Hothousing: Utilising industry collaborative problem-solving practices for STEAM in schools
2022
Collaborative problem solving (CPS) has been widely used in both industry and in schools over at least the last twenty years. The Industry Hothousing variant of CPS in its adult format is an intensive, time-constrained workshop based process designed to build mutual trust between customers and industry experts in order to synergically develop creative solutions together. Its potential use in schools raises two important questions: Firstly, what degree of structure and support is required to unleash student creativity and enhance learning - as in industry or does the student need more structured methods including explicitly being taught collaborative problem solving skills? Secondly, is CPS …
Understanding Different Approaches to ECE Pedagogy through Tensions
2021
Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland. The concept of pedagogy is the key to understanding pedagogy in early childhood education (ECE) in the Nordic countries, which are known for their high quality of life and education. However, in ECE, there are several different approaches toward pedagogy and it can be said that pedagogy is a multidimensional and dynamic concept. In this paper, the different approaches to pedagogy are defined and reconceptualized through an integrative literature analysis focusing on scientific papers and research reports of the concept. Five approaches to pedagogy were constructed: pedagogy through interaction, pedagogy through s…
Experiencing ethical retail ideology in the servicescape
2020
Studies of the ideological underpinnings of retail stores have improved our understanding of consumers’ retail experiences in brand and national ideology contexts. In retailing, ideology is manifested in retail spatial settings through tangible and intangible cues in servicescapes. This study expands our knowledge on ethical retail ideology by exploring how servicescapes convey cues that shape consumption experiences and foster ethical consumption. Data from an ethnographic study highlight how consumption experiences in physical retail spaces embedding a particular ethical ideology can be thematised as aesthetics, nostalgia and care. We show that the material and discursive aspects in servi…
Sbateyl.org: A Virtual Space for Effective Language Training
2016
AbstractThe paper presents an ongoing European cross-institutional project on teaching young language learners whose aim is to develop a web-based in-service teacher education programme with a school-based follow-up component. The main focus of the project is to bring researchers and teachers together to establish an innovative professional procedure blending theory and practice. Based on the strategic partnership between one local university and one primary school from each participant country, the project aims to foster the professional advancement and teaching practices of primary school teachers. The article initially outlines the main theoretical and methodological issues in the field …
First Stages of Adult Students Relationship to Scientific Knowing and Research in the Open University's Web-Based Methodology Course
2016
The adult students who participate in the web-based studies of the open university have in many ways heterogeneous starting points for studying and learning, for example, the educational backgrounds, the acquired work experience, the general academic skills and the objectives of the future can vary considerably. The adult students striving from the different starting points pursue their own individual objectives and the set educational dimensions of the academic education. In the academic adult education, individuality and the adult student's autonomy are emphasized and at the same time, diverse knowledge, skills and understanding are sought after. One key objective of the higher education …
Adult students in web-based thesis seminars : insights and challenges for supervision
2014
We examine the web-based thesis seminars in the context of academic adult education in our article which presents and reflects on the development of web-based teaching. Our reflection is based on our own web-based teaching experiences in the open university and in the class teachers' adult education programme aiming at the Master's degree, and in the feedback material that has been collected from the students. We first examine web-based seminars from the point of view of educational equality and accessible learning environments. Then we will analyse the requirement of scientificity of university context and the objectives related to the interaction and the adult educational solutions in web…
Practice for determining friction in hydraulic winch systems
2020
This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors based on data from the sub-supplier. The second step requires real-life testing, where the remaining friction losses in the winch system is identified and modeled. In this context, a practice is characterized by obtaining a friction loss estimation with the highest possible accuracy over the widest possible range of operating conditions with a limited amount of experimental work. The method benefits from the use of parametric models, sub-supplier data, and real-life meas…
IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security
2018
Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…
Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
