The Supreme Court’s Dobbs v. Jackson Women’s Health Organization decision, first leaked to the public on 2 May 2022 and officially released on 24 June 2022, overturned Roe v. Wade and thereby determined that abortion is no longer a federally protected right under the Constitution. Instead, the decision gives individual states the right to regulate abortion. Since the Dobbs decision first leaked, our institution has received numerous requests for permanent contraception from individuals stating that their motivation to pursue permanent contraception (...) was influenced by the Dobbs decision and concerns about their reproductive autonomy. Discussions with patients seeking permanent contraception since the Supreme Court’s leaked decision have led us to ask ourselves, is legislative anxiety an indication for surgery? This article presents a case series consisting of a convenience sample of 17 young, nulliparous individuals who sought out permanent contraception in the six months following the leak of the Dobbs decision. Healthcare professionals often feel discomfort in offering permanent contraception to young and nulliparous individuals. Accordingly, we discuss pertinent legal issues, review relevant ethical considerations, and offer a framework for these discussions intended to empower the consulting healthcare professional to center the bodily autonomy of every patient regardless of age, parity, or indication for permanent contraception.

Phoebe Waller-Bridge is not an unknown name. The writer, actor, and producer has been a part of various comedy TV series and films. However, she has a pattern in her comedy writing and character creation that is obvious in the TV series – Fleabag (2016–2019) and Crashing (2016). In both these series, one cannot miss the obvious similarity between the characters she wrote and played – characters who knew what they wanted and did not hesitate to make attempts to achieve (...) it, even when it meant defying the conventional rules of social relationships and breaking out of the gender identities set by society for women. In fact, other characters created around these female characters seem to lack the same courage, which leads to the creation of comical situations but also often results in these characters facing emotional obstacles that they eventually overcome. The women in both shows not only choose to reject predefined gender identities, but also make choices and take risks while being aware of the consequences. Throughout their journeys of embracing their free consciousnesses, these characters illustrate Jean Paul Sartre’s and Simone de Beauvoir’s process of transcending their facticity, thus avoiding bad faith. Implicit in Waller-Bridge’s work is the argument that we could do better to be – and encourage other women to be – the types of women that her protagonists are. (shrink)

The current paper offers a unique perspective of looking at oblique effects in cognition, language and aesthetics in a language where geometrical horizontal and vertical orientations are not considered cardinal and primary in nature. These oblique effects are termed as atypical in nature, offering a contrast to the other languages. In this attempt, a holistic framework is provided that is couched in terms of a single theory and explains effects from two separate fields in a similar manner. The proposed holistic (...) framework provides special place for the influence of language on cognition (?class-3? theory). The paper closes with directions for future research that could potentially work towards providing further empirical evidence for strengthening the framework. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Time Together and Time ApartNeha Choksi (bio)The drawings to scale on the following pages depict multiple views I outlined while holding in my hand a single, small particolored stone. The silhouette leaves a hole for the stone to inhabit, were it still to exist. The colored pigment that shapes the absence of the stone is made by pulverizing this same stone.I pushed the pigment aside on the recto to (...) create the evacuated silhouette. Imagining the hole bored through to the other side, I colored the verso, too. All the pigment from the stone was used up in painting these multiple views.________The Crete Senesi area in Tuscany, where I found the stone, is formed from tiny fragments of small shells and sea organisms compacted with sediments of clays and sands from a sea that covered it millions of years ago. I fancy the stone contains evidence of the missing sea.I dislocated this stone during one of my multiple walks on a local strada bianchi near my temporary residence in a tiny village in Tuscany. I shared a summer there with six other artists and the coordinator as part of the Amant Residency Siena. I painted one stone view per member of our group.

