BACKGROUND AND OBJECTIVES: According to the path of economic growth theories, especially the introduction of endogenous growth theories to address the shortcomings of extrinsic theories, the economic systems in order to achieve long-term economic growth goals need to drive stimuli and improve endogenous components that originate, crystallize, and evolve within these systems. Some endogenous growth models have stated that one country could be more successful than another if it devoted more resources to innovation. So today, the study of how to create innovation in various economic systems has become a challenging issue in the world’s economic circles.METHODS: Using the Meta- synthesis method, 19645 sources were collected between 1997 and March 2020 related to the urban innovation system, and after 7 steps and classification of resources, finally, 10 sources were selected and based on the coding method, the ten mentioned sources were coded. The estimated kappa coefficient indicates the reliability of the selected codes.FINDINGS: The paradigm model of the urban innovation system was extracted based on the performed codes. This model can be used as a pivotal model in future studies.CONCLUSION: An innovation system that can be implemented and applied in urban geography overcomes many urban, regional, and even national problems. Since this study examines the theory of Urban Innovation System, it can be expected that the results of this study can bring a positive step to determine the specifications and measures needed to create, sustain, and expand urban innovation systems.

BACKGROUND AND OBJECTIVES: This study evaluated temperature and urban heat island variability in days of the week and weekends of Port Harcourt city, due to the continuous heat stress and resultant health disaster common in tropical countries such as Nigeria. METHODS: The data were generated from field observation and Satellite Remote Sensing using Google Earth Engine of Landsat 5, 7, and 8 thermal infrared sensors. Temperature data from the field were captured with LCD Digital Multi-Thermometer Loggers located at different land-use types of 35 sample points in wet and dry seasons. Analysis of Variance was used to establish the temperature difference between days of the week and weekend. FINDINGS: The rural site during days of the week had temperature of 29.30C and the weekend had 29.50C indicating a concentration of human activities at the rural fringes during the weekend. The temperature of Saturday and Sunday varied between 33.20C and 27.60C (5.60C) with an urban heat island difference of 1.90C. Saturday was the coolest day having 3.70C. During days of the week, Monday had the highest UHI of 70C with the least UHI of 4.20C recorded on Friday showing the coolest day. The temperature difference between days of the week and weekend was 0.20C and UHI variation of 0.40C indicating that days of the week were warmer. The result showed that temperature in days of the week and the weekend differed significantly. CONCLUSION: It was established that days of the week contributed 52% of the temperature condition of Port Harcourt city and weekend donated 48% showing that 3,095,342 occupants of the city experienced lesser thermal stress during the weekend. Thus, the study concluded that the temperature of urban areas decreased from the city center to the rural fringes. The land surface temperature indicated that the north-eastern part of the city was the warmest. The study recommends proactive city planning and management framework with effective urban greening implementation for a healthy city living.
