TECNOCRACIA DENTRO DEL ESTADO DE DERECHO: SOBRE EL RESPETO A LOS DERECHOS FUNDAMENTALES EN LAS SOCIEDADES CONTEMPORÁNEAS

2011

Aunque en la década de los 60 del siglo pasado adquiriera bastante relevancia, actualmente algunos consideran superado el debate entre democracia y tecnocracia, entre participación y experticie, al haberse alcanzado un compromiso entre ambos sistemas de toma de decisiones y de legitimación, de forma que, en lugar de oponerse, ambos sistemas se complementarían. En esta comunicación se pretende plantear la conveniencia de reabrir aquel debate, pero reformulado en la contraposición entre estado de derecho y tecnocracia. Desde este enfoque, el carácter democrático de un procedimiento en la toma de decisiones debe ser evaluado, no exclusivamente a partir de su organización, sino en función de si…

Utebarnehager – et sted for demokratisk praksis?

2013

The questions in the title is posed to discuss how an outdoor kindergarten space is contextualized and understood by those who are staying there. Nature is often seen as an especially open space, free from strong guidelines and structures. Being part of an educational practice gives the place new structures. The activities the children participate in and the employees expressed attitudes and practices are part of different discourses, which give certain limits or possibilities for what is going on at the Hut, and thus influence a democratic practice. Especially children’s play activities represent an opposition to the adult’s framing of the place. Democracy presupposes some frames, but if t…

Can radium 223 be a conservative non-surgical management of medication-related osteonecrosis of the jaw?

2019

AbstractOsteonecrosis of the jaw (ONJ) is a rare and severe necrotic bone disease reflecting a compromise in the body's osseous healing mechanisms and unique to the craniofacial region. Radium 223 dichloride (Ra223) is the only targeted alpha therapy able to extend survival in patients with bone metastases from prostate cancer. Mechanism of action and data currently available focused mainly on osteoblastic metastases from prostate cancer. In 2018, a Caucasian 54-year-old woman presented to our institution for a breast cancer with bone metastases. Since the patient refused any treatment and taking into account the bone disease, our multidisciplinary team evaluated a supplementary strategy wi…

CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know.

2020

AbstractAbdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest wit…

The relationship between trait procrastination, Internet use, and psychological functioning : results from a community sample of German adolescents

2018

Adolescents with a strong tendency for irrational task delay (i.e., high trait procrastination) may be particularly prone to use Internet applications simultaneously to other tasks (e.g., during homework) and in an insufficiently controlled fashion. Both Internet multitasking and insufficiently controlled Internet usage may thus amplify the negative mental health implications that have frequently been associated with trait procrastination. The present study explored this role of Internet multitasking and insufficiently controlled Internet use for the relationship between trait procrastination and impaired psychological functioning in a community sample of N = 818 early and middle adolescent…

Comparative ultrastructure and carbohydrate composition of gastroliths from Astacidae, Cambaridae and Parastacidae freshwater crayfish (Crustacea, De…

2012

21 pages; International audience; Crustaceans have to cyclically replace their rigid exoskeleton in order to grow. Most of them harden this skeleton by a calcification process. Some decapods (land crabs, lobsters and crayfish) elaborate calcium storage structures as a reservoir of calcium ions in their stomach wall, as so-called gastroliths. For a better understanding of the cyclic elaboration of these calcium deposits, we studied the ultrastructure of gastroliths from freshwater crayfish by using a combination of microscopic and physical techniques. Because sugars are also molecules putatively involved in the elaboration process of these biomineralizations, we also determined their carbohy…

Melhoramento ético das práticas em saúde: Comitês de Bioética em Espanha e Brasil

2017

O compartilhamento solidário de experiências entre Brasil e Espanha reposiciona a importância de novos espaços democráticos de participação cidadã e debate ético-político, suscitando questões como: a participação em Comitês Bioéticos pode ir em direção às necessiades-interesses sociais presentes na singularidade da relação profissional-paciente e equipe de saúde? No Brasil, a participação dos profissionais em fóruns construídos para ampliação do controle social e debate da ética, avança como permanente desafio. A ampliação da deliberação em coletivos de debate e equipes de saúde, precisa assumir novo sentido público social na construção da relação profissional-usuário-sistema de saúde-socie…

Do native white-clawed crayfish impact macroinvertebrate assemblages in Mediterranean limestone headwaters?

2019

Crayfish are among the largest aquatic macroinvertebrates in rivers and streams. Their trophic ecology is important for the understanding of the functioning of benthic communities. This is relevant in key areas, such as headwaters, as they partly condition the processes occurring downstream. To shed light on the effects of native white-clawed crayfish,Austropotamobius pallipes, on local macroinvertebrate assemblages from running headwaters, a three-month mesocosm-based field study was designed. Collection and subsequent analysis of benthic samples under different crayfish density levels yielded a set of metrics indicative of short-term impacts at general and taxonomic scales. Neither signif…

Invasive crayfish increase habitat connectivity: a case study in a large boreal lake

2013

Several studies have shown that distinct compartments of lake ecosystems are coupled via transportation of organic matter, nutrients and energy across habitat boundaries. Here we evaluate the potential of the invasive signal crayfish (Pacifastacus leniusculus (Dana)) to modify energy pathways in large boreal lakes. Using a stable isotope mixing model and calculation of the isotopic niches we estimated the contribution of different food sources to the diets of crayfish captured from different habitats, and from that inferred their potential to transport energy across the littoral-profundal gradient. The crayfish caught from the littoral area utilized mainly littoral food sources, whereas the…
