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.

Example 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.

Example Input: To investigate if diabetic patients without diabetic retinopathy despite long disease duration have different human leukocyte antigen (HLA) status vs those with an early onset of retinopathy.', 'Retrospective, nonrandomized, masked comparative study. Type 1 diabetic patients with a disease onset before age 30 were recruited to the study. The study population consisted of two groups of diabetic patients: those with normal retinopathy course (retinopathy developed during the first 20 years of diabetes onset) (23 patients) and those with postponed retinopathy (no obvious retinopathy in spite of passing 20 years of diabetes) (19 patients). These groups were matched with regard to level of glycemic control, blood pressure, and lipid profile. A group of 23 healthy patients served as controls. HLA-DQB1 typing of blood samples was done using a polymerase chain reaction with sequence-specific primer (PCR-SSP) method.', 'HLA-DQB1*0201/HLA-DQB1*0501 and HLA-DQB1*0201/HLA-DQB1*0504 haplotypes were more common among type 1 diabetic patients with normal retinopathy course than those with postponed retinopathy (26.1% vs 0.0%; p=0.019). HLA-DQB1*0301 and HLA-DQB1*0304 were less common among those diabetic patients with normal retinopathy course than those with a postponed retinopathy (63.2% vs 34.8%; p=0.067).

Example Input: To investigate the effect of patellar taping on the amplitude of electromyographic activity (EMG) of vasti activation in subjects with and without patellofemoral pain (PFP).', 'Ten participants with PFP and 12 asymptomatic controls were recruited to the study. The study was designed as a randomised crossover trial. Participants completed a stair stepping task. Three experimental conditions were assessed: no tape, therapeutic medially directed tape, and placebo vertically directed tape. The main outcome measure was the EMG amplitude of the vastus medialis obliquus and vastus lateralis during the concentric phase of stair stepping.', 'The application of medially directed therapeutic tape significantly decreased pain in subjects with PFP. However, application of tape over the patella (therapeutic or placebo) did not alter the amplitude of vasti EMG when either the PFP or control participants completed the concentric stair stepping task.
