Authors: Andri Setyorini  , Niken Setyaningrum
Published: September 2020

Non-communicable diseases that cause the highest death in the world, one of which is hypertension. In Indonesia, the national prevalence of hypertension in the results of the 2013 Basic Health Research based on the results of blood pressure measurements by medical personnel reached 25.8%. Management of hypertension can be done in two categories, namely non-pharmacological and pharmacological. But in practice it can certainly cause boredom and stress because they have to obey the recommended diet program during his life. So that the portrayal of the patient's implicit beliefs about the illness he is suffering from or called Illness representation can influence the way the patient chooses to deal with his illness including self-management activities carried out by the patient. This study aims to determine the picture related to "Illness Representation in Patients with Hypertension. This study uses a qualitative descriptive approach to data collection using in-depth interviews, participant observation and documentation. Analysis of data using qualitative content analysis. This study produced 6 themes based on the research objectives. The resulting themes are: 1) understanding of hypertension, 2) perceived complaints, 3) causes of disease, 4) duration of illness, 5) complications that may arise, and 6) Control or treatment

SIGNAL PHASE SHIFTS DURING THE MEASUREMENT OF VIBRATION PARAMETERS
Authors: Передерко А.Л., к.т.н.
Published: September 2020

In systems of vibration control, monitoring, diagnostics, active vibration protection, measurements and control of vibration parameters are necessary. For this, piezoelectric sensors are widely used in them as primary transducers. These sensors, due to their high metrological characteristics, such as accuracy, speed, a wide band of operating frequencies and temperatures, are traditionally used to measure vibration displacement, vibration velocity and vibration acceleration. The use of these types of sensors is necessary due to the need to measure and control vibration at objects with different frequency characteristics. The article considers possible distortions of the measured signal at the output of the sensors due to phase shifts. These phase shifts must be taken into account when developing and constructing measurement and processing schemes of the vibration signal. This is especially true when measuring and recording a rapid vibration processes, such as mechanical shock.

Asthma-Allergy Co-morbidity
Authors: Trevor Archer
Published: September 2020

Asthmatic and allergic conditions affect a substantial proportion of individuals globally [1]. They present chronic inhalation and exhalation (breathing) difficulties that arise from inflammatory and spasmodic reactions of the lung's air passages (bronchial tubes/tubules). Notably, risk factors for poor asthma outcomes may have considerable influence on the control level and medical care of asthmatic patients. Most commonly, allergic and asthma are inter-related, sharing several co-morbid conditions, e.g. chronic cardiovascular diseases and metabolic syndrome.
Basic Concepts and Definitions of Allergology
Authors: Vrucinic Zoran
Published: September 2020

The future of medicine belongs to immunology and alergology. I tried to not be too wide in description, but on the other hand to mention the most important concepts of alergology to make access to these diseases more understandable, logical and more useful for our patients, that without complex pathophysiology and mechanism of immune reaction,we gain some basic insight into immunological principles. The name allergy to medicine was introduced by Pirquet in 1906, and is of Greek origin (allos-other + ergon-act; different reaction), essentially representing the reaction of an organism to a substance that has already been in contact with it, and manifested as a specific response thatmanifests as either a heightened reaction, a hypersensitivity, or as a reduced reaction immunity. Synonyms for hypersensitivity are: altered reactivity, reaction, hypersensitivity. The word sensitization comes from the Latin (sensibilitas, atis, f.), which means sensibility,sensitivity, and has retained that meaning in medical vocabulary, while in immunology and allergology this term implies the creation of hypersensitivity to an antigen. Antigen comes from the Greek words, anti-anti + genos-genus, the opposite, anti-substance substance that causes the body to produce antibodies.

Melanosis coli and colon polyps
Authors: Pardillos Tomé A , Guillén Gómez M , Comín Orce A
Published: September 2020

La melanosis coli es una condición benigna, consecuencia del efecto tóxico que producen los laxantes antraquinónicos sobre las células del epitelio colónico, desencadenando apoptosis celular y acúmulo del pigmento lipofucsina en el interior de los macrófagos de la lámina propia. No requiere tratamiento específico y desaparece al retirar el agente responsable. La tasa de detección de adenomas es mayor en estos pacientes debido a una mejor visualización de los pólipos, y no porque exista asociación con mayor riesgo de cáncer colorrectal ni de formación de adenomas.

