Patterns of emotional and behavioural challenges in children living with HIV: results from a hyperendemic South African setting

ABSTRACT This study examined the patterns of emotional and behavioural problems in children from an HIV hyperendemic sub-Saharan Africa setting. A cross-sectional questionnaire survey was administered to 198 parents/caregivers of children living with HIV aged 2–12 years, attending a paediatric HIV out-patient service at a public sector hospital in KwaZulu-Natal Province, South Africa. The parent version of the Strengths and Difficulties Questionnaire (SDQ) which consists of five sub-scales (i.e. emotional difficulties, conduct problems, hyperactivity/inattention symptoms, peer problems and prosocial behaviours) were used to capture data on emotional and behavioural problems in children. The results indicated that over half of sampled children (n = 115, 58.1%) had abnormal levels of problems in at least one sub-scale, with adjusted regression indicating that academic difficulties and delayed milestones were significantly associated (i.e. greater total SDQ score as a continuous measure). Lower parental/caregiver educational attainment (i.e. not having tertiary education) was the only parent/caregiver characteristic associated with greater emotional and behavioural problems. Given the high prevalence of emotional and behavioural problems and its link to academic difficulties and delayed milestones, the need for screening and developmental support for children living with HIV may be warranted.
Relativistic Effects of Rotation in γ-ray Pulsars—Invited Review

In this paper, we consider the relativistic effects of rotation in the magnetospheres of γ-ray pulsars. The paper reviews the progress achieved in this field during the last three decades. For this purpose, we examine the direct centrifugal acceleration of particles and the corresponding limiting factors: the constraints due to the curvature radiation and the inverse Compton scattering of electrons against soft photons. Based on the obtained results, the generation of parametrically excited Langmuir waves and the corresponding Landau–Langmuir centrifugal drive are studied.
Dissolving the margins: LEANING INto an antiracist review process

In a thought-provoking ASEE Distinguished Lecture in June 2020, “Talking the Talk, Walking the Walk: What our Publications Say About Us as a Community of Scholars,” Dr. Lisa Benson challenged us from her vantage point as Editor-in-Chief of the Journal of Engineering Education (JEE) to consider who we are as a community and who has been doing the talking (Benson, 2020). We appreciated her perspective and reiterate two critical questions here. Specifically, if publications speak volumes, what messages are being spoken in our community of scholars? And further, if publications represent engineering education culture, what then is our culture, and what have we done to foster just experiences for all members of our academic community?
Effect of Iranian traditional cooking on fate of pesticides in white rice

Abstract In the current study, the reduction in the level of 42 pesticides from different chemical groups in white rice by means of traditional cooking was evaluated. A gas chromatography-mass spectrometry (GC/MS) system in combination with the modified QuEChERS technique as the base of sample preparation method was employed. The spiked rice samples (at 3 levels of 25, 100, and 500 ng/g) were analyzed to determine the reduction percentage of pesticide. Processing factor for each pesticide excepted for one of them was lower than 1. The introduced sample preparation and identification methods showed a precision as well as accuracy. The recovery of pesticides at three concentration levels was in the range of 84.08–105.95%. The highest and lowest percentages of pesticides reduction were reported as 99.8% and 15.6% for dichlorvos and metalaxyl, respectively. Regarding the different chemical groups, the most reduction is belong organophosphorus pesticides and the less reduction can be correlated to organochlorine pesticides. The results demonstrated that the Iranian traditional rice cooking, which involves long boiling times, significantly could reduce the concentrations of pesticide residues in white rice.
Emotional and behavioural problems of children with autism spectrum disorder attending mainstream schools

Emotional and behavioural problems occur more commonly in children with Autism Spectrum Disorder (ASD) compared to other children. Few studies have focused on these problems in children with ASD attending mainstream schools. We assessed via parent report the emotional and behavioural problems in 160 children aged 4-17 years with ASD attending mainstream schools and investigated differences between the primary and secondary aged children. Children with ASD had higher levels of problems across all domains of the Strengths and Difficulties Questionnaire (SDQ) compared to UK norms. Within the ASD sample, SDQ scores were associated with male sex, living in a household with more children, more severe autism symptoms and fewer adaptive skills, and higher levels of family socio-economic risk. No robust primary-secondary school differences were found. Implications for future research and the support of children with ASD in mainstream school settings are discussed.
FAKTOR YANG MEMPENGARUHI PENGGUNAAN SUMBER AIR MINUM LAYAK DI BENGKULU TAHUN 2018

