The aim of the study was to evaluate cocoa beans quality produced in Cameroon, Ecuador, Nigeria and Ghana from safety position determining heavy and trace metals concentration and evaluating the oxidative stability of confectionery products prototypes (trials) with analysing cocoa beans. For evaluation of oxidative stability of confectionery products, the main ingredients - butter and cocoa beans kernels were tested making trials as milk chocolate prototype. The composition of confectionery ingredients affects quality of products; therefore it is very important to evaluate quality of raw materials in confectionery industry, as they are purchased practically in all regions of the world. Mercury, arsenic, lead, cadmium concentration was determined in whole cocoa beans as their presence in foods have toxic effect on human beings and their concentration are strictly limited as maximum residue limits for processing. Cocoa shells can be used as additive to confectionery products recipes therefore the object of the study was cocoa beans and cocoa shells. Analyzing cocoa beans quality indices there was established that lead, cadmium, aluminium and zinc concentrations vary in cocoa beans significantly. Differences in lead concentration in cocoa beans from Ghana, Cameroon and Ecuador were significant (p < 0.05) compared with concentration of lead in cocoa beans from Nigeria (p > 0.05). Cadmium concentration in cocoa beans from Cameroon was significantly different comparing with cocoa beans from Nigeria, Ecuador and Ghana (p > 0.05). Differences in aluminium concentration in cocoa beans kernels were significant (p < 0.05) in all analyzed samples. Concentration of zinc was higher in shells of cocoa beans, especially in shells of cocoa beans from Ecuador (p < 0.05). The presence of cocoa products in milk chocolate prototypes inhibited the speed of lipid peroxidation. The different trace and heavy metals concentrations in cocoa beans should be taken into account choosing ingredients and components for confectionary products production particularly those with high content of cocoa (chocolates, sweets, cocoa fillings, cocoa creams and others) with the aim to prevent oxidation process during shelf-life of products.

Analysing cocoa beans quality indices there was established that lead, cadmium, aluminium and zinc concentrations vary in cocoa beans significantly. Differences in lead concentration in cocoa beans from Ghana, Cameroon and Ecuador were significant (p is less than 0.05) compared with concentration of lead in cocoa beans from Nigeria (p is greater than 0.05).

The employment of people with disabilities has multidimensional aspects - economic, social, legal, human rights, discrimination, psychological, ethical and responsibility aspects - with different actors involved representing various kinds of interests. The European Union Disability Action Plan and Strategy specifies the objective of promoting the employment of people with disabilities in the open labour market. The employment of such individuals is not only an economic issue, but also an issue of social inclusion, poverty reduction, equal opportunity and socially responsible employment. Effective and fair use of human resources for national economic development requires a variety of support mechanisms, including regulatory frameworks, the active involvement of local municipalities, and measures taken by state institutions. Because of the different issues and the various actors with different interests involved, an integrated way has to be considered to analyse the employment factors and employment opportunities for people with disabilities. The purpose of this study is to explore and substantiate the possible scenarios associated with promotion employment opportunities for people with disabilities in Latvia. The research methodology employed for this study is based on the Analytic Hierarchy Process, and expert interviews are used to analyse the interests of all involved parties, in order to determine the best possible scenarios as to how to stimulate employment for people with disabilities. As a result, three scenarios to promote the employment of people with disabilities were developed. Although the results showed slight differences between the three scenarios, experts believe that the optimal scenario for promoting the employment of people with disabilities is the one in which the EU participates.

Information and communication technologies are part of almost any branch of human lives. During the last decade also beekeeping joined the direction of application of IT tools and solutions and precision beekeeping was defined. Still in the beekeeping many operations and observations are completed manually, and there is a potential to switch to the digital realisation. Information technologies can be used in the beekeeping to partly support the beekeepers by implementation of automatic or semi-automatic solutions for bee colony remote monitoring, apiary record making and other actions. The aim of this paper is to make a summary of the usage of information technology tools by the beekeepers in Latvia, summarizing precision beekeeping development status and conclude about its future development potential. To achieve this aim, in cooperation with Latvian Beekeepers Association, a beekeepers survey was conducted. More than 200 beekeepers shared thoughts and opinions about their application of information and communication technologies for monitoring the bee colonies and apiary management. The summary of the survey conducted is described in this study.
