On Language Adequacy
2015
Abstract The paper concentrates on the problem of adequate reflection of fragments of reality via expressions of language and inter-subjective knowledge about these fragments, called here, in brief, language adequacy. This problem is formulated in several aspects, the most general one being: the compatibility of the language syntax with its bi-level semantics: intensional and extensional. In this paper, various aspects of language adequacy find their logical explication on the ground of the formal-logical theory of syntax T of any categorial language L generated by the so-called classical categorial grammar, and also on the ground of its extension to the bi-level, intensional and ex- tensio…
Students’ engagement in learning by indigenous knowledge-chemistry lesson
2022
This study was aimed at assessing students’ engagement in an integrated indigenous knowledge-chemistry lesson (IIK-CL) designed using the processes involved in cassava dough production. The paper focuses on the behavioural, emotional and cognitive engagement and their impact on students’ construction of knowledge of the factors affecting rate of chemical reactions. The study was conducted in Swedru senior high school in the Agona East municipality of the Central Region of Ghana. A purposively sampled intact class of 26 students aged between 14 and 18 years formed the study. The control group for this study encompassed also 26 students randomly sampled from the remaining chemistry classes in…
Food carotenoids and cancer prevention: an overview of current research
1997
Carotenoids are plant pigments that are present in the human diet as microcomponents of fruit and vegetables. Since 1980, a consistent bulk of the results from both epidemiologic and experimental studies has strongly suggested that β-carotene, a widespread food carotenoid with provitamin A activity, could prevent the onset of cancers, especially lung cancer. Unfortunately, subsequent large-scale intervention studies failed, with one exception, to demonstrate any chemopreventive potency for β-carotene supplementation in humans, revealing a lack of knowledge of the mechanisms involved. In addition to their antioxidant properties, which have long been thought to be the clue to their biological…
Emergence, evidence, and effect of junction clustering in supramolecular polymer materials
2021
A significant fraction of biomaterials consists of supramolecular polymers and networks formed by non-covalent interactions between associative motifs. They typically contain complex structures in which on top of binary associations, phase-separation and aggregation of associative junctions occur. Such hierarchical assemblies have significant influences on the dynamics as well as the physical and mechanical properties of the materials. Similar to supramolecular biomaterials, aggregation of associative junctions has also been frequently reported to occur in synthetic supramolecular polymers and networks. Engineering of such secondary structures in a sense to create and control the extent of …
Oxamato-based coordination polymers: recent advances in multifunctional magnetic materials
2014
The design and synthesis of novel examples of multifunctional magnetic materials based on the so-called coordination polymers (CPs) have become very attractive for chemists and physicists due to their potential applications in nanoscience and nanotechnology. However, their preparation is still an experimental challenge, which requires a deep knowledge of coordination chemistry and large skills in organic chemistry. The recent advances in this field using a molecular-programmed approach based on rational self-assembly methods which fully exploit the versatility of the coordination chemistry of the barely explored and evergreen family of N-substituted aromatic oligo(oxamato) ligands are prese…

Costruzione della Sicilian Experience. Il caso di Anna Tasca Lanza Cooking School
2020
La Sicilia è storicamente oggetto di narrative di stampo marcatamente edonistico, anche di recente casi rispecchiate e alimentate da casi editoriali di grande successo. Con l’imporsi di nuovi trend turistici improntati alla scoperta di specialità gastronomiche e vinicole locali, il settore turistico dell'isola gode di un ciclo particolarmente positivo. Le strutture di produzione e distribuzione agroalimentare e le realtà ricettive del territorio si stanno evolvendo per assecondare questo nuovo tipo di domanda, con effetti prevedibili di patrimonializzazione e ricostruzione semiotica della cultura alimentare tipica. Tra le realtà più in vista, nel settore, c’è la scuola di cucina Anna Tasca …
Impact of the knowledge society in the university and in scientific communication
2014
Over the last two decades, as a result of the introduction and intensive use of technologies for information and general knowledge, especially from the internet, the university is living in a process of complete transformation that affects it´s academic and organizational structures as well as the conception of educational methodology. The ICTs have demonstrated a need to establish coherent institutional strategies in their use and application, along with the possibility to expand the sphere of institutional action, in regards to general access to higher education. All of this shows an existing change from a model of education based on the transmission of knowledge, that was rather limited …
Alternatives to the present global development pattern : ecovillages – a model for sustainable living?
2016
Master thesis development management - University of Agder 2016 The current way of development is exhausting the planets limitations, the continues increase in consumption are degrading the nature that is relied on for human existence. Thus, it is necessary to define an alternative way of developing. The aim is to achieve happiness for all, sustaining the resources of the planet. Ecovillages are recognized as a sustainable alternative which encompasses a holistic approach to the term sustainability. Through qualitative research in the form of participatory observations, interviews and a survey performed in Gambhira, an ecovillage in rural Colombia, the sustainability, educational mission as…
