Des camps de squatters au nettoyage urbain : processus et enjeux de catégorisation autour du slum à Delhi
Authors: Dupont Véronique
Published: May 2018

À partir de recherches menées à Delhi, cet article propose une réflexion sur les désignations des quartiers d’habitat précaire illégaux – les slums – et les interventions-expulsions qui les visent. Les variations de perception et du vocabulaire autour de l’expulsion reflètent la position du locuteur (urbaniste, magistrat, activiste du droit au logement, habitant), ses registres de référence et la visée de ses discours. La thèse défendue est celle d’un effet de la catégorisation des slums et de leurs habitants sur le traitement qui en est fait. Nous montrons comment des catégorisations majoritairement disqualifiantes sont associées à des mises en accusation de situations irrégulières et de criminalisation, l’ensemble fondant des projets d’intervention. L’examen d’une opération de rénovation en cours dans un quartier précaire permet d’illustrer la manière dont les différents acteurs perçoivent et qualifient une même intervention et de souligner les divergences, y compris parmi les résidents. La partie conclusive replace les démolitions de slums dans le contexte plus large des transformations urbaines et des modes de gouvernance privilégiés.

Estudio de Catulo 5, 7 y 48. El trabajo pretende ante todo mostrar que en estos poemas, como en la mayoría de los catulianos, se pueden reconocer sin dificultad las dos grandes partes en que de ordinario se organiza el epigrama: una primera, más extensa (A), y una final (B), breve, ingeniosa, sentenciosa, que culmina todo lo anterior.
El combate de los trillizos y la imagen de la guerra civil en las Púnicas de Silio Itálico
Authors: Bartolomé Jesús
Published: May 2018

El objetivo de este artículo es estudiar el episodio del combate de los trillizos que Silio Itálico inserta en el relato de la batalla del Tesino (Sil. IV 355- 400). Partiendo del intertexto liviano (Liv. I 25) se analizan las variaciones que el poeta flavio introduce con respecto a su modelo. La narración de Silio acentúa algunas características propias de la guerra civil, pero culmina con el elogio de los combatientes en una clara alusión al apóstrofe dirigido a Euríalo y Niso (Aen. IX 446-449). Esta táctica, aparentemente contradictoria pero totalmente deliberada, contribuye a definir el concepto de épica con respecto a sus predecesores Virgilio y Lucano y sus contemporáneos, especialmente Estacio. Los textos similares que se analizan del autor de la Tebaida así parecen demostrarlo.

Published: May 2018

Breast cancer is one of the main causes of women’s death. Thermal breast imaging is one the non-invasive method for cancer at early stage diagnosis. In contrast to mammography this method is cheap and painless and it can be used during pregnancy while ionized beams are not used. Specialists are seeking new ways to diagnose the cancer in early stages. Segmentation of the breast tissue is one of the most indispensable stages in most of the cancer diagnosis methods. By the advancement of infrared precise cameras, new and fast computers and nouvelle image processing approaches, it is feasible to use thermal imaging for diagnosis of breast cancer at early stages. Since the breast form is different in individuals, image segmentation is a hard task and semi-automatic or manual methods are usual in investigations. In this research the image data base of DMR-IR has been utilized and a now automatic approach has been proposed which does not need learning. Data were included 159 gray images used by dynamic protocol (132 healthy and 27 patients). In this study, by combination of different image processing methods, the segmentation of thermal images of the breast tissues have been completed automatically and results show the proper performance of recommended method.

Published: May 2018

Nickel foam-based Ni-Mo alloy electrodes, Ni+Mo composite electrodes and Ni+Mo/Ni-Mo composite alloy electrodes were prepared by eletrodeposition, and the electrocatalytic characteristics for hydrogen evolution reaction (HER) in 30wt% KOH solution were investigated by cathode polarization curve and electrochemical impedance spectroscopy (EIS). The experimental results show that in comparison with nickel foam electrodes, these electrodes exhibit a lower overpotential, a higher exchange current density and a larger real surface area for HER. At 30°C and current density of 200 mA/cm2, the overpotentials of foam Ni electrodes, nickel foam-based Ni-Mo alloy electrodes, Ni+Mo composite electrodes, Ni+Mo/Ni-Mo electrodes are respectively 506, 252, 336, 202 mV. The nickel foam-based Ni+Mo/Ni-Mo composite alloy electrode had the highest HER electrocatalytic activity.

