    At the beginning of the 21st century the task of re-examining the role of the state in economic development is becoming increasingly important for African policymakers because most countries have undergone some form of either externally imposed or self-imposed Structural Adjustment. The Structural Adjustment Programmes (SAPs) have, however, had different outcomes in the different countries but none has succeeded in alleviating poverty and stimulating sustained development. In general however, SAPs have discouraged the state from playing a developmental role, because of a misconception that government should not have any role in the economy other than the regulation of economic activities and the enforcement of law and order. Therefore, in the light of the widespread poverty, and the high levels of unemployment and income inequality in most African countries, it is clear that the state must have a significant role in economic development.

    This study aims to investigate the direct and indirect effect of brand experience on consumer brand relationship, brand preference and customer satisfaction through self-concept. Non probability sampling technique was applied. The primary data were collected from 297 (n = 297) Pakistani customers. The proposed theoretical model was tested using structural equation modeling in PLS Smart. Results showed that brand experience has strongest direct effect on consumer brand relationship, followed by brand preference, and then customer satisfaction. The results of indirect effect revealed that the self-concept emerged as a stronger driver for brand experience and consumer brand relationship, then for brand preference and customer satisfaction. Additionally, the implications for academicians and practitioners are discussed. Keywords: Brand experience, consumer brand relationship, brand preference, customer satisfaction, self-concept

    AbstractHere, we report a high-quality draft genome of a Chinese radish (Raphanus sativus) cultivar. This draft contains 387.73Mb of assembled scaffolds, 83.93% of the scaffolds were anchored onto nine pseudochromosomes and 95.09% of 43 240 protein-coding genes were functionally annotated. 184.75Mb (47.65%) of repeat sequences was identified in the assembled genome. By comparative analyses of the radish genome against 10 other plant genomes, 2 275 genes in 780 gene families were found unique to R. sativus. This genome is a good reference for genomic study and of great value for genetic improvement of radish

    PgtE Enzyme of Salmonella enterica Shares the Similar Biological Roles to Plasminogen Activator (Pla) in Interacting With DEC-205 (CD205), and Enhancing Host Dissemination and Infectivity by Yersinia pestis

    Yersinia pestis, the cause of plague, is a newly evolved Gram-negative bacterium. Through the acquisition of the plasminogen activator (Pla), Y. pestis gained the means to rapidly disseminate throughout its mammalian hosts. It was suggested that Y. pestis utilizes Pla to interact with the DEC-205 (CD205) receptor on antigen-presenting cells (APCs) to initiate host dissemination and infection. However, the evolutionary origin of Pla has not been fully elucidated. The PgtE enzyme of Salmonella enterica, involved in host dissemination, shows sequence similarity with the Y. pestis Pla. In this study, we demonstrated that both Escherichia coli K-12 and Y. pestis bacteria expressing the PgtE-protein were able to interact with primary alveolar macrophages and DEC-205-transfected CHO cells. The interaction between PgtE-expressing bacteria and DEC-205-expressing transfectants could be inhibited by the application of an anti-DEC-205 antibody. Moreover, PgtE-expressing Y. pestis partially re-gained the ability to promote host dissemination and infection. In conclusion, the DEC-205-PgtE interaction plays a role in promoting the dissemination and infection of Y. pestis, suggesting that Pla and the PgtE of S. enterica might share a common evolutionary origin.Peer reviewe

    The association between changes in public sentiment induced by COVID-19 and green consumption behavior has not been studied deeply. This study proposes that the awe induced by the COVID-19 pandemic can have both negative and positive aspects, aiming to psychologically reveal why the pandemic is affecting green consumer behavior and explore potential pathways for differentiation. Research data were derived from Wuhan, China, and analyzed using experimental method. This study finds that awe of COVID-19 positively affects green consumption behavior. Specifically, due to fear, anxiety, and powerlessness, individuals with negative awe of COVID-19 instinctively need to respond to risk and pay more attention to their own safety and interests, so as to promote green consumption. However, positive awe of COVID-19 involves higher levels of cognition, such as admiration, inspiration, and optimism. It inspires a commitment to prioritize nature and social groups, and promotes green consumption behavior. As conclusions, different types of awe can be induced from public health emergencies like COVID-19 and have their own specific paths to effect green consumption behavior. These findings could help governments and marketers build future policies and strategies to reasonably guide public sentiment in order to better promote green consumption in this epidemic

    Green brand evangelism builds an important psychological and behavioral basis on promoting the positive interaction between green brands and consumers, as well as on realizing the co-creation of green brand value. This study selects brand authenticity issues as the entry point and investigates brand authenticity on green brand evangelism. In particular, this study tests the effects of green transparency and green skepticism on brand authenticity, as well as the role of self-brand connection and the need for cognition on the relationship between brand authenticity and green brand evangelism. With a sample of 641 Chinese respondents of green building materials, the dimension and scale of green brand evangelism were acquired by utilizing the grounded theory, and the hypothesized relationships were tested by employing structural equation modeling. The findings suggest that green transparency and green skepticism yield an influence on brand authenticity, and brand authenticity exerts a great influence on green brand authenticity. Moreover, brand authenticity positively affects self-brand connection, which in turn positively influences green brand authenticity, and the relationship between brand authenticity and green brand evangelism is regulated by the need for cognition

    Tetrahymena pyriformis, a freshwater protozoan, is common in aquatic systems. Arsenic detoxification through biotransformation by T. pyriformis is important but poorly understood. Arsenic metabolic pathways (including cellular accumulation, effluxion, biomethylation, and volatilization) of T. pyriformis were investigated at various phosphate concentrations. The total intracellular As concentration increased markedly as the external phosphate concentration decreased. The highest concentration was 168.8 mg·kg−1 dry weight, after exposure to As(V) for 20 h. Inorganic As was dominant at low phosphate concentrations (3, 6, and 15 mg·L−1), but the concentration was much lower at 30 mg·L−1 phosphate, and As(V) contributed only ~7% of total cellular As. Methylated As contributed 84% of total As at 30 mg·L−1 phosphate, and dimethylarsenate (DMAs(V)) was dominant, contributing up to 48% of total As. Cellular As effluxion was detected, including inorganic As(III), methylarsenate (MAs(V)) and DMAs(V). Volatile As was determined at various phosphate concentrations in the medium. All methylated As concentrations (intracellular, extracellular, and volatilized) had significant linear positive relationships with the initial phosphate concentration. To the best of our knowledge, this is the first study of As biotransformation by protozoa at different phosphate concentrations
