A Ricardian Model of New Trade and Location Theory

Ricci, Luca Antonio 세종대학교 국제경제연구소 1997 Journal of Economic Integration Vol.12 No.1

This paper provides a new model of firm's location choices. It integrates a Ricardian model of comparative advantage with the location effects deriving from trade costs, increasing returns to scale, product differentiation, and monopolistic competition. In a two-region, two-differentiated-good, one-factor framework, the regional degree of specialization depends positively on the extent of the comparative advantage in productivity and on the degree of returns to scale; it depends negatively on the magnitude of the trade costs. Hence, the model accommodates high levels of intra-industry trade among countries with similar level of development, as well as high levels of inter-industry trade among countries with different technologies.

Improved 1,3-Propanediol Synthesis from Glycerol by the Robust Lactobacillus reuteri Strain DSM 20016

Ricci, Maria Antonietta,Russo, Annamaria,Pisano, Isabella,Palmieri, Luigi,de Angelis, Maria,Agrimi, Gennaro The Korean Society for Microbiology and Biotechnol 2015 Journal of microbiology and biotechnology Vol.25 No.6

Various Lactobacillus reuteri strains were screened for the ability to convert glycerol to 1,3-propanediol (1,3-PDO) in a glycerol-glucose co-fermentation. Only L. reuteri DSM 20016, a well-known probiotic, was able to efficiently carry out this bioconversion. Several process strategies were employed to improve this process. Co²⁺ addition to the fermentation medium, led to a high product titer (46 g/l) of 1,3-PDO and to improved biomass synthesis. L. reuteri DSM 20016 produced also ca. 3 µg/g of cell dry weight of vitamin B₁₂, conferring an economic value to the biomass produced in the process. Incidentally, we found that L. reuteri displays the highest resistance to Co²⁺ ions ever reported for a microorganism. Two waste materials (crude glycerol from biodiesel industry and spruce hydrolysate from paper industry) alone or in combination were used as feedstocks for the production of 1,3-PDO by L. reuteri DSM 20016. Crude glycerol was efficiently converted into 1,3-PDO although with a lower titer than pure glycerol (33.3 vs. 40.7 g/l). Compared with the fermentation carried out with pure substrates, the 1,3-PDO produced was significantly lower (40.7 vs. 24.2 g/l) using cellulosic hydrolysate and crude glycerol, but strong increases of the maximal biomass produced (2.9 vs 4.3 g/l CDW) and of the glucose consumption rate were found. The results of this study lay the foundation for further investigations to exploit the biotechnological potential of L. reuteri DSM 20016 to produce 1,3-PDO and vitamin B₁₂ using industry byproducts.

The impact of major league baseball on the incidence of operative hand and facial trauma at a level 1 trauma center

Ricci, Joseph A.,Vargas, Christina R.,Ho, Olivia A.,Lin, Samuel J.,Lee, Bernard T. Korean Society of Plastic and Reconstructive Surge 2019 Archives of Plastic Surgery Vol.46 No.3

Background Professional affiliation between medical centers and professional sports teams can be mutually beneficial in the provision of healthcare and marketing strategy. Anecdotal evidence suggests a link between trauma volume and sporting events; however, there is limited data. This study aims to characterize the incidence of operative hand and facial trauma during professional baseball home games. Methods A retrospective review of surgical cases for traumatic hand or facial injuries at a level 1 center between 1999 and 2012 was performed. Demographic information including date of injury, admission status, and operative repair were collected. Patients were grouped based on whether their trauma occurred on the date of a home game. Results Operative hand and facial trauma occurred at a rate of 33.4 injuries per 100 days with home games, compared to 22.2 injuries per 100 days (incidence rate ratios, 1.50; 95% confidence interval, 1.34-1.69). When home games were played, patients were more likely to present as a result of motorcycle accidents (3.1% vs. 1.5%; P=0.04) or bicycle accidents (5.0% vs. 2.6%; P=0.01). Other mechanisms of trauma were not statistically different. There was an increase incidence of injuries during home games in August; weekly variability showed an increased incidence during the weekends. Conclusions There was an increased rate of operative hand and facial injuries on dates with professional home games. The incidence of injuries during home games was higher in the late summer and on the weekends. Further analysis may allow improved resource allocation and strategies for injury prevention and treatment.

