description: Cities are not affected by global climate policy and the Kyoto Protocol - however many of them engage in voluntary activities. This paper analyses how communities in general and especially the city of Hamburg can contribute to global climate protection in their citypartnerships according to the slogan "think global, act local". Possible activities are in the fields of awareness-raising, capacity-building, exchange of experiences and joint project implementation. A focus is layed on projects according to the Clean Development Mechanism of the Kyoto Protocol in north-south citypartnerships. There is a clear potential for reduction of transaction costs in this kind of projects due to the institutional links of the citypartnership. For Hamburg, CDM-potential is high in its partnership with Shanghai. Further possibilities for action are micro-projects with a strong development component in the partnership with Léon (Nicaragua), exchange of experience with the city of Chicago on its emission trading scheme and adaptation activities especially against sea-/riverlevel rise with the cities of Osaka, Dresden and Marseille.

description: This paper contains the results of research on the determination of groups of students who have difficulty learning in geometry material of three-dimensional space. Determination of student groups is done by cluster analysis method based on variables of learning difficulties. The sample used was 53 students of class XI of SMA Negeri 1 Bendahara, Aceh Tamiang District. To see the similarity between respondents who will be grouped into one group, the Euclidean distance measure is used by considering the score of each variable of learning difficulties. By using average linkage, the results show that there are 3 groups of students who have difficulty learning geometry in the three dimensional space, low difficulty cluster 1 as many as 27 students which are characterized by the lowest average value in variable 3 (visual-motor association), variable 4 (perseveration) , variable 5 (difficulty recognizing and understanding symbols) and variable 6 (difficulties in language and reading), cluster 2 moderate difficulties as many as 22 students which are indicated by the lowest average value on variable 1 (spatial relationship disorder) and variable 2 (perception abnormality visual), 4 high difficulty clusters are 4 students which are marked by the highest average score for each variable. By using ward, it was found that there were 3 groups of students who had difficulty learning geometry in the three dimensional space, low difficulty, cluster 1 as many as 26 students which was indicated by the lowest average value in variable 3 (visual-motor association), variable 5 (difficulty recognizing and understand the symbol) and variable 6 (difficulty in language and reading); cluster 2, high difficulty as many as 17 students which is indicated by the highest average value in variable 3 (visual-motor association), variable 4 (perseveration) and variable 6 (difficulty in language and reading), and cluster 3, moderate difficulty as many as 10 students marked by the lowest average value in variable 4 (perseveration).
Who are you talking about? : the development of reference in Cantonese-speaking children with and without specific language impairment
Creators: name: Wong, Mei Yin Anita
Publisher: name: University of British Columbia
Year: 2009

description: Cantonese-speaking children's reference to story characters was examined in three different functions: Maintenance of a known character, Introduction of a second new character, and Reintroduction of a known character. The notion of discourse representation, specified in terms of Levelt's (1989L).knowledge components and attentional states, was used as the framework for understanding presupposition as cognitive process. Typically developing children aged 3, 5, 7 and 12 years and a group of 5-year-olds with specific language impairment, told 16 stories based on picture sequences. A child's referential act was judged to be adequate when a naive 'listener' could successfully identify the character. All of the children were the most referentially adequate with Maintenance, less adequate with Introduction, and least adequate with Reintroduction. The 12- and 7-yearolds approached ceiling on all three functions, indicating accurate presupposition of the listener's knowledge of, and attention state towards, the story characters, as well as knowledge of the referring expressions. The 5-year-olds Maintained and Introduced characters clearly. They had the required expressions and made accurate presuppositions about the listener's knowledge. However, despite knowledge of the required expressions, they only showed partial success on Reintroduction, indicating difficulties in presupposing the listener's relative attentional state towards the character. The 3-year-olds were only referentially adequate on Maintenance. Despite knowledge of the required expressions, they appeared to ignore the listener's knowledge state. Generally, children were more successful when Introducing or Reintroducing a character late rather than early in the discourse, suggesting that the salience of a new or returning character was a stronger determinant than the relative complexity of the discourse representation. Cantonese-speaking children with SLI showed the same effects of referential function and discourse position. Some were at the same developmental level as their language-matched peers and some as their age-matched peers. However, they showed more difficulty with the required referring expressions than either group of children at the same levels. Future challenges would be to determine if children with SLI have problems with linguistic forms only, or with presuppositional skills as well.

