The sensorimotor and cognitive integration of gravity.
1998
In order to demonstrate that gravity is not only a load acting locally and continuously on the body limbs, but is also used by higher levels of the nervous system as a dynamic orienting reference for the elaboration of the motor act, a review of several experiments conducted both in 1 g and 0 g are presented. During various locomotor tasks, the strategy that consists of stabilizing the head with respect to gravity illustrates one of the solutions used by the CNS to optimize the control of dynamic equilibrium. A question which remains to be solved when considering experimental results obtained in weightlessness concerns, however, the maintenance of motor schema that has evolved under normal …
Grip Force Adjustments Reflect Prediction of Dynamic Consequences in Varying Gravitoinertial Fields
2018
International audience; Humans have a remarkable ability to adjust the way they manipulate tools through a genuine regulation of grip force according to the task. However, rapid changes in the dynamical context may challenge this skill, as shown in many experimental approaches. Most experiments adopt perturbation paradigms that affect only one sensory modality. We hypothesize that very fast adaptation can occur if coherent information from multiple sensory modalities is provided to the central nervous system. Here, we test whether participants can switch between different and never experienced dynamical environments induced by centrifugation of the body. Seven participants lifted an object …
Membrane insertion and topology of the p7B movement protein of Melon Necrotic Spot Virus (MNSV)
2007
AbstractCell-to-cell movement of the Melon Necrotic Spot Virus (MNSV) is controlled by two small proteins working in trans, an RNA-binding protein (p7A) and an integral membrane protein (p7B) separated by an amber stop codon. p7B contains a single hydrophobic region. Membrane integration of this region was observed when inserted into model proteins in the presence of microsomal membranes. Furthermore, we explored the topology and targeting mechanisms of full-length p7B. Here we present evidence that p7B integrates in vitro into the ER membrane cotranslationally and with an Nt-cytoplasmic/Ct-luminal orientation. The observed topology was monitored in vivo by fusing GFP to the Ct of p7B, enab…
Is morphokinetic analysis the answer?
2013
Abstract Efforts aimed at improving pregnancy rates have focused on the search for additional markers of viability to supplement current criteria for embryo selection. Time-lapse technology represents a powerful tool in assisted reproduction for evaluating embryos dynamically. Whilst standard methods of embryo assessment are based on subjective morphology evaluation at discrete time points, thereby limiting the information produced for embryo selection, time-lapse recording introduces several additional morphokinetic parameters for embryo evaluation. This additional information can improve implantation rates and reproductive outcomes. This review surveys available knowledge on time-lapse im…
Antifeminismo y troleo de género en Twitter. Estudio de la subcultura trol a través de #STOPfeminazis
2020
espanolEn los ultimos anos, el auge del movimiento feminista, especialmente desde la convocatoria del 8M de 2018, se ha encontrado con resistencias importantes. En el ambito digital, esta renovacion del feminismo ha supuesto un aumento del activismo digital feminista y una mayor visibilidad de las mujeres. Sin embargo, tambien han surgido multiples obstaculos que muestran el caracter androcentrico y misogino de la cultura digital. Uno de los fenomenos asociado a la misoginia digital es el “troleo de genero” (gendertrolling), propio de la subcultura troll. En este trabajo, analizaremos el troleo antifeminista en la plataforma Twitter, centrandonos en la etiqueta #STOPfeminazis. A partir del …
Integrating digital documents by means of concept maps: testing an intervention program with eye-movements modelling examples
2021
When using the Internet to learn about a curricular topic students face the challenge of not only understanding each single document, but also of integrating the ideas in a combined representation. Several intervention studies have tested instructional methods, such as building concept maps, aimed at teaching integration of multiple documents to Secondary education and older students. However, building a concept map may be demanding for learners and requires competencies to build maps in an appropriate way. In the current study we explore the extent to which such integration processes relying a concept map mapping instruction can be efficiently taught to 6th grade students. Specifically, we…
OLTRE LA FAMIGLIA. PRATICHE EDUCATIVE NELLE COMUNITA' HIPPY DEGLI ANNI SETTANTA
2020
Between the Sixties and the Seventies a youth movement of protest spread in Italy, targeting the society and its most important institutions: the church and the family. Simultaneously together with the student movement, there was a counterculture phenomenon, the hippie movement, that wanted the death of the family and chose alternative and unregulated lifestyles as forms of challenge to parental authority. Many young people decided to flee from their families to go and live in the so-called “community”, where educational practices were experienced. They were educational practices that proposed an alternative model to the patriarchal and bourgeois family, whose authoritarian model of educati…
European leaders unmasked: Covid-19 communication strategy through Twitter
2020
[EN] The coronavirus disease Covid-19 (SARS-CoV-2) pandemic is exacting a huge toll on individuals, families, communities, and societies across the world. The study of public communication is a key aspect for slowing the spread of the virus and therefore reducing the death rate. This article analyses political leaders' crisis communication during the Covid-19 pandemic of the most affected European countries, Boris Johnson (United Kingdom), Emmanuel Macron (France), Pedro Sanchez (Spain) and Giuseppe Conte (Italy), in addition to Tedros Adhanom as a representative of the World Health Organisation (WHO) and Ursula Von der Leyen President of the European Union (EU). The study focuses on the vi…
Motor skills of young adults with Asperger syndrome: A comparative study
2009
Motor skill difficulties are mentioned as a common feature of Asperger syndrome (AS) but specific information regarding young adults is scarce. The purposes of this study were: to compare the motor skills of young adults with AS with age and gender matched controls using the updated version of the standardized Movement Assessment battery for children (M-ABC-II), and to compare the motor skills between younger and older participants within both groups (index and control group). Additionally validity and reliability of the M-ABC-II for use with the present population were explored. Young adults with AS performed these motor tasks at a remarkably lower level than their peers. They continued to…
Social movements and the contested institutional identity of the hospital
2020
Taking popular protest as a common reaction to changes in hospital services as its point of departure, this paper explores how a social movement has taken on the issue of the hospital as an institution. In the wake of the transformation of Norwegian public hospitals into health enterprises (trusts), this paper explores community resistance to the proposals and plans of decision-makers to restructure hospitals. The study is based on a qualitative and quantitative analysis of the website/blog for the local hospital movement's activities from 2007 until 2017 and of its involvement and resistance in respect of three instances of proposed change to the hospital structure during this period. The …
