COVID-19 Pandemic: Management emergencies response and lesson learned from the Globe

WHO released the COVID-19 Pandemic that hit at least 223 countries and territories and global confirmed cases reached nearly 103,631,793 people and 2.17% of them died. Countries such as China, America, Europe, Belgium, Taiwan and Brunei Darussalam, have made various ways and efforts to fight the COVID-19 pandemic, which can be taken as potential practices and lessons. This literature review aims to investigate best practices that can be learned in emergency response and handling of the COVID-19 pandemic from various global countries that can be taken as learning and common good. This study method is a literature review, by accessing several peer-reviewed literature articles between 2020 and 2021 related to emergency response and lessons learned of the COVID-19 Pandemic. Based on the literature review that has been analysed, practices and lessons learned in overcoming the COVID-19 pandemic can be identified, including: extensive public health infrastructure, establishment of temporary hospitals, effective isolation methods, increased social distancing, surveillance systems with digital technology, community involvement, and lock-down as a last alternative to inhibit the spread, as well as a crisis management approach from an Islamic perspective. It can be concluded that emergency response in decision making and policy is a very influential factor in the success of controlling the COVID-19 pandemic. Keywords— lesson learned, COVID-19, emergency response, Islamic risk management.
On the effect of solid particle sphericity on the tangential velocity in a cyclone separator

Abstract The Eulerian–Lagrangian computational approach is employed for the particles motion simulation within the cyclone separator. The 3 D Reynolds-averaged Navier–Stokes equations are utilized to calculate the flow field. CFD simulations are verified first with the available numerical and experimental data in the literature, then they are verified with the particle-laden flow experimental measurements carried out in a cyclone separator. The Reynolds Averaged Navier-Stokes equations (RANS) implying the realized k–ε turbulence model is used in the simulation of the gas phase, whereas the simulation of the particulate phase is performed utilizing 3-D particle tracking technique. The numerical model accounts for particle sphericity by applying three separate equations for the drag coefficient. The tangential velocity in the cyclone is obtained numerically for different particle sizes, sphericity and particle mass loadings. Verification of the numerical findings is performed by means of experiments, in which, the tangential velocity is measured using a five-hole probe. The experimental measurements show a considerable agreement with the available numerical data simulating particle laden flow for non-spherical particles in a cyclone.

Strategies for spectrum usage measurements

The design of strategies to measure spectrum usage is systematized to a degree by considering the electrospace dimensions. 'Electrospace' is used to describe the portion of the universe that a radio wave occupies, and its dimensions are frequency, location, direction, polarization, and time. A strategy that considers each of the dimensions individually serves as the starting point for planning the actual measurement program. Several examples of measurement programs are described, showing a wide range of measurement and signal processing functions resulting from difference in the signal populations in the respective frequency bands and different requirements for data. Since the details of the measurement process can vary widely, interpretation of the data must be carefully matched to the measurements. <<ETX>>
Assessment of the value of measuring soluble fms-like tyrosine kinase-1 and placental growth factor levels following administration of tadalafil to treat fetal growth restriction

Abstract Purpose The aim of this study was to measure the blood levels of soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) before and after tadalafil treatment in patients with fetal growth restriction. Materials and methods Maternal blood was collected from 13 women before and 2 weeks after tadalafil administration in the TADAFER II trial. The tadalafil treatment was conducted in addition to the conventional FGR treatment. As a control, maternal blood was also collected from 11 women before and 2 weeks after conventional treatment for fetal growth restriction. Blood sFlt-1 and PlGF were measured and the sFlt-1/PlGF ratio was calculated. Student’s t-test was used to statistically analyze differences in the sFlt-1 and PlGF levels, and in the sFlt-1/PlGF ratios. Results In both treatment groups, the levels of sFlt-1 and PlGF before and after treatment were not significantly different from each other. The sFlt-1/PlGF ratio was 2.0 ± 1.0 before and 17.6 ± 11.3 after treatment in the control group (p=.04). The sFlt-1/PlGF ratio was 2.2 ± 1.1 before and 22.2 ± 10.6 after tadalafil treatment in the tadalafil group (p=.06). The sFlt-1/PlGF ratios before and after tadalafil treatment were significantly increased in the control group. In both treatment groups, the sFlt-1/PlGF ratios before and after treatment were less than 38. Conclusions We conclude that the levels of sFlt-1 and PlGF were not significantly different as a result of tadalafil treatment. Further studies are needed to understand the mechanism of action of tadalafil in the treatment of fetal growth restriction.
A comparison of Saudi and United States faculty use of information and communication technology tools

