Disentangling entangled mobilities: reflections on forms of knowledge production within migration studies
European migration studies have been criticised for having certain epistemological and theoretical underpinnings that reproduce hegemonic structures, especially the ânational order of thingsâ and colonial legacies. In this article, we propose the concept of âentangled mobilitiesâ to address some of these challenges. Entangled mobilities as a theoretical lens enables us to study specific global and transnational processes, the ways in which they are historically and locally situated, and how they materialise in individual mobilities of differently positioned actors within an unequal political global economy. This lens helps us simultaneously overcome nationality- and ethnicity-centred epistemologies, confront colonial aphasia, and be sensitive to the multiple inequalities and mobility regimes within which human mobilities evolve. Furthermore, the prism of entangled mobilities provides an ideal methodological departure point from which to systematically examine how human mobilities are intertwined and interdependent and to reveal how they are embedded in and shaped by asymmetric, historically evolved power structures. We propose three pragmatic entry points for mobilising the concept: in specific places, in terms of the intersections and interdependencies of different mobile people, and in the context of the biographical trajectories of individuals. Finally, we invite scholars from other fields, such as policy research, to innovatively adapt this approach to gain alternative knowledge and address inequalities
Informing for the sake of it: legal intricacies, acceleration and suspicion in the German and Swiss migration regimes
In migration law, being informed about legal and administrative procedures constitutes an essential procedural safeguard. Yet, in practice, the transparency of legal practices is often structurally undermined, resulting in the curtailment of procedural safeguards and potentially affecting perceptions of procedural justice. Building on our multi-sited ethnographic research in Germany and Switzerland, we first argue that migrants find it often difficult to anticipate how laws work, contradicting the key procedural law principle of legal certainty. Second, a general trend towards acceleration in migration administration allows limited time for information to reach migrants on the ground, leaving them uninformed about legal procedures. Third, migration law is implemented in an atmosphere of suspicion, which has a negative impact on trust between migrants and state officials â and on transparency. We thus demonstrate how procedural safeguards become empty and routinised, aggravating the structural violence at the heart of the distinction between citizens and non-citizens in interactions with the state
Einfluss von DiÀten aus konventioneller und biologischer Erzeugung auf Fruchtbarkeitsparameter bei Kaninchen
In order to test the effect of organic vs. conventional diets on fertility traits, we conducted
an on-farm study with female rabbits. Eight groups of seven to eight female rabbits
kept in systems with litter were fed ad libitum with either organic or conventional pellets.
Offspring was weaned with approx. 28 days. In the first series analysed, the
conception rate was higher in the conventional groups. Diet type had no significant
influence on that trait. Nevertheless, a significant influence of diet on litter size was
found: organically fed female rabbits produced more offspring per litter. The organic
groups also showed higher rates of weaned animals, despite of a slightly higher mortality
of offspring in these groups, but differences for both traits were not significant
compared to conventional animals. Inconsistency of findings in the first series of this
study concerning the effect of different diets on fertility traits were also found in literature.
Data from the currently running second series will show whether the slightly
positive effect of organic diet will become more evident
Akzeptanz von Futterpflanzen mit Vorkommen von kondensierten Tanninen bei Schafen und ihre Gehalte an nutzbarem Rohprotein
Plants with moderate contents of condensed tannins are assumed to have anthelmintic Plants with moderate contents of condensed tannins are assumed to have anthelmintic properties and to improve protein supply of ruminants by reducing its ruminal degradability. In the present study, birdsfoot trefoil (Lotus corniculatus), chicory (Cychorium intybus) and sainfoin (Onobrychis viciifolia), suitable to be grown in Central Europe, were tested for their suitability as feed for ruminants. Sainfoin proved to be the most promising forage plant since it was very well accepted by the sheep and presented the highest content of utilizable crude protein as determined in vitro. Only few condensed tannins were detected in chicory. Further in vivo studies are required to confirm a better metabolic protein supply of ruminants when fed sainfoin
Effect of long-term oral betablocker treatment on myocardial blood flow and coronary flow reserve in CAD-patients assessed with PET
Far-infrared induced current in a ballistic channel -- potential barrier structure
We consider electron transport in a ballistic multi-mode channel structure in
the presence of a transversely polarized far-infrared (FIR) field. The channel
structure consists of a long resonance region connected to an adiabatic
widening with a potential barrier at the end. At frequencies that match the
mode energy separation in the resonance region we find distinct peaks in the
photocurrent, caused by Rabi oscillations in the mode population. For an
experimental situation in which the width of the channel is tunable via gates,
we propose a method for reconstructing the spectrum of propagating modes,
without having to use a tunable FIR source. With this method the change in the
spectrum as the gate voltage is varied can be monitored.Comment: Submitted to Phys. Rev.
