As forms of private self-regulation, multi-stakeholder initiatives have emerged as an important empirical phenomenon in global governance processes. At the same time, MSIs are also theoretically intriguing because of their inherent double nature. On the one hand, MSIs spell out CSR standards that define norms for corporate behavior. On the other hand, MSIs are also the result of corporate and stakeholder behavior. We combine the perspectives of institutional theory and club theory to conceptualize this double nature of MSIs. Based on (...) a stage model that looks at the interplay of actor and institutional dynamics, we generate insights into why actors join a voluntary MSI, how the various motivations and intentions of the actors influence the standard development, and how these as well as the MSI design are subsequently influenced by both external and internal dynamics.

A 22-month longitudinal study of (self)employed disabled workers (_Following the preference of the lead author who identifies as disabled, the linguistic self-presentation by our participants, the precedent of _(Hein and Ansari, Academy of Management Journal 65:749–783, 2022)_, and the clarification note included in Jammaers & Zanoni’s recent review of ableism _(Jammaers and Zanoni, Organization Studies 42:429–452, 2021)_, we chose, and consistently use, the term “disabled employees” throughout the paper. We do so to underscore the premise of the social model of (...) disability, which explains that “people are disabled first and foremost by society, not by their individual, biological impairment. To us this term most clearly highlights that it is society (and possibly organizations) that disable and oppress people with impairments, by preventing their access, integration and inclusion to all walks of life, making them ‘disabled’.” _(Jammaers and Zanoni, Organization Studies 42:429–452, 2021_: 448_)) models the growing centrality of the body in meaning-making. We inductively explain how body dramas of suffering or thriving initially instigate cycles of meaning deflation and inflation at work. Our disjunctive process model shows that, at the beginning of the pandemic, disabled workers performed either dramas of suffering or on dramas of thriving. However, as the global pandemic unfolded, disabled workers begun crafting composite dramas that deliberately juxtaposed thriving and suffering. This conjunctive process model stabilized meaning-making at work by acknowledging the duality of the disabled body, as both anomaly and asset. Our findings elaborate, and bridge, emerging theories of body work and recursive meaning-making to explain how disabled workers explicitly enroll their bodies to make meaning at work during periods of societal upheaval.

In this paper, we study the genesis and evolution of geometric ideas and techniques in investigations of movable singularities of algebraic ordinary differential equations. This leads us to the work of Mihailo Petrović on algebraic differential equations and in particular the geometric ideas expressed in his polygon method from the final years of the nineteenth century, which have been left completely unnoticed by the experts. This concept, also developed independently and in a somewhat different direction by Henry Fine, generalizes the (...) famous Newton–Puiseux polygonal method and applies to algebraic ODEs rather than algebraic equations. Although remarkable, the Petrović legacy has been practically neglected in the modern literature, although the situation is less severe in the case of results of Fine. Therefore, we study the development of the ideas of Petrović and Fine and their places in contemporary mathematics. (shrink)

Chelicerates (scorpions, horseshoe crabs, spiders, mites and ticks) are the second largest group of arthropods and are of immense importance for fundamental and applied science. They occupy a basal phylogenetic position within the phylum Arthropoda, and are of crucial significance for understanding the evolution of various arthropod lineages. Chelicerates are vectors of human diseases, such as ticks, and major agricultural pests, such as spider mites, thus this group is also of importance for both medicine and agriculture. The developmental genetics of (...) chelicerates is poorly understood and a challenge for the future progress for many aspects of chelicerate biology is the development of a model organism for this group. Toward this end, we are developing a chelicerate genetic model: the two‐spotted spider mite Tetranychus urticae. T. urticae has the smallest genome of any arthropod determined so far (75 Mbp, 60% of the size of the Drosophila genome), undergoes rapid development and is easy to maintain in the laboratory. These features make T. urticae a promising reference organism for the economically important, poorly studied and species‐rich chelicerate lineage.

La formalización puede ser considerada como un proceso natural del pensamientoo de todo proceso cognitivo en la medida en que el lenguaje comúnes en sí mismo un proceso de formalización. Pero, ¿qué se puede entenderpor formalización en el marco de la física?, ¿hay una distinción de base conesos procesos comunes de formalización?, ¿es la formalización sinónimo dematematización? y ¿en qué se diferencian? En el artículo se caracterizancuatro maneras diferentes de formalizar, pretendiendo con ello estableceruna base más adecuada para responder este (...) tipo de preguntas: 1)formalización de carácter pragmático, 2) aplicación de las matemáticas 3)axiomatización de las teorías físicas y unificación de campos fenoménicos y4) matematización de un campo fenoménico.
