The Impact of Immigration on Wage Dynamics: Evidence from the Algerian Independence War

This paper investigates the dynamics of wage adjustment to an exogenous increase in labor supply exploiting the sudden and unexpected inflow of repatriates to France resulting from Algerian independence in 1962. I measure the impact of this particular supply shift on the average wage of pre-existing native workers across French regions between 1962 and 1976. I find that regional wages decreased between 1962 and 1968, before returning to their pre-shock level 15 years after. I also investigate the dynamics of skill-specific wages in response to the regional penetration of repatriates and find that the wages of high and low educated native workers declined initially but fully recovered by 1976.

Credibility and Incredulity in Milgram’s Obedience Experiments: A Reanalysis of an Unpublished Test

This article analyzes variations in subject perceptions of pain in Milgram’s obedience experiments and their behavioral consequences. Based on an unpublished study by Milgram’s assistant, Taketo Murata, we report the relationship between the subjects’ belief that the learner was actually receiving painful electric shocks and their choice of shock level. This archival material indicates that in 18 of 23 variations of the experiment, the mean levels of shock for those who fully believed that they were inflicting pain were lower than for subjects who did not fully believe they were inflicting pain. These data suggest that the perception of pain inflated subject defiance and that subject skepticism inflated their obedience. This analysis revises our perception of the classical interpretation of the experiment and its putative relevance to the explanation of state atrocities, such as the Holocaust. It also raises the issue of dramaturgical credibility in experiments based on deception. The findings are discussed in the context of methodological questions about the reliability of Milgram’s questionnaire data and their broader theoretical relevance.

Experimental Investigation on the Feasibility of Using Spring-Loaded Pogo Pin as a Holding and Release Mechanism for CubeSat’s Deployable Solar Panels

A spring-loaded pogo pin as a holding and release mechanism of solar panels for cube satellite applications is proposed which functions as an electrical interface, a separation spring, and a status switch. The proposed mechanism has many advantages, including an increased loading capability, negligible induced shock level, synchronous release of multiple panels, and handling simplicity during integration. A demonstration model of the mechanism was fabricated and functionally tested under various test conditions such as different input voltages, different numbers of tightened nylon wires, and different temperatures (ranging from −40°C to 70°C).

Alcohol and Unpleasant Stimulation: Subjective Shock Calibration and Pain and Discomfort Perception

In an experiment 8 men participated in an alcohol and a sober condition in a rotated order. In both conditions subjects first calibrated a shock scale to a subjective criterion and then rated their subjective pain and total discomfort. Subjects calibrated the shock scale higher when intoxicated and rated the calibrated level equally painful in the sober and intoxicated conditions, but when intoxicated subjects actually rated the higher shock level as less uncomfortable. The shock scale was calibrated higher under intoxication not because subjects wanted to impress the experimenter but because less pain and discomfort was actually experienced.

Review of effects of shock (<60 kbar; <6x109 Pa) on magnetism of lunar samples

Experimental shock studies of highland and mare soils in the range of a few to 50 kbar (5 x 109 Pa) have given the following results: (1) Shock, if less than 20 kbar, does not change the magnetic characteristics of the soil substantially and only weak and unstable shock remanence is generated in a field of 0.5 Oe. (2) Shock of between 20 and 50 kbar lithifies the soil and gives rise to stable shock remanence. Acquisition is approximately linear in field for a given shock level. At 30 kbar the acquisition parameter for the highland soil was 10-5 G cm3 g-1 Oe-1. In this range of 20-50 kbar the products of shock are petrologically and magnetically similar to certain regolith breccias. (3) Shock demagnetization preferentially demagnetizes the softer part of thermoremanent magnetization (t.r.m.) and hence makes it relatively harder. The significance of these results is that shock remanence is likely to be the cause of the natural remanent magnetization (n.r.m.) of certain regolith breccias and shock may modify the primary remanence of other samples.

Thresholds of response to electric shock in previously undernourished rats

1. Rats were undernourished in early life by feeding their mothers a restricted quantity of a good-quality diet during pregnancy and lactation. All offspring were fed ad lib. from weaning. Behavioural tests were done using adult males.2. Thresholds of aversion to electric shock were determined in a rectangular box, one side of which was designated ‘live’ and the other ‘safe’ (o V side) for any particular shock level. Three 15 min sessions were given at each of five shock levels. Previously undernourished rats had a lower aversion threshold than controls. They spent more time than controls on the o V side at two intermediate levels of shock.3. Other male rats were subjected to six graded series of brief, unavoidable shocks. Previously undernourished rats responded to a greater total number of shocks than controls.4. These results support the hypothesis that previously undernourished rats have a lowered threshold of arousal.
