Are Our Ideas About Octopus Life Too Anthropomorphic To Help?, Kenneth J. Aitken
Are Our Ideas About Octopus Life Too Anthropomorphic To Help?, Kenneth J. Aitken
Animal Sentience
Our understanding of the evolution and ontogeny of the octopus and its behavioral repertoire in its natural habitat remains rudimentary at best. There are many parallels, but also just as many differences from our models of human biology and ontogeny, making anthropocentric generalizations of limited use in explanation.

A Behavior-Analytic Approach To Understanding Octopus “Mind”, Lindsay R. Mehrkam
Animal Sentience
Mather makes a convincing case for octopus sentience based on a lot of evidence of their complex learning capabilities. It should follow from Mather’s findings that these intelligent invertebrates are worthy of welfare considerations, just as vertebrate species with similar capabilities are. I provide a complementary environment-behavior analysis of how we might understand the world of the octopus more straightforwardly, borrowing from Mather’s examples, to show how to promote opportunities for complex learning and species-typical behaviors in the octopus.

Cephalopod Molluscs, Causal Models, And Curious Minds, Andrew W. Corcoran
Animal Sentience
Mather (2019) presents a compelling case in favour of octopus mind. Surveying an impressive array of empirical literature, she identifies the creature’s playful, inquisitive behaviour as emblematic of a distinctively mental form of agency. I offer an alternative perspective in which curiosity and play are construed as constitutive processes in the emergence of the (predictive) mind.

Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino
Animal Sentience
Mather argues convincingly for the existence of minds in octopuses based largely on laboratory experiments. Many of these experiments are highly invasive and involve mutilation and death. Moreover, octopuses are now being hailed as a “new model” for biological research and are being enthusiastically bred in captivity, both for research and for food. We argue that the compelling evidence for mind in octopuses must be accompanied by intense scrutiny of the ethics that shape how we treat them and that the intrinsic value of their individual lives must be recognized.

‘Mind’ Is An Ill-Defined Concept: Considerations For Future Cephalopod Research, Alexandra Schnell, Giorgio Vallortigara
Animal Sentience
Scientific discussions about the ‘mind’ of an octopus are empirically vacuous and should be confined to folk psychology. This form of labelling is unhelpful for science and should be replaced by specific mechanistic accounts of behavior and associated neural structures, which are amenable to rigorous scientific investigation. Mather provides a detailed review of octopus behavior, but rather than making unquantifiable assumptions about what orchestrates octopus behavior, efforts should focus on investigating cognitive mechanisms that can be measured. In this commentary, we outline two lines of research that include quantifiable methods to facilitate a more robust understanding of cephalopod behaviors and …

The Octopus Mind: Implications For Cognitive Science, Sidney Carls-Diamante

Mather consolidates the case for octopus mind and how it may be structured, shifting the starting point of inquiry from “If octopuses had minds, what would they be like?” to “What is the mind of an octopus like?”.
Octopus Experience, Peter Godfrey-Smith
Octopus Experience, Peter Godfrey-Smith
Animal Sentience
The first part of this commentary attempts to get "inside" the octopus mind a little further than Mather does, drawing on her description of octopus cognition in many places but diverging in others. The second part outlines other disagreements with her account of the animals, especially in the area of social behavior.

The Octopus Mind And The Argument Against Farming It, Jennifer Jacquet, Becca Franks, Peter Godfrey-Smith
Animal Sentience
Mather is convincing about octopuses having ‘a controlling mind, motivated to gather information,’ but stops short of asking what having that mind means for octopus moral standing. One consequence of understanding the octopus mind should be a refusal to subject octopuses to mass production. Octopus farming is in an experimental phase and supported by various countries. We argue that it is unethical because of concerns about animal welfare as well as environmental impacts.
Octopus Intelligence: The Importance Of Being Agnostic, Piero Amodio
Octopus Intelligence: The Importance Of Being Agnostic, Piero Amodio
Animal Sentience
Mather’s (2019) provocative claim that octopuses have a mind hinges on the inference that their striking behavioural flexibility is evidence of “complex” cognitive abilities. I discuss alternative explanations — not to deny the possibility of complexity but to point out that current evidence does not allow us to draw firm conclusions. Only an agnostic approach will lead to the systematic investigation of octopus behaviour and ultimately, greater insights into the cognitive capacities of these fascinating creatures.
Keeping Hold Of Nurse, Andrew Packard
Keeping Hold Of Nurse, Andrew Packard
Animal Sentience
Mather draws from a lifetime devoted to studying individual octopuses in the wild and in aquaria to combine a natural history account of their actions with an argument from design adopted from second-, often third-hand sources. The 'distributed' [decentralised] nervous system said to contrast with that of vertebrates – a premise largely accepted by Mather’s commentators so far – does not reflect the original literature on motor control, nor the facts of comparative anatomy, functional morphology and morphogenesis. Ontogeny is absent. With the help of some old or little-known illustrations from my own participant-observer experimental investigations, I will try here …

