Description
Growing popularity of alternatively certifying teachers has created challenges for teacher preparation programs. Many non-traditional routes into classroom include no full-time mentor teacher. Absence of a mentor teacher in the classroom leaves teachers with a deficit. This study follows ten teachers on the intern certificate enrolled in both an alternative certification teacher preparation program and the Teach for America organization as they pursue a master's degree in education and state teaching certification from a large southwestern university. The five randomly chosen for the treatment group and the control group contained 1 male and 4 female teachers, some of whom teach at public schools and others at charter schools. All were secondary education language arts teachers ranging in age from 22- 29. The treatment used in this study is a job-embedded, professional development, software tool designed to help teachers track their classroom practices called MyiLOGS. The purpose of this action research project was to study the effect using MyiLOGS had on six of the nine areas evaluated by a modified version of the Teacher Advancement Program evaluation rubric, alignment with Opportunity To Learn constructs, and the tool's influence on the efficacy of these first year teachers. The data generated from this study indicate that the MyiLOGS tool did have a positive effect on the teachers' TAP evaluation performances. Also, the MyiLOGS tool had a large impact on the teachers' instruction as measured by the constructs of Opportunity to Learn and their teaching self-efficacy. Implications suggested the tool was an asset to these teachers because they tracked their data, became more reflective, and self-sufficient.

Description
The theory of learning centered academic advising states that the purpose of advising is to teach undergraduate students about the logic and purpose of their education. Previous scholarship on learning centered advising has focused on the theoretical or on implementation by faculty at small colleges and universities. Methods for supporting learning centered advising in other contexts are lacking. This mixed methods, action research study investigates the efficacy of FaculTea, a professional development program designed to promote learning centered advising practices among professional academic advisors at a large state university. The study also measured frequency of learning centered advising and student perceptions of learning centered advising. Participants were 57 academic advisors in a liberal arts and sciences college at a large state university, who reported on their advising practices. In addition, the investigator interviewed four advisors, and observed them during 15 advising appointments. Also, six students were interviewed to determine their response to learning centered academic advising. Results showed the FaculTea program model was effective in promoting learning centered advising. In addition, advisors used learning centered advising to a moderate extent, depending upon the context of the appointment, the developmental level of the student, and experience level of the advisor. Student responses varied. These findings suggest learning centered advising can be incorporated into various academic advising contexts and structures and that FaculTea is an excellent model for learning centered academic advisor professional development.

Description
The rise in the number of students found to have autism has been staggering over the past ten years. Accommodating these students effectively and appropriately in a public school is a challenge many teachers are deemed with, sometimes without adequate training. This study was aimed at affecting the underlying social misunderstandings inherent to students with Autism Spectrum Disorder and an at-risk general education peer through a comprehensive intervention consisting of peer mentoring, interactive social stories and video modeling strategies. Observations, student interviews, vignettes and student and researcher journals served as data sources. Three fourth grade boys, including a student with autism, a peer with behavioral concerns and a model peer, participated in an intervention designed using a multiple baseline across behaviors. The target students, including the student with autism and the peer with behavioral concerns increased their ability to demonstrate three distinctive skills, attending to task, raising hand and academic responding. Analysis of the data also showed an overall increase in levels of engagement and motivation. Strong friendships developed among all three participants. Implications suggest that a comprehensive approach is effective in reducing unwanted social behaviors and promoting positive social skills and gives further insight into the target students' motivation.

Description
In accordance with the Principal Agent Theory, Property Right Theory, Incentive Theory, and Human Capital Theory, firms face agency problems due to “separation of ownership and management”, which call for effective corporate governance. Ownership structure is a core element of the corporate governance. The differences in ownership structures thus may result in differential incentives in governance through the selection of senior management and in the design of senior management compensation system. This thesis investigates four firms with four different types of ownership structures: a public listed firm with the controlling interest by the state, a public listed firm with a non-state-owned controlling interest, a public listed firm a family-owned controlling interest, and a Sino-foreign joint venture firm. By using a case study approach, I focus on two dimensions of ownership structure characteristics – ownership diversification and differences in property rights so as to document whether there are systematic differences in governance participation and executive compensation design. Specifically, I focused on whether such differences are reflected in management selection (which is linked to adverse selection and moral hazard problems) and in compensation design (the choices of performance measurements, performance pay, and in stock option or restricted stock). The results are consistent with my expectation – the nature of ownership structure does affect senior management compensation design. Policy implications are discussed accordingly.

Description
Arcadia Elementary School is an urban Title 1 school that serves 800 students in kindergarten through eighth grade. The school uses a commercial program called Make Your Day to manage student behavior. This program, aligned to the tenets of Positive Behavior Interventions and Supports (PBIS), meets the needs of most students but not the most frequent classroom disruptors. This mixed methods participatory action research study explores the how an understanding of a frequently disruptive student's ecology can lead to more effective support and improved behavioral outcomes. The Behavior Intervention Team process consists of effective data tracking tools and practices and a team-based, data-driven approach to student behavior analysis and is a model for how urban schools can leverage existing resources to better support disruptive students.

