description: SS433, located at the center of the supernova remnant W50, is a close proximity binary system consisting of a compact star and a normal star. Jets of material are directed outwards from the vicinity of the compact star symmetrically to the east and west. Non-thermal hard X-ray emission is detected from lobes lying on both sides. Shock accelerated electrons are expected to generate sub-TeV gamma rays through the inverse-Compton process in the lobes. Observations of the western X-ray lobe region of SS433/W50 system have been performed to detect sub-TeV gamma-rays using the 10m CANGAROO-II telescope in August and September, 2001, and July and September, 2002. The total observation times are 85.2 hours for ON source, and 80.8 hours for OFF source data. No significant excess of sub-TeV gamma rays has been found at 3 regions of the western X-ray lobe of SS433/W50 system. We have derived 99% confidence level upper limits to the fluxes of gamma rays and have set constraints on the strengths of the magnetic fields assuming the synchrotron/inverse-Compton model for the wide energy range of photon spectrum from radio to TeV. The derived lower limits are 4.3 microgauss for the center of the brightest X-ray emission region and 6.3 microgauss for the far end from SS433 in the western X-ray lobe. In addition, we suggest that the spot-like X-ray emission may provide a major contribution to the hardest X-ray spectrum in the lobe.

description: Grounded theory was first introduced more than 50 years ago, but researchers are often still uncertain about how to implement it. This is not surprising, considering that even the two pioneers of this qualitative design, Glaser and Strauss, have different views about its approach, and these are just two of multiple variations found in the literature. While studies using grounded theory in management research are becoming more popular, these are often mixed with the case study approach, or they provide contradictory guidelines on how to use it. The aim of this paper is to provide a clear guide for researchers who wish to use grounded theory in exploratory studies in management research. To support this goal, the methodology’s different terms and variations, as found in the literature, are also discussed. This study can support researchers using this methodology, but it is also useful for reviewers and examiners who wish to understand more about it and the different ways in which researchers have implemented it.
The New Agriculture: From Food Farms to Solar Farms

description: Across the United States, government agencies and energy developers are looking to agricultural land for development of renewable energy. One attraction of agricultural lands is that they are already relatively ecologically impaired compared with the previous solar development sites in the California and Arizona desert that have been a major source of concern for many environmental groups—and subject to expensive mitigation requirements under the Endangered Species Act. Renewable energy development pressures are accelerating the existing loss of agricultural land, heightening concerns about food security and the economic viability of agricultural communities. California farmland is at the center of this conflict. Suburban sprawl in California already leads to conversion of nearly 40,000 acres of agricultural land a year. Now, a new competitor has entered the scene: solar energy facilities. Both users compete for water, which is only becoming scarcer in the face of climate change and periodic drought. The pressures on California’s agricultural land have long inspired the state legislature and local governments to enact various measures to protect farmland and promote the business of agriculture. We examine the ways California’s Williamson Act (which provides tax benefits for agricultural land) and the California Environmental Quality Act (the state’s environmental review statute) have proven and not proven to be obstacles to taking agricultural land out of crop production and putting it into solar energy production. We demonstrate that current laws are neither protecting prime agricultural lands nor adequately creating conditions for evaluating the tradeoffs and alternatives when farmland—or ecologically sensitive habitat—is used for large-scale renewable energy development.

