Mapping GOP Campaign Cash by Density
By Matt Stiles | April 4, 2016 November 17, 2016 Matt Stiles | Topics: Policy & Politics
The GOP presidential candidates collectively have raised more than $300 million in this election cycle, according to Federal Election Commission data. Here's a quick look at where several of those candidates — Jeb Bush, Ben Carson, Chris Christie, Ted Cruz, John Kasich, Marco Rubio and Donald Trump — collected the money.
Each dot on the maps (see update below) below represents at least $5,000 raised by zip code. The dots in each place are assigned randomly within the zip code boundaries, creating a density map (think Verizon vs. AT&T) for campaign donations* through Feb. 29.
Here's a (crowded) map with all the candidates. The dots were layered alphabetically, a method that unfortunately obscures some candidates at this scale, depending on the geography. Still regional differences are evident:
The former Florida governor raised large amounts of money, of course, from his home state, but also — as the perceived frontrunner for a time — from major population centers:
Carson raised a ton of money for someone who received relatively little love once voters started casting their ballots. His map shows he raised more from small locations throughout the country, not just the major population centers:
The New Jersey governor, understandably, raised a large proportion of his money from his home region:
The Texas senator raised money from all over the country, but he clearly has a financial base in Dallas-Fort Worth, Austin, San Antonio and Houston — the major population centers in his home state.
Like Christie, the Ohio governor tapped his donor base at home:
The Florida senator's map looks much like that of his frenemy, Bush:
The billionaire business man, who has relied largely on personal funds for his campaign, has raised very little money in checks larger than $200, as reflected in his map:
* To keep the analysis consistent for all campaigns, the maps were created with a data set that excluded individual donations of less than $200. The data include only donations to the candidates' campaign committees, not other political committees supporting them.
UPDATE (9:20 p.m. EST): Based on David's suggestion in the comments, I've changed the dot color in the individual maps so it's consistent. You can see the originals here: Bush | Carson | Christie | Cruz | Kasich | Rubio | Trump.

Candidate Fundraising vs. Super PAC Spending in January
By Matt Stiles | February 22, 2012 Matt Stiles | Topics: Uncategorized
From Huffington Post:
Reports about January's fundraising numbers, released on February 20, have focused on two narratives: Mitt Romney's limited fundraising and high burn rate and the role that super PACs are playing in an increasingly contested Republican primary. HuffPost decided to combine those narratives together to make a graphic of candidate and super PAC fundraising and spending in January.

Colbert and the Clouds
Stephen Colbert this week used word clouds — visual representations of word frequencies in selected blocks of text — to tell a story about his political action committee.
Colbert recently asked supporters to submit suggestions for the PAC's mission, and he wanted to visualize their responses for his television audience.
This version shows the most popular words in all the responses:
Then, Colbert (or presumably someone on his staff) weighted the cases to represent only responses by donors who gave at least $1.
The second version represents the responses Colbert "heard," I suppose making a point about the fact that corporate spending is now considered political speech.
Genius. Here's the full sketch.

Rick Perry: Fundraiser
Now that Texas Gov. Rick Perry, R-Texas, is officially in the presidential race, reporters are noting his campaign fundraising prowess as a possible strength that could propel him to the GOP nomination:
But it is a credential Mr. Perry is unlikely to highlight that could make him the most formidable entrant in the Republican race so far: he is among the top political fund-raisers in the country, with a vast network of wealthy supporters eager to bankroll his presidential ambitions, and he has the potential to energize Republican donors who have shown only limited enthusiasm for the candidates already in the race.
Indeed, Perry has raised more than $100 million in his decade-long tenure as governor, including $39 million in the his 2010 re-election effort, according to electronic campaign reports in Texas.
Here are his fundraising totals by year:
And a breakdown of how much he's raised from individual donors versus entities, such as law firms and political action committees:
Nine in 10 dollars collected by Perry came from Texas donors, but he has raised money from every state (darker shades represent higher dollar amounts):
Here's a map that visualizes totals donated per household in each state. You can see that Colorado, Delaware and Washington, D.C., gave at higher proportions than other states (except for Texas, of course):
Finally, here's a word cloud that highlights the most common donor occupations listed by Perry's campaigns over the years, eliminating the phrase "Best Efforts." The latter phrase is required in state law if a campaign can't identify a donor's occupation. (The Perry team has done that quite a bit over the years).

Financing Texas Elections: 2010
By Matt Stiles | January 20, 2011 Matt Stiles | Topics: Uncategorized
Another cross-post from my work blog:
The 2010 political campaigns are over, but looking back at the fundraising and spending that financed them is now fully possible thanks to records made public by the Texas Ethics Commission after Tuesday's filing deadline.
With this new data, which cover donations and expenditures from October 24 to December 31, we can now illustrate campaign activity for the full year. This column chart visualizes campaign activity, by day, for all candidate/officeholders and specific-purpose committees during 2010. Red spikes represent spending; blue spikes represent fundraising.
(View a larger version)
The graphic offers an interesting, though not necessarily unexpected, timeline of the campaigns, which spent about $180 million during the year — not including what third-party groups devoted to the various contests up and down the ballot. I've highlighted spikes in activity that correlate with high points of the campaign.
Notice spikes in the competitive Republican primary contest between Gov. Rick Perry and Sen. Kay Bailey Hutchison, as well as the Democratic primary between former Houston mayor Bill White and hair care magnate Farouk Shami. The largest came on Feb. 18, when Perry, Hutchison and Shami spent about $3.5 million on television advertising ahead of Election Day.
There's a similar spike before the general election contests including Perry and White, and all the competitive and expensive Texas House races. The largest jump came on Oct. 15, when Perry and Lt. Gov. David Dewhurst, who was fending off a challenge from labor leader Linda Chavez Thompson, purchased $5.1 million in television time.
Other events are highlighted, too. You'll see that fundraising jumped sharply on June 30, the mid-year filing deadline. It also spiked on Sept. 23, which was a deadline for the 30-day ethics filing, which is released Oct. 4. Another spike occurred on Dec. 11, the day before a fundraising moratorium before the 82nd legislative session.

Severe stress during pregnancy linked to schizophrenia
22 August, 2008 By Steve Ford
Pregnant women who endure severe psychological stress are more likely to give birth to a child that develops schizophrenia than other women, according to researchers.
US researchers looked at data from 88,829 people born in Jerusalem between 1964 and 1976.
The authors found the offspring of women who were in their second month of pregnancy during the height of the Arab-Israeli war in June of 1967 displayed a significantly higher incidence of schizophrenia over the following 21-33 years.
'The stresses in question are those that would be experienced in a natural disaster such as an earthquake or hurricane, a terrorist attack, or a sudden bereavement,' the authors said in the online journal BMC Psychiatry.
'The placenta is very sensitive to stress hormones in the mother, these hormones were probably amplified during the time of the war,' they added.

