The aim of this study is to identify the link between online sales systems, infrastructure, ease of use & information accuracy in improving Jordanian restaurants’ call centers' performance effectiveness (JRCCPE). In order to achieve the study's objectives, a questionnaire was conducted for measuring the link between online sales systems (OSS), infrastructure, ease of use & information accuracy in improving JRCCPE. The study sample was selected by distributing 220 questionnaires to all employees of Jordanian restaurants’ call centers (JRCC) from the set of employees working in an online sales system where 173 were retrieved. Aiming to answer the study questions and test hypotheses, the researcher extracted the means and standard deviations to apply the multiple regression equation. Accordingly, the study reached many results, showing a statistically significant effect for using the OSS, infrastructure, ease of use & information accuracy in improving JRCCPE. The study suggested that JRCC seeks adding various characteristics of editing, deleting, copying, and setting the time on the basis of text messaging through such networks as well as the need to conduct marketing studies in order to enable companies to achieve the customers' wishes in a method matching their expectations.

In this paper, an attempt is made to develop two inventory models for deteriorating items with variable demand dependent on the selling price and frequency of advertisement of items. In the first model, shortages are not allowed whereas in the second, these are allowed and partially backlogged with a variable rate dependent on the duration of waiting time up to the arrival of next lot. In both models, the deterioration rate follows three-parameter Weibull distribution and the transportation cost is considered explicitly for replenishing the order quantity. This cost is dependent on the lot-size as well as the distance from the source to the destination. The corresponding models have been formulated and solved. Two numerical examples have been considered to illustrate the results and the significant features of the results are discussed. Finally, based on these examples, the effects of different parameters on the initial stock level, shortage level (in case of second model only), cycle length along with the optimal profit have been studied by sensitivity analyses taking one parameter at a time keeping the other parameters as same.

The immobilized NaHSO4·H2O on activated charcoal was used as a highly efficient promoter system for facile N-formylation of amines with ethyl formate. All reactions were carried out in refluxing ethyl formate (54 ?C) under mild conditions within 10-100 min to afford the product formamides in high to excellent yields (80-94%).

This paper examines the impact of economic and financial factors on tax revenue of Bahrain and Oman from 1990 to 2010. For this purpose, panel regression analysis is performed by considering economic and financial factors including growth domestic product (GDP), Deposit Interest Rate, Lending Interest Rate, Interest Rate Spread, Real Interest Rate, Bank Capital to Asset Ratio, Bank nonperforming loans to total gross loans, Risk premium on lending, Foreign direct investment net inflow and Cash surplus deficit. A conceptual model is developed for this purpose and the key findings are explained. The outcomes of the study explain that there was a significant relationship between Tax revenue and both economic and financial factors i.e. GDP growth, Bank capital to asset ratio, the Risk premium on lending, Foreign direct investment net inflow and Cash surplus/deficit over the period of study. The findings of the study are very much useful for the policymakers to consider which factors are affecting the tax revenues and in which direction. However, the findings of the study can be more meaningful with the addition of more economic and financial factors as well. Besides, the consideration of other Asian states will provide more evidence for the generalization of the findings. Meanwhile, this study will be a policy note on on-going tax reforms in selected Middle East countries and will be helpful for policymakers and researchers in conceptualizing the tax revenue model for them.

