There has been little attention given to examining innovation under the conditions in which community sport organizations (CSO) operate. In this case study, process one CSO undertook a technological is explored. The purpose of research was classify determinants that contributed process, and identify at particular stages those were critical. Interviews focus groups with key stakeholders conducted during process. Observations made important points implementation innovation. Leadership...
Research question: The purpose of this investigation is threefold. First, as indications the acquisition and creative use knowledge, study explores extent to which community sport organizations (CSOs) are pursuing innovations. Second, these innovations categorized based on their form, type, magnitude. Third, role that context plays in CSOs examined.Research methods: Semi-structured telephone interviews were conducted with 42 volunteer presidents (or designates) CSOs, curling, soccer,...
The Royal Canadian Mounted Police (RCMP), like all public safety personnel (PSP), are frequently exposed to potentially psychologically traumatic events that contribute posttraumatic stress injuries (PTSI). Addressing PTSI is impeded by the limited available research. In this protocol paper, we describe RCMP Study, part of concerted efforts reduce improving access evidence-based assessments, treatments and training as well participant recruitment Study developments date. has been designed...
Abstract Position information is an important aspect of a mobile device’s context. While GPS widely used to provide location information, it does not work well indoors. Wi-Fi network infrastructure found in many public facilities and can be for indoor positioning. In addition, the ubiquity Wi-Fi-capable devices makes this approach especially cost-effective. recent years, “folksonomy”-like systems such as Wikipedia or Delicious Social Bookmarking have achieved huge successes. User...
Purpose – Due to the size and velocity at which user generated content is created on social media services such as Twitter, analysts are often limited by need pre-determine specific topics themes they wish follow. Visual analytics software may be used support interactive discovery of emergent themes. The paper aims discuss these issues. Design/methodology/approach Tweets collected from live Twitter stream matching a user’s query stored in database, classified based their sentiment....
Our study examined and compared the type, process, conditions, consequences of radical incremental innovations in community sport organizations (CSOs), which are a type nonprofit membership association. Interviews were conducted with president (or representative) 14 CSOs engaged both innovations. Radical reported to be mostly technical (but also administrative), undertaken goal club growth enhancing management, adopted further adapted from outside organization, influenced by culture...
Abstract While the search interfaces used by common academic digital libraries provide easy access to a wealth of peer‐reviewed literature, their little support for exploratory browsing. When faced with complex task (such as one that requires knowledge discovery), browsing is an important first step in process. To more effectively browsing, we have designed and implemented novel library interface (KLink Search) two new features: visually linked keywords interactive workspace. study potential...
The primary focus of Web information retrieval support systems (WIRSS) are to address the aspects search that consider specific needs and goals individuals conducting searches. WIRSS moves beyond traditional automated searching within digital collections, applying intelligent methods Web-based technologies assist users in specifying their needs, evaluating exploring results, managing they find. goal this paper is provide an overview some key issues, challenges, opportunities research.
In this article, we advocate the development of underexplored collaborations between leisure and computer science scholars. Focus is placed on exploring understanding digital consumer behaviors experiences potential for social justice research in contexts media eSport. Leisure scholars stand to benefit from leveraging technological expertise considering different theories engagement with technology. Opportunities collaboration are described while recognizing mutual benefits all involved...
While the information retrieval techniques used by web search engines have improved substantially over years, results continued to be represented in a simple list-based format. Although this representation makes it easy evaluate single document, does not support users broader tasks of manipulating results, comparing documents, or finding set relevant documents. HotMap provides compact visual at two levels detail, and supports interactive exploration results. User studies shown that can...
Users of traditional Web search engines commonly find it difficult to evaluate the results their searches. We suggest use information visualization and interactive visual manipulation as methods for improving ability users a search. In this paper, we present user study that compared interface provided by Google two systems have developed: HotMap Concept Highlighter. found were able perform searches faster with HotMap, more relevant documents Highlighter, generally ranked these interfaces...
Although association rule mining is an important pattern recognition and data analysis technique, extracting finding significant rules from a large collection has always been challenging.The ability of information visualization to enable users gain understanding high dimensional large-scale can play major role in the exploration, identification, interpretation rules.In this paper, we propose method that provides multiple views rules, linked together through filtering mechanism.A visual...
Academic digital library searchers often employ exploratory search strategies when faced with the complex task of finding academic literature on a topic that is new to them. Unfortunately, interfaces employed by libraries provide little support for browsing, which critical first step in search. To address this shortcoming, we have designed and implemented novel interface (KLink Search) two features: visually linked keywords an interactive workspace. Here, present preliminary analysis data...
Keywords contain important contextual information about search results within academic digital library interfaces. However, such tends to be underutilized modern interface designs. In prior work, methods for visually linking keywords between have been proposed and studied. this research, we analyze the design space propose a new approach that aggregates over all items on engine page (SERP), them back their source result. We created interactive static versions of both interfaces, conducted...
It is common for Web searchers to have difficulties crafting queries fulfil their information needs. Even when they provide a good query, users often find it challenging evaluate the results of searches. Sources these problems include lack support query refinement, and static nature list-based representations search results. To address issues, we developed WordBars, an interactive tool retrieval. WordBars visually represents frequencies terms found in first 100 document surrogates returned...
The analysis of large movement datasets is a challenging task, because their size and spatial complexity. This paper presents an interactive geovisual analytics approach named Hybrid Spatio-Temporal Filtering that integrates filtering multiple characteristics, representations the data, coordinated views to enable analysts focus on patterns are interest. In particular, we propose novel technique combines fractal dimension velocity paths filter out uninteresting records through iterative...
As search tasks move beyond targeted and into the domain of complex search, a substantial cognitive burden is placed on searcher to craft refine their queries, evaluate explore among results, ultimately make use what found. In such cases, information visualization techniques may be leveraged enable searchers perceive, interpret, sense available throughout process. This tutorial will establish fundamental principles theories visualization, explain how can support interactive retrieval, survey...
An important contribution in the development of interactive information retrieval as a research discipline has been specification seeking models. A variety such models have documented, some which apply generally to broad set search settings, and others are specific settings academic search. Within domain search, it is unclear what extent searchers employ strategies specified when faced with different types needs (ranging from fact verification knowledge discovery). Using an online...
