Other key findings from the study: Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage.
Consequently, the implementation of checked baggage fees resulted in reduced likelihood of on-time departures as long as the carry-on baggage limits were loosely enforced.
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. Other key findings from the study: Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage. This shift resulted in a lower demand for airport labor-intensive, back-end operations such as baggage handling and security checks, which are shared resources across airlines.
Indeed, checked baggage fees led to more and heavier bags brought as carry-on into the cabin . Consequently, the implementation of checked baggage fees resulted in reduced likelihood of on-time departures as long as the carry-on baggage limits were loosely enforced. The passengers can also check more than two bags, however these extra-bags have always incurred additional fees, thus our discussion reduces to their behavior regarding the first two checked bags.

Ge and Schnable found that the software's estimates of plant size correlated strongly with their own measurements of plant weight, leaf area and water use efficiency. The methods required to establish those baseline values help illustrate why the RGB and hyperspectral imaging techniques should prove so useful, the researchers said. But teasing apart a plant's water weight from its new biomass growth - and subsequently determining how efficiently each plant turned water into new tissue - required multiple steps that ultimately destroyed the plant.
Total NIR reflectance appears to be influenced by leaf thickness in addition to water content, introducing confound- ing variation ( .

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.
Our research also sheds some light on the decisions made by a very operationally focused airline.
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.
Our findings highlight factors, such as the effect of carry-on bags, that need to be incorporated in designing incentive schemes. Our research also sheds some light on the decisions made by a very operationally focused airline. When the other airlines started charging for one checked bag, Southwest Airlines' decision to not charge for bags went against their high operational service level strategy as their relative departure delay performance initially decreased.

Those particular cases aside, every set M s corresponds to a certain input s but also to a certain position of the agent in space. Even if sensations s depend on the environment, the sets M s are thus environmentindependent. All the possible sets M i have a specific structure that can be captured to build an internal representation of the external agent's configuration.

In other words, taxi drivers had plumper memory centers than their peers.
Full-time taxi drivers had significantly greater grey matter volume in the posterior hippocampus than retired taxi drivers, who had greater volume in this region than the non-taxi driver retired control participants (figure 6d ).
Researchers noticed that a part of the brain called the hippocampus was much larger in these animals than in similar species that did not secret away their snacks. In other words, taxi drivers had plumper memory centers than their peers. It seemed that the longer someone had been driving a taxi, the larger his hippocampus, as though the brain expanded to accommodate the cognitive demands of navigating London's streets.
In line with the pattern of behavioural tests, it seems that the structural brain changes observed in taxi drivers in our previous studies may also reverse in retired taxi drivers. Full-time taxi drivers had significantly greater grey matter volume in the posterior hippocampus than retired taxi drivers, who had greater volume in this region than the non-taxi driver retired control participants (figure 6d ). Clearly, increased numbers of participants are required to confirm these findings.

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.
Another possible explanation is that price-sensitive customers of those airlines that charged for one checked bag started flying Southwest instead.
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. Other key findings from the study: Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage.
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. While it is obvious that additional passengers generate additional revenues for an airline, it is less obvious that more passengers represent an increased likelihood of departure delays.

Similar to the one checked bag fee policy, the theory does not offer a clear direction of the impact of the first two checked bags fees policy on departure delays, and hence we let the data dictate the correct hypothesis: Better relative performance as measured by departure delays is achieved when charging for the first two checked bags versus charging only for one checked bag. Worse relative performance as measured by departure delays is achieved when charging for the first two checked bags versus charging only for one checked bag.

Showing these figures and tables can also foster productive conversations about how generation, gender, and status affect perceptions of appropriate mobile phone use in formal and informal settings.
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. Among their findings: Three out of four people -- 76 percent -- said checking texts or emails was unacceptable behavior in business meetings.
It also equips instructors and trainers with a current set of statistics about norms of civility associated with various mobile phone behaviors in formal and informal meetings. Business communication instructors and trainers can use the tables and figures in this article to help business students and professionals gain awareness of some of the dramatic generational and gender differences. Showing these figures and tables can also foster productive conversations about how generation, gender, and status affect perceptions of appropriate mobile phone use in formal and informal settings.

