Authors: He Yifan , Luo Xianbo , Shi Hongfu
Published: April 2019

Q oilfield is a typical fluvial reservoir, which is located in the middle of Bohai Bay. Lower member of Ming (Nm) formation and upper member of Guantao (Ng) formation of Neogene are the main oil-bearing strata, with buried depth -950m ~ -1430m, and developed fluvial sedimentary sandstone reservoir. The lower member of Minghuazhen formation developed meandering river deposit, and sandbody was mainly composed of complex meandering. Guantao formation developed braided river deposit. Each oil group has a good vertical superposition, which shows high porosity and high permeability (average 3000mD), but the oil viscosity of each oil group is quite different (from 22mPa s~260mPa s).

Offshore wind is a quickly-emerging market resulting from the worldwide transition towards renewable energies. Whilst this transition has countless environmental benefits, the negative aspects pertaining to underwater noise generated during wind park construction are coming under increased public scrutiny. A number of countries have responded to this environmental and social concern by establishing underwater noise regulations. Construction using current piling techniques often requires the use of underwater noise mitigation systems to meet these legislative requirements. These systems can be applied at the piling source, near pile or far from pile. Under the Underwater Noise Abatement System (UNAS) program, partially sponsored by the Dutch government’s ‘Rijksdienst voor Ondernemend Nederland’ (RVO), a new noise mitigation system has been tested. The UNAS consortium consists of three partners: Van Oord Offshore Wind Projects, AdBm Technologies, and TNO (Netherlands Organization for Applied Scientific Research). The noise mitigation system, here after referred to as NMS, consists of a slatted system containing Helmholtz resonators which is deployed around a monopile in a similar method to venetian blinds. Scaled tests of the NMS at Butendiek and Luchterduinen Offshore Wind Parks showed potential for full-scale deployment. The full-scale test of the NMS was executed in the fall of 2018. A configuration where the vertical spacing of the slats was 0.67 m yielded a 7 to 8 dB SEL re 1 μPa2s reduction compared to the unmitigated scenario, while combining the NMS with a big bubble curtain (BBC) resulted in a 14 to 15 dB SEL reduction compared to the unmitigated situation. This reduction range, as well as a smooth offshore operational performance, puts the NMS in line with other near pile mitigation systems. Deployment of the NMS appears a feasible option to ensure underwater noise compliance in various nation’s legislation.
Hydrate Management for Hydrate Deposition in Gas-Filled Vertical Pipes

Published: April 2019

Deadlegs are defined as pipe sections in intermittent use for production or special services in oil/gas production systems. Deadlegs often pose hydrate control challenges to gas and oil production systems as the fluid inside is close to stagnant and therefore can be rapidly cooled by the environment without proper insulation or heat tracing. Water vapor can condense in the deadleg, resulting in a potential hydrate risk. Over time the deadleg may be blocked completely by hydrates. The hydrate challenges, if not properly managed, can cause severe consequences in terms of safety and cost for oil/gas productions. A systematic study has been performed to better understand the process and mechanism of hydrate deposition in deadlegs. To study hydrate deposition in deadlegs experimentally, laboratory scale deadleg systems were designed and built to consider pipe sizes of 1-, 2-, 3-, and 4-in. inner diameter and approximately 50 in. long. The pipes were gas-filled and saturated with water from a reservoir at the bottom of the pipe. The experimental work focused on measuring hydrate deposition, and in some cases, plugging, for different water reservoir temperatures (30 to 80 °C), pipe wall temperatures (-10 to 15 °C), and duration (1 to 84 days). The results from measurements provided insights into the dynamic process of hydrate deposition, such as the mechanism for hydrate deposition, plugging, and distribution along the pipe.
The Subsea Revolution: Execution Excellence Through Standardization
Authors: Gable Brent David , Amadeus Wolfgang
Published: April 2019

A revolutionary application of existing technology, driven by the downturn in the industry, has enabled operators to adopt the high-quality existing standards of service companies instead of implementing project-specific, single-use requirements and documentation. This has created economic viability through total expenditure (totex) reductions as well as early production benefits for operators. This paper showcases how one operator and supplier achieved a 12-month subsea tree delivery while minimizing cost through standardization.

