H-1Bs: How Do They Stack Up to US Born Workers?

Combining unique individual level H-1B data from U.S. Citizenship and Immigration Services (USCIS) and data from the 2009 American Community Survey, we analyze earnings differences between H-1B visa holders and US born workers in STEM occupations. The data indicate that H-1Bs are younger and more skilled, as measured by education, than US born workers in the same occupations. We fail to find support for the notion that H-1Bs are paid less that observationally similar US born workers; in fact, they appear to have higher earnings in some key STEM occupations, including information technology.temporary workers, H-1B, immigration, high-skill, STEM

Did Employer Sanctions Lose Their Bite? Labor Market Effects of Immigrant Legalization

Taking advantage of the ability to identify immigrants who were unauthorized to work prior to obtaining Legal Permanent Resident status, we use the New Immigrant Survey to examine whether lacking legal status to work in the U.S. constrains employment outcomes of illegal immigrants. With the exception of high-skilled unauthorized immigrants, the data fail to reveal evidence of improved employment outcomes attributable to legal status. In light of evidence that unauthorized immigrants experienced increased wages as a result of receiving amnesty through the 1986 Immigration and Reform Control Act during the 1990s, we interpret the results as evidence of ineffective employer sanctions.unauthorized, illegal, undocumented, immigration, legalization, amnesty

The Effects of Shock-induced Attack on Bar Pressing for Liquid Food Reinforcement

Induced attack was studied under three conditions: (1) paired experimentally naive rats were exposed to intense electrical shock; (2) experimental subjects, previously trained to respond on a fixed vii ratio of six responses for liquid food reinforcement, were paired with target animals with the reinforcement contingency in effect; (3) experimental subjects were given a history of responding on a fixed ratio of six responses for positive reinforcement in the presence of shock, and finally this group was paired with experimentally naive targets when both the reinforcement and shock variables were present. Pairing experimental animals without shock did not cause attack, nor was bar-pressing behavior appreciably disrupted. Only when electrical shock was imposed upon pairs did attack occur. Furthermore, attack behavior severely reduced operant responding and there appeared to be no recovery of response rates over several sessions

Towards a Formal Theory of Humor in Organizations

Current theories and models of humor conceptualize humor at the individual, dyadic, and organizational level. These theories laid the foundation for research and empirical findings that have established humor’s impact in the workplace. Yet, because these theories are not integrated, they individually do not offer a comprehensive view of humor in the workplace across different levels, hindering the development of multilevel research designs. Additionally, the ambiguity of these narrative theories hampers empirical testing precision. This dissertation expands the literature by introducing a mathematical, multilevel model of humor and tests that theory using computational simulation methods. Synthetic environments reproduced observed correlations in the humor literature, showing generative sufficiency. Further, virtual explorations of follower impression management towards leader humor revealed that impression management tactics greatly impacted leader learning of follower humor preferences. Investigations into newcomer socialization in established humor climates showed that newcomer goals influenced group acceptance. Impacts of this dissertation include adding multilevel theory to the literature, making theory more communicable via mathematics, the novel explanation of the process of choosing to share humor, clarity for humor terms, and sharable computational modeling that offers precision for future investigations. Practical applications suggest leaders looking to use humor should build trusting relationships and that organizations hoping to dismantle hateful humor climates (e.g., racist or misogynistic joking) need to engage in active discourse. Together, the presented formal model of humor and computational simulation of that model propel the workplace humor literature forward

Study of diphtheria, with special reference to preventive measures

When one considers with these facts the frequency of paralysis and of permanent hypermetropia, the loss to the cause of education through school closure or exclusion, let alone the tremendous cost to the State of hospital accommodation for this disease ---when one considers these facts, I say, one finds great incentive for work on this disease which Sir George Newman rightly terms one of the most baffling from the point of view of the Public Health administrator.A well-defined etiology, a comparatively easy bacteriological diagnosis, a specific anti-serum with generally recognised prophylactic and curative powers - - - ail these are ours; yet this disease breaks out and rages amongst the population more than ever; and in this thesis I propose to describe my work in connection with Diphtheria, hoping that some little light may be thrown on this very important subject
