Coronavirus Plunges the German Economy into Recession: DIW Economic Outlook

The spread of the coronavirus worldwide is exerting considerable pressure on the economy. Compounded by the lack of quality data, model uncertainty, and uncertainty over government responses, economic forecasts are subject to even greater uncertainty than usual. It is difficult to predict how the pandemic will progress. Figures on the impact of the virus, obtained by comparing it with previous epidemics, for example, provide rough approximations at best. Based on the model calculations, Germany can expect to suffer huge economic losses. Given the information available, it is reasonable to assume that economic output will actually be one percentage point lower than recently projected in the winter outlook. As a result, GDP will decline by 0.1 percent this year. If the higher number of working days this year is factored in, in line with general international practice, economic output will fall by as much as 0.5 percent. The corona pandemic will plunge Germany into recession, albeit the exact size of the downturn remains unclear.
A Constrained Multiobjective Evolutionary Algorithm With Detect-and-Escape Strategy

Overall constraint violation functions are commonly used in multiobjective evolutionary algorithms (MOEAs) for handling constraints. Constraints could cause these algorithms stuck in two stagnation states: 1) since the feasible region of a multiobjective optimization problem can consist of several disconnected feasible subregions, the search can be easily trapped in a feasible subregion which does not contain all the global Pareto optimal solutions and 2) an overall constraint violation function may have many nonzero minimal points, it can make the search stuck in an unfeasible area. To address these two issues, this article proposes a strategy to detect whether or not the search is stuck in these two stagnation states and then escape from them. Our proposed detect-and-escape strategy uses the feasible ratio and the change rate of overall constraint violation to detect stagnation, and adjusts the weight of the constraint violation for guiding the search to escape from stagnation states. We develop and implement a decomposition-based constrained MOEA with this strategy. Extensive experiments on a number of benchmark problems demonstrate the competitiveness of our proposed algorithm when compared to five other state-of-the-art constrained evolutionary algorithms.

FIRST REPORT ON THE OCCURRENCE OF TOBACCO STREAK VIRUS IN SUNFLOWER IN IRAN

Sunflower (Helianthus annuus), an important oilseed crop grown in Iran and many other countries, is a frequent host of Tobacco streak virus (TSV, genus Ilarvirus), which infects a wide range of crops and weeds. To study the occurrence and distribution of TSV in Iran, 1,272 samples were collected from sunflower fields in Kerman, Golestan, Isfahan, Mazandaran, Qom, Azarbayejan-Gharbi, Markazi, Hamedan and Tehran provinces during 2006 to 2008. TSV was detected by DAS-ELISA in 20.9% of the samples. The characterization of two Iranian virus isolates 43R (from Tehran) and IR (from Isfahan) showed that both have isometric particles 26 to 35 nm in diameter, and coat protein (CP) subunits with a molecular weight of 30.9 kDa. In mechanical inoculation assays, the Iranian TSV isolate induced local lesions on a number of plant species of the families Chenopodiaceae and Solanaceae. Vicia faba and sunflower reacted with systemic symptoms. A fragment of 747 nt in length from the CP gene of each isolate was amplified, cloned and sequenced. BLAST analysis of the CP sequences showed that both isolates are similar to Sudanese TSV isolates and belong to the same group. This is the first report on the detection of TSV in Iran.
The Characteristics of Literacy Management in School Literacy Movement (SLM) at Junior High School in Malang - Indonesia

This study aims to evaluate the implementation of the school literacy movement (SLM) program in junior high schools in Malang, East Java, Indonesia. The evaluation includes three stages of SLM: the stage of habituation, development, and learning. This study was an evaluative study using the CIPP model (context, input, process, and product) and used a qualitative descriptive approach. The sample unit consisted of 12 schools, with a category of nine public schools and three private schools. The schools were selected using a purposive random sampling technique. The research sample consisted of teachers, principals, and education personnel. Methods of data collection through observation, interviews, and examination of program implementation documents. Data analysis uses the Miles and Huberman model which consists of data reduction, data display, and conclusion drawing, while the formulation of strategic steps uses the calculation of internal strategic factors (IFAS) and external strategic factors (EFAS). The results showed that the implementation of new literacy at the habituation and development stage had not yet reached the learning stage. However, IFAS and EFAS values are 3.34 and 3.39, respectively. These results indicate that the development of the literacy program still has many weaknesses (<5.00) and needs intensive efforts in order to increase student literacy.
Meta-Analysis of Prompt and Duration for Curriculum-Based Measurement of Written Language

