Changes in personal work goals in relation to the psychosocial work environment: A two-year follow-up study
2011
Associations between changes in the psychosocial work environment and changes in personal work goals were investigated in a two-wave, two-year longitudinal study. Psychosocial work environment was studied within the context of the Effort–Reward Imbalance model (ERI; Siegrist, 1996). The participants consisted of 423 young Finnish managers. Their most important personal work goals were categorized into seven content categories of competence, progression, well-being, job change, job security, organization, and finance at both measurement times. There were differences, especially in changes in the career opportunities factor of reward, between participants whose goals changed during the study.…
About some difficulties with the functional forms of Lorenz curves
2022
We study to what extent some functional form assumption on the Lorenz curve are amenable to calculating headcount poverty, or poverty threshold, the key concept to determine a poverty index. The difficulties in calculating it have been underestimated. We must choose some functional forms for the Lorenz concentration curve. We examine three families of one-parameter functional forms to estimate Lorenz curves: power (elementary and Pareto), exponential (elementary and Gupta) and fractional (Rohde). Computing these numerical functions may be difficult and impose some restrictions on their domain of definition, may impose to use some numerical approximation methods. The elementary power and exp…
El valor del establecimiento y su relación con la imagen de marca privada: efecto moderador del conocimiento de la marca privada como oferta propia d…
2013
ResumenEl presente trabajo plantea como objetivo conocer cómo afecta la imagen de marca privada a la formación del valor de marca del establecimiento; en el estudio de esta relación cobra especial consideración la posible influencia del conocimiento de la marca privada como oferta propia del establecimiento. Desde una perspectiva empírica, se analizan los establecimientos Decathlon, a partir de la opinión de 300 consumidores. Los resultados obtenidos en la investigación muestran la importancia de fortalecer una imagen de marca privada positiva y favorable, como medio para la construcción de una sólida imagen de la tienda que, a su vez, también repercute en la creación del valor del establec…
Dynamic Resource Allocation and Computation Offloading for Edge Computing System
2020
In this work, we propose a dynamic optimization scheme for an edge computing system with multiple users, where the radio and computational resources, and offloading decisions, can be dynamically allocated with the variation of computation demands, radio channels and the computation resources. Specifically, with the objective to minimize the energy consumption of the considered system, we propose a joint computation offloading, radio and computational resource allocation algorithm based on Lyapunov optimization. Through minimizing the derived upper bound of the Lyapunov drift-plus-penalty function, the main problem is divided into several sub-problems at each time slot and are addressed sepa…
Teori i praksis - praksis i teori. GLU-studenters refleksjoner om fag og didaktikk
2017
De siste tiars forskning, samfunnsdebatt og politikkutforming knyttet til skolesektoren har vaert preget av diskusjoner om hva det egentlig innebaerer a vaere en kompetent laerer, og hvordan de to laeringsarenaene i laererutdanningene – teoriarenaen og praksisarenaen – best kan utfylle hverandre for a utdanne kompetente laerere. I denne artikkelen presenterer vi resultatene fra en undersokelse blant grunnskolelaererstudenter pa en utdanningsinstitusjons grunnskolelaererutdanning for 1.–7. trinn. I undersokelsen har vi rettet blikket mot studentenes opplevelser av laererrollen og av sammenhengen mellom teoriarenaen og praksisarenaen. Dette har vi gjort i tilknytning til ett spesifikt undervi…

The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedente…
ERP in small service companies
2013
The purpose of this thesis was to provide knowledge on the organizational and performance consequences of management control systems. The examination into prior literature yielded information on the benefits and challenges related to ERP systems, the position of ERP systems in the overall control environment of the company, and how ERP influences the ensemble of management control systems. By leaning to the prior work of Chapman and Kihn (2009), a survey research was conducted aiming to discover if information system integration (ISI) embedded in ERP supported the enabling approach to management control, and whether this in turn would result into higher performance and perceived system succ…
Diversité microbienne des sols : stratégie méthodologique, distribution spatiale et traduction en fonctionnement biologique
2011
International audience; Since the development of industrialization, urbanization and agriculture, soils have been subjected to numerous variations in environmental conditions, which have resulted in modifications of the taxonomic diversity and functioning of the indigenous microbial communities. As a consequence, the functional significance of these losses/modifications of biodiversity, in terms of the capacity of ecosystems to maintain the functions and services on which humanity depends, is now of pivotal importance. In this context, one of the main challenges in soil microbial ecology is to better understand and predict the processes that drive soil microbial diversity and the link betwe…
Adolescents’ preparedness and motivation across the transition to post-comprehensive education
2017
This longitudinal study aims to test the concept of transition preparedness in the context of educational transitions. The study investigates how adolescents' transition preparedness, conceptualized as their self-efficacy beliefs and their inoculation against setbacks, before an educational transition affect the adolescents' school value and effort related to educational goals after the transition through the effects on achievement goal orientations. Student data from three waves of a longitudinal study are used, first collected in 2004 (before the students' transition from comprehensive school to upper secondary education) and then collected twice after the transition. The students include…
Part-time special education predicts students' reading self-concept development
2018
Abstract The academic self-concept changes from childhood to early adulthood in relation to experiences of capability in different school tasks and comparison with peers. Students in special education have a lower academic self-concept than their peers do, but it is unclear how part-time special education affects self-concept development. In Finnish schools, part-time special education is learning support that is usually provided for 1–2 h/week in small groups. The main aim of this study was exploring the effects of participation in part-time special education and gender on the level and change in three academic self-concept domains (General School, Mathematics and Reading) between the ages…
