Résumé :

The evolution of mobile communication systems to 3G and beyond introduces requirements for flexible, customized, and ubiquitous multimedia service provision to mobile users. One must be able to know at any given time the network status, the user location, the profiles of the various entities (users, terminals, network equipment, services) involved and the policies that are employed within the system. Namely, the system must be able to cope with a large amount of context information. The present paper focuses on location and context awareness in service provisioning and proposes a flexible and innovative model for user profiling. The innovation is based on the enrichment of common user profiling architectures to include location and other contextual attributes, so that enhanced adaptability and personalization can be achieved. For each location and context instance an associated User Profile instance is created and hence, service provisioning is adapted to the User Profile instance that better apply to the current context. The generic model, the structure and the content of this location- and context-sensitive User Profile, along with some related implementation issues, are discussed.

Résumé :

Purpose Many features constitute an adaptive system such as user model, interface specification, business functionalities and service implementation. Context awareness is an important facet of service oriented application creation dealing with the gathering, use and representation of context information. Generally, user interfaces and services communities work separately on the adaptation process and do not converge. The aim of this work is to manage the system’s functionalities and the user interface that delivers data to the relevant consumer early since the design phase until the code generation. Design/methodology/approach The authors discuss how a unified method based on a model-driven architecture for adaptive user interface and pervasive service creation eases the work of designers and developers, limits incompatibility issues and supports dynamic generation of systems adapted to different contexts of use. Findings The proposed approach is able to support a semi-automatic ubiquitous application generation with service, behavior, presentation and content adaptation. Originality/value In this paper, the authors tackle context-awareness at two levels: system functionalities and user interface generation. The authors also tackle adaptation at the specification and implementation levels.

Résumé :

A comparative evaluation of two user guides—the document traditionally used by a company and a model document designed on the basis of research results and recommendations—was carried out using a number of complementary approaches focusing on the user. The quality and suitability of these documents for the target audience were assessed in terms of content, structure, presence of certain organizational devices (such as headings) and pictures included. The results revealed that the model document was more attractive, more efficient, and better adapted to users' needs, thanks to its modular organization (being structured according to “functions”), a large number of pictures, the presence of headings, and rationalization of the vocabulary used.

Résumé :

This is the latest article in a series of research on the family-centered design concept. The theoretical context was revisited and expounded to support its usefulness in conjunction with a user-centered design approach within distinct application domains. A very important contribution is applied through the development of the instruments—website capture, a public testing platform, results processing and the Web Content Accessibility Guide 2.1 recommendation tool—to conduct unmoderated remote testing of user interfaces that corresponds to the requirements of general digitalization efforts as well as the response to current and future health risks. With this set of instruments, an experiment was conducted to address the differences in usage, and performance-wise and user-based evaluation methods, of the eDavki public tax portal, among two generations, adults and elderly citizens, and between an original and an adapted user interface that respects accessibility and other recommendations. The differences found are further discussed and are congruent to particularities that have been modified within interfaces.

Résumé :

This Note explores the future of interactive computer service provider (ICSP) liability for user-generated content under the Communications Decency Act (CDA) after Roommates.com II. Roommates.com II held that a housing website was not entitled to immunity under § 230 of the CDA from federal Fair Housing Act claims, in part because providing preselected answers to a mandatory questionnaire rendered the site an "information content provider" at least partially responsible for creation or development of answers. After examining the historical and legislative origins of ICSP immunity for user-generated content under 47 U.S. C. § 230, this Note argues that courts should generally evaluate ICSP immunity from claims arising out of both entirely and partially user-generated content on the basis of whether the ICSP is the sole information content provider Section 230's focus on which party "provides" the essential content and the statutory definition of "information content provider" support this interpretation. This Note further argues, however that Congress should amend § 230 to limit immunity in circumstances where the ICSP is an "information content provider" with respect to an objectionable housing advertisement and specifically redefine "information content provider" to include the use of ICSP created dropdown answers to ICSP required questions. This proposal is narrowly adapted to better serve the purposes of the Fair Housing Act and § 230 than the current statutory language because it defines the scope of immunity to balance the conflicting goals of the two statutes.

Résumé :

Currently, the democratization of wireless communication means coupled with the advanced technological hardware can offer portable devices that fit in the hand with a very large capacity of computation such as PDAs, mobile phones and even wireless sensors. The users' preferences, in which the document is presented, may need to be considered because the adaption of multimedia content through them is an important aspect of Quality of Service. Our research work focuses on the adaptation of multimedia documents with a strong interest on the interaction based on the user preferences. In this paper, we propose formal definitions of concepts related to the technical adaptation that selects a relevant policy in order to perform an adapted document in the situation where conflicts are detected between the heterogeneity of multimedia document properties and the user needs. We present also an architecture for adapting multimedia contents based on the preferences and we develop a user preference interface. We illustrate the proposed approach with a case study.

