Influence of Rap and Hip-hop Lyrics on Male Body Image and Attitudes Toward Wwomen
Rap and hip-hop music are a widely popular and accessible genre of media. Its popularity and controversial lyrics raise questions as to the effects it may have on its audience. This study proposes to investigate the influence of rap and hip-hop music will be correlated with higher mean levels of thin-ideal appearance internalization (INT-GEN), negative attitudes towards women, and cultural expectations of masculinity compared to published normative data. Participants will complete online measures addressing questions about their body image (e.g. drive for muscularity) and attitudes toward women (e.g. objectification and misogyny). Future research should compare the influence of rap and hip-hop music on male and female\u27s self-concept and attitude formation based on the gender of the artist
Using Culturally Responsive Teaching with Culturally and Linguistically Diverse Students with Specific Learning Disabilities to Increase Performance in Algebra I
As the United States (U.S.) population continues to change and become racially/ethnically, culturally, linguistically, and economically diverse, so does the population in public schools (Institute of Education Sciences, 2010). Additionally, the number of culturally and linguistically diverse (CLD) students has been overrepresented in the subgroup of students with learning disabilities (SLD) (Artiles & Ortiz, 2002; Kalynpur & Harry, 2012; Klingner & Harry, 2014). Therefore, there is a need to adapt the curriculum and pedagogy to teach the growing number of diverse students in public schools. The results of national assessments show that students of color have lagged behind their White counterparts in mathematics achievement over the years (Cortes, Goodman, & Nomi, 2013). Despite the push to remediate this problem, teachers continue to use ineffective teacher-led practices and the achievement gap persists across public schools (Williams, 2011).
The use of cultural responsive teaching (CRT) among CLD students is promising (Santamaria, 2009). However, there is need to investigate the use of these practices in Algebra I courses with CLD students with SLD.
The present 17-week pre-post study compared student achievement in Algebra I courses between two groups of CLD students with SLD (N=63). These groups were (a) 31 students who received CRT (treatment group) by teachers who received CRT training and (b) 32 students who received instruction by teachers who did not receive CRT training (control group). There are significant differences between the treatment and the control group on the CLD students with SLD Algebra I Mid-Year Assessment (MYA) and the students’ Mathematics Self-Efficacy scores (MSES). The teachers’ level of cultural consciousness had an insignificant covariance on the Algebra I MYA, yet the teachers’ observations and their cultural responsive self-assessment had a direct effect on the Algebra I MYA. Additionally, there was not significant interaction between MSES and TCS on the students’ Algebra I MYA. The results of the study suggest that the use of CRT is a promising practice to improve CLD students’ with SLD Algebra I achievement and perhaps close the math achievement gap
The Hexatangle
We are interested in knowing what type of manifolds are obtained by doing
Dehn surgery on closed pure 3-braids in the 3-sphere. In particular, we want to
determine when we get the 3-sphere by surgery on such a link. We consider links
which are small closed pure 3-braids; these are the closure of 3-braids of the
form ,
where , are the generators of the 3-braid group and ,
, are integers. We study Dehn surgeries on these links, and determine
exactly which ones admit an integral surgery producing the 3-sphere. This is
equivalent to determining the surgeries of some type on a certain six component
link that produce . The link is strongly invertible and its
exterior double branch covers a certain configuration of arcs and spheres,
which we call the Hexatangle. Our problem is equivalent to determine which
fillings of the spheres by integral tangles produce the trivial knot, which is
what we explicitly solve. This hexatangle is a generalization of the Pentangle,
which is studied by Gordon and Luecke.Comment: 31 pages, 9 figure

