Published: January 2021

The propagation, extraction, and antibacterial studies of Azolla pinnata were carried out in this study. The propagation involved two fertilizers, which were chicken manure and inorganic AB fertilizer. The dry yield was extracted using two methods, which were Soxhlet and supercritical fluid extraction (SFE). Methanolic extracts were obtained and subjected to several antibacterial tests, which include the disk diffusion assay, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests, against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The results showed that AB fertilizer produced more dry yield compared to chicken manure. The extract yield from Soxhlet exhibited a higher yield than that of SFE, recording its highest at 21.20%. The findings of antibacterial tests revealed that all extracts inhibited the growth of B. subtilis and S. aureus, but none showed inhibition against E. coli and P. aeruginosa. The largest diameter of inhibition zone of 2.67 ± 1.53 mm was obtained by E2 (CM-SFE), with a MIC value of 0.125 mg/mL against B. subtilis. High MBC values further confirm that the mechanism of inhibition against B. subtilis and S. aureus were due to the bacteriostatic properties of the extracts tested.

Published: January 2021

Blooms of toxic Alexandrium tamiyavnichii have been recorded in several parts of the world including Malaysia. This Harmful algal bloom (HAB) has led to human illness and loss to fishery industries. In order to control the bloom and minimize the effects, the growth of the species needs to be inhibited using a mitigation agent, preferably environment friendly agent. In this study, an ornamental plant, Sansevieria trifasciata will be used to inhibit the growth of A. tamiyavanichii. The plants were fractionated to obtain fractions (dichloromethane (DCM) and methanol) from ethanol fresh and dried plants extracts. Eight concentrations (0.001, 0.01, 0.1, 0.5, 1.0, 1.5, 2.0 and 2.5 mg/mL) of these fractions were tested on the algae for 24 hours and removal efficiencies (RE) were determined. Toxicity test was conducted on Artemia using 10, 50, 100 and 500 mg/mL concentrations of active fractions for 24 hours. Phytochemical compounds were detected using standard procedures. Results obtained showed that the growth of A. tamiyavanichii was inhibited by all concentration tested. Active fractions from DCM using both fresh and dried plants showed good results with more that 80% RE values at 5 mg/mL within 2.5 to 5 hours. During the experiments, DCM used did not change the pH of the culture medium compared to methanol fraction. For phytochemical screening tests, compounds detected in all fractions were alkaloids, tannins, glycosides, reducing sugars and terpenoids. These compounds might cause the inhibition of targeted algae, however further study is needed to determine the bioactivity and its specific effect on HAB species. To conclude, fractions of DCM from fresh and dried S. trifasciata have the potential in the mitigation of A. tamiyavanichii. This could help to minimize the impact of this species on human health and reduce the loss to fishery industries.

Authors: Beteta-Avio Ramón
Published: January 2021

Resumen
Se analizan de forma sincrónica los años de sobremortalidad registrados en la población de Siles en el siglo XX. Se observan los factores epidemiológicos, socioeconómicos y ambientales que han podido generarlas. Para hallar los años de sobremortalidad y su intensidad se aplican los métodos de Del Panta y Livi-Bacci y el de Flinn. La mayoría de las crisis se manifiestan locales, mixtas y con intensidad pequeña. Se diferencian claramente dos categorías: las registradas hasta la del año 1941 y las acontecidas a partir de 1968. Entre ambas categorías se manifiestan notables diferencias en las condiciones de vida de la población, las causas de mortalidad, la edad de los fallecidos y la estacionalidad.

Desde Richard de Bury (1344) hasta Charles Lyell (1830). Algunas consideraciones históricas sobre el uso del término ‘geología’
Authors: García-Cruz Cándido Manuel
Published: January 2021

Resumen
La primera referencia que hay sobre el uso del término geología se encuentra en Richard de Bury, a mediados del siglo XIV, aunque no llegó a definirla. A lo largo de casi quinientos años, numerosos autores han utilizado este vocablo, entre ellos U. Aldrovandi (1603), M. P. Escholt (1657), R. Lovell (1661), F. Sessa (1687), E. Warren (1690), D. Clüver (1700), B. Martin (1735), J.-A. de Luc (1778), o H. B. de Saussure (1779), sin precisar totalmente su significado, con una gran vaguedad conceptual y sin definir claramente su materia de estudio: Geología como título de algunas obras, o ideas como sobre lo excavado de la tierra, discurso sobre la tierra, doctrina general del globo, o ciencia de los continentes, no fueron desarrolladas o explicadas adecuadamente por sus autores. Entre los padres de la geología como ciencia, un significado implícito de acuerdo con el contenido de sus obras se encuentra en G. Arduino (1760) y J. Hutton (1795), así como en otros naturalistas como B. Faujas de Saint-Fond (1803). En las primeras décadas del siglo XIX, S. Breislak (1811) y W. Phillips (1815) definieron los aspectos descriptivo, histórico y explicativo de la geología, y años más tarde C. Lyell (1830) estableció con precisión el alcance de la geología como ciencia histórica, con una metodología basada en el Actualismo-Uniformitarismo.