Working from home (WFH) is a new reality and norm in today’s work culture. COVID-induced lockdown introduced the concept of WFH for many people. Blurring home and workplace boundaries was a prominent cause of disorientation in people’s lives. Hence, WFH becomes a significant phenomenon to explore as it raises the fundamental question of body and space in shaping people’s experiences. To study this, the researchers designed a phenomenological inquiry and examined the lived phenomenon of WFH during the COVID lockdown. Borrowing (...) theoretical concepts from philosophers Martin Heidegger and Merleau-Ponty, they aimed to understand human experiences from an embodied perspective. They interviewed a few adults (age group 27–50) in three urban Indian cities during the first phase of the COVID-19 lockdown. The participants’ experiences were transcribed, and Interpretative Phenomenological Analysis (IPA) was conducted. The IPA themes highlighted their varied lived experiences and lifeworld, such as distractions in working from home, their changed routines, habits, and social interaction. The findings are discussed through phenomenological psychology concepts such as embodied cognition, body memory, extended self, shared empathy, intersubjectivity and pre-reflective bodily intelligence in coping. The study’s contribution is that it advances a methodological understanding by interpreting people’s experiences from a phenomenological view of being-in-the-world in which the individual is not an isolated entity but is in the world/placed in the world with other people and the environment.

This study provides an innovative approach to neutrosophic algebraic structures by introducing a new structure called Neutrosophic Soft Cubic T-ideal (NSCTID), which combines T-ideal (TID) and neutrosophic Soft Cubic Sets (NSCSs) within the framework of PS-Algebra. Within the already-existing neutrosophic cubic structures, the addition of soft sets with the characteristics of TID makes this structure more desirable. The theoretical development of the proposed structure includes the application of fundamental ideas as union, intersection, the Cartesian product, and homomorphism. We also introduce (...) the notions of NSCTID-translation and NSCTID-multiplication to further enhance the structure of NSCTID. By applying the idea of translation and multiplication, we offer improved algorithm for neutrosophic cubic sets to deal with different parameters that are satisying the TID’s distinctive characteristics. Through this thorough research, we offer an elementary understanding of NSCTID and its capabilities, providing the way to new algebraic structures. (shrink)

We usually think nothing of our practice of ‘giving up’ on someone who has behaviors or attitudes that are morally criticizable—after all, it is my prerogative to choose with whom I will associate, and exclusion seems to be an unobjectionable part of my toolkit of social sanctions. However, this paper will argue that it is in many cases impermissible to give up on a morally unpleasant person—in fact, it would be to make an unjustified exception for oneself.

An individual’s accountability to oneself leads to self-regulatory behaviour. A field experiment afforded an opportunity to test this relation, given that external accountability conditions were absent. A single group pre-test/post-test design was used to test the hypothesis. A group of full-time resident management students, n ≈ 550, take four meals during the day in the institute mess. As a part of the experiment, food wastage in the form of leftovers on the plates of subjects was measured. As a pre-test, the (...) measurement occurred at two levels. Subjects could see how much they are adding to the total waste by looking at a weighing scale placed under a waste basket, and they could also see the total waste data for each of the four meals for the day and a day earlier displayed at a prominent place. After 105 days, the weighing scale under the basket was removed, and as a post-test measurement, the total waste data for the four meals were noted down for another 72 days. A manipulation test indicated that the experiment has had the desired effect of invoking self-accountability in subjects during the pre-test phase, and diluting it during the post-test phase. Time series analysis of pre-test and post-test data indicated that the wastage data decreased in the pre-test phase. However, the post-test waste data showed an increase over a period of time. The results indicate that accountability conditions like social norms invoke self-accountability cognition leading to self-regulatory behaviours in individuals. (shrink)

Schematic, propositional, analogical and associative representational Systems (SPAARS) is the integrated cognitive model of emotion proposed by Power and Dalgleish (Cognition and Emotion: from order to disorder. The Psychology Press, England, 1997). It is multi-level in nature and includes four different levels of representation. In SPAARS, emotions are described as appraisal-based according to an individual’s goals, thus making the theory functional in nature. Basic emotions possess an innate component and hence can be elicited automatically, since these emotions might already have (...) been appraised in an individual’s evolutionary past. Thus, the theory proposes two routes for the generation of emotions. It provides an useful approach within which both basic and complex emotions can readily be understood. The theory can also be applied in order to explain emotional disorders as well as to generate novel therapeutic interventions for them. In the current review the SPAARS approach has been used to understand psychopathy, also called the disorder of empathy (a complex emotion). The theory provides a new perspective for looking at psychopaths. It suggests that psychopathy may arise either due to a problem generating the basic emotion of sadness, the complex emotion of empathy or a combination of the two. The interventions suggested would also vary depending upon the underlying nature of the problem. (shrink)

