Substrates and Temperatures in the Germination of Hibiscus sabdariffa L. Seeds

Vegetable biodiversity in Brazil accounts for almost 67% of the plants on the planet, which are part of studies with focus on determinants of food security and access to adequate and healthy food, while preserving natural resources. Studies indicate that Hibiscus sabdariffa L. is one of the most studied unconventional food crops because of its nutraceutical quality as antioxidant and prevention of hypertension and cancer. Although relevant, substrate and temperature information for seedling production of this species are scarce. Thus, the aim of this study was to evaluate the best substrate and temperature for the vigor and germination test of H. sabdariffa seeds of the Talo Roxo and Rubra varieties. The experiment was laid out in a randomized complete design, in a 7 × 5 factorial arrangement, consisting of the combinations of seven substrates (paper towel, filter paper, vermiculite, between sand, on sand, plantmax® and compost) with five temperatures (20, 25, 30, 35 and 20-30 °C), with four replicates with 50 seeds each. The following variables were evaluated: germination, germination speed index, seedling length and dry mass. For germination and vigor tests of Hibiscus sabdariffa var. Talo Roxo seeds the paper roll substrate is recommended at temperatures of 25 or 35 °C and for var. Rubra seeds, plantmax® at 25 °C and plantmax® and vermiculite at temperatures of 25 or 20-30 °C, respectively.

Global mindset and the performance of Chinese firms

More and more Chinese firms are pursuing internationalization strategies. However, most of them have not managed to succeed in the global markets. One possible reason for such failure is their lack of a proper global mindset. This study investigates the following three issues: first, how global minded Chinese firms are; second, what the critical drivers for their global mindedness are; third, what strategic orientation these Chinese firms adopt when they pursue internationalization strategies and how their global mindedness is related to their performance. Results indicate that first, the current level of global mindedness of most Chinese firms are fairly low. Second, experience with foreign culture, leadership vision and firm capacity are important determinants of a firm’s global mindedness. Third, global minded Chinese firms tend to pursue aggressive and risky internationalization strategies and they generally perform better than those with low level of global mindedness.
Turbulence modelling for separated flows with anisotropy-resolving closures

This paper discusses aspects of modelling turbulent flows, featuring curvature, impingement and separation, with statistical second–moment closure and nonlinear eddy–viscosity models. Both modelling approaches are first reviewed, with particular emphasis placed on the illumination of some of the mechanisms by which the alternative model forms capture the interactions between particular types of strain and the turbulence field. As part of the review, recent modelling developments, directed especially towards the prediction of physically complex flows, are presented and discussed. Finally, the predictive performance of selected models is illustrated by way of computational solutions and related comparisons with experimental data for five flows, three two dimensional and two three dimensional, all involving separation from continuous surfaces.
Assessing procrastination in Korean: A study of the translation and validation of the Pure Procrastination Scale and a reexamination of the Irrational Procrastination Scale in a student and community sample

Abstract Procrastination refers to voluntarily delay an intended course of action despite expecting that it might have negative consequences. It is usually assessed by self-reports, and the two most frequently used scales are the Pure Procrastination Scale (PPS) and the Irrational Procrastination Scale (IPS). The current study sought to investigate the reliability and validity of the two scales in Korean by translating the PPS from English and to reexamine a previous translation of the IPS. The aim is to promote further research on procrastination and to enhance a cross-cultural comprehension of the construct in different contexts. Hence, confirmatory factor analyses were conducted using data from 551 participants in a student and community sample. Convergent and discriminant validity, internal consistency, and test-retest reliability were also assessed. A three-factor solution exhibited an adequate fit for the PPS; decisional procrastination, implemental procrastination, and timeliness and promptness, although a one-factor solution with only the implemental part performed equally well. Meanwhile, a one-factor solution exhibited a reasonable fit for the IPS. Both scales correlated moderately with anxiety, r = . 36-. 37, depression, r = . 37-. 38, self-efficacy, r = . -34 to −. 38, and quality of life, r = −. 32 to −. 34, all in the expected directions, but not so for perfectionism, r =. 09-. 10. Internal consistencies, Cronbach’s α = . 93 (the PPS) and.85 (the IPS), and test-retest reliabilities (two weeks), r = . 88 (the PPS) and.83 (the IPS), were good. The findings indicate that the Korean versions might be reliable and valid for researching procrastination.
An evolutionary-conserved redox regulatory mechanism in human Ser/Thr protein kinases

