Unstated questions, hidden answers

Am I colour-blind?
Some respondents to the previous post here and privately seem to think my view on academics had been too harsh.
Although I have not compiled a comprehensive analysis of every scientist or researcher around the world, one way to gauge the effectiveness of some action is to look for its results. Let's not forget, someone in their position does have the ear of an editor, convener, or program chef. So, where and when has someone confronted a public phenomenon grounded in ideology head-on through his or her expertise on the subject?
Then there is the anecdotal evidence. Such as the comments by Jennie Brockie, presenter of the SBS-TV Insight program. On the 12 Oct 04 the topic of the discussion was, "Is animal rights activism out of control?". According to Ms Brockie several scientists were invited to attend to give the research side of the story. They declined because they were intimidated by activists who sometimes went as far as issuing death threats. The point was made repeatedly in the program, with the two scientists who did appear confirming the situation.
Remarks by Islamic clerics or others who are more interested in the shock value than actual substance are not countered by the voices of reason. And if editors cannot bring themselves to accommodate the unsensational then why is there not a systematic pressure applied to them in the interest of a mature society?
A critical and objective analysis is of course in line with the principles of the Enlightenment, the antagonist of Middle Eastern ideologies from the very beginning. Currently it is deemed the height of political incorrectness to criticise the general denigration of Western and/or European culture.
Some days ago the London think tank Policy Exchange published the report "Living apart together". Muslims across Britain were surveyed on their attitudes towards the British and Westerners in general. Their own comments made reference to a crude anti-Western bias existing in society (pp 7, 16), the official policy of multi-culturalism was seen as making the situation actually worse by mostly denigrating its own (pp 24, 33), and the report's authors recognised that the ideals once introduced by the Enlightenment and now downgraded provide the cultural vacuum for extremism to flourish once again (p 92). I don't think Australia is that much different.
No-one expects intellectuals to fight it out on the streets. But their professional status also comes with the duty attached to preserve the cultural climate which gave them their positions in the first place.

Has science turned yellow?
There can be many reasons why something is misunderstood. Sometimes psychoanalysts have a field day.
The editor of a journal - both shall remain nameless - saw fit to reject a recent article about the worm program. The reason? As a "functionalist" I omitted important references to the field of functionalism, thereby evading the ongoing debate about the latter's tenets.
Why am I a "functionalist"? Throughout the article I had used the words 'functional' and its noun to describe a principle form of behaviour, compared to the behaviour's content (for instance, 'love' can be viewed as a functionality; one's love for a car is the instantiated content).
Nothing more, nothing less. Although explained in those terms, to that reader this was neither here nor there. Now it is true functionalism features large in the debates surrounding cognitive science and artificial intelligence. But it is a movement, if you will, which ultimately did not produce a viable model of how the mind works. Despite the often intricate hypotheses the resultant perspectives were insufficient to address the phenomenon of mind in a realistic, useful manner. Hence no reason to waste my time on it.
Why then jump to such a conclusion?
Well, it might have been a simple matter of a certain word capturing one's imagination in a rather indiscriminate fashion. But there could be more behind this.
How their mind works is a question that has occupied humans for ages. So you'd think somebody coming along and declaring "I know!" would be greeted with enthusiasm. Not necessarily.
Anyone claiming to have found the solution should then be able to address such matters as religion, culture, or ideology in a formal, objective manner. He or she should give a proper explanation why the Iraq war for example is such a disaster, or why Pacific island nations implode, or why it came to the street riots in France not so long ago.
Deep down this is understood of course, and so such a claim would consequently require the courage to engage with life out there, something an increasing number of academics are reluctant to do. What is left for public occasions such as debates on TV shows are the extremists, political players of any ilk, and interested lay people having to make do with random information. Conveners of such shows find it difficult to invite professionals who can provide some factual input as a balance.
It is much more comfortable to draw differential equations inside a cosy office, or to engage in sparkling word play at a lecture. Yet there is a world beyond those walls, and what one finds out there are hardened adventurers under many an exotic flag or no flag at all.
Lest you think I am exaggerating, just watch a politician's discomfort rise as soon as the topic turns to religion - an increasing likelihood these days.
Much better then to remain with the incestuous squabbles about this or that -ism and forget about reality. Edgar Allan Poe in his "The Masque of the Red Death" described it so well!
It is interesting to note that in the case of my work no-one has ever found an error in my observations, my deductions or conclusions, in my calculations or in my use of logic or in any line of my code. Instead, vacuous generalisations are used to hide from the world.

