Macro disagreement and the cross-section of stock returns

This paper examines the effects of macro-level disagreement on the cross-section of stock returns. Using forecast dispersion measures from the Survey of Professional Forecasters database as proxy for macro disagreement, I find that when disagreement about a macroeconomic factor is high, stocks that have high loadings on that macrofactor earn lower future returns relative to stocks with low loadings and vice versa. This negative relation between returns for macro-factors and macro-level disagreement is robust and exists for a large set of macroeconomic risk factors. These findings are consistent with the model of Hong and Sraer (2012), in which high beta stocks are more prone to speculative mispricing than low beta stocks due to their greater sensitivity to aggregate disagreement, resulting in lower subsequent returns for high beta stocks during high aggregate disagreement states.

Vulnerability and Resilience of Tropical Coastal Ecosystems to Ocean Acidification

Ocean acidification leads to a wide variety of responses from tropical coastal ecosystems. Coral reefs are most vulnerable with most coral species exhibiting declining calcification rates with decreasing pH and carbonate chemistry parameters. Some corals show resilience to acidification likely due to active physiological regulation of their calcifying fluid. Other calcifying organisms, such as some foraminifera and coccolithophores , exhibit negative responses, whereas some symbiont-bearing calcifiers respond positively, to increasing acidification. Seagrasses and brown macroalgae thrive under acidified conditions, with increasing rates of primary productivity. Some tropical coastal fish species are resilient, and in some species, respond positively, to acidification. Some tropical species show complex, nonlinear responses to declining pH and carbonate chemistry. Factors that influence the ability of a species to adapt to and/or resist acidification include food supply, nutrient availability, temperature, diet, interactions with symbionts and other organisms and species and community diversity. Interactive effects of ocean acidification with other climate change parameters, such as elevated temperature, play an important but poorly understood role in determining the resilience and vulnerability of tropical coastal species, communities and ecosystems. Some short-lived species can undergo acclimation and/or adaptive evolution to increase fitness in the face of acidification. Biota living in tropical estuarine and nearshore environments, such as mangroves, seagrasses and intertidal and subtidal inshore benthos, are unlikely to be significantly affected by future acidification as such environments exhibit very wide variations in water and sediment pH and carbonate chemistry. Nearly all tropical coastal environments exhibit significant CO 2 efflux to the atmosphere due to pCO 2 and [CO 32- ] oversaturation caused by high rates of respiration and factors linked to fluvial discharge. Except for coral reefs, most calcifying organisms and upwelling regions, tropical estuarine and inshore ecosystems unaffected by eutrophication and other anthropogenic problems should be resilient to future acidification.

Weak damping for the Korteweg-de Vries equation

For more than 20 years, the Korteweg-de Vries equation has been intensively explored from the mathematical point of view. Regarding control theory, when adding an internal force term in this equation, it is well known that the Korteweg-de Vries equation is exponentially stable in a bounded domain. In this work, we propose a weak forcing mechanism, with a lower cost than that already existing in the literature, to achieve the result of the global exponential stability to the Korteweg-de Vries equation.

Sea Surface Temperature in the South China Sea

Interannual variability of the sea surface temperature anomalies (SSTA) over the South China Sea (SCS) is recognized as an index for the Asian monsoon and ENSO system because of its special geographical location for that system. The following results are obtained by the statistical analysis of the observational data. (1) In the northern winter, the SCS SSTA are quite sensitive to the longitudinal shift of global wind anomalies associated with the equatorial Pacific SSTA. This fact is related to that the SCS SSTA and the neighbor SSTA have strong biennial oscillation. (2) When the global wind anomalies are shifted eastward in the winter (BO-type years), the tropical eastern Pacific SSTA tend to change in the following spring. On the other hand, when those wind anomalies are shifted westward (LF-type years), the eastern Pacific SSTA tend to be maintained through the year. The associated differences between the BO and LF-type years are found in the seasonal change of the low-level tropical wind anomalies from the preceding summer through winter. (3) The northern summer SCS SSTA seem to be controlled by in-situ low-level wind anomalies. Furthermore, easterly anomalies over South Asia and the tropical western Pacific and westerly anomalies over East Asia are found in the lower atmosphere for the positive SCS SSTA. It is also shown that the summer SCS SSTA have a statistical relationship with the equatorial central Pacific SSTA in the preceding winter. This fact suggests a relationship between the summer Asian monsoon and the winter phase of ENSO.
University of Birmingham Indocyanine green-mediated antimicrobial photodynamic therapy as an adjunct to periodontal therapy

