Driving Along the Zinc Road.

Editorial introductions

Current Opinion in Allergy and Clinical Immunology was launched in 2001. It is one of a successful series of review journals whose unique format is designed to provide a systematic and critical assessment of the literature as presented in the many primary journals. The fields of allergy and clinical immunology are divided into 14 sections that are reviewed once a year. Each section is assigned a Section Editor, a leading authority in the area, who identifies the most important topics at that time. Here we are pleased to introduce the Journal's Editors and Section Editors for this issue.

Doctoral education has been the primary conduit for social workers to develop research skills and is an important component in achieving a long-term research-based career genson, Briar-Lawson, & Flanzer, 2008). In social work, doctoral training affords students opportunities to identify and study meaningful substantive topics and acquire advanced methodological and analytical skills (Jenson et al., 2008). This preparation alone, however, may not be a sufficient foundation for all social workers to build a successful research career. Postdoctoral research training can help social workers strengthen their research skills and build a collaborative research agenda. Although postdoctoral training for social workers is not a new phenomenon, it is a pathway for social work research training that has not gained the momentum it has in other social science fields (for example, psychology). The limited experience with formal postdoctoral training within the field of social work may create challenges for students interested in postdoctoral research positions and the faculty members who are mentoring such students. Further, unfamiliarity with postdoctoral training presents challenges for graduates who pursue these positions as they may not fully understand their role, the role of postdoctoral mentors, and the opportunities available to them as trainees. Although career development articles exist for students considering postdoctoral training in a variety of fields (for example, Committee on Science, Engineering, and Public Policy [COSEPUP], 2000; DeMets et al., 2006; Gennaro, Deatrick, Dobal, Jemmott, & Ball, 2007; Khalsa & Pearson, 2007), the linfited number of articles related to postdoctoral training for social workers have focused on individual experiences (for example, Fenster, 2006) and specific funding mechanisms (for example, Matthieu, Bellamy, Pena, & Scott, 2008). To help fill this gap in the social work literature, this article provides an overview of postdoctoral research training opportunities for a variety of substantive areas and describes the potential benefits of postdoctoral training. In addition, this article highlights some potential drawbacks that should be considered when deciding whether to complete a postdoctoral research position. This practical advice may be particularly helpful for students or junior scholars considering postdoctoral research training and doctoral faculty members who supervise students considering such training. POSTDOCTORAL TRAINING Although postdoctoral training has been a traditional step in the education process for the physical sciences, it has not played a similar role in the career of most social work scholars. As many fields grow more complex, the difficulty of familiarizing one's self with interesting and relevant material has increased, at least within the time limits of traditional graduate programs (COSEPUP, 2000; DeMets et al., 2006). Postdoctoral training is one way to balance the need to train students in new and evolving methodologies and ensure that they receive training in the basic core of theory, methods, and their substantive areas. Irrespective of discipline, the primary purpose of postdoctoral training is to expand research skills and grow intellectually (O'Mara & Bakos, 2003). Postdoctoral positions can help recent graduates expand their collaborative research base and develop independent research programs (COSEPUP, 2000; DeMets et al., 2006). Postdoctoral training also provides opportunities for early career researchers to interact intensively with senior investigators and establish collaborations with other junior researchers. In certain settings, this type of training can help promote interdisciplinary research that brings together different disciplines and combines their respective theoretical and methodological approaches. POSTDOCTORAL TRAINING FOR SOCIAL WORKERS Research capacity at the postgraduate level has been a relatively neglected part of the social work research training continuum (Fraser, Jenson, & Lewis, 1993; National Association of Deans and Directors Task Force, 1997). …

Studies of till deposition and fabric measurements from modern glacial deposits are important for studying the genesis of Pleistocene and pre-Pleistocene glacial sediment.Basal till at Burroughs Glacier is deposited at the ice margin by the melting of basal debris-rich ice that stagnated progressively, from the bottom upward, beneath moving ice during deglaciation. The debris-rich ice is typically ∼1-3 m thick and has very high sediment content ranging from 60% to 70% by volume. The long axes of pebbles in the debris-rich ice, and in other parts of the basal transport zone of the glacier, are typically well oriented parallel to ice flow. The average S1 eigenvalue for nine fabrics measured in the basal transport zone is 0.8092 ± 0.067σ. The basal till is massive, matrix-supported, silty-sandy diamicton. Striated, lodged boulders, and crag and tails are common on the till surface. S1 eigenvalues calculated from 27 pebble fabrics measured in the till range from 0.4930 (no fabric) to 0.8261; the average value is 0.6757 ± 0.092σ. The range of values is nearly identical to that reported for fabrics from "undeformed lodgment till" by Dowdeswell and Sharp (1986).Although the final process of till deposition at Burroughs Glacier is passive melt out from stagnant, debris-rich ice, the nature and pebble fabric of the till are inherited from active ice processes, specifically the progressive stagnation of debris-rich ice beneath active ice. Evidence of differential movement (shear) within the debris-rich ice during deposition is reflected in a change in fabric azimuth with depth in the till, beveled bullet boulders, and shear surfaces. These features are typically thought to be characteristic of lodgment till or brittle deformation of subglacial sediment. The melt-out process is passive because of the very high debris content of the debris-rich ice. If the same sequence of till deposition occurred in older glacial deposits and the debris content of the basal ice was high, the final process of melt-out would not be reflected in properties of the sediment.

The samples were subjected to progressive thermal demagnetization from 600 to 700 °C and analyzed by using principal-components analysis. A high-temperature component was isolated with a mean direction of declination = 351.7°, inclination = -28.4°, and α95 = 6.7°, and a corresponding paleopole at long 113.5°E, lat 33.7°N. Three normal and three reversed polarity magnetozones were defined, and it was found that the magnetic field was ∼59% normal and 41% reversed in the upper Chesterian. Herein we attempt to correlate the section to a previous study in New Brunswick on the basis of the paleolatitude (pole position) and the reversal pattern, and we postulate a correlation of the bottom part of the Maringouin section with the top off the Mauch Chunk. Such a correlation would place the Mississippian/Pennsylvanian boundary within the Maringouin Formation. Earth's magnetic field was of normal polarity at the time of the Mississippian/Pennsylvanian boundary. This content is PDF only. Please click on the PDF icon to access.