The purpose of this descriptive and comparative study was to identify Information and Technology Communication (ICT) tools used by Saudi faculty and United States faculty, and to investigate relationships between their perceptions of ICT applications and ICT use. A questionnaire was sent to 292 Saudi faculty from six Saudi universities and 253 US faculty from five universities. The questionnaire gathered information about the use of and attitudes toward ICT applications. Results found that 65% of the United States faculty taught part or all of a course online as compared to only 26% of Saudi faculty. Saudi faculty used Social Media applications significantly more often than US faculty. Saudi faculty also reported using Google Documents, Photos and Website links significantly more often than US faculty while US faculty used podcasts and text documents significantly more often. Results from a path analysis of the relationships between ICT attitudes and actual ICT use based on Davis’ (1993) TAM framework found that for Saudi faculty, system was the only variable significantly related to actual ICT Use. Ease of Use was significantly related to Perceived Value while Perceived Value was significantly related to Attitude Toward ICT Use. For US faculty, again, system was the only variable to have a significant relationship with Actual ICT use. Perceived Value was found to have a significant effect on Attitude Toward Use of ICT tools. The larger relationship between system use and actual ICT tool use for US faculty suggests that they had more access thus more experience using ICT tools than Saudi faculty. In addition, differences in attitudes toward ICT between Saudi and US faculty may be due Saudi faculty’s primary use of social media and email applications as compared to US faculty’s use a variety of more complex ICT applications including Audio. Overall results from this study suggest that Saudi faculty would benefit from training in the use of a variety of ICT application in addition to social media and email within the context of Learning Management Systems while US faculty would benefit from training in the use of social media applications as an instructional tool.
Toward Digital Picture Books for a New Generation of Emergent Readers

The study tests the efficacy of a new sort of digital picture book. It includes camera movements to guide children’s visual attention through the pictures and the possibility to control page-turning and the pace at which the camera moves through pictures. There were 56 participants (Mage = 60.34 months, SD = 6.24) randomly assigned to three conditions: still images, camera movements (no control over pace), and camera movements (control over pace). For the 50% of children least proficient in language skills, sparingly adding well-chosen camera movements to the illustrations helps children understand the story. In addition, the camera movements’ effect can be enhanced by enabling control over the pace at which new information appears. Particularly the 50% low-language proficiency children benefited from camera movements and spending more time processing information.
Bouldering: One of the last sports defying technology? Interview with Kilian Fischhuber

