What street harassment means

This paper is exploratory research into how college-age women understand their experiences of street harassment. Street harassment is a normative experience for women living in patriarchal cultures, and is an intrusive experience faced regularly in public life. Women told their experiences as part of a narrative that changed over time as they aged from teens into college. Their experiences were not confined to the street, but experienced across public life, and women often carry the weight of harassment in silence. Women resign to the ongoing reality of harassment, and their experiences did not exist in a vacuum but a larger mosaic of gendered violence at the hands of men

Accounting for Impact: A Path to Innovation Through CSR Reporting

Corporate Social Responsibility (CSR) Reporting has emerged as a way for companies to communicate emphasis and measures beyond the traditional profit. CSR Reporting has the potential to be used as a tool for companies to move from just compliance with sustainability standards to promote efficiency and innovation. Through case studies of current users, my project explores three reporting platforms and how these platforms can help companies measure this transition to efficiency and innovation rather than using sustainability practices as window-dressing for the reputation company

This study has resulted in Georgia Now and Forever initiative, an ambitious undertaking to educate key decision-makers across Georgia as to the study's findings with a message that intentional, thoughtful decisions around use of Georgia's remaining undeveloped land are inextricably linked to Georgia's future ecological and economic sustainability. Unsurprisingly, but important to have clearly documented, is the role low density development has played in the significant acreage conversion from agricultural land, forested land, and wetlands. These findings from past development patterns have allowed for the identification of plausible future landcover change trends, assuming business-as-usual development approaches. North Georgia is clearly in the path of major landcover change to low density developed land as metro Atlanta proceeds to "move" northward. This is also an area of significant ecological and carbon assets in the form of our mountain and valley forests, as well as agricultural lands. There is keen community interest in welcoming development-especially diverse and affordable housing choices-but alongside serious advancement in the conservation of the natural landscape. Representatives from the Habersham County, the City of Clarkesville and the property manager of a large conservation tract in the area that includes two riverfront miles of the Soquee River requested assistance from the Georgia Conservancy and Georgia Tech to consider how and where development and conservation can and should occur across their home county of Habersham. There is an understanding among this group that the very conditions that draw new residents to the area-the forests, mountains, streams-are at risk without a concerted effort to include conservation alongside land-efficient development. Given the larger situation in Georgia, the public and political will in the Clarkesville/Habersham area to pursue a larger joint development and conservation priority led to this planning process of identifying strategies for managing local resources in a sustainable way.Habersham CountyCity of Clarksvill

Testing Differences in Vital Lung Capacity Between Long-Term Cigarette Smokers, Vapers, and Non-Smokers

Our research group sampled 15 subjects lungs in a semester-long project. Will there be a significant difference between the lung capacity and lung volume of cigarette smokers, vapers, and non-smokers? It is hypothesized that the lung capacity and lung volume of cigarette smokers and vapers should be relatively equal. Additionally, it is hypothesized that the non-smokers’ lung capacity and lung volume should be significantly higher relative to cigarette smokers and vapers

Effect of an impulsive force on vortices in a rotating Bose-Einstein condensate

The effects of a sudden increase and decrease of the interatomic interaction and harmonic-oscillator trapping potential on vortices in a quasi two-dimensional rotating Bose-Einstein condensate are investigated using the mean-field Gross-Pitaevskii equation. Upon increasing the strength of interaction suddenly the condensate enters a nonstationary oscillating phase which starts to develop more vortices. The opposite happens if the strength is reduced suddenly. Eventually, the number of vortices attains a final value at large times. Similarly, the number of vortices increases (decreases) upon a sudden reduction (augmentation) in the trapping potential. We also study the decay of vortices when the rotation of the condensate is suddenly stopped. Upon a free expansion of a rotating BEC with vortices the radius of the vortex core increases more rapidly than the radius of the condensate. This makes the counting and detection of multiple vortex easier after a free expansion.Comment: RevTeX 4, 7 pages, 7 EPS figure

Spatial Variation of False Map Turtle (Graptemys pseudogeographica) Bacterial Microbiota in the Lower Missouri River, United States

Turtle populations around the world are continually confronted with changing environments that affect their ecology and conservation status. Among freshwater turtles, population dynamics are thought to be mediated by complex yet often cryptic causes. One recent direction of focus in addressing these causes is the turtle-associated microbiota. In turtles, the gut- associated microbiota is of exceptional interest due to its continual association with host species under changing conditions. Diet-based fluctuations and changes in microbial diversity may correspond to varying external environments at both the individual and population level. Environmental responses are of particular interest due to the anthropogenic changes that may underlie them. Pollutants, disruption of climatic patterns, and habitat fragmentation all have the potential to affect turtle-associated microbiota and subsequent population and species conservation. To better understand potential human-induced changes, the diversity of turtle-associated microbiota over local spatial gradients must be better understood. We examined microbial community alpha- and beta-diversity among 30 adult False Map Turtles (Graptemys pseudogeographica) at three sites within the lower Missouri River, United States. Our results indicate significant microbial community centroid differences among sites (beta-diversity), which are likely mediated by various local environmental factors. Such factors will have to be carefully considered in any future attribution of anthropogenic determinants on turtle-associated microbiota as it relates to turtle population dynamics

