How Policy Influences Aggression in Nightlife Spaces: A Proposed Core Aggression Cycle.

This theoretical review examines prior theories that aim to explain the disproportionate amount of violence in Nighttime Entertainment Precincts (NEPs) and proposes a comprehensive model that links violence to policy and environmental changes. To understand why this violence occurs and better inform prevention and intervention, a theoretical review using a "people" in "places" approach was conducted. This perspective considers the precursors of violence both at the individual level and among a group within a shared environment. Prior public health, criminology, and economic theories that aim to explain why violence occurs in NEPs provide a limited perspective, each only capturing part of the story. Further, prior theories fall short of demonstrating how policy and environmental changes in an NEP can influence the psychological determinants of aggression. When unified in a social-ecological framework, they can provide a more holistic explanation of violence in NEPs. We propose the Core Aggression Cycle (CAC) model, which draws from the prior theories examining violence in NEPs, and psychological theories of aggression. The CAC model is a proposed basis for unifying future research across disciplinary discourses. The CAC provides a clear conceptual framework that has the capacity to incorporate multiple previous and future theoretical perspectives on how alcohol policy and the environment influence violence within nightlife spaces. The CAC can be used by policy makers to establish new policy, critically evaluate existing policy, and determine whether policy adequately addresses the underlying mechanisms that produce violence in NEPs.

The importance of acculturation orientation in understanding the impact of pre- and post-migration stressors on behavioral health: Evidence from a crisis migrant sample.

We examine the interplay of acculturation orientation, cultural stress, and hurricane trauma exposure with behavioral health among Puerto Rican crisis migrants who relocated to the US mainland after Hurricane Maria. Participants were 319 adult (Mage = 39 years; 71% female; 90% arriving in 2017-2018) Hurricane Maria survivors surveyed on the US mainland. Latent profile analysis was used to model acculturation subtypes. In turn, ordinary least squaresregression was executed to examine the associations of cultural stress and hurricane trauma exposure with behavioral health while stratifying by acculturation subtype. Five acculturation orientation subtypes were modeled, three of which-Separated (24%), Marginalized (13%), and Full Bicultural (14%)-align closely with prior theorizing. We also identified Partially Bicultural (21%) and Moderate (28%) subtypes. Stratifying by acculturation subtype, with behavioral health (depression/anxiety symptoms) specified as the dependent variable, hurricane trauma and cultural stress accounted for only 4% of explained variance in the Moderate class, a somewhat greater percentage in the Partial Bicultural (12%) and Separated (15%) classes, and substantially greater amounts of variance in the Marginalized (25%) and Full Bicultural (56%) classes. Findings underscore the importance of accounting for acculturation in understanding the relationship between stress and behavioral health among climate migrants.

Corruption and Political Support: The Case of Peru’s Vacuna-gate Scandal

AbstractClassic theories of public opinion suggest that negative shocks can undermine system support in weak democracies, but scant work has systematically assessed this thesis. We identify Peru’s explosive Vacuna-gate scandal as a most-likely case for finding a connection between corruption and political support. The scandal’s unexpected revelation in the middle of the 2021 AmericasBarometer Peru survey created conditions for a natural experiment. Applying an unexpected-event-during-survey design, we consider the consequences of the scandal for perceptions of corruption, system support, and support for democracy. We find robust evidence that the scandal increased even already high perceptions of corruption and lowered system support. Contrary to expectations derived from prior theories, we find no effect on explicit support for democracy. In the conclusion, we discuss the nuanced ways that scandal may shape democratic stability.

Invoking Self-Related and Social Thoughts Impacts Online Information Sharing.

