Politics / Re: Violence In Plateau State: 13 Killed, 30 Houses Burnt In Berom Villages, Riyom by TheArbiter: 11:36am On May 03, 2012
naanmin: @Arbiter its becos d problem is always in Berom dominated areas! Wen it was happenin in Yelwa-Shendam it was always Hausas and Shendam pple. Did it mean Shendam pple had a problem? No it meant it was happenin in their domain!!

@naanmin Your reference to the Shendam issue is illuminating. But wasnt the problem in Shendam basically a political one that subsequently degenerated into violence. It is however noteworthy to see that it never reoccurred like the crisis in Jos and environs. In character, scale and duration the Jos crisis definitely takes the crown. I beg to differ, there is more to the Berom vs Fulani-Hausa issue than meets the eye. I do know Mangu, Shendam, Kanam, Wase, Lantang south and Quan pan contain significant populations of both Christians and Muslims and also different tribal mixes. Why is the violence not erupting in this areas?

A full discussion of the Jos crisis is not for the pages of this forum, infested as it is with all manner of bigots, tribalists, warmongers and separatists. I rarely reply to comments related to ethnic-religious issues except to inject facts, figures or perspectives into the discussion. Most people these days rarely see beyond the gore, blood and sentiments to proffer solutions to any problem in Nigeria. Ask anyone how America was able to meld different races into a formidable country on earth. The right answer, if the person isnt an ignoramus, is JUSTICE or the SENSE OF JUSTICE. I have read a considerable amount of research about the conflict in Plateau mainly because i have lost friends across both ends of the ethnic-religious divide, very good friends for that matter. I consider myself well informed about it. I take no sides but blame all. The Hausa's, Beroms, Fulani's and all other tribes involved in these killings are just MURDERERS pure and simple. They repeat it again and again because they can get away with it. It is a reflection of the general malaise that affects Nigeria as a whole.

YOUR TRIBE OR THE RICH AND POWERFUL CAN NEVER DO WRONG. This is the overriding rule in Nigeria and its tearing it to pieces.

Took the liberty of solving without waiting for your input since it was not very difficult.

For configuration A, the answer is 24secs.

For configuration B, the answer is 48secs.

Solution Logic:

In a time t, slow train travels x meters. In a similar time period fast train travels (500-x) meters and (1000-x) meters respectively for configurations A and B. Using your physics equation: S= Ut + (1/2at2). Terms in brackets = 0 since no acceleration. Hence:

slow train: x=30t
fast train: (500-x)=45t or (1000-x)=45t depending on configuration.

Substitute for x and solve. Dont forget to get your units right.
Education / Re: Someone Should Pls Help Me Out by TheArbiter: 10:14am On May 03, 2012
Your question is structured incorrectly. You need to clarify one issue. Take a look at the representations of the problem below. The letter D represents the train driver. Which of the configuration below best describes your question?

DCCCCCCCCCCCCCCCCCCCCCC Fast train --->
<--- DCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC Slow train

Configuration A.


DCCCCCCCCCCCCCCCCCCCCCC Fast train --->
<---- CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCD Slow train

Configuration B.

Has anybody ever questioned why its always Beroms against the Fulani and Hausa? Is it evident to all that there are more than 30 tribes on the plateau but only one is significantly involved in the so called ethnic-religious crisis?

True, lives have been lost on both sides of the ethnic-religious divide in the plateau crisis. But i find it suspicious that out of the over 30 tribes on the plateau, only one has a serious beef with the Fulani. Even the Tivs rarely have violence on the scale we see on the plateau despite their face offs with the Fulani. After the cannibalism they displayed of recent, i have have written off the Beroms off my list of civilized people and i stand to be corrected.

The Nigerian press has always been biased since inception along north-south, ethnic and religious lines. Infact, i rarely distinguish any difference between reports in papers and the NTA. Everything you read on newspapers is to be considered false or twisted until proven otherwise. That has been my attitude to newspapers and has been proven true 60% of the time. As a matter of fact irresponsible journalism can be adduced as the catalyst for a lot of the violence in the Nigerian state since inception (coupled with other factors).

It is only when you think that you liberate yourself. Passions and emotions has always been the African way of doing things and not logical thinking. It may be an intense way of life but it always fails 90% of the time.

May you see beyond your passions and emotions to the kernel of the idea i wanted to share through this post.

