Authors: Krutko R.V.
Published: June 2020

Goal. To evaluate bred multi-marker tomato lines for a set of economic traits.

Results and discussion. The results of studying new multi-marker tomato lines in a competitive variety trial are given. Twelve lines were evaluated for the growing season length and its phases, traits of performance and chemical composition of fruits. It was revealed that according to the growing season length all the lines were early-ripening and gave yields 97-110 days after emergence. Line L-120/18 was selected by the shortest “emergence - the first fruit ripening” period (97 days) and by the shortest interphase “the first sprouts – anthesis” (52 days) and “anthesis - the first fruit ripening” (45 days) periods. In terms of performance, lines L-106/18 L-164/18 L-474/18 L-98/18 lines were the best, generating 2.6-3.5 kg of fruits per plant. The average fruit weight of the lines was lower than that of standard variety Karas and ranged from 40.5 g in line L-419/18 to 95.6 g in line L-106/18. As to the fruit number per plant (more than 24), lines L-419/18 L-164/18 L-474/18 L-473/18 L-106/18 L-98/18 L-125/18, and L-120/18 were distinguioshed. Biochemical assessments of tomatoes of the lines showed that most of the parameters under investigation were better in all the lines than those in the standard variety. The high content of soluble dry matter (6.8%) was found in line L-473/18; the total sugar content was the highest in lines L-473/18 (5.63%), L-99/18 (4.52%), L-106/18 (4.24%), L-102/18 (4.23%), and L-419/18 (4.23%); the vitamin C content was remarkable in lines L-125/18 (22.9 mg/100 g) and L-99/18 (23.0 mg/100 g); the titrated acidity was good in lines L-125/18 (0.75%) and L-474/18 (0.63%). Lines L-473/18 (15.6), L-99/18 (12.6), L-106/18 (11.8), and L-102/18 (10.8) stood out by their sugar-acid index.

Conclusions. The study of new multi-marker tomato lines in the competitive variety trial revealed their peculiarities in expression of the major economic characteristics. We selected lines that were superior to standard variety Karas by the growing season length, perfoemance and fruit quality. Lines L-106/18 (sp, Aft, c, gf), L-164/18 (u, y, gf, B), L-98/18 (sp, u, Aft, gs, gf, j-2), L-125/18 (Aft, hp-2dg, alc, u), L-99/18 (sp, u, Aft, hp-1), and L-120/18 (sp, Aft , hp-1, u, o, j-2) were offered as sources for breeding. The expediency of using these lines also lies in the fact that, in addition to economic traits, they are carriers of mutant genes that which are easily identified and inherited by Mendel's simple laws, which facilitates their combination, significantly speeds up selection of desired genotypes and generation of forms with a set of specified traits.

The aim of the article is to summarize the results of plant gene pool samples introduction into the National Plant Genebank from different countries and ecological and geographical zones for use in domestic breeding.

Results and Discussion. In 2016 – 2018, 5984 samples were introduced to the Centre for Plant Genetic Resources of Ukraine using various information sources, including 2093 samples from Ukraine and 3891 from foreign countries. The greatest samples variety was attracted by cereals, leguminous, fodder, medicinal and essential oil, vegetable and melon crops, corn. Seeds of new forms having valuable properties are attached from research and breeding institutions of Ukraine. The samples of foreign origin were most actively introduced through cooperation with research institutions of Russia, Belarus, and Moldova. A significant number of samples came from genebanks in Europe: the Czech Republic, Italy, France, Germany, the Netherlands; Asia: Kazakhstan Turkey, Israel, China as well as from South (Mexico) and North America - USA, Canada. The ways of pre-adaptation and adaptation of samples from geographically remote regions for use in Ukraine are indicated. To collect local cultural and wild-growing samples of different crops, collecting missions were carried out in the central and southern regions of the forest-steppe and northeastern regions of Ukraine during which 1641 gene pool samples were collected. For the Red Book species of plants and species that are not listed in the Red Book of Ukraine but are rare or are threatened with extinction under natural conditions, a points have been identified for possible arrangement of in situ conservation reserves. A number of objects with a rich genetic diversity of fodder and medicinal plants have been identified, on which it is necessary to monitor coenoses and ensure in situ conservation. The introduced samples were transferred for use in research and breeding programs in Ukraine.

Conclusions. The definition of a model of ecologically adapted in Ukraine genotypes of different crops that are carriers of valuable traits from countries with similar climatic conditions as well as from geographically remote regions, has made it possible to increase the efficiency of introduction and to more specifically search and attract to the National Genebank the plant samples with the necessary manifestation levels of economic and biological traits.

Authors: Krasulia T.I.
Published: June 2020

Aim. To define the priority trends of apple breeding in the southern steppe of Ukraine and to identify varieties – sources of high valuable-for-breeding indices for building up a working collection.

