African women writers and the politics of gender

This thesis examines the work of a group of African women writers who have emerged over the last forty years. While figures such as Chinua Achebe, Ben Okri and Wole Soyinka are likely to be the chief focus of discussions of African writing, female authors have been at the forefront of fictional interrogations of identity formation and history. In the work of authors such as Mariama Bâ (Senegal), Buchi Emecheta (Nigeria), Chimamanda Ngozi Adichie (Nigeria), Tsitsi Dangarembga (Zimbabwe), and Leila Aboulela (Sudan), there is a clear attempt to subvert the tradition of male writing where the female characters are often relegated to the margins of the culture, and confined to the domestic, private sphere. This body of work has already generated a significant number of critical responses, including readings that draw on gender politics and colonialism; but it is still very much a minor literature, and most mainstream western feminism has not sufficiently processed it. The purpose of this thesis is threefold. First, it draws together some of the most important and influential African women writers of the post-war period and looks at their work, separately and together, in terms of a series of themes and issues, including marriage, family, polygamy, religion, childhood, and education. Second, it demonstrates how African literature produced by women writers is explicitly and polemically engaged with urgent political issues that have both local and global resonance: the veil, Islamophobia and a distinctively African brand of feminist critique. Third, it revisits Fredric Jameson’s claim that all third-world texts are ‘national allegories’ and considers these novels by African women in relation to Jameson’s claim, arguing that their work has complicated Jameson’s assumptions

Serum analyte levels in children: relationship with malnutrition

Malnutrition is the cellular imbalancing among the supply of energy and nutrients which are essential for maintenance, growth and particular functions. It becomes a major cause of mortality of children less than five years of age. The aim of present study to evaluate the serum analytes such as electrolyte (sodium (Na+), potassium (K+) and calcium (Ca+)), creatinine and blood components in malnourished than healthy children. We had collected the data of 300 malnourished children (100 marasmus, 100 kwashiorkorand, 100 healthy children) with age 6-36 months from Children complex Hospital Multan, Pakistan. Data was analyzed by Paired sample t-test by SPSS software. Then socio-demographic data of their mothers was also collected. The result showed that level of Na+ and creatinine was high whereas, the levels of K+ and Ca+ were lower in both Marasmus and Kwashiorkor than control subjects. The levels of leukocytes, platelets and hemoglobin (Hb) were decreased in both diseases. Erythrocytes (RBCs) level was decreased in Marasmus while increased in Kwashiorkor. It is concluded that inadequate feeding practices, birth order, poverty, illiterate mothers, low nutritional quality of meals responsible for malnutrition. Feasible strategies are needed to address the dietary inadequacies and chronic malnutrition of rural infants

Heavy metals and nutritional composition of some selected herbal plants of Soon Valley, Khushab, Punjab, Pakistan

Herbal plants and their extracts deserve special attention because of the important influence they have on human health. For the majority of the world population, herbal plants represent the primary source of the health care. According to the World Health Organization (WHO) report, almost 80% of people in marginal communities use only herbal plants for the treatment of various diseases. Although, the effectiveness of the herbal plants is mainly associated with their constituents such as essential oils, vitamins, glycosides and many other products but prolonged intake can cause health problems due to the presence of heavy metals. The human body requires both the metallic and the non-metallic elements within certain permissible limits for growth and good health. Therefore, the determination of element compositions in food and related products is essential for understanding their nutritive importance. The accumulation of some heavy metals in large quantities in the body may have a toxic effect. The concentration levels ( mg/L) of selected heavy metals (Fe, Mn, Cu, Zn and Pb) and macronutrients (Na, Ca, Mg, K and P) in eight useful herbal plants of Soon Valley District Khushab were determined by atomic absorption spectrophotometer and colorimeter. The herbal plants having different growing seasons and uses were collected from different locations. The results revealed that the herbal plants accumulate the elements at different concentrations. The maximum concentrations ( mg/L) of heavy metals in the analyzed samples were 47.25 ± 0.01, 26.6 ± 0.01, 207.6 ± 0.08, 78.90 ± 0.04 and 0.39 ± 0.01 for Zn, Cu, Fe, Mn and Pb, respectively. The maximum concentrations ( mg/L) of macro elements were 728 ± 0.60, 28300 ± 113, 68500 ± 25, 24250 ± 55 and 3700 ± 299 for Na, K, Mg, Ca and P, respectively. The levels of heavy metals determined in the analyzed samples were found below the maximum allowable limit. Hence they were safe for consumption. Fe was accumulated most among the plants analyzed for heavy metals. The analyzed samples were good source of important macro elements.Keywords: Heavy metals, nutritional composition, medicinal herbs, Soon Valley