Online sharing impacts which information is widely available and influential in society. Yet, systematically influencing sharing behavior remains difficult. Past research highlights two factors associated with sharing: the social and self-relevance of the to-be-shared content. Based on this prior neuroimaging work and theory, we developed a manipulation in the form of short prompts that are attached to media content (here health news articles). These prompts encourage readers to think about how sharing the content may help them to fulfill motivations to present themselves positively (self-relevance) or connect positively to others (social relevance). Fifty-three young adults completed this pre-registered experiment while undergoing fMRI scanning. Ninety six health news articles were randomly assigned to three within-subject conditions that encouraged self-related or social thinking, or a control. Invoking self-related or social thoughts about health-related news (vs. control) 1) causally increased brain activity in a priori regions of interest chosen for their roles in processing social and self-relevance and 2) causally impacted self-reported sharing intentions. This study provides evidence corroborating prior reverse inferences regarding the neural correlates of sharing. It further highlights the feasibility and utility of targeting neuropsychological processes to systematically facilitate online information spread.

Transactive memory system (TMS) and knowledge sharing: The effects of social capital and task visibility

Knowledge sharing plays a fundamental role in the mobile social media context. However, users are more likely to believe that their knowledge sharing is not worth the effort and time given high expectation of receiving some value in return. Social media have limited value if users are not willing to share knowledge. Knowledge sharing with the consideration of transactive memory system (TMS) from the perspectives of social capital and task visibility was examined. Building on prior theories and literature, a TMS knowledge sharing research model was developed. Data were collected from users of social media mobile apps. Results show that TMS is a valid second-order construct. From the social capital perspective, cognitive capital, relational capital and structural capital each have positive effects on TMS which further has a positive effect on knowledge sharing. From the task visibility perspective, knowledge sharing visibility has a positive effect on knowledge sharing.

Spatial structure and benefits to hosts allow plasmids with and without post-segregational killing systems to coexist.

To persist, a plasmid relies on being passed on to a daughter cell, but this does not always occur. Plasmids with post-segregational killing (PSK) systems kill a daughter cell if the plasmid has not been passed on. By killing the host, it also kills competing plasmids in the same host, something competing plasmids without a similar system cannot do. Accordingly, plasmids with PSK systems can displace other plasmids. In nature, plasmids with and without PSK systems coexist and prior theory has suggested this is expected to be very rare or unstable, such that one or the other type of plasmid eventually takes over. Here, we show that if there is spatial structure and plasmids confer benefits to hosts, coexistence of plasmids occurs broadly. Often plasmids confer benefits (even ones with a PSK system) and bacteria are often spatially structured. So, our results may be generally applicable.

Serendipity and management accounting change

PurposeThis study aims to explore the serendipitous discovery of integrated reporting (IR) by Alpha, an Italian small and medium-sized enterprise (SME). Alpha piqued the curiosity when the authors discovered that it experimented with IR alongside other management accounting practices, such as the Balanced Scorecard. As the authors reflected on Alpha’s experiences, the authors had to opportunistically develop a new framework to understand the change that was taking place at Alpha fully. Thus, the authors developed the serendipitous drift framework. This study contributes to addressing the gap between management accounting research that sees change as a planned, ordered process versus research that sees it as an unmanageable drift.Design/methodology/approachThe authors ground the research on a qualitative methodology based on a single case study. This methodology allows us to focus on understanding what has happened at Alpha to discover new themes and provide theoretical generalisations. The authors developed the framework using middle-range thinking and fleshed it out using empirical findings from the case study. Middle-range thinking implies going back and forth between the theory and the empirical material. Therefore, the authors develop the serendipitous drift framework from prior theories and use it to inform the empirical study. In turn, the empirical material collected in Alpha helps refine and flesh out the serendipitous drift framework. The framework explains how Alpha leveraged serendipity to steer change towards favourable outcomes for them.FindingsThe authors find that the search for change undertaken by Alpha’s managers was non-specific but purposeful. Their dispositions were sagacious enough to recognise the potential value found in management accounting practices, such as IR and the Balanced Scorecard. They chanced upon new and unforeseen practices through trial and error, iteration, internal engagement and networking.Research limitations/implicationsOverall, the results indicate that Alpha’s managers shaped the disorder of management accounting changes, even though it followed unexpected, uncertain and messy paths. Indeed, appropriate informal controls can act as a frame of reference for choosing, adapting and implementing new management accounting practices to shape the disorder. Informal controls can both guide and bound the experimentation process towards desirable outcomes.Originality/valueThe authors contribute to management accounting change theory by developing a framework rooted in serendipity and drifting theories. The framework identifies how searching, sagacity and chance are essential for making positive, unexpected discoveries. Therefore, the authors provide novel insights on how and why IR and other management accounting practices are eventually translated and adopted in the case company. Moreover, the serendipitous drift framework has the potential to help managers frame cultural controls to actively seek opportunities for valuable serendipitous eureka moments through networking and experimentation.

