Get PDFIn this conceptual framework paper, I critically chronicle the historiography, policy, and scientific literatures of learning disabilities (ld) and provide a conceptual framework for reframing these as master narratives. I defined master narratives as the pre-existent sociocultural forms of interpretation. I interrogated the a) cultural-historical; b) the federal definition of ld within idea, c) the educational-professional academic and focused on, the d) social and emotional literature of ld. The master narratives from these literatures included: a) ld as a boy who struggles with reading, ld as a symbolic complex, and the legacy of the term feebleminded , d) assumptions about learning, ab/normality, difference, communication, dis/ability, culture and diversity, and issues of representation of student voice, e) a medical-psychological deficit oriented neurological, cognitive and instructional master narratives that assume dis/Ability within their neurology. These framings ignore the intersectional discursive, emotive and cultural-historical material contexts of students\u27 lived experiences
Origin of Large Effective Phonon Magnetic Moments in Monolayer MoS2
Get PDFRecent helicity-resolved magneto-Raman spectroscopy measurement demonstrates large effective phonon magnetic moments of ∼2.5 μB in monolayer MoS2, highlighting resonant excitation of bright excitons as a feasible route to activate Γ-point circularly polarized phonons in transition metal dichalcogenides. However, a microscopic picture of this intriguing phenomenon remains lacking. In this work, we show that an orbital transition between the split conduction bands (Δ0 = 4 meV) of MoS2 couples to the doubly degenerate E″ phonon mode (Ω0 = 33 meV), forming two hybridized states. Our phononic and electronic Raman scattering measurements capture these two states: (i) one with predominantly phonon contribution in the helicity-switched channels and (ii) one with primarily orbital contribution in the helicity-conserved channels. An orbital-phonon coupling model successfully reproduces the large effective magnetic moments of the circularly polarized phonons and explains their thermodynamic properties. Strikingly, the Raman mode from the orbital transition is superimposed on a strong quasi-elastic scattering background, indicating the presence of spin fluctuations. As a result, the electrons excited to the conduction bands through the exciton exhibit paramagnetic behavior although MoS2 is generally considered as a nonmagnetic material. By depositing nanometer-thickness nickel thin films on monolayer MoS2, we tune the electronic structure so that the A exciton perfectly overlaps with the 633 nm laser. The optimization of resonance excitation leads to pronounced tunability of the orbital-phonon hybridized states. Our results generalize the orbital-phonon coupling model of effective phonon magnetic moments to material systems beyond the paramagnets and magnets
Variations to the Traditional Delivery of EMDR
No full textEye Movement Desensitization and Reprocessing (EMDR) is an often criticized but effective therapy in the treatment of PTSD. The use of bilateral stimulation, often in the form of alternating eye movements, is scrutinized and opponents argue that it is not necessary for EMDR to be effective. This paper’s author analyzed the current research on EMDR and its multiple delivery variations, including variations in bilateral stimulation methods and combinations of EMDR with other therapies, such as cognitive behavioral therapy (CBT). Multiple studies exist that test eye movements as an effective method of bilateral stimulation, while other methods, such as the “butterfly technique” and hand tapping, do show some positive results. Results show that EMDR is effective, with eye movements being the most effective bilateral stimulation method. EMDR can also be effective when combined with other therapies and when administered over a virtual setting. Finally, eye movements are a necessary component of EMDR therapy and should continue to be included as part of the eight step EMDR therapy program. Future research on the topic should focus on EMDR administration in clinical settings and include replication of studies that test EMDR with and without eye movements
Prison Environment and Conditions Affect Recidivism Rates — Norway and South Africa
Get PDFHarsh prison conditions and lack of rehabilitation and reintegration programs in South African prisons reflect the high recidivism rates in the country. South African prisoners are subject to inhumane conditions such as overcrowding and health concerns, violations of human rights, and are stripped of their dignity. Paired with social stigma against those who have been incarcerated, these inhumane conditions lead to poor reintegration and higher recidivism rates. This research project advocates for prison reform focusing on rehabilitation, reintegration, and improved facility conditions. There are multiple examples of competent and humane prisons in the world, such as Norway’s correctional institutions, which have been long standing advocates for prison reform. Norwegian prisons implement services that include rehabilitation, vocational, educational, and therapeutic programs. These services have proven to lower recidivism rates and improve overall quality of life in prisons including a smooth transition back into society. Since the development of this revised prison system in Norway in the 1990’s, recidivism rates have dropped from 70% to 20% in 2023. When comparing this to South Africa’s recidivism rate of 86%-94% there is no evidence to suggest that harsher punishment and confinement conditions reduce recidivism. Unlike South African prisons, Norwegian facilities have an emphasis on creating and maintaining a humane environment that mimics daily life and improves mental health outcomes
Countering Deficit Ideologies in Adult Multilingual Education
No full textWhen I first started my English language teaching career in Egypt, I relied heavily on established English language textbooks and trusted their content. One day, I was teaching an Egyptian 8-year-old who had brown curly hair and a light brown skin complexion. The materials used the picture of a young blond white woman wearing pearls to describe the word “beautiful” and used a picture of a younger child who had brown curly hair and a light brown skin complexion with obvious signs of physical abuse to refer to the word “ugly”. At that time, I did not know much about theories related to multilingualism and multilingual education. However, my background education in postcolonial studies guided me to understand that this lesson was a reflection of the remaining traces of colonialism and the othering of non-white individuals (Gorski, 2011). Right after this lesson, I wrote a post on social media criticizing the lesson, and I tagged a very well-known publishing company. They got back to me, letting me know that they had updated the lesson and that a lot of their materials are “many years old” (Facebook user, 2022) and needed review. This incident made me think about all the other biased, many-year-old teaching materials that have been normalized. In addition, it made me reflect on my experience growing up as an English language learner and all the teaching curricula that promoted Eurocentrism and marginalized the diverse nature of the English language learner across the globe (Flores & Rosa, 2023; Khodadady & Shayesteh, 2016). I remember teachers inferiorizing my and other learners\u27 Egyptian Arabic accents when attempting to speak English, promoting nativeness, and marginalizing linguistic diversity (Flores & Rosa, 2023). Paulo Freire (1973) defines this process of one’s ability to identify and challenge issues of inequalities and racism as critical consciousness

No full textIn March of 2025, the environmental group Greenpeace was found liable for nearly $667 million to Energy Transfer, the oil company behind the Dakota Access Pipeline (DAPL). The lawsuit centered around Greenpeace\u27s involvement in DAPL protests nearly a decade earlier. Energy Transfer\u27s lawsuit is a textbook Strategic Lawsuit Against Public Participation (SLAPP), a lawsuit that weaponizes civic torts to infringe upon First Amendment rights. The jury delivered a verdict that is unprecedented in SLAPP litigation--one that has the potential to chill future public participation. This thesis uses a crisis narrative framework to analyze Greenpeace\u27s public response to the lawsuit, particularly the language Greenpeace uses to renew support for their organization and the broader environmental movement
