Authors: Modawe GadAllah
Published: July 2022

Background: Diabetes mellitus is a metabolic disease known by chronic hyperglycemia which results from defective insulin action and secretion. Various studies have documented liver disease as a major cause of mortality in patients with type 2 diabetes. It is well known that the liver plays an important role in the maintenance of normal glucose levels during fasting as well as in the postprandial period Aim: To evaluate the levels of liver markers in type 2 diabetes patients in Khartoum state.  Materials and Methods: The study was conducted in Alribat University hospital, Sudan during the period from January 2018 to April 2019. Hundred subjects were included in the study, fifty patients previously diagnosed with Type 2 diabetes and similar number of age- andgender-matchedhealthy control subjects. The design of the study was cross-sectional, with a retrospective historical review through apersonal interview of all subjects.Blood was collected in a heparinized tube at room temperature and centrifuged for 10 minutes at 3500rpm, Serum liver markers concentrations were estimated by an enzymatic method in a fully Automated Biochemistry Analyzer (Cobas 3546). The data were analyzed using SPSS version 20.Results: The majority of patients were > 55 years. serum level of AST in type 2 diabetic patients and control group respectively were (31.26±10.34, 20.35±6.48) p value= 0.00), serum levels of ALT in type 2diabetic patients and control group respectively were (33.74±6.48, 19.70±6.23) p value= 0.00, serum level of ALP in Type 2 Diabetes patients and control group respectively were (125.20±49.61, 87.90±24.35) p value= 0.00,Serum level of GGT in Type 2 Diabetes patients and control group respectively were (47.72±9.01, 43.48±8.63) p value= 0.026. The mean BMI in type 2 diabetic patients and the control group respectively were (26.36±5.94,19.19±2.67), p value= 0.00, the correlation between duration of disease and liver enzymes GGT,ALT,AST and ALP respectively were (0.47,0.34,0.57,0.93). The current study showed in significant correlation between serum (GGT and ALT) and BMI of patients among type 2 diabetic patients (p value= 0.83,0.863) but significant correlation between serum (AST, ALT) and BMI of patients ( p value= 0.002,0.032).Conclusion: In the present study, a significant increase in the level of liver enzymes, ALT, AST, GGT ALP was observed in type 2 diabetic patients when compared to the normal group. Hence, we found an association between the level of liver enzymes, ALT, AST, and GGT in type 2 diabetic patients. Thus, these liver enzymes can be used as biomarkers for the assessment of type 2 diabetes, and we found no association between the level of liver enzymes, ALT, AST, and GGT in type 2 diabetic patients and duration of disease.
Discovery of mysterious Pakistatyrus in Tibet (Coleoptera: Staphylinidae: Pselaphinae)
Authors: Yin Zi-Wei
Published: July 2022

The monotypic genus Pakistatyrus Hlaváč, 2006 of the tribe Tyrini (Staphylinidae: Pselaphinae) previously contained a single species described based on two museum specimens found in northern Pakistan. Here I describe P. inconspicuus sp. nov. from a high-altitude area of Tibet. This species differs from P. ater Hlaváč, 2006 in reddish-brown coloration of the body, simple male antennae and metatibiae, and a much broader median lobe of the aedeagus. Both known species are probably locally endemic and have limited dispersal abilities, suggested by their greatly reduced elytra and lack of functional wings. A record of a second species from Tibet, which is represented by a female, is given.

Authors:   The University of Haifa, Basis Najwa , Shochat Tamar
Published: July 2022

Review question / Objective: The aim of this systematic review is to investigate observational studies on the association between religion and sleep in the adult population. To this end, the proposed systematic review will address the following question: What is the role religion plays in shaping an individual's sleep health? Condition being studied: Sleep is a fundamental biological process increasingly recognized as a critical indicator of development and overall health. Generally, insufficient sleep is associated with depressed mood, daytime fatigue, poor daytime functioning and daytime sleepiness, increased risk of cancer, cardiovascular problems, diabetes, and the cause of the higher risk of mortality. Furthermore, changes in sleep architecture and quality have been related to cognitive deterioration, including dementia and Alzheimer's disease. Here we will identify the role of religion in elements of sleep health, to include sleep duration and sleep quality, and associated health outcomes in the adult population.

