Get PDFA Molecular-Informed Species Inventory of the Order Ceramiales (Rhodophyta) in the Narragansett Bay Area (Rhode Island and Massachusetts), USA
Get PDFNarragansett Bay is an estuarine system in the western North Atlantic Ocean that harbors a diverse marine flora, providing structure, habitat, and food for native biodiversity. This area has been the center of numerous environmental, biological, ecological, and oceanographic studies; however, marine macroalgae have not been extensively examined using modern molecular methods. Here, we document the biodiversity of the red algal order Ceramiales based on DNA sequence comparisons of the 3′ end of the RuBisCo large subunit (rbcL-3P) and the universal plastid amplicon (UPA). Thirty-seven distinct species of this order were identified and validated with molecular data, including five new species reports and at least one new report of an introduced species, Antithamnionella spirographidis, in the vicinity of Narraganset Bay. Novel sequence data were generated for numerous species, and it was discovered that the UPA marker, which has been less frequently used in red algal floristics, revealed an identical inventory of ceramialean algae as the rbcL-3P marker. Thus, the shorter length of the UPA marker holds promise for DNA metabarcoding studies that seek to elucidate biodiversity across algal phyla
Are Industry Returns Informative about Other Industries and Fundamentals?
Get PDFThis paper examines the information content of selected US industries focusing on the dynamic linkages among these industries, the stock market and a number of fundamental variables. The period of investigation spans from January 1960 to December 2021. The empirical strategy includes several methodologies such as regressions, vector autoregressions and volatility models. The idea is to investigate the dynamic linkages among these series at both the mean and the volatility levels. The results point to significant industry returns’ explanatory power for many predictors of economic activity including the stock market. Further, time-varying analysis of the linkages among the industries and the stock market’s returns reveal that certain industries such as Oil and Financials provide consistent information leadership over other industries and across decades. Further, upon assessing the industry–market return volatility spillovers, it was found that a market risk–return profile may not always be economically significant and timely for investors. Finally, crises, financial or otherwise, affect industries but to differing degrees
Germicidal Ultraviolet (GUV): A Powerful Tool for Improving Indoor Air Quality and Reducing Disease Transmission
Get PDFBar-supported negative curvature hollow-core fiber for low-loss guidance in the near-infrared region
No full textA novel negative curvature hollow-core optical fiber with bar-supported tubular structures is proposed. The five sets of cladding elements improved the transmission in the near-infrared region as low as 0.0014 dB/km with strong single-mode guidance
The Relative Impacts of Peer Disapproval, Parental Disapproval, and Perceptions of Risk on Adolescent Marijuana Use
Get PDFAdolescent drug use has consistently been a concern for researchers and policymakers for decades as its early onset and continued use can lead to a variety of negative life outcomes. Concerns related to marijuana use have emerged in recent years as states have begun to change laws regarding recreational cannabis use. The current study uses data from a cohort of students in Massachusetts to understand how these changes may impact marijuana use. Findings from this study suggest that nearly three years after the first recreational marijuana retail center opened, the protective features of parental norms toward marijuana use may no longer be relevant in protecting young people from early experimentation with drugs. Policy implications are discussed
