Identification of the Emerging C1-like Lineage of Enterovirus A71 in Two Uruguayan Children with Hand-Foot-and-Mouth Disease and Neurological Complications

Enterovirus A71 (EV-A71) is a major cause of hand-foot-and-mouth disease (HFMD), particularly in cases that involve complications affecting the nervous system or cardiopulmonary function. In South America, EV-A71 has primarily been identified through studies of acute flaccid paralysis (AFP) and other neurological disorders. In September 2022, two children from a small city in Uruguay were hospitalized with presumptive rhombencephalitis, exhibiting symptoms of HFMD. EV-A71 was identified through RT-PCR and next-generation sequencing of stool and skin lesion samples. A maximum-likelihood phylogenetic analysis of the P1 coding region classified the Uruguayan strains as part of an emerging lineage, primarily reported in Europe over the past decade, known as the C1-like lineage. The findings presented here represent the first detection of the EV-A71 C1-like lineage in cases of HFMD and encephalitis reported from South America, underscoring the urgent need to enhance surveillance for HFMD, aseptic meningitis, encephalitis, and AFP, in countries facing challenges in establishing effective surveillance programs related to enteroviruses and associated diseases.

Turkey’s higher education boom: the ‘one university in every city’ policy in small cities

ABSTRACT Over the past two decades, Turkey’s higher education system has undergone a massive and globally unprecedented transformation. Enrollment rates increased more than fivefold, driven by the government’s comprehensive policy of establishing ‘one university in every city.’ As a result, new universities were instituted in 41 small cities that previously lacked independent higher education infrastructure. The Justice and Development Party (AKP) governments framed this initiative as a key ideological distinction from their predecessors, emphasizing it as a cornerstone of their educational and social policy, particularly targeting small cities across the country as well as the country’s youth. While the ideological divergence between the AKP and prior governments played a critical role in justifying this expansion, the establishment of universities in small cities had both intended and unintended consequences. These institutions became place-making anchors in otherwise economically and demographically stagnant regions, fostering a new social life centered around the youth.

Unbound hukou and rebound innovation in urban China

The Chinese authorities issued the “Guiding Opinions on Further Deepening the Reform of the Household Registration System” in 2014. This policy maintained strict controls on urban hukou in megacities, while slightly less stringent controls were applied in large cities. However, the restrictions on obtaining urban hukou were significantly relaxed in medium-sized cities and completely lifted in small cities. This study examines the causal effects and underlying mechanisms of hukou reform on urban innovation in cities of different sizes, using DID method based on a quasi-natural experiment by the 2014 hukou reform in China. The findings suggest that the hukou reform can significantly promote urban innovation, with particularly strong positive effects observed in large cities in the eastern region, small- and medium-sized cities in the central and western regions, as well as cities with favourable conditions for innovation. The primary mechanisms in which hukou reform influences urban innovation involve enhancing both the quantity and quality of urban labor force, as well as creating a better environment for innovation in cities.

How does the National Key Ecological Function Area policy affect the upgrading of the industrial structure?—based on the examination of the Yellow River Basin in China

The transformation and upgrading of the industrial structure constitute a pivotal task for sustainable economic development, and the factors influencing this process are also of concern to developing countries around the world. Unfortunately, there is still relatively little systematic discussion on the impact of environmental policy on the industrial structure. Against this backdrop, we have employed the multi-period differences-in-differences (DID) model to assess the impact of the implementation of the National Key Ecological Function Area (NKEFA) policy on the industrial structure in the Yellow River Basin. Our findings reveal that this environmental policy fosters the advancement of industrial structure but does not influence its rationalisation. Regarding mediating effects, we confirm the positive impacts of population density and the investment in education. Furthermore, the policy effects are more pronounced in non-ethnic provinces with better basic conditions, whereas ethnic provinces exhibit almost no effect. The policy effects are more significant in large cities than in small and medium-sized cities. These findings enrich the existing exploration of the impact of environmental policy on industrial structure and provide a strong reference for policy practice in developing countries.

Investigating the housing and transportation burden in a Ghanaian city

ABSTRACT Although there is a strong relationship between housing and transportation (H+T) spending, traditional housing affordability estimates from sub-Saharan Africa exclude transportation costs. Also, the H+T literature has few case studies from small cities and developing countries. This dearth of research makes it difficult to understand the housing burden and provide workable solutions. This paper measures H+T affordability in Koforidua, Ghana, based on rental and transportation costs. A household survey comprising 600 renting households was conducted and analyzed using group comparisons and Ordinary Least Square regressions. The results showed that H+T consumes approximately 56% of household income. This is a huge household burden considering the high unemployment rates in developing countries. Household income and size are significantly associated with H+T spending. Interestingly, smaller households have a marginal propensity to spend on H+T than larger households due to dependency ratio and housing choices. We recommend transport and housing subsidies, and affordable housing to ameliorate the H+T burden. Other policy recommendations and actions have been discussed to guide policymakers.

