    Cyclic nucleotide-gated channels (CNGCs) are nonselective cation channels found in plants, animals, and some bacteria. They have a six-transmembrane/one- pore structure, a cytosolic cyclic nucleotide-binding domain, and a cytosolic calmodulin-binding domain. Despite their functional similarities, the plant CNGC family members appear to have different conserved amino acid motifs within corresponding functional domains than animal and bacterial CNGCs do. Here we describe the development and application of methods employing plant CNGC-specific sequence motifs as diagnostic tools to identify novel candidate channels in different plants. These methods are used to evaluate the validity of annotations of putative orthologs of CNGCs from plant genomes. The methods detail how to employ regular expressions of conserved amino acids in functional domains of annotated CNGCs and together with Web tools such as PHI-BLAST and ScanProsite to identify novel candidate CNGCs in species including Physcomitrella patens. © Springer Science+Business Media New York 2013.

    Clausen, Jens; Heinesen, Eskil; Hummelgaard, Hans

    We analyse the effect of active labour-market programmes on the hazard rate into regular employment for newly arrived immigrants using the timing-of-events duration model. We take account of language course participation and progression in destination country language skills. We use rich...... administrative data from Denmark. We find substantial lock-in effects of participation in active labour-market programmes. Post programme effects on the hazard rate to regular employment are significantly positive for wage subsidy programmes, but not for other types of programmes. For language course...... participants, improvement in language proficiency has significant and substantial positive effects on the hazard rate to employment....

    Full Text Available Bandwidth plays an important role for quality of service in most network systems. There are many technologies developed to increase host bandwidth in a LAN environment. Most of them need special hardware support, such as switching hub that supports IEEE Link Aggregation standard. In this paper, we propose a Linux solution to increase the bandwidth between hosts with multiple network adapters connected to a regular switching hub. The approach is implemented as two Linux kernel modules in a LAN environment without modification to the hardware and operating systems on host machines. Packets are dispatched to bonding network adapters for transmission. The proposed approach is backward compatible, flexible and transparent to users and only one IP address is needed for multiple bonding network adapters. Evaluation experiments in TCP and UDP transmission are shown with bandwidth gain proportionally to the number of network adapters. It is suitable for large-scale LAN systems with high bandwidth requirement, such as clustering systems.

  5. Economic effects of immigrants on native and foreign-born workers: complementarity, substitutability, and other channels of influence.

    The authors use Standard Metropolitan Statistical Area (SMSA) data constructed from 1980 census microdata files and other sources to estimate a structural model of native/foreign-born labor demand and labor supply which distinguishes the effects upon real wages of each type of labor and on the employment of natives. The authors specify, econometrically estimate, and simulate the structural model which incorporates not only a production structure channel through which immigrants influence area real wages and employment, but also demand and native labor supply channels. It is noted that while these are not the only channels through which immigrants may affect native workers, the model nonetheless constitutes a step in the direction of a general equilibrium approach. In the production structure channel, immigrants and natives are found to be substitutes in production. Immigration lowers foreign-born wage rates and leads to lower wages for natives. The negative effects of the production channel usually are ameliorated through the demand channel. Further, immigrants add to local demand through their earnings and potentially through non-labor income, while also lowering unit costs and local prices which enhances real incomes and potentially net exports, and thus the demands for local output and area labor. The author discusses findings of interest from the simulation results based upon an analysis of all areas.

  6. Ion channel density regulates switches between regular and fast spiking in soma but not in axons.

    Full Text Available The threshold firing frequency of a neuron is a characterizing feature of its dynamical behaviour, in turn determining its role in the oscillatory activity of the brain. Two main types of dynamics have been identified in brain neurons. Type 1 dynamics (regular spiking shows a continuous relationship between frequency and stimulation current (f-I(stim and, thus, an arbitrarily low frequency at threshold current; Type 2 (fast spiking shows a discontinuous f-I(stim relationship and a minimum threshold frequency. In a previous study of a hippocampal neuron model, we demonstrated that its dynamics could be of both Type 1 and Type 2, depending on ion channel density. In the present study we analyse the effect of varying channel density on threshold firing frequency on two well-studied axon membranes, namely the frog myelinated axon and the squid giant axon. Moreover, we analyse the hippocampal neuron model in more detail. The models are all based on voltage-clamp studies, thus comprising experimentally measurable parameters. The choice of analysing effects of channel density modifications is due to their physiological and pharmacological relevance. We show, using bifurcation analysis, that both axon models display exclusively Type 2 dynamics, independently of ion channel density. Nevertheless, both models have a region in the channel-density plane characterized by an N-shaped steady-state current-voltage relationship (a prerequisite for Type 1 dynamics and associated with this type of dynamics in the hippocampal model. In summary, our results suggest that the hippocampal soma and the two axon membranes represent two distinct kinds of membranes; membranes with a channel-density dependent switching between Type 1 and 2 dynamics, and membranes with a channel-density independent dynamics. The difference between the two membrane types suggests functional differences, compatible with a more flexible role of the soma membrane than that of the axon membrane.

  7. Modulation of rod photoreceptor output by HCN1 channels is essential for regular mesopic cone vision.

    Retinal photoreceptors permit visual perception over a wide range of lighting conditions. Rods work best in dim, and cones in bright environments, with considerable functional overlap at intermediate (mesopic) light levels. At many sites in the outer and inner retina where rod and cone signals interact, gap junctions, particularly those containing Connexin36, have been identified. However, little is known about the dynamic processes associated with the convergence of rod and cone system signals into ON- and OFF-pathways. Here we show that proper cone vision under mesopic conditions requires rapid adaptational feedback modulation of rod output via hyperpolarization-activated and cyclic nucleotide-gated channels 1. When these channels are absent, sustained rod responses following bright light exposure saturate the retinal network, resulting in a loss of downstream cone signalling. By specific genetic and pharmacological ablation of key signal processing components, regular cone signalling can be restored, thereby identifying the sites involved in functional rod-cone interactions.

  8. Ventricular action potential adaptation to regular exercise: role of β-adrenergic and KATP channel function.

    2017-08-01

    Regular exercise training is known to affect the action potential duration (APD) and improve heart function, but involvement of β-adrenergic receptor (β-AR) subtypes and/or the ATP-sensitive K + (K ATP ) channel is unknown. To address this, female and male Sprague-Dawley rats were randomly assigned to voluntary wheel-running or control groups; they were anesthetized after 6-8 wk of training, and myocytes were isolated. Exercise training significantly increased APD of apex and base myocytes at 1 Hz and decreased APD at 10 Hz. Ca 2+ transient durations reflected the changes in APD, while Ca 2+ transient amplitudes were unaffected by wheel running. The nonselective β-AR agonist isoproterenol shortened the myocyte APD, an effect reduced by wheel running. The isoproterenol-induced shortening of APD was largely reversed by the selective β 1 -AR blocker atenolol, but not the β 2 -AR blocker ICI 118,551, providing evidence that wheel running reduced the sensitivity of the β 1 -AR. At 10 Hz, the K ATP channel inhibitor glibenclamide prolonged the myocyte APD more in exercise-trained than control rats, implicating a role for this channel in the exercise-induced APD shortening at 10 Hz. A novel finding of this work was the dual importance of altered β 1 -AR responsiveness and K ATP channel function in the training-induced regulation of APD. Of physiological importance to the beating heart, the reduced response to adrenergic agonists would enhance cardiac contractility at resting rates, where sympathetic drive is low, by prolonging APD and Ca 2+ influx; during exercise, an increase in K ATP channel activity would shorten APD and, thus, protect the heart against Ca 2+ overload or inadequate filling. NEW & NOTEWORTHY Our data demonstrated that regular exercise prolonged the action potential and Ca 2+ transient durations in myocytes isolated from apex and base regions at 1-Hz and shortened both at 10-Hz stimulation. Novel findings were that wheel running shifted the

    To explore reasons for attending a general emergency outpatient clinic versus a regular general practitioner (RGP). Cross-sectional study using a multilingual anonymous questionnaire. Native and immigrant walk-in patients attending a general emergency outpatient clinic in Oslo (Monday-Friday, 08:00-23:00) during 2 weeks in September 2009. We included 1022 walk-in patients: 565 native Norwegians (55%) and 457 immigrants (45%). Patients' reasons for attending an emergency outpatient clinic versus their RGP. Among patients reporting an RGP affiliation, 49% tried to contact their RGP before this emergency encounter: 44% of native Norwegian and 58% of immigrant respondents. Immigrants from Africa [odds ratio (OR) = 2.55 (95% confidence interval [CI]: 1.46-4.46)] and Asia [OR = 2.32 (95% CI: 1.42-3.78)] were more likely to contact their RGP before attending the general emergency outpatient clinic compared with native Norwegians. The most frequent reason for attending the emergency clinic was difficulty making an immediate appointment with their RGP. A frequent reason for not contacting an RGP was lack of access: 21% of the native Norwegians versus 4% of the immigrants claimed their RGP was in another district/municipality, and 31% of the immigrants reported a lack of affiliation with the RGP scheme. Access to primary care provided by an RGP affects patients' use of emergency health care services. To facilitate continuity of health care, policymakers should emphasize initiatives to improve access to primary health care services. KEY POINTS Access to immediate primary health care provided by a regular general practitioner (RGP) can reduce patients' use of emergency health care services. The main reason for attending a general emergency outpatient clinic was difficulty obtaining an immediate appointment with an RGP.

    Typical performance of low-density parity-check (LDPC) codes over a general binary-input output-symmetric memoryless channel is investigated using methods of statistical mechanics. Relationship between the free energy in statistical-mechanics approach and the mutual information used in the information-theory literature is established within a general framework; Gallager and MacKay-Neal codes are studied as specific examples of LDPC codes. It is shown that basic properties of these codes known for particular channels, including their potential to saturate Shannon's bound, hold for general symmetric channels. The binary-input additive-white-Gaussian-noise channel and the binary-input Laplace channel are considered as specific channel models

  15. Attitudinal impact and cognitive channelling of immigration stereotypes through the news

    2013-10-01

    Full Text Available Introduction: Based on research on the framing effect and research on the treatment of immigration, the processes of reception and impact of news about crime are analyzed. Method: We conducted two experimental investigations in which participants were exposed to a news story and later filled in a questionnaire with self-report scales. Two independent variables were manipulated: the mention of protagonists’ national/ geographic origin in the news story and the involvement with the topic. Results: The study indicates that when the involvement with the news story is low, the presence of information about the nationality of the protagonist exerted an indirect effect through attitudinal impact. However, when involvement is high, the indirect effect is explained by the activation of trains of thought which influence the formation and/or reinforcement of negative beliefs about immigration. Conclusions: The results are consistent with a dual model of news framing effects and reinforce the recommendations made by some organisations about not reporting the nationality of the protagonists of a criminal act in news programmes.

    2016-04-01

    This paper presents the theoretical models describing the growth of filamentary channels of nanostructured non-metallic coatings formed by anodizing and microplasma oxidation. The authors identified dependences of the number of pores on the coating thickness. The paper presents graphic dependences of the number of filamentary channels on the process time and the coating thickness. These dependences allow calculating through and surface porosity, and in cases, when the pores are filled with functional material, they allow calculating the concentration distribution of this functional material throughout the coating thickness. The theoretical models enhance our understanding of the nature of anode processes and can be used to describe and forecast the growth and filling of porous coatings, so they can also be used to create functional and bioactive materials.

    Abstract Aims: The mechanisms underlying numerous biological roles of hydrogen sulfide (H2S) remain largely unknown. We have previously reported an inhibitory role of H2S in the L-type calcium channels in cardiomyocytes. This prompts us to examine the mechanisms underlying the potential regulation of H2S on the ion channels. Results: H2S showed a novel inhibitory effect on Ito potassium channels, and this effect was blocked by mutation at the Cys320 and/or Cys529 residues of the Kv4.2 subunit. H2S broke the disulfide bridge between a pair of oxidized cysteine residues; however, it did not modify single cysteine residues. H2S extended action potential duration in epicardial myocytes and regularized fatal arrhythmia in a rat model of myocardial infarction. H2S treatment significantly increased survival by ∼1.4-fold in the critical 2-h time window after myocardial infarction with a protection against ventricular premature beats and fatal arrhythmia. However, H2S did not change the function of other ion channels, including IK1 and INa. Innovation and Conclusion: H2S targets the Cys320/Cys529 motif in Kv4.2 to regulate the Ito potassium channels. H2S also shows a potent regularizing effect against fatal arrhythmia in a rat model of myocardial infarction. The study provides the first piece of evidence for the role of H2S in regulating Ito potassium channels and also the specific motif in an ion channel labile for H2S regulation. Antioxid.

    Theoretical models are developed for growth and filling processes in filamentary channels of nanostructured non-metallic coatings produced by anodizing and microplasma oxidation. Graphical concentration distributions are obtained for channel-reacting anions, cations, and sparingly soluble reaction products depending on the time of electric current transmission and the length of the filamentary channel. Graphical distributions of the front moving velocity for the sparingly soluble compound are presented. The resulting model representation increases the understanding of the anodic process nature and can be used for a description and prediction of porous anodic film growth and filling. It is shown that the character of the filamentary channel growth and filling causes a variety of processes determining the textured metal - nonmetallic inorganic coating phase boundary formation.

    Dietary acculturation for immigrant groups has largely been attributed to the “Westernization” of indigenous diets, as characterized by an increased consumption of unhealthy American foods (i.e. fast foods, hamburgers). However, acculturation and adoption of western dietary habits may not fully explain new dietary patterns among racial/ethnic minority immigrants. The immigrant diet may change in such a way that it elaborates on specific ethnic traditions in addition to the incorporation of Western food habits. In this paper, we explore the role that festival foods, those foods that were once eaten a few times a year and on special occasions, play in the regular diet of immigrants to the U.S. This paper will focus on the overconsumption of ethnic festival foods, which are often high in carbohydrates, animal protein, sugar and fat, as opposed to Western “junk” food, as an explanation for the increased risk of cardiometabolic disorders among new immigrant groups.

    A decade ago, the political party of the Italian center-right voted a law restricting immigration. The law became effective in early 2005, when the Italian parliament approved the decree for its application, but one of its articles, granting amnesty for illegal immigrant workers, became immediately effective in July 2002. As a result, 650,000 immigrants were granted the status of foreign nationals in Italy. In this paper, we examine whether the increase in the prevalence of "regular immigrants" has led to an improvement in health outcomes of babies born to migrant women, measured in terms of birth weight. Two hitherto unexploited birth sample surveys published by Italian Institute of Statistics were used for this study. Our estimates show that regularized immigration reduced the probability of low birth weight. Copyright © 2015 Elsevier B.V. All rights reserved.

Parallel development of invariant coordinate-space regularization is obtained by regularized functional integration of the momenta. As representative examples of the general formulation, the regularized general non-linear sigma model and regularized quantum gravity are discussed. copyright 1987 Academic Press, Inc

  15. Immigrants in Slovenia: Integration Aspects

    Directory of Open Access Journals (Sweden)

    Janja Žitnik

    2004-09-01

    Full Text Available On the basis of the latest statistics, the author estimates the present share of first- and second-generation immigrants in Slovenia’s population. After examining the quantity and intensity of those public efforts in Slovenia that have been focused on unresolved problems of the immigrants’ social and cultural integration, she continues to question the equality of immigrant minorities in Slovenia, and the sufficiency of the existing programs aimed at facilitating their integration with Slovenian society at large. She explains her doubts about the general assumption that a very clear distinction should be made between the rights of the autochthonous minorities and those of the immigrant ones as far as their special protection is concerned. In the third section of this article, the author discusses the social-ethnic stratification of Slovenian society and tries to look into the psychological background of the nationality/ethnicity statistics. She presents some aspects of the immigrants’ daily experience in Slovenian social, cultural, educational and working milieu, and points to the authorities’ attitude toward them. She comments on the burning issue of the “deleted residents”, and illustrates it with the experience of one of the persons involved. The fourth section, in which the most regular symptoms of Slovenian xenophobia are presented, consists of first-hand observations and focuses on the daily human attitude of the national majority towards the immigrant minorities. Finally the author compares the nature of the specific needs of Slovenians as a “European national minority” with the needs of the immigrant minorities in Slovenia.

    Immigration is one of the most important policy debates in Western countries. However, one aspect of the debate is often mischaracterized by accusations that higher levels of immigration lead to higher levels of crime. The evidence, based on empirical studies of many countries, indicates that there is no simple link between immigration and crime. Crucially, the evidence points to substantial differences in the impact on property crime, depending on the labor market opportunities of immigrant ...

  18. Immigration and income inequality

    Deding, Mette; Hussain, Azhar; Jakobsen, Vibeke

    2010-01-01

    During the last two decades most Western countries have experienced increased net immigration as well as increased income inequality. This article analyzes the effects on income inequality of an increased number of immigrants in Denmark and Germany for the 20- year period 1984-2003 and how...... the impact of the increased number of immigrants differs between the two countries. We find higher inequality for immigrants than natives in Denmark but vice versa for Germany. Over the period 1984-2003, this particular inequality gap has narrowed in both countries. At the same time, the contribution...... of immigrants to overall inequality has increased, primarily caused by increased between-group inequality. The share of immigrants in the population is more important for the change in overall inequality in Denmark than in Germany, while the opposite is the case for inequality among immigrants....

We show that immigration policy choice affects and is affected by the migratory decisions of skilled and unskilled foreign workers. From this interaction multiple equilibria may arise, which are driven by the natives' expectations on the migrants' size and skill composition (and, hence, on the welfare effects of immigration). In particular, pessimistic (optimistic) beliefs induce a country to impos...

    estimate the number of irregular economic immigrants in Mallorca. We used the capture-recapture method, an indirect method based on contrasts of data from two or more sources. Data were obtained from the Delegación de Gobierno (police and immigration authority), Comisiones Obreras (labor union), and institutions that provide health-related services to immigrants. Individuals were identified by birth date and country of origin. The total number of economic immigrants estimated with this method was 39 392. According to the Delegación de Gobierno data, the number of regular immigrants on the date of our inquiry was 9000. With the capture-recapture method, the number of irregular immigrants in Mallorca was therefore estimated at 30 000. The capture-recapture method can be useful to estimate the population of irregular immigrants in a given area at a given time, if sufficiently precise information on the identity of each individual can be obtained.

    Andersson, Fredrik; García-Pérez, Mónica; Haltiwanger, John; McCue, Kristin; Sanders, Seth

    2014-01-01

    Casual observation suggests that in most U.S. urban labor markets, immigrants have more immigrant coworkers than native-born workers do. While seeming obvious, this excess tendency to work together has not been precisely measured, nor have its sources been quantified. Using matched employer–employee data from the U.S. Census Bureau Longitudinal Employer-Household Dynamics (LEHD) database on a set of metropolitan statistical areas (MSAs) with substantial immigrant populations, we find that, on average, 37% of an immigrant’s coworkers are themselves immigrants; in contrast, only 14% of a native-born worker’s coworkers are immigrants. We decompose this difference into the probability of working with compatriots versus with immigrants from other source countries. Using human capital, employer, and location characteristics, we narrow the mechanisms that might explain immigrant concentration. We find that industry, language, and residential segregation collectively explain almost all the excess tendency to work with immigrants from other source countries, but they have limited power to explain work with compatriots. This large unexplained compatriot component suggests an important role for unmeasured country-specific factors, such as social networks. PMID:25425452

  14. [French immigration policy].

    Science.gov (United States)

    Weil, P

    1994-01-01

    From the late nineteenth century through 1974, France permitted immigration to furnish workers and to compensate for the low level of fertility. Intense immigration from North Africa, the economic crisis of the 1970s, and other factors led to policy changes in 1974. French immigration policy since 1974 has fluctuated between guaranteeing foreigners equal rights regardless of their religion, race, culture, or national origin, and attempting to differentiate among immigrants depending on their degree of assimilability to French culture. From 1974 to 1988, France had five different policies regarding whether to permit new immigration and what to do about illegal immigrants. In July 1984, the four major political parties unanimously supported a measure in Parliament that definitively guaranteed the stay in France of legal immigrants, whose assimilation thus assumed priority. Aid for return to the homeland was no longer to be widely offered, and immigration of unskilled workers was to be terminated except for those originating in European Community countries. Major changes of government in 1988 and 1993 affected only the modalities of applying these principles. The number of immigrants has fluctuated since 1974. Unskilled workers, the only category whose entrance was specifically controlled by the 1984 measures, have declined from 174,000 in 1970 to 25,000 in the early 1990s. The number of requests for political asylum declined from 60,000 in 1989 to 27,000 in 1993, and in 1991, 15,467 persons were granted refugee status. The number of immigrants of all types permitted to remain in France declined from 250,000 or 3000 per year in the early 1970s to around 110,000 at present. Although the decline is significant, it appears insufficient to the government in power since 1993. Although migratory flows are often explained as the product of imbalance in the labor market or in demographic growth, the French experience suggests that government policies, both in the sending and

  2. Refugee children's sandplay narratives in immigration detention in Canada.

    Science.gov (United States)

    Kronick, Rachel; Rousseau, Cécile; Cleveland, Janet

    2018-04-01

    Asylum seeking children arriving in Canada regularly face incarceration in medium-security-style immigration detention centres. Research demonstrates the human cost of detaining migrant children and families and the psychiatric burden linked with such imprisonment. This study aims to understand the lived experiences of children aged 3-13 held in detention. Informed by a qualitative methodology of narrative inquiry, child participants created worlds in the sand and generated stories to express their subjective experience. Results suggest that children's sandplay confirms the traumatic nature of immigration detention while also revealing children's sometimes conflicting understanding of the meaning of detention and their own migration. The results are contextualized by a description of detention conditions and the psychiatric symptoms associated with immigration incarceration. The study highlights the need for more research examining the impact of immigration detention on children's mental health, while also underlining how refugee children's voices provide important direction for policy change.

