Procedural failures during the expedited removal process

This thesis contributes to our understanding of the impediments to protection faced by asylum seekers subject to the “expedited removal,” or summary deportation, provisions of the Immigration and Nationality Act. By studying various texts, from the statute itself, to agency policy memoranda, to human rights reports, I compare the law of expedited removal as it is written and interpreted by the government, to the law as it is actually applied. I then argue that asylum seekers caught up in the expedited removal process are not being given the procedural protections that they deserve. This topic is of particular interest in light of recent immigration enforcement policy changes ordered by the Trump administration. Specifically, President Trump has extended expedited removal to cover noncitizens with substantial ties to the United States. While many academics have studied immigration enforcement, I hope to add to the conversation by looking deeply at the texts that make up the law of expedited removal, and contrasting the procedures outlined in these texts with de facto procedures in the field. As a future immigration lawyer, I believe that it is important to add to lay understanding of the law of expedited removal, and the impediments to protection that asylum seekers face when they are placed in expedited removal proceedings.Latin American StudiesLa

Velocity-resolved observations of water in Comet Halley

High resolution (lambda/delta lambda approx. = 3 x 10 to the 5th power) near-infrared observations of H2O emission from Comet Halley were acquired at the time of maximum post-perihelion geocentric Doppler shift. The observed widths and absolute positions of the H2O line profiles reveal characteristics of the molecular velocity field in the coma. These results support H2O outflow from a Sun-lit hemisphere or the entire nucleus, but not from a single, narrow jet emanating from the nucleus. The measured pre- and post-perihelion outflow velocities were 0.9 + or - 0.2 and 1.4 + or - 0.2 km/s, respectively. Temporal variations in the kinematic properties of the outflow were inferred from changes in the spectral line shapes. These results are consistent with the release of H2O into the coma from multiple jets

Groupthink and the Classroom: Changing Familiar Patterns to Encourage Critical Thought

Groupthink is an unhealthy decision-making pattern characterized by a high degree of cohesiveness and a striving for consensus among the members of a decision-making group. This article considers the classroom as a potential contributor to the groupthink phenomenon, comparing the antecedent conditions for group think with typical classroom conditions and expectations. With a plausible, though unproven, link between the classroom and group think decision making, four suggestions are offered teachers for encouraging independent thought and action in students. The four suggestions include adding critical-thinking skills, decision-making skills, small group communication skills, and conflict management skills to the curriculum. These additions are possible and valuable at every educational level

Probing the mechanical properties of graphene using a corrugated elastic substrate

The exceptional mechanical properties of graphene have made it attractive for nano-mechanical devices and functional composite materials. Two key aspects of graphene's mechanical behavior are its elastic and adhesive properties. These are generally determined in separate experiments, and it is moreover typically difficult to extract parameters for adhesion. In addition, the mechanical interplay between graphene and other elastic materials has not been well studied. Here, we demonstrate a technique for studying both the elastic and adhesive properties of few-layer graphene (FLG) by placing it on deformable, micro-corrugated substrates. By measuring deformations of the composite graphene-substrate structures, and developing a related linear elasticity theory, we are able to extract information about graphene's bending rigidity, adhesion, critical stress for interlayer sliding, and sample-dependent tension. The results are relevant to graphene-based mechanical and electronic devices, and to the use of graphene in composite, flexible, and strain-engineered materials.Comment: 5 pages, 4 figure

Ohio Principals’ Perceptions of Communication Skills, Factors, and Courses Among Criteria for Secondary- Teacher Effectiveness