ABSTRACT Researchers studying curriculum-based measurement of written expression have used a variety of writing prompt types and durations when establishing criterion validity of these tools. The purpose of this study was to determine through meta-analytic procedures whether any prompt type or duration was superior to others in terms of criterion validity. The literature search returned 24 articles (N = 24) that met our inclusion criteria. Included studies examined criterion validity for a variety of prompts: picture, story starters, expository, text copying, picture-word, and picture-story. These studies also reported criterion validity for writing durations ranging from 1.5 to 10 minutes. Results indicated no clear trends in criterion validity for prompt or duration. We provide suggestions for practitioners considering the use of CBM in written expression.
Joint Governance Regions and Major Prevention Periods of PM2.5 Pollution in China Based on Wavelet Analysis and Concentration-Weighted Trajectory

China has made some progress in controlling PM2.5 (particulate matter with an aerodynamic diameter of ≤2.5 μm) pollution, but there are still some key areas that need further strengthening. Considering that excessive prevention and control efforts affect economic development, this paper combined an empirical orthogonal function, a continuous wavelet transform, and a concentration-weighted trajectory method to study joint regional governance during key pollution periods to provide suggestions for the efficient control of PM2.5. The results from our panel of data of PM2.5 in China from 2016 to 2018 could be decomposed into two modes. In the first mode, the pollution center was in central Shaanxi Province, and the main eruption period was from November to January of the following year. As the center of this region, Xi’an should cooperate with the four cities in eastern Sichuan (Nanchong, Guangan, Bazhong, and Dazhou) to control PM2.5, since the eruption occurred in this area. Moreover, governance should last for at least two cycles, where one cycle is at least 23 days. The pollution center of the second mode was in the western part of Xinjiang. Therefore, after the prevention and control efforts during the first mode are completed, the regional city of Kashgar should continue to build a joint governance zone for PM2.5 along the Tianshan mountains in the east, focusing on prevention and control over two cycles (where one cycle is 28 days).
The Permian–Triassic boundary in continental sedimentary succession at the SE margin of the Central European Basin (Holy Cross Mountains, Poland)

Abstract We studied the upper Permian and Lower Triassic deposits from the northern and northwestern marginal part of the Holy Cross Mountains (SE part of the Central European Basin or CEB, Poland) to examine stratigraphic continuity between these two systems, and to revise the currently existing stratigraphic framework. A previously existing informal lithostratigraphic scheme has been revisited and placed in a broader chronostratigraphic and palaeoenvironmental context. Sedimentary continuity across the Permian–Triassic (P/T) boundary has been confirmed by the presence of Lueckisporites virkkiae Bc morphological norm and Lundbladispora obsoleta–Protohaploxypinus pantii palynomorphs. Facies development reflects an interplay between climatic variations and tectonism during late Permian – Early Triassic time. The P/T boundary was placed between the Siodła Formation and overlying Szczukowice and Jaworzna formations, which coincides with the classical Zechstein–Buntsandstein boundary in the SE part of the CEB. The facies changes recorded in the studied terrestrial succession of the P/T boundary shed light on the environmental dynamic prior, during and after one of the biggest biotic crises in Earth’s history.
Glyoxal's impact on dry ammonium salts: fast and reversible surface aerosol browning

Abstract. Alpha-dicarbonyl compounds are believed to form brown carbon in the atmosphere via reactions with ammonium sulfate (AS) in cloud droplets and aqueous aerosol particles. In this work, brown carbon formation in AS and other aerosol particles was quantified as a function of relative humidity (RH) during exposure to gas-phase glyoxal (GX) in chamber experiments. Under dry conditions (RH < 5 %), solid AS, AS–glycine, and methylammonium sulfate (MeAS) aerosol particles brown within minutes upon exposure to GX, while sodium sulfate particles do not. When GX concentrations decline, browning goes away, demonstrating that this dry browning process is reversible. Declines in aerosol albedo are found to be a function of [GX]2 and are consistent between AS and AS–glycine aerosol. Dry methylammonium sulfate aerosol browns 4 times more than dry AS aerosol, but deliquesced AS aerosol browns much less than dry AS aerosol. Optical measurements at 405, 450, and 530 nm provide an estimated Ångstrom absorbance coefficient of -16±4. This coefficient and the empirical relationship between GX and albedo are used to estimate an upper limit to global radiative forcing by brown carbon formed by 70 ppt GX reacting with AS (+7.6×10-5 W m−2). This quantity is < 1 % of the total radiative forcing by secondary brown carbon but occurs almost entirely in the ultraviolet range.
The chloroplast genome of Gardenia jasminoides and related phylogenetic analysis (Rubiaceae)

Abstract Gardenia jasminoides is well distributed and planted in China because of high ornamental and medical applications in Rubiaceae. Therefore, aiming at studying the biodiversity and solar-related genes, we acquired its complete chloroplast genome. The chloroplast genome was 155,096 bp in length with typical circle structure, it presented an 85,409 bp large single-copy (LSC) region, an 18,103 bp small single-copy (SSC) region, and two 25,792 bp inverted repeat (IRs) regions. The overall GC content was 37.49%, SSC and IR components showed extreme GC percentages ranging from 31.53 to 43.18. A brief online annotation reported 125 CDSs, 8 rRNAs, and 33 tRNA. To our surprise, G. jasminoides was closer to Coffea canephora and Coffea arabica within Rubiaceae from phylogenetic analysis. This chloroplast genome announcement of the G. jasminoides could embody light on the artificial breeding and further researches in the genus Gardenia Ellis and recruit more studies in this family.

