Year: 2015
Subjects: knowledge society; student services; employment status

description: Education of students is an essential task in the innovated organization of the university missions and it is the most challenging one because, through the formation of knowledge and skills transferred to young graduates, it significantly contributes to the socio-economic and cultural development of territories, contributing to the construction of the knowledge society, at the same time.
The aim of this paper is to analyze the main services that Italian universities offer their students, starting with the essential services to get to those that provide a special care and attention to the educational life of each student. The analysis has been conducted through web browsing and it has allowed to develop an index for the comparison of the universities and their classification according to the services of care and attention reserved for students.

description: We study a ring containing a complete set of orthogonal idempotents as a generalized matrix ring via its Peirce decomposition. We focus on the case where some of the underlying bimodule homomorphisms are zero. Upper and lower triangular generalized matrix rings are pertinent examples of the class of rings which we study. The triviality of the particular bimodule homomorphisms motivates the introduction of three new types of idempotents, namely inner Peirce trivial idempotents, outer Peirce trivial idempotents and Peirce trivial idempotents. These idempotents provide the main tools in our investigations.

description: We study the relationship between a $κ$-Souslin tree $T$ and its reduced powers $T^θ/\mathcal U$. Previous works addressed this problem from the viewpoint of a single power $θ$, whereas here, tools are developed for controlling different powers simultaneously. As a sample corollary, we obtain the consistency of an $\aleph_6$-Souslin tree $T$ and a sequence of uniform ultrafilters $\langle \mathcal U_n\mid n<6\rangle$ such that $ T^{\aleph_n}/\mathcal U_n$ is $\aleph_6$-Aronszajn iff $n<6$ is not a prime number.

Political Behavior of Tirana Electorate

Subjects: ideology; political parties; voting behavior

description: In this study, ideological confusion is focuses mainly on the interdependence reated between the “deeply-social” factors of and political discourse. This analysis focuses on the empirical investigation regarding the perception of Tirana electorate for the relation between the political party structure and ideology, and between electorate and ideology. Based on the survey data, it results that very few people match the profile of a person who can make the distinction between principles of the Left and the Right. The majority of respondents fail to make this distinction or make this distinction but they vote pragmatically. Studies conducted in many countries with consolidated democracy show that both alternatives are possible. So there are several theories explaining the voting behavior, which can help us to understand the survey results and possible factors which affect this voting behavior.: ideology, political parties, voting behavior

Publisher: name: QuiEdit
Year: 2015
Subjects: women theologians; feminism theology; Vatican II Council

description: The essay on “The future of 'women theologians’ in Italy: a sociological analysis” confronts the theme from a theoretical and empirical point of view.  It lingers, at the beginning, on the role of the 'observers women' present at the Vatican II Council and on others who, from the outside, influenced the debate on women, church and modernity. The focus of reflection is on the consequences arising in 'feminist/female theology' today through the data of 'survey' which deals with the universe of Italian Christian women theologians. From a methodical point of view the empiric method used in the survey is a quantitative one by means of a questionnaire with multiple closed. When was feminist theology born? What is the rapport between the genders in the Christian churches? What is the future of women in the Roman Catholic Church and the role of women in the Catholic Church in Italy? What do women theologians think about women priests? What is their 'dream'?  We try to offer a response to these questions.

description: This article, as the first of three, aims at establishing the (time-dependent) Born-Oppenheimer approximation, in the sense of space adiabatic perturbation theory, for quantum systems constructed by techniques of the loop quantum gravity framework, especially the canonical formulation of the latter. The analysis presented here fits into a rather general framework, and offers a solution to the problem of applying the usual Born-Oppenheimer ansatz for molecular (or structurally analogous) systems to more general quantum systems (e.g. spin-orbit models) by means of space adiabatic perturbation theory. The proposed solution is applied to a simple, finite dimensional model of interacting spin systems, which serves as a non-trivial, minimal model of the aforesaid problem. Furthermore, it is explained how the content of this article, and its companion, affect the possible extraction of quantum field theory on curved spacetime from loop quantum gravity (including matter fields).
Care Work between Defamilialization and Commodification

