Power and sample size determination for group comparison of patient‐reported outcomes using polytomous Rasch models

Field: Psychology (Social Sciences)

The analysis of patient‐reported outcomes or other psychological traits can be realized using the Rasch measurement model. When the objective of a study is to compare groups of individuals, it is important, before the study, to define a sample size such that the group comparison test will attain a given power. The Raschpower procedure (RP) allows doing so with dichotomous items. The RP is extended to polytomous items. Several computational issues were identified, and adaptations have been proposed. The performance of this new version of RP is assessed using simulations. This adaptation of RP allows obtaining a good estimate of the expected power of a test to compare groups of patients in a large number of practical situations. A Stata module, as well as its implementation online, is proposed to perform the RP. Two versions of the RP for polytomous items are proposed (deterministic and stochastic versions). These two versions produce similar results in all of the tested cases. We recommend the use of the deterministic version, when the measure is obtained using small questionnaires or items with a few number of response categories, and the stochastic version elsewhere, so as to optimize computing time.

A Technique for Rearing the Limabean Pod Borer, Etiella zinckenella TREITSHKE (Lepidoptera : Pyralidae) in Large Scale

Field: Agricultural and Biological Sciences (Life Sciences)

Rearing of the limabean pod borer, Etiella zinckenella, in large scale has been practically impossible without a technique to reduce cannibalism. This problem was resolved by isolating larvae on a diet with a multicellular unit. The rearing procedure is as follows : Newly hatched larvae were placed on the roughened surface of diet in each cell of the unit. The top of the multicellular unit was covered with rough papers and pressed with a magazine. The tray was then closed with a lid, its windows covered with net, and placed in darkness for three days. Afterwards, it was transferred to a constant temperature cabinet at 25°C under a 16-photoperiod. Ten days after trhe larval infestation, the magazine was removed. During the period from 12 to 16 days after infestation, the mature larvae were transferred daily to a plastic pot (9.5 cm diam.) with nonabsorbent cotton. After 20 days, pupae were collected from the cotton. By this xethod, 51.5% of the larvae introduced into the tray were recovered as moths. Eggs were collected by providing the cage in which the moths were released with a soybean twig covered with cheesecloth as an oviposition site.
Unified Optimization of Traffic Flows Through Airports

Field: Decision Sciences (Social Sciences)

We present a novel integer optimization approach to optimize, in a tractable and unified manner, the airport operations optimization problem. This includes solving the entirety of key air traffic flow management problems faced at an airport: (a) selecting a runway configuration sequence, i.e., determining which runways are open at which times and in which mode they operate; (b) assigning flights to runways and determining the sequence in which flights are processed (i.e., when they take off or land); (c) determining the gate-holding duration of departures; and (d) routing flights to their assigned runway and onward within the terminal area and the near-terminal airspace. The key contribution of this paper is the modeling of these problems, which until present have been studied in isolation, under a framework that is both unified and tractable. This allows the possibility of obtaining system-optimal solutions in a practical amount of time. Furthermore, the approach is implemented on historic data sets from both Boston Logan International and Dallas/Fort Worth International airports. Computational experience indicates that significant reductions in delays, fuel use, and emissions can be achieved from this optimization and that computational tractability is such that real-world instances can be solved within five to 10 minutes.

Probing professional identities of English Language Teacher Educators through collaborative study groups: Insights from a teacher educator team in Colombia

Field: Social Sciences (Social Sciences)