description: Objectives: We investigated whether the timing of hospital admission is associated with the risk of mortality for patients with COVID-19 in England, and the factors associated with a longer interval between symptom onset and hospital admission. Design: Retrospective observational cohort study of data collected by the COVID-19 Hospitalisation in England Surveillance System (CHESS). Data were analysed using multivariate regression analysis. Setting: Acute hospital trusts in England that submit data to CHESS routinely. Participants: Of 14 150 patients included in CHESS until 13 May 2020, 401 lacked a confirmed diagnosis of COVID-19 and 7666 lacked a recorded date of symptom onset. This left 6083 individuals, of whom 15 were excluded because the time between symptom onset and hospital admission exceeded 3 months. The study cohort therefore comprised 6068 unique individuals. Main outcome measures: All-cause mortality during the study period. Results: Timing of hospital admission was an independent predictor of mortality following adjustment for age, sex, comorbidities, ethnicity and obesity. Each additional day between symptom onset and hospital admission was associated with a 1% increase in mortality risk (HR 1.01; p<0.005). Healthcare workers were most likely to have an increased interval between symptom onset and hospital admission, as were people from Black, Asian and minority ethnic (BAME) backgrounds, and patients with obesity. Conclusion: The timing of hospital admission is associated with mortality in patients with COVID-19. Healthcare workers and individuals from a BAME background are at greater risk of later admission, which may contribute to reports of poorer outcomes in these groups. Strategies to identify and admit patients with high-risk and those showing signs of deterioration in a timely way may reduce the consequent mortality from COVID-19, and should be explored.

A set of dynamical simulations were performed for the gauge group SU(2) using the Wilson gauge action on 8^3x8 and 16^3x32 lattices. We considered a range of gluino masses (i.e., fifth dimension extents L_s=16-28 and input gluino mass values m_f=0.01-0.04) in order to perform chiral limit extrapolations of physical quantities. In these proceedings, we summarize our findings from a study of the Dirac spectrum and present new results for the topological charge on beta=2.3, 2.353 and 2.4 ensembles.

description: Objective: Endoscopic mucosal biopsies of primary gastric cancers (GCs) are used to guide diagnosis, biomarker testing and treatment. Spatial intratumoural heterogeneity (ITH) may influence biopsy-derived information. We aimed to study ITH of primary GCs and matched lymph node metastasis (LNmet). Design: GC resection samples were annotated to identify primary tumour superficial (PTsup), primary tumour deep (PTdeep) and LNmet subregions. For each subregion, we determined (1) transcriptomic profiles (NanoString ‘PanCancer Progression Panel’, 770 genes); (2) next-generation sequencing (NGS, 225 gastrointestinal cancer-related genes); (3) DNA copy number profiles by multiplex ligation-dependent probe amplification (MLPA, 16 genes); and (4) histomorphological phenotypes. Results: NanoString profiling of 64 GCs revealed no differences between PTsup1 and PTsup2, while 43% of genes were differentially expressed between PTsup versus PTdeep and 38% in PTsup versus LNmet. Only 16% of genes were differently expressed between PTdeep and LNmet. Several genes with therapeutic potential (eg IGF1, PIK3CD and TGFB1) were overexpressed in LNmet and PTdeep compared with PTsup. NGS data revealed orthogonal support of NanoString results with 40% mutations present in PTdeep and/or LNmet, but not in PTsup. Conversely, only 6% of mutations were present in PTsup and were absent in PTdeep and LNmet. MLPA demonstrated significant ITH between subregions and progressive genomic changes from PTsup to PTdeep/LNmet. Conclusion: In GC, regional lymph node metastases are likely to originate from deeper subregions of the primary tumour. Future clinical trials of novel targeted therapies must consider assessment of deeper subregions of the primary tumour and/or metastases as several therapeutically relevant genes are only mutated, overexpressed or amplified in these regions.

