description: In Germany, around 200 billion euros are invested every year in knowledge-based capital, which encompasses assets such as research and development, software and databases, organizational capital, marketing and advertising, and technical design. Yet investments in traditional capital (such as machinery and non-residential buildings) still significantly outweigh knowledge investments, standing at over 320 billion euros across the whole economy. Nevertheless, at the sector level, manufacturing, information and communication services, professional services, and financial services stand out: Investments there are dominated by knowledge-based capital. More importantly, in the years since the financial crisis, there has been no increase in the investment intensity in knowledge-based assets. DIW Berlin compiled a novel dataset on company investments in knowledge-based capital covering almost 2 million records to explore the relationship between investments and company productivity. Initial results show that knowledge-based capital has a positive effect on productivity of comparable magnitude for all the different assets measured. Furthermore, intangible assets complement material assets—therefore, investments in traditional capital goods should always be accompanied by investments in intangible assets. An economic policy to increase investment needs to take these interdependencies into account and emphasize the importance of strengthening intangible assets.

description: Over the past year, the proportion of women serving on the executive and supervisory boards of the top 100 largest banks in Germany rose slightly to almost nine and 23 percent, respectively. However, growth has come to a halt in the 60 largest insurance companies: on both executive and supervisory boards, the proportion of women has sunk to almost nine and 22 percent, respectively. For over ten years, DIW Berlin has been investigating to what extent women are represented in the top decision-making bodies of banks and insurance companies. A phase of stagnation from 2006 to 2010 was followed by a period of dynamic growth until 2014/2015 before largely returning to a slower phase of development. It seems unlikely that the average development over the past 11 years will continue linearly because most banks or insurance companies do not continue to increase the proportion of women on supervisory boards after reaching the 30 percent target mark. The development could be strengthened by a change in corporate culture. These changes include ambitious goals for more women in top positions and their timely implementation as well as a more modern corporate organization. This way, new role models can be formed and gender stereotypes can be dismantled.

description: The gender quota for supervisory boards in Germany is effective: by the end of 2017, the proportion of women on the supervisory boards of a good 100 companies that are subject to the quota had risen to 30 percent—three percentage points more than in the previous year. Almost two-thirds of the companies now have supervisory boards with at least 30 percent female members. A European comparison also shows that quota laws work—particularly under the threat of sanctions. So far, there has not been a gender quota introduced for executive boards in Germany. The development of the proportion of women on these boards has almost come to a standstill: of the 200 companies that had generated the most revenue, the proportion of women on each one’s executive board at the end of 2017 was around eight percent. In order to bring more women to executive boards and keep them there, it is in their interest for companies to quickly build up and expand their pool of potential female candidates. The next federal government should support this process of reformation by improving general conditions, including strengthening the so far voluntary guidelines for women in high leadership positions.

subject: economic outlook

description: New residential construction, in particular apartment complexes, has driven the growth in Germany’s construction industry in recent years. In 2018 and 2019 the volume of new construction will continue to expand. However, its rate of expansion will decrease and the boom of recent years will come to an end. After years of strong growth, having even occasionally surpassed the ten-percent mark, the German Institute for Economic Research expects to see a definite slowdown in the growth rates for new residential construction. Taking into account the sharply rising construction prices the real growth rates drop on to approximately one percent. The additional momentum in new non-residential construction is not likely to compensate for the end of the boom in new residential construction. Therefore the focus will shift to renovation and modernization of the existing building stock. By 2019 at the latest, these should have a higher growth rate than that of new housing. In nominal terms, the German Institute for Economic Research anticipates growth in renovation activity of around 7.5 percent for the existing housing stock and 3.5 percent growth in the non-residential sector. The greater momentum of activity around the building stock, including energy efficiency upgrades, will also help meet Germany’s climate targets. In view of the nation’s tight urban housing market, policy makers would do well to counteract the foreseeable end of the boom in new housing construction by establishing incentives for urban development and redensification as well as supporting the construction of additional residential space in urban development zones.

