How does serendipity affect diversity in recommender systems? A serendipity-oriented greedy algorithm
2018
Most recommender systems suggest items that are popular among all users and similar to items a user usually consumes. As a result, the user receives recommendations that she/he is already familiar with or would find anyway, leading to low satisfaction. To overcome this problem, a recommender system should suggest novel, relevant and unexpected i.e., serendipitous items. In this paper, we propose a serendipity-oriented, reranking algorithm called a serendipity-oriented greedy (SOG) algorithm, which improves serendipity of recommendations through feature diversification and helps overcome the overspecialization problem. To evaluate our algorithm, we employed the only publicly available datase…
Aalto-1, multi-payload CubeSat: Design, integration and launch
2021
The design, integration, testing, and launch of the first Finnish satellite Aalto-1 is briefly presented in this paper. Aalto-1, a three-unit CubeSat, launched into Sun-synchronous polar orbit at an altitude of approximately 500 km, is operational since June 2017. It carries three experimental payloads: Aalto Spectral Imager (AaSI), Radiation Monitor (RADMON), and Electrostatic Plasma Brake (EPB). AaSI is a hyperspectral imager in visible and near-infrared (NIR) wavelength bands, RADMON is an energetic particle detector and EPB is a de-orbiting technology demonstration payload. The platform was designed to accommodate multiple payloads while ensuring sufficient data, power, radio, mechanica…
Introducing Continuous Time Meta-Analysis (CoTiMA)
2019
Meta-analysis of panel data is uniquely suited to uncovering phenomena that develop over time, but extant approaches are limited. There is no straightforward means of aggregating findings of primary panel studies that use different time lags and different numbers of waves. We introduce continuous time meta-analysis (CoTiMA) as a parameter-based approach to meta-analysis of cross-lagged panel correlation matrices. CoTiMA enables aggregation of studies using two or more waves even if there are varying time lags within and between studies. CoTiMA thus provides meta-analytic estimates of cross-lagged effects for a given time lag regardless of the frequency with which that time lag is used in p…
Galaxy-SynBioCAD: Synthetic Biology Design Automation tools in Galaxy workflows
2020
AbstractMany computer-aided design tools are available for synthetic biology and metabolic engineering. Yet, these tools can be difficult to apprehend, sometimes requiring a level of expertise that limits their use by a wider community. Furthermore, some of the tools, although complementary, rely on different input and output formats and cannot communicate with one another. Scientific workflows address these shortcomings while offering a novel design strategy. Among the workflow systems available, Galaxy is a web-based platform for performing findable and accessible data analyses for all scientists regardless of their informatics expertise, along with interoperable and reproducible computat…
Pronunciation Learning Strategy Chains: A Qualitative Approach
2014
Language learning is a daunting process frequently enhanced by a number of factors, for example, language learning strategies deployed in an orchestrated manner (Oxford 1990). Similarly, pronunciation learning may be supported by effective strategies used either separately or in logically combined chains. However, little attention has been given so far to the strategies L2 learners employ when learning the target language pronunciation, not to mention pronunciation learning strategy chains. Hence, there have been a limited number of empirical investigations into pronunciation learning strategies (PLS) in general and in particular the ones following the qualitative design (cf. Bukowski 2004;…
Research opportunities in performance measurement in public utilities regulation
2015
Purpose – The purpose of this paper is to propose a method to choose a set of scientific articles about performance measurement in public utilities regulation. The method is designed to identify references with high academic relevance in databases accessed via the internet, and, through these articles, to perform a mapping of these publications and conduct a systemic analysis. Design/methodology/approach – The study is characterized as exploratory and descriptive with a qualitative and quantitative approach. Incorporates an inductive logic, and draws on primary and secondary data sources. The research involves the application of a technical procedure for selection and study of selected art…
Universal design as resilient urban space plan strategy. New scenarios for environmental resources’ sustainable management
2021
Nowadays, urban framework, stressed by the growing anthropic pressure and its constantly evolving use requests is split by uneven structures, contexts, users and patchy needs, which come out to be inefficient and ineffective in access and management. This fact is directly connected both with morph-functional structure of urban texture and its continuous changing trends. The most important consequences of this situation are some negative effects that produce entropy, mistaken anthropic space uses, ecological networks decrease and most of all a substantial urban life quality reduction connected with mobility problems and non-resilient spaces' use at the different plan scales. These elements m…
A HOLISTIC MULTI-METHODOLOGY FOR SUSTAINABLE RENOVATION
2019
A review of the barriers for building renovation has revealed a lack of methodologies, which can promote sustainability objectives and assist various stakeholders during the design stage of building renovation/retrofitting projects. The purpose of this paper is to develop a Holistic Multi-methodology for Sustainable Renovation, which aims to deal with complexity of renovation projects. It provides a framework through which to involve the different stakeholders in the design process to improve group learning and group decision-making, and hence make the building renovation design process more robust and efficient. Therefore, the paper discusses the essence of multifaceted barriers in buildin…
Strategic Leadership and Leaders in Entrepreneurial Contexts: A Nexus for Innovation and Impact Missed?
2015
Research at the nexus of strategic leadership and entrepreneurial contexts has been encouraging, but some of the more innovative and impactful questions remain underexplored. The purpose of the Special Issue was to provide a forum for works that build on the constraints, challenges, characteristics, and other salient elements of entrepreneurial settings to advance theory and testing on strategic leadership effects, as well as enrich our understanding of firm behaviour and outcomes in entrepreneurial contexts. We first provide an overview and background of the Special Issue. We then provide a summary of the process and outcomes, including a synopsis of the accepted manuscripts. The discussio…
Distributed pedagogical leadership and generative dialogue in educational nodes
2012
The article presents practices of distributed pedagogical leadership and generative dialogue as a tool with which management and personnel can better operate in the increasingly turbulent world of education. Distributed pedagogical leadership includes common characteristics of a professional learning community when the educational actors intentionally share a common mission. There, all stakeholders take collective responsibility for students' learning. Generative dialogue is a way to negotiate in this realm in generating new knowledge and understanding. To introduce this process in practice, the article describes two Finnish learning environments where the stakeholders define, first, the c…
