Neurology and psychiatry have long been divided as subspecialities of medicine. However, the symptom overlap in central nervous system illness is unmistakable. Medical science has evolved, necessitating a neuropsychiatric approach that is more comprehensive. This editorial briefly outlines the history of neurology and psychiatry and the movement towards a new paradigm.

I, Mary Caputi, was humbled and honored to be offered the editorship of Politics & Gender, a position that I filled between 2016–19. With my hard-working associate editors Sun Young Kwak, Steve Gonzales, and Timothy Kaufman-Osborn, we strove to build upon the journal’s already strong reputation as an agenda-setting academic publication that offers cutting-edge scholarship in all areas of gender studies. Because the relationship between “politics and gender” is so rich and complex, we tried to faithfully represent the depth and variety of interplay in our scholarly articles, Critical Perspectives contributions, Special Issues, and our choice of books to be reviewed. As a team, the task of editing the journal sent us on an enlightening journey that proved both challenging and educational. Throughout my tenure, I learned a great deal about my own field of contemporary feminist theory, and about how gender is studied in other subfields of political science and other academic disciplines across the university.

Historical narratives can satisfy basic individual psychological needs. However, an over-reliance on a group's past can marginalize those who think differently – thus, homogenizing the culture and stifling creativity. By revising narratives to balance the power of collective narratives with the richness of individuality, we foster groups that encourage varied identities.

The UK has seen an outbreak of riots after the death of three children in a knife attack. Misinformation about the suspect's heritage and religion was spread by social media, which was then used to incite violence and racism resulting in damage to property, terror and injuries. We put forward arguments that this was an extremist act and draw on the literature on terrorism, extremism and identity to put forward a deeper analysis of how this happened and what can be done to prevent future riots. We bring an interdisciplinary perspective drawing on research from social, cultural, psychological and political perspectives.

The COVID-19 pandemic highlighted gaps in infection control knowledge and practice across health settings nationwide. The Centers for Disease Control and Prevention, with funding through the American Rescue Plan, developed Project Firstline. Project Firstline is a national collaborative aiming to reach all aspects of the health care frontline. The American Medical Association recruited eight physicians and one medical student to join their director of infectious diseases to develop educational programs targeting knowledge gaps. They have identified 5 critical areas requiring national attention.

In this article Amy Kaufman, Head Law Librarian at Queen's University, Kingston, Canada, examines what role Canadian law libraries can take in responding to the findings of the Truth and Reconciliation Commission (TRC) Report in 2015, which examined the treatment of Aboriginal people in the country throughout its history, and its Calls to Action.

Bioturbation can increase time averaging by downward and upward movements of young and old shells within the entire mixed layer and by accelerating the burial of shells into a sequestration zone (SZ), allowing them to bypass the uppermost taphonomically active zone (TAZ). However, bioturbation can increase shell disintegration concurrently, neutralizing the positive effects of mixing on time averaging. Bioirrigation by oxygenated pore-water promotes carbonate dissolution in the TAZ, and biomixing itself can mill shells weakened by dissolution or microbial maceration, and/or expose them to damage at the sediment–water interface. Here, we fit transition rate matrices to bivalve age–frequency distributions from four sediment cores from the southern California middle shelf (50–75 m) to assess the competing effects of bioturbation on disintegration and time averaging, exploiting a strong gradient in rates of sediment accumulation and bioturbation created by historic wastewater pollution. We find that disintegration covaries positively with mixing at all four sites, in accord with the scenario where bioturbation ultimately fuels carbonate disintegration. Both mixing and disintegration rates decline abruptly at the base of the 20- to 40-cm-thick, age-homogenized surface mixed layer at the three well-bioturbated sites, despite different rates of sediment accumulation. In contrast, mixing and disintegration rates are very low in the upper 25 cm at an effluent site with legacy sediment toxicity, despite recolonization by bioirrigating lucinid bivalves. Assemblages that formed during maximum wastewater emissions vary strongly in time averaging, with millennial scales at the low-sediment accumulation non-effluent sites, a centennial scale at the effluent site where sediment accumulation was high but bioturbation recovered quickly, and a decadal scale at the second high-sedimentation effluent site where bioturbation remained low for decades. Thus, even though disintegration rates covary positively with mixing rates, reducing postmortem shell survival, bioturbation has the net effect of increasing the time averaging of skeletal remains on this warm-temperate siliciclastic shelf.

Late-onset sepsis (LOS) in the neonatal intensive care unit (NICU) causes significant morbidity and mortality, yet guidance on empiric management is limited. We surveyed NICUs across Canada and the United States regarding their empiric antimicrobial regimens for LOS, thereby identifying large practice variations and high rates of empiric vancomycin use.

