Some of the renowned world tourism countries have special peculiarities in character in terms of their nature reserves and built environments; that made them stand out for their attractions and visits. These qualities range from conservation and preservation of nature reserves, built environments- epoch architectural supports over the years; historical heritage; political; religious; socio-economic; cultural; and  high technology that enhance culture. The virtues of multi- ethnic groups and multi- cultural nature gave Nigeria a rich cultural heritage, and she is blessed with natural wonders, unique wildlife, and a very favorable climate. More often than not less attention and importance are placed over the nature reserves and built environments to the detriment of tourism in lieu of other sectors. Summarily the country lacks the culture of conservation and preservation of her abundant resources to promote cultural tourism. Case study strategy was applied in the research tours with reports of personal experiences, documentaries and analyses of sites visited in Europe and Nigeria were highlighted with references to their attributes in terms of structures and features that made up the sites as relate to culture and attraction.The task in keeping rural, city landscapes and nature reserves alive stands out as the secret of communication link from the past to present and the future; which tourism developed nations reap as benefits for tourist attraction.

The objective of this paper is to demonstrate the application of the Autism ASPECTSS™ Design Index in the Post-Occupancy Evaluation of existing learning environments for children along the autism spectrum. First published in 2014 this index outlines 7 design criteria that have been hypothesized to support environments conducive of learning for children with autism spectrum disorder (ASD). Using the index as a framework, this paper outlines a case study of a Post-Occupancy Evaluation (POE) of an existing pre-K-8th grade public charter purpose-built school for children on the autism spectrum. The tools used for the evaluation were: the ASPECTSS scoring of the school through a survey of teachers and administrators; on-site behavioral in-class observation; and focus groups of parents, teachers, staff and administrators. The results informed a design retro-fit proposal that strived to assess any ASPECTSS compliance issues and implement the index across the learning spaces, therapy spaces, support services and outdoor learning environments of the school. This paper will outline the application of the index and the resultant design from this process. The results will strive to present a scalable and replicable methodology and prototype for improving existing built environments for learners with ASD.

The recent discovery of a pit house village, 40 km northwest of Monterrey, challenges the conventional view of inland northeastern Mexico as the domain of purely nomadic hunters and gatherers throughout prehistory. Las Casitas consists of fifty-three subterranean rooms and forty-eight smaller depressions aligned in three slightly arcuate tiers in a small valley adjacent to Boca de Potrerillos, an extremely large open campsite and petroglyph complex that is now an archeological park. Other features of the site are some 325 hearths that surround the depressions and a very limited artifact assemblage numbering only thirty-seven items. Two hearths produced radiocarbon samples that date site occupancy to approximately a.d. 1450, just prior to the arrival of the Spanish in the New World. Las Casitas provides the first evidence of semi-sedentary, surplus producing populations in central northeastern Mexico.

AbstractIn urban renewal processes, metro line systems are widely used to accommodate the massive traffic needs and stimulate the redevelopment of the local area. The route choice of pedestrians, emanating from or going to the metro stations, is influenced by the street-scale built environment. Many renewal processes involve the improvement of the street-level built environment and thus influence pedestrian flows. To assess the effects of urban design on pedestrian flows, this article presents the results of a simulation model of pedestrian route choice behavior around Yingkoudao metro station in the city center of Tianjin, China. Simulated pedestrian flows based on 4 scenarios of changes in street-scale built environment characteristics are compared. Results indicate that the main streets are disproportionally more affected than smaller streets. The promotion of an intensified land use mix does not lead to a high increase in the number of pedestrians who choose the involved route when traveling from/to the metro station, assuming fixed destination choice.
