An Experimental Investigation of the Relationship Between Perception of Parental Acceptance and Social Acceptability of Adolescents

An Experimental Investigation of the Relationship Between Perception of Parental Acceptance and Social Acceptability of Adolescents

Date: 1955
Creator: Throp, Thomas Richard
Description: The purpose of this study is twofold. One is that of developing an instrument for determining a child's concept of how he is thought of by his mother and his father; in other words, a method of measuring parental acceptance as it is perceived by the child, himself. The development of this instrument will be discussed in Chapter IV. The second purpose of this study is that of determining whether or not there is any significant relationship between the child's perception of parental acceptance and the social acceptability of the child, as measured by a sociometric instrument.

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning

Date: August 2000
Creator: Alzafiri, Fayiz M.
Description: The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learners’ performances while soldering. The 2 x 2 factorial model with interaction ...

An Experimental Study of Bifurcated (Weekend and Weekday) and Unitary (Past Week) Retrospective Assessments of Sleep

An Experimental Study of Bifurcated (Weekend and Weekday) and Unitary (Past Week) Retrospective Assessments of Sleep

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Sethi, Kevin J.
Description: Discordance between weekday and weekend sleep schedules is common (Bonnet & Arand, 1995; Breslau, Roth, Rosenthal, & Andreski, 1997; Machado, Varella, & Andrade, 1998; Strauch & Meier, 1988; Tsai & Li, 2004). Brief retrospective self-report measures are essential for epidemiological research studies (Moul, Hall, Pilkonis, & Buysse, 2004), but self-reports are prone to error in recall, and the greater the variability in nightly sleep, the less reliable are retrospective reports (Babkoff, Weller, & Lavidor, 1996). More accurate self-report responses may be possible if measures prompt participants to consider variations in sleep schedules that are consistent (i.e., weekday and weekend sleep schedules). The current study experimentally examined whether Bifurcated (Weekday and Weekend) retrospective assessments of sleep are more accurate than Unitary (Past Week) assessments. Participants were randomly assigned to complete one of the two versions (Bifurcated vs. Unitary) of the Sleep Questionnaire. One hundred and thirty-one participants were included in the analyses. Results of a a series of analyses demonstrated that the Bifurcated version of the Sleep Questionnaire provided more accurate and less variable estimates of total sleep time than the Unitary version of the Sleep Questionnaire. Differences between the versions of the Sleep Questionnaire for other sleep variables were less ...

An Experimental Study of Collision Broadening of some Excited Rotational States of the Bending Vibration of Methyl Cyanide

An Experimental Study of Collision Broadening of some Excited Rotational States of the Bending Vibration of Methyl Cyanide

Date: May 1993
Creator: Hajsaleh, Jamal Y. (Jamal Yousef)
Description: A double modulation microwave spectrometer is used to evaluate the linewidth parameters for some excited rotational components in the bending vibration v_8 of 13CH3 13C 15N and 13CH3C15N isotopomers of methyl cyanide. The linewidth parameters for self-broadening of the ΔJ=2←1 rotational components for the ground v_8 , 1v_8, and the 2v_8 vibrations were determined over a pressure range of 1 to 13 mtorr and at a temperature of 300 K. The double modulation technique is used to explore the high eighth derivative of the line shape profile of the spectral line. This technique proved to give good signal-to-noise ratios and enabled the recovery of weak signals. An experimental method is developed to correct for source modulation broadening. The tests of the ratios of the two inner peak's separation of the eighth derivative of the line showed that they were up to 95% similar to those for a Lorentzian line shape function. The line shapes were assumed to be Lorentzian for the theoretical analysis of the derivative profiles and comparisons were made between experiment and theory on this basis. Dipole moments for vibrationally excited states were calculated from linewidth parameters and show systematic decrease with the increase of excitation. Impact parameters ...

