A Multilevel Study of Group Affective Tone and Team Innovation: A Moderated Mediation Model

Drawing on broaden-and-build theory and threat-rigidity hypothesis, we theorized and tested a multilevel model to examine the moderating effects of transformational leadership (TFL) on the team-level process that links positive/negative group affective tone (PGAT/NGAT) to team innovation via information elaboration. Data were collected from 299 team members and 65 leaders from Taiwanese companies at two time points. The multilevel path analysis demonstrated support for a positive indirect effect of PGAT on team innovation via information elaboration and a negative indirect effect of NGAT on team innovation via information elaboration. The positive indirect effect of PGAT on team innovation via information elaboration was found to be stronger when TFL was high rather than low. However, TFL did not attenuate the negative effects of NGAT. Negative group affective tone was negatively related to information elaboration when TFL was high, whereas NGAT had no significant relationship with information elaboration when TFL was low. Theoretical and practical implications are discussed.
Full stomachs at empty tides: tidal cycle affects feeding activity and diet of the sandy beach gastropod Olivella minuta

Olivella minuta is an abundant neogastropod on sandy beaches from Texas (USA) to southern Brazil. This study aimed to characterize and compare the feeding activity and diet of a Brazilian population of O. minuta in different tidal zones (intertidal and subtidal), and different tidal levels (high and low tides), with three combinations of tidal zone and level being studied (intertidal during low tide, intertidal during high tide and subtidal). The results showed that diet composition was generally similar among tidal conditions, with O. minuta being a generalist, feeding on 45 different food items. Feeding activity, however, was higher in the intertidal during low tide, whereas the richness and diversity of food items were higher in the intertidal during high tide. The higher feeding activity of O. minuta during low tide may be linked to a lower risk of predation; at low tide organisms may be able to feed for a longer time, and this may be particularly true on beaches with fine sand, where water retention is higher than that on beaches with coarse sand. The higher diversity of food items consumed in the intertidal during high tide is likely related to the increased prevalence of planktonic food during high tide. Our results indicate that tidal zone and level may strongly influence the feeding activity of coastal soft-bottom species and that species may show higher feeding activity during low tide. Given the current loss of intertidal habitats due to anthropogenic activity and climate-change associated factors, our study has important implications, highlighting the importance of intertidal areas for the ecology and conservation of sandy beach species.
Electroplating Method on Copper (Cu) Substrate with Silver (Ag) Coating Applied

Knowing about metal coating (electroplating) is the electrodeposition of coatings or coatings attached to the electrodes to protect the substrate by giving surface properties and dimensions different from the base metal or finishing technique, by coating metal that is easily corroded (corrosion) with metals that are resistant to corrosion with electrical and chemical engineering. Whereas in Indonesian society the technique for metal coating is very familiar with the name of the gilding technique. In ancient times before electroplating and gilding were discovered to avoid corrosion of metals, the incorporation of metals such as copper with tin into bronze, copper with zinc into brass in addition to being resistant to corrosion also added to the beauty of color. Among the alloys above bronze is the oldest alloys that have been used by humans. With the development of the times, more modern gilding techniques were found to be a more practical method, namely electroplating, gilding with electrical and chemical processes that make metals resistant to corrosion. Metal coating is a scientific field which is one of the applications of electro chemical technology. Very closely related to the material science and technology, surface chemistry, physical chemistry, to the engineering. Various metals can be plating. The various metals are classified into five groups: "tumbal" coatings, decorative-protective coatings, engineered metal coatings, rare-use metals, and various types of alloys. All of these have their own characteristics, both advantages and disadvantages.
The International Dimensions of Macroprudential Policies

The large economic costs associated with the Global Financial Crisis have generated renewed interest in macroprudential policies and their international coordination. Based on a core-periphery model that emphasizes the role of international financial centers, we study the effects of coordinated and non-coordinated macroprudential policies when financial intermediation is subject to frictions. We find that even when the only frictions in the economy consist of financial frictions and financial dependency of periphery banks, the policy prescriptions under international policy coordination can differ quite markedly from those emerging from self-oriented policy decisions. Optimal macroprudential policies must address both short run and long run inefficiencies. In the short run, the policy instruments need to be adjusted to mitigate the adverse consequences of the financial accelerator, and its cross-country spillovers. In the long run, policymakers need to take into account the effects of the higher cost of capital, due to the presence of financial frictions. The gains from cooperation appear to be sizable. Nevertheless, their magnitude could be asymmetric, pointing to potential political-economy obstacles to the implementation of cooperative measures.
Incidence of Pseudoprogression during Immune Checkpoint Inhibitor Therapy for Solid Tumors: A Systematic Review and Meta-Analysis.

