Determination of transfer function of COPE correlation interferometer instrument
The comparison of theoretical and instrument response functions and its use as a procedure for determining the transfer function of the COPE correlation interferometer are summarized. Data show qualitative agreement can be obtained when discrepancies between theory and instrument are investigated and instrument components are analyzed in detail. Data were obtained using a set of calibration data and computer algorithms
âActs of Pure Evilâ: The Portrayal of Mass Shooting Events on Online Media Platforms
As media continues to integrate into everyday life, it is essential to critically examine the media and the messages that are forwarded to the public, who often lack personal knowledge of crime and justice issues, and thus rely on news media to glean information. This effort, also called media criminology, seeks to understand the media and the effect it has on understanding societal issues. This project forwards media criminology by examining online news articles, as media criminology has historically focused on traditional media formats, such as newspaper and television. Online news has surpassed these traditional formats and has become a main source of information, however, information in online news articles can often include opinions alongside facts. As such, this project utilizes a conflict criminology framework to analyze the messages used in the media to achieve hegemony. In order to fully grasp how the media forwards messages about crime and justice issues, eight mass shooting cases were chosen to discover what differences, if any, are present in the representation of mass shooting events across liberal and conservative mainstream news sites and news commentary sites. News sites were chosen based on their comparable consumer traffic and their political orientation as conservative or liberal. Mainstream news sites are those national news sites that are popular and considered reliable sources of information. The two mainstream news sites chosen for this project are NBC News and Fox News. Commentary sites are sites that feature information alongside opinion, and often engage in partisan reporting. The two news commentary sites chosen for analysis are Slate and Breitbart. Once cases and news sites were chosen, a word frequency query was performed on all articles, followed by thematic analysis for the portrayal of offenders and victims, as well as how cases were explained and what policies were forwarded. Results reveal that media bias does exist along political party lines of the news media when representing mass shooting cases. Offenders and victims alike were subjected to sympathetic and unsympathetic themes. Additionally, the explanations and subsequent policy discussions that were forwarded often aligned with the shootersâ motives, but also with the narratives that fit the news siteâs political orientation
The determination of atmospheric trace gases using the correlation interferometer technique
The theoretical feasibility inherent in the correlation interferometry technique is demonstrated. High signal to noise and increased information content in a given partial interferogram are attractive features of the technique. The separation of interfering gas species is overcome by a precise measurement program for spectral line parameters of methane and other species. There are optical, mechanical, and electronic difficulties with the interferometry hardware design. Flight data from Cessna 402 over southeastern Virginia during April 1978 yielded amplitude fluctuations that are explainable only as internal nonlinearities. Misalignment of the AGC/interferometer optical axis also contributed to a large error source in the flight data. It is concluded that no useful data on gas burdens was obtained from these flights
A Causal-Comparative Study of the Flipped Classroom: A Blended Learning Approach to Improving Phonemic Awareness for Kindergarten English Language Learners
The purpose of this study was to explore the effectiveness of using the flipped classroom model of instruction to increase English language learnersâ phonemic awareness compared to English language learners who received instruction using the business-as-usual approach. This quantitative perspective used a causal-comparative approach to measure achievement in developing phonemic awareness for students at risk due to lack of exposure to English language phonemes. The study involved 167 participants who underwent a pre-test to address any initial group differences. One group received flipped model instruction with curriculum-based video lessons, while the other received traditional in-class expository instruction without access to video lessons. Pre-test and post-test assessments from the Measure of Academic Progress (MAP) were utilized to gauge students\u27 phonemic awareness progress. After four weeks, the researcher collected data, which was then analyzed using a two-way analysis of covariance (ANCOVA) to determine the impact of flipped instruction on phonemic awareness development. The results of the ANCOVA indicated a statistically significant difference in post-test scores, with students in the traditional instruction group outperforming those in the treatment group. No significant gender-based differences were observed, but a significant interaction emerged when considering setting and gender together. This research contributes to the body of knowledge concerning the effectiveness of flipped classroom instruction and its impact on academic achievement, particularly for English language learners. Future research recommendations include extended learner training, a year-long study, and the development of a modified flipped model tailored to younger learners
