description: The conditional quantum mutual information $I(A;B|C)$ of a tripartite state $ρ_{ABC}$ is an information quantity which lies at the center of many problems in quantum information theory. Three of its main properties are that it is non-negative for any tripartite state, that it decreases under local operations applied to systems $A$ and $B$, and that it obeys the duality relation $I(A;B|C)=I(A;B|D)$ for a four-party pure state on systems $ABCD$. The conditional mutual information also underlies the squashed entanglement, an entanglement measure that satisfies all of the axioms desired for an entanglement measure. As such, it has been an open question to find Rényi generalizations of the conditional mutual information, that would allow for a deeper understanding of the original quantity and find applications beyond the traditional memoryless setting of quantum information theory. The present paper addresses this question, by defining different $α$-Rényi generalizations $I_α(A;B|C)$ of the conditional mutual information, some of which we can prove converge to the conditional mutual information in the limit $α\rightarrow1$. Furthermore, we prove that many of these generalizations satisfy non-negativity, duality, and monotonicity with respect to local operations on one of the systems $A$ or $B$ (with it being left as an open question to prove that monotoniticity holds with respect to local operations on both systems). The quantities defined here should find applications in quantum information theory and perhaps even in other areas of physics, but we leave this for future work. We also state a conjecture regarding the monotonicity of the Rényi conditional mutual informations defined here with respect to the Rényi parameter $α$. We prove that this conjecture is true in some special cases and when $α$ is in a neighborhood of one.

description: Consider learning an imitation policy on the basis of demonstrated behavior from multiple environments, with an eye towards deployment in an unseen environment. Since the observable features from each setting may be different, directly learning individual policies as mappings from features to actions is prone to spurious correlations -- and may not generalize well. However, the expert's policy is often a function of a shared latent structure underlying those observable features that is invariant across settings. By leveraging data from multiple environments, we propose Invariant Causal Imitation Learning (ICIL), a novel technique in which we learn a feature representation that is invariant across domains, on the basis of which we learn an imitation policy that matches expert behavior. To cope with transition dynamics mismatch, ICIL learns a shared representation of causal features (for all training environments), that is disentangled from the specific representations of noise variables (for each of those environments). Moreover, to ensure that the learned policy matches the observation distribution of the expert's policy, ICIL estimates the energy of the expert's observations and uses a regularization term that minimizes the imitator policy's next state energy. Experimentally, we compare our methods against several benchmarks in control and healthcare tasks and show its effectiveness in learning imitation policies capable of generalizing to unseen environments.

description: The thesis deals with the remedy of the appeal with the purpose of studying it in the light of the guarantees of the defendant and the need to reduce the length of the trial. In this prospective, the firts chapter aims to find the ratio of the appeal by analyzing its historical evolution and its role in the context of other systems, of the international Charters and of the Italian Constitution. After demonstrating the defensive nature of the remedy, the second chapter shows how the most recent reforms have emphasised its characteristics of tool of protection of the defendant, paving the way to a rethinking of the appeal as a means available only to the accused person. Lastly, the third chapter focuses on the strategies to follow in order to contain the workload of the courts of appeal.

description: We analyze an entanglement-based quantum key distribution (QKD) architecture that uses a linear chain of quantum repeaters employing photon-pair sources, spectral-multiplexing, linear-optic Bell-state measurements, multi-mode quantum memories and classical-only error correction. Assuming perfect sources, we find an exact expression for the secret-key rate, and an analytical description of how errors propagate through the repeater chain, as a function of various loss and noise parameters of the devices. We show via an explicit analytical calculation, which separately addresses the effects of the principle non-idealities, that this scheme achieves a secret key rate that surpasses the TGW bound---a recently-found fundamental limit to the rate-vs.-loss scaling achievable by any QKD protocol over a direct optical link---thereby providing one of the first rigorous proofs of the efficacy of a repeater protocol. We explicitly calculate the end-to-end shared noisy quantum state generated by the repeater chain, which could be useful for analyzing the performance of other non-QKD quantum protocols that require establishing long-distance entanglement. We evaluate that shared state's fidelity and the achievable entanglement distillation rate, as a function of the number of repeater nodes, total range, and various loss and noise parameters of the system. We extend our theoretical analysis to encompass sources with non-zero two-pair-emission probability, using an efficient exact numerical evaluation of the quantum state propagation and measurements. We expect our results to spur formal rate-loss analysis of other repeater protocols, and also to provide useful abstractions to seed analyses of quantum networks of complex topologies.

