The Racial Myth of the Black Violence: A Žižekian Study of Toni Morrison's The Bluest Eye, Sula, and Beloved
Publisher: name: University of kurdistan
Year: 2023

description: The bulk of what we know as violence is myth. Since myths have been told and retold over the years, they have been taken as truth. This paper explores racial myths as representations of verbal violence in Toni Morrison's The Bluest Eye, Sula, and Beloved. Toni Morrison as an African-American identity explorer dwells on the slogans and myths as manifestations of Žižekian symbolic violence. Methodologically, this study uses political discourse analysis, black gendered feminism and psychoanalysis in the light of Slavoj Žižek's commentary on violence to be the approaches of analyzing the drawn data. The fusion of psychoanalytic terms with political ones sheds a fresh light on the concepts of ideology and violence. This paper aims at exploring the mechanisms of the black violence myth that spread the racial beliefs that Africans are more violence prone and have higher pain tolerance than Europeans. The conclusion extracted from this study confirms that the discourse of the myths functions as pseudo-ideologies to normalize the violence against non-European races and stop the African subalterns' resistance in the form of fighting back against the raids of the Europeans.

description: In the upcoming sixth-generation (6G) era, the demand for constructing a wide-area time-sensitive Internet of Things (IoT) keeps increasing. As conventional cellular technologies are hard to be directly used for wide-area time-sensitive IoT, it is beneficial to use non-terrestrial infrastructures including satellites and unmanned aerial vehicles (UAVs), where a non-terrestrial network (NTN) can be built under the cell-free architecture. Driven by the time-sensitive requirements and uneven distribution of IoT devices, the NTN is required to be empowered by mobile edge computing (MEC) while providing oasis-oriented on-demand coverage for the devices. Nevertheless, communication and MEC systems are coupled with each other under the influence of complex propagation environment in the MEC-empowered NTN, which makes it hard to orchestrate the resources. In this paper, we propose a process-oriented framework to design the communication and MEC systems in a time-division manner. Under this framework, the large-scale channel state information (CSI) is used to characterize the complex propagation environment with an affordable cost, where a non-convex latency minimization problem is formulated. After that, the approximated problem is given and it can be decomposed into subproblems. These subproblems are further solved in an iterative way. Simulation results demonstrate the superiority of the proposed process-oriented scheme over other algorithms. These results also indicate that the payload deployments of UAVs should be appropriately predesigned to improve the efficiency of resource use. Furthermore, the results imply that it is advantageous to integrate NTN with MEC for wide-area time-sensitive IoT.

description: The masses of $1^{--}$ charmonium and bottomonium hybrids are evaluated in terms of QCD sum rules. We find that the ground state hybrid in charm sector lies in $m_{H_c}=4.12\sim 4.79$ GeV, while in bottom sector the hybrid may situated in $m_{H_b} = 10.24\sim 11.15$ GeV. Since the numerical result on charmonium hybrid mass is not compatible with the charmonium spectra, including structures newly observed in experiment, we tempt to conclude that such a hybrid does not purely exist, but rather as an admixture with other states, like glueball and regular quarkonium, in experimental observation. However, our result on bottomonium hybrid coincide with the "exotic structure" recently observed at BELLE.

description: Material surface - analyte interactions play important roles in numerous processes including gas sensing. However, the effects of topological polar surface area (TPSA) of analytes on surface interactions during gas sensing have been so far largely disregarded. In this work, based on experimental observations on changes in electrical resistance of cadmium sulphide (CdS) due to surface interactions during gas sensing, we found that unexpected univariate quadratic correlation exists between changes in resistance of CdS and TPSA of analytes. Further experiments on four other material systems showed the same trend, revealing a generalized picture of TPSA dependence of surface interactions.

