Even though thousands of people suffer from hunger each day, there are people that simply throw away their food, imposing serious environmental, social and economic consequences. Food waste concept, however, is not as strictly defined as it varies from research to research. The classification itself can be specific to certain regions and cultures, and it can even be affected by the eating habits of the researchers. This review paper aims to unify the theoretical knowledge of food wasting with examples from actual research, evaluating data from the perspective of eating habits and finding motives for such an action, such as family and friends’ influence, incomes, lifestyle, religion, mass media etc. Previously done studies show that people are less concerned about reducing food wastage when it comes to environmental and social problems, but are the most motivated if they see a real opportunity to save money.

The concept of polycentric development at multinational, national and regional level is broadly used in academic research of regional development and spatial planning. It is also reflected in the normative agenda by the European Union. However, polycentricity has been considered a fuzzy concept, and it still lacks commonly accepted definition or measurement methods. Albeit a plethora of researchers and policy makers favours polycentric development as a tool for reduction of regional disparities, these statements are not based on empirical foundations. The research objectives are twofold and consecutive. The first objective is to define the morphological measures of polycentricity and apply these measures at country level. The second objective is to empirically test the following hypotheses: regional disparities in countries with polycentric urban system are less pronounced than in countries with monocentric urban system; income distribution in countries with polycentric urban system is more equal than in countries with monocentric urban system. The hypotheses stated by the objective of the study can be rejected: regional disparities in countries with polycentric urban system are not less pronounced than in countries with monocentric urban system; income distribution in countries with polycentric urban system is not more equal than in countries with monocentric urban system. The research results clearly suggest the polycentric development cannot be considered a tool for diminishing regional disparities and providing more cohesion between regions.

Social entrepreneurship plays an increasingly important role in tackling socio-economic problems. It has gained recognition in Latvia among politicians, academicians and social entrepreneurs; consequently, the number of social enterprises increased in the country, yet there is a lack of research studies on social enterprise models and their classification. Accordingly, the research aim is to examine the theoretical models of social enterprises in Latvia. In the scientific literature, there is no strict classification of social enterprises, but based on different criteria, it is possible to distinguish several types or models. In Latvia, there are relatively few social enterprises; for this reason, it is quite difficult to categorise them. However, social enterprises are divided by sector, field of activity, target group, scale of activity and other criteria. The research stresses the following key social entrepreneurship models: the Selfinitiative Model, the Government Participation Model, the Municipal Participation Model and the Company-initiated Development Model. These models are based on two key criteria – support intensity and taking the initiative in establishing and developing a social enterprise.

This paper summarizes the results of a theoretical study as well as practically oriented research about the concept of managing the social sphere of the village and considers the problem-perspective field of development the social infrastructure management in the villages of the Republic of Kazakhstan. The chosen topic is relevant as an insufficiently studied scientific problem, and also has practical significance for the well-being and stable development of rural areas. The study describes the scheme of management of the rural social infrastructure in the Republic of Kazakhstan from the standpoint of object-subject, methods and results. Interviews of the rural population were conducted about the satisfaction with the rural social infrastructure and attitude towards the work of local governance. Rural settlements of Mangystau oblast currently have an average not significant level of social infrastructure development and the level of satisfaction of residents in different areas with its condition varies from very low to sufficient. The most important principles for the development of definition of rural social infrastructure management and its functions have been highlighted with the help of a comparative analysis of various approaches. According to the results of the study, it was concluded that the development of promising directions of management the rural social infrastructure requires a comprehensive study and evaluation of the facilities, mechanism and principles of this management and the identification of its current problems with regional development tasks.
