description: We describe the strong dual space $({\mathcal O}^s (D))^*$ for the space ${\mathcal O}^s (D) =
 H^s (D) \cap {\mathcal O} (D)$ of holomorphic functions from the Sobolev space $H^s(D)$, $s \in \mathbb Z$, over a bounded simply connected plane domain $D$ with infinitely differential boundary $\partial D$. We identify the dual space with the space of holomorhic functions on ${\mathbb C}^n\setminus \overline D$ that belong to $H^{1-s} (G\setminus \overline D)$ for any bounded domain $G$, containing the compact $\overline D$, and vanish at the infinity. As a corollary, we obtain a description of the strong dual space $({\mathcal O}_F (D))^*$ for the space ${\mathcal O}_F (D)$ of holomorphic functions of finite order of growth in $D$ (here, ${\mathcal O}_F (D)$ is endowed with the inductive limit topology with respect to the family of spaces ${\mathcal O}^s (D)$, $s \in \mathbb Z$).
 In this way we extend the classical Grothendieck-K{ö}the-Sebastião e Silva duality for the space of holomorphic functions.

description: Commentators around the world have emphasized the importance of data with statements like 'data is the oil of the next century' or 'data is the new oil' for the past decade. Has it come true? If data is so important, how important is Big Data? What is Big Data and what is the status of Big Data in Austria? This thesis is aimed to analyze the status quo of Big Data for small and medium sized enterprises in Austria. Therefore, the value chain of Big Data is used to define a basement for each single step and oppose this to actual findings that were extracted from surveys. The difference between traditional data analysis and Big Data Analytics are blurred and especially for SMEs irrelevant. It is not so much about the magnitude of data volume, velocity of processing and the variety of data (3Vs) but rather the value that can be generated out of data. New techniques like predictive analysis, machine learning and network analysis and technologies like analytical databases and parallel programming models are not yet in focus for most SMEs, although in terms of the best solution for a certain problem the enterprises will use the best model available. Use cases and success stories for Big Data in the manufacturing field like smart production lines and predicting service intervals are not sufficiently sound for SMEs to embark on the Big Data paradigm. The major challenges for Big Data initiatives are a lack of knowledge within the companies, a lack of skilled workforce, privacy concerns and data security issues. The latter problems should be addressed in a data strategy which should be developed upfront a Big Data initiative and has to be seen interconnected with the business strategy. To avoid missing business opportunities, SMEs should carefully analyze the potential impact that a deeper analysis of data could have on their customers and processes regardless of where the data will be acquired, how they will be stored or processed. For these technical issues, SMEs can easily find the right service facilitated by a Big Data platform service provider. Ventures that are not yet dependent on data like companies were on oil years ago certainly have further potential to improve productivity and service quality for their customers by starting Big Data initiatives.

description: In today's competitive marketplace, companies, especially in the au-tomotive manufacturing field are under strong pressure to introduce new products frequently to secure their long-term survival and profitability by staying ahead of their competitors. It is not possible for every company, even ones with huge resources, to cope progressively or immediately with the market requirements, due to knowledge dynamics and customer behaviour changes. This increased competition in the market place and reduced product life cycles due to market dynamics force companies to develop new products faster. This also forces companies to develop their knowledge resources quicker. In addition, for many a company, proto-typing the new product is a vital activity that can make a huge di¿erence between successful and unsuccessful entry of the said product into the market. physical prototyping is usually very expensive and time consuming , especially if modifications resulting from design reviews involve not only prototype redesign but also tool redesign. The advancement in technology and advanced computers has enabled the use of digital and virtual tech-niques for prototyping that forgo with costly prototype and production tool manufacturing. A product development platform using virtuality and virtual product development techniques is envisaged to reduce the product design lifecycle time. This platform is then integrated into the modified phase review process developed by Cooper. Focus on automotive industry is prioritised. But the process is suitable for all NPD projects.

