Historical Changes in Shoreline Position Along the Mississippi Sound Barrier Islands
Authors: Byrnes Mark R. , McBride Randolph A. , Penland Shea , Hiland Matteson W. , Westphal Karen A.
Published: October 2019

A computer-based shoreline mapping methodology, within the framework of a geographic information system, was used to compile and analyze changes in historical shoreline position and island area between 1847/49 and 1986 for the Mississippi Sound barrier island system. The data base consisted of three to four cartographic shorelines and one to two air photo interpreted shorelines. The dominant direction of movement for Dauphin, Petit Bois, Horn, and Ship islands is to the west, whereas cross-shore change in shoreline position is the primary mechanism by which the beaches on Cat Island respond to incident processes. Average shoreline change for the study area was about -1.7 m/yr; however, Horn Island illustrated no net shoreline change for the period of record and the western halves of Petit Bois and Ship islands were net progradational. Although spatial variability in shoreline movement was common, associated land loss was relatively consistent, ranging from -1.6 to -2.5 ha/yr.

The magnitude of lateral island migration is generally an order of magnitude greater than cross-shore movements. East of Dog Keys Pass, the islands are moving to the west by updrift erosion and downdrift accretion at rates exceeding 30 m/yr. The eastern end of Petit Bois Island illustrates the greatest lateral movement, averaging 89.9 m/yr between 1848 and 1986. Long-term changes recorded for the ends of Ship Island are significantly smaller, mainly due to dredging at the Biloxi navigation channel and distance from sand source, limiting the quantity of sand available for natural bypassing to the west. Short-term lateral migration trends illustrate a similar response at Horn Island Pass.
Management Implications of Sediment Dynamics in Delta Marshes of Louisiana
Authors: Cahoon Donald R.
Published: October 2019

Sediment dynamics for the Louisiana coast are reviewed and compared to typical water management schedules for manipulated marsh impoundments to determine the potential for sediment deposition in managed marshes. The opportunity for sediment deposition and the availability of sediment for deposition along the Louisiana coast is greatest for sediment-poor regions during the passage of storms (i.e., cold fronts and tropical storms) and for areas near rivers during spring floods. Manipulated impoundments have been constructed in order to reduce the rate of water exchange between the marsh and adjoining canals as a means to combat the impacts of saltwater intrusion and increased tidal amplitude caused by the extensive network of canals in the coastal zone. The water management schedule (i.e., water flows and water levels) of these impoundments is usually based on the life cycle requirements of those plant and animal species targeted for management and does not necessarily coincide with the times of peak opportunity and availability of sediment for deposition. Hence, the achievement of management goals (e.g., the improvement of waterfowl and wildlife habitat) requires that wetland managers balance the short-term benefits of secondary production and the long-term benefits of sediment deposition in a rapidly subsiding environment. This may result in the manager consciously trading one resource for another, such as sediment and freshwater for low water levels and improved habitat for secondary producers, even in the sediment-rich environs of the Atchafalaya delta region. An evaluation of the trade-offs required by impoundment management and recommendations for maximizing sediment capture in the impoundments are presented.
Late Quaternary Deposition in the Apalachicola Embayment, Northwest Florida Coast
Authors: Donoghue Joseph F.
Published: October 2019

The distribution and composition of the coastal and inner-shelf clastic sediments of northwest Florida have been strongly influenced by the activity of the Apalachicola River. The largest river in the northeastern Gulf of Mexico, the Apalachicola has dominated sedimentation in the region since Neogene time. High-resolution shallow seismic investigations of the inner shelf, combined with coastal borehole records, indicate that the bulk of the clastic sediment cover of the coast and inner margin is late Quaternary in age, and probably Sangamonian or younger. Late Quaternary sea level fluctuations have exerted a major influence on the timing and character of sedimentation in the Apalachicola Embayment.
VELOCITY DEPRESSION AND DEGASIFICATION SUBSIDENCE IN LOUISIANA WETLANDS
Authors: McGinnis Lyle D. , Johnson Donald O. , Zimmerman R. Eric , Isaacson H. Ronald , Penland Shea , Connor Paul E.
Published: October 2019

Modern and ancient delta plains in Louisiana that border the northern Gulf of Mexico are undergoing unprecedented rates of land loss. Subsidence due to compaction and loss of pore water is believed to be one of the primary land loss factors, whereas subsidence due to gas emission is generally believed to play a significant role only in the upper one or two meters of a wetland. Evidence to the contrary is presented here that suggests that degasification subsidence is a more important mechanism contributing to land loss than previously thought. In addition, potential degasification subsidence can be quantified if the depression from normal compressional and shear wave velocities is known. Velocity reductions of 30 to 75% from compressional wave velocity in water and extending to depths of tens of meters have been observed in a saltwater marsh in Louisiana. An order of magnitude reduction in velocity due to the presence of free gas has been observed previously in gas-rich sediments on the adjacent continental shelf, where biogenic gas is observed to depths of 1 km or more. The ratio of normal to depressed compressional wave velocities is used to calculate potential degasification subsidence.
HUMAN IMPACTS ON COASTAL AND ESTUARINE ENVIRONMENTS IN MISSISSIPPI
Authors: Meyer-Arendt Klaus J.
Published: October 2019

