Factors associated with one-year retention in a community college

This study sought to evaluate preenrollment variables as predictors of one-year retention of first-time students in a community college. The purpose was to use information that is typically available when a student begins his or her college program and determine if this information can help identify students who are more likely to drop out within their first year. Based on a logistic regression model to select predictors of retention, the lower the high school GPA, the greater the chance the student will drop out. Over and above this, additional risk is associated with the age range 20–24, attending part-time, and being an ethnic minority other than Asian. When all or some of these are operating, it may be necessary to enhance these students' chances with special programs or services.     

Cumulative childhood trauma and psychological maladjustment of sexually abused children in Korea: Mediating effects of emotion regulation

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6–13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma.     

Evaluating Corrective Feedback Self‐Efficacy Changes Among Counselor Educators and Site Supervisors

Analysis of pretest–posttest scores on the Corrective Feedback Self‐Efficacy Instrument (Page & Hulse‐Killacky, 1999 ) following a supervision workshop indicated a significant positive relationship between workshop training and supervisors' feedback self‐efficacy in giving corrective feedback. Furthermore, the association between prior supervision training, supervision experience, and feedback self‐efficacy was measured. Practical and research implications are discussed.     

Teaching Lean Six Sigma within A Supply Chain Context: The Airplane Supply Chain Simulation

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.     

Poly(vinyl alcohol)-heparin biosynthetic microspheres produced by microfluidics and ultraviolet photopolymerisation

Biosynthetic microspheres have the potential to address some of the limitations in cell microencapsulation; however, the generation of biosynthetic hydrogel microspheres has not been investigated or applied to cell encapsulation. Droplet microfluidics has the potential to produce more uniform microspheres under conditions compatible with cell encapsulation. Therefore, the aim of this study was to understand the effect of process parameters on biosynthetic microsphere formation, size, and morphology with a co-flow microfluidic method. Poly(vinyl alcohol) (PVA), a synthetic hydrogel and heparin, a glycosaminoglycan were chosen as the hydrogels for this study. A capillary-based microfluidic droplet generation device was used, and by varying the flow rates of both the polymer and oil phases, the viscosity of the continuous oil phase, and the interfacial surface tension, monodisperse spheres were produced from ∼200 to 800 μm. The size and morphology were unaffected by the addition of heparin. The modulus of spheres was 397 and 335 kPa for PVA and PVA/heparin, respectively, and this was not different from the bulk gel modulus (312 and 365 for PVA and PVA/heparin, respectively). Mammalian cells encapsulated in the spheres had over 90% viability after 24 h in both PVA and PVA/heparin microspheres. After 28 days, viability was still over 90% for PVA-heparin spheres and was significantly higher than in PVA only spheres. The use of biosynthetic hydrogels with microfluidic and UV polymerisation methods offers an improved approach to long-term cell encapsulation.     

Insights into inclusive education through a small Finnish case study of an inclusive school context

This study seeks to present data and discussion arising from a case study of a school in Finland renowned for its practice in the inclusion of learners with additional support requirements due to cognitive and physical disabilities. It aims to establish how the school staff understand their practice with inclusion through day-to-day professional experiences. The process of reflexive dialogue has enabled authors to reconceptualise our understanding of inclusive education through gaining deep contextual insight. The case study emerges as an inspiring effort to reduce exclusion and isolation through skilful manipulation of physical, institutional and communicative contexts, from which we may draw valuable lessons. The case study demonstrated high levels of personal motivation in teachers and assistants, used as a force for participation in inclusive education – bottom-up, via dialogue, consultation, voluntary involvement and transformation by exposure. This democratic approach was evident in and supported through leadership and management, teaching and learning, and the involvement of the wider community.     

The textbook problem: Investigating one possible solution

This article explores the inherent problems for academic libraries in providing access to textbooks to students, the growing demand for such access by students, and presents the findings of a reserve pilot project conducted at a major Midwest university. Findings indicate the pros and cons of the pilot attempted as well as demonstrating the need for continued research and collaborative work with appropriate organizations on the campus and beyond.