Review: Pastels and Pedophiles: Inside the Mind of QAnon, by Mia Bloom and Sophia Moskalenko

This book is an excellent introduction to the origins of the QAnon posts (“drops”), their origin and history, the constituencies who were most influenced by QAnon, why people were attracted to the worldview, and what can be done when family members go down the rabbit hole of QAnon conspiracy theories.Mia Bloom is a political scientist who researches and publishes on various aspects of terrorism studies. Sophia Moskalenko is a psychologist who studies “mass identity, inter-group conflict, and conspiracy theories” (back cover flap). She has published books on how conflict contributes to radicalization and on the attraction of martyrdom. Pastels and Pedophiles is written in the combined voice of the two authors. Due to their different specializations, it is possible to distinguish one author’s writing from the other’s but this does not detract from the cohesion of the book.Chapter 1, “Looney Lies and Conspiracies: Making Sense of QAnon,” introduces the QAnon conspiracy theories, describes the origin of QAnon posts on 28 October 2017, discusses QAnon-supporting candidates for political office in 2020 and the ones elected to Congress, and reports statistics showing the growing percentage of QAnon believers in the United States—from 5 percent in 2019 to 17 percent in February 2021 (3). This chapter explores evidence for who QAnon poster(s) might have been. The authors demonstrate how the QAnon conspiracy theories are modeled on prior antisemitic conspiracy theories, notably the fictitious pamphlet, The Protocols of the Elders of Zion (1902/1903) produced in Russia. The QAnon conspiracy theory that Democrats and their Hollywood elite supporters kidnap and torture children to extract a chemical that they use to keep themselves youthful is a reformulation of the old “blood libel” Christian conspiracy theory against Jews. Democrats are also accused of child sex-trafficking in the QAnon conspiracy theories. The chapter describes QAnon as a collection of conspiracy theories with believers continuing to create new variations.Chapter 2, which examines the 6 January 2021 insurrection, links former President Donald Trump’s supporters’ belief in QAnon conspiracy theories with the attempt to overthrow the outcome of the 2020 presidential election by attacking Congress. The chapter delves into contributing factors for people’s acceptance of QAnon conspiracy theories, including former military personnel suffering from PTSD, troubled family or personal backgrounds, and the monetization of QAnon merchandise. QAnon was marketed to women’s concerns about protecting children in posts in pastel colors. The authors argue that the COVID-19 pandemic and the subsequent shutdowns and social isolation contributed to more people reading QAnon conspiracy theories online and becoming converted.Chapter 3 looks at the radicalization of QAnon believers. It discusses how QAnon adherents say their conversion is similar to the character Neo in The Matrix (1999), who takes a red pill that awakens him to reality. This chapter also considers the QAnon belief in Trump as a savior, “the ultimate masculine hero who would rescue abused children” (100). In this regard, Bloom and Moskalenko argue that QAnon is “a kind of religion” (98). According to the authors,FolQlore satisfies four important needs for QAnon followers: a need to feel smart (cognitive utility); a need to feel connected (social utility); a need to feel positive emotions (emotional utility); and a need to feel like one’s life has a purpose (personal utility). (104)Chapter 4 explores the movement after the 6 January 2021 assault against the Capitol, when QAnon believers sorted themselves into “the Diehards,” “the Doubters,” and “the Defectors.” Strategies to promote critical thinking and social media literacy among Americans are discussed. The authors assert that online efforts to utilize QAnon to divide Americans have particularly originated from Russia (123–4, 132). Concerning the types of people who attacked the Capitol on 6 January, the chapter cites studies concluding that 68 percent of those individuals had psychopathologies (137). Steven Hassan’s theory of mind control is mentioned briefly (141) but not emphasized. Reflecting Moskalenko’s background in psychology, the authors recommend mindfulness-based stress reduction (MBSR) formulated by Jon Kabat-Zinn as a way that people can cope with their concerns without resorting to conspiracy theories (147–8).Chapter 5, “Qontagion,” traces the spread of QAnon conspiracy theories worldwide and the appeal of QAnon to evangelical Christians. The role of Vladimir Putin utilizing online trolls to spread QAnon conspiracy theories in social media is also considered. The authors conclude that “QAnon’s spread is a well-executed psyop…a speciality of Putin’s KGB training” (169).The final chapter, “FAQs,” answers questions about QAnon, including how best to deal with family members who are QAnon adherents with varying levels of commitment and radicalization.Pastels and Pedophiles is an indispensable study of all aspects of the QAnon conspiracy theories for scholars studying and teaching about the movement.

