Published: May 2020

This study focuses on efforts to implement Government Decree No. 49 of 2018 concerning civil servants with employment contracts (P3K) in northern Aceh. This study uses descriptive qualitative research methods using data collection methods using observation, interviews, and documentation. The results showed that the government's efforts to implement Government Decree No. 49 to 2018 regarding Civil Servants with Contract of Work (P3K) is carried out with the first phase receiving first aid from PTT staff and the agriculture department, while not accepting it for other groups, although in limited circumstances due to local budget constraints. P3K is very useful for the government in filling gaps in various government institutions or institutions. For the community itself, there are several benefits related to P3K, namely by having multiple records, the income earned will be the same as for a civil servant, will receive the same benefits as a civil servant, the application age is higher and can be reduced to the maximum retirement age.

People’s Perception about Quarantine and its Impact on Occupational Stress: Community-Based Online Survey Following Covid-19 Outbreak in India
Authors: Mukherjee Subhadeep
Published: May 2020

COVID–19 has caused havoc almost throughout the world and India is also a strong victim of the same as the number of infected/positive cases is increasing drastically day by day. Quarantine i.e. a restriction on the movement of people which is intended to prevent the spread of disease is an unpleasant experience for those who undergo it. Separation from the loved ones, loss of freedom,uncertainty over the disease status, and boredom can create dramatic effects. Occupational stress ofJob Stress refers to the job-related nervousness and anxiety which affects the emotion and/or physical health of the people.This paper is a modest attempt to understand the people’s perception about quarantine and its impact on Occupational Stress due to the outbreak of COVID-19 in India.Data have been collected from 159 respondents by circulating the questionnaire through electronic mode. The collected data have been analysed by applying Structural Equation Modelling (SEM).The findings reveal that there is no significant impact on occupational stress by people’s perceptionof quarantine.
Why and how faculty adopt learning analytics: Wide-scale adoption through a diffusion of innovation lens
Authors: Arthars Natasha , Liu Danny
Published: May 2020

While there is a broad consensus around the potential for learning analytics (LA) to positively affect education, widespread adoption of LA in higher education is lacking. LA research has produced frameworks supporting policy development; however, many of these top-down approaches focus on managing resistance to change (Macfadyen, Dawson, Pardo & Gaševic, 2014). In this chapter, we view adoption as occurring at the level of individual faculty and staff who may use LA day-to-day, and diffusion as the higher-level group phenomenon that focuses on the ways in which an innovation spreads (Rogers, 2003). We examine bottom-up and widespread diffusion of an LA platform, the Student Relationship Engagement System (SRES), through an Australian university. Using two elements of Rogers’ model of diffusion of innovations, innovation and communication channels, we explore diffusion of SRES through the lens of teachers’ experiences. Our findings highlight the strength of a bottom-up approach based on LA fulfilling unmet teachers’ needs, leading to organic growth of champions that co-create value in use of LA.
EVALUATION OF THE RATIONALITY OF ENTERPRISE POTENTIAL MANAGEMENT
Authors: Shchebel A.
Published: May 2020

The potential of the enterprise may have a number of components that are heterogeneous in their economic and managerial nature. This requires the selection of criteria that would be common to assess all components of capacity. From the standpoint of the resource approach, such criteria could be the cost of resources to build the potential of the enterprise, as well as the value created by using existing capacity. This criterion is easily consistent with the goals of formation and implementation of the potential of the enterprise, and therefore can have a quantitative and temporal dimension of achievement. The cost of resources is a cost measurement of the criterion. In turn, time, on the one hand, is one of the dimensions of the selected criterion, and, on the other hand, a separate criterion. After all, the same result, which is obtained for different periods of time, usually has a different assessment. It is substantiated that the assessment of the rationality of enterprise capacity management should be carried out on the basis of comparing the cost of resources that were involved in the formation of potential with the value created as a result of its use. It is proved that the significance of the difference between these values depends on the time factor. Reducing the analyzed period and increasing the difference between the studied values increases the rationality of management. Applying the provisions of the theory of neural networks, a regression model is constructed, which assumes the use of a recurrent function. This ensured the accuracy of forecasting the resulting parameters and increased the informativeness and objectivity of the proposed method.
Asymptotic Reverse Waterfilling Algorithm of NRDF for Certain Classes of Vector Gauss-Markov Processes
Authors: Stavrou Fotios , Skoglund Mikael
Published: May 2020