Objectives The aim of this systematic review and meta-analysis was to evaluate the efficacy of indocyanine green – mediated photodynamic therapy (ICG-PDT) as an adjunct to non-surgical periodontal therapy (NSPT), in the management of chronic periodontitis. Materials and methods Four electronic databases (PubMed, Cochrane Central Register of Controlled Trials, Embase via OVID, Web of Science) were searched for randomised controlled trials comparing NSPT with ICG-PDT to NSPT without laser therapy. Primary outcome measures were changes in probing pocket depth (PPD) and clinical attachment level (CAL). Clinical outcomes were extracted and pooled from 7 eligible trials and meta-analyses conducted using mean difference with standard deviations. Results For PPD, adjunctive ICG-PDT resulted in a mean additional reduction of 1.17 mm (95% CI: 0.67 – 1.66 mm) at 3 months and a mean additional reduction of 1.06 mm (95% CI: 0.54 – 1.57 mm) at 6 months. For CAL, adjunctive ICG-PDT resulted in a mean additional gain of 0.70 mm (95% CI: 0.17 – 1.23 mm) at 3 months and a mean additional gain of 1.03 mm (95% CI: 0.83 – 1.24 mm) at 6 months. No adverse events were reported in any studies. Conclusions The adjunctive use of ICG-PDT in NSPT results in improved treatment outcomes at 3 and 6 months post-therapy. Further investigation is needed to evaluate variables such as different photosensitiser concentrations and adjusting parameters associated with the light source. Clinical relevance Indocyanine green – based photosensitisers may be a novel, clinically efficacious agent for use in the management of periodontitis.

The COVID-19 pandemic is a public emergency of international concern that affects several nations. The widespread outbreak of COVID19 virus has brought not only the risk of death but also major psychological pressure. However, the psychological impact on university students has not been studied in Ethiopia. Objective: To assess the psychological impacts of COVID-19 pandemic among university students in Bench-Sheko Zone, South-west, Ethiopia, 2020. Methods: A community-based cross-sectional study was conducted from May 15 to June 15/2020. A systematic sampling technique was employed to select the study participants. The data were entered into EpiData 3.1 and exported to SPSS version 24 for analysis. Bivariate and multivariable logistic regression were used to identify candidates and independent factors respectively. Independent factors of depression, anxiety, and stress were assessed using AORs with 95% confidence level at P-value <0.05 cut point. Results: Three hundred and twenty-two university students were included with a 97.5% response rate. The prevalence of depression, anxiety, and stress was 21.2%, 27.7%, and 32.5%, respectively. Being female, staying at home, history of medical illness, and poor and moderate social support increased the risk of depression. Not living with their parents, relatives got coronavirus and low family income were risk factors for anxiety. Moreover, substance use, depression, anxiety, and poor social support were increasing the risk of stress among university students. Conclusions and Recommendations: This study revealed a higher prevalence of depression, anxiety, and stress among university students. Thus, governments and policy makers should develop health system strategies to provide crisis-oriented psychological services for university students to minimize the mental health impact of the outbreak.
Salinity-triggered compositional and metabolic responses of autotrophic prokaryotes in Tibetan lacustrine sediments

fixation contributes approximately 50% of the global net primary production in aquatic ecosystems per year. Salinity is a prominent regulator structuring microbial communities in diverse aquatic ecosystems. However, little information is available regarding the compositional and physiological response of autotrophic microbial communities to salinity change. Here, we used genome-resolved metagenomics to study autotrophic microbial communities in 25 Tibetan lacustrine sediments with a salinity gradient (from 0.54‰ to 82.6‰). 117 metagenome-assembled genomes (MAGs) with carbon fixation potential belonging to 12 phyla were retrieved, of which approximately 21% were not affiliated with the known orders, suggesting taxonomically diverse autotrophic assemblages in sediments. The total abundance of these putative autotrophs decreased significantly with increasing salinity, and the variation of sediment autotrophic communities was mainly driven by salinity, pH and TOC. Notably, a change in the predominant lineage from Betaproteobacteria to Deltaproteobacteria was observed along the salinity gradient, and the dominant pathway for carbon fixation shifted from the Calvin-Benson-Bassham (CBB) cycle to more energy efficient Wood-Lungdahl (WL) pathway with glycolysis from Entner-Doudoroff to more exergonic Embden-Meyerhof-Parnas, demonstrating that the physiological efficiency increases from freshwater to hypersaline autotrophic communities. Metabolic inference revealed major links for carbon fixation to the oxidation of reduced sulfur compounds, ferrous iron and carbon monoxide, denitrification and nitrogen fixation in these MAGs, as well as the occurrence of dissimilatory sulfate reduction and the WL pathway dominating hypersaline sediments, greatly extending the understanding of metabolic versatility and diverse ecological niches of autotrophic microorganisms. This study provided a systematic attempt characterize the response of carbon fixation pathways to salinity and the knowledge essential for revealing ecological roles of autotrophic prokaryotes in
THE COMBINED USE OF SODIUM FLUORIDE AND ER: YAG LASER TO CONTROL THE PROGRESSION OF ENAMEL CARIES

