description: Summary: - Situated in the Chadian Sahel, in the Lake Chad basin, Hadjer Lamis is one of the 23 provinces of Chad. It has surface and underground water potential, and very rich arable land, particularly that resulting from the flooding and ebbing of the waters of the arms of Lake Chad. This land is farmed by market gardeners in Mani canton, some 100 km from N'Djamena, the capital of Chad. The aim of the study is to analyze the production and marketing of market garden produce in the Hadjer lami: the example of Mani township. Using documentary consultations, a questionnaire survey, interviews and direct observations in the villages of Douguia, Mani, Guitté and Miteriné, we arrived at the following results. Production is made possible firstly by the availability and fertility of the land, which can be accessed by inheritance (45%), free grant (32%), lease (10%) and others (13%), then by the availability of underground water, tapped by borehole (42%), water from the Chari (38%), and finally rainwater (20%).  Market garden production is carried out by a diverse population, dominated by Arabs (25%), Haoussa (20%), Foulbé (13%) and Foulata (10%). Despite production constraints such as destruction of crops by insects and birds, access to inputs, etc., production is assured and intended not only for feeding the population, but also for the environment.

description: We consider the linear equation of state for matter distributions that may be applied to strange stars with quark matter. In our general approach the compact relativistic body allows for anisotropic pressures in the presence of the electromagnetic field. New exact solutions are found to the Einstein-Maxwell system. A particular case is shown to be regular at the stellar centre. In the isotropic limit we regain the general relativistic isothermal universe. We show that the mass corresponds to values obtained previously for quark stars when anisotropy and charge are present.

Thermal Behavior of Spin Clusters and Interfaces in two-dimensional Ising Model on Square Lattice

Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Extensive Monte Carlo study of two-dimensional Ising model is done to investigate the statistical behavior of spin clusters and interfaces as a function of temperature, $T$. We use a \emph{tie-breaking} rule to define interfaces of spin clusters on square lattice with strip geometry and show that such definition is consistent with conformal invariant properties of interfaces at critical temperature, $T_c$. The \emph{effective} fractal dimensions of spin clusters and interfaces ($d_c$ and $d_I$, respectively) are obtained as a function of temperature. We find that the effective fractal dimension of the spin clusters behaves almost linearly with temperature in three different regimes. It is also found that the effective fractal dimension of the interfaces undergoes a sharp crossover around $T_c$, between values 1 and 1.75 at low and high temperatures, respectively. We also check the finite-size scaling hypothesis for the percolation probability and the average mass of the largest spin-cluster in a good agreement with the theoretical predictions.

description: [On the curious paradox of Bernard Mandeville: private vices, public benefits.] The fable of the bees by Bernand de Mandeville is a satirical poem in which vice is praised for its function in achieving economic, social, and moral prosperity. The large commercial companies of the modern era are forced to abandon the nostalgic references to the golden age in which simplicity, frugality, and individual virtues contributed to the collective well-being. The proliferation of needs and diffusion of vices guide economic and political action that prefers to observe men as they are rather than as they should be.
The Digital Resistance: Contesting the Power of Gig Economy Platforms through Collective Worker Action
Creators: name: Forsyth, Anthony
Publisher: name: Italian Labour Law e-Journal
Year: 2023

description: This article examines how trade unions and self-organised worker groups have deployed digital organising tools to collectivise gig work, focusing on rideshare and food delivery platforms. It demonstrates the successful actions of worker representatives to improve the working conditions and legal position of platform-based rideshare and food delivery workers in several countries, through: coordinated mobilisation to disrupt the operations of platforms and build campaigns for increased regulation of platform work; strategic litigation to establish useful legal precedents, attract public attention and build solidarity among like-minded workers; and negotiating collective agreements on behalf of gig workers. While deficiencies are identified in the collective bargaining activities of some unions, the article concludes that unions and grass-roots worker groups have played a critical role in contesting the contracting model which lies at the core of gig worker exploitation – and helping them to martial the power obtained through resistance and collective action.

