintenus en anglais.

(MUD: multi-user domain, multi-user dungeon, oder multi-user dimension; eine (virtuelle) Umgebung, in der mehrere Menschen (Spieler) gleichzeitig eingeloggt sein können, um miteinander zu agieren (Rollenspiele).?/?Efficacy: wörtl.: Wirksamkeit - Der Übersetzer). Unter Anwendung von Banduras Sozialer Lerntheorie wird in diesem Beitrag ein theoretischer Rahmen vorgestellt, mit dessen Hilfe man die Wirkung des MUD-Spielens auf das Selbstvertrauen der Teilnehmer analysieren kann. Es werden drei Arten dieses Selbstvertrauens eingeführt - Computer self efficacy (CSE), Social self efficacy (SSE) und Generalized self Efficacy (GSE). Die Hypothese ist, dass durch die erfolgreiche Durchführung Ersatzerfahrungen, das Hören positiver verbaler Bestätigung und das massives Ausgeliefertsein während des MUD-Spielens das Selbstbewußtsein (CSE, SSE und GSE) des Spielers erhöht wird. Zum Schluss wird ein theoretisches Modell zur Beziehung zwischen Selbstvertrauen und MUD-Aktivitäten vorgestellt.
