Universal Reasons for Low Participation in Chinese and Western Undergraduate Classrooms

This study regards low classroom participation as a global issue and investigates the universal reasons for this problem shared by the undergraduate students in China and in the west. Participating in class discussions and asking questions are instrumental for effective learning. This study regards low classroom participation as the phenomenal where students do not ask or answer questions during a lesson. The research was conducted by combining profound experiences and insights developed as an undergraduate student in the University of Waterloo and a teaching assistant in Soochow University with the understanding of both Chinese academic articles and western academic articles about this topic. This study reveals the reason why Chinese and western undergraduate classrooms experience low classroom participation is that their stakeholders focus on the competing goals. This study defines the stakeholders as the instructors, students and the post-secondary institutions

Solar Air Heating Collectors in two Modular Solar Panels built into a "Do-It-Yourself" type project

These days, people have been talking a lot about renewable energy. The world is growing too dependent on non-renewable energy, such as fossil fuel, natural gas, oil and coal. There needs to be another idea to be green and environmentally friendly. And with the use of renewable energy source, the world can be a better place. These renewable energy sources can be used for hundreds of years without hurting the environment. There has been much research going on in science labs and farms across the country, so these sources are always evolving into better and better things. The sources are almost limitless, but there are some common ones. The most widely used heating installations in current technologies are based on burning fossil fuel but we should take in consideration that health policies nowadays are directed towards lowering the use of this kind of fuel. This paper presents the processes of designing and development of a heating system that uses entirely solar energy. The heating system consists of two parts. The first part consists of a photovoltaic solar panel made from 36 photovoltaic cells capable of developing 65 W and 3.6 A. The second part is made of recycled materials (aluminum cans), forming radiant tubes

The purpose of the research is to obtain composite materials with high structural, thermo-mechanical and / or tribological performances, according to ecological norms and international requirements in order to replace the existing classical materials, setting up current, innovative and high performance solutions, for applications in top areas such as automotive industry and not only. The objective of the research is to develop new fully / partially biodegradable composite materials by using new natural fibers and those recovered from various wastes. The research aims to obtain some composites with matrix of various types of polymeric materials and the reinforcement phase of textile materials (of different natures) so that the resulting products to be biodegradable. The textile inserts used as raffle are ecological, non-toxic and biodegradable and they contain (divided or in combination) bast fibers (flax, hemp, jute) and other vegetable fibers (cotton, wool) as plain yarn or fabric, which can replace the glass fibers, commonly used in polymeric composites

Influence of gastrointestinal digests of glycated whey protein on the hormone secretion of enteroendocrine cells

The present research used two α-dicarbonyl compounds, glyoxal and methylglyoxal and whey protein as subjects, and evaluated the alterations of physicochemical properties, structure, and digestibility of whey protein throughout the glycation process. The STC-1 cells were used as a model to investigate the implications of glycation on the protein nutrition sensing of enteroendocrine cells. Results showed that glycation substantially enhanced the surface hydrophilicity and solubility of whey protein. Additionally, the incorporation of sugar chain structure introduced steric hindrance, facilitating the binding of the free amino group of lysine and resulting in the formation of macromolecular crosslinking glycation structures. These structures potentially hindered the function of gastrointestinal digestive enzymes, thus reducing the degree of digestion. Furthermore, the gastric and intestinal digests of glycated whey protein variably modulated the intestinal hormone secretion of STC-1 cells and elevated the mRNA levels of pertinent hormones. Derived patterns of the effect of the gastrointestinal digestion products of glycated proteins on the level of hormone secretion in enteroendocrine cells

notizie sull insegnamento di lingua letteratura e cultura romena presso la regia scuola superiore di commercio la facolta di economia e commercio e l universita ca foscari venezia

The aim of this research is to retrace the evolution of the academic study of Romanian at Ca' Foscari University, from its introduction in the second half of the 19th century to the present day, introducing a series of unpublished documents. The study highlights the most important periods for the above-mentioned course: 1883/84 – 1891 when Professor Marco Antonio Canini founded the Romanian language and culture course at Regia Scuola Superiore di Commercio di Venezia, the 1940s when Anna Potop was appointed Professor of Romanian at the Istituto Universitario di Economia e di Commercio, the 1970s when Sorin Stati coordinated courses of Romanian language and culture and ending with the late 1990s and 2000s when the courses were reinstated due to the collaboration between the Istituto Romeno di Cultura e Ricerca Umanistica di Venezia and Ca' Foscari University

Appartenere ad altri luoghi fra letteratura e realt\ue0. Nuove relazioni tra spazio e identit\ue0 nella prosa italiana e romena degli ultimi decenni

