Coral reefs provide substantial benefits to humans by generating biologically diverse ecosystems and reducing coastal hazards. However, in recent years, mass mortality of coral reefs due to bleaching has been witnessed in the ocean worldwide. Bleaching induced by the loss of the symbiotic relationship between algae and coral is mainly attributed to climate change. Marine protected areas (MPAs) can effectively prevent local disturbances but are less likely to conserve the coral reefs from global events (...) like climate change. Other conservation and restoration methods can be useful to protect and replenish the coral population temporarily, but whether they are feasible as sustainable conservation strategies is still equivocal. Coral reef mass mortality is not an exceptional occurrence but is linked to various instances of ecological loss, serving as an S.O.S. signal of severe prolonged climate extremes. (shrink)

Coral bleaching has attracted considerable study, yet one central question remains unanswered: given that corals and their Symbiodinium symbionts have co‐evolved for millions of years, why does this clearly maladaptive process occur? Bleaching may result from evolutionary conflict between the host corals and their symbionts. Selection at the level of the individual symbiont favors using the products of photosynthesis for selfish replication, while selection at the higher level favors using these products for growth of the entire host/symbiont (...) community. To hold the selfish lower‐level units in check, mechanisms of conflict mediation must evolve. Fundamental features of photosynthesis have been co‐opted into conflict mediation so that symbionts that fail to export these products produce high levels of reactive oxygen species and undergo programmed cell death. These mechanisms function very well under most environmental conditions, but under conditions particularly detrimental to photosynthesis, it is these mechanisms of conflict mediation that trigger bleaching.

Coral bleaching has impacted reefs worldwide and the predictions of near‐annual bleaching from over two decades ago have now been realized. While technology currently provides the means to predict large‐scale bleaching, predicting reef‐scale and within‐reef patterns in real‐time for all reef users is limited. In 2020, heat stress across the Great Barrier Reef underpinned the region's third bleaching event in 5 years. Here we review the heterogeneous emergence of bleaching across Heron Island reef habitats (...) and discuss the oceanographic drivers that underpinned variable bleaching emergence. We do so as a case study to highlight how reef end‐user groups who engage with coral reefs in different ways require targeted guidance for how, and when, to alter their use of coral reefs in response to bleaching events. Our case study of coral bleaching emergence demonstrates how within‐reef scale nowcasting of coral bleaching could aid the development of accessible and equitable bleaching response strategies on coral reefs.

If we are to ensure the persistence of species in an increasingly warm world, of interest is the identification of drivers that affect the ability of an organism to resist thermal stress. Underpinning any organism's capacity for resistance is a complex interplay between biological and physical factors occurring over multiple scales. Tropical coral reefs are a unique system, in that their function is dependent upon the maintenance of a coral–algal symbiosis that is directly disrupted by increases in water (...) temperature. A number of physical factors have been identified as affecting the biological responses of the coral organism under broadscale thermal anomalies. One such factor is water flow, which is capable of modulating both organismal metabolic functioning and thermal environments. Understanding the physiological and hydrodynamic drivers of organism response to thermal stress improves predictive capabilities and informs targeted management responses, thereby increasing the resilience of reefs into the future.

The consideration of ‘mutual benefits’ and partner cooperation have long been the accepted standpoint from which to draw inference about the onset, maintenance and breakdown of the coral‐algae endosymbiosis. In this paper, I review recent research into the climate‐induced breakdown of this important symbiosis (namely ‘coral bleaching’) that challenges the validity of this long‐standing belief. Indeed, I introduce a more parsimonious explanation, in which the coral host exerts a ‘controlled parasitism’ over its algal symbionts that is (...) akin to an enforced domestication arrangement. Far from being pathogenic, a range of well‐established cellular processes are reviewed that support the role of the coral host as an active ‘farmer’ of the energy‐rich photoassimilates from its captive symbionts. Importantly, this new paradigm reposes the deleterious bleaching response in terms of an envelope of environmental conditions in which the exploitative and captive measures of the coral host are severely restricted. The ramification of this new paradigm for developing management strategies that may assist the evolution of bleaching resistance in corals is discussed. (shrink)

