Seed ovoid, compressed, about 5 mm long, 3 mm wide; testa yellowish, verruculouse. Etymology The species epithet is obtained from the province name, Mazandaran, located in northern Iran, where the new species is found for the first time. Phytochoria:—In shrublands between Hyrcanian and Irano-Turanian provinces to Irano-Turanian province in north and northeast of Iran (Zohary 1973, Takhtajan 1986). Phenology:—Flowering occurs in late April to early May and, the fruit matures in late June. Distribution: — Prunus mazandaranica has been collected from several localities in the central to eastern parts of Alborz mountain in the transitional zone between Hyrcanian and Irano-Turanian regions in north and northeast of Iran. This species is observed in sympatry with P. microcarpa subsp. microcarpa in most the occupied areas, whereas P. paradoxa and P. yazdiana are endemic species found only in one small population at Durak fountain in Lorestan province (W Iran) and Damgahan valleys in Yazd Province (C Iran), respectively. Moreover, P. mazandaranica is seen in small patches with Berberis integerrima Bunge, Rosa canina L., Crataegus atrosanguinea Pojark. Rhamnus cathartica L., Prunus divaricata Ledeb.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Essays in Economics of Artificial Intelligence
No full textThis thesis embodies three chapters on the economics and applications of artificial intelligence (AI). The first chapter explores the economic underpinnings of open-source contributions in AI by for-profit companies, focusing on large language models (LLMs). Three main findings emerge: (1) LLMs align well with the R&D portfolios of diverse technologically advanced firms, (2) models developed by large technology companies are more likely to be open-sourced, and (3) open-sourcing advanced LLMs enhances research-related activities. A theoretical framework analyzes the factors influencing a firm's decision to open-source, suggesting an inverted-U-shaped relationship between open-sourcing propensity and the firm's share of LLM-compatible applications. The second chapter addresses the debate on the moderation of toxic speech on social media and its impact on the plurality of online discourse. A new methodology is proposed and validated to measure plurality based on the semantic variance of online content, using text embeddings from computational linguistics. Applying this measure to a dataset of 10 million US Tweets, it is found that removing toxic content reduces the plurality of online discourse. Crucially, the reduction in plurality is attributed not to the toxic language itself, but to the removal of meaningful content. The third chapter proposes a novel method for estimating biases at the micro-level in contexts with multiple bilateral interactions, where individual preferences and correlated characteristics complicate analysis. The method employs Collaborative Filtering in an `honest' design to extract preferences and characteristics, separating self-induced outcomes from the constructed embeddings of interacting units
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
