Violencias de género : un conﬂicto a transformar en la educación superior en Colombia
Authors: Otálvaro Marín Bairon , Ceballos Molano Raquel , Bonilla Mejía Lina M. , Wladimir Gómez Carlos
Published: April 2019

El artículo realiza un análisis sobre la presencia de violencias de género en las instituciones de educación superior en Colombia. Se propone una aproximación al concepto de violencia de género y sus tipos: violencia estructural, violencia simbólica y violencia interpersonal, para caracterizar sus diversas formas de expresión en la educación superior. Se acude al enfoque cualitativo para describir en las voces de los entrevistados las posibles causas de la violencia de género en esas instituciones. Las conclusiones apuntan a formular políticas institucionales de género de forma participativa, acciones que pueden promover nuevas miradas sobre la inclusión, protección y el respeto por los derechos y libertades de las mujeres.
Las relaciones de poder en la Educación Superior desde un enfoque de género : mecanismos de inclusión, exclusión y resistencias
Authors: Mamani Colque Ana Esther , Merma Molina Gladys
Published: April 2019

El objetivo general del estudio es comprender y analizar qué tipo de relaciones de poder se desarrollan en la Universidad Boliviana. Se adoptó el enfoque cualitativo que permite recrear en la interacción social y simbólica, ensamblando la voz de los actores. La muestra tiene un carácter intencional no probabilístico, habiéndose efectuado un total de 80 entrevistas a docentes y autoridades universitarias. Se ha diseñado una guía semiestructurada de entrevistas en profundidad y cuadros de observación para el registro etnográfico. Se concluye que las académicas se desenvuelven de forma diferente que los docentes en la gestión y en la política universitaria; su desempeño profesional está marcado por tres tipos de mecanismos: de inclusión, de exclusión y de resistencias, con claro predominio del segundo. Los factores que determinan el funcionamiento de estos mecanismos son la cultura organizacional androcéntrica de la universidad, el contexto familiar y la propia subjetividad de las docentes. Prevalece consistentemente el habitus del “deber ser mujer-esposa-madre-profesional-ama de casa” que configura la ideología vigente de la multifuncionalidad de la mujer. En suma, hay poder activo y real de los hombres y otro poder pasivo de las mujeres que plantea la necesidad de hacer una crítica de la posición que ocupan hombres y mujeres, y de las valoraciones subjetivas que las personas y los colectivos tienen acerca de las relaciones de poder en el contexto universitario.
Visión crítica del currículo desde el enfoque de género e interseccionalidad : caso de la Universidad Central del Ecuador

Published: April 2019

La Universidad Central (UC) ha vivido un proceso académico de disputa epistemológica que se reﬂeja, fundamentalmente, en posiciones discursivas contrapuestas en relación con las conquistas en el ámbito de la igualdad de género: por un lado se expresa un enfoque permeado desde una concepción liberal, que considera que en la actualidad existe igualdad de oportunidades para mujeres y hombres; y que acceder a las diversas conquistas que ofrece la universidad es cuestión de méritos; por otro lado, desde un enfoque feminista, se considera que, aunque se han producido cambios evidentes en las relaciones de género dentro de la universidad, aún existen brechas de desigualdad que se evidencian en sus funciones sustantivas, esto es: en la docencia, investigación y vinculación, así como en la gestión y cultura universitarias. En este sentido, el estudio tuvo como objetivo analizar el currículo a la luz de la teoría crítica de género desde un enfoque interseccional en las carreras de la Facultad de Filosofía, Letras y Ciencias de la Educación de la UC. Este proceso se realizó a partir de la revisión de los rediseños de los proyectos curriculares, para lo cual se diseñó una matriz de diagnóstico de doble entrada: en la primera se definieron los indicadores y en la segunda se diseñó una matriz de evaluación con escala de Likert. Adicionalmente, la metodología utilizada fue cualitativa; y la técnica, de análisis de contenido, pues se leyeron críticamente todas las mallas curriculares y se calificaron 26 ejes que constituyeron la base del estudio. Los resultados demuestran que existe un avance en relación con la incorporación de la categoría de género desde un enfoque interseccional, aunque el eje que tiene mayor visibilidad y fuerza en los rediseños curriculares es el enfoque intercultural y diálogo de saberes, mostrando una corriente que tiende a fortalecer la producción académica de colonial.
Internationalization Context of Arabia Higher Education
Authors: Al-Agtash Salem , Khadra Labib
Published: April 2019

