in Borsa Istanbul 100 index companies between the years 2010 and 2012. In order to test our hypothesis that the companies issuing corporate social responsibility reports have higher performance in terms of financial accounting ratios, we applied a logistic regression analysis. Corporate social responsibility was used as the dependent variable and financial performance measures, firm size, firm risk, and type of ownership as independent variables. We found that there was a significant relationship between

managers on the two anomalies. Employing the newly developed ‘twelve-month rolling’ reputation ranking approach, our study is the first to furnish a comprehensive ranking of all the issue managers with a substantial presence in Singapore. Based on a sample of 384 IPOs listed on the Singapore Exchange between January 1, 1997 and August 22, 2008, we find evidence of prevalent short-run underpricing and long-run underperformance in the domestic market. Our findings indicate that the IPOs backed by higher

Gel electrophoresis Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge. It is used in clinical chemistry to separate proteins by charge and/or size (IEF agarose, essentially size independent) and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge.[1] Nucleic acid

Spectrometry can be useful if you would like to identify molecules in a mixture, detect impurities in a sample, and analyze a purified protein. Mass spectrometry is in essence a method used for weighing atoms or molecules. A mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio of its ion. Ions are generated by inducing either the loss or gain of a charge from a neutral sample. Once formed, ions are directed into a mass analyzer where they are separated according to the

Table of Contents Executive summary The model used in the SERVQUAL states that there are three variables to measure service businesses: service quality, product quality and price/quality ratio. Another study done by Nassrin (2009) has found that there is a difference in the level of satisfaction of students from different academic levels about university restaurants.

Statistical analysis, even simple analysis as counting, requires that each characteristic to be studied be assigned a unique value. Sometimes, especially in qualitative research with small samples, this value can be a word or symbol. For example, the interviewers could assign the word yes or positive to the symbol “+” to indicate that a respondent liked a product, flavor, or company. For a computer to prepare summary statistics or conduct a statistically analysis, each measurement of the sample population
