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: Arthritis and valvular carditis coexist in several human rheumatic diseases, including systemic lupus erythematosus, rheumatic fever, and rheumatoid arthritis. T cell receptor-transgenic K/BxN mice develop spontaneous autoantibody-associated arthritis and valvular carditis. The common Fc receptor γ (FcRγ) signaling chain is required for carditis to develop in K/BxN mice. FcRγ pairs with numerous receptors in a variety of cells. The aim of this study was to identify the FcRγ-associated receptors and Fcγ receptor (FcγR)-expressing cells that mediate valvular carditis in this model.', 'We bred K/BxN mice lacking the genes that encode activating Fcγ receptors (FcγRI, FcγRIII, and FcγRIV), and we assessed these mice for valvular carditis. We similarly evaluated complement component C3-deficient K/BxN mice. Immunohistochemistry, bone marrow transplantation, and macrophage depletion were used to define the key FcRγ-expressing cell type.', 'Genetic deficiency of only one of the activating Fcγ receptors did not prevent carditis, whereas deficiency of all 3 activating Fcγ receptors did. Further analysis demonstrated that FcγRIII and FcγRIV were the key drivers of valve inflammation; FcγRI was dispensable. C3 was not required. FcRγ expression by radioresistant cells was critical for valvular carditis to develop, and further analysis indicated that macrophages were the key candidate FcγR-expressing effectors of carditis.

Example Input: Although the majority of evidence does not support association between Helicobacter pylori infection and ischaemic heart disease, the nature of this relationship may differ when virulence of the infecting strains are examined.', 'The prevalence of IgG antibody evidence of infection with CagA positive stains of H. pylori was investigated in stored plasma samples from 259 cases of myocardial infarction (aged 25-70 years, 74 males) and 259 population based controls from the same area in Northern Ireland. Two-hundred and seventy (52.1%) subjects were seropositive for anti-CagA IgG. CagA seropositivity was more common in cases than in controls: 56.4 vs 47.9%, odds ratio for seropositivity in cases (95% CI) 1.41 (1.00, 1.99). Substantial attenuation of this relationship occurred on adjustment for age, sex, number of siblings, smoking and measures of socio-economic status: odds ratio (95% CI) 1.16 (0.79, 1.70). A similar pattern was seen for seropositivity for all H. pylori strains.

Example Input: To review the publication fate of abstracts presented at dental conferences and investigate the association between full publication proportion (FPP) and abstract characteristics, conference characteristics, and methodological quality of primary studies.', 'PubMed, EMBASE, and Google Scholar were searched up to November 2014 for studies that reported at least one FPP of abstracts presented at dental conferences, with a follow-up length of no less than 48\xa0months.', 'Sixteen studies involving 10,365 abstracts presented at 52 conferences were included. The pooled FPP was 29.62% (95% confidence interval: 22.90%, 36.81%) for all presented abstracts and 51.97% (95% confidence interval: 43.19%, 60.70%) for randomized controlled trial abstracts. Abstract characteristics significantly associated with higher FPP included reporting of statistical analysis (P\xa0<\xa00.001), oral presentation (P\xa0<\xa00.001), basic science research (P\xa0=\xa00.047), and reporting of financial support (P\xa0=\xa00.009). Abstracts with positive (P\xa0=\xa00.29) or statistically significant results (P\xa0=\xa00.33) were not published more often than negative or nonsignificant results, respectively. In multivariable meta-regression analysis, conferences held in Asia (P\xa0<\xa00.001) and at a continental rather than national level (P\xa0<\xa00.001) were significantly associated with higher FPP.
