Presentists argue that only the present is real. In this paper, I ask what duration the present has on a presentist’s account. While several answers are available, each of them requires the adoption of a measure and, with that adoption, additional work must be done to define the present. Whether presentists conclude that a reductionist account of duration is acceptable, that duration is not an applicable concept for their notion of the present, that the present has a duration of zero, (...) or that that the present has a duration, a more robust account of the present is required. I suggest that some of the most difficult questions about duration can be avoided at the cost of no longer viewing presentism as a theory about time, but rather as a theory about existence. In the conclusion, I suggest an interpretation of presentism that allows it to endorse the view that time is nothing more than the measure of change. (shrink)

Psychology's tendency to focus on confirmatory analyses before ensuring constructs are clearly defined and accurately measured is exacerbating the generalizability crisis. Our growing use of digital behaviors as predictors has revealed the fragility of subjective measures and the latent constructs they scaffold. However, new technologies can provide opportunities to improve conceptualizations, theories, and measurement practices.

Ethical issues in biomedical research are traditionally examined as distinct from those of clinical care. However, this traditional framing may obscure questions of equity and fairness in both rese...

Sex steroids, through their receptors, have potent effects on the signal pathways involved in osteogenic or myogenic differentiation. However, a considerable segment of those signal pathways has a prominent role in epithelial neoplastic transformation. The capability to intervene locally has focused on specific ligands for the receptors. Nevertheless, many signals are mapped to interactions of steroid receptor motifs with heterologous regulatory proteins. Some of those proteins interact with the glucocorticoid receptor and other factors essential to cell fate. Interactions of steroid (...) receptor domain motifs with heterologous proteins affect specific target pathways; consequently, manipulation of specified protein modules complexed with steroid receptors may be a next major step for enhancing molecular targeted therapeutics. In the future, intervention at specific sections of receptor primary sequence may prove therapeutically more efficient in targeting pathways of choice than ligand selectivity can be. (shrink)

We bear witness to a sweeping social movement for change—fostered and driven by a powerful group of Black nurses and nursing students determined to call out and dismantle anti‐Black racism and discrimination within the profession of nursing. The Black Nurses Task Force, launched by the Registered Nurses' Association of Ontario (RNAO) in July 2020, is building momentum for long‐standing change in the profession by critically examining the racist and discriminatory history of nursing, listening to and learning from the lived experiences (...) of the Black nursing community, and shaping concrete, actionable steps to confront anti‐Black racism and discrimination in academic settings, workplaces, and nursing organizations. The Black Nurses Task Force and the RNAO are standing up and speaking out in acknowledgment of the magnitude of anti‐Black racism and discrimination that exist in our profession, health system, justice system, and economic system. This social movement is demonstrating, in actions, how individuals and a collective act as change agents to drive meaningful and widespread change for our present and future Black nurses. We also acknowledge the Black nurses who have gone before us. (shrink)

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.

Hazing behaviors as a part of group initiations have been theorized to contribute to a sense of group solidarity, to ensure loyalty and commitment of group members, to teach group-relevant skills and attitudes to group members, and to reinforce the social hierarchy within groups. In a survey of members of an international college fraternity, researchers propose and test a four-dimensional model of hazing motivation. Using exploratory factor analysis, the proposed four-factor model explains 74 percent of the overall variance and confirmatory (...) factor analysis demonstrated acceptable model fit. Correlation and regression analysis suggested that social dominance- motivated hazing is strongly associated with hazing tolerance, moral disengagement, and a variety of measures related to organizational commitment and attachment.

Through the ability to preview the future , people can anticipate how best to think, feel and act in just about any setting. But exactly what factors determine the contents of prospection? Extending research on action identification and temporal construal, here we explored how action goals and temporal distance modulate the characteristics of future previews. Participants were required to imagine travelling to Egypt to climb or photograph a pyramid. Afterwards, to probe the contents of prospection, participants provided a sketch of (...) their imaginary experience. Results elucidated the impact of goal type and temporal distance on mental imagery. While a climbing goal prompted participants to draw a larger pyramid in the near than distant future, a photographic goal influenced only the compositional complexity of the sketches. These findings reveal how action goals and temporal distance shape the contents of future simulations. (shrink)

The microbiota-gut-brain field holds huge potential for understanding behavioral development and informing effective early interventions for psychological health. To realize this potential, factors that shape the MGB axis in infancy must be integrated into a systemic framework that considers salient behavioral outcomes. This is best accomplished applying network analyses in large prospective, longitudinal investigations in humans.

