Grassroots Innovations (GI) have became a successful mechanism developed by the associative capacity of people that seek to provide solutions to their own problems relying on the values of solidarity and reciprocity while striving for social transformation (Smith and Seyfang, 2007; Seyfang and Haxeltine, 2012). However, GI still endure three challenges, namely: adaptation vs. transformation, local
Theorizing embeddedness requires sensitivity to the dynamic and multi-layered contexts that entrepreneurship is situated within. Social or network embeddedness offers explanation for how both social and for-profit entrepreneurs can leverage resources within their local environment. Institutional embeddedness is concerned with how the environment for entrepreneurship is shaped by social structures,
A significant part of our cultural heritage consists of wood. Research on historical wooden structures and artefacts thereby provides knowledge of people’s daily lives and the society in which they lived. Dendrochronology is a well-established dating method of wood that can also provide valuable knowledge about climate dynamics, environmental changes, silviculture, and cultural transformations.

X-ray diffractometers primarily designed for surface X-ray diffraction are often used to measure the diffraction from powders, textured materials and fiber-texture samples in 2θ scans. Unlike in high-energy powder diffraction, only a fraction of the powder rings is typically measured, and the data consist of many detector images across the 2θ range. Such diffractometers typically scan in direction
Detta är en debattartikel. Det är skribenten som står för åsikterna som förs fram i texten, inte Aftonbladet.För det första behöver konsumtionen av animalisk föda minska. Detta minskar utsläppen av den kraftfulla växthusgasen metan som idisslare producerar, skriver Henrik Smith, professor i zooekologi.
We propose a new model that estimates the long- and short-run components of the variances and covariances. The advantage of our model to the existing DCC-based models is that it uses the same form for both the variances and covariances and estimates these moments simultaneously. We apply this model to obtain long- and short-run factor betas for industry test portfolios. We find that the risk premi

BACKGROUND: Our aim was to investigate the prognostic potential of circulating dipeptidyl peptidase 3 (cDPP3) to predict mortality and development of organ dysfunction in a mixed intensive care unit (ICU) population, and for this reason, we analysed prospectively collected admission blood samples from adult ICU patients at four Swedish hospitals. Blood samples were stored in a biobank for later ba
CO2 chemistry has received significant interest in recent time, due to the greenhouse effects of CO2 emissions and the resulting climate change. CO2 reduction reactions, such as methanol synthesis and reverse water-gas shift, is providing a route for recycling of CO2 and thus limiting the CO2 emissions. These reactions are commonly performed over Cu-based catalysts, making the interaction of CO2 a
Proton halo effects in the 8B+64Zn reaction at an energy around 1.5 times the Coulomb barrier have been studied at HIE-ISOLDE CERN using, for the first time, the only existing postaccelerated 8B beam. This, together with the use of a high granularity and large solid angle detection system, allowed for a careful mapping of the elastic angular distribution, especially in the Coulomb-nuclear interfer
Background: The contact allergy prevalences in patch-tested patients are usually higher than those in the population, owing to morbidity-driven selection. Objectives: To examine the differences between two samples, one from the population, one from the patch test clinic, in one area of Germany (Jena, Thuringia). Methods: Between August 2008 and October 2011, a total of 519 participants of the popu
Introduction: Ischemic spinal cord injury (SCI) is a serious complication of complex aortic repair. Prophylactic cerebrospinal fluid (CSF) drainage, used to decrease lumbar cerebrospinal fluid (CSF) pressure, enables monitoring of CSF biomarkers that may aid in detecting impending SCI. We hypothesized that biomarkers, previously evaluated in traumatic SCI and brain injury, would be altered in CSF
Introduction: The heart and arterial system are equally affected by arteriosclerosis/atherosclerosis. There is a constant interaction between the left ventricular (LV) function and the arterial system, termed ventricular-arterial coupling (VAC), which reflects the global cardiovascular efficiency. VAC is traditionally assessed by echocardiography as the ratio of effective arterial elastance (Ea) o
It is well-known that Littlewood-Paley operators formed with respect to lacunary sets of finite order are bounded on Lp(ℝ) for all 1 < p < ∞. In this note it is shown that 'Equation Presented' where SIE2 denotes the classical Littlewood-Paley operator formed with respect to the second order lacunary set E2 = {±(2k -2l) : k, l ∈ ℤ with k > l}. Variants in the periodic setting and for certain lacuna
Background Impaired orthostatic blood pressure response and syncope confer a high risk of falls and trauma. The relationship between a history of unexplained syncope and orthostatic hypotension (OH) with subsequent fractures, however, has not been thoroughly examined. In this study, we aimed to investigate the relationship between previous hospital admissions due to unexplained syncope and OH and
Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. Aerosol particles can interact with climate-related processes in the atmosphere either directly by absorbing or refle