Authors: Ma Li Li , Xie Qing Lin , Chen Nan Chun , Xu Hui , Zhou Hai Miao , Yu Qing Feng
Published: May 2018

In this study, calcium carbonate was used to coat and link the surface of diatomite for the formation of a novel modified adsorbent (referred to as Ca–diatomite). Various analytical techniques were used to characterize structure and mechanisms of modification and adsorption process, like Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD). Results showed that that Calcium carbonate had been successful grafted onto the surface of diatomite after modification, and Calcium carbonate modification improved the adsorption performance of diatomite for the removal of lead (II) ions from aqueous solution. Ca–diatomite adsorption isotherms and adsorption kinetics were also been studied. The adsorption isotherms and the kinetic data were best fitted with the Langmuir model and pseudo-second-order kinetics, respectively.
Effects of Precipitation of Al3Zr Particles on Microstructures and Properties of the Al-3.55Cu-1.51Li-0.11Zr Alloy
Authors: Jiang Mang , Xu Jin Jun
Published: May 2018

Under single-step and double-step homogenization conditions, the precipitation behavior of Al3Zr dispersoids and its effects on the microstructures and tensile properties of an Al-3.5Cu-1.5Li-0.11Zr alloy were investigated in the current study. It was found that a double-stage homogenization (460 °C/16 h, 520 °C/24 h) enhanced the uniformity of the Al3Zr dispersoids distribution compared with the single-stage homogenized samples. Al3Zr particles which are coherent with the matrix would inhibit the movement of dislocation induced by stress and also the migration of sub-grain boundary and grain boundary induced by thermal activation. The finer particle size and distribution more diffuse of Al3Zr particles reduced recrystallization during hot rolling and solution heat treatment, improving the tensile properties of the as-aged sample.

Published: May 2018

Neutrophils, basophils, and monocytes are continuously produced in bone marrow via myelopoiesis, circulate in blood, and are eventually removed from circulation to maintain homeostasis. To quantitate the kinetics of myeloid cell movement during homeostasis, we applied 5-bromo-2′-deoxyuridine pulse labeling in healthy rhesus macaques (Macaca mulatta) followed by hematology and flow cytometry analyses. Results were applied to a mathematical model, and the blood circulating half-life and daily production, respectively, of each cell type from macaques aged 5–10 y old were calculated for neutrophils (1.63 ± 0.16 d, 1.42 × 109 cells/l/d), basophils (1.78 ± 0.30 d, 5.89 × 106 cells/l/d), and CD14+CD16− classical monocytes (1.01 ± 0.15 d, 3.09 × 108 cells/l/d). Classical monocytes were released into the blood circulation as early as 1 d after dividing, whereas neutrophils remained in bone marrow 4–5 d before being released. Among granulocytes, neutrophils and basophils exhibited distinct kinetics in bone marrow maturation time and blood circulation. With increasing chronological age, there was a significant decrease in daily production of neutrophils and basophils, but the half-life of these granulocytes remained unchanged between 3 and 19 y of age. In contrast, daily production of classical monocytes remained stable through 19 y of age but exhibited a significant decline in half-life. These results demonstrated relatively short half-lives and continuous replenishment of neutrophils, basophils, and classical monocytes during homeostasis in adult rhesus macaques with compensations observed during increasing chronological age.
Coupling between surface ozone and leaf area index in a chemical transport model: Strength of feedback and implications for ozone air quality and vegetation health