Although Mississippi’s toehold on the Gulf of Mexico extends less than 110 km from border to border as the crow flies, human modification of the coastal zone has been extensive. Two of the three major subcomponents of the state’s terrestrial coastal environment–the mainland shoreline, the estuarine embayments, and the barrier islands–have been substantially modified by human activity. Almost half of the 130 km long mainland shoreline has been altered by seawall construction and artificial beach nourishment. The wetland-fringed estuarine embayments of St. Louis Bay and Back Bay of Biloxi became popular loci of recreational development in the boom years of the 1950s and 1960s, and dredge-and-fill activity was widespread. Likewise, industrial development proceeded rapidly during that period, and not until passage of the Mississippi Wetlands Protection Law of 1973 did wetland modification become significantly reduced. Only the barrier islands have escaped extensive human alteration, although development plans have been (and still are) proposed from time to time. The erosion and destruction of the casino resort of Isle of Caprice (presently the Dog Keys shoals) in the 1930s effectively halted offshore resort development plans for several decades, and today three of Mississippi’s four barrier islands are included in the Gulf Islands National Seashore.
HOLOCENE GEOLOGIC FRAMEWORK OF THE TRINITY SHOAL REGION, LOUISIANA CONTINENTAL SHELF
Authors: Pope David L. , Penland Shea , Suter John R. , McBride Randolph A.
Published: October 2019

The geologic framework and sand resources of Trinity Shoal were assessed for their suitability as construction aggregate and beach replenishment material. The study of Trinity Shoal was conducted in two phases. First, potential sand deposits on Louisiana’s continental shelf were identified from published nautical charts and bathymetric maps. A regional seismic survey was then conducted in the area, in which about 800 line-km of high-resolution seismic profiles were acquired and interpreted. The second phase of the study involved acquisition of vibracores. The vibracore locations were chosen from preliminary interpretation of the seismic data, and through analysis of historical and current coastal geomorphology.

From analysis of the seismic and core data, an isopach map, geologic cross-sections, and grain texture analyses were made. Texture, primary physical structures, and sequence associations were used to characterize sediment facies. Six depositional environments were delineated from the core and seismic data. The regressive depositional environments include: (1) prodelta; (2) delta fringe; and (3) distributary channel. The transgressive depositional environments include: (1) lagoon; (2) barrier; and (3) shoal. The shoal environment is represented by the marine sand body that caps Trinity Shoal, and is derived from reworking the underlying barrier facies. In contrast, the barrier environment is comprised of recurved spit, tidal inlet, washover, and sand sheet sub-environments.

Seismic profiles and core logs were integrated to calibrate the seismic facies with shoal and barrier environments interpreted from core analysis. The geologic cross-sections and the isopach map show the shoal and barrier sand thickness trend thinning in a general west to east direction across the study area. Shoal and barrier sand thickness exceed 8 m on the southern or seaward flank of Trinity Shoal. The shoal’s transgressive sand facies offer the best source of material for coastal erosion control projects in terms of volume and quality, with a calculated volume of about 2 billion m3.

An ongoing study utilizes outcrop-scale seismic data and lithofacies data from the Texas continental shelf to develop type sections or preliminary two dimensional depositional models that relate the distribution of sedimentary deposits to sequence stratigraphy. The approach examines the variability in the spatial and temporal distribution of systems tract deposits produced during the most recent glacial-eustatic cycle (the past 120,000 years). The current data base consists of nearly 20,000 kilometers of high-resolution seismic data (with vertical resolution of tens of centimeters to two meters) and lithologic data from hundreds of sediment cores and platform boring descriptions. Only with high resolution data can realistic depositional models be developed.

Detailed work has focused on several study areas (east Texas: Trinity/Sabine, east Texas: Brazos/Colorado, central Texas, and south Texas) that represent a range of depositional settings in terms of sediment supply, shelf gradient, climatic setting, and storm (wave) versus fluvial influence on sedimentation. On the east Texas shelf the transgressive and lowstand systems tracts contain most of the sand-prone deposits. On the central Texas shelf the sand-prone deposits are concentrated in the highstand systems tract. On the south Texas shelf the lowstand and transgressive systems tracts contain sand-prone deposits. Preliminary results suggest that observed trends in the stratigraphic occurrence of sand-prone units repeat themselves during successive glacial-eustatic cycles. This repetition is important because it indicates that these depositional patterns are predictable and therefore can be modeled.
Reservoir Geology Of Incised Valley-Fill Sandstones Of The Pennsylvanian Morrow Formation, Southern Stateline Trend, Colorado And Kansas
Authors: Bowen D.W. , Weimer Paul
Published: October 2019