In this paper, we revisit the asymptotic reverse-waterfilling characterization of the nonanticipative rate distortion

function (NRDF) derived for a time-invariant multidimensional Gauss-Markov processes with mean-squared error (MSE) distortion in [1]. We show that for certain classes of time-invariant multidimensional Gauss-Markov processes, the specific characterization behaves as a reverse-waterfilling algorithm obtained in matrix form ensuring that the numerical approach of [1, Algorithm 1] is optimal. In addition, we give an equivalent characterization that utilizes the eigenvalues of the involved matrices reminiscent of the well-known reverse-waterfilling algorithm in information theory. For the latter, we also propose a novel numerical approach to solve the algorithm optimally. The efficacy of our proposed iterative scheme compared to similar existing schemes is demonstrated via experiments. Finally, we use our new results to derive an analytical solution of the asymptotic NRDF for a correlated time-invariant two-dimensional Gauss-Markov process.
Are Groote Schuur Hospital anaesthesiologists burnt out? A cross-sectional study of prevalence and risk
Authors: Groenewald MB , van Nugteren J , Parker R
Published: June 2020

Background: Burnout and physician wellness are becoming increasingly topical. While some surveys have been performed with South African anaesthesiologists, these have been conducted in limited samples. While burnout is often measured, there is a paucity of research on contributory risk and protective factors.

Method: A contextual, prospective, cross-sectional study was conducted. The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and the Areas of Worklife Survey (AWS) were used to assess burnout and contributory organisational risk factors amongst state-employed anaesthesiologists working at Groote Schuur Hospital.

Results: Out of a possible 127 members of staff (medical officers, registrars and consultants), 81 responded with 75 completing the full survey (59% response rate). Only 4% of respondents were classified as “burnt out”, defined as scoring high in all three domains of burnout: high emotional exhaustion and depersonalisation and low personal accomplishment. However, 67% of respondents scored high for at least one of the components of burnout, indicating the majority of the respondents are at risk for developing clinically significant burnout. The AWS showed that respondents found their workload inappropriate. However, responses for the categories of control, reward, community, fairness and values were all in the acceptable range.

Conclusion: While the overall rate of burnout was low, the majority of respondents were at risk for developing burnout. High perceived workload appeared to be a particular contributory factor. Protection against burnout in this group may be provided by a combination of few organisational risk factors together with feelings of personal accomplishment.
Measures of weed control by means of environmentally friendly technologies in summer-autumn period
Authors: Kurdiukova O. , Tyshchuk O.
Published: May 2020

Goal. To select criteria for optimal solutions for calculating techniques of effective control of weeds in the summer-autumn period, taking into account their biological groups, the level of weed infestation and harmfulness.

Methods. The experiments were carried out in a stationary field crop rotation, laid down in 2010. Carrying out the experiment and determining weed infestation was performed according to generally accepted methods. To process data and criteria for optimal combinations of weed control methods, the calculation method was used.

