Abstract

Credit sales in a company have greater risks than cash sales do. An excellent internal control is needed over the accounting system of credit sales, receivables and cash receipts to reduce the occurrence of these risks. This study aims to evaluate, identify weaknesses and limitations of internal control and suggests some improvements as needed. The methods used are literary study on books, textbook, and other related literatures; field research by interviewing the relevant parts and observing the company activities, forms and accounting records used.

Abstract

This article discusses about the influence of sinusoidal sandbars towards the amplitude of incident wave. sinusoidal sandbars may lead to Bragg resonance. Basically, when a wave meets a different depth, it will scatter into a transmitted wave and a reflected wave. Bragg resonance happens when the wavelength of incident wave is twice of the wavelength of the periodic bottom disturbance. We apply the multi-scale asymptotic expansion to obtain the results. Eventually we find that a larger amplitude disturbance leads to larger reflected wave amplitude. This result explains that the sinusoidal sandbars indeed can reduce the amplitude of incident wave and protect a beach from large amplitude incident waves.

Abstract

Large companies which are experiencing barriers in innovation often take a radical step to acquire knowledge, namely acquisition. Though innovation is not the only reason, acquisition will result in the company wishes to achieve competitive advantage affected by the creation of ideas, creativity and innovation. The three points can be achieved more easily when the knowledge sharing within the organization / company runs well. However, the acquisition maybe impacts as a counter-attack for the knowledge sharing culture both in the acquisitor and and company which obtains the acquisition. Therefore, a key to succeed the acquisition is a sharing culture among individuals within a company that runs well or even better. Individuals from the acquisitor and those of the company that obtains the acquisition can adapt to each other and have confidence in order not to hinder them to share knowledge. This study discusses in detail the potential impacts of an acquisition upon a knowledge sharing culture in a company.

Abstract

Investment is very popular nowadays to gain profits of the available property. Many investment portfolios are available but there are still a handful of users who have not been able to determine the best type of investment. Surely it would be very unfortunate if the property can not be well invested. Therefore, it is necessary to propose another alternative method that can determine the existing investment portfolio. This method begins by a process which details existing factors in every investment portfolio. Then, it takes intuition properly to give weight to the initial calculation. After that, it takes a Fuzzy concept as a tool to provide a numerical weight to each of the parameters. The final step is weighting process using Dempster Shafer method. With the use of three basic concepts, investors are expected to obtain objective and optimal computing results related to the profitable investment portfolio selection.
