Does prior start-up experience matter for entrepreneurs’ learning? : A comparison between novice and habitual entrepreneurs

Purpose– This paper aims to present a study of the role of prior start‐up experience as a source of learning in the entrepreneurial process. Three learning outcomes are examined with respect to a comparison between habitual and novice entrepreneurs: skills for coping with liabilities of newness, preference for effectual reasoning, and attitudes towards failure.Design/methodology/approach– This is

Vehicular Communication in Obstructed and Non Line-of-Sight Scenarios

Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives.Wireless communication may sometimes be challenging due to obstacles in the physical world that intera

A model for power contributions from diffraction around a truck in Vehicle-to-Vehicle communications

Channel modeling studies in vehicle-to-vehicle (V2V) communications have shown that larger road users act as blocking objects for the communication of surrounding vehicles, dramatically altering the statistical properties of the wireless channel. Without a strong line-of-sight component, packet delivery depends on other propagation mechanisms that are statistically more likely to add destructively

Updated European Association of Urology Guidelines Regarding Adjuvant Therapy for Renal Cell Carcinoma

The European Association of Urology Renal Cell Carcinoma (RCC) guidelines panel updated their recommendation on adjuvant therapy in unfavourable, clinically nonmetastatic RCC following the recently reported results of a second randomised controlled phase 3 trial comparing 1-yr sunitinib to placebo for high-risk RCC after nephrectomy (S-TRAC). On the basis of conflicting results from the two availa

A Systematic Review and Meta-analysis Comparing the Effectiveness and Adverse Effects of Different Systemic Treatments for Non-clear Cell Renal Cell Carcinoma

Context While vascular endothelial growth factor-targeted therapy and mammalian target of rapamycin inhibition are effective strategies in treating clear cell renal cell carcinoma (ccRCC), the most effective therapeutic approach for patients with non-clear cell RCC (non-ccRCC) is unknown. Objective To systematically review relevant literature comparing the oncological outcomes and adverse events o

Local checkpoint inhibition of CTLA-4 as a monotherapy or in combination with anti-PD1 prevents the growth of murine bladder cancer

Checkpoint blockade of CTLA-4 results in long-lasting survival benefits in metastatic cancer patients. However, patients treated with CTLA-4 blockade have suffered from immune-related adverse events, most likely due to the breadth of the induced T-cell activation. Here, we investigated the efficacy of a local low-dose anti-CTLA-4 administration for treatment of subcutaneous or orthotopic murine bl

Molecular detection of Babesia capreoli and Babesia venatorum in wild Swedish roe deer, Capreolus capreolus

Background: The epidemiology of the zoonotic tick-transmitted parasite Babesia spp. and its occurrence in wild reservoir hosts in Sweden is unclear. In European deer, several parasite species, including Babesia capreoli and the zoonotic B. venatorum and B. divergens has been reported previously. The European roe deer, Capreolus capreolus, is an important and common part of the indigenous fauna in

Introduktion:Studiet af performance er i kulturteoretisk sammenhæng karakteriseret ved, at det på én og samme tid peger på et genstandsfelt og på et analytisk perspektiv. Iscenesættelse, materialenærhed, proces, deltagelse, subversion, gentagelse og transformation er ikke kun centrale begreber i forståelsen af performancekunst som felt, men er det også når performanceperspektivet anvendes som anal

Slow Interatomic Coulombic Decay of Multiply Excited Neon Clusters

Ne clusters (∼5000 atoms) were resonantly excited (2p→3s) by intense free electron laser (FEL) radiation at FERMI. Such multiply excited clusters can decay nonradiatively via energy exchange between at least two neighboring excited atoms. Benefiting from the precise tunability and narrow bandwidth of seeded FEL radiation, specific sites of the Ne clusters were probed. We found that the relaxation

Isoprene suppression of new particle formation : Potential mechanisms and implications

Secondary aerosols formed from anthropogenic pollutants and natural emissions have substantial impacts on human health, air quality, and the Earth's climate. New particle formation (NPF) contributes up to 70% of the global production of cloud condensation nuclei (CCN), but the effects of biogenic volatile organic compounds (BVOCs) and their oxidation products on NPF processes in forests are poorly

Development and characterization of high suppression and high étendue narrowband spectral filters

The present work addresses critical issues in constructing high suppression, narrowband spectral filters in rare-earth-ion-doped crystals, mainly targeting the application of ultrasound optical tomography but is also applicable for areas such as quantum memories, self-filtering of laser frequencies, and other applications relying on high absorption in rare-earth-ion-doped crystals. The polarizatio

Tolerance in the United States : Does economic freedom transform racial, religious, political and sexual attitudes?

Tolerance is a distinguishing feature of Western culture. Still, it varies between and within countries, as well as over time, and irrespective of whether one values it for its own sake or for its beneficial consequences, it becomes important to identify its determinants. In this study, we investigate whether the character of economic policy plays a role, by looking at the effect of changes in eco

Automatic segmentation of lungs in SPECT images using active shape model trained by meshes delineated in CT images

This paper presents a fully automated method for segmentation of 3D SPECT ventilation and perfusion images. It relies on statistical information on lung shape derived by CT manual segmentation and its main processing steps are: shape model extraction, binary segmentation, positioning of mean shape in SPECT images and iterative shape adaptation based on intensity profiles and on what is considered

Bin-packing based optimisation of EON Networks with S-BVTs

In the paper we address an important problem in minimum cost design of Elastic Optical Networks (EON), namely the problem of optimizing the configurations of Sliceable-Bandwidth Variable Transceivers (S-BVT) at the EON nodes. We first show how this optimization problem can be viewed and modeled as a combination of three bin-packing subproblems, with additional constraints ensuring feasibility of t

Regional sea-surface temperatures explain spatial and temporal variation of summer precipitation in the source region of the Yellow River

The summer precipitation (June–September) in the source region of the Yellow River accounts for about 70% of the annual total, playing an important role in water availability. This study divided the source region of the Yellow River into homogeneous zones based on precipitation variability using cluster analysis. Summer precipitation trends and teleconnections with global sea-surface temperatures

Sensitive detection of oxygen using a diffused integrating cavity as a gas absorption cell

In this study, an oxygen monitoring system was demonstrated for sensitive oxygen detection. The system is based on tunable diode laser absorption spectroscopy (TDLAS) and wavelength modulation spectroscopy (WMS). Stable 2nd-harmonic signals of oxygen were detected by measuring the oxygen P9 absorption line at 764.38. nm. In the detection, a cubic diffuse integrating cavity was employed as a gas ab

Streamlining photovoltaic deployment : The role of local governments in reducing soft costs

Steep declines in photovoltaic (PV) technology prices have directed attention to the so-called soft costs associated with PV deployment. This paper focuses on one element of soft costs: those that arise from local permitting and inspection processes typically being handled by municipalities. Based on a literature review, the paper compares the status of local PV permitting in the US and Germany. R
