description: The web is essential for business and personal activities well beyond information retrieval, such online banking, financial transactions, and payment authorization, but reliable user authentication remains a challenge.  OpenID is a mainstream Web single sign-on (SSO) solution intended for Internet-scale adoption. There are currently over one billion OpenID-enabled user accounts provided by major content-hosting and service providers (CSPs), e.g., Yahoo!, Google, Facebook, but only a few relying parties that allow users to use their OpenID credentials for SSO. Why is that?

This talk will overview OpenID, and then discuss weaknesses of (1) the protocol and its implementations, (2) the business model behind it, and (3) the user interface. It will conclude with a discussion of a proposal for addressing some of OpenID issues.

description: We study the optical properties of the solar gravitational lens (SGL) while treating the Sun as an extended, axisymmetric and rotating body. The gravitational field of the Sun is represented using a set of zonal harmonics. We develop an analytical description of the intensity of light that is observed in the image plane in the strong interference region of a realistic SGL. This formalism makes it possible to model not only the point-spread function of point sources, but also actual observables, images that form in the focal plane of an imaging telescope positioned in the image plane. Perturbations of the monopole gravitational field of the Sun are dominated by the solar quadrupole moment, which results in forming an astroid caustic on the image plane. Consequently, an imaging telescope placed inside the astroid caustic observes four bright spots, forming the well-known pattern of an Einstein cross. The relative intensities and positions of these spots change as the telescope is moved in the image plane, with spots merging into bright arcs when the telescope approaches the caustic boundary. Outside the astroid caustic, only two spots remain and the observed pattern eventually becomes indistinguishable from the imaging pattern of a monopole lens at greater distances from the optical axis. We present results from extensive numerical simulations, forming the basis of our ongoing study of prospective exoplanet imaging with the SGL. These results are also applicable to describe a large class of gravitational lensing scenarios involving axisymmetric lenses that can be represented using zonal harmonics.

description: We report precise Doppler measurements of GJ317 (M3.5V) that reveal the presence of a planet with a minimum mass Msini = 1.2 Mjup in an eccentric, 692.9 day orbit. GJ317 is only the third M dwarf with a Doppler-detected Jovian planet. The residuals to a single-Keplerian fit show evidence of a possible second orbital companion. The inclusion of an additional Jupiter-mass planet (P = 2700 days, Msini = 0.83 Mjup) improves the quality of fit significantly, reducing the rms from 12.5 m/s to 6.32 m/s. A false-alarm test yields a 1.1% probability that the curvature in the residuals of the single-planet fit is due to random fluctuations, lending additional credibility to the two-planet model. However, our data only marginally constrain a two-planet fit and further monitoring is necessary to fully characterize the properties of the second planet. To study the effect of stellar mass on Jovian planet occurrence we combine our samples of M stars, Solar-mass dwarfs and intermediate-mass subgiants. We find a positive correlation between stellar mass and the occurrence rate of Jovian planets within 2.5 AU; the former A-type stars in our sample are nearly 5 times more likely than the M dwarfs to harbor a giant planet. Our analysis shows that the correlation between Jovian planet occurrence and stellar mass remains even after accounting for the effects of stellar metallicity.

description: This paper studies the ability of markets to alleviate taste-based discrimination in a laboratory experiment. We fnd that markets signifcantly reduce discrimination relative to individual choice situations with the same payoff structure and the same social group membership of the trading partner. We identify three main mechanisms behind this effect. First, the price of prejudice matters in both situations, but signifcantly more so in the market. Second, markets reduce identifcation with one's social group. Third, markets diminish egalitarian preferences. Passive subjects correctly anticipate the main effect. We confrm the main treatment effect in an online experiment with natural groups.

description: We study the quantum properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap which is superimposed by a homogeneous electric field. Trapped Rydberg atoms can be created in long-lived electronic states exhibiting a permanent electric dipole moment of several hundred Debye. The resulting dipole-dipole interaction in conjunction with the radial confinement is demonstrated to give rise to an effectively one-dimensional ultracold Rydberg gas with a macroscopic interparticle distance. We derive analytical expressions for the electric dipole moment and the critical linear density of Rydberg atoms.

