This research aims to analyze the relationship between economic, social and digital performance in cities of different sizes in Brazil. Data provided by the following official agencies: National Treasury Secretariat, National Mayors' Front and Risk Classification Agency were used. Pearson's correlation was used to identify the influence of digital, social, and economic performance variables in cities divided into groups based on the number of inhabitants. There was a strong correlation between Communication and Information Technologies and social and economic aspects. The greater the needs of cities, the more intense is the use of Communication and Information Technologies, reinforcing the establishment of the perspective of smart cities.

This study examines the effect of incorporating taxation into the incumbency voting model using aggregate economic data for Canadian federal elections from 1953 to 1988. Although Canadian election campaigns tend to be dominated by economic performance issues, taxation, as measured by open-ended questions in the national election studies, has not been a salient campaign issue among voters. None the less, voters as consumers in the market economy have an interest in government policies that affect after-tax income. Furthermore, as economic citizens, voters have an interest in taxation as a measure of government efficiency – the costs of providing public services – independent of benefits generated by government. Paralleling American and British results, the economic and fiscal performance variables behave as expected in the incumbency model. Income change has a positive effect, and the rate of inflation and unemployment a negative effect, on incumbency voting. The relationship between taxation and incumbency voting is negative, both through its effect on after-tax income and also directly, independent of income. The results are consistent with an interpretation which suggests that voters, responding to the public agenda for economic performance and to a private agenda for taxation, behave both as politic consumers and as economic citizens.

Financial crises have had a decisive influence on banking regulations in Spain. During the mid-19th century the publication of the financial statements of banks was considered key to the stability of the financial system. All new joint stock banking companies were to publish their statements in the Madrid Gazette in return for the privilege of limited liability. Similar obligations were placed on issuing banks. The copious publication of financial statements coincided with a period of financial prosperity. However, the crises that followed from 1864 to 1868 led to a reduction in the official publication of statements. This paper is concerned with an early response to crises in financial reporting. The study focuses on the relationship between the publication of accounting statements by banks and the GDP in Spain during the mid-19th century. The results suggest that the frequency of publication of financial statements may be an indicator of economic performance.

AbstractObjectivesThe results of existing studies on bisphenol A (BPA) and puberty timing did not reach a consensus. Thereby we performed this meta-analytic study to explore the association between BPA exposure in urine and puberty timing.MethodsMeta-analysis of the pooled odds ratios (OR), prevalence ratios (PR) or hazards ratios (HR) with 95% confidence intervals (CI) were calculated and estimated using fixed-effects or random-effects models based on between-study heterogeneity.ResultsA total of 10 studies involving 5621 subjects were finally included. The meta-analysis showed that BPA exposure was weakly associated with thelarche (PR: 0.96, 95% CI: 0.93–0.99), while no association was found between BPA exposure and menarche (HR: 0.99, 95% CI: 0.89–1.12; OR: 1.02, 95% CI: 0.73–1.43), and pubarche (OR: 1.00, 95% CI: 0.79–1.26; PR: 1.00, 95% CI: 0.95–1.05).ConclusionsThere was no strong correlation between BPA exposure and puberty timing. Further studies with large sample sizes are needed to verify the relationship between BPA and puberty timing.

Takis Zenetos was enthusiastic about the idea of working from home, and believed that both architecture and urban planning should be reshaped in order to respond to this. He supported the design of special public spaces in residential units, aiming to accommodate the inhabitants during working hours. This article argues that Zenetos’s design for “Electronic Urbanism” was more prophetic, and more pragmatic, than his peers such as Archigram and Constant Nieuwenhuys. Despite the fact that they shared an optimism towards technological developments and megastructure, a main difference between Zenetos’s view and the perspectives of his peers is his rejection of a generalised enthusiasm concerning increasing mobility of people. In opposition with Archigram, Zenetos insisted in minimizing citizens’ mobility and supported the replacement of daily transport with the use advanced information technologies, using terms such as “tele-activity”. Zenetos was convinced that “Electronic Urbanism” would help citizens save the time that they normally used to commute to work, and would allow them to spend this time on more creative activities, at or near their homes. The main interest of “Electronic Urbanism” lies in the fact that it not only constitutes an artistic contribution to experimental architecture, but is also characterized by a new social vision, promising to resynchronize practices of daily life. An aspect that is also examined is the relationship of Zenetos’s ideas and those of the so-called Metabolists in the 1960s in Japan, including Kenzo Tange’s conception of megastructures. Zenetos’s thought is very topical considering the ongoing debates about the advanced information society, especially regarding the social concerns of surveillance, governance, and sovereignty within the context of Big Data. His conception of “tele-activities” provides a fertile terrain for reflecting on potential implications and insights concerning home-office conditions not only within the context of the current pandemic situation but beyond it as well.