In a recent article in Communication Education, Curtis, Winsor, and Stephens (1989) presented the results of a study that assessed managers’ perceptions of the skills and abilities of greatest significance in the business setting. The authors concluded “It is our belief and the belief of perspective (sic) employers throughout the United States that courses such as public speaking, listening, and interpersonal communication should be included as an oral communication core in (business programs)” (p. 13). The present study seeks to expand their findings and beliefs to a secondary-education setting. Specifically, this paper presents the results of a survey study conducted using a sample of secondary principals from the state of Ohio. The primary research question was “What skills, factors, and coursework are considered of greatest importance by secondary principals as administrators involved in the hiring and evaluation of secondary teachers?” A second question was “How do principals rate communication skills and courses when considering teacher effectiveness?” The intent of the authors was to examine the perceptions of secondary principals to determine tentative answers to these questions answers to these questions. Principles were chosen because they play a central role in the teacher-effectiveness discussion. As educational administrators, most are directly involved in applying effectiveness standards to their schools. In addition, this study attempts to provide some empirical support for the assertions and suggestions of Dewitt, et all., (1991) as they argue for an increased role for oral-communication theory and practice in education, and for Allen and Shaw (1990) who assert that communication behaviors are related to teaching effectiveness in the perceptions of supervisors of teachers

Changes in Georgia Restaurant and Bar Smoking Policies From 2006 to 2012

Introduction The purpose of this study is to examine the change in smoking policy status among Georgia restaurants and bars from 2006 to 2012 and to identify restaurant and bar characteristics that are as- sociated with allowing smoking. Methods Data were obtained from similar cross-sectional indoor air sur- veys conducted in 2006 and 2012 in Georgia. Both surveys were designed to gather information about restaurant and bar smoking policies. Weighted χ2 analyses were performed to identify changes in smoking policy status and other variables from 2006 to 2012. Weighted logistic regression analysis was used to test for signific- ant associations between an establishment’s smoking policy and other characteristics. Results The percentage of restaurants and bars in Georgia that allowed smoking nearly doubled, from 9.1% in 2006 to 17.6% in 2012. The analyses also showed a significant increase in the percentage of establishments that allow smoking when minors are present. Having a liquor license was a significant predictor of allowing smoking. Conclusion The Smokefree Air Act was enacted in 2005 to protect the health and welfare of Georgia citizens, but study results suggest that policy makers should reevaluate the law and consider strengthening it to make restaurants and bars 100% smokefree without exemptions

Tracing the Bipolar Outflow from Orion Source I

Using CARMA, we imaged the 87 GHz SiO v=0 J=2-1 line toward Orion-KL with 0.45 arcsec angular resolution. The maps indicate that radio source I drives a bipolar outflow into the surrounding molecular cloud along a NE--SW axis, in agreement with the model of Greenhill et al. (2004). The extended high velocity outflow from Orion-KL appears to be a continuation of this compact outflow. High velocity gas extends farthest along a NW--SE axis, suggesting that the outflow direction changes on time scales of a few hundred years.Comment: 4 pages, 4 figures; accepted for publication in Ap J Letter

Observation of a Snap-Through Instability in Graphene

We examine the competition between adhesive and bending energies for few-layered graphene samples placed on rigid, microscale-corrugated substrates. Using atomic force microscopy, we show that the graphene undergoes a sharp "snap-through" transition as a function of layer thickness, where the material transitions between conforming to the substrate and lying flat on top of the substrate. By utilizing the critical snap-through thickness in an elasticity model for the FLG's bending, we extract a value for graphene-surface adhesion energy that is larger than expected for van der Waals forces.Comment: 8 pages, 3 figure

Venezuelan Equine Encephalitis Virus Transmission and Effect on Pathogenesis

Quantifying the dose of an arbovirus transmitted by mosquitoes is essential for designing pathogenesis studies simulating natural infection of vertebrates. Titration of saliva collected in vitro from infected mosquitoes may not accurately estimate titers transmitted during blood feeding, and infection by needle injection may affect vertebrate pathogenesis. We compared the amount of Venezuelan equine encephalitis virus collected from the saliva of Aedes taeniorhynchus to the amount injected into a mouse during blood feeding. Less virus was transmitted by mosquitoes in vivo (geometric mean 11 PFU) than was found for comparable times of salivation in vitro (mean saliva titer 74 PFU). We also observed slightly lower early and late viremia titers in mice that were needle injected with 8 PFU, which represents the low end of the in vivo transmission range. No differences in survival were detected, regardless of the dose or infection route
