A Cloud point extraction (CPE) procedure was presented for preconcentration of lead(II) ions, after complexation by 18-crown-6 (18C6) and extraction with Triton X-100 at proposed experimental conditions. After separation of surfactant - rich phase, content of Pb(II) ions in remaining solution was measured by Flame Atomic Absorption Spectrometry (FAAS). The experimental conditions such as pH, temperature, concentration of Triton X-100, concentration of 18C6, incubation time, type and concentration of added electrolyte, were evaluated. Results showed that among investigated electrolytes (NaCl, Na2SO4 and Na2CO3) the amount of 0.9 mol/L Na2CO3 lowers cloud point temperature of Triton X-100 to 22?C (room temperature during the experiment), thus simplifying the extraction procedure. After an incubation time of 5 minutes and using the concentration of 1.2?10-3 mol/L Triton X-100 and 1.5?10-4 mol/L 18C6 (1:1 stoichiometric ratio for 18C6:Pb), 60% of lead (II) ions were efficiently removed from investigated solution.

The beginning of the 21st century in the Federation of Bosnia and Herzegovina (henceforth referred to as ?the Federation?) has been characterised by a decrease in the primary-school-age population. As such, the main objective of this work is to define and explain the factors that have influenced the decrease in the primary-school-age population in this part of Bosnia and Herzegovina. The research methodology applied in this work is oriented towards defining the degree of influence of demographic factors on the development of the primary-school-age population in the Federation. By using statistical methods and GIS analysis of statistical data, negative demographic trends were confirmed in the Federation at the end of the 20th and the beginning of the 21st century. These trends included intensive migration, a decrease in the total number of inhabitants, a decrease in the birth rate, an increased mortality rate, a decreased rate of natural population change, and the ageing of the population. Due to adverse economic, social, political, and other circumstances after 1995, population emigration has been intensified, most noticeably within the population aged between 20 and 40. The most important result of the research is the fact that the decrease in the natural population dynamics and intensive emigration are the most significant factors influencing the decrease in the primary-school-age population in the Federation. Such negative demographic trends influence the primary education system adversely. In the future, it will be necessary to plan and implement a population-revitalisation process as part of the federation?s overall population policy.

. Talent management is considered to be one of the most popular management topics, both in theory and in practice. The term "talent" dates back to ancient times, while the term "talent management" was first mentioned in 1998, when a group of McKinsey consultants published a study titled "The War for Talent", which highlighted the positive impact of talent on organizational excellence. Both talent and talent management can be defined in numerous ways. Simply stated, talents represent the "right people", which refers to individuals who have key competencies a company needs, while talent management can be defined as getting the right people in the right roles at the right time. According to the survey conducted in Bosnia and Herzegovina, the terms "talent" and "talent management" are familiar to most respondents. Additionally, most respondents believe that talent management improves employee motivation and performance, as well as the performance of the entire enterprise. The research also showed that in most Bosnian companies, talent management practices are not implemented, and this applies to special programs for talented employees as well. The majority of survey respondents also expressed that they would appreciate working in talent focused organizations.
