description: Digitalisation, accelerated by the pandemic, has brought the opportunity for companies to expand their businesses beyond their geographic location and has considerably affected networks around the world. Cloud services have a better acceptance nowadays, and it is foreseen that this industry will grow exponentially in the following years. With more distributed networks that need to support customers in different locations, the model of one-single server in big financial centres has become outdated and companies tend to look for alternatives that will meet their needs, and this seems to be the case with Fortaleza, in Brazil. With several submarine cables connections available, the city has stood out as a possible hub to different regions, and this is what this paper explores. Making use of real traffic data through looking glasses, we established a latency classification that ranges from exceptionally low to high and analysed 800 latencies from Roubaix, Fortaleza and Sao Paulo to Miami, Mexico City, Frankfurt, Paris, Milan, Prague, Sao Paulo, Santiago, Buenos Aires and Luanda. We found that non-developed countries have a big dependence on the United States to route Internet traffic. Despite this, Fortaleza proves to be an alternative for serving different regions with relatively low latencies.

description: A cyber-physical system is considered to be a collection of strongly coupled communication systems and devices that poses numerous security trials in various industrial applications including healthcare. The security and privacy of patient data is still a big concern because healthcare data is sensitive and valuable, and it is most targeted over the internet. Moreover, from the industrial perspective, the cyber-physical system plays a crucial role in the exchange of data remotely using sensor nodes in distributed environments. In the healthcare industry, Blockchain technology offers a promising solution to resolve most securities-related issues due to its decentralized, immutability, and transparency properties. In this paper, a blockchain-inspired secure and reliable data exchange architecture is proposed in the cyber-physical healthcare industry 4.0. The proposed system uses the BigchainDB, Tendermint, Inter-Planetary-File-System (IPFS), MongoDB, and AES encryption algorithms to improve Healthcare 4.0. Furthermore, blockchain-enabled secure healthcare architecture for accessing and managing the records between Doctors and Patients is introduced. The development of a blockchain-based Electronic Healthcare Record (EHR) exchange system is purely patient-centric, which means the entire control of data is in the owner's hand which is backed by blockchain for security and privacy. Our experimental results reveal that the proposed architecture is robust to handle more security attacks and can recover the data if 2/3 of nodes are failed. The proposed model is patient-centric, and control of data is in the patient's hand to enhance security and privacy, even system administrators can't access data without user permission.

ACC/AHA guideline update for perioperative cardiovascular evaluation for noncardiac surgery - Executive summary: A report of the American College of Cardiology/American Heart Association Task Force on practice guidelines (Committee to Update the 1996 Guidelines on Perioperative Cardiovascular Evaluation for Noncardiac Surgery)
Creators: name: Smith, Sidney C., Jr.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: These guidelines represent an update of those published in 1996 and are intended for physicians who are involved in the preoperative, operative, and postoperative care of patients undergoing noncardiac surgery. They provide a framework for considering cardiac risk of noncardiac surgery in a variety of patient and surgical situations. The overriding theme of these guidelines is that preoperative intervention is rarely necessary simply to lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context. The purpose of preoperative evaluation is not simply to give medical clearance but rather to perform an evaluation of the patient’s current medical status; make recommendations concerning the evaluation, management, and risk of cardiac problems over the entire perioperative period; and provide a clinical risk profile that the patient, primary physician, anesthesiologist, and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes. The goal of the consultation is to identify the most appropriate testing and treatment strategies to optimize care of the patient, provide assessment of both short- and long-term cardiac risk, and avoid unnecessary testing in this era of cost containment.
The Real estate market: types of property and criteria for appraisal
Creators: name: Breglia, Mario
Publisher: name: Aestimum
Year: 2013

description: The increasing interest on the part of institutional investors in the yield potential of real estate assets highlights the importance of effective criteria for evaluation. Each segment of real estate needs its own appraisal procedure, which is determined according to the intended use of the property: residential, tertiary/offices, special use property. Special use properties are characterised by their individual nature, their particular intended use. They include university buildings, hospitals and barracks. These are all segments which are impossible to assess using criteria based on comparable sales or income capitalisation. Institutional investors are now particularly interested in asset divestment by the State and public bodies. The low level of risk of this kind of investment is likely to be particularly attractive to institutional players and could represent a good opportunity to revive the real estate market.

