    CLUVA (CLimate change and Urban Vulnerability in Africa; http://www.cluva.eu/) is a 3 years project, funded by the European Commission in 2010. Its objective is to develop context-centered methods to assess vulnerability and increase knowledge on managing climate related risks and to estimate the impacts of climate changes in the next 40 years at urban scale in Africa. The project downscales IPCC climate projections to evaluate threats to selected African test cities; mainly floods, sea-level rise, droughts, heat waves, desertification. It also evaluates and links: social vulnerability; urban green structures and ecosystem services; urban-rural interfaces; vulnerability of urban built environment and lifelines; and related institutional and governance dimensions of adaptation. CLUVA combines assessment approaches to investigate how cities, communities and households can resist and cope with, as well as recover from climate induced hazards. This multi-scale and multi-disciplinary qualitative, quantitative and probabilistic approach of CLUVA is currently being applied to selected African test cities (Addis Ababa - Ethiopia; Dar es Salaam - Tanzania; Douala - Cameroun; Ouagadougou - Burkina Faso; St. Louis - Senegal). In particular, the poster will report on the progresses of the Addis Ababa case study. Addis Ababa, the largest city in Ethiopia, is exposed to heat waves, drought, and, more recently, to flash floods. Due to undulating topography, poor waste management and the absence of sustainable storm water management, Addis Ababa is prone to severe flood events during the rainy seasons. Metropolitan Addis Ababa is crossed by several small watercourses. Torrential rains, very common during the rainy season, cause a sudden rise in the flow of these water courses, inundating and damaging the settlements along their banks and affecting the livelihood of the local population. The combination of climate change and development pressures are expected to exacerbate the

    Cities in Africa show extraordinary expansion of the built environment and imperviousness of the surface condition. Addis Ababa is a case in point, where over the priod of 1984 to 2002, the city asphalted area has increased from 4.72 sq.km (1984) to 27.7 sq.km (2002). Similarly the paved area has expanded five fold from the original 11.1 sq.km, whilst the built environment expanded from 60.1 to 212.7 sq.km. Using hydrological modeling, we demonstrated due to the surface condition change, runoff generation potential has shown significant increase from 28% (in 1984) to 45% (in 2002), showing over 60% change in the runoff volume. The changing condition of the surface is increasing anabtedly, worsening the flooding condition. Similarly, climate change study shows likely increase of precipitation in and around Addis Ababa by about 13 to 17% and comparative increase in flooding. Unlike many cities in Europe, cities in developing countries are confronted with impact emanating from climate change as well as surface condition change. The impact of flooding caused due to the expansion of built environment is found to be more significant in the short term that the climate change, however, the climate change may dominate the long term future of flooding pattern as cities mature towards 2050. Therefore, It is important to view the impacts expansion of built environment and climate change in tandem in future time horizon since the dominance of the impact is different in different temporal scale. In the case of Addis Ababa, we strongly present the following four suggesions: i) the city adminstration re-estabilish the abandoned flood and drainage department of the city as the main flood regulatory and management body working in tandem with Addis Ababa Roads Authority, Water Supply and Sanitation Authority and Urban Planning Authority; ii) The old design guidlines for palnning and design of urban drainage system is not working any more (assumed stationarity condition), we suggest

    Background Collection of household waste is a job which requires repeated heavy physical activities such as lifting, carrying, pulling, and pushing. Like many developing countries, in Ethiopia municipal solid waste is collected manually. Therefore, this study is aimed to assess the extent of occupational injuries and associated factors among solid waste collectors in Addis Ababa City. Methods A cross-sectional study was conducted among 876 respondents sampled from 92 unions. A pre-tested structured questionnaire and observation check list were used to collect data. Crude odds ratio with 95% CI was computed to see the presence of association between selected independent variables and occupational injury. Multivariate logistic regression analysis was made to see the relative effect of independent variable on the dependent variable by controlling the effect of other variables. To maintain stability, only variables that have a p-value less than 0.30 in the binary logistic regression analysis were kept in the subsequent model. Enter method was used hierarchically. Results The response rate of this study was 97.9%. Female respondents accounted 71.2%. The median age of the study subjects was 33 year (with 52 inter quartile range). The overall occupational injury prevalence rate in the last 12 months was 383 (43.7%). Utilization of personal protective devices and family size in the household were statistically associated with injury. As compared to workers who used personal protective equipments while being on duty, odds of injury among workers not used personal protective equipments were 2.62 higher (AOR = 2.62, 95% CI: 1.48-4.63). As compared to those who had five and more children, odds of injuries among those who had 3-4 children was reduced by half (AOR = 0.52, 95% CI: 0.30-0.93). Conclusion The extent of occupational injuries among Addis Ababa city solid waste collectors is present in a level that needs immediate public health action. Implementation of

    Introduction Strengthening Laboratory Management Toward Accreditation (SLMTA) is a competency-based management training programme designed to bring about immediate and measurable laboratory improvement. The aim of this study is to assess the outcome of SLMTA on laboratory quality management system in Addis Ababa, Ethiopia. Methods The study used an Institutional based cross sectional study design that employed a secondary and primary data collection approach on the participated institution of medical laboratory in SLMTA. The study was conducted in Addis Ababa city government and the data was collected from February ‘April 2014 and data was entered in to EPI-data version 3.1 and was analyzed by SPSS version 20. Results The assessment finding indicate that there was a significant improvement in average scores (141.4; range of 65-196, 95%CI =86.275-115.5, p = 0.000) at final with 3 laboratories become 3 star, 6 laboratories were at 2 star, 11 were 1 star. Laboratory facilities respondents which thought getting adequate and timely manner mentorship were found 2.5 times more likely to get good success in the final score(AOR= 2.501, 95% CI= 1.109-4.602) than which did not get it. Conclusion At the end of SLMTA implementation,3 laboratories score 3 star, 6 laboratories were at 2 star, 11 were at 1 star. The most important contributing factor for not scoring star in the final outcome of SLMTA were not conducting their customer satisfaction survey, poor staff motivation, and lack of regular equipment service maintenance. Mentorship, onsite and offsite coaching and training activities had shown a great improvement on laboratory quality management system in most laboratories. PMID:26175805

    Setting The study was conducted in Addis Ababa, the capital city of Ethiopia. Specifically, it was conducted in all healthcare facilities offering maternity and obstetric services. Objective The objective of the study was to explore the patterns of caesarean-section (CS) delivery in Addis Ababa. Methods A cross-sectional survey was carried out between December 2013 and January 2014. The population for the study were women aged between 15 and 19 years of age who had given birth in the last 1–3 years before the date of data collection. The Census and Survey Processing System software was used for data capturing and analysing both descriptive and inferential statistics using Statistical Package for Social Sciences version 20.0. Results Amongst the 835 women who delivered at health facilities, 19.2% had given birth by CS. The prevalence of CS based on medical indication was 91.3%. However, 6.9% of CS performed had no medical indication. Private health facilities performed more CSs than public health facilities, 41.1% and 11.7% respectfully. CS was high amongst women of higher socio-economic standing. Conclusion Overall, CS deliveries rate in Ethiopia is above the rate recommended by the World Health Organisation. Because socio-economic factors influence CS delivery, governments should play a key role in regulating performance of CSs in private institutions. PMID:27542289

    An estimated 95% of the population of Ethiopia uses traditional biomass fuels, such as wood, dung, charcoal, or crop residues, to meet household energy needs. As a result of the harmful smoke emitted from the combustion of biomass fuels, indoor air pollution is responsible for more than 50,000 deaths annually and causes nearly 5% of the burden of disease in Ethiopia. Very limited research on indoor air pollution and its health impacts exists in Ethiopia. This study was, therefore, undertaken to assess the magnitude of indoor air pollution from household fuel use in Addis Ababa, the capital city of Ethiopia. During January and February, 2012, the concentration of fine particulate matter (PM2.5) in 59 households was measured using the University of California at Berkeley Particle Monitor (UCB PM). The raw data was analysed using Statistical Package of Social Science (SPSS version 20.0) software to determine variance between groups and descriptive statistics. The geometric mean of 24-h indoor PM2.5 concentration is approximately 818 μg m-3 (Standard deviation (SD = 3.61)). The highest 24-h geometric mean of PM2.5 concentration observed were 1134 μg m-3 (SD = 3.36), 637 μg m-3 (SD = 4.44), and 335 μg m-3 (SD = 2.51), respectively, in households using predominantly solid fuel, kerosene, and clean fuel. Although 24-h mean PM2.5 concentration between fuel types differed statistically (P < 0.05), post hoc pairwise comparison indicated no significant difference in mean concentration of PM2.5 between improved biomass stoves and traditional stoves (P > 0.05). The study revealed indoor air pollution is a major environmental and health hazard from home using biomass fuel in Addis Ababa. The use of clean fuels and efficient cooking stoves is recommended.

  8. Factors associated with place of death in Addis Ababa, Ethiopia

    2013-01-01

    Background Dying at home is highly prevalent in Africa partly due to lack of accessibility of modern health services. In turn, limited infrastructure and health care deliveries in Africa complicate access to health services. A weak infrastructure and limited health facilities with lower quality in Ethiopia resulted poor health service utilization and coverage, high morbidity and mortality rates. We examined whether people in Addis Ababa died in health facilities and investigated the basic factors associated with place of death. Methods We used verbal autopsy data of 4,776 adults (age>14 years) for the years 2006–2010 from the Addis Ababa Mortality Surveillance Program (AAMSP). The main data source of AAMSP is the burial surveillance from all cemeteries in Addis Ababa. We provide descriptive statistics of place of adult deaths and discussed their covariates using multivariate analyses. Results Only 28.7% died at health facilities, while the remaining died out of health facilities. There was an increase trend in the proportion of health facility deaths from 25.3% in 2006 to 32.5% in 2010. The risk of health facility death versus out of health facility deaths decreased with age. Compared with those who had no education educated people were more likely to die at health facilities. The chance of in health facility death was a little higher for females than males while religion, occupational status and ethnicity of the deceased had no any significance difference in place of death. Conclusion Both demographic and social factors determine where adults will die in Addis Ababa, Ethiopia. The majority of people in Addis Ababa died out of health facilities. The health system should also give special attention to the emerging non communicable diseases like cancer for effective treatment of patients. PMID:23530478

    Between 1990 and 2000, the total fertility rate (TFR) in Ethiopia declined moderately from 6.4 to 5.9 children per woman of reproductive age. During the same period, the TFR in the capital city of Addis Ababa declined from 3.1 to 1.9 children per woman. Even more striking than the magnitude of this decline is that it occurred in the absence of a strong and effective national family planning program. In this study, the components of this fertility decline are identified using the Bongaarts framework of the proximate determinants of fertility. The results of a decomposition analysis indicate that a decrease in the age-specific proportions of women who are married, followed by an increase in contraceptive use are the most important mechanisms by which fertility has declined in Addis Ababa. Poor employment prospects and relatively high housing costs are likely factors that encourage couples to delay marriage and reduce marital fertility. PMID:12772441

    2013-01-01

    Background Sexual abuse of boys is a neglected problem in many developing countries including Ethiopia. As a result, its prevalence, contributing factors and circumstance in which sexual abuse occurs are largely unknown. The objective of this study is to determine the prevalence and factors associated with sexual abuse of male high school students in Addis Ababa city administration. Methods A cross-sectional descriptive study involving 884 randomly selected students of nine high schools in Addis Ababa was conducted in March 2009. A pre-tested questionnaire was used to collect data. Analysis of the data was made using SPSS for windows version 15. Results This study indicates the life time prevalence of rape and sexual harassment of boys in Addis Ababa were 4.3%, and 68.2%, respectively. The chance of experiencing sexual coercion was higher among students who live alone (AOR = 2.87; 95% CI; 1.07, 7.66) and among students who live with others (AOR =1.80; 95% CI = 1.04, 3.11) than those living with both parents. Similarly, the odds of experiencing rape in their life time was higher among students who live with others (AOR=2.20; 95% CI; 1.04, 4.68) than those who live with their parents. Conclusions Sexual abuse of male students is not uncommon in Addis Ababa. It is higher in those living alone or not living with their parents. Due attention is needed by schools, parents and other concerned bodies. Designing a program to fight against sexual abuse should include young school boys. PMID:23680171

    Rapid urbanization, and consequently, the dramatic spatial expansion of mostly informal urban areas increases the vulnerability of African cities to the effects of climate change such as sea level rise, more frequent flooding, droughts and heat waves. The EU FP 7 funded project CLUVA (Climate Change and Urban Vulnerability in Africa, www.cluva.eu) aims to develop strategies for minimizing the risks of natural hazards caused by climate change and to improve the coping capacity of African cities. Green infrastructure may play a particular role in climate change adaptation by providing ecosystem services for flood protection, stormwater retention, heat island moderation and provision of food and fuel wood. In this context, a major challenge is to gain a better understanding of the spatial and temporal dynamics of the cities and how these impact on green infrastructure and hence their vulnerability. Urban growth scenarios for two African cities, namely Addis Ababa, Ethiopia and Dar es Salaam, Tanzania, were developed based on a characterization of their urban morphology. A population growth driven - GIS based - disaggregation modeling approach was applied. Major impact factors influencing the urban dynamics were identified both from literature and interviews with local experts. Location based factors including proximity to road infrastructure and accessibility, and environmental factors including slope, surface and flood risk areas showed a particular impact on urban growth patterns. In Addis Ababa and Dar es Salaam, population density scenarios were modeled comparing two housing development strategies. Results showed that a densification scenario significantly decreases the loss of agricultural and green areas such as forests, bushland and sports grounds. In Dar es Salaam, the scenario of planned new settlements with a population density of max. 350 persons per hectare would lead until 2025 to a loss of agricultural land (-10.1%) and green areas (-6.6%).

    Background Stigma attached to tuberculosis contributes to the limited effectiveness of current TB control approaches. However, there is a dearth of studies that explore the causes of stigma attached to tuberculosis and its effects on patients and tuberculosiscontrol programs in Ethiopia. Methods An institution-based qualitative study was conducted at St. Peter Tuberculosis Specialized Hospital in Addis Ababa, Ethiopia from July to August, 2015. Ten in-depth interviews and 6 key-informant interviews were carried out among tuberculosis patients and healthcare workers, respectively.The Open Code computer software package was used to analyze the data thematically. Results The study revealed that fear of infection and inappropriate health education messages by media were the main causes of tuberculosis stigma. The patients experienced isolation within their family and community, separation, and financial crisis. The stigma attached to tuberculosis may contribute to delayed healthcare seeking, poor treatment adherence, and poor prognosis. Conclusion Interventions thatreduce the stigma attached to tuberculosis should target on areas, such as creating community awareness, patient counseling on problem-solving and emotional skills, preparing culturally sensitive and scientifically sound media messages, providing financial support for the patients, and enhancing the qualities of the healthcare workers, such as empathy, concern, respect for the patient and cultural sensitivity.

    In December 1999, a group of emergency physicians from the United States, Israel, and Ethiopia met for the Second Annual Symposium on Emergency Medicine and to perform an initial evaluation of the prehospital care system in Addis Ababa. The symposium was structured into a workshop on prehospital care and a clinical seminar for emergency medicine providers. This article describes the current prehospital infrastructure in Addis Ababa, Ethiopia. This serves as the basis for more specific needs assessments and training interventions, which are ongoing. The authors present a list of priorities for the development of an emergency medical services (EMS) system for Addis Ababa that was generated in partnership with local government and the World Health Organization. The article contrasts these initial recommendations with those found in the literature on the development of EMS systems in developing nations.

    2013-01-01

    Background Headache disorders are the most common complaints worldwide. Migraine, tension type and cluster headaches account for majority of primary headaches and improvise a substantial burden on the individual, family or society at large. There is a scanty data on the prevalence of primary headaches in sub-Saharan Africa in general and Ethiopia in particular. Moreover there is no population based urban study in Ethiopia. The purpose of this study is to determine the prevalence and burden of primary headaches in local community in Addis Ababa, Ethiopia. Methods Cross-sectional sample survey was carried out in Addis Ketema sub city, Kebele 16/17/18 (local smallest administrative unit). Using systematic random sampling, data were collected by previously used headache questionnaire, over a period of 20 days. Results The study subjects were 231 of which 51.5% were males and 48.5% were females. The overall one year prevalence of primary headache disorders was 21.6% and that for migraine was 10%, migraine without aura 6.5% migraine with aura was 2.6% and probable migraine was 0.9%. The prevalence of tension type of headache was found to be 10.4%, frequent episodic tension type headache was 8.2% followed by infrequent tension type headache of 2.2%. The prevalence of cluster headache was 1.3%. The burden of primary headache disorders in terms of missing working, school or social activities was 68.0%. This was 78.3% for migraineurs and 66.7% for tension type headache. Majority 92.0% of primary headache cases were not using health services and 66.0% did not use any drug or medications during the acute attacks and none were using preventive therapy. Conclusion Prevalence and burden of primary headache disorders was substantial in this community. Health service utilization of the community for headache treatment was poor. PMID:23574933

    Background. The social and economic changes taking place in developing countries are influencing the pace at which hypertension and its risk factors are expanding. As opposed to the already established inverse association in developed nations, the association between socioeconomic status and hypertension in developing countries is poor and inconsistent. This study aims to determine the association between socioeconomic status and hypertension among teachers and bankers in Addis Ababa, Ethiopia. Methods. This study is based on a cross-sectional study conducted to assess the prevalence of NCDs in Addis Ababa, Ethiopia. The study was undertaken among workers of the Commercial Bank of Ethiopia and teachers of public schools in 2010. Results. Majority of participants were teachers (70.3%). Most of the respondents (54.1%) earn an annual income between 15,000 ETB and 48,000 ETB, and 51.9% of them have educational status of first degree and above. Among the socioeconomic factors income was strongly associated with the odds of having hypertension (AOR: 2.17 with 95% CI: 1.58-2.98). Conclusions. Higher burden of hypertension is observed among teachers and bankers in Addis Ababa, Ethiopia. Promotion of healthy behaviors and interventions that target higher income groups needs to be put in place. PMID:27313874

    Setting: The emergency department (ED) of Zewditu Memorial Hospital, Addis Ababa, Ethiopia. Objective: To document the proportion, trend, characteristics and outcomes of road traffic injury (RTI) related ED admissions (⩾15 years) between 2014 and 2015. Design: A retrospective, cross-sectional study using routinely collected ED data. Results: Of 10 007 ED admissions, 779 (8%) were RTI cases; this proportion peaked in the month of January (11%). Medical records were available for 522 (67%) of these RTI cases. The median age was 28 years and 69% were males. The majority were pedestrians (69%) injured by an automobile (78%). On triage, 32% were classified as needing urgent/immediate intervention. Head injuries (20%) were the second most common injury after lower limb injuries (36%). ED outcomes were as follows: discharged (68%), hospitalised (17%), referred (17%) and died (1%). Among the 78 hospitalised cases, respectively 62% and 16% were admitted to the surgical and orthopaedic departments. Of 146 RTI cases with head injuries, 25% were hospitalised, of whom 82% were admitted to the surgical department. Conclusion: Our findings can guide policy makers in referral hospitals in improving the planning of hospital resources and the prioritisation of public health needs linked to further urban development. A comprehensive plan to prevent RTIs, particularly among pedestrians in Addis Ababa, is urgently needed. PMID:27358798

    Fast population growth and rapid industrialization, on one hand, and lack of sewerage network and poor living condition, on the other, have led to the deterioration of surface and ground water quality in the city of Addis Ababa. The urban wastewater is discharged largely into streams that drain the city. Only less than 3% join the wastewater treatment facilities. Due to sporadic rainfall that causes shortage in groundwater recharge, managed aquifer recharge (MAR) experiment was tested on soil column collected from Akaki Well Field which is located in the southern part of the city using water from the Big Akaki River that crosses the same well field and effluent from Kaliti Wastewater Treatment Plant. Water quality analysis for 17 different parameters was done for both the inflow and outflow water samples and soils were tested for electrical conductivity and cation exchange capacity. The results indicate improved water quality as a result of higher attenuation/filtration capacity of the vadose zone in the well field due to the presence of vertisols. The main geochemical processes that have acted in the soil column could be cation exchange, dissolution, precipitation, oxidation, nitrification, die off etc. that are responsible for the effectiveness of vadose zone for MAR.

    Prevalence of Toxoplasma gondii in free-range chickens (Gallus domesticus) is a good indicator of the environmental contamination with oocysts because chickens become infected mainly by feeding from ground, feed, or soil contaminated with oocysts. The seroprevalence of T. gondii antibodies in 125 free-range chickens from the Addis Ababa, Ethiopia, was determined. Antibodies to T. gondii were assayed by the modified agglutination test; 48 of 125 (38.4%) chickens were seropositive, with titers of 1:5 in 14, 1:10 in 12, 1:20 in 14, 1: 40 in 3, 1: 80 in 1, 1:160 in 1, 1:320 in 1, and ≥1:640 in 2 chickens. The hearts of 115 chickens were bioassayed for T. gondii infection. Hearts of 72 seronegative (modified agglutination test [MAT] < 1:5) chickens were pooled in 4 groups (20 + 18 + 19 + 15) and fed to 4 T. gondii -free cats; none of these 4 cats shed oocysts in their feces examined 3-21 days after feeding chicken tissues. Hearts of 43 seropositive chickens (MAT ≥ 1:5) were bioassayed individually in mice. Toxoplasma gondii was isolated from only 1 chicken, with a MAT titer of 1:80. This isolate was designated TgCKEt1 and was not pathogenic for outbred mice. Restricted fragment length polymorphism (RFLP) genotyping using 10 loci indicated the TgCKEt1 was ToxoDB polymerase chain reaction-RFLP genotype #1 (Type II clonal). Results of this study indicate very low environmental contamination with T. gondii oocysts around Addis Ababa.

