Three negative binomial （NB） regression models and three generalized negative binomial （GNB） regression models are built to prove that the interactive influence of explanatory variables plays an important role in fitting goodness. The effective use of the GNB model in analyzing the interactive influence of explanatory variables and predicting freeway basic segments is demonstrated. Among six models, the two models （one is the NB model and the other is the GNB model. ） which consider the interactive influence of the annual average daily traffic （AADT） and length are more reasonable for predicting results. Furthermore, a comprehensive study is carried out to prove that when considering the interactive influence, the NB and GNB models have almost the same fitting performance in estimating the crashes, among which the GNB model is slightly better for prediction performance.展开更多

Based on the profound effect of ecological ideology on urban park design, we stud- ied the evolution course of ecological ideology and the characteristics of the ecological ideology at different stages in the United States, and emphatically introduced the influence of ecological ideology on the planning and design of New York Central Park, with the aim to summarize the inspiration for the urban park design in China.展开更多

The polysemous character makes it sensitive and complex phenomena. For instance, value that is acceptable in the western part of Nigeria may be unacceptable in the north or east. This clearly implies that value, although may be of the people, is relative and subjective. This study made use of survey research design with a single research question set to guide it. Data were collected from 362 respondents who were purposively selected in the study area （Lagos State, Nigeria） as sample size. Data gathering were done on the field with the aid of questionnaire and analyzed with descriptive statistics. Specifically, a Table of frequency and percentage distribution was employed and scoring of variables was done vis-h-vis the responses of the consumers of staple commodities to look at the extent to which societal values have influenced product advertisements in the State. The Mean and standard deviation was calculated. The result of the study presented in Table 1 shows that all the societal values scoped for this study （culture, moral, religion, taste, language and color） influence consumers in one way or the other but the portrayal of religious design concept to influence consumers to patronize staple commodities ranked best of all. The study observed that of all the societal values traceable to advertising campaign in Lagos State, religion-inclined advertising designs are gaining a rising number of influences. It therefore concludes that religious and cultural designs, when appropriately applied help outdoor advertising to thrive well in Lagos State.展开更多

It is an analytic function of r for all values except at r = O, which is singular. By determining the equation of motion in this metric we can estimate how expansion of the universe may affect Pioneer＇s motion. Because the metric does not have any event horizon and so high potential regions are accessible, this may help us in better understanding AGN phenomenon.展开更多

A sample of 6,730 Arab youth age 15-24 years was selected from Kuwait, UAE, KSA, Oman, Qatar, Bahrain, Jordan, Tunisia, Libya, Morocco, Lebanon, Egypt, Gaza and Palestine and Syrian refuges in Jordan. A questionnaire of 43 items to measure radicalization was developed based on the literature review. A construct validity of the scale was estimated by calculating the correlation between radicalization scale and Low self-control scale and found a positive significant relationship （0.680, a = 0.000）, a sign of validity of the scale. A Reliability of the scale is strong and was estimated by Cronbach＇s alpha and was 0.947. An average of 46.6% of the participants was categorized as radicals with standard deviation of 12. Macro social factors explained 64% of the variance on radicalization. It has a significant impact on radicalization （F = 807.6, a = 0.000）. Each single variable has a significant impact. The analysis revealed three groups of macro determinants of youth radicalization were identified： （1） Geographic factors： state, region, and Arab spring; （2） Social factors： religion, religiously, feelings, LSE and LSC; （3） Human security： unrest, terrorism, democracy, corruption, human development, youth unemployment and employment rate. To alleviate the consequences of radicalization, prevention policies should take in account youth concerns as partners and victims of radicalization. Policies need to focus on radicalization pull and push factors on micro-meso-macro level.展开更多

While Omhedi was a contested site of conflict during the war of liberation and served as a stage for ethnographic tours and photography, it has in post-colonial period come to represent a segment of important local power as it is currently the seat of the new Oukwanyama kingship. The central aim of this paper is to explain the transformation of Omhedi as a site of＂spectacles＂ of culture during the colonial period and as the seat of Oukwanyama monarchy in post-colonial Namibia. It centrally asks how the colonial politics of the time influenced the way Omhedi was organized and accessed and the ways in which people attach meaning to and organize a sense of space and place in the postcolonial era. This paper is significant as it explores how political legitimacy can be reactivated at such a contradictory site of＂traditional＂ power like Omhedi and what meanings these hold in terms of access in postcolonial Namibia. I conclude by raising issues of the past with the restoration of the Oukwanyama monarchy and its installation at Omhedi after independence, posing key questions about shifts in political legitimacy in both the colony and the post-colony. My analysis utilizes theories on the important use of landscape as a physical ＂space＂ for living, but also as a ＂place＂ with its meanings and contributions to societal identity. Consequently the place identity is a particular element contributing to sense of place. I argue that there exists a sense of nostalgia that many Ovakwanyama people have for a precolonial past, and the Omhedi landscape serves that purpose. In analyzing these sentiments against the construction of Omhedi as a space and place, this highlights a sense of identity and belonging that many Ovakwanyama people have towards Omhedi in default of any site with deeper legitimation or authenticity.展开更多

Real estate price xs not only a profound role on the level of consumption of the residents, but a profound role on the steady development of the banking sector-based financial sector. Real estate price have a significant impact not only on the development ofmacroeconomic stability, but on the safety of financial system. Chinese economy is currently on the period of transition from investment and export promotion of economic growth mode to a demand-led growth, it is an important role to China＇s economic growth for sustained and healthy development of real estate market.展开更多