Publisher: name: QuiEdit
Year: 2015
Subjects: family; care; defamilialization

description: The article aims to evaluate the practical possibilities of implementing defamilialization policies in the society of crisis without introducing elements of inequality. At a time of profound changes in the welfare system, labour market and households, defamilialization is presented as a policy that is unsustainable. Starting from a critical reading of the thought of Esping-Andersen, this article stands out as there is no certainty that the virtuous circle of rise in defamilialization-female employment-demand for new services is activated independently from the bottom. At the same time, the hypothesis of defamilialization through the growth of private market services at affordable 'prices' to families is based on a reductive conception of care work, seen only as domestic work and social cost, which would still continue to be a burden to women and would turn the market – at an affordable cost! – into what is already done at home free of charge.

description: This document, titled "D2.1 - Readiness Framework and Service Requirements” is a direct outcome of the UNLOCK-CEI project's work package 2 (WP2), which focuses on designing a framework to address proactively the needs and wants of demand sector about IoT-to-Edge-to-Cloud (CEI) technology as well as to identify the requirements to implement such solutions in specific products and services. Its purpose is to identify key service requirements, develop resulting market scenarios, evaluate key pathways for the development of the open European CEI ecosystem and provide guidance to stakeholders regarding decisions and activities that will improve the chance that favourable scenarios will develop. WP2 provides an analytical framework for the interaction with the sector-specific value chain adopter group representing the Industry Constituency in WP3. This task is focused on developing the CEI adoption readiness framework (ARF), a comprehensive framework with an approach designed to assess the readiness of demand industries for the adoption of Cloud, Edge, and IoT technologies. The framework provides a structured methodology to evaluate various factors and determine the level of preparedness within an industry for embracing these emerging technologies.

description: In this paper we describe a method to solve the linear non-homogeneous fractional differential equations (FDE), composed with Jumarie type Fractional Derivative, and describe this method developed by us, to find out Particular Integrals, for several types of forcing functions. The solutions are obtained in terms of Mittag-Leffler functions, fractional sine and cosine functions. We have used our earlier developed method of finding solution to homogeneous FDE composed via Jumarie fractional derivative, and extended this to non-homogeneous FDE. We have demonstrated these developed methods with few examples of FDE, and also applied in fractional damped forced differential equation. This method proposed by us is useful as it is having conjugation with the classical methods of solving non-homogeneous linear differential equations, and also useful in understanding physical systems described by FDE.

description: Within the framework of the Duffin-Kemmer-Petiau (DKP) formalism a more consistent approach to the derivation of the third order wave equation obtained earlier by M. Nowakowski [Phys.Lett.A {\bf 244} (1998) 329] on the basis of heuristic considerations is suggested. For this purpose an additional algebraic object, the so-called $q$ - commutator ($q$ is a primitive cubic root of unity) and a new set of matrices $η_μ$ instead of the original matrices $β_μ$ of the DKP algebra are introduced. It is shown that in terms of these $η_μ$ matrices we have succeeded in reducing a procedure of the construction of cubic root of the third order wave operator to a few simple algebraic transformations and to a certain operation of the passage to the limit $z \rightarrow q$, where $z$ is some complex deformation parameter entering into the definition of the $η$ - matrices. A corresponding generalization of the result obtained to the case of the interaction with an external electromagnetic field introduced through the minimal coupling scheme is carried out and a comparison with M. Nowakowski's result is performed. A detailed analysis of the general structure for a solution of the first order differential equation for the wave function $ψ(x; z)$ is performed and it is shown that the solution is singular in the $z \rightarrow q$ limit. The application to the problem of construction within the DKP approach of the path integral representation in parasuperspace for the propagator of a massive vector particle in a background gauge field is discussed.

