Schlafenszeiten, Fernseh- und Computergewohnheiten von Grundschulkindern in Deutschland
2007
Background Pediatricians recommend daily sleep of at least ten hours for children aged 9 and 10 years. Sufficient sleep is necessary for maintaining the body's homeostasis, as well as for fixing memories and learning. Lack of sleep in children has been associated with a diminished school performance, reduced attention span, and obesity. Adulthood is influenced by childhood lifestyle habits. Data from 4th graders in 34 schools in Mainz and its surroundings were analysed in order to determine negative health lifestyle factors in German primary school children, such as lack of sleep and increased leisure time spent watching television and computer gaming. Methods Data from a cross-sectional st…
Technology-Enhanced Course in English Theoretical Grammar and Phonetics at the Tertiary Level
2021
The advancement of technologies and the recently forced lockdown by Covid-19 are bringing changes to the organisation of the learning process by accelerating the introduction of e-learning to create a learner-centred technology-based approach to English studies, thus stepping towards digital humanities. These trends initiated the institutional project Mobile and Desktop Software Integration in Bachelor and Master Study Programmes. The present study, using a questionnaire, elicits university students’ attitudes to the mobile applications and speech analysis software-based seminar activities in Moodle e-course in accordance with the blended learning model selected for the studies of theoretic…
A mobile game as a support tool for children with severe difficulties in reading and spelling
2020
We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading …
GraphoLearn India : The Effectiveness of a Computer-Assisted Reading Intervention in Supporting Struggling Readers of English
2018
India, a country with a population of more than 1.3 billion individuals, houses the world’s second largest educational system. Despite this, 100 of millions of individuals in India are still illiterate. As English medium education sweeps the country, many are forced to learn in a language which is foreign to them. Those living in poverty further struggle to learn English as it tends to be a language which they have no prior exposure to and no support at home for. Low-quality schools and poor instructional methods further exacerbate the problem. Without access to quality education, these individuals continue to struggle and are ultimately never given the chance to break the cycle of poverty.…
Geoacoustic Inversion with Drifting Buoys: Enverse 1997–98 Experiments (Marettimo Is.)
2000
Acoustic buoys were developed to allow the rapid determination of range-dependent bottom properties in a shallow water environment from the inversion of propagation measurements. The main features of the buoys are the large dynamic range, digital signal conditioning unit, global positioning system receiver and reliable radio data link. The buoys drift away from a broadband source receiving its pings at known positions. Single hydrophone, matched waveform, inversion techniques are applied to the received signals to invert for geoacoustic parameters. Eight prototypes were tested over the southern continental shelf off the island of Marettimo (Sicily) during the EnVerse 97 sea trials. Calibrat…
Telefonische Beratung für Glücksspielsüchtige – der heiße Draht ins Hilfesystem? Akzeptanz und Nutzung der Mainzer Hotline Verhaltenssucht
2018
Zusammenfassung Ziel Trotz erheblicher psychosozialer Folgen findet nur ein geringer Anteil der pathologischen Glücksspieler den Weg in die Beratung und Behandlung. Telefonische Beratungsangebote (Hotlines) sollen Betroffenen den Weg in das Suchthilfesystem erleichtern. In Deutschland fehlt es an Forschung zur Inanspruchnahme und den Effekten von Hotlines. Es soll die Frage beantwortet werden, ob telefonische Beratungsangebote dazu beitragen, Glücksspielsüchtigen den Weg in das Suchthilfesystem zu bahnen. Methodik Alle Erstanrufe, die auf der Hotline Verhaltenssucht der Universitätsmedizin Mainz zwischen 2013 und 2016 aufgrund eines problematischen Glücksspielverhaltens eingingen, wurden mi…
Some observations on the use of HamNoSys (Hamburg Notation System for Sign Languages) in the context of the phonetic transcription of children’s sign…
2005
This paper discusses the use of the HamNoSys notation (Hamburg Notation System for Sign Languages) for the transcription of children’s signing. The notation system will be briefly described and some former descriptions of the acquisition of sign language phonology presented. The project in which HamNoSys was used is then described briefly followed by a description of the problems encountered while using the notation. Furthermore some proposals as to how to further develop the notation will be made. In conclusion the instrument can be said to be useful and, especially if revised, will be invaluable in further research.
Experience from Indoor Fire Search and Rescue Game Design for Technology Testing
2018
No matter how good the fire evacuation plan for a building is, there is a risk of immovable victims being left behind due to smoke obscuration, inhalation of poisonous gasses, or other reasons. Firefighters usually perform the search and rescue for casualties in responding to fire hazards, besides the firefighting. Among of the challenges in the search and rescue operation is how to locate victims, and to keep monitoring the fire development so that it will not accidentally harm the fire personnel. This paper presents a game designed to test a smartphone app’s feature that supports concurrent tracking of indoor victims and fire spread. 22 volunteers were assigned roles either as rescuers or…
Development and validation in a group of industry workers, of an application for audiometric screening: A solution for social distance during COVID-1…
2020
In the context of the global COVID-19 pandemic, companies and institutions all over the world are trying to find the best ways to reorganize their activity, minimizing the contagion risk among their employees, so as to protect their health and prevent internal SARS-COV-2 outbreaks. The recent development of new communication technologies, such as smartphones and tablets, has paved the way for the development and implementation of different applications. Starting with the above issues, in this study, we wanted to investigate the efficacy of iAudiometry application developed by our research team for the detection of deficits in the auditory system. Furthermore, we analyzed the precision in de…
Synthetic individual binaural audio delivery by pinna image processing
2014
Purpose – The purpose of this paper is to present a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener’s pinna. Design/methodology/approach – The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener’s head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source. Findings – A preliminary localization test shows that the model is able to statically render the elevation of a vi…
