Ride-hailing drivers’ working conditions and social protection in China

ABSTRACT This article aims to examine ride-hailing drivers’ working conditions and social protection in China. Through interviews with 25 ride-hailing drivers in Beijing, we found that their working conditions are precarious, stressful, surveilled, and their social protection exhibits features of inadequacy and fragmentation. They are excluded from social insurance for urban employees due to the lack of a formal employment relationship. Instead, they largely participate in the medical insurance for residents, but its insurance benefits are much lower than those for urban employees. Furthermore, citizens’ participation in residents’ medical insurance is determined by their hukou (i.e. household registration) residency. Internal migrant drivers are only entitled to be insured at their origin where their hukou is located. Despite working in the same occupation and living in the same city, internal migrant drivers and Beijing-native drivers have distinct social insurance benefits. Thus, we propose the binary classification of de jure/de facto residency, which contributes to a deeper understanding of social protection for non-standard forms of employment.

Food-Borne Biotoxin Neutralization in Vivo by Nanobodies: Current Status and Prospects.

Food-borne biotoxins from microbes, plants, or animals contaminate unclean, spoiled, and rotten foods, posing significant health risks. Neutralizing such toxins is vital for human health, especially after food poisoning. Nanobodies (Nbs), a type of single-domain antibodies derived from the genetic cloning of a variable domain of heavy chain antibodies (VHHs) in camels, offer unique advantages in toxin neutralization. Their small size, high stability, and precise binding enable effective neutralization. The use of Nbs in neutralizing food-borne biotoxins offers numerous benefits, and their genetic malleability allows tailored optimization for diverse toxins. As nanotechnology continues to evolve and improve, Nbs are poised to become increasingly efficient and safer tools for toxin neutralization, playing a pivotal role in safeguarding human health and environmental safety. This review not only highlights the efficacy of these agents in neutralizing toxins but also proposes innovative solutions to address their current challenges. It lays a solid foundation for their further development in this crucial field and propels their commercial application, thereby contributing significantly to advancements in this domain.

Remediate and sense: alginate beads empowered by portable electrochemical strips for copper ion removal and detection at environmental sites.

The contamination of environmental sites due to the presence of persistent species represents an important issue to be tackled. In particular, the presence of high levels of metals in soil and surface water is more frequent. One of the metals that sometimes exceeds the permissible limit set by regulatory authorities is copper. For instance, copper-based fungicides are widely used in viticulture. However, copper ions remain in soil and can enter the food chain, posing threats to human health and environmental safety. Although the rapid detection of copper ions using portable sensors is effective in enhancing early warning, it sometimes solves only half of the problem as remediation is not considered. In this paper, we present a novel integrated/portable approach that merges the remediation and sensing of metals by proposing a remediate-and-sense concept. In order to realize this concept, alginate beads were coupled with printed electrochemical strips for on-site copper detection. Within the same architecture, alginate beads were used to remove copper ions from the soil, and printed electrochemical strips were used to evaluate the efficacy of remediation at the point of need. The concept was applied towards soil containing copper ions at the parts per billion level; with few alginate beads and in the absence of additional species, copper ions were quantitatively removed from the matrix; and 3D printing allowed us to combine the printed strips and spheres within a unique tool. The architecture was optimized and the results were compared to inductively coupled plasma-mass spectrometry (ICP-MS) measurements with a recovery percentage of 90%-110%. It should be noted that this novel portable approach may be applied to other pollutants, opening new possibilities for integrated remediation and sensing.

Support needs for return to work among self-employed workers: A focus group study.

The aim of this study is to gain insight into the facilitators, barriers, and support needs of Dutch self-employed workers when returning to work (RTW) after sick leave. Three focus groups were conducted, involving 15 Dutch self-employed workers who were on sick leave due to health problems. The transcripts were analysed through thematic content analysis. Five main themes regarding barriers, facilitators and needs of self-employed workers to RTW were identified: autonomy, social support, client management, financial security and information on sick leave. Having autonomy was considered a facilitator for RTW. However, the participants expressed a need for more financial support, additional guidance from occupational health professionals, and tailored information regarding RTW. The results of this study emphasize a need for optimizing national policy and support for self-employed workers regarding sick leave and RTW.

