Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII
2019
Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…
‘Haz lo que puedas’. Un estudio de caso sobre diversidad funcional y Educación Física
2019
Resumen basado en el de la publicación Título, resumen y palabras clave disponibles en español y en inglés Las experiencias de las personas con diversidad funcional en Educación Física (EF) suelen ser poco satisfactorias. Por ello, se pretende estudiar las experiencias de Félix, un hombre con miopatía congénita y usuario de silla de ruedas. Félix fue escogido para el estudio a propósito, debido a su historial educativo vinculado a las ciencias del deporte y la enseñanza de la EF. Se llevaron a cabo cuatro entrevistas en profundidad. En estas, se repasaron las etapas de Primaria y Secundaria, la Licenciatura en Ciencias de la Actividad Física y el Deporte y el posterior paso de Félix por el …
Spatial Ability and Learning to Program
2008
Results in introductory computer programming modules are often disappointing, and various individual differences have been found to be relevant. This paper reviews work in this area, with particular reference to the effect of a student’s spatial ability. Data is presented on a cohort of 49 students enrolled on an MSc in Information Technology course at a university in the UK. A measure was taken of their mental rotation ability, and a questionnaire administered that focused on their previous academic experience, and expectations relating to the introductory computer programming module they were studying. The results showed a positive correlation between mental rotation ability and success i…
The development of school and sports task values among adolescent athletes : The role of gender
2022
AbstractSuccessfully integrating elite sports with education requires motivation to commit oneself to both domains. This study examines the development of and gender differences in adolescent athletes’ task values for school and sports across the upper secondary school years. A total of 391 adolescents (aged 15–16 at the beginning of the study) were followed four times during sports upper secondary school. The participating student athletes were recruited from six sports upper secondary schools in Finland, which offer equal competitive sport opportunities for both genders. The results showed that school- and sports- task values are strongly related to each other. Males valued school less th…
Individual consistency and sex differences in migration strategies of Scopoli’s shearwaters Calonectris diomedea despite year differences
2014
Abstract Recently-developed capabilities for tracking the movements of individual birds over the course of a year or longer has provided increasing evidence for consistent individual differences in migration schedules and destinations. This raises questions about the relative importance of individual consistency versus flexibility in the evolution of migration strategies, and has implications for the ability of populations to respond to climatic change. Using geolocators, we tracked the migrations of Scopoli’s shearwaters Calonectris diomedea breeding in Linosa (Italy) across three years, and analysed timing and spatial aspects of their movements. Birds showed remarkable variation in their …
Abnormal Lipopigments and Lysosomal Residual Bodies in Metachromatic Leukodystrophy
1990
Ultrastructurally, metachromatic leukodystrophy (MLD) is marked by characteristic features such as herringbone, prismatic and tufaceous patterns which are typically encountered within oligodendrocytes of the central nervous system (CNS) and in Schwann cells (PNS). These patterns can be documented in late infantile, juvenile, and adult forms. In the latter, aging of the ailing individual adds another component, the accumulation of lipopigments which are marked by an opaque supposedly lipid droplet and a granular component. While MLD-specific lysosomal residual bodies occur in myelinforming cells, lipopigments accrue in neurons and to a lesser degree in astrocytes. MLD represents a unique exa…
Providing insights into browntail moth local outbreaks by combining life table data and semi-parametric statistics
2011
1. Life table studies have been an essential tool for the comprehension of insect population dynamics, although their use has been methodologically biased by a primary focus on mortality factors, especially natural enemies. Thus, studies in natural populations may relegate important mortality sources to the ‘unknown’ or ‘residual’ mortality categories. To overcome this limitation, life tables may be complemented by combining them with other approaches. 2. The aim of the present study was to provide insights into browntail moth Euproctis chrysorrhoea L. (Lepidoptera: Lymantriidae) local outbreaks by combining life table data and statistical modelling. First, E. chrysorrhoea population densit…
Population-level consequences of risky dispersal
2014
Achieving sufficient connectivity between populations is essential for persistence, but costs of dispersal may select against individual traits or behaviours that, if present, would improve connectivity. Existing dispersal models tend to ignore the multitude of risks to individuals: while many assess the effect of mortality costs, there is also a risk of failing to find new habitat, especially when the entire inhabitable area remains both small and fragmented. There are few known rules governing whether individuals evolve to disperse more, or less, than what is ideal for population connectivity and persistence. Here we aim to fill this gap, while also noting that evolution might not only pr…
The Health Competency Determinant Factors of Latvian Population
2013
Competencies develop and changes throughout a person’s life, they can gain or lose, going through various age stages. Their development does not end in youth, but continue on through the adult life. The ability to thing and reflect those thoughts specifically come forward in the center of structure of competency, which grows at the same time as the individual matures. One of the competency types is health competency. Health competency is a relatively new concept; it is not sufficiently researched. Aim of the study was to determine the factors of an adult individual health competency. 827 respondents participated in the study, in the processing of data was used SPSS. Was used factor analysis…
A new approach to the Late Miocene-Early Pliocene forms of the genus Apocricetus. Apocricetus alberti (Rodentia, Mammalia) from Venta del Moro (Cabri…
2014
Abstract The species of the genus Apocricetus are considered to form the phyletic lineage A. aff. plinii (MN11)– A. plinii – A. alberti – A. barrierei – A. angustidens (MN16). Along this lineage, gradual morphological and biometrical changes occur, but not all the species are represented by rich populations. The assemblage of Apocricetus alberti from Venta del Moro is by far the most abundant collection of this species. This population shows a great morphological variability in some characters like the morphology of the anteroconid and the anterolophulids in m1 and the shape of the anterolophule in M1, with morphotypes that resemble both older and younger populations of Apocricetus . Along …