description: Pull request (PR) based development, which is a norm for the social coding platforms, entails the challenge of evaluating the contributions of, often unfamiliar, developers from across the open source ecosystem and, conversely, submitting a contribution to a project with unfamiliar maintainers. Previous studies suggest that the decision of accepting or rejecting a PR may be influenced by a diverging set of technical and social factors, but often focus on relatively few projects, do not consider ecosystem-wide measures, or the possible non-monotonic relationships between the predictors and PR acceptance probability. We aim to shed light on this important decision making process by testing which measures significantly affect the probability of PR acceptance on a significant fraction of a large ecosystem, rank them by their relative importance in predicting PR acceptance, and determine the shape of the functions that map each predictor to PR acceptance. We proposed seven hypotheses regarding which technical and social factors might affect PR acceptance and created 17 measures based on them. Our dataset consisted of 470,925 PRs from 3349 popular NPM packages and 79,128 GitHub users who created those. We tested which of the measures affect PR acceptance and ranked the significant measures by their importance in a predictive model. Our predictive model had and AUC of 0.94, and 15 of the 17 measures were found to matter, including five novel ecosystem-wide measures. Measures describing the number of PRs submitted to a repository and what fraction of those get accepted, and signals about the PR review phase were most significant. We also discovered that only four predictors have a linear influence on the PR acceptance probability while others showed a more complicated response.

description: We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodelled gravitational-wave bursts in 473 hr of coincident data collected during early 2003. No candidate signals were found. We set an upper limit of 0.12 events per day on the rate of detectable gravitational-wave bursts, at 90% confidence level. From simulations, we estimate that our detector network was sensitive to bursts with root-sum-square strain amplitude above approximately 1-3x10^{-19} Hz^{-1/2} in the frequency band 700-2000 Hz. We describe the details of this collaborative search, with particular emphasis on its advantages and disadvantages compared to searches by LIGO and TAMA separately using the same data. Benefits include a lower background and longer observation time, at some cost in sensitivity and bandwidth. We also demonstrate techniques for performing coincidence searches with a heterogeneous network of detectors with different noise spectra and orientations. These techniques include using coordinated signal injections to estimate the network sensitivity, and tuning the analysis to maximize the sensitivity and the livetime, subject to constraints on the background.

description: By means of a new mod(N)-invariant operator basis, s-parametrized phase-space functions associated with bounded operators in a finite-dimensional Hilbert space are introduced in the context of the extended Cahill-Glauber formalism, and their properties are discussed in details. The discrete Glauber-Sudarshan, Wigner, and Husimi functions emerge from this formalism as specific cases of s-parametrized phase-space functions where, in particular, a hierarchical process among them is promptly established. In addition, a phase-space description of quantum tomography and quantum teleportation is presented and new results are obtained.

description: In this paper we consider all consistent extensions of the AdS_5 x S^5 superalgebra, psu(2,2|4), to incorporate brane charges by introducing both bosonic and fermionic (non)central extensions. We study the Inonu-Wigner contraction of the extended psu(2,2|4) under the Penrose limit to obtain the most general consistent extension of the plane-wave superalgebra and compare these extensions with the possible BPS (flat or spherical) brane configurations in the plane-wave background. We give an explicit realization of some of these extensions in terms of the Tiny Graviton Matrix Theory (TGMT)[hep-th/0406214] which is the 0+1 dimensional gauge theory conjectured to describe the DLCQ of strings on the AdS_5 x S^5 and/or the plane-wave background.

