The Beijing-Arizona Sky Survey (BASS) is a new wide-field legacy imaging survey in the northern Galactic cap using the 2.3 m Bok telescope. The survey will cover about 5400 deg(2) in the g and r bands, and the expected 5 sigma depths (corrected for the Galactic extinction) in these two bands are g = 24.0 and r = 23.4 mag (AB magnitude). BASS started observations in 2015 January. and had. completed about 41% of the. area as of 2016 July. The first data release contains calibrated images obtained in 2015 and 2016 and their corresponding single-epoch. and coadded catalogs. The actual depths of the. single-epoch images are g similar to 23.4 and r similar to 22.9 mag. The full depths of the. three epochs are g similar to 24.1 and r similar to 23.5 mag.

Texto completoResumen
Although the primary role of the computer has been in processing and analysis of survey data, it has increasingly been used in data collection. Computer surveys are not exempt from a common problem: some refuse to participate. Many researchers and practitioners indicate the refusal problem is less for computer surveys, perhaps due to the novelty of the method. What has not been investigated is the refusal problem when on-line surveys are no longer novel. This research study examines the use of one form of computer-assisted data collection, the electronic or on-line survey, as an organizational research tool. The study utilized historical response data and administered an on-line survey to individuals known to be cooperative or uncooperative in other on-line surveys. It investigated nonresponse bias and response effects of typical responders, periodic participants, and typical refusers within a sample of corporate employees in a computer-interactive interviewing environment utilizing on-line surveys. The items measured included: participation, respondent characteristics, response speed, interview length, perceived versus actual interview length, quantity of data, item nonresponse, item response bias, consistency of response, extremity of response, and early and late response. It also evaluated factors reported as important when deciding to participate, preferred data collection method, and preferred time of display. Past participation, attitudes toward on-line organizational surveys, response burden, and response error were assessed. The overall completion rate of 55.7% was achieved in this study. All effort was made to encourage cooperation of all groups, including an invitation to participate, token, on-line pre-notification, 800 number support, two on-line reminders, support of temporary exit, and a paper follow-up survey. A significant difference in the participation of the three groups was found. Only three demographic variables were found to be significant. No significant differences were found in speed of response, interview length, quantity, item nonresponse, item response bias, consistency, and extremity. Significant differences were found in the perceived and actual times to complete the survey.

Texto completoResumen
The performance of radar detection and imaging systems strongly depends on the characteristics of radar clutter. In order to improve the radar signal processing algorithms, successful analysis and modeling of radar clutter are required. For a successful model of radar clutter, both the spectral and statistical characteristics of the clutter should be revealed. Within the scope of this study, an experimental radar data acquisition system is established to analyze radar clutter. The hardware and the data processing system are first verified using generic signals and then a set of measurements is taken in the open terrain. In this thesis, the limitations and problems encountered during the establishment of the system are explained in detail. The spectral and statistical analyses performed on the recorded data are examined. The temporal
and spatial behavior of the measured clutter data are explored. The hypothetical models proposed so far in the literature are tested on the experimental data and the fitting of models to the experimental data is confirmed using various goodness-of-fit tests. Finally, the results of the analyses are interpreted in the light of the radar system parameters and the characteristics of the illuminated terrain.

The distribution of real-time multimedia streams is seen nowadays as the next step forward for the Internet. One of the most obvious uses of such streams is to support telephony over the Internet, replacing and improving traditional telephony. This thesis investigates the development and deployment of services in two Internet telephony environments, namely CINEMA (Columbia InterNet Extensible Multimedia Architecture) and VOCAL (Vovida Open Communication Application Library), both based on the Session Initiation Protocol (SIP) and open-sourced. A classification of services is proposed, which divides services into two large groups: basic and advanced services. Basic services are services such as making point-to-point calls, registering with the server and making calls via the server. Any other service is considered an advanced service. Advanced services are defined by four categories: Call Related, Interactive, Internetworking and Hybrid. New services were implemented for the Call Related, Interactive and Internetworking categories. First, features involving call blocking, call screening and missed calls were implemented in the two environments in order to investigate Call-related services. Next, a notification feature was implemented in both environments in order to investigate Interactive services. Finally, a translator between MGCP and SIP was developed to investigate an Internetworking service in the VOCAL environment. The practical implementation of the new features just described was used to answer questions about the location of the services, as well as the level of required expertise and the ease or difficulty experienced in creating services in each of the two environments.<br>KMBT_363<br>Adobe Acrobat 9.54 Paper Capture Plug-in

