Hyperplasia and hypertrophy are elements of phenotypic plasticity adjusting organ size and function. Because they are costly, we assume that they are beneficial. In this review, the authors discuss examples of tissue and organ systems that respond with plastic changes to osmotic stress to raise awareness that we do not always have sufficient experimental evidence to conclude that such processes provide fitness advantages. Changes in hydranth architecture in the hydroid Cordylophora caspia or variations in size in the anal papillae of (...) insect larvae upon changes in medium salinity may be adaptive or not. The restructuring of salt glands in ducklings upon salt‐loading is an example of phenotypic plasticity which indeed seems beneficial. As the genomes of model species are recently sequenced and the animals are easy to rear, these species are suitable study objects to investigate the biological significance of phenotypic plasticity and to study potential epigenetic and other mechanisms underlying phenotypic changes.

In this paper, we aim to show that the framework of embedded, distributed, or extended cognition offers new perspectives on social cognition by applying it to one specific domain: the psychology of memory. In making our case, first we specify some key social dimensions of cognitive distribution and some basic distinctions between memory cases, and then describe stronger and weaker versions of distributed remembering in the general distributed cognition framework. Next, we examine studies of social influences on memory in cognitive (...) psychology, and identify the valuable concepts and methods to be extended and embedded in our framework; we focus in particular on three related paradigms: transactive memory, collaborative recall, and social contagion. Finally, we sketch our own early studies of individual and group memory developed within our framework of distributed cognition, on social contagion of autobiographical memories, collaborative flashbulb memories, and memories of high school at a high school reunion. We see two reciprocal benefits of this conceptual and empirical framework to social memory phenomena: that ideas about distributed cognition can be honed against and tested with the help of sophisticated methods in the social cognitive psychology of memory; and conversely, that a range of social memory phenomena that are as yet poorly understood can be approached afresh with theoretically motivated extensions of existing empirical paradigms.

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants’ generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to generate properties about novel animals and artifacts (Experiment 1: real animals/artifacts; Experiments 2 and 3: matched pairs of maximally similar, novel animals/artifacts). Data demonstrate that even without prior knowledge about these items, the (...) likelihood of producing a generic is significantly greater for animals than artifacts. These results leave open the question of whether this pattern is the product of experience and learned associations or instead a set of early-developing theories about animals and artifacts.

Generic statements express generalizations about categories and present a unique semantic profile that is distinct from quantified statements. This paper reports two studies examining the development of children's intuitions about the semantics of generics and how they differ from statements quantified by all, most, and some. Results reveal that, like adults, preschoolers recognize that generics have flexible truth conditions and are capable of representing a wide range of prevalence levels; and interpret novel generics as having near-universal prevalence implications. Results further (...) show that by age 4, children are beginning to differentiate the meaning of generics and quantified statements; however, even 7- to 11-year-olds are not adultlike in their intuitions about the meaning of most-quantified statements. Overall, these studies suggest that by preschool, children interpret generics in much the same way that adults do; however, mastery of the semantics of quantified statements follows a more protracted course.

Concussion is a form of mild traumatic brain injury that can occur as a result of contact to the head or other parts of the body that causes a rapid acceleration-deceleration force to the brain that may cause a functional disturbance in an individual’s ability to concentrate or learn new information. Contrary to popular belief, it is not a bruise to the brain, and there is usually nothing detectable on standard imaging such as a computed tomography or magnetic resonance imaging. (...) Symptoms and signs are therefore important to detect and include decreased levels of consciousness, headache, nausea, difficulty concentrating, memory loss, and poor coordination. These signs and symptoms usually occur within minutes after the injury but may also appear several hours or even days later. (shrink)

There are increasing concerns that research regulatory requirements exceed those required to manage risks, particularly for low- and negligible-risk research projects. In particular, inconsistent documentation requirements across research sites can delay the conduct of multi-site projects. For a one-year, negligible-risk project examining biobank operations conducted at three separate Australian institutions, we found that the researcher time required to meet regulatory requirements was eight times greater than that required for the approved research activity. In total, 76 business days were required to (...) obtain the necessary approvals, and site-specific processes required twice as long as primary Human Research Ethics Committee and Research Governance Office processes. We describe the impact of this administrative load on the conduct of a one-year, externally-... (shrink)

