Prejudice in disguise: Which features determine the subtlety of ethnically prejudicial statements?

In current immigration debates ethnic prejudice is often expressed in a subtle manner, which conceals its xenophobic content. However, previous research has only insufficiently examined the specific features that make certain ethnically prejudicial statements subtler, i.e., less readily identifiable as xenophobic, than others. The current study employs an experimental factorial survey design and assesses the subtlety of systematically manipulated prejudicial statements. Our data from a German random population sample (N = 895) indicate that the subtlety of ethnically prejudicial statements is manipulable along the dimensions of topic, linguistic (essentialist) phrasing, and target group: Prejudicial statements that refer to culture, that are phrased weakly essentialistically, and that target Muslims were subtlest, in being evaluated as least xenophobic by the respondents. Moreover, with an increasing internal and a decreasing external motivation to respond without prejudice, individuals reacted more strongly to the variation of the statements’ topic and linguistic phrasing and were thus more sensitive to features determining subtler and more blatant ways of ethnic prejudice expression. These findings contribute to a better understanding of current migration discourses, in demonstrating that the specific manner in which ethnic prejudice is communicated can camouflage the xenophobic nature of a statement, so that it is less readily recognized as prejudicial.
Feasibility and Economic Impacts of the Energy Transition

There is currently no consensus regarding whether or not renewable energies are capable of supplying all of our energy needs in the near future. To shed new light on this controversy, this paper develops a methodology articulating a macroeconomic model with two sectors (energy and non-energy) and an energy model that is able to calculate the maximum potentials of solar and wind energy. The results show that, in a business-as-usual context, a complete energy transition on a global scale is unachievable before the end of the century. The reason lies in the increasing capital needs of the energy sector, which slows, if not stops, economic growth and the energy transition. A complete transition can be achieved by 2070 provided that (i) energy demand is kept under control at its current level, (ii) a sufficient rate of capital growth is sustained (above its historical level), and (iii) substantial progress is made in terms of energy efficiency. However, this strategy requires a significant increase in the savings rate, with a negative impact on consumption, which ends up stagnating at the end of the transition.
Identification and expression analysis of E2 ubiquitin-conjugating enzymes in cucumber

Abstract: Protein ubiquitination is one of the most common modifications that can degrade or modify proteins in eukaryotic cells. The E2 ubiquitin-conjugating enzymes (UBCs) are involved in multiple biological processes of eukaryotes and their response to adverse stresses. Genome-wide survey of the UBC gene family has been performed in many plant species but not in cucumber (Cucumis sativus). In this study, a total of 38 UBC family genes (designated as CsUBC1–CsUBC38) were identified in cucumber. The phylogenetic analysis of UBC proteins from cucumber, Arabidopsis and maize indicated that these proteins could be divided into 15 groups. Most of the phylogenetically related CsUBC members had similar conserved motif patterns and gene structures. The CsUBC genes were unevenly distributed on seven chromosomes, and gene duplication analysis indicated that segmental duplication has played a significant role in the expansion of the cucumber UBC gene family. Promoter analysis of these genes resulted in the identification of many hormone-, stress- and development-related cis-elements. The CsUBC genes exhibited differential expression patterns in different tissues and developmental stages of fruit ripening. In addition, a total of 14 CsUBC genes were differentially expressed upon downy mildew (DM) infection compared with the control. Our results lay the foundation for further clarification of the roles of the CsUBC genes in the future.
Genetic Differentiation of Clariid Populations using Microsatellite Markers in Kano State Rivers

