The effect of different accentuated eccentric load levels in eccentric-concentric loading contractions on acute neuromuscular, growth hormone and blo…
2007
When accentuated load is applied during the eccentric (ECC) phase of eccentric-concentric (ECC-CON) contractions, it is defined as dynamic accentuated external resistance (DAER) exercise. This study monitored acute neuromuscular responses, growth hormone (GH) and blood lactate (La) concentrations to find out the most efficient ECC-CON loading strategy for muscle hypertrophy by employing various DAER resistances in the bench-press. Male subjects (age=32.4±4.3years, n=11) were assigned as subjects. The measurements consisted of 4 “hypertrophic” sessions separated by 5-6 days recovery. The subjects performed 4 sets of 10 repetitions with 2 min recovery between the sets. The resistances were 70…
Morphological similarities between DBM and a microeconomic model of sprawl
2010
JEL classification : C61; C63; D62; R21; R40; International audience; We present a model that simulates the growth of a metropolitan area on a 2D lattice. The model is dynamic and based on microeconomics. Households show preferences for nearby open spaces and neighbourhood density. They compete on the land market. They travel along a road network to access the CBD. A planner ensures the connectedness and maintenance of the road network. The spatial pattern of houses, green spaces and road network self-organises, emerging from agents individualistic decisions. We perform several simulations and vary residential preferences. Our results show morphologies and transition phases that are similar…
Self-perceptions of competence in Brazilian, Canadian, Chinese and Italian children: Relations with social and school adjustment
2004
The purpose of the present study was to examine relations between self-perceptions of competence and social, behavioural, and school adjustment in Brazilian, Canadian, Chinese, and Italian children. Self-perception data were collected through children’s self-reports. Information about social behaviours, peer acceptance, and school achievement was obtained from peer assessments and teacher ratings. Multi-group analyses revealed similar patterns of relations between self-perceptions in scholastic and general self-worth domains and social and school performance in the four samples. However, the relations between self-perceptions of social competence and shyness and academic achievement were d…
Event-based encoding from digital magnetic compass and ultrasonic distance sensor for navigation in mobile systems
2016
Event-based encoding reduces the amount of generated data while keeping relevant information in the measured magnitude. While this encoding is mostly associated with spiking neuromorphic systems, it can be used in a broad spectrum of tasks. The extension of event-based data representation to other sensors would provide advantages related to bandwidth reduction, lower computing requirements, increased processing speed and data processing. This work describes two event-based encoding procedures (magnitude-event and rate-event) for two sensors widely used in industry, especially for navigation in mobile systems: digital magnetic compass and ultrasonic distance sensor. Encoded data meet Address…
Geo‐referencing naturalistic driving data using a novel method based on vehicle speed
2013
Naturalistic driving is an experimentation model that allows us to recognise the driving modes observing the driver's behaviour at the wheel of a set of people in natural conditions during long periods of observation. This research methodology aims at increasing the representativeness of the data collected in opposition to data stemming from highly controlled laboratory experiments. However, naturalistic driving research designs produce large volumes of data that are difficult to handle. Thus, it is very important to work with suitable methods for representing and interpreting data, allowing us to observe the variability of the results. The aim of this study is to implement a new methodolog…
Repatriation of Debt in the Euro Crisis: Evidence for the Secondary Market Theory
2013
The Euro Crisis has marked a sharp inversion in the process of the European financial integration and, more specifically, a repatriation of countries' debt from foreign to domestic investors. Yet the drivers of the financial fragmentation remain unclear. This paper investigates the empirical patterns in light of competing theories of cross-border portfolio allocation. Three main empirical regularities stand out: i) the repatriation of debt occurred primarily in crisis countries; ii) the repatriation affected mainly public debt; iii) the public debt of crisis countries was reallocated to politically influential countries within the Euro Area. Standard theories of portfolio allocation and hom…
Public debt, money and consumer prices: a vector error correction model for Germany
2015
In the paper, the authors analyse the interaction between public debt and inflation including the mutual impulse response. The European sovereign debt crisis brought once again a focus onto the consequences of government debt in combination with an expansionary monetary policy for the development of consumer prices. Public deficits can lead to higher inflation rates if the money supply is expansionary. The high level of national debt, not only in the Euro-crisis countries, and the strong increase in the total assets of the European Central Bank, as a result of the unconventional monetary policy, have caused fears of inflating government debt. The transmission from public debt to inflation t…
Determining the Set of Concept Map Based Tasks for Computerized Knowledge Self-Assessment
2012
Demands for educated labor force with well-integrated cognitive structures call for necessity to use in educational institutions appropriate teaching and knowledge assessment methods directed towards fine development and assessment of students’ conceptual understanding. Concept maps as a kind of mental models have great potential in knowledge assessment due to several significant advantages. However, a taxonomy of possible concept mapping tasks has not been developed yet. The paper considers the problem of extending a set of concept mapping tasks in the already developed concept map based knowledge assessment system. The possible types of tasks are investigated from the point of view of the…
Análisis de la sostenibilidad del sector exterior en la OCDE con técnicas de multicointegración
2022
Este artículo analiza la sostenibilidad externa de un grupo de 23 países de la OCDE durante el periodo 1970-2020. La estrategia empírica adoptada muestra la importancia del desequilibrio acumulado como desencadenante del ajuste externo, en línea con la propuesta de Gourinchas y Rey (2007). Para ello, contrastamos la sostenibilidad externa a través de la relación acumulado-flujo entre las variables que representan las relaciones externas de una economía abierta utilizando varios tipos de contrastes de cointegración y multicointegración. Los resultados obtenidos apuntan hacia la sostenibilidad en sentido débil en el análisis de los flujos, mientras que desde el punto de vista del enfoque acum…
Institutional Dynamics in International Organizations: Lessons from the Recruitment Procedures of the European External Action Service
2014
Author's version of an article in the journal: Organization Studies. Also available from the publisher at: http://dx.doi.org/10.1177/0170840614544558 This article examines how organizational designs develop by proposing a novel theoretical framework that views organizational change as resulting from a dialectic process between interpretive agents. The key claim is that existing formal procedures (such as recruitment processes, our empirical focal point) are subject to involved actors’ interpretive efforts. This results in a bargaining situation based on the interpretations of the principal actors, which may induce a feedback loop whereby the original procedures are amended. The empirical re…