THE INFLUENCE OF INSTAGRAM SOCIAL MEDIA MARKETING AND TECHNOLOGY READINESS TO INCREASE PURCHASE INTENTION THROUGH SOCIAL MEDIA BRAND ENGAGEMENT MEDIATION ON X INSTANT MORTAR BRAND

The Covid-19 has disrupted several businesses marketing strategies. This also has an effect on the building materials industry, they have to adapting its marketing to the B2C market via social media. Social Media Marketing can increase a customer's interest in making purchase, according to the findings of prior study and theory; yet, the company's data reveals various outcomes. There was a strong response to the social media marketing campaign, however the number of sales was not related to the number of sales the company made. Consequently, this study will assess the impact of Social Media Marketing on Purchase Intention as mediated by Social Media Brand Engagement, and considering the Technology Readiness. 150 Instagram followers of Mortar Instant X were surveyed using a quantitative way to acquire data for this study. According to the findings, Social Media Marketing has a positive direct and indirect influence (mediated by Social Media Brand Engagement) on Purchase Intention. Meanwhile, Technology Readiness has a positive direct and indirect effect (mediated by Social Media Brand Engagement) on Purchase Intention. It is anticipated that Instant Mortar X and the construction materials industry would use the findings of this study to develop and implement social media marketing strategies.

A longitudinal approach to understanding boredom during pandemics: The predictive roles of trauma and emotion dysregulation.

Research during the COVID-19 pandemic and prior outbreaks suggest that boredom is linked to poor compliance with critical lifesaving social distancing and quarantine guidelines, as well as to numerous mental health difficulties. As such, continued understanding on what contributes to boredom is imperative. Extending beyond the roles of constraint, monotony, and trait dispositions (e.g., individual differences in boredom propensity), and informed by prior theories on the emotional contributors of boredom, the current longitudinal study examined the predictive role of "pandemic trauma" on people's boredom, with a focus on how emotion dysregulation mediates this relationship. Community participants (N = 345) completed questionnaires three times across an average of 3 1/2 weeks, rating their pandemic trauma, emotion dysregulation, and boredom over the past week each time. Pandemic trauma was assessed with items querying exposure to coronavirus, as well as the financial, resource-related, and interpersonal pandemic stressors that participants experienced. Emotion dysregulation was assessed with the Difficulties in Emotion Regulation Scale. Boredom was assessed with the short-form Multidimensional State Boredom Scale. The results of a theory-informed mediation model showed that participants' pandemic trauma at Time 1 positively and modestly predicted their boredom at Time 3 and that this relationship was partially and moderately mediated by participants' lack of emotional clarity and difficulties with engaging in goal-directed behaviors at Time 2. When people experience pandemic-related trauma, they subsequently struggle to understand their feelings and engage in goal-oriented actions, and, in turn, feel more bored. Theoretical and clinical implications as related to the emotional underpinnings of boredom are discussed.