Legacy project execution models make a 12-month subsea tree delivery unachievable while driving up costs through extended alignment phases, large project teams, and procurement of project-specific components. Achieving prealignment through robust documentation, technical workshops, and a unique approach to assessing risk of perceived gaps between organizations has proven successful in the execution of an offshore project in the Caspian Sea and clearly highlights the benefits of standardization.

An enhanced industry-standard offering leads to both competitive and sustainable advantages, ensuring marginal fields are economically viable. The objective of a standard system offering is delivering a subsea production system at maximum capital efficiency and minimal lead time to optimize operators' return on investment while driving industry-leading safety, peak reliability and uptime, and superior quality. The Caspian Sea project execution methodology will discuss the benefits achieved in using standard products in a subsea production system and elaborate on the potential further benefits this approach would have on a larger brownfield application.
Wave Energy Converter Arrays: Optimizing Power Production While Minimizing Environmental Effects
Authors: Raghukumar Kaus , McWilliams Samuel , Chang Grace , Roberts Jesse , Jones Craig
Published: April 2019

The nascent marine renewable energy (MRE) industry requires robust tools to maximize power output while evaluating the potential environmental effects of marine hydrokinetic (MHK) devices. Wave energy converter (WEC) devices in particular, are in early stages of development and may deploy a wide range of technologies to harness wave energy. The technical activities and processes used to assess WEC arrays for both power production and environmental effects requires streamlining to lower the levelized cost of wave energy projects and facilitate timely, cost-effective environmental review and compliance. A robust approach using numerical models to simulate the WEC devices and array layouts is presented that simultaneously evaluates power production and assesses environmental effects. "WEC-friendly" open-source numerical tools have been developed that are capable of assessing the environmental force on and potential changes to the environment caused by the energy extraction by WEC arrays. A case study is presented to demonstrate how the changes in WEC array configurations can be mapped and quantified using a validated model. A discussion of how changes in WEC devices and array configurations are developed to provide critical information on both engineering and environmental risk. This allows for optimization of WEC deployments to maximize power capture while minimizing environmental impacts.
Considerations and Strategies for Financing Integrated LNG-to-Power Projects
Authors: Viertl Béla , Guccione Danielle
Published: April 2019

The role of liquefied natural gas (LNG) in the global energy system is increasing. In 2000, 11 countries were importing LNG. By 2017, that number had risen to 40 (International Gas Union, 2017). In the Middle East alone, LNG imports have increased by more than 380% over the last three years (S&P Global Platts, 2017). This trend is expected to continue as countries throughout the region, along with others across Asia, Africa, and South America seek to capitalize on cleaner burning and abundant natural gas supplies worldwide.

With increasing population growth and deficits in power generation capacity in many developing parts of the globe, the LNG-to-power concept has emerged as an important driver of future sustainability. However, the costs involved in transitioning power projects to make use of LNG are enormous. One significant challenge that these projects face is the co-development and potential co-financing of the LNG plant, along with supply, distribution and underlying power infrastructure. LNG-to-power projects can also potentially suffer from "project-on-project" risk due to the interdependency of the construction and commissioning of facilities and infrastructure.

Overall, the ability to secure financing from a variety of debt and equity sources throughout the project lifecycle is critical to success. Innovative project financing structures allow for the generation of large debt capacities, while passing project risk to the lenders. In such cases, sponsors are able to assume limited recourse after project start-up and in many cases, enjoy flexibility of loan repayment, thus contributing to overall project economics. Co-financing also alleviates investment risk and helps raise capital at a relatively low cost, which benefits sponsors and investors alike. Financing solutions must be tailored to meet the needs of the project, with risk and returns being borne by the sponsor and different classes of investors (i.e., equity holders, debt providers, quasi-equity investors, etc.).

This paper will discuss the many challenges that must be addressed in order to bring LNG-to-power projects to life, with a particular focus on the unique risk elements that are presented to lenders and investors throughout development.
The Effect of Bayesian Updating in the Hazard Assessment of Submarine Landslides
Authors: Das Roneet , Varela Patricia , Medina-Cetina Zenon
Published: April 2019