    Background: In countries like Ethiopia where the spread of HIV infection is extensive, health services are faced with an increased demand for care. The most obvious reflection of this increased demand is through patient load, longer bed occupancy perhaps to the exclusion of patients with other ailments. Objective: The purpose of this study was to describe the bed occupancy rate and the average length of stay of HIV/AIDS inpatients of three major public hospitals. Methods: A Retrospective Cross-sectional study was conducted in three major hospitals of Addis Ababa namely Zewditu Memorial Hospital, Tikure Anbessa Hospital and Saint Paul’s Hospital from February to March 2004. Results: Of the total 453 sampled inpatients, 293 (65 %) were HIV positives. Over half (55.0%) were Males. The most affected age group was between 24 and 56 years. The majority (85.8%) were from Addis Ababa and over half (57.7%) was married. Housewives constituted about a quarter (26.3%) of all the admitted cases. The most common co-morbidities resulted in admission to the medical wards among the HIV-positive cases were Tuberculosis (73.0%) and jirovicii pneumonia (70.3%), and their occurrence was significantly higher among HIV+ than their counter parts (p=0.001). Although numbers of patients admitted in Tikur Anbesa hospital was more than Saint Paul’s and Zewditu Memorial hospitals (ZMH), the proportion of HIV positive cases admitted to ZMH however was higher (49.0%) than Tikur Anbessa (14.0%) and Saint Paul’s hospitals (18.0%). Likewise the number of inpatient days was also higher in ZMH (n=7765) than the other hospitals. The bed occupancy rate was however, higher in ZMH (53.0%) than Tikur Anbessa (12.0%) and Saint Paul’s (12.0%) hospitals. Conclusion: One of the most obvious consequences of HIV/AIDS patients are the increased occupancy of hospitals beds suggesting that only 81.1 % of the beds are for all other afflictions in the hospitals. It appears that there is a lot of concern that

    Demographic transition theory states that fertility declines in response to development, thus wealth and fertility are negatively correlated. Evolutionary theory, however, suggests a positive relationship between wealth and fertility. Fertility transition as a result of industrialization and economic development started in the late 19th and early 20th centuries in Western Europe; and it extended to some of the Asian and Latin American countries later on. However, economic crises since the 1980s have been co-incident with fertility decline in sub-Sahara Africa and other developing countries like Thailand, Nepal and Bangladesh in the last decade of the 20th century. A very low level of fertility is observed in Addis Ababa (TFR=1.9) where contraceptive prevalence rate is modest and recurrent famine as well as drought have been major causes of economic crisis in the country for more than three consecutive decades, which is surprising given the high rural fertility. Detailed socioeconomic and demographic characteristics of 2976 women of reproductive age (i.e. 15-49 years) residing in Addis Ababa were collected during the first quarter of 2003 using an event history calendar and individual women questionnaire. Controlling for the confounding effects of maternal birth cohort, education, marital status and accessible income level, the poor (those who have access to less than a dollar per day or 250 birr a month) were observed to elongate the timing of having first and second births, while relatively better-off women were found to have shorter birth intervals. Results were also the same among the ever-married women only model. More than 50% of women currently in their 20s are also predicted to fail to reproduce as most of the unmarried men and women are 'retreating from marriage' due to economic stress. Qualitative information collected through focus group discussions and in-depth interviews also supports the statistical findings that poverty is at the root of this collapse

    Limited access to modern contraceptives in populations that desire smaller families can lead to repeat unintended pregnancy and repeat abortions. We conducted an analysis of the medical records of 1,200 women seeking abortion-related services in public and private facilities in Addis Ababa, Ethiopia from October 2008 to February 2009. We examined the characteristics of initial and repeat abortion clients including prior contraceptive use and subsequent method selection. The incidence of repeat abortion was 30%. Compared with women seeking their first abortion, significantly more repeat abortion clients had ever used contraceptives and they were nearly twice as likely to leave the facility with a method. However, repeat abortion clients were significantly more likely to have ever used short-term reversible methods and to choose short-term methods post-abortion. Contraceptive counseling services for repeat abortion clients' should address reasons for previous contraceptive failure, discontinuation, or non-use. Post-abortion family planning services should be strengthened to help decrease repeat abortion. PMID:24558782

    There are not many studies of gallbladder disease in Africa. The disease appears to be not uncommon in Ethiopia. To determine the prevalence and evaluate the management of gallstone disease in a central teaching hospital, a 5-year retrospective study was undertaken in 747 patients surgically treated for gallbladder disease in the period 1995-99 in Tikur Anbessa Hospital, Addis Ababa. The sex ratio (M:F) was 1:5, narrower ratio in complicated cholelithiasis. The mean age was 42 years. About 80% of patients were in the age group between 30 and 60 years. The median duration of symptoms at admission was 2 years. Abdominal pain, in 96% of cases situated in the right upper quadrant (RUQ) and usually aching type, was the most frequent presenting symptom; RUQ tenderness was the most common sign. Clinically, 29.4% of patients were categorized obese. Gallstone detection rate by ultrasound was about 96% but cholecystitis appeared to be overlooked. At operation, about 77% of cases had features of chronic cholecystitis, 2% acalculous cholecystitis. Majority of the stones were grossly cholesterol stones. Cholecystectomy was performed in 99% of cases, most often through the oblique subcostal and transverse routes. The overall in-hospital mortality rate was 0.4%. Nearly 87% of cases had postoperative course without incident. The etiologic factors and the type of gallstones, we believe, are not different from that of the developed world. Cholecystectomy is a safe and most effective procedure that provides ultimate cure for symptomatic gallstone disease. PMID:17447363

    Setting: Ethiopia is one of the high multidrug-resistant tuberculosis (MDR-TB) burden countries. Efforts by the National TB Programme to control MDR-TB include expanding ambulatory care. Objective: To investigate the opportunities and challenges faced by treatment follow-up health centres (TFCs) when managing MDR-TB patients, with greater focus on recording, TB infection control (IC) and supervision practices. Methods: A facility-based cross-sectional study was conducted by reviewing the records of all MDR-TB cases in all 25 TFCs in Addis Ababa, Ethiopia. The TB focal point, pharmacy and laboratory heads were also interviewed. Result: A total of 221 MDR-TB patients were registered; 157 (71%) patients had been referred from one of the two treatment initiating centres. While some TFCs oversaw up to 41 patients, others had just one patient. The majority of the TFCs (n = 21, 84%) followed standardised TB IC procedures. Poor documentation of patient information was observed at all sites; for example, human immunodeficiency virus and current treatment status was not indicated for respectively 86 (38%) and 41 (18%) patients. Conclusion: The study revealed that infection prevention practices were largely adhered to. Documentation of patient-related information was a major challenge, and regular supervision of the TFCs should be emphasised. Record keeping is critical. PMID:26478512

    This study (March 1977-February 1978) was performed at the Ethio-Swedish Pediatric Clinic, Addis Ababa, to determine whether there were any seasonal fluctuations in the occurrence of diarrhoea associated with enterotoxigenic enterobacteria (ETEB), rotavirus and two parasites (Giardia lamblia and Entamoeba histolytica).A total of 1161 children (962 patients and 199 controls) were investigated. ETEB were isolated in 12.2% of the patients and 4.5% of the controls, rotavirus in 27.8% and 8%, and parasites in 6.8% and 1%, respectively. There is a statistically significant difference in the isolation rates between patients and controls (P<0.001 for rotavirus, P<0.01 for ETEB and parasites). Rotavirus was most prevalent in the 7-12 months age group and ETEB during the second year of life, while parasites showed a continuous increase with age.Two peaks in the occurrence of ETEB were found during the year, the first in August (32.6%), the second in January (19.2%). Two peaks for rotavirus though not as distinct as for ETEB, were seen in June (42.7%) and November (36.4%). The isolation rate of parasites showed no consistent pattern during the year.This study suggests a seasonal occurrence of ETEB and rotavirus but with no apparent correlation to climatological factors.

    Background Despite the presence of high impact interventions to improve infant and young child feeding, only about 52% of mothers in Ethiopia exclusively breastfeed their child for the first six months after delivery. Although the decision to breastfeed a child is ultimately that of the mother, this decision could be influenced by a variety of factors including social-cognitive ones. Objectives The objectives of the study were to describe the breastfeeding behaviour of primiparous mothers during their prenatal period in terms of intentions/goals, outcome expectancies, self-efficacy, and socio-structural factors and assess their exclusive breastfeeding (EBF) practices as well as identify the social-cognitive predictors of EBF practices among these mothers in Addis Ababa, Ethiopia. Methods A prospective follow up health facility-based study with quantitative methods was used with a sample of 233 primiparous women. Both structured and semi-structured questions were used for collection of data. The Statistical Package for Social Sciences (SPSS) version 21 was used for data analysis. Findings at the 95% confidence interval and P-value of 5% were reported as statistically significant. Results 39.1% (n = 59) of the respondents were found to have high breastfeeding self-efficacy, 51.4% (n = 71) have good breastfeeding outcome expectancies, and 6.5% (n = 9) respondents had supportive breastfeeding socio-structural factors. Bivariate correlation analysis showed positive and statistically significant correlation between each of breastfeeding self-efficacy, outcome expectancy, and socio-structural factors, with EBF practice. However, only breastfeeding self-efficacy and outcome expectancies were statistically significant predictors of EBF among the primiparous women when controlling for confounding variables. Conclusions and Recommendations Health programmes aimed at improving EBF among primiparous mothers should look beyond providing health information alone. Rather improving

    Objective To better understand hospital infection control practices in Ethiopia. Design A cross-sectional evaluation of healthcare worker (HCW) knowledge, attitudes and practices about hand hygiene and tuberculosis (TB) infection control measures. Methods An anonymous, 76-item questionnaire was administered to HCWs at two university hospitals in Addis Ababa, Ethiopia. Knowledge items were scored as correct/incorrect. Attitude and practice items were assessed using a Likert scale. Results 261 surveys were completed by physicians (51%) and nurses (49%). Fifty-one percent of respondents were male; mean age was 30 years. While hand hygiene knowledge was fair, self-reported practice was suboptimal. Physicians reported performing hand hygiene 7% and 48% before and after patient contact, respectively. Barriers for performing hand hygiene included lack of hand hygiene agents (77%), sinks (30%), proper training (50%), and irritation and dryness (67%) caused by hand sanitizer made per WHO formulation. TB infection control knowledge was excellent (>90% correct). Most HCWs felt at high risk for occupational acquisition of TB (71%) and that proper TB infection control can prevent nosocomial transmission (92%). Only 12% of HCWs regularly wore a mask when caring for TB patients. Only 8% of HCWs reported masks were regularly available and 76% cited a lack of infrastructure to isolate suspected/known TB patients. Conclusions Training HCWs about the importance and proper practice of hand hygiene along with improving hand sanitizer options may improve patient safety. Additionally, enhanced infrastructure is needed to improve TB infection control practices and allay HCW concerns about acquiring TB in the hospital. PMID:24225614

    This study presents Global Positioning System-Total Electron Content (GPS-TEC) observations over Addis Ababa (Lat: 9.03°N Lon: 38.77°E Mag. lat: 0.18°N) and an evaluation of the accuracy of International Reference Ionosphere-2012 (IRI-2012) model predictions during 2010-2013. Generally, on a diurnal scale, TEC recorded minimum values at 0400-0600 LT and maximum at 1400-1600 LT. Seasonally, TEC recorded maximum values during December solstice and September equinox, and minimum during June solstice. On a year-by-year basis, 2013 recorded the highest values of TEC for both the observed and the model measurements, while 2010 recorded the lowest, implying the solar activity dependence of TEC. Furthermore, we observed discrepancies in the comparison of the GPS-TEC measurements with those derived from IRI-2012 model, after the exclusion of the contributions of plasmaspheric electron content (PEC) from the GPS-observed TEC. All the three options of IRI-2012 model overestimated TEC during early morning and post-sunset hours. Comparatively, of the three options of IRI-2012 model, NeQuick appears to be the most accurate for TEC estimation over Addis Ababa, although at a very close performance capability with the IRI01 CORR option, while IRI2001 is the least accurate.

    Background Understanding the full range of sexual behaviors of young people is crucial in developing appropriate interventions to prevent and control sexually transmitted infections including HIV. However, such information is meager in developing countries. The objective of this study was to describe oral and anal sex practices and identify associated factors among high school youth. Methods A cross-sectional study was conducted among high school youth in Addis Ababa, Ethiopia. A multi-stage sampling procedure was followed to select a representative sample of school youth. The total sample size for this study was 3840. Data were collected using a self-administered questionnaire. Data analysis was guided by the ecological framework. Results The overall proportion of people who reported ever having oral sex was 5.4% (190) and that of anal sex was 4.3% (154). Of these 51.6% (98) had oral sex and 57.1% (87) had anal sex in the past 12 months. Multiple partnerships were reported by 61.2% of the respondents who had oral sex and 51.1% of students practicing anal sex. Consistent condom use was reported by 12.2% of those practicing oral sex and 26.1% of anal sex. Reasons for oral and anal sex included prevention of pregnancy, preserving virginity, and reduction of HIV and STIs transmission. Oral sex practice was strongly and significantly associated with perception of best friends engagement in oral sex (AOR = 5.7; 95% CI 3.6-11.2) and having illiterate mothers (AOR = 11.5; 95%CI 6.4-18.5). Similarly, anal sex practice was strongly and significantly associated with favorable attitude towards anal sex (AOR = 6.2; 95%CI 3.8-12.4), and perceived best friends engagement in anal sex (AOR = 9.7; 95%CI 5.4-17.7). Conclusion Considerable proportion of adolescents had engaged in oral and anal sex practices. Multiple sexual partnerships were common while consistent condom use was low. Sexual health education and behavior change communication strategies need to cover a full range of

    For cultural reasons modern contraception has been slow to gain acceptance in Ethiopia. Knowledge about contraception and abortion is still limited in many family and community settings in which it is socially disapproved. By 1990 only 4% of Ethiopian females aged 15-49 used contraception. Little is known of sexually transmitted disease (STD) prevalence in family planning (FP) attenders in Africa in general and Ethiopia in particular, even though attenders of family planning clinics (FPCs) are appropriate target groups for epidemiological studies and control programmes. A study of 2111 women of whom 542 (25.7%) attended FPCs in Addis Ababa showed utilisation rates to be highest in women who were: Tigre (33%) or Amhara (31%), aged 20-34 years (30%), age 16 or older at first marriage/coitus (28%:38% in those first married after 25 years); who had a monthly family income of 10 Ethiopian Birr (EB) or more (33%:36% for those with income 100-500 EB), three or more children (37%), more than five lifetime husbands/sexual partners (39%); or were bargirls (73%) or prostitutes (43%). The seroprevalence rates for all STDs, higher in FPC attenders compared with other women, were syphilis (TPHA) 39%, Neisseria gonorrhoeae 66%, genital chlamydia 64%, HSV-2 41%, HBV 40% and Haemophilus ducreyi 20%. Only 4% of FPC attenders had no serological evidence of STD: 64% were seropositive for 3 or more different STD. Clinical evidence of pelvic inflammatory disease (PID) was also more common in the FPC attenders (54%), 37% having evidence of salpingitis. The FPC provides a favourable setting for screening women likely to have high seroprevalence of STD, who for lack of symptoms will not attend either an STD clinic nor a hospital for routine check up. We recommend that measures be taken to adequately screen, treat and educate FPC attenders, their partners, and as appropriate and when possible their clients, in an attempt to control STDs and ultimately HIV in the community.

Les diagnostics d’admission les plus fréquents du type 2 étaient l’ulcère diabétique du pied (39%) et les problèmes cardiovasculaires (21%), et celui du type 1, l’acidocétose diabétique (62%). L’hypertension, les neuropathies, les néphropathies, la rétinopathie et le pied diabétique représentaient 85% des 756 complications existantes. La mortalité totale des patients admis a été de 21%. Sur ces 89 décès, 77 patients étaient de type 2 avec comme indications principales d’admission l’ulcère diabétique du pied/la gangrène et les problèmes cardiovasculaires.Conclusion : Le DM, surtout de type 2, est une cause importante d’admission dans le plus grand hôpital de référence du pays. De nombreux patients avaient déjà développé des complications liées au DM lors de l’admission, et la mortalité a été élevée. Il est nécessaire d’améliorer la connaissance et les soins relatifs au DM en Ethiopie.

Si certains TFC ont suivi jusqu'à 41 patients, d'autres n'ont vu qu'un patient. La majorité des TFC (n = 21, 84%) ont suivi les procédures standardisées de lutte contre l'infection TB. Dans tous les sites, on a observé une documentation insuffisante des informations relatives aux patients. Le statut à l'égard du virus de l'immunodéficience humaine et le traitement en cours n'étaient, par exemple, pas indiqués pour 86 (38%) et 41 (18%) patients, respectivement.Conclusion : L'étude a révélé que les pratiques de prévention de l'infection étaient largement observées. Le principal défi résidait en la documentation des informations relatives aux patients ; la supervision régulière des TFC devrait également être renforcée. La bonne tenue des dossiers est cruciale.

  20. Urban food insecurity in the context of high food prices: a community based cross sectional study in Addis Ababa, Ethiopia

    2014-01-01

    Background High food prices have emerged as a major global challenge, especially for poor and urban households in low-income countries such as Ethiopia. However, there is little empirical evidence on urban food security and how people living in urban areas are coping with sustained high food prices. This study aims to address this gap by investigating the food insecurity situation in urban Ethiopia -a country experiencing sustained high food prices, high rates of urban poverty, and a growing urban population. Methods A community based cross-sectional study was conducted from January 18 to February 14, 2012. A total of 550 households were selected from three sub-cities of Addis Ababa using three-stage sampling technique. Data were collected using questionnaire based interview with household heads. Items in the questionnaire include, among others, basic socioeconomic variables, dietary diversity and coping strategies. Food security status of households was assessed by a Household Food Insecurity Access Score. Data analysis was done using SPSS software and both univariate and bivariate analysis were done. Results The study found that 75% of households were food insecure and 23% were in a state of hunger. Households with higher food insecurity scores tend to have lower dietary diversity and are less likely to consume high quality diets. Reduction in meal size and shifting to poor quality/less expensive/food types were among the common coping strategies to high food price used by households. Household incomes, occupational and educational status of household heads were significant determinants of food security. Conclusion Food insecurity in Ethiopia is not only a rural problem. Urban food insecurity is a growing concern due to the toxic combination of high rates of urban poverty, high dependency of urban households on food supplied by the market, and fluctuating food prices. Household food insecurity was particularly high among low income households and those headed by

    Last decades, new records were set in the world for tornadoes, drought, wind, floods, wildfires and hot temperatures, testifying unusual weather and climate patterns with increasing frequency and intensity of extreme weather events. Extreme heat events are natural hazards affecting many regions in the world, nevertheless limited work has been done on the analysis and effects of extreme heat events in Africa, that is considered a continent particularly vulnerable to the effects of climate change. In fact, the increase of temperature expected in the African continent during the 21st century is larger than the global mean warming, being about 3° to 4° C, about 1.5 times the global temperature increase (Christensen et al., 2007; Gualdi et al., 2012), with the subtropical regions projected to warm more than the tropical regions. Observations and downscaled model simulations (RCP4.5 and RCP8.5 IPCC scenarios) are analyzed to describe heat wave characteristics in Dar es Salaam (Tanzania) and Addis Ababa (Ethiopia), spanning the last five decades as well as that projected for the 21st century. Observed data are daily maximum and minimum temperature collected in the period 1961-2011; downscaled model simulations span up to 2050. Heat waves are defined following a peak over threshold approach by statistical comparison to historical meteorological baselines (site dependent), using a fixed absolute threshold. Projected future warming in the Dar es Salaam and Addis Ababa shows a further increase in the heat waves parameters. Heat wave duration and hot days number are strictly correlated showing that the temperature rise could generate not only an increase of heat waves number but mainly a longer average duration, that can strongly affect the resilience capacity of the population, particularly the elder people. In fact, the impacts of heat waves on the society are determined also by temporal duration (Stephenson, 2008), in addition to their frequency, in fact the capacity of

    Background Even though remarkable progress has been achieved, HIV/AIDS continues to be a major global health priority. HIV discordant relationship is one of the emerging issues in HIV prevention endeavour. In Ethiopia, very little is known about HIV-serodiscordant couples particularly how they manage their sexual relationship and fertility desire. Therefore, we conduct this study with the aim of exploring the experiences of HIV discordant couples about their sexual life, and fertility desire in the context of long-term relationships in Addis Ababa, Ethiopia. Methods A grounded theory approach was employed using in-depth interviews among 36 informants in ART/PMTCT centers of three public hospitals, a health center and one PLHIV association in Addis Ababa. Theoretical sampling was used to recruit 28 clients who lived in a discordant relationship and eight health care providers as key informants. Data collection and analysis were undertaken simultaneously using a constant comparison. The analysis was facilitated using OpenCode software. Results A grounded theory pertaining to sexual life and desire to have a child among HIV discordant couples emerged as “maintaining the relationship” as a core category. Couples pass through a social process of struggle to maintain their relationship. The causal conditions for couples to enter into the process of struggle to maintain their relationship were collectively categorized as “Entering in-to a transition” (knowing HIV serostatus) and this includes mismatch of desire to have a child, controversy on safe sex versus desire to have a child, and undeniable change in sexual desire and practice through time were the features in entering into-transition. Then after the transition, couples engaged in certain actions/strategies that are categorized as “dealing with discordancy” such as entertaining partner’s interest by scarifying once self interest to maintain their relationship. Conclusions HIV discordant couples

    This paper examines the non-prescription use of the sexual enhancement drug Viagra by young men in Addis Ababa. Data was collected through repeated in-depth interviews with 14 Viagra users - heterosexual men between the ages of 21 and 35 - and focus-group discussions with 21 male and 22 female university students. Study participants turned to Viagra to impress lovers, as a 'support mechanism' when feeling weak or tired, to counteract the effects of chewing the stimulant plant khat and to satisfy what they perceived as a psychological 'addiction'. More generally, young men used Viagra to quell anxieties about what they perceived as women's growing expectations about their sexual performance - informed by changing gender relations and sexual expectations, constructions of masculinity that emphasise sexual prowess, and a misreading of women's sexual desires largely fuelled by the emergence of pornography as a new standard for sexual performance. While some men gained sexual confidence by using Viagra, others - particularly those who used Viagra regularly - paradoxically experienced feelings of loss of manhood. PMID:26555512

    Mortality audits are being used with increasing frequency to improve health outcomes by pinpointing precisely where deficiencies in clinical care exist. We conducted a prospective audit of stillbirths and early neonatal deaths at Tikur Anbessa Hospital in Addis Ababa, Ethiopia, as part of a broader initiative to reduce perinatal mortality in the labor room and neonatal intensive care unit. Out of 1,225 deliveries that took place during the six-month study period, there were 30 stillbirths and 31 early neonatal deaths (PMR 50/1,000). A multi-disciplinary Audit Team was established and convened monthly to review standardized data collection forms that were completed for each death. It was determined that avoidable factors were present in 70% of perinatal deaths. Health worker-related factors were the most common avoidable factors identified (accounting for 84% of avoidable factors identified), followed by patient-related factors (11%) and administrative-related factors (5%). Based on the study findings, quality improvement programs that target gaps in care are being implemented on the hospital's labor room and in the neonatal intensive care unit. PMID:27337856

    Background. Despite its lower sensitivity, smear microscopy remains the main diagnostic method for pulmonary tuberculosis (PTB) in resource-limited countries as TB culturing methods like LJ (Lowenstein-Jensen) are expensive to use as a routine base. This study aimed to evaluate the performance of LED-FM for the diagnosis of PTB in HIV positive individuals. Methods. Cross-sectional study was conducted in Zewditu Memorial Hospital and Teklehaimanot Health Center HIV/ART clinics in Addis Ababa, Ethiopia. Each sample was stained with ZN and Auramine O staining and examined with bright-field microscope and LED-FM microscope, respectively. LJ culture was used as a reference. Results. Out of 178 study participants, twenty-four (13.5%) patients were confirmed as positive for MTB with LJ culture. The yield of ZN microscopy and LED-FM in direct and concentrated sample was 3.9%, 8.4%, 6.2%, and 8.4%, respectively. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of direct ZN microscopy were 29.2%, 100%, 100%, and 90.1%, respectively, and of LED-FM microscopy in direct sputum sample were 62.5%, 100%, 100%, and 94.5%, respectively. Conclusion. LED-FM has better sensitivity for the diagnosis of PTB in HIV positive individuals as compared to conventional ZN microscopy. LED-FM can be used as an alternative to conventional ZN microscopy. PMID:26688753

    Understanding risk factors of problematic gambling is prerequisite to effective intervention design to alleviate the negative consequences of gambling. This study explored the personal, social and environmental risk factors of problematic gambling in four high schools in Addis Ababa, Ethiopia, among students (N = 422) ranging from 12 to 21 years of age. Results from the cross-sectional survey showed that personal feelings (e.g., self-esteem, false perceptions about winning, drug abuse), social factors (e.g., peer influence, parental gambling), and environmental factors (e.g., accessibility of gambling venues, advertisements) were significant correlates of problematic gambling. The study also revealed that men were more at risk for severe problematic gambling than females. Among the identified types of gambling activities, the most prevalent ones were playing cards followed by flipping coin and pool gambling while internet gambling was among the least reported gambling activities. By identifying personal, social and environmental correlates of risky gambling activities this study provides evidence-based information for the systematic design and evaluation of educational interventions to prevent problematic gambling in young people.