Tess’s Language and Her Victimization: Speech Act Theory in Tess of the d'Urbervilles
Publisher: name: University of kurdistan
Year: 2023

description: The present study aims to investigate speech acts in Thomas Hardy’s Tess of the d'Urbervilles based on John Austin’s theory. In the present research, the researcher attempts to investigate female characters’ speech acts in the selected novel at three levels of locutionary act, illocutionary act, perlocutionary act. Austin theories have been published in the book titled How to Do Things with Words which introduces speech acts. The philosophers believes that language is used to display the world. In other words, it shows what exists and what does not exist. The same mechanism can be traced and studied in Tess’s speech acts. It might be claimed that for Tess, the language is not the means of transferring meanings. It is a tool through which their psyche, identity, and the course of their life can be constructed. Using linguistic theories in analyzing the selected work can both depict new aspects of the novel and give insights to the linguists. It can be concluded that the speech acts are the reason why Tess fails in the society and have tragic destiny and the link between the characters’ language and psyche would be detected.
Characterization of genomic alterations in CIITA and their functional and clinical implications in malignant lymphomas
Creators: name: Mottok, Anja
Publisher: name: University of British Columbia
Year: 2017

description: Emerging evidence that the interplay between tumour cells and reactive immune cells has profound impact on tumour development, evolution and progression inspired the field of cancer research for the last decade. It has become apparent that the evolutionary pressure exerted by the immune system leads to the evolution of various mechanisms by which tumour cells escape immune surveillance. These often include somatically acquired genetic alterations, resulting in disturbed expression of surface molecules or an altered chemokine/cytokine milieu. B cells play an important role in the adaptive immune response and are potent antigen-presenting cells with high expression of major histocompatibility complexes (MHC) I and II. Multiple studies have reported on defective antigen presentation pathways in malignant lymphomas, however, many of the underlying genetic alterations are largely unexplored. Herein, we applied next generation sequencing techniques and fluorescence in situ hybridization to explore the landscape of genetic alterations in CIITA, the master transcriptional regulator of MHC class II, in various B cell lymphomas and to determine the spectrum of rearrangement partner genes. The functional impact of these mutations on MHC class II expression and the composition of the tumour microenvironment were subsequently evaluated in cell line model systems, and by immunohistochemistry performed on primary lymphoma specimens. Finally, we integrated our findings with patient outcomes to ascertain the clinical impact. We discovered that genomic rearrangements and coding sequence mutations in CIITA are frequent across B cell lymphoma subtypes and can result in diminished MHC class II expression, coinciding with a lower abundance of CD4- and CD8-positive T cells in the tumour microenvironment. We identified that at least some of the genetic alterations are likely a byproduct of AID-mediated somatic hypermutation, as evidenced by the co-occurrence of mutations in the non-coding region of CIITA intron 1. In addition, we described novel translocations involving a broad spectrum of rearrangement partner genes and intra-chromosomal structural variants. In summary, we established CIITA genetic alterations as a frequent immune escape strategy exploited by a variety of malignant B cell lymphomas. These mutations resulted in reduced MHC class II expression and altered microenvironment composition.

description: A superconducting quantum magnetometer based on magnetic flux-driven modulation of the density of states of a proximized metallic nanowire is theoretically analyzed. With optimized geometrical and material parameters transfer functions up to a few mV/Phi_0 and intrinsic flux noise ~10^{-9}Phi_0 Hz^{-1/2} below 1 K are achievable. The opportunity to access single-spin detection joined with limited dissipation (of the order of ~ 10^{-14} W) make this magnetometer interesting for the investigation of the switching dynamics of molecules or individual magnetic nanoparticles.