description: We develop the $n$-dimensional cosmology for $f(\mathcal{G})$ gravity, where $\mathcal{G}$ is the \emph{Gauss-Bonnet} topological invariant. Specifically, by the so-called Noether Symmetry Approach, we select $f(\mathcal{G})\simeq \mathcal{G}^k$ power-law models where $k$ is a real number. In particular, the case $k = 1/2$ for $n=4$ results equivalent to General Relativity showing that we do not need to impose the action $R+f(\mathcal{G})$ to reproduce the Einstein theory. As a further result, de Sitter solutions are recovered in the case where $f(\mathcal{G})$ is non-minimally coupled to a scalar field. This means that issues like inflation and dark energy can be addressed in this framework. Finally, we develop the Hamiltonian formalism for the related minisuperspace and discuss the quantum cosmology for this model.
Frequency-channel interactions of the auditory steady-state responses at different levels of the auditory pathways
Creators: name: Armstron, Maxine T.
Publisher: name: University of British Columbia
Year: 2010

description: This study evaluated the effect of 3 different modulation rates and 3 different rate separations on the interactions (response amplitudes) of multiple ASSRs. Responses from 12 normal-hearing subjects were examined using three amplitude-modulation rates (14,40 and 80 Hz) and four conditions: one tone (1000 Hz), two tones (1000 and 2000 Hz, presented monotically or dichotically) and four tones (500, 1000,2000 and 4000 Hz, presented monotically). Within the multiple-tone conditions, rate separation between the amplitudemodulated tones was varied from 2 to 6 Hz. A 1000-Hz tone served as the baseline condition and interactions between tones were measured as a function of the change in response amplitude from this baseline. Results indicate separation between modulation rates had no effect on the interactions between responses. Both modulation rate and condition had significant effects on ASSR interactions. In general, interactions became greater as the number of stimuli increased from 1 to 4 tones. However, each modulation rate had a different pattern of interactions. The response amplitudes for all modulation rates were significantly decreased in the four-tone condition. The two-tone dichotic condition amplitudes were decreased from the baseline for the 40-Hz ASSRs, but not for the 14- and 80-Hz ASSR amplitudes. Furthermore, the 40-Hz and 80- Hz two-tone monotic condition response amplitudes were decreased from the baseline, but not the 14-Hz ASSR amplitudes. Results from relative efficiency calculations indicate that at high intensities (80 dB SPL), ASSRs to multiple tones are not more efficient than ASSRs to single tones for any modulation rate range. The different patterns suggest that the 14-, 40- and 80-Hz ASSRs are generated in different areas along the auditory pathways. These results may be helpful in determining the usefulness of multiple ASSRs for diagnostic testing at high intensity levels and for testing auditory functioning at different levels in the auditory pathways.

description: A kommunikáció hatékonyságát a folyamatban gyakran előforduló, klasszikus korlátok rontják. A szolgáltatások minőségét egyértelműen lehet differenciálni személyzeti vonalon - talán ez az egyedüli markáns megkülönböztetési lehetőség - mi több, a személyzet-differenciálás vonulatai (válaszkészség, udvariasság, hitelesség, hozzáértés) mind-mind a kommunikációhoz köthetők. A vendéglátásban, mint szolgáltatásban ez hatványozottan igaz: a személyzet kommunikációs készségtára perdöntő súllyal bír bármely egység külső megítélésében, a járulékos információhordozók (étlap, itallap, display, honlap) pedig erősítik, vagy éppen gyengítik ezt a képet. A tanulmányban megvizsgáljuk egy budapesti magasan pozícionált étterem kommunikációs sajátosságait, megnézzük ezek speciális megnyilvánulási formáit a vendéglátóiparban, és elemezzük a szolgáltatáshoz szervesen kapcsolódó további kommunikációs csatornákat is (étlap, itallap, display, honlap). A kérdőíves megkérdezés és a mélyinterjúk eredményeképpen rávilágítunk a szolgáltatás fejleszthető területeire a még hangsúlyosabb differenciálás érdekében, s persze megerősítjük az éttermet a jó gyakorlatként (best practice) elkönyvelhető momentumaiban. ------------------------------------------------------ The efficiency of communication is spoiled by common, classical barriers. Quality of service can easily be differentiated based on personnel (this seems to be the only outstanding possibility) and even more personnel differentiation is always based on communication skills (politeness, credibility, professionalism, readiness to answer). In the hospitality industry all this is out of question: the personnel’s communication skills will be decisive in building any unit’s image, additional information channels (menu, displays, webpage) will just reinforce or weaken this. In the present study we analyse a highly positioned Budapest based restaurant’s communication characteristics, we highlight the specific features of communication within such an environment and investigate other communication channels closely related to the service (menu, displays, webpage). Based on a questionnaire survey and two structured interviews we will define areas that still have a potential for development for even better, stronger differentiation and will of course reinforce the restaurant in areas which can be taken into account as best practices.
title: Rhetoric & Reality: The Theoretical Basis of Work-Based Learning and the Lived Experience of the Foundation Degree Student
Creators: name: Wareing, Mark Philip
Publisher: name: The Open University
Year: 2012

