Narrative configuration in qualitative analysis

Abstract: Narrative inquiry refers to a subset of qualitative research designs in which stories are used to describe human action. The term narrative has been employed by qualitative researchers with a variety of meanings. In the context of narrative inquiry, narrative refers to a discourse form in which events and happenings are configured into a temporal unity by means of a plot. Bruner (1985) designates two types of cognition: paradigmatic, which operates by recognizing elements as members of a category; and narrative, which operates by combining elements into an emplotted story. Narrative inquiries divide into two distinct groups based on Bruner's types of cognition. Paradigmatic‐type narrative inquiry gathers stories for its data and uses paradigmatic analytic procedures to produce taxonomies and categories out of the common elements across the database. Narrative‐type narrative inquiry gathers events and happenings as its data and uses narrative analytic procedures to produce explanatory stories.

Integration of visual and linguistic information in spoken language comprehension

Abstract: Psycholinguists have commonly assumed that as a spoken linguistic message unfolds over time, it is initially structured by a syntactic processing module that is encapsulated from information provided by other perceptual and cognitive systems. To test the effects of relevant visual context on the rapid mental processes that accompany spoken language comprehension, eye movements were recorded with a head-mounted eye-tracking system while subjects followed instructions to manipulate real objects. Visual context influenced spoken word recognition and mediated syntactic processing, even during the earliest moments of language processing.

Periodic boundary conditions in ab initio calculations.

Abstract: The convergence of the electrostatic energy in calculations using periodic boundary conditions is considered in the context of periodic solids and localized aperiodic systems in the gas and condensed phases. Conditions for the absolute convergence of the total energy in periodic boundary conditions are obtained, and their implications for calculations of the properties of polarized solids under the zero-field assumption are discussed. For aperiodic systems the exact electrostatic energy functional in periodic boundary conditions is obtained. The convergence in such systems is considered in the limit of large supercells, where, in the gas phase, the computational effort is proportional to the volume. It is shown that for neutral localized aperiodic systems in either the gas or condensed phases, the energy can always be made to converge as O(${\mathit{L}}^{\mathrm{\ensuremath{-}}5}$) where L is the linear dimension of the supercell. For charged systems, convergence at this rate can be achieved after adding correction terms to the energy to account for spurious interactions induced by the periodic boundary conditions. These terms are derived exactly for the gas phase and heuristically for the condensed phase.

Subcultures of Consumption: An Ethnography of the New Bikers

Abstract: This article introduces the subculture of consumption as an analytic category through which to better understand consumers and the manner in which they organize their lives and identities Recognizing that consumption activities, product categories, or even brands may serve as the basis for interaction and social cohesion, the concept of the subculture of consumption solves many problems inherent in the use of ascribed social categories as devices for understanding consumer behavior This article is based on three years of ethnographic fieldwork with Harley-Davidson motorcycle owners A key feature of the fieldwork was a process of progressive contextualization of the researchers from outsiders to insiders situated within the subculture Analysis of the social structure, dominant values, and revealing symbolic behaviors of this distinct, consumption-oriented subculture have led to the advancement of a theoretical framework that situates subcultures of consumption in the context of modern consumer culture and discusses, among other implications, a symbiosis between such subcultures and marketing institutions Transferability of the principal findings of this research to other subcultures of consumption is established through comparisons with ethnographies of other self-selecting, consumption-oriented subcultures

Emotion Regulation and Mental Health

Abstract: In this article, we argue that emotion regulation is an essential (and traditionally underemphasized) feature of mental health. To develop this idea, we first define the terms emotion, emotion regulation, and mental health. We then chart the development of emotion regulation and describe its role in various facets of normal functioning. Next, we consider what happens when emotion becomes dysregulated in a major depressive episode. We suggest that an emotion regulatory perspective integrates diverse theoretical views of depression and has implications for the assessment, treatment, and prevention of depression. We conclude by speculating about the role of emotion regulation in the broader context of public mental health.

Behavior Problems in Preschool Children: A Review of Recent Research

Abstract: Research on the prevalence, course, and correlates of behavior problems in preschool children was examined. Prospective epidemiological studies and follow-up studies of clinical/high risk samples indicate that serious externalizing problems identified early often persist. Negative, inconsistent parental behavior and high levels of family adversity are associated with the emergence of problems in early childhood and predict their persistence to school age. Studies are examined from a developmental perspective and integrated with research on optimal parent-child relationships. The severity of initial problems and family context are related to different developmental outcomes.

