Quotas, spillovers, and the transfer paradox in an economy with tourism

This paper examines the welfare implications of quotas for an economy that is small in terms of traditionally traded goods and has monopoly power over the trade of goods consumed by tourists. Inbound tourism converts local nontraded goods into tradable goods, creating a tourism terms-of-trade effect for the touristreceiving economy. Through this effect, quotas result in a spillover to the nontraded sector. Hence, in the presence of tourism, the traditional free-trade prescription for the small open economy is no longer valid. This lends support to the setting of import quotas. Using the optimal quota as a benchmark, we further examine the welfare effect of tied aid. If tied aid brings about an excessive supply of importable goods, then the transfer paradox of the immiserization of the tourist- receiving economy may occur.

Paradox lost: variable colour-pattern geometry is associated with differences in movement in aposematic frogs

Aposematic signal variation is a paradox: predators are better at learning and retaining the association between conspicuousness and unprofitability when signal variation is low. Movement patterns and variable colour patterns are linked in non-aposematic species: striped patterns generate illusions of altered speed and direction when moving linearly, affecting predators' tracking ability; blotched patterns benefit instead from unpredictable pauses and random movement. We tested whether the extensive colour-pattern variation in an aposematic frog is linked to movement, and found that individuals moving directionally and faster have more elongated patterns than individuals moving randomly and slowly. This may help explain the paradox of polymorphic aposematism: variable warning signals may reduce protection, but predator defence might still be effective if specific behaviours are tuned to specific signals. The interacting effects of behavioural and morphological traits may be a key to the evolution of warning signals. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

Sisyphus and self-management : the chronic condition self-management paradox

Chronic condition self-management is promoted internationally as not only a possible solution to the health problems of our increasingly chronically ill and ageing population, but as part of a new wave of consumer-led and volunteer-managed health care initiatives. Consumers are now indicating that they want to be more involved in the management of their lives and their health care options, while, especially in rural and smaller communities in Australia, a shortage of clinicians means that health care is rapidly changing. This emphasis on self-management raises crucial questions about where consumer action and control in health care should end and where clinical and medical intervention might begin. Hence, as in the case of Sisyphus and his rock, the self-management process is a difficult and demanding one that poses major challenges and loads for health system reformers and represents a struggle in which new difficulties are constantly emerging. This paper examines some implications of new self-management approaches to chronic illness from an ideological perspective and highlights key elements that underpin the effort to promote health-related lifestyle change. While peer-led self-management programs may assist certain individuals to live engaged and meaningful lives, the essential social and economic determinants of health and wellbeing mean that these programs are not the answer to our urgent need for major reform in the health care arena. Rather, self-management, from an ideological perspective, represents a minor adjustment to the fabric of our health system.

Can Peto's paradox be used as the null hypothesis to identify the role of evolution in natural resistance to cancer? A critical review

BACKGROUND: Carcinogenesis affects not only humans but almost all metazoan species. Understanding the rules driving the occurrence of cancers in the wild is currently expected to provide crucial insights into identifying how some species may have evolved efficient cancer resistance mechanisms. Recently the absence of correlation across species between cancer prevalence and body size (coined as Peto's paradox) has attracted a lot of attention. Indeed, the disparity between this null hypothesis, where every cell is assumed to have an identical probability to undergo malignant transformation, and empirical observations is particularly important to understand, due to the fact that it could facilitate the identification of animal species that are more resistant to carcinogenesis than expected. Moreover it would open up ways to identify the selective pressures that may be involved in cancer resistance. However, Peto's paradox relies on several questionable assumptions, complicating the interpretation of the divergence between expected and observed cancer incidences. DISCUSSIONS: Here we review and challenge the different hypotheses on which this paradox relies on with the aim of identifying how this null hypothesis could be better estimated in order to provide a standard protocol to study the deviation between theoretical/theoretically predicted and observed cancer incidence. We show that due to the disproportion and restricted nature of available data on animal cancers, applying Peto's hypotheses at species level could result in erroneous conclusions, and actually assume the existence of a paradox. Instead of using species level comparisons, we propose an organ level approach to be a more accurate test of Peto's assumptions. SUMMARY: The accuracy of Peto's paradox assumptions are rarely valid and/or quantifiable, suggesting the need to reconsider the use of Peto's paradox as a null hypothesis in identifying the influence of natural selection on cancer resistance mechanisms.

