Using Activity Theory in Developing Instructional Tools for Project Management Studies

2014

Competence and skills of the project manager are significant to project success. The skills needed in project managers’ work cannot be learned only by reading the books or a lecture hall; one learns them by practice. Therefore, an important challenge for educational institutions is to develop pedagogical practices that allow students to participate in working life projects and to confront real-life problems. Project-based learning (PBL) offers a model that enables students to practice the skills and competences needed in working life projects by utilizing real-world work assignments in time-limited projects. Using PBL method alone does not necessarily guarantee learning result. In order to …

The Art-Based Methods in Developing Transversal Competence

2019

This article describes a project called “The art based methods in developing transversal competence” funded by The Finnish National Board of Education. The article is based on the hermeneutic phenomenological approach in action research. The project developed learning environments as well as project-based learning with emphasis on the art-based methods and transversal competence approach to learning. The aim was to develop unique and communal well-being in learning. The project offered tools to strengthen teachers’ professional skills to use expressive, art-based methods in different curriculum-based projects. The professional in-service training project included five contact days in six we…

From conceptualization to constructions in Finnish as an L2 : a case study

2017

AbstractThis study traces the individual learning trajectories of an adult beginner L2 Finnish learner in expressing the extralinguistic concept of evaluation from a dynamic usage-based perspective. Our results provide support for the view of learner language as a dynamic system in which patterns wax and wane and in which a change in one component has the potential to affect the whole system. In the early stages of learning there was a strong preference to use lexical verbs first, and then adjectives. The study also shows that variability plays a role. Finally, the study confirms that the learning of L2 constructions is in some cases item based. However, another highly frequent and superfic…

Lexically specific vs. productive constructions in L2 Finnish

2020

ABSTRACTIt is assumed from a usage-based perspective that learner language constructions emerge from natural language use in social interaction through exemplar learning. In L1, young learners have been shown to develop their constructions from lexically specific, formulaic expressions into more productive, abstract schemas. A similar developmental path has been shown for L2 development, with some exceptions. The aim of the current study is to explore to what extent the default assumption holds for L2 learning. The development of two constructions was traced in four adults learning L2 Finnish. Free-response data, collected weekly over a period of 9 months, were used to investigate the produ…

The resonant state at filling factor {\nu} = 1/2 in chiral fermionic ladders

2017

Helical liquids have been experimentally detected in both nanowires and ultracold atomic chains as the result of strong spin-orbit interactions. In both cases the inner degrees of freedom can be considered as an additional space dimension, providing an interpretation of these systems as synthetic ladders, with artificial magnetic fluxes determined by the spin-orbit terms. In this work, we characterize the helical state which appears at filling $\nu=1/2$: this state is generated by a gap arising in the spin sector of the corresponding Luttinger liquid and it can be interpreted as the one-dimensional (1D) limit of a fractional quantum Hall state of bosonic pairs of fermions. We study its main…

Dirakův kužel a pseudogapped hustota stavů v topologické polovině Heuslerovy sloučeniny YPtBi

2016

Topologické izolátory (Tis) jsou zajímavé materiály, které vykazují nebývalé vlastnosti. . Zde jsme prozkoumali sloučeniny YPtBi jako příklad ze třídy polovu-Heuslerových materiálů. Topological insulators (TIs) are exciting materials, which exhibit unprecedented properties, such as helical spinmomentum locking, which leads to large torques for magnetic switching and highly efficient spin current detection. Here we explore the compound YPtBi, an example from the class of half-Heusler materials, for which the typical band inversion of topological insulators was predicted. We prepared this material as thin films by conventional cosputtering from elementary targets. By in situ time-of-flight mo…

Measuring tourist satisfaction and dissatisfaction: adaptation of the 4Q methodology to the case of web based data

2019

Tourist satisfaction has been studied so far using many different theoretical approaches and measurement models. In doing that, scholars have considered satisfaction and dissatisfaction either as two extremes on a single continuum or two distinct conceptual dimensions, i.e. tourist satisfaction (TS) and tourist dissatisfaction (TD) (Alegre and Garau, 2010). In line with the latter approach, known as dual approach, the 4Q is a methodology which permits to measure TS and TD through the administration of just four open-ended questions to tourists (Oliveri et al., 2018). The main feature of the 4Q methodology is that data regarding dozens of TS and TD elementary indicators can be drawn from the…

Sand clams of Ganzirri marine coastal lagoon in Messina (Italy). Extraction and ICP-MS analysis

2008

This paper studies the possible forms or phases of heavy metals in sediments of a marine coastal lagoon, called Ganzirri, located in the Sicilian coast of the Messina’s strait by using sequential extraction. To reduce the extraction time of the Tessier method, the last step of speciation was carried out by mineralization in a microwave oven. Here we report the results of the distribution of As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, Se, Tl, V and Zn, in four fractions of sediments samples and the concentration of the same metals in clams. This study looked at three bivalve mollusc species, Tapes decussates, Chamelea gallina and Cardium edule, raised in the sediment considered and discussed the…

A New Perspective on the Relationship between Trading Variables and Volatility in Futures Markets

2017

In this paper, we study the relationship between trading-related variables and volatility in futures markets, from a new unifying perspective, which is based on the separation of open and closed positions. Volatility in stock index futures markets (Standard & Poor’s 500, DAX 30 and Nikkei 225) is related to the flow of contracts entered into the markets and the flow of contracts that are closed out. In general, the daily changes in the number of open and closed positions are both positively correlated with volatility. Additionally, there is a stronger positive relationship between the number of open (respectively, closed) positions and contemporaneous volatility on those days when t…
