Knowledge, Attitudes and Practices Relating to HIV among Motorbike Taxi Drivers in Parakou, Benin, in 2021

Background and Objective: HIV infection is a major global Public Health threat worldwide, particularly in Sub-Saharan Africa of which Benin. The level of knowledge determines the attitudes and behaviors of the populations towards this infection. The study objective was to assess knowledge, attitudes and practices related to HIV infection among motorbike taxi drivers (MTD) in Parakou in 2021. Methods: This was a descriptive cross-sectional study targeting MTD in Parakou in 2021. Participants were selected by cluster sampling. Pretested Digitized questionnaire using KoboCollect@ applicationserved as a data collection tool. Knowledge, attitudes and practices variable were treated on a score scale. A knowledge score was considered to reflect a good knowledge of HIV if at least two-thirds of the knowledge statements had been correctly answered provided the subject recognized the sexual route as one of modes of HIV transmission, identified at least one preventive measure and meant the incurability of the disease. Quantitative and qualitative variables were appropriately described using the EPI Info 7.1.3.3 software. The participant was classified at positive attitude/practice for HIV prevention, when it has a score of at least 80% and suggests a good preventive measure face a risk of exposure to HIV. Results: A total of 374 subjects were recruited into the study. The mean age was 31.51 ± 7.76 years. Most participants (86.06%) had good knowledge of condom use as an HIV prevention method. The sources of information mentioned were mainly the media (77.07%), relatives or friends (63.38%), and field-workers from non-governmental organizations (37.26%). Routine HIV testing was 50.53%. Among participants, 76.10% reported at least two different sexual partners. Condom use was 59.18 % during the casual sexual intercourse. Within the client-provider relationship with female sex workers, 33.17% had had sexual intercourse with them. The sexual route was the most cited (92.99%), and 90.23% stated that HIV infection can be stabilized by medication in a health structure. Conclusion: The level of knowledge of motorbike taxi drivers in Parakou does not match their behavior with regard to HIV prevention. Appropriate strategies are needed to develop prevention skills in this population. To effectively comb at HIV, it will be necessary to strengthen the targeted HIV preventive interventions at key and bridge populations including motorbike taxi drivers in Benin.

Understanding taxi driver's cruising behavior with ZIP model

The taxi drivers' cruising pattern was learned using GPS trajectory data collected in Shenzhen,China.By employing zero-inflated Poisson model,the impacts of land use and previous pick-up experience on cruising decision were measured.The cruising strategies of different types of drivers as well as the top one driver were examined.The results indicate that both land use and previous pick-up experience affect travel behavior with the former's influence(7.07×10-4 measured by one of the coefficients in zero-inflated Poisson model) being greater than the latter's(4.58×10-5) in general,but the comparison also varies across the types of drivers.Besides,taxi drivers' day-to-day learning feature is also proved by the results.According to comparison of the cruising behavior of the most efficient and inefficient driver,an efficient cruising strategy was proposed,that is,obeying the distribution of land use in choice of cruising area,while learning from pick-up experience in selection of detailed cruising location.By learning taxi drivers' cruising pattern,the development of measures of regulating travel behaviors is facilitated,important factor for traffic organization and planning is identified,and an efficient cruising strategy for taxi drivers is provided.

Moroccan Taxi Drivers Fatigue Using Pichot Questionnaire： A Cross-Sectional Survey

Studies conducted in many countries the world has shown that fatigued driving contributes to approximately 3%-30% of road accidents. We conducted this study to estimate the prevalence of fatigue among taxi drivers and to assess the determinant of fatigue among taxi drivers. In this cross-sectional study, 300 urban and rural taxi drivers from Fez, Morocco were enrolled from January to May 2013. The mean score of Pichot scale was 13.59 ± 8.23. The mean duration of sleep was 6.78 ±1.47 h per day. The mean rate of accident was 2.78 ± 1.12 per year. At the final model of the multiple linear regression we found an association statistically significant between Pichot scale and income, cardiovascular disorders, tobacco use, problems with colleagues, regularity of sleep and sleeping at the wheel. This study opened the door to many discussions about the professional drivers＇ conditions of work and we can argue that we should ameliorate the professional drivers conditions of work in Morocco.