    Background. The emergence of multidrug resistant bacterial pathogens in hospitals is becoming a challenge for surgeons to treat hospital acquired infections. Objective. To determine bacterial pathogens and drug susceptibility isolated from surgical site infections at St. Paul Specialized Hospital Millennium Medical College and Yekatit 12 Referral Hospital Medical College, Addis Ababa, Ethiopia. Methods. A cross-sectional study was conducted between October 2013 and March 2014 on 107 surgical site infected patients. Wound specimens were collected using sterile cotton swab and processed as per standard operative procedures in appropriate culture media; and susceptibility testing was done using Kirby-Bauer disc diffusion technique. The data were analyzed by using SPSS version 20. Result. From a total of 107 swabs collected, 90 (84.1%) were culture positive and 104 organisms were isolated. E. coli (24 (23.1%)) was the most common organism isolated followed by multidrug resistant Acinetobacter species (23 (22.1%)). More than 58 (75%) of the Gram negative isolates showed multiple antibiotic resistance (resistance ≥ 5 drugs). Pan-antibiotic resistance was noted among 8 (34.8%) Acinetobacter species and 3 (12.5%) E. coli. This calls for abstinence from antibiotic abuse. Conclusion. Gram negative bacteria were the most important isolates accounting for 76 (73.1%). Ampicillin, amoxicillin, penicillin, cephazoline, and tetracycline showed resistance while gentamicin and ciprofloxacin were relatively effective antimicrobials. PMID:27446213

    Health-related quality of life (HRQoL) is an important outcome measure among HIV-infected patients receiving combination antiretroviral therapy (cART), but has not been studied extensively in resource-limited settings. Insight in the predictors or correlates of poor HRQoL may be helpful to identify patients most in need of additional support and to design appropriate interventions. A cross-sectional study was conducted between September 2012 and April 2013 in 10 healthcare facilities in Addis Ababa, Ethiopia. Patients who were at least 6 months on cART were randomly selected and individual patient data were retrieved from medical records. HRQoL was measured by the WHOQoL-HIVBREF, depressive-symptoms by the Kessler-6 scale, and stigma by the Kalichman internalized AIDS-related stigma scale. Multivariate linear regression analysis was carried-out to examine associations between HRQoL and the other variables. A total of 664 patients (response-rate 95%) participated in the study. A higher level of depressive-symptoms was most strongly and consistently associated with a lower HRQoL, both in terms of the magnitude of the relationship and in the number of HRQoL domains associated with it. Also, a higher level of HIV-stigma was associated with a lower HRQoL except for the physical domain, while obtaining sufficient nutritious food and job opportunity were associated with a better HRQoL except for the spiritual and social domains, respectively. Demographics, clinical, and treatment characteristics yielded few significant associations with HRQoL. Our study findings suggest that interventions to improve HRQoL should focus on reducing depressive-symptoms and HIV-stigma, and on enhancing food security and job opportunity. PMID:25782603

    Samples of vegetables, water and soil were collected from four vegetable farms in Addis Ababa to evaluate the extent and trend of metal accumulation in these systems and health risk concerns to consumers. Vegetable samples were digested in HNO(3) and HClO(4), soil samples in Aqua Regia and water samples were pre-concentrated with methyl isobutyl ketone (MIBK) using the chelating agent ammonium pyrrolidine dithiocarbamate (APDC). All the samples were analyzed for Co, Cr, Cu, Mn, Ni, Zn, Cd and Pb with flame atomic absorption spectrophotometer. The concentrations of Cd (0.12-1.13 mg kg(-1)) and Pb (0.11-0.89 mg kg(-1)) in the vegetables surpassed the maximum recommended levels. The total metal concentrations in soils were (mg kg(-1)): Cr, 9.9-22.8; Co, 28.0-47.3; Cu, 25.1-51.4, Mn, 1000-1054; Ni, 16.4-55.8; Zn, 146-149; Cd, 1.4-1.8 and Pb, 22.0-50.7. The trace metals Cd, Co, Cu, Mn and Ni in most of the water samples collected from Goffa, Kera and Akaki farms also surpassed irrigation water guideline limits, which might be a case for high accumulation of metals in the soils. However, the soil pH (6.5-7.6) and high cation exchange capacity (CEC), 38.41-50.18, coupled with high clay content, 37-51%, of the soil seemed to limit metal uptake by the vegetables. The physical parameters, pH (7.43-7.89) and electrical conductivity (0.33-1.54 dS/m) of irrigation waters measured at 25°C were found within the acceptable range. PMID:22062152

    Our objective in this study was to assess the validity and dependability of the Household Food Insecurity Access Scale (HFIAS), which was developed for international use, among community health volunteers in Addis Ababa, Ethiopia. The HFIAS was translated into Amharic and subsequently tested for content and face validity. This was followed by a quantitative validation study based on a representative sample (n = 99) of female community volunteers (HIV/AIDS home-based caregivers), with whom the HFIAS was administered at 3 time points over the course of 2008, in the context of the local and global "food crisis." By pooling observations across data collection rounds and accounting for intra-individual correlation in repeated measures, we found that the HFIAS performed well according to standards in the field. We also observed slight amelioration in reported food insecurity (FI) status over time, which seems paradoxical given the increasing inaccessibility of food over the same time period due to inflating prices and disappearing food aid. We attempted to resolve this paradox by appealing to self-report-related phenomena that arise in the context of longitudinal study designs: 1) observation bias, in which respondents change their reports according to changing expectations of the observer-respondent relationship or change their behavior in ways that ameliorate FI after baseline self-reports; and 2) "response shift," in which respondents change their reports according to reassessment of internal standards of FI. Our results are important for the validation of FI tools and for the sustainability of community health programs reliant on volunteerism in sub-Saharan Africa. PMID:19640968

    The 2008 food crisis may have increased household food insecurity and caused distress among impoverished populations in low-income countries. Policy researchers have attempted to quantify the impact that a sharp rise in food prices might have on population wellbeing by asking what proportion of households would drop below conventional poverty lines given a set increase in prices. Our understanding of the impact of food crises can be extended by conducting micro-level ethnographic studies. This study examined self-reported household food insecurity (FI) and common mental disorders (CMD) among 110 community health AIDS care volunteers living in Addis Ababa, Ethiopia during the height of the 2008 food crisis. We used generalized estimating equations that account for associations between responses given by the same participants over 3 survey rounds during 2008, to model the longitudinal response profiles of FI, CMD symptoms, and socio-behavioral and micro-economic covariates. To help explain the patterns observed in the response profiles and regression results, we examine qualitative data that contextualize the cognition and reporting behavior of AIDS care volunteers, as well as potential observation biases inherent in longitudinal, community-based research. Our data show that food insecurity is highly prevalent, that is it associated with household economic factors, and that it is linked to mental health. Surprisingly, the volunteers in this urban sample did not report increasingly severe FI or CMD during the peak of the 2008 food crisis. This is a counter-intuitive result that would not be predicted in analyses of population-level data such as those used in econometrics simulations. But when these results are linked to real people in specific urban ecologies, they can improve our understanding of the psychosocial consequences of food price shocks. PMID:20189698

    Obstetric experience, clinical and socio-economic characteristics, and reasons for preference of place of delivery of 639 fistula patients admitted to the Addis Ababa Fistula Hospital between May 1999 and February 2000 are described About 94% of fistula patients were married and 83.6% had been through with the delivery caused the fistula before the age of 20. The mean ages at the first marriage and at the causative delivery were 14.7 (sd=2.6) and 17.8 (sd=3.2) years respectively. Mean height of fistula patients studied was 149 cms (sd=8). About 64% were primiparous, 44% (279) delivered at home, and labor lasted for 3.8 days on average. Majority of fistula patients mentioned distance as a main problem for the delays. Lack of money, poor knowledge and delay in referral were the other frequently mentioned reasons for the delays. About 62%(399) of fistula patients owned nothing valuable. Of 279 patients delivered at home 186 were those who owned nothing. Out of 180-fistula patients mentioned distance as the major problem, 103 (57%) stayed at home for delivery. About 54% of fistula patients were already divorced on arrival to the hospital and this figure varied among women with different parity and among those owning different property. Teenage and short stature are observed features of fistula patients. The study also showed the huge problems faced by fistula patients in accessing emergency obstetric care services. Analytic study is recommended to compare the magnitude of these problems among other mothers with different obstetric outcome. Meanwhile, community education about problems following teenage pregnancy, sign and symptoms of obstructed labor and the advantage of institutional delivery might reduce the occurrence rate of obstetric fistula. Community organized fund and maternity waiting areas for young and short expecting mothers are among other recommendations to be considered. PMID:15884272

    The main objective of this cross-sectional study is to assess higher education students' attitudes, their practice on preventive measures against HIV/AIDS; and examined factors affecting attitude and practice of the students related to HIV/AIDS prevention. The 606 study participants were drawn from Addis Ababa University, which is the oldest and biggest public university in Ethiopia, through multistage sampling. Data were collected using survey quantitative (questionnaire) and qualitative (FGDs), and subsequently, analysis of the data was made through the use of descriptive statistics (Frequency and logistic regression model). The findings of the study revealed that 207 (34.2%) of respondents were sexually active during the survey. Of these, 144 (23.8%) of them had sexual intercourse with their partner or someone in the last 6 months. The mean and median age at first sex debut was computed as 17.8 and 18.0 years respectively. About 489 (80.7%) did not perceive being at risk of contracting HIV/AIDS. But 65.5% of the respondent had favorable attitude on HIV prevention. 359 (59.2%) of the respondents had experienced at least one of the three HIV prevention practice. Of which, more than half (52.4%) adopted abstinence as top preventive measure. The result also showed that out of the total respondents 47.2% had been tested for HIV/AIDS and more than 80% have willingness to take VCT service for HIV/AIDS. As to the multivariate analysis result; sex, previous residence, religious participation, pornographic viewing, currently alcohol intake, chewing khat and cigarette smoking were found to be determinant of AAU students' attitude on HIV prevention. Similarly, age, having pocket money, pornographic film show and currently khat chewing were determinants of practices on HIV prevention. Finally, based on the findings, the study has forwarded some workable recommendations. PMID:22066302

    A cross-sectional study was done from March to May 1997 in four selected slum kebeles (villages) of Addis Ababa in which nutritional status of 758 children aged 6 to 36 months was examined and stratified into malnourished and well nourished groups. Analysis of hygiene and health seeking practices of randomly selected households of the two sets of children determined practices that significantly exacerbate childhood malnutrition. The rates of immunization for the malnourished (80.2%) and well nourished households (77.6%) were practically the same. No significant difference was found in the prevalence of home treatment or food withholding habits at times of diarrhoea episodes between the two groups. The study established six variables to predict childhood malnutrition in the slum section of Addis Ababa: 1) presence of child waste inside house (Odds Ratio = 7.44; p < 0.0001), 2) diarrhoea treatment at the hospital (OR = 0.47;p < 0.05), 3) prolonged storage of cooked foods (OR = 2.86;p < 0.05), 4) feeding with washed hands (OR = 0.44; p < 0.01), and 5) poor handling of drinking water (OR = 3.18; p < 0.01) and 6) foods (OR = 3.52; p < 0.01). Hence strong and sustainable advice with a view of changing the behaviours of households towards good personal and household hygiene practices, and increased utilization of health settings is recommended as these may limit the overall success of public health programmes.

    Children infected with human immunodeficiency virus (HIV) are at particular risk for psychological disturbance. Little is known about the mental health status of children on highly active antiretroviral therapy (HAART). A hospital-based cross-sectional study of 318 children aged 6-14 on HAART in Addis Ababa was conducted. Behavioral and emotional problem was assessed using the child behavior check list (CBCL/6-18). Logistic regression analysis was done to select the best subset of predictor variables and determine their association with behavioral and emotional problems. Of the 318 caregivers of children aged 6-14 on HAART, 39.3% of the children had behavioral and emotional problems. Low family monthly income (AOR, 3.44, 95% CI, 1.89-6.25), older age (AOR, 2.27, 95% CI, 1.34-3.83), and parental loss (AOR, 1.89, 95% CI, 1.10-3.25) were found to be determinants of behavioral and emotional problems in the multivariate logistic regression. There is high prevalence of behavioral and emotional problems in children on HAART in Addis Ababa. More support is needed to children from families of low income and those who lost their parents. Further research should be carried out to enhance better understanding and appropriate response to behavioral and emotional problems.

    Background To facilitate access to the prevention of mother-to-child HIV transmission (PMTCT) services, HIV counselling and testing are offered routinely in antenatal care settings. Focusing a cohort of pregnant women attending public and private antenatal care facilities, this study applied an extended version of the Theory of Planned Behaviour (TPB) to explain intended- and actual HIV testing. Methods A sequential exploratory mixed methods study was conducted in Addis Ababa in 2009. The study involved first time antenatal attendees from public- and private health care facilities. Three Focus Group Discussions were conducted to inform the TPB questionnaire. A total of 3033 women completed the baseline TPB interviews, including attitudes, subjective norms, perceived behavioural control and intention with respect to HIV testing, whereas 2928 completed actual HIV testing at follow up. Data were analysed using descriptive statistics, Chi-square tests, Fisher's Exact tests, Internal consistency reliability, Pearson's correlation, Linear regression, Logistic regression and using Epidemiological indices. P-values < 0.05 was considered significant and 95% Confidence Interval (CI) was used for the odds ratio. Results The TPB explained 9.2% and 16.4% of the variance in intention among public- and private health facility attendees. Intention and perceived barriers explained 2.4% and external variables explained 7% of the total variance in HIV testing. Positive and negative predictive values of intention were 96% and 6% respectively. Across both groups, subjective norm explained a substantial amount of variance in intention, followed by attitudes. Women intended to test for HIV if they perceived social support and anticipated positive consequences following test performance. Type of counselling did not modify the link between intended and actual HIV testing. Conclusion The TPB explained substantial amount of variance in intention to test but was less sufficient in explaining

    Work-related stress is a pattern of reactions to work demands unmatched to nurses' knowledge, skills, or abilities; these challenges exceed their ability to cope, resulting in burnout, turnover, and low quality patient care. An institution-based cross-sectional study of 343 nurses was conducted in public hospitals of Addis Ababa in 2012. Data were collected by pretested and self-administered questionnaires using a nursing stress scale. One hundred twenty-one (37.8%) (95% confidence interval: 34.3 to 39.1) nurses reported experiencing occupational stress. Significant associations were found between nurses' stress and gender, work shift, illness, marital status, and worksite or unit. Prevalence of work-related stress was higher than expected and opportunities exist for stake holders to design stress reduction and management programs for nurses.

  2. Factors associated with success of vaginal birth after one caesarean section (VBAC) at three teaching hospitals in Addis Ababa, Ethiopia: a case control study

    2013-01-01

    Background Vaginal delivery after previous one cesarean section for a non recurring indication has been described by several authors as safe and having a success rate of 60–80%. Hence many centers are offering VBAC for candidates leaving the century old dictum of once cesarean always cesarean. But predicting success of VBAC after trial of labor (TOL) is still a difficult task due to the lack of a validated prediction tool. Studies on predictors of success are few and most of them conducted in developed countries and difficult to generalize. Therefore assessing factors associated with successful VBAC is very important to for counseling mothers while offering VBAC. The aim of this study was to assess factors associated with successful VBAC in three teaching Hospitals in Addis Ababa Ethiopia. Methods A case control study was conducted to compare the factors associated with successful VBAC in teaching hospitals in Addis Ababa in one year period. The cases were those successfully delivered vaginally and the controls were those with failed VBAC and delivered by caesarean section. The sample size of the cases was 101vaginal deliveries and the controls were 103 failed VBAC patients which made the case to control ratio of 1:1. Result In this study independent factors determining successful VBAC were, history of successful VBAC in the past, rupture of membrane at admission, and cervical dilatation of more than 3cm at admission. Presence of meconium, malposition and history of stillbirth were associated with failed VBAC. Factors like maternal age, past caesarean indications, inter delivery interval, and birth weight were not found to be significant determinants of success. The most common reason for repeat cesarean section for after trial of labor was labour dysfunction because of absence of a policy for augmentation on a scarred uterus in these hospitals. Conclusion It is possible to prepare a decision tool on the success of VBAC by taking important past and present

    Tuberculosis (TB) is still a public health problem in sub Saharan African countries. In resource-limited settings, TB diagnosis relies on sputum smear microscopy, with low and variable sensitivities, especially in paucibacillary pediatric and HIV-associated TB patients. Tuberculosis microscopy centers have several weaknesses like overworking, insufficiently trained personnel, inconsistent reagent supplies, and poorly maintained equipments; thus, there is a critical need for investments in laboratory infrastructure, capacity building, and quality assurance schemes. The performance of TB microscopy centers in the private health facilities in Addis Ababa is not known so far. The main objective of the study was to assess laboratory performance of acid fast bacilli (AFB) smear microscopy and its associated factors in selected private health facilities in Addis Ababa, Ethiopia. A cross-sectional study was conducted in 33 selected private health facilities of Addis Ababa, Ethiopia comprising 7 hospitals, 2 NGO health centers, 23 higher clinics and 1 diagnostic laboratory that provide AFB smear microscopy services. The study was conducted from January to April 2014. A total of 283 stained sputum smears were randomly collected from participant laboratories for blinded rechecking, 320 panel slides were sent to 32 microscopy centers to evaluate their performance on AFB reading, staining and reporting. Checklists were used to assess quality issues of laboratories. Data were captured, cleaned, and analyzed using SPSS version 16.0; χ(2) tests, kappa statistics were used for comparison purpose. P value < 0.05 considered statistically significant. Among the 32 participant laboratories, 2-scored 100%, 15 scored 80-95% & the remaining 15 scored 50-75% for overall proficiency test performance.

    2013-01-01

    Background Faculty turn-over affects both workers and organizations. Turnover of faculty and researchers is increasing alarmingly and costing the universities and the country at large. Fast turnover of health professionals from the health system and from academic institutions has recently received substantial attention from both academia and health sector managers. This paper calculates the faculty turnover rate at the College of Health Sciences of Addis Ababa University during the period of September 1991 to August 2011. Methods The study was conducted at the College of Health Sciences, Addis Ababa University. Retrospective analysis of employee records was done. All records of the faculty that were working in the College during the 20-year period, starting from September 1991 to August 2011 were retrospectively reviewed. Data were collected from the employee records accessed from the College’s human resources database and supplemented by payroll sheets and different reports. A structured checklist was used to extract the required data from the database. The crude turnover rate for academic faculty was calculated. Results Within the 20-year period of September 1991 to August 2011, a total of 120 faculty members left. The overall turn-over rate was 92.8 %. The rate in the most recent five years (172 %) is 8.5 times higher than the rate for the first five years (20 %). The average retention period before the termination of an employment contract was 4.9 years. The top five departments where employment contracts were relatively higher include: Nursing 15 (15.6 %), Internal Medicine 12 (12.5%), Public Health 10 (10.4%), Pediatrics 9 (9.4%) and Surgery 9 (9.4%). About two thirds (66.6%) of the faculty who were leaving were at the ranks of assistant professorship and above. Conclusion This study revealed that outflow of faculty has been continuously increasing in the period reviewed. This implies that the College had been losing highly skilled professionals with

    Salmonellae are ubiquitous, found in animals, humans, and the environment, a condition which facilitates transmission and cross contamination. Salmonella enterica serotypes exert huge health and economic impacts due to their virulence or carriage of antibiotic resistance traits. To address this significant issues with regard to public health, availability of adequate information on the prevalence and antibiotic resistance patterns of Salmonella, and establishment of adequate measures to control contamination and infection are needed. A cross-sectional study was conducted to assess the level of Salmonella infection in slaughtered bovines and ovines at Addis Ababa abattoir. Samples were collected randomly and processed for identification and antimicrobial susceptibility testing of Salmonella spp. From 280 animals examined, 13 (4.64%) (8 bovines and 5 ovines) were positive, with most samples (12/13, 92%) comprising Salmonella Dublin. Very high level of resistance to some antibiotics used in human medicine was detected. Most isolates were susceptible to gentamycin and amikacin. Nine (69%) of all isolates were resistant to multiple antibiotics. Serotyping revealed 12 of 13 isolates to be of the Dublin serotype with 9,12:g,p:- antigenic formula. This study emphasizes the importance of improving the evisceration practice during slaughtering and restricting the use of antibiotics in farm animals. PMID:27660816

    Introduction Ethiopia is experiencing an increasingly urban HIV epidemic, alongside a rise in urban adolescent migration. Adolescent migrants are often confronted by unique social challenges, including living in a difficult environment, abuse and mental health problems. These issues can increase adolescents’ vulnerability to HIV and compromise their capacity to protect themselves and others from HIV. We piloted and assessed the effects of a targeted psychosocial intervention to reduce mental health problems and improve HIV-related outcomes among migrant adolescents in Addis Ababa. Methods A pre- and post-comparison design was used in a cohort of 576 female and 154 male migrant adolescents aged 15 to 18 years in Addis Ababa receiving services from two service delivery organizations, Biruh Tesfa and Retrak. We implemented a three-month client-centred, counsellor-delivered psychosocial intervention, based on findings from formative research among the same target population, to address participants’ increased vulnerability to HIV. The intervention package comprised individual, group and creative arts therapy counselling sessions. Key outcome indicators included anxiety, depression, aggressive behaviour, attention problems, social problems, knowledge of HIV, safer sex practices and use of sexual health services. Longitudinal data analysis (McNemar test and random effects regression) was used to assess changes over time in key indicators by gender. Results For females, aggressive behaviour decreased by 60% (adjusted odds ratio (AOR): 0.4 (0.25 to 0.65)) and any mental health problem decreased by 50% (AOR: 0.5 (0.36 to 0.81)) from baseline to end line. In addition, knowledge of HIV increased by 60% (AOR: 1.6 (1.08 to 2.47)), knowledge of a place to test for HIV increased by 70% (AOR: 1.7 (1.12 to 2.51)) and HIV testing increased by 80% (AOR: 1.8 (1.13 to 2.97)). For males, HIV knowledge increased by 110% (AOR: 2.1 (1.1 to 3.94)), knowledge of a place to test for HIV

    Introduction The World Health Organization Regional Office for Africa (WHO AFRO) introduces a step wise incremental accreditation approach to improving quality of laboratory and it is a new initiative in Ethiopia and activities are performed for implementation of accreditation program. Methods Descriptive cross sectional study was conducted in 30 laboratory facilities including 6 laboratory sections to determine their status towards of accreditation using WHO AFRO accreditation checklist and 213 laboratory professionals were interviewed to assess their knowledge on quality system essentials and accreditation in Addis Ababa Ethiopia. Results Out of 30 laboratory facilities 1 private laboratory scored 156 (62%) points, which is the minimum required point for WHO accreditation and the least score was 32 (12.8%) points from government laboratory. The assessment finding from each section indicate that 2 Clinical chemistry (55.2% & 62.8%), 2 Hematology (55.2% & 62.8%), 2 Serology (55.2% & 62.8%), 2 Microbiology (55.2% & 62.4%), 1 Parasitology (62.8%) & 1 Urinalysis (61.6%) sections scored the minimum required point for WHO accreditation. The average score for government laboratories was 78.2 (31.2%) points, of these 6 laboratories were under accreditation process with 106.2 (42.5%) average score, while the private laboratories had 71.2 (28.5%) average score. Of 213 respondents 197 (92.5%) professionals had a knowledge on quality system essentials whereas 155 (72.8%) respondents on accreditation. Conclusion Although majority of the laboratory professionals had knowledge on quality system and accreditation, laboratories professionals were not able to practice the quality system properly and most of the laboratories had poor status towards the WHO accreditation process. Thus government as well as stakeholders should integrate accreditation program into planning and health policy. PMID:26889317

    Health research in Ethiopia is increasing both in volume and type, accompanied with expansion of higher education and research since the past few years. This calls for a proportional competence in the governance of medical research ethics in Ethiopia in the respective research and higher learning institutes. The paper highlights the evolution and progress ofthe ethics review at Addis Ababa University - College of Health Sciences (AAU-CHS) in the given context of health research review system in Ethiopia. Reflections are made on the key lessons to be drawnfrom the formative experiences of the Institutional Review Board (IRB) and their implications to the Ethiopian health research review system. This article is a review paper based on review of published and un published documents on research ethics in Ethiopia and the AAU-CHS (2007-2012). Thematic summaries of review findings are presented in thematic areas - formation of ethics review and key factors in the evolution of ethics review and implications. The IRB at AAU-CHS has been pivotal in providing review and follow-up for important clinical studies in Ethiopia. It has been one of the first IRBs to get WHO/SIDCER recognition from Africa and Ethiopia. Important factors in the successes of the IRB among others included leadership commitment, its placement in institutional structure, and continued capacity building. Financial challenges and sustainability issues need to be addressed for the sustained gains registered so far. Similar factors are considered important for the new and younger IRBs within the emergent Universities and research centers in the country.

    Background The burden of blindness from glaucoma is high. Therefore, people suffering from a serious eye disease such as glaucoma, which can lead to blindness, usually have an emotional disturbance on the patient. Untreated psychiatric illness is associated with increased morbidity and increased costs of care. Objective This study aimed to assess prevalence of common mental disorders and associated factors among people with Glaucoma attending Menelik II referral hospital, Addis Ababa, Ethiopia, 2014. Methods Institution based Cross-sectional study design was conducted in the Department of Ophthalmology Menelik II Referral Hospital from April 10 to May 15, 2014. 423 participants who had undergone through investigation, examination and diagnosed as patients of glaucoma were selected randomly from the glaucoma clinic. Data were collected through face to face interview using Self Reporting Questionnaire consisted of 20 items. Study subjects who scored ≥11 from SRQ-20 were considered as having common mental disorders. Bivariate and multivariable logistic regression analysis with 95% CI were done and variables with P<0.05 in the final model were identified as independent factors associated with common mental disorders. Results Four hundred five patients with glaucoma were included in our study with response rate of 95.7% and 64.5% were males. The average age was 59±13.37 years. Common mental disorders were observed in 23.2% of Glaucoma patients. It is quite obvious that levels of CMDs were high among patients with glaucoma. There was a significant association between age, sex, chronic physical illness, income and duration of illness at P < 0.05. Conclusion and Recommendation Symptoms of common mental disorders were the commonest comorbidities among patients with glaucoma. It will be better to assess and treat Common mental disorders as a separate illness in patients with glaucoma. PMID:27584147

    Introduction Logistics management information system for health commodities remained poorly implemented in most of developing countries. To assess the status of laboratory logistics management information system for HIV/AIDS and tuberculosis laboratory commodities in public health facilities in Addis Ababa. Methods A cross-sectional descriptive study was conducted from September 2010-January 2011 at selected public health facilities. A stratified random sampling method was used to include a total of 43 facilities which, were investigated through quantitative methods using structured questionnaires interviews. Focus group discussion with the designated supply chain managers and key informant interviews were conducted for the qualitative method. Results There exists a well-designed logistics system for laboratory commodities with trained pharmacy personnel, distributed standard LMIS formats and established inventory control procedures. However, majority of laboratory professionals were not trained in LMIS. Majority of the facilities (60.5%) were stocked out for at least one ART monitoring and TB laboratory reagents and the highest stock out rate was for chemistry reagents. Expired ART monitoring laboratory commodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessed hospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDS and TB laboratory commodities in main pharmacy store, among these only 25% and 20.8% of them were updated with accurate information matching with the physical count done at the time of visit for hospitals and health centers respectively. Conclusion Even though there exists a well designed laboratory LMIS, keeping quality stock/bin cards and LMIS reports were very low. Key ART monitoring laboratory commodities were stock out at many facilities at the day of visit and during the past six months. Based on findings, training of laboratory personnel's managing laboratory commodities and keeping

    Background. While effective treatments are available for people with schizophrenia, presence of perceived stigma prevents them from accessing and receiving the help they need to get. Objectives. To assess the prevalence and associated factors of perceived stigma among people with schizophrenia attending the Outpatient Department of Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia. Methods. Institution based cross-sectional study design was conducted among 411 subjects using an Amharic version of the perceived devaluation and discrimination scale. Single population proportion formula was used to calculate sample size. Subjects were selected by systematic sampling techniques. Binary logistic regression and odds ratio with 95% confidence interval were used to identify the association factors of outcome variables. Results. A total of 411 subjects participated in the study giving a response rate of 97.4%. The prevalence of perceived stigma was found to be 83.5%. Education status (not able to read and write) (AOR = 2.64, 95% CI: 1.118, 6.227), difficulties of adherence to antipsychotic drug (AOR = 4.49, 95% CI: 2.309, 8.732), and duration of illness less than one year (AOR = 3.48, 95% CI: 2.238, 5.422) were factors associated with perceived stigma. Conclusion. Overall, the prevalence of perceived stigma was found to be high. Education status (not able to read and write), difficulties of adherence to antipsychotic medication, and duration of illness were factors associated with perceived stigma. Adherence to antipsychotic medication particularly during the early stage of the illness and strengthening the educational status of the participants were suggested in the clinical care setting.

