Published: February 2021

We explore several ways to dissect brightest cluster galaxies (BCGs) and their surrounding intracluster light (ICL) using a surface brightness (SB) cut, a luminosity cut, excess light above a de Vaucouleurs profile, or a double Sérsic decomposition. Assuming that all light above

is attributable to the ICL, we find that an average fraction of

of all diffuse light centered on the BCG belongs to the ICL. Likewise, if we assume that all light fainter than

mag arcsec−2 belongs to the ICL, the average ICL fraction is

. After fitting a de Vaucouleurs profile to the inner parts of the SB profile, we detect excess light at large radii, corresponding to an average ICL fraction of

. Finally, by decomposing the SB profile into two Sérsic functions, we find an average ICL fraction of

associated with the outer Sérsic component. Our measured ICL and BCG+ICL luminosities agree well with predictions from high-resolution simulations where the outer Sérsic component traces the unrelaxed, accreted stellar material. BCG and ICL properties defined in this way are correlated with cluster parameters to study the coevolution of BCGs, ICL, and their host clusters. We find positive correlations between BCG+ICL brightness and cluster mass, cluster velocity dispersion, cluster radius, and integrated satellite brightness, confirming that BCG/ICL growth is indeed coupled with cluster growth. On average, the ICL is better aligned than the BCG with the host cluster in terms of position angle, ellipticity, and centering. That makes it a potential dark-matter tracer.

Published: February 2021

Properties of the inner heliosheath (IHS) plasma are inferred from energetic neutral atom (ENA) observations by ∼1 au spacecraft. However, the Compton–Getting effect due to the plasma velocity relative to the spacecraft is rarely taken into account, even though the plasma speed is a significant fraction of the ENA speed. In this study, we transform Interstellar Boundary Explorer (IBEX) ENA spectra to the IHS plasma frame using flow profiles from a 3D heliosphere simulation. We find that proton spectra in the plasma frame are steeper by ∼30% to 5% at ∼0.5 to 6 keV, respectively, compared to ENAs in the spacecraft frame. While radial plasma flows contribute most to the Compton–Getting effect, transverse flows at mid/high latitudes and the heliosphere flanks account for up to ∼30% of the frame transformation for IBEX-Hi at ∼0.7 keV and up to ∼60% for IBEX-Lo at ∼0.1 keV. We determine that the majority of IHS proton fluxes derived from IBEX-Hi measurements in 2009–2016 are statistically consistent with power-law distributions, with mean proton index ∼2.1 and standard deviation ∼0.4. We find significantly fewer spectral breaks in IBEX observations compared to early analyses, which we determine were a product of the “ion gun” background prevalent in ∼2009–2012 before corrections made by McComas et al. in subsequent data releases. We recommend that future analyses of the IHS plasma utilizing ENA measurements take into account the Compton–Getting effect including radial and transverse flows, particularly IBEX and Interstellar Mapping and Acceleration Probe measurements below ∼10 keV.
Atmosphere Escape Inferred from Modeling the Hα Transmission Spectrum of WASP-121b
Authors: Yan Dongdong , Guo Jianheng , Huang Chenliang , Xing Lei
Published: February 2021

The escaping atmospheres of hydrogen driven by stellar X-ray and extreme ultraviolet (XUV) have been detected around some exoplanets by the excess absorption of Lyα in the far-ultraviolet band. In the optical band the excess absorption of Hα is also found by ground-based instruments. However, it is not certain if the escape of the atmosphere driven by XUV can result in such absorption. Here we present the XUV-driven hydrodynamic simulation coupled with the calculation of detailed level population and the process of radiative transfer for WASP-121b. Our fiducial model predicts a mass-loss rate of ∼1.28 × 1012 g s−1 for WASP-121b. Due to the high temperature and Lyα intensity predicted by the fiducial model, many hydrogen atoms are populated into the first excited state. As a consequence, the transmission spectrum of Hα simulated by our model is broadly consistent with the observation. Compared with the absorption of Hα at different observation times, the stellar XUV emission varies in the range of 0.5–1.5 times fiducial value, which may reflect the variation of the stellar activity. Finally, we find that the supersonic regions of the planetary wind contribute a prominent portion to the absorption of Hα by comparing the equivalent width of Hα, which hints that a transonic outflow of the upper atmosphere driven by XUV irradiation of the host star can be detected by a ground-based telescope and that Hα can be a good indicator of escaping atmosphere.

