Women more likely to avoid harming even a single person, even if it results in thousands of deaths, research finds

Although females rationally evaluate the outcomes of actions the same as males, females make different decisions about their actions, according to recent research. Females are more strongly influenced by emotional aversion to causing immediate harm than are males, even when they believe their less harmful actions will result in greater overall harm, such as in hypothetical situations about stopping mass killers by killing or torturing them first.

“Gender differences on moral dilemmas which pit utilitarianism against deontology, seem to be driven primarily by differences in affective reactions to harm-doing, and very little, if at all, by differences in terms of cognitive evaluations of outcomes,” Dr. Rebecca Friesdorf of Wilfred Laurier University in Ontario, Canada told The Speaker.

“In other words, in this context, men and women seem to differ little in terms of how much they rationally consider the end result, but much more in terms of their emotional response to harming a single victim.”

The team of scientists, which also included members from the University of Cologne and the University of Texas, looked at data from 6,100 participants who had participated in research about high-stakes moral dilemmas, which included decisions that would result in death, lies, abortion and animal research. They team sought for differences in moral judgements between the sexes.

The team used a statistical procedure to rate and quantify the nature of the judgments.

“Although there is little evidence for gender differences in cognitive processing,” commented Friesdorf, “gender differences in affective processing are common and robust. For example, men and women score equally high on need for cognition, and gender differences in cognitive ability tend to be rather small. Yet, women tend to experience stronger emotional responses than men; they are more persuaded by messages appealing to emotion; they score higher on measures of empathic concern; and they are more adept at identifying with other’s emotional states.”

In the recent research, the team found that females were less willing to support the killing of Adolf Hitler or torturing a bombing suspect to find explosives, although they reasoned that the actions would save more lives overall.

The researchers suspect that the reason for this is that females are more emotionally averse to the idea of themselves causing harm than are men.

“We suspect that this is the case based on prior research, specifically Greene’s (2007) dual-process model of moral judgment,” said Friesdorf. “A large body of evidence supports this model, in which rejecting harmful actions in moral dilemmas is associated with affective processes, and accepting harmful action that maximizes outcomes is associated with cognitive processes. For example, manipulations that vividly highlighted the harm caused by action increased deontological judgments, whereas reducing negative affect reduced deontological judgments. Conversely, manipulations enhancing rational decision-making increased utilitarian judgments, whereas cognitive load slowed and time pressure reduced utilitarian judgments. Moreover, brain regions associated with affect were more active when people made deontological judgments, whereas brain regions associated with working memory were more active when participants made utilitarian judgments.

“Thus, a wide range of evidence supports the dual-process model of moral judgment where affective reactions to harm motivate harm rejection regardless of the outcomes — consistent with deontological ethics — and cognitive evaluations of outcomes motivate harm acceptance when harm leads to better overall outcomes — consistent with utilitarian ethics.”

Although not the subject of their recent work, Friesdorf offered us some thoughts about how the differences in female and male decision-making might have effects in the real world.

“Although I’m not currently aware of any research which investigates gender differences in these inclinations (deontological/utilitarian) in more every-day type scenarios/dilemmas, I suspect that it is possible that they do generalize to some situations. For example, perhaps in an employment context, female managers might be more likely than male managers to be empathic/sensitive toward the potential suffering of a single employee, and therefore less likely to make a choice which greatly benefits a large group of employees, if it involves dealing great harm to the single individual.”

The report, “Gender Differences in Responses to Moral Dilemmas,” was completed by Drs. Rebecca Friesdorf, Paul Conway, and Bertram Gawronski, and was published in Personality and Social Psychology Bulletin.

New senses easily added to mammal brain, beginning with geomagnetoception

Researchers at Tokyo University have added a new sense to the brains of rats. The procedure was relatively simple and the rats integrated the new sense — a geomagnetic compass — quickly. Blind rats given the new sense were soon able to navigate laboratory mazes almost as well as sighted rats. Because of the ease with which the new sense was added, researchers think many other senses can be added to the mammal brain, expanding the “colorfulness” of our experience and abilities.

“Perhaps we do not make full use of our brain.” Dr. Yuji Ikegaya of the University of Tokyo told The Speaker. “The limitation does not come from our lack of effort, but it does come from the poor sensory organs of our body. The body restricts the brain; that is, the brain has over-evolved compared to the current performance level of the body. The real sensory world must be much more ‘colorful’ than what you are currently experiencing.”