Reactive oxygen species (ROS) are products of oxygen metabolism, but are also recognized as endogenous physiological mediators of cellular signaling. Eukaryotic protein kinase (ePK) regulation occurs through reversible phosphorylation events in the flexible activation segment. In this study, we demonstrate that the catalytic phosphotransferase output from the mitotic Ser/Thr kinase Aurora A is also controlled by cysteine (Cys) oxidation. Reversible regulation occurs by direct modification of a conserved residue (Cys 290), which lies adjacent to Thr 288, the activating site of phosphorylation. Strikingly, redox modulation of the Cys 290-equivalent in other ePKs is predicted to be an underappreciated regulatory mechanism, since ~100 human Ser/Thr kinases possess a Cys at this position in the conserved activation loop. Using real-time enzyme assays, we confirm that the presence of the equivalent Cys residue is prognostic for redox-sensitivity amongst a cohort of human CAMK, AGC and AGC-like kinases, including AKT, AMPK, CAMK1, MAPKAP-K2/3 and SIK1-3. Our findings demonstrate that dominant Cys-based redox-switching in the activation segment represents an evolutionary-conserved mode of regulation for a significant subset of the human kinome. This finding has important implications for understanding physiological and pathological signaling responses to ROS, and emphasises the importance of multivalent activation segment regulation in ePKs. ONE-SENTENCE SUMMARY The catalytic activity of Ser/Thr kinases is regulated through a conserved Cys-based redox mechanism.
Attitudes Toward Mobile App Payment Systems: A Case Study Among Indonesian Millennials

This study adapted the Technology Acceptance Model (TAM) to examine the usefulness of mobile apps, value-for-money, emotional value, and individual mobility factors that influence Indonesian millennials’ attitudes toward mobile app payment systems and how their attitudes mediate these four variables on continuance intention. Partial Least Square (PLS) was used to analyze the data collected from 310 Indonesian millennials. Individual mobility was a strong factor influencing millennial attitudes toward mobile app payment services, followed by usefulness of the apps and value-for-money. Emotional value did not influence millennial attitudes toward the payment apps. The current research provides useful insights into millennials’ attitudes toward mobile app payment services. Managers and decision-makers can take into account the following insights in order to enhance millennials’ positive attitudes and continuance intention toward mobile app payment services.
Emergency service units in Turkey dont have enough resources to implement the one- hour sepsis bundle components and sepsis guidelines recommendations, 238 emergency department directors opinion

Aim: Aim of this study is to investigate whether emergency rooms in Turkey have sufficient resources to treat sepsis patients. Sepsis has a high incidence and can result in multiple organ failure and death within hours if not rapidly intervened. Septic patients, are generally first admitted to the emergency departments. In the management of these patients, it is very important to have well -knowledged team and enough resources. Materials and Methods: A questionnaire regarding whether education and emergency room resources were sufficient to diagnose and treat sepsis was e-mailed to the directors of emergency department. Data collection took place from December 17, 2019 to December 27, 2019. Results: The study included 238 participants, of who worked in university hospitals, training and research hospitals, state hospitals, and inprivate hospitals. The first health care professional to examine emergency patients was a physician in 162 of the hospitals, and a nurse in 76. Sepsis treatment was delayed due to laboratory test delays in 77 hospitals, triage patient non-determinability in 62, and diagnosis delays in 33. Staffing was inadequate, with 54 participants reporting difficulties in reaching an emergency medicine physician, 124 in reaching an infectious disease physician, 203 in reaching a microbiologist, and 125 in reaching an intensive care physician. Conclusion: Emergency rooms in Turkey suffer from limited resources to properly implement sepsis treatment guidelines and bundles. Resources should be improved .
Enhancing Electromagnetic Backscattering Responses for Target Detection in the Near Zone of Near-Field-Focused Phased Array Antennas

The analysis of electromagnetic (EM) scattering from a target located in the near zone of an electrically large near-field-focused (NFF) array of antennas is presented. The analysis first examined the EM scattering from a metal sphere, attempting to create a reference for comparison with other targets in a fashion analogous to conventional far-field analysis of radar cross section (RCS). Realistic targets were afterward examined and analyzed to exhibit their RCS characteristics. A numerical simulation-based maximization of EM scattering fields for effective target detection in the near zone of antenna was developed, which allows one to obtain a set of optimum element excitation weightings by applying the steepest ascent method (SAM). RCS phenomena were validated by full-wave simulations and experimental measurements to justify the feasibility of the proposed concept.
Tandem Directional CTCF Sites Balance Protocadherin Promoter Usage

