    The purpose of this work is to explore the interactions between occultism and scholarly Egyptology from 1875 to 1930. Within this timeframe, numerous esoteric groups formed that centered their ideologies on conceptions of ancient Egyptian knowledge. In order to legitimize their belief systems based on ancient Egyptian wisdom, esotericists attempted to become authoritative figures on Egypt. This process heavily impacted Western intellectualism not only because occult conceptions of Egypt became increasingly popular, but also because esotericists intruded into academia or attempted to overshadow it. In turn, esotericists and Egyptologists both utilized the influx of new information from Egyptological studies to shape their identities, consolidate their ideologies, and maintain authority on the value of ancient Egyptian knowledge. This thesis follows the Egypt-centered developments of the Freemasons, the Golden Dawn, Aleister Crowley\u27s A∴A∴, the Theosophical Society, the Anthroposophical Society, and the Ancient Mystical Order Rosae Crucis to demonstrate that esotericism evolved simultaneously with academia as a body of knowledge. By examining these fraternal occult groups\u27 interactions with Egyptology, it can be better understood how esotericism has affected Western intellectualism, how ideologies form in response to new information, and the effects of becoming an authority on bodies of knowledge (in particular Egyptological knowledge). In turn, embedded in this work is a challenge to those who have downplayed or overlooked the agency of esotericists in shaping the Western intellectual tradition and preserving the legacy of ancient Egypt

    Background: Concussions comprise 24.8% of the total injuries in high school athletes, putting developing brains at risk for neurocognitive dysfunction. Recent research has been geared towards finding the most effective process for (a) diagnosing, (b) treating and (c) preventing concussions. The most recent data from the Centers for Disease Control and Prevention (CDC) show that 329,290 children were diagnosed with a sports related concussion or traumatic brain injury (TBI) in 2012. Methods: A systematic review of current literature was performed using the Long Island University online library database and Google Scholar. Search terms included: (a) concussion, (b) sports, (c) high school; (d) screening; (e) risk factors; (f) symptoms; (g) complications, and (h) pathophysiology, including the years 2011 to 2018 and in the English language. Results: A concussion is a form of traumatic brain injury resulting in transient neurologic impairment that can resolve spontaneously or have lingering symptoms without structural changes on routine neuroimaging studies. Concussions are the most common injury among high school student-athletes, rising from 9.1% of all injuries in the 2005-2006 school year to 24.8% in the 2016-2017 school year. The overall prevalence is 2.5 concussions per 10,000 athletic exposures (competition or practice). Football has the highest overall rate of concussion with 6.4 per 10,000 athletic exposures, while soccer has the highest rate among girls’ sports with 3.4 per 10,000 athletic exposures. In gender comparable sports, girls have a higher rate of concussion than boys. In general, concussion rates are higher in competition than in practice. Current protocols center around early recognition of symptoms and removal from the field of play. Several screening tools have been developed, including the Sport Concussion Assessment Tool (SCAT-5) to aid in identifying potential concussions on the sideline and initiating proper treatment. Gradual return-to-school and return-to-play criteria have been developed to allow adequate healing time and prevent re-injury. Concussions, especially repetitive, may have long term effects such as (a) post-concussive syndrome, (b) post-traumatic seizures, (c) chronic traumatic encephalopathy (CTE), and (d) decreased neurocognitive function. The CDC offers recommendations for concussion prevention based on each sport, but in general, strict enforcement of the rules and proper protective equipment are key. Conclusions and Recommendations: Prevention and early recognition of symptoms can help reduce the number of concussions as well as long term effects. Athletes should wear all required protective equipment and the equipment should be fully functional. For contact sports, emphasis should be placed on proper form and safe techniques, as well as a limit on the number of full-contact practices per season. These measures can help to prevent concussions from occurring. In addition, officials should be trained to look for concussion symptoms and not hesitate to remove a player from action if they suspect a concussion. Athletes should not be permitted to return to play unless they are cleared by a medical practitioner and there should be stiff penalties for coaches who pressure players into returning prematurely

    Merging the Principles of Occultism and Anarchism

    Get PDF
    Merging the Principles of Occultism and Anarchism is an attempt to pinpoint the correlations between occult and/or esoteric belief systems and political anarchist philosophy. The paper analyzes the works, belief systems and philosophies of Giovanni Pico della Mirandola and Aleister Crowley and extracts the underlying anarchist principles that are embedded within them. This established connection to anarchism through occultism is reinforced by referencing various anarchist works, particularly the works of William Godwin

