An investigation of the effective supervision and communication competence of chief student affairs officers in Christian institutions of higher education.

An investigation of the effective supervision and communication competence of chief student affairs officers in Christian institutions of higher education.

Date: December 2007
Creator: Wilcoxson, Douglas A.
Description: The purpose of this study was to examine if there is an association between effective supervision and communication competence in divisions of student affairs at Christian higher education institutions. The investigation examined chief student affairs officers (CSAOs) and their direct reports at 45 institutions across the United States using the Synergistic Supervision Scale and the Communication Competence Questionnaire. A positive significant association was found between the direct report's evaluation of the CSAO's level of synergistic supervision and the direct report's evaluation of the CSAO's level of communication competence. The findings of this study will advance the supervision and communication competence literature while informing practice for student affairs professionals. This study provides a foundation of research in the context specific field of student affairs where there has been a dearth of literature regarding effective supervision. This study can be used as a platform for future research to further the understanding of characteristics that define effective supervision.

An investigation of the effects of SFAS No.121 on asset impairment reporting and stock returns

An investigation of the effects of SFAS No.121 on asset impairment reporting and stock returns

Date: December 2001
Creator: Alshabani, Waleed Mohammad
Description: Prior to Statement of Financial Accounting Standards No.121 (SFAS No.121): Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of, managers had substantial discretion concerning the amount and timing of reporting writedowns of long-lived assets. Moreover, the frequency and dollar amount of asset writedown announcements that led to a large “surprise” caused the Financial Accounting Standards Board (FASB) and the Securities and Exchange Commission (SEC) to consider the need for a new standard to guide the recording of impairment of long-lived assets. This study has two primary objectives. First, it investigates the effects of SFAS No.121 on asset impairment reporting, examining whether SFAS No.121 reduces the magnitude and restricts the timing of reporting asset writedowns. Second, the study compares the information content (surprise element) of the asset impairment loss announcement as measured by cumulative abnormal returns (CAR) before and after the issuance of SFAS No.121. The findings provide support for the hypothesis that the FASB's new accounting standard does not affect the magnitude of asset writedown losses. The findings also provide support for the hypothesis that SFAS No. 121 does not affect the management choice of the timing for reporting asset writedowns. In addition, the findings ...

An Investigation of the Efficacy of Play Therapy with Young Children

An Investigation of the Efficacy of Play Therapy with Young Children

Date: May 1999
Creator: Brandt, Marielle Aloyse
Description: This study was designed to determine the effectiveness of play therapy as a method of intervention for children with a variety of emotional and behavioral problems. Specifically, the study was aimed at determining the effectiveness of play therapy in: (a) improving self-concepts of children with adjustment difficulties; (b) reducing internalizing behavior problems, such as withdrawal, somatic complaints, anxiety, and depression; (c) reducing externalizing behavioral problems such as aggression and delinquent behaviors; (d) reducing overall behavior problems, social problems, thought problems, and attention problems of children with adjustment difficulties; and (e) reducing parenting stress of parents of children who were experiencing adjustment difficulties.The experimental group consisted of 15 children who were experiencing a variety of adjustment difficulties and received play therapy once per week for 7 to 10 weeks. The control group consisted of 14 children who were experiencing a variety of adjustment difficulties and who were on a waiting list to receive intervention, and therefore, did not receive any treatment during the time of data collection. Experimental and control group children were administered the Joseph Pre-School and Primary Self-Concept Screening Test and parents of all participants completed the Child Behavior Checklist and the Parenting Stress Index at pretest and posttest ...

Investigation of the feasibility of non-invasive carbon dioxide detection using spectroscopy in the visible spectrum.

Investigation of the feasibility of non-invasive carbon dioxide detection using spectroscopy in the visible spectrum.

Date: December 2007
Creator: Marks, Damian
Description: Pulse oximeters are used in operating rooms and recovery rooms as a monitoring device for oxygen in the respiratory system of the patient. The advantage of pulse oximeters over other methods of oxygen monitoring is that they are easy to use and they are non-invasive, which means it is not necessary break the skin to extract blood for information to be obtained. The standard for the measurement of partial pressure of CO2 and O2 is an arterial blood gas analysis (ABG). However routine monitoring using this method on a continuous basis is impractical since it is slow, painful and invasive. Measuring carbon dioxide is critical to preventing ailments such as carbon dioxide poisoning or hypoxia. The problem is, currently there is no known effective non-invasive method for accurately measuring carbon dioxide in the body to properly assess the adequacy of ventilation. The objective of this study was to experimentally use spectroscopy in the visible spectrum and the principles of operation of a pulse oximeter to incorporate a method of non-invasive real-time carbon dioxide monitoring that is as quick and easy to use.

An Investigation of the Impact of Technology Expenditures on Student Achievement in Texas Districts

An Investigation of the Impact of Technology Expenditures on Student Achievement in Texas Districts

Date: August 2005
Creator: Hancock, Robert
Description: The purpose of this study was to explore the relationship between money spent on technology hardware, software, and training on district-wide achievement as measured by Texas standardized achievement tests, the Scholastic Aptitude Test (SAT), and the American College Test (ACT). A series of studies were carried out to develop a model of the relationship between Texas district TAKS, TAAS, ACT, and SAT scores for all subjects and district expenditures on technology hardware, technology software, and technology training. The findings of this study showed that although the mixture of uneven distribution of training, incentives, and equipment in these Texas districts clouds the issue of effective integration as it does for all districts (Anderson & Becker, 1998), and the mean level of per pupil technology expenditure for participating districts is of an amount ($192 per student) deemed unlikely to have substantial impact on student outcomes (Anderson & Becker, 1998), there are strong positive links between levels of expenditure and student achievement on the Texas Assessment of Knowledge and Skills and the American College Test that indicate that establishing guidelines for levels of expenditure, schedules of acquisition of materials and equipment, and timeframes for training and implementation may be vital to the success ...