description: Estimator algorithms in learning automata are useful tools for adaptive, real-time optimization in computer science and engineering applications. This paper investigates theoretical convergence properties for a special case of estimator algorithms: the pursuit learning algorithm. In this note, we identify and fill a gap in existing proofs of probabilistic convergence for pursuit learning. It is tradition to take the pursuit learning tuning parameter to be fixed in practical applications, but our proof sheds light on the importance of a vanishing sequence of tuning parameters in a theoretical convergence analysis.
Le tracce di un passato ancestrale: mito e storia in Pier Paolo Pasolini
Creators: name: BIANCHI, MATTEO
Publisher: name: Universit� degli studi di Bergamo
Year: 2017

description: In a context of comparative theory this essay focuses on the myth of childhood in Pier Paolo Pasolini?s work. By analyzing his Friulan period in some of his films and several dreams, it can be noticed how some recurrent symbols of his work, realize that desire of retrogradation backward to barbarism, represented by his mother through a psychoanalytical perspective.
The aim of the present dissertation is to present how Friuli is a constant presence in all Pasolini?s activity. For this persistence the poet shows a great interest in the past and in the otherness, embodied by the boys of Casarsa, the lowest among the roman classes and the poorest from the Third World. In this way Pasolini appears to the reader in all its phenomenological complexity, that only in virtue of the �concrete imagination� it can be made more clear.

description: We present arguments aiming at reconciling apparently contradictory results concerning the chemical composition of cosmic rays of highest energy, coming recently from the Auger and HiRes collaborations. In particular, we argue that the energy dependence of the mean value and root mean square fluctuation of shower maxima distributions observed by the Auger experiment are not necessarily caused by the change of nuclear composition of primary cosmic rays. They could also be caused by the change of distribution of the first interaction point in the cascade. A new observable, in which this influence is strongly suppressed, is proposed and tested.

Personality Traits and Translation: The Effect of Introvert and Extrovert Personality Types on Translation Quality of Political and Journalistic Texts
Publisher: name: University of kurdistan
Year: 2023

description: The current study is interdisciplinary research having a psychological look at the quality of translated texts. This work was an endeavor to probe the effect of the translators' personality- extrovert and introvert- on the translation quality of political and journalistic texts. It also explored the effect of the graduation level on the translation quality. To achieve the ends, the data was obtained from 50 graduate and 50 undergraduate students majoring in English translation at different Iranian universities. The translated texts were assessed by three ratters using Farahzad’s model (1992) of translation quality assessment. The results of independent samples t-test revealed that the personality characteristics of the participants did not have significant effect on the translation quality. Moreover, the results of ANOVA indicated that the extrovert students had a better performance than the introverts in the accuracy scale, but the reverse pattern emerged in the case of style scale where the introverts outperformed the extroverts. The research has attempted to consider the interrelationship between psychology and translation field and can be beneficial for importing concepts and theories from the field of psychology. Regarding the results, "introversion" and "extroversion" can be considered as two sources of variation in translation process and outcome.

Il volume � suddiviso in tre parti. Nella prima vengono presentate le pionieristiche teorie del capitale umano elaborate negli anni ?60 del secolo scorso dai tre famosi economisti dell?Universit� di Chicago, T.W. Schultz, J. Mincer e G.S. Becker, quindi viene analizzato il tasso di rendimento, quale metodo per valutare la redditivit� dell?investimento educativo. Nella seconda si approfondisce il legame tra istruzione e crescita economica, con un?attenzione particolare al tema della qualit� della scuola, caro a E.A Hanushek., per finire con le pi� promettenti ultime linee di ricerca di economia dell?istruzione offerte dai contributi di Dagum e Heckman. L?ultima parte, infine, approfondisce il rapporto economia e pedagogia. L?approccio storico-strutturale permette di evidenziare il cambiamento che il rapporto subisce nel tempo nella direzione di una progressiva autonomia dell?educazione dall?economia. In questo processo le teorie del capitale umano hanno avuto un ruolo rilevante. Il volume non si prefigge di offrire ricette definite ma aspira a porsi come strumento di riflessione in un ambito di ricerca che � stato finora largamente trascurato negli studi pedagogia.