Bias Correction of Persistence Measures in Fractionally Integrated Models

description: This paper investigates the accuracy of bootstrap-based bias correction of persistence measures for long memory fractionally integrated processes. The bootstrap method is based on the semi-parametric sieve approach, with the dynamics in the long memory process captured by an autoregressive approximation. With a view to improving accuracy, the sieve method is also applied to data pre-filtered by a semi-parametric estimate of the long memory parameter. Both versions of the bootstrap technique are used to estimate the finite sample distributions of the sample autocorrelation coefficients and the impulse response coefficients and, in turn, to bias-adjust these statistics. The accuracy of the resultant estimators in the case of the autocorrelation coefficients is also compared with that yielded by analytical bias adjustment methods when available. The basic sieve technique is seen to yield a reduction in the bias of both persistence measures. The pre-filtered sieve produces a substantial further reduction in the bias of the estimated impulse response function, whilst the extra improvement yielded by pre-filtering in the case of the sample autocorrelation function is shown to depend heavily on the accuracy of the pre-filter.

Design, development, and validation of innovative motor telerehabilitation systems
Creators: name: ZEDDA, ANDREA
Publisher: name: Universit� degli studi di Genova
Year: 2021

description: Telerehabilitation is a branch of telemedicine that aims to rehabilitate the patient from remote, with the help of ICT solutions. By bringing the rehabilitation tools to the patients? home, providing ways to control their progress and correct their errors, telerehabilitation systems promote fair access to the treatments also for those patients who live far from the rehabilitation centers or present limited autonomy in reaching them. As telerehabilitation limits the real-time interaction with the rehabilitation staff and the exercises are usually repetitive and boring, the main risk is the reduction of the compliance to the prescribed protocol. In long-term rehabilitation situations, this often leads to dropouts, thus limiting the recovery. To avoid such problems, an interesting development is the use of playful tools, such as video games, for rehabilitation purposes. These tools are called exergames because they help the patient to exercise in a gamified scenario. Although exergame-based rehabilitation systems are moving from the research to the market, the combined use of low-cost platforms, telerehabilitation based on quantitative measurements of biomechanical parameters, and exergames is still seen as the holy grail in the field. This is due to the complexity of these systems, which limits the adoption of low-end computing platforms, and to the quality of the sensor-based movement analysis, which is usually inadequate for telemonitoring purposes. Moreover, commercial solutions developed for this aim reveal severe limitations in the functionality and are closed systems with limited, when even possible, extendibility. Costs and accessibility for patients with low computer literacy are further problems that are seldom addressed. This thesis presents the design, development, and technological validation of a telerehabilitation system for stroke survivors with mild motor impairment, based on low-cost, wearable, and portable technologies. Such a system was developed in the context of the DoMoMEA project. Collaterally, beyond-state-of-the-art solutions were studied and here presented to innovate in the field of technologies for rehabilitation. In particular, advanced manipulation of the visual feedback in exergames was explored, to mimic, in exercises against gravity only, some effects achievable with haptic robots. Moreover, the validation of technologies for the development of smart clothing for telerehabilitation was pursued, with particular emphasis on the possibility to detect surface EMG signals during rehabilitation exercises. Such technologies could be easily integrated in the developed telerehabilitation platform for advanced studies. Preliminary validations, hampered by the COVID-19 pandemic in the last year, were obtained on healthy people.
Torsion in big mapping class groups
Creators: name: Huynh, Andy
Publisher: name: No Publisher Supplied
Year: 2022