A language's functionality usually depends on programming skills level and its implementation (its ability to do what u want it to do efficiently). Its a relative thing depending on who you talk to; java, ruby,C++,C, perl or phyton programmer. The web content below ranks programming languages using usage and visibility stats from internet sources. The original link to the content below: http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html

TIOBE Programming Community Index for April 2012

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system.

Education / Improve Your Intelligence Quotient (IQ) by TheArbiter: 6:35pm On May 01, 2012
A recent study in the Proceedings of the National Academy of Sciences found that a particular memory game called Dual N-Back may actually improve a persons short term memory. The study indicates that by regularly playing the Dual N-Back game, it may be possible to increase almost anyone’s IQ (or more accurately, gF), which was previously thought to be unchangeable.

The Dual N-Back game involves remembering both a sequence of spoken letters AND a sequence of positions of a square at the same time, hence the term “Dual” in the game name. The “N” refers to how many sequences back you remember.

Food / If Beans Can Talk Would U Eat Dem? by TheArbiter: 5:09pm On Apr 30, 2012
A recent study in Israel asserts that bean plants can talk (communicate) with each other through their roots. Is it enough reason to stop eating beans?
read full article below.

Original Link provided: http://opinionator.blogs.nytimes.com/2012/04/28/if-peas-can-talk-should-we-eat-them/


Imagine a being capable of processing, remembering and sharing information — a being with potentialities proper to it and inhabiting a world of its own. Given this brief description, most of us will think of a human person, some will associate it with an animal, and virtually no one’s imagination will conjure up a plant.

Since Nov. 2, however, one possible answer to the riddle is Pisumsativum, a species colloquially known as the common pea. On that day, a team of scientists from the Blaustein Institute for Desert Research at Ben-Gurion University in Israel published the results of its peer-reviewed research, revealing that a pea plant subjected to drought conditions communicated its stress to other such plants, with which it shared its soil. In other words, through the roots, it relayed to its neighbors the biochemical message about the onset of drought, prompting them to react as though they, too, were in a similar predicament.

Curiously, having received the signal, plants not directly affected by this particular environmental stress factor were better able to withstand adverse conditions when they actually occurred. This means that the recipients of biochemical communication could draw on their “memories” — information stored at the cellular level — to activate appropriate defenses and adaptive responses when the need arose.
In 1973, the publication of “The Secret Life of Plants,” by Peter Tompkins and Christopher Bird, which portrayed vegetal life as exquisitely sensitive, responsive and in some respects comparable to human life, was generally regarded as pseudoscience. The authors were not scientists, and clearly the results reported in that book, many of them outlandish, could not be reproduced. But today, new, hard scientific data appears to be buttressing the book’s fundamental idea that plants are more complex organisms than previously thought.

The research findings of the team at the Blaustein Institute form yet another building block in the growing fields of plant intelligence studies and neurobotany that, at the very least, ought to prompt us to rethink our relation to plants. Is it morally permissible to submit to total instrumentalization living beings that, though they do not have a central nervous system, are capable of basic learning and communication? Should their swift response to stress leave us coldly indifferent, while animal suffering provokes intense feelings of pity and compassion?

Evidently, empathy might not be the most appropriate ground for an ethics of vegetal life. But the novel indications concerning the responsiveness of plants, their interactions with the environment and with one another, are sufficient to undermine all simple, axiomatic solutions to eating in good conscience. When it comes to a plant, it turns out to be not only a what but also a who — an agent in its milieu, with its own intrinsic value or version of the good. Inquiring into justifications for consuming vegetal beings thus reconceived, we reach one of the final frontiers of dietary ethics.

Recent findings in cellular and molecular botany mean that eating preferences, too, must practically differentiate between vegetal what-ness and who-ness, while striving to keep the latter intact. The work of such differentiation is incredibly difficult because the subjectivity of plants is not centered in a single organ or function but is dispersed throughout their bodies, from the roots to the leaves and shoots. Nevertheless, this dispersion of vitality holds out a promise of its own: the plasticity of plants and their wondrous capacity for regeneration, their growth by increments, quantitative additions or reiterations of already existing parts does little to change the form of living beings that are neither parts nor wholes because they are not hierarchically structured organisms. The “renewable” aspects of perennial plants may be accepted by humans as a gift of vegetal being and integrated into their diets.

