    This article focuses on two dimensions of labour market integration, sorting into different industries (niching) and sorting into workplace establishments (segregation) by share of migrant workers. We seek to understand to what degree these two dimensions of immigrants' lack of labour market integration - niching and segregation - overlap with each other. The study is based on Finnish individual, panel and relational registry data, and we focus on the three largest immigrant groups - Estonians, Russians and Swedes - who have arrived from countries with different wealth levels to the Helsinki metropolitan area. By applying generalised structural equation modelling, we estimate industrial niching and workplace segregation - measured as a degree of overconcentration of immigrants in particular industries and workplace establishments, respectively - jointly. Our main findings show a strong overlap between niching and segregation for all ethnic groups. Segregation and niching levels are the highest among Estonians, but very similar for Russians and Swedes. These findings do not support the cultural similarity argument in immigrant labour market integration. Rather, immigration policy and origin country wealth level may be determinant. Additionally, we found that females are more likely than males to be employed simultaneously in niched industries and segregated workplace establishments, supporting the thesis of gender-based networks

    A new method is suggested herein for the synthesis of tetrasubstituted glycolurils by treatment of disubstituted glycolurils (di-tert-butylglycolurils, di-isopropylglycoluril) with alkylating agents such as methyl iodide, ethyl bromide and benzyl chloride in acetonitrile in the presence of KOH. Optimum conditions for the preparation of the target product in high yield were studied by the example of the synthesis of dibenzyl-di-tert-butylglycoluril: time 3 h and reaction temperature 75ºС at a 1:4 M/M molar ratio of disubstituted glycoluril to benzyl chloride. Thus, the target product yield was 83%. It was also found that benzyl chloride should be used as the alkylating agent because the product yield under the same equal conditions was higher with benzyl chloride than with benzyl bromide which in turn is more toxic and less availableПредложен новый способ получения тетразамещенных гликольурилов, заключающийся в обработке дизамещенных гликольурилов (дитрет-бутилгликольурила, диизопропилгликольурила) алкилирующими агентами: йодистый метил, бромистый этил и хлористый бензил в среде ацетонитрила в присутствии основания КОН. На примере получения дибензил-дитрет-бутилгликольурила изучены оптимальные условия для получения продукта с высоким выходом: продолжительность 3 ч и температура реакции 75 ºС при мольном соотношении дизамещенного гликольурила к бензил хлориду 1:4 моль/моль. Таким образом, выход целевого продукта составил 83 %. Также установлено, что в качестве алкилирующего агента следует использовать хлористый бензил в связи с тем, что выход продукта в одних и тех же условиях выше, чем при использовании бромистого бензила, который, в свою очередь, является наиболее токсичным и менее доступны

    The impact of new affective components on museum visitor retention: the context of major city event using SEM and CTree

    Get PDF
    Purpose The main purpose of this study is to examine the relationship between ranges of affective components that have an impact on the revisit intention of museum visitors, in the context of a major city event. The study reveals the most significant factors that affect decision-making by applying the findings to a structural equation modelling (SEM) and conditional inference tree (CTree). Design/methodology/approach The paper utilises face-to-face survey research at the “Long Night of Museums” event in Saint Petersburg, 298 questionnaires were completed on the night of the event. The empirical part of the research is based on the SEM and interpreted by using the CTree. The SEM model measures the direct and indirect influence of the cognitive and affective components; the CTree enables the testing of both component and the joint effect they both produce. Findings This study shows a strong indirect correlation between the cognitive component of the major city event and the revisit intention of museum visitors. When focussing on affective components, both the SEM and the CTree demonstrated that attractiveness and atmosphere are revealed to be the most impactful elements regarding visitor retention and repeat custom. The research allows for a deeper understanding of visitor behaviours, intentions and their decision-making processes. Practical implications The results of the study allow museum managers to understand how to create repeat custom amongst visitors, by appreciating the importance of participation in major city events and the role that attraction and atmosphere play when creating intention for repeat visit. The research has uncovered which dimensions are the most important to visitors, and as a result, these particular dimensions should be thoroughly developed by museums in future in order to attract and repeat visits. This study has demonstrated the practical implications for museums participating in city events. When considering policy makers, this particular research provides an opportunity to develop recommendations for future city events, as well as using the CTree to assess and predict the effectiveness of visitor behaviour. Originality/value This is an original study which aims to integrate the impact of the perceived value of the cognitive component and a new range of affective elements regarding museum retention in the context of a major city event. The study includes newly developed dimensions of perceived value, as well as a unique focus on affective dimensions such as – atmosphere and attraction. Another point of originality is provided by using a CTree, which captures an in depth understanding of the intention formation process. This study provides an opportunity to advance our understanding of visitor decision-making processes

