Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

This essay compares Sikh and Christian thought about and practices of hospitality in light of the global refugee crisis. It aims to show how both practices of hospitality, and religious ethical thought about hospitality, can be enhanced by dialogue between traditions. The refugee crisis arises out of a global failure of hospitality, and the type of hospitality refugees most fundamentally need is that which confers membership in a political community. Comparing Christian and Sikh ethics of hospitality provides guidance toward building (...) rooted religious communities that welcome outsiders, including by incorporating them into political communities. In particular, Christians who hold social power and privilege can better fulfill ethical mandates of hospitality by looking to the example of Sikhs and other marginalized groups. Sikhs have often built communities through acts of hospitality and welcomed outsiders without fear, even in contexts where their own belonging is questioned and their own security is under threat.

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who lives and who (...) dies. (shrink)

In this paper I will present the accounts of two influential contemporary moral philosophers, Grace Clement and Amartya Sen, to argue for the social context and inter-related nature of autonomy. In fact, there can be no autonomy for anyone without a loving and caring social environment that actively promotes independent thinking and capacity empowerment among people. This social dimension of autonomy has often been ignored by traditional theorists, who have considered autonomy to be an individual accomplishment that is a function (...) of an individual's will power, intellectual ability, or self-discipline and virtue.

This paper compares Kant's positions on space, time, the relational character of noumena, and the relational character of the self, with the somewhat similar accounts of those things in two philosophers of the Kyoto school: Keiji Nishitani and Nishida Kitaro. I will argue that the philosophers of the Kyoto school had a more coherent and better integrated account of those ideas, that was open to Kant. I think that the comparison both clarifies Kant's position on these topics, and elucidates the (...) topics. (shrink)

Clathrin‐mediated endocytosis is a major route for the retrieval of plasma‐membrane cargoes, and defects of this process can cause catastrophic human dysfunctions. However, the processes governing how a clathrin‐coated profile (ccp) is initiated are still murky. Despite an ever‐growing cast of molecules proposed as triggers of ccp nucleation and increasingly sophisticated bioimaging techniques examining clathrin‐mediated endocytosis, it is yet unknown if ccp formation is governed by a universal mechanism. A recent paper by Cocucci et al. has tracked single‐molecule events to (...) identify that stable accumulation of ccps requires the near‐simultaneous arrival of two AP2 adaptors bridged by one clathrin triskelion. This commentary examines the role of AP2 in cargo‐mediated endocytosis in the light of recent advances in biophotonics, chemical inhibitors and genetics, examines the claims of other molecules to be the initiators of ccp formation and proposes future directions in research into this topic.Editor's suggested further reading in BioEssays: The evolution of dynamin to regulate clathrin‐mediated endocytosis AbstractClathrin‐mediated endocytosis: What works for small, also works for big Abstract.

When people manipulate a moving object, such as writing with a pen or driving a car, they experience their actions as intimately related to the object’s motion, that is they perceive control. Here, we tested the hypothesis that observers would feel more control over a moving object if an unrelated task drew attention to a location to which the object subsequently moved. Participants steered an object within a narrow path and discriminated the color of a flash that appeared briefly close (...) to the object. Across two experiments, participants provided higher ratings of perceived control when an object moved over a flash’s location than when an object moved away from a flash’s location. This result suggests that we use the location of spatial attention to determine the perception of control. If an object goes where we are attending, we feel like we made it go there. (shrink)

From the earliest application of modern randomized controlled trials in medical research, scientists and observers have deliberated the ethics of randomly allocating study participants to trial control arms. Adaptive RCT designs have been promoted as ethically advantageous over conventional RCTs because they reduce the allocation of subjects to what appear to be inferior treatments. Critical assessment of this claim is important, as adaptive designs are changing medical research, with the potential to significantly shift how clinical trials are conducted. Policy-makers are (...) swiftly moving to encourage greater use of adaptive designs. In 2016, the newly enacted 21st Century Cures Act instructed the Food and Drug Administration to help product sponsors incorporate adaptive methods into proposed clinical trial protocols and applications for investigational drugs and also biological products. In this article, we review the ethical justifications commonly offered for adaptive designs, explore these arguments in the context of actual trials, and contend that clinical equipoise is a useful standard for adaptive-trial ethics. We distinguish between theoretical and clinical equipoise and explain why ethical arguments related to adaptive trials tend to focus on the former. Yet we contend that theoretical equipoise can be an unreliable standard for adaptive ethics. While we contend that clinical equipoise is the most critical principle for the primary ethical concerns posed by adaptive trials, we suggest ethical approaches to deal with some additional concerns unique to adaptive designs.

