Development of a Five-Parameter Model to Facilitate the Estimation of Additive, Dominance, and Epistatic Effects with a Mediating Using Bootstrapping in Advanced Generations of Wheat (Triticum aestivum L.)

As a result of two crosses among three local varieties of wheat, five populations (P1, P2, F5, F6 and F7) were used as parents and grown during two successive seasons; 2016/2017 and 2017/2018. To estimate five types of gene action (e.g., mean effects, additive, dominance, additive × additive, and dominance × dominance), five formulas were developed from with algebraic solution, algebraic proof, and mathematical proof. Besides, to test adequate of a simple additive-dominance model, three formulas A, B, and C scaling test were developed. The path analysis method by PROCESS Macro, AMOS, and Bootstrapping was employed to assess the relationships between grain yield/plant (GYP) as the dependent variable and each one of the number of spikes (NS) and 1000-grain weight (TW) as the independent variables. The results show that there are eight validated equations used to estimate the scaling test (A, B and C) and five types of gene effects (m, a, D, I and L), respectively. Confidence interval using Bootstrapping results indicate that TW was played as the partial mediator between NS as an exogenous variable and GYP as an endogenous variable. Generation means analysis is a relatively simple and statistically reliable tool suitable for the fundamental estimation of different genetic influences.
Synthesis and characterization of functional polyethylene with regularly distributed thioester pendants via ring‐opening metathesis polymerization

Four kinds of functional polyethylene carrying thioester pendants were synthesized via ring-opening metathesis polymerization (ROMP) of alkyl cyclopent-3-enecarbothioate catalyzed by a ruthenium-based commercial catalyst and subsequent hydrogenation of the ROMP products (alkyl = ethyl, n-butyl, n-octyl, or n-dodecyl). In these polymers the pendant alkyl thioester groups are precisely distributed along the backbone on every five methylene carbons. Chain structure, molecular weight and molecular weight distribution of the polymers were characterized by 1H and 13C NMR, and GPC. The ROMP reactions all reached high monomer conversions, and hydrogenation of the ROMP products were exhaustive. Thermal transitions and side chain crystallization behaviors of the polymer were investigated and characterized by DSC and TGA. Glass transition temperature and melting temperature of these polymers were higher than the counterparts containing ester pendants. TGA analysis indicated that all the thioester-containing polymers exhibited moderate thermal stability, and the sulfur-containing polymers show slightly lower thermal stability than their counterparts without sulfur. The new family of functionalized polyethylenes could be used as models of ethylene-thioacrylate copolymers, and find applications as novel functional materials. © 2017 Wiley Periodicals, Inc. J.

The Effect of Spatial Location of Fermentation Pit on Prokaryotic Community Diversity in Pit Mud for Chinese Strong-Flavor Baijiu Production

Background Chinese strong-flavor baijiu (CSFB) accounts for more than 70% of all Chinese liquor markets. Diverse microbes in pit mud found in the fermentation pit play a key role in CSFB production. However, the effect of spatial location on the diversity and structure of the microbial community in pit mud is still poorly understood Results Prokaryotic microbes in different pit mud（4- and 40-year）were analyzed by using Illumina MiSeq sequencing of 16S rRNA gene. The samples were collected from pit mud that was 4 and 40 years old in the top, middle, and under parts of the cellar walls and at the bottom of them. The results showed there was no significant difference (p>0.05) in the physicochemical factors, the Observed OTU, and α-diversity between the pit mud of two different ages. The index of the 4-year-old pit mud was lower (except for total acid, which was higher than) than that of the 40-year-old pit mud. The pH, total acid, Observed OTU, Chao 1, ACE in the 4-year-old pit mud (in the top and middle part of the cellar wall) and the 40-year-old pit mud(in the top part of the cellar wall) had significant (p<0.05) difference. At the phylum level, Firmicutes (56.70%) and Bacteroidetes (26.56%) accounted for more than 80% of the overall level. For the 4-year-old pit mud sample, the dominant genuses at each location were Proteiniphilum, Lactobacillus, and Caproiciproducens, while for the 40-year-old pit mud, there were 10 common genuses accounted for more than 50% of the dominant genuses in different pit mud belong to Clostridia. The RDA analysis results showed that 85.71% of the dominant bacteria positively correlated with pH, and especially the most correlated with the total acid and available phosphorus, so its content was significantly related to the dominant bacteria (p<0.01). Therefore, it inferred that the total acid and available phosphorus were the main physicochemical factors that affected the spatial distribution of prokaryotic microbial communities in the pit mud of cellars from the liquor distillery. Conclusions Comparing the young pit mud and the old pit mud, the structure and physicochemical factors of the prokaryotic microbial community in pit mud from Henan liquor-making company changed, and the changes occurred in the spatial location of different pits. Clostridia, which accounted for more than 50% of all types of pit mud, were responsible for the effect of total acid and available phosphorus on the microbial community. Based on the above, it provides a theoretical basis for Henan liquor-making companies in maintaining pit mud. Keywords: fermentation pit mud; spatial heterogeneity; microbial community; physicochemical factors; Chinese strong-flavor Baijiu.
Differences in AChE and BChE Enzyme Activation Levels in Liver and Brain Tissues in Rainbow Trouts Exposed to Different Bacterial Diseases

