Seismically active structural lineaments in south-central Alaska as seen on ERTS-1 imagery

The author has identified the following significant results. A mosaic of south-central Alaska composed of 19 ERTS-1 images, when compared with the seismicity pattern of the area, reveals that the larger earthquakes tend to fall on lineaments which are easily recognizable on the imagery. In most cases, these lineaments have not been mapped as faults. One particular lineament, which was the scene of three earthquakes of magnitude 4 or greater during 1972, passes very close to Anchorage

Some aspects of active tectonism in Alaska as seen on ERTS-1

ERTS-1 imagery is proving to be exceptionally useful in delineating structural features in Alaska which have never been recognized on the ground. Previously unmapped features such as seismically active faults and major structural lineaments are especially evident. Among the more significant results of this investigation is the discovery of an active strand of the Denali fault. The new fault has a history of scattered seismicity and was the scene of a magnitude 4.8 earthquake on October 1, 1972. Perhaps of greater significance is the disclosure of a large scale conjugate fracture system north of the Alaska Range. This fracture system appears to result from compressive stress radiating outward from around the outside of the great bend of the Alaska Range at Mt. McKinley

ERTS-1, earthquakes, and tectonic evolution in Alaska

In comparing seismicity patterns in Alaska with ERTS-1 imagery, it is striking to see the frequency with which earthquake epicenters fall on, or near, lineaments visible on the imagery. Often these lineaments prove to be tectonics faults which have been mapped in the field. But equally as often, existing geologic and tectonic maps show no evidence of these features. The remoteness and inaccessibility of most of Alaska is responsible, in large part, for the inadequacy of the mapping. ERTS-1 imagery is filling a vital need in providing much of the missing information, and is pointing out many areas of potential earthquake hazard. Earthquakes in central and south-central Alaska result when the northeastern corner of the north Pacific lithospheric plate underthrusts the continent. North of Mt. McKinley, the seismicity is continental in nature and of shallow origin, with earthquakes occurring on lineaments, and frequently at intersections of lineaments. The shallower events tend to align themselves with lineaments visible on the imagery

Tectonic mapping in Alaska with ERTS-1 imagery

The author has identified the following significant results. A mosaic of ERTS-1 imagery for a portion of interior Alaska covering approximately 57,000 sq km has proved to be a valuable tool in identifying structural elements previously not recognized. Mapped faults are clearly recognizable and are found to be part of a larger system of faults and lineaments identified on the imagery. A previously unrecognized set of conjugate fractures imply regional compression in a NNW-SSE direction in agreement with known fault dislocations. Earthquakes have a marked tendency to occur at intersections of lineaments seen on the imagery

Environmental transmission of Toxoplasma gondii: Oocysts in water, soil and food

Toxoplasma gondii is a zoonotic protozoan parasite that can cause morbidity and mortality in humans, domestic animals, and terrestrial and aquatic wildlife. The environmentally robust oocyst stage of T. gondii is fundamentally critical to the parasite\u27s success, both in terms of its worldwide distribution as well as the extensive range of infected intermediate hosts. Despite the limited definitive host species (domestic and wild felids), infections have been reported on every continent, and in terrestrial as well as aquatic environments. The remarkable resistance of the oocyst wall enables dissemination of T. gondii through watersheds and ecosystems, and long-term persistence in diverse foods such as shellfish and fresh produce. Here, we review the key attributes of oocyst biophysical properties that confer their ability to disseminate and survive in the environment, as well as the epidemiological dynamics of oocyst sources including domestic and wild felids. This manuscript further provides a comprehensive review of the pathways by which T. gondii oocysts can infect animals and people through the environment, including in contaminated foods, water or soil. We conclude by identifying critical control points for reducing risk of exposure to oocysts as well as opportunities for future synergies and new directions for research aimed at reducing the burden of oocyst-borne toxoplasmosis in humans, domestic animals, and wildlife

From Brown-Peterson to continual distractor via operation span: A SIMPLE account of complex span

Three memory tasks—Brown-Peterson, complex span, and continual distractor—all alternate presentation of a to-be-remembered item and a distractor activity, but each task is associated with a different memory system, short-term memory, working memory, and long-term memory, respectively. SIMPLE, a relative local distinctiveness model, has previously been fit to data from both the Brown-Peterson and continual distractor tasks; here we use the same version of the model to fit data from a complex span task. Despite the many differences between the tasks, including unpredictable list length, SIMPLE fit the data well. Because SIMPLE posits a single memory system, these results constitute yet another demonstration that performance on tasks originally thought to tap different memory systems can be explained without invoking multiple memory systems

Reality and The Handmaid’s Tale

Overview: One of the most terrifying aspects of Margaret Atwood’s dark, dystopian novel, The Handmaid’s Tale, is that the author was inspired by true events. In an interview, Atwood discussed how her writing was heavily inspired by America’s Puritan roots, that is, a society where their laws and gender roles were entirely constructed by rigid religious commandments (Bacci 154). The Handmaid\u27s Tale pulls ideas from the modern patriarchy and sexist culture of America, as well as its roots in Puritanism, to create a dystopia that is void of human rights and entirely androcentric. In this way, Atwood’s novel serves as a warning and an awakening for the modern public, encouraging them to value and protect their human rights. The Handmaid’s Tale provides a chilling insight into the United States sexist foundation that is reflected in modern society today. Modern-day America is still influenced by its founding Puritan ideals and that these partially toxic influences have shaped American culture, especially western gender stereotypes and culture-wide androcentrism. Although the novel is an extremist interpretation, it reminds citizens to continue to explore and understand their inalienable human rights. Author\u27s reflection: My name is Theresa VanWormer and I am an English Major with Minors in Marketing and Communication at St. John Fisher College. Reading and writing has always been an interest of mine, leading me to be a managing editor for the creative writing magazine ANGLES and a writing tutor on campus. I am also the author of “Understanding the Importance of Statues: Symbols of Racism in Modern Society” which was published in the spring 21 edition of The Review. In the Spring of 2022 I will be interning with BOA Publications and hopefully beginning to work on my own creative writing. One day, I hope to write and own my own business as a developmental editor. In my free time I enjoy weight lifting and spending time with my friends and family. I am so grateful for this opportunity, and appreciative of Dr. Uman who led me towards this topic that is so very important to talk about
