Interpersonal Ties

Social networks and interpersonal ties are critical to social movements. They help recruit members, sustain organizations, nourish participants' movement identities, and disseminate information. Scholarship has pointed to the formative role of social media and other information and communication technologies in online and offline mobilization. Questions remain, however, regarding how online social and friendship networks shape social movements. In this article, I draw from literature on social networks, online mobilization, and women's movements to examine the role of online feminist social networks in feminist mobilization. Presenting qualitative data from a racially and geographically heterogeneous group of college feminists, I argue that Facebook and feminist blogs enlarge and nourish feminist networks, create online feminist communities, expand recruitment bases for online and offline mobilization, and increase opportunities for online interaction with adversaries. Finally, I consider generational shifts in the feminist movement, and the broader relationship between friendship networks and online and offline mobilization.

The Media

The 1970s expansion of free radio stations throughout Europe and the experiences of that movement over the following years encouraged diverse reflections on, and experiments with, the ways of using media and new technologies. Of course the experience of Radio Alice and other free radio stations in the Italy of the late 1970s only became possible when the radio as a communication tool became affordable and technically accessible to a new social subject – the student movement and social movements predominantly consisting of young people. What left the deepest mark on the period, however, was a fundamental change in the attitude of social and political movements to the media.

The Creation

Network society and the new forms of engagementThe popularization of the Internet in the 1990s marked the beginning of socio-cultural changes that have led to the creation of the network society. Networking has covered many spheres – social, cultural, political and economic. Along with social changes, new problems and risks associated with new technologies have emerged. It provoked the beginning of networked social movements, which regained technological tools in a subversive way, using an insect-type of attack, based on the structure of the swarm. One form of such an attack are subversive hacktivist actions, which have a deep performative character. Perhaps it is because of this extraordinary performative potential that the network, along with the new ways of communication, have become a source of tools, both in the artistic and social field. Społeczeństwo sieci a nowe formy zaangażowaniaSpopularyzowanie w latach 90. ubiegłego wieku internetu zapoczątkowało przemiany społeczno-kulturowe, które doprowadziły do powstania społeczeństwa sieciowego. Usieciowienie objęło wiele sfer – społeczną, kulturową, polityczną i ekonomiczną. Wraz ze zmianami społecznymi pojawiły się nieznane dotąd problemy i zagrożenia związane z nowymi technologiami. Spowodowało to powstanie usieciowionych ruchów społecznych, które w subwersywny sposób zaczęły odzyskiwać narzędzia technologiczne, posługując się insektalnym rodzajem ataku, opartym o strukturę roju. Jedną z form takiego ataku są subwersywne działania hacktywistyczne, o głęboko performatywnym charakterze. Być może właśnie z powodu niezwykłego potencjału performatywnego sieć, wraz z nowymi sposobami komunikacji, stała się źródłem pozyskiwania narzędzi zarówno na polu artystycznym, jak i społecznym.

Potential Impact

The paper will deal with concept and range of transnational social movements at the beginning of 21st century, which is a period characterized by huge growth of importance of new technologies and Internet. We will be interested in the role of transnational social movements which base or at least overwhelmingly organize their activity through Internet and social networks; ?Avaaz? will be taken as an example since it is the most popular activist community at the mentioned network. The key aim will be to describe and partly explain the possibilities that Internet provides for functioning of movements, but also to give indications of strategic and tactical changes in their actions, as well as of dangers such type of technology can cause in relation to practical social and political consequences. Firstly, it will shortly be spoken about the concept of transnational social movements, then about the relation between Internet and democracy, conditions that lead to development of new practices such as direct democracy or e-democracy and about the political participation on the Internet. Then the focus will move to ?Avaaz? movement, its recent features and activities, the ethics of this movement that might be defined as cosmopolitan, but also to critics that might be directed to ?Avaaz?. The final part of the paper will be devoted to considerations on transnational social movement?s future and their real and potential impact on emergence of global civil society, in order to assess the achievements of this particular and similar movements.

Gas Pressures

Only recently it became possible to expand scanning electron microscopy to low vacuum and atmospheric pressure through the introduction of several new technologies. In principle, only the specimen is provided with a controlled gaseous environment while the optical microscope column is kept at high vacuum. In the specimen chamber, the gas can generate new interactions with i) the probe electrons, ii) the specimen surface, and iii) the specimen-specific signal electrons. The results of these interactions yield new information about specimen surfaces not accessible to conventional high vacuum SEM. Several microscope types are available differing from each other by the maximum available gas pressure and the types of signals which can be used for investigation of specimen properties.Electrical non-conductors can be easily imaged despite charge accumulations at and beneath their surface. At high gas pressures between 10-2 and 2 torr, gas molecules are ionized in the electrical field between the specimen surface and the surrounding microscope parts through signal electrons and, to a certain extent, probe electrons. The gas provides a stable ion flux for a surface charge equalization if sufficient gas ions are provided.

Abstract P-type ATPases transport ions across biological membranes against concentration gradients and are essential for all cells. They use the energy from ATP hydrolysis to propel large intramolecular movements, which drive vectorial transport of ions. Tight coordination of the motions of the pump is required to couple the two spatially distant processes of ion binding and ATP hydrolysis. Here, we review our current understanding of the structural dynamics of P-type ATPases, focusing primarily on Ca2+ pumps. We integrate different types of information that report on structural dynamics, primarily time-resolved fluorescence experiments including single-molecule Förster resonance energy transfer and molecular dynamics simulations, and interpret them in the framework provided by the numerous crystal structures of sarco/endoplasmic reticulum Ca2+-ATPase. We discuss the challenges in characterizing the dynamics of membrane pumps, and the likely impact of new technologies on the field.

Meiotic CENP-C is a shepherd: bridging the space between the centromere and the kinetochore in time and space

Meiosis I

Abstract While many of the proteins involved in the mitotic centromere and kinetochore are conserved in meiosis, they often gain a novel function due to the unique needs of homolog segregation during meiosis I (MI). CENP-C is a critical component of the centromere for kinetochore assembly in mitosis. Recent work, however, has highlighted the unique features of meiotic CENP-C. Centromere establishment and stability require CENP-C loading at the centromere for CENP-A function. Pre-meiotic loading of proteins necessary for homolog recombination as well as cohesion also rely on CENP-C, as do the main scaffolding components of the kinetochore. Much of this work relies on new technologies that enable in vivo analysis of meiosis like never before. Here, we strive to highlight the unique role of this highly conserved centromere protein that loads on to centromeres prior to M-phase onset, but continues to perform critical functions through chromosome segregation. CENP-C is not merely a structural link between the centromere and the kinetochore, but also a functional one joining the processes of early prophase homolog synapsis to late metaphase kinetochore assembly and signaling.
