The extraordinariness of ordinariness in tourism research
Creators: name: Blichfeldt, Bodil Stilling
name: Mikkelsen, Marie
Publisher: name: Journal of Tourism & Development
Year: 2014

description: This theoretical paper discusses extraordinariness and peak experiences as a dominant discourse in tourist studies and points to ordinariness as an equally important, albeit under-researched, dimension of holidaying. Drawing in issues such as multiple dwellings, connected worlds, thick sociality, vacability and mundane holidays, the paper questions the viability and relevance of the dominant research discourse and asks whether it is perhaps time to introduce ordinariness as a complementary discourse that could be of benefit to future tourist studies.

description: A imagem de destinos turísticos é um conceito amplamente estudado, complexo e multidimensional. A literatura indica que a imagem é determinante no comportamento dos visitantes perante o destino. Neste sentido, a gestão de marketing torna-se fundamental para o sucesso dos destinos turísticos. Os investigadores e especialistas de marketing em turismo devem prestar especial atenção ao tema da imagem que se mostra de relevância para as estratégias de promoção de destinos. Este é um dos enfoques principais do presente estudo, assim como analisar o caminho da investigação sobre a imagem de Portugal como destino turístico. A presente investigação permite concluir que, em Portugal, a investigação sobre a imagem mostra-se pouco orientada em vários aspetos. Esta deve ser reorientada de maneira a conseguir-se concluir sobre as discrepâncias e semelhanças entre a imagem percebida pelos visitantes e a imagem projetada pelos responsáveis dos destinos. Algumas implicações são apontadas, assim como orientações para a investigação futura sobre a imagem em Portugal.

description: The Atlas3D project is a multi-wavelength survey combined with a theoretical modeling effort. The observations span from the radio to the millimeter and optical, and provide multi-colour imaging, two-dimensional kinematics of the atomic (HI), molecular (CO) and ionized gas (Hbeta, [OIII] and [NI]), together with the kinematics and population of the stars (Hbeta, Fe5015 and Mgb), for a carefully selected, volume-limited (1.16*10^5 Mpc^3) sample of 260 early-type (elliptical E and lenticular S0) galaxies (ETGs). The models include semi-analytic, N-body binary mergers and cosmological simulations of galaxy formation. Here we present the science goals for the project and introduce the galaxy sample and the selection criteria. The sample consists of nearby (D<42 Mpc) morphologically-selected ETGs extracted from a parent sample of 871 galaxies (8% E, 22% S0 and 70% spirals) brighter than M_K6*10^9 M_Sun). We analyze possible selection biases and we conclude that the parent sample is essentially complete and statistically representative of the nearby galaxy population. We present the size-luminosity relation for the spirals and ETGs and show that the ETGs in the Atlas3D sample define a tight red sequence in a colour-magnitude diagram, with few objects in the transition from the blue cloud. We describe the strategy of the SAURON integral-field observations and the extraction of the stellar kinematics with the pPXF method. We give an overview of the characteristics of the other main datasets already available for our sample and of the ongoing modelling projects.

‘Mergulhar num mundo mágico’: a promoção do rural em três redes de aldeias em Portugal
Creators: name: Capela, Catarina

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: A valorização crescente das áreas rurais como espaços orientados para consumo decorre de diversos processos de transformação, sobretudo dos que se relacionam com a perda de relevância socioeconómica da atividade que tradicionalmente os caracterizava – a agricultura. Na sequência destes processos, numa boa parte do território rural português, o turismo e as atividades associadas têm-se constituído como centrais, sendo frequentemente apontados como mecanismos de revitalização e desenvolvimento local. A promoção turística constitui-se como um aspeto muito relevante na representação, consumo e reconfiguração de muitos destes territórios, contribuindo para a formação de um imaginário social sobre o rural através da sua apresentação frequente como espaço idílico e pleno de oportunidades de recreio. Com base na análise de conteúdo dos materiais promocionais (textuais e visuais) das redes das Aldeias do Xisto, Aldeias Históricas de Portugal e Aldeias Vinhateiras, foi analisado o modo como o rural e a ruralidade são promovidos, destacando os principais símbolos e narrativas utilizadas1. Os resultados obtidos demonstram que os materiais promocionais das três Redes mobilizam de forma combinada símbolos e elementos, materiais e imateriais, de caráter local e global. Tais símbolos e elementos parecem ser crescentemente transformados em produtos e experiências comercializáveis.

