An examination of the organizational impact of business intelligence and big data based on management theory
Authors: Alnoukari Mouhib
Published: December 2020

Big data and big data analytics have been considered to be a disruptive technology that will rebuild business intelligence. The purpose of this study is to enrich the literature on the organizational impact of business intelligence and big data based on management theory. While the majority of the organizational theories have had research dedicated to enhance the understanding of the impact of business intelligence and big data on organizational performance and decision-making, the research lacks scholarly work capable of identifying the other main organizational outcomes. To achieve this goal, a semi-systematic literature review was carried out to find all studies related to the research topic. Then, an analysis was conducted to understand the use of the organizational theory in accordance with business intelligence and big data. Finally, a grouping was developed to assign each organizational theory the related impact. The main findings of this work, after examining thirty-three related organizational theories, was that there are other important organizational impacts including innovation, agility, adoption, and supply-chain support.
The linkage between competitive intelligence and competitive advantage in emerging market business: A case in the commercial vehicle industry
Authors: Zwerenz Stefan
Published: December 2020

To achieve competitive advantage (CA) in emerging markets (EM) firms are suggested to increase market orientation, using competitive intelligence (CI) as a source to increase firm performance. However, in-depth linkage between CA and CI, as well as its awareness/culture and process/structure constructs, has been researched and understood only in a limited way in general and for EM business in particular. This paper gives in-depth clarification of six research questions relating to the connection between CI, its constructs and CA for EM business as well as how CI as a product/process could be adapted for a larger impact on CA. It reports on a qualitative, document and interview data based in-depth single case study at a CI department of a European Union (EU) commercial vehicle manufacturer engaging in EM business. It finds that overall the linkage of CI for CA was traceable and transparent to users/generators of CI in the specific case with ambiguously perceived limitations, and influenced by seven identified factors. Seven out of eight pre-identified CI constructs were promoted but also heterogeneously understood as contributing to CA, with no other relevant constructs identifiable. Adaptions for more impact on CA were recommended for CI as a product in a limited sense, and as a process with eight potential levers more comprehensively. These results help businesses to improve CI, its constructs, its products and process for a better linkage to CA and firm performance.

Estudio de las decoraciones murales ocultas del Teatro Italia, en Gualeguay (Entre Ríos, Argentina)
Authors: Gómez Paredes María Alejandra , Alberto Saulino Daniel
Published: December 2020

El objetivo de este trabajo es estudiar las decoraciones murales de la sala del Teatro Italia. Partiendo de diversas hipótesis que formulan la existencia de antiguos diseños bajo los sencillos y despojados recubrimientos modernos que hoy se pueden observar y aplicando diversas metodologías de procesamiento y análisis de imágenes, pudimos confirmar dichos indicios. Los resultados nos permitieron desarrollar una reconstrucción digital virtual de alguno de los posibles momentos históricos-estéticos. Mediante esta técnica pudimos interpretar el aspecto de este bien cultural, de manera virtual y anticipada, en vista de una eventual propuesta de restauración. Cabe señalar que estos estudios forman parte de un proyecto mayor, todavía en curso, que investiga cinco teatros líricos argentinos y sus contextos, articulados en torno al eje fluvial del río Paraná. Ese proyecto, abordado desde diversas dimensiones materiales y simbólicas, pretende reunir un conjunto de instrumentos analíticos para la preservación, conservación y restauración de los mismos.
La otra lista del Patrimonio Mundial. El cambio cultural
Authors: Ruiz de Lacanal Mª Dolores
Published: December 2020

