Published: February 2021

Background
Rapid eye movement sleep behavior disorder (RBD) and olfactory dysfunction are useful for early diagnosis of Parkinson’s disease (PD). RBD and severe olfactory dysfunction are also regarded as risk factors for cognitive impairment in PD. This study aimed to assess the associations between RBD, olfactory function, and clinical symptoms in patients with PD.

Methods
The participants were 404 patients with non-demented PD. Probable RBD (pRBD) was determined using the Japanese version of the RBD screening questionnaire (RBDSQ-J) and the RBD Single-Question Screen (RBD1Q). Olfactory function was evaluated using the odor identification test for Japanese. Clinical symptoms were evaluated using the Movement Disorder Society Revision of the Unified PD Rating Scale (MDS-UPDRS) parts I–IV.

Results
In total, 134 (33.2%) patients indicated a history of pRBD as determined by the RBD1Q and 136 (33.7%) by the RBDSQ-J based on a cutoff value of 6 points. Moreover, 101 patients were diagnosed as pRBD by both questionnaires, 35 by the RBDSQ-J only, and 33 by the RBD1Q only. The MDS-UPDRS parts I–III scores were significantly higher and disease duration significantly longer in the pRBD group. pRBD was significantly associated with male gender and the MDS-UPDRS part I score. The olfactory identification function was significantly reduced in the pRBD group.

Conclusions
About 33% of the patients with PD had pRBD based on the questionnaires, and both motor and non-motor functions were significantly decreased in these patients. These results suggest that more extensive degeneration occurred in patients with non-demented PD with RBD.

Introduction
Adverse birth outcomes have important consequences for future lung health. We evaluated patterns of respiratory health services utilization in early childhood among children born preterm (PTB), small and large for gestational age at term (SGA and LGA, respectively), and appropriate-for-gestational age at term.

Materials and methods
We conducted a population-based retrospective cohort study using administrative health data of all singleton live births in Alberta, Canada between 2005–2010. Data on hospitalizations and emergency department (ED) visits from birth to 5 years were collected for asthma, bronchitis, bronchiolitis, croup, influenza, pneumonia, and other acute upper and lower respiratory tract infections (other URTI and other LRTI, respectively). Adjusted rate ratios were estimated for respiratory ED visits and hospitalizations for adverse birth outcomes using the appropriate-for-gestational age at term group as reference. Age-specific trajectories of total respiratory health services utilization rates for each group were estimated in Poisson models.

Results
A total of 293,764 episodes of respiratory care from 206,994 children were analyzed. Very PTB children had the highest rates of health services use for all respiratory conditions, particularly for asthma, pneumonia, and bronchiolitis hospitalizations. Moderate/late PTB children also had elevated ED visits and hospitalizations for all respiratory conditions. Children born SGA showed high rates of ED visits for other LRTI, and of hospitalizations for bronchitis, bronchiolitis, and other URTI. Children born LGA had high rates of croup and other URTI ED visits, and of bronchiolitis and bronchiolitis hospitalizations. Age-specific trajectories showed a decreasing trend in the rates of total respiratory health service utilization from birth to five years of age for all groups studied. Children born PTB and LGA at term significantly required more respiratory health services over time compared to the reference group.

Conclusion
Patterns of paediatric respiratory health services utilization vary according to gestational age and fetal growth.

Unraveling News: Reconciling Conflicting Evidence
Authors: Bolboaca Maria , Fischer Sarah 
Published: February 2021

Abstract
This paper addresses the lack of consensus in the empirical literature regarding the effects of technology diffusion news shocks. We attribute the conflicting evidence to the wide diversity in terms of variable settings, productivity series used, and identification schemes applied. We analyze the different identification schemes that have been employed in this literature. More specifically, we impose short- and medium-run restrictions to identify a news shock. The focus is on the medium-run identification maximizing at and over different horizons. We show that the identified news shock depends critically on the applied identification scheme and on the maximization horizon. We also investigate the importance of the information content of the model and of the productivity measure used. We find that models which either contain a large set of macroeconomic variables or include variables that are strongly forward looking deliver more robust results. Moreover, we show that the productivity series used may influence results, but there is convergence of findings for newer total factor productivity series vintages. Our conclusion is that news shocks have expansionary properties.
Agricultural Trade and Structural Change: Evidence from Paraguay
Authors: Blanco Cesar 
Published: February 2021

Abstract
We study how international trade affects structural change in an agricultural exporting country. For this purpose, we calibrate a three-sector growth model to quantify the role of international trade in explaining structural change patterns observed in Paraguay. This country experienced a significant rise in net agricultural exports as a percentage of aggregate output during the period 1962–2012. We find the following results. First, international trade is crucial to explain the sectoral composition of employment in this country. The model including trade explains 84.2% of observed changes in employment shares during this period, while the model without trade can only account for 35.6% of observed changes. Second, employment in agriculture remains large in order to satisfy foreign demand. Third, employment shifts directly from agriculture into services in the long run, bypassing manufacturing. These patterns can only be explained by the rise in net agricultural exports.