This paper introduces a Bayesian methodology to conduct landslide hazard assessment. The proposed approach demonstrates how a probabilistic method can incorporate evolving information about a site for progressively more certain geotechnical characterization. The probabilistic method presented herein is called the Bayesian framework, which integrates a physics-based model defining certain characteristic or phenomenon related to the site, state of evidence on the model parameters, and experimental observations to produce an updated state of evidence on the model parameters and more confident model predictions. This study focuses on landslide geohazard of a site using the physics-based infinite block slope model to estimate the probability of submarine slope failure. The probability of failure against sliding is estimated using the predictions of the infinite slope model under static loading condition for different states of evidence on the model parameters. A state of evidence reflects the level of knowledge about a parameter which describes an attribute of the site such as bathymetry or geotechnical properties of the in-situ soil. This research studies the influence of increasing states of evidence on the confidence gain in model predictions and subsequent updates in the estimates of probability of failure. Predictions based on the infinite slope model are made using the Monte-Carlo algorithm through random sampling of the model parameters. The state of evidence on the model parameters is incorporated in the algorithm by considering the model parameters as random variables following a probability distribution function. These probability distributions, also known as the prior probability distributions, represent the initial state of evidence on the model parameters. The Bayesian framework is used to conduct sequential calibration of the infinite slope model using synthetically generated data on the shear strength of the in-situ soil. These experimental observations represent the state of evidence on the soil conditions. In this paper two sets of data containing 5 and 20 data ‘sample’ points, respectively are used to calibrate the infinite slope model. Calibration of the model results in an updated state of evidence on the model parameters and generates a new set of probability distributions known as the posterior probability distributions. The posterior distributions more accurately describe the potential range of value that the parameters can attain. Comparison between the model predictions based on the initial state of evidence and the updated states of evidence shows a gain in the certainty of the model predictions.
Behavior of Laterally Loaded Offshore Wind Monopiles in Sands

Published: April 2019

The conventional design methods for laterally loaded offshore foundations in sand, API RP 2GEO (2014) and DNV (2018), were not developed for wind turbine monopiles that experience lateral loads imposing relatively small lateral displacements in service. This paper presents the results of research to evaluate the suitability of existing guidance for the design of laterally loaded monopiles at small displacements and to provide recommendations for improving design methods for monopile foundations. The research included applying existing techniques to measure the non-linear stiffness of sand at small shear strains, utilizing a three-dimensional finite element method (3-D FEM) model that incorporates the non-linear stiffness of sand to predict the lateral response of a monopile, testing the proposed approach with foundation model tests in the laboratory, and applying the proposed approach to the lateral load tests conducted on Mustang Island in 1966 that provided the original basis for current design methods.

The following major conclusions are drawn from this research:

Model tests and field tests consistently show that the conventional p-y curves from current design practice tend to underestimate the initial stiffness for laterally loaded piles and fail to capture the non-linearity of the stiffness at small lateral displacements. A 3-D FEM model that incorporates a constitutive model to characterize the small-strain properties of sand, including the maximum shear stiffness at very small strains and the relationships between shear stiffness and both shear strain and effective confining stress, is capable of predicting the response of laterally loaded piles both at model and field scales.

These conclusions lead to the following recommendations for the design of laterally loaded monopiles in sand:

Exercise caution in using conventional p-y curves for sand to predict the performance of offshore wind turbine monopiles in service. The conventional p-y curves used in current design practice do not adequately predict the stiffness and non-linearity of laterally loaded piles at the small lateral displacements relevant for offshore wind turbine monopiles in service. Measure directly or empirically establish the in-situ maximum ("small-strain") shear modulus, the relationship between shear modulus and shear strain, and the relationship between shear modulus and effective confining pressure. These small-strain properties are needed to predict the stiffness and non-linearity of laterally loaded piles at small lateral displacements. Establish improved p-y curves to be used in design directly from 3-D FEM analyses using representative properties of the sand in-situ at small strains.

Authors: Ohrysko Przemysław , Roginskaya Maria
Published: April 2019

In this short note we first extend the validity of the spectral radius formula, obtained by M. Anoussis and G. Gatzouras, for Fourier–Stieltjes algebras. The second part is devoted to showing that, for the measure algebra on any locally compact non-discrete Abelian group, there are no non-trivial constraints among three quantities: the norm, the spectral radius, and the supremum of the Fourier–Stieltjes transform, even if we restrict our attention to measures with all convolution powers singular with respect to the Haar measure.

