Rather than taking a variable-oriented approach, the study here extends Ragin's (1999) perspective on studying conjunctive paths or "causal recipes" for a limited number of cases (usually n<30) to the study of such paths in a large number of cases (n>300 - or, in the study here, n>30,000). The aim here is to provide a primer in theory and practice of qualitative comparative analysis (QCA) a method that goes beyond considering the net contributions of individual variables in influencing a dependent variable. The study aims to describe alternative conjunctive paths (estimated algorithms using Boolean algebra and set theory) that associate with a given outcome. The "outcome condition" being modeled (predicted) in the study are cases (travelers) who complete more than 24 airline trips for personal reasons annually; the label "extreme" or "X" air travelers identifies these cases. Though small in share of numbers (.2%) of Americans, X air travelers are mighty in share (7%) of air-trips for personal reasons. The study finds that completing a university/college degree is a necessary, but not sufficient, simple antecedent condition that identifies X air travelers; the conjunction of completing college and very frequent vacation travel is a sufficient, but not necessary, complex antecedent condition for identifying X air travelers. The approach can be useful in estimating conjunctive conditions leading to specific actions by consumers and executives.

Question 31

Do potassium channel activators such as nicorandil have any benefit in

the treatment of a diabetic patient with cardiovascular complications?

Question 32

Is a dosage of 2.5 mg/day of methyltestosterone, as a component in

some multivitamin formulae, safe to give to diabetics or will it make the

diabetes more difficult to control (see also Chapter 5, question 5)?

Question 33

How does diabetes mellitus cause atherosclerosis?

Question 34

How does diabetes cause renal damage, especially diabetic nephropathy

with the presence of microalbuminuria?

Question 35

Type 1 diabetes causes nephropathy in 40% of cases and type 2 causes it

in 20% of cases but the most common cause of nephropathy we see is

type 2, why?

Question 36

Why is intractable vomiting seen in diabetes mellitus and how can it be

managed?

Question 39

Why is there abdominal pain in diabetic ketoacidosis?

Grades of ketonuria are sometimes mentioned. I have not been able to

locate a detailed description in textbooks and would be grateful if you

could what?
