  • How Metacognitive Awareness Relates to Overconfidence in Interval

    • Authors: Darci Klein et al.
      Abstract: Making judgments is an important part of everyday life, and overconfidence in these judgments can lead to serious consequences. Two potential factors influencing overconfidence are metacognitive awareness, or the awareness of one’s own learning, and the hard-easy effect, which states that overconfidence is more prevalent in difficult tasks while underconfidence is more prevalent in easy tasks. Overall, we hypothesized that participants’ metacognitive awareness would significantly relate to their overconfidence levels. Specific hypotheses were that those participants who display higher levels of metacognitive awareness will have lower levels of overconfidence, that harder questions will elicit higher levels of overconfidence and easy questions will elicit underconfidence (congruent with the hard-easy effect), and that the lower range and upper range will on average be equal, with the exact estimate as the midpoint. Participants (N = 49) completed a questionnaire containing a set of hard and easy general knowledge questions followed by the Metacognitive Awareness Inventory. The correlation between metacognitive awareness and confidence was negative for hard questions and positive for easy questions. Furthermore, the ranges for easy questions were smaller, resulting in more overconfidence, and the ranges for the hard questions were larger, resulting in underconfidence, thus, showing the opposite of our expected hypotheses.

  • Spelling, Handwriting, and Process: Writing Instruction Strategies for
           Students with Intellectual and Learning Disabilities

    • Authors: Charlotte Grace et al.
      Abstract: This manuscript examines how educators can improve their writing instruction for students with intellectual and learning disabilities. It outlines the challenges that these students face in writing and describes research conducted in these areas of need. The goal was to examine many studies and compare the methods used in them, with the objective of finding the most effective research-based practices to use in intermediate elementary classrooms. Specifically, this work analyzes writing in three different components: spelling, handwriting, and the writing process. Additionally, suggestions are included for pre-service teachers and early career in-service teachers.

  • Narrative of Difference: The Effects of Social Class on Belonging at
           Liberal Arts Colleges

    • Authors: Timothy E. Burnette
      Abstract: Low-income students have historically struggled in applying to colleges, especially liberal arts colleges. However, presently low-income students have had significantly more access to university due to changes in admission policies; the largest challenges now facing low-income students are during their time at university, where they struggle to maintain similar retention rates and comparable social and academic integration when compared to wealthier peers. In this research, I examined Grinnell College as a case study of liberal arts colleges as it is an interesting example due to no significant differences in average GPA or retention rates between social classes. I used an explanatory, sequential mixed-methods design to explore the experiences of low-incomes students at liberal arts colleges, focusing on belonging. I found that low-income students, despite claiming to belong at similar rates to wealthier peers, express narratives of difference where they have distinctly different experiences from wealthier peers. Differences included but are not limited to distinctive interpersonal relationships with faculty, staff, and peers, and low-income students’ lower participation levels in social events. However, despite these differences, low-income students often “work the system” to equalize their differences. Based on my findings, I propose a 7-point plan for improving the experiences of low-income students at liberal arts colleges.

  • The Rise of Structural Individualism: Millennial Attitudes toward Welfare
           and Poverty

    • Authors: Jamesha E. Watson et al.
      Abstract: This article examines college student attitudes towards social policy by linking how millennials define poverty and welfare to their beliefs about redistribution and policy changes. Using a mixed methodology, we develop a theory to explain why students often use structural definitions of poverty and social policy coupled with a reliance on individualistic solutions for individuals saddled with poverty or in need of social assistance. 450 surveys and 10 interviews were conducted to examine attitudes toward poverty, welfare policy, and people receiving welfare. The results, while not generalizable, shed light on how millennials think about the link between poverty and welfare.

  • Infant Mortality and Racism in the United States

    • Authors: Madison Grimm et al.
      Abstract: Significant health disparities exist in the United States with regard to infant mortality, a sensitive indicator of a nation’s health. The US has one of the highest infant mortality rates among OECD countries at nearly 6 infant deaths for every 1,000 live births. The rate for Black Americans (11.11 per 1,000) is more than double the rate for White Americans (5.06 per 1,000). Black American women are at higher risk of experiencing risk factors for infant mortality including preterm birth, low birthweight, and prenatal stress. The experience of racism from childhood through adulthood (personal experiences, vicarious experiences, and institutionalized structural racism) is likely a significant contributor to the disparity in infant mortality. This paper reviews the evidence for this and examines racism as a public heath issue.

