Q1.  What role does the abstract play in the publication of an academic paper?       

A short overview of the article is the abstract. It is not an introduction to what follows. The main elements of the study methodology and the major results of the research are also described in full and succinct. The abstract is typically the initial interaction with a research or report by the reader and is at times the sole portion that is collected and/or examined in scientific databases. This feature offers the first and frequently most crucial impression that the study topic and outcomes have their own potential worth or significance. If the abstract is correctly written, readers should be asked to receive a copy of the entire manuscript that is included in the discovered ones. If the abstract is properly written, readers will be encouraged to receive a copy of the entire text included into those found. If the abstract is not worded properly, the study might be disregarded or even forgotten.

Q2.   What is the main focus of the study? 

The incorporation of Internet technology into education has offered various possibilities for study accessible to everyone worldwide. In addition to textbooks and classroom lectures via social media, students currently experience the sharing of ideas, resources and information as well as a tools for Undergraduate student learning. Online information and communication are provided free of charge to students on Facebook, LinkedIn, Instagram, Twitter, and many more platforms. The study discuss how social media use can improve learning.

                                                                                                                             

Q3.  What are digital natives? Discuss whether there are digital natives in your home country. 

 

Every person who was born in 1980, the digital natives, who have a direct touch with technology in their biological and social development. There are some behavioural changes and everyday habit that affect their schooling, job plans, and living objectives in an ever larger context for this generation, which was born around technology. No wonder as a part of globalisation my home country has digital native. Their habits, behaviours and preferences in consumption have guided the strategies of numerous brands that want to distinguish themselves on the market, companies that strive to improve communication and institutions of education which attempt to adapt their educational techniques to digital lifestyles.

Q4.  What does the term ‘social media’ mean?  Do you think the use of social media will change in the future?    

Social networks facilitate social relationships and interact between individuals, groups or organisations, which share the same values or interests. The internet and social media development have broadened this notion.  After all, a social network's fundamental role is to connect individuals inside the virtual world, either to develop new social links or to maintain current social ties. There is no denying the achievements of the social networks we know, like Facebook and WhatsApp. Without their presence, we can scarcely conceive of our social contacts and this illustrates the power of these platforms, which take the world as we know it.

Social networks represent all the improvements in technology that society has accomplished and must consequently include social actions. Artificial intelligence research are already underway to assist blind people understand photos. Another initiative seeks to facilitate diagnosis, through the examination of photographs of the patient, of illnesses such as skin cancer.

                                                                                   

Q5.  Discuss the positive and negative effects of using social media in class. 

     Many kids cannot deal with the wide-ranging web-based knowledge. Many consider what they read on the web as the absolute truth, and this affects the learning process and the formation of a critical view of what is given. The social networks' popularity and the pace of online interactions have brought about new methods of writing and speaking, transformed and revealed Portuguese. This might impair the writing quality of these young people since the internet language in our culture has not yet become normal and is still restricted to the online media. Socialization is an evolving activity - we are seeking interaction with certain individuals on social networks rather than immediately addressing those who are accessible around us at any given time. Special attention should be paid to this behaviour, which undergoes a lot more difficult and rapid changes than ever before. Technology is a tool that needs to make the interaction easier, more efficient—in short, media. It is important to be conscious that it is not the mechanism that guides our decisions. Generally speaking, this happens when we utilize a technology without knowing the influence it has on our own conduct completely.

                                                                                                                               



Q6.  Explain how the researchers collected their data. Was this an effective means of doing it?         

Survey is a very frequent technique of study by which researchers themselves enter the field to gather data. Research in the field can be utilized as a dissertation technique of research and gathering of data. Different methods, such as surveys, interviews and observations, may be utilized. In order to gather the exact data needed to answer research questions and to test hypotheses, the researcher will.

Q7.  What were the five research questions?  Give an explanation of each one. 