Dissociation of oceanic methane hydrate as a cause of the carbon isotope excursion at the end of the Paleocene

Abstract: Isotopic records across the “Latest Paleocene Thermal Maximum“ (LPTM) indicate that bottom water temperature increased by more than 4°C during a brief time interval (<104 years) of the latest Paleocene (∼55.6 Ma). There also was a coeval −2 to −3‰ excursion in the δ13C of the ocean/atmosphere inorganic carbon reservoir. Given the large mass of this reservoir, a rapid δ13C shift of this magnitude is difficult to explain within the context of conventional hypotheses for changing the mean carbon isotope composition of the ocean and atmosphere. However, a direct consequence of warming bottom water temperature from 11 to 15°C over 104 years would be a significant change in sediment thermal gradients and dissociation of oceanic CH4 hydrate at locations with intermediate water depths. In terms of the present-day oceanic CH4 hydrate reservoir, thermal dissociation of oceanic CH4 hydrate during the LPTM could have released greater than 1.1 to 2.1 × 1018 g of carbon with a δ13C of approximately −60‰. The release and subsequent oxidation of this amount of carbon is sufficient to explain a −2 to −3‰ excursion in δ13C across the LPTM. Fate of CH4 in oceanic hydrates must be considered in developing models of the climatic and paleoceanographic regimes that operated during the LPTM.

Developments in nonholonomic control problems

Abstract: Provides a summary of recent developments in control of nonholonomic systems. The published literature has grown enormously during the last six years, and it is now possible to give a tutorial presentation of many of these developments. The objective of this article is to provide a unified and accessible presentation, placing the various models, problem formulations, approaches, and results into a proper context. It is hoped that this overview will provide a good introduction to the subject for nonspecialists in the field, while perhaps providing specialists with a better perspective of the field as a whole. The paper is organized as follows: introduction to nonholonomic control systems and where they arise in applications, classification of models of nonholonomic control systems, control problem formulations, motion planning results, stabilization results, and current and future research topics.

Log-Periodogram Regression of Time Series with Long Range Dependence

Abstract: This paper discusses the estimation of multiple time series models which allow elements of the spectral density matrix to tend to infinity or zero at zero frequency and be unrestricted elsewhere. A form of log-periodogram regression estimate of differencing and scale parameters is proposed, which can provide modest efficiency improvements over a previously proposed method (for which no satisfactory theoretical justification seems previously available) and further improvements in a multivariate context when differencing parameters are a priori equal. Assuming Gaussianity and additional conditions which seem mild, asymptotic normality of the parameter estimates is established.

Measurement of conditional phase shifts for quantum logic.

Abstract: Measurements of the birefringence of a single atom strongly coupled to a high-finesse optical resonator are reported, with nonlinear phase shifts observed for an intracavity photon number much less than one. A proposal to utilize the measured conditional phase shifts for implementing quantum logic via a quantum-phase gate (QPG) is considered. Within the context of a simple model for the field transformation, the parameters of the "truth table" for the QPG are determined.

Ambiguity Aversion and Comparative Ignorance

Abstract: Decisions under uncertainty depend not only on the degree of uncertainty but also on its source, as illustrated by Ellsberg's observation of ambiguity aversion. In this article we propose the comparative ignorance hypothesis, according to which ambiguity aversion is produced by a comparison with less ambiguous events or with more knowledgeable individuals. This hypothesis is supported in a series of studies showing that ambiguity aversion, present in a comparative context in which a person evaluates both clear and vague prospects, seems to disappear in a noncomparative context in which a person evaluates only one of these prospects in isolation.

A focus+context technique based on hyperbolic geometry for visualizing large hierarchies

Abstract: We present a new focus+context (fisheye) technique for visualizing and manipulating large hierarchies. Our technique assigns more display space to a portion of the hierarchy while still embedding it in the context of the entire hierarchy. The essence of this scheme is to lay out the hierarchy in a uniform way on a hyperbolic plane an d map this plane onto a circular display region. This supports a smooth blending between focus and context, as well as continuous redirection of the focus. We have developed effective procedures for manipulating the focus using pointer clicks as well as interactive dragging, and for smoothly an imating transitions across such manipulation. A laboratory experiment comparing the hyperbolic browser with a conventional hierarchy browser was conducted.

The new competitive landscape

Abstract: Technology is rapidly altering the nature of competition and strategy in the late twentieth century, moving us toward a ‘new competitive landscape’ in the twenty-first century. The new competitive landscape presents new issues, new concepts, new problems and new challenges. This essay examines the broad nature of the technological changes that are occurring and identifies some of the important implications of these changes for strategic management. The purpose of the paper is to stimulate further research into these issues in strategic management and to provide an overall context for the other papers appearing in this special issue.

The New Ecological Paradigm in Social-Psychological Context

Abstract: The New Ecological Paradigm (NEP) scale is the most frequently used measure of environmental concern, but it has not been placed in the context of a social-psychological theory of attitude formation or attitude-behavior relationships. Using data from a northern Virginia sample, this study examines NEP in relation to the variables in a theoretical model of environmental concern. We found that the NEP is indistinguishable from a scale of awareness of consequences (AC) of general environmental conditions, both psychometrically and in terms of its relations to behavioral intentions, but somewhat different in its relations to basic value orientations and sociodemographic variables. We conclude that both NEP and AC measure generalized beliefs about the nature of human-environment interactions-or "folk ecology"—a set of beliefs that may be influenced by social structure and values and that influence attitudes, beliefs, and behavioral intentions regarding specific environmental conditions.