BackgroundIn clinical research, obtaining informed consent from participants is an ethical and legal requirement. Conveying the information concerning the study can be done using multiple methods yet this step commonly relies exclusively on the informed consent form alone. While this is legal, it does not ensure the participant’s true comprehension. New effective methods of conveying consent information should be tested. In this study we compared the effect of different methods on the knowledge of caregivers of participants of a clinical trial (...) on Pemba Island, Tanzania.MethodsA total of 254 caregivers were assigned to receive (i) a pamphlet (n = 63), (ii) an oral information session (n = 62) or (iii) a pamphlet and an oral information session (n = 64) about the clinical trial procedures, their rights, benefits and potential risks. Their post-intervention knowledge was assessed using a questionnaire. One group of caregivers had not received any information when they were interviewed (n = 65).ResultsIn contrast to the pamphlet, attending an information session significantly increased caregivers’ knowledge for some of the questions. Most of these questions were either related to the parasite (hookworm) or to the trial design (study procedures).ConclusionsIn conclusion, within our trial on Pemba Island, a pamphlet was found to not be a good form of conveying clinical trial information while an oral information session improved knowledge. Not all caregivers attending an information session responded correctly to all questions; therefore, better forms of communicating information need to be found to achieve a truly informed consent.

This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast. The editors argue that despite a deep history of conflict in the region surrounding evolution, there is a wealth of evolution research taking place—from biodiversity in species to cultural evolution and human development. In fact, scientists, educators, and researchers from around the United States have found their niche in the South, (...) where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

Introduction The goal of this project was to develop and validate a new tool to evaluate learners' knowledge and skills related to research ethics. Methods A core set of 50 questions from existing computer-based online teaching modules were identified, refined and supplemented to create a set of 74 multiple-choice, true/false and short answer questions. The questions were pilot-tested and item discrimination was calculated for each question. Poorly performing items were eliminated or refined. Two comparable assessment tools were created. These assessment (...) tools were administered as a pre-test and post-test to a cohort of 58 Indian junior health research investigators before and after exposure to a new course on research ethics. Half of the investigators were exposed to the course online, the other half in person. Item discrimination was calculated for each question and Cronbach's α for each assessment tool. A final version of the assessment tool that incorporated the best questions from the pre-/post-test phase was used to assess retention of research ethics knowledge and skills 3 months after course delivery. Results The final version of the REKASA includes 41 items and had a Cronbach's α of 0.837. Conclusion The results illustrate, in one sample of learners, the successful, systematic development and use of a knowledge and skills assessment tool in research ethics capable of not only measuring basic knowledge in research ethics and oversight but also assessing learners' ability to apply ethics knowledge to the analytical task of reasoning through research ethics cases, without reliance on essay or discussion-based examination. These promising preliminary findings should be confirmed with additional groups of learners. (shrink)

This article explores accusations as collaboratively accomplished in classroom peer interactions in the absence of a teacher. The analysis shows how the children use local classroom rules and teacher authority as resources and warrants to invoke multi-layered moral orders and identities, and hold one child accountable through accusations about their behavior. The accused children are categorized in a duplicative way with morally degrading descriptions and as out-group members. This article argues that understanding children’s accusations requires understanding of how such interactions (...) compose and reflect the school context that is co-produced through the implementation of accountable ways in which to behave.

BackgroundCurrent guidelines do not clearly outline when assent should be attained from paediatric research participants, nor do they detail the necessary elements of the assent process. This stems from the fact that the fundamental justification behind the concept of assent is misunderstood. In this paper, we critically assess three widespread ethical arguments used for assent: children’s rights, the best interests of the child, and respect for a child’s developing autonomy. We then outline a newly-developed two-fold justification for the assent process: (...) respect for the parent’s pedagogical role in teaching their child to become an autonomous being and respect for the child’s moral worth.DiscussionWe argue that the ethical grounding for the involvement of young children in medical decision-making does not stem from children’s rights, the principle of best interests, or respect for developing autonomy. An alternative strategy is to examine the original motivation to engage with the child. In paediatric settings there are two obligations on the researcher: an obligation to the parents who are responsible for determining when and under what circumstances the child develops his capacity for autonomy and reasoning, and an obligation to the child himself. There is an important distinction between respecting a decision and encouraging a decision. This paper illustrates that the process of assent is an important way in which respect for the child as an individual can be demonstrated, however, the value lies not in the child’s response but the fact that his views were solicited in the first place.SummaryThis paper demonstrates that the common justifications for the process of assent are incomplete. Assent should be understood as playing a pedagogical role for the child, helping to teach him how specific decisions are made and therefore helping him to become a better decision-maker. How the researcher engages with the child supports his obligation to the child’s parents, yet why the researcher engages with the child stems from the child’s moral worth. Treating a child as having moral worth need not mean doing what they say but it may mean listening, considering, engaging or involving them in the decision. (shrink)

