STUDENTS’ READINESS FOR MASSIVE OPEN ONLINE COURSES (MOOCS) IN LATVIA
2020
MOOCs have gained popularity increasingly more and more with their open online approach and mass engagement. They could play an important role in higher education. But the question remains whether students are ready for it. The aim of the study was to find out what students' understanding of online learning was and to what extent they were prepared for MOOCs. A research question was raised: there is a relationship among technical competencies, socio-communication competencies, self-efficacy, self-directedness and MOOCs readiness. The survey-monkey's electronic platform was used for data extraction. Open-ended questions were asked on the 4-point Likert scale. According to the research questi…
Socio-technical Congruence Sabotaged by a Hidden Onshore Outsourcing Relationship: Lessons Learned from an Empirical Study
2012
Despite the popularity of outsourcing arrangements, distributed software development is still regarded as a complex endeavor. Complexity primarily comes from the challenges in communication and coordination among participating organizations. In this paper we discuss lessons learned from participatory research carried out in a highly distributed onshore outsourcing project. Previous research established that socio-technical congruence principles alleviate distributed work. In practice we have found that alignment between the systems structure and organizational structure can be studied from different abstraction levels and also during different phases of project lifecycle. We have found that…

On the Consistent Use of VaR in Portfolio Performance Evaluation: A Cautionary Note
2010
The portfolio performance measures based on the Value at Risk (VaR) concept have gained widespread popularity and are often used in empirical studies. In the majority of empirical studies, however, a VaR-based performance measure is inconsistently used. In this article, Zakamouline emphasizes how to consistently use VaR in portfolio performance evaluation. He also elaborates on a simple framework that allows the derivation of a general formula for a portfolio performance measure that is not limited to the use of VaR-based reward and risk measures, but is valid for all reward and risk measures that satisfy a few plausible properties.
Ranking farms with a composite indicator of sustainability
2011
The assessment of sustainability at farm level has been growing in popularity over the last few years. This article contributes to this line of research by building up composite indicators for different facets—social, economic, environmental, and global—of farm sustainability using a methodological approach that combines data envelopment analysis (DEA) and multicriteria decision making (MCDM) methods, and assigns common weights to each individual sustainability indicator. This approach is applied to a database of 163 farms located in the Campos County, a region belonging to the dry lands of the Spanish Northern Plateau, using 12 individual indicators of sustainability. Our findings show tha…
Morally Successful Collaboration between Academia and Industry — A Case of a Project Course
2006
Academia-industry collaboration is common in the IT-field, and it includes training programs, research centre activities, and industry advisory boards (Watson and Huber 2000). For the industry, co-operation provides possibilities to acquire human resources and, for the academia, co-operation ensures that research and teaching activities are relevant. Regardless of its popularity little is known about moral issues relating to this phenomenon. This study intends to fill the gap in knowledge by determining the nature of moral conflicts perceived by clients, students, and instructors of a collaborative project course, and by formulating a framework to successfully getting grips with these confl…
Tinker, Tailor…: Creativity in Foreign Language Learning and Teaching
2017
The word creativity has recently won great popularity in numerous contexts, showing both positive (“creative writing”) and negative (“creative accounting”) connotations. The concept itself has many meanings as it may refer to the end product of one’s activity, the cognitive processes involved in the creative act, the personality of a creative person, the development of creativity across the life span, and also the factors that either stimulate or inhibit the process of creation (Łukasik, 2015; Simonton, 2000). There is also a distinction between exceptional creativity, manifesting itself in important works that are significant for a given society, and everyday creativity, which can be obser…
What determines a positive attitude towards natural food products? An expectancy theory approach.
2021
Natural food products are becoming increasingly popular worldwide due to their health and environmental benefits. However, these products' increasing anecdotal popularity has not translated into their widespread adoption; in fact, demand for natural food products remains confined to a relatively small segment of consumers. Despite this, little is known about the facilitators and inhibitors of favourable attitude of consumers towards these products. Recognising this gap, our study employed the theoretical lens of expectancy theory to investigate these factors. Through an extensive review of the pro-environmental consumption literature, we identified four facilitating and inhibiting factors: …
Adaptive Task Assignment in Online Learning Environments
2016
With the increasing popularity of online learning, intelligent tutoring systems are regaining increased attention. In this paper, we introduce adaptive algorithms for personalized assignment of learning tasks to student so that to improve his performance in online learning environments. As main contribution of this paper, we propose a a novel Skill-Based Task Selector (SBTS) algorithm which is able to approximate a student's skill level based on his performance and consequently suggest adequate assignments. The SBTS is inspired by the class of multi-armed bandit algorithms. However, in contrast to standard multi-armed bandit approaches, the SBTS aims at acquiring two criteria related to stu…
Popularity of patterns over $d$-equivalence classes of words and permutations
2020
Abstract Two same length words are d-equivalent if they have same descent set and same underlying alphabet. In particular, two same length permutations are d-equivalent if they have same descent set. The popularity of a pattern in a set of words is the overall number of copies of the pattern within the words of the set. We show the far-from-trivial fact that two patterns are d-equivalent if and only if they are equipopular over any d-equivalence class, and this equipopularity does not follow obviously from a trivial equidistribution.