Evaluation of Physical and Mental Quality of Life of Motorcycle Taxi Drivers

Motorcycle taxi drivers are workers who use motorcycle to carry passengers. Objectives: to identify the sociodemographic profile and evaluate the physical and mental quality of life of motorcycle taxi drivers. Methods: Cross-sectional study, held in Campo Grande, Mato Grosso do Sul-Brazil, from May to July 2015 with 301 participants. To calculate the sample size, the margin of error was 5%, confidence level, 95%;and the drivers were randomly selected. For data collection, two instruments were used: the demographic questionnaire and the SF-36 Health Status Questionnaire. Results: Among the 301 respondents, predominance fell on males (98.7%, n = 297), married or in a stable relationship (63.5%, n = 191), with completed high school education (44.9%, n = 135). More than half felt discomfort while working (52.8%, n = 159). Of those with diagnosed disease the predominant type of disease was hypertension (55.5%, n = 30). When male and female were compared, men had lower average in the mental health aspect (63.39 ± 13.22);and women, in the emotional aspect (41.66 ± 31.91). There were significant differences in the scores of physical functioning (p = 0.002), bodily pain (0.043) and general health perceptions (p = 0.003) of the drivers reporting disease, compared to those who did not reported it. Conclusion: The studied motorcycle taxi drivers are mostly male, married, with high school education. Regarding quality of life, men had lower perception in the general mental health aspect whereas women showed lower perception in the emotional aspects. The individuals with disease had lower perceived quality of life in the physical functioning, bodily pain and general health concepts.

Moroccan Taxi Drivers Sleepiness Using Epworth Scale： A Cross-sectional Survey

Many international studies found that fatigue can be a probable major cause of truck driver accidents. The primary goal of the current study was to assess the relation between sleep disorders and accidents by using Epworth sleepiness scale. In this cross-sectional study, 300 urban and rural taxi drivers from Fez, Morocco were enrolled from January to May 2013. All participants were male and their mean age was 42.51 ± 10.81 （range 18-74） years. Their experience in driving was 8.34± 3.56 years on average; which had no significant relationship with their crash history and was not found a confounding factor in this series. The mean duration of sleep was 6.78± 1.47 h per day. The mean rate of accident was 2.78 ± 1.12 per year. The mean Epworth index was 13.23 ± 5.59. The simple linear regression showed a significant correlation between the Epworth sleepiness scale and education （P = 0.030）, age （P = 0.017）, marital status （P = 0.011）, coffee consumption （P = 0.006）, and water pipe （chicha） use （P = 0.01 ）, but there was no significant correlation with history of crash in past years. The multivariate analysis （multiple linear regressions） found a significant association between Epworth scale and age （P = 0.024）, coffee consumption （P = 0.023） and water pipe use （P = 0.027）. In Morocco where road accidents are very frequent and number of serious injuries and death is very high. This is considered as one of the major public health problems and hence public health officials, legislators and the police should collaborate in multidisciplinary approach to have effective preventives measures. This study can be the start of many debates about the most efficient preventive measure to ameliorate professional drivers＇ work condition and to reduce road accident and hence save thousands of lives from the ＂traffic war＂ in Morocco.

Bronchospasm Diagnosis in Motorcycle Taxi Drivers Exposed to Automotive Pollutants in Porto-Novo

Background: In African cities, chronic exposure to pollutants is the most common public health problem faced daily by motorcycle taxi drivers. In Benin, studies conducted on motorcycle drivers, have shown the presence of nitrogen oxides, carbon monoxide, sulfur dioxide, volatile organic compounds and particulate matter in ambient air, which may affect lung function. Aims: This study aims to diagnose potential respiratory problems among 48 motorcycle taxi drivers (47.02 ± 8.75 years) compared to a control group made up of 52 people (46.38 ± 8.81 years) in Porto-Novo, Benin. Methods: A questionnaire, two exploration pulmonary function tests and two 6-minute walk tests were used to identify symptoms and changes in respiratory variables that reveal the existence of bronchospasm. Results: The frequency of respiratory symptoms noted among motorcycle taxi drivers is higher than that recorded among members of the control group. We observed that motorcycle drivers at rest and after physical effort have significantly lower respiratory variables (FVC, FEV1, PEF, FEF25-75, FEF50 and FEF25) (p < 0.05) than those recoded in control group. Conclusion: It can therefore be concluded that, because of the relatively long duration of exposure among motorcycle taxi drivers, the inhalation of automobile pollutants, may cause respiratory problems in this population.

