Whiteness in the COVID-19 Pandemic: Who is Talking About Racism With Their Kids?

The present study investigated factors associated with parent awareness and socialization surrounding COVID-19-related racial disparities among White parents of children ages 1.5–8 living in Canada and the United States (N = 423, 88% mothers). Participants responded to an online survey about parenting during the pandemic between mid to late-April 2020. Participants reported on their level of awareness of COVID-19-related racial disparities as well as how often they discussed these with their children. Although 52% reported some level of awareness, only 34% reported any amount of discussion with their child about it. Regression models were used to further examine stress-related, socioeconomic, parenting, and news-watching associations with awareness and socialization. This study provides unique insight into which White parents are aware of racial inequities exposed by the pandemic and which are choosing to speak to their children about them. Current summary recommendations for White racial socialization and related research are also presented.

The effect of psychological capital and leader-member exchange on job crafting and organizational synergy: The case of a public hospital

Psychological capital is of great importance for organizations to gain sustainable competitive advantage and reach organizational goals through the effective use of human resources. The theory of leader-member exchange focuses on the main characteristic of the relationships between the leader and the employees, ensures that these relationships occur at different levels with each employee, and affect several behaviours of the organization, particularly performance. The most critical behavioural outcomes of the psychological capital and leader-member exchange concepts are organizational synergy and job crafting. For healthcare professionals with busy and stressful working hours, their psychological capital would strengthen motivation through the leader-member exchange, thus, supporting job crafting and organizational synergy. This study aims to reveal the effect of psychological capital and leader-member exchange on job crafting and organizational synergy in healthcare personnel through structural equation modelling. As a result of the analyses, it was determined that psychological capital and leader-member exchange were significantly and positively related to job crafting and organizational synergy, and psychological capital was a more vital influencer than leader-member exchange. It is expected that this study will raise awareness among managers and decision-makers working in the healthcare sector, serve as a guide, and also create an input for future studies.
Testing the structural validity of the model designed for perceived ease of use, perceived usefulness, trust, and intention to use Bitcoin with process macro

The first cryptocurrency, Bitcoin, has recently received much attention from researchers. There are studies by researchers to contribute more to the Bitcoin literature. However, it is essential to support the Bitcoin literature with different studies. While testing the structural validity of an integrated model that extends the technology acceptance model with a trust structure, this study aims to explain users' intention to use Bitcoin based on their perception of Bitcoin as accessible and valuable and their trust in Bitcoin. Data were collected from 206 participants using an online survey for this aim. The structural validity of the model, which was tested with the macro process technique, was confirmed by statistical analysis. According to the statistical analysis results, the perceived ease of use of Bitcoin, perceived usefulness of Bitcoin, and trust in Bitcoin and the existing relationships between these factors are practical on the intention to use Bitcoin. However, it should be noted that users' intentions to use Bitcoin do not differ significantly in terms of gender, age-range/generation, education status, and monthly income. This study provides implications for both theory and practice and recommendations for future research.
Anatomical, Histological and Radiological Studies of Parotid Salivary Glands of the Red Fox (Vulpes vulpes) with Comparison to Baladi Dog

The present study was designed to investigate and compare the gross anatomy and histology of the parotid glands, with details of their ducts and radicals, in dogs and foxes, using contrast radiographs. It was applied on six heads for each apparently healthy, adult Baladi dog and red fox that was euthanatized by pentobarbital. All parotid salivary glands were dissected for morphological investigations. Two specimens were injected through the parotid papilla by colored latex neoprene to show the intra glandular distribution of the parotid duct and the other one was inoculated by Urographin for lateral radiograph. The parotid salivary gland appeared as a thin, unevenly triangular shaped gland, located ventrally to the base of the ear. Dorsal border of the gland was notched in the dog but not in the red fox. The parotid radicals had four main branches in the dog, while three major radicals were seen in red fox. Portions of the right and left lobes of parotid salivary glands from other three heads for each dog and fox were fixed in 10% neutral buffered formalin for histological and histochemical investigation. The parotid gland of the dog consisted of pure serous acini, while it consisted of both serous and mucous secretory units in the fox. The acinar cells in the dog revealed a weak positive reaction to the Alcian blue stain. On the contrary, acinar cells in the fox were particularly mucous adenomeres, displaying a significantly high positive reaction. Both secretory acinar cells and duct system lining cells in the dog and fox parotid gland showed weak positive reaction to Periodic Acid-Schiff stain. This work gave a detailed description of parotid salivary gland to help veterinarians in clinical diagnosis and surgical approach.
Sentinel 1A SAR Backscattering Signature of Maize and Cotton Crops