description: Using the QCD sum rules we test if the charmonium-like structure Y(4260), observed in the $J/ψππ$ invariant mass spectrum, can be described with a $J/ψf_0(980)$ molecular current with $J^{PC}=1^{--}$. We consider the contributions of condensates up to dimension six and we work at leading order in $α_s$. We keep terms which are linear in the strange quark mass $m_s$. The mass obtained for such state is $m_{Y}=(4.67\pm 0.09)$ GeV, when the vector and scalar mesons are in color singlet configurations. We conclude that the proposed current can better describe the Y(4660) state that could be interpreted as a $Ψ(2S) f_0(980)$ molecular state. We also use different $J^{PC}=1^{--}$ currents to study the recently observed $Y_b(10890)$ state. Our findings indicate that the $Y_b(10890)$ can be well described by a scalar-vector tetraquark current.

description: The Radon transform Rf of functions f on SO(3) has recently been applied extensively in texture analysis, i.e. the analysis of preferred crystallographic orientation. In practice one has to determine the orientation probability density function f \in L2(SO(3)) from Rf \in L2(S2\times S2) which is known only on a discrete set of points. Since one has only partial information about Rf the inversion of the Radon transform becomes an ill-posed inverse problem. Motivated by this problem we define a new notion of the Radon transform Rf of functions f on general compact Lie groups and introduce two approximate inversion algorithms which utilize our previously developed generalized variational splines on manifolds. Our new algorithms fit very well to the application of Radon transform on SO(3) to texture analysis.

LA DIDATTICA DELL’ITALIANO L2 A DETENUTI STRANIERI
Creators: name: Bonfanti, Valentina
Publisher: name: Italiano LinguaDue
Year: 2012

description: L’insegnamento dell’italiano L2 all’interno degli istituti penitenziari è diventata un’esigenza fondamentale, data la crescente presenza di detenuti stranieri nelle strutture detentive del nostro Paese.Il presente lavoro analizza le peculiarità dell’insegnamento dell’italiano L2 a detenuti stranieri: ruolo e caratteristiche del docente, bisogni e motivazioni dell’apprendente, problematiche legate al contesto specifico di apprendimento. In particolare si intende mettere in evidenza il ruolo primario della scrittura come mezzo fondamentale per svolgere attività quotidiane (padroneggiare regolamenti, richieste, “domandine”) e come strumento per la rieducazione.Per meglio comprendere le specificità dell’insegnamento in questo contesto, viene presentato un sillabo per apprendenti detenuti redatto da Antonella Benucci ed in appendice due interviste rivolte a docenti della Casa Circondariale di Monza.

TEACHING ITALIAN L2 TO FOREIGN INMATES

Teaching Italian L2 in prisons has become a basic need, given the growing number of foreign detainees in Italian prisons.This paper analyzes the peculiarity of teaching Italian L2 to foreign inmates: the teacher’s role and characteristics, the student’s needs and motivations, problems linked to the specific setting. We highlight the primary role of writing as a fundamental means for carrying out daily activities (mastering rules, requests, “small questions”) and as a re-education tool.To better understand the specificity of teaching in this context, a syllabus for detainees compiled by Antonella Benucci is presented and there are two interviews with teachers working in a prison in Monza.

description: We analyze the time pattern of the activity of a serial killer, who during twelve years had murdered 53 people. The plot of the cumulative number of murders as a function of time is of "Devil's staircase" type. The distribution of the intervals between murders (step length) follows a power law with the exponent of 1.4. We propose a model according to which the serial killer commits murders when neuronal excitation in his brain exceeds certain threshold. We model this neural activity as a branching process, which in turn is approximated by a random walk. As the distribution of the random walk return times is a power law with the exponent 1.5, the distribution of the inter-murder intervals is thus explained. We illustrate analytical results by numerical simulation. Time pattern activity data from two other serial killers further substantiate our analysis.

description: One of the most promising proposals for engineering topological superconductivity and Majorana fermions employs a spin-orbit coupled nanowire subjected to a magnetic field and proximate to an s-wave superconductor. When only part of the wire's length contacts to the superconductor, the remaining conducting portion serves as a natural lead that can be used to probe these Majorana modes via tunneling. The enhanced role of interactions in one dimension dictates that this configuration should be viewed as a superconductor-Luttinger liquid junction. We investigate such junctions between both helical and spinful Luttinger liquids, and topological as well as non-topological superconductors. We determine the phase diagram for each case and show that universal low-energy transport in these systems is governed by fixed points describing either perfect normal reflection or perfect Andreev reflection. In addition to capturing (in some instances) the familiar Majorana-mediated `zero-bias anomaly' in a new framework, we show that interactions yield dramatic consequences in certain regimes. Indeed, we establish that strong repulsion removes this conductance anomaly altogether while strong attraction produces dynamically generated effective Majorana modes even in a junction with a trivial superconductor. Interactions further lead to striking signatures in the local density of states and the line-shape of the conductance peak at finite voltage, and also are essential for establishing smoking-gun transport signatures of Majorana fermions in spinful Luttinger liquid junctions.

