description: In the present investigation, effects of Ramalina capitata acetone extract on micronucleus distribution on human lymphocytes, on cholinesterase activity and antioxidant activity (by the CUPRAC method) were examined, for the first time as well as its HPLC profile. Additionally, total phenolic compounds (TPC), antioxidant properties (estimated via DPPH, ABTS and TRP assays) and antibacterial activity were determined. The predominant phenolic compounds in this extract were evernic, everninic and obtusatic acids. Acetone extract of R. capitata at concentration of 2 μg mL-1 decreased a frequency of micronuclei (MN) for 14.8 %. The extract reduces the concentration of DPPH and ABTS radicals for 21.2 and 36.1 % (respectively). Values for total reducing power (TRP) and cupric reducing capacity (CUPRAC) were 0.4624 ± 0.1064 μg ascorbic acid equivalents (AAE) per mg of dry extract, and 6.1176 ± 0.2964 μg Trolox equivalents (TE) per mg of dry extract, respectively. The total phenol content was 670.6376 ± 66.554 μg galic acid equivalents (GAE) per mg of dry extract. Tested extract at concentration of 2 mg mL-1 exhibited inhibition effect (5.2 %) on pooled human serum cholinesterase. The antimicrobial assay showed that acetone extract had inhibition effect towards Gram-positive strains. The results of manifested antioxidant activity, reducing the number of micronuclei in human lymphocytes, and antibacterial activity recommends R. capitata extract for further in vivo studies.

description: This study uses aggregated provincial level data from 1979 to 2000 to estimate crop-specific production functions and identifies the sources of production growth for wheat, corn, soybean, rapeseeds, and cotton in China. The results show that fertilizer, pesticide, seeds, production specification, weather, and R&D are important determinants of crop yields. The land, fertilizer, and R&D are major contributors to production growth during the study period.
Heterogeneity in political decision-making : the nature, sources, extent, dynamics, and consequences of interpersonal differences in coefficient strength
Creators: name: Fournier, Patrick

Year: 2009

description: There is mounting evidence that the public's political decisional processes are heterogeneous (Rivers, 1988; Sniderman, Brody & Tetlock, 1991; and Johnston, Blais, Gidengil & Nevitte, 1996). All citizens do not reason the same way about politics: they rely on different considerations, or they give different weights to similar considerations. However, our understanding of this phenomenon remains sketchy, in many regards. I address the conceptual and empirical ambiguity by exploring the nature, the sources, the extent, the consequences, and the campaign dynamics of interpersonal heterogeneity in political decision-making. The analysis relies on Canadian and American public opinion survey data. The evidence reveals that heterogeneity is a very important phenomenon. Relationships between dependent and explanatory variables are rarely stable and consistent across the entire population. Most political decisions (especially the more common ones) and most independent variables exhibit interpersonal diversity in coefficient strength. Hypothesis-testing and explanationbuilding can be led astray if researchers limit their analyses to the whole citizenry. Normatively, heterogeneity is responsible for individual and aggregate deviations from enlightened preferences. Heterogeneity, however, is a very complex phenomenon. One can not deal with it in any simple way. A researcher can not simply capture it, take it into account, and move on to other concerns. Heterogeneity permeates through our models of political behaviour in significant, pervasive and perplexing ways. This research raises concerns about the complexity of political behaviour and our ability to understand citizens, campaigns, elections, and democracy. The world is not a simple, straightforward and easily comprehensible subject. It is much more intricate and difficult to grasp than we currently believe. In order to understand reality, our approaches, theories, and models need to be as complex and multidimensional as reality. Striving for oversimplification can only lead to misconceptions and fallacies.

Μία από τις πολλές διαφορετικές περιπτώσεις οι οποίες επηρεάζουν τον ανταγωνισμό σε μια αγορά και θεωρούνται ως κατάχρηση της δεσπόζουσας θέσης από μια επιχείρηση σύμφωνα με το Άρθρο 102 της Συνθήκης της Λειτουργίας της ΕΕ (ΣΛΕΕ) είναι η συμπίεση του περιθωρίου κέρδους/συμπίεση τιμών, η οποία στο εξής συχνά θα αναφέρεται απλά ως συμπίεση περιθωρίου ή με το διεθνή ορισμό της, ως Margin Squeeze (ή Price Squeeze).

