Abstract:

Purpose The emergence of mega-farms in middle-income countries like Brazil and Ukraine and the efforts to consolidate small farms into larger ones in China and elsewhere have suggested that new institutional arrangements and technology progress may increase the significant farm economies of size, and therefore challenging the classical inverse relationship (IR) between productivity and farm size. The purpose of this paper is to conduct a research to examine the existence of IR in China’s cereal production and further explore the possible mechanism. Design/methodology/approach Based on the panel data concerning farms from 31 provinces in China in 2009–2014, technology efficiency and allocation efficiency in cereal production were measured based on the Translog production function. Findings In China, an IR exists between wheat, rice and maize production after controlling the related variables. Further, the presence of this IR is due to allocation efficiency rather than technology efficiency. Results of technology efficiency show that there is no significant difference between different size groups; in other words, even the larger size groups enjoy a higher technology efficiency in rice production. Results of allocation efficiency demonstrate that, compared with the larger farms, smaller holders tend to invest more in factors which are beneficial in growing productivity. Hence, yields of small-size farms exceed those of large-size farms, which consequently leads to the IR. Practical implications The scale consolidation of cropland is harmless to the efficiency of factor utilization and, conversely, may contribute in improving the technology efficiency of specific crops (like rice). Based on the results of allocation efficiency estimation, the extent of misallocation in large scales is relatively less due to their less input of fertilizer and pesticide; thus, the size-improving policy of farmland may contribute to the ease of the non-point pollution in agriculture. Originality/value The existing discussions of the IR in the context of recent China mainly focus on the accurate verification of IRs. This paper steps forward from the perspective of technology efficiency and allocation efficiency and explores the exact resources of IR with up-to-date and representative data and hopes to find some new conclusions.

Abstract:

Improving the energy-efficiency of computing systems has been the focus of computer science research for many decades. In the data center domain, for example, there has been an intense focus on improving energy efficiency by improving the Power Usage Effectiveness (PUE) of data centers. Other domains such as civil and mechanical engineering have also focused on improving the energy efficiency of built environments such as buildings. More recently, there has been an increased emphasis on sustainability on the human-built infrastructure of various kinds motivated by climate change, which has resulted in an emphasis on reducing carbon emissions of such infrastructure by optimizing their carbon efficiency.

Abstract:

Optimization of the energy consumption of a Dorna 1 commercial robot was carried out by replacing the original materials of the links (aluminum) with a lighter and more resistant material (carbon fiber) with the aim of lowering the operating costs of the robot. For this reason, a reduction in the total mass of the robot of 11.08% was achieved by replacing the original materials. In addition, simulations were carried out using finite element analysis to verify that the mechanical resistance of the optimized parts was adequate according to the level of demand that occurs during the operation of the robot. Subsequently, a comparison of the energy consumption of the original robot and the robot with the optimized parts was carried out using the Internet-of-Things device. The tests were carried out at three different speeds—1000, 3000, and 9000 deg/min—for 15 min by executing a pre-established routine starting from home. The results showed that at all test speeds, there were energy savings, but the greatest energy savings occurred at the speed of 3000 degrees/min in the range of 3.66%. With this result, it has been shown that the integration of light materials in robots can achieve energy savings.

Abstract:

Consumerism is on the list of critical targets of ecological economists, but an economic theory of consumerism has still to be developed. The present paper intends to contribute to such a theory based on an institutionalist view of consumption as a social process and focussing on the interrelations between consumers as skilled social agents, infrastructures and institutions. In the present paper consumption is understood as the life-process encompassing all kinds of social activities necessary to the life-enjoyment objective of socialized and culturally determined individuals. In their consumption activities, individuals have to move between different types of institutions (the market, the firm, the state, personal relations, etc.) with the aim of successfully organizing their life-processes. Consumers are therefore potentially creative and consumption may become an important source of social and environmental innovation. Innovative behaviour involves a change in the relationship between consumers, infrastructures and institutions and its outcome may be evaluated under different criteria. The present paper suggests a comparison of three types of efficiency: ecological, economic and time efficiency. In order to illustrate the here proposed view, some environmental problems of the transportation system are discussed.