CTCF is a key insulator-binding protein and mammalian genomes contain numerous CTCF-binding sites (CBSs), many of which are organized in tandem arrays. Here we provide direct evidence that CBSs, if located between enhancers and promoters in the Pcdhα and β-globin clusters, function as an enhancer-blocking insulator by forming distinct directional chromatin loops, regardless whether enhancers contain CBS or not. Moreover, computational simulation and experimental capture revealed balanced promoter usage in cell populations and stochastic monoallelic expression in single cells by large arrays of tandem variable CBSs. Finally, gene expression levels are negatively correlated with CBS insulators located between enhancers and promoters on a genome-wide scale. Thus, single CBS insulators ensure proper enhancer insulation and promoter activation while tandem-arrayed CBS insulators determine balanced promoter usage. This finding has interesting implications on the role of topological insulators in 3D genome folding and developmental gene regulation.
Top management teams and investment decisions: A study of executive experience and cultural diversity

Hambrick and Mason (1984) introduced the upper echelons theory (UET) to assist in understanding how top management teams (TMT) make decisions. UET provides that organizational outcomes are a reflection of the values and cognitive biases of senior management in the organization. The theory further states that the TMT perception of their corporate environment influences the strategic choices they make. In the last five decades, multinational corporations (MNCs) have had to adapt to globalization and the increasing complexity that follows (Hitt, Li, & Xu, 2016; Tian & Slocum, 2015). This increasingly global landscape leads to ensuing pressures on top management to internationalize their firms, which puts an emphasis on selecting and retaining decision-makers with international experience (Nielsen & Nielsen, 2011). However, within the literature, there has been a void in the exploration of the relationships between executive Abstract
A Felt Truth: Value Congruence in Family Firms

Family firms are known for having a strong culture and shared values, which arise from the ways in which family traditions and dynamics influence the business. Value congruence is known for having positive effects on employees’ affective commitment, which is strongly connected to organisational performance. Thus, one can assume that a strong family influence on a business entails strong congruency between employees’ and firms’ values. To explore this topic in more depth, the present paper employs theoretical strands from family business research and person-organisation-fit theory. To examine the relationship between family influence, value congruence and their effect on affective commitment, this study conducted an online survey among 15 family firms that were categorized according to their family influence. The paper compared firms with weak and strong family influence in terms of employees’ value congruence and their affective commitment, as well as considered potential influencing factors such as leadership, management stewardship, and tenure. Different methods were used to analyse the data. The findings indicate that family firms with a strong family influence have higher levels of perceived value congruence and affective commitment among employees.
Breeding Practices, Reproductive and Productive Performance of Dairy Cows: The Case of West Wollega Zone, Gimbi District, Ethiopia

The study was conducted from January 2018 to May 2018 with the objective of studying breeding practices, reproductive and productive performance of dairy cows in Gimbi district, west Wollega zone. A total of 120 dairy producers were randomly selected from four representative kebeles (Chuta Giyorgisi, Lelisa Yesus, Bikiltu Tokuma and Enango Dembali) and interviewed. A semi-structured questionnaire was employed to gather the required data and the collected data were analyzed by using statistical package for social science (SPSS Version 20). As the study result indicated about 89% of the households were used natural mating as method of breeding and only 3% of them were utilized AI but they perceived as it had no worth. The mean age at first service (AFS), age at first calving (AFC) and calving interval (CI) of local cows was 42.23 ± 7.4; 51.73 ± 6.97 and 15.03 ± 1.04, respectively. And 29.02 ± 2.65; 38.14 ± 5.43 and 14.48 ± 1.19 was the mean age at first service (AFS), age at first calving (AFC) and calving interval (CI) of crossbred cows, respectively in the study area. All the reproduction parameters included in this study were significantly different at (P<0.05) between breeds. Moreover, 1.18 ± 0.52 and 5.83 ± 0.28 liters were the daily milk yield of local and crossbred dairy cows, respectively. The indigenous dairy cow has 7.15 ± 0.13 months of lactation length, whereas 8.87 ± 0.18 months were the lactation length of crossbred dairy cow. Comparing with the recommended standard, the dairy cows of the study area were familiarized with poor reproductive and productive potential. Thus, the benefits derived from dairy cows were not commensurate with their number. Since genetic improvement of livestock has a major impact on animal productivity and reproductively, its effects are permanent, cumulative and usually highly cost effective; practicing advanced breeding methods (cross breeding though AI and sound estrus detection), upgrading genetic makeup of the animal (crossing local with Holstein Friesian) and practicing good management system in the study area is highly needed.
Anthelmintic effect of betel nut (Areca catechu) and neem (Azadirachta indica) extract against liver fluke (Fasciola spp.)

