Ruralidades, enfoque territorial e políticas públicas diferenciadas para o desenvolvimento rural brasileiro: uma agenda perdida?
Authors: Pereira Leite Sergio
Published: January 2020

This paper invites a reflection on “styles” or “models” of development that have characterized social, economic and politico-institutional transformations in rural areas. It does so by evaluating territorial development, differentiated public policies, and the emergence of new ruralities in the agricultural context in Brazil, based on the experience over the last few decades. By drawing on international literature, this work assesses the meaning of the use of new ruralities to characterise farming environments, and its impact over important indicators and governmental policies. With a focus on Brazil, the article traces recent processes that help to sketch out possible “snapshots” of the national agricultural landscape, as evidenced in work based on land grabbing and financialization of land, and on the constitution of rural territories. These processes are supported by important governmental policies, such as rural credit and territorial development programs. The recent crisis of agricultural policies in Brazil brings new challenges in terms of understanding this broader context, and raises new questions, which will be addressed in the concluding remarks. Keywords: rural development; territorial development; agricultural policies; ruralities.LEITE, Sergio Pereira.

The paper presents the outcomes of a field research on food practices of selected agricultural families in the region of Chapecó (SC), emphasizing the combination between preservation of old and introduction of new eating habits and their main determinants, in a context of narrow urban-rural links. It also analyzes the degree of diversity of diets and sources of food based on extensive data collection, and interviewed families' perceptions of their food and nutrition security. Among the findings of the research we highlight significant changes in the eating habits of the interviewed agricultural families, high degree of diversity of diets, importance of urban-rural links, especially of intra-family ties in relation to the phenomenon of multi-locational families.Keywords: food practices; eating habits; agricultural families; food and nutrition security.MALUF, Renato Sérgio; ZIMMERMANN, Silvia Aparecida.

As práticas produtivas e alimentares no espaço rural do Oeste de Santa Catarina: a ação pública na busca e na crítica à modernidade
Authors: Grisa Catia , Tecchio Andréia , Chechi Leticia Andrea , Eric Sabourin
Published: January 2020

The western region of Santa Catarina was integrated to the “modernization of agriculture” in the 1950s, through the agro-industrialization of the food system, having as protagonists the State, civil society and the market, which acted at the national, state and municipal levels. Based on the sociology of public action, the objective of this paper is to verify how public policies promoted modernity and how the more recent public actions and policies reinforce or delineate new patterns and trajectories of rural development and influence productive and food consumption practices. The methodological procedures consisted of literature review and field research. In 2018, we conducted 13 semi-structured interviews with public managers and mediators from seven organizations operating in the region, two focus groups and 49 questionnaires with family farmers located in Chapecó and nine adjacent municipalities. The results indicate that modernity has led a significant portion of family farmers to produce less food for self-consumption and to consume more industrialized and ultra-processed foods, besides causing concentration of production, rural exodus and environmental pollution. Faced with these risks and uncertainties, “new” food and production practices emerged, and new actors began to build alternatives to modernity. The “new” production strategies consisted of food agro-industrialization, agroecological production, biodiversity restoration, creation of fairs, and the maintenance of production for self-consumption, supported by various actions and public policies. The same State that produces productive and food risks, threats and uncertainties, also contributes to food and nutritional security in the region.Keywords: public action; modernity; productive and food practices.GRISA, Catia; TECCHIO, Andréia; CHECHI, Leticia Andrea; SABOURIN, Eric.

Conhecimento sobre os conceitos de selos de qualidade vinculados à agricultura familiar
Authors: Groot Etiénne
Published: January 2020

Family farming is challenged by participating in Long Supply Chains. In this context, production processes must be communicated to the market through quality labels. The product’s added value increases when concepts related to the labels are known by consumers. The objective of this work was to evaluate consumers’ knowledge about quality labeling concepts, in Dracena (São Paulo State). For this, 257 personal interviews were conducted with the help of a structured questionnaire, between April and June 2018. The results indicate that 1/3 of consumers are unaware of organic farming and just over half are unaware of family farming concepts. Quilombo and fair-trade products are virtually unknown in Dracena. There was a positive relationship between educational attainment levels and knowledge of family farming and organic products. In conclusion, the work has shown the need for an extensive and continuous consumer information campaign on quality labelling.Keywords: Family Farming Identification Label (Sipaf); Brazilian Quilombo Label; FairTrade Label; Brazil Organic Product Label; Long Supply Chain.GROOT, Etiénne.