1. What social media accounts do undergraduate fine arts students have? 

2. How often are these students accessing social media accounts? 

3. To what degree do these students use social media for educational purposes? 

4. To what degree does social media use contribute to these students’ education? 

5. To what degree does social media use distract these students from their college education?

Q8.  In the following reference what is ‘In Education’ and what is ‘15(1)’?     

Hoffman, E. S. (2009). Social media and learning environments: Shifting perspectives on the locus of control. In Education, 15(1), 23-38. 

‘In Education’ is the name publisher and what is ‘15(1)’ is volume number      

Q9.  What are your opinions on the use of social media in class?  Has the use of social media helped you in your studies? 

Social media has mixed impact on my study sometimes it accelerate the information gathering process other times it creates a lot of distraction. Its require a huge self control to stick to the study while using social media.  

Q10.  Overall, what conclusion did the researchers reach?  Discuss whether it is justified quoting examples from your own experience. 

         

 The Results showed that Facebook was the most popular account, followed by Instagram, Snapchat, and Twitter, that is similar to my using pattern. Logging on to their top social media accounts was a combined total of 32.82, while the weekly average was a combined total of 226.39. That is also similar to my usages.  Of the students surveyed, 49% marked agree or strongly agree that they used social media for educational purposes, I would agree if I was asked the same. A total of 39% of surveyed students responded that they had a class that required use of social media. Which I agree. and the final research question which is the  comparable levels of distraction from social media use (78.65%) compared to face to face interactions (74.27%) is also similar to me                                                                                                                          

Q1. The abstract provides a short overview of the key elements of a research paper. It summarizes the main points of the study including the methodology and major findings, without going into too much detail. The abstract gives readers a first impression of the research and helps them decide if they want to read the full paper.

Q2. The main focus of the study is on the use of social media as a tool for undergraduate student learning. It examines how students are using social media for educational purposes and how it contributes to or distracts from their learning. 

Q3. Digital natives are those born after 1980 who have grown up with technology. They have different behaviors, habits, and preferences shaped by digital technology. Yes, there are digital natives in my home country as a result of globalization and widespread access to technology. 

Q4. Social media refers to online platforms that allow users to create and share content, interact, and develop social networks. I think social media will continue evolving in the future with advances in technology like AI to enhance accessibility and capabilities. But the core function of connecting users will remain.

Q5. Positives of social media in class include easier access to information and collaboration. Negatives are potential distractions, improper online behavior, and overreliance on unverified online sources instead of critical thinking. 

Q6. The researchers collected data through an online survey completed by undergraduate students. This seems an effective means of gathering information directly from the target demographic. 

Q7. The five research questions focused on: 1) Types of social media accounts students have 2) Frequency of social media use 3) Use of social media for education 4) Contribution of social media to education 5) Distraction of social media from education

Q8. 'In Education' refers to the journal name. '15(1)' indicates it is Volume 15, Issue 1 of that journal.

Q9. I think social media can help access information quickly, but it requires self-control to avoid distractions. It has helped my studies but also sometimes distracts me. 

Q10. The study found high social media use among students comparable to my experience. Around half used it for education and found it contributed to their learning, which aligns with my opinion. However, levels of distraction were also high, consistent with my observations. The conclusions seem justified based on my own experiences as a student.

Leadership and Organizational Culture at Nitol Niloy Group: How Leaders Shape Shared Values and Drive Adaptability | 522 WORDS ESSAY