Στην πράξη, παρατηρείται όταν μια τέτοια επιχείρηση, χρεώνει τις υπηρεσίες της στην ανάντη αγορά (τιμή χονδρικής χρέωσης προϊόντος) σε τιμή που, συγκρινόμενη με την τιμή που χρεώνει στην κατάντη αγορά (τιμή λιανικής χρέωσης προϊόντος), δεν επιτρέπει ακόμη και σε έναν εξίσου αποτελεσματικό ανταγωνιστή να έχει εμπορικό κέρδος με κάποια διάρκεια έτσι ώστε να μπορεί να επιβιώσει. Σκοπός της παρούσας διπλωματικής εργασίας είναι να αναλύσει και να συγκρίνει πως αντιμετωπίζεται η συμπίεση του περιθωρίου κέρδους ως κατάχρηση της δεσπόζουσας θέσης τόσο στην Ευρωπαϊκή Ένωση (ΕΕ) όσο και στις Ηνωμένες Πολιτείες Αμερικής (ΗΠΑ).

description: The first complete far-infrared spectrum (43-197um) of the Seyfert 2 galaxy NGC 1068 as observed with the LWS onboard ISO is reported. In addition to the expected ionic fine structure emission lines, the OH rotational lines at 79, 119 and 163um were all detected in emission. The line intensities were modelled together with ISO SWS and optical and UV line intensities from the literature, considering two independent emission components: the AGN component and the starburst component in the circumnuclear ring of 3 kpc in size. Using the UV to mid-IR emission line spectrum to constrain the nuclear ionizing continuum, we have confirmed previous results: a canonical power-law ionizing spectrum is a poorer fit than one with a deep absorption trough, while the presence of a big blue bump is ruled out. Based on starburst synthesis models, we were able to fit the mid- and far-infrared fine-structure line emission, with a low ionization parameter (logU=-3.5) and low densities (n=100 cm^-3). Combining AGN and starburst components, we succeeded in modeling the overall UV to far-IR atomic spectrum of NGC1068, reproducing the line fluxes to within a factor 2.0 on average with a standard deviation of 1.3 and the overall continuum as the sum of the contribution of the thermal dust emission in the ionized and neutral components. TheOH 119 um emission indicates that the line is collisionally excited and arises in a warm and dense region. The OH emission has been modeled using spherically symmetric, non-local, non-LTE radiative transfer models. The models indicate that the bulk of the emission arises from the nuclear region, although some extended contribution from the starburst is not ruled out. The OH abundance in the nuclear region is expected to be $\sim10^{-5}$, characteristic of X-ray dominated regions.

description: It has been shown that a Hamiltonian with an unbroken $\cP\cT$ symmetry also possesses a hidden symmetry that is represented by the linear operator $\cC$. This symmetry operator $\cC$ guarantees that the Hamiltonian acts on a Hilbert space with an inner product that is both positive definite and conserved in time, thereby ensuring that the Hamiltonian can be used to define a unitary theory of quantum mechanics. In this paper it is shown how to construct the operator $\cC$ for the $\cP\cT$-symmetric square well using perturbative techniques.

description: This study aims to comparing the effect of short intermittent training "running" (ITr) and intermittent training "running-strength" (ITr-s) on aerobic-anaerobic performances: the maximum oxygen consumption (VO 2max), maximum aerobic speed (MAS) and explosive strength of lower limbs of handball players. For this purpose, we used the experimental method on an intentional sample of (12) male handball players subdivided into twohomogeneous experimental groups from Nadjm Djemila -Setif- for 6 weeks of training, and for data collection, we used the physical tests (Yo-Yo test and Sargent Jump test). After collecting the results and having treated them statistically, we conclude that the two intermittent training had almost the same effect on MAS and VO 2max, while the effect of short ITr-s on explosive strength of the lower limbs was significant compared to the ITr, the study recommends using the ITr-s in the physical preparation process at the beginning of season in order to develop effectively both aerobic/anaerobicperformances.

