We measure new estimates for the galaxy stellar mass function and star formation rates for samples of galaxies at z ∼ 4, 5, 6 and 7 using data in the CANDELS GOODS South field. The deep near-infrared observations allow us to construct the stellar mass function at z ≥ 6 directly for the first time. We estimate stellar masses for our sample by fitting the observed spectral energy distributions with synthetic stellar populations, including nebular line and continuum emission. The observed UV luminosity functions for the samples are consistent with previous observations; however, we find that the observed M_{UV …}

Indigenous European Justice And Other Indigenous Justices, Biko Agozino

African Journal of Criminology and Justice Studies

All human beings are indigenous because everyone originates somewhere and is therefore indigenous there. However, the imperialist reason of Europe refuses to be confined geographically, making global claims to universalism in its knowledge-power axes even while remaining peculiar, especially from the points of view of the rest of us who wonder where to place the emphasis in Eurocentric criminal justice systems. This papyrus will remind us of the old African saying that no palm is big enough to hide the sky and so even the good qualities of European empires of law would never be enough to meet the needs …

Aptian To Santonian Foraminiferal Biostratigraphy And Paleoenvironmental Change In The Sverdrup Basin As Revealed At Glacier Fiord, Axel Heiberg Island, Canadian Arctic Archipelago, Claudia J. Schröder-Adams, Jens O. Herrle, Ashton F. Embry, James W. Haggart, Jennifer M. Galloway, Adam T. Pugh, David M. Harwood

ANDRILL Research and Publications

Exceptional exposures of a High Arctic Cretaceous sedimentary record were studied at Glacier Fiord, Axel Heiberg Island. The succession reveals a complex Aptian to Santonian paleoenvironmental history of the Sverdrup Basin that documents several global events. Foraminiferal faunas in combination with rare macrofossil occurrences permit the distinction of nine zones that facilitate biostratigraphic correlations to other High Arctic locales, the Beaufort Mackenzie Basin and the Western Interior Sea. The depositional environment as exposed in the Christopher, Hassel, Bastion Ridge and Kanguk formations changed frequently from a shelf to a shoreface setting. Most sequence boundaries appear to be conformable where shoaling …

Cubic Spline Interpolation By Solving A Recurrence Equation Instead Of A Tridiagonal Matrix, Peter Revesz

School of Computing: Conference and Workshop Papers

The cubic spline interpolation method is proba- bly the most widely-used polynomial interpolation method for functions of one variable. However, the cubic spline method requires solving a tridiagonal matrix-vector equation with an O(n) computational time complexity where n is the number of data measurements. Even an O(n) time complexity may be too much in some time-ciritical applications, such as continuously estimating and updating the flight paths of moving objects. This paper shows that under certain boundary conditions the tridiagonal matrix solving step of the cubic spline method could be entirely eliminated and instead the coefficients of the unknown cubic polynomials …

Single Spin Asymmetries In Charged Kaon Production From Semi-Inclusive Deep Inelastic Scattering On A Transversely Polarized 3He Target, C. Dutta, A. Kolarkar, Wolfgang Korsch, Y. X. Zhao, Y. Wang, K. Allada, K. Aniol, J. R. M. Annand, T. Averett, F. Benmokhtar, W. Bertozzi, P. C. Bradshaw, P. Bosted

Physics and Astronomy Faculty Publications

We report the first measurement of target single spin asymmetries of charged kaons produced in semi-inclusive deep inelastic scattering of electrons off a transversely polarized ³He target. Both the Collins and Sivers moments, which are related to the nucleon transversity and Sivers distributions, respectively, are extracted over the kinematic range of 0.1<x_bj<0.4 for K⁺ and K⁻ production. While the Collins and Sivers moments for K⁺ are consistent with zero within the experimental uncertainties, both moments for K⁻ favor negative values. The Sivers moments are compared to the theoretical prediction from a phenomenological fit to the …