Results. The essence of the optimal solution for controlling weeds in the summer-autumn period is as follows. The period of time, during which effective control of weeds can be carried out is determined. This is the period from harvesting the crop to the end of the weed growing season. The number of possible agro-technical technique of control is taken into account. It is assumed that for the emergence of annual seedlings or the restoration of the organs of vegetative propagation of perennial weeds, an average of 15 days is required. The possible harm in the given field of various biological groups of weeds is calculated in points by multiplying the actual weed infestation in points by the value of their harmfulness by rank. A table is compiled of the ranks of the effectiveness of agro-technical control techniques for each biological group of weeds. The most effective individual weed control techniques or their combination are selected. Each technique or combination thereof is evaluated and summing up the results; effective methods for controlling weeds are determined by indicators of the least residual damage. In order to determine the reasonability of increasing the number of agricultural practices, the conditional weed harm score is calculated by dividing the sum of the results by the square of the number of techniques. A decrease in the conditional score with an increase in the number of agro-technical measures shows that a further increase in the number of weed control methods is impractical.

Conclusions. In the system of ecologically safe farming, the main attention in the weed control system belongs to summer-autumn agro-technical techniques. Calculation of such weed control in specific soil and climatic conditions can significantly increase the effectiveness of both individual agricultural methods and their combinations.

Published: May 2020

Goal. Paulownia felines — Paulownia tomentosa L., a promising bioenergy crop for our country. In the early stages of organogenesis (juvenile and immature), young plants of the peacock sprout easily suppress weeds. Therefore, young plantations of such a promising bioenergy crop need reliable and effective protection against the adverse effects of weeds. Method. Weeding processes for young peacock plantations in the small field experiments were conducted in 2018—2019. on the experimental lands of the Yaltushk SSS IBEK and the Central Bank of NAAS The area of the plots is 36 m2, the area of the plot is 25 m2. Repeat studies — 4 times. Placement of sites is regular in two tiers. Seeds and young plants (seedlings) of Clone 112 were used for growing on the plots. Results and Discussion. Contamination of plantations was mixed. The records, carried out on 01.06, recorded the presence of seedlings of Echinochloa crus-galli (L.) Pal Beauv, Setaria glauca (L.) Pal.Beauv, Chenopodium album L., Sinapis arvensis L., Thlaspy arvense L., Polygonum scabrum Moench., mustard beetle, Polygonum convolvulus L, Solanum nigrum L. The number of weeds averaged 89.5 pcs/m2. The largest number of seedlings was recorded in millet rooster 12.4pcs/m2, mouse gray — 10.3 pcs/m2, white swans — 8.7 pcs/m2, bear­ded birch — 7.3 pcs/ m2, talaban field — 7.1 pcs/m2. By the third decade of August, their number had increased to 134.0 pieces/ m2. Conclusions. Under the conditions of co-vegetation of young peacock-planted plants with weeds, the height of their plants by the second decade of September averaged 23.6.cm. The height of crop plants that vegetated without adversely affecting the presence of weed plantations (4 consecutive manual weeding) averaged 63.8 cm or 2.7 times greater. Such a negative impact requires the implementation of protection measures for young plants.

Authors: Makuch Y. , Moshkivska S. , Smih V.
Published: May 2020

Goal. Search and evaluate the effectiveness of herbicides and their compositions in chickpea crops. On the basis of research to prepare a comprehensive system of protection of chickpea crops from the presence of weeds, which ensures high yields and is economically and environmentally feasible in the conditions of the Right-bank Forest-Steppe of Ukraine.

Methods. The experiments were based on the following scheme: Factor A (weed protection): 1. Net control; 2. Harsh control; 3. Fabian, D.Sc. 0.1 kg/ha; 4. Bazagran, bp — 2.5 l/ha; 5. Reiser, k.e. 2.0 l/ha. Factor B (seeding rate): Seeding rate, thousand pieces / ha —500; 600; 700.

Results. One way to increase the competition of chickpea plants with weeds can be to increase the stocking density of cultivated plants. It is also known that the combination of several methods of crop care contributes to the overall increase of their effect. By identifying a critical period of competitive interaction between chickpeas and weeds, it is possible to take action on the latter before they cause significant damage to the crop. Competitive reciprocity and harmfulness of weeds in chickpea crops is observed throughout the entire period of crop development. A significant decrease in productivity is observed in the presence of 10 weed plants per square meter. Increased weed density of up to 25 pc/m2 showed a 23.7% decrease in crop yield.