Sumber air minum dan sanitasi layak merupakan komponen yang menjadi indikator baik buruknya lingkungan hidup. Air tidak dapat dipisahkan dari kehidupan manusia. Air menjadi kebutuhan dasar dan digunakan untuk minum, memasak, mencuci, mandi dan kegiatan lain yang bergantung pada air bersih sehingga air sangat penting bagi kehidupan manusia, bahkan makhluk hidup lainnya. Selain itu juga, sumber air dan sanitasi layak menjadi salah satu dari indikator utama dalam tujuan pembangunan berkelanjutan (SDGs) pada tujuan 6. Sumber air dapat berpengaruh terhadap perekonomian dan juga terhadap kesehatan. Semakin baik kualitas air yang digunakan, maka akan berpengaruh secara langsung terhadap baiknya kualitas kesehatan dan juga berpengaruh secara tidak langsung terhadap perekonomian. Provinsi Bengkulu merupakan provinsi dengan persentase sumber air layak terendah di Indonesia. Lebih dari setengah penduduknya menggunakan sumber air yang tidak layak dan hal tersebut jauh dari sasaran RPJMN yaitu 100 persen akses air minum layak pada tahun 2019. Sehingga penelitian ini bertujuan untuk menganalisis faktor yang mempengaruhi kelayakan sumber air minum yang digunakan di Bengkulu menggunakan metode regresi logistik biner. Dari hasil penelitian didapatkan bahwa faktor sosial ekonomi serta klasifikasi wilayah mempengaruhi penggunaan sumber air minum layak, sedangkan jumlah anggota rumah tangga dan faktor kelangkaan tidak berpengaruh.
The Effect of Si on CO2 Methanation over Ni-xSi/ZrO2 Catalysts at Low Temperature

A series of Ni-xSi/ZrO2 (x = 0, 0.1, 0.5, 1 wt%, the controlled contents of Si) catalysts with a controlled nickel content of 10 wt% were prepared by the co-impregnation method with ZrO2 as support and Si as a promoter. The effect of different amounts of Si on the catalytic performance was investigated for CO2 methanation with the stoichiometric H2/CO2 molar ratio (4/1). The catalysts were characterized by BET, XRF, H2-TPR, H2-TPD, H2-chemisorption, CO2-TPD, XRD, TEM, XPS, and TG-DSC. It was found that adding the appropriate amount of Si could improve the catalytic performance of Ni/ZrO2 catalyst at a low reaction temperature (250 °C). Among all the catalysts studied, the Ni-0.1Si/ZrO2 catalyst showed the highest catalytic activity, with H2 and CO2 conversion of 73.4% and 72.5%, respectively and the yield of CH4 was 72.2%. Meanwhile, the catalyst showed high stability and no deactivation within a 10 h test. Adding the appropriate amount of Si could enhance the interaction between Ni and ZrO2, and increase the Ni dispersion, the amounts of active sites including surface Ni0, oxygen vacancies, and strong basic sites on the catalyst surface. These might be the reasons for the high activity and selectivity of the Ni-0.1Si/ZrO2 catalyst.
Too Old to Forget: The Dynamics of Political Trust among Immigrants

Scholars have argued that immigrants’ trust in institutions is the result of the exposure to host-country institutions but also shaped by past experiences in the country of origin. These experiences create a “home-country point of reference,” a political/institutional memory that becomes the relevant comparison for any political/institutional interaction in the host country. We develop further this concept and unpack its key determinants—the age at migration and the historical conditions of the home country at the specific time of migration. Only those immigrants who were too old to forget the historical and contextual features of the country-of-origin institutions at the time of migration will rely on this comparison when interacting with institutions in the host country. Across time, there is both a continuous positive/negative accumulation of trust for the host-country institutions among those with less/more democratic points of reference. We examine immigrants’ political trust using survey evidence from Israel.
Gynecological Neoplasms are the Major Cause for Malignant Effusions

