Online retellings and the viral transformation of a Twitter breakup story
Authors: De Fina Anna , Gore Brittany Toscano 
Published: June 2019

Abstract
The retelling and sharing of stories is not a new phenomenon. Many narrative analysts have devoted research to these processes. But the culture of participation (Jenkins 2006) in the digital world has brought sharing to a completely new level by allowing users not only to broadcast their opinions and evaluations of a story but also to reappropriate it and recontextualize it in infinite recursions. We focus on such process of transformation of a narrative in different media and social media outlets through the analysis of the viral spread of a story posted by an individual Twitter user in 2015. Specifically, we illustrate how participation frameworks change from one retelling to another and how the original story becomes "nested" into a new meta-story centered on the twitter user as a character and on the viral spread of the story.
Interference control in bilingual auditory sentence processing in noise
Authors: Kim Jungna , Marton Klara , Obler Loraine K. 
Published: June 2019

Abstract
Listening to speech in the presence of interfering auditory stimuli is a well-studied phenomenon in second language (L2) listeners. L2 auditory processing has been associated with various individual factors, such as listeners’ L2 linguistic and contextual knowledge and L2 proficiency (Cutler, 2005). How efficiently and skillfully participants manage auditory interference may also be closely related to their ability to stay attentive to the target and suppress the irrelevant auditory stimuli. This review discusses the factors that modulate L2 auditory processing in noise and describes the underlying mechanisms of auditory interference control in bilingual individuals. Furthermore, we review the potential interaction between L2 proficiency and interference control in bilinguals.

Published: June 2019

Abstract
This review integrates recent scientific findings on the behaviour and welfare of buffalo dams during calving and the subsequent milking phase. These issues are discussed in relation to the level of welfare that buffalo dams and calves experience under different production systems. Key aspects are addressed including welfare issues related to dystocic parturitions and uterine prolapses, the formation of a selective dam-calf bonding, the habituation of inexperienced animals to the milking routine and the appropriate relationship to be developed with stock-people. All these aspects are also discussed in relation to farm profitability, in terms of calf vitality and milk production, and safety of the personnel involved in farm operations.
Influence of tip adhesion on nanoindentation and scratching
Authors: Alhafez Iyad Alabd , Urbassek Herbert M 
Published: June 2019

Abstract
Using molecular dynamics simulation, we study the influence of tip adhesion on nanoindentation and scratching. By using a model pair potential between tip atoms and substrate atoms, we can arbitrarily change the adhesion strength. For the prototypical case of a diamond tip and a bcc Fe substrate, we find that with increasing adhesion strength, the indentation hardness and also the normal hardness during scratching decreases. Even more pronounced is a strong increase of the transverse force and hence of the friction coefficient during scratching. The indent pit becomes atomically rough, and the pileup produced during scratch increases with increasing adhesion strength. On the other hand, the length of the dislocations produced and the spatial extent of the plastic zone shrinks.
Measurement of the gas temperature of neutrals in reactive plasmas by moderate-resolution OES
Authors: Miakonkikh A.V. , Rudenko K.V. 
Published: June 2019

Abstract
Measurements of gas temperature (Tg) in the low-temperature high-density plasma of SF6 containing gas mixes were performed by OES technique. The translational temperature of plasma in the ICP discharge was measured by the method of small addition of nitrogen to the fluorine containing plasmas. Moderate resolution compact spectrometer was applied to get partially resolved rotational spectra of 2+ system of the molecular nitrogen. It is shown that Tg can reach up to 1300 K, weakly depends on investigated pressure range and linearly depends on RF power in the discharge. The absolute value of the temperature differs significantly for different tested plasmas of N2, and SF6/N2. Various aspects of the effect of Tg parameter in plasma on the processes of plasma etching of semiconductor microstructures are discussed.
Emissions and emergence: a new index comparing relative contributions to climate change with relative climatic consequences
Authors: Frame David J , Harrington Luke J , Fuglestvedt Jan S , Millar Richard J , Joshi Manoj M , Caney Simon 
Published: June 2019

