ReviewPublication Accessing elite nurses for research: Reflections on the theoretical and practical issues of telephone interviewingThis paper addresses two very interesting and relevant issues in terms of nursing and nursing research, one because of its relationship to matters of elitism, nursing empowerment, oppression and the researchers' responsibilities to gather data from all parts of the professional nursing spectrum. The other because it offers a practical and well-considered insight into an under utilised and yet simple approach to gathering research data (even for nonelite groups).2331 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Book Review - The Little Book of Plagiarism, by Richard A. PosnerThe Little Book of Plagiarism is very small indeed, but, as the flysheet puts it, this is the work of “one of the top twenty legal thinkers in America (Legal Affairs), a distinguished jurist renowned for his adventuresome intellect and daring iconoclasm.” Richard Posner is, if nothing else, profuse. He is also a highly respected intellectual, known for being frank, and even when contentious, he typically has some useful perspective to contribute to any debate. Given the source, my expectations were high for this book, but the content is a little disappointing: it reads like a narration of the dreamy musings that one may have on a long plane trip, albeit by a thoughtful person contemplating plagiarism. In short, The Little Book makes many points that are key to a study on plagiarism, although they are not structured into any cohesive argument. Here, I shall first indicate the coverage of the book and follow with a short discussion of some of the points raised.2213 1 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Boundaries in the Medieval and Wider World: Essays in Honour of Paul Freedman ed. by Thomas W. Barton etal. (review)(Australian and New Zealand Association for Medieval and Early Modern Studies, 2019-04)Paul Freedman's Festschrift reflects his approach to studying history, which encompasses the aim of making history alive and using the past to shed light on the present as well as the future. The fifteen chapters that form this volume do not follow predictable or well-worn paths and they do not duplicate existing scholarship. Instead, the reader encounters a bevy of topics all presented with panache and most of them tantalizing the reader with the lure of shifting boundaries, unlikely applications, and penetrating insights. Between the covers of this Festschrift one learns about a variety of topics such as high divorce rates in medieval Jewish communities and the limitations of notarial Latin (Sarah Ifft Decker), and concepts of slavery within convents (Michelle Herder). We also learn that powerful scary women could be every bit as bad as their male counterparts (Jeffrey A. Bowman). In Fontevraud Abbey, a foundation which included both male and female religious, women assumed unconventional and fascinating governance, and unsurprisingly were also considered vessels filled with poison (Annalena Müller).

Publication Open AccessReviewBrain Lateralization and Cognitive CapacityOne way to increase cognitive capacity is to avoid duplication of functions on the left and right sides of the brain. There is a convincing body of evidence showing that such asymmetry, or lateralization, occurs in a wide range of both vertebrate and invertebrate species. Each hemisphere of the brain can attend to different types of stimuli or to different aspects of the same stimulus and each hemisphere analyses information using different neural processes. A brain can engage in more than one task at the same time, as in monitoring for predators (right hemisphere) while searching for food (left hemisphere). Increased cognitive capacity is achieved if individuals are lateralized in one direction or the other. The advantages and disadvantages of individual lateralization are discussed. This paper argues that directional, or population-level, lateralization, which occurs when most individuals in a species have the same direction of lateralization, provides no additional increase in cognitive capacity compared to individual lateralization although directional lateralization is advantageous in social interactions. Strength of lateralization is considered, including the disadvantage of being very strongly lateralized. The role of brain commissures is also discussed with consideration of cognitive capacity.1195 177 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Cancer and life-history traits: lessons from host-parasite interactions(Cambridge University Press, 2016) ;Ujvari, Beata; ;Renaud, Francois ;Vittecoq, Marion ;Tissot, Tazzio ;Roche, Benjamin ;Poulin, Robert ;Thomas, Frederic ;Biro, Peter A ;Arnal, Audrey ;Tasiemski, Aurelie ;Massol, Francois ;Salzet, Michel ;Mery, Frederic ;Boidin-Wichlacz, CelineMisse, DorotheeDespite important differences between infectious diseases and cancers, tumour development (neoplasia) can nonetheless be closely compared to infectious disease because of the similarity of their effects on the body. On this basis, we predict that many of the life-history (LH) responses observed in the context of host-parasite interactions should also be relevant in the context of cancer. Parasites are thought to affect