The ITS-90 after definition of neon isotopic reference composition. Extent of the isotopic effect on previous inter-comparison results

Starting from the end of the past century, the importance has been recognized of the effect of isotopic composition on some of the temperature fixed points for the most accurate realizations of the ITS-90. In the original definition of the latter, dating back to 1990, only a generic reference was made to natural composition of the substances used for the realization of the fixed points, except for helium. The definition of a reference isotopic composition for three fixed points, e-H2, Ne and H2O, while eliminating the non-uniqueness of the Scale in this respect, induced detectable differences in the present and future realizations of the Scale, at the highest accuracy level, with respect to the previous realizations, when they affected the results of past key comparisons, namely the K1 and K1.1, and K2 and K2.1 to K2.5 and the related regional and supplementary ones. The paper provides evidence of the extent of this effect by using the results of the relevant key comparisons for Neon archived in the BIPM KCDB, and of other comparisons existing in the literature: 1979-1984, 2007-2012 and 2009-2010 sealed cell comparisons; and discusses the meaning and the outcomes of this evaluation.Comment: 19 pages, 4 figures, 4 tables.

Preference Assessment of Teacher Behaviors for Students with Autism and resulting Behaviors

With the rising prevalence of autism spectrum disorder (ASD), studies must seek to evaluate enriched, innovative teaching experiences for this growing population. Preference assessments are widely used to evaluate favored edibles, objects and activities for children with ASD. Less research has been conducted regarding children’s preferences for staff. Since children with ASD spend a large part of their day with teachers in their schools or therapeutic environments, it seems fitting that they would develop a preference for teachers. If students develop preferences for teachers, it would also make sense that these preferences may have an effect on the student’s behavior. Two students with autism and their everyday teachers participated in this study. A multiple-stimulus without replacement preference assessment using pictorial presentation established a hierarchy for the student’s preference for particular teachers. Teachers were ranked as either high or low preference for the student. The effect of each student’s preference for a particular teacher on the student’s behavior was compared in an alternating treatment design. The purpose of this study was to demonstrate a relation between preference for particular teachers and student task performance while completing a task in which they had previously displayed problem behavior. Participants worked in a 1:1 instructional setting for 5 minute intervals. A 10-second partial- interval recording method was used to document the occurrence of problem behavior. As hypothesized, both students engaged in lower rates of problem behavior while working with their highest preferred teacher. Further research is needed to elucidate the cause of this relationship

A Multiple Case Exploration Of Designers And Reflection In The Design Space

For decades, scholars have searched for ways to more effectively teach and practice instructional design. A variety of strategies have been employed to address the ambiguity in and challenges of the field. Much of the focus in the education of instructional designers has been on teaching students how best to use the many models developed for the field (Rowling, 1992). These efforts, while meant to help the new instructional designer succeed, have often been stifled by the ever-changing landscape of what instructional designers are asked to do in their roles after graduation (Kenny, Zhang, Schwier, & Campbell, 2005). Other research centers around the ways students can fuse their new instructional design knowledge with practical activities. While many scholars have begun to focus on alternative methods for preparing instructional designers and improving instructional design processes, instructional designers themselves have been neglected. We teach instructional designers about the profession before we have truly understood the professional. From a teaching standpoint, this approach contradicts the very foundation of instructional design education: that of recognizing that the learners/users are at the center of instructional design (Cennamo & Kalk, 2004). The purpose of this qualitative study was to examine instructional designers during design by engaging them in structured reflection as (a.) a way to better understand instructional designers in the design space and (b.) a technique for instructional designers to improve their design. Seven designers were asked to explore their thoughts, feelings, and experiences over six weeks while engaged in a design project. This study used various data collection methods including reflection journals, interviews, and surveys. The Self-Reflection Insight Scale (SRIS) and REFLECT rubric were utilized to measure reflection abilities, and grounded theory was employed to conceptualize the data (Strauss & Corbin, 1990), while concentrating on discovery and the development of theory (Charmaz, 1983). Results showed that each designer is unique; designers rely on distinctive designer precedents; designers perceive reflection to positively impact their design products; designers\u27 depth of reflection waxes and wanes; and designers reflect more deeply when provided with feedback

New data on heavy minerals from the Upper Cretaceous-Paleogene flysch of the Beskid Śląski Mts. (Polish Carpathians)

The types, abundance and origin of non-opaque heavy minerals from 17 samples of sandstones and granule conglomerates of the Godula Beds, Upper Istebna Sandstone, Ciężkowice and Cergowa Sandstone (Upper Cretaceous-Paleogene) of the Beskid Śląski Mts. are described in this study. The descriptions are based on standard optical petrographic investigations and on scanning electron microscope (including electron microprobe) analysis. Garnet, rutile, zircon and tourmaline are the most common types of heavy minerals. Monazite and apatite occur subordinately, whereas epidote and spinel are sporadic. The heavy minerals from the Middle and Upper Godula Beds and the Upper Istebna Sandstone indicate original derivation mainly from metamorphic rocks of granulite and partly eclogite facies. Metasediments were significant constituents, with subordinate granitoids and hornfelses. Granitoids and corresponding pegmatites and aplites, as well as metapelites and metapsammites, appear to be the primary crystalline parent rocks of the Lower Godula Beds and the Ciężkowice Sandstone. Garnet-mica schists with subordinate granitoids and their pegmatites are interpreted as the main crystalline parent rocks of the Cergowa Sandstone. Sporadic chromian spinels and chromian pyrope indicate derivation from mafic and ultramafic rocks. Co-occurrence of rounded and fresh unabraded grains (sometimes euhedral) suggests a mixed provenance for the clastic material, both from crystalline and older sedimentary rocks