Abstract:

Abstract Numerous specialist studies allow managers to find accessible answers on how to develop and increase the autonomy of educational establishments in the type of management model. Every school head has to have a clear vision of the school and of its connection with the society it is part of. The vision of the manager must be shared with both the institution’s staff and the local community. It should be pointed out that there is no effective school if the manager can’t express this vision with the rest of the people who come into contact with the unit. Vision is the starting point for a mission assigned to the school unit by its manager. In general, the mission of the school is to integrate each pupil in society, to continually improve the performance of the educational act in good conditions and to the required standards. The purpose of this article is to outline the new challenges of the modern world and to highlight effective management methods.

Abstract:

Croatian banking sector amounts to the majority of its financial sector. Therefore, it is necessary that Croatian banks operate efficiently. In the past two decades, the Croatian banking sector went through a consolidation process that steadily decreased the number of banks and allocated the majority of assets and market share to a few large banks. A simple definition of efficiency is cost minimization and profit maximization. Therefore, a bank is efficient when it strives to minimize its costs while maximizing its profits. This paper aims to estimate efficiency of Croatian banks using the DEA methodology within the period 2014-2019. In addition, the performance indicators (return on assets, return on equity) calculated for the same period aim at comparing performance indicators to efficiency results. The results indicate that larger banks are generally more efficient in operating on the frontier. And, in comparison to performance indicators, they achieve higher levels of returns on assets and equity. Furthermore, some small banks tend to be efficient, while the benefits of being a medium bank are inconclusive since the results reveal that some medium banks have below average efficiency. Overall, average efficiency improved in the observed period, which means that the consolidation process of financial institutions creates large and efficient banks.

Abstract:

Rootstocks play a vital role in regulating the environmental adaptability and controlling the growth and development of apple trees. M9T337, an excellent apple rootstock widely used in commercial orchards, could confer dwarf tree architectures, early fruiting and suitability for high-density planting. However, the rooting ability of M9T3337 is low when it is vegetatively propagated, and researchers have not yet established an efficient micropropagation system. The present study systematically evaluated the multiplication in adventitious shoots and the in vitro formation of adventitious roots to determine the effects of the culture media and plant growth regulators of M9T337 and a rapid micropropagation system was developed. For the shoot multiplication, the highest multiplication index of 3.93 was obtained on Murashige and Skoog (MS) media supplemented with 2.0 mg/L 6-BA, 0.1 mg/L NAA and 0.3 mg/L GA3 from 12 combinations of 6-BA and NAA. Stronger and taller adventitious shoots were grown on MS supplemented with 1.8 mg/L 6-BA and 0.5 mg/L NAA. The optimal media with 100% rooting was obtained using 1/2 MS supplemented with 0.3 mg/L IBA or MS supplemented with 0.6 mg/L IBA for the rooting induction, resulting in mean rooting numbers of 13.00 and 11.33, respectively. Additionally, the effect on rooting of adding 0.3 mg/L IBA or not on the 1/2 MS and MS media was compared; the results suggested that an appropriate IBA concentration was the key to successful rooting. The rooted plantlets were acclimatised in a shaded greenhouse with an 84% survival rate. The established micropropagation system could be used for the rapid propagation of M9T337 for commercial production.

Abstract:

Management EfficiencyModern management process may be viewed as one constant series of decision making and creation of conditions for effective decision realization. In the process of organizing it is important to verify the organization effectiveness and implement corrections in order to maintain or increase this effectiveness. For the purpose of situation diagnosis and improvement of organization's results, the three-efficiency-levels approach is used (organization level, process level, workstation level). Degree of decision effectiveness (efficiency) will depend on rationality of the problem solving process. Therefore, it is necessary to determine the primary and supporting goals as well as strategies for their realization and to take care of the quality of organization's internal activities, which includes full readiness for cooperation and flexibility towards changes.
