Online and face-to-face role-play simulations in promoting social work students’ argumentative problem-solving

2013

This paper reports on a teaching experiment in which social work students (n=38) practiced problem solving through argumentative tasks. A teaching experiment was carried out at a Mikkeli University of Applied Sciences in Finland in connection with a course concerning preventative work against alcohol- and drug abuse. This quasiexperimental study investigated whether role-play simulation conducted either online (15 students) or face-to-face (14 students) improved students’ problem solving on social issues. As a pre-test, the students wrote an essay after having watched a dramatization of problematic cases on elderly people’s use of alcohol. The students also attended lectures (30 x 45 min) o…

Investigating the success of ERP systems in Pakistan : end-users' perspective

2016

The global business environment is changing rapidly, and organisations from developing countries such as Pakistan have to re-engineer their business processes to meet the challenges of increased competition and rising customer expectations. Enterprise resource planning (ERP) systems intend to deliver many benefits, such as business automation, reduced operating costs, accurate demand forecasts, better decision-making and improved customer service. However, organisations adopting ERP systems encounter many types of problems that may lead to failures in processes, expectations and interactions. In order to address these failures, researchers have identified the critical success factors in the…

Sosiaalialan ammattilaiset halukkaita osallistumaan asiakastietojärjestelmien kehittämiseen – osallistumistavoissa kehitettävää

2020

Tietojärjestelmien kehittämistyön lähtökohtana tulee olla vahva ymmärrys käyttäjien tarpeista, tehtävistä sekä toimintaympäristöstä. Lisäksi suunnitteluratkaisuja tulee arvioida käyttäjien kanssa kehittämisprosessin aikana ja käyttöönoton jälkeen. Vaikka kansallisesti kohdennetaan runsaasti resursseja tietojärjestelmäpalveluiden kehittämiseen, sosiaalialalta tutkimusta aiheesta löytyy niukasti. Sosiaalialan ammattilaisten kokemuksia asiakastietojärjestelmien kehittämistyöstä kartoitettiin osana keväällä 2019 toteutettua valtakunnallisesta käyttäjäkokemuskyselyä. Kysymyksissä käsiteltiin kokemuksia yhteistyöstä tietojärjestelmätoimittajan kanssa, osallistumisesta kehittämistyöhön ja osallist…

Is There Any Hope for Developing Automated Translation Technology for Sign Languages?

2021

This article discusses the prerequisites for the machine translation of sign languages. The topic is complex, including questions relating to technology, interaction design, linguistics and culture. At the moment, despite the affordances provided by the technology, automated translation between signed and spoken languages – or between sign languages – is not possible. The very need of such translation and its associated technology can also be questioned. Yet, we believe that contributing to the improvement of sign language detection, processing and even sign language translation to spoken languages in the future is a matter that should not be abandoned. However, we argue that this work shou…

Problems and Issues in Translating International Educational Achievement Tests

2013

The article reviews research and findings on problems and issues faced when translating international academic achievement tests. The purpose is to draw attention to the problems, to help to develop the procedures followed when translating the tests, and to provide suggestions for further research. The problems concentrate on the following: the unique and demanding purpose of the translation task, the partly contradictory task specifications and translation instructions, the indecision as to whether to produce one or two target versions, the indecision as to whether to use one or two source versions, inadequate revision and verification, deficient translator competences, and a lack of time.…

Requirements for using simulation to design and assess wireless ATM handover solutions

1999

Wireless ATM (WATM) has been widely considered as a solution for broadband wireless services. Handover is one of the most important mobility support functions in the WATM network. Many handover solutions have been proposed, analysed, and benchmarked. Simulations have been broadly used to assess these solutions. However, there are many dilemmas in how simulation has been applied as a research methodology: heterogeneous simulation systems used, lack of comparison with other related work, biased conclusions, and unavailability of simulation models and systems to researchers. The WATM research community lacks a standard and commonly acceptable methodology for applying simulation. To address thi…

Analysis of the performance of the TES algorithm over urban areas

2014

International audience; The temperature and emissivity separation (TES) algorithm is used to retrieve the land surface emissivity (LSE) and land surface temperature (LST) values from multispectral thermal infrared sensors. In this paper, we analyze the performance of this methodology over urban areas, which are characterized by a large number of different surface materials, a variability in the lowest layer of the atmospheric profiles, and a 3-D structure. These specificities induce errors in the LSE and LST retrieval, which should be quantified. With this aim, the efficiency of the TES algorithm over urban materials, the atmospheric correction, and the impact of the 3-D architecture of urb…

Hydro-mechanical analysis of volcanic ash slopes during rainfall

2016

Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Owing to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach for the analysis of wetting-induced instability phenomena at the onset of failure in loose volcanic ash slopes. A numerical simulation of a landslide-prone volcanic slope in Costa Rica is carried out with a two-dimensional hydro-mechanical finite-element slope model. A constitutive model based on the effective stress concept extended to partially saturated conditions is used to reproduce the volcanic ash hydro-mechanical behaviour. The m…