A plague of crows - dead or alive
Crows get rid of rotting food; they are good for the hygiene of the city, right? Well, read on:
One day in 2001 I stood in Brighton Road, Highgate Hill, Brisbane, and looked across the patch of land which is bounded by Appel Street, Vulture Street, Franklin Street, and back to Brighton. I counted 20 crows. As anyone can confirm standing in the same place this must be on the low side because of so many blind spots. Anyway, using a street directory it turns out that the patch measures 0.15 by 0.25km, or 0.0375sqkm; in other words, there were 20 crows per 0.0375sqkm.
If we look at the map of entire Brisbane and take an area which is defined in the southeastern corner by Shailer Park, in the southwest by Redbank, and in the northwest by Bray Park, we get a rectangle which has its northeastern tip over the water somewhere off Mud Island. But that's fine since we left out large sections in the east towards Redland Bay and in the north towards Redcliffe; therefore the resultant 1000sqkm would be on the conservative side. Dividing those 1000 by 0.0375 (the Highgate Hill patch) gives us 26,667, and multiplying this figure by 20 (the number of crows counted) results in 533,333 crows for the Brisbane area.
Now we know that crows can live to the age of 35, but assuming a median value of 25 years seems reasonable since we are dealing with animals in the wild. Therefore we can say that it takes approximately 25 years for over 500,000 birds to die off. Divide 533,333 by 25 and we get 21,333, which is the number of crows dying every year; this means 1778 crows per month. If the average crow weighs 0.55kg, the above amount translates to 978kg.
It is believed that in Brisbane the crow population has reached its plateau, although the last ten years saw a dramatic increase in their numbers. Let's say this happened five years ago, in which case every single month from about 2025 onwards the people of Brisbane will endure a mass of dead crow flesh to the tune of almost one ton spread across their city.
There you have it. The above assumes the birth and death rates are steady, but they are not if the population is still rising. This may well be the case because the human population is increasing and the main food source for the birds is the rubbish we generate. Then these figures are just the start and a larger fallout from their corpses is yet to come. And by the way, there are many areas where the pro rata crow numbers would be much greater. For example, there once was a colony of about 50 crows in one (!) of the trees at the University of Queensland.
Feel free to check the figures for accuracy.
By the way, so far there has been no response from the Lord Mayor or from Professor Jones.
And here's something else:
As it happens, on Friday 26th the Brisbane metropolitan daily, The Courier Mail, ran an article about sounds painful to humans, "Vomiting tops the sound of pain list". As the title suggests, regurgitating is the most repulsive of them all. Professor Trevor Cox from the University of Salford in the UK did not include crows in his survey, otherwise the birds' ability to simulate the gagging sound immediately preceeding the actual vomiting would have featured as well. It's part of their repertoire.

