The process that goes from prospective decisions (oriented to risks of maximum profits with respect to minimum insurance benefits) to delibe-rate actions (oriented by avoidance of failures, based on the systematization of errors and successes) is addressed in the present work, aiming to specify a model for the study of Internet entrepreneurship. A non-experimental study was carried out with a non-probabilistic selection of 135 entrepre-neurs. From a structural model, the reflective factor of the construct was found to be deliberate actions, but such findings are only applicable to the sample since the type of study, sampling, and statistical analysis suggest the contrast of the model in other scenarios would increase the percentage of the explained variance of its factors, that added to 57% in this case.

Objective – The aim of this article is to present evidence based methods for the selection of chemistry monographs, particularly for librarians lacking a background in chemistry. These methods will be described in detail, their practical application illustrated, and their efficacy tested by analyzing circulation data. Methods – Two hundred and ninety-five chemistry monographs were selected between 2005 and 2007 using rigorously-applied evidence based methods involving the Library's integrated library system (ILS), Google, and SciFinder Scholar. The average circulation rate of this group of monographs was compared to the average circulation rate of 254 chemistry monographs selected between 2002 and 2004 when the methods were not used or were in an incomplete state of development. Results – Circulations/month were on average 9% greater in the cohort of monographs selected with the rigorously-applied evidence based methods. Further statistical analysis, however, finds that this result can not be attributed to the different application of these methods. Conclusion – The methods discussed in this article appear to provide an evidence base for the selection of chemistry monographs, but their application does not change circulation rates in a statistically significant way. Further research is needed to determine if this lack of statistical significance is real or a product of the organic development and application of these methods over time, making definitive comparisons difficult.

Germanium Substrates

An experimental study is reported to characterise the femtosecond (FS) laser grooving process for Germanium (Ge) substrates. The effects of process parameters, including laser fluence, pulse repetition rate and scan speed, on the groove characteristics, material removal rate (MRR) and heat affected zone (HAZ) size are discussed. It is shown that with properly selected process parameters, high quality micro-grooves can be obtained on Ge wafers. Recommendations are finally made on the selection of the most appropriate process parameters for FS micro-grooving of Ge substrates.

As the level of Si-wafer surface directly affects device line-width capability, process latitude, yield, and throughput in fabrication of microchips, it needs to have ultra precision surface and flatness. Polishing is one of the important processing having influence on the surface roughness in manufacturing of Si-wafers. The surface roughness in wafer polishing is mainly affected by the many process parameters. For decreasing the surface roughness, the control of polishing parameters is very important. In this paper, the optimum condition selection of ultra precision wafer polishing and the effect of polishing parameters on the surface roughness were evaluated by the statistical analysis of the process parameters.

Effect of  role playing macro methods on children's speaking ability in group B in Nurul Rohmah Bekasi. This research is motivated by the lack of ability to speak children. This is because the method used in the learning process is more likely to use conventional methods. The selection of methods to role playing macro so that children can be motivated and interested in learning and can stimulate the ability to speak children. The population in this study were all children of group B in kindergarten Nurul Rohmah while the study sample was B3 group 11 children for the experimental group and B1 group 11 children for the control group. Data collection techniques through test techniques, and observation. Data analysis techniques used were descriptive statistical analysis and nonparametric statistical analysis. Based on the results of the Wilcoxon test calculation, the calculated T value is 66 and T table 11 then the results obtained T count (66)> T table (11) H1 is accepted and Ho is rejected means that there is an effect of role playing macro  methods on children's speaking ability. Whereas the calculated Z value obtained is 2.93 and 1.645 table Z then the result of Z arithmetic (2.93)> Z table (1.645) H1 is accepted and Ho is rejected which means that there is an effect of role playing macro method on children's speaking ability. These results indicate that there is a change in the value of the child's speaking ability before and after getting learning based on the role playing macro method.

The purpose of the experimental study was the selection of salt tolerant crops and the search for useful horticultural species for growing them on saline lands. The experimental study was conducted at the University of Algarve, Portugal, in a greenhouse. The following vegetable crops were selected for research: lettuce (Lactuca sativaL), New Zealand spinach (Tetragonia tetragonioides) and garden purslane (Portulaca oleracea). Experimental results showed that New Zealand spinach and garden purslane have high potential as species resistant to high salt content and are therefore recommended for cultivation in order to reduce soil salinity. The above crops, mainly New Zealandspinach, are good types of garden crops with high useful qualities and productivity. Therefore, it has been shown that this method is a clean and environmentally friendly tool to prevent salinization and maintain the sustainability of agricultural systems