Το ανταγωνιστικό πλεονέκτημα είναι ζωτικής σημασίας στοιχείο για τις σύγχρονες επιχειρήσεις, οι οποίες καλούνται να επιβιώσουν σε ένα περιβάλλον έντονων ανταγωνιστικών πιέσεων. Η σημαντικότητα της εν λόγω μελέτης έγκειται στο ότι οι αντίστοιχες έρευνες, που έχουν διεξαχθεί στην Ελλάδα γύρω από την αξιοποίηση του branding ως στοιχείου της στρατηγικής μάρκετινγκ των επιχειρήσεων, είναι ελάχιστες. Επομένως, καλύπτεται ένα μεγάλο βιβλιογραφικό κενό. Το ζήτημα πραγμάτευσης της εν λόγω μελέτης προσεγγίζεται διττά, δηλαδή μέσω βιβλιογραφικής ανασκόπησης και μέσω πρωτογενούς ποσοτικής έρευνας. Η πρωτογενής έρευνα απευθύνθηκε σε 152 εργαζομένους, στελέχη ή ιδιοκτήτες επιχειρήσεων, οι οποίοι συμπλήρωσαν ένα πλήρως δομημένο ερωτηματολόγιο, που απαρτιζόταν από ερωτήσεις κλειστού τύπου. Από το ερωτηματολόγιο διαμορφώθηκαν οι δύο εξεταζόμενες μεταβλητές· η αξιοποίηση του branding και τα οφέλη αυτού. Εν τέλει, προέκυψε ότι οι επιχειρήσεις αξιοποιούν το μάρκετινγκ και το branding σε μέτριο προς ικανοποιητικό επίπεδο. Τα αποκομιζόμενα οφέλη από το branding είναι πολύ ικανοποιητικά και τα βασικότερα εξ αυτών είναι η διαμόρφωση της εικόνας και φήμης της εταιρείας, η δημοτικότητα αυτής και η ενίσχυση του ανταγωνιστικού της πλεονεκτήματος. Επίσης, εντοπίστηκε θετική και στατιστικά σημαντική συσχέτιση μεταξύ της αξιοποίησης του branding και των αποκομιζόμενων ωφελειών.

description: This article reports the results from a series of laboratory auction markets in which consumers bid on meat characteristics. The characteristics examined include meat traceability (i.e., the ability to trace the retail meat back to the farm or animal or origin), transparency (e.g., knowing that the meat was produced without growth hormones, or knowing the animal was humanely treated), and extra assurances (e.g., extra meat safety assurances). This laboratory study provides non-hypothetical bid data on U. S. consumer preferences for traceability, transparency, and assurances (TTA) in red meat at a time when the U.S. currently lags other countries in development of TTA meat systems. Our results suggest that U.S. consumers would be willing to pay for such TTA meat characteristics, and the magnitude of the consumer bids suggest a likely profitable market for development of U.S. TTA systems.

description: Sodium metabisulfite (Na-MBS) is a disinfectant and preservative agent. Some organ including testicle would be in danger in the case of Na-MBS consumption. Curcumin (CUR) is the constituent of turmeric with protective properties. The effect of CUR on testicles in rats exposed to Na-MBS evaluated using stereological methods. Sprague-Dawley rats were divided into eight groups. The rats in groups I to VIII received the following respec- tively: distilled water, CUR (100 mg/kg/day), low (0.7 mg/kg/day: acceptable daily intake), intermediate (7 mg/ kg/day), and high (70 mg/kg/day) doses of Na-MBS, and low, intermediate, and high doses of Na-MBS plus CUR. After 7 weeks, the testicles were analyzed. The volume of seminiferous tubule, tubular epithelium and tubule length reduced (25-40 %) on average in the rats that received intermediate and high doses of Na-MBS, while the connective tissue volume increased (15-20 %) in both groups (P<0.01). Besides, 19-36 % and 41-57 % of the cells (spermatogonia types A and B, spermatids, Sertoli and Leydig) were lost in the rats that received intermediate and high doses of Na-MBS respectively in comparison to the control groups. Nonetheless, all the above-mentioned alterations ameliorated drastically in the rats that received Na-MBS plus CUR compared to those exposed to Na- MBS without CUR therapy (P<0.01). The acceptable daily intake of Na-MBS for 7 weeks did not affect on testic- ular parameters. CUR (100 mg/kg/day) could prevent structural impairments of testicles in the rats induced by Na-MBS (7 and 70 mg/kg/day).