Investment / Re: Any Hope On The Stock Market: Will It Ever Pick-up Again? by TheArbiter: 11:04am On Apr 10, 2012
I understand cashmentor's statement to imply the market growing to the levels it was 6 to 7 years ago anytime soon. To that, the answer is a capital NO. The reason being that the fundamentals of the Nigerian market still remains weak. Overall, the market still continues to loss money. However, the policies of the CBN, which have been widely criticized, remains a strong reason for the current faith in the market or it would have collapsed to levels lower than this. The current long view of the market sees a strong growth beyond 2015, barring any political mishaps during elections. The market would have seen a slow growth rather than decline at present but the lack of will by the Jonathan led administration to tackle industralisation, evident corruption and strengthen transparency within the market, remains a strong mitigating factor.

Feelamong represents a small class of stock market players called speculators. They make money based on correct guesses of market direction, buying and selling blocks of shares to make make a profit (or loss). The blocks of shares often traded represent 5% to 20% of a companies total shareholding. Though small, the influence of this transactions affect the pricing of the stock instruments. The yoyo nature of price movements to such transactions have also been touted as an indication of the market weakness. In developed economies, share prices fluctuate based on company performance while in Nigeria it is not so.

Many people have lost fortunes in the Nigerian stock market crash. I personally know a few. Most were victims because they never understood what it was all about. Like feelamong says understanding the market is essential to any1 intersted in it.

Education / Re: How JAMB Marks UTME Result Sheets by TheArbiter: 3:52am On Apr 07, 2012
@seudocode

The OMR can easily be programmed to perform NEGATIVE marking. Recall i said if the scanned answer option is translated to A-E, a comparison with preprogrammed data is done. Instead of scoring zero for wrong answers as i had previously stated, -1, -2, -0.5, etc could be programmed. However, I'm not very sure if the OMR can handle decimal values (0.1,0.5,etc) (i dont know everything) but it can definitely handle integer values (1,2,10,etc). If the OMR cant handle decimal values (which i doubt) the data admins can easily process negative marking on the results.

That said, i'm not aware if JAMB implements NEGATIVE marking. I would be speculating if i say yes though, some candidates have made such accusations. Similarly, i've heard some post-UTME candidates insinuating that some institutions (sorry not mentioning names) implement negative marking but it still remains to be proven.




@francis247

Could you try to be civil with ur statements next time. I have the penchant to ignore speech below the scale of civility.

As regards ur observation. Yes, JAMB seems to have undertaken to help sloppy candidates with custom preshaded JAMB Nos on result sheets. It requires JAMB to know which candidate is allocated to which venue so as to ensure its success. It also helps to minimize cheating. But given obvious issues that could arise (damaged sheets, logistics, etc) i doubt if it has been implemented nationwide. I decided to approach the issue from the well known perspective; the candidate shades everything required. It is my believe the explanation and approach may benefit most exam candidates (WAEC,NECO,etc), including post-UTME candidates, where the dangers i had enumerated is sure to occur.

There is no harm in generalizing i hope.

I dont work with or for JAMB so i cant tell u how to get ur cousins result form. Why not go to any JAMB office and ask.

As regards her performance, its a relative thing. Maybe she was a local champion (4give the nuance), she's now in the big league. Many brilliant students have wrote JAMB only to be shocked at the results they get. One thing i do know is dat JAMB questions are trickish. Also consider what i said about multiple shading. If u now add exam stress (Which occurs only mainly during exams and rarely during mock tests) to it, i believe most students performance can be explained.

P.S.: Exam stress is a term for the psychological state in which some students freeze, have stomach upset, bladder discomfort , sweat, shiver or shake, go cold or hot and are basically unable to think clearly or even answer d exam questions. It rarely happens outside a real exam environment. It has been attribute to the fear of failure. It usually happens when d first few questions students see are unknown to dem or difficult.

viccipedia: IF IT CAN DETECT A SCRATCH, IT MEANS IF YOU SHADE THE WRONG ANSWER, AND LATER ERASE IT AND SHADE THE CORRECT 1, IF THE ERASER DOES NOT TOTALLY ERASE THE PREVIOSLY SHADED ANSWER, IT MEANS THE OMR WILL MARK THAT NUMBER WRONG RIGHT?

CORRECT. That is why most answer forms are full of warnings and notices that you shade the correct answer only and that u completely erase faulty answers completely.

