Making the Link: Pregnancy Prevention and the New Welfare Era

Making the Link: Pregnancy Prevention in the New Welfare Era offers strategies to prevent unintended pregnancy in an era in which the nation's welfare program has a changed mission, more money, and greater reach. The enactment of the 1996 welfare law allows federal welfare funds to be spent on an array of pregnancy prevention activities and family planning services; furthermore, welfare funds are no longer limited to welfare recipients who receive grants -- funds may be spent on individuals who have never been a part of the welfare system. These fundamental policy changes, along with nearly $8 billion of unspent welfare funds, allow states to consider whether and how to invest in a range of strategies to prevent unintended pregnancy. The law permits, but does not require, any such investment. Nevertheless, a number of states are creating new ways to address unintended pregnancy. Some states are linking welfare offices and family planning services -- through co-location, information dissemination, referrals, case management, education, and training. Others are tapping welfare funds to provide education, information, or services to those who might never enter a welfare office. Some programs target adults, others teens; some include a focus on males. Making the Link seeks to provide insight into different types of links and how to make them work

Towards a \u3ci\u3eLiterary Criticism\u3c/i\u3e: Lowry, Durrell, Dolores, and the alchemical balance between critical and creative writing

I begin this study with the formalistic essays of Michael Oakeshott and Susan Sontag, observing the precarious position of aesthetics in contemporary literary discourse. Rather than fit the novels Under the Volcano and the Alexandria Quartet into normative Kantian or New Critical frameworks, I follow the course of alchemical allusions in Lowry’s novel and relate them to the troubled theme of modern love in Durrell’s, writing in an experiential, plot-driven manner towards a narrative describing the effects of these texts upon my fiction. After I discuss the traces of Sade in Durrell, the metafictional novelette “Dolor” concludes the project, betraying numerous critical themes: the decentered subject, anxieties of authorship, and writing the body as text. My aim is to suggest that if literature is not beholden to logical truth, criticism might follow a more literary course by exposing itself to the elements of fiction—whose assimilative revenge upon theory seems long overdue

Cross Ratio

A question posed in the MAA Monthly is the following: “Given four points A, B, C, and D in order on a line in Euclidean space, under what conditions will there be a point P off the line such that the angles ???APB, ?BPC, and ?CPD have equal measure.” We will present a partial solution of this question using the cross ratio. The cross ratio plays a central role in projective geometry however can be proved using the Law of Sines. The elements of the proofs are comprised of calculus, algebra, and geometry

Year of Meteors: Stephen Douglas, Abraham Lincoln, and the Election That Brought on the Civil War

Examining the Crucial Election of 1860 Walt Whitman called 1860 the “Year of meteors! brooding year! In this volume, Douglas R. Egerton describes the major events of that year’s presidential election campaign and the subsequent secession crisis. The author, who teaches history at Le Mo...

The Mary Lincoln Enigma: Historians on America\u27s Most Controversial First Lady

Trying to Make Sense of a Misunderstood Figure Written without fear or research, books about Abraham Lincoln’s marriage have grossly misrepresented the subject. The worst offenders are Mary Lincoln’s biographers, who resemble defense attorneys rather than impartial historians. They whi...

The Influence of PBL Parameterization on the Practical Predictability of Convection Initiation During the Mesoscale Predictability Experiment (MPEX)

This study evaluates the influence of planetary boundary layer (PBL) parameterizations on short-range (0-15 h) forecasts of convection initiation (CI) within convection-allowing ensembles that utilize sub-synoptic-scale observations collected during the Mesoscale Predictability Experiment (MPEX). Running five thirty-member ensembles with the Advanced Research Weather Research and Forecasting Model (WRF-ARW) with each differing only in the chosen PBL parameterization, forecast skill, PBL sensitivity on the environment in which CI occurred, and the variability within are examined. Three MPEX cases, 19-20 May 2013, 31 May-1 June 2013, and 8-9 June 2013 are considered, each characterized by a different large-scale flow pattern to analyze a wider spectrum of events. Using an object-based method to verify and analyze the forecasts of CI, it was found that none of the Five PBL schemes analyzed significantly improved the forecast skill. The non-local mixing PBL schemes, MYJ and QNSE, had in all cases higher probability of detection (POD) but consequently had a higher false alarm ratio (FAR) resulting from the models overproducing the number of CI objects, with all PBLs, and thus resulting in relative high bias scores as well. The CSI showed only subtle changes between PBL schemes suggesting no one PBL scheme drastically outperforms the other. The temporal distribution of errors associated with the “hits” in the CI object matching showed an approximate normal distribution around a mean of 0-s suggesting little systematic timing bias. While the spatial distribution of errors yielded skewed distributions with on average a mean (median) distance error of just over 44-km (28-km). Analysis of cumulative distribution functions (CDFs) of the “hits” highlighted limits to increased forecast skill beyond temporal and spatial thresholds of 60-min and 100-km. Mean error (ME) plots computed for surface features as well as vertical profiles in pre-convective environments highlighted biases in both the initial conditions as well as between ensembles. In agreement with previous studies, it was found that non-local mixing PBL schemes tend to produce PBLs that are too shallow, cool, and moist while local mixing schemes tend to be deeper, warmer, and drier as a function of the stronger (weaker) vertical mixing within the local (non-local) PBL schemes. Relative to the analysis of the vertical profiles, it was seen that the model has an inherent inability to accurately represent strong capping inversions in models across all PBL schemes suggesting an issue with the handling of vertical diffusion within the PBL and the implicit damping associated with the discretization schemes used within WRF
