The problems of undertaking interdisciplinary research, particularly in the fields of history and archaeology are considered. A series of five issues are identified which make it difficult to integrate studies from these two areas: knowledge mismatch, a mismatch of chronologies, an inability to match types of information, problems of the scale of study and issues around the maturity of the disciplines. Each discipline tends to enforce the particularities of its own vision, training students to its perspective and perpetuating the differences. Interdisciplinary is not, however, a doomed pursuit, and is likely to be most successful when there are clear and immediate benefits for all the parties.

The comparison of scanning transmission electron microscopy (STEM) with conventional transmission electron microscopy (CTEM) can best be made by means of the Reciprocity Theorem of wave optics. In Fig. 1 the intensity measured at a point A’ in the CTEM image due to emission from a point B’ in the electron source is equated to the intensity at a point of the detector, B, due to emission from a point A In the source In the STEM. On this basis it can be demonstrated that contrast effects In the two types of instrument will be similar. The reciprocity relationship can be carried further to include the Instrument design and experimental procedures required to obtain particular types of information. For any. mode of operation providing particular information with one type of microscope, the analagous type of operation giving the same information can be postulated for the other type of microscope. Then the choice between the two types of instrument depends on the practical convenience for obtaining the required Information.

Abstract P-type ATPases transport ions across biological membranes against concentration gradients and are essential for all cells. They use the energy from ATP hydrolysis to propel large intramolecular movements, which drive vectorial transport of ions. Tight coordination of the motions of the pump is required to couple the two spatially distant processes of ion binding and ATP hydrolysis. Here, we review our current understanding of the structural dynamics of P-type ATPases, focusing primarily on Ca2+ pumps. We integrate different types of information that report on structural dynamics, primarily time-resolved fluorescence experiments including single-molecule Förster resonance energy transfer and molecular dynamics simulations, and interpret them in the framework provided by the numerous crystal structures of sarco/endoplasmic reticulum Ca2+-ATPase. We discuss the challenges in characterizing the dynamics of membrane pumps, and the likely impact of new technologies on the field.

Purpose This study examined caregiver perceptions of their child's language and literacy disorder as influenced by communications with their speech-language pathologist. Method The participants were 12 caregivers of 10 school-aged children with language and literacy disorders. Employing qualitative methods, a collective case study approach was utilized in which the caregiver(s) of each child represented one case. The data came from semistructured interviews, codes emerged directly from the caregivers' responses during the interviews, and multiple coding passes using ATLAS.ti software were made until themes were evident. These themes were then further validated by conducting clinical file reviews and follow-up interviews with the caregivers. Results Caregivers' comments focused on the types of information received or not received, as well as the clarity of the information. This included information regarding their child's diagnosis, the long-term consequences of their child's disorder, and the connection between language and reading. Although caregivers were adept at describing their child's difficulties and therapy goals/objectives, their comments indicated that they struggled to understand their child's disorder in a way that was meaningful to them and their child. Conclusions The findings showed the value caregivers place on receiving clear and timely diagnostic information, as well as the complexity associated with caregivers' understanding of language and literacy disorders. The findings are discussed in terms of changes that could be made in clinical practice to better support children with language and literacy disorders and their families.

Abstract. Background: Suicide is a pervasive and complex issue that can challenge counselors through the course of their careers. Research and practice focus heavily on crisis management and imminent risk rather than early intervention strategies. Early intervention strategies can assist counselors working with clients who have suicidal ideation, but are not at imminent risk, or with clients whose risk factors identify them as having a stronger trajectory for suicidal ideation. Aims: This systematic literature review examines the current literature on working with clients with suicidal ideation who are not at imminent risk, to ascertain the types of information and strategies available to counselors working with this client group. Method: An initial 622 articles were identified for analysis and from these 24 were included in the final review, which was synthesized using a narrative approach. Results: Results indicate that research into early intervention strategies is extremely limited. Conclusion: It was possible to describe emergent themes and practice guidelines to assist counselors working with clients with suicidal ideation but not at imminent risk.
