Music schools in Latvia provide pupils with musical education both in the towns and rural areas of Latvia. Studies include instrumental playing, history of music, and music theory lessons. An actual pedagogical problem at the time is activation of pupils' learning. Self-regulated learning acquires significant meaning for pupils' future life. A way of helping pupils' self-regulation in learning is differentiation of learning methods and forms. The aim of the paper is to research the meaning of music schools' ensemble work (collective performance) for enhancing pupils' self-regulated learning. Learning is a process where an individual inherits accumulated experience of the society acquires skills, knowledge, attitudes, enhances his experience, individually and responsibly working and discovering himself, nature and society. Learning as an activity is based on learning experience. According to L.S. Vygotsky's theory of learning, the cultural development depends upon social interaction. The use of ensemble work (collective performance) in school as a form of learning activity and method observes a reciprocal movement towards didactic goal, includes the components of due learning contents (knowledge, skills, instrumental playing experience, attitudes), the results of learning process and its evaluation. Analysis of the obtained data shows that music teachers choose ensemble work as method and form of teaching to indirectly influence the self-regulated learning of pupils, whereas the pupils do not fully understand the significance of ensemble work for enhancing self-regulated learning techniques.

Deep learning algorithms are becoming default solution for application in business processes where recognition, identification and automated learning are involved. For human identification, analysis of various features can be applied. Face feature analysis is most popular method for identification of person in various stages of life, including children and infants. The aim of this research was to propose deep learning solution for long-term identification of children in educational institutions. Previously proposed conceptual model for long-term re-identification was enhanced. The enhancements include processing of unexpected persons’ scenarios, knowledge base improvements based on results of supervised and unsupervised learning, implementation of video surveillance zones within educational institutions and object tracking results’ data chaining between multiple logical processes. Object tracking results are the solution we found for long-term identification realization.

The variety of study methods used at universities still is conservative and more pragmatic, but there is an increasing tendency to change study methodology to more and more student-centred and to focus on the students’ ability to become valuable workforce for SMEs. The necessity for development of study methods clearly demonstrates the research problem. At the same time, universities are facing pressure from governmental authorities to internationalize – student and teacher mobility, international partners and projects are highly recommended. The main process at universities is the study process. But also internationalization should support the study process and students in achieving practice-based learning outcomes. Facing these challenges, NOBANET network of universities has elaborated and piloted the study method Cross-Border Assignments (CBA) linking students’ future ability to successfully incorporate in the job market and the requirement for internationalization of studies. The aim of this article is to introduce and assess the CBA as a method to involve student work and students to engage in entrepreneurship problems. The authors have collected and analysed feedback of 10 CBAs implemented in 6 different universities. The feedback was received by using questionnaires with mainly closed questions. The results show that companies are satisfied with students’ work and they also appreciate teachers. The main conclusion about assessment of this method gives valuable contribution to scientific literature as a description of modern study method and good practice in linking HEIs and SMEs. Gratitude is expressed to the Nordic Council of Ministers for funding NOBANET project and project EKOSOC-LV, part 5.2.2. and INTERFRAME-LV.

The aim of the study is using systematic literature analysis method – literature overview – identify the factors, which affect the competitiveness of a higher education institution in the conditions of globalization. Qualitative methods, as well as systematic literature analysis method – literature overview have been used in the study. More than 6000 scientific articles were considered to choose 20 full text articles for in-depth analysis. Main conclusions and results – the systematic literature analysis method – literature overview is a convenient tool for systematizing, selecting and collecting information about the research subject, using author’s articles, which have already gathered key information from a number of researchers of a specific topic together; the competitiveness of higher education institution is influenced by the internal factors that are formed by the internal environment of the higher education institution and external factors that are formed by the external micro-environment and macro-environment influenced by the state policy; an analysis of the internal and external factors of an institution is important in order to create competitive advantages in a higher education institution.

Company - oriented risk analyses is the necessary precondition to establish, validate and improve HACCP procedures in catering enterprise. In catering area no microbiological criteria exist for ready-to eat food in both European and Latvian level. The objective of the study was to apply risk assessment approach to evaluate microbiological risks during food preparation processes in school catering establishments. The aim of the author's research was to assess the level of microbiological contamination of food as well as the changes of microbial contamination during technological processing of food to motivate the necessity for controlling of food contamination levels in frame of HACCP procedures. It was concluded that no significant risk in consumption of cooked minced meat food if cooking temperature is adequate and food is stored at correct temperature after cooking. The storage of salads in ambient air temperature causes a significant increase of bacterial contamination due to high initial contamination level that may create a serious risk in case of pathogenic bacteria. On the basis of research it was concluded that microbiological investigation should be a recommended way to test step-by step the performance of technological processes because the hygiene situation is specific to each catering establishment and safety of the end-products may vary considerably. Microbiological testing of food and environmental samples could be a helpful tool for development and validation of HACCP procedures to assess potential risks and to establish critical limits for managing of technological steps in school food service area.

In XX century, educational dialogue is researched as educational and pedagogical method. The rural music schools of Latvia are good basis for scientific investigation. The aim of the research is to study situation of the educational dialogue in Latvia rural music schools and to analyse pedagogical aspects and authority, constructing progressive environment in understanding between individuals. A two thousand year's dialogue shows perspective way for best communication and cooperation. Dialogue idea in XX century philosophical and pedagogical theories is analysed in M. Bbuber, M.M. Bakhtin, P. Freire and N.C. Burbules works, and they have played an important role in the development of dialogue theory as a pedagogical problem. Dialogical interaction can provide to higher motivation of ensemble play lessons and to solve transportation and large way distance difficulties in Latvia rural areas.

The aim of the research was to find out different aspects of food environment at schools, linking them to the economic situation in the regions and comparing those to the tendencies in Riga. The research shows that there is a need for common politics concerning school meals as every schools follows its own practice that mainly depends on social budget of the local government institutions, qualifications of scool personnel and different eating traditions in different regions.
