We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

In a fictional conversation designed to appeal to both working teachers and social philosophers, three educators take up the question of whether critical thinking itself can, or should, be taught independently of an explicit consideration of issues related to social justice. One, a thoughtful but somewhat traditional Enlightenment rationalist, sees critical thinking as a neutral set of skills and dispositions, essentially unrelated to the conclusions of morality, problems of social organization, or the content of any particular academic discipline. A second (...) interlocutor, steeped in “critical” pedagogy of Paulo Freire, insists that the problem is the pose of neutrality itself. On this view, all honest and effective approaches to teaching must confront the hegemony of unjust relationships, institutions, and conceptual schemes. The third character attempts to resolve the tension between these two opposed camps. (shrink)

This dialogue discusses a proposal for the legalization of torture under specific circumstances and contrasts it with arguments for a total ban on torture. We consider three types of objection: first, that the difficulty of having adequate knowledge renders the stock “ticking bomb” scenario such a low-probability hypothetical as to present no realistic threat to a policy banning all torture; second, that empirically the information gleaned from torture is so unlikely to be reliable that it could not justify the moral (...) risk; and third, that sanctioning torture, even if only under the most extreme circumstances, would generate a ‘culture of torture,’ hence undermining fragile advances in international human rights rooted in unwavering commitment to human dignity. Compelling as these arguments appear, not all the conversants are wholly convinced by them; to this extent the dialogue ends aporetically. (shrink)

This article presents a critique of an article previously featured in Nursing Philosophy (10: 26–33) by Ursula Naue and Thilo Kroll, who suggested that people living with dementia are assigned a negative status upon receipt of a diagnosis, holding the identity of the ‘demented other’. Specifically, in this critique, we suggest that unwitting use of the adjective ‘demented’ to define a person living with the condition is ill-informed and runs a risk of defining people through negative (self-)attributes, which has a (...) deleterious impact upon that person's social and relational personae. Moreover, use of the locution ‘demented’ reinforces a divide between the ‘demented’ (them) and the ‘healthy others’ (us). Social constructionist theory, malignant positioning and viewing people with dementia as semiotic subjects are the philosophical pillars through which we construct the main arguments of the critique. The article concludes with the voice of one of the authors, a younger person with dementia, asking for language in dementia care to be carefully reconsidered and reframed and for the recognition of the diagnosed person's agency in the conduct of their day-to-day lives.

From certain sorts of premise, individuals reliably infer invalid conclusions. Two Experiments investigated a possible cause for these illusory inference: Reasoners fail to think about what is false. In Experiment 1, 24 undergraduates drew illusory and control inferences from premises based on exclusive disjunctions (“or else”). In one block, participants were instructed to falsify the premises of each illusory and control inference before making the inference. In the other block, participants did not receive these instructions. There were more correct answers (...) for illusory disjunctions whose premises had been falsified than there were for illusory disjunctions that had not been falsified. A second Experiment introduced illusory inferences in a real world context that accentuated falsification of premises. Accuracy also improved. Knowledge of how to falsify premises and to consider their implications for true premises transferred to a new problem introduced at the end of the Experiment without the falsification instruction. The participants' ratings of the difficulty of the inferences showed that they did not err simply because illusory inferences are perceived to be more difficult than control problems. The model theory predicts these results because it postulates that the limitations of working memory preclude the representation of false information. (shrink)

We refine the constructions of Ferrante-Rackoff and Solovay on iterated definitions in first-order logic and their expressibility with polynomial size formulas. These constructions introduce additional quantifiers; however, we show that these extra quantifiers range over only finite sets and can be eliminated. We prove optimal upper and lower bounds on the quantifier complexity of polynomial size formulas obtained from the iterated definitions. In the quantifier-free case and in the case of purely existential or universal quantifiers, we show that Ω quantifiers (...) are necessary and sufficient. The last lower bounds are obtained with the aid of the Yao-Håstad switching lemma. (shrink)

It is important to understandfactors that influence management decisionsthat determine the level of diversificationwithin cropping systems. Because of the widevariety of cropping systems within a region,our study focused on a single county in northwestern Minnesota. This county wasselected because it is in an area where farmerswere reevaluating their cropping practicesduring the 1990s in response to severe plantdisease outbreaks and economic stresses. Asurvey and follow-up interviews of representative farmers in Marshall Countyshowed that they were approaching theircropping systems management decisions underthese conditions (...) through a dominant conceptualframework and two secondaryconceptual frameworks, which we termed “mental causalmodels.” The study illustrates the ways farmersdefine and make decisions affecting theircropping systems diversity under conditions ofagronomic and economic adversity. It alsochallenges agricultural professionals to expandtheir thinking about educational strategiesthat are sensitive to the varied perspectivesof farmers beyond just the scientific mentalcausal model.

