description: The Everyday Sexism Project documents everyday examples of sexism reported by volunteer contributors from all around the world. It collected 100,000 entries in 13+ languages within the first 3 years of its existence. The content of reports in various languages submitted to Everyday Sexism is a valuable source of crowdsourced information with great potential for feminist and gender studies. In this paper, we take a computational approach to analyze the content of reports. We use topic-modelling techniques to extract emerging topics and concepts from the reports, and to map the semantic relations between those topics. The resulting picture closely resembles and adds to that arrived at through qualitative analysis, showing that this form of topic modeling could be useful for sifting through datasets that had not previously been subject to any analysis. More precisely, we come up with a map of topics for two different resolutions of our topic model and discuss the connection between the identified topics. In the low resolution picture, for instance, we found Public space/Street, Online, Work related/Office, Transport, School, Media harassment, and Domestic abuse. Among these, the strongest connection is between Public space/Street harassment and Domestic abuse and sexism in personal relationships.The strength of the relationships between topics illustrates the fluid and ubiquitous nature of sexism, with no single experience being unrelated to another.

description: The Internet facilitates large-scale collaborative projects and the emergence of Web 2.0 platforms, where producers and consumers of content unify, has drastically changed the information market. On the one hand, the promise of the "wisdom of the crowd" has inspired successful projects such as Wikipedia, which has become the primary source of crowd-based information in many languages. On the other hand, the decentralized and often un-monitored environment of such projects may make them susceptible to low quality content. In this work, we focus on Urban Dictionary, a crowd-sourced online dictionary. We combine computational methods with qualitative annotation and shed light on the overall features of Urban Dictionary in terms of growth, coverage and types of content. We measure a high presence of opinion-focused entries, as opposed to the meaning-focused entries that we expect from traditional dictionaries. Furthermore, Urban Dictionary covers many informal, unfamiliar words as well as proper nouns. Urban Dictionary also contains offensive content, but highly offensive content tends to receive lower scores through the dictionary's voting system. The low threshold to include new material in Urban Dictionary enables quick recording of new words and new meanings, but the resulting heterogeneous content can pose challenges in using Urban Dictionary as a source to study language innovation.

description: In plants, the hormone abscisic acid (ABA) functions in stress tolerance including drought, seed dormancy and development. ABA receptors (PYR/PYL/RCAR proteins) and several downstream targets have been identified. However, ABA binding and transport across the extracellular matrix (ECM) and plasma membrane upstream of ABA receptors are poorly understood. Arabidopsis ECM localized arabinogalactan protein 31 (AGP31) is primarily expressed in the vasculature, a major site of ABA biosynthesis and transport. Here, I present evidences for AGP31 functions in ABA signaling during seedling development. AGP31 affected ABA responses in seedlings. Compared to wild-type, agp31-1 knockout was less sensitive to exogenous ABA inhibition of seed germination, root elongation and showed reduced ABA marker gene expression indicating AGP31 as a positive regulator of ABA responses. In the absence of added ABA, agp31-1 seedlings exhibited transient increases in known ABA regulated transcripts encoding seed storage proteins (SSPs), oleosins and transcriptional activators of the core ABA signaling pathway, ABI3 and ABI5. Endogenous ABA levels were comparable in wild-type and agp31-1 whole seedlings. The double mutants, agp31-1 abi5-1, agp31-1 abi3-1, and ABI5 RNAi in agp31-1 expressed less SSP and oleosin mRNAs compared to agp31-1. Our genetic data show that wild-type AGP31 negative regulation of SSP and oleosin expression depends on AGP31 negative regulation of ABI3 gene function and suggested dependence on AGP31 negative regulation of ABI5 gene function. We tested whether several AGP31 domains were necessary for ABA signaling function. AGP31 has an AGP motif for addition of arabinogalactan chains, a His-rich stretch, Pro-rich and C-terminal PAC domains. Expression of AGP31 transgene lacking the AGP motif in agp31-1 failed to rescue the elevated SSP mRNA phenotype compared to agp31-1. In contrast, this assay showed AGP31 missing a conserved TDKN in the PAC domain remained functional. The results indicate that the AGP motif and possibly attached sugar chains function in AGP31 regulation of SSP expression but not the conserved TDKN region. Our results suggest a model of AGP31-mediated ABA binding or transport through its protein domains including the AGP motif at the plasma membrane-ECM interface upstream of the canonical ABA signaling pathway in seedlings

