Quitter sa région pour entrer à l'université : quels sont les facteurs explicatifs de la mobilité géographique des bacheliers ?
2007
New entrants to university : the determinants of regional mobility. This paper aims at understanding the regional mobility of new entrants to university. The regional mobility appears to be marginal. But, the impact of social and academic characteristics shows that self selection processes exist. The combined effects of field and regional impacts highlight the role of the availability of university curricula on student choice.
Analysis of Specific Protein-DNA Interactions
1998
The central issue in the regulation of genome functions is the mechanism of sequence-specific protein-nucleic acid interactions. Gene expression, replication, recombination and DNA condensation in chromatin are steered by binding of regulatory protein ligands to specific sites in DNA. Numerous methods have been developed to study protein-DNA interactions. In this chapter we discuss two widely used and straightforward approaches to address this problem.
Individual and Contextual Determinants of Cruise Passengers’ Behavior at Their Destination: A Survival Approach
2020
The proposed study will present an analysis of cruise passengers’ behavior at their destination. Mobility behavior will be analyzed in relation to socio-demographic characteristics through a survival modeling approach. Data collected through GPS devices on cruise passengers’ behavior in the ports of Palermo and Dubrovnik will be analyzed in order to determine similarities and differences among cruise passengers’ behaviors at their destination, according to socio-demographic characteristics. The authors of this chapter contend that the results of this research, involving the processing and the analysis of GPS data, will be of interest from methodological and destination management perspectiv…
A Functional Role of IκB-ε in Endothelial Cell Activation
2000
Abstract The NF-κB inhibitor IκB-ε is a new member of the IκB protein family, but its functional role in regulating NF-κB-mediated induction of adhesion molecule expression is unknown. In vascular endothelial cells, IκB-ε associates predominantly with the NF-κB subunit Rel A and to a lesser extent with c-Rel, whereas IκB-α and IκB-β associate with Rel A only. Following stimulation with TNF-α, pyrrolidine dithiocarbamate (PDTC), N-acetylcysteine, and dexamethasone prevented IκB kinase-induced IκB-α, but not IκB-β or IκB-ε phosphorylation and degradation. Since the activation of NF-κB is required for the induction of adhesion molecule expression, we examined the role of IκB-ε in the transacti…
Trace analysis by ion mobility spectrometry: From conventional to smart sample preconcentration methods. A review.
2018
Ion mobility spectrometry (IMS) is a rapid and high sensitive technique widely used in security and forensic areas. However, a lack of selectivity is usually observed in the analysis of complex samples due to the scarce resolution of the technique. The literature concerning the use of conventional and novel smart materials in the pretreatment and preconcentration of samples previous to IMS determinations has been critically reviewed. The most relevant strategies to enhance selectivity and sensitivity of IMS determinations have been widely discussed, based in the use of smart materials, as immunosorbents, aptamers, molecularly imprinted polymers (MIPs), ionic liquids (ILs) and nanomaterial. …
536. Internal and international mobility of Romanian immigrants during the crisis
2016
Para paliar los efectos de la crisis económico-laboral, iniciada en 2007, los inmigrantes han desplegado diversas estrategias, entre las que destaca la movilidad geográfica. El artículo indaga en las migraciones que en los últimos años realizan los rumanos en España y desde España, para lo que se utilizan dos fuentes de información complementarias: la estadística y los testimonios de los inmigrantes. Los resultados de la investigación muestran el notable aumento de la circulación interior de trabajadores durante los primeros años y el progresivo aumento de las salidas, ya sea para retornar al lugar de origen, emigrar a otros países o desplazarse entre diferentes lugares. En general, estos d…
Human powered mobility per una città più green, equa e sicura.
2014
“Quando una società segna un prezzo sul tempo, tra l’equità e la velocità veicolare si stabilisce una correlazione inversa” Ivan Illich Partendo dall’elogio della bicicletta di Illich (1973) e Augè (2009), il contributo riguarda gli effetti sulla qualità della vita della soft mobility, in termini di riduzione di traffico, inquinamento, tempo impiegato per spostarsi, di riduzione dei consumi energetici, di ‘sostenibilità’ in senso lato, di recupero dello spazio della polis e di equità sociale. Analizzando le indicazioni in merito alla mobilità date dall’Unione Europea affinché si incida su abitudini e stili di vita e sulla conformazione stessa della città, consapevoli che il trasporto pubbli…
Inter-industry job mobility in the knowledge economy in Finland
2013
Purpose – The purpose of this paper is to investigate inter-industry labor mobility, paying special attention to workers who move into high-tech (HT) sectors or knowledge-intensive business services (KIBSs). This study inquires whether skilled workers are mobile and whether the characteristics of mobile workers support the effective transfer of knowledge across industries. Design/methodology/approach – Census data representing 7 percent of Finnish residents were used. The micro-econometric estimation method with correction of sample selection bias was applied. Findings – The results show that young workers are the most mobile, whereas mobility decreased for those with previous work experie…
Exploration of future changes of residential locations in an urban agglomeration using an individual-based simulation model (Mobisim)
2015
To ensure that housing supply is suitable to households’ needs and preferences represents a major planning concern. These needs and preferences depend on the households’ characteristics and on their lifecycle changes (union, birth, divorce…). Residential choice factors are numerous (housing and residential environment characteristics) and their role is often different according to the types of households. Residential dynamics involve a great variety of elements, in interaction with each other, and the causal relationships are difficult to identify. Thus, it is not possible to predict the households’ residential behaviour, nor their possible evolutions, without a suitable tool. To study intr…
Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study
2020
The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …
