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.

[EX Q]: The present study investigated how parents and peers interact in promoting or delaying Dutch adolescents' sexual initiation and intention and focused specifically on parents as moderators of peer influence.", "Using a longitudinal design, two waves of online questionnaire data were collected among 900 Dutch adolescents (M = 13.8 years at T1), who were sexually inexperienced at baseline. At T1, participants reported on three types of perceived sexual peer norms: friends' sexual behaviors (descriptive norms), friends' sexual attitudes (injunctive norms), and experienced peer pressure to have sex. They also rated two parenting aspects at T1: the general quality of their relationship with parents and the frequency of sexuality-specific communication with their parents. Six months later, the participants reported on their experience with different sexual behaviors ranging from naked touching or caressing to intercourse and their intention to have sex in the next school year.", "Relationship quality with parents was significantly associated with both outcomes, with a higher relationship quality predicting smaller odds of sexual initiation and less intention to have sex. Two significant interaction effects showed that frequent sexual communication with parents significantly reduced the effects of sexually active friends and experienced peer pressure on adolescents' intention to have sex.

[EX Q]: To evaluate intestinal inflammatory and apoptotic processes after intestinal ischemia/reperfusion injury, modulated by pentoxifylline and hypertonic saline.', 'It was allocated into four groups (n=6), 24 male Wistar rats (200 to 250 g) and submitted to intestinal ischemia for 40 min and reperfusion for 80 min: IR (did not receive any treatment); HS group (Hypertonic Saline, 4 ml/kg-IV); PTX group (Pentoxifylline, 30 mg/kg-IV); HS+PTX group (Hypertonic Saline and Pentoxifylline). All animals were heparinized (100 U/kg). At the end of reperfusion, ileal fragments were removed and stained on hematoxylin-eosin and histochemical studies for COX-2, Bcl-2 and cleaved caspase-3.', 'The values of sO2 were higher on treated groups at 40 minutes of reperfusion (p=0.0081) and 80 minutes of reperfusion (p=0.0072). Serum lactate values were lower on treated groups after 40 minutes of reperfusion (p=0.0003) and 80 minutes of reperfusion (p=0.0098). Morphologic tissue injuries showed higher grades on IR group versus other groups: HS (p=0.0006), PTX (p=0.0433) and HS+PTX (p=0.0040). The histochemical study showed lesser expression of COX-2 (p=0.0015) and Bcl-2 (p=0.0012) on HS+PTX group. A lower expression of cleaved caspase-3 was demonstrated in PTX (p=0.0090; PTXvsIR).

[EX Q]: To determine whether macrophages in human reproductive tissues contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptor mRNA and receptor protein that can bind 125I-hCG.', 'Macrophages isolated from term pregnancy human decidua were used for LH/hCG receptor detection by in situ hybridization for receptor mRNA and immunocytochemistry for a macrophage marker, CD68, performed alone and in combination, reverse transcription-nested polymerase chain reaction, Western and ligand blotting. The LH/hCG receptor presence in macrophages in late luteal phase human endometria and corpora lutea was determined by sequential performance of in situ hybridization and immunocytochemistry.', 'The macrophages present in term pregnancy human decidua and late luteal phase human endometria and corpora lutea contain LH/hCG receptors.