description: Heisenberg's nonperturbative quantization technique is applied to the nonpertrubative quantization of gravity. An infinite set of equations for all Green's functions is obtained. An approximation is considered where: (a) the metric remains as a classical field; (b) the affine connection can be decomposed into classical and quantum parts; (c) the classical part of the affine connection are the Christoffel symbols; (d) the quantum part is the torsion. Using a scalar and vector fields approximation it is shown that nonperturbative quantum effects gives rise to a cosmological constant and an Euclidean solution.

The Long-Term Evolution of Double White Dwarf Mergers

subject: FOS: Physical sciences

description: In this paper, we present a model for the long-term evolution of the merger of two unequal mass C/O white dwarfs (WDs). After the dynamical phase of the merger, magnetic stresses rapidly redistribute angular momentum, leading to nearly solid-body rotation on a viscous timescale of 1e-4 to 1 yr, long before significant cooling can occur. Due to heating during the dynamical and viscous phases, the less massive WD is transformed into a hot, slowly rotating, and radially extended envelope supported by thermal pressure. Following the viscous phase of evolution, the maximum temperature near the envelope base may already be high enough to begin off-center convective carbon-burning. If not, Kelvin-Helmholtz contraction of the inner region of the envelope on a thermal timescale of 1e3-1e4 yr compresses the base of the envelope, again yielding off-center burning. As a result, the long-term evolution of the merger remnant is similar to that seen in previous calculations: the burning shell diffuses inwards over ~1e4 yr, eventually yielding a high-mass O/Ne WD or a collapse to a neutron star. During the cooling and shell-burning phases, the merger remnant radiates near the Eddington limit. Given the double WD merger rate of a few per 1000 yr, tens of these ~1e38 erg/s sources should exist in a Milky Way-type galaxy. While the end result is similar to that of previous studies, the physical picture and the dynamical state of the matter in our model differ from previous work. Furthermore, remaining uncertainties related to the convective structure near the photosphere and mass loss during the thermal evolution may significantly affect our conclusions. Thus, future work within the context of the physical model presented here is required to better address the eventual fate of double WD mergers, including those for which one or both of the components is a He WD.

description: The setup, capabilities and operation parameters of the neutron reflectometer GINA, the recently installed "Grazing Incidence Neutron Apparatus" at the Budapest Neutron Centre, are introduced. GINA, a dance-floor-type, constant-energy, angle-dispersive reflectometer is equipped with a 2D position-sensitive detector to study specular and off-specular scattering. Wavelength options between 3.2 and 5.7 Å are available for unpolarized and polarized neutrons. Spin polarization and analysis are achieved by magnetized transmission supermirrors and radio-frequency adiabatic spin flippers. As a result of vertical focusing by the five-element (pyrolytic graphite) monochromator the reflected intensity from a 20x20 mm sample has doubled. GINA is dedicated to studies of magnetic films and heterostructures, but unpolarized options for non-magnetic films, membranes and other surfaces are also provided. Shortly after its startup, reflectivity values as low as 3x10-5 have been measured on the instrument. The facility is now open for the international user community, but its development is continuing mainly to establish new sample environment options, the spin analysis of off-specularly scattered radiation and further decrease of the background.