Higher Plasma Potassium Level Reduces 10-Year Cardiovascular Disease Risk Predicted by the Framingham Risk Score among Taxi-Motorbike Drivers Residing and Working in Cotonou, Benin

Hypertension, obesity, smoking, dyslipidemia, and type 2 diabetes (T2D) are the major risk factors for developing cardiovascular diseases (CVD). Recent studies revealed that taxi-motorbike drivers (TMDs) in Cotonou had higher rates of CVD risk factors, but their impacts on cardiovascular events have rarely been studied. The Framingham risk score (FRS) is an algorithm that considers CVD risk factors and estimates the risk of developing CVD in the next 10 years. Our objectives were to assess the 10-year CVD risk predicted by the FRS, and to examine the relationships of 10-year CVD risk with plasma iron and potassium levels among TMDs. We included 134 TMDs (22 - 59 years old) who had no prior diagnosis of CVD or T2D, and not taking medications affecting iron and potassium homeostasis. Conventional cardiovascular risk factors were used to calculate the 10-year CVD risk, which was categorized as low (20%). FRS > 2%, which corresponded to the 75th percentile of FRS distribution in our study population, was used as a cut-off value to classify participants into two groups. Plasma iron and potassium levels were segregated into tertiles and their associations with 10-year CVD risk were quantified by multivariate-adjusted logistic regression to calculate the odd ratios (ORs) to being above the 75th percentile of 10-year CVD risk with the corresponding 95% confidence intervals (CIs). We found that 62.0% of participants had at least one of cardiovascular risk factors. Approximately 97.8% of TMDs had 10-year CVD risk 4.8 mmol/L led to an 83% risk reduction of having 10-year CVD risk > 2% (OR = 0.17, 95% CI: 0.04 - 0.82, P = 0.027). In conclusion, our findings showed that high plasma potassium levels associate with reduced 10-year CVD risk among TMDs. Interventions focused on monitoring of plasma potassium, particularly in those with existing cardiovascular risk factors, may help prevent CVD.

Investigating the trip configured causal effect of distracted driving on aggressive driving behavior for e-hailing taxi drivers

Risky driving behavior of taxi drivers typically evaluated for full operation or sometimes sorted into occupied and empty running trips.In this paper,we simultaneously analyze aggressive driving and distracted driving of taxi drivers under three different trip categories.Trip origin is considered a transition from without ride-order to with ride-order travelling or from with ride-order to occupied travelling,and a destination as a transition from occupied to without ride-order travelling and vice versa.Distracted driving is characterized by driver interference,driver mobile use and some entertainment aspects,while specific harmful and risky actions are considered for aggressive driving.High-resolution and real-time kinematic parameters of taxis were recorded by the in-vehicle recorder VBOX for overall 562 trips.The distracted driving parameters and aggressive driving actions were monitored through python data collector web application that was specially programmed for this particular research.Besides dual dash cam(i.e.,front and inside car camera),drivers’ whole day driving history from their Chinese ride-hailing Di Di smart application was used to differentiate occupied trips,unoccupied trips with ride-order and unoccupied trips without ride-order.Structural equation modeling(SEM) is practiced in this paper to understand the influence of distracted driving indicators on aggressive driving behaviors.The multi-group model analysis of SEM indicated that handling distracted risky driving could control aggressive driving behavior up to 96% and 98% inunoccupied without ride-order trips and unoccupied trips with ride-order respectively.The model has also identified the sensitive risky driving indicators for each group separately.

High-Level Circulating Total Calcium and Low Phosphate as Predictors of Insulin Resistance among Non-Diabetic Taxi-Motorbike Drivers Living and Working in Cotonou, Benin

Insulin resistance (IR) is a well-recognized marker of increased cardiovascular diseases (CVDs) and type 2 diabetes (T2D) risk. Therefore, screening for IR predictors would help reduce the likelihood of progression from early stage of IR to T2D or CVDs. However, the knowledge of association between IR and circulating total calcium (CTCa) and phosphate levels among non-diabetic patients in Benin is lacking. We investigated whether CTCa and phosphate levels within the normal ranges are associated with IR risk among taxi-motorbike drivers (TMDs) living and working in Cotonou. We evaluated 134 non-diabetic TMDs (aged 22 - 59 years) based on CTCa, phosphate, glucose, fasting insulin, and IR levels. IR was assessed using the homeostatic model assessment-insulin resistance (HOMA-IR). IR was defined as the 75th percentile of HOMA-IR value. Cardiometabolic factors were analyzed by tertiles of CTCa and phosphate levels (low, middle, and high groups). Logistic regression models evaluated the relationships between IR and CTCa and phosphate levels. Our results showed that participants with high CTCa levels had the highest prevalence of IR, elevated total cholesterol and high-density lipoprotein cholesterol. In a fully adjusted model, the odd ratio (OR) of having IR comparing the highest (>2.50 mmol/L) to the lowest CTCa levels (1.23 mmol/L) and the lowest levels (<1.10 mmol/L) of phosphate was 0.28 (p = 0.037). In conclusion, our study demonstrates that elevated CTCa and low phosphate levels are significant predictors of IR in non-diabetic patients. Continuous monitoring of these markers may help identify earlier individuals at greatest IR risk.