The measurement of aminotransferases levels has become part of the routine biochemical tests done in children regardless of their clinical symptoms. Aminotransferases (ALT, AST) are tissue necrosis markers which change in both hepatic and extra-hepatic conditions. The aim of this study was to establish the etiology and clinical signifi cance of the cytolysis syndrome without cholestasis in children hospitalized for various pediatric conditions. The study group consisted of 394 children (aged between 1.5 months and 16 years)with elevated values of ALT, AST. The investigation protocol applied included history, full physical examination, complete biological investigations, viral markers and liver ultrasounds. Depending on the aminotransferases values as compared to the normal value (NV), the patients were included in 3 study subgroups: 222 patients with slightly elevated transaminases values (< 2xNV) (subgroup I), 164 patients with ALT and AST values between 2-3xNV (subgroup II) and 8 patients with TGP, TGO values > 3 x NV (subgroup III). The ALT and AST values were determined monthly during the first 3 months, and then every 2 to 6 months. In all groups the etiology was dominated by acute bacterial (respiratory, urinary, digestive) and viral (Epstein Barr, Cytomegalovirus infection) conditions. Other causes of cytolysis syndrome were nutritional and metabolic diseases (obesity, mellitus diabetes, phenylketonuria, cystic fibrosis, congenital hypothyroidism). The etiology remained unclear in 20.31% of the cases, yet the transaminase values returned to normal after 6 months with diet and hepatoprotective therapy. Slightly elevated ALT and AST values do not require thorough investigations, as they usually return to normal within the first three months. On the other hand, mildly and severe increases, which persist after three months therapy require further investigation to determine the etiology (viral infections, autoimmune, nutritional and metabolic diseases).

Although relatively common in adult pathology, acute acalculous cholecystitis with gallbladder perforation is a rather infrequent entity in pediatric practice. In many cases, its unspecific clinical symptoms and the often inconclusive medical imagining results lead to the diagnosis of acute acalculous cholecystitis being set intraoperatively. Nevertheless, this condition should be considered when setting the differential diagnosis of a peritonitis syndrome in children.

Durerea viscerală are particularităţi faţă de cea somatică: receptorii viscerali au grade diferite de angajare funcţională, nivelul nocicepţiei diferă de la un organ la altul, aferenţele viscerale puţine sunt predominant nemielinizate şi au o divergenţă extensivă la nivelul sistemului nervos central; răspunsurile antrenează activări autonomice. Matricea durerii viscerale abdominale, funcţională la naştere, este suprasolicitată prin impulsuri mecanice, chimice, osmotice; suprapunerea infecţiilor, inflamaţiilor prin mediatorii eliberaţi creează condiţiile „sensibilizării“ periferice şi centrale şi ale dobândirii „memoriei durerii“; factori comportamentali şi emoţionali pot agrava hiperactivitatea matricei durerii viscerale. În acest context patogenetic se delimitează durerea nonorganică şi forma ei severă, hiperalgezia viscerală. Se adaugă particularităţi genetice care influenţează pragul de sensibilitate la durere. Având la bază modelele biopsihosociale ale tulburărilor funcţionale, criteriile Roma III au etichetat durerile abdominale funcţionale şi sindromul de intestin iritabil ca posibile diagnostice directe şi nu doar diagnostice de excludere. Durerea non-organică, asociată frecvent cu dureri abdominale recurente, este printre cele mai frecvente probleme medicale întâlnite în pediatrie. Majoritatea pacienţilor cu dureri uşoare au o evoluţie favorabilă în timp; un procent redus prezintă simptome grave şi uneori dizabilitante. Pediatrii se confruntă frecvent cu delimitarea diagnosticului de durere non-organică şi, uneori, cu eşecuri terapeutice. Autorii prezintă date epidemiologice, mecanismele fiziopatologice implicate, abordarea clinică şi opţiunile terapeutice cu privire la durerea nonorganică şi hiperalgezia viscerală la copii şi adolescenţi.

