Highly emotional people drawn to cats for stress relief programs

Study finds high level of interest in adding cats to university-based animal assisted interventions

Peer-Reviewed Publication

WASHINGTON STATE UNIVERSITY

Cats are often left out of university-based animal assisted interventions aimed at reducing stress, but new research shows many people, especially those with strong and highly reactive emotions, want and would benefit from feline interactions.

Universities implementing animal-assisted interventions like “Pet Your Stress Away” events has proven benefits, but more than 85% of them only include dogs, according to researchers. A new paper published in the journal Anthrozoös found a high level of interest in adding cats to the mix.

The study found that several factors shaped a positive response to a cat visitation program and revealed that the personality trait of emotionality played an important role. Emotionality, part of a well-established psychology model called the Big Five personality traits, indicates a person has strong emotions and is highly reactive to them.

“Emotionality is a pretty stable trait; it doesn’t fluctuate and is a quite consistent feature of our personalities,” said co-author Patricia Pendry, a professor in Washington State University’s Department of Human Development. “We found that people on the higher end of that scale were significantly more interested in interacting with cats on campus. Given that prior research has shown that such individuals may be more open to forming strong attachments to animals, it makes sense they would want cats to be included in these programs.”

Pendry and lead author Joni Delanoeije, from Belgian university KU Leuven, explored the level of interest in adding cats to the interventions, plus how human characteristics may influence that interest. The scientists also examined whether university employees, who are commonly excluded from such programs, would be interested in participating.

“Anecdotally, we’ve always been told that cat people are different from dog people, and that most students are not interested in interacting with cats,”Pendry said. “Our results revealed that students are interested in interacting with cats and that this interest may be driven by personality traits.”

The researchers surveyed more than 1,400 university students and staff for the paper from over 20 universities.

The link between personality and openness to interacting with cats mattered even after accounting for openness to a dog visitation program, being a cat owner and identifying as female. The researchers also accounted for negative influences such as having a cat allergy or cat phobia, which logically reduced participants’ interest in interacting with felines.

One reason university interventions tend to be dog-focused is the larger number of canine therapy animals available and a common view that cats may be unsuitable for therapy roles, Pendry said.

“There’s a perception that dogs exist to please people,” said Pendry, who classifies herself as a dog and a cat person. “While I may describe cats as ‘discerning,’ they are often perceived as unpredictable, aloof, or finicky—traits that can be difficult for some to be around.”

In previous studies where results weren’t divided into different animal species, Pendry said it was easy to tell cat people from dog people.

“Some people came in and made an immediate beeline for cats and others for dogs,” she said. “I was pleasantly surprised by how many people were interested in interacting with cats, which made me interested in learning more about why they made those choices.”

Researchers included faculty and staff, in addition to students, and found no differences between the groups.

“We think of college student populations as being unique, and in several ways they are,” Delanoeije said. “But when we looked at university employees, the results were very similar: Personality mattered more than being a student or employee. That shows there would be interest in having animal interventions in non-university settings and other workplaces.”

Having the option of being able to choose an interaction with a cat or dog, or both, may increase the number of people interested in attending an animal-assisted intervention, which is shown to lower stress and make people feel better. That’s the whole point for the scientists.

“Our study shows that we may be able to reach a larger audience by offering interventions that include dogs and cats. People who are on the higher end of the emotionality trait may be more likely to participate and benefit from these interactions,” Pendry said. “We’re looking for ways to help more people reduce their stress levels. Adding cats may be another way to reach a broader audience.”

We need to stop thinking of insects as ‘creepy crawlies’ and recognise their keystone role in ecosystems, say scientists

We need to stop thinking of insects as creepy crawlies and focus on the huge benefits they bring to people and the natural environment, scientists say.

The widespread and deeply engrained cultural perception of insects as creepy crawlies is a key factor holding back the public’s appreciation of the role they play within ecosystems. This perception is in part reflected in government biodiversity policy inaction across the globe, they argue.

