The primary and secondary market activity in collectible sportscards has evolved into that of a primitive, but organised financial market. This report reviews some aspects of the collectible sportscard market. The objective of the report is to introduce the sportscard investment medium to finance professionals, including those interested in the research potential of the market. The report includes an empirical analysis of the performance of some selected sportscard portfolio strategies for the period between March 1988 and December 1993. Sportscard collecting has evolved from an adolescent hobby of the 1950s into an active national market, estimated to involve approximately $5 billion and 3 million persons and served by a network of dealers and price information suppliers. The evolution of the sportscard market into its current state is described in this presentation. The description includes an empirical analysis of the performance of some selected sportscard portfolio strategies for the period between March 1988 and December 1993. The objective of the report is to provide information to those considering collectible sportscards as an investment medium and to those who might be interested in conducting financial research with collectible sportscard pricing data.

While an operation's unlevered value is objective, the value of the debt tax shield is subjective since it depends on the capital structure policy of the firm that owns the operation. The purpose of this paper is to explore the implications of this subjective nature of debt tax shield value for corporate investment decisions.

The study develops a simple theoretical model.

The paper shows that even a low probability of selling a project in the future to a firm with a different tax shield value can significantly affect a project's weighted average cost of capital (WACC) and total value.

Managers should be aware of this issue when making corporate investment decisions.

This is the first study to address the implication of the subjective nature of debt tax shield value.

It is estimated that more than half of the construction industry’s projects encounter significant cost overruns and major delays, resulting in the industry having a tarnished reputation. Therefore, it is crucial to identify key project cost and schedule performance factors. However, despite the attempts of numerous researchers, their results have been inconsistent. Most of the literature has focused solely on the construction phase budget and time overruns; the engineering/design and procurement phase costs and schedule performances have been rarely studied. The paper aims to discuss these issues.

The objective of this study was primarily to identify and prioritize engineering, procurement and construction key performance factors (KPFs) and to strategize ways to prevent performance delays and cost overruns. To achieve these objectives, more than 200 peer-reviewed journal papers, conference proceedings and other scholarly publications were studied and categorized based on industry type, physical location, data collection and analysis methods.

It was concluded that both the time required to complete engineering/construction phases and the cost of completing them can be significantly affected by design changes. The two main causes of delays and cost overruns in the procurement phase are construction material shortages and price fluctuations. Other factors affecting all phases of the project are poor economic condition, equipment and labor shortages, delays in owners’ timely decision making, poor communication between stakeholders, poor site management and supervision, clients’ financial issues and severe weather conditions. A list of phase-based strategies which address the issue of time/cost overruns is presented herein.

The findings of this study address the potential confusion of the industry’s practitioners related to the inconsistent list of potential KPFs and their preventive measurements, and pave the way for the construction research community to conduct future performance-related studies.

Productivity is a worldwide problem and efforts have been made over the last three decades or so to explore ways to increase the rate of productivity on construction sites. The purpose of this paper is to investigate the state of the art in productivity research and to present the findings of a survey into the factors that can impair productivity on site.

A literature review is structured under five general headings: pre-construction activities; activities during construction; managerial and leadership issues; motivational factors; and organizational factors. In total, 46 determinants were extracted from the above headings and were assessed by 36 main contractors.

The literature review revealed that while there has been an advancement in developing techniques and tools to improving productivity on site, more need to be done to invest in technology and innovation. The interview survey indicated that factors associated with pre-construction activities, namely, the “experience of the selected site and project managers,” “design errors,” “buildability of the design,” “project planning,” “communication,” “ leadership style” and “procurement method” as the most critical factors influencing site productivity. Other highly ranked factors are “mismanagement of material” and “the work environment.”

The survey is based on main contractors and thus not generalized to cover other sectors of the building team such as designers and engineers.

Outcome of this research can be used to provide professionals and contractors guidance for focussing, acting upon and controlling the most significant factors perceived to influence the construction labor productivity (CLP) on site.

First, reviewed the state of the art and trends in construction productivity research. Second, primary survey with industry experts to rank the relative importance of factors that can influence CLP on site.

The use of information and communication technology (ICT) for business processes has witnessed exponential growth over the past two decades. This paper aims to explore the level of use of ICT infrastructure in the Nigerian construction industry and analyse the implications for construction management practice.

Using quantitative questionnaire survey, data from 148 respondents were analysed with the help of descriptive and inferential statistics as well as multiple regression analysis.

Findings establish project managers, site managers and quantity surveyors as the primary users of ICT with regards to the variety of ICT devices in the Nigerian construction industry, while the foremen are the least users. Besides, word processing/accounting systems, electronic communication systems and project management systems are the three top rated in terms of frequency of use, while quality as well as cost impacts of ICT infrastructure use are established as the most important factors contributing to overall project performance.

The study establishes causal relationships between ICT infrastructure use and project performance within the context of Nigeria’s construction industry.