Conclusions. On the basis of the conducted researches it is possible to make a generalization that in the conditions of humus soils of the Right-Bank Forest-Steppe of Ukraine, when applying herbicides on chickpea crops, the best results in weed control were obtained with the introduction of Fabian, dr. application rate of 0.1 kg/ha and Bazagran, pp. 2.5 l/ha. The most favorable conditions of formation of biological productivity and realization of high level of productivity of chickpea plants are observed at the norms of sowing of seeds of 600 thousand pieces/ha.

Authors: Chernelivska О. , Dziubenko І.
Published: May 2020

Goal. Is to determine the species composition of weeds in Miscanthus giganteus plantings, their impact on biomass productivity and the development of an effective protection system. Methods. Field experiments, laboratory agrochemical studies, mathematical and statistical — to evaluate the reliability of the obtained data. Results. At the beginning of the first year of vegetation in the miscanthus crops, the type of weed was mixed, with a large predominance of annual monocotyledonous species 91.1—93.6%. But in the second (70.1—85.3%) and the third (51.1—79.8%) years of vegetation, dicotyledonous species prevailed, while in the fourth, the monocotyledonous species (55.6—64.8%) had a slight advantage. In the first year of vegetation the weed was quite high and amounted to 1156 p./m2, in the second year — 873 p./m2, it decreased to 380—386 p./ m2. On the variants of application of herbicides for the second and next years, a decrease in the number of weeds by 41.3—64.5% compared with the weed pollution control and depending on the year of vegetation was observed. In the conditions of co-vegetation of weed plants with the weeds, the largest mass was formed by the Chenopodium album L. (930 g/m2 in the first year and 93 g/ m2 in the fourth year), Amaranthus retroflexus L. (455 g/ m2 and 60.6 g/ m2), Artemisia annua L. (280 g/m2 and 29.1 g/m2) and annual monocotyledonous Echinochloa crus-galli (L.) Pal. Beauv. (225 g/ m2 and 17 g/ m2) and Setaria glauca (L.) Pal. Beauv (360 g/ m2 and 15.4 g/ m2). Weed pollution control on miscanthus crops helped to increase the biomass yield in the first year of vegetation to 2.6—2.7 t/ha of wet weight, to the fourth — up to 36.3—37.4 t/ ha. In the Weed pollution control, only 0.5 t/ha were obtained in the first year of vegetation, while in the fourth year it was 22.1 t/ ha. Conclusions. A mixed type of weed was found on the landing of Miscanthus giganteus, with 19 species from 12 families. Application of herbicides Task Extra and Master Power weed pollution reduction by 83.3—99.2%, which made it possible to improve the conditions of growing and development of Miscanthus giganteus plants and to obtain a dry biomass yield of 20.0 t/ha for the fourth year of vegetation.
The application of 1.8-naphthalic anhydride to control ALS-herbicide resistant barnyardgrass with graminicides
Authors: Schwartau V. , Mykhalska L.
Published: May 2020

Goal. Investigate the possibility to use 1,8-naphthalic anhydride metabolism inductor to control acetolactate synthase (ALS) inhibitor-resistant biotype of common graminicides of aryloxyphenoxypropionic acid class in rice.

Methodology. The interaction of 1,8-naphthalic anhydride and fenoxaprop-p-ethyl on variety Vikont rice plants was studied under laboratory aseptic conditions. The data were statistically processed.

