Applications Of Weak Ion Association Between Symmetrical Tetraalkylammonium Ions And Inorganic Anions, Julius Mbuna
Applications Of Weak Ion Association Between Symmetrical Tetraalkylammonium Ions And Inorganic Anions, Julius Mbuna
Journal of Humanities and Social Sciences
Interactions between tetraalkylammonium ions and inorganic anions can be used to develop methods of separation for inorganic anions by any separation technique. From the ion association and thermodynamic data, capillary electrophoretic (CE) technique can be easily designed to effect separation of inorganic anions samples. Using CE mode such as capillary zone electrophoresis (CZE) to investigate weak ion association between inorganic anions and the pairing cations also furnishes data to evaluate association theories like Bjerrum’s theory. Findings show that the increase in association constant Kass as the dielectric constant decreased is not exponential as maintained by the Bjerrum’s theory. The increase …
Vowel Harmony In Kuria, Mary Zacharia Charwi
Vowel Harmony In Kuria, Mary Zacharia Charwi
Journal of Humanities and Social Sciences
This paper describes vowel harmony in Kuria, an Eastern Bantu Language spoken in Tanzania and Kenya. It is indicated that Kuria has seven vowels which are contrastive in length, and which are not freely distributed. Two types of vowel harmony are explained, namely ‘the stem controlled vowel harmony’ and ‘the dominant vowel harmony’, each of which could be progressive or regressive. The paper also shows the distribution of Kuria vowels in nominal prefixes and pre-prefixes. Essentially long vowels can occur in any position but not in initial and final positions. The phonological processes that affect Kuria vowels are also accounted …
Accounting Information Systems And Governance Issues In Local Government Authorities In Tanzania, Henry Chalu, Severine S. Kessy
Accounting Information Systems And Governance Issues In Local Government Authorities In Tanzania, Henry Chalu, Severine S. Kessy
Business Management Review
Among the strategies identified by MKUKUTA to improve good governance in Local Government Authorities (LGAs) in Tanzania are those concerned with strengthening financial management, accounting, financial reporting, auditing and budgeting. The opinion is that strengthening those processes requires an effective accounting information system (AIS). Therefore this study had two aims; first to explore the role played by AIS in promoting accountability, participation, predictability and transparency; and second to identify factors influencing the effectiveness of AIS in fulfilling those roles. To achieve these objectives, the data analysed were collected from four LGAs through 23 interviews, 3 focus group discussions and documentary …
Transformation Of Non-Governmental Micro Finance Institutions (Mfis) In Tanzania, Marcelina Mvula Chijoriga
Transformation Of Non-Governmental Micro Finance Institutions (Mfis) In Tanzania, Marcelina Mvula Chijoriga
Business Management Review
Transformation of NGO micro finance institutions (MFIs) is one of the solutions for increasing the supply of financial services to micro and small enterprises and the rural poor. The findings revealed that there are a number of challenges affecting the transformation of MFIs, including the lack of human resource capacity; inadequate technical skills in banking and finance; the lack of demand-driven financial products; limited capital and loanable funds; weak ownership and governance structures; and poor information technology systems including poor loan tracking. The legal and regulatory framework and high donor dependence also affects MFIs ' operations as commercial enterprises as …
Performance Of Merged Banks In Tanzania: The Case Of Anc Bank Ltd And Hbc Bank Ltd, Sylvia Shayo Temu, James Andilile
Performance Of Merged Banks In Tanzania: The Case Of Anc Bank Ltd And Hbc Bank Ltd, Sylvia Shayo Temu, James Andilile
Business Management Review
This paper assesses the impact of mergers on the performance of merged banks in Tanzania using the CAMEL model. The study found no compelling evidence to support the assertion that mergers improve banks ' performance as the study had mixed results, both improvement and deterioration in some aspects. It was further observed that post-merger performance is greatly linked to the ability of the banks to strengthen the quality of assets. This is because deterioration in their quality affects both earnings and banks ' capital. The study recommends that banks institute robust risk- management systems to improve their performance in the …
Does A Loan Have An Impact On Attitude To Risk Among Micro-Entrepreneurs In Tanzania?, Onesmo Selejio
Does A Loan Have An Impact On Attitude To Risk Among Micro-Entrepreneurs In Tanzania?, Onesmo Selejio
Business Management Review
Intervention with small loans for micro-entrepreneurs is crucial for the establishment and growth of their businesses. Intervention of this sort, however, induces changes in behaviour and attitude to risk depending on the repayment mechanisms in place. From the entrepreneurial point of view, after obtaining the loan, the borrowing agents are likely to make decisions that are associated with higher risk than would have been otherwise. But the argument is that, if the repayment mechanisms are so draconian, the opposite can occur, making micro-entrepreneurs more risk averse. Such entrepreneurs are likely to maintain the status quo and strive to be able …
Comparing Competitiveness Of Family And Non-Family Smes In Tanzania, Goodluck Charles
Comparing Competitiveness Of Family And Non-Family Smes In Tanzania, Goodluck Charles
Business Management Review
This paper aims at examining competitiveness of family firms in comparison with non-family firms assessing the differences in the strategies applied by the two categories of firms. Using a sample of 341 SMEs, MANOVA was applied to compare competitiveness and the strategies of the firms studied. The findings show that family SMEs are generally more competitive than non-family SMEs in terms of financial indicators. However, in terms of market based-indicators, the difference in competitiveness is insignificant between the two groups of firms. The findings also show that family enterprises have a greater inclination and focus on the longer-term horizon, to …
Correlation Between Morphological, Optical And Electrical Properties Of Zno:Al/Zno Double Layers And The Cu(In,Ga)Se2 Solar Cell Efficiencies, Pd Nsimama
Tanzania Journal of Science
The morphological, optical and electrical properties of magnetron sputtered ZnO:Al/ZnO double layers are reported and their correlations with their respective Cu(In,Ga)Se2 (CIGS) solar cell efficiencies are presented.

