Social security, income taxation and poverty alleviation [PDF]

open access: yes
In this paper I consider the normative arguments that justify a public social security system as a redistributive device when goverment is concerned with individual utility and poverty. Redistribution can be done using social security, income taxation or

Unlocking Photodetection Mode Switching from a Simple Lateral Design

open access: yesAdvanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

Social Security and Risk Sharing [PDF]

open access: yes
In this paper we identify conditions under which the introduction of a pay-as-you-go social security system is ex ante Pareto-improving in a stochastic overlapping generations economy with capital accumulation and land. We argue that these conditions are

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

open access: yesAdvanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Security Psychology as Social Systemic Phenomenon

open access: yesPsychology in Russia: State of Art, 2011
Security psychology is considered through social systemic search for reciprocal contiguity and mutual completion of existing advances of psychology and conceptual security understanding. The ability of systemic vision of security and its cognitive and practical specifics are demonstrated.

The Role of Immigration in Sustaining the Social Security System: A Political Economy Approach [PDF]

open access: yes
In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. We characterize sub-game perfect Markov equilibria where immigration policy

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

"Social Security Annuities and Transfers: Distributional and Tax Implications" [PDF]

open access: yes
The division of social security (OASI) benefits into an annuity portion and a transfer portion has been well documented. I have discussed this issue extensively in previous work (1987b, 1988, 1990, and forthcoming), as did Burkhauser and Warlick (1981 ...

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

open access: yesAdvanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...
