Microbes in the gastrointestinal tract are under selective pressure to manipulate host eating behavior to increase their fitness, sometimes at the expense of host fitness. Microbes may do this through two potential strategies: (i) generating cravings for foods that they specialize on or foods that suppress their competitors, or (ii) inducing dysphoria until we eat foods that enhance their fitness. We review several potential mechanisms for microbial control over eating behavior including microbial influence on reward and satiety pathways, production of (...) toxins that alter mood, changes to receptors including taste receptors, and hijacking of the vagus nerve, the neural axis between the gut and the brain. We also review the evidence for alternative explanations for cravings and unhealthy eating behavior. Because microbiota are easily manipulatable by prebiotics, probiotics, antibiotics, fecal transplants, and dietary changes, altering our microbiota offers a tractable approach to otherwise intractable problems of obesity and unhealthy eating.

"He completed the assignment in two phases: The photographs made during the first phase capture the natural ruggedness of the terrain and establish its relationship to the developed neighboring enclaves. Those made during the second phase not only record the actual construction process but also reveal Deal's personal perspective on the qualities of light and the creation of form. Represented in this book as a selection from the resulting portfolio, Topos, a Greek word meaning place, site, position, and occasion - (...)

Wayfinding is generally understood as the process of purposefully navigating to distant and non-visible destinations. Within this broad framework, uninformed searching entails finding one’s way to a target destination, in an unfamiliar environment, with no knowledge of its location. Although a variety of search strategies have been previously reported, this research was largely conducted in the laboratory or virtual environments using simplistic and often non-realistic situations, raising questions about its ecological validity. In this study, we explored how extant findings on (...) searching translate to a real-world environment, using a phenomenologically informed experiment. Our findings demonstrate a previously undescribed complex and dynamic interplay of different search strategies. Importantly, our results reveal that: (i) the presence of other people is importantly entangled with the process of searching; and (ii) people frequently probe and switch between search strategies based on local environmental characteristics. Together, our results reveal that search behaviour is critically dependent on environmental features and that searching in complex real-world settings should not be conceptualised as depending on a simple singular strategy. This raises questions about the dominance of laboratory-based experiments and their narrow cognitivist framework, highlighting the value of studying wayfinding in the real world. (shrink)

The subject of this book is young children's emotional-social learning and development within early childhood care and education settings in Aotearoa-New Zealand. The focus on emotional complexity fills a gap in early childhood care and education research where young children are frequently framed narrowly as 'learners,' ignoring the importance of emotional functioning and the feelings with which children make sense of themselves and the world. This book draws on original data in the form of narrative-like framed events to creatively illustrate (...) the complexities in children's diverse ways of feeling, thinking, playing, being, and becoming. Events illuminate the feelings and meanings of observed experiences in holistic and contextualised gestalts. Awareness of unconscious processes, the feeling of feelings, and cultural dimensions of development and meaning-making are addressed. The book emphasises the emergent and psychodynamic nature of children's development and learning with strong links to the role of play and playfulness in the events, drawing on two ethnographically inspired research projects that present theory, experience and practice in real-life events.

The Quest for Learning: How to Maximize Student Engagement affirms that traditional classroom learning experiences, in which you plan lessons and voice instruction at the front of the room, do not meet 21st century students learning needs. Questing is a customizable pedagogy that readers and their students together tailor to a students abilities, needs, and interests. Side by side, and aligned with learning targets, readers learn how teachers and students determine what a student will learn about and at what pace. (...) Authors Marie Alcock, Michael Fisher, and Allison Zmuda propose three tenets of engagement (1) the learner engages with relevant, worthy inquiries and experiences that are interesting or emotionally gripping, (2) the learner engages in an active, intentional cycle with clear goals and right-sized, actionable steps, and (3) the learner engages in social, collaborative opportunities that grow expertise that allow students to take ownership of their learning. To further that ownership, students decide which design type they want to use to explore their quest topic (1) question, (2) game, or (3) network. Students then pursue lines of inquiry, design or play games, or communicate with peers and experts in online and physical spaces. Each is a method for becoming an expert on chosen topics. (shrink)

