Effect of Testing Conditions, Gauge, and Temper on Stress Corrosion Cracking of AA7xxx Aluminum Aerospace Plate Alloys
Authors: Warner Timothy , Koschel Diana , Whelchel Ricky , Smith K Paul , Scamans Geoff , Merrill Randall
Published: October 2022

The European Aviation Safety Agency’s recent safety information bulletin (SIB 2018-04R2) describes a brittle intergranular cracking phenomenon in 7xxx aluminum alloys and recommends testing conditions. These testing conditions are severe compared with expectations regarding, temperature, humidity, and stress in aerostructures. In this study, strong increases in time to failure of smooth specimens tested in humid air were observed when reducing either temperature or stress to levels closer to what is representative of in-service conditions. The cracking morphologies after testing in hot, humid air were identical to those described in the literature for in-service occurrences of stress corrosion cracking (SCC), including the observation of crack arrest markings consistent with a mechanism of alternate local corrosion and crack propagation by hydrogen embrittlement. The differences between such fracture surfaces and those observed in the industry standard SCC screening test, which uses a chloride-containing solution to accelerate initiation and propagation, can be attributed to the pitting of the crack surface in a chloride-containing solution in the wake of the propagating crack. The performances of 7xxx-T7 aluminum plates SCC testing in either hot, humid air or a chloride-containing aqueous solution have been compared as a function of thickness, over-aging treatment, and composition. There is a strong effect of plate thickness in both tests, with substantial decreases in initiation time and lifetime for thinner plates. The effect of plate gauge is such that “legacy” materials (such as 7010-T7651, 7050-T7651, and 7050-T7451) passing the SIB 2018-04R2 test at high thicknesses, fail at lower gauges, yet have been flying for nearly 50 y. An increase in SCC performance with increased overaging is observed in both tests. As a consequence, comparisons of SCC performance of alloy compositions should be made wherever possible at identical plate thickness and for aging treatments that result in comparable strengths. When this is done, high Zn concentration 7449-T76++ (7449-T7651 with additional aging) shows a slightly worse strength-SCC balance than 7010-T7651 and 7050-T7651. The observed trends in SCC performance in the two tests are consistent, suggesting that similar repeated initiation and propagation mechanisms are responsible for cracking in humid air and in aqueous NaCl environments.
Saberes estético-corpóreos em “Alma no Olho” de Zózimo Bulbul: possibilidades para uma educação antirracista
Authors: Benatti Lucas Men , Teruya Teresa Kazuko
Published: October 2022

Como dispositivos de enunciação (cultural, social, ideológica) os filmes nos educam, nos ensinam modos de ser e agir no mundo. Cientes desta singularidade do papel cinematográfico, dirigimos nossa atenção as possibilidades (trans)formativas e antirracistas do Cinema Negro brasileiro. Amparados teórica e metodologicamente nos Estudos Culturais e em seus atravessamentos com os estudos étnico-raciais, midiáticos e educacionais, buscamos compreender de que modo o curta-metragem “Alma no Olho”, de Zózimo Bulbul, manifesta saberes estético-corpóreos capazes de apontar para possibilidades pedagógicas antirracistas. Bulbul é reconhecidamente um dos precursores da proposta do Cinema Negro e “Alma no Olho”, objeto de análise da pesquisa, apresenta formulações estéticas afro-diaspóricas de contestação ao regime racista de representação das populações negras. É no interior destas relações (culturais, pedagógicas, raciais, fílmicas) que interrogamos, como problema de pesquisa: de que modo o curta-metragem “Alma no Olho”, de Zózimo Bulbul, manifesta saberes estético-corpóreos capazes de apontar para possibilidades pedagógicas antirracistas? Neste batimento teórico-interpretativo, reconhecemos que o corpo de Bulbul, em “Alma no Olho”, anuncia uma performance filosófica de denúncia ao racismo e ao processo de colonização, e aponta, ao mesmo tempo, para a libertação e afirmação das identidades e dos conhecimentos das populações negras, demonstrando, pedagogicamente, que é possível rompermos com o pacto da branquitude [whiteness] e suas formas de educar.
Flow regime evolution of a major cave system in the Eastern Alps (Hirlatzhöhle, Dachstein)
Authors: Plan Lukas , Buchegger Gottfried , Kaminsky Eva , Koltai Gabriella , Racine Tanguy , Szczygieł Jacek
Published: October 2022

