Official Regulations and the Shadow Economy: A Labour Market Approach [PDF]

open access: yes, 2002
This work revisits the role of regulations in emergence o f the shadow economy. In particular, it supplements the previous theoretical research that mainly ignored the fact that the decision to “go underground” is essentially a result of both employers ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Funding the Transition from Pay-As-You-Go Pensions by Taking Capital Gains on Land. [PDF]

open access: yes
The transition from unfunded pensions may impose a "double burden" on a transitional generation, which must both pay taxes to finance current pension liabilities and save for their own retirement. There are also economic gains which will accrue to future

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

R&D and Patents: An Attempt of Application of the Griliches’s Model in a Transitional Economy

open access: yesAsian Journal of Technology Management, 2013
The main aim of this paper is to analyze relations between patent activity and R&D activity in Poland being a transitional economy in Central and Eastern Europe. The macro-perspective will be considered here. The paper begins with data on patents and

The energy transition of the transition economies: An empirical analysis [PDF]

open access: yesEnergy Economics, 2013
The aggregate manufacturing energy intensity of 28 countries in Eastern Europe and Central Asia had declined by 35 percent during 1998-2008. This study reveals strong evidence of convergence: less efficient countries improved more rapidly and the cross-country variance in energy productivity narrowed over time. An index decomposition analysis indicates

Formal Education and Public Knowledge [PDF]

open access: yes
In this paper, I examine the transitional dynamics of an economy populated by individuals who split their time between acquiring a formal education, producing final goods, and innovating.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

The Determinants of Actual Migration and the Role of Wages and Unemployment in Albania: an Empirical Analysis [PDF]

open access: yesThe European Journal of Comparative Economics, 2008
The paper explores the determinants of internal migration in Albania, adopting the Harris-Todaro approach to migration: an internal migration function is estimated using district wage and unemployment rate differentials.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...