Ecological Applications, (2021): e02478, https://doi.org/10.1002/eap.2478.We use a simple model of coupled carbon and nitrogen cycles in terrestrial ecosystems to examine how “explicitly representing grazers” vs. “having grazer effects implicitly aggregated in with other biogeochemical processes in the model” alters predicted responses to elevated carbon dioxide and warming. The aggregated approach can affect model predictions because grazer-mediated processes can respond differently to changes in climate compared with the processes with which they are typically aggregated. We use small-mammal grazers in a tundra as an example and find that the typical three-to-four-year cycling frequency is too fast for the effects of cycle peaks and troughs to be fully manifested in the ecosystem biogeochemistry. We conclude that implicitly aggregating the effects of small-mammal grazers with other processes results in an underestimation of ecosystem response to climate change, relative to estimations in which the grazer effects are explicitly represented. The magnitude of this underestimation increases with grazer density. We therefore recommend that grazing effects be incorporated explicitly when applying models of ecosystem response to global change.This work was supported in part by the National Science Foundation under NSF grants 1651722, 1637459, 1603560, 1556772, 1841608 to E.B.R.; 1603777 to N.T.B. and K.L.G.; 1603654 to R.J.R.; 1603760 to L.G.; and 1603677 to J.R.M

E., Naeem, S., Gough, L., McLaren, J. R., Rowe, R. J., Rastetter, E. B., Boelman, N. T., & Griffin, K. L. Herbivore absence can shift dry heath tundra from carbon source to sink during peak growing season. Environmental Research Letters, 16(2), (2021): 024027, https://doi.org/10.1088/1748-9326/abd3d0.In arctic tundra, large and small mammalian herbivores have substantial impacts on the vegetation community and consequently can affect the magnitude of carbon cycling. However, herbivores are often absent from modern carbon cycle models, partly because relatively few field studies focus on herbivore impacts on carbon cycling. Our objectives were to quantify the impact of 21 years of large herbivore and large and small herbivore exclusion on carbon cycling during peak growing season in a dry heath tundra community. When herbivores were excluded, we observed a significantly greater leaf area index as well as greater vascular plant abundance. While we did not observe significant differences in deciduous dwarf shrub abundance across treatments, evergreen dwarf shrub abundance was greater where large and small herbivores were excluded. Both foliose and fruticose lichen abundance were higher in the large herbivore, but not the small and large herbivore exclosures. Net ecosystem exchange (NEE) likewise indicated the highest carbon uptake in the exclosure treatments and lowest uptake in the control (CT), suggesting that herbivory decreased the capacity of dry heath tundra to take up carbon. Moreover, our calculated NEE for average light and temperature conditions for July 2017, when our measurements were taken, indicated that the tundra was a carbon source in CT, but was a carbon sink in both exclosure treatments, indicating removal of grazing pressure can change the carbon balance of dry heath tundra. Collectively, these findings suggest that herbivore absence can lead to changes in plant community structure of dry heath tundra that in turn can increase its capacity to take up carbon.The authors would like to thank Jess Steketee, Austin Roy, Matthew Suchocki, Ruby An, Cody Lane and the Arctic LTER (NSF Grant No. 1637459) for maintaining the long-term herbivore exclosure experiment.

    Development of GCP Ontology for Sharing Crop Information

    Get PDF
    The Generation Challenge Programme (GCP – "http://www.generationcp.org":http://www.generationcp.org) is a globally distributed crop research consortium directed toward crop improvement through the application of comparative biology and genetic resources characterization to plant breeding. GCP adopted the development paradigm of a ‘model-driven architecture’ to achieve the interoperability and integration of diverse GCP data types that are available through distributed data sources and consumed by end-user data analysis tools. Its objective is to ensure semantic compatibility across the Consortium that will lead to the creation of robust global public goods from GCP research results. 

The GCP scientific domain model is an object model that encapsulates key crop science concepts and is documented using Unified Modeling Language (see GCP Models on "http://pantheon.generationcp.org/index.php":http://pantheon.generationcp.org/index.php). 

At the core of the GCP architecture is a scientific domain model, which is heavily parameterized with GCP-indexed ontology terms. The GCP-indexed ontology reuses established international standards where available, converts other publicly available controlled vocabularies into formally managed ontology, and develops novel ontology if no public vocabularies yet exist. General and crop-specific GCP ontologies are being developed by crop teams involving GCP and external scientific experts – in particular, for crop-specific ontology relating to plant anatomy, developmental stage, trait and phenotype for selected GCP crops. Crop ontologies are being developed for chickpea, maize, Musa, potato, rice, sorghum and wheat. The Bioversity crop descriptor lists already loaded into OBO format files provide the primary structure to develop the crop ontologies. Then, terms to be mapped to the ontologies are extracted from the crop databases where trait values have been stored by crop scientists. These sources allow the ontology teams to identify the most commonly used concept names and their interrelations. Experts validate the selection of keywords that will build the controlled vocabulary. 

