The Quest of Inclusion: Understandings of Ableism, Pedagogy and the Right To Belong
The intent of this work is to explore how children, youth, and adults with disabilities are discriminated against in cultural systems, specifically the education system, and how the beliefs and structures encompassed in these systems create and recreate the phenomena of ableism. This study will explore the hegemony of ableism within school cultures by exposing prevailing discourses and the systems that enforce these discriminatory discourses and educational practices. Additionally, it will illustrate significant human rights infractions and discriminatory processes that keep disabled peoples throughout the world in states of marginalization and oppression.
The analysis of this study shows resistance to the oppression of people with disabilities through the use of critical disability theory, legal theory, and social justice philosophy. In addition, the advancement of inclusive education as a human right is offered as a solution to the collective oppression and states of disenfranchisement that many disabled people’s experience.
The exploration of moral and legal theory, equality jurisprudence, and libratory pedagogy will advance a collective human rights framework as an educational model for school cultures globally. This analysis will utilize an equality premise known as the “right to belong” to defend inclusive education as a fundamental human right. In support of this fundamental right, a theoretical base for inclusive pedagogies reveals how the deconstruction of hegemonic practices and, simultaneously, the development of transformative educational models of learning are necessary “best practices” in the pursuit of equality for all disabled students. This work concludes with recommendations for changes in educational leadership, philosophy, and research of education for disabled students

Condensation from a large HCDA vapor-gas bubble onto structures. [LMFBR]
A mechanistic assessment of the consequences of a Hypothetical Core Disruptive Accident (HCDA) for a sodium-cooled breeder reactor will require analyses that determine the quantity of fuel released from the primary containment. This release is due to fuel melting, vaporization, and movement through the sodium pool and leakage through the assumed damaged vessel head closure. According to some views, this fuel may move through the cooler sodium pool as a large fuel vapor bubble containing non-condensable fission gases. There is potential for removal of the radionuclide source during this transport by condensation onto structural material (i.e., instrument carriers, control rod drives, support structures, etc.) as well as at the bubble interface. Previous analyses have estimated the condensation rates at the bubble interface. The work described extends a previous model to condensation on structural surfaces in the bubble path. The results of the analysis show that the condensation model for thick steel structures yields similar results as the previous model for condensation on the bubble interface. Due to the high thermal conductivities of both sodium and steel, the mass transfer on the vapor side becomes the controlling factor for condensation. In the case of thin steel structures, the interface temperature rise becomes significant (melting temperatures may be reached) due to the limited heat sink provided by the structure
c-Myc co-ordinates mRNA cap methylation and ribosomal RNA production
The mRNA cap is a structure added to RNA pol II transcripts in eukaryotes, which recruits factors involved in RNA processing, nuclear export and translation initiation. RNA guanine-7 methyltransferase (RNMT)–RNA-activating miniprotein (RAM), the mRNA cap methyltransferase complex, completes the basic functional mRNA cap structure, cap 0, by methylating the cap guanosine. Here, we report that RNMT–RAM co-ordinates mRNA processing with ribosome production. Suppression of RNMT–RAM reduces synthesis of the 45S ribosomal RNA (rRNA) precursor. RNMT–RAM is required for c-Myc expression, a major regulator of RNA pol I, which synthesises 45S rRNA. Constitutive expression of c-Myc restores rRNA synthesis when RNMT–RAM is suppressed, indicating that RNMT–RAM controls rRNA production predominantly by controlling c-Myc expression. We report that RNMT–RAM is recruited to the ribosomal DNA locus, which may contribute to rRNA synthesis in certain contexts
Development of a DNA Barcoding System for Seagrasses: Successful but Not Simple
Seagrasses, a unique group of submerged flowering plants, profoundly influence the physical, chemical and biological environments of coastal waters through their high primary productivity and nutrient recycling ability. They provide habitat for aquatic life, alter water flow, stabilize the ground and mitigate the impact of nutrient pollution. at the coast region. Although on a global scale seagrasses represent less than 0.1% of the angiosperm taxa, the taxonomical ambiguity in delineating seagrass species is high. Thus, the taxonomy of several genera is unsolved. While seagrasses are capable of performing both, sexual and asexual reproduction, vegetative reproduction is common and sexual progenies are always short lived and epimeral in nature. This makes species differentiation often difficult, especially for non-taxonomists since the flower as a distinct morphological trait is missing. Our goal is to develop a DNA barcoding system assisting also non-taxonomists to identify regional seagrass species. The results will be corroborated by publicly available sequence data. The main focus is on the 14 described seagrass species of India, supplemented with seagrasses from temperate regions. According to the recommendations of the Consortium for the Barcoding of Life (CBOL) rbcL and matK were used in this study. After optimization of the DNA extraction method from preserved seagrass material, the respective sequences were amplified from all species analyzed. Tree- and character-based approaches demonstrate that the rbcL sequence fragment is capable of resolving up to family and genus level. Only matK sequences were reliable in resolving species and partially the ecotype level. Additionally, a plastidic gene spacer was included in the analysis to confirm the identification level. Although the analysis of these three loci solved several nodes, a few complexes remained unsolved, even when constructing a combined tree for all three loci. Our approaches contribute to the understanding of the morphological plasticity of seagrasses versus genetic differentiation
Living with chronic pain: Patients' experiences with healthcare services in Norway
Aim
To explore the experiences with healthcare received by people living with chronic nonmalignant pain in Norway.