IMPACT OF PUBLIC SERVICE MOTIVATION AND ORGANIZATIONAL SOCIAL CAPITAL ON KNOWLEDGE SHARING IN PUBLIC SECTOR

Increasing interest in the idea of gaining synergistic benefits in public sector organizations has triggered the developing as well as developed nations to explore the concept of knowledge sharing (KS) and its relationship with other concepts. Among the most important ones are the concepts of public service motivation (PSM) and organizational social capital (OSC). Keeping in view the increasing interest in these concepts the current study investigates the impact of public service motivation (PSM) and organizational social capital (OSC) on knowledge sharing (KS) in public sector. Two hypotheses were developed in this respect that assumed positive relationships of PSM and OSC on KS. These hypotheses were tested through a proposed model by collecting and analyzing the quantitative data of 270 employees of University of the Punjab. Self-administered questionnaire was used to collect the data. Multiple linear regression through Statistical Package for Social Sciences (SPSS) was used to test the hypotheses. Both hypotheses were supported i.e. public service motivation and organizational social capital have a positive relationship with knowledge sharing. The study shows that the knowledge sharing can be encouraged in organizations by enhancing public service motivation and organizational social capital. It is also recommended that the individual dimensions of public service motivation (PSM) and organizational social capital (OSC) should be studied to have a deeper knowhow of these relationships

Comparative Review on Information and Communication Technology Issues in Education Sector of Developed and Developing Countries: A Case Study About Pakistan

The use of information and communication technology is very beneficial in the education sector because it can enhance the quality of education. However, the implementation of ICT in the education sector of developed and developing countries is a challenging task. This paper explains the comparative study of ICT issues in the education sector of developed and developing countries. In particular, we compare issues between Pakistan and high-tech countries. Our study reveals the fact that the education sector is facing numerous ICT problems that are based on culture, finance, management, infrastructure, lack of training, lack of equipment, teacher’s refusal, and ethical issues. At the end of this paper, various issues faced by the implementation of ICT in the education sector of Pakistan have been categorized into various types, namely, infrastructure, lack of IT professionals, lack of high-speed internet and equipment. Our research is based on five key research questions related to ICT issues. We used a mixed approach where the results of this study can be used as a set of guidelines to help make the learning environment technology-oriented, fast, planned, and productive. Future directions are also given at the end of this paper

Impact of maternal respiratory infections on low birth weight - a community based longitudinal study in an urban setting in Pakistan