Published: May 2018

Abstract. Tropospheric ozone is a significant air pollutant with substantial harm on vegetation, but is also strongly dependent on various vegetation-mediated processes. The interdependence between ozone and vegetation may constitute feedback mechanisms that can alter ozone concentration itself but have not been considered in most studies to date. In this study we examine the importance of biogeochemical coupling between surface ozone and leaf area index (LAI) in shaping ozone air quality and foliage density. We first implement an empirical scheme for ozone damage on vegetation in the Community Land Model (CLM), and simulate the steady-state responses of LAI to long-term exposure to a range of prescribed ozone levels (from 0 ppb to 100 ppb). We find that most plant functional types (PFTs) suffer a substantial decline in LAI as ozone level increases. Based on the CLM-simulated results, we develop and implement in the GEOS-Chem chemical transport model a parameterization that correlates the fractional changes in monthly LAI to local mean ozone levels. By dynamically forcing LAI to respond to ozone concentrations on a monthly timescale, the model simulates ozone-vegetation coupling synchronously via biogeochemical processes including biogenic volatile organic compound (VOC) emissions and dry deposition. We find that ozone-induced damage on LAI can lead to an ozone feedback of −1.8 ppb to +3 ppb in northern summer, with a corresponding ozone feedback factor of −0.1 to +0.6. Significantly higher simulated ozone due to strong positive ozone-LAI feedback is found in most tropical forests, mainly due to the ozone-induced reductions in LAI and dry deposition velocity, whereas reduced isoprene emission plays a lesser role in these low-NOx environments. In high-NOx regions such as eastern US, Europe and China, however, the feedback effect is much weaker and even negative in some regions, reflecting the compensating effects of reduced dry deposition and reduced isoprene emission (which leads to lower ozone in the high-NOx regime). In remote, low-LAI regions including most of the Southern Hemisphere, the ozone feedback is generally slightly negative, likely due to reduced transport of NOx-VOC reaction products that serve as NOx reservoirs. This study represents the first step to account for dynamic ozone-vegetation coupling in a chemical transport model with important ramifications for more realistic assessment of ozone air quality and ecosystem health.
The Ozone Mapping and Profiler Suite (OMPS) Limb Profiler (LP) Version 1 aerosol extinction retrieval algorithm: theoretical basis
Authors: Loughman Robert , Bhartia Pawan K. , Chen Zhong , Xu Philippe , Nyaku Ernest , Taha Ghassan
Published: May 2018

Abstract. The theoretical basis of the Ozone Mapping and Profiler Suite (OMPS) Limb
Profiler (LP) Version 1 aerosol extinction retrieval algorithm is presented.
The algorithm uses an assumed bimodal lognormal aerosol size distribution
to retrieve aerosol extinction profiles at 675 nm from OMPS LP radiance
measurements. A first-guess aerosol extinction profile is updated by
iteration using the Chahine nonlinear relaxation method, based on
comparisons between the measured radiance profile at 675 nm and the radiance
profile calculated by the Gauss–Seidel limb-scattering (GSLS) radiative
transfer model for a spherical-shell atmosphere. This algorithm is discussed
in the context of previous limb-scattering aerosol extinction retrieval
algorithms, and the most significant error sources are enumerated. The
retrieval algorithm is limited primarily by uncertainty about the aerosol
phase function. Horizontal variations in aerosol extinction, which violate
the spherical-shell atmosphere assumed in the version 1 algorithm, may also
limit the quality of the retrieved aerosol extinction profiles significantly.

Published: May 2018

Abstract. Mesospheric airglow measurements of two or three layers were used
to characterize both vertical and horizontal parameters of gravity waves. The
data set was acquired coincidentally from a multi-channel filter (Multi-3)
photometer and an all-sky imager located at São João do Cariri
(7.4∘ S, 36.5∘ W) in the equatorial region from 2001 to
2007. Using a least-square fitting and wavelet analysis technique, the phase
and amplitude of each observed wave were determined, as well as the amplitude
growth. Using the dispersion relation of gravity waves, the vertical and
horizontal wavelengths were estimated and compared to the horizontal
wavelength obtained from the keogram analysis of the images observed by an
all-sky imager. The results show that both horizontal and vertical
wavelengths, obtained from the dispersion relation and keogram analysis,
agree very well for the waves observed on the nights of 14 October and
18 December 2006. The determined parameters showed that the observed wave on
the night of 18 December 2006 had a period of ∼43.8±2.19 min,
with the horizontal wavelength of 235.66 ± 11.78 km having a downward
phase propagation, whereas that of 14 October 2006 propagated with a period
of ∼36.00±1.80 min with a horizontal wavelength of
∼195±9.80 km, and with an upward phase propagation. The
observation of a wave taken by a photometer and an all-sky imager allowed us
to conclude that the same wave could be observed by both instruments,
permitting the investigation of the two-dimensional wave parameter. Keywords. Atmospheric composition and structure (airglow and aurora) – electromagnetics (wave propagation) – history of geophysics (atmospheric sciences)
Integrated management of a Swiss cropland is not sufficient to preserve its soil carbon pool in the long-term