Do Adolescent Peer Smoking Networks Matter for Adults' Smoking Behavior?
Creators: name: Shartle, Kaitlin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Adolescent peers have been shown play an influential role in the initiation of smoking during adolescence. However, there has been limited literature examining whether adolescent peer smoking networks are associated with longer term patterns of smoking. This study uses data from the National Longitudinal Study of Adolescent to Adult Health to examine whether age-based trajectories of daily smoking from adolescence to young adulthood are associated with adolescent peer smoking networks and how these associations differ by gender. Findings using multilevel growth curve models indicate that individuals who have more friends who smoke during adolescence are more likely to be daily smokers. This relationship stays consistent as individuals age. Further analysis shows that these results differ by gender, whereby adolescent peer smoking networks are more strongly associated with smoking in women than men. These findings suggest that adolescent peer smoking networks can have lasting impacts on regular smoking into adulthood.
Prospects of discovering new physics in rare charm decays

description: The LHCb bounds on the branching ratio of rare decay $D^0 \to μ^+ μ^-$ and the constraints on the branching ratio of $D^+ \to π^+ μ^+ μ^-$ in the nonresonant regions enable us to improve constraints on new physics contributions. Using the effective Lagrangian approach we determine sizes of the Wilson coefficients allowed by the existing LHCb bounds on rare charm decays. Then we discuss contributions to rare charm meson decay observables in several models of new physics: a model with an additional spin-1 weak triplet, leptoquark models, Two Higgs doublets model of type III, and a $Z'$ model. Here we complement the discussion by $D^0 - \bar D^0$ oscillations data. Among considered models, only leptoquarks can significantly modify Wilson coefficients. Assuming that the differential decay width for $D^+ \to π^+ μ^+ μ^-$ receives NP contribution, while the differential decay width for $D^+ \to π^+ e^+ e^-$ is Standard Model-like, we find that lepton flavor universality can be violated and might be observed at high dilepton invariant mass.

Maurice Halbwachs: Classical Sociology after the Classics
Creators: name: Migliorati, Lorenzo
Publisher: name: QuiEdit
Year: 2015
Subjects: Maurice Halbwachs; sociological theory; collective psychology

description: The paper sets out to analyse the scientific production of Maurice Halbwachs (1877-1945). If in France he is substantially considered a classic to study, to publish and to republish, in other countries – in Europe, as in the United States – he is considered a lesser author, an epigone of Durkheim, though he was never even a direct alumnus of the latter. To me it seems, instead, that there is more than one reason why sociology should rediscover this figure, regarding both the theoretical aspect and that of empirical research.
First. Halbwachs is rightly known for his studies on collective memory; and, in effect, these are pioneering and courageous works that have involved enormous gains for the sociological discipline in epistemological terms. Nevertheless, he is unjustly little known as concerns the many other themes that he dealt with.
Second. Halbwachs’ sociological posture starts from Durkheimian organicism, but never slavishly bows to it. In this sense, it seems me that the true hidden pearl of this author lies in his conception of social reality as of a dialectical and constant tension between society and individual.

description: In this article, the second of three, we discuss and develop the basis of a Weyl quantisation for compact Lie groups aiming at loop quantum gravity-type models. This Weyl quantisation may serve as the main mathematical tool to implement the program of space adiabatic perturbation theory in such models. As we already argued in our first article, space adiabatic perturbation theory offers an ideal framework to overcome the obstacles that hinder the direct implementation of the conventional Born-Oppenheimer approach in the canonical formulation of loop quantum gravity. Additionally, we conjecture the existence of a new form of the Segal-Bargmann-Hall "coherent state" transform for compact Lie groups $G$, which we prove for $G=U(1)^{n}$ and support by numerical evidence for $G=SU(2)$. The reason for conjoining this conjecture with the main topic of this article originates in the observation, that the coherent state transform can be used as a basic building block of a coherent state quantisation (Berezin quantisation) for compact Lie groups $G$. But, as Weyl and Berezin quantisation for $\mathbb{R}^{2d}$ are intimately related by heat kernel evolution, it is natural to ask, whether a similar connection exists for compact Lie groups, as well. Moreover, since the formulation of space adiabatic perturbation theory requires a (deformation) quantisation as minimal input, we analyse the question to what extent the coherent state quantisation, defined by the Segal-Bargmann-Hall transform, can serve as basis of the former.

