Predicting Academic Procrastination in Students: Perfectionism, general self-efficacy, and sociodemographic factors academic students:

Procrastination is frequently found in around 30% to 60% of college students. Research that examines academic procrastination isassociated with adaptive-maladaptive perfectionism, general self-efficacy, and sociodemographic factors, expected to gain a comprehensive understanding of procrastination so that anticipatory and countermeasures can be implemented. The target population of this study was male and female college students from state and private universities. The questionnaire was distributed physically and digitally (google-form) to 208 participants using the snowball sampling technique. The research instrument consisted of the Academic Procrastination Scale (APS), The Frost Multidimensional Perfectionism Scale (FMPS), General Self-Efficacy (GSE), and questions on sociodemographic factors. All research instruments have been tested and met the criteria of validity and reliability. After the data cleaning and coding process, the data were assessed using multiple regressions dan hierarchical regression. The data analysis revealed that perfectionism and self-efficacy were generally predictors of procrastination. Similarly, from the results of model testing, all sociodemographic factors simultaneously affected procrastination, but gender was in line with influencing procrastination. Research findings show that procrastination was more motivated by many anxieties due to excessive attention to mistakes and doubts in acting. This research has limitations, namely the origin of the participating universities, primarily private universities rather than state universities. As a result, the level of variability of data sources tends to be low. However, this study'sresults can be followed up to address the issue of academic procrastination.
Open Research Online

This investigation concerns two questions: i). is simple educational programming with children, compared to working on mathematical tasks, more effective in increasing scores in mathematical abilities, spatial awareness and working memory? ii), is educational programming on a digital device, compared to similar paper and pencil programming activities, more effective in increasing mathematical abilities, spatial awareness and working memory? Forty-one 5 to 6 year olds from a UK infant school were randomly allocated to one of three groups: programming+iPad technology, programming using paper and pencils, and a comparison condition involving pencil and paper mathematical addition and subtraction tasks. Two 10-min intervention sessions took place each week, over a period of six weeks, with pre-intervention and post-intervention tests administered to assess children ’ s mathematical abilities, spatial awareness and working memory. A series of mixed analyses of variance revealed that all three groups increased their mathematical abilities and spatial awareness. However, there were no significant increases in working memory, and there were no significant differences between any of the groups. These findings suggest that even a relatively short period of experience with programming can benefit other abilities and that the effects are similar to more directly targeted interventions. It was not found that programming using iPads resulted in higher scores than programming with paper and pencils.
Open Research Online The evolution of ancient ﬂuvial systems in Memnonia Sucli, Mars: impact crater damming, aggradation, and a large water body on the dichotomy?

There is conflicting evidence for an ancient ocean which occupied the northern hemispheric basin on Mars. Along different regions of the dichotomy boundary, sediment fans have been interpreted as either forming into a large water body or a series of smaller paleolake basins. Here, we investigate fluvial systems in the Memnonia Sulci region of Mars, set along the dichotomy, which comprise erosional valley networks, paleolake basins, inverted channel systems, and sediment fans. We focus our analysis on the evolution of the upslope catchment and characterizing the ancient environment of a large, downslope basin, bound by the topographic dichotomy and the Medusae Fosse Formation. The catchment fluvial systems comprise highly degraded valley networks and show a complex history of incision and filling, influenced by paleolake basin overflow, impact crater damming, aggradation, and possibly a downstream water body. The morphology of the sediment fans is consistent with either fluvial fans or deltas and they form at discrete elevations, rather than a common elevation plane. Our analysis is consistent with the sediment fans forming into a series of paleolake basins set along the dichotomy, rather than into a large inner sea or ocean-sized water body. The fluvial systems were likely active between the mid Noachian and early Hesperian periods. Our results demonstrate the complex, multi-phase evolution of fluvial systems on ancient Mars and highlight the importance of regional and local studies when characterizing ancient regions of the dichotomy. Mars's that fluvial activity likely occurred between the mid Noachian and early Hesperian. Our results (a) demonstrate the complex, multi-phase evolution of fluvial systems on ancient Mars (e.g., Edgett et al., 2020) and (b) highlight the importance of regional studies when assessing the nature of the northern lowlands basin on early Mars, which can differ from the global picture.
The Relationship Between Racial Microaggressions, Mental Health, and Academic Self- Efficacy in Black College Students : Is a Supportive Mentor Protective?

