Analysis of impervious surfaces and surface temperature over Tshwane metropolitan using in-situ and remotely sensed data
No full textDissertation (MSc)--University of Pretoria, 2015.Tshwane is one of the major metropolitan in Gauteng Province. This metropolitan continues to experience rapid urbanization as a result of population growth, leading to the conversion of natural lands into impervious surface area (ISA) i.e., constructed surfaces – sidewalks, roads rooftops, parkinglots covered by impenetrable materials such as asphalt, concrete and stones which prevent water from infiltrating into the soil. Such landscapes influence the climate of the Metropolitan as evidenced by the recent heat wave characterized by high temperature. Therefore, the consistent information about these changes will play an important role in city planning and environmental management. In this study, seven land use/cover types were delineated from the cloud free Landsat images using maximum likelihood (ML) and random forest (RF) classifiers to map the Tshwane metropolis. The overall accuracies for classifying the seven land cover types were 88.63% and 80.13% (Landsat 7 ETM+, 2003) and 88.82% and 82.03% (Landsat 8 LCDM) for both ML and RF, respectively. In addition, based on the pairwise comparison of error matrix the two algorithms were found to produce approximately identical classification errors. Furthermore, the remote sensing data was also used to assess the relationship between LULC changes and LST estimation. Mean near surface temperature from the weather stations was used as a point of reference to verify the accuracy of the final retrieved LST images. From Landsat 7 ETM+ (2003), the mean pixel temperature for Pretoria Eendracht and Irene Wo weather station when compared the mean near surface temperature produced a LST retrieval error of 3.3OC and 1OC respectively. Similarly, Landsat 8 LCDM data (2013) mean pixel temperature for Pretoria UNISA weather station and Pretoria National Botanical Institute when compared the mean near surface temperature produced a LST retrieval error of 0.38OC and 1.3OC for the two stations. Finally, the remote sensing data showed the quantitative effect of impervious surface area changes on mean LSTs, through the distribution of urban heat island within Tshwane metropolitan.tm2015Geography, Geoinformatics and MeteorologyMScUnrestricte

No full textInternational audiencePerceived workplace violence against nurses has become a major concern to scholars, occupational safety and health administrators. However, dispositional factors in nurses’ perception of workplace violence in Nigeria have not been sufficiently explored. This study therefore, examined dispositional factors predicting workplace violence among nurses in Ondo and Osun State, Nigeria.The study adopted the cross-sectional study across the study setting; four hundred and fifteen (415) nurses from 14 health centres consisting of primary, secondary and tertiary health centres were selected using multi-stage sampling technique. A structured questionnaire which focused on socio-demographic characteristics, perceived workplace violence (α = 0.91), trait anger (TA) (α = 0.67), negative affectivity (NA) (α = 0.96), self control (SC) (α = 0.83) was used. Data was analysed using multiple regression, one-way ANOVA, and independent t-test at p<.05 level of significance.The results reveal that the respondents’ average age was 39.89±12.12 years. Females (83.1%) constituted the larger percentage of the respondents. 64.8% were registered nurses (RN), 28.4% had Nursing degree, 3.4% had Masters’ degree and 2.4% had other qualifications. The nurse worked in the floor shifts (31.6%), critical care (22.9%), intensive care (18.3%) and the operating room (12%) units. Nurses’ trait anger (β = .15), negative affectivity (β = .13) organisational attribution style (β = .15) were significantly associated with frequent experience of perceived workplace violence.In conclusion, nursing staff dispositional traits and attribution styles makes them vulnerable to workplace violence.Понимание насилия на рабочем месте против медсестер стало серьезной проблемой для ученых, администраторов охраны труда и здоровья. Тем не менее, диспозиционные факторы, приводящие к насилием на рабочем месте по медицинских сестер в Нигерии недостаточно изучены. Таким образом, в этом исследовании рассмотрены диспозиционные факторы, которые приводят к насилию на рабочем месте среди медсестер в штате Ондо и Осун, Нигерия.