The Cutopia Paradox: anthropomorphism as entertainment

An infant chimpanzee, dressed in riotous checks, bowtie and braces, cradled in human arms while it regards a camera, is perhaps further from us than a tiger lurking in the deepest jungle. Anthropomorphic sentiment negates empathy, blinding us to the real animal behind the “character.” The engaging creature we imagine we’d like to hold and protect is the product, most likely, of violent separation and trauma, stolen in order to bring us this enjoyment. We read the comical face, celebrating what appear to be traces of commonality; but the eyes of the small creature are windows to a realm we cannot comprehend. By following the life of a single chimpanzee, Cobby, the oldest chimp in captivity in the USA, this paper will explore our attraction to cuteness via the lens of chimpanzees in entertainment, regarding it as an intersection of emotion and metaphor that is potentially devastating to animals. We will argue that anthropomorphic sentiment and construction misdirects empathy away from the plight of real animals, and that every animal has the right to be acknowledged as a unique individual, rather than a generic entity. Animals that have been born in captivity and, to a lesser extent, those that have been extracted from the wild in infancy, can be seen as trapped between worlds. There exists, therefore, a hybrid population of animals that lives amongst us, amnesiacs dependent upon human compassion, or conversely, prey to its absence.

The presidential persona paradox of Barack Obama : man of peace or war president?

On a wave of hope and rousing talk of building global bridges, President Barack Obama won office in 2008, in part on a pledge to end the wars in Afghanistan and Iraq and to close the Guantanamo Bay detention facility. In contrast to his predecessor, who launched America into long, costly and ineffectual wars, Obama was seen to be more of a dove than a hawk. However, at the end of his two-term tenure America has been in a state of foreign belligerence for all eight years, making Obama the longest serving U.S. war president in history.The political persona of Obama as a dove originated with his opposition to the 2003 intervention in Iraq while he was still a senator. This was then cemented early in his presidency with his 2009 speech in Cairo, which seemed to signal a profound and optimistic realignment of America’s intentions towards the Middle East and its peoples. This speech was a watershed in defining his political persona and was instrumental in his being the only U.S. president to be awarded a Nobel Peace Prize while still in office. However, during his term the underlying political landscape of the Middle East changed significantly, with the withdrawal from then return to Iraq, the nuclear agreement with Iran, the increasingly chaotic legacy of the Arab Spring, the continued impasse of the Israel-Palestinian peace, the disintegration of Yemen and Libya and the rise of the Islamic State as the new threat in the political vacuum of northern Iraq and eastern Syria, and a resurgent Russian role in the region. All of these have provided novel challenges to Washington and a president attempting to live up to the positivity of his early days in office.At the end of his presidency Obama is faced with a public burned by the disappointments of the Iraq and Afghanistan campaigns and the new entanglements in the Middle East. This paper seeks to offer insights into the juxtaposition of Obama’s political persona and reality, as well as exploring what his political legacy might really be.

Redistribution, recognition and representation: working against pedagogies of indifference

This paper reports on an Australian government-commissioned research study that documented classroom pedagogies in 24 Queensland schools. The research created the model of ‘productive pedagogies’, which conjoined what Nancy Fraser calls a politics of redistribution, recognition and representation. In this model pedagogies are differentiated to support the role of schooling as a positional good, a good in itself, and a good towards the betterment of the broader social world. In contrast with the model’s intentions, the pedagogies mapped in the study’s classrooms lacked differentiation; indeed, they reflected ‘pedagogies of indifference’ and were seen as producing and legitimising social inequalities. The paper theorises the redistributive, recognitive and representative justice possibilities of ‘productive pedagogies’ towards more equitable outcomes for marginalised students. The paper justifies its reprising of this research in light of the contemporary policy emphasis on teaching quality, the reductive impact on pedagogies of high-stakes testing, and the context of growing inequality which limits the potential effects of schools and teacher pedagogies.

Refugee education and justice issues of representation, redistribution and recognition

This paper examines justice issues of representation, redistribution and recognition within a specialised secondary school for immigrant and refugee students in Queensland, Australia. Fraser’s three-dimensional model of justice – towards the ideal of ‘participatory parity’ – is drawn on to analyse interview data gathered from a study that sought to identify productive approaches to addressing cultural diversity. Through these lenses, injustices created by mainstream/dominant discourses within and beyond the school are highlighted. The paper details the school’s efforts to support greater equity for these students through educator advocacy, critically reflective practice and a centring of students’ perspectives. The significance of educators identifying and challenging the limits and exclusions of these discourses to support these efforts is highlighted. Fraser’s theorising is presented as useful in capturing, understanding and addressing justice and marginality in schools amid the broader social context where matters of justice are characterised by uncertainty, complexity and contention.