description: Background: Coronary Artery Disease (CAD) continues to be a significant burden in Malaysia that can lead to severe cardiac events and even death. Early interventions like cardiac rehabilitation programs can provide patients the necessary skills to recover from and prevent more cardiac events. EHealth interventions have great potential in complementing hospital based rehabilitation programs to improve the health of cardiac patients. Any behavior change interventions need to be guided by theories in order to obtain meaningful findings. This study aims to investigate the effectiveness of the Naluri app in improving clinical and psychological outcomes in a sample of cardiac patients in Malaysia. Methods: A randomised controlled trial was conducted whereby patients in the treatment group (n=84) downloaded and used the Naluri app for four months after recruitment. The control group (n=91) received usual care that included lifestyle counselling. The Health Action Process Approach (HAPA) theory was used as the theoretical framework for the Naluri app and to investigate patients’ intention, planning and action in improving diet and physical activity. The clinical and psychological outcomes included BMI, HbA1c, lipid levels, anxiety, depression and health-related quality of life. Results: The mixed methods analysis found that the Naluri app intervention was effective in increasing physical activity, specifically vigorous physical activity compared to the control group, F(1,173) = 8.47, p = .004, ηp2 = .047. The app was not effective in improving diet, clinical and psychological outcomes. The HAPA theory was a useful theoretical framework to explain patients' health behaviour change. Perceived facilitators and barriers to behaviour change include intra- and interpersonal factors. There was high acceptability of the app although attrition rate was high due to issues with instability and complexity of the app. Conclusion: The Naluri app can be a useful tool in improving physical activity among CAD patients. However, further improvements on the app are required to maximize patient engagement.
Testing the use of Contingent Valuation Method in Real Estate Market: first results of an experiment in the city of Milan

description: One of the most criticism in Real Estate appraisal processes based on sales comparison approach is the reliability of data about market prices of comparable properties. In this context, the use of evaluation methods based on hypothetical markets, most widely used in the field of the evaluation of environmental goods or cultural heritage, could solve that problem. It has been found that estimating the willing to pay (WTP) for a sample of goods with different features brings to reliable outcomes with negligible gaps by comparison with the values obtained by the more traditional real estate appraisal methods. According to these general assumptions, the paper suggests the use of Contingent Valuation Method with the aim of replace in the appraisal models the market prices of a sample of properties with the WTP for the same goods.

description: Based on the sense definition of words available in the Bengali WordNet, an attempt is made to classify the Bengali sentences automatically into different groups in accordance with their underlying senses. The input sentences are collected from 50 different categories of the Bengali text corpus developed in the TDIL project of the Govt. of India, while information about the different senses of particular ambiguous lexical item is collected from Bengali WordNet. In an experimental basis we have used Naive Bayes probabilistic model as a useful classifier of sentences. We have applied the algorithm over 1747 sentences that contain a particular Bengali lexical item which, because of its ambiguous nature, is able to trigger different senses that render sentences in different meanings. In our experiment we have achieved around 84% accurate result on the sense classification over the total input sentences. We have analyzed those residual sentences that did not comply with our experiment and did affect the results to note that in many cases, wrong syntactic structures and less semantic information are the main hurdles in semantic classification of sentences. The applicational relevance of this study is attested in automatic text classification, machine learning, information extraction, and word sense disambiguation.

description: In this paper we tackle the problem of surfactant spreading on a thin liquid film in the framework of isogeometric analysis. We consider a mathematical model that describes this phenomenon as an initial boundary value problem (IBVP) that includes two coupled fourth order partial differential equations (PDEs), one for the film height and one for the surfactant concentration. In order to solve this problem numerically, it is customary to transform it into a mixed problem that includes at most second order PDEs. However, the higher-order continuity of the approximation functions in Isogeometric Analysis (IGA) allows us to deal with the weak form of the fourth order PDEs directly, without the need of resorting to mixed methods. We demonstrate numerically that the IGA solution is able to reproduce results obtained before with mixed approaches. Complex phenomena such as Marangoni-driven fingering instabilities triggered by perturbations are easily captured.

