UNSTRUCTURED The article, published on 23 July 2021, is well-written and of interest, but remains several questions that are required for clarifications, such as (1) the static choropleth map of collaboration analysis between countries should be dynamically visualized and highlighted by top three countries on their publications and author collaboration characteristics; (2) the research achievements in authors, institutes, and countries should be quantified by author-weighted scheme considering author order in article bylines; and (3) keyword analysis was too simple to identify the difference in article types between countries. We downloaded 2,268 abstracts from the Pubmed database with a search string of (COVID-19[MeSH Major Topic]) AND (pediatrics[Affiliation]), similar to the mentioned study, and displayed (1) choropleth maps highlighted by the most productive and highly author-collaborated countries, and (2)forest plot to identify differences in article types between two countries. The medical subject headings(MeSH terms) were used to denote the article types in articles. We observed that (1) three top productive countries were the United States, Italy, and India; (2) three top countries collaborated the authors affiliated with the US were Canada, the United Kingdom, and Italy; and (3) only the MeSH term of epidemiology presents the difference in article types between the US and India when the top 10 most frequently occurred MeSH terms were compared. We produced the dashboard-type visualizations to provide valuable information for readers. The novel visual representations make data clear with a better understanding of bibliographic analysis. The methods used in this study are recommended for future studies, not just limited to the field of COVID-19 research.

Abstract Background Citation analysis has been increasingly applied to assess the quantity and quality of scientific research in various fields worldwide. However, these analyses on spinal surgery do not provide visualization of results. This study aims (1) to evaluate the worldwide research citations and publications on spinal surgery and (2) to provide visual representations using Kano diagrams onto the research analysis for spinal surgeons and researchers. Methods Article abstracts published between 2007 and 2018 were downloaded from PubMed Central (PMC) in 5 journals, including Spine, European Spine Journal, The Spine Journal, Journal of Neurosurgery: Spine, and Journal of Spinal Disorders and Techniques. The article types, affiliated countries, authors, and Medical subject headings (MeSH terms) were analyzed by the number of article citations using x-index. Choropleth maps and Kano diagrams were applied to present these results. The trends of MeSH terms over the years were plotted and analyzed. Results A total of 18,808 publications were extracted from the PMC database, and 17,245 were affiliated to countries/areas. The 12-year impact factor for the five spine journals is 5.758. We observed that (1) the largest number of articles on spinal surgery was from North America (6417, 37.21%). Spine earns the highest x-index (= 82.96). Comparative Study has the highest x-index (= 66.74) among all article types. (2) The United States performed exceptionally in x-indexes (= 56.86 and 44.5) on both analyses done on the total 18,808 and the top 100 most cited articles, respectively. The most influential author whose x-index reaches 15.11 was Simon Dagenais from the US. (3) The most cited MeSH term with an x-index of 23.05 was surgery based on the top 100 most cited articles. The most cited article (PMID = 18164449) was written by Dagenais and his colleagues in 2008. The most productive author was Michael G. Fehlings, whose x-index and the author's impact factor are 13.57(= √(13.16*14)) and 9.86(= 331.57/33.64), respectively. Conclusions There was a rapidly increasing scientific productivity in the field of spinal surgery in the past 12 years. The US has extraordinary contributions to the publications. Furthermore, China and Japan have increasing numbers of publications on spinal surgery. This study with Kano diagrams provides an insight into the research for spinal surgeons and researchers.

