The use of real-time connected vehicles and HERE data in developing an automated freeway incident detection algorithm

Traffic incidents cause severe problems on roadways. About 6.3 million highway crashes are reported annually only in the United States, among which more than 32,000 are fatal crashes. Reducing the risk of traffic incidents is key to effective traffic incident management (TIM). Quick detection of unexpected traffic incidents on roadways contribute to quick clearance and hence improve safety. Existing techniques for the detection of freeway incidents are not reliable. This study focuses on exploring the potential of emerging connected vehicles (CV) technology in automated freeway incident detection in the mixed traffic environment. The study aims at developing an automated freeway incident detection algorithm that will take advantage of the CV technology in providing fast and reliable incident detection. Lee Roy Selmon Expressway was chosen for this study because of the THEA CV data availability. The findings of the study show that emerging CV technology generates data that are useful for automated freeway incident detection, although the market penetration rate was low (6.46%). The algorithm performance in terms of detection rate (DR) and false alarm rate (FAR) indicated that CV data resulted into 31.71% DR and zero FAR while HERE yielded a 70.95% DR and 9.02% FAR. Based on Pearson’s correlation analysis, the incidents detected by the CV data were found to be similar to the ones detected by the HERE data. The statistical comparison by ANOVA shows that there is a difference in the algorithm’s detection time when using CV data and HERE data. 17.07% of all incidents were detected quicker when using CV data compared to HERE data, while 7.32% were detected quicker when using HERE data compared to CV data

Challenges of Cross Border E-Commerce in TANZANIA: A Case Study of TANZANIA in Comparison with CHINA

Cross Border E-Commerce has gained a huge momentum as far as globalization is concern. Countries like China have been benefited a lot out of it but Tanzania has been lagging behind to towards development of this initiative. This study was done through analyzing major issues that constraint Tanzania in Cross Border E-Commerce and found ways to emancipate those key challenges through checking efforts made by The Government of China. In such case finding ways to recommend those techniques to Tanzania since she has developed a dream called VISION 2025. VISION 2025 established with the aim of making Tanzania to become the middle income country by the end of the year of 2025. The study was done through analyzing studies done by different scholars in relation with what Tanzania is going through. Issues of strengthening Diplomatic ties with China, Infrastructure development, Government support, introduction of One Stop Services/Centers and promotion of local SMEs were suggested

Views and opinions of mass media key informants on coverage of issues related to maternal, newborn and child health in Lake Zone, Tanzania

In Tanzania, the mass media is a primary means of communicating health information to urban and rural populations. While unsafe abortion is the leading cause of maternal deaths and complications in Tanzania, this has increased the high unintended pregnancy rate. Journalists, editors, program managers and producers play a significant role in determining the health-related issues reported. In the present study, the views, and opinions of mass media key informants on coverage of issues related to maternal, newborn and child health in Lake Zone were investigated. This qualitative study was conducted with key informants from 24 mass media outlets that covered the Lake Zone in Tanzania. Twenty-seven key informants from media outlets (radio, television, and newspapers) were recruited to participate in the study. Results revealed that most key informants identified breastfeeding, antenatal care (ANC) visits, facility deliveries and malaria as essential and the MNCH issues covered mainly by mass media. In MNCH issues identified, breastfeeding and ANC visits were more likely to be endorsed as issues covered in the media compared to facility deliveries and malaria. Mass media campaigns were the most effective and popular way of disseminating MNCH-related information

Common Preventable Health and Social Problems Encountered by Elderly in Shinyanga Region in the Northern Part of Tanzania

In Tanzania elders are respected as repositories of inherited wisdom, experienced and principal decision makers in the community. However, evidence shows that such repositories are no longer considered important in most societies. As a result elders are neglected with some mistreatment in terms of provision of health and social services for instance; at times they get denied and ignored of their obvious rights, ignoring their retirement benefits and the rights onto free social services as per the Tanzania National Ageing Policy of 2003. Elders are therefore faced with physical, psychological and geriatric social suffering. It is on this basis that this study tries to explore the common preventable health and social problems encountered by elderly in Shinyanga Region in northern part of Tanzania. Across sectional community based study of 465 subjects randomly selected was done in three wards of Kahama District. The district was selected randomly out of 8 districts of Shinyanga Region, structured questionnaires with both closed and opened endower used; the information was collected from house to house and other information collected from health facilities within the wards as every ward had one public health facility; subjects (respondents) were obtained using purposive sampling technique aiming at elderly with 60 years of age and above. Kahama district has a population of approximately 36,014 of which 1500 (4%) are in the elderly age group of 60 years and above. The study population was 465 which is 30% (465/1500) of the geriatric population of Kahama. Among this group 5% were female while 41% were male and 53% (248/465) were married. 64% (297/465) were taking care of themselves, 32% (150/465) cared by relatives and 4% (18/465) cared by the community. Among the respondents, 40% (185/465) were affected by HIV/AIDs in one way or another either living with orphans whose parents died of HIV/AIDS or asking care of the infected patients within the family. It was also found that 73% of the geriatrics were not exempted from medical treatment fees so they had to pay for their medical care. However, only 32% were aware of getting free treatment and 61% of the study populations were not satisfied with the medical care provided at the public health facilities. The common diseases affecting this age group are: Eye problem 59% (273/465); Arthritis 52% (241/465); Dental problems 27% (124/465); Hypertension 23% (107/465); Backache 22% (105/465); Malaria 28% (132/465); Hearing problems 26% (121/645); Urinary tract Infection 35% (165/465); Depression 8% (36/465). Dementia was also a problem though we had no tools to confirm the diagnosis; some of the geriatrics had more than two diseases. The majority of the elderly age group in Kahama District are not aware of their rights that they deserve free treatment according to Tanzania policy, furthermore for assessment and screening of health problems. A majority of the elderly die prematurely due to preventable diseases and more than half of the diseases affecting geriatrics are preventable

