This study focuses on earnings disadvantages experienced by three ethnic groups of Jewish immigrants in Israel. Data were obtained from the 2011 Income Survey gathered by the Israel Central Bureau of Statistics. The findings reveal that when compared to Israeli-born, all ethnic groups are disadvantaged in earnings attainment in the first generation. The earnings disadvantages of immigrants as compared to Israeli-born decrease with the passage of time and become negligible in the second generation. To disentangle the impact on earnings penalty of ethnic origin from that of immigrant status, a procedure for decomposing mean differences between groups is introduced. The analysis reveals that earnings disadvantage among Ashkenazim and Soviet immigrants can be attributed to immigrant status but not to ethnicity. By contrast, earnings penalties among Sephardim immigrants can be attributed to both ethnicity and immigrant status. The implications of the long-lasting effect of ethnicity versus the short-term effect of immigrant status are discussed.  相似文献

This study of immigrants’ integration in Israel centers on one major subjective parameter, namely the immigrant's identity. To explain it we explore a series of possible factors: demographic variables, economic status, and human and social capital characteristics. Three recent immigrant groups are examined: from Western countries, from the former Soviet Union (FSU), and from Ethiopia. These immigrants came to Israel during the last two decades from different societies, following different immigration circumstances and various motives.

The findings, based on the 2007 Ruppin survey data, point to the significant impact of the identity as perceived by veteran Israelis on the immigrants’ self-identity for the three groups under study. Also, different variables affect each of the immigrant groups. FSU immigrants behaved according to most of our hypotheses, whereas Western and Ethiopian immigrants did not. Findings are discussed in light of the debate on measuring and defining immigrants’ identity.  相似文献

Although many scholars point to the importance of gender in structuring the immigrant experience, many immigrant women themselves do not attribute much importance to the role that gender plays in their lives. To explore this issue further, we investigate how thirty-two foreign-born Latinas define their experiences in Utah, a new immigrant destination that has received little empirical attention. The women in our sample indicated five major challenges they faced in their everyday lives: social isolation, language difficulty, racial-ethnic prejudice, poverty and lack of documentation. Most of the women described these challenges in terms of social class, race-ethnicity and immigrant status, rather than gender. We argue that migration research needs to be more attuned to axes of oppression other than gender and more attentive to how immigrant women, themselves, interpret their everyday lives.  相似文献

The golden jackal and red fox are among the wildlife species protected by Israeli law as enforced by the Israel Nature and Parks Authority. In 1964, as a part of a management program to control rabies in Israel, a poison eradication campaign was launched to exterminate golden jackals, considered to be the main reservoir of the disease. The program resulted in the near-complete extermination of jackals in Israel, while foxes were only mildly affected. Jackals have since regained their original numbers and have recolonized southern Israel. We here examined the population structure of the golden jackal and red fox in Israel, 48 years after the poison eradication campaign. DNA from 88 golden jackals and 89 red foxes representing five different geographic regions was extracted and amplified at 13 microsatellite loci in order to characterize the populations on a genetic level. High genetic diversity was found among the jackal and fox populations. A possible migration route through the Jordan Rift Valley was suggested for both species by the genetic similarity of populations in northern and southern Israel. However, in both species, the animals from the center of Israel were distinctive from those north or south, indicating the relative isolation of central populations, likely due to fragmentation or a high abundance of food resources. Genetic profiles obtained for the golden jackal and the red fox in Israel may aid in their conservation management and in the study of zoonotic diseases.  相似文献

Neighbourhoods are important contexts for the socialization and adaptation of immigrant youth. They provide resources and opportunities for positive interactions with peers and non-family adults. But neighbourhoods differ systemically in their demographic composition and the type and quality of resources they offer young people. In the US, there is an implicit assumption equating suburban neighbourhoods with better schools, more jobs and higher quality housing compared to urban neighbourhoods. There is however, little explicit empirical evidence of how such differences may shape the experience of immigrant youth. This gap is concerning in light of recent trends of immigrants to move directly to the suburbs. The first part of the paper reviews the literatures on immigrant adaptation and neighbourhood effects. Drawing on two qualitative studies, the second part of the paper illustrates mechanisms through which suburban and urban neighbourhoods may influence the socialization and adaptation of immigrant youth growing up in them.  相似文献

