description: Energy disaggregation is the process of estimating the energy consumed by individual electrical appliances given only a time series of the whole-home power demand. Energy disaggregation researchers require datasets of the power demand from individual appliances and the whole-home power demand. Multiple such datasets have been released over the last few years but provide metadata in a disparate array of formats including CSV files and plain-text README files. At best, the lack of a standard metadata schema makes it unnecessarily time-consuming to write software to process multiple datasets and, at worse, the lack of a standard means that crucial information is simply absent from some datasets. We propose a metadata schema for representing appliances, meters, buildings, datasets, prior knowledge about appliances and appliance models. The schema is relational and provides a simple but powerful inheritance mechanism.

Evidence of a short-range incommensurate $d$-wave charge order from a fermionic two-loop renormalization group calculation of a 2D model with hot spots

description: The two-loop renormalization group (RG) calculation is considerably extended here for the two-dimensional (2D) fermionic effective field theory model, which includes only the so-called "hot spots" that are connected by the spin-density-wave (SDW) ordering wavevector on a Fermi surface generated by the 2D $t-t'$ Hubbard model at low hole doping. We compute the Callan-Symanzik RG equation up to two loops describing the flow of the single-particle Green's function, the corresponding spectral function, the Fermi velocity, and some of the most important order-parameter susceptibilities in the model at lower energies. As a result, we establish that -- in addition to clearly dominant SDW correlations -- an approximate (pseudospin) symmetry relating a short-range \emph{incommensurate} $d$-wave charge order to the $d$-wave superconducting order indeed emerges at lower energy scales, which is in agreement with recent works available in the literature addressing the 2D spin-fermion model. We derive implications of this possible electronic phase in the ongoing attempt to describe the phenomenology of the pseudogap regime in underdoped cuprates.

Tight asymptotic key rate for the BB84 protocol with local randomisation and device imprecisions
Creators: name: Woodhead, Erik
Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Local randomisation is a preprocessing procedure in which one of the legitimate parties of a quantum key distribution (QKD) scheme adds noise to their version of the key and was found by Kraus et al. [Phys. Rev. Lett. 95, 080501 (2005)] to improve the security of certain QKD protocols. In this article, the improvement yielded by local randomisation is derived for an imperfect implementation of the BB84 QKD protocol, in which the source emits four given but arbitrary pure states and the detector performs arbitrarily-aligned measurements. Specifically, this is achieved by modifying an approach to analysing the security of imperfect variants of the BB84 protocol against collective attacks, introduced in [Phys. Rev. A 88, 012331 (2013)], to include the additional preprocessing step. The previously known improvement to the threshold channel noise, from 11\% to 12.41\%, is recovered in the special case of an ideal BB84 implementation and becomes more pronounced in the case of a nonideal source. Finally, the bound derived for the asymptotic key rate, both with and without local randomisation, is shown to be tight with the particular source characterisation used. This is demonstrated by the explicit construction of a family of source states and optimal attacks for which the key-rate bound is attained with equality.
Lepton pair emission in the top quark decay $t \to bW^+\ell^-\ell^+$

description: The heaviness of the top quark makes its 2-body decay mode $t \to bW^+$ to be dominant, at such level that hardly any other decay mode reaches a detectable branching ratio (BR) within the SM. Here we study the decay $t \to bW^+\ell^-\ell^+$ ($\ell=e, μ, τ$), which diverges for massless leptons, and it can reach a BR $\sim \mathcal{O}(10^{-5}\sim 10^{-6})$ for reasonable values of the low energy cut in the lepton-pair invariant mass. This rate surpasses almost any other rare decays such as $t \to cX$ ($X=γ,Z,g,H, W^+W^-$), and thus offers the possibility of being detectable. Furthermore, the estimate of this channel is relevant because it can mimic the signal arising from the lepton number violating decay $t\to bW^-\ell^+\ell^+$, when the $W$ boson decays into lepton channels.