Published: September 2020

Presentamos el caso clínico a través de imágenes radiológicas e histológicas, de un paciente de 6 años de edad con dolor abdominal persistente, en fosa ilíaca derecha, que fue diagnosticado de apendicitis aguda mediante ecografía. Tras la realización de apendicectomía urgente, durante el acto quirúrgico y en el análisis histológico posterior, se demostró la existencia de un parásito en la luz apendicular, correspondiente a Enterobius vermicularis.

La apendicitis aguda es una de las causas más frecuentes de abdomen agudo, y el tratamiento de elección es la apendicectomía. La propuesta etiológica más aceptada actualmente es la obstrucción del apéndice vermiforme. En un pequeño porcentaje de pacientes estos síntomas apendiculares están motivados por otras causas como la colonización de la luz apendicular por parásitos intestinales, siendo la infección por Enterobius vermicularis la parasitosis con mayor prevalencia en todo el mundo. En estos casos, es fundamental el conocimiento etiológico ya que el tratamiento quirúrgico no será suficiente para su erradicación, siendo necesario complementarlo con fármacos antihelmínticos y medidas higiénicas con objetivo de evitar la progresión y tratar la infección parasitaria larvada.

Apostle Paul's Fundraising Economic Theory of Savings and Social Change
Authors: Shaibu Iddrisu Adam
Published: September 2020

This article critically explores the idea of savings from the New Testament perspective, particularly, using the Pauline fundraising strategy. It argues that the direction given by Apostle Paul regarding the fundraising of the Gentile Christians constitute an informal economic theory of savings. Content analysis was used in reviewing relevant literature for the study. It was established that the directions Paul gave to the Gentile Christians regarding the fund raising constitute informal savings principles. Additionally, Pauline fundraising strategies was eschatological and relational in nature. The paper concludes that Paul’s fundraising was centered on three concepts namely, generosity, gratitude and mission. In this regard, Paul’s fundraising economic theory had the sole aim of bringing social change in the lives of the Jewish Christians.
The Wesleyan Quadrilateral and Contemporary Biblical Exegesis
Authors: Boaheng Isaac
Published: September 2020

How can one discern and apply God’s will and purpose for human life as revealed in
Scriptures? Different scholars have answered this question from different exegetical
perspectives. John Wesley, the founder of Methodism, suggested that any sound biblical
exegesis must have four pillars, namely, Scripture, tradition, reason, and experience. Wesley’s multifaceted approach to biblical exegesis stresses the primacy of Scripture correlated with tradition, reason and experience. This paper explores Wesley’s interpretative framework and deduces lessons from this methodology for contemporary biblical exegetes. In the process, the study points out some flaws in contemporary interpretative practices and suggests how Christians can avoid these flaws.

We report the discovery of a planet in the microlensing event OGLE-2018-BLG-1269 with a planet–host mass ratio q ∼ 6 × 10−4, i.e., 0.6 times smaller than the Jupiter/Sun mass ratio. Combined with the Gaia parallax and proper motion, a strong one-dimensional constraint on the microlens parallax vector allows us to significantly reduce the uncertainties of lens physical parameters. A Bayesian analysis that ignores any information about light from the host yields that the planet is a cold giant

orbiting a Sun-like star

at a distance of

. The projected planet–host separation is

. Using Gaia astrometry, we show that the blended light lies

from the host and therefore must be either the host star or a stellar companion to the host. An isochrone analysis favors the former possibility at >99.6%. The host is therefore a subgiant. For host metallicities in the range of

, the host and planet masses are then in the range of

and

, respectively. Low host metallicities are excluded. The brightness and proximity of the lens make the event a strong candidate for spectroscopic follow-up both to test the microlensing solution and to further characterize the system.
Limits on Protoplanet Growth by Accretion of Small Solids
Authors: Ali-Dib Mohamad , Thompson Christopher
Published: September 2020

