Mass shooting lockdown drills help schoolchildren feel safer, US study suggests

Findings showing those already exposed to violence feel safer, contradict previous research conclusions

2024-02-23
(Press-News.org) Lockdown drills, practiced to help prepare children for shooting incidents at school, make those who have been exposed to violence feel safer – a new study of thousands of students in the US indicates. 

 

The finding, reported in a new peer-reviewed paper published in the Journal of School Violence, contradicts claims that the drills traumatize children, without making them feel safer. 

 

Ensuring that students feel safe – and are safe – in schools is essential for them to learn and thrive, explains researcher Dr Jaclyn Schildkraut, Executive Director of the Regional Gun Violence Research Consortium at the Rockefeller Institute of Government in the US. 

 

One safety measure that’s widely practiced in the US is lockdown drills. The drills, which are carried out at almost all public schools, involve locking classroom doors, turning off the lights, staying out of sight, and remaining quiet. 

 

They were introduced after the Columbine High School massacre of 1999, in which two teenagers shot dead 12 of their fellow pupils and a teacher and wounded 24 others.   

 

Lead author, Dr Schildkraut joined colleagues from the University at Buffalo, University at Albany, and Syracuse University to explore how lockdown drills affect perception of school safety in children who have been exposed to violence.   

 

While mass shootings are rare, a nationwide survey found that almost half of school-aged children in the US had been exposed to bullying or violence in the previous year, while at school.   

 

“It is important for students to perceive their schools to be safe because it can impact how they function as students generally,” says Dr Schildkraut – a national expert on mass shootings research. 

 

“For instance, not feeling safe at school can lead to anxiety, depression, lowered academic performance and missing school.  

 

“In addition, not feeling safe at school can lead students to have increased perceptions of risk –thinking they are more likely to be harmed at school than they actually are – or be adversely impacted by practices designed to keep them safe, like lockdown drills.” 

 

For the study, students in 5th Grade and above in a large urban school district in New York State were asked to fill in a survey about how safe they felt at school and how prepared they were for lockdowns and other emergencies. 

 

The students were also surveyed on their exposure to violence.  They were asked if they had: seen or heard of someone bring gun to school; seen someone bring a knife to school; been involved in or seen one or more physical fights; been bullied or seen someone else being bullied. 

 

The students then participated in a lockdown drill, before filling out the survey again.   

 

Several months later, they were given training on how to respond to emergencies.  They then took part in a second lockdown drill and filled in the survey for a third time. 

 

Some 8,627 surveys were completed by students with an average age of 14. The males and younger children tended to feel safer than females and other children.  

 

The respondents had been exposed to 1.9 types of violence, on average. The most common forms were witnessing fights and witnessing bullying. 

 

Those who had been exposed to violence felt less safe at school than others and the more types of violence they’d been exposed to, the less safe they felt.  However, taking part in the drills and training seemed to, at least in part, mitigate the harmful effects of the exposure to violence. 

 

Dr Schildkraut says: “Participating in drills may be a way to help students who have been exposed to violence feel safer in schools.  

 

“This finding provides policymakers with direct empirical evidence against calls for lockdown and other safety drills to be abandoned on the basis that they traumatize children without making them feel safer.” 

 

Students who had been exposed to violence felt less prepared for emergencies than others but the respondents as a whole felt more prepared for emergencies after taking part second drill than at the start of the study.  

 

Dr Schildkraut says: “The main purpose of emergency preparedness drills, including lockdowns, is for individuals to build muscle memory, which enables them to respond correctly in stressful situations without conscious effort. 

 

“And so, it is possible that the confidence gained from taking part lockdown drills may help to offset the negative effects of exposure to violence over time.” 

 

She adds that more research is needed to determine whether their findings apply to children in more rural areas, where levels of violence may be lower.  Similarly, further work is needed to confirm that the results apply to lockdown drills other than the one used in the study.   

 

Other limitations include the inability to prove causation and to track individual students’ responses over time.  

 

The authors conclude: “When lockdown drills are conducted correctly they can offer unintended benefits, such as offsetting harmful effects of exposure to violence, in addition to helping to prepare students for emergencies.” 

 

They also urge policymakers to do more to tackle violence in schools. “All students deserve a safe, supportive and healthy learning environment in which they can thrive as students and as individuals,” says Dr Schildkraut.

