A Study of the Joint Patterns in Gently Dipping Sedimentary Rocks of South-Central Kansas

The two most prominent joint sets in Butler and Cowley counties and in parts of Greenwood, Chase and Marion counties, Kans., have consistent regional orientation regardless of the age of the rocks containing them. Set I strikes northeast, whereas Set II strikes northwest. The angle between the sets averages 93°. Both sets occur either as single or compound groups. Set III joints cluster around the two major sets and are subordinate in number with less consistent orientation. Most of the joints studied are vertical. On the basis of physical characteristics, joints of Sets I and II are shear joints, whereas Set III joints are tension joints. The joints are believed to have formed after the major development of the anticlinal folds in the region but may have developed simultaneously with later readjustments of the folds. The joints show no relation to subsurface faults but are closely aligned with the "en echelon" belt of faults of Oklahoma. Because most joints are vertical to the bedding, the jointing and regional tilting may be contemporaneous products of the same deformational period. The age of the joints is determined to be between post-lower Permian and pre-lower Cretaceous time. The joints may have formed as a result of north-West, horizontal, compressive forces generated by wrench-fault tectonics during initial Ouachita Mountain uplift. These forces were coupled with an opposite force, possibly from the Rocky Mountain region. Evidence shows that at least two separate but inter-related joint systems may exist in the midcontinent region

Ephemeral Puerto Rican Placemaking in the Rural Midwest

In this essay, I examine Puerto Rican placemaking from the vantage point of rural-to-rural migration between a central region in Puerto Rico and the U.S. Midwest. I focus on the towns of Jayuya, Puerto Rico, and Rantoul, Ilinois, due to the 2007 labor recruitment that shaped the towns’ future relationality. Specifically, I explore two independent experiences—2007 labor and leisure and 2017 solidarity action posthurricanes and earthquakes in Puerto Rico and Mexico—that show how placemaking can vary between tensions and ties, over time, and by different people experiencing broader ethnoracial dynamics across factories, churches, and social space. Ultimately, I emphasize the hyperlocal Brown and Black experiences in local, rural spaces that form ephemeral, nonrepetitive placemaking practices in which people learn themselves and places anew

Mercury’s Shadow: The Pharmaceutical Sources of Hysteria

This essay reconsiders the nineteenth-century epidemic of hysteria in the context of common pharmaceutical practice. Examining the health records of industrial workers, Civil War soldiers, and such prominent figures as Abraham Lincoln, Louisa May Alcott, and Harriet Beecher Stowe, this essay argues that hysteria in its distinctive nineteenth-century manifestation was the result of mercury poisoning. Physicians throughout the nineteenth century commonly prescribed mercury treatments for everything from teething and diaper rash to dysentery and syphilis. Nineteenth-century Americans were habitually exposed to mercury, and yet physicians did not recognize the symptoms of chronic mercury poisoning, which included numbness and paralysis of hands and limbs, tremors, seizures, and difficulties speaking, seeing, and walking. The symptoms of mercury poisoning correspond directly with the symptoms of hysteria, and even Sigmund Freud’s famous case histories of hysteria attest to the presence of mercury in his patients’ medical backgrounds. It is no accident that hysteria disappeared in the early twentieth century, just as antibiotics and more effective treatments emerged, but hysteria’s legacies nonetheless endure in recent environmental catastrophes and episodes of pharmaceutical malpractice. &nbsp

Features in Kansas cyclothems seen by high-resolution seismology

Accurate quantitative modeling of stratal sequences requires verification of model results by means of comparisons with known stratigraphic intervals, and in many cases seismic data provide the best or only means toward that end. In eastern Kansas the scale of variability within Middle and Upper Pennsylvanian units is of the order of meters. Unraveling the stratigraphy and thereby verifying models at such a scale requires high-resolution seismic data. Middle and Upper Pennsylvanian cyclic sequences (cyclothems) are seen as just a few wiggles on standard petroleum exploration reflection seismogram sections with frequency responses of <80 Hz. For instance, the Kansas City and Lansing Groups cannot be distinguished. However, the use of high-resolution reflection seismology, with frequencies up to 500 Hz, allows the detection of thin-bed members of the individual groups and formations to approximately 2-m (7-ft) thickness. Geologic cyclicity and reflection seismology harmonize, and carbonate units are seen as peaks and siliciclastic units (mostly shales) as troughs. Seismic response becomes sensitive to phenomena such as the presence of intrabed sandstone lenses in the shales and the surface roughness (diffusivity) of lithologic interfaces. Complex trace analysis aids the interpretation of bed thickness and the nature and continuity of geologic boundaries. Reflection strength helps determine which geologic boundaries form strong reflectors and therefore have clean, flat interfaces. Instantaneous phase complements reflection strength by showing strong trace-to-trace coherence and by emphasizing stratal truncations, indicating intrabed structure and sandstone channel presence. Instantaneous frequency indicates (1) intrabed structure and sandstone channel presence when it displays a chaotic pattern and (2) the dominant frequency of the reflector response when coherent. Dominant frequency of the reflector response is frequently useful in determining bed thickness

Competencies for Community Psychology Practice in Spain: Standards, Quality and Challenges in Social Intervention

In this paper, competencies for community psychology practice are examined within the Spanish context, based on the experience of a Master in Psychology of Social and Community Intervention in the University of Seville. The list of competencies was developed specifically for monitoring the practicum of master students, and it was developed in a portfolio format, following the usual pattern in the European accreditation process "EuroPsy," designed by the professional associations of psychology. The portfolio consists of 29 generic professional competencies, grouped in seven blocks: needs specification, evaluation, product development and services, psychological intervention, assessment of psychological interventions, communication, and enabling competencies. At the national level, we analyze the impact that the new system of training and accreditation of psychologists who perform health activities is having on the professional recognition and the role of community psychologists. At the international level, we compare the EuroPsy proposal with the list of 18 competences proposed by Dalton and Wolfe (2012) and approved by the Society for Community Research and Action, APA Division 27. Finally, we discuss the advantages and limitations of a generic model of competency assessment, focused on the professional practice of psychology

Modeling of tidal rhythmites using modern tidal periodicities and implications for short-term sedimentation rates

Within Carboniferous strata cyclical variations in lamina thickness have a modern counterpart in tidal systems. These lamina thickness cycles can be equated to several types of neap-spring periodicities and longer-term seasonal periods. The various hierarchies of cycles within the ancient tidal deposits can be modeled using modern tidal station data. This type of fine-scale modeling indicates how the various tide-producing parameters of the earth-moon-sun system can be encoded in ancient tidal deposits. Based on relationships of lamina cycles to known tidal periods, inferred cycle periods indicate that such sections underwent rapid, localized, vertical accretion. Large discrepancies are evident when such short-term rates are compared to long-term rates of formation-level accumulation. Such comparisons indicate that long-term accumulation rates are many orders of magnitude slower than actual rates of deposition produced by tidal sedimentation
