Affinity Seeking in the Writing Center: An Analysis of One-on-One Tutoring Sessions

This study applied the instructional communication concept of affinity seeking to one-on-one peer tutoring sessions. Using content analysis of video recorded tutoring sessions, this study found that tutors most frequently use five affinity seeking strategies: Self Concept Confirmation, Nonverbal Immediacy, Assume Control, Personal Autonomy, and Listening. These strategies differ from those used by teachers and graduate teaching assistants. Differences in tutor affinity-seeking strategies were identified based on gender, especially in sessions with male tutees. Addressing these contextual and gender differences will provide opportunities for improved tutor training and practice

Not Trans Enough: The Intersections of Whiteness \u26 Nonbinary Gender Identity

In this study, I attempt to lay the groundwork for nonbinary gender identity to have space in the growing field of trans studies by looking into how nonbinary identity is affected by intersectional paradigms. Specifically, I look into whiteness as a racial category and how that influences specific identity experiences. Drawing on interview data from both white people and people of color, I examine how whiteness and nonbinary gender identity interact in identity formation and how this affects the lived experiences of my respondents

Impact of Energy Crops on Soil Management and Erosion

Energy crops are perennials that require less cultivation and inputs than conventional crops, and are low maintenance harvest crops used for biofuels

Evaluating Preference and Rate of Gambling on Vedio Slot Machines

Casinos increasingly are providing access to five-reel video slot machines and as a result are decreasing the use of traditional three-reel slot machines. Limited research has been conducted on the characteristics of play associated with video slot machines. The present study examined participant’s play on a five-reel video slot machine, comparing the number of trials played while wagering one credit on five lines versus five credits on one line. After participants were exposed to both conditions they were asked to choose their preferred condition. The results found that participants played significantly more trials while playing during the five credits on one line setting. The results also found that 12 out of 16 participants selected to play on the five lines on one credit setting when given the option to choose the settings of the slot machine

The Structure of a \u3cem\u3eLactobacillus helveticus\u3c/em\u3e Chlorogenic Acid Esterase and the Dynamics of Its Insertion Domain Provide Insights into Substrate Binding

Chlorogenic acid esterases (ChlEs) are a useful class of enzymes that hydrolyze chlorogenic acid (CGA) into caffeic and quinic acid. ChlEs can break down CGA in foods to improve their sensory properties and release caffeic acid in the digestive system to improve the absorption of bioactive compounds. This work presents the structure, molecular dynamics, and biochemical characterization of a ChlE from Lactobacillus helveticus (Lh). Molecular dynamics simulations suggest that substrate access to the active site of LhChlE is modulated by two hairpin loops above the active site. Docking simulations and mutational analysis suggest that two residues within the loops, Gln145 and Lys164, are important for CGA binding. Lys164 provides a slight substrate preference for CGA, whereas Gln145 is required for efficient turnover. This work is the first to examine the dynamics of a bacterial ChlE and provides insights on the substrate binding preference and turnover in this type of enzyme

Acoustic and Microstructural Properties of Partially Molten Samples in the Ice-Ammonia System

We measured the ultrasonic properties and the microstructure of two-phase binary mixtures of the ice-ammonia partial melt system, which was selected based on its importance for numerous planetary bodies. The equilibrium microstructure of ice-ammonia melt was examined using a light microscope within a cold room. The measured median dihedral angle between the solid and melt at 256 K is approximately 63deg, with a broad distribution of observed angles. P-wave velocities in the partially molten samples were measured as a function of temperature and composition. We compare the results of this study to those of other potential binary systems by normalizing the datasets using a vertical lever and articulating the potential effects on the mechanical behavior and transport capabilities of partially molten ice in icy satellites

Advances in Nematode Identification: A Journey from Fundamentals to Evolutionary Aspects