Texto completoResumen
Sample surveys are often used to collect data for obtaining estimates of finite population quantities, such as disease prevalence. However, non-response and sampling frame under-coverage can cause the survey sample to differ from the target population in important ways. To reduce bias in the survey estimates that can arise from these differences, auxiliary information about the target population from sources including administrative files or census data can be used. Survey weighting is one approach commonly used to reduce bias. Although weighted estimates are relatively easy to obtain, they can be inefficient in the presence of highly dispersed weights. Model-based estimation in survey research offers advantages of improved efficiency in the presence of sparse data and highly variable weights. However, these models can be subject to model misspecification. In this dissertation, we propose Bayesian penalized spline regression models for survey inference about proportions in the entire population as well as in sub-populations. The proposed methods incorporate survey weights as covariates using a penalized spline to protect against model misspecification. We show by simulations that the proposed methods perform well, yielding efficient estimates of population proportion for binary survey data in the presence of highly dispersed weights and robust to model misspecification for survey outcomes. We illustrate the use of the proposed methods to estimate the prevalence of lifetime temper dysregulation disorder among National Guard service members overall and in sub-populations defined by gender and race using the Ohio Army National Guard Mental Health Initiative 2008-2009 survey data. We further extend the proposed framework to the setting where individual auxiliary data for the population are not available and utilize a Bayesian bootstrap approach to complete model-based estimation of current and undiagnosed depression in Hispanics/Latinos of different national backgrounds from the 2015 Washington Heights Community Survey.

Texto completoResumen
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2015<br>Three new methods for determining the structural index and source distance for magnetic field data are presented. These methods require only the calculation of the first and second order analytic signal amplitudes of the total field and are applicable to both profile and gridded data. The three methods are first tested on synthetic data and then on two real datasets to test for applicability and repeatability. It was found that each method had different strengths and weaknesses and thus one method cannot be favoured over the others. Cooper (2014) describes how to calculate the distance to source over both profile and gridded data given a user defined structural index. Often however, particularly in the case of real data, the structural index is not known or varies over the surveyed area. These three new methods however do not require any user input since the structural index is calculated thus making them more applicable to regions of unknown geology. It was found that the first of the three new methods, the multi-distance inversion method, was best used as an edge-detection filter, since the use of higher order derivatives resulted in increased noise levels in the distance to source calculation. The third of these new methods, the unconstrained inversion method, discussed in Chapter 7, not only solves for the structural index but also determines the depth of the source. In that particular case, the structural index is used as a rejection filter, whereby, depth solutions associated with structural index values outside of the expected range are deemed to be invalid. Unlike the third new method, the first two methods require the distance to source to be calculated via the approach described by Cooper (2014) (which requires the user to define the structural index), the results of which are later rescaled by the calculated structural index to yield what is termed a rescaled distance to source. All three of the new methods are fully automatic and require no user control.
The techniques were first tested on both profile and gridded theoretical data over sources with known structural index values. All of the methods were able to estimate the structural index of each of the particular sources and give depth estimates that varied from the true depth by less than 20 percent (with deeper sources being more inaccurate). Noise was also added to the theoretical data in an attempt to assess how the methods can be expected to perform with real data. It was found that when applied to noisy data, these methods performed equally well to slightly worse, than when the method developed by Cooper (2014) was used.
As a real world case study these three new methods were tested on aeromagnetic data collected over the Kuruman Military Area, Northern Cape, South Africa. Regional deformations as well as later intrusive dykes and cross cutting faults were imaged by the chosen depth determination procedures. The dolerite dykes in the area were found to occur between 20 to 60 m deep. While the sand cover was estimated to be between 30 to 40 m thick. Overall, the techniques yield distance to source estimates that differ by less than 15 m, over sources, to the results obtained by using the source distance method (Cooper, 2014). To test for repeatability a second aeromagnetic dataset, collected over a dyke swarm within the Bushveld Complex, South Africa was considered. Again comparable (less than 15 m over sources) depth estimates were made between the unconstrained and constrained inversions. Since the distance to source estimates produced by these new unconstrained inversion methods are comparable to those produced by constrained inversion (Cooper, 2014) the project can be deemed successful.