This study aimed to investigate the genetic characterization of strains of Clariid fish species in some river bodies in Kano State using microsatellite markers.One hundred and seventy seven Clariid fish samples (Clariasgariepinus and Heterobranchuslongifilis) were collected from six rivers (Thomas, Ghari, Tiga dam, Duddurun Gaya, Karaye and Bagwai) in Kano state. Blood sample was taken from each fish sample by severing the caudal peduncle and drained into FTA cards for DNA extraction, Polymerase Chain Reaction and electrophoresis to determine genetic variation between the Clariid fish populations.Genealex 6.4 software package was used to analyse the resolve bands from DNA extraction to determine their base pair and genetic variation. Results showed that the Fst values ranged from 0.00 to 0.66, Fit ranged from -0.04 to 0.12, Fis ranged from -0.35 to -0.26. It indicated a Original Research Article Suleiman et al.; AJBGMB, 7(4): 35-45, 2021; Article no.AJBGMB. 66601 36 large number of gene flow (exchange) among the populations with a range of 0.46 to 0.87. There was an established magnitude of genetic divergence (91.86%) among the populations as shown by the result of the percentage polymorphism which depends on the number of alleles detected per locus and their frequencies. It can be concluded that since there was no inbreeding as shown in the study, none of the population exhibited genetic uniqueness. The populations had a high genetic differentiation between populations but moderate differentiation within populations. The populations were outbred populations; an indication that relatives avoided mating in the population.
Shear deformation theory for free vibration responses of 3D braided pre-twisted conical shells under rotation

Abstract 3D braided composite has significant attractiveness compared to the classical composite, such as better in-plane mechanical properties, strength in the thickness directions, damage tolerance, anti-delamination capability, etc. In the present work, a new shear deformation theory with 12 degrees of freedom per node is implemented in the framework of the 3D finite element formulation for the free vibration analysis of 3D braided pre-twisted conical shells under rotation. For moderate rotational speeds, the Coriolis effect is neglected. The equivalent material properties of the 3D braided rotating conical shells are computed by bridging models base on a volume averaging method (VAM).
Antecedents and Implications of Innovation Capability: Empirical Study of Bakpia MSMEs in Yogyakarta

Introduction/Main Objectives: This research examines the antecedents and implications of innovation capability, empirically. The outcomes aim at contributing to the knowledge and understanding about the main driver of innovation capability. Background Problems: Yogyakarta is known for its many and varied charms, its tourist attractions, the availability of facilities and infrastructure to support tourism, such as souvenir sellers. But there is known that number of total foreign and domestic tourists has been a decrease in 2018 (Semester I by 11.51% and II by 3.33%), also in 2019 (Semester I by 11.23%). This is a challenge for MSMEs in the tourism sector and MSMEs in other sectors that support tourism, such a souvenir seller. Bakpia is one of the well-known products of the food and beverage sector in Yogyakarta often bought for souvenirs. The Bakpia MSMEs’ innovations were triggered by competition among the Bakpia producers in Yogyakarta. Therefore, every Bakpia MSME must be competitive to survive in the market. Thus, there is a need to improve their innovation capability, which will impact the innovation performance of the Bakpia MSMEs in Yogyakarta. There is a gap in the research regarding the influence of the factors that are predicted to build innovation capability. Novelty: Previous studies’ results indicate that the influence of knowledge donating and knowledge collecting about innovation performance is not yet conclusive. Therefore, this study aims to fill the gap in the previous research by examining the role of capability as a mediating between knowledge sharing process (knowledge donating and knowledge collecting) to innovation performance. Research Methods: Forty-eight items of data were obtained from Bakpia MSMEs in Yogyakarta through a survey conducted by distributing questionnaires directly to them. The data were analyzed using PLS-SEM via SmartPLS version 3.3. 2. Findings/Results: This study shows that the direct and indirect effects of sharing knowledge (which includes donating and collecting knowledge) about innovation performance are found to be positive but not significant. The results also indicate that innovation capability does not significantly mediate knowledge donating and knowledge collecting about innovation performance. Meanwhile, the influence of innovation capability on innovation performance was found to be positive and significant. Conclusion: The antecedents are insignificant for innovation capability, but the antecedent’s constructs still act as a driver to build innovation capability.
Synthesis and Simple Immobilization of Palladium(II) Acyclic Diaminocarbene Complexes on Polystyrene Support as Efficient Catalysts for Sonogashira and Suzuki–Miyaura Cross-Coupling

