The analysis of reverse tandem running of Temnothorax rugatulus colonies

Collective decision making in social organism societies involves a large network of communication systems. Studying the processes behind the transmission of information allows for greater understanding of the decision making capabilities of a group. For Temnothorax rugatulus colonies, information is commonly spread in the form of tandem running, a linear recruitment pattern where a leading ant uses a short-ranged pheromone to direct a following ant to a target location (in tandem).The observed phenomenon of reverse tandem running (RTR), where a follower is lead from a target back to the home nest, has not been as extensively studied as forward tandem running and transportation recruitment activities. This study seeks to explain a potential reason for the presence of the RTR behavior; more specifically, the study explores the idea that reverse tandem run followers are being shown a specific route to the home nest by a highly experienced and efficient leading ant. Ten colonies had migrations induced experimentally in order to generate some reverse tandem running activity. Once an RTR has been observed, the follower and leader were studied for behavior and their pathways were analyzed. It was seen that while RTR paths were quite efficient (1.4x a straight line distance), followers did not experience a statistically significant improvement in their pathways between the home and target nests (based on total distance traveled) when compared to similar non-RTR ants. Further, RTR leading ants were no more efficient than other non-RTR ants. It was observed that some followers began recruiting after completion of an RTR, but the number than changed their behavior was not significant. Thus, the results of this experiment cannot conclusively show that RTR followers are utilizing reverse tandem runs to improve their routes between the home and target nests.

Climate Change and Migration in Papua New Guinea

Climate change is a global phenomenon that is disproportionately impacting people in developing countries. One coping mechanism that has been observed in response to climate change is migration. This paper attempts to understand the role of climate change as a driver of migration in Papua New Guinea, a complex and under-researched country in Oceania. Past research suggests a complicated story, and that migration in response to climate change is not a simple concept. In order add to the existing literature, a variety of individual, household, and community-level variables are analyzed from a survey of households in rural Papua New Guinea. These variables are analyzed in conjunction with self-reported environmental shocks to determine the impact on migration across time. The results suggest that environmental shocks increase the probability of an individual migrating, with various socioeconomic factors acting as push and pull factors.

Migration is natural, a human right, and to some extent, it is seen, allowed, and digested but by what bodies? Whose bodies? Who is given the privilege of range of motion, and who is chained to a ground, underground, buried?
Through a questioning of migration, a mechanism of movement, and its criminalization from the states through the establishment of citizenry, I aim to declare autonomy, and seek a dissection of what it means to criminalize, to establish, render a community as other.

Hasta mañana is a prayer to my parents’ bodies,
to bodies crossing the border,
to bodies displaced,
to bodies that never made it,
to bodies dug up,
buried,
Chained,
Hurting,
Aging,
to bodies I feel and see.

The Migration Framework and Simulator is a combination of C# framework / library and Unity simulation tool used for studying basic migration patterns across the US. Users interact with the
Unity simulation tool by implementing political policies or adjusting values via sliders, buttons, etc., which will alter the values in the framework. The user can then use the simulation interface to view different estimated population values for categories of people, such as regional differences, education levels, and more.

Refugee Clinical Care and Inclusion Infrastructure: Following the journey of Syrian refugees to comprehensively evaluate global care

Description

Human rights and migration policy leave no person in a nation unaffected. Due to the recent Syrian refugee crisis, the world stage has been critically put to the test for its border policies and the infrastructure it can provide for refugees. It is an imperative to reflect on the successes and shortcomings of this ongoing issue in order to build more sustainable and impactful infrastructure for future migrant resettlement. This paper analyzes Sweden, Germany, and Jordan through a lens focused on government and social development and the correlating impact on Syrian refugees. By evaluating government entities and non-government organizations, while also interviewing Syrian refugees themselves, this paper builds a framework for understanding the global stage’s response to the Syrian refugee crisis. Out of this framework are recommendations for more effective resettlement practices, developed via retrospective analysis.

Mental Health in the Undocuqueer Community

Trauma is increasingly experienced by people in transit as border militarization increases migrants’ exposure to violence and forces them into more precarious situations. For queer migrants, this includes situations where they are more likely to experience persecution and sexual violence. This paper explores the availability of care for queer undocumented migrants in the United States after surviving a precarious and potentially deadly journey from their country of origin to the US, as well as forms of alternative care developed by the undocuqueer community. In particular, it focuses on access to care for LGBT migrants, who face stigmatization on multiple levels and as a result are more likely than their straight counterparts to experience extreme mental health consequences pre-, in-, and post-transit. Faced with a number of obstacles that prevent them from receiving appropriate mental health care, the undocuqueer community utilizes various strategies to ensure that the health and needs of the community are supported. I argue that in spite of facing traumatic experiences and being unable to fully access healthcare to alleviate these problems in the US, LGBT migrants demonstrate extreme resilience and resist the mechanisms that otherwise threaten their mental well-being.