description: Cosmic voids are a promising environment to characterize neutrino-induced effects on the large-scale distribution of matter in the universe. We perform a comprehensive numerical study of the statistical properties of voids, identified both in the matter and galaxy distributions, in massive and massless neutrino cosmologies. The matter density field is obtained by running several independent $N$-body simulations with cold dark matter and neutrino particles, while the galaxy catalogs are modeled by populating the dark matter halos in simulations via a halo occupation distribution (HOD) model to reproduce the clustering properties observed by the Sloan Digital Sky Survey (SDSS) II Data Release 7. We focus on the impact of massive neutrinos on the following void statistical properties: number density, ellipticities, two-point statistics, density and velocity profiles. Considering the matter density field, we find that voids in massive neutrino cosmologies are less evolved than those in the corresponding massless neutrinos case: there is a larger number of small voids and a smaller number of large ones, their profiles are less evacuated, and they present a lower wall at the edge. Moreover, the degeneracy between $σ_8$ and $Ω_ν$ is broken when looking at void properties. In terms of the galaxy density field, we find that differences among cosmologies are difficult to detect because of the small number of galaxy voids in the simulations. Differences are instead present when looking at the matter density and velocity profiles around these voids.

Pulsation-driven mean zonal and meridional flows in rotating massive stars

description: Zonal and meridional axisymmetric flows can deeply impact the rotational and chemical evolution of stars. Therefore, momentum exchanges between waves propagating in stars, differential rotation, and meridional circulation must be carefully evaluated. In this work, we study axisymmetric mean flows in rapidly and initially uniformly rotating massive stars driven by small amplitude non-axisymmetric $κ$-driven oscillations. We treat them as perturbations of second-order of the oscillation amplitudes and derive their governing equations as a set of coupled linear ordinary differential equations. This allows us to compute 2-D zonal and meridional mean flows driven by low frequency $g$- and $r$-modes in slowly pulsating B (SPB) stars and $p$-modes in $β$ Cephei stars. Oscillation-driven mean flows usually have large amplitudes only in the surface layers. In addition, the kinetic energy of the induced 2-D zonal rotational motions is much larger than that of the meridional motions. In some cases, meridional flows have a complex radial and latitudinal structure. For SPB stars, we find that there are low frequency retrograde $g$-modes and $r$-modes that drive mean flows with positive velocity components in the radial and azimuthal directions at the stellar surface. This suggests that low frequency retrograde modes can transport angular momentum to the surface layers, which may help to form a circumstellar gaseous disc. Moreover, pulsation-driven and rotation-driven meridional flows can have similar amplitudes. These results show the importance of taking wave-- mean flow interactions into account when studying the evolution of massive stars.

Distant set distinguishing total colourings of graphs

subject: 05C15

description: The Total Colouring Conjecture suggests that $Δ+3$ colours ought to suffice in order to provide a proper total colouring of every graph $G$ with maximum degree $Δ$. Thus far this has been confirmed up to an additive constant factor, and the same holds even if one additionally requires every pair of neighbours in $G$ to differ with respect to the sets of their incident colours, so called pallets. Within this paper we conjecture that an upper bound of the form $Δ+const.$ still remains valid even after extending the distinction requirement to pallets associated with vertices at distance at most $r$, if only $G$ has minimum degree $δ$ larger than a constant dependent on $r$. We prove that such assumption on $δ$ is then unavoidable and exploit the probabilistic method in order to provide two supporting results for the conjecture. Namely, we prove the upper bound $(1+o(1))Δ$ for every $r$, and show that the conjecture holds if $δ\geq \varepsilonΔ$ for any fixed $ε\in(0,1]$ and $r$, i.e., in particular for regular graphs.

Quantum Discord of Cosmic Inflation: Can we Show that CMB Anisotropies are of Quantum-Mechanical Origin?

description: We investigate the quantumness of primordial cosmological fluctuations and its detectability. The quantum discord of inflationary perturbations is calculated for an arbitrary splitting of the system, and shown to be very large on super-Hubble scales. This entails the presence of large quantum correlations, due to the entangled production of particles with opposite momentums during inflation. To determine how this is reflected at the observational level, we study whether quantum correlators can be reproduced by a non-discordant state, i.e. a state with vanishing discord that contains classical correlations only. We demonstrate that this can be done for the power spectrum, the price to pay being twofold: first, large errors in other two-point correlation functions and second, the presence of intrinsic non-Gaussianity. The detectability of these two features remains to be determined but could possibly rule out a non-discordant description of the cosmic microwave background. If one abandons the idea that perturbations should be modeled by quantum mechanics and wants to use a classical stochastic formalism instead, we show that any two-point correlators on super-Hubble scales can be exactly reproduced regardless of the squeezing of the system. The latter becomes important only for higher-order correlation functions that can be accurately reproduced only in the strong squeezing regime.