In this paper I challenge the notion that a healthy and resilient coral is (in all cases) a fast‐growing coral, and by inference, that a reef characterised by a fast trajectory toward high coral cover is necessarily a healthy and resilient reef. Instead, I explain how emerging evidence links fast skeletal extension rates with elevated coral‐algae (symbiotic) respiration rates, most‐often mediated by nutrient‐enlarged symbiont populations and/or rising sea temperatures. Elevated respiration rates can act to reduce the (...) autotrophic capacity (photosynthesis:respiration ratio) of the symbiosis. This restricts the capacity of the coral host to build and maintain sufficient energy reserves (e.g. lipids) needed to sustain essential homeostatic functions, including sexual reproduction and biophysical stress resistance. Moreover, it explains the somewhat paradoxical scenario, whereby at the ecological instant before the reef‐building capacity of the symbiosis is lost, a reef can look visually at its best and be accreting CaCO3 at its maximum.

The dinoflagellates, a diverse sister group of the malaria parasites, are the major agents causing harmful algal blooms and are also the symbiotic algae of corals. Dinoflagellate nuclei differ significantly from other eukaryotic nuclei by having extranuclear spindles, no nucleosomes and enormous genomes in liquid crystal states. These cytological characteristics were related to the acquisition of prokaryotic genes during evolution (hence Mesokaryotes), which may also account for the biochemical diversity and the relatively slow growth rates of dinoflagellates. The fact that (...) the proliferation of many dinoflagellates is sensitive to turbulence may be due to the physiological requirements of the genome's liquid crystal states. Mechanical stress and anti‐microtubule drugs induce cell cycle arrest mainly in G1, implicating a role for the permanent cortical microtubular cytoskeleton in mechanotransduction. The cell cycles of photosynthetic dinoflagellates are also gated by the circadian rhythm, with cell division occurring mainly at the end of the dark phase. Cell growth and the biosynthesis of many toxins occur during the light phase, corresponding to G1 in the cell cycle. The dinoflagellates also embody several options for coupling cell cycle progression to cell growth, enabling them to make the best use of available resources and possibly preparing them for a symbiotic existence.

Companies are beginning to recognise the concept of Corporate Social Responsibility as presenting a new business model and an opportunity for building innovative forms of competitive advantage. Boards are instrumental in shaping and overseeing such strategies and active engagement around what it means to be a responsible and responsive enterprise can strengthen the Board's potential as a strategic influence on long-term value creation. Yet many companies align with Friedman's contention that adopting and practising CSR is a distraction from their core (...) obligation, which is to act in their shareholders' best interests. Based on directors' perceptions, the paper examines responses by Boards to socially related aspects of their governance role and reports on their external orientation and receptiveness toward wider social obligations. The findings suggest that these Boards hold a narrow view of their fiduciary duty, which is closer to the shareholder model than the stakeholder approach to corporate governance. (shrink)

Start-up organisations are small companies that experience a high level of growth and considerable risk to their very survival until they evolve into stable, established companies. This situation presents a particular set of challenges in terms of corporate governance, yet research on the governance of start-ups is limited. This research paper examines and comments on the governance of start-up organisations in New Zealand. The study replicates and extends previous New Zealand-based research of boards of established companies. From the data gathered (...) from the two surveys, conclusions can be drawn as to the role and focus of boards in start-ups versus established companies. The results are consistent with a model of active ownership which identifies key differences from established companies that could improve the governance of start-ups. The results also highlight the dependence of what might constitute effective corporate governance for a start-up on the strategic context of the company and its life cycle stage. (shrink)

