Abstract

For more than a decade now, Nigeria has been witnessing a continuous improvement and boom in theapplication of Information and Communications Technology in all the vital sectors of her economy. Thereis an increasing dependency on computer programs for critical infrastructures, business processes andoperations. This boom is not abating, and is resulting in a corresponding increase in the number ofcompanies and individuals who join an increasing population of software engineers, enterprise applicationdevelopers and programmers. But regrettably, the boom has given rise to a host of ethical issues. Theability to make sound ethical judgement and decision is becoming very important as “half-baked” softwaredevelopers produce critical software that are supposed to run critical business functions and operations. Tocompound this problem the few technical schools or colleges that produce the very needed programmersand web designers do not have a clue that there is something negative creeping in from another angle;they do not have qualified or versed instructors to arm their graduates with the basic foundationknowledge in software professional ethics which is needed to effectively practise the art of softwareengineering in the society at large.This paper investigates the state of software engineering ethics in theface of Nigeria’s upwelling Information and Communications Technology and intention to produce and uselocally designed and implemented software. The paper calls attention to the nonchalance, dispassion andmass negligence attendant to this issue. It further highlights and calls for adherence to sound ethics at alllevels of software production in the Nigerian society at large. The paper uses a case-study and scenario toillustrate how to start doing so.

Abstract

This study was aimed at determining the physico-chemical properties of rainwater collected from a cementfactory and its environment. Four (4) locations labeled A, B, C and D were sampled and analysed. Theresult of the rainwater analysed indicated that locations A, B, C and D had temperature values of 22.3,21.7, 23.5, and 21.8oC respectively, Turbidity; (0.15, 0.18, 0.20 and 0.13 NTU), pH: (6.5, 6.4, 6.1, and 6.7),Hardness as CaCO3: (40.00, 40.00, 40.00 and 40.33 mg/L), NO3- : (36.77, 38.63, 32.40, and 30.20mg/L)respectively, while the microbiological assay showed no presence of e. coli. CO2 values were 24.00, 21.00,22.67, and 24.33 mg/L for A, B, C and D respectively, Ca2+: (21.33, 22.00, 120.33 and 19.67mg/L), SO42- :(10.67, 8.67, 32.67 and 12.67 mg/L) respectively for A, B, C and D. The pH values showed that rainwaterfrom all the locations were slightly acidic particularly location C. Overall, the water was found fit fordrinking though with a relative high amount of Nitrates in samples A and B and a high CO2 contentespecially in locations D, A and C. These results are indications that the area could experience acid rainunder extreme conditions.

Abstract

Regular access to genetically superior bulls from an open nucleus breeding system is an impetus forN’Dama cattle utilization and conservation. However, shortage in the number of bulls that could bedistributed to the farmers for subsequent breeding remains a challenge in some countries of West Africa. Inthis regard, the potential benefit of artificial insemination (AI) and the roles of national policy was assessed.The open nucleus breeding scheme of International Trypanotolerance Center (ITC) in the Gambia was usedas a case study and the research questions were answered with literature review, focus group discussion,and Likert-scale questionnaire. Introduction of AI into the breeding scheme of N’Dama cattle can createhigher selection intensity and promote a wider dissemination of genetic gain made at the nucleus. Withimproved AI techniques, a better use of improved N’Dama bulls can be achieved. Notwithstanding, thereare concerns about low pregnancy rate, quality of the semen, inadequate knowledge of AI technicians, andthe regular availability of quality bulls. For the Gambian national policy, the environmental component isthe most relevant for conservation of N’Dama cattle. This can be buttressed with more flexibility and aclearer communication of the objectives through workshops and local media.

Abstract

The essential theme of this paper is to highlight the condition of health and hygiene in the British Bengalfrom the perspective of official documents and vernacular writings, with special emphasis on the journalsand periodicals. The fatal effects of the epidemics like malaria and cholera, the insanitary condition of therural Bengal and the cultivated indifference of the British Raj made the lives of the poor natives miserableand ailing.The authorities had a tendency to blame the colonized for their illiteracy and callousness whichbecame instrumental for the outbreak of the epidemics. On the other, in the late 19th and the beginning ofthe 20th, the vernacular literature played the role of a catalyst in awakening health awareness, highlightingthe issues related with ill-health, insanitation and malnourishment. More importantly, it became an activelink between the society and culture on the one hand, and health and people on the other. The presentresearcher wants to highlight these opposite trajectories of mentalities with a different connotation. Theideologies of the Raj and the native political aspirations often reflected in the colonial writings, where theyear 1880 was considered as a landmark in the field of public health policies. On the other, the dichotomybetween the masters and the colonized took a prominent shape during 1930s.Within these fifty years; thehealth of the natives witnessed many upheavals grounded on the social, economic and cultural tensions.

Abstract

The aim of this study is to point out that Homer’s epics create a feminine typology that is approached indifferent life situations, in times of peace or war, a typology that will begin, in pure or hybrid forms, a realtradition in the heroic literature: the Demeter-type woman, the Aphrodite-type woman and the Amazontypewoman. If in The Odyssey women act as epic agents and are present in large numbers, in Homer’s firstepic they are backstage characters, but still relevant at the fictional level, because they play a great varietyof roles. The Odyssey reveals femininity from the point of view of man, who compares and assimilates ordifferentiates various types of women. The Iliad offers a heroic perspective on femininity: a woman whostirs the warrior attitude, a woman who accompanies the hero, a woman who engages herself in acompetition against the hero.