Slow Approval Process of the Due Diligence Directive and the Different Paths for the Involvement of Trade Unions
Creators: name: Cordella, Costantino
Publisher: name: Italian Labour Law e-Journal
Year: 2023

description: In this article, we highlight the different positions expressed by the European Parliament and the European Commission on the need to provide for the involvement of trade unions in the new directive on Company Due Diligence. The Parliament's position tends to emphasize the importance of prior consultation with trade unions. In the opposite direction, the European Commission's draft directive, from a management perspective, understands due diligence compliance as a governance constraint decided unilaterally by companies. Considering these processes, we try to ask whether trade unions can autonomously contribute to the ecological transition of companies and the protection of human rights, considering the advantages and disadvantages of their involvement.

title: The Limits of Control : Transnational Migration Trajectories of Clandestine Tunisian Migrants and Assisted Return Between Governed Voluntariness and Repression
Creators: name: Loher, David
Publisher: name: Universität Bern
Year: 2021
Subjects: subject: 300 Social sciences, sociology & anthropology

description: The Limits of Control takes Switzerland’s programme for assisted voluntary return migration (AVR) as an example to study the emerging contradictions of the sovereign liberal nation state in the governance of transnational mobility. The aim to remove the “undesirable alien” from the commonwealth governed by the state bureaucracy produces a fundamental problem for the liberal nation state as it questions the bureaucracy’s universal promise of equality and fairness.

The ethnographic case study focuses on Switzerland’s AVR programme for Tunisian asylum seekers after the 2011 uprising against the Ben Ali regime and shows how the migration bureaucracy produces, shapes, and governs migrants’ “voluntariness.” It is based on ethnographic fieldwork among return migrants and return migration bureaucrats in Tunisia and Switzerland in 2013 and 2014. The paradoxical notion of governed voluntariness serves as the analytical lens to explore the efforts of the migration bureaucracy to reconcile the attempts to anticipate and enforce negative asylum decisions with the bureaucratic selfunderstanding of a governance by mutual consent. Therefore, The Limits of Control tells the story of the failing attempt to uphold the illusion of governing transnational migration by mutual consent creating a so-called win-win-win situation for the country of origin, the country of destination, and the migrant as well.

Adopting the thesis of the autonomy of migration AoM as an analytical proposition, the ethnography confronts the experiences and expectations of mobility and return of six Tunisian migrants of different age and origin with the attempts of Switzerland’s migration bureaucracy to regulate migrants’ mobility through AVR programs. Therefore, this study exemplarily shows how these contested controls at the margins of the state (of undocumented migration) contradict the modern liberal nation state’s self-understanding of a governance by mutual consent.

description: The technologies of quantum information and quantum control are rapidly improving, but full exploitation of their capabilities requires complete characterization and assessment of processes that occur within quantum devices. We present a method for characterizing, with arbitrarily high accuracy, any quantum optical process. Our protocol recovers complete knowledge of the process by studying, via homodyne tomography, its effect on a set of coherent states, i.e. classical fields produced by common laser sources. We demonstrate the capability of our protocol by evaluating and experimentally verifying the effect of a test process on squeezed vacuum.

New (work) environments in the wake of the reform of Articles 9 and 41 of the Italian Constitution: what prospects for the employers’ preventive obligations?
Creators: name: Giovannone, Maria
Publisher: name: Italian Labour Law e-Journal
Year: 2023

description: Among the most critical issues in the ongoing doctrine and jurisprudence debate are those that concern (i) employer responsibility for occupational health and safety in connection with new jobs and (ii) emerging risks associated with new ways of performing work. This debate has recently been amplified by the new concept of ‘work environment’, which, according to some authors, now also includes the company’s external environment due to the reform of Articles 9 and 41 of the Constitution. In fact, with the explicit introduction of the obligation to protect the environment and the principle of sustainability in Article 41 of the Constitution, it is appropriate to reflect on the possibility of remodelling the prevention obligations and reinterpreting the employers’ safety obligation in view of sustainability. The paper addresses the issue of the role of the firm in environmental policies: promotion and accountability with the dual perspective of a theoretical analysis and discussion paper. In the wake of the experience already gained by collective bargaining and participation techniques in occupational health and safety, the paper will first look at the extension of the preventive obligation and the related criminal liability to the external environment, and then focus on the new perspectives of negotiated regulation of this obligation.