One of the hallmarks of American Indian colonial experience was the arrival of Christian missionaries. The response of Native cultures to missionization has been complex, with some resisting the white man's religion and others embracing it. Throughout their contact with Christianity, however, many American Indians appropriated its stories on their own terms and for their own purposes. Stories about Jesus comprise one of the most important sites for this appropriation. This essay examines the ways in which the cultural production of (...) American Indian women makes a crucial intervention in the debates about Jesus' identity. It argues that the narrative negotiations of Native women in the contact zone of Euro-American encounters transform the theological category of christology. (shrink)

Determining appropriate authorship recognition in student-faculty collaborative research is a complex task. In this quantitative study, responses from 1346 students and faculty in education and some social science disciplines at 36 research-intensive institutions in the United States were analyzed to provide a description of current and recommended practices for authorship in student-faculty collaborative research. The responses revealed practices and perceptions that are not aligned with ethical guidelines and a lack of consensus among respondents about appropriate practice. Faculty and student respondents (...) agreed that students deserve more authorship recognition than they get in common practice but they did not agree on the appropriate authorship arrangement for several of the collaborative scenarios described in the study or on the relative value of various contributions to research projects. The misalignment with ethical codes and lack of consensus among the respondents is problematic because student-faculty collaborative research is common and authored publications are powerful indicators of research competency. With these detailed results, students and faculty can better anticipate areas where their perspectives are likely to differ and faculty can work to clarify ambiguous expectations. (shrink)

Millions of Chinese children learn English at increasingly younger ages. Yet when it comes to measuring proficiency, educators, and researchers rely on assessments that have been developed for L1 learners and/or for different cultural contexts, or on non-validated, individually designed tests. We developed the Assessment of Chinese Children’s English Vocabulary test to address the need for a validated, culturally appropriate receptive vocabulary test, designed specifically for young Chinese learners. The items are drawn from current teaching materials used in China, and (...) the depictions of people and objects are culturally appropriate. We evaluated the instrument’s reliability and validity in two field tests with a combined sample size of 1,092 children analyses show that the ACCE-V is sufficiently sensitive to capture different proficiency levels and that it has good psychometric properties. ACCE-V scores were correlated with Peabody Picture Vocabulary Test scores, indicating concurrent validity. We found that children’s age and English learning experience can significantly predict the scores of ACCE-V, but the effect of English learning experience is greater. The ACCE-V thus offers an alternative to existing vocabulary tests. We argue that culturally appropriate assessments like the ACCE-V are fairer to learners and help promote an English learning and teaching environment that is less dominated by Western cultures and native speaker norms.

This paper faces the projections of the moral philosophy of Cicero on medieval scholastic ethics; it examines the influence of Cicero's writings dealing with treatment of the justificating way of moral behavior starting from natural human inclinations. First, the article analyses the philosophical elaboration of the theme in the field of ciceronian thinking. Second, already inside the frame of medieval elaborations, the article deals with projections of ciceronian tradition around natural human inclinations in their relations with moral life, in the (...) philosophical developments of Thomas Aquinas about origins of virtue and natural law.

This study examined the role of temporal orientation and affective frame in the execution of ethical decision-making strategies. In reflecting on a past experience or imagining a future experience, participants thought about experiences that they considered either positive or negative. The participants recorded their thinking about that experience by responding to several questions, and their responses were content-analyzed for the use of ethical decision-making strategies. The findings indicated that a future temporal orientation was associated with greater strategy use. Likewise, a (...) positive affective frame was associated with greater strategy use. Future orientation may permit better strategy execution than a past orientation because it facilitates more objective, balanced contemplation of the reflected-upon situation and minimizes potential self-threat associated with past behavior. A positive affective frame likely improves strategy execution because it facilitates active analysis of the experience. Future directions and implications of these findings are discussed. (shrink)