: In this study, symptomatic fish samples were taken from rainbow trout farms. Isolation and identification of agents isolated from fish samples were made. DNA isolations from different purified colonies were carried out with the mericon bacterial DNA kit. Real - Time PCR procedure was performed by using universal bacterial primers. Molecular identifications were performed by blasting the nucleotides obtained by sequence analysis of PCR amplicons. Spectrophotometric measurements were performed at 412 nm wavelengths for AChE activity and 412 nm for BChE activity from liver and brain tissues of fish samples. The activity differences of different disease factors among themselves and according to the control group were examined.

Over 98% similarity was observed as a result of sequencing analysis
Influence of Parasitic Resistances on the Input Resistance of Buck and Boost Converters in Maximum Power Point Tracking (MPPT) Systems

DC/DC converters are widely used in photovoltaic (PV) systems to maximize the power drained from solar panels. As the power generated by a PV panel depends on the temperature and irradiance level, a converter needs to constantly modify its input resistance to remain at the maximum power point (MPP). The input resistance of a converter can be described by a simple equation that includes the converter load resistance and the duty cycle of the switching signal. The equation is sufficient for an ideal converter but can lead to incorrect results for a real converter, which naturally features some parasitic resistances. The goal of this study is to evaluate how the parasitic resistances of a converter influence its input resistance and if they are relevant in terms of MPPT system operation.
“This is not a nice safe space”: investigating women’s safety work on Tinder

ABSTRACT As dating app use continues to rise, so too do women’s experiences of intrusion in digital dating contexts. The extent to which dating apps facilitate intimate intrusions—defined in this article as behaviour that makes women feel uneasy, uncomfortable, or unsafe—has been the subject of burgeoning scholarly and media attention. While this research provides important evidence for the range of intrusions women experience on dating apps, to date, little is known about how women protect themselves in digital dating contexts. Drawing on qualitative interview and walkthrough data, this research investigated the strategies women employ to protect themselves—referred to throughout this paper as “safety work”—from men’s intrusive behaviour on the dating app Tinder. Findings from this paper demonstrate the range of online and offline strategies women employ to respond to, avoid, and cope with men’s violence. Given the burden placed on women to protect themselves, this paper argues that women’s safety work limits their ability to participate freely on dating apps.
A Rapid Assessment of the Marine Megafauna Biodiversity Around South Bali, Indonesia

A low-cost, small-boat, rapid assessment survey was conducted on the waters off the southern Peninsula of Bali. The objectives were: (1) to conduct an inventory of cetacean species in the study area; (2) to map cetacean distribution to inform the design of the Badung MPA; (3) to estimate relative abundance of cetaceans and record information on presence and distribution of other marine megafauna; and (4) to train observers in the use of distance sampling methods. The survey adopted a “training while doing” approach to build local capacity for marine biodiversity monitoring, while collecting a snapshot of data to assess species richness and distribution. The survey accomplished its first two objectives, but due to violation of underlying assumptions, had mixed success with the third objective. Our survey revealed that the waters off the southern Peninsula of Bali support a rich cetacean fauna, with at least seven cetacean species, other marine megafauna, and avian species. Seven cetacean species found on our survey include: spinner dolphin (Stenella longirostris), pantropical spotted dolphin (Stenella attenuata), Fraser’s dolphin (Lagenodephis hosei), Risso’s dolphin (Grampus griseus), bottlenose dolphin (Tursiops sp.), Bryde’s whale (Balaenoptera edeni), and sperm whale (Physeter macrocephalus). Density estimates were low for all whales combined, but seem implausibly high for dolphins; likely due to violation of assumptions of distance sampling methods. Future surveys should include sufficient time for training to generate reliable abundance estimates. A dedicated bycatch study is needed to understand sustainability of bycatch mortality relative to reliable abundance estimates.
Global Sensitivity Analysis with Mixtures: A Generalized Functional ANOVA Approach

This work investigates aspects of the global sensitivity analysis of computer codes when alternative plausible distributions for the model inputs are available to the analyst. Analysts may decide to explore results under each distribution or to aggregate the distributions, assigning, for instance, a mixture. In the first case, we lose uniqueness of the sensitivity measures, and in the second case, we lose independence even if the model inputs are independent under each of the assigned distributions. Removing the unique distribution assumption impacts the mathematical properties at the basis of variance‐based sensitivity analysis and has consequences on result interpretation as well. We analyze in detail the technical aspects. From this investigation, we derive corresponding recommendations for the risk analyst. We show that an approach based on the generalized functional ANOVA expansion remains theoretically grounded in the presence of a mixture distribution. Numerically, we base the construction of the generalized function ANOVA effects on the diffeomorphic modulation under observable response preserving homotopy regression. Our application addresses the calculation of variance‐based sensitivity measures for the well‐known Nordhaus' DICE model, when its inputs are assigned a mixture distribution. A discussion of implications for the risk analyst and future research perspectives closes the work.

