Consolidation and fragmentation in environmental scanning: A review and research agenda

Environmental scanning is a broadly defined concept, having first received attention from scholars in the late 1960s. Over the years a number of similar and overlapping constructs have emerged in management literature. The aim of this study, via a systematic review and thematic analysis of relevant empirical research, is to consolidate foundation environmental scanning knowledge, demonstrate how scanning research has developed and fragmented over time, and propose an agenda for future research. The first contribution of our review is a new typology of environmental scanning research made up of five discrete research views, which provides a more comprehensive and contemporary overview of the field than previous studies. The second is a proposed agenda for future research that explicitly acknowledges the role of technology, an area that is presently underdeveloped in foundation scanning literature. The third contribution is to signpost future directions for research on scanning and organisational performance using a number of theoretical perspectives. The overall outcome of our review is to move scanning research on from increasingly incremental contributions concerned with context to a place where the changing role of technology and the mechanisms through which environmental scanning contributes to competitive advantage can be more thoroughly understood.     

A Service Provider's Elicitation of Its Customers’ Demand Distributions by a Price Mechanism

In a service environment a service provider needs to determine the amount and kinds of capacity to meet customers’ needs over many periods. To make good decisions, she needs to know the probability distribution of her customers’ demand in each period. We study a situation in which customers’ demand for a given service is random in each period, but inelastic, or modeled well by this assumption, and cannot be delayed to the next period. This article presents a mechanism that allows a service provider to learn the distribution of a customer's demand by offering him a set of contracts through which he can partially prepay for future service for a reduced cost for units of service based on anticipated needs. We describe the form of a set of contracts that will cause the customer to reveal his demand distribution as he minimizes his expected costs. To justify the effort of organizing and offering contracts, we present an application that demonstrates the cost savings to the service provider with better capacity planning using the truthfully elicited distribution.     

Time,housework, and the rest of life

Although time envelops all human activities, only now are social scientists giving attention to this variable. Analysis of how American people spent their time in 1965, 1975, and 1985 from national time-diary studies suggests several current beliefs and conclusions that appear misguided or unsupported. Extending the scope of the discussion to include other aspects of peoples' lives (output, satisfactions) suggests ways in which different allocations of time to activities do and do not reflect the value people place on different groups of activities (i.e., lifestyles). Changes in these indicators of social-psychological life over time are needed to help interpret straightforward data on how people spend time.His research interests include social science measurement and methods as well as the impact of technology on social trends. He received his Ph.D. in Sociology and Mathematical Psychology from the University of Michigan.     

Patterns of development in early empathic behavior: Environmental and child constitutional influences

The second year of life is a period of developmental change and instability in empathic expressions. In this study, we identify specific developmental patterns of global empathy during the second year and investigate maternal style, family environment, and temperamental factors as moderator influences on these patterns of development. The sample consists of 158 children selected from twin pairs whose empathic development had been previously studied at 14 and 20 months of age. Planned comparisons within specific groups (initially high, mid-range, or low empathy) tested the difference between children who changed versus those who remained stable. Maternal style, family climate, and child temperament variables significantly differentiated children among different patterns of development. Child gender was an additional moderator of family influences on development among those children whose empathic responses were initially low. These findings suggest the importance of distinguishing patterns of development based on where in the range of behaviors development is tracked.     

The mental health review board: a new concept for difficult clients.

1. The Mental Health Review Board concept is a hospital systems approach to the difficult client. Board membership varies with each case and includes representation from all areas of the hospital. 2. The Review Board deals with clients who have exhausted the system, are threatening or abusive to staff, and noncompliant with treatment recommendations. 3. The Review Board contract is the "final offer" for treatment and is without input from the client. Terms of the contract are nonegotiable. Noncompliance results in discharge and referral elsewhere.     

The air we breathe

Public attitudes toward smoking are complex, but the facts for businesses are clear. Second-hand smoke is a major health hazard, and the most unhealthy places for second-hand smoke are bars and restaurants. While there is little support for a total smoking ban, selected bans are more popular. Even if new federal rules don't force restaurants to ban smoking, businesses can gain a competitive edge by going smoke-free.     

Confidence to be given findings derived from fixed-period definitions of migration

Some of the errors in measurement of migration and its determinants that occur with the use of fixed-period data are identified. Consideration of this issue yields a typology of studies based on the nature of the determinants related to migration. Sources of distortion are numerated. The logical severity of each distortion is detailed. Use of the typology permits an appraisal of the potential confidence to be given to the validity of findings associated with classes of migration research which use fixed-period data. A test case is examined to illustrate the usefulness of the typology.This research was supported in part by the NSF Grant No. SOC76-81767, for the study, "A Test of Competing Explanations for Migration Differentials." Funds for computer time and technical assistance were also provided by the Department of Sociology, The University of Tennessee, Knoxville.     

Linguistic Labels and Categorization in Infancy: Do Labels Facilitate or Hinder?

Although it is generally accepted that labels facilitate categorization in infancy, recent evidence suggests that infants and young children are more likely to process visual input when presented in isolation than when paired with nonlinguistic sounds or linguistic labels. These findings suggest that auditory input (when compared to a no‐auditory baseline) may hinder rather than facilitate categorization. This study assessed 8‐month‐olds' (n = 191) and 12‐month‐olds' (n = 81) abilities to form categories when images were paired with nonlinguistic sounds, linguistic labels, and when presented in isolation. Overall, infants accumulated more looking when visual stimuli were accompanied by sounds or labels; however, infants were more likely to categorize when the visual images were presented without an auditory stimulus.
