Galaxy Properties from the Ultra-violet to the Far-Infrared: Lambda-CDM models confront observations

We combine a semi-analytic model of galaxy formation with simple analytic recipes describing the absorption and re-emission of starlight by dust in the interstellar medium of galaxies. We use the resulting models to predict galaxy counts and luminosity functions from the far-ultraviolet to the sub-mm, from redshift five to the present, and compare with an extensive compilation of observations. We find that in order to reproduce the rest-UV and optical luminosity functions at high redshift, we must assume an evolving normalization in the dust-to-metal ratio, implying that galaxies of a given bolometric luminosity (or metal column density) must be less extinguished than their local counterparts. In our best-fit model, we find remarkably good agreement with observations from rest-frame 1500 Angstroms to 250 microns. At longer wavelengths, most dramatically in the sub-mm, our models underpredict the number of bright galaxies by a large factor. The models reproduce the observed total IR luminosity function fairly well. We show the results of varying several ingredients of the models, including various aspects of the dust attenuation recipe, the dust emission templates, and the cosmology. We use our models to predict the integrated Extragalactic Background Light (EBL), and compare with an observationally-motivated EBL model and with other available observational constraints.
ICT Utilization in Indonesian Language Learning at the Junior High School Level in Buleleng Regency, Bali, Indonesia

The Covid-19 pandemic has made face-to-face learning unable to take place in class. Therefore, ICT from various platforms is the main choice that must be used, especially in Indonesian language learning for junior high schools. However, the efforts to improve the professionalism of Indonesian language teachers in utilizing ICT for online learning have not been carried out. This study aims to describe 1) the learning tools that utilize ICT, 2) the use of ICT in learning, and 3) the obstacles to the using of ICT in Indonesian language learning at the junior high school level in Buleleng Regency, Bali. This research method is descriptive qualitative. Data collection techniques were carried out using observation, interview, and documentation study techniques. The data were analyzed with the principle of TPACK used in learning. The results show that 1) learning tools that utilize ICT contain components that are integrated with internet technology, 2) ICT in Indonesian language learning at the junior high school level is used to deliver assignments, explain concepts, discuss, and evaluate learning, 3) the obstacles in utilizing ICT by Indonesian language teachers, among others, students lack enthusiasm for learning, poor internet network, and some students are not skilled yet in using applications/technology. Theoretically, this study has an implication to second language learning, especially on Indonesian language using TPACK principle, both in school and higher study level.
Regulation of the TUG1/miR-145-5p/SOX2 axis on the migratory and invasive capabilities of melanoma cells

Melanoma is the most prevalent malignancy of cutaneous carcinomas. Taurine-upregulated gene 1 (TUG1), a lncRNA, is a pivotal regulator of cutaneous malignancies. The present study aimed to investigate the impact and possible mechanisms of action of TUG1 behind the progression of melanomas. Reverse transcription-quantitative PCR was conducted to detect the expression levels of TUG1, microRNA (miR)-145-5p and SOX2 in melanoma tissues and cell lines. Cell Counting Kit-8 (CCK-8) assays were performed to measure the proliferative ability of melanoma cells and transwell assays were used to examine the migration and invasion of melanoma cells. Dual luciferase reporter and RNA immunoprecipitation (RIP) assays were utilized to identify the interactions among TUG1, miR-145-5p and SOX2. Western blotting and immunohistochemical assays were performed to determine the expression profile of SOX2. The impact of TUG1 on melanoma tumorigenesis was assessed using tumorigenicity assays. TUG1 expression levels were elevated in melanoma tumor tissues and cell lines. Reduced TUG1 expression levels significantly inhibited the proliferative, migratory and invasive abilities of melanoma cells. The expression levels of miR-145-5p were decreased in melanoma tumor tissues and cell lines. TUG1 directly targeted miR-145-5p and downregulated miR-145-5p. Upregulation of TUG1 counteracted the promotion of the proliferative, migratory and invasive abilities of melanoma cells induced by the overexpression of miR-145-5p. SOX2 was a target of miR-145-5p and its expression was negatively regulated by miR-145-5p, while positively regulated by TUG1. TUG1 regulated SOX2 expression through sponging miR-145-5p. Silencing of TUG1 also inhibited melanoma tumorigenesis in mice. In conclusion, the TUG1/miR-145-5p/SOX2 axis regulated the migration and invasion of melanoma cells.
Exploring the Molecular Interactions of Symmetrical and Unsymmetrical Selenoglycosides with Human Galectin-1 and Galectin-3