### E heti tanulmányunk
Ezsdrás 4; 5:1-5; Nehémiás 4; 6:1-13; Haggeus 1; 2Korinthus 6:14

>

> "De a zsidók vénein rajta volt Istenük szeme, így nem akadályozták meg őket az építésben, míg az ügy Dárius elé nem jutott, és amíg levélben nem válaszoltak rá" (Ezsd 5:5, ÚRK).

Ezsdrás könyvének 3-6. fejezete tematikus felépítésű és a templom újjáépítésével szembeni ellenállás különböző történelmi periódusait fedi le. A tematikus megközelítés ismeretében tisztábban láthatjuk az általános üzenetet.

Ezsd 7:1 verse említi először név szerint Ezsdrást. Kr. e. 457-ben történt érkezése után a dolgok megváltoztak, elkezdődött Jeruzsálem meg a falak újjáépítése – több hullámban. Nehémiás tizenhárom évvel később indult (akit Kr. e. 444-ben küldött el Artaxerxész), majd újrakezdték a fal építését. Az erős ellenállás dacára ötvenkét nap alatt befejezték a munkát (Neh 6:15).

Ezsdrás és Nehémiás könyveinek gyakran felbukkanó témája az Isten művével szembeni ellenállás. Nem meglepő, hogy a templom és Jeruzsálem újjáépítése ellenkezést és üldözést váltott ki. Bárhová tekintünk a mai világban is, látható, hogy szembeszegülnek az Úr művével. Sátán igyekszik oda hatni, hogy az evangélium ne terjedjen gyorsan, mert az fenyegetné az uralmát. Hogyan kezelték a zsidók az ellenállást Ezsdrás és Nehémiás idejében?