LH traits of their hosts because of strong selective pressures like direct and indirect mortality effects favouring, for example, early maturation and reproduction. Cancer can similarly also affect LH traits by imposing direct costs and/or indirectly by triggering plastic adjustments and evolutionary responses. Here, we discuss how and why a LH focus is a potentially productive but under-exploited research direction for cancer research, by focusing our attention on similarities between infectious disease and cancer with respect to their effects on LH traits and their evolution. We raise the possibility that LH adjustments can occur in response to cancer via maternal/paternal effects and that these changes can be heritable to (adaptively) modify the LH traits of their offspring. We conclude that LH adjustments can potentially influence the transgenerational persistence of inherited oncogenic mutations in populations.2220 1 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Chemical and physical characteristics of grains related to variability in energy and amino acid availability in poultryGrains such as wheat and barley, combined with legumes and oilseed meals, provide not only the bulk of essential nutrients for commercial poultry production and reproduction, but are also the prime source of anti-nutritive components, which are likely to have significant bearing on how effectively all dietary components are utilised by poultry. Sources of variation in the physical and chemical characteristics of grains used in poultry diets include variety, seasonal effects, and growth sites, crop treatment and grain fumigants, and post-harvest storage conditions and period of storage. The available energy and protein contents of grains fed to poultry, which best represent nutritive value, are extremely wide and in consequence there is an urgent need to develop rapid and objective tests for the assessment of nutritive value prior to including grains in poultry diets. Variation in the available energy and protein content of grains can be attributed to a wide range of anti-nutritive factors such as non-starch polysaccharides (NSP), enzyme activity, tannins, alkyl resorcinols, protease inhibitors, α-amylase inhibitors, phytohaemagglutinins, alkaloids, saponins, and lathyrogens. The relative importance of such factors will also differ according to the type of grain in question. However, NSP seem to be the predominant factor in Australia over the past few years given the volume of published literature on this topic. This argument is strongly supported by the fact that NSP-degrading enzymes are routinely used in monogastric diets with great success throughout the world. Numerous attempts over a long period have failed to provide unequivocal evidence that nutritive value in grains for poultry can be predicted with sufficient accuracy and precision by simple, low-cost physico-chemical measurements used singly or in combination. Nevertheless, it is highly desirable to continue to explore these simple measurements in the expectation that useful statistical relationships with more complex measurements will emerge, or that simple measurements can be used to fine-tune prediction equations based on more powerful techniques such as near infrared spectrophotometry. Finally, the nutritive value of grains for poultry will be determined not only by the chemical and physical properties of grains but also by the way that these interact with the processes of ingestion, digestion, absorption, and metabolism in birds. For this reason it is imperative that plant and animal scientists join forces to improve the nutritive value of plant material as feed for animals for the benefit of grain growers and producers of livestock.2359 - Some of the metrics are blocked by yourconsent settings
Publication Open AccessReviewChild Abuse and Dental Practice: Finding the NexusMany reports indicate that children are abused everyday worldwide. They are abused in many different ways. Literature suggests that the numbers of reported abuses against children are a mere tip of an iceberg accordingly, there are many unreported cases - some are hidden or covered. Thus, child abuse becomes a social problem. Many seem to ignore child abuses, others of course will justify. Admittedly there are a few who will hide such abuses under a carpet or give a blind eye. In some societies child abuse has become a part of an accepted cultural practice- for example corporal punishments or female genital mutilations. Fortunately, there are some of us in the society who will voice against abuse of children. The social responses to child abuse are reflected in clinical sets up in similar ways. This means that some clinicians will ignore abuses while others may not care. The problem becomes aggravated in clinical scenarios especially when the clinician is not trained in identifying an imminent child abuse. In this context, this paper seeks to find a connection between clinical dental practice and child abuse. In short, I will argue and demonstrate in this paper that the presentations of cases of child abuse are not uncommon to the dental clinician, but that they are often times presented with alternate histories so that they can be easily missed by the clinician, if not looked through forensic lenses.

