In search of consolidation of short-term memory in nonhuman animals

Wixted (Annual Review of Psychology, 55, 235 – 269, 2004) has argued that forgetting is due to consolidation failure. Previous research with humans and nonhuman animals has reported evidence for consolidation in intermediate or long-term memory (LTM). The present study examines whether consolidation occurs in short-term memory in pigeons. Delayed matching-to-sample accuracy was reduced when retroactive interference (an extraneous task in Experiment 1 or houselight illumination in Experiment 2) was interpolated in the retention interval. Accuracy was not greater, however, when interference occurred at the end of the retention interval, as compared with when it occurred at the beginning. That is, there was no evidence for consolidation in short-term memory for pigeons. We did find, however, the beginning–end effect originally reported by Roberts and Grant (Journal of Experimental Psychology: Animal Behavior Processes, 4, 219–236, 1978) and the recovery from forgetting reported by White and Brown (Journal of the Experimental Analysis of Behavior, 96, 177–189, 2011). The results are discussed in relation to temporal distinctiveness theory as an alternative to consolidation.     

Fostering Student Engagement and Collaboration with the Library: Student Creation of LibGuides as a Research Assignment

This article describes a project using a student-created LibGuide in conjunction with a literature review assignment for a research course. This collaborative project between a librarian and a professor of International Education was designed and implemented as an avenue for teaching information literacy and to encourage use of library resources. The methodology for the assignment is presented, and the results of the project are discussed in terms of the final products and student reviews. Implications for the use of student-created LibGuides in academic institutions and future directions for this project are presented.     

A framework for gender justice: Evaluating the transformative capacities of three key Australian schooling initiatives

Through a feminist agenda that seeks to redress gender inequities through remedies of redistribution and recognition, this paper draws on Fraser’s work (1997) to articulate a framework of transformative justice. In moving beyond the competing logics underpinning such remedies, this framework adopts a transformative theory and politics in problematising and seeking to restructure the inequitable gender differentiation of political-economic structures and social patterns of representation, interpretation and communication. This framework of gender justice is presented as useful in evaluating the ideologies and practices of particular schooling initiatives and thus is drawn on to critically assess three initiatives that currently seek to address issues of social/gender equity in education within Australia: The New Basics Project, The Productive Pedagogies Framework and the Success for Boys initiative. In particular, the paper critically explores these initiatives in terms of their capacities for enabling or constraining a transformative redistributive and cultural gender justice.     

Information for trained nurses in remote areas: do electronically networked resources provide an answer?

This paper reports on a research project which examined the potential ofthe Internet, and other networked information resources, to improve access to information fortrained nurses working in remote areas. This paper provides a review of current literature in thefield. It describes the research carried out, presents a summary of the research findings anddiscusses the implications of these findings. The paper concludes that the Internet and networkedresources do have considerable potential to improve access to information for nurses working inremote and rural areas. However, information skills, along with professional guidance, are alsorequired.     

DNA capture-probe based separation of double-stranded polymerase chain reaction amplification products in poly(dimethylsiloxane) microfluidic channels

Herein, we describe the development of a novel primer system that allows for the capture of double-stranded polymerase chain reaction (PCR) amplification products onto a microfluidic channel without any preliminary purification stages. We show that specially designed PCR primers consisting of the main primer sequence and an additional “tag sequence” linked through a poly(ethylene glycol) molecule can be used to generate ds-PCR amplification products tailed with ss-oligonucleotides of two forensically relevant genes (amelogenin and human c-fms (macrophage colony-stimulating factor) proto-oncogene for the CSF-1 receptor (CSF1PO). Furthermore, with a view to enriching and eluting the ds-PCR products of amplification on a capillary electrophoretic-based microfluidic device we describe the capture of the target ds-PCR products onto poly(dimethylsiloxane) microchannels modified with ss-oligonucleotide capture probes.     

The BASES expert statement on exercise, immunity, and infection

An individual's level of physical activity influences their risk of infection, most likely by affecting immune function. Regular moderate exercise reduces the risk of infection compared with a sedentary lifestyle, but very prolonged bouts of exercise and periods of intensified training are associated with an increased risk of infection. There are several lifestyle, nutritional, and training strategies that can be adopted to limit the extent of exercise-induced immunodepression and minimize the risk of infection. This expert statement provides a background summarizing the evidence together with extensive conclusions and practical guidelines.
