High-speed idea filtering with the bag of lemons
No full textOpen innovation platforms (web sites where crowds post ideas in a shared space) enable us to elicit huge volumes of potentially valuable solutions for problems we care about, but identifying the best ideas in these collections can be prohibitively expensive and time-consuming. This paper presents an approach, called the “bag of lemons”, which enables crowd to filter ideas with accuracy superior to conventional (Likert scale) rating approaches, but in only a fraction of the time. The key insight behind this approach is that crowds are much better at eliminating bad ideas than at identifying good ones.

Keeping language in place: from Dene transitional-immersion at school to a local Dene teacher education program
No full textDene Sųłiné, a Dene (Athabaskan) language spoken in North-western Saskatchewan, remains the dominant language in the communities of La Loche and Clearwater River Dene Nation. Out of a total population of 3,400, more than 90% speak Dene. Until recently, children who entered the school system were dominant Dene speakers. Responding to this situation, the Clearwater River Dene School introduced a transitional-immersion program in 2007. In grades K-3 Dene is used as main medium of instruction, with a gradual phasing in of English-taught classes. Grades 4-12 are primarily taught in English, with complementing Dene language classes. This set-up proved to be highly successful, as evidenced in a dramatic increase at comparative provincial testing results. Such programs are possible only because of fully trained teachers who are also fluent speakers of the Aboriginal language. The number of such individuals remains low, nowhere near enough to fill the demand in schools across Canada. Language teachers have the potential to contribute directly to the maintenance and revitalization efforts within their linguistic community and beyond. While the transitional immersion program in Clearwater River continues to benefit from the presence of several local teachers fluent in Dene, the need for additional Dene teachers and teaching resources became apparent especially in two areas: as high school teachers, and as a response to the increasing shift to English especially with the under 10-yr olds. Due to the remoteness of the community, many strong language speakers are reluctant to leave their home to train at a university in an urban centre. In a newly established cooperation between the Clearwater River Dene Nation, the First Nations University of Canada, and the Northern Lights School District, an innovative Dene Teacher Education Program (DTEP) was implemented in 2016. This program is offered on the Clearwater River Dene Nation and thus enables a large cohort of students to access a full 4-year Education program. Within the four-year B.Ed. program two unique aspects will emerge. The first involves the students’ practicum experience that will involve the students and current teaching staff of Clearwater River Dene School Transitional Immersion program. Secondly as Dene Sųłiné is a land-based culture and language, the focus throughout will be to relate all learning outcomes from course work to the context of a land-based education
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
A handbook-based methodology for redesigning business processes
No full textThis paper presents a structured methodology, based on the use of a Handbook of process models, for redesigning business processes. The methodology is illustrated using examples from the agri‐food supply chain domain. We discuss the strengths and weaknesses of this approach, and identify avenues for further work
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
From problems to protocols: Towards a negotiation handbook
No full textAutomated negotiation protocols represent a potentially powerful tool for problem solving in decision support systems involving participants with conflicting interests. However, the effectiveness of negotiation approaches depends greatly on the negotiation problem under consideration. Since there is no one negotiation protocol that clearly outperforms all others in all scenarios, we need to be able to decide which protocol is most suited for each particular problem. The goal of our work is to meet this challenge by defining a “negotiation handbook”, that is, a collection of design rules which allow us, given a particular negotiation problem, to choose the most appropriate protocol to address it. This paper describes our progress towards this goal, including a tool for generating a wide range of negotiation scenarios, a set of high-level metrics for characterizing how negotiation scenarios differ, a testbed environment for evaluating protocol performance with different scenarios, and a community repository which allows us to systematically record and analyze protocol performance data.

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