We present analysis of IR and optical spectroscopy of Jupiter-family comet (JFC) 46P/Wirtanen obtained in 2019 January, when the comet had sufficient geocentric velocity to enable studies of the hypervolatiles CO and CH4, as well as [O i] emission. These species could not be studied near closest approach in mid-December because there was insufficient Doppler shift to separate the cometary emission from their corresponding telluric absorption lines. We employed the [O i] observations as a proxy for the CO2/H2O ratio, as CO2 cannot be observed directly from the ground, and space-based assets sensitive to CO2 were not able to observe 46P during this apparition. We focused our analysis on H2O, CO, CH4, C2H6, CH3OH, and CO2 (via [O i] emission). We detected strong emissions from H2O, C2H6, and CH3OH. Over the 3 nights, we found evidence for changing mixing ratios, mostly due to a variable H2O production rate. In 46P, C2H6 and CH3OH are enriched compared to cometary averages, with mixing ratios relative to H2O of ∼1% and ∼3%, respectively. Measurements of CH4 and CO have been especially rare in JFCs. We report significant 3σ upper limits on CH4/H2O < 0.97% and CO/H2O < 0.54%. They place CH4 being near-average or depleted, and CO being strongly depleted in 46P compared with Oort cloud comets. 46P has comparable CO/H2O to the few other measurements in JFCs, but enriched in C2H6 and CH3OH. Our inferred CO2/H2O mixing ratio is ∼15%, though accounting for systematic uncertainties from the lack of knowledge of [O i] photochemistry means a value between 10% and 20% is likely. The compositional profile of 46P is similar to another small, hyperactive comet: 103P/Hartley 2. The mechanism of CO2-driven water-rich ice grain production proposed for 103P/Hartley 2 may be operating on 46P as well.

Authors: Aprianto Dirga Rachmad , Susilo Rahadian Indarto , Wahyuhadi Joni , Immadoel Haq Irwan Barlian
Published: February 2021

BACKGROUND: Meningioma is mostly benign tumor (World Health Organization Grade 1) and surgery remains the best option in treating symptomatic or enlarging meningiomas where total removal of the tumor is the goal of surgery. Radiation therapy has shown to be effective to cease the growth of the tumor, but not in tumor regression. Adjuvant therapy may treat patients with recurrence or unresectable meningiomas yet the uses of hormone therapy, immunotherapy, or chemotherapy had many results and were not consistently effective. Hydroxyurea has promising results in patients with meningiomas.
AIM: This study analyzed the efficacy and safety of hydroxyurea for the treatments of recurrence or unresectable meningiomas.
MATERIALS AND METHODS: The study adapted PRISMA guidelines by searching electronic databases, PUBMED, Cochrane, and JNS in August 2020 and was full-text observational study or randomized control trial presented as PICO and assessed using the risk-of-bias assessment tool.
RESULTS: A total of six articles (157 patients with meningioma) were reviewed from the total of 425. Hydroxyurea was administered orally for 28 days continuously and repeated every 28 days or after recovery with various dosages in six studies.
DISCUSSION: Administration of hydroxyurea showed a varied stable disease rate ranging from 30 to 69% with a median progression-free survival med varying between 2 and 27.75 months. The studies performed oral hydroxyurea administration at a dose of 20–30 mg/kg body weight/day or 1000 mg/m2/day. However, the adverse events (AEs) that appear also, based on literature, are not much different from other chemotherapy administrations.
CONCLUSION: Patients with unresected and recurrent meningiomas have limited treatment options due to difficulty for surgical management. However, this study offers another perspective addressing the efficacy and safety results with the use of hydroxyurea. Overall, hydroxyurea showed good outcomes, particularly in low-grade meningioma, with relatively low AEs. Further combination treatment may be used as a multimodal therapy.

