Man, Nature, and New Ideas: The Legacy of Sea Pines Plantation

My goal is to learn the history of Hilton Head Island and logically reason out the way it grew, marking Sea Pine’s design influence over time and place. This paper is meant to be a piece of nature and history writing, which has implications for the study of environmental economics and real-estate design practices, but is not strictly about either. The thrust of this piece is the mapping of developmental philosophies and their reflection in the land. This topic interests me because at its core, it looks at how decisions are made, and the trade offs that influence them. The paper is also about the formation of ideas that explore sustainable forms of human-environment interaction, but which do not give up the high quality of life that modern man has come to expect. Environmental issues will continue to influence social, economic and political thought as we move towards midcentury. Sea Pines champions a blending of man and nature that may be able to provide alternative and more efficient solutions to the problems that our society faces

Life History of a Dune-Dwelling Rhaphidophorid, Utabaenetes Tinkham, in the San Rafael Desert of Utah

The camel cricket, Utabaenetes(tanneri Tinkham, has been little studied. This study gathered information on the basic life history and behavior of this species, which is found only in the San Rafael Desert and adjacent Colorado Plateau in areas of loose sand or active dunes. The daily activity pattern is matutinal, and individuals construct burrows for shelter in the afternoon. The diet of U.(tanneri is omnivorous, composed of plant material, detritus, and conspecific crickets. Utabaenetes(tanneri has been found in the diet of several predatory species, although the total number of observed predation instances is low. Utabaenetes(tanneri might be a Batesian mimic of sympatric tenebrionid beetles, which might explain the small number of observed predation attempts on this species. Utabaenetes(tanneri can be very abundant where it occurs. Abundance and density of crickets was determined for three study plots in Grafield County, Utah. Plot 1 had a mean abundance of 482 crickets, determined by mark and resight analyses, and a mean density of 0.23 individuals per square meter. Only one cricket was found in Plot 2, and no mark and resight analysis was performed. Plot 3 had a mean abundance of 50 crickets, and a mean density of 0.022 individuals per square meter. The bulk density of the soil was compared between the three sites, but no significant difference was found (Kruskal0Wallace X2 = 0.932, df = 2, P = 0.627), and therefore is probably not the reason for the differences in abundances between the three plots. Studies on similar species of sand treaders have indicated that they are important detritivores within arid ecosystems. They are also preyed on by numerous species, and are usually one of the most abundant arthropods where they occur. Utabaenetes(tanneri probably functions in a similar ecological role to these other species of sand treaders. In addition to these observations of U.(tanneri, a morphological description of the species is provided. The first key to the subfamilies of Rhaphidophoridae in the United States and Canada is presented, along with a key to the genera of the subfamily Ceuthophilinae

The Influence of Race/Ethnicity, Gender, Age, Social Support, Religion/Spirituality, and Occupational History on the Total Wellness of Counseling Practicum Graduate Students: A Pilot Study

This study sought to identify and explore the differences in participants’ Total Wellness scores with respect to race/ethnicity, gender, age, social support, spirituality, and occupational history. It was asserted that there would be observable differences in the delineated demographic research factors and that these differences would influence students’ Total Wellness as measured by the 5F-Wel Inventory. The sample was comprised of 30 graduate students enrolled in a community mental health counseling program. Hierarchal linear regression indicated that demographic variables did not predict a change in Total Wellness when controlling for pretest scores; however, pretest Total Wellness scores were significantly predictive of post-test Total Wellness scores. Implications for counseling practice and clinical supervision, suggestions for integrating wellness into counseling education, as well as areas for future research including replication and expansion of the current study are offered

Perceived Stress and Self-Care in Graduate Students Amidst the COVID-19 Pandemic

Introduction: This study examines the perceived stress and self-care behaviors of graduate students as impacted by the COVID-19 pandemic. Students who participated had varying degree concentrations, with the majority of participants having a Clinical Mental Health Counseling, Couples and Family Therapy, Dance Movement Therapy, or Clinical Psychology focus. This study is particularly relevant to health care workers, especially those whose focus is mental health. Markedly elevated prevalence of reported adverse mental and behavioral health conditions associated with the COVID-19 pandemic highlight the broad impact of the pandemic and the need to prevent and treat these conditions. This study sought to examine the presence and significance of a relationship between perceived stress, self-care strategies, and participant characteristics and the impact of COVID-19. Methods: Utilizing a quantitative approach, data were collected via survey method using related questionnaires and assessments; approximately 700 surveys were disseminated to the student-body, with a response rate of 24% yielding 170 initial participants. Pearson bivariate and multiple regression were used to determine the statistical significance of any potential relationship as posed by the research questions. Results: A statistically significant relationship was found between perceived stress and the impact of COVID-19 for the students. Also, using multiple regression, age (p = .005) and race/ethnic identity (p = .006) contributed to the reported levels of perceived stress. Racial identity was a significant predictor of the reported scores on the impact of COVID-19 (p = .01). There was also a significant relationship (p \u3c.001) between adequate sleep and eating nutritiously (p = .016) and reported perceived stress and the impact of COVID-19. Lastly, engaging in social activism was related to an increased impact of COVID-19 (p=.037), specifically for the subscale of hyperarousal (p=.016). Conclusion: A summary of our findings indicates a significant relationship between participant’s perceived stress and the impact of COVID-19; specifically, as the level of perceived stress increased for our participants, so did the impact of the COVID-19 pandemic. Seemingly, those who experience greater daily stress in their lives reported a more significant impact of COVID-19 on their daily lives. These results point to the need for wellness strategies specific to stress reduction strategies to also help in alleviating the distress associated with COVID-19. As universities transition to online learning, online accessible interventions aimed at helping students address stress, depression, and wellbeing, may prove beneficial

