Chemical communication in the Mozambique tilapia: a role for amino acids

The Mozambique tilapia (Oreochromis mossambicus) is a maternal mouthbrooding cichlid from the southern Africa. The olfactory sensitivity of the species to 20 amino acids was assessed using the electro-olfactogram (EOG). We estimated whether the olfactory potency of the polar fraction of male urine can be explained by the presence of identified amino acids. In addition, filtrate and amino acid mixture of the urine of Nile tilapia were used to estimate their olfactory potency for O.mossambicus. Finally, concentrations of the main amino acids were measured in the urine of males of different social status and the correlations between amino acid concentration and hierarchical status were explored. L-cysteine, L-glutamine and L-threonine were the most potent stimuli at M while L-proline and L-aspartate were the least potent. Four groups of amino acids were identified according to their thresholds of detection and three groups – according to the similarity of their ɣ-factors. The estimated threshold of detection for O.mossambicus mixture was higher than that for the filtrate. On the contrary, the threshold of detection for the mixture of Nile tilapia was lower than that for the filtrate The concentration of L-arginine in the urine was positively correlated with fish dominance index. Both L-arginine and L-glutamic acid concentrations had much greater variability in dominant males (DI˃0.5) than in subordinate males (DI˂0.5). The urinary concentrations of L-phenylalanine had similar variability in dominant and subordinate groups. The Mozambique tilapia has olfactory sensitivity to all twenty amino acids tested. The fish showed more acute sensitivity to conspecific urine filtrate than to the heterospecific. Olfactory potency of O.mossambicus filtrate can be largely but not fully explained by the presence of L-arginine, L-glutamic acid and L-phenylalanine. Larginine and L-glutamic acid may indicate the dominance status of the fish and, possibly, individual identity.

Cultural organizations and communication in portuguese decentralization policy

This presentation intends to show to what extent the Portuguese municipalities’ commitment, from the first decade of this century, in cultural facilities of municipal management and which has provided 12 of the 18 district capitals of mainland Portugal with equipment, resulted in a regular, diverse and innovative schedule. Investing in urban regeneration, local government has tried to convert cities’ demographic changes (strengthening of the most educated and professionally qualified groups) in effective cultural demands that consolidate the three axes of development competitiveness-innovation-creativity. What the empirical study to the programming and communication proposals of those equipment shows is that it is not enough to provide cities with facilities; to escape to a utilitarian conception of culture, there is a whole work to be done so that such equipment be experienced and felt as new public sphere. Equipment in which proposals go through a fluid bind, constructed through space and discourse with local community, devotes a diversified and innovative bet full filling development axis. This paper presents in a systematic way what contributes to this binding on the analyzed equipment.

LSP communication in a digital age: the outcomes of teaching and learning in tertiary education

This paper discusses the changes brought by the communication revolution in teaching and learning in the scope of LSP. Its aim is to provide an insight on how teaching which was bi-dimensional, turned into a multidimensional system, gathering other complementary resources that have transformed, in a incredibly short time, the ways we receive share and store information, for instance as professionals, and keep in touch with our peers. The increasing rise of electronic publications, the incredible boom of social and professional networks, search engines, blogs, list servs, forums, e-mail blasts, Facebook pages, YouTube contents, Tweets and Apps, have twisted the way information is conveyed. Classes ceased to be predictable and have been empowered by digital platforms, innumerous and different data repositories (TILDE, IATE, LINGUEE, and so many other terminological data banks) that have definitely transformed the academic world in general and tertiary education in particular. There is a bulk of information to be digested by students, who are no longer passive but instead responsible and active for their academic outcomes. The question is whether they possess the tools to select only what is accurate and important for a certain subject or assignment, due to that overflow? Due to the reduction of the number of course years in most degrees, after the implementation of Bologna and the shrinking of the curricula contents, have students the possibility of developing critical thinking? Both teaching and learning rely on digital resources to improve the speed of the spreading of knowledge. But have those changes been effective to promote really communication? Furthermore, with the increasing Apps that have already been developed and will continue to appear for learning foreign languages, for translation among others, will the students feel the need of learning them once they have those Apps. These are some the questions we would like to discuss in our paper.

The impact of in-store activations (communication) in the consumer's emotions

Consumer behavior: Sport Zone. The analysis of "The impact of in-store activations (communication) in the consumer's emotions" Several studies have been conducted on the consumer behavior. This study aims to analyze and understand which factors are important to consumers’ emotions when the purchase decision occurs, the brand awareness, brand loyalty and the campaigns/activations’ impact in the above factors. Two research surveys were conducted to realize this study, the first online and the other was an interview to the Agency Up Partner who conceived and put into practice this Fitness campaign. First of all, was the consumer’s survey, a survey with 100 answers, to understand which factors are taken into account when a campaign in-store is held, in which the atmosphere is mainly used to arouse consumer’s desire to purchase, and also emotions. Second, the interview with the agency was realized to find out on what they were based on when they delineate it, and if the raise of emotions was taken into account in the origin of it. Concluding, emotions have a significant impact on formation of consumer in-store behavior, satisfaction and loyalty. As we could assay through of how this Fitness campaign was carried out as well as the optimal feedback received by consumers, improved attention over in-store marketing activity strongly influences consumer behavior at the point of purchase. “Sport Zone: A new store concept where the love for sports is combined with functionality”

