The Origins of Social Ventures
2021
This chapter addresses the social venture as a form of organization that has a role in the current society. In an economy based on markets, the intervention of multiple actors by itself—like governments, social movements, charity, and social ventures—cannot ensure the mechanisms necessary to the proper working of the system. In this way, markets present a set of failures and externalities that government action tries to solve. However, government action is limited due to a set of circumstances. Social movements and charity emerge to overcome the government’s limitations. Social entrepreneurship, as the last organization analyzed in this chapter, arises when social movements and charities fa…
Construyendo comunes para el derecho a la ciudad a través de la innovación social colectiva en la distribución y consumo: explorando un marco concept…
2022
En la actual crisis urbana, el nuevo municipalismo reclama la reconstrucción de comunes urbanos para avanzar en el derecho a la ciudad. Señala al respecto la importancia de los movimientos sociales y de la acción pública municipal para generar procesos de innovación social “desde abajo”. Sin embargo, no se ha explorado suficientemente la literatura sobre innovación social con miras a comprender la construcción de comunes urbanos. Por ello, este trabajo propone, a partir de la literatura sobre innovación social de base, un marco para explorar prácticas de generación de comunes desde la ciudadanía, así como políticas municipales que pueden articularse para apoyarlas. El marco se emplea para e…
Hand trajectories of vertical arm movements in one- G and zero- G environments
1998
The purpose of the present experiment was to study the way in which the central nervous system (CNS), represents gravitational force during vertical arm pointing movements. Movements in upward (against gravity) and downward (with gravity) directions, with two different mass loads (hand empty and with a hand-held 0.5-kg weight) were executed by eight subjects in a normal gravitational environment. Movements by two cosmonauts, in the two directions, were also tested in a state of weightlessness. Analyses focused upon finger trajectories in the saggital plane. Subjects in a normal gravitational environment showed curved paths for both directions and weight conditions. In addition, downward mov…
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 …
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…
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 …
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…
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 …
Helena Niemirowska Syrkus. Graphic Analysis of the ‘House of Dr. N. in Warsaw’
2015
The paper proposes a graphic re-reading of the “House of Dr. N. in Warsaw” that Helena Niemirowska, female pioneer of Modern Movement, designed in 1932. The building, on two levels, shows in its form a strict geometric layout and a three parted-subdivision plan in which she defines the functional inside layout both at the ground floor and at the first one. Helena combines Suprematism and the Modern Movement, cultural influences that are revealed, as well as in her other projects, by surfaces, colours and volumes of seemingly static treatment.
The changing role of students' representation in Poland: an historical appraisal
2014
Student representation in Poland has a relatively short but turbulent history. This article offers an historical appraisal of the development of student representation at the national level in the context of rapid and deep structural changes in Polish higher education. Based on a desktop analysis of official documentation, legislation, ideological declarations and background (first-hand) information provided by student leaders, the article reconstructs the establishment of the first independent self-governing student organisation in the country. In so doing, the paper pays particular attention to the emergence, institutionalisation as well as legitimacy challenges facing student bodies eith…
