USA Dairy Industry and Producer Views the International Dairy Federation

Although not to be construed as an official position of the United States dairy industry, observations (pro and con) on how the United States views the International Dairy Federation were presented. A proposal suggested by industry members, and holding the support of the International Dairy Federation, was outlined. The proposal embraces the formation of an Interim National Committee of the International Dairy Federation in the United States of America.     

Model tests of turbine missile impact on reinforced concrete

The results of 25 impact tests on 1/11-scale models of reinforced concrete nuclear plant walls are presented. These tests determined experimentally the maximum velocity at which postulated turbine missiles are contained by typical reinforced concrete walls. The parameters varied were missile weight, velocity, orientation, and impact angle, as well as target design and thickness. The results showed that the NDRC perforation formula used extensively in current practice is overly conservative, whereas a newer empirical formula (CEA-EDF) gave reasonably conservative predictions of the test results. All but the most energetic postulated missiles are stopped by containment wall models, and steel liners on these walls are effective in suppressing backface concrete scabbing.     

Development of seismic anchorage guidelines for nuclear plant equipment

Seismic anchorage guidelines have been developed for various classes of electrical and mechanical equipment typically found in nuclear power plants. The guidelines consist of tables and charts that give the seismic capacity of anchorage configurations as a function of the type, number, size, and location of fasteners and the dimensions of the equipment. Seismic anchorage capacities have been derived using a conventional static analysis but with more realistic assumptions and strength criteria than typically used for design. The guidelines also include simple and practical inspection procedures for verifying proper installation of existing equipment anchorages.     

Overview of EPRI research in structural integrity

This paper is an overview of the structural integrity research within the Nuclear Safety and Analysis Department of the Electric Power Research Institute. This research addresses structurally related safety issues in light water reactors. Five major technical areas are covered: Analysis/Design Methods, Seismic/Vibratory Response, Fluid/Structure Response, Impact/Impulse Response, and Structure/Component Performance. Each technical area is briefly described and research results are highlighted. This paper puts in perspective the research and development work described in this special issue of the journal in addressing such safety and licensing issues as soil-structure interaction, seismic response of piping systems, hydrodynamic loads in pipes and vessels, pipe rupture and whip, jet impingement, missile impact, and concrete containment integrity.     

How rude! Emotional labor as a mediator between customer incivility and employee outcomes.

Because of the large number of people employed in service occupations, customer incivility has become an increasingly prevalent and important workplace stressor. Unfortunately, relatively little research has examined the effects of customer incivility; of the research that does exist, virtually all of it has focused solely on employee mental health outcomes. The present study was designed to replicate previous research linking customer incivility to the emotional exhaustion dimension of burnout and to expand on previous research by examining the effects of customer incivility on customer service quality. In addition, two models were proposed and tested in which emotional labor mediated the relationship between customer incivility and outcomes. Data from 120 bank tellers revealed that customer incivility was positively related to emotional exhaustion and negatively related to customer service performance. In addition, both proposed models were supported. Theoretical and practical implications of the findings and future directions are discussed.

Full-scale tornado-missile impact tests

Full-scale poles, pipes, and rods, representing postulated tornado-borne missiles, were rocket-propelled into reinforced concrete panels with thicknesses typical of walls and roofs in the auxiliary buildings of nuclear power plants. Data from the 18 tests can be used directly for structural design or for validating design and analysis techniques. The test panels, constructed with 3000-psi design strength concrete and minimum allowable reinforcement, were 12, 18, and 24 in. thick with 15 × 15-ft unsupported spans. The results show that a 1500-lb utility pole, 1-in rod, and 3-in. pipe are ineffective for producing significant local and structural damage even under the improbably severe tornado-missile impact conditions represented by the tests. The front several feet of the poles disintegrated upon impact without damaging the face of the panels. Although 12-in. pipes produced craters in the face of the panels, impact tests with these missiles showed that 18-in. thick walls are adequate for preventing backface scabbing (secondary missiles) in the highest tornado-intensity region of the US, while 12-in. thick walls are adequate in other regions. Data on penetration depths and scabbing thresholds for 12-in. pipe impacts could be fitted reasonably well only with a modified NDRC design formula. Examination of structural response was aided by electronic records of reaction forces, missile deceleration, panel velocity, and strains during impact. Contrary to the predictions of conventional structural design methods, which do not account for missile deformation, no overall permanent deflections of the panels were produced by any of the missiles.     

The differential effects of interpersonal conflict from customers and coworkers: Trait anger as a moderator.

Interpersonal conflict (IC) at work is a frequently experienced type of workplace mistreatment that has been linked to a host of negative workplace outcomes. Previous research has shown that IC can have differential effects based on source, but this has not yet been investigated in terms of customer IC versus coworker IC. To remedy this oversight in the literature, we used a multimethod, multitime point design to compare IC from customers and coworkers experienced by 75 call center employees. Primarily, we investigated burnout, physical health symptoms, and task performance. Results indicated that customer IC was more strongly related to both personal and organizational outcomes. Additionally, trait anger was investigated as a moderator of these relationships, and the results indicated that people who are easy to anger may be more likely to experience negative effects as a result of customer IC. Implications of these findings, limitations, and areas for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
