Cost Analysis of Calcium in Store Brand versus National Brand Grocery Products

Objective: This study was to determine if calcium fortification yields a higher price per serving in grocery store products. Researchers compared store brand to national brand grocery products in relation to cost in order to examine if calcium values were similar between store brand and national brand products. Methods: A total of 112 store brand and 211 national brand grocery products were collected from three low (national chain store), middle and high priced (Virginia and North Carolina regional store) grocery venues. Products were compared using price and calcium percentage per serving. ANOVA was used to determine between store brand and national brand for price per serving and calcium content, and between grocery venues. Results: National brand fortified products had a significantly lower mean price per serving when compared to national brand non-fortified products (p = 0.0002). There was no statistical difference between store brand fortified and non-fortified products (p = 0.9256). Low priced store brand products had the lowest mean price per serving ($0.34 ±0.24). Conclusions: This study found store brand products have similar calcium content as national brand products. Product cost was lower at low priced store compared to middle and high priced stores.     

From rationality to hyperreality: paradigm poker

This paper, following McGoun's (1997) seminal article comparing the economy of financial securities to a hyperreal poker game, argues that finance and accounting researchers should take the “linguistic turn” that has rejuvenated theory and research in many, if not most, of the social science and humanities in recent decades. In general terms, this means following Ludwig Wittgenstein's language game paradigm rather than Karl Popper's scientific deductive hypothesis testing methodology. The paper illustrates this by drawing on some of Jean Baudrillard's' ideas, particularly his concept of hyperreality and his phases of the image theoretic.The paper presents a poststructuralist genealogical analysis of the radical ruptures and reformulation of the meaning attributed to the accounting sign of earnings over the feudal, counterfeit, production, and simulation eras. It concludes that, as with many other signs in contemporary society, the earnings sign no longer has any relationship with, nor does it any longer refer to, any real or intrinsic profit but instead floats ungrounded in today's financial economy.The paper recommends that researchers in finance and accounting adopt paradigms from literary theory, semiotics, linguistics, and semiology rather than continue to rely on economics-based theory, which has lost its power for explaining and predicting happenings in today's financial economy of self-referencing models and images.     

Mapping the motivations and intentions of technology orientated entrepreneurs

The role of entrepreneurs in stimulating growth in the small business economy has received significant interest in the last three decades. This growing interest is prompted, in part, by the government’s assumption that the establishment and expansion of existing small firms could be greatly enhanced by the promotion of entrepreneurial education programmes in colleges and universities. Whilst there has been significant interest in the role, type and effect of entrepreneurs in the economy, few studies have examined the effect of entrepreneurial programmes on the progression of an idea through to commercialisation. This is because such research, whilst seemingly desirable, is problematic. Evidence can be gleaned through the development of suitable conceptual frameworks and methods, to assess the role and impact of entrepreneurial programmes on the commercialisation of products or processes, and the enhancement of entrepreneurial capabilities. To address this problem, the research will examine different approaches and frameworks that have been developed and applied hitherto. The objective of this will be to highlight the difficulties in assessing the motivations, cognitive and behavioural changes of entrepreneurs. Also, the research will demonstrate the need to undertake adequate controls, which illustrate possible improvement in entrepreneurial capabilities, networks, and credibility in comparison to students that embarked on courses without entrepreneurial elements. The process will confine itself to business development within the higher education (HEI) context. The MSEC has as its remit to provide opportunity, education, awareness and training to foster entrepreneurship within science and engineering departments across four universities in Greater Manchester. This setting will provide a unique situation in which to investigate the development of germinal technology businesses from the inception of an idea to the point of incubation, prototype development and investment. There is a requirement to understand the needs of the virgin entrepreneur, possible obstacles to commercialisation and the process of new venture creation. The methodology to be adopted has been identified, and forges new ground on combining positivist and phenomenological paradigms. The multi–paradigm approach supports the use of critical incident technique to reveal greater insights in to the personal and cognitive development of virginal entrepreneurs, the suitability of enterprise programmes to act as catalysts for venture creation, and their role in supporting technology transfer. The research will not only confine itself to examining undergraduate and postgraduate projects within MSEC’s business creation unit, but will also continue to assess the experience of entrepreneurs’ when they leave the programme. The research also documents the economic contribution of the programme, in terms of generation of new technology–based firms and the impact of entrepreneurs joining established small firms. Ultimately the aim is to build a long–term picture of the role of enterprise programmes in HEIs that will inform policy and practice.     

Theoretical considerations for a meaningful code of professional ethics

The professions have focused considerable attention on developing codes of conduct. Despite their efforts there is considerable controversy regarding the propriety of professional codes of ethics. Many provisions of professional codes seem to exacerbate disputes between the profession and the public rather than providing a framework that satisfies the public's desire for moral behavior.After examining three professional codes, we divide the provisions of professional codes into those provisions which urge professionals to avoid moral hazard, maintain professional courtesy and serve the public interest. We note that whereas provisions urging the avoidance of moral hazard are uncontroversial, the public is suspicious of provisions protecting professional courtesy. Public interest provisions are controversial when the public and the profession disagree as to what is in the public interest. Based on these observations, we conclude with recommendations regarding the content of professional codes.Karim Jamal is an Associate Professor in the Department of Accounting at the University of Alberta.

Fair markets

The paper challenges a minimalist strategy in business ethics that maintains if it's legal, it's moral. In hard cases, judges decide legal issues by appealing to moral ideals. Investigation shows that the bedrock concept is fairness. Often judges define fairness in terms of non-coerciveness or equality of bargaining power. The prudent manager must look beyond the legal department to the ethical notion of fairness. Moreover, if the courts were to consistently appeal to non-coerciveness and equality of bargaining power, some practices now considered morally acceptable would be neither moral nor legal. Norman E. Bowie is Professor of Philosophy and Director of the Center for the Study of Values at the University of Delaware.

Evaluation of dynamic stochastic general equilibrium models based on distributional comparison of simulated and historical data

We take as a starting point the existence of a joint distribution implied by different dynamic stochastic general equilibrium (DSGE) models, all of which are potentially misspecified. Our objective is to compare “true” joint distributions with ones generated by given DSGEs. This is accomplished via comparison of the empirical joint distributions (or confidence intervals) of historical and simulated time series. The tool draws on recent advances in the theory of the bootstrap, Kolmogorov type testing, and other work on the evaluation of DSGEs, aimed at comparing the second order properties of historical and simulated time series. We begin by fixing a given model as the “benchmark” model, against which all “alternative” models are to be compared. We then test whether at least one of the alternative models provides a more “accurate” approximation to the true cumulative distribution than does the benchmark model, where accuracy is measured in terms of distributional square error. Bootstrap critical values are discussed, and an illustrative example is given, in which it is shown that alternative versions of a standard DSGE model in which calibrated parameters are allowed to vary slightly perform equally well. On the other hand, there are stark differences between models when the shocks driving the models are assigned non-plausible variances and/or distributional assumptions.