Performance of chemically modified reduced graphene oxide (CMrGO) in electrodynamic dust shield (EDS) applications

Electrodynamic Dust Shield (EDS) technology is a dust mitigation strategy that is commonly studied for applications such as photovoltaics or thermal radiators where soiling of the surfaces can reduce performance. The goal of the current work was to test the performance of a patterned nanocomposite EDS system produced through spray-coating and melt infiltration of chemically modified reduced graphene oxide (CMrGO) traces with thermoplastic high-density polyethylene (HDPE). The EDS performance was tested for a dusting of lunar regolith simulant under high vacuum conditions (~10-6 Torr) using both 2-phase and 3-phase configurations. Uncapped (bare) devices showed efficient dust removal at moderate voltages (1000 V) for both 2-phase and 3-phase designs, but the performance of the devices degraded after several sequential tests due to erosion of the traces caused by electric discharges. Further tests carried out while illuminating the dust surface with a UV excimer lamp showed that the EDS voltage needed to reach the maximum cleanliness was reduced by almost 50% for the 2-phase devices (500 V minimum for rough and 1000 V for smooth), while the 3-phase devices were unaffected by the application of UV. Capping the CMrGO traces with low-density polyethylene (LDPE) eliminated breakdown of the materials and device degradation, but larger voltages (3000 V) coupled with UV illumination were required to remove the grains from the capped devices.Comment: 22 pages, 7 figure

Principles, calibration, and process experience for a new laser aerosol detector system

A new type of laser particulate detection instrument has proved extremely valuable in the design and monitoring of oil removal systems for cryogenic refrigeration systems. When located at the inlet of a refrigerator, any aerosol or particulates that could be harmful to the operation of the refrigerator would be detected. Its main features include: in situ measurement of particulates in the high pressure helium continuous monitoring with alarm capabilities which permits automatic shutdown of attended or unattended systems, sensitivity down to a few parts per billion, long-term stability on the order of 10 ppB, and straightforward data interpretation. The concept of continuous automatic calibration and baseline zero adjustment relieves the operator of any manual adjustments or loss of confidence in the signal levels recorded. The 1-second response time allows instant turnoff if the filters experience an oil breakthrough or if an operator inadvertently opens bypass valves around the oil removal system. The stripchart recording allows for long-term comparison of particulate levels to determine if a buildup is occurring and its rate of buildup. It will also aid in predicting the amount of contaminants frozen out in the refrigerator and the operating time remaining before refrigerator shutdown and warmup is required. 8 figures

Scanning probe metrology in the presence of surface charge

Surface charge on insulating samples can be a significant source of error for scanning probe microscopes. We have found that it is possible to operate a scanning force microscope in a manner that makes it relatively immune to charge-induced forces while still allowing the probe tip to nondestructively follow the surface topography. The need to maintain close charge balance on the sample is thus obviated. We have used this strategy to perform critical dimension measurements on optical photomasks with the Surface/Interface Stylus NanoProfilometer. This instrument incorporates a servoed force-balance sensor. Surface topography is determined by touching the surface with contact forces between 0.1 and 1 muN. (C) 2000 American Vacuum Society.

Mechanics of the exceptional anuran ear

The anuran ear is frequently used for studying fundamental properties of vertebrate auditory systems. This is due to its unique anatomical features, most prominently the lack of a basilar membrane and the presence of two dedicated acoustic end organs, the basilar papilla and the amphibian papilla. Our current anatomical and functional knowledge implies that three distinct regions can be identified within these two organs. The basilar papilla functions as a single auditory filter. The low-frequency portion of the amphibian papilla is an electrically tuned, tonotopically organized auditory end organ. The high-frequency portion of the amphibian papilla is mechanically tuned and tonotopically organized, and it emits spontaneous otoacoustic emissions. This high-frequency portion of the amphibian papilla shows a remarkable, functional resemblance to the mammalian cochlea