  • The Difference in Efficiency and Pulmonary Function While Performing Cycle
           Ergometry on Land and in Water

    • Authors: Katherine M. Porter et al.
      Abstract: The purpose of this study was to quantify the difference in net efficiency and pulmonary function while performing cycle ergometry on land in water. Thirty healthy adults (mean ± SD, age, 20 ± 2 y; stature, 165 ± 10 cm; mass, 70 ± 5 kg) participated in one day of testing consisting of both land and water conditions. Heart rate, O2 consumption, CO2 production, rated perceived exertion, and minute ventilation were measured for both conditions at rest, pedaling at no resistance, 50, and 100 W for two minutes. A repeated measures two-way ANOVA with post hoc tests was used to analyzed the data. The magnitude of physiological functions (rated perceived exertion, minute ventilation, energy expenditure, & heart rate) increased at higher resistance levels (50 and 100W) in water as compared to land. Efficiency decreased at 50 and 100W in water. Energy expenditure and minute ventilation both increase while cycling in water, resulting in a decrease of efficiency by 4.61%. This is due to the drag forces associated with fluid dynamics. This study and its results add to the understanding of water exercise and are beneficial to the rehabilitation and the general well-being and health of the population.

  • College Students’ Attitudes toward Debt

    • Authors: Elliott M. Beale et al.
      Abstract: College student debt has gained much attention. This article uses survey data to examine the influence of psychological factors on college student attitudes toward debt. In the sample of 283 undergraduates enrolled in a personal finance elective course, financial self-confidence was significantly related to debt attitude, indicating that less financially self-confident students tended to have more positive attitudes toward debt. Two other psychological factors, ability to delay gratification and comparing oneself to others, were not significantly related to debt attitudes. Among the control variables, only gender was significantly related; women had more negative attitudes toward debt than men. College major, involvement with parents about personal finance, and financial knowledge were not significantly related to student attitudes toward debt. Future researchers should consider reexamining the use of the scales used in this research. Although the scales had been used by previous researchers, they may have less relevance to young adults whose debt attitudes were no doubt influenced by the Great Recession of 2007-2009.

  • Designing and Evaluating the Quality and Cost-effectiveness of Saturated
           Sediment Permeameters

    • Authors: Caleb Gibson et al.
      Abstract: Many simulations require accurate measurements of saturated hydraulic conductivity, a sediment property that governs the speed at which water flows through sediments relative to head differences. The goal of our project is to design and build an inexpensive permeameter capable of producing accurate hydraulic conductivity values. We tested four permeameters; a standard research grade constant-head permeameter, a falling-head permeameter modeled off of an in situ stream method, a constant-head permeameter made out of 4” PVC pipe, and a similar constant-head permeameter made out of 2” PVC pipe. Our custom-built constant-head permeameters both utilized a U-shaped design, two tubes which form a manometer, and multiple output overflows. Despite significant differences in design, method, and cost, we found that all four of the permeameters yielded relatively consistent mean hydraulic conductivities with low standard deviations (0.004-0.019). We also compared the attributes: price, weight, and number of parts. Our conclusion is that because the average K-value and standard deviation of each design is within reason, the best choice depends on the practitioner’s situation and intention.

