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: To explore the role of SCF/c-Kit signaling in the invasion of bladder cancer T24 cells.', 'Western blotting was used to detect the expression of c-Kit and PI3K pathway activation stimulated by stem cell factor (SCF) in T24 cells. The invasiveness of T24 cells before and after SCF stimulation and Wortmannin (aspecific PI3K inhibitor) treatment was evaluated using Transwell invasion assay (direct and indirect counting methods).', 'T24 cells expressed c-Kit protein and showed obvious Akt phosphorylation after stimulation with SCF (1 ng/ml) for 24 h. Compared to the control group, SCF stimulation (1 ng/ml) caused a greater number of T24 cells to migrate through the polycarbonate film (P<0.01), and this effect was blocked by the application of Wortmannin before the stimulation.

Example Input: To explore the protective effect of the Phyllanthus Urinaria (PU) extract on the N-cadherin expression in the testicular tissues disrupted by nitrogen mustard (HN2) in vivo.', 'HN2 was intraperitoneally injected into male KM mice at the dose of 5 mg/kg to make reproductive toxicity models, and at the same time PU was administered for intervention at the dose of 125 mg/kg, 250 mg/kg and 500 mg/kg. N-cadherin distribution, mRNA and protein expression in the testicular tissues were detected by immunohistochemistry, RT-PCR and Western blotting.', 'N-cadherin was mainly distributed in the membrane and cytoplasm of Sertoli cells at the basement of seminiferous epithelia, Leydig cells and peritubular cells, scarcely expressed in the basement of seminiferous epithelia and peritubular cells after HN2 administration. The expressions of mRNA and proteins of N-cadherin were significantly elevated with the increased dose of PU (P < 0.01). Compared with the normal control, the distribution and expression of N-cadherin showed no significant differences in either the high-dose PU group or the HN2 with high-dose PU intervention group (P > 0.05).