Migrant or Menace: Media Representations of the Migrant Caravan
In March 2018, the Pueblo Sin Fronteras migrant caravan began making their way to the U.S. border, drawing political and media attention from the United States. News coverage of immigrants and migration events have historically been linked to negative topics and framed as threats to the American way of life. These negative themes emerged against the backdrop of the Trump administrationâs response to the caravan, describing migrants as threats to U.S. border security. To examine how the news media portrayed this event, we conducted a summative content analysis of online news articles from CNN and Fox News covering the 2018 Pueblo Sin Fronteras migrant caravan to determine whether variation exists in the representation of the migrant caravan between liberal and conservative mainstream media outlets. Our study reveals that both CNN and Fox participated in agenda setting by framing migrants and the migrant caravan in ways they saw fit.https://digitalcommons.odu.edu/gradposters2021_artsletters/1003/thumbnail.jp
INTELLECTUAL FUNCTIONS OF PATIENTS WITH CHILDHOOD-ONSET EPILEPSY
The intellectual functions of 64 epileptic patients who had had an initial evaluation between five and 16 years of age, including the WISC, were re-evaluated after a period of at least five years. In general the seizure states had improved, and 50 per cent were in remission for between two and eight years. All but four were still taking at least one anticonvulsant drug. WISC IQ estimates showed a slight decrease. Verbal and performance areas could be differentially affected, and a gain in one could be offset by a loss in the other, so the Full-scale IQ might not be a reliable measure of day-to-day performance. Those whose seizures remained uncontrolled had a statistically significant decrease in performance IQ, whereas in general it was stable or increased for patients in remission. There was evidence that decreased IQ indicated slower mental growth rather than loss of previously acquired function. Phenobarbital but not phenytoin levels were inversely correlated with IQ, suggesting that the upper limit of the âtherapeutic rangeâ of phenobarbital may already be toxic with regard to learning abilities. To optimize an epileptic child's functioning in school and to prevent long-term intellectual problems, it is advisable that IQ testing should be part of the routine initial evaluation, and that drug levels should be checked at regular intervals. RĂSUMĂ Les fonctions intellectuelles de 64 Ăpileptiques dont I'intelligence avait ĂtĂĂvaluĂe entre cinq et 16 ans, notamment par le WISC, ont ĂtĂ remesurĂes aprĂs une pĂriode d'au moins cinq ans. En gĂnĂral IâĂtat des crises sâĂtait amĂliorĂ et 50 pour cent des sujets Ătaient en rĂmission pour des pĂriodes allant de deux Ă huit ans. Tous les sujets sauf quatre prenaient encore une mĂdication anticomitiale. Les QI au WISC montraient une lĂgĂre perte. Les Ăchelles verbale et performance pouvaient Ătre modifiĂes de faĂon diffĂrente et un gain dans l'une des Ăchelles pouvait Ătre compensĂ par une perte dans I'autre, si bien que la pleine Ăchelle de QI pourrait ne pas Ătre une mesure fiable des performances journaliĂres. Les sujets dont les crises demeuraient non contrĂlĂes prĂsentaient une baisse statistiquement significative Ă lâĂchelle de performance, alors que cette Ăchelle Ătait en gĂnĂral stable ou en gain pour les sujets en rĂmission. Des signes indiquaient que la baisse de QI Ătait davantage liĂe Ă un ralentissement de la croissance mentale quâĂ une perte des fonctions antĂrieurement acquises. Les taux de phĂnobarbital mais non de phĂnytoine Ătaient inversement corrĂlĂs au QI, suggĂrant que la limite supĂrieure de âlâĂtendue thĂrapeutiqueâ du phĂnobarbital peut dĂjĂĂtre toxique en ce qui concerne les aptitudes d'apprentissage. Pour optimiser I'activitĂ scolaire d'un enfant Ăpileptique et pour prĂvenir des problĂmes intellectuels Ă long terme, il est souhaitable que des mesures de QI fassent partie des Ăvaluations initiales de routine et que les taux de mĂdication soient contrĂlĂs Ă intervalles rĂguliers. ZUSAMMENFASSUNG 64 Patienten mit Epilepsie, die zwischen fĂnf und 16 Jahren erstmals untersucht und beurteiltâ einschlieĂlich WISCâworden waren, wurden nach mindestens fĂnf Jahren nachuntersucht. Im allgemeinen hatte sich das Anfallsleiden gebessert und 50 Prozent waren seit zwei bis acht Jahren in der Remission. Alle, auĂer vier Patienten, nahmen noch mindestens ein Antikonvulsivum. WISC IQ-SchĂtzungen zeigten eine leichte Verschlechterung. Verbale-und Leistungs- Bereiche konnten unterschiedlich betroffen sein und eine Verbesserung in einem Bereich konnte durch eine Verschlechterung in dem anderen relativiert werden, so ist der Gesamt-IQ nicht unbedingt ein verlĂĂliches MaĂ fĂr die tĂgliche Leistung. Die Patienten mit unkontrolliertem Anfallsleiden zeigten eine statistisch signifikante Verschlechterung des Leistungs-IQ, wĂhrend er bei Patienten in der Remission im allgemeinen stabil war oder besser wurde. Es fanden sich Hinweise dafĂr, daĂ ein abfallender IQ eine verlangsamte geistige Entwicklung anzeigte und nicht einen Verlust von zuvor erworbenen Funktionen. Phenobarbital, jedoch nicht Phenytoinspiegel korrelierten umgekehrt mit dem IQ, was vermuten lĂĂt, daĂ der obere therapeutische Bereich von Phenobarbital schon im Hinblick auf die LernfĂhigkeit toxisch sein kann. Um die Schulleistungen eines Kindes mit Epilepsie zu verbessern und um spĂtere intellektuelle