Résumé :

Media platforms today benefit from: (1) discretion to organize content, (2) algorithms for curating user-posted content, and (3) absolution from liability. This favorable regulatory environment results from the current legal framework, which distinguishes between intermediaries and content providers. This distinction is ill-adapted to the modern social media landscape, where platforms deploy powerful data-driven algorithms to play an increasingly active role in shaping what people see, and where users supply disconnected bits of raw content as fodder. Today's platforms have license to monetize whatever content they like, moderate if and when it aligns with their corporate objectives, and curate their content however they wish.

Résumé :

Summary Objectives: To develop a general structure for semantic image analysis that is suitable for content-based image retrieval in medical applications and an architecture for its efficient implementation. Methods: Stepwise content analysis of medical images results in six layers of information modeling incorporating medical expert knowledge (raw data layer, registered data layer, feature layer, scheme layer, object layer, knowledge layer). A reference database with 10,000 images categorized according to the image modality, orientation, body region, and biological system is used. By means of prototypes in each category, identification of objects and their geometrical or temporal relationships are handled in the object and the knowledge layer, respectively. A distributed system designed with only three core elements is implemented: (i) the central database holds program sources, processing scheme descriptions, images, features, and administrative information about the workstation cluster; (ii) the scheduler balances distributed computing; and (iii) the web server provides graphical user interfaces for data entry and retrieval, which can be easily adapted to a variety of applications for content-based image retrieval in medicine. Results: Leaving-one-out experiments were distributed by the scheduler and controlled via corresponding job lists offering transparency regarding the viewpoints of a distributed system and the user. The proposed architecture is suitable for content-based image retrieval in medical applications. It improves current picture archiving and communication systems that still rely on alphanumerical descriptions, which are insufficient for image retrieval of high recall and precision.

Résumé :

Content analysis is a well-established and widely used research method. In its early form, it was used extensively in the quantitative analysis of newspapers, and its applications later evolved to include electronic media such as radio and television. It has recently been applied to digital media, including the Internet. However, the use of content analysis in analyzing online content has been chiefly applied to static content, such as ‘static’ websites, in the early days of the Internet. Studies that involve its use in analyzing dynamic Internet content—for example, content that resides behind databases—are relatively much less common. This article is not written as a research paper per se. This article will instead discuss reflections on the efficacy of content analysis as a research method when applied to dynamic content such as DRs by using a previous study, which has applied content analysis to the dynamic content of digital repositories (DRs), as a case study. The previous study used as the basis for this article had applied content analysis to several DRs using manual counting by the researcher. In the process, several idiosyncrasies in terms of the way institutions populate their DRs with digital objects and the user metadata to facilitate discoverability of those digital objects were encountered that have introduced some ‘complication.’ This article will focus on how content analysis, as a research method, can be adapted to account for those idiosyncrasies to produce better results. This article will also identify the limitations and challenges of content analysis in dynamic online environments and offer some suggested approaches.

Résumé :

One of the biggest challenges in the development and deployment of spoken dialogue systems is the design of the spoken language generation module. This challenge arises from the need for the generator to adapt to many features of the dialogue domain, user population, and dialogue context. A promising approach is trainable generation, which uses general-purpose linguistic knowledge that is automatically adapted to the features of interest, such as the application domain, individual user, or user group. In this paper we present and evaluate a trainable sentence planner for providing restaurant information in the MATCH dialogue system. We show that trainable sentence planning can produce complex information presentations whose quality is comparable to the output of a template-based generator tuned to this domain. We also show that our method easily supports adapting the sentence planner to individuals, and that the individualized sentence planners generally perform better than models trained and tested on a population of individuals. Previous work has documented and utilized individual preferences for content selection, but to our knowledge, these results provide the first demonstration of individual preferences for sentence planning operations, affecting the content order, discourse structure and sentence structure of system responses. Finally, we evaluate the contribution of different feature sets, and show that, in our application, n-gram features often do as well as features based on higher-level linguistic representations.

Résumé :

Head-mounted displays (HMDs) increase immersion into virtual worlds. The problem is that this limits headset users' awareness of bystanders: headset users cannot attend to bystanders' presence and activities. We call this the HMD boundary. We explore how to make the HMD boundary permeable by comparing different ways of providing informal awareness cues to the headset user about bystanders. We adapted and implemented three visualization techniques (Avatar View, Radar and Presence++) that share bystanders' location and orientation with headset users. We conducted a hybrid user and simulation study with three different types of VR content (high, medium, low interactivity) with twenty participants to compare how these visualization techniques allow people to maintain an awareness of bystanders, and how they affect immersion (compared to a baseline condition). Our study reveals that a see-through avatar representation of bystanders was effective, but led to slightly reduced immersion in the VR content. Based on our findings, we discuss how future awareness visualization techniques can be designed to mitigate the reduction of immersion for the headset user.

Résumé :

Access to good nutritional health is one of the principal objectives of current society. Several e-services offer dietary advice. However, multifactorial and more individualized nutritional recommendations should be developed to recommend healthy menus according to the specific user’s needs. In this article, we present and validate a personalized nutrition system based on an application (APP) for smart devices with the capacity to offer an adaptable menu to the user. The APP was developed following a structured recommendation generation scheme, where the characteristics of the menus of 20 users were evaluated. Specific menus were generated for each user based on their preferences and nutritional requirements. These menus were evaluated by comparing their nutritional content versus the nutrient composition retrieved from dietary records. The generated menus showed great similarity to those obtained from the user dietary records. Furthermore, the generated menus showed less variability in micronutrient amounts and higher concentrations than the menus from the user records. The macronutrient deviations were also corrected in the generated menus, offering a better adaptation to the users. The presented system is a good tool for the generation of menus that are adapted to the user characteristics and a starting point to nutritional interventions.