This paper identifies constraints on the growth of a small planetary core (0.3 M
⊕) that accretes millimeter-sized pebbles from a gaseous disk. We construct time-dependent spherical envelope models that capture physical processes that are not included in existing global hydrodynamic simulations, including particle size evolution, dust transport, and realistic gas equations of state. We assume a low enough disk density that pebbles are marginally coupled to the gas and are trapped efficiently near the core Bondi radius. Pebbles then drift rapidly enough to experience erosion by sandblasting, mutual collisions, and sublimation of water ice. We find that pebble fragmentation is more efficient than dust resticking. Therefore the high pebble accretion rate

needed to build a core of mass >M
⊕ leads to a high envelope metallicity and grain opacity. Above

yr−1, and without other luminosity sources, convective motions expand near the Bondi radius. The warm, dusty, and turbulent envelope buffers the inward drift of pebble debris: given a turbulent concentration factor f
turb ≳ 1 near the lower convective boundary, the core growth rate is limited to 1 × 10−7
f
turb
M
⊕ yr−1 and the e-folding time 3/f
turb Myr. The remainder of the solid debris is expelled as highly processed silicates. Pebble ice never reaches the core, and the envelope contains comparable amounts of H2/He and metals. We interpret our results using simpler steady models and semianalytical estimates. Future global simulations incorporating the processes modeled here are needed to understand the influence of rotation and vertical disk structure.
On the Approximation of the Black Hole Shadow with a Simple Polar Curve
Authors: Farah Joseph R. , Pesce Dominic W. , Johnson Michael D. , Blackburn Lindy
Published: September 2020

A black hole embedded within a bright, optically thin emitting region imprints a nearly circular “shadow” on its image, corresponding to the observer’s line of sight into the black hole. The shadow boundary depends on the black hole’s mass and spin, providing an observable signature of both properties via high-resolution images. However, standard expressions for the shadow boundary are most naturally parametrized by Boyer–Lindquist radii rather than by image coordinates. We explore simple, approximate parameterizations for the shadow boundary using ellipses and a family of curves known as limaçons. We demonstrate that these curves provide excellent and efficient approximations for all black hole spins and inclinations. In particular, we show that the two parameters of the limaçon naturally account for the three primary shadow deformations resulting from mass and spin: size, displacement, and asymmetry. These curves are convenient for parametric model fitting directly to interferometric data, they reveal the degeneracies expected when estimating black hole properties from images with practical measurement limitations, and they provide a natural framework for parametric tests of the Kerr metric using black hole images.
The Assembly History of M87 through Radial Variations in Chemical Abundances of Its Field Star and Globular Cluster Populations
Authors: Villaume Alexa , Foreman-Mackey Daniel , Romanowsky Aaron J. , Brodie Jean , Strader Jay
Published: September 2020

We present an extensive study of spectroscopically derived chemical abundances for M87 and its globular cluster (GC) system. Using observations from the Mitchell spectrograph at McDonald, LRIS at Keck, and Hectospec on the MMT, we derive new metallicity gradients from ∼2 to 140 kpc. We use a novel hierarchical statistical framework to simultaneously separate the GC system into subpopulations while measuring the metallicity gradients of those subpopulations. We create physically motivated spectral stacks of the GC subpopulations by leveraging the output of this statistical framework to perform the first application of abundance tagging in a massive early-type galaxy to better constrain the origins of the GC subpopulations and thus the assembly history of M87. We find a metal-poor, α-enhanced population of GCs in both the inner and outer halos unanticipated by current cosmological simulations of galaxy evolution. We use the remarkably flat metallicity gradients we find for both the metal-rich and metal-poor GC subpopulations in the inner halo as tentative evidence that some amount of the metal-poor GCs formed directly in the halo of M87 at high redshift.
Simulation of the Interplanetary Bz Using a Data-driven Heliospheric Solar Wind Model
Authors: Li Huichao , Feng Xueshang , Zuo Pingbing , Wei Fengsi
Published: September 2020

Aimed to be ready for the transition from research to operation, we have developed a solar wind model by coupling a data-driven empirical coronal model with a magnetohydrodynamics heliospheric model. We performed a data-driven simulation of the solar wind for a two-year period during the declining and minimum phases of solar cycle 23. Comparisons with OMNI and Ulysses spacecraft data show that the model can reproduce the large-scale variations of the solar wind plasma parameters. The evolution of geocentric solar magnetospheric (GSM) B

x
and B

z
components are also reasonably duplicated by the model in terms of polarity and strength. Apparent signatures of the Russell–McPherron (R-M) effect are found from both observed data and simulated results, indicating that during the investigated interval the R-M effect is the dominant mechanism that controls the large-scale evolution of the north–south component of the interplanetary magnetic field in the GSM frame. The results demonstrate that the established model can provide valuable space weather information about the solar wind.
Inferring Parameters of GW170502: The Loudest Intermediate-mass Black Hole Trigger in LIGO’s O1/O2 data

