"Terekhov and his colleagues showed that the notion of space as environment-independent cannot be deduced only by exteroceptive information, as this information varies greatly depending on what is found in the environment."
"We show that the notion of space as environmentindependent cannot be deduced solely from exteroceptive information, which is highly variable and is mainly determined by the contents of the environment."
"If we want robots to be truly intelligent, we should not build them using abstract notions, but instead, provide them with algorithms that will allow them to develop such notions themselves." Terekhov and his colleagues showed that the notion of space as environment-independent cannot be deduced only by exteroceptive information, as this information varies greatly depending on what is found in the environment. This notion could be better defined by looking into functions that link motor commands to changes in stimuli that are external to the agent."
"One of the most fundamental perceptual notions, space, cannot be an exception to this requirement. We show that the notion of space as environmentindependent cannot be deduced solely from exteroceptive information, which is highly variable and is mainly determined by the contents of the environment. The environment-independent definition of space can be approached by looking into the functions that link the motor commands to changes in exteroceptive inputs."

"Hyperspectral and RGB imaging not only address this issue, Ge said, but should also further speed the process of simultaneously comparing multiple traits among plant varieties."
"Hyperspectral imaging can be a very powerful tool to phenotype biochemical traits of the whole maize plants, complementing RGB for plant morphological trait analysis."
"In killing the plant, these methods kept the researchers from observing how it would have grown and developed afterward. Hyperspectral and RGB imaging not only address this issue, Ge said, but should also further speed the process of simultaneously comparing multiple traits among plant varieties. "How to capture all of these dynamic traits is really a challenging task without these high-throughput systems," Ge said."
"LWC is successfully predicted with the hyperspectral images for both genotypes (R 2 = 0.81 and 0.92). Hyperspectral imaging can be a very powerful tool to phenotype biochemical traits of the whole maize plants, complementing RGB for plant morphological trait analysis. However, the current rate of increase in yield will not keep pace with this increased demand for food and fuel over the next 35 years ."

"But unlike rudeness among friends, discourteous behavior in the workplace can have real implications for careers, hiring and even workplace efficiency, with tension among coworkers harming productivity. A timely new study co-authored by Peter W. Cardon of the USC Marshall School of Business and colleagues at Howard University is the first to provide an empirical baseline for how attitudes towards mobile phone use actually break down across gender, age and region. Published today in the journal Business Communication Quarterly, the research offers a critical baseline for how attitudes toward technology may change over time and serves as a guide to navigating social expectations around polite smartphone use."
"This seems to indicate major generational differences. One of the more interesting findings was the major gender gap in perceived appropriateness of mobile phone actions. As far as checking text messages, sending text messages, and answering calls, men are nearly twice as accepting of these behaviors."

"Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags."
"In hindsight, however, this may not have been the right decision given the performance deterioration observed after they began charging for the two checked bags."
"Southwest's improved departure time performance was not as significant as its rival airlines, which did charge for checked bags, and it appears to have hurt one of Southwest's historical competitive advantages in customer service. Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags. The study estimates Southwest loses approximately $24 million for not charging for the first checked bag and $35 million for not charging for the second one per year."
"We have an indication that this occurred at some level as our results support the argument that after initially observing little performance decline, the airlines felt the need to shorten their scheduled block times. In hindsight, however, this may not have been the right decision given the performance deterioration observed after they began charging for the two checked bags. Increased boarding times as a result of baggage fees have financial implications as well."

The findings, published in the journal Management Science, shows airlines improved their median departure time between 3.3 to 4.2 minutes and reduced average departure delays between 1.3 to 2 minutes, depending on whether they charged for the first or second checked bag. The reductions are significant because departure times and mitigating delays are crucial to so many other facets of the business, such as the number of flights airlines can offer and their image among potential customers."

"While the total energy delivered by adaptive stimulation was substantially less than that of open-loop stimulation, blinded clinical ratings confirmed similar efficacy for both approaches."
"Stimulation was reduced when it identified dyskinesia-related brain activity and increased when brain sensing indicated no dyskinesia to minimize deep brain stimulation-related side effects. Doctors saw and patients noticed no differences in the improvement in movement under adaptive stimulation versus constant, open loop stimulation set manually by the researchers. Because adaptive deep brain stimulation did not continuously stimulate the brain, the system saved about 40 percent of the device's battery energy used during traditional stimulation."
"We have demonstrated the feasibility of adaptive DBS in PD using a fully implantable device, with feedback control provided by a cortical gamma band oscillation related to the emergence of dyskinesia, a common adverse effect of levodopa therapy and of STN DBS. While the total energy delivered by adaptive stimulation was substantially less than that of open-loop stimulation, blinded clinical ratings confirmed similar efficacy for both approaches. The classifier algorithm performed as expected, appropriately detecting changes in gamma band power and triggering reduction in DBS amplitude when the gamma threshold was exceeded."

The same policy may have determined a change in other passengers' behavior in the sense that fewer passengers may have checked a second bag while still flying their preferred airline. Another possible explanation is that price-sensitive customers of those airlines that charged for one checked bag started flying Southwest instead."

