Abstract Half-hourly GPS zenith tropospheric delay (ZTD) and collocated surface weather observations of pressure, temperature, and relative humidity are available in near–real time from the NOAA Global Systems Division (GSD) research GPS receiver network. These observations, located primarily over the continental United States, are assimilated in a research version of the Environment Canada (EC) regional (North America) analysis and forecast system. The impact of the assimilation on regional analyses and 0–48-h forecasts is evaluated for two periods: summer 2004 and winter 2004/05. Forecasts are verified against radiosonde, rain gauge, and NOAA GPS network observations. The impacts of GPS ZTD and collocated surface weather observations for the summer period are generally positive, and include reductions in forecast errors for precipitable water, surface pressure, and geopotential height. It is shown that the ZTD data are primarily responsible for these forecast error reductions. The impact on precipitation forecasts is mixed, but more positive than negative, especially for the central U.S. region and for forecasts of larger precipitation amounts. Assimilation of the collocated surface weather data with ZTD contributes to the positive impact on precipitation forecasts for the central U.S. region. The NOAA GPS network data also have a positive impact on tropical storm system forecasts over the southeast United States, in terms of both storm track and precipitation. Impacts for the winter case are generally smaller because of the lower precipitable water (PW) over North America, but some positive impacts are observed for precipitation forecasts. The greatest regional impacts in the winter case are observed for the southeast U.S. (the Gulf) region where average PW is highest.

Pentecostalism as a new wave of Christianity became more pronounced in 1970's and beyond in Nigeria. Since then scholars of Religion, History, Sociology and Political Science have shown keen interest in the study of the Churches known as Pentecostals because of the impact they have made on the society. The Redeemed Christian Church of God (RCCG) was established by Pastor Josiah Akindayomi in Lagos,Nigeria in 1952. After his demise, he was succeeded by Pastor Adeboye Adejare Enock. The problem of study of this research was an examination of the expansion of the Redeemed Christian Church of God to North America, Caribbean and Canada. The missionary activities of the church could be regarded as a reversed mission in the propagation of Christianity by Africans in the Diaspora. The methodology adopted was historical. The primary and secondary sources of information were also germane in the research. The findings of the research indicated that the Redeemed Christian Church of God was founded in North America by Immigrants from Nigeria. Pastor Adeboye Enock Adejare had much influence on the Church within and outside the country because of his charisma. The Church has become a place of refuge for many immigrants. They are also contributing to the economy of the United States of America. However, the members of the Church were faced with some challenges, such as security scrutiny by the security agencies. In conclusion, the RCCGNA was a denomination that had been accepted and embraced by Nigerians and African immigrants in the United States of America.

Purpose: We aimed to study the impact of a combined faculty-student book club on education and medical practice as a part of the informal curriculum at the University of Florida College of Medicine in the United States.Methods: Sixteen medical students and 7 faculties who participated in the book club were interviewed through phone and recorded. The interview was then transcribed and entered into the qualitative data analysis program QSR NVivo (QSR International, Burlington, MA, USA). The transcripts were reviewed, and thematic codes were developed inductively through collaborative iteration. Based on these preliminary codes, a coding dictionary was developed and applied to all interviews within QSR Nvivo to identify themes.Results: Four main themes were identified from interviews: The first theme, the importance of literature to the development and maintenance of empathy and perspective-taking, and the second theme, the importance of the book club in promoting mentorship, personal relationships and professional development, were important to both student and faculty participants. The third and fourth themes, the need for the book club as a tool for self-care and the book club serving as a reminder about the world outside of school were discussed by student book club members.Conclusion: Our study demonstrated that an informal book club has a significant positive impact on self-care, perspective-taking, empathy, and developing a “world outside of school” for medical school students and faculty in the United States. It also helps to foster meaningful relationships between students and faculty.

This study examines how the use of different types of social media, such as Facebook and Twitter, affects public participation, drawing on the theory of motivation, which addresses the effect of internal and external political efficacy as well as the perceived political importance of social media. The study also investigates the interaction effect between social media use and perceived the political importance of social media on public participation. Employing a comparative perspective on an issue that has not been well studied, the study further seeks to discover potential variations in the impacts of different social media on public participation in the United States and Korea, both of which held presidential elections at the end of 2012. This study conducted hierarchical multiple regression analyses using data collected from college students in the United States and Korea. It shows the positive impact of social media use and its interaction effect with the perceived political importance of social media on the offline and online public participation of youth. The political motivational factor is found to be critical to driving public participation. This study also shows that the impact of Facebook use is more influential than Twitter use on public participation in the United States, whereas the opposite pattern is observed in Korea.

Abstract This paper verifies extratropical cyclones around North America and the adjacent oceans within the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) and North American Mesoscale (NAM) models during the 2002–07 cool seasons (October–March). The analyzed cyclones in the Global Forecast System (GFS) model, North American Mesoscale (NAM) model, and the North American Regional Reanalysis (NARR) were also compared against sea level pressure (SLP) observations around extratropical cyclones. The GFS analysis of SLP was clearly superior to the NAM and NARR analyses. The analyzed cyclone pressures in the NAM improved in 2006–07 when its data assimilation was switched to the Gridpoint Statistical Interpolation (GSI). The NCEP GFS has more skillful cyclone intensity and position forecasts than the NAM over the continental United States and adjacent oceans, especially over the eastern Pacific, where the NAM has a large positive (underdeepening) bias in cyclone central pressure. For the short-term (0–60 h) forecasts, the GFS and NAM cyclone errors over the eastern Pacific are larger than the other regions to the east. There are relatively large biases in cyclone position for both models, which vary spatially around North America. The eastern Pacific has four to eight cyclone events per year on average, with errors >10 mb at hour 48 in the GFS; this number has not decreased in recent years. There has been little improvement in the 0–2-day cyclone forecasts during the past 5 yr over the eastern United States, while there has been a relatively large improvement in the cyclone pressure predictions over the eastern Pacific in the NAM.