What We Don't Know About Cephalopods And How To Define It, Catia Correia Caeiro
Animal Sentience
Despite the reputation of octopuses as intelligent animals, their cognitive abilities seem to be mostly unknown. This should be the starting point of a long process of scientific enquiry about these taxa, which must include discussions on operational definitions first and foremost. Discussing octopus mind might prove fruitless without more basic concepts. Some approaches are suggested here.
Octopus: Multiple Minds Or Just A Slow Thinker?, Shelley A. Adamo
Octopus: Multiple Minds Or Just A Slow Thinker?, Shelley A. Adamo
Animal Sentience
An octopus has more neurons in their peripheral nervous system (PNS) than in their brain. PNS neurons could participate in forming cognitive networks with the central brain in the same way that the cerebellum is now thought to contribute to mammalian cognition. However, cephalopods lack myelinated fibres, which might decrease the ability of the PNS to participate in cognitive networks. The lack of myelinated fibres may also select for a less integrated brain, with an increased emphasis on local information processing. Alternatively, integration may still occur across distant neural centers, but proceed more slowly in cephalopods than in mammals.

Octopus Sentience: Three Criteria, Alix Noël-Guéry

The first question to ask is whether octopuses are sentient, so that, if so, they can be protected. Three consensual criteria to evaluate animal sentience can be applied to the octopus. Octopuses meet all three of them.
What And Where Is An Octopus’S Mind?, Jennifer A. Mather
What And Where Is An Octopus’S Mind?, Jennifer A. Mather
Animal Sentience
It is gratifying to see the thorough discussion of whether octopuses have a mind, though perhaps a mind that is different from those of “higher” vertebrates. It stimulates us to look at the welfare of these animals and challenges us to find better ways to test mindfulness and cognition across animals with widely differing natural histories and sensory and motor capacities.

Aesthetics And Imagining The Octopus’S Mind, André Krebber, Maike Riedinger, Yvette Watt
Animal Sentience
Several commentators on Mather’s target article discuss the challenges of finding adequate cognitive methods and concepts for accessing the mind and experience of octopuses. Building on Godfrey-Smith’s commentary, we propose aesthetics as a way. The arts provide means to perform what Godfrey-Smith calls an “imaginative leap” to access the experience of octopuses, especially mimesis. We are trying to do this in our current project Okto-Lab. Laboratory for Octopus Aesthetics.

Can A Precast Pit Latrine Concrete Floor Withstand Emptying Operations? An Investigation From Malawi., Joshua Mchenga, Rochelle H. Holm
Faculty and Staff Scholarship
For fecal sludge from households in low- and middle-income countries to be treated offsite it needs to be removed, which can be greatly affected by the pit latrine floor design. However, it is unclear whether precast pit latrine concrete floors (latrine slabs) can withstand emptiers and their equipment. To investigate this issue, 28 prefabricated latrine slabs were purchased in two cities of Malawi. They were first visually evaluated, and then their compression strength was tested. Additionally, each seller was asked a series of questions to better understand their business, training, and construction practices. Results showed that households should perform due …

Early in the debate over abortion, opposition to the procedure was primarily described in terms that reflected moral concerns about the protection of “the unborn.” Indeed, much of the media coverage and public discourse describing opposition to abortion since the time of Roe characterizes the movement as focused on securing rights for all human beings from the moment of conception (Huff 2014, 39). However, interviews with activists and movement leaders suggest that antiabortion groups have employed an array of public outreach strategies over time. As seen above, the former director of the antiabortion group National Right to Life …

The Intermedial Politics Of Handwritten Newspapers In The 19th-Century U.S., Mark A. Mattes
Faculty and Staff Scholarship
Handwritten newspapers appeared in a variety of social contexts in the 19th-century U.S.1 The largest extant portion of 19th-century handwritten newspapers emerged from home and school settings. More far-flung examples include those written aboard ships during exploratory and military voyages. Others were produced within institutions such as hospitals and asylums. Such works were written during times of privation, including life in an army regiment or a prisoner-of-war camp during the Civil War. At other times, handwritten newspapers accompanied efforts at westward settlement and transcontinental railway journeys. Impromptu papers could follow in the wake of natural disasters that knocked out print-based …