Many of the participants said the immersive "presence" while using VR allowed them to focus better. "This leads to the possibility that an immersive virtual environment could enhance learning and recall by leveraging a person's overall sense of body position, movement and acceleration," said Catherine Plaisant, Senior Research Scientist in University of Maryland Institute for Advanced Computer Studies.
The HMD condition was found to have 8.8% improvement in recall accuracy compared to the desktop condition, and this was found to be statistically significant. This suggests an exciting opportunity for the role of immersive virtual environments in assisting in recall.

The number of baggage-related complaints per 1,000 passengers dropped as airlines' departure delay performance improved once most charged for checked bags.
The coefficient for the Bag-Fee indicator variable which indicates one checked bag fee as being implemented, is negative and statistically significant (-1.8701; p<0.0001).
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.
The results of the estimation of our Tobit1 model are shown in Table 6 14 . The coefficient for the Bag-Fee indicator variable which indicates one checked bag fee as being implemented, is negative and statistically significant (-1.8701; p<0.0001). This indicates that when the flights encounter departure delays, the implementation of one checked bag fees reduces SpAdj-Departure-Delay by 1.8701 minutes (when a delay occurs) versus no implementation of these fees.

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.
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.
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. "It's not free in an operational sense," Arikan says.
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.

This notion could be better defined by looking into functions that link motor commands to changes in stimuli that are external to the agent.
In some sense, the sensory manifold S describes the agent's internal experience of its translation in space, and is the only information it can gather about space.
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. "He suggested that the coincidence in the sensory input may play a crucial role."
This result was expected, as the dimensionality of the manifold S is determined by the number of degrees of freedom during exploration . In some sense, the sensory manifold S describes the agent's internal experience of its translation in space, and is the only information it can gather about space. However, S depends dramatically on the environment: the same exploratory movements performed in a different environment E will yield another sensory manifold S , which is totally different from S (see Fig.

"These additional second laws, can be thought of as saying that there are many different kinds of disorder at small scales, and they all tend to increase as time goes on," said co-author Professor Michal Horodecki (Gdansk).
In one regime one can cause an apparent violation of the usual second law, through a process of embezzling work from a large system which remains arbitrarily close to its original state.
In other words, just like larger systems, small systems also tend to become more disordered. "These additional second laws, can be thought of as saying that there are many different kinds of disorder at small scales, and they all tend to increase as time goes on," said co-author Professor Michal Horodecki (Gdansk). The researchers found additional measures of disorder, all different to the standard entropy, which quantify different types of disorder.
We further find that there are three regimes which determine which family of second laws govern state transitions, depending on how cyclic the process is. In one regime one can cause an apparent violation of the usual second law, through a process of embezzling work from a large system which remains arbitrarily close to its original state. These second laws are not only relevant for small systems, but also apply to individual macroscopic systems interacting via long-range interactions, which only satisfy the ordinary second law on average.

With a national sample of more than 550 full-time working professionals, the study reveals what business professionals perceive as acceptable, courteous or rude use of mobile phones in the workplace.
One of the more interesting findings was the major gender gap in perceived appropriateness of mobile phone actions.
Saying "Excuse me" to take a call didn't cut it: over 30 percent still found it to be rarely/never appropriate during informal/offsite lunch meetings. With a national sample of more than 550 full-time working professionals, the study reveals what business professionals perceive as acceptable, courteous or rude use of mobile phones in the workplace. The researchers first identified the most common grievances people had about smartphone use among their colleagues, including browsing the Internet and checking text messages.
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.

With the new research, scientists can definitively say that London taxi drivers not only have larger-than-average memory centers in their brains, but also that their intensive training is responsible for the growth.
Clearly, more work is required to establish whether the effects we have described here in relation to taxi drivers generalize beyond the domain of memory and the hippocampus.
These navigational demands stimulate brain development, concludes a study five years in the making. With the new research, scientists can definitively say that London taxi drivers not only have larger-than-average memory centers in their brains, but also that their intensive training is responsible for the growth. Researchers noticed that a part of the brain called the hippocampus was much larger in these animals than in similar species that did not secret away their snacks.
These effects can be positive and negative, with increased expertise and grey matter volume in some brain regions occurring in tandem with decreased performance on other tasks and decreased grey matter volume in neighbouring brain areas. Clearly, more work is required to establish whether the effects we have described here in relation to taxi drivers generalize beyond the domain of memory and the hippocampus. In particular, longitudinal studies will be crucial to explore the nature and consequences of skill acquisition.

