    Task details

    Prepare a written briefing document. Using the dataset provided, identify demographic, social and behavioural factors that are associated with routine check-up attendance.

    Assessment criteria

    This assessment will measure your ability to:

    • Write an effective summary that clearly articulates a key message (25%)
    • A summary of the design of the BRFSS, its limitations and a comparison with a peer-reviewed paper (10%)
    • Description of the population (20%)
    • Examination of the association between four social and/or behavioural factors and routine check-up attendance (40%)
    • Appropriately format and organise the written assignment (5%)

    Refer to the Rubric for marking and feedback information.

    Instructions

    Scenario:

    A generation ago, people used to see their doctor only when they were sick or dying. Today, preventative health care is becoming commonplace as people become more educated and empowered about their own health. Regular, routine medical check-ups can help find potential health issues before they become a problem. Early detection of problems gives the best chance for getting the right treatment quickly, avoiding any complications.

    You have been employed as part of an active public health campaign that is aiming to increase routine 12-monthly check-ups. Your job is to analyse a subset of variables (as indicated below) and describe the association between these variables and routine check-up attendance and highlight the people with lower rates of check-ups in the last 12 months where a targeted campaign would be of most benefit.

    The Behavioral Risk Factor Surveillance System (BRFSS) is a collaborative project between all of the states in the United States (US) and participating US territories and the Centers for Disease Control and Prevention (CDC). The BRFSS is a system of ongoing health-related telephone surveys designed to collect data on health-related risk behaviours, chronic health conditions and use of preventive services from the non-institutionalised adult population (18 years) residing in the United States. Using the prepared BRFSS data, identify demographic, social and behavioural factors that are associated with routine check- up attendance.

    Dataset: The data set is updated each time the subject runs. You can access the relevant file on the main assessment page under Assignment 4.

    Format:

    Your written briefing document must consist of a 250-word executive summary and a detailed structured results section. This template will assist you with the format and information required.

    Executive Summary (Marks: 25)

    The 250-word summary should identify demographic, social and behavioural factors that are associated with routine check-up attendance in a statistically valid, clear and concise manner that can be understood by someone with minimal knowledge of epidemiology and biostatistics. You must identify a group or groups of people where a targeted campaign would be of most benefit.

    Results:

    The BRFSS:

    • A short summary of the study design of the BRFSS and a brief discussion of its limitations (no more than 250 words (Marks: 6)
    • Find a peer-reviewed paper in the literature that quantitatively investigates the determinants of routine check-up attendance. Compare the designs between the study described in that paper and BRFSS (not more than 150 words). (Marks: 4) (Note: When you search for a peer-reviewed paper, avoid literature reviews or papers that analysed BRFSS data)

    Description of the population and analysis (no more than 1350 words):

    1) By analysing the BRFSS dataset, answer the following questions:

    • In your dataset, what percentage of participants reported routine check-up attendance? (Marks: 5)
    • Create a table of routine check-up attendance and 3 demographic factors, one of which must be binary, one numerical and one multi-category categorical (either nominal or ordinal). (Marks: 15)
      • Each cell should contain the appropriate summary measure and 95% confidence interval
      • The final column in the table should contain the p-value for statistical tests of difference or independence (i.e., tests that we covered in week 6). Footnotes should be used to indicate which statistical tests were used.

    2) Examine the association between 4 social and/or behavioural factors and routine check-up attendance:

    • In an appropriate manner, present the results of analysis into the effect of four social and/or behavioural factors on routine check-up attendance. You must analyse a binary, numeric, nominal and ordinal factor. (Marks: 20)
      • For each factor you should report:
        • Variable name and data type
        • Name of measure calculated
        • Results of statistical analysis performed
        • Statistical interpretation
        • The Stata output (including visible code) e.g.

    Figure 1
    Stata output example

    • For one of the identified factors, you should explore the possibility of confounding or effect modification by sex. (Marks: 10)
      • Perform appropriate analysis
      • Present STATA output (including visible code if applicable)
      • Report the results in a table
      • Interpret your result
    • Conduct a multivariable regression and present the results, including visible Stata output, of the adjusted regression model by including the four factors you examined in your analysis of social and behavioural factors. (Marks: 10)
      • Report the results in a table.
      • Interpret your result.