ReviewPublication A conceptual framework for ecological responses to groundwater regime alteration (FERGRA)Globally, the provision of groundwater‐supported ecosystem services is threatened by climate change, water extraction, and other activities that alter groundwater regimes (defined as temporal dynamics in groundwater pressures, storage, and levels). Research on how altered groundwater regimes affect the ecology and ecosystem services of diverse groundwater‐dependent ecosystems (GDEs) is currently fragmented with little integration across different GDEs, hampering our ability to understand and manage ecological responses to anthropogenic changes to groundwater regimes. To address this, we present a framework for assessing ecological responses to groundwater regime alteration (FERGRA). FERGRA is a logical approach to investigating how alterations to groundwater regimes change the timing, variability, duration, frequency, and magnitude of groundwater connections to different GDEs, in turn affecting their ecological processes and ecosystem service provision. Using FERGRA, multiple GDEs can be assessed concurrently, optimizing their integrated management. Unifying the concepts of ecological responses to altered groundwater regimes and groundwater connections of different GDEs across the landscape, FERGRA provides a framework for (a) organizing the currently fragmented research on GDEs to better identify commonalities and knowledge gaps, (b) formulating and testing hypotheses for quantifying ecological responses to groundwater regime alteration in GDEs to derive general principles to guide research and management, and (c) facilitating assessments of the trade‐offs between the benefits of groundwater extraction (e.g., to support mining and agriculture) versus conservation of GDEs to protect other ecosystem services.

Publication Open AccessReviewDeconstructing pollinator community effectiveness(Elsevier BV, 2017); ;Aizen, Marcelo A ;Cunningham, Saul A ;Mayfield, Margaret MEffective pollination is a complex, context-dependent phenomenon determined by both species-level and community-level factors. While pollinator communities are constituted by interacting organisms in a shared environment, these factors are often simplified or overlooked when quantifying species-level pollinator effectiveness alone. Here, we review the recent literature on pollinator effectiveness to identify the pros and cons of existing methods and outline three important areas for future research: plant-pollinator interactions, heterospecific pollen transfer and variation in pollination outcomes. We conclude that pollinator community effectiveness needs to be acknowledged as a key property of pollination effectiveness in order to fully account for the suite of plant, pollinator and environmental factors known to influence different stages of successful pollination.2559 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Developing workable research methods: Lessons from a pilot study with vulnerable participants and complex assessmentsThis paper highlights the value of a pilot study when planning or designing a research project. Pilot studies allow researchers to test the feasibility and logistics of larger studies. They offer an opportunity for the researcher to test the research question and its applicability to the target population, to assess the relevance and suitability of the tests, tools or methods used in the research and to gather preliminary data that can be used to assess the validity and appropriateness of the analysis approach being planned. A well-designed pilot study can also offer an opportunity for researchers to improve the quality and efficiency of the research under consideration and even reveal gaps or deficiencies in the proposed research. All of this allows researchers to gain insights into their planned research without wasting time or incurring the costs associated with planning or running a larger study.2335 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Do Sideline Tests of Vestibular and Oculomotor Function Accurately Diagnose Sports-Related Concussion in Adults? A Systematic Review and Meta-analysis(Sage Publications, Inc, 2021) ;Harris, Sarah A ;Dempsey, Alasdair R ;Mackie, Katherine; ;Hecimovich, MarkMurphy, Myles CBackground: Sports-related concussion (SRC) assessment tools are primarily based on subjective assessments of somatic, cognitive, and psychosocial/emotional symptoms. SRC symptoms remain underreported, and objective measures of SRC impairments would be valuable to assist diagnosis. Measurable impairments to vestibular and oculomotor processing have been shown to occur after SRC and may provide valid objective assessments.
Purpose: Determine the diagnostic accuracy of sideline tests of vestibular and oculomotor dysfunction to identify SRC in adults.
Study Design: Systematic review; Level of evidence, 4.
Methods: Electronic databases and gray literature were searched from inception until February 12, 2020. Physically active individuals (> 16 years of age) who participated in sports were included. The reference standard for SRC was a combination of clinical signs and symptoms (eg, the Sport Concussion Assessment Tool [SCAT]), and index tests included any oculomotor assessment tool. The QUADAS tool was used to assess risk of bias, with the credibility of the evidence being rated according to GRADE.
Results: A total of 8 studies were included in this review. All included studies used the King-Devick test, with no other measures being identified. Meta-analysis was performed on 4 studies with a summary sensitivity and specificity of 0.77 and 0.82, respectively. The overall credibility of the evidence was rated as very low.
Conclusion: Caution must be taken when interpreting these results given the very low credibility of the evidence, and the true summary sensitivity and specificity may substantially differ from the values calculated within this systematic review. Therefore, we recommend that clinicians using the King-Devick test to diagnose SRC in adults do so in conjunction with other tools such as the SCAT.