Immobilization of palladium(II) acyclic diaminocarbene (Pd(II)-ADC) complexes on a resin support surface has been easily performed by metal-mediated addition of amino groups of benzhydrylamine-polystyrene to the coordinated isocyanide ligand of cis-PdCl2(CNR)2 (R = t-Bu, Cy). The investigation of the benzhydrylamine reaction with palladium-coordinated isocyanides in solution has revealed that, depending on the reaction conditions, two carbene-type complexes can be obtained as a result of the addition to the CN triple bond, as well as a third complex which is formed via substitution of the isocyanide ligand by benzhydrylamine. Nucleophilic addition of an amino group to the isocyanide ligand has led to a cis-acyclic diaminocarbene complex or a cationic diaminocarbene complex with trans configuration and an intramolecular hydrogen-bonded chloride anion (the nature of this noncovalent interaction was analyzed by DFT calculations, including AIM analysis). The unsupported and resin-supported palladium catalysts.
Teacher job satisfaction in Taiwan: making the connections with teacher attitudes, teacher self-efficacy and student achievement

PurposeThis paper aims to describe the findings of a study investigating the relationships between teacher attitudes to teaching mathematics, teacher self-efficacy, student achievement and teacher job satisfaction in Taiwan.Design/methodology/approachData were collected from 110 fifth grade primary school teachers and their students (n = 2,334) between 10 and 10 years old. A teacher questionnaire and a criterion-reference test in mathematics were distributed during the academic year 2016–2017. The data were analysed using confirmatory factor analysis and stepwise linear regression.FindingsThe results revealed that teacher attitudes to teaching mathematics, efficacy in classroom environment and student achievement in mathematics could, to some extent, explain variations in teacher job satisfaction. Of all the variables, teacher attitudes to teaching mathematics explained the largest portion of the variance in teacher job satisfaction.Originality/valueThese findings support the proposition that teacher attitudes to teaching mathematics affect teacher job satisfaction, which is in turn, translatable into enhanced teacher effectiveness. It is important to note that this study explores the impact of student achievement on teacher job satisfaction (and not the other way round), which is a relationship that remains under-researched and needs further investigation. Implications of the findings are discussed, and suggestions for further studies are provided.
Opening the “Black Box” of University Entrepreneurial Intention in the Era of the COVID-19 Pandemic

This research aims to study the determinants of entrepreneurial intention in academia and compare the outcomes from two different moments, before and during the COVID-19 pandemic. For this purpose, a quantitative methodology was used, whereby a questionnaire was given to higher education students in these two chronological moments. From the obtained results, it was possible to ascertain that, given the motivational dimension, the attitude towards behavior and perceived behavioral control are having a positive impact on entrepreneurial intentions during the pandemic and that subjective norms have a negative impact on entrepreneurial intentions. This relationship of influences is unchanged, either before or during the pandemic. Regarding the environmental dimension, both of the variables under analysis are having a negative impact on entrepreneurial intention during the pandemic period, which corresponds to an aggravation or loss of positive influences when compared to the context before the pandemic, and the next assessment had a positive impact on entrepreneurial intentions. On the theoretical contributions, the findings are very important, as they strengthen the literature on entrepreneurial intentions, and in specific contexts of social and economic instability. As for practical contributions, this research suggests actions to agents with an important intervention role in the community, one of these agents is Higher Education Institutions, which play a determining role by creating a positive environment to support their students’ entrepreneurial intent. This research is original, as far as we are informed, and it is the first to study entrepreneurial intention in academia during the COVID-19 pandemic in the Portuguese context. Moreover, we suggest that the obtained results should be succeeded by further studies to confirm the evolutionary trends now identified on the subject under analysis.
Comparative Study of the Nutrient Composition of Four Varieties of Cowpea (Vigna unguiculata) and Their Products (Beans-Based Products)