Incised valley-fill deposits of the Pennsylvanian Morrow Formation of eastern Colorado and western Kansas have proven to be prolific oil reservoirs. Since the discovery of oil from a Morrow sandstone reservoir at Sorrento Field in 1979, 66.5 million barrels of oil have been produced along two major incised valley trends. Ultimate cumulative production from these reservoirs is estimated to be 107 million barrels of oil. Understanding the trapping mechanisms and internal complexities of these reservoirs provides insight to significant opportunities for further exploration and development along these trends and important analog data for similar types of incised valley-fill reservoir plays worldwide.

The Morrow Formation is Early Pennsylvanian in age. Several fourth-order sequences comprise the upper Morrow siliciclastic interval. These high order sequences developed as a result of sea level fluctuations associated with Early Pennsylvanian glacio-eustasy. During the Morrowan, the study area was part of the broad, gently dipping northwest shelf of the Anadarko basin. Rising and falling sea level alternately submerged and exposed this shelf, causing maximum shoreline displacements of 90 to 125 miles (145 to 200 km) across the low-gradient muddy shelf. Extensive drainage systems trending northwest-to-southeast developed during each of these sea level cycles as rivers incised into the muddy shelf strata during lowstand periods. The reservoirs within these valleys are primarily amalgamated fluvial channel sandstones. Marine influenced sandstones are locally important reservoirs that formed from deposition in estuarine systems developed as valleys became flooded from rising sea level. Interfluve areas were sites of soil formation during valley incisement and valley-fill accumulation.

This study focuses on the southern area of the Stateline Morrow trend along the Colorado-Kansas border. Four sequences produce oil and/or gas from incised valley-fill reservoirs in three fields along this trend - Second Wind, Jace, and Moore-Johnson. Establishing the sequence stratigraphic framework for these incised valley-fill sandstones allows for the mapping of trap geometries for petroleum accumulation. The sequence stratigraphic framework is developed by correlating wireline logs and integrating core data. Once the sequence framework is established, individual valley-fill reservoirs can be defined, attributed to specific sequences, and their geometries mapped. Three-dimensional seismic data is of great benefit in determining the dimensions and the geometries of the oldest two valley-fill systems.

Complications to development geology arise when several valley systems of different ages are superposed and cross-cut. Moore-Johnson, Jace, and Second Wind fields illustrate problems with field exploitation due both to superposition of valleys and to internal reservoir complexity resulting from high-frequency relative sea level fluctuations.
APPLICATION OF A NEW HIGH RESOLUTION SEQUENCE STRATIGRAPHY FOR RESERVOIR MODELLING STUDIES OF THE UPPER MIOCENE DELTAIC RESERVOIRS OF THE CHAMPION FIELD, OFFSHORE BRUNEI DARUSSALAM

Published: October 2019

Current completion targets are individual reservoir flow units, often comprising a single depositional unit such as an upper shoreface sandbody or a tidal channel which has remained undrained from previous development campaigns.

Identification, location, and accurate description of these targets requires detailed models of reservoir stratigraphy and architecture, based upon good-quality core and well data sets, together with accurate structural and stratigraphic mapping using high-resolution 3D seismic so that the connected oil in place and transmissivity can be estimated accurately for individual flow units.

The method of ichnofabric analysis, combined with routine sedimentology, provides unequivocal interpretation of shallow marine and estuarine depositional environments allowing the interpreter to recognize and determine the relative importance of the various stratal surfaces seen in cores. The tectonic tilt of the stratal surfaces as interpreted from dip-logs such as the FMI, FMS, or even the SHDT, assists in determining the relative importance of these stratal surfaces.

The key stratal surfaces concept provides the main correlation surfaces (erosional sequence boundaries and flooding surfaces) for delineating individual parasequences, parasequence sets and sequences and for constructing a new high-resolution sequence stratigraphy (HRSS). Once calibrated, these surfaces can be recognized in, and correlated between, uncored wells by the shapes of the natural gamma-ray and density logs. By careful integration of all well data with the high-resolution seismic within the HRSS framework, an accurate description of the geometries and architecture of all the reservoir sediment bodies is obtained.

The final product is a robust and accurate description of the reservoir architecture and facies contents down to the bedset (decimeter) scale. This is a sound basis from which to construct computer-based 3D reservoir models and assign petrophysical properties for reservoir simulation studies.