A lo largo de los siglos XVII y XVIII se desarrollaron sucesivas reformulaciones del contrato social a partir de la propuesta hobbesiana, categorizadas hoy en día bajo el rótulo de contractualismo clásico. Dentro de tales propuestas se sostiene que fue con Rousseau con quien el contrato social alcanzó su momento de plena madurez, racionalizándose y profundizándose sus consecuencias democráticas. Así pues, el contrato social es —dentro de la filosofía política— el elemento más significativo para sustentar la teoría del Estado moderno. (...) Sin embargo, una importante consecuencia de dicha teorización es el hecho de que el naciente Estado moderno detente para sí el monopolio de la violencia. Así pues, es posible que un obscuro trasfondo de violencia se oculte tras la formulación contractualista. El artículo que sigue pretende desarrollar un análisis de la teoría del contrato social, particularmente en la formulación de Rousseau, a partir de la teoría mimética de René Girard, con el objetivo de encontrar en su obra más representativa El contrato social, rastros de la violencia mimética y el mecanismo de chivo expiatorio planteados en la teoría girardiana.

Global concerns over environmental and social issues in agrifood value chains have increased and are reflected in a number of voluntary sustainability standards and regulatory initiatives. However, these initiatives are often based on poor knowledge of production realities, creating a disconnect between producing and consuming countries. Through narrative analysis, this paper reveals asymmetries in the responsibilities of the various actors participating in Ecuadorian banana value chains, providing clear problem- and solution-framings. Despite the broad range of actors interviewed, our analysis reveals (...) convergence in two main narratives that reflect asymmetries amongst local actors in terms of their ability to participate, ability to maintain participation, and adaptation strategies in view of changing external factors. One narrative relates to sustainability adaptations, the cost of which is not shared among all value chain actors. This is combined with a downward trend in the price of bananas and the lack of a differentiated price to account for losses and costs arising from increasing sustainability standards. Another narrative reflects a value chain structure that threatens small-farm survival. It highlights the urgency of protecting small-farm activity by enforcing national regulation and developing new market segments/models that understand small-scale producer reality. Study results show that the multitude of standards is not seen as beneficial and that downstream actors rather wish for common minimum standards to reduce business costs. Compatibility between standards and local realities should be a priority for global sustainability standards adoption. Building on the problems and solution-framings of local value chain links, we give voice to local actors, and link their perceptions to existing literature and discursive politics while contributing to social transparency and addressing the democratic deficit in agrifood value chains.

Animals use their chemosensory systems to detect and discriminate among chemical cues in the environment. Remarkable progress has recently been made in our knowledge of the molecular and cellular basis of chemosensory perception in insects, based largely on studies in Drosophila. This progress has been possible due to the identification of gene families for olfactory and gustatory receptors, the use of electro‐physiological recording techniques on sensory neurons, the multitude of genetic manipulations that are available in this species, and insights from (...) several insect model systems. Recent studies show that the superfamily of chemoreceptor proteins represent the essential elements in chemosensory coding, endowing chemosensory neurons with their abilities to respond to specific sets of odorants, tastants or pheromones. Investigating how insects detect chemicals in their environment can show us how receptor protein structures relate to ligand binding, how nervous systems process complex information, and how chemosensory systems and genes evolve.

This paper explores the ways in which neoliberal schooling is threatening education. We define education as the development of cognitive and imaginative capacities for understanding of and critical engagement with social reality. Education opens horizons of possibility for collective and individual life-experience and activity by exposing the one-sidedness and contradictions of ruling-value systems. Schooling, by contrast, subordinates thought and imagination to the reproduction of the ruling money-value system, narrowing horizons of possibility for collective and individual life to service to the (...) prevailing structure of power. Our paper draws on our overlapping experiences as educators, one in the university system, the other in the adult education system. In both systems, students’ life-requirement for education is subordinated to the capitalist need for compliant wage-labourers and consumers. In opposition to this instrumentalization we will present an interpretation of “real world education” as a unique form of collective work through which teachers and students construct alternatives that can serve as the guiding ideas for new projects for social and political transformation.