    Abstract:  This article focuses on two dimensions of labour market integration, sorting into different industries (niching) and sorting into workplace establishments (segregation) by share of migrant workers. We seek to understand to what degree these two dimensions of immigrants’ lack of labour market integration—niching and segregation—overlap with each other. The study is based on Finnish individual, panel and relational registry data, and we focus on the three largest immigrant groups—Estonians, Russians and Swedes—who have arrived from countries with different wealth levels to the Helsinki metropolitan area. By applying generalised structural equation modelling, we estimate industrial niching and workplace segregation—measured as a degree of overconcentration of immigrants in particular industries and workplace establishments, respectively—jointly. Our main findings show a strong overlap between niching and segregation for all ethnic groups. Segregation and niching levels are the highest among Estonians, but very similar for Russians and Swedes. These findings do not support the cultural similarity argument in immigrant labour market integration. Rather, immigration policy and origin country wealth level may be determinant. Additionally, we found that females are more likely than males to be employed simultaneously in niched industries and segregated workplace establishments, supporting the thesis of gender-based networks.Keywords:  country of origin wealth level; immigration; labour market; niching; segregation</p

    The Motherland of the Giant Hogweed

    No full text
    Human intervention in ecosystems has led to the accelerated dissemination of species deemed ‘invasive’, often accompanied by a perception of inherent malevolence. In Russia, the rampant spread of the giant hogweed has emerged as one of the most debated ecological issues in recent decades. The giant hogweed (Heracleum), a herbaceous monocarpic plant first discovered in the Caucasus in 1944, now proliferates throughout the country, from Sochi to Yamal and from the Arctic to downtown Moscow. It is estimated that the giant hogweed occupies over 10% of continental Europe within Russia, with projections suggesting an increase to nearly 100% within the next 30 years. Frequently, the plant is likened to a botanical emblem of Russia or a symbol of Putin's regime, reflecting the social tensions that oscillate between apathy and antipathy toward the hogweed in media and activism spheres

    Mapping the Scope of China’s Soft Power in Estonia

    This article examines China’s soft power in Estonia since the launch of the Belt and Road Initiative in 2013. Findings have suggested that while Beijing’s domestic political values do not inform its projection of soft power, the Estonian government and general public perceive China mainly through the prism of its state-centric governance model and consequently view most of China’s deployment of supposedly “soft” power as sharp

    Influence of Schumann Range Electromagnetic Fields on Components of Plant Redox Metabolism in Wheat and Peas

    The Schumann Resonances (ScR) are Extremely Low Frequency (ELF) electromagnetic resonances in the Earth-ionosphere cavity excited by global lightning discharges. ScR are the part of electromagnetic field (EMF) of Earth. The influence of ScR on biological systems is still insufficiently understood. The purpose of the study is to characterize the possible role of the plant cell redox metabolism regulating system in the Schumann Resonances EMF perception. Activity of catalase and superoxide dismutase, their isoenzyme structure, content of malondialdehyde, composition of polar lipids in leaf extracts of wheat and pea plants treated with short-time (30 min) and long-time (18 days) ELF EMF with a frequency of 7.8 Hz, 14.3 Hz, 20.8 Hz have been investigated. Short-time exposure ELF EMF caused more pronounced bio effects than long-time exposure. Wheat catalase turned out to be the most sensitive parameter to magnetic fields. It is assumed that the change in the activity of wheat catalase after a short-term ELF EMF may be associated with the ability of this enzyme to perceive the action of a weak EMF through calcium calmodulin and/or cryptochromic signaling systems

    Income Inequality and Residential Segregation in European Cities

    Get PDF
    Based on extensive research with distinguished scholars within the book project ‘Socioeconomic Segregation in European Capital Cities’, this chapter summarizes the key trends in income inequality and socioeconomic segregation in Europe. We draw our data from the two last census rounds, and we focus on the most common indicators of income inequality (Gini Index) and residential segregation (Dissimilarity Index). We find that levels of residential segregation grew between the two last censuses in most of the cities included in our study. Changes in residential segregation follow changes in income inequality with a time lag, and it tends to happen in both directions. Low levels of income inequality relate to low levels of segregation after 10 years, and high levels of inequality relate to high levels of segregation after 10 years.Urbanis