The study compared the nutrient potentials of four varieties of cowpea (Vigna unguiculata) and their products (beans pottage). The four cowpea varieties were obtained from the main market Nsukka, Enugu state. The varieties were: Potiskum (black-eye pea), Ife-brown (brown beans), Orarudi and Aloka. Five hundred gram of each sample was cleaned by hand picking to remove extraneous materials and damaged seeds. The cowpea grains were divided into two portions of 100 and 400 g, respectively. Four hundred gram of each of the varieties was used to prepare beans pottage. The sensory properties of the pottage were evaluated using a nine-point hedonic scale while the Food Attitude Rating Scale was used to access the general acceptability. The raw samples and the pottage were analyzed chemically for nutrient and anti-nutrient composition. The data generated was statistically analyzed using means, Analysis of Variance and Duncans New Multiple Range Test (DNMRT). In the raw samples Ife-brown was found to have the highest protein content (26.90%) while in the cooked sample Potiskum pottage was found to have the highest protein content (15.70%). However, Ife-brown and Aloka rated the highest in nutritive value in terms of proximate (moisture, protein, fats, carbohydrate, fibre and ash) and minerals (calcium, zinc, phosphorus, potassium and iron). The pottage had comparable (p>0.05) acceptability. However, Ife-brown bean pottage was best preferred to the other pottage.
Enhanced Sensitivity of Nonsmall Cell Lung Cancer with Acquired Resistance to Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitors to Phenformin: The Roles of a Metabolic Shift to Oxidative Phosphorylation and Redox Balance

Background Although the efficacy of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR- TKI) therapy has been proven in non-small cell lung cancer (NSCLC) patients, acquired resistance to EGFR-TKIs presents a serious clinical problem. Hence, the identification of new therapeutic strategy is needed to treat EGFR-TKI-resistant NSCLC. Methods Acquired EGFR-TKI-resistant lung cancer cell lines (HCC827, H1993, and H292 cells with acquired resistance to gefitinib or erlotinib) were used for cell-based studies. IncuCyte live cell analysis system and XFp analyzer were used for the determination of cell proliferation and energy metabolism, respectively. In vivo anticancer effect of phenformin was assessed in xenografts implanting HCC827 and gefitinib-resistant HCC827 (HCC827 GR) cells. Results HCC827 GR and erlotinib-resistant H1993 (H1993 ER) cells exhibited different metabolic properties compared with their respective parental cells, HCC827, and H1993. In EGFR-TKI-resistant NSCLC cells, glycolysis markers including the glucose consumption rate, intracellular lactate level, and extracellular acidification rate were decreased; however, mitochondrial oxidative phosphorylation (OXPHOS) markers including mitochondria-driven ATP production, mitochondrial membrane potential, and maximal OXPHOS capacity were increased. Cell proliferation and tumor growth were strongly inhibited by biguanide phenformin via targeting of mitochondrial OXPHOS complex 1 in EGFR-TKI-resistant NSCLC cells. Inhibition of OXPHOS resulted in a reduced NAD+/NADH ratio and intracellular aspartate levels. Recovery of glycolysis by hexokinase 2 overexpression in erlotinib-resistant H292 (H292 ER) cells significantly reduced the anticancer effects of phenformin. Conclusion Long-term treatment with EGFR-TKIs causes reactivation of mitochondrial metabolism, resulting in vulnerability to OXPHOS inhibitor such as phenformin. We propose a new therapeutic option for NSCLC with acquired EGFR-TKI resistance that focuses on cancer metabolism.
Coeliacs cannot live by gluten-free bread alone – every once in awhile they need antioxidants

Summary This comprehensive review, covering scientific papers published from 2013 until now, deals with the bioactivity of available gluten-free matrices. For this purpose, cereals (rice, maize, sorghum, teff and millets), pseudocereals (buckwheat, quinoa and amaranth) and noncereals (pulses as lentils, fruits as bananas, vegetables as potatoes and nuts as chestnuts, among others) sources are studied. The current trends in enhancing the antioxidant activity of gluten-free baked products by incorporating natural bioactive compounds are presented. This review covers a wide range of natural bioactive sources such as starchy materials or its by-products; spices, herbs or green plant materials and vegetable and seeds or fruits. Special emphasis was put on describing the changes in antioxidant activity that can occur, between raw matrices and enriched final products, during baking process. Possible future trends in the improvement of antioxidant properties of gluten-free baked products, based on bioactive sources which have already been applied in the gluten bread industry, were also discussed.
More than race: a comparative analysis of “new” Indian and Chinese migration in Singapore

