Using the United States Census Data to Introduce Differential Equations

Abstract

This article describes a method for using the United States Census data to open a differential equations course. The question of finding a model for the United States population data gives students a first experience with creating a model using differential equations, and also understanding derivatives, what they mean, and how to calculate them in the context of real data. This model-building start motivates further exploration in many of the standard differential equations topics: the method of separation of variables, slope fields, autonomous equations, equilibria, and stability.     

The Experience of Columbian Child Soldiers from a Resilience Perspective

There are child soldiers fighting with government forces and opposition groups in more than 30 countries worldwide. Although studies have been conducted on the impact of war-related trauma on children, very few have focused on those children who do not exhibit trauma-related symptoms after experiencing armed combat. The purpose of this study was to identify and understand some of the mechanisms and resources that resilient children draw upon to overcome the trauma of child soldiering. Six Colombian child soldiers were recruited through purposive sampling techniques to participate in a narrative study focusing on their lived experiences and their personal understanding of how they were able to overcome the effects of war trauma. Six narrative themes were identified and discussed in terms of the literature on trauma and childhood resilience and also related to counselling needs and services.     

Afro-Caribbean Immigrant Faculty Experiences in the American Academy: Voices of an Invisible Black Population

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.     

Seeing Is Believing: Effective Components of Professional Development Training for County Extension Educators on an Innovation Perceived as Risky—Food Irradiation

ABSTRACT: Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer sciences county extension educators' understanding of food irradiation. This training included presentations by experts in the field, a tour of a food irradiation research facility and a meat processing facility, group activities, and a computer simulation model. Data were collected using qualitative research methodology through in-depth interviews conducted after the training. Results indicated that those components that allowed participants to visualize food irradiation processes seemed most beneficial to their understanding. Based on these data, implications for practice are discussed.     

Opportunity structures and educational marginality: the post-16 transitions of young people outside education and employment

This paper reports on findings from a three-year ethnographic study of 24 young people in northern England who were classified as not in education, employment or training (NEET), or at risk of becoming so. Drawing on conceptions of opportunity structure and educational marginality, the paper discusses the processes leading to young people becoming NEET after leaving school. It presents findings concerning the family backgrounds, school experiences, and educational attainment of participants, and traces their initial post-16 destinations and their pathways to NEET status. Although most participants did not become NEET immediately after leaving school, restricted labour market opportunities and a lack of high-quality education and training for middle- and low-attaining young people exacerbated social and educational disadvantage. Over time, participants became increasingly restricted to marginal forms of learning. The paper argues that a focus on opportunity structures provides a powerful way of understanding these processes, and that alongside sustained NEET status, educational marginality should be of equal concern to policy makers.     

Racial Identity Theory and Peace Education: Tools for the Teacher In All of Us

As people develop a meaningful understanding of racism, they also experience shifts in their appraisals of self and others as members of an unfairly stratified society. Consistent with the premises of Helms' (1995) racial identity theory, these shifts can be explained as transformational processes that have relevance to matters of morality and peace advancement. Individuals who operate at advanced levels of racial identity development overcome the confinements inherent in a racism Zeitgeist and in so doing, learn to accept themselves and others more authentically. This theory can prove crucial to peace promotion in children because it espouses to nurture the integration of self within the broader spectrum of humanity. Educators who transform their selves can also transform their educational practices by disrupting cycles of socialization that adversely influence children's identity formation. They can also contribute to the creation of new structures of socialization. In this paper, I describe this theory and how it applies to peace education.     

Culture, Climate, and Contribution: Career Satisfaction Among Female Faculty

Retention of female faculty is an important issue for institutions of higher education aiming for excellence and diversity. However, an essential first step in understanding retention is to examine what contributes to career satisfaction for academic women. This study is based on data from a census survey of faculty conducted in 1996 at a Research I university located in the Midwest. Using Hagadorn's (2000) model for conceptualizing faculty job satisfaction, the study identifies domains of environmental condition, departmental climate, and demographics that play a role in female faculty's overall career satisfaction.