Determinarea valorilor transaminazelor face parte din protocolul de investigaţii biochimice de rutină care se efectuează la copil, indiferent de simptomatologia clinică. Transaminazele (TGP, TGO) sunt markeri ai leziunilor tisulare care se modifică atât în afecţiuni hepatice, cât şi extrahepatice. Scopul acestui studiu a fost de a stabili etiologia şi semnificaţia clinică a sindromului de citoliză hepatică fără colestază la copiii internaţi pentru diverse afecţiuni pediatrice. Lotul de studiu a cuprins 394 de copiii (cu vârsta cuprinsă între 1,5 luni şi 16 ani) la care au fost decelate valori crescute ale transaminazelor. Protocolul de investigaţii a cuprins anamneza, examenul fizic, investigaţiile biologice complete, markerii virali şi ecografia hepatică.În funcţie de valoarea transaminazelor faţă de valoarea normală (VN), pacienţii au fost incluşi în trei loturi de studiu: 222 pacienţi cu creşteri uşoare ale TGP, TGO (< 2xVN) (lotul I), 164 pacienţi cu TGP, TGO între 2-3xVN (lotul II) şi 8 pacienţi cu TGP, TGO > 3xVN (lotul III). Valoarea transaminazelor a fost determinată lunar în primele 3 luni, iar ulterior, la interval de 2 până la 6 luni din momentul identificării hepatocitolizei. În toate loturile etiologia sindromului de citoliză a fost dominate de afecţiunile acute bacteriene (respiratorii, urinare, digestive) şi virale (infecţia cu virus Epstein Barr, Cito megalovirus). Alte cauze ale sindromului de citoliză au fost bolile nutriţionale şi de metabolism (obezitatea, diabetul zaharat, fenilcetonuria, fibroza chistică, hipotiroidismul congenital). În 20,31% dintre cazuri etiologia nu a fost elucidată, dar valoarea transaminazelor la 6 luni s-a normalizat ca urmare a dietei şi hepatoprotectoarelor. Creşterile uşoare ale valorii TGP, TGO nu necesită învestigaţii laborioase, ele normalizându-se în primele trei luni. Creşterile medii şi severe, persistente după trei luni de tratament, impun continuarea investigaţiilor pentru stabilirea etiologiei (infecţii virale, boli autoimune, nutriţionale şi de metabolism).

Informed consent has become a major, but also mandatory component in medical praxis nowadays. A great number of forums and publications emphasize its ethical and psychological commands, the most adequate way to obtain it and especially its legal implications. In pediatrics, the implications of this procedure are complex, sometimes confusing or not well understood. Thus, in clinical consultations or simple medical acts, the consent could be seen as implicit; when we talk about maneuvers that lead to psychological or physical discomfort, invasive investigations, including endoscopy or therapeutic acts with possible risks or complications, informed consent from parents or legal tutors, respectively an intellectually, psychologically and socially evolved, educated child’s consent (acceptance) becomes mandatory. We must, however, clarify the nuances between consent and acceptance, not only from the semantic point of view, the proportion of either of the two terms in the final decision, the minor patient’s ability to discern at different age stages and finally the role and the importance of the doctor in such decision makings.

