Estimates of Use of Research-Based Instructional Strategies in Core Electrical or Computer Engineering Courses

Many research-based instruction strategies (RBISs) have been developed; their superior efficacy with respect to student learning has been demonstrated in many studies. Collecting and interpreting evidence about: 1) the extent to which electrical and computer engineering (ECE) faculty members are using RBISs in core, required engineering science courses, and 2) concerns that they express about using them, are important aspects of understanding how engineering education is evolving. The authors surveyed ECE faculty members, asking about their awareness and use of selected RBISs. The survey also asked what concerns ECE faculty members had about using RBISs. Respondent data showed that awareness of RBISs was very high, but estimates of use of RBISs, based on survey data, varied from 10% to 70%, depending on characteristics of the strategy. The most significant concern was the amount of class time that using an RBIS might take; efforts to increase use of RBISs must address this.

Contemporary Hollywood And The Attention Economy

This thesis had two goals: to explore the transformation of Hollywood from the 1930s to present, and to investigate how Contemporary Hollywood functions in a growing attention economy. Evident in the types of films that it produces as well as its evolving industrial structure, Contemporary Hollywood significantly differs from the Classical Hollywood of the 1930s. New digital technologies like surround sound and computer-generated imagery (CGI) have allowed studios to create a different type of film like the blockbuster and to have more extensive control over their films. Additionally, growing exhibition and distribution platforms have also fundamentally altered the industrial landscape of Hollywood. In order to combat this more egalitarian distribution system, Contemporary Hollywood has turned to conglomeratization. But, what has caused such a radical shift in the form and function of Contemporary Hollywood and its films? This thesis argues that Hollywood is failing to thrive in this new media landscape¿not because of changing technologies¿but because of a changing consumer. Richard Lanham theorizes that we are living in a growing attention economy, where human attention is the most valuable commodity in such an information-saturated society. For the current consumer, there is near-constant media over-stimulation: he or she is exposed to any number of screens (mobile phones, laptops, tablets, televisions, etc.) at any given time. Because we can access anything from anywhere at anytime, we¿ve become somewhat schizophrenic and impatient in terms of the media that we consume in our lives.

Static and Dynamic Error Correction of a Computer-Aided Mechanical Navigation Linkage for Arthroscopic Hip Surgery

While beneficially decreasing the necessary incision size, arthroscopic hip surgery increases the surgical complexity due to loss of joint visibility. To ease such difficulty, a computer-aided mechanical navigation system was developed to present the location of the surgical tool relative to the patient¿s hip joint. A preliminary study reduced the position error of the tracking linkage with limited static testing trials. In this study, a correction method, including a rotational correction factor and a length correction function, was developed through more in-depth static testing. The developed correction method was then applied to additional static and dynamic testing trials to evaluate its effectiveness. For static testing, the position error decreased from an average of 0.384 inches to 0.153 inches, with an error reduction of 60.5%. Three parameters utilized to quantify error reduction of dynamic testing did not show consistent results. The vertex coordinates achieved 29.4% of error reduction, yet with large variation in the upper vertex. The triangular area error was reduced by 5.37%, however inconsistent among all five dynamic trials. Error of vertex angles increased, indicating a shape torsion using the developed correction method. While the established correction method effectively and consistently reduced position error in static testing, it did not present consistent results in dynamic trials. More dynamic paramters should be explored to quantify error reduction of dynamic testing, and more in-depth dynamic testing methodology should be conducted to further improve the accuracy of the computer-aided nagivation system.