description: MiR-429 functions as a tumor suppressor and has been observed in multiple types of cancer, but the effects and mechanisms of miR-429 in osteosarcoma are poorly understood. This study is performed to evaluate the functions of miR-429 in the progression of osteosarcoma. Firstly, the miR-429 expression in osteosarcoma tissues and oste- osarcoma cells was detected using real time PCR, and the relationship between miR-429 expression and overall survival of osteosarcoma was analyzed. Secondly, the effects of miR-429 on the migration, invasion, proliferation and apoptosis of osteosarcoma cells were evaluated using transwell assay, wound-healing assay, CCK-8 assay and flow cytometry, respectively. Proteins related to epithelial-mesenchymal transition (EMT), E-cadherin, Vimentin, N-cadherin and Snail, were also detected using Western blot. Finally, the target gene of miR-429 in osteosarcoma was predicted and verified using dual luciferase assay and the expression correlation between them was analyzed using Pearson’s correlation. MiR-429 was down-regulated in osteosarcoma tissues and osteosarcoma cells; the expression level of miR-429 was associated with the prognosis of osteosarcoma. High level of miR-429 in osteo- sarcoma cells significantly suppressed the migration, invasion and proliferation of cells but induced cells apopto- sis. Furthermore, high level of miR-429 in osteosarcoma cells obviously increased the expression of E-cadherin protein but decreased the expression of Vimentin, N-Cadherin and Snail proteins. EMT inducer ZEB1 was the target gene of miR-429 and the expression of ZEB1 was negatively related to the miR-429 expression in osteosar- coma. In conclusion, miR-429 may functions as a tumor suppressor and be down-regulated in osteosarcoma. MiR- 429 may suppress the progression and metastasis of osteosarcoma by down-regulating the ZEB1 expression.

description: We review the physics underlying Meyer's conjecture of how macroscopic-scale twist and bend conspire within the Frank-Oseen elasticity theory of nematics to create a heliconical arrangement of the uniaxial, apolar nematic director, the so-called "twist bend nematic" $\rm N_{TB}$. We show that since 2011 a second, lower-temperature nematic phase observed in odd methylene-linked cyanobiphenyl dimers discovered by Toriumi and called $\rm N_X$, has been incorrectly identified as $\rm N_{TB}$. Moreover, as more quantitative data on the $\rm N_X$ emerged, Meyer's simple prediction has been distorted to accommodate those findings. In fact, the molecular organization in the $\rm N_X$ conforms to the $\rm N_{PT}$ phase, a polar, twisted arrangement of nonlinear mesogens advanced in 2016. The attributes of the $\rm N_{PT}$ are summarized and differentiated from those of the $\rm N_{TB}$ in an effort to contribute to a better understanding of the $\rm N_X$ phase and, equally important, to encourage researchers to continue to search for a liquid crystal that exhibits Meyer's pioneering theoretical suggestion, namely that form-chirality can exist in simple nematics composed of achiral molecules.

description: The data sciences revolution is poised to transform the way photonic systems are simulated and designed. Photonics are in many ways an ideal substrate for machine learning: the objective of much of computational electromagnetics is the capture of non-linear relationships in high dimensional spaces, which is the core strength of neural networks. Additionally, the mainstream availability of Maxwell solvers makes the training and evaluation of neural networks broadly accessible and tailorable to specific problems. In this Review, we will show how deep neural networks, configured as discriminative networks, can learn from training sets and operate as high-speed surrogate electromagnetic solvers. We will also examine how deep generative networks can learn geometric features in device distributions and even be configured to serve as robust global optimizers. Fundamental data sciences concepts framed within the context of photonics will also be discussed, including the network training process, delineation of different network classes and architectures, and dimensionality reduction.