Résumé :

This paper presents Lexical Explorer, 2 a tool that allows interactive browsing and filtering of quantitative corpus information. It further describes how this tool can be used to support linguistic work on corpora of spoken German. By using Lexical Explorer, users can analyse quantitative corpus data by interacting with frequency tables and obtaining customised word profiles of word distribution across word form variation, co-occurrences and metadata. Interaction with corpus examples of particular corpus counts is also enabled. Lexical Explorer was developed as a prototype for user-specific corpus access and is aimed at researchers of German lexicon in spoken interaction. Although Lexical Explorer was developed on the basis of two small speech corpora of the German language, the underlying principle of this tool can be easily adapted to other corpora and other user groups. Moreover, the tool can be used to gain insights into the corpus structure as well as to study and verify corpus content in a transparent and user-friendly way.

Résumé :

The present paper has introduced an innovative and efficient technique that enables user to hear the contents of text images instead of reading through them. In the current world, there is a great increase in the utilization of digital technology and multiple methods are available for the people to capture images. such images may contain important textual content that the user may need to edit or store digitally. It merges the concept of Optical Character Recognition (OCR) and Text to Speech Synthesizer (TTS). This can be done using Optical Character Recognition with the use of Tesseract OCR Engine. OCR is a branch of AI that is used in applications to recognize text from scanned documents or images. The analyzed text can also be converted to audio format to help visually impaired people hear the content that they wish to know. Text-to-Speech conversion is a method that scans and reads alphabets and numbers that are in the image using OCR technique and convert it into voices. The aim is to study and compare the multiple methods used for STT conversions and to figure out the most efficient technique that can be adapted for the conversion processes. As a result, based on review study it is found that HMM is a statistical model which is most suitable for TTS conversions.

Résumé :

Purpose – Social media is an engaging area of research that is rapidly evolving. The purpose of this paper is to focus on how corporations should effectively utilize this new media as a marketing channel. The key to any successful communication strategy is matching the message to the target audience and achieving customer engagement. Two important target audience variables were identified as crucial when determining an organization’s social media communications strategy: the level of brand relationship, and the level of category involvement. Design/methodology/approach – Depth interviews were initially employed, followed by questionnaires, and then computer assisted content analysis was performed on 723 online media articles relating to social media marketing to identify semantic and conceptual relationships. Findings – Research from both a customer and corporate perspective led to insights into how organizations can develop their social media strategies in order to transform their brand message from being perceived as a commercial source of information to a social source – the social media transformation process. Research limitations/implications – This research suggests a finer level of segmentation of social media users that will lead to content strategies adapted to fit the current levels of brand and category involvement. This could be used by organization to develop a model of best practice to achieve their social media objectives. Practical implications – It is crucial for organizations to understand how different groups of users influence, receive, curate, and interact via social media. The greater the depth of this knowledge, the greater the effectiveness of content marketing strategies developed by the corporation. Organizations that utilize social media marketing must carefully analyse the large amount of consumer information available to them, listen to consumer conversations, and determine the needs and segments that will be most receptive to different approaches. They must also accept that in a social media environment user generated content and interactive communication processes should be at the heart of successful strategy. Originality/value – To date, there has been limited analysis of how relationship and involvement factors drive social media content (Cho et al., 2014; Malthouse et al., 2013). More research is needed to understand how key user characteristics lead to content that fully utilizes the social interaction and message diffusion potential of this media. This paper introduces a hierarchy of content marketing based upon the type of relationship between the user and the organization, as well as their level of product category involvement.

Résumé :

Adaptivity is an essential quality for any mobile learning process. When learning on the move, in short time intervals, the learning process is often limited, and content needs to be adapted in order to keep the interactions with the user simple, effective, and motivating. This paper presents a model for mobile adaptive language learning, with the main goal of improving the mobile language learning process using adaptive techniques. The presented model is designed in such a way to utilize unique opportunities for delivery of learning content in authentic learning situations. In order to allow adaptivity based on several parameters, an ontological framework is presented along with a format of lightweight learning objects for content delivery. A cloud and web-service based system for adaptation is envisioned on top of the ontological framework and presented, with some implementation suggestions and possibilities discussed.

Résumé :

Network caching is a technique used to speed-up user access to frequently requested contents in complex data networks. This paper presents a two-layer overlay network caching system for content distribution. It is used to define some caching scenarios with increasing complexity, which refers to real situations, including mobile 5G connectivity. For each scenario our aim is to maximize the hit ratio, which leads to the formulation of NP-complete optimization problems. The heuristic solutions proposed are based on the theory of the maximization of monotone submodular functions under matroid constraints. After the determination of the approximation ratio of the greedy heuristic algorithms proposed, a numerical performance analysis is shown. This analysis includes a comparison with the Least-Frequently Used (LFU) eviction strategy adapted to the analyzed systems. Results show very good performance, under the hypotheses of either known or unknown popularity of contents.