description: This hermeneutic phenomenological study has sought to uncover the lived experience of work-based learners and their workplace mentors. Eight workplace mentors (all registered nurses) and eleven former Foundation degree students agreed to be interviewed. The research sought to identify whether a mismatch exists between theories of work-based learning as described by educationalists and theorists; compared with how it is actually experienced by a group of work-based learners and their workplace mentors. The former students had all been healthcare assistants (HCAs) working in acute clinical settings and employed within a large NHS hospital. All had completed a two year Foundation degree in Health and Social Care (FdSc) course in preparation to become assistant practitioners (AP). The start of their studies was characterised by managing conflict, establishing an identity as a learner in their own right and making sense of the assistant practitioner role, whilst their concluding lived experience was characterised by becoming an assistant practitioner, receiving recognition from peers in addition to feeling the need to prove the validity of their AP role. Being a novice or an apprentice was not the experience of former Foundation degree student participants. Four models of work-based learning were compared against the lived experiences of participants. While all four models capture the profoundly social nature of work-based learning, none of the models captured the challenge faced by Foundation degree student participants in making the transition from being a healthcare assistant and becoming a work-based learner, to becoming an assistant practitioner. This finding was particularly significant to the lived experience of all participants in this study as the assistant practitioner role was completely new to workplace mentors, their departments and the NHS hospital Trust in which the research was undertaken.

description: The aim of the paper was to assess the possibilities of obtaining advantages of the diversification effect brought by purchase of commodities in the Polish market. Investment portfolios consisting of different assets are analyzed, including both indirect and direct ways of investing in commodities. Rates of return, correlations and standard deviations are calculated for separate portfolios on the basis of empirical data (prices of assets). Results obtained allow to state that a share of commodities in portfolio brings notable benefits. Nevertheless they are limited due to an illiquid market of commodity derivatives in Poland as well as a lack of commodity indexes. / Synopsis. Celem pracy była ocena możliwości osiągnięcia korzyści z dywersyfikacji portfela za pomocą dostępnych form inwestowania w towary w warunkach polskiego rynku. Analizowano portfele inwestycyjne o różnym składzie, wykorzystujące pośrednie i bezpośrednie formy inwestowania w towary. Na podstawie danych empirycznych (cen walorów) wyznaczano stopy zwrotu, korelacje i odchylenia standardowe dla poszczególnych portfeli. Uzyskane wyniki pozwoliły stwierdzić, że wprowadzenie do portfela towarów przynosi wymierne korzyści. Tym niemniej są one ograniczone, ponieważ w Polsce nie ma płynnego rynku towarowych instrumentów pochodnych ani indeksów towarowych.

description: We present arguments that the CKM CP-violation in the standard model may be sufficient for the generation of the baryon asymmetry, if the electroweak transition in the early universe was of the cold, tachyonic, type after electroweak-scale inflation. A model implementing this is described which complies with the CMB constraints and which is falsifiable with the LHC. Numerical simulations of the tachyonic transition with an effective CP-bias indicate that the observed baryon asymmetry can be generated this way.

Diffusiophoresis of ionic catalytic particles

description: A migration of charged particles relative to a solvent, caused by a gradient of salt concentration and termed a diffusiophoresis, is of much interest being exploited in many fields. Existing theories deal with diffusiophoresis of passive inert particles. In this paper, we extend prior models by focusing on a particle, which is both passive and catalytic, by postulating an uniform ion release over its surface. We derive an expression for a particle velocity depending on a dimensionless ion flux (Damkohler number Da) and show that a charged region is formed at distances of the order of the particle size, provided the diffusion coefficients of anions and cations are unequal. When Da becomes large enough, the contribution of this (outer) region to the particle velocity dominates. In this case the speed of catalytic passive particles augments linearly with Da and is inversely proportional to the square of electrolyte concentration. As a result, they always migrate towards a high concentration region and in dilute solutions become much faster than inert (non-catalytic) ones.

