Volunteerism Among Older Adults In Singapore, Micah Tan, John Frederic Pedro Ortega, Nur Syafiqah Abdullah, Mindy Eiko Tadai, Rachel Wen Yi Ngu

ROSA Research Briefs

Volunteerism is recognised as a beneficial activity for individuals for many reasons. Beyond the potential of volunteerism to create new and meaningful communities (Hodge et al., 2013), it offers numerous benefits including improvement to one’s mental health (Willigen, 2000), self-esteem (Russell et al., 2018), and social connectedness (Hodge et al., 2013). Volunteering has also been found to provide a sense of purpose in one’s life (Schwingel et al., 2009). For these reasons and more, voluntary work among older adults may be a meaningful and effective pathway towards successful ageing, particularly for those in retirement. In Singapore, the National Volunteer and …

Forest Structure And Seasonally Inundated Grassland Shape Tropical Mammal Communities Under Moderate Disturbance, Juliana Masseloux, Quy Tan Le, Jessica Burr, Brian D. Gerber

Natural Resources Science Faculty Publications

Tropical biodiversity is threatened globally by anthropogenic disturbances, particularly forest degradation and overhunting. Where large mammals have been extirpated, smaller bodied “mesomammals” may play an important ecological role (e.g., as seed dispersers). However, these species are disproportionally affected by overhunting for wildlife trade markets and are routinely understudied as they tend to be rare, cryptic, and nocturnal. Few studies have examined spatiotemporal responses to anthropogenic disturbance by mesomammals at the community level, which may identify imbalances within an ecosystem that could threaten species persistence. We deployed camera traps throughout Cat Tien National Park (i.e., Nam Cat Tien area), southern Vietnam, …

Partial Ablation Of Postsynaptic Dopamine D2 Receptors In The Central Nucleus Of The Amygdala Increases Risk Avoidance In Exploratory Tasks, Eric Casey, María Elena Avale, Alexxai Kravitz, Marcelo Rubinstein

Open Access Publications

The central nucleus of the amygdala (CeA) is involved in the expression of fear and has been implicated in several anxiety disorders. This structure is densely innervated by DAergic projections that impinge on amygdalar neurons expressing various dopamine (DA) receptor subtypes, including D2 receptors (D2Rs). Although various pharmacological approaches have assessed the role of D2Rs in the CeA, the actual participation of postsynaptic D2Rs in the CeA to defensive behaviors remains unclear. Here, we investigated the distribution of D2Rs in the CeA and their role in modifying neuronal activity and fear related behaviors in mice. First, using the mouse reporter …

Fire Effects In Montane Meadows, Rosie Deak

Master's Theses

The impact of forest fires on downstream meadow communities across California is of great ecological interest, as meadows are an important source of biodiversity in this region. Over a century of fire suppression has led to increased forest stand densities, which in turn has resulted in less water availability due to increased transpiration of densely growing trees. This potentially has left less available water for downstream plant communities in meadows. If true, then high mortality wildfires in surrounding forest are predicted to lead to an increase in available downstream moisture where obligate and facultative-wetland taxa increase and dry-adapted upland taxa …

(Wp 2022-03) Managing Contagion: Covid, Public Health, And Reflexive Behavior, John B. Davis

Economics Working Papers

This paper characterizes a pandemic as one kind of contagion, and defines a contagion as a two-level, two-direction, reflexive feedback loop system. In such a system, experts’ opinions can act as self-fulfilling prophecies that significantly influence social behavior. Also, when multiple experts produce multiple, expert opinions can fragment a society’s response to a pandemic worsening rather than ameliorating it. This paper models this with two competing expert opinions, associates them with club goods and common pool goods types of circumstances, and argues that to combat fragmentation of opinion a focus on public health public good provision needs to be framed …

Queer And Convincing: Reviewing Freedom Of Religion And Lgbtq+ Protections Post-Fulton V. City Of Philadelphia, Arianna Nord