description: Die Untersuchung zeigt, dass die Spürbarkeitsklausel keine Bagatell-Schwelle im Sinne des Grundsatzes „Minima non curat praetor“ ist. Sie fungiert vielmehr als wertendes Korrektiv der Unlauterkeit, wobei die Wertungen bereits im Tatbestand der Unlauterkeit zu entfalten sind. Die vorzunehmenden Wertungen sind aus dem Telos des UWG abzuleiten, der seinerseits im Lichte überwölbender Prinzipien zu sehen ist. Maßgebliche Bedeutung erlangen dabei das Wettbewerbsverständnis und der Verhältnismäßigkeitsgrundsatz. In der bisherigen Handhabung der spürbaren Interessenbeeinträchtigung fehlt es an einem erkennbaren Bewertungsmaßstab. Dieser hat sich am Schutzzweck des UWG zu orientieren. Der Schutz der Interessen der Marktteilnehmer nach § 1 UWG zielt auf den Schutz ihrer wettbewerblichen Handlungsfreiheit als funktionale Voraussetzung des Wettbewerbs¬prozesses. Ein umfassender Rechtsgüter- und Interessenschutz ist abzulehnen. Im Mittelpunkt des „unverfälschten Wettbewerbs“ steht ebenfalls die Wettbewerbsfreiheit der Marktteilnehmer. Sonstige Allgemein¬interessen sind von der Schutzrichtung nicht umfasst. Erforderlich ist damit eine strukturierte Verhältnismäßigkeitsprüfung der schutzwürdigen Interessen der Marktteilnehmer. Die Orientierung am Grundsatz der Verhältnismäßigkeit in seiner aus dem öffentlichen Recht bekannten Strukturierung ist geeignet, die Unlauterkeit im Einzelfall unter Berücksichtigung des Schutzzwecks sinnvoll zu begrenzen. Insbesondere im Rahmen der Angemessenheit sind die wettbewerbsfunktionalen Interessen der Marktteilnehmer an einem Verbot der geschäftlichen Handlung sowie die wettbewerbsfunktionalen Interessen an ihrer Fortführung gegeneinander abzuwägen. Als Folge des herausgearbeiteten Verständnisses der Spürbarkeitsklausel ist insbesondere die Generalklausel des § 3 I UWG als monistischer Tatbestand aufzufassen, d.h. die Wertungen der Spürbarkeit sind bereits bei der Konkretisierung der Unlauterkeit zu entfalten. Die Zweigliedrigkeit des Tatbestandes ist Ausdruck der Janusköpfigkeit, die die Konkretisierung dem Rechtsanwender methodisch abverlangt. Die Darlegungs- und Beweislast für etwaige Tatsachen als Grundlage der Abwägungsentscheidung ist nach allgemeinen Grundsätzen verteilt und liegt damit beim Anspruchsteller. Eine Beweislastumkehr ist nicht angezeigt. Im Rahmen der Beispiels- und Spezialtatbestände sind dem Anspruchsteller jedoch Beweiserleichterungen nach den Grundsätzen des Anscheinsbeweises zuzugestehen, da diese Tatbestände als vertyptes Erfahrungswissen zugleich eine Aussage über das regelmäßige Vorliegen einer spürbaren Interessenbeeinträchtigung beinhalten.

description: Have we become more tolerant of dating people of different social backgrounds compared to ten years ago? Has the rise of online dating exacerbated or alleviated gender inequalities in modern courtship? Are the most attractive people on these platforms necessarily the most successful? In this work, we examine the mate preferences and communication patterns of male and female users of the online dating site eHarmony over the past decade to identify how attitudes and behaviors have changed over this time period. While other studies have investigated disparities in user behavior between male and female users, this study is unique in its longitudinal approach. Specifically, we analyze how men and women differ in their preferences for certain traits in potential partners and how those preferences have changed over time. The second line of inquiry investigates to what extent physical attractiveness determines the rate of messages a user receives, and how this relationship varies between men and women. Thirdly, we explore whether online dating practices between males and females have become more equal over time or if biases and inequalities have remained constant (or increased). Fourthly, we study the behavioural traits in sending and replying to messages based on one's own experience of receiving messages and being replied to. Finally, we found that similarity between profiles is not a predictor for success except for the number of children and smoking habits. This work could have broader implications for shifting gender norms and social attitudes, reflected in online courtship rituals. Apart from the data-based research, we connect the results to existing theories that concern the role of ICTs in societal change. As searching for love online becomes increasingly common across generations and geographies, these findings may shed light on how people can build relationships through the Internet.