This study aimed to evaluate in vitro the influence of the 0.05% NaF combined with Er:YAG laser irradiation to control dental enamel demineralization. Slabs of bovine enamel (3x3mm) were submitted to cariogenic challenges by pH-cycling method (5 days). After cycles, slabs were assigned into four groups, according to treatments (n=15): Placebo; Er:YAG Laser+Placebo; 0.05% NaF and Er:YAG Laser + 0.05% NaF. After surface treatment, new cariogenic challenges (14 days) were performed following the same protocol. The microhardness analysis was performed before caries formation and after cariogenic challenges. Data were submitted to analysis of variance (ANOVA) followed by DUNCAN test, at significance level of 1%. After cariogenic challenges, the placebo group (128.19 ± 6.68) presented the lowest microhardness values. The simultaneous action of Er:YAG laser + NaF (231.92 ± 22.81) promoted the highest values of enamel microhardness, followed by the treatments with Er:YAG laser (196.45 ± 33.76) and NaF (153.59 ± 14.80). The use of NaF combined with the Er: YAG laser may be an alternative to control the demineralization of enamel exposed to high cariogenic challenge.
Use of CFD to predict trapped gas excitation as source of vibration and noise in screw compressors

This paper investigates the source of noise in oil free screw compressors mounted on highway trucks and driven by a power take-off (PTO) transmission system. Trapped gas at the discharge side is suggested as possible source of the excitation of low frequency torsional resonance in these compressors that can lead to noise and vibration. Measurements and lumped mass torsional models have shown low frequency torsional resonance in the drive train of these compressors when they are mounted on trucks. This results in high torque peak at the compressor input shaft and in part to pulsating noise inside the machine. The severity of the torque peak depends on the amplitude of the input torque fluctuation from the drive (electric motor or truck engine). This in turn depends on the prop-shaft angle. However, the source of the excitation of this low torsional resonance inside the machine is unknown. Using CFD with mesh motion at every 1° rotation of the rotors, it is shown that the absence of a pressure equalizing chamber at the discharge can lead to trapped gas creation, which can lead to over-compression, over-heating of the rotors, and to high pressure pulsations at the discharge. Over-compression can lead to shock wave generation at the discharge plenum and the pulsation in pressure can lead to noise generation. In addition, if the frequency of the pressure pulsation in the low frequency range coincides with the first torsional frequency of the drive train the first torsional resonance mode can be excited.
From reactive to proactive: Czech examples of development and application of alternative road safety assessment approaches

Traditionally, road safety assessment has been based on accident history. However, this approach may be biased, since accident occurrence is statistically rare and partly random. In this regards, various alternatives have been sought worldwide. The paper presents two examples of development and practical application of alternative road safety assessment approaches in the Czech Republic. The first example describes accident prediction models, which were developed firstly for secondary roads in several regions and secondly for core road network (motorways and national roads), and used for identification of hazardous road locations. The second example describes a different proactive technique, using speed consistency in order to identify hazardous curves. The wider use of these approaches will enable shifting from traditional reactive accident-based approach to proactive alternatives, which will improve quality and efficiency of Czech road network safety management.
Mental Health of Mediums and Differential Diagnosis between Mediumship and Mental Disorders