    2014-09-01

    The acculturation process is an important factor in the experience of all immigrants. Although previous studies have indicated the challenges faced by Korean immigrants, little attention has been paid to Korean women's immigration experiences. A focused ethnography was used to examine midlife and older Korean immigrant women's experiences following their immigration to Canada. Fifteen women were interviewed in a city in Western Canada. The findings showed that in coming to Canada, women focused on caring for their children and often sacrificed their personal dreams. They had to be employed to support their families, and received support from family and government. Women participated regularly in a Korean Church and drew on their Christian faith to ease their adjustment. They retained hopes for the future including good health and a better life for their children. Most women indicated that it was difficult to integrate into Canadian society but they never gave up on their adjustment to a new culture. In this manuscript, the adjustment experience of the immigrant women is discussed in the context of an acculturation framework. The findings will enhance health professionals' awareness of adjustment patterns and associated challenges to Korean immigrant women's quality of life.

    2005-01-01

    For the most part, immigrants in the United States do not have access to the very safety-net benefits supported by their taxes, nor to essential due-process rights, simply because they are not citizens or legal residents. Contemporary demographics of immigration and post-9/11 security concerns have colored our traditional hospitality as a nation of immigrants and made life more difficult for immigrants. The Catholic Church has a rich history of scriptural and social teaching that addresses the question of immigration. Stories of forced migration in the Pentateuch led to commandments regarding strangers and the responsibility to be welcoming. In the New Testament, we see that the Holy Family themselves were refugees. The Gospel of St. Matthew tells us that we will be judged by the way we respond to migrants and others in need. In Exsul Familia, Pope Pius XII reaffirms the commitment of the church to care for pilgrims, aliens, exiles, and migrants. In Ecclesia in America, Pope John Paul II states that the ultimate solution to illegal immigration is the elimination of global underdevelopment and that, in the meantime, the human rights of all migrants must be respected. In 2003, the bishops of Mexico and the United States jointly issued the pastoral letter Strangers No Longer: Together on the Journey of Hope. In this letter, the bishops say that U.S. immigration policy should protect the human rights and dignity of immigrants and asylum seekers. The bishops also offer a number of proposed public policy responses toward that end. To advance the principles contained in Strangers No Longer, the bishops have decided to mount a national campaign designed to unite and mobilize a growing network of Catholic organizations and individuals, as well as others of good faith. In addition, the campaign will seek to dispel myths and misperceptions about immigrants.

  10. Obesity and Regional Immigrant Density.

    Science.gov (United States)

    Emerson, Scott D; Carbert, Nicole S

    2017-11-24

    Canada has an increasingly large immigrant population. Areas of higher immigrant density, may relate to immigrants' health through reduced acculturation to Western foods, greater access to cultural foods, and/or promotion of salubrious values/practices. It is unclear, however, whether an association exists between Canada-wide regional immigrant density and obesity among immigrants. Thus, we examined whether regional immigrant density was related to obesity, among immigrants. Adult immigrant respondents (n = 15,595) to a national population-level health survey were merged with region-level immigrant density data. Multi-level logistic regression was used to model the odds of obesity associated with increased immigrant density. The prevalence of obesity among the analytic sample was 16%. Increasing regional immigrant density was associated with lower odds of obesity among minority immigrants and long-term white immigrants. Immigrant density at the region-level in Canada may be an important contextual factor to consider when examining obesity among immigrants.

They hold that nationality should play a normative role in this regard, and that this is necessary in order to justify restrictions...... on immigration. The present chapter discusses the envisaged role for considerations of nationality with regard to admission and residence, and examines the actual implications of arguments advanced by liberal nationalists as to why nationality should play this role.

    Full Text Available In this paper I investigate the libertarian account of immigration. In the first section I distinguish between right-libertarianism and left-libertarianism. In the second section I analyze the arguments focused on immigration from the perspective of self-ownership focused on Nozick’s case and Steiner’s analogy. In the third section I discuss the conflict between the collective consent on the issue of immigration and the individuals’ decision. The conclusion sets the libertarian framework as being flawed in its argumentation on the issue of immigration because it fails to provide strong arguments about the fact that the individuals are free to choose to open or close the borders.

    Using a database that includes the universe of individuals and establishments in Denmark over the period 1991-2008 we analyze the effect of a large inflow of non-European (EU) immigrants on Danish workers. We first identify a sharp and sustained supply-driven increase in the inflow of non......-EU immigrants in Denmark, beginning in 1995 and driven by a sequence of international events such as the Bosnian, Somalian and Iraqi crises. We then look at the response of occupational complexity, job upgrading and downgrading, wage and employment of natives in the short and long run. We find...... that the increased supply of non-EU low skilled immigrants pushed native workers to pursue more complex occupations. This reallocation happened mainly through movement across firms. Immigration increased mobility of natives across firms and across municipalities but it did not increase their probability...

While native children face yearly poverty risks of less than 10 percent in all three countries and for all years studied the increasing proportion of immigrant children...... with an origin in middle- and low-income countries have poverty risks that vary from 38 up to as much as 58 percent. At the end of the observation period, one third of the poor children in Norway and as high as about a half in Denmark and in Sweden are of immigrant origin. The strong overrepresentation...... of immigrant children from low- and middle-income countries when measured in yearly data is also found when applying a longer accounting period for poverty measurement. We find that child poverty rates are generally high shortly after arrival to the new country and typically decrease with years since...

    Henglein, Fritz; Nielsen, Lasse

    2011-01-01

    We present a new sound and complete axiomatization of regular expression containment. It consists of the conventional axiomatiza- tion of concatenation, alternation, empty set and (the singleton set containing) the empty string as an idempotent semiring, the fixed- point rule E* = 1 + E × E......* for Kleene-star, and a general coin- duction rule as the only additional rule. Our axiomatization gives rise to a natural computational inter- pretation of regular expressions as simple types that represent parse trees, and of containment proofs as coercions. This gives the axiom- atization a Curry......-Howard-style constructive interpretation: Con- tainment proofs do not only certify a language-theoretic contain- ment, but, under our computational interpretation, constructively transform a membership proof of a string in one regular expres- sion into a membership proof of the same string in another regular expression.

  19. Supersymmetric dimensional regularization

    International Nuclear Information System (INIS)

    Siegel, W.; Townsend, P.K.; van Nieuwenhuizen, P.

    1980-01-01

    There is a simple modification of dimension regularization which preserves supersymmetry: dimensional reduction to real D < 4, followed by analytic continuation to complex D. In terms of component fields, this means fixing the ranges of all indices on the fields (and therefore the numbers of Fermi and Bose components). For superfields, it means continuing in the dimensionality of x-space while fixing the dimensionality of theta-space. This regularization procedure allows the simple manipulation of spinor derivatives in supergraph calculations. The resulting rules are: (1) First do all algebra exactly as in D = 4; (2) Then do the momentum integrals as in ordinary dimensional regularization. This regularization procedure needs extra rules before one can say that it is consistent. Such extra rules needed for superconformal anomalies are discussed. Problems associated with renormalizability and higher order loops are also discussed

    2015-01-01

    In this paper we investigate the usage of regularized correntropy framework for learning of classifiers from noisy labels. The class label predictors learned by minimizing transitional loss functions are sensitive to the noisy and outlying labels of training samples, because the transitional loss functions are equally applied to all the samples. To solve this problem, we propose to learn the class label predictors by maximizing the correntropy between the predicted labels and the true labels of the training samples, under the regularized Maximum Correntropy Criteria (MCC) framework. Moreover, we regularize the predictor parameter to control the complexity of the predictor. The learning problem is formulated by an objective function considering the parameter regularization and MCC simultaneously. By optimizing the objective function alternately, we develop a novel predictor learning algorithm. The experiments on two challenging pattern classification tasks show that it significantly outperforms the machines with transitional loss functions.

    Full Text Available Opinion surveys on attitudes towards immigration are becoming more and more important, owing to the increasing role of political debate on migration issues in Western European countries. CNR has conducted four surveys on this topic, collecting data on the evolution of Italians attitudes towards migration issues. In fact, the ? rst survey was conducted in the second half of the eighties, when foreign immigration was in its early stages. The last survey took place in 2002, when immigration was already well established in Italy. The article focuses on three main issues: the global impact of immigration on Italian society, the immigrants role in the labour market, and immigration policy. In general, the results of the last survey con? rm a trend that appeared already in 1997, of more balanced and realistic opinion that were less of a response to circumstances perceived as special emergencies. Highly educated people, teachers and students continue to be the most open and receptive groups, whereas the less favourably inclined and more worried continue to be old people, those with less education, the unemployed, housewives, and retirees.

Does it make any difference if an immigrant is Asian or White? When Vietnamese immigrants are compared to East European immigrants, Vietnamese men earn 7-9% less than comparable East European men, with more discrimination among the less educated, and in the larger Vietnamese population centers like California. Vietnamese women earn as much as comparable East European women. Vietnamese immigrants, male and female, are much less likely to hold managerial and supervisory positions than comparable East European immigrants.

    Li, Hongliang; Liu, Derong; Wang, Ding

    2018-04-01

    This paper introduces a novel manifold regularized reinforcement learning scheme for continuous Markov decision processes. Smooth feature representations for value function approximation can be automatically learned using the unsupervised manifold regularization method. The learned features are data-driven, and can be adapted to the geometry of the state space. Furthermore, the scheme provides a direct basis representation extension for novel samples during policy learning and control. The performance of the proposed scheme is evaluated on two benchmark control tasks, i.e., the inverted pendulum and the energy storage problem. Simulation results illustrate the concepts of the proposed scheme and show that it can obtain excellent performance.

  12. Effects of individual immigrant attitudes and host culture attitudes on doctor-immigrant patient relationships and communication in Canada.

    In many countries doctors are seeing an increasing amount of immigrant patients. The communication and relationship between such groups often needs to be improved, with the crucial factor potentially being the basic attitudes (acculturation orientations) of the doctors and patients. This study therefore explores how acculturation orientations of Canadian doctors and immigrant patients impact the doctor-patient relationship. N = 10 participants (five doctors, five patients) participated in acculturation orientation surveys, video recordings of a regular clinic visit, and semi structured interviews with each person. Acculturation orientations were calculated using the Euclidean distance method, video recordings were analyzed according to the Verona Coding System, and thematic analysis was used to analyze the interviews. Interviews were used to explain and interpret the behaviours observed in the video recordings. The combined acculturation orientations of each the doctor and immigrant patient played a role in the doctor-patient relationship, although different combinations than expected produced working relationships. Video recordings and interviews revealed that these particular immigrant patients were open to adapting to their new society, and that the doctors were generally accepting of the immigrants' previous culture. This produced a common level of understanding from which the relationship could work effectively. A good relationship and level of communication between doctors and immigrant patients may have its foundation in acculturation orientations, which may affect the quality of care, health behaviours and quality of life of the immigrant. The implications of these findings are more significant when considering effective interventions to improve the quality of doctor-patient relationships, which should have a solid foundational framework. Our research suggests that interventions based on understanding the influence of acculturation orientations could

    Currently there are high expectations for the introduction of policies related to diverse regular employees. These policies are a response to the problem of disparities between regular and non-regular employees (part-time, temporary, contract and other non-regular employees) and will make it more likely that workers can balance work and their private lives while companies benefit from the advantages of regular employment. In this paper, I look at two issues that underlie this discussion. The ...

    2014-04-17

    Learning ranking scores is critical for the multimedia database retrieval problem. In this paper, we propose a novel ranking score learning algorithm by exploring the sparse structure and using it to regularize ranking scores. To explore the sparse structure, we assume that each multimedia object could be represented as a sparse linear combination of all other objects, and combination coefficients are regarded as a similarity measure between objects and used to regularize their ranking scores. Moreover, we propose to learn the sparse combination coefficients and the ranking scores simultaneously. A unified objective function is constructed with regard to both the combination coefficients and the ranking scores, and is optimized by an iterative algorithm. Experiments on two multimedia database retrieval data sets demonstrate the significant improvements of the propose algorithm over state-of-the-art ranking score learning algorithms.

    2010-01-01

    The optimization of large portfolios displays an inherent instability due to estimation error. This poses a fundamental problem, because solutions that are not stable under sample fluctuations may look optimal for a given sample, but are, in effect, very far from optimal with respect to the average risk. In this paper, we approach the problem from the point of view of statistical learning theory. The occurrence of the instability is intimately related to over-fitting, which can be avoided using known regularization methods. We show how regularized portfolio optimization with the expected shortfall as a risk measure is related to support vector regression. The budget constraint dictates a modification. We present the resulting optimization problem and discuss the solution. The L2 norm of the weight vector is used as a regularizer, which corresponds to a diversification 'pressure'. This means that diversification, besides counteracting downward fluctuations in some assets by upward fluctuations in others, is also crucial because it improves the stability of the solution. The approach we provide here allows for the simultaneous treatment of optimization and diversification in one framework that enables the investor to trade off between the two, depending on the size of the available dataset.

    Full Text Available Immigration constitutes an all time and multi-dimensional social phenomenon. There are quite a few people that in every time period seek a new place of residence and employment, in order to be able to survive or get a better life. The causes which lead to immigration are various and the immigration itself affects not only the immigrants but also the countries of departure and arrival. The immigration phenomenon has occupied and continues to occupy the majority of countries, among which is Greece which has been one of the new host countries for immigrants. The moving of the population presents when the social and economic environment in which an individual lives and moves, does not provide him with the capability to fulfill his pursuits and satisfy his ambitions. The most frequent reason of immigration nowadays is the economic factor and the objective of the individual that immigrates is finding work. In the present project we will study unemployment and employment in the host countries and more specifically in Greece. In Greece during the last years there appears to be an intense influx of immigrants converting it from a departure country to a host country for immigrants. What happens with the working conditions and insurance, how does immigration affect the unemployment of the permanent population, in what kind of jobs are immigrants occupied and do age and sex play a role in finding work? These are some of the questions we are called to answer through this project. The project not only will deal with how immigration affects the working market but also the economy in general (Cholezas and Tsakloglou, 2008. The research part of the project is based on the Greek and European Statistics Service. The statistical data are presented in the form of charts and diagrams.

    Full Text Available Objective: The main objective of this study is to define and operationalize the concept of immigrant capital, a key factor that differentiates immigrant from host country entrepreneurs in how they recognize and start new ventures. Research Design & Methods: A detailed analysis of contemporary immigrant entrepreneurship and opportunity recognition literature was carried out. Using grounded theory, we synthesized the outcomes from the analysis of eight Canadian and U.S. case studies of successful immigrant entrepreneurs with the key findings from the literature to define and develop a model of immigrant capital. Findings: Based on our grounded theory development process we show that the concept of immigrant capital as a distillate of human, cultural, economic and social capital that goes beyond expected opportunity recognition (OR drivers like prior knowledge and prior experience to differentiate and enhance the immigrant entrepreneur’s ability to recognize business opportunities compared to host country entrepreneurs. We found immigrant capital to be a consequence of being boundary spanners in host and home country networks. Implications & Recommendations: Understanding a unique resource like immigrant capital, will help immigrant as well as host country entrepreneurs further develop their opportunity recognition ability by bridging gaps and fulfilling the needs for both, immigrant and host country consumers. Contribution & Value Added: The main contribution is the theoretical development, identification and definition of the immigrant capital model and propositions that will articulate the factors that lead to the conceptualization and operationalization of immigrant capital. Furthermore, the immigrant capital model can serve host country entrepreneurs to develop cross-cultural networks and jump-start entrepreneurial activities in their home countries as well as learn how to expand their operations into global markets.

    Changing population demographics and immigration patterns have resulted in increasing numbers of Canadians who report speaking a language other than French or English. Inclusion of English-as-a-second-language (ESL) immigrants in cancer education research is critical if disparities in access and use of preventive health care services are to be addressed. This article describes the challenges experienced recruiting and interviewing older ESL immigrant women for a colon cancer prevention study. Factors influencing the recruitment and interview of ESL immigrant women were identified through regular team meetings, interviews, and reflective practice notes. Issues included the importance of community contacts, language barriers, and the motivations of the women for participating. Recommendations for recruitment and inclusion of ESL immigrants in cancer education research are provided.

  13. Portrayal of Immigrants in Newsmagazines

    Goran Goldberger

    2004-03-01

    Full Text Available This article analyzes how United States newsmagazines represented immigrants in the aftermath of September 11th terrorist attacks. Methodologically, the paper uses the frame analysis from a social constructivist standpoint, identifying the four functions of frame, as defined by Entman. Three months prior to the attacks, newsmagazines framed immigrants as “needed” and, in most cases, they portrayed them positively. In the period after the attacks, the frame shifted and newsmagazines started representing immigrants as “feared”, potential harborers of terrorists, and so on. Before the attacks, illegal immigrants were represented as the greatest immigration problem. After the attacks, the attention of newsmagazines shifted to legal immigrants with terrorist intentions. The results suggest that the issue of immigrants and immigration policy in the media collided with the threat of terrorism as a foreign policy issue. Thus, it became a security issue that influenced the representation of immigrants. In newsmagazines’ portrayal of immigrants, political features became more prominent than economic ones.

    Immigrants often lose their health advantage as they start adapting to the ways of the new society. Having access to care when it is needed is one way that individuals can maintain their health. We assessed the healthcare access in Canadian immigrants and the socioeconomic factors associated with access over a 12-year period. We compared two measures of healthcare access (having a regular doctor and reporting an unmet healthcare need in the past 12 months) among immigrants and Canadian-born men and women, aged more than 18 years. We applied a logistic random effects model to evaluate these outcomes separately, in 3081 males and 4187 females from the National Population Health Survey (1994-2006). Adjusting for all covariates, immigrant men and women (white and non-white) had similar odds of having a regular doctor than the Canadian-born individuals (white immigrants: males OR: 1.32, 95% C.I.: 0.89-1.94, females OR: 1.14, 95% C.I.: 0.78-1.66; non-white immigrants: males OR: 1.28, 95% C.I.: 0.73-2.23, females OR: 1.23, 95% C.I.: 0.64-2.36). Interestingly, non-white immigrant women had significantly fewer unmet health needs (OR: 0.32, 95% C.I.: 0.17-0.59). Among immigrants, time since immigration was associated with having access to a regular doctor (OR per year: 1.02, 95% C.I.: 1.00-1.04). Visible minority female immigrants were least likely to report an unmet healthcare need. In general, there is little evidence that immigrants have worse access to health-care than the Canadian-born population. © 2010 Blackwell Publishing Ltd.

