Annual Research Review: The Power Of Predictability – Patterns Of Signals In Early Life Shape Neurodevelopment And Mental Health Trajectories, Elysia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

The global burden of early life adversity (ELA) is profound. The World Health Organization has estimated that ELA accounts for almost 30% of all psychiatric cases. Yet, our ability to identify which individuals exposed to ELA will develop mental illness remains poor and there is a critical need to identify underlying pathways and mechanisms. This review proposes unpredictability as an understudied aspect of ELA that is tractable and presents a conceptual model that includes biologically plausible mechanistic pathways by which unpredictability impacts the developing brain. The model is supported by a synthesis of published and new data illustrating the significant …

Understanding The Consumption Of Antimicrobial Resistance–Related Content On Social Media: Twitter Analysis, Hyunuk Kim, Chris R. Proctor, Dylan Walker, Ronan R. Mccarthy

Business Faculty Articles and Research

Background: Antimicrobial resistance (AMR) is one of the most pressing concerns in our society. Today, social media can function as an important channel to disseminate information about AMR. The way in which this information is engaged with depends on a number of factors, including the target audience and the content of the social media post.

Objective: The aim of this study is to better understand how AMR-related content is consumed on the social media platform Twitter and to understand some of the drivers of engagement. This is essential to designing effective public health strategies, raising awareness about antimicrobial …

The Human-computer Interaction (HCI) community has the opportunity to foster the integration of research practices across the Global South and North to begin overcoming colonial relationships. In this paper, we focus on the case of Latin America (LATAM), where initiatives to increase the representation of HCI practitioners lack a consolidated understanding of the practices they employ, the factors that influence them, and the challenges that practitioners face. To address this knowledge gap, we employ a mixed-methods approach, comprising a survey (66 respondents) and in-depth interviews (19 interviewees). Our analyses characterize a set of research perspectives on how HCI is practiced …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

Understanding Integral Peace Leadership In Practice: Lessons And Learnings From Women Peacemaker Narratives, Whitney Mcintyre Miller, Miznah Omair Alomair

Education Faculty Articles and Research

Integral peace leadership is an emergent framework that creates space for just change by challenging violence and aggression while building positive systems and structures. This article utilizes a deductive qualitative analysis strategy to critically examine the proposed concepts of integral peace leadership to determine their saliency for peacebuilding practice. Utilized to study these concepts are 10 Women PeaceMakers’ narratives. Results indicate that 25 of the 35 concepts studied across four quadrants were relevant in the women’s peace leadership work, with an additional six concepts revealed. The analysis demonstrates that the concepts of integral peace leadership are present in the work …

Kagame’S Ruse In Rwanda: The Debilitating Role Of Authoritarianism In Rwanda And Its Impact On Long Term, Sustainable Development, Manuel Grajeda

International Studies (MA) Theses

Following the genocide in 1994, Rwanda has been touted as a major, international development success, gaining praise and attention from the international community who place the prosperity of the nation in the hands of Paul Kagame, the leader of the Rwandan Patriotic Front and the country’s current president. Indeed, under the leadership of Kagame the country was able to get through the horrors of mass killings and nationwide destruction and it is true that the country has made a serious turn around in the past 25 years. However, while the country is acclaimed to be a model for developed democracy …

Across Continents And Demographics, Unpredictable Maternal Signals Are Associated With Children's Cognitive Function, Elyssia Poggi Davis, Riikka Korja, Linnea Karlsson, Laura Glynn, Curt A. Sandman, Brian Vegetabile, Eeva-Leena Kataja, Saara Nolvi, Eija Sinervä, Juho Pelto, Hasse Karlsson, Hal S. Stern, Tallie Z. Baram

Psychology Faculty Articles and Research

Background

Early life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life.

