Alpha-adrenergic drugs in retrograde ejaculation.

1974

6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.

The contribution of dynamic marketing capabilities to service innovation and performance

2015

Innovation can become a sustainable competitive advantage for service firms. However, there is lack of empirical research on how marketing capabilities support innovation. This study differentiates between operational and dynamic marketing capabilities, the latter related to strategic marketing, marketing planning and market knowledge skills. Based on a sample of 152 service firms, the results show that operational marketing capabilities influence on those dynamic marketing capabilities. Strategic marketing and marketing planning capabilities impact positively on firm's performance while market knowledge capabilities impact positively on service innovation.

On the signaling effect of reward-based crowdfunding: (When) do later stage venture capitalists rely more on the crowd than their peers?

2021

Abstract Venture capitalists (VCs) make only a small number of investments and are more likely to invest in ventures where other VCs have invested previously. As such, valuable opportunities may be forgone if they are not funded by VCs in the first place. We demonstrate how crowdfunding (CF) can remedy this concern. Using a sample of new technology-based ventures, we reveal that ventures initially funded through reward-based CF can be even more likely than those initially backed by VCs in attracting follow-up funds from VCs. This happens when ventures originally funded via reward-based CF complement the certification they derive from CF with patents and a founding team with a track record o…

Localizzazione ottimale degli stalli per il parcheggio delle biciclette: il caso studio della città di Palermo - Optimal location for bike parking lo…

2015

The lack of parking spaces for bicycles is one of the main issues that many cities face. A proper planning of a bike station network is necessary in order to optimize the whole urban system and the transport supply. In this work a step-by-step analysis is proposed to find the best location for the bicycle lots in the old town of Palermo. The optimization method includes the use of both a Set Covering Model and a Maximum Coverage Location Problem. The dataset for the simulations was collected by direct and indirect surveys on the population and implemented into Open source GIS software. In particular, data on the destinations, times and distances covered by the bicycles’ users were included.…

Markovian Connection, Curvature and Weitzenböck Formula on Riemannian Path Spaces

2001

Abstract We shall consider on a Riemannian path space P m o ( M ) the Cruzeiro–Malliavin's Markovian connection. The Laplace operator will be defined as the divergence of the gradient. We shall compute explicitly the associated curvature tensor. A Weitzenbock formula will be established. To this end, we shall introduce an “inner product” between the tangent processes and simple vector fields.

¿Son los bancos empresas especiales a los efectos de su regulación?

2004

Victor.E.Barrios@uv.es El poder coercitivo del Estado en el control y supervisión de las empresas alcanza uno de sus máximos exponentes en el caso de los bancos, sujetos a una regulación prudencial específica, de dimensión desconocida en otros sectores. La naturaleza especial de estas empresas, su potencial fragilidad y su estrecha vinculación con el crecimiento económico parecen argumentos suficientes para justificar este resultado, si bien la confirmación de esta hipótesis será uno de los objetivos de este trabajo. En una segunda etapa, una vez hemos confirmado que los bancos pueden ser empresas candidatas para una regulación específica, comprobaremos que efectivamente los principios que …

AISF position paper on liver transplantation and pregnancy: Women in Hepatology Group, Italian Association for the Study of the Liver (AISF)

2016

After the first successful pregnancy in a liver transplant recipient in 1978, much evidence has accumulated on the course, outcomes and management strategies of pregnancy following liver transplantation. Generally, liver transplantation restores sexual function and fertility as early as a few months after transplant. Considering that one third of all liver transplant recipients are women, that approximately one-third of them are of reproductive age (18-49 years), and that 15% of female liver transplant recipients are paediatric patients who have a >70% probability of reaching reproductive age, the issue of pregnancy after liver transplantation is rather relevant, and obstetricians, paedi…

A critical review on supply chain risk – Definition, measure and modeling

2015

Abstract Economic systems are increasingly prone to complexity and uncertainty. Therefore, making well-informed decisions requires risk analysis, control and mitigation. In some areas such as finance, insurance, crisis management and health care, the importance of considering risk is largely acknowledged and well-elaborated, yet rather heterogeneous concepts and approaches for risk management have been developed. The increased frequency and the severe consequences of past supply chain disruptions have resulted in an increasing interest in risk. This development has led to the adoption of the risk concepts, terminologies and methods from related fields. In this paper, existing approaches for…

Uncertain outcome presentations bias decisions: experimental evidence from Finland and Italy

2016

Even in their everyday lives people are expected to make difficult decisions objectively and rationally, no matter how complex or uncertain the situation. In this research, we study how the format of presentation and the amount of presented information concerning risky events influence the decision-making process, and the propensity to take risk in decision makers. The results of an exploratory survey conducted in Finland and in Italy suggest that decision-making behavior changes according to the way the information is presented. We provide experimental evidence that different representations of expected outcomes create distinct cognitive biases and as a result affect the decisions made. Th…