Exponential Fermi acceleration in general time-dependent billiards

description: It is shown, that under very general conditions, a generic time-dependent billiard, for which a phase-space of corresponding static (frozen) billiards is of the mixed type, exhibits the exponential Fermi acceleration in the adiabatic limit. The velocity dynamics in the adiabatic regime is represented as an integral over a path through the abstract space of invariant components of corresponding static billiards, where the paths are generated probabilistically in terms of transition-probability matrices. We study the statistical properties of possible paths and deduce the conditions for the exponential Fermi acceleration. The exponential Fermi acceleration and theoretical concepts presented in the paper are demonstrated numerically in four different time-dependent billiards.

The Conformal Method and the Conformal Thin-Sandwich Method Are the Same

description: The conformal method developed in the 1970s and the more recent Lagrangian and Hamiltonian conformal thin-sandwich methods are techniques for finding solutions of the Einstein constraint equations. We show that they are manifestations of a single conformal method: there is a straightforward way to convert back and forth between the parameters for these methods so that the corresponding solutions of the Einstein constraint equations agree. The unifying idea is the need to clearly distinguish tangent and cotangent vectors to the space of conformal classes on a manifold, and we introduce a vocabulary for working with these objects without reference to a particular representative background metric. As a consequence of these conceptual advantages, we demonstrate how to strengthen previous near-CMC existence and non-existence theorems for the original conformal method to include metrics with scalar curvatures that change sign.

description: Eutectic Sr$_2$RuO$_4$-Ru samples with $μ$m-sized Ru-metal inclusions support inhomogeneous superconductivity above the bulk transition of Sr$_2$RuO$_4$ in the so-called 3-Kelvin phase. In Pb/Ru/Sr$_2$RuO$_4$ Josephson junctions as realized by Maeno et al., a Pb film is indirectly coupled to the superconductor Sr$_2$RuO$_4$ mediated by the proximity-induced superconducting Ru-inclusions, yielding an extended Josephson contact through the interface between Ru and Sr$_2$RuO$_4$. Motivated by this experimental setup, we formulate a sine-Gordon model for the Josephson phase of the interface, assuming a simple cylindrical shape for the Ru-inclusion hosting the proximity-induced $s$-wave superconducting phase. Considering the Sr$_2$RuO$_4$ as a chiral $p$-wave superconductor, we discuss two types of Josephson junctions, a frustrated one due to the nature of the order parameter in Sr$_2$RuO$_4$, and an unfrustrated one for the topologically trivial 3-Kelvin phase. While the latter situation displays standard junction behavior, the former yields an unusual limiting mechanism for the critical current, based on a pinning-depinning transition of a spontaneously induced magnetic flux driven by an externally applied current. We analyze different coupling limits and show that different critical currents can arise for the two topologies. This concept fits well to recent experimental data obtained for the above setup showing an anomalous temperature dependence of the critical current at the transition temperature $T_c $ of bulk Sr$_2$RuO$_4$.

description: We discuss the fate of classical type IV singularities in quantum cosmology. The framework is Wheeler-DeWitt quantization applied to homogeneous and isotropic universes with a perfect fluid described by a generalized Chaplygin gas. Such a fluid can be dynamically realized by a scalar field. We treat the cases of a standard scalar field with positive kinetic energy and of a scalar field with negative energy (phantom field). We first present the classical solutions. We then discuss in detail the Wheeler-DeWitt equation for these models. We are able to give analytic solutions for a special case and to draw conclusions for the general case. Adopting the criterion that singularities are avoided if the wave function vanishes in the region of the classical singularity, we find that type IV singularities are avoided only for particular solutions of the Wheeler-DeWitt equation. We compare this result with earlier results found for other types of singularities.

description: Co-existing frailty in older patients with hepatopancreaticobiliary (HPB) malignancies is common. This study assessed the relationship between the Rockwood Clinical Frailty scale (CFS) and systemic anti-cancer therapy dose intensity (SACT-DI) and overall survival (OS) in patients with advanced HPB malignancies. CFS was assessed prospectively for consecutive patients with newly diagnosed advanced HPB malignancy (The Christie; Sep-2019 to June-2020). Mann-Whitney U test assessed association between CFS, ECOG Performance Status (ECOG PS), and SACT-DI and Spearman’s rank assessed the association between ECOG PS, age, and frailty. Survival analysis was performed using Kaplan-Meier and Cox regression. Two hundred patients met inclusion criteria. SACT-DI was higher in Group-1 (not frail) (CFS 1–3)(median = 61%) than Group-2 (vulnerable/mildly frail) (CFS 4–5)(median = 25.1%), p < 0.001. Median OS was shorter in frail and pre-frail patients (HR 2.3(95%CI 1.8–2.9),p < 0.001. On multivariable analysis, both CFS (HR 1.5-(95%CI 1.2–1.9), p = 0.002) and ECOG PS (HR 1.9 (95%CI 1.6–2.3), p < 0.001) were independent prognostic factors for OS. Frailty assessments, in addition to ECOG PS, may identify patients that will benefit from systemic therapy and are both independent prognostic factors for OS.

