Data from: The oxidative cost of reproduction depends on early development oxidative stress and sex in a bird species
2016
In the early 2000’s, a new component of the cost of reproduction was proposed: oxidative stress. Since then the oxidative cost of reproduction hypothesis has, however, received mixed support. Different arguments have been provided to explain this. Among them, the lack of a life history perspective on most experimental tests was suggested. We manipulated the levels of a key intracellular antioxidant (glutathione) in captive zebra finches (Taeniopygia guttata) during a short period of early life and subsequently tested the oxidative cost of reproduction. Birds were allowed to mate freely in an outdoor aviary during several months. We repeatedly enlarged or reduced their broods to increase or …
Compte rendu de : Lakeberg, Beata Dorota (2010). Die deutsche Minderheitenpresse in Polen 1918-1939 und ihr Polen- und Judenbild . (= Die Deutschen u…
2011
Die Situation der Deutschen unter der Zweiten Republik Polens wurde schon mehrfach analysiert. In ihrer 2007 an der Universität Oldenburg vorgelegten Dissertation untersucht Beata Lakeberg die Beziehungen der Deutschen zur Mehrheit der Bevölkerung (den Polen) und zur zweitgrößten Minderheit (den Juden). Die Presse der deutschen Minderheit erweist sich dabei als geeignete Quelle, um die Meinungen der Deutschen zu veranschaulichen. Lakebergs Analyse stützt sich auf die in der Minderheitenpresse verwendeten Stereotype. Die klar dargestellte methodische Grundlage (S. 20-30) wirkt überzeugend, insbesondere der Ansatz, die Konstituierung einer einheitlichen Gruppe mit der Verwendung zweier Arten …
Strategic renewal : Can it be done profitably?
2022
Industry transformation requires strategic renewal at the level of individual firms. Executives then face the dilemma of choosing renewal paths in the face of uncertainty over the competitive environment of the future, and hence the profitability of potential strategies. This dilemma motivates us to study industry transformation from the perspective of strategic renewal among 208 large firms in the global pulp and paper industry. The findings of our qualitative comparative analysis show that only a minority of firms in our sample succeeded in profitable proactive renewal. Content-wise, there were similarities in the pursued strategies over the wider population, but only a few maintained sup…
Procedurāla 3D sfēriska reljefa ģenerēšana
2017
Datorspēļu izstrādātāji bieži sastopas ar problēmām, kad ir nepieciešama liela izmēra pasaule vai ļoti daudz dažādas pasaules. Cilvēks nevar manuāli tās izveidot un tāpēc izstrādātāji pielieto procedurālo pasauļu ģenerēšanu. Lai pasaule būtu reālistiska, tai jābūt sfēriskai. Sfēriska reljefa ģenerēšana ir netriviāla problēma, kuras risināšanai pašlaik eksistē salīdzinoši maz algoritmu, tāpēc savā darbā es aplūkoju jau eksistējošus algoritmus - plaknes un sfēriska reljefa ģenerēšanu. Uz to bāzes tika izveidots jauns algoritms, kas ir pielietojams gan plaknes, gan sfēras reljefam, un ģenerē augstas kvalitātes reljefus. Tika implementēti daži no eksistējošajiem algoritmiem un arī jauns algorit…
Detecting Kernel Vulnerabilities During the Development Phase
2015
Testing is one of the major problems in Linux kernel development cycle. Security analysis and ensuring no new vulnerabilities has been introduced is one of the toughest issues of testing. Kernel developers attempt to find as many security issues as possible before merging with the mainline branch. Failure to detect vulnerabilities will result in vulnerable kernel shipped by distribution and vulnerable systems. The kernel developers can choose between several industrial and open source tools to assist in the development process and shorten the development cycle. (Though not as many as user space developers. Kernel tools are limited and rare compared to user space tools) Some of these tools a…
Returns To Education During And After The Economic Crisis: Evidence From Latvia 2006–2012
2017
We employ EU-SILC micro data for Latvia to study how returns to education changed during the economic crisis of 2008–2009 and afterwards. We found that returns to education increased significantly during the crisis and decreased slightly during the subsequent economic recovery. The counter-cyclical effect was evident in nearly all population groups. After the crisis, education became more associated than before with a longer working week and a higher employment probability. Furthermore, we show that returns to education in Latvia are generally higher in the capital city and its suburbs than outside the capital city region, as well as for citizens of Latvia than for resident non-citizens and…
Przekonania skazanych za zabójstwo o sobie, innych i przyszłości - możliwości restrukturyzacji poznawczej jako kierunku oddziaływań resocjalizacyjnych
2014
Podstawą teoretyczną przeprowadzonych badań jest koncepcja poznawcza, która zakłada, że dla efektywnego funkcjonowania człowieka kluczowe są jego procesy poznawcze determinujące schematy przekonań na temat siebie, innych i przyszłości. Badania prezentowane w artykule przeprowadzono w grupie 232 skazanych na karę dożywotniego pozbawienia wolności lub karę 25 lat za zabójstwo. Otrzymane wyniki poddano analizie czynnikowej, która ujawniła cztery czynniki: poczucie zagubienia, przekonania o własnej zaradności, przekonania o funkcjonariuszach i przekonania o innych. W artykule zaprezentowano powiązania pomiędzy ujawnionymi zmiennymi a zmiennymi demograficzno-społecznymi w kontekście możliwości p…
Intégrer des informations en escamots dans les textes techniques : quels effets sur les processus cognitifs ?
1998
Though computerized sytems now offer a wide range of options for accessing and displaying text or text-picture information, little is known about their effects on the user's cognitive processes. In this paper, we investigate the effect of a computer-specific display (pop-up window) which consists in displaying some pieces of information in windows that appear only under user's action. Experiments were carried out to compare the pop-up window device with other devices used on paper. The experiments dealt with text only as well as text-picture documents and involved various tasks. Results are discussed from a theoretical and a practical point of view.
Optimizing management to enhance multifunctionality in a boreal forest landscape
2017
The boreal biome, representing approximately one-third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for an increased timber production with provisioning of other ecosystem services and biodiversity. However, there is still little knowledge about how forest management could help solve this challenge. Hence, studies that investigate how to manage forests to reduce trade-offs between ecosystem services and biodiversity are urgently needed to help forest owners and policy makers take informed decisions. We applied seven alternative forest management regimes using a forest growth simulator in a la…
The state-of-the-art of collaborative technologies for initial vocational education : a systematic literature review
2018

 
 
 Future workplaces require collaboration skills in which members of different work communities use technologies to solve complex problems. Vocational education and training (VET) programs need to meet the challenge to prepare students to be part of a competent workforce. Particularly initial vocational education is under pressure to develop learners’ collaboration skills and abilities. To date, however, no attempt has been made to perform a comprehensive review of the use of computer-supported collaborative learning (CSCL) technologies across different vocational education settings to account for contextual factors of VET. In this systematic review, 26 published studies …
