Many studies on the fertility differential by religion have considered both Catholics and Protestants to be equally homogenous groups. Contrary to these studies, we contend that Protestant fertility must be studied in the context of heterogeneous groups. Specifically, conservative Protestantism, with its beliefs about artificial birth control mirroring Catholic teaching, should be examined separately from other Protestant traditions. Using data from the General Social Survey we find that conservative Protestants and Catholics had about the same level of fertility, while mainline Protestants have a fertility rate that is significantly lower than that of Catholics. We also examine the changes in these differences over time.
immediate negative sanctions (receiving criticism from the congregation) significantly increase the amount of money given by respondents to religious organizations. Our results also indicate that sanctions promised in the future (belief in Heaven and belief in Hell) have little to no effect on religious giving. Furthermore, we find that immediate positive and negative sanctions as well as future negative sanctions predict greater participation in religious organizations, while future positive sanctions show no such effects. The results are discussed in the context of the emerging trend of waning religious involvement in the contemporary United States.
Food- and water-borne bacteria are a major health concern worldwide. Current detection methods are time-consuming and require sophisticated equipment that is not always readily available. However, new techniques based on nanotechnology are under development that will result in a new generation of sensors. In this experiment, liposomes are synthesized that consist of a bacteria-sensing structure on the outer surface and a polydiacetylene signal transducer. The sensor gives a dramatic blue-to-red color change in the presence of lipopolysaccarides (LPS) extracted from bacteria cell walls. The treatment of slightly different liposomes under multiple analysis conditions may be used to create a sensor array (an optical tongue) that is able to distinguish between LPS derived from different Gram-negative bacteria. The experiment introduces students to concepts of self-assembly, supramolecular synthesis, biosensor design, and to the basic structure of bacteria cell walls. It also readily lends itself to expansion as an investigative-learning experience through student-led modification of the liposome structure.
Acute macular neuroretinopathy (AMN) commonly affects young to middle-aged females and is considered a relatively rare retinal disease, and the etiology is complex. Advances in multimodal imaging provide a better characterization of retinal disorders and have helped identify that one of the etiologies of AMN is microvascular in nature. This case is clinically relevant as it adds to the literature that the pathophysiology of AMN is vascular-driven. Our case is a 24-year-old Black female with no past medical history, the only medication she was taking was an oral contraceptive pill, who presented to the emergency room with a 24-hour history of left central field vision loss and endorsed a recent upper respiratory tract infection preceding the acute vision loss. It was subsequently found on admission that the patient tested positive for and had a SARS-CoV-2 infection. A retina specialist performed optical coherence tomography (OCT), which showed disruption in the outer segment junction, including the ellipsoid zone and outer plexiform. The use of multimodal imaging like OCT helped confirm AMN; therefore, prompt examination by ophthalmology is critical to confirm a correct diagnosis. This patient’s vision improved and remained stable five months later. This case demonstrates that, like other viruses, SARS-CoV-2 has the potential to cause retinal disease complications such as AMN. These findings reinforce and add to the current literature that SARS-CoV-2 can cause multiple-organ system dysfunction at a vascular level through immune-mediated pathways.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