description: Neutron stars are one of the most exotic objects in the universe and a unique laboratory to study the nuclear matter above the nuclear saturation density. In this work, we study the equation of state of the nuclear matter within a relativistic model subjected to a strong magnetic field. We then apply this EoS to study and describe some of the physical characteristics of neutron star, especially the mass-radius relation and chemical compositions. To study the influence of a the magnetic field and the hyperons in the stellar interior, we consider altogether four solutions: two different values of magnetic field to obtain a weak and a strong influence, and two configurations: a family of neutron stars formed only by protons, electrons and neutrons and a family formed by protons, electrons, neutrons, muons and hyperons. The limit and the validity of the results found are discussed with some care. In all cases the particles that constitute the neutron star are in $β$ equilibrium and zero total net charge. Our work indicates that the effect of a strong magnetic field has to be taken into account in the description of magnetars, mainly if we believe that there are hyperons in their interior, in which case, the influence of the magnetic field can increase the mass by more than 10%. We have also seen that although a magnetar can reach 2.48$M_{\odot}$, a natural explanation of why we do not know pulsars with masses above 2.0$M_{\odot}$ arises. We also discuss how the magnetic field affects the strangeness fraction in some standard neutron star masses and, to conclude our paper, we revisit the direct URCA process related to the cooling of the neutron stars and show how it is affected by the hyperons and the magnetic field.

The complexity of change : an interdisciplinary analysis of health care organizations’ responses to ethnic diversity in Vancouver and Montreal
Creators: name: Wylie, Lloy
Publisher: name: University of British Columbia
Year: 2013

description: Research demonstrates that immigrants and racialized populations continue to face notable barriers in accessing health care in Canada. The legislation and public discourse includes multiculturalism, human rights and universal health care, which should be a favourable climate for access; yet research demonstrates it can be challenging for immigrants and ethnically diverse communities to fully exercise those rights. This dissertation explores access barriers through bringing together an analysis of discursive practices in health care and an institutionalist account of responses to facilitating health care access for immigrants and ethnically diverse communities. Both direct attention to local and historical contexts, with health care discourses additionally focusing on the relationships and engagement between health care providers and diverse communities. The aims of this study are to understand the convergence and divergence of framing health care access between health service providers and representatives of immigrant associations, and to explore initiatives to foster access. This research provides a review of Canadian federal and provincial policy on health care, human rights and multiculturalism. I also held interviews with immigrant associations and health service providers in Vancouver and Montreal, who were asked to identify access barriers, and to discuss and assess strategies they are engaged in to address these barriers. The examination of engagement processes provides an exploration of potential sites for change. The dissertation examines processes of engagement between health care service providers and immigrant associations aimed at improving access, and shares participants’ perspectives on the changes attributed to these engagement processes. The data demonstrate that despite a favourable policy climate for ensuring service access, all respondents felt that immigrants face barriers when accessing health care services. Engagement can bring together respective and complementary knowledge of the social contexts, institutional norms and experiences to inform strategies for improving access, although there are additional factors that frame if and how these recommendations are realized at the point of care. The results demonstrate that strategies to address immigrants’ access barriers to health care should take on the structural constraints that shape access, and changes in practices on the ground that address interpersonal relationships between patients and care providers.

description: 3D video can offer real-life viewing experience by providing depth impression. 3D technology has not yet been widely adopted due to challenging 3D-related issues, ranging from capturing to post-processing and display. At the capturing side, lack of guidelines may lead to artifacts that cause viewers headaches and nausea. At the display side, not having 3D content customized to a certain aspect ratio, display size, or display technology may result in reduced quality of experience. Combining 3D with high-dynamic-range imaging technology adds exciting features towards real-life experience, whereas conventional low-dynamic-range content often suffers from color saturation distortion when shown on high-dynamic-range displays. This thesis addresses three important issues on capturing and post-processing 3D content to achieve improved quality of experience. First, we provide guidelines for capturing and displaying 3D content. We build a 3D image and video database with the content captured at various distances from the camera lenses and under different lighting conditions. We conduct comprehensive subjective tests on 3D displays of different sizes to determine the influence of these parameters to the quality of 3D images and videos before and after horizontal parallax adjustment. Next, we propose a novel and complete pipeline for automatic content-aware 3D video reframing. We develop a bottom-up 3D visual attention model that identifies the prominent regions in a 3D video frame. We further provide a dynamic bounding box that crops the video and avoids annoying problems, such as jittering and window violation. Experimental results show that our algorithm is both effective and robust. Finally, we propose two algorithms for correcting saturation in color images and videos. One algorithm uses a fast Bayesian-based approach that utilizes images’ strong spatial correlation and the correlations between the R, G, and B color channels. The other algorithm takes advantage of the strong correlation between the chroma of the saturated pixels and their surrounding unsaturated pixels. Experimental results show that our methods effectively correct the saturated 2D and 3D images and videos. Our algorithms significantly outperform the existing state-of-the-art method in both objective and subjective qualities, resulting in plausible content that resembles real-world scenes.