DS1994 Memory/Time iButton
Technical Documents Application Notes DS1994 Memory/Time iButton
APPLICATION NOTE 60
Abstract: This application note gives details on techniques for accurate time measurement with the Dallas Semiconductor DS1994 Memory/Time iButton. Significant improvement of timekeeping accuracy can be achieved by using a real-time clock (RTC) with supplemental nonvolatile SRAM for the storage of calibration constants. Whenever the timekeeper is reset, improved calibration constants can be stored in the nonvolatile SRAM, so that successive resets adaptively enhance accuracy. When the timekeeper is read, these constants are supplied along with the uncorrected time-base to a microprocessor program that calculates and displays a more accurate reading. In this way the practical effect of errors from temperature, initial calibration, quartz aging, and shock history can be minimized.
Techniques for Accurate Time Measurement with the Dallas Semiconductor DS1994 Memory/Time iButton
I. Historical Background
The first requirement for accuracy in time measurement arose from the need to determine longitude at sea from celestial measurements. Because of the earth's rotation, a time measurement error of 4 seconds creates a longitude error of 1 arc minute, or about 1 mile at latitudes near 30 degrees. To determine a ship's position to within a mile, it was essential to have a good sextant and a chronometer capable of giving the correct time to within 4 seconds, even after many days at sea.
The first navigational chronometers to provide the needed accuracy were precision mechanical devices. These instruments did not provide an accurate time reading directly. Instead, a chronometer was carefully characterized on land to determine exactly how fast or slow it was and how the error depended on temperature and other environmental factors. Each chronometer was supplied with its own unique set of characterization data which could be used at sea to calculate the correct time from the uncorrected time supplied by the instrument.
A modern, cheap quartz digital wristwatch is now superior to the best early navigational chronometers. With careful characterization and corrective calculation, it is possible to obtain a high degree of accuracy from a modern quartz timepiece. For practical reasons, the correction calculations that were so important for early chronometry are seldom performed with modern timepieces. As a result, a wristwatch, PC clock, or other quartz timepiece may gain or lose a second or more per day in its uncorrected reading. A properly executed corrective calculation can reduce this error substantially. Microprocessors and microcontrollers can now perform this calculation with relative ease, allowing a microprocessorcontrolled timekeeping device to achieve a dramatic increase in accuracy.
II. Sources of Timekeeping Error
The sources of error in a quartz crystal controlled timepiece are listed below:
A. Temperature Dependence
The oscillation frequency of a quartz oscillator depends on temperature. A typical 32.768kHz wristwatch crystal has a frequency which depends quadratically on temperature, with the maximum frequency occurring near "room" temperature (25°C).
B. Calibration Error
The oscillation frequency of a quartz oscillator depends to a degree on the values of the circuit components that comprise the oscillation circuit. Calibration error is the error in adjusting (trimming) the circuit components at the factory which causes the maximum frequency described in II.A above to be greater or less than the intended value.
C. Relaxation with Time
The manufacturing process induces mechanical stresses in the quartz crystal which affect its oscillation frequency. These stresses spontaneously relax during the lifetime of the crystal, resulting in a slow, longterm change in frequency.
D. Shock History
A severe mechanical shock can suddenly relax existing stresses in the quartz crystal or induce new stresses. This results in a step function change in the crystal frequency, followed by subsequent relaxation of the new stress pattern over time.
Changes in oscillation frequency caused by relaxation with time and shock history are not predictable and therefore not subject to automated correction. However, a recalibration performed after the change in frequency has occurred can eliminate these effects until they occur again. The two most important effects on practical timekeeping accuracy are therefore the temperature dependence of the oscillation frequency and the factory calibration error.
Temperature effects may vary widely in significance depending on the environment. A wristwatch worn continuously is exposed to a temperature environment which is very nearly constant. In this case, the observed error is due almost entirely to calibration error. Even if a watch is left on the dresser at night, it still experiences a daily average temperature environment which is very nearly constant from one day to the next. On the other hand, a timekeeper exposed to daily and seasonal extremes of outdoor temperature would be expected to exhibit substantially larger temperature effects.
In principle, the calibration error can be made arbitrarily small. However, in a manufacturing environment, it is impractical to calibrate very precisely for several reasons. Watches have mechanical adjustments for trimming the oscillator which have backlash and creep that limit the precision with which they can be set. A more important factor is that very exact calibration requires a long period of time to perform because the timekeeper requires time to accumulate a measurable error. As a result, watches and crystal controlled timekeepers used indoors are limited almost exclusively by the imprecision of their calibration.
III. Correction of Timekeeping Error
As noted above, the principal limitation on the accuracy of an indoor, crystal-controlled timekeeper is the precision of its factory calibration. Like the early navigational chronometer, the device is capable of measuring time very accurately but does not display the accurate time directly. To achieve the desired accuracy, it is necessary to determine the correction coefficients and then to perform a corrective calculation to determine the corrected time. This correction takes the following form:
Corrected Time = Uncorrected Time + (Uncorrected Time - A) / B
In the above equation, the values A and B are the correction coefficients that are obtained by characterization. To set the timekeeper and determine the values of A and B, the following steps are required:
At an initial time T1, synchronize the timekeeper with a highly accurate time standard. The National Institute of Standards and Technology (NIST) provides both a radio service (WWV at 5 MHz, 10 MHz, and 15 MHz) and a 9600 bps modem line (303-494-4774) for this purpose. Set the coefficient A equal to the time T1.
Wait a long period of time to allow the error in the uncorrected time to build up. Good results can be obtained with a delay of several days to a week, but the longer the delay time, the better. During the long delay time, the timekeeper should be exposed to the average temperature environment in which it will later be used.
At a later time T2 provided by the highly accurate time standard, read the uncorrected time T from the timekeeper and solve the following equation for the coefficient B.
B = (T - T1) / (T2 - T)
Now that the coefficients A and B have been determined, the corrected time can be computed from any uncorrected time measurement by applying the correction equation using the values of A and B obtained from the characterization. Note that the value of B may be positive or negative, depending on whether the timekeeper runs slow or fast respectively. It should also be noted that the value of B can be regarded as a large whole number (signed integer).
The correction described above, while simple in principle, is complicated by the fact that the practical units of time (years, months, days, hours, minutes, seconds) are related in a complicated way. To determine T - T1, for example, it is necessary to find the total number of seconds between the date and time represented by T1 and the date and time represented by T. To facilitate the corrective calculation, it is highly desirable that the timekeeper measure time in a single standard unit (e.g., seconds). One such standard is that of the UNIX operating system, in which time is kept as the total number of seconds that have elapsed since the beginning of January 1, 1970. Using this standard, the corrective calculations are easily performed with long integer arithmetic.
IV. Memory/Time iButton
The DS1994 Memory/Time iButton manufactured by Dallas Semiconductor is a small, sealed, internally powered timekeeping unit with 512 bytes of nonvolatile RAM memory and numerous specialized timekeeping features. Data transfer to and from the DS1994 is accomplished over a single serial data wire using the Dallas Semiconductor 1-Wire® protocols for data communication. The DS1994 has several characteristics which make it especially suitable for the type of corrective calculation described above:
The DS1994 accumulates date/time information in a 5-byte register as the number of 256ths of a second since some arbitrary reference date. (For compatibility with the UNIX operating system, use of the reference date January 1, 1970 is recommended.) This date/time format is ideal for performing the corrective calculation described above and also makes it easy to determine the day of the week. After the correction has been applied, the corrected date and time can be converted easily to the more standard form (MM/DD/YYYY, HH:MM:SS).