Washington Law Review

Recent increases in LGBTQ+ anti-discrimination laws have generated new conversations in the free exercise of religion debate. While federal courts have been wrestling with claims brought under the Free Exercise Clause of the First Amendment since the nineteenth century, city and state efforts to codify legal protections for LGBTQ+ individuals in the mid-twentieth century birthed novel challenges. Private individuals who do not condone intimate same-sex relationships and/or gender non-conforming behavior, on religious grounds seek greater legal protection for the ability to refuse to offer goods and services to LGBTQ+ persons. Federal and state courts must determine how to resolve these …

A digital designer can promote sustainable …

Assessing The Impact Of Bicycle Infrastructure And Modal Shift On Traffic Operations And Safety Using Microsimulation, Katherine E. Lee

Master's Theses

A transportation system designed to prioritize the mobility of automobiles cannot accommodate the growing number of road users. The Complete Streets policy plays a crucial part in transforming streets to accommodate multiple modes of transportation, especially active modes like biking and walking. Complete streets are referred to as streets designed for everyone and enable safety and mobility to all users. A strategy of complete streets transformation is to connect isolated complete street segments to form a complete network that improves active mobility and public transit ridership.

This research assessed the impact of efficiently and equitably connecting and expanding the biking …

Deception-Based Knowledge In Indigenous And Scientific Societies American Indian Tricksters And Experimental Research Designs, Yancey Orr, Raymond Orr

Environmental Science and Policy: Faculty Publications

The emerging movement to decolonize the sciences, social sciences, and humanities has emphasized the differences between Indigenous and Western scientific ways of knowing. Paradoxically, emphasizing the difference between these systems has also been the principle undergirding modern science’s claim to being a uniquely valid means of knowledge creation. Yet as each approach focused solely on contrasting Indigenous and scientific ways of knowing, potential similarities between these knowledge systems may have been ignored. One such oversight is the use of deception by each system, which is central to experimental research designs in the social and psychological sciences, and in American Indian …

Framing Human Action In Physics: Valid Reconstruction, Invalid Reduction, Shabnam Mousavi, Shyam Sunder

Cowles Foundation Discussion Papers

We propose framing human action in physics before reaching to biology and social sciences, rearranging the order of their usual deployment. As an example, consider efforts to model altruism that start in a frame of psychological or social attributes such as reciprocity, empathy, and identity. Evolutionary roots might also be used by appeal to survival of the species from biology. Only then the modeler abstracts to work on notations, and to establish relationships using mathematical apparatus from physics. This top-down deployment of principles from various scientific disciplines has generated a body of coherent models, partially generalizable theories, and disagreements. In …

Impact Of Gamification On An Online Middle School Classroom, Jeremy R. Hein

Masters Theses

Gamification is defined as the use of game elements in non-game contexts. The gamified element explored in this thesis is a leaderboard with various forms of engagement being tabulated. This study investigates the impact a leaderboard has on the behavioral engagement of an online middle school classroom. Research has revealed that elements of gamification can increase engagement but there is a gap in research that focuses solely on a leaderboard as an intervention to increase engagement. Also missing from the literature were studies conducted in middle school settings. The study presented in this thesis addresses these limitations and provides value …

Understanding Institutional Life-Cycle And Sustainability Of Co-Operative Model: A Case Study Of Campco, India, Amalendu Jyotishi, Deepika M.G.