Vivere la tarda modernit\ue0 sta diventando pi\uf9 che mai sinonimo di abitare la metropoli della mente dove i sensi dello spazio, dell\u2019identit\ue0 e dell\u2019appartenenza vengono di continuo rimessi in discussione, inventati, immaginati. Una nuova identit\ue0, molteplice e dinamica, protesa a trasgredire e ad esplorare nuovi percorsi di manifestazione sta aspettando la sua riscrittura che non tarda ad arrivare. E i luoghi acquistano significato in quanto si fanno dimora di questa molteplicit\ue0 rimodellandosi come spazi pronti a essere attraversati, trasgrediti, evasi. \uc8 evidente che la letteratura recente non vive pi\uf9 dell\u2019euforia della permanenza in un solo luogo ma dell\u2019avventura della dislocazione, della continua erranza che per Walter Benjamin si prefigurava come \uab metafora provvisoria dell\u2019essere e del dover essere della soggettivit\ue0 postmoderna \ubb, della convinzione che \uab siamo fatti della stessa carne di cui sono fatti i luoghi e che per questo tra noi e loro c\u2019\ue8 una strana corrispondenza e somiglianza. Siamo le mappe di noi stessi e dei luoghi che ci circondano, cos\uec come questi diventano mappe del nostro corpo e dei nostri sensi \ubb, come affermava Franco La Cecla. Percorrendo altri luoghi, diversi da quelli di origine, ci si pu\uf2 imbattere in quel centro del mondo rappresentato originariamente ed in senso ontologico dalla casa \u2013 come ci ricorda Mircea Eliade \u2013 laddove tutto ricomincia e si pu\uf2 ripetere all\u2019infinito il gesto demiurgico. La scrittura contemporanea dell\u2019identit\ue0 che si delinea attraverso le opere romene e italiane prese in esame implica una complessa relazione con l\u2019Altro e l\u2019Altrove. L\u2019identit\ue0 si rivela non tanto un attributo o una qualit\ue0 di un soggetto quanto una relazione tra il soggetto e gli altri, tra il soggetto e lo spazio. Dato che si tratta di un concetto che scorre attraverso pi\uf9 livelli di realt\ue0, tale relazione diventa un punto di naturale incrocio dei saperi, di discipline diverse. Abbiamo affidato l\u2019analisi e la lettura dei tratti mobili e molteplici che l\u2019identit\ue0 contemporanea acquisisce ad un approccio critico in cui gli strumenti tematologici si intrecciano con quelli imagologici, dei Cultural studies, sociologici, psicologici e della storia delle mentalit\ue0. Alla prosa romena degli ultimi decenni \ue8 dedicata la prima parte della mia tesi e sono stati oggetto di analisi romanzi e racconti ma anche diari e carteggi scritti sia in Romania che all\u2019estero. Apprendiamo che l\u2019identit\ue0 nazionale romena cos\uec come molteplici identit\ue0 individuali romene si sono costruite nel corso del tempo in funzione sia di un altrove reale e raggiungibile che di uno spazio immaginario, sognato e ricreato nella terra d\u2019origine...Living the late modern times means more than ever inhabiting the city of mind where senses of space, of identity and of belonging are continually talked of, invented, imagined. A new, multiple and dynamic identity, aspiring to cross over and to explore new ways of manifestation is expecting to be rewritten and it seems that time has already come. Places acquire meaning as they house this multiplicity modeling themselves as spaces ready to be crossed, escaped from. It\u2019s obvious that the recent literature delights no more in the euphoria of permanence in one place but in the adventure of dislocation, of the unceasing wandering which Walter Benjamin conceived as \uab temporary metaphor of being and of having to be of postmodern subjectivity \ubb, of the conviction that \uab we are made from the same stuff that places are made from, that\u2019s why there is a strange correspondence and likeness between us and them. As we are the maps of ourselves and of the places around us so the places become maps of our bodies and of our senses \ubb (Franco La Cecla). Traveling across other places, different from the birthplaces, it\u2019s possible to reach that center of the world represented ontologically by home \u2013 as Mircea Eliade reminds us \u2013 where everything starts from the beginning and the divine gesture can be repeated without end. Contemporary writing about identity as traced by the Romanian and Italian works we analyzed implies a complex relationship with the Other an the Elsewhere. Identity is revealed to be not much an attribute or a quality of a subject as a relation between subject and the others, between subject and space. As we talk about a concept that looms in different aspects of reality, these relations become natural crossroads of fields, of different disciplines. So we based our analyze and reading of the mobile and multiple features that contemporary identity acquires on a critical approach which combines instruments belonging to thematology, imagology, Cultural Studies, sociology, psychology, and history of mentality. I dedicated the first two chapters of my work to Romanian prose written in the last decades and I took into consideration novels and short stories but also journals and correspondences written in Romania and abroad. All these works outline how Romanian national identity but also many Romanian individual identities have been creating themselves in dependence on a real and reachable space as on an imaginary space, longed for and rebuild in the native country..