ACC/AHA/SCAI 2005 guideline update for Percutaneous Coronary Intervention: A report of the American College of Cardiology/American Heart Association Task Force on practice guidelines (ACC/AHA/SCAI Writing Committee to update the 2001 guidelines for Percutaneous Coronary Intervention)
Creators: name: Smith, Sidney C., Jr.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: "The ACC/AHA Task Force on Practice Guidelines was formed to gather information and make recommendations about appropriate use of technology for the diagnosis and treatment of patients with cardiovascular disease. Percutaneous coronary interventions (PCIs) are an important group of technologies in this regard. Although initially limited to balloon angioplasty and termed percutaneous transluminal coronary angioplasty (PTCA), PCI now includes other new techniques capable of relieving coronary narrowing. Accordingly, in this document, implantation of intracoronary stents and other catheter-based interventions for treating coronary atherosclerosis are considered components of PCI. In this context, PTCA will be used to refer to those studies using only balloon angioplasty, whereas PCI will refer to the broader group of percutaneous techniques. These new technologies have impacted the effectiveness and safety profile initially established for balloon angioplasty. Moreover, additional experience has been gained in the use of adjunctive pharmacological treatment with glycoprotein (GP) IIb/IIIa receptor antagonists and the use of bivalirudin, thienopyridines, and drug-eluting stents (DES). In addition, since publication of the guidelines in 2001, greater experience in the performance of PCI in patients with acute coronary syndromes and in community hospital settings has been gained. In view of these developments, an update of these guidelines e168 Circulation February 21, 2006 is warranted. This document reflects the opinion of the ACC/AHA/SCAI writing committee charged with updating the 2001 guidelines for PCI (1)."
title: The technical recipe: a formal analysis of nineteenth-century food writing
Creators: name: Middleton, Lindsay
Publisher: name: University of Glasgow
Year: 2023

description: In my thesis, I apply a literary analysis to nineteenth-century recipes and cookbooks to interrogate the period’s overarching discourses of historicity and innovation. I argue that food writing was a literary genre in which authors constructed, enacted, and questioned their relationship to the past, present, and future. I analyse the literary techniques that nineteenth-century authors utilised within recipes and cookbooks, arguing that they were inherently literary texts that communicated more than practical instructions. I demonstrate that recipes and cookbooks formed a vital part of the nineteenth-century literary marketplace, becoming sites where important debates concerning globalisation, class, and gender played out. Central to my analysis are the links between food writing and material technologies. I posit that recipes and cookbooks were literary technologies, written to help readers make sense of material implements and cooking processes. Authors wove narratives of tradition and innovation around material implements in their culinary writing, and I unravel those narratives to illuminate how technological discussions percolated through domestic texts. To investigate the preoccupation with historicity and innovation in food writing fully, my thesis contains a two-fold methodology and structure. Chapters One and Two are based on the structural breakdown of a data set of recipes which refer to specific material technologies. Chapter One investigates representations of the gridiron: an implement with a longstanding history of tradition and cultural symbolism. In Chapter Two I turn to tinned foods: an innovation that was new within my chosen period. This delineation of a data set of recipes allows me to analyse how technologies were interpreted by multiple authors and to argue that recipes are worthy of sustained analysis as individual literary forms. In Chapters Three and Four, I turn to entire cookbooks to investigate how authors utilised literary techniques across whole texts. In Chapter Three I study the cookbooks of Alexis Soyer, a chef with a marked interest in technological innovations and history. Chapter Four considers the works of Agnes Marshall and Georgiana Hill, two successful cookbook authors who employed very different kinds of rhetorical innovation to depart from traditions. I use this whole-text analysis to question how authors engaged with the wider literary culture of the nineteenth century, subverting the expectations that governed the cookbook genre to engage with discourses of historicity and innovation.

description: Il nostro presente è un tempo di tempesta, tempo di rottura della “normalità”, tempo di interregno in cui, in attesa di concetti nuovi, proliferano le metafore. Virosfera è una di queste. L’A. ritiene necessario  bandire dal nostro lessico categorie fuorvianti come “parentesi”, “interruzione” e simili. La radicalità e ampiezza della pandemia determina un punto di svolta tale da pregiudicare le stesse idee di cambiamento, progresso, innovazione come le abbiamo finora intese e praticate. La pandemia che stiamo vivendo non è dunque un “cigno nero”: un evento inatteso e imprevedibile e non è indipendente da noi. È un disastro prodotto da noi con alterazioni traumatiche nella natura, e che mette a nudo la nostra vulnerabilità. Da qui la parola-chiave è resilienza.