description: Let $E$ be a row-finite quiver and let $E_0$ be the set of vertices of $E$; consider the adjacency matrix $N'_E=(n_{ij})\in\Z^{(E_0\times E_0)}$, $n_{ij}=#\{$ arrows from $i$ to $j\}$. Write $N^t_E$ and 1 for the matrices $\in \Z^{(E_0\times E_0\setminus\Sink(E))}$ which result from $N'^t_E$ and from the identity matrix after removing the columns corresponding to sinks. We consider the $K$-theory of the Leavitt algebra $L_R(E)=L_\Z(E)\otimes R$. We show that if $R$ is either a Noetherian regular ring or a stable $C^*$-algebra, then there is an exact sequence ($n\in\Z$) \[ K_n(R)^{(E_0\setminus\Sink(E))}\stackrel{1-N_E^t}{\longrightarrow} K_n(R)^{(E_0)}\to K_n(L_R(E))\to K_{n-1}(R)^{(E_0\setminus\Sink(E))} \] We also show that for general $R$, the obstruction for having a sequence as above is measured by twisted nil-$K$-groups. If we replace $K$-theory by homotopy algebraic $K$-theory, the obstructions dissapear, and we get, for every ring $R$, a long exact sequence \[ KH_n(R)^{(E_0\setminus\Sink(E))}\stackrel{1-N_E^t}{\longrightarrow}KH_n(R)^{(E_0)}\to KH_n(L_R(E))\to KH_{n-1}(R)^{(E_0\setminus\Sink(E))} \] We also compare, for a $C^*$-algebra $\fA$, the algebraic $K$-theory of $L_\fA(E)$ with the topological $K$-theory of the Cuntz-Krieger algebra $C^*_\fA(E)$. We show that the map \[ K_n(L_\fA(E))\to K^{\top}_n(C^*_\fA(E)) \] is an isomorphism if $\fA$ is stable and $n\in\Z$, and also if $\fA=\C$, $n\ge 0$, $E$ is finite with no sinks, and $\det(1-N_E^t)\ne 0$.

A unified Eulerian variational framework for multiphase fluid-structure interaction
Creators: name: Mao, Xiaoyu
Publisher: name: University of British Columbia
Year: 2023

description: Multiphase fluid-structure interaction (FSI) involving multiphase flow and contact between immersed solids is omnipresent in numerous processes in nature, biology, and engineering applications. Examples include bio-inspired avian-aquatic vehicles, aneurysm and cardiovascular diseases in biomedical engineering, and marine vessels in ocean engineering. Of particular interest to the present study is the ice-going ships in the Arctic environment. Numerical simulation of this complex system involves modeling dynamics of disparate materials, evolving multiphase interfaces, and collisions between solids. The development of a novel three-dimensional multiphase and multiphysics computational framework based on unified continuum mechanics laws is the focus of the present dissertation. In the proposed numerical framework, we employ a fully Eulerian description for the continua of different phases, which facilitates topological changes of their interfaces during the evolution and contact processes. The interfaces and phase components are captured by the phase-field-based diffuse interface description. While the diffuse interface description circumvents the complexity of explicit interface reconstruction, it poses challenges in consistent interface transition and accurate geometric representation. To address these challenges, we developed an interface and geometry preserving phase-field method, which is the key contribution of this dissertation and lays the foundation for the success of the current framework in handling multiphase interfaces. With the phase components, we unify the mass and momentum conservations by phase-dependent interpolation. The kinematics of solid phases in an Eulerian frame of reference is resolved by evolving the left Cauchy-Green tensor. The unified Eulerian framework for two-phase and multiphase FSI is implemented in a partitioned-block iterative manner within the in-house 3D parallel variational multiphysics solver. The solver is systematically explored for a variety of cases of two-phase flow with surface tension effect, single-phase FSI, multiphase FSI, and contact of immersed deformable solids. The study is concluded by a 3D demonstration of ice-going ships sailing across floating ice floes. The unified Eulerian variational framework with a parallel implementation based on the novel interface and geometry preserving phase-field method provides a general and robust approach for investigating a wide range of multiphase FSI problems.
Aviation, Carbon, and the Clean Air Act

description: Can CAA regulation achieve aviation emissions regulations significant enough to establish equivalency with E.U. policy while remaining cost-effective and politically acceptable? Fully answering this question requires judgments about the range of options realistically available to the EPA in the current U.S. political environment and about the range of policies the E.U. would consider “equivalent”—judgments that would be, at best, informed guesses. But the core part of the question is legal. Specifically, what tools are available to the Agency under the CAA to regulate aviation emissions, and how might they be used for GHGs? This Article is an attempt to answer that core legal question. The Agency’s powers to address aviation GHGs under the Act have not been thoroughly studied. A few court decisions, EPA documents, and petitions to the Agency have looked at the issue or aspects of it, but none is a comprehensive assessment. One relatively brief scholarly treatment exists, and although it is a useful introduction to many of the relevant issues, much has changed since it was published in 2009. This Article also reaches different conclusions on several points, as noted below. EPA regulation of aviation GHG emissions under the CAA was the subject of recent litigation. However, that litigation concerned whether the Agency must regulate such emissions. This threshold issue is relevant, but both parties to the litigation agree that the EPA has authority to regulate aviation emissions. Moreover, the suit did nothing to clarify how the Agency could regulate, whether it chooses to do so or is compelled. It is this latter question that this Article seeks to answer. In short, the CAA does provide the EPA with substantial authority and flexibility to regulate aviation GHG emissions. Doing so will require the Agency to depart from its traditional use of this authority, but neither the statute nor international law appears to stand in the way. The Act further appears to give the Agency authority to implement smart regulation in the form of performance standards that give compliance flexibility to industry and perhaps allow limited use of market-based mechanisms. Political and administrative challenges remain for the EPA, however.