Internationalization in Arabia higher education space is expanding rapidly. It has taken different shapes with no systematic approach to evaluate its success and impact. By analysing patterns of mobility; trends; and forms of academic cooperation in Arabia, a framework for internationalization is introduced. The purpose is to guide efforts towards a strengthened position of higher education in the international dimension. Internationalization promotes the idea of making the university a dynamic cross-boarder educational environment. The higher education space in Arabia is analysed mainly in the internationalization perspective. The German Jordanian University is presented as an illustrative example. The objective is to draw on its experience as a benchmark for devising a workable scenario for implementing internationalization as an important dimension of higher education. The results show the importance of the derived benefits of study abroad, program cooperation, partnership, internship, and research collaboration as essential ingredients of internationalization in higher education systems.
Reviewing the Concept of Green HRM (GHRM) and Its Application Practices (Green Staffing) with Suggested Research Agenda: A Review from Literature Background and Testing Construction Perspective

Published: April 2019

Green HRM has become one of the most critical topics in the Business world and sustainability. Many researchers and studies indicate that environmental green staffing associated strongly with the success of financial and marketplace components. The Green Human resource in green-oriented organisations plays a significant part in shaping the culture of suitability in their organisation. Shaping the practices and applications of the HR with the green view and applications will have an effect on all HR decisions and through all the activity of shareholders viewpoint. Currently, all the work gives more attention to the relationship between GHRM and organisation sustainability. GHRM help in creating, developing and implementing the strategy of sustainable business within the organisation. Although green HRM is still with ground-breaking, unclear define concept and its applications facing some difficulties. The purposes of this study in to present a full theoretical framework for GHRM practices and to test the perspective of the GHRM concept in construction companies in Egypt and the UK. The main finding is the perspective of the UK is higher than Egypt in realizing GHRM important to the organisations.

Work first’, women later? Labour market participation of female refugees.

The labour market participation of recent female refugees in the Netherlands is very low. This is caused not only by the fact that a large proportion of the female refugee population has a greater distance to the labour market (than male refugees), but also because municipalities – for various reasons – offer more support to male refugees seeking to enter the Dutch labour market. This article is based on an explorative study we carried out into the labour market opportunities of recent female refugees and job guidance policies of Dutch municipalities. First, we explore how background characteristics of the group of female refugees and the municipal focus on supporting male refugees to quickly join the workforce, influence each other negatively and greatly limit the chances of female refugees at finding paid work. We then discuss the consequences for the participation and integration of these newcomers and their families, both for the short and long term. Finally, we discuss how female refugees can be supported more effectively towards labour market participation.

Step by step. The perspective of refugees on interventions for labour market participation in several Dutch municipalities.

The groups studied for this article came to the Netherlands as asylum-seekers, mostly from Syria and Eritrea. After receiving a residence permit it has been difficult for them to find paid work. In recent years many municipalities in the Netherlands developed initiatives to support refugees seeking work. In this article we describe two of such interventions: Vluchtelingen Investeren in Participeren (Refugees Invest in Participation), a nationwide initiative of VluchtelingenWerk Nederland, and NVA Werktrajecten (Trajectories to Work), carried out by a local organisation for integration and participation of refugees. We studied VIP in nine municipalities in the eastern part of the Netherlands and NVA Werktrajecten in the Dutch municipality of Amersfoort. We have focused on the perspective of the participants taking part in the initiatives. The research questions addressed are: How did the participants experience the interventions and how did the interventions meet up to their needs in their search to paid work? We describe the experiences of the participants during several steps in the trajectories, such as obtaining practical skills, practising oral and written presentations, meeting employers during the training and in the workplace, and gaining work experience. The article is based on sixty in depth interviews with refugees.
Het asielzoekerscentrum als buurthuis? Over vrijwilligerswerk in asielzoekerscentra in Amsterdam en Brussel

The asylum centre as community home? About voluntary work in asylum centres in Amsterdam and Brussels.

Citizens are being activated to organize activities in asylum centres in both the Netherlands and Belgium. That way, asylum centres are expected to become better integrated in the local context of a municipality or neighbourhood. This ideal of citizenship does not stand on its own. The policy object to integrate asylum centres in the local context has parallels with broader societal and academic discussions about citizen participation and active citizenship. The object, however, is now the asylum seeker. In this article we research how voluntary work in two asylum centres takes shape and how policy could support voluntary activities better. A comparative interpretive policy analysis of two asylum centres in Amsterdam and Brussel shows how voluntary work is stimulated by policy, how these policies are implemented locally, and how they are experienced in daily practices of volunteers and professionals. The cases reveal stark differences, but exactly those contrasts lead to important lessons. We show that because of this policy, the asylum centre is often functioning as a community centre, that integration can be strengthened by volunteers, but we are also critical when voluntary activities are driven by an ideal picture of the ‘good asylum seeker’. There is a risk that the societal responsibility for integrating and engaging asylum seekers in the local context is pushed on the shoulders of unpaid volunteers and that activities are exclusively for one group. That is why we conclude that professional support and financial resources are crucial to implement the policy ideal of active citizenship in asylum centers.

