title: Wage rigidity and unemployment: a comment on Kohn

description: ABSTRACT This paper examines loanable fund models with a stabilized interest rate, in which the banking system bridges the gap between the flow of demand and the provision of funds. A typical Mickselian model is developed to emphasize the importance of credit and inflation (deflation) in closing the gap between savings and investment. Substituting the nominal interest rate for the real - an appropriate modification in a model whose inflation is relevant - and using the Robertsonian definition of income, we realize that, depending on the reaction of ‘lacking’ and investment to inflation, there is the possibility of the system become unstable. By introducing unemployment into the system, we realize that investment is more sensitive than the lack of inflation, the greater the degree of wage flexibility, the greater the level of unemployment balance, in the face of the demand shock, and the greater the chances of macroeconomic instability. Finally, we demonstrate that if we replace the Robertsonian definition of income with Keynesian, investment becomes more sensitive to inflation, making wage rigidity necessarily a good deal.

title: Brazilian external debt in francs, 1888-1956

description: ABSTRACT Although the share of the debt in French francs in total Brazilian debt was of only 6% in 1930, the analysis is of interest due to the marked concentration of inflows just before World War I, to the concentration of indebtedness in high risk loans to states and municipalities and to the fact that France was the only creditor country to return to gold with a broken parity. The process of Brazilian progressive indebtedness in francs is described and the performance of loans in different currencies is evaluated in relation to alternatives such as the purchase of government bonds.

title: Genetic diversity of Rhododendron henanense subsp. lingbaoense revealed by whole-genome resequencing

description: Abstract Rhododendron henanense subsp. lingbaoense Fang (Rhl) is a subspecies endemic to China with important ornamental value. Recently, the Rhl population has been shrinking as a result of its limited distribution range, poor natural regeneration, and rising human exploitation. In this study, high-quality single nucleotide polymorphisms (SNPs) identified through whole-genome resequencing were examined in 50 individuals from four populations of Rhl with a depth of ~34× to evaluate genome-level diversity and population structure. Population structure profiling, principal component analysis, and phylogenetic analysis clustered the Rhl samples into two groups corresponding to their geographical distributions. Analysis of SNPs indicated that Rhl populations have high genetic diversity and little genetic differentiation. Additionally, demographic history indicated that all four populations of Rhl have experienced long-term population decline. The above findings showed that we should take action to protect this rare species.

title: SYNTHESIS, CHARACTERIZATION OF A CHITOSAN SCHIFF BASE AND COPPER COMPLEXES USED AS A MODIFIED ELECTRODE

description: A new material formed by Shiff base (chitosan and ortho-vanillin) and copper were synthesized and characterized by UV-visible, infrared spectroscopies, thermal analysis, elemental analysis, electron microscopy, 1H NMR spectra and electrochemical techniques. In this study, it was possible to identify the formation of Schiff’s base (BS), with a degree of substitution of 42.5% by NMR. The electron microscopy study indicates an amorphous character for BS. The material was used to build an electrode, which proved to be sensitive to the addition of nitrite, making it possible to quantify it. The values obtained for detection limit and limit of quantification of the electrode formed BS-Cu were 0.062 µmol L-1 and 0.21 µmol L-1, respectively.

title: Keynes’s monetary theory: a partial survey

description: ABSTRACT The title of the paper alerts the reader to the fact that while the role of money in Keynes’s earlier work is alluded to, it is mostly the monetary contribution of the General Theory (to which the author is particularly partial) which is surveyed here. The General Theory represents a breakthrough in monetary theory both broadly and narrowly defined. Money in the General Theory is all-pervasive. It is essential in the sense of Radner and Hahn. Money is also essential in allowing Keynes to break away, more profoundly than before, from equilibrium economics. Monetary theory narrowly defined also represents a breakthrough: speculative demand is a revolutionary concept, driving a wedge between the rate of interest and the rate of profit. The concept is elaborated and compared with Hicks’s treatment. The article ends with a brief section on the finance motive and endogenous money.

title: Regional exports and imbalances: a portfolio analysis

description: ABSTRACT This paper estimates the impact of regional export structures on the risk and return of regional export portfolios. The Markowitz model is used to assess the risk and return of export products structures of three Brazilian economic regions. More specifically, the paper tests the hypothesis that economic regions with highly diversified export structure will observe more efficient export portfolios than those with only moderate or no portfolio diversification. In order to test this hypothesis, we used the export structures of three Brazilian economic regions: the South, the Southeast and the Northeast. The results show that portfolio theory can provide policymakers with an alternative way of assessing export earnings instability and export promotion strategies.