More extremely hot days, more heat exposure and fewer cooling options for people of color in Connecticut, U.S.

It is well-documented that people of color in the U.S. are disproportionately exposed to extreme urban heat. However, most studies have focused on large cities for one point in time, and less is known about how heat exposure changes over time in smaller cities. Here, we present a study of the changing nature of urban heat exposure and cooling strategies for ten cities in Connecticut in the U.S. Our results show that people of color experience more heat exposure and fewer adaptation strategies. They experienced higher overall temperatures, more extremely hot days, and larger increases in heat exposure. Also, they have lower air conditioning ownership rates and lower tree cover. Taken together, the results indicate that people of color are not only exposed to higher temperatures but also disproportionately exposed to increasing temperatures over time. With lower heat adaptation capacity, people of color are more vulnerable to increasing urban heat.

Correlation between fall experience and life functions among community-dwelling older adults in Japan

PurposeThis study investigated the correlation between the risk of falls and life functions, including motor function, cognitive function, and urinary disorders, among older adults residing in small cities in the metropolitan areas of Japan and evaluated the contents of fall prevention instructions. MethodsSixty-nine older adults residing at home participated in this case-control study conducted between September and October 2019. The survey items included questions pertaining to the history of falls; grip strength; the 30-s Chair Stand Test (CS-30), Functional Reach Test (FRT), and Timed Up and Go Test (TUG) scores; mental and cognitive functions [Test Your Memory-Japanese version test (TYM-J)]; living conditions; and urination status [Core Lower Urinary Tract Symptom Score (CLSS)]. ResultsParticipants with a history of falls had significantly lower CS-30 and FRT scores, and significantly higher TUG scores and CLSS than those with no history of falls. Grip strength bore significant correlations with the CS-30 and TUG scores. The CS-30 scores were correlated with the FRT and TUG scores. The FRT scores were correlated with the TUG and French State Activity Index (FAI) scores. The TUG scores were correlated with the TYM-J and FAI scores. The CLSS showed no significant correlations with the remaining items. The FRT scores and CLSS exerted a significant effect on the risk of experiencing falls. ConclusionBoth balancing ability and micturition status affect fall risk and should be considered in treatment strategies for urinary disorders in fall prevention programs for older adults.

Outdoor Thermal Comfort and Sustainability of Urban Village Life in The Small Ancient City at Tropic Area Yogyakarta, Indonesia: Approach with ENVI-Met

Several studies examining urban villages, sustainability, and their relation to thermal comfort in Indonesia have stated uncomfortable perceptually. Through this research which was conducted in an urban village in Yogyakarta by using the thermal measurement method, shows that average temperature reaches 30.14℃, humidity 72.90%, wind speed 0.93 m/s, MRT 44.70℃, PMV 0.79 or warm sensation. It shows that thermal comfort in urban villages is still in normal condition. However, several intervention variables which are used in the simulation using ENVI-met to get the better thermal condition do not significantly change the thermal parameters, but only slightly. The sensation remains warm, at certain times it is hot or very hot, the highest PPD level achieved is 59%. Even though the results are less than expected, based on the range of thermal comfort standard the current thermal comfort still supports sustainable urban living.

PERSPECTIVA TEÓRICO-METODOLÓGICA E PROPOSTA DE ANÁLISE SOBRE PEQUENAS CIDADES, CIDADES LOCAIS, PEQUENAS LOCALIDADES, ESPAÇO MIKRIPOLITANO

This study aims to analyze and define the appropriate terminology for "small cities," "local cities," "small localities," or "mikripolitan space". To achieve this, one of the methodological procedures was a comprehensive literature review regarding the subject, highlighting key authors of Brazilian geography, such as Pierre Monbeig, Milton Santos, Roberto Lobato Corrêa, Tania Maria Fresca, and Ângela Maria Endlich. The study underscores the lack of available research on these geographical spaces. Monbeig (1957) argued that small cities warrant investigation due to their unique complexity. Santos (2008) also acknowledged the paucity of studies on these cities, accentuating their significance as entities comparable to large cities in developing countries. In Espaço e Método [Space and Method], Santos (2008b [1985]) expounded on how complexity increases as the scale of study diminishes. While Endlich (2017) reported an increase in academic production on small localities, she nonetheless observed that it remains insufficient. Data from the 2022 Demographic Census demonstrated that in 88.01% of Brazilian municipalities the population is less than 50,000, thus reflecting the importance of this topic. In order to exemplify, the study also proposes to analyze the network and the intermediate geographic region of Cascavel in the state of Paraná. Keywords: Small Cities; Local Cities; Small Localities; Mikripolitan Space; Geographic Region.