description: Das Lernen an Beispielen im Allgemeinen und der Rückgriff auf bereits gelöste Beispielaufgaben im Speziellen wird in der aktuellen Lernforschung als wichtige Quelle des Erkenntnisgewinns und des Wissenszuwachses angesehen (vgl. Atkinson et al., 2000). Der Transfer von einem gelösten Aufgabenbeispiel, das als Ausgangspunkt des Transfers (source) bezeichnet wird, auf ein neues Problem (target) vollzieht sich dabei häufig mittels Analogiebildung (vgl. English, 1997, S. 5). Typische Situationen in denen diese Art des Transfers von Schülern verlangt wird, sind die Vorbereitung und Bearbeitung von Klassenarbeiten. Nur allzu oft sprechen die Ergebnisse von Klassenarbeiten im Fach Mathematik jedoch eine eindeutige Sprache: Der beschriebene Transfer fällt den Schülern auch bei gewissenhafter Vorbereitung durch die Lehrkraft schwer. Eine Frage, die im Rahmen lernpsychologischer und mathematikdidaktischer Forschung geklärt werden muss, ist deshalb: Warum tun sich Schüler so schwer auf ihre mathematische Erfahrung, ihr mathematisches Vorwissen zuzugreifen? Ein Beitrag auf dem Weg zur Klärung dieser Frage ist Inhalt der hier vorgestellten Forschungsarbeit. Es soll geklärt werden, wie Schüler versuchen mittels Analogiebildung auf ihr Vorwissen zuzugreifen, an welcher Stelle ggf. Probleme auftreten, und wann der Transfer erfolgreich ist.

description: Cities are changing constantly. All urban systems face different conditions from day to day. Even when averaged regularities can be found, urban systems will be more efficient if they can adapt to changes at the same temporal scales at which these occur. Still, the functionality of urban systems must be robust to changes, either caused by adaptation or by other factors. Technology can assist humans in designing and regulating this adaptation and robustness. To achieve this, we propose a description of cities as cybernetic systems. We identify three main components: information, algorithms, and agents, which we illustrate with current and future examples. The implications of cybernetic cities are manifold, with direct impacts on mobility, sustainability, resilience, governance, and society. Still, the potential of a cybernetic perspective on cities will not depend so much on technology as on how we use it.

description: Human embryonic stem cell-derived midbrain dopaminergic neurons could be the next generation of in vitro models to study complex neuropsychiatric disorders such as schizophrenia. A hallmark feature of this disorder is a dysregulation of dopaminergic neurotransmission in the midbrain. In this thesis, a high throughput in vitro assay was developed to directly measure release of the neurotransmitter dopamine. The assay was used to study the effects that antipsychotics have on the characteristics and function of dopaminergic neurons.

description: In times marked by political turbulence and uncertainty, as well as increasing divisiveness and hyperpartisanship, Governments need to use every tool at their disposal to understand and respond to the concerns of their citizens. We study issues raised by the UK public to the Government during 2015-2017 (surrounding the UK EU-membership referendum), mining public opinion from a dataset of 10,950 petitions (representing 30.5 million signatures). We extract the main issues with a ground-up natural language processing (NLP) method, latent Dirichlet allocation (LDA). We then investigate their temporal dynamics and geographic features. We show that whilst the popularity of some issues is stable across the two years, others are highly influenced by external events, such as the referendum in June 2016. We also study the relationship between petitions' issues and where their signatories are geographically located. We show that some issues receive support from across the whole country but others are far more local. We then identify six distinct clusters of constituencies based on the issues which constituents sign. Finally, we validate our approach by comparing the petitions' issues with the top issues reported in Ipsos MORI survey data. These results show the huge power of computationally analyzing petitions to understand not only what issues citizens are concerned about but also when and from where.

description: Hawking radiation is one essential property of quantum black hole. It results in the information loss paradox, and give important clue to the unification of quantum mechanics and general relativity. In the previous works, the boundary scalar field on the horizon of black holes were used to give the microstates of BTZ black holes and Kerr black holes. They are account for the Bekenstein-Hawking entropy. In this paper, we show that the Hawking radiation can also be derived from those scalar fields. Actually the Hawking radiation are superposition of thermal radiation of right/left sector at different temperatures. We also discuss the impact on the information loss paradox.

