Diagnosis--A Part of Content Area Reading

One of the major trends in education is that of relating reading instruction to the content areas. Middle and secondary school content specialists have been asked to incorporate appropriate reading or learning skills into their content teaching. Many content specialists have recognized this need and are attempting to meet the challenge. Much in-service education is being provided to assist these teachers. Additionally, many state certification standards are requiring that pre-service programs provide new content specialists with necessary instruction in teaching reading in their content areas

Trans∗Vulnerability And Digital Research Ethics: A Qubit Ethical Analysis Of Transparency Activism

Trans communities across the United States are under assault. Researchers seeking to work with trans people and other multiply marginalized and underrepresented communities must attend to ethical research practices within the communities in which they participate. Digital research ethics is particularly murky with issues of embodiment, vulnerability, and unclear IRB guidance. Comparing two transparency activist organizations-Wikileaks and DDoSecrets-we introduce qubit ethics, a trans material, trans-corporeal ethics of care as praxis within vulnerable online communities. We then demonstrate how this unique approach to research design allows for the complex entanglements that is trans life, particularly digital life. Finally, we present clear take-Aways for qubit-ethics informed social justice research

Making a case for telehealth: measuring the carbon cost of health-related travel

Background: Telehealth services are promoted to reduce the cost of travel for people living in rural areas. The previous Australian Government, through the national Digital Economy Strategy, invested heavily in telehealth service development, at the same time introducing a carbon pricing mechanism. In planning a range of new telehealth services to a rural community the authors sought to quantify the travel conducted by people from one rural area in Australia to access health care, and to calculate the associated carbon emissions.Methods: A population survey was conducted over a 1-week period of health-related travel events for the year 1 July 2011 to 30 June 2012 of all households on King Island, a community situated between the Australian mainland state of Victoria and the state of Tasmania. Validated emissions calculators were sourced from the Carbon Neutral website, including the vehicle and fuel use calculator and air travel carbon calculator, to calculate the total emissions associated with the fuel burned in tonnes of carbon dioxide equivalent (tCO2e).Results: Thirty nine percent of the population (625 participants) reported a total of 511 healthcare-related travel events. Participants travelled a total of 346 573 km and generated 0.22 tCO2e per capita. Participants paid the cost of their own travel more than 70% of the time.Conclusions: Dependence on fossil fuels for transport in a carbon economy has a significant impact on total healthcare carbon emissions. Alternative models of care, such as telehealth, need be developed for an environmentally sustainable healthcare system for rural and remote areas

Towards detecting super-GeV dark matter via annihilation to neutrinos

The next generation of neutrino telescopes will feature unprecedented sensitivities in the detection of neutrinos. Here we study the capabilities of a large-scale neutrino telescope, like the fully-operating KM3NeT experiment in the near future, for detecting dark matter annihilation signals from the Galactic Centre. We consider both ORCA and ARCA detectors, covering dark matter masses from a few GeV to 100 TeV. We obtain the sensitivities with a maximum-likelihood analysis method and present them as upper limits in the thermally averaged annihilation cross-section into Standard Model fermions. Our projections show that the sensitivity of such a neutrino telescope can reach the thermal relic line for $m_{\chi}\gtrsim 1\,{\rm TeV}$ and for $m_\chi \simeq$ few GeV, for the NFW dark matter density profile. This demonstrates that ORCA- and ARCA-like detectors will be able to perform competitive dark matter searches in a wide range of masses. The implications of these striking projections are investigated in a few selected dark matter particle models, where we show that neutrino telescopes are able to probe new parameter space

Robust Limits from Upcoming Neutrino Telescopes and Implications on Minimal Dark Matter Models

Experimental developments in neutrino telescopes are drastically improving their ability to constrain the annihilation cross-section of dark matter. In this paper, we employ an angular power spectrum analysis method to probe the galactic and extra-galactic dark matter signals with neutrino telescopes. We first derive projections for a next generation of neutrino telescope that is inspired by KM3NeT. We emphasise that such analysis is much less sensitive to the choice of dark matter density profile. Remarkably, the projected sensitivity is improved by more than an order of magnitude with respect to the existing limits obtained by assuming the Burkert dark matter density profile describing the galactic halo. Second, we analyse minimal extensions to the Standard Model that will be maximally probed by the next generation of neutrino telescopes. As benchmark scenarios, we consider Dirac dark matter in $s$- and $t$-channel models with vector and scalar mediators. We follow a global approach by examining all relevant complementary experimental constraints. We find that neutrino telescopes will be able to competitively probe significant portions of parameter space. Interestingly, the anomaly-free $L_{\mu}-L_{\tau}$ model can potentially be explored in regions where the relic abundance is achieved through freeze-out mechanism

