Week 1 Discussion: Initial Post
From Topic to Fundable Question: Does a Portable HEPA Air Cleaner in the Home Reduce Urgent Asthma Visits Among Children During Wildfire Smoke Events?
Initial Post
My topic is wildfire smoke and children's asthma, but a topic is not something a panel can fund. What I propose to carry through the term is a narrower question: in an inland county where smoke from distant fires settles for days each summer and fall, does placing a portable HEPA air cleaner in the bedroom of a child with persistent asthma reduce urgent asthma visits, meaning emergency department, urgent care and unscheduled clinic visits, during smoke events, compared with a sham cleaner that runs without its filter?
Each part of that wording was chosen with a reviewer in mind. "Portable HEPA air cleaner" names an intervention a family can actually receive. "Children with persistent asthma" defines a population at known risk; a critical review found that wildfire smoke is consistently associated with respiratory effects, with the strongest evidence for asthma exacerbations (Reid et al., 2016). "Urgent asthma visits" names an outcome that matters to families and health systems and can be counted from records, rather than a symptom score that depends on recall. "During smoke events" fixes when the effect should appear. And the sham comparison answers the obvious objection that families who receive a humming machine may change their behavior or reporting.
The question also sits in a real evidence gap. Field measurements show that portable HEPA cleaners substantially lower indoor fine particles during fire smoke (Barn et al., 2008), and a trial among children exposed to secondhand tobacco smoke found that HEPA cleaners reduced unscheduled asthma visits (Lanphear et al., 2011). What no one has shown, as far as I can find, is whether lower indoor particles during wildfire smoke translate into fewer urgent visits for children with asthma. Smoke events are episodic, homes leak differently, and families may not run the cleaner when it matters, so the step from cleaner air to fewer visits is genuinely uncertain.
I also had to decide what the question leaves out. It does not ask whether smoke harms children with asthma, which is already established, or whether cleaners lower indoor particles, which field studies have shown. It does not ask about adults, outdoor workers or clean air shelters, all worthwhile but separate questions. Narrowing the question to one intervention, one population and one outcome is what lets a single trial answer it within a five-year award, and it keeps the aims from sprawling into a program that no panel could score as one study. What would make this question unfundable? If smoke events are too rare in the county to accumulate enough visits, the study could not detect an effect. I plan to check that against several years of county smoke and visit data before going further, since the answer decides whether a trial is possible at all.
My question for the thread: when you reworded your topic as a question, which word did the most work in making it testable?

What the PHLT 8046 Week 1 instructions ask for
The opening thread asks students to propose a research question for the grant they will develop over the term. Faculty expect a question, not a topic: one that names an intervention or exposure, a population, a comparison, an outcome and a setting precisely enough that a study could answer it. Strong posts explain why each element was chosen, with a source showing the problem is real and a sentence locating the evidence gap the question would fill. They also show judgment about scope by saying what the question excludes, since a question that tries to answer everything cannot be studied in one award. Naming a risk to feasibility, and how it will be checked, shows awareness of how panels think. A closing question for classmates keeps the thread analytic. Five hundred words is a common length.
How the PHLT 8046 Week 1 example is put together
The post opens by distinguishing a topic from a question and stating the question in full. A paragraph walks through its phrases, intervention, population, outcome, timing and sham comparison, explaining what each does for a reviewer and citing a critical review of wildfire smoke and asthma. A second paragraph places the question between field studies of cleaners and indoor particles and a trial of cleaners and unscheduled visits in secondhand smoke, and explains why the step from cleaner air to fewer visits is uncertain during episodic smoke. A third paragraph lists what the question leaves out, from adults to clean air shelters, and names the main feasibility risk, too few smoke events, with a plan to check county data. A question asks classmates which word made their question testable.
Where the marks sit in the PHLT 8046 Week 1 rubric
Credit goes mainly to the precision of the question and the reasoning behind its wording. A post that announces a topic or a broad aim earns little, however important the subject. Graders look for each element of the question defended, a source establishing the problem, and a clear statement of the evidence gap. Scope judgment, saying what the study will not answer, is rewarded because it shows the author can design a feasible project. Naming a realistic threat to feasibility, and how it will be tested, demonstrates the reviewer's perspective the course aims to build. Citations should be accurate and relevant. Participation credit follows a final line that sends peers back to their own wording rather than inviting them to share topics.
Common PHLT 8046 Week 1 mistakes, and how to avoid them
Opening posts in grant courses often describe a passion rather than a question. Write your question in one sentence that names who, what intervention or exposure, compared with what, measured how and where. Then explain why you chose each word, and support the problem with one good source. Say what gap your answer would fill and what you are deliberately not asking. Name the one thing most likely to make the study unworkable and how you will check it. A fundable question for your own research interest can be shaped the same way.

Send the discussion prompt, its rubric and the research area you are considering, and an initial post built around one falsifiable question returns in 24-48h; the first costs nothing. The county, its smoke seasons and the air cleaner study form an invented scenario, so the question in your post comes from your own interests and reading.

PHLT 8046 Week 1 questions, answered
Does the Week 1 question have to be the one used for the whole proposal?
Many sections let the question change after feedback, and some expect it to narrow. The example treats its question as a working version and says so. If your course carries the Week 1 question into the aims page and budget, choose one you can live with for the term, because rewriting the question later means rewriting every section built on it.
What makes a research question fundable rather than merely interesting?
A panel funds a question whose answer would change what someone does, and whose design can actually produce that answer. Interest alone does not score. The example ties its question to decisions a county health department faces every smoke season. A post earns more when it names who would act differently on either result, including the null one, and why that action matters.
Is the smoke and asthma question drawn from real research?
The county, its alert system and the planned trial are invented for illustration. Research on indoor air filtration and childhood asthma does exist, and the post frames its gap claim as provisional because no structured search has tested it yet. Your own gap claim deserves the same caution until your search supports it, since a panel will check it against what has been published.
Where can I find a free PHLT 8046 Week 1 sample paper?
The full Week 1 post is reproduced on this page, turning wildfire smoke and children's asthma into a testable, fundable question about HEPA air cleaners and urgent asthma visits, with three references.
Why compare against a sham cleaner rather than no cleaner?
Families who receive a working machine may change other habits or report symptoms differently. A sham unit that looks and sounds the same keeps that effect equal in both groups.
