Effective Classroom Practices for Unlocking Students’ Potentials in Mathematics
Authors: Mkenda Theresia B 
Published: April 2022

Abstract
Despite several measures that have been employed by different stakeholders to improve the teaching and learning of mathematics subjects in Tanzania, the students’ pass rate in form four national examinations has been less than 25% for more than ten (10) consecutive years now. This persistent massive failure in mathematics can be highly associated with teaching strategies that are used by teachers when delivering their lessons, students’ attitudes toward the subject and the general school/learning environments that surround the students. This paper analyzes the most effective strategies that can be employed by teachers and other stakeholders to make mathematics lessons more meaningful and help students develop strong positive attitudes toward the subject, hence unlocking their potential in mathematics. These strategies were first compiled from a scoping review of previous scholarly works and then shared with mathematics teachers and students in selected secondary schools in the Kilimanjaro region of Tanzania to assess the practicability and relevance of the proposed strategies in daily teaching and learning processes. Additionally, the suggested strategies were used by Mwenge Catholic University students who participated in the volunteering programme of teaching mathematics subject in the selected schools during the Teaching Support Programme. Teachers’ feedback, students’ feedback and the lessons learned from the math Teaching Support Programme helped the researchers confirm the effectiveness of the proposed strategies and suggest promising interventions that can help to unlock students’ potentials in mathematics.

Abstract
Impact of COVID-19 has been devastating worldwide, it has disrupted lives of people, economy has fallen and millions of people have lost their jobs. Second peak of COVID-19 is making it even worse for many developing countries. In India, the second peak is reaching nearly 4 times the cases that were reported during the first peak, thus making it a challenge for the government to plan for the future without affecting the economy further. According to WHO, millions of enterprises are at existential threat, nearly half of the global workforce is at risk of losing their jobs and the entire food chain has been disrupted. In order to provide some assistance to the situation, this study aims to use the SIR-F Model, which is a variation of the SIR model. W. O. Kermack and A. G. McKendrick in 1927, proposed the model in which they classified a fixed population into three compartments: S(t), susceptible; I(t), Infected; R(t), Recovered. We have used the SIR-F model which differentiates between Recovered (meaning people infected and later recovered and thus now immune) and Fatality. We have simulated two scenarios including one in which we study the impact of medicine on future cases and also inspected various parameters which shed light on reasons behind increasing and decreasing the number of covid cases in India. In the future, this work can be extended further to develop a completely new model to consider those cases in which people have recovered but are still at a risk of reinfection.

Abstract
Background: Studies suggest increased risk for an outcome in people with joint exposures that share common causal pathways. The objective of this study was to determine the risk of incident acute myocardial infarction (AMI) following exposure to both albuminuria and/or anxiety and depression symptoms.Methods: Participants who provided urine samples to the HUNT2 (1995–97) or HUNT3 (2007–2009) surveys were followed until the end of 2016. Albuminuria was measured by Albumin Creatine Ratio (ACR) and participants self-reported mood and anxiety symptoms on the Hospital Anxiety and Depression scale. We used Cox regression to estimate hazard ratios (HRs) for first incident AMI considering interaction between exposures and additive models to calculate the proportion of AMI that were attributable to the synergy of both exposures, adjusted for the Framingham variables.Results: 11 014 participants free of previous AMI were eligible for participation, with 1 234 incident AMIs occurred during a mean 13.7 years of follow-up. For participants who had a healthier CVD risk profile, the HR for AMI of having both albuminuria (3-30 mg/mmol) and depression (≥8) was 2.62 (95% 1.12–6.05) compared with a HR 1.34 (95% CI 1.04–1.74) with raised ACR only (Likelihood Ratio-test 0.03). Adding anxiety (≥8) to albuminuria (3-30) tripled the risk (HR 3.32 95% CI 1.43–7.17). The additive models suggest that these risks are not higher than expected based on each risk factor alone. Conclusions: This study indicate that the risk of AMI in persons with elevated albuminuria but with an otherwise healthy CVD profile might be amplified by anxiety and depression symptoms. The increased risk with joint risk factors is not higher than expected based on each risk factor alone, which indicate that the risk factors do not share causal pathways.

Published: April 2022

Background:
Presenteeism is a significant factor that affects the quality of care provided by obstetric healthcare workers, including nurses, that needs further investigation of its connection to job stress and affective commitment during COVID-19 pandemic.

Aim:
The aim of this study is to examine the moderation effect of affective commitment on the relationship between job stress and presenteeism among obstetric healthcare workers during COVID-19 pandemic.

Methods:
Two hundred and seven Egyptian obstetric healthcare workers participated in a cross-sectional, descriptive study using a web-based questionnaire to collect data on sociodemographic, presenteeism, challenge stress, hindrance stress, and affective commitment.

Results:
More than 50% of obstetric healthcare workers had a moderate level of presenteeism, while job stress and affective commitment were at moderate to high levels. Affective commitment had a significant moderating effect on the relationship between job stress and presenteeism (p< .001). Challenges and affective commitment had a positive effect on presenteeism, while hindrances had a negative effect.

Conclusion:
Obstetric healthcare workers need to recognize the connection between job stress and presenteeism and the buffering role of affective commitment.