Measuring the Knowledge Base of an Economy in terms of Triple-Helix Relations among 'Technology, Organization, and Territory'

description: Can the knowledge base of an economy be measured? In this study, we combine the perspective of regional economics on the interrelationships among technology, organization, and territory with the triple-helix model, and offer the mutual information in three dimensions as an indicator of the configuration. When this probabilistic entropy is negative, the configuration reduces the uncertainty that prevails at the systems level. Data about more than a million Dutch companies are used for testing the indicator. The data contain postal codes (geography), sector codes (proxy for technology), and firm sizes in terms of number of employees (proxy for organization). The configurations are mapped at three levels: national (NUTS-1), provincial (NUTS-2), and regional (NUTS-3). The levels are cross-tabled with the knowledge-intensive sectors and services. The results suggest that medium-tech sectors contribute to the knowledge base of an economy more than high-tech ones. Knowledge-intensive services have an uncoupling effect, but less so at the high-tech end of these services.

On the convergence of the Gauss-Seidel method applied to Dirichlet difference problems over various types of regions.
Creators: name: Teng, Koit
Publisher: name: University of British Columbia
Year: 2011

description: The main problem considered is the effect due to changes in the shape of the region on the convergence rate of the Gauss-Seidel iterative method for solving the Dirichlet Difference Problem. Experimentally, it is found that as a rule the number of iterations required to attain convergence decreases as the perimeter of the region is increased. The ensuing theoretical investigation leads to the examination of the corresponding iteration matrices and a qualitative theory results which predicts that the number of iterations should increase with the number of nonzero off - diagonal elements in the matrix of the linear system. Further experiments indicate that the latter relationship is no more precise than the former; the lack of rigour in the theory is undoubtedly to blame. Better results, are obtained in the sub-problem of estimating the number of iterations necessary to satisfy a suitable convergence criterion, given a good estimate of the spectral radius of the iteration matrix corresponding to the region under study.

description: Whether a dwarf spheroidal galaxy is in equilibrium or being tidally disrupted by the Milky Way is an important question for the study of its dark matter content and distribution. This question is investigated using 328 recent observations from the dwarf spheroidal Leo I. For Leo I, tidal disruption is detected, at least for stars sufficiently far from the center, but the effect appears to be quite modest. Statistical tools include isotonic and split point estimators, asymptotic theory, and resampling methods.

Year: 2023

description: This study investigates the Leader Member Exchange (LMX) model and job satisfaction for employees working remotely during the COVID-19 pandemic. The research is based on 22 semi-structured interviews conducted with consultants on different career levels within a multinational corporation (MNC) in 2022. The results indicate that the shift to remote work, during the COVID-19 pandemic, has brought new considerations to the LMX model and job satisfaction. In addition, it also positively impacted economic, environmental, and social sustainability goals. The qualitative study identifies three aggregated key factors, conducted from the interview data, that contribute to job satisfaction in a remote work setting: (1) methods of collaboration, (2) performing through collaboration, and (3) identification with work and employer. These findings offer valuable insight on remote working during the COVID-19 pandemic. They also provide a foundation for further research on remote and hybrid work and collaboration models, whilst providing understanding on their alignment to economic, environmental, and social sustainability goals.

description: [On the Sources of Inspiration of the Jurist between Politics and Law. Insights in “other” narratives] The paper focuses on the wide range of sources of inspiration underlying the work of the jurist between politics and law. Starting from the relevant role played by literature within the legal dimension, which has been put in light by the so-called orientation Law and Literature, the analysis deals with the reference to “other” narratives through some examples related to the modernity as well as to the recent and contemporary scenario. Concerning the first one, the ambiguity of Hobbes’ legal-political perspective paradigmatically emerges in order to understand the implementation of the modern political-legal model. In the same way, the current scenario is deepened both in light of some obscure or contradictory aspects of the National Socialism and of some aspects concerning the “case Dugin” closely connected to the conflict Russia-Ukraina. In conclusion, the contribution focuses on the modern conceptual architecture of the political-legal sphere: moving from the relevant role played by “other” narratives, it allows the rethinking of some fundamental legal categories dating back to the origins of modernity.

description: The limacon-shaped semiconductor microcavity is a ray-chaotic cavity sustaining low-loss modes with mostly unidirectional emission patterns. Investigating these modes systematically, we show that the modes correspond to ray description collectively, rather than individually. In addition, we present experimental data on multimode lasing emission patterns that show high unidirectionality and closely agree with the ray description. The origin of this agreement is well explained by the collective correspondence mechanism.