Results. In Ukraine we have identified the biotype of resistant to herbicide ALS inhibitors Echinochloa crus-galli, which is cross-resistant to widely used herbicides — ALS inhibitors of the following chemical classes: imidazolinones (imazamox, imazapyr), sulfonylurea (nicosulfuron), triazolopyrimidines (penoxsulam). The possibilities of chemical control of weeds in rice, corn, sunflower, etc. crops are significantly limited. Multi-resistance of this weed biotype to herbicides — inhibitors of photosynthesis, mitotic cycle, 5-enolpyruvylshikimate-3-phosphate synthase, acetyl-CoA-carboxylase, protein synthesis — has not been detected. Therefore, the use of graminicides of aryloxyphenoxypropionate class is promising for the control of this ALS-resistant biotype of Echinochloa crus-galli. To increase the selectivity of fenoxaprop-P-ethyl application to rice plants, we propose to treat the seeds of the crop with the inductor of xenobiotics metabolism in plants — 1.8-naphthalic anhydride before sowing. When using 1.8-naphthalic anhydride in concentrations of 10-5 M, phytotoxicity of fenoxaprop-P-ethyl in concentrations of 10-6 and 10-5 M to rice plants is effectively reduced.

Conclusions. The use of 1.8-naphthalic anhydride is promising for increasing the selectivity of fenoxaprop-P-ethyl for rice plants and allows the development of technologies using graminicides of aryloxyphenoxypropionate class to control ALS-resistant biotype of Echinochloa crus-galli in crops. Also, it is necessary to pay attention to the problem of ALS-resistant weed biotype proliferation control in agrophytocenoses in regions of Ukraine.

Published: May 2020

Non-active students are students who do not attend the lecture process and do not pay tuition administration fees within two semesters or more. Reports on students who are not active will have an impact on the quantity of tertiary institutions. Students who are not registered in non-active students will potentially be expelled or dropped out. For this reason, this research was conducted to explore information on potentially non-active students by applying data mining science with the Decision Tree method and C4.5 algorithm. The tested data were sourced from Triguna Dharma Medan College of Information and Computer Management (STMIK). The results of the study get prediction rules for student data that are potentially non-active with a very good degree of accuracy. So this research can be used to avoid students dropping out unilaterally.

The enormous potential supply of energy in central Asia offers an excellent opportunity to establish international energy-sharing agreements, mitigate political instability, and improve regional socio-economic development. Pakistan and India have increasingly relied on energy imported from Middle and Central Asia to meet frequent energy shortages. Afghanistan has played a central role in recent efforts to balance energy trade among regional countries with an emerging opportunity as an emerging energy hub. This study considers what energy trade policies and strategies are needed to transform Afghanistan from energy consumer to energy provider. This analysis summarizes multi-disciplinary approaches that target geopolitics, economic, trade, management, institutional, environmental, and technical aspects. This study avoided a commentary description of the subject. The overriding objective of this study is addressing key solutions to enable Afghanistan as a leading stakeholder of the energy hub in the region countries. The finding of this study is outlined in 30 recommendations. Beneficiaries and stakeholders also express increasing concern about Afghanistan’s current security and political stability. This brief study can inform students, researchers, scholars, and interested policymakers with the recent trends and future outlook.

Madrid/Brujas/Toledo
Authors: Litvak Lily
Published: May 2020

La formación de la metrópolis en Europa durante el siglo XIX fue la puerta de la modernidad. La ciudad determinó una nueva economía, formas de transporte y de comercio, y cambió las formas de vida y de comportamiento. En este ensayo se estudia como en Madrid, durante la segunda mitad del siglo XIX se hicieron ver los fracasos y problemas del nuevo urbanismo; el desplazamiento de la población rural hacia chabolas indigentes, la formación de una población lumpen plagada por la miseria, el alcoholismo y la prostitución, la amenaza de las multitudes y el temor a la decadencia. Para muchos escritores, el escape estético fue el refugio en la “ciudad muerta” un conjunto monumental que escapaba a la modernidad y al progreso. El tema que tomó forma en la novela de Georges Rodenbach, Brujas la muerta consagró a algunas ciudades españolas como ciudades muertas, y sobre todo a Toledo exaltada por su paisaje, antiguos edificios y el arte de El Greco.