description: Η διατριβή εξετάζει την ελληνική παρουσία στην Τσεχία κατά τη μεταπολεμική περίοδο. Οι Έλληνες, που είναι εγκατεστημένοι εκεί, ανήκουν σε τρεις κατηγορίες: η πρώτη περιλαμβάνει τους πρόσφυγες του ελληνικού Εμφυλίου, οι οποίοι έφτασαν εκεί το 1949 και τους απόγονους τους· η δεύτερη είναι οι φοιτητές-υπότροφοι του Κομμουνιστικού Κόμματος Ελλάδος, που στέλνονταν στις χώρες της Ανατολικής Ευρώπης από το 1960 κι έπειτα· και η τρίτη είναι οι Έλληνες που, μετά το 1990 και την πτώση του σοσιαλιστικού καθεστώτος, πήγαν στην Τσεχία ως μετανάστες με σκοπό να δημιουργήσουν μία επιχείρηση. Πρόκειται, λοιπόν, για τρεις κατηγορίες ανθρώπων, οι οποίοι έφτασαν στην Τσεχία σε διαφορετικούς χρόνους, με διαφορετικά κίνητρα, διαφορετικά βιώματα και πιστεύω. Η διατριβή παρουσιάζει τις σχέσεις στο εσωτερικό της κάθε μιας από τις παραπάνω κατηγορίες και αναμεταξύ τους, με ιδιαίτερη έμφαση στις μεταξύ των προσφύγων σχέσεις, καθότι αυτοί αποτέλεσαν διαχρονικά την πολυπληθέστερη κατηγορία.
description: This doctoral thesis examines aspects of life of Greeks living in the Czech Republic. The Greeks that settled there fall into three categories: the first is the refugees from Greek civil war, who arrived in Czechoslovakia in 1949 and their descendants; the second consists of students, scholars of the Communist Party of Greece, who were sent to Eastern Europe from 1960 onwards; and the third group is those who, after 1990 and the fall of the socialist regime, went to the Czech Republic as immigrants in order to establish a business. These three groups arrived at different times in the Czech land, with different motivation and having different experiences and beliefs. This thesis questions the relationships between these groups, with a particular emphasis on the refugees since they were the largest category over time. The aim of this paper is to contribute to the anthropological study of the societies of Eastern Europe in postsocialist era. By this means, focusing on the entire route of the Greeks in Czech Republic, this thesis highlights aspects of the social changes of the last five decades in Eastern Europe; those aspects regard the politics of identity (“national” issue, minorities, refuges) and their representation by the social sciences.
Steepest-descent algorithm for simulating plasma-wave caustics via metaplectic geometrical optics

description: The design and optimization of radiofrequency-wave systems for fusion applications is often performed using ray-tracing codes, which rely on the geometrical-optics (GO) approximation. However, GO fails at wave cutoffs and caustics. To accurately model the wave behavior in these regions, more advanced and computationally expensive "full-wave" simulations are typically used, but this is not strictly necessary. A new generalized formulation called metaplectic geometrical optics (MGO) has been proposed that reinstates GO near caustics. The MGO framework yields an integral representation of the wavefield that must be evaluated numerically in general. We present an algorithm for computing these integrals using Gauss-Freud quadrature along the steepest-descent contours. Benchmarking is performed on the standard Airy problem, for which the exact solution is known analytically. The numerical MGO solution provided by the new algorithm agrees remarkably well with the exact solution and significantly improves upon previously derived analytical approximations of the MGO integral.

