Contextualising Chinese migration to Africa

Who are ‘the Chinese’ in Africa? Why are they there? As China’s engagement with African countries intensifies, and the size of the Chinese population in Africa increases, these questions have elicited substantial attention. Many attempts to provide answers, especially in the media and popular publications, are problematically based on uninformed stereotypes and undifferentiated notions of ‘the Chinese’, by implication a homogeneous group lacking contextualisation. Seeking to address such characterisations, this paper uses the digital communications of present and prospective Chinese migrants to provide a more nuanced picture of the motivations, preoccupations and migration experiences of private entrepreneurs and state-owned enterprise workers

Uitroeiing van schurft op varkensbedrijven

De Projectgroep “Vrijwaring Schurft” heeft van het Programmateam “Diergezondheid in Beweging” de opdracht gekregen om, indien mogelijk, een haalbaar en controleerbaar schurftvrij-programma voor de Nederlandse varkenshouderij te ontwikkelen. De volgende onderzoeksvragen zijn hierbij beantwoord: 1 - Is het mogelijk een ELISA te ontwikkelen voor het aantonen van antilichamen in het bloed tegen de schurftmijt van het varken (Sarcoptes scabiei var. suis), die op het laboratorium routinematig kan worden toegepast? 2- Is het mogelijk om met schurft besmette varkensbedrijven door middel van een tweemalige ivermectine-behandeling van alle aanwezige varkens, aangevuld met hygiënische maatregelen maar zonder ontschurfting van de omgeving, vrij te krijgen van schurft? 3 - Kan een bedrijf dat eenmaal schurftvrij is door middel van uitsluitend hygiënische maatregelen gedurende tenminste één jaar schurftvrij blijven? 4 - Wat is het ingeschatte economische effect van uitroeiing van schurft op praktijkbedrijven

Migration from China to the EU: the challenge within Europe

At the beginning of the 21st Century, we have witnessed a rapid growth in Chinese immigration to the European Union (EU), which has had a profound impact on local Chinese communities in various ways. This chapter aims to reveal the latest developments in Chinese immigration in the EU, as well as the new dynamics, features and impacts on local Chinese communities. The above questions are addressed by a combination of secondary data analysis and our own observation in Italy and the UK in recent years. Some challenging issues facing Chinese communities are highlighted

Sending Country Policies

This chapter explores the twin central questions of how and why countries of origin reach out to expatriate populations. It first outlines basic concepts and typologies related to sending country policies, focusing particularly on key countries of origin of migrants settled within the European Union. Second, the chapter reviews central explanations for the emergence of sending country policies. However, sending countries do not reach out to their emigrants in equal measure. Differences are therefore examined in the outreach policies of sending countries and in sending countries' transnational relations with diasporas. The last part of the chapter discusses the nexus between sending country policies and migrant integration in the country of residence. On the basis of existing research, the chapter argues that sending country policies may intersect with migrants' integration in a number of ways. For example, migrant sending countries may seek to strengthen the upward mobility of their expatriate citizens in their place of residence abroad, and they may call for greater protection of migrant workers in precarious labour situations. Little is currently known about how migrants and diasporas respond to these policies and how they are perceived by political actors of countries of residence. This is an area for further study. More analysis is also needed to determine the extent that sending country outreach policies aimed at bonding with and supporting citizens abroad challenge territorial policy sovereignty and the strength of receiving countries in agenda-setting in international cooperation on migration and migrant settlement

Substituting meat and the role of a situational context : exploring associations and motives of Dutch meat substitute-users

Purpose: The Dutch market for meat substitutes has grown steadily, however, their market share is still low, and meat consumption in the Netherlands is not decreasing. For a transition towards a more plant-based diet, understanding consumer motives regarding meat substitutes is important. The purpose of this study was to explore what motives lay behind the appropriateness of the use of meat substitutes in different usage situations. Design/methodology/approach: In total, 20 semi-structured in-depth interviews were performed to discover Dutch consumers’ associations with the terms “eating vegetarian” and “meat substitutes”, as well as motives regarding the situational appropriateness of meat substitutes. Findings: The most mentioned motives for eating vegetarian were “environmental impact”, “health” and “animal welfare”, while meat substitutes were mainly eaten to replace meat in the meal. Most participants perceived vegetarian stir-fry pieces appropriate for almost all situations; the appropriateness of other meat substitutes was more situation-specific. The thematic content analysis yielded seven categories for the motives given for the (in)appropriateness of the four meat substitutes in six usage situations: “Functionality”, “Convenience”, “Properties”, “Preferences”, “Association with meat”, “Association with meals” and “Nutrition”. Mainly motives in the categories convenience and functionality (function of the meat substitute in a meal) were mentioned for all situations and other motives were situation-specific. Originality/value: The focus in the development of plant-based foods is mostly on the product properties. The situational appropriateness and the underlying motives regarding meat substitutes have not yet been studied. This exploratory study suggests that these should be taken into consideration in the design of new meat substitutes

High-resolution fractionation after gas chromatography for Effect Directed Analysis.

This research presents an analytical technology for highly efficient, high-resolution, and high-yield fractionation of compounds after gas chromatography (GC) separations. The technology is straightforward, does not require sophisticated cold traps or adsorbent traps, and allows collecting large numbers of fractions during a GC run. The technology is based on direct infusion of a carrier solvent at the end of the GC column, where infusion takes place in the GC oven. Pentane and hexane used as carrier solvent showed good results. Acetonitrile also showed good results as a more polar carrier solvent. Development and optimization of the technology is described, followed by demonstration in a high-throughput effect directed analysis setting toward dioxin receptor bioactivity. The GC fractionation setup was capable of collecting fractions in the second range. As a result, fractionated compounds could be collected into one or two fractions when 6.5 s resolution fractionation was performed. Subsequently, mixtures containing polycyclic aromatic hydrocarbons, of which some are bioactive toward the dioxin receptor, were profiled with a mammalian gene reporter assay. After fractionation into 96-well plates, we used our new approach for direct cell seeding onto the fractions prior to assaying which allowed dioxin receptor bioactivity to be measured directly after fractionation. The current technology represents a great advance in effect directed analysis for environmental screening worldwide as it allows combining the preferred analytical separation technology for often non-polar environmental pollutants with environmentally relevant bioassays, in high resolution. © 2013 American Chemical Society