Drones as a Tool to Monitor Human Impacts and Vegetation Changes in Parks and Protected Areas
Increased visitation to protected areas could have adverse impacts on the conservation values in the protected areas, and therefore effective visitor monitoring methods are needed to meet the complex management challenges that arise. Collecting data on human impacts is highly time consuming, thus requiring more effective tools that allow for high-quality and long-term measurements. In this study, we show how unmanned aerial vehicles (i.e. UAV or drones) could be used to monitor tourism impacts in protected areas. Tourism has boomed in national parks in Norway in recent years, such as in Jotunheimen National Park for which this study applies. We test the use of drones on a site where new tourist facilities will be established to set a baseline to identify future changes. We demonstrate how drones could help protected area management by monitoring visitor use patterns and commonly associated impacts such as trail condition (width and depth), vegetation structure and disturbances, informal trail proliferation, trampling, and trash and other impacts along the trails. We assessed accuracy and reliability compared with intensive field measurements of impacts and found low-cost drones to be effective in mapping the study area with a resolution of 0.5 cm/pixel: drone derived trail measurements were comparable to traditional measurements with a negligible divergence on trail width measurements and a consistent 1.05 cm divergence on trail depth measurements that can be corrected with a few validation points. In addition, we created a high-resolution vegetation classification map that could be used as a baseline for monitoring impacts. We conclude that drones can effectively contribute to visitor monitoring by reducing time spent in the field and by providing high-resolution time series that could be used as baseline to measure tourism impacts on conservation values in protected areas
Gene therapy with Angiotensin-(1-9) preserves left ventricular systolic function after myocardial infarction
BACKGROUND: Angiotensin-(1-9) [Ang-(1-9)] is a novel peptide of the counter-regulatory axis of the renin angiotensin system previously demonstrated to have therapeutic potential in hypertensive cardiomyopathy when administered via osmotic minipump in mice. Here, we investigate whether gene transfer of Ang-(1-9) is cardioprotective in a murine model of myocardial infarction (MI).
OBJECTIVES: To evaluate effects of Ang-(1-9) gene therapy on myocardial structural and functional remodeling post infarction.
METHODS: C57BL/6 mice underwent permanent left anterior descending coronary artery ligation and cardiac function was assessed using echocardiography for 8 weeks followed by a terminal measurement of left ventricular (LV) pressure-volume loops. Ang-(1-9) was delivered by adeno-associated viral vector via single tail vein injection immediately following induction of MI. Direct effects of Ang-(1-9) on cardiomyocyte excitation–contraction coupling and cardiac contraction were evaluated in isolated mouse and human cardiomyocytes and in an ex vivo Langendorff perfused whole heart model.
RESULTS: Gene delivery of Ang-(1-9) significantly reduced sudden cardiac death post-MI. Pressure–volume measurements revealed complete restoration of end systolic pressure, ejection fraction, end systolic volume and the end diastolic pressure–volume relationship by Ang-(1-9) treatment. Stroke volume and cardiac output were significantly increased versus sham. Histological analysis revealed only mild effects on cardiac hypertrophy and fibrosis, but a significant increase in scar thickness. Direct assessment of Ang-(1-9) on isolated cardiomyocytes demonstrated a positive inotropic effect via increasing calcium transient amplitude and increasing contractility. Ang-(1-9) increased contraction in the Langendorff model through a protein kinase A-dependent mechanism.
CONCLUSIONS: Our novel findings show that Ang-(1-9) gene therapy preserves LV systolic function post-MI, restoring cardiac function. Furthermore, Ang-(1-9) has a direct effect on cardiomyocyte

calcium handling through a protein kinase A-dependent mechanism. These data highlight Ang-(1-9) gene therapy as a potential new strategy in the context of MI

Feasibility study: Magnetic-based passenger localization in train stations
Train stations are a key element of any transport network because they concentrate a large amount of passenger traffic on a daily basis. Passenger localization in train stations is though limited nowadays by the lack of satellite reception indoors and underground. A possible solution could be to use magnetometers, since they are embedded in today’s smartphones and are available in all urban environments. One of the most extended algorithms to perform magnetic localization is magnetic fingerprinting, however magnetic fingerprinting has not yet been proved viable in train stations. The aim of this article is to present a feasibility study of the possibility to apply magnetic fingerprinting in train stations to locate passengers. We have measured and analyzed the magnetic maps of different train stations in Munich, Germany. Our results show that, the functioning of the trains and the electric topology of the stations hinder the passenger localization using magnetic fingerprinting