With rising numbers of FSWs in Addis Ketema and concerns about their high risk behaviours, exploring and addressing the barriers to uptake is crucial. This qualitative study explores the barriers to utilising HTC facilities and identifies the motives and motivations of FSWs who seek HTC through in-depth and semi-structured interviews with female sex workers, healthcare workers and key informants. Results indicate that FSWs face numerous barriers including inability to seek treatment if found to be positive due to the requirement of an identity (ID) card many do not own. Many FSWs reported discriminatory behaviour from healthcare workers and a lack of dedicated services. What is clear from the findings is that distinct strategies, which differ from those of the broader population, are required to attract FSWs--strategies which take into account the barriers and maximise the reported motives and motivations for testing.

    Purpose This study was aimed at assessing the extent of dispensing prescription-only medications without a prescription in community drug retail outlets (CDROs) of Addis Ababa, Ethiopia. Methods A descriptive cross-sectional observational study design was used to sample 31 pharmacies, 25 drug stores, and two rural drug vendors from August 11, 2015, to October 21, 2015, through a simple random sampling method. A simulated-patient method of visit was implemented to collect data. Requests of six tracer prescription-only medicines (amoxicillin + clavulanic acid capsule, amitriptyline, captopril, glibenclamide [also known as glyburide], omeprazole capsule, and sildenafil citrate) and upper respiratory tract infection were selected as the simulated clinical scenario. Results Amoxicillin–clavulanic acid capsule was dispensed when requested in 87.93% of the dispensaries. All of the CDROs dispensed omeprazole upon request. Sildenafil citrate (Viagra) was in stock in 96.55% of the CDROs, all of which issued the requested number of tablets without asking why or for whom the drug was needed. Amitriptyline, captopril, and glibenclamide (glyburide) were dispensed in 84.48%, 89.65%, and 87.93% of CDROs upon the provision of an empty container. Antibiotics were obtained from 75.86% of CDROs for presentation of upper respiratory tract infection symptoms. Among the dispensed antibiotics, the most common was amoxicillin (93.18%), followed by amoxicillin–clavulanic acid capsule (72.72%), and azithromycin (50%). Only 4.5% of the dispensaries asked about drug allergies, and 15.9% of the CDROs informed the simulated patient about the possible side effects of the drugs. Conclusion This study revealed a very high rate of dispensing of prescription-only medicines without a prescription. Antimicrobials and drugs for chronic diseases were obtained with ease from almost all of the randomly sampled CDROs. Putting good dispensing practice into effect and adhering to the existing national

    Background To provide quality care at the end of life or for chronically sick patients, nurses must have good knowledge, attitude and practice about palliative care (PC). In Ethiopia PC is new and very little is known about the type of services offered and the readiness of nurses to provide PC. Methods A cross sectional quantitative study design was carried out using 341 nurses working in selected hospitals in Addis Ababa from January 2012 to May 2012. Systematic random sampling was the method employed to select two governmental and two non-governmental hospitals. The researchers used triangulation in their study method making use of: Frommelt’s Attitude Toward Care of the Dying (FATCOD) Scale, Palliative Care Quiz for Nursing (PCQN) and practice questions. This led to enhanced validity of the data. EPI-INFO and SPSS software statistical packages were applied for data entry and analysis. Result Of the total 365 nurses selected, a response rate of 341 (94.2%) were registered. Out of the total study participants, 104 (30.5%) had good knowledge and 259 (76%) had favorable attitude towards PC. Medical and surgical wards as well as training on PC were positively associated with knowledge of nurses. Institution, individuals’ level of education, working in medical ward and the training they took part on PC were also significantly associated with the attitude the nurses had. Nurses working in Hayat Hospital (nongovernmental) had a 71.5% chance of having unfavorable attitude towards PC than those working in Black Lion Hospital (governmental). Regarding their knowledge aspect of practice, the majority of the respondents 260 (76.2%) had poor implementation, and nearly half of the respondents had reported that the diagnosis of patients was usually performed at the terminal stage. In line with this, spiritual and medical conditions were highly taken into consideration while dealing with terminally ill patients. Conclusion The nurses had poor knowledge and knowledge aspect

    Human Immunodeficiency Virus (HIV) and intestinal parasitic infections are among the main health problems in developing countries like Ethiopia. Particularly, co-infections of these diseases would worsen the progression of HIV to Acquired Immunodeficiency Syndrome (AIDS). The purpose of this study was to determine the magnitude and risk factors for intestinal parasites in relation to HIV infection and immune status. The study was conducted in (1) HIV positive on antiretroviral therapy (ART) and (2) ART naïve HIV positive patients, and (3) HIV-negative individuals, at All African Leprosy and Tuberculosis (TB) Eradication and Rehabilitation Training Center (ALERT) hospital in Addis Ababa, Ethiopia. Study participants were interviewed using structured questionnaires to obtain socio-demographic characteristics and assess risk factors associated with intestinal parasitic infection. Intestinal parasites were identified from fecal samples by direct wet mount, formol ether concentration, and modified Ziehl-Neelsen staining techniques. The immune status was assessed by measuring whole blood CD4 T-cell count. The overall magnitude of intestinal parasite was 35.08%. This proportion was different among study groups with 39.2% (69/176), 38.83% (40/103) and 27.14% (38/140) in ART naïve HIV positives patients, in HIV negatives, and in HIV positive on ART patients respectively. HIV positive patients on ART had significantly lower magnitude of intestinal parasitic infection compared to HIV negative individuals. Intestinal helminths were significantly lower in HIV positive on ART and ART naïve patients than HIV negatives. Low monthly income, and being married, divorced or widowed were among the socio-demographic characteristics associated with intestinal parasitic infection. No association was observed between the magnitude of intestinal parasites and CD4 T-cell count. However, Cryptosporidium parvum, and Isospora belli were exclusively identified in individuals with CD4 T

    Background HIV patients on antiretroviral therapy have shown elevated incidence of dyslipidemia, lipodystrophy, and cardiovascular disease (CVD). Most studies, however, focus on cohorts from developed countries, with less data available for these co-morbidities in Ethiopia and sub-Saharan Africa. Methods Adult HIV-negative (n = 36), treatment naïve (n = 51), efavirenz (EFV)-treated (n = 91), nevirapine (NVP)-treated (n = 95), or ritonavir-boosted lopinavir (LPV/r)-treated (n=44) subjects were recruited from Black Lion Hospital in Addis Ababa, Ethiopia. Aortic pressure, augmentation pressure, and pulse wave velocity (PWV) were measured via applanation tonometry and carotid intima-media thickness (cIMT) and carotid arterial stiffness, and brachial artery flow-mediated dilation (FMD) were measured via non-invasive ultrasound. Body mass index, waist-to-hip circumference ratio (WHR), skinfold thickness, and self-reported fat redistribution were used to quantify lipodystrophy. CD4+ cell count, plasma HIV RNA levels, fasting glucose, total-, HDL-, and LDL-cholesterol, triglycerides, hsCRP, sVCAM-1, sICAM-1, leptin and complete blood count were measured. Results PWV and normalized cIMT were elevate and FMD impaired in EFV- and LPV/r-treated subjects compared to NVP-treated subjects; normalized cIMT was also elevated and FMD impaired in the EFV- and LPV/r-treated subjects compared to treatment-naïve subjects. cIMT was not statistically different across groups. Treated subjects exhibited elevated markers of dyslipidemia, inflammation, and lipodystrophy. PWV was associated with age, current EFV and LPV/r used, heart rate, blood pressure, triglycerides, LDL, and hsCRP, FMD with age, HIV duration, WHR, and glucose, and cIMT with age, current EFV use, skinfold thickness, and blood pressure. Conclusions Current EFV- or LPV/r-treatment, but not NVP-treatment, correlated with elevated markers of atherosclerosis, which may involve mechanisms distinct from traditional risk factors

    Background Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is the most dramatic epidemic of the century that has claimed over two decades more than 3 million deaths. Sub-Saharan Africa is heavily affected and accounts for nearly 70% of all cases. Mother-to-child transmission of HIV is responsible for 20% of all HIV transmissions. With no preventive interventions, 50% of HIV infections are transmitted from HIV-positive mothers to newborns. HIV-testing is central to prevent vertical transmission. Despite, awareness campaigns, prevention measures, and more recently, promotion of antiviral regimens, the prevalence of cases and deaths is still rising and the prevalence of prevention of mother-to-child transmission (PMTCT) voluntary counseling test (VCT) use remains low. This study identifies predictors and possible barriers of HIV-testing among antenatal care attendees based on the health belief model (HBM) in Addis Ababa, Ethiopia. Methods The study was an institution-based cross-sectional survey conducted from September 1 to September 30, 2013. A total of 308 individuals were interviewed using structured questionnaires adopted and modified from similar studies. Data were collected through face-to-face interviews. A logistic regression was used to identify factors associated with HIV-test use. Results In spite of satisfactory knowledge on HIV/AIDS transmission, participants are still at high risk of contracting the infection, wherein only 51.8% tested for HIV; among the married, only 84.1% and among the gestational age of third trimester, 34.1% mothers tested for HIV. Based on the HBM, failure to use PMTCT-HIV-test was related to its perceived lack of net benefit (adjusted odds ratio [AOR] =0.34, confidence interval [CI] [0.19–0.58], P<0.001), but interviewees with high perceived self-efficacy were 1.9 times more likely to use HIV-test (AOR =1.90, CI [1.09–3.33], P<0.05). Conclusion and recommendation This study identifies perceived

    Background Intestinal parasites (IPs) are major concerns in most developing countries where HIV/AIDS cases are concentrated and almost 80% of AIDS patients die of AIDS-related infections. In the absence of highly active antiretroviral therapy (HAART), HIV/AIDS patients in developing countries unfortunately continue to suffer from the consequences of opportunistic and other intestinal parasites. The aim of the study was to determine the prevalence of intestinal parasites in relation to CD4+ T cells levels and anemia among HAART initiated and HAART naïve pediatric HIV patients in a Model ART center in Addis Ababa, Ethiopia. Methods A prospective comparative cross-sectional study was conducted among HAART initiated and HAART naive pediatric HIV/AIDS patients attending a model ART center at Zewditu Memorial Hospital between August 05, 2013 and November 25, 2013. A total of 180 (79 HAART initiated and 101 HAART naïve) children were included by using consecutive sampling. Stool specimen was collected and processed using direct wet mount, formol-ether concentration and modified Ziehl-Neelsen staining techniques. A structured questionnaire was used to collect data on socio-demographic and associated risk factors. CD4+ T cells and complete blood counts were performed using BD FACScalibur and Cell-Dyn 1800, respectively. The data was analyzed by SPSS version 16 software. Logistic regressions were applied to assess any association between explanatory factors and outcome variables. P values < 0.05 were taken as statistically significant. Results The overall prevalence of IPs was 37.8% where 27.8% of HAART initiated and 45.5% of HAART naive pediatric HIV/AIDS patients were infected (p < 0.05). Cryptosporidium species, E. histolytica/dispar, Hook worm and Taenia species were IPs associated with CD4+ T cell counts <350 cells/μμL in HAART naive patients. The overall prevalence of anemia was 10% in HAART and 31.7% in non-HAART groups. Hook worm, S. stercoralis and H. nana were

    Street children worldwide do not have the information, skills, health services, and support they need to go through sexual development during adolescence. This study is undertaken to systematically investigate the fit between street children's sexual and reproductive health needs and the existing services. A cross-sectional study was conducted among 422 street children and four service providers. About 72.5% of the respondents were sexually active during data collection and 84.3% of males and 85.7% of females tended to have multiple sexual partners. More than two-thirds (67.3%) of the participants had used at least one type of substance. History of substance use (OR = 2.5; 95% CI = 1.42–4.56) and being on the street for the first one to three years (OR = 5.9; 95% CI = 1.41–7.22) increased the likelihood of having sexual activity. More than half (64.9%) of the street children did not attend any kind of sexual or reproductive health education programs. Lack of information on available services (26.5%) was the biggest barrier for utilization of local sexual and reproductive health services. From the individual interview with coordinator, the financial and networking problems were hindering the service delivery for street children. In conclusion, street children who are special high risk group have not been targeted and hence continue to remain vulnerable and lacking in sexual and reproductive health services and sexual health services are poorly advertised and delivered to them.

    Background Managing blood stream infection in Africa is hampered by lack of bacteriological support needed for antimicrobial stewardship, and background data needed for empirical treatment. A combined pro- and retrospective approach was used to overcome thresholds in clinical research in Africa. Methods Outcome and characteristics including age, HIV infection, pancytopenia and bacteriological results were studied in 292 adult patients with two or more SIRS criteria using univariate and confirming multivariate logistic regression models. Expected randomly distributed resistance covariation was compared with observed co-resistance among gram-negative enteric bacteria in 92 paediatric blood culture isolates that had been harvested in the same hospital during the same period of time. Results Mortality was fivefold increased among patients with positive blood culture results [50.0% vs. 9.8%; OR 11.24 (4.38–25.88), p < 0.0001], and for this group of patients mortality was significantly associated with antimicrobial resistance [OR 23.28 (3.3–164.4), p = 0.002]. All 11 patients with Enterobacteriaceae resistant to 3rd. generation cephalosporins died. Eighty-nine patients had pancytopenia grade 3–4. Among patients with negative blood culture results, mortality was significantly associated with pancytopenia [OR 3.12 (1.32–7.39), p = 0.01]. HIV positivity was not associated with increased mortality. Antimicrobial resistance that concerned gram-negative enteric bacteria, regardless of species, was characterized by co-resistance between third generation cephalosporins, gentamicin, chloramphenicol, and co-trimoxazole. Conclusion Mortality was strongly associated with growth of bacteria resistant to empirical treatment, and these patients were dead or dying when bacteriological reports arrived. Because of co-resistance, alternative efficient antibiotics would not have been available in Ethiopia for 8/11 Enterobacteriaceae-infected patients with isolates resistant to third generation cephalosporins. Strong and significant resistance covariation between 3rd. generation cephalosporins, chloramphenicol, gentamicin, and co-trimoxazole was identified. Pronounced pancytopenia was common and associated with increased mortality. HIV positive patients had no excess mortality. PMID:26670718

    Research on obstetric fistula has paid limited attention to the lived experiences of survivors. This qualitative study explored the evolution of survivors' perceptions of their social relationships and health since developing this obstetric complication. In-depth interviews were conducted with eight survivors who were selected based on purposive and snowball sampling techniques. Thematic categorization and content analysis was used to analyze the data. The resultant themes included participants' understanding of factors predisposing to fistula, challenges they encounter, their coping responses, and the meaning of their experiences. First, the participants had a common understanding of the factors that predisposed them to obstetric fistula. They mentioned poor knowledge about pregnancy, early marriage, cultural practices, and a delay in or lack of access to emergency obstetric care. Second, the participants suffered from powerlessness experienced during their childhood and married lives. They also faced prolonged obstructed labor, physical injury, emotional breakdown, depression, erosion of social capital, and loss of healthy years. Third, to control their negative emotions, participants reported isolating themselves, having suicidal thoughts, positive interpretation about the future, and avoidance. To obtain relief from their disease, the women used their family support, sold their properties, and oriented to reality. Fourth, the participants were struggling to keep going, to accept their changed reality, and to change their perspectives on life. In conclusion, obstetric fistula has significant physical, psychosocial, and emotional consequences. The study participants were not passive victims but rather active survivors of these challenges. Adequate support was not provided by their formal or informal support systems. To prevent and manage obstetric fistula successfully, there should be family-based interventions that improve access to and provision of emergency obstetric care. These initiatives should also ensure men's participation, women's empowerment, and the utilization of community-based institutions. PMID:25525395

  11. Effectiveness of a multimodal hand hygiene campaign and obstacles to success in Addis Ababa, Ethiopia

    2014-01-01

    Background Hand hygiene is the cornerstone of infection control and reduces rates of healthcare associated infection. There are limited data evaluating hand hygiene adherence and hand hygiene campaign effect in resource-limited settings, especially in Sub-Saharan Africa. This study assessed the impact of implementing a World Health Organization (WHO)-recommended multimodal hand hygiene campaign at a hospital in Ethiopia. Methods This study included a before-and-after assessment of health care worker (HCW) adherence with WHO hand hygiene guidelines. It was implemented in three phases: 1) baseline evaluation of hand hygiene adherence and hospital infrastructure; 2) intervention (distribution of commercial hand sanitizer and implementation of an abbreviated WHO-recommended multimodal hand hygiene campaign); and 3) post-intervention evaluation of HCW hand hygiene adherence. HCWs’ perceptions of the campaign and hand sanitizer tolerability were assessed through a survey performed in the post-intervention period. Results At baseline, hand washing materials were infrequently available, with only 20% of sinks having hand-washing materials. There was a significant increase in hand hygiene adherence among HCWs following implementation of a WHO multimodal hand hygiene program. Adherence increased from 2.1% at baseline (21 hand hygiene actions/1000 opportunities for hand hygiene) to 12.7% (127 hand hygiene actions /1000 opportunities for hand hygiene) after the implementation of the hand hygiene campaign (OR = 6.8, 95% CI 4.2-10.9). Hand hygiene rates significantly increased among all HCW types except attending physicians. Independent predictors of HCW hand hygiene compliance included performing hand hygiene in the post-intervention period (aOR = 5.7, 95% CI 3.5-9.3), in the emergency department (aOR = 4.9, 95% CI 2.8-8.6), during patient care that did not involve Attending Physician Rounds (aOR = 2.4, 95% CI 1.2-4.5), and after patient contact (aOR = 2.1, 95% CI 1.4-3.3). In the perceptions survey, 64.0% of HCWs indicated preference for commercially manufactured hand sanitizer and 71.4% indicated their hand hygiene adherence would improve with commercial hand sanitizer. Conclusions There was a significant increase in hand hygiene adherence among Ethiopian HCWs following the implementation of a WHO-recommended multimodal hand hygiene campaign. Dissatisfaction with the current WHO-formulation for hand sanitizer was identified as a barrier to hand hygiene adherence in our setting. PMID:24636693

    This study was performed during two weeks among 86 paediatric outpatients of poor socio-economic background. A control group comprised 60 healthy children. Enterotoxigenic Escherichia coli (ETEC) was the most common diarrhoeal agent isolated (26%). Strains of ETEC producing heat-labile (LT) only or LT and heat-stable (ST) enterotoxin were isolated from 11% each and ETEC producing ST only from 4% of the patients. ETEC was also found not infrequently among controls (10%). ETEC with O-antigens 78, 6 and 8 were shown to harbour colonization factors. Enterotoxigenic bacteria were found as contaminants in 5 of 24 feeding bottles investigated. Enteropathogenic Escherichia coli (EPEC) and Shigella species were isolated from 8% each and rotavirus from 24% of the patients. Twelve patients infected with ETEC only were compared to 66 patients not infected with ETEC. Patients infected with ETEC had a relatively mild disease and it was not possible by clinical findings to distinguish those patients infected with ETEC, LT and/or ST producing, carrying or not carrying colonization factors from those infected with other agents. This study underlines the need for extended studies of the clinical significance of ETEC infection in developing countries. PMID:6753473

    Background. The Akaki River in Ethiopia has been found to contain elevated levels of several metals. Our objectives were to characterize metals exposures of residents living near the Akaki River and to assess metal levels in their drinking water. Methods. In 2011, we conducted a cross-sectional study of 101 households in Akaki-Kality subcity (near the Akaki River) and 50 households in Yeka subcity (distant to the Akaki River). One willing adult in each household provided urine, blood, and drinking water sample. Results. Urinary molybdenum (p < 0.001), tungsten (p < 0.001), lead (p < 0.001), uranium (p < 0.001), and mercury (p = 0.049) were higher in Akaki-Kality participants compared to Yeka participants. Participants in both subcities had low urinary iodine; 45% met the World Health Organization (WHO) classification for being at risk of moderate iodine deficiency. In Yeka, 47% of households exceeded the WHO aesthetic-based reference value for manganese; in Akaki-Kality, only 2% of households exceeded this value (p < 0.001). There was no correlation between metals levels in water samples and clinical specimens. Conclusions. Most of the exposures found during this investigation seem unlikely to cause acute health effects based on known toxic thresholds. However, toxicity data for many of these metals are very limited.

    Background. Dermatophytosis is common worldwide and continues to increase. Objective. This study was undertaken to determine the prevalence of dermatophytosis and the spectrum of ringworm fungi in patients attending a tertiary hospital. Methods. Samples were collected from 305 patients. A portion of each sample was examined microscopically and the remaining portion of each sample was cultured onto plates of Sabouraud's dextrose agar containing chloramphenicol with and without cycloheximide. Dermatophyte isolates were identified by studying macroscopic and microscopic characteristics of their colonies. Result. Of 305 samples, fungi were detected in 166 (54.4%) by KOH of which 95 were dermatophytes while 242 (79.4%) samples were culture positive of which 130 isolates were dermatophytes. Among dermatophyte isolates T. violaceum was the most common (37.7%) cause of infection. Tinea unguium was the predominant clinical manifestation accounting for 51.1% of the cases. Patients with age group 25-44 and 45-64 years were more affected. T. violaceum was the most common pathogen in tinea unguium and tinea capitis, whereas T. mentagrophytes was the most common pathogen in tinea pedis. Conclusion. Further intensive epidemiological studies of ring worm fungus induced dermatophytosis which have public health significance are needed. PMID:26448763

    Background Blood stream infections are major cause of morbidity and mortality in children in developing countries. The emerging of causative agents and resistance to various antimicrobial agents are increased from time to time. The main aim of this study was to determine the bacterial agents and antimicrobial susceptibility patterns among children suspected of having septicemia. Methods A cross sectional study involved about 201 pediatric patients (≤ 12 years) was conducted from October 2011 to February 2012 at pediatric units of TikurAnbessa Specialized Hospital and Yekatit 12 Hospital. Standard procedure was followed for blood sample collection, isolate identifications and antimicrobial susceptibility testing. Results Among 201 study subjects 110 (54.7%) were males. Majority 147 (73.1%) of them were neonates (≤ 28 days). The mean length of hospital stay before sampling was 4.29 days. Out of the 201 tested blood samples, blood cultures were positive in 56 (27.9%).Gram negative and Gram positive bacteria constituted 29(51.8%) and 26(46.4%), respectively. The most frequent pathogen found was Staphylococcus aureus 13 (23.2%), followed by Serratia marcescens 12(21.4%), CoNS 11(19.6%), klebsiella spp 9(16%) and Salmonella spp 3(5.4%). Majority of bacterial isolates showed high resistance to Ampicillin, Penicillin, Co-trimoxazole, Gentamicin and Tetracycline which commonly used in the study area. Conclusion Majority of the isolates were multidrug resistant. These higher percentages of multi-drug resistant emerged isolates urge us to take infection prevention measures and to conduct other large studies for appropriate empiric antibiotic choice.