BACKGROUND The citation trend of research has frequently been applied to topical entities of interest in bibliographical studies. Although the burst spot and the corresponding burst strength can be highlighted in the traditional temporal bar graph (TBG) as viewing their evolutions of entities, no such growth trends were added to the TBG for a better understanding of future tremd (e.g., reading to rise, increasing, decreasing, or slowdown). A step-by-step scheme for constructing the bibliographical study is thus required to make data meaningful and fruitful. OBJECTIVE This article assesses (1) whether an EISTL model (i.e., identifying the topical entity, indicator, selection of top entities, TBG, and using the line-chart plot for verification) can be applied to display the trend analysis of article citations for entities and (2) whether the TBG can be enhanced to release more valuable information for readers. METHODS We obtained 2,151 abstracts indexed in PubMed by searching the keywords “JMIR mHealth and uHealth” (Journal) on November 11, 2021. The metadata was collected, including author names, research institutes, article identifiers (PMIDs), countries, and medical subject headings (MeSH terms). The burst spot and the growth trend were displayed along with the inflection point (IP) using the Newton–Raphson Iteration Method (NRIM) and the growth/share matrix (GSM). Cooccurrence analysis was performed to select the top-cited entities using social network analysis (SNA) and Sankey diagrams. The TBG plays a transitive role before drawing the line-chart plot in the EISTL model. Both choropleth map and Kano diagram were used to compare and classify research achievements (RA) for countries using the x-index. The differences in RAs were compared between two groups (i.e., participants of Summit for Democracy (SFD) 2021 and Non-SFD) using the forest plot. All animation-typed dashboards were laid on Google Maps for readers to manipulate entities of interest on their own. RESULTS The burst spot and citation trend for the top entities were selected and displayed on the TBG. The most cited entities were sequentially shown in the Sankey diagram, including Stoyan R Stoyanov (Australia), Queensland University of Technology (Australia), PMID=25760773, the US, and standards (MeSH). The top three most cited counties/regions were highlighted in a choropleth map and Kano diagram using the x-index to stratify in descending order: Australia, the UK, and Canada with x-indexes of 23.26, 22.21, and 21.42, respectively, when the US and China were divided into individual states and provinces for comparison. Differences in the six selective bibliometric metrics were not found (p>0.05) in countries between SFDs and non-SFDs. CONCLUSIONS We verified that (1) the EISTL model is viable and useful for presenting citation trends in bibliometric research, and (2) the improved TBG mode releases more information about citation trends. The EISTL model makes the bibliometrics clearer and easier to understand. As a corollary, the TBG with citation trends and burst spots is recommended for future bibliometrics and is not merely limited to the citation trends of the JMIR mHealth and uHealth, as we did in this study.

The Kurdish Civil War between the military forces of the Kurdistan Democratic Party (KDP) and the Patriotic Union of Kurdistan (PUK) began in 1994. Despite frequently occurring peace talks throughout the conflict, negotiations failed to bring about a durable settlement until the United States brokered the Washington Peace Agreement in 1998. This research explores why the earlier negotiations were unsuccessful, and whether it was only the US mediation in 1998 which made the difference. Although the US mediation was clearly an important factor, by employing the contingency model this research argues that both contextual variables and process variables determined the success of negotiations in 1998. Furthermore, they can explain the failure of the previous 4 years of negotiations.

This paper estimates the net social wage—the difference between labor benefits and labor taxation—from 1959 to 2012 in the United States using two different methodologies. During this period the average NSW1/GDP and NSW2/GDP ratio are 1.3 and −3.8 percent, respectively. This paper finds a deviation in the net social wage data starting in 2002, suggesting greater redistribution to US workers in the early twenty-first century than in the twentieth century. This paper argues that the increase in the US net social wage in the early twenty-first century is being caused by a combination of cyclical, structural, and secular factors. US redistributive policy should be understood as stabilizing and subsidizing the social reproduction of labor. JEL Classification: H5, E62, B5

Abstract BACKGROUND In the United States, current guidelines recommend a total sodium intake <2,300 mg/day, a guideline which does not consider kilocalorie intake. However, kilocalorie intake varies substantially by age and sex. We hypothesized that compared with sodium density, total sodium intake overestimates adherence to sodium recommendations, especially in adults consuming fewer kilocalories. METHODS In the National Health and Nutrition Examination Survey (NHANES), we estimated the prevalence of adherence to sodium intake recommendations (<2,300 mg/day) and corresponding sodium density intake (<1.1 mg/kcal = 2,300 mg at 2,100 kcal) by sex, age, race/ethnicity, and kilocalorie level. Adherence estimates were compared between the 2005–2006 (n = 5,060) and 2015–2016 (n = 5,266) survey periods. RESULTS In 2005–2006, 23.1% (95% confidence interval [CI]: 21.5, 24.9) of the US population consumed <2,300 mg of sodium/day, but only 8.5% (CI: 7.6, 9.4) consumed <1.1 mg/kcal in sodium density. In 2015–2016, these figures were 20.9% (CI: 18.8, 23.2) and 5.1% (CI: 4.4, 6.0), respectively. In 2015–2016, compared with 2005–2006, adherence by sodium density decreased more substantially (odds ratio = 0.59; CI: 0.48, 0.72; P < 0.001) than adherence by total sodium consumption (odds ratio = 0.85; CI: 0.73, 0.98; P = 0.03). The difference in adherence between total sodium and sodium density goals was greater among those with lower kilocalorie intake, namely, older adults, women, and Hispanic adults. CONCLUSIONS Adherence estimated by sodium density is substantially less than adherence estimated by total sodium intake, especially among persons with lower kilocalorie intake. Further efforts to achieve population-wide reduction in sodium density intake are urgently needed.

