Agile software development practices in Egypt SMEs : a grounded theory investigation

Agile information system development methods have been adopted by most software development organizations due to their proven benefits in terms of flexibility, reliability, and responsiveness. However, companies face significant challenges in adopting these approaches. Specifically, this research investigates challenges faced by software development companies in Egypt while transitioning to Agile. As little previous research is available targeting their concerns, we have conducted a grounded theory investigation. Key problem areas were found including lack of cadence in sprints planning, inadequate use of effort estimation and product quality issues. The developed grounded theory reflects on the key problem areas found with SMEs adopting agile practices and can be used by software development practitioners adopting agile methods in Egypt or similar developing countries as an outline for the common problem areas they are expected to find

How Mistimed and Unwanted Pregnancies Affect Timing of Antenatal Care Initiation in three Districts in Tanzania

Early antenatal care (ANC) initiation is a doorway to early detection and management of potential complications associated with pregnancy. Although the literature reports various factors associated with ANC initiation such as parity and age, pregnancy intentions is yet to be recognized as a possible predictor of timing of ANC initiation. Data originate from a cross-sectional household survey on health behaviour and service utilization patterns. The survey was conducted in 2011 in Rufiji, Kilombero and Ulanga districts in Tanzania on 910 women of reproductive age who had given birth in the past two years. ANC initiation was considered to be early only if it occurred in the first trimester of pregnancy gestation. A recently completed pregnancy was defined as mistimed if a woman wanted it later, and if she did not want it at all the pregnancy was termed as unwanted. Chisquare was used to test for associations and multinomial logistic regression was conducted to examine how mistimed and unwanted pregnancies affect timing of ANC initiation. Although 49.3% of the women intended to become pregnant, 50.7% (34.9% mistimed and 15.8% unwanted) became pregnant unintentionally. While ANC initiation in the 1st trimester was 18.5%, so was 71.7% and 9.9% in the 2nd and 3rd trimesters respectively. Multivariate analysis revealed that ANC initiation in the 2nd trimester was 1.68 (95% CI 1.10‒2.58) and 2.00 (95% CI 1.05‒3.82) times more likely for mistimed and unwanted pregnancies respectively compared to intended pregnancies. These estimates rose to 2.81 (95% CI 1.41‒5.59) and 4.10 (95% CI 1.68‒10.00) respectively in the 3rd trimester. We controlled for gravidity, age, education, household wealth, marital status, religion, district of residence and travel time to a health facility. Late ANC initiation is a significant maternal and child health consequence of mistimed and unwanted pregnancies in Tanzania. Women should be empowered to delay or avoid pregnancies whenever they need to do so. Appropriate counseling to women, especially those who happen to conceive unintentionally is needed to minimize the possibility of delaying ANC initiation.\u

Fasciolosis: Prevalence, financial losses due to liver condemnation and evaluation of a simple sedimentation diagnostic technique in cattle slaughtered at Hawassa Municipal abattoir, southern Ethiopia

This study was carried out from November 2007 to April 2008 to determine the prevalence of fasciolosis and costs incurred due to liver condemnation and evaluate the sensitivity of direct sedimentation method for diagnosis of fasciolosis in cattle slaughtered at Hawassa Municipal abattoir. A total of 3251 adult indigenous cattle were slaughtered at the abattoir during the study period, of which 931 animals (28.63%) were found to be positive for fasciolosis. There was a statistically significant (χ2 = 33.10; p = 0.004) variation in prevalence between the study months where the highest (35.6%) and lowest (21.03%) prevalence were recorded in February and April, respectively. Fasciola hepatica (58.9%) was the predominant fluke identified compared to F. gigantica (10.6%). Mixed infections by both species and unidentified immature flukes were detected in 14.7% and 15.8% of the affected livers, respectively. The mean fluke burden in the affected livers was 55 flukes per liver. As to the severity of infection, 36.63%, 52.31% and 11.06% were lightly, moderately and severely affected, respectively. Moderately affected livers showed the highest mean fluke count (69 ± 1.91) followed by severely (48 ± 1.71) and lightly affected ones (25 ± 1.75) signifying the presence of acquired resistance and local tissue reaction as chronicity of infection supervenes. Taking liver examination as gold standard for diagnosis of fasciolosis, the sensitivity of the direct sedimentation technique was found to be 67.13% and the specificity 100% with substantial agreement (k = 0.74) between the two methods. The financial loss due to liver condemnation was estimated to be 106,400 Ethiopian birr (8312.5 USD) per annum. In conclusion, the observation of such a level of infection in the dry season, high fluke pathogenicity and substantial financial loss associated with condemnation of infected livers warrants the institution of appropriate control measures.

