Edukacyjne implikacje technologii cyfrowych

W ciągu minionych trzech dekad świat radykalnie się zmienił. Jesteśmy świadkami transformacji od społeczeństwa przemysłowego do społeczeństwa informacyjnego. Jeśli chcielibyśmy określić tą zmianę jednym słowem byłoby nim: cyfryzacja. Początkiem było wynalezienie cyfrowego komputera, a później wszystkie stare analogowe formy medialne (tekst, dźwięk, obraz, film) reprezentowane poprzez ciągłe (analogowe) sygnały zostały zastąpione przez nowe postaci cyfrowe. Pojęcie cyfrowy oznacza, że dowolne informacje mogą być reprezentowana w formie ciągów liczb zapisanych w dwójkowym systemie liczbowym (jako ciąg znaków: 0 i 1). W artykule pokazujemy funkcjonalne ograniczenia mediów analogowych oraz rozważamy korzyści wynikające z cyfrowych reprezentacji różnych form informacji wskazując równocześnie zmiany jakie implikuje to dla procesu uczenia się i edukacji.

„Wyłanianie” się podmiotu w autopojetycznie pojmowanej szkole

Istotą artykułu jest dookreślenia podmiotowości w systemie autopojetycznym, jakim może być szkoła. Na początku postaramy się dookreślić znaczenie rozumienia podmiotu i podmiotowości. Przy czym, poszukując ich źródłowych odniesień odwołamy się do myśli Arystotelesa i Kartezjusza, by następnie poddać je krytyce jako niespełnionych oczekiwań nowożytnej i współczesnej cywilizacji. Jednak, powołując się dalej na poglądy M. Heideggera w tym temacie, okazuje się, że podmiot może być traktowany zgoła inaczej niż opisuje to literatura przedmiotu. Przybliżając zatem inne ujęcie podmiotu, postaramy się wykazać, że wyłania się on na styku jego związku z osobowością, co sugeruje, że to właśnie kształcenie i kształtowanie powinno być traktowane jako najważniejsza dziedzina ludzkiej wiedzy. Dopełnienie tej tezy będzie zatem wymagało wyjaśnienia takich pojęć, jak: osobowość i praktyka edukacyjna. I skoro zatem praktyka edukacyjna jest tak istotna i dla kształtowania osobowości, i wyłaniania się podmiotu, to w dalszej części naszej wypowiedzi położymy nacisk na zinstytucjonalizowaną formę praktyki edukacyjnej czyli nauczanie klasowo-lekcyjne, traktowane jako układ autopojetyczny. Wyjaśnienie znaczenia tego układu będzie stanowić kolejną fazę toczonych tutaj rozważań, a ich celem będzie obrona poglądu, że to, co zostanie „wniesione” do klas szkolnych w postaci zasobów i reguł na początku każdego roku szkolnego, będzie się przekładać na kształtowanie i kształcenie osobowości, i tym samym na możliwości samodoświadczania „Się” podmiotowości. Ponieważ pogląd ten może budzić pewne zastrzeżenia, toteż powołamy się na pewne rozważania dotyczące istnienia tzw. podmiotu rekonstruującego, a więc takiego, który wpisany jest w sens istnienia np. projekcji filmowej, spektaklu teatralnego, czytanej książki.

The ecology of the European hedgehog (Erinaceus europaeus) in rural Ireland

This study on the ecology of Irish hedgehogs (Erinaceus europaeus) has provided information on detection techniques, home range, habitat selection, hedgehog prey, nesting, courtship, genetics, road mortality, parasites, ageing and morphology of this species. Data were obtained from a focal study area in rural Cork, in which 24 radio tagged hedgehogs were monitored from June 2008 to June 2010. Further data were obtained through road kill surveys and the collection of hedgehog carcasses from around Ireland. Hedgehogs of both sexes were found to display philopatry. Habitat was not used in proportion to its availability, but certain habitats were selected and a similar pattern of habitat selection was evident in successive years. Hedgehogs preferred arable land in September and October and, unlike studies elsewhere, were observed to forage in the centre of fields. Badgers were regularly seen at the study site and did not appear to negatively affect hedgehogs’ use of the area. Instead the intra- and inter-habitat distribution of hedgehogs was closely correlated with that of their potential prey. Male hedgehogs had a mean annual home range of 56 ha and females 16.5 ha, although monthly home ranges were much more conservative. Male home range peaked during the breeding season (April-July) and a peak in road deaths was observed during these months. The majority of road kill (54%) were individuals of one year old or less, however, individuals were found up to eight and nine years of age. Genetic analysis showed a distinct lack of genetic variation amongst Irish hedgehogs and suggests colonisation by a small number of individuals. The ectoparasites, Archaeopsylla erinacei, Ixodes hexagonus and Ixodes canisuga were recorded in addition to the endoparasites Crenosoma striatum and Capillaria erinacei. In light of the reported decline in many areas of the hedgehogs’ range, it is a species of conservation concern, and this is the first study examining the ecology of the hedgehog in Ireland.