Het punitieve karakter van de Educatieve Maatregel Gedrag en verkeer (EMG)
Authors: Huurman Victor
Published: April 2019

The punitive nature of the Dutch ‘Educational Measure Behaviour and traffic’ rehabilitation course (EMG)

This contribution deals with the punitive aspects of the Dutch ‘Educational Measure Behaviour and traffic’ rehabilitation course (EMG), thereby using the criminal charge concept (article 6 ECHR) and the alcohol interlock case law as indicators for the level of punitivity. As of 2009, Dutch drivers whom (repeatedly) commit traffic violations may be subjected to an EMG. Failing this course can cause a driver to have his or her driving licence suspended. The Dutch Driving Test Organization (CBR) lacks the possibility to take any individual circumstances into account. The question then arises as to whether the EMG may have a disproportionate impact in certain cases. It is argued that the imposition of the EMG predominantly qualifies as a criminal charge, requiring an extension of the current regime of legal protection. It is furthermore argued that the dominant position of the police officer who makes an EMG report should be reconsidered.

A European Public Prosecutor’s Office: opportunities and risks

By the end of 2020, the European Public Prosecutor’s Office (EPPO) will be operational. The EPPO will be tasked with investigating, prosecuting and bringing to judgement criminal offences against the EU budget. The substantive competence of the EPPO could in the future be extended to terrorism and other serious cross-border crimes. This article will first describe the background, structure and competences of the future EPPO. Then the procedural guarantees will be discussed and the problem of ‘forum shopping for evidence’. This problem entails that the choice in which Member State to conduct an investigative measure could be made on the basis of the less stringent rules in that Member State regarding, for example, the right to privacy. The article will end with a proposal on how to prevent forum shopping for evidence.

Material and methods: It was conducted in a group of 30 participants with chronic low back pain in whom, before and after the twelve-week Pilates exercise interventions, the level of subjective pain tolerance (VAS scale), lumbar spine mobility and the degree of quality-of-life impairment were assessed.
Results: Involvement in the Pilates exercise programme helped to reduce subjective pain complaints, improved the spinal range of motion in all planes and enhanced the quality of life in all participants.
Conclusions: The Pilates method is an effective tool in treating chronic low back pain.
The Influence of BMI Value and the Percentage of Fat Tissue on the Curvature of the Foot Longitudinal Arch among Students of University of Physical Education in Krakow
Authors: Madejski Przemysław , Bac Aneta , Madejski Roger
Published: April 2019

Introduction: The foot is an essential element of the kinetic system. Performing the supporting function, it maintains the correct body posture, but above all it is used while walking. Feet are vulnerable to all the changes that occur in human environment. The civilisation changes are particularly harmful to the locomotor system.
Material and methods: The research was conducted in the academic year 2014/2015 among the second year Physiotherapy and Physical Education students in the University of Physical Education in Kraków. The total of 93 students took part in the research (48 females and 45 males). The average age of the subjects was 21 years. In order to assess the curvature of the foot longitudinal arch a podoscope was used, whereas the Tanita BC-418 scales were applied to define the BMI value and calculate the percentage of body fat tissue.
Results: A vast majority of the subjects (70.9%) had a normal type of foot longitudinal arch. Higher longitudinal arch occurred more frequently among women than men, the normal type was less frequent. The BMI level was also within the norm among the majority of the students (79.6%). Overweight was more frequent among males than females. Both males and females with the correct BMI value in their majority had normal curvatures of both feet longitudinal arches. The highest percentage (75%) of the regular right foot longitudinal arch was recorded among females with low body fat deposition. In the case of the left foot the percentage was 68.8%. All the males with low fat deposition obtained normal values of the longitudinal arch curvature for both feet.
Conclusions: The subjects most frequently had a regular curvature of foot longitudinal arch. No significant influence of the percentage of fat tissue and BMI value on the Clarke’s angle was recorded.
Social worker's experience with regard to counteracting domestic violence on the basis of the project "A shelter for years is a house, mom and dad” – A child-friendly patrol
Authors: Sekunda Agnieszka
Published: April 2019

