ABSTRACT: This analysis documents the outcomes and impacts from a series of food protection and defense educational programs conducted over a 3‐y period for private and public sector food system professionals. Several measures were used to determine the professions of participants; their improvements in skills and abilities that resulted from workshops; the audiences' most valued program content; practice changes resulting from educational program participation; abilities to recognize and change food system vulnerabilities; and changes in knowledge levels. Findings indicate that the knowledge level and interest within the target audience progressed over the 3‐y period from basic awareness level through more complex and higher order skills and competencies such as being able to walk through a food production, processing, distribution, or retail facility and identify specific vulnerabilities and make specific risk control recommendations. Pre‐ and posttest scores from the 3rd y of educational activities indicate that baseline awareness levels of core content on food protection and defense is now high among those most likely to attend these types of events, and that participants need to be challenged with additional higher‐level education to promote specific skills. This program series proved successful in building important relationships among food industry and regulatory partners. Analysis of the food security investigation (FSI) series will be useful in the development and delivery of new education and outreach efforts. It is hoped that the analysis and discussion will provide the motivation to further develop a set of competencies that can be used to ground educational efforts that focus on securing and defending our food system.  相似文献   

Etiology of reading difficulties as a function of gender and severity     

Jesse L. Hawke  Sally J. Wadsworth  Richard K. Olson  John C. DeFries 《Reading and writing》2007,20(1-2):13-25

To test the hypothesis that the etiology of reading difficulties may differ for males and females in more severely impaired samples, reading performance data from monozygotic (MZ), same-sex dizygotic (DZ_ss), and opposite-sex dizygotic (DZ_os) twin pairs were analyzed using a model-fitting implementation of the DeFries-Fulker (DF) model (Purcell & Sham, 2003, Behavior genetics, 33, 271–278). Five non-independent samples were selected using cut-offs of −1 (N = 737 pairs), −1.5 (N = 654), −2 (N = 468), −2.5 (N = 335), and −3 (N = 198) standard deviations (s) below the mean composite reading score of control twins. Male/female gender ratios for children with reading difficulties were significantly higher than 1.0 for all five samples and increased as a function of severity (viz., 1.15, 1.17, 1.40, 1.61, and 1.88, respectively). When the DF model was fit to the data, estimates of heritability (h _g²) and shared environmental influences (c _g²) were not significantly different for males and females in any of the groups. Consequently, the most parsimonious model that provided a good fit to the data at all five levels of severity equated the heritabilities and shared environmental influences for males and females, and fixed the DZ_os coefficient of genetic relatedness at 0.5. Thus, these results provide no evidence for a differential etiology of reading difficulties as a function of gender in more severely impaired samples, and suggest that the same genetic and environmental influences contribute to reading difficulties in males and females, irrespective of severity.  相似文献   

“I Want to Feel That I Live in China”: Imaginaries and Hospitality in International Students’ (mis-)Encounters at a Top Chinese University     

Fred DERVIN  Anu HÄRKÖNEN  Mei YUAN  Wan ZHANG  Ning CHEN 《Frontiers of Education in China》2020,15(4):588

Research on international students’ experiences abroad has tended to rely on models of adjustment, integration and/or acculturation to describe their (mis-)encounters with different kinds of people (e.g., co-nationals, locals and other international students). This paper proposes to use the more fluid concepts of imaginaries and hospitality, leaving behind stages and phases of adaption and acculturation, and focusing on the influence of the Structure on their experiences. Based on a discursive pragmatic analysis of interview data with 20 international students at a top Chinese university, the authors review how the students describe the kind of hospitality experienced at this institution and the influence that it has on their (mis-)encounters. Culturalist, differentialist and essentialist imaginaries (static and fixed views of Chineseness) are often used to justify the lack of encounters and the “segregation” and somewhat “positive discrimination” that they experienced. However, the paper shows that, amongst others, the institutional hospitality management for international students leads to closed contexts of encounters and feelings of exclusion. Although the study serves as a case study and cannot be generalized to the many and varied experiences of international students in other universities in China, some recommendations are made to solve, at least in part, misconceptions about what interculturality and hospitality entail in the internationalization of higher education.  相似文献

Impact of Virtual Work Environment on Traditional Team Domains     

Gary D. Geroy  Jackie Hartman  Joel Olson 《Performance Improvement Quarterly》2002,15(3):11-42

An extensive literature review and a phenomenological heuristic case study examined a virtual work team to determine what were salient domains of the team and determine the effect the virtual work environment had upon these domains. The study determined that post‐modern philosophy and postindustrial society are linked to changes in the marketplace and the development of virtual work environments. Seven team domains were identified. The virtual work environment affects the communication domain of teams most strongly. This effect impacts the remaining domains. Decision processes were determined to be narrower and featured conformity. Effectiveness was shown to be diminished by the reduction of social facilitation and increase in social loafing. Leadership was affected by the change in the communication network from an all‐channel network to a wheel network. Relationship and trust were affected by erosion of trust. Roles changed with the team's reduced ability to resolve differences and execute detailed action. Purpose became more task‐oriented. Technology emerged in the study as the new virtual team domain. Factors involved in team members' satisfaction were related to personality, isolation, and team membership.  相似文献   