Evanescent field sensing: optical nanofibres, whispering-gallery-mode microspherical and microbubble resonators

In this thesis, the evanescent field sensing techniques of tapered optical nanofibres and microspherical resonators are investigated. This includes evanescent field spectroscopy of a silica nanofibre in a rubidium vapour; thermo-optical tuning of Er:Yb co-doped phosphate glass microspheres; optomechanical properties of microspherical pendulums; and the fabrication and characterisation of borosilicate microbubble resonators. Doppler-broadened and sub-Doppler absorption spectroscopic techniques are performed around the D2 transition (780.24 nm) of rubidium using the evanescent field produced at the waist of a tapered nanofibre with input probe powers as low as 55 nW. Doppler-broadened Zeeman shifts and a preliminary dichroic atomic vapour laser lock (DAVLL) line shape are also observed via the nanofibre waist with an applied magnetic field of 60 G. This device has the potential for laser frequency stabilisation while also studying the effects of atom-surface interactions. A non-invasive thermo-optical tuning technique of Er:Yb co-doped microspheres to specific arbitrary wavelengths is demonstrated particularly to 1294 nm and the 5S1/2F=3 to 5P3/2Fʹ=4 laser cooling transition of 85Rb. Reversible tuning ranges of up to 474 GHz and on resonance cavity timescales on the order of 100 s are reported. This procedure has prospective applications for sensing a variety of atomic or molecular species in a cavity quantum electrodynamics (QED) experiments. The mechanical characteristics of a silica microsphere pendulum with a relatively low spring constant of 10-4 Nm-1 are explored. A novel method of frequency sweeping the motion of the pendulum to determine its natural resonance frequencies while overriding its sensitivity to environmental noise is proposed. An estimated force of 0.25 N is required to actuate the pendulum by a displacement of (1-2) μm. It is suggested that this is of sufficient magnitude to be experienced between two evanescently coupled microspheres (photonic molecule) and enable spatial trapping of the micropendulum. Finally, single-input borosilicate microbubble resonators with diameters <100 μm are fabricated using a CO2 laser. Optical whispering gallery mode spectra are observed via evanescent coupling with a tapered fibre. A red-shift of (4-22) GHz of the resonance modes is detected when the hollow cavity was filled with nano-filtered water. A polarisation conversion effect, with an efficiency of 10%, is observed when the diameter of the coupling tapered fibre waist is varied. This effect is also achieved by simply varying the polarisation of the input light in the tapered fibre where the efficiency is optimised to 92%. Thus, the microbubble device acts as a reversible band-pass to band-stop optical filter for cavity-QED, integrated solid-state and semiconductor circuit applications.

Silica bonded stationary phases: Innovative functionalization methods and novel chromatographic separations based on molecular recognition

The research work included in this thesis examines the synthesis, characterization and chromatographic evaluation of novel bonded silica stationary phases. Innovative methods of preparation of silica hydride intermediates and octadecylsilica using a “green chemistry” approach eliminate the use of toxic organic solvents and exploit the solvating power and enhanced diffusivity of supercritical carbon dioxide to produce phases with a surface coverage of bonded ligands which is comparable to, or exceeds, that achieved using traditional organic solvent-based methods. A new stationary phase is also discussed which displays chromatographic selectivity based on molecular recognition. Chapter 1 introduces the chemistry of silica stationary phases, the retention mechanisms and theories on which reversed-phase liquid chromatography and hydrophilic interaction chromatograpy are based, the art and science of achieving a well packed liquid chromatography column, the properties of supercritical carbon dioxide and molecular recognition chemistry. Chapter 2 compares the properties of silica hydride materials prepared using supercritical carbon dioxide as the reaction medium with those synthesized in an organic solvent. A higher coverage of hydride groups on the silica surface is seen when a monofunctional silane is reacted in supercritical carbon dioxide while trifunctional silanes result in a phase which exhibits different properties depending on the reaction medium used. The differing chromatographic behaviour of these silica hydride materials prepared using supercritical carbon dioxide and using organic solvent are explored in chapter 3. Chapter 4 focusses on the preparation of octadecylsilica using mono-, di- and trifunctional alkoxysilanes in supercritical carbon dioxide and in anhydrous toluene. The surface coverage of octadecyl groups, as calculated using thermogravimetric analysis and elemental analysis, is highest when a trifunctional alkoxysilane is reacted with silica in supercritical carbon dioxide. A novel silica stationary phase is discussed in chapter 5 which displays selectivity for analytes based on their hydrogen bonding capabilities. The phase is also highly selective for barbituric acid and may have a future application in the solid phase extraction of barbiturates from biological samples.

