Beyond Post-Modernity In Mathematics Education, Ole Skovsmose

The Mathematics Enthusiast

A radical form of postmodernity is presented with reference to Nietzsche’s ideas with respect to truth, knowledge, sciences, progress, democracy, and ethical values in general. Thereafter is presented Foucault’s archaeology of knowledge. This brings us forward to the notion of genealogy, which is a defining idea for the postmodern conception of critique. However, it is emphasised that a critique can address the generativity of mathematical rationality by considering mathematics-based fabrications. Finally, imagination is presented as yet another feature of a critical enterprise. It is illustrated how such a three dimensional critical enterprise is relevant for both mathematics and mathematics education. …

Foundations For Success In Mathematical Competitions: A Study Of Best Praxis In Lower Secondary Schools In Norway, Steinar Thorvaldsen, Lars Vavik

Will the teacher’s education and pedagogical praxis have an impact on good learning results? We report results from a case-control association study on among high achievement classes in mathematics in Norway. The data were collected from matched pairs of schools, paired on the basis of location and socioeconomic status. The questionnaire was first distributed to teachers in 38 Norwegian secondary schools at grade 9, which have had repeated success in the annual …

Silicon: A Benefit Or A Detriment To Plant Physiology For Creeping Bent (Agrostis Stolonifera L.), Sheep's Fescue (Festuca Ovina L.) And Perennial Ryegrass (Lolium Perenne L.)?, Nicola Warburton, Jo Bayley, Stuart Lane

The Plymouth Student Scientist

Silicon shows alleviatory effects in many previous studies involving abiotic and biotic stress factors. A germination trial for the optimum concentration of ERA-3 initially showed an optimum dilution factor of 2,500:1 (Distilled water: ERA-3). Over one hundred individuals of each species of Agrostis stolonifera L., Festuca ovina L. and Lolium Perenne L. were all grown for eight weeks in closed hydroponic systems, in warmed greenhouse conditions (15°C). When solely tested, the effects on all three species showed contrasting results to what was expected. In all three selected species, silicon significantly reduced the shoot area, and photosynthetic efficiency (measured as Fv/Fm …

Displays Of Personal Adornent And Body Decoration By Nineteenth Century Lakota (Sioux) Tribes: A Costly Signaling Model, Michelle L. Night Pipe

Department of Anthropology: Theses and Student Research

Throughout the nineteenth century, Lakota (Sioux) individuals devoted an enormous amount of time, energy, and resources to the production and purchase of lavish clothing, headdresses, and accessories. These items seemingly lack any practical value, making them difficult to account for in economic terms. Costly signaling theory, however, predicts that the costs of the production of personal adornment and body decoration may be offset by the accumulation of prestige. For Lakota men, prestige translated into higher status, membership in warrior and headmen's societies, leadership opportunities, marital opportunities, and ultimately, differential reproductive success. Lakota women also garnered prestige based on the quality …

Taking The Stand: Access To Justice For Witnesses With Mental Disabilities In Sexual Assault Cases, Janine Benedet, Isabel Grant

Osgoode Hall Law Journal

In this article the authors argue that the existing adversarial trial process often prevents the stories of sexual assault complainants with mental disabilities from being heard in court. Relying on social science evidence, the authors argue that subjecting a woman with a mental disability to a rigorous cross-examination with repeated and leading questions, in a manner that is confrontational and often accusatory, is probably the worst way to get her story heard accurately in court. It is likely to unfairly undermine her credibility and to result in unjustified acquittals or in prosecutors deciding not to pursue a case. The article …

Wing Shape As An Indicator Of Larval Rearing Conditions For Aedes Albopictus And Aedes Aegypti (Diptera: Culicidae), C R. Stephens, Steven A. Juliano

Faculty Publications – Biological Sciences

Estimating a mosquito's vector competence, or likelihood of transmitting disease, if it takes an infectious bloodmeal, is an important aspect of predicting when and where outbreaks of infectious diseases will occur. Vector competence can be affected by rearing temperature and inter- and intraspecific competition experienced by the individual mosquito during its larval development. This research investigates whether a new morphological indicator of larval rearing conditions, wing shape, can be used to distinguish reliably temperature and competitive conditions experienced during larval stages. Aedes albopictus (Skuse) and Aedes aegypti (L.) (Diptera: Culicidae) larvae were reared in low intraspecific, high intraspecific, or high …