A Quantitative Study Of Educational Poverty, School Location, And Student Achievement Measured By The Program For International Student Assessment (Pisa), Brett Barger

Dissertations

The performance of the United States’ students on international tests remains an ongoing source of concern, division, and anxiety for government, educational, and business leaders, teachers (and their unions), as well as the general public. These selfsame test results have been used as evidence to support diametrically opposed political and educational strategy and policy for decades. All too often the performance of students is discussed with a single test score number that is used to represent the entirety of the education system’s students without accounting for geographical, demographic, or socioeconomic differences among the student test takers. The contributing factors of …

Preparation Of Pre-Service Primary Science Teachers To Develop Scientific Literacy: A Case Of A Primary Teacher Training College In Taita Taveta County, Kenya, Angela Ndunge Kamanga

Master of Education

Scientific Literacy (SL) is a significant learning outcome among Pre-service Primary Science Teachers (PPSTs) in the 21st century. Owing to the crucial role of primary science tutors their knowledge and skills are indispensable in preparing PPSTs to develop SL. On the contrary, tutors currently exercise their practices without the prerequisite skills needed to develop the desired skills in the PPSTs. Consequently, the need for the Initial Teacher Education (ITE) to utilize learner centered approaches, and scientific inquiry skills to unlock their potential to prepare PPSTs to develop SL hence teach primary school learners to develop the same. This study sought …

Introduction To An Open Community Infrasound Dataset From The Actively Erupting Sakurajima Volcano, Japan, David Fee, Akihiko Yokoo, Jeffrey B. Johnson

Geosciences Faculty Publications and Presentations

Active volcanoes are significant sources of seismic and acoustic radiation. Extensive work has shown that infrasound is an effective tool to study and monitor active volcanoes. Infrasound is now a regular tool utilized by volcano observatories to aid in volcano monitoring and hazard mitigation. Infrasound‐based studies are able to provide important information on eruption dynamics and to develop quantitative models of volcanic eruptions. In addition, volcanoes provide excellent acoustic sources for atmospheric propagation studies and can be used to infer atmospheric dynamics and structure (see Johnson and Ripepe, 2011; Fee and Matoza, 2013 for recent reviews on volcano infrasound). The …

Common Hazards In Karst Terrain, Benjamin J. Currens, Alan Fryar, Carmen T. Agouridis

Agriculture and Natural Resources Publications

Karst refers to terrain largely drained by subsurface conduits and caves. Karst landscapes are characterized by surface features such as springs, sinkholes, shallow depressions, and rolling hills (Figure 1). Karst regions are also known for their subsurface or below-ground features such as conduits and caves (Figure 2). What makes a karst region unique is the way runoff drains from the land. In karst regions, some of the runoff flows into surface features such as sinkholes where it then travels underground. Some of this infiltrated water re-emerges at springs (Figure 1a), and some continues moving underground.

Irrigation Tips To Conserve Water And Grow A Healthy Lawn, Gregg Munshaw, Brad Lee

Agriculture and Natural Resources Publications

Turfgrasses are composed of thousands of cells, all containing water, in which metabolic processes such as photosynthesis and respiration take place. Water makes up 80 to 90 percent of the total plant mass. If this level drops below 60 percent, these processes may slow and wilting will occur. Water is critically important for:

• Maintaining turgidity, which keeps plants standing upright
• Transporting nutrients and sugars through the plant
• Chemical reactions
• Transpirational cooling when water moves out of the leaves and evaporates

Aerifying And Dethatching Lawns, Gregg Munshaw

Lawns in Kentucky will occasionally suffer due to compacted (hard) soils and excessive thatch layers. Although most lawns will not have problems with these issues, you may occasionally need to dethatch or aerify (core) to maintain a high quality lawn.