Published: May 2018

Abstract. Croplands are involved in the exchange of carbon dioxide (CO2) between the atmosphere and the biosphere. Further- more, soil carbon (C) stocks play an important role in soil fertility. It is, thus, of great interest to know whether croplands act as a net source or sink of atmospheric CO2, and if soil C stocks are preserved over long timescales. The FLUXNET site CH-Oe2 in Oensingen, Switzerland has been operational since the end of 2003. This cropland is managed under the Swiss framework of the Proof of Ecological Performance (PEP, a variant of integrated management) with a crop rotation centred on winter wheat, which also includes winter barley, winter rapeseed, peas, potato and intermediate cover crops. In addition to eddy covariance measurements, meteorological and soil measurements were available along with information on C imports and exports from organic fertilisation, sowing and harvesting. This study investigates cropland C budgets over 13 years and assesses whether the PEP regulations resulted in a balanced C budget. Strongest CO2 uptake was observed during cereal seasons. C export through harvest, however, offset the strong uptake of the cereal crops. The largest net CO2 emissions to the atmosphere were observed during pea and cover crop seasons. Net biome production, representing the overall C budget, typically ranged between close to C neutral to C losses of up to 407 g C m−2 per season, with peas being the largest source. Overall, the field lost 1674 g C m−2 over thirteen years (129 g C m−2 yr−1), which was confirmed by soil C stock measurements at the beginning and the end of the study period. Although managing the field under the regulations of PEP did not result in an overall C sink, model simulations showed that the use of cover crops reduced the C losses compared to leaving the field bare. The use of solid manure improved the C budget by importing substantial amounts of C into the soil while liquid manure had only a small effect. We thus conclude that additional efforts are needed to bring Swiss management practices closer to the goal of preserving soil C in the long-term.
Obtaining sub-daily new snow density from automated measurements in high mountain regions
Authors: Helfricht Kay , Hartl Lea , Koch Roland , Marty Christoph , Olefs Marc
Published: May 2018

Abstract. The density of new snow is operationally monitored by
meteorological or hydrological services at daily time intervals, or
occasionally measured in local field studies. However, meteorological
conditions and thus settling of the freshly deposited snow rapidly alter the
new snow density until measurement. Physically based snow models and
nowcasting applications make use of hourly weather data to determine the
water equivalent of the snowfall and snow depth. In previous studies, a
number of empirical parameterizations were developed to approximate the new
snow density by meteorological parameters. These parameterizations are
largely based on new snow measurements derived from local in situ
measurements. In this study a data set of automated snow measurements at
four stations located in the European Alps is analysed for several winter
seasons. Hourly new snow densities are calculated from the height of new
snow and the water equivalent of snowfall. Considering the settling of the
new snow and the old snowpack, the average hourly new snow density is
68 kg m−3, with a standard deviation of 9 kg m−3. Seven existing
parameterizations for estimating new snow densities were tested against
these data, and most calculations overestimate the hourly automated
measurements. Two of the tested parameterizations were capable of simulating
low new snow densities observed at sheltered inner-alpine stations. The
observed variability in new snow density from the automated measurements
could not be described with satisfactory statistical significance by any of
the investigated parameterizations. Applying simple linear regressions
between new snow density and wet bulb temperature based on the measurements'
data resulted in significant relationships (r2 > 0.5 and p ≤ 0.05)
for single periods at individual stations only.
Higher new snow density was calculated for the highest elevated and most
wind-exposed station location. Whereas snow measurements using ultrasonic
devices and snow pillows are appropriate for calculating station mean new
snow densities, we recommend instruments with higher accuracy e.g. optical
devices for more reliable investigations of the variability of new snow
densities at sub-daily intervals.
A spatial multicriteria prioritizing approach for geohydrological
risk mitigation planning in small and densely urbanized Mediterranean basins
Authors: Paliaga Guido , Faccini Francesco , Luino Fabio , Turconi Laura
Published: May 2018

Abstract. Landslides and floods, particularly flash floods, occurred currently in many Mediterranean catchments as a consequence of heavy rainfall events, causing damages and sometimes casualties. The high hazard is often associated to intense urbanization in particular along the coastline where streams are habitually culverted. The necessary risk mitigation strategies should be applied at catchment scale, considering the concurrent landslides and flood events and would need to be accurately planned in order to optimize the available economic resources. In the present work 21 small catchments in a high hazard area have been assessed and compared through three sets of parameters: one describing the morphometric-morphological features related to flood and landslide hazard, another describing the degree of urbanization and of anthropogenic modifications at catchment scale and the last related to the elements that are exposed to risk. The aim of the research is to constitute a priority scale among the small catchments, applying the multicriteria analysis technique to the descriptive parameters and giving a support tool for decision makers, supporting a strong scheduling of long-time planning interventions at catchment scale. This approach could be applied in similar context, even at sub-catchment scale, after identifying a suitable set of descriptive parameters depending on the active geomorphological processes and the kind of anthropogenic modification, obtaining the optimization of economic resources.
The Roots of the Contemporary Moravian Church in North America
Authors: Schattschneider David A.
Published: May 2018