Shell’s proprietary reservoir modelling software (GEOCAP-MoReS) has been used to provide detailed static 3D reservoir models for reservoir simulation. Results of this work have allowed engineers to optimize field development plans in the mature development phase of field life.
ALLUVIAL FAN/FAN DELTA SEQUENCE STRATIGRAPHY IN A STRUCTURALLY SEGMENTED RIFT BASIN: SIDINGIN FIELD, NORTH AMAN TROUGH, CENTRAL SUMATRA, INDONESIA
Authors: LIRO LOUIS M. , DAWSON WILLIAM C. , YARMANTO
Published: October 2019

The Aman Trough of Central Sumatra, Indonesia has two associated major hydrocarbon accumulations, Minas and Duri fields. As with most maturely explored basins, more recent exploration activities have involved smaller structural closures, often testing new or different exploration concepts. Sidingin Gas Field, discovered in 1989, is located on an isolated fault block on the northern end of the Aman Trough. Wells in the field encountered reservoir stratigraphy quite different from that encountered in most wells in the Aman Trough.

The stratigraphy of the North Aman Trough demonstrates several scales of stratigraphic development: (1) a 2nd order tectonic (syn-rift) cycle, encompassing the entire Pematang Group (Oligocene), composed of stacked fluvial-lacustrine-fluvial members; (2) a series of higher order (3rd order?) sequences, best observed in the fluvial strata, composed of basal coarse fluvial sandstones overlain by floodplain shales; (3) parasequences of individual sandstone/shale couplets.

The fluvial rocks in the North Aman Trough and in the Sidingin field are interpreted in terms of regularly varying and repeating base-level cycles. The sedimentology and stacking patterns can be explained in terms of lowered base-level producing highly erosional coarser-grained fluvial channel sands, likely autocyclic in origin, giving way to individual channel and splay sands deposited as base-level rose, and finally capped by a muddy floodplain shale interval. In many cases, the tops of the shale packages are capped with a paleosol, interpreted as a remnant subaerial exposure surface consistent with a relative lowering of base-level.

Although well logs through Sidingin field display somewhat similar log character to wells within the Aman Trough proper, evaluation of seismic facies and petrography yielded different stratigraphic interpretations. The reservoir in Sidingin field is interpreted as an alluvial fan and fan delta interval, sourced by highlands associated with the rift basin border fault. The facies successions from oxidized, proximal alluvial fan to intercalated fan delta–lacustrine shale strata suggest that base-level variations related to the local structuring controlled stratigraphic development and distribution in the Sidingin field area.
PROXIMAL NONMARINE SEQUENCE STRATIGRAPHY, RESERVOIR QUALITY, AND TECTONIC CONTROLS IN THE SOUTHERN GULF OF THAILAND
Authors: RADOVICH BARBARA J.
Published: October 2019

Texaco Exploration drilled the Mayura #1 well in the southern Pattani Basin of the Gulf of Thailand in the first half of 1994 with partners Fina and Ampolex. The well was drilled on the ramp side of a half-graben and had numerous oil shows in proximal, nonmarine reservoirs within the synrift section. One DST zone flowed oil but the permeability of the reservoir units was compromised by kaolinite in the pore system. High frequency, nonmarine sequence stratigraphy was applied to the wireline log data. Interpretation criteria are outlined suitable for application to proximal stratigraphic positions within alluvial fan to braided plain environments. A typical sequence is composed of stacked, fining-upward parasequence units that aggrade during times of relative base level rise. Each sequence shows the depositional response to factors that reorganize the drainage patterns and/or the delivery system of sediments to the basin. This response records an overall maturing-upward of depositional processes in each sequence through geologic time. Alluvial fan lithologies accumulated near the base of the sequence and braided plain to high energy fluvial sands aggraded in the middle to the top of each sequence. The resulting stratigraphic architecture formed two reservoir plumbing systems that affected the DST results in the Mayura well.

Interpretation of seismic data shows that two large-scale movements on the border fault also affected the sediments in this basin. Tectonically-controlled sediment packages formed with rapid deposition into the accommodation created by slip on the border fault. Poorly organized depositional processes dominated at this time. As the accommodation filled, the fluvial plain broadened and a more mature, fluvial plain had time to develop and aggrade. Tectonic control on the sediments reduced and the influence of other factors, like base level, increased causing a stacked sequence architecture. Each rapid slip on the border fault created a low-order, shallowing-upward sediment package. It is also interpreted to be a ‘maturing-upward’ cycle of depositional processes. The low-order tectonic and higher-order sequence stratigraphy in graben settings show a hierarchy of depositional packages that can lead explorationists to greater predictability of reservoirs within nonmarine environments.