Published: January 2020

This article aims to describe the dynamics of community associativity and local rural entrepreneurship policies based on the experience of three associations of the village of Tribunas Córcega in the municipality of Pereira, Colombia for the year 2018. Methodologically, a timeline and a survey of open-ended questions to association leaders were applied. By way of results, diverse associative processes are evident, as well as the execution of policies for rural entrepreneurship in the territory. However, the associations face great internal and external weaknesses that limit their enterprises. At the end it is concluded that there is a multifunctionality consistent with the organizational forms adopted by the communities. In contrast, there is evidence of low access to municipal policies of entrepreneurship and, therefore, some potentials that need to be developed.Keywords: community associativity; rural entrepreneurship; public policy; Colombia.CALDERÓN, Patricia Elena Giraldo; CARDONA, Maicol Lopera; ACEVEDO, Marleny Cardona.

Research on the dating behavior of teens at boarding houses in Ruteng City consists of two parts - research on high school teenagers and college’s students teenagers. This report focuses on the results of research to students living at boarding houses. This study was designed to describe the dating behavior of teenage boarders in the Ruteng, Manggarai Regency. Sexual dating behavior that drives this research is about emerging forms of thinking about sexual drive for couples. Various forms, such as holding hands, hugging, kissing, touching sensitive body parts, and sexual intercourses. Based on this concept, dating behavior is grouped into 4 activities, dating, necking, petting, and intercourses. Getting data, the team used survey by quantitative approach. Data collection techniques consisted of questionnaires, interviews, and observations. Questions related to student dating behaviors. Questionnaire was supported by interview and observation. The total participants were 320 students who were dating in Ruteng. From the total and 95% confidence level, the team determined margin of error totally 5.3%. Data were analyzed by descriptive statistical techniques and non-parametric statistics. Descriptive statistics were used to describe the condition of participants in terms of age, circumstances, and semester level. Non-parametric statistics were used to assess the significance of the relationship between age, circumstances, and semester variables for dating safety. Some of them have even been prominent in sexual relations. These facts were caused by unregulated environments. In Ruteng, the boarding houses do not have a construction permit because they do not have local regulations from the Manggarai regency government. This confirms the owner's mentality that is oriented to money and ignore the rules, do not limit male and female relations of boarders, and the desire of teenagers to make boarding as a safe dating place. The results of this study are expected to be a reference for local governments to issue local regulations.

Published: January 2020

The practice of integrating education with computers has been used worldwide because of the emerging education global trends. Computer literacy in teachers plays an important role in the integration of technology in education, which favours the Kenyan education system. This study set out to determine the teacher computer literacy level in public primary schools Ainamoi Sub-County, Kericho.  A descriptive survey design was used involving 21 headteachers, 42 lower primary teachers, one ICT Expert, and CASO officer. Data were collected using structured interviews, questionnaires, and checklist observation. Purposive, simple random sampling and stratified sampling were used to sample the respondents. Data was presented in tables and percentages. The findings revealed that computer teacher training that was done in May 2015 did not cater for all the teachers in the field. This is because headteachers and only two lower primary teachers were trained from each school. It was also founded that teachers who graduated from teacher training colleges from 2009 were computer literate out of all the teachers employed by the Teachers Service Commission (TSC) after 2006. There is a need for the government to arrange the seminars and in-service programs to cater to those teachers who are already in the field but are computer noncompliant. Teachers should be ready to embrace the new technology and integrate it into teaching and learning. Teachers should have more exposure to computers and ICT facilities to enhance their computer competency. A digital computer content guide should be developed by the Kenya Institute of Curriculum Development to enhance consistent computer knowledge. Besides, teacher training colleges should provide KNEC examinable computer courses.

