Skilled emigration and exchange rate : theory and empirics

In this paper we build a theoretical model on the wage effect of skilled emigration to the fluctuations in real exchange rate through the relative prices of nontradables. Our theoretical model predicts that skilled emigration is associated with an increase in the prices of nontradable, which in turn appreciates the exchange rate. We provide robust empirical support to a higher skilled emigration associated with higher prices in nontradables and appreciation of the real effective exchange rate. Based on two samples of countries with 51 and 67 observations, in 1990 and 2000 respectively, we find robust empirical support to a higher skilled emigration associated with higher prices in nontradables and appreciation of the REER. In addition, the support for the remittance-channel of the Dutch disease is also significant; overall, our findings corroborate the remittance-based Dutch disease phenomenon by providing an additional channel through which the labor mobility across borders affects the real exchange rate volatility.

The secret to legal foretelling: generic and inter-generic aspects of vagueness in contracts, patents and regulations

In this genre analysis research paper, we compare U.S. patents, contracts, and regulations on technical matters with a focus upon the relation between vagueness and communicative purposes and subpurposes of these three genres. Our main interest is the investigation of intergeneric conventions across the three genres, based on the software analysis of three corpora (one for each genre, 1 million words per corpus). The result of the investigation is that intergeneric conventions are found at the level of types of expressed linguistic vagueness, but that intergeneric conventions at the level of actual formulations are rare. The conclusion is that at this latter level the influence from the situation type underlying the individual genre is more important than the overarching legal character of the genres, when we talk about introducing explicit vagueness in the text.

Cycling habits and other psychological variables affecting commuting by bicycle in Madrid, Spain

To develop effective cycling policies, decision makers and administrators should know the factors influencing the use of the bicycle for daily mobility. Traditional discrete choice models tend to be based on variables such as time and cost, which do not sufficiently explain the choice of the bicycle as a mode of transportation. Because psychological factors have been identified as particularly influential in the decision to commute by bicycle, this paper examines the perceptions of cycling factors and their influence on commuting by bicycle. Perceptions are measured by attitudes, other psychological variables, and habits. Statistical differences in the variables are established in relation to the choice of commuting mode and bicycle experience (commuter, sport-leisure, no use). Doing so enables the authors to identify the main barriers to commuting by bicycle and to make recommendations for cycling policies. Two underlying structures (factors) of the attitudinal variables are identified: direct benefits and long-term benefits. Three other factors are related to variables of difficulty: physical conditions, external facilities, and individual capacities. The effect of attitudes and other psychological variables on people's decision to cycle to work-place of study is tested by using a logit model. In the case study of Madrid, Spain, the decision to cycle to work-place of study is heavily influenced by cycling habits (for noncommuting trips). Because bicycle commuting is not common, attitudes and other psychological variables play a less important role in the use of bikes.

Molecular and cell biology aspects of plague

A 70-kb virulence plasmid (sometimes called pYV) enables Yersinia spp. to survive and multiply in the lymphoid tissues of their host. It encodes the Yop virulon, a system consisting of secreted proteins called Yops and their dedicated type III secretion apparatus called Ysc. The Ysc apparatus forms a channel composed of 29 proteins. Of these, 10 have counterparts in almost every type III system. Secretion of some Yops requires the assistance, in the bacterial cytosol, of small individual chaperones called the Syc proteins. These chaperones act as bodyguards or secretion pilots for their partner Yop. Yop proteins fall into two categories. Some are intracellular effectors, whereas the others are “translocators” needed to deliver the effectors across the eukaryotic plasma membrane, into eukaryotic cells. The translocators (YopB, YopD, LcrV) form a pore of 16–23 Å in the eukaryotic cell plasma membrane. The effector Yops are YopE, YopH, YpkA/YopO, YopP/YopJ, YopM, and YopT. YopH is a powerful phosphotyrosine phosphatase playing an antiphagocytic role by dephosphorylating several focal adhesion proteins. YopE and YopT contribute to antiphagocytic effects by inactivating GTPases controlling cytoskeleton dynamics. YopP/YopJ plays an anti-inflammatory role by preventing the activation of the transcription factor NF-κB. It also induces rapid apoptosis of macrophages. Less is known about the role of the phosphoserine kinase YopO/YpkA and YopM.