Background: Malignant effusions occur frequently in gynecologic neoplasms and may worsen the prognosis for these patients. Therefore a more detailed analysis for the different cavities is necessary to describe the association between the various histological subtypes and the time related occurrence of malignant effusions in gynecological malignancies. Methods: Malignant effusion specimens from patients diagnosed at Bayreuth Hospital from June 2013 to December 2018 were reevaluated retrospectively and correlated with the histolgogical subtype of primary tumors and with the clinical follow-up.Results: 435 patients with malignant effusions were analyzed, including 273 women and 162 men. 54.2% of patients developed malignant effusions in the pleural space in (54.2%) patients, in the peritoneum in (43.9%) patients and in the pericardium in (1.9%). Gynecological malignancies appear most common in (n=147, 34.0%; mean age 67.3 years) patients with predominant occurrence of ovarian carcinoma in malignant abdominal cytology in 75/191 (39.3%) patients, mostly of high-grade serous papillary subtype in 72/75 (96.1%), and only breast cancer in malignant pleural effusions in 49/236 (20.7%), frequently of 39/49 (79.6%) invasive carcinomas of no specific type. Both involvement of pleural- and peritoneal cavity in 244 female patients with gynecological-, lung- and gastrointestinal neoplasms we obtained in 37 (15.2%) patients, most common in 31/37 (83.78%) gynecological tumors and exclusively of high-grade serous papillary subtype. Malignant ascites occured in patients with lower genital tract tumors in 81/86 (94.2%) within one year after primary diagnosis, whereas breast cancer involves the peritoneum in 2/10 (20%) and the pleural cavity in 11/49 (22.4%) after 12 months. Conclusions: Gynecological neoplasms were the major cause of malignant effusions in our study. The high-grade serous papillary subtype of lower tract gynecological is most aggressive with predominant occurrence in the peritoneum and exclusive secondary involvement of the pleural cavity. Therefore, an alone/exclusive/sole involvement of the pleural cavity characterize the invasive breast carcinoma of no special type compared to predominant occurrence of the lobular subtype in malignant ascites. Breast cancer showed a statistical significant late occurrence in effusion fluids 12 months after primary diagnosis in contrast to early involvement in gynecological- as well as pulmonary- or gastrointestinal malignancies.
Experience perceptions, memorability and life satisfaction: a test and theory extension in the context of Oktoberfest

Based on the Oktoberfest context and memory-dominant logic (MDL), the purpose of the study included assessing drivers of the perceptions of experience uniqueness; if these drivers and experience uniqueness perceptions transformed in memorable experiences; and if memorable experiences translated into enhanced life satisfaction. Based on these relationships, a typology and theory extension is provided integrating practical examples. ,A five-factor model was tested using exploratory structural equation modeling and structural equation modeling; the factors included food and beverage quality; connectedness; experience uniqueness; meaningfulness and memorability; and life satisfaction. ,Guests connectedness impacted life satisfaction perceptions. Positive perceptions of the experience uniqueness resulted in higher memorability. Food and beverage quality impacted both memorability and life satisfaction. Higher memorability resulted in higher life satisfaction. Attendee nationality impacted the relationship among several of the study’s factors. ,Progress was made on assessing the MDL concepts and translating them into quantitative values. Study results supported the impact of connectedness and product quality on perceptions of Oktoberfest experience uniqueness along with the impact of meaningfulness of the experience on life satisfaction perceptions. The authors acknowledged limitations because of one Oktoberfest beer tent focus and the weaknesses of survey methodology, limiting pre- and post-activity reporting and future investigation of moderating effects. ,The consideration of higher order impacts (i.e. life satisfaction) is needed when delivering experiences and to entice loyalty and social media apostles. Consumers’ experience connectedness with high-quality perceptions and unique service design are likely to translate to memorable experiences, leading to life satisfaction perceptions. The concept of creating the experience “with” the customer appears to be a key aspect of memorability. ,These results tested aspects of MDL and a typology emerged of ideal types as a modified MDL framework driven by two continua: transactional vs experiential quality and experiences designed “to” vs “with” customers.
Coal Fly Ash–Clay Based Geopolymer-Incorporating Electric Arc Furnace Dust (EAFD): Leaching Behavior and Geochemical Modeling