    Coordination of different business activities among units becomes vital as organizations pay much attention to their core activities. Thus, their fruitfulness constantly relies on their capacity to coordinate their internal and external activities in the supply chain outside their own boundaries. Giving consideration to these obvious reasons, this paper aims to investigate the determinants of supply chain coordination of milk and dairy industries. The data were collected from 330 milk suppliers, processors, and retailers in the central part of Ethiopia. The structural equation modeling has been employed to develop the structural relationship between key constructs and measured variables. In total, 15 measured variables for coordination in the supply chain have been identified. These are further grouped into four factors namely, non-price coordination, price coordination, relationships and product development decision. It has been observed that the implementation of these factors could maximize the coordination linkage among supply chain members. Thus, dairy sectors should take the identified coordination factors into account in each of their business dealings. PMID:26405618

    Background Drug-resistant TB has emerged as a major challenge facing TB prevention and control efforts. In Ethiopia, the extent/trend of drug resistance TB is not well known. The aim of this study was to determine the pattern and trend of resistance to first line anti-TB drugs among culture positive retreatment cases at St.Peter’s TB Specialized Hospital. Findings A hospital based retrospective study was used to assess the pattern of anti-TB drug resistance among previously treated TB patients referred to St.Peter’s TB Specialized Hospital from January 2004-December 2008 Gregorian calendar(GC) for better diagnosis and treatment. Among 376 culture positive for M. tuberculosis one hundred and two (27.1%) were susceptible to all of the four first line anti-TB drugs -Isoniazid (INH), Rifampicin (RIF), Ethambutol (ETB) & Streptomycin (STM). While 274 (72.9%) were resistant to at least one drug. Any resistance to STM (67.3%) was found to be the most common and the prevalence of MDR-TB was 174 (46.3%). Trend in resistance rate among re-treatment cases from 2004 to 2008 showed a significant increase for any drug as well as for INH, RIF, and MDR resistance (P <0.05 for trend). Conclusions There has been an increasing trend in drug resistance in recent years, particularly in retreatment cases. Therefore, establishing advanced diagnostic facilities for early detection of MDR-TB and expanding second line treatment center to treat MDR-TB patients and to prevent its transmission is recommended.

    Librarians are increasingly placed in the role of instructor and are required to design and deliver effective instruction. This article highlights ADDIE, an instructional design model that librarians at Weill Cornell Medical College used to redesign an evidence-based medicine course taken by first-year medical students. The ADDIE model incorporates the five phases of analysis, design, development, implementation, and evaluation. It was found that the application of ADDIE can result in instruction that focuses on learning outcomes relevant to students, meets students' needs, and facilitates active learning.

  6. Global Megacities Differing Adaptation Responses to Climate Change: an Analysis of Annual Spend of Ten Major cities on the adaptation economy

    Urban areas are increasingly at risk from climate change with negative impacts predicted for human health, the economy and ecosystems. These risks require responses from cities, to improve the resilience of their infrastructure, economy and environment to climate change. Policymakers need to understand what is already being spent on adaptation so that they can make more effective and comprehensive adaptation plans. Through the measurement of spend in the newly defined 'Adaptation Economy' we analysis the current efforts of 10 global megacities in adapting to climate change. These cities were chosen based on their size, geographical location and their developmental status. The cities are London, Paris, New York, Mexico City, Sao Paulo, Beijing, Mumbai, Jakarta, Lagos and Addis Ababa. It is important to study a range of cities in different regions of the world, with different climates and at different states of socio-economic development. While in economic terms, disaster losses from weather, climate and geophysical events are greater in developed countries, fatalities and economic losses as a proportion of GDP are higher in developing countries. In all cities examined the Adaptation Economy is still a small part of the overall economy accounting for a maximum of 0.3% of the Cities total GDP (GDPc). The differences in total spend are significant between cities in developed and rapidly emerging countries, compared to those in developing countries with a spend ranging from £16 million to £1,500 million. Comparing key sub sectors, we demonstrate that there are distinctive adaptation profiles with developing cities having a higher relative spend on health, while developed cities have a higher spend on disaster preparedness, ICT and professional services. Comparing spend per capita and as a percentage of GDPc demonstrates even more clearly disparities between the cities in the study; developing country cities spend half as much as a proportion of GPCc in some cases, and

    CLUVA (CLimate change and Urban Vulnerability in Africa; http://www.cluva.eu/) is a 3 years project, funded by the European Commission in 2010. The main objective of CLUVA is to develop context-centered methods and knowledge to be applied to African cities to assess vulnerabilities and increase knowledge on managing climate related risks. The project estimates the impacts of climate changes in the next 40 years at urban scale and downscales IPCC climate projections to evaluate specific threats to selected African test cities. These are mainly from floods, sea-level rise, droughts, heat waves, and desertification. The project evaluates and links: social vulnerability; urban green structures and ecosystem services; urban-rural interfaces; vulnerability of urban built environment and lifelines; and related institutional and governance dimensions of adaptation. The multi-scale and multi-disciplinary qualitative, quantitative and probabilistic approach of CLUVA is currently being applied to selected African test cities (Addis Ababa - Ethiopia; Dar es Salaam - Tanzania; Douala - Cameroun; Ouagadougou - Burkina Faso; St. Louis - Senegal). In particular, the poster will present preliminary findings for the Dar es Salaam case study. Dar es Salaam, which is Tanzania's largest coastal city, is exposed to floods, coastal erosion, droughts and heat waves, and highly vulnerable to impacts as a result of ineffective urban planning (about 70% unplanned settlements), poverty and lack of basic infrastructure (e.g. lack of or poor quality storm water drainage systems). Climate change could exacerbate the current situation increasing hazard-exposure alongside the impacts of development pressures which act to increase urban vulnerability for example because of informal (unregulated) urbanization. The CLUVA research team - composed of climate and environmental scientists, risk management experts, urban planners and social scientists from both European and African institutions - has

    2014-01-01

    Background High maternal mortality is a continued challenge for the achievement of the fifth millennium development goal in Sub-Saharan African countries including Ethiopia. Although institutional delivery service utilization ensures safe birth and a key to reduce maternal mortality, interventions at the community and/or institutions were unsatisfactorily reduced maternal mortality. Institutional delivery service utilization is affected by the interaction of personal, socio-cultural, behavioral and institutional factors. Therefore this study was designed to assess factors associated with institutional delivery service use among mothers in Bahir Dar city administration. Methods A community based cross sectional study was conducted in Bahir Dar City administration Northwest of Addis Ababa, Ethiopia. Four hundred eighty four mothers were included in the study. Data were collected by trained female data collectors. Descriptive statistics, binary and multivariable logistic regression analyses were computed. Statistical significance was considered at p < 0.05 and the strength of statistical association was assessed by odds ratios (OR) with 95% confidence intervals. Result In this study, 78.8% of women gave birth to their current child at health institution. The multivariable logistic regression showed that, attending primary education (AOR = 4.7[95% CI:1.3-16.7], secondary education (AOR = 3.5[95% CI:1.1-10.7]), age at first marriage; first time marriage at 15–19 years (AOR = 5.4[95% CI:2.0-15.0]) and first time marriage at 20–24 years (AOR = 5.0[95% CI:1.5-16.8] and gestational age at first ANC visit (first trimester) (AOR = 5.3[1.3-22.2]) and second trimester (AOR = 2.8[95% CI:0.7-11.]) were independent factors affecting institutional delivery service utilization. Conclusion In this study, institutional delivery service utilization is optimal, urban mothers were more likely to practice institutional delivery. This study indicated that

    PubMed

    Blagg, Christopher R

    2009-01-01

    Thomas Addis is an important figure in the history of nephrology. Born in Scotland and trained in Edinburgh, he came to San Francisco in 1911 to the new Stanford School of Medicine to run the clinical laboratory. Over the next 38 years, he made many contributions to renal physiology, the investigation of the structure and function of the kidneys in Bright's disease, and studies of kidney growth, hypertrophy and protein metabolism. Largely forgotten today, he was one of the first to use urea clearance as a measure of kidney function and was the first to systematize examination of the urinary sediment - the Addis count. He was also a leader in the use of diet and rest in the treatment of Bright's disease. Unknown to most nephrologists, before he came to the United States during the first 6 years following his graduation, he became one of the leading clinical investigators in hematology. His special interests were the mechanism of blood clotting and hemophilia. He was the first to transfuse fresh blood into a hemophiliac patient and show that this shortened the patient's clotting time. Addis was a great, if eccentric, personality as well as a great scientist. He was beloved by his many colleagues and students and was honored in his lifetime both in the United States and Great Britain.

  19. Patient-based continuum of care in nephrology: why read Thomas Addis' "Glomerular Nephritis" in 2010?

    PubMed

    Piccoli, Giorgina B

    2010-01-01

    The name of Thomas Addis (1881-1949) is linked to several aspects of nephrological practice: from the "Addis count" of urinary elements, to the history of diet in chronic kidney diseases. He was accustomed to working with limited funds, and developed his theories with relatively simple means, combined with the careful, long-term observation of single cases. His political ideas were progressive; his outlook on life was optimistic. This is deeply reflected in his Glomerular Nephritis: Diagnosis and Treatment, a book worth reading in the era of chronic kidney disease (CKD), as it contains sharp analyses of the organizational aspects, and accurate comments on the role of the physician - all subjects of interest for the present times and challenges. One of Addis' ingenious ideas was to follow his patients throughout their lifelong disease, thus anticipating the theories of continuum of care and of therapeutic alliance between patients and physicians. He used to tailor his prescriptions and frequency of controls to each patient and phase of the disease, thus anticipating the tailored therapies and the patient empowerment presently considered as fundamental in chronic diseases. Furthermore, he suggested that physicians should work outside the hospital in small coordinated teams, in which volunteers, dietitians and laboratory technicians would play a crucial role. Patient-centered care and the importance of nonmedical team members are clear from the first lines of his book. As far as we know, he was the first physician to stress the role of volunteers in CKD, anticipating by decades nonprofit organizations such as the National Kidney Foundation.

  3. Reflections on the development of psychology in Ethiopia and future directions.

    The introduction and development of psychology in Ethiopia has been mainly limited to Addis Ababa University in the capital city, and also to educational and school psychology which was highly influenced by the field of education at this pioneering university. Similarly, mental health services have been principally developed at the Amanuel Mental Hospital in Addis Ababa that has existed since the 1950s. However, the expansion of higher learning institutions on one hand, and the apparent growing prevalence of mental illness on the other, seem to have contributed to the development of both mental health training and services in other regional cities and towns. Although the influence of the education-oriented psychological training of the Addis Ababa University is still present, clinical psychology education and services are now being started in other universities. One of these is the master's programme in clinical psychology opened for the first time in the University of Gondar. This article sheds light on the development of psychology in Ethiopia and addresses some of the issues raised about the factors that have influenced its development such as traditional beliefs, poverty and comparisons between mental health in lower middle-income countries and higher middle-income countries ( Uppal et al., 2014 ). The paper also proposes future directions for the education, research, infrastructure and services of clinical psychology and mental health in Ethiopia.

Applying the above-mentioned procedure, taking into account all available information on the inundation profiles for various zones within the basin, leads to a probability distribution for the TWI threshold value. In the next step, the urban residential hot spots to flooding are delineated in the GIS environment by overlaying the map of TWI and the UMT units classified as residential for various percentiles of the TWI threshold. Differences in exposure characteristics can be assessed for a range of different residential types, including for example between condominium/multi-storey, single storey stone/concrete and areas predominantly associated with mud/wood construction. For each percentile value considered, the delineated flood-prone residential areas and the number of people potentially affected to flooding are calculated. Moreover, the potential dependence of the estimated threshold percentiles on the flooding return period is investigated. As a demonstration, the urban residential hotspots to flooding are delineated for 16th, 50th and 84th percentiles of the TWI value for the cities of Dar es Salaam and Addis Ababa.

    Bayesian framework enables the probabilistic characterization of the threshold value by calculating the complementary probability of false delineation of flood prone zones as a function of various threshold values. For a given return period, the probability of false delineation is calculated as the sum of the probability of indicating a zone flood prone which is not indicated as such by the inundation profile and the probability that a zone is indicated as not flood prone but indicated as flood prone by the inundation profile. Applying the above-mentioned procedure, taking into account all available information on the inundation profiles for various zones within the basin, leads to a probability distribution for the TWI threshold value. In the next step, the urban residential hot spots to flooding are delineated in the GIS environment by overlaying the map of TWI and the UMT units classified as residential for various percentiles of the TWI threshold.

    Addis was born and educated in Edinburgh, from the University of which he graduated MB in 1905, and MD in 1908, in which year he also gained membership of Edinburgh's Royal College of Physicians. After researching disordered haemostasis associated with various clinical conditions, he spent over a year in Germany: in Berlin with Dr. E.L. Salkowski learning urinalysis and at Heidelberg under Ludolph von Krehl studying haemophilics. Back in Edinburgh he concluded that the ultimate cause of haemophilia was an 'anatomical defect in the molecule of prothrombin'. He was the first to monitor the effects on plasma clotting times of transfusion of anticoagulated blood into a haemophilic. In 1911 he was recruited by Ray Lyman Wilbur, the first dean of the Stanford University School of Medicine, to investigate metabolic disorders including jaundice, diabetes and ultimately chronic renal disease.

    Addis was born and educated in Edinburgh, from the University of which he graduated MB in 1905, and MD in 1908, in which year he also gained membership of Edinburgh's Royal College of Physicians. After researching disordered haemostasis associated with various clinical conditions, he spent over a year in Germany: in Berlin with Dr. E.L. Salkowski learning urinalysis and at Heidelberg under Ludolph von Krehl studying haemophilics. Back in Edinburgh he concluded that the ultimate cause of haemophilia was an 'anatomical defect in the molecule of prothrombin'. He was the first to monitor the effects on plasma clotting times of transfusion of anticoagulated blood into a haemophilic. In 1911 he was recruited by Ray Lyman Wilbur, the first dean of the Stanford University School of Medicine, to investigate metabolic disorders including jaundice, diabetes and ultimately chronic renal disease. In 1917 he described the 'urea ratio'--the mathematical and conceptual forerunner of clearance formulae--and over the next 30 years developed a combined clinical and laboratory service for patients with inexorably failing kidneys. He devised an effective, rational and individually based dietary treatment--some patients such as Linus Pauling, who presented in 1941 with marked nephrosis, responded completely.

    The Addi-Chek (filtration; Millipore Corp., Bedford, Mass.) and BACTEC (radiometric detection of growth in culture media; Johnston Laboratories, Inc., Towson, Md.) systems were compared with the 10-ml culture (centrifugation) method for the recovery of microorganisms from peritoneal dialysate collected from patients with clinical evidence of peritonitis and containing greater than or equal to 200 leukocytes per mm3. Both alternate methods were comparable, and results were not significantly different from those of the conventional 10-ml culture method. All systems were adversely affected in their capacity to recover organisms when dialysates had been collected during periods of antimicrobial therapy. PMID:3517053

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

    Salt Lake City, Utah, will host the 2002 Winter Olympic Games. The city is located on the southeastern shore of the Great Salt Lake and sits to the west of the Wasatch Mountains, which rise more than 3,500 meters (10,000 feet) above sea level. The city was first settled in 1847 by pioneers seeking relief from religious persecution. Today Salt Lake City, the capital of Utah, is home to more than 170,000 residents. This true-color image of Salt Lake City was acquired by the Enhanced Thematic Mapper Plus (ETM+), flying aboard Landsat 7, on May 26, 2000. The southeastern tip of the Great Salt Lake is visible in the upper left of the image. The furrowed green and brown landscape running north-south is a portion of the Wasatch Mountains, some of which are snow-capped (white pixels). The greyish pixels in the center of the image show the developed areas of the city. A number of water reservoirs can be seen east of the mountain range. Salt Lake City International Airport is visible on the northwestern edge of the city. About 20 miles south of the airport is the Bingham Canyon Copper Mine (tan pixels), the world's largest open pit excavation. See also this MODIS image of Utah.

  17. Inequality and City Size*

    Baum-Snow, Nathaniel; Pavan, Ronni

    2013-01-01

    Between 1979 and 2007 a strong positive monotonic relationship between wage inequality and city size has developed. This paper investigates the links between this emergent city size inequality premium and the contemporaneous nationwide increase in wage inequality. After controlling for the skill composition of the workforce across cities of different sizes, we show that at least 23 percent of the overall increase in the variance of log hourly wages in the United States from 1979 to 2007 is explained by the more rapid growth in the variance of log wages in larger locations relative to smaller locations. This influence occurred throughout the wage distribution and was most prevalent during the 1990s. More rapid growth in within skill group inequality in larger cities has been by far the most important force driving these city size specific patterns in the data. Differences in the industrial composition of cities of different sizes explain up to one-third of this city size effect. These results suggest an important role for agglomeration economies in generating changes in the wage structure during the study period. PMID:24954958

    Great cities connect people; failed cities isolate people. Despite the fundamental importance of physical, face-to-face social ties in the functioning of cities, these connectivity networks are not explicitly observed in their entirety. Attempts at estimating them often rely on unrealistic over-simplifications such as the assumption of spatial homogeneity. Here we propose a mathematical model of human interactions in terms of a local strategy of maximizing the number of beneficial connections attainable under the constraint of limited individual travelling-time budgets. By incorporating census and openly available online multi-modal transport data, we are able to characterize the connectivity of geometrically and topologically complex cities. Beyond providing a candidate measure of greatness, this model allows one to quantify and assess the impact of transport developments, population growth, and other infrastructure and demographic changes on a city. Supported by validations of gross domestic product and human immunodeficiency virus infection rates across US metropolitan areas, we illustrate the effect of changes in local and city-wide connectivities by considering the economic impact of two contemporary inter- and intra-city transport developments in the UK: High Speed 2 and London Crossrail. This derivation of the model suggests that the scaling of different urban indicators with population size has an explicitly mechanistic origin. PMID:26179988

    Club theoretical analysis of migration between asymmetrical cities shows that centralised policy intervention is necessary to ensure the efficient allocation of people between cities. Administrative and economic measures are compared as policy instruments of central government. These instruments are found to differ in their effects on residential allocation and welfare. In particular, a lump-sum tax-transfer programme pools the welfare-creating potentials of cities, thus affecting the efficiency condition. Therefore, lump-sum tax-transfers are superior to both quantity rationing and Pigouvian taxes, and they also activate, rather than stabilise, migration. PMID:21584984

    Growth in 'mega-cities' is altering the landscape and the atmosphere in such a way as to curtail normal photosynthesis. By using data from The Defense Meteorological Satellite Program's Operational Linescan System, researchers have been able to look at urban sprawl by monitoring the emission of light from cities at night. By overlaying these 'light maps' onto other data such as soil and vegetation maps, the research shows that urbanization can have a variable but measurable impact on photosynthetic productivity.

    This paper presents the biocorrosion of city sewer collectors impregnated with special polymer sulphur binders, polymerized sulphur, which is applied as the industrial waste material. The city sewer collectors are settled with a colony of soil bacteria which have corrosive effects on its structure. Chemoautotrophic nitrifying bacteria utilize the residues of halites (carbamide) which migrate in the city sewer collectors, due to the damaged dampproofing of the roadway and produce nitrogen salts. Chemoorganotrophic bacteria utilize the traces of organic substrates and produce a number of organic acids (formic, acetic, propionic, citric, oxalic and other). The activity of microorganisms so enables the origination of primary and secondary salts which affect physical properties of concretes in city sewer collectors unfavourably.

    The urban population has surpassed 50% in the Maghreb: first in Tunisia, followed by Algeria and Morocco. This phenomenon has greatly affected the distribution of power and the forms of its exercise in the political, social, and economic domain. The old city social strata are becoming extinct while city management is falling more and more under the control of cadres originally from rural areas. Urbanization is occurring at a slower pace than in other developing countries, however. In Morocco, the small- and medium-sized towns are growing at a faster rate than the cities. Their lack of infrastructure and services, like those that exist in the periphery of large cities, preoccupies the small- and medium-sized towns. The urban explosion is much more contained than its management is adapting. Legal and illegal housing will dominate the Moroccan city in the future. In the last decade, Moroccan authorities have tried to establish mechanisms to integrate populations in slums and illegal housing with the urban space. The Tunisians are also working on this. In Algeria, the rigid, urban formal management leaves no room to develop any type of housing. The problem of housing is even more grave here than the other 2 countries. Structural adjustment policies promote selling rather than renting houses. The government is not involved in social and health services. Algeria has a 2-tier society: a minority involved in the private sector and the majority who depends on the collapsing public sector which cannot meet the great needs of the poor. Persons with college degrees are unemployed in Algeria. One no longer knows how to build towns with the traditional medinas. The transportation system is falling apart in cities. Cities dump liquid and solid wastes directly into the sea or the wadis. The major risk of maghrebian cities lies in socioeconomic inequalities.

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. A major cause for severe land subsidence is excessive groundwater extraction related to rapid urbanization and population growth. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs for (infra)structure. The total damage worldwide is estimated at billions of dollars annually. As subsidence is often spatially variable and can be caused by multiple processes, an assessment of subsidence in delta cities needs to answer questions such as: what are the main causes? What is the current subsidence rate and what are future scenarios (and interaction with other major environmental issues)? Where are the vulnerable areas? What are the impacts and risks? How can adverse impacts be mitigated or compensated for? Who is involved and responsible to act? In this study a quick-assessment of subsidence is performed on the following mega-cities: Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok. Results of these case studies will be presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

    In many coastal cities land subsidence now exceeds absolute sea level rise up to a factor of ten. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will continue to sink, even below sea level. The ever increasing industrial and domestic demand for water in these cities results in excessive groundwater extraction, causing severe subsidence. In addition, coastal cities are often faced with larger natural subsidence, as they are built on thick sequences of soft soil. The impacts of subsidence are further exacerbated by climate-induced sea level rise. Land subsidence results in two types damage: foremost it increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. Secondly, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs of roads and transportation networks, sewage systems, buildings and foundations. The total damage worldwide is estimated at billions of dollars annually. To survey the extent of groundwater associated subsidence, we conducted a quick-assessment of subsidence in a series of mega-cities (Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok). For each city research questions included: what are the main causes, how much is the current subsidence rate and what are predictions, where are the vulnerable areas, what are the impacts and risks, how can adverse impacts can be mitigated or compensated for, and what governmental bodies are involved and responsible to act? Using the assessment, this paper discusses subsidence modelling and measurement results from the selected cities. The focus is on the importance of delayed settlement after increases in hydraulic heads, the role of the subsurface composition for subsidence rates and best practice solutions for subsiding cities. For the latter, urban (ground)water management, adaptive flood risk management

    Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

  10. Earth's City Lights

    This image of Earth's city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth's surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region. Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya. The Earth Observatory article Bright Lights, Big City describes how NASA scientists use city light data to map urbanization. Image by Craig Mayhew and Robert Simmon, NASA GSFC, based on DMSP data

    Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in individual cities, but an integrated evaluation of emissions and population exposure is still lacking. Our analysis suggests that the average exposure to outdoor UFPs in Asian cities is about four-times larger than that in European cities but impacts on human health are largely unknown. This article reviews some fundamental drivers of UFP emissions and dispersion, and highlights unresolved challenges, as well as recommendations to ensure sustainable urban development whilst minimising any possible adverse health impacts.

    Nicholas Clapp, a filmmaker and archeology enthusiast, had accumulated extensive information concerning Ubar, the fabled lost city of ancient Arabia. When he was unable to identify its exact location, however, he turned to the Jet Propulsion Laboratory (JPL) for assistance in applying orbital remote sensing techniques. JPL scientists searched NASA's shuttle imaging radar, as well as Landsat and SPOT images and discovered ancient caravan tracks. This enabled them to prepare a map of the trails, which converged at a place known as Ash Shisr. An expedition was formed, which found structures and artifacts from a city that predates previous area civilization by a thousand years. Although it will take time to validate the city as Ubar, the discovery is a monumental archeological triumph.

    The literature views many African cities as dysfunctional with a hodgepodge of land uses and poor "connectivity." One driver of inefficient land uses is construction decisions for highly durable buildings made under weak institutions. In a novel approach, we model the dynamics of urban land use with both formal and slum dwellings and ongoing urban redevelopment to higher building heights in the formal sector as a city grows. We analyze the evolution of Nairobi using a unique high-spatial resolution data set. The analysis suggests insufficient building volume through most of the city and large slum areas with low housing volumes near the center, where corrupted institutions deter conversion to formal sector usage.

  15. Reproducing in cities.

    PubMed

    Mace, Ruth

    2008-02-01

    Reproducing in cities has always been costly, leading to lower fertility (that is, lower birth rates) in urban than in rural areas. Historically, although cities provided job opportunities, initially residents incurred the penalty of higher infant mortality, but as mortality rates fell at the end of the 19th century, European birth rates began to plummet. Fertility decline in Africa only started recently and has been dramatic in some cities. Here it is argued that both historical and evolutionary demographers are interpreting fertility declines across the globe in terms of the relative costs of child rearing, which increase to allow children to outcompete their peers. Now largely free from the fear of early death, postindustrial societies may create an environment that generates runaway parental investment, which will continue to drive fertility ever lower.

