A Reconsideration of the Role of Forward-Market Arbitrage in Keynes’s and Hicks’s Theories of the Term Structure of Interest Rates
2014
International audience; This paper develops the relationship between Hicks’s and Keynes’s writings on the theory of the term structure of interest rates, and shows in detail how Hicks built on and extended Keynes’s account. According to this theory, the level of the long-term interest rate is determined by expectations of future short-term rates. Keynes’s thinking contained several notions – such as the preferred habitat of lenders, the theory of forward markets, and risk-premiums – which Hicks used to give a more complete theory of the term structure of interest rates. Besides implementing these notions in his own theory, Hicks introduced the concepts of the preferred habitat of borrowers,…
Evidence suggests an opportunistic entomophagous diet of the White Stork Ciconia ciconia in Sicily during breeding and post-breeding periods
2022
Insects are known to represent a critical part of the White Stork Ciconia ciconia diet throughout its breeding range. Yet, the composition of the diet in the storks breeding in the Mediterranean regions remains poorly explored. Here, we investigated the diet of a population of white storks from Sicily through pellets collected in 2003, 2007, and 2020. A total of 1,928 prey items were identified and classified into six categories. Insects dominated the diet in all years and represented 99.06% of the whole prey number. Two orders of insects were mainly consumed, namely Orthoptera, which were the most frequent prey, followed by Coleoptera. Within these, carabid beetles were dominant, followed …

Road verges provide alternative habitats for some, but not all, meadow plants
2021
Questions Agricultural intensification has led to the decline of biodiverse meadows and other semi-natural grasslands. Road verges offer potential alternative habitats for meadow species, but they may not be suitable for all meadow species due to different soil properties, frequent disturbances, pollution or suboptimal management. Are the communities of vascular plants and bryophytes similar or dissimilar to those in mown or grazed meadows? What kind of species are associated with road verges, mown meadows or grazed meadows? How do the habitat types differ in their soil conditions and disturbance intensity? Location The study was conducted on 36 sites in Central Finland. Methods We compared…
Can specific pre-workout meals reduce bone resorption in young gymnasts?
2021
The pre-adolescence in woman is a key stage to obtain adequate bone mineral content and to decrease the risk of osteoporosis in adulthood. Exercise and adequate nutrition can influence the bone growth process. The aim of this paper was to verify if a different pre-exercise meal can change exercise-induced bone resorption in female child artistic gymnasts. Twenty-eight preadolescent female were requited for this study. Training was preceded by high-carbohydrate meal (HCM; 300 kcal, 88% carbohydrates, 9% protein, 3% fat) or high protein meal (HPM; 300 kcal, 55% carbohydrates, 31% protein, 13% fat) ninety minutes before the start of the training session. Bone resorption biomarker, C-terminal t…
Connectedness and connectivity of the Natura 2000 network of protected areas across country borders in the European Union
2012
Abstract We studied the spatial connectedness of Natura 2000 site boundaries and the functional connectivity of the Natura 2000 network across the 34 terrestrial borders of the European Union. Connectivity was measured by the dispersal success of 192 reptile, amphibian, invertebrate and plant species from Annex II of the European Union Habitats Directive, based on the presence of same species on both sides of the borders. Connectedness and connectivity varied greatly between state borders, with good and bad examples found in all parts of the European Union. Connectedness and connectivity were positively correlated. However, a few outlying examples showed that good connectedness is not neces…
Autonomic, hormonal, and subjective responses to a modified version of the TSST: a pilot study
2021
El objetivo de esta investigación fue estudiar las respuestas hormonales, autonómicas y afectivas a una versión modificada del estresor TSST en una muestra de jóvenes universitarios compuesta de treinta y ocho sujetos (11 hombres y veintisiete mujeres, 11 en la fase lútea del ciclo menstrual, 16 mujeres en la fase folicular). La respuesta hormonal se evaluó con niveles de cortisol. La frecuencia cardíaca y la actividad electrodérmica se registraron durante toda la sesión experimental y la ansiedad rasgo y estado se evaluaron antes y después de la tarea. La fase de discurso provocó la frecuencia cardíaca más alta, la mayor frecuencia de respuestas inespecíficas y el mayor nivel de conductanc…
No room for males in caves : Female‐biased sex ratio in subterranean amphipods of the genus Niphargus
2021
Sex allocation theory predicts that the proportion of daughters to sons will evolve in response to ecological conditions that determine the costs and benefits of producing each sex. All else being equal, the adult sex ratio (ASR) should also vary with ecological conditions. Many studies of subterranean species reported female-biased ASR, but no systematic study has yet been conducted. We test the hypothesis that the ASR becomes more female-biased with increased isolation from the surface. We compiled a dataset of ASRs of 35 species in the subterranean amphipod Niphargus, each living in one of three distinct habitats (surface-subterranean boundary, cave streams, phreatic lakes) representing …
Phylogeny, epidemiology and microhabitat preferences of lungworms (Pseudaliidae) in cetaceans from teh Western Mediterranean
2023
A pesar de tener una cierta reputación negativa, los parásitos pueden ofrecer una información importante sobre sus hospedadores, habiendo sido reconocidos como herramientas valiosas en varios estudios que investigan el comportamiento (Balbuena y Raga 1991), la salud (Aznar et al. 2005; Gkafas et al. 2020), la dieta (Dailey y Otto 1982), la migración (Ten et al. 2022), la estructura social (Balbuena et al. 1995) o la discriminación de stocks de cetáceos (Aznar et al. 1995). Los helmintos que parasitan a los cetáceos se pueden separar en cuatro grupos distintos: acantocéfalos (20 spp.), cestodos (38 spp.), digeneos (54 spp.) y nematodos (62 spp.). De éstos, los nematodos son los más diversos …
Lasīšanas paradumu maiņa tradicionālā un elektroniskā vidē
2019
Maģistra darba temats ir “Lasīšanas paradumu maiņa tradicionālā un elektroniskā vidē”. Mūsdienu studentiem ir būtiski saprast, kāda ir piemērotākā lasīšanas vide, jo studiju mērķiem tiem nākas lasīt gan tradicionālā, gan elektroniskā vidē, kas var sagādāt izaicinājumus, ja lasītājs ir tradicionālā piekritējs vai otrādi. Pētījuma mērķis ir noskaidrot, kādi ir studentu lasīšanas paradumi, kāda ir lasīšanas paradumu maiņa, kas saprotama kā lasīšanas paradumu izmaiņas un atšķirības, lasot elektroniskā un tradicionālā vidē un kādas lasīšanas stratēģijas tiek pielietotas lasīšanas procesā. Datu ieguvei pielietota dienasgrāmatas un intervijas pētniecības metode. Iegūtie rezultāti liecina, ka lasīš…
