Implementation of the Middle School Concept: a Profile of Perceived Effects

Implementation of the Middle School Concept: a Profile of Perceived Effects

Date: December 1994
Creator: Hartin, Gail Bantle
Description: This study addressed the perceptions of teachers, parents, and students in a suburban middle school about the effects of implementation of the middle school concept on instruction, peer group interaction, teacher attitudes and practices, and school culture. A qualitative approach was used for this study. Interview questions were developed to determine perceptions about effects in the areas identified in the research questions. Interviews were conducted with selected teachers, parents, and students who had exposure to the school before and after planned changes were implemented. Documents were examined for evidence of perceptions in the four areas identified. In addition, an existing data set (a student survey} was examined and the same survey was administered to a more recent group of students to identify possible patterns in student perceptions.

The Implementation of Transition from Spanish Reading to English Reading Programs in Bilingual Classrooms

The Implementation of Transition from Spanish Reading to English Reading Programs in Bilingual Classrooms

Date: December 1994
Creator: Amaya, Jesús, 1956-
Description: The purpose of this study was to describe the actual implementation of the transition process as observed in bilingual classrooms, and in particular, to examine the critical components (policy, curricular, and instructional characteristics) of the Spanish-to-English reading transition policies implemented in bilingual education programs in elementary schools in the Denton Independent School District in Texas. Four research questions drove this study. To investigate these questions, a multidimensional, descriptive research design was employed. The researcher used questionnaires, interviews, and field observations. The 11 educators, 6 bilingual teachers, 2 school-site principals, 2 school-site coordinators, and 1 district bilingual coordinator, were asked several types of questions (open response and closed response) using different types of instruments (questionnaires and interviews). Also, the six bilingual teachers were observed using two types of instruments (field notes and video tapes).

Implementation of Turbo Codes on GNU Radio

Implementation of Turbo Codes on GNU Radio

Date: December 2010
Creator: Talasila, Mahendra
Description: This thesis investigates the design and implementation of turbo codes over the GNU radio. The turbo codes is a class of iterative channel codes which demonstrates strong capability for error correction. A software defined radio (SDR) is a communication system which can implement different modulation schemes and tune to any frequency band by means of software that can control the programmable hardware. SDR utilizes the general purpose computer to perform certain signal processing techniques. We implement a turbo coding system using the Universal Software Radio Peripheral (USRP), a widely used SDR platform from Ettus. Detail configuration and performance comparison are also provided in this research.

Implementation of Wireless Communications on Gnu Radio

Implementation of Wireless Communications on Gnu Radio

Date: May 2012
Creator: Njoki, Simon M.
Description: This thesis investigates the design and implementation of wireless communication system over the GNU Radio. Wireless applications are on the rise with advent of new devices, therefore there is a need to transfer the hardware complexity to software. This development enables software radio function with minimum hardware dependency. the purpose of this thesis is to design a system that will transmit compressed data via Software Defined Radio (SDR). Some parameters such as modulation scheme, bit rate can be changed to achieve the desired quality of service. in this thesis GNU (GNU’s not unix) radio is used while the hardware structure is Universal Software Radio Peripheral (USRP). in order to accomplish the goal, a compression technique called H264 (MPEG_4) encoding is applied for converting data into compressed format. the encoder was implemented in C++ to get compressed data. After encoding, the transmitter reads the compressed data and starts modulation. After modulation, the transmitter put the packets into USRP and sends it to the receiver. Once packets are received they are demodulated and then decoded to recover the original data.

Implementing a Physical Activity Centered Education Program for Individuals with Brain Injury

Implementing a Physical Activity Centered Education Program for Individuals with Brain Injury

Date: May 2012
Creator: Woolsey, Anne-Lorraine T.
Description: Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, education-based PA curriculum is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in services provided. Consequently, the purpose of this study was to create and deliver a physical activity centered education (PACE) program that supplemented the existing rehabilitation program for brain injury. PACE consists of an 8-week (16 session) program aimed to (1) increase self-efficacy for being physically active of PACE program participants, (2) increase PA stage of change in PACE program participants or the maintenance of adequate level of PA, and (3) improve the rehabilitation outcomes (i.e., abilities, participation, adjustment) of PACE program participants. Based on previous research, it is hypothesized that participation in PACE will result in (1A) increased self-efficacy for PA, (1B) greater self-efficacy for PA than the standard of care group, (2A) increased readiness to be physically active, (2B) greater readiness to change their PA behavior than the standard of care group, (3A) improved rehabilitation outcomes, and (3B) greater rehabilitation outcomes than the standard of care group. the PACE ...

The implications of national culture on American knowledge work teams: A model of a collaborative corporate culture to support team functioning

The implications of national culture on American knowledge work teams: A model of a collaborative corporate culture to support team functioning

Date: December 1999
Creator: Bussey, Jennifer Amy
Description: In order to remain competitive, many American businesses implement team-based work strategies. In many cases, however, teams fail in American organizations, which may be in part due to a conflict between American culture and the cooperative environment necessary for teams to function effectively. By comparing the literature regarding American culture, challenges faced by teams, and then corporate culture, it becomes evident that there are aspects of American culture that pose challenges but also that an appropriate corporate culture can mediate some areas of incompatibility. A collaborative corporate culture can induce cooperation among employees without asking employees to work in a manner that is counterintuitive, thus gaining the benefits of teams.

Implications of Punctuation Mark Normalization on Text Retrieval

Implications of Punctuation Mark Normalization on Text Retrieval

Date: August 2013
Creator: Kim, Eungi
Description: This research investigated issues related to normalizing punctuation marks from a text retrieval perspective. A punctuated-centric approach was undertaken by exploring changes in meanings, whitespaces, words retrievability, and other issues related to normalizing punctuation marks. To investigate punctuation normalization issues, various frequency counts of punctuation marks and punctuation patterns were conducted using the text drawn from the Gutenberg Project archive and the Usenet Newsgroup archive. A number of useful punctuation mark types that could aid in analyzing punctuation marks were discovered. This study identified two types of punctuation normalization procedures: (1) lexical independent (LI) punctuation normalization and (2) lexical oriented (LO) punctuation normalization. Using these two types of punctuation normalization procedures, this study discovered various effects of punctuation normalization in terms of different search query types. By analyzing the punctuation normalization problem in this manner, a wide range of issues were discovered such as: the need to define different types of searching, to disambiguate the role of punctuation marks, to normalize whitespaces, and indexing of punctuated terms. This study concluded that to achieve the most positive effect in a text retrieval environment, normalizing punctuation marks should be based on an extensive systematic analysis of punctuation marks and punctuation patterns and ...