Year: 2017

description: Roads are clearly a critical enabling condition for improving living conditions in rural areas. Maintenance of rural roads have only relatively recently received attention in development research. Production costs, employment creation, access to markets, and investment depend on sustainable quality of infrastructure, especially transport. The purpose of the study was to examine community and stakeholders' participation on maintenance of URRAP roads projects of Oromiya Roads Authority. The design that used in the research was descriptive survey. The target populations of the study were 40 respondents from Oromiya Roads Authority. The study used the census approach where all the members of the target population were included into the study sample. The study used both primary and secondary data collection methods. The primary data was collected using questionnaires and interviews. Secondary data was derived from the organization's records. The data from the completed questionnaires was studied, re-coded and entered into the computer using the Statistical Package for Social Sciences (SPSS) version 22. Descriptive statistics were employed to analyze quantitative data. The descriptive statistics included frequency counts, means and percentages. Qualitative data was analyzed qualitatively using content analysis based on analysis of meanings and implications emanating from respondents information and documented data. The results of the study showed that CSP on the success of URRAP roads construction in GTP I was high and they had participated more in cash and free labor contribution and their participation was decreasing. It was also evident that communities and stakeholders were not participated on maintenance of URRAP roads projects in GTP I and was monitored and followed up rarely. The recommendations include providing grass root capacity building and training for woredas and developing the management system of CSP, the improvement of the work integration and cooperation between ORA and other pertinent organizations and the support given to ORA by the administrative bodies in realizing the community and different stakeholders' participation on URRAP roads maintenance projects

description: Topological connections in the single-streaming voids and multistreaming filaments and walls reveal a cosmic web structure different from traditional mass density fields. A single void structure not only percolates the multistream field in all the directions, but also occupies over 99 per cent of all the single-streaming regions. Sub-grid analyses on scales smaller than simulation resolution reveal tiny pockets of voids that are isolated by membranes of the structure. For the multistreaming excursion sets, the percolating structure is significantly thinner than the filaments in over-density excursion approach. Hessian eigenvalues of the multistream field are used as local geometrical indicators of dark matter structures. Single-streaming regions have most of the zero eigenvalues. Parameter-free conditions on the eigenvalues in the multistream region may be used to delineate primitive geometries with concavities corresponding to filaments, walls and haloes.

description: The British party system is known for its discipline and cohesion, but it remains wedged on one issue: European integration. We offer a methodology using social network analysis that considers the individual interactions of MPs in the voting process. Using public Parliamentary records, we scraped votes of individual MPs in the 57th parliament (June 2017 to April 2019), computed pairwise similarity scores and calculated rebellion metrics based on eigenvector centralities. Comparing the networks of Brexit- and non-Brexit divisions, our methodology was able to detect a significant difference in eurosceptic behaviour for the former, and using a rebellion metric we predicted how MPs would vote in a forthcoming Brexit deal with over 90% accuracy.

description: There is currently a significant need for robust and efficient methods for characterizing quantum devices. While there has been significant progress in this direction, there remains a crucial need to precisely determine the strength and type of errors on individual gate operations, in order to assess and improve control as well as reliably bound the total error in a quantum circuit given some partial information about the errors on the components. In this work, we first provide an optimal bound on the total fidelity of a circuit in terms of component fidelities, which can be efficiently experimentally estimated via randomized benchmarking. We then derive a tighter bound that applies under additional information about the coherence of the error, namely, the unitarity, which can also be efficiently estimated via a related experimental protocol. This improved bound smoothly interpolates between the worst-case quadratic and best-case linear scalings for composite error channels. As an application we show how our analysis substantially improves the achievable precision on estimates of the error rates of individual gates under interleaved randomized benchmarking, enabling greater precision for current experimental methods to assess and tune-up control over quantum gate operations.