BackgroundImmune checkpoint inhibitors (ICIs) have been increasingly used in cancer treatment, and a subset of patients undergo pseudoprogression. Recognizing the incidence of pseudoprogression is critical for clinical practice.PurposeTo evaluate by systematic review and meta-analysis the incidence of pseudoprogression in cancer treatment with ICIs, and compare the incidence according to response criteria, tumor types, and immunotherapeutic agents.Materials and MethodsMedline and Embase were searched to identify relevant studies published before December 31, 2018. Clinical trials, post hoc analysis of clinical trials, and prospective studies on ICI treatment in patients with malignant solid tumors were included. Pooled incidence of pseudoprogression for all included studies, per definition of pseudoprogression, cancer type, and drug type, was obtained by random-effects models with inverse variance weighting model.ResultsSeventeen studies with 3402 patients were analyzed. The pooled incidence of pseudoprogression was 6.0% (95% confidence interval: 5.0%, 7.0%). The definition of pseudoprogression were divided into four categories: progressive disease followed by partial response (PR) or complete response (CR) but not stable disease (SD) with Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (six studies); progressive disease followed by SD or PR or CR with RECIST 1.1 (five studies); progressive disease followed by SD or PR or CR with RECIST 1.0 (three studies); and progressive disease followed by SD or PR or CR with immune-related response criteria (irRC) (three studies). Incidence of pseudoprogression varied from 4.5% to 8.0% per definition, ranged from 5.0% to 7.0% per cancer type, and was 5.6% with the monotherapy of programmed cell death-1 inhibitor.ConclusionThe overall incidence of pseudoprogression was 6.0% and was less than 10% in subgroup analyses according to the definitions of pseudoprogression, cancer type, and immune checkpoint inhibitor type. Varying definitions across trials and studies indicates the need for uniform criteria of pseudoprogression for solid tumors. © RSNA, 2020Online supplemental material is available for this article.See also the article by Dodd and MacDermott in this issue.

Dying to serve: the mass burials at Kerma

High ranking burial mounds in Bronze Age Sudan featured burials in a corridor leading to the central burial – supposedly of a king. Were the ‘corridor people’ prisoners captured during periodic raids on Egypt, or local retainers who followed their king in death? The authors use the skeletal material to argue the second hypothesis – coincidentally that advanced by George Reisner, the original excavator.
Customizable and scalable automated assessment of C/C++ programming assignments

The correction of exercises in programming courses is a laborious task that has traditionally been performed in a manual way. This situation, in turn, delays the access by students to feedback that can contribute significantly to their training as future professionals. Over the years, several approaches have been proposed to automate the assessment of students' programs. Static analysis is a known technique that can partially simulate the process of manual code review performed by lecturers. As such, it is a plausible option to assess whether students' solutions meet the requirements imposed on the assignments. However, implementing a personalized analysis beyond the rules included in existing tools may be a complex task for the lecturer without a mechanism that guides the work. In this paper, we present a method to provide automated and specific feedback to immediately inform students about their mistakes in programming courses. To that end, we developed the CAC++ library, which enables constructing tailored static analysis programs for C/C++ practices. The library allows for great flexibility and personalization of verifications to adjust them to each particular task, overcoming the limitations of most of the existing assessment tools. Our approach to providing specific feedback has been evaluated for a period of three academic years in a course related to object‐oriented programming. The library allowed lecturers to reduce the size of the static analysis programs developed for this course. During this period, the academic results improved and undergraduates positively valued the aid offered when undertaking the implementation of assignments.
Red Sea , Egypt

Isotopes of uranium in the sea-water sediments collected from two different areas (El Hamraween harbour and Ras El Behar) on the Egyptian coast of the red sea have been studied using radiochemical separation procedures and alpha-particle spectrometry. Activity concentrations of 238U, 235U, 234U were calculated. The activities observed indicated enhanced radioactivity levels in sea-water sediments of El Hamraween harbour area due to the activities of phosphate shipment operation. Secular equilibrium between 234U and 238U was found in the analyzed samples. The average activity ratio of 235U/238U was close to the value 0.046 for uranium in nature. 2009 Elsevier Ltd.

The Framing of Russian Military Involvement in the Syrian Civil War on Sputnik Media

The legitimacy of a country’s foreign policy is often determined by how the media report on the country’s political activity outside that country. The country's involvement in a conflict or war and the reason for engaging needs to be communicated to the public globally with a mediaframing strategically. This article aims to explore the framing of the Russian military's involvement in the Syrian civil war by the online media outlet Sputnik. The researchers employed a qualitative content analysis method on 238 articles published by Sputnik between February and September 2016. During this period Russia and the United States, as two external powers involved in the Syrian civil war, agreed on a ceasefire. This development represented a strategic moment for Russia to communicate the activities of its military in Syria by using a framing strategy in Sputnik. This research revealed that Sputnik actively used framing to legitimize the Russian military's involvement in the Syrian civil war. Specifically, the media outlet used the frames of responsibility, morality, and conflict to attract public attention and to shape their perspectives about the Russian military's involvement in the Syrian civil war as necessary and positive. The findings indicate that, at Sputnik, framing constituted an attempt to form a positive image of Russia as a strong state to the international world through news related to the involvement of the Russian military in Syria's civil war.