description: This study explores the differences in pollution control performances of industrial enterprises with various ownerships in China - State owned (SOE), collectively or community owned (COE), privately owned (POE), foreign directly invested (FDI) companies as well as joint ventures. A survey was conducted of approximately 1000 industrial firms in three provinces in China, which collects the detailed firm-level information in the year of 1999. Personal interviews of enterprises managers were also conducted in these samples, and subjective information was collected. Analyses have been performed on the differences in receiving and reacting to environmental regulatory enforcement, community pressure, environmental services, and internal environmental management among different ownerships. The determinants of the industrial pollution emissions in China are identified in the econometrical analyses. The results show that FDI and COE have better environmental performances, while SOEs and the POEs in China are the worst.

Η θαλάσσια περιβαλλοντική νομοθεσία γίνεται όλο και πιο αυστηρή τα τελευταία χρόνια, δηλαδή από τότε που έγινε εισαγωγή των κανονισμών της MARPOL 73/78. Η διεθνής σύμβαση MARPOL 73/78, περιλαμβάνει αυστηρούς κανόνες, οι οποίοι αφορούν την απόρριψη χημικών καταλοίπων, λυμάτων και απορριμμάτων, υπό την προϋπόθεση ότι πληρούνται ορισμένες προϋποθέσεις. Η απελευθέρωση χημικών ουσιών στο θαλάσσιο περιβάλλον συμβαίνει είτε με ακούσια ατυχήματα, είτε με απόρριψη χημικών αποβλήτων που προκύπτουν από εργασίες πλύσης δεξαμενών δεξαμενόπλοιων που μεταφέρουν χημικά. Η απόρριψη λυμάτων και απορριμμάτων αφορά κάθε τύπο πλοίου. Στην παρούσα διπλωματική εργασία, θα αναφερθούν αρχικά τα σημαντικότερα ατυχήματα πλοίων που έλαβαν χώρα από το 1976 μέχρι και το 2002 και ουσιαστικά δημιούργησαν την ανάγκη της άμβλυνσης των μέτρων προστασίας του θαλάσσιου περιβάλλοντος, θεσπίζοντας τη Διεθνή Σύμβαση MARPOL 73/78. Εν συνεχεία, θα γίνει μία γενική περιγραφή των έξι Παραρτημάτων της σύμβασης, παρουσιάζοντας τι αφορά το καθένα και πότε τέθηκαν σε ισχύ. Επιπλέον, θα αναλυθούν εκτενέστερα οι συγκεκριμένες απαιτήσεις και οι περιορισμοί που αφορούν το κάθε ξεχωριστό Παράρτημα, δίνοντας έμφαση στις κατ’ ελάχιστες τιμές που πρέπει να πληρούνται σε θέματα όπως απόσταση από την ακτή, ταχύτητα πλοίου κ.ά. Τέλος, θα γίνει αναφορά στο νομοθετικό δίκαιο που έχει τεθεί σε ισχύ σε ευρωπαϊκό και πανελλαδικό επίπεδο και σε κάποιες επιπλέον διεθνής συμβάσεις που έχουν ενσωματωθεί στο νομοθετικό πλαίσιο του International Maritime Organization (IMO). Όλα τα παραπάνω θα συμπληρωθούν από τα γενικά συμπεράσματα και τις πιθανές μελλοντικές εργασίες που μπορούν να εκπονηθούν γύρω από αυτό το αντικείμενο.