As a wave of backsliding has swept across both new and established democracies, scholars have sought to identify formal and informal institutions that can act as guardrails of democracy. But while informal norms, party structures, and formal institutions such as separation of powers have all been singled out as potential bulwarks against democratic backsliding, the literature has had less to say about what role, if any, federalism might play in stopping democracies from sliding into autocracy. While some constitutional designers and scholars have argued that federalism can help to prevent the emergence of a national tyranny, most contemporary research has emphasized the damaging effects federalism can have on democracy. In this article, we assess the relationship between federalism and threats posed by national rulers, with quantitative analysis of that relationship in countries around the world and with structured, focused comparative case studies in the United States, Brazil, Venezuela, and India. Our quantitative analysis finds no systematic relationship between federalism and backsliding, while our comparative case studies support our argument that federalism is only likely to serve as a bulwark against autocratic threats posed by national rulers under a limited set of conditions.

Tophets are Phoenician and Punic sanctuaries where cremated infants and children were buried. Many studies focus on the potentially sacrificial nature of these sites, but this article takes a different approach. Combining osteological analysis with a consideration of the archaeological and wider cultural context, the authors explore the short life-courses and mortuary treatments of 12 individuals in the tophet at the Neo-Punic site of Zita, Tunisia. While osteological evidence suggests life at Zita was hard, and systemic health problems may have contributed to the deaths of these individuals, their mortuary rites were attended to with care and without concrete indication of sacrifice.

We provide the first evidence that firms, not just voters, are gerrymandered. We compare allocations of firms in enacted redistricting plans to counterfactual distributions constructed using simulation methods. We find that firms are over-allocated to districts held by the mapmakers’ party when partisans control the redistricting process; maps drawn by courts and independent commissions allocate firms more proportionately. Our results hold when we account for the gerrymandering of seats: fixing the number of seats the mapmakers’ party wins, they obtain more firms than expected in their districts. Our research reveals that partisan mapmakers target more than just voters, shedding new light on the link between corporate and political power in the United States and opening new pathways for studying how mapmakers actually draw district boundaries.

The unbridled positivity toward curiosity and creativity may be excessive. Both aid species survival through exploration and advancement. These beneficial effects are well documented. What remains is to understand their optimal levels and contexts for maximal achievement, health, and well-being. Every beneficial element to individuals and groups carries the potential for harm – curiosity and creativity included.

While presidents frequently create new policies through unilateral power, empirical scholarship generally focuses on executive orders and overlooks other categories of directives. We introduce data on more than 50,000 unilateral directives issued between 1877 and 2020 and use machine learning techniques to characterize their substantive importance and issue areas. Our measures reveal significant increases in unilateral activity over time, driven largely by increases in foreign affairs and through the substitution of memoranda for executive orders. We use our measures to formally evaluate the historical development of the unilateral presidency and reassess theoretical claims about public opinion and unilateral power. Our research provides new evidence about variation in the use of presidential authority and opens new avenues for empirical inquiry.

Northern Arizona University, Flagstaff, Arizona, USA, recently installed a MIni CArbon DAting System (MICADAS) with a gas interface system (GIS) for determining the 14C content of CO2 gas released by the acid dissolution of biogenic carbonates. We compare 48 paired graphite, GIS, and direct carbonate 14C determinations of individual mollusk shells and echinoid tests. GIS sample sizes ranged between 0.5 and 1.5 mg and span 0.1 to 45.1 ka BP (n = 42). A reduced major axis regression shows a strong relationship between GIS and graphite percent Modern Carbon (pMC) values (m = 1.011; 95% CI [0.997–1.023], R2 = 0.999) that is superior to the relationship between the direct carbonate and graphite values (m = 0.978; 95% CI [0.959-0.999], R2 = 0.997). Sixty percent of GIS pMC values are within ±0.5 pMC of their graphite counterparts, compared to 26% of direct carbonate pMC values. The precision of GIS analyses is approximately ±70 14C yrs to 6.5 ka BP and decreases to approximately ±130 14C yrs at 12.5 ka BP. This precision is on par with direct carbonate and is approximately five times larger than for graphite. Six Plio-Pleistocene mollusk and echinoid samples yield finite ages when analyzed as direct carbonate but yield non-finite ages when analyzed as graphite or as GIS. Our results show that GIS 14C dating of biogenic carbonates is preferable to direct carbonate 14C dating and is an efficient alternative to standard graphite 14C dating when the precision of graphite 14C dating is not required.
