Reflecting on a Multi-Perspective Approach to Teaching and Learning about Police Shootings

This reflective essay highlights the importance of project structure when teaching highly controversial topics. I review research that shows differing approaches to teaching highly controversial subjects and the impact of the approaches on learning outcomes. I then reflect on the outcomes of deploying a non-directive, peacekeeping approach to address the issue of police-involved shootings in a criminal justice class. Finally, I draw attention to ancillary issues that emerge in this project structure as well as how the results impacted my own thinking about this topic.
Mindfulness and Work Engagement: An Examination of Mediating Mechanism and Boundary Condition

This study takes employees of enterprises and institutions as the research sample, exploring the mechanism and boundary condition of mindfulness on work engagement with questionnaire survey. Specifically, our study focuses on the direct influence of mindfulness on employees' work engagement, the mediating effect of ego-depletion in the influence of mindfulness on employees’ work engagement and the moderating effect of depletion sensitivity in the influence of ego-depletion on work engagement. The final results confirm that: a) Mindfulness has positive impact on work engagement; b) Ego-depletion mediates the influence of mindfulness on work engagement; c) Depletion sensitivity moderates the influence of ego-depletion on work engagement, which means the higher level of depletion sensitivity is associated with the stronger negative impact of ego-depletion on work engagement.
Genotoxicity of plant mediated synthesis of copper nanoparticles evaluated using in vitro mammalian cell micronucleus test

Objective: Nanotechnology is an emerging technology which has wide applications in many fields. Prime concern of research in nanotechnology is the synthesis of nano-material with the controlled size and shape. Recently, biosynthesis of metallic nano-particles has gained popularity owing to its eco-friendliness. The increasing use of copper nanoparticles (CNPs) in medicine and industry demands an understanding of their potential toxicities. Methods: Genotoxicity of CNPs was assessed using the in vitro micronucleus assay which is standard genotoxicity assay. In this study, CNP was tested in the absence and presence of the metabolic activation (2% v/v S9 mix). Human peripheral blood lymphocyte cultures were exposed to CNPs, at 5 dose-levels between 0.125 to 2μL/mL of culture medium in absence and presence of the metabolic activation system. Results: Required level of cytotoxicity (55 ± 5% reduction in replicative index, i.e., cytostasis) was observed in absence of the metabolic activation at the test concentration of 2 μL/mL. Therefore, dose levels selected for scoring of binucleated cells containing micronuclei were: 0.5, 1, and 2 μL/mL. From the obtained data of MNBN cells (Binucleated cells with micronuclei) for all three selected test concentration was found in the range of negative and vehicle control. Conclusion: Our results concluded that, CNPs did not induce statistically significant or biologically relevant increase in number of binucleated cells with micronuclei in absence and presence of the metabolic activation.
The COVID-19 Pandemic and Its Effect on the Mental Health of Doctors in India

Background and Objectives: For doctors at the forefront of the COVID-19 pandemic, failure to acknowledge and act on the warning signs of stress can adversely affect their professional, social and personal life. We conducted a nationwide survey of a large sample of Indian doctors to measure levels of perceived stress, identify risk factors for severe stress and assess their response to current issues related to the safety and well-being of the community. Methods: An online survey using Google forms was conducted between 1st May 2020 and 15th May 2020. The core component of the survey was the standardized Perceived Stress Scale answered on a Likert scale. Results: Out of 520 responders, 394 (76%) were under 45 years of age 101 (19%) were between Original Research Article Nair et al.; AJMAH, 18(11): 55-70, 2020; Article no.AJMAH. 63049 56 18-30 years and 37 (7%) were above 60 years. 312(60%) were male doctors and 203 (40%) were female doctors. 90% of respondents had a post-graduate degree, 48(9%) had undergraduate degree and 168(32%) had super specialty degree. 313 (60.2%) of the respondents were practising in the private sector, 169 (33%) worked in public sector hospitals and 32(7%) in charitable hospitals. 109 (21%) had low stress, while 371 (71%) and 40 (8%) reported moderate and severe stress respectively. Multivariate analysis revealed the female gender, being financially insecure and ICU a place of work as independent risk factors for severe stress. Conclusion: This is the first such survey done in the context of the COVID-19 pandemic from the Indian sub-continent and has identified factors that have the potential to adversely impact the mental health of doctors. These findings are applicable to many countries in Asia and Africa with similar healthcare systems and can act as a valuable guide for authorities to establish support systems at multiple levels for these “COVID Warriors”.
Predicción del Trolling desde el sadismo y la adicción a Internet en jóvenes adultos de Buenos Aires