Disqualification of Company Directors: Safeguarding the Public Interest in the Kenyan Investment Market
Authors: Mwaura Kiarie
Published: April 2019

Over the last two decades, Africa has gone through tremendous economic transformation. It was only in 2004 when the Prime Minister for the UK, Tony Blair, described Africa as the “scar on the conscience of the world” when he was establishing the Commission for Africa. A decade later, he described Africa as “the most exciting continent on the planet because of its opportunities.” Within less than twenty years, the continent has become the world’s most rapidly growing economic region. This economic growth has been attributed largely to the active private sector. Kenya, for example, has realized the highest growth rate in the East African region due to its private sector, which makes a major contribution to the country’s GDP. For this growth rate to continue, African countries need to create competitive legal frameworks that continue to attract investors and protect their interests.One of such is the disqualification framework for company directors that seeks to protect the public by placing a prohibition on a miscreant director from being involved, for a specific period, in the management of companies. An efficient disqualification framework also prevents people without the necessary qualifications from managing companies and deters those who might be tempted to engage in fraudulent activities. Without a strict disqualification framework, investors are unlikely to be attracted to a country, as they risk losing their investments when their companies are managed by incompetent, negligent, or fraudulent directors, especially those with a track record of mismanaging other companies. This philosophy was captured clearly by the Kenyan Government when it enacted the Companies Act 2015 and stated that one of its key objectives was to facilitate commerce, industry, and other socio-economic activities.  It is against this backdrop that this Article examines whether the disqualification framework under the Companies Act 2015 is adequate to protect the interests of investors. This framework is contrasted with the one that existed under the repealed Companies Act 1962 with a view to assessing whether the reforms are likely to bring about the desired changes.

La incorporación de la perspectiva de género en los planes de estudio de la PUCP
Authors: Alegre Henderson Magally
Published: April 2019

En base a tres casos de estudio, la presente investigación analiza el estado actual de la incorporación de una perspectiva de género en los planes de estudio de la Pontificia Universidad Católica del Perú (PUCP). Las Facultades de Estudios Generales Letras y Estudios Generales Ciencias son el punto de inicio en la formación académica de la mayor parte de los estudiantes de la PUCP, lo que justifica su análisis; mientras que la Facultad de Educación es la única en incorporar, de forma explícita, temáticas de género en la curricular, así como, de transversalizar el enfoque en su formación. A partir de una metodología mixta de análisis textual de los planes de estudio y entrevistas a docentes, estudiantes, gestoras y gestores académicos, nos acercamos a los logros, retos y oportunidades en la incorporación de una perspectiva de género en la formación que se brinda en estas tres Facultades.
La Universidad de El Salvador como espacio de reproducción de la violencia de género
Authors: Rodríguez María Angela
Published: April 2019

El objetivo general de la investigación fue caracterizar las expresiones de violencia que se reproducen en el espacio universitario. El estudio es descriptivo, con enfoque mixto, se usó la técnica de la encuesta, aplicada a un total de 655 personas, a través de un muestreo estratificado aplicado en todas las facultades del campus central y de la Facultad Multidisciplinaria de Oriente. Además, se realizaron talleres, grupos focales y entrevistas con autoridades, docentes, personal administrativo estudiantes, sindicatos, gremios y asociaciones estudiantiles, entre febrero y abril de 2018.Los resultados arrojaron que se reproducen todos los tipos de violencia, pero son la psicológica y emocional, y la sexual las más frecuentes, 65.75 % y 15.53 %, respectivamente. Los espacios donde mayormente se reproduce la violencia son las aulas, 41.69 %; cubículos, 14.58 %, y oficinas, un 10.02 %. Contribuyen a esta situación la indiferencia de la comunidad universitaria, los espacios solitarios y el desempeño de la seguridad del personal universitario, como los más determinantes.Las mujeres son las más violentadas, 64.82 %; así como la población LGBTI, con 34.66 %, y los hombres en 18.52 %. Quienes más reproducen dicha violencia, según la opinión de más del 55 % de la consulta, son los hombres de todos los sectores. Señalan que esto se debe a las relaciones de poder, aunado al desconocimiento de derechos por parte de la comunidad universitaria, y el miedo, entre otras.Es innegable que la institución no escapa a los sistemas heteropatriarcal y machista. Pese a la vigencia de un marco normativo sobre los derechos de las mujeres, no se tiene mayor conocimiento del mismo, como tampoco de las instancias internas responsables de la implementación de la legislación. Todo ello contribuye a la falta de denuncia, que también es inducida por el temor y por la poca confianza en los procesos.