Bouldering is a form of rock climbing, without belaying up to a height from which the climber can still jump off and land safely. Bouldering ranges from a sequence of a few hard moves to more than 100 moves (Figure 1). The history of modern bouldering starts at the end of the 1950s with John Gill, who, coming from a gymnastics background, translated his technical und physical skills to climbing. Initially confined to a welcome possibility for isolated technique and power training, in the 1990s, bouldering developed into an autonomous alpine climbing discipline with globally growing popularity. Currently, bouldering can be practiced both on artificial climbing walls (indoors and outdoors) and natural rock. Since 1998, bouldering has been an official competition discipline held according to the rules of the International Federation of Sport Climbing. The primary challenge in competition bouldering is the accomplishment of hard, single moves and complex motion sequences. This requires, in particular, coordination, flexibility, and maximal strength. The aim is to master as many boulders in as few attempts as possible. One reason for the popularity of bouldering certainly is the ‘minimalism’ of the sport. Technically, it suffices to be equipped with climbing shoes, chalk for drying the fingers, and brushes for cleaning holds and steps. Chalk (chemically magnesium carbonate MgCO3) is a slightly alkaline substance, which dries the hands by forming magnesium carbonate hydroxides, thereby increasing the friction between skin and rock. It is also used in other sport disciplines; for example, bodybuilding, weightlifting, or gymnastics. Because of the high dust exposure in climbing gyms, alternatives are sought. One of them is liquid chalk––magnesium carbonate in alcohol–– which evaporates at the skin surface, further drying the skin and leaving a thin chalk layer. Other alternatives are hygroscopic substances inside absorptive balls, like the Eco Ball (Metolius Climbing, Bend, Oregon, USA). Unlike on limestone, chalk has negative effects on sandstone rocks, by filling up the surface pores. Therefore, in some sandstone areas, like Fontainebleau (France), climbers traditionally use colophony (resin, pof) instead of chalk. Crash pads enable safe landings, even on uneven ground. The crash pads are equipped with a carrying system and can be transported to the rocks folded or rolled (Figure 2). Protected by a strong sheath, the crash pad consists of several layers of stiff and soft foam absorbing the impact energy of a falling climber. The shoes are of special importance to climbing. Shoes are a good example of the technological evolution in sport climbing. In the mid-1970s, the first modern climbing shoes looked like baseball shoes with slick rubber soles. Compared to those, today’s climbing shoes are characterized by a futuristic design. Notable manufacturers provide a great variety of designs for beginners to experts.
Determinants of Foreign Capital Inflows in Emerging Markets: The Role of Institutional Quality

Purpose: The purpose of the study was to examine the key determinants of foreign direct investment (FDI) and foreign portfolio investment (FPI) in emerging market economies, with greater emphasis placed on the impact of institutional quality. Design/Methodology/Approach: The study applied a panel data system generalised method of moments (GMM) model using annual data spanning the period 2007 to 2017, in respect of 12 emerging market economies. To measure institutional quality, the study adopted the Worldwide Governance Indicators, and constructed a composite index for institutional quality using the Principal Components Analysis (PCA) method. Findings: The results revealed that FDI in the selected emerging markets was attracted by institutional quality and economic growth. Capital account openness, institutional quality and economic growth were positive determinants of FPI. However, stock market development stood out as the key determinant factor for foreign capital inflows. Implications/Originality/Value: The implications of these findings are that, in their pursuit of foreign capital inflows, these emerging markets should continue to liberalise their economies and develop their financial markets. Importantly, such developments must be coupled with the strengthening of the formal governance institutions. Robust institutions would not only curb institutional weaknesses that deter international capital inflows, but would also insulate emerging markets from unfavourable effects of volatile capital flows.
In vitro antiproliferative, antioxidant and anti-inflammatory activities and phenolic profile of Centaurea saligna (K.Koch) Wagenitz