The research team added a geomagnetic compass to the senses of blind mice, and the mice were able to navigate a lab maze almost as well as mice that were not blind.

“Although I do not believe that the brain is always plug-and-play ready, the brain seems to be highly adaptive and flexible so that it can perceive and use even non-inherent sense,” said Ikegaya.

The connectivity point for the new sense did not have to be specific, Ikegaya told us.

“We arbitrarily inserted two electrodes into the visual cortex. The locations of stimulation seemed unlikely to be important, because stimulation of other brain areas also worked similarly. Our head-mountable geomagnetic sensor device was designed to connect a digital compass, a microchip used normally in smart phones, to two tungsten microelectrodes for intrabrain stimulation. It is also equipped with a manipulator of stimulation intensity and a rechargeable battery. The device weights 2.5 g and thus head-mountable. During exploration of an animal, it automatically detects the head direction and thereby generates electrical stimulation pulses — for example, when the animal faces the geomagnetic north or the south.”

Ikegaya pointed to the latent, incredibly flexible potential of the mammal brain — potential that has so far been largely untapped. He expressed hope that there were many abilities that could be added to our brains.

“We expect that humans can expand their senses through artificial sensors — ‘supersensory’ organs — including geomagnetism, ultraviolet, radioactive rays, humidity, ultrasonic, radio wave, pheromones etc. Sensing sunlight UV may be important for reducing skin cancer. Also, ultrasonic and radio wave may enable a next-generation form of human-to-human communications.”

One of the most notable possibilities suggested by the study is improvements in the navigation abilities of blind people.

New surface technology could provide invisibility from sonar to any object

Usually, sound reflects off of the objects it encounters, bouncing some sound waves back in the direction from which they came — this phenomenon is familiar in the application of sonar. No technology has yet been developed that can provide sonar invisibility to any object, but a team of Singaporean researchers recently proposed a novel material surface that could do just this by directing sound waves around an object to be sent off in one direction on the other side.

The technology shares some features with topological insulators, which direct the flow of electrons along a surface, and builds on recent advances in our understanding of a class of electronic waves called “topological edge states.”

Dr. Baile Zhang
Dr. Baile Zhang

“‘Topological edge states’ are a kind of state originally found in electronic topological insulators and quantum Hall systems,” Dr. Baile Zhang of Nayang Technological University, who led the research, told The Speaker. “They are technologically promising because they are immune to backscattering from defects and disorders, similar to superconductors. But later it was found that topological edge states can also be constructed with classical waves, like electromagnetic waves and mechanical vibrations.

The proposed surface prevents sound waves from propagating through the middle of a two-dimensional triangular lattice of spinning metal cylinders. The periodic pattern of the lattice creates a sonic band gap, like other topological insulators, but it creates something else, too.

The edges of the proposed material support propagation in only one direction around the perimeter of the object. Thus, the edge states can guide sound waves with high precision.

New surface technology could provide invisibility to any object from sonar (3)

“The circulating fluids can break time reversal symmetry, meaning that a wave moving forward will perceive differently from another wave moving backward,” Zhang told us.”So, we can utilize it to realize waveguiding only in one direction without reflection, no matter how large the defects are.”

That is what is key for creating stealth technology of this sort, said Zhang — the regularity of the material and guiding the flow of sound waves. “An irregular protrusion is one of the biggest headaches for stealth engineers,” he said, but coating any object with an acoustic topological insulator would guide sound waves around it in a single direction and hide that object from sonar.

“I think the most important thing is a picture of acoustic waves that can circumvent any defect or disorder, immune to backscattering from them,” said Zhang of the research.

The report, “Topological Acoustics,” was completed by Zhaoju Yang, Fei Gao, Xihang Shi, Xiao Lin, Zhen Gao, Yidong Chong, and Baile Zhang, and was published online on APS Physics.

Ebola in Liberia could could be eradicated by June, according to new “method of plausible parameter sets”

Ebola in Liberia could could be eradicated by June, according to new method of plausible parameter sets

The Ebola virus, which has taken the lives of over 4,000 people in Liberia over the past year, could be wiped out completely by the beginning of summer. It is not a foregone conclusion, but it is a realistic possibility, according to the researchers responsible for a new forecast based on new highly inclusive models.