Indiana University-Purdue University Indianapolis (IUPUI)<br>Caring relationships established between nurse managers and staff nurses promote positive work environments. However, research about staff nurses' perceptions of nurse manager caring behaviors is limited. A 94-item Caring Assessment Tool-Administration (CAT-adm©) was developed to measure staff nurses' perceptions of nurse managers' caring behaviors; however, it lacked robust psychometric testing. This study was undertaken to establish the CAT-adm© survey as a reliable and valid tool to measure staff nurses' perceptions of nurse managers' caring behaviors.
The Quality-Caring Model® (QCM®) served as the theoretical framework. Specific aims were to 1) evaluate construct validity of the CAT-adm© survey by describing factors that account for variance in staff nurses' perceptions of nurse manager caring, 2) estimate internal consistency, and 3) conduct item reduction analysis. Four research questions were: 1) Will the factor structure of observed data fit an 8-factor solution? 2) What is the internal consistency reliability of the CAT- adm©? 3) What items can be reduced while maintaining an acceptable factor structure? and 4) What are staff nurses' perceptions of nurse manager caring behaviors?
A cross-sectional descriptive design was used. A sample of 703 staff nurses from Midwestern, Midatlantic and Southern Regions of the U.S. completed the CAT-adm© survey electronically. Analysis included Confirmatory Factor Analysis (CFA), Exploratory Factor Analysis (EFA), univariate analysis, and descriptive statistics. CFA did not support an 8-factor solution. EFA supported a two-factor solution and demonstrated significant shared variance between the two factors. This shared variance supported a one-factor solution that could conceptually be labeled Caring Behaviors. Random selection reduced the scale to 25-items while maintaining a Cronbach's Alpha of .98. Using the new 25-item scale, the composite score mean of staff nurses' perceptions of nurse manager caring behaviors indicated a moderately high level of caring. Suggestions for nursing administration, nurse manager practice, leadership, education and for future research were given.
The new 25-item CAT-adm© survey has acceptable reliability and validity. The 25-item CAT-adm© survey provides hospital administrators, nurse managers, and researchers with an instrument to collect valuable information about the caring behaviors used by nurse managers in relationship with staff nurses.

The work is concerned with preparing exercises for the teaching of bulk data processing in the environment of a spreadsheet program. The exercises can be used in the lessons of ICT in the upper stage of the elementary school and in secondary schools. Presently a lot of exercises exist. These exercises are based on obsolete or uninteresting data or directly on artificial data. On the contrary there are few exercises which are based on up to date data or on data which the students entered. In the work there is an emphasis on the importance of creating exercises which are based on up to date data which is freely accessible on the Internet. For example geographical, economic or meteorological data. A software application which can download this data and transfer it into a suited format for further use in a spreadsheet program is a part of the work. We can note the benefit of using exercises, where data has been entered by the students of the class. A part of the work is a software solution which makes a survey possible for the teacher. The students answer the questions in the survey via a form. These answers are worked up into a table for further use in the lessons. An important part of the work is a set of methodical sheets. These sheets contain topics for exercises, which are specialized in bulk data processing. They show acceptable elaboration of downloaded or measured data and possible interpretation of the results. The main objective of the work is to show how and where to get up to date and attractive data for the teaching of bulk data processing and how to use it. The software and the methodical sheets should contribute to this.

