Kinetic surface roughening for the Mullins-Herring equation

Using the linearity property of the Mullins-Herring equation when the velocity is zero with a Gaussian noise, we obtain an analytic form for the global mean-square surface width and height-height correlation function. This can be used to read the critical exponents in any dimension. In particular for d=1 we show that although the surface is super rough the system exhibits Family-Vicsek scaling behavior.Comment: 5 page

A new approach for measuring human resource accounting

Significance of identifying human resource competency in organizations and the necessity for valuating human resource in accounting persuade many researchers to design a conceptual model for measuring human resource accounting. This study, first, examines dimensions of various valuation models of human resource and then they are compared with Goleman individual and social competency indicators. Next, individual, organizational and social competency indicators are designed through developing Goleman model. Finally, Analytical Hierarchy Process (AHP) and experts’ ideas in human resource accounting in superior universities of the world are used to classify the indicators; and the conceptual model of measuring human resource accounting is designed based on guidelines of management and human capital development vice-presidency and inspiring effort rate of return method

The impact of cultural distance on local residents perception of tourism development: The case of Dubai in UAE

This study discusses the importance of understanding cultural differences between tourists and hosts for developing positive cross-cultural tourist interaction and its influence on the host\u27s perception of sociocultural impacts of tourism. A logistic regression model is used to identify the significant positive as well as negative impacts perceived by hosts who view a significant cultural distance between them and tourists versus those who do not. It is found that there is a significant relationship between the perceived cultural differences and the perceived sociocultural impacts of tourism. The majority of respondents who do not perceive cultural differences agree to most of the perceived positive impacts of tourism. The results of running the regression model have identified improved quality of life as the largest positive impact. Becoming more proud of their city comes next, then improved infrastructure, followed by an increased variety of leisure attractions, and lastly more shopping varieties and facilities. On the other hand, the study found that higher prices for goods and services are the largest perceived negative impact. Tourist\u27s failure to respect local customs and moral values comes next, followed by community conflict and tension, then loss of cultural identity, and increased crime. The implications of the results for tourism industry managements and marketers are presented as well as areas for future research
