Toward universal human papillomavirus vaccination for adolescent girls in Hong Kong: a policy analysis
Authors: Chen Ruirui , Wong Eliza , Wu Lijuan , Zhu Yuanfang 
Published: February 2020

AbstractStudies have assessed early population-level impact of human papillomavirus (HPV) vaccination programs for preventing cervical cancer. Through a case study in Hong Kong we examined stakeholder engagement and interactions to promote a universal HPV vaccination program using the Health Policy Triangle framework for structured health policy analysis. Using data from a document review and semi-structured in-depth interviews, we used thematic and stakeholder analyses to describe the process of policy formation. Given Hong Kong’s political and health system, and a mix of Chinese and Western values, stakeholders judged legitimacy of the process differently. We discuss their varied ethical stances and the role of research evidence for informing policy-making. For effective HPV vaccination policy and promotion of universal free HPV vaccination among adolescent girls, new strategies are needed to broaden acceptance of the process, to frame policies in terms of facts and values, and to connect research to policy-making and improve coalition-building.
Malaysia’s linguistic landscape and language practices in Chinese private clinics
Authors: Wang Xiaomei , Lee Jin Zhuo , Koh Yi Chern 
Published: February 2020

Abstract
This paper reports on the organization of Malaysia’s linguistic landscape and the implications of this situation
for contacts between providers of medical service and patients. The main purpose of this study is to clarify the position of
Chinese private clinics in Malaysian society and to better understand language use between Chinese medical personnel and Chinese
patients. The fieldwork focused on clinics in the Klang Valley, Malaysia and was carried out between December 2016 and March 2017.
The results reveal the complex linguistic situation in the medical domain reflecting the general hierarchical social structure in
Malaysia. Chinese patients have different wishes as regards their preferred language environment in these clinics, but generally
prefer to use Mandarin Chinese for interaction with doctors. Medical staff also tend to prefer the use of Mandarin Chinese but
also understand the need for dialect based interactions to create a feeling of harmony and belonging. The data are used to clarify
existing problems in doctor-patient interaction and contribute to the debate of communication discordance in the healthcare
domain.
Borders and bridges
Authors: Hansen Edwards Jette G. 
Published: February 2020

Abstract
This study examines the construction of linguistic identities at a time of significant political tension in Hong Kong, with a focus on Hong Kong’s three official languages: Cantonese, the most widely spoken variety of Chinese in Hong Kong; English, the longest serving official language of Hong Kong; and Putonghua, the official language of the People’s Republic of China (PRC), which became an official language in Hong Kong after the 1997 Handover of Hong Kong to PRC rule. Given the current political tensions between Hong Kong and the PRC, particularly in light of grassroots political movements such as the 2014 Umbrella Movement and the ongoing 2019 civil unrest due to the proposed introduction of an extradition treaty between Hong Kong and mainland China, the status of Hong Kong’s three languages is particularly interesting. Past research has primarily focused on the perceived value of these three languages in terms of instrumentality and integrativeness. The current study expands previous research by focusing on how the participants construct a linguistic identity of the self vs. a national language identity for Hong Kong, particularly within or in contrast to a national language identity of the PRC.
Rating L2 speaker comprehensibility on monologic vs. interactive tasks
Authors: Crowther Dustin 
Published: February 2020

Abstract
Second language (L2) scholars generally agree that pronunciation development should prioritize understandable over
nativelike speech. However, which linguistic features enable understanding lacks clarity. While monologic research indicates a
combined effect of segmental and suprasegmental measures, interactive research has emphasized a segmental focus. The current study
takes a step in addressing this divide by applying a monologic methodology to interactive speech. 20 L2 English learners completed
one interactive and three monologic tasks. 36 native listeners rated each speaker per task for comprehensibility. I additionally
coded all utterances for a series of phonological and fluency measures. Surprisingly, segmental and suprasegmental measures had
minimal impact on listerners’ ratings. Instead, ratings for the two more linguistically-constrained monologic tasks demonstrated
stronger associations with fluency measures than the less-constrained monologic and interactive tasks. This finding is likely an
effect of (a) increased cognitive task demands placed on speakers, and (b) listener familiarity with L2 English speech.
First-principles calculations of elastic constants for epsilon-carbide and the consequences
Authors: Jang Jae Hoon , Park Seong-Jun , Lee Tae-Ho , Bhadeshia H. K. D. H. 
Published: February 2020

The elastic constants of ϵ-carbide at 0 K and zero pressure have been calculated using first-principle methods. The iron to carbon ratio for the carbide is not established and may, in fact, vary between 3 and 2. As a consequence, the calculations have been conducted as a function of the chemical composition using the special quasi-random structures method. In all cases, the elastic constants obtained are consistent with ϵ-carbide being mechanically stable. The analysis indicates that in comparison with cementite, ϵ-carbide should be more brittle; that when present as a precipitate in steel, it would be less effective in participating in the overall plastic deformation, and that its coherency strain field in the surrounding matrix should be less extensive than cementite.