Probleme zu vermeiden, ist es ratsam, IQ-Testungen als Teil der routinemĂĂigen Erstbeurteilung durchzufĂhren und in regelmĂĂigen AbstĂnden Medikamentenspiegel zu kontrollieren. RESUMEN Las funciones intelectuales de 64 pacientes epilĂpticos que habian pasado una primera evaluaciĂn entre los cinco y los 16 aĂos de edad, incluyendo el WISC, fueron reevaluados despuĂs de un periodo de al menos cinco aĂos. En general la incidencia de ataques habĂa mejorado y el 50 por ciento se hallaban en remisiĂn de dos a ocho aĂos. Todos excepto cuatro tomaban todavia un fĂrmaco anticomicial El CI en el WISC mostraba un ligero descenso. Las Ăreas verbales y de manipulaciĂn podĂan afectase diferentemente, de forma que la mejorĂa en un campo podĂa ser desvirtuada por un descenso en el otro, por lo que la escala global de CI podĂa no ser una mediciĂn fidedigna de la realizaciĂn dia a dia. Aquellos cuyas convulsiones permanecĂan sin control tenĂan una disminuciĂn estadisticamente significativa en el CI manipulativo, mientras que en general permanecĂa estable o aumentaba en los pacientes en remisiĂn. Esto evidencia que el descenso en el CI indicaba un crecimiento mental mĂs lento, mĂs bien que una pĂrdida de una funciĂn previamente conseguida. Los niveles de fenobarbital, pero no los de fenitoina, estaban en correlaciĂn inversa con el CI, lo que sugiere que el lĂmite superior del margen terapĂutico del fenobarbital puede ya ser tĂxico con respecto a las capacidades de aprendizaje. Para optimizar el que un niĂo epilĂptico vaya bien en la escuela y para prevenir problemas intelectuales a largo plazo, se aconseja que la mediciĂn del CI forme parte de la rutina de exploraciĂn inicial y que la determinaciĂn de los nivele < refs en sangre de los fĂrmacos se haga a intervalos regulares.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65523/1/j.1469-8749.1986.tb03826.x.pd
Panel. Current Research on Slavery at the University of Mississippi
The March Toward Militancy: Student Aggression and the Slave Community at the University of Mississippi / Chet Bush, University of MississippiThe first thirteen years of the University of Mississippi offer a window through which to observe the activities that characterized the all-male student culture. While community storytellers have imagined a single meeting where students hatched a plan to form a military company in support of the Confederacy, the archives of the university suggest a much longer gestation of violence and militancy. From the founding of the university in 1848 to the start of the war in 1861 students demonstrated an increasingly obsessive preoccupation with asserting authority. Student concern for displaying power grew particularly hostile toward the slave community in the years leading up to the Civil War. This paper charts the march toward militancy that students expressed, chiefly toward enslaved workers, during the first thirteen years of the University of Mississippi.Proslavery and Statesâ Rights Incubators: Fraternal Debate Societies at the University of Mississippi, 1848-1861 / Andrew Marion, University of MississippiThis presentation will examine how two fraternal debate societies at the University of Mississippi worked as incubators for proslavery and states\u27 rights ideology for the students from 1848 to 1861. Mandatory participation in these societies put students in academic environments that promoted unwavering loyalty to the state of Mississippi and its most sacred institution, slavery. An examination of proslavery rhetoric delivered at the university and debate society meeting minutes and publications will help explain the incredible commitment that the University of Mississippi\u27s students made to defend slavery and the Confederacy.The World the Slaves Made: Slaveholding, Student Wealth, and the Foundations of the University of Mississippi / Anne TwittyWhen fifteen-year-old John Sanders McRaven of Marshall County matriculated at the University of Mississippi in 1849, his father, planter Robert McRaven, was no doubt the animating force. If Robert was the architect of Johnâs education, however, the sixty-one men, women, and children Robert claimed in the 1850 census were its underwriters. Although scholars have identified many enslaved people who lived on college campuses and examined the centrality of their work at such facilities, little attention has been paid to the enslaved people laboring tens or hundreds of miles from these institutions who nevertheless helped create, facilitate, and maintain them. To address this omission, this paper traces the slaveholdings of the University of Mississippiâs first students through the 1850 census to explore how enslaved black people far removed from the University of Mississippi made possible the scholarly endeavors of free white men at its campus in Oxford
ATMOS Spacelab 1 science investigation
Existing infrared spectra from high speed interferometer balloon flights were analyzed and experimental analysis techniques applicable to similar data from the ATMOS experiment (Spacelab 3) were investigated. Specific techniques under investigation included line-by-line simulation of the spectra to aid in the identification of absorbing gases, simultaneous retrieval of pressure and temperature profiles using carefully chosen pairs of CO2 absorption lines, and the use of these pressures and temperatures in the retrieval of gas concentration profiles for many absorbing species. A search for a new absorption features was also carried out, and special attention was given to identification of absorbing gases in spectral bandpass regions to be measured by the halogen occultation experiment