description: The aim of this master thesis is to propose a methodological framework that facilitates the development of innovative products within large enterprises. The agile innovation model is designed to increase the speed of product development while at the same time allowing for enough flexibility to adapt products according to feedback from the market. Agile innovation does not only deal with the product development itself but also provides a comprehensive framework that encompasses the facilitating factors which are necessary to create an environment that is conducive to innovation. However, large firms struggle with transforming their product development efforts towards an agile innovation model due to hierarchical structures and processes that focus on stability and predictability. Therefore, this thesis develops an approach that describes the transition of large organizations from traditional product development towards the agile innovation model. It draws on findings from the field of change management to describe the necessary steps and develops a set of recommendations for organizations that attempt this transformation. The research questions focus on the agile innovation model itself and the description of the transformation process. Both are developed based on a review of extant literature and are empirically validated by conducting a qualitative case study in an Austrian telecommunications company. Based on the findings of a series of in-depth interviews, the agile innovation model is amended. The empirical findings confirm the validity of the agile innovation model and support the need for a structured approach to transformation. This thesis contributes to the discourse on agile product development by providing a better understanding of its holistic nature, the interplay of existing agile methods from various fields and the importance of enabling factors within an enterprise. It proposes a pragmatic yet systematic approach to innovation and transformation that can be applied in an enterprise context.

description: Loss function plays a vital role in supervised learning frameworks. The selection of the appropriate loss function holds the potential to have a substantial impact on the proficiency attained by the acquired model. The training of supervised learning algorithms inherently adheres to predetermined loss functions during the optimization process. In this paper, we present a novel contribution to the realm of supervised machine learning: an asymmetric loss function named wave loss. It exhibits robustness against outliers, insensitivity to noise, boundedness, and a crucial smoothness property. Theoretically, we establish that the proposed wave loss function manifests the essential characteristic of being classification-calibrated. Leveraging this breakthrough, we incorporate the proposed wave loss function into the least squares setting of support vector machines (SVM) and twin support vector machines (TSVM), resulting in two robust and smooth models termed Wave-SVM and Wave-TSVM, respectively. To address the optimization problem inherent in Wave-SVM, we utilize the adaptive moment estimation (Adam) algorithm. It is noteworthy that this paper marks the first instance of the Adam algorithm application to solve an SVM model. Further, we devise an iterative algorithm to solve the optimization problems of Wave-TSVM. To empirically showcase the effectiveness of the proposed Wave-SVM and Wave-TSVM, we evaluate them on benchmark UCI and KEEL datasets (with and without feature noise) from diverse domains. Moreover, to exemplify the applicability of Wave-SVM in the biomedical domain, we evaluate it on the Alzheimer Disease Neuroimaging Initiative (ADNI) dataset. The experimental outcomes unequivocally reveal the prowess of Wave-SVM and Wave-TSVM in achieving superior prediction accuracy against the baseline models.
Tunable quantum spin chain with three-body interactions

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We introduce a generalization of the Fredkin spin chain with tunable three-body interactions expressed in terms of conventional spin-half operators. Of the model's two free parameters, one controls the preference for Ising antiferromagnetism and the other controls the strength of quantum fluctuations. In this formulation, the so-called $t$-deformed model (an exactly solvable, frustration-free Hamiltonian) lives on a unit circle centered on the origin of the phase diagram. The circle demarcates the boundary between ferromagnetic order inside and various antiferromagnetic phases outside. Throughout most of the non-ferromagnetic parts of the phase diagram, the ground state has Dyck word form: i.e., all contributing spin configurations exhibit perfect matching and nesting of spin up and spin down. The exceptions are two regions in which Dyck word mismatches are energetically favorable. We remark that in those regions the energy level spacing can be exponentially small in the system size. It is also the case that exact diagonalization reveals a highly idiosyncratic energy spectrum, presumably because the hard spin twist at the chain ends induces strong incommensurability effects on the bulk system when the chain length is small. As a convergence check, we benchmark our DMRG results to near-double-precision floating-point accuracy against analytical results at exactly solvable points and against exact diagonalization results for small system sizes across the entire parameter space.