This point is among a range of actions highlighted as part of a new paper published in Ecology and Evolution produced by an international team of entomologists which outlines a ‘battle plan’ including steps needed to prevent further insect losses across the globe.

Led by Dr Philip Donkersley of Lancaster University and co-authored by scientists from the University of Hong Kong, the Czech Academy of Sciences and Harper Adams University, the paper is a call to action targeted at other entomologists to step up advocacy for insects.

Despite 30 years of intergovernmental reports highlighting biodiversity targets, global insect abundance, biomass and diversity continues to decline. The paper considers the lack of progress in protecting insects and why meaningful change has not happened.

“Biodiversity, including insect, declines are often unintended consequences of human activities with human wellbeing nearly always trumping nature conservation, and this is likely to continue until we reach a point where we see flat-lining ecosystems are detrimental to our own species,” said Dr Donkersley. “Intergovernmental action has been slow to respond, kicking in only when change becomes impossible to ignore. If we are to see political attitudes and actions change then first societies’ perception of insects needs to be addressed.”

The paper highlights the range of benefits that insects bring, including some that are lesser known. These benefits include fundamental roles within ecosystems through interactions with plants including as pollinators, as a food for other animals, and as a food source for people in many parts of the world. Other benefits the authors highlight include insects’ contributions to wellbeing, culture and innovation, such as the benefits people derive from seeing butterflies in parks and gardens, their inclusion in poetry and literature, and their inspiration for a range of technologies, cosmetics and pharmaceuticals.

The researchers have outlined strategic priorities in their action plan to help support the conservation of insects. These include:

  • to proactively and publicly address government inaction
  • highlighting the technological developments we owe to the insects, and that there is a lot still to be discovered
  • aligning with bird, plant and mammal conservation groups to show species interdependencies and knock-on benefits insect conservation has for other animals
  • Engage public and school students with the wonders of the insect world to counter perceptions of insects as threatening ‘creepy crawlies’

 

“The benefits we gain from the insect world are broad, yet aversion of phobias of invertebrates are common and stand firmly in the path of their conservation,” said Dr Donkersley. “We need to move beyond this mindset and appreciate the huge role they play in ecosystems, foodchains, mental health, and even technological innovation.

“This perception change is a crucial step, alongside other measures we outline in this paper. Immediate and substantial actions are needed to protect insect species in order to maintain global ecosystem stability.”

The steps are outlined in the paper ‘Global insect decline is the result of wilful political failure: A battle plan for entomology’.

Authors on the paper are Dr Philip Donkersley, Lancaster University, Dr Louise Ashton, University of Hong Kong, Dr Greg Lamarre, Czech Academy of Sciences, and Dr Simon Segar, Harper Adams University.

Biodiversity information conference brought 400 scientists from 41 countries to Bulgaria to fast-forward what we know about life on Earth

Between 17th and 21st October, about 400 scientists took part in a hybrid meeting dedicated to the development, use and maintenance of biodiversity data, technologies, and standards used across the world.

For the 37th time, the global scientific and educational association Biodiversity Information Standards (TDWG) brought together experts from all over the globe to share and discuss the latest developments surrounding biodiversity data and how they are being gathered, used, shared and integrated across time, space and disciplines.

This year, the conference was hosted by Pensoft - an international scholarly publisher and technology provider based in Sofia - in collaboration with the National Museum of Natural History (Bulgaria) and the Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Science.

This was the first time the event happened in a hybrid format. It was attended by 160 people on-site, while another 235 people joined online. The conference abstracts, submitted by the event’s speakers ahead of the meeting, provide a sneak peek into their presentations and are all publicly available in the TDWG journal Biodiversity Information Science and Standards (BISS).

Amongst the conference participants, there were scientists in the fields of natural sciences, as well as many data scientists, informaticians, computer scientists, and software engineers. Many attendees have affiliations with key natural history museums and institutions across the globe. 