O conceito de Território vem ao longo dos anos passando por diversas definições e conceituações, as quais estão em constante atualização. As instituições escolares, que são um objeto de estudo de diversos trabalhos, se constituem, atualmente, como um importante ator social, visto que além do papel educacional primaz que exerce na educação pode estar sendo um importante instrumento dos interesses econômicos em nossa sociedade. O presente trabalho tem por intuito analisar as instituições escolares pelo viés do conceito de território com base na análise dos ciclos de políticas públicas educacionais de Stephen Ball. As políticas como os currículos, legislações e resoluções balizarão esse elo entre instituições escolares e o conceito de território. O que objetiva entender como as políticas educacionais estão atuando na escola enquanto território. Sendo de grande relevância pois além de contribuir com os estudos pertinentes as questões territoriais, visa também atingir o coletivo docente, visto que este está presente no cotidiano dos territórios escolares e tem a necessidade de entender como as políticas em educação podem influenciar não só o seu trabalho e conteúdos a ministrar mas também toda a comunidade escolar, gestão e seu modo de pensar a educação.Palavras–chave: Território, Rotina Escolar, Estado, Professor, Poder.AbstractThe concept of Territory has over the years gone through various definitions and conceptualizations, which are constantly updated. School institutions, which are an object of study of various works, are nowadays an important social actor since, in addition to the primary educational role that it plays in education, it can be an essential instrument of economic interests in our society. The purpose of this article is to analyze school institutions on the bias of the concept of territory based on the analysis of Stephen Ball 's public policy cycles. Policies such as curricula, legislation and resolutions will link this link between school institutions and the concept of territory. What aims to understand how educational policies are acting in school as a territory. It is of high relevance because in addition to contributing relevant studies to territorial issues, it also aims at reaching the teaching collective, since it is present in the daily life of the school territories and has the need to understand how education policies can influence not only their work and content to minister but also the entire school community, management and their way of thinking education.Keywords: Territory, School Routine, State, Teacher, Power.
Terra e trabalho nos corredores de desenvolvimento: entre o Maranhão (Brasil) e Nacala (Moçambique)

Temos o objetivo de refletir acerca da questão agrária relacionada à precarização do trabalho em espaços periféricos de Moçambique e Brasil, especialmente Nacala e Maranhão, respectivamente, em que grandes projetos de desenvolvimento são implantados com o discurso de modernidade e fim da pobreza. Contraditoriamente, a pobreza, o acesso a terras, a migração de pessoas para atuarem em situações de trabalho precário se reproduzem nesses espaços. A construção de corredores logísticos, com a Estrada de Ferro Carajás e o Corredor de Desenvolvimento de Nacala tem acarretado transformações econômicas nas regiões em que se localizam, com mudanças nas matrizes econômicas, mas também, com mudanças na posse do território, fazendo com que comunidades percam suas terras, prolifere a pobreza, produzindo situações de desigualdade e vulnerabilidade. O trabalho precário, o trabalho escravo, o trabalho forçado são consequências dessas situações de vulnerabilidade que contrastam com o discurso de desenvolvimento, sendo, dessa maneira, resultado dessa modernidade trazida com a internacionalização da economia na atual globalização.Palavras–chave: Trabalho, Desenvolvimento, Território, Brasil/MoçambiqueAbstract We aim to reflect on the agrarian issue related to the precariousness of work in peripheral areas of Mozambique and Brazil, especially Nacala and Maranhão, respectively, in which large development projects are implanted with the discourse of modernity and end of poverty. In contrast, poverty, access to land, migration of people to work in situations of precarious work are reproduced in these spaces. The construction of logistics corridors, with the Carajás Railroad and the Nacala Development Corridor, have led to economic transformations in the regions where they are located, with changes in the economic matrixes, but also with changes in the territory's ownership, causing communities lose their land, create poverty, and produce situations of inequality and vulnerability. Precarious work, slave labour, and forced labour are consequences of these situations of vulnerability that contrast with the discourse of development, being, in this way, the result of this modernity brought with the internationalisation of the economy in the current globalisation.Keywords: Work, Development, Territory, Brazil/Mozambique.
Conceptual Analysis in the Philosophy of Science
Authors: Zach Martin ,   Bulgarian Academy of Sciences
Published: October 2019

Conceptual analysis as a method of inquiry has long enjoyed popularity in analytic philosophy, including the philosophy of science. In this article I offer a perspective on the ways in which the method of conceptual analysis has been used, and distinguish two broad kinds, namely philosophical and empirical conceptual analysis. In so doing I outline a historical trend in which non-naturalized approaches to conceptual analysis are being replaced by a variety of naturalized approaches. I outline the basic characteristics of these approaches with illustrative examples, arguing that recent developments in the philosophy of science show that in order to achieve a more adequate understanding of scientific endeavour we need to prioritize the naturalized accounts of the method.
Notes on the expressive status of photography
Authors: Popescu Costin ,   Bulgarian Academy of Sciences
Published: October 2019