Publication Open AccessReviewEffects of Weight Cutting on Exercise Performance in Combat Athletes: A Meta-AnalysisWeight cutting in combat sports is a prevalent practice whereby athletes voluntarily dehydrate themselves via various methods to induce rapid weight loss (RWL) to qualify for a lower weight category than that of their usual training body weight. The intention behind this practice is to regain the lost body mass and compete at a heavier mass than permitted by the designated weight category. The purpose of this study was to quantitatively synthesize the available evidence examining the effects of weight cutting on exercise performance in combat-sport athletes. Following a systematic search of the literature, meta-analyses were performed to compare maximal strength, maximal power, anaerobic capacity, and/or repeated high-intensity-effort performance before rapid weight loss (pre-RWL), immediately following RWL (post-RWL), and 3 to 36 hours after RWL following recovery and rapid weight gain (post-RWG). Overall, exercise performance was unchanged between pre-RWL and post-RWG (g = 0.22; 95% CI, −0.18 to 0.62). Between pre-RWL and post-RWL analyses revealed small reductions in maximal strength and repeated high-intensity-effort performance (g = −0.29; 95% CI, −0.54 to −0.03 and g = −0.37; 95% CI, −0.59 to −0.16, respectively; both P ≤ .03). Qualitative analysis indicates that maximal strength and power remained comparable between post-RWL and post-RWG. These data suggest that weight cutting in combat-sport athletes does not alter short-duration, repeated high-intensity-effort performance; however, there is evidence to suggest that select exercise performance outcomes may decline as a product of RWL. It remains unclear whether these are restored by RWG.

Publication Open AccessReviewEnvisioning Tesol Through A Translanguaging Lens: Global PerspectivesIf you are ready to challenge your views and practices about how language is used in English language classrooms, reading this book will provide you with plenty of thought-provoking material to assist you in your endeavours. With each chapter, the authors confront established views of language usage and teaching practice in TESOL. You, like I, may have heard classroom practitioners, managers and academics express strong views about students' first language (L1) usage in class. This volume highlights the need for some commonly held views about second language acquisition (SLA) to be redefined, if translanguaging is to become more widely understood and embedded in TESOL teacher education, research and classroom practices.

ReviewPublication A function for the bicameral mindWhy do the left and right sides of the brain have different functions? Having a lateralized brain, in which each hemisphere processes sensory inputs differently and carries out different functions, is common in vertebrates, and it has now been reported for invertebrates too. Experiments with several animal species have shown that having a lateralized brain can enhance the capacity to perform two tasks at the same time. Thus, the different specializations of the left and right sides of the brain seem to increase brain efficiency. Other advantages may involve control of action that, in Bilateria, may be confounded by separate and independent sensory processing and motor outputs on the left and right sides. Also, the opportunity for increased perceptual training associated with preferential use of only one sensory or motoric organ may result in a time advantage for the dominant side. Although brain efficiency of individuals can be achieved without the need for alignment of lateralization in the population, lateral biases (such as preferences in the use of a laterally-placed eye) usually occur at the population level, with most individuals showing a similar direction of bias. Why is this the case? Not only humans, but also most non-human animals, show a similar pattern of population bias (i.e., directional asymmetry). For instance, in several vertebrate species (from fish to mammals) most individuals react faster when a predator approaches from their left side, although some individuals (a minority usually ranging from 10 to 35%) escape faster from predators arriving from their right side. Invoking individual efficiency (lateralization may increase fitness), evolutionary chance or simply genetic inheritance cannot explain this widespread pattern. Using mathematical theory of games, it has been argued that the population structure of lateralization (with either antisymmetry or directional asymmetry) may result from the type of interactions asymmetric organisms face with each other.1969 4 - Some of the metrics are blocked by yourconsent settings

ReviewPublication Inquisition and its Organization in Italy 1250–1350 by Jill Moore (review)(Australian and New Zealand Association for Medieval and Early Modern Studies, 2020-12)Henry Charles Lea is the standard by which all studies of the inquisition are measured. His epochal work was brilliant, immense, and frequently definitive. In an important essay, Richard Kieckhefer argued there was no such thing as 'the Medieval Inquisition'. While acknowledging their acumen and contributions, Jill Moore challenges both scholars. Her revisionist monograph is a significant achievement. Where Lea tackled the subject on a European scale and Kieckhefer sought to correct a misapprehension, Moore limited herself to a century of medieval history in Italy. In this way she succeeds in delving deeply into archival materials where she examines the mechanics of inquisitorial activities. Going beyond most historians of heresy, Moore interrogates the development of the Italian inquisition by investigating the lives of individuals who made inquisition possible, Building on the provisions of the thirteenth-century papal bull Ad extirpanda, Moore explores the relationship between inquisitors, local bishops, and immediate civil authorities. She argues the traditional image of the feared and autonomous medieval inquisitor requires nuance. The supporting cast of notaries, messengers, spies, familia, vicars, informers, companions, bankers, jailers, and 'those who served the sacred office' in a variety of ways, enabled the inquisitor to function effectively.