Crop discrimination is a key issue for agricultural monitoring using remote sensing techniques. Synthetic Aperture Radar (SAR) data are advantageous for crop monitoring and classification because of their all-weather imaging capabilities. The multi-temporal Sentinel 1A SAR data was acquired from 08th August, 2015 to 23rd January, 2016 at 12 days interval covering the extent of Perambalur district of Tamil Nadu. Both the Vertical Vertical (VV) and Vertical-Horizontal (VH) polarized data are compared. The ground truth data collection was performed for cotton and maize during the vegetative, flowering and harvesting stages. The temporal backscattering coefficient (σ0) for cotton and maize are extracted using the training datasets. The mean backscattering values for cotton during the entire cropping period ranges from -10.58 dB to -6.28 dB and -20.59 dB to -14.53 dB for VV and VH polarized data respectively, and for maize it ranges from -11.08 dB to -7.07 dB and -19.85 dB to -14.14 dB for VV and VH polarized data respectively.
International Journal of Instruction

Self-Regulated Learning (SRL) is important to solve learning problems. This research aimed to determine the effect of the problem-solving based SelfRegulated Learning (SRL) strategy on simple harmonic motion material toward the metacognitive abilities of student’s senior high school. This research applied a quasi-experimental method with a pre-test and post-test control group design. This research was conducted at Senior high school (SMAN 5 Yogyakarta) with student (n=216). This research used a quasi-experimental method with pre-test-post-test control group design. Sampling was carried out by purposive sampling technique. The instrument used was a test in the form of an essay question sheet and a nontest in the form of a self-regulation journal and student observation sheets. Based on the results of the research, the results of the post-test data hypothesis test for the experimental class and the control class obtained that the calculated Z value was greater than the Z table value (-3.677>-1.96) and the significance value (2-tailed) was 0.001 or less than 0.05. Therefore, the problem-solving based Self-Regulated Learning strategy affected the metacognitive ability of students. Metacognition ability was known on each self-regulation indicator as evidenced by the description of students' answers. It could be found from the N-gain average score, 0.5904, categorized as “moderate”. The learners’ metacognitive skills were found on each indicator of self-regulation, proven with the descriptions of learners’ answers. This learning strategy could be applied as a solution to reflect the learning and learners’ cognitive activities in solving physics problems.
Measurement of the TCMB evolution from the Sunyaev-Zel’dovich effect

In the standard hot cosmological model, the black-body temperature of the cosmic microwave background (CMB), TCMB, increases linearly with redshift. Across the line of sight CMB photons interact with the hot (∼107−8 K ) and diffuse gas of electrons from galaxy clusters. This interaction leads to the well-known thermal Sunyaev-Zel’dovich effect (tSZ), which produces a distortion of the black-body emission law, depending on TCMB. Using tSZ data from the Planck satellite, it is possible to constrain TCMB below z = 1. Focusing on the redshift dependance of TCMB, we obtain TCMB(z) = (2.726 ± 0.001) × (1 + z)1−β K with β = 0.009 ± 0.017, which improves on previous constraints. Combined with measurements of molecular species absorptions, we derive β = 0.006 ± 0.013. These constraints are consistent with the standard (i.e. adiabatic, β = 0) Big-Bang model.
A Preliminary Study on Using Smartphones to Detect Falling Accidents