Background: Trolling is a very topical phenomenon, but much less studied unlike other problems related to new technologies. The present study evaluated the levels of trolling in adults from sadism and internet addiction. Method: For this purpose, an intentional sample of 708 adults of both genders (56% women, age M = 25 years SD = 8.7), from the Autonomous City of Buenos Aires (CABA) and Greater Buenos Aires (GBA), Argentina is selected. Participants answered the Trolling Questionnaire by Buckels et al., On Sadistic Tendencies by Paulhus et al., On Internet Addiction by Lam-Figueroa et al. and a demographic questionnaire. The data indicated that both vicarious sadism, outright sadism, and dysfunctionality in Internet use were predictors of trolling. Results: The results suggested an association of trolling with age and differences according to gender. A structural model to predict trolling based on sadism as a latent variable and internet addiction shows an adequate fit CFI = . 99, TLI = . 98, RMSEA = . 04, indicating that sadism predicted trolling and internet addiction. Conclusion: Sadism is an important predictor for trolling behavior over the internet, where individuals with these characteristics take advantage of anonymity to carry out their aggressive behaviors.
Association between Serum Levels of Vitamin D, Vitamin B12 and Folate with Oxidative Biomarkers in Diabetic Type 2 Patients in People in Erbil City: A Case-Control Study

Background: Diabetes mellitus is the largest endocrine disorder in the world that refers to chronic hyperglycemia caused by impairment in both insulin secretion and action. Folate, vitamin B12, and vitamin D deficiency are related to the prevalence of type 2 diabetes mellitus. Objective: This study has been carried out to investigate the role of folate, vitamins B12, and D status during the progression of diabetic type 2 patients compared to non-diabetic control subjects. Patients and Methods: We measured the plasma levels of folate, vitamins B12, and D, along with blood glucose, HbA1c, and oxidative biomarkers in 50 diabetic type 2 patients and 50 healthy subjects used as a control group. Results: The findings revealed that the serum level of malondialdehyde (MDA) significantly increased in diabetic patients compared to healthy subjects, and the serum level of nitric oxide (NO) in T2D patients lower than in control. The concentration of vitamin D, B12, and folate in T2D patients significantly lower than non-T2D control. The results also showed a significant relationship between serum vitamin D, MDA, and NO with HbA1c, while there was an insignificant correlation between vitamin B12 and folate with HbA1c. Conclusion: The oxidative biomarkers and vitamins D, B12, and folate level can play an important role in the development and progression of T2D.
Cyanoacrylate Tissue Adhesive as a Membrane in Socket Preservation: In Vitro Cytotoxicity and Clinical Evaluation

Background: Cyanoacrylate-based adhesives provide immediate hemostasis when applied; this is attributed to their ability to form a mechanical barrier in the surgical site, favoring the coagulation process and allowing control of bleeding. The purpose of the present study was to demonstrate the in vitro effect of cyanoacrylate-based tissue adhesive and the clinical evaluation of wound healing of freshly extracted sockets with adhesives applied on an exposed collagen membrane, for preservation of the alveolar ridge. Methods: Cytotoxicity was evaluated with sulphoradamine B assay with primary fibroblasts from gingival tissue. The in vivo analysis was carried out in 10 patients needing extraction of single-rooted teeth, who met the inclusion and exclusion criteria and signed the term of free and informed consent. Alveolar preservation was carried out with a mineralized cortical allograft bone substitute and a resorbable collagen membrane that was intentionally left exposed. On the exposed membrane, the Periacryl® 90 HV was applied as a barrier. The biocompatibility of the adhesive was assessed by the Early-Wound Healing Index (EHI) and Early Wound Healing Score (EHS), of perialveolar tissues at time intervals of 12, 30- and 60-days post-surgery. Results: Reduced cell viability was observed for Periacryl® 90 HV when compared with cells without adhesive treatments. No postoperative complications were observed after the application of Periacryl® 90 HV on perialveolar tissues. Conclusion: The use of the Periacryl® 90 HV cyanoacrylate-based tissue adhesive resulted in reduced fibroblast viability in vitro, and adequate results of wound closure in the clinical evaluation of EHI and EHS scores.