Classifying spatial frames of references have placed egocentric/body-based representations on muddy grounds. The traditional taxonomy places it under the deictic distinction while the Levinson’s terminology does not provide a special status for it but classifies it along with the relative frame of reference. Research from other areas of cognition has come up with other implied classifications that are motivated by the special role played by these egocentric representation(s). Tangled among such issues is the fuzzy distinction between egocentric and body based (...) representations. The current paper takes up exactly this issue and proposes to sub classify egocentric representations into two different subtypes namely the first- and the second-order representations. The proposed distinction serves an essential purpose for understanding important cognitive processes like spatial transformation, mental perspective taking, and so on. (shrink)

Many kinds of multifunctional regulatory proteins have been identified that perform distinct biochemical functions in the nucleus, the cytoplasm, or both. Here we describe the recent discovery by Hall et al. (2004)1 of a new type of multifunctional protein: a metabolic enzyme that doubles as a transcription factor. This enzyme, Arg5,6, functions as a catalytic enzyme in ornithine biosynthesis and also binds and regulates the promoters of nuclear and mitochondrial genes. It may also regulate precursor mRNA metabolism. We discuss how (...) proteins that serve as both metabolic enzymes and transcription factors might have evolved.

Imbalance in the pH of water reduces this precious resource as an extremely dangerous liquid for human health and plants’ growth. Change in the pH levels of the drinkable water has majorly raised concern towards diverse health issues like heart problems, infant mortality rates, pigmentation of skin, and cholera outbreaks. Therefore, it is necessary to keep a check on essential water quality components that include acidic/basic nature of water. As per the US Environmental Protection Agency, the drinkable water should have (...) a pH level ranging from 6.5 to 8.5. Two sample situates have been identified wherever highly reported pollutants levels were found and have been analyzed through artificial intelligence techniques. It can be observed that wavelet denoised signals fed into the least squares support vector regression and M5 prime regression tree predicted more accurately on the basis of the performance errors that are as follows: root mean squared error ; mean squared error ; mean absolute error. On the basis of these errors, the coefficient of determination/goodness of fit simulated for the prototypes is developed in this study. RMSE outcomes diminish on the whole on applying the training and forecasting data-division via WLSSVR and WM5pRT as compared with fitting the normalized data through LSSVR and M5pRT. These performance measures are essential to analyze the concentration levels of pH in the river streams at the identified sites of study. Thus, the observed pattern from this study may help for future estimation of the quality of water at their sources so that it prohibits the further increase in either acidic or basic salts which prove to be lethal for the environment. Thus, these predictors would be helpful towards formulation of strategies for protection of ecosystem and human health. (shrink)

It is now a well-documented statistic that Asian women between the ages of 15–35 are two to three times more vulnerable to suicide and self-harm than their non-Asian counterparts (Soni-Raleigh, 1996). The article will summarize the findings of the research report Growing Up Young, Asian and Female in Britain (Newham Asian Women's Project, 1998), which aimed to explore the reasons why young Asian women self-harmed and to evaluate the service responses they were given. It also made recommendations aimed at decreasing (...) the high prevalence of suicide and self-harm among young Asian women. The article concludes by reflecting upon the impact and service developments that have been made since the report was published. (shrink)

