Determination of the Lactate Threshold by Respiratory Gas Exchange Measures and Blood Lactate Levels During Incremental-Load Work

Determination of the Lactate Threshold by Respiratory Gas Exchange Measures and Blood Lactate Levels During Incremental-Load Work

Date: December 1987
Creator: Duvillard, Sergei Petelin von.
Description: The purpose of this investigation was to examine the change in pulmonary ventilation (V_E), ventilatory equivalent of oxygen (VE_O_2) and lactic acid (LA) in relation to oxygen uptake (V_O_2) as predictors of the lactate threshold (LT). Eight healthy male (21.9 ± 3.0 years) subjects conducted three incremental-load tests. In each test the initial work rate consisted of 4 minutes of unloaded pedaling ("0" load) followed by incremental-load work of 360 Kgm • min^-1 at 60 rpm for trial I and trial II, while during trial III the work rate consisted of 540 Kgm • min^-1 of incremental-load work at 90 rpm. Work load was increased every third minute until the subject reached voluntary exhaustion. Blood samples from a forearm vein were collected during trial II (60 rpm) and trial III (90 rpm) and analyzed for lactic acid. In our subjects the measured (x̄ ± SD) lowest VE_O_2 for O_2 in relation to V_O_2 for trial I of 22.9 ± 1.9 occurred at a V_O_2 of 1.27 ± 0.8 L • min^-1. For trial II the VE_O_2 of 22.4 ± 1.3 occurred at a V_O_2 of 1.30 ± 0.09 L • min^-1, while for trial III a VE_O_2 of 24.4 ± ...

Development of a Discouragement Scale for Adults with Normative Data for Gay Males

Development of a Discouragement Scale for Adults with Normative Data for Gay Males

Date: December 1996
Creator: Chernin, Jeffrey N.
Description: According to Alfred Adler, founder of Individual Psychology, a feeling of inferiority is in some degree common to all people. People who are unable to overcome these inferiority feelings by striving for cooperation may become discouraged. Although there are three scales to measure social interest, no scales measuring discouragement for adults was found. Additionally, Adler held basic assumptions regarding homosexuality, and the findings suggest that the assumptions should be reexamined. The purpose of this study was twofold. First, three University of North Texas candidates developed a discouragement scale for adults 18 years of age and older, known as the Discouragement Scale for Adults (DSA). Discouragement was examined relative to the five life tasks. Second, this candidate normed the instrument for the scores of gay male subjects and compared it to the scores of the other subject groups. Since the emphasis was on developing the instrument and norming it for various subject groups, no hypothesis was developed. Data was collected on three subject groups, known as the general norm subjects, the discouraged subjects, and the gay male subjects. Analyses were performed on the scores. Among the analyses, it was found that gay male subjects were slightly more discouraged than the general ...

Development of a System for Reporting Disciplinary Problems by Utilizing Data Processing

Date: August 1973
Creator: Cowand, Keith Parker
Description: The problem of this study was to develop and prepare a data processing system that would report, catalog, and file information pertaining to discipline of students referred to the principal. The purposes of the study were to develop a systematic approach to the reporting of disciplinary incidents, to develop a system of reports that could show what actions were being taken in specified areas and that could provide a cross reference of this information with other data, and to provide a system whereby information concerning disciplinary problems and actions taken could be compiled for a future longitudinal study.

Educators' Technology Level of Use and Methods for Learning Technology Integrations.

Educators' Technology Level of Use and Methods for Learning Technology Integrations.

Date: August 2003
Creator: Griffin, Darlene Ann
Description: The purpose of this study was to describe technology learning methods that teachers attend and perceive as effective. The goal was to provide district personnel data that may be utilized when planning for more effective technology staff development. This study examined (1) the methods of learning instructional technology that are being utilized by teachers and administrators and (2) why these methods are being utilized in two Texas school districts. Data was collected from educators via an online survey consisting of demographics, technology training methods, level of technology use (CBAM 1 item), stages of adoption and technology level of use (LoTi, 50-item). Educators with different technology levels of use (high, low) differed on their perceptions and utilization of technology training methods. Specifically, educators with different technology levels of use differed in their perceptions of independent online help, and learning through trial and error technology training methods. Results from the study showed that educators tended to use the technology training method that they perceived as most effective. Educators tended to utilize learning by trial and error, peer support, and technology personnel support the most frequently for learning technology integration Educators' in the study had varying technology levels of use based on their ...