Design
A descriptive and explorative qualitative design.
Methods
A total of 18 individual semistructured interviews was conducted in 2015. Qualitative content analysis was applied.
Results
The findings revealed challenges related to a multifaceted pain condition. Participants described interactions with a supportive health care where being listened to, believed in and experiencing mutual trust were emphasized. When interactions with healthcare professionals made the participants feel insignificant, they found it difficult to express their needs, which seemed to reinforce practical difficulties and unfulfilled expectations and make them lose hope in their recovery. This implies the importance of a holistic understanding of and support for more person‐centred practice to accommodate patients' expectations and expressed needs. Here, the nurses have an essential role in having a positive impact on future healthcare services.publishedVersio
Media language: Video practices
This project explores the blog as a context considering the articulations between the context and content (blog and videos) forming this project. In order to do so, hyperlinks to practitioners’ videos (uploaded to individual Vimeo accounts), are gathered together on a blog page. Contributors are asked to consider the prompt of a glass of water for a video-based active reflection on their practice. A glass of water is an object of the everyday, yet one often present in interviews; this project started as a series of interviews. The water or the glass can be present or not present in the video, for example materiality could be considered, or perhaps the ‘publicness’ connected with the water glass at a site of presentation could be explored. Other ways may be found. This is a collaborative work where practitioners survey their individual use of media through the prescribed method of digital video. The result of the work can be accessed on Seminar Project website ( http://www.kmbosy.com/blog/seminar-project)
Readers building fictional worlds:visual representations, poetry, and cognition
This article explores the complex nature of the literature classroom by drawing on the cognitive linguistic framework Text World Theory to examine the teacher’s role as facilitator and mediator of reading. Specifically, the article looks at how one teacher used visual representations as a way of allowing students to engage in a more personal and less teacher-driven transaction with a poem, and to encourage them to reflect on their own roles as active makers of meaning and knowledge in the classroom. The article shows how teachers can be mindful of the various contextual factors that can privilege and legitimise certain kinds of response in the classroom and be wary of external factors and pressures that can promote the idea of preconceived knowledge. The teacher in the case study presented was able to both facilitate the experience of reading poetry in an unmediated way and also develop her students’ metacognition in relation to the reading process itself. The article shows how Text World Theory’s status as a socio-cognitive grammar may be of benefit to teachers in understanding the nature of communicative interaction and literary transaction
Comparing COI and ITS as DNA Barcode Markers for Mushrooms and Allies (Agaricomycotina)
DNA barcoding is an approach to rapidly identify species using short, standard genetic markers. The mitochondrial cytochrome oxidase I gene (COI) has been proposed as the universal barcode locus, but its utility for barcoding in mushrooms (ca. 20,000 species) has not been established. We succeeded in generating 167 partial COI sequences (∼450 bp) representing ∼100 morphospecies from ∼650 collections of Agaricomycotina using several sets of new primers. Large introns (∼1500 bp) at variable locations were detected in ∼5% of the sequences we obtained. We suspect that widespread presence of large introns is responsible for our low PCR success (∼30%) with this locus. We also sequenced the nuclear internal transcribed spacer rDNA regions (ITS) to compare with COI. Among the small proportion of taxa for which COI could be sequenced, COI and ITS perform similarly as a barcode. However, in a densely sampled set of closely related taxa, COI was less divergent than ITS and failed to distinguish all terminal clades. Given our results and the wealth of ITS data already available in public databases, we recommend that COI be abandoned in favor of ITS as the primary DNA barcode locus in mushrooms
Leisure, refuge and solidarity:messages in visitors’ books as microforms of travel writing
Visitors’ books not only trace developments in modern tourism, but they also reveal changes in the socio-cultural and language attitudes of travellers from all walks of life over prolonged periods of time. This article investigates messages in visitors’ books from Wales from the mid-nineteenth century up to the present and argues for their recognition as microforms of travel writing. Despite their brevity, entries in visitors’ books are a highly complex form of travel writing particularly in the inscribers’ self-fashioning of identity for future readers. The article examines how writerly choices are not only directly rooted in the discourse of travel, but also in socio-political circumstances in the individual travellers’ countries of origin and their travel destinations
