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: Stigma has been suggested as a possible contributor to the high rates of treatment attrition in substance-dependent individuals, but no published empirical studies have examined this association.', 'The present paper assessed the relationship between baseline stigma variables and length of treatment stay in a sample of patients in a residential addictions treatment unit.', 'The relationship between baseline stigma variables (self-stigma, enacted stigma, and shame) and length of stay for participants (n=103) in a residential addictions treatment unit was examined.', 'Higher self-stigma predicted longer stay in residential addictions treatment, even after controlling for age, marital status, race, overall mental health, social support, enacted stigma, and internalized shame. However, other stigma variables (i.e. internalized shame, stigma-related rejection) did not reliably predict length of treatment stay.

Example Input: Studies have reported effects of prenatal marijuana exposure (PME) on cognitive and behavioral outcomes. An earlier publication from this study found that PME predicted early onset of marijuana use and frequency of marijuana use at age 14. No study has reported the effects of PME on marijuana use in young adulthood. This is a developmental period when substance use peaks, and by which, initiation of substance use has largely occurred.', 'Subjects were from a longitudinal cohort. Women were interviewed initially in their fourth prenatal month and women and their offspring were followed through 22 years. Significant covariates of offspring marijuana use at 22 years were identified and controlled for using ordinal logistic regression.', 'PME predicted marijuana use in the offspring at 22 years after controlling for significant covariates. Prenatal alcohol exposure, offspring race, gender, and age were also significant predictors, but family history of substance abuse or disorder, and sociodemographic and psychological characteristics of the mother and offspring were not. This association was not moderated by gender or race.

Example Input: D-lactate is the dextrorotatory form of L-lactate. L-lactate is the isomer routinely tested in clinical practice to assess cell hypoxemia. D-lactate has been recently proposed as a specific marker of gut ischemia-reperfusion (IR), particularly after surgery for ruptured aortic aneurysms. We sought to assess D-lactate as a reliable marker of gut IR in a rat model of supraceliac aortic clamping.', 'Prospective, randomized trial.', 'Animal research center.', 'Male Wistar rats.', 'After general anesthesia, rats were randomized into two groups (n = 8 in each). The IR group underwent a laparotomy, aortic clamping for 40 mins, and 1 hr of reperfusion. The control group underwent the same procedure, except for aortic clamping.', 'The following variables were tested after 1 hr of reperfusion (IR group) or after the equivalent time (control group): 1) tissue and cell insult via ileum morphometry and electron microscopy, serum glutamic transaminases (serum glutamic-oxaloacetic transaminase and serum glutamic-pyruvic transaminase), pH, and L-lactate; 2) systemic inflammatory response via tumor necrosis factor-alpha; and 3) D-lactate levels. After IR, mucous membrane thickness and villi height decreased significantly, respectively by 30% and 45%, and electron-microscopic examination showed typical IR mucous membrane cell insult. IR also caused lactic acidosis (pH = 7.16 +/- 0.05 vs. 7.31 +/- 0.02, p < .01; L-lactate = 7.1 +/- 1.6 vs. 1.6 +/- 0.4 mmol/L, p = .001) and increased blood levels of transaminases. Concurrently, the inflammatory response was characterized by an increase in tumor necrosis factor-alpha (213 +/- 129 vs. 47 +/- 32 pg/mL, p < .05). However, blood levels of D-lactate never increased after IR.