Abstract Introduction The sodium voltage-gated channel alpha subunit 7 (SCN7A) has been associated to renal Na regulation and hypertension. This study explores the relationship between blood pressure (BP) and urinary overnight Na/K ratio (UONaK) in hypertensives (HT) and normotensive (NT) subjects from from National Heart, Lung and Blood Institute funded, Family Blood Pressure Program (FBPP) that were genotyped for 3 SNPs for SCN7A: CV2161217, CV 356958 and CV433036. Hypothesis Genetic variations in the SCNA7 are differently associated to BP and UONaK in HT and NT. Methods 1,749 subjects genotyped for SCN7A SNPs CV2161217, CV 356958 and CV433036 were analyzed from FBPP. Subjects with diastolic BP (DBP) ≥80 or systolic BP (SBP) ≥130 mmHg were classified HTN; subjects with SBP <130 and DBP <80 mmHg were classified as NT. UONAK was calculated by dividing overnight Na by K concentration. Correlation analysis done with partial variables (use of antihypertensive drug, use of diuretics, overnight urine creatinine). Results For the CV2161217, HTN group (n=1,030), 52% had C/C, 39% C/T and 9% T/T. In NT group (n=719), 52% had C/C, 38% C/T and 10% T/T. In the HT group, subjects with CC genotype showed strong correlation between DBP and UONaK (Fig 1a) while no significant correlation with SBP. Those with CT genotype maintained the correlation between SBP and UONaK (r=0.10, p=0.03) with no correlation with SBP. The TT showed no correlation between UONaK and SBP or DBP. In the NT, subjects with TT genotype showed strong correlation between DBP and UONaK (Fig 1b) and with SB (r=0.256, p=0.03). Those with CT or TT genotypes showed no correlation between UONaK and SBP or DBP. Similar finding were obtained for CV356958 SNP; no similar association was observed in the CV433036 SNP. Conclusions Subjects with the genetic variations in the SCNA7, such as CV2161217 and CV 356958 SNPs, showed significant correlation between blood pressure and overnight urinary sodium potassium. This finding could have important implications in non dipping status observed in some hypertensive patients. Funding Acknowledgement Type of funding source: None

Purpose – The purpose of this paper is twofold. First, the study aims to investigate the relationship between the altmetric indicators from ResearchGate (RG) and the bibliometric indicators from the Scopus database. Second, the study seeks to examine the relationship amongst the RG altmetric indicators themselves. RG is a rich source of altmetric indicators such as Citations, RGScore, Impact Points, Profile Views, Publication Views, etc. Design/methodology/approach – For establishing whether RG metrics showed the same results as the established sources of metrics, Pearson’s correlation coefficients were calculated between the metrics provided by RG and the metrics obtained from Scopus. Pearson’s correlation coefficients were also calculated for the metrics provided by RG. The data were collected by visiting the profile pages of all the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India). Findings – The study showed that most of the RG metrics showed strong positive correlation with the Scopus metrics, except for RGScore (RG) and Citations (Scopus), which showed moderate positive correlation. It was also found that the RG metrics showed moderate to strong positive correlation amongst each other. Research limitations/implications – The limitation of this study is that more and more scientists and researchers may join RG in the future, therefore the data may change. The study focuses on the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India). Perhaps further studies can be conducted by increasing the sample size and by taking a different sample size having different characteristics. Originality/value – Being an emerging field, not much has been conducted in the area of altmetrics. Very few studies have been conducted on the reach of academic social networks like RG and their validity as sources of altmetric indicators like RGScore, Impact Points, etc. The findings offer insights to the question whether RG can be used as an alternative to traditional sources of bibliometric indicators, especially with reference to a rapidly developing country such as India.

The paper seeks to investigate the environmental, social and economic impacts of the Soil and Water Management Program in Micro-basins in Paraná for farm producers participating in the program in the town of Irati/PR and region. The agency affirms that the initiative aims to generate a better quality of life for the residents near the micro-basins, as well as to help in the agricultural productive capacity of the region. The paper’s results showed that 85% of the producers believe that the program not only fulfilled what it proposed but also entailed several positive points and significant changes in the relationship between rural producers and the work in the field. Thus, the program assumes an essential role in its condition of public policy, generating income, social welfare, and environmental protection in the Irati/PR region.

The study poses to investigate the relationship between the level of environmental disclosure and economic performance of open capital companies as classified by the Você S/A – As Melhores Empresas para Você Trabalhar (The Best Companies to Work) guide. A descriptive study, employing a quantitative approach, was conducted via documental analysis of financial statements of the therein featured, 21 open capital companies. Survey results evidence that: a) in the environmental disclosure categorization, 680 data entries were found, ranging from 99 deemed complete information, 126 as incomplete and 455 absent; b) in terms of environmental disclosure score levels, 55% of the companies were graded as unsatisfactory, 35% regular and 9% good; and c) the relationship between corporate environmental disclosure levels and economic performance revealed bleak correlation. Thus, once employing the Data Envelopment Analysis (DEA) methodology, the study concludes that not all companies that presented higher environmental information disclosure levels attained efficient economic performance.
