Now celebrating its 26th year of existence, the Vietnam Era Twin Registry continues to be one of the largest national samples of adult twins in the United States. The Registry twin member population is composed of 7,369 US male–male twin pair Veterans (14,738 total individuals) who served on active duty in the military during the Vietnam conflict (1964–1975). The Registry also maintains a register, data repository, and a biospecimen repository. Details on the operations of the Registry are described, as well as an overview of specific studies. Registry maintenance activities are also described, including the updating of contact information and vital status. Future plans include expanding the biospecimen repository and obtaining input from twins about study methods and diseases and conditions they would like to see investigated.

Before President John Adams appointed him as Chief Justice of the United States in 1801, John Marshall was a soldier, a state legislator, a federal legislator, an envoy to France, and the Secretary of State. He also maintained a thriving practice in Virginia and federal courts, occasionally teaming up with political rival and personal friend Patrick Henry. Forty-five years old at the time of his appointment to the Supreme Court, Marshall has been serving his state and his country for a quarter century before he took judicial office. Marshall is an exemplar of professional excellence for all lawyers and judges. But one looking for life lessons in the law from the life of John Marshall should not neglect his time as a soldier, before he became a lawyer.

Our work assessed the accuracy of the original zygosity classification in the Vietnam Era Twin (VET) Registry using new information from DNA markers on a subset of participants. We then constructed an updated zygosity classification algorithm. The VET Registry includes 7,375 male–male twin pairs who served in the military during the Vietnam era. During the mid-1980s 4,774 twin pairs completed a zygosity questionnaire of 20 items. Additionally, military record information, including blood group, was available. Items from the zygosity questionnaire and blood group were used in the original zygosity classification. Between 1990–2009 DNA was obtained from 612 twin pairs and concordance between co-twins was used to classify zygosity. Next logistic regression was used to construct predicted probabilities of zygosity using items from the zygosity questionnaire with this subsample. All twins were reclassified according to the new zygosity prediction model and compared with the original zygosity assignment. The original and new predicted probabilities of zygosity were highly correlated (r= 0.962) and concordance for the classification of zygosity was similarly high (kappa = 0.936). Errors in the original zygosity assignment were primarily due to monozygotic twins that were misclassified as dizygotic based on military record blood group data. Removing the military record blood group data markedly improved the accuracy of the original classification. Zygosity assignment based on a zygosity questionnaire was highly predictive of DNA-based zygosity. Augmentation of such a zygosity classification from administrative data, military records, or other records, should be done with caution.

AbstractA Vietnam Era (1964-1975) Twin Registry of American male-male veterans born between 1939 and 1955 has been developed to provide a study sample for research evaluating the impact of Vietnam service on the medical and psychosocial aspects of health. In preparation for developing the Registry, several alternative sources of twins and methods for identifying twins were investigated. A computerized database of veterans discharged from the military after 1967 was selected as the source because it contains about 50% of the total Vietnam era veteran population, is reasonably unbiased, and provides a feasible method for identifying twins. Twins were identified using an algorithm which involved matching entries on the database for same last name, different first name, same date of birth, and similar social security number. Twin status was confirmed by review of military records. The registry, now complete, is composed of 7,400 twin pairs. It will be an important resource for future research projects.

AbstractAn examination of ascertainment bias in identification of twin pairs in the Vietnam Era Twin Registry has been conducted. A complete listing of all male-male Vietnam era veteran twin pairs born in Connecticut between 1939 and 1955 was obtained (N = 150). An attempt was made to match these pairs with a listing of Vietnam era veteran twin pairs derived from the United States Department of Defense's Defense Manpower Data Center (DMDC) computer files. The results indicate that the DMDC files identified only 46.7% of the 150 Connecticut born Vietnam era veteran pairs. Statistically significant differences (P < 0.05) between pairs found on the DMDC files and Connecticut veteran pairs missing from the DMDC files are observed for the following variables: a) year of discharge from military service, b) total length of active military service, c) branch of service, and d) foreign service. No consistent pattern of bias is observed for factors related to the physical and psychosocial healt of veteran pairs. The implications of the ascertainment biases in the Vietnam Era Twin Registry are discussed.

Subject. In the twentieth century, the most developed countries formed a permanent military economy represented by military-industrial complexes, which began to perform almost a system-forming role in national economies, acting as the basis for ensuring national security, and being an independent military and political force. The United States is pursuing a pronounced militaristic policy, has almost begun to unleash a new "cold war" against Russia and to unwind the arms race, on the one hand, trying to exhaust the enemy's economy, on the other hand, to reindustrialize its own economy, relying on the military-industrial complex. Objectives. We examine the evolution, main features and operational distinctions of the military-industrial complex of the United States and that of the Russian Federation, revealing sources of their military-technological and military-economic advancement in comparison with other countries. Methods. The study uses military-economic analysis, scientific and methodological apparatus of modern institutionalism. Results. Regulating the national economy and constant monitoring of budget financing contribute to the rise of military production, especially in the context of austerity and crisis phenomena, which, in particular, justifies the irrelevance of institutionalists' conclusions about increasing transaction costs and intensifying centralization in the industrial production management with respect to to the military-industrial complex. Conclusions. Proving to be much more efficient, the domestic military-industrial complex, without having such access to finance as the U.S. military monopolies, should certainly evolve and progress, strengthening the coordination, manageability, planning, maximum cost reduction, increasing labor productivity, and implementing an internal quality system with the active involvement of the State and its resources.

Central Asia in recent history is a vast region with five Muslim States-new actors in modern international relations. The countries of Central Asia, having become sovereign States, at the turn of the XX–XXI centuries are trying to peaceful interaction not only with their underdeveloped neighbors, but also with the far-off prosperous West. At the same time, the United States and Western European countries, in their centrosilic ambitions, seek to increase their military and political presence in Central Asia and use the military bases of the region’s States as a springboard for supplying their troops during anti-terrorist and other operations. With the active support of the West, the Central Asian States were accepted as members of the United Nations. For monitoring and exerting diplomatic influence on the regional environment, the administration of the President of the Russian Federation H. W. Bush established U.S. embassies in all Central Asian States. Turkey, a NATO member and secular Islamic state, was used as a lever of indirect Western influence over Central Asian governments, and its model of successful development was presented as an example to follow.
