Coordinated and Uncoordinated Punishment in a Team Investment Game
Get PDFCoordinated punishment occurs when punishment requires a specific number of punishers to be effective, otherwise, no damage will be inflicted on the target. While societies often rely on this punishment device, its benefits are unclear compared to uncoordinated punishment, where punishment decisions are substitutes. In this paper, we compare the efficacy of coordinated and uncoordinated punishment in a team investment game with two investors and one allocator. Our findings indicate that coordinated punishment results in higher levels of cooperation and reciprocity, as measured by the levels of joint investment and the return by allocators. Importantly, this does not translate into higher payoffs: investors use punishment more frequently when this is coordinated, which destroys the efficiency gains generated by the highest investment. In fact, our results suggest that the highest level of efficiency would be achieved if investors were not allowed to punish
What If We No Longer Call It DEI?
Get PDFThe persistent debate surrounding the term DEI reveals a broader dissatisfaction with its perceived limitations and the misunderstandings around its true meanings and concepts. As DEI initiatives face de-funding and positions are eliminated, there\u27s a risk of the term becoming diluted, associated more with performative gestures than genuine structural change.
This backlash against DEI also signifies a growing disappointment with \u27buzzword-driven\u27 approaches to diversity and inclusion, underscoring the need for a deeper understanding of equity and justice. In the middle of this critique, the idea of renaming DEI emerges as a means of revitalizing the discourse and re-centering efforts on inclusivity and social justice
And I Saw Sequences of Petals and Leaves: My Life as the One They Call Fibonacci
No full textIn this captivating historical novel, Daniele Struppa skillfully weaves a fictional autobiography, bringing Fibonacci to life with vivid details of his upbringing and adult years in Medieval Europe. As we explore the historical context of Fibonacci\u27s time, we delve into the intriguing aspects of a bygone era, painting a compelling picture of a man whose contributions to mathematics continue to resonate today.
From his groundbreaking work on congruent numbers to the famous numerical sequence that bears his name, the author invites readers to imagine the creative sparks that ignited Fibonacci\u27s mathematical innovations. When historical evidence is elusive, accuracy and passion are seamlessly combined, offering plausible scenarios grounded in documented facts. A meticulously crafted apparatus of notes distinguishes fact from fiction, providing readers with a clear guide to navigate this enthralling reconstruction of Fibonacci\u27s life.
Step into the medieval world of Leonardo Fibonacci, one of the most celebrated mathematicians in history, and discover the man behind the mathematical genius. Mathematicians and curious readers alike will appreciate the allure of Fibonacci\u27s mathematical brilliance.https://digitalcommons.chapman.edu/scs_books/1062/thumbnail.jp
The Moderating Effect of Socioeconomic Status and Walkability on the Efficacy of Physical Activity Interventions
Get PDFTo enable physical activity (PA) interventions to better tailor procedures to participant characteristics, we investigated the role of neighborhood socioeconomic status (SES) and walkability on the differential effectiveness of adaptive versus static activity goals (AG vs. SG) and immediate versus delayed (IR vs. DR) reinforcement in a PA trial.
Data was collected as a part of the WalkIT Arizona study, where healthy, inactive adults (n = 512) were instructed to wear an accelerometer daily for one year and were provided with daily goals for moderate-to-vigorous PA (MVPA). The intersection of goal types (adaptive and static) as well as reinforcement types (immediate and delayed) created four groups. Participants were block-randomized into one of four groups according to high/low neighborhood walkability and high/low neighborhood income. A linear regression model was fit to the data to predict mean daily MVPA based on the interaction of intervention condition and neighborhood walkability/income quadrant.
Each neighborhood walkability/SES quadrant level and intervention group interaction was statistically significant. In high walkability/high SES and low walkability/high SES groups, daily MVPA was highest for the AG/IR intervention and lowest for the SG/DR intervention (β = 12.18, p \u3c .001; β = 9.11, p \u3c .001, respectively). In the low walkability/low SES group, MVPA was also lowest for the SG/DR intervention but was highest for the SG/IR intervention. (β= 9.12, p \u3c .001). Results were qualitatively different in the high walkability/low SES group, where the most MVPA was seen for the SG/DR intervention, while the least was observed for AG/DR (β = 5.66 , p \u3c .001).
The results show that in a low-income/high-walkability environment, static goals and delayed reinforcement were most effective, which is the opposite of what was seen in other neighborhoods. These findings can be used to customize future physical activity interventions so that intervention strategies are most appropriate for participants’ demographic/environmental settings
Timely Dissonance : Anachronistic Music in Film
Get PDFMusic in film is used as a tool that can psychologically transport the viewer and alter their perception of a narrative. It is a highly influential aspect of the mise-en-scene and can influence both our reality and the fictional world in the film, depending on whether it is non-diegetic or diegetic. The elaborate soundscapes of period films typically utilize period accurate scores and soundtracks to embed the audience in the environment of a different age. However, this paper will examine ‘musical anachronism’ and the correlation between music and emotion through an analysis of films such as A Knight’s Tale (Brian Helgeland, 2001), Marie Antoinette (Sofia Coppola, 2006), and Jojo Rabbit (Taika Waititi, 2019), which deliberately incorporate anachronistic soundtracks to form a sense of temporal dissonance. These film examples create impossible, paradoxical situations as they explore how song choices can evoke familiar emotions from contemporary audiences. The use of anachronism is a stylistic choice that gives period films a new sense of resonance by eliciting certain emotions enhanced by the collaboration of visual and auditory senses. Using key scholars that include music and film psychology researcher Guido Heldt, and Professor of Philosophy, Dr. James O. Young, who focuses on art, language, and emotions, I will apply their findings along with many others in the field of music, film, and psychology to examine the correlation between music and emotion. This paper sheds light on the multifaceted role of soundtracks in shaping cinematic experiences, inviting audiences to reconsider the boundaries between historical accuracy and emotional responses in film
Pictorial Bionomics: Santa Ana River Record and Survey
No full textIntense conflict is unfolding in Southern California, and it runs right through our cities every day. It goes unnoticed by most, but its outcome will decide the future for humans and nature alike. This conflict is between human development and the natural majesty of our waterways. The foundation of Orange and surrounding areas is historic wetlands, which have caused massive flooding that destroys human lives and buildings. In response to this destruction, we have unleashed our own damage, paving entire sections of our rivers and erecting dams and levees wherever we can. Through this process we have successfully protected those in the vicinity, but at what cost? Rivers not only provide important habitats for wildlife, but also make for excellent recreation areas that humans can use to decompress. Our once beautiful rivers now parallel multi lane highways, are intersected by innumerable roads and bridges, and display record levels of contamination. Through this project I aim to raise awareness through documentation of the current state of the Santa Ana River and discover what changes we can make to better utilize this land in pursuit of a symbiosis that benefits humans and the environment alike. I will achieve this through advanced photography techniques alongside sociological and environmental research