We consider the structures $$, $$, $$, and $$ where $\mathbb {Z}$ is the additive group of integers, $\mathrm {SF}^{\mathbb {Z}}$ is the set of $a \in \mathbb {Z}$ such that $v_{p} < 2$ for every prime p and corresponding p-adic valuation $v_{p}$, $\mathbb {Q}$ and $\mathrm {SF}^{\mathbb {Q}}$ are defined likewise for rational numbers, and $<$ denotes the natural ordering on each of these domains. We prove that the second structure is model-theoretically wild while the other three structures are (...) model-theoretically tame. Moreover, all these results can be seen as examples where number-theoretic randomness yields model-theoretic consequences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:preface At a time when access to safe abortions is being curtailed in the United States under the pretext of a response to the COVID-19 pandemic, this Feminist Studies issue focuses on abortion and women’s embodiment. The essays by Melissa Oliver-Powell, Rachel Alpha Johnston Hurst, and Jennifer L. Holland each contribute new approaches to the stillvexed topic of abortion, positioning movements for abortion access in relation to historical and (...) ecological change. Two collaboratively written essays, by South American authors María Fernanda Olarte-Sierra and Tania Pérez-Bustos, and by North American and European authors Laura Bisaillon with six colleagues, both center the body within feminist labor, exploring how the embodied experience of work can also be a site of knowledge-making. Other authors push us to move beyond humanistic understandings of affect and the body in feminist work, as Nathan Snaza shows in a review essay of four recent books engaging “Biopolitics without Bodies.” Poems by Rosetta Marantz Cohen, Darlene Taylor, and Abby Minor also feature experiences of bodily violence and bodily pleasure, while Ellyn Weiss discusses the distinctive representations of bodies in the visual art of Swedish-American artist Anna U. Davis. To close the issue, two News and Views pieces by Pang Laikwan and Sealing Cheng on the recent protest movement in Hong Kong provide two complementary perspectives on living through tumultuous political times. Our next issue will include content directly focused on the COVID-19 pandemic. In the first essay, Melissa Oliver-Powell’s “Beyond the Spectacle of Suffering: Agnès Varda’s L’Une chante, l’autre pas and Rewriting the Subject of Abortion in France” addresses the complexities of anti-​ abortion 8 rhetoric in France. Placing Varda’s 1977 film in the historical context of French nationalistic anxiety about low birthrates in the twentieth century, Oliver-Powell argues that the film deconstructs polarized narratives about abortion. While dominant cultural representations of abortion typically depicted it as the result of female irresponsibility or traumatic victimization, Varda’s film rejects the binary concepts of villain and victim and questions the presumption that women always suffer when exercising their reproductive choice. Oliver-Powell situates Varda alongside the 343 eminent French female cultural leaders who composed a famous 1971 Manifesto publicly declaring themselves criminals for having had illegal abortions and presents simultaneous histories of French feminism and French cinema. Varda’s film constructs a feminist representation of abortion that avoids foregrounding women ’s suffering and instead emphasizes empowerment and solidarity. Its narrative features two women friends, both treated unjustly by France’s abortion laws, who participate in the movement for reform over a fourteen -year span. Varda represents the interplay of motherhood with women ’s lives as a continuum, not a disruptive episode, and she blends documentary -style devices with imaginative musical interludes: she shows actual women seeking abortions in Holland and includes songs about abortion, pregnancy, and motherhood. Oliver-Powell claims that Varda dramatizes unprecedented representations “of female friendship without pathology, of abortion without guilt, death or persecution, of motherhood without objectification....” A second essay, Rachel Hurst’s “Abortion as a Feminist Pedagogy of Grief in Marianne Apostolides’s Deep Salt Water,” proposes that the championing of women’s reproductive rights could better account for the context of difficult emotions and an imperfect world. Hurst uses reproductive justice approaches to critique simplistic rights-based arguments for abortion, premised on liberal concepts of choice and autonomy, which fail to understand the material conditions of poor women and especially women of color. Such analyses emphasize the necessity of rights discourses that include the right to bear and parent one’s own children free from violence and economic hardship, and they advocate the transformative possibilities of acknowledging rather than suppressing women’s ambivalence about their own abortions as well as others’ choices. Hurst describes a collaboration between two contemporary Canadian feminists, writer Marianne Apostolides and visual artist  9 Catherine Mellinger, in their mixed-media text, Deep Salt Water, which is organized according to the weeks of a pregnancy and the aftermath of its termination. Rather than falling back into familiar polarizations for and against “choice,” they use the story of Apostolides’s abortion seventeen years earlier... (shrink)

In Cognitive Gadgets, Heyes seeks to unite evolutionary psychology with cultural evolutionary theory. Although we applaud this unifying effort, we find it falls short of considering how culture itself evolves to produce indigenous psychologies fitted to particular environments. We focus on mentalizing and autobiographical memory as examples of how socialization practices embedded within culture build cognitive adaptations.

