Chapter 1 Amalgams, Colimits, and Conceptual Blending
2018
This chapter is a theoretical exploration of Joseph Goguen’s category-theoretic model of conceptual blending and presents an alternative proposal to model blending as amalgams, which were originally proposed as a method for knowledge transfer in case-based reasoning. The chapter concludes with a generalisation of the amalgam-based model by relating it to the notion of colimit, thus providing a category-theoretic characterisation of amalgams that is ultimately computationally realisable.
How Body and Soul Interact with the Spiritual Mind: Multimodal Cognitive Semiotics of Religious Discourse
2008
Cognitive Linguistics as an enterprise provides new theoretical and methodological instruments in understanding the relationship between people's thoughts and the language they use. Spiritual and religious experiences (particularly the ones involving some type of revelation from or communication with a transcendent being) are especially interesting since they involve some type of external, physically invisible force or agent, contributing an "ineffable" quality to the phenomenon. However, people can and do describe such events, and metaphors and blends pervade the representations of certain concepts of the transcendental when attempting to talk about such abstract ideas. One of the main ten…
Relation of Interdiffusion and Self-Diffusion in Polymer Mixtures
1986
From different assumptions one obtains linear relationships either between the interdiffusion coefficient and the self-diffusion coefficients or between the inverse interdiffusion coefficient and the inverse self-diffusion coefficients. The nature of these assumptions and possible experiments for discriminating between them are discussed.
Making Floryr–Huggins Practical: Thermodynamics of Polymer-Containing Mixtures
2010
The theoretical part of this article demonstrates how the original Flory–Huggins theory can be extended to describe the thermodynamic behavior of polymer-containing mixtures quantitatively. This progress is achieved by accounting for two features of macromolecules that the original approach ignores: the effects of chain connectivity in the case of dilute solutions, and the ability of polymer coils to change their spatial extension in response to alterations in their molecular environment. In the general case, this approach leads to composition-dependent interaction parameters, which can for most binary systems be described by means of two physically meaningful parameters; systems involving …
Solubility of Polymers
2011
Detailed knowledge concerning the phase state (homogeneous or coexistence of two or more condensed phases) of polymer containing mixtures is indispensible in virtually any area related to the production or application of macromolecules. In addition to this qualitative information it is for many purposes highly desirable to dispose of quantitative data regarding solvent quality or, more generally, with respect to the thermodynamic interaction between the components of the mixtures. This contribution starts with a brief presentation of the thermodynamic criteria deciding on the phase state and presents the experimental methods used in this area. The next section gives an overview on typical b…
Conceptualising Design of Learning Management Systems to Address Institutional Realities
2018
There is growing interest in the use of E-Learning in higher educational institutions. However, studies have shown mismatches between Learning Management System (LMS) design and the general institutional context in developing countries. In this paper, we assess the design and implementation requirements for Makerere University LMS against the overall institution context. This research follows a qualitative method (interviews) and uses case study. We employ the design reality gap model to investigate the design requirements of the LMS against current institutional realities. A design reality gap of 46 was obtained implying ad-hoc measures need to be put in place otherwise the failure/stagnat…
Post-collisional adakite-like magmatism in the Ağvanis Massif and implications for the evolution of the Eocene magmatism in the Eastern Pontides (NE …
2011
In the Anatolia, the Caucasus and northwest Iran, the Eocene epoch is characterized by widespread basic to acidic magmatism, whose temporal and spatial evolutions and origin are poorly understood. In this paper, we provide geochronological and geochemical data on a suite of Early Eocene intrusions from northeast Turkey and discuss their origin within a regional tectonic framework. Post to late-collisional, moderate to small bodies of quartz diorite and leucogranodiorite as well as later dacite porphyries intrude Permo-Triassic low-grade metamorphic rocks in the southern part of the Eastern Pontides very close to the Neo-Tethyan Izmir-Ankara-Erzincan suture. In places, the intrusives display…
The Patras blended strategy model for deep and meaningful learning in quality life-long distance education
2019
Life‑long learning is currently being embraced as a central process that could disrupt traditional educational paths. Apparently, the (ideal) type of learning often promoted is deep and meaningful learning, though it is not always required to be so. Deep learning goes beyond superficial knowledge assimilation of unlinked facts; it aims at developing deep disciplinary understanding, transformative knowledge, personal meaning, emotional intelligence, critical thinking, creativity and metacognitive skills. Meaningful learning occurs when learning is active, constructive, intentional, authentic, and cooperative. Technology enhanced teaching and learning methods should prove their potential to t…
Encouraging blended learning and ICT use at Universitat de València to improve the learning process with the .LRN platform
2007
The Universitat de Valencia, one of the largest, oldest and most varied in Spain, concerned about the efficiency of the learning processes in the context of the convergence process towards the Higher Education European Space, has conducted educative innovation experiences in several degrees, diversifying learning activities.Interested in enhancing traditional classroom learning by use of ICT (with progressive blended learning introduction) has established a learning management system to enhance the learning and communication processes for the whole university. The overall goal was to build skills in ICT use in order to improve learning process quality and student participation.This paper de…
Supporting Learning Groups in Online Learning Environment
2015
In this paper, we report on the initial findings on how to effectively support learning groups in online learning environments. Based on the idea that learning groups can enhance effective learning in online learning environments, we used qualitative research methods to study learning groups (interviews and observation of learning group interactions in online learning environments) and their facilitators. Preliminary results reveal that in order to have effective learning groups you need to take care of the following online design issues: develop comprehensive study guides, train online tutors, motivate learners through feedback, and foster high cognitive levels of interaction through quest…
