Task Lighting

Classrooms are radically changing across United States campuses. Rooms that were once dominated by bright lights, chalkboards, and overhead projectors, are being transformed into multimedia “master classrooms,” complete with task lighting, video projectors, visualizers, laserdisc and videotape players, soft boards, and computers. What are these pieces of equipment, how much do they cost, and how can they be implemented into a horticultural curriculum? Computer hardware and software empowers today's educator with a multimedia development studio on his or her desktop to create simple slide presentations or complex, interactive multimedia applications. However, it is not multimedia itself, any more than it was the chalkboard, that makes a powerful, educational presentation, rather it is the educator's creativity, use of instructional methods, and delivery.

The Third International Mathematics and Science Study (TIMSS) reported more than just numerical achievement data. The study also contained information on teachers' lives, students' lives, and curricula, as well as a videotape of eighth-grade mathematics classes (OERI 1996a). These data, especially the videotaped study, go beyond comparisons of achievement scores and allow for cross-cultural comparisons of mathematics instruction in the United States and other countries. In particular, we can learn many lessons from examining instructional methods in the United States and comparing them with those of Japan. This comparison has significant implications for implementing NCTM's Standards in U.S. classrooms and teaching our students as if they were young mathematicians.

sIn September 1960, Fidel Castro announced to the world that Cuba would, within a year's time, teach more than one million illiterate adult Cubans to read and write. In this article, based on interviews conducted by the author in Cuba and on publications not generally available in the United States, Jonathan Kozol traces the history and documents the success of the Cuban literacy campaign. Outlining the immense logistical and pedagogical challenges of this effort, he describes the recruitment and training of the volunteer teachers and the development of instructional methods that were frankly political in nature and intent. Kozol concludes the article with personal accounts by two young members of the campaign forces that provide a case study of the application of Paulo Friere's educational principles.

Natural Means

Water tables in aquifer regions of the southwest United States are dropping off at a rate which is greater than can be replaced by natural means. It is estimated that by 1985 wells will run dry in this region unless adequate artificial recharging can be accomplished. Recharging with surface water is limited by the plugging of permeable rock formations underground by clay particles and organic debris.A controlled study was initiated in which sand grains were used as the rock formation and water with known clay concentrations as the recharge media. The plugging mechanism was investigated by direct observation in the SEM of frozen hydrated sand samples from selected depths.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.

An outbreak of unexplained acute pulmonary syndrome with high fatality was recognized in the spring of 1993 in the southwestern United States. The cause of the illness was quickly identified serologically and genetically as a hantavirus and the disease was named hantavirus pulmonary syndrome (HPS). Recently, the virus was isolated from deer mice which had been trapped near the homes of HPS patients, and cultivated in Vero E6 cells. We identified the cultivated virus by negative-stain direct and colloidal gold immune electron microscopy (EM).Virus was extracted, clarified, and concentrated from unfixed and 0.25% glutaraldehyde fixed supernatant fluids of infected Vero E6 cells by a procedure described previously. Concentrated virus suspensions tested by direct EM were applied to glow-discharge treated formvar-carbon filmed grids, blotted, and stained with 0.5% uranyl acetate (UA) or with 2% phosphotungstic acid (PTA) pH 6.5. Virus suspensions for immune colloidal gold identification were adsorbed similarly to filmed grids but incubated for 1 hr on drops of 1:50 diluted monoclonal antibody to Prospect Hill virus nucleoprotein or with 1:50 diluted sera from HPS virus infected deer mice.

In recent years it became apparent that we needed to improve productivity and efficiency in the Microscopy Laboratories in GE Plastics. It was realized that digital image acquisition, archiving, processing, analysis, and transmission over a network would be the best way to achieve this goal. Also, the capabilities of quantitative image analysis, image transmission etc. available with this approach would help us to increase our efficiency. Although the advantages of digital image acquisition, processing, archiving, etc. have been described and are being practiced in many SEM, laboratories, they have not been generally applied in microscopy laboratories (TEM, Optical, SEM and others) and impact on increased productivity has not been yet exploited as well.In order to attain our objective we have acquired a SEMICAPS imaging workstation for each of the GE Plastic sites in the United States. We have integrated the workstation with the microscopes and their peripherals as shown in Figure 1.