—In order to improve the disadvantages of current smartphone-based fall detection systems, this paper analyzes the characteristics of triaxial accelerometer values to identify thresholds of the non-falls and falls, and proposes an improved threshold-based fall detection method, which is not only able to quickly filter out most of daily activities (including walking running, sitting down, and so on) but also to detect the direction of four types of falling events. Moreover, as soon as a falling accident is detected, the user’s position could be immediately sent to the rescue center so as to get medical help.
Kinetic Aspects of the Interactions between TiO2 Nanoparticles, Mercury and the Green Alga Chlamydomonas reinhardtii

Aquatic organisms are exposed to mixtures of environmental pollutants, including engineered nanoparticles; however, the interactions underlying cocktails’ effects are poorly understood, in particular, the kinetic aspects. The present study explored the time course of the interactions between nano-sized titanium dioxide (nTiO2) with different primary particle sizes, algae and inorganic mercury (Hg) over 96 h under conditions that were representative of a highly contaminated environment. The results showed that nTiO2 with smaller primary particle size and higher concentrations rapidly reduced the adsorption and internalization of mercury by green alga Chlamydomonas reinhardtii. Such a mitigating effect on mercury bioavailability could be explained by the strong adsorbing capacity of nTiO2 for Hg and the aggregation and sedimentation of nTiO2 and bound Hg. The present study highlighted the key processes determining the bioavailability of mercury to the algae in mixture exposure under conditions representative of a highly contaminated environment, such as industrial wastewater effluents.

Effect of Dose Escalation on the In Vivo Oral Absorption and Disposition of Glycylsarcosine in Wild-Type and Pept1 Knockout Mice

This study evaluated the in vivo absorption and disposition of glycylsarcosine (GlySar), after escalating oral doses, in wild-type and Pept1 knockout mice. [ 3 H]GlySar was administered to mice at doses of 1, 10, 100, 1000, and 5000 nmol/g body weight. Serial blood samples were obtained over 480 min, the plasma harvested, and area under the plasma concentration-time curve (AUC) determined. It was observed that the GlySar AUC was 60, 45 and 30% lower in knockout than wild-type mice when evaluated over 2, 4 and 8 hr, respectively (p < 0.01). Plasma levels of GlySar reached a plateau at 90 min in knockout mice and then rose to a second plateau at 240 min. In wild-type mice, the plasma levels rose continuously to reach a single plateau at 90 min. When partial AUC (0-120 min) was used as an indicator for rate of absorption, there was a 60% reduction in GlySar absorption rate in knockout mice compared to wild-type animals. Tissue distribution studies were also performed after 10 nmol/g oral doses of [ 3 H]GlySar. When sampled 1 hr after dosing, GlySar tissue concentrations were significantly lower in knockout versus wild-type mice and, with the exception of intestines, reflected differences in the systemic exposure of dipeptide between these two genotypes. Overall, PEPT1 ablation in mice resulted in significant reductions, in vivo, in the rate and extent of GlySar absorption. The AUC of GlySar was dose-proportional in both genotypes over 1-100 nmol/g, with minor decrements at the two highest doses.
Australian engineering educators’ attitudes towards Aboriginal cultures and perspectives

ABSTRACT In Australia, representation of Aboriginal populations within the engineering profession is very low despite participation targets set by Government departments, professional bodies and Universities. Progressing the Aboriginal inclusion agenda within Australian Engineering Education requires a clearer understanding of engineering educators’ preparedness for increased numbers of students from this non-traditional cohort. This research stems from a recently completed project that explored Aboriginal perspectives in engineering education and proposed a model for embedding perspectives in curricula. Nine engineering academics were interviewed to explore attitudes towards Aboriginal perspectives in engineering and the viability of the proposed model. Results of the interviews indicate efforts to embed Aboriginal perspectives are starting from a small base of knowledge and experience. Individuals’ motivations and values indicate that there is significant support for improving this, but that efforts can be hampered by conceptions of Aboriginal perspectives that do not consider how Aboriginal knowledges may change engineering itself.
EARNING MANAGEMENT: THE MODERATING EFFECT OF CORPORATE GOVERNANCE AND THE EFFECT MANAGEMENT OVERCONFIDENCE