“I think the elimination of human-to-human transmission of Ebola in Liberia by summer is probable and can be expected,” Dr. John Drake, the associate professor at the UGA Odum School of Ecology who led the project, told The Speaker. “However, as with all infectious diseases near elimination, the last mile will be one of the toughest and it would be foolish to count on elimination before it has been finally achieved.”

The work was undertaken by a joint team of ecologists from the University of Georgia and Pennsylvania State University.

“Our new method of model fitting — called the ‘method of plausible parameter sets’ — aims to quickly provide a back-of-the-envelope working model that primarily rules out inconsistent scenarios rather than quantifying the relative likelihood of alternative consistent scenarios,” Drake told us.

Their model not only estimates Ebola’s reproductive number (the number of new cases that could result from currently infected people), but also infection and treatment setting, variations in individual infectiousness, hospital capacity and burial practice changes.

“The factors in our study are inter-related. Hospital capacity and a willingness of infected persons to be admitted are mutually reinforcing as hospitals can do nothing to isolate patients if infected persons are unwilling to be recognized and a willingness to be treated is useless without facilities that can safely treat. The safe, dignified burial of the deceased was also crucial to reducing the average number of secondary infections from a case. I believe all three were necessary for containment.”

It does not include some other factors, however. The team limited their model to what they felt was most important, ignoring superfluous data in order to achieve a usefully “intermediate complexity.”

The models used data from earlier Ebola outbreaks, factored for underreporting, in-hospital and burial transmission, and infection control effectiveness. They then added data from July through September about new cases and changes in the factors of transmission. Branching processes — a mathematical formulation that provides for all possible outcomes based on the proportion of their probabilities — was used in the models.

“Branching process theory is an area of mathematics that can be used to model contagion, reproduction, and other population dynamic phenomena that have a probabilistic component to them,” Drake explained. “We found it to be useful in this case because we could derive many of the properties of interest — like the average change in infection — from considerations about the constituent processes — like transmission from nursing care or during funeral preparations and proceedings.”

One of the biggest takeaways from the Liberian outbreak, Drake commented, was the decisions and actions of those who undertook to fight it.

“Containment required collective coordinated action. Governments, non-governmental organizations and the Liberian people are to be commended for acting swiftly and assertively. Our model predicts that if they had not, things might have gotten much worse very quickly.”

The researchers expect that their model will also be useful for future outbreak scenarios, as will their new method for model fitting.

BRIEF – Novodevichy Convent, a large Moscow monastery situated around 5 km from the Kremlin, was the site of a large fire Sunday night. The building has been under repair, according to Bulletin Echo, and the fire may have begun with one of the scaffolding towers.

The fire began at after 10:30 p.m. Moscow time. Fire fighters arrived shortly thereafter.

The area has been cordoned off. The cause of the blaze is not yet known, and authorities have not yet made any statements.

Initially, rumors spread on social media that the fire had taken place at the Kremlin.

Novodevichy Convent is a perhaps the best known cloister of the Russian capital. It was founded in 1524 by Vasili III, the Grand Prince of Moscow, and has remained intact since the 17th century. The name can be translated as New Maiden’s Monastery.

In addition to being a famous tourist attraction in its own right, the cemetery attached is the location of the graves of former Soviet leader Nikita Khrushchev, former President Boris Yeltsin, writer Anton Chekhov, and other famous Russian deceased.

South Sudan: Lakes State Ministry of Agriculture receives 31,000 liters of fuel

Share this

RUMBEK, South Sudan — Lakes State Minister of Agriculture Philip Kot Job has received 31,000 liters of fuel for tractor cultivation for 2015.

“I have informed the farmers of Lakes State that we have received our fuel, which had been in Juba for over a year,” the minister said.

“We have received now 31,000 liters and we are trying to put this quantity into a deposit so that it is kept until April 2015.”

Farmers will be organized and will be supported with this fuel, the minister said.

He added that this fuel is mainly to deal with issues of food security because we are the region is trying to improve the lack of food and is bound to bring food items from outside into the state.

“The policy of national government — which says agriculture comes first — that is why we are serious to see that this year is for cultivation,” he explained.