A Latent Profile Analysis to Categorize and Describe Athletes Based on Factors Related to Concussion Disclosure
Authors: Milroy Jeffrey , Sanders Lindsey , Mendenhall Brandon , Dudley William B. , Wyrick David
Published: February 2021

Context

Collegiate student-athletes continue competing after experiencing symptoms of a concussion. Self-report of concussion symptoms is a critical element of the recovery process. Identifying factors related to concussion disclosure can aid in encouraging self-reporting.

Objective

To use latent profile analysis to categorize and describe athletes based on factors related to concussion disclosure.

Design

Cross-sectional study.

Setting

Web-based survey.

Patients or Other Participants

A total of 2 881 (52.4% female; 65.3% in-season; 40% collision sport) student-athletes from 16 National Collegiate Athletic Association member institutions.

Main Outcome Measure(s)

Student-athlete concussion expectations, attitudes, and norms were the profile variables and reporting intentions served as the distal outcome variable. We conducted latent profile analysis using select profile variables to determine the optimal number of classes. Differences in concussion-reporting intentions by profile assignment were then examined. Lastly, the extent to which a student-athlete's sex, season status, and level of contact predicted his or her intentions to report a concussion within each profile was investigated.

Results

Five unique student-athlete profiles emerged, including 1 profile that was most risky and another that was least risky. Females had significantly higher odds of being in the least risky profile. Those participating in collision sports had significantly higher odds of being in the top 2 most risky profiles. Contact-sport and in-season athletes were less likely to be in the least risky profile.

Conclusions

With a better understanding of student-athlete profiles, athletic trainers have an opportunity to encourage concussion disclosure. Prompt disclosure would allow student-athletes to begin the return-to-play protocol in a more timely manner.
Gender differences in the association between social support and caregiver alcohol use in posttraumatic stress disorder of east Taiwan adolescents
Authors: Kao Ching-Yi , Bradshaw Tyler , Mazarakis Theodoris
Published: February 2021

Objectives:

This study investigates traumatic experiences in a sample of high-risk Taiwanese adolescents in rural areas of Taiwan; correlation with psychosocial factors is assessed with focus on social support and caregiver alcohol use.

Materials and Methods:

This was a cross-sectional study using stratified cluster sampling. Structured questionnaires were used to collect demographic characteristics, social support (Taiwan Relationship Inventory for Children and Adolescents), and posttraumatic stress disorder (PTSD) symptoms (Chinese version of UCLA-PTSD Reaction Index) from a sample of 751 adolescents (54.6% females) with 61.2% response rate in high schools in Hualien County, Taiwan.

Results:

Girls with trauma experiences manifested significantly higher PTSD scores, concurrent with higher number of traumatic events (TE), while the likelihood of reporting trauma and subsequent PTSD symptoms was similar in both genders. Increased risk of reported trauma and PTSD in adolescent Taiwanese is strongly associated with caregiver alcohol use and lack of social support, particularly in girls.

Conclusion:

We found that girls reported higher numbers of TE which was concurrent with significantly higher PTSD scores. Early detection of alcohol use disorders among caregivers as well as assessment of quality of family interaction would benefit at risk adolescents through specifically tailored interventions to address these factors.
Chinese herbs and acupuncture to improve cognitive function in Alzheimer's disease
Authors: WuLi Wei , Harn Horng-Jyh , Chiou Tzyy-Wen , Lin Shinn-Zong
Published: February 2021

Alzheimer's disease (AD) is a neurodegenerative disease with a variety of causes. Traditional Chinese medicine (TCM), which includes the two main approaches of acupuncture and herbal medication, views the human body as a self-controlled system network. Fundamental theories, including “qi,” the five elements, and the theory of viscera, form the basis for classification. Diseases in humans are considered to be caused by an imbalance of “yang qi” and “yin qi” that lead to the nonhomeostasis of organs. Acupuncture is derived from 12 main meridians and 365 acupuncture points characterized by “blood and qi.” Needling of different positions corresponds to specific disease treatments to increase qi. Treatment with Chinese herbal medicines is based on syndrome differentiation characterized as “Zheng” which differs from the cause orientation approach of Western medicine. In this article, we review basic and clinical research studies that describe TCM herbs and acupuncture for the treatment of AD. Moreover, we propose that these two approaches be integrated to improve the outcomes for AD patients.