Developmental patterns of individiuals within a sensory-based learning environment in art education : insights emerging from a case study /

My research permitted me to reexamine my recent evaluations of the Leaf Project given to the Foundation Year students during the fall semester of 1997. My personal description of the drawing curriculum formed part of the matrix of the Foundation Core Studies at the Ontario College of Art and Design. Research was based on the random selection of 1 8 students distributed over six of my teaching groups. The entire process included a representation of all grade levels. The intent of the research was to provide a pattern of alternative insights that could provide a more meaningful method of evaluation for visual learners in an art education setting. Visual methods of learning are indeed complex and involve the interplay of many sensory modalities of input. Using a qualitative method of research analysis, a series of queries were proposed into a structured matrix grid for seeking out possible and emerging patterns of learning. The grid provided for interrelated visual and linguistic analysis with emphasis in reflection and interconnectedness. Sensory-based modes of learning are currently being studied and discussed amongst educators as alternative approaches to learning. As patterns emerged from the research, it became apparent that a paradigm for evaluation would have to be a progressive profile of the learning that would take into account many of the different and evolving learning processes of the individual. A broader review of the student's entire development within the Foundation Year Program would have to have a shared evaluation through a cross section of representative faculty in the program. The results from the research were never intended to be conclusive. We realized from the start that sensory-based learning is a difficult process to evaluate from traditional standards used in education. The potential of such a process of inquiry permits the researcher to ask for a set of queries that might provide for a deeper form of evaluation unique to the students and their related learning environment. Only in this context can qualitative methods be used to profile their learning experiences in an expressive and meaningful manner.

Making it "click": collaborative perceptions of creative practice in art education /

Making it "Click": Collaborative Perceptions ofCreative Practice in Art Education examined the teaching practice of 6 art educators who conducted their work through the Niagara Falls Art Gallery's (NFAG) in-schools and Children's Museum programmes. These community resources service the elementary levels of participatory Public, Catholic and French schools in the Niagara Peninsula. The goal of this research was to find ways in which these teachers could explore their creative potential as art educators. The "click," a term introduced by participants indicating the coming together of all positive factors towards creativity, became the central theme behind this study. Research revealed that the effective creative process was not merely a singular phase, but rather a series of 4 processes: 1 , gathering knowledge; 2, intuitive and experiential; 3, the informal presentation of information in which creativity as a process was explored; and 4, formal presentation that took the analysis of information to a deeper, holistic level. To examine the ways in which experience and knowledge could be shared and brought together through a collaborative process, this study employed data collection that used literature research, interviews, focus group discussions, and personal journal entries. Follow-up discussions that assessed the effectiveness of action research, took place VA months after the initial meetings. It is hoped that this study might assist in creative educational practices, for myself as a member of the NFAG teaching team, for colleagues in the art programmes, art educators, and other teachers in the broader disciplines of education.

Sex Talk: A Multiple Case Study to Explore and Understand Parent-Child Sexual Health Communication in Chinese Immigrant Families

Parent-child sexual health communication can be beneficial. Many factors affect such communication in Chinese immigrant families. This qualitative study explored the influences of acculturation, parenting, and parental participation in the Raising Sexually Healthy Children Program (RSHC) on such communication. With a hermeneutic framework, the purpose was to develop understanding based on the topic, context, and researcher interpretations. Twelve interviews elicited data from six parent-child dyads, three from the RSHC. Analysis involved coding processes; data were compared repeatedly and organized into themes. Perceived personality differences between generations were confounded with cultural communicative differences. Parents used implicitness observed in Chinese culture to establish "open" communication; children expected explicitness observed in Western culture. Post- RSHC, parents perceived themselves as more open to talking about sex; children did not perceive such parental changes. Future research should include joint interviews and longitudinal program evaluation. Future practice should focus on cross-cultural communication and involving children in RSHC.

Oral French Communication in French Immersion Canadian and World Studies Classrooms: A Primer for Educators

This project presents a primer for secondary French Immersion teachers that facilitates the use of French oral communicative activities in secondary Canadian and World Studies courses. The primer supports collaborative and inclusive teaching strategies that invite students to speak and develop their oral French communication skills. The primer is divided into 2 main components: (a) Rationale for the Primer, and (b) the Strategies themselves, comprising succinct descriptions as well as potential uses and suggestions. A critical content analysis of various Ontario Ministry of Education documents was undertaken in order to explore the importance of oral communication in second-language learning in Ontario secondary schools. Furthermore, holistic and invitational education perspectives were examined in order to define the advantages of collaborative learning. Moreover, research in the stream of French Immersion studies was also referenced to frame the relevance of second-language learning and the significant role the French Immersion teacher plays. The aforementioned research contributes to the advancement of theory and practice regarding the importance of opportunities for oral French communication in secondary Canadian and World Studies courses.

