Politics and ideology in migration policy formulation: the case of Kuwait

In 1716, 3 prominent families of the original Kuwaitis agreed that 1 family would control finance and commerce, another seafaring activities, and the 3rd the government. This continued allegiance has been instrumental in shaping migration policy in Kuwait. Migration to Kuwait began in the 1930s-1940s to meet labor needs of the oil industry and the social infrastructure. This began a steady increase, with several setbacks in the early 1970s, of the migrant population. Between (1959-1964), Kuwait had to determine how it would exist and operate as an independent state. The new state established migration policy based on a need for national identity and on weighing the interests of 4 political groups: the ruling family; the wealthy merchants; the Arab Nationalist Movement; and Kuwaiti Nationalists. 3 migration laws emerged which satisfied the 4 groups and in some form continued into the 1980s. These laws basically allowed the continuation of free immigration of labor with the government controlling entry, movement, rights, and employment of the migrants while stressing neutrality and reciprocity with other states, especially Arab states. 1 law greatly limited the number of citizenships to nonKuwaitis and guaranteed economic control and major share of profits to Kuwaitis. Between 1965-1984, many changes to migration policy occurred for political, demographic, and economic reasons. 1 such change was an amendment restricting naturalization to Muslims, thereby not allowing naturalization of the growing Asian migration population, to preserve their cultural authenticity. By 1984, following 1 rebalance of the distribution of Kuwaitis and nonKuwaitis, economic declines, and security threats, migration policy shifted back to population balance. Kuwaiti history shows, however, that experimenting with migration policy and population balance cannot establish internal political and social cohesion. This is a revised version of a paper originally presented at the 1987 Annual Meeting of the Population Association of America (see Population Index, Vol. 53, No. 3, Fall 1987, p. 409).     

Individual Prior Information in a Physiological Model of 2H8-Toluene Kinetics: An Empirical Bayes Estimation Strategy

Physiologically-based toxicokinetic (PBTK) models are widely used to quantify whole-body kinetics of various substances. However, since they attempt to reproduce anatomical structures and physiological events, they have a high number of parameters. Their identification from kinetic data alone is often impossible, and other information about the parameters is needed to render the model identifiable. The most commonly used approach consists of independently measuring, or taking from literature sources, some of the parameters, fixing them in the kinetic model, and then performing model identification on a reduced number of less certain parameters. This results in a substantial reduction of the degrees of freedom of the model. In this study, we show that this method results in final estimates of the free parameters whose precision is overestimated. We then compared this approach with an empirical Bayes approach, which takes into account not only the mean value, but also the error associated with the independently determined parameters. Blood and breath ²H₈-toluene washout curves, obtained in 17 subjects, were analyzed with a previously presented PBTK model suitable for person-specific dosimetry. Model parameters with the greatest effect on predicted levels were alveolar ventilation rate Q_PC, fat tissue fraction V_FC, blood-air partition coefficient K_b, fraction of cardiac output to fat Q_a/co and rate of extrahepatic metabolism V_max-p. Differences in the measured and Bayesian-fitted values of Q_PC, V_FC and K_b were significant (p < 0.05), and the precision of the fitted values V_max-p and Q_a/co went from 11 ± 5% to 75 ± 170% (NS) and from 8 ± 2% to 9 ± 2% (p < 0.05) respectively. The empirical Bayes approach did not result in less reliable parameter estimates: rather, it pointed out that the precision of parameter estimates can be overly optimistic when other parameters in the model, either directly measured or taken from literature sources, are treated as known without error. In conclusion, an empirical Bayes approach to parameter estimation resulted in a better model fit, different final parameter estimates, and more realistic parameter precisions.

The Globalization of Penal Space in Nineteenth-Century Malta

In the second half of the nineteenth century an unprecedented number of prisons were built across the Western-influenced world. However, many more developed from repurposed and modified buildings. By applying space syntax analysis to examples from the then British colony of Malta, this article investigates the commonalities of penal space across a series of purpose-built and refashioned prisons, taking into consideration key architectural phases resulting from remodelling. Rejecting the notion that Maltese developments are merely symptomatic of British colonialism, the spread of Western prisons is cast in terms of wider trends and the global spread of a particular type of penal space.     

Dividing to keep muscle together: the role of satellite cells in aging skeletal muscle

The factors responsible for the atrophy of skeletal muscle with aging remain to be elucidated. Recent evidence points toward an important role for a population of cells located on the surface of skeletal muscle fibers, known as satellite cells, in maintaining the integrity of skeletal myocytes throughout the life span. This Perspective examines the role that these cells are thought to play in aging muscle atrophy, and highlights a recent study by Brack and colleagues that attempts to understand the role of satellite cells in maintaining the ratio of myonuclear number to cytoplasmic volume within myocytes as we age.     

Occupational safety and profit maximization: Friends or foes?

The rise of the Industrial Revolution is often depicted as a cause of hazardous working conditions and is skillfully epitomized in William Blake's tale of a child chimney sweeper. Conventional wisdom puts firm profit in conflict with occupational safety. We reexamine this argument noting that injuries are very costly to firms because they lead to higher wage premiums, worker compensation, and costly work stoppages. We hypothesize that it is precisely for these reasons that firms in the industries with dangerous working conditions have the strongest incentives to innovate and substitute more capital for labor. Using a longitudinal panel of U.S. industries, we test and confirm our hypothesis that higher injury rates lead to higher capital stock per worker, over time. Moreover, our estimates suggest that firms provide more capital and equipment per worker than what would have been there based solely on the compensating wage differential.