Se trata de un artículo de opinión sobre aspectos teóricos de la Conservación del Patrimonio Cultural, concretamente sobre conceptos y términos. El artículo parte de un concepto bien conocido como es la Lista del Patrimonio Mundial realizada por la UNESCO con el fin de proteger aquellos lugares que tienen un valor universal excepcional, lugares con historia y/o dignos de ser conservados por su extraordinaria belleza. Tomando como referencia esta lista, el artículo plantea y propone hacer otra o completarla de manera que comprenda los lugares del planeta donde existe un vacío cultural, lugares donde la cultura y la identidad cultural están siendo destruidas o lugares donde se manifiesta claramente la pérdida de valores humanos y culturales.Se revisará el concepto de lugares de la memoria desarrollado por Pierre Nora y los lugares que se quieren olvidar de Pierre Vidal-Naquet. Se presentarán las ideas de Maurice Halbwachs y Marc Augé sobre los lugares de la memoria colectiva y los no-lugares y finalmente se recurrirá a los conceptos de humanidad, destrucción y barbarie abordados por notables filósofos y pensadores del siglo XX y XXI como el español José Ortega y Gasset y el francés Tzvetan Todorov. El artículo se realiza desde la conciencia de que el hombre y el patrimonio cultural se encuentran en peligro por distintas causas en diferentes partes del planeta. Se reconoce que los niveles de protección nacional e internacional no son suficientes y que junto a la lista de los lugares de interés cultural, podemos hacer otro mapa del mundo con los lugares que sufren los efectos del cambio cultural.

Authors: Díaz Cortés Andrea , Ramírez Barat Blanca , Leal  Perez-Chao Joaquina , Llorente Irene , Del Egido Marian , Cano Emilio
Published: December 2020

La correcta identificación de los materiales que conforman los bienes muebles del patrimonio científico-técnico y de las interacciones entre los mismos es necesaria para establecer estrategias de conservación eficaces con criterios de intervención adaptados. En este trabajo se presenta un estudio del estado de conservación, materiales y patologías de la colección de extintores del Museo Nacional de Ciencia y Tecnología. Se ha realizado una base de datos con 56 extintores, documentando cada pieza, tipología y estado de conservación. Los análisis realizados en varias de ellas (por fluorescencia de rayos X y difracción de rayos X) han permitido identificar los materiales de los extintores, en algunos casos del contenido de los mismos, y establecer mecanismos de degradación. En el caso de los extintores de espuma y de agua, se ha mostrado que el agente extintor es altamente corrosivo y ha causado daños severos a la pieza. En estos casos, resulta aconsejable eliminar el contenido si se quiere asegurar una correcta conservación de los extintores.
Material characterization and restoration of mural paintings of El-Muzzawaka Tombs, Dakhla Oases, Egypt
Authors: Ali Mona , Shawki Hanaa , Marey Mahmoud Hussein
Published: December 2020

The present study demonstrates scientific procedures applied to study mural paintings in two Graeco-Roman tombs of El-Muzzawaka, Dakhla Oases, Egypt. First, a series of analytical methods was applied to determine the chemical and mineralogical composition of pigment and plaster samples collected from the studied tombs. The analyses were performed by means of digitalized optical microscopy (OM), polarized light microscopy (PLM), scanning electron microscopy attached with X-ray microanalysis detector (SEM−EDS), X−ray diffraction analysis (XRD), and Fourier transform infrared spectroscopy (FT−IR). Analyses of the pigment samples revealed Egyptian blue, Egyptian green, green earth, black magnetite, and red/yellow ochres. The paintings were applied on a coarse plaster layer made of gypsum, anhydrite, calcite, and quartz. The preparation layer was made of two phases of calcium sulphate (gypsum and anhydrite). Further, the detection of an organic binder, of gum Arabic, confirms the application of tempera technique. The results showed that the bed rock samples contain variable amounts of quartz, anhydrite, montmorillonite, kaolinite, gypsum, and sodium chloride (halite). In situ observations showed several deterioration forms on the studied mural paintings. The destructive climatic condition of the region and the defects of the rock structure have contributed seriously in the deterioration process. Based on experimental tests, multi restoration procedures were applied in form of cleaning, reattaching paint flakes, applying injection grouts to detached layers, reconstruction of missing parts in the plaster, repair of wide-open cracks, and final protective consolidation of the painted surfaces. Further, recommendations to minimize any future damage were discussed.
The retouching in Maria Lai’s outdoor artworks: documenting Ulassai’s open-air museum
Authors: Salis Rita
Published: December 2020

From 1981 to 2009, Maria Lai created a series of site-specific outdoor artworks made of different materials (above all cement, then painted with acrylic colour) located in her hometown Ulassai (Sardinia), which became an open-air museum. This paper focuses on a project regarding each artwork, with the creation of a documentation record on their history and conservation issues. Over the years, retouching and repainting interventions were realized by the artist and local workers without any conservator-restorer being involved in the process. The paper also aims to provide a description of these interventions with a focus on three case-studies, exploring the challenges related to maintenance, particularly the ones involving retouching and repainting.