Résumé :

Virtual Museum (VM) is an application of Virtual Reality (VR) technology generating realistic visualization and sensation to convince museum visitors to interact with digital content. There are many immersive VR devices that support interactive VM applications. We investigate appropriate devices for interaction within VM. We proposed a Storytelling platform to achieve device organization without modification, the story and interaction were self-adapted to the selected device. Three types of interactive content were designed on our Storytelling platform to be applied on different interaction systems: a 2D standard display, a 3D stereoscopic display and a full immersive CAVE. The results showed different performances of each system supporting VM developers to select an appropriate interaction system. The evaluation contributes to the design of content and interaction of VM development with more efficiency based on user requirements. HIGHLIGHTS Three types of interactive content were designed on our Storytelling platform to be applied on different interaction systems: A 2D standard display, a 3D stereoscopic display, and a full immersive CAVE The 2D Powerwall system with a wide range of views provides immersion. However, with two-dimensional displays, users lack depth perception Users spent more time in selection and manipulation in the 3D stereoscopic system because depth perception is added The CAVE system has user attraction or holding power, users spent more interacting time GRAPHICAL ABSTRACT

Résumé :

Abstract Persuasive argumentation depends on multiple aspects, which include not only the content of the individual arguments, but also the way they are presented. The presentation of arguments is crucial – in particular in the context of dialogical argumentation. However, the effects of different discussion styles on the listener are hard to isolate in human dialogues. In order to demonstrate and investigate various styles of argumentation, we propose a multi-agent system in which different aspects of persuasion can be modelled and investigated separately. Our system utilizes argument structures extracted from text-based reviews for which a minimal bias of the user can be assumed. The persuasive dialogue is modelled as a dialogue game for argumentation that was motivated by the objective to enable both natural and flexible interactions between the agents. In order to support a comparison of factual against affective persuasion approaches, we implemented two fundamentally different strategies for both agents: The logical policy utilizes deep Reinforcement Learning in a multi-agent setup to optimize the strategy with respect to the game formalism and the available argument. In contrast, the emotional policy selects the next move in compliance with an agent emotion that is adapted to user feedback to persuade on an emotional level. The resulting interaction is presented to the user via virtual avatars and can be rated through an intuitive interface.

Résumé :

As media technology advances, and with increasingly rapid development, there has been an unprecedented growth in the number of new media platforms emerging in China—and throughout the world—that are changing the procedures of how news is assembled and disseminated by effectively and efficiently adopting user-generated content that has injected new blood into the very nature of journalism. While essentially this is encouraging the productive use of social media platforms, it is also having an impact on users, transforming vast numbers into what are now recognized as “netizen journalists.” This leads us to inquire just how the journalistic outputs of short video platforms of such media outfits like Pear Video and Kwai are framed and also to explore how the roles of the “ordinary” users of such platforms are now defined by their participation in the actual production of news and information. This research aims to contribute to the many discussions on the above questions based on the journalistic study on three different news platforms: Xinhua News Agency’ as adopted and adapted content from Kwai, Kwai Insight, and Pear Video.

Résumé :

Purpose – The purpose of this paper is to present an adapted form of a qualitative research method, focus group interview, for use with small children and demonstrate its use in a small-scale study. Researchers often avoid direct study of children, and study them indirectly by asking adults. This was frequent before 1990s, but today, researchers increasingly discuss research with children rather than on children. Nevertheless, in research with young children it is not possible to use all research methods, therefore the authors modified and tested one. The additional research objectives, besides verification of methodology, were to determine the pre-school children’s attitudes to books, book-related places, reading. Design/methodology/approach – The adaptation of the focus group interview involved merging the content questions of the research with a story and using a toy as the storyteller. This resembled storytelling and enabled the children to directly participate by talking to the animation toy instead of the researcher. The authors tested the method on a purposive sample of 13 pre-school children aged four and five in one public kindergarten. Findings – Despite of the belief of some experts, who claim that focus group interview is not an appropriate method to explore habits or opinions of children, the authors found that adaptation of this method for the use with small children by means of storytelling and toy animation brings positive results because it enabled gathering data directly from the children. The content results show positive attitudes towards books and reading, differences in reading interests between boys and girls, daily exposure to books and reading, both in kindergarten and at home, and quite good knowledge of book-related places, especially libraries, somewhat less bookstores. Research limitations/implications – Since this is only the first attempt to use this adapted methodological approach, it is necessary that the method is tested on different user groups and in different circumstances to further validate its suitability for this user group. Regarding the content of the study, the results cannot be generalized due to non-probability purposive sampling. Originality/value – This is the first attempt to use the adapted methodological approach for researching young children. The research may serve as a beginning and incentive for further research in this area, since only high-quality results provide good modifications and adaptations of educational programmes and activities to ensure proper development of children’s reading competences and attitudes to books and reading.

