The Effects of Finger-Walking in Place (FWIP) on Spatial Knowledge Acquisition in Virtual Environments

Spatial knowledge, necessary for efficient navigation, comprises route knowledge (memory of landmarks along a route) and survey knowledge (overall representation like a map). Virtual environments (VEs) have been suggested as a power tool for understanding some issues associated with human navigation, such as spatial knowledge acquisition. The Finger-Walking-in-Place (FWIP) interaction technique is a locomotion technique for navigation tasks in immersive virtual environments (IVEs). The FWIP was designed to map a human’s embodied ability overlearned by natural walking for navigation, to finger-based interaction technique. Its implementation on Lemur and iPhone/iPod Touch devices was evaluated in our previous studies. In this paper, we present a comparative study of the joystick’s flying technique versus the FWIP. Our experiment results show that the FWIP results in better performance than the joystick’s flying for route knowledge acquisition in our maze navigation tasks

Social Housing and Location Choices of Immigrants in France

Our study examines the empirical links between social housing policy and location choices of immigrants in France. More specifically, we characterize the main individual and contextual determinants of the probability for immigrants to live in a HLM (habitations à loyer modéré, dwelling with a moderate rent), which is the main public housing policy in France. For that purpose, we use individual information coming from large (one-fourth) extracts of the French population censuses conducted by INSEE (Paris) in 1982, 1990, and 1999. Our estimates show that, in general, migrants live more frequently in social housing than French natives, other observables being equal. In particular, this probability is higher for migrants from Turkey, Morocco, Southeast Asia, Algeria, Tunisia and Sub-Saharan Africa (in descending order). We find also that migrants of all origins live less often in a HLM when the city has plenty of social housing and when the fraction of natives is high.social magnets, migration, social housing

Interfirm Mobility, Wages, and the Returns to Seniority and Experience in the U.S.

In this paper, we follow on the seminal work of Altonji and Shakotko (1987) and Topel (1991) and reinvestigate the returns to seniority in the U.S. These papers specify a wage function, in which workers’ wages can change through two channels: (a) returns to their seniority; and (b) returns to their labor market experience. We start from the same wage equation as in previous studies, and, following our theoretical model, we explicitly include a participation-employment equation and an interfirm mobility equation. The employment and mobility decisions define the individual’s experience and seniority. Because experience and seniority are fully endogenized, we introduce into the wage equation a summary of the workers’ entire career and past jobs. The three-equation system is estimated simultaneously using the Panel Study of Income Dynamics (PSID). For all three education groups that we study, returns to seniority are quite high, even higher than what was previously obtained by Topel. On the other hand, the returns to experience appear to be similar to those previously found in the literature.wage mobility, interfirm mobility, returns to seniority, panel data, Markov Chain, Monte Carlo methods

Sovereign wealth fund on sustainable economic growth in Nigeria

The Sovereign Wealth Fund (SWF) nations understood that having enough money in easily accessible foreign accounts would be beneficial to the government in times of fiscal crisis, currency devaluation, natural economic calamity, and even political upheaval to help cushion sustainable economic growth. Between Q1 2005 and Q4 2020, the study looked at the impact of Nigeria's sovereign wealth fund on the country's ability to sustain economic development. In order to conduct the empirical analysis, the study used the ARDL technique of analysis. In order to prevent erroneous regression results, unit root tests were performed on each of the variables. The co-integration test revealed that there is a long-term (or equilibrium) relationship between Nigeria's sovereign wealth fund and the sustainability of its economic growth. It was revealed that Nigeria's gross domestic product was significantly impacted by the Nigerian Infrastructural Fund. Last but not least, it was revealed that the stability Fund has a considerable impact on GDP in Nigeria. Future Generation Fund was also found to have a big impact. On the whole, SWF impact significantly on sustainable economic growth in Nigeria. If government wishes to maintain economic growth and improve the lives of Nigerians, it should demand and pursue effective control and monitoring of the infrastructure, future and stabilization funds