The central thesis of the article is the idea that communication assistance, contrary to the understanding of assistance established by the empowerment movement, is a complex activity that does not only require an appropriate attitude, but also specific technical and methodical know-how. The article presents a proposal for the systematization of assistive conversation strategies and uses examples to transfer them to the field of AAC.
description: In dem Beitrag werden entlang nationaler und internationaler Forschungsbefunde Herausforderungen in der Assistenz von Kindern, Jugendlichen und Erwachsenen, die aufgrund einer Beeinträchtigung mit alternativen und ergänzenden Kommunikationshilfsmitteln kom­munizieren, skizziert. Zentrale These des Beitrags ist der Gedanke, dass es sich bei Kommunikations-Assistenz entgegen dem durch die Empowerment-Bewegung etablierten Assistenzverständnis um eine hoch komplexe Tätigkeit handelt, die nicht nur eine ent­sprechende Haltung, sondern auch spezifisches fachliches und methodisches Know-How erfordert. Es wird ein Vorschlag zur Systematisierung assistierender Gesprächsstrategien vorgestellt und auf das Feld der Unterstützten Kommunikation anhand von exemplarischen Beispielen übertragen.

description: By observing the near-infrared spectrum of the quasar PG 1116+215 at z = 0.176 and combining with the HST/FOS spectrum, we obtained the relative strengths of three permitted OI lines ({lambda}1304, {lambda}8446, and {lambda}11287) in a quasar for the first time. The photon flux ratios of the OI lines of the quasar were compared with those previously measured in a Seyfert 1 and six narrow-line Seyfert 1s. No significant differences were found in the OI line flux ratios between the quasar and the other Seyferts, suggesting that the gas density in the OI and FeII line-emitting regions in the quasar is of the same order as those in low-luminosity AGNs. It was also found that the line width of OI {lambda}11287 is significantly narrower than that of Ly{alpha}, which is consistent with OI and FeII emission occurring in the partly ionized regions at the outermost portion of the broad-line region where velocities are small.

description: Breast cancer is the most prevalent cancer that affects women all over the world. Early detection and treatment of breast cancer could decline the mortality rate. Some issues such as technical reasons, which related to imaging quality and human error, increase misdiagnosis of breast cancer by radiologists. Computer-aided detection systems (CADs) are developed to overcome these restrictions and have been studied in many imaging modalities for breast cancer detection in recent years. The CAD systems improve radiologists’ performance in finding and discriminating between the normal and abnormal tissues. These procedures are performed only as a double reader but the absolute decisions are still made by the radiologist. In this study, the recent CAD systems for breast cancer detection on different modalities such as mammography, ultrasound, MRI, and biopsy histopathological images are introduced. The foundation of CAD systems generally consist of four stages: Pre-processing, Segmentation, Feature extraction, and Classification. The approaches which applied to design different stages of CAD system are summarised. Advantages and disadvantages of different segmentation, feature extraction and classification techniques are listed. In addition, the impact of imbalanced datasets in classification outcomes and appropriate methods to solve these issues are discussed. As well as, performance evaluation metrics for various stages of breast cancer detection CAD systems are reviewed.

description: Τα τελευταία έτη, παρουσιάζονται ραγδαίες εξελίξεις στον τομέα της τεχνολογίας, οι οποίες επηρεάζουν άμεσα την καθημερινότητα όλων των πολιτών, με το διαδίκτυο και τα ευρύτερα ψηφιακά μέσα να έχουν λάβει μια μόνιμη θέση στην ζωή όλων. Το ηλεκτρονικό εμπόριο αποτελεί μια από τις πιο πρόσφατες χρήσεις του διαδικτύου, το οποίο εξελίσσεται και αυξάνεται μέρα με την μέρα. Στον εμπόριο αυτό δεν άργησαν να κάνουν και την εμφάνιση τους τα παραφαρμακευτικά προϊόντα (προϊόντα πρώτων βοηθειών, συμπληρώματα διατροφής κ.α.) μέσω των διαδικτυακών φαρμακείων. Ο στόχος της παρούσας εργασίας είναι η ορθή ενημέρωση σχετικά με τα καταστήματα τα οποία λειτουργούν μέσω του διαδικτύου, και πιο συγκεκριμένα για την διακίνηση των παραφαρμακευτικών προϊόντων μέσω αυτού του καναλιού διανομής. Αναφέρονται οι απαραίτητες προϋποθέσεις που χρειάζεται να τηρούνται προκειμένου να μπορεί να πραγματοποιηθεί η πώληση των παραφαρμακευτικών προϊόντων μέσω του διαδικτύου τόσο στην Ελλάδα όσο και σε άλλες χώρες. Μέσω της μελέτης αυτής αποδείχθηκε ότι οι καταναλωτές χρησιμοποιούν το διαδίκτυο για τις αγορές τους ακόμα και για τα παραφαρμακευτικά ποιόντα, και δεν είναι διατακτικοί όσον αφορά την ηλεκτρονική αγορά και φαρμακευτικών προιόντων μέσω αυτού. Η θετική στάση η οποία υπάρχει απέναντι στις ηλεκτρονικές αγορές από το καταναλωτικό κοινό, ωθεί τις επιχειρήσεις στο να προσαρμοστούν στις εξελίξεις και να φτιάξουν μια ορθή και αξιόπιστη διαδικτυακή εικόνα προκειμένου να μπορέσουν να προωθήσουν τα προϊόντα και τις υπηρεσίες τους, και να προσελκύσουν πιθανούς αγοραστές.