title: Sources of root-knot nematode (Meloidogyne enterolobii) resistance in sweetpotato genotypes

description: ABSTRACT The root-knot nematode (RKN) Meloidogyne enterolobii is gaining importance all around the world, including Brazil, damaging sweetpotato genotypes with known resistance to other RKN species, making it challenging to generate new resistant genes. This study aimed to assess the levels of resistance of 10 advanced sweetpotato cultivars to this nematode species. Two experiments were carried out in 2018/2019 and 2021/2022 seasons, under greenhouse conditions in Brasília-DF, Brazil. A completely randomized block design with six replicates of one plant/plot/treatment was used. The gall index (GI) and egg mass index (EMI) in the root system of each plant, the number of eggs and juveniles per gram of root with galls (NERG), and the nematode reproduction factor (RF) were determined. M. enterolobii resistance is present within three of the evaluated clones: BGBD 1399, MD 1609024, and MD 1610036, therefore demonstrating their potential as sources of resistance genes to assist breeding efforts to release cultivars, and help to reduce the impact and spread of this RKN.

title: Estimates of disease burden attributed to particulate matter in northern part of Thailand

description: During the dry season, the most severe haze problems happen in northern Thailand, and atmospheric PM10 and PM2.5 concentrations during this period exceeded national ambient air quality standards. A potential health risk to the local population was also exacerbated by elevated PM10 and PM2.5 concentrations. Throughout the study years of 2012 to 2016, the total quantity of PM10 emissions from all biomass types, including forests, savannas and grasslands, and agriculture, were 298,002, 279,476, 333,167, 308,540, and 415,173 tons, respectively and that from PM2.5 were 218,283, 204,018, 242,502, 224,720, and 301,494 tons, respectively. Forests generated the majority of PM10 emissions (88.1–91.8%), followed by savannas and grasslands (7.5–11.2%) and agricultural (0.7–1.0%). In consideration with others arthrosporic emissions, biomass burning contributed to around 88% of total emissions in the nine provinces of upper northern Thailand. In accordance with the correlation between measured PM10, PM2.5 and MAIAC-AOD, a linear regression model was developed to predict the PM10, PM2.5 concentration in the area without monitoring station. However, because PM2.5 monitoring was not available in any other studied province during the study period, the prediction of PM2.5 concentration was only made for Chiang Mai. The most MAIAC-AOD was retrieved during the summer, between February and May, at a ratio of 62.5%, followed by the winter (34.8%) and the rainy season (2.7%). The province with higher predicted PM10 concentration showed higher DALYs. Chiang Mai had the greatest DALYs of COPD in 2014, with 4,359 years per 100,000 population, under the highest predicted PM10 concentration of 66 µg/m3. Whereas Lamphun had the greatest DALYs for acute bronchitis, at 4,782 years per 100,000 population, which was associated with the highest PM10 concentration of 65 µg/m3 during in 2015. During 2014-2016, the DALYs of COPD attributed to PM2.5 were 2,589, 2922, and 3,567, respectively, and the DALYs of lung cancer attributed to PM2.5 were 576, 809, and 843, respectively. In conclusion, the ability of MAIAC-AOD to predict the PM10 and PM2.5 concentration at a 1-km resolution could be helpful in managing air pollution control, monitoring, and assessment of the health risks attributed to particulate matter.

title: Post-COVID-19 Cardiopulmonary Symptoms: Predictors and Imaging Features in Patients after Hospital Discharge

description: Abstract Background Most of the evidence about the impact of the post-acute COVID-19 Syndrome (PACS) reports individual symptoms without correlations with related imaging. Objectives To evaluate cardiopulmonary symptoms, their predictors and related images in COVID-19 patients discharged from hospital. Methods Consecutive patients who survived COVID-19 were contacted 90 days after discharge. The Clinic Outcome Team structured a questionnaire evaluating symptoms and clinical status (blinded for hospitalization data). A multivariate analysis was performed to address the course of COVID-19, comorbidities, anxiety, depression, and post-traumatic stress during hospitalization, and cardiac rehabilitation after discharge. The significance level was set at 5%. Results A total of 480 discharged patients with COVID-19 (age: 59±14 years, 67.5% males) were included; 22.3% required mechanical ventilation. The prevalence of patients with PACS-related cardiopulmonary symptoms (dyspnea, tiredness/fatigue, cough, and chest discomfort) was 16.3%. Several parameters of chest computed tomography and echocardiogram were similar in patients with and without cardiopulmonary symptoms. The multivariate analysis showed that PACS-related cardiopulmonary-symptoms were independently related to female sex (OR 3.023; 95% CI 1.319-6.929), in-hospital deep venous thrombosis (OR 13.689; 95% CI 1.069-175.304), elevated troponin I (OR 1.355; 95% CI 1.048-1.751) and C-reactive protein during hospitalization (OR 1.060; 95% CI 1.023-1.097) and depression (OR 6.110; 95% CI 2.254-16.558). Conclusion PACS-related cardiopulmonary symptoms 90 days post-discharge are common and multifactorial. Beyond thrombotic and markers of inflammation/myocardial injury during hospitalization, female sex and depression were independently associated with cardiopulmonary-related PACS. These results highlighted the need for a multifaceted approach targeting susceptible patients.