The ‘Is’ of Fiction Elgin/Goodman Fictionalism : fictions in art and science

Cet essai a pour objet le rôle de la notion de fiction dans les domaines de l’art et de la science. Essentiellement, je soutiens que « fiction » dans ce contexte est « a category mistake » (concept versus genre) et je crois que cet essai peut réussir à « cuire du pain philosophique » en dévoilant une dispute verbale. Je suggère donc de clore un débat philosophique dans son intégralité. Je présente un exposé du style de fictionnalisme abordé par Catherine Z. Elgin et Nelson Goodman (que ce soit dans le contexte des arts ou des sciences, nous parvenons à la compréhension grâce à des fictions sous formes de « vérités non littérales ») et j’explore le concept de la fiction. Je soutiens que les représentations (textes descriptifs de toutes sortes, incluant les modèles) sont constituées d’éléments fictionnels et d’éléments facettés (à l’exception de la version idéale possible ou impossible, c’est-à-dire dans l’esprit de Dieu, qui n’inclurait que les facettes.) La compréhension ne peut provenir de la fiction, mais plutôt d’éléments facettés ordonnés de manière à créer une compréhension qui conduit généralement à des prédictions, des explications et des manipulations. Je définis les facettes comme ayant des caractéristiques organisées, alors que les fictions ont des caractéristiques désorganisées. La fiction dans son intégralité est donc, par définition, l’expression du néant (of nothing), ou en matière de langues idéales (mathématiques), l’expression de contradiction. Les fictions et les facettes relèvent des représentations qui sont elles-mêmes primitives. Les textes descriptifs sont donc fictionnels par degré. Les récits qui sont très fictionnels ont une certaine valeur (souvent ludique) mais contiennent toujours au moins une facette. En fin de compte, toutes les activités représentationnelles devraient être considérées irréelles, incomplètes, bien que parfois connectées à la réalité, c’est-à-dire, prises entre une description réaliste facettée et une fiction dans son intégralité.

A Mediated Presence : Uncovering Nietzsche in Art History from its Foundations to Contemporary Anglo-American Curricula

La pensée de Nietzsche a joué un rôle déterminant et récurrent dans les discours et les débats qui ont formé et continuent de façonner le domaine de l’histoire de l’art, mais aucune analyse systématique de cette question n’a encore vu le jour. L’influence de Nietzsche a été médiée par divers interlocuteurs, historiens de l’art et philosophes, qui ont encadré ces discussions, en utilisant les écrits du philosophe comme toile de fond de leurs propres idées. Ce mémoire souhaite démontrer que l’impact de Nietzsche dans le champ de l’histoire de l’art existe mais qu’il fut toujours immergé ou éclipsé, particulièrement dans le contexte anglo-américain, l’emphase étant placée sur les médiateurs de ses idées en n’avouant que très peu d’engagement direct avec son œuvre. En conséquence, son importance généalogique pour certains fondateurs de la discipline reste méconnue; sa présence réellement féconde se traduit plutôt comme une absence ou une présence masquée. En vue de démontrer ce propos, nous regardons donc le contexte nietzschéen qui travaille les écrits de certains historiens de l’art, comme Jacob Burckhardt et Aby Warburg, ou des philosophes et d’écrivains ayant marqué la discipline de l’histoire de l’art (plus particulièrement dans le cadre de l’influence de la « French Theory » sur l’histoire de l’art anglo-américaine depuis la fin des années 1970) : Martin Heidegger, Michel Foucault, Jacques Derrida, Gilles Deleuze et Georges Bataille. Nous examinons certaines voies par lesquelles ses idées ont acquis une pertinence pour l’histoire de l’art avant de proposer les raisons potentielles de leur occlusion ultérieure. Nous étudions donc l’évolution des discours multiples de l’histoire comme domaine d’étude afin de situer la contribution du philosophe et de cerner où et comment ses réflexions ont croisé celles des historiens de l’art qui ont soit élargi ou redéfini les méthodes et les structures d’analyse de leur discipline. Ensuite nous regardons « l’art » de Nietzsche en le comparant avec « l’art de l’histoire de l’art » (Preziosi 2009) afin d’évaluer si ces deux expressions peuvent se rejoindre ou s’il y a fondamentalement une incompatibilité entre les deux, laquelle pourrait justifier ou éclairer la distance entre la pensée nietzschéenne sur l’art et la discipline de l’histoire de l’art telle qu’elle s’institutionnalise au moment où le philosophe rédige son œuvre.

Managing Scholarly Communication in the Web 2.0 Environment: The Role of University Libraries

Scholarly communication over the past 10 to 15 years has gained a tremendous momentum with the advent of Internet and the World Wide Web. The web has transformed the ways by which people search, find, use and communicate information. Innovations in web technology since 2005 have brought out an array of new services and facilities and an enhanced version of the web named Web 2.0. Web 2.0 facilitates a collaborative environment in which the information users can interact with the information. Web 2.0 enables its users to create, annotate, review, share re-use and represent the information in new ways thereby optimizing the information dissemination
