The benefits to Caribbean Basin countries from the U.S. CBI tariff eliminations

The Caribbean Basin Economic Recovery Act eliminates U.S. tariffs on many exports of countries in the Caribbean Sea and Central America. This paper estimates the short-run effects of these tariff eliminations on the export earnings and economic welfare of the beneficiary countries. It is found that the tariff eliminations increase annual export earnings of beneficiaries by at most $81 million and provide annual welfare gains to these countries of $15 million to $24 million. The benefits are concentrated in agricultural products (particularly sugar, beef, and tobacco) and in products assembled from U.S. components for export to the United States (particularly electronic equipment). The countries that benefit most are the Dominican Republic, Panama, and Guatemala.     

Managing as a Performing Art

This paper considers the activities of senior managers as isomorphic with the activities of actors. It takes performing as not a matter of metaphor, but a matter of form; life at the top of an organization is intrinsically theatrical; each of us is blessed or cursed with histrionic sensibility. Proceeding by way of a comparison of Edmund Kean and Lee lacocca it touches upon matters of text and interpretation, rehearsal and performance and the importance of individuation. The argument – such as it is – is that both Kean and lacocca perform themselves, the former's Richard III, the latter's Chrysler being the fullest realizations of that which was, hitherto, inchoate and emergent. The final part of the paper is concerned with the implications of this perspective for education, training and development; current management education appears geared to reduce rather than to promote individuality. Techniques are imposed and answers are provided and the entire educational performance revolves around teachers as performers rather than managers as performers. The way to become a management star, it is suggested, is to do managing, not simply to be audience for academic stars.     

Relations between statistics for testing exponentiality and uniformity

It is shown that Greenwood's statistic for uniformity and the Hahn-Shapiro and Stephens statistics for exponentiality with known origin are equivalent. It is also shown that the distribution of the Shapiro-Wilk statistic for testing the hypothesis of exponentiality with unknown origin is obtainable from the distribution of Greenwood's statistic.     

Investigating the Effects of Trauma-Related Research on Well-Being

Using an experimental design, we investigated the impact of participation in trauma-related research on well-being in a sample of 219 higher education students. We created five conditions that exposed participants to questions about life events. A sixth condition represented a control condition. Exposure conditions varied according to whether they contained yes/no questions about events that entailed stress, stigma, trauma, or sexual violation. We operationalized well-being by measuring positive and negative affect, state anxiety, and positive reactions to research. Across exposure conditions, participants reported low levels of negative affect and generally positive reactions immediately after participation. The most negative and least positive responses followed exposure conditions that contained questions about stressful events and sexual violation. We discuss implications of our findings for ethics review board practices.

Where do underage college students get alcohol?

Alcohol consumption and related problems are common among underage college students, yet qualitative, in-depth information on how/where these students obtain alcohol is limited. We conducted focus groups pertaining to access to alcohol and related issues with 19 underage college students. They reported that alcohol is easy to obtain from a variety of sources, with friends/acquaintances who are of legal age or those with a false ID being the most common. Parties were also common sources, but "shoulder tapping" (i.e., asking a stranger to purchase alcohol) was not common. Disagreement arose over whether underage fraternity/sorority members have greater access to alcohol than non-Greeks. Our results provide updated information on the various sources of alcohol and associated issues among underage college students.     

Grandparents Responsible for Grandchildren in Native‐American Families*

Objectives. The primary goal of this article is to examine factors associated with grandparent care giving within the American Indian/Alaska Native (AIAN) population. Methods. Data from the 2000 Census of Population, 5% Public Use Microdata Sample, are used to evaluate a multivariate logistic regression model focusing on living with and caring for grandchildren. Particular emphasis is placed on characteristics that may reflect culturally‐based ideas about grandparents' responsibility for the care of their grandchildren. Results. Indicators related to Native‐American identity—specifically, reporting race as AIAN only rather than mixed race, reporting tribal membership, and living in a nonmetropolitan area of an “Indian” state—increase the likelihood of being responsible for a grandchild among Native‐American singles and couples aged 45 and over. Conclusions. Cultural and resource characteristics combine to produce high levels of grandparent care giving within the AIAN population. Inasmuch as those with lower educational and economic resources are especially likely to have responsibility for a grandchild, special attention should be directed toward ensuring adequate support for these caregivers.     

Can oral toxicity data for PFAS inform on toxicity via inhalation?

Per- and poly-fluoroalkyl substances (PFAS) are ubiquitous in the environment and are detected in wildlife and humans. With respect to human exposure, studies have shown that ingestion is the primary route of exposure; however, in certain settings, exposure via inhalation could also be a significant source of exposure. While many studies examined toxicity of PFAS via ingestion, limited information is available for PFAS toxicity via the inhalation route, translating into a lack of exposure guidelines. Consequently, this article examined whether route-to-route extrapolation to derive guidelines for inhalation exposure is appropriate for PFAS. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were used as exemplary PFAS given the abundance of toxicity data for these two compounds. Our evaluation determined that available toxicity and toxicokinetic data support route-to-route extrapolation for PFAS in order to derive inhalation-based standards. Results from this analysis suggest that an air concentration of 7.0 × 10⁻⁵ mg/m³ (or 0.07 μg/m³) would be an appropriate RfC for PFOA and PFOS assuming the 2016 EPA RfD of 0.00002 mg/kg-day, whereas use of the interim RfDs proposed in 2022 of 1.5 × 10⁻⁹ and 7.9 × 10⁻⁹ mg/kg would yield much lower RfCs of 5.25 × 10⁻⁹ and 2.77 × 10⁻⁸ mg/m³ (or 5.25 × 10⁻⁶ and 2.77 × 10⁻⁵ μg/m³) for PFOA and PFOS, respectively.
