Ecotourists appreciate nature and are willing to learn about nature and ecology. Th erefore ecotourism is often seen as a product package that supports sustainable tourism development. Th is study contributes to existing research in the fi eld of ecotourism as it investigates how travel motives and environmental concern of mountain tourists infl uences their actual demand for ecotourism. A surv...

1. When is it true? (5 points for each correct answer, -3 point for each wrong answer, 0 point for each blank) Fill in each blank with “always,” “sometimes,” or “never.” For example, • A nonsingular matrix is always invertible. • A square matrix is sometimes full-rank. • A strictly tall matrix is never onto. Here the matrix dimensions are such that each expression makes sense, but they are othe...

The idea behind boosting is to construct an accurate hypothesis from a set of hypotheses that are each guaranteed to perform slightly better than random guessing on particular distributions of data. This idea originally arose from attempts to prove the robustness of the PAC model. By robustness, we mean the notion that slight alterations to the model definitions should not result in dramaticall...

The in vitro activities of temafloxacin (A63004) and lomefloxacin (SC-47111; NY-198) were compared with those of seven other antibiotics against 146 isolates of bacterial enteric pathogens, including Campylobacter jejuni and Campylobacter coli. Ciprofloxacin was the most active drug against the Salmonella, Shigella, Yersinia, and Vibrio spp. tested. Lomefloxacin, temafloxacin, and difloxacin we...

(a) Since A is full-rank and fat, Ax = b has at least one solution. From Problem 4 in HW#4, we know that since C is full-rank and tall, 〈x, y〉C := (Cx) TCy defines a valid inner product. So the problem reduces to one of finding the least-norm solution to Ax = b w.r.t. this inner product. Clearly, the required solution will be found by projecting the zero vector on the affine subspace defined by...