Tissues are shaped and patterned by mechanical and chemical processes. A key mechanical process is the positioning of the mitotic spindle, which determines the size and location of the daughter cells within the tissue. Recent force and position-fluctuation measurements indicate that pushing forces, mediated by the polymerization of astral microtubules against­ the cell cortex, maintain the mitotic spindle at the cell center in Caenorhabditis elegans embryos. The magnitude of the centering forces suggests that the physical limit on the accuracy and (...) precision of this centering mechanism is determined by the number of pushing microtubules rather than by thermally driven fluctuations. In cells that divide asymmetrically, anti-centering, pulling forces generated by cortically located dyneins, in conjunction with microtubule depolymerization, oppose the pushing forces to drive spindle displacements away from the center. Thus, a balance of centering pushing forces and anti-centering pulling forces localize the mitotic spindles within dividing C. elegans cells. We discuss microtubule-based mechanisms of the mitotic spindle positioning, a key mechanical process that shapes and patterns tissues. The magnitude of the centering forces indicates that the physical limit on the accuracy and precision of centering is set by the number of contributing microtubules rather than by thermally driven fluctuations.

Resumen La literatura universal, se encuentra poblada de arquetípicos que comparten una condición de desamparo y marginalidad, siendo la literatura realista de la segunda mitad del siglo XIX la que constata y da cuenta de su condición. En un mismo sentido, también la Biblia presenta un sinnúmero de personajes similares, marcando un punto de inflexión al llamarlo bienaventurados. Así pues, el presente estudio bíblico-literario, se centra en el arquetipo de la “viuda pobre”, sosteniendo dicha ficción literaria es una clave interpretativa (...) de la realidad, a la luz de la teoría literaria de la Estética de la Recepción. El articulo estudia la “viuda pobre” como un imaginario cultural y estableciendo la recepción de dicho imaginario en los cuentos “El Chiflón del diablo” y “El pago” del escritor chileno Baldomero Lillo, demostrando cómo el dialogo entre cultura y Biblia representa un aporte a la comprensión de determinadas ficciones literarias como categorías antropológicas.Universal literature is crowded by archetypical characters who share abandonment and marginalization conditions, being second half 19,h century realistic literature that confirms and exposes those conditions. In that sense, The Holy Bible presents a number of those characters. Resides, it highlights a turning point, hence, The Beatitudes point out: “Blessed are the poor in spirit, for theirs is the kingdom of heaven”. Thus, the following biblical-literary study, centered in the “Poor widow” archetype, aims to the establishment of literary fiction as interpretative key of reality, under Wolfgang Iser Aesthetics Reception's theory as its methodology. The objective aims to postulate “Poor Widow” as a Cultural imaginary, and finally to establish the reception of that imaginary within the stories “El Chiflón del Diablo” and “El Pago” by the chilean writer Baldomero Lillo, demonstrating that the dialog between culture and The Holy Bible represents a contribution to some literary fiction s as anthropological categories.

Resumen En este trabajo se realiza un análisis exploratorio sobre lo que se ha venido concibiendo como un nuevo campo del saber científico desde hace algunas décadas, nos referimos a la neuroteología. También se pretende entender hasta qué punto la filosofía naturalista contemporánea puede estar vinculada con la neuroteología -sobre todo cuando el naturalismo implica, en la mayoría de los casos, un reduccionismo que conduce al materialismo-, teniendo en conside ración que en las distintas áreas neurocientíficas tiene lugar un fisicalismo, (...) esto es, una reducción de las propiedades o procesos cognitivos a meros procesos cerebrales e interacciones neuronales, que, gracias a la tecnología, hoy pueden ser visualizados por distintos instrumentos y técnicas.In this work an exploratory analysis is carried out on what has been conceived as a new field of scientific knowledge for some decades, we refer to neurotheology. It is also intended to under- stand to what extent contemporary naturalistic philosophy can be linked to neurotheology - especially when naturalism implies, in most cases, a reductionism that leads to materialism -, taking into account that in the different neuroscientific areas it has instead a physicalism, that is, a reduction of cognitive properties or processes to mere brain processes and neural interactions, which, thanks to technology, can now be visualized by different instruments and techniques.