Aims: We visualized the current state of research on publication outputs and citations in the field of medicine and health to uncover topic burst and citations among medical subject headings (MeSH) clusters. Study Design: A bibliometric analysis. Place and duration of Study: Using Pubmed indexed articles to inspect the characteristics of topics on medicine and health since 1969. Methodology: Selecting 156 abstracts, author names, countries, and MeSH terms on January 10, 2019, from Pubmed Central (PMC) based on the terms of medicine and health in the title since 1969, we applied the x-index and impact factor to evaluate author individual research achievements and compute MeSH bibliometric performances. The bootstrapping method was used to estimate the median and its 95% confidence intervals and make differences in metrics among MeSH clusters. The dominant nations were selected using the x-index to display on a dashboard. We programmed Microsoft Excel VBA routines to extract data. Google Maps and Pajek software were used for displaying graphical representations. Results: We found that (1)the dominant countries/areas are the Unlited States, Taiwan, and Australia; (2) the author Grajales, Francisco Jose 3rd form Canada has the most cited metrics such as author IF=39.46 and x-index=6.28; (3)the MeSH terms of organization & administration, standards, and prevention & control gain the top three degree centralities among MeSH clusters; (4) No any differences in metrics were found among MeSH clusters; (5) the article(PMID= 24518354) with three MeSH term of delivery of health care, social media, and software and published in 2014 was cited most at least 62 times. Conclusion: Social network analysis provides wide and deep insight into the relationships among MeSH terms. The MeSH weighted scheme and x-index were recommended to academics for computing MeSH citations in the future.

Abstract Abstract 2695 Background: Malignant lymphomas (ML) are heterogeneous groups that the detailed classification is evolving dramatically. An incidence of malignant disease in certain population reflects cumulative exposure to environment, genetics and their combination overtime. Therefore, a comparison of incidences in various population and their secular trends is very helpful to understand etiology of disease. The aim of this study is to assess the incidence and the trend of each ML subtypes and to evaluate the difference between Japan and US. Materials and Methods: We used the data from a population-based cancer registry in Japan and from the Surveillance Epidemiology and End Results (SEER) program 9. Registry data of the US, SEER 9 included 95,155 cases and the data of Japan included 48,658 cases. The period covered in this analyses was 1993 to 2006 in Japan and 1993 to 2008 in the US. Rates of sex-specific, age-standardized incidence with 95% confidence intervals were estimated and standardized by age-adjustment according to the world standard population. We also estimated the annual percent change using joinpoint regression analysis and evaluated the significance of the trend. Results: The overall age-standardized incidence rate of all malignant lymphomas per 100,000 in 2006 was 22.4 for males and 16.0 for females in the US, 7.4 for males and 4.9 for females in Japan. The incidence is higher in the US than Japan with most of the subtypes especially for the nodular sclerosis HL, CLL/SLL and FL. In general, B-cell lymphomas showed large difference in incidence while T-cell lymphomas (TCL) showed similar incidence between Japan and the US. The total numbers of ML are constantly increasing in Japan but not in the US as shown in the figure {annual percent change (95%CI), Japan; +2.6% (2.1, 3.1), US; +0.2% (−0.0, 0.4)}. As for details, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma and the total numbers of TCL are constantly increasing in both countries. Conclusion: In conclusion, we showed the marked difference in the incidence and the trend of hematologic malignancies between Japan and the US. The incidence of hematologic malignancies is lower in Japan than the US, but is increasing significantly. The most remarkable difference in the incidence was seen with nodular sclerosis HL, CLL/SLL and FL which was consistent with previous reports. Even with the TCL, the incidence seems to be similar to higher in the US except for the ATLL. The improvement in the quality of cancer registry systems and the organization of these registries between countries enables us to unite the data worldwide that will bring us new insights. Solid line and circle are the data of the US. Dashed line and hollow circle are the data of Japan. Disclosures: No relevant conflicts of interest to declare.

