Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Input: Consider Input: A recent (123)I-FP-CIT ((123)-I-N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane) SPECT study on rats suggested that a single 1 mg/kg dose of the antipsychotic haloperidol induces enough dopamine release to compete with (123)I-FP-CIT for binding to the dopamine transporter. Taking into account the far-reaching consequences of this proposition, we were interested in testing whether we could reproduce this finding using storage phosphor imaging.', 'Twenty rats were pretreated with saline or haloperidol (1 mg/kg of body weight) and then injected with (123)I-FP-CIT. Two hours after (123)I-FP-CIT injection, the rats were sacrificed and binding in the striatum, nucleus accumbens, and cerebellum (nonspecific binding) was measured.', 'In contrast to the earlier SPECT finding, acute administration of haloperidol did not induce a significant change in (123)I-FP-CIT binding ratios in the striatum and nucleus accumbens.

Input: Consider Input: To determine whether a paper-based antibiotic ordering system is an effective antibiotic stewardship measure.', 'An antibiotic order form (AOF) was introduced in July 2001 at a pediatric tertiary care hospital. Vancomycin courses prescribed before and after the AOF introduction were retrospectively reviewed based on Hospital Infection Control Practices Advisory Committee guidelines. The impact of the AOF on the appropriateness of vancomycin prescribing was evaluated in univariate and multivariable analyses that adjusted for other factors associated with appropriateness of vancomycin use. The density of vancomycin use after introduction of the AOF was also assessed.', 'Compliance with the AOF was poor (<50%) during the planned study period; therefore an additional 2 months of improved compliance (70-80%) were included. Rates of inappropriate vancomycin use increased during the study periods: 35% before AOF; 39% post-AOF; and 51% during the improved compliance period. On adjusted analysis, vancomycin utilization was significantly more inappropriate after introduction of the AOF. Vancomycin doses per 1000 patient days increased after introduction of the AOF.

Input: Consider Input: Invasive species can have devastating effects on native ecosystems and therefore impose a significant threat to human welfare. The introduction rate of invasive species has accelerated dramatically in recent times due to human activity (anthropogenic effects), with a steadily growing pool of widespread tramp species. We present an in-depth analysis of four pantropical species of Xyleborus ambrosia beetles (Xyleborus volvulus, Xyleborus perforans, Xyleborus ferrugineus, and Xyleborus affinis) with similar ecology (fungus cultivation in dead wood), reproductive biology (permanent inbreeding) and genetic system (haplodiploidy). The unique combination of reproductive traits and broad host plant usage pre-adapts these beetles for colonizing of new areas.', 'We found that all four species were broadly distributed long before human-assisted dispersal became common, and that the impact of anthropogenic effects varied among the species. For X. volvulus, X. perforans, and X. affinis there was evidence of ancient establishment in numerous regions, but also of abundant recent introductions into previously colonized areas. For X. ferrugineus, we found clear biogeographical structuring of old clades, but little evidence for recent successful introductions.