Working parents in are struggling to balance the demands of their occupation with those of childcare and homeschooling during the COVID-19 pandemic. Moreover, studies show that women are shouldering more of the burden and reporting greater levels of psychological distress, anxiety, and depression relative to men. However, research has yet to show that increases in psychological symptoms are linked to changes in stress during the pandemic. Herein, we conduct a small-N study to explore the associations between stress and psychological symptoms (...) during the pandemic among mothers using structural equation modeling, namely latent change score models. Thirty-three mothers completed questionnaires reporting current anxious and depressive symptoms, as well as stressful life experiences prior to-versus during the pandemic. Women endorsed significantly more stressful events during the pandemic, relative to the pre-pandemic period. Additionally, 58% of mothers scored as moderate-to-high risk for developing a stress-related physical illness in the near future because of their pandemic-level stress. Depressive symptoms were associated with the degree of change in life stress, whereas anxiety symptoms were more related to pre-pandemic levels of stress. The present study preliminarily sheds light on the nuanced antecedents to mothers’ experiences of anxious and depressive symptoms during the COVID-19 pandemic. Although further work is needed in larger, more diverse samples of mothers, this study highlights the potential need for appropriate policies, and prevention and intervention programs to ameliorate the effects of pandemics on mothers’ mental health.

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices, particularly choices that entail seeking of certain drugs or behaviors. We identify 10 key vulnerabilities in the system: (1) moving away from homeostasis, (2) (...) changing allostatic set points, (3) euphorigenic signals, (4) overvaluation in the planning system, (5) incorrect search of situation-action-outcome relationships, (6) misclassification of situations, (7) overvaluation in the habit system, (8) a mismatch in the balance of the two decision systems, (9) over-fast discounting processes, and (10) changed learning rates. These vulnerabilities provide a taxonomy of potential problems with decision-making systems. Although each vulnerability can drive an agent to return to the addictive choice, each vulnerability also implies a characteristic symptomology. Different drugs, different behaviors, and different individuals are likely to access different vulnerabilities. This has implications for an individual's susceptibility to addiction and the transition to addiction, for the potential for relapse, and for the potential for treatment. (shrink)

The debate on the value of Boyer's minimally counter-intuitive theory continues to generate considerable theoretical and empirical attention. Although the theory offers an explanation as to why certain cultural texts and narratives are particularly well conveyed and transmitted, amidst society and over time, conflicting evidence remains for any mnemonic advantage of minimally counter-intuitive concepts. In an effort to reconcile these conflicting results, Barrett has made a comprehensive attempt in presenting a formal system for quantifying counter – intuitiveness including a distinction (...) between counter-intuitive and counter-schematic concepts. The present article uses this system to generate sentences containing different levels of counter-intuitiveness, and tests whether minimally counter-intuitive items show a mnemonic advantage over concepts which are more counter-intuitive or counter-schematic. Results indicate that MCI concepts hold a mnemonic advantage over counter-schematic and maximally counter-intuitive concepts but only for one-week delayed recall. Interference effects may have masked immediate recall effects. Yes-no recognition after one week delay showed almost 100% accuracy suggesting that availability of retrieval cues is the factor which determines the mnemonic advantage of MCI concepts. (shrink)

Drawing on sixty-one in-depth interviews conducted with commercial and noncommercial scientists at four universities in the United States, this paper examines why academic scientists embrace commercially oriented career paths in higher education. A central goal of this paper is to expand our descriptive and conceptual understanding of socialization in the academic profession by examining the explanatory power of differential association theory. Differential association theory emphasizes how patterns of behavior are learned through a process of interaction with different types of individuals (...) with varying ideas about the acceptability of a particular course of action. The results demonstrate that socialization to commercialism is an interactive learning process in which scientists learn definitions that are favorable to commercial career trajectories. Such learning is often necessary because prior socialization can either lead to unfavorable views of commercialization or shelter doctoral students from techniques of and rationales for commercialization.

Since Einstein’s failure to define a Grand Unified Theory, physicists have pursued a comprehensive theory explaining nature, a Theory of Everything. But because General Relativity, Quantum Field Theory, and Cosmology have little in common, defining one theory is an imposing task, having eluded the best scientists for ninety years. So are we close to defining a Theory of Everything? This analysis, after defining requirements, identifies four possible options for a Theory of Everything. Quotes from prominent physicists express divergent views on (...) each alternative.The leading proposal for a Theory of Everything is String Theory, which has possible issues. It requires supersymmetry, has extra compacted dimensions, and is background-dependent. A second less comprehensive theory is Loop Quantum Gravity, which emphases background-independence based on discrete quantum space. Explaining how theories define relationships between spacetime, quantum space, quantum time, and quantum gravity, positions the role of background-independence in proposed theories. If supersymmetry and extra dimensions are discovered, String Theory or a modified String Theory integrated with Loop Quantum Gravity, may be the option. Or, possibly a radically new theory might be developed. Or, as the last option considers, the answer to the question — Does a Theory of Everything exist? — may be no; if so, nature will always be a mystery. (shrink)

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)