—The issue of the mental state of mediums, and whether experiences considered mediumistic are symptoms of mental disorders, has long been subject to debate. Recent empirical studies may help to shed light on these controversies. As there are only a few studies on the mental health of mediums, ﬁ ndings regarding hallucination and dissociation in non-clinical populations are presented and discussed. Recent studies have not found an association between mediumship and mental disorders. Mediumistic experiences often occur in healthy and well-adjusted subjects. The occurrence of psychotic and/or dissociative experiences alone are not enough for a diagnosis of a mental disorder. It is essential to take into consideration the sociocultural context and the impact of these experiences on a patient’s life. In some cases, the emergence of mediumship may appear in the context of physical and mental symptoms, which poses a challenge for differential diagnosis. Further research is still necessary in order to discover enough elements to make a deﬁ nitive differential diagnosis between mediumship and mental disorders.
Tibetan sheep are better able to cope with low energy intake than Small-tailed Han sheep due to lower maintenance energy requirements and higher nutrient digestibilities

breeds. Sheep of each breed (n=24 of each, all wethers and 1.5 years of age) were distributed randomly into one of four groups and o ﬀ ered ad libitum diets of di ﬀ erent digestible energy (DE) densities: 8.21, 9.33, 10.45 and 11.57MJ DE/ kg Dry matter (DM). Following 42 d of measuring feed intake, a 1-week digestion and metabolism experiment was done. DM intakes did not di ﬀ er between breeds nor among treatments but, by design, DE intake increased linearly in both breeds as dietary energy level increased ( P <0.001). The average daily gain (ADG) was signi ﬁ cantly greater in the Tibetan than Small-tailed Han sheep ( P = 0.003) and increased linearly in both breeds ( P <0.001). In addition, from the re- gression analysis of ADG on DE intake, daily DE maintenance requirements were lower for Tibetan than for Small-tailed Han sheep (0.41 vs 0.50MJ/BW 0.75 , P <0.05). The DE and me- tabolizable energy (ME) digestibilities were higher in the Tibetan than Small-tailed Han sheep ( P <0.001) and increased linearly as the energy level increased in the diet ( P <0.001). At the lowest energy treatment, Tibetan sheep when compared with Small-tailed Han sheep, had: 1) higher serum glucose and glucagon, but lower insulin concentrations ( P <0.05), which indicated a higher capacity for gluconeogenesis and ability to regulate glucose metabolism; and 2) higher non-esteri ﬁ ed fatty acids (NEFA) and lower very low density lipoprotein (VLDL) and triglyceride (TG) concentrations ( P <0.05), which indicated a higher capacity for NEFA oxidation but lower ability for triglyceride (TG) synthesis. We concluded that our prediction was supported as these di ﬀ erences between breeds conferred an advantage for Tibetan over Small-tailed Han sheep to cope better with low energy diets.
Promoting Human Valuesthrough High School Curriculum: A Study into Discourse Features of Pakistani ELT Textbooks

This study focuses on textbooks‟ embedded themes about human values in secondary level ELT textbooks of Pakistan, namely Baluchistan Textbook Board (BTB) Quetta, Sindh Textbook Board (STB) Jamshoro, Khyber Pakhtunkhwah Textbook Board (KTB) Peshawar and Punjab Textbook Board (PTB) Lahore. To accomplish the objectives, the study is delineated into two distinct parts: in part one human values related textbook contents have been identified and analyzed by using Fairclough‟s (1995) three-dimensional framework augmented by Van dijk‟s (2006) socio-cognitive approach. The second part of the study is dedicated to obtaining readership‟s conceptions related to human values through questionnaire-based survey all over the country. The study reveals an adequate inclusion of human-values related themes in all four ELT textbooks. The findings of part 2 indicate that human values related to tolerance and equality are adequately present in readership‟s minds. In contrast, virtues such as honesty and patience are found lacking among young males and females. The research recommends a human values-based test of all textbooks at the national level before publication to ensure improved human values related contents in the syllabus as directed in National Curriculum of Pakistan.
ISW measurements with photometric redshift surveys: 2MASS results and future prospects

In a ﬂat universe dominated by dark energy, the Integrated Sachs-Wolfe (ISW) eﬀect can be detected as a large-angle cross-correlation between the CMB and a tracer of large scale structure. We investigate whether the inconclusive ISW signal derived from 2MASS galaxy maps can be improved upon by including photometric redshifts for the 2MASS galaxies. These redshifts are derived by matching the 2MASS data with optical catalogues generated from SuperCOSMOS scans of major photographic sky surveys. We ﬁnd no signiﬁcant ISW signal in this analysis; an ISW eﬀect of the form expected in a ΛCDM universe is only weakly preferred over no correlation, with a likelihood ratio of 1.5:1. We consider ISW detection prospects for future large scale structure surveys with fainter magnitude limits and greater survey depth; even with the best possible data, the ISW cross-correlation signal would be expected to evade detection in & 10% of cases.