Publication Open AccessReviewIntegrating ecosystem services into conservation strategies for freshwater and marine habitats: a review- Over the last two decades, there has been increasing public and political recognition of society's dependency upon natural habitat complexity and ecological processes to sustain provision of crucial ecosystem services, ranging from supplying potable water through to climate regulation. How has the ecosystem-services perspective been integrated into strategies for aquatic habitat conservation?
- Literature on conservation of diverse freshwater and marine habitats was reviewed to assess the extent to which past and current strategies specifically targeted ecosystem services, and considered ecosystem functions, potential trade-offs and social issues when formulating protection measures for conserving aquatic habitats.
- Surprisingly few published examples exist where comprehensive assessment of ecosystem services supported development of conservation plans. Seldom were aquatic habitat conservation objectives framed in terms of balancing trade-offs, assessing social values and evaluating suites of ecosystem services under different strategies. Time frames for achieving these objectives were also rarely specified. There was no evidence for fundamental differences between marine and freshwater habitats with respect to their ecosystem services that should be considered when setting targets for their conservation.
- When an ecosystem-service perspective is used for setting objectives in aquatic habitat conservation, the following actions are recommended: (1) explicitly listing and evaluating full suites of ecosystem services to be conserved; (2) identifying current and future potential trade-offs arising from conservation; (3) specifying time frames within which particular strategies might protect or enhance desired services; and (4) predicting how different proposed strategies might affect each ecosystem function, service flow and public benefit.
- This approach will help ensure that less-apparent ecosystem services (e.g. regulating, supporting) and their associated ecosystem functions receive adequate recognition and protection in aquatic conservation of freshwater and marine habitats. However, conservation objectives should not focus solely on protecting or enhancing ecosystem services but complement current strategies targeting biodiversity and other conservation goals.

ReviewPublication Island Home [Book Review]Tim Winton's Island Home (2015) carries the sub-title 'A landscape memoir', and it will not surprise readers of Winton's fiction that he handles the elastic form of the memoir with novelistic flair. He eschews conventional chronology, arranging a looser narrative mosaic befitting the mode of peripheral perception he celebrates: the power of 'vision beyond mere glimpsing', as he puts it in his earlier essay bearing the same sub-title,'Strange passion: a landscape memoir'(1999).2505 - Some of the metrics are blocked by yourconsent settings
Publication Open AccessReviewLanguage Across the Curriculum & CLIL in English as an Additional Language (EAL) ContextsOver the last two decades, Content and Language Integrated Learning (CLIL) has emerged as a growing interest in research in TESOL. As a teaching approach focusing on both language and content, the term CLIL was firstly adopted in 1994 in Europe and practiced in a range of contexts (Coyle, Hood, & Marsh, 2010). As a part of the growing body in CLIL literature, Angel Lin's Language Across the Curriculum & CLIL in English as an Additional Language (EAL) Contexts contributes to the recent development of language and content integration with concrete examples while explicitly addressing challenges experienced in CLIL and LAC (Language Across the Curriculum) in EAL. Due to its comprehensive account of how LAC and CLIL can be employed in EAL contexts with practical examples, this book is particularly useful for teachers and educators who are in search of concrete pedagogical approaches to incorporate CLIL and LAC in class. There are two key objectives for this book" it firstly establishes a solid theoretical foundation by critically and systematically reviewing a range of theories and literature regarding CLIL and LAC. The second half of the book intends to respond to everyday challenges and needs expressed by EAL teachers with pedagogical suggestions and examples to facilitate collaboration across language and content.