Así, en base a los datos obtenidos mediante estos análisis y junto a cuestiones de ética sobre el tratamiento de las lagunas, se ha desarrollado una metodología de reintegración para los 14 lienzos, pudiendo servir como referencia para otros casos de características similares.
Filling and retouching of losses in a Portuguese Army model 1859 clothes backpack
Authors: Fernandes André , Bailão Ana
Published: December 2020

Two identical backpacks were treated on two occasions to be exhibited alongside at the Lisbon Military Museum. Although both backpacks are the model 1859, the treatment procedures related to the painted canvas were approached differently. The distortions and losses of canvas on the first treated backpack were easily addressed with an ultrasonic humidifier and the insertion of new canvas. Regarding the surface coating, it was consolidated with BEVA® 371, and the inserted canvas was filled with a pigmented wax paste described in a book from the late 19th century. The second backpack was in far worse condition, which, when compared with archive record, seemed likely that it was exhibited for a long period in a damp environment. There were also traces of an organic coating distinct from the original coating. These conditions resulted in a stiffer backpack, with more losses of canvas and surface coating. As a result, the distortions could not be removed, new fabric could not be properly inserted, and the consolidation of the surface coating had to be addressed in a different way. For these motives, the goal of treatment of the second treated backpack was cut short for a more realistic goal, but resulted in a good outcome, nonetheles.
Mapeamentos com sistemas de informação geográfica (SIG) e seleção de critérios de reintegração cromática: pintura de Adriano de Sousa Lopes como caso de estudo
Authors: Cardeira Liliana Querido , Maria dos Santos Bailão Ana , José Henriques Frederico
Published: December 2020

A reintegração cromática de uma pintura é sempre um desafio para os conservadores-restauradores e a decisão de como reintegrar é geralmente baseada no valor e na função das obras. Porém, a escolha de qual a técnica de reintegração é a mais adequada nem sempre é fácil de se justificar. Para tentar ajudar a dar resposta a esta questão foi utilizado um software de Sistema de Informação Geográfica (SIG), designado de QGIS®. Através da edição vetorial foram efetuados vários mapas temáticos com a finalidade de registar as lacunas que se observavam nas pinturas. A análise efetuada com o auxílio do SIG permitiu fazer a caracterização espacial das lacunas em área, para facilitar a tomada de decisão da técnica de reintegração a ser aplicada. Como caso de estudo utilizou-se uma pintura académica de Adriano de Sousa Lopes (1879-1944). Na reintegração cromática usaram-se três técnicas conhecidas de conservação e restauro: o processo mimético, a selezione cromatica e o pontilhismo.

Bilateral Aid Allocation for International Development: Impact of the Financial Crisis
Authors: Balter Elena , Morozkina Aleksandra
Published: December 2020

This article examines the impact of financial crisis of 2008-2009 on allocation of development aid. Using OECD data on Official Development Assistance (ODA) allocation for international development by key donor countries, authors test three hypotheses: first, general impact of crisis on ODA allocation; second, impact of crisis on three recipient income groups; third, impact of crisis on relative importance of analyzed factors for ODA allocation decisions. The results show that general impact of crisis on ODA volumes was negative, although donors preferred to increase aid to low-income countries. Impact of factors describing economic situation in donor countries (public debt level, government expenditures and donor growth) increased after crisis. Donor countries might make use of these results to increase efficiency of their development assistance strategies, whereas recipient countries may exploit these results in order to attract more external financing for development.
Quand donner la vie rime avec risquer la mort. Spécificités du vécu des femmes ayant eu une hémorragie du post-partum et leurs effets sur le devenir mère
Authors: Courtaux Marie , Gueniche Karinne , Gosme Christelle , Ricbourg Aude , Gayat Étienne , Mebazaa Alexandre , Missonnier Sylvain
Published: December 2020