"Or, as the researchers write in the new paper, "For the time being, there seems to be no easy way to design algorithms that would reconcile moral values and personal self-interest."

For instance, 76 percent of respondents believe it is more moral for an autonomous vehicle, should such a circumstance arise, to sacrifice one passenger rather than 10 pedestrians."
"For example, our scenarios did not feature any uncertainty about decision outcomes, but a collective discussion about moral algorithms will have to tackle the concepts of expected risk, expected value, and blame assignment. Such liability considerations will need to accompany existing discussions of regulation [21] , and we hope that psychological studies inspired by our own will be able to inform this discussion.

"It discredits several cryptographic systems that until now were assumed to provide sufficient security safeguards. Although this work is still theoretical, it is likely to have repercussions especially on the cryptographic applications of smart cards, RFID chips, etc. The algorithm they devised stands out from the best algorithms known to date for this problem."
"-The complexity result relies on three key heuristics: the existence of a polynomial representation of the appropriate form; the fact that the smoothness probabilities of some non-uniformly distributed polynomials are similar to the probabilities for uniformly random polynomials of the same degree; and the linear independence of some finite field elements related to the action of PGL 2 (F q ). Although we insist on the case of finite fields of small characteristic, where quasi-polynomial complexity is obtained, our new algorithm improves the complexity of discrete logarithm computations in a much larger range of finite fields. More precisely, in finite fields of the form F q k , where q grows as L q k (α), the complexity becomes L q k (α + o(1))."

Southwest's improved departure time performance was not as significant as its rival airlines, which did charge for checked bags, and it appears to have hurt one of Southwest's historical competitive advantages in customer service. Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags."
"We have an indication that this occurred at some level as our results support the argument that after initially observing little performance decline, the airlines felt the need to shorten their scheduled block times. In hindsight, however, this may not have been the right decision given the performance deterioration observed after they began charging for the two checked bags.

"Southwest's improved departure time performance was not as significant as its rival airlines, which did charge for checked bags, and it appears to have hurt one of Southwest's historical competitive advantages in customer service."
"Since Southwest Airlines is the only major U.S. airline that does not charge for two checked bags, it resembles a control variable of operational performance in a quasi-experiment 3 when compared against competing airlines (that did begin charging for checked bags) that operated in the same airports."
"So, a drop in total baggage volume benefits not only the airlines that charge baggage fees but also those that do not. Southwest's improved departure time performance was not as significant as its rival airlines, which did charge for checked bags, and it appears to have hurt one of Southwest's historical competitive advantages in customer service. Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags."
"Thus, the implementation of checked bag fees (a marketing decision) provides an ideal setting to study how an industry changed, or coordinated, their operations to respond to this marketing strategy change. Since Southwest Airlines is the only major U.S. airline that does not charge for two checked bags, it resembles a control variable of operational performance in a quasi-experiment 3 when compared against competing airlines (that did begin charging for checked bags) that operated in the same airports. As Southwest Airlines might have gotten new customers who used to fly the now-baggage fee charging airlines, we do not have a true experiment, and consequently we do not employ a traditional difference-in-difference approach in our analysis."

"Southwest's improved departure time performance was not as significant as its rival airlines, which did charge for checked bags, and it appears to have hurt one of Southwest's historical competitive advantages in customer service. Southwest's "bags fly free" policy is likely not free based on lost opportunity cost, mostly because it could be offering more flights per day with increased boarding times due to charging for checked bags. The study estimates Southwest loses approximately $24 million for not charging for the first checked bag and $35 million for not charging for the second one per year."
"We expect that the price-insensitive passengers or those passengers traveling with only one checked bag were indifferent to this policy change. The same policy may have determined a change in other passengers' behavior in the sense that fewer passengers may have checked a second bag while still flying their preferred airline. Another possible explanation is that price-sensitive customers of those airlines that charged for one checked bag started flying Southwest instead."

"These findings indicate that the baggage fees did influence customer behavior, but in the case of charging for both checked bags, not in the direction the airlines had hoped for."
"The most positive changes in on-time departures occurred at major hub airports because less checked bags had to be moved through massive systems once passengers change planes. The number of baggage-related complaints per 1,000 passengers dropped as airlines' departure delay performance improved once most charged for checked bags. The findings likely open the door for future research on how the unbundling of airline services influences the performance of their operations, Arikan says."
"When the airlines began charging for two checked bags, we find no significant change in departure performance of legacy carriers, but a degradation of departure performance of low-cost carriers. These findings indicate that the baggage fees did influence customer behavior, but in the case of charging for both checked bags, not in the direction the airlines had hoped for. The degradation of departure performance appears to be especially bad for the low-cost carriers, as it appears that their more price sensitive passengers may have begun carrying on more baggage to avoid the checked bag fees."

"The below-the-cabin effect dominates the above-the-cabin effect." The findings, published in the journal Management Science, shows airlines improved their median departure time between 3.3 to 4.2 minutes and reduced average departure delays between 1.3 to 2 minutes, depending on whether they charged for the first or second checked bag. The reductions are significant because departure times and mitigating delays are crucial to so many other facets of the business, such as the number of flights airlines can offer and their image among potential customers."
"Hence, a Tobit regression model is appropriate here. The estimation model of the impact of the checked bag fees on the spillover-adjusted departure delay is shown in (1)."

