The Effect of Cash Flow Variation on Project Performance: An Empirical Study from Kuwait
Nawaf Marzouq AL-NASSAFI 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.3
Despite the relationship between cash flow, financial management, and project performance, no study examined the mediating role of financial management on the relationship between cash flow and construction project performance, especially in Kuwait. The goal of this study was to examine the impact of cash flow fluctuations on construction project performance, as well as the role of financial management in mediating this relationship. To accomplish these goals, the researcher employed a descriptive-analytical method to create a questionnaire of 31 items. The study’s sample was chosen at random and includes (181) project managers and firm owners from contractors’ companies in Kuwait. The study found a statistically positive and significant effect of cash flow variation on project performance from the perspective of Kuwaiti contractors at the significance level (0.05), as well as a mediated role of financial management in the relationship between cash flow variation and project performance. The research came up with a number of recommendations based on the findings, including the need for contractors to have a better understanding of cash flow to arrange project activities correctly and efficiently. Further studies may be included into the effect of cash flow forecasting (planning) and financial management (control) on various construction activities.

The study aimed to assess the availability of intellectual capital in Kuwaiti private universities in terms of its three dimensions (human capital, structural capital, and relational capital), as well as its role in crisis management (crisis preparedness, crisis mitigation, confrontation, and response to the crisis, and learning from the crisis) during the COVID-19 pandemic. Members of the boards of trustees, university presidents, their deputies, and deans of the colleges were chosen as respondents to this study from a sample of (8) private universities in Kuwait, with the sampling unit consisting of leaders in these universities. The study revealed that all dimensions of intellectual capital play a statistically significant impact in executing crisis management during the COVID-19 pandemic at Kuwaiti private universities after conducting the data analysis process. The study concluded that universities should pay attention to intellectual capital in all its dimensions (human capital, structural capital, and relational capital) because of its role in improving their ability to implement crisis management strategies and strive to improve their capabilities to face crises by implementing crisis management strategies.

Botanical-based nanosynthesis has been recently reported as a cheap alternative for mosquito management. In this study, we investigated the synthesis of silver nanoparticles (AgNPs) using the leaf extract of Rubus ellipticus and AgNPswere characterized using UV–vis spectroscopy, XRD, FTIR, SEM, TEMand EDX analyses. The toxicity of R. ellipticus leaf extract and AgNPs was evaluated against eggs, larvae and adults of Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. Compared to the leaf aqueous extract, biosynthesized AgNPs showed higher toxicity against the mosquito larvae with LC50 values of 12.50, 13.83 and 15.09 μg/mL, respectively. AgNPs exerted zero hatchability at 60, 75 and 90 μg/mL on A. stephensi, A. aegypti, and C. quinquefasciatus, respectively. Concentrations of 12–60 μg/mL reduced egg laying by gravid females from72.28 to 91.48%.Maximumadulticidal efficacywas observed for AgNPs,with LD50 values were 21.10, 23.04 and 25.06 μg/mL, respectively. AgNPs were found safer to non-target organisms Anisops bouvieri, Diplonychus indicus and Gambusia affinis, with LC50 values ranging from 896 to 2261 μg/mL. Overall, R. ellipticus-fabricated AgNPs acted as effective toxic agents and ovideterrents against three important mosquitoes species, with little harmful effects on non-target aquatic species.

Mosquito-borne diseases represent a major human and animal health problem in all tropical and subtropical countries worldwide. The synthesis of eco-friendly metal nanoparticles is a fast-growing branch of current nanoscience with a number of biomedical and entomological implications. In this study, we investigated the one-pot synthesis of silver nanoparticles (Ag NPs) using a cheap leaf extract of Merremia emarginata (Convolvulaceae). Bio-reduced Ag NPs were characterized by UV–visible spectrophotometry, Fourier transform infrared spectroscopy, X-ray diffraction analysis, atomic force microscopy, scanning electron microscopy and transmission electron microscopy. SEM, TEM and AFM morphological nanocharacterization showed that this synthesis led to the production of size-controlled Ag NPs, ranging from 25 to 65 nm. The acute toxicity of M. emarginata leaf extract and biosynthesized Ag NPs was evaluated against third instar larvae of the malaria vector Anopheles stephensi, the dengue and Zika virus vector Aedes aegypti and the filariasis vector Culex quinquefasciatus. Compared to the leaf aqueous extract, Ag NPs showed higher toxicity against A. stephensi, A. aegypti, and C. quinquefasciatus with LC50 values of 8.36, 9.20 and 10.02 μg/mL, respectively. M. emarginata-fabricated Ag NPs were found safer to non-target aquatic biocontrol agents Anisops bouvieri, Diplonychus indicus and Gambusia affinis, with LC50 ranging from 415.61 to 25,153.46 μg/mL. However, although it has been proven the AgNPs fabricated in the present study are more effective if compared to the crude M. emarginata extract, they still exert some toxicity on biocontrol agents, thus further research is required to produce more eco-friendly formulations for field purposes.

Metal chelation-enhanced changes in surface plasmon resonance (SPR) band of gallic acid-functionalizedAgNP solution to monitor aluminum ions (Al3+) is reported herein. In aqueous solution, Al3+ selectivelyinduced a strong absorbance with large shifts up to125 nm from the SPR band with color changing fromorange to red. This study illustrates that hydroxyl groups of phenol affect the response of a probe thattunes the absorbance maxima to a longer wavelength at 525 nm. Moreover, the rapid formation of aAgNP-Al3+ coordination complex was demonstrated by real-time monitoring, adsorptive removal, andenergy dispersive spectroscopy mapping.