Published: February 2021

The search for more nutritionally active sources among forest products has called for the analysis of the phytochemical content and antioxidant activity of Vitex doniana (black plum) sweet fruit. Although, Vitex doniana sweet fruit had been known to be very useful among people across tropical Africa and beyond, but there is lack of adequate data on its phytochemical and antioxidant composition. The fresh fruits of Vitex doniana sweet were collected from several randomly selected trees in a farm site in Uromi metropolis, Esan North-East Local Government Area of Edo state and then processed into an extract in form of syrup. The phytochemical and antioxidant profile of Vitex doniana sweet fruit were investigated to ascertain its health benefits. The antioxidant activity was done by measuring the scavenging effect of the fruit and ascorbic acid on 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical. The scavenging ability of the fruit showed a concentration-dependent activity profile. It increased with an increase in concentrations. The IC50 value of the fruit was found to be 245.8 µg/mL and that of ascorbic acid 2.175 µg/mL, indicating that the fruit has very little antioxidant activity comparable to ascorbic acid (control). The study also revealed that the fruit contains tannins, saponins, cardiac glycosides, alkaloids, flavonoids, terpenoids and steroids.
EXPLORATION OF INTERCALATED KAOLINITE CLAY FOR THE UPTAKE OF BASIC DYE BY ADSORPTION − EQUILIBRIUM, KINETICS AND THERMODYNAMIC STUDIES

Published: February 2021

Dyes are complex and sensitive organic chemicals which exposes microbial populations, aquatic lives and other living organisms to its toxic effects if their presence in water bodies or industrial effluents are not properly handled. This work therefore, comparatively studied the adsorption efficiencies of natural raw kaolinite (NRK) clay adsorbent and dimethyl sulphoxide (DMSO) faciley intercalated kaolinite clay (DIK) adsorbent for batch adsorption of Basis Red 2 (BR2) dye. The impact of varying the contact time, temperature and other operating variables on adsorption was also considered. The two adsorbents were characterized using SEM images, FTIR and XRD patterns. Linear and non-linear regression analysis of different isotherm and kinetic models were used to describe the appropriate fits to the experimental data. Error analysis equations were also used to measure the goodness-of-fit. Langmuir isotherm model best described the adsorption as being monolayer on homogenous surfaces while Kinetic studies showed that Elovich model provides the best fit to experimental data. The adsorption capacities of NRK and DIK adsorbents for the uptake of BR2 were 16.30 mg/g and 32.81 mg/g, respectively (linear regression) and 19.30 mg/g and 30.81 mg/g, respectively (non-linear regression). The thermodynamic parameter, ∆G showed that BR2 dye adsorption onto the adsorbents were spontaneous. DIK adsorbent was twice efficient compared with NRK for the uptake of BR2 dye.
The use of Instrumental Enrichment as a method to teach the analysis of the population pyramid to Grade 7 Geography students.
Authors:   St Mary’s DSG, South Africa, Brandt Juliet
Published: February 2021

Action research was conducted to improve the teaching of the analysis of the population pyramid to Grade 7 female Geography students. Instrumental Enrichment was selected as a tool to teach the analysis of the population pyramid. Firstly, the concept of a population pyramid was introduced and taught using an existing teaching method and a baseline assessment was conducted. Instrumental Enrichment was then introduced, and students used the tool to analyse four population pyramids. A concluding assessment measured the improvement in students’ ability to analyse the population pyramid. The use of Instrumental Enrichment did enhance the students’ understanding of the population pyramid. However, they were not able to use it consistently and independently. This agrees with Willingham (2009) that students remember what they think about and the findings of Bellaera (2017) and Adams (1991) that students are not able to develop critical thinking purely by interacting with the subject matter. A refinement of Instrumental Enrichment was proposed considering these principles.
Using ArcGIS Portal to inform decision making for Integrated Coastal Management, KwaZulu-Natal
Authors: Goble Bronwyn , Hill Trevor ,   University of KwaZulu-Natal, South Africa
Published: February 2021

