Perceptions of police using PPE during the pandemic - SFU study

Researchers at Simon Fraser University examine how different types of PPE impact public perception of police.

2021-01-13
(Press-News.org) A Simon Fraser University study on public perceptions of police officers wearing personal protective equipment (PPE) during the current pandemic finds that most PPE renders positive perceptions of police, while some equipment, including full-face respirator masks, may be viewed more negatively. The research was published January 9 in the Journal of Experimental Criminology.

Led by SFU criminology assistant professor Rylan Simpson and MA student Ryan Sandrin, the online experimental study drew on a sample of 117 participants residing in North America. The participants were randomly assigned to read one of three fictitious news articles that were either pro-PPE (highlighting health benefits), neutral or anti-PPE (lacking health benefits). Participants were then asked to rate 12 images of a uniformed male officer wearing various types of PPE alone, in combination or without any PPE.

The PPE surveyed include a surgical mask, an N95 mask, a full-face respirator mask, goggles, a face shield and single-use medical gloves. The researchers note that some of these items of PPE (such as full-face respirator masks, face shields and gloves) have been traditionally associated with negative messaging when used by police (including hostility and militarization).

"Seeing police officers routinely use what has traditionally been medical equipment is both novel and important for functionality and perception," says Simpson.

"Historically, we have seen police use full-face respirator masks and face shields during public disorder situations where tear gas and/or other chemical agents are deployed. Now, we are seeing police use this equipment in response to situations where carriers of COVID-19 may be present," he says.

The researchers found that most types of PPE did have an impact on perception. For example, wearing either a face shield, surgical mask or N95 mask enhanced perceptions of officer accountability and professionalism.

Full-face respiratory masks had more mixed results. While study participants perceived the officer wearing a full-face respirator mask as having greater accountability and professionalism, some felt it was more intimidating. For participants who read the anti-PPE article, using a full-face respirator mask also amplified perceptions of aggression and reduced perceptions of approachability and friendliness.

Study authors note that the Vancouver Police Department has supplied their officers with gloves and personally-outfitted respiratory masks and recommend their use whenever applicable. The Center for Disease Control and Prevention (CDC) has also recommended that officers use eye protection, such as face shields and goggles, to protect themselves from virus exposure.

Scientists discover key enzyme responsible for skin blistering in the elderly

2021-01-13
The Granzyme B (GzmB) enzyme, which accumulates in certain tissues as we age, has been identified as a driver of itchy and sometimes life-threatening autoimmune conditions known as pemphigoid diseases (PDs), which cause blistering and skin erosion below the skin's surface. New research led by University of British Columbia (UBC) and Vancouver Coastal Health Research Institute (VCHRI) scientists has found that a gel containing a specific and potent inhibitor of GzmB activity, VTI-1002, resulted in significant improvements on skin affected by PDs. "Blisters caused by these conditions can be extremely discomforting, unsightly and ...

USTC obtains Pd-Pt tesseracts for oxygen reduction reaction

2021-01-13
A proton exchange membrane fuel cell is a chemical cell that converts energy released when a substance reacts into electrical energy with zero emission. It is an excellent substitute for fossil fuel. However, low activity and stability of the Pt-based catalysts in the oxygen reduction reaction (ORR) of the battery cathode restricted the output power and the number of charge and discharge cycles, thus increasing the cost of the whole fuel cells. The preparation of cathode catalysts with high activity and stability is a difficult problem. In a study ...

Discovery of 'adolescent' skeletal stem cells might someday help prevent osteoporosis

Discovery of adolescent skeletal stem cells might someday help prevent osteoporosis
2021-01-13
Durham, NC - A new study reported in STEM CELLS reveals a unique population of skeletal stem cells (SSCs) that function during the transitional period between rapid bone growth and bone maintenance. This discovery provides an opportunity to determine whether alterations in the SSCs' pattern might affect bone formation, as well as helps us understand the physiological factors that regulate its timing. "This is particularly important given that anything that interferes with the proper development of bone mass during childhood and adolescence has long-lasting effects on our health, including the development of osteoporosis ...

