Anthropogenic Space Weather
Anthropogenic effects on the space environment started in the late 19th
century and reached their peak in the 1960s when high-altitude nuclear
explosions were carried out by the USA and the Soviet Union. These explosions
created artificial radiation belts near Earth that resulted in major damages to
several satellites. Another, unexpected impact of the high-altitude nuclear
tests was the electromagnetic pulse (EMP) that can have devastating effects
over a large geographic area (as large as the continental United States). Other
anthropogenic impacts on the space environment include chemical release ex-
periments, high-frequency wave heating of the ionosphere and the interaction of
VLF waves with the radiation belts. This paper reviews the fundamental physical
process behind these phenomena and discusses the observations of their impacts.Comment: 71 pages, 35 figure
Scaling anomaly in cosmic string background
We show that the classical scale symmetry of a particle moving in cosmic
string background is broken upon inequivalent quantization of the classical
system, leading to anomaly. The consequence of this anomaly is the formation of
single bound state in the coupling interval \gamma\in(-1,1). The inequivalent
quantization is characterized by a 1-parameter family of self-adjoint extension
parameter \omega. It has been conjectured that the formation of loosely bound
state in cosmic string background may lead to the so called anomalous
scattering cross section for the particles, which is usually seen in molecular
physics.Comment: 4 pages,1 figur
How was the weekend? how the social context underlies weekend effects in happiness and other emotions for us workers
In this paper we estimate the size of weekend effects for seven emotions and then explore their main determinants for the working population in the United States, using the Gallup/ Healthways US Daily Poll 2008-2012. We first find that weekend effects exist for all emotions, and that these effects are not explained by sample selection bias. Full-time workers have larger weekend effects than do part-time workers. We then explore the sources of weekend effects and find that workplace trust and workplace social relations, combined with differences in social time spent with family and friends, together almost fully explain the weekend effects for happiness, laughter, enjoyment and sadness, for both full-time and part-time workers, with significant but smaller proportions explained for the remaining three emotions-worry, anger and stress. Finally, we show that workplace trust and social relations significantly improve emotions and life evaluations on both weekends and weekdays for all workers. ©2015 Helliwell, Wang.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.1

How Durable are Social Norms? Immigrant Trust and Generosity in 132 Countries
This paper estimates the global prevalence of social trust and generosity among immigrants. We combine individual and national level data from immigrants and nativeborn respondents in more than 130 countries, using seven waves of the Gallup World Poll (2005–2012). We find that migrants tend to make social trust assessments that mainly reflect conditions in the country where they now live, but they also reveal a significant influence from their countries of origin. The latter effect is one-third as important as the effect of local conditions. We also find that the altruistic behavior of migrants, as measured by the frequency of their donations in their new countries, is strongly determined by social norms in their new countries, while also retaining some effect of the levels of generosity found in their birth countries. To show that the durability of social norms is not simply due to a failure to recognize new circumstances, we demonstrate that there are no footprint effects for immigrants’ confidence in political institutions. Taken together, these findings support the notion that social norms are deeply rooted in long-standing cultures, yet are nonetheless subject to adaptation when there are major changes in the surrounding circumstances and environment. © 2015, Springer Science+Business Media Dordrecht.1
How universal is happiness?
HOW UNIVERSAL IS HAPPINESS? There is a longstanding discussion on whether happiness is culturally relative or not. The following questions are addressed in that context: 1) Do we all assess how much we like our life? 2) Do we appraise our life on the same grounds? 3) Are the conditions for happiness similar for all of us? 4) Are the consequences of happiness similar in all cultures? 5) Do we all seek happiness? 6) Do we seek happiness in similar ways? 7) Do we enjoy life about equally much? The available data suggest that all humans tend to assess how much they like their life.The evaluation draws on affective experience, which is linked to gratification of universalhuman needs and on cognitive comparison which is framed by cultural standards of the good life.The overall appraisal seems to depend more on the former, than on the latter source ofinformation. Conditions for happiness appear to be quite similar across the world and so arethe consequences of enjoying life or not. There is more cultural variation in the valuation ofhappiness and in beliefs about conditions for happiness. The greatest variation is found in how happy people are
Social capital and the status externality
This paper investigates how the presence of social capital affects the externality arising from status-seeking preference as a parable for inefficient antagonistic behavior. It is assumed that the stock of social capital accumulates through the strategic interaction among rational, infinitely-lived, individuals of a finite number. Using a differential game, we show that there are two types of Markov perfect equilibrium strategies, of which one leads a society to zero social capital, while the other leads to the satiation level of social capital. When there is an unstable interior steady state, there is a threshold: with any initial stock of social capital above (below) that, society is able to build social capital (correspondingly, get stuck in a poverty trap of null social capital). In the latter case, the intervention of governments is called upon, because social welfare in the poverty trap is less than that in the social capital-rich society. JEL classification: C72; D91; Z1
