Human Factors
Approaching PVD on radar vectors for the visual approach Runway 23. Small GA aircraft on VFR and not in contact with ATC got into close proximity of our flight path. We reacted with an RA and maneuvered on a climb per TCAS instructions to clear conflict. GA aircraft was believed to be within 300 ft of vertical separation. On final approach the runway had a trash bag and other FOD; so the ground crew failed to clear the FOD from the runway causing a go around instructed by ATC. Go around executed around 700 ft AGL. [Caused by] aircraft flying VFR near complex airspace. And trash bag on runway. Followed per [company] procedures in both cases. Encourage VFR traffic to be in radar contact if flying near complex airspace.
Air carrier Captain reported reacting to an RA triggered by a light aircraft during their arrival into PVD; and then executing a go-around after noticing FOD on the runway.