The 116 km-long and 1560 m-deep Hirlatzhöhle is one of the major cave systems in the Northern Calcareous Alps (NCA; Austria). It is located in the NW part of the Dachstein, an extensive karst massif encompassing 576 km² with its highest point at 2995 m a.s.l. In contrast to most other caves in the NCA, Hirlatzhöhle comprises old (epi)phreatic passages located up to 1 km above the base level as well as two modern major drainage systems. The aim of this study is to define the palaeo- and the active flow conditions in combination with speleogenesis, and the age of the cave levels of Hirlatzhöhle. We use morphological as well as sedimentological studies and correlations with other caves. Another difference from cave systems in the NCA is that the majority of passages in Hirlatzhöhle are not developed within the so-called Giant Cave Level between 1200 and 1800 m a.s.l., but deeper between 800 and 1300 m. Most parts of Hirlatzhöhle developed under epiphreatic conditions as indicated by rills and condensation corrosion cupolas, which is the case for much other cave systems in the NCA. In contrast, paragenetic features like canyons and ceiling channels are relatively rare as are insoluble sediments. Elongated scallops indicate that flow velocities were high and abrasive sediments were abundant. Opposite to the nearby Dachstein-Mammuthöhle and other caves east of it that show a west-directed palaeo-flow, scallops in Hirlatzhöhle indicate a NE-directed palaeo-flow and an autogenic recharge. Modern drainage is autogenic and N- to NE-directed as well. Even though burial age dating did not give reasonable results for Hirlatzhöhle yet, the correlation with other adjacent caves suggests a Late Pliocene to Early Pleistocene age of the main palaeo-phreatic level. This is supported by an infinite U-Th age (>0.6 Ma) of a flowstone.
Reconfigurable Gamification Platform for the Autonomous Learning of Low Value Medical Practices
Authors: Fernández César , Vicente María Asunción , Lorenzo Susana , Carrillo Irene , Guilabert Mercedes
Published: October 2022

Failure to follow do-not-do recommendations (also known as low-value practices) is one of the causes of the lack of quality care in all health systems in all countries. Healthcare professionals must be provided with information about these low-value practices that are still frequently performed and their implications for patients and the healthcare system. Continuous education is a key factor in this scenario, so that health students, health professionals, and even patients are kept updated with the main do-not-do recommendations. Gamified platforms are one of the most valuable options for continuous education, as they combine learning efficiency with a high level of engagement for the students. Besides, the effectiveness of gamification platforms can be improved by adding artificial intelligence techniques. In this paper, a novel gamified platform focused on improving knowledge about low-value practices is proposed. AI techniques, as well as NLP tools are used to optimize the effectiveness of learning by adapting the platform to each user, at an individual level. Besides, the engagement of students is encouraged by their participation in a common project, namely the creation of a specialized dictionary for do-not-do terms. Hardware development is currently in progress. A basic gamification platform has already been developed for the two main mobile operating systems. Developing IA and NLP techniques to analyse the training outputs and make the platform adaptable to each student is progressing. The proposed learning tool can significantly improve healthcare quality and be applied to many other learning fields, particularly when continuous training is required.
La Ley 20/2007, de 11 de julio, del Estatuto del Trabajo Autónomo, y el proceso de convergencia del RETA con el Régimen General de la Seguridad Social en materia de acción protectora
Authors: Palomo Vélez Rodrigo Ignacio
Published: October 2022