Leadership and Organizational Culture at Nitol Niloy Group 

How Leaders Shape Shared Values and Drive Adaptability

 Nitol Niloy Group PRODUCTS

Nitol Tata follows the Functional Organization model whereby each division, headed by a Executive Director. The new firm quickly established itself as a key participant in the commercial vehicle industry, and it has continued to develop since then. The firm began as a car trade company with the principles of quality, honesty, and efficiency (Nitol Motors Limited, n.d.). International firms attracted its strong sales figure and Nitol Motors Ltd. became Bangladesh's exclusive distributor in 1989. In 1991 a joint venture was created between TELCO and NITOL, called Nita Company Ltd., for the assembly in Bangladesh of TATA cars. Nitol-Niloy Group literally became a domestic brand in less than 20 years from a trading firm in the early 1980s. The Nitol Niloy Group adopts the paradigm of a Functional Organization, which focuses on its distinct functional objectives by each division led by a Managing Director with a considerable education and industrial experience. The thesis on the Nitol Motors Limited section and its service department has been brought to the fore. Culture is established via values, beliefs or perceptions shared inside an enterprise by personnel. In practice it is a collection of rules and standards which, via words, interpersonal connections and gestures, lead to the cultural assumptions of its members. Image shows the three components, artifact, shared values and assumptions of organizational culture It's learned collectively. Image of 3 components, artifacts, common values and assumptions in corporate culture the members of the organization, but particularly the leadership, who play a major part in its awareness, learns and transmits it collectively. Because the activities of workers are influenced significantly in times of development or adaptation to change (Tata Motors in partnership with Nitol Motors launches the all-new Tata LPT 1212 light commercial vehicle in Bangladesh, n.d.). Managers also form and bear the responsibility for the development of the culture: they establish mission, vision and purpose, build the framework that guides and empowers the business. And they will be accountable for leading those who lead to it once formed.  

The leaders of the companies spread the culture of the firm to their teams and groups (Hossain, 2016). They guarantee that all characteristics described as the culture of the firm are matched by the personnel and operate in accordance with the goals of the organization. Furthermore, the leader works together to prevent staff from deviating from what is anticipated. In some institutions, the responsibility of management to help create a culture that reflects the goals of the institution and guides everyone on the same road is not fully defined yet. The leader enables their employees to discover satisfaction.  

The culture of the Nitol Tata is formed through leaders' activities. When values are dysfunctional, leadership helps the team to unlearn certain inefficient cultural assumptions and adopt new models. Otherwise, the sectors cannot adjust to the required changes without the figure of a leader who centralizes the team (Business Structure Comparison Chart for Bangladesh (LegalSeba, n.d.). The same traditional ideals so remain intact and the firm is not adapted to changing strategic circumstances. But it is a deadly mistake to keep up with the same positions in a continually shifting market. Tech periods like this require fluid information, process agility and adaptable ability. It is also important that the leader is active providing continuous feedback to every employee and lists the items that merit attention to be low-performance and the elements in which the team works effectively. Without this, employees believe that anyone higher up the hierarchical pyramid may read them as a mere number. The manager becomes united with the group and preserves the organizational culture at best by fostering a roundtable with work colleagues.

The Evolution of Language Teaching: From Audiolingual Methods to Learner-Centred Communicative Approaches | 400 essay

The nature of approaches and methods in language teaching

language teaching approaches, teaching methods, audiolingual method, communicative language teaching, conceptualization of approaches methods and techniques, evolution of language teaching, learner-centered teaching.

An approach is a series of correlated assumptions concerning the nature of language acquisition. The method is an overarching strategy for the orderly display of linguistic material which does not contradict the approach chosen and is all based on. A technology that takes place in a classroom is implementation. Techniques should be method-compatible and therefore in line with an approach. From the 1970s through the 1980s, language learning changed significantly. The search for new techniques and methodologies based on grammar led to numerous distinct routes. The rising interest in communication approaches to language education was adopted by mainstream language teaching. The communication movement attempted to shift the focus from grammar as the key component of language to a different perspective of language, language acquisition, teacher and student, focusing on linguistic transmission and turning the classroom into a real communication setting. Part III discusses this "communicative movement" and associated techniques. However, at this era there were also various directions for language instruction. 

Whereas audio language and instruction were mainstream teaching techniques that were designed by linguists and applied linguists, the approaches and approaches mentioned in this section were established outside the field of mainstream language education. In the former scenario, the revolutionary approaches from the 1970s, such as Total Physical Reply, Silent Way, Consulting Learning, , Neurological Programming and Multiple Intelligences are used. These approaches are developed rather than based on the philosophy of language and the research and theory in applied linguistics. Another approach, known as the Audiolingual Method, provided a proposition substantially distinct from those previously in force (MA). 

As an alternative rapid learning option for troops, and aimed at teaching the foreign language through conversation and repetition activities, with little or no instructor explanation, aiming at a skill close to that of a native. This approach was founded on Skinner's theory of behaviour, in which learning is the acquisition of new behaviour and these behavioural stimuli are strengthened by strengthening the desired behaviour’s techniques are created around distinct conceptions of learners, sometimes theory of a single theorist or educator rather than starting from the theory of language or depending on research and theory in applied linguistics. Consequently, these approaches are relatively undeveloped in the realm of language theory, which typically distinguishes them from theory found in second-language learning literature. 

Therefore, linguistic practice at the time concentrated nearly solely on second language acquisition (ASL), interpreted like any other foreign and second language. From then on, instructional techniques are applied and approaches are more detailed. Consequently, we offer an overview of some techniques below, which will then assess if a multiliteracy discipline practice is viable or not.

A brief history of language teaching | 300 words essay

A brief history of language teaching

People can process language very quickly and reliably. That is why there are many people in the world is bilingual now. But the history of learning second language was not always easy like now. The Latin language progressively lost its dominating position with the fall of the Roman Empire and in the early Middle Ages when it became a dead language, a language no longer commonly spoken, but nevertheless used to be taught. 

Explorers and missionaries enhanced the language knowledge of the 16th, 17th and 18th centuries. In opposition to the Latin grammar paradigm which is deemed universal, the Renaissance of exotic linguistic features. The description is contrasted (different from Latin and/or Romantic). Language description Theory of speech components is a framework. In particular, missionaries act as the protagonists of a pedagogical proto-linguistic, that is, a lack of dialog between eurocentrism and subjectivity. These phenomena originate from the history of linguistic and educational tools, the two principal instruments of which are grammar and dictionary. Latin language teaching helped to the evolution of language pedagogy, foreign language studies for history, language documentation. The role of explorers and missionaries in language teaching and the development of grammar and dictionaries as well as democratization of language learning.

They belong to the communication of meta-linguistic knowledge and the connection between language and linguistic instruction. In addition to the major investigations in Asia, the Americas, Africa, and Oceania, the conference will give a chance to analysis the spread and appropriation of education and learning techniques from the colonial and neo-colonial past. It will be a chance for analysing how the teaching and learning techniques of major voyages were disseminated and appropriated in Asia, America, Africa and Oceans, throughout colonial and neo-colonial times. Abroad language studies have become "democratized" in the sense that more and more individuals are being able to access them since they are less expensive. The continuous research discussions have been based on the effect of cultural history contributions and curriculum history. It helped us to understand the uses and speeches that were made of Latin in contemporary times. 

Its contents, but also its animating will, as well as the strategic groundwork that served as a basis for the creation of foundations of the education system appear extremely crucial to us. Latin persistence in classical sciences has taken the upper hand beyond the various political and ideological systems and has placed itself firmly at the heart of the western civilization. The aims articulate the humanities class in so far as they have been able to contribute to creating Latin style in the students, to their knowledge about antiquity and traditions and their knowledge were cognitive, rhetorical, religious and moral. their habits and their religion growing. In the context of a pedagogic approach with tightly interwoven goals, the study of Latin could not be seen as a "discipline" controlled for itself: the text studied was the chance to communicate, including lyrical and rational texts, the ancient past.

3.1: Explain the use of the barium meal for soft body imaging

Lesson 5 of 11

The use of ionising radiation in medicine includes both monitoring and treatment of patients and falls into two broad categories; radiography and radiotherapy. Radiography involves the production of an image to monitor or diagnose medical conditions (‘graph’ = from the Greek ‘to draw’ or ‘describe’), whereas radiotherapy involves some form of treatment of a disorder (‘therapeia’ = Greek for ‘healing’). 

https://youtu.be/EqGqsXF20zA

Radiotherapy

–

Radiotherapy uses ionising radiation to destroy cancer cells, and around 40% of people diagnosed with cancer will have it as part of their treatment. It can also be used before surgery to shrink a tumour so it’s easier to remove, or after surgery to kill off any cancer cells that survived the operation.

