Questionnaire | EPFL Graph Search

A questionnaire is a research instrument that consists of a set of questions (or other types of prompts) for the purpose of gathering information from respondents through survey or statistical study. A research questionnaire is typically a mix of close-ended questions and open-ended questions. Open-ended, long-term questions offer the respondent the ability to elaborate on their thoughts. The Research questionnaire was developed by the Statistical Society of London in 1838. Although questionnaires are often designed for statistical analysis of the responses, this is not always the case. Questionnaires have advantages over some other types of survey tools in that they are cheap, do not require as much effort from the questioner as verbal or telephone surveys, and often have standardized answers that make it simple to compile data. However, such standardized answers may frustrate users as the possible answers may not accurately represent their desired responses. Questionnaires are als

MoDN-Flip: Optimizing Modular Clinical Decision Support Networks with Decision Flippability Score

Kuan Tung

BACKGROUND. Clinical Decision Support Systems (CDSS) are point-of-care questionnaires that guide consultations to evidence-based predictions with the aim of standardizing care and optimizing resource allocation. The data collected in these tools contain potentially useful insights to further train its predictive algorithms, however, the questionnaire structure biases data with systematic missingness, making it unusable in traditional models. Further, privacy and interoperability issues make it challenging to synergize with data collected in related CDSS tools. The Modular Decision Support Network (MoDN) was previously proposed by our group to address these issues. It can predict diagnoses at each step in a consultation using sequentially encoded questions. However, it lacks the ability to provide information on unencoded questions, such as predicting their importance, which could potentially optimize questionnaire structure. AIM. In this work, we aim to optimize MoDN by deriving a flippability score (FS) which computes the importance of a question in the form of how likely its answer would flip (change) the predicted diagnoses. METHODS & FINDINGS. The FS is computed with the help of MoDN’s feature decoders that predict unknown feature values in the data. The optimal questionnaire order is then derived by feeding MoDN the question with the highest FS. This approach—-MoDN-flip—- is validated on two independent real world CDSS-derived data sets of pediatric outpatients. We show that FS-optimized question order can achieve the baseline predictive performance 14.71% faster (or with 3.53 fewer questions) compared to MoDN with the original question order. FS-optimized questionnaires are also able to improve the cumulative F1 score by 5.24%. Furthermore, we test the utility of FS-optimization when porting MoDN to an imperfectly interoperable data set (i.e. with slightly different questionnaire structures and partially-overlapping feature sets). The results show that the score is valid in a new dataset and can provide better predictive performance at an earlier stages, albeit a slight cost to final performance. CONCLUSION. With the aim of providing data-driven questionnaire optimization for CDSS tools, we propose the flippability score, which indicates the importance of each potential question in a consultation. The experimental results show that FS can express predictive importance of questions and has the potential to significantly optimize questionnaire structure. It is now necessary to evaluate this ordering against human consultation logic.

Visualising and revitalising traditional Chinese martial arts Visitors' engagement and learning experience at the 300 years of Hakka Kungfu

Sarah Irene Brutton Kenderdine, Jeffrey Shaw

Purpose The purpose of this paper is to examine how the emergent 3D interactive media technologies are used as a viable tool for enhancing visitors' overall experiences at an exhibition entitled, 300 Years of Hakka Kungfu - Digital Vision of Its Legacy and Future (Hakka Kungfu Exhibition) - presented and co-organized by the Intangible Cultural Heritage Office of Hong Kong, International Guoshu Association and the School of Creative Media, City University of Hong Kong. Design/methodology/approach A questionnaire survey in both online and paper-based formats was used for identifying visitors' experiences in the interactions with the multimedia technologies. For this research study, a questionnaire, consisting of 26 items, was set out to measure the visitors' experiences at the Exhibition. Since the Exhibition was about presenting a centuries-old Chinese cultural heritage, Hakka Kungfu via the use multimedia technologies, in the context of establishing a dialogue between the past and present, the researchers included questionnaire items that were devoted to enquire about the level of understanding, knowledge and enjoyment, and visitors' new knowledge about Hong Kong history and culture was successfully disseminated to the respondents at the end of the questionnaire. Findings A total of 209 completed questionnaires were collected at this Hakka Kungfu Exhibition. The findings reveal that the exhibits did attract people at all ages. This Exhibition gave the visitors a sense of interest and wonder in the object and information presented in the Exhibition. Findings of this study also reveal that this Exhibition has successfully attracted a large number of female visitors, as well as visitors who have never taken any martial arts training. In addition, visitors' Exhibition experience was found to be memorable, as well as enjoyable. Furthermore, visitors' experience within the Exhibition suggested that it was entertaining, as well as educational. By creating a long-lasting impact on the minds of these Exhibition visitors about the connections between and relevance of traditional Chinese Kungfu, their collective cultural identity, as well as the contemporary society we live in. The Exhibition exemplified the successful integration of the presentation of Kungfu as a form of cultural heritage with engagement-creating technology, in which technology is unobtrusive but effective. Originality/value Although it is already a global trend for the museums to integrate multimedia technologies into their exhibitions, research on the situation and feedback of multimedia technology used in the museum exhibitions in Hong Kong is scarce as well as scattered. Findings of this study could help identify various factors involved in audience participation, thereby exploring the possibility of building a contact point/space for traditional Chinese Kungfu as an intangible cultural heritage, via the integration of the latest media technologies. In particular, the development of multimedia technologies has become increasingly important to museums, and museum professionals have been exploring how digital and communication technologies can be developed to offer visitors a more interactive, personalized museum experience. In general, despite the growing interest in deploying digital technology as interpretation devices in museums and galleries, there are relatively few studies that examine how visitors, both alone and with others, use new technologies when exploring the museum contents.

Impact de la communication voco-visuelle dans le management sur la motivation des collaborateurs

Our research work wishes to highlight the importance of the relationship between the vocal and physical behaviour of the manager and team motivation. In order to investigate this important relationship, a survey by means of a questionnaire and two field studies were undertaken. The survey has notably showed that in communication situations the working population questioned is above all sensitive to physical behaviour. The people questioned often put vocal communication in second place. It should be noted that their principal factor of motivation within the professional environment is recognition and respect for the individual. According to them, for physical behaviour, it is mainly through the eyes, followed by facial expressions and then the manager's posture that recognition and respect for the individual are expressed. With regard to vocal behaviour, these elements can be expressed through the intonation, tone and loudness of the voice. The field studies and the decision to prioritize the analysis of physical behaviour allowed us to confirm whether this body language, a sign of recognition and respect of the individual and therefore source of motivation, was a reality and resulted in a successful contact. In the working place, the way the manager looks at his team, notably, can be lacking or even absent and consequently this absence can be perceived as a closure. Therefore, if we follow our logic, this could have an influence on staff motivation. We therefore decided to complete our field studies by having the teams pass a connotation test to find out their real feelings towards their manager's behaviour. It appears that the manager's recognition for them takes second place to other equally necessary managerial qualities such as strength, endurance and a proactive personality which are widely accepted. The conclusions of the questionnaire survey have therefore been confirmed by the qualitative study. By proceeding stage by stage, our research has therefore managed to confirm the real relationship between the principal factor of motivation for staff "recognition and respect of the individual" and the physical behaviour "look, facial expression and posture" which expresses this recognition. And by really taking into consideration the relationship of vocal and visual behaviour to motivation, every manager can encourage a better quality of understanding within his team. This active listening will allow him to build a complementary and successful team by placing the right person in the right place! Henceforth, every individual's satisfaction at work becomes progressively a collective effort and a real social culture within the working place begins to grow…