Work-related musculoskeletal complaints: risk factors and impact on work productivity among university administrative employees

BackgroundWork-related musculoskeletal disorders (WMSDs) are a significant workplace problem leading to loss of productivity and disability. Administrative workers perform computer-based tasks for long periods. Consequently, they are at risk of developing musculoskeletal disorders. The objective of this study was to explore the frequency and risk factors of work-related musculoskeletal complaints and their impact on work productivity among administrative employees of Suez Canal University, Egypt.MethodsThis cross-sectional study was conducted on 300 administrative employees through simple random sampling. Data were collected by an interview questionnaire including sociodemographic, work-related data, ergonomic and psychological risk factors, the Nordic Musculoskeletal Questionnaire (NMQ), and the World Health Organization Health and Work Performance Questionnaire (HPQ).ResultsThe frequency of work-related musculoskeletal complaints in at least one anatomical region over the past year was 74.7%. Neck (47.1%), lower back (40.7%), and shoulder (36.3%) were the most reported sites of complaints. Risk factors significantly associated with work-related musculoskeletal complaints were gender, age, physical activity, work experience, workplace stress, sustained body position, awkward posture, and inadequate rest breaks. Logistic regression revealed that older age (OR = 1.039, p = 0.023), being female (OR = 2.175, p = 0.011), and not having adequate rest breaks (OR = 1.979, p = 0.019) were significant predictors for the occurrence of WMSDs. The risk factors of absenteeism include gender, age, marital status, educational level, physical activity, BMI, work experience, and musculoskeletal complaints.ConclusionMusculoskeletal problems were highly prevalent among administrative employees. Being female and not having adequate rest breaks were significant predictors for the occurrence of WMSDs. Ergonomic interventions and improvement of working conditions are recommended to reduce WMSDs.

Spinel Nanostructures for the Hydrogenation of CO2 to Methanol and Hydrocarbon Chemicals.

Composite oxides have been widely applied in the hydrogenation of CO/CO2 to methanol or as the component of bifunctional oxide-zeolite for the synthesis of hydrocarbon chemicals. However, it is still challenging to disentangle the stepwise formation mechanism of CH3OH at working conditions and selectively convert CO2 to hydrocarbon chemicals with narrow distribution. Here, we investigate the reaction network of the hydrogenation of CO2 to methanol over a series of spinel oxides (AB2O4), among which the Zn-based nanostructures offer superior performance in methanol synthesis. Through a series of (quasi) in situ spectroscopic characterizations, we evidence that the dissociation of H2 tends to follow a heterolytic pathway and that hydrogenation ability can be regulated by the combination of Zn with Ga or Al. The coordinatively unsaturated metal sites over ZnAl2Ox and ZnGa2Ox originating from oxygen vacancies (OVs) are evidenced to be responsible for the dissociative adsorption and activation of CO2. The evolution of the reaction intermediates, including both carbonaceous and hydrogen species at high temperatures and pressures over the spinel oxides, has been experimentally elaborated at the atomic level. With the integration of a series of zeolites or zeotypes, high selectivities of hydrocarbon chemicals with narrow distributions can be directly produced from CO2 and H2, offering a promising route for CO2 utilization.

Impact of COVID-19 on Profession and Health of Female Sex Workers: Apprehension, Acquiescence, and Resilience.

