Did Globalization Lead to Segmentation? Identifying Cross-Country Growth Regimes in the Long-Run
Economic historians have stressed that income convergence was a key feature of the 'OECD-club' and that globalization was among the accelerating forces of this process in the long-run. This view has however been challenged, since it suffers from an ad hoc selection of countries. In the paper, a mixture model is applied to a sample of 64 countries to endogenously analyze the cross-country growth behavior over the period 1870-2003. Results show that growth patterns were segmented in two worldwide regimes, the fi?rst one being characterized by convergence, and the other one denoted by divergence. Interestingly, when three historical epochs are analyzed separately (1870-1913; 1913-1950; and 1950-2003), the dynamics which come to dominate over the whole period emerged only during the post-1950 years. In contrast, the First Global Wave was marked by global divergence. Therefore, history does not provide unambiguous evidence about globalization and convergence.globalization; economic growth; income convergence; multiple regimes; mixture models
Citation Success: Evidence from Economic History Journal Publications
This study examines the determinants of citation success among authors who recently published their work in economic history journals. We find that full professors, authors from non-economic history departments, and authors working in Anglo-Saxon countries are all more likely to get cited than others whereas affiliation at a top-ranked university has no seeming effect. A number of bibliometric features like article length and number of co-authors also matter for citation success. Our most novel finding is that active diffusion of one’s research, e.g., academic presentations (at conferences, workshops or seminars) or online publication of working papers, has a first-order impact on subsequent citation success.Bibliometrics; Citation Analysis; Citation Success; Economic History; Scientometrics; Poisson Regression
Ranking Economic History Journals: A Citation-Based Impact-Adjusted Analysis
This study ranks - for the first time - 12 international academic journals that have economic history as their main topic. The ranking is based on data collected for the year 2007. Journals are ranked using standard citation analysis where we adjust for age, size and self-citation of journals. We also compare the leading economic history journals with the leading journals in economics in order to measure the influence on economics of economic history, and vice versa. With a few exceptions, our results confirm the general idea about what economic history journals are the most influential for economic history, and that, although economic history is quite independent from economics as a whole, knowledge exchange between the two fields is indeed going on.economic history; journal ranking; citation analysis; scientometrics; impact factor
Anti-transpirant effects on vine physiology, berry and wine composition of cv. Aglianico (Vitis vinifera L.) Grown in South Italy
In viticulture, global warming requires reconsideration of current production models. At the base of this need there are some emerging phenomena: modification of phenological phases; acceleration of the maturation process of grapes, with significant increases in the concentration of sugar musts; decoupling between technological grape maturity and phenolic maturity. The aim of our study was to evaluate the effect of a natural anti-transpirant on grapevine physiology, berry, and wine composition of Aglianico cultivar. For two years, Aglianico vines were treated at veraison with the anti-transpirant Vapor Gard and compared with a control sprayed with only water. A bunch thinning was also applied to both treatments. The effectiveness of Vapor Gard were assessed through measurements of net photosynthesis and transpiration and analyzing the vegetative, productive and qualitative parameters. The results demonstrate that the application of antitranspirant reduced assimilation and transpiration rate, stomatal conductance, berry sugar accumulation, and wine alcohol content. No significant differences between treatments were observed for other berry and wine compositional parameters. This method may be a useful tool to reduce berry sugar content and to produce wines with a lower alcohol content
Citation Success: Evidence from Economic History Journal Publications
This study analyses determinants of citation success among authors publishing in economic history journals. Bibliometric features, like article length and number of authors, are positively correlated with the citation rate up to a certain point. Remarkably, publishing in top-ranked journals hardly affects citations. In regard to author-specific characteristics, male authors, full professors and authors working economics or history departments, and authors employed in Anglo-Saxon countries, are more likely to get cited than others. As a ‘shortcut’ to citation success, we find that research diffusion, measured by number of presentations and people mentioned in acknowledgement, boosts the citation rate.bibliometrics; citation analysis; citation success; economic history; scientometrics; Poisson regression
Did Globalization Drive Convergence? Identifying Cross-Country Growth Regimes in the Long Run
This paper is the fi?rst to apply a fi?nite mixture model to a sample of 64 nations to endogenously analyze the cross-country growth behavior over the period 1870-2003. Results show that growth patterns were segmented in two worldwide regimes, the one characterized by convergence in per capita income, and the other by divergence. Interestingly, when three historical epochs are distinctly analyzed, in order to investigate the empirical link between globalization and convergence, the dynamics which dominated over the whole period seem to have emerged only during the post-1950 years. In contrast, the First Global Wave was marked by persistent heterogeneities.Globalization; Economic growth; Income convergence; Multiple regimes; Mixture models
Institutions and geography: Empirical test of spatial growth models for European regions
This article provides an empirical assessment of the growth experiences of European regions, during the period 1991-2004, by taking into account the spatial effects due to both institutions and geography. These effects have been modeled by means of specific controls and by using a non-conventional spatial weight matrix. Results favour a model dealing with substantive spatial externalities. Within this framework, the country-specific institutions are strongly and positively related to the regional productivity’s growth rate. In addition, the geo-institutional proximity increases the spatial dependence of the regional output per worker and raises the speed of convergence. By contrast, the pure geographical metrics is underperforming, while underestimating the convergence dynamics.Regional growth, income convergence, institutions, geography, spatial effects.
Variations of peel essential oils during fruit ripening in four lemon (Citrus limon (L.) Burm. F.) cultivars
Lemon processing procedures yield a significant amount of waste as peels, which are 57% of processed lemons and represent a possible source of bioactive compounds (essential oils, EOs). EOs were extracted from lemon fruits belonging to four cultivars harvested at four different sampling times (25 October, 23 November, 20 December, 1 February), characterized, and quantified through gas chromatography-mass spectrometry
Comparative Bioavailability Study of Two 81 mg Coated Tablet Formulations of Acetylsalicylic Acid in Fasting Healthy Volunteers
Introduction: Low-dose acetylsalicylic acid is used as antithrombotic agent and the enteric-coated formulations are widely used to minimize the gastrointestinal side effects.
Aim: To compare the bioavailability of two acetylsalicylic acid formulations (Ecasil-81®, 81 mg coated tablet) in fasting healthy volunteers.
Methods: Healthy volunteers (n=16) were recruited to a monocentric, open label, randomized, two-way crossover pharmacokinetic study, with seven days washout period between the treatments. They received a single 81 mg oral dose of a test (new formulation) or a standard reference formulation of acetylsalicylic acid (Ecasil-81®) after about 8 h fasting. Blood samples were collected over a period of 36 h. The salicylic acid plasma concentration was evaluated by high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS). Noncompartmental pharmacokinetic analysis was performed using the WinNonlin program.
Results: The maximum plasma concentration (Cmax) of salicylic acid was 5433 and 5719 ng/mL reached in 3.66 and 4.02 h (tmax) for the test and the reference formulation, respectively. The 90% confidence interval of the ratios of geometric means of Cmax and area under curve of plasma concentration until the last concentration observed (AUC0- last) were within the interval 80-125%.
Conclusion: The new acetylsalicylic acid formulation has a bioavailability equivalent to the reference formulation for the rate and the extent of absorption