Social and immigration factors in intimate partner violence among Ecuadorians, Moroccans and Romanians living in Spain

Background: Intimate partner violence (IPV) against women occurs in all countries, all cultures and at every level of society; however, some populations may be at greater risk than others. The aim of this study was to explore IPV prevalence among Ecuadorian, Moroccan and Romanian immigrant women living in Spain and its possible association with their personal, family, social support and immigration status characteristics. Methods: Cross-sectional study of 1607 adult immigrant women residing in Barcelona, Madrid and Valencia (2011). Prevalence rates and adjusted odds ratios (AORs) were calculated, with current IPV being the outcome. Different women’s personal (demographic), family, social support and immigration status characteristics were considered as explicative and control variables. All analyses were separated by women’s country of origin. Results: Current IPV prevalence was 15.57% in Ecuadorians, 10.91% in Moroccans and 8.58% in Romanians. Some common IPV factors were found, such as being separated and/or divorced. In Romanians, IPV was also associated with lack of social support [AOR 5.96 (1.39–25.62)] and low religious involvement [AOR 2.17 (1.06–4.43)]. The likelihood of current IPV was lower among women without children or other dependants in this subgroup [AOR 0.29 (0.093–0.92)]. Conclusion: The IPV prevalence rates obtained for Moroccan, Romanian and Ecuadorian women residing in Spain were similar. Whereas the likelihood of IPV appeared to be relatively evenly distributed among Moroccan and Ecuadorian women, it was higher among Romanian women in socially vulnerable situations related to family responsibilities and the lack of support networks. The importance of intervention in the process of separation and divorce was common to all women.

Plastisol gelation and fusion rheological aspects

This study deals with the rheological aspects of poly-vinyl chloride (PVC) plastisol gelation and fusion processes in foamable formulations. Here, such processes are simulated by temperature-programmed experiment (5 K min−1) in which complex viscosity components are continuously recorded. Nineteen samples based on a PVC-VAC (vinyl acetate 95/5) copolymer with 100 phr plasticizer have been studied, differing only by the plasticizer structure. The sample shear modulus increases continuously with temperature until a maximum, long time after the end of the dissolution process as characterized by DSC. The temperature at the maximum varies between 345 and 428 K with a clear tendency to increase almost linearly with the plasticizer molar mass, and to vary with the flexibility and the degree of branching of the plasticizer molecule. The shear modulus increase is interpreted in terms of progressive “welding” of swelled particles by polymer chain reptation. The plasticizer nature would mainly affect the friction parameter of chain diffusion.

Trends and Disparities in Mortality Among Spanish-Born and Foreign-Born Populations Residing in Spain, 1999–2008

Spain’s immigrant population has increased 380 % in the last decade, accounting for 13.1 % of the total population. This fact has led her to become during 2009 the eighth recipient country of international immigrants in the world. The aim of this article is to describe the evolution of mortality and the main causes of death among the Spanish-born and foreign-born populations residing in Spain between 1999 and 2008. Age-standardised mortality rates (ASRs), average age and comparative mortality ratios among foreign-born and Spanish-born populations residing in Spain were computed for every year and sub-period by sex, cause of death and place of birth as well as by the ASR percentage change. During 1999–2008 the ASR showed a progressive decrease in the risk of death in the Spanish-born population (−17.8 % for men and −16.6 % for women) as well as in the foreign-born one (−45.9 % for men and −35.7 % for women). ASR also showed a progressive decrease for practically all the causes of death, in both populations. It has been observed that the risk of death due to neoplasms and respiratory diseases among immigrants is lower than that of their Spanish-born counterparts, but risk due to external causes is higher. Places of birth with the greater decreases are Northern Europe, Eastern Europe, Western Europe, Southern Europe, and Latin America and the Caribbean. The research shows the differences in the reduction of death risk between Spanish-born and immigrant inhabitants between 1999 and 2008. These results could contribute to the ability of central and local governments to create effective health policy. Further research is necessary to examine changes in mortality trends among immigrant populations as a consequence of the economic crisis and the reforms in the Spanish health system. Spanish data sources should incorporate into their records information that enables them to find out the immigrant duration of permanence and the possible impact of this on mortality indicators.

Restrictions on Aliens in the United Kingdom, 1914-1919 : a Study of the Origins and Political Background of the Aliens Restrictions Acts of 1914 and 1919.

At first glance the Aliens Restriction Act of 1914, which was introduced and passed on the first day of World War One, seems a hasty and ill-prepared piece of legislation. Actually, when examined in the light of Arthur Marwick's thesis that war is a forcing house for pre-existent social and governmental ideas, it becomes clear that the act was not after all the product of hastily formed notions. In point of fact it followed the precedent of detailed draft clauses produced in 1911 by a sub-committee of the Committee of Imperial Defence established to consider the treatment of aliens in the event of war. Indeed the draft clauses and the restrictions embodied in the 1914 act were strikingly similar to restrictions on aliens legislated in 1793. Hostility to aliens had been growing from 1905 to 1914 and this hostility blossomed into xeno-phobia on the outbreak of war, a crucial precondition for the specifically anti-enemy fears of the time. In 1919 the Aliens Restriction (Amendment) Bill was introduced into parliament to extend temporarily the provisions of the 1914 act thus permitting the Home Secretary to plan permanent, detailed legislation. Two minority groups of MPs with extreme views on the treatment of aliens were prominent in the debates on this bill. The extreme Liberal group which advocated leniency in the treatment of aliens had little effect on the final form of the bill, but the extreme Conservative group, which demanded severe restrictions on aliens, succeeded in persuading the government to include detailed restrictions. Despite its allegedly temporary nature, the Aliens Restriction (Amendment) Act of 1919 was renewed annually until 1971.