    "Regularity of Minimal Surfaces" begins with a survey of minimal surfaces with free boundaries. Following this, the basic results concerning the boundary behaviour of minimal surfaces and H-surfaces with fixed or free boundaries are studied. In particular, the asymptotic expansions at interior and boundary branch points are derived, leading to general Gauss-Bonnet formulas. Furthermore, gradient estimates and asymptotic expansions for minimal surfaces with only piecewise smooth boundaries are obtained. One of the main features of free boundary value problems for minimal surfaces is t

    analysis, and vests the executive with appropriate discretion in administering the law. The paper also argues that the United States should anticipate and accommodate the needs of persons compelled to migrate by its military, trade, development, and other commitments. In addition, the US immigration system needs to be able to distinguish between undocumented immigrants, and refugees and asylum seekers, and to treat these two populations differently. The paper assumes that there will be continued bipartisan support for immigration enforcement. However, even with a strong enforcement apparatus in place and an adaptable, coherent, evidence-based legal immigration system that closely aligns with US interests, some (reduced level of illegal migration will persist. The paper offers a sweeping, historical analysis of how this population emerged, why it has grown and contracted, and how estimates of its size have been politically exploited. Legalization is often viewed as the third rail of immigration reform. Yet, Congress has regularly legalized discrete undocumented populations, and the combination of a well-structured legalization program, strengthened legal immigration system, and strong enforcement policies can prevent the reemergence of a large-scale undocumented population. In contrast, the immense US enforcement apparatus will work at cross-purposes to US interests and values, absent broader reform. The paper ends with a series of recommendations to reform the legal immigration system, downsize the current undocumented population, and ensure its permanent reduction. It proposes that the United States “reissue” (or reuse the visas of persons who emigrate, as a way to promote legal immigration reform without significantly increasing annual visa numbers. [1] Effective legal immigration policies constitute the cornerstone of reform because, without them, the immigration enforcement system and any eventual legalization program will not be able to deliver on their promises

    Study disparities in lifestyle habits and health characteristics of Canadian born population and immigrants with different duration of residence. Data are extracted from 2009 to 2010 public use micro-data files of Canadian Community Health Survey representing about 1.5 million people. Sixty-one percent of the study sample was born in Canada; 49 % males and 59 % below age 50. Amongst lifestyle habits, recent immigrants were less likely to be regular smokers, RR (95 % CI) 0.56 (0.36-0.88) and frequent consumers of alcohol 0.49 (0.27-0.89), but more likely to consume less fruits and vegetables 1.26 (1.04-1.53) than those born in Canada. Amongst health related factors, recent immigrants were less likely to be overweight 0.79 (0.62-0.99) and suffer from chronic diseases 0.59 (0.44-0.80), but more likely to have limited access to family medicine 1.24 (1.04-1.47) than Canada-born population. Immigration status is an important population characteristic which influenced distribution of health indicators. Prevention and promotion strategies should consider immigration status as an exposure variable in the development and implementation of public health programs.

    The incidence of tuberculosis worldwide is declining. However, in Western countries this decline is slower due to the impact of immigration. Tuberculosis in the immigrant population is related to health status in the country of origin and with overcrowding and poverty conditions in the host country. Immigrants with tuberculosis are younger, have a higher prevalence of extrapulmonary forms, greater proportion of drug resistance and higher treatment default rates than those of natives. New molecular techniques not only reduce diagnostic delay time but also allow the rapid identification of resistances and improve knowledge of transmission patterns. It is necessary to implement measures to improve treatment compliance in this population group like facilitating access to health card, the use of fixed-dose combination drugs, the participation of cultural mediators and community health workers and gratuity of drugs.

    1986-11-01

    Immigration to Venezuela is examined using census data with the focus on the period 1971-1981. A brief overview of trends since the beginning of the twentieth century is first presented. The analysis indicates that "immigration to Venezuela is clearly of a short-term nature. Flows follow job opportunities and adjust to the labour market and to the financial capacity of the exchange market. The large increase of migratory movements to Venezuela in the 1970's is characterized by a diversification of their places of origin and by a greater instability. To a large extent, the migrants are illegal, especially those coming from Colombia and the Caribbean islands. Because of the crisis of the early 1980's, which is now worsened by the down trend of both oil prices and the U.S. dollar, Venezuela has become less attractive to immigrants, particularly from neighbouring countries." The authors observe that migrants in Venezuela are not well integrated and may depart, disrupting the labor supply in certain technical and specialized occupations (SUMMARY IN ENG AND SPA) excerpt

  14. Selection of regularization parameter for l1-regularized damage detection

    Science.gov (United States)

    Hou, Rongrong; Xia, Yong; Bao, Yuequan; Zhou, Xiaoqing

    2018-06-01

    The l1 regularization technique has been developed for structural health monitoring and damage detection through employing the sparsity condition of structural damage. The regularization parameter, which controls the trade-off between data fidelity and solution size of the regularization problem, exerts a crucial effect on the solution. However, the l1 regularization problem has no closed-form solution, and the regularization parameter is usually selected by experience. This study proposes two strategies of selecting the regularization parameter for the l1-regularized damage detection problem. The first method utilizes the residual and solution norms of the optimization problem and ensures that they are both small. The other method is based on the discrepancy principle, which requires that the variance of the discrepancy between the calculated and measured responses is close to the variance of the measurement noise. The two methods are applied to a cantilever beam and a three-story frame. A range of the regularization parameter, rather than one single value, can be determined. When the regularization parameter in this range is selected, the damage can be accurately identified even for multiple damage scenarios. This range also indicates the sensitivity degree of the damage identification problem to the regularization parameter.

  15. Ensemble manifold regularization.

    Science.gov (United States)

    Geng, Bo; Tao, Dacheng; Xu, Chao; Yang, Linjun; Hua, Xian-Sheng

    2012-06-01

    We propose an automatic approximation of the intrinsic manifold for general semi-supervised learning (SSL) problems. Unfortunately, it is not trivial to define an optimization function to obtain optimal hyperparameters. Usually, cross validation is applied, but it does not necessarily scale up. Other problems derive from the suboptimality incurred by discrete grid search and the overfitting. Therefore, we develop an ensemble manifold regularization (EMR) framework to approximate the intrinsic manifold by combining several initial guesses. Algorithmically, we designed EMR carefully so it 1) learns both the composite manifold and the semi-supervised learner jointly, 2) is fully automatic for learning the intrinsic manifold hyperparameters implicitly, 3) is conditionally optimal for intrinsic manifold approximation under a mild and reasonable assumption, and 4) is scalable for a large number of candidate manifold hyperparameters, from both time and space perspectives. Furthermore, we prove the convergence property of EMR to the deterministic matrix at rate root-n. Extensive experiments over both synthetic and real data sets demonstrate the effectiveness of the proposed framework.

    The objective of this study is to investigate the relationship between immigration status and the patient experience of health care, diabetes self-management, and clinical outcomes among Mexican immigrants with diabetes receiving health care in two immigration sanctuary cities. We used data from the Immigration, Culture and Health Care study, a cross-sectional survey and medical record study of low-income patients with diabetes recruited from public hospitals and community clinics in the San Francisco Bay Area and Chicago. Undocumented Mexican, documented Mexican immigrants, and US-born Mexican-Americans' health care experiences, diabetes self-management, and clinical outcomes were compared using multivariate linear and logistic regressions. We found no significant differences in reports of physician communication, or in measures of diabetes management between undocumented and documented immigrants. All three groups had similar clinical outcomes in glycemic, systolic blood pressure, and lipid control. These results indicate that, at least in some settings, undocumented Mexican immigrants with diabetes can achieve similar clinical outcomes and report similar health care experiences as documented immigrants and US-born Mexican-Americans.

The author argues that "the growth of this immigrant niche resulted from changes in the relative supply of native workers and in the structure of employment, which opened the bureaucracy to immigrants and reduced native/immigrant competition. These shifts opened hiring portals; given the advantages of network hiring for workers and managers, and an immigrant propensity for government employment, network recruitment led to a rapid buildup in immigrant ranks." excerpt

    2013-07-01

    Rates of human migration are steadily rising and have resulted in significant sociopolitical debates over how to best respond to increasing cultural diversity and changing migration patterns. Research on prejudicial attitudes toward immigrants has focused on the attitudes and beliefs that individuals in the receiving country hold about immigrants. The current study enhances this literature by examining how young adults view authorized and unauthorized immigrants and refugees. Using a between-groups design of 191 undergraduates, we found that participants consistently reported more prejudicial attitudes, greater perceived realistic threats, and greater intergroup anxiety when responding to questions about unauthorized compared with authorized immigrants. Additionally, there were differences in attitudes depending on participants' generational status, with older-generation participants reporting greater perceived realistic and symbolic threat, prejudice, and anxiety than newer-generation students. In some instances, these effects were moderated by participant race/ethnicity and whether they were evaluating authorized or unauthorized immigrants. Lastly, perceived realistic threat, symbolic threat, and intergroup anxiety were significant predictors of prejudicial attitudes. Overall, participants reported positive attitudes toward refugees and resettlement programs in the United States. These findings have implications for future research and interventions focused on immigration and prejudice toward migrant groups. PsycINFO Database Record (c) 2013 APA, all rights reserved.

I found immigrant children's math and science achievement to be lower than the others only in England, the U.S., and Canada. Non-English language background was found in each country to relate to poor math and science learning and this disadvantage was stronger among native-born children—presumably children of indigenous groups—than among immigrant children. I also examined the school variation in math performance gaps, using hierarchical linear modeling (HLM to each country's data. The patterns in which language- and generation-related math achievement gaps varied between schools are different in the five countries.

  18. Immigrant Women and Partner Violence

    OpenAIRE

    Violence against women is a global problem, which can be recognized in every society and culture. Both in Canada and Finland the research about violence against immigrant women has begun quite recently and therefore, there is still a lot we do not know about this phenomenon and thus a demand for research. Immigrant women face unique circumstances and are in a vulnerable position of being abused. They are not a homogeneous group, on the contrary, they have individual life experiences but they ...

    2009-01-01

    Economists are often puzzled by the stronger public opposition to immigration than trade, since the two policies have symmetric effects on wages. Unlike trade, however, immigration changes the composition of the local population, imposing potential externalities on natives. While previous studies have focused on fiscal spillovers, a broader class of externalities arise because people value the "compositional amenities" associated with the characteristics of their neighbors and co-workers.

  20. Chinese Immigrant Wealth: Heterogeneity in Adaptation

    2016-01-01

    Chinese immigrants are a diverse and growing group whose members provide a unique opportunity to examine within-immigrant group differences in adaptation. In this paper, we move beyond thinking of national-origin groups as homogenous and study variation among Chinese immigrants in wealth ownership, a critical indicator of adaptation that attracts relatively little attention in the immigration literature. We develop an analytical approach that considers national origin, tenure in the U.S., and age to examine heterogeneity in economic adaptation among the immigrant generation. Our results show that variations among Chinese immigrants explain within-group differences in net worth, asset ownership, and debt. These differences also account for important variation between Chinese immigrants, natives, and other immigrant groups and provide important, new insight into the processes that lead to immigrant adaptation and long-term class stability.

    Chan Huesum; Halpern, M.B.

    1987-01-01

    The recent continuum regularization of d-dimensional Euclidean gravity is generalized to arbitrary power-law measure and studied in some detail as a representative example of coordinate-invariant regularization. The weak-coupling expansion of the theory illustrates a generic geometrization of regularized Schwinger-Dyson rules, generalizing previous rules in flat space and flat superspace. The rules are applied in a non-trivial explicit check of Einstein invariance at one loop: the cosmological counterterm is computed and its contribution is included in a verification that the graviton mass is zero.

    "Building on arguments made by Grasmuck and Pessar (1991), Hardy-Fanta (1993), and Hondagneu-Sotelo (1994), among others, this article makes the case for a gendered understanding of immigrant political socialization. Looking at recent Latin American immigrants to New York City, the article argues that immigrant Latino men are more likely to favor continuity in patterns of socialization and organization, and immigrant Latinas are more likely to favor change. This finding helps bridge theoretical and empirical literatures in immigration studies, applying the logic of gender-differentiated decisionmaking to the area of immigrant political socialization and behavior." excerpt

  8. Immigration Adjudication: The Missing “Rule of Law”

    2017-04-01

    Full Text Available The United States spends more than $19 billion each year on border and immigration enforcement.[1] The Obama administration removed more people in eight years than the last four administrations combined.[2] Yet, to the Trump administration, enforcement is not yet robust enough. Among other measures, the administration favors more expedited and summary removals. More than 80 percent[3] of all removal orders are already issued outside the court process: When the Department of Homeland Security (DHS uses summary removal processes, both access to counsel and an immigration judge can be nearly impossible. Advocates and policy analysts are equally concerned that a backlog of over 545,000 immigration court cases creates delay that harm people seeking asylum and other humanitarian protection. Recent use of priority or “rocket” dockets in immigration court and lack of appointed counsel also interfere with the fair adjudication of claims. Thus the administrative removal system is criticized both for being inefficient and moving too slowly, on the one hand, and for moving too quickly without adequate procedural safeguards, on the other. Both critiques have merit. The challenge is to design, implement, and most critically, maintain an appropriately balanced adjudication system. While it is clear that US removal procedures need reform, process alone will not be able to address some of the systematic flaws within the system. Ultimately, the DHS will need to refine and prioritize the cases that are placed into the system and the government needs new tools, widely used in other adjudication systems, that can reduce backlogs, incentivize cooperation, and facilitate resolution. Congress should similarly reexamine the barriers to status and avenues for regularization or preservation of status. The paucity of equitable forms or relief and the lack of statutes of limitation place stress on the immigration court system. The lack of appointed counsel has a

Under the assumption of spherical symmetry, there is a particular class of solutions that correspond to regular charged black holes whose interior region is de Sitter, the exterior region is Reissner-Nordstroem and there is a charged thin-layer in-between the two. The main physical and geometrical properties of such charged regular black holes are analyzed.

    Full Text Available Abstract Background Immigration is increasing in Italy. In 2003, 2.6 million foreign citizens lived in the country; 52% were men and the majority were young adults who migrated for work. The purpose of this study was to investigate differences in hospitalisation between immigrants and the resident population during the year 2000 in the Lazio region. Methods Hospital admissions of immigrants from Less Developed Countries were compared to those of residents. We measured differences in hospitalisation rates and proportions admitted. Results Adult immigrants have lower hospitalisation rates than residents (134.6 vs. 160.5 per thousand population for acute care; 26.4 vs. 38.3 for day care. However, hospitalisation rates for some specific causes (injuries, particularly for men, infectious diseases, deliveries and induced abortions, ill-defined conditions were higher for immigrants than for residents. Immigrants under 18 years seem to be generally healthy; causes of admission in this group are similar to those of residents of the same age (respiratory diseases, injuries and poisoning. The only important differences are for infectious and parasitic diseases, with a higher proportion among immigrant youths. Conclusion The low hospitalisation rates for foreigners may suggest that they are a population with good health status. However, critical areas, related to poor living and working conditions and to social vulnerability, have been identified. Under-utilisation of services and low day care rates may be partially due to administrative, linguistic, and cultural barriers. As the presence of foreigners becomes an established phenomenon, it is important to evaluate their epidemiological profile, develop instruments to monitor and fulfil their specific health needs and plan health services for a multi-ethnic population.

    2013-06-01

    Estimation of high-dimensional covariance matrices is known to be a difficult problem, has many applications, and is of current interest to the larger statistics community. In many applications including so-called the "large p small n " setting, the estimate of the covariance matrix is required to be not only invertible, but also well-conditioned. Although many regularization schemes attempt to do this, none of them address the ill-conditioning problem directly. In this paper, we propose a maximum likelihood approach, with the direct goal of obtaining a well-conditioned estimator. No sparsity assumption on either the covariance matrix or its inverse are are imposed, thus making our procedure more widely applicable. We demonstrate that the proposed regularization scheme is computationally efficient, yields a type of Steinian shrinkage estimator, and has a natural Bayesian interpretation. We investigate the theoretical properties of the regularized covariance estimator comprehensively, including its regularization path, and proceed to develop an approach that adaptively determines the level of regularization that is required. Finally, we demonstrate the performance of the regularized estimator in decision-theoretic comparisons and in the financial portfolio optimization setting. The proposed approach has desirable properties, and can serve as a competitive procedure, especially when the sample size is small and when a well-conditioned estimator is required.

    An overview of the continuum regularization program is given. The program is traced from its roots in stochastic quantization, with emphasis on the examples of regularized gauge theory, the regularized general nonlinear sigma model and regularized quantum gravity. In its coordinate-invariant form, the regularization is seen as entirely geometric: only the supermetric on field deformations is regularized, and the prescription provides universal nonperturbative invariant continuum regularization across all quantum field theory. 54 refs

    U.S. immigrants have faced a changing landscape with regard to immigration enforcement over the last two decades. Following the passage of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996, and the creation of the Immigration and Customs Enforcement (ICE) agency after the attacks of September 11, 2001, detention and deportation activity increased substantially. As a result, immigrants today are experiencing heightened fear of profiling and deportation. Little research exists on how these activities affect the health and well-being of U.S. immigrant communities. This study sought to address this gap by using community-based participatory research to investigate the impact of enhanced immigration enforcement on immigrant health in Everett, Massachusetts, USA, a city with a large and diverse immigrant population. Community partners and researchers conducted 6 focus groups with 52 immigrant participants (documented and undocumented) in five languages in May 2009. The major themes across the groups included: 1) Fear of deportation, 2) Fear of collaboration between local law enforcement and ICE and perception of arbitrariness on the part of the former and 3) Concerns about not being able to furnish documentation required to apply for insurance and for health care. Documented and undocumented immigrants reported high levels of stress due to deportation fear, which affected their emotional well-being and their access to health services. Recommendations from the focus groups included improving relationships between immigrants and local police, educating immigrants on their rights and responsibilities as residents, and holding sessions to improve civic engagement. Immigration enforcement activities and the resulting deportation fear are contextual factors that undermine trust in community institutions and social capital, with implications for health and effective integration processes.

    International Nuclear Information System (INIS)

    2000-01-01

    The theory of metric regularity is an extension of two classical results: the Lyusternik tangent space theorem and the Graves surjection theorem. Developments in non-smooth analysis in the 1980s and 1990s paved the way for a number of far-reaching extensions of these results. It was also well understood that the phenomena behind the results are of metric origin, not connected with any linear structure. At the same time it became clear that some basic hypotheses of the subdifferential calculus are closely connected with the metric regularity of certain set-valued maps. The survey is devoted to the metric theory of metric regularity and its connection with subdifferential calculus in Banach spaces

    In this paper, we propose a manifold regularized correlation tracking method with augmented samples. To make better use of the unlabeled data and the manifold structure of the sample space, a manifold regularization-based correlation filter is introduced, which aims to assign similar labels to neighbor samples. Meanwhile, the regression model is learned by exploiting the block-circulant structure of matrices resulting from the augmented translated samples over multiple base samples cropped from both target and nontarget regions. Thus, the final classifier in our method is trained with positive, negative, and unlabeled base samples, which is a semisupervised learning framework. A block optimization strategy is further introduced to learn a manifold regularization-based correlation filter for efficient online tracking. Experiments on two public tracking data sets demonstrate the superior performance of our tracker compared with the state-of-the-art tracking approaches.

    2009-01-01

    Full Text Available In the year 2000, Romanians barely figured in statistics for immigration into Spain, but since then it is the immigrant community that has grown most rapidly. By January 2007, this community had become the second-largest in terms of numbers (after that of the Moroccan community. The intensity of this migration flow has resulted from what has taken place in Romania since the mid-1990s, as well as from the characteristics of the Spanish labour market. Though Romanian immigration has mainly taken place through irregular channels, this has not prevented them from achieving access to the labour market, given that Spain’s “black economy” is large enough to easily absorb irregular immigration. Furthermore, the social network created between Romanian immigrants has encouraged the intensity of the migration flow, even though it is a network which – beyond the most direct family links – is extremely weak, at least for the largest sector of Romanian immigration (minorities such as gypsies and members of religious orders have very extensive, binding social networks. Thus, the job placement of the largest sector has been determined by their initial incorporation onto the “informal economy”, a fact that has meant that they have mainly been doing lowskilled jobs; nevertheless, they have now achieved a significant presence in skilled employment, and this trend is expected to continue in the future.

    Dimensional regularization is introduced in configuration space by Fourier transforming in D-dimensions the perturbative momentum space Green functions. For this transformation, Bochner theorem is used, no extra parameters, such as those of Feynman or Bogoliubov-Shirkov are needed for convolutions. The regularized causal functions in x-space have ν-dependent moderated singularities at the origin. They can be multiplied together and Fourier transformed (Bochner) without divergence problems. The usual ultraviolet divergences appear as poles of the resultant functions of ν. Several example are discussed. (author). 9 refs

    To assess parenting stress and major difficulties experienced in early motherhood among immigrant and Taiwanese women in Pingtung, southern Taiwan. A comparative, descriptive, cohort study of parenting stress and maternal psychological health, using the Child Care Stress Checklist and Edinburgh Postpartum Depression Scale. A purposive sample of 26 foreign-born Vietnamese and 162 Taiwanese mothers were surveyed at 6 weeks' postpartum. Both groups of mothers experienced similar parenting difficulties including the establishment of a regular sleeping schedule for the infant, consoling a crying infant, awareness of infant's needs, conflict with family members, and difficulties managing household chores. Curtailment of social activities was reported more often by Taiwanese mothers, whereas inaccessibility to other experienced mothers and poor maternal-infant bonding were experienced more by immigrant mothers. There were significant differences between groups, with high levels of child care stress and postpartum depression symptoms reported more often by immigrant mothers. Nurses-midwives and community child health nurses need to be sensitive to the particular difficulties and stresses of parenting in mothers from different backgrounds and provide effective interventions and support activities.

  18. Throughput Analysis of Large Wireless Networks with Regular Topologies

    Full Text Available The throughput of large wireless networks with regular topologies is analyzed under two medium-access control schemes: synchronous array method (SAM and slotted ALOHA. The regular topologies considered are square, hexagon, and triangle. Both nonfading channels and Rayleigh fading channels are examined. Furthermore, both omnidirectional antennas and directional antennas are considered. Our analysis shows that the SAM leads to a much higher network throughput than the slotted ALOHA. The network throughput in this paper is measured in either bits-hops per second per Hertz per node or bits-meters per second per Hertz per node. The exact connection between the two measures is shown for each topology. With these two fundamental units, the network throughput shown in this paper can serve as a reliable benchmark for future works on network throughput of large networks.