Description
Historically, institutions of higher education focused their efforts on programs and services to support traditional students' integration (i.e., the eighteen year old who enrolls in college immediately after graduating from high school) into the college environment. Integration into the university environment contributes to student retention. Underrepresented students, specifically community college transfer students, are left out of the retention planning process. With the increase of transfer students transitioning to four-year universities, this study explored transfer students' integration experience within their initial six weeks of attendance at a receiving institution. This action research study implemented an E-Mentoring Program utilizing the social media platform, Facebook. Results from the mixed-methods study provided evidence that classroom connection interwoven with social rapport with peers, cognizance of new environment, and institutional and peer resources matter for integration within the first six weeks at HUC (a pseudonym). The information gained will be used to inform higher education administrators, student affairs practitioners, faculty, and staff as they develop relevant services, programs, and practices that intentionally support transfer students' integration.

Description
This study reviews the effectiveness of a faculty development program to prepare faculty members in the health related fields to design and develop flipped and blended learning courses. The FAB Tech workshop focuses on flipped and blended learning technologies as a method to increase the use of active learning in the classroom. A pre/posttest was administered to the participants on their use of technology and their course delivery strategies. In addition, interviews were conducted with a purposeful sample of the participants based on level of engagement in the workshop and their change in the pre/posttest. The program was effective in increasing the use of technological tools and their purposeful integration into courses. However, faculty workload and institutional support issue served as barriers to overcome. The findings of this study will help address how to over come some of these barriers and to develop more effective faculty development programs that encourage the use of flipped and blended learning.

Description
The occupation of policing has long been associated with masculinity. Resistance
to the integration of women into the law enforcement profession stemmed from widely
held beliefs that women were incapable of performing the police function. Although
much has changed in policing, female officers are bombarded with masculine symbols
depicting mostly the agentic characteristics associated with the law enforcement
profession. Or, they are offered socially and culturally constructed definitions of who
they are supposed to be as women as well as what is lacking in them as officers. This
study explores the disparity between how female police officers are viewed, what they
experience, and how they are represented. The perspective of the female officer was
captured, and presented through visual images obtained by participants. Descriptive
coding and thematic analysis converted photographs and written narratives into
participant generated themes and stories. Female officers in this study resisted stereotypic
portraits of women in policing and sought expanded boundaries of inclusion within their
profession. Participants produced some understanding of how women construct their
personal and professional identities relative to gender, as well as the larger roles of
women in society.

Description
Effectively educating students with autism is a necessary element in providing all students with a free and appropriate public education, and as the number of students diagnosed with an autism spectrum disorder continues to increase in both public and private educational settings, providing successful and satisfactory professional development opportunities in the area of autism is becoming increasingly essential. This study explored the experiences of twenty-three educators in a suburban southwest K-12 public school district, as they participated in a fifteen-hour professional development course in an online or face-to-face format, and collaboratively problem-solved their challenges in educating students with autism. Qualitative data was collected from participants' weekly written reflections and comments from a pre- and post-survey on attitudes, to determine quality of and satisfaction with collaboration in relation to course format. Results indicated that the online format produced higher-quality collaboration when it came to presenting one's own situation(s) to the group, finding group discussions helpful, having enough time to collaborate, providing feedback/suggestions to group members, and perceiving suggestions for one's own situation as helpful (as evidenced by the number of suggestions that participants said they would likely implement). The face-to-face format produced higher-quality collaboration when it came to in-depth problem-solving regarding a situation, implementing suggestions for one's own situation, and relating course content to collaborative activities. Participants' attitudes about using technology as a means of collaboration showed little change overall from pre- to post-survey. Though slight increases in positive attitudes concerning technology were found in various areas, many participants still thought highly of a face-to-face format for collaborative purposes, even after participating in the online professional development course. Findings may be of use to educational institutions developing online or face-to-face professional development opportunities in the area of autism.

Description
The theme for this work is the development of fast numerical algorithms for sparse optimization as well as their applications in medical imaging and source localization using sensor array processing. Due to the recently proposed theory of Compressive Sensing (CS), the $\ell_1$ minimization problem attracts more attention for its ability to exploit sparsity. Traditional interior point methods encounter difficulties in computation for solving the CS applications. In the first part of this work, a fast algorithm based on the augmented Lagrangian method for solving the large-scale TV-$\ell_1$ regularized inverse problem is proposed. Specifically, by taking advantage of the separable structure, the original problem can be approximated via the sum of a series of simple functions with closed form solutions. A preconditioner for solving the block Toeplitz with Toeplitz block (BTTB) linear system is proposed to accelerate the computation. An in-depth discussion on the rate of convergence and the optimal parameter selection criteria is given. Numerical experiments are used to test the performance and the robustness of the proposed algorithm to a wide range of parameter values. Applications of the algorithm in magnetic resonance (MR) imaging and a comparison with other existing methods are included. The second part of this work is the application of the TV-$\ell_1$ model in source localization using sensor arrays. The array output is reformulated into a sparse waveform via an over-complete basis and study the $\ell_p$-norm properties in detecting the sparsity. An algorithm is proposed for minimizing a non-convex problem. According to the results of numerical experiments, the proposed algorithm with the aid of the $\ell_p$-norm can resolve closely distributed sources with higher accuracy than other existing methods.