As an external process, high energy x-rays are focussed onto the patient in a very specific target area. The radiation damages cancer cells, causing them to die or stop growing. Healthy cells nearby are also damaged, but these are usually able to repair themselves and recover.

The patient needs to be positioned very carefully on the table of the machine to ensure that only the affected area is treated with the radiation beam.

Radiotherapy may also be delivered to a patient internally, using radioactive liquids and implants to attack cancerous cells more directly. Implants maybe wires and tubes placed in the patient to release radiation near cancer cells, then left in the body for a period of time from a few minutes to maybe days, or sometimes permanently.

3.2: Explain the use of γ-rays in imaging

Lesson 6 of 11

We learnt earlier in this unit that x-rays are produced by controlled electron bombardment in an appropriately designed machine. Gamma rays are very similar to x-rays but are produced by radioactive decay inside the nucleus of an atom.

If it helps to think of the radioactive nucleus as a tiny x-ray machine, you may start to appreciate how useful this may be. Radioactive nuclei can be attached to substances that can be put into the human body, which then produce detectable radiation from wherever those substances end up. These radioactive ‘tracers’ can be delivered into the body, by injection, ingestion, or inhalation, and by choosing appropriate radionuclides and carrier molecules the tracers can be targeted to specific body systems, specific organs, or even specific types of cell.

 Whereas x-rays are useful is providing us with an image of the body’s anatomy, i.e. what it looks like, gamma ray imaging provides us with a means to visualise what the body is doing. It provides a ‘functional’ image of the processes taking place in particular organs or development of tissues and bones.

    https://youtu.be/b5YzpBuV0fs

https://youtu.be/yrTy03O0gWw

 

Radioactive liquids to treat cancer are given either as a drink or by injection. Examples include:

⦁    Radioactive phosphorus – used for blood disorders

⦁    Radioactive radium – used for cancer that has spread to the bones

⦁    Radioactive strontium – used for secondary bone cancers

⦁    Radioactive iodine – used for benign thyroid conditions and thyroid cancer.

 As with the radioactive tracers used in PET scans described earlier, the radioactive part of the liquid may be attached to another substance, which is designed to take the isotope into the tumour.

Radioactive implants

Internal radiotherapy implants are radioactive metal wires, seeds, or tubes put into your body, inside or close to a tumour. In temporary brachytherapy, a highly radioactive material is placed inside a catheter or slender tube for a specific amount of time – often just a few minutes, sometimes a few days – and then withdrawn. The radiation dose is determined by the activity of the radioisotope and the duration of the treatment.

 In some types of cancer, small metal implants, or seeds, are left in the body permanently – this is known as permanent brachytherapy. These implants may be made of radioactive gold or contain radioactive iodine or another appropriate radioisotope. They give a very high dose of radiation to the area of the cancer cells. The radiation dose in this case is determined by the activity of the radioisotope and its half-life (see below).

 4.1: Explain how technetium-99m is generated

Lesson 8 of 11

Sources of radiation that are administered to humans internally have to be chosen carefully. By injection, ingestion or inhalation, a patient is given a low dosage radioisotope that is targeted to reach a specific organ. The radioisotope needs to produce radioactive emissions of sufficient strength to impact the organ to be treated, or to be detected by the sensors. We do not want to cause danger to the patient’s health, however, by prolonging their exposure to the radiation longer than is necessary.

Isotopes

As we discovered earlier, the number of protons in an atom determines what element it is, e.g.

One proton = hydrogen

Two protons = helium

Six protons = carbon

79 protons = gold

 …and so on.

Different number of protons = Different element

If the number of protons in the nucleus changes, it becomes a different element. But if the number of neutrons changes, we have the same element but with a greater or lesser atomic mass, and which is potentially unstable.

