General location transform of the order statistics from the exponential,pareto and weibull,with application to maximum likelihood estimation

Based one some common distribution properties of the order statistics and the transformation theory by Efron(1982), we determine unified explicit general location transformations, which map the distributions of the order statistics from the Exponential, Pareto and Weibull to a standard normal distribution. This result is used to derive analytical formulas for the maximum likelihood estimators of the shape parameter of these distributions of order statistics. The presented exact method is applied to catastrophe earthquake life reinsurance.     

Institutionalizing Scientific Knowledge: The Social and Political Foundation of Empirical Economic Research

Scientific knowledge is an essential component of modern society. Consequently, sociologists are interested in its production process and have conducted a broad variety of studies showing how social patterns influence the definition and the boundaries of scientific knowledge. In this paper, I ask how social factors influence the transformation of a ‘normal’ field of knowledge into a ‘scientific’ one. First, I give a brief overview of the development of the sociology of scientific knowledge exploring different approaches to the social foundations and boundaries of scientific knowledge. Second, I present a case study of the transformation of empirical economic research in the 1920s from a field of knowledge produced by journalists and civil servants into a prestigious scientific domain. I use neo‐institutionalist ideas to show that knowledge needs a socially legitimated organizational frame in order to count as ‘scientific’ and I examine how political needs to ‘manage the economy’ build boundaries around economic knowledge and define it as ‘scientific’ in order to control its production, distribution, and communication.     

Infant Auditory Sensitivity to Pure Tones and Frequency‐Modulated Tones

It has been suggested that infants respond preferentially to infant‐directed speech because their auditory sensitivity to sounds with extensive frequency modulation (FM) is better than their sensitivity to less modulated sounds. In this experiment, auditory thresholds for FM tones and for unmodulated, or pure, tones in a background of noise were measured for 4‐month‐old infants using a conditioned response procedure. The FM tones swept from 150 to 275 Hz or from 150 to 550 Hz. The frequency of the pure tone was either 275 or 550 Hz. The results showed that infants were slightly, but significantly, more sensitive to the sounds that included 550 Hz than they were to the lower frequency sounds, whether or not the sound was frequency modulated. It appears that infants could be somewhat more sensitive to infant‐directed than to adult‐directed speech, not because of FM per se, but because the fundamental frequency excursions in infant‐directed speech extend into a higher frequency range than those in adult‐directed speech.     

Invariant structures of prognosis curves in Forrester's World Dynamics

This paper deals with some results of various simulations with Forrester's World Dynamics. These simulations concern the temporal and quantitative fixing of limits in relation to initial values and deal with the effects of specific table functions in this model. In addition, they also treat the behavior of the curves in approaching the limits.     

Buying a pig in a poke: An experimental study of unconditional veto power

We study an ultimatum experiment in which the responder does not know the offer when accepting or rejecting. Unconditional veto power leads to acceptances, although proposers are significantly greedier than in standard ultimatum games, and this is anticipated by responders. We also elicit responders’ willingness to pay for (un)conditional veto power. The bids reveal a large endowment effect.

Manpower Planning in Social Welfare

The discipline of history has been much neglected in curriculum planning in schools of social work at every level—undergraduate, MSW and Ph.D. The study of history may recover lost experiments in social service; it may provide the student with methods relevant to social analysis; it may provide models for apprentice social workers; and it may provide insights into social process.     

The Effects of United Way Membership on Employee Pay in Nonprofit Organizations

This research investigates the relationship between United Way membership and the compensation level of employees in nonprofit organizations. This study is based on questionnaires completed by 1,811 employees from sixty‐nine nonprofit agencies in a large metropolitan area. Managerial capitalism, agency theory, and United Way funding and governance roles were used to develop the hypotheses. We found that employees of organizations belonging to the United Way receive pay premiums, suggesting that the United Way member agencies are higher‐quality agencies that pay their employees higher wages.