description: The mapping class group of a surface has been well studied, particularly for compact surfaces and allowing for permutations of finitely many marked points. Many of these results though do not automatically extend for non-compact surfaces, particularly for infinite-type surfaces. A surface is of finite-type if its fundamental group is finitely generated, and it is of infinite-type if its fundamental group cannot be finitely generated. While work has been done by many authors to show that mapping class groups of finite-type surfaces are generated by torsion elements, not much has been done for the infinite-type case. We extend torsion generation of mapping class groups for finite-type surfaces to mapping class groups for specific infinite-type surfaces. We show that for the cases of infinite-type surfaces that we work on, their mapping class groups are topologically generated by involutions. In some cases, we are able to get the topological generating set to be a finite set, which we can view as a version of finite generation of such mapping class groups.

A reluctant additive model framework for interpretable nonlinear individualized treatment rules

description: Individualized treatment rules (ITRs) for treatment recommendation is an important topic for precision medicine as not all beneficial treatments work well for all individuals. Interpretability is a desirable property of ITRs, as it helps practitioners make sense of treatment decisions, yet there is a need for ITRs to be flexible to effectively model complex biomedical data for treatment decision making. Many ITR approaches either focus on linear ITRs, which may perform poorly when true optimal ITRs are nonlinear, or black-box nonlinear ITRs, which may be hard to interpret and can be overly complex. This dilemma indicates a tension between interpretability and accuracy of treatment decisions. Here we propose an additive model-based nonlinear ITR learning method that balances interpretability and flexibility of the ITR. Our approach aims to strike this balance by allowing both linear and nonlinear terms of the covariates in the final ITR. Our approach is parsimonious in that the nonlinear term is included in the final ITR only when it substantially improves the ITR performance. To prevent overfitting, we combine cross-fitting and a specialized information criterion for model selection. Through extensive simulations, we show that our methods are data-adaptive to the degree of nonlinearity and can favorably balance ITR interpretability and flexibility. We further demonstrate the robust performance of our methods with an application to a cancer drug sensitive study.

description: We use an exact solution of the elastic membrane shape equation, representing the curvature, which will serve as a quantum potential in the quantum mechanical two dimensional Schrodinger equation for a (quasi-) particle on the surface of the membrane. Surface curvature in the quasi one-dimensional case is related to an unexpected static formation: on one hand the elastic energy has a maximum where surface curvature has a maximum and on the other hand the concentration of the expectation value to find the (quasi-) particle is again where the elastic energy is concentrated, namely where surface curvature has a maximum. This represents a particular form of a conformon.
Towards a DNA-based biosensor: a multi-technique study for sequence recognition
Creators: name: PINTO, GIULIA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The challenge to defeat diseases starting from a rapid diagnosis has been relighted by the last pandemic due to SARS-CoV-2. The development of biosensors able to recognize molecular adsorption on surfaces plays a crucial role in this issue, allowing for example to detect the presence of disease biomarkers, like specific nucleic acid sequences or antibodies, in solution. Currently, viral RNA detection relies almost exclusively on polymerase chain reaction (PCR), requiring an expensive and complex process, or on fluorescent methods using labels that could interfere with the hybridization process. We exploited spectroscopic ellipsometry (SE) label-free experiments to detect UV-Vis molecular absorptions at the monolayer level in order to develop biosensing platforms. Spectroscopic ellipsometry is a non-perturbative and extremely sensitive method for the analysis of ultrathin molecular films. Changes in polarization of a light beam upon reflection from the sample surface are detected, providing information, both quantitative and molecular-specific, on film thickness and optical properties. In fact, SE difference spectra, obtained as the difference between the spectra acquired after the molecular deposition and the spectra acquired on the bare substrate, clearly show molecular absorption fingerprints in the UV-Vis-NIR spectral range. We focus on an optical DNA-based biosensor, where DNA strands immobilized on gold can detect specific SARS-CoV-2-related RNA sequences through nucleic acid hybridization. DNA-based biosensors are an excellent option to develop micro-nano devices which are reusable thanks to the denaturation property of nucleic acids. DNA self-assembled monolayers are studied in situ and in real time through a multi-technique approach, in order to optimize the experimental protocol and design the cheaper and more efficient biosensor. The tuning of several parameters, like ssDNA immobilization time, concentration of molecular spacer solution and solution ionic strength, allowed us to highlight the subtle interplay of these factors in the DNA self-assembly process. Upon hybridization, changes in film thickness (AFM nanolithography, SE), molecular UV-Vis absorption (SE), coverage (XPS, QCM-D) are detected. In particular, SE allows to recognize the double-helix formation in situ, in a non-destructive and extremely fast way, and to detect DNA hypochromism at the monolayer level, for the first time to our knowledge. In conclusion, an accurate optical SE model, supported by AFM thickness data, allowed us to optically characterize ssDNA and dsDNA films in the whole probed wavelength region, providing a new tool for nucleic acid sequence recognition.