The correction coefficients A and B can be stored in the nonvolatile RAM memory of the DS1994. This modularity provides a manufacturing advantage because the DS1994 can be characterized and loaded with its A and B coefficients and then used later as a component for assembling the final timekeeping product. It is not necessary to tie up the entire product for the relatively long times needed to perform an accurate characterization of the DS1994. This modularity also facilitates repair or replacement.
The oscillation frequency of the DS1994 is fixed at the factory. The fixed-frequency circuit offers long-term stability that is superior to that of mechanically trimmed components because it is free of mechanical relaxation effects in the trim adjustment.
Because of the 1-Wire interface, the DS1994 may easily be located at some distance from the rest of the product. This is significant when the product itself generates heat that may affect the accuracy of the timekeeper. (For applications requiring extreme accuracy, in which the timekeeper itself is kept in a constant temperature oven, the packaging and 1-Wire interface of the DS1994 simplify product design.)
V. Programs to Calculate Corrected Time
Dallas Semiconductor has developed a demonstration program for the DS5000 (Intel 8051 compatible micro-controller) which calculates the corrected time from a characterized DS1994 and displays the results on an LCD display. Using this program and a properly characterized DS1994 with A and B coefficients stored in its nonvolatile memory, accuracies of 1 second in six months have been observed indoors over a two-month period. PC programs to characterize DS1994s and compute and store the correction coefficients have also been developed. The PC programs communicate with the DS1994s using the DS9097 COM Port Adapter and DS9092 iButton Probe. The adapter and probe attach to any RS232C serial port of the PC, and the PC reads and writes data to the DS1994 simply by touching it with the probe. The programs in this demonstration set are described below.
A. SetTime
This is a PC program which performs the calibration step described in section III.1. T1 is obtained from the DOS clock of the PC. Since PCs typically have poor timekeeping accuracy, it is necessary first to synchronize the PC clock with the NIST standard so that it can be used as a secondary time standard. (This synchronization can be performed with a 9600 or faster bps telephone modem and the MS DOS utility program TIMESET, available from Life Sciences Software, P.O. Box 587, Stanwood, Washington 98292, phone 360-387-9788. A similar program, WTIME, is available as a free utility for Microsoft Windows from PC Magazine, October 27, 1992.) To set the DS1994 time and the first correction coefficient A, type
SETTIME <com port number> <time zone offset>
at the DOS prompt and then touch the DS1994 with the probe. <com port number> is the number of the COM port to which the DS9097 adapter is attached. <time zone offset> is the number of hours of offset required, and is entered as -1 if the PC is set to daylight savings time. The program sets the time register and the A coefficient in the DS1994, responds with "Date and Time Successfully Set" and terminates.
B. CalTime
This is a PC program which performs the calibration step described in section III.3. Before using the program CalTime, the DS1994s should be allowed to remain for several days or weeks in the typical environment in which they will be used. T2 is obtained from the DOS clock of the PC. Again, it is necessary first to synchronize the PC clock with the NIST standard so that it can be used as a secondary standard. To compute and set the second correction coefficient B, type
CALTIME <com port number> <time zone offset>
at the DOS prompt and then touch the DS1994 with the probe. The program sets the B coefficient in the DS1994, responds with "Date and Time Successfully Calibrated" and terminates.
C. LCDTime
This is a program for the DS5000 microcontroller which reads the time and correction coefficients from a DS1994, computes the correction, and displays the corrected time, date, day of the week, and daylight/standard time indicator on an attached LCD display. (To avoid the problem of daylight savings time, the program reads standard time from the DS1994 and automatically converts it to daylight time when daylight time is in effect.) The program is written in KSC Pascal, and the Hitachi LCD controller is attached to the DS5000 in the manner recommended by KSC, with the base address changed from 6000 hex to 0000 hex. The program can be compiled with the SYSTEM51 (Ver 3.10) software development system from KSC Software Systems, Ludvig Holsteins Alle 137, DK-2750 Ballerup, Denmark, Phone (Int. 45) 44 97 69 11, Fax (Int. 45) 44 97 96 12.
D. ReadTime
This is a PC program which reads a DS1994 using the serial port adapter and displays corrected and uncorrected time values, calibration constants, and measurement errors. To read the DS1994 and display these results, type
READTIME <com port number> <time zone offset>
at the DOS prompt and then touch the DS1994 with the probe. The program displays the uncorrected date and time, the corrected date and time, the difference in seconds between the corrected and uncorrected times, the values of the correction coefficients A and B, the current DOS time, and the difference in seconds between the corrected time and the current DOS time.
Note that in all of the above programs, the values of A and B are stored in the unused Real Time Alarm and Interval Time Alarm registers in the "clock page" of the DS1994. This was done so that the 512 bytes of nonvolatile RAM memory could be kept free for other possible uses. The values of A and B can be independently reset at any time in the future with the SetTime and CalTime programs respectively.
VI. Tests of the Calibration Process
To investigate the effectiveness of the calibration process, a set of 50 DS1994s was divided into five groups of 10 parts each. The first calibration point was set with SetTime for all parts at 11:50 a.m. Central Standard Time on July 14, 1992. Each of the five groups, designated A, B, C, D, and E, were recalibrated after different periods of time. The second calibration point was set with CalTime for the various groups as follows:
Group A at 11:50 a.m. CST on July 16, 1992. Group B at 9:30 a.m. CST on July 22, 1992. Group C at 3:40 p.m. CST on July 29, 1992. Group D at 9:10 a.m. CST on August 3, 1992. Group E at 7:35 a.m. CST on August 13, 1992.
When the parts were not being read or calibrated, they remained in a desk drawer in an air-conditioned office environment. On September 15, 1992, at 11:50 a.m. CST, all parts were read with ReadTime and the errors in the corrected times were tabulated in seconds as shown in the table below:
Part # Group A Group B Group C Group D Group E
1 0.62 0.63 0.56 -0.29 0.05*
2 2.38 1.31 0.48 -0.09* 0.13*
3 3.03 0.74 0.20* -0.30 0.21
4 2.41 0.50 0.13* -0.07* -0.02*
5 2.79 0.81 0.79 0.01* -0.08*
6 1.02 0.43 0.21* 0.02* 0.08*
7 2.20 0.95 0.16* 0.04* 0.23
8 1.20 0.67 0.48 0.09* 0.04*
9 1.12 0.29* 0.07* 0.22* 0.19
10 1.79 1.3 0.76 0.07* -0.32
Mean 1.856 0.770 0.384 -0.030 0.051
Std.Dev. 0.827 0.355 0.265 0.164 0.165
Days Cal. 2.00 7.90 15.16 19.89 29.82
Days Idle 61.00 55.10 47.84 43.11 33.18
Days Cal. in the table above indicates the number of days between the first and second calibration points, and Days Idle represents the number of days after the second calibration point before the final reading was taken on September 15.
Note that the corrected times marked with asterisks represent errors of less than 2 seconds per year. The parts calibrated for shorter times show larger errors and larger standard deviations, indicating the effects of end-point calibration inaccuracy and short-term temperature fluctuations. (By comparison, the uncorrected times from the 50 DS1994s showed a mean error of 526 seconds/year, with a standard deviation of 210 seconds/year.)
A final measurement was made on July 14, 1993 at 11:50 a.m., one year after the initial setting. The uncorrected times showed a mean error of 550.6 seconds with a standard deviation of 207.8 seconds, consistent with the two-month measurement cited above. In parts per million (ppm), this is 17.5 ppm ± 6.6 ppm. The mean errors in the corrected times for the five groups were as follows:
Group A: 26.83 sec ± 6.81 sec (0.85 ppm ± 0.22 ppm)
Group B: 22.91 sec ± 6.94 sec (0.73 ppm ± 0.22 ppm)
Group C: 18.30 sec ± 3.83 sec (0.58 ppm ± 0.12 ppm)
Group D: 15.48 sec ± 2.81 sec (0.49 ppm ± 0.09 ppm)
Group E: 15.94 sec ± 3.70 sec (0.51 ppm ± 0.12 ppm)
While not as accurate as the measurements made over the two-month period, these accuracies are still impressive. The deviations in the corrected readings are all in the same direction, indicating a possible seasonal change in the temperature of the environment in which the parts were stored. As expected, the group having the shortest calibration period (Group A) had the greatest error. The average error in the corrected readings of groups D and E is 35 times smaller than the average error in the uncorrected readings.
VII. Summary
Significant improvement of timekeeping accuracy can be achieved by using a real time clock with supplemental nonvolatile SRAM for the storage of calibration constants. Whenever the timekeeper is reset, improved calibration constants can be stored in the nonvolatile SRAM, so that successive resets adaptively enhance accuracy. When the timekeeper is read, these constants are supplied along with the uncorrected time-base to a microprocessor program that calculates and displays a more accurate reading. If the timekeeper maintains time by counting the seconds from a designated reference time then a simple program code can quickly compute a more accurate, compensated time. In this way the practical effect of errors from temperature, initial calibration, quartz aging, and shock history can be minimized. Experimental data indicate that an accuracy of ± 2 seconds per year is achievable over a two-month period, and approximately 16 seconds over a full year.