Analysis Of Translating Hydrofoil Power Generation Systems (Hydrokites), Kelsey Mcconnaghy

Theses

The hydrokite is a novel hydro-power system that is based on emerging kite wind-energy systems which are currently being designed for use at high altitudes. The hydrokite system is comprised of a hydrofoil and a support system, and is designed to capture kinetic energy from the flow of a river while reducing negative impacts on the river ecology by minimally interfering with the rivers natural flow (i.e. no dams or river diversions are needed). This work presents some initial results which demonstrate the power performance capabilities of the hydrokite. Two different steady-state models for this system were studied to determine …

Fostering Ecological Citizenship: The Case Of Environmental Service-Learning In Costa Rica, Jennifer Rebecca Kelly, Troy D. Abel

International Journal for the Scholarship of Teaching & Learning

The intent of this study was to explore how experiential education fosters ecological or environmental citizenship. In this context, we investigated the impact of international environmental service-learning in a college course. Specifically our research question was does environmental service-learning have an effect on ecological citizenship? Using a multimethod approach of both qualitative and quantitative instruments our study drew on 13 participant interviews, 19 student journals and 10 survey responses. Employing variables from the Value-Belief-Norm Theory our findings suggest that environmental service-learning experiences impact both awareness of environmental consequences and personal normative beliefs. We conclude that ecological citizenship was indirectly impacted …

War Without Violence: Leveraging The Arab Spring To Win The War On Terrorism, Pat Proctor

Journal of Strategic Security

After a decade of war, the United States has failed to eradicate the threat of salafist jihadism. No matter how hard it tries, the United States cannot kill its way to victory in the war on terrorism. Sweeping changes across the Middle East—dubbed the "Arab Spring" by the media—have presented the West with a unique opportunity to pursue an alternative approach. Rather than engaging in war (politics through violence), the United States should engage in mass politics (war without violence) to compel the Arab world to reject the salafist jihadism idea. This article proposes a strategy calibrated to defeat international …

Attitudes Toward Workplace Mobbing In Slovenian Research Organisations, Brigita Horvat, Milan Pagon

All Works

Creating a "mobbing-safe" working environment can be a real challenge; to achieve it, a better understanding of related constructs is necessary. To obtain insight into researchers' attitudes toward workplace mobbing and behavioural intentions, we used a case scenario method. The results show that respondents, on average, consider the mobbing cases presented in a questionnaire to be very serious. Their attitudes and behavioural intentions depend more on their opinion about colleagues' attitudes and related intentions and less on their own, which shows a lower integrity than desired. Low willingness to report the violator, lenient discipline sanctions and the absence of proper …

Environmental Damages After The Federal Environmental Enforcement Act: Bringing Ecosystem Services To Canadian Environmental Law?, Martin Z. P. Olsynski

Osgoode Hall Law Journal

The Canadian Environmental Enforcement Act [EEA] directs judges to consider actual environmental damage, or risk thereof, when setting fines for environmental offences. The EEA defi nes damage as including the loss of use and non-use values. While these terms are not unprecedented in Canadian environmental law, their use in environmental damage assessment is. Bearing in mind recent developments in environmental valuation in the United States and internationally, and considering the emergence of the “ecosystem services” paradigm in particular, this article explores the opportunities and challenges for ecosystem services based environmental damages assessment in the Canadian environmental sentencing context. The ecosystem …

Adaptive Optics Scanning Ophthalmoscopy With Annular Pupils, Yusufu N. Sulai, Alfredo Dubra

Biomedical Engineering Faculty Research and Publications

Annular apodization of the illumination and/or imaging pupils of an adaptive optics scanning light ophthalmoscope (AOSLO) for improving transverse resolution was evaluated using three different normalized inner radii (0.26, 0.39 and 0.52). In vivo imaging of the human photoreceptor mosaic at 0.5 and 10° from fixation indicates that the use of an annular illumination pupil and a circular imaging pupil provides the most benefit of all configurations when using a one Airy disk diameter pinhole, in agreement with the paraxial confocal microscopy theory. Annular illumination pupils with 0.26 and 0.39 normalized inner radii performed best in terms of the narrowing …

