The United States “Apprenticeship” commemorative pictures the micrometer caliper used in machine shop measurements. The Japanese stamp suggests that length, capacity, and mass are readily measurable. Metric units, the SI abbreviations, and conversion to metric are indicated on the stamps of Korea, Romania, and Tanzania-Kenya-Uganda.

Postage Stamps

Stamp collecting and industrial capitalism in the United States emerged simultaneously in the mid-nineteenth century. England issued the first government postage stamp in 1840, and other nations quickly adopted the idea. The United States printed its first official stamp in 1847, although it was preceded by the provisionals issued by local postmasters. Postage stamps were a product of the industrial revolution. The adoption of the prepaid penny post in England, while opposed by the General Post Office, was widely supported by large merchants who understood that a low-cost, single-rate system was vital to the communication demanded by an increasingly national market. The adhesive label was originally conceived by the English postal reformer, Rowland Hill, as a convenience for illiterates who would not be able to write addresses on the official envelopes that he preferred as proof of prepayment. Within a decade, almost every major nation in the world had borrowed this device, which became a symbol of the economic transformation of the nineteenth century. I would argue that the collecting of these tokens was a microcosmic performance of the system that created them. Stamp collectors took on many of the key roles of actors in the market economy and played out various conflicts embodied in the larger society in the philatelic arena.

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.

Quantitative Image

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.

Communities Of Interest

Every ten years, the United States “constructs” itself politically. On a decennial basis, U.S. Congressional districts are quite literally drawn, physically constructing political representation in the House of Representatives on the basis of where one lives. Why does the United States do it this way? What justifies domicile as the sole criteria of constituency construction? These are the questions raised in this article. Contrary to many contemporary understandings of representation at the founding, I argue that there were no principled reasons for using domicile as the method of organizing for political representation. Even in 1787, the Congressional district was expected to be far too large to map onto existing communities of interest. Instead, territory should be understood as forming a habit of mind for the founders, even while it was necessary to achieve other democratic aims of representative government.