There has recently been an explosion of interest in rational and moral choice under evaluative uncertainty—uncertainty about values or reasons. However, the dominant views on such choice have at least three major problems: they are overly demanding, they are incompatible with supererogation, and they cannot be applied to agents with credence in indeterminate evaluative theories. The authors propose a unified view that solves all these problems. According to this view, permissible options maximize expected utility relative to permissible preferences, and different (...) kinds of permissibility for options correspond to different kinds of permissibility for preferences. Thus, rationally permissible options maximize expected utility relative to rationally permissible preferences, and morally permissible options maximize expected utility relative to morally permissible preferences. The authors argue that this view has more plausible implications than its rivals not only under evaluative uncertainty but also under ordinary uncertainty. (shrink)

Our ability to survive in a world beset by looming global perils depends ultimately on our collective will to harness our intellects and change our behaviors. In order to respond appropriately, people must first believe that serious problems exist, that there are potential solutions, and that they have a role to play in finding and implementing them. Without such beliefs, individual change is unlikely. In order to promote belief change, it is important to understand how beliefs are learned, what their (...) functions are, and why they are so often resistant to change. These issues are discussed in this article, along with the role that social dilemmas play in inhibiting individually prosocial behavior. (shrink)

My criticisms of parapsychology are neither based on its subject matter per se, nor simply on a charge of sloppy research, but rather on the whole pattern of theory and research in this domain. The lack of a positive definition of psi, the use of ad hoc principles such as psi-missing and the experimenter psi effect to account for failures to confirm hypotheses, and the failure to produce a single phenomenon that can be replicated by neutral investigators are among the (...) major problems that keep parapsychology outside regular science. Glicksohn and I agree that anomalous experiences should be investigated. (shrink)

_Teachers as Researchers_ urges teachers - as both producers and consumers of knowledge - to engage in the debate about educational research by undertaking meaningful research themselves. Teachers are being encouraged to carry out research in order to improve their effectiveness in the classroom, but this book suggests that they also reflect on and challenge the reductionist and technicist methods that promote a 'top down' system of education. It argues that only by engaging in complex, critical research will teachers rediscover (...) their professional status, empower their practice in the classroom and improve the quality of education for their pupils. Now re-released to introduce this classic guide for teachers, the new edition of _Teachers as Researchers_ now also includes an introductory chapter by Shirley R. Steinberg that sets the book within the context of both the subject and the historical perspective. In addition, she also provides information on some key writing that extends the bibliography of this influential book thereby bringing the material fully up to date with current research. Postgraduate students of education and experienced teachers will find much to inspire and encourage them in this definitive book. (shrink)

Is there a world beyond the senses? Can we perceive future events before they occur? Is it possible to communicate with others without need of our complex sensory-perceptual apparatus that has evolved over hundreds of millions of years? Can our minds/souls/personalities leave our bodies and operate with all the knowledge and information-processing ability that is normally dependent upon the physical brain? Do our personalities survive physical death?

Externalism with regard to mental content says that in order to have certain types of intentional mental states (e.g. beliefs), it is necessary to be related to the environment in the right way.

The answer is surprising, and what we're about to learn will wake us up to a reality most of us never knew existed.The reason we're so oblivious is because we've all been operating at human speed, relying on our own physical power and our five senses. But there is something extremely important we've all been missing. It holds the key to everything good--the key to life, success, happiness, peace of mind, and understanding beyond our wildest imagination. It's perhaps the best-kept (...) secret in the history of mankind and it packs a staggering, invigorating message that can change your life for the better--improving understanding, eliminating anxiety, and helping to extend your living years indefinitely. All we have to do is open our eyes and ears.We're all inundated with this secret at all times. It's present in our favorite songs and movies, the stories we tell our children, and even in every commercial campaign! The secret is broadcast in famous news stories including the coronavirus pandemic, the sinking of the Titanic, or the collapse of the World Trade Center on 9/11. It's in ordinary life activities such as breathing, sleeping, waking up, traveling, sex, and getting married and changing one's name.Now, bestselling author and award-winning journalist Joe Kovacs reveals the solution--cracking the divine code that shifts our minds from operating at slow, human speed and making the jump to the incredibly quick "God speed."Hundreds of ancient mysteries and prophecies are instantly unsealed as the master key that unlocks the mystery of everything is now in your hands.

