1. A Case Study: Experiences in Developing Online Courses at a Community College.

Author

Henning, Neal L.

Abstract

This study examined the experiences of nine faculty members in the development of two online courses at a community college in southeast Nebraska. The faculty members used Lotus Notes (software that was adapted for instructional delivery known as computer-mediated communication) as the delivery tool. Data was collected through interviews, observations, and participant-observations. Additionally, all online communications were analyzed. Findings included: (1) a single faculty member should not develop a course on his/her own-diverse groups help to ensure that the entire scope of the course is attended to; (2) faculty members need time to experiment and have fun so that they can become comfortable with the software and hardware; (3) faculty participants should be given the opportunity to be students before becoming online instructors; (4) it is important to screen faculty members before starting the actual training process for online course development-prospective participants should be screened for technical aptitude; and (5) online learning needs assessment in several areas. The development process of moving from a traditional classroom to an online environment is a time-consuming and complex task. This report records these experiences. (Contains 125 references.) (EMH)

3. Breaking through 'The Dominion of Facts': Sarah Josepha Hale's Instructive Legacy.

Author

Henning, Martha L.

Abstract

The 18th and 19th centuries saw a real tension between inductive and deductive methods of reason. Spokesperson for her era through her association with the popular "Godey's Ladies' Book," Sarah Josepha Hale addressed this tension in 1858, citing an article by Thomas Henry Buckle ascribing the method of deduction to women and that of induction to men, and clearly favoring deduction. Deductive reasoning is centered in community assent, while inductive thought derives from the power of the individual and reinforces that power. Authors of literature of the 1850s (recognized as "the feminine fifties"), such as Harriet Beecher Stowe in "Uncle Tom's Cabin," use symbolic references from which readers deductively construct meaning. Later 1850s' literature reflects and promotes the evaluation of women, with story movement becoming a linear progression. Educational institutions still privilege the inductive, but despite the historical precedent and the current predilection toward inductive reasoning, this can be balanced with some basic and practical implications for the composite pedagogy. In the classroom, where students' cognitive methods differ, various methods of collaborative evaluation can be considered. Taking a cue from Hale, perhaps accepting and teaching a change of mind can make an impact on the culture's order: economic, social, and political. (CR)

15. The Effects of Hearing Aid Compression Parameters on the Short-Term Dynamic Range of Continuous Speech

Author

Henning, Rebecca L. Warner and Bentler, Ruth A.

Abstract

Purpose: The purpose of this study was to evaluate and quantitatively model the independent and interactive effects of compression ratio, number of compression channels, and release time on the dynamic range of continuous speech. Method: A CD of the Rainbow Passage (J. E. Bernthal & N. W. Bankson, 1993) was used. The hearing aid was a programmable, digital, wide dynamic range compression instrument. A fully crossed design and multiple regression analyses were used to evaluate and model the effects of release time (32, 128, and 1024 ms), compression ratio (1:1, 2:1, and 4:1), and number of compression channels (1, 2, and 4 channels) on the short-term octave-band dynamic range of speech. "Dynamic range of speech" was defined as the range between the 1% and 70% exceedance levels within each octave band. Results: As the compression ratio and number of channels increased, and as the release time decreased, the dynamic range of speech decreased. The effects of channels and release time increased as the compression ratio increased. In all conditions, the amount of effective compression for speech was less than the nominal compression ratio. Conclusion: A multiple regression model is provided that predicts the effects of various combinations of compression parameters on the dynamic range of speech.

Abstract

Current tank tests have been performed on two equal-diameter, flexible cylinders in tandem with various end spacings or separation distances. While the cylinders experienced transverse vortex-induced vibration in only the first mode, the test Reynolds numbers were well into the transition range, and the drag crisis was clearly observed on the upstream cylinder. Both acceleration and drag were measured to provide some interesting correlations between vibration, drag, and end spacing for each of the two cylinders. Keywords: vortex-induced vibration (VIV), risers, interference

35. Generating Peptide Mass Spectrometry Ground Truth Data

Author

Henning, Jessica L, Smith, Rob, Henning, Jessica L, and Smith, Rob

Abstract

Very few quantitative evaluations exist for precursor mass spectrometry data due to the lack of tools for enabling the manual feature finding necessary to generate this data. Other lacks the ability to capture, edit, save, and view precursor mass spectrometry data. We present JS-MS 2.0, a software suite that provides a dependency-free, browser-based, one click, cross-platform solution for creating precursor ground truth. The software retains the first version’s capacity for loading, viewing, and navigating MS1 data in 2- and 3-D, and adds tools for capturing, editing, saving and viewing isotopic envelope and extracted isotopic chromatogram features. The software can also be used to view and explore the results of feature finding algorithms. JS-MS 2.0 enables faster creation and inspection of precursor mass spectrometry ground truth data. It is publicly available with a GPL 2.0 license at github.com/optimusmoose/jsms.

