Lenoir–Rhyne University is a co-educational, private liberal arts university founded in 1891 and located in Hickory, North Carolina, USA. The university is affiliated with the North Carolina Synod of the Evangelical Lutheran Church in America .In 2011–12 Lenoir–Rhyne enrolled approximately 1,980 students of whom 1,653 were undergraduate with a gender distribution of 35.4 percent male students and 64.6 percent female students. 55.0 percent of the students live in college-owned, -operated, or -affiliated housing and 45.0 percent of students live off campus. Dormitory visitation hours by the same or opposite sex is strictly regulated. Lenoir–Rhyne University participates in NCAA Division II athletics. Wikipedia.

This qualitative interpretive case study used Wenger’s (1998) communities of practice (CoP) framework to analyze how the electronic learning community (eLC) process at an established state virtual high school operated like a community of practice. Components of the eLC process were analyzed according to elements of the CoP framework, which provided a theoretical lens through which to analyze data gathered through interviews, observations, and document collection. Findings revealed several areas of alignment between the eLC process and the CoP framework, particularly with Wenger’s notion of practice within a CoP as a duality between participation and reification. © 2015, Taylor & Francis Group, LLC.

Toda (in SIAM J. Comput. 20(5):865-877, 1991) proved in 1989 that the (discrete) polynomial time hierarchy, PH, is contained in the class P#P, namely the class of languages that can be decided by a Turing machine in polynomial time given access to an oracle with the power to compute a function in the counting complexity class #P. This result, which illustrates the power of counting, is considered to be a seminal result in computational complexity theory. An analogous result in the complexity theory over the reals (in the sense of Blum-Shub-Smale real machines in Bull. Am. Math. Soc. (NS) 21(1): 1-46, 1989) has been missing so far. In this paper we formulate and prove a real analogue of Toda's theorem. Unlike Toda's proof in the discrete case, which relied on sophisticated combinatorial arguments, our proof is topological in nature. As a consequence of our techniques, we are also able to relate the computational hardness of two extremely well-studied problems in algorithmic semi-algebraic geometry: the problem of deciding sentences in the first-order theory of the reals with a constant number of quantifier alternations, and that of computing Betti numbers of semi-algebraic sets. We obtain a polynomial time reduction of the compact version of the first problem to the second. This latter result may be of independent interest to researchers in algorithmic semi-algebraic geometry. © 2010 SFoCM.

Validating a computational model is important as it establishes that the model has met its intended purpose of representing the system under study. In this paper, we perform a validation study on Construct, a multiagent network model for the coevolution of agents and the sociocultural environments that they inhabit. In particular, we focus on validating agent interactions produced by the model against empirical communication networks collected in real-world organizations. Validation is performed using our novel calibrated grounding technique. Results show that Construct can produce valid agent interactions. The benefits and implications of the study are discussed. © 2013 IEEE.

To better understand how birds balance the demands of reproduction and food-provisioning, Snowy Egrets (Egretta thula) were studied from May-July 2009 and 2010 in a mixed-species colony in Wichita, Kansas. Observations included 68 h of scan samples at 34 nests which yielded >11,000 instantaneous records; the durations of 57 food-provisioning trips made by eight radio-tagged birds; 73 records of foraging locations, and 27 h of foraging activity and aggressive intraspecific interactions. Adult activities at the nest included sitting (41% of the time), standing (18%), preening (10%), nest maintenance (7%) and feeding chicks (<1%). Incubating adults spent significantly more time sitting but less time standing than did adults with chicks. The amount of time that both parents were away from the nest increased significantly with chick age. Multiple regression analysis with AIC modeling showed that Julian date, chick stage, and year were important predictor variables in nest activity patterns. Mean food-provisioning intervals (242 ±22 min; range = 52-539 min) differed among radio-tagged birds, but did not differ by time of day or date. Round-trip flight distances averaged 16.1 ±3.2 km (range = 6-49 km), and also differed among birds. Distances to foraging sites were combined with published energetic values to estimate flight costs. Compared with birds that used distant foraging sites (>18 km from the colony), birds that used sites near the colony (<3 km) had higher capture efficiencies but caught smaller prey, had much higher rates of aggression, and lower rates of energy intake.

Background: Major depression is a significant yet underdiagnosed problem of adolescence. The consequences of undiagnosed and untreated depression in this vulnerable population can have detrimental effects. School nurses are in a prime position to perform early screening and referral. However, the school environment requires special consideration as the setting for screening of adolescent depression. Objective: The purpose of this paper is to identify instruments that can be utilized by the school nurse to performeasily administered, rapid adolescent depression screenings that are valid, reliable, and economical. Methods: An integrative review of current depression instruments used in adolescents was conducted. Results: Of the seven most commonly used instruments, only four of those fit the criteria listed for conducting screening in the school setting by the school nurse. The four instruments include the Beck Depression Inventory-Youth (BDI-Y), the Children's Depression Inventory, the Center for Epidemiological Studies-Depression Scale for Children, and the Reynolds Adolescent Depression Scale. Conclusion: Although all four of the identified instruments provide reliability and validity in the school setting, it is the other criteria: affordability, ease of administration, and the ability of the instrument to be rapidly scored, that placed the Center for Epidemiological Studies-Depression Scale for Children and the BDI-Y as the reasonable choice of instruments for use by the school nurse. © 2010 Wiley Periodicals, Inc.
