Team Knowledge Networks, Task Dependencies and Coordination: Preliminary Findings from Software Teams

Today’s work increasingly involves teams with fluid boundaries, and members working on multiple projects at a time. To understand how work is effectively coordinated in such complex organizations, we focus on the role of a company’s task dependency network. We integrate three research streams – coordination, team knowledge and social networks to conceptualize multiteam work as a large collaboration with members in multiple functional roles and areas of expertise, with complex task dependency relationships, operating as a coherent and well-coordinated knowledge network. Through this integration and empirical test of associated hypotheses with data from a European software company, our study illustrates how to represent multiple relationships in one complex multiplex network. This extends our understanding of how the various knowledge relationships and individual attribute differences influence the effective coordination in collaborative software development work. We address the concepts of awareness and shared familiarity and how they affect coordination, while keeping our focus on illustrating the power of network analytics to gain nuanced insights into the drivers of effective coordination

En busca de lo excéntrico

This Sociology and Technoscience monograph extends conversations and uses of eccentricity as a methodological tool for doing research within the field of feminist and gender studies. The search for eccentricity responds to the editors’ interest in reflecting on and engaging with different methodological approaches which help deviate from canonical established patterns of research onto unusual and provocative ways of doing research differently. In this collection we have gathered contributions dealing with the analysis of technologies of gender, sexuality and bodies to propose new ways to defocus, dislocate or blur the split between subjects and objects of study. In sum, with this monograph we intend to contribute to gender approaches to science by exploring "eccentrically" the ways feminist and gender scholars think and research otherwise. Feminist modes of knowledge and doing research have traditionally been excluded from academic discourses or denied the merits of their own specificity due to the constitution of the notion of “women” as a sexual differentiated subject. “Women”, as epistemological subject, has been trapped between the unrepresented or unrepresentable due to the articulation of what Michel Foucault calls “technologies of sex” - that is, mechanisms, apparatuses and discourses (legal, pedagogical, medical, demographic, religious or economic) that regulate sexuality.  Following the Foucaultian concept, Teresa De Lauretis (1987) coins the concept of “technologies of gender” to move away from the idea of gender as sexual difference towards its comprehension as a political tool instead. Technologies are hence understood as inseparable from their sociocultural milieus and the semiotic apparatuses which produce women and men, assigning an identity and a position to each individual within the social group.  Este monográfico de Sociología y Tecnociencia explora debates sobre los usos del concepto de excentricidad en el campo de los estudios feministas y de género.  La búsqueda de la excentricidad responde al interés de las editoras por reflexionar sobre enfoques metodológicos que nos ayuden a desviarnos de los patrones canónicos para adentrarnos en formas  transgresoras y diferentes de la investigación. Reunimos contribuciones que versan sobre análisis de las tecnologías de género, sexualidad y corporalidades y proponen formas nuevas de cambiar el enfoque, de dislocar o borrar las fronteras entre sujetos y objetos de estudio. En resumen, con este monográfico intentamos aportar enfoques de género a la ciencia para explorar excéntricamente las formas en las que lxs investigadorxs feministas piensan e investigan de forma alternativa. Tradicionalmente se han excluido los conocimientos y formas de investigar feministas de los discursos académicos. Se les ha negado a menudo los méritos propios de su especificidad y la “mujer”, como sujeto epistemológico, ha quedado atrapada entre lo no representado y lo no representable. siguiendo la articulación de lo que Michel Foucault llamó “tecnologías del sexo”, es decir, mecanismos, aparatos y discursos (legales, pedagógicos, médicos, demográficos, religiosos o económicos) que regulan la sexualidad. Siguiendo a Foucault, Teresa De Lauretis (1987) acuña el concepto “tecnologías de género” para alejarse de la idea de género como diferencia sexual y acercarse a su comprensión como herramienta política. Desde aquí, las tecnologías se entienden como inseparables de sus entornos socioculturales y de los aparatos semióticos que modelan a mujeres y hombres y asignan una identidad y una posición a cada individuo dentro del grupo social