With a history spanning almost two centuries, during which technological advancements on the one hand, and the fluidity of social life on the other, have constantly posed new challenges, photography keeps redefining its place among visual artifacts, and its functions among self-regulatory societal mechanisms.As a widespread practice, photography has generated analyses and commentaries from many theorists of various fields, as well as from more than a few working photographers. Arguments and judgments on the status of photography with regard to its expressive possibilities, adhere to vastly different and often divergent points of view, and most importantly, raise considerable difficulties that prevent these discussions from relying on any methodological coherence.The present text presents some of these arguments and judgments. It aims to provide grounds for more orderly future debates on the artistic quality of photography and especially on the methods of investigating photographic artifacts.
Interpreting The Concept Of Politics In Terms Of Prefixation
Authors: Zhurbina Irina ,   Bulgarian Academy of Sciences
Published: October 2019

The article analyzes the revision of the concept of politics caused by the exhaustion of the ideological paradigm. In modern philosophy politics acquires new meanings through prefixing, resulting in the emergence of such concepts as archi-politics, para-politics, ultra-politics, trans-politics, or bio-politics. These new concepts close the philosophical source of politics laid by the Greek tradition. The departure from philosophy as the source of politics is completed with the idea of police, in which prefixing as a way of conceptualizing politics reaches the linguistic limit. However, modern philosophy encompasses a more positive attitude, which is linked to the hermeneutic tradition of philosophizing of Heidegger and Gadamer that focuses on the preservation of thought and language in the source of political existence.
Distributing Welfare and Resources
Authors: Hupfer Elizabeth C. ,   Philosophy Documentation Center
Published: October 2019

Should theories of distribution focus solely on subjective welfare or solely on objective resources? While both of these ‘currencies’ have well-known objections that make each of them implausible alone, I argue that neither currency should be jettisoned entirely. Instead, I construct a multi-currency distributive theory involving both welfare and resources. While I think that such a heterogeneous theory is able to mitigate objections to both pure resourcism and pure welfarism, it also creates a new concern, which I call the precedence concern, in which a theorist must determine which currency takes precedence in a given situation. I argue that to answer the precedence concern, altering the currency should result in altering the site of distribution as well. As a result, moral value between individuals should be measured in terms of welfare while state justice should be measured in terms of resources.
Interação mãe bebê com deficiência: um estudo de revisão
Authors: Pederro Mariana De Freitas Pereira , Rodrigues Olga Maria Piazentin Rolim
Published: October 2019

Ao nascer, o bebê e a mãe passam por um processo de adaptação, que requer adequações na rotina. A interação mãe-bebê é importante para a qualidade do desenvolvimento infantil. Entretanto, ela pode ser prejudicada quando a mãe não consegue se adaptar às exigências da nova condição que, em geral, exige outras organizações e rotinas mais elaboradas. O objetivo do presente estudo foi analisar artigos que abordam a interação mãe-bebê com deficiência. A busca de artigos foi realizada nas bases de dados online Pubmed, Scielo, Capes, Google Acadêmico, BVS e Parthernon. Foram selecionados 28 artigos, dos quais 71,44% eram internacionais, prevalecendo a publicação em revistas de Fonoaudiologia. Como objetivo os artigos: compararam a interação mãe bebê com e sem deficiência auditiva; analisaram o comportamento interativo materno; identificaram os fatores de risco para a interação; relacionaram a interação mãe-bebê com o desenvolvimento infantil e testaram a confiabilidade de protocolos que codificam a interação. Dos artigos, 35,71% avaliaram uma a 15 díades, 53,57% eram com crianças de 0 a 2 anos e, em 85,71% as mães eram as participantes. Quanto ao delineamento, prevaleceram estudos comparativos (46,38%), o procedimento mais utilizado foi a filmagem (85,71%), com duração de 16 a 30 minutos (60%), realizando de dois a cinco episódios (40%) e as atividades mais frequentes foram alimentação, higiene, leitura de livros e jogos. Sugere-se que novos estudos abordem a presente temática, a fim de auxiliarem no desenvolvimento de intervenções na interação mãe-bebê com deficiência.

Esse texto tem como objetivo discutir a forma como a ciência pós-normal e a interdisciplinaridade podem indicar caminhos para a reflexão cientifica acerca dos danos causados pela indústria de confecções de Maringá. O texto está dividido em três partes, inicialmente apresento o conceito de sociedade de risco de Beck, em seguida aponto a problemática dos resíduos sólidos da confecção no município de Maringá. Finalmente assinalo a importância da ciência pós-normal e da interdisciplinaridade como caminhos que podem contribuir no desenvolvimento e compreensão da complexidade desta questão. Os resíduos sólidos da indústria da confecção precisam ser observados sob diversos pontos de vista, considerando o meio ambiente por meio da sustentabilidade, as normativas legais por meio do governo e o ponto de vista do empresário. Não basta apenas a atuação do governo, mas uma participação mais ampla por parte dos empresários e mesmo da comunidade envolvida com essa problemática, portanto a interdisciplinaridade e a ciência pós-normal mostram-se ferramentas importantes que auxiliam na compreensão das variáveis que fazem parte dessa problemática.
L’exemple du CETA pour les rapports futurs Union européenne / Royaume-Uni – et le report du CETA ?
Authors: Neuwahl Nanette
Published: October 2019

