The Value of Environmental Information without Control of Subsequent Decisions

The standard value of information approach of decision analysis assumes that the individual or agency that collects the information is also in control of the subsequent decisions based on the information. We refer to this situation as the “value of information with control (VOI‐C).” This paradigm leads to powerful results, for example, that the value of information cannot be negative and that it is zero, when the information cannot change subsequent decisions. In many real world situations, however, the agency collecting the information is different from the one that makes the decision on the basis of that information. For example, an environmental research group may contemplate to fund a study that can affect an environmental policy decision that is made by a regulatory organization. In this two‐agency formulation, the information‐acquiring agency has to decide, whether an investment in research is worthwhile, while not being in control of the subsequent decision. We refer to this situation as “value of information without control (VOI‐NC).” In this article, we present a framework for the VOI‐NC and illustrate it with an example of a specific problem of determining the value of a research program on the health effects of power‐frequency electromagnetic fields. We first compare the VOI‐C approach with the VOI‐NC approach. We show that the VOI‐NC can be negative, but that with high‐quality research (low probabilities of errors of type I and II) it is positive. We also demonstrate, both in the example and in more general mathematical terms, that the VOI‐NC for environmental studies breaks down into a sum of the VOI‐NC due to the possible reduction of environmental impacts and the VOI‐NC due to the reduction of policy costs, with each component being positive for low environmental impacts and high‐quality research. Interesting results include that the environmental and cost components of the VOI‐NC move in opposite directions as a function of the probability of environmental impacts and that VOI‐NC can be positive, even though the probability of environmental impacts is zero or one.     

A Method of Assembling Cross-sectional Indicators into a Community Quality of Life

This study develops a new method of measuring quality of life at the local and state level. Further, it presents a methodology that combines heterogeneous indicators from different fields, such as economics, social, and health, into one total measurement. The technique shown can be used to compare one region with another, or compare one metro area with its own performance through time. The analysis shows which categories and indicators are ranked as the highest and serves as a measurement of economic development and potential targets for marketing plans. Every analyst interested in an aggregate, community measurement tool should be interested in the procedure and results.     

Human Behavior,Social Environment,Social Reconstruction,and Social Policy: A System of Linkages,Goals, and Priorities

The idea of a wholesome relationship between human behavior and the forces of social environment is the focal point of this article. The author seeks to reconceptualize the goals and foci of the HBSE¹ component in the light of knowledge that underscores the need for social reconstruction. A conceptual model is offered to show appropriate linkages between different focal units. It is recommended that the HBSE and social policy components be taught in harmony with the mission of social work and in the context of humankind's prevailing condition rather than at mere systems levels.     

Urban multiculture and everyday encounters in semi‐public,franchised cafe spaces

This paper engages with an emergent literature on multiculture and concepts such as conviviality and negotiation to explore how increasingly ethnically diverse population routinely share and mix in urban places and social spaces. As part of a wider ESRC funded, two‐year qualitative study of changing social life and everyday multiculture in different geographical areas of contemporary England, this paper draws on participant observation data from three branches of franchised leisure and consumption cafe spaces. We pay particular attention to the ways these spaces work as settings of encounter and shared presence between groups often envisaged as separated by ethnic difference. Our findings suggest that corporate spaces which are more often dismissed as commercial, globalized spaces of soulless homogeneity can be locally inflected spaces whose cultural blandness may generate confident familiarity, ethnic mixity, mundane co‐presence and inattentive forms of conviviality.     

Statistical Analysis of Uncertainties in Deterministic Computational Modeling – Application to Composite Process Resin Infusion Flow Model

Deterministic physics-based flow modeling provides an effective way to simulate and understand the resin flow infusion process in liquid composite molding processes and its variants. These are effective to provide optimal injection time and locations prior to gelation for given process parameters of resin viscosity and preform permeability. However, there could be significant variations in these two parameters during actual manufacturing. This paper presents simulation-based statistical analysis of uncertainties of these process parameters involved in the resin flow infusion. Two key process parameters, viscosity and permeability, and their statistical variations are examined individually and subsequently in combination for their impact on the associated injection time. Values from statistical probability distribution of the process parameters were employed to find the solution space for this engineering application through deterministic physics-based process flow modeling simulations. A bivariate confidence envelope was developed using the appropriate Cumulative Density Function for a 95% probability of successfully completing resin infusion prior to physical resin gelation time. A logistic regression model for the influence of resin viscosity and permeability on the binary response of successful resin infusion is presented and conforms well to the sensitivity analysis inferences.

Fisher''s inequality for designs on regular graphs

Let G=(V,E) be a regular graph of valency d. A (v,k,λ,μ)-design over G is a pair , where is a family of k-subsets of V (blocks) such that for any distinct vertices x and y, the number of blocks containing {x,y} is equal to λ if {x,y} is an edge and is equal to μ if {x,y} is not an edge. We will prove that the number of vertices does not exceed the number of blocks (Fisher's Inequality) under the following condition: (r−μ)/(μ−λ) is not a multiple eigenvalue of the adjacency matrix of the graph (r is the replication number of the design). We also give examples showing that this restriction is essential.

Ethics and human resource management and development in a global context: case study of an Indian multinational

A firm's orientation to ethics is influenced largely by its national and organizational culture. Research shows that a growing number of Indian firms place a distinct emphasis on long-term orientation to business strategy with a social mission, underpinned by firm commitment to core organizational values, employee development and welfare. Through a case study of a large Indian multinational conglomerate, this article provides preliminary evidence of how some emerging economy firms are successfully mixing and matching indigenous business and people management strategies with the Western emphasis on meritocracy and professionalism to compete in the contemporary global economy. It further shows how the human resource development (HRD) discipline can play a pro-active role in embedding ethics and values throughout the organizational and HR architecture. The HRD professionals in the case study firm also face several structural and cultural challenges in discharging their ethics-driven HR mandate, such as management's ethnocentric attitude to global staffing and clash of work cultures.     

Letter to the Editor

The social work profession has a long standing commitment to human rights and social justice, bridging the divide between national and international interests. There is a call for social workers to understand the global community that awaits our service. Yet international experiences are not within the grasp of nor embraced by all. Students of color are underrepresented participants in the growing trends of internationalization. Through addressing participation barriers, this article uses a case study approach that emphasizes how a social work program at Howard University designed a mission-guided international service learning model that resulted in increased participation for students of color through multiple strategies, while giving primacy to human rights and social justice.