description: We introduce left and right-layered trees as trees with a specific representation and define the excess of a tree. Applying these ideas, we show a range-relaxed graceful labeling which improves on the upper bound for maximum vertex label given by Van Bussel. For the case when the tree is a lobster of size $m$ and diameter $d$, the labeling produces vertex labels no greater than $\frac{3}{2}m-\frac{1}{2}d$. Furthermore, we show that any lobster $T$ with $m$ edges and diameter $d$ has an edge-relaxed graceful bipartite labeling with at least $\max\{\frac{3m-d+6}{4},\frac{5m+d+15}{8}\}$ of the edge weights distinct, which is an improvement on a bound given by Rosa and Širáň on the $α$-size of trees, for $d\frac{5m-65}{7}$. We also show that there exists an edge-relaxed graceful labeling (not necessarily bipartite) with at least $\max\left\{\frac{3}{4}m+\frac{d-ν}{8}+\frac{3}{2},ν\right\}$ of the edge weights distinct, where $ν$ is twice the size of a partial matching of $T$. This is an improvement on the gracesize bound of Rosa and Širáň for certain values of $ν$ and $d$. We view these results as a step towards Bermond's conjecture.

description: A quantization procedure, which has recently been introduced for the analysis of Painlevé equations, is applied to a general time-independent potential of a Newton equation. This analysis shows that the quantization procedure preserves the exact solvability property for the class of shape-invariant potentials. When a general potential is considered the quantization procedure involves the solution of a Gambier XXVII transcendental equation. Explicit examples involving classical and exceptional orthogonal Laguerre and Jacobi polynomials are discussed.

description: According to a recent Census report, since the Affordable Care Act (ACA) was passed in 2010, the rate of individuals without health insurance in the United States increased two years in a row in 2018 and 2019. If the Affordable Care Act was designed to ensure that all Americans had health insurance, why and how is the policy failing to serve that purpose? Healthcare in the Netherlands, by contrast, is provided through a structure similar to the ACA, and yet such problems of declining coverage have not occurred. A unitary parliamentary structure and a corporatist tradition of relationships between the Dutch government and interest groups allowed policymakers to design a healthcare reform with fewer moving parts that better fit together. My dissertation examines three questions. First, how do institutional differences between the United States and the Netherlands generate differing feedback effects in the two countries? Second, how does partisan polarization affect the mobilization of interest groups and the perceptions of healthcare policy makers and stakeholders? Three, how do ACA-exempt plans affect benchmark premiums in ACA exchanges? My dissertation focuses on STLDIs as the main vehicles by which the Trump administration undercut the usefulness of the ACA. Understanding policy feedback effects in healthcare policymaking reveals mechanisms that determine why some policies are sustainable and durable while others fail. On the question of sustainability of the ACA, policy feedback frameworks provide useful tools. It is clear that the ACA has been undermined by such negative feedback effects as high deductibles in the ACA-compliant plans. The Trump administration used ACA-exempt plans in part to expand access to health insurance, since ACA-compliant plans are unaffordable to many Americans who are just above the 400% federal poverty level. In doing so, it ignored the issue of access to healthcare services since ACA-exempt plans do not have to provide essential benefits. Democrat-controlled states took various measures such as complete ban in some states, limitation on their duration, ban on online sales to protect consumers from ACA-exempt plans. Hospitals and the insurance industry were largely opposed to Trump administration efforts to make STLDIs widely available because they foresaw fragmentation and destabilization of insurance markets and a rise of unpaid hospital bills. On February 15, 2021, newly elected President Biden signed an executive order instructing federal agencies to reverse the Trump’s administration rules on the ACA-exempt plans. My research addresses the question of healthcare policies’ sustainability by arguing that the institutional characteristics of the U.S. political system make it painfully difficult to design a reform that is sustainable. Among many obstacles are low trust in government among many Americans and the abundance of veto points in the policymaking process.

