Management Awareness and Strategies for the Contemporary African Manager of Organizations

This paper addresses a topical issue: management awareness and strategies for the contemporary African manager. The overall aim of the work is to provide a framework for improved management practices for the manager and the intervener in both private and public sectors. This frame-work is not limited to the African manager but has a wider application for other managers of organizations. In pursuant of this objective, relevant key management concepts are explored and discussed bearing in mind that the subject of management is a dynamic and universal phenomenon. Emphasis is placed on the features of the endowed person and the potentials of the human being as the manager and as the most effective contributor to organizational life.The identified concepts and their properties are interwoven. Other highlights are: (i) the universality in the applications or practices of management; (ii) the peculiarity in the applications and practices of management in different environments or social settings; (iii) management practices, problems and prospects in the African settings (See Table I). Cases cited and examples drawn are meant inter alia to strengthen the objectives of the study

The Puzzling Collapse of Electronic Sliding Friction on a Superconductor Surface

In a recent paper [Phys. Rev. Lett. 80 (1998) 1690], Krim and coworkers have observed that the friction force, acting on a thin physisorbed layer of N_2 sliding on a lead film, abruptly decreases by a factor of ~2 when the lead film is cooled below its superconductivity transition temperature. We discuss the possible mechanisms for the abruptness of the sliding friction drop, and also discuss the relevance of these results to the problem of electronic friction.Comment: 5 pages, no figure

From the ground up: Impacts of a pro-poor community-driven development project in Nigeria

"The community-driven development (CDD) approach has become increasingly popular because of its potential to develop projects that are sustainable, are responsive to local priorities, empower local communities, and more effectively target poor and vulnerable groups. The purpose of this study is to assess the impacts of Fadama II, which is a CDD project and the largest agricultural project in Nigeria. This study used propensity score matching (PSM) to select 1728 comparable project beneficiaries and non-beneficiaries. The study also used double difference methods to compare the impact indicators. Our results show that Fadama II project succeeded in targeting the poor and women farmers in its productive asset acquisition component. Participation in the project also increased the income of beneficiaries by about 60 percent, which is well above the targeted increase of only 20 percent in the six year period of the project. Regarding rural infrastructure investments, we found that the Fadama II project had positive near-term impacts on beneficiaries' access to markets and transportation costs, although the study revealed surprising effects on beneficiaries' commercial behavior and statistically insignificant impacts on nonfarm activities. We also observed that Fadama II increased the demand for postharvest handling technologies but did not have a significant impact on the demand for financial management and market information. Fadama II reduced the demand for soil fertility management technologies. The decline likely reflects the project's focus on providing postproduction advisory services and suggests the need for the project to increase its support for soil fertility management and thus limit the potential for land degradation resulting from increased agricultural productivity. Overall, the Fadama II project has achieved its goal of increasing the incomes of the beneficiaries in the first year of its operation. The project has also succeeded in targeting the poor and vulnerable in its productive-asset component, even though that did not appear to increase significantly short-term household incomes among the poorest asset tercile. The unique feature that could have contributed to the significant impact of the project in a short time is its broad-based approach, which addresses the major constraints limiting the success of CDD projects that address only one or two constraints. This has implications on planning poverty reduction efforts in low-income countries. Given that the poor face numerous constraints, a CDD project that simultaneously addresses many constraints will likely build synergies that will lead to larger impacts than will a project that addresses only one or two constraints. This suggests the need for the government and donors to pool resources and initiate multipronged CDD projects rather than many isolated projects." from Author's AbstractCommunity driven development, Poverty reduction, Propensity score matching, Difference-in-difference, Fadama,

Partial Purification and Kinetic Properties of Polygalacturonase from Solanum macrocarpum L. Fruit

Background and Objective: Polygalacturonase [Poly (1, 4-"-D-galacturonide) glucanohydrolase, E.C 3.2.1.15] is a subclass of pectinase that hydrolyzes the glycosidic linkages between galacturonic acid residues in polygalacturonans. Solanum macrocarpum ripening prompts pectinase production. The objective of this study was to examine the kinetic properties of polygalacturonase from Solanum macrocarpum L. fruit. Methodology: The enzyme was partially purified by ammonium sulphate precipitation and gel filtration. Protein content, polygalacturonase activity and kinetic parameters were determined. Results: The protein content and polygalacturonase activity of the fruit juice extracts were 0.63±0.02 mg mLG1 and 45.96±6.31 U mgG1 protein, respectively. A 1.7 and 108.3 fold increase in enzyme activity was achieved by ammonium sulphate precipitation and gel filtration, respectively. The enzyme had a Vmax of 76.92 unit mgG1 protein and Km of 0.92 mg mLG1. The pH profile of the enzyme showed three activity peaks at 3.0, 5.5 and 7.0. The enzyme was most active at pH 3.0 and showed optimal activity at 30EC. Rapid release of product was observed within the first 20 min of enzyme incubation. The Zn2+, Ca2+, Mn2+, Pb2+, Fe2+, Cu2+ and EDTA exhibited inhibitory effect on polygalacturonase activity whereas Mg2+ had stimulatory effect on the enzyme. Conclusion: It was concluded that the fruit of Solanum macrocarpum is a rich source of polygalacturonase. The enzyme is favourably comparable with that of a fungi source and could be further exploited for commercial production of the enzym

The Role of Business Strategy in Accomplishing Organization Mission in Nigerian Manufacturing Companies

The imperativeness of strategic alignment in attaining organizational objectives have become critical in this contemporary business age. The study examined the role of Business Strategy on Mission Accomplishment of Manufacturing companies with a major focus on mission statements of two multi-national companies in Nigeria. Probability and non probability sampling techniques were adopted. In the first stage, the two multinational companies were purposively selected among the list of registered manufacturing companies while in the second stage, a simple random sampling procedure was employed to draw participants from the organizations. A total sample of 384 participants was planned by the sampling procedure, however, only 291 participants were successfully interviewed. From the analysis, it was asserted that the employment of business strategy enhances organizational mission irrespective of the type, ownership, management and size of the organization. In addition, there is need for a thorough environmental scanning in order to select the appropriate business strategy to be adopted in accomplishing the specific aspect of the organization`s mission

Does integration of HIV and SRH services achieve economies of scale and scope in practice? A cost function analysis of the Integra Initiative.

OBJECTIVE: Policy-makers have long argued about the potential efficiency gains and cost savings from integrating HIV and sexual reproductive health (SRH) services, particularly in resource-constrained settings with generalised HIV epidemics. However, until now, little empirical evidence exists on whether the hypothesised efficiency gains associated with such integration can be achieved in practice. METHODS: We estimated a quadratic cost function using data obtained from 40 health facilities, over a 2-year-period, in Kenya and Swaziland. The quadratic specification enables us to determine the existence of economies of scale and scope. FINDINGS: The empirical results reveal that at the current output levels, only HIV counselling and testing services are characterised by service-specific economies of scale. However, no overall economies of scale exist as all outputs are increased. The results also indicate cost complementarities between cervical cancer screening and HIV care; post-natal care and HIV care and family planning and sexually transmitted infection treatment combinations only. CONCLUSIONS: The results from this analysis reveal that contrary to expectation, efficiency gains from the integration of HIV and SRH services, if any, are likely to be modest. Efficiency gains are likely to be most achievable in settings that are currently delivering HIV and SRH services at a low scale with high levels of fixed costs. The presence of cost complementarities for only three service combinations implies that careful consideration of setting-specific clinical practices and the extent to which they can be combined should be made when deciding which services to integrate.