El Estatuto del Trabajo Autónomo presenta limitados avances en el proceso de convergencia del RETA con el Régimen General de la Seguridad Social en materia de acción protectora, rescatándose algunas mejoras en la intensidad o condiciones de la protección, principalmente mediante la recuperación gradual del principio de obligatoriedad en la cobertura, y matizaciones en la definición y delimitación de algunas de las contingencias protegidas, acercándose más a las establecidas en el Régimen General. A ello hay que agregar el reconocimiento, aunque todavía restringido, de la jubilación anticipada de los autónomos. Sin embargo, esta ley no ha mejorado sustancialmente el contenido mismo de la acción protectora. De hecho, varios temas importantes vuelven a quedar en un estado de latencia, a la espera de estudios, propuestas o informes. Con todo, meritorio es el hecho de que a efectos de la acción protectora la LETA considere, al menos en parte, la diversidad de sujetos que en la actualidad se incluyen en el RETA. En este sentido, merece una valoración positiva el reconocimiento expreso de algunas de las diferencias existentes entre los distintos autónomos que integran el RETA para efectos de protección social (TRADE, autónomos que desempeñan actividades de mayor siniestralidad o actividades de naturaleza tóxica, peligrosa o penosa). Quedan, sin embargo, varios puntos pendientes. Uno de ellos es la reforma en materia de financiamiento, que ciertamente repercute directamente en la acción protectora. Se plantea, por otra parte, debilidad en el tratamiento de algunos temas, como es el caso de la prestación por cese de actividad. Por cierto no se piensa aquí en la convergencia como anhelo político, sino que, sin obviar los necesarios matices que supone la seria convergencia jurídica, no se puede ignorar la necesidad real que de esta protección tiene parte de los autónomos.
Organizaciones saludables y desarrollo de recursos humanos
Authors: Salanova Soria Marisa
Published: October 2022

En este artículo se tratará, en primer lugar, de posicionar la salud, y en concreto la salud en el ámbito del trabajo, y las organizaciones como elemento clave de gestión y desarrollo de los recursos humanos, como un valor estratégico de negocio. Y este posicionamiento se respalda en la investigación científica en un campo novedoso y actual como es la psicología positiva. En segundo lugar, se profundizará en el concepto, significado y alcance de la organización saludable atendiendo a las distintas aproximaciones a su estudio, el concepto mismo de organización saludable, su comprensión como un «buen lugar para trabajar» y el desarrollo de un modelo integrador de organización saludable. En tercer lugar, se atenderá a la cuestión «corazón» de este tipo de organizaciones que es la salud de los empleados entendida como capital psicológico «positivo». Para ello, se parte de la idea de que los empleados son una inversión y una ventaja competitiva, y que se pueden considerar como capital humano, social y psicológico, ateniendo a cada uno de estos conceptos. Finalmente, y desde un planteamiento práctico-aplicado, se intentará responder a la pregunta ¿qué pueden hacer las organizaciones para ser «saludables»? Para ello, se describirán los principales resultados de la investigación científica sobre el desarrollo de recursos saludables en las organizaciones, atendiendo posteriormente a las buenas prácticas desde el desarrollo de recursos relacionados con la tarea, organizacionales y sociales.

Crítica de la Resolución de la Comisión Nacional de los Mercados y la Competencia, de 18 de septiembre de 2020, sobre el Acuerdo Marco de la Estiba
Authors: Ojeda Avilés Antonio
Published: October 2022

La Comisión Nacional de los Mercados y la Competencia ejerce su control transversalmente sobre todas las instituciones españolas, aplicando, sin embargo, conceptos mercantiles, lo cual implica un desajuste que se advierte claramente en la tan esperada y temida resolución que se comenta, donde califica como falta muy grave el acuerdo colectivo para la subrogación de plantillas en las empresas que asumen la carga proporcional de trabajo cuando salen de la extinta Sociedad Anónima de Gestión de la Estiba Portuaria (SAGEP). Aun cuando intenta aproximarse a las instituciones laborales, adolece, no obstante, de una visión excesivamente genérica, donde las peculiaridades del derecho español no quedan salvaguardadas. Esto incide en una interpretación rigorista tanto de la Sentencia del Tribunal de Justicia de la Unión Europea de diciembre de 2014, que consideraba contraria a la libertad de establecimiento en algunas partes de la normativa sobre las SAGEP de entonces, como de otras sentencias de ese mismo tribunal en las cuales hay una consideración amplia de las excepciones laborales a la aplicación del derecho de la competencia.
Implicaciones jurídico-laborales de la COVID-19: lecciones judiciales para garantizar un futuro más seguro
Authors: Fernández Fernández Roberto
Published: October 2022