    Mexico City is located in a valley at high elevation (2,268 m) and is subject to atmospheric inversion related problems similar to those found in Denver, Colorado. In addition, Mexico City has a tropical climate (latitude 19{degrees} 25 minutes N), and therefore has more sunlight available for production of photochemical smog. There are approximately 9.5 million people spread in a 1,500 km{sup 2} (25 sq. mi) urban area, and more than two million automobiles (D.G.P.T. 1979) which use leaded gasoline. Furthermore, Mexico City is the principal industrial center in the country with more than 131,000 industries. The growth of the city has led to a serious air pollution problem, and there is concern over the possible pollutant effects on human health. The authors discuss work done to characterize the chemical composition of the aerosol. It is shown that many of the organic compounds which have been detected in urban aerosols are carcinogens.

    In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs. This effects roads and transportation networks, hydraulic infrastructure - such as river embankments, sluice gates, flood barriers and pumping stations -, sewage systems, buildings and foundations. The total damage worldwide is estimated at billions of dollars annually. Excessive groundwater extraction after rapid urbanization and population growth is the main cause of severe land subsidence. In addition, coastal cities are often faced with larger natural subsidence, as they are built on thick sequences of soft soil. Because of ongoing urbanization and population growth in delta areas, in particular in coastal megacities, there is, and will be, more economic development in subsidence-prone areas. The impacts of subsidence are further exacerbated by extreme weather events (short term) and rising sea levels (long term).Consequently, detrimental impacts will increase in the near future, making it necessary to address subsidence related problems now. Subsidence is an issue that involves many policy fields, complex technical aspects and governance embedment. There is a need for an integrated approach in order to manage subsidence and to develop appropriate strategies and measures that are effective and efficient on both the short and long term. Urban (ground)water management, adaptive flood risk management and related spatial planning strategies are just examples of the options available. A major rethink is needed to deal with the 'hidden' but urgent

  16. Asthma in inner cities.

    LeNoir, M. A.

    1999-01-01

    While the management of asthma has improved over the past two decades, the incidence of asthma in the inner city has not. The inner city, comprising a disproportionate number of people who live close to or below the poverty line, shows increased rates of morbidity and mortality from asthma. African Americans and Hispanic Americans are two to six times more likely to die from asthma than their white counterparts. When federally funded programs have targeted reducing morbidity and mortality in children from these populations, they have succeeded, but in a national study only 18 states had initiatives targeting asthma in low-income populations. This is tantamount to a public health crisis. Patients are not always properly diagnosed and are often without a regular source of health care, and symptoms are seen only in an acute context. Living conditions for the inner-city child have significant allergen triggers associated with house dust, cockroaches, cigarette smoke, chemical pollutants, and particulate matter. Viral infections, such as those caused by respiratory syncytial virus, are worse in crowded living conditions. The desirability of an increased public awareness of the seriousness of the disease and the need for chronic health care are issues that should be raised, through culturally relevant public means and in the knowledge that visual information is most effective. Physicians must understand the proper use of rescue and controller drugs, and asthma education must expand beyond doctors and nurses in their offices. The National Medical Association is committed to doing this aggressively, and community organizations, alliances, and coalitions must also aggressively follow. Public agencies must be lobbied to set high standards for proper asthma care and resources. With organizations acting in concert, the mortality and morbidity from asthma can be substantially prevented in the inner city. PMID:12653387

    Cities are characterized by concentrating population, economic activity and services. However, not all cities are equal and a natural hierarchy at local, regional or global scales spontaneously emerges. In this work, we introduce a method to quantify city influence using geolocated tweets to characterize human mobility. Rome and Paris appear consistently as the cities attracting most diverse visitors. The ratio between locals and non-local visitors turns out to be fundamental for a city to truly be global. Focusing only on urban residents' mobility flows, a city-to-city network can be constructed. This network allows us to analyse centrality measures at different scales. New York and London play a central role on the global scale, while urban rankings suffer substantial changes if the focus is set at a regional level. PMID:26179991

    Healthy Ageing is an important focus of the European Healthy Cities Network and has been supported by WHO since 2003 as a key strategic topic, since 2010 in cooperation with the Global Network of Age-friendly Cities and Communities. Based on the methodology of realist evaluation, this article synthesizes qualitative evidence from 33 structured case studies (CS) from 32 WHO European Healthy Cities, 72 annual reports from Network cities and 71 quantitative responses to a General Evaluation Questionnaire. City cases are assigned to three clusters containing the eight domains of an age-friendly city proposed by WHO's Global Age-friendly City Guide published in 2007. The analysis of city's practice and efforts in this article takes stock of how cities have developed the institutional prerequisites and processes necessary for implementing age-friendly strategies, programmes and projects. A content analysis of the CS maps activities across age-friendly domains and illustrates how cities contribute to improving the social and physical environments of older people and enhance the health and social services provided by municipalities and their partners.

    We study how urban quality evolves as a result of carbon dioxide emissions as urban agglomerations grow. We employ a bottom-up approach combining two unprecedented microscopic data on population and carbon dioxide emissions in the continental US. We first aggregate settlements that are close to each other into cities using the City Clustering Algorithm (CCA) defining cities beyond the administrative boundaries. Then, we use data on CO2 emissions at a fine geographic scale to determine the total emissions of each city. We find a superlinear scaling behavior, expressed by a power-law, between CO2 emissions and city population with average allometric exponent β = 1.46 across all cities in the US. This result suggests that the high productivity of large cities is done at the expense of a proportionally larger amount of emissions compared to small cities. Furthermore, our results are substantially different from those obtained by the standard administrative definition of cities, i.e. Metropolitan Statistical Area (MSA). Specifically, MSAs display isometric scaling emissions and we argue that this discrepancy is due to the overestimation of MSA areas. The results suggest that allometric studies based on administrative boundaries to define cities may suffer from endogeneity bias. PMID:24577263

  4. Securing water for the cities.

    PubMed

    Satterthwaite, D

    1993-01-01

    Many cities in developing countries have grown so much that they can no longer provide adequate, sustainable water. Over pumping in Dakar and Mexico City has forced those cities to obtain water from ever more distant sources. In Dakar, the result has been saltwater intrusion. Overpumping has caused Mexico City to sink, in some areas by as much as 9 m, resulting in serious damage to buildings and sewage and drainage pipes. Other cities facing similar water problems are coastal cities in Peru (e.g., Lima), La Rioja and Catamarca in Argentina, cities in Northern Mexico, and cities in dry areas of Africa. For some cities, the problem is not so much ever more distant water supplies but insufficient funds to expand supplies. Bangkok and Jakarta both face saltwater intrusion into their overdrawn aquifers. Even through agriculture is the dominant user of water in most countries, demand concentrated in a small area exhausts local and regional sources and pollutes rivers, lakes, and coasts with untreated human and industrial waste. Most cities in Africa and Asia do not have a sewerage system. Further, most cities do not have the drains to deal with storm water and external floodwater, causing frequent, seasonal flooding. The resulting stagnant water provides breeding grounds for insect vectors of diseases (e.g., malaria). The problems in most cities are a result of poor management, not lack of water. Reducing leaks in existing piped distribution systems from the usual 60% loss of water to leaks to 12% would increase the available water 2-fold. Another way to address water shortages would be commercial, industrial, and recreational use of minimally treated waste water, such as is the case in Madras and Mexico City. Political solutions are needed to resolve inadequate water supply and waste management.

  5. CityGML - Interoperable semantic 3D city models

    2012-07-01

    CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research.

The evaluation of the land management practices in these cities is in terms of the current realities and the possibility for the acceptability of new, exotic but deemed sustainable urban land management styles. Noted strongly in this current discourse is that Africa is a region with varied of contexts requiring a critical assessment of issues before policy strategies are implemented in terms of land tenure, land administration corruption, political will and receptivity of the so-called foreign philosophies in urban land governance. The study recommends relevant training of the land and planning experts in Africa. In addition, there is general need to balance between 'place prosperity' with 'people prosperity' as they relate to land management noting that space and capital make the difference in sustainable human habitats' creation and management.

    Cities can be characterized and modelled through different urban measures. Consistency within these observables is crucial in order to advance towards a science of cities. Bettencourt et al. have proposed that many of these urban measures can be predicted through universal scaling laws. We develop a framework to consistently define cities, using commuting to work and population density thresholds, and construct thousands of realizations of systems of cities with different boundaries for England and Wales. These serve as a laboratory for the scaling analysis of a large set of urban indicators. The analysis shows that population size alone does not provide us enough information to describe or predict the state of a city as previously proposed, indicating that the expected scaling laws are not corroborated. We found that most urban indicators scale linearly with city size, regardless of the definition of the urban boundaries. However, when nonlinear correlations are present, the exponent fluctuates considerably. PMID:25411405

  8. The dynamics of city formation*

    2013-01-01

    This paper examines city formation in a country whose urban population is growing steadily over time, with new cities required to accommodate this growth. In contrast to most of the literature there is immobility of housing and urban infrastructure, and investment in these assets is taken on the basis of forward-looking behavior. In the presence of these fixed assets cities form sequentially, without the population swings in existing cities that arise in current models, but with swings in house rents. Equilibrium city size, absent government, may be larger or smaller than is efficient, depending on how urban externalities vary with population. Efficient formation of cities with internalization of externalities involves local government intervention and borrowing to finance development. The paper explores the institutions required for successful local government intervention. PMID:25089087

    This highly detailed view of the City of Paris 49.0N, 0.0E) shows a varied land use pattern in great detail. Several airports are clearly seen such as the two major international airports of Orly and Le Bourget. Paris was founded in pre-Roman times on an island in the Seine River and continued as a Roman outpost. The easily defensible location was one of the keys to growth. Other factors include easy access by river and the productive hinterland.

  10. Digging the city

    SciTech Connect

    Paulson, S.L.

    1996-02-01

    For city dwellers and commuters, major construction and repair projects by underground utilities have traditionally meant torn-up streets, detours, snarled traffic, flaring tempers and other urban headaches. For store and business owners, utility projects also have frequently been harmful to the bottom line. Customer parking often is curtailed and deliveries are missed because of street excavations, and business hours may even have to be cut because of interruptions in utility service. But natural gas utilities in major cities across the country are working hard to change that reality. Their effort has two major focuses: community-relations programs that anticipate problems and ease tensions between the utility and local residents and business owners, and new technologies that drastically limit the amount of excavation that needs to be done in repairing or replacing gas distribution lines. The paper describes a case study in the community-relations side of the equation which involved a recent project by Pacific Gas and Electric Co. (PG and E) in the congested streets of San Francisco`s famed Chinatown.

    Here we sketch the rudiments of what constitutes a smart city which we define as a city in which ICT is merged with traditional infrastructures, coordinated and integrated using new digital technologies. We first sketch our vision defining seven goals which concern: developing a new understanding of urban problems; effective and feasible ways to coordinate urban technologies; models and methods for using urban data across spatial and temporal scales; developing new technologies for communication and dissemination; developing new forms of urban governance and organisation; defining critical problems relating to cities, transport, and energy; and identifying risk, uncertainty, and hazards in the smart city. To this, we add six research challenges: to relate the infrastructure of smart cities to their operational functioning and planning through management, control and optimisation; to explore the notion of the city as a laboratory for innovation; to provide portfolios of urban simulation which inform future designs; to develop technologies that ensure equity, fairness and realise a better quality of city life; to develop technologies that ensure informed participation and create shared knowledge for democratic city governance; and to ensure greater and more effective mobility and access to opportunities for urban populations. We begin by defining the state of the art, explaining the science of smart cities. We define six scenarios based on new cities badging themselves as smart, older cities regenerating themselves as smart, the development of science parks, tech cities, and technopoles focused on high technologies, the development of urban services using contemporary ICT, the use of ICT to develop new urban intelligence functions, and the development of online and mobile forms of participation. Seven project areas are then proposed: Integrated Databases for the Smart City, Sensing, Networking and the Impact of New Social Media, Modelling Network Performance

    2001-01-01

    The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This simulated natural color image presents a late spring view of north central Utah that includes all of the Olympic sites. The image extends from Ogden in the north, to Provo in the south; and includes the snow-capped Wasatch Mountains and the eastern part of the Great Salt Lake.

    This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution

    This article considers the development of educating cities from a political perspective, illustrating in detail the diversity of organisations and individuals involved and the challenges they are facing. Bearing in mind that educating cities were established from the 1990s onwards in Europe and spread to other continents from there, the purpose of this article is to demonstrate how this proposal was adopted in Latin America. After discussing the basic aims of educating cities, the paper focuses on the Latin American experience, giving examples of existing projects within the educating cities initiative. The authors are particularly interested in the contrast between the political intentions of educating cities on the one hand and the social, economic, political and cultural world on the other hand. They observe that in this context there is a danger of the individual being forgotten, which contradicts the actual intention of the educating city concept. They also discuss the problem of who should carry out the realisation of educating cities and how the various stakeholders might coordinate their actions. Contemplating new directions at the end of their paper, the authors sum up a number of guidelines and offer recommendations for action in developing educating cities.

This paper will consider the application of the heavens to the organisation of the ‘Cosmic State’, the human polity modelled on the assumption of a close relationship between society on the one hand and planetary and stellar patterns on the other. I will also examine the foundation of Baghdad within the tradition of celestial town planning and argue that the city may be seen as a ‘talisman’, designed to connect heaven to Earth and ensure peace, stability and political success by harmonising time and space.

    This paper raises the question of whether or not the virtues of big city size were exaggerated in the literature which appeared in the 1970s with respect to developing country megacities. It examines negative externalities (especially pollution), the capital costs associated with megacity growth, the productivity advantages of large cities, the role of spatial restructuring towards a policentric pattern as a relief to core city congestion, and the problems of metropolitan management (including the appropriate institutional framework). The adoption of constructive policy actions could handle the following problems: that the declining rates of megacity growth may reflect declining productivity advantages; that capital costs of urbanization increase strongly with city size; that there are diseconomies of scale in urban management; that negative externalities may be more severe in developing country megacities in physical but not in imputed monetary damage terms; and that policentric evolution may be hampered by the wrong type of government intervention.

    Recent studies have revealed the importance of centrality measures to analyze various spatial factors affecting human life in cities. Here we show how it is possible to extract the backbone of a city by deriving spanning trees based on edge betweenness and edge information. By using as sample cases the cities of Bologna and San Francisco, we show how the obtained trees are radically different from those based on edge lengths, and allow an extended comprehension of the “skeleton” of most important routes that so much affects pedestrian/vehicular flows, retail commerce vitality, land-use separation, urban crime and collective dynamical behaviours.

  15. Network Structure and City Size

    Levinson, David

    2012-01-01

    Network structure varies across cities. This variation may yield important knowledge about how the internal structure of the city affects its performance. This paper systematically compares a set of surface transportation network structure variables (connectivity, hierarchy, circuity, treeness, entropy, accessibility) across the 50 largest metropolitan areas in the United States. A set of scaling parameters are discovered to show how network size and structure vary with city size. These results suggest that larger cities are physically more inter-connected. Hypotheses are presented as to why this might obtain. This paper then consistently measures and ranks access to jobs across 50 US metropolitan areas. It uses that accessibility measure, along with network structure variables and city size to help explain journey-to-work time and auto mode share in those cities. A 1 percent increase in accessibility reduces average metropolitan commute times by about 90 seconds each way. A 1 percent increase in network connectivity reduces commute time by 0.1 percent. A 1 percent increase in accessibility results in a 0.0575 percent drop in auto mode share, while a 1 percent increase in treeness reduces auto mode share by 0.061 percent. Use of accessibility and network structure measures is important for planning and evaluating the performance of network investments and land use changes. PMID:22253764

  18. Studies of Total Electron Content variations at low-latitude stations within the Equatorial Ionization Anomaly zone

    NASA Astrophysics Data System (ADS)

    Lilian, Olatunbosun

    2016-07-01

    The total electron content (TEC) is an important parameter to monitor for possible space weather impacts. The radio waves that pass through the earth's ionosphere travel more slowly than their free space velocity due to group path delay of the ionosphere. This group path delay is directly proportional to the TEC of the ionosphere. Using dual frequency GPS receiver at low latitude stations of Ile-Ife (7.52oN, 4.28oE), Addis Ababa (9.04oN, 38.77oE) and Bangalore (13.03oE, 77.57oE), all located within 0 - 15oN of the equatorial anomaly region, the measurement of ionospheric TEC for 2012 has been carried out. The data from the three stations were used to study the diurnal, monthly and seasonal variations of TEC. The diurnal variations maximize between 10:00 - 16:00UT, 08:00 - 14:00UT and 06:00 - 12:00UT for Ile-Ife, Addis Ababa and Bangalore stations respectively. The diurnal variations showed wave-like pertubation during disturbed and quiet periods at Bangalore and Addis Ababa stations. The monthly average TEC variations showed that the month of March recorded the highest TEC value of ~59TECu at about 16:00UT in Ile-Ife station, while TEC at Addis Ababa and Bangalore maximize in October with ~72TECu and 65TECu at about 11:00UT and 09:00UT respectively. Seasonal variations showed that TEC maximizes during the equinoctial months and least in summer, over the three stations.

    Access to safe and reliable drinking water is vital for a healthy population. However, surface water may be contaminated with pesticides because of the nearby agricultural areas as well as from household application. Water samples were collected from water sources in Jimma zone and Addis Ababa, Ethiopia. The extraction and clean up of the samples were undertaken using liquid-solid and liquid-liquid methods. Human exposure was assessed by calculating the estimated daily intake (EDI) of pesticides in water and compared with the acceptable daily intake (ADI) and the acute reference dose (ARfD). The mean concentrations of 2,4-D, malathion, diazinon and fenpropimorph were 1.59-13.90 μg/l and 0.11-138 µg/l in Jimma and Addis Ababa water sources, respectively. The residue level of some of the pesticides were above the European drinking water guide line values, which is an indication of an illegal use of pesticides in the study areas. Concerning human health risk estimation, there was no acute risk (EDI < ARfD). However, chronic risks to human health were observed from exposure to diazinon and fenpropimorph (EDI > ADI) for Jimma and Addis Ababa populations, respectively. A comprehensive monitoring is required to reduce the level of pesticide residues in the water and to minimize particularly the long term human health risks. PMID:27501312

    2014-01-01

    Material management faces a dual challenge: on the one hand satisfying large and increasing demands for goods and on the other hand accommodating wastes and emissions in sinks. Hence, the characterization of material flows and stocks is relevant for both improving resource efficiency and environmental protection. This article focuses on the urban scale, a dimension rarely investigated in past metal flow studies. We compare the copper (Cu) metabolism of two cities in different economic states, namely, Vienna (Europe) and Taipei (Asia). Substance flow analysis is used to calculate urban Cu balances in a comprehensive and transparent form. The main difference between Cu in the two cities appears to be the stock: Vienna seems close to saturation with 180 kilograms per capita (kg/cap) and a growth rate of 2% per year. In contrast, the Taipei stock of 30 kg/cap grows rapidly by 26% per year. Even though most Cu is recycled in both cities, bottom ash from municipal solid waste incineration represents an unused Cu potential accounting for 1% to 5% of annual demand. Nonpoint emissions are predominant; up to 50% of the loadings into the sewer system are from nonpoint sources. The results of this research are instrumental for the design of the Cu metabolism in each city. The outcomes serve as a base for identification and recovery of recyclables as well as for directing nonrecyclables to appropriate sinks, avoiding sensitive environmental pathways. The methodology applied is well suited for city benchmarking if sufficient data are available. PMID:25866460

  2. Prioritizing obesity in the city.

    2012-02-01

    A decade ago, the World Health Organization declared obesity to be a global epidemic. Accordingly, there is a growing body of research examining how "obesogenic environments" contribute to the increasing prevalence of obesity. Using the ANGELO Framework, this research explores the role of municipal policies and practices in constructing obesogenic environments in two Southern Ontario cities in order to examine how socio-cultural and political environments shape excess body weight. Data was collected from municipal policy documents, public health websites, and key informants in Hamilton and Mississauga, Ontario, Canada. Results indicate that while the cities took different approaches to dealing with obesity, they both reflected the cities' overall prioritizing of health. Additionally, the findings reveal the pervasiveness of values and attitudes held in the socio-cultural environment in further shaping (and being shaped by) political as well as economic and physical environments in the cities. The importance of explicitly acknowledging the official discourse of the city, which this study demonstrates to be a significant factor in constructing obesogenic environments, is highlighted. Theoretical contributions and policy implications are also discussed.

    2016-04-01

    Pollen are emitted in the atmosphere both in the country-side and in cities. Yet the majority of the population is exposed to pollen in cities. Allergic reactions may be induced by short-term exposure to pollen. This raises the question how variable pollen concentration in cities are in temporally and spatially, and how much of the pollen in cities are actually produced in the urban region itself. We built a high resolution (1 × 1 km) pollen dispersion model based on WRF-Chem to study a city's pollen budget and the spatial and temporal variability in concentration. It shows that the concentrations are highly variable, as a result of source distribution, wind direction and boundary layer mixing, as well as the release rate as a function of temperature, turbulence intensity and humidity. Hay Fever Forecasts based on such high resolution emission and physical dispersion modelling surpass traditional hay fever warning methods based on temperature sum methods. The model gives new insights in concentration variability, personal and community level exposure and prevention. The model will be developped into a new forecast tool to serve allergic people to minimize their exposure and reduce nuisance, coast of medication and sick leave. This is an innovative approach in hay fever warning systems.

This project was to update the efficiency and capacity of current hydro production due to increased water flow demands that could pass through existing generation facilities. During 2006-2012, this project completed efficiency evaluation as it related to its main objective by completing a feasibility study, undergoing necessary City Council approvals and required federal environmental reviews. As a result of Phase 1 of the project, a feasibility study was conducted to determine feasibility of hydro and solar portions of the original proposal. The results indicated that the existing Hydro plant which was constructed in the 1960’s was running at approximately 77% efficiency or less. Brigham City proposes that the efficiency calculations be refined to determine the economic feasibility of improving or replacing the existing equipment with new high efficiency equipment design specifically for the site. Brigham City completed the Feasibility Assessment of this project, and determined that the Upper Hydro that supplies the main culinary water to the city was feasible to continue with. Brigham City Council provided their approval of feasibility assessment’s results. The Upper Hydro Project include removal of the existing powerhouse equipment and controls and demolition of a section of concrete encased penstock, replacement of penstock just upstream of the turbine inlet, turbine bypass, turbine shut-off and bypass valves, turbine and generator package, control equipment, assembly, start-up, commissioning, Supervisory Control And Data Acquisition (SCADA), and the replacement of a section of conductors to the step-up transformer. Brigham City increased the existing 575 KW turbine and generator with an 825 KW turbine and generator. Following the results of the feasibility assessment Brigham City pursued required environmental reviews with the DOE and

  5. City planning as preventive medicine.

    The health and well-being of rapidly growing urban populations is a global health issue. Cities in the global north and south are faced with rising health inequities - or avoidable differences in health determinants and outcomes based on place, social status and ethnicity. This commentary suggests that focusing only on treatment interventions in cities is likely to fail because populations will be forced to go back into the urban living and working conditions that likely made them sick in the first place. City planning as preventive medicine includes taking a relational and systems approach to urban health, requiring health assessments for all urban policy making, promoting neighborhood health centers as engines of community economic development and gathering place-based health indicator data to track progress and adapt interventions over time as conditions change.

    This paper assesses policy development in, with and for Healthy Cities in the European Region of the World Health Organization. Materials for the assessment were sourced through case studies, a questionnaire and statistical databases. They were compiled in a realist synthesis methodology, applying theory-based evaluation principles. Non-response analyses were applied to ascertain the degree of representatives of the high response rates for the entire network of Healthy Cities in Europe. Further measures of reliability and validity were applied, and it was found that our material was indicative of the entire network. European Healthy Cities are successful in developing local health policy across many sectors within and outside government. They were also successful in addressing 'wicked' problems around equity, governance and participation in themes such as Healthy Urban Planning. It appears that strong local leadership for policy change is driven by international collaboration and the stewardship of the World Health Organization. The processes enacted by WHO, structuring membership of the Healthy City Network (designation) and the guidance on particular themes, are identified as being important for the success of local policy development.

    The concept of sustainability has been an integral part of development work since the late 1970s. Sustainability is no longer a buzzword but a reality that must be addressed by cities all over the world. Increasing empirical evidence indicates that city sustainability is not just related to technical issues, such as carbon emissions, energy consumption and waste management, or on the economic aspects of urban regeneration and growth, but also it covers social well-being of different groups living within increasingly cosmopolitan towns and cities. Heritage is seen as a major component of quality of life, features that give a city its unique character and provide the sense of belonging that lies at the core of cultural identity. In other words, heritage by providing important social and psychological benefits enrich human life with meanings and emotions, and raise quality of life as a key component of sustainability. The purpose of this paper, therefore, is to examine the role that built cultural heritage can play within sustainable urban development.

    1992-01-01

    Phase 3 of Project WISH saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the E-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystem constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS. Spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System) for mass minimization. A structural dynamic analysis of the optimal structure also conducted using ASTROS enabled a study of the modes, frequencies, displacements, and accelerations of the E-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

  1. Ground-Penetrating Radar (GPR) Examination at the Fanta Stream Site, Central Ethiopia

    NASA Astrophysics Data System (ADS)

    Lanzarone, P. M.