Published: July 2022

PFAPA is a chronic condition including recurrent fever episodes, aphthous stomatitis, pharyngitis and adenitis. The authors emphasize peculiarities regarding diagnosis, evolution and cytokinic profile for PFAPA patients. 22 patients with PFAPA were included in study. Patients that fulfilled diagnosis criteria were analyzed regarding symptoms onset age, period of time between episodes and between disease onset and diagnosis and also data about inflammatory status. Authors compared 2 groups: “PFAPA group” including 6 patients (between febrile episodes) and “Non-PFAPA group” including 4 healthy children. Both groups were analyzed regarding serum levels of inflammatory markers and cytokines in order to identify a biological sensitive marker for PFAPA evolution pattern. Data was statistically analyzed using “independent sample t test”. Results. Authors noticed a low suspicion index for PFAPA diagnosis (underdiagnosed disorder) and significant statistical differences between the 2 groups regarding C reactive protein (CRP) serum value. Conclusions. PFAPA diagnosis is established lately, so it’s useful to disseminate information about disease. CRP remains a sensitive marker for disease activity in PFAPA patients, even out of fever attacks.

Covid-19 has spread to all countries in the world, including Indonesia. This spread affects all sectors, one of which is education. The impact that occurs in the education sector requires that every learning activity be carried out at home boldly. This change in learning patterns is thought to create stress on students, so good emotions are needed. The purpose of this study was to determine the relationship between emotions and the stress of learning to be brave in high school students in Sukoharjo. The subjects involved in this study were Sukoharjo High School students, totaling 268 students. The measuring instrument used is the maturity scale of Singh's theory (1990) and to measure stress the Depression Anxiety Stress Scales (DASS) is one of the commonly used measuring tools. Results Based on the analysis, the sign value was obtained. = 0.00, which means that there is a significant relationship between emotional maturity and stress (sign < 0.05). In the analysis of the r value, the value of t count > from t table (-0.552 > 0.148) at a significance level of 1%, it can be interpreted that emotional maturity has a strong enough relationship with stress. The relationship between these two variables is negative, that is, increasing the emotional value, the lower the stress value.
Pathlike Co/Bialgebras and their Antipodes with Applications to Bi- and Hopf Algebras Appearing in Topology, Number Theory and Physics
Authors:   Purdue University, USA, Kaufmann Ralph M. , Mo Yang ,   Purdue University, USA
Published: July 2022

We develop an algebraic theory of colored, semigrouplike-flavored and pathlike co-, bi- and Hopf algebras. This is the right framework in which to discuss antipodes for bialgebras naturally appearing in combinatorics, topology, number theory and physics. In particular, we can precisely give conditions for the invertibility of characters that is needed for renormalization in the formulation of Connes and Kreimer. These are met in the relevant examples. In order to construct antipodes, we discuss formal localization constructions and quantum deformations. These allow to define and explain the appearance of Brown style coactions. Using previous results, we can interpret all the relevant coalgebras as stemming from a categorical construction, tie the bialgebra structures to Feynman categories, and apply the developed theory in this setting.

Published: July 2022

An extensive exploration of the model parameter space of axisymmetric early type galaxies (ETGs) hosting a central supermassive black hole (SMBH) is conducted by means of high-resolution hydrodynamical simulations performed with our code MACER. Global properties such as (1) total SMBH accreted mass, (2) final X-ray luminosity and temperature of the X-ray emitting halos, (3) total amount of new stars formed from the cooling gas, and (4) total ejected mass in the form of supernovae and active galactic nuclei (AGN) feedback induced galactic winds, are obtained as a function of galaxy structure and internal dynamics. In addition to the galactic dark matter halo, the model galaxies are also embedded in a group/cluster dark matter halo; finally, cosmological accretion is also included, with the amount and time dependence derived from cosmological simulations. Angular momentum conservation leads to the formation of cold H i disks; these disks further evolve under the action of star formation induced by disk instabilities, of the associated mass discharge onto the central SMBH, and of the consequent AGN feedback. At the end of the simulations, the hot (metal-enriched) gas mass is roughly 10% the mass in the old stars, with twice as much having been ejected into the intergalactic medium. The cold gas disks are approximately kiloparsec in size, and the metal-rich new stars are in 0.1 kpc disks. The masses of cold gas and new stars are roughly 0.1% of the mass of the old stars. Overall, the final systems appear to reproduce quite successfully the main global properties of real ETGs.
Thermocline Depth on Water-rich Exoplanets
Authors: Lai Yanhong , Yang Jun
Published: July 2022