In Surat city of Gujarat, India, female sex workers (FSW)-based targeted interventions (TI) and community-based organizations (CBO) have been functioning since 1998. To document the impact of the COVID-19 lockdown (March-May 2020) on FSWs and STI/RTI/HIV preventive measures provided through TI/CBOs in Surat city, sequential, explanatory mixed-methods design was used. We conducted a desk review of quarterly programmatic data (2018-2020) of four TIs and CBOs and interviewed of 221 FSWs to study pre- and post-lockdown socioeconomic conditions, engagement in sex work, health services during COVID-19 lockdown and coping strategies, followed by five focus group discussions of FSWs and TI/CBO project staff. Study identified four major themes: reasons for working as a FSW during COVID-19 lockdown, entry to sex work during or as a consequence of lockdown, exploitation of FSWs during lockdown, and challenges of TI and CBOs in service provision in pandemic situation. Number of new registrations and STI/RTI detection increased immediately after lockdown. TI/CBO and other NGOs working for women welfare must build financial independence by training them in microeconomics, savings, and entrepreneurship. TI/CBO staff must also include experts in finance or business, trained in emergency response. The presence of strong TI/CBO network facilitated prompt delivery of essential commodities and financial aid to FSWs. However, laboratory and screening services were hampered, which warrants need of introducing self-test kits. In backdrop of decrease in condom distribution, continuation of sex work during lockdown and disruption of routine HIV/STI/RTI screening facilities, our study also recommends intensified HIV/STI/RTI screening among FSWs.

Exploring interactivity effects on learners’ sense of agency, cognitive load, and learning outcomes in immersive virtual reality: A mixed methods study

This study explored the effects of IVR interactivity on learners’ sense of agency, cognitive load, and learning outcomes. The research questions were: 1. “How does interactivity influence the learners’ sense of agency?” and 2. “How does interactivity influence the learners’ cognitive load and learning outcomes?” A mixed-methods experimental design was applied. Safety training interventions, including individually performed IVR scenarios, were held for 68 participants in groups of two to four persons in two work organizations. Single- and repeated-measure questionnaires were the main source of the quantitative data. Qualitative data collection by video recordings and stimulated recall interviews was carried out on 23 persons in total. The results indicate that high interactivity enables a stronger sense of agency for the learners and yields learning benefits by supporting generative cognitive processing. Based on the results, interactivity and learner involvement may be particularly important for achieving affective training goals. Considering the sociocultural and individual factors in training design and pre-briefing the learners are also recommended.

Equipment design and parameters recommendation of rubber modified 3D printed asphalt in pavement maintenance

As an advanced technology for pavement crack maintenance with high automation level, high precision and high efficiency, 3D asphalt printing technology can effectively improve worker safety and ensure the stability of maintenance quality. In order to optimize the printing parameters of rubber modified 3D printed asphalt (R-3DPA), a three-axis asphalt 3D printer was developed in this study through the design and selection of each component, and it was used for the 3D printing of R-3DPA strips, layers, and structures. Based on the comparison of continuity, uniformity, and width of R-3DPA strips, the recommended extrusion nozzle diameter, printing temperature, and printing speed parameter combinations were superiorly selected. According to the analysis of filling degree, width error and thickness of R-3DPA layers, the optimal printing strip width was recommended. Through the evaluation of integrity, surface characteristics and accuracy of R-3DPA structures, the suitable printing layer thickness was determined. The test results showed that the three-axis asphalt 3D printer can be used to measure the parameters of R-3DPA, and the printing accuracy and scale meet the requirements. The recommended parameters for R-3DPA are an extrusion nozzle diameter of 2 mm, a printing temperature of 180 °C, a printing speed of 20 mm/s, a printing strip width of 2.25 mm and a printing layer thickness of 0.4 mm, resulting in structures with good integrity and precision.

Work-related injury or work-related pain? A qualitative investigation of work-related pain and injury management among rehabilitation professionals1.