Hepatitis B virus (HBV) infection is a major public health problem worldwide especially for healthcare professionals (HCPs). It is a potentially life-threatening condition because leads to liver infection, and liver cancer. There is a shortage of research on undergraduate students. The main aim of this study was conducted to assess the level of knowledge of health care professionals regarding HBV at Rania hospitals in the Kurdistan region of Iraq during the period of 20th October 2019 to 16th April 2020. Non- probability purposive sample of (303) HCPs; for data collection, the study instrument was constructed and designed through reading literature, books, and articles which included (42) items. Reliability of the instrument was determined through the use of stability reliability (test and retest) approach which was estimated as r = (0.83.)The data were collected through the use of the interview technique then organized and coded into computer files. Statistical approaches were uses for data analysis, which includes: descriptive and inferential statistics and chi-square, data analysis (SPSS version 25). The results indicated that the majority of the study samples were in the age group (≤ 30)) years and the female participants was more than male, three-quarters of the participants were married, most of them were graduated from institute nursing and less than half of HCPs had 6-10 years of employment, but the majority of the participants were not trained at all, and most of them had not immunized against HBV vaccine. Three-quarters of HCPs had moderate knowledge regarding HBV infection. Also, the current study demonstrated a significant association between the educational level and HCP's knowledge regarding HBV, at a P value less than 0.05. on site other hand, there was no significant association between HCP's age, gender, marital status, years of employment, and training course concerning hepatitis with the level of knowledge regarding HBV. The researchers recommended to the ministry of health and directorate of health in Rania city to complete vaccinate against HBV for all HCPs and participating their staff in healthy scientific issues and symposiums.

Kinetic parameters of Lactobacillus plantarum and Saccharomyces boulardii growing in a beet molasses culture media

Regular consumption of probiotic microorganisms as part of the diet can contribute to improving health and mitigating the effects of metabolic syndrome diseases. Then, it is essential to design production processes for this type of microorganisms, which are optimal from the point of view of production time and cost. This paper presents a study of the effect of using a low-cost culture medium, formulated with beet molasses, which manages to enhance the growth of two types of probiotic microorganisms, Saccharomyces boulardii, and Lactobacillus plantarum. In addition to its effect on cellular biomass growth, a kinetic model for both strains growth is also presented. This model includes factors such as the S. boulardii capability to hydrolyze saccharose into their respective monosaccharides and the inhibition effect of lactic acid production on L. plantarum growth. Finally, a mixed culture production scheme is proposed for both microorganisms, in order to take advantage of the yeast's capability to hydrolyze saccharose, in order not to require the addition of extra glucose to the culture medium.
The Correlation Between Self-Esteem and Body Image: A Study on Female Adolescent Instagram Users

The overall affective evaluation of one's own worth, value, or importance, as known as Self-esteem (Blascovich & Tomaka, 1991), is constructed by various aspects of self-evaluation, and physical appearance is one of these aspects. Individual body image, how a person perceives his or her body and how satisfied he or she is about it (Grogan, 2016) is likely linked with their self-esteem especially in adolescence which is a period of time when body image concern in young women is at its peak (Burgess et al., in Grogan, 2016). Social media usage, particularly Instagram which is a picture based social media may affect the users’ perceptions about their body due to comparison that possibly happen. The aim of this research is to identify whether self-esteem is linked with body image in female teenager Instagram users. The research involved 150 female teenagers who were using Instagram recently by using snowball sampling technique. The method that was used in this research is a non-experimental quantitative method. There were two instruments used in the research. Self-esteem was measured by State Self-Esteem Scale and body image was measured by Multidimensional Body-Self Relations Questionnaire-Appearance Scale. The result showed that there is correlation between self-esteem and body image in female teenager Instagram users, meaning that the research hypothesis is accepted. Furthermore, it was shown that Appearance Evaluation is the body image dimension with highest correlation with self-esteem (r=0.713).
Covariation of Airborne Biogenic Tracers (CO2, COS, and CO) Supports Stronger Than Expected Growing Season Photosynthetic Uptake in the Southeastern US

