Congested curricula and incompatible goals: the curious absence of ICT from school-based learning in China

Worldwide, information and communication technologies (ICT), particularly in the sense of digital literacy, are increasingly considered as both inevitable and indispensable parts of the school curriculum. Also, international student assessment studies like PISA have on several occasions assessed computer and information literacy. Additionally, classrooms, teaching and learning, as well as school a

Morphological and optical properties and evolutionary changes of the eye lenses of terrestrial gastropod molluscs (Pulmonata, Stylommatophora)

Morphological and optical properties were studied and also evolutionary changes of the eye lenses of some species of terrestrial gastropod pulmonate molluscs were traced. It was demonstrated that all examined properties of the lenses are typical for terrestrial pulmonates. In the course of evolution due to habitat shift by mollusks the lenses were changed only slightly.

Solvent-free and biocompatible multiphased organic-inorganic hybrid nanocomposites

Biocompatible chemically cross-linked organic-inorganic (O-I) hybrid nanocomposites were developed using a new atoxic, simple and fast, solvent-free pathway. Poly(ϵ-caprolactone) (PCL) and poly(ethylene glycol) (PEG), which are both biocompatible, were used as the organic moieties (at different PCL/PEG ratios), while in situ synthesized polysilsesquioxanes made up the inorganic moiety. The O-I hyb

Could Easier Access to University Improve Health and Reduce Health Inequalities?

This paper estimates the impact of university education on medical care use and its income related inequality. We do this by exploiting an arbitrary university eligibility rule in Sweden combined with regression discontinuity design for the years 2003-2013 for students who graduated 2003-2005. We find a clear jump in university attendance due to university eligibility. This jump coincides with a pThis paper estimates the impact of university education on medical care use and its income related inequality.

Media and migration through the lens of mediatization and transnationalism

In present paper, the debates around mediatization and transnationalism constitute the backdrop for a discussion on the media and communication practices among Swedish expatriates in the Netherlands and forced migrants from Bosnia in Sweden. The complex relationship between (transnational) identity, place and mobility is studied at three intersections between media and migration: (1) creativity an

The self-organization of plant microtubules inside the cell volume yields their cortical localization, stable alignment, and sensitivity to external cues

Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, and thus control mechanical anisotropy of the cell wall. Here we analyze how, in turn, cell shape may influence microtubule behavior. Buidling upon previous models that confined m

Analysis of nanoparticle biomolecule complexes

Nanoparticles exposed to biological fluids adsorb biomolecules on their surface forming a biomolecular corona. This corona determines, on a molecular level, the interactions and impact the newly formed complex has on cells and organisms. The corona formation as well as the physiological and toxicological relevance are commonly investigated. However, an acknowledged but rarely addressed problem in

Simulation-based quantification of native T1 and T2 of the myocardium using a modified MOLLI scheme and the importance of Magnetization Transfer

Quantitative cardiovascular Magnetic Resonance Imaging techniques are gaining wide acceptance within the MR community due to their potential to diagnose non-localized disease, guide therapy and improve patient outcome. During the last decade, there has been an increasing interest for developing new techniques that allow for simultaneous quantification of both T1 and T2 maps of myocardium. Newer st

Does risk-adjusted payment influence primary care providers' decision on where to set up practices?

Background: Providing equal access to health care is an important objective in most health care systems. It is especially pertinent in systems like the Swedish primary care market, where private providers are free to establish themselves in any part of the country. To improve equity in access to care, 15 out 21 county councils in Sweden have implemented risk-adjusted capitation based on the Care N

Economic impact of clinical mastitis in a dairy herd assessed by stochastic simulation

The main aim of the present study was to examine the economic consequences of a reduction of the incidence of clinical mastitis (CM) at herd level under current Swedish farming conditions. A second aim was to ask whether the estimated cost of CM alters depending upon whether the model reflects the fact that in different stages of lactation CM gives rise to different yield-loss patterns or postulat

Economic impact of clinical mastitis in a dairy herd assessed by stochastic simulation using different methods to model yield losses

The main aim of the present study was to examine the economic consequences of a reduction in the incidence of clinical mastitis (CM) at herd level under current Swedish farming conditions. A second objective was to ask whether the estimated cost of CM alters depending upon whether the model reflects the fact that in different stages of lactation, CM gives rise to different yield-loss patterns or p

Economic consequences of mastitis and withdrawal of milk with high somatic cell count in Swedish dairy herds

The main aim was to assess the impact of mastitis on technical and economic results of a dairy herd under current Swedish farming conditions. The second aim was to investigate the effects obtained by withdrawing milk with high somatic cell count (SCC). A dynamic and stochastic simulation model, SimHerd, was used to study the effects of mastitis in a herd with 150 cows. Results given the initial in

Relationship between somatic cell count and milk yield in different stages of lactation

The association between somatic cell count (SCC) and daily milk yield in different stages of lactation was investigated in cows free of clinical mastitis (CM). Data were recorded between 1989 and 2004 in a research herd, and consisted of weekly test-day (TD) records from 1,155 lactations of Swedish Holstein and Swedish Red cows. The main data set (data set A) containing 36,117 records excluded TD

Mastitis control in Swedish dairy herds

The aim of this study was to investigate which preventive measures targeting mastitis are implemented in Swedish dairy herds with different housing and milking systems. Data were collected through a self-administered postal questionnaire sent to 898 dairy farmers, stratified by housing and milking system, in May 2011. The questionnaire contained general questions about the herd and the person resp

Which preventive measures against mastitis can increase the technical efficiency of dairy farms?

The aim of this paper was to explore if, and in that case how, various preventive measures against mastitis influenced the whole-farm economic outcome, measured as technical efficiency, of a sample of specialised dairy farms in Sweden. In particular, the paper aimed at analysing whether a change to preventive measures applied by fully efficient farms would be a way for inefficient farms to become

Relationship between herd-level incidence rate of energy-related postpartum diseases, general risk factors and claw lesions in individual dairy cows recorded at maintenance claw trimming.

Laminitis and energy-related postpartum diseases share several risk factors, indicating a common etiology. Thus, a herd's incidence rate of energy-related postpartum diseases, such as displaced abomasum and clinical ketosis, might reflect the likelihood of cows to suffer from laminitis-related claw lesions. The aim of this study was to investigate the association between herd-level incidence rate