The first reference about the use of the term geology is found in Richard de Bury, in the mid-fourteenth century, although he did not define it. This word has been used over almost five hundred years by numerous authors, including U. Aldrovandi (1603), M. P. Escholt (1657), R. Lovell (1661), F. Sessa (1687), E. Warren (1690), D. Clüver (1700), B. Martin (1735), J.-A. de Luc (1778), and H. B. de Saussure (1779), without fully specifying its meaning, with a great vagueness as a concept, and without clearly defining its subject matter: Geology as some book titles, or ideas such as on what is dug out of the earth, discourse concerning the earth, general doctrine of the earth, or science of continents, were duly neither developed nor explained by the authors. Among the fathers of geology as a science, according to their works contents, an implicit meaning is found in G. Arduino (1760) and J. Hutton (1795), and also in other naturalists as B. Faujas de Saint-Fond (1803). In the first decades of the nineteenth century, S. Breislak (1811) and W. Phillips (1815) defined the descriptive, historical and explanatory aspects of geology, and C. Lyell (1830) laid down accurately the scope and aim of geology as a historical science, with a methodology based on Actualism-Uniformitarianism.

Published: January 2021

This paper discusses the impact caused by a virus outbreak called coronavirus disease (COVID-19). The virus initially appeared in Wuhan, China, in late 2019, then spread throughout the world, including the Asia-Pacific Region (APR). COVID-19 is believed to have damaged health and the global economy. Unlike the crisis that was caused by many previous disruptions, the impact caused by COVID-19 is wider and bigger. Many economic sectors have been paralyzed and suffered losses, such as production and trade. Export-import cooperation has become a dependency between countries, and this has also been hampered due to the rapid spread of this pandemic. Then, the closure of transportation access and the suggestion to stay at home has made the tourism sector sluggish. Meanwhile, another effect of this pandemic is the emergence of new poor groups due to the rise in layoffs. This study uses qualitative research methods to search for theoretical references relevant to cases or problems found in various works of literature, mainly scientific journals, books, reports, and actual and trusted news on the internet. This study aims to explore the potential of COVID-19 that not only threatens health, but also social, political, and economic spheres. From the analysis, it was concluded that COVID-19 could inhibit all global socio- economic activities that threaten the success of realizing Sustainable Development Goals (SDGs), but on the other hand, this pandemic can also be momentum for a more sustainable life order.

In the Concept of the New Ukrainian School, the main task of a modern secondary school is the education of conscious citizens of Ukraine, providing conditions for creative self-realization and self-determination of the individual. Changes and updates of the educational paradigm bring teachers to a modern understanding of the educational process as an activity based on self-development, self-improvement and their pedagogical support. It involves subject-object interaction in the educational space of the secondary school. One of its important components is the pedagogical conditions, compliance with which depends on the effectiveness of achieving the educational goal. The study of this problem is carried out in several areas: the role of pedagogical conditions for the formation and development of the personality of both the teacher and the subject to which the learning process is directed; organization, activation and modernization of subject training. The analysis allows us to state that the modern understanding of the concept of "pedagogical conditions" is complicated by the variety of research areas of scientists. Analysis of pedagogical, psychological and philosophical scientific literature shows that the problem of substantive and substantive analysis of the concept of pedagogical conditions is considered by scientists from different aspects. In the context of our study, we define pedagogical conditions as features of the organization of the educational process in a secondary school, which determine the results of upbringing, education and development of the student's personality, objectively ensuring the possibility of achieving them. In the course of our research the levels of pedagogical conditions were determined. Thus, considering the concept of pedagogical conditions in the context of educational activities of a secondary school, we came to the conclusion that pedagogical conditions are a qualitative characteristic of the main factors, processes and phenomena of the educational environment. Research in the direction of development of technologies of creation of optimum pedagogical conditions for the decision of certain problems of educational activity of comprehensive school is perspective.

