"Birth-order effects are posited by many to affect earnings and schooling. We show how such effects can be interpreted to shift either the earnings possibility frontier for siblings or parental preferences. We find empirical evidence for birth-order effects on (age-adjusted) schooling and on earnings for young U.S. adults, though the ...

The annual birth cycle in rural Egypt peaks in December and has two distinguishable minima in June and September. This pattern bears a striking inverse resemblance to the seasonal movements of employment and wages. Infant and child mortality and marriage also display stable, though different seasonal patterns. The paper explores ...

Studies investigating the association between the risk of schizophrenia and season of birth are reviewed and the association clearly established. This association cannot be explained on the basis of age-incidence or age-prevalence artifacts. Other studies suggest there may be an association between bipolar disorder and season of birth. The leading ...

The cause of the deaths of bony bream and other native fish in the Finke River near Alice Springs in winter 1984 was infection with the protozoan ciliate Chilodonella hexasticha. The parasites induced severe generalised epithelial hyperplasia in the gills, which would have compromised respiratory exchange and killed the fish ...
Ede A - - 1985
The usual inverse relationship between temperature of month and number of births in that month for persons later given a schizophrenic diagnosis was not found in Alberta, Canada. Since the absence of such an inverse relationship has also been noted in northern Sweden, it is suggested that the atypical pattern ...

Probationers ordered to pay restitution were classified by Kohlberg's Stages of Moral Development in order to (a) identify background correlates of moral development; (b) explore the relation between moral development and restitution compliance; and (c) differentially identify facilitating circumstances of restitution. The research was conducted in Albuquerque, New Mexico, from ...
Gowers S - - 1985
A retrospective case-notes study of 252 patients was undertaken, to focus on their birth order, and other aspects of their sibships. There is little evidence of a relationship to birth order using an established measure (Slater, 1962). Previous researchers have found a preponderance of female siblings in the families of ...

The results of research on infants at high risk for schizophrenia (offspring of schizophrenic parents) are reviewed. The findings indicate that high-risk infants are not exposed to greater exogenous stress during the prenatal and perinatal periods, although subsequent caregiving provided by disturbed mothers may be nonoptimal. Several findings point to ...

The birth prevalence of CNS malformations in the region of Krakow from 1979 to 1981 was determined to be 1.26/1000 from records of all live- and still-birth deliveries. The frequency of anencephaly was 0.23/1,000; spina bifida and encephalocele, 0.70/1000; isolated hydrocephaly, 0.26/1,000; and other CNS anomalies, 0.06/1,000. The observed rates ...
Jongbloet P H - - 1982
The total number of births and the anencephaly incidence rate in the Netherlands, in the years 1951 to 1968 (both corrected to estimate the 'conception' curves), were analyzed to find their circannual fluctuations and to see whether there was a relation between the two. The results indicate that, as predicted ...

By the study of hereditary serum protein markers in psychotic patients and normal controls, a surplus of Gc 1-1 (p less than 0.01) and transferrin B variants (p less than 0.0027) has been established in schizophrenias. Affective psychoses are characterized by an excess of the haptoglobin (Hp) serum type 2-2 ...
Brodsky P - - 1981
A theoretical model of the etiology of schizophrenia, the schizophrenia spectrum, and normal development is proposed. This model is based upon replicated research. A selected review of the literature on the etiology of schizophrenia indicated that schizophrenia may be a developmental disorder of the quality of attachment interacting with the ...