An Experimental Study of Teachers' Verbal and Nonverbal Immediacy, Student Motivation, and Cognitive Learning in Video Instruction

An Experimental Study of Teachers' Verbal and Nonverbal Immediacy, Student Motivation, and Cognitive Learning in Video Instruction

Date: May 2000
Creator: Witt, Paul L.
Description: This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to enhance learning; and second, how immediacy affects cognitive learning in relation to student motivation. These questions were examined in the context of video instruction to provide insight into distance learning processes and to ensure maximum control over experimental manipulations. Participants (N = 347) were drawn from university students in an undergraduate communication course. Students were randomly assigned to groups, completed a measure of state motivation, and viewed a 15-minute video lecture containing part of the usual course content delivered by a guest instructor. Participants were unaware that the video instructor was actually performing one of four scripted manipulations reflecting higher and lower combinations of specific verbal and nonverbal cues, representing the four cells of the 2x2 research design. Immediately after the lecture, students completed a recall measure, consisting of portions of the video text with blanks in the place of key words. Participants were to fill in the blanks with exact words they recalled from the videotape. ...

Experimental Study on Fluidization of Biomass, Inert Particles, and Biomass/Sand Mixtures

Experimental Study on Fluidization of Biomass, Inert Particles, and Biomass/Sand Mixtures

Date: May 2011
Creator: Paudel, Basu
Description: Fluidization of biomass particles is an important process in the gasification, pyrolysis and combustion in order to extract energy from biomass. Studies on the fluidization of biomass particles (corn cob and walnut shell), inert particles (sand, glass bead, and alumina), which are added to facilitate fluidization of biomass, and biomass/sand mixture were performed. Experiments were carried out in a 14.5 cm internal diameter cold flow fluidization bed to determine minimum fluidization velocities with air as fluidizing medium. On the of basis of experimental data from both present work and those found in the literature, new correlations were developed to predict minimum fluidization velocity for inert particles as well as biomass particles. It was found that the proposed correlations satisfactorily predict minimum fluidization velocities and was in well agreement with experimental data. Furthermore, effect of weight percentage of biomass in the biomass/sand mixtures was studied. The weight fraction of biomass particles in the mixture was chosen in the range of 0 ~ 100 wt. %. The results show that minimum fluidization velocity of the mixtures increases with an increase in biomass content. Using the present experimental data, a new correlation was developed in terms of mass ratio for predicting values of ...

An Experimental Study on Situated and Dynamic Learning Assessment (SDLA) Environment

An Experimental Study on Situated and Dynamic Learning Assessment (SDLA) Environment

Date: May 2010
Creator: Lee, Zeng-Han
Description: The current supplementary web based English learning in Taiwan provides online learning resources and gives assessments at the end of each lesson to evaluate learners' online learning results. Based on the testing results, instructors may adjust their in-class instructional method to focus on the students' weaknesses. For the average classroom size of 40 students with one instructor, it is extremely difficult to provide individual learning content for each learner's needs because each student has his or her own weaknesses. This study conducted the situated environment with Vygotsky's dynamic assessment theory to test learner's learning achievements and satisfactions as compared to the current web learning environment. The study finds that when both groups of Taiwanese students used Internet based learning, those that utilized the situated and dynamic learning assessment environment showed a statistically significant higher achievement score than those using only the current online learning environment (p < .01). In addition, learners in the SDLA environment had statistically significant higher satisfaction scores than those in the current web learning environment.

Experimental Synchronization of Chaotic Attractors Using Control

Experimental Synchronization of Chaotic Attractors Using Control

Date: December 1994
Creator: Newell, Timothy C. (Timothy Charles)
Description: The focus of this thesis is to theoretically and experimentally investigate two new schemes of synchronizing chaotic attractors using chaotically operating diode resonators. The first method, called synchronization using control, is shown for the first time to experimentally synchronize dynamical systems. This method is an economical scheme which can be viably applied to low dimensional dynamical systems. The other, unidirectional coupling, is a straightforward means of synchronization which can be implemented in fast dynamical systems where timing is critical. Techniques developed in this work are of fundamental importance for future problems regarding high dimensional chaotic dynamical systems or arrays of mutually linked chaotically operating elements.