The effect of continual antigenic stimulation on the immune system of mice
Creators: name: McMaster, William Robert
Publisher: name: University of British Columbia
Year: 2010

description: The effect of continual antigenic stimulation on the immune system of mice was studied using two different experimental approaches. A GVHR was induced in Fi mice by the injection of parental spleen cells at weekly intervals. Several weeks later the spleen cells of mice undergoing a GVHR were shown to be immunosuppressed as their in vitro responses to the mitogens Con A and LPS were substancially lower than control animals. The serum from these treated mice was also immunosuppressive to normal spleen cells. The proliferative response to Con A and allogeneic cells of normal: syngeneic, allogeneic, and parental spleen cells was 90% suppressed when GVH serum was added in comparison to the addition of normal serum. Similarly, the in vitro antibody response to a T dependant antigen was impaired; however, the antibody response to a T independant antigen was not impaired. These results indicate that T cell functions are more sensitive than are B cell function to immunosuppressive factors in the serum of mice undergoing a GVHR. The serum was fractionated by gel filtration on a Bio-Gel P-200 column. The inhibitory material in GVH serum eluted in the immunoglobulin fraction of serum which indicate that it has a molecular weight of 150,000 or greater. The second approach studied involved continual allogeneic stimulation. Parental type mice were injected at five day intervals with Fi spleen cells in order to induce a HVG reaction. After several injections the spleen cells from these mice were tested in vitro. The spleen cells from HVG mice responded the same as normal spleen cells to the mitogens Con A and LPS. The spleen cells from HVG mice showed an enhanced in vitro antibody response as compared to normal spleen cells. This enhancement was attributed to the allogeneic effect. This series of experiments have shown that the induction of a GVHR in mice can later lead to immunosuppression and production of immunosuppressive factors in the serum of these mice. The induction of a short term HVG reaction has no adverse effects on the immune system except for enhancing an antibody response. It is possible that a more prolonged HVG reaction would parallel the immunosuppression observed in mice undergoing a GVHR.

“Mil emoções que brotam da terra”: as representações do rural nos materiais promocionais do Turismo de Portugal
Creators: name: Pinto, Cândido
name: Figueiredo, Elisabete
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: Neste trabalho parte-se do pressuposto que o turismo possui um papel crescentemente relevante na reconfiguração de uma boa parte dos territórios rurais do mundo ocidental, tanto em termos materiais como simbólicos, em consequência da progressiva constituição daqueles territórios como lugares de consumo, especialmente vocacionados para o recreio e o lazer. Assim, a promoção turística do rural tem, nos últimos anos, colocado maior ênfase nas características que o constituem como um espaço atrativo, pleno de oportunidades de recreio e capaz de proporcionar experiências únicas e completas, combinando a tradição e a modernidade. A promoção turística do rural sustenta-se no e simultaneamente faz apelo ao imaginário urbano sobre aquele território, apresentando-o como ‘idílico’, ‘autêntico’ e ‘genuíno’. Com base na análise de conteúdo das componentes textuais dos materiais destinados à promoção dos destinos rurais para o mercado interno, produzidos pelo Turismo de Portugal entre 1986 e 2012, procura-se analisar o modo como aqueles destinos são representados e debater as principais transformações nos símbolos e discursos utilizados. A evidência empírica demonstra uma clara orientação, nas duas últimas décadas, para a promoção do rural como espaço preservado e natural, vocacionado para os turistas, ao mesmo tempo que parece consolidar-se a negligência dos habitantes locais e das suas atividades.

An Analysis of the Multiplicity Spaces in Branching of Symplectic Groups

Publisher: name: arXiv
Year: 2009
Subjects: subject: Representation Theory (math.RT)
subject: Rings and Algebras (math.RA)

subject: 22E02

description: Branching of symplectic groups is not multiplicity-free. We describe a new approach to resolving these multiplicities that is based on studying the associated branching algebra $B$. The algebra $B$ is a graded algebra whose components encode the multiplicities of irreducible representations of $Sp_{2n-2}$ in irreducible representations of $Sp_{2n}$. Our first theorem states that the map taking an element of $Sp_{2n}$ to its principal $n \times (n+1)$ submatrix induces an isomorphism of $\B$ to a different branching algebra $\B'$. The algebra $\B'$ encodes multiplicities of irreducible representations of $GL_{n-1}$ in certain irreducible representations of $GL_{n+1}$. Our second theorem is that each multiplicity space that arises in the restriction of an irreducible representation of $Sp_{2n}$ to $Sp_{2n-2}$ is canonically an irreducible module for the $n$-fold product of $SL_{2}$. In particular, this induces a canonical decomposition of the multiplicity spaces into one dimensional spaces, thereby resolving the multiplicities.