description: Pion condensation is studied at one--loop level and nonzero baryochemical potential in the framework of two flavor constituent quark model using the one--loop level optimized perturbation theory for the resummation of the perturbative series. A Landau type of analysis is presented for the investigation of the phase boundary between the pion condensed/non-condensed phases. The statement that the condensation starts at $\muI = m_π$ is slightly modified by one--loop corrections. The second order critical surface is determined and analysed in the $\muI-\muB-T$ space. The $\muI$ dependence of the one--loop level charged pion pole masses is also studied.

description: The aggregated citation relations among journals included in the Science Citation Index provide us with a huge matrix which can be analyzed in various ways. Using principal component analysis or factor analysis, the factor scores can be used as indicators of the position of the cited journals in the citing dimensions of the database. Unrotated factor scores are exact, and the extraction of principal components can be made stepwise since the principal components are independent. Rotation may be needed for the designation, but in the rotated solution a model is assumed. This assumption can be legitimated on pragmatic or theoretical grounds. Since the resulting outcomes remain sensitive to the assumptions in the model, an unambiguous classification is no longer possible in this case. However, the factor-analytic solutions allow us to test classifications against the structures contained in the database. This will be demonstrated for the delineation of a set of biochemistry journals.

description: The very recent years have seen a promising start in scientific publications making use of images produced by near-infrared long-baseline interferometry. The technique has reached, at last, a technical maturity level that opens new avenues for numerous astrophysical topics requiring milli-arcsecond model-independent imaging. The Very Large Telescope Interferometer (VLTI) is on the path to be equipped with instruments capable to combine between four to six telescopes. In the framework of the VLTI second generation instruments Gravity and VSI, we propose a new beam combining concept using Integrated Optics (IO) technologies with a novel ABCD-like fringe encoding scheme. Our goal is to demonstrate that IO-based combination brings considerable advantages in terms of instrumental design and performance. We therefore aim at giving a full characterization of an IO beam combiner to establish its performances and check its compliance with the specifications of an imaging instrument. Laboratory measurements were made in the H band with a dedicated testbed. We studied the beam combiners through the analysis of throughput, instrumental visibilities, phases and closure phases in wide band as well as with spectral dispersion. Study of the polarization properties is also done. We obtain competitive throughput, high and stable instrumental contrasts, stable but non-zero closure phases which we attribute to internal well calibrable optical path differences. We validate a new static and achromatic phase shifting IO function close to the nominal 90deg value. All these observables show limited chromaticity over the H band range. Our results demonstrate that such ABCD-like beam combiners are particularly well suited to achieve aperture synthesis imaging. This opens the way to extend to all near infrared wavelengths and in particular, the K band.

description: We present 5 to 15 micron Spitzer Infrared Spectrograph (IRS) low resolution spectral data of a candidate debris disk around an M4.5 star identified as a likely member of the ~40 Myr old cluster NGC2547. The IRS spectrum shows a silicate emission feature, indicating the presence of warm, small, (sub)micron-sized dust grains in the disk. Of the fifteen previously known candidate debris disks around M-type stars, the one we discuss in this paper is the first to have an observed mid-infrared spectrum and is also the first to have measured silicate emission. We combined the IRS data with ancillary data (optical, JHKs, and Spitzer InfraRed Array Camera and 24 micron data) to build the spectral energy distribution (SED) of the source. Monte Carlo radiation transfer modeling of the SED characterized the dust disk as being very flat (h100=2AU) and extending inward within at least 0.13AU of the central star. Our analysis shows that the disk is collisionally dominated and is likely a debris disk.