We examined the relationship between leader behavioral integrity and leader behavioral courage using data from two studies. Results from Study 1, an online experiment, indicated that behavioral manifestations of leader behavioral integrity and situational adversity both have direct main effects on behavioral manifestations of leader courage. Results from Study 2, a multisource field study with practicing executives, indicated that leader behavioral courage fully mediates the effects of leader behavioral integrity on leader performance and leader executive image. Implications of these findings (...) and future directions are discussed. (shrink)

This paper examines the concept and treatment of divorce in ancient Judea as a historical reality rather than a theological issue, focusing particularly on the idea of the wife as the active party in the divorce. Did women in Judea have the right to initiate divorce? It seems the answer might have been yes. The implications of several key documentary sources, including various marriage and legal contracts relating to divorce are discussed. The paper concludes with a brief look at several (...) scriptural precedents for divorce. Both the historical merit and historiographical problems with these ancient sources are addressed. (shrink)

As one example of how modern Western societies are increasingly obliged to reconcile questions of civility and justice against common, indeed revered, practices that compromise nonhuman animals, this paper examines the recent history of public debate regarding the use of animals for public entertainment in the Canadian West. Using media-based public dialogue regarding the annual Calgary Stampede as a case study and couching the high-risk use of horses in the sociological language of “sports-related violence,” the paper explores the various arguments (...) for and against the continued use of horses at the self-proclaimed “Greatest Outdoor Show on Earth” despite unambiguous evidence of the harm that regularly, and sometimes graphically, occurs.

Science fiction is often used as a tool with which to think about actual science. While often this is depicted in terms of imaginary future potential, science fiction has also shown itself to be a poignant critique of existing science and a means of exploring our collective anxieties regarding the continued logic of current scientific development. This article explores the science fiction of organ transplantation, as mapped against scientific and medicolegal developments in actual organ transplantation. Explored through the lens of (...) Adorno’s work on cultural criticism, it is argued that science fiction serves as a tool with which we address (and critique) the ethical boundaries (and fears, often colonial in nature) of actual organ transplantation. Science fiction works such as Larry Niven’s Known Space Universe and Repo! The Genetic Opera are examined, demonstrating that in critiquing the science of organ transplantation, fictionists ultimately come to examine changing cultural understandings of selfhood and embodiment.

Throughout the twentieth and twenty-first centuries, artists and scholars have pursued connections between modern art movements and scientific exploration and expertise. Particularly in discussions of Cubism and Futurism, artists and historians have employed the terms ‘fourth dimension’, ‘simultaneity’, and ‘space-time’ in their artistic theories. Select scholars have connected the use of these terms with Albert Einstein’s theories of relativity. This paper presents brief notes on this perceived intersection between Western science and art during the early to mid-twentieth century. It focuses (...) on the Bauhaus master Laszlo Moholy-Nagy, for whom ideas of “space-time” offered new and dynamic possibilities for art and perception. Rather than solely trying to interpret or represent Einstein’s theories in art, Moholy-Nagy considered the artistic implications of a theory that challenged the notion of absolute time and space. His writing on technology and the use of projected light to produce spatial modulation greatly impacted subsequent generations of artists. Moholy-Nagy also viewed greater collaboration within the disciplines of science and art as necessary. He argued that in order to best respond to the twentieth century a new generation of artists must be equipped with both technical and scientific expertise. (shrink)

This paper explores how undergraduate students understood the social relevance of their engineering course content knowledge and drew broader social and ethical implications from that knowledge. Based on a three-year qualitative study in a junior-level engineering class, we found that students had difficulty in acknowledging the social and ethical aspects of engineering as relevant topics in their coursework. Many students considered the immediate technical usability or improved efficiency of technical innovations as the noteworthy social and ethical implications of engineering. Findings (...) suggest that highly-structured engineering programs leave little room for undergraduate students to explore the ethical dimension of engineering content knowledge and interact with other students/programs on campus to expand their “technically-minded” perspective. We discussed the issues of the “culture of disengagement” :42–72, 2014) fueled by disciplinary elitism, spatial distance, and insulated curriculum prevalent in the current structure of engineering programs. We called for more conscious effort by engineering educators to offer meaningful interdisciplinary engagement opportunities and in-class conversations on ethics that support engineering students' holistic intellectual growth and well-rounded professional ethics.

