A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

Date: August 2002
Creator: Abney, Paul C.
Description: Counselor self-awareness is considered an important aspect of counseling effectiveness according to the American Counseling Association and the American Psychological Association and in numerous studies and articles within the counseling literature. With the effort to improve the effectiveness of counseling practicum students comes the need to understand the relationship between effectiveness ratings and the levels of counselor self-awareness. Gestalt Therapy literature, and the development of the Personal Orientation Inventory (Shostrom, 1963) provided the working definition of self-awareness in this study. Research and evaluation are means for improving the correlation between students' characteristics in counselor training programs and their effectiveness as perceived by faculty and doctoral supervisors. The purpose of this study was to determine the effects of practicum students' ages and their levels of self-awareness upon counseling effectiveness as measured by faculty and doctoral supervisors in a university clinic setting. Twenty-nine students who were enrolled in four practicum classes were administered the Personal Orientation Instrument. Four faculty supervisors and eight doctoral supervisors were administered the Counselor Effectiveness Rating Scale (Myrick & Kelley, 1971). The instruments were administered in the tenth week of the counseling practicum semester. Analyses of the data revealed a statistically significant interaction between the older practicum students' ...

Source Apportionment Analysis of Measured Volatile Organic Compounds in Corpus Christi, Texas

Source Apportionment Analysis of Measured Volatile Organic Compounds in Corpus Christi, Texas

Date: May 2014
Creator: Abood, Ahmed T.
Description: Corpus Christi among of the largest industrialized coastal urban areas in Texas. The strategic location of the city along the Gulf of Mexico allows for many important industries and an international business to be located. The cluster of industries and businesses in the region contribute to the air pollution from emissions that are harmful to the environment and to the people living in and visiting the area. Volatile organic compounds (VOC) constitute an important class of pollutants measured in the area. The automated gas chromatography (Auto GC) data was collected from Texas Commission of Environmental Quality (TCEQ) and source apportionment analysis was conducted on this data to identify key sources of VOC affecting this study region. EPA PMF 3.0 was employed in this sources apportionment study of measured VOC concentration during 2005 - 2012 in Corpus Christi, Texas. The study identified nine optimal factors (Source) that could explain the concentration of VOC at two urbane monitoring sites in the study region. Natural gas was found to be the largest contributor of VOC in the area, followed by gasoline and vehicular exhaust. Diesel was the third highest contributor with emissions from manufacturing and combustion processes. Refineries gases and evaporative fugitive emissions ...

Boosting for Learning From Imbalanced, Multiclass Data Sets

Boosting for Learning From Imbalanced, Multiclass Data Sets

Access: Use of this item is restricted to the UNT Community.
Date: December 2013
Creator: Abouelenien, Mohamed
Description: In many real-world applications, it is common to have uneven number of examples among multiple classes. The data imbalance, however, usually complicates the learning process, especially for the minority classes, and results in deteriorated performance. Boosting methods were proposed to handle the imbalance problem. These methods need elongated training time and require diversity among the classifiers of the ensemble to achieve improved performance. Additionally, extending the boosting method to handle multi-class data sets is not straightforward. Examples of applications that suffer from imbalanced multi-class data can be found in face recognition, where tens of classes exist, and in capsule endoscopy, which suffers massive imbalance between the classes. This dissertation introduces RegBoost, a new boosting framework to address the imbalanced, multi-class problems. This method applies a weighted stratified sampling technique and incorporates a regularization term that accommodates multi-class data sets and automatically determines the error bound of each base classifier. The regularization parameter penalizes the classifier when it misclassifies instances that were correctly classified in the previous iteration. The parameter additionally reduces the bias towards majority classes. Experiments are conducted using 12 diverse data sets with moderate to high imbalance ratios. The results demonstrate superior performance of the proposed method compared ...

Finitness and Verb-Raising in Second Language Acquisition of French by Native Speakers of Moroccan Arabic

Finitness and Verb-Raising in Second Language Acquisition of French by Native Speakers of Moroccan Arabic

Date: August 1996
Creator: Aboutaj, Heidi H. (Heidi Huttar)
Description: In this thesis, the three hypotheses on the nature of early L2 acquisition (the Full Transfer/Full Access view of Schwartz and Sprouse (e.g., 1996), the Minimal Trees view of Vainikka and Young-Scholten (e.g., 1996), and the Valueless Features view of Eubank (e.g., 1996)), are discussed. Analysis of the early French production by two native speakers of Moroccan Arabic is done to determine if the L1 grammar is transferred onto the L2 grammar. In particular, the phenomena of verb-raising (as determined by the verb's position vis-a-vis negation) and finiteness are examined. The results of this study indicate that the relevant structures of Moroccan Arabic do not transfer onto the emerging French grammar.

Development of a Cost Effective Wireless Sensor System for Indoor Air Quality Monitoring Applications

Development of a Cost Effective Wireless Sensor System for Indoor Air Quality Monitoring Applications

Date: May 2014
Creator: Abraham, Sherin
Description: Poor air quality can greatly affect the public health. Research studies indicate that indoor air can be more polluted than the outdoor air. An indoor air quality monitoring system will help to create an awareness of the quality of air inside which will eventually help in improving it. The objective of this research is to develop a low cost wireless sensor system for indoor air quality monitoring. The major cost reduction of the system is achieved by using low priced sensors. Interface circuits had to be designed to make these sensors more accurate. The system is capable of measuring carbon dioxide, carbon monoxide, ozone, temperature, humidity and volatile organic compounds. The prototype sensor node modules were developed. The sensor nodes were the connected together by Zigbee network. The nodes were developed in such a way that it is compact in size and wireless connection of sensor nodes enable to collect air quality data from multiple locations simultaneously. The collected data was stored in a computer. We employed linear least-square approach for the calibration of each sensor to derive a conversion formula for converting the sensor readings to engineering units. The system was tested with different pollutants and data collected was ...
