BMII: A Marketing Giant in the Making WEUJIGBMLLFVFC

Title: Investors
 Emerging Growth Stock Alert Blagman Media International: A Marketing Giant in the Making   Key Points about BMII: BMII projects a total run rate of between $80-100 million in 2002.  BMII currently manages an advertising and promotional campaign for MET-Rx, the nation's leader in sports supplements.  Century Media, BMII's pending acquisition target, is one of the nation's largest direct marketing firms, with a dozen Fortune 1000 companies as clients.   BMII has the exclusive rights to market and advertise the national video release of a four video collector's set of the best of "The Red Skelton Show." Company Name  Blagman Media International (OTCBB: BMII)Current Price$0.0012 (12 hundredths of one cent)52-Week High$0.5652-Week Low$0.0011Company BackgroundToday we have a look at a classic merge and conquer scenario in the $200 billion dollar Direct Response sector.  The conqueror-to-be is called BMII (Blagman Media International, Inc.) The new company will combine the talents and clients of some of the biggest names in the infomercial world under the Blagman name.  With its announced plans to acquire major companies such as Century Media Inc. and Wellworld Group Ltd., BMII has quickly established a gateway for major immediate revenue stream coupled with rapid internal growth.  A-List clients have included the likes of Proctor & Gamble, Kodak, Dainler-Chrysler, Black and Decker, Home Shopping Network, and TriStar.  Total combined billings for BMII upon the completion of its acquisitions are expected to run from $80 to $100 million dollars in 2002.  This will give BMII the financial leverage and the know-how to change the face of the Direct Response industry.Industry StatsAccording to the Direct Marketing Association (DMA), U.S. direct marketing expenditures , currently at $191.6 billion, are expected to continue to grow annually at 7.1% from 2002 until 2005.  Moreover, U.S. sales revenue due to direct marketing is estimated to reach more than $1.8 trillion for 2001. Through 2005, such sales are estimated to grow by 9.6% annually to reach $2.7 trillion.   Again- Direct Response will cause $2.7 trillion (estimated) in sales by 2005.  This figure goes to show the effectiveness of direct marketing as well as the likelihood that demand for Direct Response will continue to grow over the years.BMII's Growth StrategyRecognizing the opportunity for strategic consolidation in the Direct Response industry, the management of Century Media and Blagman decided to utilize BMII to facilitate the acquisition strategy.  Through its public position, BMII assumed the lead role in the financing and negotiated the acquisition for a combination of stock and cash  The company's senior management and board will consist of a combination of senior managers from both companies.  Currently, no other direct independent competitor to BMII is in the field of Direct Response having the breadth and depth of its combined enterprises.  At present, 99% of the pure play infomercial business is privately held.  And for good reason.  The margins offered by Direct Response sales are three and four times greater than traditional bricks-and-mortar retail. Profit potential that makes BMII a stock with tremendous upside.    BMII CEO Robert Blagman understands the Infomercial sector.  Says Blagman,  "The primary purpose of these reverse mergers was to make BMII public and create a new BMII, a vehicle with which to build a media-buying infrastructure.  BMII will streamline operations, combine miscellaneous expenses, and create synergies within this larger structure to increase economies of scale and lower costs-per-eyeball for their clients."In ConclusionGiven its accomplishments and current plans, BMII appears to have great upside potential in the exciting infomercial market.  Blagman Media International has demonstrated is ability to capture substantial clients, as evidenced by its impressive client base.  The acquisitions of Century Media and Wellworld will provide BMII with an even larger client base with plenty of experience under its wing.     With an expected $80-100 million in billings for 2002 and the prospect of additional mergers, acquisitions, and new ventures, BMII gives investors plenty to look at given its price of just fractions of a penny per share.

meta analysis with multilevel data

2002-01-18 Thread Stefan Thau

Hello,

i have got a problem concerning computing effect sizes in meta
analysis: Does anybody know meta analytic studies using data
originating primary from multilevel data? If they dont report the
simple correlation matrix, does anybody know how to compute the ES(r)
from the coefficients reported in studies using multilevel analysis?

Greetings, Stefan

Hi!
Does anybody know of a reference for what CATPCA in SPSS (v10) does
and how it does it? I contacted SPSS but they don't even bother to
answer.
Thanks

Thanks Rich, most informative, I am trying to determine a method of
comparing apples to oranges - it seems an improtant thing to try to
do, perhaps it is impossible .