Patient mobility tasks place rehabilitation professionals (Physical and Occupational Therapists) working in hospitals at high risk for work-related musculoskeletal disorders (WMSDs). However, when investigating engagement with a Safe Patient Handling and Mobility program (SPHM), administrative records at a level one trauma hospital showed that rehabilitation professionals reported zero work-related injuries over an eight-year period. As part of a qualitative study conducted to discover their unique work experiences, we explored some of the reasons that rehabilitation professionals might not report work-related injuries to their employers. Using a collective case study design, six focus groups were conducted with 25 members of the rehabilitation team within a level-one trauma hospital. Focus groups were recorded; transcripts were analyzed for emergent themes using first and second cycle coding procedures. Participants in this study denied experiencing work-related injuries but frequently described working in pain, often attributed to patient mobility tasks. These experiences were not reported to employers. Self-management of their pain through co-worker treatment, over-the-counter medications, or informal alteration in job tasks were reported as common. Administrative injury records may underrepresent injuries among rehabilitation professionals. This may be due to their perception of work-related pain as something different than work-related injuries, or that many of these rehabilitation professionals treat their own work-related pain and symptoms rather than report them. To get a more accurate assessment of injury frequency among rehabilitation professionals, researchers should gather information directly from the participants, and should inquire about work-related pain in addition to injury.

Low back pain, work overload, and associated factors among hospital caregivers.

Caregivers assist patients in treatment based on their care needs and living activities. Very few studies have been conducted specifically on the occupational health and safety of hospital caregivers. This study aimed to investigate the prevalence of excessive workload and low back pain among hospital caregivers and to identify potential associated factors. This cross-sectional study included caregivers working at Gazi University Hospital. Socio-demographic and working-life characteristics were assessed. The Role Overload Scale was used to determine excessive workload and the Roland-Morris Disability Questionnaire was used to evaluate low back pain. The study included 528 participants. A total of 18.7% had work accidents in their department. 49.0% had sharp injuries. 68.9% of the participants performed tasks such as positioning, turning, lifting, or helping patients to walk. 72.2% stood for a long time during the workday. 52.8% thought that they worked under stress. 57.6% had low back pain in the last year and 38.6% in the last month, Significant differences exist in low back pain according to gender, body-mass index, standing for a long time and working under stress. Those who worked at night, had a work accident, positioned patients, stood for a long time, and worked under stress had higher mean scores on the Role Overload Scale. Tools should be used to lift and transport patients. In addition to occupational health and safety training, awareness of musculoskeletal risks should be increased. Employee well-being can be improved through exercise and stress reduction techniques.

A pipeline corrosion detecting method using percussion and residual neural network

Corrosion of pipeline walls can lead to serious safety accidents such as leaks, fires and even explosions. This paper proposes a corrosion detection method using deep learning based on percussion sound for pipelines. The percussion induced acoustic signals are processed by wavelet threshold noise reduction and double threshold endpoint detection to generate the Mel spectrograms, and then an 18-layer residual network (ResNet18) is used to mine the depth information and classify the degree of pipeline corrosion. We conducted experiments to verify the validity of the approach. Seven working conditions are generated by electrochemical corrosion of a pipe specimen, and percussions are applied at five different positions under the same working conditions to collect the impact acoustic signals. The test results show that the method can quickly, efficiently and accurately detect the degree of pipeline corrosion, classify the degree of pipe corrosion without being affected by the striking position Therefore, the model has great potential for application in detecting the internal corrosion of pipelines based on percussion sounds.

Planning Policies and Public Health in Kurdistan Region of Iraq (KRI) and Its Policies to Combat COVID-19 in Duhok City