The coastal environment is one of the most utilised for human activities; providing a diverse range of goods and services such as fisheries, water purification and coastal erosion protection. This results in the need for effective, ongoing management and informed decision making, to ensure long-term sustainability of the coastal environment. However, Goble et al. (2017) highlight that institutional knowledge and capacity are currently limited to achieve the objectives of effective coastal management. This research considers the use of ArcGIS Portal as a component of a Decision Support System (or Info-portal) for coastal management in KwaZulu-Natal, through the development of an online, interactive mapping platform. This platform offers a portal to decision makers to access and interrogate data and information, thus informing decision making. The development of this tool followed a participatory approach, and engagement with end-users throughout the process to ensure that the tool meets users’ requirements. To date, the info-portal has been well utilised by both decision makers and members of the public that are interested in the coast. It offers an excellent example of the power of a spatial tool in improving decision making.

Published: February 2021

Sanitation in school toilets is often considered peripheral to the academic project, yet has a significant impact on productivity and the school experience. A micro-study, pilot project to quantify the perception of odours in toilets at two schools in Gauteng Province, South Africa, using olfactory tests, reveals the presence of select odour-forming compounds. The compounds of butyric acid, indole, p-cresol and dimethyl trisulfide, reconstituted faecal odour and stale urine odour were presented to staff at the two schools in the form of ‘Sniffin’ Sticks’. All the odours were identified in the toilets at levels of unbearable in School A which has a septic tank system, and tolerable in School B which uses a flush system, during the pre-test. A post-test was conducted after an effective bioremediation treatment product was applied. We found that 100% of the participants noted a marked improvement in the odours in the toilets after the treatments were combined with efficient cleaning regimes.

Latihan di tempat kerja merupakan faktor kritikal dalam meningkatkan kekuatan sumber manusia khususnya pembentukan prestasi pekerja. Pengurusan sumber manusia yang optimis akan memastikan latihan tersebut memberi impak yang positif. Namun begitu, kebanyakan latihan yang dilaksanakan di kebanyakan organisasi sektor awam masih di tahap yang memuaskan. Justeru, kajian ini dijalankan bagi mengkaji pengaruh latihan bercirikan modul ketenteraan keatas pembangunan modal insan di Kementerian Pertahanan, Malaysia. Kaedah pengumpulan data daripada borang soal selidik yang diedarkan kepada 92 responden menggunakan formula Taro Yamanae. Prestasi pekerja berasaskan modul ketenteraan dianalisis berdasarkan analisis kebolehpercayaan, ujian kenormalan, analisis deskriptif, analisis kolerasi dan analisis regresi linear menggunakan Statistical Package for Social Sciences. Daripada ujian kenormalan, data Skewness dan Kurtosis bertabur secara normal yang menunjukkan nilai kepencongan berada dalam lingkungan 2.0 titik cut-off. Analisis deskriptif menunjukkan taburan kekerapan tahap prestasi pekerja pada tahap tertinggi bersamaan 90.32 peratus. Melalui analisis kolerasi, penggunaan modul ketenteraan mempunyai kolerasi yang tinggi. Analisis regresi linear turut menunjukkan terdapat hubungan yang signifikan antara modul ketenteraan terhadap prestasi pekerja khususnya dari aspek kerjasama sepasukan. Justeru, latihan berasaskan modul ketenteraan berupaya melatih mental dan fizikal pekerja awam khususnya mengurangkan tekanan bekerja dalam organisasi. Malah, perkembangan kognitif dan psikomotor pekerja amat bersesuaian dengan skop kerja dengan latihan tersebut. Pelaksanaan latihan bercirikan ketenteraan secara holistik telah memberi impak yang positif dalam pencapaian matlamat, misi dan visi organisasi sekali gus mengoptimumkan sumbangan modal insan memacu wawasan negara yang berjaya.

