The purpose of this quantitative, descriptive study was to identify the self-perceived leadership styles of college academic advisors and to explore the variance in the perceived leadership styles based on demographic information such as academic advising approaches, institutional type, age, years of experience, and gender. Participants were 225 college advisors from among 5,066 members of the National Academic Advising Association (NACADA) during the 2013-2014 academic year who met study criteria and whose email invitation to complete an online survey was presumably delivered, rendering a 4.44% response rate. The Multifactor Leadership Questionnaire Version 5X (MLQ 5X) with five supplemental questions was used for data collection The composite score for leadership style served as the dependent variable, and advising approach, institutional type, age, years of experience, and gender served as the independent variables for the study. Descriptive statistics, frequency distribution, and a factorial analysis of variance (ANOVA) were used for data analysis. The descriptive statistics for this study revealed that college academic advisors represent all points along the entire spectrum of the Full Range Model of Leadership continuum employing different leadership behaviors based on the situation. The descriptive data were supported by the frequency distributions per case which identified transformational leadership as the perceived dominant leadership style for the college academic advisors in this study. A priori to conducting the factorial ANOVA, Leneve’s test for homogeneity of variance indicated a statistically significant coefficient, thus violating the assumption of data normality and rendering the ANOVA findings uninterpretable. An implication of this study is that transformational leadership is the most desired leadership style of the Full Range Model of Leadership for college academic advisors. If this is true, professional development activities for college academic advisors should focus on strengthening transformational leadership behaviors/techniques including with whom and when this leadership style should be employed compared to the other Full Range Model of Leadership styles

Wireless networks are undergoing an unprecedented revolution in the last decade. With the explosion of delay-sensitive applications in the Internet (i.e., online gaming and VoIP), latency becomes a major issue for the development of wireless technology. Taking advantage of the significant decline in memory prices, industrialists equip the network devices with larger buffering capacities to improve the network throughput by limiting packets drops. Over-buffering results in increasing the time that packets spend in the queues and, thus, introducing more latency in networks. This phenomenon is known as “bufferbloat”. While throughput is the dominant performance metric, latency also has a huge impact on user experience not only for real-time applications but also for common applications like web browsing, which is sensitive to latencies in order of hundreds of milliseconds. Concerns have arisen about designing sophisticated queue management schemes to mitigate the effects of such phenomenon. My thesis research aims to solve bufferbloat problem in both traditional half-duplex and cutting-edge full-duplex wireless systems by reducing delay while maximizing wireless links utilization and fairness. Our work shed lights on buffer management algorithms behavior in wireless networks and their ability to reduce latency resulting from excessive queuing delays inside oversized static network buffers without a significant loss in other network metrics. First of all, we address the problem of buffer management in wireless full-duplex networks by using Wireless Queue Management (WQM), which is an active queue management technique for wireless networks. Our solution is based on Relay Full-Duplex MAC (RFD-MAC), an asynchronous media access control protocol designed for relay full-duplexing. Compared to the default case, our solution reduces the end-to-end delay by two orders of magnitude while achieving similar throughput in most of the cases. In the second part of this thesis, we propose a novel design called “LearnQueue” based on reinforcement learning that can effectively control the latency in wireless networks. LearnQueue adapts quickly and intelligently to changes in the wireless environment using a sophisticated reward structure. Testbed results prove that LearnQueue can guarantee low latency while preserving throughput.

In spite of technological advances in wireless systems, transmitted data suffers from impairments through both lossy source coding and transmission overerror prone channels. Due to these errors, the quality of multimedia content is degraded. The major challenge for service providers in this scenario is to measure the perceptual impact of distortions to provide certain Quality of Experience(QoE) to the end user. The general tendency of the Human Visual System (HVS) suggests that the artifacts in the Region-of-Interest (ROI) are perceived to be more annoying compared to the artifacts in Background (BG). With this assumption, the thesis aims to measure the quality of image over ROI and BG independently. Visual Information Fidelity (VIF), a full-reference image quality assessment is chosen for this purpose. Finally, the metric measured over ROI and BG are pooled to get a ROI aware metric. The ROI aware metric is used to predict the Mean Opinion Score (MOS) of an image. In this study, an ROI aware quality metric is used to measure the quality of a set of distorted images generated using a wireless channel. Eventually, MOS of the distorted images is estimated. Lastly, the predicted MOS is validated with the MOS obtained from subjective tests. Testing the proposed image quality assessment approach shows an improved prediction performance of ROI aware quality metric over traditional image quality metrics. It is also observed that the above approach provides a consistent improvement over a wide variety of distortions. After extensive research, the obtained results suggest that the impairments in the ROI are perceived to be more annoying than that of the BG.

