The reciprocal relationship between the state and union formation across Western Europe: policy dimensions and theoretical considerations
Although cohabitation and childbearing within cohabitation has increased dramatically in Europe over the past decades, the variation across Europe remains remarkable. Most studies on changing union formation have not explicitly addressed how state policies may be facilitating cohabitation or, alternatively, stalling the increase of cohabitation by privileging marriage. Indeed, the relationship between policies and union formation is complicated, as states may have passed legislation in response to increasing cohabitation. As a first step to understanding this reciprocal relationship, we provide here an overview of the policies that may impact union formation. Drawing on secondary sources and legal documents, we describe the policy dimensions that regulate the relationship between couples, and between couples and their children. We also discuss theoretical issues and explore examples from across Western Europe. As a whole, this overview raises questions about the changing âinstitutionâ of marriage, as well as the increasing âinstitutionalizationâ of cohabitation.Europe, cohabitation
Loop homology of spheres and complex projective spaces
In his Inventiones paper, Ziller (Invent. Math: 1-22, 1977) computed the
integral homology as a graded abelian group of the free loop space of compact,
globally symmetric spaces of rank 1. Chas and Sullivan (String Topology,
1999)showed that the homology of the free loop space of a compact closed
orientable manifold can be equipped with a loop product and a BV-operator
making it a Batalin-Vilkovisky algebra. Cohen, Jones and Yan (The loop homology
algebra of spheres and projective spaces, 2004) developed a spectral sequence
which converges to the loop homology as a spectral sequence of algebras. They
computed the algebra structure of the loop homology of spheres and complex
projective spaces by using Ziller's results and the method of Brown-Shih (Ann.
of Math. 69:223-246, 1959, Publ. Math. Inst. Hautes \'Etudes Sci. 3: 93-176,
1962). In this note we compute the loop homology algebra by using only spectral
sequences and the technique of universal examples. We therefore not only obtain
Zillers' and Brown-Shihs' results in an elementary way, we also replace the
roundabout computations of Cohen, Jones and Yan (The loop homology algebra of
spheres and projective spaces, 2004) making them independent of Ziller's and
Brown-Shihs' work. Moreover we offer an elementary technique which we expect
can easily be generalized and applied to a wider family of spaces, not only the
globally symmetric ones.Comment: 10 pages, 8 figure

Staurosira magallanesica, a replacement name for Staurosira patagonica
Staurosira patagonica M.L.Garcia, Maidana, Ector & E.Morales described a new species found in material of Maar Magallanes, Patagonia, Argentina and other lakes in southern Patagonia. This new species was analysed in detail by light and electron microscopy and a comprehensive description is given in Garcia et al. (2017: 107, 114, figs 2-45). However, this name is a later homonym of Staurosira patagonica Cleve, 1882. If we compare our species to Cleveâs illustration (Cleve 1882: pl. 16: fig. 13), we can easily differentiate the two by their general valve outline and morphometric data. As pointed out by Garcia et al. (2017), re-examination of the type material of members of the Fragilariaceae is needed to confirm identities, establish taxonomic boundaries and to facilitate identification, and this is also the case with Staurosira patagonica Cleve. A new name is, however, required for Staurosira patagonica M.L.Garcia, Maidana, Ector & E.Morales as it is an illegitimate name: Staurosira magallanesica M.L.Garcia, Maidana, Ector & E.Morales nom. nov. Replaced synonym: Staurosira patagonica M.L.Garcia, Maidana, Ector & E.Morales Nova Hedwigia, Beiheft 146: 107, 114, figs 2-45, 2017, nom illeg., non Staurosira patagonica Cleve 1882 Ăfversigt af Kongliga Svenska Vetenskaps-Akademiens Förhandlingar 38(10): 13, pl. 16: fig. 13, 1882 â1881â. Etymology: we have derived the specific epithet from the name of the paleolake Maar Magallanes where this new species was found for the first time by N.I. Maidana (Maidana & Corbella 1997).Fil: GarcĂa, MarĂa LujĂĄn. Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales. Departamento de Biodiversidad y BiologĂa Experimental; Argentina.

Words to cook by: Changing meanings of eating local in Humboldt County
Humboldt County has an active food system of small, sustainable farms and a vibrant cottage food industry. Yet, this system fails to address the needs of a diverse population that struggles with a disproportionate degree of poor health outcomes. In order to understand the unique challenges facing the regionâs food system â and how local government and advocacy groups should begin to address healthy food policy - this research thesis analyzes key texts about food, which illustrate the language and ideologies of eating local in Humboldt County. This research thesis found that the concept of eating local â consuming foodstuffs produced in close proximity or naturally indigenous to the environment â has been both a cause and effect of cultural change in Humboldt County. In order to understand how the community talks about food today â with âeating localâ being a central element of the rhetoric â this thesis analyzed a collection of regional cookbooks for historic perspective. Functioning as textual archives about food, cookbooks both reflect and construct discourse about Humboldt Countyâs food system and eating local today. Through this research, itâs evident that heritage Humboldt County foods - specifically salmon, oysters, crab, beef, and dairy â decreased in cultural significance throughout the 20thcentury. Yet, in recent years, the discourse around eating local has amplified, with language about improving community health and eating local tightly embedded. In effort to create a food system that truly feeds everyoneâs needs, this research thesis explains how the narrative around the meaning of âeating localâ has shifted over time
Descartes Comes Out of the Closet
While âDescartes Comes Out of the Closetâ is ostensibly about a young womanâs journey to Paris, the descriptive detail borrows language and images from Cartesian coordinate geometry, dualistic philosophy, neuroanatomy (the pineal), and projections of three dimensions onto planes. This mathematical universe is counterpointed in the natural language of the suppressed love story that locates the real in the human. Thus, at the heart of the story is the tension between competing notions of mathematics, i.e., as either an independent realm apart from history or as a culturally produced and historical set of practices. Of course, the central character proves to suffer from a pineal gland tumor, so the mechanisms of reconciliation arenât functioning very well
How to Measure a Coastline
The infinite shoreline of Lake Superior is embedded in the mathematical imagination, the memory of its stony beaches, and in the unifying consciousness that holds them all, just as the lake itself lies cradled in the land. The narrator of these paradoxes finds the lake, its border, and the calculi strewn along its shore a place a space between worlds where we rediscover that we canât measure what we canât locate, and canât locate what we canât measure, even the versions of ourselves
