Mid-air interaction involves touchless manipulations of digital content or remote devices, based on sensor tracking of body movements and gestures. There are no established, universal gesture vocabularies for mid-air interactions with digital content or remote devices based on sensor tracking of body movements and gestures. On the contrary, it is widely acknowledged that the identification of appropriate gestures depends on the context of use, thus the identification of mid-air gestures is an important design decision. The method of gesture elicitation is increasingly applied by designers to help them identify appropriate gesture sets for mid-air applications. This paper presents a review of elicitation studies in mid-air interaction based on a selected set of 47 papers published within 2011–2018. It reports on: (1) the application domains of mid-air interactions examined; (2) the level of technological maturity of systems at hand; (3) the gesture elicitation procedure and its variations; (4) the appropriateness criteria for a gesture; (5) participants number and profile; (6) user evaluation methods (of the gesture vocabulary); (7) data analysis and related metrics. This paper confirms that the elicitation method has been applied extensively but with variability and some ambiguity and discusses under-explored research questions and potential improvements of related research.

The number of cyberattacks on organizations is growing. To increase cyber resilience, organizations need to obtain foresight to anticipate cybersecurity vulnerabilities, developments, and potential threats. This paper describes a tool that combines state of the art text mining and information retrieval techniques to explore the opportunities of using these techniques in the cybersecurity domain. Our tool, the Horizon Scanner, can scrape and store data from websites, blogs and PDF articles, and search a database based on a user query, show textual entities in a graph, and provide and visualize potential trends. The aim of the Horizon Scanner is to help experts explore relevant data sources for potential threats and trends and to speed up the process of foresight. In a requirements session and user evaluation of the tool with cyber experts from the Dutch Defense Cyber Command, we explored whether the Horizon Scanner tool has the potential to fulfill its aim in the cybersecurity domain. Although the overall evaluation of the tool was not as good as expected, some aspects of the tool were found to have added value, providing us with valuable insights into how to design decision support for forecasting analysts.

Despite the availability of millions of information resources on the internet, the Arabic digital content represents a relatively small percentage compared with the information available in other languages. The size of Arabic content, the lack of an adequate number of Arabic databases that organize this content and make it available to the Arab reader, and the lack of novelty and originality are the main issues that feature the Arabic content on the internet. The aim of the current study is to clarify the Arab scholars’ perception regarding the quality, reliability, and suitability of Arabic digital content that is available on the internet. A quantitative approach was adopted in this study in order to answer the research questions. A questionnaire was distributed online among a sample of Arab scholars to determine the quality and reliability of the Arabic digital content. Moreover, the questionnaire tried to identify the extent to which the current Arabic digital content meets the growing information needs, to identify the Arab scholars’ uses of Arabic content, and to discover the criteria that determine the digital content suitability. The findings of this study revealed that Arab scholars believe that Arabic digital content is weak and there is a lack of originality. In addition, the results indicated that Arabic digital content on the internet does not satisfy the scholars' needs which enforce them to use English information resources to compensates for the lack of Arabic resources. The study recommended the necessity of establishing mechanisms to support Arabic digital content and increase the academic institutions' role in enhancing Arabic digital content by encouraging and supporting scholarly research in the Arabic language.

Kindergartens are one of the most vulnerable areas against the earthquake, because of the age of users and lack of training them to seek shelter in this event. Create safe shelters for children in kindergartens, is one of the most important design requirements that is ignored in the construction of this important space. Since most of the kindergartens are spaces that converted from another usage, so some solutions should be considered for kindergartens status quo to be safe against earthquake. The purpose of this search is establishing practical guidelines for the safety of child care spaces, as one of the most dangerous places against earthquake. The research questions that arise are: 1) how can make safe the kindergartens againstearthquake? 2) Can kindergartens be secure against earthquakes for users of these spaces, children, withuse of furniture? To answer these questions,first the idea of the triangle of life, have studied and analyzed the relationship between furniture and it. The research method used in this study, is library method according the study of the available samples. The results show that we can get maximum safety against this natural disaster rely on the idea of the triangle of life and using specific materials of furniture in kindergartens with training the children along playing haw to seek shelter during an earthquake within each class, and in the nearest possible space.

The study, which examines the position of the main idea in interior design and the development process of the main idea, aims to emphasize the importance of the main idea in terms of the space design. The main idea is an important design decision that can be defined as the core of the design, guides the designer at every stage of the design process. There are some data that need to be analyzed at the beginning of the design process. Various notions are reached based on these data, which are called as main idea components within the scope of the study. With the determination of the notions, the main idea is developed as a solution proposal to the design problem. Subsequently, the main idea is transferred to the design by adopting design approaches focusing on different aspects. The process diagram of transferring the main idea to the design is prepared with the data obtained in the theoretical parts of the study, which main idea components, design approaches and the development process of the main idea are examined. The validity of this diagram was questioned in a field study conducted with the students of Çukurova University, Department of Interior Architecture. The design processes in the analyzed applications were evaluated in accordance with this diagram, and in the light of the findings, the study was concluded with suggestions for future studies on the subject.