Racial microaggressions are daily, often subtle, verbal, environmental, and behavioral slights and insults targeted at a person or their race. Racial microaggressions can have deleterious effects on the mental health and academic outcomes of Black college students. As research on this relationship increases, it is essential to assess factors that may moderate, or lessen, the impact of racial microaggressions. There is evidence that mentoring, a form of social support, may attune the adverse effects of racial microaggressions on mental health and academic outcomes. The current study explored the relationship between racial microaggressions and mental health and academic outcomes (social anxiety, generalized anxiety, depression, and academic self-efficacy) in Black undergraduate students and assessed if the presence of mentoring moderated this relationship. Results suggest that racial microaggressions have a significant negative impact on mental health outcomes and none on academic self-efficacy. Additionally, while mentoring has a significant positive impact on three outcome variables, it does not operate as a buffer variable for the relationship between racial microaggressions and the study outcomes. As there is a direct relationship but not a buffering one, other factors may better attune the relationship between racial microaggressions and mental health and academic outcomes in Black college students. It also suggests that having a mentor can benefit college students’ mental health and well-being and can be used to offer support to the growing literature on the impact of social support in this population. Further research is needed to examine the potential buffers of the relationship. Given the beneficial impact of mentoring, additional research can further explore the longitudinal effects of mentoring on this population.
Impact of Confinement by COVID-19 in Awake and Sleep Bruxism Reported by Portuguese Dental Students

Confinement by COVID-19 was a stressful period that could potentially trigger awake bruxism (AB) and/or sleep bruxism (SB) behaviors. This study aims to characterize the AB and SB behaviors reported by Portuguese dental students before the pandemic and during the first period of mandatory confinement by COVID-19. Dental students were included in this longitudinal study. They answered the Portuguese validated version of the Oral Behavior Checklist (OBC) before the COVID-19 pandemic emerged (T1) and one month after mandatory confinement started in Portugal (T2). Descriptive statistics and the linear-by-linear association test were performed to assess changes over time (p ≤ 0.05). Sixty-four dental students (mean age 22.5 ± 2.8 years; 81.5% females) completed the study protocol. Considering AB, there was a general increase of the behavior from T1 to T2. The percentage of participants who reported to “grind their teeth when waking up” just few times decreased (p < 0.001) and the percentage of participants who reported “feeling discomfort/tension in the facial muscles when waking up just few times” increased (p = 0.019). Considering SB, there was a significant decrease of the behavior in all samples. The number of “None” report to grinding teeth during sleep or when waking up increased (p = 0.012). An increase in the self-reporting of feeling discomfort in masticatory muscles when awake or sleeping was observed (p = 0.028). The percentage of participants who did “not remember” any AB or SB activity decreased (p < 0.050). The confinement due to COVID-19 resulted in a forced change in dental students’ lifestyles that resulted in an increase of reported AB and a decrease of reported SB. Clinical Significance: In case of confinement periods, students should be encouraged to try normalizing their daily life by creating healthy routines and, by doing so, reducing the possible predisposition to bruxism and its consequences.
Qualitative Methods for Inverse Scattering by an Impedant Crack

The inverse scattering problem for crack identification is increasingly gaining applications in many domains. Examples of applications include non destructive testing, geophysical prospection. The research work in this thesis focuses on the crack identification using qualitative methods, particularly the sampling methods. We use the Linear Sampling Method and the Factorization method to retrieve the geometry of cracks from multi-static far field data in the case of impedance boundary conditions on both sides of the crack embedded in a homogeneous domain. Moreover, an application of the Reciprocity Gap Linear Sampling Method is proposed to retrieve the geometry of cracks embedded in an inhomogeneous domain with the same boundary conditions. A completion method for the Helmholtz-Cauchy problem is also proposed to widen the applicability of the latter method. The efficiency of the proposed methods is shown through numerical experiments for different crack shapes and for several impedance values.
Streptococcal Pyrogenic Exotoxin Genes SpeA and SpeB in Isolates of <i>Streptococcus pyogenes</i> from Children with Pharyngitis, Gezira State, Sudan

Background: Streptococcus pyogenes (group A streptococcus, GAS) is an important human bacterial pathogen. This organism possesses many virulence factors, Streptococcal pyrogenic exotoxinone of these. Aim: Detection of Streptococcal pyrogenic exotoxin SpeA and SpeB in isolated Streptococcus pyogenes. Methods: Tow hundred throat swab samples were collected from children with pharyngitis referred to Pediatric Teaching hospital and ENT hospital Wad medani, Sudan, from January to November 2021. The ques-tionnaire was filled out to collect clinical and demographic data. Throat swabs were collected and processed with the standard microbiological pro-cedure to isolate Streptococcus pyogenes. Antimicrobial susceptibility testing was done on all GAS isolates using the Kirby Bauer disk diffusion method according to clinical laboratory standard institute (CLSI) guidelines. Detection of Spy 1258 gene and Streptococcal pyrogenic exotoxins SpeA and SpeB were done by using Multiplex PCR. Results: Amongst the Tow hundred collected samples fifty-one isolates (25.5%) were identified as S. pyogenes. Antibiotic susceptibility testing showed that all the GAS isolates were sensitive to Azithromycin and Penicillin. Sensitivity to Erythromycin, Gentamicin, Clarithromycin, Amoxicillin and Cephalexin were 88.2%, 86.3%, 45.1%, 41.2%, 13.7%, respectively. SpeA was detected in 17 (33.3%) and SpeB in 48 (94.1%). Conclusion: Streptococcal pyrogenic exotoxin genes SpeA and SpeB were detected in 17 (33.3%) and 48 (94.1%) respectively of Streptococcus pyogenes isolates.
The Glueball; The Fundamental Particle of Non-Perturbative QCD

