Zarin v. Commissioner: The Continuing Validity of Case Law Exceptions to Discharge of Indebtedness Income

This Casenote examines Zarin v. Commissioner, decided by the United States Court of Appeal for the Third Circuit in 1990. This case considered exceptions to the general rule that income from the discharge of indebtedness is included as gross income under the Internal Revenue Code. The court found these exceptions valid. This Casenote argues that the court\u27s reasoning in Zarin v. Commissioner assures that its decision will have implications well beyond the facts of the case. The author also suggests that these exceptions are both reinforced and expanded by this case. He concludes that the result of this case is a more flexible approach to disputed liability issues, which should engender more rational decisions in the tax law area

Improved high pressure turbine shroud

A new high pressure turbine shroud material has been developed from the consolidation of prealloyed powders of Ni, Cr, Al and Y. The new material, a filler for cast turbine shroud body segments, is called Genaseal. The development followed the identification of oxidation resistance as the primary cause of prior shroud deterioration, since conversion to oxides reduces erosion resistance and increases spalling under thermal cycled engine conditions. The NICrAlY composition was selected in preference to NIAL and FeCRALY alloys, and was formulated to a prescribed density range that offers suitable erosion resistance, thermal conductivity and elastic modulus for improved behavior as a shroud

A new direction for water management? Indigenous nation building as a strategy for river health

© 2017 by the author(s). Indigenous involvement in Australian water management is conventionally driven by a top-down approach by nonIndigenous government agencies, that asks “how do we engage Indigenous people?” and has culminated in the ineffective “consult” and “service delivery” processes evident in mainstream water management planning. This is a hopeful paper that identifies the critical importance of a “nation-based” approach for effective Indigenous engagement in water planning and policy through the work undertaken by the Ngarrindjeri Regional Authority (NRA) in the Murray Futures program. The NRA is an Indigenous government in the “settled-south” of Australia. Over past decades, the NRA has developed a range of political technologies that act as tools for redeveloping Ngarrindjeri Nationhood after colonial disempowerment and dispossession. These tools enable better collaboration with nonIndigenous governments, especially in natural resource management policy and practice. In turn, this has better enabled the NRA to exercise a decision-making and planning authority over the lands and waters in its jurisdiction, therefore, more effectively exercising its ongoing duty of care as Country. This paper presents a case study of the Sugar Shack Complex Management Plan, codeveloped by the NRA and the South Australian Government in 2015, to demonstrate the benefits that accrue when Indigenous nations are resourced as authorities responsible for reframing water management and planning approaches to facilitate the equitable collaboration of Indigenous and nonIndigenous worldviews. As a marker of the success of this strategy, the Ngarrindjeri Yarluwar-Ruwe Program, in partnership with the South Australian government, recently won the Australian Riverprize 2015 for delivering excellence in Australian river management

Indigenous sovereignties: relational ontologies and environmental management

© 2019 Institute of Australian Geographers Indigenous nations have always and continue to assert their sovereignties to resist colonialism. This paper makes explicit the ways in which environmental management has been and continues to act as a tool of colonialism, particularly by privileging Western science, institutions, and administrative procedures. We argue that to decolonise environmental management, it is crucial to understand and challenge the power relations that underlie it—asking who makes decisions and on what worldview those decisions are based. Indigenous ways of being deeply challenge the foundations of environmental management and the colonising power structures that underlie it, and invite further thought about posthuman and relational ontologies. We provide a range of case studies that showcase the role of Indigenous nations in redefining and reimagining environmental management based on Indigenous sovereignties, knowledges, and ways of being. The case studies emphasise the crucial connection between Indigenous decision-making authority and self-governance for the enhanced protection and health of the environment. We argue that Indigenous agency, grounded in Indigenous governance and sovereignties, is driving innovation and decolonising environmental management by making space for new ways of thinking and being “in place”

Multivariate phase space reconstruction by nearest neighbor embedding with different time delays

A recently proposed nearest neighbor based selection of time delays for phase space reconstruction is extended to multivariate time series, with an iterative selection of variables and time delays. A case study of numerically generated solutions of the x- and z coordinates of the Lorenz system, and an application to heart rate and respiration data, are used for illustration.Comment: 4 pages, 3 figure