We use a conventional mass spectrometer to identify the krypton content of the xenon, but we improve the sensitivity of the device by about five orders of magnitude with a liquid nitrogen cold trap. We find that the absolute krypton concentration of the xenon can be inferred from the mass spectrometry measurements, and we identify krypton signals at concentrations as low as 0.5x10^{-12} mol/mol (Kr/Xe). This technique simplifies the monitoring of krypton backgrounds for WIMP dark matter searches in liquid xenon.

The Effect of Reading and Teaching Literary Texts on the Vocabulary Range and Composition Length Development: A Case Study of Intermediate EFL Learners
Publisher: name: University of kurdistan
Year: 2023

description: The effect of reading and teaching literary texts on the development of productive skills of language learners has long been an eye-catching factor for researchers. Having determined the interest through analysis, the present study seeks to search the effect of literary texts on the enhancement of vocabulary usage and composition length of the EFL learners. To achieve the above-mentioned desire, a case study was designed, including the population of 15 intermediate EFL. The case was chosen from the language learners of the Velayat University of Iranshahr. They were supposed to read and discuss a literary text, the effect of which on their writing was later compared to a previously prepared composition, before the exposure of the literary text. A focus on the vocabulary range and composition length along with the progression of their ideas in writing revealed that literary text and the discussion session were highly influential on the above-mentioned features. They used more lexical resources from the literary text in their composition along with a longer and more comprehensive text in terms of progression.
Macroeconomic impacts of the global financial crisis on the Bangladesh economy

Year: 2010

description: This paper examined the impacts of the current 2007-09 global crisis on the macro-economy of Bangladesh. The evidence suggests that the impact of the crisis had been rather mild with modest slowdown of the economy and a few critical sectors (exports and remittances), but at the same time, the adverse effects being offset by improvements in some other sectors (agriculture and equity markets), thus showing remarkable resilience to the crisis. Further, the impact on Bangladesh was much milder than those felt in both developed countries (such as the U.S. and EU countries) and other emerging economies such as India and China. Appropriate and timely policy actions at the global level along with the country?s own fiscal and monetary policy stimulus were helpful in achieving these results. Additional factors that helped minimize the adverse impacts include the country?s relative non-exposure to the overseas toxic assets, growth of the agricultural sector, and resilience of garment exports and worker remittance sectors. A SWOT analysis of the country indicates that, as the global economy turns around, the country could take advantage of many global opportunities provided the country can capitalize on its strengths, improve upon its weaknesses and deal effectively with emerging threats. Policy actions that may be helpful include strengthening internal and external sector reforms, infrastructure development, export diversification, finding new markets for exports and worker employment abroad, and leveraging benefits from cooperation and partnerships with foreign businesses including overseas Bangladeshi expatriates, among others.
Implicit ELT Policies Embedded in the Professional Practices of Selected Private Language Publishers and Institutes in Iran
Publisher: name: University of kurdistan
Year: 2023

description: English language teaching policies have recently become a growing concern in several countries, including Iran. Whereas several studies have noted the role of explicit policy documents and texts, fewer studies have explored the role of implicit ELT policies. This research investigates the implicit ELT policies embedded in professional practices of selected private English language publishers and institutes in Iran. The study’s qualitative data comprised documents and archival information taken from sources such as official websites, social networking accounts, catalogs, and brochures of eight prominent publishers and eight leading English language institutes. Thematic analysis of the data revealed three aspects of the publishers' activities (Nominal features, Supplementary materials, and Practical features) and four main aspects of professional practices of the language institutes (Overcategorizations, Tests, Teachers, and Coursebooks). The findings suggest that the practices of the leading publishers and institutes might act as implicit policies which would most likely provide directions for other publishers and institutes in the country to pursue and adopt. Thereby, it is suggested that instead of following pre-set accepted agendas, the leading publishers and institutes work creatively to analyze local requirements and respond to the needs of Iranian learners to enhance the status of ELT in the country.