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.
Moreover, during DBS at typical frequencies (i.e.130-10 Hz), if dyskinesia is present, the narrowband gamma oscillation occurs reliably at half the stimulation frequency , possibly because of neuronal entrainment (Figure 1A and 1C) .
The device differs from traditional ones in that it can both monitor and modulate brain activity. 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.
It is not strongly modulated by voluntary movement and is distinct from the canonical broadband gamma changes that occur in motor cortex during voluntary movement. Moreover, during DBS at typical frequencies (i.e.130-10 Hz), if dyskinesia is present, the narrowband gamma oscillation occurs reliably at half the stimulation frequency , possibly because of neuronal entrainment (Figure 1A and 1C) . Since this signature of dyskinesia is not disrupted by voluntary movement and occurs in a predictable frequency range, it is a promising control signal for adaptive DBS.

The research, published in the journal Proceedings of the National Academy of Sciences, reveals that on very small scales there is actually a whole family of 'second laws', which can lead to unexpected and counterintuitive phenomena.
Conversely, it is easy to see that the only process that conserves energy for an aribtrary state must commute with the Hamiltonian.
It tells us that a hot cup of tea in a cold room will cool down rather than heat up; that even the most efficient machines will lose some energy as heat; and more prosaically, that a house will gradually get messier over time rather than tidying itself. The research, published in the journal Proceedings of the National Academy of Sciences, reveals that on very small scales there is actually a whole family of 'second laws', which can lead to unexpected and counterintuitive phenomena.

What one means by close will determine which family of second laws apply, and in the subsequent statement we invoke the most stringent conditions, namely closeness in terms of work distance, Note that the demand that the unitary commutes with the total Hamiltonian implies that energy is conserved. Conversely, it is easy to see that the only process that conserves energy for an aribtrary state must commute with the Hamiltonian. We emphasize that the equivalence of this paradigm to others has already been addressed in .

Table 3 shows the perceived appropriateness of these various mobile phone behaviors during formal meetings at the workplace.
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. Among their findings: Three out of four people -- 76 percent -- said checking texts or emails was unacceptable behavior in business meetings.
The intensity of these comments was stronger when talking about what managers do. Table 3 shows the perceived appropriateness of these various mobile phone behaviors during formal meetings at the workplace. More than three quarters of respondents considered making or answering a call (87.1%), writing and sending texts or emails (84.0%), checking texts or emails (76.0%), and browsing the Internet (75.7%) as rarely or never acceptable in formal meetings.

"Not surprisingly, millennials and younger professionals were more likely to be accepting of smartphone use, but they might be doing themselves a disservice," Cardon said.
In the informal meeting setting (see Model 2 in Table 5 ), the following variables were significant predictors: age, gender, and region.

The number of baggage-related complaints per 1,000 passengers dropped as airlines' departure delay performance improved once most charged for checked bags.
Tobit regression model is appropriate here.
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.
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 researchers found additional measures of disorder, all different to the standard entropy, which quantify different types of disorder.
One can make a previously impossible transition possible by adding work in the form of the pure state ψW which will scale each point by an amount e −βW horizontally [5] . The above criteria should not be applied to the system of interest alone, but the system plus any additional resources which are used to enable the transition.

In a sense, the traditional second law only holds on average.
These second laws are not only relevant for small systems, but also apply to individual macroscopic systems interacting via long-range interactions, which only satisfy the ordinary second law on average.
"Even while individual parts of a system may become more ordered, the overall entropy of the total system (a measure of disorder) increases." In a sense, the traditional second law only holds on average. 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.
In one regime one can cause an apparent violation of the usual second law, through a process of embezzling work from a large system which remains arbitrarily close to its original state. These second laws are not only relevant for small systems, but also apply to individual macroscopic systems interacting via long-range interactions, which only satisfy the ordinary second law on average. By making precise the definition of thermal operations, the laws of thermodynamics take on a simple form with the first law defining the class of thermal operations, the zeroeth law, as derived here, emerging as a unique condition ensuring the theory is nontrivial, and the remaining laws being a monotonicity property of our generalised free energies.

