We use the COVID-19 pandemic period in 2020 as an exogenous shock event to assess in how far climate risks measured by carbon exposure have entered and established themselves in the valuation of global stocks. In addition to descriptive analyses, we conduct cross-sectional panel regressions to assess the influence of carbon intensity levels on return and risk characteristics during and after the shock period. Furthermore, a difference-in-differences model setup allows us to infer whether these influences were significantly different when comparing pre-shock, shock, and post-shock periods. We find that carbon intensity affected returns significantly and negatively during a time of high uncertainty. In fact, high-emitting stocks suffered significantly more compared to the pre-crisis period. However, they could make up for their additional losses in the recovery period. In line with their high-risk exposure towards stranded assets and climate policy uncertainty, carbon-intensive stocks face higher risk levels in more stable economic times, thus justifying a carbon premium.

Antecedentes. La complejidad ambiental observada en una localidad ha sido estudiada a través de un modelo isomórfico en el que se anticipa la emergencia de dos identidades: una entrópica y otra neguentrópica. En situaciones de riesgo, escasez e insalubridad, las comunidades se organizan para reducir los efectos de los desastres naturales sobre la salud comunitaria. Objetivo. Especificar un modelo para el estudio del estrés y la resiliencia comunitaria ante los eventos de riesgo ambiental y los desastres naturales. Método. Se llevó a cabo un estudio no experimental, transversal y exploratorio con una selección no probabilística de 600 afectados por las inundaciones de un rio en la zona del centro de México. Resultados. Se encontraron diferencias significativas entre hombres y mujeres con respecto a sus niveles de riesgo, estrés y resiliencia que sirvieron para especificar el modelo de relaciones de dependencia entre las variables que explican la complejidad ambiental isomórfica. Discusión. En relación con otras especificaciones de modelos se recomienda incluir las variables con la finalidad de demostrar las trayectorias lógicas de relaciones de dependencia propuestas.Background. Environmental complexity observed in one locality has been studied through an isomorphic model in which the emergence of two identities are anticipated: an entropic and other neguentropic. At risk, shortages and unsanitary conditions, communities are organized to reduce the effects of natural disasters on community health. Objective. Specify a model for the study of stress and community resilience to environmental risk events and natural disasters. Method. a non-experimental, cross-sectional and exploratory study with a nonrandom selection of 600 affected by the flooding of a river in the downtown area of Mexico was held. Results. significant differences between men and women regarding their risk levels, stress and resilience that served to specify the model of dependency relationships between variables that explain the environmental complexity isomorphic found. Discussion. For other specifications recommended models include variables in order to demonstrate the logical paths proposals dependency relationships.

<abstract> <p>This paper examines the effect of acquirer likelihood on future stock returns. In sharp contrast to prior findings, acquirer likelihood is a strong and negative predictor of cross-sectional future returns after controlling for target likelihood. If takeover exposure represents a risk premium, the effect on stock valuation should only present in either likelihood measure (acquirer or target likelihood). This evidence casts doubt on the rational risk explanation, but is consistent with a relative mispricing story. Investors take positions accordingly to explore profits from takeovers. Profits from trading strategy based on takeover probability are concentrated in stocks with high misvaluation characteristics, including small size, value, high momentum, high investment, and low turnover firms, as well as both high and low issuance (or accrual) firms.</p> </abstract>

Abstract A subset of long-duration spaceflight astronauts have experienced ophthalmic abnormalities, collectively termed spaceflight-associated neuro-ocular syndrome (SANS). Little is understood about the pathophysiology of SANS; however, microgravity-induced alterations in intracranial pressure (ICP) due to headward fluid shifts is the primary hypothesized contributor. In particular, potential changes in optic nerve (ON) tortuosity and ON sheath (ONS) distension may indicate altered cerebrospinal fluid dynamics during weightlessness. The present longitudinal study aims to provide a quantitative analysis of ON and ONS cross-sectional areas, and ON deviation, an indication of tortuosity, before and after spaceflight. Ten astronauts undergoing ~6-month missions on the International Space Station (ISS) underwent high-resolution magnetic resonance imaging (MRI) preflight and at five recovery time points extending to 1 year after return from the ISS. The mean changes in ON deviation, ON cross-sectional area, and ONS cross-sectional area immediately post flight were −0.14 mm (95% CI: −0.36 to 0.08, Bonferroni-adjusted P = 1.00), 0.13 mm2 (95% CI −0.66 to 0.91, Bonferroni-adjusted P = 1.00), and −0.22 mm2 (95% CI: −1.78 to 1.34, Bonferroni-adjusted P = 1.00), respectively, and remained consistent during the recovery period. Terrestrially, ONS distension is associated with increased ICP; therefore, these results suggest that, on average, ICP was not pathologically elevated immediately after spaceflight. However, a subject diagnosed with optic disc edema (Frisen Grade 1, right eye) displayed increased ONS area post flight, although this increase is relatively small compared to clinical populations with increased ICP. Advanced quantitative MRI-based assessment of the ON and ONS could help our understanding of SANS and the role of ICP.

Abstract The aim of this study was to analyze muscle regeneration after cryoinjury in the tibialis anterior muscle of young rats that were malnourished and then recovered. Forty Wistar rats were divided into a nourished group that received a normal protein diet (14% casein) for 90 days and a malnourished and recovered rats group (MR) that was submitted to 45 days of malnutrition with a hypoproteic diet (6% casein) followed by 45 days of a normal protein diet (14% casein). After the recovery period, all of the animals underwent cryoinjury in the right tibialis anterior muscle and euthanasia after 7, 14 and 21 days. The amount of connective tissue and the inflammation area was higher in the malnutrition recovered injury MR group (MRI) at 14 days post-injury (p < 0.05). Additionally, the cross-sectional area (CSA) of the regenerated fibers was decreased in the MRI (p < 0.05). The MyoD and myogenin protein levels were higher in the nourished injury group. Similar levels of TGF-β1 were found between groups. The proposed malnutrition protocol was effective in showing delayed changes in the regeneration process of the tibialis anterior muscle of young rats. Furthermore, we observed a delay in muscle repair even after nutritional recovery.