High School Choral Students' Perceptions of Choral Music Experience

The purpose of this study is to explore high school students' perceptions of their choral experiences, providing an understanding of students' ongoing perspectives of choral experience. Specifically, how have these experiences influenced the formation of their musical identities as members of a choral ensemble? The researcher collected data from the three participants during a full school year. The participants were current students in the researcher's advanced choral ensemble. Through axial coding, three themes emerged: musical interpretation, attitude, and group efficacy. The study revealed that experienced choral students have well-informed musical perspectives that influence their choral experiences. Implications for music education include using students' perspectives for creating rehearsal strategies, planning and programming performances, and fostering a nurturing learning atmosphere. Suggestions for further research include comparing experienced students to non-experienced students, comparing ensembles with student-chosen repertoire to those with director-chosen repertoire, and further examining the impact of choral experience on musical identity.

TALLY HORN! ECHOES OF HOOFBEATS AND HAUNTS: RECORDED SELECTIONS FOR HORN AND PIANO

In the 17th and 18th centuries, the European hunting horn was an instrument associated with the thrill of the chase, rustic scenes, and the pageantry of royal hunts. The sound of this horn and the music that evolved from its heritage would inspire composers writing for the modern horn. TALLY HOrn! Echoes of Hoofbeats and Haunts: Recorded Selections for Horn and Piano are two compact discs of works for horn and piano as well as solo horn reflecting this association with the hunt and include additional works of expressive contrast – lyrical pieces and nocturnes. Nine of the pieces reflect the modern horn’s beginnings and they are Abbot’s Alla Caccia, Berge’s Horn-Lokk, Boutry’s Chassacor, Bozza’s En Fôret, Büsser’s La Chasse de St. Hubert, Pessard’s In the Forest, Piantoni’s Air de Chasse, Schmid’s Im Tiefsten Walde, and Vinter’s Hunter’s Moon. By contrast, three of the selections, Gliére’s Nocturne, Strauss’ Nocturno, and Van Ecchaute’s Nachtpoëma are nocturnes that showcase the expressive quality of the horn. In addition, Bush’s Autumn Poem, Bacon’s Song After the Rain, and Webber’s Summer Pastures are included for their lyric qualities and evocations of nature. The largest work of the project is John Williams’s Concerto for Horn. Its five movements feature both hunting horn traits and expressive qualities. Alejandro Hernandez-Valdez and Grace Cho were the two pianists engaged for the recording. The recording engineer was Edward Kelly. The producer was Carlos Rodriquez. The pieces were recorded at the Spencerville Seventh-day Adventist Church sanctuary in Spencerville, Maryland between November 2010 and February 2011.

Effects of Environmentally Relevant Concentrations of Poultry Litter Associated Contaminates on the Sexual Development of Xenopus laevis

Poultry litter contains high levels of natural sex hormones, nitrogen, phosphorous, and trace amounts of heavy metals. Poultry litter runoff from poultry and farming operations in the Delmarva region can have serious impacts on frog development in the Chesapeake Bay Watershed. In this study, we investigated potential effects of litter compounds on Xenopus laevis development when exposed to environmental levels (0.35 and 0.70 g/L) of litter solution. We found that despite rapid hormone degradation, poultry litter solution still affected X. laevis development. Hormones were also more persistent in the lower poultry litter concentration, leading to even greater effects. Slowed growth and increased female gonadal abnormalities were observed after exposure to 0.35 g/L but not to 0.70 g/L of litter solution, and increased male gonadal abnormalities were observed after treatment to both litter concentrations. The developmental impacts examined in this study may have greater environmental impacts on frog reproduction and survival.

An Investigation into the Efficacy of a pH-Sensitive Material for Milk Spoilage Detection

Ambiguous expiration dates on milk cartons can mislead consumers into prematurely disposing unspoiled milk and potentially drinking spoiled milk. These misconceptions can lead to wastage that harms the environment, or potential discomfort and illness. The incorporation of pH-sensitive indicators into plastic milk cartons has the potential to replace stamped expiration dates as the traditional method of milk spoilage indication. We studied the correlation between bacteria count and milk pH to establish pH measurement as an effective indicator of milk quality. We then developed a method for incorporating bromothymol blue, a pH-sensitive color-changing dye, into a hydrogel made of polyacrylamide. This hydrogel can be added to existing packaging for milk or other products with detectable pH changes. Additionally, we conducted a consumer survey and analyzed current food packaging trends in the market. Our research indicates that a spoilage-indicating milk carton could have strong market potential as food industries increasingly adopt intelligent packaging designs.
