Audience Response System Technology for Pediatric Postgraduate Training

We report our experience of using Audience Response System among 21 pediatric postgraduate residents in pediatrics as a mode of teaching. Apart from significant improvement in test scores, three-fourth of the participants felt it was an interesting way to learn actively and was better than the traditional audio-visual presentation during lectures.

ESTETIKA MASKULIN DAN EKSKLUSI PEREMPUAN DALAM FILM EKO-KRITIK SEORANG KAMBING (2016)

The eco-critical film, Seorang Kambing (Tunggung Banjaransari, 2016), is part of eco-cinema, which mainly talks about problems of water crisis throughout its narrative. Eco-cinema has not only audio-visual presentations regarding environmental issues, but also functionalizes aesthetic choices, which could encourage viewers to have mindful and critical awareness of ecological problems. This article is aimed to examine how the film narrative of Seorang Kambing reproduces gender problems around the issue of water crisis. This article uses Stella Bruzzi’s (2013) concept of masculine aethetics in the cinema and the approach of eco-feminism, which critically reveals the connections between the oppressions of the nature and those toward women. By applying narrative analysis, which is presented by Helen Fulton (2005), this article reveals that masculine aethetics are functionalized predominantly in the film to narrate the problems of water crisis. Paradoxically, Seorang Kambing, as an intended eco-critical film, seems to simply overlook the significant roles of women around the issue of water crisis. In addition, the film reproduces the exclusion of women from the discourse of water crisis.

Ethics and standards of online news in Bangladesh

The mixed media, comprising of mainstream newspapers and electronic media along with ‘new media’ of on-line reporters, reporting is rapidly developing. Enormous technological and economic changes have propelled the substantial progress in journalism. Such developments also require ethical framework for operation like any other media. The paper looks into Bangladeshi online news media's ethical and moral standards. Over the past five-six years, the total use of online news media has risen in Bangladesh. The modern form of journalism provides readers the platform of pace, interactive elements, audiovisual presentation and so much more. The study found that a very limited number of online news media operating in Bangladesh follow ethical standards. In many ways, this news medium violated the ethical standards. This study shows the ethics and standards in the presentation of news, coverage style and views and the information they give is imprecise in accurate and quite often stereotyped.

A Novel assessment tool monitoring the level of patient anxiety during third molar surgery procedure

The authors hypothesized that an audio-visual presentation providing information regarding the removal of an impacted mandibular third molar would reduce patient anxiety. Aim& objectivesA clinical trial was performed to assess the level of patient anxiety during third molar surgery by using a new induction program and comparing the results amongst two groups that were the verbally informed and the audio-visual informed groups. Materials and methodsthe clinical trial included the patients who required surgical removal of an impacted third molar and fulfilled the predetermined criteria. The patients were divided into two groups - group 1 (no. = 20) the audio visual informed group and group 2(no. = 20) the verbally informed group. For both the groups the HR was recorded beat by beat using HR sensor (polar H1 UK) connected to an ActiGraph WGT3X- 3T USA. Also the modified dental analogue scale(MDAS) was used to subjectively record the anxiety during the surgery. ResultsThe HR reading were statistically significant for the following surgical stages; drilling, suturing and upon leaving the clinic. The audio-visual informed group had lower self-reported anxiety scores than did the verbally informed group. ConclusionThese results suggested that providing an audio-visual presentation about the surgical procedures in our routine clinical practice could aid in alleviating anxiety which would thereby reduce surgical complications.

Three-year-olds infer polite stance from intonation and facial cues

AbstractDespite the evidence that infants are sensitive to facial cues and prosody for the detection of emotion, we have contradictory evidence regarding the use of these cues by older preschool and school children when inferring both emotional and politeness stance. This study assessed preschool aged children’s sensitivity to intonational and facial cues signalling a speaker’s polite stance in requestive speech acts with controlled lexical and contextual materials. Thirty-six 3-year-old American English-speaking children performed a forced-choice decision task which investigated whether children at this age use pitch and/or facial cues to infer a speaker’s affective stance in either audio-only, visual-only or audio-visual presentation modalities, when lexical cues are controlled for. Results showed that (a) children at three years can infer a speaker’s polite stance equally well in all three conditions (audio-only, visual-only and audio-visual) and thereby (b) unlike previous research, in the present task both intonation and facial cues are equally strong cues in children’s understanding of a speaker’s polite stance in requestive speech acts. The authors discuss especially the implications of this early use of intonation to detect politeness, relating it to other previous research on children’s ability to infer meaning from pitch.

