“…The masses are derived through the Kaspi relation (Kaspi et al 2000) from the velocity width of Hβ broad line and continuum luminosity summarized in Akiyama et al (2000Akiyama et al ( , 2003. Overall, there is a good correlation between the two, with a scatter of ≈0.5 dex around the mean value of λ = 0.24, being consistent with other studies (e.g., Kollmeier et al 2005). This result supports our assumption that the Eddington ratio can be regarded to be constant in our sample at first-order approximation.…”

“…Since we do not examine host galaxies of AGNs at z > 0.6, it is unknown whether the BS-relation is hold at the higher redshifts or not. Studies for estimation of M BH s with Kaspi relation (Kollmeier et al 2005) show that Eddington ratios are between 0.1 -1 for AGNs at 0.3 < z < 4, and suggest that nuclear luminosity of AGNs would roughly correlate M BH s. Meanwhile, BS-relations at higher redshift are rather controversial. Shields et al (2003) show that the BS-relation of AGNs does not evolve from z ∼ 3 to 0.…”

“…The cause for the different distribution is not clear. Since it is suggested that low luminosity AGNs tend to have lower Eddington ratios with a larger scatter than high luminosity QSOs (e.g., Kollmeier et al 2005), it might be possible that the sample of Schade et al (2000) includes objects with lower Eddington ratios, while our sample does not contain such objects.…”

We study properties of the host galaxies of 15 hard X-ray selected type-2 active galactic nuclei (AGNs) at intermediate redshifts (0.05< z <0.6) detected in ASCA surveys. The absorption corrected hard X-ray luminosities L 2−10keV range from 10 42 erg s −1 to 10 45 erg s −1 . We took the R-band image of these AGNs with the University of Hawaii 2.2 m telescope. Thanks to the intrinsic obscuration of nuclear light, we can decompose the galaxies with a spheroid component and a disk component. The resulting spheroid luminosities correlate with L 2−10keV ; higher (lower) X-ray luminosity AGNs tend to reside in luminous (less luminous) spheroids. It is also found that the hosts of luminous AGNs show a large spheroid-to-disk luminosity ratio (∼1), while those of less luminous AGNs spread between 0 and 1. The correlation between L 2−10keV and spheroid luminosity indicates that the relation between mass of a supermassive black hole (SMBH) and spheroid luminosity (BS-relation) at the intermediate redshifts. BS-relation agrees with that in the local universe, if the Eddington ratio of 0.24 is adopted, which is a mean value determined from our ASCA type-1 AGN sample at similar redshifts through the broad-line width and continuum luminosity. The present study demonstrates the effectiveness of using type-2 AGNs at high redshifts to study their host properties.1 Based on observations made with the University of Hawaii 2.2 m telescope.

BackgroundThe risk of aspiration is high in stroke patients due to dysphagia/loss of swallowing. This problem can cause problems affecting the nutrition of patients. Due to the possible risk of aspiration during feeding, patient relatives are hesitant to feed their patients. Because of this fear, malnutrition and hospital readmissions may increase. It is important to evaluate the fear of aspiration risk of relatives of patients hospitalized in the neurology service. The aim of this study is to determine the views of the relatives of patients treated in the neurology service about the risk of aspiration through metaphors.MethodThis article analyzed metaphors of patients' relatives' about the risk of aspiration. The analysis uses metaphor identification and analysis. The research sample consisted of 31 patients. First of all, in the study, evaluation of the data was conducted by performing content analysis, as a result of which it was divided into metaphors and conceptual categories, and the relevant field was associated with the text (event, thought, feelings, related in speech or writing). In the reporting of research, the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist was used.ResultsIt was seen that the patients' relatives produced 31 different metaphors in response to the statement ‘Aspiration risk is like …, because it is …’ The patients' relatives mostly compared the concept of ‘fear of aspiration’ to the concept of ‘fear’ (n: 24).ConclusionsIn this study, relatives mostly described the concept of fear related to the risk of aspiration. According to this result, patients' relatives have a great fear of aspiration increasing the risk of readmission to hospital and of malnutrition. This result shows that informing patients' relatives will increase awareness and will allow them to provide informed care.Patient and Public ContributionCollaborated with patients and their relatives regarding the risk of aspiration and contributed to the planning of care for the risk of aspiration.