Galectins (Gals) are small cytosolic proteins that bind β-galactoside residues via their evolutionarily conserved carbohydrate recognition domain. Their dysregulation has been shown to be associated with many diseases. Consequently, targeting galectins for clinical applications has become increasingly relevant to develop tailored inhibitors selectively for one galectin. Accordingly, binding studies providing the molecular details of the interaction between galectin and inhibitor may be useful for the rational design of potent and selective antagonists. Gal-1 and Gal-3 are among the best-studied galectins, mainly for their roles in cancer progression; therefore, the molecular details of their interaction with inhibitors are demanded. This work gains more value by focusing on the interaction between Gal-1 and Gal-3 with the selenylated analogue of the Gal inhibitor thiodigalactose, characterized by a selenoglycoside bond (SeDG), and with unsymmetrical diglycosyl selenides (unsym(Se). Gal-1 and Gal-3 were produced heterologously and biophysically characterized. Interaction studies were performed by ITC, NMR spectroscopy, and MD simulation, and thermodynamic values were discussed and integrated with spectroscopic and computational results. The 3D complexes involving SeDG when interacting with Gal-1 and Gal-3 were depicted. Overall, the collected results will help identify hot spots for the design of new, better performing, and more specific Gal inhibitors.
PREVALENCE OF SEXUAL HARASSMENT AMONG WOMEN AGRICULTURAL LABORERS AND PERCEIVED IMPACTS ON THEIR PHYSICAL & MENTAL HEALTH

Large number of women is working as laborers in agricultural sector of Pakistan particularly in cotton picking, wheat harvesting, rice transplanting, and dairy sector. Gender based Violence and sexual harassment is fairly observable and reported in the formal sector of the urban areas but a research gap exists to study sexual harassment in informal sector, and particularly in agriculture sector. Present study is intended to understand the patterns and types of sexual harassment of woman laborers in agriculture sector. A sample of 250 women agricultural laborer/workers from five districts of Punjab province were selected for a face to face survey to explore the patterns of sexual harassment and its perceived impact for their health and the stigma attached to report such incidences. The views of male counterparts were obtained through key informant interviews of agricultural contractors and landlords. The results revealed that majority of the respondents faced gender based discrimination (50 %), low wages as compared to men (64 %), lack of respect (45.2 %) and negative attitudes of male workers (44 %). The data regarding verbal harassment indicated that such incidences are on the higher side (38.4 %) as compared to non-verbal (28.8 %) and physicaal (9.6 %) types of sexual harassment. The woman laborers also suffered different physical and psychological consequences of sexual harassment like; sleeping problem, depression, anxiety and isolation. However, the trend of not lodging the complaints by the victims was clearly evident i.e. 91.6 % representing the stigma and fear of disgrace associated with sexual harassment in the rural communities of Pakistan. Strong advocacy campaigns by academia and Non-governmental agencies to sensitize the rural communities are seriously required coupled with extending the purview of labor laws and harassment act of Pakistan to informal workers by policy makers.
Ease and Willingness to Use Smartphone Applications for Visual Acuity Assessment Among Patients in Ahmadu Bello University Teaching Hospital, Zaria

Background: Smartphone applications (apps) are increasingly becoming more popular for medical use. Aim: The aim of this article is to determine the willingness and ease of using smartphone apps for visual assessment among adult patients attending the general outpatient ophthalmology clinic of Ahmadu Bello University Teaching Hospital, Zaria in Nigeria. Design: The study was a hospital-based descriptive cross-sectional design. Materials and Methods: New and old adult patients who presented at the clinic and consented to the study were selected. Visual acuity assessment was done using a 6-m Snellen chart and three selected Smartphone visual acuity applications sequentially. A semi-structured questionnaire was used for data collection and then analysed using SPSS version 23. Results: A total of 287 patients were studied. Majority (96%) of the patients found the Smartphone apps to be easy to use. A good proportion (76%) of the patients also believed that Smartphone charts were easier to use than the conventional Snellen chart and expressed willingness to use the app again. Conclusion: Smartphone visual acuity apps could offer a convenient, easy-to-learn, and easy-to-use means of visual acuity assessment. This coupled with the demonstrated patient’s willingness to embrace this technology could be used to encourage the use of clinically validated apps for the early detection as well as monitoring of any impairment of vision, especially in out-of-clinic situations.
Exploring interfirm collaboration processes of small- and medium-sized enterprises: an institutional logics perspective

