In Search of Theory Development in Grounded Investigations: Doctors' Experiences of Managing as an Example of Fitted and Prospective Theorizing 总被引:1,自引:0,他引:1
This article draws on a study of doctors’ experiences of clinical managing to highlight research conventions that limit the development and use of middle range theories in grounded studies. Using sensemaking and the psychological contract as example frameworks, we illustrate how customary deductive evaluations of middle range theories turn grounded researchers away from theory building. As a correction to these conventions, we offer an inductive approach to building existing theory in grounded investigations that does not depend solely on working with frameworks under different empirical conditions. We suggest that forward theorizing is most likely to progress from a synthesis of fitted explanation and prospective thinking that presses at the limits of the data's usefulness. To illustrate this approach, trialled thinking about novel theoretical juxtapositions and alternative sources was used in conjunction with our clinical director data. The value of this approach was supported in two ways. First, a number of fitted and prospective conjectures are offered about how social identity articulates with psychological contracts and sensemaking in role change situations. Second, new light is shed on the process by which particular social conditions differentially modify employees’ social categorizations, and how these inform employee responses to the evolving experience of role change. The article concludes with some tentative proposals for promoting more discussion of theory building in grounded investigations. 相似文献

How do macro variables such as aggregate consumption, aggregate money demand, prices, and interest rates vary in response to government attempts to redistribute income across agents through selective tax-transfer policies? This question is investigated for an overlapping generations model consisting of heterogeneously endowed three-period lived agents. In the presumably most favorable case for invariance (identical log-linear utility functions), it is shown that positive interest rate macro equilibria are invariant with respect to redistributions in social security benefits if and only if all agents initially exhibit qualitatively identical liquidity preference behavior, i.e. positive money holding only in youth, only in middle-age, or never. 相似文献

Summary An Arrovian social choice rule is a social welfare function satisfying independence of irrelevant alternatives and transitivity of social preference. Assume a measurable outcome spaceX with its (Lebesgue) measure normalized to unity. For any Arrovian rule and any fractiont, either some individual dictates over a subset ofX of measuret or more, or at least a fraction 1–t of the pairs of distinct alternatives have their social ordering fixed independently of individual preferences. Also, for any positive integer (less than the total number of individuals), there is some subsetH of society consisting of all but persons such that the fraction of outcome pairs (x, y) that are social ranked without consulting the preferences of anyone inH, whenever no individual is indifferent betweenx andy, is at least 1–1/4.We are grateful to Roy Mathias and Daniel Waterman for help with some technical matters, and to chairman Jim Follain and the Syracuse University Economics Department for financing the exchange that launched this project.

We derive the formula for the unilateral price effects of mergers of two products with linear demand in the general asymmetric situation. The formula uses the same information required to calculate upward pricing pressure in the 2010 Horizontal Merger Guidelines. 相似文献

Abstract. This paper explores the extent to which majority rule is invulnerable to manipulation by individuals and coalitions, even
when majority rule is used to select more than one alternative. The resulting rule may or may not be strategy-proof, depending
on the size of the coalitions that can form, and on the nature of the individual preferences over sets of alternatives. No
individual can manipulate with respect to a wide family of preferences over sets. The only restriction on the domain of true and revealed
individual preferences is that the selection rule is always well defined.

This paper generalizes existing econometric models for censored competing risks by introducing a new flexible specification based on a piecewise linear baseline hazard, time‐varying regressors, and unobserved individual heterogeneity distributed as an infinite mixture of generalized inverse Gaussian (GIG) densities, nesting the gamma kernel as a special case. A common correlated latent time effect induces dependence among risks. Our model is based on underlying latent exit decisions in continuous time while only a time interval containing the exit time is observed, as is common in economic data. We do not make the simplifying assumption of discretizing exit decisions—our competing risk model setup allows for latent exit times of different risk types to be realized within the same time period. In this setting, we derive a tractable likelihood based on scaled GIG Laplace transforms and their higher‐order derivatives. We apply our approach to analyzing the determinants of unemployment duration with exits to jobs in the same industry or a different industry among unemployment insurance recipients on nationally representative individual‐level survey data from the US Department of Labor. Our approach allows us to conduct a counterfactual policy experiment by changing the replacement rate: we find that the impact of its change on the probability of exit from unemployment is inelastic.

Repeated exposure to a music video was found to forestall wear out relative to repetitive exposure to the music only. Susceptibility to wear out in the case of the music video was further reduced by eliminating the closure associated with the story told by the video. The level of positive cognitive responses was posited as a mediator to help explain the observed results. © 1993 John Wiley & Sons, Inc. 相似文献