ReviewPublication Managing gut health without reliance on antimicrobials in poultryIt is well established that antimicrobials in animal feed enhance feed efficiency, promote animal growth and improve the quality of animal products. However, resistance development in bacterial populations, and hence consumer demand for products free of antimicrobial residues, has prompted efforts to develop alternatives that can replace antimicrobials without causing loss of productivity or product quality. One of the key barriers to complete withdrawal from antimicrobial use is microbial infection, for example, necrotic enteritis. There is much interest in using in-feed nutraceuticals such as prebiotics, probiotics, organic acids and plant extracts as alternatives to antimicrobials to create a healthy gastrointestinal environment and to prevent and treat enteric infections. Enzymes are generally used to alleviate anti-nutritional factors in feed, but there is growing awareness of their beneficial effects on the gastrointestinal environment, and consequently on gut health. An example of this is production of prebiotic xylo-oligosaccharides when xylanase is added to feed. This review discusses developments in alternatives to antimicrobials that can aid in managing gut health in a post-antimicrobial era, with particular reference to recent nutritional strategies.2312 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Managing the rumen to limit the incidence and severity of nitrite poisoning in nitrate-supplemented ruminantsInclusion of nitrate (NO₃⁻) in ruminant diets is a means of increasing non-protein nitrogen intake while at the same time reducing emissions of enteric methane (CH₄) and, in Australia, gaining carbon credits. Rumen microorganisms contain intracellular enzymes that use hydrogen (H₂) released during fermentation to reduce NO₃⁻ to nitrite (NO₂⁻), and then reduce the resulting NO₂⁻ to ammonia or gaseous intermediates such as nitrous oxide (N₂O) and nitric oxide (NO). This diversion of H2 reduces CH₄ formation in the rumen. If NO₂⁻ accumulates in the rumen, it may inhibit growth of methanogens and other microorganisms and this may further reduce CH4 production, but also lower feed digestibility. If NO₂⁻ is absorbed and enters red blood cells, methaemoglobin is formed and this lowers the oxygen-carrying capacity of the blood. Nitric oxide produced from absorbed NO₂⁻ reduces blood pressure, which, together with the effects of methaemoglobin, can, at times, lead to extreme hypoxia and death. Nitric oxide, which can be formed in the gut as well as in tissues, has a variety of physiological effects, e.g. it reduces primary rumen contractions and slows passage of digesta, potentially limiting feed intake. It is important to find management strategies that minimise the accumulation of NO₂⁻; these include slowing the rate of presentation of NO₃⁻ to rumen microbes or increasing the rate of removal of NO₂⁻, or both. The rate of reduction of NO₃⁻ to NO₂⁻ depends on the level of NO₃⁻ in feed and its ingestion rate, which is related to the animal's feeding behaviour. After NO₃⁻ is ingested, its peak concentration in the rumen depends on its rate of solubilisation. Once in solution, NO₃⁻ is imported by bacteria and protozoa and quickly reduced to NO₂⁻. One management option is to encapsulate the NO₃⁻ supplement to lower its solubility. Acclimating animals to NO₃⁻ is an established management strategy that appears to limit NO₂⁻ accumulation in the rumen by increasing microbial nitrite reductase activity more than nitrate reductase activity; however, it does not guarantee complete protection from NO₂⁻ poisoning. Adding concentrates into nitrate-containing diets also helps reduce the risk of poisoning and inclusion of microbial cultures with enhanced NO₂⁻ - reducing properties is another potential management option. A further possibility is to inhibit NO₂⁻ absorption. Animals differ in their tolerance to NO₃⁻ supplementation, so there may be opportunities for breeding animals more tolerant of dietary NO₃⁻. Our review aims to integrate current knowledge of microbial processes responsible for accumulation of NO₂⁻ in rumen fluid and to identify management options that could minimise the risks of NO₂⁻ poisoning while reducing methane emissions and maintaining or enhancing livestock production.2649 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Nutrient sensing-the key to fungal p53-like transcription factors?The mammalian tumour suppressor protein, p53, plays an important role in cell cycle control, DNA repair and apoptotic cell death. Transcription factors belonging to the “p53-like” superfamily are found exclusively in the Amorphea branch of eukaryotes, which includes animals, fungi and slime molds. Many members of the p53-like superfamily (proteins containing p53, Rel/Dorsal, T-box, STAT, Runt, Ndt80, and the CSL DNA-binding domains) are involved in development. Two families of p53-like proteins (Ndt80 and CSL) are widespread in fungi as well as animals. The Basidiomycetes and the Ascomycetes have undergone reciprocal loss of the Ndt80 and CSL classes of transcription factors, with the CSL class preserved in only one branch of Ascomycetes and the Ndt80 class found in only one branch of Basidiomycetes. Recent