Some Statistical Properties of Models of Transitory Earnings

Miroslava Vlčková, Tomáš Buus

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 189-198 | DOI: 10.11118/actaun.2021.015  

The fact that most of the financial ratios are mean-reverting, is well known. Due to the importance of earnings forecast accuracy, relevant scientific literature in this area concentrates on transitory earnings. The main models used for description of earnings and/or profitability time series are adaptive expectation, autoregressive and partial adjustment models. However, their construction implies severe drawbacks like assumption of intentional adjustment of earnings, sometimes even towards unknown target or towards company-specific target uninfluenced by market, instead of rather realistic assumption of random push of market forces, as we found earlier....

Dimo Dimov, Ivaylo Marinov, Toncho Penev

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 199-202 | DOI: 10.11118/actaun.2021.016  

The survey was conducted in workers in dairy farming in Bulgaria. In the survey were not reported Thermal Work Limit (TWL) index values, which require cessation of employment and constitute a danger to human health. The lowest values of TWL were registered during the summer and spring months, respectively 229.3 and 258.4 W/m2. The highest are normally registered in the autumn and winter months - 318.3 and 312.2 W/m2. Outdoor the lowest average TWL values were reported in the summer and spring months 236 and 287.9 W/m2, respectively, and the highest in the autumn and winter months - 316.4 and 317.2 W/m2. An...

The impact of different levels and sources of coppermixedligand on productivity and its metabolism in young rabbits of California breed in combination with sulfates was investigated in experiment. For rabbits of the 1st control group 7.81 g/t of copper sulfate was injected into the mixed fodder, of the 2nd experimental group - 7.81 g/t of coppermixedligand, of the 3rd, 4th and 5th experimental groups, respectively, g/t: 5.86; 3.91 and 1.95. As a result, the rabbits of the 1st control group and the 2nd experimental group deficit of copper was eliminated by 100% to the existing...

Jiří Boháček, Zdeněk Linhart, Peter Matisko, Miroslav Špaček

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 211-220 | DOI: 10.11118/actaun.2021.018  

CSR actions are often controversial due to either the excessive voluntary or narrow standardized approach. The objective of this article is to find indices, which homogenize CSR campaigns of corporations according to specific attitudes and behaviour of individuals. Cluster analysis has significantly differentiated CSR volunteering contributors from non-volunteering critics. A small cluster of non-volunteering respondents calls for support of kids, criminals and addicts. Volunteering clusters are composed of employed respondents who are predominantly calling for equality and environment according to their work and leisure interest. The technology volunteering...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 231-239 | DOI: 10.11118/actaun.2021.020  

The weakness of most farmer-groups in Nigeria has been linked to poor group facilitation by field agricultural extension workers. The study assessed the knowledge and competence of extension officers in group facilitation. A two-stage random sampling technique was used to select 174 farmers on which a structured interview schedule was administered. A questionnaire was administered on all 69 field extension workers in the study area. Descriptive statistics, regression analysis, Pearson's Product Moment Correlation and t-test were used for data analyses. Results reveal that 65.2% of extension workers had good knowledge of group facilitation. Farmers...

A multistage random sampling technique was used to sample two hundred and fifty five (255) respondents. Data were collected through a structured questionnaire and were analyzed using descriptive and inferential statistical tools. Results revealed that mean age of respondents was 36.9 years and that majority (53.7%) of the respondents were male. The hierarchical regression analyses results indicated that overall job performance was significantly related to political deviance (b1 = -2.015, p < 0.05),...

Consumer Ethnocentrism: Comparison of Slovakia and the Czech Republic

Marián Čvirik

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 259-266 | DOI: 10.11118/actaun.2021.023  

Consumer ethnocentrism is an important concept that few scientists are researching in the context of comparing two countries. The main aim of the article is to examine the level of consumer ethnocentrism and its differences in selected countries - Slovakia and Czech. The measurement was performed on the basis of the CETSCALE instrument. We verified the reliability of the instrument on the basis of Cronbach's alpha, while high reliability can be stated. The results suggest that Czechs are more consumer ethnocentric than Slovaks (about 9%). The one-way ANOVA test was used to explore the impact of selected demographic factors (age and gender) on consumer...

Tri Atmowidi, Sih Kahono, Dorly, Suci Dwi Rahmawati, Delbert Reinaldo, Eris Safiril Ummah

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 267-273 | DOI: 10.11118/actaun.2021.024  

Salacca (Salacca spp.) is a dioecious plant with male and female flowers existing on a different plant, therefore requires agents of pollination. More than thirty cultivars of salacca are found in Indonesia. This research aimed to study the diversity of visiting insects on the three varieties of salacca, i.e., Pondoh, Mawar and Kalimantan in Indonesia, as well measuring the pollen load on the pollinators. The visiting insects were observed on the male flowers using the fix sample method in ten minutes for fifteen days. Results showed that nine insect species visited the flowers and three species were potential pollinators, i.e., Nodocnemis sp., Apis...

The "Normatives" Controlling Approach in SMEs in Bavaria

Stefan Ehrnböck, Pavel Žufan

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 275-279 | DOI: 10.11118/actaun.2021.025  

This paper analyzes the effectiveness and efficiency of the normatives' controlling against the operational and strategic controlling. The general focus in studies and focus of the controlling experts is mostly on the operational controlling. For the analysis of the normatives' controlling in Bavarian SMEs a primary research data set is used. The survey was aimed on Bavarian SME's in the machine building sector. We employ regression models for the assessment of significance of the influencing factors, which are causing the negation of the normatives' controlling. We use monthly hours worked in the normatives' controlling, percentage acceptance of the...

Since 2015, the Federal Republic of Germany has accepted more than one million refugees. In many cases, the refugee crisis in Germany is seen as an opportunity to compensate for the need for skilled labour. By 2030 there will be a shortage of around 3 million skilled workers. Therefore, this article focuses on the educational structure of refugees in the years 2015-2017. A survey of a total of 687 refugees and a comparative analysis using data from the Federal Office for Migration and Refugees (BAMF) revealed that about 70% of asylum seekers are of working age. 14% of the refugees have no formal education. More than 50% have attended primary and secondary...

Dominika Mikusova, Pavel Ryant

Acta Univ. Agric. Silvic. Mendelianae Brun. 2021, 69(2), 291-298 | DOI: 10.11118/actaun.2021.028  

The aim of this study was to evaluate the effects of added nitrification inhibitor (NI) and urease inhibitor (UI) to urea ammonium nitrate (UAN) on oilseed rape yield and seed oil content in 3-year field trials and to assess their environmental impact by analysing the content of nitrates in water extracts in the form of soil laboratory experiments. The UAN stabilisation was provided by the addition of PIADIN (1.5% methylpyrazole, 3% triazole) serving as NI and StabilureN (NBPT) used as UI. The experiment consisted of four variants: 1. UAN; 2. UAN + NI; 3. UAN + UI; 4. UAN + NI + UI. The obtained data showed the increased rates of the yield and seed...