    2009-12-01

    The use of near-surface geophysical analysis for paleontological and archaeological site detection has been a relatively unexplored field in sub-Saharan Africa. A new site discovered in 2007 within the city limits of Addis Ababa, Ethiopia is currently under imminent destruction due to urban and industrial entrenchment. Located along the banks of the Fanta Stream, this site contains visible exposures of dense in-situ fossiliferous deposits and archaeological remains. The Fanta Stream Site is important because of the widespread deposition of fossil deposits possibly dating to the early or middle Pleistocene epoch from a rare high altitude context of the east African region. A detailed GPR survey over a large study area (> 1000 m2) utilizing a GSSI SIR-2 with 100 and 500 MHz antennas provides a multi-scalar data visualization of fossil bearing stratigraphic units and information about the vertical and lateral distribution of these deposits across the site. The GPR profiles exhibit strong radar reflections at the contact zones between sedimentary units known to contain fossil and artifactual deposits. Shallow (< 3 m) hand-augured geological cores along GPR transects provide a correlative ground truth for the depth and extent of primary deposits across the site. These geophysical data situate the known and associated fossil and artifact assemblages into their appropriate spatial and geoenvironmental contexts and this information will be useful for developing a regional natural and cultural resource management plan for the Fanta Site.

    Based on a study of anonymized GPS probe vehicle traces measured by personal navigation devices in vehicles randomly distributed in city traffic, empirical synchronized flow in oversaturated city traffic has been revealed. It turns out that real oversaturated city traffic resulting from speed breakdown in a city in most cases can be considered random spatiotemporal alternations between sequences of moving queues and synchronized flow patterns in which the moving queues do not occur.

  16. Characteristics of cities with rapid transit

    Siregar, F.M.

    1991-01-01

    This study identifies the characteristics of cities and urban areas associated with rapid transit systems as part of the urban multimodal transportation system. This is addressed by studying the characteristics of global cities that have utilized rapid transit (100 cities in 1986) and a global sample of cities that have not (100 cities). Data are collected on eighteen variables which include population size, growth rate, density of the central city and metropolitan area, automobile registrations per 1,000 population, city bus riderships, existence of a tramway system in the city, number of large banks located in the city, the country's economy, and whether it is a capital city. The research found that two of the most important city characteristics associated with rapid transit utilization are city population size and level of automobile ownership. The larger the population size and the higher the number of automobiles per 1,000 population, the greater the occurrence of rapid-transit systems. Also, rapid transit systems world wide are growing in number, and the largest growth of rapid transit ridership is being generated by rapid transit systems in developing countries.

  20. Project WISH: The Emerald City

    NASA Technical Reports Server (NTRS)

    1991-01-01

    Project WISH (Wandering Interplanetary Space Harbor) is a three-year design effort currently being conducted at The Ohio State University. Its goal is the design of a space oasis to be used in the exploration of the solar system during the midtwenty-first century. This spacecraft, named Emerald City, is to conduct and provide support for missions to other planetary bodies with the purpose of exploration, scientific study, and colonization. It is to sustain a crew of between 500 and 1000 people at a time, and be capable of traveling from a nominal orbit to the planets in reasonably short flight times. Such a ship obviously presents many technical and design challenges, some of which were examined through the course of Project WISH. This year, Phase 2 (1990-1991) of Project WISH was carried out. The basic design of the Emerald City resulting from Phase 1 (1989-1990) was taken and improved upon through more detailed analysis and revision. At the core of this year's study were orbital mechanics, propulsion, attitude control, and human factors. Throughout the year, these areas were examined and information was compiled on their technologies, performances, and relationships. Then, using the data obtained through these studies, two specific missions were designed: an envelope mission from a nominal orbit of 4 AU to Saturn and a single point design for a specific mission from the Earth to Mars. The latter was designed in view of the special interest that Mars is attracting for near-future space exploration. The mission to Saturn has all the first six planets within its flight envelope in less than or equal to a 3-year flight time at any time upon demand, and it has Uranus in its flight envelope most of the time upon demand. These mission studies provided data on the approximate size, weight, number of engines, and other important design values that would be required for the Emerald City.

Funded by DOE, the six-station network provided 5-minute averaged measurements of direct normal, global, and diffuse horizontal solar irradiance. The data were processed at NREL to improve the assessment of the solar radiation resources in the southeastern United States. Historical HBCU data available online include quality assessed 5-min data, monthly reports, and plots. In January 1997 the HBCU sites became part of the CONFRRM solar monitoring network and data from the two remaining active stations, Bluefield State College and Elizabeth City State University, are collected by the NREL Measurement & Instrumentation Data Center (MIDC).

  6. Uncertainties in city greenhouse gas inventories

    Wattenbach, Martin; Redweik, Richard; Luedtke, Stefan; Deng-Beck, Chang; Ross, Lutz; Nagel, Claus

    2015-04-01

    In 1993 mayors from 50 cities in 20 countries gathered at the UN in New York under the umbrella of the International Council for Local Environmental Initiatives (ICLEI) to issue a declaration aimed at cutting carbon dioxide emissions from cities. By today 465 cities report their GHG emissions in ICLEIs carbonn Cities Climate Registry (cCR) . Many cities worldwide are on the route to implement the combined new standard for city-based GHG accounting and reporting, named the Global Protocol for Community-Scale GHG Emissions (GPC). These extensive data sources offer the unique chance to better understand, manage and reduce city GHG emissions. However, many cities are already reporting or have reported their GHG emission in non GPC conform tools. This heterogeneous data source raises the question on how these data could be potentially transferred to a GPC conform level. For the transfer process it is very important to understand and quantify the potential losses of information and increase or decrease in uncertainty due to class conversions and associated recalculations of GHG data. Here we compare existing GHG reports from different sources based on the use of different tools. We look at data from the carbonn Registry by ICLEI, the CDP, C40 and the Ecoregion tool. Using examples of existing data form cities in Europe we demonstrate potential information losses and inconsistencies leading to increased uncertainty. We also illustrate the potential mapping schemes for the data structures and identify uncertainties from using alternative mappings. In conclusion it is essential to develop consistent data structures in order to allow the use of city GHG data for time series analysis and city intercomparison.

  7. Low-carbon infrastructure strategies for cities

    NASA Astrophysics Data System (ADS)

    Kennedy, C. A.; Ibrahim, N.; Hoornweg, D.

    2014-05-01

    Reducing greenhouse gas emissions to avert potentially disastrous global climate change requires substantial redevelopment of infrastructure systems. Cities are recognized as key actors for leading such climate change mitigation efforts. We have studied the greenhouse gas inventories and underlying characteristics of 22 global cities. These cities differ in terms of their climates, income, levels of industrial activity, urban form and existing carbon intensity of electricity supply. Here we show how these differences in city characteristics lead to wide variations in the type of strategies that can be used for reducing emissions. Cities experiencing greater than ~1,500 heating degree days (below an 18 °C base), for example, will review building construction and retrofitting for cold climates. Electrification of infrastructure technologies is effective for cities where the carbon intensity of the grid is lower than ~600 tCO2e GWh-1 whereas transportation strategies will differ between low urban density (<~6,000 persons km-2) and high urban density (>~6,000 persons km-2) cities. As nation states negotiate targets and develop policies for reducing greenhouse gas emissions, attention to the specific characteristics of their cities will broaden and improve their suite of options. Beyond carbon pricing, markets and taxation, governments may develop policies and target spending towards low-carbon urban infrastructure.

  12. Urban Scaling of Cities in the Netherlands

    van Raan, Anthony F. J.; van der Meulen, Gerwin; Goedhart, Willem

    2016-01-01

    We investigated the socioeconomic scaling behavior of all cities with more than 50,000 inhabitants in the Netherlands and found significant superlinear scaling of the gross urban product with population size. Of these cities, 22 major cities have urban agglomerations and urban areas defined by the Netherlands Central Bureau of Statistics. For these major cities we investigated the superlinear scaling for three separate modalities: the cities defined as municipalities, their urban agglomerations and their urban areas. We find superlinearity with power-law exponents of around 1.15. But remarkably, both types of agglomerations underperform if we compare for the same size of population an agglomeration with a city as a municipality. In other words, an urban system as one formal municipality performs better as compared to an urban agglomeration with the same population size. This effect is larger for the second type of agglomerations, the urban areas. We think this finding has important implications for urban policy, in particular municipal reorganizations. A residual analysis suggests that cities with a municipal reorganization recently and in the past decades have a higher probability to perform better than cities without municipal restructuring.

    The CIVITAS (Virtual Cities with Technologies for Learning and Simulating) project presents a research, teaching and extension approach directed to the construction of cities imagined by students in the first years of elementary school, with an emphasis to the fourth grade. The teacher ventures on a deviation from the official curriculum proposed to reflect upon the invention of cities along with the children. Within this context, the game Città is introduced as an environment that allows the creation of digital real/virtual/imagined cities, and enables different forms of interaction among the students through networked computers. The cooperative situations, made possible by the access to the game, are tools for teachers and students to think about the information that operate as general rules and words of order with the invention of the city/knowledge.

    1996-01-01

    Some problems posed by the rapid urbanization of the developing world are reviewed. The author suggests that the fate of these rapidly growing cities will determine the fate of both nations and regions. He notes that rather than continuing to swell the megacities, such as Mexico City, recent demographic trends have been favoring secondary cities, which are facing increasing problems with proportionally fewer resources at their disposal. The problems of disease in crowded urban environments are discussed. The author presents examples of cities with declining services and quality of life, such as Kinshasa, as well as examples of more successful city development, such as Curitiba. Prospects for the successful resolution of urban problems are assessed.

    2014-11-01

    Despite the long history of modelling human mobility, we continue to lack a highly accurate approach with low data requirements for predicting mobility patterns in cities. Here, we present a population-weighted opportunities model without any adjustable parameters to capture the underlying driving force accounting for human mobility patterns at the city scale. We use various mobility data collected from a number of cities with different characteristics to demonstrate the predictive power of our model. We find that insofar as the spatial distribution of population is available, our model offers universal prediction of mobility patterns in good agreement with real observations, including distance distribution, destination travel constraints and flux. By contrast, the models that succeed in modelling mobility patterns in countries are not applicable in cities, which suggests that there is a diversity of human mobility at different spatial scales. Our model has potential applications in many fields relevant to mobility behaviour in cities, without relying on previous mobility measurements. PMID:25232053

    The City of Tallahassee's Innovative Energy Initiatives program sought, first, to evaluate customer response and acceptance to in-home Smart Meter-enabled technologies that allow customers intelligent control of their energy usage. Additionally, this project is in furtherance of the City of Tallahassee's ongoing efforts to expand and enhance the City's Smart Grid capacity and give consumers more tools with which to effectively manage their energy consumption. This enhancement would become possible by establishing an "operations or command center" environment that would be designed as a dual use facility for the City's employees - field and network staff - and systems responsible for a Smart Grid network. A command center would also support the City's Office of Electric Delivery and Energy Reliability's objective to overcome barriers to the deployment of new technologies that will ensure a truly modern and robust grid capable of meeting the demands of the 2151 century.

    Climate change will require substantial changes to urban environments. Cities are huge sources of greenhouse gases. Further, cities will suffer tremendously under climate change due to heat stresses, urban flooding, energy and water supply and demand changes, transportation problems, resource supply and demand and a host of other trials and tribulations. Cities that evolve most quickly and efficiently to deal with climate change will likely take advantage of the changes to create enjoyable, healthy and safer living spaces for families and communities. Technology will provide much of the capability to both mitigate and adapt our cities BUT education and coordination of citizen and community lifestyle likely offers equal opportunities to make our cities more sustainable and more enjoyable places to live. This work is the first phase of a major project evaluating urban mitigation and adaptation policies, programs and technologies. All options are considered, from changes in engineering, planning and management; and including a range of citizen and population-based lifestyle practices.

  20. Workforce mobility: Contributing towards smart city

    Nor, N. M.; Wahap, N. A.

    2014-02-01

    Smart cities gained importance as a means of making ICT enabled services and applications available to the citizens, companies and authorities that form part of a city's system. It aims at increasing citizen's quality of life, and improving the efficiency and quality of the services provided by governing entities and businesses. This perspective requires an integrated vision of a city and of its infrastructures in all components. One of the characteristics of a smart city is mobility. The concept of mobility, especially for the workforce, is studied through a research carried out on a daily work undertaken as a prototype in the administrative town of Putrajaya, Malaysia. Utilizing the location track from GNSS integrated with mobile devices platform, information on movement and mobility was analysed for quality and efficiency of services rendered. This paper will highlight the research and outcomes that were successfully carried out and will suggest that workforce mobility management can benefit the authorities towards implementing a smart city concept.

  9. The Uses of Big Data in Cities.

    PubMed

    Bettencourt, Luís M A

    2014-03-01

    There is much enthusiasm currently about the possibilities created by new and more extensive sources of data to better understand and manage cities. Here, I explore how big data can be useful in urban planning by formalizing the planning process as a general computational problem. I show that, under general conditions, new sources of data coordinated with urban policy can be applied following fundamental principles of engineering to achieve new solutions to important age-old urban problems. I also show that comprehensive urban planning is computationally intractable (i.e., practically impossible) in large cities, regardless of the amounts of data available. This dilemma between the need for planning and coordination and its impossibility in detail is resolved by the recognition that cities are first and foremost self-organizing social networks embedded in space and enabled by urban infrastructure and services. As such, the primary role of big data in cities is to facilitate information flows and mechanisms of learning and coordination by heterogeneous individuals. However, processes of self-organization in cities, as well as of service improvement and expansion, must rely on general principles that enforce necessary conditions for cities to operate and evolve. Such ideas are the core of a developing scientific theory of cities, which is itself enabled by the growing availability of quantitative data on thousands of cities worldwide, across different geographies and levels of development. These three uses of data and information technologies in cities constitute then the necessary pillars for more successful urban policy and management that encourages, and does not stifle, the fundamental role of cities as engines of development and innovation in human societies.

    The rapid technological evolution, which is characterizing all the disciplines involved within the wide concept of smart cities, is becoming a key factor to trigger true user-driven innovation. However to fully develop the Smart City concept to a wide geographical target, it is required an infrastructure that allows the integration of heterogeneous geographical information and sensor networks into a common technological ground. In this context 3D city models will play an increasingly important role in our daily lives and become an essential part of the modern city information infrastructure (Spatial Data Infrastructure). The work presented in this paper describes an innovative Services Oriented Architecture software platform aimed at providing smartcities services on top of 3D urban models. 3D city models are the basis of many applications and can became the platform for integrating city information within the Smart-Cites context. In particular the paper will investigate how the efficient visualisation of 3D city models using different levels of detail (LODs) is one of the pivotal technological challenge to support Smart-Cities applications. The goal is to provide to the final user realistic and abstract 3D representations of the urban environment and the possibility to interact with a massive amounts of semantic information contained into the geospatial 3D city model. The proposed solution, using OCG standards and a custom service to provide 3D city models, lets the users to consume the services and interact with the 3D model via Web in a more effective way.

  12. Daily Water Use in Nine Cities

    NASA Astrophysics Data System (ADS)

    Maidment, David R.; Miaou, Shaw-Pin

    1986-06-01

    Transfer functions are used to model the short-term response of daily municipal water use to rainfall and air temperature variations. Daily water use data from nine cities are studied, three cities each from Florida, Pennsylvania, and Texas. The dynamic response of water use to rainfall and air temperature is similar across the cities within each State; in addition the responses of the Texas and Florida cities are very similar to one another while the response of the Pennsylvania cities is more sensitive to air temperature and less to rainfall. There is little impact of city size on the response functions. The response of water use to rainfall depends first on the occurrence of rainfall and second on its magnitude. The occurrence of a rainfall more than 0.05 in./day (0.13 cm/day) causes a drop in the seasonal component of water use one day later that averages 38% for the Texas cities, 42% for the Florida cities, and 7% for the Pennsylvania cities. In Austin, Texas, a spatially averaged rainfall series shows a clearer relationship with water use than does rainfall data from a single gage. There is a nonlinear response of water use to air temperature changes with no response for daily maximum air temperatures between 40° and 70°F (4-21°C) an increase in water use with air temperature beyond 70°F; above 85°-90°F (29°-32°C) water use increases 3-5 times more per degree than below that limit in Texas and Florida. The model resulting from these studies can be used for daily water use forecasting and water conservation analysis.

    PubMed

    Wulf, D; Willson, P D

    1984-01-01

    At the 1984 United Nations International Conference on Population held in August, delegates from 149 countries affirmed that population dynamics are an intrinsic part of development and that all people, including adolescents, have a right to family planning information and services. Despite concern for continued US support for population activities, the US delegation in Mexico City clearly emphasized its government's commitment to increased funding. The conference also accepted by acclamation the Mexico City Declaration on Population and Development drafted by 29 countries which stresses the importance of increased funding for population policy, the urgent need to improve women's status and the concern for the effects of the deepening economic crisis, Legal abortion and voluntary sterilization as fertility determinants were ignored. The meeting put to rest any notion that population and development activities are competing spheres of action. In contrast to its 1974 position, the US emphasized entrepreneurial initiative within a free-market system as a stimulus to economic development. The status of women was a major issue brought up by the delegations of Zimbabwe and Australia. The crucial but uncertain issue of funding was addressed by most country represehntatives and most developed countries pledged at least continued if not increased funding for development programs. Most discussion on the abortion issue was almost universally based on repudiation of the procedure as a family planning method. The role of the US in the abortion issue is discussed. The US criticized 2 international agencies that provide most of family planning services to which the US provides funding but which are promoting abortion through affiliates. The US affirmed it would not participate in or assist abortion promotion as a birth control method. The nature and scope of the current economic world crisis caused profound differences between the US and most developing countries' delegations

  14. Putting renewable energy to work in cities

    NASA Astrophysics Data System (ADS)

    McPerson, B.; Mara, G.; Courier, K.; Finneran, K.

    The purpose of the book is to supply city officials with information needed to develop local policies that encourage the use of energy conservation and renewable energy technologies. The basic assumptions are that city energy officials need technical information, that urban energy managers must be conscious of the constraints and opportunities posed by existing conditions and that no urban program can afford to overlook the links between energy and housing, employment, and economic development. Part One contains guidelines to help local energy officials assess their own urban energy contexts. Parts Two and Three indicate how different energy technologies might fit within different city contexts or neighborhoods.

    Events occurring during the past four years which led to the City of Burbank's decision to acquire an energy source adequate for the city's present and future power requirements are discussed. The community reaction to this unprecedented move is also covered. Burbank's long-range plans for the development of geothermal energy are outlined as well as the challenges which confront a public utility in implementing its projected goals.

  18. Understanding the City Size Wage Gap*

    PubMed Central

    Baum-Snow, Nathaniel; Pavan, Ronni

    2013-01-01

    In this paper, we decompose city size wage premia into various components. We base these decompositions on an estimated on-the-job search model that incorporates latent ability, search frictions, firm-worker match quality, human capital accumulation and endogenous migration between large, medium and small cities. Counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to observed city size wage premia. Variation in returns to experience is more important for generating wage premia between large and small locations while differences in wage intercepts are more important for generating wage premia betwen medium and small locations. Sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm-worker match quality contribute little to observed city size wage premia. These conclusions hold for separate samples of high school and college graduates. PMID:24273347

    One of the main concept objectives of smart cities is to create a quality living environment that is long-term sustainable and economically justified. In that context, modern cities are aware of the exposure to various forms of physical and non-physical pollution that needs to be remediated, eliminated or reduced. To achieve that it is necessary to quality determine the sources and reasons of each pollution. The most prominent examples of physical pollution that affects the quality of life of citizens in cities are light and noise pollution. Noise pollution or noise, is mostly the consequence of road and rail traffic in cities and it directly affects the health of citizens. Traffic control, reduction of peak congestion, dispersion and traffic redirection or building protective barriers, are ways that cities use to reduce the amount of noise or its effects. To make these measures efficient it is necessary to obtain the information related to the level of noise in certain areas, streets, cities. To achieve this, smart cities use noise mapping. The city of Zagreb since 2012, participates in the i-SCOPE project (interoperable Smart City services trough Open Platform for urban Ecosystems). i-SCOPE delivers an open platform on top of which it develops, three "smart city" services: optimization of energy consumption through a service for accurate assessment of solar energy potential and energy loss at building level, environmental monitoring through a real-time environmental noise mapping service leveraging citizen's involvement will who act as distributed sensors city-wide measuring noise levels through an application on their mobile phones and improved inclusion and personal mobility of aging and diversely able citizens through an accurate personal routing service. The students of Faculty of Geodesy University of Zagreb, who enrolled in the course Thematic Cartography, were actively involved in the voluntary data acquisition in order to monitor the noise in real time

  2. MATRIX City: A Multi-Risk Platform

    2012-04-01

    MATRIX City (the MATRIX Common IT sYstem) is the computational platform that is being developed in the course of the New Multi-Hazard and Multi-Risk Assessment Methods for Europe (MATRIX) project. MATRIX aims to develop multi-type hazard and risk assessment and mitigation tools suited to the European context. The core of MATRIX City is a risk engine of a novel type that is based on a sequential simulation approach, which allows to quantify interactions and other time-dependent processes at the hazard, exposure, vulnerability and risk levels. For risk estimation in realistic scenarios, data availability is crucial. To overcome this limitation, MATRIX City provides a component called Virtual City. It is a collection of heuristic databases, which provides a generic approach to quantifying multi-type hazard and risk when data coverage is poor, and for sensitivity analysis. MATRIX City results are intended to provide a "big picture" of the expected impact of multi-type hazard and risk modelling (as opposed to static modelling), thus being a valuable tool for decision support. MATRIX City development uses a modern software engineering approach (test-driven development, continuous integration). The architecture is flexible, so that new perils, new models and large datasets can be accommodated easily. However, it should be noted that hazard computation is not part of MATRIX City. Hazard footprints have to be provided as input data, as well as exposure and vulnerability. The data model used in MATRIX City is an enhancement of the Natural hazards' Risk Markup Language (NRML). An XML serialization of this data model, which is a GML (Geographic Markup Language) application schema, is used for data interchange.

    Brochure describes the Clean Cities program and includes the contact information for its 85 coalitions. Sponsored by the U.S. Department of Energy's (DOE) Vehicle Technologies Program (VTP), Clean Cities is a government-industry partnership that reduces petroleum consumption in the transportation sector. Clean Cities contributes to the energy, environmental, and economic security of the United States by supporting local decisions to reduce our dependence on imported petroleum. Established in 1993 in response to the Energy Policy Act (EPAct) of 1992, the partnership provides tools and resources for voluntary, community-centered programs to reduce consumption of petroleum-based fuels. In nearly 100 coalitions, government agencies and private companies voluntarily come together under the umbrella of Clean Cities. The partnership helps all parties identify mutual interests and meet the objectives of reducing the use of petroleum, developing regional economic opportunities, and improving air quality. Clean Cities deploys technologies and practices developed by VTP. These include idle-reduction equipment, electric-drive vehicles, fuel economy measures, and renewable and alternative fuels, such as natural gas, liquefied petroleum gas (propane), electricity, hydrogen, biofuels, and biogas. Idle-reduction equipment is targeted primarily to buses and heavy-duty trucks, which use more than 2 billion gallons of fuel every year in the United States while idling. Clean Cities fuel economy measures include public education on vehicle choice and fuel-efficient driving practices.

    The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local.

    Mexico City is one of the most populated cities in the world with almost 22 million inhabitants, located at an altitude of 2200 m. The old city was founded on an ancient lake and the zone is known by its high seismicity; indoor radon determination is an important public health issue. In this paper the data of indoor radon levels in Mexico City, measured independently by two research groups, both using Nuclear Track Detector systems but different methodologies, are correlated. The measurements were done during similar exposure periods of time, at family houses from the political administrative regions of the city. The results indicate a correlation coefficient between the two sets of data of R = 0.886. Most of the differences between the two sets of data are inherent to houses having extreme (very high or very low indoor radon) included in the statistics of each group. The total average indoor radon found in Mexico City considering the two methods was 87 Bq m{sup -3}.