Our time is a stormy one, a time of breaking down ‘normality’, a time of interregnum in which, while waiting for new concepts, metaphors are flourishing. Virosphere is one of these. The author considers necessary to banish misleading categories such as “parenthesis”, “interruption” from our lexicon.  The radicality and extension of the pandemic determines a turning point such as to undermine the very ideas of change, progress and innovation as we have hitherto understood and applied them. The pandemic we are experiencing is therefore not a ‘black swan’: it is an unexpected and unpredictable event and is not independent of us. It is a disaster produced by us with traumatic alterations in nature, and which reveals our vulnerability. Hence the key word is resilience.

description: The estimate of undivided and indivisible real estate shares, in relation to different building types represents, in practice application, a recurring underestimated by the professional appraisers. This problem requires finding a logical solution that can to rationalize the process the process of estimation of undivided shares, given that these shares are more difficult to sell and, consequently, there is a decrease of their market value. It follows that in this estimative case the problem can be lead, both in theoretical and practical terms, to assessment of specific real estate investment’s risk and how to convert the measure of risk into an expected return that can compensate it. In this framework, the proposed contribution aims to implement the Capital Asset Pricing Model with Penalized Spline Semiparametric Method in order to obtain an estimation algorithm that allows to rationalize the approach to the problem of estimation of undivided real estate shares using data easy to find.

description: The construction of hedonimetric curves is proposed as an approach to assess public or semi-public goods in urban areas. These resources are not considered in the appraisal theory based on “Serpieri paradigm” and addressed to value private properties. Using a plurality of hedonic prices it is possible to attribute a use value to piazza Mercato in Naples derived from its attractiveness. The value judgment employs a monetary component and other components generally expressed in non-monetary units. The first one is taken from prices and characteristics of habitations around this historical space solving linear multiple regression models. The other ones depend on environmental, social and economic qualities of its surrounding area in rela- tion to the city and to the port.

description: Many infrastructure networks have a modular structure and are also interdependent. While significant research has explored the resilience of interdependent networks, there has been no analysis of the effects of modularity. Here we develop a theoretical framework for attacks on interdependent modular networks and support our results by simulations. We focus on the case where each network has the same number of communities and the dependency links are restricted to be between pairs of communities of different networks. This is very realistic for infrastructure across cities. Each city has its own infrastructures and different infrastructures are dependent within the city. However, each infrastructure is connected within and between cities. For example, a power grid will connect many cities as will a communication network, yet a power station and communication tower that are interdependent will likely be in the same city. It has been shown that single networks are very susceptible to the failure of the interconnected nodes (between communities) Shai et al. and that attacks on these nodes are more crippling than attacks based on betweenness da Cunha et al. In our example of cities these nodes have long range links which are more likely to fail. For both treelike and looplike interdependent modular networks we find distinct regimes depending on the number of modules, $m$. (i) In the case where there are fewer modules with strong intraconnections, the system first separates into modules in an abrupt first-order transition and then each module undergoes a second percolation transition. (ii) When there are more modules with many interconnections between them, the system undergoes a single transition. Overall, we find that modular structure can influence the type of transitions observed in interdependent networks and should be considered in attempts to make interdependent networks more resilient.

description: Antiferromagnetic (AF) materials are attracting increasing interest of research in magnetic physics and spintronics. Here, we report controllable synthesis of room-temperature AF $α$-MnTe nanocrystals (Néel temperature ~ 307 K) via molten-salt-assisted chemical vapor deposition method. The growth kinetics are investigated regarding the dependence of flake dimension and macroscopic shape on growth time and temperature. The high crystalline quality and atomic structure are confirmed by various crystallographic characterization means. Cryogenic magneto-transport measurements reveal anisotropic magnetoresistance (MR) response and a complicated dependence of MR on temperature, owing to the subtle competition among multiple scattering mechanisms of thermally excited magnetic disorders (magnon drag), magnetic transition and thermally populated lattice phonons. Overall positive MR behavior with twice transitions in magnitude is observed when out-of-plane external magnetic field ($B$) is applied, while a transition from negative to positive MR response is recorded when in-plane $B$ is applied. The rich magnetic transport properties render $α$-MnTe a promising material for exploiting functional components in magnetic devices.

description: The roll calls of the Italian Parliament in the XVI legislature are studied by employing multidimensional scaling, hierarchical clustering, and network analysis. In order to detect changes in voting behavior, the roll calls have been divided in seven periods of six months each. All the methods employed pointed out an increasing fragmentation of the political parties endorsing the previous government that culminated in its downfall. By using the concept of modularity at different resolution levels, we identify the community structure of Parliament and its evolution in each of the considered time periods. The analysis performed revealed as a valuable tool in detecting trends and drifts of Parliamentarians. It showed its effectiveness at identifying political parties and at providing insights on the temporal evolution of groups and their cohesiveness, without having at disposal any knowledge about political membership of Representatives.

