Physiological action of vitamin D3 in health and disease
Authors: Mohammad Joda AL-Hadrawy Suaad 
Published: March 2023

Vitamin D is the common molecules for every steroid that has the biological effects of cholecalciferol. Vitamin D can be synthesized in the mammalian skin after exposed to ultraviolet (UV) waves and this process occur endogenously. Amongst diverse Vitamins, VitD has powerful effects on the immune system. As major components of the diet, vitamins have essential effects on the innate and acquired immune system. The active form of VitD is calcitriol (1,25(OH)2VitD3). Calcitriol (1,25(OH)2VitD3) is the active form of VitD. Calcitriol regulates antimicrobial peptides productions, comprising defensin and cathelicidin, that controller the natural intestine microbiota floor and supports intestinal barriers. VitD in controlling the immune response in infectious and autoimmune diseases. There is a theory that VitD complements could be beneficial for treatment of COVID-19. Vit D has an important anti-inflammatory function on the immune system by reducing the production of pro-inflammatory cytokines and increasing anti-inflammatory cytokines in immune cells. Also, vitamin D deficiency is closely related to chronic diseases such as osteoporosis, type 1 and type 2 diabetes, hypertension, cardiovascular disease and cancer. In addition, recently it was revealed that vitamin D receptors (VDR) are expressed in many organs such as the testes, and vitamin D may be a adjustable regulator of reproductive function and fertility.

CHARACTERISATION OF FOOD GUILDS OF THE CLASS GASTROPODA ON THE NORTHEAST ROCKY COAST OF THE GULF OF CALIFORNIA
Authors: Arvizu Ruiz Adrian , Reyes Bonilla Hector 
Published: March 2023

Few detailed studies are available on class Gastropoda ecology in rocky intertidal areas of the Gulf of California, and none have been conducted in significant latitudinal scale for the region in the last 30 years. This study outlines food guilds of the macrogastropod community (≥1 cm) found in the rocky intertidal zone of 13 coastal sites of the northeast Gulf of California (latitudes 27° N - 31° N) through visual census in transects of 40 m perpendicular to the coast with 2 m2 quadrants every 20 m. The results gathered a total of 5823 records of 41 species. The classification for food type included five guilds, of which algivores stood out with the highest (50.87%) abundance; carnivorous predators represented 19.22% of species abundance; carnivores 14.19%, omnivores 14.51% and microalgivores less than 2% of the total. In the intertidal zone algivore abundance significantly decreased at the lowest level while carnivores were well represented in middle and lower levels. Food guild latitudinal distribution was heterogenous without a specific latitudinal pattern, but trophic diversity tended to be higher in sites on latitudes 29° N - 30° N. Non-metric multidimensional scaling demonstrated four principal areas that grouped algivores, predatory carnivores, omnivores, and carnivores (stress = 0.1). This study shows for the first time the diversity of trophic macro-mollusc guilds northeast of the Gulf of California, which highlights the importance and necessity of generating a solid base for detailed class research in the region.
¿Voto programático o evangélico? El apoyo electoral a la derecha radical en Brasil y Costa Rica
Authors: Sendra Mariana 
Published: March 2023

Este artículo se pregunta hasta qué punto el apoyo electoral de los evangélicos a los candidatos de derecha radical está impulsado por preferencias de políticas, considerando tres dimensiones: socioeconómica, sociocultural y autoritaria. Se enfoca en los casos de Brasil y Costa Rica, dos países que comparten un mismo resultado político: la emergencia de dos candidatos de derecha radical (Bolsonaro y F. Alvarado) con alto éxito electoral, explicado, en parte, por un factor común: el apoyo de las iglesias evangélicas pentecostales. Utilizando datos de LAPOP 2018-19, testeamos el efecto de las policy-preferences dimensions como hipótesis alternativa al voto confesional y, además, analizamos si existe un efecto de refuerzo ejercido por las preferencias sobre la confesión religiosa. Encontramos que solo en Brasil los evangélicos más conservadores votaron en mayor medida por Bolsonaro, mientras que, en Costa Rica, los evangélicos apoyaron a F. Alvarado independientemente de su posicionamiento en la dimensión sociocultural.
Les plus anciennes gravures rupestres du Sahara central ?
Authors: Striedter Karl Heinz , Tauveron Michel 
Published: March 2023

