Authors:David Ngwoke Mbazor; Clinton Ohis Aigbavboa , Wellington Didibhuku Thwala Abstract: Nowadays, there exists a high incidence of competitions between organizations seeking control, relevance, and dominance in the market space due to globalization exacerbated by the continuous advancement in technologies, high customers’ tastes, and expectations. This has significantly influenced organizational decisions leading to constant reevaluation of operational procedures, adopting and implementing changes that will influence positive business outcomes. The literature search revealed that past studies on organizational leadership focused mainly on elements of leadership styles, strategies, and ethics. Hence, studies have not identified the factors that influence organizational leadership for adequate housing delivery in Nigeria. The study identified the factors that influence organizational leadership in the delivery of housing in Nigeria using the Broaden and Build theory, and Kurt Lewin’s leadership philosophical concepts as the fundamental basis underpinning the study. Delphi study approach was used to determine the areas of commonality before a consensus was reached. A structured questionnaire was administered to validate and removing outliers from the result. The Delphi study identified 20 distinct factors that influence organizational leadership for AHD in Nigeria. Factors such as organizational sustainability, motivation, etc., are the most significant factors influencing organizational leadership towards AHD. However, results from SEM analysis showed that only 12 variables are significant in measuring organizational leadership and management for AHD. The study concludes that the 12 identified factors are significant in AHD. Nevertheless, the application of these factors in housing delivery is still low in Nigeria. Hence, it is recommended that real estate developers and other operators in housing should use the result from this study as a template for developing adequate housing.

Authors:Nathaniel Oluwaseun Ogunseye Abstract: Globally, development control is one of the main activities of the planning agencies aimed at ensuring sustainable development in human settlements. Previous studies primarily explored compliance with planning regulations whereas issues of awareness, satisfaction, and willingness to participate have not been adequately dealt with. This study evaluates the property developers’ experiences with the planning approval process (PAP) in southwestern Nigeria. The specific objectives are to (i) probe property developers’ awareness of the legality of the PAP, (ii) examine property developers’ satisfaction levels regarding the PAP, (iii) determine property developers’ willingness to participate in PAP discourse, and (iv) examine problems associated with the PAP. Purposive and convenience sampling techniques were adopted to elicit data from 96 respondents using a structured questionnaire. Data were analyzed using both descriptive and inferential statistics. Major findings showed that 68.8% of the developers were aware of the legality of PAP, 70.8% expressed satisfaction with the PAP, and 78.1% were willing to participate in public discourse about PAP. Fishers’ Exact test revealed that the location of developers (χ2= 6.907, p=0.025) and gender (χ2= 0.000, p=0.023) were significantly associated with developers’ awareness of the legality of PAP. The Spearman Correlation test indicated a significant association between developers’ satisfaction with PAP and their support for seeking planning approval (r=0.339, p=0.001) as well as planning approval processing time (r=0.250, p=0.026). The study recommends aspects of PAP the planning agencies need to improve upon towards achieving sustainable PAP. The study outcome will be useful for policy formulation in areas of education and awareness creation, planning approval processing time, and procuring documents required by the planning agencies. Addressing these issues will mean property developers will derive greater satisfaction from planning agencies’ services and will be inspired to participate in planning matters.

Authors:Hilal Kahveci; Makbulenur Onur Abstract: The Covid-19 pandemic, which emerged in Wuhan city of China's Hubei province in December 2019, affected the whole world in a short period of 3 months. The Covid-19 outbreak, which was declared a pandemic by the World Health Organization as of March 12, 2020; was imposed significant restrictions on the use of open spaces, which adversely affected the daily life of individuals physically, mentally and socially. Apart from the health problems experienced by people, it has also created many spatial choices and changes. New preferences, where social distance is at the forefront, have started new venue organizations along with new requests. Although the changes experienced with the Covid-19 pandemic may seem negative, they contain opportunities that allow change and development. Making people's living environments more functional, remembering the importance of nature and reviewing social relations can be evaluated in this context. Looking from history to the present, the Covid-19 pandemic is not the first and will not be the last. For this reason, the study aims to investigate the change in the spatial preferences in the society with the pandemic and to create an idea for the next pandemics. In this context, 289 people were reached by using the online survey method and various questions were asked. Various results were obtained and interpreted by performing variance analysis, factor analysis, correlation analysis, crosstabs test and frequency analysis (P˂0.01) on the obtained data. As a result of the study, from the statistical data, it has been observed that 'people are more oriented to nature' due to the Covid-19 pandemic and that open green spaces suitable for social distance are sought in spatial preferences. These findings shed new light on the value of urban nature as resilience infrastructure during a time of crisis. PubDate: Thu, 29 Dec 2022 00:00:00 +080
