High-tech start-ups benefit from Twitter hype
Study shows correlation between Twitter sentiment and the valuation of start-ups by venture capitalists / Patents are stronger indicators of long-term success
2021-02-16
(Press-News.org) The short message service Twitter has played a prominent role in US politics in recent weeks and months and attracted a lot of attention. Even in business, Twitter users' tweets are being closely followed and used as a basis for decision-making. A new study shows that venture capitalists can also be influenced by Twitter sentiment when valuing start-up companies from the high-tech sector. "However, the sentiment signals on Twitter say nothing about the long-term investment success of such a start-up. Patent applications, for example, are much better suited for this," said Professor Andranik Tumasjan from Johannes Gutenberg University Mainz (JGU) in Germany. He conducted the study together with Professor Reiner Braun and Dr. Barbara Stolz from the Technical University of Munich. The results were published in the renowned Journal of Business Venturing.
Twitter as a globally established information platform in the business and technology sector
The researchers' main question was whether and how strongly venture capitalists may be influenced by media hypes. "Out of all social media platforms, Twitter is the most suitable medium for such a study in the business and technology sector," emphasized Tumasjan. Founded in 2006, the microblogging service is now the world's most important social media platform for the short-term exchange of information on new technologies and trends, such as artificial intelligence and business activities in general. Twitter sentiment could therefore also influence venture capitalists' start-up valuations. "Young start-up companies are particularly difficult to value when they have just been launched, as nothing has yet been produced or sold. This means that there is a huge amount of uncertainty involved when venture capitalists decide whether to invest in tech start-ups," explained Tumasjan.
But can Twitter sentiment actually predict the valuations and long-term success of high-tech start-ups? The research team analyzed over 400,000 English-language tweets about 37 different technologies and more than 4,600 venture capital financing rounds between 2008 and 2017. The tweets were analyzed using VADER, a dictionary specifically designed to measure social media sentiment. "This gives us an objective indicator of Twitter sentiment and how people are talking about a particular technology," said Tumasjan. The study included a total of 4,005 US companies that were on average about five years old. The venture capitalists' start-up valuations were assessed using the so-called pre-money valuation. The long-term success of an investment in a start-up was measured by an initial public offering (IPO) or acquisition of a start-up.
Twitter sentiment is a "weak signal," whereas patents are a "strong signal"
The results show that Twitter sentiment about technology do, in fact, significantly predict the venture capital valuations of young high-tech companies whose business model is based on these technologies. However, Twitter cannot predict long-term investment success as indicated by a start-up's IPO or acquisition. "Twitter sentiment is a comparatively novel signal in venture capital financing, and it is at the same time only a weak signal in comparison to patents," resumed Tumasjan. Patents and patent applications have been shown to be strong signals for years, as they are associated with both the valuation and the long-term investment success.
In summary, from the perspective of start-up founders Twitter hype of a technology or trend may be beneficial to obtain a higher capital valuations. However, Professor Andranik Tumasjan recommends that venture capitalists should not let themselves be distracted by Twitter sentiment and should instead focus on other signals, such as patents. This also applies to experienced venture capitalists: according to the study, they are not immune to Twitter hype either.
Andranik Tumasjan studied at Ludwig-Maximilians-Universität München and received both his doctorate and postdoctoral degree in management from the Technical University of Munich. He has been a professor and head of the Management and Digital Transformation (MDT) research group at Johannes Gutenberg University Mainz since 2017. His research focuses on how digital technologies and trends influence management and the emergence of new organizational, leadership, and business models as well as entrepreneurial opportunities. One current focus of his research is the potential of blockchain technology. In previous studies, he investigated to what extent Twitter sentiment can predict events such as political elections and stock market movements.

Since the 1980s, the physical and mental health of Swedish children and young people has been measured by way of surveys. One of these is the international "Health Behavior in School-aged Children Survey" (HBSC), which is taken by 11-, 13- and 15-year-olds every fourth year during a class in school.
Researchers Anette Wickström and Kristin Zeiler at Linköping University wanted to study the survey to see which norms can be conveyed in health surveys, something that has rarely been studied. The results have been published in the journal Children & Society.
"The study shows that survey questions on parents' occupation and financial situation create norms about how you should ...