In the name of the Crow: human abuse
One example of an incongruent system sitting uncomfortably within a larger domain is the status of the Torresian Crow in Queensland, Australia, more particularly in the Brisbane metropolitan region.
These crows are a protected species because they are deemed to be indigenous and seen as a valuable player within the environment. Fines for killing the birds can reach up to A$225,000 or two years' jail. The official justification for their protection is based on the argument that the crows are scavengers which dispose of garbage and therefore contribute to a cleaner environment around the suburbs.
Over the years they have become an issue because of the loud noise they make. A single bird can produce up to 82 decibels, not far from the 85db considered to be harmful for humans under prolonged exposure. In more practical terms this means a crow 20m away from a window and cawing away makes it impossible to understand the other party on the phone. Naturally, there could be many more birds in nearby trees. In summer they begin their ruckus from about half past four in the morning onwards and so make sure humans within hearing distance get woken up regularly every day of the week. From then on during the ensuing daylight hours the noise can last for half an hour, one hour, or two hours etc depending on their whim. By the way, the decibel data come from Associate Professor Darryl Jones, Director of the Centre for Innovative Conservation Strategies at Griffith University, Brisbane, a staunch defender of the bird's current status.
The Torresian Crow occupies a region stretching from the tip of Cape York in Queensland down to northern New South Wales along the eastern seaboard (a north-south distance of nearly 3000km) and latitudinally right across the upper half of the continent to the coast of Western Australia, (details - you can even download its call there and test it out on yourself making sure the volume is up). Over the last ten years the numbers have increased dramatically in the greater Brisbane metropolitan area and a conservative estimate would put them at about 4-500,000. Therefore extinction is not exactly an issue.
Regarding their noise, although being woken up very now and then may not be that significant, having to endure this treatment day after day does affect the sleeping patterns of humans. Sleep deprivation has been identified as a form of torture by the United Nations and prolonged lack of sleep is considered detrimental to one's physical and mental well-being, comparable to illegal levels of alcohol in one's blood and even leading to psychotic states (details).
Let me state my personal interest in all this: I am one of those affected, but given their distribution across the Brisbane area there would be thousands of others in a similar situation (and no, as of now I haven't reached a psychotic state).
Furthermore, the Brisbane City Council issues several guidelines for noise levels that justify complaints. The maximum levels for inside the house are 20 to 30db, for daytime in a quiet residential street they are 35 to 45db, for a large busy office they are 50 to 60db, and for lawn mowers from 15m away they have been set at 70db - all well below the possible 82db from crows.
How then can an academic stand by his stance resulting in a situation that invited the label of torture by the UN and has been deemed leading to major pathological conditions by medical experts in the field? Or for that matter, how can a city council have a law against behaviour that goes against established standards when the culprits are human but actually enforces non-compliance through much more stringent legislation when even worse is committed by certain wildlife?
As to their assumed waste disposal function, what do cities do which have no crows, or what did Brisbane do before the numbers escalated? And in any case, in regions around the world where garbage is left for animals to deal with the state of hygiene overall is precarious precisely for that reason - exactly the opposite of the claims given to us by our local officials.
To answer these questions a letter each is sent to Professor Darryl Jones and the Lord Mayor of Brisbane, Campbell Newman, referring to the above.
It is rational to be concerned about the environment, but the movement has sprouted a form of religion. Without that idiosyncrasy the crow problem could have been dealt with by now.
Brisbane is by no means alone. Below are just a handful of links out of hundreds, if not thousands.

What's the main message?
When it comes to the sustainability and/or survival of a system, especially of the type addressed in the context of cognitive dynamics under Otoom, several criteria become apparent:
- the more harmonious the system is within itself, the greater the potential for growth; or, the larger the system the greater the need for congruence within its domains (in other words, rational thinking is favoured over ideology);
- it is a measure of a system's quality whether it is capable of organising itself according to the above;
- the larger the extent of a system's congruent domains, the higher the probability that useful information can be gathered, processed, and disseminated;
- in addition, the larger the extent the higher the probability of useful abstraction processes taking place, which in turn feed back into the general information stream;
- defining a system's value in terms of the above, its inherent potential is directly proportional to: (1) the environmental resources, (2) the number of functional elements, (3) the inherent variance of those elements, (4) the degree of connectivity between its elements, (5) the variance of its informational units (in other words, the units' granularity in relation to the entire information volume).
Expressed less technically it means that a large-scale population in a resource-rich environment, its members understanding each other with reference to commonly recognised standards, a well-organised infrastructure covering education, health, and welfare, a minimal amount of censorship, a self-administered control over the growth of ideology, and a lively language, are the recipe for long-term success.
All of these criteria are independent of what has been termed culture or race under conventional views. For that reason the term 'demographic' is preferred since it refers to what a domain actually does at the moment of observation, rather than what some label presumes it would do.
It shouldn't be too hard to find examples of viable systems and others more or less dysfunctional.