Elevated White Blood Cell Count Is Associated with an Increased Risk of Insulin Resistance among Non-Diabetic Taxi-Motorbike Drivers Working in Cotonou, Benin

High white blood cell count (WBC) and insulin resistance (IR) are interrelated events that contribute to non-communicable diseases (NCDs), including type-2 diabetes (T2D). However, associations between IR and hematological parameters have never been explored in populations of Benin. The aims of this study were to determine the prevalence of IR and associated hematological parameters in taxi-motorbike drivers (TMDs) working in Cotonou. A total of 133 participants were analyzed in this cross-sectional study. Complete blood count, including WBC and platelet, as well as fasting plasma glucose and insulin, were performed by standard procedures. IR was assessed using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Factors associated with IR, their odds ratios (ORs) and 95% confidence intervals (CIs) were determined by logistic regression analysis. The mean age of the study participants was 39.3 years. The HOMA-IR cut-off (75th percentile) for IR was 5.9. The overall prevalence of IR was 24.1%. IR increased with the increase of exposure duration and WBC levels. Logistic regression analysis revealed that the risk of IR increased significantly with higher total WBC, with adjusted ORs (95% CI) for the second and third tertiles of 3.56 (1.10 - 11.58) and 4.01 (1.21 - 13.31), respectively. Similar patterns of associations were observed in an analysis restricted to non-drinkers, although these estimates lacked statistical significance. BMI > 24.2 kg/m2 was independently associated with an increased risk of IR (OR = 3.82, 95% CI: 1.33 - 11.03, P = 0.013). In conclusion, the prevalence of IR in TMDs was 24.1%. IR was significantly associated with elevated WBC count and BMI. WBC may serve as a biomarker to identify individuals at the greatest IR risk.

Low Plasma Potassium and High Iron Levels Increased the Risk of Dyslipidemia among Non-Diabetic Taxi-Motorbike Drivers Living and Working in Cotonou, Benin

Non-traditional cardiovascular risk factors such as iron and potassium may play a role in lipid metabolism. However, information on this association is lacking in populations of Benin. This study evaluated the associations between plasma iron and potassium levels and risk of dyslipidemia among taxi-motorbike drivers (TMDs) in Cotonou. We conducted a cross-sectional study on 134 males TMDs aged ≥20 years old, of whom 39 (29.1%) had dyslipidemia. Plasma biochemistry including measurements of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), iron, and potassium were performed. Dyslipidemia was defined as any or combinations of the following: TC > 5.2 mmol/L, LDL-C > 3.4 mmol/L, TG > 1.7 mmol/L, and HDL-C 18.8 μmol/L) to the 1st tertile of plasma iron (<13.6 μmol/L) was 3.85, (95% CI: 1.20 - 12.35, p = 0.023). We observed similar patterns of association in a subgroup analysis restricted to normotensive patients, although the estimates lacked statistical significance. Our findings also revealed that the risk of dyslipidemia decreased when plasma potassium levels increased. The OR (95% CI) for dyslipidemia comparing the 2nd tertile (4.4 - 4.8 μmol/L) to the 1st tertile (<4.3 μmol/L) of potassium was 0.31 (0.11 - 0.86, p = 0.025). Interestingly, the risk of dyslipidemia decreased progressively (81% to 86%) and significantly across plasma potassium tertiles when restricting analysis to normotensive patients. The ORs (95% CI) for dyslipidemia comparing the 2nd and 3rd tertiles to the 1st tertile of plasma potassium were 0.19 (0.04 - 0.87, p = 0.032) and 0.14 (0.02 - 0.93, p = 0.043). In conclusion, our study shows that higher plasma iron and low potassium levels are significant predictors of dyslipidemia in TMDs. As such, the findings have public health implications for predicting and preventing dyslipidemia and associated cardiometabolic diseases. However, longitudinal studies are needed to determine if disturbances in iron and potassium levels, even within the normal range, are precursors or consequences of dyslipidemia.