Abstract
The purpose of this study was to assess the relationship between 25-hydroxyvitamin D (25(OH)D), urinary iodine concentration (UIC), and type 2 diabetes mellitus (T2DM) risk and complications and to establish a model to predict T2DM in the general population. A total of 567 adults (389 T2DM patients and 178 controls) were enrolled, and the levels of 25(OH)D, iodine, and blood biochemical parameters were measured. Pearson’s correlation analysis showed an inverse correlation between 25(OH)D level, UIC, and T2DM risk. Low 25(OH)D level was a risk factor for developing T2DM (OR, 0.81; 95% CI, 1.90–2.63; P = 0.043) after adjustment for multiple risk factors. 25(OH)D level and UIC were inversely correlated with short-term and long-term glucose levels. 25(OH)D deficiency was also associated with a high incidence of T2DM complicated with thyroid dysfunction. A prediction model based on 25(OH)D, iodine status, and other risk factors was established and recommended to screen high-risk T2DM in the general population and provide early screening and timely treatment for them.

Published: February 2021

Abstract
Since the 2016 election, the relationship between Trump supporters and Fox News has gained considerable attention. Drawing on interviews with more than 200 people and a representative survey conducted in the state of Wisconsin, we dive deeper into the media habits of Trump supporters using a mixed methods analytical approach. While we do not refute the importance of Fox News in the conservative media ecology, we find that characterizing Trump supporters as isolated in Fox News bubbles obscures the fact that many are news omnivores, or people who consume a wide variety of news. In fact, we find that Trump supporters may have more politically heterogeneous consumption habits than Trump non-supporters. We find that 17% of our survey respondents who support Trump in Wisconsin are regularly exposed to ideologically heterogeneous news media. We also find that like other voters, Trump supporters are disenchanted with the divisive nature of contemporary media and politics. Finally, we analyze the media use of young Trump supporters and find an especially high level of news omnivorousness among them.
Marching to the Ballot Box: Sex and Voting in the 2020 Election Cycle
Authors: Ondercin Heather L. 
Published: February 2021

AbstractWith the 2020 election marking the 100th anniversary of the ratification of the 19th Amendment, our attention has been keenly focused on women voters. Media coverage of women voters portrayed them as swing voters and focused on a small subgroup of women (white, married, mothers). I argue that women’s and men’s voting behavior in 2020 was highly similar to past elections and does not support the claims that women or a subgroup of women are swing voters. I illustrate the diversity of women’s voting behavior through analyzing the intersection of gender with race, ethnicity, education, marital status, and parental status. Even though women were not swing voters, women still play an important role in electoral politics, representing the majority of members in both the Democratic and Republican Parties and holding stronger attachments to these parties than men.

The timing of Barleik Formation and its implication for the Devonian tectonic evolution of Western Junggar, NW China
Authors: Hui Yuanxiu , Wang Ran , Li Lu , Lin Jingyu , Xiao Zhouxuan , Xin Yonghui , Luo Xin 
Published: February 2021

Abstract
The timing of Barleik Formation in Xinjiang, NW China, has not been constrained by accurate geochronology yet, while this work is of great significance to help reconstruct the geological tectonic evolution of Western Junggar. Based on the LA-ICP-MS U–Pb geochronology study, the weighted average age of magmatic zircons collected from the tuff in Barleik Formation, which reflects the formation age of the tuff, is 372 ± 2 Ma (N = 57, mean square of weighted deviates (MSWD) = 1.15). The first report in this study of the zircon U–Pb dating result indicates that Barleik Formation along the West Junggar tectonic belt occurred in the Late Devonian rather than in the middle Devonian period as previously claimed. Meanwhile, chronology data and the geochemical features comparing with the Island Arc-related rocks in the adjacent area, as well as stratigraphic structural relationship, suggest that volcanic activities may exist in the Late Devonian, and the relevant volcanic ash deposited in the Barleik forearc basin may be derived from the adjacent island arc (current geographic coordinate). In addition, the fossil assemblage dominated by bathyal-abyssal invertebrate fossils and bathyal-abyssal facies indicates that the Barleik Formation is a bathyal-abyssal sedimentary environment.
Comparative Law and EU Legal Language: Towards a European Restatement?
Authors: Ioriatti Elena 
Published: February 2021

