Positive Effects of Converting a Food and Bioprocessing Analysis Course to an Inquiry‐Guided Approach

Abstract: Food science laboratory courses are traditionally taught as a series of preplanned laboratories with known endpoints. In contrast, inquiry‐guided (IG) laboratories allow students to ask questions, think through problems, design experiments, then adapt and learn in response to unexpected results. This study examined the effects of converting the course, “Analytical Techniques in Food and Bioprocessing Sciences” from a traditional approach (2008 to 2010 data) to an IG approach (2011 data) by assigning teams of 2–3 students a food and a set of 5 analyses to conduct over the course of the semester. Students were required to choose and justify the use of specific methods for each analysis, as well as to develop a supply list and a budget for the semester‐long project. During the semester, students were required to post and discuss their weekly progress with the instructor, teaching assistants, and the rest of the class using an online discussion forum. At the end of the semester, students were required to present the results of their analysis in both oral and written formats. Overall course grades were significantly higher (P≤ 0.05) using IG in 2011 compared to 2010 and 2009, but not to 2008 grades. Numerical course evaluations for the instructor, overall course, and lab, as well as written course evaluations all significantly (P≤ 0.05) improved. This suggests that an IG approach may measurably improve student performance in terms of course grades and the ability to complete semester long projects. It may also increase student satisfaction with the course, as measured by numerical and written end of semester surveys.     

Disorganized Behavior in Adolescent–Parent Interaction: Relations to Attachment State of Mind,Partner Abuse,and Psychopathology

Disoriented, punitive, and caregiving/role‐confused attachment behaviors are associated with psychopathology in childhood, but have not been assessed in adolescence. A total of 120 low‐income late adolescents (aged 18–23 years) and parents were assessed in a conflict‐resolution paradigm. Their interactions were coded with the Goal‐Corrected Partnership in Adolescence Coding Scales. Confirmatory factor analysis demonstrated that the three disorganized constructs (punitive, caregiving, and disoriented interaction) were best represented as distinct factors and were separable from a fourth factor for collaboration. The four factors were then assessed in relation to measures of attachment disorganization, partner abuse, and psychopathology. Results indicate that forms of disorganized behavior first described in early childhood can also be reliably assessed in adolescence and are associated with maladaptive outcomes across multiple domains.     

Factors affecting disclosure among Israeli children in residential care due to domestic violence

Disclosure of child abuse may enable initiating interventions to end maltreatment and mediate its negative physical and psychological consequences. The present study reviews the field of disclosure and examines factors affecting disclosure among a service population of abused children who were placed in residential care due to various forms of abuse (e.g., physical, sexual, emotional, neglect and witnessing domestic violence). The sample consisted of 286 Israeli (Hebrew and Arabic speaking) children aged 12–17 (mean = 14 ± 1). Following approval of the Ethics committee of the University and parents’ written consent, participants were administered a self-report questionnaire that included the following measures: a Socio-Demographic Questionnaire, the Childhood Trauma Questionnaire (CTQ), the Juvenile Victimization Questionnaire (JVQ), and the Disclosure of Trauma Questionnaire (DTQ). Results indicated that the three key factors enhancing the likelihood of disclosure were: moral factors, external initiatives and intolerable physical pain. The three key factors inhibiting disclosure were feelings of shame, fear of losing social support and uncertainty as to how and to whom to disclose. Results also showed that children preferred to disclose to their nuclear family members (parents and siblings) in comparison with professionals.

“New” Holistic Mass Media Business Model

This qualitative case study, based on the principles of grounded theory, develops a holistic business model for media outlets by investigating the organizational structure and corporate culture of a unique agricultural radio station that operated successfully for over 60 years. It examines the station in the context of its founding era and determines the process used to create this survivor. An inductively generated “theory of commitment” is proposed, and guidelines are provided that could help today's independent media start-ups become survivors.