Searching for Signatures of Cosmic Superstrings in the CMB

Year: 2009

description: Because cosmic superstrings generically form junctions and gauge theoretic strings typically do not, junctions may provide a signature to distinguish between cosmic superstrings and gauge theoretic cosmic strings. In cosmic microwave background anisotropy maps, cosmic strings lead to distinctive line discontinuities. String junctions lead to junctions in these line discontinuities. In turn, edge detection algorithms such as the Canny algorithm can be used to search for signatures of strings in anisotropy maps. We apply the Canny algorithm to simulated maps which contain the effects of cosmic strings with and without string junctions. The Canny algorithm produces edge maps. To distinguish between edge maps from string simulations with and without junctions, we examine the density distribution of edges and pixels crossed by edges. We find that in string simulations without Gaussian noise (such as produced by the dominant inflationary fluctuations) our analysis of the output data from the Canny algorithm can clearly distinguish between simulations with and without string junctions. In the presence of Gaussian noise at the level expected from the current bounds on the contribution of cosmic strings to the total power spectrum of density fluctuations, the distinction between models with and without junctions is more difficult. However, by carefully analyzing the data the models can still be differentiated.

Estimation of BVk functions from scattered data
Creators: name: Hu, Addison J.
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: subject: Statistics
subject: FOS: Mathematics

description:  The study of bounded variation (BV) functions, and its higher-order generalizations (BVk functions), is rooted in many ?elds: statistics, signal processing, functional analysis, approximation theory, among others. From these diverse perspectives has emerged a comprehensive theory of BVk functions and their estimation from noisy data in dimension d = 1. In dimension d > 1, the statistical picture is much less clear. Existing statistical theory for BVk functions can broadly broken down into two categories: replacing the continuous-time BVk function class with a discrete analogue; or retaining the continuous-time function class and using continuous-time loss (e.g., the white noise model). A gap in the literature lies in the estimation of functions from the continuous-time function class under a sampling model. This thesis is motivated by that gap. 
The second and third chapters address the problem of estimating BVk functions, for index values k = 0 and k = 1, using scattered data. These cases correspond to functions of bounded variation and functions whose gradient are bounded variation, respectively. For the k = 0 case, we study an estimator, the Voronoigram, which fits piecewise constant functions using the Voronoi tessellation of the sample locations. Using the Voronoigram, we establish that the minimax rate (up to log terms) over bounded variation classes is n −1/d. For the k = 1 case, we study an estimator, the Delaunaygram, which fits continuous piecewise linear functions using the Delaunay tessellation of the sample locations. We ?nd that the Delaunaygram has a n −4/(4+d) rate of convergence when d < 4 and n −2/d rate when d ≥ 4 over discrete gradient variation classes, and ob?tain matching minimax lower bounds over continuous gradient variation classes. We address the discrete-to-continuous gap, which we expect to be resolved in following work. Along the way, we explore methodological, computational, and practical properties of the two estimators. 
The final chapter addresses the broader goal of estimating of BVk functions, k ≥ 2. Special attention is called to the following topics: bounded variation classes for k ≥ 2; anticipated rates of convergence for BVk classes; challenges specific to dimension d > 1; and the desired properties of higher-order generalizations of the estimators studied in this thesis.

description: Let $k$ be a field of positive characteristic $p$. Question: Does every twisted form of $μ_p$ over $k$ occur as subgroup scheme of an elliptic curve over $k$? We show that this is true for most finite fields, for local fields and for fields of characteristic $p\leq11$. However, it is false in general for fields of characteristic $p\geq13$, which implies that there are also $p$-divisible and formal groups of height one over such fields that do not arise from elliptic curves. It also implies that the Hasse invariant does not obey the Hasse principle. Moreover, we also analyse twisted forms of $p$-torsion subgroup schemes of ordinary elliptic curves and the analogous questions for supersingular curves.

description: We investigate the problem of the typical rotation states of the small planetary satellites from the viewpoint of the dynamical stability of their rotation. We show that the majority of the discovered satellites with unknown rotation periods cannot rotate synchronously, because no stable synchronous 1:1 spin-orbit state exists for them. They rotate either much faster than synchronously (those tidally unevolved) or, what is much less probable, chaotically (tidally evolved objects or captured slow rotators).