The Atmospheric Carbon Transport (ACT)‐America Earth Venture mission conducted five airborne campaigns across four seasons from 2016 to 2019, to study the transport and fluxes of Greenhouse gases across the eastern United States. Unprecedented spatial sampling of atmospheric tracers (CO2, carbon monoxide [CO], carbonyl sulfide [COS]) related to biospheric processes offers opportunities to improve our qualitative and quantitative understanding of seasonal and spatial patterns of biospheric carbon uptake. Here, we examine co‐variation of boundary layer enhancements of CO2, CO, and COS across three diverse regions: the crop‐dominated Midwest, evergreen‐dominated South, and deciduous broadleaf‐dominated Northeast. To understand the biogeochemical processes controlling these tracers, we compare the observed co‐variation to simulated co‐variation resulting from model‐ and satellite‐ constrained surface carbon fluxes. We found indication of a common terrestrial biogenic sink of CO2 and COS and secondary production of CO from biogenic sources in summer throughout the eastern US, driven by stomatal conductance. Upper Midwest crops drive Δ CO2 and Δ COS depletion from early to late summer. Northeastern temperate forests drive Δ CO2 and Δ COS depletion in late summer. The unprecedented ACT‐America flask samples uncovered evidence that southern humid temperate forests photosynthesize and absorb CO2 and COS, and emit CO precursors, deep into the growing season. Satellite‐ constrained carbon fluxes capture much of the observed seasonal and spatial variability, but underestimate the magnitude of net CO2 and COS depletion in the South, indicating a stronger than expected net sink of CO2 in late summer. Additional sampling of the South will more accurately constrain underlying biological processes and climate sensitivities governing southern carbon dynamics.
A Stacked Auto-Encoder Based Partial Adversarial Domain Adaptation Model for Intelligent Fault Diagnosis of Rotating Machines

Fault diagnosis plays an indispensable role in prognostics and health management of rotating machines. In recent years, intelligent fault diagnosis methods based on domain adaptation technology have attracted the attention of researchers. However, a more extensive application scenario of fault diagnosis − partial domain adaptation (PDA) − has not been well-resolved. In this article, for the first time, a novel stacked auto-encoder based partial adversarial domain adaptation (SPADA) model is proposed to solve the fault diagnosis problem in PDA situations. Two deep stack auto-encoders are first designed to extract representative features from the training data (source domain) and test data (target domain), respectively. Then, a weighted classifier based on Softmax is used to weight the features from the source and target domains. Meanwhile, another domain discriminator and label predictor using the Softmax classifier are adopted to simultaneously implement domain adaptation and fault diagnosis. Comprehensive analysis is performed on real data to test the performance of the SPADA model and detailed comparisons are provided; the extensive experimental results show that the diagnosis performance of SPADA outperforms the existing deep learning and domain adaptation methods in dealing with the PDA problem.
Imbibition behavior of offset inks - I: gravimetric determination of oil imbibition rate into pigmented coating structures

In this first part of a two-part paper, the authors examine the competitive rate of removal of ink vehicle from a setting commercial offset ink. The competition is established by the absorptive forces of a porous coating network acting against the progressive concentrating boundary film of the ink. The experiments were carried out gravimetrically with a compressed tablet of calcium carbonate coating pigment brought into contact with a supersource of oil (Part 1) and ink (Part 2). Results correlate well with the earlier prediction of fluid loss based on the increase in ink tack observed on commercial offset paper with an ink surface interaction tester. These supersource data confirm the finding from the thin film application that the weight fraction of oil lost from an ink is linear with time during the period when tack is increasing. The rate at which oil mass is lost from an ink decays according to an approximate inverse square law with time. The initial tack rise is characterized by the dominance of a preferred network absorption pathway. Application: Controlling the dynamics of a preferred network absorption pathway in relation to the total pore volume is a major factor in controlling the press runnability of coated paper in relation to the development of tack.
Factors Determining Sago Starch Import Demand: Empirical Evidence
 from Japan

*Corresponding author: Marlisa Ayu Trisia International Center for Research and Education in Agriculture, Nagoya University, Nagoya, Japan Tel: +81-52-789-4240 Fax: +81-52-789-4225 E-mail: trisiayu@agr.nagoya-u.ac. jp Abstract Sago starch (Metroxylon sagu Rottb.) is one of the starches imported into Japan. Recently, sago starch has been promoted as a healthy type of starch because it is gluten-free and non-allergenic. This study aims to identify the factors affecting sago starch import demand during the period 1978–2017 in Japan by using a double logarithmic linear function. The study revealed that the price of sago starch, GDP, aging population rate and tariff-rate quota policy are significant factors influencing sago starch importation in Japan.
ON THE IMPORTANCE OF TRADITIONAL LENDING ACTIVITY FOR BANKING SYSTEMS STABILITY

In this paper, we analyzed the role of banks’ traditional lending on systemic stability. Firstly, we quantified the effect of correlation among banks’ results on systemic risk through Monte Carlo simulation. Secondly, we verified how traditional lending affects banks’ results correlation. Finally, combining the two effects, we assessed the importance of bank traditional lending on financial stability. Our results suggest that banks devoting a higher share of their assets to traditional lending show a lower correlation of their comprehensive income, thus having a mitigation effect on systemic stability.