The Indonesian Journal of Socio-Legal Studies

Co-operative movement in India has a long-standing contribution in the growth of business, agriculture and allied activities. One such cooperative movement in India is the Central Arecanut and Cocoa Marketing and Processing Co-operative Limited (CAMPCO) which was initiated with a joint cooperation between the states of Karnataka and Kerala to create an organized market structure for the two plantation crops namely Arecanut and Cocoa in the backdrop of falling market price of these crops. CAMPCO is an interesting co-operative movement, worth investigating in terms of its evolution, challenges, growth and diversification. The paper tries to examine the factors responsible for …

The Supercooling Responses Of The Solitary Bee Osmia Excavata (Hymenoptera: Megachilidae) Under The Biological Stress Of Its Brood Parasite, Sapyga Coma (Hymenoptera: Sapygidae), Zhuo Yan, Lina Wang, Gadi V.P. Reddy, Shimin Gu, Xingyuan Men, Yunli Xiao, Jianwei Su, Feng Ge, Fang Ouyang

Faculty Publications

(1) Background: Many insects have evolved different strategies to adapt to subzero temperatures and parasites, but the supercooling response of pollinator populations under the brood parasitism pressure has not been sufficiently investigated. (2) Methods: This study assessed the supercooling traits (supercooling points, fresh weight and fat content) of the solitary bee Osmia excavata Alfken and its brood parasite, Sapyga coma Yasumatsu & Sugihara. We measured 4035 samples (3025 O. excavata and 1010 S. coma, one individual as one sample) and discovered the super-cooling traits relations between solitary bee and brood parasite. (3) Results: Significant differences in the supercooling points were …

Identifying Potential Drivers Of Distribution Patterns Of Invasive Corbicula Fluminea Relative To Native Freshwater Mussels (Unionidae) Across Spatial Scales, Taylor E. Kelley, Garrett W. Hopper, Irene Sánchez González, Jamie R. Bucholz, Carla L. Atkinson

Faculty Publications

This study aimed to identify the importance of ecological factors to distribution patterns of the invasive Clam (Corbicula fluminea) relative to native mussels (family: Unionidae) across seven rivers within the Mobile and Tennessee basins, Southeast United States. We quantitatively surveyed dense, diverse native mussel aggregations across 20 river reaches and estimated mussel density, biomass, and species richness along with density of invasive C. fluminea (hereafter Corbicula). We measured substrate particle size, velocity, and depth in quadrats where animals were collected. Additionally, we characterized reach scale environmental parameters including seston quantity and quality (% Carbon, % Nitrogen, % Phosphorous), water chemistry …

Med12 Regulates Human Adipose-Derived Stem Cell Adipogenesis And Mediator Kinase Subunit Expression In Murine Adipose Depots, Sree Venigalla, Joseph Straub, Onyekachi Idigo, Caroline Rinderle, Jacqueline M. Stephens, Jamie J. Newman

Division of Basic Science Faculty Publications

The mediator kinase module plays a critical role in the regulation of transcription during metabolic processes. Here we demonstrate that in human adipose-derived stem cells (hASCs), kinase module subunits have distinct mRNA and protein expression profiles during different stages of adipogenesis. In addition, siRNA-mediated loss of MED12 results in decreased adipogenesis as evident through decreased lipid accumulation and decreased expression of PPARγ, a master regulator of adipogenesis. Moreover, the decrease in adipogenesis and reduced PPARγexpression are observed only during the early stages of MED12 knockdown. At later stages, knockdown of MED12 did not have any significant effects on adipogenesis or …

The Counterbalancing Effects Of Energy Expenditure On Body Weight Regulation: Orexigenic Versus Energy-Consuming Mechanisms, Paolo Piaggi, Alessio Basolo, Corby K. Martin, Leanne M. Redman, Susanne B. Votruba, Jonathan Krakoff

Clinical Research Faculty Publications

Objective: Weight change is a dynamic function of whole-body energy balance resulting from the interplay between energy intake and energy expenditure (EE). Recent reports have provided evidence for the existence of a causal effect of EE on energy intake, suggesting that increased EE may drive overeating, thereby promoting future weight gain. This study investigated the relationships between ad libitum energy intake and 24-hour EE (24-h EE) in sedentary conditions versus long-term, free-living weight change using a mediation analysis framework. Methods: Native American individuals (n = 61, body fat by dual-energy x-ray absorptiometry: 39.7% [SD 9.5%]) were admitted to the clinical …

Tears & Ashes: Three Ways Of Looking At The Recent Wildfires In The West, Vincent J. Miller

Theology and Religious Studies Faculty Publications

As life in the Anthropocene unfolds ever more rapidly, what were once called “biblical” disasters — fires, floods, locusts, and whirlwinds — have become a daily reality. We watch anxiously as catastrophes occur, at least as much as our screens allow, but still go about our business: reading the next story in our newsfeed or wading into half-flooded subways to avoid being late for work. The problem we face is more difficult than mere inattentiveness: we need to cultivate a way of seeing adequate to the changed world being revealed in these catastrophes.