We obtained these using the CRIRES spectrometer on the VLT. The formation and evolution of the Milky Way bulge can be constrained by studying elemental abundances of bulge stars. Due to the large and variable visual extinction in the line-of-sight towards the bulge, an analysis in the near-IR is preferred.

description: The long-term habitability of Earth-like planets requires low orbital eccentricities. A secular perturbation from a distant stellar companion is a very important mechanism in exciting planetary eccentricities, as many of the extrasolar planetary systems are associated with stellar companions. Although the orbital evolution of an Earth-like planet in a stellar binary is well understood, the effect of a binary perturbation to a more realistic system containing additional gas giant planets has been very little studied. Here we provide analytic criteria confirmed by a large ensemble of numerical integrations that identify the initial orbital parameters leading to eccentric orbits. We show that an extra-solar earth is likely to experience a broad range of orbital evolution dictated by the location of a gas-giant planet, necessitating more focused studies on the effect of eccentricity on the potential for life.

A Triple Bottom Line for Electric Utility Regulation: Aligning State-Level Energy, Environmental, and Consumer Protection Goals

Publisher: name: Columbia Journal of Environmental Law
Year: 2013

description: Aligning state policy goals can help keep the lights on and electricity prices affordable while also promoting investments in clean energy technologies and efficiency measures that protect public health and the environment. This Article explores the opportunities and challenges to aligning state energy, environmental, and consumer protection goals within the current regulatory system, and proposes a “triple bottom line” (“TBL”) approach to state utility regulation to achieve this alignment. The original TBL concept encourages businesses and governments to measure value by considering environmental and social dimensions in addition to fiscal considerations. By comparison, the TBL approach for electric utility regulation proposed here aims to harmonize existing state policy goals of ensuring: (1) affordable electricity; (2) reliable electricity; and (3) protection of public health and the environment. Specifically, it allows officials across state governments to consider how their roles affect all three TBL pillars, thereby enabling informed decision making and comprehensive problem solving to improve outcomes across all three goals.