Results and Discussion. Spring frosts and wet weather in May-June contributing to development of the scab pathogen (Venturia inaequalis), high temperature and water deficit in the 2nd half of the growing period, when fruits grow and ripen, are the major stress weather/climatic factors for apple trees in the southern steppe of Ukraine. Therefore, the priority in breeding is given to developing varieties that would be resistant to several unfavorable factors. At the same time, commercial use of new varieties is possible provided high commercial quality indicators of fruits. High resistance of buds to spring frosts was observed in varieties Vechirnia Zoria, Moldavskoye Krasnoye, and Prima. Oligogenic varieties (genes Vm and Vf), including Harant, Skifske Zoloto, and Liberty, showed no signs of scab development. Varieties with polygenic resistance to this disease were identified; they included Vechirnia Zoria, Ornament, Carola. Drought-tolerant varieties with high water-holding capacity of leaves and their turgor restoration after wilting, including Carola, Florina, and Prima, were selected by a laboratory method. Assessment of drought tolerance in the field made it possible to enrich this group with numerous varieties. Varieties giving fruits with high commercial qualities on insufficient water availability, such as Vechirnia Zoria, Harant, Moldavskoye Krasnoye, Ornament and others, were distinguished. Varieties combining resistance to several unfavorable abiotic and biotic factors with high marketability traits of fruits were singled out. Among them. Harant, Delicious Spur, Liberty, and Prima should be mentioned.

Conclusions. The development of varieties with complex tolerance to spring frosts, drought, scab pathogen and high qualities of fruits is the priority trend in the breeding of apple trees in the southern steppe of Ukraine. Varieties - sources of individual valuable traits and their various combinations were identified. Varieties Vechirnia Zoria, Moldavskoye Krasnoye, Ornament, and Golden Resistant combine the maximum number of valuable-for-breeding features. It is varieties-sources of several traits that should make up a working collection of apple trees to increase the breeding efficiency.

Published: June 2020

Since the classiﬁcation of COVID-19 as a global pandemic, there have been many attempts to treat and contain the virus. Although there is no speciﬁc antiviral treatment recommended for COVID-19, there are several drugs that can potentially help with symptoms. In this work, we mined a large twitter dataset of 280 million tweets of COVID-19 chatter to identify discourse around potential treatments. While seemingly a straightforward task, due to the informal nature of language use in Twitter, we demonstrate the need of machine learning methods to aid in this task. By applying these methods we are able to recover almost 21% additional data than with traditional methods.
Possible Barriers to a Successful Further Diffusion of the Best Value Approach in the Netherlands: Observations of Major Misunderstandings on the Concept and Theory
Authors: Witteveen Wiebe , Van de Rijt Jeroen
Published: June 2020

In recent years Best Value (BV) has gained popularity in the Netherlands. Many clients have adopted BV after the successful application in the ‘Spoedaanpak Wegen’ projects (Fast Track Projects) by Rijkswaterstaat (Department of Public Works). The social system of users of BV is evolving. In the past years primarily the procurement community was interested in BV (where it all started), but recently risk managers and project managers are becoming increasingly aware of the philosophy. Van de Rijt & Santema (2012) observed that (potential) users of BV all have a different level of awareness of the BV methodology and that experts in BV cannot force others into the “right” or “pure” methodology. However, BV experts can reflect upon major misunderstandings in order to improve the understanding and implementation of the philosophy. In this paper, the authors elaborate on this matter. They observe ten common misperceptions in the everyday application of the Best Value approach, which may hinder a successful further diffusion of the Best Value approach in the Netherlands.

This study aimed to find out how community participation in the Village Fund program in Kemang Manis Village in the Four Lawang District in 2016 and the factors that supported and blocked community participation in the village fund program in Kemang Manis Village. The method used was qualitative so that the data obtained through interviews, observation and study of documentation and qualitative descriptive analysis techniques. The results showed that at the decision making stage, the participation of the Kemang Manis village community in the Village Fund Program in 2016 was still low because the data synchronization activities were not carried out, only the village elite community and workers as well as grant providers, were invited, attended, gave opinions, and approve the results of the meeting's decision. At the implementation stage (community participation) was quite good, it appeared in the crowded community who registered themselves as candidates for village infrastructure activities, following the work briefing and direction from the village government. At the time of implementation the community brought their own carpentry equipment, donated food and drinks, and received wages or daily work incentives, and participants of community empowerment activities received transport money. The stages of the utilization of benefits (benefits) the community felt the benefits of the results of village development. Roads could be passed by 4-wheeled vehicles, making it easier to transport agricultural produce, residents began to build houses because roads were available and land values ​​had also increased. The community had not yet been involved in the monitoring, supervision and evaluation stages, because in the planning stages of the Village RPJM and Village RKP documents the community involvement is still low. At the stage of implementation of village development the community was involved as an implementer, but the procurement and financial management and administration activities were carried out by the village government. There were no complaints from the public and information disclosure regarding the new Village Fund in the form of a Village Infrastructure development project board.