ABSTRACT Singapore is a nation-state characterized by the convergence of multiple diaspora populations. The state and citizens alike cannot ignore a sharpened sense of difference that has led to social tensions between “old” and “new” waves of migrants/immigrants, in particular amongst those considered co-ethnics from India and China. Comparative analyses of Indian and Chinese migration are few, resulting in a narrow understanding of how both impact migrant-receiving societies simultaneously. Our paper identifies commonalities undergirding the racialization experienced by co-ethnic migrants/immigrants in Singapore. We argue that multiple dimensions of personhood – to do with one’s skills, class and legal statuses; performances of “authenticity” and temporal framings of migration; and wider civilisational and developmental discourses – work together to create “polysemic immigration hierarchies”. Singapore’s experience illuminates subtle forms of inter- and co-ethnic racialization – drawing on, yet exceeding, tropes of “colour”.
Effect of Water Extract of Urtica dioica L. on Lipid Oxidation and Color of Cooked Pork Sausage

The aim of this study was to determine the effectiveness of water extract and dried leaves of Urtica dioica in reducing lipid oxidation and color stabilization of cooked sausage. Four variants of sausages were prepared: control (without nettle); sausages with 300 ppm and 600 ppm water extract of nettle; and sausages with dried nettle leaves. TBARS values, color parameters, ORP, pH, aw and sensory attributes of sausages were investigated. The addition of nettle (water extract/dried leaves) did not affect the pH, aw and ORP of the sausages. The addition of nettle water extract (600 ppm) decreased the TBARS value and increased the color stability of sausages during storage. The sensory quality of the samples with added water extract of nettle was greater than that of the remaining samples. This study suggests that water extract of nettle can be used in cooking sausage to reduce lipid oxidation and to increase the stability of color. Practical Applications Oxidation is a problem encountered in the food industry. The minced meat products are particularly vulnerable to changes in oxidation. Lipids oxidation and oxidation of heme pigments are the main reactions occurring in the meat products during storage and have an effect on their health. The use of natural antioxidants has increased because of the high demand for healthful food products. Many spices and herbs show antioxidant activity. This article deals with the use of Urtica dioica water extract and dried leaves as a functional ingredient in cooked pork sausages.
Response of Tannat (Vitis vinifera L.) to pre-flowering leaf removal in a humid climate

The aim of this study was to test the effect of pre-flowering leaf removal (PFD) on grape sanitary status, yield, source-sink balance and berry composition. A completely random block design experiment was conducted over four seasons in a commercial vineyard of the Tannat/SO4 combination located in the south of Uruguay (34° 35´30 S, 56° 15´23 O). The PFD treatment was compared with a commercial defoliation (CC) comprising partial leaf removal between the fruit set and cluster closure stages (four leaves from the first node), a traditional practice carried out by winegrowers. Both treatments received equal phytosanitary management during the study. The results were conditioned by seasonal meteorological conditions, particularly rainfall, temperature and evapotranspiration. The seasonal effect was significant for yield components, berry composition and source-sink balance. The PFD treatment resulted in the lowest yields in all four years and modified the primary and secondary composition of berries. It also showed a higher anthocyanin potential in 2016, 2017 and 2019, related to a higher percentage of exposed clusters, lower yield and/or higher leaf to fruit ratio. In 2017, environmental conditions were more favourable for the development of bunch rot, and lower values of incidence (3 %) were recorded for the PFD treatment compared to CC (22 %), due to greater exposure of bunches and less compact bunches. The PFD vines showed a steady reduction in dry matter production capacity, mainly explained by the steady reduction in yields. The Tannat variety showed a differential response to PFD depending on the weather during the growth cycle. Under humid climate conditions, pre-flowering defoliation proved to be effective for yield control, by reducing bunch rot incidence, and for improving some attributes in terms of grape composition. This work provides useful information for grape growers in humid regions on how to improve the sanitary status and quality of their production.