The article discusses a methodological approach to solving problems when studying the topic «Harmonic oscillations» in the course of general physics using the Mathcad software package when training specialists in engineering specialties. In the course of the research, the scientific literature was theoretically analyzed, the experience of using teaching methods was studied. The methodological basis of the research is an integrated approach that combines traditional forms of teaching and learning using the Mathcad software package. An illustrative principle of teaching and presenting information is given on the example of two tasks to demonstrate the capabilities of the Mathcad software package in the classroom in higher education institutions. The considered examples are given in general form without numerical calculations, when supplemented with numerical values and changing the initial conditions, it is possible to increase the number of possible tasks based on the given templates. The methodical approach is introduced into the educational process. As a result of observation of the lessons, the results obtained were summarized and systematized. It is proposed to supplement the solution of these problems with the help of computer modeling with an analytical solution for comparing and checking the results obtained. The introduction of the proposed methodological approach into the educational process demonstrates an increase in students' motivation to master the discipline as a whole; the acquisition by students of the skills of using computer programs to solve professionally oriented problems; presentation of educational material in a visual form; saving study time, etc. Solving problems of applied content encourages students to independently establish intersubject connections in natural-mathematical and special disciplines at different levels and contributes to the transfer of knowledge from one field of science to another. The approach used encourages students to independently model oscillating processes to study the operation of various devices and structures. Using the considered methodology for solving the above examples in the Mathcad environment, students can master not only mathematical competencies, but also additionally related to information processing; to gain the skills of analysis and search for optimal solutions, which is inherent in engineering specialties.

According to a group of Stanford scientists, mealworms, the larva of darkling beetles, can digest Styrofoam, a type of polystyrene, and break it down into carbon dioxide. This paper investigates the plastic-digesting property of mealworms on different types of plastic, namely polystyrene (PS), low- density polyethylene (LDPE) and polyvinyl chloride (PVC). Since mealworms breathe in oxygen and exhale carbon dioxide. To measure the extent of plastic intake, we explored an alternative method to measure the extent of plastic digestion - using Arduino carbon dioxide sensors instead of calculating the difference in weight of plastic. As the increase in the exhalation of carbon dioxide is indicative of the amount of plastic consumed, the authors measured the change in carbon dioxide concentration of the mealworms' environment as they consume plastic. This is put into comparison with when the mealworms respire without food. The results show that mealworms consume Styrofoam to a certain extent. However, they are mostly unable to digest polyethylene and polyvinyl chloride, likely due to their elasticity and high density respectively.

Measures that produce valid and reliable antenatal depressive symptom scores in low resource country contexts are important for research efforts to better understand risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates cross-country analysis of similarities and differences across contexts. To date, however, very few studies have evaluated the psychometric properties and comparability of widely used antenatal depressive symptom measures across diverse cultural, political and social contexts. To address this gap, we used data from the Evidence for Better Lives Study – Foundational Research (EBLS-FR) to examine the reliability, validity, and cross-country invariance of the 9-item version of the Patient Health Questionnaire (PHQ-9) in antenatal samples across eight low- and middle-income countries (LMICs). We found that the PHQ-9 scores had good internal consistency and construct validity across all eight countries. However, in measurement invariance analyses, only partial metric invariance held and only across four of the countries. Further, there were some notable between-site contrasts in the nomological networks of PHQ-9 scores. Our results suggest that the PHQ-9 yields reliable scores when administered in antenatal populations; however, the meaning of the scores varies by country. Thus, interpretation of PHQ scores should consider local meanings of depression to ensure that local conceptualisations and manifestations of antenatal depressive symptoms are adequately reflected.

