We have ground to cover for each other : A case study of mentoring across Black sorority alumni in north central West Virginia

Black sororities are much more than their stereotypes of stepping and partying. They are service organizations that have a deep impact on their communities and help shape the identities of their members. These organizations can be seen at Historically Black Colleges and Universities (HBCUs) and Predominately White Institutions (PWIs). Black sororities are different than their traditionally white counterparts because the majority of active time in membership occurs after graduation. This thesis utilizes a case study of Black sororities in North Central West Virginia and West Virginia University. In spaces lacking in diversity and inclusion, Black sororities can serve as a means for women of color to find a sense of belonging and can help shape their identities as women of color. This thesis based on archival data analysis and semi-structured interviews investigates which forms of mentoring are enacted by Black sorority alumni members, and how such types of mentoring help to find that sense of belonging and identity formation for women of color

Understanding Expressive Writing

Expressing trauma, specifically through expressive writing, leads to better health, both physically and psychologically. Specifically, the relationship between expressive writing and higher rates of affective (emotional) word use can be explained by reappraisal, a technique that reduces stress through better understanding. Reappraisal is thus related to resilience, and both are correlated with secure attachment. Secure attachment, in turn, is best folstered by authoritative parenting. Because of this research we predicted that there would be a positive relationship between resilience, language use, and authoritative parenting. In this study, 100 college-aged participants reported perceived parenting style and resilience. We randomly assigned participants to experimental and control groups, participants in the control group were asked to type a detailed account of their day, while the experimental group was prompted to type about a traumatic experience. Participants\u27 responses were then saved, formatted, and analyzed using the Linguistic Inquiry and Word Count (LIWC) computer software program. We did not find t he hypothesized positive relationship between authoritative parenting, resilience, and emotional language, raising questions about the mechanisms by which expressive writing facilitates well-being

Perfect State Transfer in Laplacian Quantum Walk

For a graph $G$ and a related symmetric matrix $M$, the continuous-time quantum walk on $G$ relative to $M$ is defined as the unitary matrix $U(t) = \exp(-itM)$, where $t$ varies over the reals. Perfect state transfer occurs between vertices $u$ and $v$ at time $\tau$ if the $(u,v)$-entry of $U(\tau)$ has unit magnitude. This paper studies quantum walks relative to graph Laplacians. Some main observations include the following closure properties for perfect state transfer: (1) If a $n$-vertex graph has perfect state transfer at time $\tau$ relative to the Laplacian, then so does its complement if $n\tau$ is an integer multiple of $2\pi$. As a corollary, the double cone over any $m$-vertex graph has perfect state transfer relative to the Laplacian if and only if $m \equiv 2 \pmod{4}$. This was previously known for a double cone over a clique (S. Bose, A. Casaccino, S. Mancini, S. Severini, Int. J. Quant. Inf., 7:11, 2009). (2) If a graph $G$ has perfect state transfer at time $\tau$ relative to the normalized Laplacian, then so does the weak product $G \times H$ if for any normalized Laplacian eigenvalues $\lambda$ of $G$ and $\mu$ of $H$, we have $\mu(\lambda-1)\tau$ is an integer multiple of $2\pi$. As a corollary, a weak product of $P_{3}$ with an even clique or an odd cube has perfect state transfer relative to the normalized Laplacian. It was known earlier that a weak product of a circulant with odd integer eigenvalues and an even cube or a Cartesian power of $P_{3}$ has perfect state transfer relative to the adjacency matrix. As for negative results, no path with four vertices or more has antipodal perfect state transfer relative to the normalized Laplacian. This almost matches the state of affairs under the adjacency matrix (C. Godsil, Discrete Math., 312:1, 2011).Comment: 26 pages, 5 figures, 1 tabl

Limestone and Lime for SO\u3csub\u3e2\u3c/sub\u3e and Pollutant Control in the Ohio Valley

The purpose of this conference is to emphasize the importance of limestone resources for controlling SO2 emissions from coal-fired power plants. We have brought together experts from utilities to describe important factors in limestone performance in scrubbers and from the stone industry to describe important factors in limestone and lime production. Conference speakers include also representatives from research institutes, equipment manufacturers, government agencies, and geological surveys

Geologic Map of Kentucky

This map shows the geologic age of rocks and sediments at the surface in Kentucky. Sedimentary rocks, deposited from about 465 to 290 million years ago during the Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian Periods, crop out across the state. The rocks mainly consist of shale, limestone, sandstone, and siltstone. As shown in the cross sections, these surface rocks are underlain by older unexposed rocks of Precambrian, Cambrian, and Ordovician age. Small bodies of igneous rocks were intruded into the state\u27s bedrock about 270 million years ago during the Permian Period. They crop out in Elliott County of northeastern Kentucky, and in Crittenden and Livingston Counties of western Kentucky. Younger unconsolidated sediments were deposited during the Cretaceous, Tertiary, and Quaternary Periods, from about 95 million years ago to the present time. They cover far western Kentucky and occur across the state in stream valleys and, locally, on uplands. The sediments commonly are composed of clay, silt, sand, and gravel. In northern Kentucky, Quaternary sediments include glacial deposits laid down within the last million years during the Ice Age. The present distribution of rocks and sediments at the surface in Kentucky mainly reflects uplift and downwarping of major structural features and subsequent episodes of erosion. Subsidence in the Appalachian Basin and Illinios Basin has preserved younger coal-bearing rocks of Pennsylvanian age in eastern and western Kentucky, respectively. These younger rocks were eroded from the uplifted Cincinnati Arch in central Kentucky, a process that eventually uncovered Ordovician deposits, the oldest exposed rocks in the state. Vertical and lateral movements along faults have displaced strata in parts of Kentucky. Much younger Cretaceous, Tertiary, and Quaternary sediments were deposited in the downwarped Mississippi Embayment of far western Kentucky, a northern extension of the Gulf Coastal Plain

Higher-Order Substrate Recognition of eIF2α by the RNA-Dependent Protein Kinase PKR

SummaryIn response to binding viral double-stranded RNA byproducts within a cell, the RNA-dependent protein kinase PKR phosphorylates the α subunit of the translation initiation factor eIF2 on a regulatory site, Ser51. This triggers the general shutdown of protein synthesis and inhibition of viral propagation. To understand the basis for substrate recognition by and the regulation of PKR, we determined X-ray crystal structures of the catalytic domain of PKR in complex with eIF2α. The structures reveal that eIF2α binds to the C-terminal catalytic lobe while catalytic-domain dimerization is mediated by the N-terminal lobe. In addition to inducing a local unfolding of the Ser51 acceptor site in eIF2α, its mode of binding to PKR affords the Ser51 site full access to the catalytic cleft of PKR. The generality and implications of the structural mechanisms uncovered for PKR to the larger family of four human eIF2α protein kinases are discussed
