The Influence of the Instructor's Written Comments upon Student Test Performance in the College Classroom

The Influence of the Instructor's Written Comments upon Student Test Performance in the College Classroom

Date: December 1970
Creator: Mapel, Seldon Barclay
Description: The problem with which this investigation is concerned is that of determining the influence of instructors' written comments on the test performances of students in selected college subjects. The students were from one university and one junior college. The written comments were designed to be positive in nature and to encourage better future test performances by students. The comments were made in regard to the letter grades received by the students and were placed only on major (as defined by each instructor) objective tests.

Information System Quality: An Examination of Service-Based Models and Alternatives

Date: August 1997
Creator: Maples, Glenn (Glenn Edward)
Description: Service quality as a component of overall Information Systems quality is examined. Three related studies test the SERVQUAL and related instruments (SERVPERF and Importance-weighted SERVPERF) using Information System users. SERVPERF outperformed SERVQUAL in all three studies.

Characterization of boron nitride thin films on silicon (100) wafer.

Characterization of boron nitride thin films on silicon (100) wafer.

Date: August 2007
Creator: Maranon, Walter
Description: Cubic boron nitride (cBN) thin films offer attractive mechanical and electrical properties. The synthesis of cBN films have been deposited using both physical and chemical vapor deposition methods, which generate internal residual, stresses that result in delamination of the film from substrates. Boron nitride films were deposited using electron beam evaporation without bias voltage and nitrogen bombardment (to reduce stresses) were characterize using FTIR, XRD, SEM, EDS, TEM, and AFM techniques. In addition, a pin-on-disk tribological test was used to measure coefficient of friction. Results indicated that samples deposited at 400°C contained higher cubic phase of BN compared to those films deposited at room temperature. A BN film containing cubic phase deposited at 400°C for 2 hours showed 0.1 friction coefficient.

Similarities and Differences in Borderline and Other Symptomology Among Women Survivors of Interpersonal Trauma with and Without Complex Ptsd

Similarities and Differences in Borderline and Other Symptomology Among Women Survivors of Interpersonal Trauma with and Without Complex Ptsd

Date: December 2012
Creator: Marchesani, Estee Simpkins
Description: Women interpersonal chronic trauma survivors are frequently misdiagnosed with borderline personality disorder (BPD) or post traumatic stress disorder (PTSD), which often results in mistreatment. Neither PTSD nor BPD adequately describes the unique character alterations observed among those exposed to prolonged early childhood trauma. Researchers suggest survivors of interpersonal and chronic trauma should be subsumed under complex PTSD (CPTSD)(MacLean & Gallop, 2003). The primary purpose of this study was to test the validity of complex PTSD as a construct. MANOVA, ANOVA, chi- Square, and independent samples t- Tests were utilized to test hypotheses. Results revealed that women who experienced higher frequencies of trauma met more CPTSD criteria and had higher mean base rate scores on the Major Depression, Depressive, Avoidant, Masochistic, Anxiety, PTSD, and Borderline scales of the MCMI- III than women who experienced fewer traumas. Additionally, findings suggest that the Major Depression, Depressive, Anxiety, PTSD, and Borderline scales may highlight differences among women interpersonal trauma survivors who meet five of six CPTSD criteria versus those who meet full CPTSD diagnostic criteria. Lastly, the mean Borderline scale score for women who met full CPTSD diagnostic criteria was below the cutoff for personality traits. Overall, these findings provide evidence and validation for ...

Selective Lipid Absorption

Selective Lipid Absorption

Date: January 1960
Creator: Marcia, John Albion
Description: An experiment was designed to study in the same animal any preferential absorption of a free fatty acid in the presence of a triglyceride of the same fatty acid. Rats were administered a mixture of free fatty acid and its triglyceride labeled with carbon-13 and carbon-14 respectively. Each isotope in the fed lipid and in the lipid recovered from the gastrointestinal tract was measured. The isotope effect, if any, was studied by administering a mixture of palmitic acid-1-C13 and palmitic acid-1-C14.

Examination of Sleep Disparities Among a Racially/ethnically Diverse Sample of Adolescents

Examination of Sleep Disparities Among a Racially/ethnically Diverse Sample of Adolescents

Date: May 2012
Creator: Marczyk, Katherine D.
Description: Racial, ethnic and gender disparities have been found among a variety of health variables, but to date no study has comprehensively examined whether similar differences exist between sleep variables such as duration, efficiency and quality, in early adolescence. There is a general consensus among previous literature that adolescence is a time when a decrease in total sleep time and an increase in sleep problems are observed. Previous literature, however, mainly focused on the influence of puberty to explain these changes. the current study examined if differences exist between 1462 Caucasian, Hispanic/Latino, and African American early adolescents (ages 10-14 years) on sleep duration, efficiency and quality. Results showed that adolescent boys reported significantly longer sleep durations, better sleep quality, shorter sleep onset latencies, and later rise times than girls. Results also showed that sixth graders slept longer than seventh and eighth graders, and that seventh graders woke up much earlier than the other two grades. Lastly, results showed that Caucasian students reported longer sleep onset latencies and lower sleep efficiencies than African American students. Trends were observed for boys having greater sleep efficiencies than girls and for Caucasian students sleeping longer than Hispanic students. Based on the differences observed in our ...

Teaching Simple Auditory Discriminations to Students with Autism

Teaching Simple Auditory Discriminations to Students with Autism

Date: December 2008
Creator: Marino, Kristine L.
Description: This study aimed to test the effectiveness of classroom translations of some laboratory procedures for teaching simple auditory discriminations to learners with developmental disabilities. Three participants with autism and mental retardation were trained to make topographically distinct responses in the presence of two different stimuli, either a pure tone and silence, or two tones. A portable electronic piano keyboard was used to produce tones. Delayed prompt and differential reinforcement procedures were used to teach the responses. None of the participants performed the discriminations accurately without prompting despite numerous revisions to the procedures.