description: Le scuole reggimentali rappresentano la prima esperienza di insegnamento pubblico dell’italiano ad adulti analfabeti non italofoni, iniziata negli anni a cavallo dell’unificazione e durata sino agli anni settanta del Novecento. Le scuole si proponevano il raggiungimento di obiettivi minimi di alfabetizzazione, in particolare relativi alle attività di lettura e scrittura, servendosi di sillabari e manuali pensati per quel particolare dominio educativo. Con questo articolo si vuole indagare la proposta di alcuni di questi testi, pubblicati nel periodo 1861- 1915, relativamente alle questioni di grafia, ortografia, interpunzione e ortoepia, in quanto prerequisiti fondamentalialle attività più esercitate in queste scuole. Inoltre, l’analisi viene inquadrata nell’ambito delle risorse glottodidattiche coeve per l’insegnamento linguistico nelle scuole primarie e popolari, adottate e rielaborate per queste scuole.

LEARNING TO READ AND WRITE IN REGIMENTAL SCHOOLS (1861-1915)

Regimental public schools were places where illiterate Italian adults and non-native speakers were taught, spanning the time period between Italian unification to the 1970s. These schools aimed at minimal literacy, particularly in reading and writing, through the use of materials and textbooks designed for this particular audience. The article includes samples from textbooks published between 1861 and 1915, with regard to handwriting, spelling, punctuation and pronunciation, considered fundamental requirements for the more advanced activities carried out these schools. The analysis is placed in the framework of contemporary language teaching methods employed in primary and popular schools, which were adopted and revised for regimental teaching.

TWITTER: UN’ANALISI DELL’ITALIANO NEL MICRO BLOGGING

Publisher: name: Italiano LinguaDue

description: Il contributo è incentrato su un’analisi linguistica dell’italiano scritto nella piattaforma sociale e di micro blogging Twitter. Attraverso alcuni esempi estrapolati da un corpus di 2.150 di messaggi, chiamati tweet, si cerca di definire la tipologia testuale e di individuare i tratti sintattici e lessicali salienti del micro blogging. In particolare ci si sofferma su quelle dinamiche micro sintattiche auto generate dall’utenza (@reply, @mention, retweet) e su quei tratti lessicali di organizzazione e costruzione di significato e senso condiviso (hashtag) che concorrono a far emergere, tramite una dinamica “conversazionale - collaborativa” (definita tweetonomy), quella che si potrebbe definire una ”grammatica di Twitter”.

DE QUELQUES NOTIONS INTERESSANT LA REFLEXION SUR LES CURRICULUMS POUR UNE EDUCATION PLURILINGUE ET INTERCULTURELLE.
Creators: name: Coste, Daniel
Publisher: name: Italiano LinguaDue
Year: 2012

description: L’articolo prende in esame alcune nozioni che sono correlate alle opzioni curricolari presentate nella Guida per lo sviluppo e l’attuazione di curricoli per una educazione plurilingue e interculturale del Consiglio d’Europa attraverso anche una rilettura del Quadro comune Europeo di riferimento per le Lingue. Le nozioni sono quelle di competenza, esperienza, mediazione e alterazione. Competenza ed esperienza, considerate come un insieme orientato di capacità, di risorse e di opportunità, rinviano ad acquisizioni e a possibilità di sviluppo degli apprendimenti linguistici e interculturali; a loro volta mediazione e alterazione rinviano ad un processo che conduce ad un risultato. È sugli aspetti linguistici di queste quattro entità nozionali che viene rivolta l’attenzione nella prospettiva di una educazione alla pluralità linguistica e culturale.

SOME INTERESTING IDEAS ON CURRICULUA FOR MULTILINGUAL AND INTERCULTURAL EDUCATION

This article examines some of the notions linked to curriculum options set out in the Guide for the development and implementation of curricula for plurilingual and intercultural education compiled by the Council of Europe based on the European Community Framework of Reference for Languages. The notions considered are competence, experience, mediation and alteration. Competence and experience, inform ability, resources and opportunities, referring to acquisition and the possibility to develop linguistic and intercultural learning; mediation and alteration are linked to a process that leads to a result. Attention is placed on the linguistic aspects of these 4 notions in a perspective of multilingual and multicultural education.