The recent recovery processes of electric arc furnace dust (EAFD) include stabilization within materials with potential uses in the construction sector. The stabilization of EAFD by alkaline activation of different alumina-silicates, resulting in low-cost and environmentally friendly materials. The leaching standards within the different European regulations allow evaluating waste materials and products. This work aims to study the introduction of EAFD in FA–clay geopolymers, assessing the environmental and geochemical behavior in two different scenarios, disposal, and utilization. For it, the compliance equilibrium-based batch test (EN 12457-2) and pH dependence test (EN 14429) have been used. The dosages of EAFD in the geopolymeric matrix are 5% to 20% with curing temperatures of 75 °C and 225 °C. The introduction of EAFD favors the development of the flexural strength. From the environmental point of view, metals related to EAFD, such as Zn, Pb, or Cu, are retained in the matrix. While As or Se, comes mainly from clay, present a high concentration. Therefore, the role of clay should be analyzed in future research. As expected by the high iron content in the EAFD, the iron complexes on the surface of the material are responsible for immobilization of metals in this type of matrix.
Rewiring of interactions in a changing environment: nettle‐feeding butterflies and their parasitoids

is elevated at sites where Ar. levana has been established for a longer period. In our study system, variations in butterfly species assemblages were associated in a predictable way with substantial variations in rates of parasitism. This relationship is likely to affect the dynamics of the butterfly host species, and potentially cascade to the larger number of species with which they interact. These results highlight the importance of indirect interactions and their potential to reorganise ecological communities, especially in the context of shifts in species distributions in a warmer world.
Impact of a Brief Structured Psychoeducation Session on Antiepileptic Drug Adherence and Treatment Outcome in Persons with Epilepsy: A Prospective Cohort Study

Background: Poor adherence to antiepileptic drugs is one of the most important causes of treatment failure in persons with epilepsy (PWE). This study was aimed at assessing the impact of psychoeducation on drug adherence and treatment outcome in PWE. Methods: It was a prospective cohort study with a pre and posttest intervention design. A cohort of 100 epilepsy patients aged 18–65 years and on antiepileptic drugs for at least 6 months attending the outpatient department was enrolled in the study. Drug adherence was measured by Medication Adherence Rating Scale. A structured eight-domain epilepsy psychoeducation session with pictorial description was given to the study subjects in two parts (group and individually) lasting for a total of 30 min on the day of baseline assessment. Adherence and treatment outcome variables were assessed by an independent observer 4 months after the psychoeducation session. Chi-square test and paired t-test were used to analyze the data using SPSS version 20 with P value less than 0.05 considered as significant. Results: There was a statistically significant (P < 0.001) increase in the number of patients who were adherent to medications after psychoeducation session. There was a significant reduction in mean seizure frequency (0.68 ± 0.65) and seizure severity in terms of injuries sustained during seizure episodes post intervention. Regularities in the follow-up visits were also witnessed. A significant decrease in the number of hospital admissions (0.09 ± 0.32), mean inpatient treatment days (0.44 ± 2.19), and emergency room visits (0.19 ± 0.15) was noted 4 months after the psychoeducation session indicative of better treatment outcome. Conclusion: The present study proves the efficacy of a structured educational program in improving drug adherence and treatment outcome in a cohort of people with epilepsy.
Multi-modal MR imaging and magnetic hyperthermia study of Gd doped Fe3O4 nanoparticles for integrative cancer therapy

Among different kinds of cancer theranostic mediators, gadolinium (Gd) doped iron oxide nanoparticles are one of the most promising candidates in combining diagnostics (imaging) and therapeutics (molecular therapy) functions in a single, multimodal platform. Due to its larger size, the doping of Gd into the Fe3O4 is difficult. We have overcome this difficulty by modifying a polyol based reflux method that has been previously used for, for example, cobalt–zinc (Co–Zn) doping of ferrites but not for doping with Gd. This modified approach allowed a facile synthesis of Gd-doped superparamagnetic iron oxide (Fe3O4) nanoparticles (GdSPIONPs) with a lower Curie temperature (Tc) for hyperthermia superparamagnetism with low coercivity, both T1 and T2 based MRI contrast enhancements, low cytotoxicity and optimal hemocompatibility. Such a combination of theranostics properties in a single nanosystem is unprecedented and highly desirable for heat controlled magnetic hyperthermia in minimizing treatment resistance, and maximizing treatment efficacy.
Therapeutic Effects of Pembrolizumab Combined with Paclitaxel and Cisplatin Chemotherapy on Advanced Non-Squamous Non-Small Cell Lung Cancer and Influencing Factors