Theoretical ideas related to the existence of glueballs in QCD are reviewed. These include non-perturbative phenomena such as confinement, instantons, vacuum condensates and renormalons. We also discuss glueball dominance of the trace of the stress-tensor, the mass content of the nucleon and a theorem on the lightest glueball state.
Temporal Summation and Aftersensations of Second Pain in Women with Myofascial Temporomandibular Disorder Differ by Presence of Temporomandibular Joint Pain

Purpose Mechanisms underlying myofascial temporomandibular disorder (mTMD) are poorly understood. One theory is dysfunction in the central mediation of pain, specifically in enhanced facilitatory pain modulation. Because mechanisms leading to central sensitization may differ for joint and muscle pain, this study of mTMD addressed phenotypic heterogeneity by temporomandibular (TM) joint pain in the examination of quantitative sensory testing (QST). Patients and Methods The stimulus dependent increase in second pain (temporal summation (TS)) and associated aftersensations (AS) were examined across groups of women with mTMD with TM joint pain and without, and a demographically matched control group. Results TS was slightly more evident in mTMD without joint pain vs with (p = 0.035), but AS were most robustly persistent in the group with joint pain vs without (p < 0.002). Conclusion While both subgroups demonstrated evidence of central sensitization relative to controls on one of two measures, differences in QST results, if replicated, may point to possible differences in the mechanisms that yield central sensitization. Alternatively, it may represent methodological artifacts that need to be addressed. Therefore, greater consideration should be given to symptom-based phenotypes in studies examining TS and AS.
Assessing the impact of a budget cage technology on Nile Tilapia (Oreochromis niloticus) production in the Bontanga, Golinga and Libga reservoirs in Northern Ghana, Africa

The potential of irrigation reservoirs in northern Ghana to support Nile Tilapia ( Oreochromis niloticus ) production in 1 m 3 budget cages was assessed over six-months in three reservoirs (Bontanga, Golinga and Libga). Fingerlings with a mean weight of 17.0 ± 5.0 g were randomly stocked at 50, 100, 150, 200 and 250 fish per cage in duplicate and fed with a commercial tilapia feed (Raanan, 30% protein level) at 3 to 5% body weight. The results indicated that the lower densities (50 and 100 fish m -3 ) had a higher specific growth rate (SGR) compared to higher densities (150-250 fish m -3 ). The gross yield (7.5–23.1 kg cage -1 ) differed with increasing density on all reservoirs. Consumers in the Tamale Metropolis preferred small sized tilapias (5-6 fish kg -1 ) and were willing to pay US$ 1.40-2.34 kg -1 of fish, while restaurants preferred 2-3 fish kg -1 and were willing to pay US$ 3.27- 3.51 kg -1 . The 200 fish m -3 stocking density was the most profitable and is recommended for cage culture on reservoirs in northern Ghana.
Diagnosis of Schistosomiasis without a Microscope: Evaluating Circulating Antigen (CCA, CAA) and DNA Detection Methods on Banked Samples of a Community-Based Survey from DR Congo

Detection of Schistosoma eggs in stool or urine is known for its low sensitivity in diagnosing light infections. Alternative diagnostics with better sensitivity while remaining highly specific, such as real-time PCR and circulating antigen detection, are progressively used as complementary diagnostic procedures but have not yet replaced microscopy. This study evaluates these alternative methods for the detection of Schistosoma infections in the absence of microscopy. Schistosomiasis presence was determined retrospectively in 314 banked stool and urine samples, available from a previous survey on the prevalence of taeniasis in a community in the Democratic Republic of the Congo, using real-time PCR, the point-of-care circulating cathodic antigen (POC-CCA) test, as well as the up-converting particle lateral flow circulating anodic antigen (UCP-LF CAA) test. Schistosoma DNA was present in urine (3%) and stool (28%) samples, while CCA (28%) and CAA (69%) were detected in urine. Further analysis of the generated data indicated stool-based PCR and the POC-CCA test to be suitable diagnostics for screening of S. mansoni infections, even in the absence of microscopy. A substantial proportion (60%) of the 215 CAA-positive cases showed low antigen concentrations, suggesting that even PCR and POC-CCA underestimated the “true” number of schistosome positives.
Impact of digital transformation on employee engagement at Ceylon Electricity Board in the Northern Province of Sri Lanka