Published: April 2019

La desigualdad de género ha sido, en los últimos años, un tema de interés nacional e internacional, particularmente en el ámbito académico. La transversalidad del currículo, incorporando criterios de igualdad de género, es una estrategia de gran alcance, pues la perspectiva de género, vista como objeto de conocimiento, es una categoría analítica que además debe ser tema de estudio desde las universidades. El objetivo principal de este estudio fue identificar la transversalidad del género en la formación profesional de la Universidad Tecnológica de El Salvador (Utec). Es una investigación cuantitativa, de tipo descriptivo; se analizaron 33 planes de estudios, bajo la consigna de revisar en el texto los contenidos, conceptos y palabras que evidencian la incorporación del enfoque de género; se aplicó un instrumento a 310 docentes (108 mujeres y 202 hombres) para conocer la percepción, actitudes y prácticas de igualdad de género en las asignaturas que imparten. Entre los resultados, destacan la incorporación de la prevención de violencia de género como eje transversal en todas las carreras. Asimismo, el personal docente considera que el enfoque de género es un eje transversal en todas las asignaturas; se discuten la práctica de igualdad en el uso de la palabra, el lenguaje no sexista y la necesidad de formar al personal docente para sensibilizar hacia un currículo, explícito u oculto, con perspectiva de género.
Safety checks, monitoring and documentation in medication process in long-term elderly care–Nurses' subjective perceptions
Authors: Karttunen Markus , Sneck Sami , Jokelainen Jari , Männikkö Niko , Elo Satu
Published: April 2019

Objective: Elderly people often use several medicines, which increases risks for side effects and adverse effects. Moreover, most reported adverse events in healthcare are associated with medication. The aim was to describe nursing staffs’ perceptions about and the factors related to the actualization of safety checks, monitoring and documentation in the medication process in long-term elderly care.Methods: This was a cross-sectional quantitative, questionnaire-based study. The response rate, among all nurses working in long-term elderly care wards in a Finnish healthcare district, was 39.4% (n = 492).Results: The results indicate that some safety checks and monitoring guidelines are often violated during the medication administration process, but most nurses self-reportedly maintained good practice in medication documentation.Conclusions: The results suggest needs to review training in pharmacology, infection control, and medication calculations during pre-qualification and continuing education, and to ensure nurses’ awareness of attitudes and ethical considerations for medication safety.
Exploring knowledge landscapes: A narrative inquiry of midwives’ experiences of working in diverse settings in Ghana
Authors: Asamoah Ampofo Evelyn , Caine Vera , Clandinin Jean D.
Published: April 2019

Objective: This paper focuses on exploring the experiences of midwives in Ghana who have worked in diverse settings over time. It explores how midwives’ personal experiences across time, place and in diverse contexts impact their care for women during childbirth. The paper describes the forms of knowledge held by midwives. It presents how the experiences of midwives reflect their professional and personal practical knowledge landscape.Methods: Using narrative inquiry, the experiences of four midwives working in private maternity homes were explored. Being guided by the three-dimensional narrative inquiry space of temporality, sociality and place, and the concept of relational ethics, a meaningful relationship was built with participants over a period of five months. Several tape-recorded conversations were held with each participant, multiple other interactions were recorded as field notes and in a journal. Each tape-recorded conversation was transcribed and used to construct narrative accounts that reflected participants’ experiences as lived and told. Interim narrative accounts were shared with participants to ensure that the accounts reflected their experiences. Analysis: To identify resonant threads across all four narrative accounts, each account was read multiple times with intentionality and with the research objectives in mind.Results: Three distinct professional knowledge landscapes for midwives were identified. These were the professional knowledge landscape of working in rural communities, urban communities, and private maternity homes. Two concepts of knowledge: knowledge for midwives and midwives’ knowledge, were identified on each of these professional knowledge landscapes.Conclusions: Education of midwives should consciously take into consideration the different knowledge landscapes in which midwives in Ghana practice.
Preliminary Study of the Thai Version of the Scale for the Assessment of Negative Symptoms (SANS-Thai)
Authors: Charernboon Thammanard
Published: April 2019

OBJECTIVES: The study aimed to evaluate content validity, convergent validity, internal consistency and test-retest reliability of the Thai version of the Scale for the Assessment of Negative Symptoms (SANS-Thai).