Published: September 2020

Gravitational wave (GW) measurements provide the most robust constraints of the mass of astrophysical black holes. Using state-of-the-art GW signal models and a unique parameter estimation technique, we infer the source parameters of the loudest marginal trigger, GW170502, found by LIGO from 2015 to 2017. If this trigger is assumed to be a binary black hole merger, we find it corresponds to a total mass in the source frame of

at redshift

. The primary and secondary black hole masses are constrained to

, respectively, with 90% confidence. Across all signal models, we find ≳70% probability for the effective spin parameter χ
eff > 0.1. Furthermore, we find that the inclusion of higher-order modes in the analysis narrows the confidence region for the primary black hole mass by 10%; however, the evidence for these modes in the data remains negligible. The techniques outlined in this study could lead to robust inference of the physical parameters for all intermediate-mass black hole binary candidates (≳100 M
⊙) in the current GW network.
In the Trenches of the Solar–Stellar Connection. I. Ultraviolet and X-Ray Flux–Flux Correlations across the Activity Cycles of the Sun and Alpha Centauri AB
Authors: Ayres Thomas R.
Published: September 2020

This study focuses on high-energy proxies of stellar magnetic activity over long-term starspot cycles of three low-activity Sun-like stars: α Centauri A (HD 128620: G2 V), α Cen B (HD 128621: K1 V), and the Sun itself. Data sets include: daily solar ultraviolet irradiance spectra and X-ray fluxes from the Solar Radiation and Climate Experiment, during recent sunspot Cycles 23 and 24; Interface Region Imaging Spectrograph long-slit stigmatic imaging of solar Mg ii h (2803 Å) and k (2796 Å) in quiet and active regions; and Hubble Space Telescope Imaging Spectrograph ultraviolet, and Chandra X-ray, campaigns on α Cen AB. Established stellar “flux–flux” relations, for example X-rays (T ∼ 1 MK) versus Mg ii (T ∼ 8000 K), showed increasing power-law slopes with increasing formation temperature, but these give way on the Sun to bent power laws, and surprising inversions in the activity hierarchy: Si iii is more “active” (steeper power laws) than N v, despite the latter’s four times higher formation temperature. The Sun’s flux–flux behavior, nevertheless, remarkably parallels its low-activity solar twin α Cen A. In contrast, the cooler, somewhat more active, K dwarf companion displays correlations more in line with the previous stellar paradigm. The new flux–flux relations offer a way to vet numerical spectral simulations and proxy-based irradiance models, and extrapolate solar global activity indices into regimes below or above the grasp of contemporary records, or to exoplanet hosts at the low end of the Sun-like activity ladder.
Advanced Composition Explorer Observations of Turbulence from 1998 through 2002: Data Intervals
Authors: Hamilton Kathleen E. , Smith Charles W. , Vasquez Bernard J. , Leamon Robert J.
Published: September 2020

We have published several papers describing solar wind turbulence at 1 au using data from the Advanced Composition Explorer spacecraft. In an oversight that we regret, we never published the list of data intervals that constitute the database of observations. As we have recently returned to this database of observations in comparisons of turbulent observations by the Voyager spacecraft against established results from 1 au, we wish to now correct our oversight and publish the list of intervals that constitute the 1 au observations. Along with this, we show the distribution of some common solar wind parameters as contained within the database.