    The prevalence of allergic conditions has been increasing worldwide, with the highest rates seen in Western countries like Canada. The development of allergies is known to be related to both genetic and environmental factors, but the causal pathways remain unclear. Studies on immigrants provide a unique opportunity to disentangle these two factors and provide a better understanding of the disease aetiology. The aim of this study was to investigate the relationship between immigration status and prevalence of non-food allergies in a population-based study of Canadians. Data of 116,232 respondents from the Canadian Community Health Survey (Cycle 3.1, 2005) were used in a multivariable logistic regression to assess the association between immigration status (non-immigrant, long-time immigrant [>10 years] and recent immigrant [≤10 years]) and self-reported doctor-diagnosed non-food allergies, adjusting for potential confounders. The highest prevalence of non-food allergies was found among non-immigrants (29.6%), followed by long-time immigrants (23.9%) and then recent immigrants (14.3%). The odds of non-food allergies were reduced by 60% (OR = 0.40, 95% CI: 0.35, 0.45) among recent immigrants and 25% (OR = 0.75, 95% CI: 0.70, 0.80) among long-time immigrants, compared with non-immigrants, after adjusting for sex, age, socio-economic status and rurality. This study finds a distinctly lower prevalence of non-food allergies among immigrants compared with non-immigrants, with the difference diminishing with longer duration of residence in Canada. The findings highlight the potential of environmental determinants of allergy development that warrant further investigation, and demonstrate the need for multicultural strategies to manage the public health burden of allergic conditions.

  11. Correlates of Social Support Among Latino Immigrants.

    Held, Mary L

    2018-04-01

    Latino immigrants encounter considerable stressors that pose risks to health and well-being during settlement in the USA. Social support serves as a protective factor that can help to buffer the negative effects of stress. Despite the importance of social support, we know little about how Latino immigrants differentially experience this protective factor. The current study analyzed data from 100 Latino immigrants residing in Tennessee. Hierarchical multiple regression analysis was employed to examine variation in self-reported social support by immigrant characteristics and immigration-related factors. Females, immigrants who are not married/cohabitating, and those who reported experiencing a greater number of discrete stressors in the USA each reported lower levels of social support. Implications for practice include an increased emphasis on assessing levels of social support and designing services to strengthen support for the most vulnerable immigrants. Future research should consider a longitudinal analysis and specific types of social support.

    Channeling phenomenon was predicted, many years ago, by stark. The first channeling experiments were performed in 1963 by Davies and his coworkers. Parallely Robinson and Oen have investigated this process by simulating trajectories of ions in monocrystals. This technique has been combined with many methods like Rutherford Backscattering Spectrometry (R.B.S.), Particles Induced X-rays Emission (P.I.X.E) and online Nuclear Reaction (N.R.A.) to localize trace elements in the crystal or to determine crystalline quality. To use channeling for material characterization we need data about the stopping power of the incident particle in the channeled direction. The ratios of channeled to random stopping powers of silicon for irradiation in the direction have been investigated and compared to the available theoretical results. We describe few applications of ion channeling in the field of materials characterization. Special attention is given to ion channeling combined with Charged Particle Activation Analysis (C.P.A.A.) for studying the behaviour of oxygen atoms in Czochralski silicon lattices under the influence of internal gettering and in different gaseous atmospheres. Association between ion channeling and C.P.A.A was also utilised for studying the influence of the growing conditions on concentration and position of carbon atoms at trace levels in the MOVPE Ga sub (1-x) Al sub x lattice. 6 figs., 1 tab., 32 refs.

    Using a new metric for generating rotating solutions, we derive in a general fashion the solution of an imperfect fluid and that of its conformal homolog. We discuss the conditions that the stress–energy tensors and invariant scalars be regular. On classical physical grounds, it is stressed that conformal fluids used as cores for static or rotating solutions are exempt from any malicious behavior in that they are finite and defined everywhere.

    Immigration involves extensive changes in living environments. Nonetheless, the predominant approach in the health science literature has been to utilize individual characteristics (including ethnic background) to explain and predict immigrants' lived experiences and health outcomes. Contexts, particularly the larger societal contexts by which immigrants are constituted, are generally ignored. Data from a critical ethnography regarding immigrants' experiences with language, occupation, and economic survival in the United States are utilized to illustrate that immigrants' lives are inseparable from the larger societal contexts, such as immigration policy, Western imperialism, and structural discrimination. The implications for practice, education, and research are discussed.

  19. Energy functions for regularization algorithms

    Delingette, H.; Hebert, M.; Ikeuchi, K.

    1991-01-01

    Regularization techniques are widely used for inverse problem solving in computer vision such as surface reconstruction, edge detection, or optical flow estimation. Energy functions used for regularization algorithms measure how smooth a curve or surface is, and to render acceptable solutions these energies must verify certain properties such as invariance with Euclidean transformations or invariance with parameterization. The notion of smoothness energy is extended here to the notion of a differential stabilizer, and it is shown that to void the systematic underestimation of undercurvature for planar curve fitting, it is necessary that circles be the curves of maximum smoothness. A set of stabilizers is proposed that meet this condition as well as invariance with rotation and parameterization.

  20. Physical model of dimensional regularization

    Energy Technology Data Exchange (ETDEWEB)

    Schonfeld, Jonathan F.

    2016-12-15

    We explicitly construct fractals of dimension 4-ε on which dimensional regularization approximates scalar-field-only quantum-field theory amplitudes. The construction does not require fractals to be Lorentz-invariant in any sense, and we argue that there probably is no Lorentz-invariant fractal of dimension greater than 2. We derive dimensional regularization's power-law screening first for fractals obtained by removing voids from 3-dimensional Euclidean space. The derivation applies techniques from elementary dielectric theory. Surprisingly, fractal geometry by itself does not guarantee the appropriate power-law behavior; boundary conditions at fractal voids also play an important role. We then extend the derivation to 4-dimensional Minkowski space. We comment on generalization to non-scalar fields, and speculate about implications for quantum gravity. (orig.)

  1. Maximum mutual information regularized classification

    KAUST Repository

    Wang, Jim Jing-Yan

    2014-09-07

    In this paper, a novel pattern classification approach is proposed by regularizing the classifier learning to maximize mutual information between the classification response and the true class label. We argue that, with the learned classifier, the uncertainty of the true class label of a data sample should be reduced by knowing its classification response as much as possible. The reduced uncertainty is measured by the mutual information between the classification response and the true class label. To this end, when learning a linear classifier, we propose to maximize the mutual information between classification responses and true class labels of training samples, besides minimizing the classification error and reducing the classifier complexity. An objective function is constructed by modeling mutual information with entropy estimation, and it is optimized by a gradient descend method in an iterative algorithm. Experiments on two real world pattern classification problems show the significant improvements achieved by maximum mutual information regularization.

  3. Channel box

    Tanabe, Akira.

    1993-01-01

    In a channel box of a BWR type reactor, protruding pads are disposed in axial position on the lateral side of a channel box opposing to a control rod and facing the outer side portion of the control rod in a reactor core loaded state. In the initial loading stage of fuel assemblies, channel fasteners and spacer pads are abutted against each other in the upper portion between the channel boxes sandwiching the control rod therebetween. Further, in the lower portion, a gap as a channel for the movement of the control rod is ensured by the support of fuel support metals. If the channel box is bent toward the control rod along with reactor operation, the pads are abutted against each other to always ensure the gap through which the control rod can move easily. Further, when the pads are brought into contact with each other, the bending deformation of the channel box is corrected by urging to each other. Thus, the control rod can always be moved smoothly to attain reactor safety operation. (N.H.)

    We analyze models of discretized string theories, where the path integral over world sheet variables is regularized by summing over triangulated surfaces. The inclusion of curvature in the action is a necessity for the scaling of the string tension. We discuss the physical properties of models with extrinsic curvature terms in the action and show that the string tension vanishes at the critical point where the bare extrinsic curvature coupling tends to infinity. Similar results are derived for models with intrinsic curvature. (orig.)

    Immigration is a fairly recent phenomenon in Spain and there are still few scientific publications on tuberculosis (TB) and immigration. Therefore, the aim of this study is to describe the differential characteristics of TB in the immigrant population with respect to natives in Spain. Literature review of original articles written in Spanish or English and published 1998-2012 about TB among immigrant population. The articles with the key words "Tuberculosis", "immigrants" and "Spain" were included. Literature search was performed in Medline and MEDES. A total of 72,087 articles on TB were detected worldwide, 6% of them dealt with the immigration issue. Regarding Spain we found 2,917 articles representing 4% of the papers published worldwide, and in 219 (7.5%) immigration was considered. Of the 219 articles, 48% were published in Spanish journals and the 52% remaining in Anglo-Saxon journals. 93.5% of immigrants with TB were younger than 51, whereas this percentage was 64.9% in natives. Drug resistance can be seen in 7.8% of the immigrant population but in only 3.8% of natives. It was also detected that the unavailability of a health card could be a problem. Immigrants with TB were characterized by being younger and having more drug resistance and coming mostly from Latin America, Eastern Europe, Africa and Asia. It was also detected that the unavailability of a health card could be a problem.

  7. To what extent does immigration affect inequality?

    Berman, Yonatan; Aste, Tomaso

    2016-11-01

    The current surge in income and wealth inequality in most western countries, along with the continuous immigration to those countries demand a quantitative analysis of the effect immigration has on economic inequality. This paper presents a quantitative analysis framework providing a way to calculate this effect. It shows that in most cases, the effect of immigration on wealth and income inequality is limited, mainly due to the relative small scale of immigration waves. For a large scale flow of immigrants, such as the immigration to the US, the UK and Australia in the past few decades, we estimate that 10 % ÷ 15 % of the wealth and income inequality increase can be attributed to immigration. The results demonstrate that immigration could possibly decrease inequality substantially, if the characteristics of the immigrants resemble the characteristics of the destination middle class population in terms of wealth or income. We empirically found that the simple linear relation ΔS = 0.18 ρ roughly describes the increase in the wealth share of the top 10 % due to immigration of a fraction ρ of the population.

    Inadequate functional health literacy is a common problem in immigrant populations. The aim of this study was to investigate the association between oral (dental) health literacy (OHL) and participation in oral health care among Brazilian immigrants in Toronto, Ontario, Canada. The study used a cross-sectional design and a convenience sample of 101 Brazilian immigrants selected through the snowball sampling technique. Data were analyzed using descriptive statistics and logistic regression modeling. Most of the sample had adequate OHL (83.1 %). Inadequate/marginal OHL was associated with not visiting a dentist in the preceding year (OR = 3.61; p = 0.04), not having a dentist as the primary source of dental information (OR = 5.55; p < 0.01), and not participating in shared dental treatment decision making (OR = 1.06; p = 0.05; OHL as a continuous variable) in multivariate logistic regressions controlling for covariates. A low average annual family income was associated with two indicators of poor participation in oral health care (i.e., not having visited a dentist in the previous year, and not having a dentist as regular source of dental information). Limited OHL was linked to lower participation in the oral health care system and with barriers to using dental services among a sample of Brazilian immigrants. More effective knowledge transfer will be required to help specific groups of immigrants to better navigate the Canadian dental care system.

    There is experimental evidence that swift light ions incident at small angles towards single crystalline surfaces can lose an appreciable fraction of their kinetic energy during reflection. It is shown that these projectiles penetrate into the bulk surface region of the crystal. They can travel as channeled particles along long paths through the solid (surface channeling). The angular distribution and the depth history of the re-emerged projectiles are investigated by computer simulations. A considerable fraction of the penetrating projectiles re-emerges from the crystal with constant transverse energy if the angle of incidence is smaller than the critical angle for axial channeling. Analytical formulae are derived based on a diffusion model for surface channeling. A comparison with experimental data exhibits the relevance of the analytical solutions. (Auth.)

    Objective To examine the use of hormonal contraceptives among immigrant and native women in Norway. Design Nationwide registry-based study based on merged data from the Norwegian Prescription Database, the Norwegian Population Registry, the Regular General Practitioner Database and the Medical Birth Registry. Setting Norway. Sample All women born abroad to two foreign-born parents (immigrants), or born in Norway to two Norwegian-born parents (natives) aged 16–45 years, who lived in Norway in 2008. Methods Data on all collected supplies of hormonal contraceptives in 2008 were merged with demographic, socio-economic and immigration data, information on any delivery and women's general practitioners. Main outcome measures User rates of hormonal contraception and predictors of contraceptive use. Results A total of 893 073 women were included, of whom 130 080 were immigrants. More native women (38%) used hormonal contraceptives compared with all immigrant groups (15–24%). The odds ratios for any use of hormonal contraceptives for immigrants compared with Norwegian-born women were; Nordic countries 0.53, South and Central America 0.53, Western countries 0.39, Asia 0.30, Eastern Europe 0.29, Africa 0.29. Work, education, long stay in Norway and young age of immigration predicted the use of hormonal contraceptives among immigrants. Conclusions The use of hormonal contraceptives varies between natives and immigrant groups. Further work is needed to ascertain whether these differences can be explained by higher desires for fertility, preferential use of non-hormonal contraceptives or other reasons identified through qualitative research.

    Rates of mammography screening for breast cancer are disproportionately low in certain subgroups including low-income and immigrant women. The purpose of the study was to examine differences in rates of appropriate breast cancer screening (i.e., screening mammography every 2 years) among Ontario immigrant women by world region of origin and explore the association between appropriate breast cancer screening among these women groups and individual and structural factors. A cohort of 183,332 screening-eligible immigrant women living in Ontario between 2010 and 2012 was created from linked databases and classified into eight world regions of origin. Appropriate screening rates were calculated for each region by age group and selected sociodemographic, immigration, and healthcare-related characteristics. The association between appropriate screening across the eight regions of origin and selected sociodemographic, immigration, and health-related characteristics was explored using multivariate Poisson regression. Screening varied by region of origin, with South Asian women (48.5%) having the lowest and Caribbean and Latin American women (63.7%) the highest cancer screening rates. Factors significantly associated with lower screening across the world regions of origin included living in the lowest income neighborhoods, having a refugee status, being a new immigrant, not having a regular physical examination, not being enrolled in a primary care patient enrollment model, having a male physician, and having an internationally trained physician. Multiple interventions entailing cross-sector collaboration, promotion of patient enrollment models, community engagement, comprehensive and intensive outreach to women, and knowledge translation and transfer to physicians should be considered to address screening disparities among immigrant population. Consideration should be given to design and delivery of culturally appropriate and easily accessible cancer screening programs

    A brief summary is given of the principal methods used for initiating spark channels and the various highly time-resolved techniques developed recently for studies with nanosecond resolution. The importance of the percentage overvoltage in determining the early history and subsequent development of the various phases of the growth of the spark channel is discussed. An account is then given of the recent photographic, oscillographic and spectroscopic investigations of spark channels initiated by co-axial cable discharges of spark gaps at low [{approx} 1%] overvoltages. The phenomena observed in the development of the immediate post-breakdown phase, the diffuse glow structure, the growth of the luminous filament and the final formation of the spark channel in hydrogen are described. A brief account is also given of the salient features emerging from corresponding studies of highly overvolted spark gaps in which the spark channel develops from single avalanche conditions. The essential differences between the two types of channel formation are summarized and possible explanations of the general features are indicated. (author)

When immigration is raised as a normative issue two questions become salient, one about what the right to exclude is, and one about whether and how it might be justified. This paper considers...... the first question. The paper starts by noting that standard debates about immigration have not addressed what the right to exclude is. Standard debates about immigration furthermore tend to result either in fairly strong cases for open borders or in denials that considerations of justice apply...... to immigration at all, which results in state discretion positions. This state of debate is both theoretically unsatisfactory and normatively implausible. The paper therefore explores an alternative approach to the right to exclude immigrants from the perspective of recent debates about the territorial rights...

  16. [Synopsis about the hypothesis of "information channel" of channel-collateral system].

    Science.gov (United States)

    Chang, Xi-Lang

    2008-10-01

    The author of the present paper founded a theorem about the "incompleteness of single channel structure" (nerve, blood vessel, lymphatic, interspace, aperture, etc.) through quantitative and qualitative analysis about the economic information channel in the human body, which eliminates the probability of single channel structure in the information channel of channel (meridian)-collateral system. After comprehensive analysis on the current researches, the author puts forward a neodoxy, i.e., the body "information channel" structure of the channel-collateral system, mainly follows the distribution regularity of systemic statistics, and is not a single specific entity; various layers of the information channel in the main stems of the channel-collaterals are composed of optimized structure tissues. Hence, the structure of this information channel of channel-collateral system is an overall-optimized, sequential and compatible systemic structure. From this neodoxy, the author brings forward a working principle of channel-collaterals, which is supported theoretically by bio-auxology. The longitudinal distribution of the main stems of meridian-collaterals is considered to result from that in the process of the animal evolution, in the animals moving forward, the microscopic complicated movement of intracorporeal information and energy molecules is related to the forward macroscopic and non-uniform movement of organism in trans-measure. Its impulse and kinetic momentum forms a main vector in the longitudinal direction of the body (the direction of the main stem of channel-collaterals). In order to adapt to and utilize natural regularities, the main stems of the channel-collaterals gradually differentiate and evolve in the living organism, forming a whole system. The "hypothesis of biological origin of channel-collateral system" and "that of information channel of the channel-collaterals in the body" constitute a relatively complete theoretical system framework.

    2015-03-01

    Seniors comprise a growing proportion of new U.S. immigrants. We investigate whether late-age immigrants are disadvantaged in older age relative to those arriving earlier in life, based on income, reliance on public benefits, and access to public medical insurance. We test whether the 1996 welfare reform law altered the relationships between age at immigration and these outcomes. Immigrants aged 65 and older in the 1994-2010 Current Population Surveys were classified by age at immigration. Median and logistic regressions are used to estimate the association between age at immigration and several outcomes and to test whether these associations differ for arrivals before and after welfare reform. Late-age immigration is strongly associated with lower personal income, lower rates of Medicare and Social Security receipt, and higher participation in Supplemental Security Income (SSI) and Medicaid. Arrival after 1996 is associated with lower rates of SSI, Medicaid, and Medicare receipt. The association between late-age immigration and income is stronger for post-1996 arrivals relative to earlier arrivals, whereas that between late-age immigration and Medicaid is weaker, suggesting that the penalty conferred by late-age immigration grew after reform. Late-age immigrants face formidable economic disadvantages exacerbated by exclusion from public benefits, with implications for immigration, health care, and welfare policy. © The Author 2014.

    Regularization methods aimed at finding stable approximate solutions are a necessary tool to tackle inverse and ill-posed problems. Usually the mathematical model of an inverse problem consists of an operator equation of the first kind and often the associated forward operator acts between Hilbert spaces. However, for numerous problems the reasons for using a Hilbert space setting seem to be based rather on conventions than on an approprimate and realistic model choice, so often a Banach space setting would be closer to reality. Furthermore, sparsity constraints using general Lp-norms or the B

    Immigrants from certain low- and middle-income countries are more prone to cancers attributed to viral infections in early life. Cervical cancer is caused by human papillomavirus but is highly preventable by regular screening. We assessed participation among immigrants in a population-based cervical screening programme and identified factors that predicted non-adherence within different immigrant groups. We used data from several nationwide registries. The study population consisted of 208 626 (15%) immigrants and 1 157 223 (85%) native Norwegians. Non-adherence was defined as no eligible screening test in 2008-12. We estimated prevalence ratios with 95% confidence intervals (CIs) for factors associated with non-adherence by modified Poisson regression. In total, 52% of immigrants were not screened. All immigrants showed 1.72 times higher non-adherence rates (95% CI 1.71-1.73) compared with native Norwegian women when adjusted for age and parity. The proportion of non-adherent immigrants varied substantially by region of origin and country of origin. Being unemployed or not in the workforce, being unmarried, having low income and having a male general practitioner was associated with non-adherence regardless of region of origin. Living immigrant groups. An increasing proportion of immigrants and low screening participation among them pose new public health challenges in Europe. Immigrants are diverse in terms of their sociodemographic attributes and screening participation. Tailored information and service delivery may be necessary to increase cancer screening among immigrants. © The Author 2017.

    Immigration poses numerous challenges for health professionals and public health lawyers. This article reviews these challenges. We begin by offering some background on immigration and health and then explain some of the reasons why immigrants are less likely than natives to have health insurance. Next we turn to a discussion of some of the particular challenges relating to the health care of refugees. We conclude by analyzing and rejecting some of the arguments that are made for discriminating against immigrants with respect to the provision of public health benefits and services.