description: We report the results from a 19-h integration with the SPIRE Fourier Transform Spectrometer aboard the Herschel Space Observatory which has revealed the presence of a molecular outflow from the Cosmic Eyelash (SMM J2135-0102) via the detection of blueshifted OH absorption. Detections of several fine-structure emission lines indicate low-excitation HII regions contribute strongly to the [CII] luminosity in this z = 2.3 ULIRG. The OH feature suggests a maximum wind velocity of 700 km/s, which is lower than the expected escape velocity of the host dark matter halo, ~1000 km/s. A large fraction of the available molecular gas could thus be converted into stars via a burst protracted by the resulting gas fountain, until an AGN-driven outflow can eject the remaining gas.

description: We analyze the capacity of a continuous-time, time-selective, Rayleigh block-fading channel in the high signal-to-noise ratio (SNR) regime. The fading process is assumed stationary within each block and to change independently from block to block; furthermore, its realizations are not known a priori to the transmitter and the receiver (noncoherent setting). A common approach to analyzing the capacity of this channel is to assume that the receiver performs matched filtering followed by sampling at symbol rate (symbol matched filtering). This yields a discrete-time channel in which each transmitted symbol corresponds to one output sample. Liang & Veeravalli (2004) showed that the capacity of this discrete-time channel grows logarithmically with the SNR, with a capacity pre-log equal to $1-{Q}/{N}$. Here, $N$ is the number of symbols transmitted within one fading block, and $Q$ is the rank of the covariance matrix of the discrete-time channel gains within each fading block. In this paper, we show that symbol matched filtering is not a capacity-achieving strategy for the underlying continuous-time channel. Specifically, we analyze the capacity pre-log of the discrete-time channel obtained by oversampling the continuous-time channel output, i.e., by sampling it faster than at symbol rate. We prove that by oversampling by a factor two one gets a capacity pre-log that is at least as large as $1-1/N$. Since the capacity pre-log corresponding to symbol-rate sampling is $1-Q/N$, our result implies indeed that symbol matched filtering is not capacity achieving at high SNR.

The plant extract showed antibacterial effects against both the gram-positive and gram-negative bacteria in disc-diffusion assay. Gas chromatography-mass spectrometry (GC-MS) results revealed nine types of high and low molecular weight chemical entities with varying quantities in the extract. An in silico target-fishing approach identified two compounds with multi-target-directed activities. Two metabolites, 3-Oxo-18-Nor-ent-ros-4-ene-15.alpha.,16-acetonide and 4-Dehydroxy-N-(4,5-methylenedioxy-2-nitrobenzylidene)-tyramine, inhibited two promising bacterial targets, FabH and DNA gyrase B.

description: At the low temperatures of interstellar dust grains, it is well established that surface chemistry proceeds via diffusive mechanisms of H atoms weakly bound (physisorbed) to the surface. Until recently, however, it was unknown whether atoms heavier than hydrogen could diffuse rapidly enough on interstellar grains to react with other accreted species. In addition, models still require simple reduction as well as oxidation reactions to occur on grains to explain the abundances of various molecules. In this paper we investigate O-atom diffusion and reactivity on a variety of astrophysically relevant surfaces (water ice of three different morphologies, silicate, and graphite) in the 6.5 - 25 K temperature range. Experimental values were used to derive a diffusion law that emphasizes that O atoms diffuse by quantum mechanical tunnelling at temperatures as low as 6.5 K. The rate of diffusion on each surface, based on modelling results, were calculated and an empirical law is given as a function of the surface temperature. Relative diffusion rates are k_H2Oice > k_sil > k_graph >> k_expected. The implications of an efficient O-atom diffusion over astrophysically relevant time-scales are discussed. Our findings show that O atoms can scan any available reaction partners (e.g., either another H atom, if available, or a surface radical like O or OH) at a faster rate than that of accretion. Also, as dense clouds mature H2 becomes far more abundant than H and the O/H ratio grows, the reactivity of O atoms on grains is such that O becomes one of the dominant reactive partners together with H.