Traditionally, the history of the Moravian Church has been divided into two parts: the Ancient Unity (1457–1620) and the Renewed Unity (1722–today). The author suggests a different division for the history of the American Moravian Church: a colonial period (1735–1857) and a contemporary period (1857–today). Scholars and tourists are almost exclusively interested in the colonial period of the Moravians, while Moravian leaders do not value the external perception of the colonial period but rather create an internal perception of the Moravian Church, rejecting the characteristics of the colonial era. The author examines these two interpretations and offers suggestions to reconcile them in the future.
The Textual History of the 1742 Bethlehem Diary
Authors: Peucker Paul
Published: May 2018

Multiple copies exist of the earliest months of the Bethlehem diary, showing substantial differences. These differences were made by editors working on multiple copies on both sides of the Atlantic. Zinzendorf's substantial additions to the diary were taken to Europe in the summer of 1742. The final version Georg Neisser later created in Bethlehem therefore does not include these additions. This research note offers an overview of the different versions and their relationship to each other.

Impacts of Cooperative Thrift and Credit Facilities on Members’ Business Output in Ogun State, Nigeria
Authors: Akerele Ezekiel , Adekunmbi Sheriff
Published: May 2018

Cooperatives play an important role in facilitating access to credit, procurement and storage distribution of input and marketing of products. They create employment opportunities particularly in the rural areas and allow disadvantaged groups to be organized for social and economic benefit. This study was conducted in Abeokuta North and Abeokuta South Local Government Areas of Ogun State, Nigeria. Both primary data and secondary data were used for the study. Multi–stage random sample was used to sample 108 cooperative members. Data collected were analysed using descriptive tools, budgetary analysis, logit and multiple regression model. The findings shows that majority (50.9 percent) of the cooperators are male, 77.8 percent were married,59.3 percent were Christians while 98.1 percent were educated.Majority (87.9 percent) had experience ranging from 1 – 10 which is good in business. The total variables cost from business was estimated at N70,983.47, total fixed cost was N276,271 and this accounted for only 79.56 percent of the total cost. Returns on Investment (RRI), Profitability Index (PI), Return on Variable Cost (RRVC) and Operation Ratio (OR) were 181.62%, 0.63, 173.42% and 0.21 respectively. Also some (48.1 percent) of the respondents enjoyed loan benefit, while 40.7 percent enjoyed business improvement benefit.The results showed that start up capital, labour and credit obtained were significant to cooperative members’access to credit. The result revealed that majority (72.2 percent) of the respondents suffered from non-remittance of deduction by the government as their own challenges. The study concluded that cooperative credit societies is very productive and effective in helping members achieving their goals and also improve their standard of living. Cooperatives societies should encourage members in quick accessibility to loan.

O estudo indica que PMEs, ao elegerem como formadores do valor percebido a experincia e a qualidade, e por serem influenciadas pela satisfao para formar suas intenes de recompras, gerenciam sua cadeia de suprimentos estabelecendo relacionamentos envoltos em mais subjetividades do que se esperaria de um empresrio.Contribuies tericas/metodolgicas: Proposio de um modelo terico capaz de predizer a inteno de recompra de PMEs consumidoras de servios logsticos, tendo como antecessor a satisfao, e desta, o valor percebido.

Activities of Versatile Peroxidase in Cultures of Clonostachys rosea f. catenulata and Clonostachys rosea f. rosea during Biotransformation of Alkali Lignin
Authors: Rybczyńska-Tkaczyk Kamila , Korniłłowicz-Kowalska Teresa
Published: May 2018

The aim of this study was the evaluation of activities of versatile peroxidase (VP) in cultures of Clonostachys sp. (Gliocladium sp.) strains during biotransformation of 0.2% alkali lignin (AL). The principal component analysis (PCA) method was applied to determine the main factors and correlation between biotransformation of 0.2% AL, activity of VPs, pH value, and Clonostachys sp. strains. The biotransformation of 0.2% AL in cultures of microscopic fungi included decolorization (medium lightening) and colorization (darkening of the medium). The versatile peroxidase synthesized by the microscopic fungi tested showed activity for oxidation of Mn(II) and guaiacol, but the activity for oxidation of guaiacol in the presence of Mn(II) was significantly higher. The PCA analysis indicated a strong correlation between biotransformation of 0.2% AL and pH and between oxidation of Mn(II), guaiacol without and in the presence of Mn(II) ions, strains, and pH.
Popular culture as a tool for critical information literacy and social justice education: Hip hop and Get Out on campus
Authors: Smith Kai Alexis
Published: May 2018