Generic statements (e.g., “Birds lay eggs”) express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as “Lorches have purple feathers” as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence (...) levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics’ meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse. (shrink)

Adolescence is an important developmental period marked by a transition from primarily parental-controlled eating to self-directed and peer-influenced eating. During this period, adolescents gain autonomy over their individual food choices and eating behavior in general. While parent-feeding practices have been shown to influence eating behaviors in children, little is known about how these relationships track across adolescent development as autonomy expands. The purpose of this qualitative study was to identify factors that impact food decisions and eating autonomy among adolescents. Using (...) the food choice process model as a guide, four focus groups were conducted with 34 adolescents. Focus group discussion was semi-structured, asking teens about influences on their food choices across different food environments, their involvement with food purchasing and preparation, and perceived control over food their choices. Focus group transcripts were analyzed using deductive and inductive code creation and thematic analysis. This study found six leading influences on adolescents' food choices and identified additional factors with prominence within specific environmental contexts. This study distinguished a broader spectrum of factors influencing adolescent food choice that extend beyond “convenience” and “taste” which have previously been identified as significant contributors. The degree of control that teens reported differed by eating location, occasion, and social context. Finally, adolescents demonstrated various levels of engagement in behaviors related to their eating autonomy. Identifying the emergent themes related to adolescent autonomy was the first step toward the goal of developing a scale to evaluate adolescent eating autonomy. (shrink)

A PIRATARIA COMO CONDUTA SOCIALMENTE ACEITA: UM ESTUDO DO CASO MEGAFILMES HD.

IntroductionAcademic integrity policy that is inaccessible, ambiguous or confusing is likely to result in inconsistent policy enactment. Additionally, policy analysis and development are often undertaken as top down processes requiring passive acceptance by users of policy that has been developed outside the context in which it is enacted. Both these factors can result in poor policy uptake, particularly where policy users are overworked, intellectually critical and capable, not prone to passive acceptance and hold valuable grass roots intelligence about policy enactment.Case (...) descriptionThe case study presented in this paper describes the actions of a community of practice at a regional Australian university to deconstruct and translate ambiguous academic integrity policy into a suite of accessible academic integrity resources that were intelligible to staff and students, and which assisted academic staff to consistently enact policy. The paper narrates the formation of the CoP, the tangible and intangible value it created, the social learning practices enacted by its members, its grassroots policy work and the material resources produced from that work.Discussion and evaluationAn evaluation of the CoP was conducted using a value creation framework to explore its immediate value, potential value, applied value, realised value, and reframing value. These values were considered at each stages of the CoP’s lifespan. The evaluation was a useful process that demonstrated the wide-ranging value created by the CoP. Six insights were drawn from the evaluation which promote understanding of the value created for a university by a CoP, particularly in contributing to academic integrity culture over a sustained period of time.ConclusionsThis paper contributes to a research gap on specific examples of discretion within rule-based systems. It illustrates how academics and members of the CoP used their discretion to interpret and enact academic integrity policy within a higher education setting. Drawing from the evaluation of the CoP we argue for greater understanding of the grass-roots contribution of academic and professional staff to academic integrity policy translation and enactment.