Abstract The following works are an exploration of the histories of colonization that the Mestizo experience in North America as well as how the settler colonial phenomenon continues to exist in the contemporary United States. The projects scrutinize the impact of racism, transphobia, classism, capitalism, and heteropatriarchy, as they affect the material realities of people whose lives are determined by their relationship to Western ideology and the gender construct. The use of sculpture, photography, and craft within the bodies of work help conceptualize the tension of Indigenous and Western narratives. Vick Quezada seeks to reconcile and intervene in Western “commonsense” notions by merging material culture by way of abstraction. Quezada is most compelled by the places where evidence of resistance and survival is made manifest. Through their work they desire to generate alternative empathies that open paths for a new consciousness.

The Impact

The projected changes in the downward solar radiation at the surface over North America for late 21st century are deduced from global climate model simulations with greenhouse-gas (GHG) forcing. A robust trend is found in winter over the United States, which exhibits a simple pattern of a decrease of sunlight over Northern USA. and an increase of sunlight over Southern USA. This structure was identified in both the seasonal mean and the mean climatology at different times of the day. It is broadly consistent with the known poleward shift of storm tracks in winter in climate model simulations with GHG forcing. The centennial trend of the downward shortwave radiation at the surface in Northern USA. is on the order of 10% of the climatological value for the January monthly mean, and slightly over 10% at the time when it is midday in the United States. This indicates a nonnegligible influence of the GHG forcing on solar energy in the long term. Nevertheless, when dividing the 10% by a century, in the near term, the impact of the GHG forcing is relatively minor such that the estimate of solar power potential using present-day climatology will remain useful in the coming decades.

This article focuses on cultural and creative activities and the development of local communities. Several studies on North America, Europe and Latin America have shown that this type of activity may have a positive impact on the local economy and living environments, and in particular on the sense of territorial belonging and on relations between citizens. In this text, we propose a reading of the impact of neighborhood cultural initiatives in the context of local socio-economic development based on a set of indicators of the local cultural vitality of a neighborhood. The empirical research was carried out in Montreal, namely on two boroughs: Rosemont–La Petite-Patrie and Sud-Ouest.

The article looks over the degree of implementation of FinTech services in the world. It’s determined that the leading countries in the implementation of FinTech are China, India, and South Africa. Crucial influencing factor is demographic, rather than the widespread demand among the population for modern technology. The penetration rate of these services in the United States, where the largest technology companies in the world are located, was only 46%. The share of service users among the population that actively use digital technologies reaches 33%. Noted that the objects of investment of American banks are startups, programming applications of open interfaces and platforms for third-party developers. European banks also aim to invest actively in the development of FinTech but are still more focus on their own development. It is determined that Asian, Australian and African banks tend to develop technological solutions on their own. According to experts, the number of partnership agreements in the world with FinTech companies will increase each year. The analysis of the regional structure of global investments in FinTech carried out. It showed a positive dynamics of investment during 2014–2019. Increasing the size of global investments is due to the interest of investors in new projects and business models. Venture capital investment priorities coincide with global ones and are related to reviewing, updating, and improving business processes. The amount of venture capital invested in FinTech projects stimulates the development of the financial industry, mainly in China, the United States, the United Kingdom, and Ireland. They account for almost 9 times more investment in FinTech than in other countries. Correlation-regression analysis was applied to investigate the relationship between the level of development of the FinTech market and foreign direct investments. According to the results of calculations, the largest impact on foreign direct investment has the volume of venture investment in FinTech-projects and the FinTech market development rating. This proves the positive impact of FinTech companies on the growth of foreign investments in the country.

The Impact

Reconstructing the geographic origins of invasive species is critical for establishing effective management strategies. Frequently, molecular investigations are undertaken when the source population is not known, however; these analyses are constrained both by the amount of diversity present in the native region and by changes in the genetic background of the invading population following bottlenecks and/or hybridization events. Here we explore the geographical origins of the invasive winter moth (Operopthera brumata L.) that has caused widespread defoliation to forests, orchards, and crops in four discrete regions: Nova Scotia, British Columbia, Oregon, and the northeastern United States. It is not known whether these represent independent introductions to North America, or “stepping stone” spread among regions. Using a combination of Bayesian assignment and approximate Bayesian computation methods, we analyzed a population genetic dataset of 24 polymorphic microsatellite loci. We estimate that winter moth was introduced to North America on at least four occasions, with the Nova Scotian and British Columbian populations likely being introduced from France and Sweden, respectively; the Oregonian population likely being introduced from either the British Isles or northern Fennoscandia; and the population in the northeastern United States likely being introduced from somewhere in Central Europe. To our surprise, we found that hybridization has not played a large role in the establishment of winter moth populations even though previous reports have documented widespread hybridization between winter moth and a native congener. We discuss the impact of genetic bottlenecks on analyses meant to determine region of origin.