description: We study the exclusive electroproduction of a photon pair in the kinematical regime where the diphoton invariant mass is large and where the nucleon flies almost in its original direction. We discuss the relative importance of the QCD process where the two photons originate from a quark line compared to the single (double) Bethe-Heitler processes where one (two) photons originate from the lepton line. This process turns out to be a promising tool to study generalized parton distributions in the nucleon, both at the medium energy of JLab and at a high energy electron ion collider.

description: Surrogate models provide a quick-to-evaluate approximation to complex computational models and are essential for multi-query problems like design optimisation. The inputs of current deterministic computational models are usually high-dimensional and uncertain. We consider Bayesian inference for constructing statistical surrogates with input uncertainties and intrinsic dimensionality reduction. The surrogate is trained by fitting to data obtained from a deterministic computational model. The assumed prior probability density of the surrogate is a Gaussian process. We determine the respective posterior probability density and parameters of the posited statistical model using variational Bayes. The non-Gaussian posterior is approximated by a Gaussian trial density with free variational parameters and the discrepancy between them is measured using the Kullback-Leibler (KL) divergence. We employ the stochastic gradient method to compute the variational parameters and other statistical model parameters by minimising the KL divergence. We demonstrate the accuracy and versatility of the proposed reduced dimension variational Gaussian process (RDVGP) surrogate on illustrative and robust structural optimisation problems where cost functions depend on a weighted sum of the mean and standard deviation of model outputs.

description: This work provides a ground for a quantitative interpretation of experiments on step bunching during sublimation of crystals with a pronounced Ehrlich-Schwoebel (ES) barrier in the regime of weak desorption. A strong step bunching instability takes place when the kinetic length is larger than the average distance between the steps on the vicinal surface. In the opposite limit the instability is weak and step bunching can occur only when the magnitude of step-step repulsion is small. The central result are power law relations of the between the width, the height, and the minimum interstep distance of a bunch. These relations are obtained from a continuum evolution equation for the surface profile, which is derived from the discrete step dynamical equations for. The analysis of the continuum equation reveals the existence of two types of stationary bunch profiles with different scaling properties. Through a mathematical equivalence on the level of the discrete step equations as well as on the continuum level, our results carry over to the problems of step bunching induced by growth with a strong inverse ES effect, and by electromigration in the attachment/detachment limited regime. Thus our work provides support for the existence of universality classes of step bunching instabilities [A. Pimpinelli et al., Phys. Rev. Lett. 88, 206103 (2002)], but some aspects of the universality scenario need to be revised.

description: The article shows the changes in the labour force in agriculture in the years 1996-2007, against the background of changes in demography and economy (farm size), as a result of socio- economic changes and Poland’s membership in the European Union. The fact that Poland joined the European Union has positively influenced the economic activity in agriculture and, at the same time, it has slowed down the process of transferring agricultural labour force to non-farming jobs. In 2007 a positive change in the demographic structure of farming population was recorded. Generally, between 1996 and 2007 a decline in labour force was noted, but between 2002 and 2007 a slight increase was recorded. A negative phenomenon, however, is the fact that a large portion of the labour force in individual farms remains unused. Over-intensive employment in farming may lead to both open and hidden agricultural unemployment. Structural and quantitative changes in labour force show diverse intensity in individual voivodeships. Northern Poland, where large-size farms predominate, has lower density of farming population and a larger percentage of hired labour force. Central and South-Eastern Poland, however, shows a high density of population working in farming and a high share of people in working age running family farms. / Synopsis. W artykule przedstawiono zmiany zachodzące w zasobach siły roboczej w rolnictwie w latach 1996-2007 pod wpływem przemian społeczno-gospodarczych oraz członkostwa Polski w Unii Europejskiej. Szczegółowej analizie poddano zmiany liczby pracujących w gospodarstwach rolnych w jednostkach AWU na tle zmian demograficznych i ekonomicznych (wielkości gospodarstw rolnych) oraz zmiany w strukturze płci i wieku użytkowników gospodarstwa rolnego.
title: The role of the end user in the value creation process
Creators: name: Holcomb, Michael Scott

