AN ANALYSIS OF OKLAHOMA DIRECT MARKETING OUTLETS: CASE STUDY OF PRODUCE FARMERS' MARKETS

The objectives of this study are to examine consumer preferences among various marketing channels including direct marketing in Oklahoma, and to analyze the impact of various demographic variables on purchasing choice. Specifically, this research focuses on the links between demographic factors and shopping preferences. Data from consumers' survey in 21 farmers' markets in Oklahoma will be used to analyze consumer preferences using an ordered logistic regression analysis method. Farmers' market producers and market managers were also surveyed. The results of this study identify consumer characteristics that influence produce demand and consequently growers' return at Oklahoma farmers' market.Consumer/Household Economics,

The influence of e-learning towards metacognitive enhancement in mathematical problem solving

This research aims to observe the influence of e-learning on metacognitive enhancement in mathematical problem-solving. The e-learning environment would encourage students to play more active roles in their learning. This research involves the students of Mechanical Engineering Department enrolled in the subject of Engineering Mathematics 4. It was found that the elearning method gives positive impacts on students' learning process. Therefore, it is suggested for educators to apply this method in their teaching. This is a suitable approach for students to be involved actively during their learning process. The lecturers should be more creative and innovative to vary their elearning to be lively, interesting, suitable, challenging while being in line with the students' cognitive development to provide comprehensible input

Coefficient of normal restitution of viscous particles and cooling rate of granular gases

We investigate the cooling rate of a gas of inelastically interacting particles. When we assume velocity dependent coefficients of restitution the material cools down slower than with constant restitution. This behavior might have large influence to clustering and structure formation processes.Comment: 3 figures, Phys. Rev. E (in press

Drug and Environment Parameters of Pharmacy Places

This study consists of two parts; the first part is measuring the temperature and relative humidity of twenty pharmacy shops and pharmacy refrigerators in Erbil city. The temperature inside nine types of different drug bottles is also measured. The results show that temperature and humidity inside pharmacy places and refrigerators are higher than the standard temperature (25C) and relative humidity (35%) of drugs. The temperature inside the drug bottles would be higher if compared with environment temperature. Second parts, the optical properties of the drug bottles are studied by using UV-VIS spectrophotometer, where they are used to analyze the optical properties of the drug bottles. The result shows a maximum value of transmittance ranging from 0% to 88% depending on the types of the drug bottles. Optical transmittance of 25–88% in the visible range has been observed in all samples, high UV transmittance (5%-70%) in %77 samples and infrared (up to 38%-88 % are observed in %88 samples.)

Scaling of Star Polymers with one to 80 Arms

We present large statistics simulations of 3-dimensional star polymers with up to $f=80$ arms, and with up to 4000 monomers per arm for small values of $f$. They were done for the Domb-Joyce model on the simple cubic lattice. This is a model with soft core exclusion which allows multiple occupancy of sites but punishes each same-site pair of monomers with a Boltzmann factor $v<1$. We use this to allow all arms to be attached at the central site, and we use the `magic' value $v=0.6$ to minimize corrections to scaling. The simulations are made with a very efficient chain growth algorithm with resampling, PERM, modified to allow simultaneous growth of all arms. This allows us to measure not only the swelling (as observed from the center-to-end distances), but also the partition sum. The latter gives very precise estimates of the critical exponents $\gamma_f$. For completeness we made also extensive simulations of linear (unbranched) polymers which give the best estimates for the exponent $\gamma$.Comment: 7 pages, 7 figure
