The use of written information in planning is important in making one's business competitive and profitable. This study sought to understand and explore the situation among some small business operators in Jamaica's two primary cities. It is based on a Master's research paper undertaken at the University of the West Indies, for the Masters in Library and Information Studies. The study collected data between 2005 and 2006 using survey techniques. The data was then analysed in relation to the researcher's question. The findings indicate that written information are important in the operations of Jamaican small business operators. While written information sources are used by most small business operators to inform their business planning processes, many are not sufficiently benefiting as they could from written information sources due to a variety of reasons. A number of recommendations are made to improve this situation. This book is relevant to those who undertake specialist publishing and information dissemination for small business operators. It is also relevant to those seeking important sources of Jamaican business information for planning.

Polypropylene (PP)/Calcium carbonate (CaCO ) nanocomposites intend to become a cost effective alternate solution to engineering thermoplastics if good dispersion is achieved. In this work, CaCO with micro and nano median particles sizes with and without surface treatment were added to polypropylene. SEM image analysis was used to obtain the particle size distribution of CaCO nanoparticles after mixing. The Gamma Variate function was found to fit the particle size distribution with a correlation coefficient above 0.99. X-Ray diffraction was used to calculate the k parameter to quantify the -iPP in the composites. Based on this parameter, CaCO nanoparticles were more effective promoting the formation of -iPP than microparticles. The tensile test showed higher elastic modulus and tensile strength with addition of nanoparticles. Impact strength was higher with the addition of microparticles. However, surface treated nanoparticles at 2wt% and 5wt% compositions and high k increased the impact strength of PP above 40% compared with neat PP. The best combination of mechanical properties was found for PP nanocomposites filled with 2wt% of 0.07 m treated particles and k=0.22.
