How migration motives change over distance: evidence on variations across socioeconomic and demographic groups

Migration researchers have long known that the motives for changing place of residence vary over migration distance. Typically, short-distance moves are regarded as motivated by housing considerations and longer-distance moves primarily by employment considerations. Using a large-scale survey on migration motives, this paper explores how migration motives change over migration distance. Particular

GCM characteristics explain the majority of uncertainty in projected 21st century terrestrial ecosystem carbon balance

One of the largest sources of uncertainties in modelling of the future global climate is the response of the terrestrial carbon cycle. Studies have shown that it is likely that the extant land sink of carbon will weaken in a warming climate. Should this happen, a larger portion of the annual carbon dioxide emissions will remain in the atmosphere, and further increase global warming, which in turn

Why human rights fail to protect undocumented migrants

In this article, I depart from the factual difficulties of undocumented migrants to access a state’s protection mechanisms for avowedly universal human rights. I relate this aporia to two competing conceptions of territorial jurisdictions. Drawing on the Convention on the Rights of the Child and the Migrant Workers Convention, I separate the sphere of the political community (the polis) and that o

Importance of Inoculum Properties on the Structure and Growth of Bacterial Communities during Recolonisation of Humus Soil with Different pH.

The relationship between community structure and growth and pH tolerance of a soil bacterial community was studied after liming in a reciprocal inoculum study. An unlimed (UL) humus soil with a pH of 4.0 was fumigated with chloroform for 4 h, after which < 1 % of the initial bacterial activity remained. Half of the fumigated soil was experimentally limed (EL) to a pH of 7.6. Both the UL and the EL

Solar energy for electricity and fuels.

Solar energy conversion into electricity by photovoltaic modules is now a mature technology. We discuss the need for materials and device developments using conventional silicon and other materials, pointing to the need to use scalable materials and to reduce the energy payback time. Storage of solar energy can be achieved using the energy of light to produce a fuel. We discuss how this can be ach

On channel quantization for multi-cell cooperative systems with limited feedback

Coherent multi-cell cooperative transmission, also referred to as coordinated multi-point transmission (CoMP), is a promising strategy to provide high spectral efficiency for universal frequency reuse cellular systems. To report the required channel information to the transmitter in frequency division duplexing systems, limited feedback techniques are often applied. Considering that the average ch

Factors affecting obstetric outcome of singletons born after IVF

BACKGROUND: Singletons born after IVF have an adverse perinatal outcome when compared with singletons in the general population. This study investigates maternal characteristics and IVF-treatment-related variables, for a possible influence on obstetric outcomes. METHODS: Data from all IVF clinics in Sweden, including all IVF singletons born after fresh treatment cycles and own oocytes during 2002-

Cyclists in roundabouts -- Different design solutions.

Whether the safest roundabout design for cyclists is to separate cycle crossings or integrate cyclists with motorists is an extensively discussed issue. Studies using accident statistics indicate that a separated cycle crossing is the safest for high motor vehicle volumes. However, the results have not been satisfyingly explained. This article combines quantitative and qualitative methods in traff

Speciation of Zn in WtE fly ash residues after wet treatment

Waste-to-energy fly ash can be repurposed if treated to limit the leaching of potentially toxic elements such as Zn. Ashes with lime additives can be stabilised via gypsum formation, while those without additives are better suited for acid-leaching treatment (and material recovery). In this study, ashes from grate-fired boilers – three without lime addition and one ash with lime addition – were tr

Sowing Seeds of Change : Feminist collective action for agroecological transformation in Zimbabwe

Avhandlingen undersöker hur kvinnor i Zimbabwes jordbrukssektor tillämpar kollektivt handlande för att främja agroekologisk omvandling och utmana könsrelaterade ojämlikheter. Trots att kvinnor utgör minst 70% av arbetskraften i Zimbabwes jordbrukssektor, marginaliseras de genom ojämlik tillgång till mark, utestängning från strategiska beslut och devalvering av beprövad erfarenhet. Studien bygger pThis thesis examines how women in agricultural communities in Zimbabwe leverage collective action to advance agroecological transformation while challenging systemic gender inequities. It responds to the persistent marginalization of women in Zimbabwean agriculture by investigating how collective action reclaims agency and reshapes agroecological systems. Despite constituting at least 70 % of the

Individually fitting but collectively unfitting blame

People that produce bad outcomes can thereby become the fitting targets of blame, the fitting intensity of which is determined by the badness of the outcomes. In the following paper, I suggest that the amount of blame instances that people are fitting targets of is also determined by the weight of the badness of the outcomes. I use the example of online blame as a paradigmatic case where the amoun

Size matters : effect of screen setup on muscle activity and posture in computer work

AbstractThis research aims to investigate and compare how computers work on five different workstation setups of multiple or large screens and viewing distances (27-inch and 49-inch at 70 or 90 cm viewing distance) affect muscular load in neck/shoulders, working postures, and perceived exertions of non-presbyopic participants.

Abstract in French: Une restauratrice japonaise installée à Vientiane a lancé l’alerte après avoir vu en ligne des hommes se vanter d’avoir acheté des rapports sexuels avec des enfants. Son action a conduit Tokyo à publier un avertissement diplomatique aussi rare que direct. Derrière cet épisode, c’est tout un système d’exploitation sexuelle transnationale qui refait surface, révélant les liens pe

Is eyestrain associated with musculoskeletal strain and visual symptoms?

AbstractEyestrain is a common issue when performing visually demanding work, often accompanied by neck and shoulder strain, as well as visual problems such as dim vision. The aim of this paper is to investigate the association between eyestrain and musculoskeletal strain, as well as the association between eyestrain and visual symptoms. Two regression analyses were conducted on subjective ratings Eyestrain is a common issue when performing visually demanding work, often accompanied by neck and shoulder strain, as well as visual problems such as dim vision.

Bouchra Khalili : Solo exhibition. Louisiana Museum of Modern Art

The exhibition presents a selection of works by Moroccan-French artist Bouchra Khalili (b. 1975), whose multidisciplinary practice develops collaborative strategies of storytelling with members of communities excluded from citizen membership.Combining the traditions of post-independence avant-gardes and conceptual practices, Khalili’s work suggests poetical hypotheses for newer imaginations of com

WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet

We present a detailed study of the large-scale shock front in Stephan’s Quintet, a by-product of past and ongoing interactions. Using integral-field spectroscopy from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), recent 144 MHz observations from the LOFAR Two-metre Sky Survey, and archival data from the Very Large Array and JWST, we obtain new measurements of key shoc

Ignition, combustion modes and NO/N2O emissions in ammonia/n-heptane combustion under RCCI engine conditions

Ammonia has been considered a promising carbon-free fuel for marine engines. However, its low flame speed and high nitrogen oxides (NOx) and nitrous oxide (N2O) emissions present significant challenges. To address these issues, novel combustion concepts, such as ammonia/diesel dual-fuel Reactivity-Controlled Compression Ignition (RCCI) engines, have been proposed. This paper presents a detailed in