Monolithic views of language that privilege standard varieties of English, as well as technical and instrumental understandings of English teacher responsibilities have been increasingly critiqued by researchers interested in critical English teacher education and the promotion of Teaching English as an International Language (TEIL). A more holistic approach to teacher education, has been advocated instead, one that takes into consideration critical identity constructions and negotiations as part of English teacher education. An area of research that is often overlooked is that of English Language Teacher Educators (ELTEs), and their engagement with their own identities as ELTEs in a given context, which is of particular salience in post-colonial contexts. Thus, this study had the aim to examine how professional identities of ELTEs might evolve considering current socio-political factors surrounding TEIL in Colombia. Framed by an interpretive paradigm and a critical action research approach, this in-depth study explores how a group of 5 ELTEs have constructed and transformed their identity in a Colombian English Teacher Education institution. The study was focused on their ability to critically reflect on their identities by means of collaborative learning through small study groups, of which the author was a member. Three data collection methods were used: interviews to explore current ELTEs’ identities; 5 small-group study events as a method to raise awareness of tensions around EIL; and ELTEs’ reflective accounts to access the effect of the group experience in their identity construction. The main findings of this investigation showed some degree of change in ELTEs’ professional identities in relation to the use of English as an International Language (EIL), namely becoming more critical towards the politics of English and its implications at local and global levels, ELTEs’ emotional dimension showed paramount importance in the construction of their professional identities. Illustrating the on-going impact of this study design, participant ELTEs found new development and alternative research options in their own professional practices, such as using collaborative learning groups for their own professional development in their undergraduate language teacher programme at their institution. This indicates that a shift in ELTEs’ conception of English can trigger other changes in their political stance as well as their professional identities and practices. The findings of this study might be useful for ELTEs, language teacher programmes, and other educational stakeholders who oversee the policies of foreign languages (English) in Colombia and other (post-colonial) regions.
Copper diffusion barrier properties of CVD boron carbo-nitride

Field: Materials Science (Physical Sciences)

The copper diffusion barrier properties of amorphous boron carbo-nitride (BCxNy) films were studied. The BCxNy films were deposited by chemical vapor deposition at 360°C and 1Torr using dimethylamine borane with no reaction gas (BC0.37N0.15), with NH3(BC0.19N0.44), or with C2H4(BC0.90N0.08); their dielectric constants were 4.1, 4.4, and 3.9, respectively. A SiC0.76N0.44 film was used to benchmark the study. Barrier films were deposited on 7nm thermal oxide∕n-type Si substrates. The leakage current for BC0.90N0.08, 1.1×10−8A∕cm2 at 0.5MV∕cm, is the lowest of the three but it is larger than that of the benchmark SiC0.76N0.44 film, 5.5×10−9A∕cm2. Time dependent dielectric breakdown is used to test barrier time-to-failure of Cu-gate capacitors at 150°C and +2to5MV∕cm. BC0.90N0.80 displayed barrier performance comparable to SiC0.76N0.44 and was noticeably better than BC0.37N0.15 and BC0.19N0.44. Overall, BCxNy barriers are promising and are improved with lower boron content, fewer B–B bonds, and increased B–C bonds.

Field: Social Sciences (Social Sciences)

The objectives of this study were to explore in-service teachers’ views of the nature of science and process skills (NOS and PS), compare teachers’ views of NOS and PS in terms of some selected demographic variables such as gender, work experience, grade levels, and subjects they teach. In addition, measure the effect of these demographic variables on teachers’ views of NOS and PS. Cross-sectional descriptive survey employed. Convenience and purposive samplings used to select study subjects. Data collected by using VNOS- form D that modified by Ling et als in 2006. Frequency count, Kruskal Wallis Test, two-ways ANOVA, and multiple regressions used to analyze data. The findings indicated, in-service teachers had naïve views in nine or 39.1% questions out of 23 questions about NOS and PS. In comparing groups, there are significant difference in gender, work experience, and grade level they teach. From effect analysis, gender and work experience had significant effect on views of NOS. There is no significant interaction effect of all paired variables. The regression indicates, demographic characteristics had significant contributions on views of NOS and PS (F (4, 222) = 4.78, p = .001). Generally, the findings indicated, there is effect of demographic variables on teachers’ views of NOS, though it is small. Thus, when developing school curricula, integrating concepts related to NOS suggested in different level. In addition, when developing college curricula for in-service teachers, the effect of demographic characteristics on their views NOS and PS needs consideration. Therefore, may college and school curricula revision in terms of NOS. In addition, seminars, mentoring, and reflective readings suggested to minimize problems related to in-service teachers’ views of NOS and PS.

