Assessment of websites remains a definite challenge within advertisement research. In order to gather objective information, one possibility exists in using Eye-Tracking. This method allows for determination of where and how long particular areas of a website are fixed. However, longer fixation values do not necessarily reflect higher attention or even memorizing of the content. It could also mean that the content is too complicated. Therefore more information can be obtained by addition of quantitative analysis of brain electricity. Following the changes of the frequency content of electric brain activity has been recently introduced as “Neurocode-Tracking”. In the present study, quantitative assessment of websites has been performed by the combination of Neuro-code-Tracking with Eye-Tracking. Fast dynamic quantitative EEG recording with a time resolution of nearly 3 images/second provided electric power values according to frequency analysis in 17 brain regions (electrode positions). Particular values represented changes of electric brain activity, which were interpreted to represent visual perception, mental activation, concentration, stimulation, memory and tension according to earlier experience. Eye-Tracking was performed in a conventional manner by defining special areas of interest for detection of fixation lengths and time to first awareness. Ten male subjects (aged 36 ± 4.4 years) entered the study. They were asked to view Internet landing pages of five bank institutions: ComDirect, DKB, INGDiBa, Postbank and Targo-Bank. According to Eye-Track analysis, ComDirect was recognized to have the shortest time-to-awareness with respect to conditions, bonus, faces and application or address form. With respect to region of interest “service”, INGDiBa showed the shortest time-to-awareness. Neurocode-Tracking provided best results for INGDiBa with respect to mental activation and concentration. Stimulation and memory values were headed by Targo-Bank. Lowest tension was observed by the landing page of the Postbank. In summary, the combination of Neurocode-Tracking and Eye-Tracking provided much more information than any one of the methods used in separate. We therefore recommend this combination for the assessment and optimizing of Internet websites.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