Bhairavi: A Performance-Investigation of Belonging and Dis-Belonging in Diaspora Communities

Bhairavi is a solo performance that investigates belonging and dis-belonging in diaspora communities, especially as it relates to the female body. Specifically, through my experience as a second-generation Indian-American woman - I expose and challenge the notion of ‘tradition,’ as it is forced into women’s bodies, and displaces them in their own homes. Bhairavi is a story told through movement and theatrical narrative composition with research and material collected through structured and unstructured observation of my family, cultural community, and myself.

Note: This work of creative scholarship is rooted in collaboration between three female artist-scholars: Carly Bates, Raji Ganesan, and Allyson Yoder. Working from a common intersectional, feminist framework, we served as artistic co-directors of each other’s solo pieces and co-producers of Negotiations, in which we share these pieces in relationship to each other. Thus, Negotiations is not a showcase of three individual works, but rather a conversation among three voices. As collaborators, we have been uncompromising in the pursuit of our own unique inquiries and voices, and each of our works of creative scholarship stand alone. However, we believe that all of the parts are best understood in relationship to each other, and to the whole. For this reason, we have chosen to cross-reference our thesis documents.

Language as a Barrier to the Eurozone Being an Optimum Currency Area

Description

The European Union has increasingly integrated since World War II to the point where most European countries now share a currency and have freedom of movement for travelers and workers.

The European Union has increasingly integrated since World War II to the point where most European countries now share a currency and have freedom of movement for travelers and workers. This has created asymmetries in the European economy because of reports and studies that have found a low labor mobility, which is a requirement of a common currency area. This paper uses an econometric model and the theory of optimum currency areas to look at whether what language grouping a migrant is from affects his or her migration decision. The paper also looks at what an inflexible labor market may mean for European Central Bank policymakers and the macroeconomic outlook of the eurozone.

The purpose of this study, which was done in conjunction with the Arizona Heart Foundation, was to evaluate whether pyridoxine accelerates ulcer wound healing in diabetic patients with ulcers in the lower extremities. In this study, 100 mg of pyridoxine per day was given to patients in the experimental group (while they receive normal wound treatment) while patients in the control group received normal treatment of wounds without the pyridoxine. Over time, wound healing was evaluated by photographing and then measuring the size of patients' ulcer wounds on the photographs. Results from the experimental group were compared with those of the control group to evaluate the efficacy of the pyridoxine treatment. In addition, comparisons of the healing rates were made with respect to whether the patients smoked, had hypertension or hypotension, and the patients' body mass indexes. It has been found that there was no statistically significant difference in the mean healing rates between the control groups and experimental groups. In addition, it has been found that smoking, BMI and blood pressure did not have a statistically appreciable effect on the difference in mean healing rates between the control and experimental groups. This is evidence that pyridoxine did not have a statistically significant effect on wound healing rates.

The Effect of VEGF-ECM Crosstalk on Neural Stem Cell Behavior

The endogenous response of neural stem cell/progenitor (NPSC) recruitment to the brain injury environment following a traumatic brain injury (TBI) is currently under heavy investigation. Mechanisms controlling NPSC proliferation and migration to the brain injury environment remain unclear; however, it is thought that the vascular extracellular matrix proteins (e.g. laminin, fibronectin, and vitronectin) and vascular endothelial growth factor (VEGF) play a role in mediating NPSC behavior through vasophillic interactions. This project attempts to uncover potential VEGF-ECM crosstalk in mediating migration and proliferation. To investigate migration, neurospheres were seeded on ECM-coated wells supplemented with VEGF and without VEGF, and neural outgrowth was measured at days 0, 1, 3, and 8 using differential interference contrast microscopy. Furthermore, single-cell NPSCs were seeded on ECM-coated Transwell membranes with VEGF supplemented media on one side and without VEGF to look at chemotactic migration. Migrated NPSCs were visualized with DAPI nuclear stain and imaged with an inverted fluorescent microscope. To investigate NPSC proliferation, NPSCs were seeded on ECM coated plates as in the radial migration assay and visualized with EdU on day 8. Total proliferation was measured by seeding NPSCs on ECM coated 96-well plates and incubating them with MTT on days 3 and 6. Proliferation was measured using a spectrophotometer at 630nm and 570nm wavelengths. It was found that VEGF-laminin crosstalk synergistically increased radial migration, but may not play a role in chemotactic migration. Understanding the mechanisms behind VEGF-laminin crosstalk in NPSC proliferation and migration may provide crucial information for the design of stem cell transplantation therapies in the future.