Effects of Storage Time and Thawing Method on Selected Nutrients in Whole Fish for Zoo Animal Nutrition
Piscivores in human care receive whole fish that were frozen, stored and thawed before feeding. Nutrient losses have been documented, but exact changes during storage and with different thawing methods are unknown. Primarily, it was hypothesized that frozen fish lose different vitamins and trace minerals during a storage period of six months. Secondly, that different thawing methods have a significant influence on the degree of vitamin loss. Three fish species, herring (Clupeus harengus), mackerel (Scomber scombrus) and capelin (Mallotus villosus) were analyzed at four time points within a storage period of 6 months at â20 °C. At each time point, three thawing methods were applied: thawing in a refrigerator (R), thawing at room temperature (RT), and thawing under running water (RW). The following nutrients were analyzed: vitamin A, B1, D3 and E, iron (Fe), copper (Cu), zinc (Zn) and selenium (Se). The statistical method used was a linear mixed effect model. Cu was below detection limits in all analyzed samples, vitamin B1 in most analyzed herring (44/48 samples) and capelin (in 25/36 samples), respectively. In addition, the vitamin D3 concentration was also below detection limits in half of the capelin samples (18/36). No concentration changes of Fe (p = 0.616), Zn (p = 0.686) or Se (p = 0.148) were observed during a storage period of six months, in contrast to a significant decrease in vitamin A (p = 0.019), D3 (p = 0.034) and E (p = 0.003) concentrations. Thawing fish with different thawing methods did not result in concentration changes of Fe (p = 0.821), Zn (p = 0.549) or Se (p = 0.633), but in a significant concentration change of vitamin A (p = 0.002). It is essential to supplement vitamins B1 and E in diets containing whole fish to avoid deficiencies in piscivorous species, and care should be taken not to store fish longer than six months, due to the depletion of vitamins A, D3 and E
Content Marketing Studie 2021 : Einsatz und Verbreitung des Content Marketing in der Schweiz
Immer mehr Unternehmen setzen im Rahmen ihrer Marketingkommunikation auf Content Marketing. Dies ist das eindeutige Ergebnis der vorliegenden Studie, fĂŒr welche rund 670 Schweizer Unternehmen befragt wurden. Mehr als die HĂ€lfte von ihnen setzt Content Marketing bereits aktiv ein â und zwar unabhĂ€ngig von der Unternehmensgrösse. Aktuell gehen rund ein Drittel des Marketing Budgets ins Content Marketing. WĂ€hrend hier ein grosses Potenzial fĂŒr die Positionierung von Unternehmen und die Steigerung des Absatzes liegt, ist Content Marketing durchaus anspruchsvoll. Schwierigkeiten haben die Unternehmen bei der regelmĂ€ssigen und vor allem auch qualitativ wertvollen Produktion von Content. Hier setzen einige auf externe Dienstleister.
