05-05 "Teaching Ecological and Feminist Economics in the Principles Course"

It can be difficult to incorporate ecological and feminist concerns into introductory courses based on neoclassical analysis. We have faced these issues head-on as we have worked on writing introductory economics textbooks, Microeconomics in Context (Goodwin, Nelson, Ackerman and Weisskopf, 2005) and Macroeconomics in Context (in progress). In this essay, we will describe how we have modified the introductory curriculum to encompass these perspectives.

Teaching Ecological and Feminist Economics in the Principles Course

It can be difficult to incorporate ecological and feminist concerns into introductory courses, when one is also obliged to teach neoclassical analysis. In this essay we briefly describe how one might extend existing “multi-paradigmatic” approaches to feminist and ecological concerns, and then present an new alternative approach that may be more suitable for some students. This “broader questions and bigger toolbox” approach can be applied in both microeconomics and macroeconomics introductory classrooms

Physiotherapy after arthroscopic partial meniscectomy surgery: An assessment of costs to the National Health Service, patients and society

Objectives: The purpose of this study was to determine and inform clinicians, managers, and budget allocators of the costs incurred to the British National Health Service (NHS), patient, and society when attending clinic-based physiotherapy compared with not attending clinic-based physiotherapy after arthroscopic partial meniscectomy surgery. Methods: The valuation principle used in this study was the economic concept of opportunity cost. Costs were referred to as direct medical (NHS), direct nonmedical (patient), and indirect (societal) costs. Due to the difficulties of their measurement and valuation, intangible costs, in the form of pain and anxiety related to the effect of receiving or not receiving treatment, have not been considered in this analysis. Results: Providing clinic-based physiotherapy after knee arthroscopic partial meniscectomy surgery is more costly to the NHS and patient, but no more costly to society than when not providing it and does not result in reduced contact with the NHS. Conclusions: Clinic-based physiotherapy after knee arthroscopic partial meniscectomy surgery is costly and evidence is needed that its effectiveness is high enough to support its use

Implementation and sustainability factors of two early-stage breast cancer conversation aids in diverse practices

BACKGROUND: Conversation aids can facilitate shared decision-making and improve patient-centered outcomes. However, few examples exist of sustained use of conversation aids in routine care due to numerous barriers at clinical and organizational levels. We explored factors that will promote the sustained use of two early-stage breast cancer conversation aids. We examined differences in opinions between the two conversation aids and across socioeconomic strata. METHODS: We nested this study within a randomized controlled trial that demonstrated the effectiveness of two early-stage breast cancer surgery conversation aids, one text-based and one picture-based. These conversation aids facilitated more shared decision-making and improved the decision process, among other outcomes, across four health systems with socioeconomically diverse patient populations. We conducted semi-structured interviews with a purposive sample of patient participants across conversation aid assignment and socioeconomic status (SES) and collected observations and field notes. We interviewed trial surgeons and other stakeholders. Two independent coders conducted framework analysis using the NOrmalization MeAsure Development through Normalization Process Theory. We also conducted an inductive analysis. We conducted additional sub-analyses based on conversation aid assignment and patient SES. RESULTS: We conducted 73 semi-structured interviews with 43 patients, 16 surgeons, and 14 stakeholders like nurses, cancer center directors, and electronic health record (EHR) experts. Patients and surgeons felt the conversation aids should be used in breast cancer care in the future and were open to various methods of giving and receiving the conversation aid (EHR, email, patient portal, before consultation). Patients of higher SES were more likely to note the conversation aids influenced their treatment discussion, while patients of lower SES noted more influence on their decision-making. Intervention surgeons reported using the conversation aids did not lengthen their typical consultation time. Most intervention surgeons felt using the conversation aids enhanced their usual care after using it a few times, and most patients felt it appeared part of their normal routine. CONCLUSIONS: Key factors that will guide the future sustained implementation of the conversation aids include adapting to existing clinical workflows, flexibility of use, patient characteristics, and communication preferences.