Lyman-alpha opacities at z=4-6 require low mass, radiatively-suppressed galaxies to drive cosmic reionization

description: The high redshift Lyman-alpha forest, in particular the Gunn-Peterson trough, is the most unambiguous signature of the neutral to ionized transition of the intergalactic medium (IGM) taking place during the Epoch of Reionization (EoR). Recent studies, e.g. Kulkarni et al. (2019a) and Keating et al. (2019), showed that reproducing the observed Lyman-alpha opacities after overlap required a non-monotonous evolution of cosmic emissivity: rising, peaking at z=6, and then decreasing onwards to z=4. Such an evolution is puzzling considering galaxy build-up and the cosmic star formation rate are still continously on the rise at these epochs. Here, we use new RAMSES-CUDATON simulations to show that such a peaked evolution may occur naturally in a fully coupled radiation-hydrodynamical framework. In our fiducial run, cosmic emissivity at z>6 is dominated by a low mass (M$_{\rm DM}<2.10^9$ M$_{\odot}$), high escape fraction halo population, driving reionization, up to overlap. Approaching z=6, this population is radiatively suppressed due to the rising ionizing UV background, and its emissivity drops. In the meantime, the high mass halo population builds up and its emissivity rises, but not fast enough to compensate the dimming of the low mass haloes, because of low escape fractions. The combined ionizing emissivity of these two populations therefore naturally results in a rise and fall of the cosmic emissivity, from z=12 to z=4, with a peak at z=6. An alternative run, which features higher escape fractions for the high mass haloes and later suppression at low mass, leads to overshooting the ionizing rate, over-ionizing the IGM and therefore too low Lyman-alpha opacities.

description: We introduce a method based on the loudest event statistic to calculate an upper limit or interval on the astrophysical rate of binary coalescence. The calculation depends upon the sensitivity and noise background of the detectors, and a model for the astrophysical distribution of coalescing binaries. There are significant uncertainties in the calculation of the rate due to both astrophysical and instrumental uncertainties as well as errors introduced by using the post--Newtonian waveform to approximate the full signal. We catalog these uncertainties in detail and describe a method for marginalizing over them. Throughout, we provide an example based on the initial LIGO detectors.

description: Using three-dimensional k.p calculation including strain and piezoelectricity, we showed that the size of the quantum dot (QD) in the growth direction determines the influence of the (In,Ga)As capping layer on the optical properties of [11k] grown InAs QDs, where k=1,2,3. For flat dots, increase of In concentration in the capping layer leads to a decrease of the transition energy, as is the case of [001] grown QDs, whereas for large dots an increase of the In concentration in the capping layer is followed by an increase of the transition energy up to a critical concentration of In, after which the optical transition energy starts to decrease.

description: The aim of the present thesis was to create a grammar of the nominal color terms in Modern Greek. This grammar includes information on their construction processes (prefixation, suffixation, composition, conversion), on the elements that participate in them, on the restrictions imposed by their application as well as on the deviations and peculiarities in their morphology, syntax and semantics. Furthermore, we applied our theoretical findings in the context of lexicography: we proposed a model of a dictionary of color terms and constructed an electronic dictionary of compound names that appear in specific semantic fields. Finally, we presented our teaching intervention within the context of teaching Greek as a second / foreign language, together with statistic conclusions regarding the effectiveness of our teaching and the extent of the participants’ acquisition.

description: Data obtained during continuous biological reduction of Pb(II) in an Upflow Anaerobic Sludge Blanket Reactor. The main objective of this study was to achieve the continuous biorecovery and bioreduction of Pb(II) using an industrially obtained consortia as a biocatalyst. An upflow anaerobic sludge blanket reactor was used in the treatment process. The bioremediation technique that was applied made use of a yeast extract as the microbial substrate and Pb(NO3)2 as the source of Pb(II). The UASB reactor exhibited removal efficiencies of between 90 and 100% for the inlet Pb concentrations from 80 to 2000 ppm and a maximum removal rate of 1948.4 mg/(L·d) was measured. XRD and XPS analyses of the precipitate revealed the presence of Pb0, PbO, PbS and PbSO4. Supporting experimental work carried out included growth measurements, pH, oxidation–reduction potentials and nitrate levels.