description: SQL is one of the most popular tools for data analysis, and it is now used by an increasing number of users without having expertise in databases. Several studies have proposed programming-by-example approaches to help such non-experts to write correct SQL queries. While existing methods support a variety of SQL features such as aggregation and nested query, they suffer a significant increase in computational cost as the scale of example tables increases. In this paper, we propose an efficient algorithm utilizing properties known in relational algebra to synthesize SQL queries from input and output tables. Our key insight is that a projection operator in a program sketch can be lifted above other operators by applying transformation rules in relational algebra, while preserving the semantics of the program. This enables a quick inference of appropriate columns in the projection operator, which is an essential component in synthesis but causes combinatorial explosions in prior work. We also introduce a novel form of constraints and its top-down propagation mechanism for efficient sketch completion. We implemented this algorithm in our tool PATSQL and evaluated it on 226 queries from prior benchmarks and Kaggle's tutorials. As a result, PATSQL solved 68% of the benchmarks and found 89% of the solutions within a second. Our tool is available at https://naist-se.github.io/patsql/.

description: Der vorliegende Beitrag befasst sich mit Potentialen eines neuen Lehr-Lernformats für lehramtsbezogene Studiengänge in Form einer hochschulübergreifenden Ringvorlesung, die zwischen analogen und digitalen Formaten alterniert. Die inhaltliche Konzeption der Ringvorlesung bewegt sich im Themenfeld musikkulturelle Bildung – Digitalisierung – Inklusion. Erste Auswertungen von Erfahrungen lassen Momente entlang der Zusammenhänge des Onlife oder Postdigitalen erkennen. Deutlich wird aber auch, dass ein gemeinsamer konjunktiver Erfahrungsraum durch die Verflechtung von digitalen und analogen Anteilen im Jetzt und in der Zukunft im Sinne einer Bildungspraxis immer wieder neu konstituiert und ausgehandelt werden muss.

description: A reliable biomarker has not been identified to predict the outcome of traumatic brain injury (TBI) in children. Therefore, the present systematic review and meta-analysis aimed to assess the association between neuron specific enolase (NSE) and traumatic brain injury (TBI) in children. Two independent reviewers searched electronic databases of EMBASE, Cochrane library, Medline and Scopus and then they summarized the results and did a quality control check. At the end, standardized mean difference (SMD) with 95 % confidence interval (CI) and performance of NSE were assessed. 10 studies were included in the present meta-analysis. Average serum (SMD=1.3; 95 % CI: 0.5 to 2.1; p=0.001) and CSF levels (SMD=2.45; 95 % CI: 1.04 to 3.8; p<0.0001) of NSE biomarker were significantly higher in children with TBI with unfavorable outcome compared with other children. Serum NSE had an area under the curve, sensitivity and specificity of 0.75 (95 % CI: 0.72 to 0.79), 0.74 (95 % CI: 0.64 to 0.82) and 0.69 (95 % CI: 0.59 to 0.77), respectively in prediction outcome of TBI. Positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of serum NSE were 2.4 (95 % CI: 1.7 to 3.3), 0.38 (95 % CI: 0.26 to 0.55) and 6.0 (95 % CI: 3.0 to 12.0), respectively. The results show that the performance of NSE is in a moderate level in prediction of unfavorable outcome in children with TBI. However, data in this aspect is not sufficient and more studies are needed.