Abstract
We develop a new index which maps relative climate change contributions to relative emergent impacts of climate change. The index compares cumulative emissions data with patterns of signal-to-noise ratios (S/N) in regional temperature (Frame et al 2017 Nat. Clim. Change
7 407–11). The latter act as a proxy for a range of local climate impacts, so emergent patterns of this ratio provide an informative way of summarising the regional disparities of climate change impacts. Here we combine these with measures of regional/national contributions to climate change to develop an ‘emissions-emergence index’ (EEI) linking regions’/countries’ contributions to climate change with the emergent regional impacts of climate change. The EEI is a simple but robust indicator which captures relative contributions to and regional impacts from climate change. We demonstrate the applicability of the EEI both for discussions of historical contributions and impacts, and for considering future relative contributions and impacts, and examine its utility in the context of existing related metrics. Finally, we show how future emissions pathways can either imply a growth or reduction of regional climate change inequalities depending on the type and compositions of socioeconomic development strategies.

Published: June 2019

Abstract
Imports become an alternative policy to meet the domestic soybean demand. North Sumatra Province has a high dependence on soybean imports because the amount of soybean imported is greater than the amount of domestic production. The purpose of this study was to analyse the influencing factors of the soybean import volume in North Sumatera Province. The Engle-Granger Cointegration Test and the Error Correction Model (ECM) methods used to identify the factors influencing the soybean import volume in the long-term and the short-term. The results concluded that the soybean import was significantly influenced by the domestic soybean production, the exchange rate, and the soybean price ratio. In the long-term, the soybean price ratio significantly influences the soybean import volume. While in the short-term, exchange rate and soybean price ratio significantly influence the soybean import volume.
The impacts of harvest on price index of producer (Case study: Hamparan Perak Subdistrict, Deli Serdang Regency, Indonesia)
Authors: Salmiah  , Herawati  , Khaliqi M 
Published: June 2019

Abstract
Producers price index is a means of measuring the welfare of farmers, so calculating producers price index can know the level of welfare of farmers. This is related to the purchasing power in the fulfilment of household consumption needs. One of the classic problems that rice farmers often encounter is the drop in the selling price of grain/rice during harvest time, and rising prices when outside the harvest. The research objective is to analyse the impacts of harvest on producers’ price index. Producers price index at harvest time is lower than non-harvest, so that farmer’s welfare during harvest time is decreasing seen from decreasing of farmers’ producers’ price index of the rice farmer. Low producers price index due to high harvest resulted in decreasing consumption of home staple foods.

Published: June 2019

AbstractPlant vegetables in Gajah and Bulan Baru Villages usually used excessive pesticides, that cause a negative impact on consumers and farmers who apply it. Some influential factors include in the used of pesticide are prices of pesticides, output prices, the size of land and farming experience. This study wants to analyze the influence of these variables on pesticide application. Sample in the study area was carried out by the census, 20 mustard farmers, 35 tomato farmers, and 35 cabbage flower farmers. To solve the study problem, the linear regression function method is used. Pesticide prices have a negative and significant effect on the use of pesticides in vegetable crops mustard, tomatoes and flower cabbage. Land area variables have a positive and significant effect only on mustard plants. Other variables were found to have no significant effect on pesticide use. It is recommended to the government to influence the price of pesticides so that it can reduce the use of it and at the same time introduce an integrated pest protection system and encourage the use of biological pest control.