“So our people must really concentrate on cultivation, starting from H.E. the Governor to the lowest citizen in the state here,” the minister added.

“This is information for all the citizens of Lakes State that we are now serious that this year is good for digging so that we can free ourselves from salvation.”

He added that those who have their own tractor should come and have fuel up at any time.

Job also advised Lakes State’s citizen to concentrate on agriculture rather than fighting.

“We will not be friend to hunger this year, but if we are not serious it will get away from us because our thinking is too low in terms of farming,” he explained.

“The first priority in my plans as Minister of Agriculture is cultivation; we will not be stable if agriculture is not reorganized in this country,” he said.

Immune cells learn “numbers” from past infections, allowing the body to better deal with future infections of all types

Immune cells learn from past infections, allowing the body to more deftly deal with future infections of all types

According to recent work conducted by a joint team of researchers from James Cook University, Charité-Universitätsmedizin Berlin, the Max Planck Institute for Infection Biology, the University of Heidelberg, and the National Institutes of Health, the body’s cells not only learn from the infections they encounter, becoming better able to deal with various infections throughout life, but can also remember numbers.

Dr. Andreas Kupz,
Dr. Andreas Kupz

“For a very long time we have tried to classify memory immune cells on overall function and morphology and have tried to group them based on such features,” James Cook University’s Dr. Andreas Kupz, co-author on the study, told The Speaker. “Although this might make the wealth of information and detail more digestible, it becomes more and more clear, not just from our study, that such ‘average’ is just not good enough anymore. There is a huge heterogeneity even within individual memory immune cell subsets and in the future the focus must be much more directed towards the single cell level.”

T-helper cells, which were the focus of the recent research, help other immune cells by releasing cytokines, messenger substances.

“Our findings demonstrate that every individual T helper cell stably memorizes not only the type but also the amount of a certain cytokine it produces based on the information it receives during an initial infection,” Kupz told us. “Although we did not test the effect of this quantitative cytokine memory on a different infection, it is likely that the amount of cytokine produced will not change because the level of cytokine is predetermined through the amount of a ‘master transcription factor’ within the nucleus of the cell.”

However, T-helper cells don’t learn in the same way we understand people to learn.

“‘Learning’ in this situation is probably best translated with ‘memorizing,’ which in itself is a feature of learning. The learning occurs through maintaining a defined amount of the transcription factor that controls the production of certain cytokines. The cell-specific fine adjustments of this process is still not entirely understood but may involve the control of cytokine receptor expression and/or the activity of downstream signal transduction molecules.”

“Furthermore, we found epigenetic modifications at both the locus of the cytokine and the controlling transcription factor. Hence, we hypothesize that a combination of multiple permissive and repressive epigenetic modifications at several regulatory sites imprints the stable cytokine memory.”

Although dealing with infections does strengthen the body’s ability to deal with later infections — which might be information that could factor into arguments in the current vaccination debate — Kupz was clear that his comments were not to be on the debate, and that vaccination is something he believes is very important and necessary.

“The immunological memory that is generated through exposure to vaccines does in fact often rely on similar ‘learning’ mechanisms. ”

“In my opinion the most important take home message from this study is not so much the applicability of our findings for health and disease but more the gain in overall knowledge about T cell biology,” Kupz speculated on how his work could contribute to the growing body of information about the role of T cells, and how it could potentially lead to strengthening specific immune reactions and to reducing the misdirected immune responses that cause inflammation.

JUBA, South Sudan — As motorbike riders protest the regulation of wearing helmets in Chad, ravaging the capital city N’djamena, and businessmen triple the price for helmets with strong resistance from the motorbike riders, it’s a different story in Juba south Sudan

From dusty roads to unshaded stages, rough roads to tarmac roads, hot weather to rainy seasons, polite customers to rude customers, drunk drivers to disciplined drivers. This is the way to go for many of the unemployed youth, between survival and starvation in Juba.

“Life has never been easy to my side. I wake up every morning and try to catch up with the early travelers who board to Uganda,” recounts one such motorcycle rider.

He is one of those who hustle in the bare heat of Juba since he set his feet in the South Sudanese capital. Since the slow evolution of motorcycles in Juba starting with the famous Senke Tembo brand and then the Ling ken/Hiadjin brands, TVs brand, and now the most-desired soft-cushioned Bajaj Boxer model.