AbstractUsing data from the Multinational Time Use Study, this paper documents the trend and level of time allocation, with a focus on home hours, for the US and European countries. Three patterns emerge. First, home hours per person have declined in both the US and European countries over the past 50 years. Second, female time allocation contributes more to the difference in time allocation per person between the US and European countries than does male time allocation. Third, the time allocation between the US and European countries is more similar for prime-age individuals than for young and old individuals.

Abstrak Sejarah mencatat sentimen rasial yang tertuang dalam produk undang-undang Amerika Serikat seperti Chinese Exclusion Act 1882, pada masanya turut menyasar para imigran dan warga keturunan Jepang. Beragam tindakan kekerasan verbal maupun fisik dan diskriminasi dialami imigran Asia, dalam konteks ini Cina dan Jepang, ketika itu. Lebih lanjut, merebaknya Covid-19 dalam kurun dua tahun ini kembali memunculkan masalah sosial serupa bagi komunitas imigran dan warga keturunan Asia, termasuk Jepang. Isu berhembus memojokan para pendatang dan warga keturunan Asia sebagai tertuduh pembawa virus Covid-19. Dengan demikian, aksi-aksi rasis, diskriminatif, dan xenophobic terrekam pada dua konteks waktu yang berbeda. Dengan mengumpulkan data-data melalui metode studi pustaka dan kemudian mengolahnya, diketahui terdapat perbedaan dan kesamaan fenomena di tengah sentimen-sentimen yang menarget imigran maupun warga keturunan Jepang di Amerika. Perbedaan yang dimaksud merujuk pada aspek pemicu. Pada masa-masa awal kedatangannya, sentimen terhadap imigran Jepang di Amerika Serikat dipicu oleh masalah kesempatan kerja dan kecurigaan bernuansa politik. Sementara itu, pada kurun waktu pandemi Covid-19 sentimen anti-Asian dipicu oleh isu penyebaran virus Covid-19. Di sisi lain, terdapat kesamaan dalam munculnya sentimen-setimen anti-Asian dulu dan kini yaitu tersebarnya informasi palsu dan provokatif, merebaknya prasangka dan diskriminasi rasial, adanya peran tokoh publik dalam menyebarkan kebencian, dan adanya kebijakan hukum yang diambil oleh otoritas untuk merespon isu terkait.  Kata Kunci: Amerika Serikat, Jepang, Imigran, Xenophobia, Covid-19 AbstractChinese Exclusion Act of 1882, which was one of the US Federal Laws restricting immigration, was meant to target Chinese immigrants at that time. Being among the Asian communities in the US, the Japanese immigrants were unsurprisingly affected. Racial discrimination and hatred began to arise as the implementation of the law was going on. Various acts of verbal and physical violence suffered by the Asian (Chinese and Japanese) immigrants at that time. Further, the outbreak of Covid-19 in the past two years has raised similar social problems for the immigrant communities and people of Asian descent including Japanese. The issue of cornering the immigrants and the residents of this descent as being accused of carrying the Covid-19 virus arises. Various acts of hatred begin to target the immigrants and citizens of Asian descent. Applying the library research method and processing the relevant data, there found differences and similarities amidst the sentiments targeting the immigrants and citizens of Japanese descent in America. The difference refers to the triggering aspect. In the early days of their arrival, the anti-Japanese immigrant sentiment in the United States was more motivated by the problems of job opportunity and political suspicions. Meanwhile, during the Covid-19 pandemic, anti-Asian sentiment was triggered by the issue of the spread of the Covid-19 virus. On the other hand, there are similarities to the emergence of anti-Asian sentiments today including the spread of false and provocative information, the spread of racial prejudice and discrimination, the role of public figures in spreading hatred, and the existence of legal policies taken by authorities to respond to the related issues.  Keywords: the United States, Japanese, Immigrants, Xenophobia, Covid-19