Water-rich exoplanets are a type of terrestrial planet that is water-rich and whose ocean depth can reach tens to hundreds of kilometers with no exposed continents. Due to the lack of exposed continents, neither western boundary current nor coastal upwelling exists, and ocean overturning circulation becomes the most important way to return the nutrients deposited in the deep ocean back to the thermocline and to the surface ocean. Here we investigate the depth of the thermocline in both wind-dominated and mixing-dominated systems on water-rich exoplanets using the global ocean model MITgcm. We find that the wind-driven circulation is dominated by overturning cells through Ekman pumping and subduction and by zonal (west–east) circum-longitudinal currents, similar to the Antarctic Circumpolar Current on Earth. The wind-influenced thermocline depth shows little dependence on the ocean depth, and under a large range of parameters, the thermocline is restricted within the upper layers of the ocean. The mixing-influenced thermocline is limited within the upper 10 km of the ocean and cannot reach the bottom of the ocean even under extremely strong vertical mixing. The scaling theories for the thermocline depth on Earth are applicable for the thermocline depth on water-rich exoplanets. However, due to the lack of exposed continents, the zonal and meridional flow speeds are not in the same magnitude as that in the oceans of Earth, which results in scaling relationships for water-rich exoplanets being a little different from that used on Earth.
Probing Population III Initial Mass Functions with He ii/Hα Intensity Mapping

Published: July 2022

We demonstrate the potential of line-intensity mapping to place constraints on the initial mass function (IMF) of Population III stars via measurements of the mean He ii 1640 Å/Hα line-intensity ratio. We extend the 21cmFAST code with modern high-redshift galaxy-formation and photoionization models, and estimate the line emission from Population II and Population III galaxies at redshifts 5 ≤ z ≤ 20. In our models, mean ratio values of He ii/H α ≳ 0.1 indicate top-heavy Population III IMFs with stars of several hundred solar masses, reached at z ≳ 10 when Population III stars dominate star formation. A next-generation space mission with capabilities moderately superior to those of CDIM will be able to probe this scenario by measuring the He ii and Hα fluctuation power spectrum signals and their cross-correlation at high significance up to z ∼ 20. Moreover, regardless of the IMF, a ratio value of He ii/Hα ≲ 0.01 indicates low Population III star formation and, therefore, it signals the end of the period dominated by this stellar population. However, a detection of the corresponding He ii power spectrum may be only possible for top-heavy Population III IMFs or through cross-correlation with the stronger Hα signal. Finally, ratio values of 0.01 ≲ He ii/Hα ≲ 0.1 are complex to interpret because they can be driven by several competing effects. We discuss how various measurements at different redshifts and the combination of the line-intensity ratio with other probes can assist in constraining the Population III IMF in this case.

We present sensitive NH3 (1,1)–(7,7) line images from the Karl G. Jansky Very Large Array toward successive shocks, which are associated with the blueshifted outflow lobe driven by the compact protobinary system L1157. Within a projection distance of 0.1 pc, our observations not only trace the quiescent and cold gas in the flattened envelope, but also illustrate the complex physical and chemical processes that take place where the high-velocity jet impinges on its surrounding medium. Specifically, the NH3 ortho-to-para ratio is enhanced by a factor of 2–2.5 along the jet path, where the velocity offset between the line peak and the blueshifted wing reaches values as high as 10 km s−1; it also shows a strong spatial correlation with the NH3 column density, which is enhanced to >1016 cm−2 toward the shock cavities. At a linear resolution of 1500 au, our refined temperature map from the seven NH3 lines shows a gradient from the warm B0 eastern cavity wall (>120 K) to the cool cavity B1 and the earlier shock B2 (<80 K), indicating shock heating.