  • Rape Myth Acceptance and Willingness to Intervene: A Comparison of
           Greek-Affiliated and Non-Affiliated College Students by Gender

    • Authors: Mark E. Pettit et al.
      Abstract: Fraternity and sorority members are overrepresented as perpetrators and victims of sexual assault, respectively. The current study examined rape myth acceptance, bystander attitudes, and bystander efficacy across four groups: sorority women, fraternity men, non-affiliated women, and non-affiliated men. Data were collected from 912 college undergraduates. Greek affiliated students were more accepting of rape myths than non-affiliated students. There were no differences in bystander attitudes based on Greek affiliation; however, Greek affiliated students did report significantly lower bystander efficacy than non-affiliated students. Sorority women and fraternity men reported no differences in their acceptance of rape myths or bystander efficacy; however, sorority women did report higher bystander attitudes than fraternity men. Based on the findings, it is recommended that prevention practitioners work to change norms within fraternities and sororities to promote a social identity that is associated with gender equality and a willingness, perhaps even an obligation, to intervene in risky situations.

  • Generating Road Network Graph with Vision-Based Unmanned Vehicle

    • Authors: Henrique Yano et al.
      Abstract: With the advancement of technology and its cheapness, robotic vehicles have gained a large number of applications. The spread of their use is growing also because they are getting smaller, lighter and easier to build. In this paper we present a simple and effective way to map a road network with the help of a driverless vehicle. Our approach consists of only three parts: vision-segmentation, angle variation and travelled distance. A video camera attached to a Lego® NXT Mindstorm vehicle guides it by image segmentation using Matlab® Image processing toolbox, along a road network, in which is represented by black tape over a white floor. The algorithm makes the vehicle travel all over the road memorizing main coordinates to identify all crossroads by keeping track of the travelled distance and the current angle. The crossroads and road’s end are the nodes of the graph. After several simulations have been performed, the modelling proved to be successful in that small scale approach. Consequently, there are good chances that driverless cars and UAVs also make use of the strategies to map route networks accordingly. The algorithm presented in this paper is useful when there is no localization signal such as GPS, for example, navigation on water, tunnels, inside buildings, among others.

  • Developing a Protocol for Creating Microfluidic Devices with a 3D Printer

    • Authors: Robyn Collette et al.
      Abstract: Microfluidics devices have high importance in fields such as bioanalysis because these devices have the ability to manipulate small volumes of fluid, typically ranging from microliters to picoliters. Small samples of fluids can be quickly and easily tested using reactions performed with complex microfluidic devices. Many methods have been previously developed to create these devices, including traditional nano- lithography techniques borrowed from the field of microelectronics. However, these traditional techniques are cost-prohibitive for many small-scale laboratories. This research explores a relatively low-cost technique using a 3D printed master, which is used as a template for the fabrication of polydimethylsiloxane (PDMS) microfluidic devices. The masters are designed using computer aided design (CAD) software and can be printed and modified relatively quickly. We have developed a protocol for creating simple microfluidic devices using a 3D printer and PDMS adhered to glass. We have also explored methods to overcome the size-limits of the 3D-printed master templates by using shrinkable polymers and modified channel geometries to create a flow-focusing channel. This relatively simple and lower-cost technique can now be scaled to more complicated device designs and applications.

  • Dance Under the Swastika: Rudolf von Laban's Influence on Nazi Power

    • Authors: Christine Dickson
      Abstract: This investigation of esteemed dance artist Rudolf von Laban’s early career examines his involvement with the Nazi regime while working as the director of the German Dance Theater (Deutchen Tanzbuhne). During this time, he actively ensured the upholding of Aryan and National Socialist ideals in dance performance and training, and used his own ensemble-based choreography to promote the creation of community under the swastika. Many dance scholars, focused on the numerous contributions Laban made to the development of modern dance, tend to consider his actions between 1930-1937 to have been coerced or executed out of fear for his life. However, based on official Nazi documentation and accounts and timelines of Laban’s actions and personally written beliefs, the author suggests that Laban’s alignment with the Third Reich was intentional and not the result of coercion or manipulation.