Background: The devastating 2014-2015 Ebola outbreak in Sierra Leone could erode the gains of the health system including the Community Health Worker (CHW) programme. We conducted a study to ascertain if the positive trend in reporting cases of malaria, pneumonia and diarrhoea treated by CHWs in the post-Ebola period has been sustained 18 months post-Ebola. Methods: We conducted a retrospective cross-sectional study using aggregated CHW programme data (2013-2017) from all Primary Health Units in Kenema district. Data was extracted from the District Health Information System and analysed using STATA. Data in the pre- (June 2013-April 2014), during- (June 2014-April 2015) and post-Ebola recovery (June 2016-April 2017) periods was compared and analysed for reporting completeness; Rapid Diagnostic Tests (RDTs) performed and cases of malaria, diarrhoea and pneumonia treated per month. Differences across periods were tested using two-sample t-test with significance set at 0.05. Results: CHW reporting increased from pre-Ebola by 8% (p-value=0.29) intra-Ebola and 19% (p-value=0.012) post-Ebola. Compared to the pre-Ebola period, in the post-Ebola recovery period, there was a significant increase in the mean monthly reported RDTs of 35% (p-value=0.020); malaria treatments 66% (p-value<0.001); and pneumonia treatments increased by 80% (p-value=0.004). Conversely, the mean monthly diarrhoea cases treated decreased by 20% (p-value=0.16) in the post-Ebola period. Conclusion: The resiliency demonstrated by the CHW programme during and immediately after the Ebola outbreak has been sustained in the post-Ebola recovery period. Continued programme investments in supportive supervision and financial incentives for CHWs will be critical to ensure uninterrupted contribution towards Sustainable Development Goal 3.

After the childbirth process, a mother is in the period after childbirth in which all of the genetalia have not been recovered as they were before the pregnancy. It requires much high nutrious foods with enough calory protein, fluid and fruits as well. But several factors in which one of them is from cultural aspect has influenced the changing of their attitude to abstain from eating. Obviously, this phenomenon can influence their health and recovery period after the childbirth indirectly. The object of this study is to find out the attitude of those mothers after the childbirth who abstain from eating in Ngebrak village, Subdistrict of Ringinrejo, Kediri Regency. The reseach design includes the cross sectional. The population is all mothers after childbirth who abstain from eating in Ngebrak village, Subdistrict of Ringinrejo, Kediri Regency. It is done toward the total sampling. The data is processed by analyzing the percentage. As the result, it is found out most respondents have three reasons to abstain of eating. There are 12 respondents (60%) and almost half of them have three kinds of prohibited meals. There are 7 respondents (35%) from the total of 20 respondents. The conclusion is most of those mothers after childbirth who abstain from eating is they do that because of beauty reason, cultural heredetary, elder people’s advice as well as their own belief and knowledge about abstaining as far as they know. Most avoided meals are animal protein. What would be better to do on this matter is by giving them information continously about commiting abstain from eating since it is still found nowdays. And most of them have more than a single reason to do that. Keywords: attitude, mother after childbirth, abstain from eating.

The Impact

The objective of this paper is to analyze the impact of economic policy uncertainty (EPU) in China, the United States, and Europe, which are influent to the Chinese stock markets. We employed Vector Autoregression (VAR) model with relative variables including the EPU indices and three Chinese stock markers indices to display the impulse responses of the markets to the EPUs. Our results indicate that the Chinese stock markets negatively respond to their domestic economic policy uncertainty in the first, second, and third month after the EPU shocks. Moreover, we also found the negative responses of the Chinese markets to the EPU from the United States that require five months to rebalance the markets. However, the Chinese markets seem positively respond to the shocks of the economic policy uncertainty in Europe and also took five months to archive market rebalancing. The significant correlation of the economic policy uncertainty between China and the United States resulted in cross-sectional correlation estimates among the EPU indices. Furthermore, there is the reasonable interesting result to claim that the economic policy uncertainty in China is statistically influenced by their own trade and fiscal policy uncertainty that may be considered to be related with China-US trade war in our conclusion.

Abstract Background: The World Health Organization (WHO) has declared the Corona pandemic as a public health emergency. This pandemic affects the main pillars of food security. This study aimed to investigate the relationship between food insecurity and the probability of hospitalization and the length of the recovery period after getting COVID-19.Methods: This cross-sectional study was performed through the census on COVID-19 patients diagnosed in Fasa, Iran. Informed consent, demographic, and food security questionnaire were completed over the phone. Then, all patients were followed up until recovery. Data were analyzed using SPSS26 and Chi-square test, t-test, and logistic regression (P> 0.05).Results: In this study, 219 COVID-19 patients [100 (54.7%) male and 119 female (54.3%)] with a mean age of 40.05±15.54 years old were examined. Possibility of hospitalization and the length of the recovery period of more than one month was significantly longer in the food insecure group (P = 0.001) and (P = 0.76), respectively, but the mean length of hospital stay in the two groups was not significantly different (P = 0.76). After adjusting for all confounding variables, people with food insecurity were 3.9 times more likely to be hospitalized than those with food security. Conclusions: We observed that food-insecure people were significantly more likely to be hospitalized than the secure group.