Résumé :

Deaf individuals present differences compared to their hearing peers in terms of their learning profile. In addition, deaf adults seem to still be socially excluded nowadays, given that the transition from school to work is more difficult for people with hearing loss. This study aims to analyze the cognitive characteristics of deaf adults, as well as the way they learn better, for the development of an innovative and user-friendly e-learning platform, which will be adapted to the educational needs of the target group. Fifty-three deaf or hard-of-hearing adults participated in the field research for the needs of this study. According to the results, participants prefer e-learning modules with continuity in terms of the content, which offer comprehension questions during the sessions, as well as practice exercises after their completion. Furthermore, participants had positive attitudes towards the use of special graphics and explanatory videos.

Résumé :

Despite a large variety of facilities helping to either select or manipulate data from Web interfaces, it remains diffcult to provide users with relevant scientific or technical annotations for those data. Introducing such content by hand into a Web interface is a tedious job with a risk of providing in complete or inadequate content. To overcome this diffculty, we are exploring the possibility of using the names of exposed quantities to index a text corpus. This index can be used to show the most relevant text snippets in a given context. The full text can be displayed by user request and automatically scroll down to that snippet. Our approach is based on the conversion of PDF papers into machinereadable files that are indexed by a search engine. Index entries are reported as PDF annotations that are used to control the display. This workflow has been tested on the IVOA standard corpus as a proof of concept. It has then been applied to the XMM-Newtonuser guides for our catalog interface. Finally, it has been adapted to find resources within portals exposing a lot of various data collections.

Résumé :

The adoption of social networks by older adults has increased in recent years. However, many still cannot make use of social networks as these are simply not adapted to them. Through a series of direct observations, interviews, and focus groups, we identified recommendations for the design of social networks targeting seniors. Based on these, we developed a prototype for tablet devices, supporting sharing and viewing Facebook content. We then conducted a user study comparing our prototype with Facebook's native mobile application. We have found that Facebook's native application does not meet senior users concerns, like privacy and family focus, while our prototype, designed in accordance with the collected recommendations, supported relevant use cases in a usable and accessible manner.

Résumé :

Background Health information technologies (HITs) hold enormous promise for improving access to and providing better quality of mental health care. However, despite the spread of such technologies in high-income countries, these technologies have not yet been commonly adopted in low- and middle-income countries. People living in these parts of the world are at risk of experiencing physical, technological, and social health inequalities. A possible solution is to utilize the currently available HITs developed in other counties. Objective Using participatory design methodologies with Colombian end users (young people, their supportive others, and health professionals), this study aimed to conduct co-design workshops to culturally adapt a Web-based Mental Health eClinic (MHeC) for young people, perform one-on-one user-testing sessions to evaluate an alpha prototype of a Spanish version of the MHeC and adapt it to the Colombian context, and inform the development of a skeletal framework and alpha prototype for a Colombian version of the MHeC (MHeC-C). Methods This study involved the utilization of a research and development (R&D) cycle including 4 iterative phases: co-design workshops; knowledge translation; tailoring to language, culture, and place (or context); and one-on-one user-testing sessions. Results A total of 2 co-design workshops were held with 18 users—young people (n=7) and health professionals (n=11). Moreover, 10 users participated in one-on-one user-testing sessions—young people (n=5), supportive others (n=2), and health professionals (n=3). A total of 204 source documents were collected and 605 annotations were coded. A thematic analysis resulted in 6 themes (ie, opinions about the MHeC-C, Colombian context, functionality, content, user interface, and technology platforms). Participants liked the idea of having an MHeC designed and adapted for Colombian young people, and its 5 key elements were acceptable in this context (home page and triage system, self-report assessment, dashboard of results, booking and video-visit system, and personalized well-being plan). However, to be relevant in Colombia, participants stressed the need to develop additional functionality (eg, phone network backup; chat; geolocation; and integration with electronic medical records, apps, or electronic tools) as well as an adaptation of the self-report assessment. Importantly, the latter not only included language but also culture and context. Conclusions The application of an R&D cycle that also included processes for adaptation to Colombia (language, culture, and context) resulted in the development of an evidence-based, language-appropriate, culturally sensitive, and context-adapted HIT that is relevant, applicable, engaging, and usable in both the short and long term. The resultant R&D cycle allowed for the adaptation of an already available HIT (ie, MHeC) to the MHeC-C—a low-cost and scalable technology solution for low- and middle-income countries like Colombia, which has the potential to provide young people with accessible, available, affordable, and integrated mental health care at the right time.

Abstract. Here, we present a three-dimensional fluid dynamic solver that simulates debris flows as a mixture of two fluids (a Coulomb viscoplastic model of the gravel mixed with a Herschel–Bulkley representation of the fine material suspension) in combination with an additional unmixed phase representing the air and the free surface. We link all rheological parameters to the material composition, i.e., to water content, clay content, and mineral composition, content of sand and gravel, and the gravel's friction angle; the user must specify only two free model parameters. The volume-of-fluid (VoF) approach is used to combine the mixed phase and the air phase into a single cell-averaged Navier–Stokes equation for incompressible flow, based on code adapted from standard solvers of the open-source CFD software OpenFOAM. This effectively single-phase mixture VoF method saves computational costs compared to the more sophisticated drag-force-based multiphase models. Thus, complex three-dimensional flow structures can be simulated while accounting for the pressure- and shear-rate-dependent rheology.