Using mussels and silkworm cocoons to stop organ bleeding

Using mussels and silkworm cocoons to stop organ bleeding
2024-02-23
In recent news, there has been a case where a patient experienced pain due to a surgical procedure involving sutures, resulting in the unintended presence of gauze within the patient's body. Gauze is typically employed to control bleeding during medical interventions, aiding in hemostasis. However, when inadvertently left in the body, it can lead to inflammation and infection. Addressing this issue, recent research has been published by researchers focusing on a hemostatic agent derived from mussels and silkworm cocoons. This hemostatic agent has garnered attention in the academic community due to its efficacy in clotting blood and its safety within ...

New research reveals how cancer hijacks immune cells to promote tumour growth

2024-02-23
A new research study led by A*STAR.Singapore Immunology Network (A*STAR.SIgN) has found that neutrophils—one of the most abundant white blood cells in our body—change drastically in certain cancers, adopting a new function whereby they promote tumour growth. By carefully studying neutrophils as soon as they enter the tumour, scientists from A*STAR.SIgN also uncovered ways to accurately differentiate tumour-promoting neutrophils from normal neutrophils present in the rest of the body. Neutrophils play important and irreplaceable roles in fighting infections, ...

Gene regulatory networks (GRNs) depict the regulatory mechanisms of genes within cellular systems as a network, offering vital insights for understanding cell processes and molecular interactions that determine cellular phenotypes. Transcriptional regulation, a prevalent type for regulating gene expression, involves the control of target genes (TGs) by transcription factors (TFs). One of the major challenges in inferring GRNs is to establish causal relationships, rather than just correlation, among the various components ...

Image-sentence retrieval task aims to search images for given sentences and retrieve sentences from image queries. The current retrieval methods are all supervised methods that require a large number of annotations for training. However, considering the labor cost, it is difficult to re-align large amounts of multimodal data in many applications (e.g., medical retrieval), which results in unsupervised multimodal data. To solve the problem, a research team led by Yang YANG published their new research on 15 Feb 2024 in Frontiers of Computer Science co-published by Higher Education Press and ...

A novel deep learning modeling approach guided by mesoscience—MGDL

A novel deep learning modeling approach guided by mesoscience—MGDL
2024-02-23
Deep learning modeling that incorporates physical knowledge is currently a hot topic, and a number of excellent techniques have emerged. The most well-known one is the physics-informed neural networks (PINNs). PINN integrates the residuals of the system’s governing partial differential equations (PDEs) and the initial value/boundary conditions into the loss function, thus the resulting model satisfies the constraints of the physical laws represented by the PDEs. However, PINN cannot work if equations among the key physical quantities of the system have not been established. To ...

Improving social symptoms of depression with a common anesthetic

Improving social symptoms of depression with a common anesthetic
2024-02-23
Osaka, Japan – Well-being is important for everyone, especially when we feel lonely or isolated. Depression is a serious challenge for many people and finding an effective solution is key. In a recent study published in Molecular Psychiatry, researchers from Osaka University used a mouse model of depression to reveal that one form of ketamine (a common anesthetic) in low doses can improve social impairments by restoring functioning in a specific brain region called the anterior insular cortex. Ketamine is often used at low doses to treat depression, but its actions in the brain remain relatively unclear. Generally, ketamine refers to a mix of two different forms of ketamine: ...

Killer instinct drove evolution of mammals’ predatory ancestors

Killer instinct drove evolution of mammals’ predatory ancestors
2024-02-23
The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers at the University of Bristol and the Open University suggest. The forerunners of mammals ruled the Earth for about 60 million years, long before the origin of the first dinosaurs. They diversified as the top predators on land between 315–251 million years ago. Researchers studied the jaw anatomy and body size of carnivorous synapsids, using these traits to reconstruct the likely feeding habits of these ancient predators and chart their ecological ...

Diversifying data to beat bias

2024-02-23
AI holds the potential to revolutionize healthcare, but it also brings with it a significant challenge: bias. For instance, a dermatologist might use an AI-driven system to help identify suspicious moles. But what if the machine learning model was trained primarily on image data from lighter skin tones, and misses a common form of skin cancer on a darker-skinned patient?   This is a real-world problem. In 2021, researchers found that free image databases that could be used to train AI systems to diagnose skin cancer contain very few images ...

Increased use of Paxlovid, the antiviral drug used to treat COVID-19, could prevent hundreds of thousands of hospitalizations and save tens of billions of dollars a year, according to a new epidemiological model published by researchers at The University of Texas at Austin. In fact, epidemiologists found that treating even 20% of symptomatic cases would save lives and improve public health. A 2023 National Institutes of Health study found that only about 15% of high-risk patients take Paxlovid when infected with COVID-19. Using a multiscale mathematical model based on ...