Published: January 2020

In this study, Chinese yam starch-water suspension (8%) were subjected to high-pressure homogenization (HPH) at 100 MPa for increasing cycle numbers, and its effect of on the physicochemical properties of the starch was investigated. Results of the polarizing microscope observations showed that the starch granules were disrupted (i.e. greater breakdown value) after HPH treatment, followed by a decrease in cross polarization. After three HPH cycles, the crystallinity of starch decreased, while the crystal type remained unaltered. Meanwhile, the contents of rapidly digestible starch and slowly digestible starch were increased. On the contrary, resistant starch content was decreased. Our results indicate that HPH treatment resulted in reduction of starch crystallinity and increase of starch digestibility.

Published: January 2020

Sufu is usually prepared by single-fungus fermentation with Mucor racemosus or Rhizopus oryzae. The quality of sufu fermented by different strains tends to differ. In this study, mixed fermentation (using M. racemosus and R. oryzae) and single-fungus fermentation (using only M. racemosus) were carried out, and the changes in physicochemical properties were assessed and compared. We found that the main enzyme activity of sufu in mixed fermentation was higher than that of M. racemosus fermentation, and the biochemical and texture properties of the sufu produced differed significantly between both fermentation processes. Thus, we demonstrated that mixed fermentation has several advantages over M. racemosus fermentation in terms of biochemical profile and texture of sufu. Our results provide insights for improving the efficiency of the industrial production of sufu, as well as sufu quality.

Cool core galaxy clusters are considered to be dynamically relaxed clusters with regular morphology and highly X-ray luminous central region. However, cool core clusters can also be sites for merging events that exhibit cold fronts in X-ray and minihalos in radio. We present recent radio/X-ray observations of the Phoenix Cluster or South Pole Telescope (SPT)-CL J2344-4243 at the redshift of z = 0.596. Using archival Chandra X-ray observations, we detect spiraling cool gas around the cluster core as well as discover two cold fronts near the core. This is perhaps the most distant galaxy cluster to date known to host cold fronts. Also, we present JVLA8 1.52 GHz observations of the minihalo, previously discovered at 610 MHz with GMRT9 observations in the center of the Phoenix galaxy cluster. The minihalo flux density at 1.52 GHz is 9.65 ± 0.97 mJy with the spectral index between 610 MHz and 1.52 GHz being −0.98 ± 0.16.10 A possible origin of these radio sources is turbulence induced by sloshing of the gas in the cluster core.
Possible Evidence for the Gluon Condensation Effect in Cosmic Positron and Gamma-Ray Spectra

The gluon condensation (GC) effect in cosmic proton–proton collisions at high energy is used to explain an excess in the positron spectrum observed by the Alpha Magnetic Spectrometer. We find that this excess may originate from the GC effect in Tycho's supernova remnant.
IRIS Observations of Short-term Variability in Moss Associated with Transient Hot Coronal Loops
Authors: Testa Paola , Polito Vanessa , Pontieu Bart De
Published: January 2020

We observed rapid variability (≲60 s) at the footpoints of transient, hot (∼8–10 MK) coronal loops in active region cores, with the Interface Region Imaging Spectrograph (IRIS). The high spatial (∼0.″33) and temporal (≲5–10 s) resolution of IRIS is often crucial for the detection of this variability. We show how, in combination with 1D RADYN loop modeling, these IRIS spectral observations of the transition region (TR) and chromosphere provide powerful diagnostics of the properties of coronal heating and energy transport (thermal conduction or nonthermal electrons, NTEs). Our simulations of nanoflare-heated loops indicate that emission in the Mg ii triplet can be used as a sensitive diagnostic for nonthermal particles. In our events, we observe a large variety of IRIS spectral properties (intensity, Doppler shifts, broadening, chromospheric/TR line ratios, Mg ii triplet emission) even for different footpoints of the same coronal events. In several events, we find spectroscopic evidence for NTEs (e.g., TR blueshifts and Mg ii triplet emission), suggesting that particle acceleration can occur even for very small magnetic reconnection events, which are generally below the detection threshold of hard X-ray instruments that provide direct detection of emission of nonthermal particles.
Toward the Detection of Relativistic Image Doubling in Imaging Atmospheric Cherenkov Telescopes
Authors: Nemiroff Robert J. , Kaushal Neerav
Published: January 2020