METHODS: The content validity of the SANS-Thai was assessed using four experts. The average-content validity index and item level content validity index were analyzed. The SANS-Thai and the Thai versions of the Addenbrooke’s Cognitive Examination (ACE) were administered to 40 people with schizophrenia to examine convergent validity and internal consistency. Twenty participants took the second SANS-Thai assessment within four weeks to evaluate test-retest reliability.

RESULTS: The results demonstrated that the SANS-Thai has excellent content validity with the average-content validity index of 0.94. The majority of the item level content validity index range from 0.75 to 1. The global and total SANS-Thai score moderately correlated with the ACE with the correlation coefficient of -0.48 (p = 0.002) and -0.49 (p=0.001), respectively. Internal consistency by the Cronbach alpha coefficient was 0.95. Test-retest reliabilities by intraclass correlation were 0.91 (p<0.001) for global SANS-Thai and 0.9 (p<0.001) for total SANS-Thai. The Bland-Altman plot demonstrated that only 5% of the participants fell outside the limits of agreement for both global SANS and total SANS scores.

CONCLUSION: The SANS-Thai appears to be a valid and reliable measure of negative symptoms in schizophrenia and could be useful for patient care and research studies.
Improve of Footwear Comfort Sensation with Material Packages and Knitted Fabrics
Authors: Serweta Wioleta , Olejniczak Zbigniew , Matusiak Małgorzata
Published: April 2019

The main goal of this paper was to analyse the hygienic properties of textile packages used for the construction of shoe uppers. Distance fabrics with varied hygienic properties were the basis of these packages. The discomfort indexes, which describe changes in footwear microclimate, were calculated according to the moisture absorbance capacity and temperature changes in the immediate surrounding of the foot skin surface. The experiment was done for a group of grain leather uppers, where the Grubbs test (a = 0.05) gave positive information about the outliers, describing such parameters as the water vapour permeability and water vapour coefficient. The phase changes of the shoe microclimate were detected via temperature and relative humidity sensors during simulation of the shoes used via an elliptical trainer for a group of 7 men. Statistically significant differences between the packages’ upper – lining confirmed the possibility of monitoring the circulation of biophysical mediums inside a footwear volume. The appropriate choice of package materials could raise the comfort conditions for users. For certain material configurations the microclimate conditions described by the discomfort index were improved.
Physical activity in free time of physical education teachers from Tarn
Authors: Ziemba Anita
Published: April 2019

Aim: The goal of the study was to evaluate the physical activity of physical education teachers from Tarnów schools in their free time.
Material and methods: The research is of pilot nature and was carried out in 2018 among 30 teachers, in the 30–50 age group, teaching physical education in primary schools, junior high schools and high schools in Tarnów. The research covered the participants of the subject workshops. The research was carried out by means of a diagnostic survey and a survey technique was used to obtain necessary information and data.
Results: Physical education teachers willingly undertake physical activity during their free time, however, it is usually recreational activity. The teachers most eagerly practice once or twice a week. Male teachers showed greater frequency of physical activity. Practicing sports in the past is reflected in the approach to taking care of health and maintaining physical fitness later in life. The way of spending free time of the examined teachers differs depending on gender.
Conclusions: Systematic participation of physical education teachers in physical activities is not satisfactory, and yet the teacher should set an example and make students aware of how to care for body and physical health.

Aeromagnetic Map Constrains Jurassic-Early Cretaceous Synrift, Break Up, and Rotational Seafloor Spreading History in the Gulf of Mexico
Authors: James Pindell , Ernesto Miranda C. , Alejandro Cerón , Leopoldo Hernandez
Published: April 2019