ABSTRACT This research examines the formation and development processes of interfirm collaboration among SMEs in the context of institutional logics change in an emerging economy. Building on the microfoundations lens and the institutional logics perspective, the empirical investigation focuses on the qualitative study of the interfirm collaborative relationships among SMEs in China. The research findings underscore the significant role played by government-supported broker firms in fostering the formation and development of interfirm collaboration among SMEs. In particular, these broker firms first reproduce the institutional logics by means of championing government-promoted projects and events and diffusing government policies through their sensemaking and sensegiving. The reproduction of institutional logics by broker firms facilitates the formation and development processes of interfirm collaboration among SMEs which, over time, may lead to collaboration success occurrences that are predominantly manifested by success events, artefacts and stories. In the case of new meanings emergent from the collaboration success occurrences, broker firms tend to engage in legitimating these new meanings to transform the institutional logics. Thereby, this research contributes to the theoretical advancement in the fields of inter-organizational collaborations among SMEs and institutional logics.
Spatial variability in evaluation experiments of corn genotypes in the state of Mato Grosso do Sul, Brazil

Analysis of variance (ANOVA) is the most used procedure for comparing means between different groups. However, in some cases, disregarding the assumptions of ANOVA can lead to spatial dependence. In such cases, to ensure greater experimental precision, it is necessary to consider the study of spatial dependence. This study was carried out to compare the estimates of experimental precision of the traditional analysis of variance with those of the analysis of variance using an autoregressive (ANOVA-AR) model in corn experiments under different N conditions when evaluating grain yield. Data were obtained from 14 experiments using lattice designs conducted in 2012, 2014, and 2015 in the following counties in the Brazilian state of Mato Grosso do Sul: Caarapó, Dourados, Glória de Dourados, and Laguna Carapã. Of the 14 experiments, 7 were performed with N fertilization (ideal) and 7 experiments were performed under stressful conditions (zero or low). Both analyses were compared by considering estimates of reduction of the error mean square, coefficient of determination, F-value, and selective accuracy as well as the difference in the order of 25% of the genotypes of each experiment (from 13 to 56 genotypes, considering the size of the experiment). Differences in the error mean square and genotype mean square were slightly more evident in 1, 2, 3, 4, 5, 6, and 11 experiments but the use of ANOVA-AR did not promote major changes. The analysis of variance with an autoregressive model provided parameter values of experimental precision similar to those expressed by traditional analysis of variance. There was no difference in terms of correlated errors in experiments under different N conditions.
International human rights teachers in Myanmar universities: The individual constraints of structure on intermediaries

Abstract The literature on the transnational promotion of human rights looks to the role of intermediaries who facilitate connections between global and local discourses. Local discourses, however, may host actors and dynamics with diverse perspectives not entirely receptive to international norms, and so call for attention as to how they impact the work of intermediaries. Myanmar university human rights teachers serve an intermediary role, receiving international human rights training from international aid programs and promoting such training within their professional work environments. The actors and dynamics of their work environments constitute local discourses affecting the conduct of university teachers, and thereby influence their efforts to promote international human rights norms. The analysis draws on empirical fieldwork involving the experiences of Myanmar university human rights teachers, using their concerns to demonstrate the ways their professional environments constrain their teaching of human rights. From such findings, the analysis raises implications for theories of intermediaries and international aid policies to promote human rights norms.
Stagnation, Creation, Breaking