    We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage...... formation at the most disaggregate level – the workplace. Using linked employer-employee data, we find that an increased use of low-skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant...

Using a sample of students, we examined the validity of different types of indicators used to measure the frequency of media consumption, the recall of news regarding immigration and the degree of media credibility in order to explain racist and xenophobic attitudes. Results reveal a clear association between the news media and native group attitudes towards immigration, thus demonstrating the usefulness of these indicators.

  16. Environmental and occupational exposures in immigrant health.

    Eamranond, Pracha P; Hu, Howard

    2008-09-23

    Immigrants comprise vulnerable populations that are frequently exposed to a multitude of environmental and occupational hazards. The historical context behind state and federal legislation has helped to foster an environment that is particularly hostile toward caring for immigrant health. Current hazards include toxic exposures, air and noise pollution, motor vehicle accidents, crowded living and work environments with inadequate ventilation, poor sanitation, mechanical injury, among many others. Immigrants lack the appropriate training, materials, health care access, and other resources to reduce their exposure to preventable environmental and occupational health risks. This dilemma is exacerbated by current anti-immigrant sentiments, miscommunication between native and immigrant populations, and legislation denying immigrants access to publicly funded medical care. Given that current health policy has failed to address immigrant health appropriately and political impetus is lacking, efforts should also focus on alternative solutions, including organized labor. Labor unions that serve to educate workers, survey work environments, and defend worker rights will greatly alleviate and prevent the burden of disease incurred by immigrants. The nation's health will benefit from improved regulation of living and workplace environments to improve the health of immigrants, regardless of legal status.

    Little research has focused on the relation of immigration and suicidal behaviour in youth. Nevertheless, the impact of migration on the mental health of youth is an issue of increasing societal importance. This review aimed to present studies on the prevalence of suicidal behaviour in immigrant youth in various countries and to provide possible explanations for suicidal behaviour in immigrant youth, especially regarding acculturation. The review included a literature search to locate articles on the subject of suicidal behaviour in immigrant youth in the context of acculturation. Studies on suicidal behaviour in culturally diverse youth are few and most of the existing research does not differentiate ethnic minorities from immigrants. Studies on epidemiology and on specific risk factors were found regarding various immigrant youth including Hispanics in the United States, Asians in North America and Europe, as well as comparative studies between different immigrant groups in specific countries. The relation between immigration status and suicidal behaviours in youth appears to vary by ethnicity and country of settlement. Time spent in the new country as well as intergenerational communication and conflicts with parents have, in many of the studies, been related to suicidality in immigrant youth. Summing up, there is a clear and urgent need to further pursue the work in this field, to develop targeted public health interventions as well as psychosocial treatment for preventing suicide in these youth.

    Mokhtari, Aryan; Ribeiro, Alejandro

    2014-12-01

    RES, a regularized stochastic version of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method is proposed to solve convex optimization problems with stochastic objectives. The use of stochastic gradient descent algorithms is widespread, but the number of iterations required to approximate optimal arguments can be prohibitive in high dimensional problems. Application of second order methods, on the other hand, is impracticable because computation of objective function Hessian inverses incurs excessive computational cost. BFGS modifies gradient descent by introducing a Hessian approximation matrix computed from finite gradient differences. RES utilizes stochastic gradients in lieu of deterministic gradients for both, the determination of descent directions and the approximation of the objective function's curvature. Since stochastic gradients can be computed at manageable computational cost RES is realizable and retains the convergence rate advantages of its deterministic counterparts. Convergence results show that lower and upper bounds on the Hessian egeinvalues of the sample functions are sufficient to guarantee convergence to optimal arguments. Numerical experiments showcase reductions in convergence time relative to stochastic gradient descent algorithms and non-regularized stochastic versions of BFGS. An application of RES to the implementation of support vector machines is developed.

  6. Regularized Label Relaxation Linear Regression.

    2018-04-01

    Linear regression (LR) and some of its variants have been widely used for classification problems. Most of these methods assume that during the learning phase, the training samples can be exactly transformed into a strict binary label matrix, which has too little freedom to fit the labels adequately. To address this problem, in this paper, we propose a novel regularized label relaxation LR method, which has the following notable characteristics. First, the proposed method relaxes the strict binary label matrix into a slack variable matrix by introducing a nonnegative label relaxation matrix into LR, which provides more freedom to fit the labels and simultaneously enlarges the margins between different classes as much as possible. Second, the proposed method constructs the class compactness graph based on manifold learning and uses it as the regularization item to avoid the problem of overfitting. The class compactness graph is used to ensure that the samples sharing the same labels can be kept close after they are transformed. Two different algorithms, which are, respectively, based on -norm and -norm loss functions are devised. These two algorithms have compact closed-form solutions in each iteration so that they are easily implemented. Extensive experiments show that these two algorithms outperform the state-of-the-art algorithms in terms of the classification accuracy and running time.

    Americans' conflicted attitudes toward immigrants and immigration has stymied immigration reform for decades. In this article, we explore the nuanced nature of stereotypes about immigrants and how they relate to ambivalent attitudes toward immigrant groups and the disparate array of immigration policies that affect them. Using item response theory and multiple regression analysis, we identified and related stereotypes of different immigrant groups to group-based and policy attitudes. Results demonstrate that ambivalent stereotypes mapped onto ambivalent group-based and immigration policy attitudes. Specifically, stereotypes that portray groups in positive or sympathetic ways predicted positive attitudes toward the group and more supportive attitudes toward policies that facilitate their immigration to the United States. Conversely, negative qualities predicted negative attitudes toward the same group and support for policies that prevent the group from immigrating. Results are discussed in light of current theory related to stereotype content, complementarity of stereotypes, and broader implications for immigration attitudes and policy.

    Full Text Available This study focuses on stakeholders’ participation, perceptions and local contextualization in the Informal Settlement (IS regularization processes in Khulna City. These processes are undertaken to address livelihood challenges of IS dwellers and to operationalize development initiatives in informal regularization projects. Adopting both a qualitative and quantitative approach, the research results show that IS formation in Khulna City started slowly with rural immigration. These immigrants remain vulnerable to climate change although some initiatives were undertaken since the last 20 years to improve their living conditions. The IS dwellers and local leaders initially participated in these settlement-upgrading initiatives due to accompanied incentives but they became adamant after the project period ended. It was also found that the city local government and NGOs do not have any permanent arrangement to sustain the IS regularization processes. The analysis of the interrelationships among the stakeholders revealed that the relevant public agencies are in conflict, and the role of the private sector is less recognized. The initiatives undertaken so far have limited success especially in granting tenure security, and the private landowners or local authorities that trespassed public spaces resort to forceful eviction. Amidst all these, there is the need for the formulation and implementation of climate resilience policies that address stakeholder participations in mitigating climate change consequences and enhance livelihood development.

    Full Text Available Abstract Background Statistics on occupational accidents are based on data from registered employees. With the increasing number of immigrants employed illegally and/or without regular working visas in many developed countries, it is of interest to estimate the injury rate among such unregistered workers. Findings The current study was conducted in an area of North-Eastern Italy. The sources of information employed in the present study were the Accidents and Emergencies records of a hospital; the population data on foreign-born residents in the hospital catchment area (Health Care District 4, Primary Care Trust 20, Province of Verona, Veneto Region, North-Eastern Italy; and the estimated proportion of illegally employed workers in representative samples from the Province of Verona and the Veneto Region. Of the 419 A&E records collected between January and December 2004 among non European Union (non-EU immigrants, 146 aroused suspicion by reporting the home, rather than the workplace, as the site of the accident. These cases were the numerator of the rate. The number of illegally employed non-EU workers, denominator of the rate, was estimated according to different assumptions and ranged from between 537 to 1,338 individuals. The corresponding rates varied from 109.1 to 271.8 per 1,000 non-EU illegal employees, against 65 per 1,000 reported in Italy in 2004. Conclusions The results of this study suggest that there is an unrecorded burden of illegally employed immigrants suffering from work related injuries. Additional efforts for prevention of injuries in the workplace are required to decrease this number. It can be concluded that the Italian National Institute for the Insurance of Work Related Injuries (INAIL probably underestimates the incidence of these accidents in Italy.

    2011-01-01

    The children from immigrant families in the United States make up a historically diverse population, and they are demonstrating just as much diversity in their experiences in the K-12 educational system. Robert Crosnoe and Ruth López Turley summarize these K-12 patterns, paying special attention to differences in academic functioning across segments of the immigrant population defined by generational status, race and ethnicity, and national origin. A good deal of evidence points to an immigrant advantage in multiple indicators of academic progress, meaning that many youths from immigrant families outperform their peers in school. This apparent advantage is often referred to as the immigrant paradox, in that it occurs despite higher-than-average rates of social and economic disadvantages in this population as a whole. The immigrant paradox, however, is more pronounced among the children of Asian and African immigrants than other groups, and it is stronger for boys than for girls. Furthermore, evidence for the paradox is far more consistent in secondary school than in elementary school. Indeed, school readiness appears to be one area of potential risk for children from immigrant families, especially those of Mexican origin. For many groups, including those from Latin America, any evidence of the immigrant paradox usually emerges after researchers control for family socioeconomic circumstances and youths' English language skills. For others, including those from Asian countries, it is at least partially explained by the tendency for more socioeconomically advantaged residents of those regions to leave their home country for the United States. Bilingualism and strong family ties help to explain immigrant advantages in schooling; school, community, and other contextual disadvantages may suppress these advantages or lead to immigrant risks. Crosnoe and Turley also discuss several policy efforts targeting young people from immigrant families, especially those of Latin

    2013-01-01

    The standard account of American immigration focuses on the acculturation and assimilation of immigrants and their children to American society. This analysis typically ignores the significant contributions of immigrants to the creation of American culture through the performing arts, sciences, and other cultural pursuits. Immigrants and their children are not born with more creative talents than native-born citizens, but their selectivity and marginality may have pushed and pulled those with ability into high-risk career paths that reward creative work. The presence of large numbers of talented immigrants in Hollywood, academia, and the high-tech industries has pushed American institutions to be more meritocratic and open to innovation than they would be otherwise.

  18. Immigration as a social determinant of health.

    Although immigration and immigrant populations have become increasingly important foci in public health research and practice, a social determinants of health approach has seldom been applied in this area. Global patterns of morbidity and mortality follow inequities rooted in societal, political, and economic conditions produced and reproduced by social structures, policies, and institutions. The lack of dialogue between these two profoundly related phenomena-social determinants of health and immigration-has resulted in missed opportunities for public health research, practice, and policy work. In this article, we discuss primary frameworks used in recent public health literature on the health of immigrant populations, note gaps in this literature, and argue for a broader examination of immigration as both socially determined and a social determinant of health. We discuss priorities for future research and policy to understand more fully and respond appropriately to the health of the populations affected by this global phenomenon.

Recent studies have suggested poorer health outcomes for immigrants living in countries with poorly...... confounders and data comparability issues (e.g., French cross-sectional data) may affect the findings, this study suggests that different macro-level policy contexts may influence immigrants' mortality.

  1. Class of regular bouncing cosmologies

    Science.gov (United States)

    Vasilić, Milovan

    2017-06-01

    In this paper, I construct a class of everywhere regular geometric sigma models that possess bouncing solutions. Precisely, I show that every bouncing metric can be made a solution of such a model. My previous attempt to do so by employing one scalar field has failed due to the appearance of harmful singularities near the bounce. In this work, I use four scalar fields to construct a class of geometric sigma models which are free of singularities. The models within the class are parametrized by their background geometries. I prove that, whatever background is chosen, the dynamics of its small perturbations is classically stable on the whole time axis. Contrary to what one expects from the structure of the initial Lagrangian, the physics of background fluctuations is found to carry two tensor, two vector, and two scalar degrees of freedom. The graviton mass, which naturally appears in these models, is shown to be several orders of magnitude smaller than its experimental bound. I provide three simple examples to demonstrate how this is done in practice. In particular, I show that graviton mass can be made arbitrarily small.

    Directory of Open Access Journals (Sweden)

    Airaksinen M.

    2006-12-01

    Full Text Available European integration has facilitated the emigration inside Europe and it has been predicted that the amount of immigrants in Southern European countries will increase in the future. As these people age and their morbidity increases, they will demand more services from local health care than immigrants do at the moment. The aim of this study is to determine the amount of Finnish people who have moved to Spain for health reasons (health immigrants and whether their health service and analgesic usage patterns differed from those of non-health immigrants. Methods: This study was carried out among Finnish people living in Costa del Sol area, southern Spain. The data were collected by questionnaire during 2002 by using a convenience sample of 1,000 Finns living permanently in the area (response rate 53%, n=530. Statistical analyses were conducted using statistical software SPSS 11.5.Results: Two-thirds of the respondents were categorised as health immigrants. Health immigrants were more often suffering from chronic morbidity, their perceived health status was poorer and they used public health services more often than the non-health immigrants. Half (50% of the all respondents had used some analgesics during the two weeks before the survey. There were more analgesic users among the health immigrant group (54 % vs. 43 %, p = 0.034 and they also used analgesics more frequently than the non-health immigrants (27 % vs. 9 %, p= 0.020. Conclusions: Our study indicates, that high amount of Finnish immigrants suffer from some degree of health problems and the health state factors have a large influence on the emigration into Spain. As this kind of trend might also exist among immigrants from other EU-nations, immigrants might burden the local Spanish health care services in the future. Therefore the Providers of health care services in immigrant areas should consider these trends in planning health care in the future.

  18. Poverty and program participation among immigrant children.

    Science.gov (United States)

    Borjas, George J

    2011-01-01

    Researchers have long known that poverty in childhood is linked with a range of negative adult socioeconomic outcomes, from lower educational achievement and behavioral problems to lower earnings in the labor market. But few researchers have explored whether exposure to a disadvantaged background affects immigrant children and native children differently. George Borjas uses Current Population Survey (CPS) data on two specific indicators of poverty-the poverty rate and the rate of participation in public assistance programs-to begin answering that question. He finds that immigrant children have significantly higher rates both of poverty and of program participation than do native children. Nearly half of immigrant children are being raised in households that receive some type of public assistance, compared with roughly one-third of native children. Although the shares of immigrant and native children living in poverty are lower, the rate for immigrant children is nonetheless about 15 percentage points higher than that for native children-about the same as the gap in public assistance. Poverty and program participation rates among different groups of immigrant children also vary widely, depending in part on place of birth (foreign- or U.S.-born), parents (immigrant or native), and national origin. According to the CPS data, these native-immigrant differences persist into young adulthood. In particular, the program participation and poverty status of immigrant children is strongly correlated with their program participation and poverty status when they become young adults. But it is not possible, says Borjas, to tell whether the link results from a set of permanent factors associated with specific individuals or groups that tends to lead to "good" or "bad" outcomes systematically over time or from exposure during childhood to adverse socioeconomic outcomes, such as poverty or welfare dependency. Future research must explore the causal impact of childhood poverty on

    "This paper develops a simple two-country model of illegal immigration in an attempt to examine the interaction among variables such as the stock of migrant labor, the unemployment rates of the two economies, and the rate of spending by the host country on the enforcement of its immigration restrictions. The focus of the analysis is on the dynamics of immigration policy and on its role in determining the nature of the mechanism by which disturbances to the labor market of one country are transmitted to that of the other in the short run and in the long run." excerpt

  1. The Healthy Immigrant Effect and Immigrant Selection: Evidence from Four Countries

    2006-01-01

    The existence of a healthy immigrant effect – where immigrants are on average healthier than the native-born – is now a well accepted phenomenon. There are many competing explanations for this phenomenon including health screening by recipient countries, healthy behaviour prior to migration followed by the steady adoption of new country (less) healthy behaviours, and immigrant self-selection where healthier and wealthier people tend to be migrants. We explore the last two of these explanation...

    A higher derivative regularization which automatically leads to the consistent chiral anomaly is analyzed in detail. It explicitly breaks all the local gauge symmetry but preserves global chiral symmetry and leads to the chirally symmetric consistent anomaly. This regularization thus clarifies the physics content contained in the consistent anomaly. We also briefly comment on the application of this higher derivative regularization to massless QED.

    Full Text Available Background: Regularity effect can affect performance in prospective memory (PM, but little is known on the cognitive processes linked to this effect. Moreover, its impacts with regard to aging remain unknown. To our knowledge, this study is the first to examine regularity effect in PM in a lifespan perspective, with a sample of young, intermediate, and older adults. Objective and design: Our study examined the regularity effect in PM in three groups of participants: 28 young adults (18–30, 16 intermediate adults (40–55, and 25 older adults (65–80. The task, adapted from the Virtual Week, was designed to manipulate the regularity of the various activities of daily life that were to be recalled (regular repeated activities vs. irregular non-repeated activities. We examine the role of several cognitive functions including certain dimensions of executive functions (planning, inhibition, shifting, and binding, short-term memory, and retrospective episodic memory to identify those involved in PM, according to regularity and age. Results: A mixed-design ANOVA showed a main effect of task regularity and an interaction between age and regularity: an age-related difference in PM performances was found for irregular activities (older < young, but not for regular activities. All participants recalled more regular activities than irregular ones with no age effect. It appeared that recalling of regular activities only involved planning for both intermediate and older adults, while recalling of irregular ones were linked to planning, inhibition, short-term memory, binding, and retrospective episodic memory. Conclusion: Taken together, our data suggest that planning capacities seem to play a major role in remembering to perform intended actions with advancing age. Furthermore, the age-PM-paradox may be attenuated when the experimental design is adapted by implementing a familiar context through the use of activities of daily living. The clinical

  7. Regularization and error assignment to unfolded distributions

    CERN Document Server

    2011-01-01

    The commonly used approach to present unfolded data only in graphical formwith the diagonal error depending on the regularization strength is unsatisfac-tory. It does not permit the adjustment of parameters of theories, the exclusionof theories that are admitted by the observed data and does not allow the com-bination of data from different experiments. We propose fixing the regulariza-tion strength by a p-value criterion, indicating the experimental uncertaintiesindependent of the regularization and publishing the unfolded data in additionwithout regularization. These considerations are illustrated with three differentunfolding and smoothing approaches applied to a toy example.

  10. On the theory of drainage area for regular and non-regular points

    Science.gov (United States)

    Bonetti, S.; Bragg, A. D.; Porporato, A.

    2018-03-01

    The drainage area is an important, non-local property of a landscape, which controls surface and subsurface hydrological fluxes. Its role in numerous ecohydrological and geomorphological applications has given rise to several numerical methods for its computation. However, its theoretical analysis has lagged behind. Only recently, an analytical definition for the specific catchment area was proposed (Gallant & Hutchinson. 2011 Water Resour. Res. 47, W05535. (doi:10.1029/2009WR008540)), with the derivation of a differential equation whose validity is limited to regular points of the watershed. Here, we show that such a differential equation can be derived from a continuity equation (Chen et al. 2014 Geomorphology 219, 68-86. (doi:10.1016/j.geomorph.2014.04.037)) and extend the theory to critical and singular points both by applying Gauss's theorem and by means of a dynamical systems approach to define basins of attraction of local surface minima. Simple analytical examples as well as applications to more complex topographic surfaces are examined. The theoretical description of topographic features and properties, such as the drainage area, channel lines and watershed divides, can be broadly adopted to develop and test the numerical algorithms currently used in digital terrain analysis for the computation of the drainage area, as well as for the theoretical analysis of landscape evolution and stability.

    2015-08-01

    Full Text Available Successful implementation of any broad-scale immigrant legalization program requires an adequately funded infrastructure of immigrant-serving organizations. In 2014, President Obama announced an expanded Deferred Action for Childhood Arrivals (DACA program, as well as the Deferred Action for Parents of Citizens and Lawful Permanent Residents (DAPA program, which would make it possible for approximately five million people to attain lawful, albeit temporary, status and employment authorization. As the initial DACA program instituted in 2012 has already stretched the capacity of immigrant-serving organizations to their limits or even beyond them, the possibility of full implementation of DAPA and the expanded DACA programs presents a formidable challenge for these organizations.In this paper, the Human Resources Working Group of the Committee for Immigration Reform Implementation (CIRI draws on the lessons of the Immigrant Reform and Control Act of 1986 (IRCA, DACA, and other initiatives to provide a roadmap for immigrant service delivery agencies and their partners in planning for implementation of the expanded DACA and the DAPA programs, with an eye (ultimately to broad legislative reform. In particular, this paper focuses on the funding and human resources that the immigrant service delivery field, writ large, would require to implement these programs.If expanded DACA and DAPA were implemented, the CIRI Working Group estimates that, of the total of five million that may be eligible, 1.08 million individuals will require extensive application assistance, generating the need for approximately three times more full-time staff than are currently in the field. Moreover, without additional funding and staff, agencies will likely not be able to shift a portion of staff time to accommodate any new program, even taking the typical fee-for-service model into account. Thus, the paper identifies a pressing need for “upfront” funding as early in the

    Chinese immigrants in Canada have a disproportionately high risk for hepatitis B compared with non-Hispanic Whites. Hepatitis B is the leading cause of hepatocellular carcinoma among Asian immigrants to North America. English-as-a-second-language (ESL) classes are an effective way of reaching newly immigrated individuals and are a potential channel for delivering health messages. Using data from 6 focus groups among ESL instructors and students, we characterized perceptions about activities that are successfully used in ESL classrooms and strategies for delivering hepatitis B information. RESULTS. Instructors and students generally reported that activities that focused on speaking and listening skills and that addressed content relevant to students' daily lives were successful in the classroom. Instructors generally avoided material that was irrelevant or too difficult to understand. Focus group participants offered strategies for delivering hepatitis B information in ESL classrooms; these strategies included addressing symptoms and prevention and not singling out a specific population subgroup to avoid stigmatization. These findings might assist efforts to develop ESL curricula that target immigrant populations.

