Challenges faced by female students and the messages conveyed to them by practices of lecturers with regards to sexual harassment. Do lecturers nurture or denature their students?
No full textChallenges faced by female students and the messages conveyed to them
by practices of lecturers with regards to sexual harassment. Do lecturers
nurture or denature their students?is a journal article.The aim of the study was to scrutinize what happens to students in a teacher?s college environment in terms of sexual
harassment. It further sought to provide insights on (I) whether students are sexually harassed by lecturers (ii) the messages
this sends to students (iii) how students cope with such experiences and the values they consequently pick because of such
experiences. The research was located in the interpretive paradigm hence it adopted qualitative approach and used a case
study design. Purposive sampling was used to select three college managers, ten lecturers and twenty five student
participants. Seven of the students were interviewed individually using semi-structured interviews while 18 of them
constituted 3 focus groups of six students each that completed the data collection by interview. The study found that there
was sexual harassment of students by some lecturers in the colleges. The study also established that students got the message
that some lecturers did not value students and on occasion treated them in a degrading manner. The study also established
that students used some strategies to cope including avoidance, appealing to authorities and counselling. The study
recommended that in cases of sexual harassment, specially trained officers in handling sexual harassment cases for reporting
such cases be put in place so that in view of the culture of fear of victimization and stigmatization, students may be forthcoming
in reporting such sensitive and personal matters so that these are curtailed
Potential of Natural Dye Processing in Matabeleland South Province: Case Study of Masendu Ward, Bulilima-Mangwe District, Zimbabwe
No full textThis is a special issue articleSynthetic dyes are non-biodegradable. There is a quest in the dyeing industry to replace these with natural dyes. The availability of raw material is a pre-requisite is assessing the manufacturing of any product. This paper outlines the results of a survey to determine the availability and distribution of natural dye trees in in Zimbabwe?s Bulilima-Mangwe District. Other plant uses are highlighted. Fifty-eight different plant species were identified. Forty one and fifty-nine percent of the plant species are dye and non-dye plants respectively. With improved technology and commercialisation technics, the district will benefit from the natural dye business venture
Glutathione Transferase of Schistoma Mansoni and its Interaction with Praziquantel.
No full textPresented at the Research Day Seminar 1990, University of ZimbabweGlutathione S-transferases play an important role in the excretion of xenobiotics as well as in the antioxidant defence system of cells. The glutathione S-transferase of the parasitic' trematode Schistosoma mansoni has been studied. The results of preliminary experiments are presented here. The pH optimum of the enzyme was found to be 9.5 which is much higher than that of the mammalian liver enzyme. The apparent Km for the substrate 1 chloro 2,4 dinitrobenzene (CDNBL was 1.25 mN and for glutathione was 0.37 roM. The antischistosomal drug Praziquantel was found to inhibit the conjugation of CDNB in a competitive manner. The implications of these results will be discussed
Theoretical Assessment of the Transmission Dynamics of Leprosy
No full textPublished Online February 2013 (http://www.scirp.org/journal/am)Leprosy is a communicable disease which can cause hideous deformities to the afflicted and social stigmatization to them and their families. The continued high endemicity of leprosy in pockets of Sub-Saharan Africa is a source of bafflement to researchers. In this paper, we investigate non-compliant behavior by patients on treatment and possible in-adequacy of the prescribed treatments as the reason for the persistence of the disease in the region. We construct theoretical, deterministic mathematical models of the transmission dynamics of leprosy. These models are modified to en-capsulate non-compliance and inadequate treatment. The models are then analyzed to gain insight into the qualitative features of the equilibrium states, which enable us to determine the basic reproduction number. We also employ analytical and numerical techniques to investigate the impact of non-compliance and inadequate treatment on the transmission dynamics of the disease. Our results show that, as long as there is treatment, leprosy will eventually be eliminated from the region and that the disposition under investigation only serves to slow the rate at which the disease is eradicated.National University of Science and Technology

