The goal of this work is to study the obscuration properties of mid-infrared (mid-IR)-selected active galactic nuclei (AGN). For that purpose, we use Wide-field Infrared Survey Explorer (WISE) sources in the Stripe 82-XMM area to identify mid-IR AGN candidates, applying the Assef et al. criteria. Stripe 82 has optical photometry approximate to 2 times deeper than any single-epoch Sloan Digital Sky Survey (SDSS) region. XMM-Newton observations cover similar to 26 deg(2). Applying the aforementioned criteria, 1946 IR AGN are selected. similar to 78 per cent have SDSS detection, while 1/3 of them are detected in X-rays, at a flux limit of similar to 5 x 10(-15) erg s(-1) cm(-2). Our final sample consists of 507 IR AGN with X-ray detection and optical spectra. Applying a r - W2 > 6 colour criterion, we find that the fraction of optically red AGN drop from 43 per cent for those sources with SDSS detection to 23 per cent for sources that also have X-ray detection. X-ray spectral fitting reveals 40 (similar to 8 per cent) X-ray absorbed AGN (N-H > 10(22) cm(-2)). Among the X-ray unabsorbed AGN, there are 70 red systems. To further investigate the absorption of these sources, we construct spectral energy distributions (SEDs) for the total IR AGN sample. SED fitting reveals that similar to 20 per cent of the optically red sources have such colours because the galaxy emission is a primary component in the optical part of the SED, even though the AGN emission is not absorbed at these wavelengths. SED fitting also confirms that 12 per cent of the X-ray unabsorbed IR AGN are optically obscured.

Background Adults spend a large proportion of their day at work. Physical activity (PA) and sedentary behaviour (SB) have been shown to vary considerably between occupations. The objective of this study is to describe occupational differences in accelerometer-measured and self-reported PA and SB for Canadian full-time workers. Data and methods Using combined data from three cycles of the nationally representative Canadian Health Measures Survey (N = 4,080), three activity groups (high, intermediate, low) were created based on a composite ranking of accelerometer-derived steps, proportion of time spent sedentary (SED%) and moderate-to-vigorous intensity physical activity (MVPA) in bouts of >= 10 minutes (MVPA(bouted)). Differences between groups were assessed for accelerometer-derived and self-reported PA and SB, and sociodemographic and clinical characteristics. Results On average, Canadians employed in full-time work were sedentary for 68.9% of their day (95% confidence interval [CI]: 68.3% to 69.6%), took 8,984 steps per day (95% CI: 8,719 to 9,249) and accumulated 79.5 minutes per week of MVPA(bouted) (95% CI: 71.1 to 87.9). Among Canadians employed in full-time work, 18.5% met the Canadian Physical Activity Guidelines. The high-activity group took significantly more steps and had a lower SED%, but spent a higher proportion of time in light-intensity PA compared with the intermediate- and low-activity groups. No differences were observed for MVPA. The low-activity group reported more recreational and active travel-related PA and leisure reading, while those in the high-activity group reported more work and domestic PA and leisure screen time. Interpretation The majority of full-time working adults are not getting adequate MVPA and spend most of their day sedentary, regardless of occupation. Findings support workplace policies to improve MVPA levels among Canadian workers and to promote awareness for the potential benefit of occupation-specific messaging around PA and SB.