description: Objectives: To systematically review the evidence base for a systems approach to healthcare design, delivery or improvement. Design: Systematic review with meta-analyses. Methods: Included were studies in any patients, in any healthcare setting where a systems approach was compared with usual care which reported quantitative results for any outcomes for both groups. We searched Medline, Embase, HMIC, Health Business Elite, Web of Science, Scopus, PsycINFO and CINAHL from inception to 28 May 2019 for relevant studies. These were screened, and data extracted independently and in duplicate. Study outcomes were stratified by study design and whether they reported patient and/or service outcomes. Meta-analysis was conducted with Revman software V.5.3 using ORs—heterogeneity was assessed using I2 statistics. Results: Of 11 405 records 35 studies were included, of which 28 (80%) were before-and-after design only, five were both before-and-after and concurrent design, and two were randomised controlled trials (RCTs). There was heterogeneity of interventions and wide variation in reported outcome types. Almost all results showed health improvement where systems approaches were used. Study quality varied widely. Exploratory meta-analysis of these suggested favourable effects on both patient outcomes (n=14, OR=0.52 (95% CI 0.38 to 0.71) I2=91%), and service outcomes (n=18, OR=0.40 (95% CI 0.31 to 0.52) I2=97%). Conclusions: This study suggests that a systems approaches to healthcare design and delivery results in a statistically significant improvement to both patient and service outcomes. However, better quality studies, particularly RCTs are needed. PROSPERO registration number CRD42017065920.
Why the Commercial Speech Doctrine Will Prove Toxic to the USDA National Organic Program
Creators: name: Heyman, Todd S.
Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: This Article argues that the Supreme Court has expanded commercial speech rights too far. The current Court increasingly appears to view the government's power to regulate commercial speech as limited to only proscribing false or misleading commercial speech. Any attempt by the government to restrict truthful commercial speech, even if potentially misleading, is generally treated as unjustified paternalism in violation of the First Amendment. The evolving jurisprudence threatens reasonable economic regulations that restrict speech for important and non-paternalistic reasons. To make this case, this Article explores how the evolving commercial speech doctrine could invalidate the food-labeling regime established by the Organic Foods Production Act of 1990 ("OFPA") and its implementing regulations. That regulatory regime, often referred to as the National Organic Program ("NOP"), generally prohibits representing food as "organic" unless a United States Department of Agriculture ("USDA") licensed inspector has certified that the food was produced consistent with OFPA's implementing regulations. The National Organic Program: (1) provides assurance to the consumer that the product is indeed organic; (2) sets clear standards to define the organic market so that producers can enjoy a price premium for food produced consistent with those standards; and (3) incentivizes producers, through the price premium, to convert from conventional to organic production practices, resulting in substantial environmental benefits. Although the regulations facilitate the creation and growth of an organic market with integrity, the regulations are vulnerable to a First Amendment challenge because they restrict the use of the term "organic" to a very limited set of circumstances.

description: We present distance determinations for two Local Group dwarf spheroidal galaxies, Carina and Fornax, based on the near-infrared magnitudes of the tip of the red giant branch (TRGB). For Carina we derive true distance moduli of 20.09 and 20.13 mag in the J and K bands, respectively, while for Fornax the same distance modulus of 20.84 mag was derived in both filters. The statistical errors of these determinations are of order 0.03-0.04 mag, whereas the systematic uncertainties on the distances are 0.12 mag in the J band and 0.14 mag in the K band. The distances obtained from the near-infrared TRGB method in this paper agree very well with those obtained for these two galaxies from optical calibrations of the TRGB method, their horizontal branches, RR Lyrae variables, and the near-infrared magnitudes of their red clumps.

Missing the Forest and the Trees: Lost Opportunities for Federal Land Exchanges
Creators: name: Miller, Scott K.
Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: For any land exchange carried out by the Forest Service or the Bureau of Land Management (“Agencies”), federal law generally requires the Agencies to ensure that “the public interest will be well served by making that exchange.” To do so, the Agencies must consider the fate of the land they convey and how that is likely to affect the public interest. To help control the fate of the land they convey and the adverse impacts it may have on the public interest, the Agencies’ regulations mandate that they “reserve such rights or retain such interests as are needed to protect the public interest.” Nevertheless, the Agencies’ internal policies all but prohibit their employees from carrying out that mandate. As a result, the Agencies are missing opportunities to better serve both the public’s interests and their own. By including covenants, easements, or other restrictions on the lands they convey, the Agencies can more accurately and confidently determine the future use of the land. Doing so can have substantial benefits not only for the public interest, but also for the efficiency and defensibility of the Agencies’ land exchange processes. A new policy is necessary, and its lessons will have broader applicability to dozens of federal agencies and the billions of dollars of real property transactions in which they engage. This Article begins with a short case study that starkly illustrates the Agencies’ practices and their significant shortcomings. Following the case study, the Prologue continues with a more thorough introduction to the subject and the thesis that is explored. Parts II and III describe the prominent features of the physical and historic landscape within which the Agencies’ land exchange programs operate—including the Agencies’ land management imperatives and their public interest lapses—while Parts IV and V explore the statutory, regulatory, and judicial landscape. The discussion demonstrates the significant responsibilities the Agencies have to guide the future use of the land they convey when necessary to serve the public interest. Part VI explores the substantial transactional and opportunity benefits the Agencies miss by failing to consider and strategically employ restrictions on the lands they convey, and Part VII critiques the Agencies’ arguments that have led to these missed opportunities. Finally, this Article suggests a framework for developing new policies that will better serve the Agencies and the public.