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.
Thus, our findings also support the notion that Southwest's marketing strategy of being the only major U.S. airline not charging for the first two checked bags is in line with their historical operations oriented strategy. use BTS data on 10 major airlines in the 1995-2001 period on Fridays on the 1,000 busiest routes, and find that multimarket contact has a positive effect on arrival delays, causing delays on the ground, more in the form of gate departure delays rather than time spent on the runway. Using over 800,000 individual flights scheduled between 50 major U.S. airports in January, April, and July of 2000 finds that the prevalence and duration of arrival delays are significantly greater on routes where only one airline provides direct service, and that weather, congestion, and scheduling decisions have a significant contribution to arrival delays.

Assuming the same heuristics as in Proposition 2, any discrete logarithm in K can be computed in a time bounded by max(q, k) O(log k) .
Since solving this variant of the discrete logarithm is now within the capacity of current computers, relying on its difficulty for cryptographic applications is therefore no longer an option. This work is still at a theoretical stage and the algorithm still needs to be refined before it is possible to provide a practical demonstration of the weakness of this variant of the discrete logarithm. Nonetheless, these results reveal a flaw in cryptographic security and open the way to additional research.
Since any polynomial in q and k is absorbed in the O() notation in the exponent, we obtain the following result. Assuming the same heuristics as in Proposition 2, any discrete logarithm in K can be computed in a time bounded by max(q, k) O(log k) . In the first one, the finite field admits a sparse medium subfield representation, where q and k are almost equal.

First, using different image bands in the hyperspectral cube, plants can be more accurately segmented from the background and leaves can be accurately distinguished from stems (which is quite challenging with a RGB or NIR image). Second, hyperspectral images are capably of capturing the full spectral signature of plants, allowing more advanced analytical tools such as PLSR for modeling of leaf biochemical properties. Based on these previous knowledges, hyperspectral imaging is suggested as a powerful tool in plant phenotyping to complement RGB analysis (to obtain plant chemical traits in addition to morphological traits).

Virtual Reality helped patients recall old memories by providing new stimuli difficult to achieve, due to ill health, or inaccessible within a secure environment. They found that people remember information better if it is presented to them in a virtual environment. "This data is exciting in that it suggests that immersive environments could offer new pathways for improved outcomes in education and high-proficiency training," said Amitabh Varshney, Professor of Computer Science, in a survey published in the journal Virtual Reality.
However, participants were susceptible to disorientation if their starting-out views were different between their training and testing. The authors concluded that training in the virtual and real-world environments likely used similar cognitive mechanisms. They found that users in a HMD were better able to keep track of the objects by rotating their heads as compared to using a joystick.

"By showing that virtual reality can help improve recall, it opens the door to further studies that look at the impact of VR-based training modules at all levels -- from elementary school children learning astronomy to trauma residents acquiring the latest knowledge in lifesaving procedures," Varshney says.
Virtual environments that mirror the scene of the crime could provide superior assistance in recall by placing the victim back into such an environment.
The UMD team believes this study will lay the groundwork for other scientific inquiry on the value of VR and AR for education. "By showing that virtual reality can help improve recall, it opens the door to further studies that look at the impact of VR-based training modules at all levels -- from elementary school children learning astronomy to trauma residents acquiring the latest knowledge in lifesaving procedures," Varshney says. "We believe the future of education and innovation will benefit greatly from the use of these new visual technologies."
Such findings of contextdependent memory have interesting implications for virtual environments that have not yet been fully explored. Virtual environments that mirror the scene of the crime could provide superior assistance in recall by placing the victim back into such an environment. -Hypothesis 1: The participant memory recall accuracy will be higher in the HMD condition as compared to the desktop condition due to the increased immersion.

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.
Our findings highlight factors, such as the effect of carry-on bags, that need to be incorporated in designing incentive schemes.
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. "It's not free in an operational sense," Arikan says.
While the reduction in the number of checked bags may indeed have resulted in savings due to lower labor costs for handling checked bags, our findings suggest that the resulting increase in the quantity of bags carried-on may have had a detrimental effect on the airline's costs through a decrease in their on-time departure performance. Our findings highlight factors, such as the effect of carry-on bags, that need to be incorporated in designing incentive schemes. Our research also sheds some light on the decisions made by a very operationally focused airline.

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.
In some sense, the sensory manifold S describes the agent's internal experience of its translation in space, and is the only information it can gather about space. However, S depends dramatically on the environment: the same exploratory movements performed in a different environment E will yield another sensory manifold S , which is totally different from S (see Fig. Consequently, it is difficult for the agent to extract knowledge about space -which should be independent of the state of the environment -from exteroceptive experience.