  • Arabidopsis thaliana growth more than defense affects Myzus persicae

    • Authors: Biran S. Falk-Dotan et al.
      Abstract: Aphids and other herbivorous insects are able to travel between plants in their environment. While plants cannot directly choose their consumers, they may stop or mitigate the harmful effects of herbivory using secondary metabolites. A salicylic acid (SA) pathway facilitates defense from biotrophic fungi and some necrotrophic pathogens, while a jasmonic acid (JA) pathway is associated with defense from other necrotrophic pathogens and chewing insects. We investigated the effect of deficiency in SA or JA in Arabidopsis thaliana on plant growth and on herbivory by green peach aphids (Myzus persicae). Three ascensions of A. thaliana were placed in two blocks with three aphids on each individual. The genotypes consisted of a SA-deficient ascension (Sid2), a JA-deficient ascension (Lox2), and a wild type (Col). Wild-type A. thaliana showed significantly greater growth relative to the other ascensions, suggesting better performance, as well as dramatically higher aphid count. Aphid count showed a significant positive correlation with plant growth, suggesting that M. persicae is attracted to signs of growth in A. thaliana, or reproduces more on growing plants. It appears that wild-type plants showed greater growth throughout the experiment, and were thus targeted by the highly responsive M. persicae. This behaviour may be exploited for agricultural purposes; herbivorous insects may be diverted to fast-growing trap crops lacking agricultural value in order to protect primary crops.

  • Gender Differences in Rough and Tumble Play Behaviors

    • Authors: S. Julie Harbin
      Abstract: I conducted 10 one-hour observations in a Kindergarten classroom to determine if there were gender differences in the types of Rough and Tumble play (RTP) that children engaged in. Previous research reported that (a) boys were more likely than girls to engage in RTP, (b) boys were more likely than girls to engage in solitary forms of RTP, (c) girls were more likely than boys to engage in collaborative forms of RTP, and (d) boys were more likely than girls to engage in aggressive forms of RTP. My findings were similar to those of previous research. I found that boys participated in RTP more than girls and the forms of RTP engaged in by boys were more aggressive. I also found that boys engaged in more solitary RTP than girls, although both boys and girls engaged in more solitary than collaborative RTP. Unlike previous research findings, boys and girls in my study engaged in similar rates of collaborative RTP. I also found that the presence of one particular girl influenced the occurrence of collaborative mixed-gender RTP, which I refer to as the "Amber Effect." The influence of one player on the likelihood of RTP occurring has not been reported in previous research.

  • A Mixed-Methods Exploration of the Relationship Between Crime and
           Community Gardens: A Case Study of Seattle’s P-Patches from 1996 to 2006

    • Authors: Taylor L. Frazier et al.
      Abstract: Urban community gardens have been shown to have positive affects social capital, yet like many public spaces, are open to negative activities like crime. Contrary to this idea, most of the literature has indicated that urban green spaces are associated with a reduction in crime. This study utilized a mixed-methods research design to explore the hypothesis that areas around Seattle’s “P-Patch” community gardens are associated with a reduction in crime. We employed spatio-temporal GIS (Geographic Information Systems) analyses, statistical analyses, and qualitative interviews with gardeners. Yearly violent and property crime rates for 132 census tracts in Seattle, locations of 84 P-Patches were mapped, and changes in crime and garden establishment from 1996 to 2006 were observed. Correlations were conducted on socio-demographic, crime, and P-Patch variables. Interviews with four gardeners were conducted and qualitatively analyzed for common themes. Geographic visualization showed interesting patterns in crime and P-Patch establishment in South Seattle in particular, but outcomes of the correlation between P-Patch and crime variables were inconclusive. Qualitative interviews with gardeners provided a fuller account of the overall changes in Seattle crime, gardeners’ perceptions of neighborhood safety, and its relation to the development of urban community spaces such as P-Patches.

  • Computational Modelling of a Spanning Drop in a Wedge with Variable Angle

    • Authors: Caio Rondon et al.
      Abstract: In this work, mathematical and computational techniques were used to model the phenomenon of a bubble or liquid drop as it slides to the narrowest side between two tilted plates. Practical applications of this phenomenon, such as the adjustment of liquid propellant tanks, are also discussed. Computations involved the use of Surface Evolver—a fully open, interactive program that allows the simulation of physical experiments in a virtual environment.

  • Towards the Selective Inhibition of Glycolytic Pathway Enzymes: A
           Computational Analysis of Plasmodium falciparum and Human Triosephosphate
           Isomerase Ligand Interactions.

