An American BSE Crisis: Has it affected the Value of Traceability and Country-of-Origin Certifications for US and Canadian Beef?

With a BSE incident in the United States (US) in December of 2003, questions arose about the effect of the incident on consumers in the US. The purpose of this paper is to determine if traceability systems for beef can help preserve consumer demand following the discovery of BSE. Auctions were conducted approximately 3 weeks before and after the December 2003 BSE incident in the U.S It was found that overall there was no effect on the size of the bribes needed by the BSE incidence. However, for some groups there were important changes. The results indicate that information about traceability and country of origin is valuable to consumers. They also suggest that greater uncertainty about certifications and assurances for beef existed among the participants after December 23rd than before December 23rd.BSE, Traceability, Country-of-origin, Beef market, Auctions, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,

Analysis of Disproportionality in Discipline and the Effects of Positive Behavior Supports Within Special Education

Nationwide, school districts are required (IDEA, 2004) to implement positive behavior interventions and supports (PBIS) for all students receiving special education services. These PBIS are reported to reduce problem behaviors and increase prosocial behaviors when implemented with fidelity (Crone et al., 2015). With a reduction of problem behaviors an expected reduction of discipline referrals should follow along with a reduction in days spent in exclusionary discipline for students in special education. Reducing days in exclusionary discipline is desired due to a strong research base linking the practice to several negative outcomes (Marchbanks et al., 2015) along with data demonstrating these negative outcomes are disproportionally experienced by minority and disabled students (DOE, 2018). The goal of the current study was to: 1) describe the discipline practices of a school district for students in special education, and 2) analyze the effectiveness of Tier 3 PBIS in reducing exclusionary discipline for students in special education. It was hypothesized that students receiving Tier 3 PBIS and students with more accurate behavior intervention plans (BIPs) would spend fewer days in exclusionary discipline. Results demonstrated that Black and ED students were at the highest risk for receiving exclusionary discipline and that students in special education receiving any Tier 3 PBIS spent more days in exclusionary discipline than students who did not receive Tier 3 PBIS. However, students with accurate BIPs did spend fewer days in exclusionary discipline

Occupational Stress Among Nurse Administrators in General Hospitals in Tennessee

The purpose of this study was to determine the level of occupational stress among nurse administrators and to identify the types of strategies used by nurse administrators to deal with or manage occupational stress. The study examined the relationship between selected demographic variables, occupational stress, and strategies. The research design included five research questions along with seven null hypotheses testing the relationship between occupational stress and demographic variables--age, gender, marital status, years of professional nursing experience, years as a nurse administrator, educational attainment, and hospital bed capacity. There were seven additional hypotheses testing the relationship between the same demographic variables and three categories of coping strategies. The instrument used included the researcher-designed Demographic Questionnaire, the Health Professions Stress Inventory (HPSI), and a listing of 17 coping strategies. Nurse administrator\u27s HPSI overall mean stress score was lower than the HPSI mean stress level scores reported for nurses in previous studies. Five subscales of stressors (Stress Factors) were identified by analyzing the HPSI using Principal Components Factor Analysis. A statistical significant difference (p $\u3c$.05) was revealed for nurse administrators for: (1) overall stress level when tested by three of the demographic variables, years as a nurse administrator, educational attainment, and hospital bed capacity; (2) subscale level of stress when testing the HPSI five stress factors by marital status, years as a nurse administrator, and educational attainment. A statistical significant difference (p $\u3c$.05) for strategies used by nurse administrators was revealed with testing: (1) Avoidance strategy by demographic variables--age, number of years of professional experience, number of years as a nurse administrator, and hospital bed capacity and, (2) Active Cognitive strategy by demographic--gender. The Spearman Rho correlation coefficient procedures used to correlate the HPSI five Stress Factors with Active Cognitive, Active Behavioral, and Avoidance strategies revealed: (1) Stress Factor 1, Professional Conflicts was significantly related to Avoidance strategy (r\sb{\rm s} =.24). (2) Stress Factor 2, Lack of Recognition as a Professional, was negatively significantly correlated with Active Cognitive Strategy (r\sb{\rm s} = $-$.22). (3) Stress Factor 3, Work Overload, was significantly related to Active Cognitive strategy (r\sb{\rm s} =.23). (4) Nurse administrators overall stress was significantly related to Avoidance Strategy (r\sb{\rm s} =.28)

Preliminary Design of JML: A Behavioral Interface Specification Language for Java

JML is a behavioral interface specification language tailored to Java(TM). Besides pre- and postconditions, it also allows assertions to be intermixed with Java code; these aid verification and debugging. JML is designed to be used by working software engineers; to do this it follows Eiffel in using Java expressions in assertions. JML combines this idea from Eiffel with the model-based approach to specifications, typified by VDM and Larch, which results in greater expressiveness. Other expressiveness advantages over Eiffel include quantifiers, specification-only variables, and frame conditions. This paper discusses the goals of JML, the overall approach, and describes the basic features of the language through examples. It is intended for readers who have some familiarity with both Java and behavioral specification using pre- and postconditions

A Multicultural-Multidisciplinary Approach to Speech/Language Intervention with Black Children

There is no better way to teach African-American children than through their dialect. Yet, American schools generally respond to the language needs of black youth inappropriately. This conference presentation focuses on appropriate educational practices that support the language and cognitive development of African-American children, and the ways in which special education, speech, and language professionals can work with teachers to alter black children\u27s school environments. The introduction, Part I (Ruby Burgess), emphasizes the influence of cultural differences on students\u27 success or failure in school. Part II (Nola Burl) delineates characteristics of the multidisciplinary team approach and implications for language intervention with black children. Discussion concerns the present implementation of the approach and the role of the speech-language pathologist as a multidisciplinary team member in establishing practices that support black children\u27s language acquisition. The section concludes with an overview of current perspectives on language that are consistent with a multicultural perspective. Part III (Ralph Calhoun) explores the role of the special educator as it relates to language instruction and advocacy for African-American children. Concluding comments summarize goals and directions for multicultural education and list critical actions that need to be taken in implementing nonracist practices

Preliminary Design of JML: A Behavioral Interface Specification

JML is a behavioral interface specification language tailored to Java. It also allows assertions to be intermixed with Java code, as an aid to verification and debugging. JML is designed to be used by working software engineers, and requires only modest mathematical training. To achieve this goal, JML uses Eiffel-style assertion syntax combined with the model-based approach to specifications typified by VDM and Larch. However, JML supports quantifiers, specification-only variables, frame conditions, and other enhancements that make it more expressive for specification than Eiffel. This paper discusses the goals of JML, the overall approach, and describes the language through examples. It is intended for readers who have some familiarity with both Java and behavioral specification using pre- and postconditions