By utilizing autoethnography, creative writing and expression, and plans for oral interviewing, my project seeks to heal historical traumas of forced displacement that has shaped the Hmong diasporic consciousness—what do we gain when we choose to love each day despite deeply-rooted traumas that transposes itself across time and space, causing for the re-living of trauma rather than its remembrance? How do we exchange the tools of love to transform each other towards our own rescue? This research serves as a source in which love, sexuality, and Hmongness, blend, and how we can extrapolate examples of love, and lessons learned from love within these oral interviews, into centering a love ethic within our daily lives.

description: This report presents the preliminary results of the performances of a prototype of a silicon tungsten calorimeter, which has been conceived as a high-granularity tracking calorimeter for cosmic ray studies. The calorimeter contains 20 XY sampling planes interleaved with 19 showering material planes (W, 0.5 X_0 = 1.75 mm). One sensitive plane is obtained two silicon strip detectors (Si-D) (60 x 60) mm^2 divided in 16 strips 3.6 mm wide. The strips of the two detectors are perpendicular to each other in order to provide the transverse distributions in both coordinates at each sampling. The basic characteristics of the design and the first experimental results obtained at a test beam at CERN PS for 2, 4 and 6 GeV electrons and pions are reported. The main results here presented are: the response of the calorimeter to the electron energies, the transverse shower profiles at different calorimeter depths as well as the patterns of the electron induced electromagnetic shower and those of the interating and non interating pions. The angular resolution has been measured for electron showers at 4 GeV. The calorimeter performances and the adopted design criteria are also considered for possible applications to preshower detectors.

description: Comparative studies have shown that the eye morphology of primates has been shaped by a variety of selection pressures (e.g. communication, environmental factors). To comprehensively elucidate the complex links between ocular morphology and its evolutionary drive, attention should be paid to other phylogenetic groups. Here, we address a new question regarding the evolution of eye colour patterns in the oldest domesticated animal, namely, the domestic dog (Canis familiaris). In this study, we conducted an image analysis of dogs and their closest relatives, grey wolves (Canis lupus), to compare the colours of their irises, with the aim of assessing whether eye colours of dogs affect how humans perceived dogs. We found that the irises of dogs were significantly darker than those of wolves. We also found that facial images of dark-eyed dogs were perceived as more friendly and immature, potentially eliciting caregiving responses from humans. Our findings are consistent with our expectation that humans favour dark-eyed dogs over light-eyed ones and provide an updated hypothesis that dogs with dark eyes may have evolved by acquiring a facial trait that sends a non-threatening gaze signal to humans.
MASS GENERATION IN THE STANDARD MODEL
Creators: name: SHE-SHENG XUE
Publisher: name: INFN Open Access Repository
Year: 1992

description: A proposal of mass generation in the Standard Model (SM) is presented, based on the idea that the violent fluctuations of quantum gravity at the Planck scale plays a nature regulator for the SM with fundamental length a_p∼10^-33cm, thus gauge invariant four-interactions are necessary due to the 'no-go' theorem of Nielsen and Ninomiya, forbidding a sensible formulation of the usual electroweak action on a such 'Planck lattice'. We present that for certain values of the new four-fermion couplings a spontaneous violation of SM chiral symmetry emerges which (i) avoids the 'no-go' theorem, (ii) produces a t ̅t condensate model without appearance of the low-energy Higgs boson. The mass generation of other fermions and intermediate gauge bosons, are briefly discussed.

Anno Accademico: 2018-2019

Relatore: Giovanni Ragone

Questa tesi analizza come Internet, con il suo potenziale tecnologico e comunicativo, abbia trasformato profondamente tre arti performative: il cinema, il teatro e la musica. Attraverso tre casi di studio emblematici, l’autrice esplora l’intersezione tra media digitali e linguaggi artistici, mostrando come il mezzo influenzi il contenuto e la fruizione culturale.

• Cinema: L’analisi si concentra su Eva.Stories, un progetto innovativo che utilizza le Stories di Instagram per raccontare la memoria storica dell’Olocausto attraverso un linguaggio moderno e accessibile ai giovani.

• Teatro: Viene discusso lo spettacolo Innovating Colosseo, un esempio di performance teatrale distribuita supportata da tecnologie avanzate come la rete GARR e la fibra ottica, che abbatte la quarta parete e rende possibile l’interattività.

• Musica: Viene esplorato il ruolo dell’Intelligenza Artificiale di Spotify, che influenza i gusti musicali degli utenti e crea esperienze di ascolto personalizzate, aprendo nuove strade per la creazione musicale.