Résumé :

Background: Pediatric palliative care (PPC) is characterized by years of multisectoral and multi-professional care. Sharing information between PPC professionals is, therefore, essential for quality care. The evidence shows that electronic cross-facility health records (ECHRs) provide useful support in this context. To our knowledge, no ECHRs have been developed through a user-centered approach for this specific setting in Germany. Methods: Guided by design thinking, first, qualitative interviews were conducted to assess the needs of PPC professionals. Second, the elicited needs were specified in focus groups (FGs). Based on the needs stated in the interviews, prototypes of the ECHR were developed and discussed in the FGs. The indicated needs were supplemented and specified in an iterative process. The prototypes were further adapted according to these results. The unified theory of acceptance and use of technology was the basic model in the evaluation of needs. Results: Across seven main categories, past and current medication, emergency view, and messaging functions were identified as the participants’ desired core components of an ECHR. Utilizing design thinking facilitated the explicit articulation of user needs. Conclusions: Developing an ECHR with the content identified would allow for real-time data during emergencies, tracking what other PPC professionals have done, and making the applied treatments visible to others. This would offer a broader picture of the complex conditions common to PPC.

Résumé :

One of the many ways through which the universities can communicate with students is through their website, which is considered as the face of the organization. It also represents the organization as a whole, its culture, value and vision. The current study aimed to check the usability of Gujarat Technological University’s website from students’ perspective and to find its association with satisfaction. The current study tried to address the gap in the literature, wherein in the Indian context, the majority studies were conducted in the context of library website only. The current study has adopted a quantitative approach, where a single cross-sectional research design has been used with convenience sampling. The present study had adapted the Website Usability Evaluation (WEBUSE) scale. A total of 577 students from the fields of management, computer science, and engineering have responded to the structured questionnaire. The structural equation model of the study revealed that all the four dimensions of website usability were positively associated with satisfaction, whereas content, organization and readability criterion had the most influence on satisfaction followed by user interface design, performance and effectiveness and navigation and links. The study strongly recommends the university to maintain up-to-date content, organize it well and it should be readable for the students in order to maximize the satisfaction with the website.

Résumé :

This paper investigates the impact of post-purchase user generated content (UGC) and traditional reference groups on the purchase intentions for electronic products (e-products) among young consumers in Jordan. To achieve this, a descriptive methodology was adapted, with a quantitative approach and survey strategy utilizing a five-point Likert scale questionnaire distributed to 450 university and college students in Jordan. 400 filtered and screened copies underwent statistical analyses. SPSS version 21 was utilized to describe and analyze the data. The results revealed a strong impact of post-purchase UGC on purchase intentions of e-products among young consumers. The results also revealed that traditional reference groups have a lower significant impact on the purchase intentions of young consumers, indicating that young consumers rely on online communities more than they rely on family, friends, colleagues, and other social organizations. The findings are discussed with a view to their implications, with recommendations for future research.

Résumé :

Web-based digital interventions may play a central role for health promoting strategies in the first “1000 days”, from conception through the first 2 years of life. We developed a web platform providing evidence-based recommendations in the first 1000 days through short videos, and we studied engagement by users from preconception through parenthood in the second year of life. We described the access to videos by topic and used a multilevel model to explore the user characteristics associated with access to the video recommendations. Overall, breastfeeding, physical activity and nutrition were the most popular topics (normalized views: 89.2%, 87.2% and 86.4% respectively), while content on paternal health and smoking and alcohol was less engaging (37.3% and 42.0%). Nutrition content was the most viewed in the preconception period and during the first two trimesters of pregnancy. Nutrition and breastfeeding were also the most popular topics for users with children less than 2 years old. Higher levels of health literacy were associated only with child health content. The study findings indicate that digital strategies should be adapted according to the time period in the first 1000 days. Alternative digital promotion strategies for the less engaging topics should be considered.

Purpose – This is an exciting time for catalog and metadata librarians. A number of new tools and trends are now a part of our daily work. From the new content standard, Resource Description and Access, to the rise of opportunities with data management and digital humanities, catalog and metadata librarians are being asked to change how they work. They are now interacting with colleagues and their communities in ways that go beyond description and subject analysis. In fact, they are seeking ways to respond to these new users’ needs in the form of innovative services, new ways of thinking and doing business. However, how do catalog and metadata librarians meet these challenges? What is important to learn when faced with new trends and increased users’ demands? Design/methodology/approach – An overview of what the UCL are doing to meet changing trends and user needs. Findings – Though there is no one size fits all, the UCL catalog and metadata librarians have decided to meet the challenge of new tools and changing user demands by engaging in learning, teaching and networking. Originality/value – The techniques adopted by the UCL can be adapted to fit other institutions around the world.

