From outreach to engaged placemaking: understanding public land-grant university involvement with tourism planning and development
No full textPublic land-grant universities (PLGUs) have been mandated for nearly a century to fulfill research, teaching, and public service missions by advancing scholarly inquiry that benefits broader society, by ensuring educational access to a broad citizenry, and by providing direct assistance to communities primarily through agricultural cooperative extension services. With the advent of a global service-based economy in recent decades, PLGUs have become involved with tourism planning and development efforts in their communities as forms of education and public service through academic programs and cooperative extension tourism, as well as through conference and event services and through campus-based visitor information centers. PLGU involvement with tourism planning and development signals a trend towards placemaking that coincides with the national university-community engagement movement. This exploratory analysis begins to clarify PLGU involvement with tourism planning and development as an emergent form of university-community engagement. The study finds that predominantly elite PLGUs are promoting their involvement with tourism planning and development as community engagement, thereby advancing themselves as powerful placemakers that help to make their communities more competitive destinations in regional and national place hierarchies. As a consequence, PLGUs that appear to lack capacity to compete in this innovative approach to community engagement also appear to lack placemaking power in their communities. Ultimately, the study asserts that the adoption of community-based tourism engagement marketing strategies among elite PLGUs creates a new playing field on which lower capacity PLGUs and their communities are disadvantaged to compete. Ironically, this practice reinforces the very class and power structures that the university-community engagement movement seeks to address. Using primarily grounded theory, institutional ethnography, and case study methodological approaches, the study identifies and characterizes levels of tourism planning and development capacity among PLGUs on national and regional scales. The study lays groundwork for further research on PLGU tourism planning and development as both a potentially beneficial and potentially disempowering form of university-community engagement.Ph.

Metodo e dispositivo per la valutazione di proprietà termofisiche del terreno e della resistenza termica effettiva di sonde geotermiche
No full textSINTESI DELL’INVENZIONE.
La presente invenzione ha per oggetto un metodo per la valutazione di proprietà termofisiche del terreno e della resistenza termica effettiva di sonde geotermiche di sonde geotermiche verticali utilizzate negli impianti a pompa di calore geotermica, utilizzante tecnica di sovrapposizione degli effetti e funzione di trasferimento SLI per analisi di esperimenti a carico termico variabile nel tempo.
Il Metodo, comprende i seguenti passi:
a) circolazione di un fluido termovettore in un circuito idraulico chiuso comprendente almeno una sonda geotermica;
b) cessione o sottrazione di flusso termico al fluido termovettore in mandata alla sonda geotermica;
c) misurazione delle temperature del fluido termovettore in mandata e in ritorno rispetto alla sonda geotermica;
d) calcolo di valori di conducibilità termica del terreno e di resistenza termica della sonda geotermica sulla base di un’analisi dell’andamento nel tempo delle temperature rilevate, utilizzando opportuno modello matematico per la corretta interpretazione degli effetti dei carichi termici variabili nel tempo sui risultati della misura
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