description: Semiconductor heterostructures provide a powerful platform for the engineering of excitons. Here we report the excitonic properties of two-dimensional (2D) heterostructures that consist of monolayer MoS2 and WS2 stacked epitaxially or non-epitaxially in the vertical direction. We find similarly efficient interlayer relaxation and transition of excitons in both the epitaxial and nonepitaxial heterostructures. This is manifested by a two orders of magnitude decrease in the photoluminescence and the appearance of an extra absorption peak at low energy region. The MoS2/WS2 heterostructures show weak interlayer coupling and can essentially act as atomicscale heterojunctions with the intrinsic bandstructures of the two monolayers largely preserved. They are particularly promising for the applications that request efficient dissociation of excitons and strong light absorption, including photovoltaics, solar fuels, photodetectors, and optical modulators. Our results also indicate that 2D heterostructures promise unprecedented capabilities to engineer excitons from the atomic level without concerns of interfacial imperfection.

description: Η μετάβαση στην μετά-Covid εποχή χαρακτηρίζεται από τεχνολογικές εξελίξεις οι οποίες απασχολούν όλους τους κλάδους της Οικονομίας της Χώρας. Ο ψηφιακός μετασχηματισμός αποτελεί μια από τις βασικές προτεραιότητες της ΕΕ, δημιουργώντας νέες ευκαιρίες για επιχειρήσεις και οργανισμούς, και συμβάλλοντας στην βελτιστοποίηση διαδικασιών. Ένας κλάδος ο οποίος χαρακτηρίζεται από ταχύρρυθμες αλλαγές είναι ο αθλητικός κλάδος, με αναδυόμενες ευκαιρίες ανάπτυξης, και χρήζει ψηφιακού μετασχηματισμού. Συνοπτικά, μερικοί από τους τομείς ψηφιακής ανάπτυξης ενός αθλητικού οργανισμού ή μιας αθλητικής εγκατάστασης σχετίζεται με την διεύρυνση των μέσων που επικοινωνεί με το κοινό-«πελάτες» του, την ψηφιοποίηση των χορηγικών δράσεων, του υλικού που μπορεί να κατέχει και να επενδύσει στην ψηφιακή μετάβαση. Για να επιτευχθούν τα ανωτέρω παραδείγματα, απαιτείται η αναβάθμιση των παραδοσιακών διαδικασιών και εργασιών με εκπαίδευση και υποστήριξη όλων των εμπλεκόμενων (εργαζόμενοι, αθλητές, προπονητές, γονείς, προμηθευτές, κλπ.). Συνεπώς στην παρούσα διπλωματική εργασία εξετάζεται η ψηφιακή ωριμότητα οργανισμών για τον ψηφιακό μετασχηματισμό, και η ετοιμότητά τους με το ξέσπασμα της πανδημίας αναλύοντας τα βήματα και τις διαδικασίες ψηφιακού μετασχηματισμού. Συγκριτικά με την Ευρώπη, η Ελλάδα βρίσκεται σε χαμηλή θέση σχετικά με τις ψηφιακές δεξιότητες. Παράλληλα, αναλύονται οι ενέργειες ψηφιακού μετασχηματισμού στην Ελλάδα την εποχή του Covid-19, και πιο συγκεκριμένα στον αθλητικό χώρο, με τις προκλήσεις και τα οφέλη που δημιουργούνται. Επίσης, παρουσιάζονται οι μελέτες περιπτώσεων αθλητικών οργανισμών και εγκαταστάσεων στην εποχή του Ψηφιακού Μετασχηματισμού, και οι επιχειρηματικές στρατηγικές, στη νέα εποχή της ψηφιοποίησης.
Consuming the centerfold: sexuality and the fantasy of the American good life