Characterizing the recovery trajectories of knee range of motion for one year after total knee replacement

DESIGN: Retrospective analysis of routinely collected clinical data. OBJECTIVE: This study modeled the recovery in knee flexion and extension range of motion (ROM) over 1 year after total knee replacement (TKR). BACKGROUND: Recovery after TKR has been characterized for self-reported pain and functional status. Literature describing target knee ROM at different follow-up periods after TKR is scarce. METHODS: Data were extracted for patients who had undergone TKR at a tertiary care hospital at 2, 8, 12, 26, and 52 weeks after TKR. A linear mixed-effects growth model was constructed that investigated the following covariates age, sex, pre-TKR range, body mass index, duration of symptoms, and their interaction with weeks post TKR. RESULTS: Of the 559 patients included (age 64.8 ± 8.5 years), 370 were women and 189 were men. Knee ROM showed the greatest change during the first 12 weeks after TKR, plateauing by 26 weeks. For an average patient, knee flexion increased from approximately 100º 2 weeks post TKR to 117º 52 weeks post TKR. Knee extension increased from approximately 3º knee flexion 2 weeks post TKR to 1º flexion 52 weeks post TKR. CONCLUSIONS: The results showed that the maximum gains in knee ROM should be expected within the first 12 weeks with small changes occurring up to 26 weeks after TKR. In addition, age and presurgery knee ROM are associated with the gains in knee ROM and should be factored into the estimation of expected knee ROM at a given follow-up interval after TKR

Measuring Information Transfer

An information theoretic measure is derived that quantifies the statistical coherence between systems evolving in time. The standard time delayed mutual information fails to distinguish information that is actually exchanged from shared information due to common history and input signals. In our new approach, these influences are excluded by appropriate conditioning of transition probabilities. The resulting transfer entropy is able to distinguish driving and responding elements and to detect asymmetry in the coupling of subsystems.Comment: 4 pages, 4 Figures, Revte

Webteaching: sequencing of subject matter in relation to prior knowledge of pupils

Two experiments are discussed in which the sequencing procedure of webteaching is compared with a linear sequence for the presentation of text material.\ud \ud In the first experiment variations in the level of prior knowledge of pupils were studied for their influence on the sequencing mode of text presentation. Prior knowledge greatly reduced the effect of the size of sequencing procedures.\ud \ud In the second experiment pupils with a low level of prior knowledge studied a text, following either a websequence or a linear sequence. Webteaching was superior to linear teaching on a number of dependent variables. It is concluded that webteaching is an effective sequencing procedure in those cases where substantial new learning is required

Barriers and facilitators for health professionals referring Aboriginal and Torres Strait Islander tobacco smokers to the Quitline

Objective: To examine the barriers and facilitators among health professionals to providing referrals to Quitline for Aboriginal and Torres Strait Islander clients who smoke. Methods: A brief online survey, based on the Theoretical Domains Framework, was completed by 34 health professionals who work with Aboriginal and Torres Strait Islander people in South Australia and the Northern Territory. Results: Respondents who frequently made referrals had higher domain scores than less frequent referrers for ‘Skills and knowledge’ (M=4.44 SD=0.39 vs. M=4.09 SD=0.47, p<0.05) and ‘beliefs about capabilities’ (M=4.33 SD=0.44 vs. M=3.88 SD=0.42, p<0.01). Barriers to providing referrals to Quitline were lack of client access to a phone, cost of a phone call, preference for face-to-face interventions, and low client motivation to quit. Conclusions: Health professionals working with Aboriginal and Torres Strait Islander clients should be supported to build their skills and confidence to provide referrals to Quitline and other brief cessation interventions. Building capacity for face-to-face support locally would be beneficial where phone support is not preferable. Implications for public health: Engaging with health professionals who work with Aboriginal and Torres Strait Islander people to increase referrals to Quitline is strategic as it builds on their existing capacity to provide cessation support.Kimberley Martin, Joanne Dono, Nathan Rigney, Joanne Rayner, Alana Sparrow, Caroline Miller, Andrea Mckivett, Kerin O'Dea, David Roder, Jacqueline Bowde
