Abstract

Introduction of work-based learning (WBL) in Latvia has required new approaches in decision making of different stakeholders. Experience from countries with long-standing WBL tradition has shown the numerous advantages but also the challenges this approach presents. One of these challenges is the need for new forms and mechanisms of cooperation among the key stakeholders – policy makers, public administrators, employers, educators and social partners. The current paper analyses the results of scientific research in this field, as well as uses the empirical results of two surveys performed by the authors: a survey of public sector experts and a survey of employers in Latvia. In order to obtain detailed results, the evaluations of respondents on multiple aspects analysed in the surveys were evaluation in the scale 1–10. The data of both surveys have been analysed by descriptive analysis, cross-tabulations and multivariate analysis – factor analysis. The results have indicated that the views of employers and social partners on the most of the key aspects of introduction and implementation of WBL are similar. However, a more profound analysis has to be performed in order to develop proposals or the most efficient approach to WBL.

Abstract

By developing new varieties suitable for the production of healthy products, given the greater consumer and manufacturer focus on the functional ingredients and nutritional properties of barley, new opportunities to incorporate barley into human foods are created. Therefore, the aim of investigation was to analyze grain composition of barley varieties and perspective breeding lines bred in Latvia and to evaluate its functional ingredients depending on varieties, year and nitrogen fertilizer rates. The content of protein, starch, β-glucans, total dietary fiber, composition of amino acids and α-tocopherol were determined in the studied samples. The results of two-year analysis showed that the protein content in barley grain samples ranged from 10.5 to 13.9%, total dietary fiber – from 18.74 to 20.82%, but the content of β-glucans ranged from 3.44 to 4.97%. The content of α-tocopherol was determined to range from 7.21 to 8.58 mg/kg, and the sum of essential amino acids – from 31.5 to 38.9 g/kg. Although covered barley varieties demonstrated a higher content of such functional ingredients as α-tocopherol, total dietary fiber and β-glucans, naked barley grains had a higher protein content, the sum of essential amino acids, and, particularly lysine, was not far behind the content recommended by nutrition experts.

Abstract

The aim of the study was to determine concentrations of 13 macro and trace elements in different barley genotypes depending on the year of growth (2011, 2012, and 2013) and agricultural practice (conventional/organic). Cd, Pb, Cr, Ni, and Al concentrations were determined by electrothermal atomic absorption spectrometry and K, Na, Zn, Cu, Ca, Mg, Mn, and Fe concentrations by flame atomic absorption spectrometry. Statistically different concentrations of Cr, Cu, and Zn occurred among genotypes; for Ca, Mn, and Fe concentrations between barley grains, grown conventionally and organically; for Cr and Ni concentrations between hulled and hull-less grain and for Cd, Cr, Ni, Cu, Zn, Al, K, and Na concentrations among the study years. Concentrations of potentially hazardous elements were low (Cd < 0.005–0.027, Pb 0.013–0.066, Cr 0.111–0.327, Ni 0.161–1.264, Cu 2.8–4.7 and Al 1.62–6.09 mg·kg−1). Barley products can provide necessary macro and trace elements, especially of Mn, Mg, Fe, and Zn (7.8–16.1; 1024–1249; 29.2–52.9, and 20.5–33.7 mg·kg−1, respectively).

Abstract

Cereal-based foods have great importance in the compensation of micro- and trace element deficiency, because 50% of the foods produced worldwide are made up of cereal grains. The aim of the research was to determine the concentration of macro-elements and trace elements in different cereals cultivated in Latvia. Various cereals were used in the research: rye (n = 45), barley (n = 54), spring wheat (n = 27), winter wheat (n = 53), triticale (n = 45) and oats (n = 42). Thirteen macro- and trace elements (Cd, Pb, Ni, Cr, Al, Cu, K, Na, Mn, Fe, Zn, Mg, Ca) were determined in cereal grain samples (n = 266). Macro-elements and trace elements varied significantly (p < 0.01 or p < 0.001). The highest concentrations of macro- and trace elements were found in oats and the lowest in rye. The obtained data will expand the opportunity for food and nutrition scientists to evaluate content of the examined elements in grain products, and dietary consumption (bioavailability) of the examined macro-elements and trace elements.

Abstract

Qualified, loyal and motivated employees are highly demanded by employers and business promoters. The paper deals with employers’ needs and expectations for qualified and loyal employees, and investigates cooperation of employers, educators and municipalities. The following methods were used: analysis of scientific publications; focus group discussions; surveys of employers, teaching staff, students and graduates of VEI. For survey data analysis descriptive statistical analysis, non-parametric statistical test of Kruskal-Wallis and factor analysis were applied. The main findings indicate that besides professional skills and competence, social competence, motivation to work and responsibility are requested as well.