Purpose: The Kurdistan region of Iraq had been affect by the covid pandemic like the rest of the part in the world and Duhok city specifically faced several problems as the city and health policy were not ready to ace the crises. It had a negative impact on the sustainability of health sector specifically the economic side. This study tries to identify the problems to achieve tan appropriate standard of good health among Kurdistan's general population, especially in the city of Duhok, to ensure more equitable access to health services throughout the country's social and geographic expansion, take into account poverty and to strive to get better treatment, understand the condition of the city of Duhok via COVID-19, and how the government deals with the medical system in this condition, protect and encourage the right to health care for individuals and create equality in the health care system for both genders, beliefs and positions. Methodology: Through conducting the qualitative research approach by using two types for collecting data ( Data Collection Methods) which are primary data and secondary data, primary data for collecting direct information from patients and IDPs and refugees to know their health conditions and whether they are satisfied or not for public health system, physicians as well to know their treatment to patients, and secondary data to gather information from health directorate in Duhok city, camp health administration and humanitarian health organizations to understand better the situation. Findings: The findings of the study indicates that the pandemic struck at a time when public faith in the government was low, the economy was damaged by lower oil sales income, protests were common across the country, and violent extremist acts were on the rise. COVID-19 has worsened long-standing and sometimes deep-seated political, economic, social, and security issues. The COVID-19 pandemic has resulted in a dramatic loss of human life around the world, posing an unprecedented challenge to public health, food systems, and the workplace. The pandemic's economic and social impact is devastating: tens of millions of people are at risk of falling into extreme poverty, while the number of undernourished people is currently estimated to be nearly 690 million, By the end of the year, the number could have risen to 132 million. Unique Contribution to Theory, Practice and Policy: Food security, public health, and employment and labor issues, particularly worker health and safety, all intersect during the COVID-19 crisis. However, in Azadi hospital we cannot talk to people because of virus, the risk of contracting COVID-19 via an infected person's feces appears to be low. The COVID-19 virus may cause intestinal infection and be found in feces, according to some data.

Enhancing Workplace Safety through Personalized Environmental Risk Assessment: An AI-Driven Approach in Industry 5.0

This paper describes an integrated monitoring system designed for individualized environmental risk assessment and management in the workplace. The system incorporates monitoring devices that measure dust, noise, ultraviolet radiation, illuminance, temperature, humidity, and flammable gases. Comprising monitoring devices, a server-based web application for employers, and a mobile application for workers, the system integrates the registration of workers’ health histories, such as common diseases and symptoms related to the monitored agents, and a web-based recommendation system. The recommendation system application uses classifiers to decide the risk/no risk per sensor and crosses this information with fixed rules to define recommendations. The system generates actionable alerts for companies to improve decision-making regarding professional activities and long-term safety planning by analyzing health information through fixed rules and exposure data through machine learning algorithms. As the system must handle sensitive data, data privacy is addressed in communication and data storage. The study provides test results that evaluate the performance of different machine learning models in building an effective recommendation system. Since it was not possible to find public datasets with all the sensor data needed to train artificial intelligence models, it was necessary to build a data generator for this work. By proposing an approach that focuses on individualized environmental risk assessment and management, considering workers’ health histories, this work is expected to contribute to enhancing occupational safety through computational technologies in the Industry 5.0 approach.

Reducing musculoskeletal disorders in iron ore mine operators: A fuzzy-based intervention approach.

This study focuses on evaluating the exposure to whole-body vibration (WBV) and association of musculoskeletal disorders (MSDs) with various risk factors among dumper operators in the mining industry. Despite the issue's significance, prior research has been limited. The study introduces a novel fuzzy-based approach for identifying, selecting, and prioritizing safety measures to mitigate MSD risks. Data collection comprised face-to-face interviews, anthropometric measurements, Rapid Upper Limb Assessment (RULA) scoring for posture assessment, and the Nordic Musculoskeletal questionnaire for assessment of MSD prevalence. Multiple linear and logistic regression models were used to analyse the contributing risk factors to MSDs and WBV exposure. These risk factors formed the basis for a practical approach to select appropriate safety measures based on fuzzy based aggregation method of expert's judgment aimed at mitigating the risk of MSDs. The results revealed that the risk factors such as poor work posture, WBV exposure and poor seat design were significantly associated with neck (adjusted odds ratio aOR = 4.81), upper limb and shoulder (aOR = 3.28), upper back (aOR = 5.09), and lower back pain (aOR = 3.67) at p < 0.05. Using these factors to formulate safety measures to reduce MSD risk, the minimization of sharp turns and abrupt changes in elevation in designing the haul roads, scheduled maintenance practices, and ergonomic seat design were found as important safety measures in this study. Our unique methodological approach in occupational health research could be highly beneficial for tailoring safety measures at the unit level with minimal effort.