Mineralogical controls on porosity and water chemistry during O2-SO2-CO2 reaction of CO2 storage reservoir and cap-rock core

Reservoir and cap-rock core samples with variable lithology's representative of siliciclastic reservoirs used for CO storage have been characterized and reacted at reservoir conditions with an impure CO stream and low salinity brine. Cores from a target CO storage site in Queensland, Australia were tested. Mineralogical controls on the resulting changes to porosity and water chemistry have been identified. The tested siliciclastic reservoir core samples can be grouped generally into three responses to impure CO-brine reaction, dependent on mineralogy. The mineralogically clean quartzose reservoir cores had high porosities, with negligible change after reaction, in resolvable porosity or mineralogy, calculated using X-ray micro computed tomography and QEMSCAN. However, strong brine acidification and a high concentration of dissolved sulphate were generated in experiments owing to minimal mineral buffering. Also, the movement of kaolin has the potential to block pore throats and reduce permeability. The reaction of the impure CO-brine with calcite-cemented cap-rock core samples caused the largest porosity changes after reaction through calcite dissolution; to the extent that one sample developed a connection of open pores that extended into the core sub-plug. This has the potential to both favor injectivity but also affect CO migration. The dissolution of calcite caused the buffering of acidity resulting in no significant observable silicate dissolution. Clay-rich cap-rock core samples with minor amounts of carbonate minerals had only small changes after reaction. Created porosity appeared mainly disconnected. Changes were instead associated with decreases in density from Fe-leaching of chlorite or dissolution of minor amounts of carbonates and plagioclase. The interbedded sandstone and shale core also developed increased porosity parallel to bedding through dissolution of carbonates and reactive silicates in the sandy layers. Tight interbedded cap-rocks could be expected to act as baffles to fluids preventing vertical fluid migration. Concentrations of dissolved elements including Ca, Fe, Mn, and Ni increased during reactions of several core samples, with Mn, Mg, Co, and Zn correlated with Ca from cap-rock cores. Precipitation of gypsum, Fe-oxides and clays on seal core samples sequestered dissolved elements including Fe through co-precipitation or adsorption. A conceptual model of impure CO-water-rock interactions for a siliciclastic reservoir is discussed

Environmental Cues and Fungi Morphology

Candida albicans, a symbiotic yeast in the human gut, and Neurospora crassa, a filamentous bread mold, are distinct in habitat, morphology, and behavior. However, both fungi are equally susceptible to the ongoing flow of stimuli present within the environment. The objective of our research is to understand how different fungi respond to specific cues found within or outside their natural environment. Four stimuli were tested on C. albicans: estradiol (E2), media morphology, and irradiated and non-radiated plastic microfibers. Three stimuli were tested on N. crassa: plastic non-radiated microfibers, simulated microgravity, and cold shock. C. albicans was tested only on solid agar plates, while N. crassa was tested on both liquid and solid agar media. Specialized minimal media plates containing microfibers were made to test irradiated and non-radiated microfiber exposure. While C. albicans expressed no sensitivity to 0.1nM E2, it displayed three types of morphology when grown on either minimal, Spider, or YEPD media. N. crassa showed no sensitivity towards microfibers, but C. albicans exhibited varying degrees of inhibition for colony formation. Under simulated microgravity, N. crassa did not show significant morphological differences besides a possible increase in the amount of conidia present, however, results are inconclusive

Informing evidence-based policies for ageing and health in Ghana

Problem: Ghana's population is ageing. In 2011, the Government of Ghana requested technical support from the World Health Organization (WHO) to help revise national policies on ageing and health. Approach: We applied WHO's knowledge translation framework on ageing and health to assist evidence based policy-making in Ghana. First, we defined priority problems and health system responses by performing a country assessment of epidemiologic data, policy review, site visits and interviews of key informants. Second, we gathered evidence on effective health systems interventions in low- middle- and high-income countries. Third, key stakeholders were engaged in a policy dialogue. Fourth, policy briefs were developed and presented to the Ghana Health Services. Local setting: Ghana has a well-structured health system that can adapt to meet the health care needs of older people. Relevant changes: Six problems were selected as priorities, however after the policy dialogue, only five were agreed as priorities by the stakeholders. The key stakeholders drafted evidence-based policy recommendations that were used to develop policy briefs. The briefs were presented to the Ghana Health Service in 2014. Lessons learnt: The framework can be used to build local capacity on evidence-informed policy-making. However, knowledge translation tools need further development to be used in low-income countries and in the field of ageing. The terms and language of the tools need to be adapted to local contexts. Evidence for health system interventions on ageing populations is very limited, particularly for low- and middle-income settings
