Simultaneous diversification of Polypodiales and angiosperms in the Mesozoic

Comprising about 82% of the extant fern species diversity, Polypodiales are generally believed to have diversified in the Late Cretaceous. We estimated the divergence times of Polypodiales using both penalized likelihood and Bayesian methods, based on a dataset consisting of 208 plastomes representing all 28 families and 14 fossil constraints reflecting current interpretations of fossil record. Our plastome phylogeny recovered the same six major lineages as a recent nuclear phylogeny, but the position of Dennstaedtiineae was different. The present phylogeny showed high resolution of relationships among the families of Polypodiales, especially among those forming the Aspleniineae. The divergence time estimates supported the most recent common ancestor of Polypodiales and its closest relative dating back to the Triassic, establishment of the major lineages in the Jurassic, and a likely accelerated radiation during the late Jurassic and the Early Cretaceous. The estimated divergence patterns of Polypodiales and angiosperms converge to a scenario in which their main lineages were established simultaneously shortly before the onset of the Cretaceous Terrestrial Revolution, and further suggest a pre‐Cretaceous hidden history for both lineages. The pattern of simultaneous diversifications shown here elucidate an important gap in our understanding of the Terrestrial Revolution that shaped today’s ecosystems.
Özel Eğitim Öğretmeni Adaylarının İş Birliğine İlişkin Metaforik Algıları

Special education is a field that requires special education teachers to collaborate frequently with specialists from different fields due to the individual differences of the students. This study examined the metaphorical perceptions of preservice special education teachers about collaboration, as well as the reasons for the metaphors they created. The study examined metaphors created by 93 special education teachers prior to collaborating, and their reasons. Metaphoric Perception Survey, created by researchers, was used for data collection. The questionnaire has a semistructured question such as “Collaboration in special education . ”. Because . ". At the end of the study, the preservice special education teachers' structure in five different themes, the structure of the collaboration, the threats to collaboration, the requirements of the collaboration, the importance of the collaboration and the purpose of the collaboration.
Improving polytechnic students’ high-order-thinking-skills through inquiry-based learning in mathematics classroom

Mathematics is one of the most emphasized subjects and has grown immensely to provide a strong base for programs in science, engineering and technology. Training students in this field will give them the opportunity to improve their high order thinking skills (HOTS). But the students’ HOTS level is at low stage due to the learning approaches employed in classrooms. The aim of this study is therefore to investigate the effect of inquiry-based learning (IBL) in improving polytechnic students’ level of HOTS. In this study, pre-test-post-test quasi-experimental design was used involving two purposefully sampled National Diploma II classes. Seventy-three students participated in this study (36 students for experimental group and 37 students for control group). HOTS questions and worksheets based on IBL are the instruments used for this study. The findings of independent-sample t-test analysis showed that there was a significant difference between the mean scores of post-test for both experimental and control groups at alpha= 0.05 (p= 0.000) level of significant. Moreover, it was found that the students’ overall HOTS level (applying, analyzing, evaluating, and creating) can be improved through this approach. In conclusion, IBL can have a positive effect on the HOTS of polytechnic students in mathematics classroom.
Pollen collected and trophic interactions between stingless bees of the genera Melipona, Frieseomelitta and Plebeia (Apidae: Meliponini) raised in Central Amazon

Bees of the Meliponini tribe are the most diverse group of social bees in the world and their need for trophic resources (pollen and nectar) makes them the main floral visitors and consequently the main pollinators of tropical forests. The trophic resources of stingless bees of the genera Melipona, Frieseomelitta and Plebeia (Apidae: Meliponini) were studied during the dry season of 2016 and rainy season of 2017 in the meliponary “Sucupira” located east of Manaus-AM (03°00’05” and S, 59°51’ 05 W). The most representative botanical families in this study, both in the dry and rainy seasons, were: Melastomataceae, Fabaceae, Anacardiaceae, and Arecaceae. The highest levels of diversity and uniformity of collected pollen types were observed for Friseomelitta sp. (H’=2.318; J’=0.712) in the rainy season, followed by F. varia (H = 2.044 and J’= 0.607) in the dry season. Even with their unique preferences, the bees presented a high degree of nestedness, both for presence and absence data (30.47; p < 0.001) and quantitative data (30.75; p= <0.001). Despite the richness of resources collected (87 pollen types), the results indicate that some botanical groups form the basis of these bees' diets, which justifies the trophic relations indicated by the high network nestedness.
Photosynthetic Product Allocations to the Organs of Pinus massoniana Are Not Affected by Differences in Synthesis or Temporal Variations in Translocation Rates