BackgroundChildhood abuse increases risk for high levels of distress in response to future stressors. Interpersonal social support is protective for health, particularly during stress, and may be particularly beneficial for individuals who experienced childhood abuse.ObjectiveInvestigate whether childhood abuse predicts levels of posttraumatic stress disorder (PTSD) symptoms related to the COVID-19 pandemic, and test whether the perceived availability of social companionship preceding the pandemic moderates this relationship.MethodsDuring Phase 1, adults (N= 120; AgeM[SD] = 19.4 [0.94]) completed a retrospective measure of childhood (...) adversity along with a measure of perceived availability of opportunities for social engagement immediately preceding the pandemic. Two weeks after the COVID-19 pandemic declaration, participants completed the Impact of Event Scale-Revised (IES-R) with respect to the pandemic. Hierarchical linear regression analyses examined the interaction between childhood abuse and the perceived availability of social companionship preceding the pandemic as a predictor of PTSD symptoms.ResultsAdjusting for covariates, the interaction between childhood abuse and perceived availability of others to engage with before the onset of the pandemic was a significant predictor of IES-hyperarousal (β = −0.19,t= −2.06,p= 0.04, ΔR2= 0.032, CI: [−0.31 to −0.01]).ConclusionLevels of perceived opportunities for social companionship before the pandemic associates with levels of hyperarousal related to the pandemic, particularly for individuals who experienced high levels of childhood abuse. More research is needed to understand how to mitigate the higher levels of distress related to the pandemic for these individuals in order to reduce risk for future psychiatric disorders. (shrink)

Research represents an avenue through which patients can contribute to the knowledge base surrounding their condition. However, persons with dementia cannot legally consent to participation in most scientific research. One possible avenue to preserve patient autonomy in the sphere of research is through an advance planning document. Scholars of medicine, ethics, and law have largely approached this topic from a theoretical angle, compelling the authors to develop and implement a tangible research-specific advance planning tool. In order to inform the creation (...) of this novel legal instrument, the present study leveraged semistructured telephone interviews with cognitively intact older adults in the Upper Connecticut River Valley region of New Hampshire. Participants were prompted to reflect on their attitudes toward participation in scientific research, should they develop dementia. They were also asked to consider the possibility of incorporating research into their advance planning regime, their preferred format for a research-specific advance planning tool, and the potential relationship between an advance planning tool and their surrogate decision maker in the context of research participation. Qualitative analysis was employed to extract themes from interview responses, revealing a pervasive desire for an advance planning tool that embraces specificity, flexibility, practicality, and the integral role of the surrogate decision maker. Ultimately, through collaboration with physicians and an elder law attorney in the region, these findings were translated into a research-specific advance planning component within the Dartmouth Dementia Directive.

A bewildering range of games are emerging every other day with newer elements of fun and entertainment to woo youngsters. Games are meant to reduce stress and enhance the cognitive development of children as well as adults. Teenagers are always curious to indulge in newer games; and e-gaming is one such platform providing an easy access and quicker means of entertainment. The particular game challenge which has taken the world by storm is the dangerous “Blue Whale Challenge” often involving vulnerable (...) teenagers. The Blue Whale Challenge is neither an application nor internet based game but the users get a link through social media chat groups to enter this “deadly” challenge game. This probably is the only game where the participant has to end his/her life to complete the game. The innocent teenagers are being targeted based on their depressed psychology and are coercively isolated from their social milieux on the pretext of keeping the challenges confidential. To add to the woes, no option is offered to quit the challenge even if the contender is unable to complete the challenge. Blue Whale Challenge in its sheer form could be seen as an illegal, unethical and inhumane endeavor in our present society. The present communication discusses the severe effects of the game on teenagers, the ethical concerns involved and the preventive measures necessary to curb it. (shrink)

