An enterprise-development strategy for Zambia

Although Zambia's deteriorating macro-economic situation has created a difficult environment for business, it also creates opportunities for the emergence of small and micro enterprises. Recent government policy reforms affecting these firms are discussed, along with existing programmes for credit, training, technical assistance, and common-site facilities/business incubators. The current programmes are limited in scope relative to the potential demand, and qualitative improvements are needed. Time-phased options for assisting small and micro enterprises are discussed.     

Aromatic content in medium range distillate products--Part I: an examination of various liquids

Classification of ignitable liquids in accordance with voluntary consensus-based standards published by ASTM International has become increasingly specific, relying upon both the chemical composition and the boiling point range of submitted ignitable liquids. This classification system includes among others, specific classes for distillates and dearomatized distillates. In this study, a variety of medium-range ignitable liquids were analyzed by gas chromatography-mass spectrometry. Several methods of data analysis were utilized to examine the relative aliphatic and aromatic contents in these liquids. Results show that commercially available products in the medium range exhibit a broad range of compositions with respect to the relative proportion of aliphatic and aromatic compounds and that some liquids may not be easily classified. This study demonstrates the importance of examining the proportion of aliphatics:aromatics for classifying such liquids and suggests guidelines for differentiating medium range distillates, dearomatized distillates, and blended products.     

Evaluation of iodine-benzoflavone and ruthenium tetroxide spray reagents for the detection of latent fingermarks at the crime scene

The performance of two spray reagents, iodine-benzoflavone and ruthenium tetroxide (RTX), was evaluated and compared with the conventional technique currently used at the crime scene, that is, powdering. Neither the spray techniques nor powdering were shown to be suitable for all surfaces and ages of marks tested. On some surfaces such as glass and treated wood, powdering was still the superior technique, whereas the spray techniques produced better development on wallpaper, vinyl, and brick. Sequencing work showed that RTX was incompatible with powdering and cyanoacrylate (with a rhodamine 6G stain). Iodine-benzoflavone can be used successfully either before or after powdering in a sequence; however, it was incompatible with cyanoacrylate. Two non-CFC formulations of iodine-benzoflavone using HFC4310mee and HFE7100 solvents were tested and shown not to be as effective as the original Arklone (CFC-113) formulation; however, the HFC4310mee solvent is recommended as the most suitable replacement solvent. Due to the expense of the commercial RTX spray, attempts at formulating a more cost-effective version were also carried out. A formulation was developed that gave comparable development to the commercial version but at a much cheaper cost, and with a shelf life of up to two months. Recommendations are presented for which techniques are suitable for different surfaces and ages of marks. Powdering was shown to be the best technique on all ages of marks tested on treated wood, glass, and also on marks aged three days and older on paint. Iodine-benzoflavone was the best technique on wallpaper, vinyl, brick, and raw wood. RTX was the best detection technique for fresh marks and marks aged up to one day on wallpaper and paint.     

Attempted suicide by cop: a case study of traumatic brain injury and the insanity defense

Over the years, there have been a number of well-publicized incidents involving persons who seemingly maneuver police officers into shooting them. Such cases, while relatively rare compared with most forms of violence, nevertheless pose difficult challenges to law enforcement agencies. Relatively little is known about persons who engage in suicide by cop incidents. To our knowledge, there has been no published indepth research on instigators of suicide by cop who survived. In this paper, we present a case study of an individual who engaged in and lived through three separate "attempted suicide by cop" incidents. After describing relevant history as well as events of the most recent incident, we compare the case with the extant literature on suicide by cop and analyze commonalities and differences. Finally, we examine the legal considerations involved, with particular attention devoted to the role the individual's traumatic brain injury played in applying the insanity defense.