description: This paper analyses the potential employment effects of foreign direct investment in the Swiss services industry. First, the theoretical analysis considers the consequences on domestic employment resulting from the specific characteristics of services compared with those of industrial goods. It is demonstrated that conventional research in this field systematically ignores important factors which influence domestic employment. We point out that, not only the degree of tradability of services, but also the mobility of consumers and producers, as well as the motives underlying the decisions for foreign investment have a crucial influence on the consequences to be expected for the domestic labour market. Second, an initial attempt was undertaken to empirically test our theoretical framework. It is shown for the Swiss tourism industry that the obtained results are to a high extent consistent with those predicted. Dieser Beitrag untersucht die potentiellen Beschäftigungseffekte von Direktinvestitionen der Unternehmen des Dienstleistungssektors für die Schweiz. In einer theoretischen Perspektive werden zunächst die Konsequenzen der Besonderheiten von Dienstleistungsgütern gegenüber Industriegütern für die heimischen Beschäftigungseffekte analysiert. Hierbei zeigt sich, dass die bisherige Forschung wesentliche Determinanten systematisch ausklammert. Denn nicht allein der Grad der Handelbarkeit der Dienstleistungsgüter, sondern gleichfalls die Mobilität der Konsumenten und Produzenten sowie die den Auslandsinvestitionen zugrunde liegenden Motive sind zentral für die Eruierung der zu erwartenden Auswirkungen auf den inländischen Arbeitsmarkt. Eine erste empirische Überprüfung unseres Ansatzes bestätigt schließlich für die schweizerische Tourismusbranche die theoretisch vermuteten Zusammenhänge.

Unobserved Firm Heterogeneity and the Size - Exports Nexus: Evidence from German Panel Data

subject: establishment panel data
subject: fractional logit regression

description: This paper starts from the stylized fact that firm size and exporting tends to be positively related. Using large sets of establishment panel data for three different industries from official statistics evidence is presented that the familiar picture of an export/sales ratio that ceteris paribus increases (at a decreasing rate) with firm size vanishes if unobserved firm heterogeneity is controlled for in a fixed effects fractional logit regression model. This finding is well in line with the fact that many small firms are "hidden export champions". Das Papier geht von dem stilisierten Faktum aus, dass Unternehmensgröße und Exportorientierung positiv miteinander zusammenhängen. Auf der Grundlage eines umfangreichen Betriebsdatensatzes der amtlichen Statistik für drei Zweige des Verarbeitenden Gewerbes wird dieser Zusammenhang in einem fraktionalen logit Regressionsmodell mit fixed effects näher untersucht. Dabei verschwindet das gewohnte Bild einer degressiv mit der Betriebsgröße steigenden Exportquote, wenn die unbeobachtete Heterogenität der Betriebe kontrolliert wird. Dies Ergebnis stimmt gut mit der Tatsache überein, dass viele kleinere Firmen als "hidden export champions" anzusehen sind.

description: Single photon avalanche diode arrays can provide both the spatial and temporal information of each detected photon. We present here the characterization of entangled light with a sensor specifically designed for quantum imaging applications. The sensors is time-tagging each detection events at the pixel level with sub-nanosecond accuracy, within frames of 50 ns. The spatial correlations between any number of detections in a defined temporal window can thus be directly extracted from the data. We show the ability of the sensor to characterize space-momentum entangled photon pairs emitted by spontaneous parametric downconversion. Their entanglement is demonstrated by violating an EPR-type inequality.

Europaische Integration und raumliche Entwicklungsprozesse: Wo bleibt die nationale Ebene?

description: Im Zuge der europäischen Integration haben die nationalen Regierungen Kompetenzen an europäische Institutionen abgegeben. Die Folge ist, daß die ökonomische Entwicklung in der EU mehr und mehr von wirtschaftsräumlichen Faktoren anstatt von administrativen nationalen Unterschieden bestimmt wird. Der gestiegenen Bedeutung wirtschaftsräumlicher Faktoren müßte durch mehr gesetzgebende und administrative Kompetenzen regionaler Gebietskörperschaften entsprochen werden. Regionale Gebietskörperschaften in der EU sind in den letzten Jahren allerdings kaum substantiell gestärkt worden. Die Gestaltungskraft der nationalen Ebene ist nach wie vor groß, und es ist noch ein langer Weg, bis ein "Europa der Regionen" entstanden sein wird. In the course of European integration national states have lost regulative competence to European authorities. Consequently, regional factors have gained in importance for economic development. The location of firms and persons depends more and more on regional factors rather than national differences. The increased importance of regional factors requires a corresponding increase in the legislative and administrative power of regional authorities. However, regional authorities in Europe have not been strengthened substantially in recent years. The power of national authorities is still great and there is still a long way to go to a "Europe of Regions".