粘虫迁出与迁入种群的行为和生理特性比较   总被引:4,自引:1,他引:3  
系统比较了田间粘虫Mythimnaseparata (Walker)迁出与迁入种群在飞行能力、 飞行肌干重、卵巢发育、交配以及保幼激素滴度等指标的差异。结果显示,迁出种群的飞行潜 力显著强于迁入种群,雌蛾中胸背纵肌平均干重(6.53 mg)也显著高于迁入种群(5.92 mg ),但卵巢发育程度显著低于迁入种群;迁出种群的交配率和平均交配次数均显著低于迁入种 群;早期迁入的雌蛾卵巢发育级别和交配率相对较低,并随迁入时间的延长而增加。迁出与迁入 种群雌蛾的保幼激素滴度也存在显著差异,两者的JHⅡ滴度平均分别为4.63 ng/mg和8.69 ng/mg。这些结果说明,粘虫迁飞前后的行为、生理和生殖特性具有明显的变化,迁出种群具有较强的飞行潜力,生殖系统的发育受到暂时性抑制;而迁入种群飞行能力下降,卵巢发育级别 较高,交配率增加。同一世代早期迁入的雌蛾卵巢发育程度较低,表明粘虫迁飞是发生在成虫 发育的初期,迁飞过程中卵巢发育受到暂时性抑制,迁入以后便迅速发育并开始繁殖。粘虫迁 飞的行为和生理特性与“卵子发生 飞行拮抗综合症候(oogenesisi flight syndrome)”相符 。内分泌激素(保幼激素)在其迁飞与生殖的转换过程中起着重要的调控作用。  相似文献

The platelet aggregation activity was studied in 79 healthy subjects, immigrant and indigenous, aged between 20 and 59 years, living in the Yamalo-Nenets Autonomous Area. The platelet count and spontaneous and induced platelet aggregation were assessed using the inducer adenosine diphosphate (ADP). It was established that the spontaneous platelet aggregation rate was higher (p < 0.01) in indigenous residents of the region than in the immigrant population, and the ADP-induced platelet aggregation values were higher in the immigrant population of the Far North (p < 0.01).  相似文献

BackgroundPrevalence of psychological distress (i.e. depressive and anxiety symptoms) in medically ill patients is high. Research in the general population shows a higher prevalence of psychological distress among immigrants compared to natives. Our aim was to examine the prevalence of psychological distress in the hospital setting comparing immigrant and native Dutch patients and first and second generation immigrant patients.MethodsPrevalence of psychological distress was assessed using the extended Kessler-10 (EK-10) in 904 patients in a Dutch general teaching hospital. Logistic regression was used to calculate odds ratios to determine differences between native and immigrant patients and first and second generation immigrants in the prevalence of psychological distress. We adjusted for demographic and social variables, socio-economic status, physical quality of life, history of psychiatric disease and health care use.ResultsOf 904 patients, 585 were native Dutch patients and 319 were immigrant patients. The prevalence of psychological distress in native compared to immigrant patients was 54% and 66% respectively, with especially high prevalences among Turkish and Moroccan immigrant patients. The crude OR for prevalence of psychological distress for immigrant patients versus native patients was 1.7 (95% CI 1.2–2.2) and for first versus second generation immigrant patients 2.1 (95% CI 1.2–3.5). After full adjustment ORs were 1.7 (95% CI 1.2–2.3) and 2.2 (95% CI 1.2–4.1) respectively.ConclusionImmigrant patients and first generation immigrant patients were more likely to have psychological distress compared to native patients and second generation immigrant patients respectively. We found a particularly high prevalence of psychological distress in Turkish and Moroccan immigrants.  相似文献

The clutch sizes of the passerines of Israel and the Cape Province, South Africa, which lie at similar latitudinal range, were compared. Mean clutch sizes in Israel and the Cape Province are 4.09 and 2.87, respectively. Mean clutch size of Israeli migrants is larger than that of residents (4.45 and 3.93, respectively), but no such difference exists in the Cape Province.
It is suggested that the larger clutch size in Israel is a result of two factors: (1) the higher proportion of wintering birds in Israel in comparison with the Cape Province and the presence of many transients there which may compete with resident birds and cause high winter mortality among them and (2) a higher proportion of migrants in the Israel avifauna, which suffer heavy losses during their trans-Saharan migration in comparison with Cape Province migrants, which travel shorter routes. The resulting reduced competition for food during the breeding season in Israel enables passerines there to lay larger clutches as predicted by Ashmole (1963) and Ricklefs (1980).  相似文献

