The literature identifies three main types of peer associations: cliques, crowds, and dyadic friendships. When schools create learning communities, an additional type of peer association may emerge that is not based on interactions but instead is based on membership in a shared community. The aim of this study is to qualitatively explore the nature and characteristics of this association, labeled peer bonds. Observational data (n=432) and semi-structured interviews (n=33) were collected in two urban high schools over the course of three academic years. Data were analyzed using the constant comparison method. Findings suggest that there are six characteristics of peer bonds: investment in peer success, shared identity, shared values, pedagogical caring, shared success, and shared failure. The scholarly significance of this study is the expansion of theoretical conceptualizations of peer associations in learning communities while the practical significance is the potential use of a largely underutilized source for academic interventions, peers, by creating school community.

The article presents an analysis of the concept and characteristics of learning communities of teachers, as well as the experience of organizing the activities of various associations of teachers, described in Russian and foreign literature. As a result of theoretical research, the authors identified three models for the creation and development of learning communities of teachers: problem-oriented, communication and mixed. This is the scientific novelty of the work carried out. The practical significance of the study is due to the potential to use models in the design, creation and development of learning communities at the level of a separate school, city, region, etc. It is noted that problem-oriented communities appear when there is a problem, the importance of solving which is recognized by all its participants. The main activities of such communities are Lesson Study and pedagogical supervision. Teachers meet to find a solution to a problem together, jointly develop a plan for the upcoming lesson and reflect on what has taken place. For the emergence of communication communities, the need for teachers to exchange experiences is necessary. Such associations are based on mutual learning and are organized as platforms for communication, offsite events, team competitions, mutual visits to classes, etc. Mixed communities have characteristics of both a problem-oriented and communication model. The article provides examples of Russian and foreign learning communities of teachers, which can be attributed to one of the models. In Russian practice, considerable experience has been accumulated in organizing communication learning communities at the level of cities, regions, and the whole country: all kinds of projects, festivals, competitions in which both beginners and experienced teachers can freely participate. According to the authors, in Russia they are more common than problem-oriented learning communities. Nevertheless, the latter may be of great practical interest for the teaching staff of separate schools.

Clinical Problems

Proper preparative procedures are a prerequisite for the validity of the results of x-ray microanalysis of biological tissue. Clinical applications of x-ray microanalysis are often concerned with diagnostic problems and the results may have profound practical significance for the patient. From this point of view it is especially important that specimen preparation for clinical applications is carried out correctly.Some clinical problems require very little tissue preparation. Hair, nails, and kidney and gallbladder stones may be examined and analyzed after carbon coating. High levels of zinc or copper in hair may be indicative of dermatological or systemic diseases. Nail clippings may be analyzed (as an alternative to the more conventional sweat test) to confirm a diagnosis of cystic fibrosis. X-ray microanalysis in combination with scanning electron microscopy has been shown to be the most reliable method for the identification of the components of kidney or gallbladder stones.A quantitatively very important clinical application of x-ray microanalysis is the identification and quantification of asbestos and other exogenous particles in lung.

Employees (N = 170) of a City Hall in Italy were administered a questionnaire measuring collective efficacy (CE), perceptions of context (PoC), and organizational commitment (OC). Two facets of collective efficacy were identified, namely group and organizational. Structural equation models revealed that perceptions of top management display a stronger relationship with organizational collective efficacy, whereas employees’ perceptions of their colleagues and their direct superior are related to collective efficacy at the group level. Group collective efficacy had a stronger relationship with affective organizational commitment than did organizational collective efficacy. The theoretical significance of this study is in showing that CE is two-dimensional rather than unidimensional. The practical significance of this finding is that the PoC model provides a framework that public sector managers can use to increase the efficacy of the organization as a whole as well as the individual groups that compose it.

SummaryTemperature represents a very important variable in ADP-induced platelet aggregation.When low doses of ADP ( < 1 (μM) are used to induce platelet aggregation, the length of the incubation period of PRP in the cuvette holder of the aggregometer, thermostatted at 37° C, is very critical. Samples of the same PRP previously kept at room temperature, were incubated for increasing periods of time in the cuvette of the aggregometer before adding ADP, and a significant decrease of aggregation, proportional to the length of incubation, was observed. Stirring of the PRP during the incubation period made these changes more evident.To measure the exact temperature of the PRP during incubation in the aggre- gometer, a thermocouple device was used. While the temperature of the cuvette holder was stable at 37° C, the PRP temperature itself increased exponentially, taking about ten minutes from the beginning of the incubation to reach the value of 37° C. The above results have a practical significance in the reproducibility of the platelet aggregation test in vitro and acquire particular value when the effect of inhibitors of ADP induced platelet aggregation is studied.Experiments carried out with three anti-aggregating agents (acetyl salicyclic acid, dipyridamole and metergoline) have shown that the incubation conditions which influence both the effect of the drugs on platelets and the ADP breakdown in plasma must be strictly controlled.

The article presents a structural description of the functioning of the regional information and communication system “Student and Labor” (SAL). This system is aimed at identifying and developing creatively gifted youth in the field of science, techniques and technology and is focused on the gradual involvement of university students in real work and interaction with leading enterprises in the region. The first cycle of the SAL system functioning is described, which has a complete character and has already led to a concrete result. The bank of information about the leading enterprises of the region that took part at the initial stage of the functioning of the SAL system were formed as well as the bank of 150 themes of scientific research for student projects, which were proposed by the enterprises themselves. All projects are focused on the practical significance of research for the enterprises themselves, as well as for students, their supervisors from universities and scientific consultants from enterprises that have embarked on joint research activities, which at the first stages are mostly of informational and educational nature. The Union of Employers of the Samara Region and the Council of Rectors of Universities in the Samara region are already taking the necessary measures to implement the described cycle of the functioning of the system SAL in the current academic year.

Machine fault detection has great practical significance. Compared with the detection method that requires external sensors, the detection of machine fault by sound signal does not need to destroy its structure. The current popular audio-based fault detection often needs a lot of learning data and complex learning process, and needs the support of known fault database. The fault detection method based on audio proposed in this paper only needs to ensure that the machine works normally in the first second. Through the correlation coefficient calculation, energy analysis, EMD and other methods to carry out time-frequency analysis of the subsequent collected sound signals, we can detect whether the machine has fault.
