Letter processing and font information during reading: beyond distinctiveness, where vision meets design

Letter identification is a critical front end of the reading process. In general, conceptualizations of the identification process have emphasized arbitrary sets of distinctive features. However, a richer view of letter processing incorporates principles from the field of type design, including an emphasis on uniformities across letters within a font. The importance of uniformities is supported by a small body of research indicating that consistency of font increases letter identification efficiency. We review design concepts and the relevant literature, with the goal of stimulating further thinking about letter processing during reading

Effects of the high-density lipoprotein mimetic agent CER-001 on coronary atherosclerosis in patients with acute coronary syndromes: a randomized trial†

Aim High-density lipoproteins (HDLs) have several potentially protective vascular effects. Most clinical studies of therapies targeting HDL have failed to show benefits vs. placebo. Objective: To investigate the effects of an HDL-mimetic agent on atherosclerosis by intravascular ultrasonography (IVUS) and quantitative coronary angiography (QCA). Design and setting A prospective, double-blinded, randomized trial was conducted at 51 centres in the USA, the Netherlands, Canada, and France. Intravascular ultrasonography and QCA were performed to assess coronary atherosclerosis at baseline and 3 (2–5) weeks after the last study infusion. Patients Five hundred and seven patients were randomized; 417 and 461 had paired IVUS and QCA measurements, respectively. Intervention Patients were randomized to receive 6 weekly infusions of placebo, 3 mg/kg, 6 mg/kg, or 12 mg/kg CER-001. Main outcome measures The primary efficacy parameter was the nominal change in the total atheroma volume. Nominal changes in per cent atheroma volume on IVUS and coronary scores on QCA were also pre-specified endpoints. Results: The nominal change in the total atheroma volume (adjusted means) was −2.71, −3.13, −1.50, and −3.05 mm3 with placebo, CER-001 3 mg/kg, 6 mg/kg, and 12 mg/kg, respectively (primary analysis of 12 mg/kg vs. placebo: P = 0.81). There was also no difference among groups for the nominal change in per cent atheroma volume (0.02, −0.02, 0.01, and 0.19%; nominal P = 0.53 for 12 mg/kg vs. placebo). Change in the coronary artery score was −0.022, −0.036, −0.022, and −0.015 mm (nominal P = 0.25, 0.99, 0.55), and change in the cumulative coronary stenosis score was −0.51, 2.65, 0.71, and −0.77% (compared with placebo, nominal P = 0.85 for 12 mg/kg and nominal P = 0.01 for 3 mg/kg). The number of patients with major cardiovascular events was 10 (8.3%), 16 (13.3%), 17 (13.7%), and 12 (9.8%) in the four groups. Conclusion: CER-001 infusions did not reduce coronary atherosclerosis on IVUS and QCA when compared with placebo. Whether CER-001 administered in other regimens or to other populations could favourably affect atherosclerosis must await further study.

Predictors of Growth and Distress Following Childhood Parentification: A Retrospective Exploratory Study

Abstract While most of the existing literature has focused on the risks associated with parentification, we examined the potential benefits (i.e., posttraumatic growth) associated with parentification. Predictors of posttraumatic growth explored in our study included: attachment, differentiation of self, parentification, and resiliency. Partial support was found for the predictor variables leading to posttraumatic growth, with resilience emerging as the strongest predictor; resilience explained 14% of the variance in posttraumatic growth. These findings suggest that future research might explore additional resiliency factors that explain positive psychological outcomes related to childhood parentification

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44588/1/10802_2004_Article_222615.pd

Reflexiones de estudiantes universitarios, docentes de Agroecología (U.N.Cuyo) y agentes de extensión del INTA en prácticas de intervención socioproductivas en las zonas de Luján de Cuyo y Valle de Uco, Mendoza

En el marco de la asignatura Agroecología y Ambientes Rurales de la carrera en Ingeniería en Recursos Naturales Renovables (FCA- UNCuyo), se han realizado durante 10 años académicos consecutivos, dos actividades consistentes en visitar a diferentes tipos sociales agrarios ubicados en Luján de Cuyo y el Valle de Uco. En las nombradas actividades, los estudiantes realizan una visita extendida a productores que integran diferentes cadenas productivas, con el objetivo de caracterizar el ecosistema, sociosistema y tecnosistema en cada caso, además de diferenciar manejos convencionales y agroecológicos. Con la información recabada y reflexionada, los estudiantes realizan un trabajo integrador, con carácter de condición obligatoria para rendir el examen final de la asignatura, que rescata una problemática detectada y propone una solución socio tecnológica con base agroecológica, ajustada a las características de tipo social agrario abordado. El nombrado material queda a disposición de los actores involucrados para ser utilizado como una herramienta de comprensión de la dinámica socio-productiva y territorial. En el presente relato realizamos una breve síntesis sobre las experiencias de cada visita a campo y se presentan las reflexiones de los actores involucrados acerca de esta experiencia.In the framework of agroecology and rural environments race course in Engineering in Renewable Natural Resources (FCA UNCuyo) were performed for 10 consecutive school years, two consistent activities visit different agricultural social types are located in Lujan de Cuyo and Uco Valley.