为了解迁飞种群与居留种群后代发生再猖獗的生理生化差异,探讨再猖獗的机制,比较研究了在两个水稻品种(TN1和协优963)上施用杀虫剂后褐飞虱Nilaparvata lugens (Stål)迁飞虫和本地虫后代3龄、5龄若虫和成虫体内可溶性糖和粗脂肪含量以及迁飞成虫与其后代成虫体内游离氨基酸含量的变化。结果表明: 施药以及未施药处理(对照)TN1水稻品种上的迁飞后代3龄、5龄若虫和成虫体内的可溶性糖含量均显著高于本地虫。与可溶性糖含量相比,施药以及对照TN1水稻品种上的迁飞后代3龄、5龄若虫和成虫体内的粗脂肪含量均显著低于本地虫。协优963上3龄、5龄若虫体内可溶性糖含量的变化趋势与TN1上相同。对照水稻上迁飞成虫的粗脂肪含量显著高于本地种群,迁飞与本地3龄、5龄若虫间粗脂肪含量没有显著差异。杀虫剂处理后的水稻上迁飞后代5龄若虫和成虫体内粗脂肪含量显著高于本地虫。方差分析结果也显示,可溶性糖和粗脂肪含量的变化在虫源和杀虫剂,虫源和杀虫剂浓度以及杀虫剂类型和浓度方面有显著交互作用。两种水稻品种上,迁飞当代成虫体内的游离氨基酸含量显著低于其后代成虫。在经3种杀虫剂处理后,TN1上施用三唑磷后成虫体内的氨基酸含量显著高于施用溴氰菊酯和吡虫啉的处理,而协优963上施用溴氰菊酯和吡虫啉显著高于施用三唑磷的处理。本研究结果对深入阐明农药诱导褐飞虱再猖獗的机制具有参考价值。  相似文献

The connection between ethnicity and democracy has been the subject of much debate among scholars in various disciplines. This article deals with the ethnic divisions and the debate over democracy in Israel. How Israel should be defined, with regard to the democracy-ethnic affiliation nexus, has long been debated by scholars in the field. Some present Israel as a consociational democracy. Some Israeli scholars consider Israel to be a liberal democracy. Others define it as an 'ethnic democracy' that balances the ethnic and democratic components in its dealings with its Arab-Palestinian citizen. In this article I claim that Israel, like many other countries (Romania, Slovakia, Estonia, Latvia, Canada until the sixties, Malaysia) is not a democracy, if our criterion is the ethnic preference it shows for Jews. It is, instead, a textbook example of an ethnic state, applying sophisticated policies of exclusion and discrimination towards the Arab minority. In principle, it invites its Arab citizens to participate in its life; but under no circumstances does it offer them equality. It maintains Jewish superiority in all fields and grants them preference symbolically, structurally and practically.  相似文献

Immigrant women are a particularly vulnerable part of the immigrant population. In this paper we analyse negative attitudes towards immigrant women in Norway. We focus on immigrant women’s formal job qualifications, their religious background and wearing of hijab – the headscarf sometimes used by Muslim women. Using survey-embedded experiments we are able to analyse the net effects on attitudes of job qualifications, Islamic religious background and the hijab. The results show that native population frequently has more negative views of Muslim women who wear a hijab. The negative effects of a hijab do not seem to be strongly reduced if a woman wearing it has higher education. With a single exception, the results also show that Muslim background in itself (i.e. without the hijab) does not have any strong effect on attitudes of the native population towards immigrant women.  相似文献

Multilocus microsatellite typing (MLMT) was used to investigate the genetic variation among 44 Israeli and Palestinian strains of L. infantum isolated from infected dogs and human cases to determine their population structure and to compare them with strains isolated from different European countries. Most of the Israeli and Palestinian strains had their own individual MLMT profiles; a few shared the same profile. A Bayesian model-based approach and phylogenetic reconstructions based on genetic distances inferred two main populations that were significantly different from the European strains: population A, containing 16 strains from places in the West Bank and 11 strains from central Israel; and population B, containing 7 strains from northern Israel, 9 from central Israel, and one Palestinian strain from the Jenin District. Geographically distributed sub-populations were detected within population B. These results demonstrate similar disease dynamics in Israel and the Palestinian Authority. The re-emergence of VL in the case of population A is more likely owing to increased dog and human contact with sylvatic cycles of parasitic infection rather than to recent introduction from the older foci of northern Israel. The latter scenario could be true for population B found in few foci of Central Israel.  相似文献