Published: September 2020

Atualmente, hortaliças in natura são amplamente recomendadas como parte da alimentação diária. Porém, podem tornar-se potenciais fonte de micro-organismos patogênicos. Este trabalho objetivou avaliar a eficiência de três tipos de sanitizantes na eliminação/redução da carga microbiana de Escherichia coli, coliformes a 35 °C e Staphylococcus aureus em alfaces. Foram utilizados três sanitizantes: hipoclorito de sódio, dicloroisocianurato de sódio e ácido acético. As hortaliças foram distribuídas em três grupos: T0 (grupo controle), T5 e T15 (tratamento com 5 e 15 minutos de imersão nos sanitizantes, respectivamente).  Os resultados mostraram que o tipo de sanitizante e o tempo de tratamento da sanitização apresentaram efeito significativo (p < 0,05) sobre os micro-organismos. O Grupo T0 apresentou os maiores valores de Log de UFC g-1, enquanto que o Grupo T15 apresentou os menores valores. O intervalo de 0 – 15 min de tratamento de sanitização apresentou os maiores números de redução decimal - NRD da carga microbiana para todos os sanitizantes testados, quando comparado com o outro intervalo de tempo 0 – 5 min. Nos dois intervalos de tempos de tratamento, o hipoclorito de sódio foi o sanitizante que mais diminuiu o número de coliformes totais e Staphylococcus aureus. Em contrapartida, o ácido acético foi o que obteve menor eficiência em relação às médias de NRD para os mesmos micro-organismos

Para reduzir as perdas pós-colheita de alguns frutos que são perecíveis e por estarem fora do padrão para comercialização in natura acabam sendo excedentes de safra, surge a produção de bebidas fermentadas como forma de diminuir as perdas durante o processo produtivo. Partindo deste princípio, o trabalho apresentado tem como objetivo estudar a produção de fermentado alcoólico tendo como matéria-prima a polpa da pinha (Annona squamosa L.) que possui propriedades medicinais e nutricionais, bem como seu agradável flavor, evitando o descarte dos frutos que não foram considerados aptos para a comercialização e que são excedentes de colheita. Para tal, após a obtenção da fruta em Alagoas, a polpa desta foi destinada para a fabricação do fermentado levando em consideração técnicas padronizadas no laboratório seguida de análises físico-químicas. Para a produção da bebida fermentada foi utilizado fermento comercial, acompanhando o Brix, pH, acidez, açúcares redutores totais e o teor alcoólico durante o processo. O produto obtido apresentou características que se enquadram nas especificações propostas pela legislação, como a acidez total que promove um maior tempo de conservação e com isso a utilização da pinha na elaboração do fermentado mostrou-se viável por agregar valor à cadeia produtiva assim como visando o aproveitamento de parte dos frutos, como a polpa da pinha, que acabam não sendo comercializados e que são fontes de nutrientes. Por ser um processo tecnicamente simples, este pode ser reproduzido pela população com o intuito de gerar uma renda extra e dar um fim comercial aos excedentes de safra.

O queijo do tipo colonial é caracterizado por ser um produto semigordo, média umidade, maturação curta e de massa semimole. Ainda muito produzido de forma artesanal em regiões ao Sul do Brasil, devido ao clima propício para agropecuária nos meses mais frios. Para que sua produção seja de boa qualidade e seguro para o consumo é necessário controle de qualidade durante todo seu processamento, distribuição e comercialização, começando pela matéria prima (leite) e seu processamento até transformação em queijo. Podendo ocorrer contaminação durante estes processos que leva ao surgimento de Doenças Transmitidas por Alimentos (DTA) ao consumidor. Sendo assim o objetivo deste estudo foi avaliar a qualidade sanitária de queijos colonial comercializados em feiras livres (sem Cadastro Nacional de Pessoa Física) e do comércio varejista (com Cadastro Nacional de Pessoa Física) na cidade de Pelotas-RS. Para isto todas as amostras foram avaliadas quanto a sua adequação sanitária definida pela RDC 12/2001-ANVISA por meio verificação de presença de Salmonella spp., da análise de Coliformes a 45ºC e de Staphylococcus coagulase positiva. De modo geral 83,3% dos queijos com certificação vendidos no comércio varejista estavam seguros para o consumo, e apenas 16,6% dos queijos vendidos em feiras livres sem certificação. A partir de tais resultados verifica-se a necessidade de conscientização dos pequenos produtores, qualificação dos mesmos e vislumbra-se a certificação dos queijos coloniais a fim de revalorizar sua identidade e cultura artesanal. Programas de qualidade e revalorização do produto devem ser incentivados e postos em prática, agregando valor econômico, social e cultural a região produtora.

General aspects of glaucoma: Glaucoma is a heterogeneous multi-factorial disease that is one of the main causes of blindness, along with degeneration of retinal ganglion cells and optic nerve atrophy.