International Journal for the Scholarship of Teaching & Learning

Recently, twenty-one instructors at a Midwestern university participated in a faculty development seminar entitled, “Developing Pedagogies to Enhance Excellence and Diversity.” They designed a pedagogical change for the following academic year based on the workshop. During the following year, we collected data on the workshop participants through surveys and interviews to discover if they had implemented the proposed changes and what they discovered in the process. Thirteen of the twenty-one participants responded to our request for information and nine implemented their proposed changes during our data collection. Reviewing the data, we found three areas where participants made changes: application of …

Analysis Of The Effectiveness Of Traditional Versus Hybrid Student Performance For An Elementary Statistics Course, Kamal M. Kakish, Lissa Pollacia, Adrian Heinz

International Journal for the Scholarship of Teaching & Learning

This paper investigates the performance of students enrolled in traditional versus hybrid Elementary Statistics courses at Georgia Gwinnett College (GGC). For this study, we collected and analyzed student performance data for the course goals over the spring semester of 2011. GGC is unique as it is an open access undergraduate institution, which has experienced rapid growth since its recent foundation in 2006. This presents a distinct challenge because there is a diverse student population, with various degrees of mathematical knowledge and learning capabilities. Based on the results of our findings, we have discovered that there is no significant difference between …

Association Of A Serotonin Transporter Gene (Slc6a4) 5-Httlpr Polymorphism With Body Mass Index Categories But Not Type 2 Diabetes Mellitus In Mexicans, Valeria Peralta-Leal, Evelia Leal-Ugarte, Juan P. Meza-Espinoza, Ingrid P. Dávalos-Rodríguez, Anabel Bocanegra-Alonso, Rosa I. Acosta-González, Enrique Gonzales, Saraswathy Nair, Jorge Durán-González

Health & Biomedical Sciences Faculty Publications

The serotonergic system has been hypothesized to contribute to the biological susceptibility to type 2 diabetes mellitus (T2DM) and body-mass index (BMI) categories. We investigate a possible association of 5-HTTLPR polymorphism (L and S alleles) in the promoter region of the serotonin transporter gene (SLC6A4) with the development of T2DM and/or higher BMI by analyzing a sample of 138 individuals diagnosed with T2DM and 172 unrelated controls from the Mexican general population. In the total sample genotypes were distributed according to Hardy-Weinberg equilibrium, and S allele frequency was 0.58. There was no statistical association between 5-HTTLPR polymorphism and the development …

Examining Lower Extremity Motor Activity Using Magnetoencephalography, Ruth M. Swedler

Master's Theses (2009 -)

The role of the cortex during locomotion remains unclear, but recent advances in neural imaging technologies have aided in developing ways to measure brain activity during motor tasks. One method is by measuring activations produced by neural oscillations which have been associated with a variety of human behaviors, from sleep and rest to cognitive actions and movement. The physiological and functional methods in which oscillations contribute to cortical control are still largely unknown. In this study, we aim to expand that knowledge by examining human cortical activity in the sensory and motor cortices during pedaling using magnetoencephalography (MEG). We hypothesized …

Culivating And Retaining Committed Volunteers: An Analysis Of Volunteer Identification In Nonprofit Organizations, Nora Beth Pilak

Master's Theses (2009 -)

With nonprofit organizations expanding due to a weakened economy and a growing population, there is an increased need for volunteers to staff and support these organizations. Since most nonprofits operate with limited finances, these organizations have to generate and retain a group of effective and committed unpaid organizational members. In this study, I argue that the best way for nonprofits to cultivate efficient and dedicated volunteers is to use communication tactics that encourage members to identify with the organization. I also argue that if volunteers strongly identify with an organization, they are more likely to continue contributing their time and …

