No full textChanges in the structure of employment in the Polish economy between 1997-2002
No full textIn the article the author presents his considerations on the subject of changes that took place in the structure
of employment in the Polish economy in the years 1997-2002. In the first part the author writes about the
theories of A.G.B. Fischer, C. Clark and J. Fourastie, the recognized economists considered to be the initiators
of the research into structural changes on the basis of the division of the economy into three sectors. Further
on in the article, the author presents the existing trends concerning the changes among persons working in the
economic sectors of the selected countries of the Western Europe, and carries out an analysis of employment in
the three sectors of the national economy. In the final part of the article factors and conditions necessary for
structural transformations to take place in employment are discussed. Particular attention is drawn to the
observed trends and future prospects as regards changes in the employment structure in the Polish economy. The
article is concluded with the summary of observations on the subject
The Protist Ribosomal Reference database (PR2): a catalog of unicellular eukaryote Small Sub-Unit rRNA sequences with curated taxonomy
No full textThe interrogation of genetic markers in environmental
meta-barcoding studies is currently seriously
hindered by the lack of taxonomically curated reference
data sets for the targeted genes. The Protist
Ribosomal Reference database (PR2, http://ssurrna.
org/) provides a unique access to eukaryotic
small sub-unit (SSU) ribosomal RNA and DNA
sequences, with curated taxonomy. The database
mainly consists of nuclear-encoded protistan
sequences. However, metazoans, land plants,
macrosporic fungi and eukaryotic organelles (mitochondrion,
plastid and others) are also included
because they are useful for the analysis of hightroughput
sequencing data sets. Introns and
putative chimeric sequences have been also carefully
checked. Taxonomic assignation of sequences
consists of eight unique taxonomic fields. In total,136 866 sequences are nuclear encoded, 45 708
(36 501 mitochondrial and 9657 chloroplastic) are
from organelles, the remaining being putative
chimeric sequences. The website allows the users
to download sequences from the entire and partial
databases (including representative sequences
after clustering at a given level of similarity).
Different web tools also allow searches by sequence
similarity. The presence of both rRNA and rDNA
sequences, taking into account introns (crucial for
eukaryotic sequences), a normalized eight terms
ranked-taxonomy and updates of new GenBank
releases were made possible by a long-term collaboration
between experts in taxonomy and computer
scientists
Defining the determinants of endurance running performance in the heat
No full textIn cool conditions, physiologic markers accurately predict endurance performance, but it is unclear whether thermal strain and perceived thermal strain modify the strength of these relationships. This study examined the relationships between traditional determinants of endurance performance and time to complete a 5-km time trial in the heat. Seventeen club runners completed graded exercise tests (GXT) in hot (GXTHOT; 32°C, 60% RH, 27.2°C WBGT) and cool conditions (GXTCOOL; 13°C, 50% RH, 9.3°C WBGT) to determine maximal oxygen uptake (V̇O2max), running economy (RE), velocity at V̇O2max (vV̇O2max), and running speeds corresponding to the lactate threshold (LT, 2 mmol.l¡1) and lactate turnpoint (LTP, 4 mmol.l¡1). Simultaneous multiple linear regression was used to predict 5 km time, using these determinants, indicating neither GXTHOT (R2 = 0.72) nor GXTCOOL (R2 = 0.86) predicted performance in the heat as strongly has previously been reported in cool conditions. vV̇O2max was the strongest individual predictor of performance, both when assessed in GXTHOT (r = ¡0.83) and GXTCOOL (r = ¡0.90). The GXTs revealed the following correlations for individual predictors in GXTHOT;V̇O2max r =¡0.7, RE r = 0.36, LT r =¡0.77, LTP r =¡0.78 and in GXTCOOL; V̇O2max r =¡0.67, RE r = 0.62, LT r =¡0.79, LTP r =¡0.8. These data indicate (i) GXTHOT does not predict 5 km running performance in the heat as strongly as a GXTCOOL, (ii) as in cool conditions, vV̇O2max may best predict running performance in the heat. © 2018 The Author(s).

Architectural taste and patronage in Newcastle upon Tyne, 1870-1914
No full textThis thesis examines architectural taste and patronage in Newcastle upon Tyne between 1870 and 1914. During this period, the city experienced dramatic expansion as the wealth generated in industry, finance and retail was channelled into commercial and public architecture. The overall aim is to determine whether Newcastle formed a distinctive architectural culture. Newcastle's economic and social profile gave rise to specific patterns of taste and patronage. The thesis explores the cultural networks that shaped the built form of the city, arguing that architectural patronage in Newcastle was dominated by a cultural oligarchy. This group formed an architectural culture, a relatively self-contained community in which particular styles and architects were favoured above others. Newcastle was a major centre of industry, finance and retail, and played a significant role in the national economy. The thesis seeks to reposition Newcastle within the context of the dynamic forces that were reshaping Britain's built environment. As the period progressed, the distinctive patterns of taste and patronage within the city were eroded by the increasingly national economy, the influence of the metropolis and the more active role played by the centralised state. The thesis relates the architectural culture under study to the national mainstream, thus shedding light on the relationship between provincial architecture and the metropolis. The thesis employs a range of methodological strategies in order to bring the different facets of architecture into focus. With clearly defined geographical and temporal boundaries, it seeks to clarify the economic, social and cultural factors that underpin architectural production, thus offering a new insight into architectural patronage
Modelling nutritional interactions: from individuals to communities
No full textInternational audienceNutrient acquisition is a major context for ecological interactions among species but ecologists and nutritionists have developed theory in isolation from each other. Developments in agent-based modelling, state–space modelling of nutrition and multi-scale modelling of landscape ecology provide the components for a new synthesis in nutritional ecology linking the nutritional biology of individual organisms to population- and community-level processes across multiple scales within an evolutionary context. We review the core elements for such a synthesis and set out the principles for a generic modelling framework that could be used to test specific ecological hypotheses