Abstract
This study aimed to determine the effect of spermatozoa separation on local goats using different percoll compositions for abnormalities, mortality, and motility. Percoll is a tool for efficient in biochemistry. It is used for the isolation of cells, organelles, or viruses by density centrifugation. The material in this study was four local goats, aged 1.5 years. The treatment in this study consisted of: P1 = Percentage of Percoll: percentage of M-199 + aquabidestillata + Bicarbonate [10:90], P2 = [20:80], P3 = [30:70] and P4 = [40:60]. The experiment was carried out six times and the semen collection interval every two days. The design of this study uses a random block design to check motility, mortality, and abnormalities. The result of this study is the separation of goat spermatozoa using different percoll compositions affecting motility, mortality, abnormalities, but no effect on sperm abnormalities. Percoll can increase the dominance of Y sperm with a high proportion in P3 and P4 90.3 ± 5.8 and 87 ± 5.2 present, respectively. Additional percoll composition can reduce motility and increase mortality, but still good enough for Artificial Insemination [AI] implementation

Published: June 2019

Abstract
Having a green environment, such as urban park as green open space (GOS), is one way to reduce global warming in urban areas. City development and population growth, however, have led to a decrease in GOS. The research aimed to (1) identify the characteristics and activities of the community utilizing the urban park, (2) examine the type and level of community’s participation in the urban park preservation and (3) analyse the relationship between the `community’s characteristics and participation level in the urban park. Employing the purposive sampling method, the researcher chose a city park with various facilities and the high rate of the visit. The respondents were visitors chosen through the accidental sampling method. The characteristics of the community that utilizes urban parks are very heterogeneous from factors: age, gender, education, social status, economic status, attitude/behaviour, and knowledge. Community activities in utilizing and preserving urban parks are very diverse (sports, leisure, and preservation activities such as maintaining the cleanliness of the park). Community participation in utilizing and preserving is included in the medium (quite participating) category. Significant factors with community participation in the preservation are factors of education, knowledge, and attitudes of the community.

Abstract
Mangrove forests are wetland resources in coastal areas that important role in supporting of life. However, in recent decades, many mangrove forests have been degraded or lost, mainly due to the conversion of mangroves into ponds. Mangrove restoration activities on ex-pond lands have begun in recent years on the eastern coast of North Sumatra. This study aimed to measure the recovery of mangrove species through restoration activities on ex-pond lands and to know the composition of the restored mangrove forests at the eastern coast of North Sumatra. A total of 30 sample plots, each plot size of 10m by 10m, have been established at each age of mangrove stands (5-9 years) and secondary forests. All trees with the diameter (DBH) ≥ 2 cm in the sample plot were identified and measured the DBH. Overall, there were 14 mangrove species in all sample plots, equivalent to 42.42% of all true mangrove plants found in Indonesia. This result indicated that mangrove restoration has succeeded in restoring mangrove species diversity. Therefore, the mangrove restoration on ex-pond land needs to be promoted in an effort to restore various mangrove functions for community and coastal resources resilience.

Physicochemical characterization of water-soluble polysaccharide of Pachyrhizus erosus L. with fermentation assisted extraction method
Authors: Rusmarilin H , Hilman A 
Published: June 2019

Abstract
Water-soluble polysaccharide (WSP) is one of a complex chemical content contained in Pachyrhizus erosus L. (PeL). A recent study was examined the effect of FAEM with aqueous and Saccharomyces sp. In this study used a completely randomized design with two factors i.e. water extraction with extracting water addition on the amount of starch used (1:0.5; 1:1; 1:1.5; 1:2) and FAEM with distilled water, Saccharomyces sp and Rhizopus sp. Interestingly, dextrose equivalent of WSP-PeL (DE = 4) showed increased significant effect of FAEM with Rhizopus sp than both distilled water and Saccharomyces sp. Although degree of polymerization and total sugar just showed significant effect, WSP-PeL (DPav = 24) has a good solubility (SO = 83%) and viscosity (µ = 0.973 cP). These findings suggest that due to the viscous properties of WSP-PeL can inhibits the absorption of excessive macronutrient and decrease blood sugar levels, derived from fermentation WSP-PeL in the colon to produce Saturated-Chain Fatty Acid (SCFA).