Put simply, the main task and dedication of the TDWG association is to develop and maintain standards and data-sharing protocols that support the infrastructures (e.g., The Global Biodiversity Information Facility - GBIF), which aggregate and facilitate use of these data, in order to inform and expand humanity’s knowledge about life on Earth.

Biodiversity data may include classification of organisms, their biology, genetics and distribution, as well as the whole chronology of their existence, traced back through time with information about who collected the specimens and observation data, the names of scientists involved, and their related scholarly work and publications.

The standards developed and maintained by TDWG provide a foundation to enable the creation, maintenance and development of a wide range of digital platforms, tools and workflows in the biodiversity data domain. All these technologies allow biodiversity scientists to build on the knowledge of their predecessors and make data freely accessible for use in policy decisions and further avenues of scientific inquiry.

Let’s imagine that there is a scientist who is interested in studying the distribution of a threatened animal species. While on a field trip, she spots what looks or acts like her target species, but the colouration of these particular animals is different. The question arises whether she has just found a little known variation of the species or could it be that it is a new, yet undescribed species? If the latter is true, it could change the whole picture we have so far painted for the ecosystem in question.

To answer the question, the scientist will need to be aware of what has already been published about the species of interest, and explore the related data spread across dozens of specialised platforms and databases. She will also need to take various distinct characters, e.g. morphology, physiology, DNA and behavioural traits, analyse them and compare them with those of related species. Not until the results are out, will the researcher be able to confirm whether this recently identified population indeed belongs to the species of initial interest, or whether it is totally new to science.

But why is it so important that we know if there is one or multiple species of seemingly the same animal in a given habitat? Suffice it to say, each and every species: be it an animal, a plant or a fungus, plays a key role in the ecosystem, while all living creatures—including humans—depend for their very survival on the well-being of their ecosystem. Given their strong interconnectedness and interdependability, we need to understand and closely monitor their presence, distribution and interactions with each element of the environment.

So, here is where the role of biodiversity data comes into play: biodiversity data underlie everything we know about the natural world around us. Even we, as individuals, are heavily dependent on what we know (or don’t know) about the other organisms in our ecosystem.

It is the goal of everyone volunteering their time and expertise to TDWG to enable the scientists interested in the world’s biodiversity to do their work efficiently and in a manner that can be understood, shared and reused by others.

If there are optimised and universal standards in the way researchers store and disseminate biodiversity data, all those biodiversity scientists will be able to find, access and use the knowledge in their own work much more easily. As a result, they will be much better positioned to contribute new knowledge that will later be used in nature and ecosystem conservation by key decision-makers.

“We are proud to have been selected to be the hosts of this year’s TDWG annual conference and are definitely happy to have joined and observed so many active experts network and share their know-how and future plans with each other, so that they can collaborate and make further progress in the way scientists and informaticians work with biodiversity information,” said Pensoft’s founder and CEO Prof. Lyubomir Penev. 

“As a publisher of multiple globally renowned scientific journals and books in the field of biodiversity and ecology, at Pensoft we assume it to be our responsibility to be amongst the first to implement those standards and good practices, and serve as an example in the scholarly publishing world. Let me remind you that it is the scientific publications that present the most reliable knowledge the world and science has, due to the scrutiny and rigour in the review process they undergo before seeing the light of day,” he added.

“It’s wonderful to be in the Balkans and Bulgaria for our Biodiversity Information and Standards (TDWG) 2022 conference! Everyone’s been so welcoming and thoughtfully engaged in conversations about biodiversity information and how we can all collaborate, contribute and benefit,” said Deborah Paul, Chair of TDWG, a biodiversity informatics specialist and community liaison at the University of IllinoisPrairie Research Institute's Illinois Natural History Survey and also an active participant in the Society for the Preservation of Natural History Collections (SPNHC), the Entomological Collections Network (ECN), ICEDIG, the Research Data Alliance (RDA), and The Carpentries.

“Our TDWG mission is to create, maintain and promote the use of open, community-driven standards to enable sharing and use of biodiversity data for all,” she added.