Photosynthesis and the allocation of photosynthetic products are the two main factors that determine plant growth. To understand the growth and productivity of Pinus massoniana Lamb. , the diurnal changes in photosynthetic rate were continuously monitored. Furthermore, the translocation and allocation of the photosynthetic products synthesized in the morning and afternoon were explored using 13C pulse labeling. The results showed that: (1) on sunny days, the diurnal variation of the net photosynthetic rate showed a “double peak” curve, with an obvious “a depression” when temperatures were highest and humidity lowest. On cloudy days, it showed an irregular “jagged” curve, which was curve consistent with the variations in photosynthetically active radiation (PAR). Meanwhile, the photosynthetic rate changed with the transient changes in environmental factors such as PAR, temperature, and humidity. (2) The mean value of the net photosynthetic rate in the morning was higher than in the afternoon, and the response of the net photosynthetic rate to environmental change (PAR, temperature, humidity, and CO2 concentration) in the morning was greater than that in the afternoon. (3) The translocation of photosynthetic products synthesized in the afternoon was faster than that in the morning. Shortly after synthesis of photosynthetic products, the translocation of products synthesized in the morning tended toward upper organs (including current-year leaves and 1-year leaves), while the translocation of products synthesized in the afternoon decreased in the upper organs. However, after 15 days of 13C pulse labeling, the allocation of the photosynthetic products synthesized in the morning and afternoon tended to be the same. These results indicate that the differences in the photosynthetic products synthesized and the temporal differences in the translocation rates did not affect the final allocation of the photosynthetic products in the various organs of the P. massoniana. These results improve our knowledge of the functional phases of P. massoniana during the diurnal cycle.
Fault tolerance strategy to increase Moodle service reliability

Moodle is one of online Learning Management System that can be downloaded and installed on our server for free. Moodle is suitable solution for universities to organize online learning. Changing all learning activities from offline to online during a pandemic situation, especially for universities, requires Moodle services to be reliably available. The more students it means the more traffic should be handled by Moodle server. Moodle consists of system, user’s data and a database. To increase Moodle reliability, we can rely on these components. We can use virtualization technology to simplify migration system and recovery process. Distributed file system technology is a best solution to store Moodle user data because it can be replicated into several nodes and support for high availability. Finally, the last component of Moodle is a database, we can replicate the database into several machine to increase availability. At the top of every Moodle component, we need cluster control to make sure all of Moodle components can be accessed. The results show that with the right fault tolerance strategy, all requests can be responded to 100% without error. In addition, this strategy can also increase the response time 12 times faster when compared to a single server.
A Novel Agarwood Resin Inducement Method Using Mycotoxins of Selected Fungal Species

Agarwood is a dark, fragrant, valuable resinous wood produced in Aquilaria and Gyrinops tree species in the family Thymelaeaceae to protect internal tissues from microbial infections. Aspergillus niger and Fusarium solani are well known to induce agarwood resin formation. This study demonstrated for the first time that agarwood resin formation can be induced by the mycotoxins of A. niger and F. solani. Different volumes of mycotoxins extracted from the ASP-U strain (USJCC-0059) of A. niger and the FUS-U strain (USJCC-0060) of F. solani were inoculated into A. crassna trees at 1 m intervals. The impacts of the inoculations were observed through resin content and constituent analysis at 7 months after inoculation. Resin production due to the mycotoxins of ASP-U and FUS-U was restricted to ±20 cm and ±60 cm, respectively, from the inoculation point. Color of the resinous agarwood varied from yellowish-brown to black. The differences in resin content formation due to the different inoculant volumes of ASP-U and FUS-U were statistically significant, and the average resin contents varied from 0.89%-4.44% and 1.24%-9.20%, respectively. GC-MS analysis detected 27 constituents responsible for the characteristic aroma of agarwood resin. Among them, phenyl butanone, agarofuran, agarospirol, β-caryophyllene, alloaromadendrene oxide and (-)guaiene-1(10),11-diene-15-ol were found in all extracts. These are common in commercially available agarwood induced by fungal species. Hence, we demonstrated that the mycotoxins of specific fungal strains can be used for agarwood production. Therefore, chemically synthesized mycotoxins can be used at commercial-scale, eliminating the difficulties of maintaining live fungal cultures for agarwood production.
Bringing the developmental state back in: explaining South Korea’s successful management of COVID-19

Abstract South Korea had the largest number of confirmed cases of COVID-19 after China by February 2020. This situation changed dramatically in less than two months as it effectively managed the pandemic without imposing a nationwide lockdown. Furthermore, Korean pharmaceutical companies quickly manufactured sufficient test-kits and other COVID-19 essential medical devices to meet domestic demand and exported them to more than one hundred countries, including developed countries, amid global shortages. What explains South Korea’s success story? Drawing on the developmental state concept, I argue that South Korea’s success story can be attributed to 1) the early creation of a health official-led pilot agency; 2) the government’s intervention for rapid production and export of medical equipment; 3) the distinct state-society relations. In doing so, contrary to the declinist literature, this study reveals that the Korean state’s institutional capacity has not declined. It also illustrates that the developmental state seems to be an effective system in dealing with a pandemic and promoting economic activities during the crisis. However, it is yet to be seen how Korea will deal with future challenges arising from the new wave. This study also suggests how the Global South can learn lessons from the South Korean experience.
Augmenting a socio-hydrological flood risk model for companies with process-oriented loss estimation