Affordance-based view of the effects of self-service technology interactions on post-purchase behavioral intention

Purpose- The purpose of this study is to explore the influence of SST interaction experiences on service quality, consumer satisfaction, and the subsequent behavioral intentions of electronic word-of-mouth and repurchase. Methodology- The research design adopts the convenience sampling method to survey consumers of an SST hotel located in central Taiwan, utilizing an on-site questionnaire upon checkout. Findings- Findings indicate that interaction experiences, such as functional affordance and cognitive affordance, have a positive effect on SST's service quality and satisfaction. Customers with an excellent evaluation of SST service quality are more likely to be satisfied with SST and more willing to recommend or choose the same service in the future. Results also suggest that perceived self-control has a moderating effect on the relationship between cognitive affordance and SST service quality and satisfaction with SST. Conclusion- This study develops a new model of the self-service technology (SST) interaction experience. This new model fills a research gap by providing an empirical study of the repeated use and commitment phases of the SST adoption model grounded in innovation diffusion theory.
Performance Appraisal as an Antecedent to Innovation: an Analysis of Its Relative Importance

Literature suggests that performance appraisal (PA) contributes to innovation. However, the absolute and relative importance of PA to innovation, the different aspects of PA which drive innovation, as well as PA as a precursor among other antecedents to innovation, has not been adequately described. The aim of the study is to provide clarity on the drivers of innovation, specifically contextualising the impact of PA within the South African context. This study used a cross-sectional survey design, where only quantitative data was collected from full-time employees across private sector, parastatal, and government organisations. The respondents represented a broad cross-section of South African employees. PA and three other known antecedents to innovation, as well as innovation itself, were measured. It was found that PA (as a single variable) was responsible for 5.7% of the variance in innovation. Items in the PA scale with a clear link to innovation were identified, and thematically integrated. It was further found that, when PA was combined with other antecedents of innovation, leading to 26.6% of the variance in innovation being explained, the role of PA was significant, though mostly secondary. Proactive personality was the most dominant predictor of innovation. The importance and relative importance of PA as an antecedent to innovation in the workplace has thus been established. The outcomes of this study may assist managers and human resource practitioners to focus on appropriate, evidence-based information when attempting to enhance innovation.
Bayes-Optimal MMSE Detector for Massive MIMO Relaying With Low-Precision ADCs/DACs

In this study, we focus on the detector design for a massive multiple-input multiple-output amplify-and-forward relaying system with low-precision analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). A general relaying model with direct and relay links is considered. Several studies have been performed on the basis of simple but performance-limited linear transceivers. The optimal detector for the aforementioned setting remains unknown. To bridge this gap, we develop a minimum mean squared error detector based on the framework of variational Bayes inference. The proposed detector works similarly to the iterative turbo update, and the extrinsic information of the direct and relay links are updated through maximum ratio combining. Furthermore, our algorithm uses a partially parallel update schedule that improves the convergence compared with an intuitive method that is based on a fully parallel schedule. We then present the state evolution (SE) as an analytical framework to investigate the mean squared error and symbol error rate of the detector. By specifying the dynamics of the SE, we reveal that low-precision ADCs/DACs, that is, those using 2-4-bit quantization, realize a good tradeoff between performance and cost. Moreover, low-precision ADCs/DACs provide numerous insights into the relaying system and its design, such as the quantization step size.
THE INFLUENCE OF FEED PROTEIN AND ENERGY LEVEL ON MEAT CHEMICAL COMPOSITION AT "HYBRO PN + " BROILER CHICKENS