The project “Shelter for years is home, mom, dad” – child-friendly patrol was created out of concern for the safety of children and to promote the correct patterns of family life – without violence, and addiction. Municipality Welfare Centre in Sosnowiec and the local Police Department noticed the possibility of being partners who could help each other in solving problems related to working with dysfunctional families. The cooperation of these two institutions has been to minimize the traumatic experiences of children and to start a family support system in solving its difficult life situation. Very quickly, in Sosnowiec, the first effects and effectiveness of 'child-friendly patrol' were noticed. Other institutions and organisations began to join in cooperation that helped in achieving it, thus gaining the trust of the inhabitants of Sosnowiec and increasing their effectiveness in helping people in need. Thanks to the partnership project, a broadly understood interdisciplinary cooperation for people experiencing violence and people using violence has developed. The system of helping/protecting children against the injured parties was has also developed through joint activities.
Inspired by image: A multimodal analysis of 10th grade English school-leaving written examinations set in Norway (2014-2018)

Published: April 2019

AbstractWhat role does multimodality play in assessment in the English subject in Norway? This article focuses on final written examinations from 2014 to 2018 and investigates the multimodal literacy skills that examinations invite lower secondary school students to demonstrate. Examinations in the English subject are digital and technically open to a rich multimodal practice. Analysis in this article finds that the texts to be read in examinations are carefully designed multimodal texts, with plentiful use of visual aspects of writing and with images that add significantly to the creation of complex cohesive ensembles. When it comes to the examination tasks, however, the opportunity for the students’ multimodal output is limited and ambiguous. In sum, there is an imbalance between input and output.Keywords: multimodal literacy, multimodal texts, English, assessment, lower secondary schoolInspirert av bilder: En multimodal analyse av sentralt gitt skriftlig eksamen for 10. trinn i engelsk i Norge fra 2014 til 2018SammendragHvilken rolle spiller multimodalitet i engelskfagets vurderingspraksis i Norge?

Gulf of Mexico Tectonic Evolution from Mexico Deformation to Oceanic Crust
Authors: Norton I.O. , Lawver L.A. , Snedden J.W.
Published: April 2019

Extended Abstract

Although the final stage of formation of the Gulf of Mexico is fairly well constrained, earlier evolution is still debated. The final stage was rotation of Yucatan about a Florida Straits Euler pole that created most of the observed oceanic crust (Pindell and Dewey, 1982). From observations of salt overlying seaward-dipping reflectors (diagnostic of volcanism during the rift to drift transition) in the northeast Gulf of Mexico, we suggest that salt was deposited at the onset of sea floor spreading, which coincides with initiation of the rotational motion of Yucatan. It is important to understand Yucatan motion that preceded this rotation because delineating any presalt play that might exist would be dependent on understanding of depositional systems developed during this early motion of Yucatan. Very little is known about the nature of presalt deposition in the northern Gulf of Mexico. Salt is Callovian or earliest Oxfordian in age, and the next oldest rocks known from the northern Gulf of Mexico are Late Triassic red beds found in what are generally regarded as proximal grabens formed during early rifting. This gap in knowledge, what we refer to as the “50 million year gap,” can potentially be bridged by incorporating analogs with known systems in Mexico and northern South America. There are uncertainties here, however, mostly based on how Mexico and northern South America are palinspastically restored and the fact that these rocks are in a proximal location. In particular, we note that there was a long-lived continental margin arc in Mexico that lasted from the Permian through the Middle Jurassic (Barboza-Gudino et al., 2012). A lot of the rocks of this age seen in Mexico that are linked to Gulf of Mexico rifting are in fact associated with this arc. In this presentation, we will review reconstructions of the region and develop a tectonic model that forms the basis for further understanding of rifting in the Gulf of Mexico.
Relationship Between the Depositional Episodes of the Woodbine/Eagle Ford of East Texas and the Eagle Ford of South Texas
Authors: Denne Richard , Breyer John
Published: April 2019