An isotope is an atom with the same number of protons, but a different number of neutrons. For example, the most common form of Hydrogen has just one proton and a single orbiting electron. If it had an extra proton it would become Helium, a different element. But if it has an extra neutron or more, it just gains mass and becomes more unstable. If an atom is unstable, it is likely to break down and emit radiation. This is radioactive decay.

https://youtu.be/pnlO_5NLkbg

Barium sulphate, as used in a ‘barium meal’ procedure described earlier, has a half-life of only 10 days. That means that after 10 days half the radioactive atoms have decayed; and after 50 days (five half-lives) 90% of the radioactive atoms have decayed to a stable product. Though in fact most of it will have been removed from the body by ‘natural biological functions’.

By contrast, carbon-14, as used in ‘carbon dating’ processes, has a radioactive half-life of around 5700 years. That means that something excavated from the Bronze Age, circa 3300BC, will contain around half the number of carbon-14 atoms that it had when it was buried.

Technetium-99m is a radioactive tracer that is used in twenty million medical diagnostic procedures per year. It is used for imaging and studying organs such as the brain, heart muscle, thyroid, lungs, liver, gallbladder and kidneys, as well as the skeleton and blood and for the investigation of tumours.

It does not occur naturally, so let’s have a look at its ancestral line of isotopes.

6.1: Explain the use of ultrasonics in medical imaging and treatment

Lesson 11 of 11

What is a sound wave?

A sound wave is a sequence of vibrations in the air or other medium. They are ‘pulses’ that travel through materials as the particles are compressed together and stretched apart. The vibrations travel through air at a speed of 340 metres per second; in solids the vibrations travel much faster. At higher altitudes, where the air is thinner and the molecules are spaced further apart, sound travels much slower. In a vacuum (like space), sound cannot travel through at all. This is because there are no molecules to transfer the vibrations.

https://youtu.be/qNf9nzvnd1k

Piezoelectric crystals vibrate in response to an alternating voltage, and when placed against a patient’s skin and driven at high frequencies produce ultrasound pulses that travel through the body. As they travel outwards and encounter different layers within the body the ultrasound waves are reflected back towards the source.

The returning signal drives the crystals in reverse and produces an electronic signal that is processed to construct the image.

Here’s a ‘60 seconds of science’ explanation that covers the ultrasound scanner.

https://youtu.be/I1Bdp2tMFsY

Applications of ultrasound imaging

Ultrasound is used to help physicians investigate symptoms such as pain, swelling and infection, and can help to diagnose a variety of conditions in most of the organs of the body including the heart and blood vessels, the liver, kidneys, brain, and eyes. Ultrasound of the heart is commonly called an “echocardiogram” or “echo” for short. It can scan for abnormalities and tumours in the breasts, testicles, and thyroid. It is frequently used to scan the foetus in pregnant patients, and to examine the hips and spine in young infants.

Ultrasound is also used to guide procedures such as needle biopsies, in which needles are used to sample cells from an abnormal area for laboratory testing, and to guide radiotherapy implants such as used to treat prostate cancer.

 A variation on the standard ultrasound scan is ‘Doppler ultrasound’, which can provide important information on blood flow.

To study the health effects of Hanford's iodine-131, researchers investigated a group of people with a wide range of radiation doses to the thyroid. In this way, researchers could compare groups of people with similar characteristics (such as lifestyle and diet) but different levels of exposure.

Other studies suggest that young children may be the most susceptible to the effects of radiation on the thyroid gland. Therefore, the HTDS selected participants who were young children when Hanford releases of iodine-131 were highest. Scientists also ensured that the HTDS participants included many people who lived in areas around Hanford where the highest thyroid radiation doses occurred.

From a sampling of 5,199 birth records, scientists were able to locate 3,440 people who were both willing to participate and able to provide the necessary data for evaluation of thyroid disease.

Participants underwent complete evaluations for thyroid disease, and provided detailed information about the places they lived and the quantities and sources of the food and milk they consumed.

For each type of thyroid disease, the research team examined how the rates of disease varied in relation to participants' estimated radiation doses from Hanford's iodine-131.