Pigment Production under Cold Stress in the Green Microalga Chlamydomonas reinhardtii

Microalgae have long been used for the commercial production of natural colorants such as carotenoids and chlorophyll. Due to the rising demand for carotenoids and other natural products from microalgae, strategies to increase production efficiency are urgently needed. The production of microalgal biorefineries has been limited to countries with moderate climates. For countries with cooler climates and less daylight, methodologies for the efficient production of microalgal biorefineries need to be investigated. Algal strains that can be safely consumed as whole cells are also attractive alternatives for developing as carotenoid supplements, which can also contain other compounds with health benefits. Using such strains helps to eliminate the need for hazardous solvents for extraction and several other complicated steps. In this study, the mesophilic green alga Chlamydomonas reinhardtii was employed to study the effects of cold stress on cell physiology and the production of pigments and storage compounds. The results showed that temperatures between 10 and 20 °C induced carotenoid and chlorophyll accumulation in the wild-type strain of C. reinhardtii. Interestingly, the increased level of carotenoids suggested that they might play a crucial role in cold stress acclimation. A temperature of 15 °C resulted in the highest carotenoid and chlorophyll productivity. At this temperature, carotenoid and chlorophyll productivity was 2 times and 1.3 times higher than at 25 °C, respectively. Subjecting a mutant defective in lutein and zeaxanthin accumulation to cold stress revealed that these two carotenoids are not essential for cold stress survival. Therefore, cold temperature could be used as a strategy to induce and increase the productivity of pigments in C. reinhardtii.
Exploring the Influence of Multidimensional Tourist Satisfaction on Preferences for Wetland Ecotourism: a Case Study in Zhalong National Nature Reserve, China

Tourist satisfaction, as a principal element for sustainable development of wetland ecotourism and destination competitiveness, has received extensive attention in the research on its impact on behavioral intention. This paper employs choice experiment to study tourist satisfaction as an important motivation for behavioral intention of willingness to pay and preference on wetland ecotourism improvement policy, and explores the potential causal mechanism. A 15-item scale is designed to measure tourist satisfaction and four constructs are defined. Under the framework of discrete choice modeling, unidimensional and multidimensional data are incorporated as the standard for population segmentation and explanatory variables. The empirical results estimated by three methods basically confirms the proposed hypotheses and indicate that tourist satisfaction has a certain effect on tourist preference of wetland ecotourism and there is significant preference heterogeneity among groups with different satisfaction. Besides, different dimensions of satisfaction have a different effect on tourist preference of wetland ecotourism. This study enriches the studies on non-market value evaluation and preference motivation in the field of ecotourism, because tourist satisfaction may explain some unobserved preference heterogeneity. More effective wetland ecotourism policies can be designed when data on satisfaction are included.
Pengaruh transaksional elit politik terhadap model komunikasi politik pilwalkot Serang 2018

Transformasi sistem sentralistik menjadi disentralistik adalah hasil perjuangan reformasi yang berdampak sangat besar bagi perubahan sistem pemerintahan yang ada di Indonesia. Ruang demokrasi lokal kemudian menjadi menarik untuk diikuti karena dinamika kontestasi politiknya semakin hidup melalui jalur partai politik tetapi juga menciptakan model kepemimpinan transaksional. Kekuatan modal telah berperan di setiap tahapan proses kontestasi. Tujuan dalam penelitian ini adalah untuk melihat bagaimana pengaruh transaksional elit politik terhadap model komunikasi politik dalam Pilwalkot Serang tahun 2018, dimana fokus perhatian pada penelitian ini tentunya melihat bagaimana proses demokrasi ini terbebas dari praktek-praktek transaksional yang dapat berpengaruh pada arah penurunan substansial demokrasi itu sendiri. Pendekatan penelitian ini menggunakan perspektif post-positivistik menggabungkan pada pendekatan kuantitatif dan kualitatif yang mengolah data berdarsarkan pada jumlah sampel yang telah ditentukan pada populasi yang ada. Analisis data dari hasil angket yang disebarluaskan pada sampel kemudian dilakukan analisis dengan menggunakan path analisis menjelaskan Komunikasi Politik merupakan faktor yang cukup penting dan memiliki peran yang signifikan Sedangkan ideologi partai politik memberikan gambaran yang sangat signifikan. Artinya ketika ideologi partai bersumber pada finansial, maka semuanya akan tergantung pada janji dan nilai transaksi politik yang diandalkan. Hasil Penelitian menunjukkan korelasi antara Komunikasi politik uang terhadap transaksional politik terbilang cukup kuat, artinya komunikasi Politik memiliki korelasi yang cukup tinggi terhadap transaksional politik. Demikian pula Korelasi Ideologi terhadap transaksional politik adalah kuat artinya parpol tidak memiliki kekuatan dan idealisme ketika berbenturan dengan dana atau kekuatan finansial. Sedangkan korelasi antara Komunikasi Politik, Ideologi, terhadap Transaksional Politik adalah kuat, artinya kekuatan transaksional yang dilakukan oleh para elit sudah sangat masif dan memiliki peran yang sangat kuat.
Investor Attention and Broad Market Index: Evidence from Indonesia Composite Index