Attitude of Romanian students and their families concerning waste management

Abstract Waste recovery, recycling included, is an important step in waste management, preceding final disposal. In 2018, according to Eurostat, the recycling rate of municipal waste was 47% in the European Union and only 11.1% in Romania. Thus governmental institutions have implemented new measures in order to reduce environmental pollution by ineffective waste management. In 2022, 535 students aged 22-24.5 years, males and females, studying in Craiova (one of the six largest academic cities of Romania), were asked to answer an 18-item questionnaire regarding their and their families’ attitude towards waste recycling. Most of the students (60.7%) were residents in the university city, while the others - in smaller cities or in villages of the region. Only 38.3% of the subjects (N = 205) declare their families recycle waste; the most common excuse for no-recycling (37.8%) is the lack of recycle bins in the house proximity. Only 20 families (3.7%), all of them living in Craiova, take the fried oil to collecting points in supermarkets; most of the others eliminate it in the sewerage system, especially those from outside the city (p < 0.01). Seventy-five students (14%) are not able to mention any recent measure taken by the government in order to reduce plastics environmental pollution; the others discuss about the increased number of recycle bins around the city (53.2%), recycling of single-use plastics (34.5%) or use of biodegradable bags (25.2%). No-recycling (42%), using daily his/her own car (18.7%, p < 0.01 males vs. females), using too much plastics (11.2%) are the most frequent self-reported students’ disregards for the environment. Most of the subjects consider environmental health of essential importance (88.7%) and would like to participate in environment protection actions (92.5%). Romanian students seem to have a positive attitude and like to be involved in the environment protection, without a significant influence regarding the gender and the residence place. Key messages • Education and information are essential tools to make people ecologically aware. • Recycling is one of the best ways to have a positive impact on both natural and community environment.

Vaccine conspiracy beliefs are the main determinant of adult vaccine hesitancy

Abstract Background Many factors influence the level of vaccine hesitancy. The COVID-19 pandemic demonstrated that conspiracy beliefs are an important element of overwhelming misinformation. The main aim of the study was to assess the relationship between vaccine hesitancy (VH) and vaccine conspiracy beliefs (VCB) in Polish society. Methods The analysis was conducted using data from an online survey of 2189 Internet users conducted in November 2021. Uni- (ULRM) and multivariable linear regression (MLRM) models were developed for vaccine hesitancy as a dependent variable. The independent variables included VCB score (VCBS), health (HL) and e-health literacy (eHL), Internet (IU) and social media use (SMU), political views (PV), and sociodemographic variables. Results The VCBS, eHL, HL, age, income, vocational and marital status, place of residence, PV, IU, and SMU were significant predictors of VH in ULRMs. A significant relationship with VH was maintained in MLRM for all independent variables enlisted earlier, apart from age, income, and vocational status. Respondents with higher VCBS were more likely to have higher VH (B, 95%CI: 0.38, 0.37-0.40). Those with undetermined HL had higher VH than persons with sufficient HL (B, 95%CI: 0.13, 0.06-0.20). A higher level of eHL predicted a lower level of VH (B, 95%CI: -0.01, -0.012 - -0.03). Lower IU and higher SMU were associated with higher VH (B, 95%CI: 0.16, 0.02-0.30, and 0.10, 0.03-0.17, respectively). Supporters of far right-wing party showed higher HV than supporters of the governmental party (B, 95%CI: 0.16, 0.07-0.27). Finally, singles showed higher HV than married (B, 95%CI: 0.07, 0.01-0.13), and residents of small cities had higher HV than residents of rural areas (B, 95%CI: 0.08, 0.004-0.15). Conclusions The vaccine conspiracy beliefs play a major role in the development of VH. The interventions aimed at the change of antivaccination attitudes should address the problem of widespread conspiracy beliefs. Key messages • Conspiracy beliefs are an important determinant of attitudes toward vaccination. • The development of adequate digital health literacy may be a protective factor against vaccine hesitancy.

