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: Oesophageal cancer is generally associated with late presentation and poor prognosis. Therefore palliative surgery has been largely superseded by less invasive non-surgical techniques. Once palliation is indicated, the aims of the management should be: the maintenance of oral intake, minimizing hospital stay, relief of pain, elimination of reflux and regurgitation and the prevention of aspiration.', 'This study was a review of all published English language data on the palliation of malignant dysphagia between 1994-1999. The Medline and Bids databases were searched and other references were derived from the material perused.

Example Input: Chronic stress is generally known to exacerbate the development of numerous neuropsychiatric diseases such as fear and anxiety disorders, which is at least partially due to the disinhibition of amygdala subsequent to the prolonged stress exposure. GABA receptor A (GABAAR) mediates the primary component of inhibition in brain and its activation produces two forms of inhibition: the phasic and tonic inhibition. While both of them are critically engaged in limiting the activity of amygdala, their roles in the amygdala disinhibition subsequent to chronic stress exposure are largely unknown.', 'We investigated the possible alterations of phasic and tonic GABAAR currents and their roles in the amygdala disinhibition subsequent to chronic stress. We found that both chronic immobilization and unpredictable stress led to long lasting loss of tonic GABAAR currents in the projection neurons of lateral amygdala. By contrast, the phasic GABAAR currents, as measured by the spontaneous inhibitory postsynaptic currents, were virtually unaltered. The loss of tonic inhibition varied with the duration of daily stress and the total days of stress exposure. It was prevented by pretreatment with metyrapone to block corticosterone synthesis or RU 38486, a glucocorticoid receptor antagonist, suggesting the critical involvement of glucocorticoid receptor activation. Moreover, chronic treatment with corticosterone mimicked the effect of chronic stress and reduced the tonic inhibition in lateral amygdala of control mice. The loss of tonic inhibition resulted in the impaired GABAergic gating on neuronal excitability in amygdala, which was prevented by metyrapone pretreatment.

Example Input: The aim of this study was to examine recent trends in imaging utilization in emergency departments (EDs) in the Medicare population.', "The 2002 to 2012 Medicare Part B databases were used. Imaging studies were categorized by modality. Medicare's place-of-service codes identified those studies performed in ED patients. Specialty codes identified the specialties of the interpreting physicians. Utilization rates per 1,000 Medicare beneficiaries were calculated. Trends were assessed in plain radiography (XR), CT, noncardiac ultrasound, MRI, and nuclear medicine.", 'XR and CT were the most widely used modalities in ED patients. From 2002 to 2012, the XR utilization rate per 1,000 increased from 248.7 to 320.0 (+29%), and CT increased from 57.2 to 147.9 (+159%). Utilization rates of the other modalities were much lower. Ultrasound increased from 9.5 to 21.0 (+121%), while MRI increased from 1.4 to 5.1 (+264%). Growth in these 4 modalities was continuous and did not show the flattening that has characterized the utilization trends in other places of service. Nuclear medicine use was very low and remained essentially flat. During the study period, CT accrued 91 new examinations per 1,000, followed by XR at 71 and ultrasound at 11.5. The vast majority of examinations were interpreted by radiologists.
