Marine Debris Effect on Marine Life and Their Habitat

Marine debris originates from a large range of causes. Materials that are illegally disposed of and that are incorrectly transferred or deposited may become aquatic waste. Plastics, glass, metal, paper, fabric, rubber and wood are the most widespread marine debris. Plastic is what comes to mind when one speaks about sea pollution. Plastic bags are able to enclose and suffocate marine mammals, whales, seabirds and sea turtles. Marine debris is a rising global concern that is wreaking havoc on the atmosphere and the economy. It obstructs navigation, entangles birds, pollutes beaches, and much more. Of the two beaches surveyed Orchard Beach in Bronx Ny and Long Beach in Stratford CT, the most common found marine debris was cigarette butts, food wrappers and plastic bottle/caps

The yummy and the yucky: Expressive language and the agreeable

I probe the judgments of the agreeable that we make about food and drink. I first separate different concerns that we might have with food and drink. After that, I address expressive language by first sketching an evolutionary language-game-theoretic approach for referential language. I then try to extend it to expressive language, showing how expressive signaling might be likely to evolve. Given an account of expressive prediction, and its point, I turn to the Frege-Geach problem for the agreeable. I show how a proper understanding of what expression is, in the evolutionary language-game-theoretic framework, allows us to side-step a central aspect the problem

Stakeholder collaboration and heritage management

This article examines a collaborative approach to the relationship between heritage management and tourism development in Luang Prabang, Laos. The purpose is to examine stakeholder collaboration and management roles, heritage tourism development, as well as the interdependence of the heritage conservation and tourism relationship. The research examines a UNESCO/Norwegian government project, which aiming to promote collaboration between heritage conservation and tourism through stakeholder involvement. Five aspects are explored: channels of communication between the heritage and the tourism groups, generating income for heritage conservation and management, involving the local community in decisionmaking, involving the local community in tourism activities, and an assessment of the extent and success of stakeholder collaboration

Socially-augmented argumentation tools: rationale, design and evaluation of a debate dashboard

Collaborative Computer-Supported Argument Visualization (CCSAV) is a technical methodology that offers support for online collective deliberation over complex dilemmas. As compared with more traditional conversational technologies, like wikis and forums, CCSAV is designed to promote more critical thinking and evidence-based reasoning, by using representations that highlight conceptual relationships between contributions, and through computational analytics that assess the structural integrity of the network. However, to date, CCSAV tools have achieved adoption primarily in small-scale educational contexts, and only to a limited degree in real world applications. We hypothesise that by reifying conversations as logical maps to address the shortcomings of chronological streams, CCSAV tools underestimate the importance of participation and interaction in enhancing collaborative knowledge-building. We argue, therefore, that CCSAV platforms should be socially augmented in order to improve their mediation capability. Drawing on Clark and Brennan’s influential Common Ground theory, we designed a Debate Dashboard, which augmented a CCSAV tool with a set of widgets that deliver meta-information about participants and the interaction process. An empirical study simulating a moderately sized collective deliberation scenario provides evidence that this experimental version outperformed the control version on a range of indicators, including usability, mutual understanding, quality of perceived collaboration, and accuracy of individual decisions. No evidence was found that the addition of the Debate Dashboard impeded the quality of the argumentation or the richness of content

Enhancing Interdisciplinary Instruction in General and Special Education: Thematic Units and Technology

This article discusses interdisciplinary thematic units in the context of special and general education curricula and focuses on ways technology can be used to enhance interdisciplinary thematic units. Examples of curriculum integration activities enhanced by technology are provided in the context of productivity tools, presentation and multimedia tools, contextual themed software, and Web-based activities.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

FLASH Irradiation Results in Reduced Severe Skin Toxicity Compared to Conventional-Dose-Rate Irradiation

Radiation therapy, along with surgery and chemotherapy, is one of the main treatments for cancer. While radiotherapy is highly effective in the treatment of localized tumors, its main limitation is its toxicity to normal tissue. Previous preclinical studies have reported that ultra-high dose-rate (FLASH) irradiation results in reduced toxicity to normal tissues while controlling tumor growth to a similar extent relative to conventional-dose-rate (CONV) irradiation. To our knowledge this is the first report of a dose-response study in mice comparing the effect of FLASH irradiation vs. CONV irradiation on skin toxicity. We found that FLASH irradiation results in both a lower incidence and lower severity of skin ulceration than CONV irradiation 8 weeks after single-fraction hemithoracic irradiation at high doses (30 and 40 Gy). Survival was also higher after FLASH hemithoracic irradiation (median survival >180 days at doses of 30 and 40 Gy) compared to CONV irradiation (median survival 100 and 52 days at 30 and 40 Gy, respectively). No ulceration was observed at doses 20 Gy or below in either FLASH or CONV. These results suggest a shifting of the dose-response curve for radiation-induced skin ulceration to the right for FLASH, compared to CONV irradiation, suggesting the potential for an enhanced therapeutic index for radiation therapy of cancer