Changes in political administration come with increased danger of international conflict

2021-01-13
BINGHAMTON, NY -- A new leader takes office and foreign rivals begin to test the waters. How tough is this new leader? Are they willing to risk war, or just full of bluster? This testing can escalate crises, increasing the risk of war as international adversaries gauge the new leader's willingness to use force. A new paper co-written by faculty at Binghamton University, State University of New York shows that when this "turnover trap" occurs depends a good deal on the politics back home, and the nature of the leader's transition into office. Binghamton University Associate Professor of Political Science Amanda Licht was among ...

CU Anschutz scientists reverse deadly impacts of asthma in mice

2021-01-13
AURORA, Colo. (Jan. 13, 2021) - Mucus in the lungs can be fatal for asthma patients, but scientists at the University of Colorado Anschutz Medical Campus have broken up those secretions at the molecular level and reversed their often deadly impacts. In a study published Monday in the journal Nature Communications, the researchers explained how they created an inhaled treatment that disrupted the production of excess mucus by reducing disulfide bonds in mice and opening up their airways. The same treatment had similar impacts on human mucus samples. "Currently about 10% of the population has asthma," said the study's lead author Christopher Evans, PhD, professor of Pulmonary Sciences & Critical ...

Bacteria carried by mosquitos may protect them against pesticides

Bacteria carried by mosquitos may protect them against pesticides
2021-01-13
A common bacterial species naturally infecting mosquitoes may actually be protecting them against specific mosquito pesticides, a study has found. Wolbachia - a bacterium that occurs naturally and spreads between insects - has become more frequently used in recent years as a means of controlling mosquito populations. Scientists at the University of Reading, and the INBIOTEC-CONICET and the National University of San Juan in Argentina, studied the effect of Wolbachia on a common mosquito species and found those carrying the bacteria were less susceptible to widely used pesticides. Dr Alejandra Perotti, an Associate Professor in invertebrate biology at the University of Reading, and a co-author of the study, said: "This shows the importance of looking more ...

Blue-light stride in perovskite-based LEDs

Blue-light stride in perovskite-based LEDs
2021-01-13
Researchers at Linköping University, Sweden, have developed efficient blue light-emitting diodes based on halide perovskites. "We are very excited about this breakthrough", says Feng Gao, professor at Linköping University. The new LEDs may open the way to cheap and energy-efficient illumination. Illumination is responsible for approximately 20% of global electricity consumption, a figure that could be reduced to 5% if all light sources consisted of light-emitting diodes (LEDs). The blue-white LEDs currently in use, however, need complicated manufacturing methods and are expensive, which makes it more difficult to achieve ...

Limits of atomic nuclei predicted

2021-01-13
Atomic nuclei are held together by the strong interaction between neutrons and protons. About ten percent of all known nuclei are stable. Starting from these stable isotopes, nuclei become increasingly unstable as neutrons are added or removed, until neutrons can no longer bind to the nucleus and "drip" out. This limit of existence, the so-called neutron "dripline", has so far been discovered experimentally only for light elements up to neon. Understanding the neutron dripline and the structure of neutron-rich nuclei also plays a key role in the research program for the future accelerator facility FAIR at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt. In a new study, "Ab Initio Limits of Nuclei," ...

A new study identifies possible biomarkers of severe malaria in African children

2021-01-13
The levels of small molecules called microRNAs (miRNAs) circulating in blood could help identify early on children with life-threatening forms of malaria, according to a study led by the Barcelona Institute for Global Health, an institution supported by "la Caixa" Foundation, in collaboration with the Manhiça Health Research Center (CISM) in Mozambique. The results, published in Emerging Infectious Diseases journal, could also help better understand the mechanisms underlying severe malaria. Malaria mortality among young African children remains unacceptably high. To improve the outcome, it is important to rapidly identify and treat children with severe forms of the disease. ...