A subtype of asthma in adults may cause higher susceptibility to influenza and could result in dangerous flu mutations.
University of Queensland-led animal studies have found that paucigranulocytic asthma (PGA) - a non-allergic form of the condition - allows the flu virus to flourish in greater numbers in sufferers.
UQ PhD candidate Ms Katina Hulme said this was due to the asthma's suppression of the immune system.
"We were first tipped off about this during the 2009 swine flu pandemic," Ms Hulme said.
"Asthma was identified as the most common underlying medical condition in ...

These observations might be useful for the future development of new antibacterial strategies. The team reports in the journal Applied and Environmental Microbiology on 12 February 2021.
Bacterial groups in search of food
We commonly know predator-prey relationships from the animal kingdom, but they are also a survival strategy of certain bacteria: bacterial predators actively kill bacteria of other species in order to feed on them. The predatory species include many myxobacteria, which are widespread in the soil and display unique behavioural patterns: many cells assemble into large groups and go in search of food together or, in the event of nutrient ...

Scientists from the University of Gothenburg, Sweden presents evidence that hospital wastewater, containing elevated levels of antibiotics, rapidly kills antibiotic-sensitive bacteria, while multi-resistant bacteria continue to grow. Hospital sewers may therefore provide conditions that promote the evolution of new forms of antibiotic resistance.
It is hardly news that hospital wastewater contains antibiotics from patients. It has been assumed that hospital sewers could be a place where multi-resistant bacteria develop and thrive due to continuous low-level antibiotic exposure. However, direct evidence for selection of resistant bacteria from this type of wastewater has been lacking, until now.

A polymer that is custom designed to produce light that penetrates murky environments has shown promise in bioimaging trials, where it can detect nano-sized particles underneath the surface of realistic tissue models.
Recent studies have demonstrated that fluorescent probes -- light-emitting materials that attach to tiny targets such as cells -- are particularly useful for bioimaging when they radiate in the shortwave infrared (SWIR) region of the optical spectrum. Because this type of fluorescent light penetrates deeper into biological objects without being absorbed or scattered, SWIR ...

Humans inhabit an incredible range of environments across the globe, from arid deserts to frozen tundra, tropical rainforests, and some of the highest peaks on Earth. Indigenous populations that have lived in these extreme environments for thousands of years have adapted to confront the unique challenges that they present. Approximately 2% of people worldwide live permanently at high altitudes of over 2,500 meters (1.5 miles), where oxygen is sparse, UV radiation is high, and temperatures are low. Native Andeans, Tibetans, Mongolians, and Ethiopians exhibit adaptations that improve their ability to survive such conditions. Andeans, for example, display increased chest circumference, elevated oxygen saturation, and a low hypoxic ventilatory response, enabling them to thrive at exceptionally ...

Scientists created a framework to test the predictions of biological optimality theories, including evolution.
Evolution adapts and optimizes organisms to their ecological niche. This could be used to predict how an organism evolves, but how can such predictions be rigorously tested? The Biophysics and Computational Neuroscience group led by professor Gašper Tkačik at the Institute of Science and Technology (IST) Austria has now created a mathematical framework to do exactly that.
Evolutionary adaptation often finds clever solutions to challenges posed by different environments, from how to survive in the dark depths of the oceans to creating intricate organs such as an eye or an ear. But can we mathematically predict these outcomes?
This is ...

Fossilised remains of a fish that grew as big as a great white shark and the largest of its type ever found have been discovered by accident.
The new discovery by scientists from the University of Portsmouth is a species of the so-called 'living fossil' coelacanths which still swim in the seas, surviving the extinction that killed off the dinosaurs.
The discovery was purely serendipitous. Professor David Martill, a palaeontologist from the University's School of the Environment, Geography and Geosciences, had been asked to identify a large ...

In plants, the "meristem" refers to a type of tissue comprising undifferentiated cells from which various other plant organs can develop through cell division and differentiation. These "plant stem cells" give rise to shoots, leaves and roots, but also spikes and flowers.
The research team including members of the Cluster of Excellence on Plant Sciences CEPLAS investigated the function of a gene responsible for the different spike forms of wheat and barley. This gene controls the activity of the spike and floret meristems and thus the number of spikelet ...