"The hippocampus in humans is therefore necessary for facilitating navigation even when the navigator is an expert of very longstanding."
"She didn't find this same difference in her new study because, she speculates, front-end shrinkage may happen after the four years of training. The hippocampus's rear section seems to be important for spatial navigation specifically, but Maguire says the front end's role remains more mysterious. Maguire says she was "greatly relieved" by the results of her study, which appears in the December issue of Current Biology."
"However, in his navigation, TT was very reliant on main artery or 'A' roads, and became lost when navigation depended instead on non-A roads (figure 4). The hippocampus in humans is therefore necessary for facilitating navigation even when the navigator is an expert of very longstanding. Thus expertise, while taking many years to Review."

Surprisingly, the researchers found that not only does the second law hold at such small scales, but there are actually many other second laws at work."
"Operations which pump energy into or from the system can be incorporated into the paradigm by including the source of energy as an ancillary system. This paradigm is equivalent to ones in which we allow interaction Hamiltonians rather than unitaries, or where we allow for a Hamiltonian which changes with time, provided that all ancillas are carefully accounted for [ . Considering such resources are crucial, since the experimenter who is trying to extract work or otherwise manipulate a system, should be allowed as much ingenuity as possible."

"Another possibility is that bilateral adaptive stimulation may be necessary for clinical benefit and that this is why we did not see a clinical improvement (since we tested only unilateral adaptive DBS)."
"An adaptive system like the one being tested here could offer an effective alternative and may also limit adverse effects of traditional deep brain stimulation, but considerable testing remains to be done. "Here we have demonstrated the feasibility of adaptive deep brain stimulation," said Dr. Starr. "We are now planning larger, longer-term trials to determine how effective this system is in managing the symptoms of patients with Parkinson's disease.""
"Indeed, it is possible there could have been a floor effect for dyskinesia in this study since dyskinesia was mild for all conditions (see Table 3 ). Another possibility is that bilateral adaptive stimulation may be necessary for clinical benefit and that this is why we did not see a clinical improvement (since we tested only unilateral adaptive DBS). Another consideration is that our results apply specifically to STN DBS, which is currently the most commonly used target for DBS in PD."

The types of pairs are between <paper, news> and <paper, tweet>. Each pair is labeled for the degree of information similarity in the findings described by each sentence, on a scale from 1-5. This is called the Information Matching Score (IMS). The data was curated from S2ORC and matched news articles and Tweets using Altmetric. Instances are annotated by experts using the Prolific platform and Potato. Please use the following citation when using this dataset:

@article{modeling-information-change,
      title={{Modeling Information Change in Science Communication with Semantically Matched Paraphrases}},
      author={Wright, Dustin and Pei, Jiaxin and Jurgens, David and Augenstein, Isabelle},
      year={2022},
      booktitle = {Proceedings of EMNLP},
      publisher = {Association for Computational Linguistics},
      year = 2022
}

Supported Tasks and Leaderboards

The task is to predict the IMS between two scientific sentences, which is a scalar between 1 and 5. Preferred metrics are mean-squared error and Pearson correlation.

Dataset Structure

Data Fields

  • DOI: The DOI of the original scientific article
  • instance_id: Unique instance ID for the sample. The ID contains the field, whether or not it is a tweet, and whether or not the sample was manually labeled or automatically using SBERT (marked as "easy")
  • News Finding: Text of the news or tweet finding
  • Paper Finding: Text of the paper finding
  • News Context: For news instances, the surrounding two sentences for the news finding. For tweets, a copy of the tweet
  • Paper Context: The surrounding two sentences for the paper finding
  • scores: Annotator scores after removing low competence annotators
  • field: The academic field of the paper ('Computer_Science', 'Medicine', 'Biology', or 'Psychology')
  • split: The dataset split ('train', 'val', or 'test')
  • final_score: The IMS of the instance
  • source: Either "news" or "tweet"
  • News Url: A URL to the source article if a news instance or the tweet ID of a tweet

Data Splits

  • train: 4721 instances
  • validation: 664 instances
  • test: 640 instances

Curation Rationale

Science communication is a complex process of translation from highly technical scientific language to common language that lay people can understand. At the same time, the general public relies on good science communication in order to inform critical decisions about their health and behavior. SPICED was curated in order to provide a training dataset and benchmark for machine learning models to measure changes in scientific information at different stages of the science communication pipeline.

Considerations for Using the Data

Social Impact of Dataset

Models trained on SPICED can be used to perform large scale analyses of science communication. They can be used to match the same finding discussed in different media, and reveal trends in differences in reporting at different stages of the science communication pipeline. It is hoped that this can help to build tools which will improve science communication.

Discussion of Biases

The dataset is restricted to computer science, medicine, biology, and psychology, which may introduce some bias in the topics which models will perform well on.

Other Known Limitations

While some context is available, we do not release the full text of news articles and scientific papers, which may contain further context to help with learning the task. We do however provide the paper DOIs and links to the original news articles in case full text is desired.
