Ecological regime shifts typically result in abrupt changes in ecosystem structure through several trophic levels, which leads to rapid ecosystem reconfiguration between regimes. An interesting aspect of the impact of regime shift is that alternative regimes may induce distinct shifts in energy pathways; these have been less tested than structural changes. This paper addresses this by using stable

For many common global diseases, such as cancer, diabetes, neurodegenerative and cardiovascular diseases there is an unmet need for diagnosing early indications of disease that could enable medical intervention and early treatment. For example, cigarette smoking causes a variety of deadly diseases including lung cancer, hypertension, chronic obstructive pulmonary disease (COPD) and cardiovascular

Background: Increasingly evidence is emerging from south East Asia, southern and east Africa on the burden of default to follow up care after a positive cervical cancer screening/diagnosis, which impacts negatively on cervical cancer prevention and control. Unfortunately little or no information exists on the subject in the West Africa sub region. This study was designed to determine the proportio

Sweden experienced a decline in inter-county real wage differentials for agricultural workers between 1860 and 1940, historical evidence of early labour market integration well before widespread unionization in agriculture occurred. By means of dynamic panel data analysis, this paper examines whether internal and external migration caused real wage beta convergence across Swedish counties. To acco

Background and purpose Spontaneous osteonecrosis of the knee (SPONK) is a painful lesion in the elderly, frequently leading to osteoarthritis and subsequent knee surgery. We evaluated the natural course and long-term consequences of SPONK in terms of need for major knee surgery. Methods Between 1982 and 1988, 40 consecutive patients were diagnosed with SPONK. The short-term outcome has been report

This paper investigates trust behavior in situations where decision-makers are large groups and the decision mechanism is collective. Theories from behavioral economics and psychology suggest that trust in such situations may differ from interindividual trust. The experimental results here reveal a large difference in trust but not in trustworthiness between the individual and collective setting.

The feasibility of using degenerate four-wave mixing (DFWM) for hot gas thermometry in the mid-infrared spectral region is, for the first time, demonstrated by probing molecular ro-vibrational transitions of water. DFWM spectra of hot water were recorded in specially designed flames, providing a series of temperatures varying from 1000 to 1900 K and, the dramatic spectral structure variations were

Pollination of insect pollinated crops has been found to be correlated to pollinator abundance and diversity. Since organic farming has the potential to mitigate negative effects of agricultural intensification on biodiversity, it may also benefit crop pollination, but direct evidence of this is scant. We evaluated the effect of organic farming on pollination of strawberry plants focusing on (1) i

Organisms usually benefit from heterogeneous conditions, but, by doing so, may reduce the degree of heterogeneity. The question therefore arises how heterogeneity is maintained. We investigated within-year spatiotemporal patterns in a monospecific stand of a submerged plant (fennel pondweed, Potamogeton pectinatus), with the novelty that we distinguished between different forms of heterogeneity: s

Maria Sjöberg behandlar i Kritiska tankar om historia hur ett antal skeden i världshistorien har framställts och framställs i historiska verk.

Prompted by persistent dissatisfaction with research and research publications in organization studies, we critically discuss the standardization of research and publications into formulaic patterns that constrain the imagination and creativity of scholars and restrict the social relevance of their work. Formulaic research involves extreme specialization, an incrementalist and ultra-cautious attit

One of the most influential factors determining the growth and composition of soil bacterial communities is pH. However, soil pH is often correlated with many other factors, including nutrient availability and plant community, and causality among factors is not easily determined. If soil pH is directly influencing the bacterial community, this must lead to a bacterial community growth optimised fo

A portable high resolution soft x-ray and extreme ultraviolet (EUV) spectrometer has been developed for spectroscopic research at the Shanghai Electron Beam Ion Trap (EBIT) laboratory. A unique way of aligning the grazing incidence spectrometer using the zero order of the grating is introduced. This method is realized by extending the range of the movement of the CCD detector to cover the zero ord

This paper examines the dynamics of a technological innovator network (TIN) of a state-owned textile company in underdeveloped southwest China. It addresses two research questions: how the structure of the TIN evolved in the past 10 years; and what impact it had on the technological performance of the firm. The case study reveals that the general structure of the TIN and the positioning of the act

Insects have developed different structures to adhere to surfaces. Most common are smooth and hairy attachment pads, while nubby pads have also been described for representatives of Mantophasmatodea, Phasmida and Plecoptera. Here we report on the unusual combination of nubby and smooth tarsal attachment structures in the !nara cricket Acanthoproctus diadematus. Their three proximal tarsal pads (eu