Dans les années 1960, F. Mori découvrit dans la Tadrart Acacus (Sud-Ouest libyen) un petit nombre de gravures rupestres qui ne pouvait être classé dans aucune famille connue de gravures, et qu’il qualifia d’« ichthyomorphes ». Au cours de recherches de terrain dans les années 1990 dans la Tadrart algérienne (prolongement de la Tadrart Acacus vers le sud), il a été retrouvé un nombre important de nouvelles gravures rupestres proches des « ichthyomorphes » de Mori et il semble désormais justifié de parler d’un faciès particulier de gravures rupestres du Sahara central. Ainsi que le montrent des superpositions, ces gravures précèdent les peintures de la période des « Têtes Rondes », et les observations géomorphologiques suggèrent de les dater vers la fin du Pléistocène.
TEST COMPLETION TIME, SUBJECT SCORES AND ACADEMIC SELF-EFFICACY. HOW DO THEY RELATE?
Authors: Kihoro Muya Francis 
Published: March 2023

<p>Educators always endeavor to unravel the myriad of unexplained variables in learning environments. Examination taking is one such variable. Given the importance attached to examination results, educators seek answers as to why some students have shorter completion time than others and whether they end up scoring better than those who finish later. Is this phenomenon related to their levels of academic self-efficacy? This study set out to investigate the relationship between academic behavior confidence, test scores and test completion time. It was grounded on the self-efficacy theory by Albert Bandura. In an exam-taking situation, twenty-five early finishers and twenty-five late finishers were identified in a common unit examination in a public university in Kenya. They later filled out the Academic Behavior Confidence scale developed by Sander &amp; Sanders (2019). The relationships between the completion time, the test scores on the common unit and their Academic Behavior Confidence scores were investigated using non-parametric approaches, specifically the Spearman’s rho and Mann-Whitney U test. Results show a significant difference between completion time and test scores. Paradoxically, there is no significant difference between completion time and ABC scores. However, there is a positive relationship between test scores and Academic Behavior Confidence scores. It is recommended that educators should use mastery experiences, verbal persuasion and vicarious experiences to enhance Academic Self-efficacy, which may, in turn, improve test scores.</p>.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0028/a.php" alt="Hit counter" /></p>
INVESTIGATION OF STUDENTS’ ATTITUDES TOWARD MATHEMATICS IN MIDDLE SCHOOLS IN SAUDI ARABIA
Authors: Alharthi Majed Saeed 
Published: March 2023

<p>Many students in Saudi Arabia complain that they achieve poor results in mathematics and appear to have a negative attitude toward the subject. The current study, therefore, investigates students’ attitudes towards mathematics, using a mixed method approach, in 13-16 years old students from the intermediate level of education. The age was important because this period is thought to be crucial to the formation of lasting attitudes and opinions. The first main research question, the study aims to address is therefore, “What are students’ attitudes towards mathematics in Saudi middle schools?” The study also aims to explore gender issues using a second research question, “Is there any significant gender difference in students’ attitudes towards mathematics?” The survey was conducted in two government-run middle schools in Saudi Arabia, one boys’ school and one girls’ school, because Saudi Arabia has an exclusively single-sex education system. 180 participants (90 boys and 90 girls) were asked to complete a questionnaire to show their views about mathematics. Qualitative and quantitative data were collected at the same time, but the analysis of each type of information was conducted separately to enable the full picture to be understood. T-test was used to explore any gender differences. The main findings were that both male and female students in two Saudi middle schools show a positive attitude towards mathematics, with female students being slightly more positive than males. The factors which affect attitudes towards mathematics in both genders include the usefulness of mathematics in everyday and future life and career, the teacher, enjoyment of mathematics and the difficulty of the subjects. Girls’ attitudes towards mathematics were also affected by the influence of social media personalities and internet teachers. </p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0050/a.php" alt="Hit counter" /></p>
