Is an integrative laboratory algorithm more effective in detecting alpha-1-antitrypsin deficiency in patients with premature chronic obstructive pulmonary disease than AAT concentration based screening approach?

Introduction:

Alpha-1-antitrypsin deficiency (AATD), genetic risk factor for premature chronic obstructive pulmonary disease (COPD), often remains undetected. The aim of our study was to analyse the effectiveness of an integrative laboratory algorithm for AATD detection in patients diagnosed with COPD by the age of 45 years, in comparison with the screening approach based on AAT concentration measurement alone.

Subjects and methods:

50 unrelated patients (28 males/22 females, age 52 (24–75 years) diagnosed with COPD before the age of 45 years were enrolled. Immunonephelometric assay for alpha-1-antitrypsin (AAT) and PCR-reverse hybridization for Z and S allele were first-line, and isoelectric focusing and DNA sequencing (ABI Prism BigDye) were reflex tests.

Results:

AATD associated genotypes were detected in 7 patients (5 ZZ, 1 ZM_malton, 1 ZQ0_amersfoort), 10 were heterozygous carriers (8 MZ and 2 MS genotypes) and 33 were without AATD (MM genotype). Carriers and patients without AATD had comparable AAT concentrations (P = 0.125). In majority of participants (48) first line tests were sufficient to analyze AATD presence. In two remaining cases reflex tests identified rare alleles, M_malton and Q0_amersfoort, the later one being reported for the first time in Serbian population. Detection rate did not differ between algorithm and screening both for AATD (P = 0.500) and carriers (P = 0.063).

Conclusion:

There is a high prevalence of AATD affected subjects and carriers in a group of patients with premature COPD. The use of integrative laboratory algorithm does not improve the effectiveness of AATD detection in comparison with the screening based on AAT concentration alone.     

Sliding manifold design for linear systems with unmatched disturbances

This paper offers an efficient sliding manifold design method that minimizes the impact of unmatched disturbances onto SM dynamics and system accuracy. System sensitivity upon unmatched constant or slowly varying external disturbance vector is evaluated by the steady-state dependent criterion function. An infinite set of sliding manifolds that minimize the chosen optimization criterion is determined and a way of selecting a manifold out of that set that provides adopted SM dynamics is suggested. The proposed approach has been demonstrated on numerical examples and verified by simulations.     

DIRECT OBSERVATIONS OF CHILDREN AT RISK FOR ACADEMIC FAILURE: BENEFITS OF AN INTERGENERATIONAL VISITING PROGRAM

Ten elementary school students in need of a positive self-image and/or a sense of appropriate social conduct took part in a monthly intergenerational visiting program at an assisted living facility. In comparison to systematic observations obtained in their classrooms, the children were observed to be significantly less anxious, more interested, and participating more during the intergenerational program. Outcomes of a focus group with five seniors revealed that they had enjoyed the program and wanted it to continue. School administrators may want to consider intergenerational visiting programs for students whose behaviors place them at risk for academic failure.     

The Pedagogy and Politics of Art in Postmodernity: Cognitive Mapping and The Bothersome Man

This essay inquires into the pedagogical and political dimensions of art in the contemporary moment. Specifically, it seeks to reanimate Fredric Jameson's notion of “cognitive mapping,” which he introduced as a response to the postmodern problem of representing the social totality. To that end, the essay begins by explicating the twin impulses of cognitive mapping. It, then, undertakes a sustained rhetorical analysis of Jens Lien's award-winning 2006 Norwegian film, The Bothersome Man, demonstrating how the film employs entropic satire to, at once, map and critique the cultural logic of late capitalism. The essay concludes by reflecting on the important contributions rhetorical scholars can make to a renewed interest in cognitive mapping.     

A conceptual framework for analysing the impact of influences on student engagement and learning

The notion that ‘customer satisfaction’ should be the ultimate measure of quality provision of any service organization is often accepted in the higher education context. However, measuring the quality of an educational institution based on students’ satisfaction is insufficient as it diverts the focus from student development, advancement and growth to an affective evaluation of the service. More appropriate measures of quality of higher education institutions are student engagement and learning. This study describes the likely impact of perceived overall quality of higher education institutions on student engagement. The contribution of this study is twofold. First, it draws attention to the importance of higher education institution quality as the main institutional-level determinant of student engagement and, second, it suggests a comprehensive multilevel conceptual framework for its empirical testing.     

Relationship between 2000-m rowing ergometer performance times and World Rowing Championships rankings in elite-standard rowers

Abstract

In this study, we evaluated the extent to which 2000-m rowing ergometer performance times predicted final rankings at the World Rowing Championships in a sample of 638 rowers of both sexes and body-mass classifications (i.e. open-category and lightweight rowers). Rowing ergometer performance times were examined using a questionnaire, and in 17 of 23 events they were positively correlated (P ≤ 0.049) with the final rankings at the Championships. The highest correlations were for the ergometer performance times achieved by rowers in lightweight men's single sculls (r = 0.78; P = 0.005), women's single sculls (r = 0.75; P = 0.002), men's single sculls (r = 0.72; P = 0.004), and lightweight men's double sculls (r = 0.72; P < 0.001). We used linear regression to establish regression equations to predict final rankings based on 2000-m rowing ergometer performance times for each event in which there was a correlation greater than r = 0.50. Although correlations in 12 events met this criterion, the large standard errors of the estimate hindered ranking predictions in all of the studied events. Regression equations could be used to determine the most probable 2000-m ergometer performance time for a rower to achieve specific rankings at the World Rowing Championships.     

Policy makers’ rhetoric of educational change: A critical analysis

Reforms in education often fail due to insufficient time to implement them, too few charismatic leaders, the influence of the preceding culture, scarce resources or an incapacity to comprehend the complexity of the education system. Most studies dealing with the cognitive aspects of educational change investigate the meaning of change through the lens of the educators and principals and there is not as much research available on the perception and interpretation of change by policy makers and the language they use to communicate messages about policy that affect sensemaking–sensegiving during the process of learning about the changes. Guided by the premise that the language of a reform movement is shaped by its ideology, this article illustrates how press releases of the Ministry of Education in Canton Sarajevo in Bosnia–Herzegovina reflect an exploitation-oriented dominant reform logic. The results of frequency analysis, hierarchical clustering and multidimensional scaling imply that MoE is driven by a top-down perspective to educational change, with a focus on the procedural, organizational and collaborational aspects of reforms that primarily alter the structure of the education system but not its internal substance. We end this paper by suggesting that educational system as complex adaptive system cannot be controlled, but effectively managed through distribution of control and creation of few attractors, benefiting from self-organization in the technical core and making change in the official top-down rhetoric.     

Hurdle preflight in springboard diving: a case of diminishing returns

Attempts to increase dive height by introducing a period of flight in the final approach step preceding the hurdle of dives from forward and reverse groups were investigated. One study involved 11 collegiate-level divers experienced in both traditional and hurdle preflight techniques. In a second study, dives executed by 9 national-level women were compared. Dives with a hurdle preflight had shorter final approach steps and greater hurdle flight durations. Flight time differences in favor of hurdle preflight techniques diminished from final approach step through hurdle flight to dive flight. Although the collegiate-level divers had longer dive flight times when using a hurdle preflight, it was suggested that the costs of these techniques may outweigh their potential benefits.
