So, our city’s shrinking—Now what?
Effective per capita municipal expenditures correlated with population changes

Policymakers often overlook the challenges faced by shrinking small and medium-sized cities. Yet, keeping these cities sustainable is crucial for many urban stakeholders. Unfortunately, the methods that have succeeded in large cities cannot be unilaterally applied to combat this issue. This suggests that a research gap on effective urban management in small and medium-sized cities exists.
Dr. Haruka Kato, a junior associate professor at Osaka Metropolitan University, examined the types of municipal expenditures that correlated with population changes in small and medium-sized cities. The research design used cross-sectional studies from 2007 to 2022 of all small and medium-sized cities in Japan. The nonlinear relationship between data was analyzed using the eXtreme Gradient Boosting algorithm.
The results revealed that 1288 cities were shrinking, accounting for 82.56% of all small and medium-sized cities in Japan. Further, this study identified the types of per capita municipal expenditures that correlated with population change, which were often associated with welfare expenditures. Specifically, the population grew in cities that increased per capita expenditures on children and decreased those on welfare recipients and the older population. Additionally, city planning expenditures were also effective, but only in the maintenance and construction of streets.
“In recent years, urban policymakers have adopted an urban management perspective. With limited financial resources, policymakers must decide what and how much to invest in citizens,” said Dr. Kato. “Our research clearly suggests prioritizing child welfare expenditures as a key strategy to sustain populations in small and medium-sized cities.”
The findings were published in the Journal of Urban Management.

A new systematic review has found that parents and other child caregivers who have alcohol-related diagnoses are twice as likely to maltreat children in their care than parents and caregivers with no alcohol-related diagnoses. ‘Alcohol-related diagnoses’ included alcohol-related hospitalisation, alcohol-related service use, or a history of clinically determined alcohol dependence. ‘Child maltreatment’ included physical, psychological, emotional and sexual abuse; neglect; and other types of maltreatment such as harsh parenting.
The study pooled the results from twelve studies of child maltreatment. All were cohort studies in high-income countries: three in ...

Imagine a crocodile built like a greyhound — that’s a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that’s what paleontologists thought, until they began finding strange, fossilized teeth in the Caribbean.
“The first question that we had when these teeth were found in the Dominican Republic and on other islands in the Caribbean was: What are ...

Scientists at the Smithsonian Tropical Research Institute (STRI) found that the fringe-lipped bat, known to eavesdrop on frog and toad mating calls to find its prey, learns to distinguish between palatable and unpalatable frogs and toads through experience. The findings, published April 29 in the Proceedings of the Royal Society B, provide the first evidence that eavesdropping predators fine-tune their hunting cues over the course of their development.
To source their food, some predators eavesdrop on calls emitted by prey. Fringe-lipped bats, which range from Panama to Brazil, are some of the most skilled eavesdroppers in the world: They are attuned to the sexual advertisement ...

The likelihood of a pedestrian or cyclist being fatally injured is 44% higher if they are hit by a sports utility vehicle (SUV) or light truck vehicle (LTV) compared with smaller passenger cars, new research shows. For children there is an even larger effect, with a child hit by a SUV or LTV being 82% more likely to be killed than a child hit by a passenger car.
As part of a new analysis of existing studies, researchers at the London School of Hygiene & Tropical Medicine (LSHTM) and Imperial College London gathered real-world collision data from over 680,000 collisions from the last 35 years. They compared the severity of injuries suffered by pedestrians ...

Researchers at Amsterdam UMC have developed a new diagnostic test that can quickly and accurately diagnose bacterial meningitis. The test measures the CRP protein in cerebrospinal fluid, a protein that is already often tested in blood to detect bacterial infections. Research shows that elevated CRP in cerebrospinal fluid is a very reliable indicator of bacterial meningitis. Currently it often takes a long time before meningitis is diagnosed, which delays the start of adequate treatment. The study is published today in The Lancet Regional Health Europe.

Nearly two-thirds of adults in the U.S. have experienced some form of in-person exposure to gun violence, according to a national study by Rutgers researchers tracking racial disparities in direct and media-based experiences.
This study, published in the Lancet Regional Health – Americas, examines how frequently U.S. adults are exposed to gun violence, both in person and through media, based on data from a nationally representative sample. It looks at who is most affected based on their race, income, and the neighborhoods they live in.
Researchers surveyed 8,009 adults throughout the U.S. to find out how often people experience gun violence, whether directly (such ...

Cholera kills thousands of people and infects hundreds of thousands every year—and cases have spiked in recent years, leaving governments with an urgent need to find the best ways to control outbreaks.
Current public health guidelines discourage treating cholera with antibiotics in all but the most severe cases, to reduce the risk that the disease will evolve resistance to the best treatments we have.
But recent disease modeling research from University of Utah Health challenges that paradigm, suggesting that for some cholera outbreaks, prescribing antibiotics ...

A higher tax on cigarettes in low and middle-income countries can help to reduce child mortality, especially amongst the poorest children, a new study led by researchers at Karolinska Institutet and published in The Lancet Public Health suggests.
The World Health Organisation (WHO) recommends a tax of at least 75 percent on the retail price of cigarettes, but most countries impose a much lower tax than that.
“If all 94 countries included in the study had raised their cigarette tax to the level recommended by the WHO, the lives of over 280,000 children could potentially have been saved in a single year,” says Márta Radó, principal investigator at ...

Exercise can counter the detrimental effects of cancer treatment, such as heart and nerve damage and brain fog, suggests an overarching review of the existing pooled data analyses of the most recent research, published online in the British Journal of Sports Medicine.
Exercise also seems to boost psychological wellbeing and overall quality of life, lending weight to its routine inclusion in treatment protocols for the disease, say the researchers.
Several pooled data analyses of the available research have evaluated the impact of exercise on health outcomes in people with cancer, but significant gaps remain in our understanding, ...

Employing too few permanent nurses on hospital wards is linked to longer inpatient stays, readmissions, patient deaths, and ultimately costs more in lives and money, finds a long term study published online in the journal BMJ Quality & Safety.
Redressing the balance is cost-effective, saving an estimated £4728 for each year of healthy life gained per patient, but not if temporary agency staff are used to plug the gaps, the findings indicate.
Inadvertent understaffing–through unfilled vacancies–or deliberate–through cost cutting ...