I am trying to
determine which is better, glycemic index or carbohydrate total in
predicting glycemic load (Glycemic load=glycemic index*carbohydrate).

my results as a matrix:

GI load  GI  Carb
GI load  1.000
GI   .5331.000
Carb .858.1241.000

So it seems that carb affects GI load more than does GI.. but this is
on ALL foods.. (nobody eats ALL foods so cannot extrapolate to human
diet) but I don't think you're allowed to do this kind of comparison
as Carb and GI aretotal different values:

I suspected that you would be allowed to make the comparisons if you
use Betas, ie. measure how many standard deviation
changes of GI and  Carb it requires..  If it takes a bigger standard
deviation of Carb then you could say that it is more likely that carb
has a bigger effect on glycemic load.

you seem to suggest that even using standard deviation changes, you
cannot compare  apples to oranges.  Which sounds right but is
dissapointing..

Millionaire?

2002-01-18 Thread zedd99

Hi

This is your chance to get rich!

I only started this a few weeks ago and have already made hundreds of
dollars, which  means I am going to make thousands all Tax free. And YOU
will to.
It really is simple just follow the instructions, I know you don't believe
it but you'll be making money by Christmas for very little outlay or effort!

The following is what I received, IT DOES WORK even in Europe.

Dear Friend and Future Millionaire,
My wife received this e-mail and forwarded it to me to review. We've both
read completely through it and have been in contact with some of the
individuals listed below.
We think it's an excellent opportunity that is well worth the small
investment of time and money, and believe that you will, too! CRH

AS SEEN ON NATIONAL TV:

Making over half million dollars every 4 to 5 months from your home for
an investment of only $25 U.S. Dollars expense one time
THANKS TO THE COMPUTER AGE AND THE INTERNET !

BE A MILLIONAIRE LIKE OTHERS WITHIN A YEAR!!!
Before you say ''Bull'', please read the following. This is the letter you
have been hearing about on the news lately. Due to the popularity of
this letter on the Internet, a national weekly news program recently
devoted an entire show to the investigation of this program described below,
to see if it really can make people money. The show also investigated
whether
or not the program was legal.
Their findings proved once and for all that there are ''absolutely NO Laws
prohibiting the participation in the program and if people can -follow the
simple instructions, they are bound to make some mega bucks with only $25
out of pocket cost''. DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT
THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING BETTER THAN EVER.
This is what one had to say: ''Thanks to this profitable opportunity. I
was approached many times before but each time I passed on it. I am
so glad I finally joined just to see what one could expect in return for
the minimal effort and money required.
To my astonishment, I received total $610,470.00 in 21 weeks,
with money still coming in."
Pam Hedland, Fort Lee, New Jersey

Here is another testimonial:

"This program has been around for a long time but I never believed in it.
But one day when I received this again
in the mail I decided to gamble my $25 on it. I followed the simple
instructions and walaa .. 3 weeks later the money started to come in.
First month I only made $240.00 but the next 2 months after that I made
a total of $290,000.00. So far, in the past 8 months by re-entering the
program, I have made over $710,000.00 and I am playing it again. The
key to success in this program is to follow the simple steps and NOT
change anything.''

More testimonials later but first,

The glycaemic index is calculated as the area under the blood
glucose curve for the two hours (or 3 hours for diabetics) after ingesting
enough of a food to include 50 grams of carbohydrate, divided by the same
area after ingesting 50 grams of pure glucose, expressed as a percentage.
In some cases a reference food other than glucose is used.

If the area under the curve is the glycaemic load you are studying I
would expect the model
 Glycemic load=glycemic index*carbohydrate
to fit the data very well when the carbohydrate content is near 50 gm,
providing all the glycaemic indices have been calculated on the same basis.
Using correlations or beta coefficients as you are doing is appropriate
when linear relationships are involved, but not to test for goodness of fit
to this model.
What would be of interest would be a plot  of the difference between
the predicted glycaemic load and the observed value,against carbohydrate,
especially for carbohydrate values far from 50 gm. If I have a meal of
mainly of eggs or meat, the total carbohydrate content is very low, so the
glycaemic load calculated from the formula may be wrong.
One difficulty with the whole Glycaemic Index approach is that there
is not, as far as I know, any way of calculating the glycaemic load from
foods like cheese,eggs and meat. If the body needs glucose, it will be made
from fat and protein foods.
It is not surprising that it could be hard to persuade volunteers to
ingest 8500 grams of processed cheese, containing 50gm of carbohydrate, in
order to determine its glycaemic index  :-)
 I would like to see another index constructed giving the glycaemic load
produced by 100 gm of each food, rather than the load produced by that
amount of food which contains 50gm of carbohydrate.

cell-counts question

2002-01-18 Thread Wei Wang

Dear Friends,

Here is an exam question which I don't know how to do. Can anyone help me?

The question is "a biostatistician was asked to analyze some data
regarding cell counts, and the values were reported like 6.27x10^7,
72.5x10^7, 3.42x10^7, etc. rather than using the data exactly as
reported, the biostatistician used the values as 6.27, 72.5, 3.42, etc.
what effect does this have on estimation of mean and standard deviation?
What effect does this have on hypothesis testing about the mean? Why?"

Thank you very much for your help.

Christine,
