Income Mobility in Old Age in Britain and Germany

The increases in human longevity in recent decades and the trends for early retirement have posed new challenges for policy makers, and require a holistic understanding of the processes that influence the economic resources of older people. This paper contributes to this knowledge by examining the income mobility experienced by older people living in Britain and Germany during the 1990s, and by identifying personal attributes and life-course events that influenced its direction and likelihood. The analysis uses the British Household Panel Survey (BHPS) and the German Socio-Economic Panel (SOEP) panel data. The comparative perspective yields insights about the different income experience of older people in the two markedly different welfare regimes. Results show that old-age income mobility is more pronounced in Britain than in Germany, and that in both countries its occurrence is particularly associated with changes in living arrangements, in the employment status of the co-resident family members and with widowhood among women. Unemployment during working life is also associated with significant negative later life income mobility. Among those on low incomes, a high share of income from an earnings-related pension had a significant and positive effect in both countries. One policy implication is the need to strengthen the social safety net, to safeguard against downward income mobility in old age, particularly among widows. Policy incentives are required to encourage flexible living arrangements in old age, as well as a greater protection from unemployment during working life, more so in Germany than in Britain.income mobility, old age, pensions, Britain and Germany

Similarities Between Classical Timelike Geodesics in a Naked Reissner-Nordstrom Singularity Background and the Behaviour of Electrons in Quantum Theory

It is generally assumed that naked singularities must be physically excluded, as they could otherwise introduce unpredictable influences in their future null cones. Considering geodesics for a naked Reissner-Nordstrom singularity, it is found that the singularity is effectively clothed by its repulsive nature. Regarding electron as naked singularity, the size of the clothed singularity (electron) turns out to be classical electro-magnetic radius of the electron, to an observer falling freely from infinity, initially at rest. The size shrinks for an observer falling freely from infinity, with a positive initial velocity. For geodetic parameters corresponding to negative energy there are trapped geodesics. The similarity of this picture with that arising in the Quantum Theory is discussed.Comment: 8 pages, 6 figure

On the definition of matter collineations

It is shown that when the stress-energy tensor of a spacetime is diagonal and is written in the mixed form, its collineations admit infinite dimensional Lie algebras except possibly in the case when the tensor depends on all the spacetime coordinates. The result can be extended for more general second rank tensors

Simulink based Analysis and Realization of Line Commutated Grid Tied Inverter for Renewable Energy Applications

Non-conventional energy resources are increasingly used to fulfill load demands. Before using such energy sources the very important thing is analysis at the basic level. This paper presents analysis and realization of line commutated grid tied inverter for renewable energy applications. The current-voltage and power-voltage characteristics of solar PV array changes as parameters like solar insolation and temperature changes. These characteristics are found and realized using MATLAB software. Line commutated inverters are discussed in this paper for grid interactive modes of operations

Systematic Review of Molecular Biomarkers Predictive of Resistance to CDK4/6 Inhibition in Metastatic Breast Cancer

Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors have revolutionized the treatment of hormone-positive metastatic breast cancers (mBCs). They are currently established as standard therapies in combination with endocrine therapy as first- and second-line systemic treatment options for both endocrine-sensitive and endocrine-resistant mBC populations. In the first-line metastatic setting, the median progression-free survival for the three currently approved CDK4/6 inhibitors, palbociclib, ribociclib, and abemaciclib, with aromatase inhibitors is greater than 2 years (palbociclib 27.6 months; ribociclib 25.3 months; and abemaciclib 28.18 months). Although CDK4/6 inhibitors have significant clinical benefits and enable physicians to delay starting chemotherapy, they are expensive and can be associated with drug toxicities. Here, we have performed a systemic review of the reported molecular markers predictive of drug response including intrinsic and acquired resistance for CDK4/6 inhibition in mBC. The rapidly emerging molecular landscape is captured through next-generation sequencing of breast cancers (DNA with or without RNA), liquid biopsies (circulating tumor DNA), and protein analyses. Individual molecular candidates with robust and reliable evidence are discussed in more depth

Lithium Dendrite Growth Control Using Local Temperature Variation

We have quantified lithium dendrite growth in an optically accessible symmetric Li-metal cell, charged under imposed temperatures on the electrode surface. We have found that the dendrite length measure is reduced up to 43% upon increasing anodic temperature of about 50°C. We have deduced that imposing higher temperature on the electrode surface will augment the reduction rate relative to dendritic peaks and therefore lithium holes can draw near with the sharp deposited tips. We have addressed this mechanism via fundamentals of electrochemical transport