网约车平台用工的法律逻辑——基于英美等国法院对Uber司机案裁判的研究

网约车司机与平台之间究竟属于哪种类型的劳动用工关系,这在学界和法律实务部门都是至今尚未能形成定论与共识的话题。域外相关国家及其地方政府和司法机关的认识也存有差异,但基本判断似乎越来越接近。即网约车司机属于具有稳定使用关系的“工人”,而不是具有稳定雇佣关系的“雇员”。这种既具备稳定使用关系,又具有相对劳动自由度的新型劳动者,在法律上并没有摆脱用工方对其进行的控制与监督管理,也没有摆脱经济上的从属性,因而应该被纳入劳动法的调整与保护范围。现有工厂制时代形成的劳动法体制,应根据网络用工的特点和要求做相应的调整,以能够覆盖和保护网络从业劳动者的合法权益。

考虑网约车竞争的机场出租车供需均衡博弈模型

为有效解决机场出租车供需不均衡问题,本文基于完全信息下静态非合作博弈理论提出机场出租车司机及乘客两个群体决策的纯策略博弈模型。将网约车竞争影响引入出租车司机群体决策收益函数的构建中,探讨不同竞争强度对出租车司机群体决策结果的影响。同时,考虑排队长度、上客速率、交通状况、交通费用及多交通方式分流等因素研究乘客群体决策的收益函数,反映乘客群体不同决策结果对司机的影响。以北京首都国际机场为案例进行实证分析。结果显示:在北京市网约车行业平均竞争水平下,两群体通过互馈影响达到纳什均衡时,整体供给略高于需求,其中,早晚高峰时段机场出租车呈现供大于求的状态;地铁停运后的凌晨则需求远大于供给。针对当前网约车竞争水平下达到纳什均衡时的机场出租车每日供需不均衡现象,可以适当提高出租车司机对网约车竞争影响的认知。

数字劳动秩序的构建、消解与调节——一项基于传统巡游出租车司机的考察

平台经济蓬勃发展并将彻底颠覆诸多传统行业的规则,传统行业中的常规劳动者群体正处在新旧秩序交替之间的特殊过渡期。通过聚集中国长三角地区超大、特大城市的传统巡游出租车司机群体,以这一群体的媒介化生活为实践田野,借助建构型扎根理论方法阐释这种处于两种经济形态过渡地带的数字劳动秩序何以构建。研究表明,平台通过任务分派、规则指导和绩效评估形成了劳动秩序建构的主导性力量;而司机群体借由选择性接单、技术盗用、平台脱媒和自我脱离,与劳动秩序中的不平等权力关系形成对峙;技术想象与规则认同是司机在平台劳动场景之下存有的积极动因,身份妥协和规则迎合则是他们在平台劳动场景之下维持工作信念的支撑力所在。

出租车高效益行程特征

为提高出租车营运效率和服务水平,以重庆为案例,研究出租车行程特征与出租车驾驶员单位时间收入的关联机理。首先,基于关联的出租车营运数据和轨迹数据构建行程特征指标;其次,构建随机森林预测模型分析行程特征对单位时间收入的相对重要性及显著性;然后,构建多分类Logistic回归模型分析行程特征对单位时间收入的量化影响。研究结果表明:行程特征指标可用于预测驾驶员单位时间收入且准确性较好,送客速度、寻客时长、长单数量对平均单位时间收入预测的相对重要性最大;寻客行程迂回度、送客行程迂回度、寻客里程的增加会显著促使普通效益驾驶员降为低效益驾驶员,而寻客行程迂回度、寻客区域偏好度、寻客里程的减少及送客速度的增加会显著促使普通效益驾驶员上升为高效益驾驶员。高效益驾驶员具有寻客积极主动、不偏好特定区域、倾向预期通行速度快的短路径、有长单偏好但不刻意追求等特征。本文弥补了先前相关研究在行程特征与效益的关联性构建,多样化行程特征对单位时间收入的表征与预测,高效益出租车驾驶员营运特征勾勒等方面的不足;可为城市交通管理、出租车数量管控及运价调整等提供理论依据和技术支撑。