A chronostratigraphic framework was developed for the subsurface Eagle Ford of South Texas in conjunction with a log-based regional study that was extended across the San Marcos Arch and into East Texas using biostratigraphic and geochemical data to constrain log correlations of 12 horizons from 1729 wells in South and East Texas. Seven regional depositional episodes were identified by the study. The clayrich Maness Shale was deposited during the Early Cenomanian in East Texas and northern South Texas where it correlates to the base of the Lower Eagle Ford. After a fall in sea-level, East Texas was dominated by the thick siliciclastics of the Woodbine Group, whereas in South Texas deposition of the organic-rich EGFD100 marls of the Lower Eagle Ford began during the subsequent Lewisville transgression. A shift in depositional style to the limestones and organic-rich shales of the Eagle Ford Group occurred in East Texas during the Middle-Late Cenomanian EGFD200 and EGFD300 episodes produced by the continued rise in sea-level. Erosion along the Sabine Uplift shifted the focus of deposition in East Texas southward to the Harris delta and deposited the “clay wedge” of northern South Texas during the EGFD400 episode. The introduction of an oxygenated bottom-water mass onto the Texas shelf produced the considerable decrease in TOC preservation that marks the Lower/Upper Eagle Ford contact. This event coincided with the onset of Oceanic Anoxic Event 2 (OAE2) and the Cenomanian-Turonian Boundary sea-level high, which starved much of the Texas shelf of sediment. The only significant source of sediment was from the south; within the study area, the EGFD500 interval is essentially absent north of the San Marcos Arch. Deposition recommenced on much of the Texas shelf during the Late Turonian EGFD600 episode with the Sub-Clarksville delta of East Texas and the carbonate-rich Langtry Member of South Texas and eastern West Texas. Bottom-waters became oxygenated at approximately 90 Ma, initiating the transition from the Eagle Ford Group to the Austin Chalk.
The Mesozoic of Nuevo Leon, Mexico: An Ancient Extension of the Gulf of Mexico. Paleogeography and Tectonics
Authors: Longoria Jose F. , Rogelio Monreal
Published: April 2019

The Mesozoic of Nuevo Leon is composed of more than 10,000 m of sedimentary rocks displaying abrupt physical changes and containing abundant planktonic foraminifera, allowing precise chronostrati-graphic determinations. This succession has been deposited in the western extension of the ancestral Gulf of Mexico (Mexican Sea). Its paleogeographic setting corresponds to the oblique subduction of the Kula-Far-allon plate under the North American plate. Active oblique subduction of the western margin of Mexico has resulted in the structural features of the Mesozoic sedimentary cover, forming a folded belt made of an intricate array of mountain ranges corresponding to the Nuevo Leones Cordillera characterized by: (1) kilomet-ric-scale anticlinal ridges and narrow synclinal valleys of the Jurassic-Cretaceous sedimentary cover commonly displaying box (fan-shaped) folds; (2) a well-developed pattern of en echelon anticlinal folds; (3) juxtaposition of tectonostratigraphic domains; (4) asymmetrical, overturned, doubly plunging anticlines evolving into faulted anticlines; (5) disrupted, long and sinuous fold trends; (6) lack of large horizontal displacement due to overthrusting; (7) folding being predominant over faulting; (8) local thrusting with opposite vergence; and (9) lack of volcanism and regional metamorphism. Those features are the result of transpressional tectonics since the mid-Jurassic including a greater basement involvement in the tectonic deformation.

Analysis of the megastructures exposed in the region using SIR-A and LANDSAT imagery of northeast Mexico revealed that the megastructures of the Mesozoic Cordillera between parallels 22°00' and 26°00' and meridians 99° 00’ and 101°00’ can be referred to deformation of the thin sedimentary cover above transcurrent faults following the morphological pattern of the lab experiment by Odonne and Vialon. The folding styles of the Nuevo Leones Cordillera were analyzed in light of tectonic transpression and wrench-fault tectonics driven by transcurrent faults in the basement as established by Harland, Lowell, and Beck, resulting in the recognition of subsurface faults in the basement. We associate the geometric arrangement of the megastructural trends to sense of displacement of strike-slip (transcurrent) faults and fold patterns as demonstrated by Odonne and Vialon (1983) and the well-known strike-slip tectonic setting of New Zealand as described by Bishop (1967).
Triple-Porosity Diagram Proposed to Characterize Complex Carbonate Reservoirs—Examples from Mexico
Authors: Colin Stabler
Published: April 2019

Limestone and dolomite reservoir rocks are by far the more important producers of oil and gas in Mexico compared to sandstone reservoirs. Many of the carbonate reservoirs are complex in that they display three types of pores: matrix porosity; vugs, and cavernous porosity; and fracture-induced porosity. This combination of three types of porosity can be described as “triple porosity.” Each pore type presents a different pore-throat size range and each has a different effect on permeability.