Nematodes are non-segmented roundworms evenly distributed with various habitats ranging to approximately every ecological extremity. These are the least studied organisms despite being the most diversified group. Nematodes are the most critical equilibrium-maintaining factors, having implications on the yield and health of plants as well as well-being of animals. However, taxonomic knowledge about nematodes is scarce. As a result of the lack of precise taxonomic features, nematode taxonomy remains uncertain. Morphology-based identification has proved inefficacious in identifying and exploring the diversity of nematodes, as there are insufficient morphological variations. Different molecular and new evolving methodologies have been employed to augment morphology-based approaches and bypass these difficulties with varying effectiveness. These identification techniques vary from molecular-based targeting DNA or protein-based targeting amino acid sequences to methods for image processing. High-throughput approaches such as next-generation sequencing have also been added to this league. These alternative approaches have helped to classify nematodes and enhanced the base for increased diversity and phylogeny of nematodes, thus helping to formulate increasingly more nematode bases for use as model organisms to study different hot topics about human well-being. Here, we discuss all the methods of nematode identification as an essential shift from classical morphometric studies to the most important modern-day and molecular approaches for their identification. Classification varies from DNA/protein-based methods to the use of new emerging methods. However, the priority of the method relies on the quality, quantity, and availability of nematode resources and down-streaming applications. This paper reviews all currently offered methods for the detection of nematodes and known/unknown and cryptic or sibling species, emphasizing modern-day methods and budding molecular techniques

Brain structural and functional recovery following initiation of combination antiretroviral therapy

NeuroAIDS persists in the era of combination antiretroviral therapies. We describe here the recovery of brain structure and function following 6 months of therapy in a treatment-naive patient presenting with HIV-associated dementia. The patient’s neuropsychological test performance improved and his total brain volume increased by more than 5 %. Neuronal functional connectivity measured by magnetoencephalography changed from a pattern identical to that observed in other HIV-infected individuals to one that was indistinguishable from that of uninfected control subjects. These data suggest that at least some of the effects of HIV on the brain can be fully reversed with treatment

From the Yellow Springs to the Land of Immortality

The Yellow Springs is a vivid metaphorical reference to the final destination of a mortal being and the dwelling place of a departed one in ancient China. In the writings of philosophers, historians, and poets during the long period of Chinese history, the Yellow Springs is not only considered as an underground physical locus where a grave is situated, but also an emotionally charged space invoke grieving, longing, and memory for the departed loved ones. The subterranean dwelling at the Yellow Springs is both a destination for a departed mortal being and an intermediary place to an ideal and imaginative realm, the land of immortality where the soul would enjoy eternity. From the Yellow Springs to the Land of Immortality is an exhibition that highlights sixteen carefully selected artworks from Gettysburg College’s Special Collections; each object embodies the perceptions and ritual practices of the rich funerary culture in the historical period in China, ranging from the late second millennium BCE to the beginning of the early twentieth century. These artifacts represent various artistic traditions and fabrication techniques — including jade carving, bronze casting, glazed pottery making — and most importantly, offer a glimpse of how art and artifacts are employed as a means to connect the living with the soul of the departed one in the Yellow Springs. Archaeo- logical discoveries in the past four decades in China have provided rich information that helps contextualize the sixteen artworks, as well as intimate knowledge about how the objects might “perform” in the life and afterlife of the individuals in the past. The practice of burying goods alongside departed loved ones has had a long tradition in China. The artworks included in this exhibition catalogue, encompassing the major dynasties in Chinese history, epitomize such a practice from a historical point of view. The bronze jue of the Shang dynasty (mid-16th c.-1046 BCE), and the miniature bell, a replica of yong bronze bell of the Zhou dynasty (1045-256 BCE), are not only ceremonial paraphernalia used by elites in ancestral sacrifices during the Bronze Age, but also material manifestations of ritual and music, the very foundations of ancient Chinese civilization. Comparable examples found in Bronze Age tombs illustrate the idea to connect the deceased, often the owner of these ritual objects, to the ancestors in the netherworld as they themselves were transitioned into the role of ancestors through a series of funerary ceremonies.