In vitro shoot regeneration from leaves of Pyrus communis L. rootstock and cultivars

Ricci Angela,Mezzetti Bruno,Navacchi Oriano,Sabbadini Silvia 한국식물생명공학회 2023 Plant biotechnology reports Vol.17 No.3

The influence of TDZ on adventitious shoot regeneration from leaves of the pear cultivars Conference and Abate Fétel, and the rootstock Farold®87 was investigated. Our main aim was to set up efficient in vitro regeneration protocols for all these pear genotypes by using expanding leaves from elongated shoot cultures as starting plant material. Our best results in terms of percentage of regeneration were achieved by using half-strength Murashige and Skoog basal medium supplemented with 1 μM NAA, combined with 13.5 μM TDZ for Conference (87.3%) and Farold®87 (53.3%), and 9 μM TDZ for Abate Fétel (68%). The impact on leaf organogenesis of the antibiotics timentin, cefotaxime, and carbenicillin, alone or in combination, usually used for the control of Agrobacterium overgrowth, and of kanamycin, commonly used for the selection of putatively transformed plants, were also evaluated to be exploited in future transformation trials. In general, the use of carbenicillin (475 mM), cefotaxime/carbenicillin (210/238 mM) and cefotaxime (630 mM) did not negatively affect the regeneration efficiency of Conference, Abate Fétel and Farold®87, respectively. The use of 4 μM kanamycin should be suitable to select transformed shoots from Abate Fétel and Farold®87 leaves, while a lower concentration or a different selection strategy should be applied for Conference. We report new regeneration and selection protocols usable for the application of new biotechnologies in the genetic improvement of pear cultivars and rootstocks.

BRAND IDENTITY: TRADITION VALUES AS FUTURE ASSET. SALVATORE FERRAGAMO CASE HISTORY

Stefania Ricci,Museo Salvatore Ferragamo 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

The Salvatore Ferragamo Company, founded in 1938 by Salvatore Ferragamo in Florence, is very well known for creation and production of ladies shoes but has a leading role in the whole international luxury market. The company history is ancient and started before 1927, when Salvatore Ferragamo, leaving California, came back to Italy and got to Florence. At that time, Salvatore Ferragamo was already famous in the United States for having created the craftmade footwear for the American actresses. Called ‘The shoemaker of the stars’, Salvatore Ferragamo, very well known at that time, decided to come back to Italy to live and work in Florence , because of its great artistic and handicraft tradition. Since the beginning, the founder was significantly inspired in his work by the local culture. Palazzo Spini-Feroni, which is the company headquarters, is also a symbol of the city history and of the Italian traditional lifestyle. Since the founder’s death in 1960, Salvatore Ferragamo’s wife, Wanda Miletti Ferragamo, and their six children, headed the company. They have extended the Company business getting to complete collections lines either for men and women from “head to toe”, enhancing the distribution in more than 90 countries. The Company is nowadays one of the most important luxury group in the world, resulting from a perfect combination of tradition and innovation, of territorial anchorage and global projection, of handmade craftsmanship and ability to communicate and market-making, of technology and entrepreneurship. The values the founder believed in and the Company heritage, testified by the Museo Salvatore Ferragamo activities, further of being very important at intellectual and social level for Italian culture, represent an important asset of the brand identity. This is the ground on which it has worth to establish the brand’s challenges since the past and it is possible going onwards. This is a perfect example of a “Renaissance” case in fashion and marketing field.

Background/AimsChagasic megacolon is caused by Trypanosoma cruzi, which promotes in several cases, irreversible segmental colonic dilation. This alteration is the major anatomic-clinical disorder, characterized by the enteric nervous system and muscle wall structural damage. Herein, we investigate how T. cruzi -induced progressive colonic structural changes modulate the colonic contractile pattern activity. MethodsWe developed a murine model of T. cruzi-infection that reproduced long-term modifications of the enlarged colon. We evaluated colonic and total intestinal transit time in animals. The patterns of motor response at several time intervals between the acute and chronic phases were evaluated using the organ bath assays. Enteric motor neurons were stimulated by electric field stimulation. The responses were analyzed in the presence of the nicotinic and muscarinic acetylcholine receptor antagonists. Western blot was performed to evaluate the expression of nicotinic and muscarinic receptors. The neurotransmitter expression was analyzed by real-time polymerase chain reaction. ResultsIn the chronic phase of infection, there was decreased intestinal motility associated with decreased amplitude and rhythmicity of intestinal contractility. Pharmacological tests suggested a defective response mediated by acetylcholine receptors. The contractile response induced by acetylcholine was decreased by atropine in the acute phase while the lack of its action in the chronic phase was associated with tissue damage, and decreased expression of choline acetyltransferase, nicotinic subunits of acetylcholine receptors, and neurotransmitters. ConclusionsT. cruzi -induced damage of smooth muscles was accompanied by motility disorders such as decreased intestinal peristalsis and cholinergic system response impairment. This study allows integration of the natural history of Chagasic megacolon motility disorders and opens new perspectives for the design of effective therapeutic.

THE USE OF INTERNATIONAL SHORT-TERM INVESTMENTS BY THE FORTUNE 100

Cecilia Wagner Ricci People&Global Business Association 1997 Global Business and Finance Review Vol.2 No.2

The enormous growth in the number of American firms engaged in international business has increased the research on global financial management tremendously, with the notable exception of transcontinental working capital management. This paper is an attempt to address this issue. The focus of the paper is international marketable securities. This article reports the results of a survey of the Fortune 100. The purpose of the survey was to obtain information on the use of international short-term investments by major American firms, as well as to identify some predictors of such investment. Thus, the importance of this paper lies in its practical relevance to finance practitioners in managing the treasury function, and to academics teaching working capital management or international finance.