In order to better characterize these reservoirs, this paper proposes to visualize the relative abundance of each of these three pore types by plotting them on a triple-porosity pore-type ternary diagram (Fig. 1). Figure 1.Triple-porosity pore-type ternary diagram showing comparisons with previous dual porosity methods. Also shown are areas on the diagram where the main facies of carbonate reservoirs in Mexico plot.
Cenomanian Gulf of Mexico Paleodrainage from Detrital Zircons: Source-to-Sink Sediment Dispersal and Prediction of Basin-Floor Fans
Authors: Blum Mike , Milliken Kristy , Frederick Bruce , Snedden John
Published: April 2019

U-Pb dating of detrital zircons in fluvial sandstones provides a method for reconstruction of drainage basin and sediment routing systems for ancient sedimentary basins. This paper summarizes a detrital-zircon record of Cenomanian paleodrainage and sediment routing for the Gulf of Mexico and U.S. midcontinent. Detrital zircon data from Cenomanian fluvial deposits of the Gulf of Mexico coastal plain (Tuscaloosa and Woodbine formations), the Central Plains (Dakota Group), and the Colorado Front Range (Dakota Formation) show the Appalachian-Ouachita orogen represented a continental divide between south-draining rivers that delivered sediment to the Gulf of Mexico, and west- and north-draining rivers that delivered sediment to the eastern margins of the Western Interior seaway. Moreover, Cenomanian fluvial deposits of the present-day Colorado Front Range were derived from the Western Cordillera, flowed generally west to east, and discharged to the western margin of the seaway. Western Cordillera-derived fluvial systems are distinctive because of the presence of Mesozoic-age zircons from the Cordilleran magmatic arc: the lack of arc zircons in Cenomanian fluvial deposits that dis-charged to the Gulf of Mexico indicates no connection to the Western Cordillera.

Detrital zircon data facilitate reconstruction of contributing drainage area and sediment routing. From these data, the dominant system for the Cenomanian Gulf of Mexico was an ancestral Tennessee River (Tuscaloosa Formation), which flowed axially through the Appalachians, had an estimated channel length of 1200-1600 km, and discharged sediment to the east-central Gulf of Mexico. Smaller rivers drained the Ouachita Mountains of Arkansas and Oklahoma (Woodbine Formation), had length scales of <300 km, and entered the Gulf through the East Texas Basin. From empirical scaling relationships between drainage-basin length and the length of basin-floor fans, these results predict significant basin-floor fans related to the paleo-Tennessee River system and very small fans from the east Texas fluvial systems. This predictive model is consistent with mapped deep-water systems, as the largest fan system was derived from rivers that entered the Gulf of Mexico through the southern Mississippi embayment.
Mesozoic Structure and Petroleum Systems in the De Soto Canyon Salt Basin in the Mobile, Pensacola, Destin Dome, and Viosca Knoll Areas of the MAFLA Shelf
Authors: Pashin Jack C. , Guohai Jin , Hills Denise J.
Published: April 2019

Large parts of the De Soto Canyon Salt Basin are unexplored, and structural and petroleum system models may facilitate continued hydrocarbon exploration, as well as the development of geologic CO2 storage programs. The basin contains four structural provinces: (1) Destin fault system, (2) salt pillow province, (3) diapir province, and (4) salt roller province. The Destin fault system bounds half grabens that formed near the updip limit of salt. The faults have variable displacement and were active mainly during the Cretaceous. Broad salt pillows occur basinward of the Destin fault system, and the largest of these structures forms the core of Destin Dome. Salt pillows basinward of Destin Dome began forming shortly after Smackover deposition, whereas Destin Dome largely post-dates the Destin fault system. The diapir province is in the structurally deepest part of the salt basin, and diapirism occurred from the Jurassic into the Tertiary. The salt roller province contains a complex array of normal faults and rollover structures that record gravitational shelf spreading during Jurassic time. Petroleum systems analysis indicates that the basin contains a distinctive suite of source rocks, sealing strata, reservoir strata, and trap types. Exploration efforts have thus far proven successful in structures that formed before or during hydrocarbon expulsion, and many such structures remain untested.
Albian Stratigraphy of the San Marcos Platform, Texas: Why the Person Formation Correlates with Upper Fredericksburg Group not Washita Group
Authors: Scott Robert W. , Campbell Whitney , Hojnacki Rachel , Lai Xin , Wang Yulun
Published: April 2019

Uppermost Aptian-Albian-lower Cenomanian strata of the Texas Comanchean Series represent three long-term transgressive-regressive cycles: the Trinity, Fredericksburg, and Washita groups that are composed mainly of marine limestone and shale. Each group is composed of shorter term deepening-shallowing cycles. On the Central Texas San Marcos Platform and its downdip equivalents, subsurface strata above the Trinity Group are grouped into the Edwards and Washita groups. Correlations in the 1960s were based on wireline well logs and inferred biostratigraphy that correlated the upper Edwards Group Person Formation with the lower parts of the Washita Group. This correlation crosses a widespread subaerial unconformity that separates the Washita from the underlying Fredericksburg in the northern East Texas Basin and in the Fort Stockton Basin. New biostratigraphic and sedimento-logical data show that the Person actually correlates with the upper part of the Fredericksburg in the Gulf Coast.