Cryptosporidium in Calves, Lambs and Kids at Haramaya, eastern Ethiopia

A cross sectional study was carried out from November 2010 to April 2011 to determine the prevalence of Cryptosporidium in calves, lambs and kids and to assess potential risk factors in Haramaya, eastern Ethiopia. Hence, fecal samples from a total of 237 study animals (133 calves, 63 lambs and 41 kids) were tested with Sheather’s flotation technique and Modified Ziehl-Neelsen Staining. Accordingly, the overall prevalence was found to be 23.6% (56/237) with the prevalence of 27.8% (37/133) in calves, 22.2% (14/63) in lambs and 12.2% (5/41) in kids. The prevalence of Cryptosporidium significantly (p = 0.047) varied with species of study animals being three times higher likelihood of occurrence in calves compared to its chance of occurrence in kids (OR = 2.8, 95%CI = 1.0, 7.6). No significant difference in prevalence was observed between kids and lambs. The occurrence of the disease was also assessed among the species of animals by taking into consideration different demographic characteristic of the animals including breed, age and sex. For caprine, the prevalence was higher in the cross breed animals (28.6%) followed by the breed of Hararge highland (25%) with no report of the disease in Boer and Ogaden breeds. In ovine, no association was observed between the infection occurrence and the potential risk factors. Analysis of the risk factors in bovine revealed a significant (p = 0.044) difference in disease occurrence among age groups with almost three times more likelihood of the disease occurrence in calves under 3 months than older age category(OR = 2.9, 95%CI = 1.0, 8.2). In conclusion, this study demonstrated the importance of Cryptosporidium in young ruminants with a higher prevalence among calves than lambs and kids.Key words: Cryptosporidium; Prevalence; Risk Factors; Calves, Lambs, Kids, Haramaya, Ethiopi

Registration of ‘NE05548’ (Husker Genetics Brand Panhandle) Hard Red Winter Wheat

Western Nebraska wheat producers and those in adjacent areas want taller wheat (Triticum aestivum L.) cultivars that retain their height under drought for better harvestability. ‘NE05548’ (Reg. No. CV-1117, PI 670462) hard red winter wheat was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in January 2014 by the developing institutions. NE05548 was released primarily for its superior performance under rainfed conditions in western Nebraska and adjacent areas of the Great Plains and its tall plant stature. NE05548 was selected from the cross NE97426/NE98574 made in 1999 where the pedigree of NE97426 is ‘Brigantina’/2*‘Arapahoe’ and the pedigree of NE98574 is CO850267/‘Rawhide’. The F1 generation was grown in the greenhouse in 2000, and the F2 to F3 generations were advanced using the bulk breeding method in the field at Mead, NE, in 2001 to 2002. In 2003, single F3–derived F4 head rows were grown for selection. There was no further selection thereafter. The F3:5 was evaluated as a single four-row plot at Lincoln, NE, and a single row at Mead, NE, in 2004. In 2005, it was assigned the experimental line number NE05548. NE05548 was evaluated in replicated trials thereafter. It has excellent winter survival, acceptable disease reactions to many of the common diseases in its target area, and acceptable end-use quality for bread making

Bovine Tuberculosis Prevalence Survey on Cattle in the Rural Livestock System of Torodi (Niger)

