What is Business Organizing for? – The Role of Business in Society Over Time

Resumen | En este trabajo quiero presentar una cronología convencional del concepto raza que marca un movimiento en el cual raza cambia de ser una idea basada en la cultura y el medio ambiente, a ser algo biológico, inflexible y determinante, para luego volver a ser una noción que habla de la cultura.Resumo cómo la idea de raza ha cambiado a través del tiempo, mirando necesariamente el rol que ha desempeñado la ciencia, y enfocando los diferentes discursos de índole natural-cultural sobre los cuerpos, el medio ambiente y el comportamiento, en los cuales las dimensiones culturales y naturales siempre coexisten.“La naturaleza” no puede ser entendida solamente como “la biología” y ni la naturaleza ni la biología necesariamente implican sólo el determinismo, la fijeza y la inmutabilidad Estar abiertos a la coexistencia de la cultura y la naturaleza y a la mutabilidad de la naturaleza nos permite ver mejor el ámbito de acción del pensamiento racial.Race, Science and Society Abstract | In this article I present and critique a standard chronology of race as, first, a concept rooted in culture and environment, and later in human biology and determinism, and finally back to culture alone.I will outline changing understandings of race over time, with some attention to the role of science, broadly understood, and on the continuing but changing character of race as a natural-cultural discourse about organic bodies, environments and behavior, in which both cultural and natural dimensions always co-exist.“Nature” is not to be understood simply as “biology,” and neither nature nor biology necessarily imply the fixity and determination that they are often assumed nowadays to involve.Being open to the co-existence of culture and nature and the mutability of the latter allows us to better comprehend the whole range of action of racial thinking.

Over Time

By many estimates the majority of adults over age 65 have two or more chronic medical conditions (multimorbidity) and are consequently at increased risk of adverse functional outcomes. Nonetheless, many older adults with multimorbidity are able to maintain high levels of function and retain good quality of life. Research presented here is designed to understand the influences that help ensure better functional outcomes in these older adults. This chapter presents findings that draw on data from the Midlife in the United States study. The independent and interactive contributions of diverse factors to multimorbidity and changes in multimorbidity over time are reviewed. The degree that multimorbidity increases risk of cognitive impairment and disability is examined. The role of inflammation as a mediator is considered. Multimorbidity is increasingly the norm for older adults, so better understanding of factors contributing to variability in multimorbidity-related outcomes can lead to improved quality of life.

Over Time

Zebrafish spontaneously use distance and directional relationships among three-dimensional extended surfaces to reorient within a rectangular arena. However, they fail to take advantage of either an array of freestanding corners or an array of unequal-length surfaces to search for a no-longer-present goal under a spontaneous cued memory procedure, being unable to use the information supplied by corners and length without some kind of rewarded training. The present study aimed to tease apart the geometric components characterizing a rectangular enclosure under a procedure recruiting the reference memory, thus training zebrafish in fragmented layouts that provided differences in surface distance, corners, and length. Results showed that fish, besides the distance, easily learned to use both corners and length if subjected to a rewarded exit task over time, suggesting that they can represent all the geometrically informative parts of a rectangular arena when consistently exposed to them. Altogether, these findings highlight crucially important issues apropos the employment of different behavioral protocols (spontaneous choice versus training over time) to assess spatial abilities of zebrafish, further paving the way to deepen the role of visual and nonvisual encodings of isolated geometric components in relation to macrostructural boundaries.

Over Time

The crucial role of microbes in the evolution, development, health, and ecological interactions of multicellular organisms is now widely recognized in the holobiont concept. However, the structure and stability of microbiota are highly dependent on abiotic and biotic factors, especially in the gut, which can be colonized by transient bacteria depending on the host’s diet. We studied these impacts by manipulating the digestive microbiota of the detritivore Armadillidium vulgare and analyzing the consequences on its structure and function. Hosts were exposed to initial starvation and then were fed diets that varied the different components of lignocellulose. A total of 72 digestive microbiota were analyzed according to the type of the diet (standard or enriched in cellulose, lignin, or hemicellulose) and the period following dysbiosis. The results showed that microbiota from the hepatopancreas were very stable and resilient, while the most diverse and labile over time were found in the hindgut. Dysbiosis and selective diets may have affected the host fitness by altering the structure of the microbiota and its predicted functions. Overall, these modifications can therefore have effects not only on the holobiont, but also on the “eco-holobiont” conceptualization of macroorganisms.

AbstractWe used high resolution micromechanical force sensors to study the in vivo mechanical response of embryonic Drosophila neurons. Our experiments show that Drosophila axons have a rest tension of a few nN and respond to mechanical forces in a manner characteristic of viscoelastic solids. In response to fast externally applied stretch they show a linear force-deformation response and when the applied stretch is held constant the force in the axons relaxes to a steady state value over time. More importantly, when the tension in the axons is suddenly reduced by releasing the external force the neurons actively restore the tension, sometimes close to their resting value. Along with the recent findings of Siechen et al (Proc. Natl. Acad. Sci. USA 106, 12611 (2009)) showing a link between mechanical tension and synaptic plasticity, our observation of active tension regulation in neurons suggest an important role for mechanical forces in the functioning of neurons in vivo.
