LIMIT THEOREMS FOR STANDARDIZED PARTIAL SUMS OF WEAKLY EXCHANGEABLE ARRAYS

A symmetric array of random variables is weakly exchangeable if, when the same arbitrary permutation is applied to rows and columns, the joint distribution remains the same. We consider the asymptotic distribution of the standardized sums of the elements of the upper left hand corner of the partitioned array, generalizing results on U-statistics. In general, the asymptotic distribution is normal, but if the array is first standardized by subtracting row and column means, then it is a linear form in a normal variable and independent squares of normal variables with coefficients depending on the limits of the eigenvalues of the array.     

METHOD OF ESTIMATION FOR SAMPLING FROM INCOMPLETE FRAMES

The planning of any sample survey or census requires the existence of a sampling frame comprising a list of all the sampling units. But unfortunately there is hardly a situation in practice where the frame is available in the form the sampler desires to use. Most commonly some units of the target population are not listed in the frame, and the frame may contain units which do not belong to the target population. In this investigation a suitable method of estimation is proposed when sampling is done from such imperfect frames and a geographical ordering of the units can be established.     

A first generation critic comes of age: Reflections of a critical gerontologist

This paper reflects upon the direction and evolution of my scholarly endeavors as a sociologist of four decades in the field of aging, with thoughts on the future direction of this work and the challenges for the larger field. The perspective presented is located within two frameworks of active debate: the sociology of knowledge(s) [Gouldner, A. 1970. The Coming Crisis of Western Sociology. New York: Basic Books] and public sociology, which is one of the four major types of sociology identified by Burawoy [Burawoy, M. (2005, 2007). A call for public sociology. In D. Clawson, R. Zussman, J. Misra, N. Gerstel, R. Stokes, & R. L. Anderton (Eds.), Public Sociology. Berkeley: University of California Press.], also including traditional professional sociology, policy sociology, and critical sociology.

A Different Look at the “Population Problem”

The elite in Iran have been trained in Western economic ideas and committed to solving the problem of poverty either by Marxist or by neo-liberal methods. The author found that neither fit the real situation of people who live in traditional ways. Indeed, economic thought and modern practice are the causes of poverty. They have also imposed on people the false idea that population growth, rather than policies of domination, are the source of environmental damage and shortages.     

Population Dynamics: Poverty,Inequality, and Self-Regulating Fertility Rates

Population growth without a parallel increase in capital impoverishes any society and tends to deepen inequality. The system is dynamic because people who perceive or foresee contracting economic opportunity usually restrict family size. Worsening poverty feeds back into the loop to slow, then stop further population growth.     

A population size estimate of the finless porpoise,Neophocaena phocaenoides, from aerial sighting surveys in Ariake Sound and Tachibana Bay, Japan

We estimated the population size of the finless porpoise (Neophocaena phocaenoides) in Ariake Sound and Tachibana Bay of western Kyushu, southwestern Japan, from aerial sighting surveys using line transect methods. All 12 surveys were conducted from May 1993 to May 1994 (8 in Ariake Sound and 4 in Tachibana Bay). In addition to these, 14 surveys were also carried out to obtain information on porpoise occurrence in Tachibana Bay (5 surveys) and in neighboring Sumo Nada (5) and Yatsushiro Sound (4). In Ariake Sound, 225 porpoise groups (369 animals) were detected during all flights totalling 1,694.4 km. In Tachibana Bay, a total of 997.8 km was surveyed and 55 groups (290 animals) were sighted. However, no sightings were recorded in Sumo Nada (distance searched = 148.7 km) and Yatsushiro Sound (208.4 km). In Ariake Sound, few sightings were recorded from waters shallower than 5 m in depth. In Tachibana Bay all animals were detected from waters of less than 50 m depth. The population size was estimated as 1,983 animals in Ariake Sound (95% CI = 1,382-2,847), 1,110 in Tachibana Bay (95% CI = 642-1,920), and 3,093 in the 2 waters (1.3 individuals/km², 95% CI = 2,278-4,201).     

Bayesian estimation of the difference between two proportions

This paper is concerned with the problem of allocating a fixed number of trials between two independent binomial populations with unknown success probabilities θ₁ and θ₂, in order to estimate θ₁ - θ₂ with squared error loss. Introducing independent beta priors on θ₁ and θ₂, a heuristic allocation procedure is introduced and compared both with the optimal and with the best fixed allocation procedure. Numerical and asymptotic results of these comparisons are given and seem to indicate that there are situations when the best fixed allocation procedure performs almost as well as the optimal procedure.
