Vertical Gravity Gradient

Careful gravity measurements with La Coste‐Romberg geodetic gravimeters were carried out in tall buildings on a floor‐to‐floor basis in New York City and on the Armstrong Tower, Alpine, New Jersey. Corrections for the instrumental drift and tidal gravity variation and for the Bouguer effect, topography, mass of the buildings, and subway and basement excavations have been applied to the gravity data, which are tied to the absolute gravity value of the National Gravity Base Station of Washington, D. C. The observed gravity versus elevation curves are nonlinear, particularly near the surface of the ground; the slope of the observed gravity anomaly versus elevation curves reverses sign at an elevation of about 170 ft for the campus buildings and about 350 ft for the downtown buildings, and is nearly linear without a reversal for the Armstrong Tower. The vertical gradients vary substantially even within short distances. Comparisons of the corrected observed gradients with the theoretical gradients of gravity are made. The anomalous gradient anomalies are positive and are correlated with the positive isostatic surface gravity anomalies. Calibration of gravimeters against the observed vertical gradient of gravity to an accuracy of ±2 μgal is definitely feasible provided the gradient is predetermined to a comparable accuracy by a standard instrument.

In their paper, Kuo et al, following the footsteps of Hammer (1938), reported interesting vertical gradient observations in high buildings with a gravity meter. However, conclusion (5) drawn by Kuo et al should be discussed briefly in order to avoid an incorrect impression.

State Board

On September 15, 1930, the State Board of Commerce and Navigation of New Jersey made a ruling that aircraft would not be permitted to land on any New Jersey waters above tidewater within the jurisdiction of the state. The application had been made for permission to operate a five passenger flying boat between Nolan's Point, Lake Hopatcong, a vacation resort, and New York City, and to set off a portion of the lake to make a landing place for the hydroairplane. It was stated that other inland waters in New Jersey were being used for a similar purpose, and the ground of the refusal was that aircraft flying from water constituted a menace to surface navigation. This ruling created considerable newspaper comment and aroused vigorous protest from persons interested in aviation, and by order of October 20, 1930, the ruling was limited to Lake Hopatcong.

Second Peak

The five boroughs of New York City (NYC) were early epicenters of the Covid-19 pandemic in the United States, with over 380,000 cases by May 31. High caseloads were also seen in nearby counties in New Jersey (NJ), Connecticut (CT) and New York (NY). The pandemic started in the area in March with an exponential rise in the number of daily cases, peaked in early April, briefly declined, and then, showed clear signs of a second peak in several counties. We will show that despite control measures such as lockdown and restriction of movement during the exponential rise in daily cases, there was a significant net migration of households from NYC boroughs to the neighboring counties in NJ, CT and NY State. We propose that the second peak in daily cases in these counties around NYC was due, in part, to the movement of people from NYC boroughs to these counties. We estimate the movement of people using "Change of Address" (CoA) data from the US Postal Service, provided under the "Freedom of Information Act" of 1967. To identify the timing of the second peak and the number of cases in it, we use a previously proposed SIR model, which accurately describes the early stages of the coronavirus pandemic in European countries. Subtracting the model fits from the data identified, we establish the timing and the number of cases, NCS, in the second peak. We then related the number of cases in the second peak to the county population density, P, and the excess Change of Address, ECoA, into each county using the simple model N_CS~P^α E_CoA^β which fits the data very well with α = 0.68, β = 0.31 (R^2 = 0.74, p = 1.3e-8). We also find that the time between the first and second peaks was proportional to the distance of the county seat from NY Penn Station, suggesting that this migration of households and disease was a directed flow and not a diffusion process. Our analysis provides a simple method to use change of address data to track the spread of an infectious agent, such as SARS-Cov-2, due to migrations away from epicenters during the initial stages of a pandemic.

Jazz Musician

This chapter analyses Eternal Sunshine of the Spotless Mind (2004) and Be Kind Rewind (2008). In the former, Joel has his memory of his ex-lover Clementine erased before deciding to try to reverse the process by hiding her in memories where she does not belong. In the latter, two bumbling video-store clerks in Passaic, New Jersey produce “sweded” versions of popular films after the VHS tapes of these films are accidentally erased. When the clerks are forced to stop their productions due to copyright infringement, they decide instead to enlist the whole town in the making of a film about the legendary jazz musician Fats Waller (1904–43), who in the film is erroneously believed to have been from Passaic, when in reality Waller was born in New York City. Author Yu-Yun Hsieh compares the exploration of personal memory in Eternal Sunshine with the production of collective memory in Be Kind, noting that in both cases “fictional” or “inauthentic” memories are created to preserve a relationship, whether between Joel and Clementine in the former or between the inhabitants of Passaic in the latter. In both films, memories are open to revision but preserve an essence of truth.

The Mean

This study examined median household income (MHI) of communities with community emergency response teams (CERTs). Preliminary data from New York City showed that in three of five counties, the mean MHI in CERT communities exceeded countywide MHI by up to $19,000. The research was then expanded to New Jersey, where, of 18 counties with CERTs, the mean MHI exceeded the countywide MHI in 15 counties (83 percent of the time). In counties where the mean CERT-community MHI was higher, it exceeded the county MHI by $6,060. Mean CERT-community MHI also exceeded the state’s MHI by over $5,000 ($60,745 versus $55,146). Given recent examples of the vulnerability of poor and working-class communities, emergency management agencies at all levels need to target CERT resources based on need, not on demand.