Patient RB has a peculiar memory impairment wherein he experiences his memories in rich contextual detail, but claims to not own them. His memories do not feel as if they happened to him. In this paper, I provide an explanatory model of RB’s phenomenology, the self-attentional model. I draw upon recent work in neuroscience on self-attentional processing and global workspace models of conscious recollection to show that RB has a self-attentional deficit that inhibits self-bias processes in broadcasting the contents of (...) episodic memories to the global workspace. Typically, self-related contents enjoy a higher salience level than other-related contents. Elimination of bias toward self-related contents diminishes the salience of those contents to the level of other-related contents. Because the typical high salience of self-related content is necessary for the feeling of ownership, RB lacks the feeling of ownership. I also discuss potential applications of the self-attentional model to other psychopathological cases. (shrink)

ObjectiveOverweight and obesity [body mass index ≥ 25 kg/m2] are associated with poorer prognosis among women with breast cancer, and weight gain is common during treatment. Symptoms of depression and anxiety are also highly prevalent in women with breast cancer and may be exacerbated by post-diagnosis weight gain. Altered brain function may underlie psychological distress. Thus, this secondary analysis examined the relationship between BMI, psychological health, and resting state functional connectivity among women with breast cancer.MethodsThe sample included 34 post-menopausal women (...) newly diagnosed with Stage 0-IIa breast cancer who were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. At baseline prior to randomization, whole-brain analyses were conducted to evaluate the relationship between BMI and seed-to-voxel rsFC of the hippocampus and amygdala. Connectivity values from significant clusters were then extracted and examined as predictors of self-reported depression and anxiety.ResultsMean BMI was in the obese range. For both seeds examined, higher BMI was associated with lower rsFC with regions of prefrontal cortex, including ventrolateral PFC, dorsolateral PFC, and superior frontal gyrus. Hippocampal connectivity with the vlPFC was negatively correlated with self-reported anxiety.ConclusionHigher BMI was associated with lower hippocampal and amygdala connectivity to regions of PFC implicated in cognitive control and emotion regulation. BMI-related differences in hippocampal and amygdala connectivity following a recent breast cancer diagnosis may relate to future worsening of psychological functioning during treatment and remission. Additional longitudinal research exploring this hypothesis is warranted. (shrink)

While many bibliometric techniques have been employed to represent the structure of academic research communities over the years, much of this work has been conducted on scientific fields as opposed to those in the humanities. Here we use graphing techniques to present two networks that allow us to explore the structure of a subset of the philosophy community by mapping the citations between philosophical texts on the topic of ontology (the study of what exists). We find a citation gap between (...) philosophers studying material and abstract objects, and between analytic and continental ontologists, but other predictions were not confirmed by this method. We conclude by considering several additional methods for further exploring both the structure of philosophy and other disciplines in the humanities. (shrink)

To hold that artworks are valuable for their own sake—regardless of whatever secondary value they may have, such as entertainment, formation, education, or a pleasurable experience—is to hold that their final worth is not derived from external or secondary ends. I call this collective set of views the end-in-itself view. Nicholas Stang recently leveled a twofold charge of reductio ad absurdum and operating from a double standard against the EI view. In this article, I refute Stang by showing that the (...) charges do not obtain for at least one variation of the EI view that holds artworks to be valuable for their own sake as internally purposive ends-in-themselves.