SARS-CoV-2 and its Metaphors

The current SARS-CoV-2 pandemic has brought, as in past pandemics, a series of metaphors and, still, a recent literature about it. In addition to philosophical and economic questions, that have caused an unprecedented crisis and that it is early to evaluate with a proper perspective.La pandemia actual de SARS-CoV-2 ha traído, como en pandemias pasadas, una serie de metáforas y literatura todavía aún reciente en torno a la misma. Además de cuestiones filosóficas y económicas, que han provocado una crisis sin precedente y que es pronto para evaluar con una perspectiva adecuada

17β-Estradiol inhibits proliferation and migration of human vascular smooth muscle cells: similar effects in cells from postmenopausal females and in males

Objectives: Cardiovascular disease is rare in premenopausal women, but increases after the menopause when hormone replacement therapy reduces coronary events. Vascular smooth muscle cell (SMC) proliferation and migration occur in atherosclerosis, restenosis and venous graft disease. We studied the effects of 17β-estradiol on SMC proliferation and migration. Methods: SMC were cultured from saphenous veins of postmenopausal women and age-matched men. Cell growth was determined by 3H-thymidine incorporation and cell counting. Migration of SMC was assessed in 4-well chambers. SMC were seeded in one corner and PDGF-BB in filter paper glued onto the opposite wall. Results: PDGF-BB (5 ng/ml for 24 h) similarly stimulated 3H-thymidine incorporation in female (511 ± 57%; n = 8) and male (528 ± 62%; n = 12) SMC. This was reduced by 17β-estradiol (10−8-10−6 M; female 313 ± 52%; male 337 ± 54%; P < 0.05). PDGF-BB increased the number of SMC (P < 0.0001 at 10 days) obtained from females (153 ± 3%; n = 5) and males (150 ± 4%; n = 5), which was inhibited by 17 β-estradiol (10−6 M; female 134 ± 7%; male 128 ± 5%; P < 0.05). Similar results were obtained with basic fibroblast growth factor. In contrast to 17β-estradiol, another steroid (dexamethasone) had no effects on 3H-thymidine incorporation in these cells stimulated with PDGF-BB. PDGF-BB (0.01-1 ng) stimulated SMC migration (P < 0.05) which was inhibited by 17β-estradiol (10−10-10−6 M; n = 5; P < 0.005). Conclusion: 17β-Estradiol inhibits growth-factor-induced SMC proliferation and migration regardless of gender. These effects of 17β-estradiol may contribute to its cardiovascular protective properties in postmenopausal women during replacement therap

Evaluation of the transport properties of copper ions through a heterogeneous ion-exchange membrane in etidronic acid solutions by chronopotentiometry

[EN] The transport properties of copper chelates across an anion-exchange membrane were investigated by means of chronopotentiometry. Several solutions containing etidronic acid, copper sulfate and potassium chloride were evaluated. Tests were accomplished in a three-compartment reactor using a heterogeneous membrane containing quaternary ammonium functional groups. Results showed a strong relation between the amount of chelated anions and the limiting current density, the electrical resistance and the concentration polarization. An increase in the anionic equivalent charge of the solutions modified the three regions of the current-voltage curves. The acid medium was found to be less favorable because of the possibility of the formation of non-charged species in overlimiting regions. The presence of chloride anions increased the limiting current density, especially when the chloride concentration exceeded the etidronic acid concentration.Authors would like to thank the Institute for Technological Research (IPT), the Institute for Technological Research Foundation (FIPT), to the São Paulo Research Foundation (Fapesp - processes 2012/51871-9, 2014/21943-3 and 2014/13351-9) and the National Council for Scientific and Technological Development.Scarazzato, T.; Panossian, Z.; García Gabaldón, M.; Ortega Navarro, EM.; Tenório, J.; Pérez-Herranz, V.; Espinosa, D.