studies have greatly expanded the known functions of fungal Ndt80-like proteins and shown that they play important roles in sexual reproduction, cell death, N-acetylglucosamine sensing and catabolism, secondary metabolism, and production of extracellular hydrolases such as proteases, chitinases and cellulases. In the opportunistic pathogen, Candida albicans, Ndt80-like proteins are essential for hyphal growth and virulence and also play a role in antifungal resistance. These recent studies have confirmed that nutrient sensing is a common feature of fungal Ndt80-like proteins and is also found in fungal CSL-like transcription factors, which in animals is the mediator of Notch signalling. Thus, nutrient sensing may represent the ancestral role of the p53-like superfamily.2249 3 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Origins of the Left and Right BrainThe left hemisphere of the human brain controls language, arguably our greatest mental attribute. It also controls the remarkable dexterity of the human right hand. The right hemisphere is dominant in the control of, among other things, our sense of how objects interrelate in space. Forty years ago the broad scientific consensus held that, in addition to language, right-handedness and the specialization of just one side of the brain for processing spatial relations occur in humans alone. Other animals, it was thought, have no hemispheric specializations of any kind.2419 5 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Preparing the air for nursing care: A grounded theory study of first line nurse managersThis paper presents an interesting and well-researched insight into Finish (first line) nurse manager perspectives on nursing leadership. The use of written narratives is unique in this regard and offers a detailed data source for the utilisation of a grounded theory research approach. The four typologies identified, 'the Active Developer, the Passive Thinker, the Impulsive Creator and the Routine Manger' appear to effectively represent the core modalities identified in the study. Reading the study put me in mind of Christian and Norman's (1998) study of clinical leadership in nursing development units as many of the comments by the Finish nurse managers and the conclusions drawn appeared similar. This is perhaps not unusual as this and Christian and Norman's (1998) study approached nurse managers involved in unit/ward level leadership and management positions to gather their research data.2353 - Some of the metrics are blocked by yourconsent settings
ReviewPublication The ‘Reason’ of schooling: historicising curriculum studies, pedagogy, and teacher educationThomas Popkewitz accentuates knowledge about systems of reason that govern educational policy. His research on pedagogy and teacher education includes historical, ethnographic, and comparative studies of national educational reforms in Asia, Europe, Latin America, Southern Africa, and the USA. Two of his books (Paradigms and Ideology in Educational Research and A Political Sociology of Educational Reform) have won awards for their contribution to educational studies. His most recent edited book, The 'Reason' of schooling: Historicizing curriculum studies, pedagogy and teacher education makes a significant contribution to the field of curriculum studies, highlighting the most current global concerns in education. The book makes three significant contributions to the field of practice and policy: discussions around the intersections of various historical trails informing decision-making, the science of education as social discourse to change social conditions, and social epistemology as a strategy to revise critical studies of education. Popkewitz effectively emphasises 'Reason' of schooling as political. He clarifies political as students who attempt to learn, the qualities of the expert teacher, cultural boundaries and its implications for present boundaries in schooling. An in-depth view of the quality of teacher education is highlighted as a current global concern, with Peterson, Olsson, and Krejsler (Chapter 13) claiming that a 'better teacher' and the 'teacher of tomorrow are operating as visions for the future' (p. 205).

Publication Open AccessReviewReview article: Stop, revival(istics), (linguistic) survival(istics): Zuckermann's Revivalistics and Giacon's YaluuThe 19th century saw the rapid cutover of native forests in Australia, Canada, New Zealand and the United States. Due to concerns about deforestation, there arose a nascent conservation movement, which publicised the adverse environmental effects of the cutover, fire, wasteful logging practices, and the importance of sustainable forestry practices. Through an examination of the arguments opposing scientific forestry management and conservation, this article discusses how conservation and economic development were understood and changed in the Anglo-American political economy of the 19th and early 20th centuries. The article argues that these 19th-century debates echo opposition to climate mitigation policy today. It concludes that climate mitigation proponents must reconceptualise the notion of public interest and create a more cohesive narrative regarding the desirability of climate mitigation policies.