description: The latest Planck results show a power deficit in the temperature anisotropies near $\ell \approx 20$ in the cosmic microwave background (CMB). This observation can hardly be explained within the standard inflationary $Λ$-cold-dark-matter ($Λ$CDM) scenario. In this paper we consider a string theory inspired inflationary model (axion monodromy inflation) with a step-like modulation in the potential which gives rise to observable signatures in the primordial perturbations. One interesting phenomenon is that the primordial scalar modes experience a sudden suppression at a critical scale when the modulation occurs. By fitting to the CMB data, we find that the model can nicely explain the $\ell \approx 20$ power deficit anomaly as well as predict specific patterns in the temperature-polarization correlation and polarization autocorrelation spectra. Though the significance of the result is not sufficient to claim a detection, our analysis reveals that fundamental physics at extremely high energy scales, namely, some effects inspired by string theory, may be observationally testable in forthcoming cosmological experiments.

description: Peak counts have been shown to be an excellent tool to extract the non-Gaussian part of the weak lensing signal. Recently, we developped a fast stochastic forward model to predict weak-lensing peak counts. Our model is able to reconstruct the underlying distribution of observables for analyses. In this work, we explore and compare various strategies for constraining parameter using our model, focusing on the matter density $Ω_\mathrm{m}$ and the density fluctuation amplitude $σ_8$. First, we examine the impact from the cosmological dependency of covariances (CDC). Second, we perform the analysis with the copula likelihood, a technique which makes a weaker assumption compared to the Gaussian likelihood. Third, direct, non-analytic parameter estimations are applied using the full information of the distribution. Fourth, we obtain constraints with approximate Bayesian computation (ABC), an efficient, robust, and likelihood-free algorithm based on accept-reject sampling. We find that neglecting the CDC effect enlarges parameter contours by 22%, and that the covariance-varying copula likelihood is a very good approximation to the true likelihood. The direct techniques work well in spite of noisier contours. Concerning ABC, the iterative process converges quickly to a posterior distribution that is in an excellent agreement with results from our other analyses. The time cost for ABC is reduced by two orders of magnitude. The stochastic nature of our weak-lensing peak count model allows us to use various techniques that approach the true underlying probability distribution of observables, without making simplifying assumptions. Our work can be generalized to other observables where forward simulations provide samples of the underlying distribution.

description: The quality of requirements engineering artifacts is widely considered a success factor for software projects. Currently, the definition of high-quality or good RE artifacts is often provided through normative references, such as quality standards, textbooks, or generic guidelines. We see various problems of such normative references: (1) It is hard to ensure that the contained rules are complete, (2) the contained rules are not context-dependent, and (3) the standards lack precise reasoning why certain criteria are considered bad quality. To change this understanding, we postulate that creating an RE artifact is rarely an end in itself, but just a means to understand and reach the project’s goals. Following this line of thought, the purpose of an RE artifact is to support the stakeholders in whatever activities they are performing in the project. This purpose must define high-quality RE artifacts. To express this view, we contribute an activity-based RE quality meta model and show applications of this paradigm. Lastly, we describe the impacts of this view onto research and practice.

description: This article reviews the research on the unique challenges of interpreting in technical fields and the specialized skills interpreters must develop. Methods include a literature review of studies on interpreting in various technical domains and analysis of professional interpreter training programs. The results show that interpreters in specialized fields must possess in-depth knowledge of domain-specific terminology, concepts, and practices in both the source and target languages and cultures. Additionally, they need strong research and analytical skills to quickly get up to speed on new topics.

description: In this article, the third of three, we analyse how the Weyl quantisation for compact Lie groups presented in the second article of this series fits with the projective-phase space structure of loop quantum gravity-type models. Thus, the proposed Weyl quantisation may serve as the main mathematical tool to implement the program of space adiabatic perturbation theory in such models. As we already argued in our first article, space adiabatic perturbation theory offers an ideal framework to overcome the obstacles that hinder the direct implementation of the conventional Born-Oppenheimer approach in the canonical formulation of loop quantum gravity.