Patient satisfaction has been identified as an indicator of quality care. There is no research on patient satisfaction with Nurse Practitioner (NP) care on Guam. Therefore, a cross sectional descriptive study was conducted to assess patient satisfaction with NP care at three primary care clinics on Guam. A convenience sample of patients 18 years and older, seen by an NP were invited to participate in completing the Nurse Practitioner Satisfaction Survey (NPSS). Data collection concluded after a one-month period (N = 108). Descriptive statistics, between group differences, and correlational analyses were conducted. Participation in the survey was voluntary and anonymity, confidentiality, and privacy were ensured. General patient satisfaction was very high for NP care on Guam. "My NP is caring" was the highest scoring item on the NPSS with a mean score of 4.43 (n=56). Participants selected the NP as providing the health education and care the patient found most satisfying. A statistically significant weak negative correlation between patient satisfaction and age and level of injury was found. Singles reported significantly higher patient satisfaction scores than widowers. Study limitations included the small sample size, convenience sampling, social desirability and selection bias. Caring is an essential tenet of NP care and patient satisfaction. Improving NP role clarity is vital to the continued success and growth of the NP profession. The value that NPs bring to primary care is substantiated by the high patient satisfaction levels consistently produced from studies across the globe. In order for NPs to significantly impact the primary care provider shortage all 50 states and the US territories must enact full practice authority (FPA).

The sex-role orientation was determined for 352 high school seniors in Plano, Texas. Using maternal employment status as the independent variable, the students were divided according to full-time employed mothers or full-time homemaker mothers. Results indicated that adolescents of employed mothers had a more liberal sex-role orientation and attitude towards the division of household tasks than adolescents of homemaker mothers. When male and female scores were analyzed separately, the order from most liberal to least liberal was females of employed mothers, females of homemaker mothers, males of employed mothers, and males of homemaker mothers. The mean scores indicated a nontraditional attitude. The study also indicated that maternal happiness with employment did not affect male and female sex-role orientation.

Document representation is important for computer-based text processing. Good document representations must include at least the most salient concepts of the document. Documents exist in a multidimensional space that difficult the identification of what concepts to include. A current problem is to measure the effectiveness of the different strategies that have been proposed to accomplish this task. As a contribution towards this goal, this dissertation studied the visual inter-document relationship in a dimensionally reduced space. The same treatment was done on full text and on three document representations. Two of the representations were based on the assumption that the salient features in a document set follow the chi-distribution in the whole document set. The third document representation identified features through a novel method. A Coefficient of Variability was calculated by normalizing the Cartesian distance of the discriminating value in the relevant and the non-relevant document subsets. Also, the local dictionary method was used. Cosine similarity values measured the inter-document distance in the information space and formed a matrix to serve as input to the Multi-Dimensional Scale (MDS) procedure. A Precision-Recall procedure was averaged across all treatments to statistically compare them. Treatments were not found to be statistically the same and the null hypotheses were rejected.

In contrast with traditional extended depth-of-field approaches, we propose a depth-based deconvolution technique that realizes the depth-variant nature of the point spread function of an ordinary fixed-focus camera. The developed technique brings a single blurred image to focus at different depth planes which can be stitched together based on a depth map to output a full-focus image. Strategies to suppress the deconvolution's ringing artifacts are implemented on three levels: block tiling to eliminate boundary artifacts, reference maps to reduce ringing initiated by sharp edges, and depth-based masking to mitigate artifacts raised by neighboring depth-transition surfaces. The performance is validated numerically for planar and multidepth objects. (C) 2016 Society of Photo-Optical Instrumentation Engineers (SPIE)

Financial markets are nowadays more important than ever. Financial crisis of the previous decade demonstrated their power to influence stability of the whole economy. Since the consensus blames weak regulation and considers the only solution to be its extension, this thesis tries to provide the proof of existence of other options. The focus is firstly aimed at the weaknesses of the fractional reserve banking, which does not follow the basic legal principles of a deposit contract. This practice results in price fluctuations and favoritism of first takers of newly created money. Moreover, the thesis develops a new method of analysis, which emphasizes the application of preferences in exchanges. Important outcome of this method is the demonstration that the public does not have to always prefer the most evolved form of institution. All institutions within commercial banks are then analyzed with the use of this method and the thesis shows where preference channels are being interfered with. This analysis also reveals another outcome of fractional reserve banking, which is that the newly created money is only used according to the preferences of commercial bankers. We suggest that circumvention of the true nature of a deposit contract leads to a similar outcome in loan banking, where funds gathered by loan...

This diploma thesis deals with the crucial impact of the neutral vowel schwa on creating prominence contrasts in English pronunciation teaching, i.e. a schwa-centred approach. The theoretical part focuses on the complex description of the target sound with regard to the suprasegmental level, including Czech speakers' difficulties to recognise and pronounce this vowel and prominence patterns it participates in. Furthermore, it defines the essence of the schwa-centred approach. The practical part presents the implementation of the schwa-centred approach in teaching practice in the form of a set of activities aimed at perception, production and raising students' awareness of this phenomenon. The effectiveness of the activities is evaluated by means of the analysis of audio recordings made before and after the teaching and assessment of students' questionnaires. The thesis also contains all worksheets with task descriptions applying the schwa-centred approach. KEY WORDS schwa, full vowel, prominence contrasts, perception, production, raising awareness

In the present work we study the existence a properties of solution of the system of partial differential equations describing steady flow of Newtonian fluid. We consider that this system has anisotropic dissipative potential. We prove existence of weak solution to this system and its partial C1,α -regularity in 3D and full C1,α -regularity in 2D. 1