    Consciousness

    The average human does not constantly consider consciousness but consciousness is constantly present for the average human. When thinking about consciousness, we cannot put a physical, scientific aspect on the theory. The conscious mind is something to be conceptualized and interpreted based on the human experience. The more consciousness is tasked to carry a physical portion of the brain, the harder it will be to interpret the mind. There will always be an issue to define exactly what the conscious is, but it is always existent. The brain does produce consciousness, but consciousness cannot produce brain functions, not anything physical. The mental states are not physical as they are a product of consciousness. If there is a shared consciousness of the individual, there is a creation of the self.

    As long as we are alive, consciousness will always receive information provided by our life experiences, then produce our thoughts and imaginations. The totally unconscious person also may be credited with memories. He also can be said to have skills, including purely mental skills such as an ability for mental arithmeticA totally unconscious person may be credited with likes and dislikes, attitudes and emotions, current desires, and current aims and purposes. He may be said to have certain traits of character and temperament. (Armstrong 56) Consciousness is similar to a storage unit, it has a multitude of items that it constantly puts away and then pulls out. Items are constantly going in and out. The gloriousness of consciousness is the level of production. We are given access to memories, access to imagination, and access to intelligence through even minimal consciousness.

    Fairytales

    Any reader of fairy tales will recognize certain patterns in the tales that are also found in world mythology. Characters are miraculously conceived, heroes and heroines descend to places that resemble mythic underworlds, and young heroes go on dangerous quests and are detained by femme fatales or challenged by monsters. Certainly, those connections between myth and fairy tale suggest an article and symbolic language common to the human psyche. On the other hand, they also suggest a conscious attempt on the part first of oral storytellers and later of the literary collectors who gathered and studied those oral tales to make use of the old sacred stories, motifs, and symbols in a still moralistic but generally secular context, with particular versions reflecting the moral and mannerly priorities of particular societies. In fact, it is difficult to differentiate between the sacred world of myth and the moralistic world of the fairy tale.

    The Elves and the Envious Neighbor
    Japan

    Once upon a time, there was a certain man, who, being overtaken by darkness among the mountains, was driven to seek shelter in the trunk of a hollow tree. In the middle of the night, a large company of elves assembled at the place; and the man, peeping out from his hiding place, was frightened out of his wits. After a while, however, the elves began to feast and drink wine, and to amuse themselves by singing and dancing, until at last the man, caught by the infection of the fun, forgot all about his fright, and crept out of his hollow tree to join in the revels.
    When the day was about to dawn, the elves said to the man, “You’re a very jolly companion, and must come out and have a dance with us again. You must make us a promise, and keep it.”

    So the elves, thinking to bind the man over to return, took a large wen that grew on his forehead and kept it in pawn; upon this, they all left the place and went home.

    The man walked off to his own house in high glee at having passed a jovial night and got rid of his wen into the bargain. So he told the story to all his friends, who congratulated him warmly on being cured of his wen. But there was a neighbor of his who was also troubled with a wen of long-standing, and, when he heard of his friend’s luck, he was smitten with envy, and went off to hunt for the hollow tree, in which, when he had found it, he passed the night.

    Elves, mistaking him for their former boon companion, were delighted to see him, and said, “You’re a good fellow to recollect your promise, and we’ll give you back your pledge.”

    So one of the elves, pulling the pawned wen out of his pocket, stuck it onto the man’s forehead, on the top of the other wen which he already had. So the envious neighbor went home weeping, with two wens instead of one.

  • Biology: The Study of Life

    1. Introduction

    Biology is the scientific study of living organisms. It focuses on how living things function, grow, reproduce, and interact with their environment.

    Biology is important because it helps us understand life, health, and the natural world.