L’hémorragie du post-partum (HPP) est au carrefour de trois champs cliniques : la périnatalité, la réanimation et les expériences extrêmes du corps. La recherche présentée souligne la singularité du vécu de cet incident obstétrical et témoigne des motifs conscients et inconscients des difficultés des femmes à s’engager dans la rencontre avec leur bébé. Le matériel clinique est issu d’entretiens réalisés dans le cadre d’une étude psychologique prospective unicentrique. Les femmes qui vivent une HPP sont traversées par un ébranlement du sentiment de continuité d’être ; la menace vitale court-circuite, ce faisant, l’accès au maternel. Il y a une impossible simultanéité entre la restauration narcissique post-traumatique et l’investissement objectal du bébé. La capacité des parturientes à pouvoir faire psychiquement l’expérience de cet événement traumatique apparaît comme le garant d’une véritable rencontre avec leur bébé et de l’accès au devenir mère. L’entourage et les professionnels de santé semblent déterminants dans le travail de reconstruction psychosomatique qui suit cette expérience extrême.
Somatiser puis se représenter : la fonction de la somatisation dans le traitement psychique des vécus traumatiques chez des adolescents mineurs isolés étrangers
Authors: Guinche Antonin , Feldman Marion
Published: December 2020

Nombre de mineurs isolés étrangers pris en charge sur le territoire français présentent des tableaux multiples et complexes de troubles psychosomatiques. Quels sont alors les rôles de ces troubles ? Cet article propose comme hypothèse que la somatisation accompagne le processus de traitement psychique de traumatismes cumulatifs vécus par des mineurs isolés étrangers. Il l’aborde dans un continuum en proposant la somatisation conséquente d’un clivage post-traumatique comme moyen de liquidation des excitations, comme support d’une douleur désaffectivée prenant lieu et place d’un souvenir insupportable, mais aussi comme béquille au processus de subjectivation. Il s’ancre dans l’abord théorico-clinique de trois situations d’adolescents rencontrés sur le camp de Calais et en foyer de l’Aide sociale à l’enfance. Il élabore également des réflexions sur la prise en charge des mineurs isolés étrangers, rappelant la nécessité de considérer le rôle de la narrativité, mais aussi la dimension de la sexualité dans une clinique où se mêlent traumatisme, deuils, culture et adolescence. Il vise ainsi à enrichir la réflexion sur cette clinique très actuelle.
Climat et économie au début du XIV e siècle : la crise agraire de 1314-1322 en Bresse d’après les comptes de châtellenie
Authors: Labbé Thomas
Published: December 2020

La crise agraire de 1314-1322 est considérée comme le symptôme visible de la récession économique qui frappe l’Occident à partir de la fin du xiii e  siècle. Caractérisée par deux chocs céréaliers, l’un en 1315-1317 qui a conduit au développement dans l’Europe du Nord-Ouest de la plus grave famine de son histoire, et l’autre en 1321-1322 qui voit les prix atteindre des records, elle fait l’objet depuis quelques années d’un renouveau historiographique par l’histoire environnementale. Dans le contexte des questionnements relatifs à l’impact du changement climatique, les progrès réalisés dans le domaine de la reconstruction du climat ont en effet permis de montrer que cette crise éclate pendant une période de transition climatique rapide, marquée par une très forte variabilité interannuelle, séparant l’Anomalie climatique médiévale du Petit Âge glaciaire. Les caractéristiques économiques de cette crise sont à l’heure actuelle essentiellement connues à travers l’exemple du sud de l’Angleterre, dont les archives manoriales permettent une reconstitution minutieuse des prix, des rendements, et des stratégies d’adaptation adoptées par les communautés rurales face à ces difficultés. Cet article a pour but d’éclairer cette période révélatrice des liens climat-société à partir d’un terrain inédit, dont les archives comptables permettent de telles reconstructions : la Bresse savoyarde. On montre que la conjoncture y évolue parallèlement à ce qui a été reconstruit pour l’Angleterre, et que l’impact du climat a produit des effets similaires, quoique de moindre intensité. On montre également le processus de vulnérabilisation progressif de ces communautés rurales face au stress climatique, phénomène aggravé par leurs propres stratégies d’adaptation. De sorte qu’une crise sociale, marquée par un appauvrissement massif, culmine dans les années 1320.
Effect of Insertion Torque on Bone Screw Pullout Strength
Authors: Lawson Kevin Jon , Brems John
Published: December 2020

ABSTRACT

The effect of insertion torque on the holding strength of 4.5-mm ASIF/AO cortical bone screws was studied in vitro. Screw holding strength was determined using an lnstron materials testing machine (Bristol, United Kingdom) on 55 lamb femora and 30 human tibiocortical bone sections. Holding strength was defined as tensile stress at pullout with rapid loading to construct failure. Different insertion torques were tested, normalizing to the thickness of cortical bone specimen engaged. These represented low, intermediate, high, and thread-damaging insertion torque. All screws inserted with thread-damaging torque and single cortex engaging screws inserted to high torque tightening moments showed diminished holding strength. This loss of strength amounted to 40%-50% less than screws inserted with less torque.