Properties Of Rent: The Political Economy Of Urban Villages In Delhi, Sushmita Pati

Books

We live in cities whose borders have always been subject to expansion. What does such transformation of rural spaces mean for cities and vice-versa? This book looks at the spatial transformation of villages brought into the Delhi's urban fray in the 1950s. As these villages transform physically; their residents, an agrarian-pastoralist community - the Jats - also transform into dabblers in real estate. A study of two villages - Munirka and Shahpur Jat - both in the heart of bustling urban economies of Delhi, reveal that it is 'rent' that could define this suburbanisation. 'Bhaichara', once a form of land …

Emergent Intra-Pair Sex Differences And Organized Behavior In Pair Bonded Prairie Voles (Microtus Ochrogaster), Liza E. Brusman, David S.W. Protter, Allison C. Fultz, Maya U. Paulson, Gabriel D. Chapel, Isaiah O. Elges, Ryan T. Cameron, Annaliese K. Beery, Zoe R. Donaldson

Psychology: Faculty Publications

In pair bonding animals, coordinated behavior between partners is required for the pair to accomplish shared goals such as raising young. Despite this, experimental designs rarely assess the behavior of both partners within a bonded pair. Thus, we lack an understanding of the interdependent behavioral dynamics between partners that likely facilitate relationship success. To identify intra-pair behavioral correlates of pair bonding, we used socially monogamous prairie voles (Microtus ochrogaster) and tested both partners using social choice and non-choice tests at short- and long-term pairing timepoints. Females developed a preference for their partner more rapidly than males, with preference driven by …

Sex Differences In The Reward Value Of Familiar Mates In Prairie Voles, Daniel M. Vahaba, Emily R. Halstead, Zoe R. Donaldson, Todd H. Ahern, Annaliese K. Beery

Psychology: Faculty Publications

The rewarding properties of social interactions facilitate relationship formation and maintenance. Prairie voles are one of the few laboratory species that form selective relationships, manifested as “partner preferences” for familiar partners versus strangers. While both sexes exhibit strong partner preferences, this similarity in outward behavior likely results from sex-specific neurobiological mechanisms. We recently demonstrated that in operant trials, females worked hardest for access to familiar conspecifics of either sex, while males worked equally hard for access to any female, indicating a sex difference in social motivation. As tests were performed with one social target at a time, males might have …

Pervasive Neglect Of Sex Differences In Biomedical Research, Irving Zucker, Brian J. Prendergast, Annaliese K. Beery

Psychology: Faculty Publications

Females have long been underrepresented in preclinical research and clinical drug trials. Directives by the U.S. National Institutes of Health have increased female participation in research protocols, although analysis of outcomes by sex remains infrequent. The long-held view that traits of female rats and mice are more variable than those of males is discredited, supporting equal representation of both sexes in most studies. Drug pharmacokinetic analysis reveals that, among subjects administered a standard drug dose, women are exposed to higher blood drug concentrations and longer drug elimination times. This contributes to increased adverse drug reactions in women and suggests that …

Pando Aspen 2021 Remeasure, Paul C. Rogers

Browse all Datasets

Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers. This is the first trend assessment of this threatened iconic forest using a vital indicators approach. I examined 64 plots using 19 indicators to determine current conditions. Findings show that a genetically uniform Pando is 'breaking up' because of herbivory fencing. Initial …
