Increased Parasite Abundance Associated with Reproductive Maturity of the Clam Anodonta piscinalis
1999
Several studies on vertebrates have demonstrated that reproductive activities may increase the parasite load, but this has not been shown in invertebrate hosts. We studied abundance of a potentially harmful gill parasite, the ergasilid copepod Paraergasilus rylovi, from the freshwater bivalve host Anodonta piscinalis in relation to reproductive maturity of the host in the field. Prevalence of this previously unstudied parasite varied from 90 to 100%, and the mean parasite abundance from 16.3 to 28.8 among 3 study populations. Abundance of P. rylovi increased with host size. In the maturating age groups (3-5 yr) the length-adjusted mean parasite abundance among mature, reproducing female cla…
Towards a cumulative tradition in e-Government Research: Going beyond the Gs and Cs
2007
Published version of a chapter published in Lecture Notes in Computer Science, 4656, 13-22. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-540-74444-3_2 The emerging research area of e-Government is gradually moving towards a level of maturity on the back of increasingly rigorous empirical research. Yet, there has been little theoretical progress and a cumulative tradition is not emerging. We argue that a principle reason for this is a lack of shared understanding about basic concepts and entities amongst scholars in the field. Specifically, the entities that form the bedrock of e-Government research, such as “Government” and “Citizen” are conceptualized at a very gen…
The B3 Maturity Model, SCIROCCO Tool and SCIROCCO Knowledge Management Hub: facilitating the capacity-building support for integrated care
2021
Introduction SCIROCCO Exchange is an EU Health Programme project that builds upon the preliminary achievements of the B3 Action Group on Integrated Care of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) that first developed the concept of an Integrated Care Maturity Model. Through the activities of the SCIROCCO project, the Model has been further refined and is supported by a validated self-assessment tool (SCIROCCO Tool). SCIROCCO is an online participatory tool that helps stakeholders to understand: 1) The context requirements of a particular good practice; 2) The level of maturity required for a care system to adopt and scale-up integrated care; 3) The acti…
Estudio piloto sobre el estrés y la resiliencia familiar en recién nacidos prematuros
2016
Resumen: Introducción: La prematuridad se acompaña de patología severa, estancias prolongadas en el hospital e incertidumbre acerca del futuro de los pacientes. Estas circunstancias suponen un estrés que puede afectar al funcionamiento de la familia. El objetivo de este trabajo ha sido estudiar los factores de riesgo y de protección del funcionamiento familiar en prematuros comparados con neonatos sanos a término. Población y métodos: Se reclutó a prematuros que cursaron el periodo neonatal con y sin patología (n = 40) a los 24 meses de edad posconcepcional y un grupo control de nacidos a término sanos (n = 31) según datos de la historia clínica. El progenitor cuidador habitual respondió al…
Pricing and hedging GDP-linked bonds in incomplete markets
2018
Abstract We model the super-replication of payoffs linked to a country’s GDP as a stochastic linear program on a discrete time and state-space scenario tree to price GDP-linked bonds. As a byproduct of the model we obtain a hedging portfolio. Using linear programming duality we compute also the risk premium. The model applies to coupon-indexed and principal-indexed bonds, and allows the analysis of bonds with different design parameters (coupon, target GDP growth rate, and maturity). We calibrate for UK and US instruments, and carry out sensitivity analysis of prices and risk premia to the risk factors and bond design parameters. We also compare coupon-indexed and principal-indexed bonds. F…
Ryt obrzezania w Gilgal (Joz 5,2-9) momentem odnowienia relacji narodu wybranego z JHWH
2020
Przymierzom biblijnym często towarzyszyły znaki, np. tęcza (Rdz 9,12–17), krew cielców (Wj 24,3–8) czy też chleb i wino (Łk 22,19–20). Zewnętrznym znakiem przymierza, jakie Bóg zawarł z Abrahamem, było obrzezanie (Rdz 17,9–14). Obrzęd ten został zaniedbany podczas czterdziestoletniej wędrówki przez pustynię. Jednak po przejściu Jordanu JHWH upomniał się o ten znak. Tak jak obrzezanie fizyczne było warunkiem wzięcia w posiadanie Ziemi Obiecanej, tak obrzezanie serca było warunkiem utrzymania tej ziemi w rękach Izraelitów oraz gwarantowało bezpieczeństwo i pomyślność. Niniejszy artykuł prezentuje szczegółową analizę perykopy Joz 5,2–9, w której jest mowa o obrzezaniu w Gilgal i o odnowieniu r…
Adolescent Brain Development and Progressive Legal Responsibility in the Latin American Context
2020
In this article, we analyze the contributions of neuroscience to the development of the adolescent brain and shed additional light on the minimum age of criminal responsibility in the context of Latin America. In neurobiology, maturity is perceived to be complex because the brain’s temporal development process is not uniform across all its regions. This has important consequences for adolescents’ behavior; in their search for the acceptance of their peers, they are more vulnerable to pressure and more sensitive to stress than adults. Their affectivity is more unstable, and they show signs of low tolerance to frustration and important emotional reactivity, with a decrease in the capacity to …
Predicting Word Maturity from Frequency and Semantic Diversity: A Computational Study
2016
Semantic word representation changes over different ages of childhood until it reaches its adult form. One method to formally model this change is the word maturity paradigm. This method uses a text sample for each age, including adult age, and transforms the samples into a semantic space by means of Latent Semantic Analysis. The representation of a word at every age is then compared with its adult representation via computational maturity indices. The present study used this paradigm to explore to the impact of word frequency and semantic diversity on maturation indices. To do this, word maturity indices were extracted from a Spanish incremental corpus and validated, using correlation scor…
Parental experience of a risky environment leads to improved offspring growth rate.
2014
Abstract Parasites (or diseases) are major selective force for the evolution of life history traits and parasite-host evolution. Mothers can show a variety of responses to parasites during pregnancy with different consequences for them or their offspring. However, whether information in the maternal environment before pregnancy can cause a change in the phenotype of the offspring is unknown. To avoid the confounding effect of pathogens and to reduce the risk of direct effect of mother's immune activation, we injected female laboratory mice with lipopolysaccharides (LPS) before mating. In order to provide a constant information on the potential infectious risk of the environment, females wer…
Low-risk isn’t no-risk: Perinatal treatments and the health of low-income newborns
2019
We investigate the effects of perinatal medical treatments on low-income newborns who are classified as low-risk. A policy rule in The Netherlands states that low-risk deliveries before week 37 should be supervised by physicians and later deliveries only by midwives with no physician present. This creates large discontinuities in the probability of receiving medical interventions only physicians are allowed to perform. Using a regression discontinuity design, we find that babies born slightly before the week-37 cutoff are significantly less likely to die than babies born slightly later. Our data suggest that physician supervision of birth reduces the likelihood of adverse events such as fet…
