Abstract

This article describes a project of retrospective conversion in a Nigerian research library where the migration from one software program TINMAN/TINLIB to another – the newly acquired CDS/ISIS was carried out. The paper analyses the step‐by‐step approach taken in carrying out the migration successfully. Reasons for the retroconversion and the method of acquisition of the new software are discussed. Also, the problems emanating from the peculiarities of the software and the practical approach used in solving such problems are discussed in detail. The treatment given to accession numbers, reference materials, books with multiple authors and gifts and donations to the library is highlighted. Also, the benefits of the project to the Development Policy Centre (DPC) and other libraries were discussed. The paper concludes that with the successful migration project of the DPC library, the conditions are favourable for a wider usage of the software in Nigerian libraries.

Abstract

The impact of information technology (IT) on society is tremendous. Globalization of trade, the emergence of information economies, and the growth of the Internet and other global communications networks have recast the role of information systems in managing global corporations. The purpose of this study was to investigate the extent to which personal characteristics such as gender, age, education, income, and experience predict IT managers' job satisfaction in Nigeria. A sample of 360 IT managers selected from business organizations in Nigeria were used for this research. The results of this study suggest that IT managers were satisfied with their job, co‐workers, and supervision, whereas they were dissatisfied with their pay and the promotion system. The results of regression analyses also showed that personal characteristics were significant predictors of job satisfaction.

Abstract

Purpose

The purpose of this article is to demonstrate the application of project management principles to retrospective conversion of a library catalogue and to share the experience with other libraries.

Design/methodology/approach

Presents the case of retrospective conversion involving the conversion of card catalogue records and the serials automation at the Faculty of Engineering and Technology Library of the University of Botswana.

Findings

Highlights project management concepts as a means of managing library projects for the optimum benefit of the institution, staff and patrons.

Research limitations/implications

The project involved the conversion of 10,000 manual records and the automation of 250 current journals.

Practical implications

Identifies constraints such as staffing, training and retraining; equipment malfunction and access to online resources; and conflict of work priorities.

Originality/value

A case study of project management applications in academic libraries. Both projects involved project scheduling, staff training, scheduling of duties, and writing of in‐house manuals, all based on project management principles.

Abstract

A simultaneous equation model is used to estimate export demand and supply functions for US soybeans. Price, income, exchange rate and other effects on exports to four world regions are estimated. Inclusion of export supply relationships have very significant implications for estimated price‐, income‐, and exchange‐rate elasticities of export demand. Results fail to support the usual empirical assumption of infinite supply price elasticity for soybeans.

The purpose of this paper is to examine the dynamics of food insufficiency and its determinants among farming households in Southwestern Nigeria.

Abstract

Purpose

The purpose of this paper is to examine the dynamics of food insufficiency and its determinants among farming households in Southwestern Nigeria.

Design/methodology/approach

A combination of cluster and systematic random sampling was used to select 40 households in each local government area of the selected two states. This gives a total of 160 households per state and 320 households in all for the first data collection. Visiting the same households during the second data collection, only 150 households’ data were useful for analysis. Panel primary data were adopted and they were collected in two periods of late and early rain, respectively, over a period of nine months. Primary data were collected with the aid of a well-structured questionnaire, administered on farming households in the area of study. The needed information was collected through the use of interview schedules/questionnaires.

Findings

The transition of food insufficiency households to food sufficiency indicated a differential of 4.25 percent, and the transition of food sufficiency to food insufficiency a differential of 9.33 percent. During the agricultural harvest season more households moved to food sufficiency status (16 percent), while off season insufficiency status was 25.3 percent. The probability of households escaping food insufficiency is 0.25, and the probability of households entering food insufficiency is 0.38. The study provides evidence of transient and high incidence of food insufficiency.

Originality/value

Past studies of this nature only captured the food insufficiency status of households using a snapshot study. Hence, this study brought in innovation by examining the dynamics of food sufficiency/insufficiency in two periods. Therefore the question this study asks is: can a farm-household be food sufficient over a particular period of time and food insufficient in other time?

Abstract

Purpose

Extant literature highlights the increasing inability of project-based organisations (PBOs) to meet infrastructure client’s expectations, particularly as it concerns the delivery of socio-economic outcomes during the delivery process. Unclear communication channels and poor processing of information especially as it pertains to client’s strategic objectives results in a misalignment of objectives among participating parties. As its central proposition, the purpose of this paper is to hold that unclear communication channels between parties within infrastructure project PBOs affects their degree of internal cohesion hence posing strong challenges to their overall viability.

Design/methodology/approach

Applying the Viable Infrastructure Delivery Systems Model (VIDM); a model premised on the tenets of the Viable Systems Model, this qualitative study proceeds to assess a particular PBO within a developing country to understand its communication and control channels and to identify where gaps likely to affect the internal cohesiveness of the PBO, if any, existed. Whereas semi-structured interviews and project/policy documents were used as data collection tools, data were analysed using pre-set themes.