Subjects: subject: Value Creation
subject: User Involvement
subject: Collaboration
subject: Business Model

description: The topic of my Master's Thesis is 'The Role of the End User in the Value Creation Process'. The problem that I am seeking to resolve is how to create, capture, and sustain value to both the business and the customer through collaboration. In order to resolve this problem the question that I have attempted to answer is 'How can user involvement become a sustainable business model in the digital marketplace?' The proposed business model that I will develop and test will be within the context of digital publishing. The focus will be on the collaboration between the end user community and the publisher to create and sustain value. As I have progressed through seeking the answer to the question in this study I have focused on five goals. First, defining what user involvement looks like. Second, analyzing a business model built upon user involvement. Third, determining the role of the stakeholders in the business model. Forth, identifying what enables or hinders user involvement as a sustainable business model. Fifth, assessing the value created for the stakeholders and how that value can be sustained. These goals provided me with a structure and framework around which I was able to progress in my research and analysis. Research clearly demonstrates that there are common techniques and strategies that can increase a business-s effectiveness via collaboration with customers. What we know is that building an engaged relationship with customers is vital. In my thesis I seek to provide a model for how to build and sustain that relationship through engagement and collaboration.
О понятии народа в текстах Ю. Ф. Самарина

description: Юрий Федорович Самарин — одна из ключевых фигур в истории славянофильской политической мысли. В свою очередь, для славянофильства одним из ключевых понятий является понятие народа. В данной статье анализируется смысловое наполнение понятия народа в текстах Самарина 1840–1860-х — в переписке, черновых заметках и опубликованных при жизни статьях. Понятие «народ» оказывается весьма противоречивым вследствие целого ряда обстоятельств. Во-первых — общеромантического переплетения «субстанциального» и эмпирического понимания народа. Во-вторых — попытки соединить понимание народа в русле политической теории, как носителя суверенитета, и «народ» в значении «простого народа», наряду с «другими сословиями», тем самым оказывающимися исключаемыми из «политического тела». Более того, противоречия теоретического плана обнаруживаются и на уровне политической трактовки дихотомии «народ»/«общество», где последнее понимается как «народ» взятый в аспекте «самосознания», при этом «общество», как состоящее из «личностей», является вместе с «народом» носителем «народности», но не является «народом» и, следовательно, в рамках проблемы «народного суверенитета» понятийно оказывается проблематизировано в возможности образовывать «народное тело», выступая скорее его репрезентантом и порождая двойственность репрезентантов, в лице «царя» и «общества». Вместе с тем демонстрируется, что сочетание субстанциалистской и эмпирической трактовок «народа» делает Самарина чувствительным к объективирующему, просвещенческому дискурсу — и дает ресурс для трактовки эмпирического «народа» в категориях субъектности.

description: Product innovations are a powerful instrument for gaining a competitive advantage that determine the growth of company’s market share. Howeever the majority of Polish food industry companies show a low activity in this area, which can result in losing their competitiveness in local and global markets. In the nearest future the companies should be more focused on the Research & Development (R&D) activities as well as on new products’ distribution and sales methods. Strengthening product innovation activities of Polish food industry companies will help introducing new products that meet modern consumer expectations. / Synopsis. Innowacje produktowe są ważnym narzędziem uzyskiwania przewagi rynkowej, determinującym rozwój przedsiębiorstw w długim okresie. Mimo tego, aktywność polskich przedsiębiorstw spożywczych w tym obszarze jest ciągle niska. Utrzymywanie się tej postawy może się przyczyniać do osłabienia konkurencyjności rodzimych przedsiębiorstw na rynku krajowym oraz globalnym. Najbliższe lata powinny być zatem poświęcone na działalność badawczo-rozwojową (B+R) oraz rozwijanie nowoczesnych metod wparcia dystrybucji i sprzedaży. Zwiększenie aktywności polskich przedsiębiorstw przemysłu spożywczego w obszarze innowacyjnej działalności produktowej będzie sprzyjać także wprowadzaniu produktów dopasowanych do potrzeb współczesnych konsumentów.

description: Word embeddings or distributed representations of words are being used in various applications like machine translation, sentiment analysis, topic identification etc. Quality of word embeddings and performance of their applications depends on several factors like training method, corpus size and relevance etc. In this study we compare performance of a dozen of pretrained word embedding models on lyrics sentiment analysis and movie review polarity tasks. According to our results, Twitter Tweets is the best on lyrics sentiment analysis, whereas Google News and Common Crawl are the top performers on movie polarity analysis. Glove trained models slightly outrun those trained with Skipgram. Also, factors like topic relevance and size of corpus significantly impact the quality of the models. When medium or large-sized text sets are available, obtaining word embeddings from same training dataset is usually the best choice.