We continue our study of the effects of pollen and seed migration on the cytonuclear structure of mixed-mating plant populations by analyzing two deterministic continent-island models under the critical assumption of paternal cytoplasmic inheritance. The major results of this study that contrast with our previous conclusions based on maternal cytoplasmic inheritance are (i) pollen gene flow can significantly affect the cytonuclear structure of the island population, and in particular can help to generate cytonuclear disequilibria that greatly exceed the magnitude of those that would be produced by seed migration or mixed mating alone; (ii) with simultaneous pollen and seed migration, nonzero cytonuclear disequilibria will be maintained not only when there is disequilibrium in the immigrant pollen or seeds, but also through a variety of intermigrant admixture effects when the two pools of immigrants differ appropriately in their cytonuclear compositions; (iii) either immigrant pollen or immigrant seeds can generate disequilibria de novo in populations with initially random cytonuclear associations, but pollen migration alone generally produces lower levels of disequilibrium than does comparable seed migration, especially at high levels of self-fertilization when the overall fraction of immigrant pollen is low; (iv) the equilibrium state of the island population will be influenced by the rate of pollen gene flow whenever there is either allelic disequilibrium in the immigrant pollen or simultaneous seed migration coupled with different cytoplasmic or nuclear allele frequencies in immigrant pollen and seeds or nonzero allelic disequilibrium in either immigrant pool. The estimation of pollen migration should therefore be facilitated with paternal cytoplasmic inheritance relative to the case of maternal cytoplasmic inheritance. These basic conclusions hold whether the population is censused as seeds or as adults, but with simultaneous pollen and seed migration, the relationship between census time and the ability to detect nonrandom cytonuclear associations is complex. When migration is through pollen alone, however, the cytonuclear structure of the island population is independent of the life stage censused.  相似文献

After presenting demographic data to demonstrate why immigrant youth are and will be important, this article addresses the limited literature on immigrant youth civic engagement. It also examines the historical literature of immigrant youth in the United States, specifically that of the last great wave of immigration approximately 100 years ago, along with the literature on contemporary adult immigrant civic engagement. It concludes that today's immigrant youth are Americanizing. Nevertheless, when U.S. society and particularly the U.S. state treats immigrant youth as different, the immigrant youth respond with pride by defending their cultural integrity, their right to be different. Contemporary immigrant youth also have the opportunity to maintain transnational ties with their homeland. In response to these forces and opportunities, immigrant youth maintain multiple identities, sometimes identifying with their homeland culture at other times with the United States. The unanswered question is what difference these multiple ties may make for civic engagement.  相似文献

In the field of education and children of immigrants we are confronted with a peculiar clash of opinions. Some believe that the differences in school attainment between indigenous children and children of immigrant families can be explained in terms of social class. Others seek the differences in terms of status groups. Empirical research was carried out in one of the bigger cities of The Netherlands, which attempted to further this theoretical debate. The results indicate that the influence of an immigrant background on school attainment is largely mediated by both social class and status. Ethnicity, however, also has a specific effect on education, independent of social class and status. It is argued that the characteristic of ethnicity is a sociological kind of motivation. The educational motivation of immigrant families can have a ‘positive’ effect in the sense that ‘black’ schools perform reasonably well, and a ‘negative’ effect in the sense that immigrant children at schools with a high level of aspiration perform less well than their indigenous Dutch schoolmates.  相似文献

Fishes have been introduced worldwide with deleterious effects on various native ecosystems. To gain insight into this phenomenon in Israel, we studied the introduced ichthyofauna. There are 27 species of introduced fishes in the freshwater habitats of Israel, a large number for a nation this size. Ten of these species reproduce in the wild. Most of these fishes were introduced for aquaculture; some are constantly restocked. The proportion of restocked versus established species in Israel is high compared to other regions. New fish introductions continue in recent decades, unlike the global trend. In Israel these species are found in the Jordan Basin, Lake Kinneret (Sea of Galilee), and the coastal plain rivers. A few species are widespread, and most are found in Lake Kinneret. Harmful effects of introduced fishes have been suspected and in several cases demonstrated. We encourage further caution when new introductions are contemplated; in some regions eradication should be attempted.  相似文献