This paper explores the relationship between dignity and robot care for older people. It highlights the disquiet that is often expressed about failures to maintain the dignity of vulnerable older people, but points out some of the contradictory uses of the word ‘dignity’. Certain authors have resolved these contradictions by identifying different senses of dignity; contrasting the inviolable dignity inherent in human life to other forms of dignity which can be present to varying degrees. The Capability Approach (CA) is introduced (...) as a different but tangible account of what it means to live a life worthy of human dignity. It is used here as a framework for the assessment of the possible effects of eldercare robots on human dignity. The CA enables the identification of circumstances in which robots could enhance dignity by expanding the set of capabilities that are accessible to frail older people. At the same time, it is also possible within its framework to identify ways in which robots could have a negative impact, by impeding the access of older people to essential capabilities. It is concluded that the CA has some advantages over other accounts of dignity, but that further work and empirical study is needed in order to adapt it to the particular circumstances and concerns of those in the latter part of their lives.

Emotion plays a significant role in our reasoning even without awareness, perhaps especially for individuals who have difficulties tolerating strong, negative emotions. Opportunity for reflection may help such individuals decide when emotions should influence reasoning. Two studies attempted to clarify the relationships among reasoning, emotions, and emotion tolerance (measured with the Affect Intolerance Scale). The first examined the effect of affect intolerance on a reasoning task. Participants were asked to determine whether conclusions logically followed from both emotional and neutral if–then (...) statements. Emotion had a small effect on performance on the reasoning task, unmoderated by affect intolerance. The second study examined whether reflection on emotional responses impacts performance on the same reasoning task. Participants asked to reflect on their emotions performed more poorly on the reasoning task than participants asked to reflect on the task’s cognitive aspects. People who endorse greater affect tolerance performed better in the cognitive reflection condition than the emotional reflection condition. People with less tolerance performed the same in both conditions. Overall, these studies support previous findings that emotion can negatively impact performance on reasoning tasks but suggest a more complex relationship for affect intolerance. (shrink)

This article draws on the work of the philosopher Emmanuel Levinas to offer a fresh insight into the law’s response to the issue of whistleblowing. In order to achieve this we briefly outline the main themes of his philosophy of otherness which insists that the very essence of ethics springs from the subjection (a succumbing) of the Subject to the ethical call of the Other. We provide a short description of the UK law on whistleblowing before undertaking a Levinasian reading (...) of a particular case in order to consider the dilemma that confronts the judge in framing an ethical response to the whistleblower as Other.

We propose that marketing of unhealthy foods and beverages to Black and Latino consumers results from the intersection of a business model in which profits come primarily from marketing an unhealthy mix of products, standard targeted marketing strategies, and societal forces of structural racism, and contributes to health disparities.

Osiurak and Reynaud offer a unified cognitive approach to cumulative technological culture, arguing that it begins with non-social cognitive skills that allow humans to learn and develop new technical information. Drawing on research focusing on how children acquire knowledge through interactions others, we argue that social learning is essential for humans to acquire technical information.

PRIVATIZAÇÃO DAS ÁGUAS: UMA ANÁLISE NA PERSPECTIVA LATINO AMERICANA A PARTIR DOS DIREITOS HUMANOS FUNDAMENTAIS.

The growing proportion of elderly people in society, together with recent advances in robotics, makes the use of robots in elder care increasingly likely. We outline developments in the areas of robot applications for assisting the elderly and their carers, for monitoring their health and safety, and for providing them with companionship. Despite the possible benefits, we raise and discuss six main ethical concerns associated with: (1) the potential reduction in the amount of human contact; (2) an increase in the (...) feelings of objectification and loss of control; (3) a loss of privacy; (4) a loss of personal liberty; (5) deception and infantilisation; (6) the circumstances in which elderly people should be allowed to control robots. We conclude by balancing the care benefits against the ethical costs. If introduced with foresight and careful guidelines, robots and robotic technology could improve the lives of the elderly, reducing their dependence, and creating more opportunities for social interaction.