Addiction is increasingly described as a “chronic and relapsing brain disease”. The potential impact of the brain disease model on the treatment of addiction or addicted individuals’ treatment behaviour remains uncertain. We conducted a qualitative study to examine: (i) the extent to which leading Australian addiction neuroscientists and clinicians accept the brain disease view of addiction; and (ii) their views on the likely impacts of this view on addicted individuals’ beliefs and behaviour. Thirty-one Australian addiction neuroscientists and clinicians (10 females (...) and 21 males; 16 with clinical experience and 15 with no clinical experience) took part in 1 h semi-structured interviews. Most addiction neuroscientists and clinicians did not uncritically support the use of brain disease model of addiction. Most were cautious about the potential for adverse impacts on individuals’ recovery and motivation to enter treatment. While some recognised the possibility that the brain disease model of addiction may provide a rationale for addicted persons to seek treatment and motivate behaviour change, Australian addiction neuroscientist and clinicians do not assume that messages about “diseased brains” will always lead to increased treatment-seeking and reduced drug use. Research is needed on how neuroscience research could be used in ways that optimise positive outcomes for addicted persons. (shrink)

Nosotros coincidimos hace algunos años en un congreso académico internacional en el que se discutían propuestas investigativas y prácticas pedagógicas enmarcadas en perspectivas alejadas de enfoques cognitivistas y más próximas a dimensiones sociales, políticas y culturales. Allí, (...) compartimos nuestros trabajos académicos y años más tarde nos reencontramos en el II Encuentro de la Red de Educadores Matemáticos Críticos, notando que, si bien nuestros intereses no habían cambiado, estábamos interesados en reconocer la voz del sujeto al relatar sus experiencias investigativas situadas desde enfoques sociales, políticos y culturales de la educación matemática. Para ello usamos las narrativas orales y escritas para estudiar y reflexionar sobre nuestras propias experiencias como docentes de matemáticas. Para lograrlo, teóricamente nos fundamentamos en las ideas del enfoque social, político y cultural, especialmente, en la Educación Matemática Crítica y la Etnomatemática, caracterizando tanto la idea de sujeto político como de contexto sociopolítico. Con relación a la metodología, retomamos la idea de experiencia de Jorge Larrosa y las características de la investigación biográfico-narrativa, usando particularmente los escritos autobiográficos producidos por los autores del presente documento. Buscamos dar vida a la voz del sujeto al narrar sus propias experiencias como docentes e investigadores de carne y hueso que intentan privilegiar en el aula de clase espacios de discusión sobre asuntos sociales, políticos y culturales que se inscriben en los contextos cotidianos de las escuelas colombianas. Además, reconocemos la importancia de usar las matemáticas como herramienta que nos permite leer, interpretar y transformar el mundo y las condiciones de nuestra sociedad actual, reconociéndonos como sujetos políticos agentes de cambio.

Australia does not allow adult smokers to buy or use electronic nicotine delivery systems that contain nicotine without a prescription. This paper critically evaluates the empirical and ethical justifications provided for the policy by Federal and State governments, public health advocates and health organisations. These are: that ENDS should only be approved as products for smoking cessation when there is evidence from randomised controlled trials that they are effective; that as a matter of precaution we should not allow the sale (...) of ENDS to smokers as consumer products because we do not know what their long-term effects will be; and that allowing ENDS to be sold as consumer goods will enable the tobacco industry to market ENDS to young people which will also lead to an increase in youth smoking. We show that the arguments and evidence offered in support of all these claims is very weak. We also argue that even if the evidence were stronger, it would not justify denying adult smokers the right to use ENDS either to quit smoking or as a long-term alternative to smoking cigarettes. We outline ENDS policies that would more ethically address the public health concerns that motivated the current policy by allowing adult smokers to access ENDS for smoking cessation or tobacco harm reduction under tight regulations that discourage commercial promotion and adolescent use.