Sexuality Through The Lens Of Secure Base Attachment Dynamics: Individual Differences In Sexploration, Dylan Selterman, Amanda N. Gesselman, Amy C. Moors

Psychology Faculty Articles and Research

A key aspect of attachment functioning is the secure base, which empowers people to explore their environments, though some individuals do this more effectively than others. While most researchers have focused on adult attachment dynamics in terms of stress and threat (safe haven), we argue that concerted attention should also focus on relational processes in times of optimal functioning. In this paper, we introduce a new theoretical concept: secure base sexual exploration (or sexploration). We define this as the degree to which individuals are able to effectively explore multifaceted dimensions of sexuality (e.g., behaviors, identity) as a function …

Through Community Eyes: The Transition Of International Organizations From Community Aid To Development In Postconflict Sierra Leone, Whitney Mcintyre Miller

Education Faculty Articles and Research

Sierra Leone experienced an 11-year civil war, brutalizing its people and destroying its communities. With the cessation of violence, international organizations helped to secure peace, deliver aid and supplies, and, after, assist with development projects. This grounded theory study, which aims to understand the role these organizations played from the viewpoint of community members in 2 communities, posits that community members’ regard of international organizations lessened as their efforts transitioned from securing the peace and relief efforts to aid for development. Highlighted are the successes and challenges of this work and a broad discussion of implications and recommendations.

Information Transmission And The Oral Tradition: Evidence Of A Late-Life Service Niche For Tsimane Amerindians, Eric Schniter, Nathaniel T. Wilcox, Bret A. Beheim, Hillard S. Kaplan, Michael Gurven

ESI Publications

Storytelling can affect wellbeing and fitness by transmitting information and reinforcing cultural codes of conduct. Despite their potential importance, the development and timing of storytelling skills, and the transmission of story knowledge have received minimal attention in studies of subsistence societies that more often focus on food production skills. Here we examine how storytelling and patterns of information transmission among Tsimane forager-horticulturalists are predicted by the changing age profiles of storytellers’ abilities and accumulated experience. We find that storytelling skills are most developed among older adults who demonstrate superior knowledge of traditional stories and who report telling stories most. We …

Developmental Origins Of The Human Hypothalamic-Pituitary-Adrenal Axis, Mariann A. Howland, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Introduction: The developmental origins of disease or fetal programming model predicts that intrauterine exposures have life-long consequences for physical and psychological health. Prenatal programming of the fetal hypothalamic-pituitary-adrenal (HPA) axis is proposed as a primary mechanism by which early experiences are linked to later disease risk.

Areas covered: This review describes the development of the fetal HPA axis, which is determined by an intricately timed cascade of endocrine events during gestation and is regulated by an integrated maternal-placental-fetal steroidogenic unit. Mechanisms by which stress-induced elevations in hormones of maternal, fetal, or placental origin influence the structure and function …

Leadership For Sustainability And Peace: Responding To The Wicked Challenges Of The Future, Rian Satterwhite, Whitney Mcintyre Miller, Kate Sheridan

Education Faculty Books and Book Chapters

"In the past century our understanding of leadership has changed as the contexts in which leadership occurs evolve. Today, constructs of leadership that do not incorporate emergent concepts such as systems thinking no longer match the realities of the world in which it is exercised and the challenges it seeks to address. The challenges we face as a global community have increased in complexity, size, scope, and consequence. As a result of this contextual evolution, our definition of effective leadership is evolving as well."

Moving Forward In Sierra Leone: Community-Based Factors For Post Conflict Development, Whitney Mcintyre Miller

Education Faculty Articles and Research

War and conflict, while not manifested as economic or natural disaster, often bring the same consequences and damages and require similar capacity building. This article discusses the following four community-based factors, which contributed to the postconflict development of two communities in Sierra Leone, West Africa: (a) the inclusive involvement of community members for development and construction projects, (b) the use of culturally responsive practices in community building, (c) leadership that is directly connected with the community, and (d) the combination of traditional and local development practices with western and governmental practices. These factors were derived from an intensive five-week qualitative …

Prenatal Maternal Stress Programs Infant Stress Regulation, Elyssia Poggi Davis, Laura M. Glynn, Feizal Waffarn, Curt A. Sandman

Psychology Faculty Articles and Research

Objective: Prenatal exposure to inappropriate levels of glucocorticoids (GCs) and maternal stress are putative mechanisms for the fetal programming of later health outcomes. The current investigation examined the influence of prenatal maternal cortisol and maternal psychosocial stress on infant physiological and behavioral responses to stress.

Methods: The study sample comprised 116 women and their full term infants. Maternal plasma cortisol and report of stress, anxiety and depression were assessed at 15, 19, 25, 31 and 36 + weeks' gestational age. Infant cortisol and behavioral responses to the painful stress of a heel-stick blood draw were evaluated at 24 hours after …