We live in a politically polarizing climate and at a time when there is great economic and social unrest in the United States. Our current moment brings to my mind other periods in our nation’s history. First, the 1857 Dred Scott decision, when the Supreme Court decided that slaves were not U.S. citizens and could not sue for their freedom. So that even if a slave escaped to the North, he or she was still considered the property of the slave owner and must be returned.1 The second is in the 1960s, when the antiwar and civil rights movements occurred.2,3

Big impact, small effort: Implementing a low-cost, highly inclusive recognition program with huge results
Authors: Wurm Jill
Published: May 2018

Like many organizations, the Wayne State University Libraries have historically struggled with a recognition system that had the potential to acknowledge people from all areas of the libraries, especially in a way that everyone felt like part of the process. Over the years, we tried things like recognition toolkits for managers, a dedicated recognition team, and formal awards ceremonies, but none were wholly embraced, and they quickly fizzled out as interest waned. Shrinking budgets added to the challenge, as funding for awards became harder and harder to obtain.

Authors: Nicklas Theresa A. , O’Neil Carol E. , Fulgoni  III Victor L.
Published: May 2018

Objectives: The objective of this study was to examine whether there was significant risk associated with types of beverages consumed on the weight status in children.Design: Nationally representative cross-sectional sample.Setting: Demographic information was obtained from the NHANES interviews. Dietary intake data were obtained from Day 1, in-person 24-hour dietary recall interviews administered using an automated multiple-pass method. Height and weight were obtained according to NHANES Anthropometry Procedures Manual.Subjects: Children 2-18 years of age.Results: The likelihood of being overweight or obese was not significant for any of the beverages studied between consumers and non-consumers. For the total sample, for every 29.6 mL of water consumed the risk of being obese was 1%. For ages 6-11 years water consumption increased the risk of being obese and in ages 2-5 years, consumption of sugar sweetened beverages (SSB) increased the risk of being obese. The risk of being obese was significant p <0.05 for Hispanic males for every 29.6 mL of water consumed and for 100% fruit juice and SSB for other males; increased risk was ?3%. The risk of being obese increased for White females for every 29.6 mL of flavored milk consumed and water consumption for both Black females and Hispanic females; the significant p<0.05 increased risk of obesity was ?7%.Conclusions: Beverage consumption was not consistently associated with weight status in the diets of a nationally representative sample of children. In some cases the increased risk was very small.

Authors: Camargo Luiz Octavio de Lima , Cavenaghi Airton José , Pereira Danilo Cava , Wada Elizabeth Kyoko
Published: May 2018

O estudo apresenta os resultados de uma pesquisa empírica na área de hospitalidade e acolhimento que pretendeu traçar um perfil dos participantes de grupos nas redes sociais de fãs do Sesc em São Paulo, centro cultural e de lazer com 41 unidades no estado de São Paulo. A hipótese é a de que este público virtual representa o público prioritário da instituição: o trabalhador do comércio, serviços e turismo, que Prahalad denomina de a base da pirâmide. Para a fundamentação teórica, buscou-se, portanto, em autores de hospitalidade, acolhimento, economia e cultura alguns dos conceitos. Foi elaborado então um questionário com 17 questões – sendo 14 fechadas de múltipla escolha e de mais de uma seleção e 3 abertas -, dividido em três seções: a primeira, que limava quem não participava de nenhum dos grupos do Facebook selecionados; a segunda, para traçar um breve perfil socioeconômico; e a terceira, que procurou entender melhor a assiduidade e participação na programação das unidades do Sesc no estado de São Paulo. A pesquisa ficou disponível de 26 de novembro a 4 de dezembro de 2017, totalizando 224 respostas válidas. De caráter estatístico e exploratório para posterior análise descritiva, o questionário foi aplicado em três grupos de fãs selecionados por número de participantes. Ao final das análises, pôde-se apresentar um breve panorama do perfil do aficionado pelo Sesc, participante de grupos do Facebook, e que percebem as relações de hospitalidade e acolhimento dos funcionários da instituição.
