Abstract

Purpose

This paper aims to develop and test a conceptual model of supplier selection decisions in the public sector. The study seeks to determine the relative importance of a broad range of non-economic variables in explaining supplier selection decisions during strategic organizational purchases.

Design/methodology/approach

Data were collected from a national sample of 341 senior staff and top management team (TMT) members in 40 public sector organizations in Nigeria by using structured questionnaires.

Findings

Results of structural equation modeling (SEM) analysis shows that government policy requirements, social ties of organizational actors, party politics, decision-makers’ experience and the perception of instrumental ethical work climates are the most important determinants of strategic supplier selection decisions, followed in a descending order of importance by the perception of rules ethical work climates, self-enhancement personal values, CEOs’ structural position, self-transcendent personal values and the perception of time pressure. Findings also indicate that the choice of a supplier per se is not an important determinant of organizational performance.

Originality/value

No prior study has brought together, in a single model, the broad range of variables employed in this study with a view to exploring their relative importance in explaining public sector supplier selection decisions in a non-western country context. The findings of this study have implications for Marketing Managers looking to do business with public sector firms in emerging markets.

Abstract

Purpose

Using public universities as research setting, this study explored whether perception of the prevalence of instrumental ethical climate (IEC) differ among employees based on their gender, age, education levels, job tenure and status.

Design/methodology/approach

Structured survey questionnaires were used in collecting data, and responses from a final sample of 101 senior level university employees were used in the analysis.

Findings

Results of independent t-tests and one-way analysis of variance (ANOVA) showed that although participants had a high overall perception of the presence of IEC in their organisations, statistically significant differences in perception were only found for the gender and education level groups. Furthermore, this research concludes that females are more perceptive of, and sensitive to, the existence of unethical decision-making conditions in their work place, compared to males employees; and that employees with low levels of education are more likely to perceive stronger levels of IECs in their work environment, compared to their more educated counterparts.

Research limitations/implications

Although the sample size is large enough for the kind of inferential analytical method employed in this study, it may not be representative of all the public universities in Nigeria. Furthermore, given that private organisations may encourage different ethical work climates than public establishments, the generalisability of our findings is limited.

Practical implications

To reduce unethical practices in public universities, more women should be encouraged to take up top decision-making positions.

Originality/value

Compared to the general business and public service fields, the current study is one of very few studies that empirically examined individual-level antecedents of ethical climate in African Universities.

Abstract

Purpose

The purpose of this paper is to examine the relationship between ethical work climates (EWCs) and supplier selection decisions (SSDs), and the moderating roles of party politics and personal values on this relationship.

Design/methodology/approach

A total of 600 senior-level personnel from 40 Nigerian public organizations were surveyed using structured questionnaires. Multiple regression analysis was used to test the hypotheses developed for the study after assessing construct reliability and validity.

Findings

Results show that both high and low levels of external political pressures significantly reduce the perception that organizational SSDs are ruled based and pro-social in nature. Furthermore, regardless of the level of perception of instrumental personal values by employees, instrumental ethical climates significantly determine SSDs; principled/cosmopolitan climate and benevolent/cosmopolitan climate only become significant perceptible determinants when there is less room for the accommodation of personal goals during SSD processes.

Research limitations/implications

This study only examined the relationship between ethical climate perceptions and SSDs without controlling for the effects of some important possible intervening variables on this relationship. Therefore, the study encouraged future researcher to enhance the generalizability of the findings by incorporate relevant control variables in the model, as well as examining other decision phases in the public buying process.

Originality/value

This study is original to the extent that only a few studies in the literature are devoted to perceptions of EWCs in African organizations, and no previous studies have examined this phenomenon in relation to SSDs in Nigerian public firms.

The aim of this paper is to better understand the impact of petroleum production facilities on ambient air quality of host airshed.

Abstract

Purpose

The aim of this paper is to better understand the impact of petroleum production facilities on ambient air quality of host airshed.

Design/methodology/approach

Field measurements were taken daily for four consecutive months around petroleum production facilities in the Niger Delta area, of Nigeria, one of the world's important petroleum producing areas. Statistical analysis tool and air quality analytical tool known as the air quality index (AQI) were applied on the field data obtained.

Findings

The mean measured daily concentrations of both carbon monoxide (CO) and nitrogen dioxide (NO2) between distances 50 and 500 m of petroleum flow stations were of the range 140 – 3400 μg/m3 and 23 – 1250 μg/m3 respectively. The AQI from measured CO concentrations in the study area ranged between 1 and 44, an indication of good AQI category with no known health effects but a need for cautionary statement. Similarly, over 97 percent of the measured concentrations of NO2 were below 0.60 ppm which implies that the AQI of the host environment of the flow stations were below 200 with respect to NO2 thus indicating a good category of air with no health alarm. However, at the 60 m distance around a flow station, the AQI was 210 thus the quality of available air at this point could be described as very unhealthy. Generally the concentrations of CO were higher than NO2 in all the distances from the flow stations and were corroborated with their significant T‐test values. The T‐test results of the relationship between the concentrations of the air pollutants per time of the day, showed that their T‐test values were not significant, indicating that concentrations of these air pollutants were independent of the sampling time. A strong and positive correlation existed between the two air pollutants signifying common sources.

Originality/value

The paper highlights that at 60 m distance around petroleum production facilities, people with respiratory or heart disease, the elderly and children should be prevented from gaining access in the morning without taking necessary precautionary measures against the inhalation of air pollutants.
