Intra-ocular straylight can cause decreased visual functioning, and it may cause diminished vision-related quality of life (VRQOL). This cross-sectional population-based study investigates the association between straylight and VRQOL in middle-aged and elderly individuals. Multivariable linear regression analyses were used to assess the association between straylight modeled continuously and cutoff at the recommended fitness-to-drive value, straylight ≥ 1.4 log(s), and VRQOL. The study showed that participants with normal straylight values, straylight ≤ 1.4 log(s), rated their VRQOL slightly better than those with high straylight values (straylight ≥ 1.4 log(s)). Furthermore, multivariable regression analysis revealed a borderline statistical significant association (p = .06) between intra-ocular straylight and self-reported VRQOL in middle-aged and elderly individuals. The association between straylight and self-reported VRQOL was not influenced by the status of the intra-ocular lens (natural vs. artificial intra-ocular lens after cataract extraction) or the number of (instrumental) activities of daily living that were reported as difficult for the elderly individuals.
Frequent claims are made for the importance of the hospitality industry, and wider tourism sector, as potential and actual creators of employment. Many of these claims emanate from industry representative and advocacy organizations, often as part of their legitimate efforts to lobby governments for favourable treatment of their sectors. Good quality universal statistical data on employment in hospitality are noticeable by their absence, although information collected by bodies such as the International Labour Organization is extensive. This paper reviews the current state of data availability on global hospitality employment (with a primary focus on commercial hospitality operations) and seeks to employ these secondary sources in investigating the question as to whether we can in fact make plausible statements about the extent of such employment. This exercise is important both to contextualizing claims made for the employment generating capacity of the hospitality industry and to shedding light on the degree of seriousness with which data might be treated in wider policy contexts. The paper concludes, with cautious optimism, that commercial hospitality is a significant global employer and that the claims made for this employment by representative and advocacy organizations are plausible if treated with circumspection.
