3c Activity: Presentations and Other Outputs

Goal

We will add a Quarto slide deck to the same practice project, reuse generated values and a figure in the slides, render the project, and commit the source files.

Progress: 0 / 0 steps complete.

Activity

Open the python_tmr_practice repository in Codespaces.

This should be the same repository you used for the manuscript and generated-results activities.

I opened the practice repository in Codespaces.

At the top level of the repository, create a file named slides.qmd.

Paste this starter deck into the file:

Click inside the block to select it, then copy and paste it into slides.qmd.

```{python}
#| label: setup-slides

from random import Random

import matplotlib.pyplot as plt
import pandas as pd
import statsmodels.formula.api as smf
from pandas.plotting import scatter_matrix


rng = Random(2026)

rows = []
for firm_id in range(1, 121):
    size = rng.gauss(0, 1)
    attention = rng.gauss(0, 1)
    slack = 0.35 * size + rng.gauss(0, 0.8)
    performance = (
        0.75 * attention
        + 0.25 * slack
        + 0.20 * size
        + rng.gauss(0, 1)
    )

    rows.append(
        {
            "firm_id": firm_id,
            "attention": attention,
            "slack": slack,
            "size": size,
            "performance": performance,
        }
    )

results_data = pd.DataFrame(rows)
analysis_vars = ["performance", "attention", "slack", "size"]

model = smf.ols(
    "performance ~ attention + slack + size",
    data=results_data,
).fit()

sample_size = len(results_data)
attention_coef = model.params["attention"]
attention_p = model.pvalues["attention"]
attention_coef_text = f"{attention_coef:.2f}"
attention_p_text = "< .001" if attention_p < 0.001 else f"{attention_p:.3f}"
```

## Research question

How does stakeholder attention relate to firm performance?


## Data and sample

The sample includes `{python} sample_size` simulated firm-year observations.


## Main result

Attention is positively associated with performance in the simulated data.

b = `{python} attention_coef_text`

p = `{python} attention_p_text`


## Figure

```{python}
#| label: fig-slide-scatter-matrix
#| fig-width: 6
#| fig-height: 5
#| out-width: "78%"

axes = scatter_matrix(
    results_data[analysis_vars],
    figsize=(6, 5),
    diagonal="kde",
    alpha=0.7,
)
fig = axes[0, 0].figure
fig.tight_layout()
plt.show()
```


## Takeaway

- Quarto can make manuscripts and slides from the same project.
- Generated values help keep research outputs in sync.
- Small workflow changes can reduce copy/paste errors.

Save the file.

I created slides.qmd with the starter deck.

I updated the author name or title in the slide deck.

Open _quarto.yml.

In the render list, add slides.qmd:

  render:
    - index.qmd
    - paper.qmd
    - slides.qmd

In the navigation list, add a link to the slides:

      - text: "Slides"
        href: slides.qmd

The full _quarto.yml should still include the bibliography, CSL, and HTML format settings from the manuscript activity.

I added slides.qmd to the _quarto.yml render list.

I added a Slides link to the website navigation.

Open index.qmd.

Add a link to the slide deck under ## Outputs:

- [Research Presentation](slides.qmd)

Save the file.

I linked the slide deck from index.qmd.

Render the slide deck:

quarto render slides.qmd

Then render the whole project:

quarto render

Open the rendered slide deck and look for:

the title slide;
the inline sample size;
the inline coefficient and p value;
the scatter matrix figure.

I rendered slides.qmd.

I rendered the whole project.

I found the generated values and figure in the rendered slides.

Use Source Control:

Review the changes.
Stage slides.qmd, _quarto.yml, and index.qmd.
Commit with a message such as:

Added Quarto research slides.

Push or sync the commit to GitHub.

I reviewed the slide deck and project configuration changes.

I committed the slide deck changes.

I pushed or synced the commit to GitHub.