People who came from the countryside have lived on petty jobs like building houses using muddy loam soil, most of whom had an East African educational background, which was a second thought in employment requirements to the Arabic background during the old Sudan days. Living up to the promise of buying a motorcycle seems a dream come true to most youth, who are employed in competitive and self-sacrificial jobs in these busy streets of Juba.

The cost of living is one they focus on, and the standard of living under the scorching sun depends on the ability to satisfy your customers’ needs with early morning motor checks, riding the rough dusty roads, dodging speeding vehicles which sometimes break traffic laws knowingly, though not on the list of vehicles to be given way, as are police, ambulance and fire-fighting vehicles. People move reluctantly and the own reckless riders of the well-known big blown heavy pair of short lovers (the Senke boys/Juba Boys) bending on one side of the cleanly maintained motorcycle with loud music speakers booming hip hop and accelerating as if it were the last race they will ever have, with the trademark sound of blocked exhaust pipes or an open exhaust with a wide cut.

Most of the riders do not have a driver’s license. But it is a relatively cheap way of living in Juba and provides a sufficient wage for their hard work, charging a fare averaging from five South Sudanese pounds for a shorter distance to over ten for longer distances, and basing the prices on the high prices of goods in Juba. The biggest happening that the bike boys always feel disturbed by is the frequent visits by the well-known South Sudan Motorcycle Boda-Boda Association (SSMBA), which they called the Abraham Men, to collect 50 SSP monthly for the parking stage — or what they called the rent fee.

“It’s often a struggle when they come. They try to take all the keys and demand the receipts of payments,” exclaims one rider who also said this always causes them to scratch their heads, as the money is not reinvested in the rehabilitation of roads.

The struggle gets harder and harder by the day, as all will be struggling to reach a minimum of 60 SSP per day, reaching out for rude customers who shout commands on a very hard knock voice and directing you to violate traffic laws to catch their appointments. Negotiating between vehicles and risking arrest from the traffic police, accused of causing most of the accidents in the city, and even the government designating some “no go” routes for the motorcycle riders, they all are struggling to live on the better side of Juba and wishing to get to a better job one day by feeding themselves on the streets of this sunny, hot and dynamic Juba city, putting bread on the table and never relaxing because of the demands of survival.

Whenever a disciplined and charming customer comes on board, gives a smile and says, “Take me to Konyo-konyo market,” then you can probably be sure that the day is a completely fine day for the family… Till then.

Red prince of my heart
That quenches my thirst for the history of a thousand years, In your presence sprouts the life force of knowledge
In the garden of my consciousness.
The eternal flame of the butter lamp that flickers in my eyes Is stoked by my sweat and blood.

The land of snows has entrusted everything to you, And you too
Fearlessly speak the word of truth
For the sake of our hopes and prayers.

Potala Palace!
The consciousness of my forefathers rests On your high throne.
I forever
Will decorate your pillars with golden rings.

But the fierce wind from the East
Has many times racked with tongues of flame Your tender form.

O great yogi, in whose heart swirls unadulterated compassion, You forever
Like the blood moving in my body
Will rise to face the challenge of history.

Embodying the integrity of a nation,
Even though you are hurt you lick your wounds And stand proud in all circumstances.
While the sharp fangs of a dark beast
A tailless dog pretending to be a lion
Utters empty threats from its cave.

Potala Palace!
The solitary hero, never changing. I forever
Will serve under your blessing.

Potala Palace!
From the first time I welcomed the sun and the moon Until when the circulation of my blood stops,
My loyalty to you in body, speech, and mind
Shall remain eternal.

Dig my grave and raise my barrow

By the Dnieper-side
In Ukraina, my own land,
A fair land and wide.
I will lie and watch the cornfields,
Listen through the years
To the river voices roaring,
Roaring in my ears.

When I hear the call
Of the racing flood,
Loud with hated blood,
I will leave them all,
Fields and hills; and force my way
Right up to the Throne
Where God sits alone;
Clasp His feet and pray…
But till that day
What is God to me?

Bury me, be done with me,
Rise and break your chain,
Water your new liberty
With blood for rain.
Then, in the mighty family
Of all men that are free,
May be sometimes, very softly
You will speak of me?