Theories of pathogenesis: There are three theories of glaucoma pathogenesis: biomechanical, vascular, and biochemical.

Basic theory of the glymphatic system: The classical knowledge of cerebrospinal fluid circulation has been revised, and in 2012 a new concept of glial-perivascular – glymphatic perfusion of the brain parenchyma was introduced. Due to experimental and clinical studies, it is approved by many scientists, especially in relation to Alzheimer’s disease (AD), in which amyloid pathology is the result of dysfunction of the para-/perivascular transport/cleansing pathways.

Features of the optic nerve and the cribriform plate: The cribriform plate forms a barrier at the border of intraocular (IOP) and intracranial (ICP) pressures, thus affecting the para-/periarterial flow of cerebrospinal fluid to the optic nerve and retina, as well as the para-/perivenous cleansing outflow.

Morphofunctional evidence of an ocular glymphatic system: The presence of an ocular glymphatic system is con­firmed by in vivo experiments with the transfer of labeled substances through para-/perivascular structures from the ventricular or subarachnoid space to the optic nerve and by postmortem morphology.

Clinical evidence for the glymphatic system hypothesis: There is some clinical, including case-based, and epidemio­logical evidence for similarities between glaucomatous optic nerve/retinal injuries and AD, since both occur in the form of improper secretion of neurotoxic metabolites, and both are often diagnosed together.

Background/Aims: There are few studies describing contemporary status of mechanical ventilation in Korea. We investigated changes in management and outcome of mechanical ventilation in Korea.Methods: International, prospective observational cohort studies have been conducted every 6 years since 1998. Korean intensive care units (ICUs) participated in 2010 and 2016 cohorts. We compared 2016 and 2010 Korean data.Results: Two hundred and twenty-six patients from 18 ICUs and 275 patients from 12 ICUs enrolled in 2016 and 2010, respectively. In 2016 compared to 2010, use of non-invasive ventilation outside ICU increased (10.2% vs. 2.5%, p = 0.001). Pressure-control ventilation was the most common mode in both groups. Initial tidal volume (7.1 mL/kg vs. 7.4 mL/kg, p = 0.372) and positive end-expiratory pressure (6 cmH2O vs. 6 cmH2O, p = 0.141) were similar, but peak pressure (22 cmH2O vs. 24 cmH2O, p = 0.011) was lower in 2016. More patients received sedatives (70.7% vs. 57.0%, p = 0.002) and analgesics (86.5% vs. 51.1%, p < 0.001) in 2016. The awakening (48.4% vs. 31.0%, p = 0.002) was more frequently attempted in 2016. The accidental extubation rate decreased to one tenth of what it was in 2010 (1.1% vs. 10.2%, p < 0.001). The ICU mortality did not change (31.4% 35.6%, p = 0.343) but ICU length of stay showed a decreasing trend (9 days vs. 10 days, p = 0.054) in 2016.Conclusions: There were temporal changes in care of patients on mechanical ventilation including better control of pain and agitation, and active attempt of awakening.

En 1997, le rapport du professeur David Graddol, The future of English, publié par le British Council, ouvrait la voie à diverses études sur le poids des langues dans le monde au présent et au futur. La méthodologie n’était appliquée qu’à l’anglais et la francophonie en particulier était totalement ignorée. Qu’en serait-il aujourd’hui ? C’est à cette question que cette analyse s’efforce de répondre.
Les attentats nous terrorisent-ils ? L’impact des attentats du 13 novembre 2015 sur les préférences des Français
Authors: Bianquis Gaspard , Castell Laura
Published: September 2020

Cet article étudie l’effet causal des attentats du 13 novembre 2015 sur les préférences des Français en matière d’intégration et de dépenses publiques. Les données utilisées sont issues du Baromètre d’opinion de la Drees, collecté du 13 octobre au 1 er  décembre, permettant de traiter les attentats comme une expérience naturelle. Cette évaluation de l’impact des attentats du 13 novembre 2015 montre une forte augmentation de la cohésion sociale perçue par les Français. Les attentats n’ont pas conduit les Français à remettre en cause le système d’intégration préexistant ni la place des questions économiques et sociales dans l’action des pouvoirs publics, mais les ont au contraire conduits à défendre le système existant.