Cosmic gamma-ray photons incident on the upper atmosphere create air showers that move to the Earth’s surface with superluminal speed, relative to the air. Even though many of these air showers remain superluminal all along their trajectories, the shower’s velocity component toward a single Imaging Atmospheric Cherenkov Telescope (IACT) may drop from superluminal to subluminal. When this happens, an IACT that is able to resolve the air shower both in time and angle should be able to document an unusual optical effect known as relativistic image doubling (RID). The logic of RID is that the shower appears to precede its own Cherenkov radiation when its speed component toward the IACT is superluminal, but appears to trail its own Cherenkov radiation when its speed component toward the IACT is subluminal. The result is that the IACT will see the shower start not at the top of the atmosphere but in the middle—at the point along the shower’s path where its radial velocity component drops to subluminal. Images of the shower would then be seen by the IACT to go both up and down simultaneously. A simple simulation demonstrating this effect is presented. Clear identification of RID would confirm in the atmosphere a novel optical imaging effect caused not by lenses but solely by relativistic kinematics, and may aid in the accuracy of path and speed reconstructions of the relativistic air shower.

Inspired by the discovery of the Phoenix cluster by the South Pole Telescope team, we initiated a search for other massive clusters of galaxies missing from the standard X-ray catalogs. We began by identifying 25 cluster candidates not included in the Meta-Catalog of X-ray Clusters of galaxies cluster compilation through cross-identification of the central galaxies of optically identified clusters in the Sloan Digital Sky Survey GMBCG catalog with bright X-ray sources in the ROSAT Bright Source Catalog. Those candidates were mostly unidentified or previously classified as X-ray active galactic nucleus (AGN). We analyzed brief Chandra X-ray Observatory observations of 14 of these X-ray sources and found that eight are X-ray luminous clusters of galaxies, only one showing evidence for a central X-ray point source. The remaining six candidates turned out to be point-source dominated, with faint detections or upper limits on any extended emission. We were not able to rule out the presence of extended X-ray emission from any of the point sources. The levels of extended emission around the six point sources are consistent with expectations based on optical richness, but could also be contaminated by scattered X-ray light from the central point source or extended nonthermal emission from possible radio lobes. We characterize the extended components of each of the well-detected cluster sources, finding that six of the eight X-ray clusters are consistent with being compact cool-core clusters. One of the newly identified low-luminosity X-ray clusters may have had an X-ray-luminous AGN 20 yr prior to the recent Chandra observations, based on the 4σ difference between its Chandra and ROSAT fluxes.
Hot Subdwarf Stars Identified in Gaia DR2 with Spectra of LAMOST DR6 and DR7. I. Single-lined Spectra

Published: January 2020

182 single-lined hot subdwarf stars are identified by using spectra from the sixth and seventh data releases (DR6 and DR7) of the Large Sky Area Multi-Object Fibre Spectroscopic Telescope survey. We classified all the hot subdwarf stars using a canonical classification scheme, and got 89 sdB, 37 sdOB, 26 sdO, 24 He-sdOB, 3 He-sdO, and 3 He-sdB stars, respectively. Among these stars, 108 hot subdwarfs are newly discovered, while 74 stars were reported by previous catalogs. The atmospheric parameters of these stars were obtained by fitting the hydrogen (H) and helium (He) lines with non-local thermodynamic equilibrium model atmospheres. The atmospheric parameters confirm the two He sequences and the two subgroups of He-sdOB stars in our samples, which were found by previous studies in the T
eff–

diagram. Our results demonstrate different origins of field hot subdwarf stars and extreme horizontal branch stars in globular clusters, and provide strict observational limits on the formation and evolution models of the different sub-types of these evolved objects. Based on the results, we evaluated the completeness of the Geier et al. catalog. We found the fraction of hot subwarf stars is between 10% and 60%, depending on the brightness of the sample. A more accurate estimation for the hot subdwarf fraction can be obtained when similar results from composite spectra will become available.
Effect of Sofosbuvir Administration and Its Withdrawal on the Submandibular Salivary Gland of Adult Male Albino Rats: A Histological and Ultra-Structural Study
Authors: Mahmoud Abdeen Asmaa , Essawy Tarik , Mohammed Saher Sayed
Published: January 2020