Authors: Hidayanti Lilik , Rahfiludin M. Zen , Nugraheni Sri Achadi , Murwani Retno
Published: July 2022

Background: Worldwide, More than 340 million children and adolescents have overweight problems, and snacking habits are likely contributing factors. However, little is known about habitual snack consumption in school, especially regarding snack types that may lead to overweight. 
Purpose: Our study aims to analyse the association between habitual snack consumption and the prevalence of overweight in junior high school students.
Methods: An observational study with a cross-sectional design was conducted in Tasikmalaya, West Java, Indonesia, involving 397 participants from five public junior high schools. The habitual snack consumption included the consumption habits of various types of snacks (sweet-fried snacks, salty-fried snacks, sweet-non-fried snacks, salty-non-fried snacks, fruits, and sugar-sweetened beverages) measured by a food frequency questionnaire (FFQ) and categorised into rarely and often. The overweight status was determined based on the BMI-for-age z-score (BAZ) and categorised into not-overweight and overweight. We analysed the data using a logistic regression test. 
Results: The habits of often consuming sweet-fried snacks (p<0.001; aOR=5.448; 95% CI=2.303–12.886), salty-fried snacks (p=0.040; aOR=3.662; 95%CI=1.063-12.621), and sugar-sweetened beverages (p=0.026; aOR= 3.100; 95%CI=1.143-8.407) were risk factors associated with overweight.
Conclusion: The habit of often consuming sweet-fried snacks was a risk factor for being overweight with the greatest odds. Therefore, education on healthy snacks could be included in school learning materials to prevent overweight in adolescent students.

Mejicanotrichia Harris & Holzenthal, 1997 is a small genus of Hydroptilidae (Trichoptera), which consists of seven species, six of them distributed in Mexico, and one more in Guatemala. Larval descriptions of only two species (M. blantoni and M. estaquillosa) were previously known, as well as only females of three species (M. blantoni, M. estaquillosa, and M. tamaza) previously described. The present study provides descriptions of the larvae of M. harrisi and M. tridentata, as well as a description of the female of M. harrisi. Identification keys for adult males, known females, and known larvae are also provided. This work aims to incorporate more information into the taxonomy of the genus, its ecology, and facilitate additional characters of potential use in future phylogenetic studies.

Authors: Johan Arief Prima , Yusuf Anom
Published: July 2022

Purpose: This study aims at comprehending counterproductive behavior from negative workplace situations, namely job stress. As job stress is an individual attitude, trait emotional intelligence (EI) was considered the determinant factor. In addition, the effect of person-organization (PO) fit was also scrutinized as a predictor of job stress.Design/methodology/approach: The study used quantitative surveys in the leasing industry of Indonesia. 88 valid responses were used in the analysis. The analysis was conducted using Structural Equation Modelling with the help of the Smart PLS. The variables were measured using robust indicators from previous studies.Findings: The results confirmed three meaningful relationships between counterproductive work behavior, job stress, trait EI and PO fit. Specifically, the analysis found a negative association between trait EI and job stress. It also revealed the negative effect of PO fit on job stress. However, the study failed to provide empirical evidence to support the relationship between job stress and counterproductive work behavior.Research Limitations: This study has low generalization power since it did not construct from large sample size. Future research efforts should consider adding alternative dimensions that could help to better understand and predict CWB.Practical and Social Implications: This study provides guidelines for practitioner to select and promote high EI candidates since they are proven to be less susceptible to stress. This study also suggests companies to align working atmosphere with employees’ characteristics. It also contributes to social interaction in the workplace by pointing companies to establish less stressfully work atmosphere.Originality/value: This study considers alternative procedures to measuring counterproductive work behavior compared to those used in previous studies. Additionally, this study includes both personal or individual characteristics and interaction between the person and the organization to predict job stress.