Este trabajo ha obtenido el Premio Estudios Financieros 2020 en la modalidad de Derecho del Trabajo y Seguridad Social.
La situación provocada por la pandemia de la COVID-19 ha dado lugar no solamente a la declaración de un estado de alarma con una duración nunca vista desde la restauración de la democracia en España, sino también a la promulgación de una gran profusión de normas destinadas a regular la nueva realidad, que ha tenido que aceptar la ciudadanía como consecuencia de la veloz propagación con la que se transmitía la enfermedad. El derecho del trabajo y de la Seguridad Social no ha sido ajeno a la producción normativa excepcional y temporal surgida durante este convulso periodo. En este sentido, además de las disposiciones de contenido laboral recogidas en los reales decretos de alarma, se han dictado un buen número de reales decretos-leyes y órdenes ministeriales que vienen a afectar a instituciones propias de esta área jurídica de conocimiento. Aun cuando todavía es pronto para conocer el alcance de toda la regulación laboral promulgada, el presente trabajo ha pretendido analizar la misma a partir de las resoluciones judiciales que se han publicado hasta el momento en torno a esta regulación, y se puede decir que ya es posible alcanzar ciertas conclusiones parciales sobre determinadas materias en las cuales ya han recaído un número no desdeñable de resoluciones judiciales, en particular en lo que se refiere a la prevención de riesgos del personal esencial, sobre todo del sector sanitario.
Economía de datos, mercados digitales de empleo y gestión analítica de personas: retos para la transición a una «sociedad del e-trabajo decente»
Authors: Molina Navarrete Cristóbal
Published: October 2022

1. Los datos, «nuevas minas de oro» reales del «rey Salomón». Tras varias décadas y diversas generaciones de personas fascinadas por la literatura y la cinematografía, de calidad desigual, cierto, en torno a las aventuras forjadas en la búsqueda de las minas de oro del rey Salomón, la leyenda fue desvelada (lamentablemente), hace algo más de una década, por la ciencia arqueológica: existieron tan célebres minas, pero no fueron de oro, sino de cobre. Desde el inicio de este siglo, la búsqueda de nuevas minas de oro encuentra en los «datos» uno de sus principales referentes, de ahí que la economía cada vez asiente más sus horizontes de desarrollo sobre esta «minería de datos» (se considere en unos casos con la metáfora del oro, siempre presente en la historia de la humanidad, se acuda a la metáfora del petróleo, oro negro, hoy con peor prensa por formar parte de una economía ambientalmente insostenible). No obstante, ya Sherlock Holmes (El misterio de Copper Beeches) era muy consciente de su valor para desvelar la autoría de conductas –en su caso delincuenciales–, a veces incluso antes de consumarlas (función preventiva mediante el análisis de perfiles delincuenciales). La película de ciencia ficción Minority report (Sentencia previa, en América Latina), dirigida en el año 2002 por el laureado director Steven Spielberg, llevará a sus máximas consecuencias esa explotación preventiva del procesamiento de datos masivos de todo tipo.
Última jurisprudencia del Tribunal Supremo sobre despidos colectivos. Una exposición crítica
Authors: Pérez Capitán Luis
Published: October 2022

La jurisprudencia de la Sala de lo Social del Tribunal Supremo, decisiva en numerosos aspectos de la realidad del derecho del trabajo, es aún más relevante en el ámbito del despido colectivo. La exposición y breve análisis de la última doctrina al respecto nos muestra una normativa de despido colectivo con graves carencias y necesidades urgentes de cambio.
Umbrales, causas, conexión con otras instituciones del derecho del trabajo como sucesión o grupo de empresas, criterios de selección son algunas de las importantes materias que la Sala de lo Social ha debido analizar durante el último semestre de 2021. Y si bien no se aprecian grandes cambios en la doctrina que se venía exponiendo al respecto, la consolidación de algunos criterios y la matización de otros a la luz de las nuevas circunstancias propias de un segmento del ordenamiento jurídico sometido a continua tensión determinan la necesidad de una exposición y análisis ordenado de la doctrina del Tribunal Supremo en torno al despido colectivo.

Subcutaneous Injection of Azacitidine for the Treatment of Acute Myeloid Leukemia
Authors: Leung Cynthia , Tingley Kylie , McGill Sarah C.
Published: October 2022

Evidence from 1 randomized controlled trial suggests that subcutaneous azacitidine prolongs disease-free survival among patients with acute myeloid leukemia who have achieved complete remission and who are ineligible for stem cell transplant.

The oral and subcutaneous formulations are different pharmacokinetically. The studied regimens are also very different in the dose and treatment duration per cycle. The approved oral regimen is 300 mg once daily for 14 days per 28-day cycle, whereas the studied subcutaneous dose is 50 mg/m2 per day for 5 days per 28-day cycle.

