Strategic agility explanations for managing franchising expansion during economic cycles
2017
Purpose This paper aims to demonstrate how franchising firms can manage system expansion by weathering the economic effects of a location (i.e. country-level economic cycles) by shifting their resources. Design/methodology/approach The authors use a comprehensive database of 151 US hybrid franchising organizations, including observations for the years between 2001 and 2008. Data analysis is conducted with count model panel data with a Poisson distribution. Findings The model reveals a curvilinear U-shaped relationship between location (i.e. economic cycles) and franchising expansion. Originality/value This study contributes to competitiveness literature by showing how franchising firms res…
Profit Sharing the Firm-Size Wage Premium
2017
This study analyzes the relationships among wages, firm size, and profit sharing schemes. We develop a simple theoretical model and explore the relationship empirically using high-quality panel data. The theoretical model shows that the firm-size wage premium decreases in the presence of profit sharing. The empirical results based on rich matched employee-employer data for private sector wage earners in Finland show that the firm-size wage premium is modest, and it becomes negligible when we account for profit sharing and covariates describing assortative matching and monopsony behavior. The analysis suggests that profit sharing schemes embody effects of firm-specific unobservables that rai…
A Note on the High Stability of Happiness: The Minimal Effects of a Nuclear Catastrophe on Life Satisfaction
2008
Using life satisfaction as a direct measure of individual utility has become popular in the empirical economic literature. In this context, it is crucial to know what circumstances or changes the measure is sensitive to. Is life satisfaction a volatile concept that is affected by minor changes in life circumstances? Or is it a reliable measure of personal happiness? This paper will analyze the impact of a catastrophe, namely the nuclear catastrophe of Chernobyl, on life satisfaction. I use longitudinal data from the German Socio-Economic Panel Study and especially information collected on a monthly basis which allows the researcher to study calendar effects. The following clear-cut results …
TMS-EEG signatures of glutamatergic neurotransmission in human cortex
2019
AbstractNeuronal activity in the brain is regulated by an excitation-inhibition balance. Glutamate is the main excitatory neurotransmitter. Transcranial magnetic stimulation (TMS) evoked electroencephalographic (EEG) potentials (TEPs) represent a novel way to quantify pharmacological effects on neuronal activity in the human cortex. Here we tested TEPs under the influence of a single oral dose of two anti-glutamatergic drugs, perampanel, an AMPA-receptor antagonist, and dextromethorphan, an NMDA-receptor antagonist, and nimodipine, an L-type voltage-gated calcium channel blocker in 16 healthy adults in a pseudorandomized, double-blinded, placebo-controlled, crossover design. Single-pulse TM…
Dual lumen microcatheters for recanalisation of chronic total occlusions: A EuroCTO Club expert panel report
2021
Dual lumen microcatheters (DLMC) have become indispensable tools in the setting of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Other than allowing preservation and treatment of bifurcated coronary branches within or in the proximity of the CTO-body, they enable the use of modified parallel wiring, antegrade dissection and re-entry, collateral selection and retrograde negotiation of the distal CTO-cap. This Euro-CTO consensus document describes current DLMCs and suggests a practical guide to anatomies and techniques in which these devices are applicable.
The Covid-19 containment effects of public health measures - A spatial difference-in-differences approach
2020
AbstractSince mid-March 2020 the Federal and state governments in Germany agreed on comprehensive public health measures to curb the spread of SARS-CoV-2 infections leading to the Covid-19 disease. We study the containment effects of these policy interventions on the progression of the pandemic in the first containment phase in spring 2020 before the easing of restrictions may become effective by the end of April. To exploit both the temporal and spatial dimension in the dissemination of the virus, we conduct a spatial panel data analysis for German NUTS-3 regions. Specifically, we employ a spatial difference-in-differences approach to identify the effects of six compound sets of public hea…
Adherence to medical follow‐up recommendations reduces hospital admissions: Evidence from diabetic patients in France
2020
International audience; The aim of this study was to document the extent to which diabetic patients who adhered to required medical follow‐ups in France experienced reduced hospital admissions over time. The main assumption was that enhanced monitoring and follow‐up of diabetic patients in the primary care setting could be a substitute for hospital use. Using longitudinal claim data of diabetic patients between 2010 and 2015 from MGEN, a leading mutuelle insurance company in France, we estimated a dynamic logit model with lagged measures of the quality of adherence to eight medical follow‐up recommendations. This model allowed us to disentangle follow‐up care in hospitals from other forms o…
Familial hypercholesterolaemia is underdiagnosed and undertreated in the general population: guidance for clinicians to prevent coronary heart diseas…
2013
AIMS: The first aim was to critically evaluate the extent to which familial hypercholesterolaemia (FH) is underdiagnosed and undertreated. The second aim was to provide guidance for screening and treatment of FH, in order to prevent coronary heart disease (CHD).METHODS AND RESULTS: Of the theoretical estimated prevalence of 1/500 for heterozygous FH, <1% are diagnosed in most countries. Recently, direct screening in a Northern European general population diagnosed approximately 1/200 with heterozygous FH. All reported studies document failure to achieve recommended LDL cholesterol targets in a large proportion of individuals with FH, and up to 13-fold increased risk of CHD. Based on prev…
Pregraduate Training in Emergency Medicine
1992
AbstractA panel session on undergraduate education in Emergency Medicine from a worldwide perspective was conducted at the Seventh World Congress of Emergency and Disaster Medicine in Montreal, in May, 1991. Desmond Colohan MD, of the University of Toronto (Canada) was the panel moderator. Panel speakers were: Louis Binder MD, Texas Tech University Health Services Center (USA); Wolfgang Dick MD, University of Mainz (Germany); Bernard Nemitz MD, Faculty de Medicine d'Ameins (France); Yoel Donchin MD, Hadassa Medical Organization (Israel); and Noriyoshi Ohashi MD, Tsukuba Medical Center (Japan).
Perampanel and Visuospatial Skills in Children With Epilepsy
2021
Introduction: Perampanel (PER) is a non-competitive AMPA glutamate receptor antagonist approved for focal and generalized seizures as add-on therapy. PER does not seem to negatively affect the cognitive profile in children and adolescents, but its influence on visuospatial abilities is still to be assessed. The aim of our study was to assess visuospatial skills through a standardized neuropsychological evaluation in adolescents taking PER for 12 months.Methods: Our sample included 46 adolescents aged 12–18 years with focal and generalized drug-resistant epilepsy already in therapy with one or two antiseizure medications. Changes in visuospatial perception and memory were assessed by the Rey…