Du vote professionnel à la grève
Authors: Blavier Pierre , Haute Tristan , Penissat Étienne
Published: September 2020

Alors que les pratiques de participation des salariés en entreprise ont souvent été analysées de manière séparée, cet article propose d’investiguer, dans le cas du secteur privé en France, les articulations entre ces pratiques, du vote professionnel à la grève, mais aussi d’en restituer les déterminants et les évolutions récentes en s’appuyant sur les données de l’enquête « Relations professionnelles et négociations d’entreprise » (REPONSE). La majorité des salariés n’est que très peu engagée en entreprise, tandis qu’une minorité y est très engagée. Ces deux pôles renvoient à la conjugaison de deux mécanismes : « l’exclusion de fait », définie comme le fait de ne pas pouvoir participer du fait de l’absence de scrutin ou d’action collective organisée, et « l’auto-exclusion ». La première apparaît fortement dépendante des logiques de fonctionnement du champ économique. En revanche, ce sont surtout les caractéristiques des salariés qui déterminent l’auto-exclusion : les plus précaires et les cadres participent moins, notamment lors des élections professionnelles. Par ailleurs, la participation en entreprise a connu un déclin généralisé depuis le début des années 2000 même si des dynamiques conflictuelles se développent au sein de certaines fractions du salariat.
Les péages dans les Pyrénées françaises (XVIIe-XVIIIe siècles)
Authors: Conchon Anne
Published: September 2020

Tant par le poids de l’histoire que par la présence de la frontière, les Pyrénées présentaient sous l’Ancien Régime une originalité évidente et une indéniable complexité du point de vue de la fiscallité exigible sur les échanges marchands : aux douanes s’ajoutaient les péages perçus sur les routes du piémont comme au cœur du massif montagneux, les leudes du Roussillon et quelques autres impositions locales. Tout au long du XVIIIe siècle, la monarchie va procéder à la vérification de ces droits et s’efforcer de supprimer les perceptions qui ne finançaient pas l’entretien des infrastructures de transport, ou qui pénalisaient l’économie locale comme le commerce transpyrénéen.

Le savoir-faire du fromager, enjeu central pour les filières d’appellation d’origine protégée (AOP), reposerait en grande partie sur « l’œil du fromager », ceci alors que la transformation du lait en fromages se fonde sur un ensemble de processus biochimiques et microbiologiques invisibles à l’œil nu. Dans cet article, nous faisons une proposition théorique visant à enrichir la notion de vision professionnelle développée par Goodwin en anthropologie. En s’inscrivant dans la tradition d’une analyse didactique professionnelle du travail, nous l’articulons à la notion de regard professionnel qui met en évidence la diversité des conceptualisations pragmatiques mobilisées et développées dans les actions de fabrication. Nous étayons notre proposition d’enrichissement à partir de deux terrains d’étude correspondant à deux filières fromagères AOP (Comté et Salers). Nous montrons comment une vision professionnelle débattue se dégage au travers des regards professionnels spécifiques. Ces derniers sont construits non seulement par des environnements sociotechniques, mais aussi selon les buts et stratégies qui engagent les fromagers dans leurs activités de transformation. Nos observations ouvrent alors un questionnement sur l’incidence de l’environnement sociotechnique sur les conditions de transmission/appropriation de « l’œil du fromager »
La fábrica de la mirada

Published: September 2020

Esta introducción al número temático explora el paisaje de la antropología de la mirada mostrando de qué manera se define como una actividad semiológica en el centro de la acción experta profesional. La introducción destaca la originalidad del número: documentar las formas socio-materiales por medio de las que el saber-ver se transmite a los novicios a través del prisma de las profesiones cuyas «maneras de ver» están experimentadas, cuestionadas, reconfiguradas en su fundamento y en sus fronteras. Se tratan aquí algunas temáticas transversales: la construcción del saber-ver, su dimensión multisensorial y multimodal, las metodologías que permiten documentar su aprendizaje y su desarrollo, por último, sus apuntalamientos técnicos y tecnológicos. El objetivo es valorizar la diversidad de los campos de investigación, de las metodologías y de los enfoques propuestos en este número temático que explora el rol de las habilidades visuales en la producción, la circulación y la transformación de las «maneras de ver» en distintas comunidades de práctica.