Die vorliegende Studie untersucht die Nutzung von Content Marketing in der Schweiz. Mit einem standardisierten Online Fragebogen wurden hierfĂŒr rund 670 Schweizer Unternehmen aus allen Landesteilen und Branchen befragt, wobei 80% hiervon zu den Grossunternehmen gehören, jeweils 10% zu den kleinen und mittleren Unternehmungen. Die aktuelle Studie stellt somit eine Fortsetzung der ZHAW Content Marketing Studie aus dem vergangenen Jahr (BĂ€chler et al., 2020) dar und baut auf dieser auf. Sie gestaltet sich aber inhaltlich umfassender und geht detaillierter auf das VerstĂ€ndnis, die Nutzung und die Umsetzung von Content Marketing in der Schweiz ein. Gleichzeitig wurde die Grundgesamtheit der befragten Unternehmen erweitert und der Fokus auf Grossunternehmen gelegt.
Die Ergebnisse der diesjÀhrigen Studie zeigen deutliche Entwicklungen auf: wÀhrend im vergangenen Jahr 80% der Unternehmen angaben, keine Erfahrungen mit Content Marketing zu haben, gaben in diesem Jahr mehr als die HÀlfte (56%) der Unternehmen an, Content Marketing bereits aktiv zu nutzen. Die ProzentsÀtze unterscheiden sich dabei zwischen grossen, mittleren, und kleinen Unternehmen kaum. 60% der Unternehmen, die aktuell kein Content Marketing einsetzen, haben vor, dies in Zukunft zu tun. Die Bedeutung, wie auch die Nutzung, von Content Marketing hat also klar zugenommen.
Wie die Studie weiter aufzeigt, verfolgen Unternehmen mit dem Content Marketing eine duale Zielsetzung. Einerseits sollen Kunden an Unternehmen gebunden und die Unternehmensmarken auf dem Markt positioniert werden. Andererseits dient Content Marketing vielen Unternehmen dazu, konkrete Absatz- und Umsatzziele zu erreichen. Die grosse Mehrheit der Unternehmen verfolgt dazu im Content Marketing Bereich eine Strategie mit klaren Verantwortlichkeiten, Zielsetzungen und mehr oder weniger weitreichenden Regelungen.
Content Marketing profitiert grundsĂ€tzlich von der FĂŒlle an Formaten und Instrumenten, die zur Verbreitung der eigenen Inhalte genutzt werden können. Zu den beliebtesten Content Marketing Instrumenten gehören Artikel auf der eigenen Webseite wie auch Social Media BeitrĂ€ge und E-Mail-Newsletter. Bei der Streuung der Inhalte setzen die Unternehmen auf die eigenen, aber vielfach auch auf bezahlte KommunikationskanĂ€le.
Die Erfolgsmessung gehört nach wie vor zu den grössten Herausforderungen im Content Marketing. Dennoch haben die meisten Unternehmen hier klare Kennzahlen zur Evaluation der bereitgestellten Inhalte definiert und messen diesen auch eine grosse Bedeutung bei. Ebenfalls schwer tun sich Unternehmen damit, regelmĂ€ssigen und qualitativ guten Inhalt zu produzieren. In diesem Bereich tun sich Möglichkeiten fĂŒr externe Dienstleister auf, die aktuell noch wenig genutzt werden. Derzeit arbeiten 40% der Unternehmen im Rahmen des Content Marketings mit externen Dienstleistern zusammen, v.a. zur Content Produktion im Bereich Video, Foto und Layout.
Die Ausgaben fĂŒr das Content Marketing variieren von Unternehmen zu Unternehmen. Rund 20% der Unternehmen setzen unter 10â000 Franken im Jahr fĂŒr Content Marketing ein, rund 30% zwischen 25â000 und 100â000, und ebenfalls rund 40% ĂŒber 250â000 im Jahr. Aktuell setzen die Unternehmen im Schnitt 33 Prozent ihres Marketing-Budgets fĂŒr Content Marketing ein. Die meisten Unternehmen gehen davon aus, dass das Content Marketing Budget in den nĂ€chsten Monaten gleichbleiben (21%) oder steigen (18%) wird
