The Delimitation and Coherence of Functional and Administrative Regions

The aim of this paper is to examine the coherence between and within functional as well as administrative regions in a labour market context. The larger the coherence of the local labour markets within the delimited regions, the larger the heterogeneity between the delimited regions is expected to be for particular measures related to the economy and the labour market. Contrary to previous delimitation studies we test for labour market coherence. The functionally defined regions are compared with the administratively defined regions with respect to four economic indicators: (i) income level; (ii) housing prices; (iii) employment rate, and (iv) unemployment rate. It turns out that the administrative delimitation of the Netherlands performs, on average, equally well as the functional delimitation. The hypothesis that the municipalities within the administratively defined regions show less coherence than the municipalities within the functionally delimited regions, cannot be rejected. We find some minor evidence that the coherence is greater for the average income level of municipalities within functional regions than within administrative regions. It can be concluded that there is not much to be gained in labour market policies by using functional instead of administrative divisions of regional labour markets. Therefore we doubt the usefulness of other studies on functional delimitations of labour market regions. Finally, our results imply that it may be better for regional labour market policies not to use a highly differentiated division of regions for such a small country as the Netherlands.education, training and the labour market;

Navigating the Currents of Seascape Genomics: How Spatial Analyses can Augment Population Genomic Studies

Population genomic approaches are making rapid inroads in the study of non-model organisms, including marine taxa. To date, these marine studies have predominantly focused on rudimentary metrics describing the spatial and environmental context of their study region (e.g., geographical distance, average sea surface temperature, average salinity). We contend that a more nuanced and considered approach to quantifying seascape dynamics and patterns can strengthen population genomic investigations and help identify spatial, temporal, and environmental factors associated with differing selective regimes or demographic histories. Nevertheless, approaches for quantifying marine landscapes are complicated. Characteristic features of the marine environment, including pelagic living in flowing water (experienced by most marine taxa at some point in their life cycle), require a well-designed spatial-temporal sampling strategy and analysis. Many genetic summary statistics used to describe populations may be inappropriate for marine species with large population sizes, large species ranges, stochastic recruitment, and asymmetrical gene flow. Finally, statistical approaches for testing associations between seascapes and population genomic patterns are still maturing with no single approach able to capture all relevant considerations. None of these issues are completely unique to marine systems and therefore similar issues and solutions will be shared for many organisms regardless of habitat. Here, we outline goals and spatial approaches for landscape genomics with an emphasis onmarine systems and review the growing empirical literature on seascape genomics. We review established tools and approaches and highlight promising new strategies to overcome select issues including a strategy to spatially optimize sampling. Despite the many challenges, we argue that marine systems may be especially well suited for identifying candidate genomic regions under environmentally mediated selection and that seascape genomic approaches are especially useful for identifying robust locus-by-environment associations

Liquidity risk premia : an empirical analysis of european corporate bond yields

In this study we highlight the importance of liquidity risk, especially in periods of market stress, and advocate in favour of an explicit consideration of a liquidity premium when using mark-to-model methodologies to value financial assets. For European corporate bonds, we show that the liquidity premium, calculated as the difference between the yield spread of corporate bonds and the spread of credit default swaps, grew significantly during the recent market turmoil not only in absolute terms but also in relative terms. Although liquidity premiums were far from stable during the time frame of analysis-from 1 January 2005 to 31 December 2009 - on average roughly 40% of corporate yield spreads can be interpreted in terms of liquidity premia. We propose direct matching between the CDS and the underlying reference assets when computing liquidity premia. This differs from what seems to be the industry standard, which is simply to use indices when trying to infer market implied liquidity premia. Although computationally more demanding, the method we use is sounder from a theoretical point of view and produces richer results and analysis. With this method we are able present an analysis of liquidity risk premia per sector of activity

Incidence of urinary retention during treatment with single tablet combinations of solifenacin+tamsulosin OCAS™ for up to 1 year in adult men with both storage and voiding LUTS: a subanalysis of the NEPTUNE/NEPTUNE II randomized controlled studies

