Magnetic-field measurements of T Tauri stars in the Orion Nebula cluster

We present an analysis of high-resolution ($R \sim 50,000$) infrared K-band echelle spectra of 14 T Tauri stars in the Orion Nebula Cluster. We model Zeeman broadening in three magnetically sensitive \ion{Ti}{1} lines near $2.2\ \mu$m and consistently detect kilogauss-level magnetic fields in the stellar photospheres. The data are consistent in each case with the entire stellar surface being covered with magnetic fields, suggesting that magnetic pressure likely dominates over gas pressure in the photospheres of these stars. These very strong magnetic fields might themselves be responsible for the underproduction of X-ray emission of T Tauri stars relative to what is expected based on main-sequence star calibrations. We combine these results with previous measurements of 14 stars in Taurus and 5 stars in the TW Hydrae association to study the potential variation of magnetic-field properties during the first 10 million years of stellar evolution, finding a steady decline in total magnetic flux with age.Comment: 34 pages, 17 figures, published in ApJ, 2011, 729, 8

MS-115: The Notarangelo Collection of the Louis A. Parsons Papers

The collection was created from two different sets of letters and papers related to Louis A. Parsons, obtained from Thomas Notarangelo in 2008. Notarangelo purchased the papers at auction. Both sets consisted of correspondence of both professional and personal nature; one set consisting of correspondence from Parsons’ life before he became a professor at Gettysburg, and the other focusing mainly around the issue of his dismissal from Gettysburg College in 1925. The entire collection consists primarily of the correspondence written and received by Parsons. Special Collections and College Archives Finding Aids are discovery tools used to describe and provide access to our holdings. Finding aids include historical and biographical information about each collection in addition to inventories of their content. More information about our collections can be found on our website http://www.gettysburg.edu/special_collections/collections/.https://cupola.gettysburg.edu/findingaidsall/1104/thumbnail.jp

From modern workplaces to modern families – re-envisioning the work–family conflict

The Modern Workplaces Consultation 2011 set the foundations for the current revisions to work–family rights in the UK. They are underpinned by a desire to make modern workplaces more flexible and responsive to the needs of working families. The Children and Families Act 2014 implements, in part, the consultation’s proposals, but falls far short of its most significant recommendations. Nevertheless, it does extend access to work–family rights to some alternative working family models. The analysis undertaken here, however, indicates that this is limited to families that most closely conform to the dual-partnered working family model. Drawing from Fineman, Herring and McGlynn’s references to relationships of care, it is argued that instead of re-branding current rights the government should re-envision the concept of the family and family care. It is only through renegotiating the categories of caregiving recognised in law that the needs of modern working families will genuinely be met

Bays in Peril: A Forecast for Freshwater Flows to Texas Estuaries

Takes a look at increasing water demands in Texas, and what would happen to the inflows to the seven major estuaries if existing water permits were fully used and wastewater reuse increased. Provides recommendations for action

Continuously variable voltage-controlled phase shifter

Phase shifter circuit adjusts the phase relationship between a locally generated reference frequency and a received RF signal applied to a phase-coherent detector. It is small enough to be integrated into a receiver subassembly and operates on command from remote control panels

Two Screen Viewing and Social Relationships. Exploring the invisible backchannel of TV viewing

Use of social networks to create a real-time backchannel of\ud communication among viewers of television programs has been documented, and has been termed “two-screen viewing,” with one screen devoted to the program being watched, and a second screen (usually a laptop, tablet, or cell/mobile\ud phone) devoted to maintaining the backchannel. Prior research has examined twoscreen viewing through content analysis of social media posts. However, little has been done to explore the way in which two screen viewing qualitatively changes the viewing experience, or to understand how this behavior contributes to the construction or maintenance of social relationships. Couch (1992) noted that social interaction require a shared focus, a social objective, and congruent functional identities. The first screen program provides the shared focus. Using online interviews, this small pilot project seeks to discover whether social objectives and congruent functional identities are established through two-screen viewing. That is, the study explores how one might go about determining whether this communication actually contributes to social relationships or serves some other, asocial purpose. The present study is a small pilot project only. Preliminary\ud data suggest that there are two types of two-screen viewing defined by different degrees of visible and invisible online practice