ABSTRACT

This research is motivated by the poor implementation of the maintenance of the Sirah Pulau Padang-Pampangan road, the maintenance activities have not reached the target and the condition of the road is badly damaged. This study aims to determine the management of the maintenance budget for the Sirah Pulau Padang-Pampangan road for the 2017 Fiscal Year at the Public Works and Spatial Planning Office of Ogan Komering Ilir Regency. The research method used in this study is a qualitative method. Data collection techniques carried out through observation, in-depth interviews and documentation. The theory used in this study is the principles of financial management according to Juli Sarlima, where financial management can be seen from five dimensions, namely Transparency, Efficient, Effective, Accountable and Participatory, and analysed through management aspects, namely Planning, Organizing, Implementing and Responsibility. Based on the results of research in the field shows that Transparency, Efficient, Effective, Accountable and Participatory has not been done well. The conclusion of this research is that the management of budget road maintenance for the Sirah Pulau Padang-Pampangan roads in the 2017 fiscal year is not going well. This research suggests that management of budget works well: 1) Standard Operational Procedure (SOP) for Road Maintenance activities needs to be made, 2) the need for a place for the community to participate and be involved in planning, implementation of supervision, 3) preparation of Financial Statements and Reports Accountability must be clear and detailed.
Dioscin Ameliorates Polycystic Ovary Syndrome by Inhibiting PI3K/Akt Pathway-Mediated Proliferation and Apoptosis of Ovarian Granulosa Cells
Authors: Li Xinrong , Lv Beili , Wang Haiyan , Qian Qiaohong
Published: June 2020

To understand the mechanism underlying Dioscin inhibition of polycystic ovary syndrome, we have examined its effects on ovarian granulosa cells from letrozole-treated rats. To this end, Western blot was utilized to determine changes in the levels of Bcl-2, cleaved caspase-3, caspase-3, and phosphatidylinositol 3-kinase (PI3K)/protein kinase B pathway after Dioscin treatment in letrozole-treated rats. Dioscin ameliorated polycystic ovary syndrome by reducing the serum level of testosterone and increasing progesterone levels. It also inhibited proliferation and induced apoptosis of ovarian granulosa cells in the rat model by decreasing the level of Bcl-2 and elevating cleaved caspase-3. Western blot analysis revealed that Dioscin suppressed the PI3K/Akt pathway by inhibiting p-AKT/AKT. SC79, a p-AKT/AKT activator, reversed the effects of Dioscin on the proliferation and apoptosis of ovarian granulosa cells. In conclusion, Dioscin might present a novel therapeutic opportunity for patients with polycystic ovary syndrome.

Authors: El-Ghobashy El-Hagar Mahmoud Mohamed
Published: June 2020

In this present study a theoretical investigation is used to examine the effect of different fuel cetane numbers (CNs) on reducing the ignition delay and exhaust emissions from diesel engine at certain operating conditions. The operating conditions for such diesel engine include compression ratios, engine speeds and intake pressures and temperatures. For this purpose, the fuels with 40 and 50 CN were tested in a four cycle, four cylinders direct injection (DI) diesel engine. Theoretical analyses were conducted for the standard injection pressures (150 bars); the exhaust emissions were tested at engine speeds from 4500 min-1 to 1000 min-1 at full engine load. The results showed that, at all operating conditions, the ignition delay decreases as the cetane number, compression ratio, engine speed, intake pressure and temperature are increased so that combustion efficiency is improved. Also the exhaust emissions NOX, SO2 and CO are reduced when the fuel CN is increased from 40 to 50 for the standard injection pressure (150 bars). Increases in engine torque and power output were observed when the CN is increased.

A Literature Review of the Strategic Decision-Making Context: A Synthesis of Previous Mixed Findings and an Agenda for the Way Forward

Published: June 2020

The aim of this article is to conduct a comprehensive literature review concerning the influence of contextual factors on strategic decision processes. Our literature review organizes the existing literature on contextual factors along the lines of an integrative framework for studying strategic decisions. Interestingly, the stream of research on strategic decision processes is dominated by studies showing mixed, contradictory, and inconclusive findings. The effects of each contextual factor on the strategic decision process differ substantially across the reviewed studies. This creates several opportunities for further research on the topic. The review also reveals a paucity of cross-cultural studies, longitudinal studies, and tests of complex relationships such as three-way interactions, curvilinear relationships, and mediation effects. We conclude our review by suggesting seven directions for future research and identifying several implications for theory and practice.
Value Creation and Value Appropriation in Innovative Coopetition Projects
Authors: Chiambaretto Paul , Maurice Jonathan , Willinger Marc
Published: June 2020

