Feedback Group 6 Friday Morning Classregarding Your Group Assignme ✓ Solved

Feedback - Group 6 (Friday morning class) Regarding your group assignment, my marks follow the Kent Institute Australia (KIA) criteria. I found several inconsistencies in all sections of your report, in terms of research, references, content, and structure. In terms of references, your group did not follow the unit guideline (Harvard referencing). Besides, there are several missing sources in your assignment, and those presented are not related to or integrated with the rest of the report. As there is no indication of the source your group used, this is considered MISCONDUCT (remember the Academic integrity survey? - ‘Using other people’s work - especially that of published researchers - without quoting, citing, and/or referencing accurately.

This is plagiarism’). Furthermore, I noticed that there is only one academic source. A minimum of 5 ACADEMIC sources in work being presented for this assignment. Your group lost points as your report presented only one academic source. Moreover, Investopedia and blogs are not reliable sources of research.

As it was described in the unit assessment brief, this type of source “is acceptable as a starting point to gain knowledge about a topic, but should no be over-used - these should constitute no more than 10% of our total list of references/sourcesâ€. Your group reported 7 references, therefore, it should have just one source. It has 2. Finally, you should have read the Harvard referencing workbook provide by KIA Academic Learning Support (ALS). Your whole referencing section used APA referencing.

It seems harsh, but that was the rule written in your unit guideline (Assessment Brief 2), and rules are made to be followed. In this sense, the lack of credibility of your sources affected your overall score in terms of references and research. In relation to the content and structure, your report lacks coherence, as it presents many inconsistencies with flow and analysis. As a starting point, there is no table of contents. A table of contents is important to orient the readers as well as it provides links to the sections.

Another issue is that the introduction does not have any links to the main body of the report. A good introduction should set the direction and goals of the essay as well as prepares the reader what the report is going to be about. Besides, your introduction basically paraphrased the whole Bigcommerce page. It can be considered little evidence of research and analysis. Furthermore, your group reported the history of other companies (Book Stacks, Amazon, Etsy, Apple Pay, etc.), which has nothing to do with Alibaba and should have not been in this report.

In other words, in 30 lines of your group introduction section, only ONE LINE talked about Alibaba. Thus, for all of these reasons your group lost points. The organisation overview, business model, and website sections presented a superficial analysis of Alibaba as a business. For instance, in the background and organisation overview, your group started describing the history of Alibaba without presenting any source. As there are no indications of the sources your group used, it could be considered MISCONDUCT.

Although it provided some description of the business, your report did not describe the structure of Alibaba in terms of management. In the business model section, I noticed that the sources in your report have no relation at all with your in-text citations. I downloaded and checked ALL your sources (one by one) and I compared them with your in-text citation. No matches were found. Thus, as there are no indications of the sources your group used, it could be considered MISCONDUCT.

I could have stopped here as the information was modified. In the website content section, your group described the website and its features. There is no mention of the source your group used. In the hardware infrastructure section, there is a source (Alibabagroup.com, 2021), which, by the way, is technically wrong according to the Harvard referencing workbook. Besides, I checked this source and it has no relation at all with the in-text citation.

This is considered MISCONDUCT (Using other people’s work without quoting, citing, and/or referencing accurately’.). In the software section, the same issue: No sources (MISCONDUCT). Your group did not describe the software Alibaba uses. Your group basically described the whole software section in ONE LINE!!! It is considered little evidence of research or this section was poorly addressed.

Concerning SECURITY ISSUES, your group started with irrelevant information about Cloud, IaaS, etc. which has nothing to do with this section. Again, your group in-text citation (Alibaba Cloud Community, 2021), which, by the way, is technically wrong according to the Harvard referencing workbook has no relation to the references. This is considered MISCONDUCT. In the payment section, your group basically paraphrased the entire GRONKVIST's BLOG. This can be considered little evidence of research and analysis.