Following the week-long conference in Sofia, a good many of the participants set off straight for another Bulgarian city and another event hosted by Pensoft. Between 22nd and 24th October, the General Assembly of the Horizon 2020-funded project BiCIKL (abbreviation for Biodiversity Community Integrated Knowledge Library) took place in Plovdiv. The project involves many of the active participants in the TDWG community, including Pensoft, who is the project coordinator.

BiCIKL’s goal is to create a centralised place to connect all key biodiversity data by interlinking 15 research infrastructures and their databases. The 3-year European Commission-supported initiative kicked off in 2021 and involves 14 key natural history institutions from 10 European countries.

Study reveals soil moisture plays the biggest role in underground spread of natural gas leaking from pipelines

Peer-Reviewed Publication

SOUTHERN METHODIST UNIVERSITY

DALLAS (SMU) – Soil moisture content is the main factor that controls how far and at what concentration natural gas spreads from a leaked pipeline underground, a new study has found.

Pipeline operators need to factor how the amount of water found in surrounding soil affects gas movement when trying to determine the potential hazards posed by a pipeline leak, said SMU’s Kathleen M. Smits, who led the study recently published in the journal Elementa that examined soil properties from 77 locations around the country where a gas leakage had occurred. 

“We don’t need to look any further than Dallas or Georgetown, Texas to see where underground pipeline leaks have the potential to result in catastrophic outcomes,” said Smits, SMU Lyle School of Engineering Chair of Civil and Environmental Engineering and Solomon Professor for Global Development. “We often see that such incidents are the result of a lack of clear protocols to detect the leaks or assess damage. That’s why there should be more focus on the importance of environmental factors such as soil moisture and how to properly account for them in leak scenarios.” 

In general the team, co-led by Younki Cho, a research scientist at Colorado State University’s Energy Institute, found that methane gas leaking from a pipeline does not spread as far when the soil moisture content increases. That results in a higher concentration of methane gas close to the leak site in more moist soil, the study revealed.

The opposite was true with drier soil.

But Smits stressed that simply knowing how wet the ground is at the time of the leak is not enough to make conclusions about how soil moisture content impacts gas movement. The moistness of the soil – or lack thereof – at the time of leak triggers different complex behaviors in the soil when methane gas seeps into the same spaces as water and oxygen in the pores of the soil. Soil moisture content can also change over time because of weather and other factors such as seasonal water table levels. 

“You have to understand how the moisture controls both the movement and concentration together,” Smits said. “This is something we can assist [pipeline owners] with going forward in addressing leak incidents.”    

The research team looked at more than 300 soil samples from leak sites around the country. The samples – which were taken at the time of the leak and again after the leak was repaired – were weighed when they were wet. They were also weighed a second time after they had been dried out in an oven. 

“The difference in the dry and wet weights, linked with knowledge of the volume of the soil sample, allowed us to calculate the soil moisture,” Smits explained. 

Other soil qualities like its texture and permeability were also examined by the team, but did not demonstrate as much impact on how natural gas moved belowground.   

Other co-authors were Nathaniel L. Steadman, from the Department of Civil Engineering at the University of Texas at Arlington; Bridget A. Ulrich, from the Natural Resources Research Institute at the University of Minnesota Duluth; Clay S. Bell, from the CSU Energy Institute; and Daniel J. Zimmerle, Director and Principal Director of the Methane Emissions Technology Evaluation Center at CSU.   

Walking surveys better at finding pipeline leaks than mobile detection under certain circumstances

In another study aimed at improving gas leak detection, Smits and researchers from CSU’s Energy Institute found that there are instances where operating a mobile detection unit from the front or roof of a car were not as effective as walkers carrying a handheld detection instrument.  

In a mobile survey, the detection unit measures for elevated levels of methane gas in the air as the car is driving. A higher traveling speed or wind speed outside the car resulted in a lowered probability of leak detection when compared to a foot patrol. 

“For example, if you just isolated the speed of travel – comparing a person walking at 2 to 3 miles per hour versus a car driving at a slow speed of 20 to 30 mph – the probability of detecting a leak drops from 85 percent for a walking survey to 25 percent for a car,” Smits said. 

