Ride-Hailing Drivers’ Preference for Fairwork Principles of Trustworthy Labour-Platform Management and Greater Worker-Autonomy and Willingness to Form and Join Worker-Platform Co-Operatives in Kenya

Ride-hailing worker-platform co-operatives had emerged as part of and for at least fairwork principles. Moreover, studies on e-drivers have recommended the formation of worker-platform co-operatives in Kenya. The actual worker-platform co-operatives by e-drivers are yet to be established. It was against this backdrop that a study was conducted to determine the extent of ride-hailing drivers’ preference for fairwork principles of trustworthy labour-platform management, greater worker-autonomy and willingness to form and join worker-platform co-operatives. The study was grounded in the social exchange theory, affective theory of social exchange, and utility theory. The researcher applied critical-realism research philosophy and multimethod research designs of discrete choice experiments and sequential explanatory mixed method research designs. Using the Yamane sampling formula, the study used quantitative data from 497 respondents from sampled 600 of the 20,000 e-drivers in the Nairobi Metropolitan Region. The quantitative data was analysed using multinominal logistic regression. Moreover, the study used qualitative data from 11 participants, analysed using thematic analysis. Results indicated that the two fairwork principles were statistically significant to e-drivers’ willingness to form and join worker-platform co-operatives. The trustworthy platform management (TPM) principle, in particular, was a highly preferred fairwork principle in terms of e-drivers’ willingness to form and join worker-platform co-operative model (Coeff=2.62; SE = 0.400, Z = 6.54, p< .001), compared to the greater worker-autonomy contract (GAC) principle (Coeff=1.565, SE = 0.202, Z = 7.74, p< .001). This study brings practical and theoretical contributions to improve the e-drivers’ benefits from the ride-hailing sector. Policymakers, promoters, and platform workers like e-drivers could understand how best to promote worker-platform co-operatives to succeed in the country’s societal context.

Ride-Hailing Drivers' Preferences for Fairwork Principles of Satisfactory Working Conditions and Fair Pay-Profit Distribution and Willingness to Form and Join Worker-Platform Co-Operatives in Kenya

Ride-hailing drivers (e-drivers) are among the platform workers who successfully embrace the worker-platform co-operative model's emergence to counter capitalistic ride-hailing platforms and their complex ecosystems, which align with fairwork principles of pay, condition, contracts and (platform) management. This study was conducted to determine the extent of ride-hailing drivers' preferences for satisfactory working conditions, fair pay-profit distribution and willingness to form and join worker-platform co-operatives in Kenya. The study was grounded in the social exchange theory, affective theory of social exchange, and utility theory. The researcher applied critical-realism research philosophy and multimethod research designs of discrete choice experiments and sequential explanatory mixed method research designs. Using the Yamane sampling formula, the study used quantitative data from 497 respondents from sampled 600 of the 20,000 e-drivers in the Nairobi Metropolitan Region. The quantitative data was analysed using multinominal logistic regression. Moreover, the study used qualitative data from 11 participants, which was analysed using thematic analysis. Results indicated that the two fairwork principles were statistically significant to e-drivers’ willingness to form and join worker-platform co-operatives. fair pay-profits distribution (FPD) principle, in particular, was a highly preferred fairwork principle in terms of e-drivers’ willingness to form and join the worker-platform co-operative model (Coeff=1.564, SE = 0.234, Z = 6.67, p< .001), compared to the satisfactory working conditions (SWC) principle (Coeff=0.783, SE = 0.156, Z = 5.012, p< .001). This study brings practical and theoretical contributions to improve the e-drivers’ benefits from the ride-hailing sector. Policymakers, promoters, and platform workers like e-drivers could understand how best to promote worker-platform co-operatives to succeed in the country’s societal context.

