Ethnic differences in the academic achievement process in Canada

This research examines the extent to which differences in achievement between German-speaking and French-speaking students are accounted for by theoretically related intervening variables and the extent to which the entire achievement process differs across the two ethnic groups. For the two ethnic groups, both main effects and interaction effects have significant consequences for the academic achievement process, even when a number of other variables are controlled. The results suggest that the whole process works to the benefit of the German-speaking students and to the detriment of the French-speaking students.     

Food security, consumption diversification and foreign exchange balances in Indonesia: Results from a multi-commodity simulation

Many countries adopt economic development strategies, within which an important element is the maintenance of low and stable food prices. In Indonesia, this is achieved principally through government subsidies to consumers of imported rice, the total cost of which fluctuates considerably from year to year, depending on world price movements and domestic production performance. Higher and possibly less stable domestic food prices appear inevitable in Indonesia, however, as the spectre of reduced oil revenues increases the government's concern with the cost of its food policy. Results from a stochastic simulation model of the agricultural sector show that the food price risk to which consumers and producers would be exposed in the absence of the stabilizing component of Indonesia's food policy would be considerable, rendering this component an unlikely area for significant change. A viable policy option appears to be the continuance of rice and wheat price stabilization, but with a graduated increase in the relative price of rice, reaching a total of 10% by 1985. Such a policy could result in net self-sufficiency in foreign exchange from staple food trade by 1990 and an improvement in aggregate economic surplus, although the expected decade improvement in food-energy consumption per capita would fall from 10% to 8%.     

A Family Therapy Approach to Alcoholism*

Data accumulated from recent studies strongly suggest that family therapy is a promising method of treatment for alcoholism. In this paper a comprehensive treatment approach is proposed, based on known characteristics of alcoholic family systems and the author's clinical experiences in working with families of alcoholics. Specific strategies are described that can enhance treatment success by reducing resistances and maximizing changes in dysfunctional family interaction patterns. The relationship between the spouses is such as to perpetuate the need for alcohol. The major focus in therapy therefore is on understanding and changing the marital relationship.     

When Precaution Creates Misunderstandings: The Unintended Effects of Precautionary Information on Perceived Risks,the EMF Case

In the past decade, growing public concern about novel technologies with uncertain potential long‐term impacts on the environment and human health has moved risk policies toward a more precautionary approach. Focusing on mobile telephony, the effects of precautionary information on risk perception were analyzed. A pooled multinational experimental study based on a 5 × 2 × 2 factorial design was conducted in nine countries. The first factor refers to whether or not information on different types of precautionary measures was present, the second factor to the framing of the precautionary information, and the third factor to the order in which cell phones and base stations were rated by the study participants. The data analysis on the country level indicates different effects. The main hypothesis that informing about precautionary measures results in increased risk perceptions found only partial support in the data. The effects are weaker, both in terms of the effect size and the frequency of significant effects, across the various precautionary information formats used in the experiment. Nevertheless, our findings do not support the assumption that informing people about implemented precautionary measures will decrease public concerns.     

A grounded theory research approach to building and testing TQM theory in operations management

Total quality management (TQM) has continued to develop as a strategic business improvement approach in organisations and within the Operations Management literature. Strategic TQM is a dynamic phenomenon, reflecting the complexity and technology development in the business environment. Therefore, this conception of TQM has led to significant challenges with regards to developing suitable models and research methodology where traditional, and normative research data, includes survey responses associated with deductive theory and testing. Such data, and its use, is often premised on cause and effect rationality and fails to supply deep rich data to address meanings, phenomena and complex socio-political events, which is a feature of strategic TQM.     

Public accountability in non-profit industrial development organisations

Non-profit industrial development organisations (NIDOs) represent a common but little studied community response to widespread deindustrialisation in the United States. These non-profits are organised as chartered not-for-profit corporations, public authorities or agencies of local government. Most receive at least some public funding to promote local industrial development. Thus, a key issue is how accountable NIDOs are to the public they have been created to serve. Data from national surveys of NIDO executive directors in 1984 and 1994, as well as a survey of six case study boards of directors, suggest that public accountability is an increasingly important concern among NIDOs. Public hearings, efforts to diversify the boards in terms of gender and race, and connections to community development corporations and other local organisations are among the ways NIDOs attempt to be accountable to the general public. Although few women or racial minorities serve on NIDO boards, those boards with representation of these groups tend to be more concerned with public accountability. Boards containing public officials tend to be less concerned, presumably because their presence makes the NIDOs more directly accountable as a result of the participation of elected public representatives.     

A concept of an integrated transport model

This paper is one of a series being produced on the application of Operational Research techniques in the integrated planning of public service resource provision and consumption. It describes a conceptual basis for planning transportation services within the context of a public service, the others are related to Health Services, Educational Services and community development services.Two sub-models, a linear sub-model and a dynamic sub-model are linked to form the integrated approach to the planning problem. The overall concept is to evaluate in terms of penalties and benefits the alternative plans of resource provisions.It is of interest to know that the principles of the Linear model described here has been applied to long range planning in the Health Service in the U.S.A. and U.K., and has been reported at the NATO conference, Portugal (1974). The Dynamic model has been used, in a more unstructured fashion than described here, by the Greater London Councils. The model in this paper is to form the basis of a more detailed evaluation of alternative transportation plans.     

Micro Foundations of Religion: A Revised Theory

In a major revision of my earlier theoretical work on religion, I attempt to identify and connect the basic micro elements and processes underlying religious expression. I show that all primary aspects of religion—belief, emotion, ritual, prayer, sacrifice, mysticism, and miracle—can be understood on the basis of exchange relations between humans and supernatural beings. Although I utilize a cognitive definition of religion, this new version of the theory is especially concerned with the emotional and expressive aspects of religion. Along the way I also clarify the difference between religion and magic and this sets the stage for explaining the conditions under which religion (but not magic) can require extended and exclusive exchange relations between humans and the gods, thus enabling some religions to sustain stable organizations based on a lay membership.