Background: The health of mothers and their newborns is intricately related. The weight of the infant at birth is a powerful predictor of infant growth and survival, and is considered to be partly dependent on maternal health and nutrition during pregnancy. We conducted a longitudinal study in an urban community within Karachi to determine maternal predictors of newborn birth weight.Methods: Four hundred pregnant women were enrolled in the study during the period 2011-2013. Data related to symptoms of acute respiratory illness (fever, cough, difficulty breathing, runny nose, sore throat, headache, chills, and myalgia/lethargy) in the pregnant women were collected weekly until delivery. Birth weight of the newborn was recorded within 14days of delivery and the weight of \u3c 2.5kg was classified as low birth weight (LBW).Results: A total of 9,853 symptom episodes were recorded of fever, cough, difficulty breathing, runny nose, sore throat, headache, chills, myalgias/lethargy in the enrolled pregnant women during the study. Out of 243 pregnant women whose newborns were weighed within 14days of birth, LBW proportion was 21% (n=53). On multivariate analysis, independent significant risk factors noted for delivering LBW babies were early pregnancy weight of \u3c 57.5kg [odds ratio adjusted (ORadj)=5.1, 95% CI: (1.3, 19.9)] and gestational age [ORadj=0.3, 95% CI (0.2, 0.7) for every one week increase in gestational age]. Among mothers with high socioeconomic status (SES), every 50-unit increase in the number of episodes of respiratory illness/100weeks of pregnancy had a trend of association with an increased risk of delivering LBW infants [ORadj=1.7, 95% CI: (1.0, 3.1)]. However, among mothers belonging to low SES, there was no association of the number of episodes of maternal respiratory illness during pregnancy with infants having LBW [ORadj=0.9, 95% CI: (0.5, 3.5)].CONCLUSIONS: While overall respiratory illnesses during pregnancy did not impact newborn weight in our study, we found this trend in the sub-group of mothers belonging to the higher SES. Whether this is because in mothers belonging to lower SES, the effects of respiratory illnesses were overshadowed by other risk factors associated with poverty need to be further studied

Bayesian network based procedure for regional drought monitoring:The Seasonally Combinative Regional Drought Indicator

Drought is a complex natural hazard. It occurs due to a prolonged period of deficient in rainfall amount in a certain region. Unlike other natural hazards, drought hazard has a recurrent occurrence. Therefore, comprehensive drought monitoring is essential for regional climate control and water management authorities. In this paper, we have proposed a new drought indicator: the Seasonally Combinative Regional Drought Indicator (SCRDI). The SCRDI integrates Bayesian networking theory with Standardized Precipitation Temperature Index (SPTI) at varying gauge stations in various month/seasons. Application of SCRDI is based on five gauging stations of Northern Area of Pakistan. We have found that the proposed indicator accounts the effect of climate variation within a specified territory, accurately characterizes drought by capturing seasonal dependencies in geospatial variation scenario, and reduces the large/complex data for future drought monitoring. In summary, the proposed indicator can be used for comprehensive characterization and assessment of drought at a certain region

Determinants and impact of giardia infection in the first 2 years of life in the MAL-ED birth cohort

Background: Giardia are among the most common enteropathogens detected in children in low-resource settings. We describe here the epidemiology of infection with Giardia in the first 2 years of life in the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development Project (MAL-ED), a multisite birth-cohort study.Methods: From 2089 children, 34916 stool samples collected during monthly surveillance and episodes of diarrhea were tested for Giardia using an enzyme immunoassay. We quantified the risk of Giardia detection, identified risk factors, and assessed the associations with micronutrients, markers of gut inflammation and permeability, diarrhea, and growth using multivariable linear regression.Results: The incidence of at least 1 Giardia detection varied according to site (range, 37.7%-96.4%) and was higher in the second year of life. Exclusive breastfeeding (HR for first Giardia detection in a monthly surveillance stool sample, 0.46 [95% confidence interval (CI), 0.28-0.75]), higher socioeconomic status (HR, 0.74 [95% CI, 0.56-0.97]), and recent metronidazole treatment (risk ratio for any surveillance stool detection, 0.69 [95% CI, 0.56-0.84]) were protective. Persistence of Giardia (consecutive detections) in the first 6 months of life was associated with reduced subsequent diarrheal rates in Naushahro Feroze, Pakistan but not at any other site. Giardia detection was also associated with an increased lactulose/mannitol ratio. Persistence of Giardia before 6 months of age was associated with a -0.29 (95% CI, -0.53 to -0.05) deficit in weight-for-age z score and -0.29 (95% CI, -0.64 to 0.07) deficit in length-for-age z score at 2 years.Conclusion: Infection with Giardia occurred across epidemiological contexts, and repeated detections in 40% of the children suggest that persistent infections were common. Early persistent infection with Giardia, independent of diarrhea, might contribute to intestina