Introduction: Food insecurity can negatively impact adherence and receipt of high-quality cancer care. The purpose of the study was to (1) compare the prevalence of COVID-19-associated food insecurity by cancer history and (2) examine determinants associated with COVID-19-related food insecurity among cancer survivors. Methods: We used nationally representative data from the 2020 COVID-19 Household Impact Survey (n=10,760). Our primary exposure was participants' self-report of a cancer diagnosis (n=854, 7.1%). Primary outcomes of food insecurity were categorized by the following questions: "We worried our food would run out before we got money to buy more" or "The food that we bought just didn't last, and we didn't have money to get more"; respondents were categorized as food insecure if they chose often true or sometimes true. Multivariable Poisson regression was used to identify demographic determinants of food insecurity among cancer survivors. Results: Thirty-two percent of cancer survivors were food insecure. Cancer survivors 30-44 years of age and those ≥60 years of age were more likely to report being food insecure compared to respondents without a history of cancer, respectively (30-44 years, 59.9% vs. 41.2% p=0.01, ≥60 years 27.2% vs. 20.2%, p=0.01). Cancer survivors without a high school diploma were more likely to report food insecurity compared to adults with no history of cancer (87.0% vs. 64.1%, p=0.001). In multivariable models, uninsured cancer survivors (adjusted prevalence ratio [aPR] aPR: 2.39, 95% CI: 1.46-3.92) and those on Medicaid (aPR: 2.10, 95% CI: 1.40-3.17) were also more likely to report being food insecure. Conclusion: Food insecurity during the COVID-19 pandemic is vast, but disparities persist. Among cancer survivors, differences in food insecurity were observed by age and socio economic status. Cancer survivors experiencing food insecurity more frequently reported mental health symptoms of depression, loneliness, and hopelessness compared to those who were food secure.
Examining Tribal Environmental Law

description: Since the revolution of environmental law began roughly forty years ago, scholars have wrestled with the complex interactions of the states and federal government, but they have largely ignored tribal governments. Although some scholarship exists regarding the suggested development of tribal environmental law, little is known about the extent to which tribes nationwide have enacted such laws. This Article fills that vacuum by taking a first look at existing tribal environmental law and exploring the laws of one tribal nation that has enacted several environmental laws. The Article also proposes some initial norms to guide the development of tribal environmental law.

description: O capitalismo agroindustrial tem produzido uma realidade do campo que tem estabelecido condições de vida para o campesinato brasileiro de precarização e exploração pela determinação do que produzir, em que condições produzir, a quantidade e qualidade da produção, para quem comercializar e a que preço vender. No entanto, em fins de 2003, surge o Programa de Aquisição de Alimentos (PAA) que permitiu ao campesinato brasileiro visualizar uma outra realidade. Sem conseguir reverter ou estancar o processo de avanço do capitalismo agroindustrial, o PAA tem proporcionado ao campesinato estabelecer novas estratégias de resistência e luta com vistas a se colocarem enquanto atores do desenvolvimento brasileiro. Desta forma, neste artigo, discuto e apresentado dados que demonstram a importância do PAA para o reestabelecimento do modo de vida do campesinato, e em que medida o programa conseguiu estabelecer novas pautas e espaços de resistência para a condição camponesa no Brasil.
Effect of Torque Tube Reflection on Shading and Energy Yield in Bifacial Photovoltaic Systems

