respective themes and backed up by evidence from the literature reviewed. This means, the analysis followed thoroughly the pattern-matching method before deductions and conclusions were drawn from the findings. 3.13 Limitation of the Study There are some limitations which in one way or another had affected the execution of this study. Time oneof such limitatitons, as it is the most scarce and resource in a time-bound research such as this one. In this stdy, time was limited as the the researcher was required to finish within a definite period and fulfil the requirments of the PhD study. Moreover, the researcher had to collect the required data, process the data and analyse the data within the allotted period. It is this time constraint, which limitated the extent to which the study was conducted in the study area. Financial constraints were another limitation in the study. The researcher di not have ample funds for the reaserch as the sponsorship under HESLB was limited and the research funding severely curtailed. The researcher had to deploy own additional resources to recruit the research assistants required to facilitate the completion of the study. The little funding available was wisely and prudently applied for the successful completion of the research in Kawe ward. Despite these limitations and challenges, the study was successfully conducted to its logical conclusion.
3.14 Ethical Consideration Research ethical considerations include anonymity and informed consert, conflict of interest and the art of ethical judgement (Salkind, 2010).A brief elaboration is provided below for further understanding of the ethical issues. 3.14.1Research Clearance The research is a process which involves various procuderes aimed at accomplishing the set objectives. In this regard, various ethical issues were taken into consideration for the successful completion of the research process.The art of ethical judgement requires the researcher to comply with the research protocol by complying with the various guidelines applicable to the research in question such as official clearance or permission in form letters for ethical asssessment(Salkind, 2010). Thus, before going for fieldwork the researcher sought the permission from the respective authorities for carrying out research,and research clearance was granted, which included the Open University of Tanzania research clearance and clearance from the RAS office. Such formalisation and clerance paved way for getting clearance at a more local level from the DAS office at the Kinondoni Municipal Council. Local government leaders were also consulted and informed about what was the research all about. The question of the the art of ethical judgement further requires the evaluation of scientific findings in a combination of interpretive ability and seasoned reflection. Moral judgement, on the other hand, requires the ability to evaluate critically supporting arguments. In this aspect, the researcher took into account by linking the