В исследовании было проведено перекрестное исследование по четыреста пятнадцать (415) медсестер с 14 медицинских центров, состоящих из первичных, вторичных и третичных медицинских центров, которые были отобраны с использованием многоступенчатой методики отбора проб. В исследовании были использованы структурированный опросник, который сосредоточен на социально-демографических характеристиках, восприятии насилия на рабочем месте (α = 0,91), гневе признаков (TA) (α = 0,67), отрицательной аффективности (NA) (α = 0 , 96), самоконтроле (SC) (α = 0,83). Данные анализировали с помощью множественной регрессии, односторонней ANOVA и независимого t-теста на р <0,05 уровня значимости.Результаты показывают, что средний возраст респондентов составил 39,89 ± 12,12 лет. Женщины (83,1%) составляли больший процент респондентов. 64,8% были зарегистрированы медсестрами (RN), 28,4% имели степень медсестринства, 3,4% имели степень магистра и 2,4% имели другие квалификации. Медсестра работала в смещениях на полу (31,6%), критической (22,9%), реанимационной (18,3%) и операционной (12%). Состояния гнева медсестер (β = 0,15), негативная аффективность (β = .13) стиля организационной атрибуции (β = .15) существенно ассоциировались с частым опытом восприятия насилия на рабочем месте.Наконец, диспозиционные состояния и характеристики сестринского персонала делают их уязвимыми к насилию на рабочем месте.Розуміння насильства на робочому місці проти медсестр стало серйозною проблемою для науковців, адміністраторів охорони праці та здоров’я. Тим не менш, диспозиційні фактори, що призводять до насильством на робочому місці щодо медичних сестер в Нігерії недостатньо вивчені. Таким чином, у цьому дослідженні розглянуті диспозиційні фактори, які призводять до насильства на робочому місці серед медсестр у штаті Ондо і Осун, Нігерія.У дослідженні було проведено перехресне дослідження щодо чотириста п’ятнадцяти (415) медсестр з 14 медичних центрів, що складаються з первинних, вторинних та третинних медичних центрів, які були відібрані з використанням багатоступеневої методики відбору проб. У дослідженні було використано структурований опитувальник, який зосереджувався на соціально-демографічних характеристиках, сприйнятті насильства на робочому місці (α = 0,91), гніві ознак (TA) (α = 0,67), негативній афективності (NA) (α = 0,96), самоконтролі (SC) (α = 0,83). Дані аналізували за допомогою множинної регресії, односторонньої ANOVA і незалежного t-тесту на р <0,05 рівня значущості.Результати показують, що середній вік респондентів становив 39,89 ± 12,12 років. Жінки (83,1%) становили більший відсоток респондентів. 64,8% були зареєстрованими медсестрами (RN), 28,4% мали ступінь медсестринства, 3,4% мали ступінь магістра та 2,4% мали інші кваліфікації. Медсестра працювала в зміщеннях на підлозі (31,6%), критичній (22,9%), реанімаційній (18,3%) та операційній (12%). Стани гніву медсестр (β = 0,15), негативна афективність (β = .13) стилю організаційної атрибуції (β = .15) суттєво асоціювалися з частим досвідом сприйняття насильства на робочому місці.Нарешті, диспозиційні стани та характеристики сестринського персоналу роблять їх вразливими до насильства на робочому місці
Atmospheric radio refractivity and water vapour density at Oshodi and Kano, Nigeria
No full textSome statistical analyses have been carried out on radiosonde data on atmospheric humidity taken during the period 1990-1993 at two meteorological stations, Oshodi (6° 32'N, 3° 21E) and Kano (12° 5N, 8° 52E) in Nigeria. Monthly means and standard deviations of columnar radio refractivity N and columnar water vapour density ρ have been obtained for the atmospheric columns, 0-3km, 0-10km, and 3-10km. It is found that the correlation coefficient between the monthly means of N and ρ is higher than 0.9 in most of the cases. Consequently, equations of regression have been obtained by means of which measurements of columnar water vapour density ρ can be used to estimate N over Oshodi, and Kano. For instance, line of regression of N upon ρ for Oshodi at the 0-3km atmospheric column is N = (4.93 ± 0.75) ρ + 254.15 ± 11.26.Keywords: atmospheric humidity, columnar radio refractivityNigeria Journal of Pure and Applied Physics Vol. 4(1) 2005: 11-1
Vegetable oils as quenchants for hardening medium carbon steel