description: Bifacial photovoltaic (PV) modules have greater energy yield than traditional monofacial modules because they convert front and rear incident irradiance to electrical energy. Single-axis tracking systems can further increase energy yield and reduce the levelized cost of energy by rotating the modules throughout the day. However, racking elements in tracking systems introduce both shade and reflections on the rear face, increasing irradiance nonuniformity and fostering further electrical mismatch that reduces module power. The impact of racking, particularly that of the torque tube which spans the middle of the rear collector surface, must be accurately quantified in energy yield predictions to increase stakeholder confidence, and hasten the adoption of tracked bifacial modules. Isolating the torque-tube-reflected irradiance incident on the modules is crucial for this work. This is achieved by implementing arbitrary two-dimensional (2D) irradiance sampling on a module under test in bifacial_radiance, a ray tracing bifacial PV model, and taking the difference in rear irradiance profiles for simulations with a reflective and an absorptive torque tube at each timestamp. We calculate the TT reflection for the central one-in-portrait (1P) and two-in-portrait (2P) modules on horizontal single-axis trackers over hourly timestamps in a typical meteorological year in Livermore, California, USA. We introduce the TT reflection 2D irradiance profiles as additional light sources in DUET to quantify the TT reflection's impact on irradiance, electrical mismatch, and energy yield, as well as an incidence angle modifier's impact on TT reflection. We analyze the TT reflection based on sun zenith and diffuse fraction to group consistent illumination conditions across the year. We identify that TT reflection reduces electrical mismatch by partially offsetting TT shading, and increases annual energy yield by 0.11% and 0.18% in our particular 1P and 2P systems. While the overall impact of TT reflection is greater in the 2P system due to direct beam light incident on the TT, the TT reflection's greatest instantaneous relative contribution to total energy yield is larger for the 1P system, at high diffuse fractions and sun zeniths. For future work, we recommend validating simulation results with and without TT reflection against experimental data. The simulation method used for isolating the TT reflection may also be repurposed to help inform new TT designs that minimize electrical mismatch. Finally, instead of relying on bifacial_radiance to isolate the TT reflection, we recommend incorporating the TT as a Lambertian reflective surface in 3D view factor models with detailed shading for further TT reflection simulations.
Greenwashing 2.0

Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: This Article argues that this period of unprecedented clean tech innovation requires a new paradigm for thinking about greenwashing. Specifically, it is essential that the paradigm shift from almost exclusive focus on B-to-C environmental advertising directed to individual green consumers to an expanded and more nuanced view that also includes B-to-B representations made to commercial consumers. This new paradigm would define greenwashing expansively to include any false or misleading claim regarding the environmental benefit of a product, service, or business practice. Its analysis should not be limited to cases brought by or on behalf of individual consumers, but should also contemplate legal actions by and on behalf of green commercial consumers. Changing the greenwashing paradigm in this way will reflect the commercial realities of the clean tech revolution, and will provide the broader vantage point necessary to identify instances of greenwashing and understand its prevalence and effects.

description: Objectives: Kidney cancer has been identified as a disease for which screening might provide significant benefit for patients. The aim of this study was to understand in detail the facilitators and barriers towards uptake of a future kidney cancer screening programme, and to compare these across four proposed screening modalities. Design: An online survey including free-text responses. Setting: UK Participants: 668 adults Primary and secondary outcome measures: The survey assessed participants’ self-reported intention to take-up kidney cancer screening with four different test methods (urine test, blood test, ultrasound scan and low-dose CT). We conducted thematic analysis of 2559 free-text comments made within the survey using an inductive approach. Results: We identified five overarching themes that influenced screening intention: ‘personal health beliefs’, ‘practicalities’, ‘opinions of the test’, ‘attitudes towards screening’ and ‘cancer apprehension’. Overall, participants considered the tests presented as simple to complete and the benefits of early detection to outweigh any drawbacks to screening. Dominant facilitators and barriers varied with patterns of intention to take up screening across the four tests. Most intended to take up screening by all four tests, and for these participants, screening was seen as a positive health behaviour. A significant minority were driven by practicalities and the risks of the tests offered. A smaller proportion intended to reject all forms of screening offered, often due to fear or worry about results and unnecessary medical intervention or a general negative view of screening. Conclusions: Most individuals would accept kidney cancer screening by any of the four test options presented because of strong positive attitudes towards screening in general and the perceived simplicity of the tests. Providing information about the rationale for screening in general and the potential benefits of early detection will be important to optimise uptake among uncertain individuals.