Η μαγεία, η πανάρχαια αυτή τέχνη, δεν αποτέλεσε καινούριο φαινόμενο για τον χριστιανικό κόσμο. Συνοδευόμενη από παγανιστικές τελετές και ειδωλολατρικά έθιμα ταυτίστηκε άμεσα, στους πρώτους μετά – χριστιανικούς αιώνες, με την λατρεία των δαιμόνων. Οι Πατέρες και οι εκκλησιαστικοί συγγραφείς δίδαξαν την μοναδικότητα του αληθινού Θεού και την ματαιότητα των εθνικών θεοτήτων. Γι’ αυτό και όταν οι μάγοι στις τελετές τους επικαλούνταν τους εθνικούς θεούς, στα μάτια των χριστιανών η αναφορά τους γινόταν στους ίδιους τους δαίμονες. Η χριστιανική διδασκαλία θα καταδικάσει τις μαγικές πρακτικές με το επιχείρημα ότι ο διάβολος και τα πειθήνια όργανά του, οι δαίμονες, είναι οι δημιουργοί της μαγείας και αποβλέπουν στον όλεθρο της ανθρώπινης ψυχής. Οι Πατέρες της Δύσης θα ξετυλίξουν τον μίτο της μαγικής απάτης και θα ξεσκεπάσουν τη δαιμονική πλάνη. Καταληκτικά, σταχυολογώντας τις λατινικές πηγές, ξεχωρίζει η διδασκαλία του ιερού Αυγουστίνου. Ο Χριστιανός φιλόσοφος θα αναφερθεί στον πονηρό ρόλο των δαιμόνων και θα συνδυάσει τη δράση τους, άρρηκτα, με τις μαγικές απάτες. Ο πιστός οφείλει να ακολουθεί τον δρόμο του Κυρίου και να αποφεύγει να συναναστρέφεται με μάγους και αστρολόγους, καθώς η αλήθεια βρίσκεται μόνο στη χριστιανική πίστη.
description: In this thesis is attempted to be investigated, until the time of St. Augustine, the attitude of the Fathers and ecclesiastical writers of the West towards the magical practices. The magic, this ancient art, was not a new phenomenon for the Christian world. Accompanied by pagan rites and pagan traditions was identified, directly, in the first post - Christian times, with the worship of demons. In particularly, the Fathers and ecclesiastical writers taught the Word of God and the vanity of the pagan deities. The magicians in their ceremonies did not invoke the pagan deities, but their own demons. The Christian teaching renounces the magical practices. The Devil and his docile demons are the creators of magic. Their aim is the destruction of the human soul. The Fathers of the West will reveal the demonic delusion. Concluding, through the Latin sources, stand out the sacred teachings of St. Augustine. The Christian philosopher refers to the role of the evil demons and combines their action with magical tricks. The true Christian must follow the way of the Lord God, and avoid the evil magicians and astrologers, because the truth is found only in the Christian faith.

description: The aim of this dissertation is to present the referral of the accused to the court through a final bill of indictment issued by the Judicial Council of the Court of Appeal. This study attempts to thoroughly investigate and profoundly analyze and record all problems resulting from this particular model of referral, which now applies to the crimes provided in article 1 of Law 1608/1950 and those falling under the scope of Law 4022/2011. In this context, this study attempts an overall understanding of the referral of the accused to open court, the way it used to apply and the way it currently applies in Greece and in other countries, while displaying and analyzing all theoretical discussions about this issue. This is followed by a study of the final bill of indictment issued by the Judicial Council of the Court of Appeal through the prism of its interrelation with other models of referral of the accused, a subject, which is rather difficult to approach. The following issues are also set out and analyzed: additional investigation in the field of the final bill of indictment issued by the Judicial Council of the Court of Appeal, issues related to the finality of such a bill and its scope, procedural coercion measures in this field, and compatibility of this particular model with the rules of increased formal legal force.

