TL;DR: In this paper, Harting et al. identified two types of teacher mobility: horizontal mobility and vertical mobility, referring to the movement of educators from one district to another and advancement in the position status hierarchy.
Abstract: Most studies of teacher mobility are descriptive studies with little attempt to state and test statistical hypotheses. Charters states that, “The career patterns of American teachers are almost exclusively matters of common knowledge rather than of accurate statistical description.”1. The writer is indebted to Roger Harting for providing the data on the test population. Previous studies have identified two types of teacher mobility: (1) horizontal mobility, referring to the movement of educators from one district to another, and (2) vertical mobility, which involves advancement in the position status hierarchy. This investigation was limited to studying the underlying characteristics of horizontal mobility and attempting to develop a means of measuring it. The emphasis on measuring teacher mobility is motivated by an interest in testing research hypotheses concerning the mobility of various types of educators.

TL;DR: In this paper, the authors used the cohort approach to study the structural change of the workforce in the industrial and agricultural sectors of the German economy and found that the entry of younger people into the tertiary sector was relatively high until the 1950s and went along with an increasing exit mobility during the employment life.

TL;DR: The only study of Cuban social organization with any claim to comprehensiveness is Lowry Nelson's "Rural Cuba", 1950 as discussed by the authors, which suggests that although lower, middle and upper classes may be distinguished according to the usual objective criteria, the subjective evaluations of Cubans pointed to only two classes, upper and lower.
Abstract: The only study of Cuban social organization with any claim to comprehensiveness is Lowry Nelson's "Rural Cuba", 1950. Nelson suggests that although lower, middle and upper classes may be distinguished according to the usual objective criteria, the subjective evaluations of Cubans pointed to only two classes, upper and lower. While making it clear that Cuban society was far from rigid and its two classes by no means homogeneous, Nelson (1950:147) discusses vertical mobility and the dynamics of interclass relations only with reference to the labor movement. The most striking aspects of this problem belonged in fact to the urban scene and thus fell outside the scope of his study. Nelson also omitted discussion of the paternalistic concept of government as a factor in the definition of classes; this also is most significant in urban contexts.

TL;DR: This dissertation proposes an Overlay Network Controller-centric (ONC) horizontal model mobility management, which operates for mobile nodes behind NAT devices and compares the proposed ONC-centric horizontal mobility management with the existing mobility management solutions with respect to advantages and layer 3 handover latency.
Abstract: MIPv4 and MIPv6 protocols, which are based on the vertical mobility management model, are network layer functions providing pre-call and mid-call mobility management for mobile nodes. The presence of non-standardized Network Address Translation (NAT) devices and widespread use of private addresses cause NAT traversal issues when a mobile node, which operates with a vertical model of network functions, changes its private IP address during a session. The Software-Defined Networking (SDN) raises the horizontal model, where the network functions are integrated and controlled over control plane. In this dissertation, we propose an Overlay Network Controller-centric (ONC) horizontal model mobility management, which operates for mobile nodes behind NAT devices. The proposed ONC-centric horizontal model mobility management is an early adaptation of the horizontal model of network functions on the control layer, which has the combined functions of NAT management and mobility management. Also, the proposed ONC-centric horizontal model mobility management guarantees an easier way to handle the NAT management and mobility management together. Finally, this paper compares the proposed ONC-centric horizontal mobility management with the existing mobility management solutions with respect to advantages and layer 3 handover latency.