ABSTRACT Socio-hydrological flood risk models describe the temporal co-evolution of coupled human–flood systems. However, most models oversimplify the flood loss processes and do not consider companies’ substantial contribution to total losses. This work presents a socio-hydrological flood risk model for companies that focuses on changes in vulnerability. In addition, we augment the socio-hydrological model with a process-oriented, sector-specific loss model in order to capture damage processes more realistically. In a case study, we simulate the historical flood risk dynamics of companies in the floodplain of Dresden, Germany, over the course of 120 years. Our analysis suggests that the companies in Dresden increase their exposure more cautiously than private households and decrease their vulnerability more actively through private precaution. The augmentation, consisting of informative predictors, a refined probabilistic model, and the incorporation of additional data, improves the accuracy and reliability of the flood loss estimates and reduces their uncertainty.
Financial pre-factors for post-performance of cross-border mergers & acquisitions

ABSTRACT We study mergers and acquisitions (M&A) when one company is Chinese and another company is outside China. Previous studies are still much lacking considerations on financial factors affecting subsequent performance of such multinational (or ‘cross-border’) M&A. Here, a few (5) influencing factors are tested through a multiple linear regression model for 100 listed companies over [2016–2018]. We examine the role of (i) the mode of payment, (ii) cultural differences, (iii) industry differences, (iv) company scale and (v) the shareholding ratio. The research denotes that the payment method and the shareholding ratio of the largest shareholder have both a positive correlation with the performance in the year of the M&A and in the following one, – whatever the industries differences and companies sizes.
Atomistic simulation study of the adsorptive separation of hydrogen sulphide/alkane mixtures on all-silica zeolites

ABSTRACT The selective separation of the aggressive hydrogen sulphide gas from industrial streams is highly important from environmental and economic aspects. Capture of this substance from industrial gases of light hydrocarbons by all-silica zeolites can be an eco-friendly alternative to the other common absorption/adsorption procedures. The adsorption from binary mixtures of hydrogen sulphide and light alkanes (H2S/CH4, H2S/C2H6, and H2S/C3H8) on preselected all-silica zeolites was studied by atomistic simulations, using a recently developed force field for hydrogen sulphide. In addition to four experimental all-silica zeolite frameworks (DDR, CHA, ACO, CAS), three of their hypothetical relatives were also drawn into the investigations. The smaller pore size zeolites (ACO, CAS, and particularly one of the hypothetical zeolites) showed remarkable separation performances under real ambient conditions. Among the examined structural details of the studied frameworks, the calculated realistic pore size distributions proved the most appropriate in attempts to unravel the connection between adsorption selectivities and framework structural properties. The investigations were completed by a necessary demonstration of the translational accessibility of the inner cages of the smaller pore size zeolites.

Bioactivity of Moringa oleifera and Ruta angustifolia Oils on Spodoptera littoralis (Boisd.) Moths’ Vitality

Spodoptera littoralis, cotton leafworm is a destructive pest for several economic crops. The more use of chemical pesticide the more increase of this pest resistance, that lead to discovering new natural pesticides from plant extracts and oils. The present search is targeted to suggest alternative components from natural sources that more safety to the ecosystem and had the ability to reduce insect prohibition. The experimental results exhibited highly significance effect on adult moths’ vitality aspects with the pre-pupal treatments by Moringa oleifera and Ruta angustifolia at all tested concentration especially 4% concentration as shorten female moths' longevity and reduced the oviposition period. Obviously, moringa recorded the shortest oviposition period (3.00 days) while ruta oil recorded (5.33 days) compared to control (10.66 days). Significantly reduced fecundity and hatchability and increased the sterility% compared to control. The tested plant oils caused severe ovarian and testicular histological deformation and significant increase in total lipids and total carbohydrate contents also, marked DNA fragmentation in variable levels in ovaries and testes in each oil treatments at 4% concentration. The promising results of both oils on S. littoralis reproductive system can prove them be used in the integrated management programs of this pest.
The Effect of Cognitive Behavioral Therapy on Self-Management and Self-Care Behaviors of Type 2 Diabetes Mellitus Patients