Authors: Smadja David , Mimouni Michael , Shoshani Avi , Kaiserman Igor , Lavy Itay , Santhiago Marcony R.
Published: July 2022

PURPOSE:

To determine the reliability of the percentage of tissue altered (PTA) calculation as part of the planning strategy for myopic laser in situ keratomileusis (LASIK) by comparing the estimated PTA provided by preoperative calculation to the postoperative PTA actually achieved in microkeratome-assisted myopic LASIK.

METHODS:

This retrospective study included 3,624 eyes of 3,624 patients who underwent mechanical microkeratome-assisted LASIK surgery for myopic correction. The calculated preoperative PTA values based on the planned flap thickness and ablation depth were compared with the actual achieved postoperative PTA using the difference of corneal central thickness postoperatively for assessing the achieved ablation depth and the intraoperative ultrasound-assisted flap thickness measurement. Regression analysis was performed to reveal preoperative parameters that might influence PTA calculation accuracy.

RESULTS:

The mean difference between the estimated and achieved PTA was 0.451 ± 3.45% (
P
< .001) (95% CI: 0.3708 to 0.5322) with a preoperative and postoperative mean PTA of 31.07 ± 4.07% and 31.52 ± 5.78%, respectively. The differences between the achieved and planned maximum ablation depth and flap thickness were 4.32 ± 13.70 µm (
P
< .001) and −1.61 ± 13.66 µm (
P
< .001), respectively.

CONCLUSIONS:

Although a statistically significant difference was found between the preoperative calculated PTA and actually achieved PTA, the difference in PTA value (less than 1%) was clinically non-significant and indicated a highly reliable metric for preoperative refractive surgery planning.

El comparatismo de María Rosa Lida
Authors: Bono Velilla Rosa
Published: July 2022

La labor crítica de María Rosa Lida demuestra un carácter esencialmente integrador e imparcial que permite considerar, desde una perspectiva histórica, la trascendencia de su contribución al comparatismo en dos de los debates más importantes en torno a los que ha gravitado la disciplina: la dialéctica entre tradición y originalidad y la continuidad de la cultura europea. La figura intelectual de María Rosa Lida se presenta como un caso de especial relevancia para la escritura de una historia de la literatura europea capaz de comprender otros ámbitos, como la filología, otros géneros textuales, como el de los artículos-reseña que dedicó a Curtius y Highet, y voces ajenas en otros tiempos, como la judía y la islámica en la literatura occidental de la Edad Media y el Renacimiento.
«¿Cuál es la edad mejor para el poeta?»: discursos sobre la edad en tiempos de Cervantes y Lope de Vega
Authors: Castillo Bejarano Rafael
Published: July 2022

Los escritores y poetas del seiscientos instrumentalizaron los discursos sobre la edad, retomados de la antigüedad por los humanistas en la modernidad temprana, reelaborando a su conveniencia las doctrinas sobre el ingenio natural, el valor de la experiencia o la constitución humoral, para proponer una figura del autor ideal que privilegiara sus propias carreras literarias. Este artículo analiza los discursos confrontados y cambiantes sobre la edad en Cervantes, Lope de Vega y sus contemporáneos como estrategias para reclamar la centralidad en el campo literario según un disputado concepto sobre el autor genuino.