As data-driven learning has been advancing across new frontiers in recent years, there is still a paucity of studies on data-driven vocabulary learning model that brings about effectiveness in teaching and learning practices. Idiomaticity, which serves as an important indicator for language proficiency, needs abundant contextualized language input for the acquisition of target words. In this regard, the present study explores whether computer-assisted language learning is effective in vocabulary acquisition, and in the differentiation of synonymous words on the part of learners. Pre-/posttests and questionnaires were administered among an experimental group (N=26) and a control group (N=26). Results showed that the experimental group, who was instructed under the data-driven learning model, got a higher mean score than the control group, who received traditional dictionary-consulting instruction. The former also finished the posttest within a much shorter period of time. A significant relationship was found between the pretest scores and posttest scores among the experimental group whereas the scores in the control group did not reach statistical significance. Therefore, there was a significant improvement in learners’ performance on collocation production under the data-driven learning model, whilst dictionaries did not prove to have such a contributing effect. This study provides some suggestions for how to enhance learners’ idiomaticity by improving collocation performance under the data-driven model.

The possibility of both energy and environmental crisis that may arise due to use of fossil fuels has resulted in intense research activities in the past decade on the development of technologies for harvesting and storage of energy from renewable sources. In order to meet the energy requirements for an ever-increasing population, there is a need for high performance electrochemical energy harvesting as well as storage devices. Nanomaterials and nanocomposites with diverse composition, structure, and morphologies have been applied in various energy related applications ranging from photocatalytic hydrogen generation, solar electricity generation, electric energy storage by lithium ion batteries and supercapacitors, hydrogen storage systems, etc. The aim of this chapter is to provide an overview of the recent developments in the technological advancements brought about by the use of nanotechnology in energy harvesting and storage appliances with specific focus on dye sensitized solar cells for electricity generation, lithium ion batteries, and supercapacitors for energy storage.
Harnessing the Versatility of Invariant NKT Cells in a Stepwise Approach to Sepsis Immunotherapy

Sepsis results from a heavy-handed response to infection that may culminate in organ failure and death. Many patients who survive acute sepsis become immunosuppressed and succumb to opportunistic infections. Therefore, to be successful, sepsis immunotherapies must target both the initial and the protracted phase of the syndrome to relieve early immunopathology and late immunosuppression, respectively. Invariant NKT (iNKT) cells are attractive therapeutic targets in sepsis. However, repeated treatments with α-galactosylceramide, the prototypic glycolipid ligand of iNKT cells, result in anergy. We designed a double-hit treatment that allows iNKT cells to escape anergy and exert beneficial effects in biphasic sepsis. We tested the efficacy of this approach in the sublethal cecal ligation and puncture mouse model, which mirrors polymicrobial sepsis with progression to an immunosuppressed state. Septic mice were treated with [(C2S, 3S, 4R)-1-O-(α-d-galactopyranosyl)-N-tetracosanoyl-2-amino-1,3,4-nonanetriol] (OCH), a TH2-polarizing iNKT cell agonist, before they received α-galactosylceramide. This regimen reduced the morbidity and mortality of cecal ligation and puncture, induced a transient but robust IFN-γ burst within a proinflammatory cytokine/chemokine landscape, transactivated NK cells, increased MHC class II expression on macrophages, and restored delayed-type hypersensitivity to a model hapten, consistent with recovery of immunocompetence in protracted sepsis. Structurally distinct TH2-polarizing agonists varied in their ability to replace OCH as the initial hit, with their lipid chain length being a determinant of efficacy. The proposed approach effectively exploits iNKT cells’ versatility in biphasic sepsis and may have translational potentials in the development of new therapies.
Cerebral infarction in a child with congenital adrenal hyperplasia presenting as acute encephalitis syndrome