    • Authors: Nicoleta Alexandru et al.
      Abstract: Plasmodium falciparum is main causative agent of malaria, a disease that affects half of world’s population. The parasite’s dependence on glycolysis makes this pathway a suitable target for drug development. Understanding the structure-function dynamics of glycolytic enzymes in different species has an important impact on the development of selective drug analogues. Parasitic resistance and drug side effects of current antimalarial drugs have complicated and increased the cost of curing malaria.Molecular docking was used to explore structural motifs responsible for the interactions between triose phosphate isomerase (TIM) from Plasmodium falciparum (PFTIM) and human (HTIM) tissues. Fourteen antimalarial drugs were examined. The binding affinities and domains identified serve as a basis for modeling novel analogues.For all drugs modeled, PFTIM complexes displayed stronger binding affinities compared to HTIM. A dissociation constant (KI) of 40.2 mM was obtained for the interaction between primaquine and HTIM and 1.22 mM with PFTIM. This represents a 33-fold increase in selective binding to PFTM compared to HTIM. Mefloquine shows a 24-fold increase, and one new test ligand showed 25-fold increase in binding.The dimer interface and other pocket close to the active site are the main pockets observed by the docking studies. Key residues at the dimer interphase (Y48, D49, V46, S45, E65, S211) form a tight pocket with favorable polar contacts. 75% of PFTIM ligand complexes preferred the dimer interphase suggesting a potential site for non-competitive inhibition. These data suggest that TIM is a candidate for development of antimalarial drugs.

  • Feminist Themes in Philip Roth’s Goodbye, Columbus

    • Authors: Haley E. Van Bellingham
      Abstract: The current article presents evidence that, in his novella Goodbye, Columbus, Philip Roth should be commended for illustrating the limitations placed on women in Jewish-American culture during the 1950s, rather than criticized for exhibiting the misogynistic viewpoints of that era. Roth uses a combination of male narration and female characterization to show the limited opportunities available to women. Brenda, the primary female protagonist, is presented from the perspective of the male narrator, Neil, as frustrating and incomprehensible. This characterization demonstrates the difference between Neil’s way of thinking, as a male, and Brenda’s as a female. Brenda is an affluent character who demonstrates that wealth alone cannot provide a woman with opportunities and freedoms that equal even those available to males of lesser status. Brenda lacks freedom, financially because of her lack of options as a woman, within her own skin because of a lack of autonomy over her body within sexual relationships, and over her self-image because of the criticism she experiences from her mother and the expectations placed upon her by her parents as a Jewish woman in 1950s society. The current article, therefore, argues that what is often misinterpreted as misogyny in Roth’s use of criticism of Brenda’s character by Neil is, in fact, a vivid demonstration of the lack of options and autonomy available to women in that era.

  • Bayesian Techniques for Surface Fuel Loading Estimation

    • Authors: Ryan Karpisz et al.
      Abstract: In previous work, researchers compared three sampling techniques for estimating the biomass of surface fine woody fuels by using them on known distributions. An important result was that precise estimates of fuel biomass required intensive sampling for both planar intercept and fixed-area methods. This study explores Bayesian statistical methods as a means to reduce the sampling effort needed to obtain a desired precision. We examined how initial estimates of the minimum and maximum fuel loading at a site could be used as prior information in a Bayesian framework. We found that, under certain scenarios, Bayesian techniques dramatically increased the precision of the estimator compared to using no prior information from the site.

  • The Photophysical Properties of CdTe/ZnS Core/Shell Quantum Dots

    • Authors: Christopher Z. Eddy et al.
      Abstract: The distinctive fluorescent properties of semiconductor nanocrystal quantum dots (QDs) make them advantageous for use in optoelectronic and biological applications. We report on experiments done to characterize the optical properties and the general photostability of CdTe QDs with varying ZnS shell thicknesses. Steady-state and time-resolved absorption and fluorescence spectroscopy measurements indicate that increasing the ZnS shell thickness results in longer absorption and emission wavelengths, increased quantum yield, and improved photostability.