\section{Introduction}
1+1 dimensional (``lineal") quantum gravity
is one of the areas of low-dimensional quantum field theory
which has attracted
more attention in recent years.
The role played by symmetries in these theories is obviously very
important, and here we shall be concerned
with the role of symmetries in the
quantization of the 1+1-dimensional matter-gravity field theory
with action\cite{pol81}
\begin{eqnarray}
{\cal I}(X,g) = {1 \over 2} \int d^2\xi ~ \sqrt{-g} ~
g^{\mu \nu} ~ \partial_\mu X_A \, \partial_\nu X^A ~,
\label{sxg}
\end{eqnarray}
where $g_{\mu \nu}$ is a metric tensor
with signature (1,-1), $A \! = \! 1,2,...,d$,
and $X$ is a d-component massless scalar field.

\noindent
In the quantization of this theory
one necessarily encounters anomalies that break part of
the symmetry of the classical theory, which, as seen from ${\cal I}(X,g)$,
has Weyl and diffeomorphism invariance\cite{pol81,pol87}.

In the conventional quantization
approach[1-4]
diffeomorphism invariance is preserved,
while  renouncing Weyl invariance.
Integrating out the
matter degrees of freedom using a
measure\cite{pol81,pol87} with the appropriate symmetries one obtains
an effective pure gravity theory
with action\footnote{Note that, for simplicity,
we set the cosmological constant to zero.}
\begin{eqnarray}
\Gamma^D(g) \! = {d \over 96 \pi} \!
\int \! d^2\xi_1 \, d^2\xi_2 \, \sqrt{-g(\xi_1)} \,
R(g(\xi_1)) ~ \Box^{-1}(\xi_1,\xi_2) ~ \sqrt{-g(\xi_2)} \, R(g(\xi_2))
\, , \label{sgp}
\end{eqnarray}
where $\Box^{-1}$ is the inverse of the Laplace-Beltrami operator.

Since $\Gamma^D(g)$ is diffeomorphism-invariant but
is not Weyl-invariant, the energy-momentum
tensor $T^D_{\mu \nu}  \! \equiv \! (2 / \sqrt{-g})
(\delta \Gamma^D(g) / \delta g^{\mu \nu})$
is covariantly conserved, but possesses non-vanishing trace
\begin{eqnarray}
\nabla_\mu (g^{\mu \nu} T^D_{\nu \alpha}) = 0  ~,
{}~~~~~g^{\mu \nu} T^D_{\mu \nu} = {d \over 24 \pi} R(g) ~.
\label{anop}
\end{eqnarray}

Recently, an alternative approach to the quantization of the classical
theory (\ref{sxg}) has been
considered[5-7],
in which the functional measure for the integration over the matter fields
is Weyl-invariant and invariant under area-preserving diffeomorphisms
({\it i.e.} diffeomorphisms of unit Jacobian),
but is not invariant under non-area-preserving diffeomorphisms.
This leads to the following
effective action\footnote{Note that, by appropriate choice
of measure, one can obtain more general
effective actions that are invariant
when $g_{\mu \nu}$ is transformed as
$\delta g_{\mu \nu} \! = \!
\xi^\alpha \partial_\alpha g_{\mu \nu}
+ g_{\alpha \nu} \partial_\mu \xi^\alpha
+ g_{\alpha \mu} \partial_\nu \xi^\alpha
+ a g_{\mu \nu} \partial_\alpha \xi^\alpha$,
where $a$ is a fixed real parameter.
It is seen that this combination of diffeomorphisms and
Weyl transformations
is equivalent to the
statement that $g_{\mu \nu}$ is a tensor density of
weight $a$.
Such a modification of the standard formula ($a \! = \!0$) leaves the
classical action invariant because
the combination $\sqrt{-g} g^{\mu \nu}$
is insensitive to the weight of $g^{\mu \nu}$.
The Weyl-invariant approach considered in the present paper
corresponds to the limit $a \! \rightarrow \! \infty$ with the
prescription that
$\partial_\mu \xi^\mu \! \rightarrow \! w/a$
for $a \! \rightarrow \! \infty$, where $w$
is an arbitrary function.}
\begin{eqnarray}
\Gamma^W(\gamma) \! = \! {d \over 96 \pi}
\int d^2\xi_1 \, d^2\xi_2 ~  \, R(\gamma(\xi_1)) \,
\Box^{-1}(\xi_1,\xi_2) \,  R(\gamma(\xi_2)) ~,
\label{sgj}
\end{eqnarray}
where $\gamma^{\mu \nu} \equiv \sqrt{- g} \, g^{\mu \nu}$.
The fact that $\Gamma^W(\gamma)$
is Weyl-invariant but is not invariant under general diffeomorphisms
leads to the anomaly relations
\begin{eqnarray}
\hat\nabla_\mu (\gamma^{\mu \nu} T^W_{\nu \alpha}) \!&=&\!
- {d \over 48 \pi} \partial_\alpha R(\gamma) ~,\label{anojgammad}\\
\gamma^{\mu \nu} T^W_{\mu \nu} \!&=&\! 0 ~,
\label{anojgammaw}
\end{eqnarray}
where $\hat\nabla$ is the
covariant derivative computed with the metric $\gamma_{\mu\nu}$, and
\begin{eqnarray}
T^W_{\mu \nu} ~ \equiv ~ {2 \over \sqrt{-g}}
{\delta \Gamma^W(\gamma) \over \delta g^{\mu \nu}}
{}~ = ~ 2 {\delta \Gamma^W(\gamma) \over \delta \gamma^{\mu \nu}} -
\gamma_{\mu \nu} \gamma^{\alpha \beta}
{\delta \Gamma^W(\gamma) \over \delta \gamma^{\alpha \beta}} ~,
\label{tj}
\end{eqnarray}
while the invariance of $\Gamma^W(\gamma)$ under area-preserving
diffeomorphisms is encoded in the relation
\begin{eqnarray}
\hat\nabla_\mu \hat\nabla_\nu (\gamma^{\beta \nu} \epsilon^{\mu \alpha}
T^W_{\alpha \beta}) = 0~,
\label{tjack}
\end{eqnarray}
which is consistent with (\ref{anojgammad}).

In the following we shall
derive the anomalous
Ward identities both for the
Weyl-invariant approach and
the conventional diffeomorphism invariant approach,
and observe that, although the difference in the symmetries
leads to several differences at intermediate steps of the
derivation, the final results are equivalent.

\section{Anomalous Ward Identities}
We start by considering the functional integrals
\begin{eqnarray}
Z^D[J] \!\!&=&\!\! \int {{\cal D} g \over \Omega_{diff}} ~
{\rm exp} (i \Gamma^D (g) + i \int \sqrt{-g} g^{\mu \nu} J^D_{\mu \nu}) ~,
\label{func}\\
Z^W[J] \!\!&=&\!\! \int {{\cal D} \gamma \over \Omega_{Sdiff}} ~
{\rm exp}(i \Gamma^W (\gamma)+ i \int \gamma^{\mu \nu} J^W_{\mu \nu}) ~,
\label{functional}
\end{eqnarray}
where $J^D_{\mu \nu}$ and $J^W_{\mu \nu}$ are sources,
$\Omega_{diff}$ is the volume of the diffeomorphism group,
and $\Omega_{Sdiff}$ is  the volume of the group of the area-preserving
diffeomorphisms. The volume of the Weyl
group does not appear in (\ref{functional}) because the functional
integral is already
written in terms of the Weyl-invariant field $\gamma$.

