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.

[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.

[Q]: A common variant of the IGF-I gene has been shown to be associated with cardiovascular disease in adulthood. The objective of this study was to examine whether this variant of the IGF-I gene is associated with blood pressure and left heart dimensions in early childhood.', 'This study was embedded in the Generation R Study, a population-based prospective cohort study from foetal life onwards. IGF-I promoter region was genotyped in DNA obtained from cord blood. Blood pressure (systolic and diastolic) and echocardiography (left ventricular mass, left atrial diameter and aortic root diameter) measurements were performed at the age of 2 years. Analyses were performed in 538 subjects.', 'Eight alleles of the IGF-I promoter region were identified. In total, 43% of the subjects were homozygous for the 192 bp allele (wild type), 46% were heterozygous and 11% were non-carriers. Significantly lower systolic and diastolic blood pressures were found in non-carrier subjects (difference compared with homozygous subjects: -4.4 (95% confidence interval (CI) -7.8 to -1.1) mmHg and -3.5 (95% CI: -6.9 to -0.1) mm respectively). No significant differences were found for left heart dimensions at the age of 2 years. No association was found when we used a previously proposed alternative classification of the IGF-I gene.

[Q]: We investigated the pathway of autophagy signaling linked to sarcopenia of mice.', 'Young adult (3-month) and aged (24- month) C57BL/6J mice were used. Using real-time PCR, Western blotting, and immunohistochemical microscopy, we evaluated the amounts of p62/SQSTM1, LC3, and Beclin-1 in the quadriceps muscle change with aging in mice.', 'Marked fiber atrophy (30%) and many fibers with central nuclei were observed in the aged mice. Western blotting using homogenate of the cytosolic fraction clearly showed that the amounts of p62/SQSTM1 and Beclin-1 proteins were significantly increased in the aged skeletal muscle. The amounts of these proteins in both nuclear and membrane fractions did not change significantly with age. Immunofluorescence labeling indicated that aged mice more frequently possessed p62/SQSTM1-positive fibers in the cytosol in quadriceps muscle than young ones (aged: 14% vs. young: 1%). In aged muscle, p62/SQSTM1-positive fibers were significantly smaller than the surrounding p62/SQSTM1-negative fibers. Aging did not elicit significant changes in the mRNA levels of p62/SQSTM1 and Beclin-1, but decreased LC3 mRNA level. In aged muscle, the location of p62/SQSTM1 immunoreactivity was similar to that of Beclin-1 protein, but not LC3.