Publication Open AccessReviewReview: Key tweaks to the chicken's beak: the versatile use of the beak by avian species and potential approaches for improvements in poultry productionThe avian beak is a multipurpose organ playing a vital role in a variety of functions, including feeding, drinking, playing, grasping objects, mating, nesting, preening and defence against predators and parasites. With regards to poultry production, the beak is the first point of contact between the bird and feed. The beak is also manipulated to prevent unwanted behaviour such as feather pecking, toe pecking and cannibalism in poultry as well as head/ neck injuries to breeder hens during mating. Thus, investigating the beak morphometry of poultry in relation to feeding and other behaviours may lead to novel insights for poultry breeding, management and feeding strategies. Beak morphometry data may be captured by advanced imaging techniques coupled with the use of geometric morphometric techniques. This emerging technology may be utilized to study the effects of beak shape on many critical management issues including heat stress, parasite management, pecking and feeding behaviour. In addition, existing literature identifies several genes related to beak development in chickens and other avian species. Use of morphometric assessments to develop phenotypic data on beak shape and detailed studies on beak-related behaviours in chickens may help in improving management and welfare of commercial poultry.

ReviewPublication The role of the crop in poultry productionThe importance of the crop is often underestimated in poultry production. In addition to storing ingested feed, it also can impact nutrient digestion by digesta softening and the initial activity of feed (endogenous and exogenous) and microbial enzymes. The crop represents the first major defence against poultry pathogens and zoonotic organisms with well established adaptive and innate immune function, and a lactobacilli dominated microbiota capable of reducing the passage of these organisms further along the digestive tract. However, the potential to improve bird productivity and health, as well as affect meat and egg safety, are influenced by the nature of the diet, and in particular feed entry and extended presence in the crop. This is required to promote lactobacilli fermentation, the production of lactic acid and other volatile fatty acids, and the lowering of crop pH. Management practices such as meal feeding and the use of lighting programs with extended dark periods encourage crop utilisation. Further, the use of feed additives such as prebiotics and probiotics may enhance crop function, which in turn contributes to well-being of the entire digestive tract. A healthy and functional crop, along with other segments of digestive tract, has increased importance in an era of reduced antibiotic use in poultry feeds.2440 - Some of the metrics are blocked by yourconsent settings
ReviewPublication Three Editions of Early Seventeenth-Century English Sacred Music(Routledge)The composers Nathaniel Giles (1558–1634), Richard Dering (ca. 1580–1630), and Henry Lawes (1602–1662) lived during a turbulent period of English history from the beginning of the reign of Queen Elizabeth I to the early years of the Restoration of the monarchy. Dering’s name is familiar to many historical musicologists, especially from the earlier research and editions of the late Peter ‘Prof ’ Platt and Philip Brett. Henry Lawes’s brother, William (1602–1645), is better known today for his superb viol consort suites. Giles has remained obscure to all but the most specialized historians of English music. All three men were members of the Chapel Royal during the reigns of one or more English monarchs (Giles, for example, served three monarchs). Their careers briefly overlapped in tantalizing ways to invite further revisions to the history of English sacred music that move beyond current accounts centred on now well-known figures like Thomas Tallis (1505–1585), William Byrd (ca. 1540–1623), and Orlando Gibbons (1583–1625). With the publication of these three new editions, music historians are now better positioned to re-evaluate the development of English sacred music, especially in the context of the Chapel Royal, from standpoints not overshadowed by ‘great’ composers. Yet the compositions contained in all three editions represent a relatively tight cluster of English sacred works from the 1610s to 1630s.

ReviewPublication ‘Units of selection’ is polysemous?This book defends the 'disambiguating project' (DP) with respect to the units of selection, the thesis that the expression 'units of selection' is polysemous, in that it 'refers to at least three non-co-extensional functional concepts: interactor, replicator/ reproducer/reconstitutor, and manifestor of adaptation/type-1 agent' (1). Lewontin (1970) inaugurated the 'recipe' approach to the units of selection issue, the idea that we can identify a small number of conditions, such as variation, differential fitness, and heritability, individually necessary and jointly sufficient for natural selection to take place, and for units of selection to be identified. Later, Hull and Dawkins argued that 'units of selection' could refer to either 'replicators'—entities that pass on their structure in replication—or 'interactors/vehicles'—entities whose interaction with the environment causes replication to be differential. Subsequently a third entity was added: 'manifestors of adaptation/type-1 agents', entities that are cohesive and exhibit accumulated engineering adaptations.
