The age dynamics of milk productivity of cows has been studied. It has an unequal character depending on the lineage and individual characteristics of the breeding bulls. This must be taken into account when predicting the effect of selection for these traits.

This preliminary study identifies individual characteristics and job features that significantly influence the selection of meat for breakfast and lunch by truck drivers in Kenya. Based on the survey data collected in July 2017, two equations are estimated using the logit technique. Results show that individual characteristics drive the choice of non-meat foods for breakfast, while job features and environment encourage meat selection for lunch. Having formal education lowers the probability of choosing meat for either meal, but taking hitchhikers strongly encourages eating meat for lunch, likely due to the additional income from fees paid by travelers to the driver.

The article deals with the issues of professional psychological selection in the internal Affairs bodies as an integral part of the system of measures to prevent professional deformation in service collectives. The implementation of the measures organized on the basis of monitoring of data received by psychologists of internal Affairs bodies is aimed at maintaining and improving the efficiency of the police. The purpose of this area of work of psychologists is to equip police service teams with reliable employees who meet the requirements of the modern legal state. The presented materials consider the practice of implementing by police psychologists the decree Of the Government of the Russian Federation dated December 06, 2012 No. 1259 «on approval of the Rules of professional psychological selection for service in the internal Affairs bodies of the Russian Federation». The materials are consistent with the results of research conducted by Russian and foreign researchers. The conclusions are based on a comparative analysis of the results of the work of the Commission on psychological selection of the regional Department of the Ministry of internal Affairs. Describes some of the individual characteristics of the persons who were refused admission to the service. Individual factors that hinder the process of effective adaptation in service teams are listed, as well as the role of early maladaptive schemes in the process of adaptation. Individual and environmental factors of influence on the formation and development of deforming influence on employees in the course of performance of official activities are presented, based on the analysis of incidents that occurred in collectives in the period 2018–2020. The article deals with the actual difficulties of practical implementation of psychological selection for service as the basis for early prevention of professional deformation in the service collectives of internal Affairs bodies.

During its formation and improvement, cattle acquired a number of biological and economic-useful qualities, which allowed identifying separate groups of animals with high productivity and productive longevity. One of the main criteria for cow selection for further breeding is the quantity and quality of dairy products [4]. Profitability of dairy farming largely depends on both milk yield and the reproductive ability of cows. Troubled calving and subsequent diseases and complications affect the state of the animal organism; preservation and restoration of the health of a cow after troubled calving require considerable expenses. This research was aimed at examining milk production in cows with easy and troubled calving. To achieve this goal, in the studied number of cows with easy and troubled calving, the authors analyzed the following parameters: milk yield during the first lactation, fat and protein mass fraction, the amount of milk fat and milk protein; milk productivity was also studied, depending on the age at first insemination and the duration of the service period. It has been found that milk yields in the cows with troubled calving were higher than in the cows with easy calving. The influence of the age at the first fruitful insemination on the further milk productivity has been determined: the highest yields were obtained from the cows with the age at the first fruitful insemination in the interval between 15.1 and 17.0 months. The maximum milk yields during the first lactation – 6,206 kg - were observed in the cows with relatively short service period (61 to 90 days).

Purpose Although repetitive speech is a hallmark characteristic of autism spectrum disorder (ASD), the contributing factors that influence repetitive speech use remain unknown. The purpose of this exploratory study was to determine if the language context impacts the amount and type of repetitive speech produced by children with ASD. Method As part of a broader word-learning study, 11 school-age children with ASD participated in two different language contexts: storytelling and play. Previously collected language samples were transcribed and coded for four types of repetitive speech: immediate echolalia, delayed echolalia, verbal stereotypy, and vocal stereotypy. The rates and proportions of repetitive speech were compared across the two language contexts using Wilcoxon signed-ranks tests. Individual characteristics were further explored using Spearman correlations. Results The children produced lower rates of repetitive speech during the storytelling context than the play-based context. Only immediate echolalia differed between the two contexts based on rate and approached significance based on proportion, with more immediate echolalia produced in the play-based context than in the storytelling context. There were no significant correlations between repetitive speech and measures of social responsiveness, expressive or receptive vocabulary, or nonverbal intelligence. Conclusions The children with ASD produced less immediate echolalia in the storytelling context than in the play-based context. Immediate echolalia use was not related to social skills, vocabulary, or nonverbal IQ scores. These findings offer valuable insights into better understanding repetitive speech use in children with ASD.

Purpose Nearly 50% of school-based speech-language pathologists (SLPs) provide services to school-age children who use augmentative and alternative communication (AAC). However, many SLPs report having insufficient knowledge in the area of AAC implementation. The objective of this tutorial is to provide clinicians with a framework for supporting 1 area of AAC implementation: vocabulary selection for preliterate children who use AAC. Method This tutorial focuses on 4 variables that clinicians should consider when selecting vocabulary: (a) contexts/environments where the vocabulary can be used, (b) time span during which the vocabulary will be relevant, (c) whether the vocabulary can elicit and maintain interactions with other people, and (d) whether the vocabulary will facilitate developmentally appropriate grammatical structures. This tutorial focuses on the role that these variables play in language development in verbal children with typical development, verbal children with language impairment, and nonverbal children who use AAC. Results Use of the 4 variables highlighted above may help practicing SLPs select vocabulary that will best facilitate language acquisition in preliterate children who use AAC.

Abstract For adults with acquired communication impairment, particularly those who have communication disorders associated with stroke or neurodegenerative disease, communication partners play an important role in establishing and maintaining communicative competence. In this paper, we assemble some evidence on this topic and integrate it with current preferred practice patterns (American Speech-Language-Hearing Association, 2004). Our goals are to help speech-language pathologists (SLPs) identify and describe partner-based communication strategies for adults with acquired impairment, implement evidence-based approaches for teaching strategies to communication partners, and employ a Personnel Framework (Binger et al., 2012) to clarify partners? roles in acquiring and supporting communication tools for individuals with acquired impairments. We offer specific guidance about AAC techniques and message selection for communication partners involved with chronic, degenerative, and end of life communication. We discuss research and provide examples of communication partner supports for person(s) with aphasia and person(s) with amyotrophic lateral sclerosis who have complex communication needs.