Optimal dormancy strategies in fluctuating environments given delays in phenotypic switching

Organisms have evolved different mechanisms in response to periods of environmental stress, including dormancy – a reversible state of reduced metabolic activity. Transitions to and from dormancy can be random or induced by changes in environmental conditions. Prior theoretical work has shown that stochastic transitioning between active and dormant states at the individual level can maximize fitness at the population level. However, such theories of ‘bet-hedging’ strategies typically neglect certain physiological features of transitions to dormancy, including time lags to gain protective benefits. Here, we construct and analyze a dynamic model that couples stochastic changes in environmental state with the population dynamics of organisms that can initiate dormancy after an explicit time delay. Stochastic environments are simulated using a multi-state Markov chain through which the mean and variance of environmental residence time can be adjusted. In the absence of time lags (or in the limit of very short lags), we find that bet-hedging strategy transition probabilities scale inversely with the mean environmental residence times, consistent with prior theory. We also find that increasing delays in dormancy decreases optimal transitioning probabilities, an effect that can be influenced by the correlations of environmental noise. When environmental residence times – either good or bad – are uncorrelated, the maximum population level fitness is obtained given low levels of transitioning between active and dormant states. However when environmental residence times are correlated, optimal dormancy initiation and termination probabilities increase insofar as the mean environmental persistent time is longer than the delay to reach dormancy. We also find that bet hedging is no longer advantageous when delays to enter dormancy exceed the mean environmental residence times. Altogether, these results show how physiological limits to dormancy and environmental dynamics shape the evolutionary benefits and even viability of bet hedging strategies at population scales.

The transformation of identity of secondary school teachers: Professional development and English language education strategies in Hong Kong during the COVID-19 pandemic

The disruptive effects of this pandemic are predicted to redefine the priorities of continuing professional development (CPD) in the educational sector and reconstruct the identity and role of educators in future educational systems. Accordingly, the primary aim of the proposed research is to critically assess the factors shaping post-Covid-19 identity formation amongst secondary school teachers in Hong Kong to determine the influence of CPD and systemic needs on teacher role perceptions and goal-setting. This study will apply a mixed-methods approach to the collection of quantitative (survey) and qualitative (interview) data from a sample of Hong Kong educators. Through a critical, comparative analysis of these findings and triangulation of the evidence with prior academic theories, a model of educator development and identity formation will be proposed to improve and target developmental support throughout normalisation and post-Covid-19 recovery.

Progressive or pressuring? The signaling effects of egg freezing coverage and other work-life policies.

In recent years, organizations have expanded the number and types of work-life policies they offer in an attempt to attract and retain talent. We challenge the assumption that work-life policies uniformly signal personal-life support and elicit favorable employee attitudes by investigating a relatively new work-life policy: egg freezing coverage. We theorize that, relative to other work-life policies, egg freezing coverage is more likely to send signals that evoke negative employee attitudes; although framed as intended to support employees' personal lives, employees interpret egg freezing as signaling that personal-life sacrifice and work prioritization are encouraged, which in turn decrease policy support and organizational attraction. We test these ideas in six studies, including an archival study, a qualitative survey study, a scale development study, two quantitative survey studies, and an experiment. We find egg freezing coverage evokes more negative attitudes than a range of other work-life policies (in vitro fertilization [IVF], on-site childcare, paid parental leave, flextime) as well as no policy at all. More negative reactions to egg freezing than to other policies are driven by perceptions that the policy sends a stronger signal that personal-life sacrifice is encouraged, as well as perceptions that it offers fewer benefits to employees and is more costly to organizations. In all, this work expands understanding of the signaling effects of work-life policies and demonstrates that reactions to a range of work-life policies are both more variable and driven by a larger number of underlying factors than prior theory can account for.