description: We present the anisotropic clustering of emission line galaxies (ELGs) from the Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 16 (DR16). Our sample is composed of 173,736 ELGs covering an area of 1170 deg$^2$ over the redshift range $0.6 \leq z \leq 1.1$. We use the Convolution Lagrangian Perturbation Theory in addition to the Gaussian Streaming Redshift-Space Distortions to model the Legendre multipoles of the anisotropic correlation function. We show that the eBOSS ELG correlation function measurement is affected by the contribution of a radial integral constraint that needs to be modelled to avoid biased results. To mitigate the effect from unknown angular systematics, we adopt a modified correlation function estimator that cancels out the angular modes from the clustering. At the effective redshift, $z_{\rm eff}=0.85$, including statistical and systematical uncertainties, we measure the linear growth rate of structure $fσ_8(z_{\rm eff}) = 0.35\pm0.10$, the Hubble distance $D_H(z_{\rm eff})/r_{\rm drag} = 19.1^{+1.9}_{-2.1}$ and the comoving angular diameter distance $D_M(z_{\rm eff})/r_{\rm drag} = 19.9\pm1.0$. These results are in agreement with the Fourier space analysis, leading to consensus values of: $fσ_8(z_{\rm eff}) = 0.315\pm0.095$, $D_H(z_{\rm eff})/r_{\rm drag} = 19.6^{+2.2}_{-2.1}$ and $D_M(z_{\rm eff})/r_{\rm drag} = 19.5\pm1.0$, consistent with $Λ$CDM model predictions with Planck parameters.

description: We present an unquenched calculation of the quark propagator in Landau gauge with 2+1 flavors of dynamical quarks. We use configurations generated with an improved staggered (``Asqtad'') action by the MILC collaboration. This quark action has been seen to have excellent rotational symmetry and scaling properties in the quenched quark propagator. Quenched and dynamical calculations are performed on a $20^3\times 64$ lattice with a nominal lattice spacing of $a = 0.125$ fm. The matched quenched and dynamical lattices allow us to investigate the relatively subtle sea quark effects, and even in the quenched case the physical volume of these lattices gives access to lower momenta than our previous study. We calculate the quark mass function and renormalization function for a variety of valence and sea quark masses.

description: Reflection is a critical aspect of the learning process. However, educational games tend to focus on supporting learning concepts rather than supporting reflection. While reflection occurs in educational games, the educational game design and research community can benefit from more knowledge of how to facilitate player reflection through game design. In this paper, we examine educational programming games and analyze how reflection is currently supported. We find that current approaches prioritize accuracy over the individual learning process and often only support reflection post-gameplay. Our analysis identifies common reflective features, and we develop a set of open areas for future work. We discuss these promising directions towards engaging the community in developing more mechanics for reflection in educational games.

It is shown that the vacuum evolves as a time dependent $SU(2)$ squezed state. The time dependent entanglement entropy is calculated and it has the same form of the Page curve of Black Hole formation and evaporation.