Hydropower’s hidden transformation of rivers in the Mekong
Authors: Bonnema Matthew , Hossain Faisal , Nijssen Bart , Holtgrieve Gordon 
Published: February 2020

Abstract
Despite efforts to understand the hydrologic impact of hydropower dams, their influence on downstream river temperatures has gone unnoticed in data limited regions. Using 30 years of Landsat thermal infrared observations (1988–2018), we identified a relationship between dry season water temperature cooling trends and dam development in the 3S Basin, a major tributary of the Mekong River. Within a year of the beginning of operations of major dams in the 3S River Basin, rapid decreases in annual average dry season river temperature were observed ranging between 0.7 ° C and 2 ° C. Furthermore, in situ water temperature observations confirmed decreasing river temperature for two major dam development events. Evidence was found that the 3S outflow has been cooling the Mekong River downstream of the confluence, by as much as 0.8 ° C in recent years. Our findings are critically important for understanding how fish and aquatic ecosystems will behave in the future as more hydropower dams are built in the Mekong River Basin.
Microbial structure of nitrogen utilizers in Populus nigra L. compost and vermicompost
Authors: Kornievskaya E , Kurovsky A , Babenko A , Petrochenko K , Sechko O 
Published: February 2020

Abstract

Eisenia fetida worms affecting the amount of bacteria from four trophic groups in poplar leaf litter vermicompost was investigated. As a control, composted and vermicomposted horse manure was used. The number of ammonifiers in the vermicomposted manure was higher than in the composted; the opposite situation was observed in poplar litter substrates – the number of ammonifiers was higher in compost than in vermicompost. Nitrogen fixers of the genus Azotobacter were detected only in vermicomposts and were absent in composts. The activity of nitrogen fixers of the genus Azotobacter was higher in vermicomposted poplar leaf litter than in vermicomposted manure. The total amount of ammonifiers and utilizers of inorganic nitrogen is considered to be an integral indicator of the quality of organic fertilizers. This indicator was independent of the presence or absence of worms and was higher in the substrates based on poplar leaf litter compared to the ones based on manure. As the amount of nitrate nitrogen (NO3-nitrogen) is larger in the leaf litter substrates than in the horse manure substrates, we recommend using composted and vermicomposted poplar leaf litter as organic fertilizer with a microbial structure, which provides enough nitrogen available to plants.

Abstract
This article assesses the economic efficiency of using Synoestrol-2% to down-calving cows for stimulate colostral immunity and non-specific resistance in newborn calves. Use of the drug positively affected the health of calves. At the same time, the immuno-biochemical and morphological composition of the blood in newborn calves improved to the first day after born: increased the level of total protein for 9.75% (p<0.05) compared to the control group of calves, albumins – 13.7% (p<0.05), alpha-globulins – 31% (p<0.05), gamma globulins – 21.8% (p<0.05), number of leukocyte increased for 17.2% (p<0.05). Ten days after birth, the content of alpha- and gamma- globulin decreased in the calves of the control and experimental groups, but it was significantly higher in the calves of the experimental group. The number of leukocytes was higher in the calves of the experimental group, mainly due to neutrophils. The first day after birth bactericidal activity of the blood serum, lysozyme activity of the blood serum, neutrophil phagocytic rate was higher compared with similar indicators calves of control group. The incidence of dyspepsia of calves of the experimental group decreased by 1.3 times, the duration of the disease was shorter by 1.7 days compared to calves of the control group. The economic efficiency of the use of the drug Sinoestrol-2% to cows was 3.12 rubles per 1 ruble of expenses.

Published: February 2020

Abstract
Sunflower is the main oil crop in Russia. Sunflower plantings occupy more than 95% of the area under oil crops and annually make 7.07% of the area under grain crops. The urgent problem is the loss of oilseeds behind the header during sunflower harvesting which, according to agro-technical requirements, should not exceed 2.5% of the actual yield. The article presents the average loss of oilseeds behind various sunflower harvesting attachments. The analysis of rationality of their use depending on the area under sunflower plantings is given. The design is offered and the scheme is substantiated of the performance of an auger-reel for sunflower harvesting attachment. The developed auger-reel is equipped with a winding, which allows reducing the acceleration of the sunflower head movement during the harvesting and minimizing the loss of oilseeds behind the header to 0.63%. The results of the production tests of the developed attachment with “Niva” SK-5-M-1 and ACROS 530 combine harvesters are presented. Their comparison with the average losses of oilseeds using different by design attachments is given.

