A hidden species becoming visible : biogeography and ecology of Rhynchotalona latens (Cladocera, Anomopoda, Chydoridae)
2019
A long hidden chydorid (Chydoridae, Cladocera) taxon, first found as fossil specimens and recently redefined as Rhynchotalona latens (Sarmaja-Korjonen et al., Hydrobiologia 436: 165-169, 2000) is investigated for its biogeography and ecology. Late Holocene sediment sequence from Lake Sylvilampi, NE Finnish Lapland, and R. latens spatial distribution in relation to limno-climatic attributes in Finland were examined. Principal component analyses of fossil cladoceran communities showed that R. latens is mostly affiliated with Alonella excisa-Alonopsis elongata-Alonella nana species pool. Generalized linear modeling of R. latens responses to limno-climatic variation indicated that it prefers ac…
Bryophytes of Europe Traits (BET) dataset
2023
The Bryophytes of Europe Traits (BET) dataset includes values for 65 biological and ecological traits and 25 bioclimatic variables for all 1816 bryophytes included in the European Red List (Hodgetts et al. 2019). The traits are compiled from several regional trait datasets and manually complemented using Floras, species-specific literature and expert knowledge. The bioclimatic variables are calculated using the European range of each species. Details regarding the trait compilation and extraction of bioclimatic variables can be found in the corresponding data paper (Van Zuijlen et al. 2023).
Business Model Choice for Latvian Public Employment Service: What is the Best for Labour Force Competitiveness?
2015
AbstractThis study presents a comprehensive analysis of advantages and disadvantages of different business models for public employment services (hereafter - PES) aiming to determine the model most suitable for the Latvian labour markets.The study identifies strengths and weaknesses of performance monitoring systems applied by Latvian, Estonian and Danish PES, especially in the area of the implementation of active labour market policies and suggests a set of indicators which may be used for evaluation of PES influence on the performance of the labour market in light of the EU growth strategy “Europe 2020”.The study starts with a review of the theoretical and empirical literature on the impa…
Makrozoobentosa indikatorgrupas upes nēģa Lampetra fluviatilis apdzīvotajās vietās
2020
Upes nēģis Latvijā vairāk kā 50% ikgadējās iekšzemes nozvejas, tomēr tam ir piešķirts īpaši aizsargājamās ierobežoti izmantojamās sugas statuss. Jau kopš 20. gs. vidus tiek veikti upes nēģu populāciju papildinoši pasākumi – vaislinieku pārcelšana pāri migrācijas šķēršļiem un mākslīgi pavairotu kāpuru izlaišana. Pasākumi tiek veikti upēs ar jau eksistējošu populāciju tās papildināšanas nolūkos, vai upes posmos, kuru izvēle veikta pēc virspusēja ekoloģiskā novērtējuma. Lai populācijas papildināšanas pasākumi būtu efektīvāki, nepieciešams izlaišanas vietas izvēlēties pēc vairākiem rādītājiem. Makrozoobentoss bieži tiek izmantots kā bioloģiskais indikators ūdenstilpju kvalitātes novērtēšanā. Šī…
Comparison of sampling methods for semipelagic animals in two deep basins of Lake Saimaa
1996
The efficiency of different methods for sampling semipelagic animals was compared in the deep basins of Lake Paasivesi and Lake Puruvesi of the complex Lake Saimaa, Finland, during 1990–92. Certain semipelagic animals, such as Mysis relicta, amphipods and larvae of Chaoborus flavicans, are important bioindicators of water and benthic quality. However, owing to their high mobility and vertical migrations they are difficult to sample quantitatively with traditional benthic methods.
Expectations and the term premium as time varying leading indicators of US economic activity
2009
This paper investigates the growth predictive properties of the expectation-related and term premium components of the US term spread. Results suggest that although the predictive power of two components has greater predictive power compared to the simple spread, it has a time-varying nature. The expectations-related term is positive and statistically significant up to the end of the 80s becoming insignificant afterwards. The term-premium estimates are positive and significant for a brief period in the 70s, turn insignificant after the 80s, except in short intervals at the beginning of the 90s and the 2000s, when they turn negative.
Eye tracking and the translation process: reflections on the analysis and interpretation of eye-tracking data
2014
Eye tracking has become increasingly popular as a quantitative research method in translation research. This paper discusses some of the major methodological issues involved in the use of eye tracking in translation research. It focuses specifically on challenges in the analysis and interpretation of eye-tracking data as reflections of cognitive processes during translation. Four types of methodological issues are discussed in the paper. The first part discusses the preparatory steps that precede the actual recording of eye-tracking data. The second part examines critically the general assumptions linking eye movements to cognitive processing in the context of translation research. The thir…
Effect of indomethacin on the kinetics of tumour necrosis factor alpha release and tumour necrosis factor alpha gene expression by human blood monocy…
1991
Summary In this investigation we have examined the effects of indomethacin, an inhibitor of the cyclooxygenase pathway of arachidonic acid, upon the kinetics of the release of tumour necrosis factor alpha (TNF) and of the expression of TNF gene by lipopolysaccharide (LPS)-stimulated human blood monocytes (BM). Following stimulation of BM with LPS, TNF was released within 2 h, reached peak values at 8 h and declined at subsequent time-points (24 and 48 h). Indomethacin (10−5 m ) slightly stimulated the production of TNF at 2, 4, and 8 h and prevented the decline of TNF observed at 24 and 48 h. This effect was related to the persistence of TNF synthesis, as demonstrated by kinetics evaluation…
Les motivations des managers utilisant des critères non financiers : une analyse empirique
2008
We test the motives expressed by the managers to use the non-financial indicators so that the performance of the fi rm would increase. Is that really the main reason explaining the choice of the non-financial indicators ? Our study is based on a theoretical research distinguishing the Knowledge-based perspective from the Contractual one. Is that distinction relevant ? Within this framework, is it possible to discriminate firms types according to their use of the nonfinancial indicators ?
Luminous lip-prints as criminal evidence.
2005
Luminescence is specially a useful property for the search of invisible evidences at the scene of a crime. In the latent fingerprints particular case, there are at one's disposal fluorescent reagents for their localization. The study of latent lip prints (that is lip prints from protective lipstick, or permanent or long-lasting lipstick that do not leave any visible marks) is more recent than fingerprints study. Because of the different composition of both types of prints, different reagents have been tried out on their developing. Although, lysochromes are particularly useful reagents to obtain latent lip prints, it may occur on coloured or multicoloured surfaces, the developing is not per…