Elle n’existait pas il y a 20 ans, elle est aujourd’hui devenue le support vital d’une grande partie de nos activités humaines. Internet est né en 1969 (4 nœuds au début du réseau Arpanet) et a beaucoup grandi depuis. Le nombre de sites web publics est passé de quelques milliers dans les années 90 à plus de 300 millions en 2011. La révolution de la cryptologie asymétrique (systèmes Diffie-Helmann en 1976 et RSA en 1977) a ouvert le chemin de la sécurisation de l’Internet et rendu son développement possible : pour la première fois, deux personnes qui ne se connaissent pas peuvent échanger à distance de l’information en toute confidentialité en recourant, notamment, à des certificats, ce que ne permettait pas jusqu’alors la cryptologie traditionnelle, la cryptologie symétrique. Le cyberespace continue aujourd’hui sa croissance exponentielle, tout en subissant des transforma tions de fond qui accroissent les risques de sécurité pour ses utilisateurs.

description: Inhomogeneous chiral-symmetry breaking phases at non-vanishing chemical potential and temperature are studied within a two-flavor quark-meson model in the chiral limit. The analysis is performed beyond the standard mean-field approximation by taking into account the Dirac-sea contributions of the quarks. Compared with the case where the Dirac sea is neglected, we find that the inhomogeneous phase shrinks, but in general does not disappear. It is shown within a Ginzburg-Landau analysis that the Lifshitz point of the inhomogeneous phase coincides with the tricritical point if the ratio between sigma-meson and constituent quark mass in vacuum is chosen to be $m_σ/M = 2$, corresponding to the fixed mass ratio in the Nambu--Jona-Lasinio model. In the present model, however, this ratio can be varied, offering the possibility to separate the two points. This is confirmed by our numerical calculations, which demonstrate a strong sensitivity of the size of the inhomogeneous phase on $m_σ$. Finally, we uncover a general instability of the model with respect to large wave numbers of the chiral modulations, which calls for further improvements beyond the present approximation.

description: Diagonal quantum circuits are quantum circuits comprising only diagonal gates in the computational basis. In spite of a classical feature of diagonal quantum circuits in the sense of commutativity of all gates, their computational power is highly likely to outperform classical one and they are exploited for applications in quantum informational tasks. We review computational power of diagonal quantum circuits and their applications. We focus on the computational power of instantaneous quantum polynomial-time (IQP) circuits, which are a special type of diagonal quantum circuits. We then review an approximate generation of random states as an application of diagonal quantum circuits, where random states are an ensemble of pure states uniformly distributed in a Hilbert space. We also present a thermalizing algorithm of classical Hamiltonians by using diagonal quantum circuits. These applications are feasible to be experimentally implemented by current technology due to a simple and robust structure of diagonal gates.

В статье предпринимается попытка разграничить этапы становления новой дисциплины – «нейрообразования» – и представить основные тенденции её развития на глобальном уровне, начиная от появления термина «нейрообразование» в 1981 г. В статье представлены также другие термины для обозначения дисциплины, объединяющей нейронауки и образование. История развития и сближения нейрообразования с практикой обучения доказывает, что ознакомление с новейшими данными нейронаук и результатами нейроисследований способно помочь учителям избрать и правильно использовать наиболее эффективные образовательные стратегии, учитывая индивидуальные особенности учащихся. Однако до сих пор актуальна проблема разграничения реальных данных в области нейрообразования от «нейромифов». Поэтому серьёзное внимание в развитых странах уделяется подготовке и переподготовке учителей, а также привлечению педагогов-практиков к нейроисследованиям в сфере образования. Ученым такое сотрудничество также необходимо для верификации и эмпирической проверки результатов экспериментов, полученных в лабораторных условиях.