In the discussion section, your group argued about things that were not discussed in any part of your report (e.g.: †…The pandemic can comparatively be said to have propelled the increased use of e-commerceâ€, “… the future of marketing and selling is online… “etc.). How did you get this information from?. There are no sources. Thus, this is considered MISCONDUCT. In the recommendation section, again your group argued about things that were not discussed in any part of your report (e.g.: †…Alibaba should discover data on the remote market… reduce tediousness…â€, “…can propel the organization even to a great scale…â€, “… use other development apparatuses, such as accessible links…â€, etc.).

Besides, your group did not point out in any part of the report that Alibaba has issues with TEDIOUSNESS (or whatever it means in your report), scalability, accessibility, identification, and so forth. Finally, your conclusion does not clearly summarise your essay and there are no clear links or connections to the introduction or main body. Again, your report talked about something that was not discussed in-depth in the previous sections. Thus, as you can see, my marks were based on the quality of your group report. Besides, your group lost points, because it DID NOT follow the unit guideline (Harvard referencing).

I was expecting more from your group as your group presentation was good. Unfortunately, your group report does not match your presentation. Hope this feedback can help you in your future assignments. Kind regards, Domingos PART A Nearly all the antibiotics used to stop bacterial infections are natural compounds that come from microbes themselves. For example, penicillin is derived from a fungus, while vancomycin, the antibiotic used when bacteria are resistant to many other drugs, comes from a bacterium.

Furthermore, although many antibiotics are chemically synthesized to resemble natural antibiotics, the “models†for them are natural products of microbes themselves. As more bacteria become resistant to traditional antibiotics, alternative drugs must be found. Recently, scientists discovered a completely new type of antibiotic that comes from Hydra, pictured above, a small freshwater creature famous for regenerating itself when its tissues are severed. While investigating defensive mechanisms on the skin of hydras in 2008, scientists at the University of Keil in Germany came across a protein that is active against both gram-negative and gram-positive bacteria. Most importantly, it works against some drug-resistant strains of bacteria.

They named this protein hydramacin. - Can you imagine why microbes produce chemicals that are inhibitory to other microbes? - What enables a new drug to be effective against bacteria that are able to resist old drugs? - How do you suppose the scientists figured out that the compound in Hydra acts against both gram-negative and gram-positive bacteria?

Introduction

The immune system is a complex defense mechanism that protects the body from pathogens. Understanding how various factors influence immune responses is essential for addressing diseases effectively. This essay will address four significant questions regarding the relationship between smoking and lung infection, the immunologic process behind tuberculosis (TB) diagnosis, the emergence of natural immunity to novel agents, and the critical role of super-antigens in severe infections.

First-Line Defense Mechanisms Impaired by Smoking

Individuals who smoke have a notably higher incidence of lung infections, primarily due to the impairment of several first-line defense mechanisms in the respiratory tract. The respiratory system is lined with mucosal layers that help trap harmful pathogens and particulate matter through a mechanism known as mucociliary clearance. This process relies on cilia—tiny hair-like structures that beat in a coordinated manner to move mucus upwards and out of the airways. Smoking leads to the dysfunction of cilia, decreasing their movement and effectively slowing down the clearance of pathogens such as bacteria and viruses (Cohen & Sborov, 2020).
Moreover, smoking compromises the integrity of the respiratory epithelium. Chemicals in cigarette smoke, such as formaldehyde and acrolein, can cause damage to the cells in the airway lining, leading to increased permeability and a greater likelihood of pathogens penetrating the barriers (Eisner et al., 2020). In addition, smoking has a detrimental effect on the local immune response by suppressing macrophage function. Macrophages play a critical role in phagocytosing pathogens and presenting antigens to T-cells. When compromised by smoking, their ability to clear infections decreases, further predisposing smokers to respiratory infections (Wang et al., 2021). Consequently, the combination of impaired mucociliary function, damaged epithelial barriers, and reduced macrophage activity collectively elevates the vulnerability of smokers to lung infections.