Le Comprehensive Economic and Trade Agreement (CETA, soit l’Accord économique et commercial global entre l’Union européenne et le Canada) est un modèle utile pour les relations commerciales entre l’Union européenne (UE) et le Royaume-Uni après le retrait de ce pays du marché commun. Durant la phase de transition – s’il y en a une –, mais encore plus en absence d’un tel arrangement, les deux parties négociantes feraient bien de travailler à une entente basée sur tel accord commercial, qu’on pourrait provisoirement appeler CC-CETA (Cross-Channel CETA). Un accord inspiré du CETA, possiblement élargi avec d’autres secteurs, tels les services, apporterait des avantages distincts au Royaume-Uni et à l’UE, en remplacement partiel des relations du marché unique. Après avoir examiné d’autres options qui seraient également envisageables, des recommandations pour la conclusion d’un tel CC-CETA sont faites. La question de savoir comment le CETA lui-même pourrait être affecté par le Brexit ou par la conclusion d’un accord UE-Royaume-Uni, ainsi que l’effet préemptif d’un tel accord sur les relations entre le Canada et le Royaume-Uni sont également pris en considération. Finalement, le report du CETA pourrait aussi paraître une solution temporaire pour « assouplir » un Brexit trop dur. Toutefois, cette dernière option est pleine d’incertitudes et mérite d’être accompagné de mesures spécifiques pour certains secteurs.
La place déclinante de la critique dans la sociologie de l’école au Québec ? Hypothèses et pistes de réflexion
Authors: Maroy Christian
Published: October 2019

Cet essai réflexif se propose de comprendre le recul relatif de la dimension critique au sein de la sociologie de l’éducation au Québec. En nous basant sur trois acceptions (épistémologique, rationnelle et sociale) de la critique, nous avançons trois hypothèses. La première hypothèse souligne la complexification et la fragmentation de la base normative de la critique des politiques et pratiques d’enseignement. Elle ne s’appuie plus seulement sur un idéal de démocratisation sociale, mais, parfois de façon ambigüe ou contradictoire, sur une pluralité de référents comme la subjectivation, la reconnaissance des différences culturelles, l’égalité des genres, mais aussi l’efficacité. Il en ressort une transformation mais aussi un affaiblissement de la critique sociale. La seconde hypothèse souligne combien la base épistémologique et rationnelle de la critique est fragilisée par l’évolution du contexte institutionnel dans lequel s’élabore la sociologie de l’éducation (inscription dans les facultés professionnelles ; articulation accrue entre recherche et commande sociale). Enfin, il y a un découplage entre une critique profane et une critique savante de l’école.

Za razliku od prethodnih tehnika, ultrazvučna dijagnostikane uključuje jonizujuće zračenje, nema potrebe za sedacijom pacijenata te omogućujedinamičku analizu peristaltike gastrointestinalnog trakta. Ultrazvučna dijagnostika ješiroko dostupna, neinvanzivna, bezbolna i relativno jednostavno se može izvesti i kodpedijatrijskih pacijenata koji trpe velike bolove. Kod svih gore navedenih oboljenja svakokašnjenje u donošenju tačne dijagnoze može dovesti do neželjenog povećanja morbiditeta,pa čak i pojave mortaliteta. U radu je analizirana uloga ultrazvuka u dijagnosticiapendicitisa, intususcepcije i stenoze pilorusa kod pedijatrijskih pacijenata, ukazano jena ključne ultrazvučne znakove ovih oboljenja te opisana druga normalna i patološkastanja koja pri ultrazvučnom pregledu mogu da imitiraju ova oboljenja.

Medial and lateral hypothalamic loci are known to suppress and enhance appetite, respectively, but the dynamics and functional significance of their interaction have yet to be explored. Here we report that, in larval zebrafish, primarily serotonergic neurons of the ventromedial caudal hypothalamus (cH) become increasingly active during food deprivation, whereas activity in the lateral hypothalamus (LH) is reduced. Exposure to food sensory and consummatory cues reverses the activity patterns of these two nuclei, consistent with their representation of opposing internal hunger states. Baseline activity is restored as food-deprived animals return to satiety via voracious feeding. The antagonistic relationship and functional importance of cH and LH activity patterns were confirmed by targeted stimulation and ablation of cH neurons. Collectively, the data allow us to propose a model in which these hypothalamic nuclei regulate different phases of hunger and satiety and coordinate energy balance via antagonistic control of distinct behavioral outputs.