description: Wireless sensor networks (WSNs) have enabled continuous monitoring of an area of interest (body, room, region, etc.) while eliminating expensive wired infrastructure. Typically in such applications, wireless sensor nodes report the sensed values to a sink node, where the information is required for the end-user. WSNs also provide the flexibility to the end-user for choosing several parameters for the monitoring application. For example, placement of sensors, frequency of sensing and transmission of those sensed data. Over the years, the advancement in embedded technology has led to increased processing power and memory capacity of these battery powered devices. However, batteries can only supply limited energy, thus limiting the lifetime of the network. In order to prolong the lifetime of the deployment, various efforts have been made to improve the battery technologies and also reduce the energy consumption of the sensor node at various layers in the networking stack. Of all the operations in the network stack, wireless data transmission and reception have found to consume most of the energy. Hence many proposals found in the literature target reducing them through intelligent schemes like power control, reducing retransmissions, etc. In this article we propose a new framework called Virtual Sensing Framework (VSF), which aims to sufficiently satisfy application requirements while conserving energy at the sensor nodes.

Конкурсная деятельность рассматривается как фактор, обеспечивающий более глубокое изучение студентами учебных дисциплин и формирование профессиональных навыков. Стимул для поиска новых педагогических технологий в системе СПО – повышение уровня запросов работодателей, что связано с ростом новых технологий и общим развитием экономики. Требования к молодым специалистам со стороны современных предприятий и организаций расширяются, в список запросов включаются не только высокий уровень знаний и развитые профессиональные навыки, но и коммуникативные способности, креативность, желание активно развиваться в рамках своей профессии. Для формирования таких качеств недостаточно традиционных форм обучения, требуется опора на деятельностный подход для создания целого ряда компетенций, актуальных в современных условиях. Специфика конкурсной деятельности позволяет нам говорить о возможности развития мотивации студентов для расширения практических навыков в ходе обучения. Участие в конкурсной деятельности предполагает включение в соревновательную, игровую атмосферу, а также возможность получения приза, всеобщего признания, повышения статуса в учебном коллективе. Такие условия стимулируют учащихся к более активному и осмысленному изучению учебных дисциплин и совершенствованию в профессиональной сфере. Ключевой тип конкурсов для системы СПО – конкурс профессионального мастерства. Для обеспечения эффективности профконкурсов необходимы: создание мотивирующей среды; обеспечение нормативно-правового аспекта конкурсных процедур; реализация педагогического сопровождения учащихся; расширение числа и масштаба конкурсов с привлечением к ним внимания потенциальных работодателей.

description: Using quantum mechanical perturbation theory (PT) we analyze how the energy of perturbation of different orders is renormalized in solids. We test the validity of PT analysis by considering a specific case of spin-orbit coupling as a perturbation. We further compare the relativistic energy and the magnetic anisotropy from the PT approach with direct density functional calculations in FePt, CoPt, FePd, MnAl, MnGa, FeNi, and tetragonally strained FeCo. In addition using decomposition of anisotropy into contributions from individual sites and different spin components we explain the microscopic origin of high anisotropy in FePt and CoPt magnets.

description: Determining the Jordan canonical form of the tensor product of Jordan blocks has many applications including to the representation theory of algebraic groups, and to tilting modules. Although there are several algorithms for computing this decomposition in literature, it is difficult to predict the output of these algorithms. We call a decomposition of the form $J_r\otimes J_s=J_{λ_1}\oplus\cdots\oplus J_{λ_b}$ a `Jordan partition'. We prove several deep results concerning the $p$-parts of the $λ_i$ where $p$ is the characteristic of the underlying field. Our main results include the proof of two conjectures made by McFall in 1980, and the proof that ${\rm lcm}(r,s)$ and $\gcd(λ_1,\dots,λ_b)$ have equal $p$-parts. Finally, we establish some explicit formulas for Jordan partitions when $p=2$.

