Towards Evidence-Based Academic Advising Using Learning Analytics
2018
Academic advising is a process between the advisee, adviser and the academic institution which provides the degree requirements and courses contained in it. Content-wise planning and management of the student’ study path, guidance on studies and academic career support is the main joint activity of advising. The purpose of this article is to propose the use of learning analytics methods, more precisely robust clustering, for creation of groups of actual study profiles of students. This allows academic advisers to provide evidence-based information on the study paths that have actually happened similarly to individual students. Moreover, academic institutions can focus on management and upda…
Visual Parameter Selection for Spatial Blind Source Separation.
2022
Analysis of spatial multivariate data, i.e., measurements at irregularly-spaced locations, is a challenging topic in visualization and statistics alike. Such data are inteGral to many domains, e.g., indicators of valuable minerals are measured for mine prospecting. Popular analysis methods, like PCA, often by design do not account for the spatial nature of the data. Thus they, together with their spatial variants, must be employed very carefully. Clearly, it is preferable to use methods that were specifically designed for such data, like spatial blind source separation (SBSS). However, SBSS requires two tuning parameters, which are themselves complex spatial objects. Setting these parameter…
Interactivized : Visual Interaction for Better Decisions with Interactive Multiobjective Optimization
2022
In today’s data-driven world, decision makers are facing many conflicting objectives. Since there is usually no solution that optimizes all objectives simultaneously, the aim is to identify a solution with acceptable trade-offs. Interactive multiobjective optimization methods are iterative processes in which a human decision maker repeatedly provides one’s preferences to request computing new solutions and compares them. With these methods, the decision maker can learn about the problem and its limitations. However, advanced optimization software usually offer simple visualization tools that can be significantly improved. On the other hand, current approaches for multiobjective optimization…
Big data and HR analytics in the digital era
2019
Purpose The purpose of this paper is to focus on how the HR function takes advantage of human resource analytics (HRA), including big data (BD), and discuss factors hindering HRA and data utilization. Moreover, the authors discuss the implications of the HRA-induced role transformation of the human resource (HR) function. Design/methodology/approach This is an explorative case study based on qualitative interviews in nine leading Finnish companies. Findings The results indicate that both technical and human obstacles, operating with very basic HR processes and traditional information systems and poor data quality, hinder adoption of advanced HRA. This, combined with lacking skills in analy…
SWOT-analyysin soveltaminen yrityksen kyberturvallisuuden tilannekuvan muodostamiseen : Cyber Trust/CIRP-raportti : tutkimusmenetelmän kuvaus 2017
2018
Modernin yhteiskunnan toiminta perustuu useiden kriittisten infrastruktuurien yhteistoimintaan. Niiden keskinäinen toimintakyky riippuu yhä enemmän luottamuksesta infrastruktuuriin kuuluvien organisaatioiden toimintakykyyn kybertoimintaympäristössä, jonka riskejä digitaalisen maailman uhkakuvat jatkuvasti kasvattavat. SWOT-analyysi on tärkeä väline analysoitaessa organisaation toimintakykyä ja sen toimintaympäristöä kokonaisuutena. Se on nelikenttämenetelmä, jota käytetään yleisesti tilannekuvan muodostamiseen laadittaessa yrityksen strategioita, sekä oppimisen tai ongelmien tunnistamisessa, arvioinnissa ja toimintaprosessien kehittämisessä. SWOTanalyysin kohteena voi olla jonkin yrityksen …

Instrumentation for time-of-flight elastic recoil detection analysis
2016
Time-of-flight elastic recoil detection is an ion beam based method to analyze the elemental composition of thin film samples at different depths. In order to improve the mass resolution and to enable kinematic correction a position sensitive gas ionization chamber energy detector was constructed. This detector along with pre-existing timing detectors were connected to a modern fully digitizing data acquisition setup. This thesis describes the design of these instruments, including all aspects from the mechanical design of the gas ionization detector to the algorithm and software development of the digitizing acquisition setup. The performance of the system has been studied with measurements …