    Migration is a growing phenomenon in Latin America influenced by several factors such as economic stability, employment, social welfare, education and health system. Currently Chile has a positive migration flow rate. Particularly, a significant number of Haitian immigrants has been observed du ring the last years, especially after earthquake of 2010. These immigrants present a different cultural background expressed in relevant aspects of living including parenting and healthcare. Knowing the Haitian culture and its health situation is relevant for a better understanding of their health needs. Haitian people come to Chile looking for a cordial reception and willing to find a place with better perspectives of wellbeing in every sense. Immigration represents a major challenge for Chilean health system that must be embraced. Integration efforts in jobs, health, education system and community living should be enhanced to ensure a prosper settlement in our country. A new immigration law is crucial to solving major problems derived from current law created in 1975.

To determine the prevalence of Common Mental Disorders (CMD) among immigrants who live in Independencia, a quarter in Santiago, Chile. A cross sectional study was carried out in the primary health care clinic and in the state-funded school of Independencia. A representative sample of 282 adults and 341 children were interviewed. Mental disorders were diagnosed using CIS-R and MINI structured interviews. The interviewed immigrants came mostly from Peru. The prevalence of mental disorders in the adult population was 17.8% and among children, it was 29.3%. The adult immigrants have a lower prevalence of mental disorders than the Chilean population but it increases among children. Barriers of access to health services, that should be solved, were detected.

    This study examines predictors of transnational dental care utilization, or the use of dental care across national borders, over a 4-year period among immigrants to Canada. Data from the Longitudinal Survey of Immigrants to Canada (LSIC, 2001-2005) were used. Sampling and bootstrap weights were applied to make the data nationally representative. Bivariate and multiple logistic regression analyses were applied to identify factors associated with immigrants' transnational dental care utilization. Approximately 13% of immigrants received dental care outside Canada over a period of 4 years. Immigrants lacking dental insurance (OR = 2.05; 95% CI: 1.55-2.70), those reporting dental problems (OR = 1.45; 95% CI: 1.12-1.88), who were female (OR = 1.59; 95% CI: 1.22-2.08), aged ≥ 50 years (OR = 2.30; 95% CI: 1.45-3.64), and who were always unemployed (OR = 1.70; 95% CI: 1.20-2.39) were more likely to report transnational dental care utilization. History of social assistance was inversely correlated with the use of dental services outside Canada (OR = 0.48; 95% CI: 0.30-0.83). It is estimated that roughly 11 500 immigrants have used dental care outside Canada over a 4-year period. Although transnational dental care utilization may serve as an individual solution for immigrants' initial barriers to accessing dental care, it demonstrates weaknesses to in-country efforts at providing publicly funded dental care to socially marginalized groups. Policy reforms should be enacted to expand dental care coverage among adult immigrants. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  7. Intermarriage among New Immigrants in the USA.

    Bohra-Mishra, Pratikshya; Massey, Douglas S

    The study uses the New Immigrant Survey data collected in 2003 to fill a void in the existing literature on the regional variations in exogamy among the new first generation immigrants in the United States. It further improves on some methodological issues in existing studies. Our empirical results show that immigrants from different regions of origin indeed vary significantly in their choice of spouse, even after controlling for other important predictors of exogamy. Latino females are the most exogamous of all groups while Latino males as well are more exogamous than their Asian male counterparts and do not differ much from male immigrants from Europe, Central Asia and the residual "other" category. The results are somewhat counterintuitive given the history of European immigration to the US, and the higher level of structural assimilation attained by Asians in the US compared to Latinos. The contradictory results therefore, point towards a rapid assimilation of Latin Americans into the US society. On the other hand, first generation Asians demonstrated the lowest level of all types of exogamy in general, except Asian women were not the most endogamous compared to Europeans, Central Asians and "other" residual category. The finding, once again is inconsistent with the history of European immigration. Finally, although Latinos are more exogamous, they preferred a Hispanic spouse than a non-Hispanic, which could be attributed to the common Spanish language shared by them. In contrast, lack of a common language among Asians might be contributing to their lowest intermarriage rate with other Asians, irrespective of gender.

  8. Fertility behaviour of recent immigrants to Israel

    Directory of Open Access Journals (Sweden)

    2004-03-01

    Full Text Available The fertility practices of immigrants are a particularly interesting field of study for demographers, providing an insight into the fertility behaviour of individuals when both the society and the individual undergo a period of rapid change. This paper describes and compares the fertility behaviour of two large groups of immigrants, from the former Soviet Union (FSU and from Ethiopia to Israel in the last 20 years. The changes in fertility behaviour undergone in the same society and at the same time by two very different groups are examined. The findings reveal that the fertility behaviour of immigrants is indeed changing. The fertility of FSU immigrants is increasing and that of the Ethiopian immigrants decreasing, with accompanying changes in the proximate determinants of fertility. Although the fertility of immigrants is becoming more similar to that of the receiving society, the methods employed to achieve the fertility change are not necessarily similar, and, in some cases, diverge from the norms of the receiving society.

  9. Channel Modeling

    Science.gov (United States)

    Schmitz, Arne; Schinnenburg, Marc; Gross, James; Aguiar, Ana

    For any communication system the Signal-to-Interference-plus-Noise-Ratio of the link is a fundamental metric. Recall (cf. Chapter 9) that the SINR is defined as the ratio between the received power of the signal of interest and the sum of all "disturbing" power sources (i.e. interference and noise). From information theory it is known that a higher SINR increases the maximum possible error-free transmission rate (referred to as Shannon capacity [417] of any communication system and vice versa). Conversely, the higher the SINR, the lower will be the bit error rate in practical systems. While one aspect of the SINR is the sum of all distracting power sources, another issue is the received power. This depends on the transmitted power, the used antennas, possibly on signal processing techniques and ultimately on the channel gain between transmitter and receiver.

    Channeling of water flow and tracer transport in real fractures in a granite body at Stripa have been investigated experimentally. The experimental site was located 360 m below the ground level. Two kinds of experiments were performed. In the single hole experiments, 20 cm diameter holes were drilled about 2.5 m into the rock in the plane of the fracture. Specially designed packers were used to inject water into the fracture in 5 cm intervals all along the fracture trace in the hole. The variation of the injection flowrates along the fracture were used to determine the transmissivity variations in the fracture plane. Detailed photographs were taken from inside the hole and the visual fracture aperture was compared with the injection flowrates in the same locations. Geostatistical methods were used to evaluate the results. Five holes were measured in great detail. In addition 7 holes were drilled and scanned by simpler packer systems. A double hole experiment was performed where two parallel holes were drilled in the same fracture plane at nearly 2 m distance. Pressure pulse tests were made between the holes in both directions. Tracers were injected in 5 locations in one hole and monitored for in many locations in the other hole. The single hole experiment and the double hole experiment show that most of the fracture planes are tight but that there are open sections which form connected channels over distances of at least 2 meters. It was also found in the double hole experiment that the investigated fracture was intersected by at least one fracture between the two holes which diverted a large amount of the injected tracers to several distant locations at the tunnel wall.

    Hydromodification (changes in watershed hydrologic characteristics, and the resulting hydraulics and channel forms due to urbanization) is ubiquitous in Southern California. In this region, the effects of hydromodification are driven and compounded by the arid/semiarid climate, high relief, erodible soils, high urbanization rates, and relatively low frequency of retention/detention. We conducted a preliminary survey of over 50 stream reaches along a gradient from least disturbed to fully urbanized. All stages of the Channel Evolution Model (CEM) of Schumm et al. (1984) were observed, from stable to degrading, widening, aggrading, and quasi-equilibrium channels. Several sites have CEM stages II through V in close proximity due to headcutting, hardpoints, and infrastructure. We also observed channels in undeveloped watersheds impacted by downstream urbanization via headcutting. A range of intervention measures was observed, with the frequent evolutionary endpoint as a concrete engineered flood control channel. We also observed multiple channel evolution sequences that deviate from the CEM for single-thread, incising channels. An alternative channel response, particularly on smaller urbanized streams is a stabilized, vegetation encroached low-flow channel with regular baseflow supplied by residential irrigation runoff. The limited cases of unimpacted streams that remain tend to be high gradient, high energy systems that are naturally proximate to the transition between braided and meandering form for a given sediment size.

    Previous studies have reported that the nutritional status of Vietnamese female marriage immigrants in Korea is inadequate. And the mediation of acculturation stress can contribute to problems in their eating practices and dietary intakes. This study examines an association between psychological distress and inadequate dietary intake in Vietnamese female marriage immigrants living in Korea. A cross-sectional study analyzed baseline data (n=570) from the Cohort of Intermarried Women in Korea. Daily nutrient intakes were compared according to the quartiles of distress scores assessed by the Psychological Well-Being Index-Short Form. One-way analysis of variance and chi(2) tests were used to compare eating practices and nutrient intake across quartiles of psychological distress. Subjects in the highest stress scores were more likely to skip breakfast and to change their dietary habits after living in Korea than those in groups with low stress scores. Analyses of the subjects' Mini Dietary Assessments revealed that those with the highest stress scores were less likely to consume milk or dairy products, eat regular meals, or have balanced diets than those with the lowest stress scores. Nutrient intakes were found to be inadequate in the subjects, and those with the highest stress scores showed lower consumptions of energy, carbohydrate, protein, fat, calcium, zinc, thiamin, riboflavin, and folate compared to those with the lowest scores. The prevalence of underweight (body mass index [calculated as kg/m(2)] Korea was negatively associated with dietary intake. These findings can assist dietetics practitioners working with minority immigrants because such information is important in designing appropriate strategies for dietary counseling. A follow-up study should address the underlying mechanisms of the observed diet-distress association in Vietnamese marriage immigrant women in Korea, as well as other various ethnic minority immigrants in Korea.

    Researchers have found breastfeeding disparities between immigrant and native-born women in many countries. However, most studies on immigration and breastfeeding practices have been in Western countries. The aim of this study was to examine the effect of length of time since immigration on the breastfeeding practices of Mainland Chinese immigrants living in Hong Kong. We recruited 2704 mother-infant pairs from the postnatal wards of four public hospitals in Hong Kong. We examined the effect of migration status on the duration of any and exclusive breastfeeding. Breastfeeding duration was progressively shorter as the time since immigration increased. When compared with mothers who had lived in Hong Kong for Hong Kong-born participants had a 30% higher risk of stopping any breastfeeding (hazard ratio [HR] 1.34 [95% confidence interval {CI} 1.10-1.63]) and exclusive breastfeeding (HR 1.33 [95% CI 1.11-1.58]). In both Hong Kong-born and immigrant participants, breastfeeding cessation was associated with return to work postpartum and the husband's preference for infant formula or mixed feeding. Intention to exclusively breastfeed and to breastfeed for >6 months, and previous breastfeeding experience substantially reduced the risk of breastfeeding cessation for both Hong Kong-born and immigrant participants. Health care professionals should consider immigration history in their assessment of pregnant women and provide culturally adapted breastfeeding support and encouragement to this population. © 2017 Wiley Periodicals, Inc.

    Despite a rising incidence of inflammatory bowel disease (IBD) in Hispanics in the United States, there are no studies examining the relationship between immigrant generation and IBD onset among Hispanics. To determine whether age of IBD diagnosis, time from immigration to IBD diagnosis and IBD phenotype, differed across immigration periods in South Florida Cuban immigrants. This was a cohort of consecutively identified Cuban-born adults who developed IBD in the United States and were followed in gastroenterology (GI) clinic. We divided time cohorts of immigration by historical relevance: before 1980, 1980-1994 and 1995-to-present. We examined differences across time cohorts in diagnosis age, time from immigration to IBD diagnosis, and IBD phenotype (ie, IBD type, disease location). A total of 130 Cuban patients with IBD were included. Age of IBD diagnosis was older in Cubans arriving before 1980 than in those arriving between 1980-1994 or after 1995 (44.7 vs 33.79 and 33.71, respectively, Pimmigration and diagnosis was shorter in patients arriving to the US after 1980 (31.77 years, Standard deviation (SD) 12.83 (immigration in Cubans, suggesting that environmental changes either in the United States, Cuba or both are resulting in faster IBD onset in younger immigrant generations.

    To examine the effect of immigration on the self-reported oral health of immigrants to Canada over a 4-year period. The study used Statistics Canada's Longitudinal Survey of Immigrants to Canada (LSIC 2001-2005). The target population comprised 3976 non-refugee immigrants to Canada. The dependent variable was self-reported dental problems. The independent variables were as follows: age, sex, ethnicity, income, education, perceived discrimination, history of social assistance, social support, and official language proficiency. A generalized estimation equation approach was used to assess the association between dependent and independent variables. After 2 years, the proportion of immigrants reporting dental problems more than tripled (32.6%) and remained approximately the same at 4 years after immigrating (33.3%). Over time, immigrants were more likely to report dental problems (OR = 2.77; 95% CI 2.55-3.02). An increase in self-reported dental problems over time was associated with sex, history of social assistance, total household income, and self-perceived discrimination. An increased likelihood of reporting dental problems occurred over time. Immigrants should arguably constitute an important focus of public policy and programmes aimed at improving their oral health and access to dental care in Canada. © 2015 John Wiley & Sons A/S.

    Full Text Available The changes related to globalisation and to the increasing presence of immigrants in Western Europe place the traditional concept of citizenship in crisis: formal citizenship is no longer a means to inclusion for an increasing number of people, such as non-EU immigrants. A research project, like the one presented in this paper, which seeks to study immigrants' citizenship demands (MEZZADRA, 2001, needs, therefore, to concentrate on a more pragmatic meaning of citizenship. Partly following the suggestions of some authors who have researched this topic, I have built a multidimensional model for analysing immigrants' self-organisation and political participation in Italy and, in particular, in the Veneto region. The model takes into consideration four factors that can have an influence on immigrants' civic and political participation, namely: 1 supranational and national context, 2 local immigration field, 3 infra-political sphere, cultural background, transnational dimension and 4 some variables related to the individual (like gender, age, length of time in host country, etc. The findings show that these factors are important in shaping "immigrants' citizenship demands" and that for many immigrants formal citizenship is neither a salient issue nor a fundamental tool for participation in the society of arrival.

    To determine the prevalence rates and characteristics of past-year mental health consultation for Ontario's adult (18 + years old) immigrant populations. The Canadian Community Health Survey (CCHS) 2012 was used to calculate the prevalence rates of past-year mental health consultation by service provider type. Characteristics associated with mental health consultation were determined by carrying out multivariable logistic regression analysis on merged CCHS 2008-2012 data. Adult immigrant populations in Ontario (n = 3995) had lower estimated prevalence rates of past-year mental health consultation across all service provider types compared to Canadian-born populations (n = 14,644). Amongst those who reported past-year mental health consultation, 57.89% of Ontario immigrants contacted their primary care physician, which was significantly higher than the proportion who consulted their family doctor from Canadian-born populations (45.31%). The factors of gender, age, racial/ethnic background, education level, working status, food insecurity status, self-perceived health status, smoking status, alcohol drinking status, years since immigration, and age at time of immigration were significantly associated with past-year mental health consultation for immigrant populations. Ontario's adult immigrant populations most commonly consult their family doctor for mental health care. Potential exists for expanding the mental health care role of primary care physicians as well as efforts to increase accessibility of specialized mental health services. Integrated, coordinated care where primary care physicians, specialized mental health professionals, social workers, and community educators, etc. working together in a sort of "one-stop-shop" may be the most effective way to mitigate gaps in the mental health care system.

    Several acculturation theories note the importance of surrounding context, but few studies describe neighborhood influences on immigrant adaptation. The purpose of this study was to examine relationships among neighborhood immigrant concentration, acculturation, and alienation for 151 women aged 44-80 from the former Soviet Union who lived in the US fewer than 13 years. Participants resided in 65 census tracts in the Chicago area with varying concentrations of Russian-speaking and diverse immigrants. Results from self-report questionnaires suggest that the effect of acculturation on alienation varies depending on neighborhood characteristics. The study also demonstrates the complexity of individual and contextual influences on immigrant adoption. Understanding these relationships is important for developing community-based and neighborhood-level interventions to enhance the mental health of immigrants.

    This paper attempts to supply information on what motivated some 7000 Jewish divorcees to leave their countries of origin in the last decade and settle in Israel. The study also examines the differences in social integration of immigrant divorcees who came to Israel from different political systems--authoritarian or democratic regimes. Finally, the study examines the extent to which immigrant divorcees, who generally arrive in Israel with children, are to be considered as a "high risk" social group requiring special attention and particular aid. Of the 287,487 immigrants aged 15 years and over who arrived in Israel between 1970-1980, 53.7% were women (sex ratio: 860 males per 1000 females), and 3.6% were divorced. The findings indicate that there are significant differences between divorcees from Anglophone and Eastern European countries in their motivation for immigrating to Israel. The former decide to immigrate primarily for individual reasons--generally after divorce--expecting that immigration will increase chances of remarriage. In contrast, those who came from Eastern Europe are motivated by political, economic, and ideological reasons; the issue of immigration often sparks the divorce crisis. Divorcees from Anglophone countries are less socially isolated, more likely to meet veteran Israelis, and more satisfied with their life in Israel. Eastern European divorcees usually restrict their social contact to encounters with other immigrants from their country of origin, are less satisfied with their life in Israel, and feel themselves more isolated and frustrated. Despite the difficulties encountered by this group, it was found that there are no marked differences between divorcees and married immigrant women in social integration. In Israel, immigrant divorcees cannot be considered as a "high risk" social group.

  18. Higher education and children in immigrant families.

    Baum, Sandy; Flores, Stella M

    2011-01-01

    The increasing role that immigrants and their children, especially those from Latin America, are playing in American society, Sandy Baum and Stella Flores argue, makes it essential that as many young newcomers as possible enroll and succeed in postsecondary education. Immigrant youths from some countries find the doors to the nation's colleges wide open. But other groups, such as those from Latin America, Laos, and Cambodia, often fail to get a postsecondary education. Immigration status itself is not a hindrance. The characteristics of the immigrants, such as their country of origin, race, and parental socioeconomic status, in addition to the communities, schools, and legal barriers that greet them in the United States, explain most of that variation. Postsecondary attainment rates of young people who come from low-income households and, regardless of income or immigration status, whose parents have no college experience are low across the board. Exacerbating the financial constraints is the reality that low-income students and those whose parents have little education are frequently ill prepared academically to succeed in college. The sharp rise in demand for skilled labor over the past few decades has made it more urgent than ever to provide access to postsecondary education for all. And policy solutions, say the authors, require researchers to better understand the differences among immigrant groups. Removing barriers to education and to employment opportunities for undocumented students poses political, not conceptual, problems. Providing adequate funding for postsecondary education through low tuition and grant aid is also straightforward, if not easy to accomplish. Assuring that Mexican immigrants and others who grow up in low-income communities have the opportunity to prepare themselves academically for college is more challenging. Policies to improve the elementary and secondary school experiences of all children are key to improving the postsecondary

  1. Hierarchical regular small-world networks

    Boettcher, Stefan; Goncalves, Bruno; Guclu, Hasan

    2008-01-01

    Two new networks are introduced that resemble small-world properties. These networks are recursively constructed but retain a fixed, regular degree. They possess a unique one-dimensional lattice backbone overlaid by a hierarchical sequence of long-distance links, mixing real-space and small-world features. Both networks, one 3-regular and the other 4-regular, lead to distinct behaviors, as revealed by renormalization group studies. The 3-regular network is planar, has a diameter growing as √N with system size N, and leads to super-diffusion with an exact, anomalous exponent d w = 1.306..., but possesses only a trivial fixed point T c = 0 for the Ising ferromagnet. In turn, the 4-regular network is non-planar, has a diameter growing as ∼2 √(log 2 N 2 ) , exhibits 'ballistic' diffusion (d w = 1), and a non-trivial ferromagnetic transition, T c > 0. It suggests that the 3-regular network is still quite 'geometric', while the 4-regular network qualifies as a true small world with mean-field properties. As an engineering application we discuss synchronization of processors on these networks. (fast track communication)

  3. Coupling regularizes individual units in noisy populations

    2010-01-01

    The regularity of a noisy system can modulate in various ways. It is well known that coupling in a population can lower the variability of the entire network; the collective activity is more regular. Here, we show that diffusive (reciprocal) coupling of two simple Ornstein-Uhlenbeck (O-U) processes can regularize the individual, even when it is coupled to a noisier process. In cellular networks, the regularity of individual cells is important when a select few play a significant role. The regularizing effect of coupling surprisingly applies also to general nonlinear noisy oscillators. However, unlike with the O-U process, coupling-induced regularity is robust to different kinds of coupling. With two coupled noisy oscillators, we derive an asymptotic formula assuming weak noise and coupling for the variance of the period (i.e., spike times) that accurately captures this effect. Moreover, we find that reciprocal coupling can regularize the individual period of higher dimensional oscillators such as the Morris-Lecar and Brusselator models, even when coupled to noisier oscillators. Coupling can have a counterintuitive and beneficial effect on noisy systems. These results have implications for the role of connectivity with noisy oscillators and the modulation of variability of individual oscillators.

