Optic nerve crescents and refractive error.

Abstract: In this paper we discuss whether the presence of an optic nerve crescent might affect the way in which axial length and corneal curvature interact to determine refractive error. Subjective refraction, keratometry, measurement of body height, axial length of the eye, and stereophotography of the optic nerves were performed on 224 subjects, 8- to 25-years-old. Photographs were examined under magnification; optic nerve crescents, if present, were measured in the horizontal dimension. Those measurements were then corrected for magnification due to the eye and the camera. Logistic regression analysis suggested that male gender and myopic refractive error were most directly associated with the presence of a large crescent, whereas axial length, age, and horizontal keratometry reading were less directly associated with the presence of a crescent. The relation between axial length and refractive error differed among those with large crescents compared to those with small or no crescents. Simple regression showed that, for those with a crescent at least 0.2-mm wide, a 1-mm greater axial length was associated with, on the average, 1.26 D of myopia. For those with smaller or no crescents, a 1-mm greater axial length was associated with only 0.66 D of myopia. This difference was statistically significant at the 0.02 level of confidence.

Media Literacy and Information Literacy: A Need for Collaboration and Communication

Abstract: Both media literacy and information literacy struggle for legitimacy in school curricula, and seek to be recognized as relevant to student learning initiatives. While each has a distinct historical context, a dedicated group of followers, and base of research and intervention, neither has alone achieved the scale needed to make systemic change in public education in the United States. The author proposes recognition of the strengths of each, a combined effort of supporters, and a dedication to the new approaches and initiatives working to make changes in education that could have a lasting effect on the ways students use, learn, and understand media in their educational and personal lives.

Maternal cradling bias and early communicative interactions: Implications for early identification of children at risk

Abstract: Nurturing mothers cradle their babies during the first months of life while feeding, talking to them, calming and/or rocking them to sleep. In the late 1970’s, several researchers began to observe a behavior during this interaction. This behavior appeared to be an unconscious positioning of newborns by their mother to the mother’s left arm during “cradling” (Bundy, 1979; Ginsburg, Fling, Hope, Musgrove, & Andrews, 1979). Other researchers confirmed in later studies that cradling bias to the left side was observed when mothers cradled their newborns (Bourne & Todd, 2004; Donnot, 2007; Hopkins, 2004; Matheson & Turnbull, 1998; Reissland, 2000; Reissland, Hopkins, Helms, & Williams, 2009; Sieratzki, Roy, & Woll, 2002; Sieratzki & Woll, 2002, 2004; Tomaszycki, Cline, Griffin, Maestripieri, & Hopkins, 1997; Turnbull & Bryson, 2001; Turnbull & Lucas, 1990, 1996; Turnbull, Rhys-Jones, & Jackson, 2001; Vauclair & Donnot, 2005; Woll & Sieratzki, 2002). The incidence of left side cradling bias has been shown to be around 70% to 80% regardless of culture (Bourne & Todd, 2004) or handedness of the mother (van der Meer & Husby, 2006; Previc, 1991; Sieratzki & Woll, 1996, 2002; Vauclair & Donnot, 2005). Investigations into the reason(s) why this particular positioning occurs have included studies on correlations between several known human traits and innate biases. For example, it was thought that maternal left ear/right hemisphere advantage for the perception and processing of prosodic speech (Sieratzki et al., 2002) or more specifically the maternal hemispheric specialization of emotion processing and social/communicative behaviors (Sieratzki & Woll, 2002; Turnbull & Bryson, 2001) would answer the question regarding why cradling bias to the left occurs; however, has not been empirically proven. Hemispheric asymmetry of maternal attentional systems (Turnbull & Lucas, 1996), handedness (van der Meer & Husby, 2006; Previc, 1991; Sieratzki & Woll, 1996, 2002; Vauclair & Donnot, 2005), (Sieratzki & Woll, 2002), maternal hemispheric arousal and attention (Harris, Almerigi, Carbary, & Fogel, 2001), maternal stress (Bourne & Todd, 2004; Reissland et al., 2009; Sieratzki & Woll, 2002), pitch of maternal voice in child directed language (Reissland, 2000), maternal affect (Legerstee, Markova, & Fisher, 2007), infant positional bias (Hopkins, 2004), and infant nipple preferences during breastfeeding (Tomaszycki et al., 1997), have been the

Nailing down a future for a small wood‐products business

Abstract: Liberty Industries was founded in 1964 by its current President and Chairman of the Board, Charles E. Trebilcock. It began as a small industrial wholesale lumber firm located in northeastern Ohio, specializing in wood packaging products. The original plan called for a regionalized concentration of sales in a four‐ to five‐state area. Liberty experienced moderate growth during its first nine years, when it functioned as a three‐person organization. In 1973, the firm decided to increase field sales by developing an inside support department. A marketing manager was hired, as well as several product specialists. As a result, sales increased more than 13 times from 1972 through 1979. (See Exhibit 1.)

A Compact Ciphertext-Policy Attribute-Based Encryption Scheme for the Information-Centric Internet of Things

Abstract: The information-centric Internet of things (IC-IoT) is different from the traditional Internet of things (IoT) in that the device-to-device pattern is generalized to a device-to-network pattern. Furthermore, in an IC-IoT environment, there is a demand for protecting the security of all data generated from IC-IoT devices. A cryptography scheme named attribute-based encryption (ABE) represents a smart method of providing the fine-grained access control that can sufficiently protect data security. The most attractive advantage of ABE is its expressive access policy, which makes the access control of data flexible and manageable. However, there is a serious problem caused by such an access policy; it incurs a greater ciphertext redundancy and computational overhead. This implies that the current ABE scheme is hard to implement in the thin client devices of IC-IoT. In this paper, we propose a universalized policy-compacting method via sharing public parts of the policy. Compared with the original policy, the compacted policy applies a more compact ciphertext and requires less computation, communication, and storage cost. However, the policy-compacting problem is proved to be a non-deterministic polynomial complete (NPC) problem. Thus, a greedy algorithm is provided to obtain an approximate minimum compacted policy scale. Finally, we propose a compact ciphertext-policy attribute-based encryption (CCP-ABE) scheme with the policy-compacting method. A security proof and performance evaluation show that the proposed CCP-ABE scheme provides a comprehensive performance improvement.