description: Рассматриваются проблемы современного языкового образования в аспекте педагогической и межпредметной интеграции. Вопросы интеграции современного иноязычного образования и междисциплинарного (межпредметного) проектирования приобретают сегодня наибольшую актуальность. Актуальность интеграции современного иноязычного образования и других дисциплин, в частности, физико-математического цикла, обусловлена все возрастающими требованиями к уровню образования обучающихся и сформированности их предметных, языковых, коммуникативных, информационных и других компетенций. Межпредметная интеграция и межпредметные связи выступают выражением интеграционных процессов в современном иноязычном образовании и имеют чрезвычайно важное значение для совершенствования практической и научно-теоретической подготовки обучающихся. Они способствуют развитию познавательной активности и креативности, а также повышению учебной мотивации обучающихся и обеспечивают достаточно высокий уровень сформированности предметных, языковых, лингвистических и информационно-коммуникативных компетенций. Создание интегративных курсов в результате реализации идеи межпредметной интеграции является актуальным в связи с необходимостью решать практико-ориентированные задачи школьного образования. Целью создания и внедрения в учебный процесс интегрированных межпредметных курсов является формирование билингвально-интегративных знаний, а также развитие информационнокоммуникативных умений и навыков. Результатом междисциплинарной интеграции является формирование у обучающихся интегративных компетенций, сочетающих содержательные компоненты взаимодействующих дисциплин и процессуальные компоненты компьютерной обучающей среды.
title: Characteristics and trends of the Campbell Plateau Meander in the Southern Ocean

description: The Southern Ocean is a crucial component of the global climate system and has absorbed a large proportion of anthropogenic heat and carbon emitted since the pre-industrial era. The Antarctic Circumpolar Current is composed of fronts, jets, and meanders. Meanders are "meandering" currents, often overlapping the location of fronts and close to topographic features, and are sites of locally enhanced vertical transport and mixing. Although meanders are key sites of interactions between the surface and deeper waters, their response to climate change is largely unexplored. In this study, we investigate the Campbell Plateau meander south of New Zealand using satellite altimetry data over the 1993 - 2020 period. We apply a "local gradient maxima" method to absolute dynamical topography data from satellite altimetry to identify the meander's location. The meander's width and geostrophic current speed are also derived. The linear trends of the meander's meridional displacement, width, as well as speed are estimated and their statistical significance is tested. From 1993 to 2020, the meander's location has been largely fixed, except for downstream from the Plateau shifting northwards by 0.4° latitude per decade. The meander has become flatter at the western edge of the Plateau but steeper at its eastern edge. Furthermore, the meander has overall been widening by 2 km per decade and accelerating by 0.01 m s\(^ {-1}\)per decade, particularly downstream from the Plateau. These findings are similar to other results from ongoing work on the Agulhas-Kerguelen standing meander located in the Indian sector of the Southern Ocean. While we cannot attribute these trends to one particular forcing, we discuss several hypotheses. The observed widening and accelerating of the meander may hinder the cross-frontal transport of heat and other tracers but could enhance the local vertical tracer transport. Whether these trends are applicable to the whole Southern Ocean meanders remains to be verified.

description: Understanding the biasing between the clustering properties of halos and the underlying dark matter distribution is important for extracting cosmological information from ongoing and upcoming galaxy surveys. While on sufficiently larges scales the halo overdensity is a local function of the mass density fluctuations, on smaller scales the gravitational evolution generates non-local terms in the halo density field. We characterize the magnitude of these contributions at third-order in perturbation theory by identifying the coefficients of the non-local invariant operators, and extend our calculation to include non-local (Lagrangian) terms induced by a peak constraint. We apply our results to describe the scale-dependence of halo bias in cosmologies with massive neutrinos. The inclusion of gravity-induced non-local terms and, especially, a Lagrangian $k^2$-contribution is essential to reproduce the numerical data accurately. We use the peak-background split to derive the numerical values of the various bias coefficients from the excursion set peak mass function. For neutrino masses in the range $0\leq \sum_i m_{ν_i} \leq 0.6$ eV, we are able to fit the data with a precision of a few percents up to $k=0.3\, h {\rm \,Mpc^{-1}}$ without any free parameter.