Objective: This study aimed to measure the anthelmintic effects of betel nut (Areca catechu) and neem (Azadirachta indica) leaf extracts against Fasciola spp. in vitro in comparison with the commercial dewormer, Albendazole, and the negative control, nutrient broth. The study determined the extract concentration that produced the highest efficacy based on the average recorded mean motility time, gross, and microscopic changes of the flukes treated with different concentrations of plant extracts. Material and Methods: The study consisted of eight treatments. Every treatment consisted of 10%, 20%, and 40% concentrations of both betel nut extract (BNE) and neem leaf extracts, positive control treatment (Albendazole-treated) and negative control treatment (25 ml nutrient broth). The motility of the flukes on all treatments was based on the established motility criteria scoring. The flukes subjected to all treatments were processed for histopathological analysis. Results: The result of the study revealed that after exposure of Fasciola spp. under 10%, 20%, and 40% extract concentrations, betel nut showed higher efficacy having the recorded mean motility time of 0.22, 0.07 min, and no movement upon contact, respectively, than Albendazole which produced mean motility time of 0.38 min. Nevertheless, the flukes treated with 10%, 20%, and 40% neem leaf extracts obtained the average mean motility time of 220, 151, and 98 min, respectively. Conclusions: The results gathered showed that 40% BNE concentration showed the highest efficacy based on the recorded mean motility time. All treatments of betel nut extract evidently showed marked changes in the gross and microscopic morphology of the flukes. However, the neem extract was ineffective in all concentrations although changes were observed microscopically. Furthermore, the nutrient broth was proven to be effective as a culture medium since the flukes remained active until 8 h of exposure.
Distributed Dynamic Clustering Algorithm for Formation of Heterogeneous Virtual Power Plants Based on Power Requirements

Real-time distributed clustering algorithm for aggregation of distributed energy storage systems into heterogeneous virtual power plants is proposed. Two types of virtual power plants are formed: one for provisioning the bulk (low-frequency) power demand and one for provisioning the high-frequency power demand. The proposed distributed clustering algorithm determines the virtual power plants’ memberships, for each distributed energy storage system, based on each energy storage system’s capacity and owner’s willingness to participate in one of the virtual power plants. The proposed distributed secondary level control system regulates each energy storage system according to each virtual power plant’s operational objectives. Specifically, a balanced state of charge of all energy storage systems inside each virtual power plant is maintained. One of the virtual power plants is responsible for the frequency and voltage regulation by providing the required high-frequency power, while the other one provides the required bulk (low-frequency) power demand. In addition, the proposed clustering algorithm enables to meet a required energy capacity of the bulk virtual power plant by automatically tuning the clustering algorithm parameters. RTDS real-time technique verifies the proposed clustering algorithm and control systems on the IEEE 13 nodes power system with distributed energy storage systems and photovoltaic sources. The presented results demonstrate dynamic aggregation of energy storage systems into heterogeneous virtual power plants based on power demand while all regulation requirements are met.
Production of cellulose nanostructures from Chilean bamboo, Chusquea quila

In Chile, bamboo bushes of Chusquea quila genus (or popularly known as ‘quila’) have brought economic and ecological problems for decades in the south-central part of this country. On the other hand, this plant species was studied as a raw material for the production of nanofibrillated cellulose (CNF) and nanocrystalline cellulose (CNC), presenting an opportunity for sustainable and environmentally friendly management, positioning Chile as a Latin American country at the forefront of studies with nanotechnological approaches. The methodology applied to generate these nanostructures contemplated hydrolysis with sulfuric acid and oxalic acid, in addition to an intermediate stage of microfluidization to generate nanofibrillated cellulose. The products obtained showed morphological and topographic homogeneity in the scanning electron microscopy (SEM) and atomic force microscopy (AFM) images. The diameter values of the particles ranged from 10 to 20 nanometers for the CNCs. Through Fourier transformed spectrophotometry (FTIR) it was found that the processes of microfluidization and acid hydrolysis did not affect the molecular shape of the nanostructures and X-ray diffraction (XRD) was important to determine crystallinity index (IC), presenting values higher than 80%.