finite population

description: The self-organization of collective behaviour is a topic of interest in numerous research fields, and in its context, evolutionary game theory has proved to be a powerful probing tool. Even though initial evolutionary models with frequency- dependent fitness assumed infinite populations, it has been shown that the stability of a strategy may depend not only on the game's payoff matrix but on the size of the finite population. To perform a systematic analysis of 2x2 games in well-mixed finite populations, we start by proving that 9 of the 24 possible payoff orderings always lead to single mutant fixation probability functions decreasing monotonically with population size as they trivially do under fixed fitness scenarios. However, we observe a diversity of fixation functions with increasing regions under 12 other orderings, which included anti-coordination games (e.g. Hawk-Dove/Snowdrift game), the fixation of unbeatable strategies (e.g. Defectors in the Prisoner’s Dilemma), and the fixation of Stag Hunters under that game (the only exception in coordination games). Fixation functions that increase from a global minimum up to a finite asymptotic value are pervasive, and we suggest that these have been easily concealed by the weak selection limit. We prove under which payoff matrices it is possible to have fixation increasing for the smallest populations and find three different ways this can happen. Finally, we describe two distinct fixation functions having two local extremes and associate them with transitions from ones with one global minimum.

description: We investigated the spatial distribution of quantum fluctuations in a squeezed vacuum field, generated via polarization self-rotation (PSR) interaction of an ensemble of Rb atoms and a strong near-resonant linearly polarized laser field. We found that the noise suppression is greatly effected by the transverse profile of a spatial mask, placed in both the squeezed field and the local oscillator, as well as its position along the focused beam near the focal point. These observations indicate the spatial multi-mode structure of the squeezed vacuum field. We have developed a theoretical model that describes the generation of higher-order Laguerre-Gauss modes as a result of PSR light-atom interaction. The prediction of this model are in a good qualitative agreement with the experimental measurements.

Subjects: breast cancer; grounded theory; biographical disruption

description: Breast cancer is a severe disease, which in combination with mastectomy poses particular psychosocial problems. After mastectomy, once the threat to life has been dealt with, intense psychosocial processes are caused to the woman who is trying to come in terms with the new body image, creating a new concept for themselves and their social identity, as women, mothers and companions. The woman’s breast is connected with sexuality as well as motherhood and thus, mastectomy problematizes the very foundations of female identity. The goal of this research is to prove, through biographical interview, the lived experience of breast cancer utilizing the meaning of biographical disruption. This paper presents critical remarks for a qualitative research, in order to record with reliability the way women rearrange their life, reconstructing their identity after mastectomy. We suggest the use of narrative method, combined with a research planning based on Grounded theory and the meaning of “biographical disruption”.

The Spaces of Resilience: Learning and Adaption

description: “To succeed in the modern economy you need technical and adaptive skills. Technical skills and specialized knowledge makes you a more efficient and productive worker, but it can lock you in to a part of the division of labor that can disappear over night in the winds of creative destruction that increasingly sweep across the economy. Across both natural and human systems, processes that increase the efficient production of wealth and stored energy undermine resilience” (Swanstrom, 2008: 6-7). In fact, at a time of crisis it seems that the territories are even more vulnerable and fragile: emerging social issues (like new poverty), new needs, frayed social fabrics and lack of social networks. This syndrome of weakness can be remedied only if the collective intelligence of an area tries to develop development policies for education and culture of legality, stimulating 'communities of practices' and investing in intangible factors of development. A successful economy creates tight connections between the industry, society and the government (e.g. Triple Helix Model) but these same connections can make difficult to shift public policies and redeploy assets in the face of a crisis (Safford 2004). Similarly, lean companies with just-on-time production and global supply chains, may be highly efficient but they are vulnerable to disruptions (Sheffi, 2007).
This paper analyzes the mechanisms of adaptation and self-organization to promote resilience; particularly, after describing the relationship between risk, resilience and sustainability, we have focused on the ecological model of resilience that reconciles the  contradiction mentioned above through the idea of panarchy that captures the “evolutionary nature of adaptive cycles that are nested one within each other across space and time” (Holling, 2001: 396).