Therefore some proofs of new results are only sketched or omitted if their completing seems to be not too difficult for readers. In particular, we show as the Hosszú-Gluskin Theorem can be used for evaluation how many different $n$-ary groups (up to isomorphism) exist on some small sets. Moreover, we sketch as the mentioned theorem can be also used for investigation of $\mathcal{Q}$-independent subsets of semiabelian $n$-ary groups for some special families $\mathcal{Q}$ of mappings.

description: On 2012 August 2, two CMEs (CME-1 and CME-2) erupted from the west limb of the Sun as viewed from Earth, and were observed in images from the white light coronagraphs on the SOHO and STEREO spacecraft. These events were also observed by the Very Large Array (VLA), which was monitoring the Sun at radio wavelengths, allowing time-dependent Faraday rotation observations to be made of both events. We use the white-light imaging and radio data to model the 3-D field geometry of both CMEs, assuming a magnetic flux rope geometry. For CME-2, we also consider 1 au in situ field measurements in the analysis, as this CME hits STEREO-A on August~6, making this the first CME with observational constraints from stereoscopic coronal imaging, radio Faraday rotation, and in situ plasma measurements combined. The imaging and in situ observations of CME-2 provide two clear predictions for the radio data; namely that VLA should observe positive rotation measures (RMs) when the radio line of sight first encounters the CME, and that the sign should reverse to negative within a couple hours. The initial positive RMs are in fact observed. The expected sign reversal is not, but the VLA data unfortunately end too soon to be sure of the significance of this discrepancy. We interpret an RM increase prior to the expected occultation time of the CME as a signature of a sheath region of deflected field ahead of the CME itself.

Iron abundances derived from RR Lyrae light curves and low-dispersion spectroscopy

description: With the aid of the All Sky Automated Survey (ASAS) database on the Galactic field, we compare the iron abundances of fundamental mode RR Lyrae stars derived from the Fourier parameters with those obtained from low-dispersion spectroscopy. We show from a set of 79 stars, distinct from the original calibrating sample of the Fourier method and selected without quality control, that almost all discrepant estimates are the results of some defects or peculiarities either in the photometry or in the spectroscopy. Omitting objects deviating by more than 0.4dex, the remaining subsample of 64 stars yields Fourier abundances that fit the spectroscopic ones with a standard deviation of 0.20dex. Other, more stringent selection criteria and different Fourier decompositions lead to smaller subsamples and concomitant better agreement, down to 0.16dex standard deviation. Except perhaps for two variables among the 163 stars, comprised of the ASAS variables and those of the original calibrating set of the Fourier method, all discrepant values can be accounted for by observational noise and insufficient data coverage. We suggest that the agreement can be further improved when new, more accurate spectroscopic data become available for a test with the best photometric data. As a by-product of this analysis, we also compute revised periods and select Blazhko variables.

description: We present the discovery of seven quasars at z>5.7, selected from ~2000 deg^2 of multicolor imaging data of the Sloan Digital Sky Survey (SDSS). The new quasars have redshifts z from 5.79 to 6.13. Five are selected as part of a complete flux-limited sample in the SDSS Northern Galactic Cap; two have larger photometric errors and are not part of the complete sample. One of the new quasars, SDSS J1335+3533 (z=5.93), exhibits no emission lines; the 3-sigma limit on the rest-frame equivalent width of Ly alpha+NV line is 5 A. It is the highest redshift lineless quasar known, and could be a gravitational lensed galaxy, a BL Lac object or a new type of quasar. Two new z>6 quasars, SDSS 1250+3130 (z=6.13) and SDSS J1137+3549 (z=6.01), show deep Gunn-Peterson absorption gaps in Ly alpha. These gaps are narrower the complete Gunn-Peterson absorption troughs observed among quasars at z>6.2 and do not have complete Ly beta absorption.