Most of the organizations in the present complex business era have understood the dynamic environment of business and focus on how information technologies are creating digital transformation. To meet the challenges of digital transformation, business firms require greatly encouraged, motivated, and engaged employees at all the level of business processes. In this study, an effort was made to examine the digital transformation and its impact on employee engagement. A sample of 273 staff were selected from Ceylon Electricity Board in Northern Province of Sri Lanka using stratified random sampling method. In this study, an explanatory research design was employed in a cross-sectional time horizon and a survey method was used. The variables were measured using standard questionnaires. Correlation and regression analyses were performed to identify the association between the variables and ANOVA and Independent sample t-test were performed to compare means. The study revealed that the dimensions of digital transformation namely customer service, operational efficiency and business modelling positively impact employee engagement. The research provides useful understandings for administrators to realize the connection among digital transformation and employee engagement and how far each of the dimensions of digital transformation contributes to increase employee engagement. Based on the results, recommendations are made to enhance the employee engagement in the workplace.
Technical Change, Task Allocation, and Labor Unions

We propose a novel framework that integrates the “task approach” for a more precise production modeling into the search-and-matching model with lowand high-skilled workers, and wage setting by labor unions. We establish the relationship between task reallocation and changes in wage pressure, and examine how skillbiased technical change (SBTC) affects the task composition, wages of both skill groups, and unemployment. In contrast to the canonical model with a fixed task allocation, low-skilled workers may be harmed in terms of either lower wages or higher unemployment depending on the relative task-related productivity profile of both worker types. We calibrate the model to the US and German data for the periods 1995-2005 and 2010-2017. The simulated effects of SBTC on low-skilled unemployment are largely consistent with observed developments. For example, US low-skilled unemployment increases due to SBTC in the earlier period and decreases after 2010.
Impacts of Continuous and Intermittent Use of Bovine Colostrum on Laying Japanese Quails: Egg Performance and Traits, Blood Biochemical and Antioxidant Status

Simple Summary Quail is used in cookery, but mainly for its egg production around the globe, and sustainable poultry farming practices have been searched. The use of colostrum (beestings or first milk from cows) in quails’ diet can play an important role in providing probiotics and reducing the need for antibiotics, which, in addition to better quail performance, is effective in reducing environmental impacts. The results of the current research show that the continuous use of bovine colostrum (BC) in laying quails’ diets has beneficial effects on their performance, egg traits, blood indexes and antioxidant status. Abstract The Japanese quail (Coturnix japonica) is farmed for its eggs and meat across the globe. A series of experiments were conducted to evaluate the effect of the permanent or intermittent use of different levels of BC (bovine colostrum) on the egg performance and traits, carcass characteristics, blood biochemical and antioxidant status of laying Japanese quails. In this study, 200 laying quails were used for a duration of six weeks (week 24 to 30) to measure the selected parameters. Treatments included: (1) control (without BC); (2) 2% continuous BC; (3) 4% BC permanently; and (4) and (5) 2% and 4% BC intermittently (every other week), respectively. According to the results, performance, egg quality, carcass traits, biochemical indices and antioxidant status of BC-fed (continuous and intermittent mode) quails were improved compared to the control-diet-fed birds (p < 0.01). Per our observations, quails fed daily with 4% BC had the highest performance, best egg and carcass quality traits, best blood composition and best antioxidant status of serum, although the same parameters were also improved in birds fed intermittently with 4% BC. The final conclusion is that, although quails fed daily with 4% BC showed the best performance, intermittent feeding exerted comparable effects. Therefore, the intermittent-feeding approach could benefit the birds when colostrum preparation is limited due to the high cost of the related process. This approach could improve the economics of poultry breeding while reducing environmental problems, such as antibiotic resistance.
SUZAKU OBSERVATION OF THE BRIGHTEST BROAD-LINE RADIO GALAXY 4C 50.55 (IGR J21247+5058)

We report the results from a deep Suzaku observation of 4C 50.55 (IGR J21247+5058), the brightest broad-line radio galaxy in the hard X-ray (>10 keV) sky. The simultaneous broadband spectra over 1–60 keV can be represented by a cutoff power law with two layers of absorption and a significant reflection component from cold matter with a solid angle of Ω/2π ≈ 0.2. A rapid flux rise by ∼20% over 2 × 104 s is detected in the 2–10 keV band. The spectral energy distribution suggests that there is little contribution to the total X-ray emission from jets. Applying a thermal Comptonization model, we find that corona is optically thick (τe ≈ 3) and has a relatively low temperature (kTe ≈ 30 keV). The narrow iron-K emission line is consistent with a picture where the standard disk is truncated and/or its inner part is covered by optically thick Comptonizing corona smearing out relativistic broad-line features. The inferred disk structure may be a common feature of accretion flows onto black holes that produce powerful jets.