Epidemiological model can forecast COVID-19 outbreaks from wastewater-based surveillance in rural communities

Wastewater has emerged as a crucial tool for infectious disease surveillance, offering a valuable means to bridge the equity gap between underserved communities and larger urban municipalities. However, using wastewater surveillance in a predictive manner remains a challenge. In this study, we tested if detecting SARS-CoV-2 in wastewater can forecast outbreaks in rural communities.Under the CDC National Wastewater Surveillance program, we monitored the SARS-CoV-2 in the wastewater of five rural communities and a small city in Idaho (USA). We then used a particle filter method coupled with a stochastic susceptible-exposed-infectious-recovered (SEIR) model to infer active case numbers using quantities of SARS-CoV-2 in wastewater.Our findings revealed that while high daily variations in wastewater viral load made real-time interpretation difficult, the SEIR model successfully factored out this noise, enabling accurate forecasts of the Omicron outbreak in five of the six towns shortly after initial increases in SARS-CoV-2 concentrations were detected in wastewater. The model predicted outbreaks with a lead time of 0 to 11 days (average of 6 days +/- 4) before the surge in reported clinical cases.This study not only underscores the viability of wastewater-based epidemiology (WBE) in rural communities—a demographic often overlooked in WBE research—but also demonstrates the potential of advanced epidemiological modeling to enhance the predictive power of wastewater data. Our work paves the way for more reliable and timely public health guidance, addressing a critical gap in the surveillance of infectious diseases in rural populations.

Micro and Small Business Growth Drivers in Nigeria: Evidence from Small Cities Small Federating State

This study involves a comprehensive survey of about 1500 micro and small businesses across three major cities in one of the smallest states in Nigeria (Ebonyi State). Based on the cross-sectional data generated, a linearized Tobit regression and a robust T-Test statistical technique are applied to comparatively examine how internal firm attributes, market attributes, and socioeconomic and macroeconomic conditions affect the growth of micro and small businesses in a typical small state and small cities. The results reveal a key challenge to be the dominance of the business space in small cities by micro and largely informal enterprises.

The power of speed: High-speed railways and scientific research competitiveness in China

This paper investigates the impact opening of high-speed railways (HSR) on scientific research competitiveness using data from the National Natural Science Foundation of China (NSFC) research grants. We employ a difference-in-differences framework to estimate the causal effects of the treatment universities located in cities connected by HSR. Our results indicate that the treatment universities experience significant improvements in their scientific research competitiveness. To understand the underlying mechanisms, we reveal the extensive positive effects of HSR on human capital accumulation, government funding, and information resources. These findings shed light on the microscopic mechanisms that facilitate positive spillover of knowledge creation and innovation resources from large cities to small cities through transportation infrastructure.

Ecological and allergenic significance of atmospheric pollen spectra from a Grassland-Savanna ecotone in North West province, South Africa

Southern Africa’s floral, topographic and climatic diversity manifests in distinctive bioregions where aerobiology studies are needed to manage allergenic health problems, especially in urban areas. Previous studies underline different seasonal pollen fluctuations for the biomes, encouraging regional studies. These studies have been previously restricted to large cities such as Cape Town, Johannesburg and Pretoria whereas small cities such as Potchefstroom in the North-West province are understudied. The South African Pollen Monitoring Network (SAPNET) seeks to fill this lacuna, enhancing ecological and health-related knowledge, with regard to the allergenicity of the recorded pollen. Here, we investigate plant phenology and resulting pollen production within the Grassland and Savanna biomes around Potchefstroom, a fast-growing city in the North West province, comparing it with other SAPNET sites. As a SAPNET initiative, pollen monitoring in Potchefstroom involved monthly collections using a Lanzoni 7-day spore trap over 13 months from December 2022 to 2023. This facilitated the development of a preliminary pollen calendar and a pollen atlas, detailing pollen types’ morphology, ecology, pollination modes, and allergenicity. Initial findings revealed Potchefstroom’s pollen calendar, with tree pollen (60% of the Annual Pollen Index (API)) mainly from northern hemisphere species such as Cupressus (c. 11% of API) and Platanus (c. 18%), which released pollen in spring. Grass pollen was predominant from November to April (c. 18% of API). Potchefstroom recorded South Africa’s highest levels of Ambrosia pollen (c. 7% of API), a major allergen, in March and April. Noteworthy is the unusual abundance of pollen of the neophyte Ulmus (c. 14%) in December. This study highlights the pollen patterns of the Grassland and Savanna biomes around Potchefstroom. The region, with its mosaic of urban spaces, natural grass-/woodland, and agricultural land, exhibits distinct characteristics when contrasted with major, more densely populated cities such as Bloemfontein, Pretoria, and Johannesburg.