Tubercles Formation in Tuberculosis

The diagnosis of tuberculosis (TB) often involves identifying tubercles during X-ray imaging. This process correlates with a specific immunologic response in the body, marking the transition from a healthy immune response to a chronic infectious state. Tubercles form as a result of a process known as granuloma formation, which is initiated when the body attempts to contain the Mycobacterium tuberculosis bacteria. This pathogen has a unique lipid-rich cell wall that prevents its destruction by macrophages (Cohen, 2020).
The formation of tubercles involves a cascade of immune responses that recruit various immune cells, primarily macrophages, T-helper cells, and multinucleated giant cells, to the site of infection. Initially, macrophages attempt to engulf the bacteria, but due to its resistance, the microbes can survive within these cells. Activated T-helper cells (CD4+) play a crucial role in orchestrating the immune response, enhancing macrophage activity through the secretion of cytokines (Raviprakash, 2021). If the bacteria remain, the chronic immune response leads to the formation of a tubercle, a structured lesion that serves to contain the infection but can also lead to tissue damage over time. Thus, the presence of tubercles is indicative of an immune response aimed at managing the chronicity and inflammation associated with tuberculosis.

Natural Immunity and Laboratory-Created Biological Agents

Human immunity to pathogens traditionally develops through exposure to these agents; however, the statement claiming that humans would never develop natural immunity to a novel biological agent created in a laboratory is more nuanced. On one hand, laboratory-created biological agents, especially those engineered to evade immune detection or designed to mimic existing pathogens, may present challenges in developing natural immunity. For example, genetically modified pathogens can alter their antigenic profiles to avoid recognition by the immune system, complicating the development of immunity (Krammer, 2020).
Nonetheless, the immune system is characterized by its adaptability and capability of learning. Humans have successfully developed immunity against various pathogens through vaccination strategies and natural infections. An example is mRNA vaccines designed against SARS-CoV-2, which have successfully equipped the human immune response to combat a novel virus (Wrapp et al., 2020). Hence, while the uniqueness of laboratory-created organisms may pose initial immunity barriers, it cannot be universally stated that humans will never develop natural immunity to these agents. Factors such as vaccination history, immune system versatility, and environmental interactions can influence the potential for natural immunity development even against engineered pathogens.

The Role of Super-antigens in Severe Infections

Super-antigens, such as the toxic shock syndrome toxin (TSST) produced by Staphylococcus aureus, play a unique and often perilous role in immune responses. Unlike conventional antigens, which require processing and presentation by antigen-presenting cells (APCs), super-antigens have the ability to directly activate a large number of T-cells by binding simultaneously to the T-cell receptor (TCR) and MHC class II molecules (Wang et al., 2020). This non-specific activation can lead to an overwhelming immune response.
As super-antigens activate numerous T-cells, there is a massive release of pro-inflammatory cytokines, often referred to as a "cytokine storm." This excessive cytokine release can lead to life-threatening symptoms, including shock, multi-organ failure, and death (Miller et al., 2020). The abrupt rise in inflammation can overwhelm vascular systems, leading to reduced blood pressure and impairing organ function. Consequently, while the immune system’s hyperactivity may initially seem beneficial in combating an infection, it can have devastating consequences—exemplified by the life-threatening conditions associated with super-antigen exposure.

Conclusion

Understanding the interplay between various factors affecting the immune system illuminates the complexities of infectious diseases. Smoking can impair first-line defense mechanisms, placing individuals at increased risk for lung infections. In the case of tuberculosis, the immunologic processes leading to tubercle formation reflect a robust, yet sometimes unsuccessful response to chronic infection. While laboratory-created biological agents challenge the conventional conception of natural immunity, human adaptability may still pave the way for future immune defense developments. Finally, the paradoxical role of super-antigens in eliciting powerful but potentially hazardous immune responses underscores the need for careful consideration in managing infections associated with such toxins.
