Twisted cohomology of arrangements of lines and Milnor fibers

Let \A be an arrangement of affine lines in \C^2, with complement \M(\A). The (co)homo-logy of \M(\A) with twisted coefficients is strictly related to the cohomology of the Milnor fibre associated to the conified arrangement, endowed with the geometric monodromy. Although several partial results are known, even the first Betti number of the Milnor fiber is not understood. We give here a vanishing conjecture for the first homology, which is of a different nature with respect to the known results. Let $\Gamma$ be the graph of \emph{double points} of \A: we conjecture that if $\Gamma$ is connected then the geometric monodromy acts trivially on the first homology of the Milnor fiber (so the first Betti number is combinatorially determined in this case). This conjecture depends only on the combinatorics of \A. We prove it in some cases with stronger hypotheses. In the final parts, we introduce a new description in terms of the group given by the quotient ot the commutator subgroup of \pi_1(\M(\A)) by the commutator of its \emph{length zero subgroup.} We use that to deduce some new interesting cases of a-monodromicity, including a proof of the conjecture under some extra conditions.Comment: 2 m pages, 7 figure

School Public Relations: Relating with LEP Families

The purpose of this paper was to examine newsletters disseminated by school public relations programs to their community in districts where Spanish is the primary home language. A content analysis examined district newsletters of school districts located in the Rio Grande Valley of Texas. The examination of district-issued newsletters determined the percentage of stories written in English or Spanish to compare with the demographic make-up, specifically the percentage of the non-English speaking parents of the district and the percentage of Limited English Proficient students. Stories were also analyzed to determine whether there were recurring themes in the English versus Spanish stories. This helped to determine if the publications, created and circulated by the school district, were reflective of the demographics of their respective school districts

Practice parameters for the treatment of colonic diverticular disease: Italian Society of Colon and Rectal Surgery (SICCR) guidelines

The mission of the Italian Society of Colorectal Surgery (SICCR) is to optimize patient care. Providing evidence-based practice guidelines is therefore of key importance. About the present report it concernes the SICCR practice guidelines for the diagnosis and treatment of diverticular disease of the colon. The guidelines are not intended to define the sole standard of care but to provide evidence-based recommendations regarding the available therapeutic options

Virginia L. Campbell, The Tombs of Pompeii: Organization, Space and Society, New York, 2015.

Virginia L. Campbell in her book “The Tombs of Pompeii: Organization, Space and Society” offers a comprehensive overview of graves, tombs and development of the necropoleis in Pompeii through aspects of spatial and social organization. The book is organized in seven chapters, three appendices (catalogues of graves, tombs and funerary inscriptions), index, and illustrations which correspond well to the text. The book is a result of research undertaken by the author for her dissertation based on analysis of extensive documentation and series of very diverse scientific works dealing with Pompeii and their necropoleis but concentrating mostly on the most famous and most decorative finds and tombs without a systematic study of entire scope of the sepulchral area. In her study, the author attempted to solve some crucial questions, primarily if detailed analysis of each individual burial area can reveal social, economic, legal or cult traditions and regulations (possibly specific only for Pompeii);ways in which funerary monuments reflect behaviour of the individuals or groups, and administrative procedures necessary for organization of a funeral. The author answers these questions in the discussion parts of the book, from the third to the sixth chapter