Rapid and sensitive detection of staphylococcal enterotoxin E using a time-resolved fluorescence immunochromatography assay

Staphylococcal food poisoning is a significant foodborne illness caused by staphylococcal enterotoxins (SEs). Immunoassays have become the primary method for rapidly detecting harmful bacteria and toxins because of their excellent sensitivity and specificity. However, these assays have limitations in that they cannot differentiate between types of SEs and do not provide rapid, on-site, quantitative testing. In this study, a time-resolved fluorescence immunochromatography assay (TRFICA) was developed specifically for detecting staphylococcal enterotoxin E (SEE), which is commonly found in dairy products. Compared with a double antibody sandwich enzyme-linked immunosorbent assay, which had a detection limit of 0.028 ng/mL, TRFICA demonstrated comparable sensitivity, enabling SEE quantification with a detection limit as low as 0.081 ng/mL in infant formula. Validation by spiking infant formula samples confirmed no cross-reactivity with analogs (recoveries ranged from 93.17% to 128.77%). Furthermore, with an 8-min reaction time and interpretation delivered by a portable TRFICA strip reader, our method demonstrates potential for use in mobile and on-site detection. This study describes a rapid, easy, and reliable method for detecting trace levels of SEE in infant formula, which could serve as an early screening tool toward preventing food poisoning in infants and children.

The research was designed as a descriptive and explanatory study to both describe relevant statistical data and explain the causes and effects observed in the study. Data were analyzed using descriptive statistics, including frequencies, percentages, and numerical values, as well as inferential statistics, such as correlation analyses and multiple regression models. University performance was measured through various indicators, including stakeholder engagement and satisfaction, revenue generation from business entities, quality of education, research and community services, the expansion of universities with modern facilities, and the number of academic programs offered. The findings revealed that the causes of academic staff turnover have a positive relationship with university performance, while turnover itself has a negative relationship with university performance. This implies that if universities effectively manage the causes of academic staff turnover, their overall performance is likely to improve.

Experimental and Theoretical Study on Surface Reactivity and CO Generation Mechanism of Bituminous Coal during Room-Temperature Oxidation.

To investigate the evolution of the microscopic chemical structure during the oxidation of bituminous coal at room temperature (25 °C) and infer the formation mechanism of carbon monoxide (CO), a self-designed closed-system coal oxidation experimental setup was employed to measure the CO generation from three bituminous coal samples [Duanwang (DW), Linsheng (LS), and Kunning (KN)]. 13C nuclear magnetic resonance and X-ray photoelectron spectroscopy were used to determine the structures and contents of different carbon atoms and surface elemental compositions and chemical states of the coal samples. Molecular models were constructed on the basis of the experimental data, and reactive force field pyrolysis simulation was used to trace the carbon atoms in the generated CO molecules. In combination with the results of interactive Mantel correlation analysis on the Fourier transform infrared experimental data of coal samples oxidized at room temperature for 0, 12, 24, 36, 48, and 60 h, the main functional groups, structures, and evolution of coal involved in CO formation during normal temperature oxidation were determined. The constructed molecular formulas for the coal samples were C154H122O28N2S for DW, C145H114O16N2S2 for LS, and C155H92O16N2S for KN. The formation of CO was related to the transformation of carbonyl (C═O), phenolic hydroxyl (-OH), ether (C-O-C), aromatic, and aliphatic structures in the coal.

Effect of In Vitro Digestion on Bioactive Peptides Related to Immune and Gut Health in Intact Cow's Milk and Hydrolyzed Protein-Based Infant Formulas.

Background/Objectives: Human milk is the optimal source of nutrition and protection against infection for infants. If breastfeeding is not possible, standard and hydrolyzed infant formulas (IF) are an alternative. Extensively hydrolyzed IFs (eHFs) contain bioactive peptides, but their activities have rarely been evaluated. The aim of this study was to characterize and compare the bioactive peptide profiles of different eHFs and standard IFs before and after in vitro digestion. Methods: Two forms, liquid and powder, of intact protein formula (iPF) and eHF were subjected to in vitro gastrointestinal digestion, mimicking a young infant's gut (age 0-4 months) and an older infant's gut (>6 months). Bioactive peptides of in vitro digested and undigested formulas were analysed with Liquid Chromatography-Mass Spectrometry (LC-MS). Results: In all samples, a variety of peptides with potential bioactive properties were found. Immuno-regulatory peptides, followed by antimicrobial and antioxidative peptides were most frequent, as were peptides promoting wound healing, increasing mucin secretion, regulating cholesterol metabolism, and preventing bacterial infection. Peptides typically found in yoghurt and colostrum were identified in some formula samples. Conclusions: The high amounts of bioactive peptides with various properties in eHFs and iPFs indicate a possible contribution to infection protection, healthy gut microbiomes, and immunological development of infants. eHFs showed similar compositions of bioactive peptides to iPFs, with intermittently increased peptide variety and quantity.