Background Despite the large number of studies and reviews available, the evidence regarding the biological determinants of physical activity (PA) is inconclusive. In this umbrella review, we summarized the current evidence on the biological determinants of PA across the life course, by pooling the results of the available systematic literature reviews (SLRs) and meta-analyses (MAs). Methods We conducted an online search on MEDLINE, ISI Web of Science, Scopus, and SPORTDiscus databases up to January 2018. SLRs and MAs of observational studies that investigated the association between biological determinants of PA and having PA as outcome were considered eligible. The extracted …

Aaron Clevenger, Assistant Provost, Dean of International Programs, and Senior International Officer at Embry-Riddle Aeronautical University, has worked within higher education for 17 years. After a mudslide accident where student and faculty travelers may have been nearby, the President of the university called Clevenger's office to find out traveler locations. Not having the ability to answer his questions, Clevenger wanted to ensure that in the future, he had a better answer than "I don't know." Through conversations with other experts in the field, Clevenger discovered there were few comprehensive sources available with advice on how to author a travel policy. …

Extant research indicates that there continues to be a gap between employer expectations and the oral presentation skills of B-school graduate students. In order to address this gap, the authors undertook a three-year effort to research, develop, and administer a public speaking workshop focused on preparing new business graduate students to meet industry demands for presentation skills and strategies. Survey and focus group data informed several revisions to the workshop plan. The series of revisions and participant responses point toward the importance of adjusting the elements of the rhetorical situation in order to account for the principles of andragogy when …

Narcissism And Social Media Usage: Is There No Longer A Relationship?, Christina M. Frederick, Tianxin Zhang
Publications
In previous studies, narcissism has been found to relate to social media behaviors, such as how often one posts and how many friends or followers one has (McCain & Campbell, 2016; Singh, Farley, and Donahue, 2018). The present study attempted to create a model of social media use predicted by narcissism and selfconsciousness. A sample of 397 adults with a mean age of 29 years was collected using MTurk. Participants completed a social media use survey, the Narcissistic Personality Inventory (Raskin & Hall, 1979) and the Self-Consciousness Scale (Scheier & Carver, 1985). Results showed that while narcissism and selfconsciousness were …

At first glance, scientific laboratory experiences might appear to be challenging to move to the cloud. Skeptics may point to sensory feedback limitations and inequivalence of student outcomes. However, emerging data increasingly provide evidence that scientific laboratory courses are not only amenable to online learning, but also can deliver student outcomes at or above traditional in-person courses. In identifying a science lab format, each institution weighs factors like lab course goals, budget, program growth, access, and safety. This article presents a single case study and a decision matrix for how one institution informed their choice for the modality of a …

A Design Of A Material Assembly In Space-Time Generating And Storing Energy, Mihhail Berezovski, Stan Elektrov, Konstantin Lurie
Publications
The paper introduces a theoretical background of the mechanism of electromagnetic energy and power accumulation and its focusing in narrow pulses travelling along a transmission line with material parameters variable in 1D-space and time. This mechanism may be implemented due to a special material geometry- a distribution of two different dielectrics in a spatio-temporal checkerboard. We concentrate on the practically reasonable means to bring this mechanism into action in a device that may work both as energy generator and energy storage. The basic ideas discussed below appear to be fairly general; we have chosen their electromagnetic implementation as an excellent …

Developmental Aspects Of Capacities, Karen Bartsch
Animal Sentience
Chapman & Huffman suggest that judgments of human superiority underlie our cruelty to animals. It might be useful to examine how such judgments operate within the human community. Children arguably have a potential for developing “superior” capacities but are outperformed on many tasks by animals. There is a continuum of development in children’s capacities. Perhaps there are interspecies evolutionary continua too. This highlights the complexity of reasoning about humans, animals, and moral inclusion.
Humans Are Superior — By Human Standards, Susana Monsó
Humans Are Superior — By Human Standards, Susana Monsó
Animal Sentience
Chapman & Huffman argue that humans are neither unique nor superior to other animals. I believe they are right in claiming that we are no more unique than any other species, but wrong in assuming that this means we cannot be ranked as superior. I show how this need not undermine the central aim of their target article, for superiority can only be measured with respect to a certain standard, and it’s only by using anthropocentric standards that we can be plausibly regarded as superior. Other — perhaps more neutral — standards yield different results.
