Acoustic features of infant crying related to intended caregiving intervention

INFANT AND CHILD DEVELOPMENT, Issue 2 2004
Debra M. ZeifmanArticle first published online: 3 JUN 200
Abstract The present study investigated the acoustic features of crying associated with intended caregiving intervention. One hundred eighty-eight parents (138 females, 50 males) viewed a videotape depicting a healthy 4-week-old infant progressing from fussing to crying over the course of 4 minutes, and indicated if and when they would pick up the infant in a real-life situation. There was a distinct peak in responding corresponding to an increase in duration but not fundamental frequency of the infant's cries. This finding is discussed in terms of the existing empirical literature. It is hypothesized that, whereas frequency may convey information about a newborn's neurological integrity and health status at birth, duration and other acoustical variables provide information about slightly older, normal infants' level of distress.

Personality and anorexia nervosa

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue S1 2005
Stephen A. Wonderlich PhD
Abstract We provided a selective review of the relationship between anorexia nervosa (AN) and personality. They reviewed the existing empirical literature examining the relationship between AN and personality. In spite of continued methodologic challenges related to personality assessment, there appears to be a relatively common phenotype in restricting-type AN characterized by high degrees of obsessionality, restraint, and perfectionism. However, there is also evidence of variability within the AN diagnostic category that is related to personality variables. Importantly, personality variables may significantly predict the course and outcome of AN. Personality variables may be risk factors for AN, consequences of AN, share a common cause with AN, or affect the course and outcome of AN. This literature would be enhanced by the articulation of conceptual models of these relationships that can be empirically tested. © 2005 by Wiley Periodicals, Inc. [source]

ECONOMETRIC MODELS OF ASYMMETRIC PRICE TRANSMISSION

JOURNAL OF ECONOMIC SURVEYS, Issue 2 2007
Giliola Frey
Abstract In this paper, we review the existing empirical literature on price asymmetries in commodities, providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models, type of asymmetries and empirical findings. Relative to the previous literature, this paper is novel in several respects. First, it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices. Second, this paper presents an extension of the traditional distinction between long-run and short-run asymmetries to new categories of asymmetries, such as: contemporaneous impact, distributed lag effect, cumulated impact, reaction time, equilibrium and momentum equilibrium adjustment path, regime effect, regime equilibrium adjustment path. Each empirical study is then critically discussed in the light of this new classification of asymmetries. Third, this paper evaluates the relative merits of the most popular econometric models for price asymmetries, namely autoregressive distributed lags, partial adjustments, error correction models, regime switching and vector autoregressive models. Finally, we use the meta-regression analysis to investigate whether the results of asymmetry tests are not model-invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment. The main results of our survey can be summarized as follows: (i) each econometric model is specialized to capture a subset of asymmetries; (ii) each asymmetry is better investigated by a subset of econometric models; (iii) the general significance of the F test for asymmetric price transmission depends mainly on characteristics of the data, dynamic specification of the econometric model, and market characteristics. Overall, our empirical findings confirm that asymmetry, in all its forms, is very likely to occur in a wide range of markets and econometric models. [source]

Public Capital and Economic Growth: A Critical Survey

PERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue S1 2007
Ward Romp
We first survey the channels through which public capital can conceivably affect growth. We then turn to reviewing the existing empirical literature, and we conclude that although not all studies find a growth-enhancing effect of public capital, there is now more consensus than in the past that public capital furthers economic growth. However, the impact reported by recent studies is not as big as some earlier studies suggested. We conclude with an overview of what is known about the optimality of public capital stocks. [source]