The grid cell network in the medial entorhinal cortex (MEC) has been subject to thorough testing and analysis, and many theories for their formation have been suggested. To test some of these theories, we re-analyzed data from Bonnevie et al., 2013, in which the hippocampus was inactivated and grid cells were recorded in the rat MEC. We investigated whether the firing associations of grid cells depend on hippocampal inputs. Specifically, we examined temporal and spatial correlations in the firing times of simultaneously recorded grid cells before and during hippocampal inactivation. Our analysis revealed evidence of network coherence in grid cells even in the absence of hippocampal input to the MEC, both in regular grid cells and in those that became head-direction cells after hippocampal inactivation. This favors models, which suggest that phase relations between grid cells in the MEC are dependent on intrinsic connectivity within the MEC.
Targeting the vascular-specific phosphatase PTPRB protects against retinal ganglion cell loss in a pre-clinical model of glaucoma

Elevated intraocular pressure (IOP) due to insufficient aqueous humor outflow through the trabecular meshwork and Schlemm’s canal (SC) is the most important risk factor for glaucoma, a leading cause of blindness worldwide. We previously reported loss of function mutations in the receptor tyrosine kinase TEK or its ligand ANGPT1 cause primary congenital glaucoma in humans and mice due to failure of SC development. Here, we describe a novel approach to enhance canal formation in these animals by deleting a single allele of the gene encoding the phosphatase PTPRB during development. Compared to Tek haploinsufficient mice, which exhibit elevated IOP and loss of retinal ganglion cells, Tek+/-;Ptprb+/- mice have elevated TEK phosphorylation, which allows normal SC development and prevents ocular hypertension and RGC loss. These studies provide evidence that PTPRB is an important regulator of TEK signaling in the aqueous humor outflow pathway and identify a new therapeutic target for treatment of glaucoma.
Cytoplasmic retention and degradation of a mitotic inducer enable plant infection by a pathogenic fungus

In the fungus Ustilago maydis, sexual pheromones elicit mating resulting in an infective filament able to infect corn plants. Along this process a G2 cell cycle arrest is mandatory. Such as cell cycle arrest is initiated upon the pheromone recognition in each mating partner, and sustained once cell fusion occurred until the fungus enter the plant tissue. We describe that the initial cell cycle arrest resulted from inhibition of the nuclear transport of the mitotic inducer Cdc25 by targeting its importin, Kap123. Near cell fusion to take place, the increase on pheromone signaling promotes Cdc25 degradation, which seems to be important to ensure the maintenance of the G2 cell cycle arrest to lead the formation of the infective filament. This way, premating cell cycle arrest is linked to the subsequent steps required for establishment of the infection. Disabling this connection resulted in the inability of fungal cells to infect plants.

Recent studies have identified a genetic variant rs641738 near two genes encoding membrane bound O-acyltransferase domain-containing 7 (MBOAT7) and transmembrane channel-like 4 (TMC4) that associate with increased risk of non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related cirrhosis, and liver fibrosis in those infected with viral hepatitis (Buch et al., 2015; Mancina et al., 2016; Luukkonen et al., 2016; Thabet et al., 2016; Viitasalo et al., 2016; Krawczyk et al., 2017; Thabet et al., 2017). Based on hepatic expression quantitative trait loci analysis, it has been suggested that MBOAT7 loss of function promotes liver disease progression (Buch et al., 2015; Mancina et al., 2016; Luukkonen et al., 2016; Thabet et al., 2016; Viitasalo et al., 2016; Krawczyk et al., 2017; Thabet et al., 2017), but this has never been formally tested. Here we show that Mboat7 loss, but not Tmc4, in mice is sufficient to promote the progression of NAFLD in the setting of high fat diet. Mboat7 loss of function is associated with accumulation of its substrate lysophosphatidylinositol (LPI) lipids, and direct administration of LPI promotes hepatic inflammatory and fibrotic transcriptional changes in an Mboat7-dependent manner. These studies reveal a novel role for MBOAT7-driven acylation of LPI lipids in suppressing the progression of NAFLD.

The main principles of occupational and general public exposure to electromagnetic field (EMF) in the Russian Federation have been presented. EMF hygienic standardization in Russia is based on the results of complex hygienic, clinical, physiological, epidemiological and experimental studies with peer-reviewed data. The concept of threshold principle of occupational and environmental factors exposure hazard effects is the basis of EMF permissible levels substantiation. The data of experimental studies allow the receipt of EMF hazard effects threshold levels. The main criteria of EMF exposure hazard effects in evaluation of experimental study data are the determination of long-term exposure effect threshold levels as well as acute exposure effects. Dose (and time-dependence) approach, which is included in hygienic regulation, allows specifying the value of EMF permissible levels depending on time (exposure duration). This approach is realized in occupational hygienic standards by introduction of “power exposition” and “maximal permissible level” terms, and in general public EMF hygienic standards by permissible levels dependence on the possible duration of exposure.