In a recent paper [PRE, vol. 78, 056202 (2008)] the trace formula for both the smooth and the oscillating parts of the resonance density was proposed and checked for the circular cavity. The present paper deals with numerous shapes which would be integrable (square, rectangle, and ellipse), pseudo-integrable (pentagon) and chaotic (stadium), if the cavities were closed (billiard case). A good agreement is found between the theoretical predictions, the numerical simulations, and experiments based on organic micro-lasers.

L?alternanza argomentale locativa in ceco: un approccio costruzionista

description: This paper deals with the relationship between verbs and their arguments, investigating the so called locative alternation in Czech in the light of the the Construction Grammar Approach. On this basis the two alterning constructions, i.e. the causative movement construction and the resultative one, are seen to be linked by a metaphorical relation, the resultative construction being a metaphorical extension of the causative movement one. On the basis of their lexical meaning, the author defines four classes of verbs, which allow the locative alternation in Czech. A particular attention is devoted to the role of verbal prefixes in allowing or disallowing the verbs to appear in both constructions, which form the locative alternation: while prefix na- is claimed to allow the verbs to appear in both constructions, the causative movement construction and the resultative one, the prefix po- is claimed to allow the verbs to appear just in the resultative construction.

description: We report effective hole mass ($m^{*}$) measurements through analyzing the temperature dependence of Shubnikov-de Haas oscillations in dilute (density $p \sim 7 \times 10^{10}$ cm$^{-2}$, $r_{s} \sim 6$) two-dimensional (2D) hole systems confined to a 20 nm-wide, (311)A GaAs quantum well. The holes in this system occupy two nearly-degenerate spin subbands whose $m^{*}$ we measure to be $\sim $ 0.2 (in units of the free electron mass). Despite the relatively large $r_{s}$ in our 2D system, the measured $m^{*}$ is in good agreement with the results of our energy band calculations which do not take interactions into account. We hen apply a sufficiently strong parallel magnetic field to fully depopulate one of the spin subbands, and measure $m^{*}$ for the populated subband. We find that this latter $m^{*}$ is surprisingly close to the $m^{*}$ we measure in the absence of the parallel field. We also deduce the spin susceptibility of the 2D hole system from the depopulation field, and conclude that the susceptibility is enhanced by about 50% relative to the value expected from the band calculations.

description: Community detection methods have so far been tested mostly on small empirical networks and on synthetic benchmarks. Much less is known about their performance on large real-world networks, which nonetheless are a significant target for application. We analyze the performance of three state-of-the-art community detection methods by using them to identify communities in a large social network constructed from mobile phone call records. We find that all methods detect communities that are meaningful in some respects but fall short in others, and that there often is a hierarchical relationship between communities detected by different methods. Our results suggest that community detection methods could be useful in studying the general mesoscale structure of networks, as opposed to only trying to identify dense structures.

description: In this paper we introduce a notion of magnetic field in the Heisenberg group and we study its influence on spectral properties of the corresponding magnetic (sub-elliptic) Laplacian. We show that uniform magnetic fields uplift the bottom of the spectrum. For magnetic fields vanishing at infinity, including Aharonov--Bohm potentials, we derive magnetic improvements to a variety of Hardy-type inequalities for the Heisenberg sub-Laplacian. In particular, we establish a sub-Riemannian analogue of Laptev and Weidl sub-criticality result for magnetic Laplacians in the plane. Instrumental for our argument is the validity of a Hardy-type inequality for the Folland--Stein operator, that we prove in this paper and has an interest on its own.