Abstract

Analysis of the role of mitochondrial oxidation and glycolysis of lactate, glucose and palmitate during ATP synthesis in working hypertrophied rat hearts reveals that pressure overload-hypertrophied heart exhibits higher glucolysis rates and lower fatty acid oxidation rates than normal heart at low workloads. Glycolysis plays a bigger role in ATP synthesis in hypertrophied hearts than in control hearts. The function of palmitate oxidation in overall ATP synthesis reduces in control and hypertrophied hearts.

Abstract

Safe anaerobic metabolism Naked mole-rats live in large colonies deep underground in hypoxic conditions. Park et al. found that these animals fuel anaerobic glycolysis with fructose by a rewired pathway that avoids tissue damage (see the Perspective by Storz and McClelland). These results provide insight into the adaptations that this strange social rodent has to make for life underground. They also have implications for medical practice, particularly for understanding how to protect tissues from hypoxia. Science , this issue p. 307 ; see also p. 248

Abstract

A wind-tunnel test of a 1/10th-scale Atlas-Centaur I large payload fairing launch vehicle model was conducted in the NASA Langley Transonic Dynamics Tunnel. The wind tunnel model was an aeroelastically-scaled version of the flight vehicle and was capable of simulating either of the first two bending vibration modes of the full-scale vehicle by a partial mode technique. The primary purpose of the test was to gather data concerning buffet response which could be used to clear the vehicle for flight. Additionally, angle-of-attack studies were conducted and several payload fairing configurations were tested to assess the buffet response and dynamic stability of off-design flight conditions and geometric parameters. No dynamic instabilities were found for any of the configurations tested. The buffet response data for the nominal flight configuration indicate that the unsteady buffet loads represent 5 to 10 percent of the total design load; therefore, the buffet loads are not a large factor affecting the overall vehicle design. Payload fairing length-to-diameter ratio variations were found to have small effects on the buffet response of the model, except in the case of the smallest length-to-diameter models for the second bending mode simulation. The effects of angle of attack on buffet response were found to be small. The model was more sensitive to Mach number changes than to angle of attack. The buffet response results from this wind tunnel test were influenced by the tunnel facility vibration levels. An attempt was made to experimentally reduce the effect of the facility mechanical vibration for the nominal flight configuration by testing with vertical rods used to stiffen the sting support. The first flight of the Atlas-Centaur I vehicle successfully occurred on July 25, 1990, and a comparison of flight measurements with wind tunnel data is presented. The flight data was found to be well within the 3 sigma level of the wind tunnel data.

Abstract

The histone chaperone HJURP is a chromatin assembly factor that recruits CENP-A nucleosomes to centromeric chromatin., Centromeres of higher eukaryotes are epigenetically marked by the centromere-specific CENP-A nucleosome. New CENP-A recruitment requires the CENP-A histone chaperone HJURP. In this paper, we show that a LacI (Lac repressor) fusion of HJURP drove the stable recruitment of CENP-A to a LacO (Lac operon) array at a noncentromeric locus. Ectopically targeted CENP-A chromatin at the LacO array was sufficient to direct the assembly of a functional centromere as indicated by the recruitment of the constitutive centromere-associated network proteins, the microtubule-binding protein NDC80, and the formation of stable kinetochore–microtubule attachments. An amino-terminal fragment of HJURP was able to assemble CENP-A nucleosomes in vitro, demonstrating that HJURP is a chromatin assembly factor. Furthermore, HJURP recruitment to endogenous centromeres required the Mis18 complex. Together, these data suggest that the role of the Mis18 complex in CENP-A deposition is to recruit HJURP and that the CENP-A nucleosome assembly activity of HJURP is responsible for centromeric chromatin assembly to maintain the epigenetic mark.
