The system of veterinary and sanitary measures in the CJSC "Makeevo" of the Zarayskiy municipal district of the Moscow region was studied during 2015-2016. The tests were carried out on 2232 cattle with age and sex composition: 965 cows, 206 heifers, 186 heifers (2014 year of birth), 52 bulls (2014 year of birth,) 426 heifers (2015 year of birth), 397 male calves (2015 year of birth). The system of veterinary and sanitary measures to prevent infectious diseases of cattle have been developed on the basis of modern scientific achievements, taking into account many years of practical experience in Russia, includes a set of measures: an analysis of the current situation in the farm; identification of urgent priority measures, specialists training on the farm, monitoring of the proposed measures implementation; elaboration of the farm development plan. The results of the recommendations production tests and the system of veterinary and sanitary measures on number of cattle in the dairy farm enterprise through the modernization of the production process are presented. Application of organizational-economic, sanitary, diagnostic, preventive and therapeutic measures was allowed to protect 99.25% of animals from necrobacteriosis.

The hypothesis that the sex composition of an applicant pool affects the hiring probabilities of individual job applicants was tested using gender-distinctive information on accepted and rejected job applicants in The Netherlands. The evidence supports this hypothesis, although the effect sizes are moderate. Both men and women have a lower probability of being hired when the applicant pool contains fewer applicants from their own sex.

AbstractThe extent to which population demography determines the age and sex composition of primate groups was examined using data from a population of wedge-capped capuchin monkeys Cebus olivaceus in central Venezuela. Demographic parameters were derived from censuses of individually recognized, aged, and sexed individuals living in nine groups over a ten year period. Animals were aged by extrapolation from census data. Animals of both sexes were classed as infants during their first year, and juveniles until they reached six years of age. Females reach sexual maturity at this time, while males were classed as subadults until they reached full adult size at age 12. Adulthood lasts at least 30 years in females, at least 24 years in males. Age-sex class specific mortality and fecundity rates generated a life table which indicated that the population was increasing (r = 0.087) between 1977 and 1986. The age and sex composition of the nine groups was described annually. On average, non-adults made up 60% of a group, with this percentage increasing with group size. There were more females than males in all groups in all years. The strong female-biased adult sex ratio (1:4.4) was a consequence of a biased birth sex ratio (1:1.9), higher female than male survivorship especially between the ages of 3 and 7 when males were dispersing, and a pronounced sexual bimaturism. The stable age distribution derived from the life table successfully predicted the observed average distribution of age-sex categories in groups. This suggests that the group structure of Cebus olivaceus groups is not a consequence of intragroup social interactions, but results from demographic parameters.