description: In this paper, we explore the role that attribution plays in shaping user reactions to content reuse, or remixing, in a large user-generated content community. We present two studies using data from the Scratch online community -- a social media platform where hundreds of thousands of young people share and remix animations and video games. First, we present a quantitative analysis that examines the effects of a technological design intervention introducing automated attribution of remixes on users' reactions to being remixed. We compare this analysis to a parallel examination of "manual" credit-giving. Second, we present a qualitative analysis of twelve in-depth, semi-structured, interviews with Scratch participants on the subject of remixing and attribution. Results from both studies suggest that automatic attribution done by technological systems (i.e., the listing of names of contributors) plays a role that is distinct from, and less valuable than, credit which may superficially involve identical information but takes on new meaning when it is given by a human remixer. We discuss the implications of these findings for the designers of online communities and social media platforms.

description: The importance of the valuation of public goods is growing. In fact, only by determining the economic value of these assets is possible to determine the efficiency of the investments and of the maintenance. The problems in estimating the total economic value relate to two fundamental aspects: the choice and implementation of the more accurate evaluation methodology and the identification of the universe of users. In literature, in fact, the issue of the universe is often resolved by considering the number of potential users (be they the inhabitants of a city, a neighborhood, a street, etc..) and not the actual visitors. This leads to an underestimation or an overestimation of the use value of public goods. The objective of this research is to focus on this issue by proposing a specific methodological approach to correctly estimate the universe of the actual users of different urban green areas of Florence.

description: The evolution of a pulsar wind nebula (PWN) inside a supernova remnant (SNR) is sensitive to properties of the central neutron star, pulsar wind, progenitor supernova, and interstellar medium. These properties are both difficult to measure directly and critical for understanding the formation of neutron stars and their interaction with the surrounding medium. In this paper, we determine these properties for PWN G54.1+0.3 by fitting its observed properties with a model for the dynamical and radiative evolution of a PWN inside an SNR. Our modeling suggests that the progenitor of G54.1+0.3 was an isolated ~15-20 Solar Mass star which exploded inside a massive star cluster, creating a neutron star initially spinning with period ~30-80ms. We also find that >99.9% of the pulsar's rotational energy is injected into the PWN as relativistic electrons and positrons whose energy spectrum is well characterized by a broken power-law. Lastly, we propose future observations which can both test the validity of this model and better determine the properties of this source -- in particular, its distance and the initial spin period of the central pulsar.

description: L’articolo presenta i risultati di una ricerca svolta a Firenze, il cui obiettivo è quello di comprendere meglio le modalità di relazione tra scuola e famiglia immigrata nella scuola dell’infanzia. Essa è stata realizzata nell’ambito di un progetto PRIN (Programma di ricerca scientifica di rilevante interesse nazionale) coordinato a livello nazionale da Susanna Mantovani e che oltre a Milano ha coinvolto altre tre città: Roma, Firenze e Parma. L’unità di ricerca dell’università di Firenze, ha esplorato tramite due questionari – uno rivolto agli insegnanti, l’altro ai genitori – il tema della relazione tra insegnanti e genitori immigrati nella realtà fiorentina. I risultati appaiono incoraggianti, visto che le insegnanti mostrano grande disponibilità all’ascolto, mentre i genitori immigrati rilevano un buon livello di integrazione, anche se talvolta criticano il carattere a loro dire eccessivamente ludico della scuola dell’infanzia.

description: Social media platforms have emerged as prominent information sharing ecosystems in the context of a variety of recent crises, ranging from mass emergencies, to wars and political conflicts. We study affective responses in social media and how they might indicate desensitization to violence experienced in communities embroiled in an armed conflict. Specifically, we examine three established affect measures: negative affect, activation, and dominance as observed on Twitter in relation to a number of statistics on protracted violence in four major cities afflicted by the Mexican Drug War. During a two year period (Aug 2010-Dec 2012), while violence was on the rise in these regions, our findings show a decline in negative emotional expression as well as a rise in emotional arousal and dominance in Twitter posts: aspects known to be psychological markers of desensitization. We discuss the implications of our work for behavioral health, facilitating rehabilitation efforts in communities enmeshed in an acute and persistent urban warfare, and the impact on civic engagement.