Solitary Confinement and Prison Personnel: Emotional numbing as a response to work in extended restrictive housing*

Drawing on prior theory and research, this study develops and tests hypotheses about the potential for work in extended restrictive housing (ERH), which entails solitary confinement, to contribute to emotional numbing among personnel. It draws on a mixed-methods approach using data from a large-scale survey and from focus groups and interviews with correctional personnel. As compared to work in general population housing (GPH), ERH work was reported to be associated with greater emotional numbing due in part to unique aspects of this work. The numbing effects, then, may have adverse consequences for personnel's mental and physical health and relationships. Implications for understanding the punitive era and social order in prisons are discussed.

Value Theory: Critical Analysis and Theory Construction

This paper covers a review of theory construction, a critical analysis of prior “value theory”, and an attempt in a comprehensive value theory construction. Prior value theory in the Economics literature has been highly fragmented, and left a gap between value and modern economic theory. This new value theory explains the gap and amalgamates the various perspectives of value. The outcome includes a theoretical statement and supporting propositions.

Developing and testing an integrated patient mHealth and provider dashboard application system for type 2 diabetes management among Medicaid-enrolled pregnant individuals based on a user-centered approach: Mixed-methods study.

A tailored and integrated technology solution (patient mHealth application and provider dashboard) can provide a 360° view of Medicaid-enrolled patients with type 2 diabetes (T2D) during pregnancy that could improve health outcomes and address health inequities. To develop a set of user specifications for the mHealth and dashboard applications, develop prototypes based on user needs, and collect initial impressions of the prototypes to subsequently develop refined tools that are ready for deployment. Study activities followed a double-diamond framework with a participatory design mindset. Activities were divided into two phases focused on a qualitative inquiry about participant needs and values (phase 1) and design, development, and usability testing of low and high-fidelity prototypes (phase 2). We identified themes that exemplified pregnancy experience among Medicaid-enrolled individuals with T2D. Patients (n = 7) and providers (n = 7) expressed a core set of expectations for the mHealth and dashboard applications. Participants provided feedback to improve the mHealth and dashboard. For both applications, participants reported scores for the NASA Task load Survey (TLX) that were in the 20th percentile of national TLX scores. Digital health tools have the ability to transform health care among Medicaid-enrolled patients with T2D during pregnancy, with the goal of managing their blood glucose levels, which is a precursor to experiencing a successful pregnancy and birth. Distilling patient and provider needs and preferences-then using them, along with prior studies and theory, to develop applications-holds great potential in tackling complicated health care issues.

An analysis of enterprise resource planning systems and key determinants using the Delphi method and an analytic hierarchy process

<abstract> <p>Enterprise resource planning (ERP) systems are software module packages which can be customized up to a certain limit to suit the specific needs of each organization. Many ERP projects have not been effective at achieving all of the intended results due to high cost and high failure risks in ERP implementation. This study integrates the prior theories and knowledge gained from several textile industry practitioners for ERP projects. A two-stage method involving the Delphi and analytic hierarchy process decision support methodology was conducted. Based on the case of the textile industry in Taiwan, the findings illustrate the top 10 key factors: a clear project plan by defined ERP capacity requirement; a limited scope and focused flowchart; goal congruence between ERP project implementation and corporate strategy; top management support and commitment; the extent of standard operating procedures and institutional processes; a user-friendly interface; systems integrated with aggressive schedules and timelines; provision of technical assistance for rapid, effective transfer of best practice interventions; good interdepartmental communication and coordination on a focused issue solution; and enablement of business process reengineering and solid management for project team building. The findings of this research will be beneficial to those apparel companies that adopted the ERP.</p> </abstract>

