TL;DR: In this paper, the horizontal and vertical hole mobility of amorphous spin-coated electroluminescent conjugated films are studied. And the authors found that the horizontal mobility is about four orders of magnitude larger than the vertical mobility.
Abstract: The horizontal and vertical hole mobility of amorphous spin-coated electroluminescent conjugated films are studied. It is found that the horizontal mobility is about four orders of magnitude larger than the vertical mobility. The horizontal mobility increases daily with the aging of the polymer solution from which the film is spun. Low temperature and photoluminescence study reveal that the giant mobility anisotropy is a result of the alignment of the aggregates, formed during aging, by the centrifugal force of the spin.

TL;DR: In three research projects on intra-urban mobility in Omaha over a period of some twenty years, the secular trends and the relation of mobility to other social phenomena in the city were investigated.
Abstract: In three research projects on intra-urban mobility in Omaha over a period of some twenty years, the secular trends and the relation of mobility to other social phenomena in the city were investigated. The highest rate of horizontal mobility was found in the order, deteriorated areas; but, as the population movel toward the fringe of the city, more families moved into dwellings which they owned, which means an incrreasing rate of vertical mobility. This condition contributed to greater stability, less child dependency, fewer cases of old age relief, and less habitual juvenile delinquency. On the other hand, high rates of horizontal mobility were found in areas of instability, unrest, dependency, and crime.

TL;DR: In this article, the authors investigated energy use due to vertical mobility in the context of Asia's diverging cities and proposed a methodology to calculate energy consumption of lifts, based on a detailed review of literature, codes of practice, and 3D city models.
Abstract: Sustainable development of cities and the overall efficiency of urban infrastructure have emerged as central issues in policy consideration. Consequently, investigating the influence of urban physical form on resource use is critical. This paper investigates energy use due to vertical mobility in the context of Asia’s diverging cities. Micro mobility of citizens’ movement in the vertical direction has a distinct impact on the total energy consumption of a city or urban block. The objective of this research is to analyse the impact of different urban morphologies on vertical mobility—from buildings to urban blocks. A methodology is proposed to calculate energy consumption of lifts, based on a detailed review of literature, codes of practice, the International Organisation for Standardisation (ISO)/DIS 25745-1 standard and 3D city models. Furthermore, a tool is developed and applied in 20 typical urban blocks in four cities: Kuwait, Abu Dhabi, Hong Kong and Singapore. The average annual specific energy consumption of lifts varies significantly across the samples. A comparative analysis of all the morphologies across these cities help to understand the impact of building forms, usage, and a number of further parameters on the energy consumption for vertical mobility.

TL;DR: The potential of peer-to-peer for vertical mobility management is examined and an attempt to exploit its benefits by proposing novel horizontal mobility management schemes is proposed.
Abstract: With the increasing number of wireless devices, the importance of mobility management in future mobile networks is growing. In addition, the number of access technologies available to those wireless devices is more diversified, leading to further heterogeneity and the need for convergence of mobility management solutions. Furthermore, traditional mobility management solutions, which are based on client/server paradigms, suffer from the shortcoming of such centralized solutions (single point of failure, congestion, bottlenecks). With the initial success of peer-to-peer for file sharing applications, and based on our previous attempt to exploit its benefits by proposing novel horizontal mobility management schemes, we examine in this paper the potential of peer-to-peer for vertical mobility management. We also perform extensive simulations to quantify the performance of our proposed peer-to-peer vertical mobility management scheme.

TL;DR: In this article, the authors argue that juridical tools, such as the network contract within the Alpine farming system, can emplace migrants and enhance their social mobility, and question the extent to which mobility can affect the multiple and varying migration projects.
Abstract: ABSTRACT In the past twenty years a renewed trend of migration has flown into the Italian Alps, inverting the out-migration trend. New mountain dwellers, a heterogeneous population ranging from former urban residents who chose to inhabit highlands, to asylum seekers forced into a highland life while waiting for their documents, have adjusted to the socio-ecological environment which imposes mobility. The contribution analyses in the first place the twofold mobility of the mountain dwellers, vertical in altitude and latitude, and stresses, on the side, the inequalities and exploitation at the basis of the latitudinal mobility and, on the other hand, the mobility power and capital migrants agentively play in such regime of mobility. Questioning the extent to which mobility can affect the multiple and varying migration projects, the contribution argues that juridical tools, such as the network contract within the Alpine farming system, can emplace migrants and enhance their social mobility.