    People make a city, making each city as unique as the combination of its inhabitants. However, some cities are similar and some cities are inimitable. We examine the social structure of 10 different cities using Twitter data. Each city is decomposed to its communities. We show that in many cases one city can be thought of as an amalgamation of communities from another city. For example, we find the social network of Manchester is very similar to the social network of a virtual city of the same size, where the virtual city is composed of communities from the Bristol network. However, we cannot create Bristol from Manchester since Bristol contains communities with a social structure that are not present in Manchester. Some cities, such as Leeds, are outliers. That is, Leeds contains a particularly wide range of communities, meaning we cannot build a similar city from communities outside of Leeds. Comparing communities from different cities, and building virtual cities that are comparable to real cities, is a novel approach to understand social networks. This has implications when using social media to inform or advise residents of a city. PMID:26998323

    Zhou, M; Mulley, S

    1994-01-01

    China's rural-urban migration flows, particularly into Shanghai, Guangdong province, Beijing, and coastal areas, present challenges for urban development. The impact on rural and urban areas and suggestions for minimizing undesirable consequences were discussed. Professor Zhang Qingwu, deputy director of the Population Research Institute of Xiamen University in Fujian province, believes that the large migrating populations and those without residence cards pose problems for heavily populated cities: they strain resources (housing, water and electricity supplies, transportation, telecommunication, environmental hygiene, food supplies, and educational facilities). Crime increases. Municipal departments must increase their administrative load in service sectors. The general idea is that rural-to-urban migration reflects social progress and adds to a productive work force. Flexible policies are recommended. In Guangdong province, where migrants arrived from Sichuan and Hunan provinces, counties from the latter two provinces have established offices for supervising their former residents. Employment adjustment can be anticipated when the major flock of migrants arrive after the Lantern Festival. Professor Gui Shixun of the Population Research Institute of East China Normal University and advisor to the State Family Planning Commission recommends that development strategies incorporate planning for imbalances between local population and migrant urban workers. In some areas, women represent the bulk of migrants, while in other areas men do. Cultural development should be stressed, with investments also improved in telecommunications, traffic and transportation, education, and hygiene. Professor Jiang Zhixue recommends shifting from labor-intensive enterprises to technology-intensive enterprises and a better trained work force. Other schemes, such as the purchase by migrants of residence cards in Xiamen, would entitle migrants to the same rights and obligations as

  12. Development, primacy, and systems of cities.

    PubMed

    El-shakhs, S

    1972-10-01

    The relationship between the evolutionary changes in the city size distribution of nationally defined urban systems and the process of socioeconomic development is examined. Attention is directed to the problems of defining and measuring changes in city size distributions, using the results to test empirically the relationship of such changes to the development process. Existing theoretical structures and empirical generalizations which have tried to explain or to describe, respectively, the hierarchical relationships of cities are represented by central place theory and rank size relationships. The problem is not that deviations exist but that an adequate definition is lacking of urban systems on the 1 hand, and a universal measure of city size distribution, which could be applied to any system irrespective of its level of development, on the other. The problem of measuring changes in city size distributions is further compounded by the lack of sufficient reliable information about different systems of cities for the purposes of empirical comparative analysis. Changes in city size distributions have thus far been viewed largely within the framework of classic equilibrium theory. A more differentiated continuum of the development process should replace the bioplar continuum of underdeveloped developed countries in relating changes in city size distribution with development. Implicit in this distinction is the view that processes which influence spatial organization during the early formative stages of development are inherently different from those operating during the more advanced stages. 2 approaches were used to examine the relationship between national levels of development and primacy: a comparative analysis of a large number of countries at a given point in time; and a historical analysis of a limited sample of 2 advanced countries, the US and Great Britain. The 75 countries included in this study cover a wide range of characteristics. The study found a

  13. Study of City Landscape Heritage Using Lidar Data and 3d-City Models

    2015-04-01

    In contemporary town planning protection of urban landscape is a significant issue. It regards especially those cities, where urban structures are the result of ages of evolution and layering of historical development process. Specific panoramas and other strategic views with historic city dominants can be an important part of the cultural heritage and genius loci. Other hand, protection of such expositions introduces limitations for future based city development. Digital Earth observation techniques creates new possibilities for more accurate urban studies, monitoring of urbanization processes and measuring of city landscape parameters. The paper examines possibilities of application of Lidar data and digital 3D-city models for: a) evaluation of strategic city views, b) mapping landscape absorption limits, and c) determination protection zones, where the urbanization and buildings height should be limited. In reference to this goal, the paper introduces a method of computational analysis of the city landscape called Visual Protection Surface (VPS). The method allows to emulate a virtual surface above the city including protection of a selected strategic views. The surface defines maximum height of buildings in such a way, that no new facility can be seen in any of selected views. The research includes also analyses of the quality of simulations according the form and precision of the input data: airborne Lidar / DSM model and more advanced 3D-city models (incl. semantic of the geometry, like in CityGML format). The outcome can be a support for professional planning of tall building development. Application of VPS method have been prepared by a computer program developed by the authors (C++). Simulations were carried out on an example of the city of Dresden.

    Concerns about deterioration of the quality of life in mega-cities in India, thought to be due to in-migration, are shown to be misplaced in this essay. Not only is the deterioration due merely to rising expectations, but its causes are problems on a national level. It is true that population growth in the 12 largest cities in India, 3.35%, is more rapid than growth rates in the country as a whole, 2.22%. Bangalore is growing the fastest, 5.68% annually, but generally Indian cities are growing less rapidly that many other Asian cities, e.g. Dacca, 7.37%. Urbanization to the extent of 60.70% of the population is in fact necessary for development. The primary reason for in-migration is employment for men, and marriage accompanying employed husbands for women. Contrary to common opinion, the educational status of in- migrants is higher than that of the region, and female literacy is higher in cities than in the rest of the state, e.g., 61% for Bombay, vs. 35% in Maharashtra State. The occupational status is frequently high: production, transport equipment operator, laborer, professional, technical executive managerial, sales and service. Furthermore, as urbanization proceeds, construction laborers and service workers are in demand. Quality of life defined by infant and maternal mortality is higher in cities than in the surrounding rural area. This quality of life is the reason why people migrate to the city. Unfortunately, frustrations are also rising as expectations for improved housing, water, air, transportation and consumer-durables rise faster than they can be supplied. PMID:12343049

    Recent developments in the massive 3D acquisition area made possible the generation of dense and precise 3D data, ranging from the representation of a simple building to a whole city. Nowadays, increasing urbanization, rapid growth of urban areas, and subsequently development of mega cities, are among the most important changes occurring worldwide. Therefore, developing techniques to manage these cities seems quite necessary. The aim of this paper is to investigate the enrichment of a 3D City Model with additional attributes, via appropriate CityGML Modules. The paper focuses on addressing the challenging issues that derive from a complex virtual 3D city modeling. More specifically, the paper investigates a complex built-up area, presenting and analyzing its constituting structures. Within this framework, the following CityGML modules are investigated: Bridge, Transportation Complex, CityFurniture, Land Use and Vegetation. To this purpose, the BIM-Standard software Trimble SketchUp and the data conversion tool FME are used. The processes of both modeling and converting are analyzed in detail. General conclusions and future research considerations are presented.

    2012-04-01

    Air pollution is one of the hot topics on nowadays studies. This problem is often encountered on urban centers, especially on metropolitan areas. These areas are usually characterized by densely population, heavy traffic rates and the presence of many industrial plants on their suburbs. Problems regarding to air pollution on these areas are more evident over metropolitan areas in developing countries. Air pollution is mostly related to health effects, especially in outdoor environments. These effects regards primarily on respiratory and cardiovascular diseases. Air pollution assessment on a specific area requires not only the estimation of pollutant concentrations in that area, but also determination of their principal sources as well as prediction of eventual scenarios on the area under investigation. This study is focused on air pollution assessment on the city of Tirana, which is the major urban centre and the capital city of Albania. This city has about one million inhabitants. During the last 20 years, its population has grown about four fold, and it is still growing. Because of Albania is a developing country, its capital city is involved on serious environmental problems. Considering these facts, we have conducted continuous monitoring campaigns on several sites of Tirana. These monitoring campaigns consist on measurement of several pollutant gases (SO2, CO, CO2, NOx, etc.) and particulate matter over a period of 20 months. In this paper there are obtained diurnal and annual variations of pollutant concentrations, there is modeled their spatial distributions over the area of the city, and there are estimated the potential contributions of principal sources like traffic and industrial plants. During the entire monitoring campaign there are recorded also meteorological parameters, like temperature, relative humidity, atmospheric pressure, wind speed, wind direction, precipitations, etc. In this way we have tried to obtain the correlations between pollutant

    Urban shrinkage is not a new phenomenon. It has been documented in a large literature analyzing the social and economic issues that have led to population flight, resulting, in the worse cases, in the eventual abandonment of blocks of housing and neighbourhoods. Analysis of urban shrinkage should take into account the new realization that this phenomenon is now global and multidimensional — but also little understood in all its manifestations. Thus, as the world's population increasingly becomes urban, orthodox views of urban decline need redefinition. The symposium includes articles from 10 urban analysts working on 30 cities around the globe. These analysts belong to the Shrinking Cities International Research Network (SCIRN), whose collaborative work aims to understand different types of city shrinkage and the role that different approaches, policies and strategies have played in the regeneration of these cities. In this way the symposium will inform both a rich diversity of analytical perspectives and country-based studies of the challenges faced by shrinking cities. It will also disseminate SCIRN's research results from the last 3 years.

    Dynamic social media content, such as Twitter messages, can be used to examine individuals’ beliefs and perceptions. By analyzing Twitter messages, this study examines how Twitter users exchanged and recognized toponyms (city names) for different cities in the United States. The frequency and variety of city names found in their online conversations were used to identify the unique spatiotemporal patterns of “geographical awareness” for Twitter users. A new analytic method, Knowledge Discovery in Cyberspace for Geographical Awareness (KDCGA), is introduced to help identify the dynamic spatiotemporal patterns of geographic awareness among social media conversations. Twitter data were collected across 50 U.S. cities. Thousands of city names around the world were extracted from a large volume of Twitter messages (over 5 million tweets) by using the Twitter Application Programming Interface (APIs) and Python language computer programs. The percentages of distant city names (cities located in distant states or other countries far away from the locations of Twitter users) were used to estimate the level of global geographical awareness for Twitter users in each U.S. city. A Global awareness index (GAI) was developed to quantify the level of geographical awareness of Twitter users from within the same city. Our findings are that: (1) the level of geographical awareness varies depending on when and where Twitter messages are posted, yet Twitter users from big cities are more aware of the names of international cities or distant US cities than users from mid-size cities; (2) Twitter users have an increased awareness of other city names far away from their home city during holiday seasons; and (3) Twitter users are more aware of nearby city names than distant city names, and more aware of big city names rather than small city names.

    We introduce Instagram as a data source for use by scholars in urban studies and neighboring disciplines and propose ways to operationalize key concepts in the study of cities. These data can help shed light on segregation, the formation of subcultures, strategies of distinction, and status hierarchies in the city. Drawing on two datasets of geotagged Instagram posts from Amsterdam and Copenhagen collected over a twelve-week period, we present a proof of concept for how to explore and visualize sociospatial patterns and divisions in these two cities. We take advantage of both the social and the geographic aspects of the data, using network analysis to identify distinct groups of users and metrics of unevenness and diversity to identify socio-spatial divisions. We also discuss some of the limitations of these data and methods and suggest ways in which they can complement established quantitative and qualitative approaches in urban scholarship.

    Dealing with complex environmental issues frequently inhibits redevelopment of industrial sites in urban settings. In 1993, the City of Chicago (City) Department of Planning and Development, Department of Buildings, and Mayor`s Office joined the Department of Environment to investigate reuse of former industrial/commercial properties (brownfields) suspected of environmental or industrial contamination. The collective result is the Brownfield Program, a three-pronged initiative: Brownfield Pilot Program, Brownfield Forum, and Brownfield Research. Black and Veatch Waste Science, Inc. (Waste Science) carried the Brownfield Program forward by performing a Phase 1 environmental site assessment for the City on one of five pilot sites. Waste Science subsequently completed a Phase 2 environmental site assessment and Phase 3 site remediation at the site. Waste oil and PCB-contaminated soil was removed.

    The discovery of the two cities of Herakleion and East Canopus under the waters of the Bay of Abu Qir (east of Alexandria, Egypt) stirred worldwide attention when it was first announced in the summer of 2000. Their disappearance some 1,250 years ago has been ascribed by Stanley, Goddio and Schnepp to a strong Nile flood that caused riverbank failure and the destruction of the two cities, rather than to the action of earthquakes, as was first proposed when the ruins were discovered. But I believe that this interpretation is flawed, because no flood could have reached the Abu Qir Bay at the time of the disappearance of the two cities, as the Canopic branch of the Nile, along whose banks they were situated, had dried to a trickle more than 200 years earlier.

  8. Mapping the earth conductivity-depth structure of African geomagnetic equatorial anomaly regions using solar quiet current variations

    The solar quiet day ionospheric (Sq) current variations observed in Abuja, Bangui and Addis Ababa were used to delineate the mantle conductivity-depth structure along the equatorial African regions. Spherical harmonic analysis (SHA) was employed in separating the internal and external field contributions to the Sq variations. For each of the paired external and internal coefficients of the SHA, we used transfer function to compute the conductivity-depth profile for the region. Strikingly, we observed increased electrical conductivity values in the Earth layers and deep depth penetration. The calculated average electrical conductivity values in Addis Ababa and Abuja are 0.087 Sm-1 and 0.104 Sm-1 at depths of 93 km and 121 km respectively. These values suddenly rose to 0.235 Sm-1 and 0.222 Sm-1 at depths of 440 km and 427 km respectively. In Bangui, the calculated average values are 0.092 Sm-1, 0.144 Sm-1, 0.312 Sm-1 and 0.466 Sm-1 at 96 km, 300 km, 834 km and 1228 km depths respectively. At the greatest depths of penetration of 1412 km, 1385 km and 1278 km in Addis Ababa, Abuja and Bangui, the electrical conductivity attained the highest values of 0.415 Sm-1, 0.467 Sm-1 and 0.515 Sm-1 respectively. Two most Earth conductive layers were discovered in the magnetic equatorial zone. These layers lie between the depth of about 100 and 400 km within the upper mantle and beyond 1200 km in the lower mantle. It can be inferred that the closer one goes towards the Earth magnetic equator; the deeper the Sq current can penetrate the Earth's interior.

    Since the 1960s, lesbian, gay, bisexual, transgender and queer (LGBTQ) culture has developed in big cities and metropolises everywhere (not only in the West, but also in Asia, Latin America and indeed Africa). This essay examines how cities provide the spatial conditions necessary for the formation of such emancipatory movements based on identity politics and strategies which transcend binary gender dualism. The starting point of this investigation is my thesis that only urban life enables LGBTQ individuals to live their lives fully, realize their (sexual) identities, and furthermore organize themselves collectively, become publicly visible, and appropriate urban, societal and political spaces.

    The vision of ''Smart Cities'' is the urban center of the future, made safe, secure environmentally green, and efficient because all structures--whether for power, water, transportation, etc. are designed, constructed, and maintained making use of advanced, integrated materials, sensors, electronics, and networks which are interfaced with computerized systems comprised of databases, tracking, and decision-making algorithms. This paper discusses a current initiative being led by the Brookhaven National Laboratory to create a research, development and deployment agenda that advances this vision. This is anchored in the application of new technology to current urban center issues while looking 20 years into the future and conceptualizing a city framework that may exist.

    2014-12-01

    We present a method for automatically identifying and validating predictive relationships between the visual appearance of a city and its non-visual attributes (e.g. crime statistics, housing prices, population density etc.). Given a set of street-level images and (location, city-attribute-value) pairs of measurements, we first identify visual elements in the images that are discriminative of the attribute. We then train a predictor by learning a set of weights over these elements using non-linear Support Vector Regression. To perform these operations efficiently, we implement a scalable distributed processing framework that speeds up the main computational bottleneck (extracting visual elements) by an order of magnitude. This speedup allows us to investigate a variety of city attributes across 6 different American cities. We find that indeed there is a predictive relationship between visual elements and a number of city attributes including violent crime rates, theft rates, housing prices, population density, tree presence, graffiti presence, and the perception of danger. We also test human performance for predicting theft based on street-level images and show that our predictor outperforms this baseline with 33% higher accuracy on average. Finally, we present three prototype applications that use our system to (1) define the visual boundary of city neighborhoods, (2) generate walking directions that avoid or seek out exposure to city attributes, and (3) validate user-specified visual elements for prediction.

    Many urban phenomena exhibit remarkable regularity in the form of nonlinear scaling behaviors, but their implications on a system of networked cities has never been investigated. Such knowledge is crucial for our ability to harness the complexity of urban processes to further sustainability science. In this paper, we develop a dynamical modeling framework that embeds population-resource dynamics-a generalized Lotka-Volterra system with modifications to incorporate the urban scaling behaviors-in complex networks in which cities may be linked to the resources of other cities and people may migrate in pursuit of higher welfare. We find that isolated cities (i.e., no migration) are susceptible to collapse if they do not have access to adequate resources. Links to other cities may help cities that would otherwise collapse due to insufficient resources. The effects of inter-city links, however, can vary due to the interplay between the nonlinear scaling behaviors and network structure. The long-term population level of a city is, in many settings, largely a function of the city's access to resources over which the city has little or no competition. Nonetheless, careful investigation of dynamics is required to gain mechanistic understanding of a particular city-resource network because cities and resources may collapse and the scaling behaviors may influence the effects of inter-city links, thereby distorting what topological metrics really measure.

    The OGO 4 and 6 (POGO) magnetic field results for the equatorial electrojet indicate that while the present models are approximately correct, the possibility of a westward component must be incorporated. The scatter diagrams of POGO amplitudes and surface data show a correlation. The ratios between the amplitudes estimated from surface data and those at 400 km altitude are as follows: India 5 to 8, East Africa (Addis Ababa) 4, Central Africa 3, West Africa (Nigeria) 3, South America (Huancayo) 5, and Philippines 5. The variation in the ratio is due to the conductivity structure of the earth in various zones.

    The dietary pattern, physical work output, and blood lipids were studied in three groups of healthy, young, urban Ethiopian men differing in the degree of "Westernization." The results showed striking increases in serum lipids that were associated with the degree of Westernization of the diet. These changes could not be accounted for by differences in other group characteristics such as age, weight, smoking, or length of residence in Addis Ababa. The effects of the level of physical work output on serum lipids were equivocal because the methods used for the assessment of energy output yielded crude approximations only.

    With the application of the principles of landscape ecology and the techniques of geographic information systems, the landscape of Jiaozuo city was divided into six types, i. e., farmland, garden plot, woodland, residential and industrial area, waters, and others. The landscape diversity, dominance, fragmentation, and isolation indexes were calculated by models and GIS to analyze the spatial patterns of these landscape types. Based on the optimization of landscape spatial patterns, a pattern for developing a rational and natural ecosystem in Jiaozuo city was proposed, i. e., keeping four or five large natural patches, planning small artificial green patches, linking the large and small patches by various corridors to ensure the ecosystem inside the city to circulate well, combining residential areas properly to form a urban troop with Jiaozuo town as the center and with seven surrounding towns joined through highways to form a network city pattern. After doing these, urban built-up areas could be linked each other, and inlayed in a natural ecological matrix. This pattern could strengthen the ecological connection, raise the stability of the ecosystem, and maintain the balance of urban ecological system.

  5. Determinants of urban sprawl in European cities

    PubMed Central

    Alvanides, Seraphim; Garrod, Guy

    2015-01-01

    This paper provides empirical evidence that helps to answer several key questions relating to the extent of urban sprawl in Europe. Building on the monocentric city model, this study uses existing data sources to derive a set of panel data for 282 European cities at three time points (1990, 2000 and 2006). Two indices of urban sprawl are calculated that, respectively, reflect changes in artificial area and the levels of urban fragmentation for each city. These are supplemented by a set of data on various economic and geographical variables that might explain the variation of the two indices. Using a Hausman-Taylor estimator and random regressors to control for the possible correlation between explanatory variables and unobservable city-level effects, we find that the fundamental conclusions of the standard monocentric model are valid in the European context for both indices. Although the variables generated by the monocentric model explain a large part of the variation of artificial area, their explanatory power for modelling the fragmentation index is relatively low.

  4. Inflation, economic policy, and the inner city

    SciTech Connect

    Curtis, L.A.

    1981-07-01

    This article describes the greater impact of inflation among the poor and minorities in American inner cities than among other population groups. Surveys show, however, that minorities are even more concerned over unemployment and racial discrimination than over inflation. There are indications that, especially today, crime and potential group disorder are affected by or influence inflation, unemployment, and discrimination in the inner city. With these interrelated factors in mind, present federal economic policy is reviewed, critiqued, and interpreted as basically consistent with Keynesian economic theory. Modifications of and alternatives to present policy are offered that fit both inner-city needs and the concerns of the rest of American society. These policies include targeted private sector neighborhood development and self-help, private sector productivity increases through workplace democracy, private-public sector codetermination of investment, private-public sector job guarantees, and public anti-inflation policy carefully targeted at the basic necessities of energy, food, housing, and health care - which have a disproportionate effect on inflation in the inner city, as well as the overall economy. Coalitions are suggested that could politically implement such policies.

  7. Measure the Climate, Model the City

    NASA Astrophysics Data System (ADS)

    Boufidou, E.; Commandeur, T. J. F.; Nedkov, S. B.; Zlatanova, S.

    2011-08-01

    Modern large cities are characterized by a high building concentration, little aeration and lack of green spaces. Such characteristics create an urban climate which is different from the climate outside of cities. An example of an urban climate effect is the so-called Urban Heat Island: cities tend to be warmer than the surrounding rural areas. The higher temperature results in an increase in energy consumption since people, especially in summer, use artificial means to cool themselves. Although means of mitigating the UHI effect exist, they are difficult to justify, as knowledge about urban climate is limited, and analysis tools are lacking. This paper presents the work carried during the 2010 MSc Geomatics Synthesis Project. A 3D spatial relational database has been implemented which is meant to act as starting point in the development of a 3D climate-enabled geographical information system. To this end, the database stores 3D geometries representing the built environment and its thematic properties. The database is also able to store measurements of climate parameters, in this case temperature, obtained through mobile sensors. Spatial analyses and queries are supported, allowing users to calculate areas, distances, buffers, add and remove geometries and thematic attributes. The database design is based on the CityGML information model which has been extended to allow the storage of climate parameters relevant to urban climate research.

  12. Project Wish: The Emerald City, phase 3

    NASA Technical Reports Server (NTRS)

    1992-01-01

    Phase 3 of Project Wish saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the C-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystems constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS while spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System). A structural dynamic analysis also conducted using ASTROS enabled a study of the displacements, accelerations, modes and frequencies of the C-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

  13. With Geospatial in Path of Smart City

    NASA Astrophysics Data System (ADS)

    Homainejad, A. S.

    2015-04-01

    With growth of urbanisation, there is a requirement for using the leverage of smart city in city management. The core of smart city is Information and Communication Technologies (ICT), and one of its elements is smart transport which includes sustainable transport and Intelligent Transport Systems (ITS). Cities and especially megacities are facing urgent transport challenge in traffic management. Geospatial can provide reliable tools for monitoring and coordinating traffic. In this paper a method for monitoring and managing the ongoing traffic in roads using aerial images and CCTV will be addressed. In this method, the road network was initially extracted and geo-referenced and captured in a 3D model. The aim is to detect and geo-referenced any vehicles on the road from images in order to assess the density and the volume of vehicles on the roads. If a traffic jam was recognised from the images, an alternative route would be suggested for easing the traffic jam. In a separate test, a road network was replicated in the computer and a simulated traffic was implemented in order to assess the traffic management during a pick time using this method.

  11. How Cities Make Their Own Weather

    NASA Technical Reports Server (NTRS)

    Shepherd, J. Marshall

    2004-01-01

    Urbanization is one of the extreme cases of land use change. Most of world's population has moved to urban areas. Although currently only 1.2% of the land is considered urban, the spatial coverage and density of cities are expected to rapidly increase in d e near future. It is estimated that by the year 2025, 60% of the world's population will live in cities. Human activity in urban environments also alters weather and climate processes. However, our understanding of urbanization on the total Earth-weather-climate system is incomplete. Recent literature continues to provide evidence that anomalies in precipitation exist over and downwind of major cities. Current and future research efforts are actively seeking to verify these literature findings and understand potential cause-effect relationships. The novelty of this study is that it utilizes rainfall data from multiple satellite data sources (e.g. TRMM precipitation radar, TRMM-geosynchronous-rain gauge merged product, and SSM/I) and ground-based measurements to identify spatial anomalies and temporal trends in precipitation for cities around the world. We will also present results from experiments using a regional atmospheric-land surface modeling system. Early results will be presented and placed within the context of weather prediction, climate assessment, and societal applications.

  11. Mexico City, Mexico as seen from STS-62

    NASA Technical Reports Server (NTRS)

    1994-01-01

    This image is the clearest photo of Mexico City, Mexico taken from U.S. Manned Spacecraft. North is to the upper right. Mexico City sits in a basin surrounded by large volcanoes. The restricted atmospheric circulation in the basin, coupled with the inevitable air emissions produced by a city of 20 million people has created a critical air pollution problem for the city. In most photographs of the region, Mexico City is obscured by haze. The clarity of the photograph allows many key cultural features to be identified, including all of the major boulevards, the horse track (western part of the city), the university (south of the city), and the museum areas. Large, man-made ponds east of the city also stand out.