description: La competitividad manifiesta que existe entre los destinos turísticos, junto a una oferta cada vez más variada y poco diferenciada, supone que los gestores apliquen nuevos métodos que puedan conseguir un mejor posicionamiento. De esta forma, la celebración de eventos gastronómicos implica un aspecto diferenciador para el turista en el proceso de elección del destino. El objetivo principal de este trabajo es profundizar en el estudio del perfil del turista gastronómico, mediante un estudio empírico cuantitativo sobre la demanda. El escenario de la investigación se desarrolla en dos eventos consolidados que se celebran en la región española de Extremadura, conocido destino cultural y de interior, como son la Fiesta del Cerezo en Flor en el Valle del Jerte y la Feria Nacional del Queso en Trujillo. Del estudio se derivan informaciones a tener en cuenta por las instituciones, ya que los resultados han permitido definir las características del turista gastronómico de este tipo de eventos como un viajero urbano, de edad intermedia, que pernocta en el destino y valora además de la gastronomía, la naturaleza y los paisajes.

description: Hospitals and health service providers are use to collect data about patient’s opinion to improve patient health status and communication with them and to upgrade the management and the organization of the health service provided. A lot of survey are carry out for this purpose and several questionnaire are built to measure patient satisfaction. 
In particular patient satisfaction is a way to describe and assess the level of hospital service from the patient’s point of view. It is a cognitive and an emotional response to the hospital experience. Methodologically patient satisfaction is defined as a multidimensional latent variable.
To assess patient satisfaction Item Response Theory has greater advantages compared to Classical Test Theory. Rasch model is a one-parameter model which belongs to Item Response Theory. Rasch model yield objective measure
of the construct that are independent of the set of people interviewed and of set of items used. Rasch estimates are continuous and can be useful to “calibrate” the scale of the latent trait.
This research attempt to investigate the questionnaire currently adopted to measure patient satisfaction in an Italian hospital, completed by a large sample
of 3390 patients. We verify the multidimensional nature of the variable, the properties of the instrument and the level of satisfaction in the hospital. Successively we used Rasch estimates to describe the most satisfied and the less satisfied patients.
Spanish and Portuguese hotel corporations on the Northern Littoral of Bahia and the challenges of environmental policies

Year: 2014

description: In light of environmental and territorial policies, this study focuses on the investments in Brazil of Spanish and Portuguese hotel chains, particularly in tourist-residential establishments on the Northern Coast of Bahia. Based on an inquiry conducted among representatives of these corporations, it was observed that the main obstacles faced in their internationalization to this region were administrative red tape, the environmental licensing process and a lack of knowledge of the market. The framework of environmental and urban policies has been the main point of conflict between the companies and the environmental and licensing institutions. The reduced number of skilled technicians capable of assisting the needs of the companies at the state and municipal levels is a crucial factor to explain the delays in the approval of the projects, often causing significant financial damage to the companies, as expressed by their representatives. This study presents a paradigmatic case by which to analyse Brazilian environmental policy, taking into account the on-going process of economic transformation of the country, particularly with regard to its relations with foreign investors.

description: We compute the measure with multiplicity of the set of complex planes intersecting a compact domain in a complex space form. The result is given in terms of the so-called hermitian intrinsic volumes. Moreover, we obtain two different versions for the Gauss-Bonnet-Chern formula in complex space forms. One of them gives the Gauss curvature integral in terms of the Euler characteristic, and some hermitian intrinsic volumes. The other one, which is shorter, involves the measure of complex hyperplanes meeting the domain. As a tool, we obtain variation formulas in integral geometry of complex space forms.

description: The objective of this work was to evaluate the spatial distribution of thermal conditions and bed variables in compost dairy barns with different ventilation systems, through the technique of geostatistics. The experiment was conducted in April 2017, in farms located in Madre de Deus, Minas Gerais, Brazil. Three facilities were evaluated with different ventilation systems: natural (NV); mechanical of low volume and high speed (LVHS); and mechanical of high volume and low speed (HVLS). The interior of the premises was divided into 40 meshes equidistant points, in which air temperature, relative humidity and air speed were manually collected. Geostatistics technique was used to assess the spatial dependence of the variables. The results showed the occurrence of dependence and spatial variability of the variables evaluated. Based on thermal comfort indexes, it was concluded that dairy cows were under stress conditions during the hottest hours of the day in the three animal facilities evaluated. The results obtained allow us to understand that the thermal environment is more influenced by the ventilation system adopted.

