Does Money Buy Immigrant Happiness?

The relationship between income and happiness for international immigrants has been relatively unexplored. A handful of cross-sectional studies has shown that income and happiness are positively correlated after migration, and that wealthier immigrants are more satisfied with their post-migration lives than are their less privileged peers. What is unclear is if the link between income and happiness remains positive as immigrants assimilate to life in a new country. This question is the focus of our study. Using longitudinal data from over 10,000 immigrants tracked up to 30 years in the German Socio-Economic Panel Survey, we set out to provide some insight into the long-term relationship between immigrants’ self-reported life satisfaction and the level of their income in its absolute form. Longitudinal analyses revealed that immigrants who experienced increases in income over time reported greater satisfaction with life and that the income-happiness link remained relatively stable over time. The effect of absolute income on immigrants’ happiness was, nevertheless, small. We also observed that country of origin played an important role in the post-migration association between income and happiness. Income was a stronger predictor of the life satisfaction of immigrants from poorer origins than it was for their wealthier counterparts.

Loneliness and social behaviours in a virtual social environment

Feeling lonely motivates people to reconnect with others, but it can also trigger a vicious cycle of cognitions and behaviours that reinforces their loneliness. In this study, we examined the behavioural consequences of loneliness in a virtual social environment. A total of 176 participants navigated a character (protagonist) through a two-dimensional browser game and rated the character's loneliness multiple times during the game. In the first part of the game, another character is introduced as the protagonist's spouse. At one point, the spouse leaves for an undetermined period of time but later returns. Immediately before this separation, higher ascribed loneliness of the protagonist was associated with more frequent interactions with the spouse. After the reunion, however, higher ascribed loneliness was associated with less frequent interactions with the spouse. Ascribed loneliness was not significantly related to the frequency of interactions with others nor to the frequency of solitary activities. These patterns held after controlling for ascribed positive affect. Participants' levels of loneliness were related to the level of ascribed loneliness only when the spouse was present but not when the spouse was absent. In sum, these findings suggest that the conditions that trigger the vicious cycle of loneliness are person- and situation-specific.     

Dislocations and cracks at Vickers indentations in (0 0 0 1) GaN single crystals

Single-crystal (0 0 0 1) GaN samples have been deformed with a Vickers indenter at room temperature using loads in the range from 0.02 to 4.90 N. Dislocations and cracks at the indentations were examined by means of scanning electron microscopy, cathodoluminescence, light microscopy and transmission electron microscopy. Geometrical relations could be found between the dislocation arrangement, cracks and the orientation of the indenter. The orientation of the indenter has only a slight effect on the dislocation pattern, but the crack system is predominantly determined by the symmetry and the orientation of the indenter.