Antenatal depression is associated with pregnancy-related anxiety, partner relations, and wealth in women in Northern Tanzania: a cross-sectional study

Psychosocial health problems, specifically depression during pregnancy, can have negative impact on birth outcomes, postnatal mental health of the mother, and infant health. Antenatal depression is more prevalent among women in low- and middle-income countries than among women in high-income countries. Risk factors for antenatal depression reported in the literature relate to pregnant women in South Asia. Consequently, this study assessed depression in pregnancy and related psychosocial risk factors among select pregnant women residing in Mwanza region, Northern Tanzania. We analysed data from 397 pregnant women recruited from three antenatal clinics for the period June-August 2013 for this cross-sectional study. Women provided data at one time point during their pregnancy by completing the Edinburgh Postnatal Depression Scale and a structured questionnaire assessing psychosocial, demographic, and behavioural risk factors related to antenatal depression. Multiple logistic regression analysis was performed to determine the relationship between risk factors examined and antenatal depression. Overall, 33.8 % (n = 134) of pregnant women had antenatal depression. Pregnancy-related anxiety was associated with antenatal depression (odds ratio (OR) 1.36, 95 % confidence interval (CI) 1.23 to 1.5). Pregnant women with poor relationship with partner and low/moderate socio-economic status had the highest OR for antenatal depression (82.34, 95 % CI 4.47, 1516.60) after adjusting for other covariates. Pregnant women with poor relationship with partner and high socio-economic status had an OR of 13.48 (95 % CI 1.71, 106.31) for antenatal depression. "Reference" pregnant women were those with very good relationship with partner and high socio-economic status. High proportion of self-reported depression among select pregnant women attending antenatal clinics in Mwanza, Tanzania merit integrating depression assessment into existing antenatal care services. Health care providers need to assess pregnancy-related risk factors (pregnancy-related anxiety), socio-demographic factors (socio-economic status), and interpersonal risk factors (relationship with partner). Future research should appraise effectiveness of interventions that enhance partner relationships in reducing antenatal depression across all wealth distributions

Access and utilization of water and sanitation facilities and their determinants among pastoralists in the rural areas of northern Tanzania

Introduction: Lack of safe water, sanitation and hygiene remains one of the most pressing global health issues of our time. Water and sanitation-related improvements are crucial in meeting the Global Sustainable Development Goals. This study was conducted to determine the access, utilization, and determinants of access to sanitation facilities among pastoral communities in rural areas of northern Tanzania.Methods: This cross-sectional study was carried out in Ngorongoro Conservation Area of Ngorongoro District in northern Tanzania. The survey included key measures adapted from the Joint WHO/UNICEF Core Questions on drinking-water and sanitation for Household Surveys. An observation checklist was also completed at each household. Geographical positions of the households were recorded using a Global Positioning System.Results: A total of 175 households participated in the study. More than half (61.7%, n=108) of the participants reported access to an improved water source throughout the year. The majority (50.3%, n=88) of the households reportedly practised open defecation. The multivariate analysis identified that the key determinants to access a sanitation facility at a household were socio-economic status, family size, the presence of under-five years of age in the household, history of diarrhoeal diseases – self-reported of an adult, having ever received education on sanitation and motivation for improvement in defecation place.Conclusion: There is limited access to water and sanitation facilities in communities in the Ngorongoro Conservation Area. Individual and community factors are key determinants for a household to own a sanitation facility. Findings from this study indicate a need for interventions to improve access to water and sanitation facilities in the area.