description: We present a new procedure using on-shell recursion to determine coefficients of integral functions appearing in one-loop scattering amplitudes of gauge theories, including QCD. With this procedure, coefficients of integrals, including bubbles and triangles, can be determined without resorting to integration. We give criteria for avoiding spurious singularities and boundary terms that would invalidate the recursion. As an example where the criteria are satisfied, we obtain all cut-constructible contributions to the one-loop n-gluon scattering amplitude, A_n^{oneloop}(...--+++...), with split-helicity from an N=1 chiral multiplet and from a complex scalar. Using the supersymmetric decomposition, these are ingredients in the construction of QCD amplitudes with the same helicities. This method requires prior knowledge of amplitudes with sufficiently large numbers of legs as input. In many cases, these are already known in compact forms from the unitarity method.

Where worlds collide : social polarisation at the community level in Vancouver's Gastown/Downtown Eastside
Creators: name: Smith, Heather
Publisher: name: University of British Columbia
Year: 2009

description: Gastown, Vancouver's birthplace, is a small historic district embedded within the broader community of the Downtown Eastside. Over the past 25 years Gastown has been slowly upgrading; refashioning itself as a loft style residential neighbourhood and central tourist destination. Over the same period the Downtown Eastside's reputation as the city's "skid road" has become firmly entrenched. The pace of this community's upgrading and downgrading has quickened over the past five years and resulted in a current geography where we find loft-style condominiums, cappuccino bars and rising affluence interspersed with needle exchanges, homeless shelters and deepening disadvantage. What we see within the Gastown/Downtown Eastside community is a convergence of the spatial processes of social polarisation and the kinds of conflicts and negotiations that result. Polarisation, most broadly defined, describes a growing socio-economic and spatial divide between the "haves" and "have-nots" of Western societies and cities. While considerable attention has been paid to polarisation's conceptual meaning and empirical definition at the national and intra-urban levels, little focus has centered on how the process can be identified and analysed at the intra-community level. In the same way that polarisation at broader scales of analysis can be viewed as the sociotemporal coincidence of pauperisation and professionalisation, this dissertation defines intracommunity polarisation as the simultaneous occurrence of socio-spatial upgrading and downgrading. Using quantitative data from the census tract level, this dissertation investigates the empirical evidence of social polarisation within Gastown/Downtown Eastside. Using qualitative data the study explores the extent to which both revitalisation and deterioration are competing for the community's future and this polarisation is being experienced and negotiated by the varied residents and stakeholders of this urban community. Ultimately this dissertation sheds light on how the characteristics and causes of community based polarisation differ and parallel those at other scales of inquiry. It also outlines the truly local factors that affect polarisation's development, entrenchment and impact and illuminates the process' inconstant character and the time lag that exists between its qualitative experience and its quantitative identification.

description: Tobacco consumption has become a major public health issue, which has motivated studies to identify and understand the biological processes involved in the smoking behavior for prevention and smoking cessation treatments. CYP2A6 has been identified as the main gene that codifies the enzyme that metabolizes nicotine. Many alleles have been identified after the discovery of CYP2A6, suggesting a wide interethnic variability and a diverse smoking behavior of the allele carrying individuals. The main purpose of this review is to update and highlight the effects of the CYP2A6 gene variability related to tobacco consumption reported from diverse human populations. The review further aims to consider CYP2A6 in future studies as a possible genetic marker for the prevention and treatment of nicotine addiction. Therefore, we analyzed several population studies and their importance at addressing and characterizing a population using specific parameters. Our efforts may contribute to a personalized system for detecting, preventing and treating populations at a higher risk of smoking to avoid diseases related to tobacco consumption.
