Observational Cosmology in Macroscopic Gravity
We discuss the construction of cosmological models within the framework of
Macroscopic Gravity (MG), which is a theory that models the effects of
averaging the geometry of space-time on large scales. We find new exact
spatially homogeneous and isotropic FLRW solutions to the MG field equations,
and investigate large-scale perturbations around them. We find that any
inhomogeneous perturbations to the averaged geometry are severely restricted,
but that possible anisotropies in the correlation tensor can have dramatic
consequences for the measurement of distances. These calculations are a first
step within the MG approach toward developing averaged cosmological models to a
point where they can be used to interpret real cosmological data, and hence to
provide a working alternative to the "concordance" LCDM model.Comment: 22 page
Tourism in coastal resorts and historic areas : with a focus on Malta’s tourism
The publication is a record of the verbal presentations made during the webinar held in January 2021. They provide some very useful and interesting insights on many topics that are debated in tourism academic literature. There were nine presentations from academics and practitioners. To note in particular: (1) Prof. Andrew Smith makes a case for of UK’s seaside resorts to be developed as centres of wellbeing, considering the health benefits to people, mental health in particular, when visiting blue spaces. He also makes some reflections on Malta’s coastal resorts. (2) Leslie Vella from the Malta Tourism Authority focuses on Malta’s ‘dual nature destination’. During the peak, Malta is an island with a city, with tourists coming for the coast while engaging in urban tourism activities. In the off-peak Malta becomes a city on an island, with people engaging in cultural and urban activities, with the marine environment acting as a backdrop. He also expresses concern that climate change will have a profound effect on Malta’s receptive capacity for sun and sea tourism. (3) Prof. Alex Torpiano talks about the impacts of tourism on historic areas and also on their residents. With a growing trend of cities to open the relatively unfamiliar historic areas to tourism, more needs to be done to mitigate the negative impacts to avoid losing the very characteristics that make these areas so interesting to tourists.peer-reviewe
Keeping it Real : An Evaluation Audit of Five Years of Youth-led Program Evaluation
Youth are increasingly seen as competent in participating in research and program evaluation, two activities previously reserved for adults. This paper is a report of the findings from an evaluation audit of Stand Up! Help Out!, a participatory action after-school youth leadership development program for disadvantaged urban youth that utilized youth evaluations to develop a best practices service model. The youths’ feedback assisted providers in improving services so that youth engagement in the program was 99% (by comparison with national highs of 79%). Here, we describe an important aspect of the process of youth-led program evaluation leading to such high youth engagement: How youth interviewed each other so as to optimize the authenticity of their program evaluations and contributions to program design. Drawing from over five years of program evaluation data collected by youth, the authors report on the youths’ experiences as informants and co-researchers, consider strategies used to help youth best describe their experiences in the program, and describe implications for other settings looking to incorporate youth-led program evaluation. Youth-led program evaluation has considerable promise for helping service providers make programs more meaningful for disadvantaged youth