Dissipative dynamics of vortex arrays in trapped Bose-condensed gases: neutron stars physics on μ\muK scale

We develop a theory of dissipative dynamics of large vortex arrays in trapped Bose-condensed gases. We show that in a static trap the interaction of the vortex array with thermal excitations leads to a non-exponential decay of the vortex structure, and the characteristic lifetime depends on the initial density of vortices. Drawing an analogy with physics of pulsar glitches, we propose an experiment which employs the heating of the thermal cloud in the course of the decay of the vortex array as a tool for a non-destructive study of the vortex dynamics.Comment: 4 pages, revtex; revised versio

Cerebral Vasoreactivity Is Impaired Beyond Symptom Resolution Following Concussion in Collegiate Athletes

Compromised cerebral blood flow (CBF) regulation is linked to impaired functional outcome following concussion. Cerebral vasoreactivity (CVR), an important mechanism in CBF regulation, is the ability of cerebral blood vessels to alter blood flow during dynamic changes in arterial carbon-dioxide (CO₂). PURPOSE: The purpose of this study was to examine CVR in an ongoing prospective cohort of collegiate athletes during acute (day-3) and sub-acute (day-21) phases following concussion and compare them with non-injured athletes. METHODS: Sixteen male and female collegiate athletes (21±1 years) with sports-related concussion and 16 sports matched non-injured controls (21±1 years) were enrolled in the study. For injured athletes, data was collected during the acute and sub-acute phase following concussion and for the controls data was collected at one time point. Symptom severity and cognition were assessed using the Sports Concussion Assessment Tool-3rd Edition. Continuous middle cerebral artery blood flow velocity (MCAV) was obtained with transcranial Doppler ultrasonography (TCD) while subjects were seated in an upright position. End-tidal CO₂ (PetCo₂) was measured with an infrared CO₂ analyzer attached to a nasal cannula. MCAV was evaluated in response to changes in PetCo₂ for 2-minutes each during normal breathing (normocapnia), inspiring a gas mixture containing 8% CO₂, 21% oxygen (hypercapnia) and, hyperventilating (hypocapnia). CVR was analyzed as the slope of the linear relationship between PetCo₂ and MCAV, which was expressed as the percent change in CBF velocity per mmHg change in PetCo₂. Independent and paired t-tests were used to compare symptom severity, and CVR between acute and sub-acute phase following concussion with the controls. RESULTS: As anticipated, concussed athletes exhibited higher symptom severity (26.3±0.5 versus 5±7 P= 0.0007) and lower cognition (26.5±1.6 versus 28.3±2.4 P=0.03) during acute phase compared to the controls. Although symptoms and cognition were resolved during the sub-acute phase, CVR was lower in the acute phase compared to the non-injured controls (1.7±0.5U versus 2.3±0.3U, P=0.0006) and it continued to be blunted in the sub-acute phase following concussion (1.9±0.5U P=0.04). CONCLUSION: Despite improvements in symptom and cognition, cerebral vasoreactivity appears to be impaired in the sub-acute phase following concussion. Cerebral vasoreactivity utilizing TCD may be a useful vascular biomarker for physiological recovery and aid in accurate return-to play decision-making

Targeting HIF-2α in the Tumor Microenvironment: Redefining the Role of HIF-2α for Solid Cancer Therapy.

Inadequate oxygen supply, or hypoxia, is characteristic of the tumor microenvironment and correlates with poor prognosis and therapeutic resistance. Hypoxia leads to the activation of the hypoxia-inducible factor (HIF) signaling pathway and stabilization of the HIF-α subunit, driving tumor progression. The homologous alpha subunits, HIF-1α and HIF-2α, are responsible for mediating the transcription of a multitude of critical proteins that control proliferation, angiogenic signaling, metastasis, and other oncogenic factors, both differentially and sequentially regulating the hypoxic response. Post-translational modifications of HIF play a central role in its behavior as a mediator of transcription, as well as the temporal transition from HIF-1α to HIF-2α that occurs in response to chronic hypoxia. While it is evident that HIF-α is highly dynamic, HIF-2α remains vastly under-considered. HIF-2α can intensify the behaviors of the most aggressive tumors by adapting the cell to oxidative stress, thereby promoting metastasis, tissue remodeling, angiogenesis, and upregulating cancer stem cell factors. The structure, function, hypoxic response, spatiotemporal dynamics, and roles in the progression and persistence of cancer of this HIF-2α molecule and it