Co-creation of a post-traumatic brain injury sexuality information toolkit: a patient-oriented project

Aim Different studies and two clinical practice guidelines emphasize the necessity to provide patients undergoing rehabilitation with information about commonly occurring changes in sexuality following traumatic brain injury (TBI). The purpose of this study was to co-create information resources for individuals with moderate to severe TBI and their partners to consult during rehabilitation. Methods An iterative user-centered design was used, combining focus group and individual interviews. A convenience sample of individuals with TBI and life partners was constituted. Results The needs and expectations of these participants in terms of form and content of an information toolkit on post-TBI sexuality were explored. The subjects that matched the interests and needs of participants were numerous and supported by the literature. Contrasting with existing written resources, the participants' views oriented the creation process toward the development of a toolkit including five audiovisual presentations, a double-sided information sheet, and a checklist. Conclusions A similar approach of co-creation could be used to develop other information packs aimed at patients with other disabilities. The created material is expected to be a usable and useful tool for individuals with TBI, which can support clinicians in addressing the subject of sexuality. Implications for rehabilitation The central role held by individuals with moderate to severe traumatic brain injury, in identifying the sexuality related topics to be addressed and the form of resources to be created, led to a better understanding of their needs. This patient-centered research brought solutions to difficulties related to the understanding of health information, prevalent among patients. This patient-oriented project highlights the necessity for adequacy between the health information provided by rehabilitation professionals and the capacity of their patients’ to seek for, process, and understand its content.

330.3: Utilizing metro stations for organ donation awareness – a first-ever initiative in India.

Background: Public spaces are great places for spreading the message about organ donation. The space is free and has many visitors of all age groups on a daily basis. MOHAN Foundation used Chennai Metro stations for different activities to drive home the organ donation message. Methods: MOHAN Foundation is a non-profit, non-governmental organization in India, engaged in the area of deceased organ donation for the past 22 years. It is the largest organ donation organization in India. Through its seven offices, spread across India, MOHAN has actively pursued organ donation awareness programs among the cross section of our population. While there are over 20 million donor cards distributed on the ground, 53,540 people have pledged for organ donation since March 2010 through our website, www.mohanfoundation.org. To mark the 50th anniversary of Heart Transplantation, MOHAN Foundation organized a concert titled “Metro Retro” on December 3rd, 2017 – the first-ever awareness initiative for organ donation at a Metro station. Most popular musicians, “Ranjani & Gayatri Sisters” performed at the Vadapalani Metro Station, wherein 800 music aficionados attended the event. Results: At the Metro Retro event, 80 participants pledged for organ donation. Encouraged with the response from this event, we organized a “Color Art” (Rangoli) Festival on 6th January 2018, which saw 80 enthusiastic participants. India observes the week of 2nd October to 8th October as “Joy of Giving Week” to mark the birthday of Father of Nation, Mahatma Gandhi. During this time, MOHAN put up booths to spread awareness about organ donation. During this time, 130 people pledged for organ donation. Again on 24th November, 2018, a “Visual Art Festival” was organized wherein students were invited to participate in a visual arts competition on organ donation. 200 students participated and their work was exhibited at Vadapalani Metro Station. 150 people pledged for organ donation during the festival. With increased awareness, the Chennai Metro Rail Limited invited MOHAN Foundation to its office for an audio visual presentation. 25 staff members participated out of which 5 pledged for organ donation. Conclusions: Public places like Metro Stations are worth exploring for organ donation awareness. Official permission from the Metro office has helped us greatly. They are always open to such philanthropic activities.