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." The results consistently showed that people will take a utilitarian approach to the ethics of autonomous vehicles, one emphasizing the sheer number of lives that could be saved. 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.
As usual, the perceived morality of the sacrifice was high, and about the same whether the sacrifice was performed by a human or by an algorithm (median = 70). When asked whether they would agree to see such moral sacrifices legally enforced, their agreement was higher for algorithms than for human drivers (p < 0.002), but the average agreement still remained below the midpoint of the 0-100 scale in each scenario. Agreement was highest in the scenario where algorithms saved 10 lives, with a 95% confidence interval of 33-46.

Since solving this variant of the discrete logarithm is now within the capacity of current computers, relying on its difficulty for cryptographic applications is therefore no longer an option. This work is still at a theoretical stage and the algorithm still needs to be refined before it is possible to provide a practical demonstration of the weakness of this variant of the discrete logarithm. Nonetheless, these results reveal a flaw in cryptographic security and open the way to additional research.
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)). As a consequence, our algorithm is asymptotically faster than the Function Field Sieve algorithm in almost all the range previously covered by this algorithm. Whenever α < 1/3, our new algorithm offers the smallest complexity.

If their active participation in the organization of the data in virtual memory palaces makes a meaningful difference, then that could be further useful in designing interaction-based virtual environments that could one day assist in far superior information management and recall tools than those currently available to us. Yet another interesting future direction of research could be to compare elements of virtual memory palaces that are highly personal versus those that could be used by larger groups. Much as textbooks and videos are used today for knowledge dissemination, it could be possible for virtual memory palaces to be used one day for effective transfer of mnemonic devices among humans in virtual environments.

By using cognate terms for basic vocabulary items, we could compare terms that were homologous across languages and had retained a common meaning. Restricting our analysis to basic vocabulary items helped to limit the problem of semantic shift, where cognate terms take on new meanings in some descendant languages. It also helped ensure that we had comparable data for each of our language pairs: each of the languages had nearly all of the basic vocabulary items recorded but had varying amounts of general lexicon available in other databases (28).

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.
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. These survey results seem to indicate that women professionals hold different norms of civility as far as mobile phone use during informal meetings.

Dramatic age gap: Younger professionals were nearly three times as likely as older professionals to think tapping out a message over a business lunch is appropriate -- 66 percent of people under 30 said texting or emailing was okay, compared to just 20 percent of those aged 51-65.
On the other hand, strong majorities of employees above 41 years of age consider these actions as inappropriate.
Higher-income professionals had less tolerance for smartphone use in business meetings. Dramatic age gap: Younger professionals were nearly three times as likely as older professionals to think tapping out a message over a business lunch is appropriate -- 66 percent of people under 30 said texting or emailing was okay, compared to just 20 percent of those aged 51-65. Chances are, just having your phone out is offending somebody: A full 20 percent of professionals said simply having your phone out at a business lunch is rude.
Strong majorities of younger employees (21 to 30 years old) considered checking text messages and emails, answering calls, and even writing text messages and emails as appropriate. On the other hand, strong majorities of employees above 41 years of age consider these actions as inappropriate. This seems to indicate major generational differences.

The results showed an 8.8 percent improvement overall in recall accuracy using the VR headsets, a statistically significant number according to the research team.
The next steps will be to identify and characterize what elements of virtual memory palaces are most effective in eliciting a superior information recall.
"This data is exciting in that it suggests that immersive environments could offer new pathways for improved outcomes in education and high-proficiency training," says Amitabh Varshney, professor of computer science and dean of the College of Computer, Mathematical, and Natural Sciences at UMD. The results showed an 8.8 percent improvement overall in recall accuracy using the VR headsets, a statistically significant number according to the research team. In post-study questionnaires, all 40 participants said that they were completely comfortable -- and adept -- in navigating a desktop computer to access information, yet all but two said they preferred the immersive VR environment as a potential learning platform.
Our study provides a tantalizing glimpse into what may lie ahead in virtual-environment-based tools to enhance human memory. The next steps will be to identify and characterize what elements of virtual memory palaces are most effective in eliciting a superior information recall. It will be valuable to study how the addition of translation impacts information recall in a virtual memory palace.