Exploring the Challenges of Incorporating Social Media into Integrated Marketing Communications (IMC)

description: The emergence of social media has provided numerous benefits for organisations and become a vital component of their marketing strategies. However, marketers still face several challenges in incorporating social media into integrated marketing communications (IMC) programs. Thus, this thesis aims at understanding how advertising agencies integrate social media into IMC and investigates the challenges that advertising agencies in Australia and the United Arab Emirates face in integrating social media into IMC programs. The purpose of this study is to answer the following three questions: first, what are the challenges that advertising agencies face when integrating social media into IMC programs? Second, how do advertising agencies overcome the challenges of integrating social media into IMC programs? Third, what is the role of the RBV in the agency–client relationship? I adopted a mixed methods approach to develop a comprehensive understanding of the research issue. In the preliminary study, I employed semi-structured interviews with 30 advertising campaign specialists responsible for developing social media campaigns and integrating them into IMC programs. The concepts and insights gained from this qualitative study then enabled the development of a questionnaire for a quantitative study. I distributed the questionnaire to 53 advertising campaign specialists, which yielded 159 observations (53 participants × 3 campaigns). The results reveal seven challenges that influence the incorporation of social media into IMC programs: risk acceptance, budget, client expertise, trust, target audience, agency–client collaboration and brand strategy. These challenges are responsible for many conflicts between advertising agencies and clients that decrease the level of social media integration into IMC programs. Clients may have the required resources, but the major issue underlying the failure to integrate social media into an IMC program is that the resources are not used in a collaborative way. Furthermore, the clients have a greater responsibility and can substantially assist their advertising agencies to avoid or overcome these challenges because they have a significant influence on their advertising agencies. Therefore, clients need to work with their advertising agencies in a collaborative way to effectively share and utilise resources to deliver a high level of social media integration into their IMC program. The thesis concludes by providing theoretical contributions, managerial implications, research limitations and recommendations for further research.

description: Описаны возможные подходы к формированию информационной культуры школьников и педагогов в условиях реализации федеральных государственных образовательных стандартов и профессиональных стандартов для педагога. Рассмотрены понятия «информационная культура» и «информационная грамотность», определены основные умения, составляющие эти категории. В условиях возрастающих объемов информации все труднее становится ориентироваться, получать и преобразовывать нужную информацию. Пробелы в умениях по работе с информацией приводят подростка к неуспешному освоению учебных дисциплин, неосознанному выбору профессиональной подготовки. Поэтому знакомство с основами информационной грамотности должно начинаться в начальной школе, затем системно и целенаправленно продолжаться в основной, так как запоздалое формирование одних структурных компонентов информационной грамотности в силу психологических особенностей развития личности может привести к невозможности развития других. Современный человек должен уметь работать с информацией на протяжении всей жизни, поэтому информационная грамотность является не только необходимым условием успешного обучения в школе, но и особым аспектом социальной жизни, необходимым в качестве предмета, средства и результата социальной активности человека. Обосновывается поэтапность развития умений по работе с информацией обучающихся основной школы. В соответствии с нормативными документами определены основные умения, уровни овладения детьми способами работы с текстами. Автором показаны различные типы заданий для взаимодействия со школьниками, поэтапное использование которых приводит к успешному решению задач данного направления образовательного процесса. Чтобы педагоги смогли составлять задания самостоятельно, для каждого умения была сформулирована характеристика деятельности обучающегося для полного понимания его сути и для избежания ошибок при составлении заданий. В начале формирования каждого умения рекомендуется предлагать обучающимся простые задания только на проверку этого умения или даже одной-двух операций из этого умения. Информационная культура учителя является не только необходимым инструментом для его непрерывного образования, но и объектом непрерывного образования каждого педагога.
A minimal mechanism leading to discontinuous phase transitions for short-range systems with absorbing states

description: Motivated by recent findings, we discuss the existence of a direct and robust mechanism providing discontinuous absorbing transitions in short range systems with single species, with no extra symmetries or conservation laws. We consider variants of the contact process, in which at least two adjacent particles (instead of one, as commonly assumed) are required to create a new species. Many interaction rules are analyzed, including distinct cluster annihilations and a modified version of the original pair contact process (PCP). Through detailed time dependent numerical simulations we find that for our modified models, the phase transitions are of first-order, hence contrasting with their corresponding usual formulations in the literature, which are of second-order. By calculating the order-parameter distributions, the obtained bimodal shapes as well as the finite scale analysis reinforce coexisting phases, so a discontinuous transition. These findings strongly suggest that above particle creation requirements constitute a minimum and fundamental mechanism determining the phase coexistence in short-range contact processes.