\noindent
$Z^D[J]$ and $Z^W[J]$ are the generating functionals for the
Green's functions of the diffeomorphism-invariant approach
and the Weyl-invariant approach
respectively.

In order to factorize out the gauge volume one can
fix the gauge
and introduce the corresponding action
for the ghost fields.
We choose
to work in the light-cone gauge, and,
after integrating out the ghost fields, $Z^{D}$ and $Z^{W}$ take
the following form
\begin{eqnarray}
\label{funct}
Z^D[J] \!\!&=&\!\! \int  {\cal D} g_{++} ~ {\rm exp}
\left (i \Gamma^D(g) + i \Gamma^D_{gh}(g) +
i \int g^{++} J^D_{++} \right ) ~, \label{functeff}\\
Z^W[J] \!\!&=&\!\! \int {\cal D} \gamma_{++} ~
{\rm exp} \left (i \Gamma^W({\gamma}) + i \Gamma^W_{gh}({\gamma})
+ i \int \gamma^{++} J^W_{++} \right )
{}~, \label{functional3}
\end{eqnarray}
where $\Gamma^{D} \! + \! \Gamma^{D}_{gh}$
and $\Gamma^{W} \! + \! \Gamma^{W}_{gh}$
are gauge-fixed actions for gravity.

\noindent
Our choice of gauge is motivated by the fact
that[5-7]
in the light-cone gauge $\Gamma^W \! + \! \Gamma^{W}_{gh}$
takes the same form of $\Gamma^D \! + \! \Gamma^{D}_{gh}$,
and we intend to exploit this correspondence
in the investigation of the anomalous Ward identities.
Still, in the analysis we shall need to take into account
the fact that the measure ${\cal D}\gamma$, which is Weyl-invariant
but not diffeomorphism-invariant, is different from
the diffeomorphism-invariant but not Weyl-invariant
measure ${\cal D}g$. Moreover, since
$\gamma$ and $g$ have different
transformation properties,
$\Gamma^W \! + \! \Gamma^{W}_{gh}$ and $\Gamma^D \! + \! \Gamma^{D}_{gh}$
satisfy different anomaly relations;
specifically\cite{abs1}
\begin{eqnarray}
\nabla_\mu (g^{\mu \nu} \Theta^D_{\nu \alpha}) = 0  ~,
{}~~~~~g^{\mu \nu} \Theta^D_{\mu \nu} = {d-28 \over 24 \pi} R(g) ~,
\label{anopgh}\\
\hat\nabla_\mu (\gamma^{\mu \nu} \Theta^W_{\nu \alpha}) =
- {d-28 \over 48 \pi} \partial_\alpha R(\gamma) ~,
{}~~~~~\gamma^{\mu \nu} \Theta^W_{\mu \nu} = 0 ~,
\label{anojgh}
\end{eqnarray}
where
\begin{eqnarray}
\Theta^{D,W}_{\mu \nu}  \equiv {2 \over \sqrt{-g}}
{\delta (\Gamma^{D,W} + \Gamma^{D,W}_{gh}) \over \delta g^{\mu \nu}} ~.
\label{tpgh}
\end{eqnarray}

We now consider
the following infinitesimal shifts in the functional variables
of integration
\begin{eqnarray}
\delta_f g_{++}=(2 \partial_+ -g_{++}\partial_-) \, \delta f +
\delta f \, \partial_- g_{++} ~,
\label{variation}\\
\delta_f \gamma_{++}=(2 \partial_+ -\gamma_{++}\partial_-) \, \delta f +
\delta f \, \partial_- \gamma_{++} ~,
\label{variationj}
\end{eqnarray}
and observe that
\begin{eqnarray}
\! \int \!
\frac{\delta [\Gamma^D(g) \! + \! \Gamma^D_{gh}(g)]}{\delta g_{++}}
\delta_f g_{++} \! = \!
\!\int \!
[ \nabla_\mu (g^{\mu \nu} \Theta^D_{\nu -})
\! - \! \frac{1}{2}\nabla_- (g^{\mu \nu} \Theta^D_{\mu \nu}) ]
\delta f
\! = \!\! \int \!
\frac{28 \! - \! d}{48 \pi}  \partial^3_- g_{++}  \delta f
\label{eqgac426}\\
\! \int \!
\frac{\delta [\Gamma^W(\gamma) \!
+ \! \Gamma^W_{gh}(\gamma)]}{\delta \gamma_{++}}
\delta_f \gamma_{++} \! = \!
\! = \!\! \int \!
[ \nabla_\mu (g^{\mu \nu} \Theta^W_{\nu -})
\! - \! \frac{1}{2}\nabla_- (g^{\mu \nu} \Theta^W_{\mu \nu}) ]
\delta f \! = \!\! \int \!
\frac{28 \! - \! d}{48 \pi} \partial^3_- \gamma_{++}  \delta f ,
\label{eqgac426bis}
\end{eqnarray}
where we used the anomaly relations (\ref{anopgh}) and (\ref{anojgh}).