Η ερευνητική προσέγγιση εφαρμόστηκε στη γνωστική ενότητα των μαθηματικών και συγκεκριμένα στις πράξεις της πρόσθεσης και της αφαίρεσης. Η μέθοδος που εφαρμόστηκε ήταν η έρευνα -δράση. Τα αποτελέσματα της έρευνας έδειξαν ότι τα παιδιά έμαθαν να προσαρμόζουν το χώρο της τάξης στις επιθυμίες τους και τις ανάγκες των μαθηματικών δραστηριοτήτων. Ανέπτυξαν συνεργατικές και κοινωνικές δεξιότητες, μεταγνώση, έμαθαν να αυτοαξιολογούν τη συμπεριφορά τους και τον τρόπο εργασίας τους στην ομάδα, να εκφράζουν τα συναισθήματά τους και να βελτιώνουν τη συμπεριφορά και τις επιδόσεις τους συζητώντας για τη δράση τους. Οδηγήθηκαν στην κατάκτηση γνώσεων στα μαθηματικά με ενεργητικό τρόπο. Οι αλλαγές στη διαρρύθμιση και την αισθητική του χώρου κατά την εργασία των παιδιών στις ομάδες δημιούργησαν μία ‘συνομορφία’ που οδήγησε και στη δημιουργία μίας ‘περιβαλλοντικής αλληλεξάρτησης’ στο εκπαιδευτικό περιβάλλον του νηπιαγωγείου.
description: The aim of this thesis is the systemic approach of the pedagogical development of space and the implementation of the cooperative learning in kindergarten. It was developed in the mathematics section and specifically on the field of addition and subtraction. The method was the action research. Results have indicated that children learned how to change/modify the classroom space according to their needs and to the needs of the mathematical activities. They developed cooperative and social skills, post knowledge efficiency, and they learned to self-evaluate their attitude and their work during teamwork and to express their feelings. They conquered math skills in an active way and by discussing their mathematical action. The changes/modifications regarding the arrangements and aesthetics of the school setting with correlation of the cooperative learning created a ‘synomorfy’ which led to an ‘environmental interdependence’ in the educational environment of the kindergarten.
Not-for-profit agencies and privatization
Creators: name: Terpenning, Greg Eldon
Publisher: name: University of British Columbia
Year: 2010

description: This study examines the impact of provincial government privatization initiatives on voluntary organizations that provide personal social services in Vancouver. A variety of key personnel in each of six very diverse agencies are interviewed, and the data from -these interviews is then qualitatively analyzed. The data suggests that: (1) organizations which are perceived to voluntarily alter their mission in response to privatization experience internal division, (2) dependence on contracting can pose a threat to the fundamental operating principles of an organization if those principles do not conform to a bureaucratic ideal, (3) there is a wide range of opinion within the voluntary sector regarding the motives of the provincial government for pursuing privatization, that these opinions have both a descriptive and a prescriptive function, and therefore relate to differences in the response of individual agencies to privatization, (4) that contracting alone is not an effective means for an agency to meet the additional demands that result from the reduction and elimination of public services, (5) that competition has generally increased throughout the voluntary sector as a result of privatization, (6) that privatization has resulted in gaps in service which it has become the de facto responsibility of the voluntary sector to address, and (7) that the decision-making structure of an organization is the most constant determining factor in regard to which opinion of government motivation will guide an agency's response to privatization. Concerns raised by professional associations and researchers in the field of social work regarding the potential negative implications of privatization for voluntary organizations are partially supported by this study. A theory of the impact of privatization on voluntary organizations is generated from the data.

description: We investigate a well studied system of a quantum dot coupled to a Coulomb box and leads, realizing a spin-flavor Kondo model. It exhibits a recently discovered non-Fermi liquid (NFL) behavior with emergent SO(5) symmetry. Here, through a detailed bosonization and refermionization solution, we push forward our previous work and provide a consistent and complete description of the various exotic properties and phase diagram. A unique NFL phase emerges from the presence of an uncoupled Majorana fermion from the flavor sector, whereas FL-like susceptibilities result from the gapping out of a pair of Majroana fermions from the spin and flavor sectors. Other properties, such as a $T^{3/2}$ scaling of the conductance, stability under channel or spin symmetry breaking and a re-appearance of NFL behavior upon breaking the particle-hole symmetry, are all accounted for by a renormalization group treatment of the refermionized Majorana model.