Temporal exaggeration facilitates second language phonetic training: The case of syllable-final nasal contrast

This study tested the generalizability and efficacy of a modified high-variability phonetic training (HVPT) method with temporal exaggeration. The target sounds were the syllable-final /n/-/ŋ/ contrast in English, which was found to be difficult for adult Mandarin Chinese speakers. Our training software program featured systematically controlled temporal exaggeration, multi-talker variability, audio-visual presentation, and adaptive listening. The participants were 24 Chinese college students, and they were randomly assigned to two groups. Pre- and post-tests were administered one week before and after training in the experimental group, including behavioral identification and discrimination of /n/-/ŋ/. The control group who did not receive training took the same tests. In addition, mismatch negativity (MMN) responses were also obtained from the training group to assess the training effects in within- and across- category discrimination without requiring focused attention. Compared with the control group, the training group showed enhanced categorical perception of the nasal contrast with corresponding changes in the MMN responses to within- and across- category differences. The data provide further evidence for incorporating temporal exaggeration in high variability phonetic training to promote brain plasticity at the perceptual and pre-attentive neural levels.

CREATING BRANDED COMPUTER GAME ELEMENTS AS A FORM OF CUSTOMER ENGAGEMENT

Nowadays companies want to engage customers in all possible ways to better meeting their needs. New media gave managers opportunities to interact with people and establish cooperation. Present paper is aimed to give an outlook on creating branded computer game elements as a customer engagement behavior. The author carried out 20 in-depth interviews with users of three computer games: The Sims, Second Life and Euro Truck Simulator 2. The results show that players create branded game modifications with interference only into audiovisual presentation and interference in the game code. Inside the games, it can be find also a wide range of fictitious brands that replace the real one, among others for legal reason. The authors tried to answer the question why people engage in creating branded game elements. Based on some players statement during the interviews it can be assumed that players create branded elements for few reasons. They want to diversify the game, create some items as an entertainment activities, want to raise the realism of the game, need to belong to some community and also create add-ons to earn money.

Adding Acoustical to Visual Movement Patterns to Retest Whether Imitation Is Goal- or Pattern-Directed.

This study compared two different motor skill modeling presentations (with and without goal display) in visual and audio-visual conditions for learning a complex skill (basketball jump shot) to evaluate the importance of (a) audio information and (b) goal observation in motor performance kinematics. Specifically, we sought to understand whether the simultaneous presentation of auditory and visual patterns could usefully direct the learner's attention from goal to pattern stimuli. I selected 40 students (Mage = 20.47 years) who had no prior experience with the basketball jump shot or free throw and randomly assigned them into four groups: Pattern/Visual, Pattern/Audio-Visual, Pattern-Goal/Visual, and Pattern-Goal/Audio-Visual. Participants in the pattern-only groups watched only the skilled motor pattern, while those in the pattern-goal groups watched both the pattern and its outcome. Participants in the visual-only groups simply watched the visual pattern, while those in audio-visual groups saw and heard the pattern; we sonified the angular velocity of the skilled performer's elbow joint. Participants then performed in two conditions with and without balls. On all dependent variables, the participants' performance following the audio-visual presentations was better than when following the visual-only presentations. In addition, the participants' performance in pattern-only groups was better than in pattern-goal groups, but this improved pattern-only performance was far less extensive in the audio-visual than in the visual-only group. In sum, complex motor skill imitation was enhanced by an audio pattern of elbow angular velocity in support of generalist theories of imitation learning.

Unitization modulates recognition of within-domain and cross-domain associations: Evidence from event-related potentials.

Although it is often assumed that memory of episodic associations requires recollection, it has been suggested that, when stimuli are experienced as a unit, earlier memory processes might contribute to their subsequent associative recognition. We investigated the effects of associative relations and perceptual domain during episodic encoding on the ability to utilize early memory processes to retrieve associative information. During the study phase, participants encoded compound and noncompound words pairs, presented either to the same sensory modality (visual presentation) or to different sensory modalities (audiovisual presentation). At the test phase, they discriminated between old, rearranged, and new pairs while ERPs were recorded. In an early ERP component, differences related to associative memory emerged only for compounds, regardless of their encoding modality. These findings indicate that episodic retrieval of compound words can be supported by early‐onset recognition processes regardless of whether both words were presented to the same or different sensory modalities, and suggests that unitization can operate at an abstract level, across a broad range of materials.