We present a reduced-to-pole, total magnetic intensity map derived from merged aeromagnetic surveys in and around the Gulf of Mexico. Most of the deep central Gulf crust has a magnetic pattern of orthogonally intersecting features similar to, and interpreted as, fracture zones and ridge segments of oceanic crust formed by seafloor spreading. This spreading or drift phase occurred after the primary synrift phase of continental stretching across the greater Gulf of Mexico region, and thus the ocean crust rests within a broader zone of stretched continental crust with Yucatán, western Florida, the southern USA, and eastern Mexico forming the surrounding continental margins. We identify three regional magnetic anomaly trends that can be used to constrain the Gulf of Mexico’s Late Jurassic through earliest Cretaceous spreading history. A central magnetic anomaly trend is interpreted to accord with the later increments and cessation of seafloor spreading, for which a stage pole of rotation is estimated. Two flanking magnetic anomaly trends to the north and south of the central one, respectively, occur just basin-ward from the inferred depositional limits of autochthonous Callovian-Early Oxfordian salt. These anomalies appear to define the landward limits of oceanic crust in the northern and southern Gulf, and probably lie in crust that is medial or Late Oxfordian in age. They have similar mapped patterns that can be reconstructed onto one another and hence are probably genetically related but separated by spreading. These landward anomalies are best fit around a different stage pole than the central anomaly; thus the rotation pole appears to have jumped during spreading in the Gulf. Seismic reflection data show that the two outer anomalies occur at the basement “step ups” to the oceanic crust or the basinward shoulders of the “outer marginal troughs.” Until specific magnetic source modelling is done on the outer anomaly pair, we favor an edge-effect interpretation caused by the intrusive interface between Oxfordian oceanic crust and serpentinized and exhumed subcontinental mantle, the latter of which we infer forms the step ups to the oceanic crust. In addition, the aeromagnetic map shows a north-south trending “Campeche Magnetic Anomaly” downslope from the western shelf edge of Yucatán that we argue helps to constrain the reconstruction of Yucatán along Texas at the start of the synrift stage. Thus, the aeromagnetic map provides vital insights into the kinematics of all three stages of the basin's development, namely the synrift, the drift, and the interpreted intervening transitional phase of crustal hyperextension/mantle exhumation along the Gulf’s magma-poor continent-ocean transitions.
Pre-Albian Biostratigraphical and Paleoecological Observations from the De Soto Canyon Area; Gulf of Mexico, USA
Authors: Weber Ryan D. , Parker Brandon W.
Published: April 2019

A biostratigraphical review of eight exploration boreholes located within the De Soto Canyon protraction area in the Gulf of Mexico yields a repeatable and predictive evolutionary and paleoecological sequence with implications to paleogeography. The Oxfordian section within these boreholes contains primitive planktic foraminifera such as Globuligerina oxfordiana. Near the end of the Kimmeridgian (or slightly above the nannofossil Calcivascularis cassidyi extinction), nannofossils are of low abundance, and dominated by Cyclagelosphaera spp. Weakly developed benthic foraminifera abundance gives rise to Reinholdella A which is coincident with a nannofossil dominance switch to Polycostella spp. Planktic foraminifera are not observed in this section

In the overlying section, the extinction of nanno-fossil genus Polycostella, the origination and dominance of Nannoconus, and minute benthic foraminifera gradually increase. Here, the suggested datum, Polycostella beckmanii extinction, is observed consistently higher than the Reinholdella A extinction in the early Tithonian. The fossil assemblage change through this section suggests a change in water masses, which has implications to major reorganization in oceanic circulation.

The Lower Cretaceous continues with multiple nannofossil originations that persist into the Valangin-ian. Here, a significant, diverse, and abundant benthic foraminifera and ostracod assemblage occurs in multiple, rapid abundance increases followed by gradual upward decreases, suggesting cyclical change in the shallower, upslope paleoenvironments. The cause of cyclical changes is unclear and may be the result of sea level change, progradation, and/or changes in ocean composition.

The Hauterivian to Aptian section varies greatly in thickness with the maximum thickness in the northern De Soto Canyon area and thinning to the south. Nannoconus continues to dominate the nannofossil assemblage through the Aptian; benthic foraminifera and ostracods disappear rapidly during the Hauterivian and remaining sparse until the Albian when there is an increase of Nezzazata spp. The significance of these fossil sequences and respective assemblages are discussed in a paleoecological and paleogeographical context, which has implications to depositional history and correlation.
A potência edu(vo)cativa da arte contemporânea: desafios e possibilidades
Authors: Valle Lutiere Dalla
Published: April 2019

Este texto explora a potencia edu(vo)cativa das artes como estratégia metodológica em ambiente escolar. Neste interim, parte-se de uma experiência de aprendizagem compartilhada a partir da exposição “A Translucidez do Corpo” inserida em uma escola de educação básica. Fazendo uso de metodologias interpretativas, buscou-se estabelecer relações de ensino-aprendizagem no campo das artes visuais sobre as três dimensões que constituem a abordagem edu(vo)cativa: educativa, evocativa e cativa. As ações dirigiram-se sobretudo à educação infantil, investigando as relações entre arte, visualidade, imaginário e estudos anatômicos, conhecimentos relacionados ao corpo do ponto de vista da linguagem e da cultura. Como embasamento teórico-metodológico, nos respaldam autores e autoras que dialogam com a perspectiva educativa da cultura visual e pedagogias culturais.
Leonel Brizola e os últimos anos de exílio
Authors: Leite Maria Cláudia Moraes
Published: April 2019

