An Information System Design Product Theory for Integrated Order, Transportation and Warehouse Management Systems

2013

Globalization, lead time reduction and cost pressures, and other factors make it nontrivial for most companies to devise and manage effective logistics services to meet client requirements. They are better off using the services of specialized third party logistics service providers. These providers compete fiercely and need to develop and improve their services continuously to gain competitive advantage. Integrating the logistics process for improving communication and coordination is the most feasible way for third party logistics providers to deal with these pressures. Yet, the extant literature provides little theoretical guidance for integrating the logistics life-cycle, including orde…

Efficient Time Integration of Maxwell's Equations with Generalized Finite Differences

2015

We consider the computationally efficient time integration of Maxwell’s equations using discrete exterior calculus (DEC) as the computational framework. With the theory of DEC, we associate the degrees of freedom of the electric and magnetic fields with primal and dual mesh structures, respectively. We concentrate on mesh constructions that imitate the geometry of the close packing in crystal lattices that is typical of elemental metals and intermetallic compounds. This class of computational grids has not been used previously in electromagnetics. For the simulation of wave propagation driven by time-harmonic source terms, we provide an optimized Hodge operator and a novel time discretizati…

Visualising maritime vessel open data for better situational awareness in ice conditions

2018

Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…

How news affect the trading behavior of different categories of investors in a financial market

2015

We investigate the trading behavior of a large set of single investors trading the highly liquid Nokia stock over the period 2003-2008 with the aim of determining the relative role of endogenous and exogenous factors that may affect their behavior. As endogenous factors we consider returns and volatility, whereas the exogenous factors we use are the total daily number of news and a semantic variable based on a sentiment analysis of news. Linear regression and partial correlation analysis of data show that different categories of investors are differently correlated to these factors. Governmental and non profit organizations are weakly sensitive to news and returns or volatility, and, typica…

Incompiuto, una nuova linea di partenza : progettare la differenza per un futuro sostenibile

2020

Le contemporanee costruzioni incompiute, fattispecie diffusa globalmente dell’ambiente costruito in abbandono, solo di recente sono uscite dal tabù in cui le relega l’ineludibile condizione di epifania di un fallimento. Senza entrare nel merito dei significati teoretici ad esse attribuiti (oscillanti tra i poli sovente mistificatori dell’esaltazione e della demonizzazione) e guardando alle tendenze individuabili in alcune realizzazioni degli ultimi lustri, l’articolo intende contribuire alla definizione di un approccio analitico e progettuale orientato ai multidimensionali obiettivi della sostenibilità, per rispondere in modo concreto a molteplici portatori di interesse e istanze della coll…

University Students’ Approaches to Making the Most of Their Study Time

2022

This article explores university students’ approaches to and positions with regard to making the most of their study time. The article discusses how various normative societal expectations around students’ use and management of time feature in their talk about how they organise their everyday lives. The research is based on thematic interviews (n = 28) that focused in detail on students’ day-to-day activities that were generated with students from two sets of generalist study fields in three regional Finnish universities. The results of a discursive analysis of students’ positionings reveal three discursive positions that represent of a variety in students’ approaches to make sense of the t…

Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk

2022

This study aimed to examine 1) adherence to 24-hour movement guidelines over a 2-year follow-up in children aged 6-8 years and 2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were assessed by a monitor combining heart rate and accelerometry measurements. Screen time was reported by the parents. Body fat percentage, waist circumference, blood glucose, serum insulin, plasma lipids and blood pressure were assessed, and a cardiometabolic risk score was calculated using z-scores. Children were classified as meeting the guidelines if they had on average ≥60min/day of moderate-to-vigorous physical activity during the valid days; ≤120min/day of screen…

Rosyjska memuarystyka kobieca XIX wieku we współczesnych zainteresowaniach badawczych

2019

The article is devoted to contemporary studies on the nineteenth century memoirs written by Russian women. In the nineteenth century women’s memoirs were underestimated and neglected by researchers. Recently, there has been a significant increase in research interest in memoirs written by women. This subject has been taken up by literary scholars, historians, experts on cultural studies and anthropologists. A. Bielova, I. Savkina, W. Laszczak, K. Kosowska, N. Pushkariova, A. Fieduta, W. Ponomarieva, L. Khoroshilova, J. Prikazchikova, A. Stankewich, J. Samofalova, O. Mamaieva, S. Tatarkina are among those who are interested in it. Memoirs are a valuable source of information about the epoch,…