: In this study, methanol extract (CSM) and their hexane (CSH), chloroform (CSC), ethyl acetate (CSEA) and aqueous methanol fractions (CSAM) prepared from aerial parts of Centaurea saligna (K.Koch) Wagenitz were investigated for in vitro antiproliferative, anti-inflammatory and antioxidant activity. Anticancer, antioxidant, anti-inflammatory activities of these extracts were carried out by MTT, DPPH-ABTS, 5-lipoxygenase methods, respectively. Methanol extract and its fractions of C. saligna were evaluated for their cytotoxicity against MCF-7, A549, HeLa, HT-29, PC-3 cell lines at a concentration of 50 µg / ml. Total flavonoid and phenolic contents of extracts were detected by AlCI 3 and Folin-Ciocalteu methods, respectively. Analysis of phytochemical of CSEA, showing a strong anti-inflammatory activity with good antioxidant activity, was performed by LC-MS/MS. CSC exhibited the best antiproliferative activity against HeLa, HT-29, MCF-7 cell lines with 50.18%, 46.88%, 45.42% mortality, respectively. CSEA showed the highest antioxidant activity with IC 50 values of 82.05 µg/ml and 108.4 µg/ml against ABTS and DPPH radicals, respectively. The highest total phenolic amounts have been determined in CSEA with value of 379.2 mg GAE/g extract. In the same way, the highest total flavonoid amounts have been observed in CSEA with values of 170.3 mg QE/g extract. CSEA showed strong anti-inflammatory activity with IC 50 value of 0.10 µg/ml when compared to indomethacine as standard (22.39 µg/ml). Analysis of CSEA by LC-MS/MS revealed that the major compounds were quinic acid, 5-caffeoylquinic acid, apigenin C-hexoside-C-pentoside, p-coumaroylquinic acid, quercetin glucoside, di-caffeoylquinic acid, isorhamnetine glucoside, isorhamnetin glucuronide and isorhamnetin derivative. These results proved that CSEA has significant anti-inflammatory and antioxidant activity and CSC has good antiproliferatif activity. Also, the results demostrate that CSEA and CSC are a good source for further bioactivity-guided isolation in discovering new active antioxidant, anti-inflammatory and antiproliferative compounds.
Digital Parenting of Emerging Adults in the 21st Century

In emerging adulthood, when many young people are away from their families for the first time, mobile phones become an important conduit for maintaining relationships with parents. Yet, objective assessment of the content and frequency of text messaging between emerging adults and their parents is lacking in much of the research to date. We collected two weeks of text messages exchanged between U.S. college students (N = 238) and their parents, which yielded nearly 30,000 parent-emerging adult text messages. We coded these text message exchanges for traditional features of parent-emerging adult communication indexing positive connection, monitoring and disclosures. Emerging adults texted more with mothers than with fathers and many messages constitute parental check-ins and emerging adult sharing regarding youth behavior and well-being. Findings highlight that both the frequency and content of parent-emerging adult text messages can be linked with positive (perceived text message support) and negative (perceived digital pressure) aspects of the parent-emerging adult relationship. The content of parent-emerging adult text messages offers a valuable, objective window into the nature of the parent-emerging adult relationships in the digital age of the 21st century.
A meta-analysis of XRCC1 single nucleotide polymorphism and susceptibility to gynecological malignancies

Abstract Background: Gynecological malignant tumor is a serious threat to women's health, cervical cancer, endometrial cancer and ovarian cancer are the most common. The eponymous protein encoded by the XRCC1 (X-ray repair cross complementation 1) gene is an important functional protein in the process of single-stranded DNA damage. Non-synonymous mutations of XRCC1 gene cause amino acid sequence changes that affect protein function and DNA repair ability, and may affect the interaction with other DNA repair proteins, leading to increased risk of tumor development. Many studies have assessed the association between XRCC1 gene polymorphism and the risk of cancer in the female reproductive system, but the results have been inconclusive. In this study, the relationship between XRCC1 Arg399Gln, Arg194Trp, Arg280His single nucleotide polymorphisms and susceptibility to gynecological malignancies was further explored by meta-analysis. Methods: English database: Pubmed, Medline, Excerpta Medica Database, Cochrance, etc; Chinese database: China national knowledge infrastructure, Wanfang Database, etc. STATA14 was used for statistical analysis, such as odd ratio (OR) value, subgroup analysis, heterogeneity test, sensitivity analysis, and publication bias. Results: In gynecologic cancers, the allele frequency difference of Arg399Gln case control group was statistically significant (GvsA: P = .007). There was no significant difference in allele frequency in the Arg194Trp and Arg280His case control groups (P = .065, 0.198). In different gene models, Arg399Gln was significantly correlated with gynecologic cancers susceptibility (GGvs AA: OR 0.91; 95% confidence interval [CI], 0.85 0.98); Arg194Trp was significantly correlated with gynecologic cancers susceptibility (CCvs TT: OR 0.94; 95% CI 0.88,1.00; CCvs CT: OR 0.97; 95% CI 0.90, 1.05); Arg280His was significantly correlated with gynecologic cancers susceptibility (GGvs AA: OR 0.98; 95% CI 0.94, 1.02; GGvs GA: OR 1.00;95% CI 0.97, 1.04). In the subgroup analysis, Arg399Gln and Arg194Trp were significantly correlated with gynecologic cancers susceptibility in the Asian race (P = .000, 0.049). In the analysis of different cancer subgroups, Arg399Gln and cervical cancer susceptibility were statistically significant (P = .039). Arg194Trp and endometrial cancer susceptibility were statistically significant (P = .033, 0.001). Conclusions: XRCC1 Arg399Gln, Arg194Trp, Arg280His single nucleotide polymorphisms were associated with gynecologic cancer susceptibility. Arg399Gln genotype was statistically significant in relation to cervical cancer susceptibility. Arg194Trp genotype was statistically significant in relation to endometrial cancer susceptibility.
The video feedback viewing in novice weightlifters: Total control strategy improves snatch technique during learning