Contribution of Illicit Drug Use to Pharmaceutical Load in the Environment: A Focus on Sub-Saharan Africa

This research article was published by Hindawi, 2022Illicit drug abuse and addiction are universal issues requiring international cooperation and interdisciplinary and multisectoral solutions. ese addictive substances are utilized for recreational purposes worldwide, including in sub-Saharan Africa. On the other hand, conventional wastewater treatment facilities such as waste stabilization ponds lack the design to remove the most recent classes of pollutants such as illicit drug abuse. As a result, e uents from these treatment schemes contaminate the entire ecosystem. Public health o cials are concerned about detecting these pollutants at alarming levels in some countries, with potential undesirable e ects on aquatic species and increased health hazards through exposure to contaminated waters or recycling treated or untreated e uents in agriculture. Contaminants including illicit substances enter the environment by human excreta following illegal intake, spills, or through direct dumping, such as from clandestine laboratories, when their manufacturer does not follow accepted production processes. ese substances, like other pharmaceuticals, have biological activity and range from pseudopersistent to highly persistent compounds; hence, they persist in the environment while causing harm to the ecosystem. e presence of powerful pharmacological agents such as cocaine, morphine, and amphetamine in water as complex combinations can impair aquatic organisms and human health. ese compounds can harm human beings and ecosystem health apart from their low environmental levels. erefore, this article examines the presence and levels of illicit substances in ecological compartments such as wastewater, surface and ground waters in sub-Saharan Africa, and their latent impact on the ecosystem. e information on the occurrences of illicit drugs and their metabolic products in the sub-Saharan Africa environment and their contribution to pharmaceutical load is missing. In this case, it is important to research further the presence, levels, distribution, and environmental risks of exposure to human beings and the entire ecosystem

Attendance of male partners to different reproductive health services in Shinyanga District, North western Tanzania

Background: Male involvement in reproductive health (RH) services in Africa has been associated with improved maternal and child health outcomes. The objective of this study was to determine the prevalence and factors affecting male partner attendance to available reproductive health services in Shinyanga district, north-western Tanzania.Methods: A house to house survey using a structured questionnaire was conducted among randomly selected married men. Additional in-depth interviews were conducted among married men found attending RH services. Factors that motivates the uptake of locally available RH services together with their partners were explored.Results: A total of 204 men participated in the study, 94.4 % (193/204) of them reported to have ever attended the RH service with their female partners at least once whereas 50.6% (103/204) of them attended at least thrice. Three quarters (154/204) attended HIV counselling and testing (VCT) and 63% (129/204) attended antenatal services (ANC). Reported attendance to sexually transmitted infections (STIs/STDs), prevention of HIV transmission from mother to child (PMTCT), and reproductive health cancer services were all less than 13%.  The male partners age group (25-34 years; χ2=9.347, df =3 p-value < 0.001), female partner invitation to HR services (χ2= 29.901, df=1, p-value <0.001) and having less than 2 children (χ2= 6.201, df= 2, p-value < 0.05) were associated with higher RH service attendance. Only 20% (4/20) of married men attended RH because they expected better health outcomes in their presence whilst majority attended because they were summoned or just happen to be at the clinic for other purposes.Conclusion: The male attendance to RH services together with their female partners’ in rural Shinyanga was mainly focused ANC and VCT. Most of men attended because were verbally invited by their partners. Education on couple communication empowerment among women attending RH clinics could sustainably improve attendance to all RH services.

A Review on Contaminants of Emerging Concern in the Environment: A Focus on Active Chemicals in Sub-Saharan Africa

This research article published by MDPI, 2021: Active chemicals are among the contaminants of emerging concern that are rarely covered in regulatory documents in sub-Saharan Africa. These substances are neither in the list of routinely monitored substances nor in the guidelines for routine environmental monitoring activities. This has been of concern to public health officials, toxicologists, communities, and governments, hence the need for risk assessment and regulation of these substances. In this review article, the presence of active chemicals in the sub-Saharan African environment was investigated. The results indicate the availability of few studies in some countries, while in other countries no reports of active chemicals were found, hence the need for further research targeting such countries. It was further observed that mixtures of active chemicals from different therapeutic categories—such as antibiotics and analgesics—were reported. The natural environment is increasingly at risk due to the presence of these substances, their metabolites, and their transformation byproducts. These substances are characterized by persistence as a result of their non-biodegradable nature; hence, they circulate from one environmental compartment to another through the food chain, causing harm along the way. Most studies that evaluated the toxicity of these substances considered the effects of a single drug, but observations indicated the presence of drug mixtures, hence the need for further evaluation of the effects of drug–drug interactions—including synergistic and additive effects—for environmental sustainability. The presence of ACs in several environmental compartments at quantifiable quantities was discovered in this investigation, indicating the potential for ecosystem injury as a result of bioaccumulation, bioconcentration, and biomagnification through the food chain. This necessitates further research on the subject in order to ensure a healthier environment