Mineral And Protein Blocks And Tubs For Beef Cattle, Jeff Lehmkuhler, Roy Burris, Donna M. Amaral-Phillips

Agriculture and Natural Resources Publications

Nutritional supplement blocks and tubs are convenient for beef producers, require no investment in feeding troughs and require a limited area for storing. One of the most attractive features is that they lower the labor needed to supplement livestock. Many producers use these products to provide supplemental nutrients to cattle consuming low-quality forages or as a mechanism to promote a more consistent intake of minerals. These products are also attractive to producers who have off-farm employment as they eliminate the need for daily feeding. Yet, they often come at a greater cost per unit of nutrient than more conventional feedstuffs. …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Effects Of Spreadsheet Towards Learners’ Usage Of Mathematical Language, C. Kok Fui, S.N.A. Syed Zamri

Research Publications (2011 to 2015)

Language has been an essential element in mathematics education as it is a tool used between individuals to convey the information of mathematical concepts. Some researchers discovered that inconducive language usage impedes mathematics learning. This papers reports on the effect of spreadsheet to the language used by a group of 32 pre-university students in defining “limits”. The data revealed that (i) spreadsheet changes learners’ commandment of language in three aspects which are usage of examples, types of expressions, and accuracy of terminology; (ii) spreadsheet does change learner’ choice expression while learning mathematics regardless their academic ability; and (iii) through spreadsheet …

Faculty and Staff Scholarship

We use a highly complete subset of the Galaxy And Mass Assembly II (GAMA-II) redshift sample to fully describe the stellar mass dependence of close pairs and mergers between 108 and 1012 M⊙. Using the analytic form of this fit we investigate the total stellar mass accreting on to more massive galaxies across all mass ratios. Depending on how conservatively we select our robust merging systems, the fraction of mass merging on to more massive companions is 2.0–5.6 per cent. Using the GAMA-II data we see no significant evidence for a change in the close pair fraction between redshift z …

Evidence For The Concurrent Growth Of Thick Discs And Central Mass Concentrations From S4g Imaging., S. Comeron, B. G. Elmegreen, H. Salo, E. Laurikainen, Benne W. Holwerda, J. H. Knapen

Faculty and Staff Scholarship

We have produced 3.6 μm + 4.5 μm vertically integrated radial luminosity profiles of 69 edge-on galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G). We decomposed the luminosity profiles into a disc and a central mass concentration (CMC). These fits, combined with thin/thick disc decompositions from our previous studies, allow us to estimate the masses of the CMCs, the thick discs, and the thin discs (ℳCMC, ℳT, and ℳT). We obtained atomic disc masses (ℳg) from the literature. We then consider the CMC and the thick disc to be dynamically hot components and the thin …

All students in both formats will also be given a periodic survey to …

A Quasi-Classical Logic For Classical Mathematics, Henry Nikogosyan

Honors College Theses

Classical mathematics is a form of mathematics that has a large range of application; however, its application has boundaries. In this paper, I show that Sperber and Wilson’s concept of relevance can demarcate classical mathematics’ range of applicability by demarcating classical logic’s range of applicability. Furthermore, I introduce how to systematize Sperber and Wilson’s concept of relevance into a quasi-classical logic that can explain classical logic’s and classical mathematics’ range of applicability.

Modeling Hedonic Processing And Anhedonia In Depression, Kevin Mercado

Honors College Theses

Depression is characterized by low positive emotion and a lack of pleasurable experiences, or anhedonia. Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event-related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes). In addition, several different hypotheses of emotional dysfunction were evaluated to accurately model deficits in positive emotionality. A majority of the psychophysiological tools used supported …

Centered-Difference Applications For Schrödinger's Equation, Matthew Thomas Murachver

Physics

This project enumerates methods utilizing discretized centered-difference approximations on the second order differential equation for quantum particles known as Schrodinger’s Equation. An eigenvalue-eigenfunction scheme is developed to sieve for valid solutions to The Time Independent Schrodinger Equation. Additionally the Crank-Nicolson method is applied to the Time Dependent Schrodinger Equation to describe wavefunction (eigenfunction) time evolution. The validity of these methods is discussed with applications to several fundamental pedagogical introductory quantum mechanic systems.
