The aim of this study was to examine two types of time lag related to IT innovations in Japan. The first is the time lag between newspaper articles and academic papers in the past. The second is the ongoing time lag with regard to the big data trend between the United States and Japan. This article explores a new analytical process based on two-dimensional maps proposed by Krinder et al. (2005) for visualizing and measuring time lags. After overviewing the big data trend in Japan, the author analyzed 2,910 newspaper articles and 550 academic papers published in Japan related to past innovations, as well as 734 newspaper articles from the United States and 173 from Japan related to the big data innovation. The results indicate that academic research for past trends lags business trends by 1-4 years. However, time lags in the big data trend could not be captured because of the difficulty predicting the point of inflection of S-shaped curves in an early stage of innovation. Accordingly, the author simulated future S-shaped curves to show the gap between the United States and Japan.

<p><b>As the leading internet-distributed television platform (IDTVP) today, with over 200 millionworldwide subscribers, Netflix is a fascinating case-study through which to unpack thestrategies, innovations, and possibilities of internet-delivered television.</b></p> <p>This thesis argues that Netflix appropriates existing broadcast and premium cable networkpractices to produce original programming while using internet-originated tools, such as bigdata and algorithms, to continuously improve its interface design.

Abstract Objective Evidence has shown that Google searches for clinical symptom keywords correlates with the number of new weekly patients with COVID-19. This multinational study assessed whether demand for SARS-CoV-2 tests could also be predicted by Google searches for key COVID-19 symptoms. Methods The weekly number of SARS-CoV-2 tests performed in Italy and the United States was retrieved from official sources. A concomitant electronic search was performed in Google Trends, using terms for key COVID-19 symptoms. Results The model that provided the highest coefficient of determination for the United States (R2 = 82.8%) included a combination of searching for cough (with a time lag of 2 weeks), fever (with a time lag of 2 weeks), and headache (with a time lag of 3 weeks; the time lag refers to the amount of time between when a search was conducted and when a test was administered). In Italy, headache provided the model with the highest adjusted R2 (86.8%), with time lags of both 1 and 2 weeks. Conclusion Weekly monitoring of Google Trends scores for nonspecific COVID-19 symptoms is a reliable approach for anticipating SARS-CoV-2 testing demands ~2 weeks in the future.

The purpose of this study was to identify the social phenomena of tattoo, which have been of constant interest in our society, through analysis of social networks collected from big data on what the social phenomena implied in keywords emphasized in newspaper articles over the past year. To this end, by analyzing keywords about tattoos that frequently appeared in newspaper articles, we could see what the main interests of social phenomena related to tattoos were. Data on tattoos were collected from newspaper articles over the past year and analyzed how they formed meaning regarding the relationship structure and centrality between the keywords at issue through social network analysis. These findings provide basic data on social discussions and policy directions related to tattoos in practice and discussions related to ways to improve them. This study is an extension from existing quantitative research by analyzing the social phenomena of tattoos through Bigdata and social network analysis. Apart from statistical surveys or subjective qualitative research, we have approached them with content analysis using big data and social network analysis. The conclusion of this study is as follows. First, as a result of analyzing the word cloud regarding tattoos, it was confirmed that “rose” and “300” were the most prominent, and there were keywords that could analyze various other social phenomena. Second, as a result of analysis by connection centrality, it was proved that the social interest and popularity of tattoos increased. Third, as a result of analysis by eigenvector centrality, the popularity of tattoos was proved. It objectified academic research by attempting research from a different perspective from the analysis of research trends and provided visualized research results of readers.

Abstract A geostatistical framework for quantifying the temporal evolution and predictability of rainfall fields for time lags between 5 min and 3 h is proposed. The method is based on the computation of experimental space–time variogram maps of radar reflectivity fields. Two new metrics for quantifying temporal innovation and predictability based on minimum semivariance values at different time lags are proposed. The method is applied to high-resolution composite radar reflectivity maps over the United States to study the evolution of 25 convective and 25 stratiform events during the warm season of 2014. Results show that the temporal innovation can be modeled as the sum of two exponential functions of time lag, with approximately 50% of the total innovation occurring over the first 60 min. The median predictable scales for convective events are on the order of 1.6 km at 5 min, 5 km at 15 min, and 12.7 km at 1 h. Furthermore, the optimal time lag for predicting future innovation, taking into account measurement uncertainty and natural variability, appears to be between 30 and 60 min.

