Book Review: Thanks For Your Service: The Causes And Consequences Of Public Confidence In The Us Military, James "Andy" Nichols

Parameters Bookshelf – Online Book Reviews

Author: Christian Nikolaus Braun

Reviewed by Lieutenant Colonel James “Andy” Nichols, US Army War College class of 2023

Lieutenant Colonel James “Andy” Nichols provides a thoughtful review of Duke University professor Peter D. Feaver’s book on the reasons for—and proposed ways to maintain—the “high public confidence” that the US military has experienced since 2001. Nichols overviews Feaver’s research methodology and policy recommendations, providing potential readers useful praise of the book’s merits—particularly Feaver’s “discussions surrounding politicization (party) and public pressure”—and some critiques, namely that the policy recommendations are “underdeveloped.” Nichols concludes that “[t]he text advances policy discussions on public confidence in …

Synthetic Biology Enablement: From Academic Development To Industrial Transformation, Yan Xiong, Xueqing Ma, Daming Chen, Xiao Liu, Guoping Zhao

Bulletin of Chinese Academy of Sciences (Chinese Version)

Synthetic biology revolutionizes the comprehension of life systems from an engineering perspective, employing a “bottomup” approach in life science research. It adopts an iterative research paradigm of “design-build-test-learn” in life science research and creates engineered new life systems grounded in genomics and systems biology. This provides a new pathway of “from creation to understanding” for life sciences, departing from the traditional reductionist research strategy of “study the whole to understand the parts” and opening up a new culture of “building to understand” the essence of life. Additionally, synthetic biology elevates existing biotechnologies previously based on “simulating natural processes” and “genetic …

Bikeability Disparities In Orange County, California: Intersection Of Place And Demographics, Jeanette Gritton, Maria Cristina Martinez, Georgiana Bostean, Megan Thiele Strong

Sociology Faculty Articles and Research

Active transportation modes such as walking and biking are gaining popularity for their extensive health and environmental benefits, yet scholars know little about how place-based accessibility varies by area sociodemographic composition. This study is among the first to examine sociodemographic disparities (by both race and socioeconomic status) in bikeability while allowing for heterogeneity in disparities. Consideration of bikeability disparities is particularly critical within the framework of urban planning concepts that promote equitable accessibility and reduced dependency on automobiles, such as the 15-minute city. Geographically Weighted Regressions examined associations between census tract-level bikeability (using an index that combines five components), socioeconomic …

Taser Use In Law Enforcement: Examining Effectiveness, Medical Consequences, And Ideal Scenarios, Benjamin Smyers

Themis: Research Journal of Justice Studies and Forensic Science

The methods police officers use to detain resisting subjects have changed over time. One addition to their methods is the Thomas A. Swift Electric Rifle (TASER), which hinders subjects using electric shock. This paper examines the effectiveness of the TASER, the potential risk of injury for suspects, and scenarios where its use is most likely to succeed. Since its adoption, the TASER has reduced the likelihood of injury to officers and suspects and is more effective against heavy-set and intoxicated individuals. Although extremely unlikely to result in death, injuries are more likely when used against mentally disturbed people and in …

“Kenough”: What Greta Gerwig’S Barbie Film Has To Teach Us About Social And Distributive Justice Related To Masculinity And Positive Masculine Qualities, B.D. White

Themis: Research Journal of Justice Studies and Forensic Science

Beyond Barbie’s feminist messages, the academy award winning film gently nudges the viewer to consider “male fragility,” prompting a deeper exploration of male role norms (MRNs) and masculine expression among cisgendered, American men. Conforming to these norms is linked to societal issues such as higher rape myth acceptance, homophobia, transphobia, and gender role strain. This analysis underscores the necessity of challenging traditional male norms for a more just society. This paper redefines MRNs, arguing that they are not a blueprint for healthy masculinity but a distortion rooted in a culture that restricts men's experiences. Norms are scrutinized, offering definitions, social …

The Limitations And Future Of Isotope Analysis In Forensic Anthropology, Kris Weller

Themis: Research Journal of Justice Studies and Forensic Science

This research paper will discuss the applications of isotope analysis in forensic anthropology, focusing on the limitations of this technique and its potential future uses. Isotope analysis is based on the principle that isotope ratios vary across geographic regions and that humans incorporate those unique isotope ratios into their bodies when they eat and drink. Forensic anthropology uses isotope analysis to determine a decedent’s approximate region of origin or residence. It is especially in cases where the remains are partially or highly decomposed, and when other avenues of investigation have been exhausted. In its current form, the applications of isotope …