This study aimed at comparing the efficiency of two viewing control strategies, total control versus partial control, in correcting the snatch technique in school-aged boys (10–12 years old). Thirty-nine participants, with 2 months of weightlifting training experience, were divided into three groups: total control, partial control, or a control group. The Kinovea version 0.8. 15 software was used to measure the kinematic parameters of the snatch technique before (T0) and after six learning sessions (T1). Following the learning sessions, total control group showed greater improvements for all kinematic parameters compared with the partial control and control group (e.g., the horizontal displacement (i) in the first pull (Δ Dx2: 18.17 ± 26.75%, p < 0.01, d = 0.83), (ii) between the first and the second pulls (Δ DxV: 25.97 ± 18.02%, p < 0.001, d = 1.52) and from the most forward position to the catch position (Δ DxL: 19.98 ± 21.60%, p < 0.01, d = 1.36), while the partial group improved only on the Dx2 (Δ Dx2 = 21.53 ± 20.40%, p < 0.01, d = 0.86). The present results indicate that the intensive use of the interactive features (e.g. pause, play, forward, and backward) and the asked questions during the first learning phase were essential for the improvement of the snatch technique. These findings have potential practical implications for coaching and physical education teaching.
Perceived neighborhood disorder, social cohesion, and depressive symptoms in spousal caregivers

Abstract Objectives Prior research into the factors linked to mental health of caregivers of older adults have largely focused on individual- or household-level characteristics, but neighborhood supports and stressors may also matter for caregiver mental health. The current study fills this knowledge gap by examining the association of neighborhood social cohesion and disorder and depressive symptoms among spousal caregivers. Method We used data from the 2006 to 2016 waves of the Health and Retirement Study, which include 2,322 spousal caregivers. Negative binomial regression models were estimated to examine the association of perceived neighborhood social cohesion and disorder with depressive symptoms. Results A higher level of perceived neighborhood social cohesion was associated with fewer depressive symptoms (b = –0.06, 95% CI: −0.10, −0.02). On the other hand, greater perceived neighborhood disorder was associated with more symptoms (b = 0.04, 95% CI: 0.01, 0.08). The association of perceived social cohesion with depressive symptoms remained even after controlling for perceived disorder, but neighborhood disorder was no longer associated with depressive symptoms after accounting for reported neighborhood social cohesion. Conclusions This study suggests neighborhood supports and stressors matter for caregiver well-being. Neighborhood-based social support may be particularly important for caregivers as they navigate the challenges caregiving for an aging spouse can bring. Future studies should determine if enhancing positive characteristics of the neighborhood promotes well-being of spousal caregivers.