Contingencia e identidad: retos para un diálogo transdisciplinar entre la historiografía y la didáctica de la historia
Authors: Simon Cesar Rina , De la Montaña Conchiña Juan Luis
Published: April 2019

En el presente trabajo pretendemos analizar las relaciones entre la historiografía y la didáctica de la historia en el caso español, partiendo de una propuesta fenomenológica sobre los múltiples agentes que conforman las conciencias históricas en las sociedades contemporáneas. La atonía principal entre el conocimiento histórico y su transmisión en las aulas se sitúa en torno a dos conceptos: la identidad y la contingencia. En primer lugar, la historia mantiene en el sistema educativo una función nacionalizadora que obvia la historiografía moderna sobre la temática, ahondando en su condición de imaginario social construido e histórico. El currículo de enseñanza continúa caracterizado por un sentido teleológico y positivista de la historia patria como sucesión de hechos que explicarían el viaje en el tiempo de un ente personificado y homogéneo: la nación. En segundo lugar, analizamos la continuidad de las concepciones deterministas y teleológicas de la historia, que a partir de esquemas causales cerrados pretenden explicar acontecimientos complejos y contingentes. Tanto la función identitaria de la enseñanza de la historia como la noción positivista de la disciplina proyectada a un fin ineludible están en el origen de la historiografía moderna y en su integración en los sistemas educativos de los Estados nación. De ahí que sea necesario reflexionar sobre los usos del pasado e integrar la epistemología, la historiografía y nociones sobre la elaboración del conocimiento histórico y la contingencia en todos los niveles del sistema educativo. Palabras clave: Historiografía. Didáctica de la Historia. Identidad. Contingencia. Progreso.

Reinhart Koselleck e a análise das metáforas: sobre as possibilidades para além do conceitual
Authors: Ramos André da Silva
Published: April 2019

Este artigo explora – em diálogo com estudos recentes no âmbito da teoria da história e história intelectual, especialmente seguindo as perspectivas de Hans Ulrich Gumbrecht e Elías Palti –, os limites da história dos conceitos (Begriffsgeschichte) e a possibilidade da sua dinamização frente à abertura para a análise das metáforas. Pretendo compreender a especificidade da importância conferida por Reinhart Koselleck à análise das “metáforas espaciais” em seu projeto intelectual, diferenciando as perspectivas do autor das de Hans Blumenberg. Evidencio como Koselleck articulou a importância das metáforas em face à centralidade conferida à sua teoria da modernização. Por fim, a intenção será matizar a relevância das contribuições de Koselleck para os estudos historiográficos perante a necessidade da abertura para desafios que não se limitem ao conceitual, como colocado em destaque pela bibliografia especializada contemporânea.Palavras-chave: História dos Conceitos. Teoria da Modernização. Teoria da Não Conceitualidade. Linguagem. Metáforas.
Museus e identidades no tempo presente
Authors: Carmo Aline do , Betencourt Maria Goreti Baptista
Published: April 2019

Pretende-se, aqui, levantar algumas discussões sobre o fazer História do Tempo Presente, com o intuito de dialogar com um fato marcante acontecido em Porto Alegre, no Rio Grande do Sul: o fechamento precoce da exposição Queermuseu – Cartografias da Diferença na Arte, com mais de 270 obras de arte, instalada no Santander Cultural. O grupo de pessoas que pediu o encerramento da exposição reivindicou pura e simplesmente a supressão do seu objeto de desgosto em "arena pública", parecendo ser a nova forma que assume a censura em nosso tempo recente: não mais a decisão do Estado, mas o clamor mais ou menos anônimo, reverberado pelas redes sociais digitais, contra a mera existência do que desagrada uma parcela da sociedade, no caso, as obras com temas sobre a diversidade, corpo e religião.Palavras-chave: História do Tempo Presente.

L’authenticité des images numériques est plus que jamais sujette à suspicion. Signe des temps, les images de presse sont mises sous surveillance. Existe-t-il en littérature un pendant à cette traque au dopage informatique de l’image? A-t-on pareillement besoin de préserver le contrat moral liant l’auteur et le destinataire du texte? Cette méfiance ne cesse de croître, jusqu’à compromettre l’« immersion fictionnelle » nécessaire à la création et à la réception du texte. Le doute serait depuis lors devenu le point focal d’une méfiance partagée.
Art contemporain autochtone
Authors: De Lacroix Pricile
Published: April 2019