description: Herbert Simon's classic rich-get-richer model is one of the simplest empirically supported mechanisms capable of generating heavy-tail size distributions for complex systems. Simon argued analytically that a population of flavored elements growing by either adding a novel element or randomly replicating an existing one would afford a distribution of group sizes with a power-law tail. Here, we show that, in fact, Simon's model does not produce a simple power law size distribution as the initial element has a dominant first-mover advantage, and will be overrepresented by a factor proportional to the inverse of the innovation probability. The first group's size discrepancy cannot be explained away as a transient of the model, and may therefore be many orders of magnitude greater than expected. We demonstrate how Simon's analysis was correct but incomplete, and expand our alternate analysis to quantify the variability of long term rankings for all groups. We find that the expected time for a first replication is infinite, and show how an incipient group must break the mechanism to improve their odds of success. We present an example of citation counts for a specific field that demonstrates a first-mover advantage consistent with our revised view of the rich-get-richer mechanism. Our findings call for a reexamination of preceding work invoking Simon's model and provide an expanded understanding going forward.

description: Convolutional neural network (CNN), with ability of feature learning and nonlinear mapping, has demonstrated its effectiveness in prognostics and health management (PHM). However, explanation on the physical meaning of a CNN architecture has rarely been studied. In this paper, a novel wavelet driven deep neural network termed as WaveletKernelNet (WKN) is presented, where a continuous wavelet convolutional (CWConv) layer is designed to replace the first convolutional layer of the standard CNN. This enables the first CWConv layer to discover more meaningful filters. Furthermore, only the scale parameter and translation parameter are directly learned from raw data at this CWConv layer. This provides a very effective way to obtain a customized filter bank, specifically tuned for extracting defect-related impact component embedded in the vibration signal. In addition, three experimental verification using data from laboratory environment are carried out to verify effectiveness of the proposed method for mechanical fault diagnosis. The results show the importance of the designed CWConv layer and the output of CWConv layer is interpretable. Besides, it is found that WKN has fewer parameters, higher fault classification accuracy and faster convergence speed than standard CNN.

description: E banking is a modern and recent service delivery channels in the Ethiopian banking industry and it is counted nearly a decade and half years after the first adoption of E banking technologies in Ethiopia banking industries after introducing the first Automated Teller Machine by the Commercial Bank of Ethiopia .The objective of this project work is to address the current status and progress of E banking technologies in CBE in terms of total active user of the technology , progress in transaction number performed via the technology and also address the prospect of E banking technology in CBE , the challenges and opportunities to expand the technology. To meet this objective a proportional stratified sampling design was used. Data was collected both from secondary and primary data source. The primary data source was collected, from the employees of CBE who are close to the case in their assignment of work and worked only in the four Addis Ababa districts of the bank and Addis Ababa city administration zone, via questionnaires that were both objective and open ended in nature. The secondary data was obtained from the bank's Management Information System department. The secondary data was mainly used to assess and see the status of E banking products across the aggressive expansion of the technology whereas the primary data was used to address the prospect of E banking technologies and challenges and opportunities in expanding the technology from the bank's perspective .The study used descriptive statistics and findings were described by using appropriate graphs, tables. And the findings of the study showed that the number of active, in status, user of the technology, number of transaction performed via the technology, number of newly recruited E banking customer from the newly opened account showed increment for the past five years yearly. However the percentage of increment in the number of transaction performed via the E banking technology were not proportional meaning the yearly transaction made via the technology is by far small in number this indicates even though the bank is aiming in creating cash less society still customers are cash holding one this might be due to lack of awareness how to use the technology . The primary data analysis of this project work high light that even though the E banking system of the bank presents conveniently for use there were many discouraging factors in using the technology consistently for instance network and power interruption and poor treatment of customer request and compliant handling

description: In recent years excessive monetization of football and professionalism among the players has been argued to have affected the quality of the match in different ways. On the one hand, playing football has become a high-income profession and the players are highly motivated; on the other hand, stronger teams have higher incomes and therefore afford better players leading to an even stronger appearance in tournaments that can make the game more imbalanced and hence predictable. To quantify and document this observation, in this work we take a minimalist network science approach to measure the predictability of football over 26 years in major European leagues. We show that over time, the games in major leagues have indeed become more predictable. We provide further support for this observation by showing that inequality between teams has increased and the home-field advantage has been vanishing ubiquitously. We do not include any direct analysis on the effects of monetization on football's predictability or therefore, lack of excitement, however, we propose several hypotheses which could be tested in future analyses.