Résumé :

Objective: We investigated adapting the interaction style of intelligent tutoring system (ITS) feedback based on human–automation etiquette strategies. Background: Most ITSs adapt the content difficulty level, adapt the feedback timing, or provide extra content when they detect cognitive or affective decrements. Our previous work demonstrated that changing the interaction style via different feedback etiquette strategies has differential effects on students’ motivation, confidence, satisfaction, and performance. The best etiquette strategy was also determined by user frustration. Method: Based on these findings, a rule set was developed that systemically selected the proper etiquette strategy to address one of four learning factors (motivation, confidence, satisfaction, and performance) under two different levels of user frustration. We explored whether etiquette strategy selection based on this rule set (systematic) or random changes in etiquette strategy for a given level of frustration affected the four learning factors. Participants solved mathematics problems under different frustration conditions with feedback that adapted dynamic changes in etiquette strategies either systematically or randomly. Results: The results demonstrated that feedback with etiquette strategies chosen systematically via the rule set could selectively target and improve motivation, confidence, satisfaction, and performance more than changing etiquette strategies randomly. The systematic adaptation was effective no matter the level of frustration for the participant. Conclusion: If computer tutors can vary the interaction style to effectively mitigate negative emotions, then ITS designers would have one more mechanism in which to design affect-aware adaptations that provide the proper responses in situations where human emotions affect the ability to learn.

Résumé :

New application requirements like “real-time” and “multimedia” is formed gradually with the trend of convergence of the Internet, web 2.0 and telecommunication network. In the era of Internet and web 2.0, users hope to communicate under multimedia context, to which Weibo and other SNS have adapted a lot. Users of web community wish to demand real-time videos and share with others instantly. Network convergence, IMS (IP Multimedia Subsystems) and VoLTE deployment all make the telecom operators long for new multimedia services. In terms of the users, they want to receive multimedia service anywhere and anytime, while the service and content providers also want to build a barrier-free channel for offering and distributing service. Taking the related technologies and user requirements into consideration, a multimedia sharing service and application is proposed and demonstrated in this paper. The system technique schema and deployment solution could help understanding the multimedia sharing service framework and modules in the convergence network. Samples of signal flows and processes are demonstrated in 3 typical application scenarios. Business application, product perspective and business model analysis shows the great market potential of this new multimedia sharing application and service in the near future.

Résumé :

The use of information technology in the field of cultural heritage makes it possible to involve more and more people in the promotion of cultural heritage, fostering social, cultural, economic and community growth. This work stems from the interest in using Virtual Reality (VR) in the field of cultural heritage, creating a tour of the city of Bari that tells its evolution over the years. To this end, a low-cost VR360 application has been developed which, by means of a cardboard, allows the user to experience a virtual journey through time. It tells the story of the city, focusing on its urban expansion and the evolution of its architectural styles, influenced by various dominations over the centuries, up to the current state. The virtual environment was created from spherical images of the city, captured through 360° cameras and enriched with various types of information content. The user experience was assessed by means of a questionnaire derived from previous work that was generalised and adapted to the considered scenario: the results showed a very good level of satisfaction, usability, engagement, immersion and sense of presence; the highest score was obtained for the visual quality of the images of the virtual environment.

Résumé :

The aim of this study was to develop, refine, and assess the usability of pictorial action instructions (PAI) in training low-literacy individuals to build a basic humanitarian engineering project. Health in low- and middle-income countries is disproportionately affected by environmental hazards, often mitigated by such projects, but widespread literacy deficits often necessitate literacy-adapted materials for training. Project-specific PAI were developed, refined, and tested, with the intent of later testing them abroad. Development was based on best practice guidelines for illustrations and easy-to-understand text. The PAI were then reviewed by literacy specialists for content and formatting. Next, a feasibility study was conducted in Utah with low-literacy immigrants who were trained to use the PAI and provided with tools and materials to individually construct the project. Usability metrics gathered included construction efficiency and effectiveness, user satisfaction, and self-efficacy. Effectiveness was 100% and user satisfaction and self-efficacy were both high. Participants provided feedback to improve the PAI’s clarity by changing item proximity and combining or separating steps, and revisions were made. In future PAI development, it would be beneficial to include low-literacy individuals when making the initial sketches to enhance sequence clarity before finalizing the illustrations.

School is one of the formal education facilities that must be able to provide the best services or facilities for students and also for parents. One of the right ways is to use information technology, namely accessing academic values through websites. The specific objective of this research is to produce an academic information system based on Wordpress Content Management System (CMS) that can be used by SMPN 17 Marusu in Maros Regency. The current website-based academic information system is made using a complex programming language and requires special skills to create the website. Wordpress is a platform for creating websites instantly. In this study, the information system was built using the prototype method so that it can be adapted to user needs. The resulting software is presented to the user, starting from the requirements analysis, design to implementation stage, and users are given the opportunity to provide input so that the resulting software really fits the user's needs. The prototype method consists of several stages, namely, requirements analysis, system analysis, system design, system testing, and system implementation. The design stage includes interface design, front end and back end using WordPress CMS. With this school website, it is hoped that it can help government programs in improving school performance and productivity.