The footwear industry is booming with the increasing demand for leather-based products and manufacturers from the Asia region are leading the market. In the meantime, the negative impact on the environment of footwear goods and manufacturing processes of footwear-based products concerns the buyers and consumers as the global environmental situation is worsening day by day. For this reason, footwear industries are bound to use environmentally friendly production techniques to cope with the conditions as well as demands of the buyers otherwise the manufacturer can face the drop of order which can be affected financially. The Bangladeshi footwear industry is most unlikely to adopt sustainable manufacturing and thus lagging in the competitive market containing manufacturers from other Asian countries. The reason behind not implementing sustainable manufacturing practices should be explored to ensure this practice. In the study, Graph Theory and Matrix Approach (GTMA) was utilized along with the best and worst matrix using the weighted values as the diagonal and off-diagonal elements which was found from the two surveys after consultation with experts from the Bangladeshi footwear industry to gather responsible barriers for both large-scale and small-medium sized enterprises. Ranking based on impact was developed for two scales and an index value was found from the calculations of the matrix formed by permanent functional value found for each of the barriers and their best-worst values also which was another determinant of this study for expressing the fitness level for this certain adaptation. Similarity coefficient was another factor to be determined for the decision making required for the first objective of this research.

The E-1,3-diaminoethenyl functional group is a potentially useful synthon. A number of examples of E-1,3-diaminoethenyl functional groups were prepared in good yield starting from an E-enol tosylate of a serine based diketopiperazine and 1°- or 2° amine nucleophiles. The reaction proceeds via a stereoselective nucleophilic substitution pathway.

The present study examined the effects of cashless policy on financial inclusion in the Nigerian emerging economy. The necessary data were collected from the Central Bank of Nigeria Economic Reports as well as Statistical Bulletin and the ordinary least squares method was applied to analyze the data. The findings reveal that the cashless policy maintained a non-significant relationship with financial inclusion both in urban and rural areas of Nigeria. The findings show that the cashless policy had a significant effect on increasing customers’ deposits in commercial banks of Nigeria. Volume of Automated Teller Machine (ATMVL) maintains a positive and significant effect on financial inclusion indicators in urban center compared with the rural areas. Volume of Point of Sales (POSVL) shows more significant and positive influence on financial inclusion in urban area than the rural area. However, Web Based Technique (WBTVL) reveals a non-significant effect on financial inclusion both in urban and rural centers. The study therefore recommends that more branches of commercial banks and ATM centers/outlets should be opened in rural urban centers with efficient network systems and security in order to enhance banking penetration and by extension effectiveness of the financial inclusion and poverty reductions.

The purpose of the current study is to investigate the various factors influencing on people to invest in mutual funds and examine the mediating role of investor’s perception. By using quantitative research approach and cross-sectional research design, 300 questionnaires are distributed among the individual investors and Smart PLS 3 is used to analyze the data. The results reveal that risk and return, liquidity of assets, demographic factors (gender, age, and material status), convenience, reduction in transection cost, tax benefits and transparency were the key factors and maintained significant relationships with investment in mutual funds. Moreover, investor’s perception maintains mediating role between all these factors and investment in mutual funds. The study contributes in literature by investigating the various factors, which influence on investors to invest in mutual funds. Moreover, it also contributes by investigating the mediating role of investor’s perception.

A series of new Schiff bases of 4-(methylthio)benzaldehyde derivatives 3(a-i) were synthesized by the reaction of 4-(methylthio)benzaldehyde with various amines 2(a-i). Newly synthesized compounds were characterized by elemental analyses, UV-visible, FT-IR, Mass and 1H NMR spectral studies. All compounds were evaluated for their in vitro antibacterial activity against clinically isolated strains i.e., E. Coli, P. Fluorescence, M. Luteus and B. Subtilis. These compounds were screened for their antioxidant activity by 2,2-diphenyl-1-picryl-hydrazyl (DPPH•) and ferrous ion chelating assay (Fe2+) methods. The cytotoxicity assay was performed by tryphan blue dye exclusion method. Compounds 3g, 3h and 3i exhibited good antibacterial activity when compared with other compounds in the series against tested pathogenic bacterial strains. All the compounds showed antioxidant activity, where compound 3b was the best radical scavenger and Fe2+ ion scavenger. These findings showed that the Schiff bases of 4-(methylthio)benzaldehyde derivatives possess antioxidant activity with different mechanism of actions towards the different free radicals tested. Among these derivatives, 3b and 3h had the strongest activity against human peripheral lymphocytes.
