Urbanisation Footprints and the Distribution of Air Quality in Nairobi City, Kenya DOI:  https://doi.org/10.30564/jees.v3i2.3289 Abstract Various postulations on the relationship between urban morphology and air quality are qualitative. This fails to establish the strength of the contributions of each morphological parameter in the spatial distribution of the air quality. It is this gap in knowledge that this study sought to fill by modelling the correlation existing between the urban morphological variables of development density, land uses, biomass index and air quality values of Nairobi city. While 30 development zones of the city constituted the target population, IKONOS satellite imagery of the city for the year 2015 was utilised in establishing the development densities, land uses and biomass index. The parameters were transformed into numerical surrogates ranging from 1 to 10 with lower values accorded to zones with low biomass index, the highest development density, noxious...

Environmental Problem Analysis and Policy Recommendations on Pacific Northwest Salmon DOI:  https://doi.org/10.30564/jees.v3i2.3284 Abstract Environmental issues are becoming hot topics nowadays. As the steps of industrialization and urbanization expand, the conflict between economic development and environmental protection appears to intensify and catch people’s eyes more frequently, from the disappearing Amazon rainforest to the pollution of Mississippi River. Over the past few months, the news of one species, salmon, dying out in the northwestern part of the United States drew our team’s attention. In this paper, I would like to present my research on Pacific Northwest salmon from the perspectives of problem statement, policy proposal, and political analysis. Keywords:  Environmental problems, Pacific northwest salmon, Policy proposal, Political analysis

Sequential Damming Induced Winter Season Flash Flood in Uttarakhand Province of India DOI:  https://doi.org/10.30564/jees.v3i2.3069 Abstract 204 persons were killed while two hydropower projects located in close proximity at Rishiganga (13.2 MW), and Tapoban (520 MW) were damaged in Dhauliganga flood of February 7, 2021 in the Indian Himalaya. This incidence occurred during the winter season when the discharge of the glacier fed rivers is minimal, and no rain was experienced in the region around the time of the flood. Despite discharge of the main river, Rishiganga, not involved in the flood due to damming upstream of its confluence with Raunthi Gadhera, based on field evidences massive volume of around 6 million cu m water involved in this flood is attributed to sequential intermittent damming at three different places; (i) Raunthi Gadhera was dammed first in its upper reaches, (ii) Rishiganga river was then dammed to the north of Murunna, and (iii) finally Dhauliganga river was d...

Optimizing the Asset and Liability Management of Telecommunication Company using Goal Programming Model DOI:  https://doi.org/10.30564/jeisr.v2i2.2497 Abstract Since the telecommunications companies experience great competition, high churn rate, data traffic issues during the Covid-19 pandemic and the upgrade to 5G connectivity, the finance management of a telecommunications company should be analyzed to study the volatility and returns in the sector. This paper aims to develop a goal programming model to examine the asset and liability management of a telecommunication company, namely Telekom Malaysia Berhad (TM) in Malaysia. The result of this study shows that TM has achieved all the goals in maximizing assets, equities, profits, earnings and optimum management item while minimizing liabilities over the period of study from 2015 to 2019. Potential improvements on these goals have also been identified through this study. This paper has also contributed to the studies in financial ...

Exploratory Study on the Simulated Police Force Allocation of Shopping Mall Emergency Based on AnyLogic Platform DOI:  https://doi.org/10.30564/jeisr.v2i2.2417 Abstract Due to the rapid development of society, public places, especially large shopping malls, are relatively frequent places for emergencies. Such emergencies not only seriously affect public security and property, but also bring great psychological pressure to citizens. Therefore, this study is of great significance for the exploration and study of public place emergencies.The research object of this study is the public shopping mall. Based on the AnyLogic simulation platform and guided by the relevant principles of social force model, this study utilize the pedestrian storehouse in the platform as the core module to build the simulation environment, and attempts to simulate the police force restraining effect on the overall event and the perpetrators after the occur of emergent incident under different police force all...