Title: When the Internet Becomes a Show: Cinema, Theater, Music - Three Case Studies

Author: Gabriella Paolini

Academic Year: 2018-2019

Advisor: Giovanni Ragone

This thesis investigates how the Internet, with its technological and communicative power, has profoundly reshaped three performing arts: cinema, theater, and music. Through three emblematic case studies, the author delves into the intersection of digital media and artistic languages, illustrating how the medium affects both content and cultural engagement.

• Cinema: The study focuses on Eva.Stories, an innovative project leveraging Instagram Stories to narrate the historical memory of the Holocaust using a modern, youth-friendly language.

• Theater: The thesis discusses Innovating Colosseo, a distributed theatrical performance supported by advanced technologies like the GARR network and optical fiber, breaking the fourth wall and enabling interactivity.

• Music: It explores Spotify’s use of Artificial Intelligence to shape users’ musical preferences and create personalized listening experiences, thus opening new pathways for musical creativity.
Toward Identifying the QCD Critical Point: attenuation of the sound mode around the critical point

description: Motivated by the fact that QCD critical point (CP) belongs to the same universality class as the liquid-gas transition, the dynamical density fluctuations around the CP is analyzed using relativistic fluid dynamics for a viscous fluid. It is shown that relativistic effects on the dynamical structure factor of the density fluctuation appears only in the width of the sound and thermal modes through a modification of the transport/kinetic coefficients. It is found that the mechanical density fluctuation which is enhanced by the relativistic effects are attenuated, whereas the entropy fluctuation in turn becomes more prominent around the QCD CP. This attenuation of the density fluctuation around the QCD CP may imply that if the suppression or even total disappearance of Mach cone is observed as the incident energy of the relativistic heavy-ion collisionsis lowered, it can be a signal of the existence of the QCD critical point.

Publisher: name: INFN Open Access Repository
Year: 1994

description: In this paper we describe an application of the two component Dual Parton Model, for the simulation of high energy Cosmic Ray Cascades. The DPMJET interaction model has been tuned to accelerator data for hadron-nucleus and nucleus-nucleus interactions, and its performance in the fragmentation region has been optimized. We make use of this generator inside the HEMAS shower code. Results are presented with particular emphasis of the electromagnetic component and on the high energy muon content of the showers.

description: We discuss the implications of assuming a four-zero Yukawa texture for the charged Higgs decay $H^+ \to W^+ γ$ at one-loop level, within the context of the general 2-Higgs Doublet Model of Type III. We begin by presenting a detailed analysis of the charged Higgs boson couplings with heavy quarks and the resulting effects on its decays. In particular, we present the possible enhancement of the decay $H^+ \to W^+ γ$, whose branching ratio could be of the order $\sim 10^{-1}$, for charged Higgs mass of the order 180 GeV. These parameters can still avoid the $B \to X_s γ$ constraint and the perturbativity bound. The production of charged Higgs bosons is also sensitive to the modifications of its couplings, and we evaluate the events rates at the LHC, including the `direct' $c\bar{b}\to H^++c. c.$ and `indirect' $q\bar q, gg \to \bar t b H^++c. c.$ production channels. We get an event rate of order 60 (120) for `direct' (`indirect') production reaction, and including decay $H^+ \to W^+ γ$ in the final state, with an integrated luminosity of $10^5$ $pb^{-1}$.

description: We show that the strong hybridization between the iron 3d and the arsenic 4p orbitals, in the newly discovered iron-based high-T$_{c}$ superconductors, leads to an explanation of certain experimental observations that are presently not well understood. The existence of a lattice distortion, the smallness of the Fe magnetic moment in the undoped systems, and the suppression of both the lattice distortion and the magnetic order upon doping with fluorine, are all shown to result from this hybridization.

description: We consider the nonlinear algebras W(sl(4), sl(3)) and W(sl(3\\mid1),sl(3)) and find their realizations in terms of currents spanning conformal linearizing algebras. The specific structure of these algebras, allows us to construct realizations modulo null fields of the W3 algebra that lies in the cosets W(sl(4),sl(3))/u(1) and W(sl(3\\mid1),sl(3))/u(1). Such realizations exist for the following values of the W3 algebra central charge: cw =-30, -40/7, -98/5, -2. The first two values are listed for the first time, whereas for the remaining values we get the new realizations in terms of an arbitrary stress tensor and u(1) x sl(2) affine currents.
