The trickle-down effect of psycho-social constructs and knowledge deficiencies as organizational barriers to cost performance on highway projects

Purpose The study proffers a theoretical narrative explaining the poor financial performance of public highway agencies in Nigeria. This study critically spotlights seminal works in the literature offering theoretical narratives on the poor financial performance of public infrastructure projects, to discuss whether they adequately capture the relationship between psychological factors, project governance/leadership issues, and knowledge/skill deficiencies related to the cost performance of infrastructure projects in the developing world. The evaluation reveals the predominant contextual exclusivity of these theoretical narratives to the developed world, which tend to under-represent developing countries, such as those on the African continent. Design/methodology/approach Using a case study research strategy, longitudinal documentary/archival data for 61 highway projects were analyzed. Sixteen interviews were also conducted with highway officials from the three highway agencies responsible for the execution of the projects. A two-stage deductive-inductive thematic analysis of the collated data was carried out to identify barriers to the financial management of public highway projects, the result of which is cognitively mapped out. Findings The study showcases empirical insight on cost overruns experienced in Nigerian public projects, due to the trickle-down effect of human and organizational environment, as well as due to workers’ knowledge/skill deficiencies. Research limitations/implications The developed theory is contextual to Nigeria, as such there is scope for testing its generalisability to other developing nations. Originality/value The in-depth trajectory provided, uncovers an intricate web of technical and psycho-social, organizational and institutional issues, which have not been identified and explained by previous theoretical narratives

Mobility of Old People and Housewives : a Study in Guildford, 1975

Abstract copyright UK Data Service and data collection copyright owner.The aim of this survey was to study the travel patterns of old people and the role of transport in their every day lives. A sample of housewives was also surveyed in order to compare some aspects of the travel behaviour and difficulties of old people with a younger group of people with limited mobilty living in the same town.Main Topics:Attitudinal/Behavioural Questions Questions covered difficulties with and use of transport modes,giving up cars and driving, and the effect of ill health on walking ability; a travel diary covered all journeys (including short walks) made in the previous day; detailed sections on travel to the town centre, shops, post office, doctor, hospital, friends and relations. Questions on the location of places visited, frequency of travel, modes used and journey time. Substitutes for travel for different purposes were also included. Straight-line distances were calculated for each respondent between home and various destinations visited; these distances were added to the data file. Background Variables Background variables included age, sex, marital status, working status, household composition, driving licence- holding and household car ownership, distance from town centre, tenure, length of residence, previous residence, social class and SEG, and income additional to state pension and supplementary pension