Tanzania Journal of Science
The central part of Tanzania, Dodoma, was hit by an Mw= 5.5 earthquake in November 4, 2002. It was part of a swarm of moderate earthquakes that affected the area. This paper, reports the first attempt to investigate significant past earthquakes along one of the known seismically active riftfaults (Bubu fault, Gonga segment) by paleoseimological trenching. The trench revealed over 3 episodes of faulting (2 of which correspond to Mid-Holocene faulting). The magnitude of the largest earthquake illustrated in the trench is estimated at Mw = 6.3-6.4 and the slip rate between two recent faulting events is about 0.11 to …
Plains Gerbils (Gerbilliscus Robusta) As Food Of The Barn Owl (Tyto Alba) In The Serengeti Plains (Tanzania): Thirty-Six Years Later, Rbm Senzota
Tanzania Journal of Science
The barn owl (Tyto alba (Blyth 1862) roosts and nests in crevices and caves of kopjes (rock outcrops) of the Serengeti plains. Its major food in the 1970’s was found to be Gerbilliscus robusta (Cretschmer 1826) which inhabits the expansive grasslands surrounding the kopjes. In October 2012, pellets of the owl were collected from one of its roosting cave in the Gol Kopjes at the plains; the roosting cave was the same as one where a 1976 pellet collection was made. Collected intact and disintegrated pellets were weighed and sorted to identify and enumerate their contents. Morphometrics of sorted out …
Trophy Hunting And Trophy Size In Ugalla Game Reserve, Western Tanzania, P Wilfred
Trophy Hunting And Trophy Size In Ugalla Game Reserve, Western Tanzania, P Wilfred
Tanzania Journal of Science
The present paper explores trends and variations in trophy size among wildlife species hunted in the Ugalla Game Reserve (UGR) of western Tanzania, in relation to hunting success (animals shot species-1 quota-1). Data on trophy hunting from 2006 – 2010 were obtained from the UGR office in Tabora Region. Forty-seven species were targeted by trophy hunters. Hunting success differed significantly across the species (Generalised Linear Model [GLM] with a binomial error structure: deviance chi-square [X2] = 9.64, d.f. = 44, p<0.001). Twenty-eight species had trophy size measurements, but only 6 species had measurements taken consistently throughout the data period. Although most of the shot animals were above their minimum trophy size limits (official trophy limits below which animals could not be removed) there was significant variation among species (GLM with normal errors: F5,201 = 509.12, p<0.001). Time (years) had no significant effect on trophy size, but the trend over time in trophy size differed significantly among species (F5,194 = 5.42, p<0.001). Of the trophy species, greater kudu (Tragelaphus strepsiceros) had the largest mean trophy size, whereas warthog (Phacochoerus africanus) had the lowest trophy size and showed a considerable decline. The majority of the animals had trophy sizes hovering just above their minimum limits. This should be monitored rigorously to avoid removing large numbers of actively breeding animals.

