The incubation process for the creation of viable firms: the case of ARCA Consortium

The aim of this study is to demonstrate that academic incubators play a key role in firm viability. This study develops a new analytic systemic framework that reveals the processes and factors that determine the effectiveness of the incubation process supported by university incubators. We analyse the effectiveness of the incubation process in the incubator of the ARCA Consortium by means of a single case study with an embedded design. In this study, adopting a systemic perspective, we shift the focus from the firm to the context, shedding light on the systemic actions that create the prerequisite conditions for the achievement of the firms\u2019 viability

Mitigation of fugitive dust impact arising from BR dry disposal

The development of international policies about environmental defense has enforced some major modifications in the management of industrial tailings. As regards the disposal of the residue deriving from the bauxite processing (BR) in the alumina industry, national and international regulations have encouraged the evolution from wet to dry disposal techniques. However, such a change in the storage practices poses a major concern due to the potential increase of the atmospheric impact in the surrounding areas, due to the emissions of Particulate Matter (PM) generated both by the BR disposal activities and by the wind erosion over the dried surfaces of the landfill. The article analyses the effect of the impact mitigation measures typically adopted to control PM emissions with reference to a major red mud basin located in the southwest of Sardinia (Italy). The PM dispersion models performed with the CALPUFF code (US EPA) allowed, for the case study under consideration, the estimate of the improvement provided by moistening the dry surfaces and reducing the total length travelled par year by the machinery involved in material handling, transportation and disposal

PM emissions from a BR basin and impact assessment on air quality

The article deals with the emission of fugitive dust from a major BR (Bauxite Residue) basin located in the south-west of Sardinia, where the prospect of a change in the storage practices is likely to cause the increase of PM (Particulate Matter) pollution in the surrounding region. In fact, other natural and anthropic sources already provide a variable contribution in terms of airborne dust concentration in the same territory. In accordance with the procedures established by the Directive 2011/92 (EIA Directive - Environmental Impact Assessment), the data recorded by a monitoring network located in the SulcisIglesiente sub-region has been taken into consideration in order to define the ante-operam condition of the potential impact area. The additional contribution of the red mud basin has been simulated with the atmospheric dispersion model proposed by US EPA (Environmental Protection Agency). The expected whole concentration of the PM10, which includes both the pre-existing sources and the additional contribution of the red mud basin, has been estimated and compared with the limit values established by the Directive 2008/50/EC (Ambient air quality and cleaner air for Europe)

Lipid and lipoprotein profile changes in dairy cows in response to late pregnancy and the early postpartum period

Abstract. In dairy cows the peripartum period involves endocrine and metabolic changes to compensate for the increased energy requirement aggravated by reduced feed intake. Cows adjust to the resulting negative energy balance with the mobilization of lipids from adipose tissue that, if excessive, could lead to many transition disorders compromising the offspring's growth and well-being. The aim of this study was to evaluate the dynamic changes in serum lipid and lipoprotein profiles in five dairy cows during the peripartum period. For each cow body condition score (BCS) and body weight (BW) measurements as well as blood sampling was carried out 60, 30 and 15 days before calving (−60, −30 and −15BC), at calving day (C) and on days 15, 30 and 60 after calving (+15, +30 and +60AC). Blood samples were tested for serum total lipids, phospholipids, triglycerides, very low-density lipoproteins (VLDLs), total cholesterol (Total-Chol), high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs). One-way repeated measures analysis of variance (ANOVA) was applied to determine the effect of the peripartum period on the studied parameters in cows. A statistically significant effect of the peripartum period (P &amp;lt; 0.05) was found in the values of BCS, BW and all serum lipid and lipoprotein indices measured in cows. The changes observed in lipid indices of peripartum cows could be due to the start of milking and the increase in energy consumption in the body, confirming that metabolic adjustments occur as cows move from the gestation to the lactation period.</p

an analysis of recent research on venture capital networks

Purpose – this paper examines recent trends in venture capital network research. Network analysis is a useful approach for analyzing inter-organizational networks, especially for venture capitalists, which are characterized by plenty of connections. Although important steps ahead have been made, several research questions are still unanswered. Research methodology – this brief review analyses deeply three papers which are representative of the novel scientific literature in this field. Scrutinizing these works, I identify their points of strength and weaknesses, in order to understand how to pave the way for further research. Findings – this paper shows that the study of network weak ties and the role of risk management strategies are promising areas for pushing the frontiers of research on venture capital networks. Research limitations – although less recent papers are not considered in this analysis, the in-depth discussion of the latest research provides interesting insights and advice for scholars willing to do research on this field of studies. Practical implications – extending our knowledge on this topic is crucial for understanding the best strategic decisions venture capitalists should take when operating within an inter-organizational network. Originality/Value – this paper critically analyses steam of literature which is important from both scientific and managerial viewpoints. Furthermore, it poses questions to be addressed by future research

Adherence issues related to sublingual immunotherapy as perceived by allergists

Objectives: Sublingual immunotherapy (SLIT) is a viable alternative to subcutaneous immunotherapy to treat allergic rhinitis and asthma, and is widely used in clinical practice in many European countries. The clinical efficacy of SLIT has been established in a number of clinical trials and meta-analyses. However, because SLIT is self-administered by patients without medical supervision, the degree of patient adherence with treatment is still a concern. The objective of this study was to evaluate the perception by allergists of issues related to SLIT adherence. Methods: We performed a questionnaire-based survey of 296 Italian allergists, based on the adherence issues known from previous studies. The perception of importance of each item was assessed by a VAS scale ranging from 0 to 10. Results: Patient perception of clinical efficacy was considered the most important factor (ranked 1 by 54% of allergists), followed by the possibility of reimbursement (ranked 1 by 34%), and by the absence of side effects (ranked 1 by 21%). Patient education, regular follow-up, and ease of use of SLIT were ranked first by less than 20% of allergists. Conclusion: These findings indicate that clinical efficacy, cost, and side effects are perceived as the major issues influencing patient adherence to SLIT, and that further improvement of adherence is likely to be achieved by improving the patient information provided by prescribers. © 2010 Scurati et al, publisher and licensee Dove Medical Press Ltd