Differences in synchronous activity likely reflect timelocking of the brain areas to stimulus features, as well as to actual content and events in the movie .
These similar kinds or synchronized signals were found in brain areas that are connected with the early-stage processing of visual stimuli, detection of movement and persons, motor coordination and cognitive functions. The results imply that the contents of the movie affected certain brain functions of the subjects in a similar manner," explains Kaisu Lankinen the findings of her doctoral research. With the help of MEG and new analysis methods, investigation of significantly faster brain processes is possible and it enables detection of brain activity in frequencies higher than before.
These findings demonstrate the capability of the proposed methodology to uncover cortical MEG signatures from single-trial signals that are consistent across spectators of a movie. Differences in synchronous activity likely reflect timelocking of the brain areas to stimulus features, as well as to actual content and events in the movie . Emotional video clips, compared with non-emotional ones, increase intersubject synchronization of voxel-wise fMRI time courses in many brain areas, for example in the dorsal attention network .

The number of baggage-related complaints per 1,000 passengers dropped as airlines' departure delay performance improved once most charged for checked bags.
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.
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 grouped into 'low-cost' versus 'legacy' carriers, however, we find opposite effects: the departure performance of the low-cost airlines became worse while it improved for the legacy carriers. 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.

These new second laws are generally not noticeable except on very small scales, at which point, they become increasingly important. It tells us that a hot cup of tea in a cold room will cool down rather than heat up; that even the most efficient machines will lose some energy as heat; and more prosaically, that a house will gradually get messier over time rather than tidying itself. The research, published in the journal Proceedings of the National Academy of Sciences, reveals that on very small scales there is actually a whole family of 'second laws', which can lead to unexpected and counterintuitive phenomena.
While macroscopically, only a single second law restricts transitions, we find that there are an entire family of more fundamental restrictions at the quantum level. At the macroscopic scale, and for systems with short range correlations, this entire family of second laws become equal to the ordinary second law, but outside of this regime, these other second laws impose additional restrictions on thermodynamical transitions.

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.
We show that, at the aggregate level, the airlines that began charging for one checked bag saw a significant relative improvement in their on-time departure performance in the 35-day period afterwards, compared to the airlines that were not charging for a checked bag during the same time period.
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. Other key findings from the study: Charging for the first or second checked bag improved on-time departure performance for all major airlines--including Southwest Airlines, which does not charge for the first two bags--because it creates savings due to a cultural shift among US passengers to travel with less baggage.
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. We show that, at the aggregate level, the airlines that began charging for one checked bag saw a significant relative improvement in their on-time departure performance in the 35-day period afterwards, compared to the airlines that were not charging for a checked bag during the same time period. When grouped into 'low-cost' versus 'legacy' carriers, however, we find opposite effects: the departure performance of the low-cost airlines became worse while it improved for the legacy carriers.

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.

Moreover, if autonomous vehicles actually turned out to be safer than regular cars, unease over the dilemmas of regulation "may paradoxically increase casualties by postponing the adoption of a safer technology." Empirically informed The aggregate performance of autonomous vehicles on a mass scale is, of course, yet to be determined.
Our findings suggests that regulation may be necessary, but at the same time counterproductive. Even though people seem to agree that everyone would be better off if AVs were utilitarian (in the sense of minimizing the number of casualties on the road), they all have a personal incentive to ride in AVs that will protect them at all costs. Accordingly, if both selfprotective and utilitarian AVs were allowed on the market, few would be willing to ride in utilitarian AVs, even though they would prefer others to do so.

"Here we have demonstrated the feasibility of adaptive deep brain stimulation," said Dr. Starr.
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.
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."
The zoomed in views of state changes in Figures 3c and 4b indicate that changes in classifier state were appropriately triggered by changes in gamma power. 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.

"This leads to the possibility that a spatial virtual memory palace -- experienced in an immersive virtual environment -- could enhance learning and recall by leveraging a person's overall sense of body position, movement and acceleration," Plaisant says.

The above studies show that compared to a purely mental mnemonic, a graphics desktop setup is better in assisting retention and recall.

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.
Their modeling approach indicates that the way in which airlines have been implementing baggage fees has more direct impact on controlling customer behavior than segmenting customers. Our study is the first to show empirically that baggage fees do seem to have influenced customer behavior, and that the effect depends on the type of airline. Unlike who posit that pricing the baggage separately induces customers to exert effort (i.e., to reduce the volume of checked baggage) and thus lowers the airline's costs, we find that this practice also induces customers to increase the volume of carry-on baggage, which does not lower the airline's costs.