No full textGroundnut (Arachia hypoge) oil and palm (Elaeis guineeness) kernel oil were investigated as vegetable quench-ing media for carbon steel (0.45 % C) by determining the characteristic temperature-time cooling curves and rel-ated mechanical properties. The three stages of cooling examined during quenching were vapour blanket, boili-ng and convection. The study was conducted to find vegetable oil alternatives to the commonly used synthetic polymer quenchants, which are considered hazardous, costly and not readily available. The influence of cooling rates of the quenching media on microstructure, tensile strength, yield stress and hardness of medium carbon steel were also investigated. The mechanical properties of groundnut oil quenched steel were higher than palm oil quenched steel, but the wear resistance measured by hardness testing was higher when quenched in palm kernel oil than in groundnut oil

No full textAssessing the penetration, fidelity, and birth outcomes associated with the 2016 WHO antenatal care policy across states in Nigeria
No full textThe World Health Organization (WHO) rolled out the 2016 antenatal care (ANC) policy, including the eight-visit ANC (8vANC) recommendation, to improve women's ANC uptake and ensure positive pregnancy experience. Following the adoption and implementation of the 2016 WHO ANC policy by the Nigerian Federal Ministry of Health in 2017, a national cross-sectional survey conducted in 2021 indicated significant differences in state-level utilization rates of 8vANC. Using a combination of an implementation research approach and multilevel analysis, this study examined the underlying determinants of both the utilization behaviors and selected birth outcomes associated with the 2016 WHO ANC policy in Nigeria.With a post-implementation sample obtained from the Multiple Indicator and Cluster Survey (MICS6) 2021, Aim 1 focused on assessing the underlying determinants attributable to the observed differences in 8vANC utilization. The outcome was defined as the penetration of the WHO 8vANC policy and was measured as the proportion of women who used a minimum of 8vANC out of the total number of women who had live births within two years before the 2021 MICS6. The findings indicated that while women who self-reported their perception of life satisfaction as ‘very happy’ and ‘somewhat happy’ had increased odds of 8vANC utilization across states, the perception of wife beating justified ‘if she goes out without telling husband’ had reduced odds on the penetration of the 8vANC. Aim 2 examined the determinants associated with fidelity to five selected ANC components (the timing of first ANC visit, blood pressure measurement, blood sample test, urinalysis, and tetanus vaccination) among women who completed 8vANC. The findings indicated that 99.7% initiated their first ANC visit within 12 weeks of gestation and the rate of concordance with the five selected ANC components was 83.7%, on average. Aim 3 examined the association of C-sections, low birth weight (LBW), and perinatal death with penetration and fidelity to the policy by generating a main fixed effect labeled as penetration-fidelity. The findings revealed that penetration-fidelity was positively associated with LBW, negatively associated with perinatal death, and insignificantly associated with C-section.Doctor of Philosoph

Socioeconomic characteristics and community participation in infrastructure provision in Akure, Nigeria
No full textCommunity participation is a necessary ingredient for infrastructure projects to enhance the level of residential satisfaction and to improve its success rate. Nevertheless, there are socioeconomic and demographic factors, which determine the level of participation in such projects. This paper examines these factors in the residential neighbourhoods of Akure, Nigeria. Data were collected through structured questionnaires and observations. They were subjected to Single-Factor Descriptive Analysis and Categorical Regression Analysis. It showed that stages of participation in housing development, level of education, tenure status, marital status, gender, monthly income, household size, sources of finance, and employment status were significant predictors of levels of community participation in this context, with the exception of age. A p-value of 0.034 was observed indicating that the model of the regression was significant at 0.05. The paper concludes by providing implications, considering the factors for developing strategies for community participation in infrastructure provision in Nigeria
