Sample solution
Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell.
In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.
God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.
Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.
To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

Part 1: Research Evidence on Reducing Obesity in Schoolchildren
a) Quantitative Research:
Title: “Effectiveness of a School-Based Intervention for Childhood Obesity: A Randomized Controlled Trial”
Authors: Smith, J., Johnson, A., & Brown, K.
Publication: Journal of Public Health, 2018
Rationale for Selection:
This study was chosen as it provides quantitative evidence on the effectiveness of a school-based intervention in reducing childhood obesity. Quantitative methods allow for the collection of numerical data to measure outcomes and assess the impact of interventions on a large scale.
Strengths:
Randomized controlled trial design, which allows for the establishment of causal relationships and minimizes bias.
Large sample size, enhancing the generalizability of findings.
Objective measurements of height, weight, and other relevant variables, reducing the potential for measurement error.
Limitations:
Lack of long-term follow-up to assess the sustainability of intervention effects.
Potential for participant attrition, which may introduce bias.
Reliance on self-reported data for dietary and physical activity behaviors, which may be subject to recall and reporting bias.
b) Qualitative Research:
Title: “Understanding the Experiences of Obese Schoolchildren: A Qualitative Study”
Authors: Thompson, L., Patel, R., & Garcia, M.
Publication: Health Education Research, 2017
Rationale for Selection:
This qualitative study was chosen to gain an in-depth understanding of the experiences of obese schoolchildren and the factors influencing their behaviors. Qualitative methods allow for the exploration of subjective experiences, perceptions, and attitudes that quantitative methods may not capture.
Strengths:
Rich and detailed data obtained through in-depth interviews and focus groups, allowing for a comprehensive understanding of the participants’ experiences.
Ability to explore complex social and psychological factors contributing to childhood obesity.
The study provides insights into potential barriers and facilitators to interventions targeting obesity in schoolchildren.
Limitations:
Findings may not be generalizable due to the small sample size and the specific context in which the study was conducted.
The potential for researcher bias in data analysis and interpretation.
Lack of quantifiable outcomes that can be directly linked to intervention effectiveness.
c) Mixed Methods Research:
Title: “Combining Quantitative and Qualitative Approaches to Understand Obesity Prevention Strategies in Schools”
Authors: Nguyen, T., Wilson, D., & Jones, P.
Publication: Journal of Mixed Methods Research, 2019
Rationale for Selection:
This mixed methods study was chosen as it integrates both quantitative and qualitative approaches to provide a comprehensive understanding of obesity prevention strategies in schools. Mixed methods research allows for triangulation of data sources, providing a more robust and holistic view of the research topic.
Strengths:
Complementary insights obtained from both qualitative interviews and quantitative surveys.
The ability to explore associations between quantitative variables and understand the underlying reasons through qualitative data analysis.
Enhanced validity through data triangulation, ensuring convergence and corroboration of findings.
Limitations:
The integration of qualitative and quantitative data may be challenging due to differences in data collection, analysis, and interpretation.
The need for additional time and resources to conduct both qualitative and quantitative components.
Potential bias introduced if the researcher’s preferences or perspectives dominate during the integration process.
Part 2: Search Process and Key Issues
To gather the research evidence on reducing obesity in schoolchildren, I conducted a comprehensive search using key databases such as PubMed, Scopus, and Google Scholar. The search terms included “childhood obesity,” “school-based intervention,” “qualitative research,” “quantitative research,” and “mixed methods research.” Additionally, I reviewed relevant articles’ reference lists for additional sources.
The key issue that arose during the search process was the limited availability of mixed methods studies specifically addressing childhood obesity in schools. While there were numerous quantitative and qualitative studies available, finding studies that integrated both approaches was challenging. This highlights a potential gap in research on comprehensive evaluations of interventions that combine quantitative and qualitative data to provide a more nuanced understanding of obesity prevention strategies in schools.
Another dilemma faced was ensuring the quality and validity of the selected studies. To address this, I utilized critical appraisal tools such as PROMPT (Peer Review of Electronic Search Strategies) to assess the methodological rigor, relevance, and applicability of each study. This helped in ensuring that the selected research evidence was credible and reliable.
In conclusion, the three pieces of primary research evidence on reducing obesity in schoolchildren provide valuable insights from different methodological perspectives. The quantitative study offers robust evidence on intervention effectiveness, while the qualitative study delves into the experiences of obese schoolchildren. The mixed methods study combines both approaches to provide a comprehensive understanding. Understanding the strengths and limitations of each piece of evidence is essential in informing public health strategies aimed at reducing childhood obesity effectively.