A collection of essays by a social economist seeking to balance economics as a science of means with the values deemed necessary to man′s finding the good life and society enduring as a civilized instrumentality. Looks for authority to great men of the past and to today′s moral philosopher: man is an ethical animal. The 13 essays are: 1. Evolutionary Economics: The End of It All? which challenges the view that Darwinism destroyed belief in a universe of purpose and design; 2. Schmoller′s Political Economy: Its Psychic, Moral and Legal Foundations, which centres on the belief that time‐honoured ethical values prevail in an economy formed by ties of common sentiment, ideas, customs and laws; 3. Adam Smith by Gustav von Schmoller – Schmoller rejects Smith′s natural law and sees him as simply spreading the message of Calvinism; 4. Pierre‐Joseph Proudhon, Socialist – Karl Marx, Communist: A Comparison; 5. Marxism and the Instauration of Man, which raises the question for Marx: is the flowering of the new man in Communist society the ultimate end to the dialectical movement of history?; 6. Ethical Progress and Economic Growth in Western Civilization; 7. Ethical Principles in American Society: An Appraisal; 8. The Ugent Need for a Consensus on Moral Values, which focuses on the real dangers inherent in there being no consensus on moral values; 9. Human Resources and the Good Society – man is not to be treated as an economic resource; man′s moral and material wellbeing is the goal; 10. The Social Economist on the Modern Dilemma: Ethical Dwarfs and Nuclear Giants, which argues that it is imperative to distinguish good from evil and to act accordingly: existentialism, situation ethics and evolutionary ethics savour of nihilism; 11. Ethical Principles: The Economist′s Quandary, which is the difficulty of balancing the claims of disinterested science and of the urge to better the human condition; 12. The Role of Government in the Advancement of Cultural Values, which discusses censorship and the funding of art against the background of the US Helms Amendment; 13. Man at the Crossroads draws earlier themes together; the author makes the case for rejecting determinism and the “operant conditioning” of the Skinner school in favour of the moral progress of autonomous man through adherence to traditional ethical values.

A PILGRIMAGE to West Cornwall can be heartily recommended to any librarian in search of rest, fresh air, and complete change from the monotony of town life. Here he will find abundance of interest and novelty in connection with the habits and customs of the ancient Britons still extant, and derive many impressions of pleasure from the magnificent rock scenery with which the coast abounds. Dairy‐farming, tin‐mining, pilchard fishing, druidical monuments, and wild flowers can also be studied with profit; and even Public Libraries, in a condition of arrested development not uncommon in other districts of England. Cornwall is pre‐eminently the county for Public Libraries. Geographically it is remote from the populous parts of England, and the Great‐Western Railway Company, with commendable forethought, have taken enormous pains to maintain this seclusion by a most pitiful and inadequate service of trains. I was once assured by the Public Librarian of Penzance that no thief would ever raid his institution, for the simple reason that it was impossible to get away quick enough to avoid detection ! A place thus difficult to get away from, is manifestly one which requires strong home interests to make it attractive, and, as theatres, music halls, and other light diversions, find little favour in Cornish towns, the Public Library, with its wealth of varied reading, is practically the only after‐dark resource left. But there are other circumstances which make Cornwall an ideal county for a liberal provision of Public Libraries. The decline of the mining industry has driven many of the men away to other centres, such as South Africa, and it is well‐known that, at the present time, more money is coming into the county from exiled sons abroad than is being made locally. There is thus an enormous surplus of that great natural reader— woman—and to her should be offered in profusion plenty of romantic and other reading as a solace and compensation for the loss of her natural companion—man.

The future construction site will be pervasive, context aware and embedded with intelligence. The purpose of this paper is to explore and define the concept of the digital skin of the future smart construction site.

The paper provides a systematic and hierarchical classification of 114 articles from both industry and academia on the digital skin concept and evaluates them. The hierarchical classification is based on application areas relevant to construction, such as augmented reality, building information model-based visualisation, labour tracking, supply chain tracking, safety management, mobile equipment tracking and schedule and progress monitoring. Evaluations of the research papers were conducted based on three pillars: validation of technological feasibility, onsite application and user acceptance testing.

Technologies learned about in the literature review enabled the envisaging of the pervasive construction site of the future. The paper presents scenarios for the future context-aware construction site, including the construction worker, construction procurement management and future real-time safety management systems.

Based on the gaps identified by the review in the body of knowledge and on a broader analysis of technology diffusion, the paper highlights the research challenges to be overcome in the advent of digital skin. The paper recommends that researchers follow a coherent process for smart technology design, development and implementation in order to achieve this vision for the construction industry.

The aim of this study was to address the unmet information needs of Malawian informal carers. We report on a three-year project which we co-created with informal carers, medical doctors and NGOs with the view to disseminate health advisory messages.

This study was developed on the principles of co-production. The impact of our health advisory messaging approach was assessed through observations and questionnaire-based surveys for quality, clarity and usefulness.

The messages were disseminated beyond the local support groups and reached a much wider community via word of mouth. The messages also led to short and medium term benefits for informal carers and their loved ones.

Our findings highlight the importance of understanding the contextual conditions of informal caring and that of co-producing interventions with the people these aim to benefit.

Services for offenders who have learning disabilities are generally provided in secure and medium secure units. These services are often provided in segregated and congregated settings using therapeutic interventions. This paper presents a case study of a housing‐based service provided within the community, based on developing valued social roles for vulnerable people.In 2003 the then Labour government in the UK sought to align all of the state benefits paid to people who were not in work due to disability and other disadvantages. The resulting ‘transitional housing benefit’ integrated housing benefit and other support grants, with the aim of providing vulnerable people and service providers with a single point of reference when it came to the funding of accommodation and support. The service is based on the principle of normalisation (Wolfensberger, 1972; Tyne & O'Brien, 1981), the theory of social role valorisation (SRV) (Wolfensberger & Thomas, 1983; Wolfensberger et al, 1996; Race, 1999) and O'Brien's Framework for Accomplishment (O'Brien, 1987) and provides a credible alternative to more traditional approaches.The paper provides a critical introduction to SRV and O'Brien's Framework and how their principles have been used to support people with complex needs. It discusses some of the structures and attitudes prevalent in society or, as Wolfensberger calls them, the ‘domains’ and ‘major channels’ by which people with learning disabilities are oppressed.The case study includes examples of practice and shows some interesting differences in patterns of referral and destination routes for males and females and concludes with some implications for practice.