Diabetes mellitus (DM) is the condition of metabolism affected by chronic hyperglycemia (the increase of glucose levels in the blood) caused by insulin secretion defect. One of the non-pharmacological therapies used to decrease the type 2 DM is cognitive behavioral therapy. The objective of the research was to identify the effect of Cognitive Behavior Therapy (CBT) on self management and self-care behaviors of type 2 DM patients. The research used a quasi-experimental method with a two-group pretest-posttest design. The samples were 70 respondents with 35 of them were in the intervention group and the other 35 were in the control group, taken by using a consecutive sampling technique. The data were gathered using the Diabetes Self-Management Questionnaires (DSMQ) and the Summary of Diabetes Self-Care Activities (SDSCA) questionnaires. The gathered data were analyzed by using paired t-test, and independent t-test. The results of the study showed that there were significantly differences of mean scores of self management and self care behaviors between intervention and control groups (t=13.24; p=0.00) and(t=14.63,p=0.00), respectively. It is recommended that cognitive behavior therapy can be used as one of the non-pharmacological therapiesto change self-care behaviors in type 2 DM patients.
Systemic Risk and Collateral Adequacy: Evidence from the Futures Market

Abstract Conventional collateral requirements for derivatives are conservative, but not explicitly designed to buffer systemic risk. I explore collateral adequacy against systemic risk in the Canadian futures market during the 2008 crisis. I find that conventional collateral levels adequately absorb systemic risk, even allowing for an implausibly high level of stress, and that systemic risk spillovers do not exceed the effect of an approximately 1% downward stock price move. I also document that the largest systemic risk contributors are buffered relatively less than the rest, and that there is a large cross-country difference in the behavior of U.S. and Canadian institutions.
Landslide Susceptibility Mapping of Central and Western Greece, Combining NGI and WoE Methods, with Remote Sensing and Ground Truth Data

The exploitation of remote sensing techniques has substantially improved pre- and post- disaster landslide management over the last decade. A variety of landslide susceptibility methods exists, with capabilities and limitations related to scale and spatial accuracy issues, as well as data availability. The Interferometric Synthetic Aperture Radar (InSAR) capabilities have significantly contributed to the detection, monitoring, and mapping of landslide phenomena. The present study aims to point out the contribution of InSAR data in landslide detection and to evaluate two different scale landslide models by comparing a heuristic to a statistical method for the rainfall-induced landslide hazard assessment. Aiming to include areas with both high and low landslide occurrence frequencies, the study area covers a large part of the Aetolia–Acarnania and Evritania prefectures, Central and Western Greece. The landslide susceptibility product provided from the weights of evidence (WoE) method proved more accurate, benefitting from the expert opinion and the landslide inventory. On the other hand, the Norwegian Geological Institute (NGI) methodology has the edge on its immediate implementation, with minimum data requirements. Finally, it was proved that using sequential SAR image acquisitions gives the benefit of an updated landslide inventory, resulting in the generation of, on request, updated landslide susceptibility maps.
Oral Exams: A More Meaningful Assessment of Students’ Understanding

Abstract Compared to their written counterpart, oral assessments provide a wealth of information about student understanding. Instead of deciphering a static response, oral assessments provide instructors the opportunity to probe student explanations, obtaining a more complete picture of their understanding. Moreover, students explaining their conceptual reasoning is advocated in the 2016 GAISE guidelines. Additionally, oral exams allow for flexibility in how students can explain their thinking, potentially helping build students’ identities as statistical thinkers and speakers. Despite the facilities these assessments provide, oral assessments are rarely used in the statistics classroom. In this article I describe the important considerations to be attended to when implementing oral exams in the classroom, my experiences facilitating oral exams in my statistics courses, and some lessons I learned along the way. Supplementary materials for this article are available online.
Lenses and Spectacles to Prevent Myopia Worsening in Children

A total of 5 relevant systematic reviews and 7 randomized controlled trials (RCTs) were identified. Myopia progression and axial length elongation was less with omafilcon A (MiSight) contact lenses compared to single-vision lenses (1 RCT; statistical significance of difference was not reported). Myopia progression and axial length elongation was less with defocus incorporated multiple segments spectacle lenses compared to single-vision spectacle lenses (1 RCT; the between-group difference was statistically significant). Myopia progression was less with orthokeratology contact lenses compared to single-vision contact lenses or single-vision lenses (2 systematic reviews and 2 RCTs; between-group difference was statistically significant or statistical significance was not reported) and axial length elongation was less (5 systematic reviews and 2 RCTs; between-group difference was statistically significant or statistical significance was not reported). Myopia progression and axial length elongation was less with multifocal lenses compared with single-vision contact lenses (1 systematic review and 2 RCTs; between-group difference was statistically significant). Findings need to be interpreted in the light of limitations, such as limited quantity and quality of the included primary studies, limited information regarding adverse events, and lack of long-term data. No economic evaluations reporting on the cost-effectiveness of these interventions were identified.