description: A promising technique for the spectral design of acoustic metamaterials is based on the formulation of suitable constrained nonlinear optimization problems. Unfortunately, the straightforward application of classical gradient-based iterative optimization algorithms to the numerical solution of such problems is typically highly demanding, due to the complexity of the underlying physical models. Nevertheless, supervised machine learning techniques can reduce such a computational effort, e.g., by replacing the original objective functions of such optimization problems with more-easily computable approximations. In this framework, the present article describes the application of a related unsupervised machine learning technique, namely, principal component analysis, to approximate the gradient of the objective function of a band gap optimization problem for an acoustic metamaterial, with the aim of making the successive application of a gradient-based iterative optimization algorithm faster. Numerical results show the effectiveness of the proposed method.

description: We study a four-dimensional domain wall in twisted M-theory. The domain wall is engineered by intersecting D6 branes in the type IIA frame. We identify the classical algebra of operators on the domain wall in terms of a higher vertex operator algebra, which describes the holomorphic subsector of a 4d $\mathcal{N}=1$ supersymmetric field theory, and compute the associated mode algebra. We conjecture that the quantum deformation of the classical algebra is isomorphic to the bulk algebra of operators from which we establish twisted holography of the domain wall.

description: In theories beyond the Standard Model, in particular in theories with extra spatial dimensions such as superstring theory, there are a large number of scalar fields which appear in the low energy effective action. These moduli fields must be stabilized. Often, moduli stabilization involves a stage during which the moduli fields oscillatte coherently about their ground state value. Here, we study moduli and graviton production during the period during which the background modulus field is oscillating, assuming that this period takes place in the radiation phase. We find a resonant production of moduli fluctuations, and a tachyonic instability to the generation of long wavelength gravitational waves. As a consequence, the period of moduli stabilization is short on a Hubble time scale.

description: We calculate the sensitivity of the inversion spectrum of ammonia to possible time-variation of the ratio of the proton mass to the electron mass, mu=m_p/m_e. For the inversion transition (lambda= 1.25 cm^{-1}) the relative frequency shift is significantly enhanced: delta(omega)/omega=-4.46, delta(mu)/mu. This enhancement allows one to increase sensitivity to the time-variation of mu using NH_3 spectra for high redshift objects. We use published data on microwave spectra of the object B0218+357 to place the limit delta(mu)/mu =(0.6 +/- 1.9) 10^{-6} at redshift z=0.6847; this limit is several times better than the limits obtained by different methods and may be significantly improved. Assuming linear time dependence we obtain dot{mu}/mu=(-1 +/- 3) 10^{-16} yr^{-1}.

description: In this dissertation, a study of ZZ and ZZ* production in proton-proton collisions at the large hadron collider (LHC) at CERN is presented. The data analyzed in this study were recorded by the ATLAS experiment at a centre-of-mass energy of 7 TeV and of 8 TeV. We select events consistent with fully leptonic ZZ decays, in particular to electrons and muons. The total ZZ production cross section is measured and is found to be in agreement with the standard model prediction. The ZZ production allows the study of the anomalous neutral triple gauge couplings. No deviation from the standard model prediction is found that could indicate the the presence of new physics. In view of the forthcoming increase of the instantaneous luminosity of LHC, the ATLAS collaboration foresees upgrades of the detector. In this doctoral thesis, an upgrade of the muon spectrometer is also presented.

description: We propose and demonstrate the digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities using a self-limiting atomic layer deposition technique. Control of resonances in discrete steps of 122 +/- 18 pm per hafnium oxide atomic layer is achieved through this post-fabrication process, nearly linear over a full 17 nm tuning range. The cavity Q is maintained in this perturbative process, and can reach up to its initial values of 49,000 or more. Our results are highly controllable, applicable to many material systems, and particularly critical to matching resonances and transitions involving mesoscopic optical cavities.