In this paper was studied the influence of feed energy-protein level on meat chemical composition depending on: sex and anatomical region for chicken broiler belonging „Hybro Pn + ” hybrid, slaughtered at 42 days old. The two groups (control group-Lc and experimental groups-Lexp) were given feed mixed with different level of energy and protein (Lc-standard hybrid, Lexp-higher by 10% compared to standard hybrid). After slaughter, from each group were sampled 10 carcasses (five females and five males), and from different portions of the carcass (breast, thighs and shanks), was determined the meat chemical composition (water, dry matter, protein, lipids and minerals) using STAS methods. For analysis of variance were used Mann Whitney test. For males the pectoral muscle had a greater amount of dry matter, compared with females, the situation is reversed when has referring to the muscles of the thighs and shanks. The lipids content in meat showed the biggest variation between muscles analyzed, with minimum values in the pectoral muscles (from 0.91% at males-Lexp up to 1.13% in females-Lc) and maximum values in the upper thigh muscles (from 6.98% in males-Lexp up to 7.94% in females-Lc). At the Lexp group, the feed with higher protein-energy level has lead to increases of the protein content and decreased lipids content of meat.
The International Market for Corporate Control

This paper documents a set of stylized facts about recent trends in cross-border MA (ii) how it varies across industries and locations; (iii) how it compares to levels of greenfield FDI over time; (iv) horizontal (market access) versus vertical (integrating supply chains) transactions; (v) the mode of financing; (vi) diversifying transactions versus those in the same industry; (vii) patterns of control acquisition; and (viii) strategic versus financially motivated transactions. The paper also examines whether the nature of cross-border M&A activity differs across developed and emerging markets. Next, it considers the incentives for firms to buy firms in other countries and to sell divisions to foreign buyers and examines the evidence about post-acquisition outcomes. The paper concludes with a discussion of policy challenges that confront governments as they weigh the balance of national security concerns against a desire to increase foreign investment in their economies.
Exercise and fluid challenge during right heart catheterisation for evaluation of dyspnoea

This prospective study compared exercise test and intravenous fluid challenge in a single right heart catheter procedure to detect latent diastolic heart failure in patients with echocardiographic heart failure with preserved ejection function. We included 49 patients (73% female) with heart failure with preserved ejection function and pulmonary artery wedge pressure ≤15 mmHg. A subgroup of 26 patients had precapillary pulmonary hypertension. Invasive haemodynamic and gas exchange parameters were measured at rest, 45° upright position, during exercise, after complete haemodynamic and respiratory recovery in lying position, and after rapid infusion of 500 mL isotonic solution. Most haemodynamic parameters increased at both exercise and intravenous fluid challenge, with the higher increase at exercise. Pulmonary vascular resistance decreased by –0.21 wood units at exercise and –0.56 wood units at intravenous fluid challenge (p = 0.3); 20% (10 of 49) of patients had an increase in pulmonary artery wedge pressure above the upper limit of 20 mmHg at exercise, and 20% above the respective limit of 18 mmHg after intravenous fluid challenge. However, only three patients exceeded the upper limit of pulmonary artery wedge pressure in both tests, i.e. seven patients only at exercise and seven other patients only after intravenous fluid challenge. In the subgroup of pulmonary hypertension patients, only two patients exceeded pulmonary artery wedge pressure limits in both tests, further five patients at exercise and four patients after intravenous fluid challenge. A sequential protocol in the same patient showed a significantly higher increase in haemodynamic parameters at exercise compared to intravenous fluid challenge. Both methods can unmask diastolic dysfunction at right heart catheter procedure, but in different patient groups.
Experimental investigation and modeling of the viscosity of some water-based nanofluids

Abstract The kinematic viscosity of three kinds of nanofluids namely Al2O3/water, TiO2/water, and graphene/water was measured at different temperatures. Concentration of the metallic oxide nanoparticles in water ranged from 0.01 to 0.04 wt% with 0.01 wt% steps while the concentrations of graphene/water nanofluids were 0.05, 0.25, 0.5, 0.75, 1 wt%. The viscosity of the studied nanofluids was measured at five temperatures ranging from 25 to 65 °C with 10 °C steps. The viscosity of DI water was measured at these temperatures as well. The viscosity ratios of all the studied nanofluids were calculated and compared with the prediction of nine well-known models proposed by former researchers. The percent error of these models in predicting the viscosity ratio of the studied nanofluids varied between 1.13% and 19.51% for Al2O3/water; 0.01% and 21.94% for TiO2/water, and 0.14% and 68.78% for graphene/water nanofluid. Polynomial models were proposed for each nanofluid as these had lower percent errors in calculating viscosity ratios. The percent errors of the proposed models were 0.06 − 5.36% for Al2O3/water; 0.12 − 3.35% for TiO2/water, and 0.15 − 55.74% for graphene/water nanofluid. Two overall models were also proposed for the viscosity ratio of all the studied nanofluids, one of which was temperature independent while the other had a functionality of temperature. The percent errors of the overall proposed models were observed to vary from 0.1% to 49.21% and from 0.02% to 36.83%, respectively which shows higher level of accuracy in predicting the viscosity ratio of the studied nanofluids when compared with the previous models.