Following a standard procedure\cite{bil95},
the relations (\ref{eqgac426}) and (\ref{eqgac426bis})
lead to the following
anomalous Ward identities
\begin{eqnarray}
\sum^n_i  \! \left < g_{++} \!  (\xi_1 ) \!
\dots \! \delta_{\!f} \! g_{++} \! (\xi_i ) \!
\dots  \! g_{++} \! (\xi_n)  \right > \!
+ \! \frac{d  \! \! - \! \!  28  \! \! +  \! \! \lambda^D}{i 48 \pi}
 \! \! \int \!  \! d\xi^2  \! \, \delta \! f \! ( \! \xi \! )
\left<  \partial_-^3 g_{++} \! (  \xi  )
g_{++} \! (\xi_1 ) \! \dots  \! g_{++} \!
(\xi_n)  \right > \!  \! = \!  \! 0.
\label{Ward}\\
\sum^n_i  \! \left < \gamma_{++} \!  (\xi_1 ) \!
\dots \! \delta_{\!f} \! \gamma_{++} \! (\xi_i ) \!
\dots  \! \gamma_{++} \! (\xi_n)  \right > \!
+ \! \frac{d  \! \! - \! \!  28  \! \! +  \! \! \lambda^W}{i 48 \pi}
 \! \! \int \!  \! d\xi^2  \! \, \delta \! f \! ( \! \xi \! )
\left<  \partial_-^3 \gamma_{++} \! (  \xi  )
\gamma_{++} \! (\xi_1 ) \! \dots  \! \gamma_{++} \!
(\xi_n)  \right > \!  \! = \!  \! 0.
\label{Wardj}
\end{eqnarray}
Here $\lambda^D$ is the additional contribution to the anomaly
which is due to the fact that $\delta_f g_{++}$
is a composition of a diffeomorphism
and a Weyl transformation on $g_{++}$,
and therefore the diffeomorphism-invariant
but not Weyl-invariant measure ${\cal D}g_{++}$ is not invariant
under $g_{++} \rightarrow g_{++} + \delta_f g_{++}$.
Analogously, the presence of $\lambda^W$ is due to the fact that
$\delta_f \gamma_{++}$ is an infinitesimal
(not area-preserving) diffeomorphism
transformation on $\gamma_{++}$,
and therefore the measure ${\cal D}\gamma_{++}$ is not invariant
under $\gamma_{++} \rightarrow \gamma_{++} + \delta_f \gamma_{++}$.
The values of $\lambda^{D}$ and $\lambda^{W}$ can
be fixed by requiring that
the theory be independent of the choice of gauge.
In Ref.\cite{pol87}
the class of gauges
$g_{--} \! = \!g_{--}^B$, $g_{+-} \! = \! 1$ is considered, and
it is found that the independence of the partition function on
the choice of $g_{--}^B$ requires that
\begin{equation}
\label{lambda}
d-28+\lambda^D = {d-13- \sqrt{(d -1)(d - 25)} \over 2}~.
\end{equation}
Following the corresponding procedure for the Weyl invariant approach
one finds that also $\lambda^W$ must satisfy Eq.(\ref{lambda}),
{\it i.e.} $\lambda^W \! = \! \lambda^D$.
This observation together with the results (\ref{Ward}) and (\ref{Wardj})
indicates that the anomalous Ward identities satisfied by $\gamma_{++}$
in the Weyl-invariant approach are identical to the ones
satisfied by $g_{++}$
in the diffeomorphism-invariant approach.
Since these Ward identities completely
determine\cite{pol87}
the Green's functions, also the Green's functions
are identical.

\section{Conclusion}
The investigation of the anomalous Ward identities
indicates that the two approaches are equivalent,
and this is consistent with the results\cite{abs1} of the (classical)
Dirac Hamiltonian analysis.
It appears that the physics described by the model is independent
of the local term\cite{jac95} that one needs to add to the action
in order to convert the Weyl anomaly into a diffeomorphism anomaly.
This does not always happen in anomalous quantum field theories,
for example in the chiral Schwinger model\cite{jac85}
the mass emergent
at the quantum level as a result of the anomaly
does depend on the coefficient of one such local term.

It is also interesting to notice that
in deriving the equivalence of the two approaches at the level of
the anomalous Ward identities
a key role is played by the $-$ component of the combination
$\nabla_\mu (g^{\mu \nu} \Theta_{\nu \alpha})
-\nabla_\alpha (g^{\mu \nu} \Theta_{\mu \nu})/2$
[see Eqs.(\ref{eqgac426}) and (\ref{eqgac426bis})],
which (in the chosen gauges) takes the same form in both approaches.
Clearly this combination of the anomaly relations
encodes some essential feature of the model,
but its physical interpretation is not yet clear to us.

Finally, we want to point out that
1+1-dimensional quantum gravities of the type here consedered
and their supersymmetric extensions are related\cite{pol87,dis88,stat}
to some low-dimensional models in statistical physics,
such as the Ising model, random surfaces, percolation, tree-like polymers,
and self-avoiding polymers.
In several occasions
results first obtained in the study of the quantum field theories have
been useful also in the context of the statistical models and
{\it vice versa}.
Since only recently there has been increased interest in the Weyl invariant
approach, the possibility of
application of this new viewpoint to the study of statistical
models has not yet been investigated.

Public TV's "Julia Child of the Horticulture" 1966-69.
October. Days shorten. Get colder. Leaves fall. We spend more time indoors, less time with nature.
Here's a short list of plants that take neglect and still perform. Indeed they ask nothing more than regular watering and filtered sun or low light.
1. Oxalis is one of the easiest, most forgiving, fun-to-watch plants. Green (regnellii) or purple (triangularis) leaves. Leaves open at daylight (watch 33 second video link that shows leaves opening at 23 seconds) and close each night as darkness sets in. Wants light in order to produce flowers, but not full sun. Likes damp (not soggy) soil. When too dry, plant tells you; it looks like it's collapsing. But it comes right back after watering. Blooms for long periods indoors, with a rest period after blooming.
2. Spathiphyllum is also easy and forgiving. Many varieties, different size plants. Buy the small size. They grow just as well and are more manageable. If plants are getting dry, the leaves begin to sag–that's the signal to water. If they get too dry the tips turn brown; but the plant survives, and the tips can be trimmed if desired. I've found these plants impossible to kill. Low light is fine. they don't like bright light. Blooms year round.
Video short with instructions, basically tells you how easy this plant is to care for. I didn't know it's also an air purifier but, according to the video, it is.
3. Bromelliad blooms are vibrant, last months, and clearly add color to any room. They do need good light, usually bright indirect light, but require little care, definitely don't want to be overwatered.

'Game of Thrones' Featurette to Air Next Month
Will it give season five hints?
Game of Thrones fans will get a a behind-the-scenes look at the show on Feb. 8, when HBO airs a new featurette called "A Day In The Life." A rather quaint name for a show about killing, plotting and other nefarious deeds, no?
See more 'Game of Thrones' Reveals First Official Season 5 Snippets
The special airs at 7:30 p.m. ET/PT, and was first reported by the Game of Thrones fanatics over at Watchers on the Wall after a tipster spotted it on their HBO Go schedule.
Ahead of season four, HBO aired "Ice and Fire: A Foreshadowing," which gave viewers a look at the new characters for that season as well as a taste of the year's big storylines. It's unclear if that will be the case here, but there are plenty of new characters lined up for season five fans are surely dying to know about.

So far HBO has released a little footage from season five, and it has also been teasing the upcoming year with its Three-Eyed Raven viral site.
No premiere date has been set, but the show has historically bowed in late March or April.