Financing coffee farmers in Ethiopia: challenges and opportunities

Year: 2007

description: Notwithstanding the severe price shocks that have been shacking its value chain, coffee remains a fundamental component of the Ethiopian economy and export. Nevertheless the prolonged price decline has substantially weakened its production basis and prospects, so that appropriate financial services are urgently needed to sustain rural communities. To gather focused evidence on the financial supply and demand of small Ethiopian coffee producers, in 2005 we carried out an original survey interviewing 120 farmers from the Jimma zone (Oromia regional state); further, the statistical analysis was complemented by ?focus group? discussions and individual interviews with ?key-experts? of the coffee value chain. Several important findings emerge from this study. First, there is a strong evidence of an overall gap between demand and supply of financial services across the different sources (formal and informal ones). Second, informal financial services (loans) are very costly, while those from microfinance institutions (MFI) and cooperatives often appear not tailored to the farmers? needs (in relation to timing, length and amounts). Concerning saving products, their diffusion is still very limited, because they have been recently introduced, but in the future they could become an important component for strengthening the microfinance outreach; currently, they also stand as a substitute for risk-insurance products, totally absent in the Ethiopian coffee production chain. Regarding policy recommendations, the main priorities appear those of enlarging the outreach of MFI and financialy active cooperatives. More generally, a need emerges for demand-oriented financial services and suitable ?bottom-up? agricultural development and policy-making.

description: We discuss flavor mixing and resulting Flavor Changing Neutral Current (FCNC) in the SU(3) \otimes SU(3)_color gauge-Higgs unification. As the FCNC process we calculate the rate of D^0-\bar D^0 mixing due to the exchange of non-zero Kaluza-Klein gluons at the tree level. Flavor mixing is argued to be realized by the fact that the bulk mass term and brane localized mass term is not diagonalized simultaneously unless bulk masses are degenerate. It is shown that automatic suppression mechanism is operative for the FCNC processes of light quarks. We therefore obtain a lower bound on the compactification scale of order \cal O(TeV) by comparing our prediction on the mass difference of neutral D meson with the recent experimental data, which is much milder than what we naively expect assuming only the decoupling of non-zero Kaluza-Klein gluons.

THE POLITICAL ECONOMY OF MONETARY FOLLOWERSHIP IN SURPLUS COUNTRIES. THE DIVIDE BETWEEN SMALL AND MIDDLE POWERS
Creators: name: RAICO, NICOLO'
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: This research is about the impact of states? financial size on their choices in the field of monetary and exchange rate policy. The main argument of the thesis is that small countries, under certain conditions, can be counterintuitively more autonomous in these policy dimensions than middle-sized states. This conclusion, and its corollaries, proceed from the unsatisfactory explanation given by the present literature, in both economics and political science, to the policy outcomes observed in small states, and results from an original application of the Collective Choice Theory to strategic interactions within asymmetrical monetary systems. A model is designed to depict an international payment system led by a leader country with significant balance-of-payment problems, surrounded by minor states characterised by a persistent record of current account surplus. The model investigates the impact of financial size on the bargaining among small and medium-sized states for the preservation of policy autonomy vis � vis an interdependent economic environment. States are supposed to select one of two alternatives between following the leader?s policies, so as to support the stability of the system, or remaining neutral, so as to pursue domestic-oriented goals. The results, both on the theoretical and the empirical side, show that small surplus countries, under the assumptions of the model, are averagely more autonomous than middle powers, that is, less prone to take on responsibility for the smooth functioning of an international payment system. In turn, this makes traditional theories incomplete in the explanation of monetary followership in small countries, while the present model explains this phenomenon through the action of neighbouring middle powers in providing selective incentives.

Lavoratori e promozione dell'integrit� nel settore sanitario: tra profili teorici ed evidenze empiriche
Creators: name: VIALE, GABRIELLA
Publisher: name: Universit� degli studi di Bergamo
Year: 2017

