Defense Conversion in Small Companies: Risk, Activities, and Success Assessment

The defense industry has been experiencing a large draw-down during the 1990s. This has left many companies, large and small, in a situation where they had to examine the viability and future of their businesses. While large and medium-size companies were somewhat assisted by government policies and support, small subcontractors were often left alone, facing higher risks and severe threats to their future. This research investigated the events, decisions, activities and success of small defense contractors, which had to face this new situation. It developed a specific framework, which may be used to help companies in assessing their conversion efforts. The study was conducted by utilizing a within-case and cross-case methodology for case study analysis. Results assert the difficulties for highly defense dependent companies to enter and succeed in the commercial market and explain why many conversion efforts have often failed in the past. Our findings show that to convert successfully, companies must streamline and improve their internal processes, develop a strategic plan, develop their marketing capabilities, and must have management and employee commitment to the process. Although such recommendations were expected, we found, that to many of these companies, they were completely new. As a by-product to this study, we found that managers in small businesses are typically not aware of modern concepts of strategic management and do not normally read the management literature. A new approach to educating such managers is needed, and thus suggested.     

Determination of phosphoglucomutase phenotypes in hair bulbs

The research was to determine a simple method of phosphoglucomutase phenotype identification in hair bulb. The agarose technique and electrophoresis on cellulose-acetate foil methods were chosen because a small quantity of the maternal available for examination. It was found out that 1 or 2 bulbs are sufficient to identify the PGM1 features if the electrophoresis method is applied and if more bulbs are available, the PGM3 characteristic can also be identified. The modified technique was used for staining the phosphoglucomutase phenotypes.     

A comparative study of gunshot residue originating from 9 mm Luger ammunition from various producers

Following previous work on differentiation between gunshot residue according to the type of ammunition used, a specific investigation was undertaken of traces originating from 9 mm Luger ammunition using SEM-EDX. The aim of this study was to determine whether GSR originating from this type of ammunition is similar, or whether differentiation could be made between particular manufacturers of Luger ammunition. The results were collected in the form of counts of particles in each of seven key elemental classes being combinations of lead, antimony and barium. These were then adjusted to a factor known as frequency of occurrence which allows comparison of the distribution of particles within the classes between samples with differences in absolute particle counts. The relationships between the samples were examined using non-parametric statistical tests: R-Spearman and tau-Kendall rank correlation coefficients. It has been found that most of the studied samples of GSR were similar to each other despite their originating from various manufacturers.     

Poisoning by toxic plants in China. Report of 19 autopsy cases

In this article, we report on 19 autopsy cases in China in which the cause of death was poisoning by toxic plants. The emphasis is on analyses of the target organs or tissues affected by these plants. The mechanism of poisoning and cause of death are approached on the basis of the pathologic changes, and associated problems relating to forensic medicine are discussed.     

Radiograms of the paranasal sinuses as a principle of identifying catastrophe victims and unknown skeletons

The paper is devoted to the identification on the base of X-ray of frontal sinuses. These sinuses, developed in puberty doesn't change its shape during aging. Differentiation of the size and shape of sinuses is remarkable and probably is one of the individual features of the man. The system of classification of sinuses is proposed, basing on the area size, shape and symmetry. In the current everyday practice all X-ray radiograms are destroyed after five years of storage in Poland. For identification purpose all radiograms of sinuses and A-P punctures of skull should be stored in radiology departments, and arranged according to proposed classification system. The case is presented, in which the pictures of skull were the base of successful identification of skeleton.
