This study investigates the relationships between ESL teachers' beliefs about writing instruction and their use of computer technology in the first-year composition classroom. Utilizing a sociocultural approach, the study analyzes the connections between ESL teachers' instructional beliefs and the technological practices that emerge as a result of these beliefs and decisions. Qualitative research was conducted, and data was collected through classroom observations, teacher interviews, and course materials. Data analysis reveals that regardless of teachers' differing beliefs about writing instruction, they use computer technology when it enhances their teaching and students' learning. It also reveals that factors such as teacher attitude …

Weevils are among the most diverse and evolutionarily successful animal lineages on Earth. Their success is driven in part by a structure called the rostrum, which gives weevil heads a characteristic "snout-like" appearance. Nut weevils in the genus Curculio use the rostrum to drill holes into developing fruits and nuts, wherein they deposit their eggs. During oviposition this exceedingly slender structure is bent into a straightened configuration - in some species up to 90° - but does not suffer any damage during this process. The performance of the snout is explained in terms of cuticle biomechanics and rostral curvature, as …

Stable isotopes were measured in the groundwaters of the Salt River Valley basin in central Arizona to explore the utility of stable isotopes for sourcing recharge waters and engineering better well designs. Delta values for the sampled groundwaters range from -7.6‰ to -10‰ in 18O and -60‰ to -91‰ in D and display displacements off the global meteoric water line indicative of surficial evaporation during river transport into the area. Groundwater in the basin is all derived from top-down river recharge; there is no evidence of ancient playa waters even in the playa deposits. The Salt and Verde Rivers are …

Belief affects behavior and rhetoric has the potential to bring about action. This paper is a critical content analysis of the ideology and rhetoric of key Islamist intellectuals and the Islamist organization Hizb ut-Tahrir, as stated on the website http://english.hizbuttahrir.org. The responses of specific Muslim Reformers are also analyzed. The central argument underlying this analysis centers on the notion that such Islamist ideology and its rhetorical delivery could be a significant trigger for the use of violence; interacting with, yet existing independently of, other factors that contribute to violent actions. In this case, a significant aspect of any solution to …

Adolescence is a tumultuous time, and for those with risk factors, it can be even more difficult. This study examined the relationships among intrinsic and extrinsic protective factors such as high self-esteem, high self-efficacy, mattering to others, positive sense of identity, and healthy peer relationships in female adolescents. Additionally, the current study assessed the impact of a positive youth development intervention designed for this particular population. The potential sample consisted of adolescent girls who were students at an alternative high school in the Southwestern region of the United States. Of the 25 girls at the school, 12 participated in the …

In the modern age, where teams consist of people from disparate locations, remote team training is highly desired. Moreover, team members' overlapping schedules force their mentors to focus on individual training instead of team training. Team training is an integral part of collaborative team work. With the advent of modern technologies such as Web 2.0, cloud computing, etc. it is possible to revolutionize the delivery of time-critical team training in varied domains of healthcare military and education. Collaborative Virtual Environments (CVEs), also known as virtual worlds, and the existing worldwide footprint of high speed internet, would make remote team training …

ABSTRACT A cultural overview of the so-called "early music movement" in Arizona, specifically the musicians who performed early music in the mid-to-late twentieth century, has never been undertaken. In applying ethnographic methods to Western art music, Kay Kaufman Shelemay suggests, in her 2001 article, "Toward an Ethnomusicology of the Early Music Movement," that a musical anthropology "would seem to hold great potential for the study of `Western music.'" In this paper I analyze and discuss issues related to "early music" in Arizona from roughly 1960 to 2008. In focusing primarily on the musicians themselves, I address issues in three primary …

Virtual environments are used for many physical rehabilitation and therapy purposes with varying degrees of success. An important feature for a therapy environment is the real-time monitoring of a participants' movement performance. Such monitoring can be used to evaluate the environment in addition to the participant's learning. Methods for monitoring and evaluation include tracking kinematic performance as well as monitoring muscle and brain activities through EMG and EEG technology. This study aims to observe trends in individual participants' motor learning based on changes in kinematic parameters and use those parameters to characterize different types of learners. This information can then …

This research work illustrates the use of software packages based on the concept of nu-merical analysis technique to evaluate the electric field and voltage distribution along composite insulators for system voltages ranging from 138 kV up to 1200 kV ac. A part of the calculations was made using the 3D software package, COULOMB 8.0, based on the concept of Boundary Element Method (BEM). The electric field was calculated under dry and wet conditions. Compo-site insulators experience more electrical stress when compared to porcelain and are also more prone to damage caused by corona activity. The work presented here investigates the …

Previous studies have shown that adequate content knowledge is a necessary, but not sufficient, requirement for affective teaching. While legislation requests teachers to be "highly qualified" in a subject area, such as physics, many teachers are frequently asked to teach in an area when they are not certified through a teaching license to do so. This study uses mixed methods to examine the knowledge of beginning physics teachers. Through semi-structured interviews, classroom observations, and concept maps, the pedagogical content knowledge, subject matter knowledge, and practices of three groups of beginning secondary physics teachers were explored. Data were analyzed qualitatively using …