Authors:Amos Mafigiri; Mohd Faisal Abdul Khanan, Ami Hassan Che Din , Muhammad Zulkarnain Abdul Rahman Abstract: This study sought to assess the influence of causal factors related to anthropogenic activities on landslide occurrence in Bukit Antarabangsa, a township northeast of Kuala Lumpur in Ampang Jaya Municipal Council. Anthropogenic factors were chosen based on the township’s rapid growth, numerous landslide records and intensity of hillside development. The study used a data-driven statistical model to identify factors most predictive of landslide occurrence based on an inventory of 20 landslides, and to evaluate the extent to which susceptibility was driven by factors related to urban development. A total of 17 factors were categorized into four clusters (geological, geomorphological, hydro-tographical and anthropogenic). Factor maps were classified to derive factor classes for each parameter. The dataset was then processed using a weight-of-evidence statistical model to determine the contrast value of each factor class. Contrast value (C) reflects the extent to which each factor class predicts landslide occurrence. The C-weighted factor maps were then combined to derive the landslide susceptibility index (LSI). The LSI enabled visualization of the spatial distribution of susceptibility based on a given combination of factors. Susceptibility maps were prepared for combinations containing only non-anthropogenic parameters and all landslide parameters. The study compared these combinations to determine the influence of anthropogenic factors on total LSI. Similar analyses were conducted to determine the effect of each anthropogenic factor on LSI. The results indicated that lineament density, distance to lineament and distance to road had a significant influence on landslide occurrence. A strong correlation with landslide occurrence was observed for land use/land cover, especially in high susceptibility zones, followed closely by the influence of one distance to road factor class. The results could be useful in planning infrastructure corridors in densely built-up landslide-prone areas. PubDate: Thu, 29 Dec 2022 00:00:00 +080
Authors:Githmi Abeysooriya; K.G.P.K. Weerakoon Abstract: Dried fish manufacturing is a famous cottage industry in Sri Lanka. Due to various natural and manmade reasons, their locations are not set up in sustainable ways. As a result, industry locations have become more vulnerable. Therefore, hurdles are there to sustainably expanding this cottage industry. So, the industry's novelty and the enormous number of issues experienced have yet to be discovered or solved via research study. Therefore, the current study intends to conduct GIS-based vulnerability analysis of the fish drying cottage industry by identifying the socioeconomic, environmental, and industry-related backgrounds of existing manufacturers and the industry, challenges faced by manufacturers, and vulnerable sites in the village using geo-spatial analysis. The case study focuses on Kudawella of Tangalle local authority, in the southern province of Sri Lanka. Qualitative analysis was used to identify the existing situation using a structured questionnaire survey and descriptive analysis was performed on the obtained information. The constraints were revealed by a content analysis of qualitative data acquired from a judgemental sample via semi-structured and unstructured interviews. Furthermore, the relative positions of the cottages were determined using OpenStreet Map and the absolute coordinates of a sample of 27 cottages gathered using GPS. A Weighted Overlay Analysis was performed using Arc Map 10.8 to create a Vulnerability Index Map to identify vulnerable locations for the industry while taking nine socioeconomic and environmental parameters. The outcome indicated four categories of vulnerability: severe, moderately severe, moderate, and low vulnerability, with 4.13% of the village falling into the severely susceptible category. The index map assists relevant authoritative organisations in making industrial decisions to attain sustainability based on the amount of risk and underlines the importance of institutional and individual decision-making systems PubDate: Thu, 29 Dec 2022 00:00:00 +080
Authors:Sanusi Sani Maimagani; Roshida Abdul Majid , Leng Pau Chung Abstract: Permeation of heat into the school building enclosure through external walls components of the building resulting into the numerous consequences which causes unhealthy indoor living conditions for teaching and learning activities, which has a negative impacts on the students general academic performance and their productivity, the study carried out a fieldwork experimentation where four experimental models (chambers) were built using four dissimilar compressed earth (C.E.B) configurations; compressed earth horizontal hollow brick (C.E.H.H.B), compressed earth vertical hollow brick (C.E.V.H.B), compressed earth cellular brick (C.E.C.B), and compressed earth solid brick (C.E.S.B) respectively, data were collected from fieldwork experimental chambers using two distinct wall surface temperature measuring devices; an onset UX120-M600 4-channel analogue data logger and Testo 835 Infrared thermometer which were utilized to measure the interior wall surface temperature facing the west direction of each experimental chamber to determine the rate of thermal admittance of the entire chambers built with distinct C.E.B configurations, the extracted data using surface temperature measuring instrument were analyzed using the spss software package for identification of the C.E.B configurations with the least thermal permeation from outdoor environment to indoor space of the school building via external walls of the building. After the statistical analysis, the study's outcome revealed that compressed earth horizontal hollow brick (C.E.H.H.B) has a minimum heat transfer rate of (34.933OC) and (35.7493OC), among other C.E.B configurations. This undoubtedly indicated the appropriate C.E.B configurations for school buildings in hot-dry climate regions of northwestern Nigeria. PubDate: Thu, 29 Dec 2022 00:00:00 +080