    Using the scalar prototype and gauge theory as the simplest possible examples, diagrammatic methods are developed for the recently proposed phase-space form of continuum regularization. A number of one-loop and all-order applications are given, including general diagrammatic discussions of the nogrowth theorem and the uniqueness of the phase-space stochastic calculus. The approach also generates an alternate derivation of the equivalence of the large-β phase-space regularization to the more conventional coordinate-space regularization. (orig.)

  6. J-regular rings with injectivities

    OpenAIRE

    Shen, Liang

    2010-01-01

    A ring $R$ is called a J-regular ring if R/J(R) is von Neumann regular, where J(R) is the Jacobson radical of R. It is proved that if R is J-regular, then (i) R is right n-injective if and only if every homomorphism from an $n$-generated small right ideal of $R$ to $R_{R}$ can be extended to one from $R_{R}$ to $R_{R}$; (ii) R is right FP-injective if and only if R is right (J, R)-FP-injective. Some known results are improved.

    Asian communities in North America include large numbers of immigrants with limited English proficiency. Hepatitis B virus (HBV) infection is endemic in most Asian countries and, therefore, Asian immigrant groups have high rates of chronic HBV infection. We conducted a group-randomized trial to evaluate the effectiveness of a hepatitis B English as a second language (ESL) educational curriculum for Asian immigrants. Eighty ESL classes were randomized to experimental (hepatitis B education) or control (physical activity education) status. Students who reported they had not received a HBV test (at baseline) completed a follow-up survey 6 months after randomization. The follow-up survey assessed recent HBV testing and HBV-related knowledge. Provider reports were used to verify self-reported HBV tests. The study group included 218 students who reported they had not been tested for HBV. Follow-up surveys were completed by 180 (83%) of these students. Provider records verified HBV testing for 6% of the experimental group students and 0% of the control group students (P = 0.02). Experimental group students were significantly (P ESL curriculum had a meaningful impact on HBV-related knowledge and a limited impact on HBV testing levels. Future research should evaluate the effectiveness of ESL curricula for other immigrant groups and other health topics, as well as other intervention approaches to increasing levels of HBV testing in Asian immigrant communities.

  12. Geometric regularizations and dual conifold transitions

    International Nuclear Information System (INIS)

    Landsteiner, Karl; Lazaroiu, Calin I.

    2003-01-01

    We consider a geometric regularization for the class of conifold transitions relating D-brane systems on noncompact Calabi-Yau spaces to certain flux backgrounds. This regularization respects the SL(2,Z) invariance of the flux superpotential, and allows for computation of the relevant periods through the method of Picard-Fuchs equations. The regularized geometry is a noncompact Calabi-Yau which can be viewed as a monodromic fibration, with the nontrivial monodromy being induced by the regulator. It reduces to the original, non-monodromic background when the regulator is removed. Using this regularization, we discuss the simple case of the local conifold, and show how the relevant field-theoretic information can be extracted in this approach. (author)

  13. Feeding styles and evening family meals among recent immigrants

    Science.gov (United States)

    2013-01-01

    The protective effect of family meals on unhealthy weight gain and diet has been shown across multiple age groups; however, it is unknown whether a similar effect is present among diverse immigrant populations. In addition, little research has focused on factors associated with the frequency of evening family meals, such as feeding styles (how parents interact with their child around feeding). Therefore the goals of this paper are to explore the 1) association between the frequency of evening family meals and child weight status among new immigrant families, and 2) influence of immigrant mothers’ feeding styles on the frequency of evening family meals. Baseline self-reported socio-demographic information and measured heights and weights were collected for both mother and child (age range: 3–12 years) among 387 mother-child dyads enrolled in Live Well, a community-based, participatory-research, randomized controlled lifestyle intervention to prevent excessive weight gain in recent (eating dinner in front of the TV, acculturation and responses to the Caregiver’s Feeding Styles Questionnaire (CFSQ) were also obtained from the mother. Children were categorized as “eating evening family meals regularly” if they had an evening family meal ≥5 times per week. Overall, 20% of children were overweight and 25% were obese. Less than half (40.9%) of families had regular evening family meals. In multivariate analyses, adjusting for covariates, children who were overweight/obese were significantly less likely to have ≥5 evening family meals/week compared with normal weight children (OR = 0.51, 95% CI 0.32-0.82) . Mothers who had a low demanding/high responsive or a low demanding/low responsive feeding style, were less likely to have ≥5 evening family meals/week compared to mothers with a high demanding/high responsive feeding style (OR = 0.41, 95% CI 0.18-0.0.96, OR = 0.33, 95% CI 0.13-0.87, respectively).

    The act of immigration brings with it numerous major life changes and requires considerable social readjustment. Immigrants are, however, seldom offered specific training in how to effectively interact in a new culture. This paper describes an initial preventive groupwork effort to help English-speaking immigrants living in an Israeli absorption center to adjust successfully to life in a new culture. Suggestions for future preventive interventions with immigrants are considered.

    Public debate on immigration focuses on its effects on wages and employment, yet the discussion typically fails to consider the effects of immigration on working conditions that affect workers' health. There is growing evidence that immigrants are more likely than natives to work in risky jobs, as they are more inclined to take on physically intensive tasks. Recent studies show that as immigration rises, native workers are pushed into less demanding jobs. Such market adjustments have positive...

  6. Epidemiological Paradox or Immigrant Vulnerability? Obesity Among Young Children of Immigrants

    Science.gov (United States)

    Baker, Elizabeth H.; Rendall, Michael S.; Weden, Margaret M.

    2015-01-01

    According to the “immigrant epidemiological paradox,” immigrants and their children enjoy health advantages over their U.S.-born peers—advantages that diminish with greater acculturation. We investigated child obesity as a potentially significant deviation from this paradox for second-generation immigrant children. We evaluated two alternate measures of mother's acculturation: age at arrival in the United States and English language proficiency. To obtain sufficient numbers of second-generation immigrant children, we pooled samples across two related, nationally representative surveys. Each included measured (not parent-reported) height and weight of kindergartners. We also estimated models that alternately included and excluded mother's pre-pregnancy weight status as a predictor. Our findings are opposite to those predicted by the immigrant epidemiological paradox: children of U.S.-born mothers were less likely to be obese than otherwise similar children of foreign-born mothers; and the children of the least-acculturated immigrant mothers, as measured by low English language proficiency, were the most likely to be obese. Foreign-born mothers had lower (healthier) pre-pregnancy weight than U.S.-born mothers, and this was protective against their second-generation children's obesity. This protection, however, was not sufficiently strong to outweigh factors associated or correlated with the mothers' linguistic isolation and marginal status as immigrants. PMID:26111970

  7. Immigrant Sexual Citizenship: Intersectional Templates among Mexican Gay Immigrants to the United States

    Science.gov (United States)

    Epstein, Steven; Carrillo, Héctor

    2014-01-01

    Existing literature on sexual citizenship has emphasized the sexuality-related claims of de jure citizens of nation-states, generally ignoring immigrants. Conversely, the literature on immigration rarely attends to the salience of sexual issues in understanding the social incorporation of migrants. This article seeks to fill the gap by theorizing and analyzing immigrant sexual citizenship. While some scholars of sexual citizenship have focused on the rights and recognition granted formally by the nation-state and others have stressed more diffuse, cultural perceptions of community and local belonging, we argue that the lived experiences of immigrant sexual citizenship call for multiscalar scrutiny of templates and practices of citizenship that bridge national policies with local connections. Analysis of ethnographic data from a study of 76 Mexican gay and bisexual male immigrants to San Diego, California reveals the specific citizenship templates that these men encounter as they negotiate their intersecting social statuses as gay/bisexual and as immigrants (legal or undocumented); these include an “asylum” template, a “rights” template, and a “local attachments” template. However, the complications of their intersecting identities constrain their capacity to claim immigrant sexual citizenship. The study underscores the importance of both intersectional and multiscalar approaches in research on citizenship as social practice. PMID:25013360

    2017-04-01

    To compare functional health literacy (HL) levels in three immigrant groups to those of the German- and Italian-speaking non-immigrant population in Switzerland. Moreover, to investigate whether language-independent, respectively language-dependent, functional HL and variables of acculturation were associated with self-reported health status among immigrants. Language-independent HL was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) in the respective native languages. Language-dependent HL was measured using Brief Health Literacy Screeners (BHLS) asking about participants' confidence in understanding medical information in the language of the host country. Measures of acculturation included length of stay and age when taking residency in Switzerland. In particular Albanian- and Portuguese-speaking immigrants had lower levels of functional HL. In unadjusted analysis "age when taking residency in Switzerland" was associated with the BHLS. Adjusted analysis showed that the BHLS were significantly associated with self-reported health among all immigrant groups (p≤0.01). Functional HL that is dependent on understanding of medical information in the language of the new host country is a better predictor for self-reported health status among immigrants than language-independent HL. In the clinical setting limited functional HL might be a significant obstacle to successful disease treatment and prevention in immigrants. Copyright © 2016 Elsevier Ireland Ltd.

    We argue that important, overlooked differences in what we call the ‘cultural armature’ of Portland, Maine, and Danbury, Connecticut help explain the variation in how each city received new immigrants in recent years. Portland has a long history of contact with the outside world and used its cosmopolitan character to promote urban redevelopment and welcome immigrants from a range of countries of origin. Danbury’s small-town, insular outlook, and the fact that most of its newcomers came from a single country of origin – some without legal documents – made immigrants’ welcome more fragmented. While leaders in both cities speak of multiculturalism and tolerance, the ‘cultural armature’ of each led city leaders to put that talk into action differently. We describe how we see this ‘cultural armature’ at work and argue that it – in combination with demographic realities – led immigrants to be more warmly welcomed in Portland than in Danbury.

    2016-12-01

    Full Text Available Immigration became one of the relevant economic topics in recent years. Over the centuries millions of people have migrated, despite the physical, cultural etc. obstacles, to other lands in search of better lives for themselves and their children. In the context of development, globalization and labor market mobility, it is necessary to further analyze the determinants and consequences of migration not only on the host country, but also on the sending country. The increased interest and availability of data keeps this subject in the attention of economists all over the world. In this case an increase in immigration became very significant ıssue for policymakers. The aims of this study are to describe immigration growth tendencies and to answer how much is the average growth rate of foreıgn born population. Thus, in order to measure the native and foreign-born unemployed migrants, twenty-seven OECD countries were used in this research paper.

  1. Regularization and the potential of effective field theory in nucleon-nucleon scattering

    International Nuclear Information System (INIS)

    Phillips, D.R.

    1998-04-01

    This paper examines the role that regularization plays in the definition of the potential used in effective field theory (EFT) treatments of the nucleon-nucleon interaction. The author considers N N scattering in S-wave channels at momenta well below the pion mass. In these channels (quasi-)bound states are present at energies well below the scale m π 2 /M expected from naturalness arguments. He asks whether, in the presence of such a shallow bound state, there is a regularization scheme which leads to an EFT potential that is both useful and systematic. In general, if a low-lying bound state is present then cutoff regularization leads to an EFT potential which is useful but not systematic, and dimensional regularization with minimal subtraction leads to one which is systematic but not useful. The recently-proposed technique of dimensional regularization with power-law divergence subtraction allows the definition of an EFT potential which is both useful and systematic

    The risk of certain psychiatric disorders is elevated among immigrants. To date, no population studies on immigrant health have addressed eating disorders. We examined whether risk of eating disorders in first- and second-generation immigrants differs from native-born Danes and Swedes. All individuals born 1984-2002 (Danish cohort) and 1989-1999 (Swedish cohort) and residing in the respective country on their 10th birthday were included. They were followed up for the development of eating disorders based on out-patient and in-patient data. The risks of all eating disorder types were lower among first-generation immigrants compared to the native populations: Incidence-rate ratio (95% confidence interval) was 0.39 (0.29, 0.51) for anorexia nervosa, 0.60 (0.42, 0.83) for bulimia nervosa, and 0.62 (0.47, 0.79) for other eating disorders in Denmark and 0.27 (0.21, 0.34) for anorexia nervosa, 0.30 (0.18, 0.51) for bulimia nervosa, and 0.39 (0.32, 0.47) for other eating disorders in Sweden. Likewise, second-generation immigrants by both parents were at lower risk, whereas those with only one foreign-born parent were not. The decreased risk of eating disorders among immigrants is opposite to what has been observed for other psychiatric disorders, particularly schizophrenia. Possible explanations include buffering sociocultural factors and underdetection in health care. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  3. Immigration Stress and Alcohol Use Severity Among Recently Immigrated Hispanic Adults: Examining Moderating Effects of Gender, Immigration Status, and Social Support.

    Identifying and understanding determinants of alcohol use behavior among Hispanic immigrants is an increasingly significant public health concern. Although prior research has examined associations of cultural stressors with alcohol use among Hispanics, few studies have tested these associations among recent adult immigrants. As such, this study aimed to examine (a) the association of immigration stress on alcohol use severity among recently immigrated Hispanic adults (≤ 1 year in the United States) and (b) the moderating effects of gender, immigration status, and social support. A hierarchical multiple regression and moderation analyses were conducted on a sample of 527 participants in South Florida. Results indicated that, after controlling for demographic variables, preimmigration drinking behavior, and dimensions of social support, the association of higher immigration stress with higher alcohol use severity was statistically significant. Moderation analyses indicated that immigration stress had a statistically significant association with alcohol use severity among men, but not women. Also, dimensions of social support consistently reduced the deleterious effect of immigration stress on alcohol use severity. This study adds to the scarce literature on cultural stressors and alcohol use among recent Hispanic immigrants. Findings suggest that it may be important to design gender-specific interventions and that increasing levels of social support may offset the effects of immigration stress on alcohol use. © 2016 Wiley Periodicals, Inc.

  7. Immigrants: A Study Case for N. Greece

    Directory of Open Access Journals (Sweden)

    Maria Vlachadi

    2014-05-01

    Full Text Available It is a fact that the phenomenon of immigration constitutes, during the last years, the view of a new social and economic reality for the societies of most western European countries. Greece has received for the first time, during the 1990s, thousands of economic immigrants who appear not only in the big city centers but also in small country towns. Immigrants probably constitute the most discussed issue in the Modern Greek society, in an economic conjuncture in which the economic crisis has functioned in a catalytic way for the diffusion of insecurity in the native population (Biblionet, 2012. The Greek state was not ready to accept such a large number of immigrants in so little time. It showed hesitance and could not keep a steady position as far as the promotion of a necessary institutional framework for their integration in the Greek society was concerned. This initial surprise has never been overcome. In Greece, as well as in the rest of the European South, the majority of the immigrants entering the country illegally have supplied the informal working market. Even when they become legal, the available working positions for them presuppose low specialization with low payments, hard work and limited opportunities of improvement of their social and occupational status. Although the immigration phenomenon is usually approached in a national level, the local level is considered the most suitable one to deal with the interaction of its economic, social, political and cultural dimensions. Recent studies have shown their positive contribution in the revival of Greek agriculture and Greek agricultural districts in general. Within the scale of the Greek community and the degree in which it constitutes a place of constant flow of human resources, it is inevitable the general presence of immigrants to raise issues of mutual infiltrations among different national populations within which there arise interaction issues and intercultural interdependence

  16. Improvements in GRACE Gravity Fields Using Regularization

    Science.gov (United States)

    Save, H.; Bettadpur, S.; Tapley, B. D.

    2008-12-01

    The unconstrained global gravity field models derived from GRACE are susceptible to systematic errors that show up as broad "stripes" aligned in a North-South direction on the global maps of mass flux. These errors are believed to be a consequence of both systematic and random errors in the data that are amplified by the nature of the gravity field inverse problem. These errors impede scientific exploitation of the GRACE data products, and limit the realizable spatial resolution of the GRACE global gravity fields in certain regions. We use regularization techniques to reduce these "stripe" errors in the gravity field products. The regularization criteria are designed such that there is no attenuation of the signal and that the solutions fit the observations as well as an unconstrained solution. We have used a computationally inexpensive method, normally referred to as "L-ribbon", to find the regularization parameter. This paper discusses the characteristics and statistics of a 5-year time-series of regularized gravity field solutions. The solutions show markedly reduced stripes, are of uniformly good quality over time, and leave little or no systematic observation residuals, which is a frequent consequence of signal suppression from regularization. Up to degree 14, the signal in regularized solution shows correlation greater than 0.8 with the un-regularized CSR Release-04 solutions. Signals from large-amplitude and small-spatial extent events - such as the Great Sumatra Andaman Earthquake of 2004 - are visible in the global solutions without using special post-facto error reduction techniques employed previously in the literature. Hydrological signals as small as 5 cm water-layer equivalent in the small river basins, like Indus and Nile for example, are clearly evident, in contrast to noisy estimates from RL04. The residual variability over the oceans relative to a seasonal fit is small except at higher latitudes, and is evident without the need for de-striping or

  17. Properties of regular polygons of coupled microring resonators.

    Chremmos, Ioannis; Uzunoglu, Nikolaos

    2007-11-01

    The resonant properties of a closed and symmetric cyclic array of N coupled microring resonators (coupled-microring resonator regular N-gon) are for the first time determined analytically by applying the transfer matrix approach and Floquet theorem for periodic propagation in cylindrically symmetric structures. By solving the corresponding eigenvalue problem with the field amplitudes in the rings as eigenvectors, it is shown that, for even or odd N, this photonic molecule possesses 1 + N/2 or 1+N resonant frequencies, respectively. The condition for resonances is found to be identical to the familiar dispersion equation of the infinite coupled-microring resonator waveguide with a discrete wave vector. This result reveals the so far latent connection between the two optical structures and is based on the fact that, for a regular polygon, the field transfer matrix over two successive rings is independent of the polygon vertex angle. The properties of the resonant modes are discussed in detail using the illustration of Brillouin band diagrams. Finally, the practical application of a channel-dropping filter based on polygons with an even number of rings is also analyzed.

    Full Text Available A fractal-skeletal based channel network (F-SCN model is proposed. Four regular sided initiator-basins are transformed as second order fractal basins by following a specific generating mechanism with non-random rule. The morphological skeletons, hereafter referred to as channel networks, are extracted from these fractal basins. The morphometric and fractal relationships of these F-SCNs are shown. The fractal dimensions of these fractal basins, channel networks, and main channel lengths (computed through box counting method are compared with those of estimated length–area measures. Certain morphometric order ratios to show fractal relations are also highlighted.

One in seven had found out about jobs through friends.

  2. Regular Expression Matching and Operational Semantics

    Directory of Open Access Journals (Sweden)

    Asiri Rathnayake

    2011-08-01

    Full Text Available Many programming languages and tools, ranging from grep to the Java String library, contain regular expression matchers. Rather than first translating a regular expression into a deterministic finite automaton, such implementations typically match the regular expression on the fly. Thus they can be seen as virtual machines interpreting the regular expression much as if it were a program with some non-deterministic constructs such as the Kleene star. We formalize this implementation technique for regular expression matching using operational semantics. Specifically, we derive a series of abstract machines, moving from the abstract definition of matching to increasingly realistic machines. First a continuation is added to the operational semantics to describe what remains to be matched after the current expression. Next, we represent the expression as a data structure using pointers, which enables redundant searches to be eliminated via testing for pointer equality. From there, we arrive both at Thompson's lockstep construction and a machine that performs some operations in parallel, suitable for implementation on a large number of cores, such as a GPU. We formalize the parallel machine using process algebra and report some preliminary experiments with an implementation on a graphics processor using CUDA.

