Investigation Study of the Challenges in Green Procurement Implementation in Construction Projects in UAE
Get PDFThe global construction industry is responsible for significant environmental and societal effects. Some researchers claim that it accounts for 35% of global gas emissions. One of the solutions is to practice green supply chain management. Part of this is Green Procurement (GP) to conserve energy and money. However, challenges in implementing green procurement in the construction industry are rising. This research aims to identify the most significant challenges when implementing green procurement (GP) in construction projects in the UAE. A comprehensive article review was conducted to determine the critical obstacles highlighted by different researchers. These challenges were prioritized using the analytical hierarchy process (AHP) method, and then recommendations on best practices to overcome these challenges were proposed. The results show that the lack of top management commitment is the biggest challenge when implementing green procurement in the construction industry in the UAE, with a priority value of 0.331, followed by a lack of knowledge, with a value of 0.2748. In contrast, lack of awareness is the lowest-ranked factor, with a value of 0.103. Doi: 10.28991/CEJ-2023-09-04-06 Full Text: PD

No full textMarkers of cardiac dysfunction such as amino terminal pro-brain natriuretic peptide (NTpro-BNP) and high sensitivity cardiac troponin T (hs-cTnT) may be associated with dementia. However, limited data exist on their association with either pre-dementia stages, that is, cognitive impairment no dementia (CIND), or the burden of cerebrovascular diseases (CeVD). We therefore, examined the association of these biomarkers of cardiac dysfunction with CeVD in both CIND and dementia. A case–control study, with cases recruited from memory clinics and controls from memory clinics and community. All subjects underwent collection of blood samples, neuropsychological assessment, and neuroimaging. Subjects were classified as CIND and dementia based on clinical criteria whilst significant CeVD was defined as the presence of cortical infarcts and/or more than 2 lacunes and/or confluent white matter lesions in two regions of brain on Age-Related White Matter Changes Scale. We included a total of 35 controls (mean age: 65.9 years), 78 CIND (mean age: 70.2 years) and 80 cases with dementia (mean age: 75.6 years). Plasma concentrations of hs-cTnT were associated significantly with CeVD in both CIND (odds ratios [OR]: 9.05; 95% confidence interval [CI]: 1.64–49.79) and dementia (OR: 16.89; 95%CI: 2.02–142.67). In addition, NTpro-BNP was associated with dementia with CeVD (OR: 7.74; 95%CI: 1.23–48.58). These associations were independent of other vascular risk factors. In this study, we showed that plasma NTproBNP and hs-cTnT are associated with dementia and CIND, only when accompanied by presence of CeVD
