Cognitive ability as a mediator of GxSES interactions along the educational life course

A growing body of research asks whether the opportunity to realize the genetic endowment for education varies by parental socio-economic status (GxSES). While the behavioral genetic Scarr-Rowe hypothesis (SRH) suggests stronger, the sociological compensatory advantage hypothesis (CAH) predicts weaker genetic effects for individuals with a higher social origin. Using data from the German TwinLife survey, I estimate biometric twin models to test for a GxSES along the educational life course and whether it can be explained by a moderation of the effect of genes associated with cognitive ability. While for secondary school track no GxSES can be found, there is a GxSES for tertiary enrolment in line with the CAH that is mainly accounted for by social origin differences in the realization of genes associated with cognitive ability. Taken together, the results show a more pronounced GxSES pattern in the later educational life course.

Not by g alone: The benefits of a college education among individuals with low levels of general cognitive ability

In a longitudinal sample of 2593 individuals, we investigated the frequency individuals with IQs ≤ 90 completed college and whether these individuals experienced the same social and economic benefits higher-IQ college graduates did. Although the majority of individuals with IQs ≤ 90 did not have a college degree, approximately one in three women and one in five men did. The magnitude of the college effect on occupational status, income, financial independence and law abidingness was independent of IQ level, a finding replicated using the longitudinal NLSY97 sample. Additional analyses suggested the association of college with occupational status was causal and that the educational success of individuals with low average IQs may depend on personality factors, family socioeconomic status and genetic endowment. We discuss our finding in the context of the recent expansion in college attainment as well as the dearth of research on individuals with low average IQs.

Microbiome, Immunosenescence, and Chronic Kidney Disease

The gut microbiome is known as an important predictive tool for perceiving characteristic shifts in disease states. Multiple renal diseases and pathologies seem to be associated with gut dysbiosis which directly affects host homeostasis. The gastrointestinal-kidney dialogue confers interesting information about the pathogenesis of multiple kidney diseases. Moreover, aging is followed by specific shifts in the human microbiome, and gradual elimination of physiological functions predisposes the microbiome to inflammaging, sarcopenia, and disease. Aging is characterized by a microbiota with an abundance of disease-associated pathobionts. Multiple factors such as the immune system, environment, medication, diet, and genetic endowment are involved in determining the age of the microbiome in health and disease. Our present review promotes recently acquired knowledge and is expected to inspire researchers to advance studies and investigations on the involved pathways of the gut microbiota and kidney axis.

Injuries resulting from practicing performance sports in table tennis and tennis

Performance sport as an area of human excellence requires, besides an over-average genetic endowment of motor skills, a huge workload of high intensity, which causes the wear of the body systems of the athletes, especially the osteo-musculo-articular. The high ball movement speed for rocket and paddle sports disciplines such as table tennis and field tennis, intensively demands the performance of the body of practitioners when performing specific technical tactics, especially the technical elements of the attack, such as topspin or smash. Based on the theoretical documentation, I noticed an acute condition in the scapulo-humeral joint 21.05%, at the lumbar level 15.79% and 13.16% in the ankle joint in the table tennis and in the field tennis as percentages at scapulo-humeral joint 13.85%, lumbar 15.38% and 20.00% ankle joint, aspects that validate our desire to improve the quality of life of practicing athletes of the two disciplines through a program of amelioration of compensatory nature.The objective of this theoretical research is to identify the areas subject to mechanical stress with high risk of wearor injury from the two "sister" sports disciplines.Tasks: Critical analysis of a larger volume of studies conducted on the direction of our research interest.Purpose: obtaining the information necessary which would highlight the risks the performance athletes, practitioners of the two disciplines, are subjected to, as well as gaining knowledge on tennis and table tennis.

Practical-Methodical Aspects Regarding the Training of the Fencers Aged 8 to 10 Years

This paper investigates the theoretical, tactical and physical training level specific to the fencer of 8 to 10 years old. The study was conducted in Bucharest Technical Applied Sports Club (foil fencing), in the gym of the Secondary School no 167, with a group of 10 athletes aged 8 to10 years. The study results show the improvement of the specific technical and physical indicators and also of the performance level reached in direct competition. The high values of these indicators reveal a closed connection between the physical training and the technical-tactical one during the fencing sessions. The technicaltactical tests and the competition have values that improved differently for each athlete. This is due to the physical and technical training exercises but especially to the temperamental type of the athletes. The technique, tactics and competition results are influenced by the workouts and particularly by the genetic endowment of each athlete.

Preparing the Child for Productive Life

The nature of children’s development is greatly influenced by the environmental conditions in which they are brought up. The amount of social stimulation which they receive is of particular importance, and even if physical conditions are adequate, an unstimulating environment which provides with little opportunity or need to experiment or solve problems will result in low level of achievement. Perhaps the most important aspect of the child’s social development is beyond the reach of the teacher. For the first very important aspect of the child’s development lies in the home. Genetic endowment and cultural level of the family, coupled with the actual physical conditions of the home will have decisive effect on the child’s development and will continue to influence him throughout his school life. These factors are inaccessible to be influenced by the teacher but it is as well for him to have them in mind in his dealings with pupils. In addition, he will need to know how he may most effectively change his pupils along the lives he considers to be the most appropriate. That is, he will seek out the most efficient ways of getting pupils learn for productive life in future. The topic under review will be approached from various fronts which include; The Sociological and Philosophical models; role of the school; Learners’ responsibility; role of the teacher; discipline and learner control; role of the parent; guidance and counseling services and conclusion.

Association of genetic and behavioral characteristics with the onset of diabetes

Background Prior work has established sociodemographic, lifestyle, and behavioral risk factors for diabetes but the contribution of these factors to the onset of diabetes remains unclear when accounting for genetic propensity for diabetes. We examined the contribution of a diabetes polygenic score (PGS) to the onset of diabetes in the context of modifiable known risk factors for diabetes. Methods Our sample consisted of 15,190 respondents in the United States-based Health and Retirement Study, a longitudinal study with up to 22 years of follow-up. We performed multivariate Cox regression models stratified by race (non-Hispanic white and non-Hispanic black) with time-varying covariates. Results We observed 4217 (27.76%) cases of incident diabetes over the survey period. The diabetes PGS was statistically significantly associated with diabetes onset for both non-Hispanic whites (hazard ratio [HR] = 1.38, 95% confidence interval [CI] = 1.30, 1.46) and non-Hispanic blacks (HR = 1.22, 95% CI = 1.06, 1.40) after adjusting for a range of known risk factors for diabetes, highlighting the critical role genetic endowment might play. Nevertheless, genetics do not downplay the role that modifiable characteristics could still play in diabetes management; even with the inclusion of the diabetes PGS, several behavioral and lifestyle characteristics remained significant for both race groups. Conclusions The effects of genetic and lifestyle characteristics should be taken into consideration for both future studies and diabetes management.