This note deals with the mono-dimensional equation: $\d_t u -\d_x L(u_x) =f$ with $L(\cdot)$ merely monotone. The goal is to examine the features of facets -- flat regions of graphs of solutions appearing as $L(\cdot)$ suffers jumps. We concentrate on examples explaining strong stability, creation and even breaking of facets.
Dust production rate of asymptotic giant branch stars in the Magellanic Clouds

We compare theoretical dust yields for stars with mass 1 Msun 3 Msun and Z > 0.001. When compared to the most recent observations, our models support a stellar origin for the existing dust mass, if no significant destruction in the ISM occurs, with a contribution from AGB stars of 70% in the LMC and 15% in the SMC.
Preventive and Corrective Maintenance Practices on Instructional Technologies Adopted For Effective Instructional Delivery by Business Education Departments in Colleges of Education in Nigeria

The study was carried out to determine the preventive and corrective maintenance practices on instructional technologies adopted by Business Education Departments in Colleges of Education in Anambra and Enugu States of Nigeria. Two research questions and two null hypotheses guided the study. The population of the study was 165 lecturers and 10 laboratory attendants in Business Education Department. A 21-item-structured questionnaire was used for data collection. The questionnaire was validated and used to determine the reliability co-efficient of the instrument using Crombach Alpha approach, and 0.84 was obtained as the reliability coefficient. Mean and standard deviation were used to find answer to the research questions, while the hypotheses were tested using t-test statistic at the probability level of 0.05. The results of the analysis showed that the Business Education Departments adopted both the preventive and corrective maintenance practices. Based on the findings, it was recommended that the Departments should make deliberate efforts to strengthen the use of the preventive and the corrective maintenance practices. It was also recommended that qualified personnel should be employed to use and maintain the instructional technologies.
Online Teaching Competencies among Faculty Members at Modern College of Business and Science (MCBS) Sultanate of Oman

Online education has become an imperative not only due to the technological innovations but also due to the emerging social conditions arising out of COVID-19. Technological competencies are essential among the instructors for successful online teaching. Modern College of Business and Science (MCBS), Sultanate of Oman is one of the pioneering institutions in the Middle East region in adopting hundred percent online education with the onset of COVID-19. Main aim of this research is to evaluate the online teaching competencies of instructors at MCBS. Competencies identified through the benchmarking exercise and from literature, were divided into pedagogical and technical competencies, spread across three stages of online teaching: before, during and after an online teaching session. A self-administered questionnaire was circulated among 80 instructors selected through the systematic random sampling technique, out of which 53 valid responses were received and used in the data analysis. Descriptive statistics along with paired and independent sample t tests and ANOVA were conducted for evaluating the online teaching competencies of the instructors at MCBS. Linear regression analysis was conducted to evaluate the relationship between qualification or certification in online instructional methods (independent variable QC) and online teaching competency (dependent variable OTC). Findings indicated lower/less technical competencies than the pedagogical competencies. Stage-wise analysis revealed that the technical competencies are lower in Stage 1. A regression model that explained 43 percent of variation in dependent variable revealed that OTC is dependent on QC. Thus, it is recommended that the instructors need to be supported in acquiring qualification or certification in online instructional methods. While theoretical implications relate to innovation diffusion theory and theory of distance education, practical implications of this research relate to the ongoing hundred percent online instruction method. This study can be extended to evaluating the impact of personal factors on the online teaching competency and to the wider participants in the higher education sector.
Half-linear dynamic equations on time scales: IVP and oscillatory properties

In this paper we show how the basic results of oscillation theory of the Sturm--Liouville linear differential equation $$ (r(t)y')'+p(t)y=0 $$ can be extended to the half-linear dynamic equation $$ (r(t)\Phi(y^\Delta))^\Delta+p(t)\Phi(y^\sigma)=0 \tag{HL$^\Delta$E} $$ on an arbitrary time scale, where $\Phi(x)=|x|^{\alpha-1}\sgn x$ with $\alpha>1$. In particular, the generalization of the so called Roundabout theorem is proved for equation (HL$^\triangle$E), which provides powerful tools for the investigation of oscillatory properties of this equation, namely the Riccati technique and variational principle. As an application we present Sturmian theory, oscillation and nonoscillation criteria for (HL$^\Delta$E). The questions concerning the existence and uniqueness of a solution of initial value problem are also discussed.