BACKGROUND: Sofosbuvir (SOF) was published in 2013 as a part of first-line treatments for hepatitis C virus (HCV); it has activity against all genotypes with extrahepatic adverse effects have recently arisen.
AIM: Investigating sofosbuvir-induced alterations in the rat submandibular salivary gland (SMSG).
METHODS: A group of 80 adult albino rats weighing about Â± 150 gm were used in the experiment. The rats were divided into 3 groups: Group I (control group) received distilled water, Group II (experimental group) divided into 2 subgroups and received SOF 40 mg/kg/day dissolved in distilled water for 1 and 3 months and Group III (recovery group) allowed for 1 month of recovery after SOF withdrawal. All animals were sacrificed; the SMSG was dissected, and specimens were examined histologically and ultra-structurally.
RESULTS: Compared to Group I, Group II subgroup (1) showed acinar and ductal vacuolisation, discontinuity of the epithelial lining associated with retained secretion and congested blood vessels. These changes were found to be exaggerated in the subgroup (2) accompanied by acinar and ductal shrinkage, interstitial oedema, haemorrhage, chronic inflammatory cells infiltration and loss of gland compactness. Amelioration of the histological changes was detected in Group III after SOF withdrawal. The ultrastructural examination confirmed the histological results.
CONCLUSION: SOF had induced apparent alterations in the structure and ultrastructure of SMSG. The SOF-induced alterations were time-dependent, attributed mainly to mitochondrial toxicity and partially ameliorated by its withdrawal.
Eocene “Chusquea” fossil from Patagonia is a conifer, not a bamboo
Authors: Wilf Peter
Published: January 2020

Chusquea oxyphyllaFreng. & Parodi, 1941, a fossilized leafy branch from the early Eocene (52 Ma), late-Gondwanan Laguna del Hunco biota of southern Argentina, is still cited as the oldest potential bamboo fossil and as evidence for a Gondwanan origin of bamboos. On recent examination, the holotype specimen was found to lack any typical bamboo characters such as nodes, sheaths, ligules, pseudopetioles, or parallel leaf venation. Instead, it has decurrent, clasping, univeined, heterofacially twisted leaves with thickened, central-longitudinal bands of presumed transfusion tissue. These and other features allow confident placement in the living Neotropical and West Pacific disjunct genusRetrophyllum(Podocarpaceae), which was recently described from the same fossil site based on abundant, well-preserved material. However, the 1941 fossil holds nomenclatural priority, requiring the new combinationRetrophyllum oxyphyllum(Freng. & Parodi) Wilf,comb. nov.No reliable bamboo fossils remain from Gondwana, and the oldest South American bamboo fossils are Pliocene.Chusqueajoins a growing list of living New World genera that are no longer included in Paleogene Patagonian floras, whose extant relatives are primarily concentrated in Australasia and Malesia via the ancient Gondwanan route through Antarctica.
Hong Kong, une voix démocratique en Chine
Authors: Le Corre Philippe
Published: January 2020

Hong Kong connaît depuis plusieurs mois des manifestations d’hostilité à l’égard du gouvernement chinois. La poussée démocratique ne faiblit pas et pourrait avoir des conséquences politiques lors des élections à venir cette année. Pour comprendre l’évolution de la situation, il faut prendre aussi en compte la recomposition économique de l’ensemble de la région, où Hong Kong n’est plus nécessairement en pointe.
Les alternatives aux abattoirs industriels
Authors: Porcher Jocelyne
Published: January 2020

Les critiques radicales actuellement portées par les théoriciens et par les militants de la « libération animale » à nos relations domestiques avec les animaux visent tout particulièrement l’élevage. Celui-ci serait par essence criminel puisqu’il conduirait nécessairement à l’appropriation, à l’exploitation et à l’abattage des animaux. Or, l’élevage n’a pas le monopole de la mort des animaux domestiques.
La démocratie sans les libertés
Authors: Salas Denis
Published: January 2020

En Europe, ces dernières années, nombre de régimes politiques, une fois installés au pouvoir, ont sacrifié délibérément les libertés. Ce n’est pas la démocratie en tant que telle qui est en cause – tous ces dirigeants étant démocratiquement élus – mais, avant tout, la démocratie libérale. Compte tenu du nombre de pays concernés, il n’est pas excessif de dire que cette dissociation entre démocratie et libéralisme inquiète autant qu’en son temps, la montée du totalitarisme.