The Behavior Engineering Model at Work on a Small Scale: Using Task Clarification,Self‐Monitoring,and Public Posting to Improve Customer Service     

John Austin  Ryan Olson  Julie Ann Wellisley 《Performance Improvement Quarterly》2001,14(2):53-76

Gilbert's (1978/1996) Behavior Engineering Model (BEM) can enable the success of novice performance engineers by prompting appropriate front‐end analysis. This paper describes the third author's first performance improvement project conducted in the customer service department at an insurance agency. Front‐end performance analysis informed the design of an intervention package that addressed particular environment and person variables. This package included task clarification, employee self‐monitoring, and public posting of group performance. A multiple baseline design across behaviors was used to assess the effects of the intervention. The performance targets were: 1) the percentage of transactions where Customer Service Representatives (CSRs) used customer names, and 2) the percentage of transactions where CSRs suggested additional services available to customers. Average performance during intervention was more than 50% better than average baseline performance for both targets. Results are discussed in terms of the utility of the BEM as a front‐end analysis tool that can guide novice performance engineers to build simple and inexpensive, yet effective, performance improvement interventions.  相似文献

Examining Interprofessional Education Through the Lens of Interdisciplinarity: Power,Knowledge and New Ontological Subjects     

Rebecca E. Olson  Caragh Brosnan 《Minerva》2017,55(3):299-319

Interprofessional education (IPE) – students of different professions learning together, from and about each other – is increasingly common in health professional degrees. Despite its explicit aims of transforming identities, practices and relationships within/across health professions, IPE remains under-theorised sociologically, with most IPE scholarship focussed on evaluating specific interventions. In particular, the significance of a shared knowledge base for shaping professional power and subjectivity in IPE has been overlooked. In this paper we begin to develop a framework for theorising IPE in allied health, by drawing parallels with a cognate area in which there has already been fruitful conceptual development: interdisciplinarity. Specifically, we offer a worked example of how the two areas may be brought into dialogue, by deploying Barry, Born and Weszkalnys’ (2008) conceptualisation of interdisciplinarity as a lens for understanding IPE. Following Barry et al. (2008) we delineate a number of ‘modes’ and ‘logics’ of knowledge-production that emerge both in IPE literature and in our own empirical study of IPE. Our empirical data are drawn from 32 semi-structured interviews with 19 allied health students participating in an IPE curriculum at one Australian university. Findings point to the emergence of interprofessional practitioner identities among students that have the potential to undermine traditional epistemological boundaries and transcend role-based distinctions in future health profession(al)s. We argue that Barry et al.’s ‘logic of ontology’ sheds light on previously unidentified processes of transformation within IPE, and offers a theoretical framework that can explain the importance of a shared pan-professional knowledge base for the reflexive individual construction of new interprofessional ontological subjects.  相似文献   

The effects of gender on the transition of transfer students into a new school     

Bart L. Pillen  Leonard A. Jason  Thomas Olson 《Psychology in the schools》1988,25(2):187-194

The present study describes a peer-tutoring program designed to utilize computerassisted instruction to help first through fourth graders who were entering a new school. Tutored girls increased their positive self-perceptions as a result of the tutoring program, whereas boys declined in positive self-perceptions, while exhibiting gains in reading scores. These findings suggest that prevention efforts need to consider the specific adaptation needs of transfer students by gender so as to insure a maximum fit between individual need and program scope.  相似文献   

SABCO—An experiential learning project for introductory managerial accounting     

Jodi Olson  Kimberly Shannon 《Decision Sciences Journal of Innovative Education》2023,21(3):144-166

This teaching brief presents a capstone project designed to provide students with a contextual understanding of introductory management accounting theories through hands-on, experiential learning. It also exposes them to cross-disciplinary roles from operations management. Using this capstone approach, students quickly learn to prepare financial projections, either manually or in Microsoft Excel, to secure financing for their start-up business (Sand Art Brownie Company or SABCO) to produce and sell brownie mix during the holiday season. Students then assemble ingredients and create jars of brownie mix to gather the necessary data to evaluate initial projections and problem-solve for future production. This role play contextualizes the elements of direct and indirect labor, fixed and variable costs, and their impact on profit and borrowing. Postproduction reflection on the manufacturing activities and discussion of actual results of operations emphasizes the improvement and decision-making responsibilities in the management process. Feedback demonstrates that students find the exercise challenging and valuable and that it deepens their understanding of managerial accounting and its purpose in a company's management process.  相似文献