To explore the therapeutic effects of pembrolizumab combined with paclitaxel and cisplatin chemotherapy on advanced non-squamous non-small cell lung cancer and its influencing factors is the main objective. A total of 87 patients with advanced non-squamous non-small cell lung cancer treated in our hospital from October 2016 to May 2018 were enrolled and allocated into control group and observation group according to their disease conditions and willingness. Paclitaxel and cisplatin chemotherapy regimen was employed for control group, based on which pembrolizumab was used for observation group. Cellular immunity indices, cytokine indices, short-term efficacy, adverse reactions, and long-term prognosis were compared, and the factors affecting short-term efficacy and long-term prognosis were analyzed. After treatment, observation group exhibited increased cluster of differentiation 3+ T lymphocytes, cluster of differentiation 4+ T lymphocytes, and cluster of differentiation 4+/cluster of differentiation 8+ ratio and decreased cluster of differentiation 8+ T lymphocytes compared with control group (p 0.05). Decreased cluster of differentiation 4+/cluster of differentiation 8+ ratio increased tumor necrosis factor-alpha level and chemotherapy were risk factors for the poor short-term efficacy and long-term prognosis in patients with advanced non-squamous nonsmall cell lung cancer (p<0.05), and clinical stage IV was a risk factor for the unfavorable long-term prognosis as well (p<0.05). Pembrolizumab combined with paclitaxel and cisplatin chemotherapy regimen can relieve the cellular immune suppression and alleviate inflammatory responses to improve the shortterm efficacy and long-term prognosis, without raising the incidence rate of severe adverse reactions in the treatment of advanced non-squamous non-small cell lung cancer
Discussion on Some Problems of Bridge Scour in Both Experiment and Simulation

The scour of bridge piers is one of the important factors causing bridge damage. The research on the scour mechanism of bridge pier includes two main ways: physical experiment and numerical simulation. In this paper, the research progress in recent decades is summarized, and the influencing factors that include the Reynolds number, pier shape in physical experiments and the selection of models such as RANS, LES, DES in numerical simulation are sorted out. Both physical experiment and numerical simulation are used to investigate the depth of scour hole and flow structures. Finally, it is pointed out that the stress characteristics generated by scouring flow are one of the directions for further research.
Carotenoid profile and functional properties of flour blends from biofortified maize and improved soybean varieties for product developments

Abstract Biofortified maize has received increased attention from a nutraceutical perspective because of its bioactive phytochemical components, including carotenoids. However, biofortified maize is limiting in some amino acids which are present in soybeans; hence both crops are used as blends in food products. Thus, this study aimed to evaluate the carotenoids and functional properties of maize-soybean flour blends as influenced by biofortified maize variety. Flour blends were prepared from each maize flour by substituting with 0–30% soybean flour. The flour samples were analysed for the carotenoid profile, proximate composition, colour, functional and pasting profile using standard methods. Carotenoids varied between the biofortified maize flours with xanthophylls (10.93–12.61 µg/g) being the most abundant, especially zeaxanthin (6.31–6.75 µg/g). Biofortified maize-soybean flour blends had lower carotenoid profiles with lower pro-vitamin A (3.79–6.99 µg/g) and xanthophylls (2.94–10.59 µg/g). The blends had higher protein, fat and ash contents with lower crude fibre and total carbohydrate than 100% biofortified maize flours. The blends also had lower bulk density, dispersibility, swelling power and pasting viscosities but increased solubility for both maize varieties. Maize flour from Sammaz 39 variety had higher pasting viscosities than Sammaz 40 variety. Trough, setback and final viscosities of maize-soybean flour blends made with S39 maize variety indicate pasting properties that will produce desirable properties in food products. The results showed that the blends could provide the raw material for the production of food products with improved carotenoid and protein contents as well as desirable functional qualities.