description: La presente ricerca indaga il settore sanitario dal punto di vista dell?evoluzione del mercato del lavoro e dell?urgenza (particolarmente avvertita nel settore) di promuovere una maggiore integrit� a fronte dei crescenti casi di corruzione e malamministrazione al suo interno. Il tentativo � di leggere la realt� del fenomeno da un punto di vista diverso, ovvero partendo dal mercato del lavoro e dai lavoratori, dal ruolo che pu� avere anche l?organizzazione aziendale nel promuovere l?integrit� attraverso la fidelizzazione, il benessere organizzativo, la valorizzazione della persona e delle sue competenze.
Partendo da un?analisi della letteratura esistente sul tema (nella Literature Review) e da un?analisi quantitativa dei dati sul personale (tema approfondito nel primo capitolo) che evidenzia il crescente utilizzo dei contratti flessibili e atipici e, soprattutto, un crescente ricorso all?outsourcing (difficilmente traducibile in termini numerici di lavoratori impiegati), la ricerca si propone di esplorare come il cambiamento verso un sistema sanitario pi� integro, oltre che efficiente ed efficace, non possa essere affidato esclusivamente ad adempimenti puramente formali ma richiede uno sforzo in termini di investimento nel capitale umano, nella sua formazione e valorizzazione, nella diffusione delle tematiche etiche tra tutti i lavoratori che operano al suo interno. Quello che si � quindi voluto evidenziare, � se la gestione della promozione dell?integrit� (tema approfondito nel secondo capitolo) potrebbe essere complicata o venire gestita diversamente per la crescente diffusione delle tipologie contrattuali non-standard (lavoratori flessibili, atipici, autonomi e pseudo-autonomi, tirocinanti), tipologie di lavoro senza un contratto (voucher, lavoro nero) e di nuovi modelli di organizzazione del lavoro (economy on demand, smart-working, distacco di lavoratori forniti da agenzie di somministrazione dell?Est Europa) che portano a ridurre il perimetro del lavoro pubblico (su cui � centrata la l. n. 190/2012) a vantaggio di altri rapporti di lavoro, sia di natura subordinata che autonoma, pi� flessibili, meno costosi e meno garantiti rispetto al rapporto di lavoro pubblico e, pi� in generale, rispetto al lavoro subordinato.
L?analisi teorica � stata affiancata da una ricerca empirica condotta attraverso due metodologie differenti di analisi: un questionario inviato on-line ai Responsabili della Prevenzione della Corruzione che lavorano presso le aziende sanitarie italiane e una serie di interviste frontali ad un gruppo di testimoni, per cos� dire significativi (lavoratori dipendenti del SSN, soci di cooperative, lavoratori dipendenti di aziende socio-sanitarie private, lavoratori con partita IVA, sindacalisti, rappresentanti di ordini professionali, di associazioni di categoria, Responsabili della Prevenzione della Corruzione).

The speed of gravity in general relativity
Creators: name: Krasnikov, S.
Publisher: name: arXiv
Year: 2010
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The question is discussed of what is the speed of gravity (at the fundamental non-perturbative level). The question is important, if nowhere else, in discussing the problem of information "lost" in black holes. It turns out that the duly defined "gravitational signal" generally may be causal, superluminal and "semi-superluminal". In the class of globally hyperbolic spacetimes the two last varieties coincide. And if some (often imposed, but not always satisfied) conditions hold, the signals may be \emph{only} causal. In this sense the speed of gravity does not exceed the speed of light.

?Jetzt und in der Stunde unseres Todes?. Sterben und Tod im Mittelalter
Creators: name: D�WEL, KLAUS
Publisher: name: Universit� degli studi di Bergamo
Year: 2010

description: This contribution opens with a brief overview of representations of death (for instance The Grim
Reaper) as well as of the literary genres and forms concerned with the ideas of dying and death,
such as Memento mori, Vado mori, Dance of Death, the Legend of the Three Living and the Three
Dead. The fear of a sudden death, one that jeopardises the salvation of one?s soul in the afterlife,
stimulated the emergence of the ars moriendi, the art of dying, of which widespread evidence is also
found in wood engravings ? with or without accompanying text. Crucial to this investigation is the
German version of ars moriendi by Thomas Peuntner, Kunst des heilsamen Sterbens (1434), whose
adhortationes, interrogationes, orationes, and observationes contain a series of considerations and
pieces of advice that could demonstrably be useful, if only slightly adapted, even today. Employed
from an early stage and used continually since, the ars moriendi thus proves to be the art of living
and dying at the same time.

