Predicting the relativistic periastron advance of a binary without curving spacetime

Relativistic Newtonian Dynamics, the simple model used previously for predicting accurately the anomalous precession of Mercury, is now applied to predict the periastron advance of a binary. The classical treatment of a binary as a two-body problem is modified to account for the influence of the gravitational potential on spacetime. Without curving spacetime, the model predicts the identical equation for the relativistic periastron advance as the post-Newtonian approximation of general relativity formalism thereby providing further substantiation of this model.Comment: 6 pages, 2 figure

World Heritage List: Does it Make Sense?

The UNESCO World Heritage List contains the 900 most treasured Sites of humanity’s culture and landscapes. The World Heritage List is beneficial where heritage sites are undetected, disregarded by national decision-makers, not commercially exploitable, and where national financial resources, political control and technical knowledge for conservation are inadequate. Alternatives such as the market and reliance on national conservation list are more beneficial where the cultural and natural sites are already popular, markets work well, and where inclusion in the List does not raise the destruction potential by excessive tourism, and in times of war or by terrorists.global public good, World Heritage, cultural certificates, monuments, UNESCO

Imbalance of World Heritage List: did the UNESCO strategy work?

The official intention of the UNESCO World Heritage List is to protect the global heritage. However, the imbalance of the distribution of Sites according to countries and continents is striking. Consequently, the World Heritage Committee launched the Global Strategy for a Balanced, Representative and Credible World Heritage List in 1994. To date, there have not been any empirical analyses conducted to study the impact of this strategy. This paper shows that the imbalance did not decrease and perhaps increased over time, thus reflecting the inability of the Global Strategy to achieve a more balanced distribution of Sites.UNESCO, international organizations, international political economy, global public goods, world heritage

Pay as you Go: A New Proposal for Museum Pricing

Museums have many different goals beyond efficiency such as social equity, financial revenue, attracting donors and gaining international, regional or local prestige. Various pricing schemes are being discussed with the aim of reaching these goals. The classical ones are entry prices and free entry. The museum club solution or exit donations allow for various additional goals. Each scheme has clear advantages and disadvantages. We propose an innovative pricing instrument: Exit prices, which are charged according to the time spent in a museum. This scheme has a number of notable advantages, in particular the better choice available to the visitors, which increases their satisfaction.prices, museums, culture, donations, homo oeconomicus
