Ethical managerial orientations: emerging issues

Abstract: It is particularly in times of corporate scandals and moral lapses that the broader public and interest groups in a corporation ask themselves the fundamental question, namely, who are corporate managers and are they ethical. It is only in the recent years that managers and researchers have turned their attention to ethics management. The concern for “ethical consciousness” comes at the time when the concept of leadership legitimacy is questioned and when the public’s trust in corporate governance is extremely low. Leaders ought to be a crucial source of ethical guidance for employees and should at the same time be responsible for moral development in an organization. People might think that ethics is something intimate, a confidential matter that an individual and his conscience share. How we behave, how we reach goals (as long as they are legal and legitimate), might not seem important, and some might even say that ethics has nothing to do with management. The truth is however just the opposite, ethics has a lot if not everything to do with management/leadership, and managers’ behaviour is disseminated throughout the corporations and their behavioural standards are the crucial part of corporate climate, and when stabilized, culture. The purpose of this paper is to examine the issue of managerial ethical orientation. Four distinct orientations were considered in this paper, namely justice orientation, deontological or contractualist orientation, relativism orientation and teleological orientation.

Effect of Fungi Contamination of Two Varieties of Cowpea Sold in Port Harcourt Metropolis

Abstract: The microbial contamination of two cowpea varieties sold in Port Harcourt was investigated. The fungi associated with the grains were isolated by placing the cowpea seeds in sterile Petri dishes containing sizeable cotton wool dampened with 5ml sterile distilled water for seven days to allow for the growth of fungi. Proliferated fungi were later grown on freshly prepared Sabouraud Dextrose Agar plates. Pathogenicity test was carried out by inoculating isolated microbes into healthy cowpea seeds. Three fungi belonging to the genera; Mucor, Aspergillus, and Rhizopus sp were identified. The pathogenicity test showed that the cowpea seeds were infected and the weight reduced drastically. The weight of the cowpea seeds (white) before inoculation was 0.24 ± 0.03. The weight after being inoculated with Mucor sp, Rhizopus sp, and Aspergillus flavus was 0.22 ± 0.12, 0.18 ± 0.09, and 0.25 ± 0.20, respectively. The weight of the cowpea seeds (brown) before inoculation was 0.18 ± 0.05. The weight after inoculation with Mucor sp, Rhizopus sp, and Aspergillus flavus recorded 0.25 ± 0.17, 0.18 ± 0.09, and 0.31 ± 0.12, respectively. The pathogenicity test showed that the microorganisms had effects on the cowpea seeds which was observed in the increased weight of the seeds. Furthermore, the microorganisms isolated in this study could be dangerous to health if proper measures are not taken during preparation.

Production planning and control complementarity architecture in selected manufacturing firms in port harcourt, nigeria

Abstract: The strategic objective of this study is to empirically have an objective grasp of production planning and control complementarity architecture of five selected manufacturing firms and relevant areas of cost control. The paper empirically explores some facets of production planning and processing analysis in different machines and periods; production divisions and types, scheduling and sequencing of production planning. Capacity planning levels including potential capacity, immediate capacity and effective capacity were strategically discussed. Aspects of production control architecture such as dispatching and functions of the dispatcher were also evaluated. Other related areas of production control examined include: expediting (follow-up) and progressing, and the activities in these production and control elements were objectively handled. The study arrived at the fact that, production planning and control functions complement each other in their functionality. Effective scheduling and sequencing are revealed to be a panacea that help the handling of time, space constraints and associated cost elements in production operations management. It is therefore recommended that, production and control operations functions should complement, and be jealously guided in manufacturing operations. Article visualizations:

Physicochemical and Bacteriological Quality of Water from Storage Tanks in a Tertiary Institution in Rivers State, Nigeria

Abstract: Water quality analysis is essential in assessing the suitability of different water sources used for various purposes, including industrial and domestic uses. This study was therefore aimed at determining the physicochemical and bacteriological quality of water samples from different storage facilities in a tertiary institution in Port Harcourt, Rivers State, Nigeria. The study involved eighty (80) water samples obtained from water storage tanks situated at 16 locations within the premises of the institution, to ascertain the physicochemical property, presence and population of different bacterial groups influencing the quality of these water sources. In-situ and ex-situ physicochemical analyses as well as bacteriological investigations were carried out on all samples, using standard laboratory procedures. Results of physicochemical analysis showed that the pH ranged from 4.15±0.14 to 7.16±0.08; conductivity, from 50.55±0.49 (µs/cm) to 364.00±2.83; salinity, from 0.02±0 (ppt) to 0.18±0; temperature, from 27oC to 28oC; Chloride, from 1.03±0.06 (mg/l) to 10.80±0.79; total alkalinity, from 4.00±0 (mg/l) to 11.00±1.41; Dissolved oxygen from 3.04±.020 to 7.36±0.08 (Mg/l) and BOD ranged from 0.81±0 to 4.23±0.09 (Mg/l). Results for bacterial population showed total heterotrophic bacteria ranging from 1.03±1.19 x 103 CFU/ml in water from reservoir tanks at the Faculty of Engineering, to 5.89±2.59 x 103 CFU/ml at Road A Block B; total coliform count ranged from 0 CFU/ml in most samples, to 10.00±2.36 x 102 CFU/ml in Block B reservoir tanks. Water reservoirs in clinic area recorded the highest Salmonella/Shigella counts (1.00±0.23 x 101 CFU/ml) with other stations having zero counts. Hall F (Hostel Ext) on the other hand had the highest counts for Vibrio (2.20±3.01 x 101 CFU/ml). The phenotypic characterization identified Citrobacter spp. as the most occurring (27.27%) bacterial isolate in the study, followed by Alcaligenes faecalis and Klebsiella spp. (18.18% each). Enterobacter spp., Edwardsiella spp., Erwinia psidii, Acinetobacter spp., Pseudomonas spp., Providentia spp. and Salmonella spp. all appeared as the least occurring, having a percentage of 4.55%, each. Tatumella spp. on the other hand had a percentage occurrence of 9.09%. This study has buttressed the need for increased water hygiene of reservoir tanks as well as water sources in these locations.