Tuesday- December 7, 2010- late this evening, beginning at 11:35 central time, New Orleans' own good time trumpeter and Basin Street Records recording artist will be a special guest on Late Night with Jimmy Fallon. If previous guest appearances are any guide, Ruffins will sit in with the house band for the entire broadcast. Since the house band is the acclaimed hip hop group, the Roots, led by the amazing drummer ?uestlove, I suspect that they will have plenty of musical common ground to jam on.
Monday- December 6, 2010- this evening the patriarch of the New Orleans jazz family will take the altar at the church in Jackson Square for the latest installment of the Christmas New Orleans Style concert series. The performance starts at 6 PM and I expect tasteful renditions of some of the holiday standards.
Saturday- December 4, 2010- this evening one of the hottest saxophonists to emerge from the Crescent City in the past 15 years headlines at the French Quarter club on the corner of Esplanade Avenue and Decatur Street. Fletcher first made a name for himself playing with the trumpeter Terence Blanchard after his studies at the New Orleans Center for Creative Arts. He was a finalist in the Thelonious Monk Sax competition and has recorded with Anita Baker, Teena Marie, Stevie Wonder and Chaka Khan among others. Fletcher is currently a member of the New Orleans Jazz Orchestra led by Irvin Mayfield. Tonight his band features stalwarts of the local scene including Terrence Higgins on drums, Donald Ramsey on bass, Kendrick Marshall on keys and Jake Larson on guitar.
This past summer's no-cover concert series on Friday nights was such a success for the uptown club that they have decided to continue it on selected weekends throughout the regular year. Tonight's featured acts are Supagroup, Brah and the Happy Talk Band. Brah is the only band on the lineup I am not familiar with but considering their name, I suspect we will be in for some tongue-in-cheek music. Supagroup is New Orleans hard rock heroes who have been on hiatus having babies- so I suspect that the Lee brothers, who lead the band, will be looking forward to rocking the stage. The Happy Talk Band has been tearing it up lately. Alex McMurray channels his inner Jimmy Page turning the country-rock ditties of leader Luke Allen (pictured) into rave-ups.
Music from the HBO series "Tremé" is nominated in two categories – best compilation soundtrack, and best song written for motion picture or television, for "This City." The song, which was composed by roots musician and activist Steve Earle, closed out the first season of the HBO production.
Trumpeter and artistic director for Jazz at Lincoln Center Wynton Marsalis is nominated for best improvised jazz solo, for "Van Gogh," which appears on "Portrait in Seven Shades." Marsalis has won nine Grammys in the past.
Artists connected to New Orleans were also nominated. Bluesman Buddy Guy, who was born in Louisiana, is up against Dr. John in the best contemporary blues album category. D.L. Menard, The Pine Leaf Boys, Chubby Carrier and the Bayou Swamp Band, Feufollet and Cedric Watson et Bijou were nominated in the zydeco/Cajun category.
Wednesday- December 1, 2010- beginning this evening and continuing through the month of December the powerhouse vocalist will be performing at the uptown club. Jenn's voice can go from a whisper to a scream and she is as comfortable playing jazz standards as she is belting the blues. Tonight Dave Pomerleau of Johnny Sketch and the Dirty Notes joins her on bass along with other musicians who have yet to identify themselves. Suffice it to say, they will rock.
Tuesday- November 30, 2010- this evening you can catch the cream of the crop of local musicians who are busy bending genres while you are listening to the same ole thing. At 10 PM, WATIV Mashup appears at the Open Ears series upstairs at the Blue Nile. This band features Will Thompson IV on keyboards, Chris Alford on guitar, James Singleton on bass and Simon Lott on drums. They are expecting special guests including Rob Cambre on guitar, David Polk on saxophones, and Bruce Golden on percussion. I have no idea what they will be playing, but I promise it will be interesting. A little later, Crimes Against Jazz appear at the Circle Bar (pictured) at 11 PM. This band features Josh Wexler on keyboards and melodica, Jonathan Freilich on guitar, Jesse Morrow on bass and Justin Peake on assorted percussion, loops and other interesting stuff. Josh promises, "Post-pop, avant-punk, pre-camp, neo-minimalist, quasi-continental, thoroughly Freudian, secular humanist free improv for uptown residents with a downtown soul." Since when is the Circle Bar uptown?

The alarming graduation statistics in higher education institutions have resulted in an increased demand on finding ways to improve the learning environment for students to help them graduate in a successful and timely manner. With the rise of data available about past students, machine learning researchers have been able to learn predictive models that solve different problems in the education domain. In this paper, we focus on the problem of course recommendation that aims to recommend to each student a set of courses from which they can register for in their following term, for the ultimate goal of improving the student's GPA and graduation time. We first propose a different definition for the course recommendation problem statement, by focusing on recommending courses on which the students' expected grades will help maintain or improve their GPAs. We then leverage two widely-known representation learning techniques, in order to learn the sequence by which students take courses and create better personalized rankings for students. Our experiments on a large dataset obtained from the University of Minnesota that includes students from 23 different majors show that the methods based on the proposed problem statement can better recommend courses on which the students are expected to perform well and that align with their degree programs. Moreover, the results show that the proposed methods achieve statistically significant results for course recommendation over the current methods.

Wausau Early Birds Rotary Club, founded in 1993 (Club #29175), is part of Rotary International District 6220. One of The Wausau Early Birds Rotary Club's major purposes is to raise and distribute philanthropic funds for worthy community service projects in the Wausau area. These projects further Rotary's mission of community and vocational service and the goals of the Wausau Early Birds Rotary Club. In addition, the Wausau Early Birds Rotary Club will support international efforts to eradicate polio and to promote basic needs of the less fortunate in other countries.
Projects supported by parents for the benefit of their own children, such as youth activity teams, trips, camps, scholarships, etc.
Grants generally range from $100-$2,500. When and if additional monies are available, the Club will entertain requests for projects over $2,500. Grants will not fund 100% of the project cost. The Club Board of Directors will make the final decision on grant applications up to $2500.00, with majority member approval required above that level. The application may be accepted, denied, or tabled for more information. The amount granted may be less than the amount requested. Grants are limited to one per project in a twelve-month period, and for only two consecutive years for a project, except for continuing Rotary programs. A second consecutive year request will be funded at no more than half the first year funding. If a request is declined, an organization may reapply the following year.
Each grant must be acknowledged in writing promptly upon receipt of the grant funds. In addition, the grant recipient may be asked to attend a meeting of the Wausau Early Birds Rotary Club for presentation of the grant award. It is also requested that all grant recipients provide a letter indicating how grant funds were used within 60 days from the end of the funded project, and a grant recipient may be required to present a report on the progress and outcomes of their project to the Rotary Club membership. The Club may issue information to the media about its grant awards, and recipients should acknowledge the Wausau Early Birds Rotary Club in their publicity.
Grant requests may be considered by the Board on a monthly basis, but at least bi-annually. Award notification or regrets will be sent within 30 days of the Board decision.