Information retention of orthodontic patients and parents: A randomized controlled trial.

A randomized controlled trial was undertaken to compare the efficacy of 3 methods of delivering information on short- and long-term recall of information in orthodontic patients and parents. Participants who received an audiovisual presentation on orthodontic treatment were randomly allocated to 1 of 3 written information groups (leaflets, generic mind map, or participant's customized mind map). A questionnaire was used to assess short- and long-term retention of information (maximum score 30). Eighty-eight patients (94.6%) and 77 parents (86.5%) completed the study. The average knowledge scores at baseline for the patient groups were 17.71 95 CI 16.28-19.14), 16.58 (14.67-18.49), and 17.37 (15.92-18.81), respectively. The parents' knowledge scores for the 3 groups were 19.06 (17.51-20.62), 19.39 (17.44-21.35), and 18.76 (17.19-20.33), respectively. The short- and long-term knowledge scores improved over baseline in all 3 groups (P<0.0001). The parents achieved higher scores than the patients (P=0.002) and their rate of forgetting information was less. The knowledge scores of the mind map groups were higher than that of the leaflet group for all cohorts (P=0.025). No statistical difference was found between the type of mind map. The correlation between patient and parent knowledge scores was significant (P<0.0001) at all 3 time points. Provision of an audiovisual presentation supplemented with 1 of 3 written information methods is an effective way of delivering information. There was a significant improvement in the retention of information with the use of mind maps compared with leaflets. The generic mind map is equally as effective, more consistent in information delivered, and less labor intensive than the individual customized mind map and therefore would be our recommendation. Participation of parents is important because they comprehend and retain information better. In this study, 100% of parents shared information with their children, perhaps improving the patients' recall.

The audio-visual integration effect on music emotion: Behavioral and physiological evidence.

Previous research has indicated that, compared to audio-only presentation, audio-visual congruent presentation can lead to a more intense emotional response. In the present study, we investigated the audio-visual integration effect on emotions elicited by positive or negative music and the role of visual information presentation durations. The participants were presented with audio-only condition, audio-visual congruent condition, and audio-visual incongruent condition and then required to judge the intensity of emotional experience elicited by the music. Their emotional responses to the music were measured using self-ratings and physiological aspects, including heart rate, skin temperature, EMG root mean square and prefrontal EEG. Relative to the audio-only presentation, the audio-visual congruent presentation led to a more intense emotional response. More importantly, the audio-visual integration occurred both in the positive music and in the negative music. Furthermore, the audio-visual integration effect was larger for positive music than for negative music; meanwhile the audio-visual integration effect was strongest with the visual information presented within 80s for negative music, which indicated that this integration effect was more likely to occur in the negative music. These results suggest that when the music was positive, the effect of audio-visual integration was greater. When the music was negative, the modulation effect of the presentation durations of visual information on the music-induced emotion was more significant.

An EEG-Based Identity Authentication System with Audiovisual Paradigm in IoT.

With the continuous increment of security risks and the limitations of traditional modes, it is necessary to design a universal and trustworthy identity authentication system for intelligent Internet of Things (IoT) applications such as an intelligent entrance guard. The characteristics of EEG (electroencephalography) have gained the confidence of researchers due to its uniqueness, stability, and universality. However, the limited usability of the experimental paradigm and the unsatisfactory classification accuracy have so far prevented the identity authentication system based on EEG to become commonplace in IoT scenarios. To address these problems, an audiovisual presentation paradigm is proposed to record the EEG signals of subjects. In the pre-processing stage, the reference electrode, ensemble averaging, and independent component analysis methods are used to remove artifacts. In the feature extraction stage, adaptive feature selection and bagging ensemble learning algorithms establish the optimal classification model. The experimental result shows that our proposal achieves the best classification accuracy when compared with other paradigms and typical EEG-based authentication methods, and the test evaluation on a login scenario is designed to further demonstrate that the proposed system is feasible, effective, and reliable.

