Unpacking entrepreneurial learning: How prior related experience and uncertainty affect learning behaviors

This study provides insights into why new ventures adopt different learning behaviors when managing uncertainty associated with commercializing products, services or processes. The research builds on a comparative case-study methodology using 21 in-depth semi-structured interviews and company documents. The comparative analysis builds up to an overall understanding of how new ventures develop thei

The Stability and Growth Pact. Lessons from the Great Recession

While current instruments of EU economic policy coordination helped stave off a full- scale depression, the post-2007 global financial and economic crisis has revealed a number of weaknesses in the Stability and Growth Pact, the EU framework for fiscal surveillance and fiscal policy coordination. This paper provides a diagnosis of how the SGP faired ahead and during the present crisis and offers a

Urban infiltration in cold climate

The implementation of Sustainable Urban Drainage Systems (SUDS) in the northern hemisphere is confronted with the problem of decreased infiltration during winter because of frozen soils. The goal of this research was to assess the winter infiltration capacity of a grass swale and natural vegetation cover during frequent freeze-thaw cycles. Infiltration was measured with eight single-ring infiltrom

Regional GDP before GDP : A methodological survey of historical national accounts

Regional Studies is inextricably intertwined with history. Cultural and institutional legacies inform choices between different policy options, meaning that the past plays a crucial role in how we think about regional economic development, planning and policy.Through a selection of accessible theoretical, methodological and empirical chapters, this book explores the connections between regional de

More power to the people : Electricity adoption, technological change and social conflict

History has shown that new technology can disrupt societies, and current developments in automation have raised anxious speculation on what might happen if stable middle-class jobs are taken over by machines. This column analyses the impact of technological change on labour markets and social protests, taking the case of the adoption of electricity in early 20th century Sweden. It finds that elect

Impact of long-term N fertilisation on CO2 evolution from old and young SOM pools measured during the maize cropping season

The relationship between carbon (C) inputs and nitrogen (N) fertilisation is a key element of soil organic matter (SOM) dynamics, which remains poorly resolved. In temperate climates, it is critical to investigate the interactive effect of C and N inputs on SOM stabilisation under low or high substrate availability. We measured SOM content and in situ soil respiration in a long-term field experime

Interactive priming effect of labile carbon and crop residues on SOM depends on residue decomposition stage : Three-source partitioning to evaluate mechanisms

Inputs of crop residues and labile C (e.g. root exudates) can affect the decomposition rate of soil organic matter (SOM) through the priming effect (PE). Most previous priming studies describe the addition of single labile or residue C, ignoring the interactions of labile C and fresh or decaying crop residues commonly present in field conditions. Using a dual 13C/14C labelling approach in a 62-day

Priming effects induced by glucose and decaying plant residues on SOM decomposition : A three-source 13C/14C partitioning study

Decomposition of soil organic matter (SOM) may either increase or decrease after fresh organic inputs, the phenomena which are termed as “priming effect”. Crop residues and labile C additions can prime SOM decomposition, but it is not known how labile C inputs affect SOM in the presence of decaying plant residues varying in quality (e.g. from previous crops, a common situation in arable soils). We

Massive MIMO with a Generalized Channel Model : Fundamental Aspects

Massive multiple-input multiple-output (MIMO) is becoming a mature technology, and has been approved for standardization in the 5G space. Although there are many papers on the theoretical analysis of massive MIMO, the majority of relevant work assumes the simplified, yet overly idealistic, Kronecker-type model for spatial correlation. Motivated by the deficiencies of the Kronecker model, we invoke

Positron emission tomography visualized stimulation of the vestibular organ is localized in Heschl's gyrus

The existence of a human primary vestibular cortex is still debated. Current knowledge mainly derives from functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) acquisitions during artificial vestibular stimulation. This may be problematic as artificial vestibular stimulation entails coactivation of other sensory receptors. The use of fMRI is challenging as the strong

Phase Noise Compensation for OFDM Systems Exploiting Coherence Bandwidth

Millimeter-wave (mmWave) systems must overcome severe phase noise impairment to exploit its full advantage (e.g. high data rate). However, the estimation of phase noise combined with wireless channel requires not only high-computational complexity, but also does not guarantee a stable solution. In this paper, the fact that the coherence bandwidth of a mmWave system is much larger than those of con

Surgical management of cytologically indeterminate thyroid nodules

Nodules in the thyroid are frequent. Preoperative investigations including fine-needle cytology and ultrasound cannot in all patients rule out malignancy. Thus, surgical excision for histopathologic examination is often needed. In this narrative review, we examine aspects of the surgical management of indeterminate thyroid nodules, using a comprehensive review of the available literature. The auth

Understanding acceleration : An interplay between different mathematics and physics representations

Acceleration is often viewed as abstract - but when a person accelerates, e.g. in a car or on swings, trampolines, carousels or rollercoasters, the force required for the acceleration is felt throughout the body. If acceleration is introduced as force divided by mass rather than as a second derivative of displacement, the concept can be made accessible to much younger learners, such as 10-year old

Training teachers to use playgrounds in physics teaching

Climbing racks, carousels, swings and slides can be used for many experiments and demonstrations that offer suprising results, often challenging students' understanding of motion. This paper describes activities used in professional development workshops for teachers on the use of playgrounds in physics teaching. Toys and other simple equipment complement the experience of the body. In addition, s

Antibody-Fragments: Protein Engineering, Process Development, and their Application as Affinity Ligands

Monoclonal antibody (mAb) fragments have become the formats of choice for both biopharmaceuticals and ligands in analytical and preparative applications. Their smaller size enables additional advantages over full-length mAbs, such as improved tissue penetration, faster blood clearance for diagnostic applications, improved capacity, and enablement of multivalent formatting.

High spin states of the normally deformed bands of y 83

Level lifetime and side-feeding time measurements were performed on the excited states of the normally deformed bands of Y83 using the Doppler-shift attenuation method (DSAM). The high spin states of Y83 were populated using the fusion-evaporation reaction Ni58(S32,α3p)Y83 at 135 MeV. Twenty-two level lifetime and side-feeding times were determined in most of the cases by comparing the line shapes