description: The construction of catalogues of a particular type of galaxy can be complicated by interlopers contaminating the sample. In spectroscopic galaxy surveys this can be due to the misclassification of an emission line; for example in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) low redshift [OII] emitters may make up a few percent of the observed Ly$α$ emitter (LAE) sample. The presence of contaminants affects the measured correlation functions and power spectra. Previous attempts to deal with this using the cross-correlation function have assumed sources at a fixed redshift, or not modelled evolution within the adopted redshift bins. However, in spectroscopic surveys like HETDEX, where the contamination fraction is likely to be redshift dependent, the observed clustering of misclassified sources will appear to evolve strongly due to projection effects, even if their true clustering does not. We present a practical method for accounting for the presence of contaminants with redshift-dependent contamination fractions and projected clustering. We show using mock catalogues that our method, unlike existing approaches, yields unbiased clustering measurements from the upcoming HETDEX survey in scenarios with redshift-dependent contamination fractions within the redshift bins used. We show our method returns auto-correlation functions with systematic biases much smaller than the statistical noise for samples with at least as high as 7 per cent contamination. We also present and test a method for fitting for the redshift-dependent interloper fraction using the LAE-[OII] galaxy cross-correlation function, which gives less biased results than assuming a single interloper fraction for the whole sample.

description: Photoluminescence is commonly used to identify the electronic structure of individual nanotubes. But, nanotubes naturally occur in bundles. Thus, we investigate photoluminescence of nanotube bundles. We show that their complex spectra are simply explained by exciton energy transfer between adjacent tubes, whereby excitation of large gap tubes induces emission from smaller gap ones via Forster interaction between excitons. The consequent relaxation rate is faster than non-radiative recombination, leading to enhanced photoluminescence of acceptor tubes. This fingerprints bundles with different compositions and opens opportunities to optimize them for opto-electronics.

Effect of self-referral instruction on grade 4 students' utilization of school nursing sevices

description: This study examined the effect of self-referral instruction on Grade 4 students' utilization of school nursing services. Self-referral is a skill needed for self-care. Adult self-care has received emphasis by consumers and health professionals. The focus on adult self-care has not, however, achieved the goal of consumers taking more responsibility for their health. It has been suggested that childhood may be the most appropriate time to teach self-care skills. A review of the literature demonstrated, however, that little is known about child self-care and childrens’ learning and use of the specific skills and knowledge needed to practice self-care. This study therefore contributes to a currently inadequate knowledge base and enhances the ability of nurses to make objective decisions about Instruction of children in the use of a self-care skill, self-referral, in the school setting when nursing time is limited. This experimental study involved 78 Grade 4 students from four schools. The students were randomly assigned to a group that either would or would not be taught self-referral to the school nurse. There were two 20 minute lessons given to the experimental group, a pre and post study questionnaire was given to both groups prior to the lessons and nine weeks later at the conclusion of the study. The questionnaire collected data about the students' knowledge of the school nurse's accessibility, their willingness to self-refer, and their knowledge concerning appropriate reasons to use self-referral, information was also collected from the nurses regarding what students used self-referral and the problems they presented. Analysis of variance and chi-square were selected as appropriate statistical methods of analysis. The findings demonstrated that children who were given instruction in self-referral had significantly greater knowledge about how, when, and why to self-refer. Instruction in self-referral did not, however, encourage a significant number of children to practice this skill as only four children from the experimental group self-referred. It is speculated from comparing the number of self-referrals between the schools that the placement of the self-referral appointment books in the schools was a factor that affected the students' decisions to self-refer, it appears it is important that the book be placed where the children feel comfortable writing in it. Such a place may be away from the scrutiny of adults while providing as much privacy as possible. Based upon this study's findings, implications for nursing practice and recommendations for further research were described.
