Data from: Low fitness at low latitudes: wintering in the tropics increases migratory delays and mortality rates in an Arctic breeding shorebird

2020

1. Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. 2. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration for High Arctic breeding sanderling Calidris alba using six and eight winter destinations between 55° N and 25° S, respectively. 3. Annual apparent survival was considerably lower for adult birds wintering in tropical West-Africa (Mauritania: 0.74 and Ghana: 0.75) than in three European sites (0.84, 0.84 and 0.87) and in subtropical Namibia (0.85). Moreover, compared with adults, second calendar-year sanderlings in the tropics, but not in …

The adaptations to tube-dwelling life of Propsilocerus akamusi (Diptera: Chironomidae) larvae and its eutrophication-tolerant mechanisms

2019

Propsilocerus akamusi (Diptera: Chironomidae) is a dominant macroinvertebrate species in many eutrophic lakes in subtropical and temperate zones. P. akamusi larvae can migrate deep into the sediment (>30 cm) during summer where is no oxygen. However, to our knowledge, the specific adaptive tactics of its tube-dwelling life (>30 cm) and underlying mechanisms why this species is favored by nutrient-rich lakes remain limited. With the understanding above-mentioned issues, we can provide important information for the development of sensitive biomonitoring. We examined monthly morphological dynamics and physiological adaptations of P. akamusi to anoxic conditions, and environmental relationships…

Hétérogénéité spatiale : principes et méthodes

2004

Spatial Heterogeneity : Principles and Methods This article has a dual purpose . First , it describes the main econometric specifications which can be used to represent spatial heterogeneity , reflected in an instability of parameters in space and / or a heteroscedasticity of error terms . Only the specifications valid in cross-section are examined . Second , it explains the links between spatial heterogeneity and autocorrelation , the other major feature of localised data , defined by the absence of independence between geographical observations . In particular , we look at the extent to which traditional tests of heteroscedasticity or instability need to be amended to take account of spat…

Understanding the impact of digital on performing arts: a systematic literature review proposal

2023

Digital technologies have profoundly changed the cultural and creative industries. Due to the intrinsic characteristics of the performing arts sector, this digital transition has had a later impact on it. However, it has accelerated since the Covid-19 pandemic, forcing organizations to digitally transform themselves to keep in touch with their audience(s). Now that this crisis is over, many strategic and operational questions still remain unanswered. This research proposes a systematic literature review in order to establish the state of the art of the research on digitalization of the performing arts sector and to highlight the main research avenues to be explored.

Sponsoru ietekme uz mērķauditorijas attieksmi pret atbalstītajām sporta komandām un sportistiem

2017

Bakalaura darba tēma ir “Sponsoru ietekme uz mērķauditorijas attieksmi pret atbalstītajām sporta komandām un sportistiem.” Kā galvenais darba mērķis ir noskaidrot to vai tas, ka kādas sporta komandas galvenais sponsors ir kāds uzņēmums no ātro kredītu vai azartspēļu sfēras, kādā veidā negatīvi ietekmē komandas tēlu vai attieksmi tās auditorijā. Darba problēma bija noteikt vai un kā sponsori tiek identificēti ar sponsorētajām sporta komandām to auditorijā. Darba teorētiskajā daļā tika apskatīts sporta mārketings, sponsorēšana sportā, sporta patērētāju rīcība un ētika. Metodoloģijā tika aprakstītas, un pētījuma daļā pielietotas, kvalitatīvas pētniecības metodes – kvalitatīvā aptauja, anketēša…

Les animaux de la nécropole gallo-romaine de Vertault (Côte d'Or, France)

2007

The skeletons, partial skeletons and isolated bones of 200 dogs, 42 horses, eight sheep and two cattle were recovered at the animal necropolis of Vertault, situated south of the fortifi ed rampart belonging to the Gaulish-Roman village on an incompletely examined stretch of land. Because archaeological fi nds were lacking, three 14C analyses were conducted on horse bone material to provide chronological identifi cation, which dated the faunal remains to the 1st century AD. All of the animals are males. Although the horses are fully mature and some of them very old, the dogs and sheep are all young animals. These animals, some of which show clear evidence on the skull of violent death, were …

Percutaneous Recanalization of Chronic Total Occlusions : 2019 Consensus Document from the EuroCTO Club

2019

Since its inception in December 2006, the EuroCTO Club has strived to provide the framework for state-of-the-art chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in Europe and nearby regions. Among its initiatives, the EuroCTO Club has published a set of recommendations regarding the technical aspects of CTO PCI, whose last edition dates to 2012. The EuroCTO Club consensus document discusses CTO PCI clinical indications, techniques and equipment use, as well as the qualifications of operators/centres. Given the considerable amount of progress made by this subspecialty in recent years, there is a need for an updated document that includes data from recent clinical trial…

Radiation Exposure for Percutaneous Interventions of Chronic Total Coronary Occlusions in a Multicenter Registry: The Influence of Operator Variabili…

2021

Aims. Radiation exposure is a limiting factor for percutaneous coronary interventions (PCI) of chronic total coronary occlusion (CTO) lesions. This study was designed to analyze changes in patient radiation dose for CTO-PCI and parameters associated with radiation dose. Methods and Results. We analyzed a cohort of 12,136 procedures performed by 23 operators between 2012 and 2017 from the European Registry of CTO-PCI. Radiation exposure was recorded as air kerma (AK) and dose area product (DAP). A dose rate index (DRI) was calculated as AK per fluoroscopy time to normalize for individual differences in fluoroscopy time. The lesion complexity increased from Japanese-CTO (J-CTO) score of 2.19 …

Diaspora Start-Up Programs and Creative Industries: Evidence from Romania

2021

Romania is one of the main countries of origin for intra-European migration. The national authorities recently implemented the first major program —Diaspora Start-up—to support the business initiatives of Romanian citizens who live abroad and who are interested in opening a business in their home country. This scheme was developed in parallel with a broader program—Romania Start-up Plus—which was designed to support the entrepreneurial initiatives of individuals residing inside the country. These programs have already supported over 8,600 non-agricultural start-ups created in urban areas. This study conducted a comparative analysis of the two programs based on different criteria and explore…