Wet Oxidation Of Maleic Acid By A Pumice Supported Copper (Ii) Shiff Base Catalyst, Jeg Mdoe, Raj Minja, L Daniel
Tanzania Journal of Science
Pumice supported Cu (II) Schiff base catalysts were prepared by surface chemical modification followed by complexation with Cu (II) acetate. The resulting materials were characterised by Diffuse Reflectance Fourier Transform Spectroscopy (DRIFTS) to confirm the modification. The materials were tested in a wet oxidation of maleic acid using air or hydrogen peroxide as an oxidant. Results indicate that up to 80% degradation of maleic acid could be achieved in the presence of the catalyst using hydrogen peroxide as an oxidant. The degradation was found to depend on the type of oxidant, temperature and whether the parent pumice was acid pre-treated …

Young males of Tanzania’s Kuria tribe have long been known to have preference for a career in the armed forces. This paper examines what drives them to choose an army career. The field work for the paper was conducted in Tarime district of the Mara region where Tanzania’s Kuria population is largely concentrated. The analysis is based on the theoretical framework developed by the theory of planned behaviour in terms of which the intention of the individual human actor is …
The Quality Of Education In Tanzania: An Exploration Into Its Determinants, Sam Maghimbi
The Quality Of Education In Tanzania: An Exploration Into Its Determinants, Sam Maghimbi
Journal of Humanities and Social Sciences
Recent rapid expansion in school enrolment at all levels represents a profound challenge to parents and the government in Tanzania. There has been a very high increase in the number of school-going-age children from year to year due to high fertility. Government resources are thinly spread in very many schools, and there is fear that quality of education may be compromised. The paper presents the argument that there is in evidence a government-will-pay (gwp) attitude in the parents’ values. The parents’ contribution to secure improvement in quality of education is not forthcoming because of this belief, which is traced to …

The Role Of Informal Politics In Environmental Governance In East Uluguru Mountains In Tanzania, Christopher Mahonge
Journal of Humanities and Social Sciences
Informal politics exercises a significant influence on formal decision making arrangements although its interplay with formal arrangements has conventionally been ignored. This study investigates how informal politics affects the operationalisation of a formally sanctioned initiative in the sphere of environmental governance. Nyachilo village, situated in the East Uluguru Mountains, was the site of the fieldwork of this study. The establishment of participatory environmental management in this village, through village environmental management committees, aimed at bringing a balance between the twin objectives of environmental conservation and development. However, the two-year experience in the implementation of this community-based environmental management approach has …
Parliamentary Supremacy In Tanzania: Rhetoric And Reality, Frank J. Mateng’E
Parliamentary Supremacy In Tanzania: Rhetoric And Reality, Frank J. Mateng’E
Journal of Humanities and Social Sciences
This paper interrogates the theory and practice of parliamentary supremacy in Tanzania. We examine the assertion that, on becoming independent, Tanzania inherited the doctrine of parliamentary supremacy enshrined in the Westminster model. Using a historical approach, the paper analyzes the relationship between the legislature and the executive branch of government from 1926 to 2010, and concludes that the notion of parliamentary supremacy in Tanzania has remained more rhetorical. In theory the parliament is supreme, but at the level of practice its role has mainly been confined to the law-making and advisory functions with limited scope for the exercise of the …

Collegiality In Teacher Design Teams: Experience From The Netherlands And Tanzania, Ayoub C. Kafyulilo
Journal of Humanities and Social Sciences
Teachers’ collegiality is becoming an increasingly important component of teachers’ professional development programmes that are geared at improving students’ learning. Studies have shown that, through collaboration, teachers can learn from one another and develop professionally. This study investigates the extent to which true collegiality exists in teacher design teams in the Netherlands and in Tanzania. It specifically investigates the ways in which teachers establish collegiality in schools and the influence of education authorities (inspectorates, school management and policy makers) in teachers’ decision making in the design teams. It also investigates how varying interests, values and attitudes of teachers are accommodated …
Case Studies: Developing Critical Thinking In New Teachers, Mark A. Hamilton
Case Studies: Developing Critical Thinking In New Teachers, Mark A. Hamilton
Journal of Humanities and Social Sciences
Critical thinking is increasingly depicted as a crucial component of teaching and learning programmes worldwide, including teacher education. Reflecting the trend toward inquiry-based, constructivist teacher professional development of the past twenty years, definitions and approaches to teaching critical thinking nevertheless vary quite widely. The present article thus discusses the use of case studies as an adaptable, flexible tool for developing critical thinking in student teachers, in ways that reflect their experiences and needs. The article includes sample cases of ‘real world’ situations of practice to show how case-study method can be employed to simulate the kinds of problems, issues and …
Spatial-Temporal Variation In Sex Ratio And Group Size Of Ostriches (Struthio Namelus) In The Serengeti National Park And Environs In Northern Tanzania, Fj Magige
Tanzania Journal of Science
A study was conducted on variation in sex ratio and group size of ostriches (Struthio camelus) in Serengeti National Park and adjacent partially protected areas in northern Tanzania. Data were collected for two years (2005- 2006), along 388 km of roads. The two areas were compared with respect to ostrich sex ratio (male: female) and group size. Seasonal variation of these variables (sex ratio and group size) was also determined. Repetitive sampling showed an overall femaleskewed sex ratio, which was significantly different from unity. The sex ratio inside the National Park was also significantly skewed towards females, whereas that in …