Neither patient, males in their 60s diagnosed with Parkinson's seven and eight years earlier, reported feeling changes in stimulation. Researchers saw energy savings of 39 percent and 45 percent in the devices when using the adaptive algorithms.
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).

This notion could be better defined by looking into functions that link motor commands to changes in stimuli that are external to the agent.
A more realistic scenario, in which these manifolds are estimated purely on the basis of unlabelled sensorimotor data, is described in .
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. "He suggested that the coincidence in the sensory input may play a crucial role."
Note that the naive agent does not know this Jacobian, and that it is introduced here only to accelerate the simulation.

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 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.
Thus, for a company like Southwest Airlines which has a long history of being one of the best in its industry for operational performance and customer satisfaction, the decision of not charging AirTran Airways' passengers for the first two checked bags appears to be in line with their operational strategy. Ultimately, operations managers need to be involved in the discussions about marketing initiatives such as this one to evaluate the operational impact of marketing initiatives. 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.

This means that it is able to solve increasingly large discrete logarithm problems, while its computing time increases at a far slower rate than with previous algorithms. The computation of discrete logarithms associated with problems that are deliberately made difficult for cryptographic applications is thus made considerably easier. Since solving this variant of the discrete logarithm is now within the capacity of current computers, relying on its difficulty for cryptographic applications is therefore no longer an option.
Until recently all the cases had a sub-exponential complexity of type L(1/3), similar to the factorization problem. For larger values of q that stay below the limit L q k (1/3), our algorithm loses its quasi-polynomial nature, but still surpasses the Function Field Sieve. A first major progress was the realization that the DLP in finite fields can be solved in subexponential time, i.e.

Even at more informal business lunches, the majority of people thought writing a text message is rude -- 66 percent said writing or sending a text message is inappropriate. Men were nearly twice as likely as women to consider mobile phone use at a business lunch acceptable. More than 59 percent of men said it was okay to check text messages at a power lunch, compared to 34 percent of women who thought checking texts was appropriate.
Overwhelmingly, taking or making calls during meetings were the most commonly cited examples, with more than one half of employees who commented about meetings stating they had recently observed this behavior and considered it disrespectful. Writing and reading text messages or emails followed, with roughly one third of the employees citing these actions as recent examples of disrespectful phone use. Roughly one fourth of employees had observed recent examples of employees checking incoming calls or allowing their phones to ring that they thought were rude.

So it seems possible that with the globalisation made possible through the Internet, the English language should be changing at a faster rate than ever before. Whether that's the case, we're certainly seeing a lot of new additions to dictionaries, and a lot of those new additions are slang terms with which your average Internet denizen will be pretty familiar. This quarter's update shows that contemporary culture continues to have an undeniable and fascinating impact on the language."
Similarly we have carefully selected sister pairs with known relationships, whereas a whole-tree approach would require us to make assumptions about the more distant relationships between the ancestral lineages that gave rise to these contemporary populations. We have selected only pairs of languages where the relationships are well established and there is no evidence of replacement or blending of populations, avoiding populations with complicated settlement histories. Thus, the sister-pairs approach represents a conservative approach to the data that minimizes the assumptions that we must make about the history of the languages and the mechanisms of population and language change.

The environment-independent definition of space can be approached by looking into the functions that link the motor commands to changes in exteroceptive inputs.
"These concepts are instead developed over time, as useful tools that help them to make sense of the vast sensorimotor data they are constantly exposed to. As a consequence, a frog's notion of space will most likely differ from that of a bat, which will in turn differ from that of humans. Probably none of these.
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. In a sufficiently rich environment, the kernels of these functions correspond uniquely to the spatial configuration of the agent's exteroceptors.

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.
Approximately 63% said that they would not text message during meetings. The authors concluded that although mobile phone use in meetings is becoming more acceptable, it is still generally considered rude, inappropriate, or distracting during most meetings. We found that the literature falls short in several ways in identifying how mobile phone behaviors at meetings are perceived as appropriate or not.