Diversity of diatoms, benthic macroinvertebrates, and fish varies in response to different environmental correlates in Arctic rivers across North America

1. Climate change poses a significant threat to Arctic freshwater biodiversity, but impacts depend upon the strength of organism response to climate-related drivers. Currently, there is insufficient knowledge about Arctic freshwater biodiversity patterns to guide assessment, prediction, and management of biodiversity change. 2. As part of the Circumpolar Biodiversity Monitoring Program’s first freshwater assessment, we evaluated diversity of diatoms, benthic macroinvertebrates, and fish in North American Arctic rivers. Alpha diversity was assessed in relation to temperature, water chemistry, bedrock geology, and glaciation history to identify important environmental correlates. Biotic composition was compared among groups to evaluate response to environmental gradients. 3. Macroinvertebrate alpha diversity declined strongly with increasing latitude from 48°N to 82°N, whereas diatom and fish diversity peaked around 70°N without a clear latitudinal decline. Macroinvertebrate diversity was significantly positively related to air temperature. Diatom diversity was related to bedrock geology and temperature, whereas fish diversity was related to glaciation history. 4. Fish and macroinvertebrate assemblages differed between sites in western Canada, where invertebrate composition was more variable, and Alaska, where fish composition was more variable. In sites with both diatom and macroinvertebrate data, diatom composition was distinct in Alaska, where richness was highest in former glacial refugia. Macroinvertebrate composition was distinct in lowest-latitude eastern and high-latitude western Canadian sites where temperature was warmest. 5. Temperature, precipitation, geology, calcium, and substrate size were important environmental correlates for diatoms and macroinvertebrates, though the relative importance of each correlate differed. Diatom taxa were most strongly associated with water chemistry, whereas benthic invertebrate composition related most strongly to precipitation and temperature. 6. This large-scale study provides the most substantial integration and analysis of river diatom, macroinvertebrate, and fish data from the North American Arctic to date. Findings suggest that macroinvertebrates will show the strongest response to climate-related shifts in temperature, whereas diatoms and fish are more likely to respond to climate-induced shifts in nutrients and hydraulic connectivity. However, significant gaps in data coverage limited our ability to reliably evaluate spatial patterns and detect change. These gaps could be reduced by improving collaborative efforts between the U.S.A. and Canada to harmonize future monitoring.
Financial Convergence on Emerging Markets: The Case of CEE Countries

This paper investigates information embedded in the most liquid derivative instruments regarding the scope of convergence reported on the financial market in the emerging CEE countries. We present a proposal of the index that measures the scale of convergence between local and global derivative prices. The financial convergence index (FCI) encompasses a basket of prices that are remarkable for evaluation of the current state of converging economies. The study covers OTC foreign exchange and interest rate markets, as these segments are the most liquid areas of emerging markets. Moreover, we analyse the connection between derivatives pricing and broad market equity indices. The index provides evidence of a divergence process observed in the course of the financial crisis and presents a similar pattern to equity benchmarks.
Three Phase Nine Level Inverter Fed Induction Motor Drives for Harmonic Reduction

The main aim of this project is three phase nine level inverter fed induction motor drives for harmonic reduction in existing system The four-switch three-phase (B4) inverter, having a lower number of switches, was first presented for the possibility of reducing the inverter cost, and it became very attractive as it can be utilized in fault-tolerant control to solve the open/short-circuit fault of the six-switch three-phase (B6) inverter. However, the balance among the phase currents collapses due to the fluctuation of the two dc-link capacitor voltages; therefore, its application is limited. This paper proposes a predictive torque control (PTC) scheme for the B4 inverter-fed induction motor (IM) with the dc-link voltage offset suppression. The voltage vectors of the B4 inverter under the fluctuation of the two dc-link capacitor voltages are derived for precise prediction and control of the torque and stator flux. The three-phase currents are forced to stay balance by directly controlling the stator flux. The voltage offset of the two dc-link capacitors is modeled and controlled in the predictive point of view. In extension system we proposed nine level inverter fed induction motor drive. Compare to existing system proposed system is more efficient system for harmonic reduction as well as smoothing the wave shape.
Optimizing Carbon Storage Operations for Long-Term Safety