De Novo Protein Structure Modeling From Cryoem Data Through A Dynamic Programming Algorithm In The Secondary Structure Topology Graph, Kamal H. Al Nasr

Computer Science Theses & Dissertations

Proteins are the molecules carry out the vital functions and make more than the half of dry weight in every cell. Protein in nature folds into a unique and energetically favorable 3-Dimensional (3-D) structure which is critical and unique to its biological function. In contrast to other methods for protein structure determination, Electron Cryorricroscopy (CryoEM) is able to produce volumetric maps of proteins that are poorly soluble, large and hard to crystallize. Furthermore, it studies the proteins in their native environment. Unfortunately, the volumetric maps generated by current advances in CryoEM technique produces protein maps at medium resolution about (~5 …

Assessing Movement Of Fish Through Spectral Analysis Of Otolith Life History Scans, Renee Reilly Hoover

OES Theses and Dissertations

The ability to accurately measure movement timing across environmental gradients is fundamental for testing hypotheses in marine ecology that deal with ingress, egress, and migration of fish. Timing and patterns of movement have been estimated using life-history scans of the chemical signatures encoded in fish otoliths (ear stones). I provide a quantitative approach to examining life history scan data using spectral analysis, which retrospectively measures the movement timing for individual fish. Sagittal otoliths from juvenile Atlantic croaker (Micropogonias undulates) and adult black sea bass (Centropristis striata) were sampled using laser ablation inductively coupled plasma mass spectrometry …

Attending To Detail By Communal Spider-Eating Spiders, Robert R. Jackson, Ximena J. Nelson

All Peer-Reviewed Publications

Communal predators may often need to make especially intricate foraging decisions, as a predator's success may depend on the actions of its neighbours. Here, we consider the decisions made by Portia africana, a jumping spider (Salticidae) that preys on other spiders, including Oecobius amboseli (Oecobiidae), a small prey spider that lives under small sheets of silk (nests) on the walls of buildings. P. africana juveniles settle near oecobiid nests and then ambush oecobiids as they leave or enter the nest. Two or more P. africana juveniles sometimes settle at the same nest and, when an oecobiid is captured, the P. …

Online Kernel Selection: Algorithms And Evaluations, Tianbao Yang, Mehrdad Mahdavi, Rong Jin, Jinfeng Yi, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

Kernel methods have been successfully applied to many machine learning problems. Nevertheless, since the performance of kernel methods depends heavily on the type of kernels being used, identifying good kernels among a set of given kernels is important to the success of kernel methods. A straightforward approach to address this problem is cross-validation by training a separate classifier for each kernel and choosing the best kernel classifier out of them. Another approach is Multiple Kernel Learning (MKL), which aims to learn a single kernel classifier from an optimal combination of multiple kernels. However, both approaches suffer from a high computational …

Seasonal Photoperiods Alter Developmental Time And Mass Of An Invasive Mosquito, Aedes Albopictus (Diptera: Culicidae), Across Its North-South Range In The United States, Steven A. Juliano, Donald A. Yee, Steven M. Vamosi

Faculty Publications – Biological Sciences

The Asian tiger mosquito, Aedes albopictus (Skuse), is perhaps the most successful invasive mosquito species in contemporary history. In the United States, Ae. albopictus has spread from its introduction point in southern Texas to as far north as New Jersey (i.e., a span of approximate to 14 degrees latitude). This species experiences seasonal constraints in activity because of cold temperatures in winter in the northern United States, but is active year-round in the south. We performed a laboratory experiment to examine how life-history traits of Ae. albopictus from four populations (New Jersey [39.4 degrees N], Virginia [38.6 degrees N], North …

A Business Plan For Grass Fed Restaurant, Joshua Schonfeld

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper will present a business plan for a grass fed steakhouse concept in Chicago. After having spent the past year researching the grass fed meat market, meeting with grass fed farmers and looking for restaurant locations in three different markets (Los Angeles, San Francisco and Chicago) it has become apparent that Chicago is going to be the best market for this type of concept. In the restaurant industry, contacts and word of mouth are two huge players in success in the restaurant business and this is definitely a connection that the partners have in Chicago.

Why grass fed? As …