Given that there is no direct head-to-head comparison between the oral and subcutaneous formulations of azacitidine, there is insufficient evidence to extrapolate conclusions about the clinical effectiveness of oral formulation to the subcutaneous formulation of azacitidine as a maintenance therapy for acute myeloid leukemia.

For the subcutaneous administration of azacitidine, there are potentially additional health care costs associated with handling hazardous medications and the need for trained personnel for administration. More research is needed to inform decision-making in the context of routes of administration.
Immune mechanisms, resistance genes, and their roles in the prevention of mastitis in dairy cows
Authors: Zemanova Monika , Langova Lucie , Novotná Ivana , Dvorakova Petra , Vrtkova Irena , Havlicek Zdenek
Published: October 2022

Abstract. Mastitis is one of the most important diseases of the mammary gland. The increased incidence of this disease in cows is due to the breeding of dairy cattle for higher yields, which is accompanied by an increased susceptibility to mastitis. Therefore, the difficulty involved with preventing this disease has increased. An integral part of current research is the elimination of mastitis in order to reduce the consumption of antibiotic drugs, thereby reducing the resistance of microorganisms and decreasing companies' economic losses due to mastitis (i.e. decreased milk yield, increased drug costs, and reduced milk supply). Susceptibility to mastitis is based on dairy cows' immunity, health, nutrition, and welfare. Thus, it is important to understand the immune processes in the body in order to increase the resistance of animals. Recently, various studies have focused on the selection of mastitis resistance genes. An important point is also the prevention of mastitis. This publication aims to describe the physiology of the mammary gland along with its immune mechanisms and to approximate their connection with potential mastitis resistance genes. This work describes various options for mastitis elimination and focuses on genetic selection and a closer specification of resistance genes to mastitis. Among the most promising resistance genes for mastitis, we consider CD14, CXCR1, lactoferrin, and lactoglobulin.
SAGE III/ISS ozone and NO2 validation using diurnal scaling factors
Authors: Strode Sarah A. , Taha Ghassan , Oman Luke D. , Damadeo Robert , Flittner David , Schoeberl Mark , Sioris Christopher E. , Stauffer Ryan
Published: October 2022

Abstract. We developed a set of solar zenith angle, latitude- and
altitude-dependent scaling factors to account for the diurnal variability in
ozone (O3) and nitrogen dioxide (NO2) when comparing Stratospheric
Aerosol and Gas Experiment (SAGE) III/ISS observations to observations from
other times of day. The scaling factors are calculated as a function of
solar zenith angle from the four-dimensional output of a global atmospheric chemistry model simulation of 2017–2020 that shows good agreement with
observed vertical profiles. Using a global atmospheric chemistry model
allows us to account for both chemically and dynamically driven variability.
Both year-specific scale factors and a multi-year monthly climatology are
available to decrease the uncertainty in inter-instrument comparisons and
allow consistent comparisons between observations from different times of
day. We describe the variability in the diurnal scale factors as a function
of space and time. The quasi-biennial oscillation (QBO) appears to be a
contributing factor to interannual variability in the NO2 scaling
factors, leading to differences between years that switch sign with
altitude. We show that application of these scaling factors improves the
comparison between SAGE III/ISS and OSIRIS NO2 and between SAGE III/ISS and OMPS LP, OSIRIS, and ACE-FTS O3 observations. The comparisons between SAGE III/ISS O3 for sunrise or sunset vs. Microwave Limb Sounder (MLS) daytime or nighttime observations are also more consistent when we apply the diurnal scaling factors. There is good agreement between SAGE III/ISS V5.2
ozone and correlative measurements, with differences within 5 % between
20 and 50 km when corrected for diurnal variability. Similarly, the SAGE III/ISS V5.2 NO2 agreement with correlative measurement is mostly within
10 %. While the scale factors were designed for use with SAGE III/ISS
observations, they can easily be applied to other observation
intercomparisons as well.
Technical note: The recovery rate of free particulate organic matter is strongly reduced by conventional density fractionation of soil samples
Authors: Büks Frederick
Published: October 2022