Searching key macro-factors for cooperation in cross-border tourism : institutional matrix vs. PEST concept

Purpose: This study presents the concepts of identification and operationalization of key success factors of cross-border cooperation and their interpretation from the perspective of economics and management sciences. Design/Methodology/Approach: The contribution is based on the three-stage research process, a qualitative assessment of the macro-environment factors. Concepts of the institutional matrix and the PEST method were used in the analysis. Findings: Four key elements of the macro environment were identified: state policy, focused on the development of cross-border tourism; tax policy; infrastructure; and the power of the economy. These factors, besides being elements of the institutional matrix for the cross-border tourism sector (economic perspective), they are also of key importance for cooperation success in the strategic context at the level of enterprise (management sciences perspective). Practical Implications: The identified factors should be taken into account in designing public policies and strategies of enterprises. Originality/Value: New knowledge of relevance from an economic and management sciences’ perspective. The added value of this text is to direct the scientific discussion concerning reality to a two-dimensional plane of analysis, leading to joint conclusions.peer-reviewe

Katolickie tradycje liturgiczne w Anglii w okresie przedreformacyjnym i ich wpływ na The Order of the Communion z 1548 r.

Polscy badacze zajmujący się historią oraz historią liturgii dotychczas pomijali, bądź też baga- telizowali tematykę związaną z obrządkami Mszy św. i angielskimi tradycjami liturgicznymi doby przedreformacyjnej. Wydaje się to niesprawiedliwe, szczególnie w kontekście badania początków reformacji w Anglii oraz źródeł, na których oparto nowe formy liturgiczne, stworzone u schyłku pierwszej połowy XVI w. Celem artykułu jest przybliżenie zwyczajów diecezji Salisbury i York oraz zestawienie ich z nową formą Mszy, przygotowaną przez Tomasza Cranmera. Analiza zmian, jakie zaszły w tym czasie na gruncie liturgii angielskiego Kościoła państwo- wego, wskazuje na ich niejednoznaczny charakter. Dla wielu mieszkańców królestwa, po 1534 r. (Akt supremacji) jedyną zmianą był fakt, że na czele Kościoła zamiast papieża stanął król i to jego wymieniano w Kanonie. Niemal niezmienione natomiast aż do 1548 r. pozostały kwestie związane z liturgią Mszy św. (forma, obrzędy), natomiast średniowieczne katolickie zwyczaje liturgiczne, stały się gruntem, na którym powstał Porządek Komunii (The Order of the Communion)

Modifying Interfacial Polymerization Reaction Conditions in High-Pressure Membrane Fabrication for Enhanced Organic Micropollutant Removal

The overall goal of this dissertation was to evaluate the removal of organic micropollutants by high-pressure membranes (both commercial and in-house varieties) and assess how interfacial polymerization (IP) reaction conditions employed in high-pressure membrane fabrication affect membrane performance. In support of this goal, the following specific objectives were pursued: (i) evaluate the effects of zeolite thin-film nanocomposite (TFN) membrane fabrication variations on the removal of a subset of organic micropollutants commonly found in wastewater effluent; (ii) elucidate whether changes in membrane fabrication parameters yield the same effects on thin-film composite (TFC) and zeolite TFN membrane performance; (iii) assess whether IP in TFC membrane fabrication is inherently self-limiting, and evaluate the effects of constant m-phenylenediamine (MPD) supply during IP in the modification of existing, and fabrication of new, TFC membranes; and (iv) evaluate the impacts of membrane type, IP reaction modifications, and per-and polyfluoroalkyl substances (PFAS) physicochemical characteristics on PFAS removal by high-pressure membranes. Fabrication variables that resulted in improved water flux and high levels of organic micropollutant rejection in TFCs and zeolite TFNs were identified, and it was found that these variables yielded similar trends in performance between the two membrane types. Further, it was demonstrated that IP in TFCs is not inherently self-limiting, and an innovative approach to TFC modification was developed using MPD permeation through TFC active layers to form additional polyamide. This approach was adapted to TFC fabrication, and identified as a novel variable to employ in the production of TFCs. High-pressure membranes were also found to be an effective treatment technology for PFAS removal and displayed a broad range of performance when treating PFAS-contaminated groundwater; PFAS rejection was highest among fully aromatic polyamide TFCs (including those modified with additional active layer formation) and lowest among semi-aromatic polyamide TFCs. Overall, this work provides valuable insights into TFC membrane modification and fabrication strategies that can be employed in the production of high-pressure membranes for enhanced organic micropollutant removal.Doctor of Philosoph

Vacuum and Residual Gas Composition MEMS Sensor

AbstractThe paper presents a MEMS-type vacuum and residual gas composition sensor, which in contrast to the other miniature sensors, works in medium and high vacuum (10−5−10Pa). It operates on the principle of ionization of gases inside a silicon-glass microchamber. Pressure is estimated on the basis of the discharge current value, and gas composition − on the basis of spectra of the glowing gases, recorded by a miniature fiber spectrometer