The number of public bikeshare systems has been increasing rapidly across the United States over the past 5 to 10 years. To date, most academic research around bikeshare systems in the United States has focused on the logistics of planning and operationalizing successful systems. Investigations of system users and effects on the local community are less common, and studies that are focused on efforts to engage underserved communities in bikeshare systems are rarer still. This paper relies on a survey of representatives from 56 U.S. bikeshare systems to better understand and document current approaches toward serving low-income and minority populations. The survey asked about equity policies and metrics, the degree to which equity considerations affect a variety of system practices, what the existing barriers to utilizing bikeshare are for target populations, and what challenges the bikeshare system entity faces in addressing those barriers. Results indicate that nearly one in four bikeshare systems has written policies around equity; nearly half of bikeshare systems with more than 500 bikes have such policies. However, many more systems consider equity in various aspects of their systems. Equity considerations affected station siting, fee structure and payment systems, and promotion and marketing in a majority of systems (68%, 72%, and 57%, respectively), and operations and data collection and analysis, though to a lesser extent (42% each). Bikeshare systems reported cost, access, and outreach as the largest barriers to equity, in addition to overall funding and staff levels.

1522 Background: Ideally, screening detects cancer at a more curable stage, and as a result decreases the incidence of subsequent diagnosis at a late stage. Whereas breast cancer screening is suggested to have led to a substantial increase in the number of early-stage cancers diagnosed in the United States with only marginal reductions in the number of late stage cancers, the impact of colorectal cancer screening on cancer incidence is unknown. Methods: Colorectal cancer incidence data spanning over three decades, 1976—2009, were collected from the Surveillance, Epidemiology, and End Result (SEER) database. Screening utilization data spanning 1986—2010 were collected from the National Health Survey (NHS) progress reports. We examined trends in the incidence of early-stage (in situ, local) and late-stage (regional, distant) colorectal cancer among adults 50 years or older. Results: Over the past three decades, the incidence of late-stage colorectal cancer decreased significantly, from 118 to 74 cases per 100,000 people—a 37% decrease. The incidence of early-stage colorectal cancer also decreased, from 77 to 67 cases per 100,000 people. There was also an associated increase in the utilization rates of screening colonoscopy. From 1987 to 2010—the years for which NHS data were available—the percentage of adults 50 and older who received screening colonoscopy rose from 27% to 63%. After adjusting for trends in cancer incidence in non-screened populations, we estimated that colorectal screening was associated with a reduction of approximately 550,000 cases of colorectal cancer over the past three decades in the United States. Using the most conservative assumption of constant cancer incidence during the past three decades, 235,000 cases of colorectal cancer were prevented. Conclusions: There has been a significant decline in both early and late stage colorectal cancer diagnoses, during a time of increasing rates of increased screening.

The authors in this article first identify the extent to which research articles published in three American Speech-Language-Hearing Association (ASHA) journals included participants, age birth to 18 years, from international backgrounds (i.e., residence outside of the United States), and go on to describe associated publication patterns over the past 12 years. These patterns then provide a context for examining variation in the conceptualization of ethnicity on an international scale. Further, the authors examine terminology and categories used by 11 countries where research participants resided. Each country uses a unique classification system. Thus, it can be expected that descriptions of the ethnic characteristics of international participants involved in research published in ASHA journal articles will widely vary.

Abstract. Background: In recent years, the rate of death by suicide has been increasing disproportionately among females and young adults in the United States. Presumably this trend has been mirrored by the proportion of individuals with suicidal ideation who attempted suicide. Aim: We aimed to investigate whether the proportion of individuals in the United States with suicidal ideation who attempted suicide differed by age and/or sex, and whether this proportion has increased over time. Method: Individual-level data from the National Survey on Drug Use and Health (NSDUH), 2008–2017, were used to estimate the year-, age category-, and sex-specific proportion of individuals with past-year suicidal ideation who attempted suicide. We then determined whether this proportion differed by age category, sex, and across years using random-effects meta-regression. Overall, age category- and sex-specific proportions across survey years were estimated using random-effects meta-analyses. Results: Although the proportion was found to be significantly higher among females and those aged 18–25 years, it had not significantly increased over the past 10 years. Limitations: Data were self-reported and restricted to past-year suicidal ideation and suicide attempts. Conclusion: The increase in the death by suicide rate in the United States over the past 10 years was not mirrored by the proportion of individuals with past-year suicidal ideation who attempted suicide during this period.

Japan and the United States, the world’s largest economies for most of the past half century, have very different immigration policies. Japan is the G7 economy most closed to immigrants, while the United States is the large economy most open to immigrants. Both Japan and the United States are debating how immigrants are and can con-tribute to the competitiveness of their economies in the 21st centuries. The papers in this special issue review the employment of and impacts of immigrants in some of the key sectors of the Japanese and US economies, including agriculture, health care, science and engineering, and construction and manufacturing. For example, in Japanese agriculture migrant trainees are a fixed cost to farmers during the three years they are in Japan, while US farmers who hire mostly unauthorized migrants hire and lay off workers as needed, making labour a variable cost.