It is also available at: http://www.ijpcbs.comVariance components for additive direct, additive maternal, permanent environmental effects,the covariance between additive direct and maternal effects were estimated by maximum
likelihood, fitting six animal models from 2341 carcass length pedigree records of indigenous Matebele goats in Zimbabwe. All investigated models included a random direct genetic effect
but different combinations of random 0.49 when the maternal heritability when the maternal genetic effects were included in the model, while h2 estimates were 0.04 and 0.32 when the maternal effects were excluded. The maternal heritability (h2m) was 0.00 when only maternal genetic effects were included in the model and were 0.32 to 0.37 when the permanent environmental effect of the dam was added. The permanent environmental effect of the dam was negligible. The negative covariance between direct and maternal genetic effects of carcass length (?2
am) were observed. Using an Sp statistic comparison, Model 2 which had
additive direct and additive maternal only, excluding the covariance of direct and maternal genetic effects proved to the ?best? among the six models for carcass length evaluation
Capacity and Capacity Utilisation Detailing is critical for business growth
No full textPublished in The Chronicle Newspaper of 2013 on the productivity column.The issue of capacity utilization became a spotlight issue during and after the economic decline
that bedeviled the Zimbabwean productive sector in the years running to 2008. Many figures of
percentage utilization were talked about but did someone stop to say that those really are the
utilization figures that people should be talking about. It is at that point that I feel organizations
and the nation at large should know what capacity they have. This will enhance plans for
economic revival and its associated growth. Having capacity means a connected network of
functional systems that are capable of producing per unit time. The interdependency is also
critical. Hence it is not enough to define capacity by what a single machine or worker can
produce
Lean Manufacturing a strategy for survival to supplement DIMAF
No full textPublished in The Chronicle Newspaper of 2013 on the productivity column.When one talks about World Class Manufacturing (WCM), they cannot avoid mentioning
Lean Manufacturing. It is one of the WCM principles that were developed in order to
minimize if not to eliminate waste in manufacturing. There is current concern in the
nation about the relevance of the Distressed Industries Marginalised Areas Fund (Dimaf).
This has been to date accessed by companies some of which are in the manufacturing
sector. The disbursement has been done in order to facilitate capacity utilization and even
survival for some. Reports coming through are showing that little progress has been made
towards achieving the goal of industrial resuscitation using this route. This may be
because of some underlying causes that are inherent in the industries that need to be
addressed. I mentioned the adopting of World Class Manufacturing Principles in my
earlier article. This article is meant to highlight how the Lean Manufacturing principle
can be used to supplement Government efforts and support effective utilization of the
DIMAF
Transformational Leadership and Business Growth.
No full textPublished in The Chronicle Newspaper of 22 May 2013 on the productivity column.Business organizations in Zimbabwe and Africa at large are under pressure from global
competitive forces. The other dimension that intensifies this pressure is the highly
dynamic environment. In order to attain business growth in such an environment, there is
need for transformational leadership. There is definitely no reason to remain static in a
dynamic environment. If you are not transforming your organization, your competitors
are and they will win at your expense
An analysis challenges faced by Zimbabwean micro finance institutions in providing financial services to the poor and informal sector in the dollarised regime
No full textMicro-Finance Institutions (MFIs) play a pivotal role in the provision of services to the financially excluded population , particularly the poor and the informal sector. The study investigated the reasons behind the collapse and under- performance of MFIs in a dollarized regime. A survey research design was adopted targeting all 17 MFIs in Bulawayo inclusive of those that collapsed. The major finding was that MFIs are facing funding challenges. Most of them use limited personal funds to finance their businesses. In addition, the study also revealed that MFIs have poor corporate governance structures. Management Information Systems (MIS) have not been fully exploited. The major conclusion drawn from the study was that lack of funding is the major factor hindering the growth and development of MFIs in Zimbabwe. The main recommendation was that MFIs must be adequately regulated and be encouraged to have suitable governance structures in order to attract funding