Publisher: name: No Publisher Supplied
Year: 2022

description: “Consuming the Centerfold” is a cultural history that forefronts the perspectives and agency of sexually marginalized groups as they navigated the rapid cultural changes transpiring in the second half of the twentieth century. This dissertation analyses five sexually provocative magazines made by and for those other than heterosexual white men. Duke (1957), Drum (1964-1969), Playgirl (1973-1977), MsTique (1974-1976), and On Our Backs (1984-1994) each worked to construct newly visible and distinctive sexual identities for their respective audiences of Black men, gay men, white women, Black women, and lesbians. “Consuming the Centerfold” argues that the consumption of sexual imagery was a critical tool for marginalized groups seeking to construct new ideas of sexual and economic freedom. For those whose expressions of sexuality had long been politically oppressed and culturally stigmatized, the production and consumption of their own sexual imagery was not just an egalitarian gesture, but an unprecedented opportunity to publicly assert their right to the privileges of sexual citizenship. Duke, Drum, Playgirl, MsTique, and On Our Backs sanctioned their readers’ active explorations of pleasure, passion, and desire, and fought for their right to do so without shame, fear, or punishment. At different times and in different ways, these highly inventive and highly experimental magazines offered their readers an intimate, autonomous space to construct and claim control over their own modern sexual identities. These pioneers of sexual citizenship insisted that Black men, gay men, white women, Black women, and lesbians envision themselves as empowered sexual agents in rightful possession of a healthy erotic gaze. And by strategically appropriating elements of consumerism and sexual liberalism, they sought to extend the pleasures of fantasy and desire to those often denied. Examined in tandem, these five magazines help to reveal the intricate meanings, strategies, and contradictions that emerged for sexually marginalized people as consumerism and sexual expression became increasingly key privileges of American citizenship. Duke, Drum, Playgirl, MsTique, and On Our Backs each created their own public sexual discourse, and in the process, constructed compelling visions—or fantasies—of what it means to be a full participant in American society.

description: In this paper we investigate quasi-Monte Carlo (QMC) integration using digital nets over $\mathbb{Z}_b$ in reproducing kernel Hilbert spaces. The tent transformation, or the baker's transformation, was originally used for lattice rules by Hickernell (2002) to achieve higher order convergence of the integration error for smooth non-periodic integrands, and later, has been successfully applied to digital nets over $\mathbb{Z}_2$ by Cristea et al. (2007) and Goda (2014). The aim of this paper is to generalize the latter two results to digital nets over $\mathbb{Z}_b$ for an arbitrary prime $b$. For this purpose, we introduce the {\em $b$-adic tent transformation} for an arbitrary positive integer $b$ greater than 1, which is a generalization of the original (dyadic) tent transformation. Further, again for an arbitrary positive integer $b$ greater than 1, we analyze the mean square worst-case error of QMC rules using digital nets over $\mathbb{Z}_b$ which are randomly digitally shifted and then folded using the $b$-adic tent transformation in reproducing kernel Hilbert spaces. Using this result, for a prime $b$, we prove the existence of good higher order polynomial lattice rules over $\mathbb{Z}_b$ among the smaller number of candidates as compared to the result by Dick and Pillichshammer (2007), which achieve almost the optimal convergence rate of the mean square worst-case error in unanchored Sobolev spaces of smoothness of arbitrary high order.