How do the ways we argue represent a practical philosophy or a way of life? Are concepts of character and ethos pertinent to our understanding of academic debate? In this book, Amanda Anderson analyzes arguments in literary, cultural, and political theory, with special attention to the ways in which theorists understand ideals of critical distance, forms of subjective experience, and the determinants of belief and practice. Drawing on the resources of the liberal and rationalist tradition, Anderson interrogates the limits (...) of identity politics and poststructuralism while holding to the importance of theory as a form of life. Considering high-profile trends as well as less noted patterns of argument, The Way We Argue Now addresses work in feminism, new historicism, queer theory, postcolonialism, cosmopolitanism, pragmatism, and proceduralism. The essays brought together here--lucid, precise, rigorously argued--combine pointed critique with an appreciative assessment of the productive internal contests and creative developments across these influential bodies of thought. Ultimately, The Way We Argue Now promotes a revitalized culture of argument through a richer understanding of the ways critical reason is practiced at the individual, collective, and institutional levels. Bringing to the fore the complexities of academic debate while shifting the terms by which we assess the continued influence of theory, it will appeal to readers interested in political theory, literary studies, cultural studies, gender studies, and the place of academic culture in society and politics.

This paper primarily explores the ethical debate surrounding the use of memory erasure for therapeutic ends. It argues that procedures such as kinase inhibition therapy, which can entail memory erasure in the individual, incur a high cost in terms of the integrity of our individual identities, thus jeopardizing our claim to individual rights and accountability. Therefore, we should reserve such therapies for the extreme cases in which the procedures have the potential to actually restore a person’s autonomy. Furthermore, this paper (...) goes on to explore which situations might fit this criterion, while still accounting for the cost of memory erasure in each instance. (shrink)

The text here summarized aims to examine the tragedy Medea of Euripides, from the gender concept stand point, trying to emphasize the gender relationships in it described and the tactics of the female universe in it reported.

This qualitative study focused on how two women African American teachers understand the purpose of teaching social studies and citizenship. The multiple identities as African American women and teachers along with their knowledge of African American history impacted the way notions of citizenship were understood and taught to students. The teachers drew on tenets of Black Feminist thought to make sense of construct of citizenship. Instead of conveying traditional notions of citizenship that include personal responsibility, patriotism, and membership to the (...) nation state, they rejected these constructs of citizenship and understood their role as social studies teachers to instill notions of community membership and agency as aspects of citizenship. African American teacher's alternative notions of citizenship may provide a framework by which reconceptualized multiple views of American citizenship may be presented. (shrink)

This paper is a response to Fagan's argument that Levinas's attempt to build an ethics, separated from politics, is misconceived. I take issue with her claim that the separation is untenable because the Third is always present in the encounter with the Other. I maintain that this conclusion fails to appreciate Levinas's attempt to resolve the apparent contradictions in his greatest work, Otherwise than Being. My approach, consciously in the Levinasian tradition, is elliptical in the sense that I seek not (...) simply to explain why her thesis is a misreading of his thinking but to demonstrate why the separation of ethics from politics is essential to it. Levinas's quest for an unproblematized ethics is a response to the collapse of belief in a transcendental deity, an inevitable outcome of the Shoah, and leads him to locate the divine in the face of the Other. This has to be a solitary encounter, a dyadic relation of Self to the Other, as the pre-cognitive genesis of ethics that accords precedence of the Good over the classical philosophical obsession with the True.

As the cognitive revolution was slow to come to the study of animal behavior, the vast majority of what we know about primate cognition has been discovered in the last 30 years. Building on the recognition that the physical and social worlds of humans and their living primate relatives pose many of the same evolutionary challenges, programs of research have established that the most basic cognitive skills and mental representations that humans use to navigate those worlds are already possessed by (...) other primates. There may be differences between humans and other primates, however, in more complex cognitive skills, such as reasoning about relations, causality, time, and other minds. Of special importance, the human primate seems to possess a species-unique set of adaptations for “cultural intelligence,” which are broad reaching in their effects on human cognition. (shrink)

The current study examined the effects of cuing autobiographical memory retrieval in 12 older participants with dementia through immersion into a historically authentic environment that recreated the material and cultural context of the participants’ youth. Participants conversed in either an everyday setting or a museum setting furnished in early twentieth century style while being presented with condition matched cues. Conversations were coded for memory content based on an adapted version of Levine, Svoboda, Hay, Winocur, and Moscovitch coding scheme. More autobiographical (...) memories were recalled in the museum setting, and these memories were more elaborated, more spontaneous and included especially more internal details compared to memories in the control condition. The findings have theoretical and practical implications by showing that the memories retrieved in the museum setting were both quantitatively and qualitatively different from memories retrieved during a control condition.
