A clarification of the Goodwin model of the growth cycle

We show that there is a difficulty in the original Goodwin model which isalso found in some more recent applications. In it both the labour share and theproportion employed can exceed unity, properties which are untenable. However, weshow that the underlying dynamic structure of the model can be reformulated toensure that these variables cannot exceed unity. An illustrative example extends theoriginal model, and we argue it is both plausible and satisfies the necessary unit boxrestrictions.

Soil erosion between Birchs Inlet and Elliott Bay, southwestern Tasmania

Organic soils (peats) in areas of southwestern Tasmania have been degraded by fire and subsequent erosive processes, area affected by frequent firing has been examined and mapped to demonstrate the extent and severity of erosion. A high fire frequency is likely to lead to increased peat loss, a decrease in height and cover of vegetation and ultimately to areas denuded of peat. Implications for land management are discussed

Within-trio tests provide little support for post-copulatory selection on MHC haplotypes in a free-living population

Sexual selection has been proposed as a force that could help maintain the diversity of major histocompatibility complex (MHC) genes in vertebrates. Potential selective mechanisms can be divided into pre-copulatory and post-copulatory, and in both cases, the evidence for occurrence is mixed, especially in natural populations. In this study, we used a large number of parent-offspring trios that were diplotyped for MHC class II genes in a wild population of Soay sheep (Ovis aries) to examine whether there was within-trio post-copulatory selection on MHC class II genes at both the haplotype and diplotype levels. We found there was transmission ratio distortion of one of the eight MHC class II haplotypes (E) which was transmitted less than expected by fathers, and transmission ratio distortion of another haplotype (A) which was transmitted more than expected by chance to male offspring. However, in both cases, these deviations were not significant after correction for multiple tests. In addition, we did not find any evidence of post-copulatory selection at the diplotype level. These results imply that, given known parents, there is no strong post-copulatory selection on MHC class II genes in this population

Contemporary medical television and crisis in the NHS

This article maps the terrain of contemporary UK medical television, paying particular attention to Call the Midwife as its centrepiece, and situating it in contextual relation to the current crisis in the NHS. It provides a historical overview of UK and US medical television, illustrating how medical television today has been shaped by noteworthy antecedents. It argues that crisis rhetoric surrounding healthcare leading up to the passing of the Health and Social Care Act 2012 has been accompanied by a renaissance in medical television. And that issues, strands and clusters have emerged in forms, registers and modes with noticeable regularity, especially around the value of affective labour, the cultural politics of nostalgia and the neoliberalisation of healthcare

Emerging Best Practices in International Atmospheric Trust Case Law

With climate change litigation proliferating throughout the world, a substantial body of case law is emerging. As part of a project of the IUCN World Commission on Environmental Law\u27s Climate Change Specialist Group, this Article, a version of which will be included in a “Judicial Handbook on Climate Litigation,” explains the public trust doctrine’s influence on climate change litigation internationally. We select what we view as judicial “best practices” as a kind of restatement of international atmospheric trust law in 2022. International atmospheric trust law is at the forefront of many best practices, as state and federal courts in the United States have fettered the public trust doctrine’s development by erecting procedural hurdles like standing and political question doctrines. On the other hand, international courts do not suffer from these procedural limitations, allowing them to reach the merits of public trust claims in the context of climate change. This Article explains these developments in an effort to synthesize the rapidly developing case law