BACKGROUND: Bovine tuberculosis (BTB) is a widespread zoonosis in developing countries but has received little attention in sub-Saharan Africa, especially in Niger. Recent investigations confirmed the high incidence of the disease in cattle slaughtered in an abattoir in Niamey. The fact that most of the animals in which M. bovis has been identified were from the rural area of Torodi implied the existence of a probable source of BTB in this region. This study aimed to determine the prevalence of BTB infection in cattle and to identify risk factors for infection in human and cattle populations in Torodi. METHODS AND PRINCIPAL FINDINGS: A survey was carried out at the level of households keeping livestock (n = 51). The questionnaire was related to the potential risk factors and the presence of clinical signs of TB both in animals and humans. Comparative Intradermal Tuberculin Test was conducted to determine the TB status in cattle (n = 393). The overall apparent individual animal prevalence of tuberculin reactors was 3.6% (CI: 95%, 1.9-5.9), whereas the individual true prevalence was estimated at 0.8% (CI: 95%, 0.0-5.0). Using a multivariate logistic regression analysis and a classification tree analysis, the only household level risk factor that significantly influenced the presence of BTB in cattle was the presence of animals coughing in the herd (OR = 4.7, 95% CI: 1.12-19.71, p-value = 0.034). The lack of the practice of quarantine was borderline significant (OR = 4.2, 95% CI: 0.96-18.40, p-value = 0.056). CONCLUSION/SIGNIFICANCE: The study confirmed that BTB is endemic in cattle in Torodi and the risk of the transmission of the disease to humans is potentially high. For the control of the disease in livestock, slaughtering of infected animals and the compensation of the owners is needed. Collaboration between the veterinary and the medical sectors, in the diagnosis, monitoring, prevention and control of BTB is strongly encouraged

Access to Water Source, Latrine Facilities and Other Risk Factors of Active Trachoma in Ankober, Ethiopia

Objective: This study aims to determine the prevalence and correlates of active trachoma in Ankober, Ethiopia. Methods: A cross-sectional community-based study was conducted during July 2007. A total of 507 children (ages 1–9 years), from 232 households were included in the study. All children were examined for trachoma by ophthalmic nurses using the WHO simplified clinical grading system. Interviews and observations were used to assess risk factors. Logistic regression procedures were used to determine associations between potential risk factors and signs of active trachoma. Results: Overall, the prevalence of active trachoma was found to be 53.9 % (95%CI 49.6%–58.2%). Presence of fly-eye (fly contact with the eyelid margin during eye examination) (Odds Ratio (OR) = 4.03 95 % CI 1.40–11.59), absence of facial cleanliness (OR = 7.59; 95%CI 4.60–12.52), an illiterate mother (OR = 5.88; 95%CI 2.10–15.95), lack of access to piped water (OR = 2.19; 95%CI 1.14–6.08), and lack of access to latrine facilities (OR = 4.36; 95%CI 1.49–12.74) were statistically significantly associated with increased risk of active trachoma. Conclusion: Active trachoma among children 1–9 years of age in Ankober is highly prevalent and significantly associated with a number of risk factors including access to water and latrine facilities. Trachoma prevention programs that include improved access to water and sanitation, active fly control, and hygiene education are recommended to lower the burde

A post-colonial analysis of agile software development methods in ICT4D

There is evidence that agile approaches to information system development can improve product quality and developer productivity. However, successful adoption of these approaches appears to depend on adaptation to specific contexts. This research contributes to a broader goal to understand what it means to “be agile” in the presence of adaptations to the specific context. To pursue our research objectives, we have performed 31 semi-structured recorded and transcribed practitioner interviews from three companies in Lebanon. The interview transcripts were analysed using an approach informed by grounded theory. Agile methods enable learning and improvement through team conversations. Yet, the practitioners in our study shun public self-evaluation, finding it difficult to discuss areas for improvement in public. We also found legacy “top down” management practices that undermine team autonomy and local client companies lack experience of engaging with agile processes. In a more positive vein, we found evidence of rich use of various communications channels to overcome geographical distance. On the one hand, agile methods represent a “northern” idea being propagated to the Global South. And yet, on the other hand, the agile concept of self-organising teams has the potential to be empowering and emancipatory. Post-colonial theory helps us understand the phenomenon of agile tailoring, where development process ceremonies are adapted to suite a specific local context