Determinants of campylobacter infection and association with growth and enteric inflammation in children under 2 years of age in low-resource settings

Campylobacter species infections have been associated with malnutrition and intestinal inflammation among children in low-resource settings. However, it remains unclear whether that association is specific to Campylobacter jejuni/coli. The aim of this study was to assess the association between both all Campylobacter species infections and Campylobacter jejuni/coli infections on growth and enteric inflammation in children aged 1-24 months. We analyzed data from 1715 children followed from birth until 24 months of age in the MAL-ED birth cohort study, including detection of Campylobacter species by enzyme immunoassay and Campylobacter jejuni/coli by quantitative PCR in stool samples. Myeloperoxidase (MPO) concentration in stool, used as a quantitative index of enteric inflammation, was measured. The incidence rate per 100 child-months of infections with Campylobacter jejuni/coli and Campylobacter species during 1-24 month follow up were 17.7 and 29.6 respectively. Female sex of child, shorter duration of exclusive breastfeeding, lower maternal age, mother having less than 3 living children, maternal educational level of \u3c6 \u3eyears, lack of routine treatment of drinking water, and unimproved sanitation were associated with Campylobacter jejuni/coli infection. The cumulative burden of both Campylobacter jejuni/coli infections and Campylobacter species were associated with poor growth and increased intestinal inflammation

Pathogen-specific burdens of community diarrhoea in developing countries: A multisite birth cohort study (MAL-ED)

Background: Most studies of the causes of diarrhoea in low-income and middle-income countries have looked at severe disease in people presenting for care, and there are few estimates of pathogen-specific diarrhoea burdens in the community.Methods: We undertook a birth cohort study with not only intensive community surveillance for diarrhoea but also routine collection of non-diarrhoeal stools from eight sites in South America, Africa, and Asia. We enrolled children within 17 days of birth, and diarrhoeal episodes (defined as maternal report of three or more loose stools in 24 h, or one loose stool with visible blood) were identified through twice-weekly home visits by fieldworkers over a follow-up period of 24 months. Non-diarrhoeal stool specimens were also collected for surveillance for months 1-12, 15, 18, 21, and 24. Stools were analysed for a broad range of enteropathogens using culture, enzyme immunoassay, and PCR. We used the adjusted attributable fraction (AF) to estimate pathogen-specific burdens of diarrhoea.|Findings: Between November 26, 2009, and February 25, 2014, we tested 7318 diarrhoeal and 24 310 non-diarrhoeal stools collected from 2145 children aged 0-24 months. Pathogen detection was common in non-diarrhoeal stools but was higher with diarrhoea. Norovirus GII (AF 5·2%, 95% CI 3·0-7·1), rotavirus (4·8%, 4·5-5·0), Campylobacter spp (3·5%, 0·4-6·3), astrovirus (2·7%, 2·2-3·1), and Cryptosporidium spp (2·0%, 1·3-2·6) exhibited the highest attributable burdens of diarrhoea in the first year of life. The major pathogens associated with diarrhoea in the second year of life were Campylobacter spp (7·9%, 3·1-12·1), norovirus GII (5·4%, 2·1-7·8), rotavirus (4·9%, 4·4-5·2), astrovirus (4·2%, 3·5-4·7), and Shigella spp (4·0%, 3·6-4·3). Rotavirus had the highest AF for sites without rotavirus vaccination and the fifth highest AF for sites with the vaccination. There was substantial variation in pathogens according to geography, diarrhoea severity, and season. Bloody diarrhoea was primarily associated with Campylobacter spp and Shigella spp, fever and vomiting with rotavirus, and vomiting with norovirus GII.Interpretation: There was substantial heterogeneity in pathogen-specific burdens of diarrhoea, with important determinants including age, geography, season, rotavirus vaccine usage, and symptoms. These findings suggest that although single-pathogen strategies have an important role in the reduction of the burden of severe diarrhoeal disease, the effect of such interventions on total diarrhoeal incidence at the community level might be limited