This article provides a formal model of the value creation-appropriation dilemma in coopetition for innovation, that is, alliances among competing firms. The model determines the levels of cooperation that maximize the profit of each firm in an innovative coopetition agreement regardless of the number of firms and their respective budget endowments dedicated to the coopetitive project. We answer the following questions: within an innovative coopetition agreement, will the partners cooperate more or less when their budget endowments change? What is the impact on profit? When is it profitable to accept a new partner into the agreement? What happens to the remaining firms when a partner withdraws from the agreement? We show that when the coopetitive budget of the focal firm increases, the focal firm allocates a larger part of this budget to value creation activities and increases its profit. In contrast, when a partnering firm increases its coopetitive budget, the focal firm reduces its budget for value creation activities to maintain a sufficient budget for value appropriation activities. We also show that the addition of a competitor with a large coopetitive budget to the innovative coopetition agreement decreases the cooperation of the focal firm but increases the profit of the initial partnering firms. In contrast, the exit of a partnering firm with a large coopetitive budget from the agreement intensifies the cooperation among the remaining firms but reduces their profit.
Scapegoating in the Organization: Which Regulation Modes?
Authors: Djabi Mélia , Sitte de Longueval Oriane
Published: June 2020

Several studies have focused on scapegoating in the organizational context. However, most have tended to enclose the protagonists in predefined roles: scapegoats are relatively passive, their colleagues persecute them, and management quickly join the persecutors. According to this scenario, the outcome ends irrevocably with the scapegoat’s isolation. The literatures in related fields have nevertheless suggested other modes of regulation, and we might question whether our representation of the organizational scapegoating process, from passive actors to automatic outcome, offers a full account of this complex phenomenon as it unfolds and is lived. We in fact do not know how organizational actors regulate the scapegoating process, interfering with and influencing its trajectory and outcome. In this article, we conceptualize this complex process by examining the active and regulating roles of its protagonists and how they hinder or even avert the violence of scapegoating. In an exploratory and qualitative study of seven cases of scapegoating in a large French company, we describe the actions of the scapegoats (combating the persecution, struggling against stigma, avoidance, and departure) and management (support for persecutors, support for the scapegoat, and ambivalent support). The articulation of the protagonists’ actions ultimately leads to four types of resolution for the scapegoat: isolation, expulsion, cohabitation, and assimilation. Two modes of regulation emerge: the first mode strengthens and catalyzes the scapegoating process, whereas the second mode prevents and channels it. By detailing the actors’ actions and their capacities to co-regulate the scapegoating process, this study moves beyond a deterministic vision of scapegoating and underlines the role of its protagonists. A research agenda is discussed.

PERAN LITERASI TEKNOLOGI INFORMASI DAN KOMUNIKASI PADA PEMBELAJARAN JARAK JAUH DI MASA PANDEMI COVID-19
Authors: Abdul Latip
Published: June 2020

Penulisan artikel ini bertujuan untuk menganalisis secara kajian literatur mengenai pentingnya literasi teknologi informasi dan komunikasi sebagai kunci dan penunjang pelaksanaan pembelajaran jarak jauh pada masa pandemi Covid-19.  Analisis pada artikel ini menggunakan empat langkah kajian literatur, yaitu pemilihan topik yang akan direview, mencari dan menyeleksi artikel yang berkaitan dengan topik, menganalisis dan mensintesis literatur, dan mengorganisasikan tulisan. Hasil kajian literatur menunjukkan bahwa pandemi Covid-19 memberikan perubahan signifikan pada berbagai sektor, termasuk sektor pendidikan. Pembelajaran jarak jauh (PJJ) merupakan salah satu bentuk penyesuaian dalam sektor pendidikan selama masa pandemi Covid-19. Pada pelaksanaan pembelajaran jarak jauh, teknologi menjadi kunci keberlangsungan PJJ yang dapat menjadi penghubung antara pengajar dan pembelajar yang tersekat dengan jarak. Namun demikian, keberadaan teknologi akan menjadi tidak termanfaatkan jika tidak dibarengi dengan pengguna teknologi yang melek teknologi. Literasi teknologi informasi dan komunikasi mencakup segala pengetahuan dan keterampilan dalam memanfaatkan teknologi, mulai dari mengenal perangkatnya, mengoperasikannya, mengolah dan mengkomunikasikan informasi. Teknologi dan Literasi TIK memiliki peran penting dalam memperlancar PJJ, menjadikan PJJ lebih efektif, memperlancar komunikasi dan kolaborasi antara pengajar dan pembelajar, serta mendorong penggunaan teknologi yang positif yang mengedepankan etika sosial yang bertanggung jawab
