Budaya, Store Atmosphere Dan Kualitas Produk Terhadap Perilaku Pembelian Batik Di Toko Kawasan Kampung Batik Laweyan

The research aims to find out and describe the influence of simultaneously or partial culture, store atmosphere and product quality to Batik buying behaviour in Batik Store Laweyan Region. This methodology research using quantitative descriptive research. The population was all consumer Batik Store Laweyan Region unknown number. The number of samples was determined with the formula Lemeshow and the result 100 respondents. Sampling method using insidental sampling. The questionnaire used for data retrieval. Data analysis technique used was statistic analysis is multiple linier regression, F test, t test and determination coefficient. This test results the culture, store atmosphere and product quality simultaneously and significance effect on Batik buying behaviour in Batik Store Laweyan Region. culture influential positive and significance effect against the Batik buying behaviour in Batik Store Laweyan Region. Store atmosphere influential positive and significance effect against the Batik buying behaviour in Batik Store Laweyan Region. Product quality influential positive and significance to Batik buying behaviour in Batik Store Laweyan Region The results of the determination of the coefficient indicates culture, store atmosphere and product quality have influence of 57,2% cloth’s buying behaviour in Batik Store Laweyan Region. Suggestion in this research is company should improve the quality of product, espcecially about the characteristics of the product. Companies must be more varied in designing clothes so consumers are interested and purchases by consumers will increase. Keywords: Buying Behaviour, Culture, Store Atmosphere, Product Quality

Concerted rate-limiting proton transfer to sulfur with nucleophilic attack at phosphorus — A new proposed mechanism for hydrolytic decomposition of the P=S pesticide, Diazinon, in moderately acidic sulfuric acid media

We report herein the first kinetic study of a P=S containing organophosphorus pesticide, Diazinon (1), in the moderately concentrated acid region. Product analyses (31P NMR) show that reaction occurs only at the P centre. The rate-acidity profile (kobs vs. molarity of H2SO4) appears as a curve in which the initial slight downward trace (molarity = 1 to ca. 5) is followed by sharper upward curve (molarity ca. 5 to 14). Using treatments involving the excess acidity (X) method, the A-1 and A-2 mechanistic possibilities were found to be inoperative over the full acidity range. A novel mechanism is proposed for the higher acidity (X ca. 2–6) region. This mechanism involves proton transfer to P=S from hydronium ion with concomitant proton transfer from water, which effectively delivers hydroxide to the P centre in a variant of the A-SE2 process. A putative A-2 mechanism in this region is supplanted by the proposed A-SE2 variant where the cyclic array results in proton transfer being efficiently coupled with nucleophilic attack involving water. This constitutes the first report of rate-limiting proton transfer at the P=S functionality in acid hydrolysis of this class of organophosphorus neutroxins. A 600 000-fold acceleration in the decomposition of Diazinon is associated with the change of medium from neutral aqueous solution to the most acidic medium studied (X ca. 6). Key words: phosphorothioate ester hydrolysis, acid catalysis, rate-limiting proton transfer at P=S, excess acidity analysis, new A-SE2 variant mechanism.

A Risk-Return Model for Multiregion and Multiproduct Diversification of the Firm

The purpose of this paper is to demonstrate that the integration of locational considerations into product-diversification planning has the potential of supplying gains to the firm by providing hedges against both product-portfolio and location-portfolio risk. An efficient diversification frontier for region – product strategic planning is generated from hypothetical data for purposes of illustration. Results of the analysis are in agreement with Wahlroos's theory of the diversification of the firm.

Cloned cytotoxic T lymphocytes that recognize an I-A region product in the context of a class I antigen.

Cloned CTLs QM3 and QM7 isolated from a bulk CTL line B10.QBR anti-B10.MBR recognized a combination of the H-2Kb molecule and an I-Ak subregion gene product. Such a combinatorial specificity was revealed by complementation of the target antigen in F1 animals between two negative parental strains carrying H-2Kb and I-Ak, respectively. We confirmed the involvement of the H-2Kb molecule by blocking killing with anti-Kb mAb and failure of certain mutant H-2Kb genes to complement with I-Ak to generate the determinant in F1 animals. Although the nature of the I-Ak subregion gene product is not definitive, there was a correlation between the expression of Ia antigens on the cell surface and susceptibility of the cells to lysis by these CTLs, suggesting that it is the classical I-Ak class II antigen.
