This study empirically examined the views of Certified Internal Auditors (CIAs) concerning the role of Code of Ethics for members of the Institute of Internal Auditors. It is a continuation of an earlier study which examined the usefulness of the Code to CIAs. Among the questions asked were what is the primary reason for the Code of Ethics, how useful is it, have you used it, should more enforcement actions be taken against members who violate the Code, and what are the legal and moral responsibilities of the CIA to report serious ethical violations, e.g., environmental pollution, to outsiders when top management and the board of directors are aware of the matter but are not doing anything to correct it. The results indicate strong support for the Code, its enforcement, and use as an instrument to encourage the internal flow of ethical behavior by embers and others.Philip H.

This study examines whether differences in financial performance exist for investment trusts which base their portfolio selection primarily on an ethical screen, compared to indexes which incorporate a broader spectrum of investments. Results indicate that on a risk-adjusted basis there is an insignificant difference in the financial performance of these trusts against three common market benchmarks. However as to the extent of the directional effect, there does exist slightly superior financial performance by ethical trusts against their respective industry average indexes, but an underperformance against a smaller company's index and the market as a whole. The lack of a distinct advantage in the short to medium term for applying an ethical screen, may in part be due to the recent development of ethical investments in Australia. Stronger performances by older ethical investment trusts may indicate superior returns are more likely to occur over a longer term.  相似文献

Beef ranchers in British Columbia rely upon Crown range for a large proportion of their summer and fall grazing needs. Any improvement in the management policies for this resource can enhance the economic viability of the beef sector. The objective of this study is to evaluate the stocking levels of stock ranges administered by range agrologists and to compare their assessment with that derived using a more formal planning procedure. The report details the stocking capacity for the Punchaw Stock Range in the Prince George range district. Capacities for other stock ranges are also estimated. When rotational uses are defined and examined, the optimal use pattern results in carrying capacities that are approximately double that of current or recommended stocking levels. Les producteurs de bovins de Colombie-Britannique dépendent des parcours de la Couronne pourune grande partie de leurs besoins en pâturages ?été et ?automne. Toute amélioration des politiques de gestion de cette ressource risque ?avoir un effet salutaire sur la viabilité économique du secteur des bovins. La présente étude avait pour objectif ?évaluer ?intensity de pâturage sur les parcours gérés par des agronomes et de comparer leur évaluation à celle obtenue au moyen ?une méthode de planification répondant à des critères plus officiels. Nous fournissons des données détaillées sur la capacité de charge correspondant du parcours Punchaw, dans le district Prince George. Nous procédons en outre à ?évaluation de la capacité de charge ?autres parcours. Lorsque ?exploitation en rotation est définie et examinée, le calcul de ?utilisation optimale donne une capacité de charge correspondant approximativement au double des valeurs actuelles ou recommandées.  相似文献

We consider the implications of the three pillars of sustainability (environment, economy and social justice) on consumption in a wealthy country. Building a theoretical model that includes consumers, business, government, the environment, and economic and political relations between nations, we explore how sustainability should affect the consumption behavior of consumers, charitable aid to poorer countries, and responsible environmental practices by businesses. Our model enables us to provide normative implications for consumers, society and business. Importantly, we assume that all stakeholders will optimize their self-interest, and that altruism will only partly explain behavior consistent with sustainability. Among the more non-obvious findings are that (1) the poorer the poor countries are, the less the rich countries should consume, (2) the more sensitive the global political climate is to economic inequity between the rich and poor nations, the less the rich countries should consume, and (3) if aid to poor countries is effective enough, then the more materialistic the society is, the more charitable aid it should give. We also confirm a number of more intuitive findings, such as that business should use more green technology as the taxes on pollution and/or efficiency of green technology increase, and the more resource-intensive consumption is, the less consumers should consume. Taken as a whole, the findings imply that societal consumption patterns should be sensitive to aspects of environmental impact and social justice, even if altruistic motivations are absent.  相似文献