AbstractDespite the ongoing developments in comparative law studies, European legal language is still in want of responses with regard to its own characteristics and impact in the Member States. This article suggests an interdisciplinary perspective, that of comparative law and semiotics, as well as the observation of the normative forces grounding the practices of EU law in the Member States. As a dialogical conclusion, a Restatement will be suggested, where EU concepts could be channeled. This intellectual tool could be relevant in legal education too and favor the institutional dialogue among national and European actors of the multilingual legal process.
Investigation of the microstructure evolution in TP347HFG austenitic steel at 700°C and its characterization method
Authors: Zhang Yuetao , Yuan Tingbi , Shao Yawei , Wang Xiao 
Published: February 2021

AbstractThis article reports the microstructure evolution in TP347HFG austenitic steel during the aging process. The experiments were carried out at 700°C with different aging time from 500 to 3,650 h. The metallographic results show that the coherent twin and incoherent twin are existed in the original TP347HFG grains, while they gradually vanished with the increase of the aging time. After aging for 500 h, a lot of fine, dispersed particles precipitated from the matrix, but they disappeared after aging for 1,500 h. When the aging time extend to 3,650 h, the precipitates appeared apparently coarse in TP347HFG steel, which include the M23C6andσphase; besides, the micro-hardness of TP347HFG also changes during the aging, which was closely related to the effect of dispersion strengthening and solution strengthening. The results of the nonlinear ultrasonic measurement reveal that theβ′ of TP347HFG steel was also changed with the aging time. It first increased at 0–500 h, then reduced later, and increased finally at 1,500–3,650 h. The variation ofβ′ in TP347HFG was influenced by a combined effect of the twin microstructure and the precipitate phase, which indicate that the nonlinear ultrasonic technique can be utilized to characterize the microstructure evolution in TP347HFG.
Fault location in the distribution network based on power system status estimation with smart meters data
Authors: Dashtdar Masoud , Sadegh Hosseinimoghadam Seyed Mohammad , Dashtdar Majid 
Published: February 2021

Abstract
Due to the existence of different branches in the electricity distribution network and only available voltage and current information at the beginning of the line and lack of access to the information at the end of the network line, the detection of the faulted section in the distribution network has become more important. Today, smart meters are used to measure the voltage and current of network lines, but due to the limitations of the installation sites, these devices are not possible in all network lines. In this paper, two techniques have been used to identify the faulted section and fault location in the network so that the fault distance at the beginning of the line can be estimated by estimating the current at the end of each network line. Therefore, in this project, by installing smart meters in the main branch of the network and also the information obtained from power flow in the network normal mode, it has been tried to practically estimate the voltage and current at the beginning and end of each distribution network line. In this method, more power flow is used to calculate the voltage drop of the lines and estimate the voltage and current at the end of the network lines so that the faulted part can be identified. Finally, the proposed method is implemented on the IEEE_15, 37 bus networks, the results of which show the proper performance of the proposed method in estimating location and Fault resistance for different types of faults in the distribution network.
An Improved Adaptive Weighted Mean Filtering Approach for Metallographic Image Processing
Authors: Shao Chonglei , Kaur Preet , Kumar Rajeev 
Published: February 2021

Abstract

Background
As noise brings great error in the analysis of metallographic images, an adaptive weighted mean filtering method proposed to overcome the shortcomings of the standard mean filtering method.

Methods
The method used to detect the pulse noise points in the image, and then the modified mean method used to filter out the detected noise points. Patents on metallographic image processing have discussed for the development of the proposed methodology.

Results
It is shown that filter window can be filtered in comparison with the conventional 3×3, 5×5 and 7×7 filt window to reduce noise detection and reduce the complexity of the weight calculation.

Conclusion
It can be concluded that this method can better protect the details of the image, has better filtering effect than the standard mean filtering, and its processing speed is faster than the median filtering of the large window, which has profound significance for the edge detection and processing of the metallographic image.