Impact of vegetation coverage and configuration on urban temperatures: a comparative study of 31 provincial capital cities in China

Urban vegetation plays a crucial role in regulating temperatures and heat waves in urban areas. However, the influence of vegetation coverage and its configuration on surface temperatures in different climate zones at a national scale is unclear. To address this, we utilized high-resolution data to detect spatial patterns for 31 provincial capital cities in China. We integrated day and night surface temperatures to determine the influence of vegetative coverage and configuration on urban temperatures across different climate zones and city sizes. Our study revealed that a subtropical monsoon climate and medium-sized cities had the highest vegetative coverage and shape complexity. The best connectivity and agglomeration of vegetation were found in a temperate monsoon climate and large cities. In contrast, small cities, especially those under a temperate continental climate, had low vegetation coverage, high fragmentation, and weak agglomeration and connectivity. In addition, vegetative coverage had a negative impact on daytime surface temperatures, especially in large cities in a subtropical monsoon climate. However, an increase in vegetation coverage could result in warming at night in small cities in temperate continental climates. Although urban vegetation configuration also contributed to moderating surface temperatures, especially at night, they did not surpass the influence of vegetation coverage. The effect on nighttime temperatures of the configuration of vegetation increased by 3–6% relative to that of daytime temperatures, especially in large cities in a temperate monsoon climate. The contribution vegetation coverage and configuration interaction to cooling efficiency decreased at night, especially in medium-sized cities in a temperate continental climate by 3–5%. In addition, this study identified several moderating effects of natural and social factors on the relationship between urban vegetation coverage and surface temperatures. High duration of sunshine, low humidity and high wind speed significantly enhanced the negative impact of vegetation coverage on surface temperatures. In addition, the moderating effect of vegetation coverage was more pronounced in low population density cities and high gross domestic product. This study enhances understanding of the ecological functions of urban vegetation and provides a valuable scientific basis and strategic recommendations for optimizing urban vegetation and improving urban environmental quality.

Causes of the unremitting high ambient levels of PM10 in a suburban background site in NE Spain

Atmospheric PM10 and benzo(a)pyrene (BaP) concentrations in Manlleu (NE Spain) have remained high from 2008 to 2023, frequently exceeding EU limit/target values, and reaching BaP levels up to six times higher than urban averages in Spain. Furthermore, PM speciation campaigns were carried out in 2013, 2014–2015, 2016–2017 and 2021–2022. Chemical mass closure for autumn-winter showed a consistent PM10 composition for the different PM speciation campaigns, comprising 46–53% organic matter (OM), 18–26% secondary inorganic aerosol (SIA), 13–23% mineral matter (MM), and 5–9% elemental carbon (EC). Trend analysis revealed very light decrease and constant concentrations for PM10 and BaP, respectively over the study period, emphasizing the need for compliance with current and forthcoming EU air quality directives, the last aiming to halve PM10 limit values. Source apportionment of samples of the sporadic campaigns identified biomass burning (BB, 17.5 μg m−3, 48%) and MM and industry (16.3 μg m−3, 44%) as the main autumn-winter PM10 contributors, with high SIA concentrations attributed to several factors, including high ammonia (NH3) emissions. Local topography and meteorological conditions contribute to aggravate PM10 pollution. While metal concentrations have decreased since 2013, suggesting reduced industrial emissions, persistently high OM and EC concentrations indicate ongoing issues with BB emissions from domestic, commercial, and agricultural sources. Online analysis of black carbon (BC) and non-refractory PM1 components during winter 2016–2017 confirmed domestic and commercial BB as the primary sources of the BB contributions. These findings highlight the need of the implementation of more effective measures in reducing BB and agricultural/farming NH3 emissions. This study highlights the relevance of these issues for similar towns, the probable unremitting problem over the last decade, and the necessity of enhanced monitoring in small cities and policy actions to meet air quality standards under the new EU directive.

Will Higher Education Development Influence the Escape from the Middle-income Trap? Insights from Northeast China

This article constructs an index model of higher education development from the 2020 data of 34 prefecture-level cities in Northeast China. GeoDetector was used to find the explanatory power of higher education for economic growth. The stronger the explanatory power, the greater its effect on enabling a city to move beyond the middle-income stage. The results indicated that economically developed cities had advanced levels of higher education development. The development level of higher education in provincial capitals and sub-provincial cities is among the highest in Northeast China. Furthermore, higher education significantly explains economic growth, with the scale of education having a stronger explanatory power than the quality of education. In addition, regional heterogeneity exists in the explanatory power of the scale and quality of education on economic growth. Specifically, the effect of the scale of higher education on economic growth is significantly greater than the quality of higher education in large cities. In contrast, the opposite is true in medium-sized cities. For small cities, the effect of higher education on economic growth is minimal. JEL Classification O11
