A mission for grammar writing : early approaches to Inuit (Eskimo) languages
The Inuit inhabit a vast area of--from a European point of view--most inhospitable land, stretching from the northeastern tip of Asia to the east coast of Greenland. Inuit peoples have never been numerous, their settlements being scattered over enormous distances. But nevertheless, from an ethnological point of view, all Inuit peoples shared a distinct culture, featuring sea mammal and caribou hunting, sophisticated survival skills, technical and social devices, including the sharing of essential goods and strategies for minimizing and controlling aggression
UNDERSTANDING THE INFLUENCE OF TECHNOSTRESS ON WORKERSâ JOB SATISFACTION IN GIG-ECONOMY: AN EXPLORATORY INVESTIGATION
Gig-economy is a recent concept that has been attracting growing attention. Online labour markets (OLMs) are a prominent part of gig-economy and require completion of tasks digitally through platforms such as MTurk and Upwork. The World Bank estimated the total market size of OLMs to be 25 billion in 2020. Despite the rapid growth of OLMs, the implications of workersâ wellbeing in such markets are not well understood and highly debated. A report commissioned by EU-OSHA has identiïŹed psycho-social risks associated with the work in OLMs. The highly competitive and fast-paced nature of OLMs necessitates workers to multitask and perform intense technology-enabled work which may lead to technostress. This paper investigates workersâ job satisfaction in OLMs using technostress and job characteristic theories with the aim of providing an in-depth understanding of the experiences and perceptions of workers. Our research model has both theoretical and practical implications which will help to diagnose potential problems and improve the wellbeing of workers by formulating strategies for OLMs and workers. The paper presents the results of a pilot study in a popular OLM using structural equation modelling
A Multi-Dimensional Measurement Model for Assessing the Pre-Adoption of Open Learner Models in Technology-Mediated Teaching and Learning: A Pilot Study
Visualizing learnersâ information through the development of open learner models for improving the effectiveness of teaching and learning has attracted much attention in technology-mediated learning. There is, however, a lack of research in exploring the acceptance of open learner models in the pre-adoption of this model. This paper develops a multi-dimensional measurement model for assessing the pre-adoption of open learner models from the learnersâ perspective. A pilot study is carried out to confirm the reliability and validity of the measurement model based on the data collected from 300 respondents using an online survey distributed in a higher education institution in Malaysia. This model provides a useful set of guidelines for educational institutions in developing efficient and effective policies to promote the adoption of open learner models in technology-mediated learning towards improving the performance of technology-mediated teaching and learning
Robert Zimmermann and Herbartianism in Vienna. The critical reception from Brentano and his followers
This study is about an aspect of the reception of Herbatianism in Austria which has not been thoroughly investigated so far. It pertains to a controversy opposing Robert Zimmermann and Franz Brentano in the context of discussions which took place in the Philosophical Society of the University of Vienna. This study looks more specifically at three important episodes involving the Philosophical Society, first, the controversy over Herbartianism, second that over the evaluation of Schellingâs philosophy, and finally the reception of Bolzano in Austria. I will first describe the circumstances that led Zimmermann to get involved in the Philosophical Society and the source of his controversy with Brentano and his followers. I will then comment Zimmermannâs address as chairman of the Philosophical Society and Brentanoâs reaction to Zimmermannâs remarks on Schelling and the historical period to which he belongs. I will complete my analysis of Brentanoâs reaction with a summary of his evaluation of Herbartâs philosophical program to which Zimmermann adhered. The last part focuses on Zimmermannâs decisive role in the reception of Bolzano in Vienna in connection with the Bolzano Commission established by the Philosophical Society. I will conclude with brief remarks on Zimmermannâs legacy in Vienna
Can digital libraries generate knowledge?
"This paper argues that the information processing paradigm which is still fundamental to digital library engineering is not adequate for the way in which information and informational objects - as stored in Digital Library systems - should be treated. The recent move within information science towards emancipation from the Shannon/ Weaver information theory concept provides some indications of how Digital Libraries could be conceptualized in a way that has not yet been implemented in standardized formal frameworks such as the DELOS or the 5S-Framework. A deeper understanding of information processes beyond the concepts and usage of such systems could help to make better use of the enormous potential and resources in the field of Digital Library engineering. Resulting effects could be the way in which knowledge transfer and acquisition processes are supported by adequate interfaces and, subsequently, by new ways of embedding collections in communities of information practice, such as research teams or learning groups."

MOOClm: Learner Modelling for MOOCs
Massively Open Online Learning systems, or MOOCs, generate enormous quantities of learning data. Analysis of this data has considerable potential benefits for learners, educators, teaching administrators and educational researchers. How to realise this potential is still an open question. This thesis explores use of such data to create a rich Open Learner Model (OLM). The OLM is designed to take account of the restrictions and goals of lifelong learner model usage. Towards this end, we structure the learner model around a standard curriculum-based ontology. Since such a learner model may be very large, we integrate a visualisation based on a highly scalable circular treemap representation. The visualisation allows the student to either drill down further into increasingly detailed views of the learner model, or filter the model down to a smaller, selected subset. We introduce the notion of a set of Reference learner models, such as an ideal student, a typical student, or a selected set of learning objectives within the curriculum. Introducing these provides a foundation for a learner to make a meaningful evaluation of their own model by comparing against a reference model. To validate the work, we created MOOClm to implement this framework, then used this in the context of a Small Private Online Course (SPOC) run at the University of Sydney. We also report a qualitative usability study to gain insights into the ways a learner can make use of the OLM. Our contribution is the design and validation of MOOClm, a framework that harnesses MOOC data to create a learner model with an OLM interface for student and educator usage
Macroscale multimodal imaging reveals ancient painting production technology and the vogue in Greco-Roman Egypt.
Macroscale multimodal chemical imaging combining hyperspectral diffuse reflectance (400-2500ânm), luminescence (400-1000ânm), and X-ray fluorescence (XRF, 2 to 25âkeV) data, is uniquely equipped for noninvasive characterization of heterogeneous complex systems such as paintings. Here we present the first application of multimodal chemical imaging to analyze the production technology of an 1,800-year-old painting and one of the oldest surviving encaustic ("burned in") paintings in the world. Co-registration of the data cubes from these three hyperspectral imaging modalities enabled the comparison of reflectance, luminescence, and XRF spectra at each pixel in the image for the entire painting. By comparing the molecular and elemental spectral signatures at each pixel, this fusion of the data allowed for a more thorough identification and mapping of the painting's constituent organic and inorganic materials, revealing key information on the selection of raw materials, production sequence and the fashion aesthetics and chemical arts practiced in Egypt in the second century AD
Methods of concept analysis - towards systematic concept analysis (part 2 of 3)
This article is the second one in a series of three articles which focus on comparison and development of concept analysis methods as an academic research method. In the first article, terminological analysis methods â originally developed for practical terminology work â were contrasted with selected concept analysis methods developed in business studies and nursing science. Based on the comparison, the second article discusses a further development of terminological methods towards what is here called 'systematic concept analysis', and outlines steps that can be taken when analysing concepts for various purposes. The systematic concept analysis method is based on terminological methods and thus lays emphasis on clarifying the relations between concepts and locating concepts in concept systems â also in the case where a single concept is taken as a research object. The third article will describe concept analysis tools in more detail.© 2010 The Author(s).fi=vertaisarvioitu|en=peerReviewed