Após o golpe civil-militar de 1964, muitos políticos ligados ao governo deposto encontraram no exílio a chance de escapar das retaliações propostas pelo novo governo militar. Agindo assim, Leonel de Moura Brizola chegou ao Uruguai no início de maio de1964, dando início ao seu período de exílio. Este artigo, entretanto, tem por finalidade analisar os últimos anos de Brizola fora do país, período que vai dos últimos momentos da sua permanência no Uruguai, seguido pela breve passagem pelos Estados Unidos e o término do seu exílio em Lisboa, Portugal. Para atingir os objetivos propostos, buscou-se utilizar um conjunto de fontes que permitisse uma melhor análise da referida problemática – como documentos relativos à burocracia da repressão, imprensa e testemunhos – obedecendo o recorte cronológico proposto e inserindo a pesquisa na denominada História do Tempo Presente.Palavras-chave: BRIZOLA, Leonel de Moura. 1922-2004. Exílio.
A História das Mulheres (séc. XX - XXI): entre poder, resistência e subjetivação
Authors: Tedeschi Losandro Antonio , Tedeschi Sirley Lizott
Published: April 2019

Neste artigo, analisamos a potência produtiva e criativa de práticas de resistência na história das mulheres contra os efeitos das relações de poder instituídas que assujeitam e aviltam a vida. Aproximamo-nos dos estudos pós-estruturalistas e dos estudos feministas e destacamos principalmente as contribuições de Michel Foucault no que se refere à noção de resistência e às reflexões de Gilles Deleuze sobre a obra foucaultiana. Entendemos que as práticas de resistência representam um trabalho sobre si e possibilitam a criação de gestos ativos e transgressores capazes de constituir novos modos de existência, novas subjetividades. A análise mostra que as práticas de resistência na história das mulheres, contra os efeitos de poder do mandato patriarcal, são ações que podemos chamar de menores, de desviantes, mas com força para produzir espaços de liberdade; são forças potencializadoras de outras formas de existência, capazes de compor outras formas de vida; vidas que agem em vez de apenas reagir às práticas instituídas. Nesse sentido, afastamo-nos das concepções que veem nas práticas de resistência apenas oposições ou reações ao poder e buscamos ressaltar que as práticas de resistência instauram fissuras, abalos nos modos de vida estabelecidos e potencializam outras formas de existência. O desafio consiste em encontrar mecanismo para ampliar cada vez mais as ressonâncias desses abalos, dessas fissuras. Palavras-chave: Poder. Subjetividade. Mulheres. História.
Wyrażenia językowe związane z pojęciem zagrożenia wśród słów dnia z roku 2017 – analiza semantyczna
Authors: Szymańska Monika
Published: April 2019

The article presents conclusions from a semantic analysis of a set of linguistic expressions belonging to units selected in the project “Word of the day”, meaning words with the highest relative turnover in particular days of 2017. This collection includes language expressions related to the notion of danger and insecurity. The study is a proposal to look at this group of linguistic expressions from a cognitive perspective, which allows to capture certain common features in the way of perceiving and depicting elements of reality described by them. Referring, inter alia, the cognitive theory of conceptual metaphors and terms, such as profiling, presents some common elements present in the structure of the meaning of the majority of analyzed lexical units. In this way, an attempt was made to reconstruct imaginary patterns a ecting the way of presenting various kinds of threats in press releases.
Modernidad y colonialidad en América Latina. ¿Un binomio indisociable? Reflexiones en torno a las propuestas de Walter Mignolo
Authors: Polo Blanco Jorge , Gómez Betancur Milany
Published: April 2019

This paper reflects upon a decisive issue, namely, the relation between modernity and coloniality in the Latin American context. What remains to be settled is whether European modernity is inherently colonial, or, in other words, whether all modern European thought is indistinguishably and inseparably interwoven with grammars of coloniality that, even today, are reproduced in the arenas of knowledge and power. The guiding thread of this inquiry will be the theoretical proposals of Walter Mignolo, a thinker who argues precisely for the consubstantiality of modernity and coloniality.