Findings

According the study’s findings, an absence of a prevalent common identity was observed among the various parties to the PBO. Contractors’ capabilities to deliver on time and to budget based on their expertise remained pivotal within the PBO thus abandoning the attainment of the client’s pre-defined socio-economic objectives. Cases of faulty and ineffective organisational architecture, functional and communication issues were observed.

Research limitations/implications

Based upon these findings, it is recommended that the VIDM be adopted at the commencement of the PBO lifecycle and used at various intervals by project managers and other stakeholders for assessing the levels of organisational viability.

Originality/value

The methodology and findings resulting from this study represent information from fieldwork conducted by the author and as such have not been used elsewhere.

Abstract

Purpose

The purpose of this paper is to examine the potential effects of the intake of fermented milk containing the probiotic bacteria Lactobacilli spp. and Befidobacteria sp. as a supplementation for daily food and the possible prevention of hepatic lesions induced by the oral administration of a carcinogenic mutagen 3 amino‐I methyl‐5H‐pyrido (4, 3‐b) indole.

Design/methodology/approach

In total, 20 mice were divided into four groups. A control group was fed the murine pallet food for 30 days. Another three groups were given orally one dose of the toxic mutagen at the beginning of the experimental period and then fed the normal diet. At the 15th day, mice of the first group were dissected while the mice of the second group were given a second dose then continued feeding normal diet. Animals of the third group were given the second dose of the toxic mutagen and started feeding fermented milk for another 15 days. The quality of life was measured by specific strain count in stool, histopathological, histochemical changes of liver and count of lymphocytes were studied.

Findings

The variable count of Lac. sp. and Bif. sp. in stool of mice indicated that feeding these mice on the fermented milk repaired the slightly damaged areas and prevented the progressive damage effects of the toxic mutagen in these areas, while those which were severely damaged remained unrepaired. Moreover, the presented histochemical study recorded slight depletion in the total carbohydrate and total protein contents only in group C in comparison with controls.

Originality/value

The paper shows that the potential effect of fermented milk ingestion was capable of endorsing protective measures to hepatic tissue architecture and decreasing the toxic effect induced by mutagen administration.

– This paper aims to focus on the effect of fermentation on wheat-chickpea-rice weaning blend.

Abstract

Purpose

This paper aims to focus on the effect of fermentation on wheat-chickpea-rice weaning blend.

Design/methodology/approach

Wheat, chickpea, and rice were blended and fermented with Rhizopus koji for 60 h at 29±2°C at an interval of 15 h. Blends were analyzed using methods reported in the literature for physicochemical and sensory properties.

Findings

Protein content of the weaning blends increased progressively from 14.63 percent in the unfermented to 20.89 percent after 60 h of fermentation, while the fat content decreased as fermentation time increases. The pH of the samples gradually decreased from 4.53 to 3.83 with gradual increase in titratable acidity as fermentation time increases. The water absorption capacity, total plate count, and yeast and mold count were found to be in the range 112.2±1.16 to 171±1.67 percent, 1.0×103 to 1.3×103 cfu/g, and 700 to 800 cfu/g, respectively. In terms of sensory analysis, 15-h fermented sample was found to be the best.

Originality/value

The paper has demonstrated effect of fermentation on wheat-chickpea-rice weaning blend.

The purpose of this paper is to evaluate the protective effect of natural fermented milk (NFM) against liver cancer.

Abstract

Purpose

The purpose of this paper is to evaluate the protective effect of natural fermented milk (NFM) against liver cancer.

Design/methodology/approach

Five types of NFM were collected from different places around Makka. The natural flora which present in them were studied and certain types which contain Lactobacillus spp. and Bifidobacterium spp. strains were selected to be used in the research. The nutritional experiment was carried out on 20 Albino mice divided into four groups. The first group (A) was control (not fed on NFM). The second (B) and third (C) groups were fed daily on (NFM) for two weeks. The final group (D) received basal diet only for four weeks, but after two weeks the third and fourth groups were treated orally by one dose of toxic mutagen (0.25 mg/mouse). The quality of life was measured by: specific strain count in stool; histopathological and histochemical studies on liver; and lymphocytic count.

Findings

Cow's milk which contains Lactobacillus spp. and Bifidobacterium spp. has a protective effect depending on its anti‐microbial properties. Also it enhances the endogenous intestinal probiotic bacteria that have several beneficial effects (i.e. detoxification and antigen toxicity) and stimulation of immune modulator cells.

Originality/value

The paper evaluates the protective effect of natural fermented milk (NFM) against cancer of the liver.