description: Problem There has recently been a renewed interest in hemp from the food sector for its contribution to cropping system sustainability and farm economy in semi-arid Mediterranean environments, particularly in organic farming. However, its re-introduction into the Mediterranean environment requires the identification and improvement of cropping practices, particularly in crucial stages such as sowing, harvest and post-harvest. Solution Timely sowings (second half of March and first ten days of April) of suitable varieties on well prepared seedbeds in early spring with rows 18-20 cm apart (a stale seedbed technique is advised), to make use of late winter rains and ensure effective crop germination as well as a rapid soil coverage within 4-5 weeks from sowing.

description: We explore the gravitational instability of clumpy and turbulent gas discs, taking into account the Larson-type scaling laws observed in giant molecular clouds (GMCs) and HI, as well as more general scaling relations. This degree of freedom is of special interest in view of the coming high-z ISM surveys, and is thus potentially important for understanding the dynamical effects of turbulence at all epochs of galaxy evolution. Our analysis shows that turbulence has a deep impact on the gravitational instability of the disc. It excites a rich variety of stability regimes, several of which have no classical counterpart. Among other diagnostics, we provide two useful tools for observers and simulators: (1) the stability map of turbulence, which illustrates our stability scenario and relates it to the phenomenology of interstellar turbulence: GMC/HI observations, simulations and models; (2) a Toomre-like stability criterion, $Q\geq\bar{Q}$, which applies to a large class of clumpy/turbulent discs. We make specific predictions about GMC and cold-HI turbulence, and point out the implications of our analysis for high-z galaxy surveys.

description: A simple protocol which takes advantage of the inherent random times of detections in single photon counting modules is presented for random active basis choices when using entanglement-based protocols for Quantum Key Distribution (QKD). It may also be applicable to the BB84 protocol in certain cases. The scheme presented uses the single photon detectors already present on a QKD setup, working on the same rate as the system is capable of detecting, and is, therefore, not limited by the output rates of quantum random number generators. This protocol only requires small hardware modifications making it an attractive solution. We perform a proof-of-principle experiment employing a spontaneous parametric down-conversion process in a $χ^{(2)}$ non-linear crystal to demonstrate the feasibility of our scheme, and show that the generated sequence passes randomness tests.

Subjects: SolACEPA

description: Problema: La aplicación de fertilizantes de nitrógeno (N) por encima de las necesidades de los cultivos es una práctica agrícola común para garantizar la máxima producción. Sin embargo, suele ocasionar un coste adicional a los agricultores y un aumento del riesgo ambiental debido a las pérdidas de N. Solución: Los sensores ópticos pueden detectar el estado nutricional de los cultivos antes de que las deficiencias graves de nutrientes limiten su crecimiento. Además, permiten ajustar la dosis y el momento de fertilización para cumplir con las necesidades del cultivo. Este método ha sido desarrollado para varios cultivos (p. ej., trigo, maíz y patata) y bajo diversas condiciones ambientales. Los sensores ópticos se pueden comprar o alquilar para realizar medidas (Figura 1), aunque supone un coste adicional para el agricultor, a largo plazo se benefician económicamente por el ahorro de fertilizantes. Para mitigar los efectos de variedades y ambientales, es aconsejable tener una banda de referencia en campo con la dosis recomendada de N. Esto requiere un aporte adicional de N para conseguir la tasa recomendada.

description: We show that in the constant coefficient case the generic tropical variety of a graded ideal exists. This can be seen as the analogon to the existence of the generic initial ideal in Groebner basis theory. We determine the generic tropical variety as a set in general and as a fan for principal ideals and linear ideals.

