Students Attitudes

The aim of the research presented in the paper is the empirical study of the semantic attitudes and life meanings of students in the perception of advertising posters. Advertising impact is viewed as a process of broadcasting the meanings concentrated in advertising posters. The study sample consisted of 80 students from two universities (Rostov-on-Don, Russia). To determine the severity of life meanings, the method of life meanings was used by V.Yu. Kotlyakov (V.Yu. Kotlyakov, 2003), the method of expert assessments was used to study advertising posters. The results were processed using the methods of mathematical statistics: descriptive statistics were used; as well as nonparametric tests for comparing several independent samples, the Kruskal-Wallis H-test, for studying the relationships between the scales of V.Yu. Kotlyakov and the assessment of advertising posters by the respondents used the Spearmans rank correlation coefficient. It was shown that in the process of broadcasting meanings in advertising posters, students semantic attitudes are actualized. The sample of students showed a tendency to evaluate advertising posters in accordance with the dominant meanings of life. It is shown that there is a relationship between the dominant life meanings of students and the ratings of advertising posters.

The aim of the study presented in the article is an empirical study of semantic attitudes and life meanings of students in the perception of advertising posters. Advertising influence is considered as a process of translation of meanings concentrated in advertising posters. The study sample consisted of 60 students from two universities (Rostov-on-don, Russia). To determine the expression of vital meanings we used the technique of life values Kotlyakov, V. Y. (Y. V. Kotlyakov, 2003), to studies of advertising posters we applied the method of expert evaluations. The results were processed by methods of mathematical statistics: descriptive statistics; nonparametric Kruskal-Wallis H-test for comparison of several independent samples, Spearman rank correlation coefficient. It was shown that in the process of translation of meanings in advertising posters there is an actualization of semantic installations of students. In a sample of students we recorded a tendency to evaluate advertising posters in accordance with the dominant meanings of life. It is shown that there is a relationship between the dominant life meanings of students and their estimates of advertising posters.

Caricature-plant cultivation is often damaged due to the attack of Doleschallia bisaltide larvae. High reproduction ability of D. bisaltide is a serious problem that need to be managed, therefore it will not inflict a financial losses. This study was aimed to determine the fluctuation of D. bisaltide larval population in the caricature-plant plantation in Kalisoro, Tawangmangu. The observations were carried out with a survey method on five observation plots for seven months from March to September 2018. The data were analyzed by descriptive statistics and the Spearman rank correlation coefficient test. The results showed that the population structure was changed during the observations with the highest larval population in May. The results of Spearman rank correlation coefficient test showed significant and positive correlation between third, fourth, and fifth instars larvae with the rainfall. The control of D. bisaltide can not only depend on the presence of natural enemies, therefore control interventions were needed especially at a suitable time and environment whne the population increased.

Displays and causes of laziness and procrastination vary in both their essence and the influence they have on human activity. Students with different academic performance tend to display laziness and procrastination in different ways. The results of the research on procrastination and laziness patterns, shown by students with various academic performance rates, are described in the article. The levels and causes of laziness and procrastination for students with different academic performance were defined by means of diagnostic methodology. Based on the methods of Mathematical Statistics, such as the Spearman's rank correlation coefficient and the Mann–Whitney U test, the levels of procrastination and laziness were compared in correspondence with students’ academic performance rates. A negative correlation was discovered between the level of academic procrastination and students’ academic performance. Another correlation was established for such causes of laziness as “Capability deficiency” and “Lack of interest”. The differences in laziness levels as well as causes of laziness and procrastination were identified between students with high and low academic performance rates. A conclusion was made that in the process of forming the basic conditions for studying, it is highly important to recognize displays of procrastination and laziness among students with different academic performance rates.

A group approach having an excess because its scope broader, and in accordance with communal culture of the people. Group dynamics and independency farmers become a yardstick to judge whether the programs the government (the course of development) involving group cattle farmers cut is sustainable or not, so that it can be evaluated for sustainability the next. The purpose of research are (1) analyze group dynamics formed in the group spr mega jaya, (2) analyzed levels of independency of farmers in the farmers spr mega jaya, (3) analyze relations group dynamics and independency of farmers with the success kejar farmers spr mega jaya. Data analysis of analysis descriptive statistics (a frequency, the percentage, on the average), and statistic analysis inferential by test a correlation coefficient rank the spearman. The research results show that group dynamics spr mega jaya tends in category high, and independency of farmers spr mega jaya tends in category enough, while test relations shows that there is a positive connection welfare between group dynamics the cattle farmer and independency of farmers with the success kejar cattle farmers cut. This means that the more dynamic group spr mega jaya and independency of felt farmers high, so the success of the program group farmers who reached the higher.Keywords: group dynamics, independency of groups, sekolah peternakan rakyatABSTRAKPendekatan kelompok memiliki kelebihan karena cakupannya yang lebih luas, dan sesuai dengan budaya masyarakat komunal. Dinamika kelompok dan keberdayaan peternak menjadi tolok ukur untuk menilai apakah program pemerintah (program pembangunan) yang melibatkan kelompok peternak sapi potong bersifat sustainable atau tidak, sehingga dapat dievaluasi untuk keberlanjutan program selanjutnya. Tujuan dari penelitian adalah (1) menganalisis dinamika kelompok yang terbentuk dalam kelompok SPR Mega Jaya, (2) menganalisis tingkat keberdayaan peternak pada kelompok peternak SPR Mega Jaya, (3) menganalisis hubungan dinamika kelompok dan keberdayaan peternak dengan keberhasilan program kelompok peternak SPR Mega Jaya. Analisis data berupa analisis statistik deskriptif (frekuensi, persentase, rata-rata), dan analisis statistik inferensial dengan uji koefisien korelasi rank Spearman. Hasil penelitian menunjukkan bahwa dinamika kelompok SPR Mega Jaya cenderung pada kategori tinggi, dan keberdayaan peternak SPR Mega Jaya cenderung pada kategori cukup, sedangkan uji hubungan menunjukkan bahwa terdapat hubungan positif signifikan antara dinamika kelompok peternak dan keberdayaan peternak dengan keberhasilan program kelompok peternak sapi potong. Hal ini berarti bahwa semakin dinamis kelompok SPR Mega Jaya dan keberdayaan yang dirasakan peternak tinggi, maka keberhasilan program kelompok peternak yang tercapai semakin tinggi.Kata kunci: dinamika kelompok, keberdayaan kelompok, sekolah peternakan rakyat

Necessary Existence

In this paper, we use the weak separability criterion to check for the existence of six different monetary aggregates reported by the Center of Financial Stability (CFS). We implement an extended version of the semi-nonparametric tests introduced by Barnett and de Peretti on US monthly data from January 1967 to December 2012. The test, first, checks for the necessary existence conditions of an overall utility function and a monetary subutility function, and then tests for the separability of the latter. On different subsamples, our results suggest that only the DM1 aggregate meets the separability criterion. Implemented on macroeconomic data, we have tested a joint assumption about separability and the existence of a representative agent. Thus, the rejection of the null could also be due to the rejection of stringent Gorman's conditions. More advanced tests for weak separability are clearly required to confirm the results found in this paper.
