Asthma is a chronic disease of the airways. It affects approximately 12% of American children, and it appears that that incidence is increasing. Asthma in children negatively influences school‐based outcomes such as absenteeism and friendship formation. Potential triggers of asthma include environmental allergens, exercise, weather, and emotional states. These lead to airway swelling and muscle constriction, which ultimately block airflow and impede breathing. In addition to medical treatments, the implementation of psychologically based interventions has been efficacious in school settings. © 2007 Wiley Periodicals, Inc.  相似文献

Let X=x1,x2,…,xnX=x1,x2,,xn be a sequence of non-decreasing integer values. Storing a compressed representation of X that supports access and search is a problem that occurs in many domains. The most common solution to this problem uses a linear list and encodes the differences between consecutive values with encodings that favor small numbers. This solution includes additional information (i.e. samples) to support efficient searching on the encoded values. We introduce a completely different alternative that achieves compression by encoding the differences in a search tree. Our proposal has many applications, such as the representation of posting lists, geographic data, sparse bitmaps, and compressed suffix arrays, to name just a few. The structure is practical and we provide an experimental evaluation to show that it is competitive with the existing techniques.  相似文献

This is discussion of one of Leo Tolstoy’s fictional dramatisations of aggressive but dull-witted pedagogy. In Anna Karenina, two adults badger a lively, deep-souled, active-minded boy, Anna’s son Seryozha, to learn his rote-lessons.  相似文献

This paper reprises the argument for the emergence of a global education policy field and then focuses on the shared habitus of global and national policy actors and technicians. It is argued that this shared habitus is constituted as a reflection of and a contribution to the creation of the global education policy field. Bourdieu’s approach to habitus as both methodological tool and concept is used and the significance of the interview encounter to understanding habitus is argued. The authors also draw on the content of interviews with five elite policy-makers and technicians. It was found that the policy actors and technicians shared a similar middle-class embodied habitus; in terms of schemes of perception, they identified with a high-modernist confidence in both science and technology; they identified with a cosmopolitan outlook and sensibility; and demonstrated scientistic approaches that held real confidence in understanding the social through quantitative social science methods.  相似文献

In this article the author, a certified performance technologist (CPT), explains what led him to pursue the CPT designation and what he has learned since then. His learning journey is framed by the three phases of Shu‐Ha‐Ri, a martial arts concept. He tells of how he developed a foundational proficiency with the CPT performance standards before truly understanding the principles and foundational concepts behind the practices associated with the standards. In his early days, he studied the work of performance improvement masters and practiced their techniques, both interpersonal and analytical. In the years after earning the CPT designation, he strove for true mastery in applying hybrid techniques or ones of his own invention, all grounded in the CPT principles.  相似文献

The purpose of this study was to explore academic and social integration and other outcomes for community college transfer students. The study used Tinto’s (Leaving college: Rethinking the causes and cures of student attrition, 1993) Longitudinal Model of Institutional Departure and Deil-Amen’s (J Higher Educ, 82:54–91, 2011) concept of “socio-academic integrative moments” to inform the selection and organization of potential predictors. We developed regression models for relationships between demographic and background variables of interest and perceived academic and social integration following the first six weeks at the receiving university. We also included these perceived integration scores in regression models for six outcomes (first and second semester grade point average, first and second semester earned hours ratios, and second and third semester persistence). Academic and previous college background explained the greatest amount of variance in predicting early integration and academic outcomes.  相似文献