COVID-19 WIDOWHOOD OR PANDEMIC WIDOWHOOD: EXAMINING THE DIFFERENTIAL IMPLICATIONS FOR MENTAL HEALTH

Abstract Millions of COVID-19 widows worldwide face elevated mental health risks that foreshadow worsening physical health and elevated mortality. It remains unknown whether the excess mental health problems for COVID-19 widows are a result of the “bad death” experiences from COVID-19 (e.g., unexpected death and high levels of medical intervention) or pandemic-induced social changes (e.g., social isolation and limited funerals). This study examines whether older adults whose spouses died of COVID-19 disease have worse mental health (self-reported depression, loneliness, and trouble sleeping) than those whose spouses died from causes other than COVID-19 before and during the pandemic. We used Survey of Health, Ageing and Retirement in Europe data collected before (Wave 8, fielded October 2019 to March 2020) and during the pandemic (COVID-19 Supplement-2, fielded June to August 2021) to compare three groups whose spouses died (a) before the pandemic, (b) from COVID-19 during the pandemic, and (c) from non-COVID-19 causes during the pandemic. We find those spouses died from COVID-19 have higher risks of self-reported depression, loneliness, and trouble sleeping than those losing a spouse before the pandemic. However, losing a spouse due to non-COVID-19 causes during the pandemic is not significantly associated with worse mental health compared to pre-pandemic scenarios. During the pandemic, older adults whose spouses died from COVID-19 report higher risks of loneliness than those spouses died from non-COVID-19 causes. This study suggests losing a spouse due to COVID-19 presents unique mental health risks for older adults, clarifying prior theories about mental health impacts of pandemic bereavement.

Bridging as Metaphor- A Systems Thinking Approach for Exploring Transboundary Risk

This paper provides a novel approach for understanding transboundary risk, including ‘grand challenges’ such as climate change. Discussion begins with an exploration of the origins of transboundary risk as a byproduct of globalization. Thereafter, the concept of ‘bridging’ is used in order to conceptualize the spread of transboundary risk across traditional physical boundaries, including geographic borders. Building upon prior theory, systems thinking and complexity are used as conceptual lenses for understanding the dynamics of transboundary risk. Scenario planning is offered as a means for envisioning and addressing the challenges presented by transboundary risk. The result of this discussion is a holistic, systems view of transboundary risk which stands in contrast to traditional, reductionist perspectives of risk. As such, the paper concludes by proposing a set of epistemological questions that emerge as a result of this shift.

Biobehavioral and psychosocial stress changes during three 8-12month spaceflight analog missions with Mars-like conditions of isolation and confinement.

Prior theories about individual and team adaptation to living and working in an isolated and confined environment (ICE) have been derived from the experiences of individuals who winter-over in Antarctica or deploy for long durations in submarines. These theories are typically described as a 3- to 4-stage process with phases of excitement and elevated alertness, then followed by difficult phases, including depression and volatility. To further evaluate the applicability of these theories to long-duration human spaceflight missions, longitudinal stress responses to prolonged isolation and confinement of three 6-person crews during 8-12months simulated Mars missions were characterized through metabolite profiling (biomarkers in hair and urine samples), wearables monitoring (sleep and activity levels), and self-reported ratings of stress, mood, social participation, and perceived health. These data were normalized, aggregated, and clustered to analyze longitudinal trends in biobehavioral and psychosocial stress measures. As a result, this analysis presents a theoretical model that triangulates aspects of prior theories with new evidence to describe ICE stress at HI-SEAS as 1) eustress of initial adaptation (high stress hormone levels at mission start), 2) deprivation due to prolonged isolation and confinement (decreasing dopamine and serotonin levels), 3) disruption of individual and team dynamics (changes in activity levels, mood, perceived stress, and social participation) and 4) asynchronous coping (changes in sleep-wake cycles, outlook, and team cohesion). These findings support several aspects of prior theories in combination, such as the elevated alertness at mission start and that adverse conditions are most likely to develop after the halfway point of a mission (e.g. for HI-SEAS 8-12months missions, after approximately 6months) followed by a period of volatility until the end (e.g. as stated in Rohrer's theory, ups and downs until the end, not a renewed outlook at the end as described in 3rd quarter phenomenon theory).
