Maintaining binding in working memory: Comparing the effects of intentional goals and incidental affordances

Much research on memory for binding depends on incidental measures. However, if encoding associations benefits from conscious attention, then incidental measures of binding memory might not yield a sufficient understanding of how binding is accomplished. Memory for letters and spatial locations was compared in three within-participants tasks, one in which binding was not afforded by stimulus presentation, one in which incidental binding was possible, and one in which binding was explicitly to be remembered. Some evidence for incidental binding was observed, but unique benefits of explicit binding instructions included preserved discrimination as set size increased and drastic reduction in false alarms to lures that included a new spatial location and an old letter. This suggests that substantial cognitive benefits, including enhanced memory for features themselves, might occur through intentional binding, and that incidental measures of binding might not reflect these advantages.

The Off-Season: Masculinities, Rurality, & Family Ties in Alaska Commercial Fishermen

The purpose of this study is to explore the intersections of masculinity, rurality, the family, and economics through the experiences of commercial fishermen in Alaska. Understanding masculinity as plural and the rural space as a sphere in which individuals operate, this study examines the relationship between the masculine rural and the rural masculine and how it pertains to commercial fishermen. I focus on the discourse already present about Alaska and commercial fishermen and combine this approach with notions of cultural and economic capital, as well as the local ecological knowledge (LEK). The fishermen describe their experiences in the industry as ones that are rooted in family influence and economic gain, while also believing that, in order to make money, a “true fisherman” needs to be able to learn fast and endure what the industry throws at them. This study adds to the body of knowledge already put forth about rural masculinities and offers a different approach to understanding a subculture that is rarely looked at today

A Lower Bound For Depths of Powers of Edge Ideals

Let $G$ be a graph and let $I$ be the edge ideal of $G$. Our main results in this article provide lower bounds for the depth of the first three powers of $I$ in terms of the diameter of $G$. More precisely, we show that \depth R/I^t \geq \left\lceil{\frac{d-4t+5}{3}} \right\rceil +p-1, where $d$ is the diameter of $G$, $p$ is the number of connected components of $G$ and $1 \leq t \leq 3$. For general powers of edge ideals we showComment: 21 pages, to appear in Journal of Algebraic Combinatoric

Understanding How Undergraduate Students Experience and Manage Stress: Implications for Teaching and Learning Anthropology

Research has shown that negative effects of stress on undergraduate students can have a significant impact on their college experience. Most of what we know about this topic is quantitative, based on surveys that provide self-reported information for large numbers of college students. The present study provides an in-depth qualitative perspective on college students and stress that foregrounds the voices of these emerging adults. Specifically, in this article we (a) share findings from a study using qualitative methods to examine how college students experience and manage stress and (b) provide strategies to help anthropology instructors design and manage their classes to improve learning for students under chronic stress

Exertional sickling: Questions and controversy

Sickle cell trait (SCT) occurs in about 8% of African-Americans and is often described to be of little clinical consequence. Over time, a number of risks have emerged, and among these are rare but catastrophic episodes of sudden death in athletes and other individuals associated with physical activities which is often described as exercise collapse associated with sickle trait (ECAST). Despite an epidemiologic link between SCT and sudden death as well as numerous case reports in both medical literature and lay press, no clear understanding of the key pathophysiologic events has been identified. Strategies for identification of individuals at risk and prevention of ECAST have been both elusive and controversial. Stakeholders have advocated for different approaches to this issue particularly with regard to screening for hemoglobin S. Furthermore, the recommendations and guidelines that are in place for the early recognition of ECAST and the prevention and treatment of the illness are not well defined and remain fragmented. Among the cases identified, those in collegiate football players in the United States are often highlighted. This manuscript examines these case studies and the current recommendations to identify areas of consensus and controversy regarding recommendations for prevention, recognition and treatment of ECAST

The Off Season: Masculinities, Rurality, and Family Ties in Alaska Commercial Fishing

This study explores the intersections of masculinity, rurality, the family, and ecology through the experiences of commercial fishermen in Alaska. By understanding the plurality of masculinities and how men operate within a rural space, this study investigates the relationship between the masculine rural and the rural masculine and how that relationship pertains to commercial fishermen. This study examines existing discourse about Alaska and the masculinity of commercial fishermen in light of the concepts of cultural and economic capital, as well as local ecological knowledge (LEK). It further examines how fishermen describe their experiences in the industry as ones that are rooted in family influence and economic gain, while also believing that in order to make money, a “true fisherman” needs to be able to learn fast and endure what the industry throws at them. By exploring these parallels, this study reveals that Alaska commercial fishermen shape their gender identities on the notion that only a “true fisherman” is capable of achieving success through hard work, family support, and the utilization of local knowledge

First Collection Records of \u3ci\u3eHippodamia Variegata\u3c/i\u3e (Coleoptera: Coccinellidae) in Minnesota Corn and Soybean

The coccinellid Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is a relatively recent addition to the North American coccinellid fauna. This species was first reported in 1984 near Montreal, Quebec (Gordon 1987). Since then, its range has expanded beyond northeastern North America with the newest records in the midwestern United States, including Michigan (Gardiner and Parson 2005), Ohio (Pavuk et al. 2007), Wisconsin (Williams and Young 2009), and most recently South Dakota (Hesler and Lundgren 2011). Here we provide the first records of H. variegata in Minnesota. In addition, our records further define the movement pattern of this beetle across the Midwest by documenting its presence in the gap between Wisconsin and South Dakota