Abstract. Ultrasonication combined with density fractionation (USD) is a method widely used to quantify soil organic matter pools. A selective fractionation of free particulate organic matter (fPOM) is crucial to avoid co-extraction of retained fPOM along with occluded particulate organic matter (oPOM). In the present work, artificial fPOM was extracted from two mineral matrices, sandy and loamy, after applying different approaches for merging sample and dense medium. It could be shown that pouring the dense solution to the mineral matrices leads to low recovery, whereas trickling the sample into the solution, rotating after fill-up or applying a minimal and defined amount of ultrasound to swirl up the sample causes nearly full recovery of the artificial fPOM. Applied to natural soils, the results confirmed the low extraction rate of the fill-up approach. Moreover, it was possible to show that the rotational approach results in only a slightly increased extraction rate, whereas the ultrasound approach leads to a release of oPOM into the fPOM fraction due to disruption of soil macro-aggregates. The trickle approach appears to be the most appropriate way among the tested methods to achieve complete and selective extraction of fPOM from natural soil samples.
The impact of diffuse light on gross ecosystem productivity over a winter wheat (Triticum aestivum L.) is related to the increase of incident light interception in the middle and lower canopy
Authors: Bao Xueyan , Sun Xiaomin
Published: October 2022

Abstract. Diffuse light has potential to increase ecosystem gross primary productivity without the confounding effect of other environmental factors. However, the magnitude of the importance of diffuse light for ecosystem carbon uptake and the mechanism behind the diffuse light-related photosynthetic enhancement is unclear. Here, 2 years of gross ecosystem primary productivity (GEP), assessed by eddy covariance technology over a (winter) wheat cropland, was used to determine whether diffuse photosynthetic active radiance (PARdif) affected wheat GEP. Additionally, the method of Artificial Neural Network combined with interference analysis and modelling were used to quantify the relative importance of diffuse light for GEP variations and to explore the underlying mechanism of diffuse light effect on GEP. Wheat GEP increased significantly with increase in PARdif in the absence of effect of total PAR. PARdif was found to be the most important factor for wheat GEP, making a contribution of 41.3 % in 2011 and 35.7 % in 2012 to GEP variations, which were greater than the contribution of total PAR, air temperature, vapor pressure deficit and friction velocity. The results of combination of model and measured data indicated that as PARdif increasing, the within canopy, especially the middle and lower canopy, intercepted more light, leading to photosynthetic increase in entire canopy. Over all, our study provided a new evidence for the importance of diffuse light for carbon uptake in agroecosystem, which is importance for predicting the response of ecosystem carbon budget to future light climate changes.
The effect of hydrology and crevasse wall contact on calving
Authors: Zarrinderakht Maryam , Schoof Christian , Peirce Anthony
Published: October 2022

Abstract. Calving is one of the main controls on the dynamics of marine ice sheets. We solve a quasi-static linear elastic fracture dynamics problem, forced by a viscous pre-stress describing the stress state in the ice prior to the introduction of a crack, to determine conditions under which an ice shelf can calve for a variety of different surface hydrologies. Extending previous work, we develop a boundary-element-based method for solving the problem, which enables us to ensure that the faces of crevasses are not spuriously allowed to penetrate into each other in the
model. We find that a fixed water table below the ice surface can lead to two distinct styles of calving, one of which involves the abrupt unstable growth of a crack across a finite thickness of unbroken ice that is potentially history-dependent, while the other involves the continuous growth of the crack until the full ice thickness has been penetrated, which occurs at a critical combination of extensional stress, water level and ice thickness. We give a relatively simple analytical calving law for the latter case. For a fixed water volume injected into a surface crack, we find that complete crack propagation almost invariably happens at realistic extensional stresses if the initial crack length exceeds a shallow threshold, but we also argue that this process is more likely to correspond to the formation of a localized, moulin-like slot that permits drainage, rather than a calving event. We also revisit the formation of basal cracks and find that, in the model, they invariably propagate across the full ice shelf at stresses that are readily generated near an ice shelf front. This indicates that a more sophisticated coupling of the present model (which has been used in a very similar form by several previous authors) needs modification to incorporate the effect of torques generated by buoyantly modulated shelf flexure in the far field.