Introduction: The emergence of urinary retention (UR), specifically acute urinary retention (AUR), has been a concern when treating men with lower urinary tract symptoms (LUTS) with antimuscarinic drugs. Materials and methods: In NEPTUNE (12-week, double-blind), men (≥45 years) with LUTS were randomized to receive tamsulosin oral-controlled absorption system (TOCAS) 0.4 mg, fixed-dose combination (FDC) of solifenacin (Soli) 6 mg + TOCAS 0.4 mg, FDC Soli 9 mg + TOCAS 0.4 mg, or placebo. In NEPTUNE II (40-week, open-label extension of NEPTUNE), continuing patients received 4-week FDC Soli 6 mg + TOCAS, then FDC Soli 6 mg or 9 mg + TOCAS for the remainder of the study, switchable every 3 months. Results: Across both studies, 1208 men received ≥1 dose of FDC Soli 6 mg or 9 mg + TOCAS for up to 52 weeks; 1199 men completed NEPTUNE and 1066 received ≥1 dose in NEPTUNE II. In total, 13 men (1.1%; 95% CI, 0.6%-1.8%) reported a UR event while receiving FDC, eight of which were AUR (0.7%; 95% CI, 0.3%-1.3%, incidence 7/1000 man-years). Six men reported UR events while taking Soli 6 mg + TOCAS (three AUR), and seven men reported a UR event while taking Soli 9 mg + TOCAS (five AUR). One man developed AUR while taking TOCAS alone and four reported UR (three AUR) during placebo run-in. Most AUR/ UR events occurred within 4 months of treatment initiation. Conclusions: FDC Soli and TOCAS was associated with a low rate of UR and AUR in men with LUTS

Native Speaker Perceptions of Accented Speech: The English Pronunciation of Macedonian EFL Learners

The paper reports on the results of a study that aimed to describe the vocalic and consonantal features of the English pronunciation of Macedonian EFL learners as perceived by native speakers of English and to find out whether native speakers who speak different standard variants of English perceive the same segments as non-native. A specially designed computer web application was employed to gather two types of data: a) quantitative (frequency of segment variables and global foreign accent ratings on a 5-point scale), and b) qualitative (open-ended questions). The result analysis points out to three most frequent markers of foreign accent in the English speech of Macedonian EFL learners: final obstruent devoicing, vowel shortening and substitution of English dental fricatives with Macedonian dental plosives. It also reflects additional phonetic aspects poorly explained in the available reference literature such as allophonic distributional differences between the two languages and intonational mismatch

CE-MS metabolic profiling of volume-restricted plasma samples from an acute mouse model for epileptic seizures to discover potentially involved metabolomic features

Currently, a high variety of analytical techniques to perform metabolomics is available. One of these techniques is capillary electrophoresis coupled to mass spectrometry (CE-MS), which has emerged as a rather strong analytical technique for profiling polar and charged compounds. This work aims to discover with CE-MS potential metabolic consequences of evoked seizures in plasma by using a 6Hz acute corneal seizure mouse model. CE-MS is an appealing technique because of its capability to handle very small sample volumes, such as the 10 mu L plasma samples obtained using capillary microsampling in this study. After liquid-liquid extraction, the samples were analyzed with CE-MS using low-pH separation conditions, followed by data analysis and biomarker identification. Both electrically induced seizures showed decreased values of methionine, lysine, glycine, phenylalanine, citrulline, 3-methyladenine and histidine in mice plasma. However, a second provoked seizure, 13 days later, showed a less pronounced decrease of the mean concentrations of these plasma metabolites, demonstrated by higher fold change ratios. Other obtained markers that can be related to seizure activities based on literature data, are isoleucine, serine, proline, tryptophan, alanine, arginine, valine and asparagine. Most amino acids showed relatively stable plasma concentrations between the basal levels (Time point 1) and after the 13-day wash-out period (Time point 3), which suggests its effectiveness. Overall, this work clearly demonstrated the possibility of profiling metabolite consequences related to seizure activities of an intrinsically low amount of body fluid using CE-MS. It would be useful to investigate and validate, in the future, the known and unknown metabolites in different animal models as well as in humans.Analytical BioScience

Deep reefs of the Great Barrier Reef offer limited thermal refuge during mass coral bleaching

Our rapidly warming climate is threatening coral reefs as thermal anomalies trigger mass coral bleaching events. Deep (or "mesophotic") coral reefs are hypothesised to act as major ecological refuges from mass bleaching, but empirical assessments are limited. We evaluated the potential of mesophotic reefs within the Great Barrier Reef (GBR) and adjacent Coral Sea to act as thermal refuges by characterising long-term temperature conditions and assessing impacts during the 2016 mass bleaching event. We found that summer upwelling initially provided thermal relief at upper mesophotic depths (40 m), but then subsided resulting in anomalously warm temperatures even at depth. Bleaching impacts on the deep reefs were severe (40% bleached and 6% dead colonies at 40 m) but significantly lower than at shallower depths (60-69% bleached and 8-12% dead at 5-25 m). While we confirm that deep reefs can offer refuge from thermal stress, we highlight important caveats in terms of the transient nature of the protection and their limited ability to provide broad ecological refuge.XL Catlin Seaview Survey; Waitt Foundation; XL Catlin Group; Underwater Earth; University of Queensland; ARC Discovery Early Career Researcher Award (DECRA) [DE160101433]; Portuguese Science and Technology Foundation (FCT) [SFRH/BPD/110285/2015]; Australian Research Council (ARC