Duma i uprzedzenie jak historia romantyczna. O adaptacji powieści Jane Austen w reżyserii Joe Wrighta

Pilawska Roksana, Duma i uprzedzenie jak historia romantyczna. O adaptacji powieści Jane Austen w reżyserii Joe Wrighta [Dirty (un)Romantic story. An Analysis of Aesthetic Aspects in the Film Adaptation of Pride and Prejudice Directed by Joe Wright]. „Przestrzenie Teorii” 32. Poznań 2019, Adam Mickiewicz University Press, pp. 417–431. ISSN 1644-6763. DOI 10.14746/pt.2019.32.23.&#x0D; The aim of my study is to attempt a comparative analysis of the two most famous film adaptations of the bestselling novel by Jane Austen, Pride and Prejudice. As research material, I chose the mini-series produced by the BBC in 1995, which was part of the then popular trend of heritage films (heritage cinema) and the feature film from 2005, directed by Joe Wright, which, in the opinion of film experts, was a completely new form of audiovisual presentation of Austen’s work. In the article, I focus only on interpreting the aesthetic aspects of both productions, which would indicate similarities and differences, thus showing numerous shifts of emphasis in the aesthetic layer of the newer version.

Towards an Audio-Locative Mobile Application for Immersive Storytelling

We live in an age in which digital media is omnipresent and augmented reality is beginning to find its way into our everyday lives, GPS allows us to determine our position with meter precision and the sensor capabilities of smartphones are increasing. All these technologies in combination enable us to explore one of the oldest human art forms in a new way: storytelling. The presented work aims at developing approaches that combine different elements of audio media playback, geolocation and other sensor capabilities of smartphones to allow the creation of immersive geolocated narratives within a mobile application. Thus, the narrative can be precisely adjusted to the specific spatial and temporal context of the user. One of the main goals of such a geolocated narrative would be to influence the cognitive processing of the users. As the visual perception of the location stays the same while using the app, it is only the auditory cognition that causes a subtle enhancement and thus alteration of the reality which could result in a very strong sense of immersion. There are many location-based audio applications on the market. Most of them are intended for tourism in the form of an audio tour guide. Some of those applications have been analyzed before developing our own ideas on how to intertwine sound, space and time into an immersive mobile application for storytelling with semi-linear narrative structures including a map. Possible features could be influenceability of the narrative by, e.g., speed or approach direction of the user, sound movement over time on predetermined routes, etc. The first prototype implemented some audiovisual presentations among others.

Circular economy and behaviour change: Using persuasive communication to encourage pro-circular behaviours towards the purchase of remanufactured refrigeration equipment

Refrigerated Display Cabinets (RDCs) are used in the retail sector to display chilled and frozen food, and beverages. The manufacture of RDCs is typified by the extensive use of materials and energy, meaning that the development of a Circular Economy in this sector is particularly important.A number of behavioural barriers are preventing the development of the Circular Economy but an appropriate behaviour change intervention could help to overcome them. This paper investigates how effective the use of Persuasive Communication could be in influencing the Behavioural Attitudes, Product Perceptions and Behavioural Intentions towards the purchase of remanufactured RDCs. Participants in this study are engineers and academic experts of retail refrigeration equipment.The study was carried out in three consecutive stages. In the first stage participants completed a questionnaire, which assessed their Behavioural Attitudes, Product Perceptions and Behavioural Intentions. In the second stage participants were exposed to the intervention, which was the Persuasive Communication in the form of an audio-visual presentation. In the third stage participants completed a second questionnaire which assessed the impact of the intervention. The results show that the Persuasive Communication had a positive impact on the participants' Behavioural Attitudes, Product Perceptions and Behavioural Intentions towards the purchase of remanufactured RDCs. This paper demonstrates how effective this type of intervention could be, if developed further to create a target market and generate demand for remanufactured RDCs.