This leads us to the possibility that a spatial virtual memory palace, experienced in an immersive virtual environment, could enhance learning and recall by leveraging the integration of vestibular and proprioceptive inputs (overall sense of body position, movement, and acceleration) ).
The results showed an 8.8 percent improvement overall in recall accuracy using the VR headsets, a statistically significant number according to the research team. In post-study questionnaires, all 40 participants said that they were completely comfortable--and adept--in navigating a desktop computer to access information, yet all but two said they preferred the immersive VR environment as a potential learning platform. The questionnaire also found that only two people said they felt "uncomfortable" using VR.
Lastly, place cells in the hippocampus activate in specific spatial locations, independent of orientation, providing an internal representation of the environment . This leads us to the possibility that a spatial virtual memory palace, experienced in an immersive virtual environment, could enhance learning and recall by leveraging the integration of vestibular and proprioceptive inputs (overall sense of body position, movement, and acceleration) ). This study found that the users who used a graphics desktop environment as the basis for their method of loci performed better than those using a mental scene of their choice, and those who were not instructed on a memory strategy did not perform as well as those who were instructed to use the memory strategy.

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.
The ordinary second law just corresponds to the non-increasing of one of these free energies, with the remainder imposing additional constraints on thermodynamic transitions.
In a sense, the traditional second law only holds on average. 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. In other words, just like larger systems, small systems also tend to become more disordered.
In particular, we find a family of free energies which generalise the traditional one, and show that they can never increase. The ordinary second law just corresponds to the non-increasing of one of these free energies, with the remainder imposing additional constraints on thermodynamic transitions. We further find that there are three regimes which determine which family of second laws govern state transitions, depending on how cyclic the process is.

These navigational demands stimulate brain development, concludes a study five years in the making.
In line with the pattern of behavioural tests, it seems that the structural brain changes observed in taxi drivers in our previous studies may also reverse in retired taxi drivers.
A map of its streets looks more like a tangle of yarn that a preschooler glued to construction paper than a metropolis designed with architectural foresight. These navigational demands stimulate brain development, concludes a study five years in the making. With the new research, scientists can definitively say that London taxi drivers not only have larger-than-average memory centers in their brains, but also that their intensive training is responsible for the growth.
It may be that with a longer period of retirement, performance on tests such as the Rey Figure would normalize entirely. In line with the pattern of behavioural tests, it seems that the structural brain changes observed in taxi drivers in our previous studies may also reverse in retired taxi drivers. Full-time taxi drivers had significantly greater grey matter volume in the posterior hippocampus than retired taxi drivers, who had greater volume in this region than the non-taxi driver retired control participants (figure 6d ).

The research, published in the journal Proceedings of the National Academy of Sciences, reveals that on very small scales there is actually a whole family of 'second laws', which can lead to unexpected and counterintuitive phenomena.
What's more, one needs to be more precise about what one means by a cyclic process.
It tells us that a hot cup of tea in a cold room will cool down rather than heat up; that even the most efficient machines will lose some energy as heat; and more prosaically, that a house will gradually get messier over time rather than tidying itself. The research, published in the journal Proceedings of the National Academy of Sciences, reveals that on very small scales there is actually a whole family of 'second laws', which can lead to unexpected and counterintuitive phenomena. "Even while individual parts of a system may become more ordered, the overall entropy of the total system (a measure of disorder) increases."
At the macroscopic scale, and for systems with short range correlations, this entire family of second laws become equal to the ordinary second law, but outside of this regime, these other second laws impose additional restrictions on thermodynamical transitions. What's more, one needs to be more precise about what one means by a cyclic process. Here, we show that this is not the case in the microscopic regime, and we therefore needs to talk about "how cyclic" a process is when stating the second law.

Phenotypic data collected from plants grown in the field is arguably the most informative for guiding plant breeding efforts .
Second sight Ge and Schnable also showed that conventional RGB imagery from the phenotyping system can be used to estimate the daily growth of corn plants - and how efficiently they use water to stimulate that growth - during their first few weeks of development. Ge and Schnable found that the software's estimates of plant size correlated strongly with their own measurements of plant weight, leaf area and water use efficiency. The methods required to establish those baseline values help illustrate why the RGB and hyperspectral imaging techniques should prove so useful, the researchers said.
Advancement in plant phenomics would enable more effective utilization of genetic data, and ultimately lead to novel gene discovery and improved crop yield and quality in the field.
