The Method of Teaching New Testament Greek

Based on teaching experience the author proposes an approach to teaching New Testament Greek which has resulted in greater use of the langauge and less fear of its study

A commentary on social & experiential (e-)retailing and (e-)shopping deserts

Purpose – The last ten years have seen a gradual withdrawal of retail facilities from many local areas and the consequent growth of ‘shopping deserts’, resulting in social and health disbenefits. This paper examines the potential for e-shopping to fill the vacuum and to assist disadvantaged shoppers. Design/methodology/approach – The paper uses prior published research to comment on the extent to which e-retailing may be the shopping solution of the future? Findings – The Internet has limited potential to compensate for shopping deserts, as consumers who do not have a good range of physical shops within walking distance also tend to lack access to the Internet. Research limitations/implications – The paper is based solely on prior research. The authors recommend action research that may hopefully help excluded shoppers to become more included by addressing the problems of access to e-shopping. Practical implications – Government, service providers and e-retailers are may consider interventions such as subsidised Internet access, training and the provision of e-cash. Originality/value – The paper links research from diverse fields relating to shopping deserts, the digital divide, health, wellbeing, social and experiential aspects of (e-)shopping

Myopia, customer returns and the theory of planned behaviour

As a prevalent and growing form of customer behaviour, deshopping is on the rise. Retailers' focus on good customer service and the offering of lenient returns polices has led to the growth in this fraudulent behaviour of customers in returning goods. This paper considers retailer myopia in the context of dishonest customer returns, applying the Theory of Planned Behaviour (TPB) using a quantitative questionnaire with 535 female consumers. The findings highlight the extent of the behaviour with 50% admitting to partaking in deshopping. The TPB variables can be utilised to manage and prevent deshopping. The results indicate that currently these customers perceive it to be easy to deshop as there are no consequences with the result that such behaviour continues to grow. If retailers were less myopic they would monitor returns more thoroughly and make it less easy for such customers to get away with undesirable deshopping behaviour. The paper makes recommendations for retailers to manage or alter perceived behavioural characteristics for customers, which in turn, would reduce tendencies for dishonesty in customers returning goods for refunds. Retail myopia is evident with deshopping behaviour with consequences for retailers in time, effort and costs

Integer polyhedra for program analysis

Polyhedra are widely used in model checking and abstract interpretation. Polyhedral analysis is effective when the relationships between variables are linear, but suffers from imprecision when it is necessary to take into account the integrality of the represented space. Imprecision also arises when non-linear constraints occur. Moreover, in terms of tractability, even a space defined by linear constraints can become unmanageable owing to the excessive number of inequalities. Thus it is useful to identify those inequalities whose omission has least impact on the represented space. This paper shows how these issues can be addressed in a novel way by growing the integer hull of the space and approximating the number of integral points within a bounded polyhedron

Concentration Levels in the U.S. Advertising and Marketing Services Industry: Myth vs. Reality

This paper analyzes changes in concentration levels in the U.S. Advertising and Marketing Services (A&MS) industry using publicly released data that have been largely ignored in past discussions of the industrial organization of this industry, namely those available from the U.S. Census Bureau's quinquennial Economic Census and the Service Annual Survey. We define the A&MS industry in terms of nine sectors, each of which is represented by a separate 5 digit NAICS category. In so doing, we have sought to redress some of the measurement problems surrounding estimates found in the existing literature. Our main findings are threefold. First, in the case of the core and largest sector, Advertising Agencies, firm level concentration as measured by Herfindahl-Hirschman Index (HHI) increased slightly but remained relatively low from 1977 to 2002. All of the HHI estimates readily satisfied the standard widely used to characterize an industry as "unconcentrated." We find mixed support for the hypotheses that the ranks of mid-sized agencies were depleted by ongoing waves of mergers and acquisitions and resulted in a polarized size structure. The size distributions of agency revenue have become more polarized in the sense that over time they appear more skewed, more dispersed, and exhibit greater inequality. The share of total receipts realized by small agencies fell while that of large agencies rose. However, the position of mid-sized agencies appears to have changed little over the period 1977- 2002, as measured by the shares of agencies and receipts they represent. Second, concentration levels in 1997 and 2002 varied across the nine sectors comprising the A&MS industry, but all were within the range generally considered as indicative of a competitive industry. Third, we developed concentration ratios at the level of holding companies (HC's) and find that the four largest HC's captured between a fifth and a quarter of total revenue from the A&MS industry, a share that remained quite stable over the period, 2002-2006. These estimates are lower by an order of magnitude than estimates often cited in the trade press. Reasons for the discrepancy are discussed.

The Behavior of Money, Credit, and Prices in a Real Business Cycle

This paper analyzes the interaction of money and the price level with a business cycle that is fully real in origin, adopting a view which differs sharply from traditional theories that assign a significant causal influence to monetary movements. The theoretical analysis focuses on a banking system that produces transaction. services on demand and thus reflects market activity. Under one regime of bank regulation and fiat money supply by the monetary authority, the real business cycle theory predicts that (i)movements in external monetary measures should be uncorrelated with real activity and(ii) movements in internal monetary measures should be positively correlated with real activity. Preliminary empirical analysis provides general support for this focus on the banking sector since much of the correlation between monetary measures and real activity is apparently with inside money.