Published: February 2021

Artikel ini bertujuan untuk mengenal pasti tahap iklim organisasi sekolah dan tahap burnout guru serta hubungan iklim organisasi sekolah dengan burnout guru dalam kalangan guru sekolah menengah di daerah Subis, Sarawak. Kajian in adalah bersifat kuantitatif yang mendadaptasi dan menyesuaikan soal selidik Organisational Climate Index (OCI) dan Maslach Burnout Index (MBI) mengikut konteks kajian. Sampel kajian terdiri daripada 167 orang guru yang telah dipilih dengan menggunakan pensampelan rawak berstrata daripada 5 buah sekolah menengah di daerah Subis. Perisian SPSS versi 26 digunakan untuk menganalisis data dengan statistik deskriptif dan inferensi. Hasil kajian menunjukkan bahawa tahap iklim organisasi sekolah berada pada tahap yang sederhana (min= 2.58, SP=.379). Tahap burnout guru dalam kalangan guru sekolah menengah berada pada tahap sederhana rendah (min= 2.61, SP=.466). Analisis korelasi pearson yang menjelaskan hubungan iklim organisasi sekolah dengan burnout guru sekolah menengah daerah Subis pula mencatatkan korelasi yang tidak signifikan (r=.053) pada tahap sangat rendah. Analisis regresi berganda stepwise mendapati tiada dimensi iklim organisasi sekolah yang meramalkan tahap burnout [F (4, 162) = 0.689, p<0.05]. Dapatan daripada kajian ini menunjukkan bahawa iklim organisasi sekolah adalah kurang terbuka kerana pihak pentadbiran sekolah kurang memberi dan mendapat maklum balas daripada pihak ibu bapa dan pihak luar. Kajian lapangan perlu merangkumi aspek iklim sekolah yang lain seperti penglibatan murid, komitmen guru dan efikasi kendiri guru. Iklim organisasi sekolah yang rendah memberikan implikasi terhadap pengetua untuk meningkatkan akauntabiliti dan ketelusan kepada pihak ibu bapa serta bersikap terbuka untuk menerima pandangan daripada pihak lain.

Place branding management is one of the segments in destination branding, is a complex process of branding an entire country or a part of it. The Strategic Place Brand-Management model (SPBM-model by Hanna and Rowley, 2011) comprises of nine (9) dimensions which are argued to be important parts in the place branding process and research. This chapter aim to understand how place brand copes with the components in the SPBM-model, and to perceive which components in the SPBM-model that can be seen as the most important components based on a case study the perceptions of the city residents Kuala Terengganu, Malaysia. By positioning the Kuala Terengganu place branding process with the SPBM-model, it can be understood that all components are strongly connected to each other. Of all nine (9) components, three (3) of them which are evaluation, infrastructure and stakeholders should be given special attention if they are serious in branding Kuala Terengganu as one of the most attractive tourist destinations in the world.
Social Responses and Narrative Experiences of the Filipino Middle Class to the COVID-19 Crisis

Published: February 2021

The incessant spreading of COVID-19 disease has recently been the major concern to the Filipino since January 2020. The crisis becomes uncontrollable and impacts on all walks of life in terms of their routine living, working conditions, mental health, and social interaction. As observed in the past few months, the Philippine government has attempted to deal with the transmission of infection and economic predicament. However, there has been tremendous criticism towards the government’s methods of solving the problems, and one of the controversial discussions is the inequity of offering assistance packages to socio-economic groups. This article seeks to grasp the perceptions of the Filipino middle class who are mainly excluded by the aid of the government from the COVID-19 crisis since they are misrepresented as capable of self-help and self-responsibility in the neoliberal economy. The results evidently show their responses and narratives to the crisis through dealing with behavioural and social adaptation and psychological coping strategies. In times of the pandemic with low awareness of the government, most middle-class people are still precarious because of the entire dependency on the financial system and employment security to maintain subsistence in the present and future.