  3. Regularities, Natural Patterns and Laws of Nature

    Directory of Open Access Journals (Sweden)

    Stathis Psillos

    2014-02-01

    Full Text Available  The goal of this paper is to sketch an empiricist metaphysics of laws of nature. The key idea is that there are regularities without regularity-enforcers. Differently put, there are natural laws without law-makers of a distinct metaphysical kind. This sketch will rely on the concept of a natural pattern and more significantly on the existence of a network of natural patterns in nature. The relation between a regularity and a pattern will be analysed in terms of mereology.  Here is the road map. In section 2, I will briefly discuss the relation between empiricism and metaphysics, aiming to show that an empiricist metaphysics is possible. In section 3, I will offer arguments against stronger metaphysical views of laws. Then, in section 4 I will motivate nomic objectivism. In section 5, I will address the question ‘what is a regularity?’ and will develop a novel answer to it, based on the notion of a natural pattern. In section 6, I will raise the question: ‘what is a law of nature?’, the answer to which will be: a law of nature is a regularity that is characterised by the unity of a natural pattern.

    2017-01-01

    This study analyzes the differences in the prevalence of insomnia symptoms and nonrestorative sleep (NRS) between people born in Spain and immigrants from 7 countries with most immigrants in Spain. Data come from the 2006 Spanish National Health Survey. The sample was composed of all individuals aged 16 to 64 years from Spain and the 7 countries with most immigrants in Spain (N = 22,224). In both sexes, people from Bolivia had a higher prevalence of insomnia symptoms and NRS. Conversely, people from Ecuador, Morocco, and Romania had less insomnia symptoms and NRS than Spanish-born participants. No differences were found between Spanish-born participants and Colombian, Peruvian, and Argentinian women. Poor living conditions in the country of origin and in the host country, discrimination, and culturally related lifestyles could be related to poorer sleep health among Bolivian men. Acculturation may explain the similar sleep health patterns noted between Spanish-born participants and long-term immigrants.

    Full Text Available Starting from the assumption that „fear” or „the threat feeling” felt on immigrants as a group is a strong predictor of negative reaction and actions against these out-groups we are trying to identify in this paper the social predictors of these feelings. If most studies on anti-immigrant attitudes are oriented mainly to economic effects, city or municipality effects we included in our analysis not only the clasical variable like education, income, age, gender, professional status, citizenship as in previous studies, but also the religious affiliation and immigration descendence. Starting from EVS 2008 data we obtained results that confirms other studies and also we identified the positive strong effect of religious denomination on immigration threat feelings.

    Science.gov (United States)

    Sakamoto, Izumi; Wei, Yi; Truong, Lele

    2008-12-01

    While the idea of acculturation (Berry 1997) was originally proposed as the mutual change of both parties (e.g., immigrants and the host society), the change processes of host societies are neglected in research. A grounded theory study explored the efforts of human service organizations to 'acculturate' to an increasingly diverse immigrant population, through interviews conducted with service providers serving Mainland Chinese immigrants. Acculturation efforts of human service organizations (mezzo-level acculturation) were often needs-driven and affected by the political will and resultant funding programs (macro-level forces). Even with limitations, human service organizations commonly focused on hiring Mainland Chinese immigrants to reflect the changing demographics of their clientele and creating new programs to meet the language and cultural backgrounds of the clients. To contextualize these organizational efforts, an analysis of how policy changes (macro-level acculturation) interact with organizational practice is presented. Finally, the meaning of acculturation for the host society is discussed.

Explicitly or implicitly, comparative politics and migration policy theories suggest a 'regime effect' that links specific dynamics of immigration policy to liberal democracy. The literature's dominant focus on so-called 'Western liberal democracies', however, has left the 'regime effect' largely untested and research on variations and similarities in immigration policymaking across political systems strikingly undertheorized. This paper challenges the theoretical usefulness of essentialist, dichotomous categories such as Western/non-Western or democratic/autocratic and calls for a more nuanced theorizing of immigration policy-making. It proposes a two-dimensional classification of immigration policy theories, distinguishing between 'issue-specific' theories that capture immigration policy processes regardless of the political system in place and 'regime-specific' theories whose insights are tied to the characteristics of a political system. The paper also advances the 'illiberal paradox' hypothesis to explain why illiberal, autocratic states may enact liberal immigration policies. This theoretical expansion beyond the 'Western' and 'liberal' bubble is illustrated by an analysis of immigration policy-making in 21st century Morocco and Tunisia. Showing how domestic and international institutions, interests, and ideas shape immigration policy-making in Morocco's monarchy and Tunisia's democratic transition, the paper investigates the broader role of political systems in immigration politics and herewith seeks to contribute to a more general and global theorization of immigration policies.

  11. Contradictions and dilemmas within the practice of immigration medicine.

    To identify, explore and critique features of how practices associated with immigration medicine are socially organized. Specifically, how the work of designated medical practitioners (DMP) - physicians who conduct immigration medical examinations of prospective immigrants to Canada as contractors to the Canadian government department of Citizenship and Immigration Canada - is organized to occur in interactions with applicants who are diagnosed with the human immunodeficiency virus during the immigration medical examination. Findings from a theoretically informed empirical study using institutional and political activist ethnography inform this article. Data collection and analytic activities spanning 18 months included observational work in institutional settings, textual review, 61 interviews, and 2 focus groups in three Canadian cities. The medical examination of prospective immigrants to Canada is not organized as a therapeutic relation of care and has little to do with medicine per se. The rationale structuring the work of DMPs is actually administrative responsibilities. The work achieved by the DMP positions her/him as a key figure and important decision-maker within the Canadian immigration system. The work of doctors who practice immigration medicine gives rise to contradictions and ethical problems. These are largely unresolvable because of the way in which the labour process in which the DMP is implicated is coordinated. The social organization of immigration doctoring practices has serious consequences for prospective immigrants to Canada, for doctors themselves, and for the Canadian immigration system more broadly.

    The aim of this study is to identify the prevalence of cardiovascular disease (CVD) and major CVD risk factors, including diabetes, hypertension, dyslipidemia, obesity and smoking among Chinese immigrants by a systematic review of studies from various countries. PubMed and the China National Knowledge Infrastructure databases were searched for studies of the prevalence of major CVDs and risk factors, and of CVD mortality among Chinese immigrants. The search identified 386 papers, 16 of which met the inclusion criteria for this review. In mainland China, there is a pattern of high stroke prevalence but low coronary heart disease (CHD) prevalence. Among Chinese immigrants, there is a much lower prevalence and mortality of stroke, but a higher prevalence and mortality of CHD, even though these are lower than the rates in immigrants of other ethnicities in the host country. The prevalence of CVD risk factors is also markedly different in immigrants. Compared with mainland Chinese, Chinese immigrants have a higher prevalence of diabetes and hypertension, higher serum cholesterol, poorer dietary patterns, and higher prevalence of obesity and smoking. Thus, the epidemiological pattern of CVD among Chinese immigrants changes compared with resident mainland Chinese. The less healthy environmental factor after immigration may be a major trigger in the adverse CVD status of Chinese immigrants. It is important for policy-makers to pay more attention to specific minority immigrant groups, and to implement more effective preventive measures to improve the health of immigrant populations.

  13. The Liberalization of Canadian Immigration Policy (1945-1976

    Full Text Available Immigration policy has played a key role in Canadian history since the second half of 19th century. Certainly, immigration legislation was a major element of it. Some of the most important reforms in Canadian immigration policy took place in the first decades after the Second World War. This was a time of multiple legislative reforms conducted by the Canadian government, but in general, the immigration regulations introduced during that period started the process of liberalization in this area. The Immigration Act of 1976 played a key role in building up the new liberal strategy of Canadian immigration. The pre-reform period is also important because it helps to understand the evolution process from discrimi¬native legislation to liberal policy. Therefore, the focus of this study is on the development of Canadian immigration policy from 1945 to 1976. The present research examines the main preconditions for the adoption of the 1976 Immigration Act. It analyses legislation regulations, which paved the ground for post-war Canadian immigration policy, with a particular emphasis on regula-tions enacted from 1945 to 1976. This article provides an overview of Canadian immigration policy in post-war period. It also identifies successive documents that proved particularly influential for Canadian immigration policy at the time. The findings of this research point to a variety of causes for the legislation changes, from foreign and domestic policy to economy policy.

  14. Fractional Regularization Term for Variational Image Registration

    Full Text Available Image registration is a widely used task of image analysis with applications in many fields. Its classical formulation and current improvements are given in the spatial domain. In this paper a regularization term based on fractional order derivatives is formulated. This term is defined and implemented in the frequency domain by translating the energy functional into the frequency domain and obtaining the Euler-Lagrange equations which minimize it. The new regularization term leads to a simple formulation and design, being applicable to higher dimensions by using the corresponding multidimensional Fourier transform. The proposed regularization term allows for a real gradual transition from a diffusion registration to a curvature registration which is best suited to some applications and it is not possible in the spatial domain. Results with 3D actual images show the validity of this approach.

  15. Regular non-twisting S-branes

    2004-01-01

    We construct a family of time and angular dependent, regular S-brane solutions which corresponds to a simple analytical continuation of the Zipoy-Voorhees 4-dimensional vacuum spacetime. The solutions are asymptotically flat and turn out to be free of singularities without requiring a twist in space. They can be considered as the simplest non-singular generalization of the singular S0-brane solution. We analyze the properties of a representative of this family of solutions and show that it resembles to some extent the asymptotic properties of the regular Kerr S-brane. The R-symmetry corresponds, however, to the general lorentzian symmetry. Several generalizations of this regular solution are derived which include a charged S-brane and an additional dilatonic field. (author)

    Full Text Available We propose a novel online manifold regularization framework based on the notion of duality in constrained optimization. The Fenchel conjugate of hinge functions is a key to transfer manifold regularization from offline to online in this paper. Our algorithms are derived by gradient ascent in the dual function. For practical purpose, we propose two buffering strategies and two sparse approximations to reduce the computational complexity. Detailed experiments verify the utility of our approaches. An important conclusion is that our online MR algorithms can handle the settings where the target hypothesis is not fixed but drifts with the sequence of examples. We also recap and draw connections to earlier works. This paper paves a way to the design and analysis of online manifold regularization algorithms.

  17. Need for cognition and attitudes toward immigrants among russian students

    2011-04-01

    Full Text Available The author examined how need for cognition may contribute to the attitudes toward immigrants among Russian students. It was shown that although need for cognition may not correlate with attitude toward immigrants directly it might either interact with other factors or influence several relations of attitudes. Specifically, low need for cognition may facilitate the application of immigrants' ethnicity as a cue for the attitudes toward immigrants. On the contrary, those participants having highneed for cognition probably may not use immigrants ethnicity as a cue for attitudes. Additionally, need for cognition might make attitudes toward immigrants more positive among Russian women comparing with Russian men. Furthermore, a positive correlation between perceived stereotypicity and attitude toward immigrants was eliminated among lowneed for cognition participants. Moreover, this correlation has become even negative among lowneed for cognition males. The results of the study are discussed.

  18. More than culture: structural racism, intersectionality theory, and immigrant health.

    2012-12-01

    Explanations for immigrant health outcomes often invoke culture through the use of the concept of acculturation. The over reliance on cultural explanations for immigrant health outcomes has been the topic of growing debate, with the critics' main concern being that such explanations obscure the impact of structural factors on immigrant health disparities. In this paper, we highlight the shortcomings of cultural explanations as currently employed in the health literature, and argue for a shift from individual culture-based frameworks, to perspectives that address how multiple dimensions of inequality intersect to impact health outcomes. Based on our review of the literature, we suggest specific lines of inquiry regarding immigrants' experiences with day-to-day discrimination, as well as on the roles that place and immigration policies play in shaping immigrant health outcomes. The paper concludes with suggestions for integrating intersectionality theory in future research on immigrant health. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Immigration impacts the economy in ample ways: it affects growth, wages and total factor productivity. This study deals with the effects of immigration on firm exports. Can firms benefit from hiring immigrants to expand their export sales? Or do immigrants who live in the firm’s region affect trade...... evidence on the adjustment of firms’ product portfolio in response to immigration. Our results show that firms can reap the benefits from immigration only through hiring foreigners. This implies that the trade-cost reducing intercultural knowledge embedded in foreign expatriates can only be accessed via...... employment. Thus, to tap the full potential of foreign labor movements for international trade, political efforts should be targeted towards labor market integration of immigrants....

  20. Transition to Motherhood as an Immigrant: Risks and Obstacles

    Full Text Available The process of transition to motherhood that brings along a number of vital changes may be full of risks and difficulties for immigrant mothers. Poverty, being unfamiliar with the language of the country that the mother migrated, inability of healthcare policies in covering healthcare expenses of immigrants, insufficiency of social assistance and loneliness may negatively affect health of mother and infant. Postpartum immigrant mothers are seen depression, anxiety, stress and social isolation because of these obstacles. Therefore, health care professionals, who provide care to immigrant mothers, should clarify immigrant mothers' religious, cultural beliefs and attitudes. Procurement of peer support is important by developing care programs special to immigrant mothers and ensuring immigrant women to come together. Increase in the number of translators in hospitals and prepara-tion of education materials in native language of mothers will improve the level of benefiting from healthcare services.

    Tuberculosis (TB) screening in migrant children, including immigrants, refugees and asylum seekers, is an ongoing challenge in low TB incidence countries. Many children from high TB incidence countries harbor latent TB infection (LTBI), and some have active TB disease at the point of immigration into host nations. Young children who harbor LTBI have a high risk of progression to TB disease and are at a higher risk than adults of developing disseminated severe forms of TB with significant morbidity and mortality. Many countries have developed immigration TB screening programs to suit the needs of adults, but have not focused much attention on migrant children. To compare the TB immigration medical examination requirements in children in selected countries with high immigration and low TB incidence rates. Descriptive study of TB immigration screening programs for systematically selected countries. Of 18 eligible countries, 16 responded to the written survey and telephone interview. No two countries had the same approach to TB screening among migrant children. The optimal evidenced-based manner in which to screen migrant children requires further research.

    Given the increasing numbers of immigrant families in Canada, it is imperative that healthcare providers (HCPs) understand the caregiving experiences of immigrant family caregivers. Our study aimed to explore any special challenges faced by immigrant parents of children with cancer and to identify supportive factors. A constructivist grounded theory approach was used. Participants included 50 first generation Chinese and South Asian parents of children with cancer who were at least six months post-diagnosis. Recruitment took place at six Canadian pediatric oncology centres. Interviews were conducted in English, Cantonese, Mandarin, Urdu, Punjabi or Hindi. Analysis involved coding and the use of the constant comparison method. Interviewing continued until no new themes emerged. While immigrant parents described many challenges faced by any parent of a child with cancer, the context of being an immigrant made certain experiences particularly challenging. Parents described challenges in the following areas: managing caregiving demand and financial strain, accessing support from others, and interfacing with the healthcare system. Parents described receiving a range of practical, emotional, social and informational support from extended family, their workplace, other cancer families, community organizations and HCPs. Our study addresses an important gap in the research literature by providing practical insight into the experiences of immigrant family caregivers. Our findings may help to inform the development of pediatric oncology policies and programs in ways that respond to the unique needs and challenges of culturally and linguistically diverse families.

    2014-07-01

    Although recent research on crime and violence among immigrants suggests a paradox--where immigrants are more socially disadvantaged yet less likely to commit crime--previous research is limited by issues of generalizability and assessment of the full depth of antisocial behavior. We surmount these limitations using data from waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and compare immigrants (N = 7,320) from Asia, Africa, Europe, and Latin America to native-born Americans (N = 34,622) with respect to violent and nonviolent forms of antisocial behavior. After controlling for an extensive array of confounds, results indicate that immigrants are significantly less antisocial despite being more likely to have lower levels of income, less education, and reside in urban areas. These findings hold for immigrants from major regions of the world including Africa, Asia, Europe, and Latin America. This study confirms and extends prior research on crime and antisocial behavior, but suggests that it is premature however to think of immigrants as a policy intervention for treating high crime areas.

  5. Immigrants and the City: The Relevance of Immigration on Housing Price Gradient

    Full Text Available Foreign citizens are a more and more significant part of the population of Italian cities and society (8% of the country’s total population, and they contribute to changes in the cultural, social, and economic structure of the country. Our aim was to assess the incidence of the immigrant population on urban house price polarization, as measured using an original indicator: the center-periphery housing price gradient. While there is ample literature on the relationship between average prices and immigrant populations, less research has been conducted on immigration and the housing price gradient on a national scale. This price gradient may indicate whether immigration contributes to changing the residential market, also possibly revealing segregation phenomena. We ran multivariate regressions in several steps on an original dataset of housing prices and socio-economic factors concerning 112 Italian provincial capitals to elucidate whether immigration is correlated with the housing market divide. Our main findings confirmed that larger immigrant populations coincide with steeper housing price gradients on a national scale. Our tests also demonstrated that the relevance of this phenomenon varies for different urban forms, confirming related to housing price dynamics between the cities of northern and southern Italy the relevance of urban density in elucidating.

    We examined financial capability and asset ownership among low-income older Asian immigrants with special attention given to later-age immigrants who came to the United States when they were 55 years old or older. Survey data collected from supported employment program participants (N = 150) were used. The analyses demonstrated a low level of financial knowledge and asset ownership in the sample. The findings also indicated that later-age immigrants' financial-management skills, knowledge of social programs, and asset ownership were significantly lower than those of young-age immigrants. These findings call for active interventions to enhance economic security among low-income older Asian immigrants.

    2008-01-01

    More than 200 of the documented zoonoses represent a high proportion of the infectious diseases that cause cases of morbidity and mortality and almost 75% are emerging infections. Immigration and tourism are human activities that are included in the broader field of human migration and travel. Travel plays a significant role in the emergence and spread of disease. The migration of humans has provided the route of spread for infectious diseases and zoonoses (for example, plague, yellow fever, monkey pox and severe acute respiratory syndrome). Tourism constitutes a small fraction of overall movements of humans but a point worthy of note is the number of international travellers has increased by more than 1 300% over the last 50 years. In addition, over 80 million people, mostly from developing countries, are legal or illegal immigrants. The consequences of travel extend beyond the traveller to the population visited and the ecosystem. Tourism and immigration may constitute an interface for mixing different genetic and ecological profiles, as well as cultural and social aspects, which is of particular interest in regard to zoonoses. Primary prevention, epidemiological surveillance and health education in the framework of intersectoral and international collaboration remain the cornerstone for response to and control of zoonoses in the context of tourism and immigration.

    Full Text Available In the contemporary world the intensity of the immigration movements is constantly increasing. Countries which experience great immigrant flows are facing numerous problems which should be solved. The article studies the current immigration flows in EU countries, the United States of America and Canada and presents three main models of integration policy towards immigrants – political assimilation, functional integration and multicultural model. Separate models are distinguished for the Muslims’ integration. The author examines the peculiarities of every model and examines the conclusions provided by the Migrant Integration Policy Index (MIPEX concerning the situation of the immigrants’ integration in 31 countries in 2011. Among all the policy indicators the first that are defined are as follows: political participation, education, labour market mobility and anti-discrimination. The situation with immigrants’ integration in Ukraine is also studied as it is gaining a great attention of the authorities and the public. The measures and practical steps done regarding this situation in Ukraine in recent years are analyzed using the information offered by the State Migration Service of Ukraine.

    2017-07-19

    Economic immigrants generally, and economic class principal applicants (ECPAs) specifically, tend to have better health than other immigrants. However, health outcomes vary among subcategories within this group, especially by sex. This study examines hospitalization rates among ECPAs aged 25 to 74 who arrived in Canada between 1980 and 2006 as skilled workers, business immigrants, or live-in caregivers. The analysis used two linked databases to estimate age-standardized hospitalization rates (ASHRs) overall and for leading causes by sex. ASHRs of ECPA subcategories were compared with each other and with those of the Canadian-born population. Logistic regression was used to derive odds ratios for hospitalization among ECPAs, by sex. Male and female ECPAs aged 25 to 74 had significantly lower all-cause ASHRs than did the Canadian-born population in the same age range. This pattern prevailed for each ECPA subcategory and for each disease examined. Compared with skilled workers, business immigrants had lower odds of hospitalization; live-in caregivers who arrived after 1992 had higher odds. Adjustment for education, official language proficiency, and world region reduced the strength of or eliminated these associations. Compared with the Canadian-born population, ECPAs generally had low hospitalization rates. Differences were apparent among ECPA subcategories.

    As a consequence of the accelerated globalization process, today major cities all over the world are characterized by an increasing multiculturalism. The integration of immigrant communities may be affected by social polarization and spatial segregation. How are these dynamics evolving over time? To what extent the different policies launched to tackle these problems are working? These are critical questions traditionally addressed by studies based on surveys and census data. Such sources are safe to avoid spurious biases, but the data collection becomes an intensive and rather expensive work. Here, we conduct a comprehensive study on immigrant integration in 53 world cities by introducing an innovative approach: an analysis of the spatio-temporal communication patterns of immigrant and local communities based on language detection in Twitter and on novel metrics of spatial integration. We quantify the Power of Integration of cities –their capacity to spatially integrate diverse cultures– and characterize the relations between different cultures when acting as hosts or immigrants.