Like Dancing on Our Turtle’s Back and “Land as Pedagogy,” this book was generated from within Nishnaabeg intelligence — Nishnaabeg intellectual practices or, more broadly, Nishnaabewin — rather than the traditional theoretical and methodological orientations of the Western academy (Simpson 2014; 2013; 2011). It is anchored theoretically within the ways my people generate knowledge, through deep reciprocal embodied engagement with Aki, and by participating with full presence in embedded practices — inherent processes that occur within a series of ethical frameworks that, when adhered to, continually generate consent.
Estudio sociopragmático de los mecanismos atenuadores en el corpus oral PRESEEA-Sevilla
Authors: Repede Doina
Published: October 2022

En este trabajo nos proponemos estudiar los mecanismos lingüísticos de atenuación en el español hablado de la comunidad urbana de Sevilla teniendo en cuenta los criterios de la edad y el sexo. Para ello, manejamos 24 entrevistas semidirigidas correspondientes al nivel de estudios alto que forman parte del corpus oral PRESEEA de la ciudad hispalense (Repede 2019), distribuidas de forma proporcional según los factores sexo ‒ hombres y mujeres‒ y grupo generacional ‒20-34 años, 35-54 años y 55 años en adelante‒. Con el fin de llevar a cabo este estudio, nos basamos en la ficha propuesta por Albelda y otros (2014) para el análisis de la atenuación. Los resultados generales indican que un 22 % de los turnos de habla del corpus están mitigados, en los que se utilizan 1280 recursos de atenuación. Se trata, además, de un fenómeno lingüístico que se manifiesta de manera distinta entre los hombres y las mujeres entrevistadas, así como entre los tres grupos etarios.
Lo que ‘viene siendo’ lo que es: Funciones pragmáticas y variación sociolingüística
Authors: Montoro del Arco Esteban T.
Published: October 2022

El marcador lo que es parece haberse gramaticalizado en español, si bien su uso parece recibir una valoración negativa generalizada. Suele ser categorizado como expletivo o como muletilla, debido a que se considera que no aporta ningún valor al discurso, especialmente cuando su uso es demasiado reiterado. En este trabajo nos proponemos dos objetivos. Por un lado, desde un punto de vista teórico, describimos los valores pragmático-discursivos observados en el uso de este marcador: a los valores característicos de foco y tema, ya expresados por algunos autores, añadimos otros observados gracias al vaciado de dos corpus orales de español hablado en Granada. Por otro lado, desde un punto de vista descriptivo, exponemos la distribución social de los usos de este marcador, teniendo en cuenta los factores de sexo, edad, nivel de instrucción y procedencia (hablantes vernaculares granadinos frente a hablantes inmigrantes procedentes de Ecuador), analizamos su prestigio y abordamos su posible carácter no ya solo dialectal, sino también idiolectal.

The Role of Organizational Slack and Human Capital in Managing Performance Shocks: An Analysis of US Nursing Homes and Hurricane Katrina
Authors: McCrea Austin
Published: October 2022

Public service organizations employ buffers to ward off disruptive performance shocks such as disasters, budget cuts, and uncertain events. Existing applications on buffering focus on how slack human resources are reallocated to high-risk areas during times of uncertainty to dampen the impact these events have on core organizational processes. Besides slack, the quality of human capital is also important. Skilled personnel have the technical acumen and expertise to help managers navigate through treacherous times and still deliver public services. Yet, existing work does not disentangle the distinct impact of these two buffers. Using a panel dataset of nursing homes in Louisiana and Mississippi, I explore how personnel slack and human capital helped mitigate the devastation that Hurricane Katrina had on a very fragile, dependent, and sensitive segment of the population. The findings suggest that human capital buffers the impact of Hurricane Katrina on health deficiencies and physical dependency. In contrast, slack capacity amplified the impact of Katrina on health deficiencies.
E-Government Services Adoption in Uzbekistan: An Empirical Validation of Extended Version of the Unified Model of Electronic Government Acceptance (UMEGA)
Authors: Avazov Shokhrukh , Lee Seohyun
Published: October 2022

E-government is recognized as one of the top priorities among many countries and Uzbekistan is one such country that embarked on e-government implementation. Although a growing body of literature focused on the acceptance of e-government from the citizens’ perspective in different countries, little is known about the Uzbek citizens’ perceptions. In this context, this study aimed to investigate the underlying factors for citizens’ intention to use e-government services called Single Portal of Interactive Public Services (SPIPS) in Uzbekistan. To that end, a theoretical model known as the Unified Model of E-government Adoption (UMEGA) was extended and employed. A survey was conducted for 390 Uzbek citizens to measure six constructs from UMEGA and two additional components, service quality and trust. Results from structural equation model showed that performance expectancy (β=0.680, p < 0.001) and trust (β=0.548, p < 0.001) had the greatest influence on intention to use e-government. These findings suggest policy recommendations for successful diffusion of e-government services in other developing countries and Central Asian countries including Uzbekistan.