Effects of Long-Term Hypoxia on Enzymes of Carbohydrate Metabolism in the Gulf killifish, Fundulus grandis

The goal of the current study was to generate a comprehensive, multi-tissue perspective of the effects of chronic hypoxic exposure on carbohydrate metabolism in the Gulf killifish Fundulus grandis. Fish were held at approximately 1.3·mg·l–1 dissolved oxygen (~3.6·kPa) for 4·weeks, after which maximal activities were measured for all glycolytic enzymes in four tissues (white skeletal muscle, liver, heart and brain), as well as for enzymes of glycogen metabolism (in muscle and liver) and gluconeogenesis (in liver). The specific activities of enzymes of glycolysis and glycogen metabolism were strongly suppressed by hypoxia in white skeletal muscle, which may reflect decreased energy demand in this tissue during chronic hypoxia. In contrast, several enzyme specific activities were higher in liver tissue after hypoxic exposure, suggesting increased capacity for carbohydrate metabolism. Hypoxic exposure affected fewer enzymes in heart and brain than in skeletal muscle and liver, and the changes were smaller in magnitude, perhaps due to preferential perfusion of heart and brain during hypoxia. The specific activities of some gluconeogenic enzymes increased in liver during long-term hypoxic exposure, which may be coupled to increased protein catabolism in skeletal muscle. These results demonstrate that when intact fish are subjected to prolonged hypoxia, enzyme activities respond in a tissue-specific fashion reflecting the balance of energetic demands, metabolic role and oxygen supply of particular tissues. Furthermore, within glycolysis, the effects of hypoxia varied among enzymes, rather than being uniformly distributed among pathway enzymes

How people with chronic illnesses view their care in general practice: a qualitative study

The document attached has been archived with permission from the editor of the Medical Journal of Australia. An external link to the publisher’s copy is included.Objectives: To explore the perceptions of patients with chronic conditions about the nature and quality of their care in general practice. Design: Qualitative study using focus group methods conducted 1 June to 30 November 2002. Participants and setting: 76 consumers in 12 focus groups in New South Wales and South Australia. Main outcome measures: Recurring issues and themes on care received in general practice. Results: Three groups of priorities emerged. One centred on the quality of doctors, including technical competence, interpersonal skills, time for the patient in the consultation and continuity of care. A second concerned the role of patients and consumer organisations, with patients wanting (i) recognition of their knowledge about their condition and self-management, and (ii) for GPs to develop closer links with consumer organisations and inform patients about them. The third focused on the practice team and the importance of practice nurses and receptionists. Conclusion: GPs should consider the amount of time they spend with chronically ill patients, and their interpersonal skills and understanding of patients’ needs. They need to be better informed about the benefits of patient self-management and consumer organisations, and to incorporate them into their care. They also need to review how their practice nurses and receptionists can maximise the care of patients.Fernando A Infante, Judith G Proudfoot, Gawaine Powell Davies, Tanya K Bubner, Chris H Holton, Justin J Beilby and Mark F Harri

Emerging infectious diseases among indigenous peoples

Many indigenous peoples are at higher risk for emerging infectious diseases compared to other populations. This conference panel focused on diseases of particular concern to Native Americans (American Indians and Alaska Natives), Australian aboriginal peoples, and the Maori of New Zealand. Important emerging diseases among these groups include respiratory tract infections, infections with antimicrobial-resistant organisms, zoonotic diseases, viral hepatitis, Helicobacter pylori and respiratory syncytial virus infections, diseases caused by Group A and B streptococcus, tuberculosis, and bacteremia and meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis. Although the populations discussed are diverse, they have many things in common, including a high risk for many emerging infectious diseases, the requirement for culturally appropriate prevention and control strategies, and the need for increased leadership within communities of indigenous peoples