How young and old adults listen to and remember speech in noise

Abstract: Two experiments using the materials of the Revised Speech Perception in Noise (SPIN-R) Test [Bilger et al., J. Speech Hear. Res. 27, 32-48 (1984)] were conducted to investigate age-related differences in the identification and the recall of sentence-final words heard in a babble background. In experiment 1, the level of the babble was varied to determine psychometric functions (percent correct word identification as a function of S/N ratio) for presbycusics, old adults with near-normal hearing, and young normal-hearing adults, when the sentence-final words were either predictable (high context) or unpredictable (low context). Differences between the psychometric functions for high- and low-context conditions were used to show that both groups of old listeners derived more benefit from supportive context than did young listeners. In experiment 2, a working memory task [Daneman and Carpenter, J. Verb. Learn. Verb. Behav. 19, 450-466 (1980)] was added to the SPIN task for young and old adults. Specifically, after listening to and identifying the sentence-final words for a block of n sentences, the subjects were asked to recall the last n words that they had identified. Old subjects recalled fewer of the items they had perceived than did young subjects in all S/N conditions, even though there was no difference in the recall ability of the two age groups when sentences were read. Furthermore, the number of items recalled by both age groups was reduced in adverse S/N conditions. The resutls were interpreted as supporting a processing model in which reallocable processing resources are used to support auditory processing when listening becomes difficult either because of noise, or because of age-related deterioration in the auditory system. Because of this reallocation, these resources are unavailable to more central cognitive processes such as the storage and retrieval functions of working memory, so that "upstream" processing of auditory information is adversely affected.

Transaction Cost Economics

Abstract: Torganization by selectively joinin gl aw, economics, and organization theory. As against neoclassical economics, which is predominantly concerned with price and output, relies extensively on marginal analysis, an dd escribes the firm as a production function (whic hi s a technological construction), transaction cost economics (TCE) is concerned with the allocation of economic activity across alternative modes of organization (markets, firms, bureaus, etc.), employs discrete structural analysis, an dd escribes the firm as a governance structure (which is an organizational construction). Real differences notwithstanding, orthodoxy and TCE are in many ways complements—one being more wellsuited to aggregation in the context of simple market exchange, the other being more well-suited to the microanalytics of complex contracting and nonmarket organization. Ib egin by contrasting the lens of contract (out of which TCE works) with the lens of choice (orthodoxy). Vertical integration, which is the paradigm problem for TCE, i st hen examined .T he operationalization of TCE is discusse di n Section 3. Variations on a theme are sketched in Section 4. Public policy is discussed in Section 5. Concluding remarks follow.

Studying context: a comparison of activity theory, situated action models, and distributed cognition

Abstract: It has been recognized that system design will benefit from explicit study of the context in which users work. The unaided individual divorced from a social group and from supporting artifacts is no longer the model user. But with this realization about the importance of context come many difficult questions. What exactly is context? If the individual is no longer central, what is the correct unit of analysis? What are the relations between artifacts, individuals, and the social groups to which they belong? This chapter compares three approaches to the study of context: activity theory, situated action models, and distributed cognition. I consider the basic concepts each approach promulgates and evaluate the usefulness of each for the design of technology. (http://www.ics.uci.edu/~corps/phaseii/nardi-ch4.pdf)

Lexical chains as representations of context for the detection and correction of malapropisms

Abstract: Natural language utterances are, in general, highlyambiguous, and a unique interpretationcan usuallybe determined only by taking into account the constraining influence of the context in which theutterance occurred. Much of the research in natural language understanding in the last twenty yearscan be thought of as attempts to characterize and represent context and then derive interpretationsthatfit best with that context. Typically, this research was heavy with AI, taking context to be nothing lessthan a complete conceptual understanding of the preceding utterances. This was reasonable, as suchan understanding of a text was often the main task anyway. However, there are many text-processingtasksthatrequireonlya partialunderstandingofthetext, andhencea ‘lighter’representationofcontextis sufficient. In this paper, we examine the idea oflexical chains as such a representation. We showhow they can be constructed by means of WordNet, and how they can be applied in one particularlinguistic task: the detection and correction of malapropisms.A malapropism is the confounding of an intended word with another word of similar sound orsimilar spelling that has a quite different and malapropos meaning, e.g., an ingenuous [for ingenious]machine forpeelingoranges. In thisexample, there isaone-letterdifference betweenthe malapropismand the correct word. Ignorance, or a simple typing mistake, might cause such errors. However, sinceingenuous is a correctly spelled word, traditional spelling checkers cannot detect this kind of mistake.In section 4, we will propose an algorithm for detecting and correcting malapropisms that is based onthe construction of lexical chains.