description: Το ξέσπασμα του SARS-COV-2 οδήγησε στην πανδημία COVID-19 τον Μάρτιο του 2020 και προκάλεσε πάνω από 4,5 εκατομμύρια θανάτους παγκοσμίως έως τον Σεπτέμβριο του 2021. Εκτός από την κρίση της δημόσιας υγείας, ο COVID-19 επηρέασε σημαντικά την παγκόσμια οικονομία και ανάπτυξη, με ιδιαίτερη επίδραση στους τομείς της ενέργειας, της ναυτιλίας, των μεταφορών αλλά και της φαρμακοβιομηχανίας. Η αναγνώριση των δυσμενών επιπτώσεων της πανδημίας COVID-19 είναι ζωτικής σημασίας για τον μετριασμό των αρνητικών αλλαγών συμπεριφοράς που σχετίζονται άμεσα με την ψυχολογική και κοινωνική ευημερία των ανθρώπων. Οι κύριες πηγές επιπτώσεων στους τομείς της ενέργειας, της ναυτιλίας, των μεταφορών αλλά και της φαρμακοβιομηχανίας αποτέλεσαν το αντικείμενο διερεύνησης της παρούσας εργασίας. Μεθοδολογικά ακολουθήθηκε η μέθοδος της βιβλιογραφικής ανασκόπησης με αναζήτησε σε πηγές διαδικτύου όπως το google scholar, pubmed , scopus με τη χρήση βοήθειας λέξεων κλειδιών όπως πανδημία, covid19, μεταφορές, ναυτιλία, ενέργεια. Από τα αποτελέσματα της έρευνας φάνηκε ότι η πανδημία είχε ως συνέπεια την πρόκληση αρκετών αρνητικών συνεπειών σε πολλούς τομείς της κοινωνικής και οικονομικής ζωής, με χαρακτηριστικούς τομείς αυτόν της ενέργειας, της βιομηχανίας τροφίμων, της ναυτιλίας, της οικονομίας καθώς επίσης και της φαρμακοβιομηχανίας και της υγείας γενικότερα. Οι μεταφορές τροφίμων και πρώτων υλών περιορίστηκαν, πολλά λιμάνια έκλεισαν και τα πλοία μετατράπηκαν απλώς σε αποθήκες τροφίμων. Περαιτέρω, αξίζει να σημειωθεί ότι στον τομέα της ενέργειας οι τιμές του αργού πετρελαίου γνώρισαν διακυμάνσεις είτε προς τα πάνω είτε προς τα κάτω με συνέπεια να επέλθουν περαιτέρω δυσμενείς επιπτώσεις τόσο στους ναύλους των πλοίων για τη μεταφορά τους όσο και στις οικονομίες των αναπτυσσόμενων και πολιτικά ασταθών οικονομιών, οι οποίες δεν μπορούσαν να ανταπεξέλθουν στη δίνη της πανδημίας. Τέλος, στον τομέα της φαρμακοβιομηχανίας παρατηρήθηκαν ελλείψεις σε φάρμακα ασθενών με χρόνιες παθήσεις, αυξήσεις στις τιμές φαρμακευτικών προϊόντων εν γένει λόγω κυρίως της αύξησης των τιμών παραγωγής των φαρμάκων και των φαρμακευτικών σκευασμάτων, ενώ δαπανήθηκαν πολλά εκατομμύρια ευρώ στον τομέα αυτό προκειμένου οι φαρμακοβιομηχανίες να μπορέσουν να κατασκευάσουν φάρμακα και εμβόλια κατά της πανδημίας.
The Kingdom of Saudi Arabia's Kafala System concerning Migrant Domestic Workers and its Impact on the Fight against Human Trafficking

description: The relationship between migrant workers and their employers is determined within the framework of the Saudi provisions of Kafala, under which the employer gains wide prerogative over the worker. This has resulted in some employers arbitrarily misusing these broad powers, depriving the worker of travelling to his or her country of origin even in emergency circumstances and forcing the worker to perform work other than that stipulated in the employment contract. In addition, according to the Kafala system, the worker must seek the permission of the employer when he or she wishes to work elsewhere. Also, the employer can report the worker as a runaway if he or she acts without their permission which therefore makes the worker more susceptible to being deported or imprisoned.
