A Comparison of the Ovulation Method With the CUE Ovulation Predictor in Determining the Fertile Period

The purpose of this study was to compare the CUE Ovulation Predictor with the ovulation method in determining the fertile period. Eleven regularly ovulating women measured their salivary and vaginal electrical resistance (ER) with the CUE, observed their cervical-vaginal mucus, and measured their urine for a luteinizing hormone (LH) surge on a daily basis. Data from 21 menstrual cycles showed no statistical difference (T= 0.33, p= 0.63) between the CUE fertile period, which ranged from 5 to 10 days (mean = 6.7 days, SD = 1.6), and the fertile period of the ovulation method, which ranged from 4 to 9 days (mean = 6.5 days, SD = 2.0). The CUE has potential as an adjunctive device in the learning and use of natural family planning methods

Desigm and Development Considerations of a Learning Object Repository

A learning objects repository (LOR) is a web-based educational portal that houses, displays, and delivers sharable content objects for educational purposes. Design of such a repository encounters a number of considerations that relate the behavior of the information system to the content objects it manages. This paper examines these design issues in light of standards we have utilized. In particular, the instructional design of our learning objects is based on a concept called progressive scaffolding, which refers to the process of providing differing levels of media guidance. A brief description of related research is included. Furthermore, our objects are compliant with the Advanced Distributed Learning’s Sharable Content Object Reference Model (SCORM) to ensure they behave in a uniform and predictable manner. This paper also reviews existing content portals and gives a summary of an evaluation project carried out with a prototype

Designing Motorcycles via the Web: Improved Aesthetics and Consumer Preference

The purpose of this research was to examine how manipulation of the aesthetic appeal of a motorcycle’s image on a web page might elucidate trends in consumer preference. To this end, website visitors were encouraged to reconfigure a blueprint of motorcycle to make it more appealing. These alterations to its confirmation were analyzed to identify patterns of preference that were then compared to the marketplace in general. It was observed that aesthetic preferences recognized by the design method were similar to trends within the motorcycle building/buying public

A Student Response System for Increasing Engagement, Motivation, and Learning in High Enrollment Lectures

Student response systems (SRS) are devices that allow students to provide categorical and numerical responses to questions embedded within a lecture, and the responses can be tallied and scored in various ways to provide immediate feedback to the students and/or professors. In the fall of 2004 at the University of Missouri – Rolla, questions were systematically integrated into large general chemistry lecture sections, and students used the response system to answer. In order to evaluate the system, students’ test scores were compared with previous years, and a survey was administered with the aim of evaluating the system at the end of the course when SRS was used. Test scores indicated substantial improvement from previous years. In addition, survey results indicated that a significant majority of the students found that the SRS made the course more engaging, motivational, and increased learning. Qualitative analyses of students’ open-ended responses provided support and additional insights for the quantitative analyses

Reservoir quality and burial model evaluation by kinetic quartz and illite cementation modeling : Case study of Rotliegendes, north Germany

Silicate reaction kinetics provide a complementary means to other established paleothermal indicators such as organic maturation for evaluating thermal reconstructions. In this study we combine the use of an organic maturation model with kinetic models for quartz and illite cementation to evaluate burial history scenarios for five subsalt wells in lithologically and structurally complex Rotliegendes reservoirs. Models for organic maturation are most sensitive to maximum temperature and provide no direct evidence for the time of peak temperature or the overall duration of high temperatures. By contrast, the kinetics of quartz cementation are much more strongly influenced by the duration of exposure to high temperatures compared with organic indicators. Kinetic models for fibrous illite formation similarly are sensitive to time and temperature and provide predictions for the time of illite formation that can be compared with radiometric dates. Used collectively, these organic and inorganic paleothermal indicators provide improved constraints on thermal evolution compared with conventional approaches. In this study we use these indicators to evaluate two alternative burial history scenarios. Scenario 1 incorporates a hypothesized Jurassic heat flow peak together with significant Late Jurassic deposition and subsequent erosion. Scenario 2 omits the Jurassic heat flow peak and omits the deposition and erosion of the Upper Jurassic. Although both of these scenarios are consistent with organic maturation data, scenario 2 leads to a far better match with quartz cement volumes and fibrous illite K-Ar dates

Integration of a smoking cessation program in the treatment protocol for patients with head and neck and lung cancer

Smoking is the main causative factor for development of head and neck and lung cancer. In addition, other malignancies such as bladder, stomach, colorectal, kidney and pancreatic cancer have a causative relation with smoking. Continued smoking after having been diagnosed with cancer has many negative consequences: effectiveness of radiotherapy is diminished, survival time is shortened and risks of recurrence, second primary malignancies and treatment complications are increased. In view of the significant health consequences of continued smoking, therefore, additional support for patients to stop smoking seems a logical extension of the present treatment protocols for smoking-related cancers. For prospectively examining the effect of nursing-delivered smoking cessation programme for patients with head and neck or lung cancer, 145 patients with head and neck or lung cancer enrolled into this programme over a 2-year period. Information on smoking behaviour, using a structured, programme specific questionnaire, was collected at baseline, and after 6 and 12 months. At 6 months, 58 patients (40%) had stopped smoking and at 12 months, 48 patients (33%) still had refrained from smoking. There were no differences in smoking cessation results between patients with head and neck and lung cancer. The only significant factor predicting success was whether the patient had made earlier attempts to quit smoking. A nurse-managed smoking cessation programme for patients with head and neck or lung cancer shows favourable long-term success rates. It seems logical, therefore, to integrate such a programme in treatment protocols for smoking-related cancers