Published: July 2022

The countrywide lockdown since March 2020 due to COVID 19 pandemic has brought drastic changes in the Indian education system. Today, many higher education institutions offer online delivery as an alternative and/or addition to provide more flexibility to learners, specifically in the current COVID 19 Pandemic. The conventional teaching method to the technology-driven virtual mode of teaching provided opportunities with challenges to academic stakeholders. Now with the new session, discussions on the reopening of educational institutions are going on. Hence, it is time to review the learning that took place during this pandemic situation. Learners being confronted with such services come with different expectations of what that means to their learning paths and behaviors. Learning Analytics is a relatively new and innovative way of making learner behavior and performances explicit by analyzing significant learners' feedback data. In this study, we take the case of online courses offered by various educational institutions all over India, and the analysis encompasses the population of learners of the online courses during the COVID 19 Pandemic period. Primary data has been collected using Google form when journals, reports, and websites are secondary data collection sources. We classified the data into distinctive parts: the overall learning experience of this course, the fulfillment of the learners' objectives, the difficulty of the assignments, the quality of the material supplied, the difficulty level of the course, the quality of the live session, opinion about the virtual approach of teaching, opinion about the contribution of virtual academic programs on knowledge building, opinion about the impact of virtual mode of teaching on performance, and opinion about the causes affecting students’ performance in the virtual mode of learning. The analysis outcomes will guide the host institutions and other similar institutions to design their pedagogy for future online courses more effectively, influencing learner engagement and retention.

Published: July 2022

The negative phenomena in the society have subtle influences on the values of college students. Studying the interaction mechanism for the entrepreneurship of college students in the new era will help them establish a healthy entrepreneurial mentality. The current research focuses mainly on the development connotation and mode of the interaction mechanism for the entrepreneurship of college students, which is highly subjective and lacks empirical quantitative analysis of the interactions between multiple participants in the interaction mechanism for entrepreneurship. This paper studies the interaction mechanism for entrepreneurship of college students with diversified values. First an asymmetric game payoff matrix was established for the multiple participants including colleges, college students and cooperative enterprises in the interaction mechanism for entrepreneurship of college students, and then a replicator dynamic equation for the evolutionary game of multiple participants was solved, so as to objectively analyze the optimal behavior decisions of the multiple participants under the condition of bounded rationality. The experimental results verified the effectiveness of the constructed model.

Published: July 2022

Vocational education graduates should have expertise competencies according to their fields so that it is easy to fill the job market, but this condition is not in line with expectations. BPS data as of February 2020 still shows the open unemployment rate, which is dominated by SMK graduates, at 8.49%, meaning that it is the highest-ranking contributor to open unemployment. One indication of this high percentage is the lack of work skills for vocational school graduates in the world of work. This lack of work competence is indicated because the learning process is not integrated with the real world of work. Therefore, improvement steps are sought through a learning process that integrates school learning with the real world of work by developing media that support learning activities with the real world of work. Therefore, the purpose of this research is to design an Android-based interactive lean manufacturing application to improve the work skills of vocational students. This study uses the 4D development method (four-Ds) for the development of android-based interactive lean manufacturing applications and uses a survey method for validity and this AR application will be validated by 3 experts. The results of this study indicate that the validation test of android-based interactive lean manufacturing applications is included in the valid category. So, it can be concluded that the Android-based interactive lean manufacturing application technology has been valid to be used in the learning process.

Published: July 2022

This research paper emphasizes the relationship between certain variables that influence the consumer's intention to use Self-Service Technologies (SST) in the retail sector. With the rapid growth of technology, various technological.

innovations are being introduced to make it easier for people to satisfy their needs and wants. One of the technologies that are very popular among customers is self-service checkout. However, previous studies on investigating the SST mainly focus on the technology adoption perspective and only a few studies have attempted to report from the consumer behavior perspective. As such, this paper aims to investigate the relationship between the customer’s traits (technology anxiety, need for interaction, technology innovativeness, and demographics) towards the consumer intention to use SST. Two hundred answers were collected randomly among the Tesco customer in Malaysia. The data were then analyzed using SmartPls version 3   to validate the developed hypothesis which forms the foundation for the research model. The finding revealed that only technology anxiety, technology innovativeness, and demographics affect the consumer intention to use SST. The findings are important to the retailer to continue improving the current system in addressing 1. potential user(demographic), system complexity and safety (technology anxiety), and system features-interactive system (technology innovativeness) to give a different experience to the user as compared to traditional practice.