Implications for Nursing Practice:
Nurses need to recognize the effect of pandemic COVID-19 on job stress and presenteeism among obstetrics nurses and healthcare workers. Developing innovative protocols would enable them to improve their functionality and productivity at work.
Using the Stay Strong App for the Well-being of Indigenous Australian Prisoners: Feasibility Study
Authors: Perdacher Elke , Kavanagh David , Sheffield Jeanie , Healy Karyn , Dale Penny , Heffernan Edward 
Published: April 2022

Background
The gap between mental health needs and resources for Aboriginal and Torres Strait Islander people, the Indigenous people of Australia, is most marked in the prison population. Indigenous people are overrepresented in Australian prisons. In prison, this group experiences mental disorders to a greater degree than non-Indigenous prisoners. This group has also been found to experience mental disorder at a higher rate than Indigenous people in the community. In addition to pre-existing determinants of poor mental health, these high prevalence rates may reflect poor engagement in mainstream interventions or the efficacy of available interventions. In community populations, the use of digital mental health resources may help to increase access to well-being support. However, culturally appropriate digital tools have not been available to Indigenous people in prisons. The absence of feasibility and efficacy studies of these tools needs to be addressed.

Objective
The aim of this study is to determine the feasibility of the Stay Strong app as a digital well-being and mental health tool for use by Indigenous people in prison.

Methods
Dual government agency (health and corrective services) precondition requirements of implementation were identified and resolved. This was essential given that the Stay Strong app was to be delivered by an external health agency to Indigenous prisoners. Then, acceptability at a practice level was tested using postuse qualitative interviews with clients and practitioners of the Indigenous Mental Health Intervention Program. All Indigenous Mental Health Intervention Program practitioners (10/37, 27%) and client participants who had completed their second follow-up (review of the Stay Strong app; 27/37, 73%) during the study period were invited to participate.

Results
Owing to the innovative nature of this project, identifying and resolving the precondition requirements of implementation was challenging but provided support for the implementation of the app in practice. Acceptability of the app by clients and practitioners at a practice level was demonstrated, with nine themes emerging across the interviews: satisfaction with the current Stay Strong app, supported client goal setting, increased client self-insight, improved client empowerment, cultural appropriateness, enhanced engagement, ease of use, problems with using an Android emulator, and recommendations to improve personalization.

Conclusions
The Stay Strong Custody Project is a pioneering example of digital mental health tools being implemented within Australian prisons. Using the app within high-security prison settings was found to be feasible at both strategic and practice levels. Feedback from both clients and practitioners supported the use of the app as a culturally safe digital mental health and well-being tool for Aboriginal and Torres Strait Islander people in prison.

Authors: Wang Wentao , Cheng Jing , Song Weijun , Shen Yi 
Published: April 2022

Background
The prevalence of obesity in children and adolescents remains a global public health issue. Wearable devices may offer new opportunities for prevention and intervention in obesity. Previous systematic reviews have only examined the effect of the wearable device interventions on preventing and treating obesity in adults. However, no systematic review has provided an evaluation of wearable devices as physical activity interventions for preventing and treating obesity in children and adolescents.

Objective
The purpose of this review and meta-analysis was to evaluate the effectiveness of wearable devices as physical activity interventions on obesity-related anthropometric outcomes in children and adolescents.

Methods
Research articles retrieved from PubMed, EMBASE, Cochrane Library, Scopus, and EBSCO from inception to February 1, 2021, were reviewed. The search was designed to identify studies utilizing wearable devices for preventing and treating obesity in children and adolescents. The included studies were evaluated for risk of bias following the Cochrane recommendation. Meta-analyses were conducted to evaluate the effectiveness of wearable devices as physical activity interventions on body weight, body fat, BMI z-score (BMI-Z), BMI, and waist circumference. Subgroup analyses were performed to determine whether the characteristics of the interventions had an impact on the effect size.

Results
A total of 12 randomized controlled trials (3227 participants) were selected for meta-analysis. Compared with the control group, wearable device interventions had statistically significant beneficial effects on BMI (mean difference [MD] –0.23; 95% CI –0.43 to –0.03; P=.03; I2=2%), BMI-Z (MD –0.07; 95% CI –0.13 to –0.01; P=.01; I2=81%), body weight (MD –1.08; 95% CI –2.16 to –0.00; P=.05; I2=58%), and body fat (MD –0.72; 95% CI –1.19 to –0.25; P=.003; I2=5%). However, no statistically significant effect was found on waist circumference (MD 0.55; 95% CI –0.21 to 1.32; P=.16; I2=0%). The subgroup analysis showed that for participants with overweight or obesity (MD –0.75; 95% CI –1.18 to –0.31; P<.01; I2=0%), in the short-term (MD –0.62; 95% CI –1.03 to –0.21; P<.01; I2=0%), wearable-based interventions (MD –0.56; 95% CI –0.95 to –0.18; P<.01; I2=0%) generally resulted in greater intervention effect size on BMI.

Conclusions
Evidence from this meta-analysis shows that wearable devices as physical activity interventions may be useful for preventing and treating obesity in children and adolescents. Future research is needed to identify the most effective physical activity indicators of wearable devices to prevent and treat obesity in children and adolescents.