Zusammenfassung: Berichtet wird die Konstruktion und Überprüfung einer deutschsprachigen Adaption des Fragebogens „Student Evaluation of Educational Quality“ (SEEQ) von Marsh (1982, 2007), ein umfassend überprüftes und international etabliertes Instrument zur Erfassung von Studierendenurteilen der Lehrqualität. Es wurde übersetzt, geringfügig erweitert und anhand einer Stichprobe von 76 687 Studierendenurteilen zu 3 660 Lehrveranstaltungen überprüft. Interne Konsistenzen und Intraklassenkorrelationen indizierten eine hohe Messgenauigkeit. Faktorenanalysen bestätigten die im SEEQ unterschiedenen Dimensionen. Neben den Produktfaktoren (Lernzuwachs, Gesamtbeurteilung) ließen sich als Faktoren des Lehrhandelns Engagement, Stoffstrukturierung und -präsentation, Aktivierung der Studierenden, Sozialklima, Stoffbreite, Leistungsbewertung und Aufgaben wie im Originalinstrument unterscheiden. Mit der Adaption wird studentische Beiträge als optionaler Faktor vorgeschlagen. Das Instrument erwies sich als messinvariant über verschiedene Veranstaltungsformen hinweg. Insgesamt legen die Ergebnisse nahe, dass mit der deutschsprachigen Adaption des SEEQ die Qualität hochschulischer Lehre international anschlussfähig und mit hoher Güte erfasst werden kann. Construction and Confirmation of a German Adaption of the Student Evaluation of Educational Quality Questionnaire (SEEQ) Abstract: The Student Evaluation of Educational Quality Questionnaire (SEEQ) by Marsh (1982, 2007) was adapted to German and tested using assessments from 76,687 students in 3,660 university courses. Internal consistencies and intraclass correlations indicted a high reliability. Two-level CFAs and ESEM analyses confirmed the separability of all original SEEQ dimensions: learning and overall as product factors, and enthusiasm, organization / clarity, group interaction, individual rapport, breadth, examinations / grading, and assignments / readings as factors on the level of instructional behaviors. In this adaption, we additionally proposed student contributions as an optional factor (the extent to which contributions of fellow students are considered helpful, and whether they are effectively controlled by the instructor), especially for contexts – such as those found in Germany – where student-directed teaching methods are prevalent. Additionally, we expanded the overall course rating by adding two items using a grade scale. These two adaptions are optional, and the scale worked equally well without them. We could confirm measurement invariance across different types of courses. Taken together, our findings indicate that the German adaption of the SEEQ measures teaching quality in accordance with established testing standards

Adolescents are often described as notorious risk-takers. However, adolescents do not always take risks and risk-taking may vary across risk-taking domains. Furthermore, there are large individual differences. Certain clinical groups, such as adolescents with ADHD, may be more likely to take risks. In two studies we examined these domain-specific and individual differences using the adolescent Domain-Specific Risk-Taking (DOSPERT)-questionnaire, which assesses adolescents’ self-reported risk-taking likelihood, perceptions of risk, and perceptions of benefits (‘returns’). Furthermore, we examined how risk-taking likelihood is informed by risk- and benefit-perceptions, i.e., ‘risk-return’ weighing. In a community-sample study (N=361, 12-25 years), we tested the domain-specificity across age, and observed a peak in risk-taking likelihood in late adolescence in the Health-Safety domain only. Perceived benefits were heightened, and perceived risks attenuated, in mid-to-late adolescence for Health-Safety, Recreational, and Ethical risks. In a second study, we compared boys with ADHD (N=81) and controls (N=99; 12-20 years). Adolescents with ADHD rated higher risk-taking likelihoods for Social risks only. Risk-return models in both studies revealed that effects of perceived risks (Health-Safety) and benefits (Recreational) on risk-taking likelihood were most pronounced and varied across age. Together, adolescents’ risk-taking likelihood is impacted by risks and returns, age-related differences, and should be studied domain-specifically.
Age and Workplace Deviance: A Meta-Analytic Test of Two Mediating Mechanisms

In the current meta-analysis, we examine the relation between age and workplace deviance, and find a small but significant negative correlation (rho = -.092, k = 198). More importantly, we test two complementary mechanisms to help explain this relation. Specifically, based on the neo-socioanalytical model of personality change, we hypothesized that those Big Five personality domains that change with age and trait negative affect would mediate this relation. These hypotheses were supported, as the Big Five traits conscientiousness, agreeableness, and neuroticism, as well as trait negative affect simultaneously mediated the negative relation between age and workplace deviance. These findings highlight two important underlying mechanisms for this relation and suggest several opportunities for organizations to reduce the occurrence of workplace deviance. Further theoretical and practical implications as well as limitations and future research ideas are discussed.

Introduction: The objective of this study was to investigate the effects of lead on concentration and motility of spermatozoa recovered from epididymis and testes in mature male offspring whose mothers were exposed to different doses and concentrations of lead acetate during gestation period. Materials and Methods: Seventy two healthy mature female mice were divided into three major groups according to the number of injections involving 1, 2 and 3 injections. Each major group was subdivided into four minor groups according to the concentration dose of (0, 25, 50 and 100) mg/Kg of lead acetate. Sperm concentration, percentage of motility and grade of activity were microscopically examined and statistically analyzed. Results: A significant reduction in the sperm functions were seen in relation to an increased in the number of injections and/or concentration of lead acetate dose as compared with the control groups. Conclusion: The toxic effects of lead acetate may interfere with spermatogenesis and metabolism of spermatozoa.