This paper is concerned with the development of digital humanities infrastructure – tools and resources which make using existing e-content easier to discover, utilise and embed in teaching and research. The past development of digital content in the humanities (in the United Kingdom) is considered with its resource-focused approach, as are current barriers facing digital humanities as a discipline. Existing impacts from e-infrastructure are discussed, based largely on the authors’ own discrete or collaborative projects. This paper argues that we need to consider further how digital resources are actually used, and the ways in which future digital resources might enable new types of research questions to be asked. It considers the potential for such enabling resources to advance digital humanities significantly in the near future.

Three experiments (N = 550) examined the effect of an interval construction elicitation method used in several expert elicitation studies on judgment accuracy. Participants made judgments about topics that were either searchable or unsearchable online using one of two order variations of the interval construction procedure. One group of participants provided their best judgment (one step) prior to constructing an interval (i.e., lower bound, upper bound, and a confidence rating that the correct value fell in the range provided), whereas another group of participants provided their best judgment last, after the three-step confidence interval was constructed. Theoverall effect of this elicitation method was not significant in 8 out of 9 univariate tests. Moreover, the calibration of confidence intervals also was not affected by elicitation order. The findings warrant skepticism regarding the benefit of prior confidence interval construction forimproving judgment accuracy.

The beauty of synchronized dancing lies in the synchronization of body movements among multiple dancers. While dancers utilize camera recordings for their practice, standard video interfaces do not efficiently support their activities of identifying segments where they are not well synchronized. This thus fails to close a tight loop of an iterative practice process (i.e., capturing a practice, reviewing the video, and practicing again). We present SyncUp, a system that provides multiple interactive visualizations to support the practice of synchronized dancing and liberate users from manual inspection of recorded practice videos. By analyzing videos uploaded by users, SyncUp quantifies two aspects of synchronization in dancing: pose similarity among multiple dancers and temporal alignment of their movements. The system then highlights which body parts and which portions of the dance routine require further practice to achieve better synchronization. The results of our system evaluations show that our pose similarity estimation and temporal alignment predictions were correlated well with human ratings. Participants in our qualitative user evaluation expressed the benefits and its potential use of SyncUp, confirming that it would enable quick iterative practice.

Abstract There are ∼7000 rare diseases affecting 30 000 000 individuals in the U.S.A. 95% of these rare diseases do not have a single Food and Drug Administration-approved therapy. Relatively, limited progress has been made to develop new or repurpose existing therapies for these disorders, in part because traditional funding models are not as effective when applied to rare diseases. Due to the suboptimal research infrastructure and treatment options for Castleman disease, the Castleman Disease Collaborative Network (CDCN), founded in 2012, spearheaded a novel strategy for advancing biomedical research, the ‘Collaborative Network Approach’. At its heart, the Collaborative Network Approach leverages and integrates the entire community of stakeholders — patients, physicians and researchers — to identify and prioritize high-impact research questions. It then recruits the most qualified researchers to conduct these studies. In parallel, patients are empowered to fight back by supporting research through fundraising and providing their biospecimens and clinical data. This approach democratizes research, allowing the entire community to identify the most clinically relevant and pressing questions; any idea can be translated into a study rather than limiting research to the ideas proposed by researchers in grant applications. Preliminary results from the CDCN and other organizations that have followed its Collaborative Network Approach suggest that this model is generalizable across rare diseases.

Purpose The purpose of this systematic review was to determine evidence of a cognate effect for young multilingual children (ages 3;0–8;11 [years;months], preschool to second grade) in terms of task-level and child-level factors that may influence cognate performance. Cognates are pairs of vocabulary words that share meaning with similar phonology and/or orthography in more than one language, such as rose – rosa (English–Spanish) or carrot – carotte (English–French). Despite the cognate advantage noted with older bilingual children and bilingual adults, there has been no systematic examination of the cognate research in young multilingual children. Method We conducted searches of multiple electronic databases and hand-searched article bibliographies for studies that examined young multilingual children's performance with cognates based on study inclusion criteria aligned to the research questions. Results The review yielded 16 articles. The majority of the studies (12/16, 75%) demonstrated a positive cognate effect for young multilingual children (measured in higher accuracy, faster reaction times, and doublet translation equivalents on cognates as compared to noncognates). However, not all bilingual children demonstrated a cognate effect. Both task-level factors (cognate definition, type of cognate task, word characteristics) and child-level factors (level of bilingualism, age) appear to influence young bilingual children's performance on cognates. Conclusions Contrary to early 1990s research, current researchers suggest that even young multilingual children may demonstrate sensitivity to cognate vocabulary words. Given the limits in study quality, more high-quality research is needed, particularly to address test validity in cognate assessments, to develop appropriate cognate definitions for children, and to refine word-level features. Only one study included a brief instruction prior to assessment, warranting cognate treatment studies as an area of future need. Supplemental Material https://doi.org/10.23641/asha.12753179