Despite their diversity and ecological importance, many areas of the SAR—Stramenopila, Alveolata, and Rhizaria—clade are poorly understood as the majority of SAR species lack molecular data and only 5% of species are from well-sampled families. Here, we review and summarize the state of knowledge about the three major clades of SAR, describing the diversity within each clade and identifying synapomorphies when possible. We also assess the “dark area” of SAR: the morphologically described species that are missing molecular data. The majority (...) of molecular data for SAR lineages are characterized from marine samples and vertebrate hosts, highlighting the need for additional research effort in areas such as freshwater and terrestrial habitats and “non-vertebrate” hosts. We also describe the paucity of data on the biogeography of SAR species, and point to opportunities to illuminate diversity in this major eukaryotic clade. See also the video abstract here: https://youtu.be/_VUXqaX19Rw. Despite their diversity, abundance, and importance, fewer than 10% of the species within the SAR—Stramenopila, Alveolata, and Rhizaria—clade have been assessed using molecular tools. Only a small percentage of the molecular records contain information on ecology or have associate location data, indicating a tremendous dark area. (shrink)

Some embodied theories of concepts state that concepts are represented in a sensorimotor manner, typically via simulation in sensorimotor cortices. Fred Adams (2010) has advanced an empirical argument against embodied concepts reasoning as follows. If concepts are embodied, then patients with certain sensorimotor impairments should perform worse on categorization tasks involving those concepts. Adams cites a study with Moebius Syndrome patients that shows typical categorization performance in face-based emotion recognition. Adams concludes that their typical performance shows that embodiment is false. (...) Moebius patients must draw on amodal (non-embodied) emotion concepts. In this paper, I review face-based emotion recognition studies with Moebius patients yielding conflicting results and diagnose these conflicts as a difference in experimental design. When emotion labels are provided, patients have typical performance, but when labels are not provided patients are severely deficient. I then show how an embodied, psychological constructionist view of emotions predicts and explains these performance differences. The upshot is that embodied theories of concepts are vindicated.

Synchronization of autonomic arousal levels within dyads and larger teams has been associated with several types of social-behavioral outcome. One previous study reported greater physiological influence of leaders on followers than of followers on leaders; influence was measured pairwise within triadic problem solving groups. The present study explored synchronized autonomic arousal with leadership outcomes in two experiments with group sizes of three to eight members. Drivers, who had the greatest physiological impact on other team members were consistently less like the (...) leader of the group. Empaths, who were the most receptive to autonomic signals from others, were not consistently associated with leadership roles, although they did show sensitivity to team dynamics in their ratings of cognitive and social sources of workload. The tentative conclusion, subject to future research, is that successful leadership requires a balance between the driver and empath orientations. (shrink)

Philosophers and cognitive scientists alike have recently been interested in whether cognition extends beyond the boundaries of skin and skull and into the environment. However, the extended cognition hypothesis has suffered many objections over the past few decades. In this paper, I explore the option of control extending beyond the human boundary. My aim is to convince the reader of three things: (i) that control can be implemented in artifacts, (ii) that humans and artifacts can form extended control systems, and (...) (iii) that perhaps extended control ought to be preferred over extended cognition. Using the objections to extended cognition as constraints on my own extended theorizing and the example of autofocus systems in cameras, I decompose and localize the components of an autofocus system that realize the central properties of control from a plausible theory of control in the literature. I then provide criteria according to which control can be extended in a system. Finally, I consider how this theory of extended control ought to be preferred to theories of extended cognition.

Abstractabstract:Hegel's end-of-art thesis is arguably the most notorious assertion in aesthetics. I outline traditional interpretive strategies before offering an original alternative to these. I develop a conception of art that facilitates a reading of Hegel on which he is able to embrace three seemingly contradictory theses about art, namely, (i) the end-of-art thesis, (ii) the continued significance of art for its own sake (autonomy thesis), and (iii) the necessity of art for robust knowledge (epistemicnecessity thesis). I argue that Hegel is (...) able to embrace all three theses at once through a conception of the work of art as an internally purposive whole (what I call the "IP View" of art). On the IP View, because of the kind of wholes that artworks are, they (i.a) are valuable for their own sake as ends-in-themselves, (i.b) yield valuable experiences because they are valuable for their own sake, and thereby (i.c) are necessary for robust knowledge. Finally, I suggest that not only does Hegel appear to hold the IP View of art, but also that on such a view, there is a very sensible reason for affirming (one reading of) Hegel's end-of-art thesis as an important means to establishing art's actual significance for robust knowledge against soaring, but unsubstantiable, claims about art's potency with respect to robust knowledge.