Note that the machine can be configured to recognize only very dark shadings (It can actually be configured to recognize shades of grey to black), but if this is done people like coded777 above will have problems of ungraded results.
Education / Re: How JAMB Marks UTME Result Sheets by TheArbiter: 10:35am On Apr 05, 2012
@coded777

As long as u use the recommended pencil and shade inside the option boxes provided the OMR reader will recognize it. The machine is programmed to recognize HB pencil dark markings. The paper used is special, it highlights the markings. A little unintentional mark, even a scratch is picked up by the machine.

A problem with the OMR machine (which is not due to it) is not be able to detect marks but being so good at it that multiple marks(by candidates making corrections) are easily detected (despited being erased) and scored zero by it.
Education / Re: How JAMB Marks UTME Result Sheets by TheArbiter: 7:50am On Apr 05, 2012
Common problems associated with JAMB results are enumerated below:

1. Multiple shading is a major cause of failure for most candidates. Bear in mind that the machine compares dark shadings in the boxes. If u correct an error witout completely rubbing off the dark pencil marks, the OMR reader rejects it. Also if you use a light pencil instead of the recomended one, the OMR reader will be unable to recognize it and grade u accordingly. Most students are usually unaware that somehow, maybe due to exam stress, even the brightest of them can be victims of multiple shading.

2. Wrong shading of jamb Nos will get ur results allocated to the person who has the JAMB No u incorrectly shaded. Even if the data admins were able to detect multiple results for the person whose No you incorrectly shaded, they are still unable to detect who you are to assign the result to you. This mistakes accounts for situations where some claim they wrote nothing in some subjects but still received marks. [s]Most students are usually unaware that somehow, maybe due to exam stress, even the brightest of them can be victims of multiple shading.[/s]

3. The vertical black boxes at the edge of the result form is very very important. If it is torn or damaged in any way promptly request another new result sheet. If it is damaged in any way the OMR reader will be unable to grade your form. The black Box marks guides the OMR scanner when it scans ur form.

4. Always request for the correct result form for your exam question paper. The OMR reader cares not if u were given result forms for combination A instead of combination C that appears on your exam question paper. It will mark your results against existing data for combination A, resulting in failure for you.

Education / How JAMB Marks UTME Result Sheets by TheArbiter: 7:31am On Apr 05, 2012
I admit this post might have been more useful before the UTME examinations. But i do think it may still be important to some people who require more info on how it is done.

The UTME result sheets are called document forms (or just forms). They are specially printed precision papers with dark vertical boxes on one edge and lots of blank boxes to be shaded in by candidates. The shaded forms are taken after the exams to large OMR readers (Click here to know more about OMR readers: http://en.wikipedia.org/wiki/Optical_mark_recognition) Which scan the forms at the rate of 1 to 5 seconds per form.

The OMR readers compare a preprogrammed darkness with that in the shaded box. If the shaded box mark darkness is greater than or equal to the programmed data, it is recognized as valid and interpreted. Based on the interpretation, the shaded box is translated as 0-9 or A-Z for alphanumeric boxes. For answer options it is translated to the specific option chosen; A-E. If the option matches the one in the program, 1 or 2 marks are awarded and zero awarded for a wrong answer. Now all this process takes just approximately 5 seconds max per form.

After all the forms have been scanned, it is fairly checked for integrity; 1% of the candidates forms are randomly selected, manually graded and checked with the OMR marked results to check for mistakes. This may also be done by randomly feeding checker forms during the marking process and subsequently checking to see if they were correctly graded. The checked results are then handed to the database admins who then process and upload it all in less than 12 hours into the master database. After the JAMB approval meeting ratifies the result, the online database is updated from the master database then activated to receive checking requests.

JAMB most times out of a sense of responsibility, analyzes the rejected results, especially for those with wrong exam Nos (Note incomplete exam Nos are difficult to rectify especially if there is more than 1 candidate affected for an exam venue), multiple shading, etc to assist such sloppy candidates. This accounts for some results being released after a month or two after results were first released. Results update may also be done where it is discovered the OMR reader was wrongly programmed or the data admins made mistakes during processing and upload.

The above operating procedure is basically similar to what WAEC, NECO and some universities post UTME exams currently use. I believe JAMB has the capacity to grade up to 3 million forms in 3 days.