description: This study presents a method to discover an outbreak of an infectious disease in a region for which data are missing, but which is at work as a disease spreader. Node discovery for the spread of an infectious disease is defined as discriminating between the nodes which are neighboring to a missing disease spreader node, and the rest, given a dataset on the number of cases. The spread is described by stochastic differential equations. A perturbation theory quantifies the impact of the missing spreader on the moments of the number of cases. Statistical discriminators examine the mid-body or tail-ends of the probability density function, and search for the disturbance from the missing spreader. They are tested with computationally synthesized datasets, and applied to the SARS outbreak and flu pandemic.

Temporal Proteomic and Lipidomic Analysis of Lytic and Lysogenic Mycobacteriophage
Creators: name: Novak, Lauren E
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Agricultural biotechnology not elsewhere classified

description: Phages are viruses that infect bacteria and use its host machinery to replicate. They are one of the most ubiquitous and diverse biological entities in the biosphere with a long evolutionary history. There is renewed interest in phage therapeutics due to increased levels of antimicrobial resistance (AMR) and decreased numbers of newly developed antibiotics. Additionally, phages have applications in food safety, water quality, biocontrol, and vaccines. While many phage genomes have been sequenced and annotated, proteomic and lipidomic profiles of phage have barely been explored. The aim of this research is to measure the protein and lipid dynamics of phages with different infection cycles at different timepoints in the host’s growth cycle using mass spectrometry (MS). The data produced from this experiment can verify genomic annotation, discover novel proteins and lipids, and inspire future mechanistic and functional studies. For this study, Krili and PotatoSplit, lytic cluster O and lysogenic cluster A3 mycobacteriophages, were used to infect Mycobacterium smegmatis during the mid-exponential growth stage. Samples were taken in triplicate at hours 0.5 (immediately after infection), 3 (early exponential), 7 (late exponential), and 10 (early stationary). The samples were washed, mechanically lysed, quantified on BCA assay, lipid extracted, protein digested and desalted. For MS analysis, the samples were analyzed using a HPLC-ESI-MS/MS. Protein data was processed using MaxQuant and lipid data using MS-DIAL and MS-FINDER. Normalized data was statistically analyzed on MetaboAnalyst, correlated on JMP, and functionally analyzed using DAVID. The results showed that the protein and lipid expression of both phages differed with time in comparison to the control (uninfected Mycobacterium smegmatis) and to each other. Additionally, phage protein-lipid correlations suggest simultaneous phage infection and bacterial defense mechanisms particularly during late infection. Temporal and correlation data produced from this experiment can be used for future targeted -omics research. As one of the first experiments of its kind, the MS workflow used in this study can provide a scaffold for future phage temporal proteomic and lipidomic analysis.
title: Unravelling Cleopatra: a production history
Creators: name: Langley, M
Publisher: name: Bath Spa University

description: Using a wealth of extant and previously unreferenced evidence, this critical history reconstructs, examines, and interrogates Fox’s production of Cleopatra (Mankiewicz, 1963, Fox) from 1958-1966. The absence to date of an objective critical account means that for 60 years Cleopatra has acquired near-mythical status as one of Hollywood’s biggest flops, obscuring its pivotal role in the shift from the classical to the modern Hollywood system, and the impact of that shift upon Cleopatra’s production and subsequent reception. The critical history at the heart of this research considers how key events and decisions informed Cleopatra’s reaction to, and impact on, the economic and ideological shifts changing America’s mainstream film industry as all Hollywood sought to find a new way of working. This study therefore considers a pivotal moment in Hollywood’s conversion from the Classical to the Modern Studio System.
