Dynamics and elasticity of the fibronectin matrix in living cell culture visualized by fibronectin–green fluorescent protein

Fibronectin (FN) forms the primitive fibrillar matrix in both embryos and healing wounds. To study the matrix in living cell cultures, we have constructed a cell line that secretes FN molecules chimeric with green fluorescent protein. These FN–green fluorescent protein molecules were assembled into a typical matrix that was easily visualized by fluorescence over periods of several hours. FN fibrils remained mostly straight, and they were seen to extend and contract to accommodate movements of the cells, indicating that they are elastic. When fibrils were broken or detached from cells, they contracted to less than one-fourth of their extended length, demonstrating that they are highly stretched in the living culture. Previous work from other laboratories has suggested that cryptic sites for FN assembly may be exposed by tension on FN. Our results show directly that FN matrix fibrils are not only under tension but are also highly stretched. This stretched state of FN is an obvious candidate for exposing the cryptic assembly sites.

Culture Industries in a Postindustrial Age: Entertainment, Leisure, Creativity, Design

This article reviews the evolution of the concept of culture industries, when neither industry nor culture themselves are today what they were at the time when the term was coined. It attempts to explain the dilution of the term into more nebulous terms (“leisure industries,” “entertainment industries” or “creative industries”) and suggests new challenges for the research on culture industries. What is at stake is no longer an application of a Fordist production to culture, a one-directional mass communication and a mediation by experts, but rather: (1) a cultural experience which is no longer clearly separated from other activities (leisure in general, consumption and even work); (2) the communicative explosion of all industrial production in a media environment, where industrialized symbolic products are mixed with culturalized industrial products; and (3) the empowerment of the recipient, which on one hand ignores the traditional experts and on the other leads to post-productive (recreational and even creative) cultural practices.

Digital Fabrication and Free Culture. One More Minor Becoming?

Diferentes autores se refieren a la fabricación digital como la Tercera Revolución Digital, después de las revoluciones de la computación y la comunicación. Como ocurriera con las dos revoluciones precedentes, se generaron grandes expectativas en torno a las virtualidades políticas de estas nuevas tecnologías para dar lugar a relaciones de producción más libres e individuos más autónomos. Sin embargo, como también ocurriera con la computación y la comunicación, lo que realmente está ocurriendo demuestra que las supuestas virtualidades no llegarán a hacerse actuales sin una intensa implicación, organización y trabajo por parte de sectores activistas técnicos y sociales. Se discute el caso de la compra corporativa de la empresa pionera de hardware libre Makerbot, como ejemplo de la situación y punto de inflexión en las expectativas de los nuevos tecno-visionarios. Para concluir se propone una serie de posibles estrategias que podrían promover el desarrollo efectivo de un ecosistema libre y open source de fabricación digital.

Eliciting Euphoria Online: The Aesthetics of “ASMR” Video Culture

“Autonomous Sensory Meridian Response” (ASMR) is a term that has emerged online to describe a mysterious tingling sensation that some people experience in response to particular audiovisual and interpersonal “triggers.” Initially coalescing via discussion threads on health forums, ASMR culture quickly began using platforms like YouTube and Reddit to exchange trigger videos. This paper frames the emergence of ASMR video culture as an example of how bodies and algorithms are conspiring to bring into being new cultural forms that can seem literally inexplicable on first encounter. Treating videos as “inputs,” judged not as messages to be understood or interpreted but by their ability to elicit particular affective and somatic “outputs,” ASMR communities cultivate a quasi-cybernetic relationship with the moving image, using video as a vehicle for “feeling out” phenomena that seem to thwart linguistic articulation and rational comprehension.

Real leadership and the U.S. Army : overcoming a failure of imagination to conduct adaptive work /

This monograph begins with a case study that provides a means for analyzing the complexity of organizational leadership in the contemporary security environment. As such, it presents a high stakes problem-set that required an operational adaptation by a cavalry squadron conducting combat operations in Baghdad. This problematic reality triggered the struggle to find a creative response to a very deadly problem, while cultural norms served as barriers that prevented the rejection of previously accepted solutions that had proven successful in the past, even though those successful solutions no longer fit in the context of the reality of the present. The case study highlights leaders who were constrained by deeply-held assumptions that inhibited their ability to adapt quickly to a changed environment. The case study then moves on to provide an example of a successful application of adaptive leadership and adaptive work that was performed by the organization after a period of reflection and the willingness to experiment and assume risk. The case study serves as a microcosm of the challenges facing the U.S. Army, and the corresponding leadership framework presented in this monograph can be used as a model for the Army as it attempts to move forward in its effort to make adaptation an institutional imperative. The paper presents a more holistic approach to leadership where the leader transcends that of simply being an authority figure and becomes a real leader who provides a safe and creative learning environment where the organization can tackle and solve adaptive challenges. The paper concludes by recommending that U.S. Army leaders apply Harvard Professor Dean Williams's theory to the challenges confronting the Army's leader development process thereby fostering a culture of adaptive leaders.