These GCP ontologies will allow researchers and end users to query keywords related to traits, plant structure, growth stage, and molecular function, and link them to associated phenotyping and genotyping data sets including data on germplasm, crop physiology, geographic information, genes, QTL, etc. To reach that stage, the crop ontologies will be integrated into the data-entry user interface or data templates as picklists facilitating data annotation and submission of new terms. In addition, the GCP ontologies will be integrated with Plant Ontology (PO) and Gramene (Trait Ontology, TO; Environment Ontology, EO) to develop a common, internationally shared crop trait and anatomy ontology. The team will initiate collaboration with SONet (Scientific Observations Network) and OBOE (Extensible Observation Ontology), which proposed to integrate the GCP ontology as a study case.
The Open Biomedical Ontologies (OBO) edit tool has been used to develop the ontologies for rice, wheat and maize traits, which are currently available at "http://cropforge.org/projects/gcpontology/":http://cropforge.org/projects/gcpontology/ . The crop-specific work plans and ontologies related to other materials are published at "http://pantheon.generationcp.org":http://pantheon.generationcp.org. 
The development and curation of general-purpose ontologies will be continued and made available on the Pantheon and CropForge websites

    A core outcome set for localised prostate cancer effectiveness trials

    Objective: To develop a core outcome set (COS) applicable for effectiveness trials of all interventions for localised prostate cancer. Background: Many treatments exist for localised prostate cancer, although it is unclear which offers the optimal therapeutic ratio. This is confounded by inconsistencies in the selection, definition, measurement and reporting of outcomes in clinical trials. Subjects and methods: A list of 79 outcomes was derived from a systematic review of published localised prostate cancer effectiveness studies and semi-structured interviews with 15 prostate cancer patients. A two-stage consensus process involving 118 patients and 56 international healthcare professionals (HCPs) (cancer specialist nurses, urological surgeons and oncologists) was undertaken, consisting of a three-round Delphi survey followed by a face-to-face consensus panel meeting of 13 HCPs and 8 patients. Results: The final COS included 19 outcomes. Twelve apply to all interventions: death from prostate cancer, death from any cause, local disease recurrence, distant disease recurrence/metastases, disease progression, need for salvage therapy, overall quality of life, stress urinary incontinence, urinary function, bowel function, faecal incontinence, sexual function. Seven were intervention-specific: perioperative deaths (surgery), positive surgical margin (surgery), thromboembolic disease (surgery), bothersome or symptomatic urethral or anastomotic stricture (surgery), need for curative treatment (active surveillance), treatment failure (ablative therapy), and side effects of hormonal therapy (hormone therapy). The UK-centric participants may limit the generalisability to other countries, but trialists should reason why the COS would not be applicable. The default position should not be that a COS developed in one country will automatically not be applicable elsewhere. Conclusion: We have established a COS for trials of effectiveness in localised prostate cancer, applicable across all interventions which should be measured in all localised prostate cancer effectiveness trials

    Towards an Intelligent Tutor for Mathematical Proofs

    Get PDF
    Computer-supported learning is an increasingly important form of study since it allows for independent learning and individualized instruction. In this paper, we discuss a novel approach to developing an intelligent tutoring system for teaching textbook-style mathematical proofs. We characterize the particularities of the domain and discuss common ITS design models. Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment. We show how an intelligent tutor for textbook-style mathematical proofs can be built on top of an adapted assertion-level proof assistant by reusing representations and proof search strategies originally developed for automated and interactive theorem proving. The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.Comment: In Proceedings THedu'11, arXiv:1202.453

    The Atacama Cosmology Telescope: Cosmological parameters from three seasons of data

    Get PDF
    We present constraints on cosmological and astrophysical parameters from high-resolution microwave background maps at 148 GHz and 218 GHz made by the Atacama Cosmology Telescope (ACT) in three seasons of observations from 2008 to 2010. A model of primary cosmological and secondary foreground parameters is fit to the map power spectra and lensing deflection power spectrum, including contributions from both the thermal Sunyaev-Zeldovich (tSZ) effect and the kinematic Sunyaev-Zeldovich (kSZ) effect, Poisson and correlated anisotropy from unresolved infrared sources, radio sources, and the correlation between the tSZ effect and infrared sources. The power ell^2 C_ell/2pi of the thermal SZ power spectrum at 148 GHz is measured to be 3.4 +\- 1.4 muK^2 at ell=3000, while the corresponding amplitude of the kinematic SZ power spectrum has a 95% confidence level upper limit of 8.6 muK^2. Combining ACT power spectra with the WMAP 7-year temperature and polarization power spectra, we find excellent consistency with the LCDM model. We constrain the number of effective relativistic degrees of freedom in the early universe to be Neff=2.79 +\- 0.56, in agreement with the canonical value of Neff=3.046 for three massless neutrinos. We constrain the sum of the neutrino masses to be Sigma m_nu < 0.39 eV at 95% confidence when combining ACT and WMAP 7-year data with BAO and Hubble constant measurements. We constrain the amount of primordial helium to be Yp = 0.225 +\- 0.034, and measure no variation in the fine structure constant alpha since recombination, with alpha/alpha0 = 1.004 +/- 0.005. We also find no evidence for any running of the scalar spectral index, dns/dlnk = -0.004 +\- 0.012.Comment: 26 pages, 22 figures. This paper is a companion to Das et al. (2013) and Dunkley et al.
