Meteorological, Chemical, And Isotopic Characteristics Of Precipitation Events On The Quelccaya Icecap, Peru: 2014-2016
The Quelccaya Icecap, located in the Cordillera Vilcanota of Southern Peru, is the source of ice cores dating back almost 2,000 years. These are a critical paleoclimatic record for the tropics, where a large part of the world’s population is located. However, the record is complex, and most now believe that the annual layers of the Quelccaya Icecap reveal more about precipitation variability than temperature. The aim of this research is to improve scientific understanding of current precipitation patterns and their effects on the icecap in order to fully resolve this record. A meteorological station installed at 5,650 m in 2014, near the summit of the Icecap, provides meteorological data including snow depth, liquid equivalent precipitation, precipitation type and intensity, and wind speed and direction. NOAA’s HYSPLIT Model was used to run 72-hour backward air trajectories for each precipitation event using GDAS data with half-degree resolution. Isotopic and chemical analysis was performed on the 2016 snowpack yielding stable oxygen isotope ratios and trace element concentrations. The isotopes were used to date the snowpack, and the resulting age model was compared to isotopic measurements from citizen scientists. Trace elements were used make general inferences about regional processes
Sex differences in modes of social influence chosen as a function of attack and motive
This experiment was designed to study the behavior of a naive subject who was placed in a situation where he or she had the task of persuading another person to carry out a simple instruction. Six means of persuasion were made available to the subject. Two of these were physical means of persuasion, giving of pennies and delivery of electric shock. Two of these were verbal, request cooperation and demand cooperation. Two of these were considered to be intermediate between physical and verbal, threat of shock and promise of pennies. The experimental conditions included sex of subject, level of attack, reward contingency, and trials. One specific purpose of the study was to establish the possibility of studying aggression in a persuasion paradigm. The predictions, therefore, were based on results from aggression studies. It was predicted that males would use more electric shock than females, that subjects who were attacked would use more electric shock than subjects who were not attacked, and that subjects who were persuading for a personal monetary reward would shock more than subjects who were persuading to help another person win a monetary reward. It was also predicted that use of all means of persuasion would increase over trials
A study of personal and home living needs of rural high school girls in western North Carolina
Educators are disturbed about the many unmet needs of high school youth. "Among these unmet needs, none is more urgent than the need for sound, practical education for home and family living."1 Education must come at or below the high school level if it is to reach those needing education for family living. The North Carolina Education Commission survey reveals that …approximately one half of those entering high school drop out before graduation. This is especially true in the smaller high schools; 42.4 per cent of students entering 9th grade remain to graduate in 3-4 teacher high schools; About 13 per cent of students go to college.2 High school training for family living is reaching only a small proportion of the students at the present time. Folsom says in regard to education for family living: ". . . we must face the reality that probably not more than 10 per cent of youth now in high school are reached by all existing high school programs combined. ... it is second to no institution in its importance for education in family living."
Managing conflict in multicultural classes : examining the relationship between severity of conflict and the use of interventions by university instructors to manage and resolve conflict
Multicultural class professors are faced with the often difficult task of helping prepare pre-service counselors to meet the mental healthcare needs of an increasingly diverse and pluralistic society. A major factor that has stood in the way of effective training has been students’ resistance to challenging their entrenched patterns of bias and prejudice, which are undermining factors to the process of engendering multicultural awareness, sensitivity, and counseling competency. The purpose of this study was to examine how instructors deal with multicultural classroom conflict in view of the severity of the conflicts they encounter and the techniques and interventions that are used to mediate and resolve conflict arising out of the process of teaching multicultural courses. A total of 122 professors from CACREP affiliated counselor education programs in the U.S. were included in this study with 114 usable sets of participant data. Participants completed a researcher-developed online survey entitled the Multicultural Class Conflict Intervention Survey. A repeated-measures ANOVA and the Friedman Test were conducted to analyze the data. The analysis indicated that the level of challenge experienced by professors in dealing with and resolving multicultural classroom conflict was a statistically significant variable. Limited support was found for the Types of conflict as a predictor of specific patterns of conflict intervention usage when dealing with and resolving multicultural classroom conflict
A comparison between recommendations and practices in interscholastic athletics for junior high schools in North Carolina
The study was undertaken to ascertain the extent to which practices relating to interscholastic athletic programs in the selected schools correlated with recommendations by authorities in the field. An extensive collection of recommendations by authoritative groups and individuals was made and a inquiry form constructed from the consensus of the recommendations. The inquiry form was then mailed out to seventy-four schools meeting the North Carolina State Department of Public Instruction definition of "Junior High School." With the exception of six schools in their first year of operation, this mailing included every school in the state included in the definition. Sixty-four schools, or eighty-six percent, responded to the inquiry form. A compilation of returns seem to indicate that programs of interscholastic athletics generally followed recommendations with some notable exceptions
Experiential education and social justice: philosophical and methodological considerations for integrating experiential learning in educational leadership
Experiential education has been practiced in the United States for the last forty years. During that time, the philosophy and practice has taken a variety of shapes and has evolved in purpose and methodology. Experiential education can be used as a meaningful approach to education often yielding transformational results. This inquiry explores the belief that one aim of education should be to prepare students to become responsible and active citizens within the democratic society they will eventually help to shape. This means offering opportunities for students to engage in meaningful experiences that allow them to grapple with the complexities of social constructs in addition to other intended curricular outcomes. Experiential education is one form of education that can engage students in an active way so they can practice the democratic skills they will use while outside the educational environment.
