The objective of the present study was to investigate the inter-relationships between nutritional status (past and current nutrition), brain development, and scholastic achievement (SA) of Chilean high-school graduates from high and low intellectual quotient (IQ) and socio-economic status (SES) (mean age 18.0 (SD 0.9) years). Results showed that independently of SES, high-school graduates with ...

CONTEXT Longitudinal studies indicate that a lower IQ score increases risk of schizophrenia. Preliminary evidence suggests there is no such effect for nonpsychotic bipolar disorder. To our knowledge, there are no prior population-based, longitudinal studies of premorbid IQ score and risk of developing severe depression requiring hospital admission. OBJECTIVES To investigate the association be...

We review new findings and new theoretical developments in the field of intelligence. New findings include the following: (a) Heritability of IQ varies significantly by social class. (b) Almost no genetic polymorphisms have been discovered that are consistently associated with variation in IQ in the normal range. (c) Much has been learned about the biological underpinnings of intelligence. (d) ...

In this paper we merge three datasets individual income data, patenting data, and IQ data to analyze the deterninants of an individual’s probability of inventing. We find that: (i) parental income matters even after controlling for other background variables and for IQ, yet the estimated impact of parental income is greatly diminished once parental education and the individual’s IQ are controll...

Humane-egalitarian ideals, whose aims are group justice and reducing environmental inequality and privilege, must be tested against reality, as revealed by psychology and other social sciences. Four issues are addressed: the equation between IQ and intelligence, whether group potential is determined by a group's mean IQ, whether the BlackWhite IQ gap is genetic, and the meritocratic thesis that...

The Duchenne muscular systrophy (DMD) is a muscular dystrophy with cognitive impairment present in 20-30% of the cases. In the present study, in order to study the relationship between the α-dystroglycan (α-DG) immunostaining in skeletal muscle and cognitive performance in DMD patients, 19 were assessed. Twelve patients performed the intelligence quotient (IQ) below the average. Among the 19 pa...

This research maps the information quality (IQ) process and finds that the control constituent of the process comprises two types of factors: IQ dimensions and IQ indicators. The later forms an information performance measure known as ‘information orientation’ that measures the capability of an organisation to effectively manage and use information. It stressed that the consistency between the ...

OBJECTIVE To examine direct and mediated effects of maternal IQ, marital status, family income, and quality of the home environment on the cognitive development of low birthweight infants. METHODS Secondary analyses on a large dataset using hierarchical regression identified factors correlated with cognitive outcomes in children at 3 years of age who were born at low birthweight. RESULTS Ma...

Zero-IF receivers are gaining interest because they enable low-cost WLAN OFDM terminals. However, Zero-IF receivers introduce IQ imbalance which may have a huge impact on the performance. Rather than increasing component cost to decrease the IQ imbalance, an alternative is to tolerate the IQ imbalance and compensate it digitally. Current solutions converge too slow for bursty WLAN communication...