Résumé :

<p>Nowadays, intelligent e-learning systems which can adapt to learner's needs and preferences, became very popular. Many studies have demonstrated that such systems can increase the eects of learning. However, providing adaptability requires consideration of many factors. The main problems concern user modeling and personalization, collaborative learning, determining and modifying learning senarios, analyzing learner's learning styles. Determining the optimal learning scenario adapted to students' needs is very important part of an e-learning system. According to psychological research, learning path should follow the students' needs, such as (i.a.): content, level of diculty or presentation version. Optimal learning path can allow for easier and faster gaining of knowledge. In this paper an overview of methods for recommending learning material is presented. Moreover, a method for determining a learning scenario in Intelligent Tutoring Systems is proposed. For this purpose, an Analytic Hierarchy Process (AHP) method is used.</p>

Résumé :

Abstract User satisfaction assessments are integral to demonstrating intervention efficacy. Towards that end, older participants across the Aging Strong 2020 suite of offerings participated in semi-structured interviews (n = 248) to provide feedback about their experiences in the program and resulting satisfaction. Overall, most participants were satisfied with the Aging Strong 2020 interventions and reported gaining new skills, tools, or coping strategies. Participants endorsed program features that facilitated social interaction, community building, and social support. Program content specifically adapted for older adults and appropriate life stage concerns and/or areas of interest were considered especially helpful. Results demonstrate that the current test and learn model offers an opportunity for participant feedback to refine and improve future iterations of project offerings. Participant feedback led to key improvements in subsequent versions of the Aging Strong 2020 programs and their contributions to successful aging among older adults.

Many current (online) help systems fail because users refuse to use them or, even if they do so, they do not perceive them as helpful. There is an obvious gap between the intentions of the help content authors and the achievement of objectives concerning the perceived usefulness by help users. Problems may be divided into psychological and implementation issues. On the psychological side users are often seriously challenged with understanding the instructions given by the system, which usually is not adequately adapted to user's prior knowledge or the vocabulary of a lay person. This problem of expert-lay communication is strengthened by the implementation problem of missing feedback channels. As a result, help systems do often leave users in isolation with their problems. The current article aims to address these issues by presenting an information architecture for an online help system which addresses aspects of communication between authors and users. The approach combines earlier models of design patterns with features for user contribution from social software and design principles in multimedia learning.

Résumé :

Background PTSD Coach Australia is an app for serving and ex-serving defense members and was adapted for the Australian context in 2013 from PTSD Coach, which was created in the United States. Objective This study aimed to provide a user-centered evaluation of the app from the perspective of serving and ex-serving members of the Australian Defence Force. Methods Qualitative data were collected in response to questions to participants in 1 of 5 workshops (n=29) or in telephone interviews (n=24). Quantitative data were collected using the user version of Mobile Apps Rating Scale (uMARS). Results Analysis of the qualitative data demonstrated mixed support for the app. While some people found it extremely useful, especially as an adjunct to therapy, others pointed out limitations and cautioned against the app potentially triggering symptoms in people with PTSD. This perceived risk was usually found to stem from frustration with the app’s functionality rather than its content. Participants spoke about the helpful and unhelpful aspects of the app and barriers to its use and made suggestions for improvement. Many participants encouraged its continued use and highlighted the need for it to be promoted more broadly, as many were not aware of it until they were invited to participate in this research. Conclusions PTSD Coach Australia was seen in a positive light by some participants, but others thought it had too much text and the potential to trigger a traumatic response in users with PTSD. A need to update the app was also a common comment as was the need to increase awareness of the app’s existence.

Résumé :

summary We conducted a qualitative evaluation of the introduction of a telenursing service. The service used an analogue videophone linked with a physiological monitoring device, which allowed the transmission of data between the patient's home and the hospital. A researcher kept a detailed diary of day-to-day activity for the first year of the project. Computer software for qualitative data analysis was used to code the text and the analysis followed the principles of constant comparison. The diary entries documented how the commercially available equipment was adapted to suit the organization and content of the nurses’ work. The nurses made a number of suggestions to improve the user-friendliness of the equipment. The technology, the existing home care service (the comparison arm of the study) and the randomized controlled trial itself all underwent continuous change. The traditionalrandomized control design of trial has limitations in this situation, and there is a need for more realistic trial designs.

Résumé :

Interactive web-based questions were developed for students to review subject matter learned in an online plant propagation course. Articulate Storyline software was used to build nearly 250 review questions with five different testing styles to ascertain proficiency in subject areas, including the biology of propagation, the propagation environment, seed propagation, vegetative propagation, micropropagation, and cell culture. Questions were arranged to correspond to the supporting textbook chapters in Hartmann and Kester’s Plant propagation: Principles and practices, ninth edition. These are open access and available to instructors and students worldwide. Users received immediate feedback for each question answered correctly or incorrectly. The system remembers where one leaves off, which enables starting and stopping multiple times within a chapter. Means of pre- and posttest responses to nine content knowledge items showed that students perceived a significant content knowledge gain in the course. These online interactive reviews can be adapted easily to other courses in a variety of fields, including horticulture, botany, systematics, and biology. They can also be expanded to overlay multiple objects and trigger events based on user response. Since inception, the website hosting these online reviews averaged 156 unique visitors per month. Students have reported this to be a useful tool to prepare them for course exams.