Authors: Bigot Raphaëlle , Dallet Néhémie , Rousseau Rosalie
Published: January 2020

Introduction : La barrière linguistique a des effets négatifs sur l’accès et sur la qualité des soins des patients allophones. Devant cette problématique, des dispositifs d’interprétariat professionnel physique et téléphonique en médecine libérale ont été mis en place en 2017 dans la région Pays de la Loire en s’inspirant des projets menés depuis 2010 par l’association Migration Santé Alsace. L’objectif principal de cette étude était d’évaluer la satisfaction des médecins libéraux à l’utilisation de ces dispositifs d’interprétariat en consultation avec leurs patients allophones. Méthode  : Cette étude descriptive quantitative, observationnelle et prospective a été menée dans l’ensemble de la région Pays de la Loire de juin 2017 à décembre 2018. La satisfaction a été évaluée à l’aide d’un questionnaire informatique rempli par les médecins utilisateurs à la fin de chaque consultation avec interprète. Résultats  : Les résultats montrent une très bonne satisfaction globale des médecins à l’utilisation de l’interprétariat professionnel, qu’il soit physique ou téléphonique. L’étude a également permis de mettre en lumière le renforcement de la relation médecin-patient et de l’alliance thérapeutique. Les principaux freins rapportés étaient les contraintes liées au temps, avec notamment un allongement de la durée de la consultation. Discussion : Cette étude souligne l’intérêt majeur du développement et de la pérennisation des dispositifs d’interprétariat en médecine libérale. L’interprétariat professionnel apparaît comme un outil facile d’utilisation ; peu de freins ont été rapportés par les utilisateurs. Il garantit le respect de la personne et de son droit à s’exprimer et à donner son consentement libre et éclairé.

Politics in Christian missions
Authors: Alawode Akinyemi O.
Published: January 2020

For decades, the mobilisation of Christian missions has encountered a number of setbacks and barriers because of several factors and elements that pose severe impediments to the conduct of missionary activities. Amongst these factors and elements, the involvement of politics in the activities of the Christian missions is prominent. The goal of the Christian missions is to expand the kingdom of God, as well as the salvation and restoration of lost souls, while the goal of politics is to secure power and authority through manipulation for selfish interests or gains. A Christian mission seeks spiritual and heavenly fulfilment, while politics seeks mundane and worldly gains.
Gray-level Co-Occurrence Matrix application to Images Processing of crushed Olives fruits.
Authors: Márquez Antonio Jiménez , Beltrán Maza Gabriel
Published: January 2020

This paper shows the results obtained from images processing digitized, taken with a 'smartphone', of 56 samples of crushed olives, using the methodology of the gray-level co-occurrence matrix (GLCM). The values ​​of the appropriate direction (θ) and distance (D) that two pixel with gray tone are neighbourhood, are defined to extract the information of the parameters: Contrast, Correlation, Energy and Homogeneity. The values ​​of these parameters are correlated with several characteristic components of the olives mass: oil content (RGH) and water content (HUM), whose values ​​are in the usual ranges during their processing to obtain virgin olive oil in mills and they contribute to generate different mechanical textures in the mass according to their relationship HUM / RGH. The results indicate the existence of significant correlations of the parameters Contrast, Energy and Homogeneity with the RGH and the HUM, which have allowed to obtain, by means of a multiple linear regression (MLR), mathematical equations that allow to predict both components with a high degree of correlation coefficient, r = 0.861 and r = 0.872 for RGH and HUM respectively. These results suggest the feasibility of textural analysis using GLCM to extract features of interest from digital images of the olives mass, quickly and non-destructively, as an aid in the decision making to optimize the production process of virgin olive oil.
The Chord Index, its Definitions, Applications, and Generalizations
Authors: Cheng Zhiyun
Published: January 2020

In this paper, we study the chord index of virtual knots, which can be thought of as an extension of the chord parity. We show how to use the chord index to enhance the quandle coloring invariants. The notion of indexed quandle is introduced, which generalizes the quandle idea. Some applications of this new invariant is discussed. We also study how to define a generalized chord index via a fixed finite biquandle. Finally, the chord index and its applications in twisted knot theory are discussed.