Utilization of a BMT Nursing Symposium to Standardize Education of BMT Staff

Topic Significance & Study Purpose/Background/Rationale To support our mission and provide our patients competent and professional care, we realized that we have to provide our nurses and support staff with comprehensive education. With increasing complexity of care, rapid development of immunotherapies and cellular therapies, and a significantly growing transplant program, it is imperative for not only BMT staff, but also staff from other BMT ancillary services, to have the knowledge and skills to successfully care for this patient population. Methods, Intervention, & Analysis A comprehensive BMT Nursing Symposium with interactive audio-visual presentation and question & answer session was developed by the BMT program. The day-long symposium covered a wide variety of topics including overviews of autologous and allogeneic transplants, as well as post-transplant complications including graft versus host disease, febrile neutropenia, CMV reactivation, and veno-occlusive disease. Additional topics regarding support services included nutrition, social work, stem cell collection and processing, and histocompatibility testing. All topics are presented by experts in the field including BMT physicians, pharmacists, and nurse practitioners. The symposium also included a portion on nursing care of the BMT patient. Two identical sessions of the symposium were offered in order to accommodate all staff's schedules while still allowing coverage off the inpatient and outpatient areas. All BMT nursing staff including inpatient, outpatient, and infusion areas are required to attend. The symposium is also offered to nursing staff in the Intensive Care Unit's (ICU) and Emergency Department's (ED) as these departments treat BMT patients. A seven hour Continuing Education Unit (CEU) credit was offered to the participants. Findings & Interpretation The BMT team recently held the third annual BMT Nursing Symposium. Attendance at the symposium has increased each year with the most recent symposium reaching 80 attendees, a 25% increase from year one. After the symposium, surveys are distributed to determine how effective the presentations were. Overall, the symposium receives positive reviews. Staff also has the opportunity to suggest new topics for future years. Discussion & Implications Nurses have a great impact on the quality of care bone marrow transplant patients receive. By standardizing education for our staff, we hope to give our new hires a solid foundation, while at the same time reaffirming the foundation in our seasoned employees. Patients also interact with our support staff, so it is important for us to educate our entire multidisciplinary team so the patient can have uniform and consistent care throughout the whole treatment process. In the next few years, we hope to cover additional topics including cellular therapy. Also, if needed, we would like to explore the idea of having two tracks for the symposium – one for new employees and one for more experienced employees. Institutions should consider implementing a similar symposium to standardize staff education on the complexities of treating the BMT patient.

Does the provision of a DVD-based audio-visual presentation improve recruitment in a clinical trial? A randomised trial of DVD trial invitations

BackgroundRecruitment to clinical trials can be challenging. Methods that improve the efficiency of trial recruitment are needed to increase successful study completions. The aim of this study was to ascertain whether sending an audio-visual presentation on a digital versatile disc (DVD), along with usual study invitation materials, would improve recruitment to the Febuxostat versus Allopurinol Streamlined Trial (FAST), a clinical trial in patients with established gout.MethodsPotential participants for the FAST study who were identified by searches of GP records in Scottish primary care practices between August 2013 and July 2014 were included in this study. Individuals were randomly allocated to receive either a standard invitation (letter and information leaflet) or a standard invitation and a DVD containing an audio-visual presentation explaining the background and operation of FAST. Data on invitation response rates, screening attendances and randomisations were collected by research nurses.ResultsOne thousand fifty potential participants were invited to take part in FAST during this period. 509 individuals were randomised to receive the DVD presentation and the standard invitation and 541 received a standard invitation only.DVD recipients were less likely to respond to the initial invitation (adjusted OR 0.76, CI 0.58–0.99) and marginally less likely to return a positive response (OR 0.75, CI 0.59–0.96). There was no statistically significant difference between the groups in attendance for screening or randomisation. The DVD did not influence the age, gender, or socioeconomic deprivation scores of those responding positively to a letter of invitation.ConclusionsThe inclusion of a DVD presentation with FAST study invitations did not make any practical difference to the rate of positive response to invitation. Further innovation and evaluation will be required to improve recruitment to clinical trials.Trial registrationEU Clinical Trials Register. EudraCT Number: 2011–001883-23.ISRCTN registry.
