How to use Data to Increase Bike Use by Travellers

Abstract The Government of the Netherlands wants to be energy neutral by 2050 (Rijksoverheid, sd). A transition towards non-fossil energy sources also affects transport, which is one of the industries significantly contributing to CO2 emission (Centraal Bureau Statistiek, 2019). Road authorities at municipalities and provinces want a shift from fossil fuel-consuming to zero-emission transport choices by their inhabitants. For this the Province of Utrecht has data available. However, they struggle how to deploy data to positively influence inhabitants' mobility behavior. A problem analysis scoped the research and a survey revealed the gap between the province's current data-item approach that is infrastructure oriented and the required approach that adopts traveler’s personas to successfully stimulate cycling. For this more precisely defined captured data is needed and the focus should shift from already motivated cyclists to non-cyclers.

Cold case Solved andamp; Unsolved: Use of digital tools and data science techniques

On average 125 murders take place in the Netherlands on an annual basis. However, not all such incidents can be solved. Currently there are more than 1700 unsolved homicide cases on the shelf at the National Police that classify as a andapos;cold caseandapos;. Investigation into these types of capital offenses takes a lot of time, money, and capacity. Applications of the current working method and available techniques are very labor-intensive and time-consuming. In addition, the pressure on the executive Police officers is high-from the Police organization, the Public Prosecution Service, the media, the next of kin, as well as society in general. From an investigative point of view, it is relevant to provide direction in the criminal investigation and formulate and evaluate various case scenarios, while reducing a risk of andapos;tunnel visionandapos;. From a scientific point of view, more research into homicide cases in the Netherlands is of eminent importance. Remarkably little has been written in scientific literature about this type of crime. The project andapos;Cold Case: Solved andamp; Unsolvedandapos; focused on the use of open, publicly available information sources to collect the data and gain more insight into homicide cases in The Netherlands. Applicability of various modern techniques, such as web-scraping, API software and Artificial Intelligence (AI) was explored to facilitate and automate data collection and processing tasks. A first concept of a andapos;smartandapos; database was proposed, combining a web-based database platform with AI modules to filter and (pre-)process the data. With further development and training of AI modules, such a database might eventually support data-driven generation and/or prioritization of investigative scenarios. The data collected in the process was used in three scientific studies aimed at uncovering the relationships and patterns in the homicide data for The Netherlands.

Fostering effective teaching behavior through the use of data-feedback

In this study data-feedback in a cyclic model of data-driven teaching was used to enhance the teaching behavior of students registered in a master course for teachers. Differences between pre- and post-test measures in a simple one-group pre-test post-tests design proved to be significant with effect sizes ranging from d = 0.29 to d = 0.76. Improving teaching behavior in a time span of only six weeks on average is remarkable since earlier studies indicated that it takes over 15 years to master complex teaching skills with a ‘natural development’ of teaching skills of about 25% of a standard deviation.

Action research as a qualitative research approach for understanding technology professional development in higher education

Over the last two decades, institutions for higher education such as universities and colleges have rapidly expanded and as a result have experienced profound changes in processes of research and organization. However, the rapid expansion and change has fuelled concerns about issues such as educators' technology professional development. Despite the educational value of emerging technologies in schools, the introduction has not yet enjoyed much success. Effective use of information and communication technologies requires a substantial change in pedagogical practice. Traditional training and learning approaches cannot cope with the rising demand on educators to make use of innovative technologies in their teaching. As a result, educational institutions as well as the public are more and more aware of the need for adequate technology professional development. The focus of this paper is to look at action research as a qualitative research methodology for studying technology professional development in HE in order to improve teaching and learning with ICTs at the tertiary level. The data discussed in this paper have been drawn from a cross institutional setting at Fontys University of Applied Sciences, The Netherlands. The data were collected and analysed according to a qualitative approach.

Multimodal speech data acquisition with the use of EMA, fast-speed video cameras and a dedicated microphone array

Electromagnetic Articulography (EMA) is a technology created over two decades ago. EMA enables to acquire spatiotemporal data from sensors placed on the tongue in order to obtain information about the positioning of the tongue, its shape and dynamics during vocalizations of various sounds of human speech. The articulograph is often supported by an audio recorder and a vision system. In this paper, a novel system integrating EMA, audio and visual data recording is presented. The articulatory data was obtained with a Carsten's AG500 articulograph. The vision system was constructed from 3 high-speed cameras (Gazelle GZL-CL-22C5M-C) manufactured by Point Grey. The cameras registered movements of markers attached to the face of the speakers. The audio recorder consisted of a 16-channel microphone array and an electronic device that registered and processed signals from the microphones. The microphone array made it possible to map sources of sound propagation on the speaker’s face. The simultaneous recording of signals from EMA, the video system and the audio recorder is controlled from a computer with a host program and is supported by a synchronizer. The electromagnetic articulograph registers signals from EMA sensors which return their spatiotemporal positions with the sampling frequency of 200 Hz. The readouts of the spatial positioning of sensors attached to the tongue provide information about its shape and movements in time. There are three cameras registering the movements of external articulators and organs (e.g. lips, jaw and cheeks) from the front and side views. The cameras register movies with the frame rate of 200 FPS. The circular microphone array with 16 microphones records 16-channel audio with 96 kHz sampling rate and 16 bit resolution. During the recording sessions, the participants read aloud words that are displayed on the screen. An application on the host computer sends commands to AG500 which in turn generates synchronization signals in the TTL standard to external devices. These signals are used for activating the audio recorder and the synchronizer in the video system. Articulographic and simple acoustic analysis is performed with created in MATLAB software called phonEMAtool. This software is very useful and ergonomic for fast feature extraction of tongue movements during speech. The application allows to display simultaneously: speech waveform, EMA sensors position and orientation, phonetic segmentation. Before an analysis, the data from AG500 are pre-processed twice with a Savitzky-Golay filter so as to remove undesirable noise. In the paper an exemplary analysis performed by the phonEMAtool of particular articulatory gestures in the articulation of [m] in the Polish word Tamara is presented. Another analysis is beamforming of audio signals in order to obtain three-dimensional acoustic field distribution images. In the paper an example of this technique applied to the analysis of the nasal consonant in the word Tamara [tamara] has been shown. Analysis indicated that the highest intensity of the acoustic field during the pronunciation of the consonant [m] occurs in the nose region and for vowel [a], the highest intensity is observed in the mouth. Due to movement registration of facial markers the reconstruction of positions of external articulators can be obtained. With additional face triangulation using Delaunay algorithm some differences between positions of external articulators can be easily tracked. The measurement system described in this paper is effective and allows for an examination of the vocal tract in 3 ways: tongue movements, acoustic field intensity distribution and external articulator movements. A particularly useful tool is the dedicated acoustic camera based on multi-channel audio recorder and a microphone array. The results obtained with this equipment are unique and show great research and application potential.