Many studies have discussed the determinants of earning management. However, most of these studies discuss external factors of management such as audit quality and quality of disclosure and as a determinant of earning management. Study that tries to examine the intrinsic factors such as managerial overconfidence effect on earning management has not been widely conducted, especially in companies listed on IDX, Indonesia. The present study aims to examine the effect of managerial overconfidence on earning management in companies listed on IDX. Furthermore, this study also aims to examine the corporate governance mechanisms as moderator variable on the relationship between managerial overconfidence and earning management. By using data analysis with the SEMPLS technique, the present study has succeeded to prove that managerial overconfidence affects earning management. Furthermore, this study also successfully provide evidence that corporate governance mechanisms such as independent audit committees and audit committee activities moderate the relationship between managerial overconfidence and earning
Verification of pillar life prediction method

The principal goal of the research descriptionbed in the paper was to determine, by measurement of pillar scaling on pillars that have not failed, whether the pillar life prediction method developed by van der Merwe (2003) was valid as it stood or whether adjustments were necessary to the rates indirectly derived from observation of failed pillars. To this end, measurements were taken on over 350 pillars at 13 sites on 6 mines. The project was done as a collaborative effort between the University of Pretoria, the Nancy School of Mines and CSIR Miningtek. During the course of the investigation, it was found that the majority of pillars display maximum scaling at mid height, that there was no clear preferential direction of pillar scaling, and that pillar corners do not scale significantly more than the mid pillar areas. The most important conclusion was that the scaling rates found by measurement agreed with the inferred rates found in the previous work. The previously developed procedure for the prediction of pillar life spans consequently requires no adjustment, although the error span is in the region of 20%. It is recommended to do further research into the effect of sealing of panels and, possible chemical changes taking place in the pillars as they age on the scaling rate.
Metabolism of Gambogic Acid in Rats: a Rare Intestinal Metabolic Pathway Responsible for its Final Disposition

: Gambogic acid (GA) is a promising natural anticancer candidate. Although the anticancer activity of GA has been well demonstrated, information regarding the metabolic fate of GA is limited. Previous studies suggest that GA is mainly excreted into intestinal tract in rats through bile after i.v. administration, whereas only traces appeared in the feces, suggesting that GA is metabolized abundantly in the intestine. However, there is no report about the intestinal metabolism of GA either in animals or humans. In this study, two sulfonic acid metabolites of GA were found abundantly in the fecal samples of rats after i.v. administration and their structures were identified as 10- α sulfonic acid GA and 10- β sulfonic acid GA by comparison of the retention time and spectral data with those of synthesized reference substances using LC-DAD-MS/MS. This rare intestinal metabolic pathway mainly involves Michael addition of sulfite ion to the 9, 10 carbon-carbon double bond of α , β -unsaturated ketone. Additionally, a more detailed metabolic profile in rats is proposed according to the results of in vitro and in vivo studies. It is found that GA can be metabolized by a variety of routes, including mono-oxidation, hydration, glutathionylation, glucuronidation, glucosidation in the liver of rats. These findings provide information on the major metabolic soft spot of GA in the intestine and liver of rats, which is not only useful in the future human metabolic study of this compound, but also of value in the metabolic studies of GA analogues.

The Effects of Stem Cells on Multiple Myeloma

Multiple myeloma is the second most common hematological disease characterized by uncontrollable cell proliferation of malignant plasma cells in the bone marrow. Evolution of multiple myeloma stems from asymptomatic precursor states of multiple gammopathy of undetermined significance or smoldering multiple myeloma. Standard care of newly diagnosed multiple myeloma patients includes various induction therapies of different combinations of corticosteroids, proteosome inhibitors, and immunomodulatory drugs. Stem cell transplantation into the bone marrow of myeloma patients is a regenerative therapy that possesses the capability of restoring functionality in non-functional cells. Hematopoietic stem cells and mesenchymal stem cells have shown promise in restoring functionality to non-functional cells. Clinical trials of hematopoietic stem cells and preclinical animal models have exhibited success of stem cell transplantation as a regenerative therapy for multiple myeloma.