To combat global warming and mitigate the risks associated with climate change, carbon capture and storage (CCS) has emerged as a crucial technology. However, safely sequestering CO2 in geological formations for long-term storage presents several challenges. In this study, we address these issues by modeling the decision-making process for carbon storage operations as a partially observable Markov decision process (POMDP). We solve the POMDP using belief state planning to optimize injector and monitoring well locations, with the goal of maximizing stored CO2 while maintaining safety. Empirical results in simulation demonstrate that our approach is effective in ensuring safe long-term carbon storage operations. We showcase the flexibility of our approach by introducing three different monitoring strategies and examining their impact on decision quality. Additionally, we introduce a neural network surrogate model for the POMDP decision-making process to handle the complex dynamics of the multi-phase flow. We also investigate the effects of different fidelity levels of the surrogate model on decision qualities.
Stem rot on Cymbidium ensifolium (Orchidaceae) caused by Fusarium oxysporum in China

Abstract Cymbidium ensifolium is an important cultivated herb in southern China. A severe stem rot disease was observed on C. ensifolium in Fujian Province, China, in April 2016. Initially, the junction of the stem and root turned dark black, and the bottom leaves turned yellow. Subsequently, the leaf base began to rot and the stem turned brown and the entire stem became necrotic. A fungus was isolated from diseased stems with typical symptoms of stem rot. The pathogenicity of the isolated fungus was tested with successful infection of inoculated C. ensifolium plants. Koch’s postulates were confirmed by reisolation of the fungus from the infected tissue on artificially inoculated stems. Based on morphological characteristics and sequence analysis of the internal transcribed spacer and actin genes, the pathogen was identified as Fusarium oxysporum. This is the first report of F. oxysporum causing stem rot in C. ensifolium.
Thoughts on detecting tissue distribution of potential COVID-19 receptors

Aim: As a novel coronavirus, coronavirus disease 2019 (COVID-19) has caused a global epidemic. Many clinical data show that COVID-19 can not only cause viral pneumonia but also damage a variety of target organs. Materials & methods: We searched some open online datasets, such as Gene ORGANizer, the Human Protein Atlas and Pubmed, to explore the tissue distribution of potential COVID-19 receptors (ACE2, CD209, CLEC4M and BSG) in the human body. Results: The above potential COVID-19 receptors were highly expressed in the lungs, intestine, kidney, liver, heart, testis, placenta, hematopoietic tissue and nerve tissue. Conclusion: It is speculated that they may be potentially high-risk organs susceptible to COVID-19 infection. It is expectant to provide some help for further research in the future.
Learning curve for robot-assisted Roux-enY gastric bypass BUCHS

Robot-assisted Roux-en-Y gastric bypass (RYGBP) is rapidly evolving as an important surgical approach in the bariatric field. However, the specific learning curve associated with this new approach remains poorly investigated. This study aimed to evaluate the learning curve for robot-assisted RYGBP. BUCHS, Nicolas, et al. Learning curve for robot-assisted Roux-en-Y gastric bypass. Surgical Endoscopy, 2012, vol. 26, no. 4, p. 1116-21 DOI : 10.1007/s00464-011-2008-3
A Comprehensive Model of Consumers’ Perceptions, Attitudes and Behavioral Intention toward Organic Tea: Evidence from an Emerging Economy

This study investigates factors that predict consumers’ perceptions of healthiness of organic tea. Furthermore, this study also examines the relationship between perceived healthiness and purchase intention with the mediating role of consumers’ attitudes toward organic tea. Because China has been the largest producer and the largest market of the global tea market, this study collects sample data from consumers at different tea stores in China. Using structural equation modelling to analyze data, results indicate that product quality, consumer service, in-store experience, store prestige, and store innovativeness are important predictors of consumers’ perceptions of healthiness of organic tea. Furthermore, results show that perceived healthiness has a positive influence on purchase intention toward organic tea. Consumers’ attitudes toward organic tea also has a positive mediating effect into this relationship.
A Stu2-mediated intrinsic tension-sensing pathway promotes chromosome biorientation in vivo

Accurate segregation of chromosomes to daughter cells is a critical aspect of cell division. It requires the kinetochores on duplicated chromosomes to biorient, attaching to microtubules from opposite poles of the cell. Bioriented attachments come under tension, while incorrect attachments lack tension and must be destabilized. A well-studied error correction pathway is mediated by the Aurora B kinase, which destabilizes low tension-bearing attachments. We recently discovered that in vitro, kinetochores display an additional intrinsic tension-sensing pathway that utilizes Stu2. This pathway’s contribution to error correction in cells, however, was unknown. Here, we identify a Stu2 mutant that abolishes its kinetochore function and show that it causes error correction defects in vivo. We also show that this intrinsic tension-sensing pathway functions in concert with the Aurora B-mediated pathway. Together, our work indicates that cells employ at least two pathways to ensure biorientation and the accuracy of chromosome segregation.