Māori (Indigenous people of New Zealand (NZ)) suffer food insecurity disproportionately in New Zealand. Some research suggests that Māori value mātauranga Māori (traditional Māori knowledge) when it comes to the collection, preparation and eating of kai (food). This study explores the connections between mātauranga Māori and kai in regional NZ schools for potential pathways to impact food security for children. Semi-structured interviews were undertaken with five primary school principals in the Hawke’s Bay region. Principals were purposively selected on commitments to (...) proactively incorporating mātauranga Māori into their school environment. Reflective thematic analysis was used to analyse the data. Three main themes were identified: teaching and learning around mātauranga Māori and kai; environmental sustainability and the sustainability of kai initiatives; and school values. A strong emphasis was placed on the learning of traditional Māori values around kai and the whenua (land) and the sustainability of teaching programs. School values were invariably bound in Te Ao Māori (a Māori worldview) however, schools felt challenged in aligning their values and their mātauranga Māori-bound teaching practices with the current food provision programme in their schools (Ka Ora, Ka Ako). The programme’s strict nutritional guidelines appeared to challenge traditional Māori approaches to kai. Schools remain an ideal environment for the incorporation of mātauranga Māori to support food security and food education, and future work should explore a demonstration project that incorporates the knowledge gained in this study and ways to integrate mātauranga Māori into Ka Ora, Ka Ako.

This paper compares Heidegger’s “dasein-centric” existential hermeneutic to Levinas’s primacy of the Other and the importance the latter places on the ethical relationship. Invoking the concepts of totality and infinity, the paper discusses the ways in which one encounters the Other and how signification arises from the ethical relationship. This is followed by a discussion of how Levinas’s ethics might influence existential phenomenological research methodology, pointing to the ethical demands described by Levinas as seeming to have priority over the praxis (...) of research insofar as the Other calls us beyond the methodological framework. Finally, the paper considers the extent to which the ethical demands of Levinas’s phenomenology are met by the special place of the research participant and the attitude of empathic presence prescribed within the Heideggerian framework.

We highlight a recent study exploring the hand‐off of UV damage to several key nucleotide excision repair (NER) proteins in the cascade: UV‐DDB, XPC and TFIIH. The delicate dance of DNA repair proteins is choreographed by the dynamic hand‐off of DNA damage from one recognition complex to another damage verification protein or set of proteins. These DNA transactions on chromatin are strictly chaperoned by post‐translational modifications (PTM). This new study examines the role that ubiquitylation and subsequent DDB2 degradation has during (...) this process. In total, this study suggests an intricate cellular timer mechanism that under normal conditions DDB2 helps recruit and ubiquitylate XPC, stabilizing XPC at damaged sites. If DDB2 persists at damaged sites too long, it is turned over by auto‐ubiquitylation and removed from DNA by the action of VCP/p97 for degradation in the 26S proteosome. (shrink)

Fluctuations in attentional state and their relation to goal neglect were examined in the current study. Participants performed a variant of the Stroop task in which attentional state ratings were given prior to each trial. It was found that pre-trial attentional state ratings predicted subsequent trial performance, such that when participants rated their current attentional state as highly focused on the current task, performance tended to be high compared to when participants reported their current attentional state as being unfocused on (...) the current task. This effect was larger for incongruent than congruent trials leading to differences in the magnitude of the Stroop effect as a function of pre-trial attentional state. Furthermore, variability in attentional state was correlated with overall levels of performance, and when attentional state was covaried out, the Stroop effect was greatly reduced. These results suggest a link between fluctuations in pre-trial attentional state and goal neglect. (shrink)

This paper explores the ethical dimensions of lionfish removal and provides an argument supporting hunting lionfish for consumption. Lionfish are an invasive species found around the world. Their presence has fueled management strategies that predominantly rely on promoting human predation and consumption. We apply rights-based ethics, utilitarian ethics, and ecocentric environmental ethics to the question of whether hunting and eating lionfish is ethical. After applying these perspectives, we argue that, from a utilitarian perspective, lionfish should be culled. Rights-based ethics, on (...) the other hand, are not applicable in this case, while ecocentric environmental ethics would support lionfish removal. (shrink)
