The results of an empirical study of the working time consumed in strawberry production on Finnish farms are reviewed. Forty growers participated in the study, which took place between 1977—80. The purpose of the study was to determine how much time was consumed in working the fallow ground and during the summer of planting, in the first fruiting year and in the next four or five growth periods. Two cultivation methods were treated separately. The whole strawberry cultivation area was 95,1 ha. In the method in which the earth surrounding the bushes was covered with a black plastic film, the total consumption of working time was 409,0 h/ha using a one-row system and 572,5 h/ha using a double-row system during the fallow period and the summer of planting. During the first fruiting year the figure was 492,5 h/ha and in the next fruiting years 1 348,5 h/ha, including the time spent on harvesting. Where mulch was applied, the corresponding averages were 235,5 h/ha, 612,5 h/ha 1 182,0 h/ha. Factors affecting the variation in the total working time between farms were studied by linear regression analysis. Factors such as e.g. total strawberry cultivation area, the number of plants per hectare and the number of the years the grower had been cultivating strawberries, did not explain the variation in the working time satisfactorily. The yield per hectare, percentage of the different varieties cultivated, planting system, cultivation and picking methods explained only 33 % of the variation in labour output of picking.

Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.

Abstract: Plant vegetative development has been widely described using the phyllochron concept, but little effort has been made to describe flower development during the reproductive phase. The objective of this work was to present the anthochron, through a review of the literature, as a building block of flower development, mainly during the flower opening phase. The anthochron is the time interval needed for two subsequent flowers to achieve the same developmental stage, with units of time in days or in ºC day per flower. The concept of anthochron fulfills part of the lack of studies on flower development, since it is considered a building block of the flower opening process. The anthochron can be measured from field experiments or estimated by a simple linear regression analysis. So far, the anthochron has only been quantified in Gladiolus x grandiflorus Hort. Therefore, factors affecting the anthochron still need to be determined in order to pinpoint their effect on the flower opening rate.

Wetland Conversion

Conversion of agricultural land in urban areas is most prevalent in wetlands, thus threatening food availability and loss of multifunctional land. In the last five years, the wetland area in Bogor City has dropped dramatically to 321 ha (BPS of Bogor City, 2016). Control of the rate of conversion of wetland in Bogor City is regulated by Local Regulation number 8 year 2011 concerning Bogor City Spatial Plan (RTRW Kota Bogor) 2011-2031. However, its implementation is less effective so that there is a need for economic instruments to support it. The purpose of this study is to describe the wetland conversion in Bogor City and budgetary strategies in order to control it. Spatial analysis with overlay method was used to and resulted in a land conversion pattern which was dominated by housing area of 1 137.33 ha (47.08%) and garden 254.28 ha (10.53%). The conversion pattern was used as the basis of multiple linear regression analysis of factors affecting wetland area in Bogor City during 2000-2015 which results were: production amount (significant at α 1%); building area (significant at α 5 %); realization of Bogor City Agricultural Service budget (not significant) with R2 value = 86.6%. Wetland conversion control was conducted through budget strategies which are analyzed with Analitycal Hierrachy Process (AHP) calculation, resulting as follows: (1) socialization budget; (2) budget for formulating local regulation; (3)budget sharing with the central/provincial government; (4) streamlining the role of the private; (5) budget supervision; (6)budget for (land banking); (7) incentives and disincentives for farmers.

Main Factor

The development achievement of an economic activity can be measured by economic growth. Economic growth will improve if there are activities carried out by humans for the prosperity of the earth and their prosperity. An important factor for increasing economic growth is international trade, one of which is exports. Allah SWT has created in every region and country the advantages and disadvantages. The main factor that also has an influence on the economic development of a country / region is investment activities. Regarding investment in the Al Qur’an, it is clearly stated that investing is a way that is ordered by Allah SWT not to leave the weak generation. In this study, an analysis of the economic growth of the province of Jambi was conducted in 2012-2019. The method used is multiple linear regression analysis. Based on the results of using the R application, there is a significant influence between the export variable and the investment variable on the economic growth variable. The modeling results obtained are Y = 5848.0543 + 0.8886X1 + 0.7929X2. Every increase in exports of 1 billion and investment is considered constant, it will increase economic growth by 0.8886 billion. Every increase in investment of 1 billion and exports are considered constant, it will increase economic growth by 0.7929 billion. The coefficient of determination of 94.06 percent means that the diversity of economic growth variables can be explained by the export and the investment, the remaining 5.94% is explained by other variables not included in the regression model.

Slender Columns

The stability and strength of slender Reinforced Concrete (RC) columns depend directly on the flexural stiffness EI, which is a major parameter in strain calculations including those with bending and axial load. Due to the non-linearity of the stress-strain curve of concrete, the effective bending stiffness EI always remains variable. Numerical simulations were performed for square and L-shaped reinforced concrete sections of slender columns subjected to an eccentric axial force to estimate the variation of El resulting from the actual behavior of the column, based on the moment-curvature relationship. Seventy thousand (70000) hypothetical slender columns, each with a different combination of variables, were used to investigate the main variables that affect the EI of RC slender columns. Using linear regression analysis, a new simple and linear expression of EI was developed. Slenderness, axial load level, and concrete strength have been identified as the most important factors affecting effective stiffness. Finally, the comparison between the results of the new equation and the methods proposed by ACI-318 and Euro Code-2 was carried out in connection with the experimental results of the literature. A good agreement of the results was found.