Development of Analysis Tools for Heat Pipes Used in Small Modular Reactors: Sodium Property Correlations

Field: Energy (Physical Sciences)

Abstract Advanced small modular reactors strive to improve reactor safety through increased utilization of passive heat transport and safety systems. An innovative means of meeting this design goal is to use alkali metal heat pipes to cool the reactor under both normal and abnormal operating conditions. A heat pipe model has been added to the ARIANT thermalhydraulic code to enable reactor modeling and support the design and licensing of new reactors. Saturation fluid properties are a fundamental input to this model. Consequently, this article provides a comprehensive comparative overview of the best available sodium saturation property correlations developed over the past century. The results show most of the sodium property correlations needed to model a heat pipe are relatively well-defined and recommendations for their use can be provided.
Robotic agricultural instrument for automated extraction of nematode cysts and eggs from soil to improve integrated pest management

Field: Agricultural and Biological Sciences (Life Sciences)

Soybeans are an important crop for global food security. Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count them. Extraction is typically conducted in commercial soil analysis laboratories and university plant diagnostic clinics and involves repeated steps of sieving, washing, collecting, grinding, and cleaning. Here we present a robotic instrument to reproduce and automate the functions of the conventional methods to extract nematode cysts from soil and subsequently extract eggs from the recovered nematode cysts. We incorporated mechanisms to actuate the stage system, manipulate positions of individual sieves using the gripper, recover cysts and cyst-sized objects from soil suspended in water, and grind the cysts to release their eggs. All system functions are controlled and operated by a touchscreen interface software. The performance of the robotic instrument is evaluated using soil samples infested with SCN from two farms at different locations and results were comparable to the conventional technique. Our new technology brings the benefits of automation to SCN soil diagnostics, a step towards long-term integrated pest management of this serious soybean pest.

The Anti-ulcerogenic Effect of an Alkaloidal Fraction from Mikania cordata on Diclofenac Sodium-induced Gastrointestinal Lesions in Rats

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Abstract A decoction of Mikania cordata (Compositae) is commonly used for the treatment of gastric ulcer in the Rajbari district of Bangladesh. We have evaluated the anti-ulcerogenic effect of the alkaloidal fraction from the whole plant of M. cordata on diclofenac sodium-induced gastrointestinal lesion in rats. Long Evan's rats were divided into five groups. The control group was kept undisturbed. The vehicle group received vehicle after a 48-h fast. The diclofenac group received diclofenac sodium suspension (80mgkg−1) after a 48-h fast. The diclofenac-ranitidine group (anti-ulcer drug used as a standard) received 35 mgkg−1 ranitidine hydrochloride suspension 1 h after diclofenac sodium administration, after a 48-h fast. The diclofenac-extract group received alkaloidal fraction (50 mgkg−1) 1 h after diclofenac administration, after a 48-h fast. The biochemical, morphological and histological changes were studied. The data showed that the pH values of the stomach and duodenum were increased significantly (P &lt; 0.001) in the alkaloidal-administered group compared with the control group (3.09 ± 0.0429 vs 2.07 ± 0.0339 and 6.79 ± 0.1162 vs 6.19 ± 0.1273, respectively). There were significant changes (P &lt; 0.001) detected in the morphological study. The ulcer index of the stomach (0.268 ± 0.0346) and of the duodenum (0.050 ± 0.0129) in the alkaloidal-administered group were significantly lower than the diclofenac-only administered group (0.691 ± 0.0184 and 0.093 ± 0.0138, respectively). According to the grading of tissue damage in the histological study, there were less or no lesions on the gastrointestinal mucosa of the alkaloidal-administered group compared with the diclofenac-only group (0 vs 5, respectively). When the results of the alkaloid extract group where compared with the ranitidine hydrochloride group a similar or more potent effect was observed with the alkaloidal extract group. The results of this study revealed that the bioactive principles of M. cordata have anti-ulcerogenic effects. The results validate the traditional use of this plant for the treatment of gastric ulcer in Bangladesh.

Screening for Inhibitors of Main Protease in SARS-CoV-2: In Silico and In Vitro Approach Avoiding Peptidyl Secondary Amides

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

In addition to vaccines, antiviral drugs are essential for suppressing COVID-19. Although several inhibitor candidates were reported for SARS-CoV-2 main protease, most are highly polar peptidomimetics with poor oral bioavailability and cell membrane permeability. Here, we conducted structure-based virtual screening and in vitro assays to obtain hit compounds belonging to a new chemical space, excluding peptidyl secondary amides. In total, 180 compounds were subjected to the primary assay at 20 μM, and nine compounds with inhibition rates of >5% were obtained. The IC50 of six compounds was determined in dose-response experiments, with the values on the order of 10-4 M. Although nitro groups were enriched in the substructure of the hit compounds, they did not significantly contribute to the binding interaction in the predicted docking poses. Physicochemical properties prediction showed good oral absorption. These new scaffolds are promising candidates for future optimization.