The study, published in the journal Environmental Pollution, showed that atmospheric stability also had an effect on mobile surveys.

Atmospheric stability essentially determines whether air will rise, sink, or do nothing. Warm, less dense air rises (unstable), while cooler, more dense air sinks (stable). Air staying at the same altitude is considered neutral. 

Researchers found that mobile surveys conducted at speeds between 2 to 11 miles per hour got progressively less effective (from 85 percent to 60 percent) at finding a leak as the atmospheric stability went from extremely unstable conditions to extremely stable. Walking surveys conducted under these same conditions did not reflect variability. 

“Walking surveys find the most leaks, by far, but they are labor intensive and cost a lot of money,” Smits noted. “This study shows that if operators want to use another method such as a mobile survey, they need to thoughtfully choose a suitable survey speed under different weather conditions to achieve a detection probability equivalent to the traditional walking survey.”  

The findings could apply to any type of buried pipeline, Smits said.

Cho, Bell, Cho and Zimmerle from CSU assisted with this study, as did Stuart N. Riddick, a research scientist from the Energy Institute. Shanru Tian, a Ph.D. student in the Department of Civil Engineering at the University of Texas at Arlington, was the lead author of this study.

SAN ANTONIO — Oct. 25, 2022 — Southwest Research Institute (SwRI) has created the next generation of transducers that use ultrasonic guided wave technology to detect anomalies in pipes, enabling users to prevent leaks before they start. The device, which utilizes the SwRI-developed Magnetostrictive Sensor® (MsS®) technology, will be showcased at the American Society for Nondestructive Testing’s (ASNT) Annual Conference in Nashville, Tennessee, from October 31 to November 3.

“Pipeline corrosion resulting in leaks is very common,” said SwRI Staff Engineer Sergey Vinogradov, who developed the technology with Staff Engineer Keith Bartels and other SwRI staff members. “There are only a few current methods to detect defects before they cause leaks. Quite often, the pipe is repaired and re-inspected after a leak occurs. We’ve developed a technology that can consistently monitor the pipe’s condition, hopefully preventing leaks from happening in the first place.”

The technology is known as a Magnetostrictive Transducer (MsT) Collar. It was originally developed by SwRI in 2002. The updated version has a flat, thin design allowing it to be used on pipes in tight spaces. In custom configurations, it can withstand heat up to 400 degrees Fahrenheit. The new, segmented MsT design also features eight sensors that give the transducer the ability to more accurately identify where in the pipe corrosion is occurring.

The MsT Collar utilizes magnetostrictive sensors, which generate and receive guided waves that propagate along an elongated structure, guided by its boundaries. This technique allows the waves to travel long distances with little loss in energy. In some cases, hundreds of meters can be inspected from a single location, though obstacles such as couplings would require an additional sensor.

“Instead of using one sensor to cover an entire pipe circumference, allowing only the axial location of an anomaly to be measured, we now have eight sensors in the transducer,” Vinogradov said. “Each of the sensors are independently connected to the electronics so that all possible guided wave signals can be acquired. Algorithms combine this information to better detect and locate the anomaly both axially and circumferentially, and the growth of the corrosion can be monitored by examining data sets acquired over time.”

The MsS system can send data to a remote terminal via a wireless transmitter unit or by means of a wired connection. It is designed primarily for oil and gas transmission pipelines to prevent costly and damaging leaks before they begin. However, the technology is versatile and has been used for other industrial pipes such as those used for water, heating, or in chemical plants.

Vinogradov and Bartels will demonstrate the MsT Collar at the ASNT Annual Conference in Nashville, Tennessee, from October 31 to November 3 at booth 1219.

SwRI’s Nondestructive Evaluation and Sensor Systems Section develops tools and techniques for nondestructive inspection, evaluation and testing featuring guided waves, computed tomography, ultrasonics, electromagnetics and other techniques.