Published: February 2020

Abstract
The relevance of the research topic is due to the problem of deterioration in the food quality market and the lack of high-quality products. The aim of the study was to deepen knowledge of food market and explore the reasons for deterioration of product quality; justification of institutional restrictions ensuring market growth is also considered. It was established that adverse changes in the external and internal competitive environment led to a sharp increase in prices of suppliers of manufactured goods without increasing purchase prices by retail chains. It was established that external changes led to an increase in prices of suppliers together with low purchase prices. This prompted to make a profit through worsening product quality. It is substantiated that there exist opportunities for the production of high-quality food. To limit the decommodification of food and create a market for high-quality products it is proposed to adopt a basic law on the food market. Legal acts are aimed at improving regulation of production, market circulation, environmental purity and genetic integrity. The novelty of the work relates to the fact that in the country with rich resources a new growth axis will be formed. This axis seems to be attractive for investment.
Justification of non-power rotational working body for “STRIP-TILL”
Authors: Smirnov P A , Smirnov M P , Alekseev E P , Prokopieva E V 
Published: February 2020

Abstract
In the last decade, the idea of narrow-band tillage for row crops has gained not only material realization, but also a real estimated framework in terms of energy and resource saving. The article presents a variant of the working body for strip tillage, as the simplest and most reliable in construction, at the same time the most effective in terms of achieving the agrotechnical quality of the treated soil. The design of the non-power rotary working body is as follows. At the maximum approaching of two symmetric afrontal and needle disks inclined from the vertical to the crossing of their rolling planes, a zone of soil destruction due to a fixed shift is formed. In this zone, the needles of the first disk make a working stroke approximately perpendicular to the direction of movement, and the needles of the second disk make a similar movement in the opposite direction in the intervals of the needles of the first disk. The soil in this area is first pinched between the needles, then destroyed, including large lumps. To exclude wear on the tips of the needles and the unstable progress of the entire non-driven rotary working body, the manufacture of needles in the self-sharpening mode is proposed, the recommended operating modes are given. An optimal variant of using a non-driven rotary working body as part of the transformer “narrow-band tillage adapter - seeder” is also proposed, on which the adapter can be aggregated with any seeder for row crops.

Published: February 2020

Abstract
The problem of conservation and reproduction of soil fertility by using unconventional organic fertilizers, particularly the replacement of the mineral nitrogen fertilizer to its organic form is discussed. The growth of the livestock industry lays the groundwork for the recovery of meat processing industry waste of horned ungulate crumbs (HAC) as fertilizer for inter-tilled crops. HAC contains about 14% nitrogen. Experiments on the application of HAC as a nitrogen fertilizer and sorption-type ameliorant – zeolite-containing tripoli were organized in 2012-2016 in the crop rotation link on the light gray forest soil of the experimental field of the FSBEI HE Chuvash State Agricultural Academy, Chuvash Republic. In this paper, the effect of the HAC-form on the optimization of nitrogen nutrition of the studied crops both separately and for tripoli having phosphorus-potassium mineral fertilizers is studied. The positive effect of HAC and tripoli on the growth and development of potato and fodder beet plants, soil biological activity, leaf surface area, yield and quality indicators of potato tubers and fodder beet root crops both in the first year when fertilizers are applied and in their aftereffect in the second year for barley yield was revealed. The study materials contribute to the practical solution of the problem of the recovery of meat processing industry waste and rational use of resources in the fertilizer system, being a guide to energy and resource conservation in agriculture.

Published: February 2020

Abstract
The article presents studies of the impact of digital inequality on the development of rural areas as socio-economic systems. The difference in the levels of socio-economic development of rural areas and cities in the transition to the information society is not smoothed, but rather increases, which threatens to turn most of the territory of the Russian Federation into one huge depressed region. Among the key factors determining the negative impact of digital transformations, the study highlights the rapid deterioration of the quality of human resources, which is a consequence and cause of digital inequality. The process of concentration of innovative potential in large cities and individual industries, which leads to the depletion of rural areas, and unpredictable transformations in agriculture, where the lack of mass application of high technologies leads to a sharp decrease in efficiency and General degradation of a number of resources, is critically comprehended. To solve this problem, the authors propose the concept of information model of digital transformation of management processes of socio-economic systems, taking into account the influence of territorial and sectoral factors of formation of resource potential of rural areas in the information society.

Published: February 2020

Abstract
The most intense trend in the modern economy is the introduction of a green economy as one of the main conditions for maintaining a balanced state of the environment for future generations. The strategy of “green” development is becoming increasingly used in different countries. Green growth is a strategy for transforming an economic system in which investments in environmental resources and services become the driving force of economic development. The success of the strategy depends not only on political will but also to a greater extent on centralized funding and planning for green programs. The need to implement the concept of a “green” economy is particularly acute in agricultural production.