description: In a hierarchical nanopatterning routine relying exclusively on self-assembly processes we combine crystal surface reconstruction, microphase separation of copolymers, and selective metal diffusion to produce monodisperse metal nanostructures in highly regular arrays covering areas of square centimeters. In-situ GISAXS during Fe nanostructure formation evidences the outstanding structural order in the self-assembling system and hints at possibilities of sculpting nanostructures by external process parameters. Thus, we demonstrate that nanopatterning via self-assembly is a competitive alternative to lithography-based routines, achieving comparable pattern regularity, feature size, and patterned areas with considerably reduced effort. The option for in-situ investigations during pattern formation, the possibility of customizing the nanostructure morphology, the capacity to pattern arbitrarily large areas with ultra-high structure densities, and the potential of addressing the nanostructures individually enable numerous applications, e.g., in high-density magnetic data storage, in functional nanostructured materials, e.g., for photonics or catalysis, or in sensing based on surface plasmon resonances.

Voci di famiglie immigrate e insegnanti a confronto: una riflessione su alcuni focus group condotti nelle scuole dell’infanzia fiorentine

description: L’articolo prende in esame la realtà relazionale che lega famiglie immigrate e scuola dell’infanzia, attraverso l’analisi di quattro focus group condotti nella scuola dell’infanzia dell’Istituto degli Innocenti di Firenze con genitori e insegnanti. Il lavoro svolto mette in luce alcuni aspetti relativi alle aspettative reciproche di scuola e famiglia ed a quanto queste possano condizionare la concreta realizzazione del legame. Dalle parole di insegnanti e genitori emergono alcune considerazioni soprattutto in relazione alla lingua, alle finalità della scuola dell’infanzia, al significato di accoglienza. Temi non semplici, dunque, intorno ai quali occorre riflettere in più direzioni, ascoltando le voci di tutti gli attori sociali coinvolti, nell’intento di trovare risposte plurali capaci di valorizzare comunanze e differenze. In questo senso diventa allora fondamentale puntare su una formazione delle insegnanti che miri all’acquisizione di competenze relazionali e riflessive in grado di stimolare l’apertura e il decentramento. Allo stesso modo occorrerà prevedere sempre più spazi di incontro dedicati a insegnanti e genitori, in modo da consentire loro di conoscersi e confrontarsi, per potenziare il dialogo e scongiurare il rischio di cronicizzare eventuali conflitti.

Quantum spin Hall effect in strained (111)-oriented SnSe layers

description: Recently, the quantum spin Hall effect has been predicted in (111)-oriented thin films of SnSe and SnTe topological crystalline insulators. It was shown that in these films the energy gaps in the two-dimensional band spectrum depend in an oscillatory fashion on the layer thickness -- the calculated topological invariant indexes and edge state spin polarizations show that for films 20-40 monolayers thick a two-dimensional topological insulator phase appears. Edge states with Dirac cones with opposite spin polarization in their two branches are obtained for both materials. However, for all but the (111)-oriented SnTe films with an even number of monolayers an overlapping of bands in $\overlineΓ$ and $\overline{\mathrm{M}}$ diminishes the final band gap and the edge states appear either against the background of the bands or within a very small energy gap. Here we show that this problem in SnSe films can be removed by applying an appropriate strain. This should enable observation of the Quantum Spin Hall effect also in SnSe layers.

description: We present the results of the covariant spectator quark model applied to the nucleon structure function $f(x)$ measured in unpolarized deep inelastic scattering, and the structure functions $g_1(x)$ and $g_2(x)$ measured in deep inelastic scattering using polarized beams and targets ($x$ is the Bjorken scaling variable). The nucleon is modeled by a valence quark-diquark structure with $S,P$ and $D$ components. The shape of the wave functions and the relative strength of each component are fixed by making fits to the deep inelastic scattering data for the structure functions $f(x)$ and $g_1(x)$. The model is then used to make predictions on the function $g_2(x)$ for the proton and neutron.

description: In this paper we examine the information sharing practices of people living in cities amid armed conflict. We describe the volume and frequency of microblogging activity on Twitter from four cities afflicted by the Mexican Drug War, showing how citizens use social media to alert one another and to comment on the violence that plagues their communities. We then investigate the emergence of civic media "curators," individuals who act as "war correspondents" by aggregating and disseminating information to large numbers of people on social media. We conclude by outlining the implications of our observations for the design of civic media systems in wartime.