This study examines the relationship between investor attention and the broad market index in the Indonesia Composite Index (IHSG). In today’s digital world, the search engine becomes the most important tool in looking for information. Google dominated the market share with 91.38% of people use it. This number supports the use of Google to observe the behavior of the market. Instead of using it in specific assets or securities that can limit the scope of investors, this study is interested in using it in broad market index. Using Granger Causality Test and Vector Autoregression (VAR), we find that increasing attention can increase return and reduce market volatility. On the other hand, there is an indication that investors in Indonesia are typically risk-averse investors.
Jab My Arm, Not My Morality: Perceived Moral Reproach as a Barrier to COVID-19 Vaccine Uptake

Vaccinating the public against COVID-19 is critical for pandemic recovery, yet a large proportion of people remain unwilling to get vaccinated. Beyond known factors like perceived vaccine safety or COVID-19 risk, an overlooked sentiment contributing to vaccine hesitancy may rest in moral cognition. Specifically, we theorize that a factor fueling hesitancy is perceived moral reproach: the feeling, among unvaccinated people, that vaccinated people are judging them as immoral. Through a highly powered, preregistered study of unvaccinated U.S. adults (total N = 846), we found that greater perceived moral reproach independently predicted stronger refusal to get vaccinated against COVID-19, over and above other relevant variables. Of 22 predictors tested, perceived moral reproach was the fifth strongest—stronger than perceived risk of COVID-19, underlying health conditions status, and trust in scientists. These findings suggest that considering the intersections of morality and upward social comparison may help to explain vaccine hesitancy.
An examination of discourse analytic methods in the context of mathematical group work

In recent decades, mathematics education scholarship has promoted a shift from traditional teaching and learning approaches to novel approaches that privilege peer-to-peer collaboration. To mobilize researchers towards advancing scholarship on collaborative learning, scholars need to understand the methodologies available to them for examining group work. In this study, I synthesize and critically examine discourse analytic methodologies for analyzing group work in mathematics. Using a systematic review methodology, an initial 576 articles were considered, and 31 articles met the inclusion criteria for analysis. Articles were separated according to their research foci and methodologies were synthesized and critically evaluated. The review provides researchers with methodological options for analyzing group discourse in mathematics.
Content Analysis of Social Media on Indonesia Vaccination Covid-19 Policy

The purpose of this study is to determine the types of social media platforms used by proponents and opponents of vaccination. This research employs a qualitative approach, analyzing social media hashtag data with Q-DAS (Qualitative Data Analysis Software) and Nvivo 12Plus. This study finds that: First, social media was used to spread both sides' narratives and content. Second, social media relation tends to be quite strong, but the pro-side is stronger than the contra-side. Third, the narration on both sides uses hashtags and a single word to spread the influence. They were used for vaccination issues on two sides of the issue. This research limitation, like this study concentrating exclusively on social media data, excluded digital data like the phenomenon on social media only. The recommendation for the following research is: Try to understand the social movements opposing or promoting vaccination in Indonesia and compare them to other Asian countries. Keywords: vaccine; policy; social media.
Rental discrimination, perceived threat and public attitudes towards immigration and refugees

ABSTRACT There is still little research about the association of anti-immigrant attitudes with ethnic discrimination. In this study we investigate whether there is more rental discrimination against ethnic minorities in Belgian municipalities with more negative attitudes and higher perceived threats toward immigration and refugees. For this purpose, we merged unique data from correspondence tests with the aggregated attitudes in 44 municipalities. There was profound discrimination against candidates with Moroccan names by both private landlords and realtors. In contrast to theoretical expectations there was not more ethnic discrimination in municipalities with more negative attitudes or higher perceived threats. However, it appears that rental candidates – irrespective of their ethnic origin – are less likely to be invited in municipalities with higher threats and more negative attitudes.