description: Despite the overwhelming success of deep learning in various speech processing tasks, the problem of separating simultaneous speakers in a mixture remains challenging. Two major difficulties in such systems are the arbitrary source permutation and unknown number of sources in the mixture. We propose a novel deep learning framework for single channel speech separation by creating attractor points in high dimensional embedding space of the acoustic signals which pull together the time-frequency bins corresponding to each source. Attractor points in this study are created by finding the centroids of the sources in the embedding space, which are subsequently used to determine the similarity of each bin in the mixture to each source. The network is then trained to minimize the reconstruction error of each source by optimizing the embeddings. The proposed model is different from prior works in that it implements an end-to-end training, and it does not depend on the number of sources in the mixture. Two strategies are explored in the test time, K-means and fixed attractor points, where the latter requires no post-processing and can be implemented in real-time. We evaluated our system on Wall Street Journal dataset and show 5.49\% improvement over the previous state-of-the-art methods.

description: Hydrophobic particles inherently resist being suspended. Hydrophobic particles might be regarded as tiny solid particles surrounded by a thin gaseous shell. It has been hypothesised that hydrophobic particles act as cavitation nuclei. This cavitation behaviour would explain the translation speeds observed when hydrophobic polystyrene microspheres were driven through a liquid medium by means of ultrasound. These translation speeds corresponded to those observed with gas microbubbles of similar sizes. If hydrophobic particles do have a thin gaseous layer surrounding the solid cores, a sound field of sufficient pressure amplitude might force the gas layer to form and inertial cavity and subsequently fragment during the collapse phase. In this study, we investigated whether hydrophobic particles can be forced to suspend by using ultrasound. Hydrophobic particles of the materials C65 and ZnO can be forced to be suspended in water using ultrasound. The high-speed observations confirm that hydrophobic particles can act as cavitation nuclei. The lack of cavitation after the first pulse indicates that the gas layer surrounding the hydrophobic particle dissolves after inertial cavitation.

description: An antibubble is a gas bubble with a liquid droplet inside. Antibubbles have a potential role in ultrasonic imaging, ultrasound-guided drug delivery, and hydrocarbon leakage detection. The liquid core droplets inside antibubbles can be stabilised with a process called Pickering stability. Other systems proposed include spoke crystals to suspend the droplet or endoskeletal structures. In this study, the oscillatory response of microscopic endoskeletal antibubbles to ultrasound has been investigated, primarily to determine whether the presence of an endoskeleton attenuates the oscillation amplitude of the antibubble. Three emulsions containing (anti)bubbles were prepared for evaluation. Each emulsion was pipetted into the observation chamber of a high-speed microscopic observation system. A high-speed camera, operating at 10 million frames per second, was couples to the microscope. During camera recording, the materials were subjected to ultrasound pulses from a laboratory-assembled single-element transducer. The presence of an endoskeleton with droplets hampers the oscillation of antibubbles as compared to identical bubbles without endoskeleton and droplet content.

description: El presente trabajo analiza la representación que de la crisis económica mundial de 1929 hizo la prensa cartagenera. A su vez está encaminado a ver la percepción que tuvo este órgano, con respecto a la problemática que representó dicha coyuntura para el país, específicamente lo concerniente a índicesfiscales y laborales. Además, intenta reflexionar en qué términos leesplanteada y transmitida la información a la población. Si bien la prensa cartagenera no cataloga la depresión como algo alarmante, reconoce que ésta trajo consigo gran cantidad de dificultadespara la economía nacional. Dichos problemas se vieron acentuados en varios renglones primordiales para el desarrollo económico del país, capital y trabajo entre otros. “Para estos la depresión fue de gran impacto pues generó grandes cambios referentes a cómo obtener capital y generar trabajo para la población, influyendo esto de una manera considerable en el vuelco económico del país de la recién aplicada economía urbana a una rural encaminada al desarrollo económico del país desde la agricultura”