Published: October 2022

The purpose of the research is to analyze the concept of public-private partnership and the practice of its implementation in the field of «green» economy to achieve sustainable development of the city.Methodology – the study is based on scientific papers on the topic of public-private partnership, collected from the international databases Scopus, Web of Science for the period from 2008 to 2021. The main research methods include historical and logical methods, observation, analysis and synthesis.Originality / value – the authors present the most common models of public-private partnership in different countries of the world, describe the development of the concept of public-private partnership in Kazakhstan, including the field of "green" economy.Findings. The results of the study demonstrate the growing role of the private sector in the implementation of public-private partnerships to achieve the city's sustainable development goals. The mechanism of publicprivate partnership makes it possible to improve the quality and efficiency of services traditionally provided by the state, while reducing the financial burden on the state budget. The most successful models are publicprivate partnerships in the implementation of urban infrastructure projects based on «green» technologies and «green» financing. However, the number of «green» public-private partnership projects is significantly less than in other sectors of the economy. Currently, conditions have been formed in Kazakhstan for the implementation of the concept of public private partnership, however, in the field of green economy, this concept is not yet fully implemented. The main reason is the low profitability of projects, in this regard, it is necessary to provide in the legislation incentive measures for the development of public-private partnership by simplifying the procedures for concluding contracts, providing tax benefits, subsidies and revising the rates of fees for the provision of services.

Cognitive autonomous networks imply that networks will independently derive and execute intelligent decisions, and thereby elevating the human operator's role to a higher level of abstraction. At that level, the operator only specifies the desired outcomes, called intents, which must then be supported by corresponding intent-driven capabilities in the network or its management functions. Although, Intent-Driven Management (IDM) has been published in multiple works, there is still no globally agreed end-to-end view of such IDM systems, let alone a globally agreed definition of intents. This paper provides a comprehensive discussion on the core aspects of IDM systems and combines them into an end-to-end system view with the related example solutions. Contrasting against a short review of related scientific and standards literature, the paper introduces a flexible, generic definition of intents and an end-to-end IDM system architecture as well as the related modeling of intents to support their standardization. The paper also introduces implementation examples fitting the architecture and discusses advanced IDM features that need to be provided, including the ability to detect and resolve conflicts between intents.
Something Rotten in the State of Gibraltar: M. G. Sanchez’s Autobiographical Explorations of Borderlands
Authors: Habermann Ina
Published: October 2022

This article is concerned with Gibraltar as a hybrid borderland in M. G. Sanchez’s autobiographical works. Sanchez grew up in Gibraltar during the border closure in the 1970s and now lives in England, having traveled widely and lived for some years in Japan and India. A British Gibraltarian writer and in some ways a “nomadic subject,” Sanchez keeps close ties with Gibraltar, where he has family and friends, visiting regularly and taking an active part in Gibraltarian cultural and political debates. In his work, Sanchez explores the palimpsestic quality of Gibraltarian culture, registering the changes in his birthplace while also attending to the traces of the past, the memories and the residue of a colonial culture. In particular, Sanchez sees Gibraltar as a borderscape and a culturally hybrid place preoccupied with borderlines. This article argues that with his approach to writing Gibraltar, Sanchez makes an important contribution to Gibraltar’s current negotiation of identity in times of Brexit.
Microecologies of a Mediterranean Enclave: “Remote” Reading of Datça Peninsula and Its Traditional Villages
Authors: Kütükçüoğlu Burcu
Published: October 2022

Datça Peninsula in southwestern Anatolia has a typically Mediterranean cultural landscape with significant variations among its subregions. This article presents research performed by the author and a group of graduate students of architecture in the summer of 2020, with the aim of discovering and creatively representing Datça’s mosaic of microecological variations. The research focused on the traditional villages of Datça, with eight studied in detail in terms of the natural and manmade elements that define their particular landscapes. Original maps and three-dimensional drawings were produced as the final outcome and display both factual data and students’ interpretations of the spatial characteristics of Datça Peninsula and its traditional settlements. These maps and drawings are based on information gathered from satellite maps, aerial photographs, and written sources and represent the salient geographic features, the borders and subregions, and the visual imagery of the major cultural landscapes within the geographic mosaic of the peninsula. Both the methods and outcomes of the research are products of a collective and experimental study of space literacy and documentation.