    2. Characteristics of Living Things

    All living organisms share common characteristics:

    Growth and development

    Living things grow and change over time

    Reproduction

    They can produce offspring

    Response to stimuli

    They react to their environment

    Metabolism

    They use energy to survive

    Homeostasis

    They maintain a stable internal condition

    Nucleus controls cell activities

    Cell membrane controls what enters and leaves

    Cytoplasm where reactions happen

    Mitochondria produces energy

    Ribosomes make proteins

    6. Photosynthesis

    Photosynthesis is the process by which plants make their own food.

    Process:

    Plants use sunlight, water, and carbon dioxide to produce glucose and oxygen.

    Simple explanation:

    Sunlight + water + carbon dioxide food (glucose) + oxygen

    7. Human Body Systems

    Some important systems in the human body:

    Respiratory system helps us breathe

    Digestive system breaks down food

    Circulatory system transports blood

    Nervous system controls body activities

    8. Ecology

    Ecology is the study of how living things interact with their environment.

    Key concepts:

    Ecosystem living and non-living things interacting

    Food chain shows energy flow

    Producers plants

    Consumers animals

    9. Importance of Biology

    Biology helps us:

    Understand diseases and health

    Protect the environment

    Improve agriculture

    Develop medicine

    Conclusion

    Biology is the study of life and living organisms. It explains how life works, from the smallest cells to entire ecosystems. Understanding biology helps us live better and protect the world around us.

    Learn Basic Mandarin (English to Chinese)

    1. Introduction

    Mandarin Chinese is one of the most widely spoken languages in the world. In this lesson, learners will understand basic vocabulary, pronunciation (pinyin), and simple sentence structures. The focus is on practical daily communication.

    2. Pronunciation (Pinyin)

    Mandarin uses a system called pinyin to represent pronunciation using the Latin alphabet.

    Examples:

    n (you)

    ho (good)

    When combined:

    (N ho) = Hello

    Important note: Mandarin is a tonal language, meaning the tone of a word can change its meaning. Beginners should focus on correct pronunciation gradually.

    3. Basic Greetings

    These are commonly used expressions in daily conversation:

    Hello

    (N ho)

    Good morning

    (Zoshang ho)

    Good afternoon

    (Xiw ho)

    Goodbye

    (Zijin)

    Explanation:

    The word (ho) means good and is often used in greetings.

    4. Self Introduction

    Introducing yourself in Mandarin is simple and follows a clear structure.

    My name is Cayell

    Cayell (W jio Cayell)

    Explanation:

    (w) = I / me

    (jio) = to be called / name

    So, literally means I am called.

    5. Asking and Answering Questions

    What is your name?

    (N jio shnme mngzi?)

    Breakdown:

    (n) = you

    (jio) = called

    (shnme) = what

    (mngzi) = name

    How are you?

    (N ho ma?)

    Explanation:

    (ma) is a question particle used to turn a statement into a yes/no question.

    I am fine

    (W hn ho)

    6. Common Words and Expressions

    Yes (Sh)

    No (B)

    Thank you (Xixi)

    Sorry (Dubq)

    Usage example:

    (Xixi n) = Thank you

    7. Basic Sentence Structure

    One of the most important patterns in Mandarin is:

    Subject + (hn) + Adjective

    Example:

    I am happy

    (W hn kixn)

    Explanation:

    (hn) often means very, but in basic sentences it can simply connect subject and adjective (like am/is/are in English).

    So:

    = I am happy (not necessarily very happy)

    8. Key Differences from English

    Mandarin does not use to be (am/is/are) in the same way as English

    Word order is generally similar (Subject + Verb + Object)

    Questions are often formed by adding (ma) at the end

    9. Learning Tips

    Focus on pinyin before memorizing characters

    Practice speaking aloud to improve pronunciation

    Start with simple sentences and repeat them regularly

    Do not try to memorize everything at once; consistency is more important

    Conclusion

    Learning basic Mandarin starts with understanding simple vocabulary, pronunciation, and sentence patterns. By mastering greetings, introductions, and basic structures, learners can begin forming their own sentences and communicating effectively.