Congenital Adrenal Hyperplasia (CAH) is an inherited abnormality of steroid synthesis. It is usually diagnosed in the early neonatal period. Its association with white matter abnormalities in the developing brain has been reported. Cerebral infarction is one of the rarely associated complications of classical CAH. A 5-year-old child had presented with features of acute onset fever, refractory new-onset seizure, and altered sensorium. He was a known case of CAH, on regular exogenous steroid supplementation. Investigations revealed that he had extensive hemorrhagic cerebral infarction. No underlying infective or vascular cause could be detected to explain the etiology of cerebral infarction in this child. Hence, the effect of CAH on the developing brain and an inadequate escalation of steroid dose during stress have led to the cerebral infarction.
An explicit construction of the universal division ring of fractions of $E\langle\langle x_1,\ldots, x_d\rangle \rangle$
Authors: Jaikin-Zapirain Andrei
Published: December 2020

We give a sufficient and necessary condition for a regular Sylvester matrix rank function on a ring

R

to be equal to its inner rank

\rho_R

. We apply it in two different contexts.

In our first application, we reprove a recent result of T. Mai, R. Speicher and S. Yin: if

X_1,\ldots, X_d

are operators in a finite von Neumann algebra

\mathcal M

with a faithful normal trace

\tau

, then they generate the free division ring on

X_1,\ldots, X_d

in the algebra of unbounded operators affiliated to

\mathcal M

if and only if the space of tuples

(T_1,\ldots, T_d)

of finite rank operators on

L^2(\mathcal M,\tau)

satisfying [ \sum_{i=1}^d [T_k,X_k]=0, ] is trivial.

In our second and main application we construct explicitly the universal division ring of fractions of

E\langle\langle x_1,\ldots, x_n\rangle\rangle

, where

E

is a division ring, and we use it in order to show the following instance of pro-

p

Lück approximation.

Let

F

be a finitely generated free pro

p

-group,

F=F_1 > F_2 > \cdots

a chain of normal open subgroups of

F

with trivial intersection and

A

a matrix over

\mathbb F_p [[F]]

. Denote by

A_i

the matrix over

\mathbb F_p[F/F_i]

obtained from the matrix

A

by applying the natural homomorphism

\mathbb F_p [[F]] \to \mathbb F_p[F/F_i]

. Then there exists the limit [ \displaystyle \lim_{i\to \infty} \frac{\mathrm {rk}_{\mathbb F_p} (A_i)}{|F:F_i|} ] and it is equal to the inner rank

\rho_{\mathbb F_p [[F]]}(A)

of the matrix

The Growth and Survival of Carpet Clam, Ruditapes decussatus in Çardak Estuary (Çanakkale Strait, Northwest Turkey)
Authors: ERDAL Hakan , ÖNAL Umur
Published: December 2020

The growth and survival potential of the carpet clam, Ruditapes decussatus, in Çardak estuary (Northwest Turkey) were investigated. Clams were grown in 3 different locations with different substrate characteristics. Results indicated that clams grown in larger size substrate (Station C) composed of 38.41% cobble, 21.90% pebble and 17.16% granule by weight had higher growth and survival compared to those grown in substrates composed of smaller size fractions. Clams planted with a mean length and wet weight of 2.772 cm and 4.032 g, reached a mean length and wet weight of 3.614 cm and 9.179 g at the end of 10 months. Transportation before planting had considerable effect on clam survival. In addition, mortality rates during summer were considerably higher in all stations than other seasons. Although the mean growth and survival rates of clams observed were similar to previously reported values, high summer mortality remains to be the most important factor for further investigations.
Cryptanalysis of LowMC instances using single plaintext/ciphertext pair

Published: December 2020

Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned with the actual use case of this cipher in PICNIC signature scheme. Due to the design paradigm of PICNIC, an adversary trying to perform a forgery attack on the signature scheme instantiated with LowMC would have access to only a single given plaintext/ciphertext pair, i.e. an adversary would only be able to perform attacks with data complexity 1 in a known-plaintext attack scenario. This restriction makes it impossible to employ classical cryptanalysis methodologies such as differential and linear cryptanalysis. In this paper we introduce two key-recovery attacks, both in known-plaintext model and of data complexity 1 for two variants of LowMC, both instances of the LowMC cryptanalysis challenge.