Down Syndrome: Neuropsychological phenotype and mitochondrial DNA

Subjects: MED/04 Patologia generale

description: Introduction. Down Syndrome (DS) is the most known autosomal trisomy, due to the presence in three copies of chromosome 21. Many studies were designed to identify phenotypic and clinical consequences related to the triple gene dosage. However, the general conclusion is a senescent phenotype; in particular, the most features of physiological aging, such as skin and hair changes, vision and hearing impairments, thyroid dysfunction, Alzheimer-like dementia, congenital heart defects, gastrointestinal malformations, immune system changes, appear in DS earlier than in normal age-matched subjects. The only established risk factor for the DS is advanced maternal age, responsible for changes in the meiosis of oocytes, in particular the meiotic nondisjunction of chromosome 21. In this process mitochondria play an important role since mitochondrial dysfunction, due to a variety of extrinsic and intrinsic influences, can profoundly influence the level of ATP generation in oocytes, required for a correct chromosomal segregation. Aim. The aim of this study is to investigate an integrated set of molecular genetic parameters (sequencing of complete mtDNA, heteroplasmy of the mtDNA control region, genotypes of APOE gene) in order to identify a possible association with the early neurocognitive decline observed in DS. Results. MtDNA point mutations do not accumulate with age in our study sample and do not correlate with early neurocognitive decline of DS subjects. It seems that D-loop heteroplasmy is largely not inherited and tends to accumulate somatically. Furthermore, in our study sample no association of cognitive impairment and ApoE genotype is found. Conclusions. Overall, our data cast some doubts on the involvement of these mutations in the decline of cognitive functions observed in DS.
11 B [i.e. Eleven beta] - Hydroxysteroid NADP Oxidoreductase in mouse foetal tissues

description: Corticosterone in foetal tissues after injection of the mother with ¹⁴C-corticosterone was determined by acetylation. with ³H-acetic anhydride and crystallization to constant specific activity. The corticosterone content of whole foetal tissue varied between gestational days 13 and 17 from 641 to 300 ng/g respectively. The specific activity of foetal hormone recovered remained essentially constant; after a 15-minute pulse this was as much as one-fourth that of maternal hormone. However, placenta, head and liver showed distinctly different patterns of metabolism, which changed greatly during this time in head and liver, with a decrease in the conversion of corticosterone to 11-dehydrocorticosterone and a rise in foetal liver 113-hydroxysteroid:NADP oxidoreductase activity. This mitochondrial enzyme, Km=33yM, pH optimum 6, which reduces the 11-dehydro metabolite to the biologically active 116-OH compound, increased sharply, raising the relative amount of the latter in foetal tissues from 15 to 91% during this period. One day after removal of maternal adrenals, foetal corticosterone was normal and maternal levels close to normal, indicating ability of foetal adrenals to function. Maternal hormone, however, crossed to the foetus readily and it was considered most likely that, normally, the maternal source predominates. Regardless of origin, foetal or maternal, however, the hormone is maintained in different foetal tissues in a distinct and different manner.

Subjects: L-LIN/10 Letteratura inglese

description: La presente tesi si concentra sul romanzo popolare irlandese scritto da donne, nel periodo compreso tra il 1798 e il 1921. Quattro sono le autrici prese in considerazione: Charlotte Elizabeth Tonna, Sydney Owenson (meglio conosciuta come Lady Morgan), Edith Somerville e Katharine Tynan, le cui vite e opere coprono un periodo storico fondamentale per l’uscita dell’Irlanda dal dominio coloniale britannico e la formazione della nazione irlandese nel sud del paese. 
L’interesse principale è quello di analizzare il modo in cui nei loro testi prende forma la nazione, e in particolare attraverso quali immagini e riferimenti religiosi. Il senso è quello, dunque, di rileggere tali testi prestando maggiore attenzione alla religione, uno dei principali collanti tra autrici e pubblico: all’epoca in cui l’Irlanda stava acquisendo i confini che oggi ancora mantiene, esisteva un terreno d’incontro tra discorso politico e letterario, quello della nazione, e tale terreno veniva attraversato anche dal messaggio religioso. 
Il fine ultimo è quello di dimostrare che la letteratura popolare non è “seconda” ad altre quanto a valori che è in grado di trasmettere e a messaggi che è in grado di veicolare: trascurarla significa non capire i meccanismi attraverso i quali una società si sviluppa e si modifica.
description: This research is focused on the Irish popular novel written by women between 1798 and 1921, respectively the year of the Irish Rebellion and that of the Anglo-Irish Treaty, recognizing the Irish Free State as a co-equal dominion of the British Empire. The authors analysed are Charlotte Elizabeth Tonna, Sydney Owenson (better known as Lady Morgan), Edith Somerville and Katharine Tynan, whose lives and works cover a fundamental period in Irish history, inaugurating the withdrawal of Britain from Ireland after eight hundred years, and the formation of an Independent Ireland in the south of the country.
The main interest has been in analyzing the way these four writers write the nation, and through which religious images and references. The attempt is to reread their novels paying particular attention to religion, one of the main tie between author and readers: at the time when Ireland was acquiring the borders today still possess, there existed a common field, that of nation, on which convened politics, literature and religion. 
The aim is to show that popular literature is not secondary to any other narrative for the values and messages it conveys: to ignore it would mean to pay no heed to the devices through which society develops and changes.
