Negotiating the symbolic power of information and communication technologies (ICT): The spread of Internet-supported distance education
2009
Submitted version of an article in the journal: Information Technology for Development The deposited fulltext is a preprint of the definitive article at Wiley Interscience http://dx.doi.org/10.1002/itdj.20110 The Internet may be, as typically suggested, important in distance education for facilitating connections between groups of students, educational institutions, and external learning resources. This article, however, reveals why this is not the only reason for applying information and communication technologies (ICT) in higher education in a remote area in a developing country. In addition, the Internet seems to be of great importance in symbolizing modernization and progress, thereby a…
On the relationship between knowledge creation and economic performance
2015
An empirical two-equation dynamic panel-data model system with fixed effects is proposed to analyze the relationship between knowledge creation and economic performance across regions over time. Estimates of the model for Spanish regions show that (i) knowledge creation depends on local R&D effort, on the amount of knowledge in use, and on knowledge creation in neighboring regions; and (ii) assimilation of new knowledge depends on local knowledge creation and on assimilation of knowledge in neighboring regions. Both processes include region-specific context fixed effects and region-specific time effects, representing region-specific dynamic influences. The results imply that (a) efficie…
Continuous Improvement Challenges: Implementing PBL in One University in Romania
2020
Abstract What do business and education have in common when it comes to continuous improvements? The answer is Lean Principles. Case studies and implementation challenges from some pilot PBL projects in one university, in Romania, are analysed and described in depth, while comparing the educational experience in the university to the challenges and resistance to change that facilitators in the private sector face inside their own companies. Taking this into consideration and based on qualitative data retrieved from interviews carried out in the private sector and in the educational sector, the authors of this paper will present deep insights that are meant to serve as a basis for understand…
Agility and system documentation in large-scale enterprise system projects: a knowledge management perspective
2021
Abstract The growth of the agile approach usage comes with a deemphasis on formal documentation (explicit knowledge) and an increased reliance on personal interactions (tacit knowledge) for knowledge transfer. However, the sharing of tacit knowledge poses challenges. The agile approach is prone to knowledge hoarding, as well as knowledge loss from employee turnover and reassignment during periods of significant organizational changes. This study proposes a model that frames documentation and personal interactions as co-agents of system knowledge transfer. We report the preliminary confirmation of crucial antecedents along the dimensions of codification and personalization strategies to supp…
Internal vs. external R&D teams: Evidences from the Italian wine industry
2021
R&D teams' internationalization attracts interests from different research-streams. However, the decision on what type of R&D structure is more convenient to invest in may differ, based on several factors, such as risk-taking propensity and internal resource availability. With an aim to enrich the extant literature and to provide practical insights for managers working in the wine industry, this case study explores the determinants of an Italian family-owned winery that attempts to keep a balance between its internal and external R&D teams' decision, using an integrated theoretical framework based on the transaction costs and the resource-based view theory. The optimal R&D s…
Vibrasjonsanalyse : Feildeteksjon i Kulelager: Prosessering av Vibrasjonssignaler, Algoritmer, og Envelope Spektrum
2017
Masteroppgave fornybar energi ENE500 - Universitetet i Agder 2017 The report deals with fault detection and diagnosis of roller element bearings. Vibration and shaft position sensor data combined with three algorithms are tested to determine which combination may detect bearing faults early and reliably. Experimental data from an accelerated life-time test is used to verify the performance. Results show that the vibration signal combined with a fast spectral correlation algorithm yields the most reliable diagnosis.
Can Differences in Characteristics Explain Ethnic Wage Gap in Latvia?
2017
Abstract We used anonymized micro data from Labour Force Survey to estimate the ethnic wage gap in Latvia and find the factors that explain it. We found that a notable ethnic wage gap still exists in Latvia with non-Latvians earning 10 % less than Latvians in 2015. The results of Oaxaca-Ransom decomposition show that approximately two thirds of the ethnic wage gap are explained by differences in characteristics with the most important effects in favour of Latvians caused by segregation in better paying occupational groups, having Latvian citizenship and better education (higher education levels and more favourable segregation by education fields). This was partly offset by favourable segreg…
FORECASTING THE LABOUR FORCE DEMAND AND SUPPLY IN LATVIA / LATVIJOS DARBO JĖGOS PAKLAUSOS IR PASIŪLOS MODELIAVIMAS
2008
The purpose of this paper is to analyse the problems of Latvian labour market and its possible development. An econometric model for labour force demand and supply forecasting is elaborated and it comprises 120 professions, 37 aggregated groups of professions and covers time period 2007–2030. The results of the quantitative and qualitative Employers’ Survey are analysed and taken into account. The novelty of this research study lies in the complex approach to the labour force demand and supply analyses and to the forecasts to the Latvian economy in general and for its 15 separate sectors. Santrauka Šio straipsnio tikslas – išanalizuoti Latvijos darbo rinkos problemas ir galimus pokyčius. Su…
Monitoring Coastal Lagoon Water Quality Through Remote Sensing: The Mar Menor as a Case Study
2019
The Mar Menor is a hypersaline coastal lagoon located in the southeast of Spain. This fragile ecosystem is suffering several human pressures, such as nutrient and sediment inputs from agriculture and other activities and decreases in salinity. Therefore, the development of an operational system to monitor its evolution is crucial to know the cause-effect relationships and preserve the natural system. The evolution and variability of the turbidity and chlorophyll-a levels in the Mar Menor water body were studied here through the joint use of remote sensing techniques and in situ data. The research was undertaken using Operational Land Imager (OLI) images on Landsat 8 and two SPOT images, bec…