Let me begin with the standard apology and expression of regret for not being able to comment on all of the intriguing and illuminating themes in Professor Churchland’s paper. I should at least note, though, my enthusiasm for his suggestive discussion of the complexity of all concepts, for his detailed portrayal of the resources of neural network models, and for his attempt to deflate our Cartesian pretensions by focusing on the commonality between human and infrahuman cognition. I restrict my developed (...) remarks to two different topics: First, I have some thoughts about Churchland’s central thesis with respect to the nature of epistemology. Second, I want to say something about the pursuit of epistemology if we follow Churchland’s lead. (shrink)

This chapter argues that, under certain conditions, forming an intention makes an action rational which would otherwise not have been rational, since intentions (together with beliefs) in and of themselves provide deductive reasons for further intentions and actions, an argument which builds on previous work by R M Hare, Michael Bratman and others, It also provides an articulation and defense of the concept of "minimally constrained maximization" as a unified general solution to the well-known paradoxes of rationality, including the paradox (...) of deterrence and the prisoner's dilemma.

Since the days of the Ancient Greeks, history has been perceived as the academic study of the past. Unfortunately, it has generally been taught as a litany of rigid, boring facts intended to be accepted rather than questioned. This has been reinforced for decades by weighty textbooks that overwhelm the reader with mind-numbing details presented in a chronological sequence. The end result is that students see little relevance of what they learn in history class to the real world, and many (...) simply struggle to stay awake. Compared to other subjects taught at the secondary level, history is frequently judged to be the most boring. This is largely because it is viewed as an intellectually lifeless subject that presents few opportunities for active engagement. (shrink)

This article focuses on Grotius’s treatment of obligations arising from wrongdoing in his Inleidinge. The work has clear parallels with the natural law formulation of the same topic in De Jure Belli ac Pacis, and this article explores the extent of the similarities. It focuses on points of divergence, suggesting that the theoretical coherence of the natural law approach to obligations arising from wrongdoing was challenged primarily by extant legislative enactments. These provided either for region-specific doctrines, or rules that proved (...) difficult to reconcile with the underlying principles of natural law, especially the primacy of fault. While much of the Inleidinge’s treatment of liability arising from wrongdoing is consonant with Grotius’ approach to the topic in De Jure Belli ac Pacis, these discrete points of dissimilarity serve as a reminder of the limits of theoretical accounts of private law.

O objeto deste artigo é a leitura que Claude Geffré faz de Paul Tillich em De Babel a Pentecostes: ensaios de teologia inter-religiosa. O autor recorre à teologia de Tillich para desenvolver uma “hermenêutica do diálogo inter-religioso”, a fim de responder ao desafio do pluralismo religioso para a teologia cristã. O argumento que Geffré encontra é que apenas a partir do paradoxo cristológico, à luz do conceito de “revelação final” e “preocupação última”, a teologia cristã pode responder ao pluralismo religioso (...) sem perder-se de si mesmo. O artigo tem dois momentos: primeiro, uma percepção da obra de Geffré, especialmente a primeira parte, intitulada Não há outro nome, onde está nosso foco; segundo, a análise dos três conceitos de Tillich desenvolvidos por Geffré, procurando identificar e caracterizar acentos da leitura e analisar o resultado dessa leitura à luz das referências na obra de Tillich. Nossa conclusão sublinha a pertinência da teologia de Tillich para a reflexão acerca do problema proposto, tal como Geffré demonstra, e destaca uma crítica a partir do conceito de preocupação última, cuja implicação questiona a positividade desse conceito para uma teologia inter-religiosa, uma vez que seu caráter paradoxal seja relativizado.

This collection assembles Church's referee reports, Fitch's 1963 paper, and nineteen new papers on the knowability paradox.

Although scholars from many disciplines have turned their attention to Russell’s work and appraised its significance for a number of fields, and an extensive literature on him emerged, until this book, first published in 1963, no thorough study on Russell’s contribution to education – an area to which he devoted no small part of his energies – had yet appeared. The book is based on interviews with Russell as well as diligent research in his writings and the sources of his (...) thought and will enlighten all who think seriously about education. It addresses specifically the usefulness of Russell’s thought for American educators, which was challenging as Russell dared to question traditional ends and means of education at the time. (shrink)

There are many cases in which, by making some great sacrifice, you could bring about either a good outcome or a very good outcome. In some of these cases, it seems wrong for you to bring about the good outcome, since you could bring about the very good outcome with no additional sacrifice. It also seems permissible for you not to make the sacrifice, and bring about neither outcome. But together, these claims seem to imply that you ought to bring (...) about neither outcome rather than the good outcome. And that seems very counterintuitive. In this paper, I develop this problem, propose a solution, and then draw out some implications both for how we should understand supererogation and for how we should approach charitable giving.