The effect of a solar flare on chromospheric oscillations

description: Oscillations in the solar atmosphere have long been observed in quiet conditions, and increasingly also in data taken during solar flares. The chromosphere is known for its 3-minute signals, which are particularly strong over sunspot umbrae. These signals are thought to be driven by photospheric disturbances and their periods determined by the chromosphere's acoustic cut-off frequency. A small number of observations have shown the chromospheric 3-minute signals to be affected by energetic events such as solar flares, however the link between flare activity and these oscillatory signals remains unclear. In this work we present evidence of changes to the oscillatory structure of the chromosphere over a sunspot which occurs during the impulsive phase of an M1 flare. Using imaging data from the CRISP instrument across the H$α$ and Ca II 8542 Å spectral lines, we employed a method of fitting models to power spectra to produce maps of areas where there is evidence of oscillatory signals above a red noise background. Comparing results taken before and after the impulsive phase of the flare, we found that the oscillatory signals taken after the start of the flare differ in two ways: the locations of oscillatory signals had changed and the typical periods of the oscillations had tended to increase (in some cases increasing from $\lt$100s to $\sim$200s). Both of these results can be explained by a restructuring of the magnetic field in the chromosphere during the flare activity, which is backed up by images of coronal loops showing clear changes to magnetic connectivity. These results represent one of the many ways that active regions can be affected by solar flare events.
Optical detection of the 1.1-day variability at the white dwarf GD 394 with TESS

description: Recent discoveries have demonstrated that planetary systems routinely survive the post-main sequence evolution of their host stars, leaving the resulting white dwarf with a rich circumsteller environment. Among the most intriguing of such hosts is the hot white dwarf GD 394, exhibiting a unique $1.150\pm0.003$ d flux variation detected in Extreme Ultraviolet Explorer (EUVE) observations in the mid 1990s. The variation has eluded a satisfactory explanation, but hypotheses include channeled accretion producing a dark spot of metals, occultation by a gas cloud from an evaporating planet, or heating from a flux tube produced by an orbiting iron-cored planetesimal. We present observations obtained with the Transiting Exoplanet Survey Satellite (TESS) of GD 394. The space-based optical photometry demonstrates a $0.12\pm0.01$ % flux variation with a period of $1.146\pm 0.001$ d, consistent with the EUVE period and the first re-detection of the flux variation outside of the extreme ultraviolet. We describe the analysis of the TESS light curve and measurement of the optical variation, and discuss the implications of our results for the various physical explanations put forward for the variability of GD 394.

Prediction for Quark Mixing from Universal Quark and Lepton Mass Matrices with Flavor 2 3 Symmetry

description: We propose a mass matrix model that gives a unified description of quark and lepton with the same texture form based on a flavor 2 3 symmetry. The model is in contrast with the conventional picture that the mass matrix forms in the quark sector will take somewhat different structures from those in the lepton sector. By investigating possible types of assignment for masses, we find that our quark mass matrices can lead to small CKM quark mixings which are consistent with experimental values. We also find some phase-parameter-independent relations among CKM quark mixing matrix elements.

description: This paper contains the results of research on the determination of groups of students who have difficulty learning in geometry material of three-dimensional space. Determination of student groups is done by cluster analysis method based on variables of learning difficulties. The sample used was 53 students of class XI of SMA Negeri 1 Bendahara, Aceh Tamiang District. To see the similarity between respondents who will be grouped into one group, the Euclidean distance measure is used by considering the score of each variable of learning difficulties. By using average linkage, the results show that there are 3 groups of students who have difficulty learning geometry in the three dimensional space, low difficulty cluster 1 as many as 27 students which are characterized by the lowest average value in variable 3 (visual-motor association), variable 4 (perseveration) , variable 5 (difficulty recognizing and understanding symbols) and variable 6 (difficulties in language and reading), cluster 2 moderate difficulties as many as 22 students which are indicated by the lowest average value on variable 1 (spatial relationship disorder) and variable 2 (perception abnormality visual), 4 high difficulty clusters are 4 students which are marked by the highest average score for each variable. By using ward, it was found that there were 3 groups of students who had difficulty learning geometry in the three dimensional space, low difficulty, cluster 1 as many as 26 students which was indicated by the lowest average value in variable 3 (visual-motor association), variable 5 (difficulty recognizing and understand the symbol) and variable 6 (difficulty in language and reading); cluster 2, high difficulty as many as 17 students which is indicated by the highest average value in variable 3 (visual-motor association), variable 4 (perseveration) and variable 6 (difficulty in language and reading), and cluster 3, moderate difficulty as many as 10 students marked by the lowest average value in variable 4 (perseveration).