Using philosophical memoir, I describe the lived experience of experiential education. I explore the aims and promises of experiential education and explore how experiential education is well positioned to be a vehicle for transformational change and how it can be used to address aims of social justice. Experiential education is connected to principles of social justice when it challenges authority hierarchies, when choices are offered during educational experiences and when educators work to create agency within their students, by increasing cultural awareness of self and others through shared experiences of diverse learners. Further, educators would be well served to intentionally utilize experiential methods in order to create truly democratic educational environments that critically examine various issues of equity and justice. Educators and students alike are socially constructed beings that co-create knowledge within experiential classrooms.
Rooted in pragmatic philosophy, I analyze narratives of experience illustrating how knowledge is constructed and how this educational approach can be used for democratic aims. This epistemology set the stage for philosophical themes discussed throughout the inquiry, such as understanding knowledge construction in a way that is useful for the lived experience and utilizing democracy as a way of life. These pragmatist ideas influence and compliment experiential practice encouraging students to examine cultural contexts and practice skills needed within society as they experience and then intentionally reflect on those experiences. This work helps educators to seek to fulfill pragmatist's promises of democracy.
Intentionally focusing on social justice as an educational endeavor asks educators to recognize the cultural constructs of all players within the educational scene. These constructs influence self-concept which in turn, influences how we engage with one another in our educational endeavors. Negotiating principles of social justice means examining institutions for power, privilege and hidden curriculum that may be oppressive or sending messages to students about their worth. It also means nurturing the voices of all learners encouraging them to become agents of change within their personal and social worlds in order to work toward more equitable and just social environments.
The idea is not that experiential education should be used at all times or that it offers a panacea for educational woes. It would be counterproductive and the antithesis of what this inquiry is suggesting to dogmatically prescribe a particular practice. However, just as pragmatists hope for the promise of the democratic experiment, there is hope for experiential praxis to make transformational change toward a more socially just world
An interpretative essay concerning six works of art
The exhibited thesis paintings are intended to communicate a maximum amount of information to the viewer as quickly as possible and then hold his attention. I hope to achieve this immediacy in the design by first organizing simplified analogous shapes placed side by side that later may evolve into an underlying and disguised, large scale rhythmical pattern. However, to hold the viewer's attention involves the intrinsically difficult problem of establishing a balance between variety and unity. The variety may be represented in the manipulation of the full range of elements that exists, including simulated texture, hieractic values, chorded hues, as well as the geometric patterning. Color unity is established by Munsell and Ostwall's color systems, but the harmoniously exact proportioning of shapes is formulated by the studies of Maitland Graves, Gunnar Goude, and Inga Hjortzberg. In the design, then, geometric and algebraic computations are a means of establishing the placement of positive and negative shapes along with the aesthetically "felt" judgement. Written data is frequently left on the painting surface, in the actual problem-solving venture, creating a subtle, elaborate, and enriched surface on a small scale
Alkane Distribution And Chemotaxonomy Of Tree Ferns (Cyatheaceae)
A gas chromatographic study was made of the total n-alkane content of several species of Central American tree ferns (Cyatheaceae). Some species of commonly occuring North American ferns were also studied for comparison. The species studied exhibited the expected n-alkane distribution pattern. Attempted taxonomic correlations had very limited success. The possible existence of a comprehensive taxonomic classification utilizing n-alkanes should be studied more fully when larger samples are available
Variations in recombination rates across Escherichia coli populations
The accumulation of bacterial genomic datasets has created a nuanced and difficult challenge for computational analyses. Based on the current trend of genomes being sequenced, it appears that it won’t be possible to infer complex parameters such as recombination rates for these entire genomic datasets. We assessed the impact different sampling strategies had on recombination rate estimates, along with the impact of gene content and population structure on recombination rate estimates. Overall, we found that while our novel framework yielded consistent estimates of recombination rates, our sampling strategies, population structure, and gene content did not significantly impact recombination rate estimates