Texto completoResumen
O conhecimento do fundo marinho é um fator crucial para a segurança da navegação, assim como para as diversas atividades marítimas. O progresso da hidrografia tem mostrado novos horizontes trazendo diversos sistemas complexos que prometem resolver muitos dos desafios nesta área.
Respetivamente à aquisição de dados batimétricos através de sondadores de feixe-simples, este trabalho surge da necessidade de colmatar os erros dependentes do fator humano, reduzir o tempo de processamento e melhorar a qualidade do mesmo. Para tal, são necessárias ferramentas computacionais que auxiliem a fase de processamento de dados e a elaboração de produtos finais.
Deste modo, foi criada uma ferramenta, com auxílio a vários algoritmos e métodos desenvolvidos. Um dos utilizados é o Self Organizing Map (SOM) ou mapas auto-organizados. O estudo apresenta, sinteticamente, conceitos básicos de Levantamentos Hidrográficos para uma melhor compreensão dos dados analisados. De seguida, apresenta-se o modo de funcionamento do algoritmo SOM, abordando aspetos necessários para a realização de agrupamento de dados (clustering) como parte da solução da ferramenta desenvolvida. A partir deste, apresenta-se a metodologia desenvolvida para a realização da seleção de dados (sondas) necessária à criação de produtos para representação do fundo marinho. A ferramenta desenvolvida, Processamento de Dados Garmin com Self-Organizing Map (PDGSOM), é confrontada com outros sistemas de processamento de dados batimétricos, nomeadamente o software CARIS. Deste modo, comparando modelos batimétricos realizou-se uma análise de parâmetros de funcionamento e eficácia da ferramenta desenvolvida.
Em síntese, a presente dissertação tem como objetivo a construção de uma ferramenta com uma interface de fácil utilização, fornecendo uma informação segura na utilização dos dados e produtos obtidos, tendo como motivo de estudo a “segurança na navegação”.<br>The need of knowledge of the seabed in its whole, has been brought many challenges to maritime navigation. The safety of navigation is a crucial factor, and even with all the progress and the new horizons that hydrography science has shown with its numerous complex systems, there are still many obstacles to overcome.
Regarding the acquisition of bathymetric data with single beam echo sounder, this work arises from the need to bridge the errors reflected on the human factor, improve the processing of data acquisition and time reduction. For all the reasons stated above, computational tools are of a main importance on the data processing phase and the elaboration of final products.
For this study, I developed a tool, using Decision Support System, based on the algorithm of self-organizing map Kohonen. Better known for its clustering, visualization and classification capabilities with comprehensive solutions for selection of bathymetric data.
The study begins by presenting, the basic concepts for a better understanding of the studied area, with respect to the Hydrographic Surveys. Next, the operation of the Self Organizing Map algorithm is presented, addressing aspects necessary to perform data grouping (clustering) as part of the solution of the developed tool. From this, I present the methodology used to develop the realization of data selection necessary to create products for representing the seabed. The developed tool, Garmin Data Processing with Self-Organizing Map (PDGSOM - Portuguese version) is compared with other bathymetric data processing systems, CARIS software. This allowed the comparison of digital elevation models, analysis of operation parameters and effectiveness of the developed tool.
Succinctly, this dissertation has as main goal the construction of a tool with an easy-use interface, providing safe information in the use of the data and obtained products, based on the principles of "safety of navigation ".

Texto completoResumen
The vegetation of the Nooitgedacht section of the Loskop Dam Nature Reserve resembles
Bankenveld vegetation and differs from the other areas of the reserve. This study was
undertaken to identify, classify, and describe the plant communities present on this section,
and to determine their veld condition. The Braun-Blanquet approach was followed to classify
the different plant communities. A total number of 170 sample plots (100m2) were placed in
all homogeneous vegetation units in a randomly stratified basis. The Ecological Index
Method (EIM) was used to determine the veld condition. Data were collected using the steppoint
method and incorporated into the GRAZE model from where the veld condition was
calculated. A minimum of 400 step points were surveyed in each community with more
points in the larger communities. Plant community data was analysed using the JUICE
software program. A total of 11 plant communities were identified. The overall veld condition
score indicates the vegetation to be in a good condition, resulting in a high grazing capacity.<br>Environmental Sciences<br>M. Sc. (Nature Conservation)