Cet article discute de la pertinence d’identifier les arts visuels autochtones comme tel, de maintenir une forme de distinction vis-à-vis des œuvres produites par les artistes autochtones. Il s’agit d’éclairer le débat en soutenant qu’il existe bel et bien certains éléments précis qui permettent encore de définir les arts autochtones. Est également abordé le fait que les artistes continuent d’employer la stratégie claire de l’auto-identification. Sous cet angle, cette catégorie des arts autochtones ne semble pas encore caduque.
De la poésie à l'écran
Authors: Wesley Bernabé
Published: April 2019

Paterson de Jim Jarmusch est une adaptation libre du poème éponyme de William Carlos William et ne parle que de poésie, ce qui pose un défi de taille. Comment inscrire le poétique dans une séquence de plans filmés? Dans une perspective sociocritique, cet article montre comment le film de Jarmusch indexe et retravaille certaines représentations du déclin propres à l’imaginaire social américain contemporain et repose de manière décalée ce qu’il faut bien appeler à nouveau « la question sociale ».
Preliminary experiments with the Andean Condor Algorithm to solve problems of Continuous Domains
Authors: Almonacid Boris L
Published: April 2019

In this article a preliminary experiment is carried out in which a set of elements and procedures are described to be able to solve problems of continuous domains integrated in the Andean Condor Algorithm. The Andean Condor Algorithm is a metaheuristic algorithm of swarm intelligence inspired by the movement pattern of the Andean condor when searching for its food. An experiment focused on solving the problem of the function 1st De Jong's \(f(x_1 \cdots x_n) = \sum_{i=1}^n x_i^2,~ -100 \leq x_i \leq 100\). According to the results obtained, solutions have been obtained close to the overall optimum value of the problem.

The aim of the article is to analyze non-statistic methods of identifying key words (understood as units presenting special importance for a given culture and being a source of knowledge about it). The analyzed criteria of this identi cation are: the presence of the words in the given types of texts and in their speci c parts, undergoing semantic and pragmatic shifts, being a part of phraseo-logical units. The analysis is conducted mainly on the examples extracted form ChronoPress (The Chronological Corpora of Polish Press Texts 1945-1954) from 1945. The e ect of the survey is the evaluation of the abovementioned criteria in terms of their usefulness for identifying key words, followed by a description of the noticed problems and controversies as well as suggestions on finding solutions.

Broadband‐operating active devices within a small‐footprint are highly on demand in various nanophotonic fields such as fiber‐optic communication systems and chip‐based integrated optical circuits. As pioneering approaches, diverse platforms of active metasurfaces (AMs) have been proposed due to their superior tunable functionality and ultra‐compact size. However, most of previous researches provide only limited operating bandwidth because they generally rely on resonant light–matter interaction between active material and plasmonic antenna. In this study, an active wavefront switching metasurface that can operate over 500 nm bandwidth at near‐infrared spectral bands is experimentally realized by utilizing nonresonant U‐shaped Ge2Sb2Te5 nanoantennas. Two different sizes of the U‐shaped antenna are designed to exhibit large transmittance contrast and their optical phases are determined by imposing the orientation angle variation. As an example of the functionality, anomalous refraction angle switching and dispersionless active hologram are demonstrated. The devices provide high signal‐to‐noise ratio (>7 dB) for overall operation bandwidth. It is believed that the proposed AMs can be an innovative platform for real device application thanks to their not only broadband and low‐noise operation but also fast speed, low power consumption switching within a small‐footprint.

Rechargeable magnesium batteries (RMBs) are attractive candidates for large‐scale energy storage owing to the high theoretical specific capacity, rich earth abundance, and good safety characteristics. However, the development of desirable cathode materials for RMBs is constrained by the high polarity and slow intercalation kinetics of Mg2+ ions. Herein, it is demonstrated that 2‐ethylhexylamine pillared vanadium disulfide nanoflowers (expanded VS2) with enlarged interlayer distances exhibit greatly boosted electrochemical performance as a cathode material in RMBs. Through a one‐step solution‐phase synthesis and in situ 2‐ethylhexylamine intercalation process, VS2 nanoflowers with ultralarge interlayer spacing are prepared. A series of ex situ characterizations verify that the cathode of expanded VS2 nanoflowers undergoes a reversible intercalation reaction mechanism, followed by a conversion reaction mechanism. Electrochemical kinetics analysis reveal a relatively fast Mg‐ion diffusivity of expanded VS2 nanoflowers in the order of 10−11–10−12 cm2 s−1, and the pseudocapacitive contribution is up to 64% for the total capacity at 1 mV s−1. The expanded VS2 nanoflowers show highly reversible discharge capacity (245 mAh g−1 at 100 mA g−1), good rate capability (103 mAh g−1 at 2000 mA g−1), and stable cycling performance (90 mAh g−1 after 600 cycles at 1000 mA g−1).
