Do we value mobility?

2015

Is there a trade-off between people's preference for income equality and income mobility? Testing for the existence of such a trade-off is difficult because mobility is a multifaceted concept. We analyse results from a questionnaire experiment based on simple precise concepts of income inequality and income mobility. We fnd no direct trade-off in preference between mobility and equality, but an indirect trade-off, applying when more income mobility can only be obtained at the expense of some income inequality. Mobility preference - but not equality preference - appears to be driven by personal experience of mobility.

Effects of a 12‐month home‐based exercise program on functioning after hip fracture – Secondary analyses of an RCT

2022

Background Long-term functional limitations are common after hip fractures. Exercise may alleviate these negative consequences but there is no consensus on an optimal training program. The objective was to study the effects of a 12-month home-based supervised, progressive exercise program on functioning, physical performance, and physical activity. Methods Secondary analysis of a randomized controlled trial targeting patients with surgical repair of a hip fracture, aged >= 60 years, Mini-Mental State Examination (MMSE) score of >= 12. The participants were randomized into Exercise (n = 61) or Usual care (n = 60). Assessments at baseline, 3, 6, and 12 months included Lawton's Instrumental Ac…

Stepping up to strike: a union mobilization case study of Polish migrant workers in the Netherlands

2015

This article examines a union mobilization of Polish temporary agency workers in the Netherlands. The case study contributes to the migrant organizing literature a micro-level account of the dynamics of mobilization from the viewpoint of the migrants and organizers involved. The findings emphasize the importance of key actors in building solidarities within and between different groups of workers in fragmented workplaces, with implications for unions seeking new ways to respond to changing employment practices. This study highlights some of the possibilities and limitations of organizing among contractually fragmented workforces.

Investigation of acceptor levels and hole scattering mechanisms in p-gallium selenide by means of transport measurements under pressure

1997

The effect of pressure on acceptor levels and hole scattering mechanisms in p-GaSe is investigated through Hall effect and resistivity measurements under quasi-hydrostatic conditions up to 4 GPa. The pressure dependence of the hole concentration is interpreted through a carrier statistics equation with a single (nitrogen) or double (tin) acceptor whose ionization energies decrease under pressure due to the dielectric constant increase. The pressure effect on the hole mobility is also accounted for by considering the pressure dependencies of both the phonon frequencies and the hole-phonon coupling constants involved in the scattering rates.

How endogenous asymmetries in interregional market access trigger regional divergence

2005

International audience; We investigate how asymmetric trade patterns in differentiated products affect the regional distribution of economic activities. The asymmetry in interregional market access is an endogenous result of price competition and industry location and arises for intermediate values of trade costs. We show that the emergence of one-way trade in differentiated products gives rise to strong agglomeration forces and leads to the absorption of the smaller region's industry by the larger region. The number of spatial equilibria increases once the pattern of trade is endogenously accounted for.

Memorias silenciadas en la construcción de los servicios sociales

2006

Joaquin.Garcia-Roca@uv.es Este artículo revisa la historia de la formación del sistema público de servicios sociales en España y expone «las rutas que no se navegaron», los derechos y las aspiraciones a que dieron lugar o conformaron unas expectativas, el origen de la des institucionalización, la pérdida de movimiento social y el desarrollo comunitario. El principio neoliberal y la exaltación de la gestión, la conquista de las profesiones y la ingeniería social han contribuido a silenciar un proceso que todavía se puede recuperar. ¿Cómo? El autor plantea que los servicios sociales han de ser capaces de producir significados personales tales como el sentido de pertenencia, la confianza, la i…

40 years of time geography: from the conceptual framework to the GI Science contributions

2011

International audience; Social scientists studying the effects of space on human behavior usually consider the time dimension as an external factor. Activities are analyzed in an aggregate sense such that the process of individual decision-making is depicted as the single case of "the average individual." In order to link efficiently space and time dimensions, Torsten Hägerstrand defined in 1970's the concept of Time Geography and thereby founded the school of Swedish geography. His conceptual framework was destined to change the course of history in the social sciences. After 40 years, this success has transcended scientific boundaries. In this paper, we propose to review the evolution of …

Fructan Biosynthesis by Intra- and Extracellular Zymomonas mobilis Levansucrase after Simultaneous Production of Ethanol and Levan

2003

Summary The chemical composition of the Zymomonas mobilis biomass and the culture liquid after ethanol and levan synthesis were studied. The activities of intra- and extracellular levansucrase produced by the Z. mobilis strain 113 ”S” under optimum conditions both for levan and fructooligosaccharide (FOS) synthesis were also determined. It was shown that levan production relates to the reduction of the carbohydrate and lipid content in the biomass by increasing the nucleic acid and protein content. The levan producing activity of cellular levansucrase after ethanol and levan synthesis was approximately 30–40% of the total activity in the second fermentation stage. It was established that th…

Expectations Towards International Study Visits – Preliminary Research Findings

2021

Abstract Objective: The objective of this paper is to present the preliminary research findings concerning the expectations towards international study visits undertaken by university students hailing from different higher education institutions around Europe on the canvas of internationalization as a concept. Methodology: The research was carried out on a group of 440 students from 5 European countries. The study covered the population of students of faculties whose graduates are preparing to work in business. The basic research tool was a questionnaire with dominating closed questions and the possibility for respondents to indicate more than one answer. The answers of the respondents were…
