A photometric study of Be stars located in the seismology fields of COROT
2007
Context: In preparation for the COROT mission, an exhaustive photometric study of Be stars located in the seismology fields of the COROT mission has been performed. The very precise and long-time-spanned photometric observations gathered by the COROT satellite will give important clues of the origin of the Be phenomenon. Aims: The aim of this work is to find short-period variable Be stars located in the seismology fields of COROT and to study and characterise their pulsational properties. Methods: Light curves obtained at the Observatorio de Sierra Nevada together with data from Hipparcos and ASAS-3 of a total of 84 Be stars have been analysed in order to search for short-term variations. W…
STUDENT GRAPHICAL INFORMATION LITERACY IN MATHEMATICS AND SCIENCE
2017
Among the most important 21st century skills that every student needs are the ability to work with information. The key for implementing competency based approach to learning will be related to how students' ability to apply skills acquired in, for example, mathematics can be transferred to other subject contexts. Newest OECD PISA results presented in 2016 show a recurring tendency that in Latvia there is a small number of students whose performance is in accordance to the 5th and 6th level of the framework. These two levels represent students' ability to apply deep thinking skills in new learning contexts. It is necessary to analyze the causes of this situation in order to identify opportu…
Effects of contextual variables on strategic investment decision-making styles: An empirical study from Pakistan.
2022
There is a gap in the literature of strategic investment decision making (SIDM) concerning the links between context variables, infrastructure and SIDM practices (or SIDM styles) in developing countries. This research aims to fill that gap. Survey data (N = 128) from the manufacturing companies listed on the Pakistan Stock Exchange was collected via an e-mailed questionnaire and visits to the companies. Data are analyzed with factor analysis and multiple regression analysis. The results reveal what we call four different SIDM styles (or emphases): managerial power-, financial analysis-, top management-, and strategy-based investing. These styles are considered to be novel perspectives on SI…
Last millennium northern hemisphere summer temperatures from tree rings: Part I: The long term context
2016
Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала. Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have been progressively improved over the last 20 years as new datasets have been developed. This paper, and its companion (Part II, Anchukaitis et al. in prep), details the latest tree-ring (TR) based NH land air temperature reconstruction from a temporal and spatial perspective. This work is the first product of a consortium called N-TREND (Northern Hemisphere Tree-Ring Network Development) which brings together dendroclimatologists to identify a collective strategy for improving large-scale summer temperature reconstructions…
Comparative transcriptomics of albino and warningly‐coloured caterpillars
2021
Abstract Coloration is perhaps one of the most prominent adaptations for survival and reproduction of many taxa. Coloration is of particular importance for aposematic species, which rely on their coloring and patterning acting as a warning signal to deter predators. Most research has focused on the evolution of warning coloration by natural selection. However, little information is available for color mutants of aposematic species, particularly at the genomic level. Here, I compare the transcriptomes of albino mutant caterpillars of the aposematic wood tiger moth (Arctia plantaginis) to those of their full sibs having their distinctive orange‐black warning coloration. The results showed >29…
Work-related language learning trajectories of migrant cleaners in Finland
2017
Cleaning is often the survival employment that migrants can get in their new home country. Ideally, the workplace can be a site for integration and language learning. This article explores how two migrants working as cleaners in Finland narrate their work-related Finnish language learning trajectories. The research is designed by applying nexus analysis (Scollon & Scollon, 2004), which focuses on social action in the intersection of interaction order, participants’ life experiences, and discourses in place. The social action in focus here is investment (Darvin & Norton, 2015), which means a commitment to developing language skills to achieve one’s aspirations. The article also analy…
The Concept of Key Success Factors in Logistics and Supply Chain Management in the Context of Creating Business Competitive Advantage
2018
Firms are constantly looking for ways to create a competitive advantage. An important place among the factors affecting the way in which this advantage is gained is taken by success factors including, but not limited to, the so-called key success factors that may be related to the domains of logistics and supply chain management. The aim of the article is to identify the basic characteristics of the concept of key success factors in logistics and supply chain management. The article presents the essence and importance of success factors in the context of creating the business competitive advantage, the basic concepts of key success factors related to resource-based and market-based strategi…
Supramolecular Organocatalysis in Water Mediated by Macrocyclic Compounds
2018
In the last decades many efforts have been devoted to design supramolecular organocatalysts able to work in water as the reaction medium. The use of water as solvent provides promising benefits with respect to environmental impact. In this context, macrocyclic compounds played a role of primary importance thanks to their ease of synthesis and their molecular recognition abilities toward the reactants. The aim of this review is to give an overview of the recent advances in the field of supramolecular organocatalysis in water, focusing the attention on calixarene and cyclodextrins derivatives. Calixarenes and cyclodextrins, thanks to their hydrophobic cavities, are able to host selectively th…
Scattering of Co-Current Surface Waves on an Analogue Black Hole
2018
We report on what is to our knowledge the first scattering experiment of surface waves on an accelerating transcritical flow, which in the analogue gravity context is described by an effective spacetime with a black-hole horizon. This spacetime has been probed by an incident co-current wave, which partially scatters into an outgoing countercurrent wave on each side of the horizon. The measured scattering amplitudes are compatible with the predictions of the hydrodynamical theory, where the kinematical description in terms of the effective metric is exact.
Physics meets Bohemia Einstein in Bohemia Michael D. Gordin Princeton University Press, 2020. 360 pp.
2020
In Einstein in Bohemia, Michael Gordin seeks to illuminate the elusive significance of Einstein9s brief tenure in Prague, both for the biography of the famous physicist and for the cultural history of Bohemia. An expert in the history of modern physical sciences and of Russian, European, and American history, Gordin pulls together a wealth of information about the wider context of Einstein9s stay in Prague and of the cultural, scientific, and political history of Bohemia.