Prior research in judgment and decision making (JDM) has investigated the effect of problem framing on human preferences. Furthermore, research in JDM documented the absence of such reversal of preferences when making decisions from experience. However, little is known about the effect of context on preferences under the combined influence of problem framing and problem format. Also, little is known about how cognitive models would account for human choices in different problem frames and types (general/specific) in the experience format. One (...) of the primary objectives of this research is to investigate the presence of preference reversals under the influence of problem framing (gain/loss), problem format (experience/description), and problem type (general/specific). Another objective of this research is to develop cognitive models to account for human choices across different problem frames and types in the experience format. A total of 320 participants from India were randomly assigned to one of eight between-subjects conditions that differed in problem frame, format, and type. Results revealed preference reversals in the description condition; however, they were absent in the experience condition. Moreover, preference reversals were less pronounced in the general problem framing compared to the specific problem framing. Furthermore, specific problems influenced risk-seeking behavior among participants. We developed cognitive and heuristics models using instance-based learning theory and natural mean heuristic. Results reveal models’ dependency on recent and frequent observations during information sampling. These experience-based cognitive models could help build artificial intelligence models with fewer preference reversals. (shrink)

The current paper argues for synchronising spatial frames of reference for achieving effective multiparty communication in collaborative virtual environments. Synchronising nonverbal behaviour from different modalities is an important step for simulating face-to-face-interaction where all nonverbal cues are available. Such synchronisation also serves as an effective basis for building multimodal interfaces especially if these have to be deployed for multiparty communication. It is argued that common spatial reference frames are helpful in coordinating different points of attention and facilitating work by serving (...) as the springboard for joint attention among members of the team. Consequently, it is desirable to aim for such common grounds and not just focus on coordinating disjointed virtual spaces for facilitating decision-making by reducing felt collaborative effort. Implementing the synchronisation of spatial reference frames for modern technologies thus serves dual purposes by achieving common grounds in communication and maintaining autonomy of each member at the same time. Towards this end, the current paper proposes the concept of decentred egocentric frame, the origin of which is one’s own body and the spatial relation between two objects is defined with respect to this origin. This frame seems to be important for separating each member’s focus from his own body (self/activities) and also helps in coordinating one’s focus with those of the others whether interacting verbally or nonverbally. This is an important conceptual development as the proposed classification is hypothesised to function in a similar manner across different sensory modalities. The paper concludes with issues on implementation and other future conceptual developments. (shrink)

The paper considers two-agent order acceptance scheduling problems with different scheduling criteria. Two agents have a set of jobs to be processed by a single machine. The processing time and due date of each job are known in advance. In the order accepting scheduling problem, jobs are allowed to be rejected. The objective of the problem is to maximize the net revenue while keeping the weighted number of tardy jobs for the second agent within a predetermined value. A mixed-integer linear (...) programming formulation is provided to obtain the optimal solution. The problem is considered as an NP-hard problem. Therefore, MILP can be used to solve small problem instances optimally. To solve the problem instances with realistic size, heuristic and metaheuristic algorithms have been proposed. A heuristic method is used to determine and secure a quick solution while the metaheuristic based on particle swarm optimization is designed to obtain the near-optimal solution. A numerical experiment is piloted and conducted on the benchmark instances that could be obtained from the literature. The performances of the proposed algorithms are tested through numerical experiments. The proposed PSO can obtain the solution within 0.1% of the optimal solution for problem instances up to 60 jobs. The performance of the proposed PSO is found to be significantly better than the performance of the heuristic. (shrink)

Sitting on the fine line between pathogen ‘transmissibility’ and ‘severity’, the Behavioural Immune System (BIS) is responsible for activating behaviours that minimise infection risks and maximise fitness. To achieve self-preservation, the BIS also fuels social and political attitudes. We aim to explain societal changes that may be sparked by COVID-19 by highlighting links between human evolutionary history and our psychological faculties mediated by the BIS.
